[0024] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of use of the present invention.
[0025] like Figure 1-4 As shown, the utility model proposes a small concrete transport vehicle, including a vehicle body 1 and a storage hopper 2. The storage hopper 2 is movably arranged above the vehicle body 1, a transport handle 11 is arranged at the rear of the vehicle body 1, and a driving wheel 12 is installed at the bottom of the vehicle body 1. The front end of the storage hopper 2 is rotatably installed on the vehicle body 1, and a discharge port 20 is arranged at the front end of the storage hopper 2. A baffle plate 9 is vertically slidably arranged at the discharge port 20. Slide grooves are vertically correspondingly arranged on both sides of the discharge port 20, and the baffle plate 9 is slidably arranged in the slide grooves. The baffle plate 9 is stably lifted and lowered by the cooperation with the slide groove, so that the opening and closing of the discharge port 20 is controlled. In addition, a first driving assembly for controlling the opening and closing of the baffle plate 9 is arranged on the storage hopper 2, and the first driving assembly includes a screw rod 51 and a crank 52. The screw rod 51 is vertically installed on one side of the storage hopper 2, and the crank 52 is installed on the top of the screw rod 51. A moving block 511 is threadedly sleeved on the screw rod 51, and the moving block 511 is fixedly connected to the outer wall of the baffle plate 9. When the screw rod 51 is driven to rotate by the crank 52 , the baffle plate 9 can be driven to move up and down through the moving block 511 , thereby achieving effective control of the opening and closing degree of the discharge port 20 .
[0026] The vehicle body 1 is provided with a lifting assembly for lifting the rear side of the storage hopper 2 upwards; the lifting assembly includes a second hydraulic cylinder 3, which is rotatably mounted on the vehicle body 1 below the storage hopper 2, and a piston rod of the second hydraulic cylinder 3 is tilted upward and rotatably mounted on the rear side of the bottom of the storage hopper 2. When the second hydraulic cylinder 3 is extended, the storage hopper 2 rotates around the first rotating shaft 21, so that the rear side of the storage hopper 2 is tilted up, making it easier for concrete materials to be dumped from the discharge port 20.
[0027] A scraper 4 is provided in the storage hopper 2, close to the side wall, and vertically slides along the front-back direction. The upper and side walls of the storage hopper 2 are provided with strip holes 23, and the two sides of the scraper 4 are provided with protrusions 41 that are slidably clamped in the strip holes 23. The sliding cooperation between the protrusions 41 and the strip holes 23 can improve the movement stability of the scraper 4. The storage hopper 2 is provided with a second driving component that drives the scraper 4 to move forward and backward; the second driving component includes a first hydraulic cylinder 6, which is horizontally installed on one side of the storage hopper 2, and the protrusion 41 on the scraper 4 extends through the strip hole 23 and is fixedly connected to the piston rod of the first hydraulic cylinder 6. The first hydraulic cylinder 6 drives the scraper 4 to move, so that the scraper 4 can move close to the inner wall of the storage hopper 2 toward the discharge port, thereby scraping off the concrete material adhering to the inner wall of the storage hopper 2 and accelerating the discharge efficiency of the concrete material.
[0028] The vehicle body 1 is provided with a high-pressure water pump 13 connected to an external water source, and the scraper 4 is provided with a plurality of nozzles 42 disposed toward the side wall of the storage hopper 2 and the front side wall of the scraper 4. The nozzles 42 are connected to the water outlet of the high-pressure water pump 13 through a flexible connecting pipe. After the transport vehicle is used, the high-pressure water pump 13 can pressurize the water drawn from the external water source and spray it out through the nozzles 42. With the forward and backward movement of the scraper 4, the residual concrete material adhering to the scraper 4 and the inner wall of the storage hopper 2 can be thoroughly washed away, thereby significantly improving the cleaning efficiency inside the hopper and reducing the labor intensity of the workers.
[0029] A lower hopper 7 is installed at the front end of the vehicle body 1. Fixed plates are provided on both sides of the front end of the vehicle body 1, and both sides of the storage hopper 2 are rotatably mounted on the fixed plates through the first rotating shaft 21. Both sides of the lower hopper 7 are rotatably mounted on the fixed plates through the second rotating shaft 71, and the feeding end of the rear side of the lower hopper 7 is arranged below the lower opening 20 of the storage hopper 2. The installation height of the second rotating shaft 71 is lower than the first rotating shaft 21, so that when the lower hopper 7 is turned forward, the rear end of the lower hopper 7 can abut against the bottom of the lower opening 20 of the storage hopper 2, and the concrete flowing out of the lower opening 20 is completely prevented from leaking.
[0030] A hook block 72 is fixedly provided on the side of the lower hopper 7 in front of the second rotating shaft 71. One end of the tension spring 8 is fixedly connected to the hook block 72, and the other end is fixedly connected to the fixed plate. When the hook block 72, the tension spring 8 and the second rotating shaft 71 are in the same straight line, the tension spring 8 is in the longest stretched state. When unloading, the lower hopper 7 is pulled forward to rotate so that the lower hopper 7 rotates around the second rotating shaft 71. Under the elastic force of the tension spring 8, the front end of the lower hopper 7 is tilted downward, and the rear end is effectively abutted against the bottom of the storage hopper 2. In the non-unloading state, the lower hopper 7 can be pulled upward to reset. Under the elastic force of the tension spring 8, the lower hopper 7 will stably lean against the material blocking plate 9 to prevent the lower hopper 7 from tipping over during transportation and affecting the movement of the transport vehicle.
[0031] The lower hopper 7 is a triangular design with a narrow front and a wide rear. Guide plates 73 are fixed on both sides of the lower hopper 7 to effectively convey and guide the materials so that the materials can be discharged in a centralized manner. The width between the rear ends of the two guide plates 73 is greater than the width of the storage hopper 2, so that it is more convenient for the lower hopper 7 to receive the materials from the lower opening 20 to avoid leakage.
[0032] When using the utility model, concrete material is stored in the storage hopper 2 between the scraper 4 and the baffle plate 9. After the transport vehicle moves to the construction unloading area, the unloading hopper 7 is first opened forward, and the screw 51 is rotated by the crank 52 to move the baffle plate 9 upward to open the unloading port 20, and the concrete material is unloaded through the unloading hopper 7. During this period, the action of the first hydraulic cylinder 6 and the second hydraulic cylinder 3 is coordinated to make the rear end of the storage hopper 2 tilt up, and the scraper 4 moves forward to scrape the material, so that the material in the storage hopper 2 is quickly and effectively delivered. After the transport vehicle is used, in order to prevent the residual concrete from solidifying and affecting the subsequent use, the high-pressure water pump 13 is connected to the external water source, and the scraper 4 moves forward and backward. The nozzle 42 sprays high-pressure water to thoroughly rinse the scraper 4 and the residual concrete material adhering to the inner wall of the storage hopper 2.
