A moving base plate 701 is arranged below the discharging basket 6, a transmission screw rod 702 is arranged below the moving base plate 701, one end of the transmission screw rod 702 is provided with a second motor 703, L-shaped slide bars 704 are arranged on the left side and the right side of the discharging basket 6, a sensor 501 is arranged at the top of the left surface of the discharging basket 6, a receiver 502 is arranged on the inner side of the lifting upright post 4, rectangular grooves 602 are formed in the left side and the right side of the discharging basket 6, and the rectangular grooves 602 are in sliding fit with the L-shaped lifting; the during operation, drive screw 702 drives motion backing plate 701 and moves, drive screw 702 just reverses and can see motion backing plate 701 off and connect back, drive screw 702 carries and rectangle recess 602 cooperation L type lift 403 is used for the location to blowing basket 6 clamping position, guarantee that blowing basket 6 stop position is unchangeable at every turn, the left and right sides is equipped with L type slide bar 704, guarantee to be in same water flat line all the time about blowing basket 6, and can play fine support to blowing basket 6, blowing basket 6 below is equipped with transport mechanism can make blowing basket 6 back and forth movement, reduce the injury that personnel are close the spraying position and cause.

The moving base plate 701 is U-shaped, the moving base plate 701 is tightly matched with the discharging basket 6, and positioning stoppers 601 are arranged at the front and the rear of the discharging basket 6; during operation, because the motion backing plate 701 need cooperate charging basket 6 to carry out the motion in the front and back direction, the motion backing plate 701 is position around the restriction charging basket 6 that the U type can be better, and U type motion backing plate 701 can be used for driving charging basket 6 and move, realizes the more accurate location of charging basket 6.

The working principle is as follows: the worker places workpieces in the discharge basket 66 in batches, positioning stoppers 601 are arranged on the front side and the rear side of the discharge basket 66 for positioning the workpieces, the discharge basket 66 is conveyed to a clamping position through a transmission screw rod 702, the distance between the transmission screw rod 702 and a rectangular groove 602 limit the front position and the rear position of the discharge basket 6, when the discharge basket 6 is conveyed to a clamping position, a telescopic cylinder 202 starts to stretch and draw to drive a clamping device to move downwards to grab a piece, the left telescopic hook claw 302 and the right telescopic hook claw 302 hook a ratchet 406 to rotate when the clamping device moves downwards, a first rotating shaft 405 is arranged in the middle of the ratchet 406, the screw rod part of the first rotating shaft 405 is matched with the screw rod part of an L-shaped lifting piece 403 to drive the L-shaped lifting piece 403 to move upwards, the lower part of the L-shaped lifting piece 403 extends out to be matched with the rectangular groove 602 to drive the discharge basket 6 to move upwards to the grab position, and when the grab piece, therefore, the ratchet wheel 406 rotates every time the grabbing piece is carried out, and the position of the grabbing piece is always kept unchanged.

When the last piece of the discharge basket 6 is grabbed, the discharge basket 6 is lifted to the maximum position, the rear part of the ratchet 406 is provided with a positioning lifting device, the pawl 408 and the ratchet 406 are always in a hooked state, when the driving motor rotates, if the pawl 408 is not separated from the ratchet 406, the ratchet 406 or the pawl 408 is damaged, so that the positioning lifting device needs to be arranged behind the pawl 408, and when the driving motor 401 rotates, the positioning lifting device lifts the pawl 408 to ensure that the pawl is not matched with the ratchet 406, so that the purpose of lowering the discharge basket 6 is achieved. When the L-shaped lifting piece 403 rises, the stop 4032 will press the lifting slider 4026, but because the right side of the lifting slider 4026 is provided with the third spring, the lifting slider will return to the initial position, when the L-shaped lifting piece 403 rises for the last time, the L-shaped lifting piece 403 continues to move upwards to drive the pawl 408 to lift, so that the pawl 408 is disengaged from the ratchet 406, when the top plate 4037 falls, the top plate 4037 will be stopped by the upper part of the rotating block 4020 being a plane, so that the pawl 408 is always in a state of being disengaged from the ratchet 406, only when the L-shaped lifting piece 403 is driven by the driving motor to fall to the initial position, the lifting slider 4026 in the stop 4032 will rotate inwards by the connecting rod, so that the blocking of the top plate 4037 is abandoned, the top plate 4037 can fall back to the initial position, so that the ratchet 406 and the pawl 408 are engaged again to realize the positioning, and the mechanism realizes the engagement of the ratchet 406 and the pawl 408 for different time, the lifting movement of the charging basket 6 is realized, so that the automatic lifting grabbing piece is realized.
