[0020] like Figures 3 to 6 As shown, in this embodiment, the egg tray intermittent rotary conveyor includes a frame, on which a chain mechanism A10 is horizontally arranged and intermittently driven to rotate by a driving mechanism, and egg tray positioning brackets A20 are installed at intervals on the chain mechanism, and the egg tray positioning brackets are provided with a pair of positioning bosses A21 for cooperating with the recessed portions on the bottom surface of the egg tray.

[0021] In this embodiment, in order to better install the egg tray positioning bracket, an egg tray positioning bracket is installed at every other chain link on the chain mechanism.

[0022] In this embodiment, in order to better install the egg tray positioning bracket, the chain mechanism includes a plurality of chain links A11 that are rotatably connected head to tail in sequence to form a chain. Each chain link has a pair of long plate-shaped chain plates A12 arranged in parallel up and down, and two adjacent chain links are rotatably connected via a vertical pin shaft A13 and a shaft sleeve A14, so that the chain rotates through the driving mechanism, and the egg tray positioning bracket is conveniently installed on the long plate-shaped chain plates.

[0023] In this embodiment, in order to allow the chain mechanism to better complete the smooth transportation of the egg tray, the upper and lower ends of the vertical pin shaft are rotatably connected to the upper roller A15 and the lower roller A16, and the front and rear sides of the frame are transversely provided with an outer guide rail A30 whose inner side surface cooperates with the upper roller and an inner guide rail A40 whose outer side surface cooperates with the lower roller, so that the chain can ensure stable transportation and avoid sagging of the chain and flipping of the egg tray positioning bracket outward.

[0024] In this embodiment, in order to better arrange the outer guide rail and the inner guide rail, the outer side surface of the outer guide rail is connected to one end of an arc-shaped connecting plate A31, and the arc-shaped connecting plate bypasses the bottom surface of the inner guide rail and is fixed to the side guide rail and the other end is connected to the frame, so that the outer guide rail and the inner guide rail are connected to the frame.

[0025] In this embodiment, in order to prevent the chain from turning inward, outer rollers A17 matching the bottom surface of the outer guide rail and inner rollers A18 matching the top surface of the inner guide rail are correspondingly installed on both sides of the chain link for installing the egg tray positioning bracket on the chain mechanism, thereby preventing the chain and the egg tray positioning bracket from turning inward.

[0026] In this embodiment, in order to better install the inner roller and the outer roller, a fixing frame A19 located between a pair of long plate-shaped chain plates is installed on the chain link of the chain mechanism for installing the egg tray positioning bracket, and a horizontal rotating shaft is installed on the fixing frame, and the inner roller and the outer roller are installed at both ends of the horizontal rotating shaft accordingly.

[0027] In this embodiment, the driving mechanism includes a driving sprocket A51 and a driven sprocket A52 arranged on both side ends of the frame. The driving sprocket is driven to rotate by a stepper motor connected to a rotating shaft A53 on the driving sprocket via a reducer. The chain mechanism is wound around the driving sprocket and the driven sprocket. Both the driving sprocket and the driven sprocket are provided with sprocket teeth A54. The ends of the sprocket teeth are provided with positioning recesses A55 that cooperate with the shaft sleeve, thereby better driving the chain to rotate.

[0028] In this embodiment, the distance between the positioning recesses of two adjacent sprocket teeth on the driving sprocket A51 and the driven sprocket A52 is the same as the distance between the shaft sleeves at both ends of the chain link.

[0029] In this embodiment, the egg tray positioning bracket is provided with an "*"-shaped upwardly protruding reinforcing rib portion A22, the positioning boss is truncated cone-shaped and longitudinally arranged side by side on the egg tray positioning bracket, and the egg tray positioning bracket is connected to the fixing frame via a pair of bolts 23 vertically passing through the long plate-shaped chain plate.

[0030] During operation, the active sprocket of the driving mechanism rotates intermittently, so that the chain mechanism drives the egg tray positioning bracket to rotate intermittently on the frame; the egg tray carrying eggs is placed on the egg tray positioning bracket located on the front side from the front side of the frame, and the chain mechanism rotates intermittently, so that the egg tray positioning bracket carrying the egg tray rotates to the rear side, and then the eggs on the egg tray are taken out through the mechanism, and the empty egg tray continues to be transported and removed from the egg tray positioning bracket at the next station.

[0031] like Figures 7 to 12 As shown, in this embodiment, the egg tray stack lifting and conveying device includes a lifting beam G100, and a plurality of egg tray positioning plates G110 arranged in a straight line and rotatable are arranged above the beam G100. The egg tray positioning plates are provided with a limiting groove G111 that cooperates with the bottom of one row of egg slots in the egg tray. The egg tray stack lifting and conveying device of the present invention can simultaneously convey multiple groups of egg tray stacks, and is used for the lifting and conveying of egg tray stacks in the process of destacking egg tray stacks. The orientation of the egg tray positioning plates G110 can be adjusted, and it is convenient, practical, and efficient for egg tray stacks with staggered egg trays.

[0032] The limiting groove G111 of the egg tray positioning plate G110 is formed between a pair of limiting bars. According to the specifications of the egg tray egg slots at the bottom of the egg tray stack, the limiting groove G111 can be set in the middle for odd-numbered rows, and a pair of limiting grooves can be set symmetrically for even-numbered rows.

[0033] In this embodiment, a fixed frame G200 and a lifting transmission mechanism G300 for driving the lifting of the crossbeam are also included; the lifting transmission mechanism G300 includes a swinging beam G310 with one end hinged on the fixed frame and the other end connected to the lower part of the crossbeam G100 through a bracket G320, and the two ends of the bracket are respectively hinged to the other end of the swinging beam and the lower part of the crossbeam; a cam G340 is provided below the swinging beam, and a pressure wheel G311 is rotatably connected to the swinging beam and pressed against the top of the cam. The swinging beam relies on the gravity of the swinging beam itself to make the pressure wheel G311 always press against the top of the cam, and the outer contour of the cam is used to achieve lifting and lowering. The swinging beam rises to drive the crossbeam to lift through the bracket; a seat frame connected to the bracket is provided at the lower part of the crossbeam, and the end of the crossbeam and the bracket are both located in the middle of the seat frame; in order to improve stability, two sets of lifting transmission mechanisms G300 can be set, and the cams of the two sets of lifting transmission mechanisms G300 are installed on the same camshaft; the camshaft is driven by a motor, and the main shaft of the motor is connected to the camshaft through a chain and a sprocket.

[0034] In this embodiment, in order to ensure that there is no angular deflection when the beam is raised or lowered, at least two equal-length and parallel stabilizing bars G330 are provided on the sides of the swing beam G310. One end of the stabilizing bar is hinged to the fixed frame, and the other end is hinged to the beam to form a parallel four-bar structure. The stabilizing bars can be two, three, four, five, or six in number. The parallel four-bar mechanism composed of the stabilizing bars, the fixed frame (fixed) and the beam ensures that the beam can be stably raised or lowered.

[0035] In this embodiment, it also includes a rotating transmission mechanism G400 for driving the egg tray positioning plate to reciprocate by 90°; a rotating shaft G120 rotatably connected to the cross beam is provided at the bottom of the egg tray positioning plate, a swing plate G130 is fixedly connected to the lower part of the rotating shaft, and the swing plates on the rotating shafts of all the egg tray positioning plates are connected together by a linkage connecting rod G140; the rotating transmission mechanism G400 includes a swing rod AG410 located on the side of the swing beam away from the end of the cross beam, the lower end of the swing rod A is hinged on the fixed frame, and a push-pull rod G420 is connected between the upper end of the swing rod A and the swing plate on the rotating shaft of one of the egg tray positioning plates. The swinging action of swing A drives the rotating shaft of the egg tray positioning plate to rotate through the push-pull rod to adjust the orientation of the egg tray positioning plate; the two adjacent layers of the egg tray stack are staggered by 90 degrees, so that the positions of the upper and lower egg slots are staggered, which can ensure the stability of the stacking of the egg trays and reduce the height; therefore, the egg tray positioning plate that can reciprocate by 90 degrees can meet the use requirements of the egg tray stacks with staggered egg trays.

[0036] In this embodiment, a swing member G430 is coaxially hinged to the side of the swing rod A. The swing member G and the swing rod A can be coaxially hinged to the corresponding end of the stabilizing rod. A U-shaped plate G431 is fixedly connected to the swing frame. The swing rod A is located in the middle of the U-shaped plate. Buffer springs G432 are respectively sandwiched between the two side plates of the U-shaped plate and the swing rod A. When the swing member G swings, it drives the swing rod A to swing, and then drives the corresponding egg tray positioning plate to rotate through the push-pull rod. Since the swing plates on the rotating shafts of all egg tray positioning plates are connected by linkage connecting rods, all egg tray positioning plates can achieve synchronous movement. Adding a buffer spring can buffer the movement transmission between the swing member G430 and the swing rod A.

[0037] In this embodiment, the rotary transmission mechanism G400 also includes a turntable G440 coaxially arranged with the cam, a cam groove is arranged on the turntable, a swing rod BG450 is arranged beside the turntable, the lower end of the swing rod B is hinged on the fixed frame, the middle part of the swing rod B is rotatably connected to a roller extending into the cam groove so that when the turntable rotates, the cam groove and the roller cooperate to drive the swing rod B to swing, and a connecting rod G460 is connected between the upper end of the swing rod B and the swinging member. The coaxial arrangement of the turntable and the cam can improve the synchronization of the lifting action and the rotation action of the egg tray positioning plate. Every time the crossbeam is lifted, the egg tray positioning plate rotates 90°.

[0038] In the specific implementation process, the swing rod A can also be provided with a motor to drive the swing through a crank-connecting rod mechanism, and the control system controls the motor to ensure synchronization.

[0039] In this embodiment, the egg tray stacking and displacing mechanism includes a stacking and displacing beam H200 which is controlled to reciprocate by swing arms BH100 at both ends, and a plurality of egg tray clamping mechanisms H300 are arranged below the stacking and displacing beam. Both ends of the stacking and displacing beam H200 are rotatably connected to the upper ends of the two swing arms B, and both ends of the stacking and displacing beam are respectively provided with a stable transmission mechanism H400 for keeping the stacking and displacing beam at a positive working angle (i.e., the egg tray clamping mechanism is always facing downward). The egg tray stacking and displacing mechanism of the present invention can realize the clamping and displacement of the egg trays when the egg trays are displacing through reciprocating motion, and can displacing a plurality of egg trays at the same time, and the displacement stroke is short, and the operation is completed in one step, which is convenient, practical and efficient. In addition, due to the arrangement of the stable transmission mechanism H400, it can be ensured that the destacking beam H200 will not deflect in the process of reciprocating motion with the swing arm B, and always maintains a positive working angle, that is, the egg tray clamping mechanism is always downward, which can ensure that the egg tray is always in a horizontal state during the displacement process, and will not tilt, so as to prevent the egg tray and eggs from falling, and the operation is stable and reliable.

[0040] In this embodiment, the lower end of the swing arm BH 100 is connected to a swing arm connecting shaft BH 500, the stable transmission mechanism includes a first sprocket BH 410 arranged on the swing arm connecting shaft B, a swing shaft H 210 rotatably connected to the upper end of the swing arm B is provided at the end of the destacking beam, and a second sprocket BH 420 is provided on the swing shaft. The first sprocket BH 410 and the second sprocket BH420 are connected by a transmission chain BH 430 so that the destacking beam maintains a positive working angle during the reciprocating motion with the swing arm B. Since the destacking beam H200 and the swing arm BH100 are connected via the swing shaft H210, the destacking beam H200 can rotate relative to the swing arm BH100. Since a plurality of egg tray clamping mechanisms H300 are connected below the destacking beam, the center of gravity of the overall structure of the destacking beam is biased downward, that is, lower than the swing shaft, and the egg tray clamping mechanism H300 can always be in a downward working position. However, in order to prevent the destacking beam H200 from free swinging during the movement, a stable transmission mechanism H400 is added to ensure the stability of the destacking beam H200 during the reciprocating movement, that is, to always maintain a positive working angle.

[0041] In this embodiment, the egg tray clamping mechanism H300 includes a connecting plate H310 connected to the lower side of the stacking beam, and the left egg tray clamping plate 320 and the right egg tray clamping plate H330 that can move synchronously toward or away from each other are hinged on both sides of the connecting plate, and a plurality of egg suction cups H340 are arranged between the left and right egg tray clamping plates; hook plates are arranged at the lower parts of the left and right egg tray clamping plates, which extend to the lower sides of the egg trays during clamping to prevent the egg trays from falling; and a plurality of egg suction cups H340 are added in the middle, which can suck part of the eggs in the process of grabbing the egg trays, thereby reducing the weight borne by the egg tray clamping plates on both sides.

[0042] In this embodiment, a suction cup connection plate is connected to the bottom of the connection plate H310 by bolts, and a plurality of air distribution pipes are connected to the bottom of the suction cup connection plate. The egg suction cups H340 are distributed in an array, and the egg suction cups H340 in the same row are connected to the same air distribution pipe.

[0043] In this embodiment, the stacking removal beam H200 is provided with a push-pull plate H220 that can slide left and right relative to the stacking removal beam H200 and a cylinder BH230 for driving the push-pull plate to reciprocate. One end of the cylinder BH230 is hinged to the stacking removal beam H200 and the other end is hinged to the push-pull plate H220. The hinged portion of the right egg tray clamping plate H330 is provided with an extension plate H331 extending upward. A connecting rod BH240 is connected between the extension plate and the push-pull plate, and a linkage rod H350 is connected between the extension plate and the left egg tray clamping plate. When the cylinder BH230 drives the push-pull plate H220 to slide left and right, the push-pull plate H220 drives the right egg tray clamping plate H330 to swing through the connecting rod BH240, and the right egg tray clamping plate H330 drives the left egg tray clamping plate to move synchronously through the linkage rod H350. In the specific implementation process, the connection mode of the left and right egg tray clamping plates can also be exchanged and belong to the same structure.

[0044] In this embodiment, the push-pull plate is provided with a plurality of horizontal guide grooves, and pins connected to the destacking beam H200 are provided in the horizontal guide grooves, so as to guide the push-pull plate and enable it to slide stably.

[0045] In this embodiment, in order to increase the buffer function of the entire egg tray clamping mechanism H300, the upper end of the connecting plate H310 is fixedly connected to a connecting shaft H360 that passes through the stacking beam upward and can slide up and down relative to it, and the upper end of the connecting shaft is fixedly connected to a baffle H361 that is stuck on the upper side of the stacking beam, and a spring H370 is connected between the baffle H361 and the stacking beam.

[0046] like Figures 17 to 21As shown, the egg tray egg taking device includes an egg taking frame F1, and a swing arm mechanism F2 is connected to the egg taking frame for symmetrical rotation, and an egg taking mechanism F3 is installed between the swing arm ends of the two swing arm mechanisms. A cam mechanism F4 for driving the swing arm mechanism to swing is installed under the two swing arm mechanisms on the egg taking frame. Specifically, a conveyor belt F26 is arranged on the front side of the egg taking frame for conveying egg trays containing eggs, and at the same time, the input end of the next process equipment is arranged on the other side of the conveyor belt corresponding to the egg taking mechanism. Manually, only the egg tray needs to be placed on the conveyor belt, and the egg tray containing eggs is conveyed to between the input end of the subsequent grading and classification equipment and the device through the conveyor belt. Then, through the reciprocating swinging motion of the swing arm mechanism, the egg taking mechanism is driven to reciprocate between the input end of the subsequent grading and classification equipment and the conveyor belt, so that the egg taking mechanism can transfer the eggs to the subsequent grading and classification equipment after sucking the eggs, which is convenient for professional egg production, improves production efficiency, and reduces manpower.

[0047] In this embodiment, the swing arm mechanism includes a swing arm F5, one end of which is rotatably connected to the egg retrieval frame, and the other end is hinged with an egg retrieval mechanism mounting arm F6. The egg retrieval mechanism is installed between the suspended ends of the two egg retrieval mechanism mounting arms. When in use, the egg retrieval mechanism can reciprocate between the conveyor belt and the next process equipment by driving the swing arm and the egg retrieval mechanism mounting arm. The rotational connection method in this device can be an existing rotating shaft type, as long as rotation can be achieved.

[0048] In this embodiment, in order to achieve smooth movement of the egg taking mechanism, the egg taking mechanism mounting arm includes two mounting links F7 arranged in parallel front and back, the upper ends of the two mounting links are hinged on the swing arm, and the lower ends of the two mounting links are hinged on a mounting fixing rod F8. The spacing between the upper end hinge points of the two mounting links is equal to the spacing between the lower end hinge points of the two mounting links, that is, the two mounting links, the mounting fixing rod, and the swing arm section between the upper end hinge points of the two mounting links constitute a parallelogram linkage. The egg taking mechanism is installed between the mounting fixing rods of the two egg taking mechanism mounting arms. Since the two ends of the egg taking mechanism move through the parallelogram linkage, the plane where the egg taking mechanism is located is the plane determined by the two mounting fixing rods. Therefore, the egg taking surface position and the egg placing surface position of the egg taking mechanism can be effectively controlled, which is convenient for equipment operation.

[0049] In this embodiment, in order to ensure the smooth operation of the swing arm, the swing arm includes an auxiliary swing arm F9 and a main swing arm F10 which are arranged in parallel up and down. The rear ends of the main swing arm and the auxiliary swing arm are both rotatably connected to the egg retrieval frame. The front ends of the main swing arm and the auxiliary swing arm are both hinged in an L-shaped bracket F11.
