Abstract
The utility model discloses a grain threshing roller device. The grain threshing roller device comprises a main roller, the periphery of the right side of the main roller is further provided with spike teeth which are distributed at intervals in the circumferential direction and arranged in two rows or more, and all rows of spike teeth and separation plates are alternately arranged in the circumferential direction of the main roller. When the grain threshing roller device is in use, gaps between ears and stalks are separated through every two adjacent separation plates, and the spike teeth can stir the stalks and the ears again so that the ears which are bonded with the stalks can be separated from the stalks. In this way, in the grain separation process, the separation plates and the spike teeth alternately work, and therefore the ears and the stalks are stirred and separated alternately. Accordingly, the stalks and the ears can be better separated through the separation plates, the threshing effect of grains is improved, work efficiency of threshing is enhanced, and the loss of the ears is reduced.
Description
Technical field
The utility model relates to a kind of grain threshing roller device.
Background technology
At present, in grain harvest process, cereal completes threshing operation by threshing cylinder in reaping machine, and as shown in Figure 1, traditional threshing cylinder comprise master rotor 10 and on the rasp bar 11 and the separating plate 12 that set firmly, rasp bar 11 at the left end of master rotor 10 along circumferentially uniformly at intervals, separating plate 12 has two circles, every circle separating plate 12 all master rotor 10 weeks upwards uniformly at intervals, in use, the threshing of cereal is completed by rasp bar 11, i.e. the rubbing fruit ear threshing from stem stalk cereal by rasp bar 11, after stem stalk being separated by separating plate 12 again, the separated plate 12 of stem stalk is dished out from straw outlet, but in the time that cereal is moist, separating plate 12 often can not separate stem stalk totally with fruit ear, thereby tend to carry secretly some fruit ears in the stem stalk that straw outlet is discharged, and also can carry some stem stalks secretly in the fruit ear that rice outlet is discharged, so that the threshing precision of cereal reduces, later stage separating difficulty increases, extend the cycle of grain threshing, reduce the efficiency of threshing operations.
Utility model content
The purpose of this utility model is to provide a kind of grain threshing roller device that improves grain threshing effect.
In order to realize above object, in the utility model, the technical scheme of cereal threshing cylinder is as follows:
A kind of grain threshing roller device, comprise the master rotor that extend left and right, in the periphery of master rotor left side, be laid with along being laid with in circumferentially rasp bar uniformly at intervals, right side periphery along circumferential separating plate uniformly at intervals, in the right side periphery of described master rotor, be also laid with the spike-tooth that left and right is intervally arranged, each nail tooth and separating plate are alternately arranged on master rotor is circumferential.
Described separating plate has two circles above and arranges at left and right directions, and in two adjacent rings separating plate, each separating plate is in left and right directions interlaced arrangement.
Described separating plate has two circles, the circle separating plate corresponding position that described spike-tooth is kept right in master rotor periphery.
Described each nail tooth is the centre position place between adjacent two separating plates respectively.
The utility model is also laid with along the spike-tooth being circumferentially intervally arranged in the periphery of the right side of master rotor, and more than described spike-tooth has two rows, each nail tooth and separating plate are alternately arranged on master rotor is circumferential.In use, separate the gap of fruit ear and stem stalk at adjacent two separating plates, spike-tooth can stir again to stem stalk and fruit ear, so that the fruit ear being sticked together is separated with stem stalk, thereby makes in cereal separation process, separating plate and spike-tooth alternately operating, and make that fruit ear replaced with stem stalk stirring and separating, therefore separating plate can be better by stem stalk and fruit ear separately, improved the Threshing of cereal, and improved the operating efficiency of threshing operations, reduce the loss of fruit ear.
Accompanying drawing explanation
Fig. 1 is the structural representation of grain threshing device in prior art;
Fig. 2 is the structural representation of a kind of embodiment of the utility model.
Embodiment
The embodiment of cereal threshing cylinder in the utility model: as shown in Figure 2, this grain threshing roller device comprises the master rotor 20 being connected on main shaft, in master rotor 20 left side peripheries, be laid with along being laid with in circumferentially rasp bar 21 uniformly at intervals, right side periphery along circumferential separating plate 22 uniformly at intervals, separating plate 22 has two circles and arranges at left and right directions, and in two circle separating plates 22, each separating plate 22 is in left and right directions interlaced arrangement.In the right side periphery of master rotor 20, be also laid with the spike-tooth 23 that left and right is intervally arranged, each nail tooth 23 is alternately arranged on master rotor 20 is circumferential with a circle separating plate 22 of keeping right, and each nail tooth 23 centre position place between adjacent two separating plates 22 respectively.
The present embodiment, on the basis of original separating plate 22, has increased spike-tooth 23, adopts and adds a nail tooth 23 every row's separating plate 22, like this in crop High Rotation Speed, can millet straw better be separated by spike-tooth 23, even if in the time that crop is moist, also can guarantee better separating effect.
In the above-described embodiments, each nail tooth is the centre position place between adjacent two separating plates respectively, and in other embodiments, each nail tooth departs from position in the middle respectively between adjacent two separating plates.
In the above-described embodiments, separating plate has two circles, and in other embodiments, separating plate can be also more than a circle or two encloses.
In the above-described embodiments, the circle separating plate corresponding position that spike-tooth is kept right in master rotor periphery, in other embodiments, all offers spike-tooth is set in each circle separating plate corresponding position.
Claims (4)
1. a grain threshing roller device, comprise the master rotor that extend left and right, in the periphery of master rotor left side, be laid with along being laid with in circumferentially rasp bar uniformly at intervals, right side periphery along circumferential separating plate uniformly at intervals, it is characterized in that, in the right side periphery of described master rotor, be also laid with the spike-tooth that left and right is intervally arranged, each nail tooth and separating plate are alternately arranged on master rotor is circumferential.
2. grain threshing roller device according to claim 1, is characterized in that, described separating plate has two circles above and arranges at left and right directions, and in two adjacent rings separating plate, each separating plate is in left and right directions interlaced arrangement.
