Abstract
The utility model discloses a draw stem roller, including the blade, it is epaxial that the blade is fixed in the intervalve through threaded fastener, still including the clamp plate that has the kink, the clamp plate cover is established threaded fastener is last, and the cramping in the blade with between threaded fastener's the fixing head. The utility model discloses not only can improve and draw the stem effect, make the blade atress on the draw stem roller even moreover, prolong the life of blade.
Description
Technical field
This utility model relates to maize harvesting machine technical field, particularly relates to the stem pulling on a kind of maize harvesting machine
Roller.
Background technology
The work process of the stem pulling roller on maize harvesting machine is to clamp corn stem to pull down, until Semen Maydis
Fruit ear is removed and corn stem is continuous, it is achieved harvesting.
At present in maize harvesting machine the parts of the stem pulling part of stem pulling roller consist of intermediate tubular shaft, blade and
Fastening bolt, blade is fixed on intermediate tubular shaft by fastening bolt.During work, a pair stem pulling roller coordinates,
Two stem pulling roller opposite direction rotatings, the knife register of two stem pulling rollers, separation, thus corn stem is produced and pulls down
The power taken.
In said structure, the stress of blade concentrates at fastening bolt, easily causes blade deformation in work process.
Now many intensity being increased blade by increased blade thickness, but increased limited by the limited thickness of structure.This
Outward, make relatively costly because of the reason of blade material and processing technique.
Utility model content
Technical problem to be solved in the utility model is: providing a kind of stem pulling roller, this stem pulling roller not only can carry
High stem pulling effect, and make the blade uniform force on stem pulling roller, extend the service life of blade.
For solving above-mentioned technical problem, what this utility model used technical scheme is: a kind of stem pulling roller, bag
Including blade, described blade is fixed on intermediate tubular shaft by threaded fastener, also includes the pressure with kink
Plate, described pressing plate is set on described threaded fastener, and clamps in described blade and described threaded fastener
Fixing head between.
Improving as one, each blade is all fixed on described intermediate tubular shaft by independent threaded fastener
On.
Employing technique effect acquired by technique scheme is:
Owing to described pressing plate is set on described threaded fastener, and clamp in described blade tight with described screw thread
Between the fixing head of firmware, threaded fastener compresses blade by bending pressing plate, disperses the tight of threaded fastener
Gu power makes blade stress more equalize, extend the service life of blade.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of this utility model blade stem pulling state；
Fig. 2 is the structural representation of this utility model bending pressing plate stem pulling state；
In figure, 1-intermediate tubular shaft, 2-blade, 3-bending pressing plate.
Detailed description of the invention
As it is shown in figure 1, a kind of stem pulling roller, including intermediate tubular shaft 1, blade 2 and bending pressing plate 3, blade
The sheet number of 1 can adjust according to reality, and bending pressing plate 3 and blade 2 are fixed on intermediate tubular shaft by threaded fastener
On 1, blade 2 clamps between bending pressing plate 3 and intermediate tubular shaft 1.
Assembling is used by stem pulling roller group of the present utility model, and a pair stem pulling rolls out row and correspondence is installed on Semen Maydis and receives
Obtain on machine, during installation, ensure blade 1 correspondence respectively of two stem pulling rollers.During two stem pulling rollers rotate against,
Cane is produced the power pulled downwards.
Jointly shown in conjunction with Fig. 1 and Fig. 2, two blades can play the effect of stem pulling.Rotate against in stem pulling
During, bending pressing plate 3 also can play the effect of stem pulling, say, that is both rotation one circle and compares existing
Structure pulls number of times kind times to corn stem, thus improves the Grasping skill to corn stem.Bending pressure
Plate 3 can also make the clamping force suffered by blade 2 uniform.Self-strength is also played by the bending of bending pressing plate 3
Potentiation, makes the service life of stem pulling roller and transaction capabilities all be improved simultaneously.
