Embodiment Construction

[0034] The following is attached Figure 1-3 The present invention is described in further detail.

[0035] Such as figure 1 As shown, the sugarcane harvester cutterhead profiling cutting platform is mainly divided into a cutterhead lifting system, a cutterhead drive system, a cutterhead height automatic adjustment control system and a frame 15;

[0036] The cutterhead lifting system is arranged on the two longitudinal beams at the front end of the frame 15; the cutterhead drive system is arranged on the bottom crossbeam of the frame 15 and is located at the rear end of the frame 15; the cutterhead height is automatically adjusted Control system is arranged on the right crossbeam of frame 15 obliquely.

[0037] The cutterhead lifting system includes: cutterhead cutting frame 3, two linear slide rails 2, profiling rod 7, profiling wheel 8, cutterhead shaft 9, cutterhead 10, right-angle steering gear 4 and elastic coupling 5 ;

[0038] The two linear slide rails 2 are respec...

Abstract

The invention relates to a copying cutting platform for a cutterhead of a sugarcane harvester. The platform comprises a cutterhead lifting system, a cutterhead driving system, a cutterhead height automatic adjusting control system and a rack. The cutterhead lifting system is arranged on two longitudinal beams at the front end of the rack. The cutterhead driving system is arranged on a bottom cross beam of the rack and is positioned at the rear end of the rack. The cutterhead height automatic adjusting control system is arranged on an inclined right cross beam of the rack. According to the platform, an angle sensor is adopted to measure the relative angle of a copying wheel and a copying rod, a controller calculates the actual height of the cutterhead through a cutterhead height mathematical model, then an electromagnetic reversing valve is controlled to be switched on and switched off, a hydraulic cylinder is controlled to stretch out and draw back, and the purpose of controlling the cutterhead height in real time is achieved. The hydraulic cylinder is used for automatically adjusting the height of the cutterhead instead of manual adjustment, the accuracy of the height of the cutterhead is greatly improved, and harvesting loss and sugarcane head breaking can be reduced. The platform is simple in structure, low in manufacturing cost, convenient to repair and maintain and high in practicability.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a profiling cutting platform for a cutter head of a sugarcane harvester. Background technique [0002] In China, sugar cane is an important raw material for the sugar industry. Sugarcane planting area accounts for 85% of China's sugar crop planting area. In Brazil and other countries, sugarcane is also an important raw material for bioethanol and biomass power generation, and sugarcane production has become an important factor for the country to regulate the proportion of energy. In China, sugarcane is mainly grown in southern tropical regions such as Guangxi, Guangdong, and Yunnan, which are all jagged sugarcane fields. During the harvesting process, the machine operator can only manually adjust the height of the cutter head. If the cutter head is set too high, cane loss and broken ends will increase. Conversely, if the knife head is set too low, i...
