Technical Field

[0001] The present application relates to the technical field of gardening and agricultural machinery, and in particular to a pesticide sprayer. Background Art

[0002] With the development of agricultural mechanization, pesticide sprayers are an indispensable agricultural machinery in agricultural production. The use of efficient sprayers can save a lot of manpower and material resources to prevent crops from being harmed to varying degrees by diseases, insects, weeds, rodents, etc. during their growth. Among them, the most commonly used method for using chemical pesticides is spraying, which refers to a method of applying pesticides by mixing pesticides with water into an emulsion or suspension, and then using a pump to spray the liquid pesticide into a mist dispersion system.

[0003] In the related art, the pesticide sprayer includes a pot, a connecting hose and a spray rod. The pot is loaded with liquid pesticide and is provided with a shoulder strap for a worker to carry the pot. One end of the connecting hose is connected to the pot, and the other end is connected to the spray rod. When spraying pesticides, the worker can walk around with the pot on his back and spray the pesticide through the spray rod.

[0004] With regard to the above-mentioned related technologies, there is the method of one person using one pot, and the capacity of the pot is limited, which leads to the defect of low efficiency in spraying pesticides. Summary of the invention

[0005] In order to improve the efficiency of spraying pesticides, the present application provides a pesticide sprayer.

[0006] The present application provides a pesticide sprayer that adopts the following technical solution:

[0007] A pesticide spraying machine, comprising:

[0008] frame;

[0009] A medicine liquid tank, arranged on the frame;

[0010] A main pipe, connected to the medicine tank;

[0011] A control valve is arranged on the frame, the control valve has a water inlet valve port and a plurality of water outlet valve ports, the water inlet valve port is connected to an end of the main pipe away from the medicine water tank;

[0012] There are multiple branch pipes, and the multiple branch pipes are connected to the multiple water outlet valve ports respectively;

[0013] A plurality of spray bars are provided, and the plurality of spray bars are connected to the plurality of branch pipes.

[0014] By adopting the above technical solution, when it is necessary to spray pesticides, the sprayer is first placed at the predetermined position on site, then the medicine of the predetermined concentration is prepared in the medicine tank, and then the water inlet valve port and the water outlet valve port of the control valve are opened. Finally, multiple workers can hold multiple spray rods to spray pesticides at the same time. Compared with the single-person single-pot method, this design method can load more medicine in the medicine tank, and at the same time, only the length of the branch pipe needs to be lengthened to meet the predetermined size of the spraying area, thereby improving the spraying efficiency of the pesticide.

[0015] Preferably, the frame is provided with a pipeline winding mechanism at one end close to the medicine water tank, the pipeline winding mechanism includes a U-shaped mounting frame, a connecting shaft and a winding wheel, the U-shaped mounting frame is arranged on the frame; the connecting shaft is rotatably penetrated on one end of the bent opening of the U-shaped mounting frame; the winding wheel is provided with a rotating connecting hole for the connecting shaft to be fixedly penetrated, and the rotating connecting hole has a water inlet installation area at a position away from the connection between the connecting shaft and the U-shaped mounting frame; the branch pipe includes a stationary part, a rotating joint and a movable part, one end of the stationary part is connected to the water outlet valve port, and the other end is connected to the fixed part of the rotating joint; the fixed part of the rotating joint is connected to the U-shaped mounting frame, and the movable part of the rotating joint penetrates into the water inlet installation area; one end of the movable part is connected to the movable part of the rotating joint, and the other end passes through the water inlet installation area and is wound on the winding wheel, and the movable part also passes through the U-shaped mounting frame to be connected to the spray rod.

[0016] By adopting the above technical scheme, under the action of the pipeline winding mechanism and the branch pipe, on the one hand, during the spraying work, if the staff is getting farther and farther away from the medicine tank, the winding wheel can be gradually rotated to gradually release the movable part from the winding wheel. At the same time, in this process, because the movable part and the fixed part of the rotary joint will rotate relative to each other, the movable part will still remain connected with the stationary part during rotation, so as to maintain the normal spraying function of the spray rod. At the same time, compared with the branch pipe that cannot be wound, with this design, when multiple staff members are performing spraying work at the same time, the movable part in the branch pipe can be released to a predetermined length according to actual needs, so that it is not easy for multiple movable parts to be entangled, thereby reducing the mutual interference between multiple branch pipes, which helps the staff to use the equipment in an actual environment; on the other hand, after the spraying work is completed, the winding wheel can also be gradually rotated to gradually wind the movable part around the winding wheel, so as to better organize the sprayer.

[0017] Preferably, the frame has a first support block and two second support blocks at the pipe winding mechanism, the first support block and the second support blocks are vertically spaced apart, and the two second support blocks are symmetrically arranged relative to the one first support block; there are two pipe winding mechanisms, and the two pipe winding mechanisms are respectively located at the intervals between the two second support blocks and the one first support block; the bent bottom of the U-shaped mounting frame is for the movable part to pass through, one end of the bent opening of the U-shaped mounting frame is hinged to the second support block, and the other end of the bent opening of the U-shaped mounting frame is hinged to an installation telescopic rod; one end of the installation telescopic rod away from the U-shaped mounting frame is slidably connected to the first support block, and the U-shaped mounting frame can approach or move away from the first support block.

[0018] By adopting the above technical solution, when two workers are performing spraying work at the same time, the angle between the positions of the two workers and the connecting line formed by the medicine tank is between 0°-180°, so the connection method between the U-shaped mounting frame and the first support block and the second support block is that when the U-shaped mounting frame rotates around the connection with the second support block, the installed telescopic rod will gradually move along the outer surface of the first support block in the direction away from the medicine tank, and at the same time, the installed telescopic rod and the U-shaped mounting frame will also rotate relative to each other, so that the angle between the connecting shaft and the first support block can be changed, so that the opening direction of the U-shaped mounting frame can be changed. Therefore, in actual application, the worker can rotate the U-shaped mounting frame by pulling the movable part to make the opening direction of the U-shaped mounting frame adaptively adjusted relative to the position of the worker, so that when the worker sprays at different positions, the medicine can flow smoothly in the branch pipe to maintain the efficiency of the spraying work, and the two workers will not interfere with each other when spraying at their respective positions, which makes it more convenient for multiple people to use the device in actual applications.

[0019] Preferably, the lower surface of the first support block is slidably connected to a general mounting frame, and the sliding direction of the general mounting frame is parallel to the sliding direction of the installation telescopic rod; the connecting shaft includes a driven part, a driving telescopic part and a universal coupling part, and the driven part is rotatably inserted into the U-shaped mounting frame; the driving telescopic part is rotatably inserted into the general mounting frame, and the telescopic direction of the driving telescopic part is parallel to the telescopic direction of the installation telescopic rod; the two ends of the universal coupling part are respectively connected to the driven part and the driving telescopic part; the first support block is provided with a winding drive mechanism, and the winding drive mechanism is used to rotate the driving telescopic part.

[0020] By adopting the above technical solution, when the U-shaped mounting frame rotates in the direction away from the first support block, the main mounting frame will also move in the direction away from the medicine tank together with the mounting telescopic rod. At the same time, in this process, the driving telescopic part will gradually extend to adapt to the U-shaped mounting frame gradually moving away from the first support block, and due to the setting of the universal coupling part, the driven part and the driving telescopic part can maintain a transmission connection. Therefore, after the spraying work is completed, the staff can rotate the driving telescopic part through the winding drive mechanism, and the driving telescopic part rotates the driven part through the universal coupling part to rotate the winding wheel, so that the purpose of winding the movable part on the winding wheel can be achieved when the U-shaped mounting frame is in different postures, and thus the finishing work of the sprayer can be carried out more conveniently.

[0021] Preferably, the winding drive mechanism comprises:

[0022] An opening and closing slider is slidably connected to the general mounting frame, and the opening and closing slider can be close to or away from the driving telescopic part;

[0023] A main driving shaft, connected to the opening and closing sliding rotation;

[0024] There are two driving gears, and the two driving gears are sleeved on the main driving shaft at intervals;

[0025] There are two driven gears, which are respectively sleeved on the two driving telescopic parts, and the driven gears are meshed with the driving gears.

[0026] By adopting the above technical solution, before the staff carries out spraying, it is necessary to move the opening and closing slider in the direction away from the drive telescopic part until the active gear and the driven gear are disengaged, so that the main drive shaft and the drive telescopic part are released from the transmission connection, thereby interfering with the rotation of the two winding wheels, so that the two staff members can each carry out the spraying work; after the staff finishes spraying, first move the opening and closing slider in the direction close to the drive telescopic part until the active gear and the driven gear are engaged, so that the main drive shaft and the drive telescopic part form a transmission connection, and then the main drive shaft can be rotated to rotate the two drive telescopic parts, thereby achieving the purpose of rotating the winding wheel to allow the movable part to be wound on the winding wheel.

[0027] Preferably, an intermediate sleeve and a rotating bearing are connected between the main drive shaft and the opening and closing slider. The intermediate sleeve is passed through the opening and closing slider through the rotating bearing. The intermediate sleeve is used for the main drive shaft to slide through so that one pair of the driving gears can be disengaged from the driven gears.

[0028] By adopting the above technical solution, since the lengths of the movable parts sent out on the two winding wheels are not necessarily the same, after one of the winding wheels is stored, the main drive shaft can be moved along the axial direction of the main drive shaft until one of the pairs of driving gears is disengaged from the driven gear. At this time, when the main drive shaft continues to be rotated, only one of the driving telescopic parts will be rotated, thereby achieving the purpose of driving the two winding wheels to rotate together or one winding wheel to rotate alone, which helps to improve the adaptability of the sprayer to the actual application environment.

[0029] Preferably, the main mounting frame has a receiving cavity, and a manual operating mechanism is arranged in the receiving cavity, and the manual operating mechanism includes:

[0030] A connecting frame, wherein the main drive shaft is rotatably arranged through a bearing, the connecting frame is slidably connected in the accommodating cavity, and the sliding direction of the connecting frame is parallel to the axial direction of the main drive shaft;

[0031] A handle operating rod, one end of which is rotatably mounted on the connecting frame and the other end of which is inserted through the upper surface of the first supporting block;

[0032] An active worm gear connected to one end of the handle operating rod located in the accommodating cavity;

[0033] The driven worm wheel is fixedly sleeved on the main driving shaft, and the driven worm wheel is meshed with the driving worm.

[0034] By adopting the above technical solution, on the one hand, due to the setting of the handle operating lever, the active worm and the driven worm wheel, the staff can rotate the handle operating lever above the first support block, and realize the rotation of the total drive shaft under the cooperation of the active worm and the driven worm wheel; on the other hand, the self-locking property between the active worm and the driven worm wheel can be used to prevent the winding wheel from rotating under the influence of the outside world, thereby maintaining the stability of the equipment.

[0035] Preferably, a one-way wheel and a universal wheel are provided at the bottom of the frame, wherein two one-way wheels are provided and the two one-way wheels are located at a position of the frame close to the pipeline winding mechanism; and two universal wheels are provided and the two universal wheels are located at a position of the frame far away from the pipeline winding mechanism.

[0036] By adopting the above technical solution, on the one hand, with the cooperation of the one-way wheel and the universal wheel, the overall sprayer can be more convenient to move and carry. On the other hand, the positional relationship between the one-way wheel and the universal wheel can prevent the entire sprayer from rotating significantly when the worker pulls the U-shaped mounting frame to rotate, thereby making it less likely that the work of the two workers will interfere with each other.

[0037] In summary, the present application includes at least one of the following beneficial technical effects:

[0038] 1. Through the arrangement of the rack, the medicine tank, the main pipe, the control valve and the branch pipe, compared with the single-person single-pot method, this design method can load more medicine in the medicine tank, and at the same time, only the length of the branch pipe needs to be lengthened to meet the predetermined spraying area, thereby improving the spraying efficiency of pesticides;

[0039] 2. Through the arrangement of the pipe winding mechanism and the branch pipe including the stationary part, the rotating joint and the movable part, when multiple workers are spraying at the same time, the movable part in the branch pipe can be released to a predetermined length according to actual needs, so that it is not easy for multiple movable parts to be entangled, thereby reducing the mutual interference between multiple branch pipes, which helps the workers to use the equipment in actual environments; on the other hand, after the spraying work is completed, the winding wheel can be gradually rotated so that the movable part is gradually wound on the winding wheel, so that the sprayer can be better organized.

When the staff is farther and farther away from the position of the medicine tank 2, the winding wheel 73 can gradually release the movable part 53 of a predetermined length, so that the two branch pipes 5 are not easy to interfere with each other. At the same time, during the rotation of the winding wheel 73, the stationary part 51 and the movable part 53 can always remain connected through the rotating joint 52, thereby maintaining the normal spraying function of the spray rod 6.

[0051] Reference Figure 1 and Figure 2In actual application, the angle between the positions of the two workers and the line connecting the medicine tank 2 is between 0° and 180°. Therefore, in order to reduce the mutual interference between the two workers during spraying, in the present embodiment, one end of the bent opening of the U-shaped mounting frame 71 is hinged to the second support block 12, and the other end of the bent opening is hinged to a mounting telescopic rod 711, wherein the mounting telescopic rod 711 is in the form of a multi-section telescopic structure, and the end of the mounting telescopic rod 711 away from the U-shaped mounting frame 71 is slidably connected to the vertical outer surface of the first support block 11, and the mounting telescopic rod 711 can move in a direction close to or away from the medicine tank 2, so as to improve the connection stability between the U-shaped mounting frame 71 and the frame 1 while enabling the U-shaped mounting frame 71 to change its own opening direction. When spraying, the worker can rotate the U-shaped mounting frame 71 by pulling the movable part 53, so that the opening direction of the U-shaped mounting frame 71 is adaptively adjusted relative to the position of the worker, so that the worker can stably perform spraying work at different positions, and the two workers will not interfere with each other when spraying at their respective positions.

[0052] Reference Figure 1 and Figure 2 In order to be able to reel up the reel 73, in this embodiment, the sprayer is provided with corresponding arrangements.
