Description

TECHNICAL FIELD

[0001] The utility model belongs to tobacco technical field, and concretely relates to a tobacco insecticidal spraying device. BACKGROUND

[0002] Tobacco insecticidal refers to the process of controlling and eliminating pests that harm the growth of tobacco in the process of tobacco planting. The types and harms of tobacco pests: tobacco aphid is one of the most common pests on tobacco, with small individual and strong reproductive capacity. It sucks the sap of tobacco leaves, tender stems and flower buds with piercing-sucking mouthparts. It causes tobacco leaves to curl and turn yellow, and hinders growth. At the same time, tobacco aphid can also transmit a variety of viral diseases, such as cucumber mosaic virus (CMV), which can further seriously affect the quality and yield of tobacco. The tobacco armyworm (tobacco budworm) larva is relatively large in size and color, usually green or brown. It mainly moves at night and has phototaxis. Its larvae eat tobacco leaves, tender stems and flower buds, causing holes and notches in the leaves, and even cutting off the tender stems, which can cause great damage to the yield and quality of tobacco. The adult of the tobacco cutworm has strong phototaxis and chemotaxis, and the larva has a large food intake. The tobacco cutworm larva can eat all the leaves and only leave the leaf veins, which can cause devastating damage to tobacco in a short time.

[0003] The traditional insecticidal spraying method has uneven spraying coverage, which can cause some tobacco plants to be unprotected and make pests breed and spread. CONTENT

[0004] Therefore, the utility model provides a tobacco insecticidal spraying device, which aims at solving the problem of uneven spraying coverage of the traditional insecticidal spraying method, which can cause some tobacco plants to be unprotected and make pests breed and spread.

The liquid spraying nozzle is provided with a plurality of liquid spraying nozzles. The spraying device body is in a cylindrical structure. The hollow inner cavity is arranged on the spraying device body. The liquid inlet is arranged at one end of the hollow inner cavity and communicates with the inner cavity. The liquid spraying nozzles are arranged along the side surface of the spraying device body in a ring shape. The liquid spraying nozzles communicate with the hollow inner cavity.

[0007] On the basis of the above technical scheme, the tobacco insecticidal spraying device of the utility model can be further improved as follows:

[0008] The other end of the spraying device body is provided with the fixed support, and the fixed support comprises the telescopic rod with adjustable length.

[0009] Further, the liquid spraying nozzles on the spraying device body are uniformly distributed along the side surface of the spraying device body, and the spray opening of the liquid spraying nozzle is in a horn shape.

[0018] The stirring mechanism in the hollow inner cavity can fully mix the insecticide with the diluent, the flow regulating valve at the liquid inlet can accurately control the spraying flow according to the actual insect damage, the insecticide effect can be ensured, the waste of the insecticide can be avoided, the resource utilization rate is improved, the cost is reduced, and the pollution to the environment is reduced.

[0019] The anti-corrosion coating on the surface of the spraying device body can effectively resist the corrosion of the insecticide, reduce the damage and maintenance frequency of the device, prolong the service life of the spraying device, reduce the long-term use cost, and ensure the continuity and stability of the insecticide operation.

[0020] The detachable liquid spraying nozzle structure is convenient to clean, replace and maintain, can ensure that the liquid spraying nozzle is always in a good working state, reduce the abnormal spraying caused by the liquid spraying nozzle failure, and improve the reliability of the device.

[0021] It can solve the problem of uneven spray coverage caused by traditional insecticide spraying methods, which easily leads to some tobacco plants not being effectively protected, allowing pests to breed and spread. Attached Figure Description
