[0041] See also Figure 1-Figure 6 .

[0042] Some embodiments of the present application disclose a deep tillage machine, including a tractor 6 and a deep tillage plow 1. The deep tillage plow 1 is installed at the rear of the tractor 6. The tractor 6 is used to provide traction to the deep tillage plow 1. The tractor 6 is connected to the deep tillage machine through a suspension mechanism 2. The suspension mechanism 2 is used to transmit the traction of the tractor 6 to the deep tillage machine and keep the deep tillage machine in a correct working position so that the deep tillage machine can perform deep tillage, harrowing and rotary tillage on the land.

[0043] The tractor 6 adjusts the relative position of the deep tiller and the tractor 6 through the lifter 3, thereby adjusting the deep tilling depth of the deep tiller. The lifter 3 includes a lift arm 31 and a lift cylinder 32. The angle of the lift arm 31 is adjusted by telescopically adjusting the telescopic rod of the lift cylinder 32, thereby completing the adjustment of the deep tilling depth of the deep tiller before operation.

[0044] The deep tillage plow 1 comprises a frame 11 and a plow 12 . The frame 11 is connected to the tractor 6 via a suspension mechanism 2 and a lifter 3 , and the plow 12 is mounted on the frame 11 .

[0045] The deep tilling machine disclosed in the present embodiment also includes an adjusting device for adjusting the deep tilling depth of the deep tilling plow 1 when the deep tilling depth of the deep tilling plow 1 exceeds a preset deep tilling depth range.

[0046] In some embodiments, the adjustment device includes an angle collector, an adjustment component, and a controller.

[0047] The angle collector is used to collect the angle of the lifting arm 31 of the lifter 3 and transmit the collected angle of the lifting arm 31 to the controller;

[0048] The plow 12 is connected to the frame 11 through an adjustment component, and the adjustment component is used to adjust the distance between the plow 12 and the ground, thereby adjusting the deep plowing depth of the plow 12, and the adjustment component is in communication with the controller;

[0049] The controller is used to control the adjustment component to operate when the angle of the lifting arm 31 collected by the angle collector exceeds a preset angle range, so that the adjustment component adjusts the deep plowing depth of the coulter 12 .

[0050] After the deep plowing depth of the deep plowing plow 1 is adjusted by the lifter 3 according to the deep plowing demand before the operation, the deep plowing depth of the deep plowing plow 1 will change during the operation. In the related art, the deep plowing depth is adjusted by manually operating the lifter 3, and the adjustment process mainly relies on the user's experience.

[0051] The deep tilling machine disclosed in this scheme can adjust the deep tilling depth of the deep tilling machine during its operation, and the adjustment process is real-time adjustment, ensuring that the deep tilling depth of the deep tilling machine is always within a preset range. The deep tilling machine does not need to be shut down, and the working efficiency of the deep tilling machine is not affected.

[0052] Specifically, the angle of the lifting arm 31 of the lifter 3 is collected in real time by the angle collector, and the collected angle of the lifting arm 31 is sent to the controller, and the controller compares the angle of the lifting arm 31 collected by the angle collector with the preset angle range. If the angle of the lifting arm 31 collected by the angle collector is within the preset angle range, the controller does not control the adjustment component to adjust the distance between the plow 12 and the ground. If the angle of the lifting arm 31 collected by the angle collector exceeds the preset angle range, the controller controls the adjustment component to adjust the distance between the plow 12 and the ground to adjust the deep plowing depth of the plow 12, so that the deep plowing depth of the deep plowing machine is always maintained within the preset deep plowing depth range, thereby realizing automatic adjustment of the deep plowing depth of the deep plowing machine.

[0053] like Figure 4 and Figure 5 As shown, it is a scene where the deep tillage machine is working on a relatively long uphill or downhill slope, with the tractor 6 in front and the deep tillage plow 1 in the back, and the angle collector collects the angle of the lifting arm 31.

[0054] like Figure 4 and Figure 5 As shown in the figure, H is the set deep plowing depth, and α is D is the angle of the lifting arm 31 collected by the angle collector, h p The change in the deep plowing depth of the deep plow 1 when the deep plow is uphill or downhill is obtained by fitting the polynomial function. D With h p Relationship:

[0058] Specifically, the sliding portion 42 is a slider, the guide portion 41 is a slideway, and the slider and the slideway guide are slidably matched.

[0072] In some embodiments, a filter is disposed at one end of the oil inlet pipe connected to the hydraulic oil tank 52 .

[0073] During operation, the hydraulic oil pump 53 pumps hydraulic oil to the hydraulic cylinder 51, so that the telescopic rod of the hydraulic cylinder 51 extends or retracts, and the telescopic rod drives the sliding part 42 to move up and down, thereby adjusting the distance between the plow blade 12 and the ground.

[0074] In this solution, the hydraulic system and the coulter 12 are integrated structures, which are independent of the hydraulic system of the tractor 6, thereby improving the integrity and working efficiency of the deep plow 1 and the compatibility with the tractor 6.
