Description

Technical Field

[0001] This utility model relates to the field of agricultural spraying technology, and more specifically to a cotton pesticide spraying device. Background Technology

[0002] In cotton cultivation, pesticide application is a crucial step in controlling pests and diseases and increasing yield. Currently, the mainstream spraying methods still rely on tractor-mounted sprayers or high-clearance self-propelled boom sprayers. These methods work by pressurizing the pesticide solution with a pump and then atomizing it evenly through horizontal or slightly downward-sloping nozzles, relying on natural wind or mechanical air delivery to deliver the pesticide particles to the cotton canopy. However, once cotton plants enter the flowering and boll-forming stage, their height generally exceeds 1.2 meters, with intertwined branches and leaves and a dense canopy. Traditional horizontal or slightly downward spraying methods can only cover the upper surface of the leaves, leaving the undersides of leaves, the lower and middle parts of the stems, and areas hidden by buds and bolls untreated. Furthermore, due to the obstruction of the cotton canopy, a large number of atomized particles bounce off the leaf surface or escape into the air with rising air currents, resulting in pesticide waste and environmental pollution risks.

[0003] To improve pesticide application rates on the undersides and lower parts of leaves, some growers increase spray pressure, pesticide concentration, or the number of nozzles. However, these methods often result in excessive instantaneous liquid volume on the leaves, causing pesticide to roll off and exacerbating pesticide loss, and can easily induce phytotoxicity. Another approach involves adding reflectors below the nozzles to deflect some droplets onto the undersides of the leaves. However, the fixed reflection angle cannot adapt to the spatial differences in cotton plants with varying row spacing and growth stages. The deflection effect significantly diminishes as the plant grows, making it difficult to consistently improve pesticide application rates on the undersides of leaves.

[0004] Therefore, how to provide a new cotton pesticide spraying device that can ensure pesticide coverage on the underside of cotton leaves while reducing pesticide waste is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention provides a cotton pesticide spraying device, which aims to solve the technical problems of low coverage on the back of cotton leaves during the traditional cotton pesticide spraying process, and serious waste of pesticide solution caused by trying to achieve the coverage on the back of cotton leaves.

[0006] A cotton pesticide spraying device, mounted on a suspension located at the rear of a pesticide spraying agricultural machine, includes:

[0007] The upright plate is arranged vertically along the forward direction of the spraying machine and its top is elastically connected to the suspension.

[0008] The liquid spray nozzle is detachably connected to the bottom surface of the vertical plate, and the spray direction of the liquid spray nozzle is arranged obliquely upward.

[0009] The air nozzle is installed on the side of the vertical plate where the liquid medicine nozzle is installed, and above the liquid medicine nozzle. The air nozzle is arranged to spray diagonally downwards.

[0010] Through the above technical solution, this utility model arranges pesticide spray nozzles on the surface of the upright plate near its bottom end, with the spray direction of the pesticide spray nozzles being obliquely upward. This allows for pesticide spraying coverage on the back of cotton leaves during the spraying process. Since the oblique upward spraying process involves spraying the atomized pesticide from low to high, the atomized pesticide is more likely to disperse in the air after passing through the gaps between the cotton leaves, resulting in pesticide waste. To address this, this utility model uses an air nozzle located above the pesticide spray nozzle and its oblique downward spray direction to allow the floating atomized particles to return to the cotton leaf layer under the influence of airflow and adhere to the surface of the cotton leaves. This design features pesticide spraying on the back of cotton leaves and reduces the waste of floating pesticide atomized particles.

[0011] Preferably, during the pesticide application process, the pesticide spray nozzle is positioned below the cotton canopy branches and leaves, and the intersection of the spray direction of the air nozzle and the spray direction of the pesticide spray nozzle is located above the cotton canopy branches and leaves.

[0012] Preferably, it also includes a spring, the top end of which is fixedly connected to the suspension, and the bottom end of which is fixedly connected to the top end of the upright plate.

[0013] Preferably, the upright plate is an arc-shaped plate with its axis arranged parallel to the height direction of the spraying machine. The concave surface of the upright plate faces the rear of the spraying machine, and the liquid spray head and air spray head are installed on the concave side of the upright plate.

[0014] Preferably, there are two liquid spray nozzles, arranged at an angle between them.

[0015] Preferably, it also includes a liquid distribution pipe. An installation hole is provided on the surface of the upright plate near its bottom end. The first end of the liquid distribution pipe passes through the installation hole and is securely connected to the installation hole. The second end of the liquid distribution pipe has two branch pipes arranged at an angle, and the two liquid spray nozzles are detachably connected to the ports of the two branch pipes respectively.

[0016] Preferably, it also includes an elbow, which is detachably connected to the first end of the separatory tube.

[0017] Preferably, it also includes a connecting bend, and the upright plate is provided with a second mounting hole above the first mounting hole. The first end of the connecting bend passes through the second mounting hole and is fastened to the second mounting hole. The air nozzle is detachably connected to the first end of the connecting bend.

[0018] Preferably, it also includes an air line connector, which is detachably connected to the second end of the connecting bend.

[0019] Preferably, the air nozzle is a flat-head type air nozzle.

[0020] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a cotton pesticide spraying device, which has the following beneficial effects: by combining the upward-sloping liquid spray nozzle and the downward-sloping air spray nozzle, the back of the cotton leaf can be effectively covered, and the airflow is used to guide the floating liquid particles back to the cotton leaf layer, thereby improving the pesticide application rate and reducing liquid waste.
