At the same time, most of the hoppers use hydraulic rods to achieve dumping. When the temperature is low, the viscosity of the hydraulic oil inside the hydraulic rod increases, reducing its influence speed. Therefore, during use, it is easy to affect the dumping efficiency of the hopper.

[0026] For the embodiments, please refer to Figures 1-3 , the present invention provides a technical solution:

[0027] A hopper lifting structure includes a hopper 1 and a support frame 2 arranged outside the hopper 1. Connecting shafts 3 are fixedly installed on both the left and right sides of the hopper 1. A limiting ball 4 is arranged at the inclined end of the bottom of the hopper 1. A support plate 5 is installed at the bottom of the hopper 1. A rotating support 501 and a limiting hole 502 are respectively arranged on the top of the support plate 5. A rotating motor 503 is fixedly installed on the left side surface of the rotating support 501 at the left end. A lifting mechanism 6 is arranged between the support plate 5 and the support frame 2;

[0028] Specifically, the rotating supports 501 are respectively located at the left and right ends of the hopper 1. The end of the connecting shaft 3 away from the hopper 1 is rotatably connected to the opposite side surface of the rotating support 501 through a bearing. The output end of the rotating motor 503 movably penetrates the left side surface of the rotating support 501 and is fixed to the left end of the connecting shaft 3. The inclined end of the bottom of the hopper 1 is arc-shaped. The limiting holes 502 are equidistantly distributed front and back on the top surface of the support plate 5 and are in corresponding fitting contact with the limiting balls 4;

[0029] In this implementation, the type of the rotating motor 503 is a reciprocating motor. The rotating motor 503 is mainly used to drive the connecting shaft 3 to rotate between the connecting shaft 3 and the rotating support 501, realizing the dumping of the hopper 1. Through the setting of the limiting balls 4, they are sequentially in fitting contact with the limiting holes 502, thereby achieving the function of quickly and stably dumping the hopper 1 and meeting the subsequent material dumping requirements.

[0030] It should be noted that the outer surface of the support plate 5 does not contact the inner wall of the support frame 2.

[0031] In this embodiment, please refer to Figure 1 、 Figure 2 and Figure 3 , the lifting mechanism 6 includes an upper fixed support 601, a lower fixed support 602 and a moving support block 603. The upper fixed supports 601 are respectively fixedly installed at the inner top end of the support frame 2. Adjusting motors 604 are respectively fixedly arranged on the top of the upper fixed supports 601 at the rear end. The lower fixed supports 602 are respectively fixedly installed at the inner bottom end of the support frame 2, and adjusting screws 605 and positioning slide rods 606 are respectively rotatably arranged between them and the upper fixed supports 601. The moving support blocks 603 are respectively fixedly installed at the left and right ends of the support plate 5;

[0032] Specifically, the output end of the adjusting motor 604 penetrates the top surface of the upper fixed support 601 and is fixed to the top end of the adjusting screw 605. The bottom end of the positioning slide rod 606 slidably penetrates the top surface of the moving support block 603 and extends downward. The bottom end of the adjusting screw 605 is threadedly penetrated through the top surface of the moving support block 603 and extends downward;

[0033] In this embodiment, the type of the adjusting motor 604 is a reciprocating motor. The setting of the adjusting motor 604 is mainly used to drive the adjusting screw 605. Under the screw thread fit between the adjusting screw 605 and the moving support block 603 and the sliding fit between the positioning slide bar 606 and the moving support block 603, the moving support block 603 drives the support plate 5 to move smoothly up and down along the outer surface of the positioning slide bar 606, meeting the lifting requirement of the hopper 1.

[0034] The working process of the present utility model: When using a hopper lifting structure, first move the device to the required position, and then place the material in the hopper 1. When it is necessary to lift the hopper 1, start the adjusting motor 604. The output end of the adjusting motor 604 drives the adjusting screw 605 to rotate. Then, a screw thread engagement movement occurs between the adjusting screw 605 and the moving support block 603 at the rear end. At this time, the moving support block 603 at the front side slides along the outer surface of the positioning slide bar 606, and the support plate 5 drives the hopper 1 to move with the movement of the moving support block 603 until the hopper 1 moves to a suitable position, facilitating the staff to lift the height of the hopper 1. Further, when it is necessary to tilt the hopper 1, start the rotating motor 503. The output end of the rotating motor 503 drives the connecting shaft 3 to rotate, and the connecting shaft 3 drives the hopper 1 to tilt. Then, the limiting ball 4 is successively in contact with the limiting hole 502, ensuring the smoothness of the tilting of the hopper 1 and facilitating the subsequent material dumping operation.

[0035] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
