Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery and equipment, in particular to an automatic bag seedling delivery device. Background Art

[0002] In modern agricultural production, seedling transplanting is a common agronomic operation, which refers to the process of removing seedlings from the seedbed, transplanting them into prepared soil after proper treatment.

[0003] To facilitate seedling transplanting, you can also use seedling bags for seedling cultivation. In this case, the seedlings are called bagged seedlings. The seedling bags are usually made of biodegradable materials and do not need to be removed during transplanting. The seedlings are first grown to a certain size in the seedling bag, and then transplanted with the seedling bag. After a certain period of time after transplanting, the seedling bag will degrade on its own.

Existing seedling transplanters can automatically deliver seedlings, such as bagged seedlings, into pre-dug planting pits. However, manual delivery is still required, with operators manually placing each bag of seedlings into the corresponding cups. This is cumbersome and labor-intensive, requiring constant concentration to avoid misplacement. Utility Model Content

[0039] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be internal communication between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0040] Please refer to Figures 1 to 6 The utility model provides an automatic bag seedling delivery device, which mainly includes a fixed platform 10, a linear module 20, a mounting frame 30, a driving wheel 41, a driven wheel 42, a transmission belt 43, a driving motor 44 and a tray 50.

[0041] The fixed platform 10 is a square flat plate structure, and a drop hole 11 is provided in the middle of the fixed platform 10 so that when the bagged seedlings are located above the drop hole 11, they can drop downward through the drop hole 11. The fixed platform 10 is fixedly mounted on a transplanting device such as a seedling transplanter, and the cup body of the transplanting device such as the seedling transplanter is located directly below the drop hole 11 to receive the bagged seedlings that fall from the drop hole 11. It is understandable that the cup bodies of some transplanting devices such as seedling transplanters are mobile, such as being arranged on a turntable, and having multiple cup bodies. At this time, when the multiple cup bodies rotate to a certain position with the turntable, a certain cup body can be located directly below the drop hole 11.

[0042] Two linear modules 20 are fixedly mounted on opposite sides of the fixed platform 10. The linear modules 20 move in the longitudinal direction of the fixed platform 10. Each linear module 20 is equipped with a mounting bracket 30 that can be driven by the linear module 20 to move longitudinally along the fixed platform 10. In this utility model, the two mounting brackets 30 are driven independently by the two linear modules 20, but they move simultaneously, meaning that the two linear modules 20 move in unison to maintain their movement. Driven by the linear modules 20, the two mounting brackets 30 are capable of longitudinal movement.

[0043] There are two driving wheels 41, each mounted on one end of a mounting frame 30. Both driving wheels 41 are mounted on one mounting frame 30, one at each end of the mounting frame 30. The driving wheels 41 are rotatably mounted on the mounting frame 30 to move longitudinally with the mounting frame 30. A drive motor 44 is fixedly mounted on the mounting frame 30 to drive the driving wheels 41 in rotation. The mounting frame 30 to which the drive motor 44 is fixedly mounted and the mounting frame 30 to which the driving wheels 41 are mounted are the same mounting frame 30. In this case, the drive motor 44 can move longitudinally with the mounting frame 30. The output shaft of the drive motor 44 is connected to the rotating shaft of the driving wheel 41 via a coupling, thereby driving the driving wheel 41 in rotation.

[0044] There are two driven wheels 42, each mounted on either end of another mounting frame 30. Both driven wheels 42 are mounted on a single mounting frame 30, one at each end of the mounting frame 30. The driven wheels 42 are rotatably mounted on the mounting frame 30 to move longitudinally with the mounting frame 30. The driven wheels 42 and the driving wheel 41 are mounted on different mounting frames 30. In this case, the driven wheels 42 and the driving wheel 41 are located on opposite sides of the fixed platform 10.

[0045] There are two conveyor belts 43, and the two conveyor belts 43 are respectively and one-to-one mounted on the driving wheel 41 and the driven wheel 42 located in the same end direction, that is, one conveyor belt 43 is mounted on one driving wheel 41 and the driven wheel 42, and the other conveyor belt 43 is mounted on the other driving wheel 41 and the driven wheel 42, and the two conveyor belts 43 are parallel to each other.

[0046] The drive motor 44 drives the driving wheels 41 to rotate simultaneously, and at this time, the two conveyor belts 43 run synchronously. In a preferred embodiment, the drive motor 44 is a dual-shaft motor. The drive motor 44 of the dual-shaft motor is located between the two driving wheels 41 and is connected to the two driving wheels 41 via two output shafts, one-to-one. In this case, the two driving wheels 41 can be driven to rotate simultaneously by a single drive motor 44.

[0047] In this exemplary embodiment, the linear module 20 is positioned at the bottom of the fixed platform 10, without obstructing the top or sides of the fixed platform 10. The linear module 20 is a ball screw type, a common component and not described in detail here. The ball screw type linear module 20 includes a slider, and the mounting bracket 30 is fixedly mounted on the slider. When the ball screw type linear module 20 drives the slider to move, it also drives the mounting bracket 30 to move linearly.

[0048] The main body of the mounting frame 30, on which the driven wheel 42 is mounted, is no higher than the top surface of the fixed platform 10. At this point, the mounting frame 30 does not obstruct the top of the fixed platform 10 at the position between the two conveyor belts 43, allowing the pallet 50 to exit from this position. The mounting frame 30, on which the driven wheel 42 is mounted, has upwardly directed mounting portions 31 at each end. These mounting portions 31 are located above the top surface of the fixed platform 10, and the driven wheel 42 is mounted on these mounting portions 31. Similarly, the driving wheel 41 is also mounted on the mounting portions 31 at each end of the mounting frame 30.

[0049] In this exemplary embodiment, the conveying direction of the conveyor belt 43 is from the driving wheel 41 to the driven wheel 42. In this case, the conveyor belt 43 is horizontally conveyed. Of course, it is understood that in other preferred embodiments, the conveying direction of the conveyor belt 43 can also be from the driven wheel 42 to the driving wheel 41.

[0050] Tray 50 is used to hold bagged seedlings. Tray 50 is provided with a plurality of through-holes 51 for placing bagged seedlings. During operation, the bagged seedlings are placed within the through-holes 51. The through-holes 51 are vertically extending, meaning that both the top and bottom of the through-holes 51 are open. In this exemplary embodiment, tray 50 is a cylindrical hole structure, arranged upright. The through-holes 51 are evenly distributed in multiple rows. For example, in this exemplary embodiment, the through-holes 51 are arranged in a 4x4 pattern.

[0051] The tray 50 is provided with a placement plate 52 on both sides so that the tray 50 can be placed on the conveyor belts 43 on both sides through the placement plate 52 and be transported laterally by the conveyor belts 43. During implementation, the tray 50 is placed on the two conveyor belts 43 on both sides through the placement plates 52 on both sides. The conveyor belts 43 can be transported laterally under the drive of the drive motor 44, that is, the tray 50 is moved laterally, thereby driving the bagged seedlings located in the placement through-holes 51 thereof to move laterally together. When the tray 50 is placed on the conveyor belts 43 on both sides through the placement plates 52, the bottom of the tray 50 does not abut against the top of the fixed platform 10, so as to ensure that the tray 50 moves with the conveyor belts 43. The tray 50 is placed on the conveyor belt 43 and moves laterally with the conveyor belt 43. At the same time, the conveyor belt 43 can be driven by the linear module 20 to drive the mounting frame 30 to move longitudinally. Under the action of the linear module 20 and the conveyor belt 43, the tray 50 can make a combined longitudinal and transverse movement. Through the combined longitudinal and transverse movement, the tray 50 is driven to move to a certain position so that the placement through hole 51 of the tray 50 can face the drop hole 11 of the fixed platform 10. When the placement through hole 51 faces the drop hole 11, if there is a bag of seedlings in the placement through hole 51, The bagged seedlings can then fall downward through the drop hole 11 to achieve bagged seedling delivery. This seedling delivery method only requires placing the tray 50 loaded with bagged seedlings on the conveyor belt 43, and then the linear module 20 and the drive motor 44 are driven according to a preset program to align the placement through hole 51 of the tray 50 with the drop hole 11 to enable the bagged seedlings in the placement through hole 51 to fall downward through the drop hole 11 to achieve automatic bagged seedling delivery. This seedling delivery method does not require the operator to manually put the bagged seedlings in one bag at a time. It has a simple structure, easy operation, low labor intensity, and a high degree of automation, which helps to reduce work intensity and improve efficiency.

[0052] Preferably, the tray 50 is provided with a side groove 53 on one side, which passes through the placement hole 51, and a cross-plate 54 is inserted into the side groove 53. During implementation, the bagged seedlings need to be placed in the placement hole 51 of the tray 50 in advance. However, since the bottom of the placement hole 51 is hollow, it is relatively difficult for the bagged seedlings to move with the tray 50. In this case, the side groove 53 and the cross-plate 54 are provided. When in use, the cross-plate 54 is first inserted into the side groove 53. At this time, the placement hole 51 of the tray 50 can be temporarily blocked by the cross-plate 54. When the tray 50 is moved, the bagged seedlings will not fall out of the placement hole 51 of the tray 50, making it easy to place the tray 50 and the bagged seedlings on the conveyor belt 43. After the tray 50 and the bagged seedlings are placed on the conveyor belt 43, the cross-plate 54 is immediately pulled out. At this time, the bagged seedlings fall downward and are placed on the fixed platform 10, and can move with the movement of the tray 50.

[0053] The conveyor belt 43 is provided with a plurality of limiting protrusions 45 along its extension direction, and the placement plate 52 is provided with a plurality of limiting grooves 55 that match the limiting protrusions 45, so that when the tray 50 is placed on the conveyor belts 43 on both sides through the placement plate 52, the limiting grooves 55 are sleeved on the limiting protrusions 45. Considering that when the tray 50 is placed on the conveyor belt 43 and the bagged seedlings fall down and contact the fixed platform 10, there will be friction between the two. If this friction is greater than the friction between the tray 50 and the conveyor belt 43, it may affect the movement of the tray 50 driven by the conveyor belt 43. At this time, the conveyor belt 43 is provided with a limiting protrusion 45, and the placement plate 52 is provided with a limiting groove 55. When the tray 50 is placed on the conveyor belts 43 on both sides, the limiting groove 55 is sleeved on the limiting protrusion 45. At this time, through the cooperation of the limiting protrusion 45 and the limiting groove 55, it is ensured that the conveyor belt 43 can drive the tray 50 to move, or the position of the tray 50 placed on the conveyor belt 43 is relatively fixed, and the two do not move, so as to achieve accurate bag seedling delivery. At the same time, the limiting protrusion 45 can also play a positioning role. For example, when placing the tray 50 on the conveyor belt 43, it can only be placed on the limiting protrusion 45 of the conveyor belt 43. In this way, the position of the tray 50 is fixed each time, ensuring the synchronization of the unloading.

[0054] The placement plate 52 includes a connecting vertical plate 521 fixedly arranged on the side of the tray 50 and a placement horizontal plate 522 located on the top of the connecting vertical plate 521 and extending laterally outward and used to be placed on the conveyor belt 43. A receiving cavity is formed between the vertical plates 521 of the placement plate 52 on both sides of the tray 50 and the top of the tray 50. The bottom of the tray 50 can be inserted into the receiving cavity to achieve stacking of two trays 50. Figure 6 As shown, this method enables multiple trays 50 to be stacked on each other, making it easier to store and receive the trays 50. Positioning slots 523 are provided on the horizontal plate 522 of the placement plate 52, and when two trays 50 are stacked on each other, the bottom of the vertical plate 521 of the upper tray 50 fits into the positioning slots 523 of the horizontal plate 522 of the upper tray 50. At this time, the two stacked trays 50 can not only be limited in the vertical direction, but also can be limited on both sides of the two placement plates 52 by the positioning slots 523 to ensure that the two trays 50 do not move relative to each other, thereby ensuring the stability of the stacking.

[0055] The following is an exemplary embodiment of an automatic seedling delivery method for bagged seedlings, which uses the above-mentioned automatic seedling delivery device for bagged seedlings and includes the following steps:

[0056] S1. The linear module 20 drives the two mounting frames 30 to move simultaneously, and moves the conveyor belt 43 to a certain position.

[0057] by Figure 7For example, at this time, the linear module 20 drives the two mounting frames 30 to move to the right edge of the fixed platform 10 , and the conveyor belt 43 also moves to the right edge of the fixed platform 10 .

[0058] S2. Place the bagged seedlings into the placement through-hole 51 of the tray 50 and place them on the two conveyor belts 43 together with the tray 50. At this time, the tray 50 is located at the conveying front end of the conveyor belt 43.

[0059] During implementation, the tray 50 with the bagged seedlings is placed at the front end of the conveyor belt 43, where the front end of the conveyor belt 43 is the end close to the drive motor 44. At this time, the tray 50 is located at the upper right corner of the fixed platform 10, as shown in FIG. Figure 8 shown.

[0060] S3 , the tray 50 is placed on the two conveyor belts 43 , and the drive motor 44 is started to drive the conveyor belts 43 through the driving wheel 41 to intermittently drive the tray 50 to move on the fixed platform 10 toward the rear end of the conveyor belts 43 .

[0061] The driving motor 44 drives the driving wheel 41 to drive the conveyor belt 43 to operate intermittently. At this time, the movement of the tray 50 on the fixed platform 10 toward the conveying rear end of the conveyor belt 43 is also intermittent, that is, the lateral movement of the tray 50 is intermittent. The intermittent movement is first driven by the driving motor 44 to drive the driving wheel 41 to drive the conveyor belt 43 so that the front end of the tray 50 (towards the conveying rear end of the conveyor belt 43) is aligned with the drop holes 11 of the fixed platform 10 in the longitudinal direction. Then the driving motor 44 stops and after the bag seedlings in the placement holes 51 of the row are delivered, the driving motor 44 drives the driving wheel 41 to drive the conveyor belt 43 to deliver the bag seedlings in the placement holes 51 of the next row of trays 50 to be aligned with the drop holes 11 of the fixed platform 10 in the longitudinal direction. Then the driving motor 44 stops again to deliver the bag seedlings in the placement holes 51 of the row, and so on.

[0062] At the same time, the linear module 20 drives the two mounting frames 30 to move longitudinally, thereby driving the conveyor belts 43 and the trays 50 thereon to move longitudinally.

[0063] The linear module 20 drives the conveyor belt 43 and the tray 50 to move longitudinally. When the conveyor belt 43 stops conveying and a row of placement holes 51 of the tray 50 are aligned with the drop holes 11 of the fixed platform 10 in the longitudinal direction, the linear module 20 drives the conveyor belt 43 and the tray 50 to move longitudinally, and the placement holes 51 in the row are aligned with the drop holes 11 in sequence.

[0064] When the tray 50 moves horizontally and vertically, the placement through hole 51 of the tray 50 is aligned with the drop hole 11, and the bag seedlings placed in the placement through hole 51 fall downward through the drop hole 11, thereby delivering the bag seedlings.

[0065] As in this exemplary embodiment, at the beginning, the tray 50 is located at the upper right corner of the fixed platform 10, and then the driving motor 44 drives the conveyor belt 43 to drive the front row of through holes 51 of the tray 50 to face the drop holes 11 of the fixed platform 10 in the longitudinal direction, and then the driving motor 44 stops, and the linear module 20 starts to drive the mounting frame 30 to move longitudinally, so that the conveyor belt 43 and the tray 50 move longitudinally to the left, and the vertical row of through holes 51 on the tray 50 is aligned with the drop holes 11 in sequence, and the seedlings in the bags are arranged in sequence. When the seedlings in the bag of seedlings in the last through hole 51 of the vertical row are delivered, the linear module 20 stops, and then the driving motor 44 drives the conveyor belt 43 to drive the tray 50 forward so that the through holes 51 of the next vertical row are aligned with the drop holes 11 of the fixed platform 10 in the longitudinal direction, and then the driving motor 44 stops, and the linear module 20 starts to drive the mounting frame 30 to move longitudinally, so that the conveyor belt 43 and the tray 50 move longitudinally to the right, and the through holes 51 of the vertical row on the tray 50 are aligned with the drop holes 11 in sequence, and the bag seedlings therein fall out in sequence. When the seedlings in the bag of seedlings in the last through hole 51 of the vertical row are delivered, the linear module 20 stops, and then the driving motor 44 drives the conveyor belt 43 to drive the tray 50 forward so that the through holes 51 of the next vertical row are aligned with the drop holes 11 of the fixed platform 10 in the longitudinal direction, and then the driving motor 44 stops, and the linear module 20 starts to drive the mounting frame 30 to move longitudinally, so that the conveyor belt 43 and the tray 50 move longitudinally to the left, and the through holes 51 of the vertical row on the tray 50 are aligned with the drop holes 11 in sequence, and the bag seedlings therein fall out in sequence. After the seedlings are delivered to the last through-hole 51 in the longitudinal row, the linear module 20 stops, and the drive motor 44 drives the conveyor belt 43 to drive the tray 50 forward so that the through-hole 51 in the next longitudinal row is aligned with the drop-out hole 11 of the fixed platform 10 in the longitudinal direction. The drive motor 44 then stops, and the linear module 20 starts to drive the mounting frame 30 to move longitudinally, allowing the conveyor belt 43 and the tray 50 to move longitudinally to the right. The through-holes 51 in the longitudinal row on the tray 50 are aligned with the drop-out hole 11 in sequence, and the seedlings in the bags drop out in sequence. At this point, all the through-holes 51 on the tray 50 pass through the drop-out hole 11, so that the seedlings in the bags (if any) in all the through-holes 51 can be delivered automatically. The linear module 20 then drives the two mounting frames 30 to reset, i.e., move to the right side edge of the fixed platform 10. If the seedlings continue to be delivered, the above-mentioned method is installed and a new tray 50 with bagged seedlings is placed on the conveyor belt 43. And when the limiting protrusion 45 is provided on the conveyor belt 43, the limiting protrusion 45 can be used as a positioning, so that the tray 50 can be accurately placed in place (consistent with the placement position of the previous tray 50), maintaining the consistency of seedling delivery of each tray 50.

[0066] The empty tray 50 after the seedlings are delivered is moved further toward the rear end by the conveyor belt 43 until it falls out from the side of the fixed platform 10 , and a new tray 50 with bagged seedlings is placed on the conveyor belt 43 in the above manner and the bagged seedlings are delivered.

[0067] On one side of the driven wheel 42, the top of the fixed platform 10 is unobstructed. Therefore, as the conveyor belt 43 gradually conveys the empty pallet 50, it can eventually fall from the conveyor belt 43. This structure and method eliminates the need to manually remove the empty pallet, reducing the number of operations. The dropped empty pallet can be collected by a frame. Of course, it is understood that the empty pallet can also be manually removed from the conveyor belt 43.

[0068] The utility model discloses an automatic seedling feeding device for bagged seedlings, which can realize automatic seedling feeding of bagged seedlings. This seedling feeding method does not require an operator to manually put bagged seedlings into the bag one by one. It has a simple structure, is easy to operate, has low labor intensity, and a high degree of automation, which helps to reduce work intensity and improve efficiency.

[0069] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
