[0021] This utility model provides an agricultural spraying device, including a frame 101, a liquid storage tank 102, a conveying assembly 103, and a spraying assembly 104. The spraying assembly 104 includes a spraying pipe 105, a nozzle 106, a sleeve 107, a sealing sleeve 108, a push plate 109, a locking component 110, and a reset component 111. The locking component 110 includes a spring 112 and a locking element 113. The sleeve 107 has a first locking groove 114 and a second locking groove 115. The reset component 111 includes a mounting plate 116. The conveying assembly 103 includes a conveying pump 118 and a conveying pipe 119. By pushing the push plate 109 to move, the sealing sleeve 108 is moved, so that the spray hole 121 on the sealing sleeve 108 is offset from or coincides with the through hole 120, thereby sealing or starting the spray head 106 and achieving the purpose of adjusting the spray range. It can be understood that the above solution can be used for precise adjustment of the spray range of the medicine, and can also be used to make the sealing sleeve 108 automatically reset.

[0022] In this specific embodiment, the storage tank 102 is mounted on the frame 101, and the conveying assembly 103 is disposed inside the storage tank 102. The frame 101 is provided with casters at the bottom to facilitate the movement of the device by the operator. The storage tank 102 contains a mixture of pesticide and water. The storage tank 102 is also provided with a stirring structure (not shown in the figure) to stir and mix the pesticide and water. The principle of the stirring structure is existing technology and will not be described in detail here. The conveying assembly 103 is used to deliver the pesticide solution to the spray pipe 105.

[0023] The spray pipe 105 is fixedly connected to the liquid storage tank 102 and communicates with the conveying assembly 103. The nozzle 106 is fixedly connected to the spray pipe 105 and communicates with it. The sleeve 107 is fixedly connected to the liquid storage tank 102 and is fitted onto the spray pipe 105. The sealing sleeve 108 is rotatably connected to the sleeve 107 and is fitted onto it. The push plate 109 is fixedly connected to the sealing sleeve 108 and is located on one side of the sealing sleeve 108. The locking member 110 is disposed on the push plate 109, and the reset member 111 is disposed on the sleeve 107. Two components 104 are provided, located on opposite sides of the liquid storage tank 102. A spray pipe 105 is provided with multiple nozzles 106, which are evenly distributed on the spray pipe 105. A sleeve 107 is provided with multiple sealing sleeves 108 and a push plate 109. The position of the sealing sleeves 108 corresponds one-to-one with the position of the nozzles 106. The sleeve 107 is provided with several through holes 120 corresponding to the multiple nozzles 106. The pesticide sprayed by the nozzles 106 can be sprayed onto the crops through the through holes 120. The sealing sleeves 108 are provided with spray holes 121 corresponding to the nozzles 106.

[0024] In use, the liquid medicine inside the storage tank 102 is transported to the spray pipe 105 through the conveying component 103, and the liquid medicine is sprayed out through the multiple nozzles 106 on the spray pipe 105. The liquid medicine is sprayed out through the through hole 120 and the spray hole 121 on the sleeve 107, thereby spraying the crops. At the same time, the operator pushes the frame 101 to move, thereby moving the storage tank 102 and the spray pipe 105, so that the spray pipe 105 can spray the crops in the field. When it is necessary to adjust the spraying range, the push plate 109 is pushed to move according to the position of the crops, so that the push plate 109 drives the sealing sleeve 108 to rotate, thereby disengaging the spray hole 121 from the through hole 120. Then, the locking component 110 locks the sealing sleeve 108, at which time the corresponding nozzle 106 is sealed, and the spraying of liquid medicine stops at that position, thereby achieving precise control of spraying specific areas.

[0025] Secondly, the locking member 113 is slidably connected to the push plate 109 and is disposed on the push plate 109; the two ends of the spring 112 are respectively connected to the push plate 109 and the locking member 113, and the spring 112 is sleeved on the locking member 113.

[0026] Meanwhile, the first locking groove 114 is provided on one side of the sleeve 107; the second locking groove 115 is provided on one side of the sleeve 107, and both the first locking groove 114 and the second locking groove 115 cooperate with the locking member 113.

[0027] The first locking groove 114 and the second locking groove 115 correspond to the open position and the sealed position of the sealing sleeve 108, respectively. The top of the locking member 113 is also equipped with a pull ring. The locking member 113 is driven to move downward by the spring 112, so that the locking member 113 can extend into the first locking groove 114, thereby locking the sealing sleeve 108 in the open position. When it is necessary to adjust the spray range, the locking member 113 is pulled upward, so that the locking member 113 moves out of the first locking groove 114. At this time, the push plate 109 is rotated to move the locking member 113 to the second locking groove 115. Then, the pulling of the locking member 113 is stopped, and the locking member 113 can extend into the second locking groove 115 under the action of the spring 112, thereby locking the sealing sleeve 108 in the sealed position.

[0028] In addition, the mounting plate 116 is fixedly connected to the sleeve 107 and is disposed on the sleeve 107; the two ends of the spring plate 117 are respectively connected to the mounting plate 116 and the push plate 109, and the spring plate 117 is located between the mounting plate 116 and the push plate 109; when the push plate 109 rotates, it squeezes the spring plate 117, causing the spring plate 117 to accumulate elastic potential energy. In this way, when it is necessary to increase the spraying range, the locking member 113 is pulled to move it out of the second locking groove 115. At this time, the push plate 109 can automatically reset under the action of the spring plate 117, thereby driving the sealing sleeve 108 to rotate to the open position, so as to facilitate rotating the sealing sleeve 108 to the open state.

[0029] Finally, the delivery pump 118 is connected to the storage tank 102 and is located inside the storage tank 102; both ends of the delivery pipe 119 are connected to the delivery pump 118 and the spray pipe 105 respectively, and the delivery pipe 119 is installed on the delivery pump 118; there are two delivery pipes 119, which are respectively connected to two spray pipes 105. The delivery pump 118 delivers the medicine inside the storage tank 102 to the delivery pipe 119, and then the delivery pipe 119 delivers the medicine to the spray pipe 105, thereby achieving the purpose of delivering medicine to the spray pipe 105.

[0030] When using the agricultural spraying equipment of this utility model, when it is necessary to adjust the spraying range, pull the locking member 113 out of the first locking groove 114. At this time, the push plate 109 can rotate, and by pushing the push plate 109, the sealing sleeve 108 is rotated, so that the spraying hole 121 is misaligned with the through hole 120. At this time, the nozzle 106 is sealed, thereby stopping the spraying of pesticide at this position. When the locking member 113 rotates to the second locking groove 115, the locking member 113 extends into the second locking groove 115 under the action of the spring 112, thereby fixing the spraying range. The sealing sleeve 108 is locked in place. When it is necessary to spray the pesticide at this position again, the locking member 113 is pulled again to move it out of the second locking groove 115. At this time, the push plate 109 and the sealing sleeve 108 can be reset under the action of the spring plate 117, so that the spray hole 121 and the through hole 120 are re-aligned. At this time, the nozzle 106 at the corresponding position can spray the pesticide. This not only avoids the waste of pesticide in non-target areas, but also improves the efficiency and accuracy of spraying. It is especially suitable for situations where crops are unevenly distributed in the field or where it is necessary to focus on the prevention and control of specific diseases.

[0031] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
