[0025] The following further describes the utility model with reference to the drawings.
[0026] As Figures 1 to 9As shown in the figure, a conveyor belt 2 is provided inside a frame 1. A horizontal dust collection pipe 3 is provided inside the conveyor belt 2. One end of the horizontal dust collection pipe 3 is provided with a suction port 5. An inlet 4 is provided at one end of the conveyor belt 2 away from the suction port 5. A movable pipe 7 is connected to the inlet 4 through a connecting flange 6. The left and right sides of the movable pipe 7 are respectively connected to a movable track 9 through a sliding assembly 8. The left and right movable tracks 9 are respectively fixed on the left and right sides of the frame 1. The conveyor belt 2 and the movable pipe 7 move along the movable track 9, and at the same time, the suction port 5 performs dust collection operations to complete mobile dust collection.
[0027] A feed guiding plate 10 is provided on one side of the inlet 4, and an outlet guiding plate 11 is provided on one side of the suction port 5. The feed guiding plate 10 is connected to the movable pipe 7 and moves together with the conveyor belt 2. The outlet guiding plate 11 is fixed at the suction port 5 of the outlet, achieving the shortest air flow path and reducing pressure loss. The actual working air circuit is between the feed guiding plate 10 and the outlet guiding plate 11.
[0028] The horizontal dust collection pipe 3 is selected as a sheet metal bending part, and the lower end is an open structure. The opening at the lower end is attached to the surface of the conveyor belt 2.
[0029] A belt bracket 13 is provided at the lower end of the conveyor belt (2). The conveyor belt (2) is located between the lower end of the horizontal dust collection pipe (3) and the belt bracket 13. Bending sections one 28 are respectively provided on the left and right sides of the lower end of the horizontal dust collection pipe 3, and bending sections two 27 are respectively provided on the left and right sides of the upper end of the belt bracket 13. Rounded edge structures 12 protruding from the left and right sides of the conveyor belt 2 are provided, and the rounded edge structures 12 are stuck between the bending sections one 28 and the bending sections two 27. When negative pressure is generated in the horizontal dust collection pipe 3, the conveyor belt 2 is tightened under atmospheric pressure, and the edge of the conveyor belt 2 will closely adhere to the horizontal dust collection pipe 3, thus ensuring the dust collection sealing performance.
[0030] A scraper one 14 is provided at the bent part of the lower end of the horizontal dust collection pipe 3. An inclined scraper two 15 is provided below the scraper one 14. The scraper one 14 and the scraper two 15 respectively abut against the upper and lower surfaces of the conveyor belt 2. The scraper one 14 and the scraper two 15 cooperate with each other. On the one hand, the sealing performance is enhanced, and on the other hand, it can prevent dust from escaping from the horizontal dust collection pipe 3.
[0031] A pressure sensor 16 is provided inside the horizontal dust collection pipe 3. The pressure sensor 16 is located outside the feed guiding plate 10. It can not only monitor the system negative pressure but also will not be worn by high-speed dust-containing air.
[0032] An inspection door 17 is provided on the side of the frame 1 for replacing the scraper and adjusting the guiding plate.
[0033] The conveyor belt 2 is sleeved on a tensioning roller 24 and a driving roller 25 arranged in parallel.
[0034] The lower end of the movable pipe 7 is externally connected to a moving mechanism, and a belt driving mechanism 23 is provided on one side of the conveyor belt 2. In specific use, the utility model can adopt an active driving mode or a passive traction mode. In the active driving mode, the belt conveying mechanism 23 drives the conveyor belt 2 to move. This mode is applicable when the moving head moves a large distance, or when the loader does not have enough additional power to pull the moving feeding pipe. In the passive traction mode, the movable pipe 7 is driven to move by an externally connected loader moving mechanism. When the movable pipe 7 moves within a small stroke, the length of the horizontal dust collecting pipe 3 is short, and the belt driving mechanism 23 is no longer required. The truck loader provides for the movable pipe 7 to travel together within the stroke distance range.
[0035] An expansion member 18 is sleeved outside the movable pipe 7. A separator upper part 19 and a separator lower part 20 are respectively provided below the expansion member 18, and magnet groups 26 are respectively provided inside the separator upper part 19 and the separator lower part 20. A state sensor 21 is provided on one side of the separator upper part 19 and the separator lower part 20, and a state indicator light 22 is provided on one side of the state sensor 21. The cooperation of the separator upper part 19, the separator lower part 20, and the magnet group 26 plays a role in traction overload protection. When in a normal traction state, the magnet groups 26 inside the separator upper part 19 and the separator lower part 20 are closed. When the traction force on the lower or upper part of the movable pipe 7 is overloaded, the magnet groups 26 inside the separator upper part 19 and the separator lower part 20 are separated. The state sensor 21 is a switch for monitoring the closed or separated state, feeding back the signal to the system, and displaying it through the state indicator light 22.
[0036] In specific use, different magnet groups 26 can be selected to provide different separating forces.
[0037] The utility model can achieve high flow velocity, negative pressure self-sealing design, with less air leakage. It adopts a simple and effective traction overload protection design, can achieve intuitive state display and signal feedback. It can also use the active driving mode or the passive traction mode, with flexible use.
