Description

Technical Field

[0002] The spray boom is a hollow rod used by sprayers to spray liquid medicine. It can ensure the uniformity of liquid spraying as much as possible and improve the quality and efficiency of liquid spraying. It is usually composed of multiple sections of rods to form an overlapping folding arm structure, which can be unfolded when in use to facilitate the spraying operation of liquid medicine.

[0003] Prior art includes a utility model with publication number CN219719542U, which discloses a folding spray boom mechanism for a crop protection machine. A folding spray boom is connected to both sides of the frame by bolts. A hydraulic pump and a telescopic hydraulic cylinder for controlling the folding second-stage spray boom are installed above the folding first-stage spray boom, and a mechanism for adjusting the angle is installed at the tail end of the telescopic hydraulic cylinder. A folding second-stage spray boom is connected to the tail end of the folding first-stage spray boom, and a clamping mechanism for tightening the spraying rod is installed above the folding second-stage spray boom. Before use, the staff should first fix the angle and position of the folding first-stage spray boom, then open the hydraulic cylinder, extend the telescopic hydraulic cylinder, lift up the folding second-stage spray boom, and extend the folding second-stage spray boom. When the appropriate angle position is reached, the hydraulic pump is turned off to stop the telescopic hydraulic cylinder from extending, so that the folding second-stage spray boom can be fixed at a suitable angle position. The utility model has many folding spray boom sections, which are easy to store and occupy little space.

By setting the clamping plate 22, the spray rod can be clamped to avoid the spray rod from being offset during the spraying process.

[0034] The two clamping plates 22 are glued with rubber pads 23 on the sides close to each other. The second curved plate 18 is fixedly connected to the side close to the first curved plate 17 with a sliding rod 20. The sliding rod 20 is slidably connected to the inner wall of the first curved plate 17. The other end of the sliding rod 20 is fixedly connected to a baffle 21. By setting the sliding rod 20, the second curved plate 18 can be installed, and at the same time, the second curved plate 18 can be moved. By setting the baffle 21, the stable connection between the second curved plate 18 and the first curved plate 17 can be ensured. The inner wall of the second curved plate 18 is threadedly inserted with a second screw 19, and one end of the second screw 19 is rotatably connected to the first curved plate 17. The side of the first display plate 3 is fixedly connected with the first fixed plate 8, and the side of the rotating plate 7 is fixedly connected with the mounting plate 9.

By setting the second screw 19, the second arc plate 18 can be controlled to move, and by setting the first screw 10, the first pad 11 can be controlled to move closer to or farther from the first fixed plate 8. By setting the first pad 11, the rotation of the rotating plate 7 can be restricted. The upper surface of the storage box 1 is fixedly connected with a "U"-shaped plate 24, and the inner wall of the "U"-shaped plate 24 is slidably connected with a pull rod 25. The end of the pull rod 25 away from the rotating rod 2 is fixedly connected with a pull plate 26. The surface of the pull rod 25 is sleeved with a spring 27, and the two ends of the spring 27 are respectively fixedly connected to the "U"-shaped plate 24 and the pull plate 26. The end of the pull rod 25 close to the mounting plate 9 is fixedly connected with a second pad 28. By setting the "U"-shaped plate 24, the pull rod 25 and the second pad 28 can be installed. By setting the spring 27, the stable connection between the pull rod 25 and the "U"-shaped plate 24 can be ensured. By setting the second pad 28, the rotation of the rotating rod 2 can be restricted.

[0035] Working principle: Before using the spray rod to spray the liquid, first, the spray rod is passed through the first pipe hole 29 into the storage box 1, and then the spray rod is moved through the fixed rod 6 and the first rotating roller 4, and then the spray rod is installed on the side of the second display board 12 close to the top plate 14 through the second pipe hole 30, and then the spray rod is moved through the two second rotating rollers 13 close to the clamping plate 22, and then the second display board 12 is rotated to drive the rotating plate 7 to rotate on the surface of the fixed rod 6, and at the same time, the first display board 3 is rotated to make the rotating rod 2 rotate on the inner wall of the storage box 1, so that the spray rod is unfolded with a folding structure. By setting the limit plate 5, the position of the spray rod can be limited. By setting the storage box 1, the first rotating plate 7, the second rotating plate 7 and the top plate 14, the weight of the folding structure for the spray rod is lighter, so that the load strength of the connecting shaft can be reduced as much as possible when the folding structure for the spray rod is unfolded, so that the service life of the folding structure for the spray rod can be guaranteed as much as possible. At the same time, the unilateral unfolding method is adopted to reduce the width of the folding structure for the spray rod as much as possible, and the passability of the spray rod is guaranteed as much as possible, which facilitates the use of the spray rod for spraying liquid.

[0036] After the spray rod is installed, the second screw rod 19 is rotated to rotate on the surface of the first curved plate 17, and the second curved plate 18 is controlled to move close to the first curved plate 17. At the same time, the sliding rod 20 slides on the inner wall of the first curved plate 17. At this time, the two clamping plates 22 and the rubber pad 23 clamp and fix the spray rod to limit the position of the spray rod. By setting the baffle 21, the moving distance of the second curved plate 18 can be limited. Then, the pull plate 26 is pulled to drive the pull rod 25 and the second pad 28 to move away from the storage box 1, thereby releasing the restriction on the rotating rod 2. The first display plate 3 is rotated to unfold it, and the pull plate 26 is released. Under the action of the elastic force of the spring 27, the pull rod 25 slides on the inner wall of the "U"-shaped plate 24, so that the pull rod 25 and the second pad 28 move close to the rotating rod 2, thereby limiting the position of the rotating rod 2. The control is performed, and then the first screw 10 is rotated to rotate on the inner wall of the mounting plate 9, the first pad 11 is controlled to move close to the first fixed plate 8, and the rotation of the second display panel 12 is restricted. By setting the first rectangular plate 15 and the second rectangular plate 16, the first arc plate 17 can be installed, and the movement trajectory of the clamping plate 22 can be restricted. By setting the clamping plate 22 and the rubber pad 23, the position of the spray rod can be restricted during the spraying of the liquid medicine by the spray rod, thereby avoiding the deflection of the spray rod during the spraying of the liquid medicine as much as possible. By setting the first screw 10 and the first pad 11 and the pull rod 25 and the second pad 28, the position of the display panel can be restricted after the folding structure for the spray rod is unfolded, thereby ensuring the normal progress of the spraying operation as much as possible.
