[0002] Crusher is primarily used to break up large rocks into smaller pieces, which can then be reused in production. Due to its high crushing efficiency and excellent crushing performance, crushers are increasingly favored by building material manufacturers. Crushers are used in industries such as construction, medicine, and mining. In the construction industry, crushers are primarily used to crush and process waste stone from buildings for reuse, reducing resource waste.

[0003] A common crusher consists of a crushing chamber, which is equipped with crushing rollers. These are usually arranged side by side. After the stone passes through the crushing rollers, they rotate to break up the larger pieces of stone, while the smaller pieces fall into the next chamber for further crushing or are directly screened. To ensure that the stone can fall properly, a relatively large gap is left between the two crushing rollers installed at the feed inlet. However, this also prevents the stone from fully contacting the rollers, resulting in larger pieces after crushing, which affects subsequent processing. Utility Model Content

DETAILED DESCRIPTION

[0022] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0023] according to Figure 1 、 2 As shown in Figures 3 and 3, a stone finishing and crushing equipment is proposed in this embodiment, including a crushing tank 1, a feed bin 8 is provided at the upper end of the crushing tank 1, and a discharge port 5 is provided at the lower end of the crushing tank 1; the stone is put into the crushing tank 1 through the feed bin 8 for crushing, and the crushed stone is discharged through the discharge port 5 at the lower end of the crushing tank 1.

[0024] A crushing chamber 2 and a discharge chamber 3 are provided in the crushing tank 1. The crushing chamber 2 is placed above the discharge chamber 3 and communicates with the discharge chamber 3. The discharge chamber 3 is communicated with the discharge port 5. Two feed bins 8 are provided at the upper end of the crushing chamber 2. The feed bins 8 are communicated with the crushing chamber 2. Two first crushing rollers 11 and two second crushing rollers 12 are arranged side by side in the feed bins 8. The second crushing rollers 12 are arranged obliquely below the first crushing rollers 11 and staggered with the first crushing rollers 11.

[0025] After the stone enters the feed bin 8, the two first crushing rollers 11 will perform preliminary crushing on the stone by rotating. The preliminary crushed stone will be ground for the second time by the second crushing roller 12 when passing through the second crushing roller 12. The second crushing roller 12 is set at an angle and staggered with the first crushing roller 11. The first crushing roller 11 and the second crushing roller 12 can form a more complex crushing trajectory in the feed bin 8, increase the contact area between the stone and the roller, and make the material be hit and squeezed multiple times during the crushing process, which helps to crush the material into smaller particles and improve the crushing efficiency.

[0026] A driving device for controlling the rotation of the first crushing roller 11 and the second crushing roller 12 is provided on the outside of the feed bin 8, and a grinding roller structure for crushing the gravel is provided in the crushing chamber 2.

[0027] The crushed stones will fall into the crushing chamber 2, and the grinding roller structure will further crush the stones.

[0028] For the specific structure of the grinding roller structure, please refer to the following description.

[0029] The grinding roller structure includes a conical grinding roller 7, a bracket 6 and a first motor 10. The first motor 10 is installed at the upper end of the crushing tank 1, and the conical grinding roller 7 is placed in the crushing chamber 2. The output end of the first motor 10 is fixedly connected to the upper end of the conical grinding roller 7, and the bracket 6 is fixedly connected to the inner side of the discharge chamber 3. The bracket 6 is rotatably connected to the lower end of the conical grinding roller 7. A gap is left between the crushing chamber 2 and the conical grinding roller 7 to allow stones to pass through, and the width of the gap decreases from top to bottom.

[0030] When the damaged stone is crushed for the second time, the stone that falls into the crushing chamber 2 will pass through the gap between the conical grinding roller 7 and the crushing chamber 2. The first motor 10 will drive the conical grinding roller 7 to rotate. The conical grinding roller 7 will rub against the stone during rotation to crush the stone. The width of the gap decreases from top to bottom. The further the stone falls, the smaller its particle size will be.

[0031] It should be further explained that a number of diamond-shaped protrusions 4 are provided on the inner wall of the grinding chamber 2 and the outer wall of the conical grinding roller 7. These protrusions 4 increase the roughness of the surfaces of the grinding chamber 2 and the conical grinding roller 7, enhancing friction between them and the stone. This increased friction contributes to better grinding of the stone. The friction and compression between the diamond-shaped protrusions 4 and the stone gradually refines the stone into smaller particles.

[0032] For the specific structure of the drive device, please refer to the following description.

[0033] The driving device includes a first driving member and a second driving member. The first driving member is installed outside the feed bin 8 and is used to control the two first crushing rollers 11 to rotate in the same direction. The second driving member is installed outside the feed bin 8 and is used to control the two second crushing rollers 12 to rotate in the same direction.

[0034] The first drive member includes a first bracket 13, which is fixedly connected to the outer wall of the feed bin 8. A second motor 15 is installed on the outside of the first bracket 13, and two gears 14 are installed on the inside of the first bracket 13. The two gears 14 are fixedly connected to the two first crushing rollers 11 via rotating shafts. The output shaft of the second motor 15 is fixedly connected to one of the gears 14, and the two gears 14 mesh with each other. The second motor 15 drives the gear 14 to rotate, and the rotation of the gear 14 also drives the other gear 14 to rotate. The first crushing roller 11 is fixed to the gear 14. When the gear 14 rotates, the first crushing roller 11 also rotates. The two first crushing rollers 11 rotate in the same direction, which facilitates the first crushing rollers 11 to crush the stone.

[0035] The second drive member includes a second bracket 16, which is fixedly connected to the outer wall of the feed bin 8. A third motor 18 is provided on the outer side of the second bracket 16, and two second gears 17 are provided on the inner side of the second bracket 16. The two second gears 17 are respectively fixedly connected to the two second crushing rollers 12 via rotating shafts. The output shaft of the third motor 18 is fixedly connected to one of the second gears 17. The working principle of the second drive member is the same as that of the first drive member, so it will not be described in detail here.

[0036] It should be further explained that the outer walls of the first and second crushing rollers 11, 12 are provided with a plurality of ribs, to which the first and second crushing rollers 11, 12 are fixedly connected. The ribs provided on the outer sides of the first and second crushing rollers 11, 12 also serve to increase the friction between the first and second crushing rollers 11, 12 when crushing stone. This increased friction helps to better crush the stone.

[0037] To prevent stones from splashing out of the upper end of feed bin 8 and endangering the safety of workers, a lift plate 9 is installed at the upper end of feed bin 8. One end of lift plate 9 is pivotally connected to the upper end of feed bin 8 via a cylindrical pin. After stones are dropped into feed bin 8, lift plate 9 is pulled to cover the upper end of feed bin 8. In addition to preventing stones from splashing out, lift plate 9 also serves as a dust barrier.

[0038] How this application works:

[0039] Stone is fed into the crushing tank 1 through the feed bin 8 for crushing. Once inside, the two first crushing rollers 11 rotate to initially crush the stone. The crushed stone then passes through the second crushing rollers 12, where it undergoes a secondary grinding process. The second crushing rollers 12 are tilted and staggered relative to the first crushing rollers 11. This creates a more complex crushing path within the feed bin 8, increasing the contact area between the stone and the rollers. This exposes the material to multiple impacts and compression during the crushing process, helping to break it into smaller particles and improving crushing efficiency. The crushed stone then falls into the grinding chamber 2, where the grinding rollers further crush it. The multiple crushes are then discharged through the discharge port 5 at the lower end of the crushing tank 1.
