Rice transplanter selection strategy farmers can have a look!

Spring ploughing season is coming, are farmers still worrying about purchasing agricultural machinery and tools? There are many kinds of rice transplanters in the market, so how to choose the one that suits you has become a headache. We should consider that the rice transplanter is affected by the factors such as seedling field, seedling and rice variety in the process of use, and different production conditions put forward different requirements for the transplanter. The selection of rice transplanter by users should be in strict compliance with the conditions of use, and then consider the principle of performance-to-price advantage, so that they can really achieve "useful and good use". The following is to introduce you to the selection strategy of rice transplanter, mainly looking at five aspects:

I. Seedling condition

The blanket seedling used by the transplanter has higher requirements for bed soil thickness, seedling height, seedling root packing and sowing uniformity. The thickness of the standard bed soil is 2.0ml 2.5 cm and the seedling height is 15ml 25cm. The mechanically planted seedlings with uniform sowing and high quality can be raised by one hand without dropping the seedlings.

Choice: the working speed of the high-speed seated transplanter is fast, and the requirements for seedlings are higher. If the thickness of the bed soil is uneven, the roots of the seedlings are not good, and the seedlings are sown unevenly in the seedling tray, it is easy to block the seedlings and hurt the seedlings in the transplanting operation. At the same time, when the seedling platform is positioned at the back, when the operator finds that there is a lack of seedlings, it has often caused a lack of seedlings for a certain distance, which is easy to cause problems such as too much artificial seedling replenishment.

The working speed of the walking transplanter and the three-wheeled transplanter is slow, so it is easy to observe the seedling delivery condition of the transplanting table, and it can be found and adjusted in time even when the seedling is not good, so as to maintain continuous transplanting.

Suggestion: in the areas where the use of rice transplanter is promoted, especially in the areas where seedling cultivation is standardized for the first time, it is suggested that the use of rice transplanter should start with a walking or dragging board transplanter, which can artificially reduce the impact of non-standard seedlings and fields on mechanical transplanting.

II. The situation of the fields

1. The non-continuous seedling distance of the field

In the machine transplanting operation, the number of self-brought seedlings is affected by the machine load and loading space, and the planting distance is about 100 meters, so it is necessary to stop the field to prepare seedlings. Ensuring a certain straight-line transplanting distance is the key to improve the operation efficiency, the ideal distance is about 200 meters, and the ridge distance is too long, which must result in too many seedlings prepared by the transplanting machine, overloading of the machine, serious subsidence of the body, and even unable to work.

Suggestion: if the field is too large, the transplanter may be overloaded, so it is necessary to adjust the distance between the field and the transplanter, and the large power machine should be selected at the same time.

two。 The deep ploughing of the field

The seated transplanter has higher requirements for the depth of the mud foot of the seedling field. General operating conditions require that the appropriate depth of the mud foot is less than 20 cm; once it exceeds 30 cm, the subsidence of the rice transplanter in the load state may reach 40 cm, directly resulting in inability to work, and other power machinery is needed to pull out the sunken ground. Although the rice transplanter is a four-wheel drive device, once the depth of the mud foot exceeds the radius of the front wheel, it will be difficult for the machine to climb and normal operation can not be guaranteed.

Suggestion: the high-speed rice transplanter is limited by the depth of the mud foot, so this requirement should be considered when ploughing the land at the initial stage. Once the depth of the mud foot exceeds the standard, you can only use a hand-held transplanter or a floating boat.

3. Viscosity of soil

The power consumption of rice transplanter is affected by soil quality to a certain extent. The sandy soil settles well and the walking load of the transplanter is low; the adhesion of clay to the machine chassis makes the walking load larger, which will directly affect the efficiency and induce machine failure.

Suggestion: in the rice field with high soil viscosity, when using the passenger transplanter, we need to consider the use of high-power mechanical engine.

4. Rational allocation of balancing device for transplanting table

The transplanting quality is the depth of transplanting to a certain extent, and stable and shallow planting is the guarantee of transplanting quality. When the transplanter is walking, it is affected by the leveling of the field and the depth of the mud foot, and the jitter of the left and right fluctuation of the planting table is easy to cause uneven depth of the left and right transplanting seedlings and affect the quality of the operation. Among the types of seedling platform balancing devices of rice transplanter, there are three ways: mechanical balance, electric balance and electro-hydraulic balance, and their price and effect are different.

Mechanical balance: the shaking in the operation of the seedling platform tends to be stable by balancing the action of the spring and the bottom floating boat. This is a passive balancing device, and it is also a conventional standard configuration of high-speed rice transplanter.

Electric balance: on the basis of mechanical balance, the driving motor is controlled by the signal, and the motor pulls the balance spring to make the seedling platform adjust the balance quickly during the period of large jitter, which is the active balancing device of high-speed rice transplanter.

Electronic hydraulic balance: the computer chip memorizes the balance position, formulates the electronic signal according to the tilt angle of the seedling table, gives the hydraulic solenoid valve to control the action of the hydraulic cylinder, and locks the balance position of the seedling table, which is the most sensitive way to control the balance of the high-speed rice transplanter.

It is suggested that among the three kinds of balancing devices, reasonable purchase and configuration should be made according to the conditions of purchasing land, mud base and mud surface after rotating the field.

III. Basic vaccine requirements

There is a big difference in the amount of rice seedlings taken by the rice transplanter. At present, most of the row spacing of the high-speed seated transplanter on the market is 30 cm, the plant spacing is 12rel 28 cm, and the basic seedling is 120000-315000 holes per hectare. According to the specific needs of close planting, some manufacturers have also developed a transplanter with a row spacing of 25 cm, a plant spacing of 10 mi 22 cm and a basic seedling of 180000-378000 holes per hectare, which is also the main push machine in the double-cropping rice area of Hunan Province.

Suggestion: each region has its own requirements on the basic seedlings of mechanical transplanting according to the agronomic characteristics, and choose the parameters of the transplanter to adapt to their own needs, especially in the requirements of basic seedlings, when selecting and purchasing the transplanter, we should have a detailed understanding of the instructions of the machine.

IV. Calculation of investment income

In line with the above conditions of use, the performance-to-price ratio of the rice transplanter should be considered. The performance-to-price ratio is shown in product efficacy, purchase price and use cost, from which the payback period of investment is calculated.

(1) the efficacy of the product is function and efficiency. The basic configuration to ensure the quality of machine insertion operation is the premise of purchase, and operation efficiency is the key to generating income.

(2) the price of the whole machine, the price of spare parts and the durability of spare parts. The price of the whole machine is clearly stated at the time of purchase, but it is very important to compare the cost of key components, so it is necessary to check the list of random accessories and instructions, the price of consumables, the reference time for the replacement of vulnerable parts and other items to compare.

Suggestion: the price of the whole machine is basically clear, and the spare parts price and replacement cycle can be understood by referring to the "product instructions" and the list of random accessories.

V. Service guarantee

In the selection and purchase of models, users need to inspect the service capabilities of the seller, such as service personnel, spare parts inventory, tools and vehicles. At the same time, confirm the service commitment given by the manufacturer, such as delivery mode, user training, busy agricultural service and post-season maintenance, etc.

Suggestion: machine buyers try to choose well-known brand machines, so that after-sales service is more guaranteed. Brand products have strict requirements on users' pre-sale, in-sale and after-sales service, and the service commitment should be confirmed in detail when purchasing the machine. The specific implementation of service guarantee is the number and qualification certification of technical personnel, the quantity and variety of spare parts inventory, the number of agricultural busy service vehicles, the service telephone number, etc., and the service guarantee matters should be agreed upon in advance before the purchase of the machine.

To sum up, with the increase of national subsidies for the purchase of agricultural machinery and the improvement of farmers' purchasing power, the key link of rice production mechanization, "machine transplanting", has been gradually accepted by farmers. The selection and purchase of rice production machinery with complete functions, strong adaptability and high performance-to-price ratio has become a project of common concern to agricultural machinery management departments and farmers. All kinds of specifications of rice transplanter are designed and produced according to the requirements of specific use conditions, which is the result of the combination of agronomy and agricultural machinery. Due to the influence of origin, quality and functional configuration, the price of products varies greatly. Now, everyone knows how to choose a rice transplanter.
