As shown in fig. 1 and fig. 2, the automatic adjusting device for the cutting length of the feed harvester comprises a feeding roller 1, a rotating speed sensor 2, a motor 3, a display 4, a button 5, a controller 6 and a variable pump 7; the feeding roller 1 comprises a plurality of upper feeding rollers 1 and a plurality of lower feeding rollers 1 which are symmetrically arranged, and the upper feeding rollers 1 and the lower feeding rollers 1 rotate in different directions under the driving of a motor 3; a rotating speed sensor 2 for measuring a rotating speed signal of the feeding roller 1 is arranged on the side of the feeding roller 1, the rotating speed sensor 2 measures the rotating speed signal of the feeding roller 1 and transmits data to a controller 6, the controller 6 compares the acquired data with a preset rotating speed value of the feeding roller 1, the controller 6 adjusts the rotating speed of the feeding roller 1 in real time by adjusting the displacement of a variable pump 7 so as to keep the rotating speed value of the feeding roller 1 at the preset rotating speed value of the feeding roller 1, and the preset rotating speed of the feeding roller 1 is completed through a display 4 arranged on the harvester; because the rotating speed value of the feeding roller 1 and the cut length of the feed are in a corresponding proportional relation, the cut length required by a user can be directly displayed on the display 4 of the harvester, and the user selects the preset rotating speed value of the feeding roller 1 after selecting the cut length.
When the rotation speed sensor 2 monitors that the rotation speed of the feeding roller 1 is higher than a preset rotation speed value of the feeding roller 1, the controller 6 controls a current signal value of the variable pump 7, the discharge capacity of the variable pump 7 is reduced by reducing the input current, the rotation speed of the feeding roller 1 is reduced along with the reduction of the discharge capacity of the variable pump 7, and when the rotation speed of the feeding roller 1 reaches the preset rotation speed value of the feeding roller 1, the controller 6 keeps the current signal value input to the variable pump 7 unchanged.

Further, the upper feeding roller 1 and the lower feeding roller 1 are driven by the same motor 3.
The working process of the invention is as follows:
the invention relates to an automatic adjusting device for the cutting length of a feed harvester, which mainly comprises the following steps in the automatic length control process:
1) System setting: under the setting state, the cutting length that the user needs when needing to set up the feed harvester during operation, this cutting length has corresponding feeding roller 1 rotational speed, feeding roller 1's rotational speed is by motor 3 rotational speed control, motor 3 rotational speed is again through variable pump 7's discharge capacity control, variable pump 7's discharge capacity is finally controlled through variable pump 7 input current value, consequently controller 6 only need according to the cutting length output that the user set for corresponding variable pump 7 electric current can, this electric current only is the primary current, follow-up needs are according to feeding roller 1's actual rotational speed automatic adjustment, in order to satisfy the cutting length who sets for. According to the actual requirement on the precision of the cut length of the feed, the interval of the cut length can be set to be 1mm, for example, the cut length is 5-20mm, and can be adjusted to be 5,6,7,8 to 20mm, so that the adjustment per millimeter is realized. The system stores the set value after the feed cutting length is set, and the feed cutting length set value is automatically used when the machine is started next time, so that the trouble that the cutting length is not changed and needs to be set is avoided.
2) Automatic adjustment of the cutting length: after the button 5 is pressed, an electric signal corresponding to the initial section length set by a user is transmitted to the controller 6, the controller 6 outputs current to the variable pump 7 according to the set section length, the variable pump 7 is driven to rotate by the hydraulic drive motor 3, and the motor 3 drives the feeding roller 1 to rotate, so that the feed section length meets the requirement. The controller 6 collects signals of the rotating speed sensor 2 once at certain intervals (such as 10 minutes), judges whether the rotating speed of the feeding roller 1 is within a set rotating speed range (such as +/-5%), does not adjust the output current of the controller 6 if the rotating speed is within the range, and adjusts the output current to enable the rotating speed of the feeding roller 1 to reach the set rotating speed range if the rotating speed is not within the range. Because the rotating speed of the feeding roller 1 is in corresponding relation with the feed cutting length, the feed cutting length corresponding to the rotating speed of the feeding roller 1 which is automatically adjusted to be within the set range is also within the set range.
