Tip cutting device of sugarcane harvesting machine

Abstract

The invention relates to a tip cutting device of a sugarcane harvesting machine. The tip cutting device comprises guiding barrels, a telescopic drive device and a tip cutting mechanism, wherein the outer wall of each guiding barrel is provided with a plurality of projections and a plurality of first cutting blades, the quantity of the guiding barrels is two, and the first guiding barrel and the second guiding barrel are symmetric to each other; the telescopic drive device comprises a guide rod and a loop bar which is matched with the guide rod and is horizontally arranged, the end part of a first guide rod of a first telescopic drive device and the end part of a second guide rod of a second telescopic drive device are respectively connected with a baffle plate, and the cross section of the arrangement of the two baffle plates is in a V-shaped structure; the tip cutting mechanism is arranged between the two baffle plates, the edge of a tip cutting disc is provided with a plurality of second tip cutting blades, one end of each tip cutting blade is provided with a distance adjusting device and connected with the tip cutting disc, and the tip cutting disc is connected with a longitudinal adjusting device. By adopting the tip cutting device of the sugarcane harvesting machine, the distance between the tip cutting parts is adjusted according to the harvesting situation of a sugarcane field, the impurity content can be effectively reduced, and the sugarcane quality is improved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a tip cutting device of a sugarcane harvester. Background technique [0002] Sugarcane is usually planted in multiple rows, and there is a certain row spacing between every two rows of sugarcane. This row spacing will vary with the geographical environment and planting habits of each place. On the other hand, the sugarcane harvester needs to change rows frequently when working. Due to the long support of the tip-cutting mechanism of the domestic sugarcane harvester, the sugarcane harvester has poor flexibility when changing lines, and even cannot change lines. [0003] In the sugarcane harvesters widely used at present, the tip cutting mechanism of the sugarcane harvester is controlled by a hydraulic system, and the distance between the tip cutters is fixed, while the sugarcane line spacing on the harvesting site usually fluctuates to a certain extent.

[0002] Sugarcane is usually planted in multiple rows, and there is a certain row spacing between every two rows of sugarcane. This row spacing will vary with the geographical environment and planting habits of each place. On the other hand, the sugarcane harvester needs to change rows frequently when working. Due to the long support of the tip cutting mechanism of the domestic sugarcane harvester, the flexibility of the sugarcane harvester when changing lines is poor, or even unable to change lines

[0003] In the sugarcane harvesters widely used at present, the tip cutting mechanism of the sugarcane harvester is controlled by a hydraulic system, and the distance between the tip cutters is fixed, while the sugarcane line spacing on the harvesting site usually fluctuates to a certain extent. When there is a large difference between the distance between rows and the row spacing of sugarcane, part of the sugarcane cannot be trimmed and needs to be reworked, the efficiency of tip cutting is poor, and the impurity content is high, which affects the quality of sucrose
