[0043] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0044] The present embodiment relates to a supporting device, which overall comprises a frame 1, a plurality of first guide rails 2 and a plurality of second guide rails 3 arranged on the frame 1 for sliding along a first direction and a second direction respectively, a plurality of egg trays 4 which are simultaneously connected to a first guide rail 2 and a second guide rail 3 via a transmission member 401, and a first transmission part and a second transmission part arranged on the frame 1, wherein the first transmission part is connected to each of the first guide rails 2, and the second transmission part is connected to each of the second guide rails 3.

[0045] Among them, the first direction is perpendicular to the second direction, the first transmission part is driven to swing relative to the frame 1, and drives each first guide rail 2 to slide along the first direction, and under the transmission of the transmission member 401 and the second transmission part, it can drive each second guide rail 3 to slide along the second direction to adjust the distance between two adjacent egg trays 4.

[0046] The supporting device described in this embodiment enables the first transmission part to be driven to swing relative to the frame 1 to drive each of the first guide rails 2 to slide along the first direction, and under the transmission of the transmission member 401 and the second transmission part, drives each of the second guide rails 3 to slide along the second direction, so as to adjust the distance between two adjacent egg trays 4 in the first direction and the second direction. Compared with the manual adjustment method, it has higher operational convenience and adjustment efficiency. Compared with the traditional automatic adjustment method, it can reduce the space occupied, thereby helping to improve the use effect of the supporting device.

[0047] Based on the above overall introduction, the supporting device in this embodiment has a first state in which multiple egg trays 4 are closely arranged together, and a second state in which multiple egg trays 4 are separated. The structure of the supporting device in the first state is as follows: Figure 1 and Figure 3 As shown in , the structure in the second state is as follows Figure 2 and Figure 4 as shown in .

[0048] The frame 1 is used as a carrier of the entire supporting device, and it has an upper frame 101 and a lower frame 102 spaced apart from each other, and each frame is rectangular. The frame 1 also includes a plurality of columns 103 connected to the four corners of the upper frame 101 and the lower frame 102 and extending downward. The structure of the frame 1 is simple and easy to arrange and implement. Of course, each frame can also be in other geometric shapes such as a square. In order to facilitate the movement of the device, handles 105 are respectively provided on two opposite sides of the lower frame 102.

[0049] In the specific implementation, in order to facilitate the adjustment of the rack 1, an adjustment foot 104 can be provided at the bottom of each column 103. The adjustment foot 104 can adopt a product in the prior art, which is a support component with an adjustment function. Through its internal threaded rod, adjustment pad and other structures, the height and levelness of the rack 1 can be adjusted. Of course, the adjustment foot 104 can also be omitted according to the use requirements.

[0050] The first direction in this embodiment may be the length direction or the width direction of the rack 1. A plurality of first guide rails 2 extend along the second direction and are slidably disposed at the bottom of the upper frame 101 along the first direction. A plurality of second guide rails 3 extend along the first direction and are slidably disposed at the top of the lower frame 102 along the second direction. The plurality of first guide rails 2 and the plurality of second guide rails 3 are disposed on the rack 1 at intervals and orthogonal to each other.

[0051] In terms of specific structure, Figure 7As shown in , in order to facilitate the sliding of each first guide rail 2 on the upper frame 101, first slide grooves 301 extending along the first direction are respectively provided on both sides of the upper frame 101 corresponding to the two ends of each first guide rail 2, and first sliders 203 are respectively provided at the two ends of each first guide rail 2. By sliding the first sliders 203 in the corresponding first slide grooves 301, each first guide rail 2 can slide on the frame 1 along the first direction.

[0052] Correspondingly, corresponding to the two ends of each second guide rail 3, second slide grooves 302 extending along the second direction are respectively provided on both sides of the lower frame 102, and second sliders 303 are respectively provided at the two ends of each second guide rail 3. By sliding the second sliders 303 in the corresponding second slide grooves 302, each second guide rail 3 can slide on the frame 1 along the second direction.

[0053] The structure of the egg tray 4 in this embodiment is as follows Figure 8 and Fig. 9 As shown in the figure, the egg tray 4 has a cavity with an opening facing upward, and the poultry egg 100 is specifically placed in the cavity. In order to improve the placement stability of the poultry egg 100 in the egg tray 4, a plurality of protrusions 402 protruding upward and arranged at intervals along the circumference of the opening can also be provided on the egg tray 4. The egg tray 4 abuts against the outer periphery of the poultry egg 100 through the plurality of protrusions 402, which is conducive to limiting the movement of the poultry egg 100 in the radial direction of the egg tray 4, thereby having good supporting stability, and the structure of the protrusions 402 is simple and easy to process and shape. Of course, the structure of the egg tray 4 can still be adjusted according to the use requirements during specific implementation.

[0054] As a preferred embodiment, still refer to Figure 8 As shown in , the transmission member 401 in this embodiment includes a transmission rod disposed at the bottom of the egg tray 4, and the transmission rod is inserted into the vertically disposed first guide rail 2 and second guide rail 3. The upper and lower ends of the transmission rod are provided with first bearings 403, and the first bearings 403 at both ends abut against the end surfaces of the first guide rail 2 and the second guide rail 3 respectively. The structure of the transmission rod here is simple, and the first bearing 403 is conducive to improving the smoothness of the transmission rod in sliding. In addition, a second bearing located between the two first bearings 403 can also be provided on the transmission rod to further improve the sliding smoothness of the transmission rod.

[0055] In specific implementation, the first bearing 403 can be an end bearing in the prior art, which uses the rolling characteristics of balls or rollers to bear the load, can quickly transfer force when rolling, and has less friction and wear. The contact surfaces between the inner and outer rings of the end bearing and the balls are lubricated with lubricants. When the bearing bears the load, the lubricant forms a film, further reducing friction and wear. The second bearing can be an axial bearing in the prior art, which can bear the axial force of the transmission rod, effectively reducing the friction and wear of the transmission rod, thereby extending the service life of the transmission rod.

[0056] As a preferred arrangement, Figure 8 As shown in , the second guide rail 3 is provided with a first chute 301 and a second chute 302 spaced apart along the second direction, and the first chute 301 and the second chute 302 both extend along the first direction. The egg trays 4 located on the same first guide rail 2 are all arranged in the first chute 301 or the second chute 302 of each second guide rail 3 through the corresponding transmission member 401, and the egg trays 4 on multiple first guide rails 2 are alternately arranged in the first chute 301 and the second chute 302 through the transmission member 401. Here, the arrangement of the first chute 301 and the second chute 302 enables one second guide rail 3 to adjust two rows of egg trays 4, thereby improving the adjustment efficiency and facilitating the arrangement and implementation.

[0057] In terms of specific structure, Figure 7 and Figure 8 As shown in the figure, the first guide rail 2 is provided with a third slide groove 201 extending along the second direction, each transmission rod is inserted into the third slide groove 201 and the first slide groove 301, or is inserted into the third slide groove 201 and the second slide groove 302, and the egg tray 4 can slide in the third slide groove 201 along the second direction, thereby changing the distance between two adjacent egg trays 4 in the second direction.

[0058] As a preferred example, Figure 3 and Figure 4 As shown in the figure, in the two rows of egg trays 4 on the two adjacent first guide rails 2, the transmission rods of one row of multiple egg trays 4 are inserted into the third slide groove 201 and the first slide groove 301, and the transmission rods of the other row of multiple egg trays 4 are inserted into the third slide groove 201 and the second slide groove 302, so that the multiple egg trays 4 on the two adjacent first guide rails 2 are alternately arranged in the second direction, thereby facilitating the compactness of the device in the first state and facilitating the optimal utilization of the space on the frame 1.

[0059] As a preferred embodiment, Figure 3 and Figure 4 As shown in , the first transmission part in this embodiment includes a first transmission plate 5 extending along the first direction, and one end of the first transmission plate 5 is rotatably arranged on the frame 1. The first transmission plate 5 is provided with first guide grooves 501 corresponding to the plurality of first guide rails 2 one by one, and the first transmission plate 5 guides the corresponding first guide rails 2 to slide along the first direction through the first guide grooves 501. Here, the structures of the first transmission plate 5 and the first guide grooves 501 are simple, easy to arrange and implement, and the positions of the plurality of first guide rails 2 can be adjusted by operating the first transmission plate 5 to rotate, which has good operational convenience.

[0060] In this embodiment, the end of each first guide rail 2 is provided with a transmission shaft 202 inserted in the first guide groove 501. When the first transmission plate 5 rotates, the transmission of the first transmission plate 5 and the first guide rail 2 can be realized through the cooperation of the first guide groove 501 and the transmission shaft 202, thereby driving each first guide rail 2 to slide along the first direction.

[0061] like Figure 3 and Figure 4 As shown in , each first guide groove 501 is an inclined groove set at an angle with the first direction, and the angle between the multiple first guide grooves 501 and the first direction gradually decreases along the direction away from the swing center of the first transmission plate 5. Here, the angle between the multiple first guide grooves 501 and the first direction gradually decreases, which is conducive to adjusting the spacing between two adjacent egg trays 4 in the first direction to be roughly the same. In addition, along the direction away from the swing center of the first transmission plate 5, the length of the multiple first guide grooves 501 gradually increases, which is conducive to meeting the requirements of different sliding distances of different first guide rails 2 in the first direction, and further helps to ensure that the spacing between two adjacent first guide rails 2 is roughly equal in the second state.

[0062] As a preferred example, Figure 3 As shown in the figure, in this embodiment, two first transmission plates 5 are arranged on two opposite sides of the frame 1, and an operating rod 502 is connected between the two first transmission plates 5. The two ends of the first guide rail 2 are respectively inserted into the first guide groove 501 on the corresponding side through the transmission shaft 202, and an operating rod 502 is connected between the free ends of the two first transmission plates 5. Here, by applying a force to the operating rod 502, the two first transmission plates 5 can be driven to rotate synchronously, thereby facilitating the stability and operational convenience of adjusting the spacing of the egg trays 4.

[0063] When the plurality of first guide rails 2 are in the first state, Figure 3 As shown in , each transmission shaft 202 is located at the bottom end of each corresponding first guide groove 501, and the distance between two adjacent transmission shafts 202 is the smallest, and the distance between two adjacent first guide rails 2 in the first direction is the smallest. When the plurality of second guide rails 3 are in the second state, as shown in Figure 4 As shown in , as the first transmission plate 5 rotates downward, each transmission shaft 202 slides in the corresponding first guide groove 501 until each transmission shaft 202 is displaced to the top of the corresponding first guide groove 501. At this time, the distance between two adjacent transmission shafts 202 is the largest, that is, the distance between two adjacent first guide rails 2 in the first direction is the largest.

[0064] As a preferred embodiment, Figure 5 and Figure 6As shown in , the second guide rails 3 are all arranged below the first guide rails 2, and the second transmission part includes a second transmission plate 6 arranged below the second guide rails 3. A plurality of second guide grooves 601 are arranged on the second transmission plate 6, and the plurality of second guide grooves 601 are arranged one-to-one with the first slide grooves 301 or the second slide grooves 302 of the second guide rails 3, and one of the transmission members 401 located on each second guide rail 3 is arranged in the second guide groove 601. Here, by setting the transmission member 401 in the second guide groove 601, the second guide groove 601 can guide the transmission member 401, so as to facilitate the adjustment of the spacing between two adjacent egg trays 4 in the second direction.

[0065] Specifically, each second guide groove 601 is an inclined groove arranged at an angle to the second direction, and the angles between the plurality of second guide grooves 601 and the second direction gradually decrease. With such arrangement, the sliding distance of each second guide rail 3 can be adjusted according to the position of different second guide rails 3, so that the spacing between two adjacent egg trays 4 in the second direction is adjusted to be substantially the same.

[0066] As an example of a structure Figure 5 Taking the angle of view shown as a reference, the angles between the plurality of second guide grooves 601 and the second direction are gradually reduced from top to bottom, and when the transmission rod slides from the right end to the left end of the second guide groove 601, the spacing between the plurality of second guide rails 3 gradually decreases until they are gathered together. When the transmission rod slides from the left end to the right end of the second guide groove 601, the spacing between the plurality of second guide rails 3 gradually increases until they are separated.

[0067] In specific implementation, multiple transmission rods located in the same first slide groove 301 or second slide groove 302 are all arranged in the second guide groove 601. At this time, the first bearing 403 corresponding to the bottom of the transmission rod is located at the bottom of the second transmission plate 6 to ensure the sliding effect of the transmission rod in the second guide groove 601.

[0068] In this embodiment, the transmission rod 6 can move in the second direction when it moves in the first direction by means of the plurality of second guide grooves 601 obliquely arranged on the second transmission plate 6, thereby realizing the linkage of the first guide rail 2 and the second guide rail 3 in action, that is, the egg tray 4 can move in the first direction and the second direction at the same time by only pressing the operating rod 502 once, thereby realizing the adjustment of the spacing between two adjacent egg trays 4, and after the adjustment is in place, the spacing between the two adjacent egg trays 4 in the first direction and the spacing in the second direction are the same. Of course, the target spacing between the two adjacent egg trays 4 can still be adaptively adjusted according to the use.

[0069] In order to further improve the sliding stability of the second guide rail 3, as Figure 5 and Figure 6As shown in , a plurality of third guide grooves 602 are provided on the second transmission plate 6, and in the first direction, the second guide groove 601 and the third guide groove 602 are respectively provided at both ends of the second transmission plate 6, and the plurality of third guide grooves 602 are provided in one-to-one correspondence with the first slide groove 301 or the second slide groove 302 of the second guide rail 3, and one of the transmission members 401 located on each second guide rail 3 is provided in the third guide groove 602. The cooperation of the plurality of third guide grooves 602 and the plurality of second guide grooves 601 is conducive to further improving the sliding stability of the second guide rail 3, thereby facilitating improving the supporting stability of the egg tray 4 facing the poultry eggs 100 during the spacing adjustment process.

[0070] In terms of specific structure, each third guide groove 602 is an inclined groove set at an angle to the second direction, and the inclination direction and angle change rule of the plurality of third guide grooves 602 are the same as those of the plurality of second guide grooves 601. A transmission rod on the same second guide rail 3 is slidably set in the second guide groove 601, and another transmission rod is slidably set in the third guide groove 602, and under the guidance of the corresponding guide groove, two adjacent second guide rails 3 are brought closer to or farther from each other. Of course, the structure of the third guide groove 602 can also be omitted according to the use requirements. In this case, the second guide rail 3 can also be adjusted in position only by a transmission rod under the guidance of the second guide groove 601.

[0071] When the supporting device in this embodiment is in use and needs to be switched from the first state to the second state, a downward force is first applied to the operating rod 502, so that the first transmission plates 5 on both sides rotate downward synchronously, and each transmission shaft 202 slides in the corresponding first guide groove 501, so that each egg tray 4 slides along the first direction with the first guide rail 2. Since the distance between the two adjacent first guide rails 2 increases, the distance between the two adjacent egg trays 4 in the first direction also increases.

[0072] At the same time, under the guiding action of the second guide groove 601 and the third guide groove 602, each second guide rail 3 slides in the second direction, and the distance between two adjacent second guide rails 3 increases, thereby increasing the distance between two adjacent egg trays 4 in the second direction, until the transmission shaft 202 abuts against the top end of the first guide groove 501 and the transmission rod abuts against the end of the second guide groove 601 or the third guide groove 602 away from the operating rod 502, each first guide rail 2 and second guide rail 3 is restricted from continuing to slide, thereby adjusting the supporting device to the second state where each egg tray 4 is spaced apart in the first direction and the second direction.

[0073] The supporting device in this embodiment is provided with a plurality of first guide rails 2, second guide rails 3, transmission rods on the egg tray 4, and a first transmission plate 5 and a second transmission plate 6, and enables the first guide rails 2 and the second guide rails 3 to be linked in the first direction and the second direction, so that the egg tray 4 can be switched between a first state of aggregation and a second state of separation. It not only occupies a small area, but also has good adjustment convenience, so that the function of the supporting device is more abundant, and it is conducive to meeting different usage requirements.

[0074] In addition, this embodiment also relates to a sorting system, which includes the supporting device as described above.

[0075] The sorting system described in this embodiment, by providing the above-mentioned supporting device, is convenient for adjusting the distance between the egg trays 4 and has high adjustment convenience, which is not only convenient for detecting individual poultry eggs, but also helps to improve the efficiency of sorting the poultry eggs 100.

[0076] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
