Description

Technical Field

[0001] This utility model relates to the agricultural field, and in particular to a novel soilless cultivation device for agricultural planting. Background Technology

[0002] An existing patent (publication number: CN212544978U) proposes a mobile soilless cultivation agricultural planting rack, including a base with locking casters installed on the bottom surface of the base. A bracket is welded to the upper surface of the base, and several support blocks are evenly fixed on the inner walls of both sides of the bracket. A planting tray is installed on the support blocks, and a slurry hole is opened at one end of the planting tray. The top end of the slurry pipe is fixedly connected to the slurry hole, and the bottom end of the slurry pipe extends into the planting tray below. A filter frame is welded to the upper surface of the base, and a vertical filter screen is fixedly installed in the middle of the filter frame by bolts. A water pump is fixedly installed on one side of the bottom of the filter frame by bolts. The output end of the water pump is fixedly connected to one end of a circulation pipe, and the other end of the circulation pipe extends into the planting tray at the top of the bracket. However, in this device, "the support block and pin clamp and fix one end of the planting tray to the support block", and the height of the planting tray is fixed. It is impossible to adjust the longitudinal spacing between the planting trays according to the actual growth of the crops. If the spacing is too small, it will cause seedling crushing, or if the spacing is too large, it will cause waste of frame space, which has drawbacks. Summary of the Invention

[0003] This invention addresses the aforementioned shortcomings of existing technologies by providing a novel soilless cultivation device that allows for flexible adjustment of the spacing between cultivation boxes based on the growth habits of different crop seedlings and actual planting needs. Through reasonable spacing, it ensures that each layer of seedlings receives sufficient growth space and light, promoting healthy seedling growth, improving the quality of soilless cultivation in agriculture, and preventing seedling suffocation due to excessively small spacing or waste of shelf space due to excessively large spacing.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A novel soilless cultivation device for agricultural planting includes a cultivation frame, a cultivation box, a cultivation board, a support plate, a shaft, a rotating sleeve, and a locking sleeve. The cultivation box has a support strip on its inner side, which connects to the cultivation board. The cultivation board has multiple cultivation holes. The cultivation box has a placement plate on its outer side, which connects to the support plate. The support plate has a protruding rod, and the placement plate has a protruding rod groove. The protruding rod and the groove are compatible, and the protruding rod connects to the groove. The support plate has positioning sleeves on both sides. An mounting plate is located outside the positioning sleeves, connecting to the outside of a bearing. A threaded rod is connected inside the bearing, and a knob is located at the outer end of the threaded rod, fitting against the mounting plate. The inner end of the threaded rod is connected to a locking sleeve via a thread, fitting against the outer side of the positioning sleeve. The inner side of the positioning sleeve fits against the rotating sleeve, and a gear disc is located outside the rotating sleeve.

[0006] The shaft of this invention passes sequentially through a locking sleeve, a positioning support sleeve, and a rotating sleeve. The rotating sleeve has multiple control protrusions, and the shaft has multiple control grooves. The control protrusions are adapted to the control grooves and are connected to them. The outer end of the shaft has multiple locking slots, and the locking sleeve has locking blocks that are adapted to the locking slots and are connected to them. The inner end of the shaft has a rotating rod that passes through the positioning support sleeve. The rotating rod has a connecting rod with a connecting plate, and a screw passes through the connecting plate. Nuts are threaded to both ends of the screw. Beneficial effects

[0007] This utility model features a separate design for the cultivation box, cultivation board, and support board, facilitating the addition and replacement of nutrient solution and seedling transplanting. It is easy to operate and improves the efficiency of soilless cultivation in agriculture. Furthermore, the spacing between the cultivation boxes can be flexibly adjusted according to the growth habits of different crops and actual planting needs. A reasonable spacing ensures that each layer of seedlings receives sufficient growth space and light, promoting healthy seedling growth, improving the quality of soilless cultivation in agriculture, and preventing seedling suffocation due to excessively small spacing or wasted frame space due to excessively large spacing.

[0008] This utility model relates to a threaded rod that is positioned between the thread and the locking sleeve. When the threaded rod is rotated by turning the knob, the locking sleeve moves linearly. When the locking sleeve moves to the point where the locking block is embedded in the locking groove, it increases the positioning fulcrum of the shaft. At this point, the rotating sleeve and gear disc are synchronously braked and cannot rotate, thus fixing the support height of the support plate. When the locking sleeve is moved to the point where the locking block is completely disengaged from the locking groove by turning the knob in the opposite direction, the positioning fulcrum of the shaft disappears. At this point, the support height of the support plate can be freely adjusted by sliding the positioning sleeve, thereby meeting the growth needs of different crops in seedling cultivation or at different stages. Through reasonable cultivation space, it promotes healthy seedling growth while increasing the flexibility of the cultivation rack, expanding its application range and practical performance.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

[0018] Example 1:

[0019] A novel soilless cultivation device for agricultural planting includes a cultivation frame 01, a cultivation box 06, a cultivation board 07, a support plate 09, a shaft 15, a rotating sleeve 18, and a locking sleeve 24. The cultivation box 06 has a support strip 13 on its inner side, which connects to the cultivation board 07. The cultivation board 07 has multiple cultivation holes 08. The cultivation box 06 has a placement plate 10 on its outer side, which connects to the support plate 09. The support plate 09 has a protruding rod 11, and the placement plate 10 has a protruding rod groove 12. The protruding rod 11 is adapted to the protruding rod groove 12, and the protruding rod 11 is connected to the protruding rod groove 12. The support plate 09 has positioning sleeves 14 on both sides. The positioning sleeves 14 have mounting plates 30 on the outside. The mounting plates 30 are connected to the outside of the bearing 29. The bearing 29 is connected to the threaded rod 27. The outer end of the threaded rod 27 has a knob 28, which fits into the mounting plate 30. The inner end of the threaded rod 27 is connected to a locking sleeve 24 by a thread. The locking sleeve 24 fits into the outer side of the positioning sleeve 14. The positioning sleeve 14 is connected to the inner side of the positioning sleeve 14. The side-fitting rotating sleeve 18 has a gear disk 05 on its outside. The threaded rod 27 is positioned and connected to the locking sleeve 24 through the thread. When the threaded rod 27 is driven to rotate by rotating the knob 28, the locking sleeve 24 moves linearly. When the locking sleeve 24 moves to the point where the locking block 25 is embedded in the locking groove 26, the locking sleeve 24 can increase the positioning fulcrum of the shaft 15. At this time, the rotating sleeve 18 and the gear disk 05 are braked synchronously and cannot rotate, thus fixing the support height of the support plate 09. When the locking sleeve 24 is driven to move to the point where the locking block 25 is completely disengaged from the locking groove 26 by rotating the knob 28 in the opposite direction, the positioning fulcrum of the locking sleeve 24 on the shaft 15 disappears. At this time, the support height of the support plate 09 can be freely adjusted by sliding the positioning sleeve 14 to meet the growth needs of different crops in seedling or at different stages. Through reasonable cultivation space, it promotes healthy seedling growth and increases the flexibility of the cultivation rack 01, expanding its application range and practical performance.

[0020] Example 2:

[0021] The shaft 15 of this utility model passes sequentially through the locking sleeve 24, the positioning support sleeve 14, and the rotating sleeve 18. The rotating sleeve 18 has multiple control protrusions 16, and the shaft 15 has multiple control grooves 17. The control protrusions 16 are adapted to the control grooves 17 and are connected to the control grooves 17. The outer end of the shaft 15 has multiple locking grooves 26, and the locking sleeve 24 has a locking block 25. The locking block 25 is adapted to the locking grooves 26 and is connected to the locking grooves 26. The inner end of the shaft 15 has a rotating rod 19, which passes through the positioning support sleeve 14. The rotating rod 19 has a connecting rod 20, which has a connecting plate 21. A screw 22 passes through the connecting plate 21, and both ends of the screw 22 are connected to nuts 23 by threads.

[0022] Example 3:

[0023] The cultivation rack 01 of this utility model has multiple fixed columns 02, which pass through positioning support sleeves 14. The lower end of the fixed column 02 is connected to a fixed base plate 03. The fixed column 02 has a rack 04, which meshes with a gear disk 05. The gear disk 05 is connected to the rack 04. The cultivation box 06, cultivation board 07, and support plate 09 are all designed as separate units, which facilitates the addition and replacement of nutrient solution and the transplanting of seedlings. The operation is convenient and improves the efficiency of soilless cultivation in agriculture. At the same time, the layer spacing between cultivation boxes 06 can be flexibly adjusted according to the growth habits of different crop seedlings and actual planting needs. Through reasonable layer spacing, it is ensured that each layer of seedlings can obtain sufficient growth space and light, promote healthy seedling growth, improve the quality of soilless cultivation in agriculture, and prevent seedling suffocation due to excessively small layer spacing or waste of rack space due to excessively large layer spacing.

Then, embed the threaded rod 27 into the bearing 29 until the inner surface of the knob 28 fits against the mounting plate 30, and the inner end of the threaded rod 27 is inserted into the locking sleeve 24, and positioned and connected to it by threads. Then, the shaft 15 passes through the locking sleeve 24, the positioning support sleeve 14, and the rotating sleeve 18 in sequence until the locking block 25 corresponds to the locking groove 26. The rotating rod 19 passes through the positioning support sleeve 14, and the control protrusion 16 is embedded in the control groove 17. The two connecting plates 21 are fitted together. Finally, the screw 22 passes through the two connecting plates 21, and its two ends are connected to the nut 23 by threads. After the support plate 09 structure is assembled, it is placed into the cultivation rack 01. The fixing column 02 passes through the positioning support sleeve 14 and is fixedly connected to the fixing base plate 03. The gear disk 05 is meshed with the rack 04. Then, the support plate 09 is adjusted to a reasonable height, and the locking sleeve 24 is moved by rotating the knob 28.
