Description

Technical Field

[0001] This utility model relates to the field of crushing equipment technology, specifically to an ore crushing equipment for mining. Background Technology

[0002] Ore refers to a mineral aggregate from which useful components can be extracted or which possesses certain usable properties. Ore can be used in engineering fields such as metal mining, metallurgy, chemical industry, construction, railway and highway construction, cement industry, and sand and gravel industry. After being mined, ore is generally large in volume, and crushing equipment is needed to break it down for easy transportation.

[0003] Currently, when crushing small ore blocks, it is difficult to uniformly feed small ore particles. Uneven feeding can cause certain parts inside the crusher to bear greater pressure, accelerate wear, and shorten the service life of the equipment. Moreover, during crushing, ore blocks can easily splash out from the inlet, accidentally injuring workers. Therefore, we have proposed an ore crushing equipment for mining to solve the above-mentioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an ore crushing equipment for mining, which solves the problem that when further crushing small ore blocks, it is difficult to uniformly feed small ore particles. Uneven feeding will cause certain parts inside the crusher to bear greater pressure, accelerate wear, shorten the service life of the equipment, and cause ore blocks to easily splash out from the inlet during crushing, accidentally injuring workers.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a mining ore crushing equipment, including a crushing box, wherein two sets of crushing toothed rods for crushing ore are rotatably connected inside the crushing box via bearings;

[0010] One end of one set of the crushing rods is fixed with a first sprocket, and one end of the rotating rod is fixed with a second sprocket by screws. A chain is meshed between the first sprocket and the second sprocket.

[0011] Preferably, when the rotating rod drives the multiple sets of fan plates to rotate, two sets of fan plates are always in contact with the inner sidewalls of the two sets of arc-shaped plates respectively, and the first sprocket and the second sprocket are both located outside the crushing box.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1 As shown:

[0026] A mining ore crushing device includes a crushing box 101.

[0027] In this implementation plan: To address the technical problems existing in the prior art, such as the "current crushing device, when further crushing some small ore blocks, has difficulty in uniformly feeding small ore particles, which leads to greater pressure on certain parts inside the crusher, accelerating wear, shortening the service life of the equipment, and causing ore blocks to splash out from the inlet during crushing, potentially injuring workers," this problem is clearly a real and difficult-to-solve issue. The electrical equipment involved in this product is powered by an external power source. The solution also includes an electrical control cabinet installed on the crushing box 101. During use, each piece of electrical equipment can be started individually through the control cabinet. The power connection methods of each piece of electrical equipment are existing mature technologies, well-known to those skilled in the art, and will not be elaborated upon here.

[0028] Furthermore:

[0029] like Figures 1-4 As shown:

[0030] Based on the above: Inside the crushing box 101, two sets of crushing toothed rods 102 for crushing ore are rotatably connected by bearings;

[0031] A drive mechanism 2 is installed on the crushing box 101 to drive the crushing rack 102 to rotate. The drive mechanism 2 includes a first gear 202 and a second gear 203 respectively fixed on two sets of crushing racks 102. The first gear 202 and the second gear 203 are meshed together. A drive motor 201 is fixedly installed on the surface of the crushing box 101 through a support plate. The output end of the drive motor 201 is fixedly connected to one of the sets of crushing racks 102.

[0032] A rotating rod 106 is rotatably connected to the top of the inner cavity of the crushing box 101 via a bearing;

[0033] Multiple sets of equidistantly arranged fan plates 107 are fixed to the surface of the rotating rod 106;

[0034] The inner wall of the crushing box 101 is fixed with symmetrically arranged arc-shaped pieces 108;

[0035] One end of a set of breaking toothed rods 102 is fixed with a first sprocket 103, and one end of a rotating rod 106 is fixed with a second sprocket 104 by screws. A chain 105 is meshed between the first sprocket 103 and the second sprocket 104.

[0036] When the rotating rod 106 drives the multiple sets of fan plates 107 to rotate, two sets of fan plates 107 are always in contact with the inner sidewalls of the two sets of arc-shaped plates 108 respectively. The first sprocket 103 and the second sprocket 104 are both located outside the crushing box 101.

[0037] In this implementation plan: When the ore crushing equipment for mining is in use, the ore is first put into the crushing box 101 and falls at the angle between the adjacent fan plates 107.

[0038] The drive motor 201 is connected to an external power source to supply power to the drive motor 201. The operation of the drive motor 201 drives the first gear 202 to rotate. The first gear 202 and the second gear 203 mesh and are connected, thereby driving the second gear 203 to rotate. Through the rotation of the second gear 203 and the first gear 202, the two sets of crushing toothed rods 102 can be driven to rotate relative to each other. The rotation of the two sets of crushing toothed rods 102 can crush the ore.

[0039] While one set of crushing toothed rods 102 rotates, it drives the first sprocket 103 to rotate. The first sprocket 103 and the second sprocket 104 are connected by a chain 105, which in turn drives the second sprocket 104 to rotate. The rotation of the second sprocket 104, in turn, drives the rotating rod 106 to rotate. As the rotating rod 106 rotates, it drives multiple sets of fan plates 107 to rotate, such as... Figure 4As shown: The cavity formed by the two sets of fan plates 107 and the arc-shaped plate 108 is the amount of ore to be fed. When it moves to the opening of the two sets of arc-shaped plates 108, the amount of ore stored at the included angle of the adjacent fan plates 107 is fed to the crushing tooth rod 102 through the opening, and the crushing tooth rod 102 is used to crush the ore.

[0040] Thus, through the cooperation of the fan plate 107, the rotating rod 106, and the arc-shaped plate 108, it is possible to ensure that small ore blocks are evenly distributed when entering the crusher, avoiding excessive pressure on the equipment due to excessive ore input, thereby reducing equipment wear. Moreover, when the rotating rod 106 drives multiple sets of fan plates 107 to rotate, two sets of fan plates 107 are always in contact with the inner walls of the two sets of arc-shaped plates 108, so that the top opening of the crushing box 101 is always in a blocked state, effectively controlling the splashing of ore blocks during the crushing process and protecting the safety of operators.

[0041] Furthermore;

[0042] In an optional embodiment, a strip plate 109 is fixedly installed at the included angle of adjacent fan plates 107. Multiple sets of equidistantly arranged heavy balls 112 are arranged between the strip plate 109 and the rotating rod 106. A top pin rod 110 is fixed to the surface of the heavy balls 112. A baffle plate 111 is fixed to the surface of the top pin rod 110. A shielding frame 113 is fixed to one side of the surface of the strip plate 109 to limit and block the multiple sets of baffle plates 111.

[0043] The surface of the strip plate 109 is provided with a circular hole that matches the top pin 110, and the top pin 110 and the strip plate 109 are slidably connected through this circular hole;

[0044] The heavy ball 112 is in a non-contact state with the adjacent fan plate 107.

[0045] In this embodiment: when the rotating rod 106 drives the fan plate 107 to rotate, when the adjacent fan plate 107 rotates to the lower position, the multiple sets of heavy balls 112 on one side of the strip plate 109 move downward due to gravity, causing the heavy balls 112 to drive the top pin rod 110 to move, so that the top pin rod 110 slides on the strip plate 109 and extends out from one side of the strip plate 109, thereby being able to push out the ore stuck at the angle of the adjacent fan plate 107, so that the ore can be released, thereby avoiding the ore from being stuck in the angle between the adjacent fan plates 107 for a long time, affecting the delivery of the ore;

[0046] A baffle 111 is fixed to the surface of the top pin 110, and a shield 113 is fixed to one side of the strip plate 109. The shield 113 can block the heavy ball 112, thereby preventing the baffle 111 from detaching from the strip plate 109. At the same time, the heavy ball 112 is not in contact with the adjacent fan plate 107, preventing the heavy ball 112 from being at the angle between the adjacent fan plates 107, thus improving the use effect of this structure.

[0047] The working principle and usage process of this utility model are as follows: When using this ore crushing equipment for mining, the ore is first placed into the crushing box 101 and falls at the angle between adjacent fan plates 107. The drive motor 201 is connected to an external power source to supply power. The operation of the drive motor 201 drives the first gear 202 to rotate. The first gear 202 meshes with the second gear 203, thereby driving the second gear 203 to rotate. Through the interaction between the second gear 203 and the first gear 202… The rotation of gear 202 drives two sets of crushing gears 102 to rotate relative to each other, thus crushing the ore. Simultaneously, the rotation of one set of crushing gears 102 drives the first sprocket 103 to rotate. The first sprocket 103 and the second sprocket 104 are connected by a chain 105, which in turn drives the second sprocket 104 to rotate. The rotation of the second sprocket 104 then drives the rotating rod 106 to rotate, which in turn drives multiple sets of fan plates 107 to rotate. Figure 4 As shown: The cavity formed by the two sets of fan plates 107 and the arc-shaped plates 108 is the ore feeding volume. When it moves to the opening of the two sets of arc-shaped plates 108, the amount of ore stored at the included angle of the adjacent fan plates 107 is fed onto the crushing tooth rod 102 through the opening, and the crushing tooth rod 102 crushes the ore. Thus, through the cooperation of the fan plates 107, the rotating rod 106 and the arc-shaped plates 108, it can be ensured that small ore blocks are evenly distributed when entering the crusher, avoiding excessive pressure on the equipment due to excessive ore feeding, thereby reducing equipment wear. Moreover, when the rotating rod 106 drives the multiple sets of fan plates 107 to rotate, two sets of fan plates 107 are always in contact with the inner sidewalls of the two sets of arc-shaped plates 108, so that the top opening of the crushing box 101 is always in a blocked state, effectively controlling the splashing of ore blocks during the crushing process and protecting the safety of the operators.
