[0047] The shell crushing equipment is suitable for aquaculture, food processing, fishery and the like, and can efficiently crush hard waste such as shells, so as to facilitate subsequent processing or resource utilization.

[0048] The shell crushing equipment comprises a machine shell 100 and a crushing module for crushing the shells.

[0049] The crushing module comprises a driving unit 200, a transmission shaft 230 and a crushing assembly connected with the transmission shaft 230.

[0050] In some embodiments of the present application, the shell crushing equipment comprises a base body 900 for supporting and bearing the entire equipment.

[0051] When arranged, the machine shell 100 is fixedly assembled above the base body 900, the driving unit 200 is arranged on the base body 900 at one side of the machine shell 100, and the crushing assembly and the transmission shaft 230 are arranged inside the machine shell 100.

[0052] In some embodiments of the present application, a crushing cavity 110 is formed in the machine shell 100, a connecting shaft 400 and a crushing assembly are arranged inside the crushing cavity 110, and the crushing cavity 110 is mainly used for accommodating the shells to be crushed in the crushing module.

[0053] A feeding portion 120 is arranged at the upper portion of the machine shell 100 and communicates with the crushing cavity 110, and is used for introducing the shell material into the crushing cavity 110. The feeding portion 120 is a feeding port and is formed at the top position of the machine shell 100.

[0054] A discharging portion 130 is formed on the machine shell 100 and is used for discharging the crushed shell material from the crushing cavity 110.

[0055] The discharging portion 130 is a discharging port and is formed at the bottom position of the machine shell 100, and is used for discharging the crushed shell material from the crushing cavity 110.

[0056] When crushing, the shells are introduced from the feeding portion 120, then enter the crushing cavity 110 and are crushed by the crushing assembly, and the crushed material enters the discharging portion 130 and is discharged.

[0057] In some embodiments of the present application, the crushing module comprises a driving unit 200, a transmission shaft 230 connected with the driving unit 200 and a crushing assembly assembled on the transmission shaft 230.

[0058] The driving unit 200 comprises a driving motor 210 and a transmission device 220, and the transmission device 220 is a belt wheel transmission device 220 or a chain wheel transmission device 220.

[0059] The driving device is assembled on the base body, and rotation of the driving device transmits power to the transmission device 220, which transmits power to the transmission shaft 230 connected thereto, to drive the transmission shaft 230 to rotate.

[0060] The crushing assembly is assembled on the transmission shaft 230 and is used for crushing shells. When the transmission shaft 230 is driven to rotate by the driving device, the crushing assembly assembled thereon is driven to operate to crush the shells.

[0061] In some embodiments of the present application, the crushing assembly comprises:

[0062] The plurality of hammer body units 300 are arranged along the axial direction of the transmission shaft 230, and each hammer body unit 300 comprises a plurality of hammer pieces 310 arranged along the circumferential direction of the transmission shaft 230, and the hammer pieces 310 are perpendicularly connected to the connecting shaft 400.

[0063] The plurality of hammer body units 300 arranged along the axial direction of the transmission shaft 230 can ensure that the hammer body units 300 can be in large-area contact with the shells entering the crushing cavity 110, so as to ensure the crushing efficiency of the shells.

[0064] The plurality of hammer pieces 310 on the plurality of hammer body units 300 form a plurality of columns along the axial direction of the connecting shaft 400, and the space between any two adjacent columns of hammer pieces 310 in the axial direction can fall into the shells. During rotation of the connecting shaft 400, the plurality of hammer pieces 310 in each column are simultaneously driven to rotate and apply impact force to the shells, so as to achieve the large-area crushing effect of the shells.

[0065] In some embodiments of the present application, each hammer piece 310 is formed with a hammer crushing surface, and a hammer tip portion 311 is formed on the hammer crushing surface, which is used for crushing the shells.

[0066] The hammer tip portion 311 is narrow and sharp, so that a large pressure can be concentrated and applied during crushing, and hard materials such as shells can be effectively penetrated and crushed.

[0067] The structure of the hammer tip portion 311 can also reduce the sliding phenomenon of the shells during crushing, so as to achieve full and sufficient crushing of the shells, avoid the problem of back-and-forth crushing caused by slipping of the shells, and improve the crushing efficiency.

[0068] In some embodiments of the present application, the hammer piece 310 is a cuboid hammer block, which can apply a large hammering force to the shells.

[0069] In some embodiments of the present application, the crushing assembly comprises a connecting unit for connecting a plurality of hammer body units 300 along the axial direction of the transmission shaft 230, comprising a plurality of connecting shafts 400, each of which passes through a plurality of hammer body units 300 arranged in multiple columns of hammer body pieces 310 along the axial direction of the transmission shaft 230.

[0070] After a plurality of hammer body units 300 are arranged in sequence along the connecting shaft 400, the hammer body pieces 310 above them form multiple columns of hammer body pieces 310 arranged axially along the connecting shaft 400.

[0071] The connecting shaft 400 is provided in the same number as the number of columns of hammer body pieces 310, and is used to be inserted between the multiple columns of hammer body pieces 310.

[0072] During connection, a connecting hole 313 is provided on each hammer body piece 310, and the connecting shaft 400 passes through the multiple connecting holes 313 in sequence along the axial direction of the transmission shaft 230.

[0073] The hammer blade 500 is rotationally arranged at the connecting shaft 400 between any two axially adjacent hammer body pieces 310.

[0074] The hammer blade 500 is rotationally connected to the connecting shaft 400, the connecting shaft 400 is connected to the hammer body piece 310, and the connecting shaft 400 is rotated when the hammer body piece 310 rotates. Under the action of inertial force, the hammer blade 500 rotationally connected to the connecting shaft 400 is spun outward at high speed by rotating relative to the connecting shaft 400, and the high-speed spun hammer blade 500 can exert a high-speed instantaneous impact force on the shell to crush the sharp shell, achieving the best crushing effect of the sharp shell.

[0075] In addition, when the hammer blade 500 contacts the shell, the shell will generate a certain reverse impact force on the hammer blade 500. Since the hammer blade 500 can rotate circumferentially along the connecting shaft 400, when subjected to the reverse impact force of the shell, the hammer blade 500 can adjust its position in the circumferential direction by rotating relative to the connecting shaft 400, thereby reducing the resistance to the connecting shaft 400 and energy loss during the crushing process, and prolonging the service life of the equipment.

[0076] In some embodiments of the present application, the hammer blade 500 is a long and thin piece, and a connecting portion 520 is provided thereon, which is a through hole and is arranged on the connecting shaft 400 through the through hole.

[0077] In order to realize the relative rotation between the hammer blade 500 and the connecting shaft 400, a gap is provided between the through hole and the connecting shaft 400 to realize a certain amount of movement between them, so that the hammer blade 500 can be spun out at high speed when the hammer body piece 310 rotates.

[0078] In order to enhance the crushing effect, a plurality of hammers 500 are arranged on the connecting shaft 400 between two adjacent hammer body parts 310 in the axial direction. In order to ensure that the plurality of hammers 500 do not adhere to each other, a spacing protrusion can be arranged on the connecting shaft 400 to limit the axial movement position of the hammers 500 along the connecting shaft 400, so that the hammers 500 can only rotate along the circumferential direction.

[0079] In some embodiments of the present application, the hammers 500 are formed with a hammer crushing surface, and the hammer crushing surface is formed with a hammer tip portion 510.

[0080] The hammer tip portion 510 is narrow and sharp, so as to concentrate a larger pressure during crushing, effectively penetrating and crushing hard substances such as shells.

[0081] The structure of the hammer tip portion 510 can also reduce the sliding phenomenon of the shells during crushing, so as to achieve full and sufficient crushing of the shells, avoid the problem of back and forth crushing caused by shell slipping, and improve the crushing efficiency.

[0082] The shell crushing equipment improves the structure of the crushing assembly. The crushing assembly adopts the structure of the hammer body part 310 and the hammer 500. During use, the heavy hammer body part 310 provides stable and continuous impact and crushing to the shells, achieving coarse crushing of the shells.

[0083] The thin and sheet-shaped hammer 500 structure connected between adjacent hammer body parts 310 is driven to rotate by the inertia force, so as to apply a high-speed impact force to the shells, achieving fine crushing of the shells.

[0084] Through the combination of coarse crushing and fine crushing, the shells are completely and thoroughly crushed, and the crushing efficiency of the shells is improved.

[0085] During crushing, the hammer body part 310 for coarse crushing and the hammer 500 for fine crushing are in contact with the shells to crush the shells, increase the contact area of the crushing assembly with the shells and the number of components for crushing the shells, and further improve the crushing efficiency of the shells.

[0086] The structure of the hammer body part 310 and the hammer 500 also reduces energy consumption, prolongs the service life, has strong adaptability, and can crush various types of shells.

[0087] In some embodiments of the present application, the hammer unit 300 includes a unit seat 320 assembled to the transmission shaft 230, and the hammer body part 310 is detachably connected to the unit seat 320.

[0088] The unit seat 320 is an annular seat body which is sleeved on the transmission shaft 230 and fixedly connected with the transmission shaft 230.

[0089] The unit seat 320 is arranged to be fixed on the transmission shaft 230, and the hammer body part 310 is arranged to be detachably connected on the unit seat 320. In use, the hammer body part 310 can be replaced according to different types of broken shells.

[0090] For harder shells, the hammer body part 310 with more sharp tooth structures can be replaced to improve the crushing force, and for brittle shells, the hammer body part 310 with a wider tooth spacing can be used to increase the crushing range. By replacing the hammer body part 310, the device can be compatible with processing multiple different types of shells, improving the adaptability and service life of the crushing device.

[0091] In some embodiments of the present application, the transmission shaft 230 is formed with:

[0092] A circumferential limiting portion cooperates with a circumferential mounting portion on the unit seat 320 to limit the circumferential position of the unit seat 320.

[0093] The circumferential limiting portion is a key groove or a key protrusion, and the circumferential cooperating portion on the unit seat 320 is a key protrusion or a key groove matched therewith. The key groove and the key protrusion are inserted and positioned to limit the circumferential rotation of the unit seat 320.

[0094] The axial limiting portions 231 are arranged along the axial direction of the transmission shaft 230, and the adjacent axial limiting portions 231 form an assembly space for accommodating the unit seat 320.

[0095] The axial limiting portion 231 is an axial limiting protrusion protruding from the axial direction, and the unit seat 320 is assembled in the assembly space between two adjacent axial limiting portions 231. The axial limiting portions 231 axially limit the unit seat 320 to ensure the assembly firmness of the unit seat 320.

[0096] In some embodiments of the present application, an insertion slot 321 is formed on the unit seat 320, and a threaded locking hole is formed on the wall of the insertion slot 321.

[0097] An insertion protrusion 312 is formed on the hammer body part 310, and a through hole is formed on the insertion protrusion 312.

[0098] During assembly, the hammer body part 310 is inserted into the insertion slot 321 through the insertion protrusion 312, and then locked and fixed in the threaded locking hole through the through hole by a locking screw, to realize the detachable connection between the hammer body part 310 and the unit seat 320.

[0099] In some embodiments of the present application, the hammer body crushing surface is formed on at least the surface of the hammer body part 310 facing the shell. Forming the hammer body crushing surface on the surface facing the shell ensures full contact with the shell and guarantees the crushing effect on the shell.

[0100] In some embodiments of the present application, the hammer body part includes a hammer body shell-facing surface and other side surfaces, and the hammer body tip part 311 is arranged on the hammer body shell-facing surface and the other side surfaces.

[0101] By arranging the hammer body tip part 311 on the multiple side surfaces of the hammer body part, the number of hammer body tip parts 311 for crushing is increased as much as possible, so that some shells thrown out can also be crushed, improving the crushing efficiency.

[0102] The hammer blade crushing surface is formed on at least the surface of the hammer blade 500 facing the shell. Arranging the hammer blade 500 on the surface facing the shell ensures full contact with the shell and guarantees the crushing effect on the shell.

[0103] In some embodiments of the present application, the hammer blade part includes a blade shell-facing surface and other side surfaces, and the hammer blade tip part 510 is arranged on the blade shell-facing surface and the other side surfaces.

[0104] The hammer blade crushing surface is formed on at least the surface of the hammer blade 500 facing the shell. Arranging the hammer blade 500 on the surface facing the shell ensures full contact with the shell and guarantees the crushing effect on the shell.

[0105] In some embodiments of the present application, the hammer body tip part 311 is a hammer body sharp tooth, and multiple hammer body sharp teeth are arranged to cover the hammer body crushing surface.

[0106] In some embodiments of the present application, the hammer body sharp tooth is a sharp trapezoidal protrusion, and multiple sharp trapezoidal protrusions are arranged to form grooves between the multiple sharp trapezoidal protrusions.

[0107] The sharp trapezoidal protrusion can reduce the contact surface, ensure that concentrated force can be applied to the shell, and improve the crushing efficiency. The inverted trapezoidal grooves between the teeth facilitate the occlusion of the shell during the crushing process, enhance the gripping force, reduce the sliding of the shell during the crushing process, avoid uneven crushing caused by sliding, and thereby improve the crushing efficiency.

[0108] The hammer blade tip part 510 is a hammer blade sharp tooth, and multiple hammer blade sharp teeth are arranged to cover the hammer blade crushing surface.

[0109] The hammer blade sharp tooth is a sharp trapezoidal protrusion, and multiple sharp trapezoidal protrusions are arranged to form grooves between the multiple sharp trapezoidal protrusions.

[0110] The sharp trapezoidal protrusions can reduce the contact area, ensuring that concentrated force can be applied to the shell, thereby improving the crushing efficiency. The inverted trapezoidal grooves between the teeth facilitate the engagement of the shell during the crushing process, enhancing the gripping force, reducing the sliding of the shell during the crushing process, and avoiding uneven crushing caused by sliding, thereby improving the crushing efficiency.

[0111] In some embodiments of the present application, the hammer piece 500 is provided with a connecting portion 520 connected to the connecting shaft 400. The maximum outer contour of the hammer piece 500 gradually increases in diameter or thickness in a direction away from the connecting portion 520.

[0112] The maximum contour of the hammer piece 500 is arranged to gradually increase in a direction away from the connecting portion 520, which can increase the inertia of the entire hammer piece 500, so that it can be flung out at a higher speed, thereby improving the crushing effect on the shell.

[0113] Increasing the thickness of the hammer piece 500 in a direction away from the connecting portion 520 can also increase the weight of the hammer piece 500 away from the connecting portion 520, thereby increasing the inertia of the hammer piece 500, so that it can be flung out at a higher speed, thereby improving the crushing effect on the shell.

[0114] In some embodiments of the present application, the inner wall of the shell 100 is provided with a crushing tooth portion 140, which is arranged opposite to the hammer body crushing surface and used to receive the shell flung out from the hammer body crushing surface and crush it.

[0115] The crushing tooth portion 140 is a crushing protruding tooth formed on the inner wall of the shell 100.

[0116] In order to enhance the crushing effect, the inner wall of the shell 100 of the crushing cavity 110 is designed with a crushing protruding tooth. When the shell fragments are hit by the hammer body 310, small pieces of shell that have not been completely crushed will hit the crushing tooth portion 140 of the shell 100 arranged opposite to the hammer body crushing surface, and the shell will be crushed again by the crushing tooth portion 140. This design not only improves the completeness of shell crushing, but also ensures that the output particles are more uniform, reduces the generation of oversized fragments, and meets the application requirements of different particle sizes.

[0117] The crushing protruding tooth can be fixed or detachably connected to the inner wall of the shell 100, so as to be adjusted or replaced according to different crushing requirements. The position and number of the crushing protruding tooth are optimized according to the size and structure of the shell 100, so as to maximize the crushing efficiency.

[0118] In some embodiments of the present application, in order to realize the filtering of the crushed shell, the shell crushing device further comprises a filtering component 600, which is arranged on the shell 100 and located below the crushing assembly.

[0119] The filter component 600 is a screen, which can be used to filter and screen the crushed shell material.

[0120] The screen is a replaceable structure, so that the size of the discharged particles can be adjusted as needed.

[0121] The filter component 600 can be pulled out and assembled on the shell 100, and can also be conveniently and quickly disassembled and replaced when the filter component 600 needs to be disassembled and replaced.

[0122] In some embodiments of the present application, an insertion port 150 is provided on the shell 100, and a pull-out rail 160 corresponding to the position of the insertion port 150 is provided, and the filter component 600 is slidably connected to the pull-out rail 160 through the insertion port 150.

[0123] The pull-out rail 160 is an arc-shaped rail, which can make the screen arranged in a funnel shape when slidably mounted thereon, so as to facilitate the collection of the crushed shell material.

[0124] The pull-out rail 160 is used to cooperate with the screen to facilitate the disassembly and replacement of the screen.

[0125] During assembly, the filter component 600 is slidably mounted to the inside of the shell 100 through the insertion port 150 along the pull-out rail.

[0126] A limiting stopper 700 is provided at the insertion port 150 and is rotatably connected to the machine body, and has a locking position and an unlocking position;

[0127] When in the locking position, it is rotated to block the position of the insertion port 150 to limit the filter component 600;

[0128] When in the unlocking position, it is rotated to the position away from the insertion port 150 to limit the filter component 600.

[0129] The limiting stopper is a limiting stopper handle, which is rotatably connected to the shell 100 and located around the insertion port 150.

[0130] It can change position by rotating relative to the shell 100, and when the filter component 600 is inserted into the shell 100, it can be rotated to the locking position to limit the filter component 600 at the insertion port 150, preventing it from being pulled out.

[0131] When the filter component 600 needs to be disassembled or replaced, the limiting stopper 700 can be rotated to change its position to the unlocking position, and then the filter component 600 can be pulled out of the shell 100.

[0132] In some embodiments of the present application, a cleaning spray system is included, which can clean at least the crushing assembly, the filtering component 600 and the machine shell 100 inside the crushing cavity 110.

[0133] The cleaning spray system includes a spray pipe and a spray head 800, which can be arranged on the machine shell 100 and faces the crushing cavity 110. In use, the tail of the spray pipe can be directly connected with a water pipe to guide water to the spray head 800 to clean the inside of the crushing cavity 110, which can clean the inside of the equipment during or after operation.

[0134] In some embodiments of the present application, a high-pressure water pump is arranged on the spray pipe. The high-pressure water flow can not only remove the attached fragments, but also effectively prevent the accumulation of fine dust, thereby greatly reducing the cleaning and maintenance cost of the equipment.

[0135] The above embodiments are only used to illustrate the technical solutions of the present application, but not to limit it. Although the present application has been described in detail with reference to the foregoing embodiments, the technical solutions recorded in the foregoing embodiments can still be modified by those of ordinary skill in the art, or some technical features can be replaced by equivalents. The modification or replacement does not make the corresponding technical solution deviate from the spirit and scope of the technical solutions claimed by the present application.
