[0035] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0037] Please see Figure 1-4 As shown, this embodiment is a pretreatment device for low-grade copper ore recovery, comprising:

[0038] Main components: The main components include a fixed frame 11, a distribution box 12, a feed pipe 13, a ball mill 14, and a crusher 15;

[0039] The material distribution box 12 is fixedly connected to the upper front end of the fixed frame 11, the feeding pipe 13 is fixedly connected to the top of the material distribution box 12, the ball mill 14 is fixedly connected to the top of the fixed frame 11, and the crusher 15 is fixedly connected to the top of the ball mill 14.

[0040] The crusher 15 is used to provide space for crushing copper ore, the ball mill 14 is used to grind the crushed copper ore, the feeding bin 16 is used to provide space for feeding copper ore, and the distribution box 12 is used to screen the ground copper ore.

[0041] The pretreatment of low-grade copper ore mainly includes three steps: crushing, grinding and classification. Before entering the normal mineral processing process, copper ore needs to be pretreated to improve its processing efficiency and mineral processing effect.

[0042] The mined raw ore first undergoes crushing treatment in ball mill 14 to reduce the size of the ore and achieve the desired crushing effect. After crushing, the ore is screened in ball mill 14. Qualified materials enter the grinding stage, while unqualified materials are returned for further crushing. The particle size can be reduced to 0.15-0.2 mm. The grinding process can be a single-stage or two-stage grinding. The feed box 12 is mainly used to separate mineral particles according to their size, thereby improving processing efficiency.

[0043] All of the above parts are existing technologies;

[0044] Crushing assembly: The crushing assembly includes a housing 21, a motor 22, a mounting bracket 23, and a main bevel gear 24;

[0045] The housing 21 is fixedly connected to the top of the crusher 15, the mounting bracket 23 is fixedly connected to the inside of the housing 21, the motor 22 is fixedly connected to the outside of the mounting bracket 23, and the main bevel gear 24 is fixedly connected to one end of the motor 22.

[0046] The crushing assembly also includes a crushing cylinder 25, a crushing rod 26, and an auxiliary bevel gear 27;

[0047] The crushing cylinder 25 is rotatably connected to the lower part of one end of the mounting frame 23, the crushing rod 26 is rotatably connected to the upper part of one end of the mounting frame 23, the auxiliary bevel gear 27 is fixedly connected to the top of the crushing cylinder 25 and the crushing rod 26, and the main bevel gear 24 and the auxiliary bevel gear 27 are meshed.

[0048] The output shaft of the motor 22 is fixedly connected to the main bevel gear 24 via a coupling. There are two sets of auxiliary bevel gears 27. The two sets of auxiliary bevel gears 27 are fixedly connected to the top of the crushing cylinder 25 and the crushing rod 26 respectively. The crushing rod 26 passes through the inside of the crushing cylinder 25. The two sets of auxiliary bevel gears 27 are arranged vertically on one side of the main bevel gear 24.

[0049] Through the meshing between the mounting bracket 23 and the auxiliary bevel gear 27, the crushing cylinder 25 and the crushing rod 26 can be driven to rotate in both directions while the motor 22 is started to work.

[0050] Working principle: When workers crush copper ore;

[0051] First, the operator starts the motor 22 to work, which causes the output shaft of the motor 22 to drive the main bevel gear 24 to rotate through the coupling, and the main bevel gear 24 can drive the two sets of auxiliary bevel gears 27 on one side to mesh and connect.

[0052] Next, the crushing cylinder 25 and the crushing rod 26 equipped with the auxiliary bevel gear 27 can be rotated simultaneously, so that while the crushing cylinder 25 rotates forward, it drives the crushing rod 26 to rotate in reverse inside the crushing cylinder 25.

[0053] This step helps workers to uniformly crush the pre-treated copper ore, thereby improving the quality of the pre-treated copper ore.

[0054] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, also includes a sorting component;

[0055] The sorting assembly includes a slide rail 31, a collection box 32, a storage box 33, a filter plate 34, and a hydraulic cylinder 35;

[0056] The slide rail 31 is fixedly connected to the bottom of the distribution box 12, the collection box 32 is slidably connected to the inside of the slide rail 31, the storage box 33 is placed at the lower front end of the distribution box 12, the filter screen 34 is fixedly connected to the bottom inside of the distribution box 12, and the hydraulic cylinder 35 is fixedly connected to the rear end of the distribution box 12.

[0057] The sorting assembly also includes a telescopic rod 36, a pusher plate 37, and a guide plate 38;

[0058] The telescopic rod 36 is fixedly connected to one end of the hydraulic cylinder 35, the pusher plate 37 is fixedly connected to one end of the telescopic rod 36, and the guide plate 38 is fixedly connected to the front end of the distribution box 12.

[0059] The slide rail 31 is used to provide space for the collection box 32 to slide. The collection box 32 is horizontally and vertically arranged below the filter plate 34. The storage box 33 is horizontally and vertically arranged at the lower front end of the guide plate 38. The filter plate 34 and the pusher plate 37 are arranged on the same central axis.

[0060] With the auxiliary cooperation between the hydraulic cylinder 35 and the telescopic rod 36, the pusher plate 37 can be pushed by starting the hydraulic cylinder 35, so that the copper ore is screened through the filter plate 34 and the remaining copper ore is pushed into the storage box 33.

[0061] Working principle: When workers are grading copper ore;

[0062] First, the staff can start the hydraulic cylinder 35 to work, which can drive the telescopic rod 36 installed at one end to work, which can drive the pusher plate 37 to push repeatedly inside the distribution box 12, and push large copper ore particles through the guide plate 38 to the storage box 33.

[0063] Next, the small copper ore particles can be graded and fed into the collection box 32 with the assistance of the pusher plate 37 and the filter plate 34. At the same time, the collection box 32 in the slide rail 31 is pulled outward, which makes it convenient for the staff to take out the copper ore collected in the collection box 32.

[0064] This step helps workers screen the crushed copper ore and collect and handle the sorted copper ore.
