[0031] The detection control box 2 is used to control the operation of the driving assembly 7, and can also detect the equipment temperature, processing speed, etc. during the crushing process to better monitor the working conditions of the equipment.

[0032] The storage frame 3 is used as a crushing bin and is based on a modular design, which is conducive to the maintenance of the components in the bin.

[0038] The bearing 82 is used to support the rotation process of the rotating shaft 81 so that it can maintain stable and smooth rotation. The crushing roller 83 and the crushing teeth 84 are used. When the two crushing rollers 83 rotate, the crushing teeth 84 are used to pull and tear the minerals to achieve the crushing purpose;

[0039] The modular crusher is assembled from five parts: a support component 1, a drive component 7, a storage frame 3, a crushing component 8 and a detection control box 2. In actual use, support components 1, storage frames 3 and crushing components 8 of different sizes or drive components 7 of different powers can be selected to adapt to different working scenarios and work requirements.

[0040] The movable limiting device 10 includes two sliding blocks 101 and three connecting seats 102. The sliding block 101 is slidably arranged in the sliding groove 5. The connecting seat 102 is connected to the side of the side wall comb plate 9 away from the crushing assembly 8. The sliding block 101 is connected to a sliding rod 104 outside. A sliding sleeve 105 is slidably arranged outside the sliding rod 104. A movable limiting plate 106 is arranged outside the two sliding sleeves 105.

[0041] The sliding block 101 and the sliding groove 5 are used. The sliding groove 5 guides the movement of the sliding block 101, so that the sliding block 101 and the movable limiting plate 106 can move stably in the vertical direction. The sliding rod 104 and the sliding sleeve 105 are used. The sliding rod 104 moves in the vertical direction along with the sliding block 101, so that the movable limiting plate 106 can move in the vertical direction and move closer to or away from the storage frame 3 at the same time.

[0042] A connecting groove 109 is opened on the connecting seat 102, and the movable limit plate 106 is located in the connecting groove 109. The width of the connecting groove 109 is greater than the width of the movable limit plate 106. The movable limit plate 106 is arranged outside the extrusion strip 6. One end of the sliding rod 104 is connected to a circular plate 107. The sliding rod 104 is outerly provided with a second elastic component 108. One end of the second elastic component 108 is connected to the sliding sleeve 105, and the other end of the second elastic component 108 is connected to the circular plate 107.

[0043] A second elastic component 108 is used to control the movable limiting plate 106 to move toward the storage frame 3 after the movable limiting plate 106 is separated from the extrusion bar 6. The movable limiting plate 106 cooperates with the extrusion bar 6, and the extrusion bar 6 squeezes the movable limiting plate 106 that moves downward, thereby controlling the movable limiting plate 106 to push the connecting groove 109 and the connecting seat 102 to move away from the storage frame 3. After the movable limiting plate 106 enters the connecting groove 109, the connecting seat 102 and the side wall comb plate 9 are limited.

[0044] A first elastic component 103 is connected to the bottom of the sliding block 101 , and the other end of the first elastic component 103 is connected to the inner wall of the sliding groove 5 . The sliding block 101 is configured to be an I-shaped shape.

[0045] The first elastic component 103 is used. When the movable limiting plate 106 is not subjected to an upward pulling force, the first elastic component 103 controls the movable limiting plate 106 and the sliding block 101 to automatically move downward, and prevents the movable limiting plate 106 from moving up and down at will;

[0046] The positioning and extrusion device 11 includes a movable pressure rod 111, which is slidably arranged in the limiting hole 12, and the movable pressure rod 111 is arranged on the movable connection device 14. A guide sleeve 112 is slidably arranged outside the movable pressure rod 111, and the guide sleeve 112 is penetrated and arranged on the storage frame 3. The movable pressure rod 111 is set to be a rectangle, and the top end of the movable pressure rod 111 is connected to the movable frame 113, and the bottom of the movable frame 113 is connected to the third elastic component 114, and the bottom end of the third elastic component 114 is connected to the storage frame 3.

[0047] A movable pressure rod 111 is used. When the movable pressure rod 111 enters the limiting hole 12, the connection limit between the side wall comb plate 9 and the storage frame 3 is realized. At the same time, the movable connection device 14 is squeezed during the downward movement of the movable pressure rod 111. The guide sleeve 112 is used to guide the vertical movement of the movable pressure rod 111. After the contact plate 115 is separated from the movable limiting plate 106, the third elastic component 114 automatically controls the movable pressure rod 111 to move downward.

[0048] A contact plate 115 is connected to the bottom of the movable frame 113 . The contact plate 115 is slidably disposed on the side of the storage frame 3 . The contact plate 115 can contact the movable limiting device 10 .

[0049] The movable connection device 14 includes a first elastic telescopic gas cylinder 141 and a second elastic telescopic gas cylinder 143. A connecting pipe 144 is provided between the first elastic telescopic gas cylinder 141 and the second elastic telescopic gas cylinder 143. The first elastic telescopic gas cylinder 141 is connected to the limiting hole 12, and the second elastic telescopic gas cylinder 143 is connected to the placement hole 13. An output contact end 142 is provided in the first elastic telescopic gas cylinder 141, and the output contact end 142 is arranged under the positioning and extrusion device 11. An output limiting end 145 is provided in the second elastic telescopic gas cylinder 143.

[0050] The first elastic telescopic gas cylinder 141 and the second elastic telescopic gas cylinder 143 are used to control the internal air pressure change and gas flow when being squeezed by the outside. When the external squeezing is lost, the output contact end 142 can move downward by the action of the moving pressure rod 111 and squeeze the internal gas of the first elastic telescopic gas cylinder 141;

[0051] The output limit end 145 and the middle groove 15 are used, and the output limit end 145 is inserted into the middle groove 15 to realize the connection between two adjacent side wall comb plates 9. The connecting pipe 144 is used for the flow of gas between the first elastic telescopic gas cylinder 141 and the second elastic telescopic gas cylinder 143.

[0052] Working principle of this utility model:

[0053] When the device is installed and used, according to the usage scenario, the coupling in the drive assembly 7 is controlled to disconnect from the rotating shaft 81 in the crushing assembly 8, and the position is adjusted to connect with the other side of the crushing assembly 8 to achieve double-sided or single-sided drive installation of the crusher.

[0054] After the modular assembly of the support component 1, the drive component 7, the storage frame 3, the crushing component 8 and the detection control box 2 is completed, the crushing component 8 can be driven by operating the drive component 7 to realize the operation of the crusher. When the side wall comb plate 9 needs to be replaced and maintained after long-term use, the movable limit plate 106 is directly pulled upwards. The movable limit plate 106 moves upward and separates from the connecting groove 109. At the same time, the moving process will squeeze the contact plate 115 and the movable frame 113 to move upward. When the movable frame 113 moves upward, it will drive the movable pressure rod 111 to separate from the output contact end 142 upward, and the movable pressure rod 111 separates from the limiting hole 12 upward, and the first elastic telescopic gas cylinder 141 and the second elastic telescopic gas cylinder 143 lose external extrusion and return to their original state. The output limiting end 145 in the second elastic telescopic gas cylinder 143 moves to the placement hole 13 and separates from the middle groove 15. At this time, the corresponding side wall comb plate 9 can be directly removed;

[0055] Put the new side wall comb plate 9 into the corresponding placement groove 4, then release the movable limit plate 106, the first elastic component 103 controls the sliding block 101 and the sliding rod 104 to move downward, and the sliding rod 104 controls the movable limit plate 106 to move downward through the sliding sleeve 105. At the same time, the movable limit plate 106 is pushed away from the storage frame 3 by the extrusion bar 6. After the movable limit plate 106 enters the connecting groove 109 downward, it applies a force to the connecting seat 102 and the side wall comb plate 9 to move away from the storage frame 3, so that the side wall comb plate 9 and The placement slots 4 are in stable contact, the movable limit plate 106 moves downward and separates from the contact plate 115, the elastic force of the third elastic component 114 controls the movable frame 113 and the movable pressure rod 111 to move downward into the limit hole 12 and squeeze the output contact end 142, and the gas in the first elastic telescopic gas cylinder 141 is squeezed and transferred to the second elastic telescopic gas cylinder 143 through the connecting pipe 144, and the air pressure in the second elastic telescopic gas cylinder 143 increases and controls the output limit end 145 to extend into the middle slot 15, so that the multiple side wall comb plates 9 are connected.
