Abstract

An interlaced straw cutter head of a cutter tool comprises a main shaft, a left knife rest, a right knife rest and a cutting knife. The technical proposal is as follows: the left knife rest is installed on the left side of the main shaft; the right knife rest is installed on the right side of the main shaft; and the cutting knife is installed on the ridge surface of the knife rests. The interlaced straw cutter head effectively reduces the manufacturing and cutter sharpening difficulty, reduces the gap on the middle part of the edge, reduces cutting resistance, improves cutting efficiency and has better cutting efficiency.

Description

Cutter alternating expression stalks cutting device

Technical field

The utility model relates to a kind of stalk cutter (hay cutter) chopper device that is used for, especially a kind of cutter alternating expression stalks cutting device.

Background technology

At present, the cutting knife of installing on stalk cutter (hay cutter) chopper mostly is a whole long piece, its manufacturing and sharpening be difficulty quite, cylinder type cutterhead particularly, the gap of its assembling cutting knife two ends, back and stationary knife transfers to when requiring, its cutting edge mid portion has very big gap, because blade cutting edge is close to simultaneously stressedly, its chopping resistance is big during work.

The utility model content

In order to overcome existing stalk cutter (hay cutter) cutting knife sharpening difficulty, assemblage gap inequality, the big deficiency that waits of cutting resistance, the utility model provides a kind of cutter alternating expression stalks cutting device, not only the blade manufacturing is simple, and assemblage gap is even, and can effectively reduce to cut resistance.

The utility model is that chopper is decomposed into two or more sets knife rests, and each is organized, and knife rest is staggered to be installed, and integral body one long piece cutting knife is become on the knife rest after two or more shortened cutting blades are installed in decomposition; Specifically be made up of main shaft (1), left knife rest (2), right knife rest (3), cutting knife (4), its technical scheme is that main shaft (1) left side is equipped with left knife rest (2), and main shaft (1) right side is equipped with right knife rest (3), on the outer faceted pebble of knife rest cutting knife (4) is housed.

Its beneficial effect is the difficulty that has reduced manufacturing and sharpening effectively, has reduced the gap of cutting edge mid portion, has reduced the chopping resistance, has improved shredding efficiency, and the chopping effect is better.

Description of drawings

Below in conjunction with accompanying drawing the utility model is described in further detail

Fig. 1 is a general assembly structural representation of the present utility model.

Fig. 2 is a cutter structure schematic diagram of the present utility model.

Among the figure, main shaft (1), left knife rest (2), right knife rest (3), cutting knife (4).

Embodiment

As depicted in figs. 1 and 2, the utility model is made up of main shaft (1), left knife rest (2), right knife rest (3), cutting knife (4), its technical scheme is that main shaft (1) left side is equipped with left knife rest (2), main shaft (1) right side is equipped with right knife rest (3), on the outer faceted pebble of knife rest cutting knife (4) is housed, constitutes cutter alternating expression stalks cutting device described in the utility model.

Claims

1. cutter alternating expression stalks cutting device, form by main shaft (1), left knife rest (2), right knife rest (3), cutting knife (4), it is characterized in that: a side of main shaft (1) is equipped with left knife rest (2), main shaft (1) opposite side is equipped with right knife rest (3), on the outer faceted pebble of knife rest cutting knife (4) is housed, thereby constitutes a kind of cutter alternating expression stalks cutting device described in the utility model.

2. cutter alternating expression stalks cutting device according to claim 1 is characterized in that: the installation direction of wherein said left knife rest (2) on main shaft (1) is provided with angle with respect to right knife rest (3) rotation.

3. cutter alternating expression stalks cutting device according to claim 1 is characterized in that: wherein said cutting knife (4) cutting edge with tilt with respect to the alignment of shafts, be provided with angle.
