TECHNICAL FIELD

[0001] The utility model relates to the technical field of corn breeding pollination, especially relates to a corn breeding artificial auxiliary pollination device. BACKGROUND

[0002] Corn belongs to root crops, and the underground nodal root is the main body of the root system, which penetrates deep into the soil. The stem is composed of nodes and internodes, which is cylindrical and hard in texture. Corn is one of the main food crops for human beings. Since corn is a monoecious plant with separate male and female flowers, it needs to be pollinated for fruiting. Pollination can be divided into natural pollination and artificial auxiliary pollination. In order to better carry out breeding, staff usually need to use tools to artificially pollinate corn. Corn artificial pollination is a key link of corn auxiliary pollination, which is usually carried out when the corn silks grow to about 5 cm.

[0003] At present, the conventional artificial pollination method usually needs to use a cloth bag to cover the male ear of corn and then shake it to obtain pollen, and then the cloth bag is connected to the outside of the corn silks for contact pollination. This single-to-single pollination method has high pollination rate and can perform pollination between plants according to needs, but the pollination tool is relatively primitive, the work efficiency is relatively low, and the pollen is easy to spill during the process of wrapping the cloth bag, causing waste. In addition, the growth height of some corn stalks is relatively high, and the position of the male ear at the top is relatively high, so it is difficult to manually hold the cloth bag to wrap it, which further affects the pollination efficiency.

[0004] The utility model aims at providing a corn breeding artificial auxiliary pollination device, which can adapt to corn plants of different growth heights for convenient ear wrapping and pollen collecting operation, and can perform integrated pollination, combining the pollen collecting step and the pollination step for continuous operation, improving the efficiency of artificial pollination and avoiding the problem of easy pollen spilling in the conventional cloth bag step-by-step operation.

[0005] In order to achieve the above object, a corn breeding artificial pollination device is provided, which comprises a handle, a barrel pipe is fixedly connected to the top of the handle, a damping sleeve is embedded and fixed to the inner top of the barrel pipe, a sliding rod is in sliding fit with the inner side of the damping sleeve, a snap ring is embedded and fixed to the lower right side of the sliding rod, a sleeve is fixedly connected to the bottom left side of the snap ring, a powder extraction pipe is in communication and fixed to the top left side of the sleeve, a small straight-through fan is in communication and fixed to the bottom end of the powder extraction pipe, a pollination pipe is in communication and fixed to the bottom output end of the small straight-through fan, and a holding pipe is in communication and fixed to the right end of the pollination pipe.

[0006] As an improvement of the utility model, the pollination pipe is made of a plastic corrugated hose; one hand holds the handle to control the sleeve to cover and shake the top layer of tassel to extract powder, and the other hand holds the holding pipe to freely extend to the middle layer to align the pistil filament for pollination.

[0007] As a further improvement of the utility model, the right end of the holding pipe is in communication and fixed with a diffusion head; the pistil is more comprehensively pollinated.

[0008] As a further improvement of the utility model, the inner left upper corner of the sleeve is provided with a filter cover, the bottom of the filter cover is arc-shaped, and the front and back sides of the filter cover are fixedly connected with the sleeve; the shaken and scattered pollen and the leaf impurities are screened and filtered to avoid affecting the pollination quality.

[0009] As a further improvement of the utility model, the left side of the small straight-through fan is fixedly connected with a fixing frame, and the left side of the fixing frame is fixedly connected with the barrel pipe; the two are integrally fixed to keep relatively stable.

[0010] As a further improvement of the utility model, the middle part of the outer side of the handle is provided with a ring groove, and an antiskid rubber sleeve is sleeved on the inner side of the ring groove; the comfort of single-handed holding is improved, and the problem of hand slipping and falling off is avoided.

[0011] As a further improvement of the utility model, an antistatic film is covered on the inner side of the sleeve; the pollen is prevented from being electrostatically adsorbed on the inner wall of the sleeve to affect the pollination amount.

[0012] In the utility model, through setting up handheld cylinder pipe cooperation damping sliding sleeve and slide bar up and down sliding fit telescopic, further can carry out lifting height's free regulation to sleeve assembled on the upper end of slide rod, can adapt to different growth height's maize plant and carry out convenient earing powder taking operation, in addition, in the sleeve top intercommunication fixed powder extraction pipe cooperation small type straight through fan and pollination tube shake off the pollen on the tassel and pump to the pollination tube export and corresponding blow to the silk of pistil and carry out integrated pollination, combine the powder taking step and the pollination step and carry out continuously, improve the efficiency of artificial pollination and can avoid the problem that the powder is easy to spill in the conventional cloth bag step operation.
