[0019] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0020] 1. The utility model pours the straw on the top of the conveyor belt, and then drives the motor 1 to rotate the conveyor belt, so that the conveyor belt drives the straw to move.

[0030] Main frame 1;

[0031] A transmission mechanism, which is arranged inside the main frame 1;

[0032] A flattening mechanism is arranged at the top of the main frame 1, and the flattening mechanism includes a fixed box 4, the fixed box 4 is located at the top of the main frame 1, the rear end of the fixed box 4 is movably connected with a push rod 1 5, the rear end of the fixed box 4 is fixedly installed with a motor 2 6, the output end of the motor 2 6 is fixedly connected to the push rod 1 5, the front end of the fixed box 4 is movably connected with a push rod 2 23, the opposite side of the push rod 1 5 and the push rod 2 23 is hinged with a rotating shaft 7, and the surface of the rotating shaft 7 is fixedly installed with a fixed rod 8;

[0033] The crushing mechanism is arranged at the left end of the main frame 1.

[0034] The operator falls on the top of the transmission mechanism, and then drives the transmission mechanism to move the straw. During the movement, the motor 2 6 is used to rotate the push rod 5, so that the push rod 5 drives the rotating shaft 7 and the fixed rod 8 to move, so that the fixed rod 8 contacts with the transmission mechanism. During the contact with the transmission mechanism, there is a gap between the rotating shaft 7 and the transmission mechanism. Then the transmission mechanism acts as a power to fix the rod 8 and the rotating shaft 7 and rotate accordingly. Then the straw will pass through the gap between the rotating shaft 7 and the transmission mechanism. Because the gap between the rotating shaft 7 and the transmission mechanism is fixed, the thickness of the straw passing through the rotating shaft 7 is consistent. Then the straw will enter the crushing mechanism for crushing.

[0035] Wherein, the transmission mechanism includes a conveyor belt 2 and a motor 3;

[0036] The conveyor belt 2 is arranged inside the main frame 1, the motor 1 3 is fixedly connected to the front end of the main frame 1, and the output end of the motor 1 3 is fixedly connected to the conveyor belt 2.

[0037] Through the design of the transmission mechanism, the straw can be poured onto the top of the conveyor belt 2, and then the conveyor belt 2 is driven to rotate by the motor 3, and the rotation of the conveyor belt 2 drives the straw to move.

[0038] The crushing mechanism includes a crushing component 9 and a discharge port 10;

[0039] The crushing assembly 9 is fixedly connected to the left end of the main frame 1 , and the discharge port 10 is fixedly connected to the rear end of the crushing assembly 9 .

[0040] Through the inside of the pulverizing mechanism, straw with uniform thickness will enter the inside of the pulverizing component 9, and then the straw will be pulverized by the pulverizing component 9, and then the pulverized straw will be discharged from the discharge port 10.

[0041] The scraping mechanism is also provided at the bottom of the main frame 1, and includes a fixed box 12, a movable groove 13, a movable rod 14 and a scraper 15;

[0042] The fixed box 12 is fixedly connected to the bottom end of the main frame 1 , the movable groove 13 is opened at the front and rear ends of the fixed box 12 , the movable rod 14 is movably connected to the inside of the movable groove 13 , and the scraper 15 is fixedly connected to the opposite side of the movable rod 14 .

[0043] Through the design of the scraper mechanism, since the top of the scraper 15 is always in contact with the surface of the conveyor belt 2, the scraper 15 will always clean the surface of the conveyor belt 2 during the movement of the conveyor belt 2.

[0044] A support plate 11 is fixedly installed inside the main frame 1 , and the top end of the support plate 11 fits with the top end of the conveyor belt 2 .

[0045] The design of the support plate 11 can prevent the fixing rod 8 from sinking when it contacts the surface of the conveyor belt 2, thereby preventing the flattening work from being affected.

[0046] The device further includes: a pushing mechanism, which is arranged inside the fixing box 12 , and the pushing mechanism includes a fixing plate 16 , a spring assembly 17 , a motor 3 18 , a cam 19 and a tilting block 20 .

[0047] The fixed plate 16 is fixedly connected to the bottom end of the scraper 15, the spring assembly 17 is movably connected to the left end of the fixed plate 16, the motor three 18 is fixedly connected to the right end of the fixed box 12, the cam 19 is located at the output end of the motor three 18, and the tilting block 20 is fixedly connected to the top end of the fixed plate 16.

[0048] Through the design of the pushing mechanism, while the scraper 15 is performing the scraping work, the cam 19 is driven to rotate by the motor 3 18. During the rotation of the cam 19, it will contact the fixed plate 16, and then push the fixed plate 16 and the scraper 15 to move. During the movement of the fixed plate 16, the spring assembly 17 will be compressed. When the cam 19 is away from the surface of the fixed plate 16, the elastic force of the spring assembly 17 is used to restore the fixed plate 16, thereby realizing back and forth movement. The scraper 15 is driven to move back and forth through the fixed plate 16, thereby increasing the scraping effect.

[0049] A sewage outlet 21 is installed at the bottom end of the fixing box 12 , and a collecting box 22 is arranged at the bottom end of the sewage outlet 21 .

[0050] Through the design of the sewage outlet 21 and the collection box 22, after the scraper 15 scrapes off the mud, the mud will fall down, then pass through the sewage outlet 21 and enter the interior of the collection box 22, and the mud can be collected by the collection box 22.

[0051] The working principle and use process of this utility model:

[0052] First, the operator pours the straw on the top of the conveyor belt 2, and then drives the motor 3 to rotate the conveyor belt 2, so that the conveyor belt 2 drives the straw to move. In the process of moving the straw, the driving motor 2 6 rotates the push rod 5, so that the push rod 5 drives the rotating shaft 7 and the fixed rod 8 to rotate, so that the surface of the fixed rod 8 contacts the surface of the conveyor belt 2. In the process of contacting with the conveyor belt 2, a gap will appear between the rotating shaft 7 and the conveyor belt 2. Then, the rotation of the conveyor belt 2 is used as a power to drive the fixed rod 8 to drive the rotating shaft 7 to rotate. Then, the rotation of the rotating shaft 7 will make the straw pass through the gap between the rotating shaft 7 and the conveyor belt 2. When the straw passes through the rotating shaft 7, because the distance between the rotating shaft 7 and the conveyor belt 2 is fixed, the straw on the surface of the conveyor belt 2 The thickness is uniform, and then the straw will enter the crushing component 9, and then the straw will be crushed. During the rotation of the conveyor belt 2, the scraper 15 will continue to scrape the soil attached to the surface of the conveyor belt 2. During the scraping process, the driving motor 3 18 rotates the cam 19. During the rotation of the cam 19, it will push the fixed plate 16 to move, so that the fixed plate 16 drives the scraper 15 to move. During the movement of the fixed plate 16, the spring component 17 will be compressed. When the cam 19 is away from the surface of the fixed plate 16, the elasticity of the spring component 17 is used to make the fixed plate 16 drive the scraper 15 to move back and forth, thereby increasing the scraping effect. Then the scraped soil will enter the collection box 22 through the sewage outlet 21, and the scraped soil will be collected by the collection box 22. Finally, the operation process is completed.
