[0019] With the development of agricultural mechanization, pesticide spraying machines have become an indispensable mechanical equipment in agricultural production. The traditional spraying equipment usually includes liquid tank, plunger pump, hose and other structures, but there are some obvious shortcomings in actual use. For example, the hose is time-consuming and laborious to store, and is easy to entangle and knot; it cannot realize multi-angle steering and guidance when pulling and paying off the line, which leads to easy wear or damage of the hose; in addition, the degree of automation of the equipment is low, and the pipe reel and the plunger pump cannot be controlled independently, which further reduces the use efficiency. In order to solve these problems, an improved pesticide spraying machine is proposed.

[0020] The pesticide spraying machine of the present application solves the problems of time-consuming and laborious hose storage, easy entanglement and knotting, and inability to realize multi-angle steering and guidance when pulling and paying off the hose. Specifically, the device includes a rack 1, the bottom of which is provided with a liquid tank 2 for storing liquid; the upper part is provided with a plunger pump 3 and a pipe reel, the plunger pump 3 is used to deliver liquid from the liquid tank 2 to the spray head, and the pipe reel 4 is used to store the hose 7; the lower part is provided with a spray head support 5 and a vehicle hanging support 6. The top of the pipe reel 4 is equipped with a reciprocating pipe discharger 8 and a 360° pipe guide 9, which can effectively prevent the hose 7 from entangling and knotting, and realize multi-angle steering and guidance. By setting the transmission structure of driven wheels one 10, driven wheels two 11 and driven wheels three 12 on the rack 1, the synchronous operation of the plunger pump 3 and the pipe reel 4 is realized, and the operation of the two is controlled by the plunger pump clutch 13 and the pipe reel clutch 14 respectively. Therefore, the device has been significantly improved in automation and operation convenience.

[0021] In the design process, the key terms and implementation environment of the device are fully considered. The plunger pump 3 is a high-efficiency liquid delivery device, the inlet of which is communicated with the liquid tank 2, and the outlet is connected with the front end of the hose 7, which ensures that the liquid can be smoothly delivered to the spray head. The hose 7 is communicated with the spray head through the 360° pipe guide 9, and the rotation base 18 and guide wheel set 19 of the pipe guide are designed to enable the hose 7 to be flexibly adjusted in different directions, avoiding the problems of wear and knotting of the hose 7 in traditional design. The reciprocating pipe discharger 8 further optimizes the storage process of the hose 7 through the cooperation of the lead screw and the slide block 17. The transmission mechanism adopts multi-stage linkage design of driven wheels, which is driven by external power, so as to realize efficient cooperative work of the plunger pump 3 and the pipe reel 4.

[0022] Specifically, the liquid medicine barrel 2 is used for storing liquid medicine, the plunger pump 3 is connected with the liquid medicine barrel 2 through the liquid inlet, and the liquid medicine is delivered to the hose 7. One end of the hose 7 is connected with the liquid outlet of the plunger pump 3, and the other end is connected with the spray head through the 360° conduit device 9. The rotating base 18 and the guide wheel set 19 of the conduit device are designed to enable the hose 7 to be flexibly adjusted in direction, avoiding the problems of wear and knotting of the hose 7 in the traditional design. The hose reel 4 is used for winding the hose 7, and the reciprocating pipe discharger 8 arranged at the top of the hose reel 4 works through the cooperation of the screw rod and the sliding block 17, further optimizing the winding process of the hose 7. The transmission mechanism adopts a multi-stage linkage design of driven wheels, the first driven wheel 10 is driven by external power, driving the second driven wheel 11 and the third driven wheel 12 to rotate, thereby realizing efficient collaborative work of the plunger pump 3 and the hose reel 4. The plunger pump clutch 13 and the hose reel clutch 14 control the operation of the plunger pump 3 and the hose reel 4 respectively, making the operation of the equipment more convenient.

[0023] Compared with the prior art, the pesticide spraying machine of the present application has achieved significant improvement in many aspects. In the traditional equipment, the winding and unwinding process of the hose 7 is time-consuming and laborious, and is prone to winding and knotting problems, while the present application effectively solves these problems by introducing the reciprocating pipe discharger 8 and the 360° conduit device 9. In addition, in the traditional equipment, the hose reel and the plunger pump 3 cannot be controlled independently, and the operation is complex, while the present application realizes the independent control of the two through the design of the plunger pump clutch 13 and the hose reel clutch 14, significantly improving the automation degree and use efficiency of the equipment. Through the multi-stage linkage design of the driven wheels, the equipment can efficiently complete the spraying work, further improving the convenience and efficiency of agricultural production.

[0024] The pesticide spraying machine of the present application successfully solves the problems of time-consuming and laborious winding of the hose 7, easy winding and knotting, and inability to realize multi-angle steering and guiding when the hose 7 is pulled and unwound in the use process of the traditional equipment through the combination of multiple innovative features. Specifically, the liquid medicine barrel 2 is used for storing liquid medicine, the plunger pump 3 is connected with the liquid medicine barrel 2 through the liquid inlet, and the liquid medicine is delivered to the hose 7. One end of the hose 7 is connected with the liquid outlet of the plunger pump 3, and the other end is connected with the spray head through the 360° conduit device 9. The rotating base 18 and the guide wheel set 19 of the conduit device are designed to enable the hose 7 to be flexibly adjusted in direction, avoiding the problems of wear and knotting of the hose 7 in the traditional design. The hose reel 4 is used for winding the hose 7, and the reciprocating pipe discharger 8 arranged at the top of the hose reel 4 works through the cooperation of the screw rod and the sliding block 17, further optimizing the winding process of the hose 7. The transmission mechanism adopts a multi-stage linkage design of driven wheels, the first driven wheel 10 is driven by external power, driving the second driven wheel 11 and the third driven wheel 12 to rotate, thereby realizing efficient collaborative work of the plunger pump 3 and the hose reel 4. The plunger pump clutch 13 and the hose reel clutch 14 control the operation of the plunger pump 3 and the hose reel 4 respectively, making the operation of the equipment more convenient.

[0025] Through the above technical solutions, the pesticide spraying machine of the present application not only improves the storage efficiency and service life of the hose 7, but also significantly improves the automation degree and operation convenience of the equipment.

[0026] In embodiment two, based on the structure of embodiment one, the present application further proposes that the plunger pump 3 adopts a three-cylinder plunger pump.

[0027] The design of the three-cylinder plunger pump for the plunger pump 3 can significantly improve the spraying efficiency and uniformity of the spraying machine through the synchronous work of the multi-cylinder structure. The multi-cylinder design of the three-cylinder plunger pump enables the plunger cylinders to work at different time points, thereby realizing continuous and smooth spraying process and avoiding the intermittent phenomenon that may occur in the spraying process of a single-cylinder plunger pump. This design optimizes the fluidity of the liquid, reduces pressure fluctuations, helps the uniform distribution of the pesticide liquid, and improves the spraying effect.

[0028] Specifically, the three-cylinder plunger pump can be optimized through various implementation methods. For example, an equidistantly arranged three-cylinder plunger structure can be adopted to ensure that the working periods of the plunger cylinders are evenly distributed, thereby realizing smooth pressure output. In addition, the material of the plunger cylinder can be optimally selected, such as using corrosion-resistant materials, to improve the service life and adaptability of the pump body. As a preferred embodiment, a pressure regulating device can also be added to the design of the plunger pump 3 to further optimize the spraying effect. For power input, a belt drive or direct connection to an external power device can be used to ensure stable operation of the plunger pump 3.

[0029] Therefore, by adopting the three-cylinder plunger pump, the present application can effectively solve the problems of low spraying efficiency and poor spraying uniformity in the prior art. Compared with the prior art, the present application provides a new structure design that can significantly improve the spraying efficiency and uniformity, and has high practical value. The design of the three-cylinder plunger pump not only improves the performance of the spraying machine, but also enhances the reliability and durability of the equipment, meeting the demand for high-efficiency spraying equipment in agricultural production.

[0030] In embodiment three, based on embodiment one, the present application further proposes that wheels 15 are installed at the bottom of the rack 1.

[0031] By installing wheels 15 at the bottom of the rack 1, the pesticide spraying machine can be moved more conveniently. This design effectively solves the problem of inconvenient movement of the pesticide spraying machine during use, improving the flexibility and operation efficiency of the equipment. The installation of the wheels 15 enables the spraying machine to easily roll on the ground, thereby reducing the labor intensity of the operator and improving the work efficiency.

[0032] On the basis of understanding the installation of wheels 15 at the bottom of the frame 1, this technical feature can be implemented in various ways. For example, the wheels 15 can be fixed or rotatable, and the specific choice can be determined according to the terrain conditions and use requirements. As a preferred embodiment, the wheels 15 can be made of wear-resistant materials to increase their service life. In addition, the size and number of wheels 15 can also be adjusted according to the size and weight of the spraying machine to ensure the stability and safety of movement.

[0033] By installing wheels 15 at the bottom of the frame 1, the design of the present application makes the movement of the pesticide spraying machine more convenient, significantly improving the operational flexibility and use efficiency of the equipment compared with the prior art. This improvement reduces the physical exertion of the operator during pesticide spraying and helps to complete the spraying task more efficiently. Thus, the problem of inconvenient movement existing in the prior art is solved, and a more comfortable user experience is provided.

[0034] In embodiment four, on the basis of embodiment one, the present application further proposes that the plunger pump 3 comprises a liquid return port, and the liquid return port is in communication with the pesticide liquid barrel 2.

[0035] The plunger pump 3 comprises a liquid return port, and the liquid return port is in communication with the pesticide liquid barrel 2. The function of the liquid return port is to enable the excess pesticide liquid to flow back to the pesticide liquid barrel 2 during the working process of the plunger pump 3, thereby avoiding the problems of waste of pesticide liquid or excessive pressure. Through this design, the use efficiency of the pesticide spraying machine can be effectively improved, and the loss of pesticide liquid can be reduced. Through the technical scheme of adding a liquid return port in the plunger pump 3 and communicating with the pesticide liquid barrel 2, the problem that the pesticide liquid cannot flow back during the working process of the plunger pump 3 is solved, ensuring the stability of the equipment operation, and optimizing the use and management of the pesticide liquid.

[0036] The liquid return port can be implemented in various ways. For example, the liquid return port can be provided on the side or bottom of the plunger pump 3 and communicated with the pesticide liquid barrel 2 through a pipeline. Further, the liquid return port can be provided with a one-way valve to ensure that the pesticide liquid can only flow back from the plunger pump 3 to the pesticide liquid barrel 2, but cannot flow in the opposite direction. In addition, the diameter of the liquid return port can be adjusted according to the flow rate of the plunger pump 3 and the viscosity of the pesticide liquid to ensure that the pesticide liquid can flow back smoothly. As a preferred embodiment, the liquid return port can be made of corrosion-resistant materials to improve its service life and reliability.

[0037] Through the technical scheme of adding a liquid return port in the plunger pump 3 and communicating with the pesticide liquid barrel 2, the problem that the pesticide liquid cannot flow back during the working process of the plunger pump 3 is solved. Compared with the prior art, the technical scheme of the present application can effectively avoid the problems of waste of pesticide liquid and excessive pressure, improve the use efficiency of the pesticide spraying machine, reduce the loss of pesticide liquid, and ensure the stability of the equipment operation. This design optimizes the use and management of the pesticide liquid, improves the automation degree and reliability of the pesticide spraying machine.

[0038] In addition to the above, the application further proposes that the driving force is transmitted between the driven wheels one 10, the driven wheels two 11 and the driven wheels three 12 through a belt drive.

[0039] By adopting a belt drive between the driven wheels, the transmission efficiency and stability can be improved. The belt drive can reduce the friction and wear between mechanical components, thereby prolonging the service life of the equipment and reducing the maintenance cost. By adopting a belt drive, the application effectively solves the problem of transmission efficiency between the driven wheels, ensures the effective transmission of power during the operation of the pesticide spraying machine, and improves the overall performance and reliability of the equipment.

[0040] The implementation of the belt drive can be various, such as using high-strength rubber belts or belts with wear-resistant coatings to adapt to different working environments and load requirements. Further, the belt tensioning device can adopt an automatic tensioner or a manual tensioner to ensure the optimal tension of the belt under different working conditions. In addition, the belt drive system can be equipped with a protective cover to prevent external debris from entering the transmission system, increasing the safety and reliability of the system.

[0041] By adopting a belt drive, the application can significantly improve the transmission efficiency and stability between the driven wheels, reduce the friction and wear of mechanical components, prolong the service life of the equipment, and reduce the maintenance cost. Compared with the prior art, the application provides a more efficient and reliable transmission scheme, ensuring the power transmission of the pesticide spraying machine during operation, and improving the overall performance and reliability of the equipment.

[0042] In addition to the above, the application further proposes that the external driving force is provided by a tractor engine.

[0043] By adopting a tractor engine as the external driving force, a stable and powerful power source can be provided for the automatic pesticide spraying machine. The tractor engine usually has high power and reliability, which is suitable for long-time and large-area pesticide spraying operations. Adopting a tractor engine can ensure that components such as the plunger pump 3 and the pipe reel 4 obtain sufficient power during operation, thereby improving the working efficiency and automation level of the automatic pesticide spraying machine.

[0044] The tractor engine can be connected to the driven wheel one 10 of the sprayer through a belt drive or a direct connection to achieve power transmission. As a preferred embodiment, a clutch can be provided between the tractor engine and the driven wheel one 10 for controlling the transmission of power, thereby achieving independent control of the piston pump 3 and the pipe reel 4. In addition, the output power of the tractor engine can be adjusted according to actual needs to adapt to different working conditions. In order to improve the flexibility and adaptability of the system, a gearbox can also be considered between the tractor engine and the sprayer to adjust the working speed of the sprayer under different working conditions.

[0045] The automated sprayer powered by a tractor engine can significantly improve the efficiency and automation of spraying operations. Compared with the prior art, the present application solves the problem of insufficient power of existing automated sprayers by introducing a tractor engine, ensuring that key components such as the piston pump 3 and the pipe reel 4 receive sufficient power support during operation, thereby improving the overall efficiency and reliability of the equipment. Therefore, the present application has significant advantages in improving spraying efficiency, reducing manual operation, and reducing equipment failure rate.

[0046] In embodiment seven, based on embodiment one, further, the reciprocating pipe dispenser 8 includes a reciprocating lead screw 16 and a sliding block 17 cooperating with the reciprocating lead screw 16, and the 360° pipe guide 9 is arranged on the sliding block 17. The 360° pipe guide 9 includes a rotating base 18, and a guide wheel set 19 is arranged on the top of the rotating base 18.

[0047] In specific manufacturing, the reciprocating lead screw 16 is fixed at both ends on the support of the pipe reel 4, and the rotating base 18 is fixed on the top of the sliding block 17.

[0048] The reciprocating lead screw 16 in the reciprocating pipe dispenser 8 cooperates with the sliding block 17 to achieve orderly pipe arrangement of the hose 7, avoiding entanglement and knotting of the hose 7. The 360° pipe guide 9 is arranged on the sliding block 17 and includes a rotating base 18 and a guide wheel set 19, which can achieve 360-degree turning and guiding of the hose 7 during pulling and paying out, preventing the hose 7 from being worn or cut. Through the cooperation of these technical features, the problem of time-consuming and laborious entanglement and knotting of the hose 7 during storage and paying out is solved.

[0049] The reciprocating lead screw 16 of the reciprocating pipe dispenser 8 can be made of high-strength material to ensure its durability during long-term use. The sliding block 17 can cooperate with the lead screw through a ball bearing to reduce friction and improve the smoothness of pipe arrangement. The rotating base 18 of the 360° pipe guide 9 can be provided with multiple guide wheels to further reduce the friction and wear of the hose 7. The guide wheel set 19 can be made of wear-resistant material to prolong the service life.

[0050] By adopting the reciprocating pipe arranging device 8 and the 360° pipe guiding device 9, the application can effectively solve the problem that the hose 7 is easy to be wound and knotted when being stored and unwound, improve the working efficiency and automation degree of the pesticide spraying machine, and reduce the labor intensity and time consumption of the operator. Compared with the prior art, the application significantly improves the service life and working reliability of the hose 7 through the innovative pipe arranging and guiding structure.

[0051] In the eighth embodiment, on the basis of the first embodiment, further, the application also proposes that the spray head support 5 adopts a folding spray head support.

[0052] The folding spray head support can be folded in the non-use state, reducing the occupied space and facilitating storage and transportation. Through this design, the spray head support 5 can be unfolded when in use to provide sufficient spraying range, and can be folded when not in use to solve the problem of inconvenient storage and carrying.

[0053] The implementation mode of the folding spray head support can include the following: specifically, a hinge connection mode can be adopted to enable the parts of the spray head support 5 to be folded and unfolded through the hinge; further, a locking device can be arranged at the hinge to ensure that the spray head support 5 is stably unfolded when in use; as a preferred implementation mode, a sliding rail structure can be adopted to make the folding and unfolding of the spray head support 5 more smooth. In addition, an automatic folding or unfolding function can be realized through a spring auxiliary mechanism to improve the convenience of operation. The material of the spray head support 5 can be selected from lightweight high-strength metals or composite materials to reduce the weight and ensure the service life.

[0054] Therefore, the application solves the problem of difficult storage of the spray head support 5 in the non-use state in the prior art through the design of the folding spray head support. Compared with the prior art, this design can significantly reduce the occupied space of the spray head support 5, facilitating the operation of the user during transportation and storage. At the same time, the folding design also improves the use flexibility of the spray head support 5, meets the needs in different scenarios, and thus improves the overall use experience and efficiency of the spraying machine.
