Description

Technical Field

[0001] The invention relates to the technical field of shrimp processing equipment, in particular to a shrimp positioning and conveying 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 conveying device, which needs to ensure uniform loading of materials without accumulation or backlog. In addition, the shrimp bodies need to maintain a certain posture during some processing links to facilitate subsequent processing. However, the existing equipment only roughly positions and conveys the shrimp bodies through baffles or support plates. The shrimp bodies are easily deformed and dislocated during the transmission process, and the shrimp bodies cannot be positioned and output, which is not conducive to the subsequent processing steps. 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 the above patent realizes the positioning and conveying of shrimp bodies by arranging a baffle on the conveyor belt, but it cannot guarantee that the shrimp will not be deformed during the transportation process, and the shrimp body is easily deformed and falls off under the spray of water; it is impossible to straighten the shrimp body and position the output shrimp body during the transportation process.

[0027] See also Figures 1 to 3The preferred embodiment of the present invention provides a positioning and conveying shrimp stall device, comprising a conveying device and a rotating device, wherein the conveying device comprises a shell 1, a feeding chute 2, two conveying shafts 3, two conveying gears 4, a conveying motor (not shown), a conveying chain 5 and a plurality of supporting plates 6; the shell 1 is a hollow structure, and passage holes 101 are respectively opened on the two side plates of the shell 1; the feeding chute 2 is arranged on the top surface of the shell 1, and the feeding chute 2 is aligned and connected with the passage holes 101; the two conveying shafts 3 are respectively installed in the shell 1 through bearings 7, and the two conveying shafts 3 are correspondingly arranged at the two ends of the shell 1; the two conveying gears 4 are respectively installed on the conveying shafts 3; the conveying motor is arranged outside the shell 1, and the conveying motor (not shown) is connected to any one of the conveying shafts 3; the conveying chain 5 is respectively meshed and connected with the two conveying gears 4; the plurality of supporting plates 6 are respectively installed on the conveying chain 5, and the supporting plates 6 are respectively connected to the feeding chute 2 are located on the same vertical plane, and the thickness of the supporting plate 6 is smaller than the width of the feeding chute 2; the hopper 13 is installed on the top plate of the shell 1, and the discharge port of the hopper 13 is aligned with the feeding chute 2; the positioning chute 14 is a fan-shaped structure, and the positioning chute 14 is aligned and connected with one end of the feeding chute 2; the rotating device includes a support plate 8, a rotating shaft 9, an impeller 10 and a torsion spring 11, and the support plate 8 is installed on the top plate of the shell 1; the rotating shaft 9 can rotate The rotating shaft 9 passes through the support plate 8, and limit nuts 901 are arranged at both ends of the rotating shaft 9; the impeller 10 is installed on the rotating shaft 9; a plurality of blades 1001 are arranged on the impeller 10, and the blades 1001 are located on the same vertical plane as the feeding slide, and the thickness of the blades 1001 is smaller than the width of the feeding slide 2; the torsion spring 11 is sleeved on one end of the rotating shaft 9, and one end of the torsion spring 11 is placed on the support plate 8, and the other end is fixed on the rotating shaft 9.

[0028] Based on the above scheme, see Figure 4, start the conveying motor (not shown), the conveying motor drives the conveying shaft 3 to rotate, thereby realizing the rotation of the conveying gear 4, and the conveying chain 5 moves synchronously, driving the supporting plate 6 to slide in the feeding chute 2; the shrimp is put into the feeding chute 2, because the whole shrimp body 12 is not a single width, when it is put into the feeding chute 2, it will be stuck in the feeding chute 2, and the supporting plate 6 pushes the shrimp body 12, so that the shrimp body 12 follows the supporting plate 6 to slide in the feeding chute 2, realizing uniform feeding of each shrimp, and ensuring that the posture of the shrimp body 12 is consistent during the transportation process. When the support plate 6 with the shrimp is transported to the position of the rotating device, the end of the blade 1001 of the rotating device first contacts the shrimp body 12. As the support plate 6 moves forward, the blade 1001 is pushed, causing the blade 1001 to slowly rotate around the shaft 9. At the same time, the contact area between the blade 1001 and the shrimp body 12 gradually increases, and the blade 1001 and the support plate 6 gradually squeeze the shrimp body 12. Finally, when the blade 1001 is perpendicular to the conveyor belt, the shrimp body 12 is completely straightened, completing the straightening of the shrimp body 12. The support plate 6 continues to move forward, and the blade 1001 continues to rotate and rise around the shaft 9 until the support plate 6 leaves the rotating device. Due to the action of the torsion spring 11, the blade 1001 can overcome its own gravity and maintain its position without falling. At this time, another blade 1001 is already in place to straighten another shrimp body 12, and the straightening of the shrimp body 12 continues. Figure 5 When the shrimp body 12 is transported to the discharge end of the feeding chute 2, due to the action of the positioning chute 14, the shrimp body 12 will remain straight and follow the support plate 6 to turn. When it turns to the discharge end of the positioning chute 14, the shrimp body 12 loses the restraint of the positioning chute 14 and falls. Because the shrimp head is heavier, the shrimp body 12 falls head down.

[0029] As a preferred solution, the bottom of the housing 1 is provided with supporting feet 102. Specifically, the supporting feet 102 can make the conveying device stable for conveying and also facilitate the transportation and movement of the device.

[0030] See also Figure 6 As a preferred solution, the supporting plate 6 includes a connecting portion 601, a supporting portion 602 and a limiting portion 603, wherein the connecting portion 601 is mounted on the conveying chain 5; the supporting portion 602 is mounted on the supporting portion 602; the limiting portion 603 is mounted on the top of the supporting portion 602, and the limiting portion 603 and the supporting portion 602 form a "7"-shaped structure. Specifically, the supporting plate 6 is connected to the conveying chain 5 through the connecting portion 601, so that the installation and disassembly of the supporting plate 6 is convenient, and the subsequent maintenance and replacement are convenient. The "7"-shaped supporting plate 6 can prevent the shrimp body 12 from sliding out of the feeding chute 2 when pushing the shrimp body 12, thereby ensuring the stability of the transmission.

[0031] As a preferred solution, the length of the supporting plate 6 is not less than the depth of the feeding chute 2. Specifically, the supporting plate 6 can extend out of the feeding chute 2, so that when conveying a larger shrimp body 12, the thrust of the supporting plate 6 can act on the entire shrimp body 12, making the conveying of the shrimp body 12 more stable.

[0032] As a preferred solution, the feeding chute 2 is a V-shaped structure. Specifically, the V-shaped structure can further prevent the shrimp body 12 from sliding off the feeding chute 2.

[0033] As a preferred solution, the feeding chute 2 includes a first side plate 201 and a second side plate 202 which are opposite and spaced apart, and the top edges of the first side plate 201 and the second side plate 202 are respectively connected to the top plate of the shell 1. Specifically, the feeding chute 2 is formed by two side plates, which is convenient and fast, and has low manufacturing cost.

[0034] As a preferred solution, the connection between the first side plate 201 and the second side plate 202 and the top plate of the housing 1 is configured as an arc surface structure. Specifically, the arc surface structure can prevent the shrimp body 12 from being scratched or the hand from being injured when the shrimp body 12 is put into the housing.

[0035] As a preferred solution, a plurality of the supporting plates 6 are evenly arranged on the conveying chain 5. Specifically, evenly arranging the supporting plates 6 can make the conveying intervals of the shrimp bodies 12 uniform, thereby improving the controllability of the conveying.

[0036] As a preferred solution, a limiting guide rail is provided in the housing 1, a limiting slideway is provided in the limiting guide rail, and the conveying chain 5 passes through the limiting slideway.

[0037] As a preferred solution, the blades 1001 are provided with three, and the angle between adjacent blades 1001 is 120°. Specifically, the three blades 1001 can ensure the stability of the entire rotating device, and the blades 1001 can maintain better balance during the rotation process, and the straightening effect will not be poor due to too frequent straightening frequency.

[0038] The use process of the present invention is as follows: start the conveying motor (not shown), the conveying motor drives the conveying shaft 3 to rotate, thereby realizing the rotation of the conveying gear 4, and the conveying chain 5 moves synchronously, driving the supporting plate 6 to slide in the feeding chute 2; put the shrimp into the feeding chute 2, because the whole shrimp body 12 is not a single width, when it is put into the feeding chute 2, it will be stuck in the feeding chute 2, and the supporting plate 6 will push the shrimp body 12, so that the shrimp body 12 follows the supporting plate 6 to slide in the feeding chute 2, realizing uniform feeding of each shrimp, and ensuring that the posture of the shrimp body 12 is consistent during the transportation process. When the support plate 6 is carrying the shrimp to the position of the rotating device, the end of the blade 1001 of the rotating device first contacts the shrimp body 12. As the support plate 6 moves forward, the blade 1001 is pushed, causing the blade 1001 to slowly rotate around the rotating shaft 9. At the same time, the contact area between the blade 1001 and the shrimp body 12 gradually increases, and the blade 1001 and the support plate 6 gradually squeeze the shrimp body 12. Finally, when the blade 1001 is perpendicular to the conveyor belt, the shrimp body 12 is completely straightened, completing the straightening of the shrimp body 12; the support plate 6 continues to move forward, and the blade 1001 continues to rotate and rise around the rotating shaft 9 until the support plate 6 leaves the rotating device. Due to the action of the torsion spring 11, the blade 1001 can overcome its own gravity and maintain its position without falling. At this time, another blade 1001 is already in place to straighten another shrimp body 12, and the working cycle of straightening the shrimp body 12 is continuous. When the shrimp body 12 is conveyed to the discharge end of the feeding chute 2, due to the action of the positioning chute 14, the shrimp body 12 will remain straight and follow the support plate 6 to turn. When it turns to the discharge end of the positioning chute 14, the shrimp body 12 loses the restraint of the positioning chute 14 and falls. Because the shrimp head is heavier, the shrimp body 12 falls headfirst.

[0039] In summary, the preferred embodiment of the present invention provides a positioning and conveying shrimp stall device. Compared with the prior art, the positioning and conveying shrimp stall device of the present invention is provided with a feeding chute 2. Since the width of the shrimp body 12 is not single, when the shrimp body 12 is put into the feeding chute 2, the shrimp body 12 will be stuck in the feeding chute 2 and maintain a fixed posture, and the supporting plate 6 and the feeding slide are located on the same vertical plane. When the supporting plate 6 moves with the conveying material strip, it will push the shrimp body 12 to slide along the feeding chute 2 without changing the posture of the shrimp body 12, so as to realize the intermittent feeding of shrimps one by one, and ensure that the posture of the shrimp body 12 is consistent during the conveying process, which is convenient for the subsequent processing technology. At the same time, the rotating device is used to squeeze the shrimp body 12 through the blade 1001 and the supporting plate 6 to straighten the shrimp body 12, so as to realize the straightening of the shrimp body 12 during the conveying process of the shrimp body 12, thereby improving the processing efficiency and reducing the processing cost. In addition, the shrimps are fed into the feeding chute 2 through the hopper 13, which improves the feeding efficiency and ensures that the shrimp bodies 12 can be accurately fed into the feeding chute 2. A positioning chute 14 is provided to position the shrimp bodies 12 when the shrimp bodies 12 are output, ensuring that the shrimp bodies 12 enter the next process with their heads falling first, and preventing the shrimp bodies 12 from falling to the sides of the shell 1.
