Description

Technical Field

[0001] This invention relates to the field of agricultural seedling technology, and in particular to a fruit tree seedling breeding spacing adjustment structure. Background Technology

[0002] Fruit tree seedling breeding refers to the process of obtaining seedlings of fruit trees through seed cultivation, cuttings, and other methods. Once the seedlings have matured, they can be transplanted to the planting area. Unlike crops such as rice, the cultivation time for fruit tree seedlings is relatively long, generally requiring 1-2 years, and the plants need to grow to a certain diameter before they can be transplanted. Therefore, the size of fruit tree seedlings varies considerably throughout the entire seedling cultivation process.

[0003] Existing technology discloses a seed spacing adjustment device for rice breeding (publication number: CN219182214U), relating to the field of rice breeding technology. It includes a chute, with rectangular columns fixedly installed on both sides of the chute's outer wall. A round rod is fixedly inserted into the inner wall of the chute, and a first outer frame is fixedly fitted onto the outer wall of the round rod. A first metal rod is fixedly inserted into the inner wall of the first outer frame. Two sets of cross-shaped movable frames are movably fitted onto the outer wall of the first metal rod, with the two sets of cross-shaped movable frames facing opposite directions. Two sets of second metal rods are movably inserted into the joints of the two sets of cross-shaped movable frames. Activating the electric telescopic rod causes the cross-shaped movable frames to retract inward or expand outward. Simultaneously, the retraction or expansion of the cross-shaped movable frames moves the second outer frame. Since the spacing of the cross-shaped movable frames is equal, this causes the second outer frame to move evenly, thus uniformly adjusting the spacing between the breeding boxes.

[0004] Existing technologies like the one described above can only adjust the seedling spacing in one direction during the seedling cultivation process, while the plant's growth radius increases circumferentially within the space, and its structure cannot be well adapted to existing seedling beds.

[0005] Therefore, it is necessary to provide a fruit tree seedling breeding spacing adjustment structure to solve the above-mentioned technical problems. Summary of the Invention

[0006] In view of the above situation and to overcome the defects of the existing technology, the present invention provides a fruit tree seedling breeding spacing adjustment structure that can adjust the spacing of seedlings in space to adapt to seedlings at different growth stages, while being compatible with existing seedbed structures.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A fruit tree seedling breeding spacing adjustment structure includes: a seedbed frame supporting the upper structure, a support frame fixedly installed on the seedbed frame, a seedling board slidably installed on the support frame, and the seedling board being driven by a drive unit; The seedbed frame includes a support frame, the lower end of which is a support leg, and the upper end of the support leg is fixedly installed with a crossbeam. The upper end of the crossbeam is fixedly installed with a rectangular frame for blocking the seedlings. The support frame is a frame structure and is horizontally fixedly installed on the upper end of the crossbeam; The seedling board includes multiple placement board units, each placement board being formed by hinged end to end of multiple independent support plates. The support plates have through holes for water to pass through, and short columns are fixedly installed at the lower ends of the multiple support plates. The short columns are located at the upper end of the support frame and are slidably connected to the support frame. The drive unit includes a sleeve fixedly installed at the lower end of the crossbeam, a lead screw rotatably installed inside the sleeve, a slider threadedly installed on the outer periphery of the lead screw, a handwheel fixedly installed at one end of the lead screw, the slider slidably installed inside the sleeve, and a connecting assembly installed on the sleeve, the connecting assembly pushing the placement plate to slide in the short axis direction of the bracket; The placement board is folded and slid to create a gap at the upper end of the support frame, increasing the distance between adjacent placement boards, thereby increasing the distance between the seedlings located at the upper end of the placement board.

[0008] Preferably, the support frame includes a cross frame, which is a cross-shaped grid frame welded from multiple mutually perpendicular channel steels. A sliding groove is provided in the middle of the channel steel, and the short column is located in the sliding groove and can slide inside the sliding groove.

[0009] Preferably, each of the placement plate units includes two support plates, namely a first support plate and a second support plate. The first support plate and the second support plate are hinged to each other. When the first support plate and the second support plate are fully unfolded, they cover the upper part of the cross frame. This is a form 1, which is suitable for placing and cultivating smaller seedlings.

[0010] Preferably, in the first form, the second support plate is folded towards the first support plate. The first and second support plates have the same specifications. The second support plate is located at the upper end of the first support plate, and a gap of the width of the second support plate is formed between adjacent plates. This is the second form, which is suitable for placing and cultivating larger seedlings.

[0011] Preferably, the connecting assembly includes a stop block fixedly installed on the upper end of the slider. The stop block extends vertically upward through the slot opened at the upper end of the sleeve and is located at the lower end of the placement plate. A connecting block corresponding to the position of the stop block is vertically fixedly installed on the lower end face of the placement plate. The stop block can push the connecting block and the placement plate fixedly installed on the connecting block to move.

[0012] Preferably, the spacing between the short columns at the lower end of the placement plate is the same as the spacing between the adjacent sliding grooves in the cross frame, and the short columns support the placement plate to slide in the sliding grooves.

[0013] Preferably, the driving part is parallel to the short axis of the seedbed frame, and the driving part is installed at intervals at the lower end of the seedling board. The adjacent placement boards are staggered, forming a third form, which is suitable for placing and cultivating larger seedlings.

[0014] Preferably, the first support plate and the second support plate are composed of wire mesh and structural frame, the edge of the wire mesh is fixedly installed on the inner side of the structural frame, and adjacent structural frames are connected by hinges.

[0015] Preferably, the support frame includes a cross frame, which is a cross-shaped frame welded from multiple channel steels spaced at ° intervals, and the short columns of the placement plate are located in the grooves of the cross frame.

[0016] Compared with the prior art, the present invention has the following beneficial effects: (1) The present invention sets the seedling board as multiple placement board units that are hinged together by the first support plate and the second support plate, and cooperates with the sliding groove of the support frame and the screw transmission mechanism of the drive unit, so that the placement board can switch between three forms: fully unfolded, single board folded and staggered sliding. On the same seedbed, the multi-level spacing adjustment from dense cultivation to bidirectional spacing expansion is realized, which satisfies the different needs of fruit tree seedlings for longitudinal and transverse growth space at different growth stages. (2) The present invention sets up a cross-shaped grid frame made of channel steel on the support frame and opens a sliding groove in the middle of the channel steel. The short column fixedly installed at the lower end of the placement plate slides smoothly in the sliding groove, so that each placement plate maintains uniform guiding accuracy and support stability during the sliding adjustment process, avoiding uneven spacing caused by offset or shaking, and ensuring the consistency of seedling growth space. (3) By folding the second support plate of each placement plate in half, the width of each placement plate unit is reduced to half of the original width, while the plant is still placed on the upper part of the first support plate of each placement plate. The plants on adjacent placement plates have a larger growth space due to the existence of gaps, and the air circulation is also improved. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0020] like Figure 1 As shown, the fruit tree seedling breeding spacing adjustment structure provided by the present invention is used for the breeding and cultivation of fruit tree seedlings. It can flexibly adjust the seedling spacing according to the size of the plant during the seedling growth process. Specifically, it includes four parts: seedbed frame 10, support frame 20, seedling board 30, and drive part 40 for driving the seedling board 30 to slide on the support frame 20.

[0021] Specifically, such as Figure 1-6 As shown, the seedbed frame 10 includes a support 11. The lower end of the support 11 is provided with multiple legs 111 located in the vertical direction. Multiple crossbeams 112 are fixedly installed on the upper end of each leg 111. The crossbeams 112 are made of angle steel or square tube and extend horizontally along the length of the support 11. A rectangular frame 12 is fixedly installed on its upper end and is arranged around the four edges of the support 11. It is used to circumferentially block and limit the seedlings placed on the seedling board 30 in the horizontal direction to prevent the seedlings from slipping off the edge of the seedbed. A gap is maintained between its inner edge and the edge of the seedling board 30 for the seedling board 30 to slide.

[0022] Please see as follows Figure 1-5 As shown, the support frame 20 is horizontally fixedly installed on the upper end of the crossbeam 112, including a cross frame 21. The cross frame 21 is a cross-shaped grid frame welded from multiple mutually perpendicular channel steels 211. The cross-shaped grid frame is composed of multiple longitudinal channel steels arranged parallel to the long axis of the support 11 and multiple transverse channel steels arranged parallel to the short axis of the support 11, located in the same horizontal plane. The longitudinal channel steels and transverse channel steels intersect each other perpendicularly and are fixedly connected and connected at the intersection by welding to form a grid-like cross-shaped grid frame.

[0023] Each channel steel 211 has a groove 22 in the middle. The cross-section of the groove 22 is a groove shape with an open top. The opening width of the groove 22 is adapted to the outer diameter of the short column 32 described below. The short column 32 is located in the groove 22 and can slide freely inside the groove 22.

[0024] The spacing between adjacent longitudinal channel steels is the same as the spacing between adjacent transverse channel steels, thus forming a uniform grid so that the short columns 32 of the seedling board 30 can be regularly arranged in the chute 22.

[0025] On the other hand, the seedling board 30 includes multiple placement board units 31, such as Figure 2-3 As shown, each placement plate 31 unit is arranged side by side on the upper end of the support frame 20 along the long axis of the bracket 11. Each placement plate 31 is formed by multiple independent support plates hinged together end to end. The support plates are provided with through holes for water to pass through, so as to facilitate the flow of excess water and prevent water accumulation on the surface of the seedling plate 30.

[0026] In this embodiment, each placement plate 31 unit includes two support plates, namely a first support plate 311 and a second support plate 312. The first support plate 311 and the second support plate 312 are hinged to each other, so the second support plate 312 can rotate and fold relative to the first support plate 311 in the horizontal plane.

[0027] The first support plate 311 and the second support plate 312 have the same structural specifications. They are both composed of wire mesh and structural frame. The edge of the wire mesh is fixedly installed on the inner side of the structural frame, and the mesh of the wire mesh forms through holes for water to pass through.

[0028] A short post 32 is installed near the four corners of the lower end of the first support plate 311 and the second support plate 312. The short posts 32 extend vertically downward. As mentioned above, the spacing between the short posts 32 at the lower end of the placement plate 31 is the same as the spacing between the adjacent sliding grooves 22 in the cross frame 21. Each short post 32 is placed in the sliding groove 22 of the cross frame 21. The outer diameter of the short post 32 is adapted to the groove width of the sliding groove 22, so that the short post 32 can support the placement plate 31 to slide smoothly in the sliding groove 22.

[0029] Please continue reading. Figure 1 , Figure 6-7 The drive unit 40 is used to drive the seedling board 30 to slide on the support frame 20 and is set parallel to the short axis direction of the seedbed frame 10.

[0030] The drive unit 40 includes a sleeve 41 fixedly installed at the lower end of the crossbeam 112. The sleeve 41 is a cylindrical structure located in the horizontal plane, and its direction is located in the direction of the short axis of the seedbed frame 10. The inside of the sleeve 41 is hollow, and both ends are closed by end caps. A lead screw 44 is rotatably installed inside the sleeve 41. Both ends of the lead screw 44 are rotatably installed on the end caps of the sleeve 41 by bearings.

[0031] One end of the lead screw 44 extends out of the end of the sleeve 41 and is fixedly mounted with a handwheel 441. A slider 42 is threadedly mounted on the outer side of the lead screw 44. The outer wall of the slider 42 slides in fit with the inner wall of the sleeve 41. A connecting component is mounted on the sleeve 41 so that the slider 42 can only move along the axial direction of the sleeve 41 when the lead screw 44 rotates and cannot rotate with the lead screw 44.

[0032] The connecting assembly includes a stop 421 fixedly installed on the upper end of the slider 42. The upper end wall of the sleeve 41 has a slot 45 opened along the axial direction. The slot 45 extends along the length direction of the sleeve 41, and its length is the same as the width of the first support plate 311 or the second support plate. The stop 421 passes vertically upward through the slot 45 opened at the upper end of the sleeve 41, and its top is located at the lower end of the placement plate 31.

[0033] A connecting block 43 corresponding to the position of the stop block 421 is vertically fixedly installed on the lower end face of the placement plate 31. The connecting block 43 is fixedly installed on the lower end face of the first support plate 311 at the position corresponding to the stop block 421.

[0034] The rotation of the handwheel 441 drives the lead screw 44 to rotate. The lead screw 44 drives the slider 42 to move along the axial direction of the sleeve 41 through the threaded engagement. When the slider 42 moves towards the handwheel 441, the stop block 421 moves synchronously with the slider 42. The top of the stop block 421 abuts against the side wall of the connecting block 43, thereby pushing the connecting block 43 and the placement plate 31 fixed thereto to move together. When the placement plate 31 moves, the short column 32 at its lower end slides along the groove 22 of the cross frame 21 to provide guidance and support for the placement plate 31.

[0035] like Figure 2 As shown, in the first state, the first support plate 311 and the second support plate 312 of each placement plate 31 unit are fully unfolded, that is, the first support plate 311 and the second support plate 312 are unfolded to the same position in the horizontal plane, and the two support plates together form a complete rectangular placement surface.

[0036] The fruit tree seedlings to be cultivated are placed on the upper surface of each placement board 31. Since the placement board 31 is fully covered on the upper part of the support frame 20, the seedling board 30 forms a continuous and flat bearing surface, which can support a large number of seedlings over a large area. In the early stage of seedling growth, the individual plants are small and there is no problem of shading or crowding between them. Therefore, the dense arrangement method of Form 1 can maximize the use of the cultivation area of ​​the seedbed.

[0037] Example 2: After the fruit tree seedlings have grown for a period of time, the crown width and root system range of the plants have increased. Problems such as overlapping leaves, mutual shading and root competition between adjacent plants have begun to appear. At this time, it is necessary to increase the spacing between plants to ensure the normal growth of each plant. The structure of this embodiment is basically the same as that of embodiment one, except that the folding state of the placement plate 31 is different.

[0038] Based on Form 1, the second support plate 312 is folded towards the first support plate 311. The second support plate 312 rotates 180° around the hinge axis and is folded over the first support plate 311 from its original flat unfolded state. Since the first support plate 311 and the second support plate 312 have the same specifications, the second support plate 312 is completely located above the first support plate 311 after being folded, and the two overlap in the vertical direction.

[0039] After the second support plate 312 is folded in half, the overall length of each placement plate 31 unit is reduced by the width of one support plate, thereby forming a gap between adjacent placement plates 31 that is equal in width to the second support plate 312, and the bearing surface at the upper end of the seedling plate 30 is divided into multiple independent bearing areas that are spaced apart from each other.

[0040] By folding the second support plate 312 of each placement plate 31 in half, the width of each placement plate 31 unit is reduced to half of its original width, while the plant is still placed on the top of the first support plate 311 of each placement plate 31. The plants on adjacent placement plates 31 gain more growing space due to the gaps, and air circulation is also improved.

[0041] Example 3: This embodiment is a further adjustment based on Embodiment 2.

[0042] As described above, during the operation of the drive unit 40, under the push of the drive unit 40, the placement plate 31 undergoes a displacement of the width of either the support plate 311 or the second support plate 312 along the short axis direction. Simultaneously, the drive unit 40 is installed at intervals at the lower end of the seedling plate 30. Figure 2 As shown, the operator can operate different drive units 40 to make adjacent placement plates 31 have different displacements in the short axis direction, so as to achieve the effect of adjacent placement plates 31 intersecting each other.

[0043] After the adjacent placement boards 31 are staggered, each placement board 31 is staggered in the short axis direction of the seedbed frame 10. The two adjacent placement boards 31 are not on the same horizontal straight line. The staggered arrangement increases the distance between the plants originally located on the adjacent placement boards 31 in both the longitudinal and horizontal directions, and the plants have more room to grow. Compared with the second form, this arrangement provides better growth space and light conditions for each plant.

[0044] In the early stages of breeding, when the seedlings are small, intensive cultivation is carried out using Form 1 to maximize the utilization of the seedbed area. When the seedlings grow to a certain stage and the leaves begin to touch each other, the operator folds the second support plate 312 of each placement plate 31 above the first support plate 311, switching to Form 2, so that gaps are formed between adjacent placement plates 31, increasing the spacing between plants. When the seedlings continue to grow and the spacing of Form 2 can no longer meet the requirements, the operator operates each drive unit 40 to make the adjacent placement plates 31 intersect each other in the short axis direction, switching to Form 3, further increasing the spacing between plants in the longitudinal and transverse directions, until the seedlings reach the transplanting standard.

[0045] Example 4: The support frame 20 includes a cross frame 21, which is a star-shaped frame formed by welding multiple channel steels 211 that are spaced 45° apart. The channel steels 211 include multiple channel steels extending in four directions: 0°, 45°, 90°, and 135°. Each channel steel is welded and fixed at the central intersection point to form a star-shaped grid. The short column 32 at the lower end of the placement plate 31 is located in the sliding groove 22 of the cross frame 21 and can slide along the sliding groove 22. The star-shaped frame structure allows the placement plate 31 to have more sliding direction options on the support frame 20. The spacing between seedlings can be adjusted in different directions according to actual needs to adapt to fruit tree seedlings with different growth forms.

[0046] Working principle: By setting the seedling plate 30 into multiple placement plate 31 units hinged together by the first support plate 311 and the second support plate 312, and cooperating with the sliding groove 22 of the support frame 20 and the screw transmission mechanism of the drive unit 40, multi-level adjustment of the seedling spacing is realized. In the first mode, the placement plate 31 is fully unfolded and spread on the support frame 20 to achieve dense cultivation. In the second mode, the second support plate 312 is folded over the first support plate 311, and gaps are formed between adjacent placement plates 31. In the third mode, each placement plate 31 slides alternately along the short axis direction under the drive of the drive unit 40, further increasing the plant spacing.

[0047] The above embodiments are merely one of the preferred embodiments of the present invention and should not be used to limit the scope of protection of the present invention. Any modifications or refinements made to the main design concept and spirit of the present invention that are not of substantial significance, but solve the same technical problem as the present invention, should be included within the scope of protection of the present invention.
