Description

Technical Field

[0001] This utility model relates to the field of agricultural planting technology, specifically to an agricultural planting spraying device. Background Technology

[0002] In agricultural planting, pesticide spraying is a crucial step in controlling pests and diseases and promoting healthy crop growth. However, traditional agricultural spraying equipment has several problems. First, the spraying coverage is limited, making it difficult to meet the needs of large-scale farmland operations. Most traditional equipment has fixed nozzle positions, making it impossible to flexibly adjust the height and angle, resulting in some areas not being sprayed and affecting the control effect. Second, pesticides are not mixed evenly. If pesticides are not thoroughly mixed in the tank, the concentration will be inconsistent, which not only reduces the efficacy but may also damage crops due to excessively high local concentrations. With the development of large-scale and modern agriculture, the demand for efficient, precise, and convenient agricultural spraying equipment is becoming increasingly urgent, making the development of new equipment imperative.

[0021] By adopting the above technical solution, the first motor 18 is started, which drives the main gear 19 to rotate. The main gear 19 drives the secondary gear 20 to rotate, causing the screw 17 to rotate. Under the action of the screw 17, the slider 7 moves up and down in the groove 6 of the column 5, realizing the flexible adjustment of the height of the nozzle frame 15. It can adjust the nozzle frame 15 to a suitable height according to the height of different crops and actual operation needs, thereby improving the accuracy and adaptability of spraying operations.

[0022] In this embodiment, the conveying assembly includes a water pump 21 mounted on the frame 1. The input end of the water pump 21 is connected to the bottom of the medicine tank 4, and the output end is connected to a pair of conveying pipes 22 via a three-way connector. The end of the pair of conveying pipes 22 away from the three-way connector is connected to a pair of nozzle frames 15.

[0023] By adopting the above technical solution, the water pump 21 is started, and the water pump 21 draws out the pesticide from the pesticide tank 4 and delivers it to the nozzle frame 15 through the three-way connector and the delivery pipe 22, ensuring that the nozzle can continuously spray pesticides and guaranteeing the continuity and efficiency of the spraying operation.

[0024] In this embodiment, the stirring assembly includes a second motor 23 located at the top of the medicine tank 4.

[0029] By adopting the above technical solution, the pusher 26 facilitates the operator's control of the equipment movement, reduces labor intensity, and improves work efficiency.

[0030] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0031] Example: During operation, pesticide is added to the pesticide tank 4, and an appropriate amount of water is added through the inlet. The second motor 23 is started, causing the stirring component to stir the pesticide and water in the pesticide tank 4 to ensure even mixing. Depending on the height of the crop, the first motor 18 is started, driving the main gear 19 to rotate. The main gear 19 drives the secondary gear 20 to rotate, causing the screw 17 to rotate. Under the action of the screw 17, the slider 7 moves up and down along the groove 6 of the column 5, adjusting the nozzle frame 15 to a suitable height. The water pump 21 is started, drawing out the evenly mixed pesticide from the pesticide tank 4 and conveying it to the nozzle frame through the T-connector and the delivery pipe 22. 15. Spraying from the spray head 16, pesticides are sprayed onto the crops on both sides. Simultaneously, the reciprocating push rod 11 is activated. The telescopic end of the reciprocating push rod 11 pushes the drive frame 12 to move up and down reciprocally. The racks 13 on both sides of the drive frame 12 mesh with the transmission gears 10 on the main shaft 9, causing the main shaft 9 to rotate reciprocally. This, in turn, drives the spray head frame 15 to swing reciprocally through the connecting rod 14. This swinging spraying improves the uniformity of spraying and increases the spraying range. During the spraying process, the operator can push the push handle 26 to control the movement of the equipment. After the spraying operation is completed, the water pump 21, the first motor 18, the second motor 23, and the reciprocating push rod 11 are turned off. The equipment is cleaned and moved to the designated location for storage.
