Abstract
The utility model relates to a threshing and separating unit of a combine harvester, comprising a body case, a driving unit, a threshing unit and a grain cleaning unit. The threshing unit consists mainly of a main threshing mechanism and an auxiliary threshing device. The grain cleaning unit contains a blower and an overall inclined vibration screen on the upper section of the blower. The bottom of the vibration screen that corresponds with the main threshing mechanism is provided with a screw conveyor. The bottom of the end of the vibration screen is provided with a secondary screw conveyer. The secondary screw conveyer is connected with the feeding port of the auxiliary threshing mechanism. The utility model improves the threshing percentage of grains and reduces the impurity rate and loss rate.
Description
(1) technical field
The utility model relates to a kind of installed threshing separator of combine.
(2) background technology
The grain threshing mechanism of existing combine has following 3 kinds: 1, single axial stream separating mechanism; 2, twin shaft stream separating mechanism; 3, the Rethresher structure that has underneath type.Chinese patent 00207182 discloses a kind of installed threshing separator of combine, include and be installed on the frame by power-actuated threshing cylinder, be in the concave grate of threshing cylinder bottom, be positioned at the drum cover on threshing cylinder top, wherein installed threshing separator is to be made of two threshing separation chambers, and the outlet of the first threshing separation chamber just is the inlet of the second threshing separation chamber.Though can be more effective when this device is used for threshing than general single axial stream separating mechanism, when being used for bigger seed of bonding strength and cob threshing, also often exist the unclean shortcoming of threshing.
(3) utility model content
The technical problems to be solved in the utility model is to provide a kind of installed threshing separator of combine of simple in structure, through threshing.
The installed threshing separator of described combine; comprise frame, transmission device, sheller unit, cleaning mechanism; described sheller unit comprises main separating mechanism, auxiliary thresher structure; described cleaning mechanism comprises that blower fan and blower fan top totally are skewed vibratory sieve; described vibratory sieve is provided with conveying worm corresponding to the below of main separating mechanism; described vibratory sieve end below is provided with second conveying worm, the charging aperture of the described second conveying worm auxiliary connection separating mechanism.
Further, described main separating mechanism is made up of threshing cylinder, the concave grate that is positioned at the drum cover of threshing cylinder top and is positioned at the threshing cylinder below.
Further, described auxiliary thresher structure is made up of threshing cylinder, the concave grate that is positioned at the drum cover of threshing cylinder top and is positioned at the threshing cylinder below.
The structure of above-mentioned threshing cylinder is conventionally known to one of skill in the art.
Outstanding effect of the present utility model is: during combine work; the vibratory sieve that does not purify; on spike of rice (wheat head) or the paddy that has a straw under the double action of vibratory sieve and blower fan; enter second conveying worm; be sent to auxiliary cylinder,, paddy (wheat) thoroughly separated with straw again through the strike of auxiliary thresher structure with rub; thereby improved the threshing performance of cereal, reduced percentage of impurity and percent of loss.The spike of rice (wheat head) that process auxiliary thresher structure purifies not yet enters the auxiliary thresher structure repeatedly and carries out threshing under fan action, thereby has improved the threshing performance of crop.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
(5) embodiment
The utility model is described in further detail below in conjunction with embodiment, but protection domain of the present utility model is not limited to this.
With reference to Fig. 1; a kind of installed threshing separator of combine; comprise frame, transmission device, sheller unit, cleaning mechanism; sheller unit comprises main separating mechanism 1, auxiliary thresher structure 2, and main separating mechanism is made up of threshing cylinder 3, the concave grate 5 that is positioned at the drum cover 4 of threshing cylinder 3 tops and is positioned at threshing cylinder 3 belows.Auxiliary thresher structure 2 is made up of threshing cylinder 6, the concave grate 8 that is positioned at the drum cover 7 of threshing cylinder 6 tops and is positioned at threshing cylinder 6 belows.Cleaning mechanism comprises that blower fan 9 and blower fan 9 tops totally are skewed vibratory sieve 10; vibratory sieve 10 is provided with conveying worm 11 corresponding to the below of main separating mechanism 1; vibratory sieve 10 terminal belows are provided with the charging aperture 13 of second conveying worm, 12, the second conveying worms, 12 auxiliary connection separating mechanisms 2.
During combine work; the careless advanced person of rice (wheat) becomes owner of separating mechanism 1; after the strike of ratch on the threshing cylinder 3 and concave grate 5 is rubbed; most rice (wheat) grass is derived outside the frame with the careless muscle of leading on the drum cover 4, and fraction paddy (wheat), spike of rice (wheat head) and tiny straw drop on vibratory sieve 10.Under the double action of vibratory sieve 10 and blower fan 9; heavy paddy (wheat) directly enters conveying worm 11 collections and puts in storage; the straw that proportion is little is blown outside the frame; then can enter second conveying worm 12 between the spike of rice between the two (wheat head); and then be sent to auxiliary thresher structure 2; again in threshing cylinder 6 strike of ratch and concave grate 8 and rub after, evenly scatter back on the vibratory sieve 10 by discharging opening 14, go round and begin again.
Claims (3)
1, a kind of installed threshing separator of combine; comprise frame, transmission device, sheller unit, cleaning mechanism; described sheller unit comprises main separating mechanism, auxiliary thresher structure; described cleaning mechanism comprises that blower fan and blower fan top totally are skewed vibratory sieve; described vibratory sieve is provided with conveying worm corresponding to the below of main separating mechanism, it is characterized in that:
Described vibratory sieve end below is provided with second conveying worm, the charging aperture of the described second conveying worm auxiliary connection separating mechanism.
2, the installed threshing separator of combine as claimed in claim 1 is characterized in that:
Described main separating mechanism is made up of threshing cylinder, the concave grate that is positioned at the drum cover of threshing cylinder top and is positioned at the threshing cylinder below.
