Description

Technical Field

[0001] The utility model relates to the technical field of corn planting, in particular to a pesticide spraying device used for corn planting. Background Art

[0002] Corn is a common crop. It is also the main raw material for industrial alcohol and liquor. Corn has strong adaptability and is not demanding on the soil, but it is afraid of waterlogging. Therefore, it is necessary to choose high-lying and well-drained land for cultivation. In order to increase corn yields, it is best to prepare the land before planting. During the planting process, the corn can be sprayed agriculturally according to the needs.

[0003] When using an existing pesticide sprayer, a motor-driven extraction pump is usually used to extract the pesticide solution in the pesticide container, and finally an atomizing nozzle connected by a pipe is used to spray the solution onto the corn crop and its surroundings to achieve the effect of spraying the pesticide sprayer device. For example, the corn planting pesticide sprayer device disclosed in application number CN201821928644.7 includes a bottom plate, a shock-absorbing groove is connected to the right side of the top of the bottom plate, and shock-absorbing supports are symmetrically connected to the left and right sides of the bottom of the inner cavity of the shock-absorbing groove; however, in the above technology, the direction of the nozzle is fixed, so that during the spraying operation, it is impossible to achieve the effect of full coverage of the corn crop and its surroundings with pesticide spraying, which reduces the effect of the pesticide spraying operation.

[0004] After searching, the existing patent: Corn planting pesticide sprayer device (application number: CN202222441527.0) includes a body component and a spraying mechanism, a mixing component assembled with bolts is arranged above one end of the body component, and a spraying mechanism connected to the mixing component is arranged above the other end of the body component, and the spraying mechanism includes a rear side frame; the utility model mainly utilizes the output end shaft of the driving motor driven by the mixing component to transmit power by a pulley group, so that the pulley group transmits power to the transmission wheel groups on both sides of the spraying mechanism, so that a plurality of sets of parallel distributed rotating seats and nozzles are arranged under the side horizontal bar connected to the output end of the transmission wheel group, so that after the second motor drives the pump body to extract liquid, the pesticide liquid is sprayed out through the nozzle with a rotating effect, thus avoiding the spraying operation of the nozzle with a fixed direction, achieving the effect of covering spraying in a large range, and ensuring the operation effect of pesticide spraying.

[0005] Although the above patent sprays the pesticide liquid in a rotating effect through the nozzle, thus avoiding the spraying operation of the nozzle in a fixed direction, achieving the effect of covering the spraying over a large area and ensuring the operation effect of the pesticide spraying, when the device is in use, when the height of the corn to be sprayed with pesticides is different, the height of the spraying device cannot be adaptively adjusted, which makes the device have certain limitations when operating and is inconvenient for users to use. Therefore, it is necessary to invent a pesticide spraying device for corn planting to solve the above problems. Utility Model Content
