[0016] Another technical solution adopted by the present invention is: a working method of a seed egg tray loading machine, the working method comprising the following steps:

[0017] Step S1, weighing the eggs:

[0018] Step S11: the egg input roller group conveys the breeding eggs to be weighed. When the breeding eggs to be weighed on the egg input roller group fall on the input track, one of the conveying rollers holds the breeding eggs to be weighed, so that the breeding eggs to be weighed slowly move downward along the input track;

[0019] Step S12: When the breeding eggs to be weighed fall on the weighing sensor and remain stationary, the conveying roller is separated from the breeding eggs to be weighed, and the weighing sensor weighs the breeding eggs. If the weight of the breeding eggs falls within the set weight range, they are qualified breed eggs; if the weight of the breeding eggs is greater than the set weight range, they are oversized breeding eggs; if the weight of the breeding eggs is less than the set weight range, they are undersized breeding eggs;

[0020] Step S13: After weighing, the next conveyor roller pushes the weighed eggs to start moving along the output track;

[0021] Step S2, output of weighed eggs:

[0022] Step S21: If the eggs moving along the output track are of qualified varieties, the conveying roller pushes the qualified varieties of eggs to move from the opening of the openable and closable guide plate to the first egg output belt;

[0023] Step S22: If the eggs moving along the output track are oversized eggs, the guide cylinder drives the movable guide plate to move upward to the upper end and connect with the lower end of the fixed guide plate, and the output roller drives the oversized eggs to move along the movable guide plate and the fixed guide plate. When the oversized eggs move to the upper end of the fixed guide plate, the two front egg paddles on the left and right sides above the fixed guide plate move the oversized eggs forward from bottom to top, so that the oversized eggs fall on the second egg output belt;

[0024] Step S23: If the eggs moving along the output track are super small eggs, the guide cylinder drives the movable guide plate to move upward to the upper end and connect with the lower end of the fixed guide plate, and the output roller drives the super small eggs to move along the movable guide plate and the fixed guide plate. When the super large eggs move to the upper end of the fixed guide plate, the cylinder rod of the egg pushing cylinder contracts forward, driving the upper end of the egg pushing plate to rotate backward, and the egg pushing plate pushes the eggs backward, so that the eggs pass over the conveying roller, and the rear egg paddle pushes the super small eggs backward from bottom to top, so that the super small eggs fall on the third egg output belt;

[0025] Step S3, sorting qualified eggs:

[0026] Step S31: the disordered qualified eggs are neatly put into the egg inlet channel, and then put into the surface of the drum in order from the egg inlet channel. As the drum rotates, the eggs continue to be transported;

[0027] Step S32: During the rotation of the rollers, the qualified eggs will deviate to the side of the small heads of the eggs on the rollers until they hit the positioning plate and stop. When the qualified eggs are transported to between the last two groups of rollers, the push rod at the center of the rollers is pushed upward, and the rotating paddles assist in moving the small heads of the qualified eggs to the side of the egg tray, and cooperate with the egg output roller group to transport the eggs to the side of the egg tray, so that the small heads of the qualified eggs falling into the egg tray face downward.

[0028] Step S33: as the distance between the two baffles changes, the egg trays on the conveying shaft are guided to move closer in sequence until the multiple egg trays are neatly and closely arranged;

[0029] Step S34: the driving motor rotates forward, driving the swing arm to move toward the upper side of the egg tray conveying mechanism, and when the suction cup moves to the upper side of the qualified eggs and contacts the qualified eggs in sequence, the suction cup absorbs the qualified eggs;

[0030] Step S35: the driving motor is reversed, and the swing drives the egg sucking rack to swing to the other side, and the qualified eggs are aligned with the holes in the egg tray, and the suction cup is deflated and the qualified eggs are placed in the empty space in the egg tray; during the swinging process, the suction port of the suction cup is always facing downward;

[0031] Step S4: Repeat steps S1 to S3.

[0053] In this embodiment, the weighing assembly 2 includes a plurality of weighing sensors 5 arranged side by side in the longitudinal direction. The weighing sensors 5 are mounted on a sensor bracket. The rear side of each weighing sensor 5 is provided with an input track 6 for facilitating the rolling of the eggs from top to bottom. The front side of each weighing sensor 5 is provided with an output track 7 for facilitating the rolling of the weighed eggs from bottom to top. The weighing assembly 2 is located below the egg input roller group 1 and the first egg output belt 3. The input track 6 is an inclined device with a high rear end and a low front end. The eggs transported from the egg input roller group 1 fall on the input track 6. The eggs 30 roll down along the input track 6 under the action of gravity. The output track 7 includes a horizontal section and an inclined section with a low rear end and a high front end. It should be noted that the top surfaces of the input track 6 and the output track 7 are in contact with the eggs. Preferably, the input track and the output track are both composed of two parallel flat plates.

[0054] In this embodiment, the annular conveying roller group 8 includes two annular chains 11 arranged on the left and right sides of the weighing assembly 2, the two annular chains 11 are driven to rotate via a power mechanism, a plurality of conveying rollers 12 are fixedly connected between the two annular chains 11, and the annular chains 11 drive the plurality of conveying rollers 12 to perform annular circulation conveying; when the breeding eggs to be weighed transported from the egg input roller group 1 fall on the input track 6, one of the conveying rollers 12 holds the breeding eggs to be weighed, and since the conveying roller 12 keeps moving all the time, the conveying roller 12 holds the breeding eggs to be weighed and slowly moves downward along the input track 6; when the breeding eggs to be weighed are transported from the egg input roller group 1 to the input track 6, the conveying roller 12 holds the breeding eggs to be weighed and slowly moves downward along the input track 6; When the weighed eggs are about to approach the weighing sensor 5, since the conveying roller 12 is located in front of the eggs to be weighed, the conveying roller 12 will first push the weighed eggs on the weighing sensor 5 toward the output track 7, so that the eggs to be weighed fall on the weighing sensor 5; when the eggs to be weighed fall on the weighing sensor 5 and remain stationary, the conveying roller 12 separates from the eggs to be weighed, and the conveying roller 12 pushes the weighed eggs to start moving along the output track 7. The weighed eggs first move along the horizontal section of the output track 7, then move along the inclined section, and finally move to the egg output belt 3. Preferably, the conveying roller is a bare rod.

[0055] In this embodiment, there are multiple openable and closable material guide plates 31, and the multiple openable and closable material guide plates 31 correspond to the positions of the multiple weighing sensors 5 one by one. The openable and closable material guide plates 31 include a movable material guide plate 15 obliquely arranged inside the output track and a fixed material guide plate 34 obliquely arranged above the movable material guide plate 15. There is an opening between the fixed material guide plate 34 and the movable material guide plate 15 to facilitate the passage of the breeding eggs and convey them to the first egg output belt 3. The movable material guide plate 15 is driven by the guide cylinder 16 located below it to move upward to the upper end and connect with the lower end of the fixed material guide plate 34, so that the annular conveying roller group 8 pushes the breeding eggs to move upward to close to the second egg output belt 13 and the third egg output belt 14. When the weight of the egg scale exceeds the set weight range, the guide cylinder 16 drives the movable guide plate 15 to move upward to the upper end and connect with the lower end of the fixed guide plate 34, so that the conveying roller 12 pushes the unqualified eggs to move upward along the output track 7, the movable guide plate 15 and the movable guide plate 34 in sequence. Preferably, the rear end of the movable guide plate is V-shaped.

[0056] In this embodiment, the front egg-moving group 32 includes a front rotating shaft 35 which is longitudinally arranged and driven to rotate by a front driving motor, and a triangular front egg-moving paddle 36 is fixedly connected to the front rotating shaft 35 on the left and right sides of each fixed guide plate, and the front side of each fixed guide plate 34 is provided with an egg-pushing assembly for pushing the breeding eggs moved to the upper end of the fixed guide plate 34 backward; the rear egg-moving assembly 33 includes a rear rotating shaft 37 which is longitudinally arranged and driven to rotate by a rear driving motor, and a plurality of rear egg-moving paddles 38 are fixedly connected to the rear rotating shaft 37, and the rear egg-moving paddles 38 correspond to the position of the fixed guide plate 34 and are used to move the breeding eggs pushed by the pushing assembly backward to the third egg output belt 14. Since the position of the rear egg paddle 38 corresponds to that of the fixed guide plate 34, that is, the position of the rear egg paddle 38 is misaligned with that of the front egg paddle 36, when an oversized egg is moved along the fixed guide plate 34, the two front egg paddles 36 on the left and right sides above the fixed guide plate 34 push the oversized egg forward from bottom to top, so that the oversized egg falls on the second egg output belt 13; when an oversized egg is moved along the fixed guide plate 34, when the oversized egg moves to the upper end of the fixed guide plate 34, the egg pushing assembly pushes the downward egg backward, so that the oversized egg passes over the conveying roller 12 backward, and then the rear egg paddle 38 pushes the oversized egg backward from bottom to top, so that the oversized egg falls on the third egg output belt 14.

[0057] In this embodiment, each of the fixed material guide plates 34 is fixedly connected with a guard plate 39 on both sides; the egg pushing assembly includes an egg pushing plate 40 and an egg pushing cylinder 41 located in front of the egg pushing plate 40, the middle of the egg pushing plate 40 is hinged with one of the guard plates 39, the upper end of the egg pushing plate 40 extends to the top of the fixed material guide plate 34, and the cylinder rod of the egg pushing cylinder 41 extends backward and is hinged with the lower end of the egg pushing plate 40 to drive the egg pushing plate 40 to rotate.

[0061] In this embodiment, baffles 25 are provided on both sides of the front end of the entire conveying mechanism 10, and the spacing between the two baffles 25 decreases successively along the conveying direction of the breeding eggs and then remains unchanged; as the spacing between the two baffles 25 changes, the egg trays 21 on the conveying shaft 20 are guided to approach one by one until multiple egg trays 21 are neatly and closely arranged.

[0062] In this embodiment, a rotating shaft 22 is provided between the output end of the egg output roller group 9 and the input end of the entire array conveying mechanism 10. The rotating shaft 22 is provided with a plurality of paddles 23 at intervals along its axial direction, and a channel is formed between adjacent paddles 23. When the eggs are lifted by the push rod 19, the rotating paddles 23 push the small end of the eggs to one side of the egg tray 21, thereby assisting the eggs to fall into the egg tray 21. The rotating shaft 22 can be driven to rotate by a motor or other driving device.

[0063] In this embodiment, positioning plates 24 are provided on both sides of the drum 18. The diameter of the positioning plates 24 is larger than the diameter of the drum 18 to prevent the eggs from falling. A space is formed between the drum 18 and the positioning plates 24 to allow the eggs to be axially offset. The push rod 19 can be driven to rise or fall by a driving mechanism.

[0064] In this embodiment, an egg inlet guide mechanism 26 is provided at the rear side of the egg output roller group 9 (i.e., above the front end of the first egg output belt). The egg inlet guide mechanism 26 is composed of a fixed frame 27 and guide plates 28 located below the fixed frame 7 and arranged at intervals. An egg inlet channel 29 is formed between adjacent guide plates 28, and the egg inlet channel 29 corresponds to the roller 18 one by one.

[0065] In this embodiment, the egg suction conveying mechanism 44 includes an egg suction rack 45 and a plurality of suction cups 46 evenly distributed below the egg suction rack. A swing arm 47 swinging along the lower end of the swing arm is provided on the side of the egg tray conveying mechanism, and the upper end of the swing arm is connected to the top of the egg suction rack.

[0066] In this embodiment, an arc-shaped guide plate 49 is provided at the rear of the swing arm, and a guide groove 48 slidably matched with the edge of the arc-shaped guide plate is provided at the upper rear of the swing arm; a driving motor 50 for driving the swing arm to swing is provided at the rear of the arc-shaped guide plate.

[0067] In this embodiment, a vacuum pump 51 is provided outside the suction cup, and the vacuum pump is connected to the suction cup via a pipeline 52.

[0068] In this embodiment, a connecting shaft 53 is provided between the swing arm and the egg sucking frame.

[0069] When it is necessary to transport qualified eggs in an orderly manner: the disordered qualified eggs enter the egg-entry channel in order, and then enter the surface of the drum from the egg-entry channel in order. As the drum rotates, the qualified eggs continue to be transported. During the rotation of the drum, the qualified eggs will deviate to the side of the small end of the egg on the drum until they hit the positioning plate and stop (the center of the drum is on the side biased to the large end). When the qualified eggs are transported between the last two groups of rollers, the push rod at the center of the drum pushes up, that is, the large end side of the qualified eggs is pushed up, and the eggs are tilted toward the small end. At the same time, the rotating paddle assists in moving the qualified eggs to the small end. The small end of the breeding egg is moved to one side of the egg tray, and is transported to the side of the egg tray in cooperation with the roller transmission mechanism, so that the small end of the eggs dropped into the egg tray faces downward. When the qualified eggs are neatly arranged in the egg tray, the vacuum pump is started, and the drive motor rotates forward, driving the swing arm to move toward the top of the egg tray conveying mechanism. When the suction cup moves above the eggs and contacts the eggs in turn, the vacuum pump is started to absorb the qualified eggs, and the drive motor reverses, swinging to drive the egg suction rack to swing to the other side, and aligning the eggs with the holes in the egg tray, the vacuum pump deflates and places the qualified eggs in the egg tray; during the swinging process, the suction mouth of the suction cup is always facing downward.

[0070] In this embodiment, the egg tray conveying mechanism includes a positioning cavity 54 for stacking egg trays 69 in sequence from top to bottom, an egg tray belt conveying mechanism 55 is arranged at the bottom of the positioning cavity, a pair of guide rods 56 are symmetrically arranged on both sides of the positioning cavity, each guide rod is provided with a top block 57, an arc-shaped card plate 58 for clamping the egg tray is arranged above the top block, a plurality of guide inclined grooves 59 are symmetrically arranged on the outside of the positioning cavity, a guide shaft 60 moving along the guide inclined groove is provided in the guide inclined groove, and the outer side of the arc-shaped card plate is fixedly connected to the inner side of the guide shaft; the top block pushes up to lift the arc-shaped card plate, and the arc-shaped card plate moves obliquely along the length direction of the guide inclined groove with the guide shaft, and the arc-shaped card plate is separated from the egg tray, so that the lowest egg tray is output by the belt conveying mechanism, and the second to last egg tray drops to the lowest position.

[0071] In this embodiment, frames 62 are provided on both sides of the positioning cavity, and brackets 61 are horizontally provided between the upper parts of the front and rear of the two frames. Four groups of guide bevel grooves can be symmetrically provided on the front and rear of the frames, and a guide shaft passes through each group of guide bevel grooves from front to back. Positioning nuts 63 are provided at both ends of the guide shaft, and a reset spring 63 is provided between the positioning nut and the end of the bracket; when the guide shaft is lifted upward by the top block, the spring is stretched; when the top block descends, the spring releases the elastic potential energy, so that the rotating shaft and the arc-shaped clamping plate can be reset faster.

[0072] In this embodiment, the positioning cavity is composed of four vertically arranged limit rods 65, the cross-section of the limit rod is "L"-shaped, the lower end of the limit rod does not exceed the height position of the bracket, the limit rod is fixed on the frame and there is a spacing between the lower end of the limit rod and the belt transmission mechanism, and the spacing is at least the height of an egg tray, so that the lowest egg tray can pass smoothly and avoid obstruction.

[0073] In this embodiment, a connecting rod 66 is hinged on the outer side of the top block, and a short rod 67 is hinged below the connecting rod. The short rod is driven to rotate by a motor 68, and the motor output shaft is fixed to the short rod. The motor drives the short rod to rotate, pulling the connecting rod up and down, thereby causing the top block to move up and down along the guide rod.

[0074] In this embodiment, the guide chute is inclined, and the angle between the guide chute and the horizontal line can be 30°~60°.

[0075] When the egg tray conveying mechanism is working: the whole row of egg trays are placed in the positioning cavity, the egg tray at the bottom is output by the belt conveyor mechanism, the motor drives the top block to rise, and the arc-shaped pallet is lifted up. The arc-shaped pallet and the guide shaft are subjected to an upward force and move along the length direction of the guide inclined groove. The arc-shaped pallet is separated from the second to last egg tray at the bottom, and the second to last egg tray at the bottom falls to the bottom, that is, to the belt conveyor mechanism, the motor drives the top block to fall, the arc-shaped pallet and the guide shaft are reset, and the egg tray located above the bottom egg tray is repositioned to hook the egg tray, so that the bottom egg tray can be output by the belt conveyor mechanism, and so on.

[0076] The specific implementation process includes the following steps:

[0077] Step S1, weighing the eggs:

[0078] Step S11: the egg input roller group 1 conveys the breeding eggs 30 to be weighed. When the breeding eggs to be weighed on the egg input roller group 1 fall on the input track 6, one of the conveying rollers 12 holds the breeding eggs to be weighed. Since the conveying roller 12 keeps moving all the time, the conveying roller 12 holds the breeding eggs to be weighed and slowly moves downward along the input track 6;

[0079] Step S12: When the breeding eggs to be weighed fall on the weighing sensor and remain stationary, the conveying roller is separated from the breeding eggs to be weighed, and the weighing sensor weighs the breeding eggs. If the weight of the breeding eggs falls within the set weight range, they are qualified breed eggs; if the weight of the breeding eggs is greater than the set weight range, they are oversized breeding eggs; if the weight of the breeding eggs is less than the set weight range, they are undersized breeding eggs;

[0080] Step S13: After weighing, the next conveyor roller pushes the weighed eggs to start moving along the output track;

[0081] Step S2, output of weighed eggs:

[0082] Step S21: if the eggs moving along the output track are qualified eggs, the conveying roller pushes the qualified eggs from the opening of the closable guide plate to the first egg output belt, and the eggs are transported by the first egg output belt 3;

[0083] Step S22: If the eggs moving along the output track are oversized eggs, the guide cylinder drives the movable guide plate to move upward to the upper end and connect with the lower end of the fixed guide plate, and the output roller drives the oversized eggs to move along the movable guide plate and the fixed guide plate. When the oversized eggs move to the upper end of the fixed guide plate, the two front egg paddles on the left and right sides above the fixed guide plate move the oversized eggs forward from bottom to top, so that the oversized eggs fall on the second egg output belt;

[0084] Step S23: If the eggs moving along the output track are super small eggs, the guide cylinder drives the movable guide plate to move upward to the upper end and connect with the lower end of the fixed guide plate, and the output roller drives the super small eggs to move along the movable guide plate and the fixed guide plate. When the super large eggs move to the upper end of the fixed guide plate, the cylinder rod of the egg pushing cylinder contracts forward, driving the upper end of the egg pushing plate to rotate backward, and the egg pushing plate pushes the eggs backward, so that the eggs pass over the conveying roller, and the rear egg paddle pushes the super small eggs backward from bottom to top, so that the super small eggs fall on the third egg output belt;

[0085] Step S3, sorting qualified eggs:

[0086] Step S31: In step S21, the disordered qualified eggs are neatly put into the egg inlet channel, and then put into the surface of the drum from the egg inlet channel. As the drum rotates, the eggs continue to be transported;

[0087] Step S32: During the rotation of the rollers, the qualified eggs will deviate to the side of the small heads of the eggs on the rollers until they hit the positioning plate and stop. When the qualified eggs are transported to between the last two groups of rollers, the push rod at the center of the rollers is pushed upward, and the rotating paddles assist in moving the small heads of the qualified eggs to the side of the egg tray, and cooperate with the egg output roller group to transport the eggs to the side of the egg tray, so that the small heads of the qualified eggs falling into the egg tray face downward.

[0088] Step S33: as the distance between the two baffles changes, the egg trays on the conveying shaft are guided to move closer in sequence until the multiple egg trays are neatly and closely arranged;

[0089] Step S34: the driving motor rotates forward, driving the swing arm to move toward the upper side of the egg tray conveying mechanism, and when the suction cup moves to the upper side of the qualified eggs and contacts the qualified eggs in sequence, the suction cup absorbs the qualified eggs;

[0090] Step S35: the driving motor is reversed, and the swing drives the egg sucking rack to swing to the other side, and the eggs are aligned with the holes in the egg tray, the suction cup is deflated and the qualified eggs are placed in the empty space in the egg tray; during the swinging process, the suction port of the suction cup is always facing downward;

[0091] Step S4: Repeat steps S1 to S3.

[0092] If the present invention discloses or involves components or structures that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by integrated molding using a casting process) (except when it is obviously impossible to use an integrated molding process).

[0093] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in the present invention include states or shapes that are approximate, similar, or close to them.

[0094] Any component provided by the present invention may be assembled from a plurality of separate components, or may be a separate component manufactured by an integral forming process.
