[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-8This embodiment provides a technical solution: a multi-stage crushing and sand making machine, including a primary crushing chamber 1, a secondary crushing chamber 2 arranged below the primary crushing chamber 1, a controller 16 arranged on the right side of the secondary crushing chamber 2, the input terminal of the controller 16 being electrically connected to an external power supply, and also including a drive mechanism 3; Drive mechanism 3: It includes a turntable 31 and an arc-shaped slider 36. The turntable 31 is respectively set at the front and rear ends inside the primary crushing chamber 1. Circular guide rails 7 are fixedly connected to the middle of the inner walls on both sides of the primary crushing chamber 1. The turntable 31 is rotatably connected to the interior of the adjacent circular guide rails 7. The turntable 31 and the adjacent circular guide rails 7 are rotatably connected by a cross roller slewing bearing. The unique cross raceway structure of the cross roller slewing bearing gives it high load-bearing capacity and stability. When an external load is applied to the slewing bearing, the rollers roll in the raceway, bearing axial load, radial load, and overturning moment, thereby realizing rotational motion. The cross roller slewing bearing preferably uses the cross roller slewing bearing with excellent sealing effect in the existing technology. The double-layer rubber sealing ring of the roller slewing bearing effectively prevents dust and moisture from intruding and passing through, achieving a seal between the turntable 31 and the adjacent circular guide rail 7. This prevents ore raw materials and dust from entering the arc-shaped chute 6 through the connection between the turntable 31 and the adjacent circular guide rail 7, and further prevents ore raw materials and dust from entering the drive chamber 1 8 or drive chamber 2 9 through the arc-shaped chute 6, thus protecting the transmission components of the drive mechanism 3. A main crushing roller 4 is rotatably connected between the middle of the two turntables 31. The rear end of the main crushing roller 4 passes through the rear end of the primary crushing chamber 1 and is rotatably connected to the rear end of the primary crushing chamber 1. Secondary crushing rollers 5 are rotatably connected to both the left and right ends between the two turntables 31. The two secondary crushing rollers 5 and the main crushing roller 4 are rotatably connected to the primary crushing chamber 1. The teeth of the crushing roller 4 are interlocked, preventing tooth collision during the periodic oscillation of the secondary crushing roller 5. Symmetrically distributed arc-shaped grooves 6 are provided at both ends of the primary crushing chamber 1, with the center of each groove located on the longitudinal central axis of the primary crushing roller 4. Arc-shaped sliders 36 are slidably connected to the interior of adjacent arc-shaped grooves 6, and their interiors are rotatably connected to the corresponding ends of adjacent secondary crushing rollers 5. The drive mechanism 3 also includes a drive handle 35, a drive disc 37, and a second motor 38. The second motor 38 is located at the front end of the primary crushing chamber 1. The rear end of the output shaft of the second motor 38 is fixedly connected to the drive disc 37, and the rear end of the drive disc 37 is fixedly connected to a drive column. The front end of the front turntable 31 is fixedly connected to a drive cylinder. The longitudinal central axes of the drive cylinder, the two turntables 31, and the main crushing roller 4 coincide. The middle part of the drive cylinder is rotatably connected to the middle part of the front inner wall of the primary crushing chamber 1. The front end of the drive cylinder is fixedly connected to the drive handle 35, and the drive handle 35 has a sliding groove inside, which is slidably connected to the drive column. The front end of the primary crushing chamber 1 is provided with a drive chamber 8. The drive handle 35, drive disc 37, drive column, and drive cylinder are all located inside the drive chamber 8. The drive chamber 8 provides an external protective barrier for the internal transmission components, ensuring the transmission performance of the internal transmission components. The input end of the second motor 38 is electrically connected to the output end of the controller 16. The controller 16 realizes the operation of the second motor 38. The rotation of the output shaft of the second motor 38 drives the drive disc 37 to rotate.The drive disc 37 rotates, causing the drive column to rotate around the central axis of the output shaft of motor 38. When the drive column rotates to the left, it moves the drive handle 35 to the left, causing the drive cylinder to rotate clockwise. The rotation of the drive cylinder causes the front turntable 31 to rotate clockwise. Under the linkage of the two secondary crushing rollers 5 and the main crushing roller 4, the rear turntable 31 follows suit and rotates clockwise. The turntables 31 all rotate clockwise inside the corresponding circular guide rails 7. The two secondary crushing rollers 5 rotate clockwise around the central axis of the drive cylinder. When the drive column rotates to the right, it moves the drive handle 35 to the right, causing the drive cylinder to rotate counterclockwise. The rotation of the drive cylinder causes the front turntable 31 to rotate counterclockwise. Under the linkage of the primary crushing roller 5 and the main crushing roller 4, the rear turntable 31 rotates counterclockwise. Both turntables 31 rotate counterclockwise within their corresponding circular guide rails 7. The two secondary crushing rollers 5 rotate counterclockwise around the central axis of the drive cylinder. As the drive column rotates in a circular motion, it slides within the groove inside the drive handle 35, causing the drive cylinder to oscillate periodically. This, in turn, causes the two turntables 31 to oscillate periodically, ultimately resulting in the periodic oscillation of the two secondary crushing rollers 5. The periodic oscillation of the secondary crushing rollers 5 during their rotation increases the extrusion pressure on the ore raw material, improving the crushing efficiency. Simultaneously, it prevents the ore raw material from getting stuck inside the primary crushing unit, thus improving the feeding efficiency of the ore raw material during the crushing process. The drive mechanism 3 includes a drive gear 32, driven gears 33, and a motor 34. The drive gear 32 is fixedly connected to the rear end of the main crushing roller 4. The two driven gears 33 are fixedly connected to the rear end of the secondary crushing roller 5, and both driven gears 33 mesh with the drive gear 32. A drive chamber 9 is located at the rear end of the primary crushing chamber 1. The drive gear 32 and the two driven gears 33 are located inside the drive chamber 9. The drive chamber 9 provides an external protective barrier for the drive gear 32 and the two driven gears 33, ensuring their transmission performance. The motor 34 is... At the rear end of the primary crushing chamber 1, the front end of the output shaft of motor 34 is fixedly connected to the rear end of the main crushing roller 4. The input end of motor 34 is electrically connected to the output end of controller 16. Controller 16 enables motor 34 to operate. The rotation of the output shaft of motor 34 drives the main crushing roller 4 to rotate. The rotation of the main crushing roller 4 drives the drive gear 32 to rotate. The rotation of the drive gear 32 drives the two driven gears 33 to rotate. The rotation of the two driven gears 33 drives the adjacent secondary crushing roller 5 to rotate. The two secondary crushing rollers 5, the main crushing roller 4, and the inner walls of the left and right sides of the primary crushing chamber 1 support and squeeze each other to achieve the primary crushing of the ore raw material. The secondary crushing chamber 2 is rotatably connected to a main crushing roller 10. Three secondary crushing rollers 11 are rotatably connected to the secondary crushing chamber 2, and each secondary crushing roller 11 is fitted with the main crushing roller 10. An arc-shaped screen plate 12 is provided inside the secondary crushing chamber 2. The arc-shaped screen plate 12 has evenly distributed screen holes inside. Each secondary crushing roller 11 is fitted with the arc-shaped screen plate 12. A drive gear 15 is fixedly connected to the front end of the main crushing roller 10. Driven gears 14 are fixedly connected to the front ends of each of the three secondary crushing rollers 11, and each driven gear 14 meshes with the drive gear 15. The front end of the secondary crushing chamber 2 is... With a protective cover, the three driven gears 14 and the drive gear 15 are all located inside the protective cover to prevent external impurities from affecting the transmission performance of the three driven gears 14 and the drive gear 15. The rotation of the main crushing roller 10 drives the drive gear 15 to rotate, and the rotation of the drive gear 15 drives the three driven gears 14 to rotate. The rotation of the three driven gears 14 drives the adjacent secondary crushing roller 11 to rotate. The main crushing roller 10, the secondary crushing roller 11 and the arc screen plate 12 support each other and squeeze each other to achieve secondary crushing of the ore raw material. The ore raw material crushed to the specified degree continues to fall through the screen holes inside the arc screen plate 12, and then is discharged through the collection bucket at the lower end of the secondary crushing chamber 2. Among them: the rear end of the secondary crushing chamber 2 is equipped with a motor 3 13. The front end of the output shaft of the motor 3 13 is fixedly connected to the rear end of the main crushing roller 2 10. The input end of the motor 3 13 is electrically connected to the output end of the controller 16. The controller 16 realizes the operation of the motor 3 13. The rotation of the output shaft of the motor 3 13 drives the main crushing roller 2 10 to rotate.

[0017] The working principle of the multi-stage crushing and sand making machine provided by this utility model is as follows: During operation, the operator first places the primary crushing chamber 1, the secondary crushing chamber 2, and other mechanisms stably in the horizontal working area. After stable placement, the operator injects ore raw materials into the primary crushing chamber 1. The controller 16 activates the motor 34, and the output shaft of the motor 34 rotates, driving the main crushing roller 4 to rotate. The rotation of the main crushing roller 4 drives the drive gear 32 to rotate, which in turn drives two driven gears 33 to rotate. The rotation of the two driven gears 33 drives the adjacent secondary crushing rollers 5 to rotate. The two secondary crushing rollers 5, the main crushing roller 4, and the inner walls of the left and right sides of the primary crushing chamber 1 support and compress each other, achieving the initial crushing of the ore raw materials. Simultaneously, controller 16 activates motor 38. The output shaft of motor 38 rotates, driving drive disc 37 to rotate. The rotation of drive disc 37 drives drive column to rotate around the central axis of output shaft of motor 38. When drive column rotates to the left, it moves drive handle 35 to the left, causing drive handle 35 to rotate clockwise. The rotation of drive cylinder causes front turntable 31 to rotate clockwise. Under the linkage of the two secondary crushing rollers 5 and the main crushing roller 4, rear turntable 31 follows and rotates clockwise. Turntable 31 rotates clockwise within the corresponding circular guide rail 7. Both secondary crushing rollers 5 rotate clockwise around the central axis of drive cylinder. When drive column rotates to the right, it moves drive handle 35 to the right, causing drive handle 35 to rotate counterclockwise. The drive cylinder rotates, causing the front turntable 31 to rotate counterclockwise. Under the linkage of the two secondary crushing rollers 5 and the main crushing roller 4, the rear turntable 31 also rotates counterclockwise. Both turntables 31 rotate counterclockwise within their corresponding circular guide rails 7. The two secondary crushing rollers 5 rotate counterclockwise around the central axis of the drive cylinder. As the drive column rotates in a circular motion, it slides within the groove of the drive handle 35, causing the drive cylinder to oscillate periodically. This oscillation causes the two turntables 31 to oscillate periodically, ultimately resulting in the periodic oscillation of the two secondary crushing rollers 5. The periodic oscillation of the secondary crushing rollers 5 during their rotation increases the extrusion pressure on the ore raw material, improving the crushing efficiency while preventing the ore raw material from getting stuck in the primary crusher. Inside the unit, the feeding efficiency of the ore raw material during the crushing process is improved. After the primary crushing, the ore raw material enters the interior of the secondary crushing chamber 2. The controller 16 drives the motor 3 13 to operate. The output shaft of the motor 3 13 rotates, which drives the main crushing roller 2 10 to rotate. The rotation of the main crushing roller 2 10 drives the drive gear 2 15 to rotate. The rotation of the drive gear 2 15 drives the three driven gears 2 14 to rotate. The rotation of the three driven gears 2 14 drives the adjacent secondary crushing roller 2 11 to rotate. The main crushing roller 2 10, the secondary crushing roller 2 11 and the arc screen plate 12 support each other and squeeze each other to achieve secondary crushing of the ore raw material. The ore raw material crushed to the specified degree continues to fall through the screen holes inside the arc screen plate 12 and is then collected and discharged through the collection hopper at the lower end of the secondary crushing chamber 2.

[0018] It is worth noting that the controller 16 disclosed in the above embodiments controls the operation of motor 1 34, motor 2 38 and motor 3 13 using methods commonly used in the prior art.
