[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] like Figures 1 to 3 As shown, an embodiment of the present invention provides a sprayer, which includes a main body 10, a medicine bottle 20 and a spraying part 30. The main body 10 includes a box body 11 and a driving member arranged in the box body 11, and the box body 11 has a placement position; the medicine bottle 20 is detachably arranged at the placement position; the spraying part 30 includes a spray rod 31 and a nozzle 32 arranged on the spray rod 31, and both ends of the driving member are connected to the medicine bottle 20 and the spray rod 31 respectively, and the driving member can transport the medicine in the medicine bottle 20 to the spray rod 31.

[0027] Using the technical solution of the present invention, the sprayer includes a main body 10, a medicine bottle 20 and a spraying part 30. When using the sprayer, firstly, the prepared medicine is placed in different medicine bottles 20 according to the type, and the medicine bottle 20 is placed at the placement position of the box body 11. The medicine in the medicine bottle 20 is transported to the spray rod 31 by a driving member, and the medicine is sprayed into the field by a nozzle 32 connected to the spray rod 31. After the spraying of one kind of medicine is completed, the medicine bottle 20 is removed from the placement position, replaced with another kind of medicine bottle 20, and sprayed into the field again. With the above-mentioned sprayer, since there is no need to clean the medicine pot at the experimental site, only the plastic bottle with liquid medicine treatment prepared in advance needs to be replaced, thereby improving the experimental efficiency. In addition, there will be no residual medicine affecting the experimental effect.

[0028] It should be noted that after replacing a new medicine bottle 20, the medicine in the medicine bottle 20 should first be transported to the spray rod 31 using the driving member and sprayed out using the nozzle 32. This part of the sprayed medicine cannot be sprayed on the field. The purpose is to use the medicine in the medicine bottle 20 to clean the spray rod 31 and the nozzle 32 to avoid affecting the efficacy of the medicine.

[0029] In this embodiment, a handle is provided on the upper surface of the box body 11 to facilitate the operator to lift it.

[0030] The outer wall of the box body 11 has a vertically arranged placement tube and a support plate below the placement tube, and the medicine bottle is placed in the placement tube and abuts against the support plate. The above structure is used to place the medicine bottle, which has the advantages of simple structure and easy processing.

[0031] like Figure 2 As shown, the driving member includes a driving pump 12, and the main body 10 also includes a power supply 13 disposed in the box body 11, and the power supply 13 is electrically connected to the driving pump 12. The method of using the power supply 13 to drive the driving pump 12 has the advantages of being convenient and fast.

[0032] Compared with the related art that uses carbon dioxide pressure gas cylinders as the driving method, this precision sprayer uses electric power, which is more convenient and quick. When the sprayer shows that the battery is low, the battery can be charged, which is convenient and efficient, eliminating the trouble of going to a special gas station to fill the cylinder. In addition, the sprayer is light in weight and small in size, which is easy to carry and operate.

[0033] In the related art, since a backpack sprayer is used for spraying pesticides, in addition to the weight of the backpack sprayer itself, the liquid medicine loaded therein also needs to be correspondingly large to spray the liquid medicine, which is heavy and not easy to carry, increasing the difficulty of operation. Alternatively, a carbon dioxide pressure gas cylinder is used as a driving method, and the user needs to carry a heavy carbon dioxide cylinder. The sprayer uses a small-volume medicine bottle 20 to hold the pesticide liquid for processing, which is light in weight and small in size, and is convenient to carry and operate.

[0034] like Figure 1 As shown, a speed control switch 111 is provided on the box body 11, and the speed control switch 111 is connected to the driving pump 12 to control the output power of the driving pump 12. The speed control switch 111 is used to adjust the output power of the driving pump 12, thereby adjusting the flow rate of the agent to adjust the spraying speed of different types of agents.

[0035] like Figure 1 As shown, a control switch 112 is provided on the box body 11, and the control switch 112 is connected to the driving pump 12 to control the working state of the driving pump 12. The control switch 112 can make the driving pump 12 work under the rated power state, so as to achieve the maximum medicine spraying speed.

[0036] In this embodiment, the sprayer has a first working mode and a second working mode. In the first working mode, the control switch 112 is turned on and the drive pump 12 works at the rated power state. In the second working mode, the control switch 112 is turned off, and the output power of the drive pump 12 can be gradually changed by adjusting the speed control switch 111, so that the spray speed of the medicine is steadily increased until the desired working state is reached.

[0037] like Figure 1 As shown, the spray rod 31 is provided with a stop valve 311 and a pressure rod 312, the pressure rod 312 is movably provided on the spray rod 31, and the pressure rod 312 is drivingly connected to the stop valve 311 to control the working state of the stop valve 311. The stop valve 311 can be used to control the flow rate of the medicine in the spray rod 31, and the pressure rod 312 can be used to control the working state of the stop valve 311.

[0038] like Figure 1 As shown, a limiter is provided on the pressure rod 312, the stop valve 311 includes a valve body and a valve stem movably provided in the valve body, the valve body is provided on the spray rod 31, the pressure rod 312 is drivingly connected to the valve stem, the pressure rod 312 has a pressing state for pressing the valve stem and an initial state for returning to an initial position, when the pressure rod 312 is in the pressing state, the limiter can cooperate with the valve body in limiting position. The use of the limiter can keep the pressure rod 312 in the pressing state, which has the advantage of simple structure.

[0039] When the pressing rod 312 is in the initial state, the stop valve 311 is in the closed state.

[0040] In this embodiment, the limiting member includes a limiting ring, which is movably arranged on the pressure rod 312. A protrusion is arranged on the outer wall of the valve body, and the limiting ring can cooperate with the protrusion. The limiting ring and the protrusion are used to limit the pressure rod 312 so that the pressure rod 312 is in a pressing state, which has the advantages of simple structure and easy setting.

[0041] like Figure 1As shown, the spray bar 31 is also provided with a flow regulating valve 313, which is located downstream of the stop valve 311. The flow regulating valve 313 is used to adjust the flow of the agent in the spray bar 31, which has the advantages of simple structure and easy adjustment.

[0042] In this embodiment, the sprayer also has a third working mode and a fourth working mode. In the third working mode, the operator can open the stop valve 311 at any time by pressing the pressure rod 312 on the spray rod 31 to control the flow of the medicine in the spray rod 31 at any time. When pressed, the stop valve 311 opens and the liquid can flow out. When the pressure rod 312 is released, it automatically rebounds, and the stop valve 311 is closed to block the flow of liquid. In the fourth working mode, by pressing the pressure rod 312, the limit ring and the raised limit are matched. At this time, the pressure rod 312 cannot automatically rebound, the stop valve 311 is in an open state, and the liquid can flow out at a uniform speed. In addition, in the fourth working mode, the flow control of the liquid medicine is achieved by controlling the flow regulating valve 313, and the flow control range is 0 to the maximum value.

[0043] Specifically, the flow regulating valve 313 is a ball valve.

[0044] like Figure 1 As shown, there are multiple medicine bottles 20 and placement positions, and the volumes of the multiple medicine bottles 20 are different. The multiple medicine bottles 20 are arranged in the placement positions one by one. Using multiple medicine bottles 20, different types of medicines can be contained, and at the same time, appropriate amounts of medicines can be contained according to the types of medicines.

[0045] In this embodiment, there are two medicine bottles 20, one with a volume of 0.5 L and the other with a volume of 2.5 L. Before the experiment, the user can choose a plastic bottle of 0.5 L to 2.5 L as needed and prepare the liquid medicine in advance.

[0046] In the related art, the area of ​​the field experiment plot is relatively small, usually 3 to 15 square meters, and the amount of medicine used in each plot is very small. In addition, in the pesticide efficacy experiment, it is often necessary to compare the efficacy of multiple chemical agents or pesticides of different dosages, so the number of experimental liquid treatments is often large. Compared with the large-volume medicine pot, the present invention uses a small-volume plastic medicine bottle to easily save liquid medicine.

[0047] like Figure 1 As shown, the sprayer also includes a rubber tube 40, and the medicine bottle 20 and the spray rod 31 are both connected to the drive pump 12 through the rubber tube 40. The use of the rubber tube 40 to connect the drive pump 12 and the medicine bottle 20, the drive pump 12 and the spray rod 31 has the advantages of easy material acquisition and low cost.

[0048] In this embodiment, the rubber tube 40 is detachably connected to the driving pump 12 , the medicine bottle 20 and the spray rod 31 .

[0049] Specifically, the medicine bottle 20 includes a bottle body 21 and a bottle cap 22 that are detachably connected. The bottle body 21 is set at a placement position, and the rubber tube 40 is passed through the bottle cap 22. A breathing valve is provided on the bottle cap 22. The breathing valve can balance the pressure inside and outside the bottle body 21, so as to facilitate the extraction of the medicine in the bottle body 21 to the drive pump 12.

[0050] In this embodiment, there is one bottle cap 22, and the bottle cap 22 is sleeved on the rubber tube.

[0051] Among them, the spray rod 31 includes a conveying section 314 and a spraying section 315 that are connected to each other. There is an angle between the conveying section 314 and the spraying section 315. The conveying section 314 is connected to the rubber tube 40. There are multiple nozzles 32, and the multiple nozzles 32 are arranged at intervals along the extension direction of the spraying section 315. With the above structure, the nozzles 32 can be arranged in multiple numbers, thereby increasing the coverage area of ​​the spraying agent by the spray rod 31 to improve work efficiency.

[0052] In this embodiment, the box body 11 is provided with a display 113 which is electrically connected to the power source 13 and displays the power level of the power source 13. The display 113 can be used to conveniently observe the power level of the power source 13 so as to charge it in time without affecting the use of the sprayer.
