6. The small walking sugarcane fine cutting machine according to claim 5, wherein one end of the cutting shaft vertically penetrates through the first adjusting plate to be connected with the bevel gear transmission system, and the other end of the cutting shaft is connected with the cutting knife.
7. The small walk-behind sugarcane harvester according to claim 2, wherein the guide plate is a plate-like structure that pushes the sugarcane cut by the cutter blade down toward both sides of the advancing direction of the harvester during operation of the harvester.
8. The miniature walk behind sugarcane harvester of claim 1, wherein the frame has a width of 0.5-1.3 m; the width of the guide plate is 1.3-2 m;
a handrail and a traction hole are arranged at the rear part of the frame;
the handrail is provided with a control button for manually adjusting the inclination angles of the first adjusting plate and the second adjusting plate.
9. A method of controlling a small walk-behind sugarcane top harvester according to any one of claims 1 to 8, the method comprising:
a control button directly sends a control instruction to the controller to control the first telescopic rod and the second telescopic rod to stretch and contract, so that the first adjusting plate drives the cutting part to incline left and right;
and/or directly sending a control command to the controller by a control button to control the third telescopic rod and the fourth telescopic rod to stretch and retract, so that the second adjusting plate drives the guide plate to incline left and right.
10. A method of controlling a small walk-behind sugarcane top harvester according to any one of claims 1 to 8, the method comprising:
step 1: before the fine cutting machine works, calibrating the initial angle values of the first angle sensor and the second angle sensor;
step 2: setting target values of angles measured by the first angle sensor and the second angle sensor in the control terminal according to actual operation requirements;
and step 3: during operation, the control terminal receives the angle values measured by the first angle sensor and the second angle sensor in real time and judges whether the measured angle values are matched with a target angle value or not;
and 4, step 4: if the measured angle value is matched with the target angle value, the control terminal does not send a control instruction to the controller, and the first adjusting plate and the second adjusting plate keep the current state;
and 5: if the measured angle value is not matched with the target angle value, the control terminal sends a control instruction to the controller, and the controller controls the first telescopic rod and the second telescopic rod to stretch and retract, so that the first adjusting plate drives the cutting part to incline left and right;
and/or the controller controls the third telescopic rod and the fourth telescopic rod to stretch and retract, so that the second adjusting plate drives the guide plate to incline left and right;
step 6: the first angle sensor on the first adjusting plate and/or the second angle sensor on the second adjusting plate feed back the current measurement angle value to the control terminal, and the control terminal judges whether the current measurement angle value is matched with the target angle value or not to complete a control cycle.
