Ridge-top-sensing lifting device

Abstract

The invention relates to a ridge-top-sensing lifting device. The ridge-top-sensing lifting device comprises a sensing unit, an ECU control system, an oil cylinder driver, a lifting oil cylinder and acutter assembly and is characterized in that the sensing unit is arranged at the bottom of the cutter assembly and used for sensing the distance between the cutter assembly and the ridge top, the moving end of a lifting oil cylinder is connected with the cutter assembly and used for driving the cutter assembly to ascend and descend, the oil cylinder driver is connected with the lifting oil cylinder and used for driving the moving end of the lifting oil cylinder to telescope, the ECU control system is connected with the sensing unit and the oil cylinder driver and used for receiving the signalof the sensing unit and transmitting a telescoping signal to the oil cylinder driver according to the signal of the sensing unit so as to drive the moving end of the lifting oil cylinder to telescope.The ridge-top-sensing lifting device has the advantages that the height of the cutter relative to the ridge can be regulated, cutting height consistency can be guaranteed after the regulation, maximum sugarcane harvesting is achieved, small sugarcane harvesting loss rate is guaranteed, and perennial roots after the harvesting are good in germination rate the next year.

Description

technical field [0001] The invention relates to the field of agricultural machinery and equipment, in particular to a ridge height induction lifting device. Background technique [0002] Sugarcane is a perennial plant. Generally, sugarcane can be harvested continuously for three to four years once planted. China's sugarcane is mostly planted in the southern coastal provinces and cities or the southwest region. These areas are mostly mountainous and hilly basin landforms. The basins vary in size and the mountains are mostly arc-shaped. Even for some flat lands, due to irregular planting and soil cultivation, there are many sugarcane fields. Sudden bulges, depressions, sugarcane stumps, weeds, sugarcane leaves and other disturbances will also cause the final ridge height to be uneven, and general measurement methods cannot accurately and effectively measure the height of the tool from the ground. During the harvesting process of the traditional sugarcane harvester, the height...

China's sugarcane is mostly planted in the southern coastal provinces and cities or the southwest region. These areas are mostly mountainous and hilly basin landforms. The basins vary in size and the mountains are mostly arc-shaped. Even for some flat lands, due to irregular planting and soil cultivation, there are many sugarcane fields. Sudden bulges, depressions, sugarcane stumps, weeds, sugarcane leaves and other disturbances will also cause the final ridge height to be uneven, and general measurement methods cannot accurately and effectively measure the height of the tool from the ground

During the harvesting process of the traditional sugarcane harvester, the height of the root cutter head is artificially controlled so as not to penetrate too deep into the soil or leave the roots too high. Too deep will easily cause the sugarcane to be uprooted or directly damaged, resulting in a low germination rate or failure to germinate in the next year. It will also lead to the collection of sugarcane with a lot of soil, which will cause the collected sugarcane to have a high impurity rate and be too dirty. Too much resistance will cause the hydraulic system or mechanical mechanism controlling the cutter head to fail or the blade will be damaged; however, cutting too high will cause the part of the cut sugarcane above the ground to remain a lot, and this part of the sugarcane will be unharvestable. The loss is serious, and the part that is too high above the ground will also cause the germination rate of sugarcane to be greatly reduced in the coming year
