AI Technical Summary
The existing trolley hopper cannot be fixed at a fixed angle during loading and unloading, which makes unloading inconvenient and makes it difficult to remove dirt during cleaning.
The system employs a worm gear transmission system, where a rocker arm drives the worm to rotate, allowing the hopper angle to be adjusted and fixed. The self-locking function of the worm gear is used for unloading and cleaning.
This design allows for adjustable and fixed angles of the hopper during unloading, reducing the workload of operators and facilitating waste removal.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of dock construction, specifically a dock construction material transport trolley. Background Technology
[0002] During the construction of the dock, a large amount of construction materials need to be transported over short distances to different areas. Currently, the angle of the hopper of the small cart cannot be kept at a certain angle when loading and unloading materials, because the cart needs to be moved slowly to unload some cement mortar. When cleaning or washing the hopper, the hopper cannot be rotated to a certain angle and fixed, so the dirt inside the hopper is not easy to leave. Utility Model Content
[0003] To overcome the above-mentioned shortcomings, this utility model provides a wharf construction material transport trolley.
[0004] The technical solution adopted by this utility model is as follows:
[0005] A wharf construction material transport trolley includes a frame with rotatably mounted casters at the four corners of the frame's bottom outer wall; a support shaft is rotatably connected between the two rear ends of the top of the frame, a worm gear is fixedly sleeved in the middle of the outer wall of the support shaft, and connecting plates are fixedly connected to the left and right outer walls of the support shaft; a hopper is located at the top of the frame, with the rear ends of the hopper's bottom fixedly connected to the tops of the two connecting plates respectively; pads are fixedly connected to the bottom of the front sides of the left and right side walls of the hopper, with the pads abutting against the top of the frame; a first fixing plate is fixedly connected between the front ends of the top of the frame; a second fixing plate is located below the support shaft, with the left and right ends of the second fixing plate... The frame is fixedly connected to the left and right sides of the rear outer wall. The bottom center of the first fixing plate protrudes, and the top center of the second fixing plate protrudes. The bottom of the worm gear has a worm. The rear end of the worm passes through the protrusion of the second fixing plate and is rotatably connected to the protrusion of the second fixing plate. The worm meshes with the worm gear. The front end of the worm is fixedly connected to one end of the connecting shaft. The other end of the connecting shaft passes through the protrusion of the first fixing plate and is rotatably connected to the protrusion of the first fixing plate. The other end of the connecting shaft passes through the outer wall of the first fixing plate and is fixedly connected to the rocker arm. The top front side of the frame is fixedly connected to the push handle.
[0006] The beneficial effects of this utility model are:
[0007] This invention utilizes a worm gear and worm transmission method. Due to the large transmission ratio of the worm gear and worm, when the rocker arm is turned to make the worm drive the worm gear to rotate, the operator only needs to apply a small force to make the hopper rotate a certain angle and keep it fixed for unloading. Moreover, this makes it easy to discharge dirt from the hopper when cleaning it, greatly reducing the labor intensity of the operator. Attached Figure Description

[0013] like Figure 1-4 As shown: A wharf construction material transport trolley includes a frame 1, with movable wheels 2 rotatably mounted on the four corners of the bottom outer wall of the frame 1; a support shaft 3 is rotatably connected between the two ends of the top rear side of the frame 1, a worm gear 4 is fixedly sleeved in the middle of the outer wall of the support shaft 3, and connecting plates 5 are fixedly connected to the left and right ends of the outer wall of the support shaft 3; a hopper 6 is located at the top of the frame 1, with the two ends of the bottom rear side of the hopper 6 respectively fixedly connected to the top of the two connecting plates 5; pads 7 are fixedly connected to the bottom of the left and right side walls of the hopper 6, and the pads 7 abut against the top of the frame 1; a fixing plate 8 is fixedly connected between the top front ends of the frame 1; a fixing plate 9 is located below the support shaft 3, with the left and right ends of the fixing plate 9 connected to the frame 1. The rear outer wall is fixedly connected to the left and right sides. The bottom center of the fixed plate 1 8 protrudes, and the top center of the fixed plate 2 9 protrudes. The bottom of the worm wheel 4 has a worm 10. The rear end of the worm 10 passes through the protrusion of the fixed plate 2 9. The rear end of the worm 10 is rotatably connected to the protrusion of the fixed plate 2 9. The worm 10 meshes with the worm wheel 4. The front end of the worm 10 is fixedly connected to one end of the connecting shaft 11. The other end of the connecting shaft 11 passes through the protrusion of the fixed plate 1 8. The other end of the connecting shaft 11 is rotatably connected to the protrusion of the fixed plate 1 8. The other end of the connecting shaft 11 passes through the outer wall of the fixed plate 1 8. The other end of the connecting shaft 11 is fixedly connected to the rocker arm 12. The top front side of the frame 1 is fixedly connected to the push handle 13.
[0014] During normal loading and transportation, the hopper 6 is in a horizontal position, and the pads 7 on the bottom front side of the left and right side walls of the hopper 6 abut against the top of the frame 1 to maintain the stable placement of the hopper 6. The trolley is moved by the push handle 13 and the moving wheels 2.
[0015] When it is necessary to unload the construction materials from hopper 6, the operator holds the push handle 13 to stabilize the trolley while simultaneously shaking the rocker arm 12. The rocker arm 12 drives the connecting shaft 11 to rotate, which in turn drives the worm gear 10 to rotate. Since the worm gear 10 meshes with the worm wheel 4, the rotation of the worm gear 10 will drive the worm wheel 4 to rotate. The worm wheel 4 is fixedly sleeved on the middle of the outer wall of the support shaft 3, and the support shaft 3 rotates accordingly. The connecting plates 5, which are fixedly connected to the outer walls of the left and right ends of the support shaft 3, will also rotate accordingly, thereby driving the hopper 6 to rotate around the support shaft 3. The hopper 6 can rotate around the support shaft 3 and can achieve a fixed angle because the worm gear 10 and the worm wheel 4 have a self-locking function, which enables unloading. In this way, when cleaning the hopper 6, the dirt can be easily discharged from the hopper 6. Figure 4 As shown: After the hopper 6 is tilted at a certain angle, it moves to the left. The trolley moves while the hopper 6 is tilted at the same angle and the material is unloaded. This is especially suitable for laying cement mortar pavement.
[0016] After the hopper 6 is rotated to a suitable angle and the construction materials are unloaded, the rocker arm 12 is rocked in the opposite direction. Through the transmission of the worm gear 10, worm wheel 4, support shaft 3 and connecting plate 5, the hopper 6 is returned to the initial horizontal position, ready for the next loading and transportation.
