Abstract
The utility model discloses an automatic chip cutting device of a harvester. A chip cutting knife is arranged on the end head of a threshing roller. A chip cutting plate is movably fixed on a chip outlet. The distance between an edge of the chip cutting plate and the chip cutting knife is from 0.01 to 2 mm. An adjustable screw can adjust the distance between the edge of the chip cutting plate and the chip cutting knife. When a harvester works, the chip cutting knife is matched with the edge of the chip cutting plate, stalks stacked on the chip outlet are cut off and the accumulation of the stalks on the chip outlet can be prevented. The utility model has simple and practical structure and can effectively improve the work performance of harvesters.
Description
Technical field
The utility model relates to a kind of grain header, specifically relates to the automatic chip breaking device of a kind of grain header.
Background technology
Known grain header has the straw of employing side to go out the bits mode, straw after the threshing is dished out by the side crumb mouth, but often exist a small amount of straw to pile up in the crumb mouth, need artificial removing in time, otherwise straw can further be piled up and twine threshing roll and rotating shaft, increasing grain header load reduces harvesting efficiency, damages sheller unit.
Summary of the invention
The utility model aims to provide the automatic chip breaking of a kind of energy, prevents the automatic chip breaking device of grain header that straw is piled up in the crumb mouth.
The technical solution adopted in the utility model is: the chip breaking cutter is installed in the termination at threshing roll, and the chip breaking plate is installed in the crumb mouth.
The activity of described chip breaking plate is fixed on the crumb mouth, chip breaking plate cutting edge inwardly stretches into, with the chip breaking cutter at a distance of 0.01-2mm, best at 0.1-1mm, during grain header work, the chip breaking cutter of rotation can cooperate with the chip breaking plate, at chip breaking plate cutting edge place the straw of storing up is cut off, dish out with the crumb mouth air-flow in straw top after the cut-out, the lower part drops in the threshing tube again, stopped straw at the crumb mouth packing phenomenon.
Described chip breaking plate one end is movable fixing, and the other end is equipped with adjustable dog screw, can regulate the spacing of chip breaking plate and chip breaking cutter according to the practical application needs, to reach best chip breaking effect.
Described chip breaking cutter is installed in threshing roll near the termination, crumb mouth, can install more than one or one according to the practical application needs.Chip breaking knife-edge shape can be triangle, rectangle or other shapes, in order to improve the chip breaking effect, can be on the chip breaking limit uniform sickle tooth.Two sides of chip breaking cutter also can all uniform sickle tooth, so that after the working face wearing and tearing, and the replacement working face that can overturn, prolongation chip breaking cutter service life.
The beneficial effect that the utility model produces has: 1, chip breaking automatically, prevent that straw from piling up in the crumb mouth, and solve straw effectively and twined a difficult problem.2, simple and practical, help improving the transaction capabilities of harvesting.

Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
Among Fig. 1,2 activities of chip breaking plate are fixed on crumb mouth 1, and cutting edge 3 inwardly stretches into, chip breaking cutter 4 is fixed on the termination of threshing roll 5, chip breaking cutter 4 and cutting edge 3 spacing 0.1-1mm, when grain header was worked, chip breaking cutter 4 was in company with threshing roll 5 rotations, through cutting edge 3 be, can cooperate with cutting edge 3, the straw that crumb mouth 1 is stored up cuts off, and dishes out with the air-flow of crumb mouth 1 outside the machine in the straw top after the cut-out, the lower part drops in the threshing tube again, has prevented the packing phenomenon of straw in the crumb mouth effectively.Among Fig. 2, the 2 one end activities of chip breaking plate are fixed on the crumb mouth 1, and the other end is fixed on activity on the crumb mouth 1 by expansion screw 6, regulate expansion screw 6, just can regulate the spacing of cutting edge 3 and chip breaking cutter 4, to adapt to the operation needs, reach best chip breaking effect.
