Description

Technical Field

[0001] This invention relates to the field of pesticide spraying technology, specifically to an agricultural robot capable of rapidly and accurately spraying pesticides. Background Technology

[0002] The emergence and development of modern agriculture has significantly increased agricultural labor productivity and land productivity, leading to major changes in agricultural production and the rural landscape.

[0003] With the continuous development of industrialization, a large number of surplus rural laborers have migrated to other areas. In addition, my country is facing an increasingly serious aging population problem, leading to a shortage of agricultural labor. As agricultural modernization progresses, agricultural spraying robots have gradually emerged.

[0004] For example, a multifunctional intelligent agricultural robot disclosed in Chinese patent CN113575107A is equipped with a vehicle body, a walking mechanism, a weeding mechanism, a soil testing mechanism, and a pesticide sprayer. When the vehicle body walks in the vegetable field, the weeding mechanism can cut weeds. When soil testing is required, information can be obtained through the soil testing mechanism. In addition, pesticides can be sprayed through the pesticide sprayer.

[0005] However, the pesticide spraying nozzles mounted on this agricultural robot are at a fixed height, making it impossible to adjust the spraying height according to the height of the crops.

[0006] Therefore, we urgently need to provide an agricultural robot that can spray pesticides quickly and accurately. Summary of the Invention

[0007] The purpose of this invention is to provide an agricultural robot capable of rapidly and accurately spraying pesticides, in order to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: an agricultural robot capable of rapidly and accurately spraying pesticides, comprising a vehicle body and a liquid storage tank, wherein the liquid storage tank is fixedly connected to the upper left end of the vehicle body, a lid is connected to the upper end of the liquid storage tank, and an inlet hopper is fixedly connected to the upper left end of the lid; a spraying mechanism is connected to the upper and lower ends of the vehicle body, the spraying mechanism comprising a spraying unit, a cleaning unit, and a cutting unit, wherein the spraying unit is disposed at the upper and lower ends of the vehicle body, the cleaning unit is disposed at the outer end of the liquid storage tank, and the cutting unit is disposed at the lower end of the vehicle body.

[0009] The spraying unit includes a telescopic component, a circular tube, a nozzle, a water pump, and a water pipe. The telescopic component is fixedly connected to the middle position of the front and rear ends of the lower side of the vehicle body. The circular tube is fixedly connected to the upper end of the output shaft of the telescopic component. The nozzle is fixedly connected to the end of the circular tube away from the liquid storage tank. The water pump is fixedly connected to the right end of the liquid storage tank. The water pipe is fixedly connected to the right end of the water pump.

[0010] Preferably, the end of the water pipe away from the water pump is fixedly connected to the middle of the end of the round pipe near the water pump, so that by starting the water pump, the pesticide in the storage tank can be drawn into the water pipe, and then enters the round pipe through the water pipe and is sprayed out through the nozzle onto the crops at both ends of the vehicle body.

[0011] Preferably, the cleaning unit includes a cover, a first motor, a stirring shaft, a connecting block, a spring, a plug rod, and a connecting frame. The cover is connected to the upper outer side of the liquid inlet hopper. The first motor is fixedly connected to the upper middle position of the cover. The stirring shaft is fixedly connected to the lower end of the output shaft of the first motor. The connecting block is fixedly connected to the middle position of the left and right ends of the cover. The spring is connected to the lower inner end of the connecting block. The plug rod is fixedly connected to the front end of the spring. The connecting frame is fixedly connected to the middle position of the upper ends of the left and right sides of the liquid storage tank.

[0012] Preferably, the upper outer side of the liquid inlet hopper is provided with an external thread, and the inner side of the cap is provided with an internal thread. The upper outer side of the liquid inlet hopper is threadedly connected to the inner side of the cap, thereby facilitating the installation and removal of the cap from the upper end of the liquid inlet hopper.

[0013] Preferably, a circular groove is provided at the lower front end of the inner side of the connecting block, the rear end of the spring is fixedly connected to the inner rear end of the circular groove, and the outer side of the insertion rod is slidably connected to the inner side of the circular groove, so that when the spring bounces, the insertion rod can be driven to slide along the inner side of the circular groove.

[0014] Preferably, an insertion hole is provided at the center of the front end of the connecting frame. The outer front end of the insertion rod is inserted into the inner side of the insertion hole, and the outer lower end of the connecting block is slidably connected to the inner side of the connecting frame. Thus, when the lid is placed on top of the storage tank, and the connecting block slides to the inner side of the connecting frame, the spring-loaded push rod is pushed forward into the insertion hole at the front end of the connecting frame, fixing the connecting block inside the connecting frame and thus fixing the lid to the top of the storage tank.

[0015] Preferably, the cutting unit includes a second motor connecting rod and a cutting blade. The second motor is fixedly connected to the front and rear ends of the lower middle position of the vehicle body. The connecting rod is fixedly connected to the lower end of the output shaft of the second motor, and the cutting blade is fixedly connected to the lower end of the connecting rod.

[0016] Preferably, the height of the cutting blade is higher than the bottom of the vehicle body, so that by starting the second motor and rotating its output shaft, the connecting rod and the cutting blade can be rotated, thereby cutting the weeds in the area where the vehicle body passes.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. This agricultural robot, capable of quickly and accurately spraying pesticides, can draw pesticides from its storage tank into a water pipe by activating a water pump. The pesticides then enter a circular pipe and are sprayed onto crops at the front and rear ends of the vehicle through a nozzle. Furthermore, by activating the telescopic component, the output shaft moves, causing the circular pipe to move up and down, which in turn changes the height of the nozzle, allowing pesticide spraying to be performed on crops at different heights.

[0019] 2. This agricultural robot, which can quickly and accurately spray pesticides, moves to the inside of the circular groove by pushing the insert rod, and then pulls up the box cover to move the connecting block out from the inside of the connecting frame. The box cover is then removed from the top of the liquid storage tank, and the residual pesticide in the liquid storage tank can be cleaned to prevent the pesticide from evaporating into the air and causing harm when the equipment is not working.

[0020] 3. This agricultural robot, which can quickly and accurately spray pesticides, can cut weeds in the area it passes through by starting the second motor and rotating its output shaft to drive the connecting rod and cutting blades while the vehicle is moving and spraying pesticides.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0030] Please see Figures 1-5 The present invention provides a technical solution:

[0031] Example 1:

[0032] An agricultural robot capable of rapidly and accurately spraying pesticides includes a vehicle body 1 and a liquid storage tank 2. The liquid storage tank 2 is fixedly connected to the upper left side of the vehicle body 1. A tank cover 3 is connected to the upper end of the liquid storage tank 2. An inlet hopper 4 is fixedly connected to the upper left side of the inside of the tank cover 3. Spraying mechanisms are connected to the upper and lower ends of the vehicle body 1. The spraying mechanism includes a spraying unit, a cleaning unit, and a cutting unit. The spraying unit is located at the upper and lower ends of the vehicle body 1, the cleaning unit is located at the outer end of the liquid storage tank 2, and the cutting unit is located at the lower end of the vehicle body 1.

[0033] The spraying unit includes a telescopic component 501, a circular pipe 502, a nozzle 503, a water pump 504, and a water pipe 505. The telescopic component 501 is fixedly connected to the middle of the front and rear ends of the lower side of the vehicle body 1. The telescopic component 501 is a cylinder. The circular pipe 502 is fixedly connected to the upper end of the output shaft of the telescopic component 501. The nozzle 503 is fixedly connected to the end of the circular pipe 502 away from the liquid storage tank 2. The water pump 504 is fixedly connected to the right end of the liquid storage tank 2. The water pipe 505 is fixedly connected to the right end of the water pump 504. The end of the water pipe 505 away from the water pump 504 is fixedly connected to the middle of the end of the circular pipe 502 near the water pump 504. By activating the water pump 504, pesticides in the storage tank 2 can be drawn into the water pipe 505, and then into the round pipe 502 through the water pipe 505. After that, the pesticides are sprayed out through the nozzle 503 onto the crops at the front and rear ends of the vehicle body 1. Furthermore, by activating the telescopic component 501, the output shaft moves, causing the round pipe 502 to move up and down, which in turn changes the height of the nozzle 503, allowing pesticides to be sprayed onto crops at different heights.

[0034] The cleaning unit includes a cover 601, a first motor 602, a stirring shaft 603, a connecting block 604, a spring 605, a plug rod 606, and a connecting frame 607. The cover 601 is connected to the outer side of the upper end of the liquid inlet 4. The outer side of the upper end of the liquid inlet 4 has external threads, and the inner side of the cover 601 has internal threads. The outer side of the upper end of the liquid inlet 4 is threadedly connected to the inner side of the cover 601. This facilitates the removal and installation of the cover 601 from the upper end of the liquid inlet 4, allowing it to be threadedly connected to the upper end of the liquid inlet 4 during operation, preventing pesticides from splashing out of the tank cover 3.

[0035] The first motor 602 is fixedly connected to the upper middle position of the cover 3, and the stirring shaft 603 is fixedly connected to the lower end of the output shaft of the first motor 602. Thus, when the output shaft of the first motor 602 is started and rotated, the stirring shaft 603 is driven to rotate, which can stir the pesticide in the storage tank 2 and prevent the pesticide in the storage tank 2 from settling.

[0036] The connecting block 604 is fixedly connected to the middle of the left and right ends of the cover 3. The spring 605 is connected to the lower inner end of the connecting block 604. The insertion rod 606 is fixedly connected to the front end of the spring 605. The connecting frame 607 is fixedly connected to the middle of the upper left and right sides of the liquid storage tank 2. A circular groove is formed at the lower front end of the inner part of the connecting block 604. The rear end of the spring 605 is fixedly connected to the inner rear end of the circular groove, and the outer side of the insertion rod 606 is slidably connected to the inner side of the circular groove. Thus, when the spring 605 springs, it can drive the insertion rod 606 to slide along the inner side of the circular groove, thereby limiting the movement of the insertion rod 606.

[0037] An insertion hole is provided at the center of the front end of the connecting frame 607. The outer front end of the insertion rod 606 is inserted into the inner side of the insertion hole, and the outer lower end of the connecting block 604 is slidably connected to the inner side of the connecting frame 607. Thus, when the lid 3 is placed on the upper end of the liquid storage tank 2, and the connecting block 604 slides to the inner side of the connecting frame 607, the spring 605 pushes the insertion rod 606 forward, pushing it into the insertion hole at the front end of the connecting frame 607. This fixes the connecting block 604 to the inside of the connecting frame 607, thereby fixing the lid 3 to the upper end of the liquid storage tank 2.

[0038] Example 2:

[0039] Based on Embodiment 1: The cutting unit includes a second motor 701, a connecting rod 702, and a cutting blade 703. The second motor 701 is fixedly connected to the front and rear ends at the lower center of the vehicle body 1. The connecting rod 702 is fixedly connected to the lower end of the output shaft of the second motor 701, and the cutting blade 703 is fixedly connected to the lower end of the connecting rod 702. The height of the cutting blade 703 is higher than the bottom of the vehicle body 1. Thus, during the process of the vehicle body 1 moving and spraying pesticides, by starting the second motor 701 and rotating its output shaft, the connecting rod 702 and the cutting blade 703 can be rotated, thereby cutting the weeds in the area where the vehicle body 1 passes, achieving the function of weed control.

[0040] When in use, first inject the pesticide into the storage tank 2 through the inlet hopper 4, then thread the cap 601 to the upper end of the inlet hopper 4. Next, start the robot body 1 and drive it in the crop planting field. During the driving process, start the water pump 504 and the second motor 701. The water pump 504 draws the pesticide from the storage tank 2 into the water pipe 505, and then enters the round pipe 502 through the water pipe 505 and sprays it onto the crops at both ends of the front and rear of the body 1 through the nozzle 503. At the same time, the output shaft of the second motor 701 rotates, driving the connecting rod 702 and the cutting blade 703 to rotate. The cutting blade 703 cuts and removes weeds in the area where the body 1 passes.
