Embodiment 1

[0023] Embodiment 1, the present invention is an automatic driving real-time control liquid fertilizer jet hole fertilizer machine, including a small crawler tractor 1, and the small crawler tractor 1 can independently select the manual traction in the prior art or the autonomous traction that can realize automatic driving. Selected as the prior art, the main improvement point is that a machine tool 2 is connected to the right side of the small crawler tractor 1. The machine tool 2 includes two frames 3, and the frames 3 are placed at the right end of the machine tool 2. The end is rotatably connected with a rotating rod 4, the two rotating rods 4 are connected by a cross rod 5, a fixed block 6 is sleeved on the cross rod 5, and an electric telescopic cylinder 7 is installed above the fixed block 6, and the telescopic cylinder 7 Controlled by the control box 37 or installed with a telescopic rod, which requires manual control, the telescopic cylinder 7 is rotated and installed ...

Embodiment 2

[0037] In the second embodiment, a GPS vehicle-mounted mobile station 39 is installed on the upper right end of the small crawler tractor 1, and a GPS reference station 40 is installed at the operating point, which refers to the end of the farmland during operation.

[0038] The GPS reference station 40 and the GPS vehicle-mounted mobile station 39 of the present invention constitute an automatic driving system. The liquid fertilizer pump 36 is connected with the liquid fertilizer tank 35 and the solenoid valve 34 and the fertilizer spray needle 32 to form a fertilizer spray system. The valve 34, the solenoid valve 34 is connected with the fertilizer spray needle 32 through the fertilizer delivery pipe 33, and the solenoid valve 34 is connected with the control box 37 through the wire. Before the machine tool 2 operates, the GPS reference station 40 needs to be installed in an open place near the work site. After the installation is completed, the staff needs to manually input ...

Embodiment 3

[0040] In the third embodiment, the control of the solenoid valve 34, the laser sensor 38, and the liquid fertilizer pump 36 all need to be controlled by the single-chip microcomputer in the control box 37. The following is the control circuit diagram of the single-chip microcomputer. The pin 1 of the diode D2 is connected to the negative pole of the diode D2, the relay K1, and the pin 37 of the microcontroller. The positive level of the diode D2 and the relay K1 are connected to the ground GND. One end of the relay K1 is connected to the pin 2 of the solenoid valve, and the pin 1 of the solenoid valve is connected to the power supply. VCC and the positive pole of the polar capacitor C4, and the other end of the polar capacitor C4 is grounded to GND.

[0041] The pin 10 of the microcontroller is connected to the negative electrode of the polar capacitor C5 with a capacitance of 10uF, the positive electrode of the polar capacitor C5 is connected to the power supply VCC and the s...

Abstract

The invention is an automatic driving real-time control liquid fertilizer jet hole fertilization machine, which effectively solves the technical problem that the needle body is easily blocked during the fertilization process, and the needle body posture cannot be adjusted in real time. It includes a small crawler tractor connected with an organic implement , the implement includes a rotating rod, a first sprocket and a second sprocket are installed at both ends of a rotating rod, the output shaft sleeve is provided with a ground wheel, the first sprocket is connected with a first rotating shaft, and there is a first cone on the first rotating shaft Gears, the first bevel gear is meshed with a mechanical speed measuring device, the mechanical speed measuring device is connected with a fertilizer spraying needle, the fertilizer spraying needle is connected with a solenoid valve, the solenoid valve is connected to a liquid fertilizer tank, the liquid fertilizer tank is connected to a liquid fertilizer pump, and a control box is installed on the left side of the liquid fertilizer tank. The invention detects the forward speed of the operation through the mechanical speed measuring device, adjusts the fertilizer spraying angle of the fertilizer spraying needle in real time through the mechanical speed measuring device, realizes that the jet flow angle is basically unchanged during the operation process, avoids the soil blockage of the fertilizer spraying needle, and realizes the goal of a small area of ​​fertilizer .

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an automatic driving real-time control of a liquid fertilizer jet hole fertilizer applicator. Background technique [0002] The liquid fertilizer hole applicator is a work tool that applies liquid fertilizer holes to the roots of crops. Most of the existing liquid fertilizer applicators adopt the traction method and combine with the spraying needle to pierce the hole to realize the deep application of liquid fertilizer. The goal of small fertilizer area cannot be achieved, and the machine cannot realize automatic driving. [0003] On this basis, the present invention provides an automatic driving real-time regulation and control of liquid fertilizer jet hole fertilizer machine. SUMMARY OF THE INVENTION [0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides an automatic driving real-time control...
