DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] For example 1, please refer to Figures 1-4 , a self-drying biomass pellet making device, comprising: A granulation bin 100, a granulation roller 200 is installed inside the granulation bin 100, and a placement plate 300 with through holes is installed inside the granulation bin 100; The hot air duct 400 is installed at the bottom of the pelletizing bin 100; A resilient cleaning shovel 501 is installed inside the pelletizing bin 100, and a sprocket 1 502 is connected to the side of the pelletizing roller 200. The pelletizing roller 200, driven by a servo motor, is activated to drop raw materials from the top of the pelletizing bin 100 into the bin for pelletizing. The resilient cleaning shovel 501, installed inside the bin 100 and positioned to the side of the pelletizing roller 200, scrapes off any raw materials that may be adhering to the roller 200 as it rotates. Simultaneously, the roller 200 drives the sprocket 1 502, which is connected to it, to rotate.

[0022] The interior of the granulation bin 100 is equipped with a fixed table 503, and the interior of the fixed table 503 is slidably connected to a movable table 504, and the top of the movable table 504 is equipped with a cleaning brush 505. The side of the granulation bin 100 is equipped with a liquid pump switch 506, and the side of the granulation bin 100 is equipped with an injection pipe 507 connected to the liquid pump. A transmission member for transmission is equipped between the cleaning brush 505 and the sprocket 1 502, and the transmission member includes a chain 1 508 assembled on the outside of the sprocket 1 502. The interior of the fixed table 503 is rotatably connected to a reciprocating screw rod 509 that passes through it. The movable table 504 is assembled at the outside position of the reciprocating screw rod 509 and is connected to the reciprocating screw rod 509 by setting a thread. The outside of the reciprocating screw rod 509 is fixedly connected to the sprocket 2 510, and the end of the chain 1 508 is away from the sprocket 1 502 and is assembled at the outside position of the sprocket 2 510. When sprocket 1 502 rotates, it cooperates with chain 1 508 mounted on the outside of sprocket 1 502, causing sprocket 2 510, which is connected to sprocket 1 502 through chain 1 508, to rotate. Sprocket 2 510 then drives the reciprocating screw 509 fixed to it to rotate. Moreover, the movable platform 504, which is threadedly mounted on the outside of the reciprocating screw 509, is restricted by the fixed platform 503 with which it is slidably connected. As the reciprocating screw 509 rotates, the movable platform 504 can reciprocate horizontally, driving the cleaning brush 505 mounted on the top of the movable platform 504 to reciprocate horizontally, thereby scraping raw materials that may be attached to the bottom of the cleaning shovel 501 onto the cleaning brush 505. In this way, the cleaning shovel 501 can be intermittently cleaned when the device is in use, thereby improving the effectiveness of the cleaning shovel 501 on the granulating roller 200 and reducing the possibility of raw materials adhering to the granulating roller 200.

[0023] When the movable platform 504 moves to the liquid pump switch 506 and the liquid pump switch 506 is squeezed, the liquid pump is activated, and the cleaning liquid flows through the injection pipe 507 to the cleaning brush 505 located at this time, and the cleaning brush 505 is rinsed, thereby improving the use effect of the cleaning brush 505 on the cleaning shovel 501, and further reducing the possibility of raw materials adhering to the granulating roller 200.

[0024] As the movable platform 504 continues to move away from the liquid pump switch 506, the liquid pump can be stopped, thereby stopping the injection of the cleaning liquid.

[0025] When in use, the granulating roller 200 driven by the servo motor is activated, and the raw materials are put into the granulating bin 100 from the top of the granulating bin 100 to perform the corresponding granulation operation, and the cleaning shovel 501 with a certain elasticity installed inside the granulating bin 100 is located at the side of the granulating roller 200. As the granulating roller 200 rotates, the cleaning shovel 501 can scrape off the raw materials that may be attached to the granulating roller 200. At the same time, the granulating roller 200 drives the sprocket 1 502 connected to it to rotate, and cooperates with the chain 1 508 installed on the outside of the sprocket 1 502 to rotate the sprocket 2 510 connected to the sprocket 1 502 through the chain 1 508. The sprocket 2 510 then drives the reciprocating screw rod 509 fixed to it to rotate, and is screwed on the reciprocating screw rod. The movable platform 504 outside the rod 509 is restricted by the fixed platform 503 to which it is slidably connected, so that when the reciprocating screw rod 509 rotates, the movable platform 504 can move back and forth in the horizontal direction, driving the cleaning brush 505 assembled on the top of the movable platform 504 to move back and forth in the horizontal direction, so that the raw materials that may be attached to the bottom of the cleaning shovel 501 can be scraped onto the cleaning brush 505. When the movable platform 504 moves to the liquid pump switch 506 and the liquid pump switch 506 is squeezed, the liquid pump can be enabled to flow the cleaning liquid through the injection pipe 507 to the cleaning brush 505 located at this time, so as to rinse the cleaning brush 505; and as the movable platform 504 continues to move away from the liquid pump switch 506, the liquid pump can be stopped, thereby stopping the injection of cleaning liquid.

[0026] For example 2, please refer to Figure 1-Figure 5 Based on the first embodiment, an auxiliary cleaning assembly 600 for cleaning the cleaning brush 505 is installed on the side of the pelletizing bin 100. The auxiliary cleaning assembly 600 includes a bevel gear 1 601 mounted on the outside of the reciprocating screw 509. A transmission rod 602 is rotatably connected to the side of the pelletizing bin 100. When the reciprocating screw 509 is in a rotating state, it can drive the bevel gear 1 601 mounted on its outside to rotate, so that the bevel gear 1 601 drives the meshing bevel gear 2 603 to rotate, and the bevel gear 2 603 drives the transmission rod 602 fixedly connected to it to rotate.

[0027] The bottom of the transmission rod 602 is fixedly connected to bevel gear 2 603, which is located on the side of bevel gear 1 601 and is in meshing state with bevel gear 1 601. The outer side of the transmission rod 602 is fixedly connected to sprocket 3 604, and the outer side of sprocket 3 604 is equipped with chain 2 605. The bottom of the injection pipe 507 is rotatably connected to the pipe joint 606, and the outer side of the pipe joint 606 is fixedly connected to sprocket 4 607. The end of chain 2 605 is away from sprocket 3 604 and is equipped on the outer side of sprocket 4 607. The bottom of the pipe joint 606 is equipped with a nozzle 608. When the transmission rod 602 is in a rotating state, the transmission rod 602 drives the sprocket three 604 fixedly connected to it to rotate, and cooperates with the chain two 605 assembled on the outside of the sprocket three 604 to rotate the sprocket four 607 connected to the sprocket three 604 through the chain two 605. The sprocket four 607 then drives the pipe joint 606 fixedly connected to it to rotate. Because the pipe joint 606 and the injection pipe 507 are in a rotating connection state, when the cleaning liquid flows rapidly in the injection pipe 507, it can be injected into the nozzle 608 through the pipe joint 606 and then sprayed out through the rotation of the nozzle 608, thereby increasing the coverage area of ​​the cleaning liquid, thereby improving the cleaning efficiency of the device for the cleaning brush 505.

[0028] During use, based on the first embodiment, when the reciprocating screw rod 509 is in a rotating state, it can drive the bevel gear 1 601 assembled on the outside thereof to rotate, so that the bevel gear 1 601 drives the bevel gear 2 603 meshing with it to rotate, and the bevel gear 2 603 drives the transmission rod 602 fixedly connected to it to rotate, so that the transmission rod 602 drives the sprocket 3 604 fixedly connected to it to rotate, and cooperates with the chain 2 605 assembled on the outside of the sprocket 3 604, so that the sprocket 4 607 connected to the sprocket 3 604 through the chain 2 605 rotates, and the sprocket 4 607 then drives the pipe joint 606 fixedly connected to it to rotate, and because the pipe joint 606 and the injection pipe 507 are in a rotating connection state, when the cleaning liquid flows rapidly in the injection pipe 507, it can be injected into the nozzle 608 through the pipe joint 606, and then sprayed out through the rotation of the nozzle 608.

[0029] For example three, please refer to Figures 1-8 Based on the first and second embodiments, the pelletizing bin 100 is equipped with a hot air diversion assembly 700. The diversion assembly 700 includes a hydraulic chamber 701 mounted on the side of the pelletizing bin 100, and an elastic cam 702 is mounted on the outer side of the reciprocating screw 509. When the hot air blower is activated, hot air is introduced into the pelletizing bin 100 through the hot air duct 400. When the reciprocating screw 509 is in a rotating state, the reciprocating screw 509 drives the elastic cam 702 mounted on its outer side to rotate.

[0030] One end of the hydraulic bin 701 is connected to a force-bearing rod 703 by setting a piston for sliding. The force-bearing rod 703 is located at the top position of the elastic cam 702 and is in contact with the elastic cam 702. The other end of the hydraulic bin 701 is connected to an arc rod 704 by setting a piston for sliding. The bottom of the force-bearing rod 703 is equipped with a spring 705. The interior of the granulating bin 100 is rotatably connected to a penetrating rotating rod 706. The outer sides of the rotating rod 706 are fixedly connected to a force-bearing plate 707 and a guide plate 708 respectively. The force-bearing plate 707 is located at the side of the arc rod 704 and is fixed to the arc rod 704. When the protruding part of the elastic cam 702 rotates to the force-bearing rod 703, it can squeeze the force-bearing rod 703 and drive the force-bearing rod 703 to move downward, squeezing the oil in the hydraulic chamber 701, so that the oil originally stored in the hydraulic chamber 701 moves to the side close to the arc rod 704, thereby pushing the arc rod 704 out of the hydraulic chamber 701, so that the arc rod 704 drives the force-bearing plate 707 fixedly connected to it to rotate, and when the protruding part of the elastic cam 702 moves away from the force-bearing rod 703 as it rotates, the force-bearing plate 707 is rotated. When the force rod 703 loses its restriction, it can be reset under the action of the spring 705, and similarly, the force plate 707 can be reset. In this way, the force plate 707 can be rotated back and forth at a certain angle, driving the rotating rod 706 fixedly connected to the force plate 707 to rotate back and forth, so that the rotating rod 706 drives the guide plate 708 fixedly connected to it to rotate back and forth, and the hot air blown in through the hot air duct 400 is diverted to the two sides of the bottom of the placement plate 300, so that the particles are heated more evenly, thereby improving the drying efficiency of the device.

[0031] When in use, on the basis of Example 1 and Example 2, the hot air blower is activated to pass the hot air into the pelletizing bin 100 through the hot air duct 400, and when the reciprocating screw 509 is in a rotating state, the reciprocating screw 509 can drive the elastic cam 702 assembled on the outside thereof to rotate, and when the protruding part of the elastic cam 702 rotates to the force-bearing rod 703, the force-bearing rod 703 can be squeezed and driven to move downward, squeezing the oil in the hydraulic bin 701, so that the oil originally stored in the hydraulic bin 701 moves to the side close to the arc rod 704, thereby pushing the arc rod 704 out of the hydraulic bin 701. The arc rod 704 drives the force-bearing plate 707 fixedly connected to it to rotate. When the protruding part of the elastic cam 702 moves away from the force-bearing rod 703 as it rotates, the force-bearing rod 703 loses its restriction and can be reset under the action of the spring 705. Similarly, the force-bearing plate 707 is reset. In this way, the force-bearing plate 707 can be reciprocated at a certain angle, driving the rotating rod 706 fixedly connected to the force-bearing plate 707 to rotate reciprocatingly, so that the rotating rod 706 drives the guide plate 708 fixedly connected to it to rotate reciprocatingly, and the hot air blown in through the hot air duct 400 is guided to the two sides of the bottom of the placement plate 300.

[0032] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
