[0004] To achieve the above object, the utility model provides a kind of pesticide spraying is with automatic swinging device of medicine spraying pole, and specific technical solutions are as follows:

[0005] A kind of pesticide spraying is with automatic swinging device of medicine spraying pole, including mounting bracket, one end of the mounting bracket is rotatably installed with pivot, the upper end of the pivot is provided with mounting plate, the mounting plate is provided with turnover plate, the turnover plate can swing left and right on mounting plate, medicine spraying part is installed on the turnover plate, and then the turnover plate can drive medicine spraying part to swing left and right, so that the direction of the liquid sprayed by the nozzle on medicine spraying part changes with the swing of the turnover plate.

[0006] In one of the embodiments, angle adjusting mechanism is provided between the mounting plate and the turnover plate, and the angle adjusting mechanism includes adjusting screw, the adjusting screw is screwed on the mounting plate, and rotating the adjusting screw can make it move up and down on the mounting plate, the top end of the adjusting screw can abut against the bottom surface of the turnover plate, so as to block the turnover plate.

[0007] In one embodiment, the angle adjustment mechanism is provided in two sets, and the two sets of angle adjustment mechanisms are arranged on both sides of the flip plate.

[0008] In one embodiment, a stop block is provided at the top of the adjusting screw, and the stop block can abut against the bottom surface of the flip plate.

[0009] In one embodiment, a locking nut is screwed onto the adjusting screw, which locks the adjusting screw securely to the mounting plate.

[0010] In one embodiment, a limit block is provided at the bottom end of the adjusting screw, and the limit block is located on the lower side of the mounting plate.

[0011] In one embodiment, the mounting plate is provided with support seats on both sides of the upper part, and the flip plate is provided with connecting seats on both sides of the lower part. A connecting shaft is fixed between the two connecting seats, and the connecting shaft passes through the two support seats and is rotatably connected to the support seats.

[0012] In one embodiment, a crank handle is installed on the rear side of the flip plate, which can drive the flip plate to swing left and right.

The connecting nut can fix the connecting bolt to the rotating shaft, thereby realizing the fixed connection between the mounting plate and the rotating shaft.

[0015] The beneficial effects of this embodiment are:

[0016] 1. By installing a mounting plate on the mounting frame, and a flip plate on the mounting plate, the flip plate can swing left and right on the mounting plate. The spraying unit is installed on the flip plate, and the spray bar on the spraying unit can rotate with the flip plate. As a result, the direction of the liquid sprayed from the nozzle on the spray bar changes with the rotation of the flip plate. The direction of the liquid sprayed from the nozzle is no longer perpendicular to the ground, but has a certain angle with the ground. In this way, the liquid sprayed from the nozzle is sprayed outward. The liquid is resisted by the air and will have a reaction force on the spraying unit. This reaction force will have a horizontal thrust on the flip plate and the mounting plate. Driven by the rotating shaft, the flip plate and the mounting plate will drive the spraying unit to swing left and right in the horizontal direction.

The flipping plate can be adjusted by adjusting the flipping angle of the flipping plate, thereby adjusting the angle between the nozzle on the spraying unit and the ground. The smaller the angle, the greater the horizontal reaction force on the spraying unit and the faster the horizontal reverse movement speed of the spraying unit. Conversely, the larger the angle, the slower the horizontal movement speed of the spraying unit. The horizontal movement speed of the spraying unit can be adjusted according to the needs by adjusting the angle adjustment mechanism, which is very convenient and easy to use, and greatly improves the mobility of the device.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0037] The technical solutions provided by the embodiments of this utility model are described below with reference to the accompanying drawings.

[0038] Please see Figures 1-11 An embodiment of this utility model provides an automatic swinging device for pesticide spraying rods, including a mounting frame 100. One end of the mounting frame 100 can be installed on a frame that people carry on their backs when spraying pesticides. The other end of the mounting frame 100 is rotatably mounted with a rotating shaft 110 via a bearing. The outer ring of the bearing and the mounting frame 100 can be fixedly connected by welding or adhesive bonding. The rotating shaft 110 is fixed inside the inner ring of the bearing, so that the rotating shaft 110 can rotate under the drive of the bearing.

[0039] A mounting plate 200 is fixed to the upper end of the rotating shaft 110. A flip plate 300 is provided on the mounting plate 200. The flip plate 300 can swing left and right on the mounting plate 200. A connecting bolt 220 is fixed to the lower side of the mounting plate 200. A through hole (not shown in the figure) is opened at the center of the rotating shaft 110 for the connecting bolt 220 to pass through. The connecting bolt 220 passes through the rotating shaft 110 through the through hole. A connecting nut 230 is screwed to the end of the connecting bolt 220. The connecting nut 230 can fix the connecting bolt 220 to the rotating shaft 110, thereby realizing the fixed connection between the mounting plate 200 and the rotating shaft 110. If the mounting plate 200 and the flip plate 300 are subjected to external force in the horizontal direction, they can drive the rotating shaft 110 to rotate.

[0040] Additionally, support seats 210 are provided on both sides of the upper part of the mounting plate 200, and connecting seats 310 are provided on both sides of the lower part of the flip plate 300. A connecting shaft 320 is fixed between the two connecting seats 310. The connecting shaft 320 passes through the two support seats 210 and is rotatably connected to the support seats 210. Preferably, a crank handle 330 is installed on the rear side of the flip plate 300. By cranking the flip plate 300 with the crank handle 330, the flip plate 300 rotates around the axis of the connecting shaft 320, thereby realizing the left and right swing of the flip plate 300 on the mounting plate 200. As a result, the angle between the spray direction of the nozzle on the spraying part 500 on the flip plate 300 and the ground is changed. The direction of the sprayed liquid is no longer perpendicular to the ground, but has a certain angle with the ground (e.g., the direction of the sprayed liquid is perpendicular to the ground). Figure 10 and Figure 11 As shown), the liquid sprayed from the nozzle is directed outwards. The liquid is resisted by the air, which creates a reaction force on the spraying unit 500. This reaction force provides a horizontal thrust to the flip plate 300 and the mounting plate 200. Driven by the rotating shaft 110, the flip plate 300 and the mounting plate 200 move the spraying unit 500 left and right in the horizontal direction without the need for the operator to manually shake the spraying unit 500. This achieves automatic horizontal movement of the spraying unit 500, greatly saving physical strength and effectively improving work efficiency.

[0041] In addition, since different sprayers spray different liquids at different pressures, some sprayers with lower liquid pressure will result in a smaller reaction force on the spraying part 500 when using this device. This will prevent the spraying part 500 from swaying automatically. The operator will need to apply slight manual assistance to push the spraying part 500 to sway. Of course, the assistance applied by the operator is relatively small, which greatly saves physical strength and effectively improves work efficiency.

[0042] Specifically, a fixing bolt 340 and a positioning pin 350 are provided on the front side of the flip plate 300. The fixing plate of the spraying part 500 is provided with through holes and positioning holes (not shown in the figure) that match the fixing bolt 340 and the positioning pin 350. The positioning pin 350 is inserted into the positioning hole to realize the positioning of the flip plate 300 and the spraying part 500. Then the fixing bolt 340 passes through the through hole and the fixing bolt 340 and the spraying part 500 are fixed together by the nut, thereby realizing the fixed connection between the spraying part 500 and the flip plate 300.

[0043] Preferably, two sets of angle adjustment mechanisms 400 are provided between the mounting plate 200 and the flip plate 300. The two sets of angle adjustment mechanisms 400 are located on both sides of the flip plate 300. Specifically, each angle adjustment mechanism 400 includes an adjusting screw 410, which is screwed onto the mounting plate 200. Rotating the adjusting screw 410 allows it to move up and down on the mounting plate 200. The top end of the adjusting screw 410 abuts against the bottom surface of the flip plate 300, thereby preventing the flip plate 300 from flipping. A stop block 420 is provided at the top end of the adjusting screw 410. The adjusting screw 410 can abut against the bottom surface of the tilting plate 300. The setting of the stop block 420 increases the contact area between the adjusting screw 410 and the tilting plate 300, making it easier to control the tilting angle of the tilting plate 300. A locking nut 430 is screwed onto the adjusting screw 410, which can lock the adjusting screw 410 onto the mounting plate 200. A limit block 440 is set at the bottom end of the adjusting screw 410. The limit block 440 is set on the lower side of the mounting plate 200. The setting of the limit block 440 prevents the adjusting screw 410 from unscrewing off the mounting plate 200, and plays a limiting and protective role.

[0044] An angle adjustment mechanism 400 is provided between the mounting plate 200 and the flip plate 300. The angle adjustment mechanism 400 can adjust the flip angle of the flip plate 300. Specifically, by rotating the adjustment screw 410 counterclockwise, the adjustment screw 410 drives the baffle block 420 to move upward under the drive of the mounting plate 200. This reduces the distance between the baffle block 420 and the flip plate 300, thereby reducing the left and right swing angle of the flip plate 300. As a result, the angle between the nozzle of the spraying part 500 on the flip plate 300 and the ground increases. Conversely, when the adjustment screw 410 moves downward, the angle between the nozzle of the spraying part 500 and the ground decreases.

[0045] See Figure 10 and Figure 11By adjusting the angle between the nozzle on the spraying unit 500 and the ground, the smaller the angle, the greater the reaction force on the spraying unit 500 in the horizontal direction, and the faster the spraying unit 500 moves in the horizontal direction. Conversely, the larger the angle, the slower the spraying unit 500 moves in the horizontal direction. The horizontal movement speed of the spraying unit 500 can be adjusted according to the needs through the angle adjustment mechanism 400. It is very convenient and easy to use, and the mobility of the device is greatly improved.

[0046] The specific operation process is as follows: First, adjust the distance between the adjusting screws 410 on both sides of the mounting plate 200 and the flip plate 300, then adjust the flip angle of the flip plate 300, and push the flip plate 300 by hand through the crank handle 330 so that the flip plate 300 abuts against the adjusting screw 410 on one side. At this time, the flip plate 300 is tilted, and the spraying part 500 on the flip plate 300 forms an angle with the ground.

[0047] Then, the sprayer is turned on and spraying begins. The pesticide is sprayed from the nozzle on the spraying unit 500. Since the nozzle is not perpendicular to the ground but at a certain angle, the pesticide, after being sprayed, will give the spraying unit 500 a backward thrust in the horizontal direction under the action of the air reaction force. The spraying unit 500 then transmits this thrust to the tilting plate 300 and the mounting plate 200 in sequence. Then, the mounting plate 200 drives the rotating shaft 110 to rotate. The rotation of the rotating shaft 110 causes the mounting plate 200 and the tilting plate 300 to rotate around the axis of the rotating shaft 110. Consequently, the spraying unit 500 on the tilting plate 300 also rotates around the axis of the rotating shaft 110, thereby realizing the automatic movement of the spraying unit 500 in the horizontal direction.

[0048] After the spraying unit 500 moves to the predetermined position, the operator manually pushes the flip plate 300 in the opposite direction using the crank handle 330. This causes the flip plate 300 to abut against the adjusting screw 410 on the other side of the mounting plate 200, changing the swing direction of the flip plate 300. Under the reaction force of the pesticide on the spraying unit 500, the spraying unit 500 drives the flip plate 300 and the mounting plate 200 to rotate in the opposite direction around the axis of the rotating shaft 110 until they reach the predetermined position on the other side of the mounting frame 100. Then, the operator manually turns the flip plate 300 back to its original position using the crank handle 330. As a result, the nozzle direction on the spraying unit 500 returns to its original direction, and the spraying unit 500 drives the flip plate 300 and the mounting plate 200 to rotate in the opposite direction around the axis of the rotating shaft 110. This process is repeated cyclically to spray pesticides.
