[0031] A scraper device for lime powder production and transportation, for example Figure 1-10As shown: it includes a horizontally arranged conveying mechanism, which includes a driving assembly and a support frame 1. A driving shaft and a driven shaft are rotatably connected in the support frame 1 through a bearing. A driving roller 28 is fixedly sleeved on the surface of the driving shaft, and a driven roller 29 is fixedly sleeved on the surface of the driven shaft. A conveyor belt 2 is sleeved on the surfaces of the driving roller 28 and the driven roller 29. The driving assembly includes a motor 27. One end of the driving shaft passes through the support frame 1 and is connected to the output end of the motor 27 through a belt, a pulley or a chain or a sprocket. The support frame 1 is supported on the ground through supporting legs. The bottom of the support frame 1 is provided with inwardly concave fitting grooves 4 on both sides of the conveyor belt 2. Fitting plates 5 are movably installed in the fitting grooves 4. A locking mechanism is provided between the fitting plate 5 and the support frame 1. It also includes a collecting box 3 arranged at the bottom of the conveyor belt 2. The two ends of the top of the collecting box 3 are fixedly connected to the two fitting plates 5 respectively. A scraper 25 is provided in the collecting box 3.

[0032] In this embodiment, an opening is provided at the bottom of the support frame 1 near the conveyor belt 2, and the opening extends from the bottom of the interlocking plate 5 and is fixedly connected to the top of the side wall of the collecting box 3; the collecting box 3 can be a plastic box made of transparent material to hold the collected lime powder, which is convenient for the staff to observe whether it is full.

[0033] A rectangular groove 6 which is recessed inwardly is formed on the bottom end surface of the engaging plate 5 in the vertical direction. The locking mechanism includes a pressing plate 7 which is movably inserted into the rectangular groove 6. A locking mechanism is provided on one side of the pressing plate 7. The locking mechanism is used to abut and cooperate with the pressing plate 7 so that the locking mechanism is clamped and fixed between the rectangular groove 6 and the side wall of the engaging groove 4.

[0034] A locking groove 10 is provided on the side wall of the fitting groove 4, and a notch 12 is provided on the side wall of the rectangular groove 6. When the fitting plate 5 is completely fitted into the fitting groove 4, the notch 12 is just connected to the locking groove 10. The locking mechanism includes a locking block 11 and a second elastic mechanism. The locking block 11 is located at the notch 12 in the rectangular groove 6 and can slide outward of the notch 12. One side of the locking block 11 is installed on the inner wall of the fitting plate 5 through the second elastic mechanism. When the locking groove 10 is connected to the notch 12, the pressing plate 7 squeezes the locking block 11 and abuts against the locking block 11, so that the locking block 11 passes through the notch 12 and is locked into the locking groove 10, thereby locking and fixing the fitting plate 5 and the door body.

[0035] In this embodiment, the side wall of the rectangular groove 6 is recessed inward to provide a connecting groove 13, which is located at the notch 12 of the rectangular groove 6 and is connected to the notch 12, and the locking block 11 is located in the connecting groove 13 and can slide horizontally toward the outside of the notch 12 under the action of the second elastic mechanism. When the engaging plate 5 is fully engaged in the engaging groove 4, the notch 12 is connected to the engaging groove 10. At this time, the pressing plate 7 can be pressed into the rectangular groove 6, and the pressing plate 7 squeezes the locking block 11 and presses against the locking block 11, so that a part of the locking block 11 is embedded in the locking groove 10 and the other part is located in the notch 12, and the engaging plate 5 and the support frame 1 are limited in the vertical direction, so that the engaging plate 5 and the support frame 1 are connected and fixed, and the installation of the collection box 3 is completed, and the connection stability between the collection box 3 and the support frame 1 is high.

[0036] A movable groove 16 for engaging with the locking block 11 is provided on one side of the pressing plate 7. When the locking block 11 is locked in the locking groove 10, the movable groove 16 is located below the locking block 11. The second elastic mechanism includes a second limiting column 14 fixedly installed on the inner wall of the interlocking plate 5 in the horizontal direction. A tension spring 15 is movably sleeved on the surface of the second limiting column 14. The two ends of the tension spring 15 are respectively fixedly connected to the inner wall of the interlocking plate 5 and the locking block 11. The tension spring 15 is located on the inner side of the pressing plate 7. The top and bottom of the locking block 11 on one side close to the tension spring 15 are respectively provided with extrusion slopes for extrusion with the pressing plate 7.

[0037] In the above embodiment, in order to facilitate the disassembly of the collection box 3, a movable groove 16 is provided. When disassembly is required, the pressing plate 7 is pressed inward until the movable groove 16 is aligned with the notch 12 of the rectangular groove 6. The positioning block 11 leaves the positioning groove 10 and is embedded in the movable groove 16 under the action of the tension spring 15. The restriction of the interlocking plate 5 and the support frame 1 by the positioning block 11 is released, and the collection box 3 can be disassembled. The disassembly is easy, convenient and quick. The tension spring 15 is located in the connecting groove 13 to avoid interference with the pressing plate 7. When no external force is applied, the positioning block 11 is located in the rectangular groove 6 and does not extend out of the notch 12 under the action of the tension spring 15. The extrusion bevel is convenient. Under the elastic action of the tension spring 15, the pressing plate 7 can control the position of the movable positioning block 11 through the extrusion bevel, squeeze the positioning block 11 into the positioning groove 10, and avoid the positioning block 11 from being stuck in the rectangular groove 6. When the pressing plate 7 squeezes the positioning block 11 into the positioning groove 10, the tension spring 15 is pulled. The spring 15 is in a stretched state. During subsequent disassembly, the pressing plate 7 continues to press inward until the moving groove 16 is aligned with the locking block 11. Under the tension of the tension spring 15, the locking block 11 moves into the moving groove 16. By providing a second limiting column 14 inside the tension spring 15, the moving distance of the locking block 11 can be limited. The second limiting column 14 can prevent the locking block 11 from being too close to the interlocking plate 5 under the control of the tension spring 15, which is not conducive to the pressing plate 7 pushing the locking block 11 into the locking groove 10 by squeezing the inclined surface.

[0038] A first elastic mechanism is arranged between the top of the pressing plate 7 and the inner wall of the rectangular groove 6. The first elastic mechanism includes a first limiting column 8 fixedly installed on the inner wall of the rectangular groove 6 and a return spring 9 for being sleeved on the outside of the first limiting column 8. The bottom end of the return spring 9 is fixedly connected to the top of the pressing plate 7.

[0039] In this embodiment, the top end of the reset spring 9 is used to abut against the inner wall of the rectangular groove 6. After the locking block 11 is inserted into the locking groove 10 and installed in place, the reset spring 9 can correct the flatness of the pressing plate 7 so that the bottom of the pressing plate 7 is flush with the bottom of the interlocking plate 5. By setting a first limiting column 8 inside the reset spring 9, the moving distance of the pressing plate 7 can be limited, which is convenient for the user to limit the position through the first limiting column 8. When the bottom is pressed, the locking block 11 can be directly connected to the position of the moving groove 16.

[0040] Adjustment mechanisms are symmetrically arranged at both ends of the bottom of the scraper 25, and the adjustment mechanism includes a fixed plate 17 fixed to the inner wall of the collecting box 3, a connecting block 20 is arranged on one side of the fixed plate 17, and a fixing piece is arranged between the fixed plate 17 and the connecting block 20, and the fixing piece includes a screw 18 and a nut 19. The fixed plate 17 is provided with a long strip groove 21 along the vertical direction for the screw 18 to pass through and the fixing position of the screw 18 is adjustable. One end of the screw 18 is fixedly connected to the connecting block 20, and the other end passes through the long strip groove 21 and cooperates with the nut 19, so as to lock and fix the connecting block 20 and the fixed plate 17.

[0041] The scraper 25 is installed on the top of the connecting block 20, and a mounting rod 23 is arranged between the connecting block 20 and the scraper 25. A sleeve 22 is movably sleeved on the top of the mounting rod 23. The top of the sleeve 22 is closed and fixedly connected to the bottom of the scraper 25. A compression spring 24 is sleeved on the surface of the mounting rod 23. The top of the compression spring 24 is fixedly connected to the bottom end of the sleeve 22, and the bottom end is fixedly connected to the top of the connecting block 20.

[0042] In the above embodiment, by setting the mounting rod 23, the sleeve 22 and the compression spring 24, during the process of the conveyor belt 2 rotating and conveying the lime powder, the scraper 25 abuts against the outer side of the conveyor belt 2 and slides relative to the conveyor belt 2, and the scraper 25 scrapes off the lime powder adhering to the conveyor belt 2, and the thickness of the residual lime powder is continuously reduced. The compression spring 24 is released and pushes the scraper 25 toward the conveyor belt 2, so that the scraper 25 always keeps in contact with the outer side of the conveyor belt 2, thereby improving the cleanliness of the scraper 25 cleaning the residual lime powder, reducing the influence of the residual lime powder on the conveying of the lime powder, and achieving the purpose of improving the conveying effect of the lime powder. At the same time, by tightening or loosening the nut 19 and moving the position of the screw 18, the height of the connecting block 20 and the scraper 25 can be adjusted, and the tightness of the scraper 25 abutting against the outer side of the conveyor belt 2 can be adjusted, and it can be applied to conveyor belts 2 of different thicknesses.

[0043] The collecting box 3 is symmetrically provided with handles 26 on the side walls on both sides of the conveyor belt 2. By holding the handles 26, the collecting box 3 can be easily installed and removed from the supporting frame 1, and the collecting box 3 can also be easily moved.

[0044] The working principle of this embodiment is as follows:

[0045] When the collecting box 3 is full of lime powder and the staff needs to disassemble the collecting box 3, only two staff members need to use tools or hands to squeeze the pressing plates 7 on both sides of the conveyor belt 2 upward at the same time, and the reset spring 9 will contact the pressing plate 7 with the first limiting column 8 under the elastic action. At this time, the movable groove 16, the notch 12, and the locking groove 10 are connected, and the locking block 11 moves to the inside of the movable groove 16 under the tension of the tension spring 15 and is embedded in the movable groove 16. Since there is no locking block 11 locked in the locking groove 10, the interlocking plate 5 and the collecting box 3 will fall out of the interlocking groove 4 directly under the action of gravity, completing the disassembly of the collecting box 3. The staff member holds the handle 26 with his other hand, and then lifts the collecting box 3 away to recycle the lime powder collected inside it to avoid wasting resources.

[0046] If the collection box 3 needs to be installed, lift the collection box 3 to the bottom of the conveyor belt 2, and at the same time embed the two engaging plates 5 into the engaging grooves 4. When the engaging plates 5 are embedded in place, the notches 12 of the rectangular groove 6 are aligned with the positioning grooves 10, and then the pressing plate 7 is inserted upward from the bottom of the rectangular groove 6. The pressing plate 7 squeezes the extrusion slope below the positioning block 11, so that the positioning block 11 is inserted into the positioning groove 10, and the engaging plate 5 and the door body are locked and fixed. At this time, continue to press the pressing plate 7 down until the reset spring 9 is sleeved on the first limiting column 8 and abuts against the inner wall of the rectangular groove 6. The reset spring 9 corrects the bottom of the pressing plate 7 so that the bottom of the pressing plate 7 is flush with the engaging plate 5, and the installation of the collection box 3 is completed.

[0047] The scraping device for lime powder production and transportation provided by the utility model has an ingenious structure and is easy to use. The installation and disassembly of the collecting box 3 are convenient and quick, and the connection between the collecting box 3 and the supporting frame 1 is stable and reliable. The cleaned lime powder is collected by the collecting box 3, which can avoid the problem that the lime powder is difficult to clean after falling on the ground, and effectively reduces the workload of the staff. At the same time, when the collecting box 3 is installed in place, the top of the collecting box 3 is close to the conveyor belt 2, so as to avoid dust when the scraper 25 scrapes the lime powder; the scraper 25 is pre-pressed on the outer side of the conveyor belt 2 under the action of the compression spring 24, so that the scraper 25 always keeps in contact with the outer side of the conveyor belt 2, thereby improving the cleanliness of the scraper 25 for cleaning the residual lime powder, reducing the influence of the residual lime powder on the lime powder transportation, and achieving the purpose of improving the lime powder transportation effect.
