[0029] As Figures 1 - 4 shown;

[0030] A three-element separation device for straw, comprising a device body 1 and a housing 4 sleeved on the outer surface of the device body 1.

[0031] In this implementation: It is found that the publication (announcement) number: CN211772388U discloses a three-element separation device for wheat straw, and this technology discloses "a three-element separation device for wheat straw, including an input pipeline and a separation tank. The outlet end of the input pipeline is connected to the lower part of the separation tank. A spiral upward rotating groove is provided on the inner straight wall of the separation tank, and a number of twisting bumps are integrally provided in the rotating groove. The outlet end of the input pipeline is provided with a baffle on the side away from the bottom of the rotating groove and other technical contents, and discloses that this three-element separation device for wheat straw can transport the wheat straw particles after high-temperature and high-pressure cooking to the separation tank through the input pipeline. During the high-pressure spraying process, the wheat straw particles move quickly upward along the rotating groove and the bumps therein along the rotating groove. At the same time, the wheat straw particles in the groove are subjected to the friction and twisting of the bumps, and the wheat straw particles in the groove will all move upward in a spiral manner, achieving the preliminary three-element separation of wheat straw and other technical effects";

[0032] When the existing straw three-element separation device is in use, when transporting straw particles, it is easy to cause blockage of the straw particles in the three-element separation device. Since the pipeline in the three-element separation device is spiral, it is very inconvenient to dredge and clean after blockage. Considering the actual use, this problem is obviously a real and difficult problem to solve. In view of this, to solve this technical problem, a vibration component 2 and a temporary fixing component 3 are added in this application document.

The toothed disc 203 meshes with the small gear 202. A plurality of wedge-shaped blocks 204 are equidistantly installed on the top surface of the toothed disc 203. A top block 205 abuts against the wedge-shaped blocks 204. The top block 205 is installed on the bottom surface of the device body 1. A corrugated pipe is installed at the feed port of the device body 1, and the corrugated pipe is communicated with the feed pipe of the housing 4. A second corrugated pipe 209 is installed at the discharge end of the device body 1, and the second corrugated pipe 209 is communicated with the flange of the housing 4. The bottom surface of the toothed disc 203 is rotatably connected with a limit disc 210, and the limit disc 210 is installed on the inner wall of the housing 4.

[0034] In this embodiment: When separating the three elements of the straw, the motor 201 on the housing 4 drives the toothed disc 203 to rotate in the housing 4 through the small gear 202. The toothed disc 203 rotates on the limit disc 210 in the housing 4, and the wedge-shaped blocks 204 on the toothed disc 203 push the top block 205, so that the top block 205 can lift the device body 1. The device body 1 will not stop conveying during the vibration process. Through the first corrugated pipe 206, the straw particles can be continuously conveyed, and the second corrugated pipe 209 at the other end of the device body 1 conveys the straw particles out. During the conveying process, blockage of the straw particles will not occur, the particle conveying efficiency is improved, and blockage during the conveying process of the straw particles is avoided.

[0035] In an alternative embodiment: A plurality of U-shaped guide bars 207 are equidistantly installed on the inner wall of the housing 4.

[0036] In this embodiment: The device body 1 is limited by the limit bars. The tension spring 208 in the limit bars can reduce the descending speed of the main body through the tension spring 208 when the device body 1 descends, and reduce the generation of vibration.

[0037] In an alternative embodiment: A buffer rubber block 211 is installed at the center of the inner ground of the housing 4, and the top surface of the buffer rubber block 211 abuts against the bottom of the device body 1.

A bolt 304 is screwed inside the shaft rod 302, and a crank 305 is installed at one end of each of the two bolts 304 away from each other.

[0042] In this implementation scheme: When installing the device body 1, the external pipeline is docked with the flange on the outer shell 4. Then, the snap ring 301 is rotated by the support rod 303, so that the snap ring 301 presses on the external pipeline by gravity. Then, the two cranks 305 are rotated respectively, so that the cranks 305 drive the bolts 304 to move inside the shaft rods 302 on the outer shell 4, and the support rod 303 is fixed by the anti-slip lines on the cranks 305.

[0043] In an optional embodiment: The snap ring 301 is arranged in an arc shape, and an arc-shaped groove is provided on the surface of the snap ring 301.

[0044] In this embodiment: The arc-shaped groove provided on the surface of the snap ring 301 is at a position corresponding to the flange mounting hole of the outer shell 4 and is larger than the diameter of the bolt 304.

[0045] Working principle and usage process of the utility model: When separating the three elements of straw, the motor 201 on the outer shell 4 drives the toothed disc 203 to rotate in the outer shell 4 through the small gear 202. The toothed disc 203 rotates on the limiting disc 210 in the outer shell 4, and the wedge-shaped block 204 on the toothed disc 203 pushes the top block 205, enabling the top block 205 to lift the device body 1. The device body 1 will not stop conveying during the vibration process. The straw particles can continue to be conveyed through the first corrugated pipe 206, and the second corrugated pipe 209 at the other end of the device body 1 conveys the straw particles out. During the conveying process, the straw particles will not be blocked, improving the particle conveying efficiency and avoiding the situation of blockage during the straw particle conveying process. The device body 1 is limited by the limiting strip, and the tension spring 208 in the limiting strip can reduce the descending speed of the main body through the tension spring 208 when the device body 1 descends, reducing the generation of vibration. The buffer rubber block 211 in the outer shell 4 can avoid the impact between the device body 1 and the outer shell 4, reducing the vibration feeling. Then, when installing the device body 1, the external pipeline is docked with the flange on the outer shell 4. Then, the support rod 303 rotates the clamping ring 301, enabling the clamping ring 301 to press on the external pipeline under the action of gravity. Then, the two cranks 305 are rotated respectively, enabling the crank 305 to drive the bolt 304 to move in the shaft rod 302 on the outer shell 4, and fixing the support rod 303 through the anti-slip pattern on the crank 305. The arc-shaped groove opened on the surface of the clamping ring 301 is at the position corresponding to the flange mounting hole of the outer shell 4 and is larger than the diameter of the bolt 304.
