Embodiment Construction

[0026] The specific implementation manner of the present invention will be described in detail below in conjunction with specific examples.

[0027] like Figure 1-2 As shown, the present invention discloses a crop stalk stubble cutting device, which includes a linkage mechanism and a cutter head 13, the linkage mechanism is a four-bar linkage mechanism 1, and the four-bar linkage mechanism 1 is fixedly connected to the frame beam through a U-shaped card. .

[0028] like Figure 3-4 As shown, the cutterhead 3 is a circular arc surface structure with a circular outer edge, and the cutterhead 13 is two pieces, with the convex faces facing outwards. Each cutterhead 13 is connected with the four-bar linkage mechanism 1 through a connecting assembly, and the connecting assembly Including connecting rod 4 and connecting arm 5, one end of connecting rod 4 is fixedly connected with four-bar linkage mechanism 1 through bolt 2 and sleeve 3, and the other end is fixedly connected with ...

Abstract

The invention discloses a crop straw stubble cutting-off device. The crop straw stubble cutting-off device comprises a linkage mechanism and cutter heads, two pieces of the cutter heads are arranged, each piece of the cutter head is connected with the linkage mechanism through a connecting assembly, each cutter head is axially and fixedly provided with a rotating shaft, the rotating shaft is connected with the corresponding connecting assembly through a bearing pedestal arranged outside the rotating shaft, the two pieces of the cutter heads have a certain included angle, and the closest positions of the edges of the two pieces of the cutter heads are the lowest positions of the edges of the cutter heads. The crop straw stubble cutting-off device is scientific and reasonable in structural design; compared with the prior art, the crop straw stubble cutting-off device is advantaged in that the device is novel in structure, does not need to be driven by a power take-off shaft of a tractor and only needs to be pulled by the tractor to move ahead, the cutter heads can cut off crop straw stubble; and the device is high in cutting-off rate. When the crop straw stubble cutting-off device works, because crop straw is between two cutter heads, after the stubble is cut off, the crop straw is arranged longitudinally and relatively tidily, and can be picked up for use conveniently.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery and equipment, in particular to a crop straw stubble cutting device. Background technique [0002] In recent years, with the improvement of crop production level and multiple cropping index and the popularization and application of coal gas and natural gas in rural areas, the phenomenon of absolute surplus of straw has become more prominent. According to relevant statistics, more than 700 million tons of straw can be produced in my country every year. Straws are discarded randomly and burned seriously, which brings a series of problems such as air pollution, serious waste of resources, damage to soil structure, and endangers sustainable agricultural development. Accelerating the comprehensive utilization of straw is of great significance for improving the comprehensive utilization of agricultural resources and reducing environmental pressure. The ways of comprehensive utilization o...
