Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a multi-functional operation vehicle for the prevention and control of vegetable diseases and pests. Background Technology

[0002] Vegetable cultivation is an important part of agricultural production, and pest and disease control is a key aspect of ensuring yield and quality during the vegetable growth process. Chemical pesticide spraying is currently one of the most widely used and effective methods for pest and disease control; therefore, various types of spraying equipment are widely used in agricultural production.

[0003] Existing vegetable spraying equipment, especially small or hand-push sprayers, usually has a relatively simple structure. Most of them have one or more nozzles fixedly installed on the vehicle body, and move between the ridges by manual pushing or self-propelled means, spraying the vegetables with pesticide solution from a fixed angle and height.

[0004] However, this fixed-structure spraying method has inherent drawbacks. Firstly, vegetables, as vertically growing crops, have leaves and stems that create complex shading relationships. Spraying from a fixed angle only from the top or side easily creates blind spots on the undersides of leaves and the lower parts of the plant. Furthermore, many pests and pathogens often hide on the undersides of leaves, in the lower lateral leaves, and near the ground in the root zone, making it impossible to completely eliminate pests and diseases. More importantly, the height and canopy width of vegetables change significantly with their growth cycle, and different varieties and planting densities have different requirements for the spraying range. Once the spraying height and coverage width of existing spray trucks are determined, they are difficult to change. Their structure and function are singular, lacking adaptability and unable to flexibly match changing agronomic needs, which severely restricts their operational efficiency and pest control effectiveness.

[0005] Therefore, this utility model proposes a multi-functional operation vehicle for the prevention and control of vegetable diseases and pests to address the shortcomings of existing technologies. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a multi-functional operation vehicle for vegetable pest and disease control, which aims to improve the problems of existing multi-functional operation vehicles for vegetable pest and disease control, such as blind spots in spray coverage, single function, and fixed spray height and width that cannot adapt to vegetables at different growth stages and planting patterns, resulting in poor control effect and poor applicability.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a multi-functional vegetable pest and disease control vehicle, comprising: a main frame, wheels, a storage tank, and a base; and a dynamic spraying structure and a conduit connecting the storage tank and the dynamic spraying structure;

[0008] The dynamic spray structure includes a lifter, a lifting platform, a rotating shaft, a reciprocating swing assembly, and a drive assembly.

[0009] Furthermore, the lifting device is vertically installed inside the base, the bottom of the lifting platform is fixedly connected to the drive end of the lifting device, and the rotating shaft is rotatably connected to the lifting platform; the reciprocating swing assembly includes an extension plate and a support plate, one end of the extension plate is rotatably connected to the rotating shaft, the support plate is slidably connected to the extension plate, and a nozzle is fixedly connected to the top of the support plate, the nozzle being connected to the storage tank via the conduit; the drive assembly includes an electric actuator and a linkage assembly consisting of a drive rod and a linkage plate, the electric actuator is fixedly connected to the lifting platform, the drive rod is snapped onto the support plate, and the other end of the linkage plate is slidably sleeved on the fixed rod.

[0010] Preferably, a spring is also connected between the support plate and the extension plate; the extension plate has multiple adjustment holes, and the support plate is provided with a buckle structure that cooperates with the adjustment holes.

[0011] Preferably, a limiting plate is also fixedly connected to the lifting platform, the limiting plate being used to limit the range of rotation of the extension plate around the rotating shaft.

[0012] Preferably, the bottom of the lifting platform is also fixedly connected to a plurality of support rods, the bottom ends of which are retractably supported on the base.

[0013] Preferably, a fixed rod is also fixedly connected to the lifting platform, and the linkage plate is sleeved on the fixed rod and slides along its length.

[0014] Preferably, side plates are fixedly connected to both sides of the base, and nozzles are fixedly connected to the side plates. The nozzles on the side plates are connected to the storage tank via the conduit.

[0015] Preferably, based on the above, a rotating disk is rotatably connected to the bottom of the base, a nozzle is fixedly connected to the rotating disk, and the nozzle on the rotating disk is connected to the storage tank via the conduit.

[0016] Preferably, a push handle is also fixedly connected to the main frame; the top of the storage tank is detachably sealed by a lid.

[0017] This utility model has the following beneficial effects:

[0018] 1. In this utility model, by setting up a dynamic spraying structure that can be raised, lowered and reciprocated, and working in coordination with the fixed nozzles on the side panels and bottom rotating disc of the vehicle body, the problem of the existing spraying equipment having a single spraying angle, having spraying blind spots, and being unable to cover the back, sides and roots of vegetable leaves is solved. This achieves a comprehensive, three-dimensional, and dead-angle-free spraying effect on vegetable plants, significantly improving the thoroughness of pest and disease control.

[0019] 2. In this utility model, by setting up a lifting device to drive the vertical movement of the lifting platform, and by using a spring-loaded sliding engagement between the support plate and the extension plate with multi-level adjustment holes, the problem of the existing spray truck having a fixed structure and function, being unable to adapt to vegetables with different growth cycles and different planting row spacings, and having a single applicable scenario is solved. The technical effect of flexibly adjusting both the spraying height and spraying width is achieved, enabling the equipment to accurately match diverse agronomic requirements and greatly enhancing the applicability and operational flexibility of the equipment.

[0020] 3. This utility model solves the problems of swaying, wobbling, and uncontrollable swing angle that may occur in traditional linkage transmission structures during high-speed reciprocating motion by setting a fixed rod on the lifting platform to slide and guide the linkage plate in the linkage assembly, and setting a limiting plate to limit the rotation range of the extension plate. This achieves the technical effect of improving the operational stability and motion trajectory accuracy of the dynamic spraying structure, ensuring that the liquid can be sprayed evenly and stably on the target area, and improving the spraying quality.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figures 1-3 This utility model provides a multi-functional vegetable pest and disease control vehicle, which aims to solve the problems of existing vegetable spraying equipment having a single spraying angle, incomplete coverage, and fixed structure and function, making it unable to adapt to changing planting conditions.

[0031] like Figure 1 and Figure 2 As shown, the multi-functional vegetable pest and disease control vehicle includes a main frame 1, a pusher 2 fixedly connected to the rear of the main frame 1, multiple wheels 5 installed at the bottom of the main frame 1, a storage tank 3 installed on the main frame 1, the top of the storage tank 3 being detachably sealed by a cover 4, and a base 9 fixedly connected to the bottom of the main frame 1, which provides a stable installation platform for the entire spraying structure.

[0032] The spray truck further includes a dynamic spray structure. The core components of the dynamic spray structure are all mounted on the base 9. Specifically, a lifter 22 is vertically arranged on the inner side of the base 9. The drive end of the lifter 22 extends upward through the base 9 and is fixedly connected to the bottom of the lifting platform 20. Multiple support rods 21 are also fixedly connected to the bottom of the lifting platform 20. The bottom ends of the support rods 21 are telescopically supported on the base 9 to enhance the structural stability of the lifting platform 20 during the lifting process.

[0033] The lifting platform 20 integrates a reciprocating swing assembly and a drive assembly. A rotating shaft 19 is rotatably connected to the lifting platform 20, which serves as the rotation center of the reciprocating swing assembly. The reciprocating swing assembly includes an extension plate 14 and a support plate 12. One end of the extension plate 14 is rotatably connected to the rotating shaft 19, and the support plate 12 is slidably connected to the extension plate 14. A nozzle 11 is fixedly connected to the top of the support plate 12. One end of the conduit 8 is connected to the nozzle 11, and the other end is connected to the storage tank 3 for conveying liquid medicine. The drive assembly includes an electric push rod 7 and a linkage assembly consisting of a drive rod 15 and a linkage plate 17. The electric push rod 7 is fixedly connected to the lifting platform 20, and the drive rod 15 is snapped onto the support plate (12). The other end of the linkage plate (17) is slidably sleeved on the fixed rod (13). The setting of this drive assembly accurately converts the linear reciprocating motion output by the electric push rod 7 into the reciprocating swing of the support plate 12 around the rotating shaft 19.

[0034] The length adjustment function of the reciprocating swing assembly is achieved by the extension plate 14, the support plate 12, and the spring 16 working together. The extension plate 14 has multiple adjustment holes, and the support plate 12 has a snap-fit ​​structure that cooperates with the adjustment holes. The spring 16 is connected between the support plate 12 and the extension plate 14. In the natural state, the elastic force of the spring 16 causes the snap-fit ​​structure to snap into one of the adjustment holes, thereby locking the relative position of the support plate 12 and the extension plate 14. When it is necessary to adjust the spray range, the external force pulls the drive rod 15, which can drive the support plate 12 to compress the spring 16, causing the snap-fit ​​structure to disengage from the adjustment hole. At this time, the support plate 12 can be slid along the length direction of the extension plate 14 to change the overlap length between the two. After selecting a new position, the external force is released, the spring 16 returns to its original position, and the snap-fit ​​structure is re-clamped and fixed in the new adjustment hole position. This structure allows the total length of the spray arm to be adjusted in stages.

[0035] Meanwhile, to ensure the stability of the reciprocating oscillating assembly during high-speed movement, multiple auxiliary limiting and guiding components are fixedly connected to the lifting platform 20. A limiting plate 18 is fixedly connected to the lifting platform 20. The limiting plate 18 is symmetrically arranged on both sides of the rotating end of the extension plate 14 to precisely limit the starting and ending angles of the extension plate 14's rotation around the rotating shaft 19, ensuring that the angle range of the fan-shaped spray is constant. An electric push rod 7 is fixedly connected to the lifting platform 20. The direction of movement of the electric push rod 7 is set. The linkage plate 17 in the linkage assembly is sleeved on the fixed rod 13 and can slide in its length direction. This structure provides a stable motion guide for the linkage plate 17, preventing it from lateral swaying when transmitting driving force, thereby ensuring that the driving force is smoothly and efficiently transmitted to the support plate 12.

[0036] As a preferred implementation method, in order to achieve all-round three-dimensional spraying of vegetables, the spray truck also integrates a fixed spraying system, please refer to... Figure 1 and Figure 2The base 9 has side plates 6 fixedly connected to both sides, and each side plate 6 has at least one nozzle 11 fixedly connected to it. These nozzles 11 are also connected to the storage tank 3 via the conduit 8. Their spray direction is towards the inside of the vehicle body and slightly upward, mainly responsible for spraying the side leaves and back of the leaves of vegetables.

[0037] As a further optimization of the above-mentioned fixed spraying system, a rotating disk 10 is also rotatably connected to the bottom of the base 9. At least one nozzle 11 is also fixedly connected to the rotating disk 10, and it is also connected to the storage tank 3 via the conduit 8. The rotating disk 10 can be driven to rotate by an independent micro motor. The nozzle 11 on it is mainly responsible for spraying the bottom area of ​​the root and stem of the vegetables. Through the rotational movement, the roots can be covered in a surrounding manner.

[0038] Working principle: During operation, the staff pushes the main frame 1 with the pusher 2, and the rotation of the wheels 5 enables the whole vehicle to move between the ridges. The liquid medicine pre-filled in the storage tank 3 through the cover 4 is delivered to each nozzle 11 through the conduit 8. At this time, the nozzles 11 installed on the side plates 6 on both sides of the base 9 and the nozzles 11 on the bottom rotating plate 10 can be started first to carry out basic spraying on the side leaves, the back of the leaves and the root parts of the vegetables, to achieve preliminary three-dimensional coverage.

[0039] When it is necessary to spray a large area of ​​the upper leaves of vegetables efficiently, the electric actuator 7 installed on the lifting platform 20 is activated. The output end of the electric actuator 7 performs reciprocating linear motion. Through the linkage assembly formed by the rotating drive rod 15 and the linkage plate 17, the linear motion is converted into driving force and applied to the support plate 12. Since one end of the extension plate 14 is rotatably connected to the rotating shaft 19, the driving force causes the support plate 12 and the extension plate 14 to reciprocate fan-shaped swing around the rotating shaft 19. The nozzle 11 installed at the top of the support plate 12 also performs fan-shaped scanning spraying. During the entire swinging process, the linkage plate 17 is always sleeved on the fixed rod 13 and slides along it, ensuring the smoothness and accuracy of the transmission process. The swing angle of the extension plate 14 is strictly limited by the limiting plate 18, ensuring that the boundary of the spraying range is clear.

[0040] The multi-functional adaptability of this utility model is reflected in its adjustment mechanism. When dealing with vegetables at different growth stages, operating the lifting device 22 can drive the lifting platform 20 together with the entire set of dynamic spraying structures above it to achieve vertical lifting and lowering of the whole structure. The support rod 21 ensures the stability of the lifting and lowering process, thereby accurately matching the crop height. When dealing with vegetables with different planting row spacings, the support plate 12 can be pulled by external force to compress the spring 16, causing the buckle structure on it to disengage from the adjustment hole of the extension plate 14. After adjusting the overlap length of the two along the length direction of the extension plate 14, the spring force of the spring 16 will cause the buckle structure to relock in the new position. This process changes the radius of the reciprocating swing, thereby realizing the flexible adjustment of the spraying width. Through the synergistic effect of the above components, this utility model solves the problems of blind spots, uneven coverage, and inability to adapt to changing planting conditions in the prior art.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
