Description

Technical Field

[0001] The utility model relates to the technical field of agricultural automation equipment, in particular to a ground crop spraying robot. Background Art

[0002] Pesticide spraying is a crucial step in protecting crops from pests and diseases in agriculture. Currently, pesticide spraying relies primarily on manual knapsack sprayers or drones. Manual knapsack sprayers are labor-intensive to operate, inefficient, and can easily cause poisoning to applicators and environmental pollution. While drone spraying offers advantages such as high efficiency and time and labor savings, it also has some significant drawbacks:

[0003] For example, the purchase cost of drones is high, and the subsequent maintenance and use costs are also high, which is unaffordable for small-scale growers; the operation of drones requires professional flying skills and maintenance knowledge, and the technical requirements for operators are high, which increases the threshold for use; when drones spray pesticides, due to the high flight altitude, the pesticides are easy to drift, which not only affects the efficacy of the medicine, but may also cause pollution to the surrounding environment. Utility Model Content

[0004] The purpose of the present invention is to address the deficiencies in the above-mentioned prior art and to provide a ground crop spraying robot that can operate stably in a farmland environment, so as to reduce labor intensity and improve operation efficiency.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solution: a ground crop spraying robot, comprising a walking chassis that can move on the ground, a spraying mechanism installed on the walking chassis, and a lifting mechanism for driving the spraying mechanism to move up and down, the spraying mechanism comprising a medicine box for containing medicine, a water pump connected to the medicine box, a spray head connected to the water pump and installed on the lifting mechanism, and the number of the spray heads is multiple and they are respectively arranged to be inclined upward toward the outside.

[0006] Preferably, the lifting mechanism includes a scissor-type bracket provided on a walking chassis, and a cylinder for driving the scissor-type bracket to move.

[0007] More preferably, the scissor-type bracket includes a bottom plate, a top plate and two groups of movable parts connected to the bottom plate and the top plate, each group of movable parts includes two movable rods that are cross-arranged and hinged to each other. In the same group of movable parts, the top end of one of the movable rods is hinged to the top plate, and the bottom end is slidably connected to the track on the bottom plate through a roller; the bottom end of the other movable rod is hinged to the bottom plate, and the top end is slidably connected to the track on the top plate through a roller.

[0008] More preferably, a lower support rod is fixedly connected between one movable rod in the movable part and the corresponding movable rod in the other movable part, and an upper support rod is movably connected between the two corresponding movable rods, and the upper support rod can move along the movable rod, and the upper support rod and the lower support rod are respectively arranged on the upper and lower sides of the intersecting movable rod hinge point, and the cylinder is connected to the lower support rod and the upper support rod, and the cylinder can push or pull the upper support rod, thereby causing the movable part to fold to realize the lifting and lowering adjustment of the top plate.

[0009] More preferably, the top plate is installed with a four-way valve, the water pump is connected to the four-way valve through a pipeline, the number of the spray heads is three, and the four-way valve is connected to each spray head through a pipeline.

[0010] More preferably, a gas cylinder is installed on the walking chassis, the gas cylinder is connected to the gas cylinder through an air pipe, and a solenoid valve is provided on the air pipe.

[0011] More preferably, the walking chassis is equipped with four steering wheels, and each steering wheel is equipped with an independent steering wheel motor.

[0012] Compared with existing technologies, this new system significantly improves pesticide spraying efficiency by replacing manual backpack sprayers with automated spraying robots, reducing manpower requirements and making pesticide spraying faster and more efficient. The multiple spray heads design ensures more uniform pesticide spraying, reducing pesticide waste. Adjustable spray head heights allow for precise spraying tailored to different crops. Because the spray robot operates at a relatively low height, pesticide drift is effectively controlled, minimizing pollution to the surrounding environment and minimizing the impact on non-target crops.

[0022] In order to facilitate understanding by those skilled in the art, the present invention is further described below with reference to embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention.

[0023] It should be noted in advance that, in this utility model, unless otherwise expressly specified or limited, terms such as "installed," "connected," "connected," and "fixed" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integral connections. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances. Furthermore, in this utility model, unless otherwise expressly specified or limited, a first feature "above" or "below" a second feature may include direct contact between the first and second features, or may include contact between the first and second features not being in direct contact but through another feature between them.

[0024] like Figures 1 to 3 As shown, the ground crop spraying robot includes a walking chassis 1 that can move on the ground, a spraying mechanism installed on the walking chassis 1, and a lifting mechanism for driving the spraying mechanism to move up and down. The spraying mechanism includes a medicine box 2 for containing medicine, a water pump 3 connected to the medicine box 2, and a spray head 4 connected to the water pump 3 and installed on the lifting mechanism. There are multiple spray heads 4 and they are respectively arranged to be inclined upward toward the outside.

[0025] In the above structure, the lifting mechanism includes a scissor-type bracket provided on the traveling chassis 1, and a cylinder 15 for driving the scissor-type bracket to move. The scissor-type bracket includes a bottom plate 5, a top plate 6, and two sets of movable parts connected to the bottom plate 5 and the top plate 6. Each set of movable parts includes two movable rods 7 arranged crosswise and hinged to each other. In the same set of movable parts, the top end of one movable rod 7 is hinged to the top plate 6, and the bottom end is slidably connected to the track on the bottom plate 5 via rollers 8. The bottom end of the other movable rod 7 is hinged to the bottom plate 5, and the top end is slidably connected to the track on the top plate 6 via rollers 8.

[0026] A lower support rod 9 is fixedly connected between one movable rod 7 in the movable part and the corresponding movable rod 7 in the other movable part, and an upper support rod 10 is also movably connected between the two corresponding movable rods 7. The upper support rod 10 can move along the movable rod 7. The upper support rod 10 and the lower support rod 9 are respectively arranged on the upper and lower sides of the hinge point of the intersecting movable rod 7. The cylinder 15 is connected to the lower support rod 9 and the upper support rod 10. The cylinder 15 can push or pull the upper support rod 10, thereby causing the movable part to fold to achieve the lifting and lowering adjustment of the top plate 6. The folding design of the movable part makes the lifting and lowering of the top plate 6 more stable, while reducing friction and wear during the lifting process, and extending the service life of the equipment. The ingenious connection method between the upper support rod 10 and the lower support rod 9 ensures the stability and reliability when the cylinder 15 is driven, while simplifying the structure of the lifting mechanism, making it easy to maintain and operate.

[0027] In addition, a four-way valve 11 is mounted on the top plate 6. The water pump 3 is connected to the valve via a rubber hose. There are three spray heads 4, each connected to a separate pipe. The design of the four-way valve 11 allows the water pump 3 to supply water to all three spray heads 4 simultaneously, independently controlling each spray head through the pipes. This ensures precise drug distribution and efficient spraying. The three spray heads provide wider coverage and improved spray uniformity, and the upward-angled design of the outer spray heads helps ensure better drug adhesion to the crops.

[0028] A gas cylinder 12 is mounted on the chassis 1. This gas cylinder 12 is connected to a cylinder 15 via an air pipe equipped with a solenoid valve 13. This allows the movement of the cylinder 15 to be remotely controlled, improving operational convenience and safety. The chassis 1 is also equipped with four steering wheels 14, each equipped with an independent steering motor. These four independently controlled steering wheels 14 provide enhanced maneuverability and controllability, enabling the spraying robot to maneuver flexibly in complex farmland environments.

[0029] In this embodiment, a power storage device can be installed on the traveling chassis 1 to connect the steering wheel motor, solenoid valve 13, and water pump 3, and configure a control system for easy operation. This allows the spraying robot to operate independently without an external power source, enhancing its flexibility and adaptability. The control system makes operation more intelligent and integrated, improving the accuracy and efficiency of the operation.

[0030] The workflow of the ground crop spraying robot provided in the above embodiment is as follows:

[0031] First, the operator uses the control system to move the spraying robot to the farmland operation area. The robot's four independently controlled steering wheels 14 enable flexible movement within the field. Based on the height of the crops, the operator adjusts the cylinder 15 through the control system, which in turn drives the movable parts of the scissor-type bracket, raising and lowering the spray head 4 on the top plate 6 to the appropriate height. The operator can use the control system to set the spray parameters of the spray head 4, including spray pressure and flow rate, to suit the spraying needs of different crops and pesticides. The operator then activates the water pump 3, which evenly distributes water or liquid medicine to each spray head 4 via the four-way valve 11. The spray heads 4 begin spraying pesticides. Under the operator's control, the spraying robot begins to move along the planned path within the field, while the spray heads 4 evenly spray pesticides to control crop diseases and pests.

[0032] The ground crop spraying robot of the utility model can adapt to crops of different heights and carry out precise spraying through the intelligent lifting mechanism and multiple spray heads on its walking chassis, thereby improving work efficiency, reducing labor intensity, reducing pesticide drift and waste, and improving pesticide utilization rate. At the same time, it is easy to operate, has strong adaptability, is environmentally friendly, and improves the safety and economy of agricultural spraying operations.

[0033] In order to make it easier for ordinary technicians in this field to understand the improvements of the present invention over the prior art, some drawings and descriptions of the present invention have been simplified, and the above-mentioned embodiments are better implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
