Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of straw processing, in particular to a straw chopping device. Background Art
[0002] Chinese farmers have a long history of using crop straw. In the past, agricultural production levels were low, yields were low, and the amount of straw was small. Except for a small amount used for bedding and feeding livestock, and some used for composting, most of the straw was burned as fuel. With the development of agricultural production, the increase in grain output has led to an increase in the amount of straw. In addition, the promotion of firewood and coal saving technologies, the popularization of coal burning and the use of liquefied gas have resulted in a large amount of surplus straw in rural areas. Whether the surplus straw is used as feed or for other purposes, it needs to be crushed first.
[0003] The chopping equipment in the prior art does not have the function of removing gravel and mud mixed in the straw. Usually, the bundled straw is spread out and placed directly in a hay chopper for chopping. Since gravel and mud are mixed in the straw when it is bundled, the gravel will damage the cutters in the hay chopper when it is chopped, and the mud will affect the taste of the straw feed for animals. In addition, if you want to remove the gravel and mud mixed in the straw, you need to remove them manually, which is labor-intensive and affects the chopping efficiency. In view of this, a straw chopping device is proposed to solve the above problems. Utility Model Content

[0006] The material shaking mechanism includes a support column and a motor. The motor is fixedly installed in the support frame. A turntable is fixed at the output end of the motor. A fixed column is fixed at the eccentric part of the turntable. A first hinged rod is rotatably installed on the fixed column. One end of the first hinged rod is hinged to a second hinged rod.
[0007] A support column is fixed at the bottom of the inner cavity of the support frame, a sliding sleeve is slidably installed on the support column, one side of the sliding sleeve is fixed to the other end of the second hinged rod, a cross plate is fixed on the outside of the sliding sleeve, a plurality of fixed rods are fixed on the cross plate, and a material shaking rod is fixed at one end of the fixed rod.
[0008] Furthermore, the material shaking rod is located between every two rotating rollers, and the diameter of the material shaking rod is smaller than the diameter of the conveying roller.
[0009] Furthermore, a sliding rail is arranged on the support column, and a sliding groove which is slidably matched with the sliding rail is provided on the sliding sleeve.
[0010] Furthermore, a top plate is fixed to the top of the support column, and the horizontal plate is high in the middle and low around.
[0011] Furthermore, a discharge port is provided at the lower end of the support frame, and a collection box for collecting stones dropped from the discharge port is placed below the support frame.
