Description

Technical Field

[0001] The invention relates to the technical field of liquid fertilizer fertilization, and in particular to liquid fertilizer and pesticide dual-purpose spraying equipment. Background Art

[0002] Liquid fertilizer is a liquid fertilizer that can be mixed with water to spray directly on the leaves or roots of plants, allowing the plants to absorb it more quickly. When the root absorption of crops is blocked, foliar fertilization can quickly replenish nutrients to meet the needs of crop growth and development. When crops are in urgent need of specific nutrients, soil fertilization takes a certain amount of time for the nutrients to be absorbed by the crops, and cannot alleviate the symptoms of nutrient deficiency in time. Foliar fertilization can allow nutrients to quickly enter the plant body through the leaves and solve the nutrient deficiency problem.

[0003] During the growth and development process, crops will be attacked by various pathogens, pests, weeds and rodents, which will affect their growth and survival, so pesticides are needed for prevention and control.

[0004] Generally, liquid fertilizer or pesticide spraying on crops is done separately, with liquid fertilizer spraying equipment and pesticide sprayer spraying on crops respectively, so the staff's workload is high and the operation is cumbersome; when spraying liquid fertilizer or pesticide on crops, it is necessary to prepare liquid fertilizer or pesticide and water in advance and store them in a liquid storage tank, and then spray the crops, but if too much is prepared and not used up, it will cause waste and pollute the environment, and if too little is prepared and not enough, it will need to be prepared multiple times, which is very troublesome, so we propose a liquid fertilizer and pesticide dual-purpose spraying equipment.

[0039] A liquid fertilizer storage cylinder 31 and a pesticide storage cylinder 32 are provided at the upper end of the liquid distribution box 3. The liquid inside the liquid fertilizer storage cylinder 31 and the pesticide storage cylinder 32 are transported to the inside of the liquid distribution box 3 through a liquid distribution mechanism 4. The liquid distribution mechanism 4 includes a liquid fertilizer distribution pipe 41 and a pesticide distribution pipe 42. The bottoms of the liquid fertilizer distribution pipe 41 and the pesticide distribution pipe 42 are both connected to the upper end of the liquid distribution box 3, and are controlled to be opened or closed at the same time by a second electromagnetic valve 43. One side of the bottom of the liquid fertilizer distribution pipe 41 and the pesticide distribution pipe 42 are respectively connected to the liquid fertilizer storage cylinder 31 and the pesticide storage cylinder 32, and are controlled to be opened or closed at the same time by a third electromagnetic valve 44.

[0040] A first telescopic rod 45 is provided between the liquid fertilizer dispensing pipe 41 and the pesticide dispensing pipe 42, and the first telescopic rod 45 is fixedly installed on the upper end of the dispensing box 3. A lifting plate 46 is provided at the output end of the first telescopic rod 45, and piston rods 47 are connected at both ends of the lifting plate 46. A fixing block 48 is provided at the bottom of the piston rod 47, and a piston block 49 is provided at the bottom of the fixing block 48. The piston block 49 is connected to the liquid fertilizer dispensing pipe 41 and the pesticide dispensing pipe 42 for sliding up and down. A thread 410 is provided near the upper end of the piston rod 47, and the piston rod 47 is connected to the lifting plate 46 through the thread 410. A knob 411 for adjusting the height of the piston block 49 is provided at the upper end of the piston rod 47;

[0041] The liquid fertilizer dispensing pipe 41 and the pesticide dispensing pipe 42 are both made of transparent materials, and a capacity scale 412 is provided on the outer diameter of the liquid fertilizer dispensing pipe 41 and the pesticide dispensing pipe 42. The liquid fertilizer storage cylinder 31 and the pesticide storage cylinder 32 are made of black opaque material, and a detachable sealing cover 35 is provided on the upper end of the liquid fertilizer storage cylinder 31 and the pesticide storage cylinder 32.

[0042] The liquid dispensing tank 3 is used to dispense liquid fertilizer and pesticide in real time. The liquid fertilizer and pesticide in the liquid fertilizer storage cylinder 31 and the pesticide storage cylinder 32 are transported to the liquid dispensing tank 3 through the liquid dispensing mechanism 4. Water is then added to the liquid dispensing tank 3 through the water supply tank 33. The liquid fertilizer and pesticide can be mixed in a certain proportion inside the liquid dispensing tank 3. The prepared liquid fertilizer and pesticide are then transported to the liquid storage barrel 2. The liquid storage barrel 2 is used to store the mixed liquid of the liquid fertilizer and the pesticide, and the mixed liquid is transported to the two spray heads 22 through the first water pump 21 for spraying the crops or flowers.

[0043] When the liquid level meter 36 at the bottom of the liquid storage barrel 2 detects that the liquid is less, the liquid is dispensed through the liquid dispensing mechanism 4. When dispensing, the first solenoid valve 23 and the second solenoid valve 43 are both in a closed state, and the third solenoid valve 44 is in an open state. The lifting plate 46 is driven to rise by the first telescopic rod 45. The lifting plate 46 drives the two piston rods 47 to rise at the same time, and drives the fixed block 48 and the piston block 49 installed at the bottom of the piston rod 47 to rise inside the liquid fertilizer dispensing pipe 41 and the pesticide dispensing pipe 42, so that the liquid fertilizer and pesticide in the liquid fertilizer storage cylinder 31 and the pesticide storage cylinder 32 are respectively drawn into the liquid fertilizer dispensing pipe 41 and the pesticide dispensing pipe 42. By setting the extraction capacity in advance, the liquid fertilizer and pesticide can be respectively set. The amount of liquid is extracted, and after the extraction is completed, the third solenoid valve 44 is closed, and then the second solenoid valve 43 is opened, and the first telescopic rod 45 drives the lifting plate 46 to descend, so that the piston rod 47 and the piston block 49 descend and squeeze the liquid extracted from the liquid fertilizer distribution pipe 41 and the pesticide distribution pipe 42 downward, so that the liquid inside the liquid fertilizer distribution pipe 41 and the pesticide distribution pipe 42 is pushed into the liquid distribution box 3, and at the same time, the water in the water supply tank 33 flows into the liquid distribution box 3 through the second water pump 34, so that the liquid fertilizer and the pesticide are mixed in the water. After the preparation is completed, the first solenoid valve 23 is opened, and the prepared solution enters the liquid storage barrel 2 for replenishment, so that the mixed solution of liquid fertilizer and pesticide in the liquid storage barrel 2 can be continuously supplied to the spray head 22;

[0044] In addition, the method for quantitatively extracting liquid fertilizer and pesticide is that the piston rod 47 can be raised or lowered by rotating the knob 411 at the upper end of the piston rod 47, so that the height of the piston block 49 inside the liquid fertilizer dispensing pipe 41 and the pesticide dispensing pipe 42 can be adjusted, and the piston block 49 is adjusted to a suitable position according to the capacity scale 412 on the liquid fertilizer dispensing pipe 41 and the pesticide dispensing pipe 42, so that the liquid can be quantitatively extracted. The liquid fertilizer dispensing pipe 41 and the pesticide dispensing pipe 42 are both made of transparent materials, which can facilitate the observation of the position of the piston block 49 and the liquid inside the liquid fertilizer dispensing pipe 41 and the pesticide dispensing pipe 42. The liquid fertilizer storage cylinder 31 and the pesticide storage cylinder 32 are made of black opaque materials, which can protect some liquid fertilizers and pesticides that cannot be exposed to light, and the unused liquid fertilizers and pesticides can be stored in the liquid fertilizer storage cylinder 31 and the pesticide storage cylinder 32 for a long time.

[0045] A first rotating arm 5 and a second rotating arm 51 are symmetrically arranged at the upper end of the base 1. The first rotating arm 5 and the second rotating arm 51 are controlled to open or close through an opening and closing mechanism 6. The opening and closing mechanism 6 includes a motor 61 fixedly mounted on the upper end of the base 1. A first gear 62 and a first synchronous wheel 63 are arranged at the output end of the motor 61. The first gear 62 and the first synchronous wheel 63 are located below the base 1. One end of the first rotating arm 5 is rotatably connected to the base 1 through a first rotating shaft 64. A second gear 65 is arranged at the lower end of the first rotating shaft 64. The second gear 65 is meshed and connected with the first gear 62. One end of the second rotating arm 51 is rotatably connected to the base 1 through a second rotating shaft 66. A second synchronous wheel 67 is arranged at the lower end of the second rotating shaft 66. The two first synchronous wheels 63 and the second synchronous wheels 67 are connected through a synchronous belt 68.

[0046] An orientation block 7 is rotatably installed on the upper side of the other end of the first rotating arm 5 and the second rotating arm 51. The orientation block 7 is controlled by an orientation mechanism 8 to always remain parallel to the central axis of the base 1. The orientation mechanism 8 includes a fixed plate 81 fixed to one end of the base 1. Two rows of guide rails 82 are provided on the upper end of the fixed plate 81. The upper end of the guide rails 82 is slidably connected to an orientation frame 83 through a slider. The orientation frame 83 is a U-shaped structure. An orientation rod 84 is provided on the inner side of the orientation block 7. The orientation rods 84 on the inner sides of the two orientation blocks 7 are staggered with each other up and down. The orientation rods 84 pass through both sides of the orientation frame 83 and are slidably connected to both sides of the orientation frame 83.

[0047] Among them, after the first rotating arm 5 and the second rotating arm 51 are opened, the distance between the spray head 22 and the crop or flower can be adjusted, so that the spray head 22 can have a good spraying range. When the first rotating arm 5 and the second rotating arm 51 are adjusted by the opening and closing mechanism 6, the motor 61 drives the first gear 62 and the first synchronous wheel 63 to rotate through the reducer, and the first gear 62 drives the second gear 65 to rotate, so that the first rotating arm 5 rotates, and at the same time, the first synchronous wheel 63 drives the second synchronous wheel 67 to rotate through the synchronous belt 68, so that the second rotating arm 51 rotates. Therefore, the first rotating arm 5 and the second rotating arm 51 can be driven to open or close at the same time through the opening and closing mechanism 6;

[0048] In addition, after the first rotating arm 5 and the second rotating arm 51 rotate, the spray head 22 installed at one end of the first rotating arm 5 and the second rotating arm 51 will rotate accordingly, so the spraying direction of the spray head 22 will rotate, thereby affecting the spraying effect. Therefore, by setting the directional block 7 and the directional mechanism 8, the spray head 22 can always maintain the same spraying direction. When the first rotating arm 5 and the second rotating arm 51 rotate, the directional rod 84 will slide on both sides of the directional frame 83, and drive the directional frame 83 to move on the guide rail 82. At the same time, the rotating shaft at the bottom of the directional block 7 rotates with the first rotating arm 5 and the second rotating arm 51, but the directional block 7 will always maintain the same direction after being controlled by the directional rod 84. Therefore, the spray head 22 installed at the upper end of the directional block 7 will not rotate with the first rotating arm 5 and the second rotating arm 51.

[0049] A spraying adjustment mechanism 9 is provided at the upper end of the directional block 7, and the spray head 22 is installed on the spraying adjustment mechanism 9. The spraying adjustment mechanism 9 includes an adjustment frame 91 fixed to the upper end of the directional frame 83, and a second telescopic rod 92 is fixedly installed on one side of the adjustment frame 91. A rack 93 is provided at the output end of the second telescopic rod 92, and the rack 93 is slidably connected to the bottom of the adjustment frame 91. A half gear 94 is provided at one end of the spray head 22, and both sides of the half gear 94 are rotatably installed on the inner side of the adjustment frame 91 through a rotating shaft, and the half gear 94 is meshed and connected with the rack 93.

[0050] Among them, the spray adjustment mechanism 9 is used to adjust the spraying angle of the spray head 22. Due to the different heights of crops or flowers, the spraying angle of the spray head 22 needs to be adjusted to achieve a better spraying effect. During adjustment, the rack 93 is driven to move by the second telescopic rod 92, so that the half gear 94 meshing with the rack 93 rotates, so that the spray head 22 rotates a certain angle, so that the angle of the spray head 22 can be adjusted.

[0051] The working principle and use process of the present invention:

[0052] When in use, the base 1 can be installed on a mobile vehicle body through the strip hole 12 on the base 1, which can be a wheelbarrow or a vehicle with a driving force. Liquid fertilizer and pesticide are mixed by the liquid mixing box 3 and the liquid mixing mechanism 4, and the liquid is transported to the liquid storage barrel 2 after mixing. The mixed liquid is then transported to the two spray heads 22 through the first water pump 21 to spray the crops or flowers. The liquid level meter 36 at the bottom of the liquid storage barrel 2 monitors the liquid in real time. When it is detected that the liquid is less, the liquid mixing mechanism 4 is used to mix the liquid to replenish the liquid storage barrel 2 in real time, so that the mixed solution of liquid fertilizer and pesticide in the liquid storage barrel 2 can be continuously supplied to the spray head 22. The first rotating arm 5 and the second rotating arm 51 are controlled by the opening and closing mechanism 6 to adjust the distance between the spray head 22 and the crops or flowers, so that the spray head 22 can have a good spraying range.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
