[0032] Before introducing the technical solutions of the present application, it is necessary to explain the background of the present application. As is generally known, the existing seedling raising device is mostly used for cultivating seedlings through a container, and the medium for cultivation is usually seedling soil or humus soil. In the cultivation process, the seedlings need to be irrigated, and a drainage hole is usually provided at the bottom of the container for draining excess water. However, when the soil moisture content is too high, the drainage through the drainage hole is relatively slow, and most of the water will remain in the soil for a long time. It is difficult to observe whether the soil moisture content is appropriate by naked eye, and the excessively wet soil will lead to insufficient oxygen supply in the soil, thereby affecting the respiration of the seedlings, causing the seedlings to lack oxygen, or causing the roots to rot, thereby affecting the ability of the seedlings to absorb water and nutrients. In view of this, the present application aims to provide a seedling raising device with improved drainage performance.

[0033] Referring to Figures 1 to 5 The utility model exemplary embodiments provide a kind of seedling raising device of improving drainage performance, including the seedling raising device of improving drainage performance of the utility model, including the fixed support 1 with containing cavity, the pressure sensing device being located in containing cavity, the planting dish 2 being located in the top of pressure sensing device, and the water absorption component being located in containing cavity and being liftable;Wherein, user fills and plants seedling in the inside of planting dish 2 with soil, planting dish 2 and bottom are provided with two groups of drainage holes 21 relatively, water absorption component top includes two groups of water absorption layer 31 corresponding with drainage hole 21, water absorption layer 31 is driven to extrude into drainage hole 21 when water absorption component rises. The parts of this seedling raising device will be described as follows:

[0034] Pressure sensing device: referring to Figures 1 to 5 This pressure sensing device includes pressure sensor 41 for measuring the total weight in the planting dish 2, and signal processing unit 42 for analyzing the total weight signal received from the pressure sensor 41. It should be understood that the planting dish 2 will generate pressure on the pressure sensor 41, so that the total weight of the planting dish 2, soil and seedlings can be measured by the pressure sensor 41. Thus, the specific method of soil moisture detection is as follows: first, record the initial total weight by pressure sensor 41: after watering, wait for the seedlings to gradually absorb water and the soil surface to start to dry, record the dry total weight by pressure sensor 41 again, compare the initial total weight and the dry total weight, you can roughly understand the water content in the soil, if the weight exceeds obviously, it indicates that the soil is too wet.

[0035] Water absorption component: referring to Figures 1 to 5The water absorption assembly comprises a hydraulic lifting push rod 32 arranged at the bottom of the accommodating cavity and connected with the signal processing unit 42, and opposite two groups of supporting rods 33 are arranged at the extending end of the hydraulic lifting push rod 32 in the horizontal direction, and a mounting plate 34 is arranged at the top of the end of the supporting rod 33, and the water absorption layer 31 is arranged on the mounting plate 34, preferably, the bottom of the water absorption layer 31 is attached to the mounting plate 34, so as to facilitate the replacement of the water absorption layer 31 in the later period. It should be noted that the structure of the hydraulic lifting push rod 32 comprises an actuator, i.e. an oil cylinder, a hydraulic control valve group and an oil pump motor and the like, wherein the supporting rod 33 is arranged at the end of the piston of the oil cylinder, and therefore, when the piston of the oil cylinder moves, the supporting rod 33, the mounting plate 34 and the water absorption layer 31 thereon will move synchronously. Specifically, when the pressure sensing device detects that the soil is in excessive wetting, the signal processing unit 42 is connected with the hydraulic lifting push rod 32 through signal connection, and the hydraulic lifting push rod 32 is driven to move upward by the hydraulic control valve group, so as to drive the piston of the oil cylinder to move upward, and at the same time, the water absorption layer 31 is lifted to be squeezed into the drainage hole 21 to perform the water absorption function, thereby improving the drainage efficiency of the soil in the planting dish 2. When the pressure sensing device detects that the soil returns to the normal wetting range, the signal processing unit 42 controls the hydraulic lifting push rod 32 to drive the water absorption layer 31 to reset. As a preferred technical solution, the water absorption layer 31 is made of flexible porous material, for example, the sponge can be used to make the water absorption layer 31.

In addition, it should be noted that when the two groups of isolation plates 54 move away from each other, the isolation plate 54 can move to the top of the water absorption layer 31 to completely cover the water absorption layer 31.

[0041] Specifically, the two groups of isolation plates 54 hover above the two groups of water absorption layers 31 in the normal state, and during normal irrigation, the water flowing out of the drainage hole 21 will drip above the isolation plate 54, and through the inclined surface of the isolation plate 54 and the drainage groove opened on the surface, the water can be drained to the outside of the fixed support 1, avoiding the water from wetting the water absorption layer 31 in advance, and ensuring the water absorption effect of the water absorption layer 31 during use; when the pressure sensing device detects that the soil is in excessive wetting, the user can start the driving motor 51 to drive the gear 52 to rotate, and through the gear 52, a pair of racks 53 are moved in the direction of moving close to each other, thereby driving the two groups of isolation plates 54 to move close to each other and away from the top of the water absorption layer 31, providing space for the subsequent lifting of the water absorption layer 31; after the water absorption layer 31 is reset, the user can control the two groups of isolation plates 54 to reset again through the driving motor 51, that is, to return to the top of the water absorption layer 31, at this time, the user can start the hydraulic lifting push rod 32 again to lift, so that the water absorption layer 31 is pressed by the flat surface at the bottom end of the isolation plate 54, and through the pressing, the water absorbed in the water absorption layer 31 can be quickly drained, so as to facilitate the water absorption layer 31 to be used in the next time in the most dry state. Therefore, the present application has the dual effects of accelerating the drainage of the water absorption layer 31 and drying the water absorption layer 31 again.
