[0009] The irrigation assembly is arranged above the top of the support frame, and each planting box is driven by the transmission chain to pass through the top of the support frame and then passes under the irrigation assembly.

[0010] In one embodiment, the driver includes a driving motor and a reducer, and the driving motor is drivingly connected to the driving wheel via the reducer.

[0011] In one of the embodiments, it further includes a chain limiting groove, which is arranged on the support frame, and a plurality of limiting rollers are arranged on the transmission chain, and each of the limiting rollers is rotatably arranged in the chain limiting groove.

[0012] In one embodiment, the number of the chain limiting grooves is two, the two chain limiting grooves are linear in shape, and the two chain limiting grooves are arranged on both sides of the center line connecting the driving wheel and the driven wheel.

[0013] In one embodiment, two of the limiting rollers form a group, and each of the chain joints is disposed between two of the limiting rollers in the same group.

[0014] In one of the embodiments, it also includes a balancing hanging basket, which includes a hanging basket body and a triangular balancing pendant, the two ends of the triangular balancing pendant are respectively connected to the two ends of the hanging basket body, the triangular balancing pendant is hung on the chain joint, the triangular balancing pendant is symmetrically arranged about the central axis of the chain joint in the vertical direction, the hanging basket body is symmetrically arranged about the central axis of the chain joint in the vertical direction, and the planting box is arranged on the hanging basket body.

[0015] In one embodiment, the rotary switch assembly includes an electromagnetic limiter.

[0016] In one of the embodiments, the rotary switch assembly further comprises a clamp, the movable end of the electromagnetic limiter is drivingly connected to the power input end of the clamp, and the clamp is used to clamp the transmission chain under the drive of the electromagnetic limiter.

[0017] In one embodiment, the irrigation assembly is configured to irrigate the first planting box passing through the top of the support frame, and the irrigation amount is 1 / 10-3 / 10 of the weight of the soil in each planting box.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figure 1 , Figure 2 and Figure 3 As shown, it is an irrigation gravity-driven hub-type three-dimensional planting rack device 10 according to an embodiment of the present invention, comprising a support frame 100, a driving assembly 200, a rotary switch assembly 300, an irrigation assembly 400 and a plurality of planting boxes 500;

[0034] The driving assembly 200 includes a driver 210, a driving wheel 220, a driven wheel 230 and a transmission chain 240. The driving wheel 220 and the driven wheel 230 are rotatably arranged at the bottom and the top of the support frame 100 respectively. The driver 210 is drivingly connected to the driving wheel 220. The transmission chain 240 is sleeved on the driving wheel 220 and the driven wheel 230 and meshed with the driving wheel 220 and the driven wheel 230. The transmission chain 240 is rotatably arranged with a plurality of chain joints 241. Each of the planting boxes 500 is movably connected to a chain joint 241.

[0035] The rotary switch assembly 300 is movably connected to the transmission chain 240, and the rotary switch assembly 300 is used to control the start or stop of the movement of the transmission chain 240;

[0036] The irrigation assembly 400 is disposed above the top of the support frame 100 , and each of the planting boxes 500 is driven by the transmission chain 240 to pass through the top of the support frame 100 and then passes under the irrigation assembly 400 .

[0037] In this embodiment, the transmission chain 240 is wound around the driving wheel 220 and the driven wheel 230. The driving wheel 220 drives the transmission chain 240 to move under the drive of the driver 210, and the transmission chain 240 drives the driven wheel 230 to rotate, so that the planting box 500 on the transmission wheel can move in sequence. It is worth mentioning that the driving wheel 220 and the driven wheel 230 are respectively arranged at the bottom and top of the support frame 100. The driving wheel 220 can be arranged at the top of the support frame 100 and the driven wheel 230 can be arranged at the bottom of the support frame 100, or the driving wheel 220 can be arranged at the bottom of the support frame 100 and the driven wheel 230 can be arranged at the top of the support frame 100. In this embodiment, the driving wheel 220 is arranged at the bottom of the support frame 100 and the driven wheel 230 is arranged at the top of the support frame 100. In this way, the transmission chain 240 can move along the vertical direction. In this way, the planting boxes 500 arranged along the transmission chain 240 can also be arranged along the vertical direction, thereby saving space in the horizontal direction, and more planting boxes 500 can be placed in a limited area, thereby improving the planting efficiency.

[0038] In this embodiment, the rotary switch assembly 300 is used to stop the transmission chain 240, or to prevent the transmission chain 240 from moving, so that the position of the transmission chain 240 is fixed, so that the height and position of the planting box 500 are also fixed. In one embodiment, when the rotary switch assembly 300 is turned on, the rotary switch assembly 300 stops the transmission chain 240 and prevents the transmission chain 240 from moving. When the rotary switch assembly 300 is turned off, the rotary switch assembly 300 loosens the transmission chain 240, and the transmission chain 240 can move. In one embodiment, when the rotary switch assembly 300 is turned off, the rotary switch assembly 300 stops the transmission chain 240 and prevents the transmission chain 240 from moving. When the rotary switch assembly 300 is turned on, the rotary switch assembly 300 loosens the transmission chain 240, and the transmission chain 240 can move. The implementation method of the rotary switch assembly 300 will be described in the subsequent embodiments. Through the rotary switch assembly 300, the planting box 500 can be controlled to be fixed at the corresponding position.

[0039] In this embodiment, in the initial state, the weight of each planting box 500 is equal or similar, therefore, the number of planting boxes 500 located on both sides (left and right sides in the figure) of the center line of the driving wheel 220 and the driven wheel 230 is equal, therefore, the total weight of the planting boxes 500 on both sides is equal, and the transmission chain 240 remains stationary. At this time, the driving wheel 220 is driven by the driver 210, and some of the planting boxes 500 are rotated in turn to pass through the top of the support frame 100 and rotate to the bottom of the irrigation assembly 400, and the irrigation assembly 400 irrigates the planting boxes 500.

[0040] In this way, the weight of the planting boxes 500 that are irrigated in sequence is greater than the weight of the planting boxes 500 that are not irrigated. When the total weight of the planting boxes 500 on the right is greater than the sum of the total weight of the planting boxes 500 on the left and the resistance of the transmission chain 240, the transmission chain 240 will be driven under the gravity of the planting boxes 500 on the right. At this time, the automatic transmission of the transmission chain 240 can be achieved without the drive of the driver 210, and the automatic movement of the planting boxes 500 can be achieved to the irrigation assembly 400. It is worth mentioning that in order to make the total weight of the planting boxes 500 on the right greater than the total weight of the left, the planting boxes 500 passing through the top need to be irrigated at intervals, otherwise each planting box 500 will be irrigated, and no weight difference will be formed, so that the transmission chain 240 cannot be automatically operated. Therefore, in this embodiment, the irrigation component 400 is configured to be turned on at intervals of a first preset time, and the rotary switch component 300 is configured to relax the transmission chain 240 at intervals of a second preset time. In this way, after the rotary switch component 300 loosens the transmission chain 240, the transmission chain 240 can operate under the weight difference, so that the planting box 500 located at the highest point on the left side moves to the bottom of the irrigation component 400, and then the irrigation component 400 is turned on to irrigate the planting box 500. Then, the rotary switch component 300 again blocks the movement of the transmission chain 240 and limits the movement of the transmission chain 240. Then, in the next cycle, the rotary switch component 300 again relaxes the transmission chain 240, and the irrigation component 400 irrigates the next layer of planting boxes 500, and the cycle continues. It is worth mentioning that the water irrigated in the planting box 500 will gradually evaporate with the passage of time. Thus, as the distance from the irrigation assembly 400 increases, the moisture in the planting box 500 gradually decreases. Thus, the water content in the planting box 500 on the right side that has passed through the irrigation assembly 400 is greater than the water content in the planting box 500 on the left side that has evaporated for a long time, thereby forming a weight difference between the planting box 500 on the left and the planting box 500 on the right. Therefore, by maintaining the time interval for opening the irrigation assembly 400 and the time interval for opening and closing the rotary switch assembly 300, the automatic operation of the transmission chain 240 can be realized, thereby automatically transferring the planting boxes 500 to the bottom of the irrigation assembly 400 for irrigation in turn, effectively reducing the volume of the irrigation assembly 400 and effectively saving energy consumption.

[0041] It is worth mentioning that in this embodiment, the different planting boxes 500 on the transmission chain 240 can be divided into layers, and there are multiple planting boxes 500 on each layer. Figure 2 and Figure 4 ,in, Figure 1 In the figure, from the side, there are 20 layers of planting boxes 500 distributed along the transmission chain 240, including 10 layers on the left and 10 layers on the right. Figure 4From the perspective of , each layer of planting boxes 500 includes 6 planting boxes 500 or 4 planting boxes 500.

[0042] In one embodiment, if Figure 4 As shown, the irrigation assembly 400 includes a plurality of irrigators 410, each of which is arranged at equal distances. In this embodiment, each of the irrigators 410 is aligned one by one with a plurality of planting boxes 500 on the same layer.

[0043] In order to provide buffering and damping for the movement of the transmission chain 240 and the planting box 500, in one embodiment, the driver 210 includes a driving motor and a reducer (not shown), and the driving motor is connected to the driving wheel 220 through the reducer.

[0044] In this embodiment, the input end of the reducer is connected to the power output end of the drive motor, and the output end of the reducer is connected to the driving wheel 220. By setting a reducer connected to the driving wheel 220, the reducer can provide damping for the rotation of the driving wheel 220. In this way, when the drive motor is not working and the rotation switch assembly 300 releases the transmission chain 240, the transmission chain 240 moves under the action of the weight difference between the planting boxes 500 on the left and right sides, and the transmission chain 240 drives the driving wheel 220 to move, while the reducer on the driving wheel 220 provides damping for the rotation of the driving wheel 220, and provides buffering and damping for the transmission chain 240 to prevent the planting box 500 from falling in a free fall, thereby making the movement of the planting box 500 more stable and preventing the planting box 500 from swinging significantly.

[0045] In order to make the movement of the planting box 500 more stable, keep the planting box 500 balanced, and further avoid the swing and shaking of the planting box 500, in one embodiment, please combine Figure 2 , Figure 4 and Figure 5 The planting rack device 10 also includes a chain limiting groove 110, which is arranged on the support frame 100, and a plurality of limiting rollers 242 are arranged on the transmission chain 240, and each of the limiting rollers 242 is rollingly arranged in the chain limiting groove 110.

[0046] In this embodiment, please combine Figure 2 , Figure 4 and Figure 5The chain limit groove 110 is in a U-shape, so the chain limit groove 110 is also called a U-shaped chain limit groove. A plurality of limit rollers 242 are equidistantly arranged on the transmission chain 240, and each limit roller 242 is rotatably arranged on the transmission chain 240. After the limit roller 242 enters the chain limit groove 110, the circumferential surface of the limit roller 242 can abut against the side wall of the chain limit groove 110. In this way, the side walls on both sides of the chain limit groove 110 abut against the limit roller 242, so that the transmission chain 240 can be prevented from shaking and swaying, so that the transmission chain 240 moves more smoothly, so that the planting box 500 driven by the transmission chain 240 can move more smoothly and maintain balance.

[0047] In one embodiment, Figure 4 As shown, there are two chain limiting grooves 110 , and the two chain limiting grooves 110 are linear in shape. The two chain limiting grooves 110 are arranged on both sides of the center line connecting the driving wheel 220 and the driven wheel 230 .

[0048] In this embodiment, Figure 4 As shown, one chain limit groove 110 is arranged on the left side of the center line connecting the driving wheel 220 and the driven wheel 230, and the other chain limit groove 110 is arranged on the right side of the center line connecting the driving wheel 220 and the driven wheel 230. In this way, when the transmission chain 240 moves upward or downward in the vertical direction, the chain limit groove 110 can play a good limiting role on the limit roller 242, thereby avoiding the shaking and swaying of the transmission chain 240. Specifically, as the limiting roller 242 moves downward from the top of the support frame 100, it enters the top of the right chain limiting groove 110, and then moves to the bottom near the support frame 100, and then comes out from the bottom end of the right chain limiting groove 110, and then moves along the circumferential direction of the driving wheel 220 to the bottom end of the left chain limiting groove 110, enters the left chain limiting groove 110 from the bottom end of the left chain limiting groove 110, and moves upward along the left chain limiting groove 110 until it moves to the top of the left chain limiting groove 110, comes out from the top of the left chain limiting groove 110, moves along the circumferential direction of the driven wheel 230 to the top of the right chain limiting groove 110, and enters the right chain limiting groove 110 again.

[0049] In order to maintain the balance of each planting box 500, so that the bottom of the planting box 500 remains parallel to the horizontal direction, in one embodiment, please combine Figures 2 to 5The planting rack device 10 also includes a balanced hanging basket 510, which includes a hanging basket body and a triangular balanced hanger 520, the two ends of the triangular balanced hanger 520 are respectively connected to the two ends of the hanging basket body, the triangular balanced hanger 520 is hung on the chain joint 241, the triangular balanced hanger 520 is symmetrically arranged about the central axis of the chain joint 241 in the vertical direction, the hanging basket body is symmetrically arranged about the central axis of the chain joint 241 in the vertical direction, and the planting box 500 is arranged on the hanging basket body.

[0050] In this embodiment, the balancing hanging basket 510 is hung on the chain joint 241 through the triangular balancing hanging piece 520. Since both ends of the balancing hanging basket 510 and both ends of the triangular balancing hanging piece 520 are symmetrical about the central axis of the chain joint 241 in the vertical direction, the gravity at both ends is equal. In this way, the balancing hanging basket 510 can remain horizontal. Even if the balancing hanging basket 510 moves to the top and bottom of the balancing frame along the transmission chain 240 and moves in a circle around the driven wheel 230 or the driving wheel 220, it can still maintain balance under the action of gravity, thereby making the bottom of the planting box 500 located on the balancing hanging basket 510 also maintain horizontality. In this embodiment, a balancing hanging basket 510 is provided on each layer, and 4 planting boxes 500 are provided on each balancing hanging basket 510.

[0051] In order to keep the balancing hanging basket 510 and the planting box 500 balanced, in one embodiment, two of the limiting rollers 242 form a group, and each of the chain joints 241 is disposed between the two limiting rollers 242 in the same group.

[0052] In this embodiment, two limiting rollers 242 support and limit a chain joint 241, so that the chain joint 241 can be prevented from shaking, thereby allowing the balancing hanging basket 510 to maintain balance, and allowing the planting box 500 to maintain balance.

[0053] In one embodiment, the rotary switch assembly 300 includes an electromagnetic stopper. In this embodiment, the electromagnetic stopper is used to control or drive the start or stop of the movement of the transmission chain 240. For example, after the electromagnetic stopper is powered on, the electromagnetic stopper loosens the transmission chain 240, and the transmission chain 240 can move. After the electromagnetic stopper is powered off, the electromagnetic stopper prevents the transmission chain 240 from moving under the action of elastic force. For another example, after the electromagnetic stopper is powered on, the electromagnetic stopper prevents the transmission chain 240 from moving. After the electromagnetic stopper is powered off, the electromagnetic stopper loosens the transmission chain 240, and the transmission chain 240 can move.

[0054] In one embodiment, the rotary switch assembly 300 further includes a clamp, the movable end of the electromagnetic limiter is drivingly connected to the power input end of the clamp, and the clamp is used to clamp the transmission chain 240 under the drive of the electromagnetic limiter.

[0055] In this embodiment, when the clamp clamps the transmission chain 240, the transmission chain 240 stops moving, and when the clamp releases the transmission chain 240, the transmission chain 240 can move. Specifically, the movable end of the electromagnetic limiter is drivingly connected to the power input end of the clamp, so that when the electromagnetic limiter is actuated, it can drive the power input end of the clamp to rotate, thereby clamping or loosening the power output end of the clamp. For example, when the electromagnetic limiter is powered on, the movable end of the electromagnetic limiter drives the power input end of the clamp to actuate, so that the power output end of the clamp is clamped, so that the transmission chain 240 stops moving, and then the position of the planting box 500 can be fixed. In this way, through the cooperation of the electromagnetic limiter and the clamp, the movement of the transmission chain 240 can be controlled according to the irrigation amount, sunlight, and temperature, thereby controlling the movement and fixed position of the planting rack.

[0056] In one embodiment, the irrigation assembly 400 is configured to irrigate the first planting box 500 passing through the top of the support frame 100, and the irrigation amount is 1 / 10-3 / 10 of the weight of the soil in each planting box 500. The number of the planting boxes 500 distributed along the transmission chain 240 is 12-24 groups on both sides.

[0057] In this embodiment, each layer of planting boxes 500 is a group of planting boxes 500, and the planting boxes 500 of each layer on the support frame 100 are distributed along the transmission chain 240. Therefore, there are 10 layers of planting boxes 500 on the left side of the center line of the driving wheel 220 and the driven wheel 230, and there are 10 layers of planting boxes 500 on the right side of the center line of the driving wheel 220 and the driven wheel 230. And with the movement of the transmission chain 240, the distribution of 10 layers on the left and right is always maintained. In this way, since the weight of the amount of water irrigated in the planting box 500 each time is 1 / 10-3 / 10 of the weight of the soil in the corresponding planting box 500, since the planting box 500 on the right is 1 / 10-3 / 10 of the weight of the soil in the corresponding planting box 500, the planting box 500 on the right is 1 / 10-3 / 10 of the weight of the soil in the corresponding planting box 500. The irrigation time is shorter than the time from the last irrigation of the planting box 500 on the left side. Therefore, the evaporation of water in the planting box 500 on the right side is less, and the amount of water retained is more. In this way, the weight of the 10-layer planting box 500 on the right side that has just been irrigated is about 2 to 4 times the weight of the 10-layer planting box 500 on the left side. In this way, when the total weight of the planting box 500 on the right side is greater than the total weight of the planting box 500 on the left side and the resistance to the movement of the transmission chain 240, the transmission chain 240 moves. The weight difference allows the transmission chain 240 to move when the driver 210 is not working, thereby realizing automatic driving of the planting box 500 and effectively reducing energy consumption. It is worth mentioning that the resistance refers to the resistance of the planting rack device 10 itself, which can be friction or damping including a reducer. When the weight difference is greater than the resistance, the transmission chain 240 can achieve automatic movement.

[0058] In one embodiment, the irrigation amount is 2 / 10 of the weight of the soil in each planting box 500. Thus, after the planting boxes 500 on the right are irrigated and the planting boxes 500 on the left and right sides evaporate for different lengths of time, the weight of the planting box 500 on the right is greater than the weight of the planting box 500 on the left. Thus, the difference between the weight of the planting box 500 on the right and the weight of the planting box 500 on the left is greater than the resistance of the movement of the transmission chain 240, so that the transmission chain 240 can run automatically.

[0059] In one embodiment, the driver is configured to drive the transmission chain to move at a speed of 0.5-2 revolutions / hour before the planting box is irrigated;

[0060] The irrigation assembly is configured to calculate an irrigation amount according to soil weight, light intensity, ambient temperature, ambient humidity and crop variety in the planting box when a planting box moves below the irrigation assembly, and irrigate the planting box based on the calculated irrigation amount;

[0061] The rotary switch assembly is configured to stop the movement of the transmission chain when a planting box moves below the irrigation assembly;

[0062] The driver is configured to stop working when a preset number of planting boxes have completed irrigation;

[0063] The rotary switch assembly is configured to loosen the transmission chain at a second preset time interval so that the transmission chain moves under the action of the weight difference, and stop the movement of the transmission chain after a third preset time of loosening the transmission chain so that the transmission chain maintains a speed of 0.5-2 turns / hour.

[0064] In this embodiment, the transmission chain is kept moving at a speed of 0.5-2 turns / hour, so that each planting box can be irrigated evenly, and when the water evaporates to be relatively dry, it can be irrigated and replenished with water in time. Figure 1 When the planting box moves to point C, the planting box is located below the irrigation component, the rotary switch component starts, the transmission chain stops moving, and the irrigation component irrigates the planting box. AI (artificial intelligence) calculates the irrigation amount based on soil weight, light intensity, ambient temperature, ambient humidity and crop variety. For example, light intensity and ambient temperature are proportional to the irrigation amount, and ambient humidity is inversely proportional to the irrigation amount. Each crop variety corresponds to a correction coefficient, and the irrigation amount is calculated based on 2 / 10 of the soil weight. In this way, the irrigation amount can be accurately calculated so that when the irrigated planting box passes the bottom of the planting rack and returns to the top again, at point D, the evaporation of water in the planting box reaches the maximum, and the humidity of the planting soil is at the critical point required by the plant, that is, the soil is relatively dry. In this way, it can return to point C as soon as possible and replenish water in time.

[0065] In addition, in this embodiment, when a preset number of planting boxes completes irrigation, the driver stops working. The preset number is calculated based on the irrigation amount. Under normal circumstances, the preset number is half of the total number. In this way, after the irrigation on the left side is completed, the weight difference between the planting rack on the left and the planting rack on the right can be greater than the resistance, so that the transmission chain can run automatically.

[0066] In addition, in one embodiment, the driver is further configured to drive the transmission chain to move at a speed of 0.5-2 revolutions / hour during the day when there is no sunlight. In this embodiment, when there is no sunlight during the day, the evaporation of the planting rack is small and the weight difference that can drive the transmission chain to move cannot be formed. At this time, the driver drives the transmission chain to move to ensure that each planting rack can be irrigated in time.

[0067] It should be understood that in the above embodiments, the control of the driver, the irrigation assembly and the rotary switch assembly may be independently controlled or implemented under the control of a control module.

[0068] In one embodiment, the irrigation gravity-driven hub-type three-dimensional planting rack device further includes a control module, which is electrically connected to the driver, the irrigation component and the rotary switch component respectively;

[0069] The control module is configured to: before the planting box is irrigated, control the driver to drive the transmission chain to move at a speed of 0.5-2 revolutions / hour;

[0070] When a planting box moves under the irrigation component, the irrigation amount is calculated according to the soil weight, light intensity, ambient temperature, ambient humidity and crop variety in the planting box, and the irrigation component is controlled to irrigate the planting box based on the calculated irrigation amount;

[0071] When a planting box moves to below the irrigation assembly, the rotary switch assembly is controlled to stop the movement of the transmission chain;

[0072] When the preset number of planting boxes have completed irrigation, the control drive stops working;

[0073] The rotary switch assembly is controlled to loosen the transmission chain at a second preset time interval so that the transmission chain moves under the action of the weight difference, and the movement of the transmission chain is stopped after a third preset time of loosening the transmission chain so that the transmission chain maintains a speed of 0.5-2 turns / hour.

[0074] In one embodiment, the control module is configured to control the driver to drive the transmission chain to move at a speed of 0.-25 revolutions / hour during daytime when there is no sunlight.

[0075] In this embodiment and the following embodiments, 1 circle refers to Figure 1 Starting from a certain point in the middle, it bypasses the driving wheel and the driven wheel and returns to the starting point.

[0076] Embodiment 2

[0077] In this embodiment:

[0078] 1. The planting rack rotates 1 circle / 2 hours on average (the time will be shortened at noon depending on the light intensity and evaporation), and the operating time is about 12 hours per day;

[0079] 2. When the planting box is at point C, the electromagnetic limiter starts the planting rack to stop running, and the irrigation device starts irrigation;

[0080] 3. The irrigation amount of the irrigator depends on the light intensity, ambient temperature, ambient humidity and crop variety. The AI ​​intelligent management system calculates and determines the irrigation amount so that when the planting box runs to point D, the humidity of the planting soil is at the critical point required by the plants, that is, the soil is relatively dry;

[0081] 4. Planting boxes A and B have 6-12 layers respectively. As time goes by, the water in the planting boxes at A and the lower end of B will gradually evaporate under photosynthesis. When it reaches C at the end of A, the water evaporation of the planting box reaches the critical point required by the plants, and the weight of the planting box is the lowest.

[0082] 5. The irrigation volume of the irrigation device is about 1 / 10-3 / 10 of the weight of the soil in the planting box (depending on the humidity suitable for plant growth). The minimum value is 2 / 10, which means that the planting box at the B end will be about 10 layers heavier than the planting box at the A end (calculated as 10 layers) * 2 / 10 = 2 times the weight. Since the weight of the soil from C to D is gradually reduced according to the evaporation of plant photosynthesis, the weight increase at the B end is less than 2 times that at the A end, and 1 times is taken as an approximate value for calculation;

[0083] 6. Assume that the number of planting boxes per layer is Z (6 boxes), the number of planting racks is L (10 layers), the weight of the soil in the planting boxes is Y (10 kg), and the increased weight ratio is X

[0084] The weight of end B is about Z*L*Y*X, 6*10*10=600+600=1200kg

[0085] The weight of end A is 6*10*10=600kg

[0086] Designed planting rack running resistance <600kg

[0087] When the weight at the B end is greater than the weight at the A end + the running resistance of the planting rack, the planting rack can rotate;

[0088] 7. The motor is started only when there is no light to evaporate the plants, or when the planting rack needs to be rotated for harvesting and maintenance. When the motor is not working, its reducer is used as system damping.

[0089] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0090] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
