Technical field
The utility model relates to a kind of combine annex, relates in particular to a kind of combine harvester assembly.
Background technology
Combine is the operation such as the harvesting that can disposablely complete cereal, threshing, removing foreign material and then directly from field, obtains the harvest machinery of grain, can reduce the threshing loss, reduce labour intensity, save the labour with respect to the hand harvest, be the indispensable farm machinery of land for growing field crops operation; Existing baby combine generally adopts the threshing cylinder with teeth structure, Miao Sui pulverizes more serious, produce a large amount of seedling bar chips, extremely difficult removing, usually needing that fan blower is installed is cleaned, and the pneumatic separator structure not only consumes a large amount of driving energy of grain header, also can make seedling bar chip wave in surrounding environment under the wind-force effect, operating environment is severe.
Therefore, for addressing the above problem, need to be improved existing combine threshing assembly, be reduced the fragmentation to the seedling fringe, be reduced the generation of seedling bar chip, be beneficial to the operating environment of cleaning and keeping friends with of seed.
The utility model content
In view of this, the purpose of this utility model is to provide a kind of combine harvester assembly, be provided with threshing cylinder and removal of impurities cylinder, while adopting the threshing cylinder of rasp bar formula, destruction to the seedling fringe is little, can keep the integrality of seedling bar in threshing course, reduce the generation of seedling bar chip, be beneficial to the operating environment of cleaning and keeping friends with of seed.
Combine harvester assembly of the present utility model, comprise threshing cylinder, removal of impurities cylinder and cylinder case for being arranged on the frame on the grain header walking assembly and being installed on described frame; Described threshing cylinder and removal of impurities cylinder all are located in the inner chamber of cylinder case and the removal of impurities cylinder is positioned at the top of threshing cylinder;
Further, described threshing cylinder is rasp bar formula structure, and described removal of impurities cylinder is the spiketooth type structure.
Further, described cylinder case comprises end cover, upper cover and screen cloth; Along the removal of impurities drum shaft, to an end, uncovered and upper cover inwall is fixed with the spiral catch to described upper cover; Described spiral catch and removal of impurities cylinder coaxially arrange;
Further, the front of described screen cloth along and all be fixed in end cover inwall along the edge of grain header both lateral sides; The front portion of screen cloth is for the coaxial cambered surface filter of removal of impurities cylinder and by this cambered surface filter, the inner chamber of cylinder case is divided into to removal of impurities chamber and threshing cavity, and the rear portion of screen cloth turns down downwards and forms the guiding filter and import the removal of impurities chamber for the seedling fringe by after threshing cylinder processing;
Further, the spike-tooth dislocation be positioned on described removal of impurities cylinder on adjacent two circumference is arranged;
Further, the corresponding threshing cylinder in cover front side, the described end axially offers the charging aperture that enters threshing cavity for the seedling fringe.
The beneficial effects of the utility model are: combine harvester assembly of the present utility model, be provided with threshing cylinder and removal of impurities cylinder, while adopting the threshing cylinder of rasp bar formula, destruction to the seedling fringe is little, can keep the integrality of seedling bar in threshing course, reduce the generation of seedling bar chip, be beneficial to the operating environment of cleaning and keeping friends with of seed.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is structural representation of the present utility model.
Embodiment
Fig. 1 is structural representation of the present utility model, as shown in the figure: the combine harvester assembly of the present embodiment comprises threshing cylinder 2, removal of impurities cylinder 3 and cylinder case for being arranged on the frame 1 on the grain header walking assembly and being installed on described frame 1; Described threshing cylinder 2 and removal of impurities cylinder 3 all are located in the inner chamber of cylinder case and removal of impurities cylinder 3 is positioned at the top of threshing cylinder 2.
In the present embodiment, described threshing cylinder 2 is rasp bar formula structure, described removal of impurities cylinder 3 is the spiketooth type structure, first by 2 pairs of seedling fringes of threshing cylinder with rib, carry out threshing, after threshing or the seedling fringe of half threshing deliver to removal of impurities cylinder 3 places under the centrifugal action of threshing cylinder with rib 2, the effect of knocking by 3 pairs of seedling fringes of removal of impurities cylinder can be carried out the secondary threshing, guarantee that seed purifies, certainly rationally control the rotating speed of removal of impurities cylinder 3 to avoid the pulverizing of seedling fringe, the axial flow under the drive of removal of impurities cylinder 3 of the seedling fringe after threshing is discharged; The destruction of 2 pairs of seedling fringes of threshing cylinder of rasp bar formula is little, can keep the integrality of seedling bar in threshing course, reduces the generation of seedling bar chip, is beneficial to the operating environment of cleaning and keeping friends with of seed.
In the present embodiment, described cylinder case comprises end cover 4, upper cover 5 and screen cloth 6; The inner chamber of cylinder case is fastened on end cover 4 and is formed by upper cover 5; Along the axial end of removal of impurities cylinder 3, uncovered and upper cover 5 inwalls are fixed with spiral catch 7 to described upper cover 5; Described spiral catch 7 coaxially arranges with removal of impurities cylinder 3, the seedling fringe after threshing can be discharged to reasonable in design along removal of impurities cylinder 3 axial leads and by the opening end of upper cover 5 by the guide effect of spiral catch 7.
In the present embodiment, the front of described screen cloth 6 along and all be fixed in the end along the edge of grain header both lateral sides and cover 4 inwalls; The front portion of screen cloth 6 is the cambered surface filter coaxial with removal of impurities cylinder 3 and by this cambered surface filter, the inner chamber of cylinder case is divided into to removal of impurities chamber 8 and threshing cavity 9, the rear portion of screen cloth 6 turns down downwards and forms the guiding filter for the seedling fringe after threshing cylinder 2 processing is imported to removal of impurities chamber 8, by screen cloth 6, the corresponding threshing cylinder 2 of cylinder case inner chamber and removal of impurities cylinder 3 are effectively isolated, the seedling fringe of seed after the eyelet of screen cloth 6 falls into threshing cavity 9 to make threshing simultaneously come off under the effect of removal of impurities cylinder 3 discharged along the opening end of upper cover 5.
