It can achieve multi-point material placement and material placement at different locations. The unloading trolley can adapt to high belt speed and large processing capacity conditions without damaging the belt and is easy to use. However, it also has some problems. When the unloading trolley's discharge port falls into the material pit, there is no sealing device, and the material bin is prone to overflow, which poses a safety hazard. Utility Model Content

[0003] To address the problems of existing technologies, the purpose of this utility model is to provide a sealing device for the discharge port of a mobile unloading trolley, which can effectively solve the problem of material overflowing from the discharge port and avoid causing safety hazards.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A sealing device for the discharge port of a mobile unloading trolley includes a housing, which is installed on the top of a hopper. A lower flange is provided on the top of the hopper, and an upper flange is welded to the lower part of the housing. The upper flange and the lower flange are fixed by bolts. Baffles are provided at both ends of the housing. Several pairs of fixing members are provided on the top of the housing. A boat-shaped discharge port is opened in the center of the housing. Clamping rods are provided on the fixing members. Fixing plates are provided on the bow parts on both sides of the boat-shaped discharge port. A sealing member is provided between the clamping rods.

[0005] Preferably, the two ends of the seal extend between the lower flange and the upper flange on both sides of the housing and are fixed by bolts. The seal at the boat-shaped discharge port position wraps around both sides of the housing along the edge of the boat-shaped discharge port.

[0006] Preferably, a level gauge is provided on the fixed plate.

[0007] The beneficial effects of this utility model are as follows: This utility model discloses a sealing device for the discharge port of a mobile unloading trolley. By adjusting the clamping rollers, the sealing element can achieve a good sealing degree, reduce dust, improve the working environment, and effectively prevent material leakage from the hopper.

[0008] This utility model discloses a sealing device for the discharge port of a mobile unloading trolley. A level gauge is installed on the fixed plate, which can effectively detect the total amount of material at the ship-shaped discharge port and feed it back to the control system of the mobile unloading trolley to prevent the material pile from reaching the maximum height limit.

[0010] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0011] like Figure 1 , Figure 2 , Figure 3 , Figure 4 The utility model shown is a sealing device for the discharge port of a mobile unloading trolley. The box body 1 is installed on the top of the silo. The top of the silo is provided with a lower flange 2. The lower part of the box body 1 is welded with an upper flange 3. The upper flange 3 and the lower flange 2 are fixedly connected by bolts 4. The two ends of the box body 1 are provided with baffles 5. The top of the box body 1 is provided with several pairs of fixing parts 6. The center of the box body 1 is provided with a boat-shaped discharge port 9. The two ends of the boat-shaped discharge port 9 are respectively provided with a pair of fixing parts 6. The fixing parts 6 are provided with clamping rods 8. The bow parts on both sides of the boat-shaped discharge port 9 are provided with fixing plates 11. The fixing plates 11 are provided with material level gauges 10, which can effectively detect the total amount of material in the boat-shaped discharge port and feed back to the control system of the mobile unloading trolley to prevent the material pile from reaching the maximum height limit. A sealing element 7 is provided between the clamping rollers 8. The two ends of the sealing element 7 extend to the lower flange 2 and upper flange 3 on both sides of the box body 1 and are fixed by bolts 4. The material coming out of the discharge port falls directly into the box body 1. The ship-shaped discharge port 9 in the middle of the box body 1 is provided with fixing plates 11 on both sides of the bow. The sealing element 7 along the edge of the ship-shaped discharge port 9 wraps around both sides of the box body 1. By adjusting the clamping rollers 8, the sealing element 7 can be made to have a good sealing degree, reduce dust, improve the working environment, and effectively prevent the material from overflowing from the silo.

[0012] In use, the unloading trolley unloads material from the boat-shaped unloading port 9. The clamping rollers 8 on the fixing part 6 are adjusted so that the sealing part 7 can be tightened during unloading, so that the sealing part 7 at the edge of the unloading port tightly surrounds the edge of the unloading trolley's outlet, achieving a better sealing effect. At the same time, the material level gauge 10 is observed to monitor the total amount of material in the box 1 at any time, and the unloading trolley's discharge situation is adjusted in time to effectively prevent material overflow from the hopper. After the unloading trolley finishes unloading, the clamping rollers 8 on the fixing part 6 are adjusted so that the sealing part 7 is loosened, and the unloading trolley's outlet can be moved away from the boat-shaped unloading port 9, thus completing the unloading work.

[0013] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
