Description

Technical Field

[0001] This application relates to the technical field of material transfer devices, and in particular, to a material transfer device for building construction. Background Art

[0002] At present, the construction materials for earthwork subgrades are mostly soil blocks, stone blocks, concrete, etc. During the construction process, the piled materials need to be transferred to the construction site. The existing transfer devices used at the construction site are mostly two-wheeled wheelbarrows. Although the structure is simple, the unloading is rather troublesome. The user needs to hold the push handle and turn it up by more than 90 degrees so that the materials can slide out of the wheelbarrow. The labor intensity of unloading is extremely high. Sometimes, it can be seen that some users directly lift the wheelbarrow forcefully at the unloading point to turn it over completely to pour out the materials. The push handle of the wheelbarrow is easy to hit people, and the overturned wheelbarrow is easy to tilt and hit the nearby personnel, which is relatively dangerous and inconvenient to use.

[0003] Chinese Patent with application number CN201822037154.4 discloses a material transfer device for earthwork subgrade construction. The second telescopic motor drives the pushing member on the second drive shaft to move downward, so that the pushing member drives the left side of the placement box to move upward, causing the placement box to tilt, thus facilitating the removal of materials.

[0004] However, the above disclosed solution has the following deficiencies: Just tilting the placement box cannot completely pour out the transferred materials. It is not enough to just facilitate the removal. At the construction site, it is impossible to wait until the materials in the wheelbarrow are used up before pulling the next cart. Instead, the piled materials need to be continuously transferred to the construction point. Therefore, the materials must be completely poured out, which results in the disclosed structure being unable to adapt to the fast-paced transfer environment. Summary of the Invention

[0005] In order to improve the unloading efficiency of the material transfer device for building construction, this application provides a material transfer device for building construction.

[0006] The material transfer device for building construction provided by this application adopts the following technical solution: A material transfer device for building construction, including a chassis, the chassis is horizontally arranged, rollers are provided at the bottom of the chassis, a transfer hopper is arranged on the chassis, the direction of travel of the chassis and the transfer hopper is set as the front, a push handle is fixed at the rear of the chassis, a hydraulic cylinder is hinged on one side of the chassis near the rear, the movable end of the hydraulic cylinder is inclined towards the front of the transfer hopper, and the movable end of the hydraulic cylinder is hinged to the transfer hopper. A rotating shaft is rotatably arranged on one side of the chassis near the front. The transfer hopper includes side plates and a bottom plate, the bottom plate is fixed to the rotating shaft, the transfer hopper rotates relative to the chassis, there are multiple side plates, which are respectively set as a front side plate, side side plates and a rear side plate. The front side plate slides relative to the side side plates, and the sliding direction of the front side plate is along the direction of approaching or departing from the bottom plate. The side side plates and the rear side plate are respectively fixed to the bottom plate. A sliding assembly for driving the front side plate to slide is arranged on the chassis.

[0007] By adopting the above technical solutions, in the transfer device of the present application, after loading building construction materials into the transfer hopper, the push handle is pushed to transport the chassis and the transfer hopper to the required position, and then the hydraulic cylinder is started. The hydraulic cylinder jacks up the rear end of the transfer hopper, so that the rear end of the transfer hopper gradually rises. At the same time, the front rotating shaft of the transfer hopper rotates relative to the chassis, and the front side plate of the transfer hopper slides upward relative to the side side plates. In this way, the building construction materials in the transfer hopper will slide out and fall from the front side plate of the transfer hopper under the action of gravity. In this way, it can replace manual unloading of materials from the transfer hopper, achieving the purpose of convenience and high efficiency.

[0008] Optionally, a support frame is arranged on the chassis. The support frame includes a slide rail, a slider, a support rod and a slide bar. The slide rail is fixed to the chassis, and the fixed direction of the slide rail is along the traveling direction of the chassis. The slider slides in the slide rail along the length direction of the slide rail. The support rod is hinged to one end of the slide rail near the hydraulic cylinder. One end of the slide bar is hinged and slides with the support rod, and the other end is hinged to the slider. When the hydraulic cylinder raises one end of the transfer hopper, the slider is limited by the slide rail. At this time, a triangular support is formed among the slide rail, the support rod and the slide bar.

[0009] By adopting the above technical solutions, while the hydraulic cylinder supports one end of the transfer hopper to rise, the end of the support rod hinged to the transfer hopper also lifts upward, simultaneously driving one end of the slide bar hinged to the support rod, and the other end drives the slider to slide in the slide rail. When the slider is limited by the slide rail, the slide rail, the support rod and the slide bar form a triangular support, which can increase the stability when the hydraulic cylinder raises the transfer hopper for unloading.

[0010] Optionally, a plurality of convex blocks are fixedly arranged at intervals along the length direction on both sides inside the slide rail. The cross section of the convex block is set as a right triangle, and the inclined surface faces the side of the rear side plate. Spring blocks are arranged on both sides of the slider. When the slider moves towards the hydraulic cylinder direction, the spring blocks are limited by the convex blocks. A chute for releasing the limit of the slider is opened on the side wall of the slide rail.

[0011] By adopting the above technical solution, when the slider gradually moves towards the hydraulic cylinder driven by the sliding rod, the spring blocks on both sides of the slider respectively abut against the inclined surfaces of the convex blocks. At this time, the convex blocks can achieve one-way limit for the slider. When it is necessary to release the limit of the slider, it only needs to slide the slider through the chute to the starting position of the slide rail.

[0012] Optionally, an extension plate is vertically arranged on the chassis. The extension plate is vertically arranged in front of the front side plate. A rotating rod is fixed on the extension plate. The rotating rod rotates relative to the chassis, and the rotating direction of the extension plate faces the ground.

[0013] By adopting the above technical solution, when the construction materials in the transfer hopper are unloaded, while the front side plate rises, the extension plate rotates towards the ground. In this way, the construction materials in the transfer hopper pass through the extension plate and then fall on the ground, which can reduce the damage of materials such as bricks.

[0014] Optionally, a motor is fixed on the chassis. A first rotating tooth is fixed on the motor shaft of the motor. A second rotating tooth is fixed on the rotating rod. The first rotating tooth and the second rotating tooth are meshed. The sliding assembly includes a rack, a first gear, a second gear and a transmission gear set. The rack is fixed to the front side plate. The first gear is meshed with the rack. The second gear is meshed with the second rotating tooth. The transmission gear set is respectively in transmission connection with the first gear and the second gear.

[0015] By adopting the above technical solution, when the rear of the transfer hopper rises, the motor starts to drive the first rotating tooth to rotate. The first rotating tooth is meshed with the second rotating tooth to drive the extension plate to tilt towards the ground. At the same time, the second gear rotates, and drives the first gear to rotate through the transmission gear set. The first gear is meshed with the rack to drive the front side plate to rise, so as to facilitate the dumping of construction materials from the front side plate.

[0016] Optionally, a push plate is vertically arranged in the transfer hopper. Before the transfer hopper is filled with building materials, the push plate is arranged on one side of the rear side plate. The bottom of the push plate abuts against the bottom plate. A driving assembly for driving the push plate to slide is arranged in the transfer hopper.

[0017] By adopting the above technical solution, when the transfer hopper is unloading, if construction materials such as sand and gravel are piled up and adhered and do not fall automatically, the push plate can be driven to scrape the residual construction materials in the transfer hopper, improving the transfer efficiency.

[0018] Optionally, the driving assembly includes a screw rod and a guide rod. The screw rod is rotatably connected to the side plate. The guide rod is fixed on the side plate opposite to the screw rod, and the guide rod is arranged in parallel with the screw rod. One end of the push plate is threadedly connected to the screw rod, and the other end is slidably connected to the guide rod.

[0019] By adopting the above technical solution, when the screw rotates, while the push plate moves in a threaded motion with the screw, under the guiding and limiting action of the guiding rod, it can move towards the direction of the front side plate, and at the same time scrape the residual construction materials in the transfer hopper.

[0020] Optionally, a driven gear is fixed on the screw, and a driving gear is rotatably connected to the outside of the side side plate. The driving gear meshes with the driven gear, and a turning handle is fixed on the driving gear. The direction of the rotation axis of the turning handle is along the direction parallel to the bottom plate.

[0021] By adopting the above technical solution, when it is necessary to drive the push plate to move, rotate the turning handle. The turning handle drives the driving gear to rotate. The driving gear meshes with the driven gear, driving the driven gear to rotate, and then driving the screw to rotate. The screw moves in a threaded motion with the push plate. Under the guiding and limiting action of the guiding rod, the push plate can move towards the front side plate.

[0022] Optionally, a rotating roller is rotatably connected to the bottom of the push plate. The direction of the rotation axis of the rotating roller is along the direction perpendicular to the traveling direction of the chassis. A plurality of convex teeth are fixedly arranged at intervals along the circumferential direction on the rotating roller.

[0023] By adopting the above technical solution, the rotating roller can increase the smoothness when the push plate moves, and the convex teeth on the rotating roller can also prevent the push plate from being stuck by sand and gravel, etc.

[0024] Optionally, a footrest is fixed at one end of the chassis close to the push handle.

[0025] By adopting the above technical solution, when the rear of the transfer hopper rises to dump the construction materials, the construction worker can hold the push handle and step on the footrest to increase the stability of the chassis and the transfer hopper.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. After loading the construction materials in the transfer hopper, push the push handle to transport the chassis and the transfer hopper to the required position. Then hold the push handle and step on the footrest, and start the hydraulic cylinder to lift the rear of the transfer hopper. At the same time, the support frame at the bottom of the transfer hopper provides support for the transfer hopper, and the front side plate of the transfer hopper rises. In this way, the unloading work of the construction materials can be carried out more quickly and efficiently; 2. If some construction materials such as sand or gravel still adhere to the inside of the transfer hopper after the transfer hopper is tilted, rotate the turning handle. The driving gear rotates to drive the driven gear to rotate, so that the screw rotates. The screw moves in a threaded motion with the push plate, driving the push plate along the length direction of the bottom plate of the transfer hopper to scrape the adhered construction materials in the transfer hopper, improving the transfer efficiency of the construction materials.

When the slider 42 slides in the slide rail 41, the spring block 421 abuts against the inclined surface of the bump 411. At this time, the spring block 421 compresses towards the slider 42 until the spring block 421 slides off the inclined surface of the bump 411, and the spring block 421 can be limited by the bump 411.

[0036] The support rod 43 is hinged to one end of the slide rail 41 close to the hydraulic cylinder 13.

A chute 412 is horizontally opened on the side wall of the slide rail 41. The chute 412 is opened above the bump 411. When the slider 42 slides to the position of the outermost bump 411 for limitation, the slider 42 abuts against the vertical plate 46, and the spring 45 compresses. At this time, when the hydraulic cylinder 13 further lifts the transfer hopper 2, the slider 42 moves up to the height of the chute 412 and slides along the chute 412 to the initial position under the push of the vertical plate 46, and the transfer hopper 2 can fall and return to the horizontal state.

By turning the turning handle 75, the driving gear 74 drives the driven gear 73 to rotate, so that the screw rod 71 rotates. The pushing plate 6 moves in a threaded manner with the screw rod 71, and at the same time, under the guiding and limiting action of the guiding rod 72, the pushing plate 6 moves towards the front side plate 211, facilitating the scraping of construction materials such as sand and gravel adhered and fixed in the transfer hopper 2, and improving the loading and unloading efficiency.

[0041] The implementation principle of the material transfer device for building construction in the embodiment of the present application is as follows: At the construction site, first load the construction materials into the transfer hopper 2, then push the push handle 12 to push the chassis 1 and the transfer hopper 2 to the required position, and then start the hydraulic cylinder 13.
