[0040] Example 1
[0041] like Figure 1 As shown, the present invention proposes a multi-terrain adaptive bionic soil covering device, which is based on the multi-segment design of a centipede and utilizes the multi-angle adjustment function of the adjustment component 2 to meet the soil covering operation of different types of soil and planting pits; specifically, it includes a connecting component 1 installed in conjunction with agricultural machinery, an adjustment component 2 set at the extension end of the connecting component 1, and a guide component 3 fixed on the adjustment component 2.
[0042] In this embodiment, the soil covering device is connected to the agricultural machinery via the connecting component 1. The agricultural machinery drives the soil covering device to cover the planting pit with soil at the rear of the machinery. The adjusting component 2 changes shape under the control of the motor and the traction wire 26, bringing the guiding component 3 into contact with the soil covering. As the agricultural machinery moves, the guiding component 3 pushes the soil covering into the planting pit, leveling the pit. All motors are stepper motors. When the traction wire moves to the designated position, the motor stops and remains self-locking, keeping the adjusting component 2 in the corresponding shape. The traction wire 26 can be a flexible steel wire or a nylon rope. Specifically, the connecting assembly 1 includes a connecting hook 11, a mounting base 12, and a housing 14. The mounting base 12 provides an installation platform for the entire connecting assembly 1. The housing 14 is located at the bottom of the mounting base 12. The housing 14 is hollow inside and is divided into several chambers with multiple layers by partitions. Each chamber is equipped with a motor for controlling the movement of the traction wire 26. Motors that control the deflection of the same movable piece are located in the same layer. Different motors are separated by partitions to prevent interference. In actual operation, all motors first pull the traction wire to keep the elastic element 24 in a contracted state, that is, the entire adjusting assembly 2 is in a pre-tightened state. When it is necessary to adjust the shape of the adjusting assembly 2, the traction wire is slowly released by controlling a designated motor to cause it to twist. Multiple motors work together to ultimately achieve the adjustment of the overall shape of the adjusting assembly 2.
[0043] like Figure 2As shown, in this embodiment, the connecting hook 11 is disposed on the top of the mounting base 12 and is used to connect with agricultural machinery. By changing the angle at which the connecting hook 11 connects with the agricultural machinery, the deflection angle of the soil covering device can be changed. Specifically, components adapted to the connecting hook 11 are installed on the agricultural machinery. Common components can be fastened using clamps and bolts. After fastening, they form a whole. During use, the angle of the soil covering device 2 can be adjusted by changing the angle of the adapted components so that the angle rotates around the axis, thereby adjusting the final deflection angle to suit different terrains.
[0044] In this embodiment, the mounting base 12 is also provided with several plug-in connectors 13 for power supply and communication; the external power supply is connected to the plug-in connectors 13 to supply power to the motor installed in the machine compartment 14; the communication line is connected to the host computer through the plug-in connectors 13 to receive control commands from the host computer and control the adjustment component 2 to bend to a suitable angle.
[0045] like Figure 2-3 As shown, the lower part of the housing 14 extends downward, and several fixing rods 15 are provided at the extended end; three fixing rods 15 are provided, and adjacent fixing rods 15 form a 60° angle; the adjustment component 2 includes a fixing plate 21, a first movable plate 22, and a second movable plate 23; the fixing plate 21 is located at the top, and the first movable plate 22 and the second movable plate 23 are arranged in sequence; independent elastic elements 24 for support are respectively provided between the fixing plate 21 and the first movable plate 22, and between the first movable plate 22 and the second movable plate 23; through holes are provided in the middle of the fixing plate 21, the first movable plate 22, and the second movable plate 23, and dust covers 16 are provided at the through holes; the top of the dust cover 16 is fixed to the bottom of the housing 14, and the bottom is fixed to the second movable plate 23. The dust cover 16 itself is an elastic telescopic structure, and its interior forms a protective structure to protect the traction wire; the traction wire is located inside the dust cover 16; three sets of traction wires are fixed to the first movable plate 22, and three sets of traction wires are fixed to the second movable plate 23.
[0046] like Figure 6 As shown, the traction wires of the first movable piece 22 and the second movable piece 23 are misaligned; the traction wires of the first movable piece 22 are spaced 60° apart, and the traction wires of the second movable piece 23 are also spaced 60° apart.
[0047] like Figure 2 As shown, the guide assembly 3 includes a first guide plate 31, a second guide plate 32, and a third guide plate 33; the first guide plate 31 is connected to the fixed plate 21; the second guide plate 32 is connected to the first movable plate 22; and the third guide plate 33 is connected to the third guide plate 23. Figure 4As shown, slots 231 are provided on the fixed plate 21, the first movable plate 22 and the third guide plate 23; connecting seats 25 are provided on the first guide plate 31, the second guide plate 32 and the third guide plate 33; the connecting seats 25 are inserted into the slots 231 and fastened with bolts.
[0048] In this embodiment, as Figure 5 The first guide plate 31 and the second guide plate 32 shown are both thin metal sheets. The first guide plate 31 is inclined downward along the fixed plate 21, and the side of the first guide plate 31 in contact with the soil is deflected by 3-8°. The second guide plate 32 is inclined downward along the first movable plate 22, and the side of the second guide plate 32 in contact with the soil is deflected by 3-8°.
[0049] like Figure 7 As shown, the third guide plate 33 is a thin metal sheet. The third guide plate 33 is inclined downward along the second movable plate 22, and the side of the third guide plate 33 in contact with the soil is deflected by 10-15°.
[0050] like Figure 8-9 As shown, after the adjusting component 2 bends at a certain angle, the first guide plate 31 guides the soil toward the second guide plate 32 and the third guide plate 33; the third guide plate 33 pushes the soil to cover and level the planting pit.
[0051] In this embodiment, the soil covering device is driven by agricultural machinery. The curvature of the soil covering device can be adjusted as needed, such as... Figure 8 When installed with agricultural machinery, the connecting assembly 1 can be tilted downwards; the first guide plate 31 and the second guide plate 32 can be located on the same horizontal plane, or the height of the second guide plate 32 can be lower than that of the first guide plate; simultaneously, the position of the third guide plate 33 can be adjusted to be lower, and through the triple guiding action, the soil covering the planting pit is leveled; as shown Figure 9 As shown, by adjusting component 2, the second movable piece 23 is kept bent relative to the first movable piece 22. At this point, only one set of covering devices is needed to complete the covering of the seed pit. Conventional agricultural machinery, because the sowing device is located in the middle of the machinery, requires covering devices to be placed on both sides to avoid interference with the sowing component; therefore, at least two sets of devices are needed to work together to complete the task. However, this application only requires one set of equipment to complete the same task. Furthermore, when it is necessary to adjust the depth of the guide piece, the angle of the covering component can be adjusted to... Figure 9 For example, by rotating it counterclockwise by a certain angle, the guide plate can be deflected downwards and extended into a deeper soil layer, thus making it suitable for planting pits of different depths.
[0052] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
