hay cutter

Abstract

The invention relates to an agricultural machine, in particular to a hay cutter which adopts the joint operation of a cutting knife and a crushing knife, comprising a base, a feeding mechanism, an upper cover, a speed change mechanism and a main shaft assembly, and a drive The power source for the rotation of the main shaft assembly, the main shaft assembly is provided with a cutter head assembly with wind blades, the main shaft assembly is connected with the feeding mechanism through a transmission mechanism, and the cutter head assembly includes a knife Disc, cutting knife layer and crushing knife layer, wherein the cutting knife layer composed of multiple cutting knives is set on the side of the cutter head close to the feeding mechanism, and the crushing knife layer composed of multiple crushing knives is set on the cutter head away from the feeding mechanism On one side, the speed change mechanism includes a case body, a shift transmission mechanism and a handle assembly. The shift transmission mechanism is arranged in the case body and adjusts gears through the handle assembly arranged on the upper side of the case body. The invention greatly improves the feed processing fineness and feed processing efficiency, and at the same time can realize the diversification of feed processing.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a hay cutter which adopts the combined operation of a cutting knife and a crushing knife. Background technique [0002] With the development of animal husbandry, animal husbandry has higher and higher requirements for forage processing quality. Commonly used forage processing equipment mainly includes hay cutters and pulverizers, of which the hay cutters in the prior art are only It can cut crops such as grass or straw into small pieces, but cannot further crush each small piece, so the fineness of the processed forage is poor, and the livestock are unwilling to eat it. Usually, follow-up processing is required to improve the fineness of the feed. This not only wastes manpower and material resources, but also greatly reduces the feed processing efficiency. In addition, although there is a speed change mechanism in the prior art hay cutter, the speed change mechanism is only used to redu...

[0002] With the development of animal husbandry, animal husbandry has higher and higher requirements for forage processing quality. Commonly used forage processing equipment mainly includes hay cutters and pulverizers, of which the hay cutters in the prior art are only It can cut crops such as grass or straw into small pieces, but cannot further crush each small piece, so the fineness of the processed forage is poor, and the livestock are unwilling to eat it. Usually, follow-up processing is required to improve the fineness of the feed. This not only wastes manpower and material resources, but also greatly reduces the feed processing efficiency. In addition, although there is a speed change mechanism in the prior art hay cutter, the speed change mechanism is only used to reduce the input speed, and cannot accurately set the rotation speed gear.
