Description

Technical Field

[0001] This utility model relates to the field of agricultural planting technology, and in particular to an adjustable agricultural planting rack for agricultural planting. Background Technology

[0002] Adjustable agricultural planting racks are facilities and equipment used in agricultural planting. They are usually made of materials such as metal and plastic. Growers can flexibly place them in a limited space by adjusting the height, width, or spacing between layers according to the size and shape of the planting site, so as to maximize the use of space, plant more crops per unit area of ​​land, and improve land utilization.

[0003] Chinese Patent CN219593155U discloses an adjustable agricultural planting rack, belonging to the field of agricultural planting rack technology. It includes a base plate with four vertically fixed support rods arranged in a rectangular pattern on the upper surface. Multiple planting layers are arranged between the four support rods. Adjustable gears are rotatably mounted at both ends of the opposite sidewalls of each planting layer. Multiple teeth are fixed along the length of the support rod sidewalls, meshing with the adjusting gears. A connecting rod is coaxially fixed between two adjusting gears at the same end. A worm gear is coaxially fixed on the connecting rod, meshing with a worm, and a drive rod is coaxially fixed with the worm. This configuration, by setting adjustable gears on the planting layers and arranging teeth on the support rods to mesh with the adjusting gears, and by rotating the drive rod, achieves the height adjustment effect of the planting layers. Simultaneous height adjustment at both ends of the planting layer is achieved by rotating the drive rod, making operation simpler and improving adjustment efficiency and practicality.

[0004] The aforementioned patent achieves height adjustment of the planting layer by adjusting multiple components such as gears, teeth, connecting rods, worm gears, worms, and drive rods. With many transmission components, wear and loosening between components may easily occur during long-term use, leading to a relatively high probability of failure and increased maintenance costs. On the other hand, the uniformity of light is poor, and the upper planting layer may cause more shading to the crops in the lower planting layer, affecting the uniformity of light.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art.

[0034] like Figure 1 and Figure 5 As shown in the figure, this embodiment provides an adjustable agricultural planting frame for agricultural planting, including a base plate 1, with columns 2 fixedly connected to the top four corners of the base plate 1, and casters 3 fixedly connected to the bottom four corners of the base plate 1. The base plate 1 includes an adjustment mechanism 4 for lifting and lowering, a first limiting mechanism 8 for limiting and a second limiting mechanism 9 for limiting.

[0035] A handwheel 41 is provided on one side of the column 2. A transmission rod 42 is fixedly sleeved inside the handwheel 41. The transmission rod 42 is rotatably connected to the inside of the column 2 on the same side. A first bevel gear 43 is fixedly sleeved on the outer surface of both ends of the column 2. A second bevel gear 44 is meshed on the outer surface of the first bevel gear 43. A double-acting screw 45 shaft is fixedly sleeved inside the second bevel gear 44. A screw sleeve 46 is threaded to the outer surface of both ends of the double-acting screw 45. A first linkage rod 47 is movably connected to both sides of the screw sleeve 46. A convex block 48 is movably connected to the top of the first linkage rod 47. The upper part of the convex block 48 is slidably connected to the inner wall of the slide frame 49. A fixed drawer 6 is fixedly connected to one side of the slide frame 49.

[0036] Specifically, when the height of the fixed drawer 6 needs to be adjusted, first turn the handwheel 41. The handwheel 41 drives the first bevel gear 43 to rotate inside the column 2 via the transmission rod 42. The first bevel gear 43 drives the second bevel gear 44 to rotate. The rotation of the second bevel gear 44 causes the double-acting screw 45 to rotate. When the double-acting screw 45 rotates, the threaded sleeves 46 at both ends will move in opposite directions along the double-acting screw 45. The first linkage rod 47 will move along with the threaded sleeves 46. The movement of the first linkage rod 47 will push the convex block 48 to slide in the slide frame 49, and at the same time drive the slide frame 49 to rise, thereby raising the fixed drawer 6 as well, thus realizing the adjustment of the height of the fixed drawer 6. It can flexibly utilize space according to the needs of different crops. This design is easy to operate, greatly improves work efficiency, and saves manpower and time costs.

[0037] A first connecting block 410 is fixedly connected to the top of the convex block 48. A second linkage rod 411 is fixedly connected to both sides of the first connecting block 410. A second connecting block 412 is fixedly connected to the top of the second linkage rod 411. A top plate 413 is movably connected to the top of the second connecting block 412. Both ends of the top plate 413 are slidably connected to the inner side of the column 2. A connecting plate 414 is fixedly connected to one side of the top plate 413. A top planting tray 7 is slidably connected to the opposite side of the connecting plate 414.

[0038] Specifically, when the convex block 48 slides within the sliding frame 49, it causes the first connecting block 410 to move together. The movement of the first connecting block 410 causes the second linkage rod 411 to move. The movement of the second linkage rod 411 causes the second connecting block 412 to move upward. The second connecting block 412 causes the top plate 413 to rise inside the column 2. The rise of the top plate 413 causes the connecting plate 414 to rise synchronously. As the connecting plate 414 rises, the top planting tray 7 also moves upward, thereby realizing the adjustment of the height of the top planting tray 7. This design reduces the difficulty of operation, saves manpower, and improves the efficiency of agricultural operations.

[0039] like Figure 1 and Figure 5As shown, a bottom planting tray 5 is slidably connected inside the base plate 1. A locking block 94 is fixedly connected to one side of the bottom planting tray 5. A second fixing block 91 is fixedly connected to one side of the base plate 1. A second pull rod 92 is slidably connected inside the second fixing block 91. A second spring 93 is sleeved on the outer surface of the second pull rod 92. One end of the second fixing block 91 passes through the inside of the second fixing block 91 and is fitted into the groove inside the locking block 94.

[0040] Specifically, when it is necessary to adapt the bottom planting tray 5 to different light conditions, firstly, a pulling force is applied to the second pull rod 92, which slides inside the second fixing block 91. At this time, the second spring 93 is stretched. As the second pull rod 92 moves outward, one end gradually comes out of the groove inside the locking block 94, thereby releasing the locking block 94. Then, the bottom planting tray 5 is pulled out. With the cooperation of the dovetail tenons on both sides and the groove inside the base plate 1, the bottom planting tray 5 can be pulled out up to two-thirds, so that the crops in the bottom planting tray 5 that are blocked by the fixing tray 6 can absorb light, increasing the uniformity of light and preventing the crops from growing poorly due to uneven light.

[0041] The top plate 413 is fixedly connected to the top of the first fixing block 81. The first fixing block 81 is slidably connected to the first pull rod 82. The outer surface of the first pull rod 82 is fitted with a first spring 83. One end of the first pull rod 82 passes through the inside of the first fixing block 81 and is fitted into the groove on one side of the top planting tray 7.

[0042] Specifically, when the fixed tray 6 needs to adapt to different light conditions, an outward pulling force is first applied to the first pull rod 82. During the pulling of the first pull rod 82, the first spring 83 is stretched. As the first pull rod 82 slides outward, one end of it disengages from the slot on one side of the top planting tray 7, thereby releasing the lock on the top planting tray 7. Then, the top planting tray 7 is slid along the connecting plate 414, making it slide in the opposite direction to the bottom planting tray 5. When the top planting tray 7 is pushed to the appropriate position, the first pull rod 82 is released. Under the elastic restoring force of the first spring 83, one end of the first pull rod 82 is re-inserted into another slot on one side of the top planting tray 7, thereby locking the top planting tray 7 and fixing it stably on the connecting plate 414. This prevents the top planting tray 7 from accidentally sliding due to shaking or other reasons. At this time, the crops in the fixed tray 6 that are blocked by the top planting tray 7 can absorb light, increasing the uniformity of light and preventing the crops from growing poorly due to uneven light.

[0043] The bidirectional lead screw 45 is rotatably connected to the inside of the column 2, and both ends of the slide frame 49 are slidably connected to the inside of the column 2.

[0044] Specifically, the column 2 provides a clear motion track for the bidirectional lead screw 45 and the slide frame 49. On the one hand, it provides stable support for the rotation of the bidirectional lead screw 45, reduces the shaking and offset when the lead screw rotates, and ensures the accuracy and stability of the transmission. On the other hand, it makes the slide frame 49 more stable during the up and down sliding process, and can better drive the fixed drawer 6 to rise and fall, avoiding damage to crops due to shaking.

[0045] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
