[0023] Compared with the prior art, the utility model has the advantages and positive effects of:

[0024] 1、By setting the speed adjusting assembly, when the support block exerts a pushing action on the lifting plate, the lifting plate will move in the upward direction along the sliding groove one under the cooperation of the sliding block and the sliding groove one. In this process, the shock absorber one will be subjected to a corresponding force, thereby pushing the speed reducer roller to make the speed reducer roller achieve a transmission connection state with the conveyor belt on the rubber belt machine body. Since the rotating speed of the speed reducer roller is relatively low, it will rely on the friction force generated between the speed reducer roller and the conveyor belt on the rubber belt machine body to slow down the rubber belt machine body. Through such a speed reduction effect, the speed of the rubber belt machine body can be gradually and slowly reduced, which can effectively prevent the conveyor belt from slipping due to the excessively rapid reduction of the speed of the rubber belt machine body, and is beneficial to improving the stability of the rubber belt machine body during the speed adjustment operation.

[0025] 2、By setting the transmission assembly, when the amount of goods decreases, the shock absorber two will act to push the guide roller support plate in the upward direction. Then, the guide roller support plate pushes the sliding plate through the connecting relationship of the connecting rod. The sliding plate can convert the received vertical force into horizontal force and use the converted horizontal force to push the push plate. Subsequently, the support block provided on the push plate will interact with the lifting plate to lift the lifting plate. Through this series of action processes, the guide roller support plate can flexibly control whether the speed reducer roller contacts the conveyor belt according to the weight of the goods carried by the rubber belt machine body, thereby effectively adjusting the running speed of the rubber belt machine body.

[0038] As shown in Figure 2 - Figure 3As shown, the transmission assembly 3 is arranged on one side of the speed adjusting assembly 2 and used to drive the speed reduction roller 24 and the conveyor body 1, the transmission assembly 3 comprises a guide roller support plate 31 slidably connected to the inner side of the support 21 and a sliding plate 34 arranged on the inner side of the support 21, the guide roller support plate 31 is fixedly connected with a connecting rod 33 on the side close to the sliding plate 34, the sliding plate 34 is provided with a sliding groove two 35 on the side close to the connecting rod 33, the connecting rod 33 is drivingly connected with the sliding plate 34 through the sliding groove two 35, the sliding plate 34 is fixedly connected with a push plate 32 on one side, and the push plate 32 is fixedly connected with a support block 36, the speed adjusting assembly 2 and the transmission assembly 3 are installed on the conveyor body 1, so that the speed of the conveyor body 1 can be adjusted according to the weight of the goods on the conveyor body 1, and the speed of the conveyor body 1 is kept in a stable speed range, when the goods on the conveyor body 1 are reduced, the damper two 6 drives the guide roller support plate 31 to move upward, the guide roller support plate 31 drives the sliding plate 34 through the connecting rod 33, the sliding plate 34 changes the vertical force into a horizontal force and drives the push plate 32, and the support block 36 on the push plate 32 lifts the lifting plate 22, so that the guide roller support plate 31 can control whether the speed reduction roller 24 is in contact with the conveyor belt according to the weight of the goods on the conveyor body 1, and adjust the speed of the conveyor body 1, when the support block 36 drives the lifting plate 22, the lifting plate 22 moves upward along the sliding groove one 26 through the sliding block 27, the damper one 23 drives the speed reduction roller 24 to be drivingly connected with the conveyor belt on the conveyor body 1, and the speed of the speed reduction roller 24 is lower than the speed of the conveyor body 1, when the speed reduction roller 24 is in contact with the conveyor belt on the conveyor body 1, the speed reduction roller 24 at low speed slows down the conveyor body 1 through the friction between the speed reduction roller 24 and the conveyor belt on the conveyor body 1, so that the speed of the conveyor body 1 is slowly reduced, and the phenomenon of slipping due to too fast speed reduction of the conveyor body 1 is avoided, thereby the stability of the conveyor body 1 during speed adjustment is improved.

[0039] Further, as shown in Figure 2 Figure 3 As shown: the lifting plate 22 and the support block 36 are provided with inclined surfaces 37 on the sides close to each other, and the support block 36 is drivingly connected with the support block 36 through the inclined surface 37, the inclined surfaces 37 are arranged on the support block 36 and the lifting plate 22, when the support block 36 is in contact with the lifting plate 22, the inclined surface 37 facilitates the support block 36 to lift the lifting plate 22, and the phenomenon of mutual clamping of the lifting plate 22 and the support block 36 is avoided.
