[0002] As one of the key equipment in the ore dressing process, the crusher has the function of crushing ores with different sizes into materials with uniform particle sizes. Through its crushing treatment, the circulating load in the ore dressing process can be effectively reduced, thereby enhancing the processing capacity of the ore dressing plant and improving production efficiency.

[0003] After retrieval, in the related field, there is an authorized patent with the publication number of "CN221413251U" and the patent name of a crusher for ore dressing. Its structure specifically includes a machine body, a control panel is fixed on the side wall of the machine body, a feeding cover is fixed on the top of the machine body, a discharge hole is opened on the side wall of the machine body, a motor is fixed on the left side of the machine body, a rotating rod is fixed at the output end of the motor, a driving crushing roller is fixed on the outer wall of the rotating rod, a driving gear is fixed at the end point of the rotating rod, a rotating rod is rotatably installed on the inner wall of the machine body, and a driving crushing roller is fixed on the outer wall of the rotating rod.

[0004] Although the above-mentioned prior art ore crusher can play a role in crushing, it cannot pre-screen the ores that meet the specifications before crushing. When the ore raw materials are directly crushed without preliminary screening, the fine ores and the large ores will be processed by the crushing mechanism together. This situation will cause the crushing mechanism to need to process a material amount exceeding its reasonable load, thus extremely likely to increase the working load of the crushing mechanism. The excessive working load will cause the components inside the crushing mechanism to bear excessive pressure and friction, resulting in unnecessary wear. Therefore, another ore dressing crusher is provided specifically to solve the above technical problems. Summary of the Utility Model

[0005] The prior art ore crusher has the problem of excessive working load, which causes the components inside the crushing mechanism to bear excessive pressure and friction, resulting in unnecessary wear. The ore dressing crusher of the utility model uses a material cylinder with sieve holes and a spiral feeding rod to cooperate for feeding. During the process, the fine materials in the ores are pre-screened through the sieve holes and guided into the lower part of the inner cavity of the treatment box through a guide plate, avoiding contact with the main body of the crushing mechanism, and the larger ore materials are normally supplied to the crushing mechanism for crushing. In this way, without affecting the crushing efficiency and effect, the burden on the crushing mechanism is reduced, unnecessary wear is reduced, the service life of the main parts of the crushing mechanism is prolonged, and the above problems of the prior art ore crusher are successfully solved.

[0019] 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.

[0020] The front, rear, left, right, up and down in this embodiment are described with Figure 1 as the reference plane. Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0021] A beneficiation crusher includes a feeding box 1 and a processing box 2. Inside the processing box 2, there is a main crushing mechanism 3 and a sieve plate 4. It is characterized in that a primary screening fine material inlet 23 is penetrated and opened on the left side of the inner cavity of the processing box 2. A primary screening feeding device 5 is fixedly installed between the feeding box 1 and the processing box 2. The primary screening feeding device 5 includes a material cylinder 51. On the left side of the lower end of the material cylinder 51, a feeding pipe 511 is communicated. The feeding pipe 511 is embedded in the feeding box 1. On the left side of the upper end of the material cylinder 51, a discharging pipe 512 is communicated. The discharging pipe 512 is embedded in the processing box 2, and the discharging pipe 512 is located above the main crushing mechanism 3. A spiral feeding rod 52 is rotatably installed in the material cylinder 51. A driving motor 521 is fixedly installed on the lower surface of the material cylinder 51. The output end of the driving motor 521 is fixedly connected to the lower end of the spiral feeding rod 52. On the side of the material cylinder 51 close to the processing box 2, a plurality of sieve holes 513 are penetrated and opened. A guide plate 53 is fixedly installed between the side of the material cylinder 51 close to the processing box 2 and the processing box 2. The discharging end of the guide plate 53 is communicated with the primary screening fine material inlet 23;

[0022] It should be noted that a coarse material discharge port 22 is penetrated and opened on the front surface of the processing box 2. The position of the coarse material discharge port 22 corresponds to the position of the sieve plate 4. A fine material discharge port 21 is opened on the lower surface of the processing box 2;

[0023] During use, as shown in Figure 1 , the ore materials are put into the feeding box 1. Under the action of the slope plate in the feeding box 1, the materials are guided to the feeding pipe 511 of the material cylinder 51. After the ore materials enter the material cylinder 51, the driving motor 521 can be used to drive the spiral feeding rod 52 to rotate, thereby driving the ore materials to rotate and move upward. When the ore materials rotate to the position of the sieve holes 513, part of the fine ore materials will fall from the sieve holes 513, and pass through the guide plate 53 and enter the lower part of the inner cavity of the processing box 2 from the primary screening fine material inlet 23, avoiding being processed by the main crushing mechanism 3, thus reducing the load on the crushing mechanism, reducing unnecessary wear, and prolonging the service life of the parts of the main crushing mechanism. The larger ore materials will be carried to the discharging pipe 512, fall above the main crushing mechanism 3, and finally fall onto the sieve plate 4 after being crushed and screened. The coarse materials are discharged from the coarse material ticket buckle 22, and the fine materials are discharged from the fine material discharge port 21. Compared with the prior art, this beneficiation crusher can not only reduce the load on the main crushing mechanism 3, reduce unnecessary wear, and prolong the service life of the parts of the main crushing mechanism 3, but also the crushing process is carried out in a sealed manner inside the processing box 2, and the dust generated during crushing is not easily diffused to the outside, which can be more environmentally friendly.

[0024] Specifically, in combination with Figure 2 and Figure 3As shown, the material guiding plate 53 includes two side baffles 531 and a bottom supporting plate 532. The two side baffles 531 are symmetrically and fixedly installed between the left surface of the material cylinder 51 and the processing box 2, and the side baffle 531 is located outside the sieve holes 513. The bottom supporting plate 532 is fixedly installed between the left surface of the material cylinder 51 and the processing box 1, and the upper surface of the bottom supporting plate 532 is fixedly connected to the upper surfaces of the material cylinder 51 and the side baffle 531. Moreover, the gap between the upper surface of the bottom supporting plate 532 and the material cylinder 51 and the side baffle 531 is sealed by soldering. The fine materials screened out from the material cylinder 51 can be blocked by the side baffle 531 and the bottom supporting plate 532, and finally enter the processing box 1 through the primary screening fine material inlet 23 and are discharged from the fine material discharge port 21.

[0025] In addition, since the ore materials screened from the material cylinder 51 meet the fine material specifications and do not need to be screened by the sieve plate 4 anymore, in order to reduce the working intensity of the sieve plate 4, the primary screening fine material inlet 23 needs to be set below the sieve plate 4.

[0026] Finally, to improve the screening effect of the sieve plate 4, as Figure 4 shown, two support plates 24 are symmetrically and fixedly installed on the inner cavity side walls of the processing box 2. The front and rear of the sieve plate 4 are symmetrically and fixedly installed with directional sliding rods 41. The directional sliding rods 41 are slidably connected to the corresponding support plates 24. Moreover, springs 42 are fixedly installed between the upper surface of the support plate 24 and the lower surface of the sieve plate 4. A vibrating sieve motor 43 is fixedly installed at the center of the lower surface of the support plate 24. After the vibrating sieve motor 43 is powered on and started, the vibrating sieve motor 43 can drive the sieve plate 4 to move vertically up and down under the action of the springs 42 and the directional sliding rods 41, thereby improving the screening efficiency.
