Automatic cutter grinding device of silage maize harvester and silage maize harvester automatically grinding cutters

Abstract

The invention discloses an automatic cutter grinding device of a silage maize harvester and the silage maize harvester automatically grinding cutters. The automatic cutter grinding device is installed above chopping rollers of the silage maize harvester and acts on the movable cutters on the chopping rollers. The automatic cutter grinding device comprises a horizontal transmission device, a cutter grinding stone sleeve, a cutter grinding stone, a sliding block, a guide rail and guide rail fixing blocks. One end of the horizontal transmission device and one end of the guide rail are fixed to a left side plate, and the other end of the horizontal transmission device and the other end of the guide rail are fixed to a right side plate. The part, at the upper portion of the cutter grinding stone sleeve, of the horizontal transmission device is connected with the sliding block on the guide rail. The horizontal transmission device drives the cutter grinding stone of the cutter grinding stone sleeve to horizontally reciprocate. The automatic cutter grinding device is simple and ingenious in structural design, the manufacturing difficulty is lowered, the manufacturing cost is reduced, flexible control is easy to achieve, and the work efficiency and stability are improved.

Description

technical field [0001] The invention relates to an automatic knife sharpening device for a silage machine and an automatic knife sharpening silage machine, belonging to the technical field of modern agricultural machinery. Background technique [0002] Corn stalks have high utilization value. In recent years, with the rapid development of animal husbandry, the problem of animal feed shortage has become increasingly serious, especially in winter. In the rural areas of our country, corn stalks have a long history as animal feed, but corn stalks are mostly harvested manually, which is labor-intensive. Sometimes in order to rush to plant winter wheat, farmers often burn straws on the spot after harvesting corn ears, which not only destroys the organic matter and microorganisms in the soil, causes soil compaction and soil fertility, but also wastes a lot of straw resources. [0003] The mechanization of silage corn harvesting is an important measure to improve the feed quality ...

AI Technical Summary

Problems solved by technology

Because manual sharpening is less efficient than automatic sharpening, and requires human participation, the efficiency is low. However, the entire structure and control system of foreign automatic sharpening are complicated, and the manufacturing process is more difficult and the cost is higher.

Looking at domestic silage machines, the knife sharpening is still done when the operation is greatly affected or after a working season. The efficiency is very low.
