Description
Technical field
The utility model relates to a kind of cutting mechanics, particularly relates to the telescopic disc cutter of the soft long shoot stalk of a kind of suitable cutting.
Background technology
At present, the cutter on the market of a great variety, common type has three major types types such as reciprocating cutterbar, disk-blade cutter and flail knife formula cutter.Wherein reciprocating cutterbar is to use the widest a kind of cutter on the harvester for both rice and wheat both at home and abroad at present, existing basic standardization.It is made up of reciprocating cutter and fixed supporting part.Cutter is formed by the first-class riveted of knife bar, knife section and knife bar.The knife bar head is connected with transmission mechanism, in order to transmit the power of cutter.During work, cutter is done straight reciprocating motion, and its guard paracone is divided into tuftlet with cereal and guides cutter into, and cutter is pushed straw to stationary knife cutting at the volley.The average cutting speed of this cutter is lower, and cutting performance is good, and is simple in structure, and reliable operation is widely used on the corn mowing machine.Its shortcoming is that reciprocal inertia force is big, and ceding of Taiwan vibration and noise are big, and existence is heavily cut and leakage is cut, and it is irregular to cut stubble.Rotary cutting assembly is mainly used in thick stem stalk crops such as results herbage, green fodder, also uses this cutter on the minority grain harvesting machine.The rotary cutting assembly cutting speed is high, can adapt to the high speed operation, and inertia force is prone to balance, shake lessly, simple in structure, but the turning radius is little, and unsuitable wide cut is cut, and the life-span of cutter is shorter, the maintenance cost height.On grass harvester, adopt double plates more or organize double plate more, each cutterhead send grass dish and group careless drum etc. to form by cutterhead frame, blade, taper.Single-deck and the double plates that adopt on cane harvester with trapezoidal or rectangle fixed blade more.On the small-sized rice grain header, often adopt single-deck and polydisc cluster type.Flail knife formula disc cutter is used on the corn Silage grain header more, adopts flail knife formula disc cutters on the grain header both at home and abroad at present more.It is made up of cutter axis, cutter head, blade and guard shield etc.The blade pin is connected on the cutterhead, revolution in vertical plane (parallel with direction of advance).This cutter rotating speed is high, but swath is narrower, and on the bigger machine of swath, adopt organized parallel-connection structures more more.
Although it is so, China is being studied aspect the grass crop harvesting machineryization very early, but majority is the grass harvester tool that is used for pastoral area, northern grassland, just begins for the research of southern seat grass type straw harvesting mechanization.Because the harvesting of seat grass is seasonal by force, the time is short, the amount of labour is big,, will cause the lodging of seat grass to be rotted and the underproduction in maturing stage such as untimely harvesting.Seat grass blade bar is elongated and smooth, rounded, and diameter is little, and is different in size, adopt traditional approach to be difficult to realize mechanized harvest, and it is too high to cut stubble, influences crop.
The utility model content
The technical problem that the utility model solved is to provide the telescopic disc cutter of the soft long shoot stalk harvesting of a kind of suitable harvesting, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solved adopts following technical scheme to realize:
The telescopic disc cutter that is fit to soft long stalk; Comprise cutter shaft, carriage set bolt, cutterhead carriage, upper tool pan, upper tool pan lining lid, following cutterhead, following cutterhead set bolt, tight fixed bolt, blade pin, blade, upper tool pan set bolt; Said cutterhead carriage is fixed on the cutter shaft through the carriage set bolt, and said upper tool pan and upper tool pan lining lid are fixed on the cutterhead carriage through the upper tool pan set bolt, and said blade is connected between upper tool pan and the upper tool pan lining lid through the blade pin; Blade and blade pin matched in clearance; Said down cutterhead is fixed on the end of cutter shaft through tight fixed bolt, is fixed on the cutterhead carriage with time cutterhead set bolt again, and said upper tool pan is the truncated cones tube; Said blade pin is attached on the upper tool pan conical surface, with the angle on ground be 20 °.
During the utility model work, upper tool pan rotates with cutter shaft with following cutterhead, and the blade that stretches in cutterhead is thrown away by centrifugal force; Material there is not the support high-speed cutting; If blade is broken or when flying out cutterhead, can in than short distance, insert in the soil, avoid the accident of meeting accident.
Beneficial effect: the utility model is simple in structure, and handling safety is reliable.

Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
The telescopic disc cutter that is fit to soft long stalk; Comprise that cutter shaft 1, carriage set bolt 2, cutterhead carriage 3, upper tool pan 4, upper tool pan lining cover 5, play cutterhead 6, play cutterhead set bolt 7, tight fixed bolt 8, blade pin 9, blade 10, upper tool pan set bolt 11; Said cutterhead carriage 3 is fixed on the cutter shaft 1 through carriage set bolt 2; Said upper tool pan 4 and upper tool pan lining covers 5 and are fixed on the cutterhead carriage 3 through upper tool pan set bolt 11, and said blade 10 is connected upper tool pan 4 through blade pin 9 and the upper tool pan lining covers between 5, blade 10 and blade pin 9 matched in clearance; When not working, in the scalable feed dish of blade; Said down cutterhead 6 is fixed on the end of cutter shaft 1 through tight fixed bolt 8, is fixed on the cutterhead carriage 3 with time cutterhead set bolt 7 again, and said upper tool pan 4 is the truncated cones tube, and said blade pin 9 is attached on upper tool pan 4 conical surfaces, with the angle on ground be 20 °.
In the utility model when work,, upper tool pan 4 rotates with cutter shaft 1 with play cutterhead 6, and blade 10 is thrown away by centrifugal force; Material there is not the support high-speed cutting; If blade 10 is broken or when flying out cutterhead, can in than short distance, insert in the soil, avoid the accident of meeting accident.
