Description

Technical Field

[0001] The present application relates to the technical field of mining machinery and equipment, and in particular to an integrated feeding and crushing machine. Background Art

[0002] Crusher is a common mining machinery and equipment, which is mainly used to crush stones. There are many types of crushers, such as jaw crusher, hammer crusher and impact crusher, which are all full-through equipment (that is, all materials are crushed by the crusher).

[0003] In the actual mining process, the rocks are mainly crushed by blasting, and then transported to the manufacturer for re-crushing. The staff put all the materials into the crusher for crushing. The size of the materials after blasting and crushing is different. For some small materials, re-crushing will result in smaller materials, resulting in a large amount of dust during the crushing process, and increasing the equipment operation cost. Summary of the invention

[0004] In order to reduce the dust phenomenon during the ore crushing process, the present application provides a feeding and crushing integrated machine.

[0005] The present application provides a feeding and crushing integrated machine adopts the following technical solution:

[0006] A feeding and crushing integrated machine comprises a frame and a crushing assembly, and also comprises a transmission and filtering assembly, wherein the transmission and filtering assembly comprises a plurality of conveying rollers arranged in parallel and at intervals along a material conveying direction, wherein the conveying rollers are rotatably connected to the frame, and the plurality of conveying rollers have the same rotation direction, and the crushing assembly is arranged at a position close to one end of a trajectory line in the material conveying direction and is located above the conveying rollers, and the crushing assembly is used to crush the material.

[0007] By adopting the above technical solution, multiple conveying rollers are arranged along the conveying trajectory of the material. When the multiple conveying rollers rotate synchronously, the material is placed on the conveying rollers. As the conveying rollers rotate, the material is transferred one by one on the multiple conveying rollers to realize the transportation of the material. At the same time, during the movement of the material, due to the gaps between adjacent conveying rollers, the smaller particles in the material can fall from the gaps, and the large materials are conveyed by the conveying rollers to the position of the crushing assembly for crushing, thereby realizing feeding and crushing. At the same time, the dust phenomenon caused by the re-crushing of small materials is reduced. The reduction in the number of crushed materials reduces the wear of the crushing assembly and reduces the operating cost of the equipment.

[0008] Optionally, a plurality of shifting blocks are arranged on the upper side wall of the conveying roller.

[0009] By adopting the above technical solution, the shifting block protrudes from the outside of the conveying roller, so that during the rotation of the conveying roller, on the one hand, the accumulated materials can be turned over to improve the filtering effect of the materials, and on the other hand, large materials can be pushed to move, which is convenient for the transportation of materials.

[0010] Optionally, the multiple conveying rollers are divided into multiple groups, including a transport roller group and a crushing matching roller group, and the transport roller group and the crushing matching roller group each include multiple conveying rollers arranged in a horizontal direction, the conveying rollers in the crushing matching roller group are lower in height than the conveying rollers in the transport roller group, and the crushing assembly is located above the crushing matching roller group.

[0011] By adopting the above technical solution, the crushing assembly crushes the material at the position of the crushing matching roller group. The height of the crushing matching roller group is lower than the transport roller group, so that the position of the crushing matching roller group forms a groove as a whole, which can prevent the material from splashing away from the crushing assembly during the crushing process, thereby improving the safety of the staff during the loading process.

[0012] Optionally, the crushing assembly includes a crushing roller rotatably connected to the frame and a driving member for driving the crushing roller to rotate, and the rotation direction of the crushing roller is opposite to the rotation direction of the conveying roller.

[0013] By adopting the above technical solution, as the conveying roller rotates, the material is transmitted to a position close to the crushing roller, and then under the action of the crushing roller and the conveying roller, the crushing roller squeezes and crushes the material, and then the material is discharged through the gap between the crushing roller and the conveying roller.

[0014] Optionally, the crushing roller includes a fixed shaft and a rotating cylinder, a movable hammer head is provided on the rotating cylinder, and the movable hammer head can slide along its own length direction, a knocking assembly is provided inside the rotating cylinder, and the knocking assembly includes a knocking block slidably arranged on one side of the movable hammer head along the length direction of the movable hammer head, and sliding the knocking block can make the knocking block hit the movable hammer head.

[0015] By adopting the above technical solution, during the material crushing process, the movable hammer head abuts against the material, and under the action of force, the movable hammer head squeezes the material to crush the material. During the process of the movable hammer head abutting against the material, the striking block hits the movable hammer head so that the movable hammer head hits the material, thereby improving the crushing effect on the material.

[0016] Optionally, the knocking assembly also includes a mounting block, which is fixed on the rotating cylinder, and the movable hammer head is mounted on the mounting block. A sliding cavity is opened on the mounting block at a position corresponding to the movable hammer head, and the knocking block is slidably fitted in the sliding cavity.

[0017] By adopting the above technical solution, a mounting block is arranged on the rotating cylinder to facilitate the installation of the movable hammer head. At the same time, the striking block is slidably matched in the sliding cavity to achieve a sliding connection between the striking block and the rotating cylinder.

[0018] Optionally, the striking assembly also includes a driving assembly, which includes a cylinder and a piston, an exhaust passage 45 connected to the outside is provided at a position of the sliding chamber near the movable hammer head, the piston is slidably fitted in the cylinder, an air pipe is provided between the cylinder and the mounting block, one end of the air pipe is connected to the inside of the cylinder, and the other end is connected to an end of the sliding chamber away from the movable hammer head.

[0019] By adopting the above technical solution, the piston movement can compress the air in the cylinder, and then squeeze the air into the sliding cavity. Under the action of pressure, the knocking block moves toward the direction close to the movable hammer head to knock the movable hammer head.

[0020] Optionally, the drive assembly also includes an eccentric piece and a connecting rod, the eccentric piece is fixed on the fixed shaft, the cylinder is radially arranged along the fixed shaft, one end of the connecting rod is fixed on the piston, and the other end is connected to the eccentric piece, and the rotation of the rotating cylinder can drive the end of the connecting rod close to the eccentric piece to move circumferentially along the eccentric piece, and the circumferential movement of the connecting rod along the eccentric piece can drive the piston to move.

[0021] By adopting the above technical solution, the eccentric piece is fixed on the fixed shaft to form an eccentric wheel structure or a cam structure. When the connecting rod moves along the circumference of the eccentric wheel, the position of the connecting rod relative to the fixed shaft changes, thereby driving the piston to move. In the process of rotating the rotating cylinder, the piston can move automatically, driving the knocking block to knock the movable hammer head.

[0022] Optionally, the knocking assembly also includes an energy storage assembly, which includes an extrusion ring and an air bag. An annular groove is opened inside the sliding cavity, and the extrusion ring is embedded in the annular groove. The extrusion ring is hollow inside and is made of flexible material. The extrusion ring can expand when gas is filled inside.

[0023] By adopting the above technical solution, after the knocking block corresponds to the extrusion ring, gas is introduced into the extrusion ring to expand it and tighten it against the knocking block, thereby limiting the knocking block. In this case, the piston moves, and the gas in the cylinder can be effectively compressed. As the pressure in the cylinder continues to increase, the knocking block can overcome the friction between the extrusion ring and the extrusion ring and separate from the extrusion ring. The gas pressure is released at the moment the knocking block separates from the extrusion ring, driving the knocking block to accelerate and hit the movable hammer head, thereby further improving the crushing effect.

[0024] Optionally, the energy storage component also includes an airbag, which is made of elastic material. The interior of the airbag is hollow and filled with gas. The airbag is connected to the interior of an extrusion ring. Applying a force to the airbag can cause the gas in the airbag to enter the extrusion ring. When the force on the airbag is removed, the airbag can rebound and recover.

[0025] By adopting the above technical solution, the airbag is squeezed, and the gas in the airbag is pressurized into the squeezing ring, which presses against the striking block to limit the striking block. When the force applied to the airbag is canceled, the airbag rebounds and automatically draws the air in the squeezing ring into the airbag, so that the squeezing ring is restored, which makes it easier for the striking block to return to the initial position (i.e., the position corresponding to the squeezing ring) after hitting the movable hammer head.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. The combination of multiple conveying rollers can, on the one hand, screen the raw materials before crushing and filter out the qualified materials in advance; on the other hand, it can convey the bulk materials forward to the crushing rollers for crushing, thereby reducing the material yield.

DETAILED DESCRIPTION

[0039] The following is combined with Figure 1-8 This application is described in further detail.

[0040] The embodiment of the present application discloses an integrated feeding and crushing machine.

[0041] Reference Figure 1 and Figure 2 A feeding and crushing integrated machine includes a frame 1, a transmission and filtering assembly 2 and a crushing assembly 3. The transmission and filtering assembly 2 and the crushing assembly 3 are both installed on the frame 1. The transmission and filtering assembly 2 is used to convey materials and screen and filter the materials, and the crushing assembly 3 is arranged above the transmission and filtering assembly 2 and is used to squeeze and crush the materials on the transmission and filtering assembly 2.

[0042] Reference Figure 1 and Figure 2 The transmission and filtering assembly 2 includes a plurality of conveying rollers 21 arranged along a trajectory line of a conveying direction. The conveying rollers 21 are rotatably connected to the frame 1. The plurality of conveying rollers 21 are connected by belts so that the plurality of conveying rollers 21 rotate in the same direction.

[0043] Reference Figure 1 and Figure 2During the material crushing process, the material is dumped onto a plurality of conveying rollers 21 through the transport equipment, and the rotation of the conveying rollers 21 can drive the material to be transferred on the plurality of conveying rollers 21. At the same time, due to the gaps between adjacent conveying rollers 21, the material with a smaller particle size can pass through the gaps between adjacent conveying rollers 21 and move downward, thereby achieving screening and filtering of the material. Large materials move to the corresponding position of the crushing assembly 3 under the action of the conveying rollers 21 for crushing. In this process, only large materials are crushed by the crushing device, which, on the one hand, reduces the occurrence of dust caused by the re-crushing of small materials, and on the other hand, reduces the degree of wear and operation cost of the equipment.

[0044] Reference Figure 1 and Figure 2 , a screening roller 211 is provided on the conveying roller 21, and the screening roller 211 is a disc-shaped structure. There are multiple screening rollers 211, and multiple screening rollers 211 are arranged at intervals along the length direction of the rotating shaft. A plurality of shifting blocks 212 are evenly spaced around the axis of the screening roller 211 on the side wall. The shifting blocks 212 can shift the material during the rotation of the conveying roller 21, which is convenient for the transportation of the material. The shifting blocks 212 on adjacent screening rollers 211 are staggered, which can also be understood as the shifting blocks 212 on the screening rollers 211 are arranged corresponding to the gaps between the shifting blocks 212 on adjacent screening rollers 211.

[0045] Reference Figure 1 and Figure 2 , multiple conveying rollers 21 are divided into multiple groups, including a conveying roller group 22, a guide roller group 23 and a crushing matching roller group 24. The conveying roller group 22, the guide roller group 23 and the crushing matching roller group 24 are arranged in sequence along the horizontal direction. The crushing matching roller group 24 includes two conveying rollers 21, and the height of the crushing matching roller group 24 is smaller than the height of the conveying roller group 22. The guide roller group 23 is used to guide the material on the conveying roller group 22 to move onto the crushing matching roller group 24. The multiple conveying rollers 21 in the guide roller group 23 are arranged in a downward tilt from a position close to the conveying roller group 22 to a position close to the crushing matching roller group 24 in the horizontal direction, so as to guide the movement of the material.

[0046] Reference Figure 1 and Figure 2The crushing assembly 3 is arranged above the crushing matching roller group 24, so that the height of the crushing assembly 3 can be effectively reduced, and then the height of the discharge port can be reduced, which is convenient for the staff to collect the crushed materials. Moreover, the transport roller group 22 is higher than the crushing matching roller group 24, which is convenient for the transport equipment to dump materials and reduce the dust caused by the material falling from a higher position or damage to the conveying roller 21. In addition, the arrangement trajectory of the multiple conveying rollers 21 of the transmission and filtering assembly 2 forms a groove at the position corresponding to the crushing matching roller group 24, which can reduce the splashing of materials in the direction away from the crushing assembly 3 during the extrusion process, and improve the safety of the equipment during use.

[0047] Reference Figure 1 and Figure 2 The transmission and filtering assembly 2 also includes a feeding slide 25, which is arranged on the side of the transport roller group 22 away from the crushing matching roller group 24, and the side of the feeding slide 25 close to the transport roller group 22 is inclined downward to guide the material on the feeding slide 25 to move to the transport roller group 22.

[0048] Reference Figure 1 and Figure 2 The crushing assembly 3 includes a crushing roller 31 and a driving member 32. The crushing roller 31 is rotatably arranged on the frame 1, and its axis is located between the axes of the two transmission rollers in the two crushing matching roller groups. The driving assembly 5 is used to drive the crushing roller 31 to rotate. The rotation direction of the crushing roller 31 is opposite to the rotation direction of the conveying roller 21. Under the cooperation of the conveying roller 21 and the crushing roller 31, the material passes through the gap between the crushing roller 31 and the conveying roller 21 to achieve extrusion and crushing of the material, and then discharged from the other side. In this embodiment, the driving member 32 is a reduction motor, and the output shaft of the reduction motor is connected to the crushing roller 31 through a coupling. The rotation of the output shaft of the reduction motor can drive the crushing roller 31 to rotate, thereby realizing the driving of the crushing roller.

[0049] Reference Figure 1 and Figure 2 The crushing roller 31 includes a connecting shaft 311 and a fixed cylinder 312. The connecting shaft 311 is rotatably connected to the frame 1, and the output shaft of the reduction motor is coaxially fixedly connected to the connecting shaft 311. The fixed cylinder 312 is fixedly sleeved on the connecting shaft 311, and a fixed hammer 313 is fixedly arranged on the outer wall of the fixed cylinder 312. The fixed hammer 313 is cylindrical as a whole, and a tip is arranged at one end. The length direction of the fixed hammer 313 is set at an acute angle with the tangent direction of the rotation of the crushing roller 31, so that the tip of the fixed hammer 313 can abut against the material to crush the material. The tip of the fixed hammer 313 is made of superhard material (such as corundum, silicon carbide, etc.) to reduce the damage of the fixed hammer 313.

[0050] The implementation principle of the integrated feeding and crushing machine of the present application is as follows: during the rock crushing process, the transport equipment dumps the material onto the feeding slide 25, and under the action of gravity, the material slides onto the conveying roller 21. As the conveying roller 21 rotates, the material continuously moves closer to the crushing roller 31. At the same time, the rotation of the conveying roller 21 can turn the material over, so that small particles in the material are separated from the gaps between adjacent conveying rollers 21, so that the small particles no longer pass through the crushing roller 31, reducing the occurrence of dust, and can reduce the situation where the crushing roller 31 grinds too fast.

[0051] Example 2

[0052] Reference Figure 1 and Figure 3 The difference between this embodiment and the first embodiment is that the structure of the crushing roller 31 is different. In this embodiment, the crushing roller 31 includes a fixed shaft 314, a rotating cylinder 315 and a movable hammer 316. The rotating cylinder 315 is rotatably sleeved on the fixed shaft 314, and the output shaft of the reduction motor is connected to the rotating cylinder 315 through a gear set. The movable hammer 316 has the same structure as the fixed hammer 313, which will not be described here. The movable hammer 316 is installed on the outer wall of the rotating cylinder 315. Rotating the rotating cylinder 315 can drive the hammer to move and achieve material crushing.

[0053] Reference Figure 3 and Figure 4 The movable hammer 316 is slidably connected to the rotating cylinder 315 in a direction parallel to its length direction, and a striking assembly 4 is arranged inside the rotating cylinder 315. The striking assembly 4 is used to strike the end face of the movable hammer 316 away from its tip, and the movable hammer 316 can impact the material under the action of force, thereby improving the crushing effect of the material.

[0054] Reference Figure 4 and Figure 5 The rotating cylinder 315 includes a connecting disk 3151 and a mounting cylinder 3152. The connecting disk 3151 is a disc-shaped structure. A through hole is provided in the connecting disk 3151 at a position corresponding to the fixed shaft 314. The connecting disk 3151 is rotatably sleeved on the fixed shaft 314. The mounting cylinder 3152 is a circular cylindrical structure. The mounting cylinder 3152 is sleeved outside the connecting disk 3151 and welded to the mounting cylinder 3152. An accommodating cavity is formed between the mounting cylinder 3152 and the fixed shaft 314, and the knocking assembly 4 is arranged in the accommodating cavity.

[0055] Reference Figure 5 and Figure 6The knocking assembly 4 includes a mounting block 41 and a knocking block 42. The mounting block 41 is arranged on the side wall of the mounting cylinder 3152, and the mounting block 41 is a rectangular block structure parallel to the length direction of the movable hammer head 316. One end thereof is arranged inside the mounting cylinder 3152, and is integrally formed with the mounting cylinder 3152. A mounting groove 43 is provided on the side of the mounting block 41 perpendicular to the length direction of the hammer head, and the hammer head is slidably installed in the mounting groove 43. The maximum distance that the movable hammer head 316 can slide is defined as L, L is not greater than 5mm, and L is 1mm in this embodiment to reduce the situation that the movable hammer head 316 vibrates greatly during the rotation of the rotating cylinder 315. A sliding cavity 44 is provided on one side of the mounting groove 43 close to the inside of the mounting cylinder 3152, and the sliding cavity 44 is connected to the mounting groove 43. The knocking block 42 slides in the sliding cavity 44 in a direction parallel to the sliding direction of the movable hammer head 316. The sliding knocking block 42 can make the knocking block 42 close to the movable hammer head 316, so that the movable hammer head 316 impacts the material again, which is convenient for crushing the material. The side wall of the mounting groove 43 is provided with an exhaust passage 45 connected to the outside, so that the knocking block 42 moves toward the direction close to the movable hammer head 316.

[0056] Reference Figure 5 and Figure 6 The mounting groove 43 and the sliding cavity 44 are both cylindrical grooves, and the diameter of the mounting groove 43 is larger than the diameter of the sliding cavity 44. A retaining ring 36 is provided on the side wall of the mounting groove 43 near the sliding cavity 44. The retaining ring 36 is coaxially arranged with the mounting groove 43 and is formed integrally with the side wall of the mounting groove 43. One end of the exhaust passage 45 forms an opening on the side wall of the mounting groove 43 near the sliding cavity 44, and the other end extends to the outside of the mounting block 41. Under the action of the retaining ring 36, the movable hammer head 316 can be prevented from fitting with the side of the mounting groove 43 near the sliding cavity 44, thereby reducing the occurrence of the movable hammer head 316 blocking the exhaust passage 45.

[0057] Reference Figure 4 and Figure 7 The knocking assembly 4 further includes a driving assembly 5, which includes a cylinder 51 and a piston 52. The cylinder 51 is a cylindrical shell structure with an opening at one end, which is arranged radially along the fixed shaft 314, and the opening faces the fixed shaft 314. The cylinder 51 is welded to the mounting cylinder 3152, and an air pipe 53 is arranged between the cylinder 51 and the mounting block 41. One end of the air pipe 53 is connected to the inside of the cylinder 51, and the other end is connected to the inside of the sliding chamber 44.

[0058] Reference Figure 4 and Figure 7, the end of the air pipe 53 connected to the cylinder 51 is defined as the air inlet end, and the end connected to the mounting block 41 is defined as the air outlet end. The air inlet end is located at the end of the piston 52 away from the fixed shaft 314, and the air outlet end is located at the side away from the movable hammer head 316 relative to the knocking block 42. The piston 52 moves, compressing the air inside the cylinder 51 into the sliding chamber 44, and under the action of air pressure, the knocking block 42 can be pushed to move and hit the movable hammer head 316. At the same time, when the piston 52 moves in the direction close to the fixed shaft 314, the knocking block 42 can move in the direction away from the movable hammer head 316.

[0059] Reference Figure 4 and Figure 5 The driving assembly 5 further includes an eccentric member 54 and a connecting rod 55. The eccentric member 54 is a disc-shaped structure. A through hole is provided on the eccentric member 54 for the fixed shaft 314 to pass through. The fixed shaft 314 is inserted into the through hole and fixedly connected to the eccentric member 54. The axis of the eccentric member 54 is parallel to the axis of the fixed shaft 314 and is spaced apart. Figure 1 In this embodiment, the axis of the eccentric member 54 is located below the axis of the fixed shaft 314 and is located on the side close to the feeding slide 25. One end of the connecting rod 55 is fixed to the piston 52, and the other end is connected to the side wall of the eccentric member 54, and can move along the circumferential direction of the eccentric member 54. During the overall rotation of the rotating cylinder 315, the connecting rod 55 is driven to rotate around the axis of the fixed shaft 314. Under the action of the eccentric member 54, the connecting rod 55 can slide in the cylinder 51, thereby realizing the automatic driving of the knocking block 42.

[0060] Reference Figure 4 and Figure 5 , during the overall rotation of the rotating cylinder 315, the movement of the piston 52 has two extreme positions, namely, the extreme position of the piston 52 close to the fixed shaft 314 and the extreme position away from the fixed shaft 314. When the axis of the piston 52, the axis of the eccentric 54 and the axis of the fixed shaft 314 are located in the same plane, and the eccentric 54 and the connecting rod 55 are located on the same side of the fixed shaft 314, it is the extreme position away from the fixed shaft 314, and the air in the cylinder 51 is compressed to the extreme position. The knocking block 42 moves to the extreme position close to the movable hammer head 316 accordingly, and knocks the movable hammer head 316. Similarly, when the piston 52 and the eccentric 54 are located on both sides of the fixed shaft 314 respectively, the piston 52 is located at the extreme position close to the fixed shaft 314, and the knocking block 42 moves to a position away from the movable hammer head 316.

[0061] Reference Figure 4 and Figure 7The driving assembly 5 further includes a guide column 56. The eccentric member 54 is provided with an annular guide groove 57 extending in its circumferential direction. The guide column 56 is a cylindrical structure. The guide column 56 is parallel to the axis of the eccentric member 54 and is slidably fitted in the guide groove 57. The end of the connecting rod 55 away from the piston 52 extends into the guide groove 57 and is welded to the guide column 56. An avoidance groove is provided on the side wall of the eccentric member 54 so that the connecting rod 55 can slide along with the guide rod. The connection between the connecting rod 55 and the eccentric member 54 is realized.

[0062] Reference Figure 5 and Figure 8 The knocking assembly 4 also includes an energy storage assembly 6, which includes an extrusion ring 61. An annular groove is provided on the side wall of the sliding chamber 44 at a position away from the movable hammer head 316. The inner side wall diameter of the extrusion ring 61 is larger than the diameter of the sliding chamber 44, and the extrusion ring 61 is embedded in the annular groove. The extrusion ring 61 is made of a flexible material. In this embodiment, the extrusion ring 61 is made of rubber. The extrusion ring 61 is hollow inside, and air is introduced into the extrusion ring 61 to expand it. When the knocking block 42 abuts against the extrusion ring 61, air is introduced into the extrusion ring 61 to expand it and abut against the knocking block 42. The friction between the rubber and the knocking block 42 can limit the knocking block 42 to a certain extent. During the overall rotation of the rotating cylinder 315, the piston 52 moves to compress the air inside the piston 52. By using the compression of air, energy is accumulated. When the pressure in the cylinder 51 is large enough, the knocking block 42 overcomes the friction between the extrusion ring 61 and the knocking block 42 and separates from the extrusion ring 61. The striking block 42 obtains acceleration at the moment of separation from the extrusion ring 61, so that the striking block 42 can quickly impact on the movable hammer head 316, further improving the crushing effect on the material.

[0063] Reference Figure 5 and Figure 8 The energy storage assembly 6 also includes an airbag 62. The airbag 62 is an annular structure as a whole. The inside of the airbag 62 is hollow and made of elastic material. The airbag 62 can be deformed after being subjected to pressure, and can automatically recover after the pressure is cancelled. The airbag 62 is sleeved on the outside of the cylinder 51, and the inside of the airbag 62 is filled with air. A connecting pipe is provided between the airbag 62 and the extrusion ring 61, and the two ends of the connecting pipe are respectively connected to the inside of the airbag 62 and the inside of the extrusion ring 61. When the airbag 62 is squeezed, the airbag 62 is deformed and the air inside the extrusion ring 61 is filled, so that the extrusion ring 61 expands. After the pressure is cancelled, the airbag 62 recovers, and the air inside the extrusion ring 61 enters the airbag 62, and then the extrusion ring 61 recovers, canceling the limit of the knocking block 42, so that the knocking block 42 is reset after knocking.

[0064] Reference Figure 5 and Figure 8The energy storage assembly 6 further includes an elastic member 63 and a pressure plate 64. The pressure plate 64 is an annular structure and is slidably sleeved on the cylinder barrel 51 along the length direction of the cylinder barrel 51, and is located on the side of the airbag 62 close to the fixed shaft 314. The elastic member 63 is arranged on the side of the pressure plate 64 close to the fixed shaft 314, and is used to apply a force to the pressure plate 64 to move the pressure plate 64 away from the fixed shaft 314. Under the action of the elastic member 63, the pressure plate 64 can automatically squeeze the airbag 62 to expand the squeezing ring 61. During the resetting process of the knocking block 42, the airbag 62 can be restored by moving the pressure plate 64 away from the airbag 62.

[0065] Reference Figure 5 and Figure 8 The energy storage assembly 6 further includes a linkage rod 65, one end of which is welded to the inner wall of the pressure plate 64, and the other end of which extends into the cylinder 51. When the piston 52 moves from the extreme position away from the fixed shaft 314 to the process of being close to the fixed shaft 314, it can abut against the linkage rod 65, and drive the linkage rod 65 close to the fixed shaft 314, thereby driving the pressure plate 64 close to the fixed shaft 314. When the piston 52 moves to the extreme position close to the fixed shaft 314, the airbag 62 can be completely restored.

[0066] Reference Figure 4 and Figure 5 In the actual crushing process, when the piston 52 is in the extreme position close to the fixed shaft 314, the extrusion ring 61 is in a normal state (i.e., not filled with too much gas), and the airbag 62 is in a normal state (i.e., not squeezed). At this time, the end of the sliding cavity 44 close to the movable hammer head 316 extends upward. The rotating cylinder 315 is rotated, and the piston 52 moves to initially compress the air in the cylinder 51, while the knocking block 42 is in a relatively fixed position under the action of gravity. With the movement of the piston 52, the pressure plate 64 squeezes the airbag 62 under the action of the elastic member 63, so that the extrusion ring 61 expands and presses against the knocking block 42 to limit the knocking block 42.

[0067] Reference Figure 4 and Figure 5 , the rotating cylinder 315 continues to rotate, and the air in the cylinder 51 continues to be compressed. When the piston 52 moves to the extreme position away from the fixed shaft 314, the pressure in the cylinder 51 is at the maximum value, and the knocking block 42 overcomes the friction between the extrusion ring 61 and the knocking block 42, thereby separating from the extrusion ring 61. After the knocking block 42 separates from the extrusion ring 61, the resistance it encounters suddenly changes, and it obtains acceleration, thereby impacting the movable hammer head 316 so that the movable hammer head 316 impacts the material. Subsequently, the piston 52 moves in the direction close to the fixed shaft 314, and negative pressure is generated in the cylinder 51, so that the knocking block 42 is reset to the position corresponding to the extrusion ring 61. At the same time, after the piston 52 abuts against the linkage rod 65, it drives the pressure plate 64 to move, and the extrusion ring 61 is restored, which facilitates the reset of the knocking block 42.

[0068] The implementation principle of the integrated feeder and crusher according to the embodiment of the present application is as follows: during the material crushing process, the movable hammer head 316 abuts against the material, and at the same time, the striking block 42 strikes the movable hammer head 316, so that the hammer head impacts the material, thereby improving the crushing effect on the material.

[0069] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
