[0021] The top of the arc rod 809 is equipped with a spring 811, the inside of the spray rack 200 is rotatably connected to a rotating rod 812 that penetrates, the outer side of the rotating rod 812 is fixedly connected to a force plate 813, and the side of the rotating rod 812 is fixedly connected to a blocking block 814. Figure 4From the middle angle of view, the arc rod 809 drives the force plate 813 fixedly connected thereto to rotate clockwise by ninety degrees, and the force plate 813 drives the rotating rod 812 fixedly connected thereto to rotate, so that the rotating rod 812 drives the blocking block 814 fixedly connected thereto to rotate clockwise by ninety degrees, closing the spray rack 200. At this time, the spray rack 200 no longer sprays liquid medicine; as the spray rack 200 continues to rotate, when the force rod 808 is away from the fixed plate 810, the force rod 808 can be reset under the action of the spring 811, and similarly, the blocking block 814 is reset to restore the spray function of the spray rack 200.

The interior of the liquid storage tank 300 is equipped with a stirring assembly 900 for stirring the liquid medicine, and the interior of the moving rod 500 is equipped with an anti-slip friction assembly 1000.

[0022] When in use, the liquid pump 400 is started and the moving rack 100 is pushed by manually operating the moving rod 500. At this time, the directional wheel 600 rotates, driving the bevel gear 1 801 connected thereto to rotate, so that the bevel gear 1 801 drives the bevel gear 2 802 meshing therewith to rotate, and the bevel gear 2 802 drives the gear 1 803 connected thereto to rotate, so that the gear 1 803 drives the gear 2 806 meshing therewith to rotate, and the gear 2 806 drives the pipe joint 805 fixedly connected thereto to rotate, so that the pipe joint 805 drives the spray rack 200 fixedly connected thereto to rotate, and the started liquid pump 400 injects the liquid in the liquid storage tank 300 into the spray rack 200 through the pipe 804 and the pipe joint 805, so that the liquid can be rotated and sprayed out through the spray rack 200; when the spray rack 200 is rotated by Figure 1 In the middle state, the spray head is rotated 90 degrees clockwise or counterclockwise, that is, when the spray head is rotated from the left and right sides to the front and back sides, at this time, the farmland on both sides of the device cannot be sprayed, and the hydraulic tank 807 fixedly connected to the spray rack 200 rotates synchronously with the spray rack 200, and the force-bearing rod 808 slidably connected to the hydraulic tank 807 rotates to the fixed plate 810, and the force-bearing rod 808 is squeezed by the fixed plate 810 and slides into the hydraulic tank 807, so that the pressure in the hydraulic tank 807 increases, driving the arc rod 809 slidably connected to the hydraulic tank 807 to move, so as to prevent the spraying of the farmland on both sides of the device. Figure 4 From the middle angle of view, the arc rod 809 drives the force-bearing plate 813 fixedly connected thereto to rotate ninety degrees clockwise, and the force-bearing plate 813 drives the rotating rod 812 fixedly connected thereto to rotate, so that the rotating rod 812 drives the blocking block 814 fixedly connected thereto to rotate ninety degrees clockwise, closing the spray rack 200. At this time, the spray rack 200 no longer sprays liquid medicine; as the spray rack 200 continues to rotate, when the force-bearing rod 808 moves away from the fixed plate 810, the force-bearing rod 808 can be reset under the action of the spring 811, and similarly, the blocking block 814 is reset to restore the spray function of the spray rack 200. Example

[0023] See also Figure 1-Figure 5 On the basis of the first embodiment, the stirring assembly 900 includes a pneumatic device 901 driven by a servo motor, the top of the gear 803 is connected to the sprocket 902, the outer side of the sprocket 902 is equipped with a chain 903, the top of the movable frame 100 is fixedly connected to a fixed seat 904, the internal rotation of the fixed seat 904 is connected to a penetrating reciprocating screw 905, the outer side of the reciprocating screw 905 is fixedly connected to a sprocket 2 906, and the end of the chain 903 away from the sprocket 1 902 is assembled on the outer side of the sprocket 2 906. Start the pneumatic device 901 driven by the servo motor, so that part of the pneumatic device 901 is in a rotating state. At the same time, when the gear 803 is in a rotating state, it can drive the sprocket 902 connected to it to rotate, and cooperate with the chain 903 assembled on the outside of the sprocket 902 to make the sprocket 906 connected to the sprocket 902 through the chain 903 to rotate, and the sprocket 906 drives the reciprocating screw rod 905 fixedly connected to it to rotate.

[0024] The outer side of the reciprocating screw 905 is connected with a sliding block 907 by setting a thread. The sliding block 907 is located inside the fixed seat 904 and is in a sliding connection with the inner wall of the fixed seat 904. The air pressure device 901 is slidingly connected to the air pumping rod 908 on the side close to the sliding block 907. The air pumping rod 908 is fixedly connected to the sliding block 907. The inside of the air pressure device 901 is respectively equipped with a one-way valve 1 909 and a one-way valve 2 910. When the reciprocating screw 905 is in a rotating state, the sliding block 907 assembled on the reciprocating screw 905 is restricted by the fixed seat 904 that is slidably connected to the sliding block 907, so that the sliding block 907 moves back and forth on the reciprocating screw 905. The sliding block 907 can drive the air pumping rod 908 fixedly connected thereto to move back and forth in the vertical direction. The air pumping rod 908 is slidably connected to the air pressure device 901. Because the air pressure device 901 is respectively equipped with a one-way valve 1 909 and a one-way valve 2 910. The second valve 910 allows the pumping rod 908 to move upward, and then draw the external air to the position between the first and second check valves 909 and 910 through the first check valve 909. When the pumping rod 908 moves downward, the air originally drawn to the inside can be quickly discharged into the liquid storage tank 300 through the second check valve 910. The partial air pressure device 901 in the rotating state in the liquid storage tank 300 can be used to quickly stir the liquid medicine and part of the settled powder in the liquid storage tank 300. This prevents the liquid medicine from settling due to long-term static storage, and improves the use effect of the liquid medicine.

[0025] When in use, on the basis of Example 1, the pneumatic device 901 driven by the servo motor is started, so that part of the pneumatic device 901 is in a rotating state. At the same time, when the gear 1 803 is in a rotating state, it can drive the sprocket 1 902 connected to it to rotate, and cooperate with the chain 903 assembled on the outside of the sprocket 1 902 to make the sprocket 2 906 connected to the sprocket 1 902 through the chain 903 rotate, and the sprocket 2 906 drives the reciprocating screw rod 905 fixedly connected to it to rotate. Because the sliding block 907 assembled on the reciprocating screw rod 905 is restricted by the fixed seat 904 slidably connected to the sliding block 907, the sliding block 907 reciprocates on the reciprocating screw rod 905, and the sliding block 907 It can drive the pumping rod 908 fixedly connected to it to move back and forth in the vertical direction, and the pumping rod 908 is slidably connected to the air pressure device 901. Because the air pressure device 901 is respectively equipped with a one-way valve 909 and a one-way valve 910, when the pumping rod 908 moves upward, the external air can be drawn into the position between the one-way valve 909 and the one-way valve 910 through the one-way valve 909, and when the pumping rod 908 moves downward, the air originally drawn into the interior can be quickly discharged into the liquid storage bin 300 through the one-way valve 910. In conjunction with the partial air pressure device 901 in a rotating state in the liquid storage bin 300, the medicine liquid and part of the settled medicine powder in the liquid storage bin 300 can be quickly stirred. Example

[0026] See also Figure 1-Figure 8 On the basis of the first and second embodiments, the friction assembly 1000 includes a hydraulic chamber 2 1001, a hydraulic chamber 3 1002 is connected to the outer side of the reciprocating screw 905 by transmission, a movable block 1004 is connected to the inside of the hydraulic chamber 3 1002 by setting an elastic expansion plate 1003, and a curved plate 1005 is slidably connected to the side of the hydraulic chamber 3 1002. When the moving frame 100 is in the case of excessively fast movement, the directional wheel 600 rotates rapidly at this time. Similarly, the reciprocating screw 905 is in a fast rotation state, and the reciprocating screw 905 drives the hydraulic chamber 3 1002 connected thereto to rotate rapidly, so that the movable block 1004 in the hydraulic chamber 3 1002 stretches the elastic expansion plate 1003 under the action of centrifugal force, and slides in the hydraulic chamber 3 1002, so that the pressure in the hydraulic chamber 3 1002 increases, driving the curved plate 1005 slidably connected to the hydraulic chamber 3 1002 to move.

[0027] One end of the hydraulic chamber 1001 is slidably connected with a stress rod 1006, which is located at the side of the arc plate 1005 and in contact with the arc plate 1005. The other end of the hydraulic chamber 1001 is slidably connected with a rubber block 1007. When the arc plate 1005 is extended synchronously during the rotation process, the stress rod 1006 is squeezed and driven to move sideways, and the hydraulic chamber 1001 slidably connected to the stress rod 1006 is cooperated, so that the pressure in the hydraulic chamber 1001 is increased, and the rubber block 1007 slidably connected to the hydraulic chamber 1001 is driven to move upward, and the rubber block 1007 then passes through the opening on the moving rod 500 and moves between the palm of the operator and the moving rod 500. The friction between the palm of the operator and the moving rod 500 is increased, the device is prevented from being separated from the operator's hand, and the stability of the device when in use is improved.

[0028] When the moving frame 100 gradually decelerates, the movable block 1004 loses the restriction of the centrifugal force and resets under the action of the elastic expansion plate 1003, so that the force-bearing rod 1006 loses the restriction. At this time, the rubber block 1007 can be squeezed by the palm of the user and move into the moving rod 500, so that the friction assembly 1000 is reset for the next use of the friction assembly 1000.

[0029] During use, on the basis of the first and second embodiments, when the moving frame 100 is in the case of moving too fast, the directional wheel 600 rotates rapidly. Similarly, the reciprocating screw 905 is in a fast rotating state, and the reciprocating screw 905 drives the hydraulic chamber three 1002 connected thereto to rotate rapidly, so that the movable block 1004 in the hydraulic chamber three 1002 stretches the elastic expansion plate 1003 under the action of centrifugal force and slides in the hydraulic chamber three 1002, so that the pressure in the hydraulic chamber three 1002 increases, driving the arc plate 1005 slidably connected to the hydraulic chamber three 1002 to move. At this time, the arc plate 1005 extends synchronously during the rotation process to squeeze the stress-bearing rod two 1006 It also drives the force-bearing rod 1006 to move sideways, and cooperates with the hydraulic warehouse 1001 slidably connected to the force-bearing rod 1006, so that the pressure in the hydraulic warehouse 1001 increases, driving the rubber block 1007 slidably connected to the hydraulic warehouse 1001 to move upward, and the rubber block 1007 then passes through the opening on the moving rod 500 and moves between the operator's palm and the moving rod 500; when the moving frame 100 gradually decelerates, the movable block 1004 loses the restriction of centrifugal force and is reset under the action of the elastic telescopic plate 1003, so that the force-bearing rod 1006 loses the restriction. At this time, the rubber block 1007 can be squeezed by the user's palm and move into the moving rod 500.
