[0024] Specifically, the angle adjustment mechanism 3 includes a fixed frame 31, a rotating shaft 32, a driving gear 33, a first driven rack 34, a second driven rack 35, a first slide 36, a second slide 37, a first inclined top block, a second inclined top block, a connecting rod 310, and a spring 311. The fixed frame 31 is fixedly connected to the belt conveyor bracket, the rotating shaft 32 is connected to the fixed frame 31 through a bearing 39, the rotating shaft 32 passes through the inner ring of the bearing 39 and is fixed to the inner ring of the bearing 39, the outer ring of the bearing 39 is connected to the fixed frame 31, the driving gear 33 is connected to the lower end of the rotating shaft 32, the first driven rack 34 and the second driven rack 35 are arranged on the front and rear sides of the driving gear 33, the front end of the first driven rack 34 is connected to the first inclined top block, and the first driven rack 34 is arranged under the first slide The first driven rack 34 can slide in the first slide groove 36, the front end of the second driven rack 35 is connected to the second inclined top block, and the second driven rack 35 is provided with a second slide groove 37. The second driven rack 35 can slide in the second slide groove 37. The first slide groove 36 and the second slide groove 37 are connected to the fixing frame 31. One end of the connecting rod 310 is hinged on the inner side of the oblique portion 22, and the connecting rod 310 passes through the connecting bracket 1 above it. A limiting block is provided at the other end of the connecting rod 310. A spring 311 is sleeved on the part of the connecting rod 310 located between the oblique portion 22 and the connecting bracket 1. The limiting mechanism 38 is used to limit the driving gear 33 or the first driven rack 34 and the second driven rack 35 after the adjustment of the driving gear 33 is completed.

[0025] Specifically, the limiting mechanism 38 includes a limiting disc 3801 and a limiting pin 3802. The limiting disc 3801 is arranged above the driving gear 33, and the limiting disc 3801 is fixed on the fixing frame 31. The driving gear 33 is provided with a through hole that matches the limiting pin 3802, and the limiting disc 3801 is provided with a plurality of pin holes that match the through hole.

[0026] After installation, the first inclined top block and the second inclined top block are against their respective corresponding baffles 4, and the driving gear 33 is rotated clockwise, and the driving gear 33 drives the first driven rack 34 and the second driven rack 35 to move to both sides, and the first inclined top block and the second inclined top block press against their respective corresponding baffles 4 with the connection between the baffle 4 and the inclined portion 22 as the axis to rotate. After adjusting to a certain angle according to actual needs, the limit pin 3802 is inserted into the pin hole on the limit disk 3801, and then the limit pin 3802 is inserted into the through hole corresponding to the pin hole of the driving gear 33 and the limit disk 3801.

After installation, the side of the baffle 4 away from the belt will exceed the oblique portion 22. After the angle adjustment mechanism 3 is adjusted, the baffle 4 shields the material and can effectively shield the dust. The baffle 4 is avoided accordingly with respect to the angle adjustment mechanism 3.

[0028] like Figure 5 As shown, optionally, the baffle 4 is a rectangular plate, and the first adjustment slot 41 opens from the side of the baffle 4 and extends to the middle. This baffle 4 is used when conveying materials without dust or with less dust.
