Description

Technical Field

[0001] The utility model relates to the technical field of seedling tray stacking equipment components, in particular to an adjustable stacking mechanism. Background Art

[0002] A seedling tray stacking machine is a device used to automatically stack seedling trays. A conveyor mechanism transports the seedling trays to a stacking station, where they are then raised and lowered to stack them on the stacking mechanism. The stacking mechanism typically consists of swingable claws. When the stacking station is raised, it lifts the seedling tray, pushing the claws. Once the seedling tray is above the claws, the claws return to their original position, supporting the bottom of the tray. The stacking station then lowers back to its original position. However, the swing angle of the claws in traditional stacking mechanisms is not adjustable, requiring the size of the seedling tray to correspond to the size of the claws. Consequently, a single type of stacking mechanism can only be used to stack seedling trays of a single size. Utility Model Content

[0012] The first limiting plate abuts against the adjusting component.

[0013] Preferably, the adjustment assembly includes a telescopic rod, one end of which is arranged on the mounting seat, and the other end extends in a direction close to the first limit plate. When the reset structure forces the swinging support frame to swing toward the direction close to the seedling tray, the first limit plate can abut the telescopic rod.

[0014] Preferably, the mounting base comprises:

[0015] A limiting baffle extends along the height direction of the seedling tray, and the limiting baffle forms a longitudinal limiting portion adjacent to one side of the seedling tray, and an opening is provided on the longitudinal limiting portion;

[0016] The support frame is connected to the limit baffle and is located on a side of the limit baffle away from the stacking station. The rotating part is rotatably connected to the support frame so that the supporting claw is exposed outside the opening.

[0017] Preferably, a second limit plate is provided on the supporting claw near the supporting bottom position, and the second limit plate is located on the relatively inner side of the limit baffle.

[0039] See Figures 1 to 6 The present embodiment provides an adjustable stacking mechanism, including a stacking mechanism body 100, which is used to be installed on both sides of the stacking station 210 of the seedling tray stacking equipment 200. The stacking station 210 can lift and stack the seedling trays 300 on the stacking mechanism body 100 by lifting. The stacking mechanism body 100 includes a mounting seat 1, a swinging support frame 2, an adjustment component 3 and a reset structure 4.

[0040] The mounting base 1 is used for being mounted on the seedling tray stacking device 200 .

[0041] The swing-type support frame 2 is rotatably mounted on the mounting base 1 and can swing toward or away from the seedling tray 300. A reset structure 4 is provided between the swing-type support frame 2 and the mounting base 1. When the stacking station 210 rises to the first position, the seedling tray 300 forces the swing-type support frame 2 to swing away from the seedling tray 300. When the stacking station 210 continues to rise to the second position, the reset structure 4 forces the swing-type support frame 2 to swing toward the seedling tray 300, thereby lifting the bottom of the seedling tray 300.

[0042] The adjustment component 3 is arranged on the mounting base 1 and connected to the swing type supporting frame 2 , and is used for adjusting the swing angle of the swing type supporting frame 2 .

[0043] The stacking station 210 is in the second position, and after the stacking station 210 is lowered, the swinging supporting frames 2 on both sides can support the bottom of the seedling tray 300 to prevent the seedling tray 300 from falling. The stacking station 210 repeats the rising and falling process to stack the seedling tray 300 on the swinging supporting frames 2 in sequence.

[0044] The adjustment component 3 can adjust the swinging angle of the swinging support frame 2, that is, when the stacking station 210 is in the second position, the swinging support frame 2 is reset to its position under the action of the reset structure 4, thereby adjusting the distance between the swinging support frames 2 on both sides after the reset. When the size of the seedling tray 300 is small, the distance between the swinging support frames 2 on both sides can be set smaller. When the size of the seedling tray 300 is large, the distance between the swinging support frames 2 on both sides can be set larger accordingly, so that a single specification of swinging support frame 2 can be used for stacking seedling trays 300 of different sizes.

[0045] The adjustable stacking mechanism provided in this embodiment is achieved by arranging a stacking mechanism main body 100 on both sides of the stacking station 210, and rotatably arranging a swinging support frame 2 on the mounting seat 1 of the stacking mechanism main body 100, as well as an adjustment component 3 connected to the swinging support frame 2, so that the adjustment component 3 can adjust the distance between the swinging support frames 2 on both sides of the stacking station 210 after they are reset, thereby adapting to seedling trays 300 of different sizes, thereby solving the technical problems in the background technology.

[0046] Further, see Figure 3A pushing portion 21 is provided on the side of the swing-type supporting frame 2 adjacent to the stacking station 210. When the stacking station 210 rises to the first position, the seedling tray 300 pushes the pushing portion 21, so that the swing-type supporting frame 2 can swing away from the seedling tray 300; when the stacking station 210 continues to rise to the second position, the pushing portion 21 is separated from the seedling tray 300, and the swing-type supporting frame 2 moves toward the seedling tray 300 under the action of the reset structure 4.

[0047] For further information, please see Figure 3 :

[0048] A rotating portion 22 is formed at the connection between the swing-type supporting frame 2 and the mounting base 1 , and a supporting claw 23 and a first limiting plate 24 are respectively formed at two ends of the swing-type supporting frame 2 relative to the rotating portion 22 .

[0049] The supporting claw 23 forms a pushing portion 21 on the side close to the stacking station 210 , and forms a supporting bottom portion 231 on the side away from the stacking station 210 . The supporting bottom portion 231 is used to lift the bottom of the seedling tray 300 .

[0050] The first limiting plate 24 abuts against the adjusting assembly 3 .

[0051] Among them, the seedling tray 300 pushes the pushing part 21 to make the rotating part 22 rotate relative to the mounting seat 1, thereby driving the first limit plate 24 to rotate. After the seedling tray 300 breaks away from the pushing part 21, the reset structure 4 can force the supporting claw 23 and the rotating part 22 to rotate together, thereby driving the first limit plate 24 to rotate. When the first limit plate 24 swings and abuts the adjusting component 3, the swinging support frame 2 swings to the lowest position, and the supporting bottom part 231 can support the bottom of the seedling tray 300.

[0052] For further information, please see Figure 3 The adjustment component 3 includes a telescopic rod 31, one end of the telescopic rod 31 is set on the mounting seat 1, and the other end extends in the direction close to the first limit plate 24. When the reset structure 4 forces the swinging support frame 2 to swing toward the direction close to the seedling tray 300, the first limit plate 24 can abut the telescopic rod 31.

[0053] Among them, when the telescopic rod 31 is extended, the swinging support frame 2 can swing to a smaller range, and the distance between the swinging support frames 2 on both sides after resetting is larger, which is suitable for seedling trays 300 with slightly larger sizes; when the telescopic rod 31 is shortened, the swinging support frame 3 can swing to a larger range, and the distance between the swinging support frames 2 on both sides after resetting is smaller, which is suitable for seedling trays 300 with slightly smaller sizes.

[0054] Further, see Figure 3 and Figure 4 The mounting seat 1 includes a limiting baffle 11 and a supporting frame 12.

[0055] The limiting baffle 11 extends along the height direction of the seedling tray 300, and forms a longitudinal limiting portion 111 on the side of the limiting baffle 11 adjacent to the seedling tray 300. The longitudinal limiting portion 111 is provided with an opening 111a.

[0056] The support frame 12 is connected to the limiting baffle 11 and is located on a side of the limiting baffle 11 away from the stacking station 210 . The rotating portion 22 rotates the connected support frame 12 to expose the claws 23 outside the opening 111 a .

[0057] Among them, the longitudinal limiting part 111 is the outer wall of the limiting baffle 11 adjacent to the seedling tray 300. The longitudinal limiting part 111 is used to limit the rising direction of the seedling tray 300 to prevent the seedling tray 300 from tipping over during the rising process. The swinging supporting frame 2 is located on the side of the limiting baffle 11 away from the seedling tray 300, and the supporting claw 23 is partially exposed from the opening 111a, so as to facilitate the seedling tray 300 to push or support the bottom of the seedling tray 300.

[0058] Further, see Figure 3 A second limiting plate 232 is provided on the supporting claw 23 near the supporting bottom 231. The second limiting plate 232 is located on the inner side of the limiting baffle 11. When the reset structure 4 forces the swinging supporting frame 2 to swing toward the direction close to the seedling tray 300, the second limiting plate 232 can abut the inner wall of the opening 111a.

[0059] Specifically, when the telescopic rod 31 is at its shortest, the second limiting plate 232 can abut against the inner wall of the opening 111 a after the swing-type supporting frame 2 is reset.

[0060] Furthermore, the reset structure 4 includes a spring, one end of the spring is connected to the swing-type supporting frame 2 , and the other end is connected to the mounting base 1 .

[0061] Specifically, one end of the spring is connected to the supporting claw 23 , and the other end is connected to the supporting frame 12 , so as to push the supporting claw 23 to move away from the supporting frame 12 , thereby forcing the swing-type supporting frame 2 to swing.

[0062] Furthermore, the telescopic rod 31 is a pneumatic rod so as to accurately control the length.

[0063] Working principle:

[0064] The stacking station 210 is in the first position when it rises and the seedling tray 300 is lifted. During the rising process, the seedling tray 300 can push the swinging supporting frame 2, so that the swinging supporting frames 2 on both sides of the stacking station 210 swing away from each other, thereby allowing the seedling tray 300 to pass. At this time, the stacking station 210 is in the first position; when the stacking station 210 continues to rise and the seedling tray 300 exceeds the height of the swinging supporting frame 2, the seedling tray 300 no longer pushes the swinging supporting frame 2, and the swinging supporting frames 2 on both sides can swing towards each other under the action of the resetting structure 4. At this time, the stacking station 210 is in the second position. After the stacking station 210 descends, the swinging supporting frames 2 on both sides can support the bottom of the seedling tray 300 to prevent the seedling tray 300 from falling. The stacking station 210 repeats the rising and falling process to stack the seedling tray 300 on the swinging supporting frame 2 in sequence.

[0065] The adjustment component 3 can adjust the swinging angle of the swinging support frame 2, that is, when the stacking station 210 is in the second position, the swinging support frame 2 is reset to its position under the action of the reset structure 4, thereby adjusting the distance between the swinging support frames 2 on both sides after the reset. When the size of the seedling tray 300 is small, the distance between the swinging support frames 2 on both sides can be set smaller. When the size of the seedling tray 300 is large, the distance between the swinging support frames 2 on both sides can be set larger accordingly, so that a single specification of swinging support frame 2 can be used for stacking seedling trays 300 of different sizes.
