Description

Technical Field

[0001] The utility model relates to the technical field of agricultural unmanned vehicles, and particularly relates to an agricultural unmanned spraying vehicle. Background Art

[0002] Unmanned vehicles mainly apply driverless technology and control the vehicle to travel along a predetermined route through wireless data transmission. Unmanned vehicles have been applied in various industries, such as daily travel vehicles, unmanned vehicle inspections, etc. In agriculture, operations such as spraying and pesticide application on the ground are usually required. The manual spraying method has a large labor intensity and low efficiency, and is only suitable for small-scale planting areas; the mechanical spraying method usually uses a tractor to carry spraying equipment for spraying. This method requires relatively professional personnel to operate and has a high labor cost. Therefore, the use of unmanned vehicles for spraying has been applied.

[0003] In order to improve the spraying efficiency of existing spraying unmanned vehicles, generally, a long rod is fixed on the unmanned vehicle, and then the spraying pipeline is tied to the long rod, and the long rod is arranged on top of the crops for large-area spraying; for example, the utility model patent with the Chinese publication number CN215819722U discloses "an agricultural unmanned vehicle", which includes a bearing structure, a control device, driving wheels, a spray rod and nozzles. The spray rod is arranged along the width direction of the vehicle body. As the vehicle body moves, pesticides are sprayed at the nozzles of the spray rod to achieve large-range spraying; however, the above device only sprays on the top of the crops. When the crops have lush branches and leaves, pesticides cannot reach the branches and leaves inside or at the bottom, resulting in poor pest control effect of the pesticides.

[0043] In view of the deficiencies of the prior art, this embodiment provides an agricultural unmanned spraying vehicle, which can be specifically referred to as follows:

[0044] As shown in the attached Figure 1 and attached Figure 2As shown in the figure, an agricultural unmanned spraying vehicle includes a frame body 1, a water storage tank 2, a U-shaped frame 3, two spraying pipes 4, and a driving assembly 5. The water storage tank 2 and the U-shaped frame 3 are arranged on the frame body 1. Spraying pipes 4 are respectively arranged on both sides of the U-shaped frame 3. A plurality of nozzles 41 are arranged on the spraying pipes 4. The nozzles 41 are arranged at a certain angle with the U-shaped frame 3, that is, the nozzles 41 are inclined from bottom to top or from top to bottom, so as to facilitate spraying pesticides onto the internal branches and leaves. A driving assembly 5 is also arranged at the bottom of the frame body 1. The driving assembly 5 is used to drive the frame body 1 to move; by arranging a U-shaped pipe, the spraying pipes 4 and the nozzles 41 on the frame body 1, spraying can be realized on both sides of the U-shaped pipe, and under the action of the driving assembly 5, mobile spraying can be carried out; the nozzles 41 on both sides of the U-shaped pipe can directly aim at the branches and leaves on one side of the crops, which can not only make both rows of crops be sprayed with pesticides, but also spray the crops in the largest range, thereby effectively improving the efficiency of pest control.

[0045] Specifically, a remote controller and a controller are also arranged inside the unmanned vehicle. The controller is connected to the driving assembly 5 and the remote controller. By sending a signal from the remote controller to the controller, the controller sends signals to the driving assembly 5 and the internal spraying control assembly, etc. The driving assembly 5 drives the unmanned vehicle to move along a specified or designed route, and the spraying control assembly controls the nozzles 41 to spray pesticides; the unmanned vehicle itself can also be used for transportation. The water storage tank 2, the nozzles 41 and the spraying pipes 4 can be removed. A cavity is arranged on the frame body 1, which can be used to hold goods and is controlled to move through the remote controller.

[0046] In an embodiment of the present application, as shown in the appendix Figure 2 As shown in the figure, the U-shaped frame 3 includes two first fixing rods 31, two second fixing rods 32, two third fixing rods 33, and a fourth fixing rod 34. The two first fixing rods 31 are respectively arranged at both ends of the frame body 1 and are located on the front side of the frame body 1. The two second fixing rods 32 correspond to the two first fixing rods 31 one by one. One ends of the two second fixing rods 32 are respectively arranged on the tops of the two first fixing rods 31, and the other ends of the two second fixing rods 32 are inclined towards each other, presenting a triangular shape to reduce the distance between the two second fixing rods 32. The two third fixing rods 33 correspond to the two second fixing rods 32 one by one, and the two third fixing rods 33 are respectively arranged on the tops of the two second fixing rods 32. The two third fixing rods 33 are arranged vertically. Due to the inclined arrangement of the two second fixing rods 32, the distance between the two third fixing rods 33 is smaller than the distance between the two first fixing rods 31. A fourth fixing rod 34 is arranged between the two third fixing rods 33, and both ends of the fourth fixing rod 34 are respectively connected to the two third fixing rods 33 to play a fixing role.

[0047] The first fixing rod 31, the second fixing rod 32, the third fixing rod 33 and the fourth fixing rod 34 are all tubular, and are formed by reasonably bending a round tube. The bending parts of the U-shaped frame 3 are all connected by arc tubes. By arranging the two second fixing rods 32 to incline towards each other, the distance between the tops of the U-shaped frame 3 can be reduced, so as to avoid crops with lush branches and leaves, and avoid the tops of the U-shaped frame 3 from colliding with the branches and leaves, causing the branches and leaves to fall or be damaged. At the same time, there is also a certain release distance for the pesticides sprayed by the nozzles 41, so that the pesticides can be dispersed in a fan shape or other shapes to cover a larger area of crops. At the same time, by arranging the second fixing rod 32 to be inclined, the nozzles 41 fixed on the second fixing rod 32 can be arranged obliquely, so as to facilitate spraying on the branches or leaves.

[0048] In this embodiment, two nozzles 41 are arranged on the spraying pipe 4. The two nozzles 41 are respectively arranged on the second fixing rod 32 and the third fixing rod 33. The second fixing rod 32 is arranged obliquely, and the third fixing rod 33 is arranged vertically. One of the two nozzles 41 is arranged obliquely and the other is arranged horizontally, so as to ensure that the sides of the crops can be evenly sprayed with pesticides.

[0049] In this embodiment, the nozzle 41 is arranged on the U-shaped frame 3 through a snap ring 6. Specifically, a first U-shaped sleeve is arranged on one side of the nozzle 41, and then a second U-shaped sleeve is arranged on the U-shaped frame 3. Through holes are respectively arranged on both sides of the first U-shaped sleeve and the second U-shaped sleeve and are correspondingly arranged. The first U-shaped sleeve and the second U-shaped sleeve are fixed by bolts, and the bolts are fixed in the through holes.

[0050] In this embodiment, the second fixing rod 32, the third fixing rod 33 and the fourth fixing rod 34 are all electric telescopic rods. The electric telescopic rods are electrically connected to the controller. By contracting and opening the second fixing rod 32, the height of the nozzle 41 located on the second fixing rod 32 can be adjusted, so as to be applicable to more crops. When the second fixing rod 32 contracts or opens, if it is not necessary to adjust the nozzle 41 on the third fixing rod 33, then it can be achieved by adjusting the contraction or elongation of the third fixing rod 33. At the same time, the contraction and elongation of the fourth fixing rod 34 can also be changed according to the length changes of the second fixing rod 32 and the third fixing rod 33.

[0051] Furthermore, the fourth fixing rod 34 can be a telescopic rod, which does not require electric drive or locking. When the second fixing rod 32 contracts, the fourth fixing rod 34 elongates, and when the second fixing rod 32 elongates, the fourth fixing rod 34 contracts.

[0052] Furthermore, the snap ring 6 and the first U-shaped ferrule on the nozzle 41 can move and can be set at different positions on the second fixed rod 32 and the third fixed rod 33. By moving the nozzle 41, spraying on different crops can be achieved, thereby realizing the multi-functional spraying function of the unmanned spraying vehicle.
