Description

Technical Field

[0001] This utility model belongs to the field of chili seedling cultivation technology, specifically a water and fertilizer integrated seedling tray for chili seedling cultivation. Background Technology

[0002] Seedling tray raising is a method for rapidly cultivating high-quality seedlings. With its advantages of water and fertilizer conservation, ease of management, and high transplant survival rate, it has become the mainstream method for intensive chili seedling cultivation. The holes in seedling trays are mainly square or round; in actual cultivation, 128-hole square trays are commonly used for cultivating chili seedlings. During chili seedling cultivation, water and fertilizer supply is crucial for the normal growth of seedlings. With the gradual improvement of integrated water and fertilizer systems in agriculture, water and fertilizer solutions are first prepared in the water and fertilizer tank of the integrated system and then sprayed into the seedling trays through methods such as spraying or manual irrigation. However, this method suffers from uneven water and fertilizer supply, seriously affecting the seedling cultivation effect. Therefore, it is necessary to design a chili seedling tray that can uniformly supply water and fertilizer to chili seedlings using an integrated water and fertilizer system. Utility Model Content

[0003] The purpose of this invention is to provide a water and fertilizer integrated seedling tray for chili seedling cultivation that can uniformly supply water and fertilizer to chili seedlings, in order to solve the technical problem that uneven water and fertilizer supply in each seedling hole during chili seedling cultivation leads to uneven growth of chili seedlings and affects the seedling cultivation effect.

[0004] To solve the above technical problems, the technical solution of this utility model is as follows: a water and fertilizer integrated seedling tray for chili seedling cultivation, including a water and fertilizer trough and a placement frame for placing the seedling tray. The water and fertilizer trough is located below the placement frame and is connected to the output end of the water and fertilizer integrated machine through a pipe. Hydraulic telescopic cylinders are provided on both sides of the placement frame. A support frame is fixedly connected to the bottom of the water and fertilizer trough. Four support rods are provided around the placement frame. Each support rod has a sliding groove on its side wall. A slider is slidably connected to the sliding groove. The slider is fixedly connected to the outer side of the four corners of the placement frame. The lower ends of both sides of the placement frame are fixedly connected to the output ends of the hydraulic telescopic cylinders. Both hydraulic telescopic cylinders are connected to a hydraulic power unit.

[0005] Furthermore, the hydraulic power unit includes a motor-driven hydraulic oil pump, a hydraulic oil tank, and a hydraulic synchronous flow divider valve. The hydraulic synchronous flow divider valve is fixedly connected to the output end of the hydraulic oil pump, and the hydraulic synchronous flow divider valve is connected to the two hydraulic telescopic cylinders respectively.

[0006] Furthermore, the water-fertilizer tank has an inlet at one end, and an inlet pipe is fixedly connected to the inlet. The bottom of the water-fertilizer tank has a drain outlet, and a recovery pipe is fixedly connected to the drain outlet.

[0007] Furthermore, a support base plate is fixedly connected to the bottom of the support rod, and the bottom of each hydraulic telescopic cylinder is fixedly connected to the upper end of the support base plate.

[0008] Furthermore, when the placement frame is lifted to a high position by the hydraulic telescopic cylinder, a pressure relief support column is placed between the support base plate and the placement frame.

[0009] This utility model has the following advantages compared with the prior art:

[0010] This invention utilizes a water-fertilizer trough and a height-adjustable placement frame driven by a hydraulic telescopic cylinder. Seedling trays are placed on the placement frame, and the height of the frame is adjusted by controlling the hydraulic telescopic cylinder, immersing the top of the seedling trays in the water-fertilizer trough for irrigation. This replaces the traditional sprinkler irrigation method, improving irrigation efficiency and ensuring even distribution of water and fertilizer, resulting in relatively uniform growth of the chili seedlings. After irrigation, the height of the placement frame is adjusted to prevent the bottom of the trays from being submerged in the fertilizer solution for an extended period, thus preventing root rot due to insufficient ventilation.

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] like Figures 1 to 4The illustration shows a water and fertilizer integrated seedling tray for chili seedling cultivation, comprising a water and fertilizer tank 1 and a placement frame 2 for placing the seedling trays. The water and fertilizer tank 1 is a square, open-topped water tank. The placement frame 2 is a welded steel frame with internal steel frame dimensions matching the size of the seedling trays. The water and fertilizer tank 1 is located directly below the placement frame 2 and is connected to the output end of the water and fertilizer integrated machine via a pipe. Hydraulic telescopic cylinders 3 are installed on both sides of the placement frame 2; the two hydraulic telescopic cylinders 3 are of the same model. A support frame 4 is fixedly connected to the bottom of the water and fertilizer tank 1 to support and fix the water and fertilizer tank. 1. The placement rack 2 is provided with four support rods 5 around its perimeter. Each support rod 5 has a sliding groove 6 on its side wall. The sliding groove 6 is slidably connected to a slider 7. The slider 7 is fixedly connected to the outer side of the four corners of the placement rack 2. The lower ends of both sides of the placement rack 2 are fixedly connected to the output ends of the hydraulic telescopic cylinders 3. When the hydraulic telescopic cylinders 3 extend or retract, causing the placement rack 2 to move up and down, the slider 7 slides in the sliding groove 6 to ensure that the path of the placement rack 2 moving up and down is deviated. Both hydraulic telescopic cylinders 3 are connected to the hydraulic power unit 8. The hydraulic power unit 8 controls the two hydraulic telescopic cylinders 3 to extend and retract synchronously.

[0018] It should be noted that the fertigation machine used in this embodiment is a common fertigation equipment in this technical field, and its structure will not be described in detail. The model of the fertigation machine used in this embodiment is RSD-SF fertigation machine.

[0019] To enable the two hydraulic telescopic cylinders 3 to extend and retract synchronously, the hydraulic power unit 8 includes a motor-driven hydraulic oil pump 81, a hydraulic oil tank 82, and a hydraulic synchronization diverter valve 83. The hydraulic oil tank 82 is fixedly connected to the oil inlet at the upper end of the hydraulic oil pump 81, and the hydraulic synchronization diverter valve 83 is fixedly connected to the output end of the hydraulic oil pump 81. The hydraulic synchronization diverter valve 83 is connected to both hydraulic telescopic cylinders 3. The hydraulic oil tank 82 provides hydraulic oil, and the hydraulic oil pump drives the two hydraulic telescopic cylinders 3 to operate, smoothly adjusting the height of the placement frame 2. Through the hydraulic synchronization diverter valve 83, the synchronous lifting and lowering of the two hydraulic telescopic cylinders 3 is ensured.

[0020] To add and drain the fertigation solution into the fertigation tank 1, an inlet is provided at one end of the fertigation tank 1. An inlet pipe 9 is fixedly connected to the inlet. The input end of the inlet pipe 9 is connected to the output end of the fertigation machine. After the fertigation machine is turned on, the fertigation solution can be sent into the fertigation tank 1 through the inlet pipe 9. A drain outlet 10 is provided at the bottom of the fertigation tank 1. A recovery pipe 11 is fixedly connected to the drain outlet 10. The recovery pipe 11 is connected to the recovery tank. A valve is installed on the recovery pipe 11 near the drain outlet 10. Normally, the valve is closed. When it is necessary to drain the fertigation solution in the fertigation tank 1, the operator manually opens the valve to drain the fertigation solution through the recovery pipe 11. After the drainage is completed, the valve is manually closed again.

[0021] To improve the stability of the support rod 5, a support base plate 12 is fixedly connected to the bottom of the support rod 5, and the bottom of the hydraulic telescopic cylinder 3 is fixedly connected to the upper end of the support base plate 12.

[0022] To prevent the placement frame 2 from falling due to loss of support after the hydraulic telescopic cylinder 3 is depressurized, a pressure relief support column 13 is placed between the support base plate 12 and the placement frame 2 when the placement frame 2 is lifted to a high position by the hydraulic telescopic cylinder 3. Four pressure relief support columns 13 are provided. When the hydraulic telescopic cylinder 3 drives the placement frame 2 to the high position, the pressure relief support columns 13 are placed vertically between the support base plate 12 and the placement frame 2. Then, the pressure is slowly released, and the placement frame 2 slowly falls until it contacts the upper end of the pressure relief support column 13 and is supported and lifted by the pressure relief support column 13.

[0023] The specific working process of this utility model is as follows:

[0024] Place the seedling trays on the placement rack 2, connect the input end of the liquid inlet pipe 9 to the output end of the fertigation machine, start the fertigation machine, and feed the fertigation solution into the fertigation tank 1 through the liquid inlet pipe 9. When the liquid level in the fertigation tank 1 reaches two-thirds of the height inside the tank 1, turn off the fertigation machine to complete the injection of the fertigation solution. Then turn on the hydraulic oil pump 81, and control the two hydraulic telescopic cylinders 3 to extend and retract simultaneously through the hydraulic synchronous diverter valve 83. First, slowly pressurize, and the hydraulic telescopic cylinders 3 extend to support the placement rack 2. Remove the pressure relief support column 13, and then change the oil supply direction through the reversing valve to control the hydraulic extension. The hydraulic cylinder 3 retracts, and the height of the placement rack 2 gradually decreases until the bottom of the seedling trays on the placement rack 2 is immersed in the water and fertilizer solution in the water and fertilizer tank 1. The movement of the hydraulic cylinder 3 is stopped, and after about 15 minutes, the water and fertilizer irrigation of the seedling trays is completed. The hydraulic cylinder 3 is then controlled to extend and retract again, lifting the placement rack 2 and raising it away from the water and fertilizer tank 1 until the placement rack 2 is lifted to the highest position. The four pressure relief support columns 13 are then placed between the support base plate 12 and the placement rack 2, and the hydraulic cylinder 3 is slowly depressurized. The height of the placement rack 2 gradually decreases until its bottom contacts the top of the pressure relief support column 13 and is supported and lifted.
