Description

Technical Field

[0001] The utility model relates to the technical field of seedling raising equipment, in particular to a rice seedling raising device. Background Technique

[0002] Rice is one of the important food crops of mankind, and its cultivation and consumption history are quite long. Half of the world's population eats rice, mainly in Asia, southern Europe, tropical America and parts of Africa. Before planting rice, rice seeds will be subjected to seedling raising treatment. In order to ensure the normal growth of seedling raising, liquid fertilizer will be regularly added to the seedling raising box to ensure the nutrient content inside the seedling raising box.

[0003] In recent years, with the development of the economy, the emissions of industrial, agricultural and municipal domestic waste have caused increasingly serious soil heavy metal pollution and soil salinization. Agricultural product seeds are no longer suitable for direct cultivation and germination in the soil. For example, the germination of rice seeds not only requires acidic soil for the seeds to take root, but also sufficient nutrients and moisture to penetrate the seeds. The quality of the seedlings directly affects the yield of crops. Therefore, the prior art mostly uses seedling raising boxes to cultivate seedlings. Traditional seedling raising boxes are often placed statically at the bottom of the box. After seedling raising, it is necessary to continuously water and supply fertilizer to the bottom of the box. The cultivator needs to monitor the germination of the seedlings in real time, timely supplement water and nutrients, which is time-consuming and laborious, and the cultivation cost is high. Moreover, the rice seedlings in the seedling raising box are prone to lack of sunlight, thus affecting the growth of rice. Content of the Utility Model

[0004] The purpose of the utility model is to provide a rice seedling raising device to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A rice seedling raising device, comprising:

[0007] A lifting mechanism, the lifting mechanism includes a seedling raising box;

[0008] A seedling raising mechanism, the seedling raising mechanism is fixedly arranged inside the seedling raising box. The seedling raising mechanism includes a seedling raising tray. A positioning frame is fixedly connected to the top of the seedling raising tray. A plurality of positioning holes are equidistantly arranged on the seedling raising tray. A planting cylinder is slidably sleeved in the positioning holes. Two sliding seats are symmetrically and fixedly connected to the opposite side walls of the seedling raising tray. A slide rail column is slidably sleeved outside the sliding seat. A lifting seat is fixedly connected to the end of the slide rail column.

[0009] Furthermore, the lifting mechanism includes:

[0010] A protective cover, fixedly connected to the top of the seedling raising box;

[0011] The liquid inlet pipe is connected to the inside of the seedling raising box and is fixedly connected to the side wall of the seedling raising box;

[0012] The liquid outlet pipe is connected to the inside of the seedling raising box and is fixedly connected to the side wall of the seedling raising box;

[0013] The control valve is fixedly arranged on the outer wall of the liquid outlet pipe.

[0014] Furthermore, the seedling raising box includes:

[0015] There are two limiting grooves, symmetrically opened on the inner side wall of the seedling raising box;

[0016] There are two T-shaped blocks, which are slidably and embeddedly connected with the limiting grooves and are fixedly connected to the side wall of the slide rail column.

[0017] Furthermore, the lifting mechanism includes:

[0018] The screw rod is screwed to the end of the lifting seat;

[0019] The servo motor, its output end is fixedly connected to the top of the screw rod and is fixedly connected to the protective cover;

[0020] The bearing seat is fixedly sleeved on the bottom end of the screw rod.

[0021] Furthermore, the protective cover includes:

[0022] The positioning pressing plate is fixedly connected to the inner wall of the protective cover.

[0023] Furthermore, the seedling raising mechanism includes:

[0024] The liquid inlet holes are annularly and equidistantly opened at the bottom of the planting cylinder;

[0025] The embedding blocks are symmetrically and fixedly connected to the bottom end of the planting cylinder.

[0026] Furthermore, the seedling raising mechanism includes:

[0027] The sliding column is slidably connected in the lifting seat;

[0028] The pressing block is fixedly connected to the top end of the sliding column;

[0029] There are two driving rods, one end of which is rotatably connected to the pressing block and the other end is rotatably connected to the side wall of the positioning frame;

[0030] The return spring is sleeved on the outside of the sliding column and its end is fixedly connected to the pressing block.

[0031] Compared with the prior art, the beneficial effects of the present utility model are:

[0032] 1. Rice seedlings can be planted in a planting tube, and nutrient solution can be added to the seedling box through a liquid inlet pipe. The screw is driven to rotate by a servo motor, and then the lifting seat and two seedling trays are driven to descend. The vertical movement direction of the seedling tray can be limited by a T-block and a limit groove, so that the nutrient solution at the bottom of the planting tube and the bottom of the seedling box are in contact, and then the nutrient solution is absorbed by the soil in the planting tube through the liquid inlet hole, and then the servo motor drives the screw to rotate in the opposite direction, thereby driving multiple planting tubes to rise to their original positions. This solves the problem of traditional seedling boxes in the prior art, where the seedling trays are often placed statically at the bottom of the box. After seedlings are raised, water and fertilizer need to be continuously poured to the bottom of the box. The cultivator needs to check the germination of the seedlings in real time and replenish water and nutrients in time, which is time-consuming and labor-intensive, and has high cultivation costs.

[0033] 2. When the lifting seat drives the seedling trays on both sides to rise, the top pressure block will conflict with the positioning pressure plate, and then squeeze the sliding column to slide in the lifting seat, and the driving rods on both sides will be driven to rotate by the top pressure block. The ends of the driving rods will push the sliding seats on the opposite side walls of the seedling tray to slide in the slide rail columns, so that the seedling tray can be pushed out of the seedling box, which makes it easier for the rice seedlings to receive sunlight and also makes it convenient for the staff to move the planting tube with the rice seedlings out of the seedling tray.

[0042] Specifically, the rice seedlings can be planted in the planting tube 205, and the nutrient solution can be added to the seedling box 101 through the liquid inlet pipe 103. The screw 110 is driven to rotate by the servo motor 111, and then the lifting seat 109 and the two seedling trays 201 are driven to descend. The vertical movement direction of the seedling tray 201 can be limited by the T-block 107 and the limiting groove 106, so that the bottom of the planting tube 205 is in contact with the nutrient solution at the bottom of the seedling box 101, and then the nutrient solution is absorbed by the soil in the planting tube 205 through the liquid inlet hole 206, and then the servo motor 111 drives the screw 110 to rotate in the opposite direction, thereby driving multiple planting tubes 205 to rise to their original positions.

[0045] In this embodiment, when the lifting seat 109 drives the seedling trays 201 on both sides to rise, the top pressure block 209 will conflict with the positioning pressure plate 113, and then squeeze the sliding column 208 to slide in the lifting seat 109, and the driving rods 211 on both sides are driven to rotate by the top pressure block 209. The ends of the driving rods 211 will push the sliding seats 203 on the opposite side walls of the seedling tray 201 to slide in the slide rail column 108, so that the seedling tray 201 can be pushed out from the seedling box 101, which makes it easier for the rice seedlings to receive sunlight and also makes it convenient for the staff to move the planting tube 205 planted with rice seedlings from the seedling tray 201.
