Description

Technical Field

[0001] This utility model relates to the technical field of straw processing equipment, specifically a straw crushing and returning equipment. Background Technology

[0002] Returning straw to the field has many advantages, such as improving soil structure, increasing soil organic matter, improving soil fertility, and eliminating air pollution caused by straw burning. It has gradually become popular and has generated good economic, ecological and social benefits.

[0003] Currently used straw crushing and returning equipment mostly relies on a single roller for transmission. This method has poor conveying efficiency, which easily leads to material accumulation during use, affecting subsequent use. At the same time, most of these devices use a single fixed blade or straight blade for cutting, resulting in incomplete cutting of the straw and reducing the crushing effect of the device.

[0004] In summary, this utility model solves the problems in the background art by designing a straw crushing and returning equipment. Utility Model Content

[0027] For examples, please refer to Figure 1-5 This utility model provides a technical solution:

[0028] A straw crushing and returning-to-field processing device includes a processing box 1 and a conveying box 2 set at the bottom of the processing box 1. The processing box 1 has a processing chamber 3 inside, and the processing chamber 3 is respectively equipped with a crushing shaft 301, a straight blade 302 and a screen 303. A fixed blade 3011 is fixedly installed on the outside of the crushing shaft 301. A crushing motor 4 is fixedly installed on the rear side of the processing box 1. A hopper 201 is set on the top of the conveying box 2, and a discharge port 202 is opened on the right side surface of the conveying box 2.

[0029] Specifically, the crushing shaft 301 is rotatably connected to the inner walls of the front and rear ends of the processing chamber 3 through a sealed bearing. The output end of the crushing motor 4 passes through the rear surface of the processing box 1 and is fixed to the rear end of the crushing shaft 301. The outer surface of the fixed blade 3011 is provided with a serrated blade edge. The fixed blades 3011 are distributed in a ring at equal intervals about the outer surface of the crushing shaft 301. The straight blade 302 is staggered with the fixed blade 3011 in a stable manner.

[0030] In this embodiment, the crushing motor 4 is mainly used to drive the crushing shaft 301, which in turn drives the fixed blade 3011 to rotate, resulting in staggered shearing between the fixed blade 3011 and the straight blade 302. With the cooperation of the serrated blade edge, the crushing effect of straw is improved.

[0031] Specifically, the screen 303 is embedded in the bottom inner wall of the processing chamber 3, the bottom of the screen 303 extends to the bottom surface of the processing box 1, the top surface of the hopper 201 is in fixed contact with the bottom surface of the processing box 1, and the hopper 201 completely covers the bottom of the screen 303, and the bottom inner wall of the hopper 201 extends into the interior of the conveying box 2.

[0032] In this embodiment, the screen 303 is mainly used to screen out the crushed straw, so that the screened straw enters the inside of the conveyor box 2 through the hopper 201.

[0033] In this embodiment, please refer to Figure 1 , Figure 4 and Figure 5 A conveyor motor 203 is fixedly installed on the rear side of the conveyor box 2. Inside the conveyor box 2, a first conveyor roller 204, a second conveyor roller 205 and a drum 206 are respectively rotatably arranged. A conveyor belt 207 is sleeved on the outer surface of the first conveyor roller 204 and the second conveyor roller 205.

[0034] Specifically, the output end of the conveyor motor 203 passes through the rear surface of the conveyor box 2 and is fixedly connected to the rear end of the first conveyor roller 204. The rollers 206 are distributed equidistantly on the left and right sides of the inner wall of the conveyor box 2, and the outer top of the rollers 206 rolls in contact with the inner side of the conveyor belt 207.

[0035] In this embodiment, the conveyor motor 203 is mainly used to drive the first conveyor roller 204. With the combination of the first conveyor roller 204 and the second conveyor roller 205, the displacement transmission of the conveyor belt 207 can be realized. The roller 206 is mainly used to support the conveyor belt 207, ensuring the conveying efficiency of the device.

[0036] The working process of this utility model is as follows: When using a straw crushing and returning-to-field treatment device, straw is fed into the treatment chamber 3, and the crushing motor 4 is started. The crushing motor 4 drives the crushing shaft 301 to rotate, and the crushing shaft 301 drives the fixed blade 3011 to rotate. The fixed blade 3011 and the straight blade 302 form a shearing action, cutting the straw into fragments. The crushed straw enters the discharge hopper 201 through the screen 303 and falls along the inner wall of the discharge hopper 201 into the interior of the conveying box 2. When the conveyor motor 203 is started, its output drives the first conveyor roller 204 to rotate. With the cooperation of the first conveyor roller 204 and the second conveyor roller 205, the conveyor belt 207 is driven to run, causing the conveyor belt 207 to move the debris to the discharge port 202. During the movement, the roller 206 rolls and contacts the inner wall of the conveyor belt 207, ensuring the conveying effect of the conveyor belt 207, so that the debris is scattered from the discharge port 202 into the field, meeting the needs of the users.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
