Problems solved by technology

This kind of live broadcast machine cannot adapt well to the natural environment of the Tibetan grassland in production operations
The grasslands in Tibet have unique conditions. The development of the grassland is very low, the soil layer is thin but extremely hard, and there are a lot of rocks on the surface and in the soil. The ditching device of the above-mentioned live broadcast machine cannot make a deep enough trench, so that the sown pasture survives. The rate is low, which affects the sowing operation

Embodiment Construction

[0017] Such as figure 1 , figure 2 As shown, the opener of the present invention includes a cutterhead shaft 10, a circular disk body 22 and cutter teeth 23, wherein the three circular disk bodies 22 are fixedly mounted on the cutterhead shaft 10 through a central hole. There can also be one or two or more circular disc bodies 22 .

[0018] Each circular disk body 22 includes ten positioning steps 24 protruding from the surface of the disk body, and the ten positioning steps 24 enclose a regular decagonal boss 25 concentric with the circular disk body.

[0019] The ten cutter teeth 23 are respectively installed on the circular disk body 22 by bolts. The ten positioning steps 24 are respectively used to fix and limit the ten cutter teeth 23 .

[0020] combine image 3 As shown, the cutter tooth 23 includes a working portion 231 and a fixed connection portion 232 . The working part 231 and the fixed connection part 232 are integrally structured. The working part 231 is ro...

Abstract

The invention relates to a ditching device, comprising a circular disc, a cutter shaft and cutter teeth, wherein, the circular disc is fixed on the cutter shaft and is equipped with locating steps protruding the surface of the circular disc; the locating steps are enclosed into a boss which is concentric with the circular disc; the cutter teeth are arranged on the circular disc; and the locating steps are used for fixing and limiting the cutter teeth. The ditching device has the advantages that while a seeding machine works, the circular disc of the ditching device rotates, and the cutter teeth cut into soil alternately; and the pressure borne by the circular disc is completely concentrated on the tip part of the cutter teeth, thus more powerfully and conveniently cutting soil and being especially suitable for no-tillage ditching on hard soil.

Description

technical field [0001] The invention relates to a component of an agricultural combined operation machine, in particular to a ditch opener. Background technique [0002] The degradation and desertification of arid and semi-arid grasslands in my country are very serious, and have become ecological and environmental problems that must be solved by taking necessary measures. Taking the grasslands of Tibet as an example, there are 364 million mu of degraded grasslands in the region, accounting for 42% of the usable area In recent years, a lot of work has been done in improving the alpine grassland and re-seeding pasture in Tibet, but the progress is slow because of the lack of suitable grass-seeding machinery. Because the soil layer of the degraded grassland is very thin, it is not suitable to adopt the traditional plowing method for sowing. The Chinese invention patent with the publication number CN 2781735Y discloses a direct seeding machine that adopts the rotary tillage metho...
