Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not delimit the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the invention without inventive step, are within the scope of the invention.
As shown in fig. 1 and 2, the present embodiment provides a spiral serrated cutter head suitable for cutting a water bamboo pier, including a cylindrical cutter holder 1, where the cylindrical cutter holder 1 is provided with a left half-side cutter group and a right half-side cutter group, each half-side cutter group includes a plurality of groups of serrated blade groups, and each group of serrated blade groups includes a plurality of serrated blades 2;
a plurality of groups of sawtooth blade groups of each half side blade group are distributed at equal intervals along the circumferential direction of the cylindrical blade holder 1, and a plurality of sawtooth blades 2 of each group of sawtooth blade groups are distributed at equal intervals along the axial direction of the cylindrical blade holder 1;
all the sawtooth blades 2 of each half side blade group are distributed on the cylindrical blade holder 1 in a spiral line, and a plurality of sawtooth blades 2 of two adjacent sawtooth blade groups are arranged in a staggered mode;
all the serrated blades 2 of the left half cutter set and all the serrated blades 2 of the right half cutter set are arranged in a left-right mirror image mode along the longitudinal section in the middle of the cylindrical cutter holder 1.
Wherein, the cylindrical cutter holder can be matched and connected with a rotary cultivator shaft through a rotating shaft.
As shown in fig. 3, on the basis of the above scheme, an offset angle a is provided between a point line of each serrated blade 2 on the cylindrical tool holder 1 and a longitudinal section (i.e., a forward direction) of the cylindrical tool holder 1, and the offset angle a may be 10 to 30 degrees. During the rotation and advance of the cylindrical cutter holder 1, the obliquely arranged sawtooth blades 2 have better effects of sawing and boosting soil turning.
Wherein the deflection angle is optimal when the deflection angle is in the range of 15-20 degrees.
As shown in fig. 4, on the basis of any of the above solutions, the plane of each serrated blade 2 on the cylindrical tool holder 1 and the axis of the cylindrical tool holder 1 are provided with an inclination angle B, and the inclination angle may be set to 45-60 degrees. The inclination angle B enables the cylinder cutter holder 1 to move forward in the rotary tillage process, the cutting edge of the serrated blade 2 can be downwards sawed, and meanwhile, the cutter face of the obliquely installed serrated blade 2 has a better soil turning effect.
On the basis of any scheme, all the sawtooth blades 2 of each half of the blade group are distributed on the cylindrical blade holder 1 in a single spiral or double spiral mode.
On the basis of any scheme, the shape of each single sawtooth of the sawtooth blade 2 is a straight line shape or a circular arc shape. The number of teeth of the sawteeth of the sawtooth blade 2 can be set to be 4-6, and all sawteeth on each sawtooth blade 2 are staggered and shifted left and right or staggered and shifted left, middle and right, so that the sawing function is achieved.
On the basis of any scheme, as shown in fig. 2, the sawtooth blade 2 is in a shape that the front end is low and the rear end is high, the bottom end of the front end tooth cutting edge is flush with the surface of the cylindrical cutter holder, and the whole cutting edge does not have a grass winding space in advance, so that the saw can be pushed to stably saw from shallow to deep step by step and can be prevented from winding.
The following is further explained in conjunction with the working principle:
the invention provides a spiral sawtooth-shaped cutter head suitable for cutting a water bamboo pier, wherein when the spiral sawtooth-shaped cutter head works, a cylindrical cutter holder 1 rolls forward to drive a sawtooth blade 2 to saw the water bamboo pier and turn soil simultaneously, and when the sawtooth blade performs saw cutting, the sawtooth blade firstly cuts a blade with a low front end downwards and then cuts a blade with a high rear end downwards due to the action of an inclination angle, so that the saw cutting from shallow to deep is formed, the saw cutting can be stable, and the winding can be prevented.
All the sawtooth blades are distributed on the cylindrical cutter holder in a spiral line, and are spirally distributed towards the left side of the left half-side cutter group, and meanwhile, all the sawtooth blades of the left half-side cutter group are inclined towards the left side by 15-20 degrees through the inclination angle, so that the sawtooth blades tend to shift towards the right when sawing and turning are carried out; for the right half cutter set, the right side is spirally distributed, and meanwhile, all the sawtooth blades of the right half cutter set incline rightwards for 15-20 degrees at the cylindrical cutter seat by the inclination angle, so that a left deviation trend is generated when sawing and turning soil are carried out; the deviation trends of the left side and the right side can be mutually offset, so that the stress of the cylindrical tool apron is balanced.
When sawing the water bamboo pier, because a plurality of sawtooth blade 2 of two sets of adjacent sawtooth blade group crisscross the setting each other, the sawtooth blade 2 of crisscross setting in-process of rotary tillage can prevent that massive water bamboo pier from being leaked and cut to can play the better effect of smashing the water bamboo pier, soil that simultaneously spirals out at the in-process of rotary tillage can leak down from between the sawtooth blade 2 of crisscross setting, and need not to discharge to one side, thereby make the field after the rotary tillage more even.
The invention is suitable for the wasteland reclaiming, rotary tillage and soil preparation, in particular to the operation of rotary tillage and cutting of cane shoot piers (the piers are large and deep, the toughness is good, and the common rotary tillage cutter is difficult to break) in the cane shoot field. The invention can also be matched with a small-sized management machine, is suitable for preparing the field of the cane shoots with greenhouse facilities and can also be matched with a medium-sized and large-sized rotary cultivator for operation.
The present invention is not limited to the above-mentioned alternative embodiments, and any other various products can be obtained by anyone in the light of the present invention, but any changes in the shape or structure thereof, all of which fall within the scope of the present invention, fall within the protection scope of the present invention.
