Technical Field
[0001] This utility model relates to the field of sand and gravel production technology, and in particular to an intelligent graded sand and gravel crushing production system. Background Technology
[0002] Sand and gravel crushers are widely used in mining, construction, cement, chemical, metallurgical and other industries. According to different structural forms, they are generally divided into impact crushers, cone crushers and jaw crushers. Among them, impact crushers rely on the impact and collision of materials on a high-speed rotating rotor to achieve crushing.
[0003] Currently, most existing sand and gravel crushing devices employ traditional crushing principles, such as impact crushing and compression crushing. While these devices can achieve sand and gravel crushing to a certain extent, they often struggle to crush the sand and gravel to finer particle sizes due to limitations in their crushing mechanisms. Therefore, we propose an intelligent grading sand and gravel crushing production system to address the aforementioned technical problems. Utility Model Content
[0004] In view of this, the present invention addresses the shortcomings of the present invention, and its main purpose is to provide an intelligent graded sand and gravel crushing production system, which aims to solve the above-mentioned problems.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: It includes a crushing box, a cover fixedly installed on the top of the crushing box, a motor fixedly installed on the cover, a rotating shaft fixedly connected to the inner side of the crushing box extending from the motor, an impact column and a crushing roller sequentially installed on the rotating shaft, the crushing roller located below the impact column, a first guide seat fixedly installed on the inner side of the crushing box near the cover, a first guide groove formed on the inner side of the first guide seat, a loading ring fixedly installed on the inner side of the crushing box below the first guide seat, impact strips evenly arranged on the inner side of the loading ring, a crushing cylinder fixedly installed on the inner side of the crushing box outside the crushing roller, first crushing strips evenly arranged on the inner side of the crushing cylinder, a discharge pipe connected to the bottom of the crushing box, and a third guide groove formed on the top of the crushing roller.
[0006] As a preferred embodiment, a second crushing strip is uniformly arranged on the outer side of the crushing roller, and the second crushing strip is in clearance fit with the crushing roller.
[0007] As a preferred embodiment, a second guide seat is fixedly provided inside the crushing box and between the crushing cylinder and the loading ring, and a second guide groove is provided on the inner side of the second guide seat.
[0008] As a preferred embodiment, a connecting seat is sleeved on the rotating shaft and located inside the crushing box, and the connecting seat is fixedly connected to the crushing box.

[0011] As a preferred embodiment, a loading frame is fixedly installed on the outside of the crushing box.
[0012] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, its main features are:
[0013] This device uses a motor fixedly mounted on the cover to drive a rotating shaft, thereby causing the sand and gravel to be crushed. The rotating shaft, extending from the motor and fixedly connected to the inside of the crushing chamber, loads and drives the impact columns and crushing rollers to rotate. The impact columns mounted on the rotating shaft initially crush the sand and gravel entering the crushing chamber. The sand and gravel continuously impact between the impact columns and the impact bars, thus achieving crushing. The crushing rollers mounted on the rotating shaft further crush the crushed sand and gravel, improving its fineness for subsequent use. A first guide seat, fixedly mounted inside the crushing chamber near the cover, cooperates with the inner side of the first guide seat... The first feed chute is used to guide the sand and gravel. After the sand and gravel enter the first feed chute, they are guided to the impact column for impact. The loading ring, which is fixedly installed inside the crushing box and below the first feed seat, and the impact strips, which are evenly arranged inside the loading ring, are used to block the sand and gravel that are ejected from the impact column. This allows the sand and gravel to continuously impact between the impact column and the impact strips, thereby achieving the crushing of the sand and gravel. The crushing cylinder, which is fixedly installed inside the crushing box and outside the crushing roller, is used to load the first crushing strip. The first crushing strip, which is evenly arranged inside the crushing cylinder, works with the crushing roller to further crush the sand and gravel, thereby achieving the desired fineness of the crushed sand and gravel.

[0022] Please see Figures 1 to 4 This utility model provides an intelligent graded sand and gravel crushing production system, including a crushing box 1. A cover 3 is fixedly installed on the top of the crushing box 1. A motor 6 is fixedly installed on the cover 3. The motor 6 extends to the inside of the crushing box 1 and is fixedly connected to a rotating shaft 8. An impact column 11 and a crushing roller 19 are installed sequentially on the rotating shaft 8. The crushing roller 19 is located below the impact column 11. A first guide seat 9 is fixedly installed on the inside of the crushing box 1 near the cover 3. A first guide groove 10 is opened on the inside of the first guide seat 9. A loading ring 13 is fixedly installed on the inside of the crushing box 1 and below the first guide seat 9. Impact strips 14 are evenly arranged on the inside of the loading ring 13. A crushing cylinder 17 is fixedly installed on the inside of the crushing box 1 and outside the crushing roller 19. First crushing strips 18 are evenly arranged on the inside of the crushing cylinder 17. A discharge pipe 7 connected to the crushing box 1 is provided at the bottom of the crushing box 1. A third guide groove 21 is opened on the top of the crushing roller 19.
[0023] In use, the cover 3 fixedly installed on the top of the crushing box 1 is used to enclose the crushing box 1. This facilitates the loading of the motor 6 and reduces the amount of sand and gravel ejected from the crushing box 1 during the crushing process. The motor 6 fixedly installed on the cover 3 drives the rotating shaft 8 to rotate, thereby promoting the crushing of sand and gravel. The rotating shaft 8, which extends from the motor 6 and is fixedly connected to the inside of the crushing box 1, loads the impact column 11 and the crushing roller 19 and drives them to rotate. The impact column 11 installed on the rotating shaft 8 is used to initially crush the sand and gravel entering the crushing box 1. The sand and gravel continuously impact between the impact column 11 and the impact bar 14, thereby achieving the crushing of sand and gravel. The crushing roller 19 installed on the rotating shaft 8 is used to further crush the crushed sand and gravel to improve the fineness of the sand and gravel for subsequent use. The first guide seat 9 fixedly installed on the inside of the crushing box 1 and near the cover 3, along with the first guide opening on the inside of the first guide seat 9, further contributes to the crushing process. The feed trough 10 is used to guide sand and gravel. After the sand and gravel enter the interior of the first feed trough 10, they are guided to the impact column 11 for impact. The loading ring 13, which is fixedly installed inside the crushing box 1 and located below the first feed seat 9, and the impact strips 14, which are evenly arranged inside the loading ring 13, are used to block the sand and gravel ejected from the impact column 11. This allows the sand and gravel to continuously impact between the impact column 11 and the impact strips 14, thereby achieving the crushing of the sand and gravel. The crushing cylinder 17 fixedly installed on the outside of the crushing cylinder 19 is used to load the first crushing bar 18. The first crushing bar 18, which is evenly arranged on the inner side of the crushing cylinder 17, works with the crushing roller 19 to crush the sand and gravel again, thereby achieving the fineness of the crushed sand and gravel. The discharge pipe 7, which is connected to the bottom of the crushing box 1, is used to discharge the crushed sand and gravel. The third guide chute 21, which is opened on the top of the crushing roller 19, is used to guide the sand and gravel, so that the crushed sand and gravel can be crushed again on the site.
[0024] Please see Figure 2 The outer side of the crushing roller 19 is uniformly provided with second crushing strips 20, and the second crushing strips 20 are fitted with the crushing roller 19 with a clearance.
[0025] When this device is in use, the second crushing strips 20, which are evenly arranged on the outer side of the crushing roller 19, are used to further crush the sand and gravel in conjunction with the first crushing strip 18. When the motor 6 is started, the motor 6 drives the rotating shaft 8 to rotate, and the rotating shaft 8 drives the crushing roller 19 to rotate. The crushing roller 19 crushes the sand and gravel between the two in conjunction with the first crushing strip 18, thereby improving the fineness of the crushed sand and gravel for its subsequent use.
[0026] Please see Figure 2A second guide seat 15 is fixedly provided inside the crushing box 1 and between the crushing cylinder 17 and the loading ring 13. A second guide groove 16 is provided on the inner side of the second guide seat 15.

Since the second guide groove 16 is conical, it can change the direction of movement of the sand and gravel and speed up the speed at which the sand and gravel are guided into the crushing cylinder 17 and the crushing roller 19, thereby improving the working efficiency of this device.
[0028] Please see Figure 2 A connecting seat 22 is sleeved on the rotating shaft 8 and located inside the crushing box 1, and the connecting seat 22 is fixedly connected to the crushing box 1.
[0029] When this device is in use, the connecting seat 22, which is sleeved on the shaft 8 and located inside the crushing box 1, is used to limit and support the shaft 8, so as to prevent the impact column 11 or the crushing roller 19 from being too heavy and affecting the crushing work of the impact column 11 and the crushing roller 19.
[0030] Please see Figure 4 The outer side of the striking column 11 is evenly provided with striking strips 12 corresponding to the striking strips 14;
[0031] When this device is in use, the striking bars 12, which are evenly arranged on the outer side of the striking column 11 and correspond to the impact bars 14, are used to cooperate with the impact bars 14 to initially crush the sand and gravel between them. When the motor 6 is started, the motor 6 drives the rotating shaft 8 to rotate, the rotating shaft 8 drives the striking column 11 to rotate, the striking column 11 drives the striking bars 12 to rotate, and the striking bars 12 drive the sand and gravel to impact the impact bars 14, thereby achieving initial crushing of the sand and gravel.
[0032] Please see Figure 1 The top of the cover 3 is provided with a feed inlet 4, and a baffle 5 is fixedly installed on the cover 3 and located outside the feed inlet 4.
