Description
Technical field
The present invention relates to agricultural tool processing technique field, a kind of is the rice threshing gathered in the device separated from stem stalk and impurity by grain.
Background technology
Oryza sativa L. originates in the south of China more, and south mostly is mountain area, the rice harvesting in mountain area can not use large-scale harvesting apparatus, use hand harvest's threshing efficiency low, and labor intensity is very big, in order to solve this problem, south abounds with the people in Oryza sativa L. area and constantly improves the tool of production, producing the equipment of applicable southern area rice harvesting and threshing, the threshing machine of the present inventor is the equipment taken off from stem stalk by the rice grain gathered in and separate from stem stalk and impurity.
Summary of the invention
Problem to be solved by this invention is to provide a kind of threshing machine, and the grain on Oryza sativa L. that can will have gathered in the most up hill and dale is taken off and separated from stem stalk and impurity.
In order to solve the problems referred to above, the technical scheme is that this threshing machine includes that frame, described frame both sides and rear side are respectively equipped with side plate and back plate, described frame top is provided with cover body, and described cover body is uncovered in described frame front；Described frame is provided with knife rest in described back plate top, and described knife rest is evenly arranged with polylith cutting edge cutting knife forward side by side；Being provided with grain threshing roller on the side plate of described both sides, described grain threshing roller is uniformly provided with multiple tooth for brushing off grain, described grain threshing roller connects dynamic machine by actuating unit；Two-layer screen cloth is installed under described grain threshing roller, side between described two-layer screen cloth is provided with blower fan, the opening of described blower fan is towards screen cloth described in last layer, the collecting board being arranged right below for receiving grain of next layer of described screen cloth, described collecting board side is provided with discharge bucket, described screen cloth and described collecting board side and is mounted on vibrating device；Described blower fan and described vibrating device connect dynamic machine by actuating unit.
In technique scheme, more specifically scheme may is that described collecting board is obliquely installed, and described discharge bucket is located at the minimum side of described collecting board.
Further: described grain threshing roller is arranged on the side plate of described both sides by the groove on described side plate and retaining pin module.
Owing to have employed technique scheme, the present invention compared with prior art has the advantages that
1, this threshing machine uses the grain threshing roller in frame, and the multiple teeth for brushing off grain being uniformly arranged on grain threshing roller, de-to be brushed from the stem stalk of Oryza glutinosa by grain；Be provided with knife rest at the rear portion of frame and be evenly arranged with polylith cutting edge cutting knife forward side by side, making stem stalk and big miscellaneous leaf be played below by grain threshing roller, cut off by cutting knife, on the stem stalk of cut-out with residue grain by grain threshing roller threshing again；
2, this threshing machine uses the two-layer screen cloth grain to taking off to carry out three grades of sub-sieves, the stem stalk cut off is guided by the guide plate on knife rest, make on it with residue grain by grain threshing roller threshing again, have the stem stalk preventing cutting off to be downwardly into screen cloth simultaneously, play the effect of first order screening；Last layer screen cloth screens out the segment stem stalk of great Ye and residual, the stem and leaf of the lighter in weight of chopping is first blown afloat by blower fan, and blown out by air channel, grain screening less for granule is fallen by the last layer screen cloth of vibration, impurity that granule is come in stem and leaf clamping relatively greatly and the grain that goes mouldy sending out big that makes moist are stayed on next layer of screen cloth outside with falling equipment at vibration movement to the impurities outlet of screen cloth, play the effect that the second level is screened；Owing to the opening of blower fan is towards last layer screen cloth, also have part wind formed below to the air channel above collecting board to this layer and next layer of screen cloth when wind is to last layer screen cloth, can be by the fullest lighter grain blowout collecting board less than grain, make the only the fullest remaining qualified grain of the grain on collecting board, play the effect of third level screening.This threshing machine is on the basis of higher production efficiency, it is achieved that grain is separated the most up hill and dale.

Detailed description of the invention
Below in conjunction with the accompanying drawings the embodiment of the present invention is described in further detail:
This threshing machine as shown in Figures 1 to 4, it includes that frame 1, frame 1 both sides and rear side are respectively equipped with side plate 2 and back plate 13, frame 1 top is provided with cover body 17, cover body 17 is provided with gauze in side, frame 1 rear portion, can observe threshing situation, it is also possible to prevent impurity from splashing out；Hook, convenient handling are had on cover body 17 top；Cover body 17 is uncovered in frame 1 front, in order to put the ripe Oryza sativa L. gathered in.
Frame 1 is provided with knife rest 11 in back plate 13 top, and knife rest 11 is evenly arranged with polylith cutting edge cutting knife 9 forward side by side.Being provided with grain threshing roller 7 on both sides side plate 2, grain threshing roller 7 is arranged on both sides side plate 2 by the groove on side plate 2 and retaining pin module 12；Be uniformly provided with multiple tooth 8 for brushing off grain on grain threshing roller 7, make stem stalk and big miscellaneous leaf be played below by threshing 7, cut off by cutting knife 9, on the stem stalk of cut-out with residue grain by grain threshing roller 7 threshing again.Grain threshing roller 7 connects dynamic machine 16 by actuating unit 14.
Grain threshing roller is provided with two-layer screen cloth 7 times, side between two-layer screen cloth is provided with blower fan 4, the opening of blower fan 4 is towards screen cloth last layer screen cloth 6, the mixture that device above last layer screen cloth 6 falls includes grain, broken stem and leaf, is mixed in the impurity that band in stem and leaf is come in, also make moist and become the grain gone mouldy greatly, these mixture are under blower fan 4 blows wind action, and the stem and leaf of lighter in weight is blown afloat, and blown out by air channel 8；The collecting board 5 being arranged right below for receiving grain of next layer of screen cloth 4, collecting board 5 is obliquely installed, the minimum side being located at collecting board 5 is provided with discharge bucket 18, screen cloth 6 and collecting board 5 side are provided with vibrating device 3, collecting board 5 side is provided with vibrating device 15, collecting board 5 and two-layer screen cloth is vibrated through vibrating device 15, collecting board 5 fallen from the mesh of next layer of screen cloth 4 by the grain of the small volume that mixture weight on next layer of screen cloth 4 is bigger, the filled grain percentage gone mouldy owing to making moist becomes big, stay on next layer of screen cloth 4, the impurity less than filled grain percentage has dropped when putting into threshing machine, only big than filled grain percentage impurity is mingled with entrance threshing machine by stem and leaf, thus impurity is also stayed on next layer of screen cloth 4, fall the only grain on collecting board 5.Blower fan 4 and vibrating device 15 connect engine 16 by actuating unit 14, and engine 16 here is motor.Owing to the opening of blower fan 4 is towards last layer screen cloth 6, also have when wind is to last layer screen cloth 6 part wind between two-layer screen cloth and next layer of screen cloth 4 formed below to collecting board 5 above, can be by the fullest lighter grain blowout collecting board 5 less than grain, make the only the fullest remaining qualified grain of the grain on collecting board 5, thus separate the most thorough.
