[0006] Compared with the existing status in the art, the present invention is provided with a double rocker mechanism composed of rocker I, rocker II, U-shaped frame and mounting frame, so that the medicine dispensing box can move up and down with the swing of rocker I and rocker II, so as to realize the conversion of the medicine dispensing box between the two positions of "medicine dispensing state" and "medicine spraying and transportation state", thereby completely solving the problems of inconvenience in medicine dispensing operation and scratches during medicine spraying and transportation; because a locking plate with a guide groove and a locking groove and a handle with a protrusion are provided, and the medicine dispensing box is in the "medicine dispensing state" and "medicine spraying and transportation state", the medicine dispensing box can be easily moved up and down with the swing of rocker I and rocker II, so as to realize the conversion of the medicine dispensing box between the two positions of "medicine dispensing state" and "medicine spraying and transportation state". When the sprayer is in the "spraying or transporting" state, the protrusions on the handle are aligned with the locking groove and the guide groove on the locking plate respectively. Therefore, after the protrusions are inserted into the locking groove or the guide groove, the position of the medicine dispensing box is ensured to remain unchanged, which greatly improves the operating safety and reliability of the sprayer in the "dispensing" and "spraying or transporting" states; since the distances between the hinge points at both ends of the rocker I and the rocker II are equal and parallel to each other, and the rocker I, the rocker II, the U-shaped frame and the mounting frame form a double rocker with the rocker I and the rocker II parallel and equal in length, The medicine box body always keeps the vertical state unchanged when the medicine dispensing box moves up and down, so that the medicine dispensing box can be switched freely between the two positions of "medicine dispensing state" and "medicine spraying and transportation state"; due to the long return spring, the downward movement speed of the medicine dispensing box is slowed down during the downward movement due to the elongation of the long return spring, and the upward movement speed of the medicine dispensing box is also slowed down during the upward movement due to the gradual reset of the long return spring, so that the medicine dispensing box can be effectively prevented from approaching the "medicine dispensing state" or "medicine spraying and transportation state". The device is prevented from being damaged by a collision due to excessive speed when the handle is moved to the position; due to the short return spring, the arm can release the handle after the handle is moved and the protrusion exits the guide groove or locking groove on the locking disk. Under the tension of the short return spring, the protrusion is always pressed against the arc surface of the locking disk. When the protrusion is aligned with the locking groove or guide groove on the locking disk, the protrusion is stuck in the locking groove, ensuring that the locking disk and the retractable assembly remain stationary, thereby reliably locking the medicine dispensing box in the "medicine dispensing state" or "medicine spraying and transportation state".

[0009] exist Figure 1-Figure 11In the embodiment shown, the mounting frame 1 is in the shape of a U-shaped groove and is mounted on the frame of the sprayer through the side wall of the U-shaped groove; a mounting plate 11 extends from each end of the bottom of the U-shaped groove of the mounting frame 1, the two mounting plates 11 are parallel to each other, perpendicular to the side wall of the U-shaped groove of the mounting frame 1, and form an acute angle with the bottom surface of the U-shaped groove of the mounting frame 1, and a handle lug 12 is provided on the plate surface of the mounting plate 11. The locking plate 211 of the locking assembly 21 of the storage frame 2 is in the shape of a fan, and the fan center of the locking plate 211 is hinged between the two mounting plates 11 of the mounting frame 1 through a pin 212; a guide groove 2111 and a locking groove 2112 are provided on the arc surface of the locking plate 211, and the length directions of the guide groove 2111 and the locking groove 2112 are along the radial direction of the locking plate 211, so as to guide the storage assembly 23 and lock the handle 213. A protrusion 2131 protrudes inward from the "J"-shaped head end of the handle 213 in a "J" shape, and is hinged to the handle lug 12 of the mounting frame 1 through the "J"-shaped head end of the handle 213; when the sprayer is in the spraying or transportation state, the protrusion 2131 at the "J"-shaped head end is clamped in the guide groove 2111 of the locking plate 211, and when the sprayer is in the medicine dispensing state, the protrusion 2131 at the "J"-shaped head end is clamped in the locking groove 2112 of the locking plate 211; a short return spring 214 is hung between the "J"-shaped head end of the handle 213 and the pin shaft 212 to ensure that when the protrusion 2131 at the "J"-shaped head end is aligned with the guide groove 2111 or the locking groove 2112, the protrusion 2131 is clamped in the guide groove 2111 or the locking groove 2112 and will not fall out. A ring-shaped box protection rod 222 is installed on one side of the medicine box base 221 of the medicine box rack 22, and the ring plane of the box protection rod 222 is perpendicular to the board surface of the medicine box base 221; a U-shaped frame 223 in the shape of a U-shaped groove is installed on the side edge of the medicine box base 221 parallel to the ring plane of the box protection rod 222, and the U-shaped frame 223 extends with a retractable lug 2231 in the direction away from the medicine box base 221. One end of the rocker I231 of the retractable assembly 23 is hinged between the two mounting plates 11 of the mounting frame 1, and the other end is hinged in the U-shaped groove of the U-shaped frame 223 of the medicine box frame 22; one end of the rocker II232 which is parallel and equal to the rocker I231 is hinged on the plate surface of the mounting plate 11 of the mounting frame 1 with a handle lug 12, and the other end is hinged on the retractable lug 2231 of the U-shaped frame 223 of the medicine box frame 22; therefore, the rocker I231, the rocker II232, the U-shaped frame 223 and the mounting frame 1 constitute a double rocker mechanism in which the rocker I231 and the rocker II232 are parallel and equal in length.One end of the rocker I 231 hinged on the mounting plate 11 of the mounting frame 1 extends outward from the medicine box frame 22 with a guide pin 233, and the guide pin 233 is clamped in the guide groove 2111 of the locking plate 21 of the locking assembly 21; therefore, when the rocker I 231 swings around the hinge point on the mounting plate 11 of the mounting frame 1, the guide pin 233 slides in the guide groove 2111 of the locking plate 211 and drives the locking plate 211 to rotate around the hinge point on the mounting plate 11 of the mounting frame 1. One end of the long return spring 3 is hung on the middle of the rocker I 231 of the retractable assembly 23, and the other end is hung on the mounting frame 1, so that after the dispensing work is completed, it can help the dispensing box 5 to return to the transportation state; the control valve group 4 is installed on the box protection rod 222 of the medicine box frame 22 of the retractable frame 2, so as to provide the sprayer with a suitable proportion of liquid medicine as needed. The medicine box body 51 of the medicine dispensing box 5 is in a funnel shape. The medicine box body 51 is installed on the medicine box seat plate 221 of the medicine box rack 22 of the storage rack 2. The funnel-shaped bottom of the medicine box body 51 is equipped with a ball valve assembly 52.

[0010] Its working principle is as follows: before the sprayer implements the medicine dispensing operation, the handle of the locking assembly of the storage rack is moved, and the short return spring between the handle and the pin of the locking assembly of the storage rack is stretched, and the convex block of the handle is withdrawn from the guide groove of the locking plate. The medicine dispensing box stretches the long return spring between the middle part of the rocker I of the storage rack and the mounting frame under the action of gravity, and then moves downward, and the rocker I and rocker II in the double rocker mechanism composed of the U-shaped frame, the rocker I and rocker II of the storage rack and the mounting frame are driven by the U-shaped frame of the medicine box rack of the storage rack to swing around the hinge points on the rocker I and rocker II and the mounting plate of the mounting frame. With the swing of rocker I and rocker II and the downward movement of the medicine dispensing box, the long return spring is stretched longer and longer, and the pulling force is also increasing, so the downward movement speed of the medicine dispensing box is getting slower and slower.

[0011] At the same time, since the arm releases the handle after moving it, the handle is always pressed against the arc surface of the locking plate under the action of the tension of the short return spring; when the rocker I swings around the hinge point between the rocker I and the mounting plate of the mounting frame, the guide pin at the end of the rocker I slides in the guide groove of the locking plate and drives the locking plate to rotate around the hinge point with the mounting plate of the mounting frame. When the locking plate rotates until the locking groove on the locking plate is aligned with the lug at the head end of the handle, the lug is stuck in the locking groove under the action of the tension of the short return spring, the locking plate stops rotating, the rocker I and the rocker II stop swinging, the medicine dispensing box stops moving down, and is locked in the "medicine dispensing state" position and remains motionless. After the dispensing operation is completed as required, the liquid medicine is sucked into the main medicine box.

[0012] After all the liquid medicine is sucked into the main medicine box, move the handle again, stretch the short return spring, and then withdraw the handle's protrusion from the locking groove of the locking plate, gently push the medicine box upward, and the pulling force of the long return spring makes the medicine box move upward, and drives the rocker I and rocker II in the double rocker mechanism to swing around the hinge point respectively through the U-shaped frame. As the rocker I and rocker II swing and the medicine box moves upward, the long return spring is stretched less and less, and the pulling force is getting smaller and smaller, so the upward movement speed of the medicine box is getting slower and slower.

[0013] At the same time, since the arm releases the handle after moving it, the handle is always pressed against the arc surface of the locking plate under the action of the tension of the short return spring; when the rocker I swings around the hinge point, the guide pin drives the locking plate to rotate around the hinge point. When the locking plate rotates until the guide groove on the locking plate is aligned with the lug, the handle is clamped into the guide groove under the action of the tension of the short return spring, the locking plate stops rotating, the rocker I and rocker II stop swinging, the medicine dispensing box stops moving up, and is locked in the position of "spraying and transporting state" and remains motionless. Then, the spraying operation can begin. After completing all the spraying tasks, return to the warehouse while maintaining the "spraying and transporting state".
