DETAILED DESCRIPTION

[0026] The present application discloses a plant protection robot. To make the purpose, technical solution and effect of the present application clearer and more specific, the present application is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific examples described here are only used to explain the present application and are not used to limit the present application.

[0027] like Figure 1 and Figure 2 As shown, the embodiment of the present application discloses a plant protection robot, which includes:

[0028] A chassis 1, wherein a rotating wheel 11 is rotatably provided on the bottom surface of the chassis 1, and the rotating wheels 11 are distributed at the four corners of the bottom surface of the chassis 1 to ensure the stable driving of the robot; a liquid storage barrel 2 is fixedly provided on the top surface of the chassis 1, and a feeding port 3 is provided on the liquid storage barrel 2, and liquid is added into the liquid storage barrel 2 through the feeding port 3; and a spray irrigation component 4 is arranged on the front side of the chassis 1 for spray irrigation during plant protection; and a baffle component 5 is arranged inside the liquid storage barrel 2 for alleviating the shaking of the liquid inside the liquid storage barrel 2 during movement.

[0029] During the plant protection operation of the spray irrigation robot, the bumpy road surface will cause the liquid in the liquid storage barrel 2 to slosh severely, thereby affecting the stability of the spray irrigation and driving. In severe cases, it may even cause the robot to overturn. In this regard, the present application provides a baffle assembly 5, which reduces the amplitude and frequency of the liquid sloshing in the liquid storage barrel 2, thereby reducing the degree of liquid sloshing and ensuring the driving and irrigation stability of the plant protection robot.

[0030] Specifically, in some embodiments, the baffle assembly 5 includes a plurality of mounting shafts 51 rotatably connected to the liquid storage barrel 2, and each mounting shaft 51 is provided with a baffle plate 52 for blocking the liquid flowing inside the liquid storage barrel 2, and the baffle plate 52 is arranged along the height direction of the liquid storage barrel 2, that is, perpendicular to the direction of liquid flow, so that the baffle plate 52 can slow down the sloshing of the liquid in the liquid storage barrel 2. It is understandable that the baffle assembly 5 can also be arranged along the width direction of the liquid storage barrel 2, that is, perpendicular to the direction of liquid flow.

[0031] When the plant protection robot travels on a bumpy road, the liquid in the liquid storage barrel 2 shakes violently, and the liquid passes through each baffle plate 52. Since the baffle plates 52 are arranged in a direction perpendicular to the liquid flow, the baffle plates 52 can block the liquid inside the liquid storage barrel 2, thereby reducing the amplitude and frequency of the liquid shaking and ensuring the stability of the robot's travel and irrigation.

[0032] During the process of the baffle plate 52 blocking, the liquid also has an impact on the baffle plate 52, thereby causing the baffle plate 52 and the mounting shaft 51 to rotate. If the baffle plate 52 rotates easily, that is, parallel to the direction of the liquid flow, the baffle plate 52 will not be able to block the liquid. Therefore, in some embodiments of the present application, reference is made to Figure 2 and Figure 3 As shown, the plant protection robot is also provided with a friction component 6 for generating resistance to the rotation of the baffle component 5, and an elastic squeezing component 7 for elastically squeezing the friction component 6. Through the friction between the friction component 6 and the baffle component 5, a friction resistance is provided for the rotation of the baffle component 5, so that the rotation speed of the baffle component 5 is slowed down, thereby alleviating the amplitude and frequency of the liquid sloshing in the liquid storage barrel 2. And the friction component 6 is adaptively changed by the elastic squeezing component 7, so that when the baffle component 5 rotates, the baffle component 5 will also generate friction resistance with the friction component 6, thereby slowing down the rotation speed of the baffle component 5, and alleviating the amplitude and frequency of the liquid sloshing in the liquid storage barrel 2.

[0033] In some embodiments, the friction component 6 is arranged at the upper end of the liquid storage barrel 2, and the friction component 6 is located on one side of the mounting shaft 51, and is used to generate resistance to the rotation of the mounting shaft 51. In the present application, the friction component 6 is provided with two groups, and the two groups of friction components 6 are respectively located on both sides of the mounting shaft 51 to generate balanced friction resistance to the baffle component 5, and sufficient resistance to slow down the rotation of the baffle component 5.

[0034] Specifically, the friction assembly 6 includes a strip plate 61 slidably disposed on the upper end of the liquid storage barrel 2, and a plurality of friction blocks 62 are fixed on the strip plate 61. Each friction block 62 is disposed corresponding to each mounting shaft 51. As can be seen in the figure, two friction blocks 62 are symmetrically disposed on both sides of the mounting shaft 51. An arc groove 63 is provided on the friction block 62, and the arc groove 63 abuts against the outer side of the mounting shaft 51. The mounting shaft 51 is cylindrical, and the design of the arc groove 63 is adapted to the shape of the mounting shaft 51, so that when the mounting shaft 51 rotates, friction resistance is generated with the mounting shaft 51.

[0035] In actual use, when the liquid in the liquid storage barrel 2 sways, and then transmits to cause the baffle plate 52 and the mounting shaft 51 to rotate, due to the mutual squeezing contact between the friction block 62 and the mounting shaft 51, friction resistance will be generated between the friction block 62 and the mounting shaft 51, preventing the rotation of the mounting shaft 51, thereby slowing down the rotation of the baffle plate 52, slowing down the amplitude of the liquid sloshing, and thus improving the stability of the plant protection robot's spray irrigation and driving. In essence, it can be understood that setting up one group of friction components 6 can also achieve the effect of slowing down the rotation of the mounting shaft 51 (baffle plate 52), and setting up two groups can block the entire circumference of the mounting shaft 51, and the blocking effect is better.

[0036] In some embodiments, the elastic extrusion assembly 7 includes a fixed plate 71 fixedly arranged at the upper end of the liquid storage barrel 2, and a plurality of sleeves 72 are connected to the fixed plate 71, and each of the sleeves 72 is slidably connected to a slide rod 73, and one end of the slide rod 73 is connected to the strip plate 61; a spring 74 is sleeved on the outer side of the sleeve 72, and the two ends of the spring 74 are respectively abutted against the strip plate 61 and the fixed plate 71.

[0037] In the specific implementation, in the initial state, the mounting shaft 51 and the friction block 62 are tightly connected. When the mounting shaft 51 rotates under the action of the liquid, due to the action of the spring 74, the strip plate 61 can slide back and forth above the liquid storage barrel 2 along the direction of the sleeve 72, so that a gap can be generated between the mounting shaft 51 and the friction block 62, so that the mounting shaft 51 can rotate relative to the friction block 62. However, since the spring 74 (in a compressed state) has elastic potential energy, the spring 74 will compress the strip plate 61 to move toward the mounting shaft 51, and the mounting shaft 51 and the friction block 62 will not be completely separated. Therefore, the friction block 62 can still provide friction resistance for the rotation of the mounting shaft 51, thereby ensuring the effect of slowing down the rotation speed of the mounting shaft 51, and thereby slowing down the amplitude of the liquid shaking in the liquid storage barrel 2.

[0038] In some embodiments, the spray irrigation assembly 4 includes a mounting frame 41 fixed to the front side of the liquid storage barrel 2, a spray head 42 is mounted on the mounting frame 41, a delivery pipe 43 is connected between the spray head 42 and the liquid storage barrel 2, a water pump 44 is installed inside the liquid storage barrel 2, and one end of the delivery pipe 43 is connected to the water outlet of the water pump 44. When the plant protection robot performs spray irrigation, the liquid in the liquid storage barrel 2 is pumped out to the delivery pipe 43 connected to the water outlet of the water pump 44 through the water pump 44, and then the liquid is sprayed into the field through the spray head 42 connected to the delivery pipe 43, thereby realizing automated field operations.

[0039] To sum up, the principle of the embodiment of the present application is: during the plant protection operation of the spray irrigation robot, due to the bumpy road surface, the liquid in the liquid storage barrel 2 will shake more severely, thereby affecting the spray irrigation and driving stability. In severe cases, it may also cause the robot to overturn. In this regard, the present application has made improvements. When the liquid in the liquid storage barrel 2 shakes, it will have an impact on the baffle plate 52, causing the baffle plate 52 and the mounting shaft 51 to rotate. If the baffle plate 52 rotates easily, it will not be able to alleviate the liquid shaking. At this time, the spring 74 arranged on one side of the mounting shaft 51 has elastic potential energy, and the guide rod can be retracted into the sleeve 72, so that the spring 74 can drive the strip plate 61 to slide toward or away from the mounting shaft 51 through the guide rod, so that when the mounting shaft 51 rotates, there is a gap between the mounting shaft 51 and the friction block 62, but they are also connected to each other, that is, while the mounting shaft 51 can rotate, a friction resistance will also be generated between the friction block 62 and the mounting shaft 51 to slow down the rotation speed of the mounting shaft 51, thereby slowing down the amplitude and frequency of the liquid shaking in the liquid storage barrel 2, thereby ensuring the stability of the plant protection robot in driving and irrigation.

[0040] Compared with the prior art, the utility model has the following advantages:

[0041] 1. The present application sets a baffle assembly 5 to block the flow of liquid in the liquid storage barrel 2, thereby reducing the amplitude and frequency of liquid shaking in the liquid storage barrel 2, slowing down the degree of liquid shaking, and improving the driving and irrigation stability of the plant protection robot.

[0042] 2. During the blocking process, the shaking of the liquid in the liquid storage barrel 2 will generate a force on the blocking component 5, causing the blocking component 5 to rotate. In this regard, the present application provides a friction component 6 on one side of the blocking component 5, so that when the blocking component 5 rotates, the friction between the friction component 6 and the blocking component 5 provides a friction resistance for the rotation of the blocking component 5, so that the rotation of the blocking component 5 is slowed down, thereby alleviating the amplitude of the liquid shaking in the liquid storage barrel 2.

[0043] 3. The present application sets an elastic squeezing component 7 to perform elastic squeezing on the friction component 6, thereby ensuring that the baffle component 5 generates friction resistance with the friction component 6 while rotating, thereby slowing down the rotation speed of the baffle component 5 and alleviating the amplitude and frequency of the liquid shaking in the liquid storage barrel 2.

[0044] It should be understood that the application of the present application is not limited to the above examples. For ordinary technicians in this field, improvements or changes can be made based on the above description. All these improvements and changes should fall within the scope of protection of the claims attached to this application.
