DETAILED DESCRIPTION

[0030] It is easy to understand that, according to the technical scheme of the present application, those skilled in the art can propose various structural modes and implementation modes that can be replaced with each other without changing the essential spirit of the present application. Therefore, the following detailed description and the accompanying drawings are only exemplary descriptions of the technical scheme of the present application, and should not be regarded as the whole or as a limitation or restriction on the technical scheme of the present application.

[0031] A precise spraying liquid manure field equipment, as shown in Figure 1 The storage tank 1 is used to store liquid manure, the bottom end of the storage tank 1 is provided with a base 2 for overall installation, for example, installation on an agricultural vehicle to facilitate overall movement, the inside of the storage tank 1 is provided with a water pump 14, the end of the base 2 is rotatably connected with two support assemblies 3, the side of each support assembly 3 is provided with a plurality of spraying assemblies 4, the top end of the support assembly 3 is provided with a rotary joint 7, the spraying assembly 4 is connected to the rotary joint 7 through the support assembly 3, the rotary joint 7 includes a joint body 71, a ball plug 72, an inlet 73, an outlet 74 and a communication pipe 75, one end of the communication pipe 75 communicates with the water pump 14, the other end of the communication pipe 75 communicates with the joint body 71, the ball plug 72 is rotatably connected inside the joint body 71, the surface of the ball plug 72 is provided with the inlet 73 with a triangular cross section, the bottom end of the ball plug 72 is provided with the outlet 74, the inlet 73 communicates with the outlet 74, the bottom end of the joint body 71 is rotatably connected with the support assembly 3, the ball plug 72 is fixed with the support assembly 3, the inside of the base 2 is provided with a motor one 21, as Figure 2The output end of the motor 21 is connected to the support assembly 3; the side of the support assembly 3 is provided with a measuring assembly 6, the measuring assembly 6 and the motor 21 are connected to a controller; the measuring assembly 6 measures the width of the area to be sprayed, and the controller starts the motor 21 according to the width of the area to be sprayed, thereby changing the spraying area of the spraying assembly 4; the motor 21 can drive the ball plug 72 to rotate when started, so as to change the inlet flow of the inlet 73. The measuring assembly 6 includes a laser radar (LiDAR) or a camera and computer vision, for example. The laser radar (LiDAR) calculates the distance by emitting a laser beam and measuring the time of its reflection. It can provide high-precision three-dimensional images, and has high precision and is suitable for long-distance detection. The camera and computer vision capture images through the camera and analyze the spraying width in the image through computer vision algorithms; combined with deep learning technology, the edge of the farmland can be more accurately identified.

[0032] In use, the two support assemblies 3 are in a fully open state, which is the maximum spraying width, and the ball plug 72 is aligned with the communication pipe 75 to achieve the maximum spraying flow. The spraying width in the measured area is measured by the measuring assembly 6. If one side is an edge area, the edge area is irregular, and the spraying area needs to be reduced. The measuring assembly 6 measures and determines that the width of the area to be sprayed on one side needs to be reduced. When the area is about to be reached, the motor 21 is started. When the motor 21 is started, the support assembly 3 on that side is rotated to reduce the spraying area. The ball plug 72 is synchronously rotated when the support assembly 3 is rotated. The inlet 73 is reduced when the ball plug 72 is rotated, and the spraying flow is reduced to adapt to the reduction of the spraying area.

The spraying area of the spraying assembly 4 can be changed when the spraying assembly 4 is rotated, so as to adapt to the measured width. When the spraying area of the spraying assembly 4 is changed, the ball plug 72 is rotated, so as to control the fertilizer flow, avoid the increase of the fertilizer application amount after the reduction of the spraying area, and ensure the uniformity of the fertilizer application.

The blocking plate 44 is used to block the spray head 43 when not fertilizing, so as to avoid the liquid fertilizer remaining in the spraying pipe 42 and the spray head 43 from flowing out, affecting the environment.

[0036] In order to adjust whether the blocking plate 44 is used according to the needs, the side of the baffle 41 is rotatably connected with an adjusting assembly 5, which is used to adjust the angle of the baffle 41 rotating around the spraying pipe 42; the adjusting assembly 5 comprises a rotating handle 51, movable rods 52, a screw rod 53, a top plate 54, a cross rod 55 and a limiting plate 56; as shown in Figure 4 , the side of the connecting rod 34 is fixed with the limiting plate 56, and the limiting plate 56 is inserted with the movable rods 52; the bottom end of the movable rod 52 is rotatably connected with the baffle 41; the top end of each movable rod 52 is connected through the cross rod 55, and the two ends of the cross rod 55 are connected to the top plate 54; the two ends of the limiting plate 56 are threadedly connected with the screw rod 53, and the bottom end of the screw rod 53 is provided with the rotating handle 51; the top end of the screw rod 53 is matched with the top plate 54; when the spray head 43 needs to be used, the screw rod 53 is rotated through the rotating handle 51 to make the movable rod 52 drive the baffle to rotate, at the same time, the blocking plate 44 presses the spraying pipe 42 to rotate, so as to adapt to the rising of the movable rod 52, at this time, the blocking plate 44 can be rotated away from the spray head 43, so as to use the spray head 43 for spraying.

When liquid manure is input into the input pipe 11, the rotating filter assembly 8 filters the manure.

[0040] The filter component 8 of the present invention can filter liquid manure when it is input. During filtration, the filter component 8 can rotate to increase the stirring force of the manure and avoid local blockage of the filter component 8, which would cause poor manure discharge.
