Description

TECHNICAL FIELD

[0001] The present application belongs to the field of crayfish processing, and particularly relates to a crayfish processing positioning device. BACKGROUND

[0002] Crayfish processing is an industrialized production process of converting live crayfish into instant, quick-frozen or flavored products through a standardized process. During the crayfish processing process, the crayfish are cleaned and sterilized. The cleaning of the crayfish often uses the cavitation effect of ultrasonic waves emitted by an ultrasonic vibration plate to remove the mud on the surface of the crayfish, and the crayfish are sterilized by ozone water immersion, that is, ozone gas is injected into the water to form dissolved ozone.

[0003] Although the crayfish cleaning and sterilizing device in the prior art can use an ultrasonic vibration plate and an ozone generator to clean and sterilize the crayfish placed in the water, the crayfish are in a random posture during cleaning, which can cause part of the crayfish bodies not to contact the effective vibration area, affecting the cleaning effect. In addition, the removal rate of parasites and pathogens in narrow gaps such as gill folds and foot joints is insufficient through ultrasonic cleaning alone, and the random posture of the crayfish groups in the water can also cause uneven distribution of the contacted ozone, affecting the sterilization effect.

DETAILED DESCRIPTION

[0028] In order to make the technical means, creative features, purposes and effects of the present application easy to understand, the present application is further described below in conjunction with specific embodiments.

[0029] As shown in Figures 1 to 8 The small crayfish processing positioning device of the embodiment of the present application comprises a support platform 1, a cleaning box 2 fixed to the top of the support platform 1, a plurality of ultrasonic vibration plates 3 fixed to the inner walls of the cleaning box 2 at both ends, an ozone generator 5 arranged on one side of the support platform 1, an exhaust duct 6 fixed to the bottom of the inner cavity of the support platform 1, and a movable positioning mechanism acting on the crayfish body. One side of the exhaust duct 6 penetrates through the support platform 1 and is fixedly arranged in communication with the output end of the ozone generator 5.

[0030] The movable positioning mechanism comprises a plurality of positioning boxes 4 arranged at the middle position of the inner cavity of the cleaning box 2, a first filter plate 7 slidingly inserted into the inner cavity of the cleaning box 2 at the bottom position of the positioning box 4, a sealing element 8 fixed to the first filter plate 7 extending out of the support platform 1, a driving assembly acting on the positioning box 4, and a pushing assembly arranged at both ends and inside the positioning box 4.

[0031] When the crayfish body needs to be cleaned and disinfected, first, the first filter plate 7 is inserted into the inner cavity of the cleaning box 2, and the sealing element 8 is fixed to one side of the cleaning box 2 by means of bolts, so as to be sealed from one side of the cleaning box 2 under the action of the sealing element 8. Then, the pushing assembly inside the positioning box 4 is operated by the driving assembly, so as to gradually and uniformly add the crayfish body to be cleaned and disinfected into the inside of the positioning box 4. Then, the drain pipe of the cleaning box 2 is sealed, and clean water is added to the inner cavity of the support platform 1 so as to be able to cover the positioning box 4. Then, the ultrasonic vibration plate 3 is turned on so that the ultrasonic vibration plate 3 can emit ultrasonic waves. The cavitation effect can remove the mud and sand on the crayfish body. Since the crayfish body is placed in the inner cavity of the positioning box 4, the crayfish body will not be randomly distributed at a position away from the ultrasonic vibration plate 3 in the inner cavity of the support platform 1.

[0032] Meanwhile, the positioning box 4 is capable of reciprocating along the horizontal direction through the driving assembly, so that the shrimps placed in the inner cavity of the positioning box 4 can be subjected to the scouring effect of the water flow, thereby improving the cleaning effect of the shrimps, preventing the insufficient removal of the parasites and pathogenic bacteria in the narrow gaps such as the gill folds and the foot joints, and enabling the shrimps in the inner cavity of the positioning box 4 to cyclically move up and down through the reciprocating movement of the positioning box 4 along the horizontal direction. Meanwhile, the ozone generator 5 is started to inject ozone into the water body from the exhaust pipeline 6, so that the cyclically moving shrimps can cyclically approach the exhaust pipeline 6, thereby improving the uniformity of the contact of the shrimps in the inner cavity of the positioning box 4 with the anaerobic bacteria, and ensuring the overall sterilization effect.

[0033] As shown in Figures 1 to 8 the driving assembly comprises a rotating shaft 16 rotatably connected to the middle position of one end of the outer surface of the cleaning box 2, a fixed disc 17 fixed to one end of the rotating shaft 16, a contact rod 21 fixed to the surface of one end of the fixed disc 17, a sleeve 20 sleeved on the outside of the contact rod 21, a connecting strip 13 fixed between two adjacent positioning boxes 4, and a movable plate 14 fixed to one side of one of the positioning boxes 4. The movable plate 14 is slidably connected to the inner wall of the cleaning box 2, and the surface of the part of the movable plate 14 extending out of the cleaning box 2 is fixed to the surface of the sleeve 20.

[0034] When the rotating shaft 16 is in a rotating state, the fixed disc 17 is capable of rotating, so that the contact rod 21 performs a circular motion, and under the action of the contact rod 21 contacting the rotating shaft 22 and the limiting action of the inner wall of the cleaning box 2 on the movable plate 14, the sleeve 20 is capable of reciprocating along the horizontal direction, so that under the connecting action of the movable plate 14 and the connecting strip 13, the plurality of positioning boxes 4 are capable of reciprocating along the horizontal direction in the inner cavity of the cleaning box 2.

[0035] As shown in Figures 1 to 8 the driving assembly further comprises a motor 15 fixed to the bottom of one end of the outer surface of the cleaning box 2, a first bevel gear 18 fixedly sleeved on the outer periphery of the rotating shaft 16, and a second bevel gear 19 fixedly sleeved on the upper and lower ends of the output end of the motor 15. The first bevel gear 18 and the second bevel gear 19 at the adjacent positions are in meshing connection.

[0036] When the motor 15 is started, the two second bevel gears 19 rotate, so that the rotating shaft 16 is capable of being in a rotating state under the meshing action between the second bevel gears 19 and the first bevel gear 18.

[0037] As shown in Figures 1 to 8As shown, the pushing assembly comprises a support plate 26 arranged at the middle of the two ends of the positioning box 4, a connecting seat 27 arranged in a U shape on the surface of the support plate 26 and the one end of the positioning box 4, a rotating shaft 22 rotatably connected to the upper and lower ends of the surface of the support plate 26, a belt pulley 23 fixedly sleeved on the outer surface of the rotating shaft 22, a connecting belt 24 sleeved between two adjacent belt pulleys 23, a circular gear 25 fixedly sleeved on the outer surface of one of the rotating shafts 22 away from the belt pulley 23, and a toothed plate 12 fixed to the inner wall of the cleaning box 2 at the bottom of the ultrasonic vibrating plate 3. The toothed plate 12 is in meshing connection with the adjacent plurality of circular gears 25.

[0038] When the positioning box 4 moves back and forth in the horizontal direction, the circular gear 25 will mesh with the adjacent toothed plate 12, so that one of the rotating shafts 22 rotates, and the other belt pulley 23 also rotates under the connection of the connecting belt 24, so that the connecting belt 24 is in an active state.

[0039] As shown in the figure, Figures 1 to 8 The pushing assembly further comprises a plurality of moving plates 28 fixed to the outer surface of the connecting belt 24, a support shaft 29 fixed to one end of the moving plate 28, a partition plate 30 fixed to the middle of the two support shafts 29, a center plate 31 fixed to the middle of the two adjacent support plates 26, and a hydrophobic component acting on the two sides of the positioning box 4. The two sides of the partition plate 30 are in close contact with the inner surface of the one end of the positioning box 4 and the outer surface of the support plate 26.

[0040] The partition plate 30 is arranged at the middle of the opening of the one end of the positioning box 4 and the support plate 26, so as to be clamped and limited by the two, so that when the connecting belt 24 moves and drives the moving plate 28 to move, the plurality of partition plates 30 can move around the inner cavity of the positioning box 4. When the crayfish is added to the inner cavity of the positioning box 4, the crayfish is added to the gap between the plurality of partition plates 30, so that the crayfish in the inner cavity of the positioning box 4 can move up and down under the movement track of the partition plate 30. The gap between the partition plates 30 can be filled by the center plate 31. Due to the action of the hydrophobic component, the flushing efficiency of the crayfish can be improved when the positioning box 4 moves in the horizontal direction.

[0041] As shown in the figure, Figures 1 to 8 The hydrophobic component penetrates the first guide hole 32 opened at the top of the two sides of the positioning box 4 and the second guide hole 33 opened at the bottom of the two sides of the positioning box 4. The hole diameter of the first guide hole 32 and the second guide hole 33 close to the inner cavity of the positioning box 4 is smaller than the hole diameter away from the inner cavity of the positioning box 4. The inner cavity of the first guide hole 32 is arranged in an inclined manner.

[0042] The first guide hole 32 located at the top of both sides of the cleaning tank 2 is inclined, so that the water flow can be obliquely into the water, guide the water flow to form a rotating scouring, cover the shrimp body foot joint, the second guide hole 33 at the bottom of both sides is a straight hole, which produces a vertical jet impact on the shrimp abdomen, and the inclined hole pushes the shrimp body to roll over, thereby improving the effect of water flow scouring the shrimp body. Due to the difference in hole diameter, a flow velocity gradient can be formed to enhance the shear force of the water flow, thereby further improving the effect of water flow scouring the shrimp body.

[0043] As shown in Figures 1 to 8 The movable positioning mechanism further includes a protective stirring assembly, which includes a stirring rod 11 rotatably connected to the surface of one end of the cleaning tank 2 near the motor 15 and a third bevel gear 34 extending out of the cleaning tank 2 from the outer peripheral surface of the stirring rod 11, which is in meshing connection with the second bevel gear 19 at the adjacent position.

[0044] When the motor 15 is started, the second bevel gear 19 can be rotated, so that the stirring rod 11 can be in a rotating state under the meshing action between the second bevel gear 19 and the third bevel gear 34, so that the water body can be stirred when the ozone generator 5 and the exhaust duct 6 can inject ozone into the water body, so that the ozone distribution at the bottom of the water body is more uniform. The ozone sterilization operation needs to be carried out after the ultrasonic vibration plate 3 ultrasonic cleaning shrimp body.

[0045] As shown in Figures 1 to 8 The protective stirring assembly further includes a second filter plate 9 arranged at both ends of the exhaust duct 6 located in the inner cavity of the cleaning tank 2 and a baffle 10 fixed to the top of the two second filter plates 9 in an inverted V shape.

[0046] The setting of the baffle 10 can avoid the dirt such as silt generated during the cleaning process from directly falling through the first filter plate 7 to the surface of the exhaust duct 6 to block the exhaust port of the exhaust duct 6, and the setting of the second filter plate 9 can prevent the dirt and other impurities distributed in the water body at both ends of the exhaust duct 6 from contacting the exhaust duct 6, thereby playing a protective role for the exhaust duct 6.

[0047] When the shrimp body is recovered after the cleaning and sterilization is completed, first, a certain amount of water is discharged through the drain pipe of the cleaning tank 2, so that the water in the inner cavity of the cleaning tank 2 is lower than the first filter plate 7, and in this process, the mud and other impurities cleaned out will be discharged with the water outside the cleaning tank 2, by disassembling the bolts at the connection between the sealing piece 8 and the cleaning tank 2, and then sliding the first filter plate 7 to make the first filter plate 7 separate from the inside of the cleaning tank 2, since the positioning tank 4 reciprocates along the horizontal direction, the bottom of the positioning tank 4 is attached to the surface of the first filter plate 7, when the first filter plate 7 is slid out, the bottom of the positioning tank 4 is open, and then the positioning tank 4 can move along the horizontal direction by the driving assembly, so that the partition plate 30 moves, so that the shrimp body placed in the inner cavity of the positioning tank 4 can fall out of the outside of the positioning tank 4, thereby completing the recovery of the shrimp body.

[0048] The above front, rear, left, right, up and down are based on the drawings of the specification Figure 1 The front of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on according to the standard of the human observation angle.

[0049] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the present application, and various changes and improvements can be made without departing from the spirit and scope of the present application, and these changes and improvements all fall within the scope of the present application.
