The working process of the invention is as follows: when materials need to be shoveled and filled into a fixed container, the container needing to contain the materials is fixed at the lower end of the funnel 42 through a plurality of hooks arranged on the periphery of the lower end of the funnel 42, and a feed inlet of the container is opposite to a discharge outlet of the funnel 42; then the double-hand pushing vehicle body 1 moves forwards, the wheels 6 which move forwards and rotate drive a first gear 14 matched with the wheels through a key to rotate synchronously through the axle 5, the first gear 14 drives a second gear 15 meshed with the first gear to rotate, and the second gear 15 drives an outer ring of a one-way clutch 45 to rotate synchronously; at this time, the one-way clutch 45 does not produce a one-way driving effect, and the outer ring of the one-way clutch does not drive the inner ring of the one-way clutch to rotate; the inner ring of the one-way clutch 45 cannot drive the two wire winding wheels to rotate through the transmission shaft 16 in key fit with the one-way clutch, the steel wire rope 25 wound on the wire winding wheels does not move, and the bucket 35 does not move; under the limit pushing of the guide block 41 to the bucket 35, the head of the bucket 35 enters the material and shovels the material; the two handles 10 which act on the vehicle body 1 simultaneously by two hands pull the vehicle body 1 backwards; in the process of pulling the vehicle body 1 backwards, the vehicle handle 10 is pressed downwards by two hands, so that the friction force of the wheels 6 on the ground is increased under the action of the torque generated by the full-load bucket 35 and the two hands on the vehicle body 1, and the wheels 6 are prevented from slipping; the wheel 6 rotating in the opposite direction drives the first gear 14 to rotate in the opposite direction through the axle 5; the first gear 14 drives the second gear 15 engaged with the first gear to rotate; at this time, the one-way clutch 45 plays a one-way driving role, the second gear 15 drives the outer ring of the one-way clutch 45 to rotate, the outer ring of the one-way clutch 45 drives the transmission shaft 16 to rotate through the inner ring of the one-way clutch 45, and the transmission shaft 16 drives the two winding wheels to synchronously rotate; the two winding wheels start to wind the steel wire rope 25; the two steel wire ropes 25 pull the two fixed blocks 27 to move upwards along the guide groove 9 at the same time, and the two second sliding blocks 28 fixedly connected with the two fixed blocks 27 respectively drive the bucket 35 to move upwards along the guide groove 9 through the swing shafts 29; meanwhile, the guide block 41 mounted on the upper end surface of the board 4 acts on the tail of the bucket 35, so that the bucket 35 swings to a certain extent around the central axis of the swing shaft 29 toward the tail of the vehicle body 1 in the process of rising along the guide groove 9; the materials in the bucket 35 move to the tail of the bucket 35 again, so that the leakage of the materials from the front opening of the bucket 35 in the lifting process of the bucket 35 is avoided; the vehicle body 1 continues to move backwards, the bucket 35 continues to move towards the top of the guide rail 8 along the guide groove 9 and passes over the guide block 41, and the two second clamping blocks 39 arranged on the baffle 37 at the tail part of the bucket 35 meet and interact with the unlocking rods 12 arranged on the two side supporting plates 2 respectively; due to the interaction of the limiting block 30 arranged on the swing shaft 29 and the first clamping block 34 arranged in the sliding groove of the hinge block 31, the bucket 35 cannot swing around the central axis of the swing shaft 29 any more, and at the moment, the bucket 35 reaches the maximum inclination angle; when the bucket 35 moves upwards along the guide groove 9 and starts to reach the upper part of the hopper 42, under the action of the two unlocking levers 12, the two second clamping blocks 39 simultaneously drive the baffle 37 fixedly connected with the two second clamping blocks to slide obliquely downwards, the tail part of the bucket 35 is gradually opened, the two second return springs 40 positioned at the two sides of the bucket 35 are simultaneously stretched, and materials are poured out of the bucket 35 through the opened tail part of the bucket 35 and fall into the hopper 42 below; when the wheels 6 of the vehicle body 1 rotate reversely for one circle, the bucket 35 reaches the top of the guide rail 8 along the guide groove 9, the two unlocking rods 12 drive the baffle 37 to move downwards in an inclined mode to the limit position through the two second clamping blocks 39, the opening at the tail of the bucket 35 is the largest, most of materials in the bucket 35 fall into the funnel 42, the materials slide into the material container below through the funnel 42, and the material container is filled.

When the materials in the bucket 35 are completely poured, the container filled with the materials is taken down from the vehicle body 1, and the empty material container is replaced again; then the vehicle body 1 is pushed forwards, and the wheels 6 rotating in the reverse direction drive the first gear 14 to rotate through the axle 5; the first gear 14 drives the second gear 15 to rotate reversely; the second gear 15 drives the outer ring of the one-way clutch 45 to rotate reversely, at this time, the one-way clutch 45 does not produce a one-way driving effect, and the outer ring does not drive the inner ring to rotate; under the action of the gravity of the bucket 35, the bucket 35 moves towards the bottom of the guide rail 8 along the guide groove 9; the bucket 35 drives the wire winding wheel to rotate reversely through the steel wire rope 25 and delivers the steel wire rope 25; the two winding wheels drive the inner ring of the one-way clutch 45 to rotate through the transmission shaft 16, and the rotation direction of the two winding wheels is the same as that of the outer ring; if the speed of pushing the vehicle body 1 forward is high, the outer ring rotating speed of the one-way clutch 45 is greater than the inner ring rotating speed thereof, at the moment, the one-way clutch 45 does not generate a one-way driving effect, the inner ring thereof rotates without obstacle under the action of the gravity of the bucket 35, and the bucket 35 falls back quickly under the action of the gravity of the bucket 35; if the speed of pushing the car body 1 forwards is slow, the rotating speed of the outer ring of the one-way clutch 45 is far less than that of the inner ring of the one-way clutch 45 due to the gravity action of the bucket 35, at the moment, the one-way clutch 45 plays a one-way driving role, the slow movement of the car body 1 enables the outer ring of the one-way clutch 45 to rotate slowly, and further the rotating speed of the inner ring of the one-way clutch 45 is limited, so that the falling speed of the bucket 35 is limited by the inner ring of the one-way clutch 45 through the wire winding wheel and the steel wire rope 25, the impact of the bucket 35 and the car plate 4 caused by the too fast falling speed of the bucket 35; during the downward movement of the bucket 35 along the guide groove 9, the two lock release levers 12 mounted on the two side brackets 2 gradually release the restriction of the stopper 37; under the combined action of the two second return springs 40, the baffle 37 moves along the corresponding chute to the initial position on the bucket 35 and gradually closes the rear opening of the bucket 35; when the two second latches 39 mounted on the shutter 37 are disengaged from the release lever 12, the opening at the rear of the bucket 35 is completely closed by the shutter 37; bucket 35 continues to move down channel 9, and when the tail of bucket 35 meets guide block 41, guide block 41 acts on the tail of bucket 35 to swing bucket 35 about the central axis of swing shaft 29 toward the horizontal position, and when bucket 35 swings to the horizontal position, bucket 35 just reaches deck 4; when the bucket 35 reaches the vehicle plate 4, the vehicle body 1 is pushed by two hands again to continue moving to the material pile and enable the bucket 35 to shovel the materials, the vehicle body 1 is pulled backwards again to enable the bucket 35 to move towards the top of the guide rail 8 and pour the materials into the funnel 42, the materials enter the container below the funnel 42 again and fill the container, and the operation is repeated, so that the materials are loaded into the material container and are transferred.

When the unloaded vehicle body 1 needs to move to a certain position in the backward direction, the vehicle body 1 does not need to be pushed to turn around, at the moment, only one hand is needed to push the push rod 22 to move forward relative to the vehicle body 1 along the guide groove on the guide block 13, the push rod 22 drives the first slide block 21 fixedly connected with the push rod 22 to move forward along the transmission cavity 18 towards the vehicle body 1, and the first return spring 23 embedded on the push rod 22 is further stretched; the first sliding block 21 drives the transmission shaft 16 matched with the bearing of the first sliding block to move towards the front of the vehicle body 1 along the two second shaft grooves 20 on the inner sides of the two side supporting plates 2, the transmission shaft 16 drives the second gear 15 matched with the transmission shaft 16 and the two wire winding wheels to move towards the front of the vehicle body 1 together, the second gear 15 is separated from the first gear 14, the first gear 14 and the second gear 15 do not have a transmission relation at the moment, the situation that the first gear 14 drives the transmission shaft 16 to rotate through the second gear 15 and the one-way clutch 45 playing a one-way driving role at the moment when the vehicle body 1 retreats is avoided, the two wire winding wheels arranged at two ends of the transmission shaft 16 do not rotate, the steel wire rope 25 with one end wound on the wire winding wheels does not move, transmission does not occur in the whole charging device, and.

In conclusion, the invention has the beneficial effects that: the charging device is low in manufacturing cost and small and convenient to use; the automatic charging can be realized only by one person during the operation, so that the labor cost is greatly saved; and this device does not form the noise in the use, and easy operation, does not constitute the influence to resident's life on every side, really realizes green construction.
