DETAILED DESCRIPTION

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

[0027] Soil cultivation circular containers often use a top-down irrigation method, generally through multiple fixed water outlet pipes for uniform irrigation. However, in order to achieve uniform irrigation, one cultivation container in this mode needs to be connected to multiple water outlet pipes, which is a large workload, and once fixed, it cannot be moved. In addition, it is difficult to accurately guarantee the water output of each water outlet pipe. The French Institute of Agricultural Sciences uses a modular irrigation method to automatically irrigate each cultivation container in combination with a diverter. The plants in this circular container are cultivated and grown around the circular container, and the diverter is located in the center of the circular container. However, this method requires the cultivation to be easily moved to the position of the irrigation device, which also causes a lot of handling workload. In addition, the water injection head of this mode is inserted into the diverter from top to bottom, which is easy to cause damage to the leaves of large plants.

[0028] Therefore, in order to solve the problems existing in the above status quo, the present invention provides a plant root irrigation system based on a double-cylinder cultivation container, such as Figure 1 and Figure 2, including a mobile frame 11 placed above the cultivation frame 1, and the mobile frame 11 is provided with an irrigation component that moves around the center of the root cultivation container 2 and is used to irrigate the plants in the root cultivation container 2. The cultivation frame 1 and the root cultivation container 2 can be a cultivation frame 1 and a transparent root cultivation container 2 of a plant root automatic imaging system based on a double-cylinder cultivation container with a publication number of CN110089307A, which will not be described here. For our round container root cultivation container 2, the plant 3 grows in the center of the root cultivation container 2, so it is necessary to irrigate the plant 3 by surrounding the root cultivation container 2.

[0029] like Figure 1 and Figure 2 When it is necessary to irrigate the plants in the root cultivation container 2 in the cultivation frame 1, the mobile frame 11 is placed above the cultivation frame 1, so that the irrigation component on the mobile frame 11 moves around the center of the root cultivation container 2 and irrigates the plants in the root cultivation container 2. At this time, since the irrigation component can be moved, the number of water outlets in the irrigation component can be reduced, so that the transparent root cultivation container 2 in the cultivation frame 1 can be automatically irrigated, and the plants in the root cultivation container 2 can be evenly irrigated, which reduces the operator's workload, improves irrigation efficiency, and saves time and cost. When the irrigation component is not needed, the mobile frame 11 can be moved down from the cultivation frame 1, which is easy to operate and convenient for moving the cultivation frame 1.

[0030] like Figure 1 and Figure 2 The irrigation assembly includes a fixed plate 12 arranged on the mobile frame 11 and located above the root cultivation container 2. The fixed plate 12 is provided with a nozzle 13 facing the inlet of the root cultivation container 2. The nozzle 13 includes a vertical tube penetrating the fixed plate 12 in the vertical direction. Both ends of the vertical tube extend out of the upper and lower ends of the fixed plate 12. The lower end of the vertical tube faces the cylinder of the root cultivation container 2 and is expanded. The lower end of the vertical tube closes the upper end opening. The upper end of the mobile frame 11 is provided with a water storage box 14. The water storage box 14 is provided with a connecting pipe 141 connecting the water storage box 14 and the nozzle 13. The connecting pipe 141 is connected to the upper end opening of the vertical pipe. The lower end of the vertical pipe is closed and has a plurality of watering holes. The connecting pipe 141 is provided with a water pump 142 for pumping water in the water storage box 14 into the nozzle 13. The water pump 142 is fixed to the upper end of the mobile frame 11. The water pump 142 adopts a peristaltic pump to ensure the irrigation accuracy.

[0031] like Figure 1 and Figure 2The water pump 142 pumps the water in the water storage box 14 into the nozzle 13 through the connecting pipe 141, and then the water enters the root cultivation container 2 for irrigation. The bottom height of the water storage box 14 at the water inlet of the connecting pipe 141 is lower than the bottom height of the water storage box 14 on the side of the water storage box 14 opposite to the water inlet of the connecting pipe 141. The opening of the water storage box 14 faces upward, which is convenient for the user to add water to the water storage box 14.

[0032] like Figure 1 and Figure 2 The fixed plate 12 is an arc-shaped plate distributed along the cylindrical arc of the root cultivation container 2, and a first driving member for driving the nozzle 13 to move along the arc-shaped plate is provided on the fixed plate 12.

[0033] like Figure 2 and Figure 4 The first driving member includes an arc-shaped rack 15 distributed along the arc-shaped plate, a slide plate 151 placed above the arc-shaped rack 15, and a gear 152 rotatably arranged on the slide plate 151 and meshing with the arc-shaped rack 15. A first motor 153 is provided at the upper end of the slide plate 151 to drive the gear 152 to rotate. The teeth of the arc-shaped rack 15 are distributed on the outer circular wall of the arc-shaped rack 15. The slide plate 151 extends out of the fixed plate 12 and extends toward the center direction of the root cultivation container 2. The nozzle 13 is fixed on one side of the slide plate 151 extending out of the fixed plate 12. When the first motor 153 drives the gear 152 to rotate so that the gear 152 moves along the arc-shaped rack 15, a rolling body 154 is provided on the slide plate 151 to make the slide plate 151 move with the gear 152. Arc-shaped plates are extended from both ends of the skateboard 151, and the fixing parts include a first roller 1511 and a second roller 1512 which are rotatably arranged at both ends of the arc-shaped plates extending from the skateboard 151 respectively, and the first roller 1511 and the second roller 1512 are both rotatably connected to the skateboard 151, and the first roller 1511 is distributed close to the gear 152, and the first roller 1511 includes a vertical cylinder 1513 arranged on the skateboard 151, and the lower end of the cylinder 1513 is rotatably connected to a first rotating wheel 1514 that rolls along the outer wall of the arc-shaped plate, and the side of the cylinder 1513 toward the arc-shaped plate is rotatably connected to a second rotating wheel 1515 that rolls along the upper end surface of the arc-shaped plate, and the second roller 1512 rolls along the side of the arc-shaped rack 15 away from the gear 152. When the first motor 153 drives the size to rotate, the gear 152 moves along the arc-shaped rack 15. At this time, the first roller 1511 and the second roller 1512 make the slide plate 151 move together with the gear 152, thereby facilitating the nozzle 13 on the slide plate 151 to move around the center of the root cultivation container 2 and evenly irrigate the plants in the root cultivation container 2. At this time, the number of nozzles 13 and the number of connecting pipes 141 required to irrigate the plants in a root cultivation container 2 are reduced.

[0034] like Figure 2 and Figure 4The number of the fixed plates 12 is set to be two plates distributed on opposite sides of the root cultivation container 2. The two arc-shaped plates form the outer arc of the cylinder of the root cultivation container 2. At this time, both ends of the arc-shaped rack 15 located on each fixed plate 12 extend out of both ends of the fixed plate 12, so that the nozzle 13 on the slide plate 151 can irrigate the plants at the junction of the two fixed plates 12.

[0035] like Figure 2 and Figure 3 The movable frame 11 is provided with a second driving member for moving the fixed plate 12 away from the root cultivation container 2 .

[0036] like Figure 2 and Figure 3 The second driving member includes a hinged rod 16 hinged on the fixed plate 12, and one end of the hinged rod 16 away from the fixed plate 12 is hinged on the mobile frame 11. The mobile frame 11 is hinged with a telescopic rod 161 at the lower end of the fixed plate 12. The mobile frame 11 is provided with a third driving member for driving the telescopic rod 161 to move up and down;

[0037] like Figure 2 and Figure 3 The third driving member includes a horizontal plate 171 mounted on the mobile frame 11 through the vertical plate 17, and a screw rod 172 is rotatably connected to the horizontal plate 171. The end of the telescopic rod 161 away from the fixed plate 12 is sleeved outside the screw rod 172 and threadedly connected to the screw rod 172. The screw rod 172 is driven by a second motor 173 fixed at the lower end of the horizontal plate 171.

[0038] like Figure 2 and Figure 3 When the second motor 173 drives the screw rod 172 to rotate, one end of the telescopic rod 161 on the screw rod 172 moves up and down along the screw rod 172. When the screw rod 172 drives one end of the telescopic rod 161 to move downward, the other end of the telescopic rod 161 also moves downward, thereby causing the hinged rod 16 to swing downward, causing the fixed plate 12 to move toward the root cultivation container 2, until the opposite ends of the arc-shaped racks 15 on the fixed plates 12 on opposite sides of the root cultivation container 2 collide with each other, so that the nozzle 13 on the slide plate 151 is located above the inlet of the root cultivation container 2. At this time, the first motor 153 drives the slide plate 151 to move, thereby facilitating the nozzle 13 to irrigate; when the screw rod 172 drives one end of the telescopic rod 161 to move upward, the telescopic rod 161 extends to its maximum length. Subsequently, as the telescopic rod 161 continues to move upward, the end of the telescopic rod 161 away from the screw rod 172 drives the fixed plate 12 to move away from the root cultivation container 2, and the hinged rod 16 swings upward.

[0039] like Figure 2 and Figure 3The mobile frame 11 includes criss-cross connecting plates 111 distributed along the periphery of each root cultivation container 2. The openings formed between the connecting plates 111 correspond to each root cultivation container 2. A plurality of vertical rods 112 are arranged above the connecting plates 111. The height of the vertical rods 112 is higher than the height of the plants. One end of each vertical rod 112 away from the connecting plates 111 is connected by a connecting rod 113; the water storage box 14 is arranged on the connecting rod 113.

[0040] like Figure 2 and Figure 5 , the second driving member is arranged on the moving plate 114, the moving plate 114 is slidably connected to the connecting plate 111, and the connecting plate 111 is provided with a fourth driving member for driving the moving plate 114 to move along the length direction of the connecting plate 111. The moving frame 11 is provided with a fixing member for fixing each connecting pipe 141, and the fixing member includes a guide plate 18 arranged on the moving frame 11 and distributed along the height direction of the moving frame 11, and the guide plate 18 is arranged corresponding to the number of connecting pipes 141, and each guide plate 18 is provided with a plurality of positioning rings 181 for fixing the corresponding connecting pipe 141 on the guide plate 18, and each positioning ring 181 is distributed along the vertical direction, and the connecting pipe 141 at the water outlet of the water pump 142 passes through each positioning ring 181 and is connected with the nozzle 13.

[0041] like Figure 1 and Figure 5 The fourth driving member includes a chain 182 arranged on one side of the guide plate 18 and distributed along the length direction of the guide plate 18. At this time, the guide plate 18 is an L-shaped plate, one side of which is fixed to the connecting rod 113 at the upper end, and the other end is fixed to the vertical vertical rod 112. At this time, a guide groove 183 is provided on the guide plate 18 for the chain 182 to be distributed along the length of the guide plate 18 in the guide plate 18. A driving shaft 184 is rotatably connected to the vertical rod 112, and the driving shaft 184 is provided with active teeth 185 engaged with each chain 182. The driving shaft 184 is driven to rotate by a third motor 186 fixed to the vertical rod 112. One end of the chain 182 extends out of the guide plate 18 and is connected to the moving plate 114. At this time, the third motor 186 drives the driving shaft 184 to rotate, which can drive each chain 182 to move, so that the chain 182 drives the moving plate 114 to move along the length direction of the horizontal connecting plate 111.

[0042] like Figure 1 and Figure 5The two opposite sides of the root cultivation container 2 use a single-bend chain 182 to pull the moving plate 114, and the two semi-rings of the adjacent root cultivation containers 2 are positioned and automatically surrounded by irrigation, and irrigation is performed once for each distance of the root cultivation container 2. The height of the second driving member on the moving plate 114 is lower than the height of the plant 3, and the irrigation component adopts a semi-circular umbrella-shaped telescopic mode, which is in a contracted state during the movement, that is, the fixed plate 12 is located away from the root cultivation container 2, at this time, the irrigation component and the fourth driving member are reduced. The irrigation component is in an expanded state when the moving plate 114 is in a stationary state, that is, the fixed plate 12 is located close to the root cultivation container 2, and the plant 3 is surrounded by irrigation.

[0043] like Figure 1 A plant root irrigation system based on a double-cylinder cultivation container also includes a lifting device 19 for placing the mobile frame 11 above the cultivation frame 1, and the lifting device 19 is lifted by a crane.
