Sliding-raising mechanism of ditcher

Abstract

The invention discloses a sliding and warping mechanism of a ditching machine, which comprises a closed sleeve or a sliding clamp and a sliding warp arranged at the front end of the frame arm of the trenching machine. One side of the closed casing is provided with a bolt hole, and the sliding warping The sliding column is provided with multiple bolt holes, and its characteristic is: there is also a U-shaped joint block, and the two vertical columns of the U-shaped joint block are provided with bolt holes; the sliding column can be directly fixed on the closed type with bolts. On the sleeve pipe or the sliding clip, the U-shaped joint block can also be fixed on the closed sleeve pipe or the sliding clip with bolts, and then the sliding post can be fixed on another vertical column of the U-shaped joint block with bolts. The mechanism of the invention can not only adapt to opening new ditches in ordinary fields, but also solves the problem of repeated ditching, widening and deepening in old ditches.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and relates to a sliding and warping mechanism of a farmland ditching machine which can adapt to repeated ditching in old ditches. Background technique [0002] The Chinese utility model patent "Front Ditcher" (authorized announcement number: CN2375068Y, patent number: 99228497) discloses a single cantilever type farmland ditcher, which has been widely used now. The frame arm is a single cantilever structure, and there is a closed casing at the front, and the sliding column for adjusting the depth runs through the casing, and is tightened with a set bolt, and the sliding is just below the frame arm. [0003] In many areas, no-till farming is adopted in the farmland. After crops such as wheat and rapeseed are harvested, the land is no longer plowed, but the next round of crops is planted using no-till. Therefore, the ditches opened in the wheat fields of the previous year still exist, but Du...

AI Technical Summary

Problems solved by technology

However, because the sliding warp of the existing trencher is below the frame arm and close to the cutter head of the trencher, when this trencher is used to repeatedly ditch the old ditch, it will be close to the old trench due to the slippery warp. The edge, if you don’t pay attention, it will slip into the old ditch due to the slope of the edge of the old ditch. After sliding into the old ditch, the bottom of the ditch will suddenly become deeper, and the speed of the diesel engine will decrease due to the sudden increase of the ditching load. even turn off

On the other hand, there is only one screw on the side of the existing bushing to fasten the sliding post instead of passing through the sliding post. The tightening force is not enough, and the sliding post will slip off after loosening
