Description

Technical Field

[0001] This utility model relates to the field of cultivation rack technology, specifically to a multi-layer cultivation rack. Background Technology

[0002] In the field of modern agricultural facility planting, greenhouse cultivation, as an important production method, plays a key role in increasing crop yields and realizing off-season planting.

[0003] Patent CN218163813U discloses a three-dimensional cultivation rack, including a three-dimensional cultivation rack body and edible fungus cultivation bags, as well as a top plate, side support legs, a winding roller, and a dark shade cloth. Two sets of side support legs are symmetrically fixed to the bottom surface of the top plate in a figure-eight shape. The three-dimensional cultivation rack body includes cultivation boards, support platforms, and side baffles. Each of the two support platforms has an inclined surface on its opposite side. A water trough is formed on the top surface of the cultivation board, located inside the two support platforms. The dark shade cloth is rolled up on the winding roller. This utility model's three-dimensional cultivation rack, by mounting the three-dimensional cultivation rack body with side support legs distributed in a figure-eight shape, can ensure that the fruiting bodies of *Auricularia auricula-judae* at all heights can receive sufficient sunlight. However, in the above solution, the distance between each cultivation board is fixed. When the crops planted on each cultivation board are at different growth stages and thus different heights, it is easy for some cultivation boards to have redundant growth space while other cultivation boards have insufficient growth space. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies that cannot flexibly adjust the growth space of crops, and to provide a multi-layer cultivation rack that can flexibly adjust the growth space of each layer of crops according to the specific growth conditions of each layer.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A multi-layer cultivation rack is provided, including a frame, support plates, cultivation troughs and a lifting mechanism. The lifting mechanism is installed on the frame, a plurality of support plates are connected to the lifting mechanism, and the cultivation troughs are installed on the support plates.

[0006] This utility model discloses a multi-layer cultivation rack in which cultivation troughs are installed on support plates, and crop seedlings are planted in the cultivation troughs. The rack supports the support plates and cultivation troughs. As the crops grow, the support plates are raised or lowered by a lifting mechanism according to the growth of the crops in the cultivation troughs on each support plate. This adjusts the distance between the cultivation troughs on each support plate, ensuring that the crops in each cultivation trough have sufficient growing space, good light and ventilation, and effectively improving the spatial adaptability of crops at different growth stages.

[0007] Furthermore, the lifting mechanism includes multiple sets of telescopic rods, which are fixedly installed on the frame. The output ends of the multiple sets of telescopic rods are respectively fixedly connected to multiple support plates, and the telescopic rods extend or retract vertically. When the lifting mechanism is working, the telescopic rods extend or retract, and the output ends of the telescopic rods rise or fall, causing the support plates fixedly connected to the output ends of the telescopic rods to rise or fall, thereby adjusting the growing space for the crops.

[0008] Furthermore, the cultivation trough is fixedly installed on the side of the support plate, and the projected area of ​​the multiple support plates increases sequentially from top to bottom in the horizontal direction. The cultivation trough is installed on the side of the support plate, and the area of ​​the support plate increases sequentially from top to bottom, ensuring that the cultivation trough is not blocked by the support plate or other cultivation troughs, thus ensuring that the crops receive sufficient sunlight.

[0009] Furthermore, it also includes a water tank, which is disposed on the top surface of the support plate. A water supply pipe is connected to the water tank and is connected to the cultivation trough. Water or nutrient solution is injected into the water tank, and the water or nutrient solution is then supplied to the cultivation trough through the water supply pipe to irrigate the crops.

[0010] Furthermore, the water supply pipeline includes a main pipe and multiple branch pipes. The main pipe is connected to the water tank, and the multiple branch pipes are connected to the main pipe. The outlets of the branch pipes are located above the cultivation trough, and the multiple branch pipes are evenly arranged along the length of the cultivation trough. The even arrangement of the multiple branch pipes along the length of the cultivation trough allows water or nutrient solution to flow evenly into different areas of the cultivation trough, ensuring that the crops receive uniform irrigation.

[0011] Furthermore, the bottom of the cultivation trough is provided with several drainage holes. The drainage holes can drain the water in the cultivation trough in a timely manner, preventing excessive water accumulation from causing the crops to rot due to lack of oxygen.

[0012] Furthermore, the bottom of the frame is equipped with ground anchors that can be inserted into the ground. By inserting the ground anchors into the ground, the frame is anchored to the ground. The ground anchors can effectively disperse and resist external forces such as wind and equipment collision forces on the cultivation frame, preventing the frame from swaying or tilting and improving the stability of the cultivation frame.

[0013] Furthermore, the bottom of the frame is provided with a first screw hole, in which a screw rod that mates with the first screw hole is installed. The ground anchor is located at the bottom of the screw rod, and a crank handle is provided at the top of the screw rod. When fixing the cultivation frame, rotating the crank handle causes the screw rod to rotate. Since the screw rod mates with the first screw hole, the screw rod moves downward relative to the first screw hole until the ground anchor located at the bottom of the screw rod extends into the ground, thus fixing the frame.

[0014] Furthermore, the frame includes a base frame, side frames, and a top plate. The base frame is rectangular, and the side frames are inverted V-shaped. Two sets of side frames are provided, with their tops fixedly connected to the bottom surface of the top plate. The width of the top plate is less than or equal to the width of the top of the side frames. The two sets of base feet of the two sets of side frames are fixedly connected to two opposite sides of the base frame. The horizontal position of the cultivation trough is located between the top plate and the side of the base frame connected to the side frames. The rectangular base frame increases the support strength of the frame; the inverted V-shaped side frames, fixedly connected to the bottom surface of the top plate, improve the stability of the frame while reducing obstruction of the cultivation trough.

[0015] Furthermore, two supporting inclined plates are fixedly installed on the top plate, and several light lamps are installed at the bottom of the supporting inclined plates. When natural light is insufficient, the light lamps can be used to supplement the light and promote crop growth.

[0016] Compared with the prior art, the beneficial effects of this utility model are: This utility model discloses a multi-layer cultivation rack: 1. A lifting mechanism drives the support plates to rise or fall, thereby raising or lowering the cultivation troughs. This adjusts the distance between the cultivation troughs on each support plate, ensuring that the crops in each trough have sufficient growing space, guaranteeing good light and ventilation, and effectively improving the spatial adaptability of crops at different growth stages; 2. The cultivation troughs are installed on the sides of the support plates, and the area of ​​the support plates increases from top to bottom, ensuring that the cultivation troughs are not blocked by the support plates or other cultivation troughs, and ensuring that the crops receive more sunlight; 3. The rack is anchored to the ground by ground anchors, which can effectively disperse and resist external forces such as wind and equipment collisions, preventing the rack from swaying or tilting, and improving the stability of the cultivation rack; 4. When natural light is insufficient, artificial light can be used to supplement the light and promote crop growth. Attached Figure Description

[0021] Example 1 like Figures 1 to 5 The first embodiment of the multi-layer cultivation rack of this utility model is shown, which includes a frame 1, a support plate 3, a cultivation trough 4 and a lifting mechanism 2. The lifting mechanism 2 is installed on the frame 1, and multiple support plates 3 are connected to the lifting mechanism 2. The cultivation trough 4 is installed on the support plate 3.

[0022] This utility model discloses a multi-layer cultivation rack in which cultivation troughs 4 are installed on support plates 3, and crop seedlings are planted in the cultivation troughs 4. The frame body 1 provides support for the support plates 3 and the cultivation troughs 4. As the crops grow, the support plates 3 are raised or lowered by the lifting mechanism 2 according to the growth of the crops in the cultivation troughs 4 installed on each support plate 3. This causes the cultivation troughs 4 to rise or fall, adjusting the distance between the cultivation troughs 4 on each support plate 3. This ensures that the crops in each cultivation trough 4 have sufficient growing space, guaranteeing good light and ventilation, and effectively improving the spatial adaptability of crops at different growth stages.

[0023] like Figure 1 As shown, the lifting mechanism 2 includes multiple sets of telescopic rods 21, which are fixedly installed on the frame 1. The output ends of the multiple sets of telescopic rods 21 are respectively fixedly connected to multiple support plates 3, and the telescopic rods 21 extend or shorten in the vertical direction. When the lifting mechanism 2 is working, the telescopic rods 21 extend or shorten, and the output ends of the telescopic rods 21 rise or fall, thereby causing the support plates 3 fixedly connected to the output ends of the telescopic rods 21 to rise or fall, adjusting the growth space for the crops.

[0024] The cultivation trough 4 is fixedly installed on the side of the support plate 3, and the projected area of ​​the multiple support plates 3 increases sequentially from top to bottom in the horizontal direction. The cultivation trough 4 is installed on the side of the support plate 3, and the area of ​​the support plate 3 increases sequentially from top to bottom, ensuring that the cultivation trough 4 is not blocked by the support plate 3 or other cultivation troughs 4, thus ensuring that the crops receive sufficient sunlight. In this embodiment, an mounting plate 34 is fixedly installed on the side of the support plate 3, and the cultivation trough 4 is installed on the side of the mounting plate 34 away from the support plate 3, i.e., on the outer side of the mounting plate 34; the cultivation trough 4 is fixed to the mounting plate 34 with screws.

[0025] In this embodiment, as Figure 4 and Figure 5 As shown, there are three support plates 3, which are respectively labeled as the first support plate 31, the second support plate 32, and the third support plate 33. There are three sets of telescopic rods 21, which are respectively labeled as the first telescopic rod 22, the second telescopic rod 23, and the third telescopic rod 24. The first telescopic rod 22 is connected to the first support plate 31, the second telescopic rod 23 is connected to the second support plate 32, and the third telescopic rod 24 is connected to the third support plate 33. There are two of each of the first telescopic rods 22, the second telescopic rod 23, and the third telescopic rod 24. The first support plate 31 and the two first telescopic rods 22 are located between the two second telescopic rods 23, and the second support plate 32 and the two second telescopic rods 23 are located between the two third telescopic rods 24. The telescopic rods 21 are electric telescopic rods.

[0026] The working principle of the multi-layer cultivation rack in this embodiment is as follows: The cultivation trough 4 is installed on the mounting plate 34 on the side of the support plate 3. Crop seedlings are planted in the cultivation trough 4. The first telescopic rod 22 drives the first support plate 31 to rise and fall, the second telescopic rod 23 drives the second support plate 32 to rise and fall, and the third telescopic rod 24 drives the third support plate 33 to rise and fall, thereby causing the cultivation trough 4 installed on the three support plates 3 to rise or fall. The distance between the cultivation troughs 4 installed on adjacent support plates 3 is adjusted so that the growth space and growth conditions of the crops in different cultivation troughs 4 are adapted.

[0027] Example 2 This embodiment is the second embodiment of the multi-layer cultivation rack of this utility model. This embodiment is similar to the first embodiment, except that it also includes a water tank 5. The water tank 5 is set on the top surface of the support plate 3, and a water supply pipe 6 is connected to the water tank 5. The water supply pipe 6 is connected to the cultivation trough 4. Water or nutrient solution is injected into the water tank 5, and the water or nutrient solution is input into the cultivation trough 4 through the water supply pipe 6 to irrigate the crops.

[0028] like Figure 2 and Figure 4 As shown, the water supply pipeline 6 includes a main pipe 61 and multiple branch pipes 62. The main pipe 61 is connected to the water tank 5, and the multiple branch pipes 62 are connected to the main pipe 61. The outlets of the branch pipes 62 are located above the cultivation trough 4, and the multiple branch pipes 62 are evenly arranged along the length of the cultivation trough 4. The even arrangement of the multiple branch pipes 62 along the length of the cultivation trough 4 allows water or nutrient solution to flow evenly into different areas of the cultivation trough 4, ensuring that the crops receive uniform irrigation. In this embodiment, the outlets of the branch pipes 62 are equipped with spray heads 621, which can spray water or nutrient solution more evenly onto the crops. The mounting plate 34 is equipped with multiple placement slots 341, and the multiple branch pipes 62 pass through the multiple placement slots 341 respectively. In this embodiment, each water tank 5 is connected to two main pipes 61, and each main pipe 61 is connected to three branch pipes 62.

[0029] like Figure 1 As shown, the bottom of the cultivation trough 4 is provided with several drainage holes 41. The drainage holes 41 can drain the water in the cultivation trough 4 in a timely manner, preventing the crops from rotting due to excessive water accumulation. In this embodiment, each cultivation trough 4 is provided with 8 drainage holes 41 at its bottom.

[0030] The working principle of the multi-layer cultivation rack in this embodiment is as follows: After adjusting the distance between the lifting plates to a suitable range for crop growth by operating the telescopic rod 21, water is injected into the water tank 5. The water in the water tank 5 flows through the main pipe 61 and the branch pipe 62, and is sprayed onto the crops through the spray head 621 to irrigate the crops. The water that the crops fail to absorb in time flows out of the cultivation trough 4 through the drain hole 41.

[0031] Example 3 This embodiment is the third embodiment of the multi-layer cultivation rack of this utility model. This embodiment is similar to embodiment two, except that, as Figures 1 to 5 As shown, the bottom of the frame 1 is provided with a ground anchor 15 that can be inserted into the ground. The ground anchor 15 at the bottom of the frame 1 is inserted into the ground to anchor the frame 1 to the ground. The ground anchor 15 can effectively disperse and resist external forces such as wind force and equipment collision force on the cultivation frame, prevent the frame 1 from shaking or tilting, and improve the stability of the cultivation frame.

[0032] The bottom of the frame 1 is provided with a first screw hole, in which a screw rod 14 that mates with the first screw hole is installed. The ground anchor 15 is located at the bottom of the screw rod 14, and a crank handle 16 is located at the top of the screw rod 14. When fixing the cultivation frame, rotating the crank handle 16 causes the screw rod 14 to rotate. Since the screw rod 14 mates with the first screw hole, the screw rod 14 moves downward relative to the first screw hole until the ground anchor 15 at the bottom of the screw rod 14 extends into the ground, thus fixing the frame 1.

[0033] like Figure 1 and Figure 2 As shown, the frame 1 includes a base frame 11, side frames 12, and a top plate 13. The base frame 11 is a rectangular frame, and the side frames 12 are inverted V-shaped frames. There are two sets of side frames 12, and the tops of the two sets of side frames 12 are fixedly connected to the bottom surface of the top plate 13. The width of the top plate 13 is less than or equal to the width of the top of the side frames 12. The two sets of bottom feet of the two sets of side frames 12 are fixedly connected to the two opposite sides of the base frame 11. The horizontal position of the cultivation trough 4 is located between the top plate 13 and the side of the base frame 11 connected to the side frames 12. The rectangular base frame 11 can improve the support strength of the frame 1; the inverted V-shaped side frames 12, which are fixedly connected to the bottom surface of the top plate 13, can improve the stability of the frame 1 while reducing the obstruction of the cultivation trough 4 by the frame 1.

[0034] In this embodiment, as Figure 1 and Figure 2 As shown, the base frame 11 has a boss 111 on its side wall, and four bosses 111 are provided on the bosses 111, which are respectively located at the four corners of the base frame 11. The side frame 12 has a limiting member 121 on its outer side wall, and the limiting member 121 has a second screw hole that mates with the screw 14. The axis of the second screw hole coincides with the axis of the first screw hole. The limiting member 121 and the bosses 111 together restrict the position of the screw 14, preventing the screw 14 from shaking and further improving the stability of the frame 1. At the same time, the limiting member 121 can restrict the vertical movement of the crank handle 16, preventing the ground anchor 15 from going too deep into the ground.

[0035] like Figure 3 As shown, two supporting inclined plates 131 are fixedly installed on the top plate 13, and several light lamps 132 are installed at the bottom of the supporting inclined plates 131. When natural light is insufficient, the light lamps 132 can be used to supplement the light and promote crop growth.

[0036] The working principle of the multi-layer cultivation rack in this embodiment is as follows: During installation, the cultivation trough 4 is installed on the mounting plate 34, the frame 1 is placed on the ground, and the ground anchor 15 at the bottom of the screw 14 is passed through the second screw hole, so that the external thread of the screw 14 contacts the internal thread of the second screw hole. The crank handle 16 is rotated to drive the screw 14 to rotate, and the screw 14 moves downward relative to the second screw hole until the ground anchor 15 passes through the first screw hole. The crank handle 16 is rotated again, and the screw 14 moves downward relative to the first and second screw holes until the ground anchor 15 penetrates into the ground, anchoring the frame 1 to the ground, thus completing the installation of the multi-layer cultivation rack. Crops are planted in the cultivation trough 4, and the distance between the cultivation troughs 4 is adjusted to a suitable value according to the growth of the crops. The light intensity and illumination duration of the light lamp 132 are adjusted according to the light received by the crops to promote crop growth.

[0037] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0038] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
