Description

Technical Field

[0001] The utility model relates to a root irrigation type rice seedling raising device, belonging to the technical field of rice seedling raising devices. Background Technique

[0002] Rice, also known as paddy or rice, is an edible cereal, an annual herbaceous plant that thrives in warm and humid environments. In southern China, it is commonly called "paddy" or "millet". The dehulled grain is rice. Currently, there is no genetically modified rice in Northeast China. After being cooked, it is called cooked rice or white rice. When raising rice seedlings, a seedling raising device is needed.

[0003] According to the utility model patent with the publication number CN208175517U, a root irrigation type rice seedling raising device is provided. Two semi-cylindrical covers are clamped with each other and locked into a cylinder by a clamp to form a seedling raising cavity. The cylinder is inserted into the top of a water tank and supported by a support plate with water passing holes at the bottom of the cylinder. An absorbent sponge layer continuously replenishes water from the water tank into the cylinder through a cloth strip to promote the growth of seeds. When the seedling raising is completed, the cylinder is removed, the clamp is opened, and the left and right covers are separated, and the soil block with seedlings can be exposed, which is convenient and fast, and effectively avoids the situation of damaging the roots of seedlings due to breaking the soil. In addition, since each component of this device is detachable, it is convenient to clean. When the above device is in use, although water can be replenished, the soil humidity required by rice is different at different stages of seedling raising, but this device cannot adjust the water replenishment according to the actual situation, resulting in low practicability of the device. Content of the Utility Model

[0004] The purpose of the utility model is to provide a root irrigation type rice seedling raising device, which can conveniently adjust the device, thereby adjusting the water replenishment effect, avoiding affecting the seedling raising effect, and improving the practicability of the device, so as to solve the problems raised in the above background technique.

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

[0006] A root irrigation type rice seedling raising device includes a box body. A plurality of seedling raising grooves are arranged in an array at the top end of the box body. A cavity one is arranged inside the lower part of the box body. Liquid delivery pipes are fixedly embedded through the bottom inner walls of the seedling raising grooves.

The motor 17 and the gearbox 16 can drive the rotating shaft 11 to rotate, so that the rotating shaft 11 drives the cam 12 to rotate. When the cam 12 abuts against the top plate 10, the cam 12 will push the top plate 10 to compress the spring 18. At the same time, the top plate 10 will drive the piston 7 to move through the ejector rod 8. At this time, the inside of the pipe body 5 will be pumped to negative pressure, so that the water liquid enters the pipe body 5 through the liquid extraction pipe 6. When the cam 12 separates from the top plate 10, the spring 18 will push the top plate 10 to reset, so that the top plate 10 drives the piston 7 to reset through the ejector rod 8. Furthermore, the piston 7 will squeeze and convey the water liquid into the seedling cultivation tank 2 through the liquid delivery pipe 4. By providing the observation window 14, the water liquid condition in the first cavity 3 can be understood. By providing the support 15, the stability of the pipe body 5 can be improved.
