Travel switches 27 are respectively arranged on the inner wall of the garbage storage chamber 1 near the upper limit position and the lower limit position of the scraping plate 6; the travel switch 27 is electrically connected to the controller 13. The travel switches 27 are of the type YBLX-19/111, and two travel switches 27 can control the rotation amount of the motor 26 and control the forward and reverse rotation of the motor 26. The travel switch is a proximity switch, and as long as the scraping plate 6 or the lifting plate 6 reaches the set induction range, the travel switch can send a signal to the controller. Whether the motor 26 is rotated and the rotation direction are controlled by the controller 13.

Furthermore, the contact end of the scraping plate 6 and the push plate 2 is in a conical structure, and the scraping performance is improved by the arrangement. The two ends of the positioning rod 23 are welded on the inner wall of the garbage storage chamber 1, the two ends of the lifting screw rod 22 are in interference fit with the bearing inner ring on the inner wall of the garbage storage chamber 1, the output shaft of the motor 26 is welded at the upper end of the lifting screw rod 22, the model of the motor 26 is a VARVEL brake locking type, the motor 26 is connected onto the outer wall of the garbage storage chamber 1 through a bolt, a wire of a power control end of the motor 26 is connected onto the controller 13, and a power end of the motor 26 is connected onto

And a position measuring mechanism for detecting whether the push plate 2 reaches a position corresponding to the scraper 6 in the front-back direction is arranged on the inner wall of the garbage storage chamber 1 or a fixing piece connected with the inner wall. The positioning mechanism may be various, such as a position sensor, a laser range finder, or the like, and may be any of those known in the art. The adoption of the position measuring mechanism can ensure that the relative position between the scraping plate 6 and the push plate 2 is more accurate and the cleaning efficiency is ensured.

The position measuring mechanism comprises a positioning ring groove 4 arranged on a fixing piece connected with the inner wall or the inner wall of the garbage storage chamber 1, a positioning cylinder 5 corresponding to the positioning ring groove 4 is arranged on one side wall of the push plate 2, and specifically, the positioning cylinder 5 is welded on the side wall in front of the push plate 2. When the location, push pedal 2 removes to a location section of thick bamboo 5 and inserts positioning ring groove 4, and a location section of thick bamboo 5 carries on spacingly when returning push pedal 2. Be equipped with through-hole 14 on the 4 diapalls of positioning ring groove, laser range finder 15 has been installed to through-hole 14 one side, 15 outputs of laser range finder are installed on controller 13, warning light 16 has been installed to controller 13 output, warning light 16 is installed store up on the garbage chamber 1 outer wall.

Specifically; the left side of the through hole 14 is connected with a laser range finder 15 through a bolt, the model of the laser range finder 15 is LS-P, and the laser range finder 15 measures the position between the laser range finder 15 and the positioning cylinder 5. The output end of the laser range finder 15 is connected with the controller 13 through a lead, the output end of the controller 13 is bonded with a warning lamp 16, the model of the warning lamp 16 is LED-505-T3J, and the warning lamp 16 is bonded on the outer wall of the garbage storage chamber 1. The laser distance measuring instrument 15 judges whether the push plate 2 is in place or not by measuring the distance between the laser distance measuring instrument and the positioning cylinder 5. If the measured distance is a set value, the controller 13 receives the signal and then obtains the warning light 16 to warn that the push plate 2 is at the initial set position, otherwise, the distance is not measured. When the push plate 2 is at the set position, the lifting mechanism drives the scraper 6 to lift and clear the garbage on the push plate 2.

Or, in another structure, the position measuring mechanism includes the connecting block 8, the connecting block 8 is provided with the moving contact 9, the inner wall of the top end of the garbage storage chamber 1 is symmetrically provided with the static contacts 10, the moving contact 9 corresponds to a position between the two static contacts 10, the static contact 10 is provided with the wire 11, the wire 11 is provided with the indicator light 12, the indicator light 12 is arranged on the outer wall of the garbage storage chamber 1, the output end of the indicator light 12 is provided with the controller 13, and the controller 13 is arranged on the outer wall of the garbage storage chamber 1.
