[0030] To make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given in conjunction with the accompanying drawings of the specification

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below

[0032] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that may be included in at least one implementation manner of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it an individual or alternative embodiment that is mutually exclusive with other embodiments

[0033] Embodiment 1

[0034] Referring to Figures 1 - 10 , this is the first embodiment of the present invention. This embodiment provides a small crusher with automatic feeding. The small crusher with automatic feeding includes a crusher assembly 100, which includes a frame 101, a feeding mechanism 102 and a crushing mechanism 103. The feeding mechanism 102 is arranged on the frame 101, and the crushing mechanism 103 is arranged on the frame 101

[0035] The feeding mechanism 102 includes a feeding hopper 102a, a belt 102b, and a sieve plate 102c. The feeding hopper 102a is located on one side of the frame 101. The belt 102b is arranged inside the feeding hopper 102a, and the sieve plate 102c is fixed inside the feeding hopper 102a.

[0036] The feeding mechanism 102 can perform the feeding and pre-screening processes simultaneously. It relies on a vibration motor to generate vibration. When the vibration motor starts, the eccentric block inside it will rotate at high speed, thus generating a centrifugal force. This centrifugal force will cause the motor itself and the belt 102b connected to it to make a forced continuous circular or approximate circular motion. Furthermore, it will cause the stone materials to produce sliding and throwing motions on the belt 102b, enabling the stone materials to move forward continuously to achieve the purpose of feeding. The smaller stones and soil in the stone materials will pass through the sieve plate 102c, and the other stones will continue to pass over the sieve plate 102c and finally reach the crushing mechanism 103. This is the prior art, and this solution will not be elaborated much here, and those skilled in the art can clearly understand this working principle.

[0037] The crushing mechanism 103 includes a moving jaw plate 103a, a driving mechanism 103b, and a fixed jaw lower plate 103c. The moving jaw plate 103a is arranged on one side of the frame 101. The driving mechanism 103b is fixed on one side of the moving jaw plate 103a, and the fixed jaw lower plate 103c is fixed on one side of the frame 101.

[0038] Both the moving jaw plate 103a and the fixed jaw lower plate 103c are made of high-strength wear-resistant metal materials. The driving mechanism 103b is driven by transmission components such as an eccentric shaft, converting the circular motion of the eccentric shaft into the reciprocating swing motion of the moving jaw plate 103a. The moving jaw plate 103a and the fixed jaw lower plate 103c cooperate to achieve the extrusion and crushing of the stone materials. This is the prior art, and this solution will not be elaborated much here, and those skilled in the art can clearly understand this working principle.

[0039] The dredging assembly 200 is located on one side of the fixed jaw lower plate 103c and includes a moving part 201. The moving part 201 includes a fixed plate 201a, a moving column 201b, a fixed jaw upper plate 201c, a moving plate 201d, a motor 201e, a reciprocating roller 201f, a clamping block 201g, and an inclined block 201h. The fixed plate 201a is fixed on the frame 101. The fixed plate 201a is provided with a first moving groove 201a-1. The moving column 201b can slide in the first moving groove 201a-1. The fixed jaw upper plate 201c is sleeved outside the moving column 201b. The moving plate 201d is fixed on the moving column 201b. The motor 201e is arranged on the fixed plate 201a. The reciprocating roller 201f is arranged on one side of the motor 201e. The clamping block 201g is fixed on the moving plate 201d. The inclined block 201h is fixed on the fixed plate 201a.

[0040] The setting of the moving member 201 enables the fixed jaw upper plate 201c to translate and rotate the fixed jaw lower plate 103c, thereby changing the distance between the fixed jaw upper plate 201c and the moving jaw plate 103a, allowing the stone stuck between the two to find a loosening space during the change of the gap, move to a suitable crushing position, and smoothly complete the crushing work.

[0041] The rotating shaft of the motor 201e is connected to the reciprocating roller 201f. When the motor 201e rotates, it can drive the reciprocating roller 201f to rotate synchronously. The moving plate 201d is sleeved outside the reciprocating roller 201f, and the clamping block 201g slides in the spiral groove inside the reciprocating roller 201f. Through the cooperation of the clamping block 201g and the spiral groove, when the reciprocating roller 201f rotates, it can drive the moving plate 201d to perform a reciprocating motion along the direction of the reciprocating roller 201f, thereby driving the moving column 201b to move, and further driving the fixed jaw upper plate 201c to move horizontally. When the fixed jaw upper plate 201c moves to the position where it contacts the inclined block 201h, the inclined block 201h will squeeze the end face of the fixed jaw upper plate 201c, so that the fixed jaw upper plate 201c rotates around the moving column 201b, thereby changing the distance between the fixed jaw upper plate 201c and the moving jaw plate 103a, and applying a horizontal force to the stone, enabling the stone to find a loosening space during the change of the spacing, move to a suitable crushing position, and complete the crushing.

[0042] The motor 201e can be remotely controlled to start. The startup time of the motor 201e is fixed. In the initial state, the moving plate 201d is located at the middle position of the reciprocating roller 201f, and at the same time, the moving column 201b is located in the middle of the first moving groove 201a-1. At this time, the fixed jaw upper plate 201c and the fixed jaw lower plate 103c are in the same plane and aligned. When the motor 201e starts once and the moving plate 201d moves from the middle of the reciprocating roller 201f to both ends and then returns to the middle position of the reciprocating roller 201f, the fixed jaw upper plate 201c and the fixed jaw lower plate 103c are again in the same plane and aligned.

[0043] Embodiment 2

[0044] Refer to Figures 1 - 10 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0045] Specifically, the dredging component 200 further includes an auxiliary part 202, which is arranged on the fixed jaw upper plate 201c and includes a rotating shaft 202a, a lifting plate 202b, a rotating plate 202c, a disc 202d, a sliding rod 202e, a rotating sleeve 202f, a sleeve rod 202g and a connecting rod 202h. A rotating groove 201c-1 is formed in the fixed jaw upper plate 201c, and the rotating shaft 202a rotates in the rotating groove 201c-1. The lifting plate 202b is fixed on the rotating shaft 202a, the rotating plate 202c is fixed on the rotating shaft 202a, the disc 202d is fixed on one side of the reciprocating roller 201f, the sliding rod 202e is fixed on one side of the disc 202d, the rotating sleeve 202f is sleeved outside the sliding rod 202e, the sleeve rod 202g is fixed outside the rotating sleeve 202f, and the connecting rod 202h is connected to the outside of the sleeve rod 202g by a bearing.

[0046] The setting of the auxiliary part 202 is used to enhance the self-turning ability of the stone in the crushing cavity. The lifting plate 202b rotates upward from the bottom of the stone, driving the stone to rise.

[0047] When the motor 201e drives the reciprocating roller 201f to rotate, the disc 202d will rotate synchronously, so that the sliding rod 202e moves. Since the length of the connecting rod 202h remains unchanged, when the sliding rod 202e and the rotating sleeve 202f move, the end of the connecting rod 202h close to the rotating sleeve 202f will move along with the rotating sleeve 202f, and then the end of the connecting rod 202h close to the rotating plate 202c will move synchronously, and then the rotating plate 202c will rotate around the rotating shaft 202a, thereby driving the lifting plate 202b to rotate.

[0048] A through groove 201c-2 is formed in the fixed jaw upper plate 201c, and the lifting plate 202b slides in the through groove 201c-2. In the initial state, the lifting plate 202b is completely located in the through groove 201c-2. When the rotating plate 202c drives the rotating shaft 202a and the lifting plate 202b to rotate, the lifting plate 202b will rotate upward from the bottom of the stone, thereby applying an upward thrust to the stone, improving the self-turning ability of the stone, and moving the stone to a suitable crushing position.

[0049] Specifically, a sliding groove 202c-1 is formed in the rotating plate 202c, and a slider 202i is arranged in the sliding groove 202c-1. The connecting rod 202h is rotatably connected to the slider 202i.

[0050] The arrangement of the sliding groove 202c-1 ensures that when the upper fixed jaw plate 201c moves and rotates relative to the lower fixed jaw plate 103c, the motor 201e drives the disc 202d to rotate. At this time, the rotating sleeve 202f will slide on the sliding rod 202e. Since the connecting rod 202h is connected to the outside of the sleeve rod 202g through a bearing, when the upper fixed jaw plate 201c rotates to drive the rotating plate 202c and the connecting rod 202h to rotate synchronously, the slider 202i can slide in the sliding groove 202c-1. One end of the connecting rod 202h rotates relative to the slider 202i, and the other end can rotate relative to the sleeve rod 202g. Thus, when the upper fixed jaw plate 201c rotates, the rotation of the disc 202d can still drive the rotating plate 202c to rotate, thereby driving the lifting plate 202b to rotate without affecting the rotation of the upper fixed jaw plate 201c.

[0051] Specifically, the dredging assembly 200 further includes a locking member 203, which is arranged on one side of the upper fixed jaw plate 201c and includes a fixed block 203a, a stop block 203b, an extension block 203c and a locking block 203d. The fixed block 203a is fixed on the fixed plate 201a. A second moving groove 203a-1 is formed in the fixed block 203a. The stop block 203b slides in the second moving groove 203a-1. The extension block 203c is fixed on one side of the fixed block 203a. A sliding groove 203c-1 is formed in the extension block 203c. The locking block 203d slides on the sliding groove 203c-1. A locking groove 203b-1 is formed in the stop block 203b, and the locking block 203d can be engaged with the locking groove 203b-1.

[0052] There are two sets of locking members 203. Through the arrangement of the locking members 203, it is ensured that the upper fixed jaw plate 201c will not rotate randomly during normal crushing work.

[0053] There are two stop blocks 203b, which are symmetrically distributed near the two side edges of the upper fixed jaw plate 201c. The end face of the stop block 203b is attached to the end face of the upper fixed jaw plate 201c. The extension block 203c provides support and positioning for the locking block 203d. When the locking block 203d is engaged with the locking groove 203b-1, the positions of the two stop blocks 203b are locked, and the upper fixed jaw plate 201c cannot push the stop block 203b to move, so that the upper fixed jaw plate 201c cannot rotate. When the locking block 203d is not engaged with the locking groove 203b-1, the rotation of the upper fixed jaw plate 201c will push the stop block 203b to move along the second moving groove 203a-1, without hindering the rotation of the upper fixed jaw plate 201c.

[0054] Specifically, an extension plate 203e is fixed on one side of the moving plate 201d, an extension rod 203f is fixed on one side of the extension plate 203e, and the other end of the extension plate 203e is fixed to the locking block 203d.

[0055] The movement of the moving plate 201d will drive the extension plate 203e to move, thereby driving the extension rod 203f to move synchronously, and further driving the locking block 203d to move to control the locking of the stop block 203b.

[0056] In the initial state, the moving plate 201d is located at the middle position of the reciprocating roller 201f. At this time, both locking blocks 203d are engaged with the locking grooves 203b-1. Since there is a distance between the fixed jaw upper plate 201c and the inclined block 201h, when the motor 201e drives the reciprocating roller 201f to rotate, the movement of the moving plate 201d will first cause the locking block 203d to move, so that one of the locking blocks 203d is separated from the corresponding locking groove 203b-1, and the position of the corresponding stop block 203b is unlocked. After the two are separated, the fixed jaw upper plate 201c will contact the inclined block 201h and then cause the fixed jaw upper plate 201c to rotate. At this time, the end face of the fixed jaw upper plate 201c will squeeze the already unlocked stop block 203b, and the stop block 203b will not hinder the rotation of the fixed jaw upper plate 201c.

[0057] Specifically, a spring 203g is fixed on one side of the stop block 203b, and the other end of the spring 203g is fixed on the inner wall of the second moving groove 203a-1.

[0058] The spring 203g exerts a continuous thrust on the stop block 203b. When the end face of the fixed jaw upper plate 201c squeezes the stop block 203b, the spring 203g will be compressed. When the fixed jaw upper plate 201c moves away from the stop block 203b, the spring 203g will recover and drive the stop block 203b to contact the end face of the fixed jaw upper plate 201c again. At this time, the locking groove 203b-1 on the stop block 203b will move to the coaxial position with the locking block 203d again. When the moving plate 201d moves to the initial state, the locking block 203d will also be engaged with the locking groove 203b-1 again to limit the movement of the stop block 203b and prevent the fixed jaw upper plate 201c from rotating.

[0059] Embodiment 3

[0060] Refer to Figures 1 - 10 , which is the third embodiment of the present invention, and this embodiment is based on the first two embodiments.

[0061] Specifically, a torsion spring 201i is arranged outside the moving column 201b, and both ends of the torsion spring 201i are fixed to the moving column 201b and the fixed jaw upper plate 201c respectively.

[0062] When the fixed jaw upper plate 201c rotates around the moving column 201b under the extrusion of the inclined block 201h, the torsion spring 201i will be compressed. When the inclined block 201h no longer contacts and squeezes the fixed jaw upper plate 201c, the torsion spring 201i will recover, thereby driving the fixed jaw upper plate 201c to rotate and return to the initial state, so that the fixed jaw upper plate 201c and the fixed jaw lower plate 103c are in the same plane.

[0063] Specifically, there are two inclined blocks 201h, symmetrically distributed on both side edges of the fixed plate 201a.

[0064] Specifically, there are multiple lifting plates 202b, evenly distributed on the rotating shaft 202a.

[0065] There are two rotating plates 202c, and the two rotating plates 202c are connected by a connecting plate 202j, so that the two rotating plates 202c can move synchronously.

[0066] Specifically, the crusher assembly 100 further includes an innovative power mechanism 104, a main conveyor belt 105, a magnetic separator 106, a crawler 107, and a tailing conveyor belt 108. The innovative power mechanism 104 is arranged on one side of the crushing mechanism 103, the main conveyor belt 105 is arranged on the frame 101, the magnetic separator 106 is arranged on one side of the main conveyor belt 105, the crawler 107 is arranged on one side of the frame 101, and the tailing conveyor belt 108 is arranged on one side of the frame 101.

[0067] When the stone passes through the feeding mechanism 102, the fine stones pass through the sieve plate 102c and are conveyed out by the tailing conveyor belt 108. Other stones enter the crushing mechanism 103 for crushing. The crushed stones will be conveyed to the designated position through the main conveyor belt 105. The magnetic separator 106 can suck out the magnetic substances in the stones. The setting of the crawler 107 enables the entire crusher to move and adapt to various terrains. This is the prior art and will not be elaborated in this solution. And those skilled in the art can clearly understand the working principle.

[0068] During use, the stone enters the feeding hopper 102a. The stones that need to be crushed will pass through the sieve plate 102c and enter between the moving jaw plate 103a and the fixed jaw lower plate 103c. The extrusion and crushing of the stones are realized through the cooperation of the moving jaw plate 103a and the fixed jaw lower plate 103c. In the initial state, the fixed jaw upper plate 201c and the fixed jaw lower plate 103c are in the same plane and aligned, and the positions of the two side blocks 203b are locked, and the fixed jaw upper plate 201c will not rotate.

[0069] When a relatively large stone is stuck between the fixed jaw upper plate 201c and the moving jaw plate 103a, start the motor 201e to drive the reciprocating roller 201f to rotate synchronously, so that the moving plate 201d makes a reciprocating motion along the direction of the reciprocating roller 201f. The moving plate 201d drives the extension plate 203e and the extension rod 203f to move, so that the locking block 203d on one side is separated from the corresponding locking groove 203b-1, and the position of the corresponding stopper 203b is unlocked. After the two are separated, driven by the moving plate 201d, the moving column 201b will slide in the first moving groove 201a-1, and then drive the fixed jaw upper plate 201c to move. When the fixed jaw upper plate 201c moves to the position where it contacts the inclined block 201h, the inclined block 201h will squeeze the end face of the fixed jaw upper plate 201c, so that the fixed jaw upper plate 201c rotates around the moving column 201b. At this time, the end face of the fixed jaw upper plate 201c will squeeze the unlocked stopper 203b, and the stopper 203b will not hinder the rotation of the fixed jaw upper plate 201c. In this way, the distance between the fixed jaw upper plate 201c and the moving jaw plate 103a is changed, and a horizontal force is applied to the stone, so that the stone can find a loosening space during the process of the distance change and move to a suitable crushing position to complete the crushing.

[0070] At the same time, when the motor 201e drives the reciprocating roller 201f to rotate, the disc 202d will rotate synchronously, so that the slide rod 202e moves. Since the length of the connecting rod 202h remains unchanged, when the slide rod 202e and the rotating sleeve 202f move, the end of the connecting rod 202h close to the rotating sleeve 202f will move with the rotating sleeve 202f, and then the end of the connecting rod 202h close to the rotating plate 202c will move synchronously, and then the rotating plate 202c will rotate around the rotating shaft 202a, so as to drive the lifting plate 202b to rotate. The lifting plate 202b will rotate upward from the bottom of the stone, so as to apply an upward thrust to the stone, improve the self-turning ability of the stone, and make the stone move to a suitable crushing position.

[0071] As the motor 201e rotates, when the moving plate 201d moves to one end of the reciprocating roller 201f, the moving plate 201d will move in the opposite direction, so as to drive the fixed jaw upper plate 201c back to the middle position. When the inclined block 201h is separated from the fixed jaw upper plate 201c, the torsion spring 201i will return to its original state, so as to drive the fixed jaw upper plate 201c to rotate and return to the initial state, so that the fixed jaw upper plate 201c and the fixed jaw lower plate 103c are in the same plane. At the same time, the spring 203g will return to its original state and drive the stopper 203b to contact the end face of the fixed jaw upper plate 201c again. At this time, the locking groove 203b-1 on the stopper 203b will move to the coaxial position with the locking block 203d again. When the moving plate 201d moves to the initial state, the locking block 203d will also be engaged with the locking groove 203b-1 again to limit the movement of the stopper 203b and prevent the fixed jaw upper plate 201c from rotating, ensuring that the fixed jaw upper plate 201c will not rotate randomly during subsequent crushing work.
