Description

Technical Field

[0001] This utility model relates to the field of agricultural and forestry machinery technology, and in particular to a spraying mechanism and a spraying robot. Background Technology

[0002] Spraying robots typically use tracked locomotives as their mobile chassis, primarily functioning to carry and transport pesticide application equipment for spraying operations in muddy terrain environments such as orchards. However, tracked locomotives suffer from high energy consumption; if electrically driven, their range is often insufficient to meet actual operational demands, resulting in limited operational flexibility. Furthermore, the application system requires a pesticide filtration system to prevent nozzle clogging, but filters typically occupy installation space within the pesticide tank. More significantly, because filters are usually located in concealed positions between the pesticide tank and the spraying components, cleaning and maintenance are quite challenging.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] like Figure 1 and Figure 2 As shown, the spraying mechanism 10 provided in this embodiment of the present invention includes: a pneumatic conveying component 11, a spraying component 12, a medicine tank 13, and a base 14; the pneumatic conveying component 11 is installed at the end of the base 14, and the medicine tank 13 is installed on the base 14; the spraying component 12 is located between the pneumatic conveying component 11 and the medicine tank 13, and the spraying component 12 and the medicine tank 13 are in fluid communication; the base 14 is used for detachable connection with the walking mechanism 20.

[0023] Specifically, the base 14 is equipped with clips or bolts to allow it to be detachably connected to the track vehicle, tracked vehicle, or wheeled chassis of the travel mechanism 20, thereby improving the flexibility of the spraying mechanism 10. The spraying assembly 12 can draw in the pesticide solution from the pesticide tank 13 and spray it into the air path of the air delivery assembly 11. The air delivery assembly 11 then blows the pesticide, thereby expanding the spraying range and improving the application efficiency.

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in this embodiment of the present invention, the medicine tank 13 and the spraying assembly 12 are in fluid communication via the filter 121, and the filter 121 is detachably connected to the bottom of the air delivery assembly 11.

[0025] The medicine tank 13 is connected to the spraying assembly 12 via a pipeline, and a filter 121 is installed in this pipeline. The filter 121 filters particulate impurities in the medicine solution, preventing them from clogging the spraying assembly 12. The filter 121 is installed at the bottom of the pneumatic conveying assembly 11 by means of threads or snap-fit. On the one hand, the filter 121 does not take up space in the medicine tank 13, ensuring that the medicine tank 13 has a large medicine capacity; on the other hand, the filter 121 can be removed from below the pneumatic conveying assembly 11 for easy cleaning and maintenance.

[0026] See Figure 2 and Figure 3 The air conveying assembly 11 includes an air duct 112 and a fan 113. The fan 113 is installed inside the air duct 112, and the filter 121 is installed at the bottom of the air duct 112.

[0027] The fan 113 uses a motor to drive the impeller to rotate. The impeller is coaxial with the air duct 112, thereby achieving air delivery along the axial direction of the air duct 112. The filter 121 is located at the bottom outside of the air duct 112, which not only facilitates the maintenance of the filter 121, but also prevents the filter 121 from occupying the internal air passage of the air duct 112.

[0028] like Figure 3 and Figure 4 As shown, the spraying assembly 12 includes: a nozzle 122, a spray pipe 123, a chemical pump 124, and a motor 125; the motor 125 is connected to the chemical pump 124 in a driving connection, the inlet of the chemical pump 124 is in fluid communication with the chemical tank 13, and the outlet of the chemical pump 124 is in fluid communication with the spray pipe 123; a plurality of nozzles 122 are installed on the spray pipe 123.

[0029] The medicine pump 124 is driven by the motor 125. It draws the medicine liquid from the medicine tank 13 through the nozzle 123 and directs the medicine liquid to the nozzle 123, and then sprays it out through several nozzles 122.

[0030] In an optional embodiment, the motor 125 and the medicine pump 124 can be connected by gear or chain drive. A speed reducer can also be installed between the motor 125 and the medicine pump 124 to reduce speed and increase torque, thereby increasing the pumping pressure of the medicine pump 124.

[0031] See Figure 4 In an optional embodiment, the motor 125 is connected to the driving pulley, and the medicine pump 124 is connected to the driven pulley. The driving pulley and the driven pulley are connected by a drive belt 126. The diameter of the driving pulley is smaller than that of the driven pulley. Because the driven pulley rotates at a lower speed than the driving pulley, the driving torque of the driven pulley on the medicine pump 124 is increased, thereby increasing the output pressure of the medicine pump 124.

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the medicine pump 124 and the motor 125 are both installed between the air duct 112 and the medicine tank 13, so as to avoid the medicine pump 124 and the motor 125 obscuring the filter 121 and making the filter 121 difficult to maintain. In addition, the medicine pump 124 and the motor 125 can utilize the internal area of ​​the air duct 112 near the end of the medicine tank 13, thereby improving the structural compactness.

[0033] Furthermore, the nozzle 123 extends circumferentially along the air duct 112, and multiple nozzles 122 are spaced apart along the nozzle 123; the multiple nozzles 122 face the inside of the air duct 112, and all the multiple nozzles 122 are located on the air outlet side of the fan 113. The liquid medicine sprayed from the multiple nozzles 122 can be blown by the fan 113, so that the liquid medicine is sprayed out in an atomized state through the rear opening of the air duct 112.

[0034] See Figure 3 An air guide plate 111 is installed inside the air duct 112. The air guide plate 111 is located on the air outlet side of the fan 113, and the nozzle 122 is located on the outside of the air guide plate 111 in the direction of airflow.

[0035] The airflow blown by the blower 113 can flow along the air guide plate 111 and can diffuse radially relative to the air duct 112, so that the liquid mist can be fully diffused with the airflow to expand the application range.

[0036] like Figure 1 As shown, the spraying robot provided in this embodiment of the present invention includes the spraying mechanism 10 described in the above embodiments. The spraying robot has the technical effects of the spraying mechanism 10, which will not be repeated here.

[0037] In this embodiment of the utility model, with the base 14 connected to the walking mechanism 20, the air delivery component 11 faces the rear of the walking mechanism 20. The walking mechanism 20 can be configured as a railcar, tracked vehicle, or wheeled chassis, etc. The air delivery component 11 delivers air to the rear of the walking mechanism 20, and diffuses the sprayed liquid to the rear of the walking mechanism 20. As the walking mechanism 20 moves forward, efficient application of the pesticide can be achieved, and the walking mechanism 20 can be prevented from being contaminated with the pesticide, reducing the ineffective loss of the pesticide.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
