[0044] The feeding device 20 is connected to the feeding end of the shelling device 30 and is used to transport the pre-treated crayfish to the shelling device 30;

[0045] The shelling device 30 is used to separate the shell and meat of the crayfish;

[0046] The discharging device 40 is connected to the discharging end of the shelling device 30 and is used to receive the shrimp shells and shrimp meat;

[0047] The collecting box 50 is connected to the discharging end of the discharging device 40 and is used to collect shrimp shells and shrimp meat;

[0048] The water collecting bucket 60 is connected between the feeding device 20 and the collecting box 50 to receive the overflowed water from the feeding device 20 and transport it to the collecting box 50;

[0049] The filter screens 51 are arranged at intervals in the collecting box 50 to filter the shrimp shells.

[0050] ① In this utility model, reference is made to Figure 1 The caught shrimps are first frozen and stirred in ice water in the pretreatment device 10, so that the shrimp shells and shrimp meat are initially separated. The pretreatment device is a stirring tank. The shrimps are stirred by a stirring paddle in the stirring tank, so that the shrimp shells and shrimp meat are initially separated. In order to improve the pretreatment effect, ice water can be added to the stirring tank. The ice water can shrink the shrimp meat and further improve the effect of the initial separation. The pretreated shrimps are transported to the feeding device 70 through the feeding device 20. The feeding device 70 has two functions, one is to transport the crayfish, and the other is to make the crayfish in the feeding device 70 change from a curled state to a straight state; further, the feeding device 20 and the discharging device 40 are both configured as conveyor belts;

[0051] In one embodiment, a crayfish shelling assembly line also includes a feeding device 70 connected between the loading device 20 and the shelling device 30, which is used to transport the crayfish to the shelling device 30, and the feeding device 70 includes a receiving hopper 71, which has a receiving trough 711; a plurality of discharge barrels 72, which are arranged on the receiving hopper 71 and connected to the receiving trough 711; a first auger 73, which is arranged in the receiving trough 711 and extends along the length direction of the receiving trough 711; a second auger 74, which is arranged in the discharge barrel 72 and extends along the length direction of the discharge barrel 72; a second drive assembly 75, whose output end is connected to the first auger 73; a third drive assembly 76, whose output end is connected to the second auger 74; after the action of the first auger 73 and the second auger 74, the crayfish are not only roughly corrected to a straight state, but also fall one by one onto the shelling device 30.

[0052] ②Reference Figure 1-2 and 4, in the shelling device 30, the shelling device 30 includes a fixed frame 31; a plurality of groups of shelling rollers, each group of shelling rollers includes a large roller 32 and a first small roller 33 and a second small roller 34 arranged above the large roller 32 and located on both sides of the large roller 32, one end of the large roller 32, the first small roller 33 and the second small roller 34 are connected to one end of the fixed frame 31 through a bearing; a first driving assembly 35 is arranged at the other end of the fixed frame 31 and connected to the other ends of the large roller 32, the first small roller 33 and the second small roller 34;

[0053] The first drive assembly 35 preferably includes a first motor 351 and a gear set, which are respectively meshed with the output end of the first motor 351 and the other ends of the large drum 32, the first small drum 33 and the second small drum 34; specifically, the feeding device 70 conveys the crayfish to between the first small drum 33 and the large drum 32 and between the second small drum 34 and the large drum 32, wherein the first drive assembly 35 drives the large drum 32, the first small drum 33 and the second small drum 34 to rotate, so that the crayfish rubs between the first small drum 33 and the large drum 32 and between the second small drum 34 and the large drum 32, thereby peeling the shrimp shell and dropping it to the bottom of the shrimp peeling roller, and then being collected by the discharging device 40 and transported to the collecting box 50, and the shrimp meat falls from the top of the peeling roller to the discharging device 40 under the impact of the water flow, and is also collected by the discharging device 40 and transported to the collecting box 50.

[0054] ③Reference Figure 2 and 4 In one embodiment, a crayfish peeling line further includes a deceleration device 80 disposed above the peeling device 30, for slowing down the travel speed of the crayfish on the peeling device 30; in the deceleration device 80, the deceleration device 80 includes a fourth drive assembly 81 and a plurality of brush rollers 82: the brush rollers 82 are connected to the top of the peeling device 30 and rotate at intervals along the travel direction of the crayfish; the fourth drive assembly 81 is connected to the brush roller 82, for driving the brush roller 82 to rotate and roll the crayfish to slow down the travel speed of the crayfish on the peeling device 30;

[0055] Specifically, the shelling roller is arranged longitudinally, and the brush roller 82 is located above the shelling roller and arranged transversely. The brush roller 82 rotates in the direction opposite to the moving direction of the crayfish under the drive of the fourth driving assembly 81, so that the crayfish is brushed by the brush on the brush roller 82, thereby slowing down the moving speed of the crayfish on the shelling device 30, increasing the residence time of the crayfish in the shelling device 30, and further correcting the straightening state of the shrimp body; of course, the moving speed of the crayfish can be adjusted by adjusting the number of brush rollers 82, the distance between the brush roller 82 and the shelling device 30, the rotation speed of the brush roller 82, etc., which will not be elaborated here.

[0056] ④ The separated shrimp shells and shrimp meat enter the collecting box 50, and the water flowing out of the feeding device 20 in the process of conveying crayfish falls into the water collecting bucket 60. The water collecting bucket 60 has a water outlet, which is located above the collecting box 50 or connected to the collecting box 50 through a pipeline, so that the water in the water collecting bucket 60 is conveyed to the collecting box 50; and in the collecting box 50, since the weight of the shrimp shell is lighter than the shrimp meat, the shrimp shell floats on the water surface of the collecting box 50, and the shrimp meat sinks to the bottom of the collecting box 50. After filtering through the filter net 51, the shrimp shell can be separated very conveniently; further, a roller is installed at the bottom of the collecting box 50, which can be very conveniently transferred to the pretreatment device 10 or the feeding device 20 for the second shelling process.

[0057] ⑤The advantage of the utility model is that the residual water in the crayfish transportation process can be collected and sent into the collection box through the above structure, and the separated shrimp shells and shrimp meats are immersed in the collection box and separated by the filter net, which facilitates transportation and improves the shelling rate, and has very good practicality.

[0059] As a preferred embodiment of the third drive assembly 76, the third drive assembly 76 includes a third motor 761, a third gear 762 connected to the output end of the third motor 761, and a plurality of fourth gears connected to the second auger 74, the third gear 762 is meshed with the fourth gear and two adjacent fourth gears are meshed with each other.
