[0002] Agricultural machinery, i.e. agricultural machinery, is used in the fields of planting, animal husbandry, agricultural product processing / transportation and farmland infrastructure, etc. When performing pesticide application on crops, a pesticide spraying agricultural machine is usually used for spraying.

[0003] The amount of pesticide applied to crops needs to be determined according to the variety of crops, the growth stage of crops, etc. The spray head structure equipped on the pesticide spraying agricultural machine in the prior art is relatively simple, usually being a fixed structure or a manually adjustable flow structure, which is not convenient for adaptive adjustment of the flow of liquid medicine spraying according to the actual pesticide demand of crops. Different pesticide spraying agricultural machines are usually needed according to the variety of crops, the growth stage of crops, etc., which is inconvenient to use and has a high cost. SUMMARY

[0004] In view of the deficiencies in the prior art, the utility model provides a high-precision flow regulation formula spraying system capable of adjusting the flow of liquid medicine spraying. The utility model also provides a pesticide application agricultural machine comprising the high-precision flow regulation formula spraying system.

[0005] The utility model solves the above technical problems by using the following technical scheme:

[0006] A high-precision flow regulation formula spraying system comprises a water pipe, a spray head body is arranged at the bottom of the water pipe, spray pipes are fixedly installed on both sides of the spray head body, a nozzle is arranged at one end of the spray pipe, a flow regulating mechanism is arranged on the spray pipe, the flow regulating mechanism comprises fixed frames fixedly installed symmetrically at the top and bottom of the spray pipe, a first electric telescopic rod is arranged in the fixed frame, and two adjusting blocks connected to the first electric telescopic rod are symmetrically arranged in the interior of the spray pipe.

[0007] Further, two fixed blocks are fixedly installed symmetrically on the surface of the water pipe, a spring is arranged in the fixed block, a clamping rod is arranged at one end of the spring, and two clamping blocks are fixedly installed symmetrically on the spray head body.

[0008] Further, the diameter of the clamping rod is consistent with the inner diameter of the clamping groove on the clamping block, and one end of the clamping rod is arranged in an arc shape.

[0009] Further, a sealing gasket is fixedly installed on the top of the spray head body and the surface of the adjusting block.

[0010] Furthermore, a threaded sleeve that is threadedly connected to the nozzle is fixedly installed on the surface of the nozzle.

[0011] Furthermore, multiple anti-slip blocks are uniformly and fixedly installed on the surface of the nozzle.

[0012] Furthermore, multiple second electric telescopic rods are fixedly installed at the top and bottom of the nozzle, and two baffles connected to the second electric telescopic rods are symmetrically arranged on one side of the nozzle.

[0013] A pesticide application machine includes the aforementioned high-precision flow rate adjustable spraying system.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] The high-precision flow rate adjustable spraying system of this application can precisely adjust the flow rate of the sprayed pesticide solution through the setting of the flow rate adjustment mechanism. At the same time, the two first electric telescopic rods are activated to extend and retract their output ends, which in turn drives the two adjusting blocks to rise and fall inside the spray pipe, changing the flow orifice diameter inside the spray pipe. By changing the flow orifice diameter, the flow rate of the pesticide solution is changed, so that the spraying system can spray according to the pesticide application needs of the crops, which helps to improve the application effect of pesticides on crops and avoid the impact of excessive or insufficient pesticide application on crop growth.

[0021] The technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings and specific embodiments.

[0022] like Figs. 1-4As shown, this embodiment provides a high-precision flow rate adjustable spraying system, which includes a water pipe 1, a nozzle body 2 at the bottom of the water pipe 1, spray pipes 3 fixedly installed on both sides of the nozzle body 2, a nozzle 4 at one end of the spray pipe 3, and a flow rate adjustment mechanism 5 on the spray pipe 3. The flow rate adjustment mechanism 5 includes a fixing frame 6 symmetrically fixedly installed at the top and bottom of the spray pipe 3, a first electric telescopic rod 7 inside the fixing frame 6, and two adjusting blocks 8 symmetrically arranged inside the spray pipe 3 and connected to the first electric telescopic rod 7.

[0023] In this embodiment, as Figs. 1-4 As shown, two fixing blocks 9 are symmetrically fixedly installed on the surface of the water pipe 1. A spring 10 is installed inside each fixing block 9, and a locking rod 11 is attached to one end of each spring 10. Two locking blocks 12 are symmetrically fixedly installed on the nozzle body 2. The diameter of the locking rod 11 matches the inner diameter of the slot on the locking block 12, and one end of the locking rod 11 is arc-shaped. The water pipe 1 and the nozzle body 2 are installed by engaging the locking rod 11 and the locking block 12. Because the locking rod 11 is supported by the spring 10, the engagement between the locking rod 11 and the locking block 12 has a certain degree of flexibility, allowing the locking rod 11 to detach from the locking block 12, facilitating the disassembly and replacement of the nozzle body 2. Matching the diameter of the locking rod 11 with the inner diameter of the slot on the locking block 12 makes the engagement between the locking rod 11 and the locking block 12 more stable, preventing the nozzle body 2 from shaking. Simultaneously, the arc-shaped design of one end of the locking rod 11 facilitates the locking block 12's compression of the locking rod 11 during assembly and disassembly.

[0024] Sealing gaskets 13 are fixedly installed on the top of the nozzle body 2 and the surface of the adjusting block 8. The sealing gaskets 13 can increase the sealing between the adjusting block 8 and the nozzle 3 and between the nozzle body 2 and the water pipe 1, and prevent liquid leakage.

[0025] In this embodiment, as Figs. 1-4 As shown, a threaded sleeve 14 that is threadedly connected to the nozzle 4 is fixedly installed on the surface of the spray pipe 3; a plurality of anti-slip blocks 15 are evenly fixedly installed on the surface of the nozzle 4; the nozzle 4 is installed on one side of the spray pipe 3 by threading the threaded sleeve 14 to the nozzle 4, so that the nozzle 4 can be disassembled from one side of the spray pipe 3, which is convenient for replacing the nozzle 4 according to the spraying requirements to adjust the atomization degree during spraying; the anti-slip blocks 15 can increase the friction of the nozzle 4 surface, which is convenient for twisting and rotating when disassembling and assembling the nozzle 4.

[0026] Multiple second electric telescopic rods 16 are fixedly installed at the top and bottom of the nozzle 3. Two baffles 17 connected to the second electric telescopic rods 16 are symmetrically arranged on one side of the nozzle 4. When not in operation, the two second electric telescopic rods 16 are activated simultaneously to retract their output ends, causing the two baffles 17 to move and close on one side of the nozzle 4, thus protecting the nozzle 4.

[0027] This embodiment also provides a pesticide application machine, which includes the aforementioned high-precision flow rate adjustable spraying system.

[0028] like Figs. 1-4 As shown in the figure, the working process of the high-precision flow rate adjustable spraying system provided in this embodiment is as follows:

[0029] The high-precision flow rate regulating spraying system, through the flow rate regulating mechanism 5, can precisely regulate the flow rate of the sprayed pesticide. Simultaneously, the two first electric telescopic rods 7 are activated to extend and retract their output ends, thereby driving the two regulating blocks 8 to rise and fall inside the spray pipe 3. This changes the flow orifice diameter inside the spray pipe 3, thereby changing the flow rate of the pesticide. This allows the spraying system to spray according to the pesticide requirements of the crops, which helps to improve the pesticide application effect on the crops and avoids the impact of excessive or insufficient pesticide application on crop growth.
