Description

Technical Field

[0001] This utility model relates to the field of concrete pouring, and in particular to a wear-resistant concrete pouring chute. Background Technology

[0002] A chute is a specific engineering operation, typically used in drainage systems or other liquid transport pipelines. When pouring concrete, a chute is generally needed to transport the concrete. When pouring concrete, one end of the concrete needs to be placed on a pre-erected support for pouring.

[0003] When the existing chute body is erected on the support for pouring, the concrete transported from the top passes through the chute. Because the concrete contains sand and gravel, the sand and gravel will scrape and come into contact with the lower inner wall of the chute body over a long period of time. Utility Model Content

[0004] The main objective of this invention is to provide a wear-resistant concrete pouring chute, which can effectively solve the technical problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A wear-resistant concrete pouring chute includes a chute body, a first flange fixedly installed on one outer wall of the chute body, and a replacement structure fixedly installed on the inner wall of the chute body. The replacement structure includes a removal plate, hollow fixing columns fixedly installed on both sides of the upper end of the removal plate, a first screw installed inside the hollow fixing column, a reserved hole opened at the lower end of the chute body located at the lower end of the first screw, the lower end of the first screw passing through the reserved hole and a first nut fixedly installed on the outer wall of the chute body, a second flange fixedly installed on one outer wall of the chute body, and a limit plate fixedly installed on the outer wall of the removal plate near the second flange.

[0007] As a further embodiment of this utility model, a buffer structure is provided at the lower end of the chute body. The buffer structure includes two sets of fixing plates fixedly installed at the lower end of the chute body. A limit groove is opened inside the fixing plate, and a support plate is movably installed inside the limit groove. Two sets of springs are fixedly installed at the upper end of the support plate, and the upper ends of the springs are fixedly connected to the lower end of the chute body.

[0008] As a further embodiment of this utility model, two sets of second screws are fixedly provided on one side of the limiting plate, a guide block is fixedly provided at the lower end of the chute body, and the output end of the second screw passes through the guide block and a second nut is threaded on its outer wall.

[0009] As a further embodiment of this utility model, a reserved groove is provided at the lower end of one side of the second flange, and the limiting plate is located inside the reserved groove.

[0010] As a further embodiment of this utility model, the lower end of the mounting plate is arc-shaped.

[0011] As a further embodiment of this utility model, an assembly plate is provided at the lower end of both sets of fixing plates, and protrusions are fixedly provided at the front and rear ends of the upper end of the assembly plate. A groove is provided at the lower end of the fixing plate located above the protrusions, and a third screw is provided at one end of the fixing plate. The output end of the third screw passes through the protrusions and is threaded to a third nut on the outer wall of one side of the fixing plate.

[0012] As a further embodiment of this utility model, the limiting plate has a circular hole inside that corresponds to one side of the second flange.

[0013] The beneficial effects of this utility model are as follows:

[0014] By setting up a replacement structure, when concrete is transported and discharged through the inner wall of the chute body for a long time, the concrete will not directly wear down to the inner wall of the bottom end of the chute body, causing the inner wall of the chute body to become thinner. The service life of the chute body can be extended by replacing the removal plate.

[0015] By setting up a buffer structure, when the chute body is placed on the frame, the swaying force generated by concrete transportation is buffered by springs, which can prevent the lower end of the chute body from making hard contact with the frame and causing deformation of the chute body.
