Description

Technical Field

[0001] This utility model relates to the field of plastic engineering construction technology, specifically to a raw material paver for plastic engineering construction. Background Technology

[0002] Plastic engineering mainly includes the construction of plastic flooring and plastic running tracks. During construction, plastic granules and adhesives need to be mixed in proportion, and the raw materials are spread on the laying area. The raw materials are then flattened and smoothed to complete the final laying. The raw materials are mainly spread out by a paver during the laying process.

[0003] For example, Chinese patent document CN222557397U discloses a plastic track paver, including a frame and a mounting plate mounted on the frame; one side of the mounting plate is provided with an adjustable height paving component, and a guide plate is installed on the side of the mounting plate near the paving component; a cleaning roller is provided at the bottom of the mounting plate, and two sets of symmetrically arranged spiral blades are installed on the cleaning roller. The side of the spiral blades away from the cleaning roller is connected to a cleaning brush, and both ends of the cleaning roller are connected to a center rod. A support seat is provided at the bottom of the mounting plate to support the stable rotation of the center rod.

[0004] In the above technical solution, when the driving component drives the center rod and the vertical rod to rotate, the brush can clean one side of the junction of the two sets of spiral blades. Then, as the cleaning roller rotates, the spiral blades drive the cleaning brush to clean, which helps to clean impurities to the area near the center rod. The setting of the brush can improve the cleaning effect. At the same time, the guide plate can play a protective role in guiding the material and reduce the splashing of impurities onto the material paving area.

[0005] However, in actual use, it was found that the raw materials need to be flattened after being spread. However, in the above technical solution, the spreading and flattening of the raw materials cannot be carried out at the same time, which affects the overall laying efficiency. Furthermore, if the raw materials are flattened after being spread, they are prone to solidification during the air exposure time, which affects the final laying quality. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a raw material paver for plastic engineering construction, which can flatten the raw materials to a certain extent during the laying process.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a raw material paver for plastic engineering construction, comprising a hopper, the top of which is a material inlet, a rotatable shaft inside the hopper, two spirally distributed and symmetrically arranged dragon blades on the outer periphery of the shaft, rotatable front and rear wheels at the front and rear ends of the hopper respectively, and a pressure plate above the front wheel that can be raised and lowered following the rotation of the front wheel, the pressure plate being raised and lowered to pre-flatten the raw material during the paving process.

[0008] The present invention is further configured such that: a connecting shaft is provided on the outer side of the front end of the hopper, one end of the connecting shaft is rotatably connected to the outer wall of the hopper, and the other end extends outward as a connecting end, the front walking wheel is fixedly mounted on the outer periphery of the connecting end, a cam is provided between the front walking wheel and the outer wall of the hopper, the cam is fixedly mounted on the outer periphery of the connecting end, and the cam rotates with the connecting shaft so that the cam peak of the cam periodically contacts the surface of the pressure plate.

[0009] The present invention is further configured such that: a connecting frame integrally formed with the hopper is provided above the pressure plate, and a spring is provided between the connecting frame and the pressure plate, wherein there are multiple springs spaced apart from each other.

[0010] The present invention is further configured such that: the lower surface of the connecting frame is provided with a downwardly extending first extension tube, the connecting frame is provided with a first groove extending to the first extension tube, the upper surface of the pressure plate is provided with an upwardly extending second extension tube, the pressure plate is provided with a second groove extending to the second extension tube, and the two ends of the spring are respectively embedded in the first groove and the second groove.

[0011] The present invention is further configured such that: a guide rod is provided on the pressure plate, and a guide hole is provided on the connecting frame opposite to the guide rod; one end of the guide rod extends to the guide hole and can form a sliding fit with the guide hole.

[0012] The present invention is further configured such that: an inclined scraper is provided between the pressure plate and the hopper, one end of the scraper is a connecting part parallel to the surface of the hopper, and the other end is a leveling part parallel to the ground, the connecting part is provided with a through connecting hole, the outer wall of the hopper is provided with a threaded hole opposite to the connecting hole, and the connecting hole and the threaded hole are fixed by a locking member.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] Because of the pressure plate that can be raised and lowered as the hopper moves, the pressure plate can be raised and lowered as the front wheels rotate during the movement of the hopper. Therefore, the pressure plate can press the paved material during the descent to pre-flatten the material, which makes it easier to flatten the paved material with an electric heating plate later, thereby improving the overall construction efficiency.

[0021] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] like Figures 1 to 4As shown, this utility model discloses a raw material paver for plastic engineering construction, including a hopper 1. The top of the hopper 1 is an inlet, and the bottom is an outlet. A rotatable shaft 2 is provided inside the hopper 1. The two ends of the shaft 2 are rotatably connected to the inner wall of the hopper 1 through bearings. A motor 100 is provided on the outer periphery of the hopper 1. The output end of the motor 100 is connected to one end of the shaft 2 through a coupling. Two spirally distributed and symmetrically arranged dragon blades 3 are provided on the outer periphery of the shaft 2. Rotatable front travel wheels 4 and rear travel wheels 5 are provided at the front and rear ends of the hopper 1, respectively. A pressure plate 6 is provided above the front travel wheels 4, which can be raised and lowered with the rotation of the front travel wheels 4. The pressure plate 6 is raised and lowered to pre-press the raw material during the paving process. During paving, the raw material is poured into the hopper 1 from the inlet. As the rotating shaft 2 rotates, the raw materials are conveyed to both sides through the auger blades 3 on both sides, spreading the poured raw materials out. Under the action of gravity, the raw materials are evenly delivered from the discharge port. At this time, the workers can evenly spread the raw materials on the construction area by moving the material bin 1. During the movement of the material bin 1, the front traveling wheel 4 rotates, which drives the pressure plate 6 to rise and fall. Therefore, the pressure plate 6 can press the spread raw materials during the descent to pre-flatten them, which makes it easier to flatten the spread raw materials with the electric heating plate later, thereby improving the overall construction efficiency. Furthermore, by pre-flattening the raw materials, the air in the gaps between the raw materials can be squeezed out, thereby extending the solidification time of the raw materials and preventing it from affecting the quality of the subsequent flattening of the raw materials.

[0024] In this embodiment, the structure in which the pressure plate 6 moves up and down with the front walking wheel 4 is as follows: a connecting shaft 7 is provided on the outer side of the front end of the hopper 1. One end of the connecting shaft 7 is rotatably connected to the outer wall of the hopper 1 through a bearing, and the other end extends outward as a connecting end. The front walking wheel 4 is fixed to the outer periphery of the connecting end through a keyway sleeve. A cam 8 is provided between the front walking wheel 4 and the outer wall of the hopper 1. The cam 8 is fixed to the outer periphery of the connecting end through a keyway sleeve. When the hopper 1 is moved, the cam 8 can rotate with the rotation of the connecting shaft 7. Therefore, no additional power input is required, which effectively controls the overall manufacturing cost. Under the rotation of the cam 8, the cam peak of the cam 8 can periodically contact the surface of the pressure plate 6, thereby driving the pressure plate 6 to move up and down periodically. Therefore, during the spreading process, the pressure plate 6 can pre-press the raw material by periodically descending. In addition, the connection structure between the rear walking wheel 5 and the hopper 1 is the same as the connection structure between the front walking wheel 4 and the hopper 1, so it will not be described in detail here.

[0025] In this embodiment, in order to facilitate the self-reset of the pressure plate 6 after the cam 8 peak of the cam 8 moves away from the pressure plate 6, so that the cam 8 peak of the cam 8 can contact the pressure plate 6 again, a connecting frame 9 integrally formed with the hopper 1 is provided above the pressure plate 6. A spring 10 is provided between the connecting frame 9 and the pressure plate 6. There are multiple springs 10 and they are spaced apart from each other. In this way, when the cam 8 peak of the cam 8 contacts the pressure plate 6, it can drive the pressure plate 6 to descend to stretch the spring 10. Then, when the cam 8 peak of the cam 8 leaves the pressure plate 6, the previously stretched spring 10 can drive the pressure plate 6 to reset.

[0026] In addition, a first extension tube 11 extending downward is provided on the lower surface of the connecting frame 9, and a first groove 111 extending to the first extension tube 11 is provided on the connecting frame 9. A second extension tube 12 extending upward is provided on the upper surface of the pressure plate 6, and a second groove 121 extending to the second extension tube 12 is provided on the pressure plate 6. The two ends of the spring 10 are respectively embedded in the first groove 111 and the second groove 121. The installation space at both ends of the spring 10 can be extended by setting the first extension tube 11 and the second extension tube 12 to improve the stability of the spring 10 installation. The fixation between the two ends of the spring 10 and the first groove 111 and the second groove 121 can be fixed by pressing to form an interference fit or by welding. After the two ends of the spring 10 are respectively embedded in the first groove 111 and the second groove 121, the extension path of the spring 10 can be guided to prevent the spring 10 from tilting during the extension process.

[0027] In this embodiment, a guide rod 13 is further provided on the pressure plate 6, and a guide hole opposite to the guide rod 13 is provided on the connecting frame 9. One end of the guide rod 13 extends to the guide hole. During the lifting and lowering of the pressure plate 6, the guide rod 13 can form a sliding fit with the guide hole, thus guiding the lifting and lowering of the pressure plate 6 and ensuring the stability of the lifting and lowering of the pressure plate 6.

[0028] In this embodiment, an inclined scraper 14 is provided between the pressure plate 6 and the hopper 1. One end of the scraper 14 is a connecting part 141 parallel to the surface of the hopper 1, and the other end is a leveling part 142 parallel to the ground. The connecting part 141 is provided with a through connecting hole 1411. The outer wall of the hopper 1 is provided with a threaded hole opposite to the connecting hole 1411. The connecting hole 1411 and the threaded hole are fixed by a locking member (i.e., screw). After the raw material is sent out from the outlet, the inclined scraper 14 can move with the hopper 1 to push the sent raw material, thereby avoiding the accumulation of the sent raw material and further improving the uniformity of the raw material spreading. In addition, the setting of the leveling part 142 can also press the raw material to a certain extent, thereby improving the pre-flattening effect of the raw material. Furthermore, a clearance opening 91 is provided on the connecting frame 9, which facilitates the installation of the scraper 14 on the hopper 1.

[0029] In this embodiment, a handle 15 is provided at the rear end of the hopper 1. A sleeve 16 is provided on the side of the hopper 1 facing away from the pressure plate 6. A connecting groove is provided inside the sleeve 16. The end of the handle 15 can be inserted into the connecting groove for fixation. When it is necessary to drive the hopper 1 to move, the handle 15 makes it easier for the worker to apply force, thereby making it easier for the worker to drive the hopper 1 to move.

[0030] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
