Abstract
The utility model discloses a thresher roller capable of reducing breakage of rice grain. The thresher roller includes flexile threshing teeth, a support plate, a press plate, a shaft, a web, an end cover plate, and a connection component. The shaft, the web and the end cover plate form a cylindrical threshing roller, the flexile threshing teeth pass through the support plate and the web and are pressed on the support plate by the press plate, the connection component connects the flexile threshing teeth, the web, the support plate and the press plate together. The flexile threshing teeth are fixedly and helically mounted on the web of the threshing roller which evolves along circumference. The threshing roller made of flexile material threshes paddy by soft impact and combing, which can prevent breakage of internal structure of grain, improve quality of rice before processing, and reduce breakage ratio.
Description
Technical field
The utility model relates to a kind of paddy thresher, particularly a kind of thresher drum that reduces the rice grain breakage.
Background technology
The rice threshing operation is an onerous toil.And needed to be grasped the time of threshing, threshing be after can reducing harvest yield and grain quality late, even influences follow-up work.Methods of threshing commonly used is divided into half and feeds, feeds entirely and threshing prior to cutting.The threshing tooth of existing paddy thresher all is a rigid teeth; adopt the rigidity threshing to rob harvesting rice and brought into play due positive role farming season holding; but the rigidity methods of threshing has increased the rift valley rate of paddy, has reduced the head rice yield of rice, has correspondingly reduced the Rice Production benefit.If be used for gathering in the crops rice paddy seed, rigidity threshing even influence the germination rate of rice paddy seed.
Simultaneously rainy season at a time when the south early rice results, air humidity is big, climatic variation impermanence, paddy rice moisture height.And high humidity paddy rice fragility increases, and moist weak, intensity weakens, and rigid teeth is impacted increases percentage of damage easily, even increases the stress of seed inside, is unfavorable for the improvement of rice processing quality.For solving the problem of high humidity rice threshing difficulty, need to increase the strike effect of threshing system, and traditional rigid teeth increases rigid shock and will increase local stress in the seed, and damage seed interior reduces the milled rice rate of rice seed germination rate and rice processing and becomes a meter rate.As adopt soft impact and curry, not only grain can be taken off, nor cause in straw, cane etc. is impacted., can not damage the grain interior yet, can improve the preceding quality of paddy processing, not damage the activity of seed because its active force is suitable.
The utility model content
The purpose of this utility model provides a kind of simple in structure, thresher drum that can reduce the rice grain breakage.
For achieving the above object, technical solutions of the utility model are: constitute the cylindrical shape threshing cylinder by polylith former, two end casings, axles, be fixed with some flexible threshing teeth on the described former.
In the thresher drum of above-mentioned reduced rice grain breakage, described flexible threshing tooth installs by the spiral rule on the threshing cylinder former that launches along circumference.
In the thresher drum of above-mentioned reduced rice grain breakage, former and gripper shoe are passed by described flexible threshing tooth root portion, are pressed on the gripper shoe by pressing plate.
Operation principle of the present utility model: during work; flexible tooth is under the drive of rotating shaft and directs at shape; similar rigid teeth curries the paddy rice fringe and impacts, but because flexible tooth itself is flexible, so the rotational kinetic energy of cylinder all can not passed to the paddy rice fringe; but after running into spike of rice; tooth buckles, and increases flexible tooth and spike of rice time of contact, thereby it is less to give the impulsive force of rice grain; as long as drum speed is suitable just to be shot down seed, finish threshing course.
The beneficial effects of the utility model: the utility model adopts flexible material to replace rigid teeth and makes the soft threshing cylinder of a kind of active force, utilize soft impact during threshing and curry, not only grain can be taken off, nor cause in straw, cane etc. is impacted, simultaneously also because its active force is suitable, can not damage the grain interior, can improve the preceding quality of paddy processing, significantly reduce percentage of damage.

Embodiment
Referring to Fig. 1 and Fig. 2, the utility model is made up of flexible threshing tooth 1, gripper shoe 2, pressing plate 3, axle 4, former 5, end casing 6 and coupling assembling 7.Axle 4, former 5, end casing 6 constitute nonocclusive cylindrical shape threshing cylinder, end casing 6 is arranged to spoke-like, axle 4 outer sleeve-bearings are packed in whole cylinder on the frame (not showing), flexible threshing tooth 1 is by former 5 and gripper shoe 2, be pressed on the gripper shoe 2 with pressing plate 3, coupling assembling 7 is close to flexible threshing tooth 1, former 5, gripper shoe 2 is in the same place with pressing plate.The flexible material that flexible threshing tooth 1 can be similar to nylon rod is made, and flexible threshing tooth 1 is packed on the former 5 by the spiral rule on the threshing cylinder that launches along circumference.
Threshing cylinder of the present utility model can be arranged to as required with the form of former 5 along the circumference sealing.In addition, end casing 6 also is arranged to disc type as required.
Claims (5)
1, a kind of thresher drum that reduces the rice grain breakage constitutes the cylindrical shape threshing cylinder by polylith former, two end casings, axles, it is characterized in that: be fixed with some flexible threshing teeth on the described former.
2, the thresher drum that reduces the rice grain breakage according to claim 1 is characterized in that: described flexible threshing tooth installs by the spiral rule on the threshing cylinder former that launches along circumference.
