[0001] The invention relates to the technical field of seedling raising devices, in particular to a cotyledon-free grafting seedling raising device for bitter melon. Background Art

[0002] As an important vegetable crop, bitter melon is widely planted in agricultural production. Traditional bitter melon seedling raising methods have many limitations and are difficult to meet the needs of modern efficient agricultural production. In the bitter melon seedling raising process, grafting is a key technology that helps to improve the disease resistance, adaptability and yield of bitter melon.

[0003] At present, in the prior art, in terms of fixing the grafting part, traditional devices usually use simple clamps or binding methods. This fixing method is difficult to accurately control the clamping force and position. For the operation of cotyledonless grafting of bitter melon, which requires high precision, it is easy to cause damage to the grafting part due to improper clamping, affecting the healing effect and survival rate. In addition, during the seedling raising process, due to the lack of effective buffering and adaptive adjustment mechanisms, it cannot cope well with the subtle changes in the growth process of the seedlings and the vibration caused by external factors, etc., and it is easy to loosen the fixation, thereby destroying the connection stability of the grafting part.

[0016] The present invention provides a cotyledon-free grafting seedling raising device for bitter melon, which has the following beneficial effects:

[0017] (1) The bitter melon cotyledonless grafting seedling raising device has a stabilizing device, and the motor drives the threaded rod to rotate, so that the clamp moves along the threaded rod and the guide rod, and can accurately adjust the position and firmly clamp the seedling raising wound, so as to ensure that the fixed object is stable without shaking or displacement during the seedling raising period, and create a stable environment for the bitter melon cotyledonless grafting seedling raising, which is conducive to the normal growth and development of the seedlings. The screw rod, ratchet plate and other structures on the movable plate can further fine-tune the clamping force and state. The handle is turned to drive the screw rod to rotate and push the ratchet plate to move, which can adapt to stock of different sizes and shapes, and improve the versatility and flexibility of the device. The clamping structure of the ratchet plate and the clamping block, combined with the push plate, push spring and push block and other components, can achieve reliable locking after the clamping state is adjusted.

[0018] (2) The bitter melon cotyledonless grafting seedling raising device can accurately adjust the angle of the spray pipe according to the height change determined by the stabilizing device through the provided irrigation device and the coordinated action of the stabilizing device. When the motor in the stabilizing device drives the threaded rod to rotate, driving the clamp and the movable plate connected thereto to move up and down, the spray pipe is rotatably connected to the bottom surface of the movable plate, and the surface of the gear interface is meshed with the rack. The rack is displaced due to the contact between the roller and the inclined plate and the action of the spring, thereby driving the gear interface to rotate, and finally realizing the change of the spray pipe angle. In this way, the spray pipe can always be accurately aligned with the seedling raising basin, ensuring that the irrigation water flow is evenly and accurately sprinkled in the seedling raising basin, avoiding uneven water distribution caused by spray angle deviation, providing a suitable and stable water supply environment for bitter melon cotyledonless grafting seedling raising, and effectively promoting the healthy growth of seedlings.

[0019] (3) The bitter melon cotyledonless grafting seedling raising device is tightly combined with the stabilizing device through the drip irrigation device. After the clamping block completes the fixation of the rootstock, the clamping block and the steel rope are linked to realize the precise change of the drip tube angle. After the clamping block fixes the rootstock, since it is connected to the steel rope, it will pull the steel rope, and the steel rope will drive the suspension rod to move in the slideway, thereby changing the position of the connecting ring hinged to the suspension rod, so that the angle of the drip tube in the drip irrigation tank is adjusted. This design can accurately position the drip irrigation angle of the drip tube near the root system of the rootstock according to the state of the clamping block fixing the rootstock, ensure that liquids such as anti-lateral sprouting agents can accurately drip on the target position, avoid affecting the effect of the agent or causing waste due to the deviation of the drip irrigation position, effectively improve the accuracy and effectiveness of the use of the agent, and provide reliable drip irrigation guarantee for the cultivation of the rootstock in the process of bitter melon cotyledonless grafting seedling raising, which is conducive to improving the success rate and quality of seedling raising.
