Description

Technical Field

[0001] The utility model relates to the technical field of mining crushers, and particularly relates to a fast-breaking mining crusher. Background Art

[0002] Mining crushers are indispensable equipment in the process of mine exploitation. Their main function is to crush the mined ore to meet the requirements of subsequent processing or transportation.

[0003] However, there are some problems in the use of traditional mining crushers, especially in the aspects of ore feeding and crushing efficiency.

[0004] Existing mining crushers usually adopt a fixed feeding position, which causes the ore to mainly concentrate at a certain place in the crusher during crushing. This feeding method not only limits the distribution range of the ore inside the crusher, but also makes other positions of the crusher not fully utilized, resulting in a reduction in the working efficiency of the crusher, an increase in the crushing time and energy consumption. In addition, the fixed feeding position may also cause uneven stress on the ore during the crushing process, further affecting the crushing effect. The uneven stress may cause incomplete crushing of the ore, generating more fragments or large pieces of materials, which not only affects the quality of subsequent processing, but also may cause unstable factors to the operation of the crusher. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a fast-breaking mining crusher to solve the problems put forward in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A fast-breaking mining crusher includes a crusher. A screw conveyor is arranged on the left side of the crusher. The discharge port of the screw conveyor is located above the crusher. A movable feeding structure is arranged on the top of the crusher. The movable feeding structure is connected to the discharge port of the screw conveyor.

[0007] The movable feeding structure includes two support seats, a lead screw, a motor, a linear guide rod, two movable blocks, a discharge box and a discharge pipe. The two support seats are respectively arranged on the left and right sides of the top of the crusher. The lead screw is rotatably connected to the two support seats respectively. The motor is arranged on the support seat, and the driving end of the motor is connected to one end of the lead screw. The linear guide rod is arranged between the two support seats and is located behind the lead screw. The two movable blocks are respectively movably connected to the lead screw and the linear guide rod. The discharge box is arranged between the two movable blocks. A discharge pipe is arranged between the top of the discharge box and the discharge port of the screw conveyor.

[0008] Preferably, the lead screw is connected to the support seat through a bearing. The inner ring of the bearing is in interference fit with the lead screw, and the outer ring of the bearing is fixedly connected to the support seat.

[0009] Preferably, the discharge pipe is a telescopic corrugated hose.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows: The present utility model uses a screw conveyor for feeding. The screw conveyor has a continuous and uniform conveying capacity, which can effectively prevent the ore from being blocked or piled up during the conveying process, thus ensuring that the crusher can continuously and stably receive the ore for crushing. And the present utility model is provided with a mobile feeding structure on the crusher. This structure is connected to the discharge port of the screw conveyor. The design of the mobile feeding structure enables the ore to be evenly and comprehensively conveyed to every part of the crusher, avoiding the centralized feeding of the ore at a certain part of the crusher. The mobile feeding structure can make full use of each part of the crusher, thereby improving the crushing efficiency of the crusher. At the same time, since the ore can enter the crusher evenly and comprehensively, the force during the crushing process is more uniform, reducing unnecessary energy consumption and wear of machine parts. This can not only reduce production costs but also extend the service life of the crusher. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0016] Please refer to Figures 1-3, the present utility model provides a fast-breaking type mine crusher, including a crusher 1, the crusher 1 is an existing device, a screw conveyor 2 is arranged on the left side of the crusher 1, the screw conveyor 2 is an existing device, the discharge port of the screw conveyor 2 is located above the crusher 1, and a mobile feeding structure 3 is arranged on the top of the crusher 1, and the mobile feeding structure 3 is connected to the discharge port of the screw conveyor 2.

[0017] Specifically, the mobile feeding structure 3 includes two support seats 31, a lead screw 32, a motor 33, a linear guide rod 34, two movable blocks 35, a discharge box 36 and a discharge pipe 37. The two support seats 31 are respectively arranged on the left and right sides of the top of the crusher 1. The lead screw 32 is rotatably connected to the two support seats 31 respectively. The motor 33 is arranged on the support seat 31, and the driving end of the motor 33 is connected to one end of the lead screw 32. The linear guide rod 34 is arranged between the two support seats 31, and the linear guide rod 34 is located behind the lead screw 32. The two movable blocks 35 are respectively movably connected to the lead screw 32 and the linear guide rod 34. The discharge box 36 is arranged between the two movable blocks 35. The bottom of the discharge box 36 is an open structure. A discharge pipe 37 is arranged between the top of the discharge box 36 and the discharge port of the screw conveyor 2.

[0018] When the crusher 1 is working, the staff turns on the screw conveyor 2 and the mobile feeding structure 3. The screw conveyor 2 will transport the ore through the discharge pipe 37 into the discharge box 36, and then the discharge box 36 will guide the ore into the crusher 1 for crushing. During the feeding process, the motor 33 in the mobile feeding structure 3 will drive the lead screw 32 to rotate. Due to the limiting effect of the linear guide rod 34, the two movable blocks 35 can only drive the discharge box 36 to move horizontally in a straight line, so as to evenly and comprehensively transport the ore to every part of the crusher 1.

[0019] Specifically, the lead screw 32 is connected to the support seat 31 through a bearing. The inner ring of the bearing is in interference fit with the lead screw 32, and the outer ring of the bearing is fixedly connected to the support seat 31. This connection method not only ensures the smooth rotation of the lead screw 32, but also reduces friction and wear.

[0020] Specifically, the discharge pipe 37 is a telescopic corrugated hose. In order to adapt to the changes during the movement of the discharge box 36, the discharge pipe 37 adopts a telescopic corrugated hose design. This hose has good flexibility and durability, and can easily bend and stretch with the movement of the discharge box 36, ensuring that the ore can be smoothly transported from the screw conveyor 2 to the discharge box 36.

[0021] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand 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.
