[0019] Compared with the prior art, the beneficial effects of the present utility model are: The feed hopper for a mining machine with a quantitative feeding mechanism

[0020] (1) In this case, by setting a connecting plate, a material receiving plate, and a rotating motor in the feeding hopper structure, the problem in the above-mentioned case that the feeding hopper does not have quantitative feeding of materials is solved. As a result, all the materials entering the inside of the feeding hopper are poured down. When all the materials are poured down, it is easy to shorten the service life of the material receiving equipment. When the materials need to be fed, at this time, the operator controls the rotating motor to drive the connecting plate to rotate under force. When the connecting plate rotates under force, it drives the material receiving plate to rotate synchronously under force. The quantitative feeding of materials is controlled by the length of the material receiving plate and the installation distance between the material receiving plates.

[0021] (2) By setting a reciprocating cylinder, a toothed plate, a through-hole concave block, a buffer plate, and a mounting spring in the feeding hopper structure, the problem that the inner wall of the feeding hopper body is easily damaged by the collision of materials during the falling process and the feeding hopper body is blocked due to the large falling materials is solved. When the materials fall into the inside of the feeding hopper body, at this time, the materials come into contact with the buffer plate. When the buffer plate contacts the materials, the falling speed of the materials is reduced. And when the materials fall between the toothed plates, the reciprocating cylinder controls the toothed plate to move under force to crush the large materials.

[0022] (3) By setting an anti-blocking structure, it is avoided that the inside of the feeding hopper body is easily blocked when the materials fall. When the control motor is working, the eccentric disk drives the concave block and the through-frame to move under force. When the through-frame moves under force, it drives the connecting shaft to move reciprocally under force. During the process of the connecting shaft moving reciprocally under force, the driving rod and the knocking hammer agitate the materials reciprocally for feeding and knock on the inner wall of the feeding hopper body for vibrating feeding.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1-5 , the present invention provides a technical solution: a feeding hopper for a mining machine with a quantitative feeding mechanism, as Figure 1 and Figure 2 shown, which includes a feeding hopper structure 1. The feeding hopper structure 1 includes a feeding hopper body 101 with a hollow structure inside, and the feeding hopper body 101 is provided with fixing holes for convenient installation of components. At the same time, a connecting plate 102 is rotatably installed inside the feeding hopper body 101.

[0031] Further, a material receiving plate 103 is welded and fixed on the surface of the connecting plate 102, and the connecting plate 102 is rotationally adjusted by a rotating motor 104 at the rear side of the feeding hopper body 101. Among them, 8 material receiving plates 103 are provided. By using the 8 material receiving plates 103 to be fixedly connected to the connecting plate 102 at equal intervals, the material receiving plates 103 can quantitatively rotate and receive materials between them.

[0032] Further, a reciprocating cylinder 105 is fixed to the feeding hopper body 101 through a fixing hole, and a tooth plate 106 is fixed to the output end of the reciprocating cylinder 105. At the same time, a through-hole concave block 107 is fixed above the inside of the feeding hopper body 101. Among them, 1 set of the above components is provided. When 1 set of the above components is provided, it can effectively relatively extrude the falling materials. By relatively extruding the materials, large materials can be extruded and broken for convenient feeding.

[0033] Further, in the above solution, a buffer plate 108 is rotatably installed on the through-hole bump 107 through a connecting pin, and a mounting spring 109 is fixed inside the buffer plate 108 and the feed hopper body 101. Among them, the above components form a rotational elastic adjustment structure, and when using the rotational elastic adjustment structure composed of the above components, it effectively buffers the falling material.

[0034] In the above solution, when the material enters the inside of the feed hopper body 101, it contacts the buffer plate 108 to reduce the falling speed of the material, and then falls between the toothed plates 106. When pushed by the reciprocating cylinder 105, the material is squeezed and crushed. The crushed material falls between the receiving plates 103, and the rotational motor 104 is used for quantitative rotational feeding. Moreover, the rotation speed of the rotational motor 104 is controlled and adjusted to prevent the rotational motor 104 from rotating too much and causing inability to quantitatively receive and feed the material.

[0035] As Figure 3 、 Figure 4 and Figure 5 shown, an anti-blocking structure 2 is provided inside the feed hopper structure 1. The anti-blocking structure 2 includes a connecting shaft 201 with a knocking hammer 202 fixed at one end, and a driving rod 203 is welded and fixed on the surface of the connecting shaft 201. At the same time, the connecting shaft 201 passes through the fixing hole and is welded and fixed to the through-frame 204.

[0036] Further, in the above solution, the connecting shaft 201 slides and adjusts through a guide wheel 205 and a through-hole plate 206, and the through-hole plate 206 is fixed inside the feed hopper body 101 through a fixing nut. At the same time, an eccentric disc 207 with rotational adjustment is provided in the through-hole plate 206 through a control motor 208.

[0037] Further, in the above solution, the eccentric disc 207 is rotatably connected to a bump 209 through another connecting shaft 201, and the bump 209 is slidably and matingly connected to the through-frame 204.

[0038] In the above solution, during the operation of the control motor 208, the eccentric disc 207 drives the bump 209 and the through-frame 204 to move under force. When the through-frame 204 moves under force, it drives the connecting shaft 201 to move reciprocally under force. During the process of the connecting shaft 201 moving reciprocally under force, the driving rod 203 and the knocking hammer 202 agitate the material reciprocally for feeding and knock the inner wall of the feed hopper body 101 for vibrating feeding.

[0039] The orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of simplifying the description of the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation on the protection scope of the present invention.
