Description

Technical Field

[0001] The utility model relates to the technical field of material transportation, in particular to a chute with adjustable material drop point. Background Art

[0002] The mining, metallurgy, and coal industries often use belt conveyors to transport materials. The upstream belt conveyor transfers material to the downstream belt conveyor via a chute. If the upstream and downstream belt conveyors are not aligned, the drop point must be centered on the downstream belt conveyor; otherwise, the belt conveyor will often deviate. Unstable material flow during belt conveyor operation can also cause the drop point to deviate, causing the downstream belt conveyor to deviate. Currently, a common practice is to add an adjustment plate to the upstream belt conveyor's head guard. However, after the material has been hurled through the chute for a long distance, the drop point will still shift, making this adjustment limited in effectiveness. Alternatively, the chute's discharge opening can be narrowed to ensure the material is centered on the downstream belt conveyor. Since the material often contains large stones and other debris, narrowing the chute's discharge opening can easily cause the belt conveyor to become blocked. Utility Model Content

[0003] 1. Technical problems to be solved by the utility model

[0004] In order to solve the problems in the existing technology that the chute causes deviation of the drop point during material transfer and the narrowing of the chute discharge port easily causes blockage of the belt conveyor, the utility model provides a chute with adjustable drop point. The deviation of the belt conveyor belt is corrected by adjusting the baffle. The material passes through the adjustable baffle to play a buffering role and also reduces the wear of the guard plates on both sides of the belt conveyor guide chute below.

[0005] 2. Technical solution

[0006] In order to achieve the above-mentioned purpose, the technical solution provided by the present utility model is:

[0007] A chute with an adjustable drop point includes an adjustment device comprising an adjustment baffle, a fixed support, and an adjustment wrench.

The connecting end of the adjustment wrench is hinged to the back of the adjustment baffle. The chute plate is perforated with a retaining hole. The free end of the adjustment wrench passes through the retaining hole and engages with the retaining hole through a retaining groove on its bottom surface. When material passes through the chute, the adjustment baffle and the adjustment wrench, mounted on the inner side wall of the chute discharge port, cooperate to control the direction of the material flow, achieve precise adjustment of the drop point, and prevent the downstream belt conveyor from deviating.

[0008] According to a further technical solution, the adjustment device is a single set or at least two sets are symmetrically arranged in the chute to increase the adjustment angle range and expand the adjustment surface.

[0009] According to a further technical solution, a material blocking device is fixedly connected laterally to the inner wall of the chute above the rotating shaft to prevent the material from entering the hinged connection position and causing jamming.

[0010] According to a further technical solution, the material blocking device is an I-beam, which has high material blocking strength and long service life.

[0011] A further technical solution is that a lining is fixed on the surface of the adjusting baffle, and the lining can be made of different materials according to the material properties. The lining and the adjusting baffle are connected with countersunk bolts to increase the service life of the entire adjusting baffle.

[0012] A further technical solution is to have multiple slots arranged horizontally, which can achieve multi-level angle adjustment to adapt to different materials.
