DETAILED DESCRIPTION

[0022] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] Reference Figure 1 , Figure 2 and Figure 3 , an automatic locking structure for a dust box of an industrial and commercial sweeper, comprising a dust box 1, a hanging ear 2, a hook 3, a push rod driving device 4, a release switch 5 and an induction switch 6;

[0024] The present invention provides an automatic locking structure for the dust box of an industrial and commercial sweeper, which is installed on a frame 7. Specifically, the dust box 1 is movably installed on the frame 7, the hanging ears 2 are arranged on the left and right side vertical plates of the dust box 1, and the hooks 3 are arranged inside the left and right sides of the frame 7. When the dust box 1 is installed on the industrial and commercial sweeper, the position of the hook 3 is completely consistent with the position of the hanging ears 2 and the two are locked and connected together. The release switch 5 is installed at the edge of the frame 7 of the industrial and commercial sweeper, and the release switch 5 is used to pop the dust box 1 out of the frame 7 of the industrial and commercial sweeper. The induction switch 6 is arranged at the position where the dust box 1 is installed on the left or right inner wall of the frame 7 of the industrial and commercial sweeper (in this embodiment, it is located on the right inner wall), and the induction switch 6 is used to install the dust box 1 on the industrial and commercial sweeper. The push rod driving device 4 is located below the hook 3, and the release switch 5 and the induction switch 6 control the push rod driving device 4 to eject the dust box 1 or load it into the frame 7 of the industrial and commercial sweeper;

[0025] The dust collecting box 1 comprises a pull rod 11 and a box body 12;

[0026] The hanging ear 2 includes a left hanging ear 21 and a right hanging ear 22;

[0027] The hook 3 includes a left hook 31 and a right hook 32;

[0028] The left hook 31 includes a left groove 311;

[0029] The right hook 32 includes a right groove 321;

[0030] The push rod driving device 4 includes a left driving device 41 and a right driving device 42;

[0031] The induction switch 6 is a proximity switch sensor, which is square in shape and made of metal. The induction switch 6 is used to detect whether the dust box 1 is located inside the frame 7 of the industrial and commercial sweeper.

[0032] The left hook 31 and the right hook 32 are symmetrically arranged.

[0033] The hooks 3 are all "L"-shaped or quasi-"L"-shaped structures, with a groove in the middle that matches the hanging ear 2; when the hook 3 is lifted upward, the groove part can be tightly connected with the hanging ear 2.

[0034] The left hook 31 has a left groove 311 in the middle; the right hook 32 has a right groove 321 in the middle.

[0035] The hanging ear 2 is a circular or quasi-circular structure, the left hanging ear 21 and the right hanging ear 22 are symmetrically arranged, fixedly installed on the outer sides of the vertical plates on both sides of the dust box 1, and matched and connected with the left groove 311 and the right groove 321 on the left hook 31 and the right hook 32.

[0036] The left push rod driving device 41 and the right push rod driving device 42 respectively drive the left hook 31 and the right hook 32 to rise and fall; the push rod driving device 4 is fixedly connected to the hanging ear 2 through a nut.

[0037] The push rod driving device 4 can be a push rod motor or other driving devices such as a hydraulic cylinder, which provides driving force for the hanging ear 2 to rise or fall.

[0038] The pull rod 11 is arranged above the box body 12, so that the operator can pull out or push in the dust box. The box body 12 is a rectangular parallelepiped structure with a hollow interior for loading garbage.

[0039] The release switch 5 and the induction switch 6 are electrically connected to the push rod driving device 4 , and a microcomputer control system receives signals from the release switch 5 and the induction switch 6 and controls the lifting and lowering action of the push rod driving device 4 according to a preset logic.

[0040] Reference Figure 1 , Figure 2 and Figure 4When the dust box 1 is released by the automatic locking structure of the dust box of an industrial and commercial sweeper described in the present invention, the operator first needs to press the release switch 5 located on the control panel on the rear side of the sweeper to trigger the microcomputer control system to send a clear release instruction to the push rod drive device 4. After receiving the release instruction, the push rod drive device 4 will start its driving mechanism, and the electric motor or hydraulic cylinder will provide a power source to prompt the push rod drive device 4 to retract downward, and pull the hook 3 at the top of the push rod drive device 4 to smoothly descend along a preset path. As the hook 3 gradually descends, the ear 2 that was originally tightly hung in the left groove 311 and the right groove 321 begins to gradually separate from the hook 3. When the hook 3 is completely dropped to the preset position, the ear 2 is completely separated from the hook 3, so that the dust box 1 is smoothly ejected from the frame 7. At this time, the dust box 1 is successfully released, and the operator can pull out the dust box 1 by applying force to the pull rod 11 to dump the garbage inside the dust box 1.

[0041] Reference Figure 1 , Figure 2 and Figure 5 When the dust box 1 is locked by the automatic locking structure of the dust box of an industrial and commercial sweeper described in the present invention, the operator pushes the emptied dust box 1 back into the frame 7 of the sweeper through the pull rod 11 after completing the garbage dumping task. At this time, the sensor switch 6 preset in the frame 7 is triggered, and the sensor switch 6 detects the return state of the dust box 1, and then sends a signal to the microcomputer control system. After confirming that the dust box 1 has been correctly returned to the frame 7, the microcomputer control system sends a clear locking instruction to the push rod drive device 4 according to the preset program logic, and the push rod drive device 4 immediately starts its drive The mechanism is powered by an electric motor or a hydraulic cylinder to cause the push rod drive device 4 to extend upward, and push the hook 3 at the top of the push rod drive device 4 to rise smoothly along a preset path. As the left hook 31 and the right hook 32 gradually rise, the left groove 311 and the right groove 321 gradually contact the left hanging ear 21 and the right hanging ear 22 on both sides of the dust box 1. When the hook 3 rises to the preset position, the hook 3 and the hanging ear 2 are tightly connected. At this time, the dust box 1 is firmly locked in the preset working position in the frame 7. At this point, the dust box 1 is locked on the frame, which provides a reliable guarantee for the continued operation of the sweeper.

[0042] As described above, an automatic locking structure for the dust box of an industrial and commercial sweeper of the present invention controls the push rod driving device through the release switch and the induction switch to push the hook to rise and fall smoothly along a preset path, thereby achieving a tight connection or separation between the hook on the frame and the ear on the dust box, thereby completing the release and locking of the dust box of the industrial and commercial sweeper, solving the problems of inconvenience, laborious operation and potential danger in the release and reinstallation process of the dust box of the traditional sweeper in the background technology, which relies purely on manpower.
