[0026] See also Figures 1 to 3 , an automatic material pushing device, comprising: a frame 100 and a counterweight frame 200, the frame 100 is sequentially provided with a first ramp 110 and a second ramp 120 from top to bottom, the first ramp 110 and the second ramp 120 can make the material move downward obliquely under the action of gravity; the counterweight frame 200 is movably arranged on the frame 100, the counterweight frame 200 is connected to a first lifting frame 220 through a first rope body 210, the first lifting frame 220 is used to dock the material between the first ramp 110 and the second ramp 120, the counterweight frame 200 is connected to a limiting member 240 through a second rope body 230, the limiting member 240 is located on the first ramp 110 and is used to hinder the movement of the material, the first rope body 210 and the second rope body 230 are both wound with a fixed pulley 250; wherein, when the counterweight frame 200 descends, the limiting member 240 rises to release the limit on the material, and the first lifting frame 220 rises to dock the conveying end of the first ramp 110.
[0027] In the above-structured automatic material pushing device, the used empty box is located on the first ramp 110, the weight of the counterweight frame 200 is greater than the weight of the first lifting frame 220, and the limiter 240 can be engaged with the empty box located at the front of the conveying direction. When in use, the counterweight frame 200 moves down under the action of gravity, so that the first lifting frame 220 rises to the conveying end docking with the first ramp 110, and at the same time, the limiter 240 rises to release the limit of the empty box, so that the empty box slides down to the first lifting frame 220 under the action of gravity, and then people press down the first lifting frame 220, so that the first lifting frame 220 descends to the conveying starting end of the second ramp 120, which is conducive to people pushing the empty box to slide to the second ramp 120, and finally the counterweight frame 200 rises to make the limiter 240 descend, so that the limiter 240 again restricts the movement of the next empty box, which is conducive to the empty boxes changing layers one by one. Through the above steps, people can take the empty boxes with both hands and can move the empty boxes from the upper layer to the lower layer by standing. There is no need to bend over, which is helpful to reduce lumbar muscle strain and improve the convenience and efficiency of box changing.
[0028] See also Figure 1 and Figure 2 Further, the frame 100 includes two first rod groups arranged opposite to each other, each first rod group includes at least two vertical rods 101 arranged in parallel, and the first lifting frame 220 is provided with a receiving platform, and sliding wheels 221 are provided on both sides of the receiving platform, and the sliding wheels 221 are slidably matched with the vertical rods 101. Specifically, the sliding wheel 221 can be provided with a groove matched with the vertical rod 101, and the receiving platform moves up and down relative to the frame 100 through the pulley, thereby improving the smoothness of the movement of the first lifting frame 220. It can be understood that the counterweight frame 200 includes a connecting rod 202, and the two ends of the connecting rod 202 are respectively provided with moving wheels 201, and the frame 100 is provided with a vertical rod, and the moving wheels 201 are slidably matched with the vertical rod, so that the counterweight frame 200 moves up and down relative to the frame 100 through the moving wheels 201, which is conducive to improving the smoothness of the movement of the counterweight frame 200.
[0029] See also Figure 1 and Figure 2 Further, the receiving platform includes a plurality of parallel transverse rods 222, and a plurality of rollers 223 for contacting the materials are arranged between two adjacent transverse rods 222, so that rolling friction can be generated between the empty box and the rollers 223 by rolling, thereby reducing the resistance of the empty box to move, which is conducive to improving the smoothness of the empty box movement. It can be understood that the first ramp 110 and the second ramp 120 can also be provided with rollers 223, thereby reducing the resistance of the empty box to move, which is conducive to improving the overall smoothness of the empty box layer change.
[0030] See also Figure 1 and Figure 2Further, both ends of the transverse rod 222 are connected to lateral rods 224, and one end of the lateral rod 224 away from the first ramp 110 is connected to a pressure rod (not shown in the figure), which is rectangular and used for people to press down the receiving platform. It can be understood that the two lateral rods 224 extend in the vertical direction, and the two lateral rods 224 and the pressure rod together form a structure similar to a rectangular frame, so that people can push the receiving platform to dock with the conveying starting end of the second ramp 120 through the pressure rod, which is conducive to improving people's use experience.
[0031] See also Figure 1 and Figure 2 Furthermore, the receiving platform is provided with a first limiting rod 225, and the vertical rod 101 is provided with a second limiting rod 226 located below the first limiting rod 225, and the first limiting rod 225 abuts against the second limiting rod 226 to limit the movement of the receiving platform. It can be understood that when the first limiting rod 225 abuts against the second limiting rod 226, the receiving platform is slightly higher than the conveying start end of the second ramp 120, so that it is convenient for people to push the empty box to slide to the second ramp 120.

Specifically, when the counterweight frame 200 presses down the second lifting frame 260, the second lifting frame 260 moves downward to drive the limiter 240 to rise, thereby contacting the limiter 240 on the empty box, so that the empty box can slide onto the first lifting frame 220. When the counterweight frame 200 rises, since the weight of the second lifting frame 260 is less than the limiter 240, the limiter 240 moves downward under the action of gravity, and at the same time, the second lifting frame 260 rises, so that the limiter 240 again limits the movement of the next empty box.

[0034] See also Figure 1 and Figure 2 Furthermore, the frame 100 is provided with a second sleeve 103 , and the limiting member 240 is a rectangular frame, and the rectangular frame and the second sleeve 103 are slidably matched, which is beneficial to improve the smoothness of the sliding of the limiting member 240 relative to the frame 100 .
[0035] Furthermore, a blocking plate is provided at the conveying end of the second chute 120 to prevent the empty boxes from rushing out of the second chute 120 and scattering everywhere, which is conducive to people taking away the empty boxes in time.
