Detailed Description
The structure of the present system and the functions performed are described in detail below with reference to the accompanying drawings.
A device for loosening soil compacted by tires of farm implements tractor comprises a soil loosening mechanism 1, a photoelectric sensor 2 and a control part 3, wherein the control part 3 dynamically controls the operation of the soil loosening mechanism 1 according to the detection result of the photoelectric sensor 2;
loosening mechanism 1 includes support 11, crossbeam 12, a plurality of plow standard 13, a plurality of fixed coulters 14, a plurality of rotatory plow harrow 15, wherein:
one end of the support 11 is connected with the farm tool tractor, and the other end is fixed with a cross beam 12;
a plurality of plow columns 13 are arranged on the beam 12 at equal intervals, and a plurality of fixed coulters 14 are arranged below the plow columns 13 positioned in the middle of the beam;
a plurality of rotatory plow harrow 15, its fix in the crossbeam left and right sides and the plow standard 13 below that agricultural implement tractor tire corresponds, include:
the rotating bracket 151 is arranged below the plow standard 13, the rotating bracket 151 is provided with a long rake tooth 152 and a short rake tooth 153, and the long rake tooth 152 and the short rake tooth 153 are spaced by 180 degrees;
a motor 154 mounted on the support 11 for driving the rotation bracket 151 to rotate;
the soil loosening mechanism 1 is connected with an agricultural implement tractor through a support 11, and when the agricultural implement tractor advances, rake teeth enter soil to perform soil loosening operation;
the photoelectric sensor 2 is arranged on the plow standard 13, the installation position of the photoelectric sensor and the center of a circle of a tire of the farm tractor are positioned in the same horizontal plane, and the width of the herringbone pattern on the surface of the tire and the interval between two adjacent herringbone patterns are obtained by measuring the difference of the time that laser reaches the tire of the farm tractor;
the control unit 3 is connected to the photoelectric sensor 2 and the motor 153 by signals, and is configured to:
the control part 3 judges whether the herringbone pattern exists in the contact area between the current wheel lower part and the soil according to the width of the herringbone pattern on the wheel surface of the farm tractor obtained by the photoelectric sensor 2 and the interval between two adjacent herringbone patterns:
when no manshaped pattern exists in the contact area between the lower part of the wheel and the soil, the compacted soil area below the wheel is a non-sunken area, the working depth of the long rake teeth 152 is too large, and extra resistance can be applied when the soil in the non-sunken area is loosened, the control part 3 controls the motor 154 to drive the rotating support 151 to rotate, and the short rake teeth 153 rotate to the position right below the wheel and enter the compacted soil, so that the resistance applied to the device is reduced while the soil compacted by the non-pattern area on the wheel can be loosened by the short rake teeth 153;
when the contact area between the lower part of the wheel and the soil has the humanoid pattern, which indicates that the soil area compacted under the wheel is a depressed area, the current working depth of the short rake teeth 153 cannot loosen the compacted soil in the depressed area in front, the control part 3 controls the motor 154 to drive the rotating bracket 152 to rotate, so that the long rake teeth 152 rotate to the position right below the depressed area to enter the compacted soil, the long rake teeth 152 can loosen the soil in the depressed area formed by the pattern compaction on the wheel, and the soil loosening effect of the device is better.
