The setting of the guide shaft 503 makes the adjusting block 301 move more smoothly. The second spring 504 contracts, and at the same time, the adjusting block 301 adjusts the position of the cleaning brush 303 so as to clean different positions of the scraper 204 and improve the cleaning effect. The guide shaft 503 is fixedly connected to the conveying body 1, and a second spring 504 is fixedly connected between the adjusting block 301 and the conveying body 1.

[0025] Specifically, such as Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown, the material guiding structure 4 includes a lower hopper 401 fixedly connected to the conveying body 1 and two adjusting shafts 402 rotatably connected to the lower hopper 401, the adjusting shaft 402 is fixedly connected to a connecting frame 403, and a guide plate 404 is slidably connected to the connecting frame 403. The two inclined guide plates 404 can slow down the falling speed of the material into the conveying body 1, thereby avoiding the impact of the scraper 204 due to the excessive falling speed of the material, and preventing the scraper 204 from being damaged. The guide plate 404 is fixedly connected to a fixing seat 405, and the fixing seat 405 is slidably connected to the connecting frame 403. A vibration motor 408 is installed on the fixing seat 405. A slide plate 407 is fixedly connected to the guide plate 404, and the slide plate 407 is slidably connected to the connecting frame 403. A first spring 406 is fixedly connected between the guide plate 404 and the connecting frame 403. The adjusting shaft 402 is fixed by a limiting structure 6. The structure 6 includes two limiting shafts 601 fixedly connected to the lower hopper 401 and a limiting block 602 engaged with the limiting shaft 601. The limiting block 602 is provided with a plurality of limiting holes 603. The plurality of limiting holes 603 are distributed in a circular array about the center of the adjustment shaft 402. The limiting shaft 601 is engaged with two of the limiting holes 603. After the adjustment is completed, the limiting block 602 is released so that the limiting block 602 is engaged with two of the limiting holes 603 under the action of the third spring 606. The limiting hole 603 is engaged, and the limiting shaft 601 is engaged with the limiting block 602, which facilitates the fixing of the adjusting shaft 402 after rotation and improves stability. The limiting block 602 is fixedly connected with a sliding rod 604, and the sliding rod 604 is slidably connected to the adjusting shaft 402. The sliding rod 604 is fixedly connected with a slider 605, and the slider 605 is slidably connected to the adjusting shaft 402. A third spring 606 is fixedly connected between the slider 605 and the adjusting shaft 402.

[0026] When the present invention is in use, first, when the material enters the conveyor body 1, it will pass through the lower hopper 401 and then fall onto the guide plate 404. The two inclined guide plates 404 can slow down the material falling into the conveyor body 1, thereby avoiding the material from impacting the scraper 204 due to the excessive falling speed, and preventing the scraper 204 from being damaged. The operator can adjust the angle of the adjustment shaft 402 according to actual needs. When adjusting, pull the limit block 602, the limit block 602 will drive the slide bar 604 to slide, and when the slide bar 604 slides, it drives the slider 605 to slide, and the slider 605 will cause the third spring 606 to contract. At the same time, the limit block 602 is no longer engaged with the limit shaft 601. At this time, the limit block 602 and the slide bar 604 can drive The adjusting shaft 402 rotates to change the angles of the connecting frame 403 and the guide plate 404 to adapt to different material conveying requirements. After the adjustment is completed, the limit block 602 is loosened, so that the limit block 602 is engaged with two of the limit holes 603 under the action of the third spring 606. The limit shaft 601 is engaged with the limit block 602, which facilitates the fixing of the rotating adjusting shaft 402 and improves stability. At the same time, the vibration motor 408 is started, and the guide plate 404 vibrates under the action of the vibration motor 408 to promote the flow of materials and prevent materials from piling up on the guide plate 404. The sliding connection between the slide plate 407 and the connecting frame 403 ensures the stability of the vibration of the guide plate 404. At the same time, the first spring 406 is continuously deformed. When conveying the material entering the conveyor body 1, the first driving member 209 (preferably a motor) is first started. The first driving member 209 drives one of the mounting shafts 201 to drive the sprocket 202 to rotate. The sprocket 202 cooperates with the chain 203 so that the two chains 203 drive the scraper 204 on the chain 203 to move, thereby realizing material conveying. When the scraper 204 moves to a certain position, the guide rod 205 enters the guide rail 206, and the guide rod 205 slides in the guide rail 206. This setting can prevent the scraper 204 from increasing the friction between the scraper 204 and the conveyor body 1 when the scraper 204 is subjected to force on one side, thereby improving the service life of the scraper 204 and ensuring the stability of transportation. At the same time, the guide wheel 208 rolls in the guide rail 206, reducing the friction and making the movement more stable. When the guide wheel 208 needs to be replaced, the hexagonal sleeve is inserted into the hexagonal block at the end of the screw rod 704 and the screw rod 704 is rotated 180 degrees. The screw rod 704 will drive the inclined connecting plate 705 to rotate. The inclined connecting plate 705 will push the roller 702 to drive the installation rod 701 to move, so that the installation rod 701 and the positioning sleeve 703 are no longer engaged. By engaging the installation rod 701 with the positioning sleeve 703, it is convenient to install the guide rod 205 on the scraper 204, improving stability. At this time, the guide rod 205 can be pulled out from the positioning sleeve 703 to complete the disassembly. The identification block 706 is used to indicate the rotation position of the screw rod 704 to ensure that it is installed in place. When replacing, it is only necessary to plug the guide rod 205 into the positioning sleeve 703, and then engage the installation rod 701 with the positioning sleeve 703 to complete the installation. When the scraper 204 needs to be cleaned, the second driving member 306 (preferably a motor) is started, and the second driving member 306 drives the connecting shaft 302 to drive the cleaning brush 303 to rotate. The two cleaning brushes 303 are engaged through the gear 304 to realize reverse rotation. At the same time, the connecting pipe 309 is connected to an external water source, and the chain 203 is flushed through the nozzle 310 to improve the cleanliness. The cleaning brush 303 cleans the material adhered to the scraper 204 to prevent the material from adhering to the scraper 204 and affecting the material conveying efficiency. In addition, when the driving shaft 50 During rotation, the cam 501 pushes the adjusting block 301 upward along the guide shaft 503. The setting of the guide shaft 503 makes the adjusting block 301 move more smoothly. The second spring 504 contracts, and at the same time, the adjusting block 301 adjusts the position of the cleaning brush 303 so as to clean different positions of the scraper 204 and improve the cleaning effect. Moreover, when conveying materials, the cleaning brush 303 can be moved to the highest position to avoid affecting the movement of the scraper 204. When the adjusting block 301 moves, it slides more smoothly through the guide plate 308.
