[0002] Self-propelled boom sprayers are commonly used spraying equipment in modern agriculture, mainly for crop protection operations. They use a spraying system to evenly spray liquid substances such as pesticides and water-soluble fertilizers onto crops to achieve purposes such as pest and disease control, fertilization, and health maintenance. When the device is in use, pesticides are sprayed out by the nozzles on the spray pipe at the front of the sprayer. However, traditional nozzles have some shortcomings in their use.

[0003] Firstly, traditional spray nozzles are typically bolted onto the spray pipe, resulting in a single-direction spray pipe and nozzle. This makes it difficult to flexibly adjust the nozzles to meet the needs of different crops. Some crops require pesticide spraying on their roots and stems, while others require spraying on their leaves. Due to the different spraying heights, a single-direction nozzle cannot meet the needs of multiple crops, affecting the effectiveness of pesticide spraying and crop growth.

[0004] In addition, when the sprayer is not in use, it is usually placed directly on the farmland, where dust and even soil can easily accumulate at the nozzle, causing blockage and affecting its normal use. Utility Model Content

A groove 601 is provided on the inner wall of the top of the connecting block 2. A rotating shaft 65 is rotatably connected through the rear surface of the connecting block 2. A spiral groove 602 is provided on the outer wall of the rotating shaft 65. It only spirals once. A spray pipe 3 is fixedly connected to the rear surface of the rotating shaft 65. A connecting pipe 4 is rotatably connected through the upper surface of the spray pipe 3. The connecting pipe 4 can be connected to one end of an external hose. The other end of the hose can be connected to a sprayer to deliver pesticides. A nozzle 5 is installed on the left surface of the spray pipe 3. Multiple nozzles 5 are provided and are evenly distributed in the back and forth direction on the left surface of the spray pipe 3. A protective component 7 is provided on the upper surface of the spray pipe 3. The protective component 7 can provide protection for the spray pipe 3.

[0033] Reference Figure 1 , Figure 3 , Figure 4 The protective component 7 includes a support block 73, and a rotating rod 72 is rotatably connected to the rear surface of the support block 73. There are two sets of support blocks 73, which are distributed in the front and rear direction to provide support for the front and rear ends of the rotating rod 72. A protective cover 71 is fixedly connected to the upper surface of the rotating rod 72. The protective cover 71 can cover the nozzle 5 and provide protection. A locking block 74 is elastically connected to the inner wall compression spring 75 of the support block 73. The rear end of the locking block 74 is designed to bulge to the left. A slot 701 is opened on the right surface of the rotating rod 72. The rear end protrusion of the locking block 74 fits into the slot 701.

[0034] Reference Figure 1 - Figure 2The motor 61 is located on the inner wall of the rear side of the connecting plate 1. The reciprocating screw 62 passes through and is rotatably connected to the rear surface of the connecting plate 1. The reciprocating screw 62 passes through and is rotatably connected to the front surface of the connecting block 2. The slide rod 64 is slidably connected to the inner wall of the slide groove 601. The slide rod 64 and the slider 63 can only slide along the trajectory of the slide groove 601. The spiral groove 602 is spiral in shape. The slide rod 64 slides on the inner wall of the spiral groove 602. The outer wall of the slide rod 64 contacts the inner wall of the spiral groove 602. When the slide rod 64 moves back and forth, it will squeeze the spiral groove 602, thereby driving the rotating shaft 65 and the spray pipe 3 to rotate, thereby changing the orientation of the nozzle 5.

[0035] Reference Figure 1 , Figure 3 , Figure 4 The protective cover 71 is L-shaped. When the protective cover 71 is rotated 90 degrees to the left, it will cover the nozzle 5 to provide protection. The lower surface of the support block 73 is fixedly connected to the upper surface of the spray pipe 3. The locking block 74 is slidably connected to the rear surface of the support block 73. The front end of the locking block 74 is connected to the front surface of the support block 73. One end of the compression spring 75 is fixedly connected to the right surface of the locking block 74. The other end of the compression spring 75 is fixedly connected to the inner wall on the right side of the support block 73. When the locking block 74 moves to the right, it will squeeze the compression spring 75 to generate a reaction force. The locking block 74 is inserted into the inner wall of the slot 701. When the locking block 74 moves to the right, it will disengage from the slot 701 and release the limit on the rotating rod 72. The slot 701 has two sets with an angle difference of 90 degrees.

[0036] Working principle: When using this device, first install it on the sprayer, then install the external pesticide delivery hose on the connecting pipe 4. Then, adjust the orientation of the nozzle 5 as needed. During adjustment, start the motor 61 to drive the reciprocating screw 62 to rotate, which in turn drives the slider 63 and the sliding rod 64 to move back and forth. When the sliding rod 64 moves back and forth, it will squeeze the spiral groove 602 to drive the rotating shaft 65 to rotate, which in turn drives the spray pipe 3 to rotate and adjust the orientation of the nozzle 5. When the nozzle 5 is adjusted to the appropriate orientation, turn off the motor 61. This operation allows the pesticide to be accurately sprayed onto the leaves or roots of the crop according to its needs, improving the applicability of the device and the utilization rate of the pesticide.

[0037] When crops need to be sprayed on both leaves and roots simultaneously, the motor 61 is started to drive the reciprocating screw 62 to rotate continuously, which in turn drives the slider 63 and the slide bar 64 to move back and forth. The rotating shaft 65, the spray pipe 3 and the nozzle 5 rotate back and forth, thereby expanding the spraying range and spraying pesticides on the leaves and roots of crops at the same time, ensuring spraying efficiency and effectiveness.

[0038] When the device is idle, the locking block 74 and the slot 701 can be moved to the right to disengage and release the limiting force on the rotating rod 72. The rightward movement of the locking block 74 will compress the compression spring 75 to generate a reaction force. After the limiting force on the rotating rod 72 is released, the protective cover 71 can be rotated to drive the rotating rod 72 to rotate. When the protective cover 71 rotates, the locking block 74 can be released. When the locking block 74 and the other slot 701 are aligned, the reaction force of the compression spring 75 will push the locking block 74 and the slot 701 to engage and limit the rotating rod 72, ensuring the stability of the protective cover 71. At this time, the protective cover 71 will cover the nozzle 5, providing protection for the nozzle 5 and preventing the accumulation of dust, mud, animal feces and other debris, which can ensure the stability of the nozzle 5 in subsequent use.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
