Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a discharge hopper for construction engineering. Background Art

[0002] Construction engineering, as part of the construction project, refers to the engineering entity formed by the construction of various types of buildings and their ancillary facilities, and the installation of supporting wiring, pipelines, and equipment. Construction engineering includes factories, theaters, hotels, shops, schools, hospitals, and residences, meeting people's needs for production, living, learning, and public activities. Construction engineering is comprehensive, social, practical, technical, economic, and architecturally unified. Compared with the scope of construction engineering, the scope of construction engineering is relatively narrow, specifically referring to various types of buildings and their ancillary facilities, and the installation of supporting wiring, pipelines, and equipment. Therefore, it is also called housing construction engineering.

[0003] After searching, a Chinese patent with publication number CN219635228U discloses a material transportation device for construction projects, the technical key points of which are: it includes a base frame and a unloading mechanism; the base frame: the front side of its upper surface is rotatably connected to a construction material bucket through a rotating shaft, the front side of the lower surface of the base frame is rotatably connected to a rotating rod through a bearing, and two symmetrically distributed wheels are provided on the left and right sides of the outer arc surface of the rotating rod. Two symmetrically distributed sliding grooves are symmetrically provided on the upper end of the rear side surface of the base frame, and handrails are slidably connected in the sliding grooves. The handrails are provided with evenly distributed first threaded holes on the side away from the vertical center of the base frame. The material transportation device for construction projects can make unloading easier and more stable when unloading solid materials such as sand and stones that are relatively small and heavy for construction projects, and can effectively prevent the material transportation device for construction projects from moving during the unloading process, causing the construction materials to be scattered all over the ground.

[0004] However, the shock-absorbing mechanism in the existing technology causes the material to be easily shaken and thrown from the hopper during transportation, which can easily affect the transportation efficiency and cause material loss. In order to solve the deficiency of the lack of shock-absorbing mechanism in the existing technology, the present application drives the damping rod to contract through components such as shock-absorbing rods and shock-absorbing blocks, thereby absorbing the impact force on the outer box and achieving a shock-absorbing effect on the hopper body. Therefore, it is necessary to propose a new solution to solve this problem. Utility Model Content

[0005] In view of the above background technology, the prior art has the shortcomings and defects of lacking a shock absorbing mechanism.

[0007] Furthermore, a first shock-absorbing pad is fixedly connected to the lower surface of the hopper body, and a second shock-absorbing pad is fixedly connected to the upper surface of the outer box.

[0008] Furthermore, four support boxes are fixedly connected to the interior of the inner box, and a support column is slidably connected to the interior of each support box.

[0009] Furthermore, two reset cylinders are fixedly connected to the interior of the inner box, a reset rod is slidably connected to the interior of each reset cylinder, and a second spring is sleeved on the outer surface of each reset cylinder.

[0010] Furthermore, the outer surface of the outer box is rotatably connected to two support blocks, and a hydraulic cylinder is fixedly installed on the outer surface of each support block.

[0011] Furthermore, two sealing covers are provided above the hopper body, and one side of each sealing cover is rotatably connected to two support rods.

[0012] Furthermore, a cylinder is fixedly installed on the back of the hopper body, and the piston rod of the cylinder is fixedly connected to a two-way clamp. Both ends of the two-way clamp are rotatably connected to a driving rod, and the other end of each driving rod is rotatably connected to an active rod, and the back of the hopper body is rotatably connected to two driven rods.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. The utility model provides components such as a shock-absorbing rod and a shock-absorbing block. Through the mutual cooperation between the shock-absorbing rod and the shock-absorbing block, the shock-absorbing rod can drive the damping rod to contract through the shock-absorbing block, thereby absorbing the impact force received by the outer box, thereby achieving the effect of shock-absorbing and buffering the incoming hopper body by providing the shock-absorbing rod and the shock-absorbing block, solving the problem that the current technical solution lacks a shock-absorbing mechanism and the material is easily shaken.
