Description

Technical Field

[0001] The invention relates to the technical field of crushing equipment, in particular to a vertical impact crushing device. Background Art

[0002] Impact crushers are widely used in the field of environmentally friendly building materials. Some common environmentally friendly building materials, such as building aggregates, road sand, artificial sand, etc., often need to be crushed by impact crushers. Specifically, impact crushers can crush hard materials such as limestone, quartz, coal, and ore into sand and gravel aggregates that meet the requirements. These aggregates are widely used in construction, roads, bridges and other projects. At the same time, the equipment can also process river pebbles, rocks, etc., and crush them into particles that meet construction needs. Therefore, impact crushers are indispensable and important equipment in the field of environmentally friendly building materials.

[0003] The materials crushed by the current impact crushing device usually contain particles of uneven sizes, and only particles that meet specific particle size requirements can be used in the production of environmentally friendly building materials. However, the existing impact crushing device cannot directly complete the screening work, and requires the help of additional screening equipment to achieve it. This means that after the crushing is completed, the staff needs to manually transfer the materials and perform secondary processing on the screening equipment. For those particles that do not meet the standards, that is, materials whose particle size does not meet the requirements, they need to be poured back into the impact crushing device for re-crushing. This process is not only cumbersome, but also greatly reduces production efficiency. In addition, frequent material transfer and re-crushing may also lead to material waste and energy consumption, which is not conducive to the sustainable development of environmentally friendly building materials.

The annular design of the feeding ring not only facilitates the uniform feeding of materials, but also ensures the stability of the entire device through the stable support of the column. The spacing ring effectively separates the feeding area and the crushing area, so that the materials can be lined up in order before crushing, avoiding the problems of material accumulation and blockage in traditional crushers. The reciprocating impact member uses high-speed reciprocating motion to perform an efficient impact crushing on the crushed material, laying a good foundation for the subsequent secondary crushing. Secondly, the outer cylinder rotates in one direction, and the rotating impact member rotates in another direction inside the outer cylinder. This The reverse rotation method not only enhances the crushing effect, but also enables the material to be more fully mixed and crushed in the crushing chamber. After one impact crushing, the material falls on the rotating impact component and is subjected to strong impact and shearing again, thereby achieving deep crushing and particle size refinement of the material. In addition, the built-in screening component realizes the integration of crushing and screening, greatly improving production efficiency. The screening component can accurately separate the materials that meet the particle size requirements, and the substandard materials are automatically returned to the delivery ring through the transmission component for re-crushing, forming a closed-loop crushing-screening-re-crushing process. The entire process does not require manual intervention, thereby reducing labor intensity and improving production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0058] Combination Figure 1-Figure 9 As shown, a vertical impact crushing device of the present invention comprises:

[0059] The delivery ring 1 is arranged in a ring shape as a whole, wherein four upright posts 2 are fixedly mounted on the outer wall of the delivery ring 1, and the other ends of the upright posts 2 are placed on the ground;

[0060] The spacer ring 3 is fixedly installed on the inner side of the delivery ring 1 and is coaxially arranged with the delivery ring 1, wherein the spacer ring 3 is used to separate the inner space of the delivery ring 1 into a feeding area and a crushing area;

[0061] The reciprocating impact member 4 is arranged inside the delivery ring 1 and located in the crushing area, and cooperates with the spacer ring 3 to perform a first impact crushing on the object to be crushed;

[0062] The outer cylinder 5 is arranged between the four columns 2 and located outside the delivery ring 1, and can be rotated and displaced in one direction outside the delivery ring 1;

[0063] The rotating impact member 6 is arranged inside the outer cylinder 5 and can be rotated and displaced in another direction inside the outer cylinder 5, wherein the objects to be crushed after the first impact crushing can fall on the rotating impact member 6, and the outer cylinder 5 and the rotating impact member 6 rotate in the opposite direction to perform the second impact crushing on the objects to be crushed;

[0064] The screening assembly 7 is arranged between the four columns 2 and below the outer cylinder 5, and is used to receive and screen the material to be crushed after two impact crushing operations;

[0065] The transmission component 8 is connected to the screening component 7 at one end and to the delivery ring 1 at the other end, and is used to transmit the unqualified to-be-crushed materials to the delivery ring 1 again for reciprocating crushing.

[0066] The material to be crushed is put into the feeding area of ​​the delivery ring 1. In the crushing area, the reciprocating impact component 4 starts to work and performs an impact crushing on the material to be crushed. The crushed material then falls onto the rotating impact component 6 on the inner side of the outer cylinder 5. At this time, the outer cylinder 5 rotates and displaces in one direction, while the rotating impact component 6 rotates and displaces in another direction inside the outer cylinder 5, forming a reverse rotation. This reverse rotation enables the rotating impact component 6 to perform a secondary impact crushing on the material to be crushed, further refining the particle size of the material. The material after two impact crushings then falls into the screening component 7. The screening component 7 receives the material to be crushed after two impact crushings and screens it. Among the screened materials, particles that meet the particle size requirements are separated, and particles that do not meet the standards are transmitted to the delivery ring 1 again through the transmission component 8 for reciprocating crushing.

[0067] In a preferred embodiment, the present invention can be further configured as follows: Figure 3 , Figure 5 As shown; the reciprocating impact member 4 includes:

[0068] The protective sleeves 41 are fixedly mounted on the inner side of the delivery ring 1, and the number of the protective sleeves 41 is not less than two and they are symmetrically distributed according to the center of the delivery ring 1;

[0069] The rack 42 is fixedly mounted on the inner side of the protective cover 41, and the number and distribution position of the rack 42 are adapted to the protective cover 41;

[0070] A first driving motor 43 is fixedly mounted on the surface of the frame 42 and an output end thereof passes through and extends to the other side surface of the frame 42, wherein a transmission shaft is fixedly mounted on the output end of the first driving motor 43;

[0071] A first cam 44 is fixedly mounted on the outer side of the transmission shaft;

[0072] A first transmission member 45 is slidably connected to the surface of the frame 42, wherein the first transmission member 45 can contact the outer surface of the first cam 44;

[0073] The second cam 46 is fixedly mounted on the outer side of the transmission shaft, wherein the first cam 44 and the second cam 46 are coaxially arranged;

[0074] A second transmission member 47 is fixedly mounted on a side surface of the first transmission member 45 away from the frame 42, and one end thereof is in contact with an outer surface of the second cam 46; and

[0075] A crushing plate 48 is fixedly mounted on an end portion of the first transmission member 45 away from the first cam 44. A plurality of first through holes are provided on the surface of the crushing plate 48. Driven by the first driving motor 43, the crushing plate 48 can be reciprocated vertically displaced to cooperate with the spacing ring 3 for reciprocating impact crushing. A protective sleeve 41 is fixedly mounted on the inner side of the delivery ring 1. The number of the protective sleeves 41 is not less than two and they are symmetrically distributed according to the center of the delivery ring 1, providing a stable installation foundation for the frame 42 and subsequent components. The frame 42 is fixedly mounted on the inner side of the protective sleeve 41. The number and distribution position of the frame 42 match the protective sleeve 41, ensuring the stability and reliability of the entire reciprocating impact component 4. A driving motor 43 is fixedly mounted on the surface of the frame 42, and its output end passes through and extends to the other side surface of the frame 42 to drive the transmission shaft to rotate. The first cam 44 and the second cam 46 are fixedly mounted on the outer side of the transmission shaft, and the two are coaxially arranged. This design enables the first cam 44 and the second cam 46 to rotate synchronously, but in opposite phases, providing a power basis for the subsequent reciprocating vertical displacement of the crushing plate 48. The first transmission member 45 is slidably connected to the surface of the frame 42 and can contact the outer surface of the first cam 44. When the first cam 44 rotates to contact with the first transmission member 45, it will push the first transmission member 45 to move. At this time, due to the phase relationship between the second cam 46 and the second transmission member 47, the second cam 46 does not contact the second transmission member 47, so it will not interfere with the displacement of the first transmission member 45. With the displacement of the first transmission member 45, the second transmission member 47 fixedly installed on the surface of the side away from the frame 42 will also move accordingly. When the second cam 46 rotates to contact the second transmission member 47, it will push the second transmission member 47 to move, thereby driving the first transmission member 45 and the crushing plate 48 to move downward. At this time, the first cam 44 does not contact the first transmission member 45, so it will not interfere with the downward movement of the crushing plate 48. The alternating action of 6 can reciprocately drive the crushing plate 48 to perform vertical displacement so as to extrude and impact the crushed objects. A plurality of first through holes are provided on the surface of the crushing plate 48. When the crushing plate 48 performs impact crushing, some small crushed objects can fall downward from these through holes to further refine the particle size of the materials. In order to ensure the stability of the first transmission member 45 during movement, a slide groove is provided on the surface of the frame 42, and a sliding block adapted to the slide groove is fixedly installed on the surface of the first transmission member 45. At the same time, rollers are provided at the ends of the first transmission member 45 and the second transmission member 47 to reduce the friction between the first cam 44 and the second cam 46 and extend their service life.

[0076] In a preferred embodiment, the present invention can be further configured as follows: Figure 1 , Figure 2As shown; a cross mounting frame 9 is fixedly installed on the surface of one side of the delivery ring 1 away from the ground, wherein a driving column 10 is provided through the center of the cross mounting frame 9, and the driving column 10 can rotate axially at the center of the cross mounting frame 9, and a second driving motor 11 is also fixedly installed on the surface of the cross mounting frame 9, and a first belt transmission assembly 12 is provided between the second driving motor 11 and the driving column 10, and the second driving motor 11 drives the driving column 10 to perform axial rotation displacement through the first belt transmission assembly 12, and a sealing cover 22 is fixedly installed on the inner side of the delivery ring 1, and the sealing cover 22 A feed port is provided on the surface, a toggle rod 13 is fixedly installed on the outer side of the driving column 10, and the toggle rod 13 is located between the sealing cover 22 and the spacer ring 3. A cross mounting frame 9 is fixedly installed on the surface of the side of the delivery ring 1 away from the ground, and a driving column 10 is penetrated through the center of the cross mounting frame 9. This driving column 10 can perform axial rotation displacement at the center of the cross mounting frame 9. In order to drive the driving column 10 to rotate, a second driving motor 11 is also fixedly installed on the surface of the cross mounting frame 9, and a second driving motor 11 is set between the second driving motor 11 and the driving column 10. A first belt transmission assembly 12 is provided, through which the second drive motor 11 can effectively drive the drive column 10 to rotate axially. A sealing cover 22 is fixedly installed on the inner side of the delivery ring 1. A feed port is provided on the surface of the sealing cover 22 for delivering the material to be crushed into the crushing device. A toggle rod 13 is fixedly installed on the outer side of the drive column 10. The toggle rod is located between the sealing cover 22 and the spacer ring 3. When the second drive motor 11 is started, it will drive the drive column 10 on the cross mounting frame through the first belt transmission assembly 12. 9 rotates at the center, and as the driving column 10 rotates, the toggle rod 13 fixed on the outside thereof will also rotate accordingly. During the rotation, the toggle rod 13 can effectively stir the object to be crushed located above the spacer ring 3, causing it to fall downward from the central hollow of the spacer ring 3 and enter the crushing area for crushing. At the same time, the use of the sealing cover 22 plays a vital role. It can not only prevent the object to be crushed from being thrown out of the inner side of the delivery ring 1 during the impact crushing process, but also effectively suppress the flying of dust, thereby ensuring the cleanliness and safety of the entire crushing process.

[0077] In a preferred embodiment, the present invention can be further configured as follows: Figure 1 , Figure 2As shown; the outer sides of the four columns 2 are fixedly installed with connecting legs 14, and the other ends of the four connecting legs 14 are fixedly connected to the first connecting ring 15, a transmission rod 16 is rotatably connected to the surface of one of the connecting legs 14, and the other end of the transmission rod 16 is rotatably connected to the driving column 10 through the second belt transmission assembly 24, a driving gear 17 is fixedly installed on the outside of the transmission rod 16, and a gear ring 18 that meshes with the driving gear 17 is fixedly installed on the outer side of the outer cylinder 5, wherein the outer cylinder 5 is rotatably connected to the inner side of the first connecting ring 15 by the driving gear 17 and the gear ring 18. The four columns 2 serve as the main supporting structure of the entire crushing device, and the outer sides of the four columns 2 are fixedly installed with connecting legs 14, and the other ends of the four connecting legs 14 are fixedly connected to the first connecting ring 15 to form a stable frame structure, which provides a solid foundation for subsequent transmission and rotation, and a transmission rod 16 is rotatably connected to the surface of a certain connecting leg 14 of the first connecting ring 15. The driving rod 16 has the other end connected to the driving column 10 through a second belt transmission assembly 24, which means that when the driving column 10 rotates under the drive of the second driving motor 11, it will drive the driving rod 16 to rotate accordingly through the second belt transmission assembly 24. A driving gear 17 is fixedly installed on the outside of the driving rod 16. At the same time, a gear ring 18 meshing with the driving gear 17 is fixedly installed on the outside of the outer cylinder 5. The meshing design of the gear and the gear ring enables the driving gear 17 to drive the gear ring 18 and the outer cylinder 5 fixed thereto to rotate when the driving rod 16 rotates. In order to ensure the stability and smoothness of the outer cylinder 5 during rotation, an annular slide rail is also fixedly installed on the inner side of the first connecting ring 15, and a sliding member matched with the annular slide rail is fixedly installed on the outer side of the outer cylinder 5. In this way, the outer cylinder 5 is more stably connected to the inner side of the first connecting ring 15 through the sliding connection between the annular slide rail and the sliding member.

[0078] In a preferred embodiment, the present invention can be further configured as follows: Figure 3 , Figure 4 and Figure 6 As shown; the rotating impact member 6 comprises:

[0079] The base 61 is fixedly mounted on the end of the driving column 10 and is located inside the outer tube 5;

[0080] The second connecting ring 62 is fixedly mounted on the outer side of the base 61 and is shaped like a trumpet as a whole. A plurality of second through holes 63 are processed on the surface of the second connecting ring 62;

[0081] The third connecting ring 64 is fixedly mounted on the large-diameter end of the second connecting ring 62;

[0082] A convex strip 65, one end of which is fixedly mounted on the surface of the third connecting ring 64, and the other end of which is fixedly connected to the base 61, wherein a plurality of convex strips 65 are provided and are equidistantly distributed in a ring shape according to the center of the base 61; and

[0083] The inner lining plate 66 is fixedly installed on the inner side of the outer cylinder 5. There are several lining plates 66 and they are equidistantly distributed in a ring shape according to the axis of the outer cylinder 5. A second connecting ring 62 arranged in a trumpet shape is fixedly installed on the outer side of the base 61. A plurality of second through holes 63 are processed on the surface of the second connecting ring 62. These through holes allow the objects to be crushed to pass through during the rotation and impact process, so as to achieve the crushing effect. A third connecting ring 64 is fixedly installed on the large-diameter end of the second connecting ring 62, which further enhances the structural stability of the rotating impact component 6. On the surface of the third connecting ring 64, there are several convex strips 65 fixedly installed. One end of these convex strips is connected to the third connecting ring 64, and the other end is fixedly connected to the base 61. The number of convex strips 65 is set to several and they are equidistantly distributed in a ring shape according to the axis of the outer cylinder 5. The ribs 65 are equidistantly distributed in a ring shape at the center of the base 61. This design enables the ribs 65 to effectively impact and crush the material to be crushed during rotation. At the same time, a number of inner lining plates 66 are fixedly installed on the inner side of the outer cylinder 5. These inner lining plates are equidistantly distributed in a ring shape according to the axis of the outer cylinder 5, forming a certain gap with the ribs 65. When the base 61 drives the second connecting ring 62, the third connecting ring 64 and the ribs 65 to rotate, the outer cylinder 5 rotates in another direction due to the mutual engagement of the driving gear 17 and the gear ring 18, and relative movement will be generated between the ribs 65 and the inner lining plates 66. This relative movement causes the material to be crushed to be subjected to strong impact and shear force under the action of the rotating impact component 6, thereby achieving the purpose of crushing.

[0084] In a preferred embodiment, the present invention can be further configured as follows: 1. Figure 8 As shown; the screening assembly 7 comprises:

[0085] The receiving tube 71 is disposed between the four columns 2 and below the outer tube 5;

[0087] The discharge pipe 73 is fixedly installed on the side surface of the supporting cylinder 71 close to the ground and is interconnected with the supporting cylinder 71. A valve is also arranged on the outer side of the discharge pipe 73. A screening net 72 is fixedly installed on the inner side of the supporting cylinder 71. The screening net is arranged in an inclined direction as a whole. Its inclination angle and the size of the screen holes are carefully designed to ensure that the material can flow smoothly during the screening process and effectively separate the fine particles that meet the particle size requirements from the oversized particles or impurities. When the material falls into the supporting cylinder 71 from the outer cylinder 5 and contacts the screening net 72, the fine particles will pass through the screen holes and fall into the bottom of the supporting cylinder 71, while the oversized particles or impurities will remain above the screening net. With the continuous addition of materials and the continuous screening, the fine particles that meet the particle size requirements will gradually accumulate at the bottom of the supporting cylinder 71 and are ready to be discharged through the discharge pipe 73. When the screened material needs to be discharged, it is only necessary to open the valve on the outer side of the discharge pipe 73, and the fine particle material will flow out smoothly under the action of gravity.

[0088] In a preferred embodiment, the present invention can be further configured as follows: Figure 1 , Figure 7As shown; four sliding sleeves 19 are fixedly installed on the outer side of the receiving tube 71, and the four sliding sleeves 19 are respectively slidably connected to the outer sides of the four columns 2. A sliding groove 20 is provided on the outer surface of the receiving tube 71, wherein the sliding groove 20 is arranged in a wave shape as a whole. A plurality of sliding limit rods 21 are fixedly installed on the outer side of the outer tube 5, wherein the end of the sliding limit rod 21 away from the outer tube 5 is slidably connected to the inner side of the sliding groove 20, and four sliding sleeves 19 are fixedly installed on the outer side of the receiving tube 71. These four sliding sleeves are respectively slidably connected to the outer sides of the four columns 2. Such a design enables the receiving tube 71 to slide up and down stably under the guidance of the columns 2. At the same time, a wavy sliding groove 20 is provided on the outer surface of the receiving tube 71. The design of this sliding groove provides a sliding trajectory for the subsequent sliding limit rod 21, and a plurality of sliding limit rods 21 are fixedly installed on the outer side of the outer tube 5. One end of these sliding limit rods is away from the outer tube 5, and the other end is slidably connected to the sliding groove 20 on the receiving tube 71 On the inside, when the outer cylinder 5 rotates under the meshing action of the driving gear 17 and the gear ring 18, it will drive the receiving cylinder 71 to move through the sliding limit rod 21. Since the sliding groove 20 is arranged in a wave shape as a whole, when the sliding limit rod 21 slides in the sliding groove 20, it will be guided by the wave-shaped trajectory, so that the receiving cylinder 71 will produce reciprocating displacement in the up and down directions. This reciprocating up and down displacement will drive the entire receiving cylinder 71 to shake, thereby enhancing the material screening effect on the screening net 72. Specifically, when the receiving cylinder 71 moves upward, the material on the screening net 72 will be subjected to a certain extrusion pressure, which helps fine particles to pass through the sieve holes and fall into the bottom of the receiving cylinder 71; when the receiving cylinder 71 moves downward, the material on the screening net will be subjected to a certain throwing force, which helps to shake off oversized particles or impurities from the screening net. In this way, through the reciprocating up and down displacement of the receiving cylinder 71 and the cooperation of the screening net, a more sufficient and effective screening of the material can be achieved.

[0089] In a preferred embodiment, the present invention can be further configured as follows: Figure 1 , Fig. 9 As shown; the transmission component 8 includes:

[0090] The housing 81 is fixedly mounted on the outer side of one of the connecting legs 14;

[0091] A transmission shaft 82, one end of which is rotatably connected to the inner side of the housing 81, and the other end of which penetrates and extends to the outer side of the housing 81;

[0092] The spiral conveying blade 83 is fixedly mounted on the outer side of the transmission shaft 82 and located on the inner side of the housing 81;

[0093] A feed hose 84, one end of which penetrates and extends to the inner side of the receiving tube 71, and the other end of which is connected to the outer shell 81; and

[0094] The discharge pipe 85 is connected to the outer shell 81 at one end, and the other end penetrates and extends to the inner side of the delivery ring 1. The outer shell 81 is fixedly installed on the outer side of one of the connecting legs 14, providing a stable support for the entire transmission assembly. One end of the transmission shaft 82 is rotatably connected to the inner side of the outer shell 81, and the other end penetrates and extends to the outer side of the outer shell 81 so as to be connected to an external driving device to realize the rotation of the transmission shaft. When the transmission shaft 82 rotates, it drives the spiral conveying blade 83 fixedly installed on the outer side thereof to rotate together. The spiral conveying blade 83 is located on the inner side of the outer shell 81, and its spiral design enables the blade to generate a rotation when the blade rotates. The thrust on the outer shell 81 is used to transport the material upward along the inner wall of the outer shell 81. One end of the feed hose 84 passes through and extends to the inner side of the receiving tube 71, and the other end is connected to the outer shell 81. In this way, the screened material in the receiving tube 71 can smoothly enter the outer shell 81 through the feed hose 84, and then be transported to the discharge pipe 85 by the spiral conveying blade 83. One end of the discharge pipe 85 is connected to the outer shell 81, and the other end passes through and extends to the inner side of the delivery ring 1. When the material is transported to the end of the outer shell 81 by the spiral conveying blade 83, it will smoothly enter the inner side of the delivery ring 1 through the discharge pipe 85 for re-crushing.

[0095] In a preferred embodiment, the present invention can be further configured as follows: Figure 8 , Fig. 9 As shown; one end of the feed hose 84 away from the shell 81 is located above the lowest part of the screening net 72, wherein the unqualified to-be-crushed materials on the screening net 72 can enter the shell 81 through the feed hose 84. In the vertical impact crushing device, the screening net 72 of the screening assembly 7 is responsible for separating the fine particle materials that meet the particle size requirements from the oversized particles or impurities, and the one end of the feed hose 84 away from the shell 81 is precisely positioned above the lowest part of the screening net 72. When the screening process is in progress, the fine particle materials that meet the particle size requirements will pass through the sieve holes of the screening net 72 and fall into the bottom of the containing tube 71, and will be collected and processed through the discharge pipe 73, while the unqualified to-be-crushed materials, i.e., the oversized particles or impurities, will remain on the screening net. 72, and gradually accumulate at the lowest point of the screening net as the screening continues. Since one end of the feed hose 84 is located above the lowest point of the screening net 72, when these substandard materials to be crushed accumulate to a certain extent, they will naturally fall into the feed hose 84. Subsequently, these materials to be crushed will be smoothly transferred to the outer shell 81 through the feed hose 84, and then driven by the spiral conveying blades 83, and transported upward along the inner wall of the outer shell 81. Finally, these substandard materials to be crushed will be transported back to the inner side of the delivery ring 1 through the discharge pipe 85 for another impact crushing process. In this way, through continuous circulation and screening, it can be ensured that all materials can meet the required particle size requirements.

[0096] In a preferred embodiment, the present invention can be further configured as follows: Figure 1 , Fig. 9 As shown; the transmission shaft 82 and the driving column 10 are rotationally connected through the third belt transmission assembly 23, and the third belt transmission assembly 23 is mainly composed of a belt and two pulleys, one of which is fixedly mounted on the driving column 10, and the other pulley is fixedly mounted on the extended end of the transmission shaft 82. When the driving column 10 rotates, it will transmit the rotational power to the transmission shaft 82 through the pulley and the belt to rotate together. As the transmission shaft 82 rotates, the spiral conveying blade 83 fixedly mounted on its outer side will also rotate together. The rotation of the spiral conveying blade 83 will generate an upward thrust, thereby conveying the material forward along the inner wall of the outer shell 81. In this way, the material can enter the outer shell 81 through the feed hose 84, be conveyed to the discharge pipe 85 by the spiral conveying blade 83, and finally be put back to the inner side of the delivery ring 1 for further processing.

[0097] The specific working principle of a vertical impact crushing device of the present invention is as follows:

[0098] First, the second driving motor 11 is started, and the driving column 10 is driven to rotate axially at the center of the cross mounting frame 9 through the first belt transmission assembly 12. The rotation of the driving column 10 stirs the to-be-crushed material located above the spacer ring 3 through the toggle rod 13, so that it falls downward from the central hollow of the spacer ring 3 to the crushing area. At the same time, the rotation of the driving column 10 also drives the driving gear 17 to rotate through the second belt transmission assembly 24 and the transmission rod 16, and then through the meshing action of the gear ring 18, the outer cylinder 5 is rotated and displaced in one direction on the inner side of the first connecting ring 15;

[0099] Next, the first driving motor 43 is started to drive the transmission shaft to rotate, thereby driving the first cam 44 and the second cam 46 fixedly mounted on the outer side of the transmission shaft to rotate synchronously. When the first cam 44 rotates to contact with the first transmission member 45, it pushes the first transmission member 45 to slide on the surface of the frame 42, and the reciprocating vertical displacement of the crushing plate 48 is achieved through the cooperation of the second transmission member 47 and the second cam 46. The reciprocating motion of the crushing plate 48 cooperates with the spacer ring 3 to reciprocate and impact the material to be crushed, and the crushed material falls downward through the first through hole on the surface of the crushing plate 48 onto the rotating impact member 6;

[0100] At the same time, as the driving column 10 rotates, the base 61, the second connecting ring 62, the third connecting ring 64 and other components will move in one direction, and under the meshing action of the driving gear 17 and the gear ring 18, the outer cylinder 5 will rotate in another direction, so that the materials falling on the rotating impact member 6 are crushed by secondary impact through the cooperation of the convex strips 65 and the inner lining plate 66;

[0101] After two impact crushings, the material will fall into the receiving tube 71 of the screening assembly 7, and will be screened by the inclined screening net 72. The fine particles that meet the particle size requirements will pass through the sieve holes of the screening net 72 and fall into the bottom of the receiving tube 71, and will be discharged through the discharge pipe 73, while the unqualified materials to be crushed will remain above the screening net 72.

[0102] At this time, due to the rotation of the outer cylinder 5, through the cooperation of the sliding limit rod 21 and the sliding groove 20, the receiving cylinder 71 is driven to move up and down reciprocatingly, thereby realizing the shaking of the screening component 7 and improving the screening effect. At the same time, the substandard to-be-crushed materials remaining above the screening net 72 will enter the housing 81 of the transmission component 8 through the feeding hose 84;

[0103] Since the transmission shaft 82 and the driving column 10 are rotatably connected via the third belt transmission assembly 23, the rotation of the driving column 10 drives the transmission shaft 82 to rotate, thereby driving the spiral conveying blades 83 to convey the material forward along the inner wall of the housing 81. Finally, the material is conveyed back to the inner side of the delivery ring 1 through the discharge pipe 85 for another impact crushing process.

[0104] During the entire use process, the use of the sealing cover 22 prevents the material to be crushed from being thrown out of the inner side of the delivery ring 1 during the impact crushing process, and can also suppress dust, thereby achieving effective crushing, screening and re-crushing of the material to be crushed, and improving the crushing efficiency and product quality.
