Abstract
A stalk pulverizing double-movable knife roll structure of a corn harvester belongs to an agricultural machine, a second movable knife roll assembly matched with a first movable knife roll assembly is mounted above the front side of the rear side of the first movable knife roll assembly at the position between an ejector roller and the first movable knife roll assembly, the rotation direction of the second movable knife roll assembly is opposite to the rotation direction of the first movable knife roll assembly. The stalk pulverizing double-movable knife roll structure effectively solves the problem that the corn harvester is blocked by the stalk in the work, and has the characteristics of reasonable and simple structure, good operation quality, high operation efficiency, less operation fault and reliable use.
Description
Technical field
The utility model belongs to agricultural machinery, relates generally to the broken operation structure of stalk powder on a kind of harvest corn facility.
Background technology
At present, the maize straw that has that uses in China's agricultural production is pulverized on the harvest corn facility of going back the field operation function, and mostly its stalk powder crushing device is to adopt one group of moving knife roller assembly and one group of stationary knife assembly to constitute, and configured in one piece is below corn draws the stem roller.During operation, draw the stem roller fast corn stem to be spurred downwards, and mandatory sending into carried out the broken operation of stalk powder in the stalk powder crushing device, in the actual job, because the stalk powder crushing device that moving knife roller and stationary knife are formed only has cane pulverizing function, draws the stem function poor, so draw between stem roller and the stalk powder crushing device through being everlasting plugging fault takes place, make facility normal operation continuously, reduced operating efficiency and operation quality.In the big plot of maize straw height, planting density, above-mentioned rate of breakdown is higher.
Summary of the invention
The purpose of this utility model is exactly the problem that exists at above-mentioned prior art, design provides a kind of maize harvesting machine stalk powder broken pair of moving knife roll structure, reaches minimizing and eliminates the purpose that the broken operation obstruction of stalk powder accident operating efficiency takes place, improves, guarantees operation quality.
Basic design of the present utility model is, broken pair of moving knife roll structure of a kind of maize harvesting machine stalk powder comprises and draws the stem roller and the first driving knife roller assembly, above the front side of the first driving knife roller assembly or back side top, drawing between stem roller and the first driving knife roller assembly position configuration that the second driving knife roller assembly that matches with the first driving knife roller assembly is installed, and the direction of rotation of the second driving knife roller assembly is opposite with the direction of rotation of the first driving knife roller assembly.
The utility model adopts the two moving knife roll structures that cooperatively interact, make the stalk powder crushing device only not possess the broken function of stalk powder, but also possesses the stem of drawing conveying function, efficiently solve maize harvesting machine stem stalk blockage problem, have the advantages that reasonable in design is simple, operation quality good, the operation fault is few, the use reliable, operating efficiency is high.
Description of drawings
Accompanying drawing is broken pair of moving knife roll structure of a maize harvesting machine stalk powder overall arrangement structural representation.
Piece number explanation among the figure:
1, draws stem roller, 2, the second driving knife roller assembly, 3, the first driving knife roller assembly.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the utility model is described in detail.Broken pair of moving knife roll structure of a kind of maize harvesting machine stalk powder comprises and draws the stem roller 1 and the first driving knife roller assembly 3, above the front side of the first driving knife roller assembly 3 or back side top, drawing between stem roller 1 and the first driving knife roller assembly 3 the position configuration that the second driving knife roller assembly 2 that matches with the first driving knife roller assembly 3 is installed, and the direction of rotation of the second driving knife roller assembly 2 is opposite with the direction of rotation of the first driving knife roller assembly 3.
During operation, corn stem enters to draw in the stem roller 1 and is spurred downwards fast, and mandatory sending between first and second opposite driving knife roller assembly 3 and 2 of direction of rotation pulverized throwing returning fast.Because the first driving knife roller assembly 3 and the second driving knife roller assembly 2 are the power drive rotor, and cooperatively interact, and maize straw is had the enforceable stem conveying function that draws, avoided the plugging fault generation herein of stem stalk.
Claims (1)
1. broken pair of moving knife roll structure of a maize harvesting machine stalk powder, comprise and draw the stem roller (1) and the first driving knife roller assembly (3), it is characterized in that in top, the front side of the first driving knife roller assembly (3) or back side top, be positioned at and draw the second driving knife roller assembly (2) that position configuration installation matches with the first driving knife roller assembly (3) between stem roller (1) and the first driving knife roller assembly (3), and the direction of rotation of the second driving knife roller assembly (2) is opposite with the direction of rotation of the first driving knife roller assembly (3).
