Refitting course of ordinary rotary tiller

Rotary tiller is a kind of ploughing machine matched with tractor to complete ploughing and raking operation. it has been widely used because of its strong ability to crush soil and flat surface after ploughing. At the same time, it can cut up the stubble buried below the surface to facilitate the operation of the planter and provide a good seed bed for later sowing. It is often necessary to refit the rotary tiller in agricultural production. Here are some specific tutorials on how to convert the ordinary rotary tiller into a high stubble returning machine.

The main difference between the ordinary rotary tiller and the rice high stubble returning machine is that the blade on the knife shaft is different. To convert it into a high stubble field preparation machine, just replace the knife shaft with the blade.

The knife shaft of the ordinary rotary tiller is also fixed on the end panel of the frame through the bearing cover at the outer end of the frame. Unscrew the screw on the bearing cover, unscrew the connecting screw between the end panel and the main beam and the auxiliary beam, remove two end panels, the inner end of the rotary tiller cutter shaft is also connected with the gearbox through splines, pull out the opening pin and remove the positioning pin, while shaking the outer end of the cutter shaft, you can pull the knife shaft out of the gearbox. Then remove the other side of the knife shaft in the same way.

The frame of the rotary tiller is divided into the front beam and the rear beam, and the knife shaft of the rice high stubble returning machine, together with the stubble blade, is lifted to the middle of them, and the inner end of the knife shaft is placed on the output shaft spline of the gearbox. Insert the locating pin and lock the opening pin. If the length of the knife shaft of the rotary tiller and the rice high stubble returning machine is not the same, it is only necessary to lengthen the frame. Install the end panel at both ends, install the bearing cover at the outer end of the knife shaft on the end panel, and fix the end panel. The drag board also needs to be lengthened and then installed at the back of the rack. Also connect the long cover plate and install it on the top of the rack. This is how the modification work ends.

If farmers already have ploughing machines and know how to modify them, as long as they are equipped with a set of high stubble soil preparation machine spindles and stubble cutters, they can use both machines.

In the modification, some farmers want to increase the speed of the rotary tiller, is this feasible? When we purchase agricultural machinery and tools, distributors will recommend agricultural tools according to individual models, because the output speed varies with different horsepower. That is to say, during our purchase, the dealer has already matched the most reasonable configuration we need. If the individual wants to increase the speed privately, it is very simple to increase the speed. Just adjust the proportion of the umbrella wheel in the gearbox of the rotary tiller. However, if the damage to agricultural tools caused by private modification occurs, the manufacturer will not be held responsible. You have to think about that.

Another thing to note is, does the geographical environment of your homework allow you to modify it? For example, the structure of the land, whether the terrain is flat, the nature of the soil (black soil, red land, white land), etc., when the speed is too high, when the vehicle slows down or stops, when the rotary tiller is not lifted, there will be a big pit under the rotary tiller. And the object of the assignment is also a factor to be considered.
