Tillage equipment

Abstract

The present invention relates to a tillage machine, including machine frame, knife roller formed from knife roller shaft and knife disk, stubble-breaking knife and rotary tilling knife. The improvement lies in that a speed-change box with two rotating speed outputs is added. On the knife disk the stubble-breaking knife mounting hole and rotary tilling knife mounting hole are set, on the knife handle of the rotary tilling knife two mounting holes are set. When it is used for making stubble-breaking operation, the stubble-breaking knife is mounted on the knife disk, and when it is used for making rotary tilling operation, the rotary tilling knife is mounted on the knife disk.

Description

technical field [0001] The invention belongs to agricultural soil preparation machinery. Background technique [0002] In the current farming method, before a new round of sowing, plowing is carried out, and stubble breaking and rotary tillage are mostly carried out. For these two kinds of tillage operations, there are already stubble breakers and rotary tillers. Both the stubble breaker and the rotary tiller in the prior art include a frame, a reduction gear box and a knife roller and the like. In the existing stubble breaker, the cutterheads of the stubble cutters are installed in four groups and welded on a section of square pipe with a spacing of 80mm, and then the four groups of cutterheads are put on the square pipe cutter rollers to locate and fix. The working width of the stubble cutter is 80mm. The first problem with this installation method of the cutterhead is that the stubble cutters are arranged in a multi-head helical line on the four cutterheads in one group,...

AI Technical Summary

Problems solved by technology

There are only two knives on each rotary surface, and the soil-cutting pitch of the rotary tiller is guaranteed by the number of revolutions. When the forward speed of the machine remains constant, at the same rotational speed of the cutter roller, if you want to reduce the soil-cutting pitch, you need to Increase the number of knives. However, in this form of installing rotary tillage knives with knife holders, when the number of knife holders on one rotary surface exceeds two, it will cause soil and grass entanglement, which will have a negative impact on rotary tillage.

The distance between knife seats is relatively narrow, generally 85mm, and the number of knife seats welded on the entire knife roll is relatively large, and the welding process is more complicated
