Detailed Description
The present invention will be described in further detail with reference to specific embodiments.
As shown in fig. 1-7, a rotating disc type prawn feeding device comprises a circular chassis, a positioning groove, a central column, a coarse adjustment mechanism, a detection mechanism and a fine adjustment mechanism, and specifically comprises a central column 2, a circular chassis 1, a movable pin 4, a positioning groove 3, a flexible contact pin 6, a silica gel block 5, a ladder prawn sweeping piece 11, a prawn sweeping arm 7, a tail aligning plate 8, a sliding sleeve 10, a prawn body positioning piece 12, a flexible hairbrush 9 and the like.
The central column 2 is fixed, and the circular chassis 1 is driven by the motor to do intermittent rotary motion in the counterclockwise direction. 4 telescopic slots 21 are evenly distributed on the circular chassis 1 along the circumferential direction, the cross section of each telescopic slot 21 is in a shape like a Chinese character 'tu', the telescopic slots can be mutually embedded with the square body on the lower part of the movable pin 4 and extend out along the radial direction of the circular chassis 1 without exceeding the edge of the circular chassis 1.
The cross section shapes of the square bodies at the lower parts of the 4 telescopic grooves 21 arranged along the circumferential direction of the circular chassis 1 and the movable pins 4 are the same, the two telescopic grooves can be mutually embedded and connected in a clearance fit mode, so that the movable pins 4 can drive the positioning grooves 3 to freely slide in the telescopic grooves 21 along the radial direction, and the mounting positions of the movable pins in the telescopic grooves are selected according to the length of prawns and are fixed.
The positioning groove 3 is divided into an inner section and an outer section. The inner section is close to the central column 2, the inner surface is smooth, and the shrimp body can freely slide on the inner section. The outer section is suspended in the circular chassis 1, the inner surface is carved with the longitudinal stripe at equal intervals, and the shrimp body is easy to be blocked by the stripe when moving on the outer section, thus being difficult to slide. The cross section of the positioning groove 3 is in a V shape, and according to the characteristics of narrow distance between two sides of the prawn and wide distance between the abdomen and the back of the prawn, the positioning groove 3 can stably clamp the prawn body and prevent the prawn body from turning on one side. The outer section of the positioning groove 3 and the circular chassis 1 form a certain angle, the angle of the V-shaped cross section is gradually reduced, the tail of the prawn can be supported, and three-point support is formed by the outer section of the positioning groove and supporting points on two sides, so that the position and the posture of the prawn on the positioning groove 3 are more stable. Two rectangular channels are arranged on the positioning groove 3, when the device is operated, the longitudinal rectangular channel close to the middle part of the inner section can be used for the flexible contact pin 6 to pass through, and the transverse rectangular channel close to the central column 2 of the inner section can be used for the ladder shrimp sweeping piece 11 to pass through. The lower parts of the positioning grooves 3 are connected through a cylinder on the upper part of the movable pin 4, so that the left and right groove plates can be freely opened and closed, and the silica gel block 5 can be naturally pressed.
Every two silica gel blocks 5 are in a group and symmetrically fixed at two sides of the outer surface of the positioning groove 3. Silica gel block 5 comprises cuboid and the right angle triangle-shaped body on upper portion of lower part, and the cuboid bottom is fixed with circular chassis 1, and the hypotenuse of right angle triangle-shaped body closely laminates with 3 surfaces of constant head tank. When the positioning groove 3 is stressed to naturally hang down, the silica gel block 5 can deform slightly and can support the positioning groove 3. The pressure sensitive component 51 is arranged in the silica gel block 5, so that the pressure change of the silica gel block 5 can be sensed in real time. Whether the posture of the prawns in the positioning groove 3 is qualified or not can be judged through the pressure difference value of the silica gel blocks 5 on the two sides.
The ladder shrimp sweeping blade 11, the flexible contact pin 6 and the shrimp sweeping arm 7 are connected with the central column 2 in sequence by taking the anticlockwise direction of the movement of the circular chassis 1 as a reference. The stepped prawn sweeping slice 11 consists of 3 eccentric circular arc plates with the same radius and is used for coarse adjustment of the tail of the prawn. The transverse rectangular channel on the inner section of the positioning groove 3 close to the central column 2 corresponds to the position of the ladder shrimp sweeping piece 11, and the ladder shrimp sweeping piece 11 can smoothly pass through the transverse rectangular channel. Along with the rotation of the circular chassis 1, the acting force of the stepped shrimp sweeping pieces 11 on the prawns in the positioning grooves 3 can be decomposed into radial force and force vertical to the radial direction. Wherein, the radial force pushes the prawns to move along the positioning groove 3, the force vertical to the radial direction presses the prawns on the side wall of the positioning groove 3 clockwise, friction force is generated, and the prawns are prevented from sliding. The arc plate is eccentrically arranged, so that the radial force applied to the prawns is gradually increased, and the force perpendicular to the radial direction is gradually reduced, thereby being beneficial to the prawns to slide on the positioning groove 3. 3 arc boards set up to the echelonment, and the distance of mid point to center post 2 increases in proper order along circular chassis 1 anticlockwise, and two arc board hookup location set up one section radial ascending distance, and the shrimp has the afterbody to adjust step by step on the way in the motion, has solved eccentric settings and has brought the too big problem of the radial power of initial perpendicular to, prevents that one time tail alignment from adjusting too big and producing the shrimp and block, the phenomenon of shearing.
The radial position of the flexible contact pin 6 corresponds to the longitudinal rectangular channel position on the inner section of the positioning groove 3, and the flexible contact pin 6 can smoothly pass through the rectangular channel in the telescopic range of the positioning groove 3 in normal operation; the distance between the flexible contact pin 6 and the bottom of the positioning groove 3 in the vertical direction is smaller than the height of a conventional shrimp body, so that the flexible contact pin 6 can touch the shrimp body when the positioning groove 3 passes through, and the flexible contact pin is used for detecting whether the passing positioning groove 3 contains prawns. Wherein the height of the conventional shrimp body is about 20-30 mm.
One end of the shrimp sweeping arm 7 is fixed on the central column 2, the other end of the shrimp sweeping arm is fixed with a tail aligning plate 8, the middle section of the shrimp sweeping arm is provided with a sliding sleeve 10, and the sliding sleeve 10 is driven by a motor and can freely move in the radial direction of the circular chassis 1; the tail aligning plate 8 is a cuboid plate with a three-layer structure, a rigid material layer, an interlayer and a flexible material layer are respectively arranged from far to near from the central column 2, and a pressure sensitive component 51 is arranged in the interlayer and can detect the pressure applied to the flexible material layer along the radial direction. The flexible material layer can well absorb impulse, and the influence of instantaneous pressure sudden change on the judgment of the pressure sensitive component 51 is prevented.
The flexible brush 9 is used for fine adjustment of alignment of the tail of the prawn, the radial cross section of the flexible brush is in an isosceles triangle shape, the angle of the top angle is equal to the maximum angle of the inner section of the positioning groove 3, and the height of the end part of the longest brush is the same as that of the bottom of the positioning groove 3, so that the cross section of the flexible brush 9 can completely cover the cross section of the positioning groove 3, and no dead angle is left when the flexible brush sweeps across the positioning groove 3. When the prawns move, the materials are likely to be damaged due to the overlarge local acting force of the flexible brush 9. Along the radial direction away from the circular chassis 1, the length of the brush hair is gradually reduced, and the brush hair brushing the prawns is from short to long. If the short bristles cannot stir the prawns, the short bristles can cross the prawns along with the forward movement of the sliding sleeve 10, and the pushing acting force cannot be generated; the long bristles can follow up and be blocked by the prawns to generate acting force on the prawns. The force applied to the prawns is gradually increased along with the increase of the piled longer bristles, and the prawns are finally stirred. Therefore, the force of the prawns is gradually increased and then becomes stable, the increasing speed is gentle, and the prawns are not easily damaged.
The shrimp body positioning piece 12 is composed of a left piece and a right piece, is obliquely arranged on one side of the sliding sleeve 10 away from the central column 2, and has the same oblique direction as the positioning groove 3, preferably, the oblique angle is 15 degrees, and an opening formed below the positioning groove 3 is smaller than the positioning groove 3; the shrimp body normal position piece 12 is the flexbile plate, and the upper portion is the rectangle structure, and one side that the center post 2 was kept away from to lower part is a section circular arc. In the radial movement process of the sliding sleeve 10, the circular arc section of the shrimp body positioning sheet 12 is always firstly contacted with the positioning groove 3. The arc shape of the lower part of the shrimp body positioning sheet 12 can enable the positioning groove 3 to generate a component force vertical to the shrimp body positioning sheet 12, so that the component force is bent and deformed, the positive pressure is reduced, and the lower part of the shrimp body positioning sheet 12 can conveniently slide in.
The device is used as follows:
before the work, whether the circular chassis 1 and the sliding sleeve 10 can move freely or not is checked, and whether the positioning groove 3 can naturally lean against the silica gel block 5 or not is checked. The position of the movable pin 4 on the circular chassis 1 is adjusted according to the tail length required to be reserved for the prawn variety, and the movable pin is fixed.
With the anticlockwise intermittent rotation of the circular chassis 1 driven by the motor, the prawns can sequentially pass through 4 intervals as shown in figure 1. Firstly, the prawns enter the filling area through the modes of conveying by a conveyor belt or clamping by a manipulator and the like, and are placed into the positioning groove 3 in the posture that the head faces the central column 2 and the back faces upwards. The longitudinal stripes on the outer section of the positioning groove 3 can clamp the shrimp legs, so that the shrimp legs cannot be thrown out of the device due to centrifugal action or machine vibration.
Then the circular chassis 1 rotates 90 degrees, and the prawns reach a detection area. During the rotation process, the prawns and the stepped prawn sweeping slices 11 are mutually contacted and are gradually pushed outwards along the positioning grooves 3. The arc-shaped structure of the stepped shrimp sweeping piece 11 has certain elasticity, the change rate of the shrimp body is uniform when the shrimp body is pushed, local pressure mutation cannot be generated, and the shrimp is not easy to damage. The 3-section structure of the ladder prawn sweep slice 11 can slowly push the prawns step by step, and the prawns are gradually adjusted in a tail-aligning manner when being converted from one circular arc plate to another circular arc plate, so that the phenomenon of shearing between the prawns and the ladder prawn sweep slice 11 due to overlarge adjustment is prevented.
The round chassis 1 rotates 90 degrees again, the prawns reach the tail aligning area, and in the rotating process, the flexible contact pin 6 touches the prawns and generates a vibration signal; if the positioning groove 3 does not contain prawns for some reasons, a stable signal is generated all the time, the system can judge whether the positioning groove 3 contains the prawns according to the captured signal type, and then whether the next tail trimming operation needs to be skipped is selected according to the judgment result, so that the overall processing efficiency can be improved.
The alignment of the tail part of the prawn can be realized in the tail aligning area. After the prawns reach the tail aligning area, the sliding sleeve 10 reciprocates on the shrimp sweeping arm 7 from the initial position close to the central post 2, and the flexible brush 9 below the sliding sleeve 10 gradually moves along the radial direction to push the prawns to reach the required position.
The prawns move towards the tail aligning plate 8 on the positioning groove 3, the pressure generated by aligning the prawns with the tail aligning plate 8 is detected through the pressure sensitive assembly 51 in the interlayer, whether the prawns reach the required position in the radial direction can be judged by comparing the preset pressure with the actual pressure, and if the pressure meets the requirement, the sliding sleeve 10 can return to the initial position.
The prawns are often in a soaked state when being treated, the friction force between the prawns and the positioning groove 3 is increased, the prawns can be adhered to one side of the positioning groove 3 under the action of water surface tension and friction force, and the prawns can not be ensured to fall off by shifting the flexible brush 9. The silica gel block 5 is deformed by pressure, and the pressure sensitive component 51 inside detects the pressure value. In the tailgating area, the pressure sensitive component 51 compares the size of the left data and the size of the right data, and if the difference value exceeds a certain threshold value, the situation that the pressure sensitive component is stuck to one side of the positioning groove 3 is judged.
The inclined direction of the shrimp body positioning piece 12 arranged on the sliding sleeve 10 is the same as that of the positioning groove 3, the whole body is made of flexible materials, and when the sliding sleeve 10 moves, the shrimp body positioning piece 12 can slide into the positioning groove 3. The inclination angle of the prawn body positioning sheet 12 is always smaller than the inclination angles of the left and right positioning grooves 3, and the prawn body positioning sheet can cling to the side wall of the positioning groove 3 after sliding in and scratch the adherent prawn. Under the action of gravity, the prawns can fall off from one side and then are pushed to a required position through the flexible brush 9. In this process, the pressure sensitive assembly 51 will constantly monitor the pressure and move the sliding sleeve 10 back and forth until the pressure difference is smaller than a certain value, the sliding sleeve 10 returns to the initial position to complete the tail alignment.
The posture of the prawns on the positioning groove 3 meets the feeding requirement through the adjustment of the tail aligning area. The circular chassis 1 rotates 90 degrees to reach the feeding area to finish feeding, and the prawn can be accurately clamped by the machine executing the next process.
The above embodiments are preferred embodiments of the present invention, but the present invention is not limited to the above embodiments, and any other changes, modifications, substitutions, combinations, and simplifications which do not depart from the spirit and principle of the present invention should be construed as equivalents thereof, and all such changes, modifications, substitutions, combinations, and simplifications are intended to be included in the scope of the present invention.
