Description

Technical Field

[0001] The present invention relates to the technical field of vegetable planting, and particularly to a seedling cultivation device for vegetable planting. Background Art

[0002] Vegetables are one of the essential foods in people's daily diet. Vegetables can provide various vitamins and minerals and other nutrients necessary for the human body. In order to improve the survival rate of vegetables, when planting vegetables, the vegetable seedlings need to be intensively cultivated until they grow up and then transplanted. When cultivating vegetable seedlings, generally, the vegetable seedlings are placed in a breeding box for cultivation. By placing soil matrix and supplemented with temperature control, adjusting the lighting duration, fertilizing and watering, etc., the rapid cultivation of vegetable seedlings is completed.

[0003] The existing manual watering method is difficult to evenly and accurately water each seedling, and the control of watering time and watering amount depends entirely on the subjective judgment of the planter, and cannot be adjusted in real time according to the actual water demand of the seedlings. This not only wastes water resources, but also may affect the healthy growth of seedlings due to improper watering. In summary, it is of great practical significance to develop a seedling cultivation device for vegetable planting that can accurately monitor environmental parameters and realize intelligent watering. Summary of the Invention

[0004] Based on the technical problems existing in the prior art, the present invention proposes a seedling cultivation device for vegetable planting.

[0005] A seedling cultivation device for vegetable planting proposed by the present invention includes a seedling raising box. A water storage chamber and a seedling raising chamber are provided in the seedling raising box. A plurality of lighting lamps and heaters are installed in the seedling raising chamber. A plurality of seedling raising components are arranged vertically in the seedling raising chamber. A temperature acquisition module, a humidity acquisition module, a control module and an actuator are also provided on the seedling raising box. The temperature acquisition module is used to obtain the temperature in the seedling raising chamber in real time. The humidity acquisition module is used to obtain the humidity of the seedling raising soil in real time. The actuator is used to water the seedlings. Put the seedlings into the seedling raising components, and then they can be cultivated in the seedling raising chamber. Light can be generated by the lighting lamps, and the environmental temperature in the seedling raising chamber can be adjusted by the heaters. During the cultivation process, the control module will receive the data collected by the temperature acquisition module and the humidity acquisition module in real time, and conduct comprehensive analysis, and then generate an evaluation coefficient. By comparing the evaluation coefficient with a preset evaluation coefficient reference threshold, it is judged whether the water content of the soil is within a reasonable range, and the working state of the actuator is controlled according to the comparison result. If the water content of the soil is not within a reasonable range, the actuator will be started to water the seedlings, thereby realizing intelligent watering.

[0006] Preferably, the seedling raising component includes a frame and a seedling raising tray. A plurality of notches are formed at the top of the seedling raising tray. The seedling raising tray is inserted into the top of the frame. A plurality of push columns capable of being inserted into the corresponding notches are arranged on the inner bottom wall of the frame. An elastic connection is formed between the seedling raising tray and the frame. In this way, the seedlings together with the soil substrate can be placed into the corresponding notches for cultivation. Then, after the seedlings are cultivated, only need to press down the seedling raising tray, and then the push columns will push the seedlings together with the soil substrate out of the notch, so as to facilitate the complete extraction of the seedlings and avoid damage during extraction.

[0007] Preferably, springs are respectively fixed at the corners of the bottom of the seedling raising tray. The bottom ends of the springs are fixedly connected to the inner bottom wall of the frame. In this way, the seedling raising tray can be elastically supported by the springs, so that there is space for cultivating seedlings in the notches.

[0008] Preferably, a plurality of sliding strips are respectively fixed on the inner walls of both sides of the seedling raising chamber. Sliding grooves for inserting the sliding strips are respectively formed on both sides of the frame. In this way, the whole seedling raising component can be conveniently taken out of the seedling raising chamber.

[0009] Preferably, the temperature acquisition module is fixed on the inner wall of the seedling raising chamber, the humidity acquisition module is embedded at the top of one of the push columns, and the control module is fixed on the top of the seedling raising box. In this way, the temperature acquisition module can better detect the environmental temperature in the seedling raising chamber, and the humidity acquisition module can better detect the humidity of the soil.

[0010] Preferably, the actuator includes a watering component and a transverse movement component. The watering component includes a water pump fixed on the bottom wall of the water storage chamber. A shunt pipe is arranged in the seedling raising chamber. The water outlet end of the water pump is connected with a water inlet pipe. The other end of the water inlet pipe extends into the seedling raising chamber and is connected with the shunt pipe. A plurality of spray heads are respectively connected to the shunt pipe through a plurality of hoses. The spray heads are located above the corresponding seedling raising components. An electromagnetic valve is installed on the water inlet pipe. The transverse movement component includes a plurality of screw rods and guide columns respectively located above the corresponding seedling raising components. The screw rods are rotatably connected to the seedling raising box. The screw rods are threadedly connected to the spray heads. The guide columns pass through the guide sleeves at the top of the spray heads. A plurality of screw rods are connected through a transmission structure. A motor is fixed on the outer wall of one side of the seedling raising box. The output shaft of the motor is fixedly connected to the end of the corresponding screw rod. After receiving the watering instruction issued by the control module, the water pump, the electromagnetic valve and the motor will be started simultaneously. The water pump will pump the water in the water storage chamber into the water inlet pipe, and then the water will enter the shunt pipe, the hose and the spray head in sequence. At the same time, the output shaft of the motor drives the corresponding screw rod to rotate forward and backward once, and then through the action of the transmission structure, a plurality of screw rods will rotate simultaneously. Under the guiding action of the guide columns and the guide sleeves, the screw rods will drive the spray heads to move back and forth once, so as to water the seedling raising tray comprehensively through the spray heads.

[0011] Preferably, the transmission structure includes a synchronous pulley and a synchronous belt. Two synchronous belts are respectively fixedly sleeved on the ends of the screw rods. The two adjacent synchronous pulleys up and down are connected together by the synchronous belt, and the two adjacent synchronous belts are staggeredly distributed. In this way, through the transmission cooperation between the synchronous pulley and the synchronous belt, multiple screw rods can rotate synchronously.

[0012] Preferably, a liquid level acquisition module is fixed on the side wall of the water storage chamber. A water supply pipe communicating with the water storage chamber is arranged on the side of the seedling raising box, and an alarm module is fixed on the top of the seedling raising box. When the water level in the water storage chamber drops to the position of the liquid level acquisition module, the liquid level acquisition module will detect the liquid level signal, then send the liquid level signal to the control module, and then the control module will send an alarm signal to the alarm module, and the alarm module will give an alarm, so as to remind the staff to add water to the water storage chamber in time through the water supply pipe.

[0013] Preferably, the calculation formula of the evaluation coefficient is

[0014]

[0015] Wherein, (Soil saturated water content), (Effective regulation range), C (Minimum temperature for seedling growth), C (Temperature regulation span), is the percentage of soil volume water content, is the environmental temperature in the seedling raising room.

[0016] Preferably, the control logic of the control module for the working state of the actuator according to the comparison result is as follows:

[0017] When K>1.2 and the soil humidity <85%, the actuator starts to water the seedlings.

[0018] Compared with the prior art, the present invention provides a seedling cultivation device for vegetable planting, which has the following beneficial effects:

[0019] 1. A seedling cultivation device for vegetable planting. In the present invention, the temperature acquisition module obtains the temperature in the seedling cultivation room in real time, and the humidity acquisition module obtains the humidity of the seedling cultivation soil in real time, and transmits the data to the control module. The control module generates an evaluation coefficient based on the evaluation coefficient calculation formula, comprehensively considering multiple factors such as the saturated water content of the soil, the effective regulation range, the minimum temperature for seedling growth, the temperature regulation span, the percentage of soil volume water content, and the environmental temperature in the seedling cultivation room. Then, by comparing with the preset reference threshold, it accurately judges whether the soil water content is within a reasonable range. When the environmental temperature is too high or too low, it can be adjusted in time through the heater; when the soil humidity is unreasonable, it can control the actuator to perform watering operations in time, creating a stable and suitable environment for seedling growth, greatly improving the survival rate and growth quality of the seedlings.

[0020] 2. A seedling cultivation device for vegetable planting. The seedling cultivation component adopts the design of a frame and a seedling tray. Multiple notches are opened at the top of the seedling tray, and push columns that can be inserted into the notches are provided on the inner wall of the bottom of the frame. The seedling tray and the frame are elastically connected by springs. After the seedlings are cultivated, simply press down on the seedling tray, and the push columns can push the seedlings together with the soil matrix out of the notches, avoiding damage to the seedling roots by the traditional seedling taking method, ensuring the integrity of the seedlings during transplantation, improving the survival rate of the seedlings after transplantation, and at the same time reducing the labor intensity of the planters and improving work efficiency.

[0021] 3. A seedling cultivation device for vegetable planting. The actuator is composed of a watering component and a transverse movement component. The watering component pumps the water in the water storage chamber through the water inlet pipe, the shunt pipe and the hose to the nozzle through the water pump to water the seedling tray, and an electromagnetic valve is installed on the water inlet pipe to control the on-off of the water flow. The transverse movement component uses a motor to drive the screw to rotate. Through the transmission structure of the synchronous pulley and the synchronous belt, multiple screws rotate synchronously. Under the guiding action of the guide post and the guide sleeve, the nozzle is driven to move back and forth, realizing comprehensive and uniform watering of the seedling tray. This design can not only water accurately according to the actual water demand of the seedlings, avoid waste of water resources, but also ensure that each seedling can obtain sufficient and uniform water supply, promoting the healthy growth of the seedlings.
