Abstract

Chopping formula stalk reducing mechanism is cut to maize picker header, arbor (5) are located maize picker header below to with disc (4) center cartridge cooperation, cutter arm (2) link firmly through bolt (3) with disc (4), with the centre of a circle of disc (4) install 2 cutter arms (2) for the center of symmetry, along the axis direction equidistance rigid coupling N blade (1) of cutter arm (2), the distance of adjacent blade (1) is 10mm, blade (1) shape is isosceles triangle, isosceles triangle blade (1) base and cutter arm (2) laminating and blade (1) whole and cutter arm (2) surface vertical during the installation, simultaneously in device rotation process blade (1) summit is unanimous rather than linear velocity direction. The invention has simple and reasonable structure, novelty, practicability and good operation effect.

Description

Cutting table chopping type stalk crushing device of corn harvester

Technical Field

The utility model belongs to agricultural machinery mainly relates to a maize stalk crushing operation device.

Background

A flail type stalk crushing device below a cutting table of an existing corn harvester adopts a crushing knife to transversely cut corn stalks to complete crushing operation. In the practice of production operation and use, because the physical strength of the hardened corn straw outer skin layer fibers is very high, the crushing effect of crushing the corn straws by a single transverse cutting is poor, the fine crushing degree is low, a lot of difficulties are brought to crushing, returning and fertilizing the soil fertility of the corn straws or preparing organic fertilizers, and the decomposition and fermentation time is long.

Disclosure of Invention

The utility model discloses an aim at exactly to the problem that above-mentioned prior art exists, combine the actual need of maize straw crushing operation, design a maize picker header cuts split formula stem stalk reducing mechanism, reach maize straw crushing effectual, the high quality, be favorable to the maize straw after smashing still field rotten or conveniently prepare the purpose that the organic fertilizer used.

The purpose of the utility model is realized like this: the utility model provides a maize picker header cuts formula stalk reducing mechanism of cleaving, it mainly comprises spare parts such as arbor, disc, sword arm, bolt, blade, its characterized in that: the arbor is located maize picker header below to with the cooperation of disc center cartridge, the tool arm links firmly through the bolt with the disc, with the centre of a circle of disc for 2 tool arms of centre of symmetry installation, along the axis direction equidistance rigid coupling N blades of tool arm, the distance of adjacent blade is 10mm, the blade shape is isosceles triangle, isosceles triangle blade base and tool arm laminating and blade are whole and tool arm surface vertical during the installation, simultaneously in the rotatory in-process blade summit of device is unanimous rather than linear velocity direction.

The utility model discloses the formula stalk reducing mechanism is cut to maize picker header that belongs to installs in harvester header below, can increase the percentage of damage of operation back maize stalk, smashes still field fast for maize stalk and rot to bank up fertile land fertility and provide support, also can provide high-quality raw materials for fertilizer production. The device has the characteristics of novel, unique and reasonable structure, good crushing operation quality, high efficiency, strong applicability and reliable use.

Detailed Description

The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Chopping formula stem stalk reducing mechanism is cut to maize picker header, it mainly comprises spare parts such as blade 1, arm of a knife 2, bolt 3, disc 4, arbor 5, its characterized in that: the cutter shaft 5 is fixedly connected with the disc 4, so that the stalk crushing device is matched with the header. The disc 4 is connected with the cutter arm 2 through a bolt 3, N blades 1 which are in isosceles triangle shapes are installed on the cutter arm 2 along the axis direction, the blades 1 are perpendicular to the surface of the cutter arm 2, and the vertex of each blade 1 is consistent with the linear velocity direction of the blade 1 when the blade rotates.

During operation, the corn harvester drives the whole stalk crushing device to rotate through the rotation of the cutter shaft 5 in the advancing process, corn stalks continuously move downwards under the action of the stalk pulling roller, and when the stalks enter the working range of the crushing device, the stalks are split by the blade moving at a high speed along the axial direction of the stalks, so that the stalks are crushed into narrow strips to be scattered to the field.

Claims (1)

1. Chopping formula stem stalk reducing mechanism is cut to maize picker header, its characterized in that: arbor (5) are located maize picker header below to with disc (4) center cartridge cooperation, arm (2) link firmly through bolt (3) with disc (4), with the centre of a circle of disc (4) install 2 arm (2) for the center of symmetry, along the axis direction equidistance rigid coupling N blade (1) of arm (2), the distance of adjacent blade (1) is 10mm, blade (1) shape is isosceles triangle, isosceles triangle blade (1) base and arm (2) laminating and blade (1) are whole and arm (2) surface vertical during the installation, and simultaneously blade (1) summit is unanimous rather than linear velocity direction at device rotation in-process.
