[0007] Preferably, the baffle structure includes two pillars, which are respectively disposed on the front and rear sides of the fixed frame. The bottom ends of the pillars are fixedly connected to the vehicle body. A cross groove is provided on the inner side of each pillar, and a cross block is provided inside each cross groove. The cross block is slidably connected to the pillar. A U-shaped plate is fixedly connected between the two cross blocks. Multiple reinforcing rods are fixedly connected to the inner side of the U-shaped plate. An adjusting plate is fixedly connected between the multiple reinforcing rods. The adjusting plate is disposed inside the fixed frame.

[0008] Preferably, the baffle structure further includes a threaded rod disposed inside one of the cross grooves, the top end of the threaded rod passing through one of the cross blocks and threadedly connected to one of the cross blocks, and both ends of the threaded rod being rotatably connected to one of the support columns.

[0009] Preferably, a worm gear is fixedly connected to the outer side of the bottom end of the threaded rod, and a worm is meshed with the outer side of the worm gear. Both ends of the worm pass through the inner side of one of the cross grooves and are rotatably connected to one of the support columns. A throttle handle is installed at one end of the worm.

[0010] Preferably, the sliding component includes multiple sliding columns, all of which are fixedly connected to the top of the discharge box. The top ends of the multiple sliding columns penetrate the reciprocating plate and are slidably connected to the reciprocating plate. The multiple sliding columns limit the movement of the reciprocating plate, ensuring its stability when moving up and down.

[0011] Preferably, the driving component includes a rotating rod disposed at the bottom of the reciprocating plate.

The second sprocket and the first sprocket are connected by chain drive. The two support plates provide rotational support for the rotating rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this application, the second sprocket and the first sprocket are driven by a chain. The first sprocket drives the eccentric wheel to make eccentric motion through the rotating rod. The eccentric wheel is in contact with the rotating wheel. The rotating wheel drives the reciprocating plate to slide on multiple sliding columns. With the cooperation of multiple springs, the reciprocating plate drives the discharge plate to vibrate through multiple reciprocating rods. Therefore, the discharge of material can be accelerated through the multiple guide holes opened on the discharge plate, which improves the practicality of the device.

[0014] 2. This application uses a threaded rod to connect to one of the cross blocks. One of the cross blocks moves the other cross block through a U-shaped plate, so that the two cross blocks slide in two cross slots respectively. The U-shaped plate moves the adjusting plate through multiple reinforcing rods, so as to adjust the up and down position of the adjusting plate. After the adjusting plate is adjusted, there is a certain gap between the adjusting plate and the conveyor belt on the fixed frame. The material can be discharged through the gap between the adjusting plate and the conveyor belt on the fixed frame, so the discharge amount of the material can be controlled.

A feeding mechanism 2 and a connecting box structure 4 are provided on the top of the vehicle body 1. The connecting box structure 4 is located on one side of the feeding mechanism 2. A fixing frame 3 is installed on the top of the feeding mechanism 2. A baffle structure is provided on the outside of the fixing frame 3. A discharge box 5 is fixedly connected to one side of the connecting box structure 4. A discharge plate 16 is slidably connected inside the discharge box 5. Multiple guide holes are opened on the top of the discharge plate 16. A reciprocating plate 17 is provided on the top of the discharge plate 16. The four corners of the bottom of the reciprocating plate 17 are fixedly connected to... A reciprocating rod 18 is connected to the bottom of the reciprocating rod 18, which is fixedly connected to the discharge plate 16.

A rotating wheel 21 is installed at the center of the bottom of the reciprocating plate 17. An eccentric wheel 23 is provided at the bottom of the rotating wheel 21, and a driving component is provided on the outside of the eccentric wheel 23.

[0022] The driving component includes a rotating rod 22, which is located at the bottom of the reciprocating plate 17. One end of the rotating rod 22 passes through the eccentric wheel 23 and is fixedly connected to the eccentric wheel 23. Both ends of the outer side of the rotating rod 22 are rotatably connected to support plates 24. The two support plates 24 are fixedly connected to the two pillars 7 respectively. One end of the rotating rod 22 is fixedly connected to a first sprocket 25. A motor is fixedly connected to the top of the vehicle body 1. A second sprocket 26 is installed at the output end of the motor. The second sprocket 26 and the first sprocket 25 are connected by chain drive.

[0023] Specifically, when the material is discharged into the discharge box 5 through the fixed frame 3 and the connecting box structure 4, the motor is started. The motor model is not specifically limited, but is adapted to the equipment. The output end of the motor drives the second sprocket 26 to rotate. The second sprocket 26 and the first sprocket 25 are driven by a chain. The first sprocket 25 drives the eccentric wheel 23 to make eccentric motion through the rotating rod 22. The eccentric wheel 23 contacts the rotating wheel 21. The rotating wheel 21 drives the reciprocating plate 17 to slide on multiple sliding columns 19. With the cooperation of multiple springs 20, the reciprocating plate 17 drives the discharge plate 16 to vibrate through multiple reciprocating rods 18. Therefore, the discharge of material can be accelerated through the multiple guide holes opened on the discharge plate 16, which improves the practicality of the device.

[0024] The technology for the fixed frame 3 and the connecting box structure 4 adopts the scheme in the paver feeding device disclosed in CN220013271U.

[0025] like Figure 1 - Figure 3As shown, the baffle structure includes two support columns 7, which are respectively set on the front and rear sides of the fixed frame 3. The bottom end of the support column 7 is fixedly connected to the vehicle body 1. A cross groove 8 is opened on the inner side of each of the two support columns 7. A cross block 11 is provided inside each of the two cross grooves 8. The cross block 11 is slidably connected to the support column 7. A U-shaped plate 12 is fixedly connected between the two cross blocks 11. Multiple reinforcing rods 15 are fixedly connected to the inner side of the U-shaped plate 12. An adjusting plate 6 is fixedly connected between the multiple reinforcing rods 15. The adjusting plate 6 is set inside the fixed frame 3. The baffle structure also includes a threaded rod 9.

A worm 14 is meshed with the outer side of the worm gear 13. Both ends of the worm 14 pass through the inner side of one of the cross grooves 8 and are rotatably connected to one of the support columns 7. A throttle is installed at one end of the worm 14.

[0026] Specifically, when the throttle is turned, the worm gear 14 meshes with the worm wheel 13, and the worm wheel 13 drives the threaded rod 9 to rotate. The threaded rod 9 is threadedly connected to one of the cross blocks 11. One of the cross blocks 11 drives the other cross block 11 to move through the U-shaped plate 12, so that the two cross blocks 11 slide in the two cross grooves 8 respectively. The U-shaped plate 12 drives the adjusting plate 6 to move through multiple reinforcing rods 15, so as to adjust the up and down position of the adjusting plate 6. After the adjusting plate 6 is adjusted, there is a certain gap between the adjusting plate 6 and the conveyor belt on the fixed frame 3. The material can be discharged through the gap between the adjusting plate 6 and the conveyor belt on the fixed frame 3, so the discharge amount of the material can be controlled.
