Description

Technical Field

[0001] The utility model relates to the field of spraying devices, in particular to a spraying device for tobacco planting. Background Art

[0002] Tobacco cultivation is an agricultural production activity that involves selecting tobacco varieties suited to local climate and soil conditions, raising seedlings (including conventional and floating methods), transplanting, field management (including fertilization, irrigation, weeding, and pest control), harvesting at maturity, and drying or curing. The harvest is then processed into tobacco leaves for use in various tobacco products, including cigarettes, pipe tobacco, and cigars. Tobacco cultivation requires sprayers, primarily because tobacco is susceptible to various pests and diseases during its growth process, which can seriously affect its yield and quality. To effectively control pests and diseases and improve tobacco yield and quality, tobacco farmers use sprayers to apply pesticides or plant growth regulators. Sprayers evenly apply pesticides to tobacco plants, thereby controlling pests and diseases and promoting growth.

[0003] In the prior art, a Chinese utility model patent with publication number "CN214629368U" and patent name "A spraying device for tobacco planting" discloses a spraying device. The patent records technical solutions such as "the hose is fixedly mounted on the reel, and the hose is connected to the cavity. The nozzle is provided at one end of the hose, which can spray medicine over a long distance and is suitable for large-scale planting. The reel is slidably mounted on the connecting pipe, and the guide rod is fixedly mounted on the bottom plate. The guide rod is slidably connected to the hose, and the hose can be reeled in and arranged during reeling, so that the hose is neatly reeled and prevented from tangling."

[0004] However, when the spraying device is used for spraying during tobacco planting, the spraying operation still needs to be manually performed. During spraying, the worker pulls the hose to a specified length and moves the hose to the specified position. The worker then needs to hold the hose and aim it at the spraying area to spray the tobacco in the planting area. The spraying distance is limited by the length of the hose. When the spraying position exceeds the hose, the entire device needs to be moved again, resulting in a time-consuming and labor-intensive operation. In addition, the spraying operation can only be performed in one direction at a time, which not only reduces the spraying efficiency but also reduces the practicality of the spraying device.

[0005] Therefore, in order to solve the above technical problems, the utility model proposes a spraying device for tobacco planting. Utility Model Content

In this way, the spray pipe 17 can be placed above the tobacco planting area, and in this way, the spray pipe 17 can be stored when not in use. When the staff uses the handle 4 and cooperates with When the universal wheels 3 installed at the four corners of the bottom surface of the movable base 1 push the entire device to move in the gaps between the tobacco planting areas, the pump body 19 will extract the liquid medicine added to the liquid medicine tank 5 through the liquid filling port 6 through the liquid outlet pipe 7 installed at the bottom of the rear end of the liquid medicine tank 5 through the connecting pipe 20 installed on the input end, and transport the extracted liquid medicine to the three-way valve 21 installed on the output end. The liquid medicine will then pass through the three-way valve 21 and enter the delivery hose 22 through the output ends at both ends, and then be transported to the spraying pipe 17 through the delivery hose 22. Finally, After unfolding, several nozzles 18 installed on the bottom of the spray pipe 17 spray the liquid medicine onto the tobacco in the planting area, and as the device continues to move, the spraying operation can be completed on the tobacco in the planting areas on both sides at the same time. Therefore, by moving the spraying mechanism 2 in the gap between the planting areas, the purpose of automatic spraying of tobacco in the planting areas on both sides can be achieved at the same time. The staff only needs to push the entire equipment to move, and no manual operation is required to spray. The spraying operation is simple and convenient, and the spraying range is large, which not only improves the spraying efficiency during tobacco planting, but also improves the practicality of the device.
