Description

Technical Field

[0001] The present invention relates to the technical field of sand making machines, and in particular to a multi-stage pounding hard rock sand making machine. Background Art

[0002] The machine-made sand and gravel industry is an important basic industry in my country, and plays an important supporting role in the country's infrastructure construction. With the gradual scarcity of natural sand resources and the urgent need for environmental protection, it has become an industry trend to replace natural sand with machine-made sand. At present, machine-made sand has been widely used. Machine-made sand comes from rocks. Rocks are crushed and screened by mining equipment to make small particles with a particle size of less than 4.75mm. As the requirements for the fineness modulus, grading, powder content, and needle-like content of machine-made sand become higher and higher, the requirements for sand making equipment are also getting higher and higher.

[0003] The existing sand making equipment mainly includes hammer crusher, vertical shaft impact crusher, double roll crusher and so on.

[0004] The hammer crusher drives the rotor to rotate at high speed through the motor. After the material enters the crushing chamber, it is impacted, sheared and torn by the high-speed hammer head until it is crushed to the required particle size and finally discharged through the bottom screen plate.

[0005] The vertical shaft impact crusher consists of a rotor, an impact plate, etc. The material collides repeatedly between the rotor and the impact plate and is crushed into the required particle size through the action of centrifugal force and gravity.

[0006] The double-roll crusher uses two rollers rotating in opposite directions to squeeze and shear the material, and the material is crushed to the required particle size between the rollers.

[0007] In summary, the existing sand making machines still have the following technical problems: the hammer crusher has the problems of high sand powder content and severe hammer head wear, which leads to increased equipment maintenance costs and difficulty in maintaining stable crushing efficiency; although the vertical shaft impact crusher can provide better particle shape in the sand making process, it faces the challenges of high sand powder content and high power consumption, which increases production costs; and the double-roll crusher has poor sand particle shape and low output, which makes it difficult to meet the needs of large-scale and efficient production, thus affecting the overall production efficiency and product quality. These problems are common in different crushing equipment. Therefore, it is necessary to propose a multi-stage pounding hard rock sand making machine to provide a new technical solution to solve the technical problems mentioned in the above patents.

[0026] As described in the background art, the hammer crusher has problems of relatively high sand powder content and serious wear of the hammer head, resulting in an increase in equipment maintenance costs and difficulty in maintaining stable crushing efficiency; although the vertical shaft impact crusher can provide better particle shape during sand making, it faces challenges of relatively high sand powder content and high power consumption, increasing production costs; while the roll crusher has poor sand particle shape and low output, making it difficult to meet the needs of large-scale and high-efficiency production, thus affecting the overall production efficiency and product quality. These problems are common in different crushing equipment.

Wave-shaped chambers are provided on the surfaces of both the moving jaw 10 and the rotor 12, and the wave-shaped chambers on the surfaces of the moving jaw 10 and the rotor 12 mesh with each other.

[0030] In the multi-stage spring pressing hard rock sand making machine provided by the present invention, by setting the moving jaw 10 to rotate in cooperation with the rotor 12, the wave-shaped chambers on their surfaces cooperate and extrude with each other, and the chamber space gradually decreases from top to bottom, completing multiple crushing effects of multi-stage simultaneous crushing, extrusion and rubbing in one crushing action. The crushing efficiency is higher, the crushing effect is better, it can be competent for hard rock sand making, and the power consumption and wear are small.

[0031] To enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings.

[0032] Please refer to Figure 2 - Figure 3 , the multi-stage spring pressing hard rock sand making machine includes a body support frame 1, and a feed hopper 2 is arranged at the top of the body support frame 1;

[0033] Inside the body carrier 1, a rotor 12 is rotatably arranged. On one side of the rotor 12 inside the body carrier 1, a moving jaw 10 is arranged. Wave-shaped chambers are provided on the surfaces of both the moving jaw 10 and the rotor 12, and the wave-shaped chambers on the surfaces of the moving jaw 10 and the rotor 12 are meshed with each other.

[0034] Specifically, a squeezing rotating shaft 11 is rotatably connected inside the body carrier 1. The surface of the squeezing rotating shaft 11 is fixedly connected with a rotor 12. Wave-shaped chambers are arranged in an annular array on the surface of the rotor 12.

[0035] Specifically, a motor bracket 3 is fixedly connected to the side of the body carrier 1. A reduction motor 4 is fixedly connected to the top of the motor bracket 3. The driving end of the reduction motor 4 is rotatably connected with a driving pulley 5. A crushing rotating shaft 6 is rotatably connected inside the body carrier 1 and the crushing rotating shaft 6 extends outside the body carrier 1. One end of the crushing rotating shaft 6 is fixedly connected with a flywheel 7. A transmission belt 8 is in transmission connection between the surfaces of the flywheel 7 and the driving pulley 5.

[0036] Specifically, an eccentric sleeve 9 is fixedly connected eccentrically to the surface of the crushing rotating shaft 6. The surface of the eccentric sleeve 9 is fixedly connected with a moving jaw 10. A wave-shaped chamber is arranged in an arc shape on the side of the moving jaw 10 close to the rotor 12.

[0037] Specifically, a rear support iron 13 is fixedly connected inside the body carrier 1. A rib plate 14 is slidably connected inside the rear support iron 13. One end of the rib plate 14 away from the rear support iron 13 is hinged to the side of the moving jaw 10 away from the rotor 12. The bottom surface of the rear support iron 13 is fixedly connected with a support frame 17. A guide plate 15 and a positioning plate 16 are fixedly connected inside the body carrier 1. A support frame 17 is slidably connected inside the support frame 17. The support frame 17 is respectively slidably connected inside the positioning plate 16 and a pull rod 18. A spring 19 is sleeved on the surface of the pull rod 18. The spring 19 is arranged between the support frame 17 and the positioning plate 16 and both ends of the spring 19 are fixedly connected with the support frame 17 and the pull rod 18 respectively.

[0038] Through the above structural design, the raw materials enter the interior of the machine body carrier 1 from the feed hopper 2. The drive extrusion rotating shaft 11 drives the rotor 12 to rotate. While the rotor 12 is rotating, it drives the material to be conveyed to one side of the moving jaw 10. At the same time, the reduction motor 4 is started to drive the crushing rotating shaft 6 to rotate through the transmission belt pulley 5, the flywheel 7 and the transmission belt 8. While the crushing rotating shaft 6 is rotating, it drives the eccentric sleeve 9 to rotate. The rotation of the eccentric sleeve 9 cooperates with the rib plate 14 and the pull rod 18 to pull the rotor 12 to drive the moving jaw 10 to swing. When the moving jaw 10 swings close to the rotor 12, the crushing cavity becomes smaller, compressing the material for crushing. When the moving jaw 10 swings away from the rotor 12, the crushing cavity becomes larger. Driven by the rotor 12 synchronously, the material enters the next-stage crushing cavity for crushing. Under the combined action of the rotation of the rotor 12 and the swing of the moving jaw 10, the material is subjected to spring pressing and crushing. The two sides of the wavy chamber present two different crushing modes, one side is extrusion crushing and the other side is rubbing crushing, so as to realize the efficient multi-stage crushing of the material.
