Description

Technical Field

[0001] The invention relates to the technical field of shrimp processing equipment, in particular to an automatic shrimp feeding device. Background Art

[0002] During the automated processing of shrimps, in order to ensure the integrity of the shrimps and the intervals of processing, the precise processing method requires that the shrimps be fed evenly and spaced one by one.

[0003] The fine processing of shrimps has very high requirements on processing equipment, especially the feeding device, which needs to ensure uniform feeding and high efficiency, as well as subsequent cleaning. However, most of the existing shrimp feeding devices use conveyor belts for transmission, and baffles are added to the conveyor belts to realize the transmission of shrimps. Although this can increase the transmission volume of shrimps at one time, it cannot meet the requirements of fine processing for transmission one by one, and the shrimps are easily squeezed and damaged; they are also easy to fall off the baffles in subsequent links, such as when flushed with water, the shrimp bodies are easily washed away by the impact of water. For example, Chinese patent CN201720202389.7 specifically discloses a raw shrimp cleaning and conveying device, in which a conveyor belt, a cleaning tank, a sieve wheel and a discharge end are sequentially arranged in the conveying direction; the conveyor belt conveys raw shrimp obliquely upward; a spray pipe is arranged at the end of the conveyor belt, and the spray pipe sprays water to the conveyor belt to rinse the raw shrimp on the conveyor belt; the end of the conveyor belt is located above the cleaning tank, and a water outlet pipe is arranged in the cleaning tank, and the water outlet pipe supplies water to the cleaning tank so that the water in the tank flows to rinse the raw shrimp, and an overflow port is arranged on one side of the cleaning tank, and the overflow port is located above the sieve wheel; a baffle is arranged on the conveyor belt, and the baffle is perpendicular to the conveying surface of the conveyor belt. It can be seen that it uses a conveyor belt to convey shrimp, but it cannot meet the transmission of each one, and it is easy to cause damage to the shrimp body; and it is easy to fall off under the flushing of water.

[0030] See also Figures 1 to 3The preferred embodiment of the present invention provides an automatic shrimp feeding device, comprising a conveying device 1 and a discharging device 2; the conveying device 1 comprises a housing 101, two conveying rotating shafts 102, two conveying gears 103, a conveying chain 104, a plurality of hooks 105 and a conveying motor (not shown); a first conveying slit 106 is provided on the top plate of the housing 101; the two conveying rotating shafts 102 are respectively installed in the housing 101 through bearings 108, and the two conveying rotating shafts 102 are correspondingly arranged; the two conveying gears 103 are respectively installed on the two conveying rotating shafts 102; the distance between the two conveying gears 103 is less than the distance between the conveying slits length; the transmission chain 104 is meshed and connected with the two transmission gears 103 respectively; a plurality of hooks 105 are respectively installed on the transmission chain 104, and the hooks 105 and the first transmission slit 106 are located on the same vertical plane, and the thickness of the hooks 105 is smaller than the width of the first transmission slit 106; the transmission motor (not shown) is installed outside the shell 101, and the transmission motor (not shown) is connected to any one of the transmission shafts 102; the discharge device 2 is installed on the top plate of the shell 101; and a second transmission slit 204 corresponding to the first transmission slit 106 is opened on the discharge device 2.

[0031] Based on the above scheme, the working principle of the conveying device 1 of the preferred embodiment of the present invention is as follows: the shrimp material is poured into the discharging device 2, and the shrimp material falls on the top plate of the shell 101, and the conveying motor (not shown) is started, and the conveying motor (not shown) drives the conveying shaft 102 to rotate, and the conveying shaft 102 drives one of the conveying gears 103 to rotate. Because the conveying gear 103 is engaged with the conveying chain 104, the conveying chain 104 starts to move, driving the other conveying gear 103 to rotate; and the hook 105 is installed on the conveying chain 104, following the conveying The conveying chain 104 moves, and when the hook 105 moves to one end of the top plate of the shell 101, the hook 105 extends out of the first conveying slit 106, and enters into the discharging device 2 from the second conveying slit 204, hooks and pricks the shrimps in the discharging device 2, and conveys the shrimps one by one to the other end of the top plate of the shell 101, and then as the conveying chain 104 turns, the hook 105 gradually retracts into the shell 101, because the shrimp body cannot enter into the first conveying slit 106 and due to the shrimp body's own gravity, the shrimp body is separated from the hook 105, and the shrimps are evenly fed one by one.

[0032] See also Figure 5 As a preferred solution, the discharge device 2 comprises:

[0033] A first side plate 201, the bottom of which is mounted on the top plate of the housing 101; the bottom edge of the first side plate 201 is parallel to the first transmission slit 106, and the first side plate 201 is inclined in a direction away from the first transmission slit 106;

[0034] A second side plate 202, the bottom of which is mounted on the top plate of the housing 101, and is mirror-symmetrical with the first side plate 201 relative to the first transmission seam 106;

[0035] The third side plate 203, the two sides of the third side plate 203 are respectively connected to the first side plate 201 and the second side plate 202, the bottom of the third side plate 203 is installed on the top plate of the shell 101, and the second conveying seam 204 is opened at the bottom of the third side plate 203; the third side plate 203 is inclined in the direction of shrimp conveying.

[0036] Specifically, the first side plate 201, the second side plate 202 and the third side plate 203 are arranged, and are combined with the top plate of the housing 101 to form a structure with a gradually decreasing width from top to bottom, that is, the self-weight of the shrimps can be dispersed to the inclined first side plate 201 and the second side plate 202, so as to avoid that the weight of the upper layer of shrimps is all applied to the lower layer of shrimps, and avoid that the shrimps are squeezed and damaged, and it can also ensure that the top plate of the housing 101 is always in contact with only one layer of shrimps, thereby reducing the transmission resistance of the shrimps, avoiding that the shrimps that are hooked and barbed are damaged by the backlog on both sides during transportation, and ensuring the integrity of the shrimps. In addition, a large number of shrimps can be put in at one time, and each time a shrimp is transported away, the upper layer of shrimps will slide and fill through the first side plate 201 or the second side plate 202, without the need to put in a single piece or a single layer, which greatly improves the efficiency of transmission and reduces the cost of feeding.

[0037] As a preferred solution, the housing 101 is an oblong structure; both ends of the first conveying slit 106 extend to the arc plate of the housing 101; and the two conveying shafts 102 are respectively arranged at both ends of the housing 101. Specifically, the oblong structure facilitates the shrimp body to slide along the arc plate of the housing 101 when it is separated from the hook 105, ensuring that the shrimp body accurately falls on the equipment of the next process, and also preventing the shrimp body from piling up on the housing 101 and blocking the conveying device 1 from conveying.

[0038] It should be noted that the oblong structure, that is, the left and right ends of the shell 101 are provided with semicircular arc plates, and the oblong structure is common knowledge.

[0039] As a preferred solution, the minimum distance from the conveyor chain 104 to the top plate of the housing 101 is less than the length of the hook 105; on the same side, the minimum distance from the conveyor chain 104 to the arc plate portion of the housing 101 is greater than the length of the hook 105. Specifically, such an arrangement can ensure that the shrimp body is separated from the hook 105 at the arc plate and can slide along the arc plate.

[0040] As a preferred solution, the first transmission slit 106 is parallel to the long axis of the housing 101, and its two ends are connected after extending to the bottom plate of the housing 101 along the long axis direction. Specifically, extending the transmission slit can conveniently adapt to the change of the length of the hook 105 without replacing the housing 101, thereby reducing costs.

[0041] As a preferred solution, a limiting guide rail 107 is further included, and the limiting guide rail 107 is installed on the inner wall of the housing 101; the limiting guide rail 107 is provided with a limiting groove parallel to the first transmission slit 106, and the transmission chain 104 passes through the limiting groove. Specifically, the limiting guide rail 107 can stabilize the transmission chain 104, and prevent the transmission chain 104 between the two transmission gears 103 from being too long and unstable and shaking, which affects the transmission of the shrimp.

[0042] As a preferred solution, the hook 105 is tilted upward along the direction of its movement, and the angle between the hook 105 and the top plate of the housing 101 is 45-65 degrees. Specifically, the upwardly tilted hook 105 can form a certain angle with the shrimp body when hooking the shrimp, making it easier to penetrate into the shrimp body and ensuring that the shrimp body is more stable during the transfer process. When the shrimp is separated from the hook 105, it can also more easily use its own gravity to separate from the hook 105.

[0043] As a preferred solution, a plurality of hooks 105 are evenly arranged on the conveying chain 104. Specifically, the even arrangement of the hooks 105 ensures the orderliness and reliability of the conveying, and also improves the controllability of the conveying.

[0044] As a preferred solution, the length of the conveying chain 104 between two adjacent hook needles 105 is 15 cm.

[0045] See also Figure 4 As a preferred solution, the hook 105 is integrally formed, including a buckle portion 1051 and a needle head 1052, and the buckle portion 1051 is buckled on the conveying chain 104. Specifically, the hook 105 is configured as an integrally formed structure and can be buckled on the conveying chain 104, which is convenient for subsequent maintenance and replacement of the hook 105.

[0046] As a preferred solution, the needle head 1052 is a conical structure, and the angle between the needle head 1052 and the buckle portion 1051 is 45-65 degrees. Specifically, the needle head 1052 is set to a conical structure, which is convenient for the hook needle 105 to hook the prawn.

[0047] The use process of the present invention is as follows: the shrimp material is poured into the feeding device 2, the shrimp material falls on the top plate of the housing 101, the transmission motor (not shown) is started, the transmission motor (not shown) drives the transmission shaft 102 to rotate, the transmission shaft 102 drives one of the transmission gears 103 to rotate, because the transmission gear 103 is meshed with the transmission chain 104, the transmission chain 104 starts to move, driving the other transmission gear 103 to rotate; and the hook 105 is installed on the transmission chain 104, and moves with the transmission chain 104 When the hook 105 moves to one end of the top plate of the shell 101, the hook 105 extends out of the first conveying slit 106 and enters the discharge device 2 from the second conveying slit 204, hooks the shrimps in the discharge device 2, and transports the shrimps one by one to the other end of the top plate of the shell 101. Then, as the conveying chain 104 turns, the hook 105 is gradually retracted into the shell 101. Because the shrimp body cannot enter the first conveying slit 106 and due to the shrimp body's own gravity, the shrimp body is separated from the hook 105, and the shrimps are evenly fed one by one.

[0048] In summary, the preferred embodiment of the present invention provides an automatic feeding device for shrimps. Compared with the prior art, the automatic feeding device for shrimps of the present invention is provided with a hook 105, and the hook 105 is used to fix the shrimps, which satisfies the requirement of feeding the shrimps one by one at uniform intervals, and can also avoid squeezing the shrimps during the transmission process, thereby destroying the integrity of the shrimp bodies. At the same time, the transmission chain 104 is used to drive multiple hooks 105, so that the shrimps can be continuously transported in a cycle, with high transmission efficiency and reliability, low cost, and the hook 105 is also easy to maintain and replace. The entire transmission structure is simple and compact. When cleaning and maintenance are required, only the shell 101 needs to be disassembled for cleaning, which is convenient and quick. In addition, a discharge device 2 is provided, and it is directly mounted on the top plate of the shell 101. The shrimp bodies fall directly on the top plate of the shell 101 to avoid damage to the shrimp bodies due to the height difference.

[0049] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
