Description

Technical Field

[0001] The utility model relates to a material discharge chute with an adjustment function, belonging to the technical field of material transportation. Background Art

[0002] At present, the hopper loading system is widely used in port unloading operations. The operation process is to unload the material in the grab bucket into the hopper first. The lower end of the hopper is connected to a discharge chute, and the bottom of the discharge chute has a discharge port. By controlling the opening of the discharge port valve, the material is unloaded into the truck compartment. When the material in the compartment reaches a certain height, the discharge valve is automatically closed.

[0003] However, in actual applications, due to the long carriage, the vehicle needs to be moved several times to coordinate the loading and unloading operations, which is troublesome. In addition, the height of the unloading port must be greater than the height of the truck compartment. During the unloading process, it is very easy to cause dust to float to varying degrees, often exceeding the dust standards required by environmental protection.

[0004] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] In view of the deficiencies in the background technology, the utility model provides a discharge chute with an adjustment function, which can not only automatically adjust the discharge position to reduce the movement times of the transport vehicle, but also automatically adjust the discharge height to reduce the generation of dust.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] The discharge chute with an adjustable function comprises a main pipe, the top of which is connected to the bottom of the inner cavity of the funnel through a fixed pipe, the bottom of which is provided with a sleeve slidably connected thereto, and a feeding hopper is installed at the bottom of the sleeve;

[0008] A slewing bearing is installed between the bottom end of the fixed pipe and the top end of the main pipe. The slewing bearing is installed between an upper flange and a lower flange by bolts.

[0009] The outer wall of the sleeve is connected to the head of the second electric telescopic rod, the second electric telescopic rod is arranged in the vertical direction, and the tail of the second electric telescopic rod is fixedly connected to the outer wall of the main pipe.

[0010] Furthermore, the top of the fixed tube is fixedly connected to the bottom of the funnel, and two fixed tubes are correspondingly arranged at the bottom of each funnel.

[0011] Furthermore, the slewing bearing comprises a rotatably connected supporting inner ring and a supporting outer ring, the supporting inner ring is connected to the upper flange by bolts, and the supporting outer ring is connected to the lower flange by bolts.

[0012] Furthermore, a gear ring is fixedly installed on the outside of the supporting outer ring, the gear ring is meshed and connected with the gear on the motor output shaft, and the motor is fixed to the outside of the fixed tube.

[0013] Furthermore, a gate plate is installed inside the fixed tube, and a side end of the gate plate is connected to the first electric telescopic rod.

[0014] Furthermore, an electric jaw valve is installed in the feeding hopper.

[0015] Furthermore, the motor, the first electric telescopic rod, the second electric telescopic rod and the electric jaw valve are all connected to the PLC control module.

[0016] Furthermore, the bottom end of the fixed pipe is provided with an outer chamfer, and the top end of the main pipe is provided with an inner chamfer.

[0018] Furthermore, each sleeve is correspondingly provided with two second electric telescopic rods.

[0019] Compared with the prior art, the utility model has the following advantages after adopting the above technical solution:

[0020] The material in the hopper flows to the fixed pipe, main pipe, casing pipe and feeding hopper in sequence, and finally is discharged to the transport vehicle through the feeding hopper;

[0021] During the unloading process, the PLC control module can control the motor to start. The motor drives the main pipe, casing and feeding hopper to rotate along the slewing bearing through gear transmission, thereby automatically adjusting the unloading position and reducing the number of times the transport vehicle moves.
