[0047] Example 2

[0048] Reference Figures 1 to 3 、 Figure 5 and Figures 9 to 13 , which is the second embodiment of the present invention, and is based on the previous embodiment.

[0049] Specifically, the medicine storage unit 202 includes a support column 202a, a medicine box 202b and a medicine outlet pipe 202c. The support column 202a is arranged on the top of the medicine dispensing box 201b, the medicine box 202b is located on the top of the support column 202a, and the medicine outlet pipe 202c is arranged at the bottom of the medicine box 202b.

[0050] The support column 202a is fixed to the top of the medicine dispensing box 201b and is used to fix and support the medicine box 202b. The medicine box 202b is used to store the medicine concentrate. The medicine outlet pipe 202c is fixed to the bottom of the medicine box 202b and is used to transport the medicine concentrate in the medicine box 202b. A vent is provided on the top of the medicine box 202b to facilitate the medicine concentrate in the medicine box 202b to flow into the medicine outlet pipe 202c. When the medicine in the medicine box 202b is used up, the sealing cover of the medicine box 202b is opened and the medicine concentrate is added to the medicine box 202b.

[0051] Specifically, the medicine storage member 202 further includes a sleeve 202d, a first spring 202e and a first piston 202f. The sleeve 202d is arranged at the end of the medicine outlet tube 202c, the first spring 202e is located on the inner wall of the sleeve 202d, and the first piston 202f is arranged in the sleeve 202d.

[0052] The sleeve 202d is connected to the medicine outlet pipe 202c, and the two ends of the first spring 202e are respectively fixed to the inner wall of the sleeve 202d and one side of the first piston 202f. The first spring 202e is in a compressed state, and the first piston 202f slides in the sleeve 202d. The first piston 202f can block the communicating hole between the sleeve 202d and the medicine outlet pipe 202c, so that the medicine cannot enter the sleeve 202d from the medicine outlet pipe 202c. When the first piston 202f is away from the communicating hole, the medicine enters the sleeve 202d from the medicine outlet pipe 202c. The multiple through holes opened on the surface of the first piston 202f allow the medicine to flow from one side of the first piston 202f to the other side.

[0053] Specifically, the medicine storage component 202 also includes a support tube 202g, a second spring 202h, a second piston 202i, a third spring 202j, an extrusion column 202k and a nozzle 202l. The support tube 202g is arranged at the top of the medicine dispensing box 201b, the second spring 202h is located on the inner wall of the support tube 202g, the second piston 202i is arranged at the end of the second spring 202h, the third spring 202j is located on the inner wall of the support tube 202g, the extrusion column 202k is arranged in the support tube 202g, and the nozzle 202l is located on one side of the support tube 202g.

[0054] The support tube 202g is fixed to the top of the medicine dispensing box 201b, and the support tube 202g is connected to the sleeve 202d. The two ends of the second spring 202h are respectively fixed to the inner wall of the support tube 202g and one side of the second piston 202i. The second spring 202h is in a compressed state. The second piston 202i slides on the end of the second spring 202h. A plurality of through holes are opened on the surface of the second piston 202i, which are used to allow the medicine liquid to flow from one side of the second piston 202i to the other side. When the second piston 202i squeezes the inner wall of the flow channel inside the support tube 202g, the flow of the medicine liquid in the support tube 202g can be blocked. The two ends of the third spring 202j are respectively fixed to the inner wall of the support tube 202g and one side of the extrusion column 202k. The extrusion column 202k slides in the support tube 202g, and the nozzle 202l is connected to the support tube 202g.

[0055] When the squeezing column 202k slides in the support tube 202g, squeezing the third spring 202j and squeezing the liquid in the support tube 202g at the same time, the liquid pressure in the support tube 202g increases, so that the liquid presses the first piston 202f only on one side of the communicating hole between the sleeve 202d and the medicine outlet pipe 202c, so that the medicine cannot enter the sleeve 202d from the support tube 202g. The liquid in the support tube 202g squeezes the second piston 202i, so that the second piston 202i is away from the inner wall of the flow channel of the support tube 202g. At this time, the flow of the medicine in the support tube 202g will not be blocked, and the medicine can flow from one side of the second piston 202i to the other side, and then flow into the nozzle 202l, and enter the dispensing box 201b from the nozzle 202l, thereby completing the addition of the medicine stock solution. At this time, the squeezing of the squeezing column 202k is stopped, and under the action of the reset elastic force of the third spring 202j, the medicine is released. The second piston 202i is reset and moves under the action of the return elastic force of the second spring 202h, and squeezes the inner wall of the flow channel of the support tube 202g again, so that the flow of the liquid in the support tube 202g is blocked. The movement of the squeezing column 202k causes the pressure of the liquid in the support tube 202g to form a negative pressure, causing the liquid in the medicine box 202b to squeeze the first piston 202f through the medicine outlet pipe 202c, so that the first piston 202f compresses the first spring 202e, and the medicine stock liquid enters the sleeve 202d from the medicine outlet pipe 202c, and then enters the support tube 202g from the sleeve 202d, replenishing the medicine stock liquid in the support tube 202g. In this way, the medicine stock liquid in the medicine box 202b can be continuously transported to the dispensing box 201b through the repeated movement of the squeezing column 202k in the support tube 202g.

The support tube 202g is repeatedly moved in the support tube 202g, thereby continuously delivering the raw medicine liquid in the medicine box 202b to the dispensing box 201b. The position of the protrusion 204h can be adjusted by rotating the adjusting bolt 204g, thereby changing the amplitude of movement of the support tube 202g when the protrusion 204h squeezes the support tube 202g, thereby changing the speed at which the raw medicine liquid in the medicine box 202b is delivered to the dispensing box 201b, thereby changing the ratio of the raw medicine liquid to water, thereby changing the concentration of the configured medicine.

[0063] Specifically, the adjusting member 205 includes a support rod 205a, a limit bar 205b, a slide column 205c, a positioning hook 205d, a fourth spring 205e, a fixing block 205f, a positioning column 205g, a driving column 205h, a collar 205i, a fifth spring 205j, a slide rod 205k, a paddle 205l, a connecting barrel 205m, a floating block 205n, a first driving block 205o and a second driving block 205p.

[0064] The support rod 205a is fixed to the top of the medicine dispensing box 201b. There are two limit bars 205b, both fixed to one side of the support rod 205a. There are two slide columns 205c, which slide on the surface of the limit bars 205b respectively, and the slide column 205c is clamped on one side of the support rod 205a, thereby limiting the position of the slide column 205c. The positioning hook 205d is fixed to one side of the slide column 205c, which is used to limit the positioning column 205g, thereby limiting the handle of the butterfly valve 203e. The two ends of the fourth spring 205e are respectively fixed to the inner wall of the sliding column 205c and the side of the fixed block 205f, the fixed block 205f is fixed to the side of the support rod 205a, the positioning column 205g is fixed to the end of the handle of the butterfly valve 203e, the driving column 205h is fixed to the handle of the butterfly valve 203e, the collar 205i is rotatably connected to the surface of the driving column 205h, the two ends of the fifth spring 205j are respectively fixed to one side of the collar 205i and the surface of the sliding rod 205k, and the sliding rod 205k slides on the medicine dispensing box In the medicine dispensing box 201b, there are two picks 205l, both of which are fixed to one side of the slide bar 205k, and the two picks 205l are arranged opposite to each other. The connecting barrel 205m is fixed in the medicine dispensing box 201b. A through hole is opened at the bottom of the connecting barrel 205m so that the liquid level in the connecting barrel 205m is the same as that in the medicine dispensing box 201b. The floating block 205n slides in the connecting barrel 205m and can float on the medicine liquid. The density of the floating block 205n can be 0.4~0.6 times that of water. A positioning bar is provided on the inner wall of 5m, which is used to limit the angle of the floating block 205n to prevent the floating block 205n from rotating in the connecting barrel 205m. The first driving block 205o and the second driving block 205p are both fixed to the surface of the slide rod 205k, and the first driving block 205o is located above the second driving block 205p. When the floating block 205n moves up and down in the connecting barrel 205m, the first driving block 205o and the second driving block 205p can drive the slide rod 205k to move up and down.

[0065] The position of the handle of the butterfly valve 203e shown in the figure is the state of the butterfly valve 203e being open. At this time, the water supply pipe 204c adds water to the medicine dispensing box 201b. At this time, the liquid level in the medicine dispensing box 201b rises, and the float 205n floats upward, driving the slide rod 205k to rise through the first driving block 205o, so that the slide rod 205k drives the fifth spring 205j to stretch. As the slide rod 205k rises, the slide rod 205k drives the paddle 205l to rise, so that the paddle 205l squeezes the slide column 205c, thereby driving the slide column 205c to move, so that the fourth spring 205e in the slide column 205c is stretched, and at the same time the slide column 205c drives the positioning hook 205d to move, so that the positioning hook 205d is moved. The positioning hook 205d releases the limit on the positioning column 205g. At this time, under the pulling force of the fifth spring 205j, the handle of the butterfly valve 203e can be driven to move, so that the handle of the butterfly valve 203e squeezes the upper positioning hook 205d, thereby causing the upper positioning hook 205d to slide. When the positioning column 205g on the butterfly valve 203e moves to the highest point, under the reset pulling force of the fourth spring 205e in the upper sliding column 205c, the positioning hook 205d can limit the positioning column 205g. At this time, the butterfly valve 203e is in a closed state, and the water flow in the water pipe 203b stops flowing to the drive shell 204a, causing the water supply pipe 204c to stop adding water to the medicine dispensing box 201b.

[0066] When the liquid in the medicine dispensing box 201b flows to the water tank 102 through the delivery pipe 201a, the liquid level in the medicine dispensing box 201b drops, and the floating block 205n moves downward, which can drive the slide bar 205k to move downward, so that the upper paddle 205l moves to the side of the upper slide column 205c. At this time, the pressure of the paddle 205l is not enough to drive the slide column 205c to move. When the floating block 205n moves to the side of the second driving block 205p, the second driving block 205p can drive the slide bar 205k to move downward, so that the slide bar 205k drives the paddle 205l to squeeze the slide column 205c, so that the slide column 205c drives the positioning hook 205d to move, thereby releasing the positioning hook 205d. The hook 205d limits the positioning column 205g. Under the pulling force of the fifth spring 205j, the handle of the butterfly valve 203e can be driven to move, so that the handle of the butterfly valve 203e squeezes the positioning hook 205d below, thereby causing the positioning hook 205d below to slide. When the positioning column 205g on the butterfly valve 203e moves to the lowest point, the positioning hook 205d can limit the positioning column 205g under the reset pulling force of the fourth spring 205e in the lower sliding column 205c. At this time, the butterfly valve 203e is in the open state, and the water flow in the water pipe 203b begins to flow to the drive shell 204a, causing the water supply pipe 204c to add water to the medicine dispensing box 201b.

[0067] Specifically, the drainage component 206 includes a third piston 206a, a push rod 206b, a support platform 206c, a sixth spring 206d, a connecting block 206e, a sealing block 206f and a drainage chamber 206g. The third piston 206a is arranged in the water supply pipe 204c, the push rod 206b is located at the bottom of the third piston 206a, the support platform 206c is arranged on the surface of the push rod 206b, the sixth spring 206d is located at the top of the support platform 206c, the connecting block 206e is located on one side of the water supply pipe 204c, the sealing block 206f is located at the end of the push rod 206b, and the drainage chamber 206g is arranged on the inner bottom wall of the medicine dispensing box 201b.

[0068] The water supply pipe 204c is provided with a through hole at one side of the third piston 206a for adding water to the medicine dispensing box 201b. The third piston 206a slides in the water supply pipe 204c. The push rod 206b is fixed to the bottom of the third piston 206a. The support platform 206c is fixed to the surface of the push rod 206b. The support platform 206c can limit the position of the push rod 206b. When the support platform 206c moves to the side of the water supply pipe 204c, the third piston 206a is at the top of its moving path. At the same time, the sealing block 206f is also at the top of its moving path. At this time, the sealing block 206f is 6f is still partially in the drainage chamber 206g, the two ends of the sixth spring 206d are respectively fixed to the top of the support platform 206c and the side of the connecting block 206e, the sixth spring 206d is in a stretched state, the connecting block 206e is fixed to one side of the water supply pipe 204c, the sealing block 206f is fixed to the end of the push rod 206b, the drainage chamber 206g is fixed to the bottom wall of the medicine dispensing box 201b and the drainage chamber 206g is connected to the delivery pipe 201a, which is used to transport the liquid in the medicine dispensing box 201b to the delivery pipe 201a, and the sealing block 206f is used to seal the flow channel of the drainage chamber 206g.

[0069] The state shown in the figure is that the water supply pipe 204c adds water to the medicine dispensing box 201b. At this time, the third piston 206a moves downward under the pressure of the water flow in the water supply pipe 204c, so that the through hole on the water supply pipe 204c can transport water to the medicine dispensing box 201b. At the same time, the third piston 206a drives the sealing block 206f to move downward through the push rod 206b, so that the sealing block 206f seals the flow channel of the drainage chamber 206g. At this time, the liquid in the medicine dispensing box 201b cannot be transported to the delivery chamber 206g. In the tube 201a, when the water supply pipe 204c stops adding water to the medicine dispensing box 201b, under the action of the reset tension of the sixth spring 206d, the push rod 206b drives the third piston 206a to move upward, blocking the through hole on the water supply pipe 204c, and at the same time the sealing block 206f moves upward, releasing the seal on the flow channel of the drainage chamber 206g, so that the liquid in the medicine dispensing box 201b is transported to the delivery pipe 201a through the drainage chamber 206g, and then enters the water tank 102.

[0070] When in use, in the state shown in the existing drawings, the water valve on the water pipe 203b is opened, and the water in the water pipe 203b begins to flow to the drive shell 204a. When the water pipe 203b supplies water to the drive shell 204a, the water flow drives the water wheel 204b to rotate, and the water in the drive shell 204a is transported to the dispensing box 201b through the water supply pipe 204c. The water wheel 204b can drive the support shaft 204d to rotate, and the support shaft 204d drives the turntable 204f to rotate, and the turntable 204f can drive the protrusion 204h to rotate, so that the protrusion 204h continuously presses the extrusion column 202k. The squeezing column 202k is squeezed and repeatedly moved in the support tube 202g, thereby continuously delivering the raw medicine liquid in the medicine box 202b to the dispensing box 201b. The position of the protrusion 204h can be adjusted by rotating the adjusting bolt 204g, thereby changing the amplitude of movement of the support tube 202g when the protrusion 204h squeezes the support tube 202g, thereby changing the speed at which the raw medicine liquid in the medicine box 202b is delivered to the dispensing box 201b, thereby changing the ratio of the raw medicine liquid to water, thereby changing the concentration of the dispensed medicine. At this time, the water supply pipe 204c adds water to the dispensing box 201b. At this time, the dispensing box 201b is dispensed with the water supply pipe 204c. The liquid level in the medicine box 201b rises, and the floating block 205n floats upward, driving the slide rod 205k to rise through the first driving block 205o, so that the slide rod 205k drives the fifth spring 205j to stretch. As the slide rod 205k rises, the slide rod 205k drives the paddle 205l to rise, so that the paddle 205l squeezes the slide column 205c, thereby driving the slide column 205c to move, so that the fourth spring 205e in the slide column 205c is stretched. At the same time, the slide column 205c drives the positioning hook 205d to move, so that the positioning hook 205d releases the limit on the positioning column 205g. At this time, the fifth spring 205e is pulled out of the position of the positioning hook 205d. 05j's pulling force can drive the handle of the butterfly valve 203e to move, so that the handle of the butterfly valve 203e squeezes the upper positioning hook 205d, thereby causing the upper positioning hook 205d to slide. When the positioning column 205g on the butterfly valve 203e moves to the highest point, the positioning hook 205d can limit the positioning column 205g under the reset pulling force of the fourth spring 205e in the upper sliding column 205c. At this time, the butterfly valve 203e is in a closed state, and the water flow in the water pipe 203b stops flowing to the drive shell 204a, causing the water supply pipe 204c to stop adding water to the medicine dispensing box 201b.

[0071] When the water supply pipe 204c stops adding water to the medicine dispensing box 201b, under the action of the reset tension of the sixth spring 206d, the push rod 206b drives the third piston 206a to move upward, blocking the through hole on the water supply pipe 204c. At the same time, the sealing block 206f moves upward, releasing the seal on the flow channel of the drainage chamber 206g, so that the liquid in the medicine dispensing box 201b is transported to the delivery pipe 201a through the drainage chamber 206g, and then enters the water tank 102, causing the liquid level in the medicine dispensing box 201b to drop.

[0072] When the liquid in the medicine dispensing box 201b flows into the water tank 102 through the delivery pipe 201a, the liquid level in the medicine dispensing box 201b drops, and the floating block 205n moves downward, which can drive the sliding rod 205k to move downward, so that the upper paddle 205l moves to the side of the upper slide column 205c. At this time, the pressure of the paddle 205l is not enough to drive the slide column 205c to move. When the floating block 205n moves to the side of the second driving block 205p, the second driving block 205p can drive the sliding rod 205k to move downward, so that the slide rod 205k drives the paddle 205l to squeeze the slide column 205c, so that the slide column 205c drives the positioning hook 205d to move, thereby releasing the restriction of the positioning hook 205d on the positioning column 205g. Under the pulling force of the fifth spring 205j, the handle of the butterfly valve 203e can be driven to move, so that the handle of the butterfly valve 203e is pressed against the positioning hook 205d below. The third piston 206a moves downward under the pressure of the water flow in the water supply pipe 204c, so that the through hole on the water supply pipe 204c can deliver water to the medicine dispensing box 201b. At the same time, the third piston 206a drives the sealing block 206f to move downward through the push rod 206b, so that the sealing block 206f seals the flow channel of the drainage cavity 206g. At this time, the liquid in the medicine dispensing box 201b cannot be delivered to the delivery pipe 201a.

[0073] Through the above process, automatic drug dispensing, automatic water addition, drug addition, and automatic supply of the configured drug solution to the water tank 102 can be achieved. The concentration of the drug solution can be adjusted to achieve real-time precise control. The drug concentration can be flexibly adjusted in different areas or at different times according to specific needs to provide better plant protection effects. At the same time, there is no need to return to the base, thereby improving work efficiency in agriculture, horticulture, and plant protection.
