AI Technical Summary
When cutting crops with existing green feed harvesters, the crops are prone to fly out along the tangent line, resulting in some crops not being able to fall on the conveying mechanism of the harvester, poor aggregation and manual picking is required, which increases labor intensity.
A green feed harvester chopping roller is designed. The chopping knife is arranged in a herringbone shape and is arranged in an inclined manner, fixed on the outer side of the chopping roller shaft to ensure that the crops gather inward during cutting and fall on the conveying mechanism.
Through the herringbone-shaped staggered chopping knife design, the crops gather inward during cutting, avoid divergence and flying out, improve harvesting performance and reduce the labor burden of farmers.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of green fodder harvesters, in particular to a chopping drum of a green fodder harvester. Background Art
[0002] A green fodder harvester is an agricultural machinery device mainly used to harvest low green fodder crops such as green grass, oats, and beet stems and leaves. The most important part of the harvester is the chopping drum.
[0003] The crops are cut by setting a cutter on the shredder drum. At present, the cutter on the shredder drum is basically an integrated knife. When the crops are cut, the crops will fly out along the tangent line under the action of rotation, so that some crops cannot fall on the conveying mechanism of the harvester, and the aggregation is poor. It is also necessary to manually pick up the thrown crops, which increases the labor intensity of farmers. Summary of the invention
[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a green fodder harvester chopping drum, which can gather crops and drop them on a conveying mechanism when cutting them, prevent the crops from scattering and flying out, facilitate collection, and effectively solve the problems in the background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a green fodder harvester chopping drum, comprising a chopping drum shaft, two fixed width disks are symmetrically arranged at both ends of the outer side surface of the chopping drum shaft, a chopping knife is fixed on one side of each fixed width disk, the chopping knife is inclined, and the chopping knives on the two fixed width disks are staggeredly distributed in a herringbone shape.
[0006] As a preferred technical solution of the utility model, the inclination angle of the chopping knife is 8 to 10 degrees.
[0007] As a preferred technical solution of the utility model, an intermediate width disk is arranged between the two fixed width disks, the intermediate width disk is fixed to the outer side surface of the shredding drum shaft, and the other end of the shredding knife is connected to the intermediate width disk.
[0008] As a preferred technical solution of the utility model, a reinforcing rib is fixed on one end of the chopping knife close to the fixed width disc.
[0009] As a preferred technical solution of the utility model, twelve chopping knives are arranged on the outer side of the fixed width disk, and the twelve chopping knives are evenly distributed on the outer side of the fixed width disk.
[0010] Compared with the prior art, the beneficial effects of the utility model are as follows: the chopping drum of the green fodder harvester has a compact structure, a reasonable design, and is easy to operate. The chopping knives are staggered in a herringbone shape and gaps are left between adjacent chopping knives, so that the crops are gathered inward while being chopped, ensuring that the chopped crops fall on the conveying mechanism, avoiding the situation where the crops are scattered and thrown out, which not only improves the harvesting performance of the harvester, but also reduces the labor burden of farmers. BRIEF DESCRIPTION OF THE DRAWINGS
[0011] Figure 1 It is a schematic diagram of the structure of the utility model;
[0012] Figure 2 It is the front view of the utility model.
[0013] In the figure: 1 shredding drum shaft, 2 fixed width disc, 3 reinforcing ribs, 4 shredding knife, 5 middle width disc. DETAILED DESCRIPTION
[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0015] See also Figure 1-2 The utility model provides a technical solution: a chopping drum of a green fodder harvester, comprising a chopping drum shaft 1, two fixed width discs 2 are symmetrically arranged at both ends of the outer side surface of the chopping drum shaft 1, a chopping knife 4 is fixed on one side of each fixed width disc 2, and the chopping knife 4 is fixed on one side of the fixed width disc 2 at an angle of 8.8°, so that the chopping knives 4 on the two fixed width discs 2 are staggered inwardly in a herringbone shape, and while chopping crops, they are gathered inward and fall on the conveying mechanism to avoid being thrown out in a divergent manner, thereby ensuring the harvest quality.
[0016] Furthermore, an intermediate width disc 5 is provided between the two fixed width discs 2. The intermediate width disc 5 is fixed to the outer side of the shredding drum shaft 1. The other end of the shredding knife 4 is connected to the intermediate width disc 5. The stability of the shredding knife 4 is improved by providing the intermediate width disc 5.
[0017] Furthermore, a reinforcing rib 3 is fixed to one end of the chopping knife 4 close to the fixed width plate 2, and the reinforcing rib 3 can play a protective role to prevent crops from being thrown out.
[0018] Furthermore, twelve chopping knives 4 are arranged on the outer side of the fixed width disc 2 . The twelve chopping knives 4 are evenly distributed on the outer side of the fixed width disc 2 , so that the chopping performance of the chopping knives 4 can be ensured.
[0019] When in use: the chopping drum shaft is installed at the front end of the harvester and connected to the drive motor. During the harvesting operation, the crops are chopped by the high rotation of the chopping knife. At the same time, because the chopping knife is staggered and tilted inward in a herringbone shape, the crops are gathered inward while being chopped, so that the chopped crops can fall onto the conveying mechanism.
[0020] The utility model can make the crops gather inwards while being chopped and fall onto the conveying mechanism under the premise of ensuring the chopping performance, thus avoiding the crops from being scattered, reducing the labor load of farmers and improving the convenience of use.
[0021] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
