The invention discloses a feed quantity control device and method of a sugarcane harvester. The device comprises a pressure sensor, induction blocks, Hall sensors, an electric-hydraulic proportional flow valve and a PLC. The pressure sensor is installed on an inlet of a hydraulic motor of a sugarcane pressing roller and used for collecting loading pressure signals. The induction blocks are arranged on the edges of hubs of wheels. Each Hall sensor is arranged on one side of the corresponding induction block, and the Hall sensors are used for collecting the rotation speed of the wheels through the induction blocks. The electric-hydraulic proportional flow valve is used for controlling the traveling speed of the wheels of the sugarcane harvester. The input end of the PLC is connected with the pressure sensor and the Hall sensors, the output end of the PLC is connected with the electric-hydraulic proportional flow valve, and the PLC is used for obtaining the normal rotation speed of the wheels. When the loading pressure sensors exceed a preset value, the rotation speed of the wheels is controlled to be lower than the normal rotation speed. When the loading pressure sensors lower than the preset value, the rotation speed of the wheels is controlled to be the normal rotation speed. By detecting the feed quantity and the traveling speed in real time, feedback control of the feed quantity is achieved, the situation that the feed quantity is too large and accordingly a logistics channel is blocked is avoided, and work efficiency and sugarcane cutting quality are guaranteed.

The invention discloses a method for controlling rotational speed of an engine generator, belonging to the technical field of engine generators. The method comprises the following steps: obtaining an n-IA1 curve graph, an n-IA2 curve graph, an n-DCLV curve graph and a DCLV-n curve graph according to an open loop characteristic curve of the generator; judging whether a current work region of the generator is a saturated region, a transition region or a linear region and judging a 1.1-time DCLV work region; outputting a target rotational speed of the generator through a dynamic discretization method if the work region of the generator is the saturated region or the transition region; and keeping the target rotational speed of the generator unchanged if the work region of the generator is the linear region. According to the method for controlling the rotational speed of the engine generator, the target rotational speed of the generator is adjusted by judging the working state of the generator and output through the dynamic discretization method so that the response capacity of the direct-current output voltage of the generator is ensured and the service life of the generator is prolonged, and therefore, the generator can work in a more efficient state.
