Abstract
The utility model relates to a root cutting shovel of a maize harvester, which comprises a cutter shaft and cutter blades. Upper and lower two circular cutter blades are fixed on the cutter shaft. Each circular cutter blade is provided with a gap, or the circular edge of each circular cutter blade is provided with saw teeth which are uniformly protruded from the circular edge. The utility model has the advantages of reasonable structure, easy fabrication, small required power and traction force, low oil consumption, high work efficiency and stable work quality.
Description
The utility model relates to a kind of corn picker, and the root of cutting on particularly a kind of corn picker shovels.
The inventor once invented a kind of corn picker of returning crop stocks to the field, and (number of patent application: 99218006.6), the root shovel of cutting of this machine vertically is fixed on the knife rest, and the cutter point of a knife is downward, and cutter inserts high speed rotating in the ground during work, and corn root is blended.Though this root shovel cut is effective, required drive is big, and the energy consumption height because this grain header is matching used with 15-20 horsepower tractor with small four wheels, in case cutter is wrapped with things such as weeds, will rotates and dumbly even rotate, and causes the operation quality instability.
The purpose of this utility model will provide the little and well behaved corn picker of the low power of a kind of energy consumption simple in structure, required to cut the root shovel exactly, it can be under the condition that does not increase little four-wheel power steady operation.
For achieving the above object, the utility model adopts technical scheme as described below: a kind of corn picker is cut the root shovel, comprises cutter shaft and blade, is fixed with two cylinder blades up and down on the cutter shaft.
For sharp being convenient to of blade cut, gap is arranged on the cylinder blade, perhaps there is the sawtooth that evenly protrudes from outside the web on the circle limit of cylinder blade.
Adopt the corn picker of said structure to cut the root shovel, rational in infrastructure, be easy to make and change blade, required drive and tractive force are little, and oil consumption is few, high efficiency, operation quality is stable.
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model cylinder blade.
Fig. 3 is the structural representation of the another kind of cylinder blade of the utility model.
With reference to Fig. 1, Fig. 2, Fig. 3.A kind of corn picker is cut the root shovel, comprises cutter shaft 1 and blade 2, is fixed with two cylinder blades 2 up and down on the cutter shaft 1.This root shovel of cutting is installed in the following and straw pulverizing cutter coaxial rotation that straw is pulverized cutter.During work, cut root shovel root is cut off, the blade on upper strata is removed weeds and foreign material in order to avoid snarl and cut the root shovel, increases traction power, and blade is cut the root stump.For sharp being convenient to of blade cut, gap 3 is arranged on the cylinder blade, various types of gap such as V-arrangement, circular arc etc. all drop in the protection domain of the present utility model; Perhaps there is the sawtooth 4 that evenly protrudes from outside the web on the circle limit of cylinder blade, and various types of profile of tooth cylinder blades all drop within the protection domain of the present utility model.
