Automatic sharpening device for silage harvester

Abstract

The invention provides an automatic knife sharpening device for a silage harvester, which is characterized in that it includes a reciprocating mechanism and a knife sharpening feeding mechanism; wherein the reciprocating mechanism includes a guide rail base, two guide rails horizontally installed on the guide rail base, A pair of sliders installed on the two guide rails, a slider plate that fixes the pair of sliders together, a lead screw, a lead screw support, a lead screw nut, a motor and a pawl; the sharpening mechanism includes a grinding Knife housing, knife grinding wheel, worm wheel, worm, shaft, feed sleeve, ratchet wheel; knife grinding feeding mechanism is connected with the slider plate of the reciprocating mechanism through the knife grinding housing. Before grinding the knife, adjust the grinding wheel to be in contact with the moving knife of the hob-type chopper. When grinding the knife, the grinding wheel is driven by the motor to reciprocate by the screw nut, thereby resetting the cutting edge of the moving knife on the drum. sharpen. The structural design is simple and practical, reduces manufacturing difficulty and cost, is easy to operate and control, and improves work efficiency and work quality.

Description

Technical field [0001] The patent of the invention belongs to the field of agricultural machinery, and specifically is an automatic knife sharpening device for a silage harvester, which is suitable for use with a hob-type chopper of the silage harvester. technical background [0002] With the rapid development of animal husbandry and the adjustment of corn planting structure, straw harvesting such as corn silage harvesting or both ear and straw harvesting has been rapidly developed, so silage corn harvesters are widely used. However, when the effect of the machine reaches a certain level, the movable blade on the shredding hob of the straw shredding device will experience varying degrees of wear, resulting in poor shredding quality and high power consumption, requiring sharpening. Since there are multiple moving knives on the shredding hob of the straw shredding device, if the moving knives are sharpened piece by piece, not only is the efficiency low, it is also difficult to ensu...

AI Technical Summary

Problems solved by technology

However, when the effect of the machine reaches a certain level, the moving knife blade on the hob of the straw chopping device will be worn to varying degrees, resulting in poor chopping quality and high power consumption, requiring sharpening.

Since there are many moving knives on the chopping hob of the straw chopping device, if the moving knives are sharpened one by one, not only the efficiency is low, but also it is difficult to ensure the dynamic balance of the chopping hob

[0003] At present, foreign silage harvesters have matching automatic sharpening systems or manual sharpening devices. Manual sharpening is less efficient than automatic sharpening. Some domestic models have matching manual sharpening devices, which are less efficient.

The structure and control system of the automatic sharpening system of foreign silage harvesters are complex and costly
