Description

Technical Field

[0001] The utility model relates to the technical field of floor construction equipment, and particularly relates to a corundum spreading device. Background Art

[0002] The corundum floor is a common name for a wear-resistant hardened floor. The corundum floor has the advantages of wear resistance, compression resistance, dust reduction, hard surface, easy cleaning, economy and durability. The corundum floor material is a dry-spread floor hardener that is pre-mixed in the factory and ready to use on site. During construction, it is evenly spread on the surface of the concrete in the initial setting stage. After overall curing, it forms a dense whole and a super-hardened surface layer with the concrete floor, which is a high-performance wear-resistant floor with compression resistance, impact resistance, wear resistance, high precision and coloring. During the construction of the corundum floor, it is required that the corundum be evenly distributed. Only when the corundum is evenly distributed can a floor with uniform wear resistance and compression resistance be formed.

[0003] However, traditional corundum is usually spread manually. The uniformity of manual spreading is not controllable. Therefore, usually after manual spreading, it is necessary to level it manually for a second time. Therefore, the efficiency is low and it consumes a lot of manpower. Summary of the Utility Model

[0004] The purpose of the utility model aims to solve at least one of the technical defects described in the background art.

[0005] To this end, an object of the utility model is to propose a corundum spreading device, aiming to solve the problems of low efficiency and high manpower consumption in the traditional manual spreading method.

[0006] To achieve the above object, an embodiment of one aspect of the utility model provides a corundum spreading device, including a material box and a spreading shaft. The bottom surface of the material box is inclined, and a discharge port is opened on the lowest side of the bottom surface of the material box. Both ends of the spreading shaft are fixedly connected with rotating shafts. The spreading shaft is rotationally connected to the discharge port of the material box through the rotating shafts at both ends. A positioning block is fixedly connected to the bottom of the material box. A support shaft is fixedly connected inside the positioning block. First rollers are rotationally connected to both ends of the support shaft. The first rollers are in transmission connection with the rotating shafts. A traction frame is fixedly connected to the bottom of the material box. A connecting shaft is rotationally connected inside the traction frame. A support block is fixedly connected to the bottom end of the connecting shaft. Second rollers are rotationally connected to both sides of the support block. A traction rod is fixedly connected to the top end of the connecting shaft. Handles are fixedly connected to both sides of the traction rod.

[0007] Preferably, from any of the above solutions, the total width of the support shaft and the first rollers at both ends thereof is smaller than the width of the discharge port. When spreading, it is avoided that the first rollers roll over the surface of the previously spread corundum.

[0008] Preferably, according to any of the above solutions, L-shaped positioning rods are fixedly connected to both sides of the bottom of the material box. A baffle is slidably connected between the two L-shaped positioning rods. One side of the baffle is fixedly connected to a U-shaped rod. One side of the material box is fixedly connected to a chute. A positioning pin is slidably connected inside the chute. A plurality of positioning holes are formed on one side of the U-shaped rod. When turning, the baffle can be used to close the discharge port, thereby avoiding the problem of waste caused by the spilling of emery. Moreover, the size of the discharge port can be adjusted through the plurality of positioning holes, so as to achieve the purpose of adjusting the speed of material spreading.

[0009] Preferably, according to any of the above solutions, a fixed block is hinged to the end of the traction rod away from the handlebar. The fixed block is fixedly connected to the top of the connecting shaft, which is convenient for people of different heights to use.

[0010] Compared with the prior art, the advantages and beneficial effects of the present utility model are as follows:

[0011] 1. By pouring emery into the material box and then moving the material box by traction and rotating the spreading shaft, the emery material in the material box can be evenly spilled from the discharge port, with uniform spreading and no need for secondary leveling. Therefore, the purpose of improving efficiency and saving labor can be achieved.

[0012] 2. By making the total width of the support shaft and the two first rollers smaller than the width of the discharge port, when spreading the material, the first rollers will not roll over the edge of the previously spread emery material, so that no marks will be rolled out on the emery layer. Therefore, the spilled emery layer is flatter.

[0013] 3. By setting a baffle, when turning, the baffle is pushed by the U-shaped rod to block the discharge port, so that the emery material cannot be spilled. Therefore, the problem of material spilling and waste during the turning process is avoided. And when pulling the U-shaped rod to open the discharge port, the discharge size of the discharge port can be adjusted by inserting the positioning pin into different positioning holes. Therefore, the purpose of adjusting the feeding rate can be achieved.

[0014] 4. The traction rod is fixedly connected to the top of the connecting shaft through the fixed block, and the traction rod is hinged to the fixed block. Therefore, the traction rod can rotate, and during the rotation process, the height of the handlebar rises and falls accordingly. Therefore, it can be suitable for people of different heights to operate, improving the practicability.

[0024] The present utility model provides a carborundum spreading device.

[0025] Embodiment 1:

[0026] As Figure 1-2As shown in the figure, it includes a material bin 1 and a spreading shaft 2. The bottom surface of the material bin 1 is inclined, and a discharge port 11 is provided on the lowest side of the bottom surface of the material bin 1. Both ends of the spreading shaft 2 are fixedly connected with rotating shafts 21. The spreading shaft 2 is rotationally connected to the discharge port 11 of the material bin 1 through the rotating shafts 21 at both ends. There is a gap between the spreading shaft 2 and the side wall of the discharge port 11. The emery in the material bin 1 gathers together and will not spill from the discharge port 11. When the spreading shaft 2 rotates, it can drive the emery at the bottom to spill out from the discharge port 11. A number of bumps 22 are fixedly connected to the outer surface of the spreading shaft 2. The bumps 22 rotate with the spreading shaft 2, so as to loosen the emery at the bottom of the material bin 1, so that the emery can spill more smoothly from the discharge port 11. A positioning block 12 is fixedly connected to the bottom of the material bin 1. A support shaft 13 is fixedly connected to the inside of the positioning block 12. Both ends of the support shaft 13 are rotationally connected with first rollers 14. The first rollers 14 are drivingly connected with the rotating shafts 21. The rotation of the first rollers 14 makes the material bin 1 move, and the first rollers 14 rotate the rotating shafts 21 through transmission, so that the spreading shaft 2 rotates. Therefore, the purpose of spreading can be achieved. A towing frame 15 is fixedly connected to the bottom of the material bin 1. A connecting shaft 3 is rotationally connected to the inside of the towing frame 15. A support block 31 is fixedly connected to the bottom end of the connecting shaft 3. Second rollers 32 are rotationally connected to both sides of the support block 31. A towing rod 33 is fixedly connected to the top end of the connecting shaft 3. Handles 34 are fixedly connected to both sides of the towing rod 33. By holding the handles 34, the second rollers 32 can be pulled to roll, so as to tow the material bin 1 to move through the towing frame 15. And the connecting shaft 3 is rotationally connected to the towing frame 15, which is convenient for turning.

[0027] Embodiment 2:

[0028] As Figure 1 or Figure 3 shown, on the basis of Embodiment 1, when using this device to spread emery along a straight line and then turning the device to continue spreading adjacent to the previously spread emery, the spilled emery is adjacent to the previously spread emery. Since the total width of the support shaft 13 and the first rollers 14 at both ends thereof is smaller than the width of the discharge port 11, the first rollers 14 will not roll over the previously spread emery layer, thus avoiding the problem of rolling out marks and affecting the flatness. A transmission shaft 5 is fixedly connected to the axle center of the first roller 14. A first pulley 51 is fixedly connected to the outer surface of the transmission shaft 5. The transmission shaft 5 can extend the first pulley 51 to the outside of the material bin 1. A second pulley 52 is fixedly connected to the outer surface of the rotating shaft 21. The first pulley 51 and the second pulley 52 are drivingly connected by a belt 53. The first roller 14 rolls, and the spreading shaft 2 is driven to rotate through the belt 53.

[0029] Embodiment 3:

[0030] As Figure 2-4As shown, on the basis of Example 1 or Example 2, L-shaped positioning rods 16 are fixedly connected to both sides of the bottom of the material box 1, and a baffle 4 is slidably connected between the two L-shaped positioning rods 16. A U-shaped rod 41 is fixedly connected to one side of the baffle 4, and the baffle 4 can be pushed and pulled by the U-shaped rod 41 to open or close the discharge port 11. A slide groove 42 is fixedly connected to one side of the material box 1, and a positioning pin 43 is slidably connected inside the slide groove 42. A plurality of positioning holes 44 are provided on one side of the U-shaped rod 41. The positioning pins 43 are inserted into the positioning holes 44 to position the U-shaped rod 41, thereby preventing the baffle 4 from sliding down and closing the discharge port 11. When the positioning pins 43 are inserted into different positioning holes 44, the blocking area of ​​the baffle 4 to the discharge port 11 is different, thereby achieving the purpose of adjusting the size of the discharge port.

[0031] Embodiment 4:

[0032] like Figure 3 As shown, on the basis of the first embodiment or the second embodiment or the third embodiment, a fixing block 331 is hinged at one end of the traction rod 33 away from the handle bar 34, and the fixing block 331 is fixedly connected to the top end of the connecting shaft 3, so that the traction rod 33 can rotate. Therefore, when people of different heights operate and hold the handle bar 34 to pull, the traction rod 33 can rotate accordingly, thereby adjusting the height of the handle bar 34 to obtain corresponding lifting and lowering, so it is suitable for people of different heights.

[0033] The working principle of the utility model is as follows: when in use, the corundum is poured into the material box 1, and then the material box 1 is pulled to move by the traction rod 33, the first roller 14 rotates, driving the spreading shaft 2 to rotate, and the convex points 22 on the surface of the spreading shaft 2 loosen the corundum at the bottom of the material box 1, so that the corundum is evenly sprinkled from the discharge port 11 to the ground, thereby achieving the purpose of spreading the material. When turning, the positioning pin 43 is pushed upward, and then the U-shaped rod 41 is pushed, so that the baffle 4 blocks the discharge port 11, so that during the turning process, the first roller 14 rotates, and the corundum material will not be scattered. After the turning is completed and the position is adjusted, the U-shaped rod 41 is pulled, the positioning pin 43 is inserted into the positioning hole 44, the baffle 4 is positioned, and then the material box 1 is continued to be pulled to move, and the material can be continued to be spread.

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] 1. By pouring corundum into the material box 1, and then pulling the material box 1 to move, the spreading shaft 2 rotates, so that the corundum material in the material box 1 can be evenly scattered from the discharge port 11, and the material is evenly scattered without secondary leveling, thereby achieving the purpose of improving efficiency and saving manpower.

[0036] 2. By making the total width of the support shaft 13 and the two first rollers 14 smaller than the width of the discharge port 11, when spreading the abrasive, the first rollers 14 will not crush the edge of the previously spread emery material, so that no marks will be rolled out on the emery layer. Therefore, the spread emery layer is smoother.

[0037] 3. By setting the baffle 4, when turning, the baffle 4 is pushed by the U-shaped rod 41 to block the discharge port 11, so that the emery material cannot be spilled. Therefore, the problem of material spillage and waste during turning is avoided. And when pulling the U-shaped rod 41 to open the discharge port 11, the positioning pin 43 can adjust the discharge size of the discharge port 11 by inserting into different positioning holes 44. Therefore, the purpose of adjusting the feeding rate can be achieved.

[0038] 4. The towing bar 33 is fixedly connected to the top of the connecting shaft 3 through the fixing block 331, and the towing bar 33 is hinged to the fixing block 331. Therefore, the towing bar 33 can rotate. During the rotation process, the height of the handle bar 34 rises and falls accordingly. Therefore, it can be operated by people of different heights, improving the practicability.
