Description

Technical Field

[0001] The present application relates to the technical field of cultivation racks, and more specifically, to a height adjustment mechanism for a seedling cultivation rack. Background Art

[0002] Seedling cultivation is an important part of urban greening. Some seedlings are cultivated in the ground, and some are cultivated on cultivation racks. Cultivating seedlings in the ground requires a lot of land, and cultivation racks are generally multi-layer structures. Cultivating on cultivation racks can save a lot of land.

[0003] The document with prior art announcement number CN219812649U provides a height adjustment mechanism for a seedling cultivation rack. Through the lifting mechanism installed at the bottom of the fixed block, a bidirectional motor drives the connected rotating rod to rotate. The rotation of the rotating rod can drive the wound steel rope to loosen or tighten downward. During the loosening or tightening process of the steel rope, the tray connected to the bottom is driven to move up and down, adjusting the distance between the tray and the first support rod to prevent the seedlings from being squeezed during the cultivation and growth process, affecting the growth of the seedlings.

[0004] Although the device has many beneficial effects, the following problems still exist: after the height of the tray is adjusted, it is difficult to adjust the lateral displacement of the tray, so that the trays block each other, making the production space of seedlings still small. In view of this, we propose a height adjustment mechanism for the seedling cultivation rack. Utility Model Content

[0005] The embodiment of the present application solves the technical problem in the prior art that after the height of the tray is adjusted, it is difficult to adjust the lateral displacement of the tray, so that the trays block each other and the production space for seedlings is still small. After adjusting the height of the two cultivation trays, the cultivation trays can be adjusted for lateral displacement, so that the two cultivation trays are moved to a mutually staggered position, thereby facilitating the technical effect of further expanding the growth space of the seedlings.

[0006] The embodiment of the present application provides a height adjustment mechanism for a seedling cultivation rack, comprising: a support frame;

[0007] The top of the support frame is connected to two horizontal plates through a screw transmission member, and the top of the horizontal plate is connected to a cultivation tray through a displacement mechanism, so as to facilitate displacement of the cultivation tray;

[0008] The displacement mechanism includes a support plate, which is slidably connected to the top of the cross plate, and the cultivation plate is located on the top of the support plate. Both sides of the top of the support plate are fixedly connected with mounting frames, and a slide plate is slidably connected in the mounting frame. An opening is opened on one side of the mounting frame, and one side of the slide plate is fixedly connected with a cross bar, and one end of the cross bar is fixedly connected with a positioning plate. Two positioning blocks are fixedly connected to both sides of the top of the cross plate, thereby facilitating the expansion of the growth space of the seedlings.

[0009] By adopting the above technical solution and setting up a displacement mechanism, after adjusting the height of the two cultivation trays, the cultivation trays can be adjusted for lateral displacement, so that the two cultivation trays are moved to mutually staggered positions, thereby facilitating further expansion of the growth space of the seedlings.

[0010] Optionally, both sides of the top of the horizontal plate are provided with sliding grooves, and a slider is slidably connected in the sliding groove. The top of the slider is fixedly connected to the bottom of the support plate, so that the support plate can move along the direction of the sliding groove.

[0011] By adopting the above technical solution and providing the slide groove and the slider, when the support plate moves, the slider can be driven to move in the slide groove, so that the support plate can move horizontally along the direction of the slide groove.

[0012] Optionally, guide rods are fixedly connected to both sides of the installation frame, and the slide plate is slidably sleeved on the outside of the guide rods, thereby ensuring that the slide plate will not fall off from the installation frame.

[0013] By adopting the above technical solution and providing the guide rod, the slide plate can be moved in the installation frame along the direction of the guide rod, and the slide plate is blocked so that the slide plate will not fall out of the installation frame.

[0014] Optionally, a pull rod is slidably connected to the other side of the installation frame, one end of the pull rod is fixedly connected to the side of the skateboard away from the cross bar, the side of the skateboard away from the cross bar is fixedly connected to two springs, one end of the spring is fixedly connected to one side of the inner wall of the installation frame, and the spring is sleeved on the outside of the guide rod to prevent the skateboard from moving at will.

[0015] By adopting the above technical solution and setting a spring, when the slide plate moves toward the direction close to the pull rod, the spring will be squeezed, so that there is resistance to the movement of the slide plate, thereby preventing the slide plate, the slide rod and the positioning plate from moving at will.

[0016] Optionally, a connecting plate is fixedly connected to one side of the cultivation tray, and the connecting plate is connected to the support plate via a threaded rod, so that the staff can easily disassemble and assemble the cultivation tray.

[0017] By adopting the above technical solution, by setting up a connecting plate and a threaded rod, after the staff unscrews the threaded rod, the connecting plate can be separated from the support plate, thereby facilitating the removal of the cultivation tray from the support frame, and then facilitating the staff to disassemble and assemble the cultivation tray.

[0018] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0019] 1. By setting up a displacement mechanism, after adjusting the height of the two cultivation trays, the cultivation trays can be adjusted for lateral displacement, so that the two cultivation trays are moved to mutually offset positions, thereby facilitating further expansion of the growth space of the seedlings.

[0020] 2. By setting the spring, when the slide plate moves toward the direction close to the pull rod, the spring will be squeezed, so that there is resistance to the movement of the slide plate, thereby preventing the slide plate, the slide rod and the positioning plate from moving at will.

[0021] 3. By setting up the connecting plate and the threaded rod, after the staff unscrews the threaded rod, the connecting plate can be separated from the support plate, thereby facilitating the removal of the cultivation tray from the support frame, and further facilitating the staff to disassemble and assemble the cultivation tray.

[0026] The present application is further described in detail below in conjunction with the accompanying drawings.

[0027] Reference Figure 1 and Figure 2 , the embodiment of the present application discloses a height adjustment mechanism of a seedling cultivation rack. The height adjustment mechanism of the seedling cultivation rack comprises: a support frame 1;

[0028] The top of the support frame 1 is connected to two horizontal plates 4 through a screw transmission member 2, and the top of the horizontal plate 4 is connected to a cultivation tray 5 through a displacement mechanism 3, so as to facilitate displacement of the cultivation tray 5;

[0029] The displacement mechanism 3 includes a support plate 31, which is slidably connected to the top of the cross plate 4, and the cultivation tray 5 is located at the top of the support plate 31. Both sides of the top of the support plate 31 are fixedly connected with mounting frames 34, and a slide plate 35 is slidably connected in the mounting frame 34. An opening is opened on one side of the mounting frame 34, and a cross bar 36 is fixedly connected to one side of the slide plate 35. One end of the cross bar 36 is fixedly connected to a positioning plate 37. Two positioning blocks 33 are fixedly connected to both sides of the top of the cross plate 4, so as to facilitate the staff to move the cultivation tray 5 horizontally and expand the growth space of the seedlings.

[0030] Reference Figure 1 The screw transmission part 2 includes a motor, a bidirectional screw, a group of sliding rods, two groups of screw sleeves and two groups of sliding sleeves. The sliding rod is fixedly connected to the top of the support frame 1, the sliding sleeve is slidingly sleeved on the outside of the sliding rod, and the screw sleeve is threadedly sleeved on the outside of the bidirectional screw rod. A slot is opened through the top of the support frame 1, and a bearing is installed in the slot. The bidirectional screw rod is located in the bearing, and the motor is installed at the bottom of the support frame 1. The top of the motor output shaft is fixedly connected to the bottom end of the bidirectional screw rod, and the motor is connected to an external controller and a power supply. It is a prior art and will not be described here. The two groups of screw sleeves are respectively fixedly connected to the two cross plates 4, and the two groups of sliding sleeves are respectively fixedly connected to the two cross plates 4, so that when the motor drives the bidirectional screw rod to rotate, the two screw sleeves can be driven to move in the direction of approaching or moving away from each other. The movement of the screw sleeve can drive the cross plate 4 to move, so that the cross plate 4 can move away from or close to each other, thereby facilitating the adjustment of the height of the cross plate 4.

[0031] Reference Figure 2 and Figure 3 Both sides of the top of the horizontal plate 4 are provided with slide grooves, in which a slider 32 is slidably connected, and the top of the slider 32 is fixedly connected to the bottom of the support plate 31, so that the support plate 31 can move along the direction of the slide groove.

[0032] Reference Figure 2 and Figure 3 The cross-sections of the slide groove and the slider 32 are both in a convex shape, thereby preventing the slider 32 from moving vertically in the slide groove.

[0033] Reference Figure 2 and Figure 3 The cross section of the positioning plate 37 is U-shaped, so that after the positioning plate 37 is sleeved on the outside of the positioning block 33, the support plate 31 cannot move.

[0034] Reference Figure 3Guide rods 38 are fixedly connected to both sides of the installation frame 34 , and the slide plate 35 is slidably sleeved on the outside of the guide rods 38 , thereby ensuring that the slide plate 35 will not be separated from the installation frame 34 .

[0035] Reference Figure 3 Two springs 39 are fixedly connected to the side of the slide plate 35 away from the cross bar 36. One end of the spring 39 is fixedly connected to one side of the inner wall of the installation frame 34. The spring 39 is sleeved on the outside of the guide rod 38, so as to prevent the slide plate 35 from moving at will.

[0036] Reference Figure 3 A pull rod 6 is slidably connected to the other side of the installation frame 34, and one end of the pull rod 6 is fixedly connected to the side of the slide plate 35 away from the cross bar 36, so that it is convenient for the staff to pull the slide plate 35 without the need for the staff to reach into the installation frame 34 to pull the slide plate 35, thereby preventing the staff's hands from being scratched or pinched.

[0037] Reference Figure 3 The cross section of the pull rod 6 is T-shaped, which is convenient for the staff to hold the pull rod 6 with their hands.

[0038] Reference Figure 1 and Figure 2 A connecting plate 7 is fixedly connected to one side of the cultivation tray 5, and the connecting plate 7 is connected to the support plate 31 through a threaded rod 8, which is convenient for staff to disassemble and assemble the cultivation tray 5.

[0039] The implementation principle of the height adjustment mechanism of the seedling cultivation rack in the embodiment of the present application is as follows: when it is necessary to adjust the height of the cultivation tray 5, the staff can drive the two cross plates 4 to move in the direction of approaching or moving away from each other through the screw transmission member 2, and the movement of the cross plate 4 can drive the support plate 31 and the cultivation tray 5 to move, thereby adjusting the height of the two cultivation trays 5. When the height adjustment of the cultivation tray 5 is completed, the staff can pull the pull rod 6 to drive the slide plate 35 to move, and the movement of the slide plate 35 can squeeze the spring 39 and drive the cross bar 36 to move. The movement of the cross bar 36 can drive the positioning plate 37 to move, so that the positioning plate 37 is separated from one of the positioning blocks 33, and then the support plate 31 is moved. The movement of the support plate 31 can drive the slider 32 and the cultivation tray 5 to move. When the cultivation tray 5 moves to the specified position, the pull rod 6 is released, so that the squeezed spring 39 is reset and rebounded, driving the slide plate 35, the cross bar 36 and the positioning plate 37 to move in the direction close to the other positioning block 33, until the positioning plate 37 is inserted on the outside of the other positioning block 33, so that the two cultivation trays 5 can be laterally moved and adjusted to a misaligned state.
