Abstract
Description
Technical Field
[0001] This application relates to the field of agricultural spraying technology, and more specifically, to a multi-nozzle agricultural spraying device. Background Technology
[0002] During agricultural planting, pesticides are sprayed according to the growth of crops. Traditional backpack sprayers require manual labor to carry the sprayer, which is labor-intensive. Currently, by mounting the sprayer on a cart and moving it along the field, the labor intensity can be greatly reduced. An existing agricultural spraying device (publication number CN220654536U) allows for adjusting the nozzle height and moving it left and right. Adjusting the nozzle height ensures that the spray solution covers all parts of the crop, improving the uniformity and coverage of the spray, thus enhancing the spraying effect. However, the inventor believes that the above-mentioned technology still has the following drawbacks: When using the spraying device in the literature, the spacing between crops changes, and the roller structure of the cart is not adapted to the crop spacing, easily crushing the crops. Furthermore, the fixed spacing between multiple nozzles means that some pesticides cannot be accurately sprayed onto the crops, leading to pesticide waste. Therefore, we propose a multi-nozzle agricultural spraying device. Utility Model Content
[0003] 1. Technical problems to be solved
[0004] The purpose of this application is to provide a multi-nozzle agricultural spraying device that solves the technical problems in the prior art, such as the changing spacing between crops, the roller structure of the trolley not adapting to the crop spacing, easily crushing the crops, and the fixed spacing of multiple nozzles, resulting in some pesticides not being accurately sprayed onto the crops, leading to pesticide waste. The new device achieves this by allowing the spacing of two supports mounted on an H-shaped frame to be adjusted via bidirectional screws, enabling the rollers and soil-breaking gears mounted on the supports to move along the crops. A limiting clamp fixed at each joint of the hose slides horizontally along the cross plate via a locking bolt and is locked with a locking nut, allowing for free adjustment of the nozzle spacing to adapt to changes in crop spacing, ensuring precise pesticide spraying and effectively saving pesticide usage.

[0025] The present application will be further described in detail below with reference to the accompanying drawings.
[0026] Reference Figures 1 to 4This application provides a multi-nozzle agricultural spraying device, comprising: an H-shaped frame 1, with two supports 2 slidably mounted on the bottom of the H-shaped frame 1, the supports 2 being threadedly connected to a bidirectional screw 3, and each support 2 having a roller 21 and a soil-breaking gear 22 rotatably mounted on a shaft; four feet 11 fixedly mounted on the H-shaped frame 1, and a medicine tank 4 being mounted on the H-shaped frame 1 through the four feet 11; a spraying mechanism 5 being mounted at the bottom of the medicine tank 4, the spraying mechanism 5 including an electric pump 51, the electric pump 51 being fixedly mounted at the bottom of the medicine tank 4 and connected to it through a pipe; the electric pump 5... 1. A liquid outlet pipe 52 is fixedly connected to the bottom of the liquid outlet pipe 52, and a flexible hose 56 is threadedly connected to the bottom of the flexible hose 56. Multiple connectors 57 are provided on the flexible hose 56, and nozzles 58 are threadedly installed at each connector 57. A horizontal plate 53 is detachably installed at the bottom of the H-shaped frame 1. A limiting clamp 54 is fixedly fitted at each connector 57 of the flexible hose 56. A locking bolt 55 is threadedly installed on each limiting clamp 54. The locking bolt 55 is slidably connected to the horizontal plate 53, and a locking nut 551 is threadedly installed on each locking bolt 55. Two brackets 2 are slidably installed on the H-shaped frame 1, and the brackets 2 are threadedly connected in a bidirectional manner. Both the screw 3 and the support 2 are equipped with a roller 21 and a soil-breaking gear 22, which are rotatably mounted on a shaft. By rotating the bidirectional screw 3, the spacing between the two supports 2 is adjusted according to the spacing of the agricultural crops, allowing the roller 21 and soil-breaking gear 22 to move along the crops. The H-shaped frame 1 is secured by four feet 11, and a medicine tank 4 is mounted on it. An electric pump 51 is fixedly mounted at the bottom of the medicine tank 4. The electric pump 51 can be started via a battery-powered device and a control switch circuit. The electric pump 51 draws liquid medicine from the medicine tank 4 through a pipe and exits through a discharge pipe 52. The delivery system is housed within a flexible hose 56, which is threaded with multiple nozzles 58 via multiple connectors 57, enabling multiple spray nozzles. Since the spacing between crops can vary, a limiting clamp 54 is fixedly fitted onto each connector 57 of the flexible hose 56. The limiting clamp 54 slides horizontally along a cross plate 53 via a threaded locking bolt 55 and is locked with a locking nut 551. This allows the spacing between the nozzles 58 to be freely adjusted according to the spacing between crops, ensuring precise spraying of the pesticide onto the crops and effectively conserving pesticide usage.
[0027] Reference Figure 1 and Figure 2 A power supply device can also be detachably installed on the H-shaped frame 1. The power supply device is electrically connected to the electric pump 51. The housing of the power supply device can be fixedly installed on the H-shaped frame 1 using threads. The power supply device serves as the power support equipment for the electric pump 51 and is a commonly used storage battery device and control switch circuit. The specific structure and usage method are not described or illustrated in the accompanying drawings, as this is a mature field.
[0028] Reference Figure 1 and Figure 2The H-shaped frame 1 has a sliding groove 12 at each of the four corners of the bottom surface. The upper end of the support 2 is fixed with two sliders, which slide in the sliding groove 12. The distance between the two supports 2 can be adjusted, so that the roller 21 and the soil-breaking gear 22 can be pushed and moved between the crops.
[0029] Reference Figure 1 and Figure 2 The bidirectional screw 3 is provided with two threaded sections 31 with opposite thread directions. The threaded sections 31 are threadedly connected to a bracket 2 respectively. By providing two threaded sections 31 with opposite thread directions, the bidirectional screw 3 can cause the two brackets 2 to move synchronously in opposite directions when the bidirectional screw 3 is rotated.
[0030] Reference Figure 3 and Figure 4 Two T-shaped seats 531 are fixedly provided on the horizontal plate 53. The T-shaped seats 531 are connected to the H-shaped frame 1 by bolts and threads. The horizontal plate 53 has a strip groove 532. The locking bolts 55 are all slidably provided in the strip groove 532. When it is necessary to adjust the position of any nozzle 58, the locking bolt 55 on the corresponding position limit clamp 54 slides along the strip groove 532 of the horizontal plate 53, and then the locking nut 551 is locked, so that the locking nut 551 presses the horizontal plate 53.
[0031] Reference Figure 1 and Figure 3 A ball valve 521 is rotatably installed on the outlet pipe 52. By installing the ball valve 521 on the outlet pipe 52, the liquid in the outlet pipe 52 can be opened and closed.
[0032] Working principle: Two supports 2 are slidably mounted on the H-shaped frame 1, and a double-ended screw 3 is threaded between the supports 2. Each support 2 has a roller 21 and a soil-breaking gear 22 rotatably mounted on its shaft. The spacing between the two supports 2 is adjusted by rotating the double-ended screw 3 according to the spacing of the crops, causing the roller 21 and soil-breaking gear 22 to move along the crops. A medicine box 4 is mounted on the H-shaped frame 1 via four feet 11. An electric pump 51 is fixedly mounted at the bottom of the medicine box 4. The electric pump 51 can be started by a battery-powered device and a control switch circuit. The electric pump 51 is connected to a pipe... The system draws liquid pesticide from the pesticide tank 4 and delivers it through the outlet pipe 52 into a hose 56. The hose 56 is threaded with multiple nozzles 58 via multiple connectors 57, allowing for multiple spray nozzles. Because the spacing between crops can vary, a limiting clamp 54 is fixedly fitted at each connector 57 of the hose 56. The limiting clamp 54 slides horizontally along the cross plate 53 via a threaded locking bolt 55 and is locked with a locking nut 551. This allows the spacing between the nozzles 58 to be freely adjusted according to the spacing between crops, enabling precise spraying of the pesticide onto the crops and effectively saving pesticide usage.
