As the main production material of mines, ore is characterized by large quantity and high dust content, and occupational hazards are relatively serious. Especially at material transfer points, such as ore hoppers, which are key points for ore transportation and are often operating at full capacity. The traditional practice is that operators use construction machinery such as excavators, forklifts, and dump trucks to push materials. However, this method will generate a lot of dust during the pushing process, exacerbating the problem of occupational hazards. In addition, there is a safety risk that engineering vehicles may accidentally fall into the hopper during the pushing process, which increases the danger of the operation. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solution of the utility model is described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments.

[0020] like Figure 1 and 2A ore hopper pushing device comprises a pushing plate and a base fixedly mounted on the ground, on which two groups of left and right first oil cylinders 1 and second oil cylinders 3 are symmetrically mounted, and a group of connecting rod mechanisms are respectively mounted on the upper end of each group of first oil cylinders 1 and second oil cylinders 3, and the two groups of connecting rod mechanisms are symmetrically arranged; each group of the connecting rod mechanisms comprises a plurality of rotatably connected connecting rods and a motor for driving one of the connecting rods to rotate.

[0021] The two ends of the push plate are respectively connected to the ends of the two groups of connecting rod mechanisms; the push plate includes three concave arc panels, and the long sides of the three concave arc panels are connected end to end to form a triangular push plate 10. A groove is provided at the top corner of the triangular push plate 10, and a wear-resistant tube 11 is installed in the groove.

[0022] The connecting rod mechanism includes a first connecting rod 5, a second connecting rod 6, a third connecting rod 7, and a fourth connecting rod 8; a first articulated base 2 is fixed to the upper end of the first oil cylinder 1, and a second articulated base 4 is fixed to the upper end of the second oil cylinder 3; the front end of the first connecting rod 5 is connected to the rear end of the second connecting rod 6, and the rear end of the first connecting rod 5 is rotatably connected to the first articulated base 2, and the motor is installed on the first articulated base 2 to drive the first connecting rod 5 to rotate; the middle part of the second connecting rod 6 is rotatably connected to the front end of the third connecting rod 7, and the rear end of the third connecting rod 7 is rotatably connected to the first articulated base 2. The second hinged base 4 is rotatably connected; the front end of the second connecting rod 6 is rotatably connected to the rear end of the fourth connecting rod 8, and the front end of the fourth connecting rod 8 is rotatably connected to the triangular push plate 10; the front part of the second connecting rod 6 is curved; a spring 9 is connected between the front part of the second connecting rod 6 and the fourth connecting rod 8; assuming that the length of the first connecting rod 5 is L1, the distance between the two hinge points of the front end of the first connecting rod 5 and the front end of the third connecting rod 7 on the second connecting rod 6 is L2, and the length of the third connecting rod 7 is L3, then the length ratio L1:L2:L3 is 30:50:38.

[0023] When in use, according to the height of the ore near the hopper, the height of the first oil cylinder 1 and the second oil cylinder 3 are adjusted so that the triangular push plate 10 is slightly higher than the top surface of the ore, and the motor drives the first connecting rod 5 to rotate around the first hinged base 2 through the reducer, driving the second connecting rod 6 to move forward, and the fourth connecting rod 8 drives the triangular push plate 10 to move, thereby pushing the ore near the ore hopper into the ore hopper. When the ore is not in the running track of the triangular push plate 10, the height of the first oil cylinder 1 and the second oil cylinder 3 is lowered so that the running track of the triangular push plate 10 can cover the ore, thereby pushing the ore near the ore hopper into the ore hopper in layers.

[0024] The height and angle of the ore hopper pushing device of the utility model can be adjusted to meet the pushing requirements of different ore quantities. When a large amount of ore needs to be pushed into the ore hopper in a short time, the first oil cylinder 1 can be appropriately extended (if necessary, the second oil cylinder 3 can also be appropriately extended synchronously), so that the bent part of the second connecting rod 6 is pressed down, and the triangular push plate 10 is obliquely inserted into the ore, so that the ore can be quickly pushed into the ore hopper.

[0025] When the amount of ore is too much, the resistance of the triangular push plate 10 increases, exceeding the load capacity of the device, and the ore advances slowly, under the action of resistance, the fourth connecting rod 8 rotates counterclockwise around the second connecting rod 6, the spring 9 is compressed, and the fourth connecting rod 8 is lifted up to drive the triangular push plate 10 to rise, thereby reducing the weight of the push material and ensuring the normal operation of the system. After the resistance is reduced, the fourth connecting rod 8 automatically returns to the initial position under the action of the spring 9.

[0026] It should be noted that it is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. The scope of the present invention is defined by the claims rather than the above description.
