Description

Technical Field

[0001] This utility model belongs to the field of ore crushing and transportation technology, specifically an ore crushing conveyor. Background Technology

[0002] Ore crushing and conveying refers to the process of mechanically crushing mined ore using crushing equipment and then transporting the crushed ore using conveying equipment (such as belt conveyors and elevators). Originally mined ore has a large particle size and low efficiency when used directly. Through crushing and conveying, the particle size of the ore is reduced, which facilitates subsequent processes such as mineral processing and smelting, thereby improving resource utilization. In general, ore crushing and conveying is an indispensable process in modern industry. Its core function is to optimize ore particle size through physical means, improve resource utilization efficiency, reduce production costs, and ensure production safety.

[0003] Utility model patent application publication number 202321657616.7 discloses an ore crushing conveyor, belonging to the field of mining machinery technology. It includes: a base with four vertical plates symmetrically fixedly connected to its upper end; two adjacent sidewalls on the same side are rotatably connected to conveyor rollers, which are connected by a conveyor belt; and a crushing mechanism including a mounting frame, a cylinder, crushing plates, crushing teeth, and a baffle. The mounting frame is fixedly connected to the upper end of the base, and a cylinder is fixedly connected to the upper end of the mounting frame. The cylinder's output end passes through the top of the mounting frame and is fixedly connected to the crushing plate. When large pieces of ore are on the conveyor belt, the baffle intercepts them, and then the cylinder is activated, causing the crushing plate to strike the ore, thus crushing the large pieces into smaller pieces that can be conveyed downstream through the baffle. This mechanical structure is more time-saving, labor-saving, and efficient than manual crushing.

[0004] As can be seen from the above patent, there is an ore crushing conveyor, but it still has shortcomings in actual use. The most obvious one is that after the ore is crushed, it usually falls directly onto the conveyor belt of the conveyor. Due to the drop between the ore fragments and the conveyor belt, the surface of the conveyor belt will be subjected to impact and friction from the fragments, causing the rubber layer on the surface of the conveyor belt to wear quickly, shortening the service life of the conveyor belt, increasing the equipment maintenance cost and replacement frequency. Therefore, we propose an ore crushing conveyor. Utility Model Content

[0005] The purpose of this utility model is to provide an ore crushing conveyor to solve the problems mentioned in the background art.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] Specifically, this application describes an ore crushing conveyor, comprising: a conveying platform and a crushing box. Baffles are fixedly connected to both ends of the top of the conveying platform. The crushing box is fixedly connected between two sets of baffles. A rotating rod is fixedly connected between the two sets of baffles. A feeding plate is rotatably connected to the outer wall of the rotating rod. A guide groove is provided in the inner cavity of the feeding plate. A torsion spring is fixedly connected between the side wall of the feeding plate and the baffles. A roller is rotatably connected to one end of the feeding plate.

[0008] The upper end of the conveyor is rotatably equipped with a transmission belt, the crushing box is equipped with a crushing component for crushing ore, and the crushing box is equipped with a collection component for storing dust.

[0009] As a preferred technical solution of this application, the crushing component includes two sets of crushing rollers, which are rotatably disposed at both ends of the inner side wall of the crushing box. Two sets of gears are fixedly connected to one side wall of the crushing box, and the two sets of gears mesh with each other. The gears are fixed to the crushing rollers by a connecting rod.

[0010] As a preferred technical solution of this application, a first motor for driving a set of gears to rotate is fixedly connected to the side wall of the crushing box.

[0011] As a preferred technical solution of this application, the collection component includes a dust collection box, which is fixedly connected to one side wall of the crushing box. A dust collection fan is embedded in one side wall of the dust collection box. A through groove is opened in the inner cavity of the crushing box near the side wall of the dust collection box. A filter screen is slidably connected to the inner cavity of the through groove. A sliding component that applies a pushing force to the filter screen is provided in the through groove. A power component that facilitates the vibration of the filter screen is provided in the inner cavity of the crushing box.

[0012] As a preferred technical solution of this application, the sliding member includes a moving block and a spring. A sliding groove is provided at the bottom of the inner cavity of the through groove. The moving block is slidably connected to the inner cavity of the sliding groove. The spring is fixedly connected between the inner side wall of the sliding groove and the side wall of the moving block. The moving block is fixedly connected to the filter screen.

[0013] As a preferred technical solution of this application, the power component includes a rotating rod, which is rotatably disposed in the inner cavity of the crushing box near the filter screen. Protruding blocks are fixedly connected to both ends of the side wall of the rotating rod. The protruding blocks are used in conjunction with the filter screen. A protective frame for protecting the protruding blocks is fixedly connected to the inner cavity of the crushing box. A second motor for driving the rotating rod to rotate is fixedly connected to the side wall of the crushing box.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In the scheme of this application:

[0016] 1. By rotating a feeding plate at the bottom of the crushing box, and installing a torsion spring between the feeding plate and the baffle, the crushed pieces fall onto the feeding plate during feeding. Since the feeding plate has a guide groove, the crushed pieces move to one end of the feeding plate and drive the feeding plate to rotate around the rotating rod as the axis. At this time, one end of the feeding plate contacts the conveyor belt on the conveyor table through rollers, so that the crushed pieces are transported through the conveyor table. This reduces the degree of impact and friction of the crushed pieces on the conveyor belt, extends the service life of the conveyor belt, and reduces equipment maintenance costs and replacement frequency.

[0017] 2. By setting up a dust collection box and a dust extraction fan, dust generated by crushed ore fragments is collected. A second motor drives a rotating rod to rotate, which causes the convex block to repeatedly contact the filter screen. The filter screen moves repeatedly in the channel through the sliding parts, thereby removing impurities from the surface of the filter screen, reducing the occurrence of filter screen clogging and improving the crushing efficiency of ore.

A torsion spring 211 is fixedly connected between the side wall of the feed plate 220 and the baffle 110, and the torsion spring 211 applies an elastic force to the feed plate 220. A roller 221 is rotatably connected to one end of the feed plate 220. The roller 221 prevents the feed plate 220 from directly contacting the conveyor belt. A transmission belt is rotatably installed on the upper end of the conveyor table 100. The crushing box 200 is equipped with a crushing component for crushing ore and a collection component for storing dust.

[0028] Please see Figure 2 and Figure 3 The crushing component includes two sets of crushing rollers 230, which are rotatably mounted at both ends of the inner side wall of the crushing box 200. Two sets of gears 231 are fixedly connected to one side wall of the crushing box 200. The two sets of gears 231 mesh with each other and are fixed to the crushing rollers 230 by connecting rods. The first motor 232 drives one set of gears 231 to rotate, and the one set of gears 231 drives the other set of gears 231 to rotate in the opposite direction, thereby realizing the relative rotation of the two sets of crushing rollers 230 and crushing the ore through the crushing rollers 230.

[0029] Please see Figure 2 and Figure 3 The side wall of the crushing box 200 is fixedly connected to a first motor 232 for driving a set of gears 231 to rotate.

[0030] Please see Figure 1 , Figure 3 and Figure 4The collection component includes a dust collection box 240, which is fixedly connected to one side wall of the crushing box 200. A dust collection fan 241 is embedded in one side wall of the dust collection box 240. A through groove 250 is provided in the inner cavity of the crushing box 200 near the side wall of the dust collection box 240. A filter screen 260 is slidably connected to the inner cavity of the through groove 250. A sliding component is provided in the through groove 250 to apply a pushing force to the filter screen 260. A power component is provided in the inner cavity of the crushing box 200 to facilitate the vibration of the filter screen 260. Dust is drawn into the dust collection box 240 by the dust collection fan 241 and impurities such as stones are filtered through the filter screen 260.

[0031] Please see Figure 3-5 The sliding component includes a moving block 252 and a spring 253. A groove 251 is provided at the bottom of the inner cavity of the through groove 250. The moving block 252 is slidably connected to the inner cavity of the groove 251. The spring 253 is fixedly connected between the inner side wall of the groove 251 and the side wall of the moving block 252. The moving block 252 is fixedly connected to the filter screen 260. An elastic force is applied to the moving block 252 and the filter screen 260 by the spring 253.

[0032] Please see Figure 3-5 The power component includes a rotating rod 270, which is rotatably mounted in the inner cavity of the crushing box 200 near the filter screen 260. Protruding blocks 271 are fixedly connected to both ends of the side wall of the rotating rod 270, and these blocks cooperate with the filter screen 260. A protective frame 273 is fixedly connected to the inner cavity of the crushing box 200 to protect the protruding blocks 271. A second motor 272 is fixedly connected to the side wall of the crushing box 200 to drive the rotating rod 270 to rotate. An inclined plate is installed above the rotating rod 270 to protect it from falling ore. The second motor 272 drives the rotating rod 270 to rotate, causing the protruding blocks 271 to rotate. The protruding blocks 271 repeatedly contact the filter screen 260, causing the filter screen 260 to vibrate, thereby removing impurities adhering to the filter screen 260.

[0033] Specifically, in use, the ore crushing conveyor is first powered on, and the ore is added into the crushing box 200. Then, the first motor 232 drives a set of gears 231 to rotate, and one set of gears 231 drives another set of gears 231 to rotate in the opposite direction, thereby realizing the relative rotation of the two sets of crushing rollers 230. The crushing rollers 230 crush the ore, and the crushed stones fall onto the feed plate 220. At this time, the stones slide in the guide groove and drive the feed plate 220 to rotate around the rotating rod 21. The axis of 0 rotates, and then the feeding plate 220 drives the roller 221 to contact the conveyor belt, so that the stone feeding plate 220 falls onto the conveyor table 100. At the same time, the dust is collected by the dust collection fan 241 in conjunction with the dust collection box 240. At this time, the second motor 272 drives the rotating rod 270 to rotate, and the rotating rod 270 drives the convex block 271 to rotate. The convex block 271 repeatedly contacts the filter screen 260, causing the filter screen 260 to vibrate, thereby removing the impurities attached to the filter screen 260, thus completing the use.
