[0030] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0031] Embodiment: This embodiment aims to provide a shallow circular silo wall spraying robot, whose main function is to replace manual work to spray the silo wall, and has a wide spraying area and high efficiency, which effectively speeds up the overall construction progress of the shallow circular silo.

[0032] Reference Figure 1 and Figure 2 , including: an equipment box 1, an arc frame 4, an arc rack 8 and a drive unit. There are hanging points at the four corners of the top of the equipment box 1, which are composed of a hanger 14 and a vertical plate 15. The hanger 14 is horizontally arranged on the top of the equipment box 1, and vertical plates 15 are fixed at both ends of the hanger 14. The vertical plate 15 is fixed to the top of the equipment box 1. Usually, a lifting mechanism such as a winch is set on the top of the shallow silo, and the hanging rope can be tied to the hanger 14 to suspend the equipment box 1 around the outer wall of the shallow silo. A container for storing paint and a battery for providing power output (not shown in the figure) should be placed inside the equipment box 1. A double-tube pump 13 is fixed in the center of the top of the equipment box 1, and a feed pipe is connected between the double-tube pump 13 and the paint container.

[0033] Reference Figure 2 and Figure 3Four support frames 2 are extended from the front side of the equipment box 1 toward the outer wall of the shallow circular silo. Rollers 3 are rotatably installed at the ends of the support frames 2. The rollers 3 are in rolling contact with the outer wall of the shallow circular silo, and the rolling direction of the rollers 3 is consistent with the axial direction of the shallow circular silo. The ends of the support frames 2 are inclined toward the silo wall, and the inclined sections of the support frames 2 are kept perpendicular to the silo wall. This ensures that the rollers 3 can fully contact the silo wall during rolling, thereby ensuring that the equipment box 1 suspended in the air can stably move up and down.

[0034] Reference Figure 1 , Figure 3 and Figure 5 The arc frame 4 is centrally fixed to the top center of the equipment box 1. Specifically, a through hole 20 is provided in the middle of the arc frame 4 for installing a bolt 16, and the arc frame 4 is fixed to the box wall at the top of the equipment box 1 by the bolt 16. This method is convenient for replacing the arc frame 4 at a later time. Both ends of the arc frame 4 extend along the circumferential direction of the shallow circular warehouse, which means that the contour arc of the arc frame 4 and the warehouse wall of the shallow circular warehouse are the same; both ends of the arc frame 4 are internally provided with a sliding cavity 5 for accommodating an arc-shaped rack 8, and the upper surface of the arc frame 4 is provided with an anti-slip channel 6 consistent with the extension direction of the sliding cavity 5. At the same time, a strip notch 7 corresponding to the sliding cavity 5 is centrally provided on the front and rear sides of the arc frame 4, one end of the strip notch 7 is aligned with one end of the anti-slip channel 6, and the other end of the strip notch 7 extends to be flush with the end of the arc frame 4.

[0035] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5, arc-shaped racks 8 are provided in the two sliding cavities 5, the arc-shaped racks 8 are matched with the sliding cavities 5, and the extension direction of the arc-shaped racks 8 is consistent with the arc-shaped frame 4, and a pair of nozzles 9 are protruded from the front side of the arc-shaped racks 8 toward the outer wall of the shallow round warehouse, and the two nozzles 9 are distributed at both ends of the arc-shaped racks 8, and the ends of the nozzles 9 will not exceed the ends of the support frame 2. This setting is to avoid the nozzles 9 from touching the warehouse wall of the shallow round warehouse. A flow channel (not shown in the figure) connecting the two nozzles 9 is provided inside the arc-shaped racks 8, and teeth 10 are provided on the rear side of the arc-shaped racks 8, wherein the nozzles 9 pass through the strip-shaped notch 7 on the front side of the arc-shaped frame 4, and the teeth 10 pass through the strip-shaped notch 7 on the rear side of the arc-shaped frame 4. A hollow limiting The upper end of the limit column 11 passes through the anti-slip channel 6 and protrudes outward. The limit column 11 is connected to the adjacent nozzle 9. The protruding part of the limit column 11 is for the convenience of docking with the guide tube 12. In actual use, the discharge end of the guide tube 12 is docked with the protruding part of the limit column 11, and the feed end of the guide tube 12 is docked with the discharge port of the double-tube pump 13. In this way, the paint can enter the cavity of the limit column 11 from the guide tube 12 under the pressure of the double-tube pump 13, and then enter the nozzle 9 and finally be sprayed out through the nozzle 9. Another main function of the limit column 11 is to prevent the arc rack 8 from falling off from the sliding cavity 5, that is, to limit the maximum moving distance of the limit column 11 by the anti-slip channel 6, thereby limiting the maximum moving distance of the arc rack 8 in the sliding cavity 5.

[0036] Reference Figure 1 and Figure 3 The driving unit includes a gear 17 and a motor 18. Gears 17 are provided on the rear sides of the left and right sections of the arc frame 4. The two gears 17 are meshed with the teeth 10 on the rear sides of the corresponding arc rack 8. The motor 18 is arranged below the gear 17 and drives the gear 17 to rotate through the rotating shaft of the motor 18. The motor 18 is fixed on a support plate 19, and the support plate 19 is welded and fixed to the side of the equipment box 1.

[0037] In this embodiment, the length of the material guide tube 12 is not less than the length of the sliding cavity 5 to accommodate the sliding of the arc-shaped rack 8 in the sliding cavity 5. The shape of the material guide tube 12 can be set to a spiral shape for easier storage.

[0038] In this embodiment, the interval between the two nozzles 9 on the two arc-shaped racks 8 near the middle of the arc-shaped frame 4 should be reasonably controlled. Although the paint sprayed from the nozzles 9 is in a mist form and has a certain coverage range, it is also necessary to ensure that the warehouse wall corresponding to the interval between the two nozzles 9 can be completely covered by the paint.

[0039] In actual use, the equipment box 1 is first suspended to the specified position of the outer wall of the shallow circular silo by a winch to ensure that the four rollers 3 are in contact with the outer wall of the shallow circular silo, and then the double-tube pump 13 and the motor 18 are started at the same time. It should be noted that the rotation directions of the gears 17 driven by the two motors 18 must be opposite, that is, the sliding directions of the two arc-shaped racks 8 are both toward the outside of the sliding cavity 5. While the arc-shaped racks 8 slide, the two nozzles 9 on the front side also slide synchronously and spray paint toward the outer wall of the shallow circular silo, so as to expand the area of ​​paint spraying. As the equipment box 1 moves downward, the two arc-shaped racks 8 can reciprocate in this way to spray the paint evenly on the outer wall of the shallow circular silo.

[0040] The spraying robot provided in this embodiment can completely replace manual labor, greatly saving labor costs. At the same time, this equipment is mainly used for spraying walls with circular contours. It has a wide spraying area, high efficiency, and short time consumption, and can effectively speed up the overall construction progress of the shallow circular silo.

[0041] It should be understood that the above description is merely exemplary and the embodiments of the present application do not limit this.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are within the scope of protection of the pending claims of the present invention.
