[0002] Ore is the most common resource on the market. In the mining process, ore is mined by professional equipment. The newly mined ore needs to go through processes such as crushing, beneficiation, and refining. When crushing, a special ore crusher is needed to crush it, thereby extracting the required minerals from the original ore.

[0003] However, most of the ore crushers in the prior art are divided into two types: open type and closed type. The open type is prone to stone splashing during crushing, and the closed type is difficult to clean inside the device. Both types have their own inconveniences when used, and it is difficult to uniformly classify the ore after crushing, causing inconvenience in subsequent processing;

[0004] In view of the above technical defects, a solution is now proposed. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that the ore crusher in the prior art cannot combine the prevention of stone splashing with the convenience of cleaning and cannot uniformly classify the crushed ore, and to propose an ore crusher with stone splash prevention function.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an ore crusher with a stone crushing and anti-splashing function, comprising a base, one side of the upper surface of the base is rotatably connected to a conveyor belt, one side of the conveyor belt is arranged on a support frame fixed to the upper surface of the base, a fixed box is fixed on the top of the support frame, an anti-splashing mechanism is installed inside the fixed box, the anti-splashing mechanism comprises two first rotating shafts rotatably connected to the inside of the fixed box, the outer layer of the first rotating shaft is sleeved with a protective cloth, one side of the protective cloth penetrates and extends to the outside of the fixed box to which a counterweight slide bar is fixed, the front end of the first rotating shaft penetrates and extends to the outside of the fixed box to which a first gear is fixed, and a first motor is fixed at the front end of one of the first gears;

[0007] The outer layer of one of the first rotating shafts is sleeved with a first bevel gear at the front and rear ends of the support frame, and a second bevel gear is arranged below the first bevel gear. A screw rod is fixed at the bottom of the second bevel gear, which passes through and extends to the front and rear ends of the support frame.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0013] 1. The utility model is provided with an anti-splash mechanism, which drives the two first rotating shafts to rotate through the first motor and the two first gears, thereby forming an unwinding effect on the protective cloth. As the protective cloth is unwound, the counterweight slide bar slowly descends to form a shield for the crushing roller. When the crushing roller is crushing the ore, protection is formed, and the rewinding is convenient. When not working, it is convenient to clean the inside of the device. One of the first rotating shafts rotates and cooperates with the two bevel gears to drive the screw to rotate. The screw sleeve is lifted and lowered by the screw sleeve. The lifting and lowering of the screw sleeve drives the pressure plate to lift and lower the ore to compress the ore, assist in crushing, make the ore fit the crushing roller more closely, and improve the crushing effect;

[0026] The outer layer of one of the first rotating shafts 12 is sleeved with the first bevel gear 11 at the front and rear ends of the support frame 6, and a second bevel gear 13 is arranged below the first bevel gear 11. A screw rod 15 that penetrates and extends to the inside of the front and rear ends of the support frame 6 is fixed at the bottom of the second bevel gear 13. A through groove is provided at the inner side of the front and rear ends of the support frame 6 corresponding to the position of the screw rod 15. The outer layer of the screw rod 15 is sleeved with a screw sleeve 14, and a pressure plate 16 is fixed between the two screw sleeves 14. A hard rubber pad is arranged at the bottom of the pressure plate 16 to buffer the splashed gravel and avoid damage caused by excessive impact. The inside of the base 1 is rotatably connected to two crushing rollers 4 at the position corresponding to the support frame 6. The inside of the crushing roller 4 is penetrated by a second rotating shaft 17, and the front end of the second rotating shaft 17 penetrates and extends to the outside of the base 1 where a second gear 18 is fixed, and the front end of one of the second gears 18 is connected to a second motor 19 fixed to the outside of the base 1.

[0027] The ore is transported to the position of the crushing roller 4 through the conveyor belt 2, and the first motor 7 is started to drive the two first gears 8 to rotate.

At the same time, the pressure of the pressure plate 16 keeps the ore close to the crushing roller 4 at all times.

[0030] Embodiment 2:

[0031] This embodiment aims to solve the problem that the ore crusher in the prior art is difficult to uniformly classify the ore after crushing, causing inconvenience in subsequent processing.

The crushed ore is collected through the collecting box and is convenient for subsequent removal, so that the ore can be uniformly classified for subsequent processing.

[0034] The crushed ore falls onto the upper surface of the screen plate 23, and the rotation of one of the second rotating shafts 17 drives the second pulley 28 to rotate, and the rotation of the second pulley 28 drives the belt 21 to rotate, and the rotation of the belt 21 drives the first pulley 20 to rotate, thereby driving the rotating roller 25 to rotate, and the rotating roller 25 drives the eccentric block 26 to move in a circle during the rotation, thereby driving the connecting rod 24 to shake, and the connecting rod 24 cooperates with the elastic sheet 27 to drive the screen plate 23 to form a vibration effect, so as to screen the crushed ore, and the larger ore is discharged through the guide plate 22, and the smaller ore falls into the base 1 for collection.
