Description

Technical Field

[0001] The utility model relates to the technical field of concrete processing, in particular to a premixed concrete transport trolley. Background Art

[0002] On construction sites, ready-mixed concrete is usually transported to the site by a mixer truck. This vehicle is equipped with a rotating mixing drum that keeps the concrete uniform during transportation to prevent premature setting or stratification of the concrete. However, in some cases, especially on small construction sites or when concrete needs to be transported to places that mixer trucks cannot reach directly, wheelbarrows are used to transport ready-mixed concrete.

[0003] However, when unloading concrete using a wheelbarrow, workers are required to use the handle to tip the bucket to allow the concrete to slide out, which not only wastes a certain amount of manpower, but also causes concrete to splash onto workers standing near the wheelbarrow, making it inconvenient to clean up later.

[0004] Therefore, in order to solve the defects of wasting manpower and easily spilling concrete on workers when unloading with a wheelbarrow, it is necessary to propose a wheelbarrow for transporting ready-mixed concrete. Utility Model Content

[0005] The utility model aims to provide a ready-mixed concrete transport trolley, which drives the rack to move upward through a hydraulic cylinder, and the hopper automatically dumps under the meshing action of the rack and gear, so that the concrete inside slides out without human intervention and without splashing the concrete onto the workers, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A ready-mixed concrete transport trolley, comprising a top plate, a side plate, a bottom plate, a lifting frame and a hopper, wherein the left and right ends of the hopper are symmetrically welded with fixed plates, the fixed plates are movably connected to the inner walls of the side plates through a rotating shaft, and a gear is fixedly installed on the rotating shaft;

[0008] A slide groove is provided on the inner wall of the side plate at the rear end of the rotating shaft, and the lifting frame is slidably connected with the slide groove through a slider, and a rack meshing with a gear is installed on the surface of the lifting frame.

[0009] Preferably, a motor is fixedly mounted on the lifting frame, and an output end of the motor passes through the lifting frame and is fixedly connected to a stirring rod.

[0010] Preferably, a hydraulic cylinder is fixedly mounted on the top plate, and an output end of the hydraulic cylinder passes through the top plate and is fixedly connected to a lifting frame.

[0011] Preferably, a push handle is installed on the outer wall of the side panel.

[0012] Preferably, universal wheels are installed on the lower surface of the base plate.

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

[0014] 1. This ready-mixed concrete transport trolley can stir the concrete during transportation through the motor and stirring rod installed on the lifting frame to ensure the uniformity of the concrete and prevent it from stratification or solidification during transportation;

[0015] 2. This ready-mixed concrete transport trolley drives the lifting frame upward through the hydraulic cylinder, which can not only drive the stirring rod upward to facilitate unloading, but also drive the rack upward, so that the hopper automatically dumps under the meshing action of the rack and the gear, realizing automatic unloading of concrete, reducing manpower requirements, and avoiding close contact between workers and concrete during the unloading process, reducing the risk of concrete splashing on workers, and improving operation safety.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] For technical questions on how to prevent concrete from delamination or solidification during transportation, please refer to Figure 1-Figure 2 , this embodiment provides the following technical solutions:

[0022] A ready-mixed concrete transport trolley comprises a top plate 11, a side plate 12, a bottom plate 13, a lifting frame 2 and a hopper 3. A push handle 121 is installed on the outer wall of the side plate 12, a universal wheel 131 is installed on the lower surface of the bottom plate 13, a motor 23 is fixedly installed on the lifting frame 2, an output end of the motor 23 passes through the lifting frame 2 and is fixedly connected to a stirring rod 24, a hydraulic cylinder 111 is fixedly installed on the top plate 11, and an output end of the hydraulic cylinder 111 passes through the top plate 11 and is fixedly connected to the lifting frame 2.

[0023] Specifically, during transportation, the concrete is introduced into the hopper 3 by a shovel or other equipment, and then the hydraulic cylinder 111 is started, and the hydraulic cylinder 111 drives the lifting frame 2 to move downward until the stirring rod 24 extends into the hopper 3, and then the motor 23 is started, and the motor 23 drives the stirring rod 24 to rotate, so as to stir the concrete in the hopper 3 to prevent the concrete from being stratified or solidified during transportation.

[0024] To solve the technical problem of how to realize automatic unloading of concrete by wheelbarrow, please refer to Figure 3 , this embodiment provides the following technical solutions:

[0025] Fixed plates 31 are symmetrically welded at the left and right ends of the hopper 3. The fixed plates 31 are movably connected to the inner wall of the side plate 12 through a rotating shaft 32. A gear 33 is fixedly installed on the rotating shaft 32. A slide groove 122 is opened on the inner wall of the side plate 12 at the rear end of the rotating shaft 32. The lifting frame 2 is slidably connected to the slide groove 122 through a slider 22. A rack 21 meshing with the gear 33 is installed on the surface of the lifting frame 2.

[0026] Specifically, when unloading is required, the hydraulic cylinder 111 is started to drive the lifting frame 2 to move upward. At this time, the lifting frame 2 drives the stirring rod 24 to move upward to facilitate the dumping of the hopper 3. At the same time, the lifting frame 2 also drives the rack 21 to move upward. The upward movement of the rack 21 drives the gear 33 meshing with it to rotate, so that the hopper 3 rotates automatically, which facilitates the concrete in the hopper 3 to slide out, thereby realizing automatic unloading of the concrete.

[0027] Working principle: When using the ready-mixed concrete transport trolley, firstly, the concrete is introduced into the hopper 3 through a shovel or other equipment, and the hydraulic cylinder 111 is started. The hydraulic cylinder 111 drives the lifting frame 2 and the rack 21 to move downward until the stirring rod 24 extends into the hopper 3. At this time, the gear 33 drives the hopper 3 to rotate to a horizontal state under the meshing action of the rack 21 to prevent the hopper 3 from tilting and spilling the concrete. Then the motor 23 is started to drive the stirring rod 24 to rotate, and the concrete is stirred to prevent stratification or solidification during transportation. Then the trolley is pushed manually until it is pushed to the place where unloading is required, and then the hydraulic cylinder 111 is started to drive the lifting frame 2 to move upward. The lifting frame 2 drives the stirring rod 24 and the rack 21 to move upward. The upward movement of the stirring rod 24 facilitates the unloading of the concrete, and under the meshing action of the rack 21, the gear 33 drives the hopper 3 to automatically dump until the concrete in the hopper 3 slides out, thereby realizing the automatic unloading of the concrete.
