Description

Technical Field

[0001] This utility model relates to the field of sprayer technology, specifically a spraying protection device for an agricultural self-propelled sprayer. Background Technology

[0002] Agricultural self-propelled sprayers, also known as spray trucks, are important plant protection equipment in agricultural production. They mainly consist of a frame, self-propelled mechanism, pesticide tank, spraying system, and control equipment. They are highly efficient and widely used. In field crops, they are suitable for common crops such as soybeans, wheat, corn, rice, and potatoes. They can be used for pre-planting soil treatment, seedling weed control, and pest and disease control.

[0003] Currently, most existing self-propelled sprayers have relatively simple functions, mainly used for spraying operations, and lack necessary protective devices. In practical applications, when it is necessary to spray crops in a specific area, and crops in adjacent areas have adverse reactions to the pesticide, sprayers without protective devices are very likely to cause pesticide drift, resulting in reduced yields of adjacent crops. Secondly, the sprayed pesticide can also enter the self-propelled mechanism of the sprayer, easily causing internal corrosion and other problems. Therefore, it is urgent to design a spraying protection device for agricultural self-propelled sprayers to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a spraying protection device for a self-propelled agricultural sprayer to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A spraying protection device for a self-propelled agricultural sprayer includes a sprayer unit comprising a frame, a control box, a pesticide tank, a spraying system, and a self-propelled mechanism. A protective component is fixedly installed between one side of the self-propelled mechanism and the inner top wall of the frame. The protective component includes a protective top plate fixedly installed on the inner top wall of the frame and an L-shaped side guard plate fixedly installed on the outer side wall of one side of the self-propelled mechanism. Both ends of the L-shaped side guard plate are provided with L-shaped telescopic grooves, and telescopic plates are inserted into the inner walls of the telescopic grooves. The top of the L-shaped side guard plate is provided with a telescopic mechanism for adjusting the position of the telescopic plates.

[0007] Furthermore, the control box and the medicine tank are both fixedly installed on the top of the frame, and the spraying system is fixedly installed between the two L-shaped side guards. The spraying system is connected to the medicine tank, and the self-propelled mechanism is fixedly installed at both ends of the bottom of the frame.

[0008] Furthermore, the telescopic mechanism includes a cover plate fixedly installed on the top of the L-shaped side guard plate, and L-shaped racks are slidably arranged on both inner walls of the cover plate. A drive gear is rotatably connected to the middle of the inner wall of the cover plate. The drive gear meshes with the two L-shaped racks. A forward and reverse motor for driving the drive gear to rotate is fixedly installed on the top of the cover plate. Guide grooves communicating with the telescopic groove are opened on both sides of the top of the L-shaped side guard plate. A guide block inserted into the guide groove is fixed at one end of the top of the telescopic plate. The guide block is fixedly connected to the L-shaped rack.

[0009] Furthermore, the inner walls on both sides of the cover plate are provided with sliding grooves, and one side of each of the two L-shaped racks is fixedly installed with a sliding seat that is slidably disposed in the sliding groove.

[0010] Furthermore, both ends of the top of the protective top plate and the top of the L-shaped side guard plate are fixedly installed with telescopic components, and the telescopic components are corrugated elastic expansion joints.

[0011] Furthermore, inclined top plates are fixedly installed on both sides of the protective top plate.

[0012] Furthermore, the control box is equipped with a controller and a battery, and the controller, battery, self-propelled mechanism, spray system and forward and reverse motors are electrically connected.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, a protective assembly is formed by a protective top plate, an L-shaped side guard plate, and a telescopic plate whose position can be adjusted by a telescopic mechanism. This assembly can form a relatively enclosed spraying space. This design can effectively prevent the sprayed pesticide from spreading to adjacent areas, avoid adverse effects on adjacent crops due to pesticide drift, and reduce the risk of crop yield reduction. It is especially suitable for scenarios where precise spraying of pesticides is required in specific areas, and adjacent crops are sensitive to the pesticide.

[0015] In this invention, the protective component effectively isolates the spraying system from the self-propelled mechanism, reducing the possibility of the sprayed drug entering the self-propelled mechanism. This reduces the probability of malfunctions caused by drug corrosion inside the self-propelled mechanism, helps extend the overall service life of the sprayer, and reduces equipment maintenance costs.

[0016] In this invention, the telescopic mechanism drives the drive gear to rotate via a forward and reverse motor, which in turn causes the L-shaped rack to slide the telescopic plate within the telescopic groove. The extension length of the telescopic plate can be flexibly adjusted according to the actual needs of the spraying operation, thereby changing the protection range. At the same time, the telescopic components at the top of the protective top plate and the top of the L-shaped side guard plate, as well as the inclined top plates on both sides of the protective top plate, further enhance the adaptability of the device to different operating environments and enable it to better cope with complex farmland conditions.

[0024] 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.

[0025] Please see Figures 1-6In this embodiment of the present invention, a spraying protection device for a self-propelled agricultural sprayer includes a sprayer device 1. The sprayer device 1 includes a frame 11, a control box 12, a pesticide tank 13, a spraying system 14, and a self-propelled mechanism 15. The control box 12 and the pesticide tank 13 are both fixedly installed on the top of the frame 11. The spraying system 14 is fixedly installed between two L-shaped side guard plates 22 and is connected to the pesticide tank 13. The self-propelled mechanism 15 is fixedly installed at both ends of the bottom of the frame 11. A protective component 2 is fixedly installed between one side of the self-propelled mechanism 15 and the inner top wall of the frame 11. The protective component 2 includes a protective top plate 2 fixedly installed on the inner top wall of the frame 11. 1. An L-shaped side guard plate 22 is fixedly installed on the outer wall of one side of the self-propelled mechanism 15. Both ends of the L-shaped side guard plate 22 have L-shaped telescopic grooves 26, and telescopic plates 23 are inserted into the inner walls of the telescopic grooves 26. The top of each L-shaped side guard plate 22 is provided with a telescopic mechanism 3 for adjusting the position of the telescopic plates 23. The telescopic mechanism 3 includes a cover plate 32 fixedly installed on the top of the L-shaped side guard plate 22, and L-shaped racks 36 are slidably arranged on the inner walls of both sides of the cover plate 32. A drive gear 34 is rotatably connected to the middle of the inner wall of the cover plate 32. The drive gear 34 meshes with the two L-shaped racks 36, and a positive gear for driving the drive gear 34 to rotate is fixedly installed on the top of the cover plate 32. The top two sides of the L-shaped side guard plate 22 are provided with guide grooves 31 that communicate with the telescopic groove 26. A guide block 35 is fixed to one end of the top of the telescopic plate 23 and inserted into the guide groove 31. The guide block 35 is fixedly connected to the L-shaped rack 36. Sliding grooves 38 are provided on both inner walls of the cover plate 32. A sliding seat 37 is fixedly installed on one side of each of the two L-shaped racks 36 and slidably disposed within the sliding groove 38. The control box 12 contains a controller and a battery. The controller, battery, self-propelled mechanism 15, sprinkler system 14, and forward / reverse motor 33 are electrically connected. The protective top plate 21, L-shaped side guard plate 22, and telescopic plate 23 together form the protective assembly 2. It can form a relatively closed spraying space, effectively blocking the spread of sprayed pesticides to adjacent areas, avoiding adverse effects on adjacent crops due to pesticide drift, and reducing the risk of crop yield reduction. At the same time, the protective component 2 effectively isolates the spraying system 14 from the self-propelled mechanism 15, preventing pesticides from entering the interior of the self-propelled mechanism 15. Furthermore, the forward and reverse motor 33 in the telescopic mechanism 3 can drive the drive gear 34 to rotate, drive the L-shaped rack 36 to move within the cover plate 32, and drive the telescopic plate 23 to extend and retract within the telescopic grooves 26 at both ends of the L-shaped side guard plate 22. Thus, the extension length of the telescopic plate 23 can be flexibly adjusted according to the actual needs of the spraying operation, thereby changing the protection range.

[0026] Specifically, both ends of the top of the protective top plate 21 and the top of the L-shaped side guard plate 22 are fixedly installed with telescopic components 25, and the telescopic components 25 are corrugated elastic expansion joints.

[0027] Specifically, inclined top plates 24 are fixedly installed on both sides of the protective top plate 21. The cooperation between the inclined top plates 24 and the telescopic components 25 further enhances the adaptability of the device in different operating environments and can better cope with complex farmland conditions.

[0028] The working principle of this utility model is as follows: Before the operation begins, the controller in the control box 12 presets relevant parameters, and the battery powers the self-propelled mechanism 15, the forward and reverse motor 33, the spraying system 14 and other components to ensure that each device is in a ready-to-work state. According to the actual situation of the area to be sprayed, if the protection range needs to be adjusted, the controller starts the forward and reverse motor 33. The forward and reverse motor 33 drives the drive gear 34 to rotate. Since the drive gear 34 meshes with the two L-shaped racks 36, it will drive the L-shaped racks 36 to move in the cover plate 32. At this time, the slide block 37 on one side of the L-shaped rack 36 slides along the slide groove 38 on the inner wall of the cover plate 32. When the L-shaped rack 36 moves, the guide block 35 slides along the guide groove 31 on the top of the L-shaped side guard plate 22, thereby driving the telescopic plate 23 to extend or retract in the telescopic grooves 26 at both ends of the L-shaped side guard plate 22 until the required protection range is reached. Then the forward and reverse motor 33 stops working. At the same time, the inclined top plate 24 cooperates with the protective top plate 21 and the L-shaped side guard plate 22 to form a complete protective space.

[0029] Next, the controller starts the self-propelled mechanism 15, which drives the sprayer equipment 1 to move as a whole. At the same time, the controller controls the spraying system 14 to start working. The liquid pesticide in the tank 13 is sprayed onto the target crops through the spraying system 14. During the spraying process, the protective space formed by the protective component 2 effectively blocks the liquid pesticide from drifting, avoiding the impact on crops in adjacent areas, and at the same time protecting the self-propelled mechanism 15 from the corrosion of the liquid pesticide.

[0030] After the operation is completed, the controller shuts down the sprinkler system 14 and the self-propelled mechanism 15 in sequence, and starts the forward and reverse motor 33 to reverse so that the telescopic plate 23 returns to the initial position.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
