Description

Technical Field

[0001] The invention relates to the technical field of aquaculture, and in particular to a raw material crushing device for producing and processing aquaculture feed. Background Art

[0002] Aquaculture refers to the production activities of breeding, cultivating and harvesting aquatic plants and animals under human control. According to the nutritional needs of different farmed species, feed is scientifically formulated and fed. Reasonable feed feeding can not only ensure the growth of aquatic animals, but also reduce water pollution.

[0003] With the vigorous development of aquaculture, the demand for aquaculture feed continues to rise and the quality requirements are becoming more stringent. As the core input of aquaculture, the quality of feed is directly related to the growth performance, health status and breeding benefits of aquatic animals. In the process of feed production and processing, raw material crushing is an extremely critical link.

[0004] The prior art publication number is CN114887747B, which provides a raw material crushing device for the production and processing of aquaculture feed, including a crushing box and a crushing part located in the crushing box, a mixing box is arranged below the crushing part, and the feed without bran and rice bran reaches the mixing box below through the crushing part, and the bran and rice bran in the shape of translucent small thin sheets entering the lower barrel will be pressed and cut into four parts by a cross blade, which can effectively solve the problem that the bran and rice bran are very soft and difficult to be squeezed and crushed into the required size by the crushing roller; the magnetic field generated by the electromagnetic generator is a changing magnetic field, which has the effect of driving the second half pipe to reciprocate on the first half pipe, so that the crushed bran and rice bran feed discharged from the discharge pipe can be integrated and formed into a sphere, which is convenient for later feeding.

[0005] The above-mentioned prior art uses a cross blade to cut the feed in the shape of small thin slices and then integrate the feed, but the cutter can only cut once and cannot change the angle repeatedly for multiple cuttings. In addition, the cavity is fixed and cannot cooperate to achieve a better cutting effect. The prior art also lacks a structure for crushing the feed in the shape of small thin slices and other harder feeds together.

[0006] It can be seen that a raw material crushing device for the production and processing of aquaculture feed is needed to solve the problems mentioned in the above background technology that the existing technology for cutting small thin slices of feed cannot change the angle of the tool for repeated cutting, the cavity cannot be changed and matched, and it cannot be crushed and crushed together with other feeds.

[0023] 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.

[0024] See also Figure 1-Figure 7A raw material crushing device for aquaculture feed production and processing, comprising a shell 1, the shell 1 comprising a chopping box 101 and a grinding box 103, and a fixed partition 102 is fixedly arranged inside the chopping box 101, an extrusion assembly 3 is arranged inside the shell 1, and the extrusion assembly 3 comprises a first movable partition 301 and a second movable partition 302 movable on one side of the fixed partition 102, a cutter assembly 2 is installed above the shell 1, and the cutter assembly 2 comprises a cutter 201 that can be raised and lowered and rotated between the first movable partition 301 and the second movable partition 302, the top of the cutter 201 is connected to a lifting rod 202, and the lifting rod 202 The rotating barrel 203 is penetrated, and a rotating tooth 2031 and an inclined groove 2032 are arranged on the outer side of the rotating barrel 203, and a toggle rod 2092 and an arc plate 2091 for intermittently toggling the rotating barrel 203 are arranged on one side of the rotating barrel 203. The top of the lifting rod 202 is connected to the lifting block 205, and the lifting block 205 drives the lifting rod 202 to rise and fall along the inner wall of the back plate 204. The first movable partition 301 and the second movable partition 302 are both cross-shaped structures, and the blades of the first movable partition 301 and the second movable partition 302 rotate in contact with the inner wall of the shredder box 101, and the first movable partition 301 and the second movable partition 302 rotate in opposite directions.

[0025] In this embodiment, a controller is installed in the device, which is electrically connected to the electronic components in the device and can directly control the operation of the device. There are various crushing methods in the crushing equipment, including roller crushing, crushing knife crushing, grinding crushing, hammer crushing, extrusion crushing and other methods. For the crushing of small thin flakes in aquaculture raw materials, a blade chopping method can obtain a better crushing effect. For example, raw materials such as shrimp skin, shrimp shell, and bran are thin in texture, small in size, and have a certain toughness. Therefore, the applicable object in the chopping link of this device is small thin flake raw materials, and in the hammer crushing link, it is suitable for small thin flake raw materials and other feeds with relatively hard texture, such as crab shells, grains, stone powder, meat and bone meal and other raw materials.

[0026] Specifically, the number of the fixed partitions 102 is four groups, and the four groups of fixed partitions 102 are equidistantly distributed inside the shredder box 101 , and the four groups of fixed partitions 102 are distributed in a cross structure.

[0027] In this embodiment, although the four groups of fixed partitions 102 are in a cross structure, there is no connection at the middle gathering point, including the first movable partition 301 and the second movable partition 302 installed later, which are only connected at the bottom of the cross structure, and the upper part is cut at an angle. There is no connection part at the gathering point, which is convenient for the descent of the lifting rod 202, and the connection between the cutter 201 and the lifting rod 202 is only a part, so when the lifting rod 202 descends to the cross structure connection between the first movable partition 301 and the second movable partition 302, the cutter 201 has already contacted with the feed at the bottom and completed the cutting, so the four groups of fixed partitions 102 and the rotatable first movable partition 301 and the second movable partition 302 will not affect the descent of the cutter 201, and the chopping box 101 is a cylindrical structure. The division of the fixed partition 102 makes the inside of the chopping box 101 have four groups of spaces with the same capacity. These four groups of spaces are used to place the feed raw materials to be chopped.

[0028] Specifically, a limit block is provided on the outer side of the lifting rod 202, and a limit groove matching the limit block is provided inside the rotating barrel 203. The rotating teeth 2031 are evenly distributed at the upper and lower ends of the rotating barrel 203, and the rotating teeth 2031 include a plurality of teeth, and a gap is provided between each tooth. The inclined groove 2032 includes a plurality of inclined grooves, and longitudinally connects the gaps between the upper and lower sets of teeth.

[0029] In this embodiment, the cutter 201 rotates one circle to form a circle, and all the cutters 201 cut in a manner of dividing the circle into equal parts. In order to avoid contact with the fixed partition 102 during cutting, the inclined groove 2032 is arranged in a manner that a larger tilt occurs every several groups of normal tilts, so that when the toggle rod 2092 toggles the rotating barrel 203 to rotate, there will be a larger rotation at every several rotations at the same angle, thereby skipping the position of the fixed partition 102. If the rotating barrel 203 is not arranged in this manner, the inclined groove 2032 can be arranged in an equidistant manner, and a larger gap can be used to skip the position of the fixed partition 102. The lower cutting position of the cutter 201 needs to make way for the moving positions of the first movable partition 301 and the second movable partition 302.

[0030] Specifically, a back plate 204 is installed on the rear side of the rotating barrel 203, and a movable groove is set on the back plate 204, a lifting block 205 is located inside the movable groove, and one side of the bottom end of the lifting block 205 is connected to the lifting rod 202, an arc groove 206 is connected to the rear side of the lifting block 205, and a through shaft 2071 passes through and moves in the arc groove 206, the through shaft 2071 is set on the rocker 207, and a first pulley group 208 is connected to one side of the rocker 207, a driving motor 210 is installed at the rear of one side of the first pulley group 208, and a rotating block 209 is connected to the front of one side of the first pulley group 208, an arc plate 2091 and a toggle rod 2092 are set on the outside of the rotating block 209, and the arc plate 2091 is in contact with the rotating tooth 2031, and the toggle rod 2092 is in contact with the inclined groove 2032.

[0031] In this embodiment, a connecting disk is provided on the top of the rotating barrel 203, and a bearing is provided inside the connecting disk. The connecting disk is connected to the back plate 204. When the rotating barrel 203 rotates as a whole, the connecting disk is fixed by the back plate 204 so that it does not rotate. A mounting plate is also provided on the rear side of the back plate 204, which is connected to the ground or the outer side of the shell 1 to provide support for the cutter assembly 2. When the driving motor 210 is started to drive the rotating block 209 to rotate, the toggle rod 2092 is responsible for contacting the inclined groove 2032. When rotating, the rotating barrel 203 is toggled along an inclined trajectory to rotate it a certain angle. As the rotating block 209 continues to rotate, the arc plate 2091 will enter the gap between the two sets of rotating teeth 2031, hold it against it, and keep it stopped. When the arc portion of the arc plate 2091 is completely out of contact with the rotating teeth 2031, the rotating barrel 203 will continue to rotate.

[0032] Specifically, a gap is provided at the middle position of the first movable partition 301 and the second movable partition 302, and the first movable partition 301 and the second movable partition 302 overlap through the gap, and the bottom ends of the first movable partition 301 and the second movable partition 302 are provided with arc circles 303, and the outer sides of the arc circles 303 are equidistantly provided with dividing wheels 304, the dividing wheels 304 penetrate the shredder box 101 and extend to the outside thereof, and a dividing worm 305 matching the dividing wheel 304 is provided on one side of the dividing wheel 304.

[0033] In this embodiment, the first movable partition 301 and the second movable partition 302 are both four-piece structures, which are respectively located on both sides of the fixed partition 102. There is a group of sheet structures on both sides of a group of accommodating chambers. The two groups of sheet structures belong to the first movable partition 301 and the second movable partition 302 respectively. The direction of movement is close to each other. The two groups of sheet structures are attached to the fixed partition 102 in the initial state to ensure the maximum placement space, and then gradually approach with the start of the rotating motor 311, which will squeeze the feed inside, so that the feed is fixed on both sides when cutting, and the feed will not move during cutting, ensuring the cutting effect. With the squeezing, the original cutting trajectory will move, so that the position where the cutting knife falls next time will not be in the original position, so that the feed can be cut more finely and the cutting effect can be further enhanced.

[0034] Specifically, one end of the split worm 305 is connected to a gear set 306, and the gear set 306 includes two groups of meshing gears, one side of one group of gears is connected to the second pulley set 307, one side of the second pulley set 307 is provided with a small gear 308, and one side of the small gear 308 is meshed with a large gear 309, one side of the large gear 309 is provided with an articulated arm 310, and the articulated arm 310 includes a large articulated shaft, a middle articulated shaft and a small articulated shaft, the three groups of articulated shafts are articulatedly connected, and a rotating motor 311 is installed on the rear side of the articulated arm 310.

[0035] The cam divider is formed between the dividing wheel 304 and the dividing worm 305. When the dividing worm 305 rotates one circle, it will contact a group of dividing wheels 304, so that the overall position of the arc circle 303 moves according to a certain distance. In this way, the position of each movement of the second movable partition 302 and the first movable partition 301 can be predicted in advance, which is convenient for setting the rotating barrel 203 in advance, so that the cutter 201 will not contact the first movable partition 301 or the second movable partition 302 when cutting. The same structure as the dividing worm 305 is also provided on the rear side of the pinion 308, which cooperates with the dividing wheel 304 under the second movable partition 302, so that when the pinion 308 rotates, it can simultaneously drive the first movable partition 301 and the second movable partition 302 to rotate, and the existence of the gear set 306 makes the two groups of dividing worm 308 rotate. 05 The rotation directions are opposite, so that the overall rotation directions of the first movable partition 301 and the second movable partition 302 are opposite, and the existence of the articulated arm 310 and the large gear 309 can make the small gear 308 reverse quickly. One end of the large articulated shaft of the articulated arm 310 is fixedly connected to the large gear 309, and the output end of the rotating motor 311 is fixedly connected to one end of the small articulated shaft. After starting, it will drive the other end of the small articulated shaft to rotate in a circle. The small articulated shaft drives the large articulated shaft to rotate through the middle articulated shaft, but the large articulated shaft will not rotate a complete circle. The middle articulated shaft will push the large articulated shaft to rotate and then pull back, so that the large gear 309 will reverse after rotating forward, so that the small gear 308 will reverse after rotating forward, which will make the first movable partition 301 and the second movable partition 302 move back after being squeezed, restore the initial state, and make room for the next feeding.

[0036] See also Figure 8 , a raw material crushing device for aquaculture feed production and processing, a feeding assembly 4 is provided at the bottom end of the chopping box 101, and the feeding assembly 4 includes a feeding motor 401, and the output end of the feeding motor 401 is connected to a rotating shaft 402, the rotating shaft 402 passes through the shell 1 and extends to the inside thereof, and one end of the rotating shaft 402 is connected to a rotating blade 403, a connecting plate 404 is provided below the rotating shaft 402, and a connecting rod 405 is connected to the outside of the connecting plate 404, the number of the rotating shaft 402, the rotating blade 403, the connecting plate 404 and the connecting rod 405 are all multiple groups, and the multiple groups of rotating shafts 402 are equidistantly distributed on the outside of the shell 1, the multiple groups of connecting rods 405 are connected end to end through the connecting plate 404 to form a circle, the multiple groups of rotating blades 403 are all triangular structures, and a center block 406 is provided at the converging point of the ends of the multiple groups of rotating blades 403, and the multiple groups of rotating blades 403 all rotate on the outside of the center block 406.

[0037] In this embodiment, there is a central axis at both the front and rear ends of the rotating blade 403. The rotating blade 403 rotates around the central axis. The central axis at the rear end of the rotating blade 403 is set at the contact point between the rotating blade 403 and the center block 406. After starting the unloading motor 401, the unloading motor 401 will drive the rotating shaft 402 to rotate. Through the transmission of the connecting rod 405, multiple groups of rotating shafts 402 will rotate together at the same rotation angle, so that the internal multiple groups of rotating blades 403 will rotate together at the same rotation angle, which makes it convenient for the raw materials after shredding above to pass through the channel and fall into the grinding bowl 518.

[0038] See also Figure 8-Figure 10 A raw material crushing device for the production and processing of aquaculture feed, a grinding box 103 is provided with a grinding assembly 5 inside, the grinding assembly 5 includes a rotating grinding bowl 518, and a liftable hammer block 507 is provided inside the grinding bowl 518, and a flip block 513 that can swing intermittently is provided on one side of the hammer block 507.

[0039] In this embodiment, the grinding motor 501, the third pulley group 502, the rotating block 503, the outer sleeve block 504, the disc gear 508, the first half gear 509, the second half gear 510, and the pin disk 514 are all arranged on the outside of the outer shell 1, the first hinged arm 505, the rotating arm 511, the cage gear 515 and the driving gear 516 all penetrate the outer shell 1 and extend into the interior thereof, and an openable door is provided on the front side of the outer shell 1 for convenient feeding and taking out of materials, and the grinding bowl 518 can be arranged to be detachably connected to the driven gear 517, so that it will be easier to take out and clean the grinding bowl 518, and the device will have a better feel.

[0040] Specifically, the grinding assembly 5 includes a grinding motor 501, and the output end of the grinding motor 501 is connected to the third pulley group 502, a rotating block 503 is arranged on one side of the third pulley group 502, and two groups of extension arms 5031 are symmetrically connected to the outer side of the rotating block 503, an outer sleeve block 504 is sleeved on the middle outer part of the rotating block 503, and the outer part of the outer sleeve block 504 is connected to the extension block 5041, a protrusion 5042 is connected to one side of the extension block 5041, and the protrusion 5042 is in contact with the extension arm 5031, one end of the outer sleeve block 504 is hinged with a first articulated arm 505, and a second articulated arm 506 is hinged below the first articulated arm 505, and the bottom end of the second articulated arm 506 is connected to a hammer block 507.

[0041] In this embodiment, the hammer block 507 is made of metal material and has a certain weight.

The grinding bowl 518 is made of metal and will not be easily damaged under the action of hammering, thereby extending the service life of the device.

[0042] Specifically, a disc gear 508 is connected to the lower part of one side of the third pulley group 502, and teeth 5081 are arranged on the front side of the disc gear 508, and the number of teeth 5081 is two groups. A first half gear 509 and a second half gear 510 are arranged on one side of the disc gear 508, and the first half gear 509 and the second half gear 510 are connected by an axis, and the first half gear 509 and the second half gear 510 are both meshed with the teeth 5081, and a rotating arm 511 is arranged on one side of the second half gear 510, and an extension rod 512 is connected to one side of the rotating arm 511, and a flip block 513 is arranged below the extension rod 512.

[0043] In this embodiment, the flipping block 513 will flip over the raw materials when the hammer block 507 is lifted, and cooperate with the rotating grinding bowl 518, so that the raw materials are flipped over once each time they are hammered, so that the raw materials inside the grinding bowl 518 can be evenly hammered and crushed. The first half gear 509 and the second half gear 510 are arranged relatively to each other. After the first set of teeth 5081 contacts the first half gear 509, the rotating arm 511 rotates forward once, and then the first set of teeth 5081 contacts the second half gear 510, and the rotating arm 511 rotates reversely. The two sets of teeth 5081 are not evenly distributed on the disc gear 508 at equal intervals, so there will be blank parts after the forward and reverse rotations. At this time, the flipping block 513 does not move. At this time, the hammer block 507 is hammering the feed. After waiting for the hammering to end, the flipping block 513 will flip the feed to facilitate the next hammering. There is a time difference between the movement of the flipping block 513 and the hammer block 507, and they will not move together.

[0044] Specifically, a pin disk 514 is provided below the third pulley group 502, and a cage gear 515 is meshed on one side of the pin disk 514, a driving gear 516 is connected to the bottom end of the cage gear 515, and a driven gear 517 is meshed on one side of the driving gear 516, a grinding bowl 518 is provided above the driven gear 517, and the hammer block 507 and the flip block 513 are both located inside the grinding bowl 518.

[0045] In this embodiment, the third pulley group 502 includes a pulley located on one side of the grinding motor 501, a multi-groove pulley located on one side of the disc gear 508 and a belt wrapped around their outside, and a group of belts are connected to the pin disk 514 below the multi-groove pulley. When the pin disk 514 rotates, the pin on one side will continuously move the internal column of the cage gear 515, thereby allowing the cage gear 515 to rotate. The cage gear 515 drives the driving gear 516 to rotate, and then drives the meshing driven gear 517 to rotate, so that the grinding bowl 518 rotates together. The rotation allows the feed inside to be evenly hammered by the hammer block 507, thereby obtaining a better crushing effect.

[0046] When in use, it is necessary to connect to an external power supply, which provides electrical energy for the device so that the device can operate normally. First, the feed raw materials are placed in equal parts inside the chopping box 101, and the fixed partition 102 divides the feed to form four equal-space accommodating chambers inside the chopping box 101. The drive motor 210 is started, and the drive motor 210 drives the rotating block 209 and the rocker 207 to rotate at the same time through the arc groove 206. When the rocker 207 rotates, it drives the arc groove 206 and the lifting block 205 to rise and fall through the through shaft 2071, thereby driving the lifting rod 202 to rise and fall. When the rotating block 209 rotates, it contacts the inclined groove 2032 through the toggle rod 2092, and the rotating barrel 203 is rotated as a whole according to the inclined trajectory. Then the arc plate 2091 will rotate to the gap between the rotating teeth 2031 to play a stopping role. The combination of the two movements will cause the lifting rod 202 to drive the cutter 201 descends to cut the raw material, then rises and rotates a certain angle, and then descends again to cut the raw material repeatedly. When the cutter 201 is lifted, the started rotating motor 311 will drive the large gear 309 to rotate through the articulated arm 310. The large gear 309 drives the small gear 308 to rotate through the meshing relationship. The small gear 308 drives the dividing worm on the rear side to rotate, which will drive the dividing wheel under the second movable partition 302 that cooperates with the dividing worm to move. The small gear 308 will also drive the gear set 306 to rotate through the second pulley set 307, thereby driving the dividing worm 305 to rotate in the opposite direction, so that the first movable partition 301 and the second movable partition 302 rotate in the opposite direction, thereby reducing the accommodating cavity for placing the raw material, and using the first movable partition 301 and the second movable partition 302 to squeeze the raw material in the accommodating cavity for cutting. After the cutting and crushing is completed, the unloading motor 401 is turned on to rotate the rotating shaft 402. The connecting plate 404 and the connecting rod 405 drive all the rotating shafts 402 around the outer side of the housing 1 to rotate synchronously. The rotation of the rotating shaft 402 drives the rotating blades 403 to flip, thereby opening the unloading channel, so that the raw materials in the shredder box 101 enter the interior of the grinding bowl 518 through the unloading assembly 4. The grinding motor 501 is started, so that the grinding motor 501 drives the third pulley set 502 and the rotating block 503 to rotate. When the rotating block 503 rotates, the extension arm 5031 passes through the protruding convex block 5042, thereby driving the outer cover block 504 to rotate as a whole. The outer cover block 504 rotates and drives the hammer block 507 to rise and fall once through the first hinged arm 505 and the second hinged arm 506. Because the hammer block 507 forms a hammer due to its own weight, the rotating third pulley set 502 drives the disc gear 508 to rotate, and the two sets of teeth 5081 are respectively connected with the first half gear 509 and the second half gear When the wheel 510 is engaged, it will rotate forward and reverse once. The rotation is transmitted to the turning block 513 through the rotating arm 511 and the turning block 513, so that the turning block 513 is turned back and forth to turn the feed once, and the third pulley group 502 also drives the pin disk 514 to rotate at the same time, and the pin disk 514 drives the cage gear 515 to rotate, thereby rotating the driving gear 516, and the driving gear 516 drives the driven gear 517 engaged with it to rotate, and then drives the grinding bowl 518 to rotate, so that the raw material is hammered while rotating, and the material is turned over while being hammered and crushed, thereby enhancing the effect of hammering and crushing.
