The inner side of the gear 104 is fixedly connected with a rotating rod 103.

[0031] Specifically, the motor 1 controls the rotating rod 101 to rotate, and the rotation of the rotating rod 101 will drive the gear 105 to rotate synchronously, and then drive the gear 104 to rotate through the belt 102, and the rotation of the gear 104 will drive the rotating rod 103 to rotate, thereby generating a linkage between the primary treatment box 5 and the secondary treatment box 4, which is convenient for the management of soil treatment.

[0032] See also Figure 4 The primary processing box 5 includes a box body 506 connected to the motor 1, an opening is provided at the upper end of the box body 506, and the opening is fixedly connected to the feed port 7, an opening 2 is provided on one side of the box body 506, and the opening 2 is rotatably connected to the rotating rod 101, a crushing tank 502 is provided inside the box body 506, and a plurality of sieve holes are provided on the outer side of the crushing tank 502, and an outlet 510 is fixedly connected to the side of the crushing tank 502 close to the feed port 7.

[0033] See also Figure 7 and Figure 8 , partitions 507 are rotatably connected to both sides of the crushing tank 502, and the partitions 507 are fixedly connected to the box body 506, and the gear 105 is located between the partitions 507 and the box body 506. A cutting plate 504 is arranged inside the crushing tank 502, and the cutting plate 504 is rotatably connected to the rotating rod 101. Side plates 508 are fixedly connected to both sides of the crushing tank 502, and a ratchet 2 505 is fixedly connected to the center of the side plates 508.

[0034] See also Figure 6 and Figure 7 The inner side of ratchet wheel 2 505 is meshed with ratchet wheel 3 509, ratchet wheel 3 509 is fixedly connected to the rotating rod 101, the end of ratchet wheel 2 505 away from the cutting plate 504 is fixedly connected with ratchet wheel 1 503, ratchet wheel 1 503 is rotatably connected to the rotating rod 101, a connecting disk 501 is provided on the outer side of ratchet wheel 1 503, a ratchet is provided at the center of the connecting disk 501, the ratchet is meshed with ratchet wheel 1 503, the connecting disk 501 is fixedly connected to the partition 507, and the ratchet is provided at the center of the connecting disk 501 and the ratchet is meshed with ratchet wheel 1 503, so that the reverse rotation of ratchet wheel 1 503 will be restricted to a certain extent, so that the rotating rod 101 can have different effects when rotating forward and reverse.

[0035] Specifically, soil enters the crushing tank 502 from the feed port 7 through the outlet 510. After the motor 1 is started, it will control the rotating rod 101 to rotate forward. The rotation of the rotating rod 101 will drive the ratchet three 509 to rotate forward synchronously. The forward rotation of the ratchet three 509 will drive the ratchet two 505 to rotate forward. The forward rotation of the ratchet two 505 will drive the ratchet one 503 to rotate. Because the ratchet one 503 is meshed with the ratchet on the connecting plate 501, and the connecting plate 501 is in a fixed state, there is a certain restriction on the rotation direction of the ratchet one 503. When the rotating rod 101 rotates forward, the ratchet two 505 will rotate on the side plate 508, and will not drive the crushing tank 502 to rotate. At the same time, the rotation of the rotating rod 101 will drive the cutting plate 504 to rotate synchronously, thereby cutting and crushing the soil inside the crushing tank 502. The soil in the 02 sieve holes will directly pass through the discharge port 8 to the collection box 2 for collection. When the motor 1 controls the rotating rod 101 to reverse, the connecting disk 501 will not restrict the rotation of the ratchet 1 503, so that the ratchet 1 503 can be reversed synchronously, and then the ratchet 2 505 can be reversed. The reversal of the ratchet 2 505 will drive the side plate 508 to rotate synchronously, and then the crushing tank 502 can be reversed synchronously. While the crushing tank 502 is reversing, the cutting plate 504 inside the crushing tank 502 will continue to rotate, driving the soil in the crushing tank 502 to flow out from the outlet 510 to the secondary processing box 4 for recovery, and by controlling the reversal rate, the reversal rate is reduced, thereby reducing the probability that the cutting plate 504 cuts the soil inside the crushing tank 502 when the crushing tank 502 is reversed.

[0036] See also Fig. 9 The secondary processing box 4 includes a box body 401 connected to the primary processing box 5, and a gear 2 412 is arranged inside the box body 401.

The outer side of the gear 2 412 is transmission-connected with a belt 414, and the side of the belt 414 away from the gear 2 412 is transmission-connected with a gear 3 413. There are two gears 3 413 and they are symmetrically distributed with the gear 2 412 as the symmetry axis. Each gear 3 413 is fixedly connected with a threaded rod 407 on a side close to the primary processing box 5, and the end of the gear 3 413 close to the rotating rod 103 is rotationally connected with a fixed block 1 415, and the fixed block 1 415 is fixedly connected to the box body 401, and a section of the threaded rod 407 close to the fixed block 1 415 is not provided with threads.

[0038] See also Fig. 9 and Fig.10 The end of the connecting plate 2 410 away from the connecting plate 1 404 is fixedly connected to the recycling box 402, and fixed blocks are fixedly connected to both sides of the recycling box 402, and the fixed blocks are rotatably connected to the threaded rod 407. The end of the recycling box 402 away from the connecting plate 2 410 is provided with a fixing plate 1 406, and the fixing plate 1 406 is rotatably connected to the threaded rod 407 and fixedly connected to the box body 401. The threaded rod 407 is not provided with a thread at a section close to the fixing plate 1 406. The threaded rod 407 is on both sides of the fixing plate 2 416 and the fixing plate 405. There are no threads on the sides, and a humidity detector and a gravity sensor are provided on the recycling box 402. By providing the humidity detector and the gravity sensor, when the humidity detector on the drying plate 418 detects that the moisture content in the soil meets the standard, the motor 1 will be controlled to drive the rotating rod 101 to reverse. When the gravity sensor on the drying plate 418 reaches the maximum value but the value on the humidity detector does not meet the standard, the device will be controlled to stop running, and an alarm signal will be released to remind the staff to check the device, thereby improving the safety of the device operation.

[0039] See also Fig. 9 and Fig.11A scraper 409 is fixedly connected between the two fixed plates 405, and the scraper 409 is located below the heating tube 408. A drying plate 418 is slidably connected to the lower end of the scraper 409. The drying plate 418 is fixedly connected to the connecting plate 1 404 on the side close to the gear 2 412. A power supply box 417 is arranged between the connecting plate 1 404 and the fixed block 1 415. The power supply box 417 is electrically connected to the heating tube 408. By setting the power supply box 417, the operation of the power supply box 417 is related to the forward and reverse rotation of the rebound block 411 and the motor 1, so that the heating tube 408 can work during collection, and the heating tube 408 can be relaxed during recycling, thereby increasing the service life of the heating tube 408.

[0040] Specifically, when the rotating rod 103 rotates forward, it will drive the gear 2 412 to rotate synchronously. The rotation of the gear 2 412 will drive the gear 3 413 to rotate through the belt 414. The rotation of the gear 3 413 will synchronously drive the threaded rod 407 to rotate. The rotation of the threaded rod 407 will make the connecting plate 1 404, the connecting plate 2 410 and the fixed plate 1 406 move synchronously, so that the heating tube 408 can move in the secondary treatment box 4. When the connecting plate 1 404 moves to contact with the fixed plate 405, the connecting plate 1 404 is no longer affected by the force of the threads on the threaded rod 407. Under the action of inertia, the connecting plate 1 404 will contact with the fixed plate 405, so that the connecting plate 1 The rebound block 411 on 404 will contact the fixed plate 405, and the elastic force of the rebound block 411 will push the connecting plate 404 away from the fixed plate 405, so that the connecting plate 404 will contact the threads on the threaded rod 407 again, thereby realizing reciprocating motion. At the same time, the cut soil at the primary processing box 5 will fall to the drying plate 418 through the sieve holes. When the connecting plate 404 contacts the fixed plate 405, the trigger block on the fixed plate 405 will control the power supply box 417 to supply power to the heating tube 408, so that the heating tube 408 can dry the soil on the drying plate 418. When the humidity detector on the drying plate 418 detects that the humidity content in the soil reaches When the gravity sensor on the drying plate 418 reaches the maximum value but the value on the humidity detector does not meet the standard, the device will be controlled to stop running and an alarm signal will be released to remind the staff to check the device. When the rotating rod 103 starts to reverse, the power supply box 417 will stop supplying power to the heating tube 408, so that the heating tube 408 can be relaxed for a certain period of time, thereby increasing the service life of the heating tube 408. At the same time, the connecting plate 404 will contact the thread again under the action of the rebound block 411, and will reset under the influence of the reversal of the threaded rod 407. At this time, the drying plate 418 will move synchronously with the connecting plate 404. When moving, the scraper 409 will intercept the soil on the drying plate 418, so that the soil on the drying plate 418 can fall into the collecting box 2 through the discharge port 8, and when the connecting plate 404 moves to contact with the fixed block 415, it will continue to reciprocate under the action of the rebound block 411 on the other side of the connecting plate 404. At this time, the recycling box 402 is located below the primary processing box 5, and the soil that does not pass through the sieve hole in the primary processing box 5 can fall into the recycling box 402. After a period of time, the motor 1 starts to rotate forward again, and the recycling box 402 will be reset. The staff can collect the soil in the recycling box 402 and remix it for crushing and screening again.

[0041] Working principle of the present invention: after the device is started, the soil falls into the crushing tank 502 from the feed port 7 through the outlet 510. After the motor 1 is started, it will control the rotating rod 101 to rotate forward. The rotation of the rotating rod 101 will drive the gear 105 to rotate synchronously, and then drive the gear 104 to rotate through the belt 102. The rotation of the gear 104 will drive the rotating rod 103 to rotate, and the rotation of the rotating rod 101 will drive the ratchet three 509 to rotate forward synchronously. The forward rotation of the ratchet three 509 will drive the ratchet two 505 to rotate forward. The forward rotation of the ratchet two 505 will drive the ratchet one 503 to rotate. Because the ratchet one 503 is meshed with the ratchet on the connecting disk 501, and the connecting disk 501 is in a fixed state, There is a certain restriction on the rotation direction of the ratchet wheel 1 503, so that when the rotating rod 101 rotates forward, the ratchet wheel 2 505 will rotate on the side plate 508, and will not drive the crushing tank 502 to rotate. At the same time, the rotation of the rotating rod 101 will drive the cutting plate 504 to rotate synchronously, thereby cutting and crushing the soil inside the crushing tank 502. At this time, the soil passing through the sieve holes of the crushing tank 502 will be directly collected in the collection box 2 through the discharge port 8. When the rotating rod 103 rotates forward, it will drive the gear 2 412 to rotate synchronously. The rotation of the gear 2 412 will drive the gear 3 413 to rotate through the belt 414. The rotation of the gear 3 413 will synchronously drive the threaded rod 407 to rotate. The rotation of 407 will make the connecting plate 1 404, the connecting plate 2 410 and the fixing plate 1 406 move synchronously, so that the heating tube 408 can move in the secondary processing box 4. When the connecting plate 1 404 moves to contact with the fixing plate 405, the connecting plate 1 404 is no longer subjected to the force of the threads on the threaded rod 407. Under the action of inertia, the connecting plate 1 404 will contact with the fixing plate 405, so that the rebound block 411 on the connecting plate 1 404 will contact with the fixing plate 405. Under the action of the elastic force of the rebound block 411, the connecting plate 1 404 will be pushed away from the fixing plate 405, so that the connecting plate 1 404 will reconnect with the threads on the threaded rod 407. The soil after cutting at the primary processing box 5 will fall to the drying plate 418 through the sieve hole. When the connecting plate 404 contacts the fixing plate 405, the power supply box 417 will supply power to the heating tube 408 synchronously, so that the heating tube 408 can dry the soil on the drying plate 418. When the humidity detector on the drying plate 418 detects that the humidity content in the soil meets the standard, the motor 1 will be controlled to drive the rotating rod 101 to reverse. When the gravity sensor on the drying plate 418 reaches the maximum value but the value on the humidity detector does not meet the standard, the device will be controlled to stop running, and an alarm signal will be released to remind the staff to check the device.

[0042] When the motor 1 controls the rotating rod 101 to reverse, the connecting disk 501 will not restrict the rotation of the ratchet wheel 1 503, so that the ratchet wheel 1 503 can be reversed synchronously, and then the ratchet wheel 2 505 can be reversed. The reversal of the ratchet wheel 2 505 will drive the side plate 508 to rotate synchronously, so that the crushing tank 502 can be reversed synchronously. While the crushing tank 502 is reversing, the cutting plate 504 inside the crushing tank 502 will continue to rotate, driving the soil in the crushing tank 502 to flow out from the outlet 510 to the secondary treatment box 4 for recycling, and by controlling the reversal rate, the reversal rate is reduced, thereby reducing the probability that the cutting plate 504 cuts the soil inside the crushing tank 502 when the crushing tank 502 is reversed, and when the rotating rod 103 starts to reverse, the power supply box 417 will stop supplying power to the heating tube 408, so that the heating tube 408 can be relaxed for a certain period of time, increasing the heating tube When the connecting plate 404 is moved to contact with the fixed block 415, it will continue to reciprocate under the action of the rebound block 411 on the other side of the connecting plate 404. At this time, the recycling box 402 is located below the primary processing box 5. The soil that has not passed through the sieve hole in the primary processing box 5 can fall into the recycling box 402. After a period of time, the motor 1 starts to rotate forward again. At this time, the recycling box 402 will be reset, and the staff can collect the soil in the recycling box 402 and remix it for feeding.
