Abstract

The utility model relates to a harvester adopting a drum-type separating and cleaning device. The harvester comprises a reel, a cutting apparatus, a header auger, a conveying chain harrow, a threshing drum, a centrifugal fan, a blower, a rethreshing passage, a drum screen, a concave screen, a horizontal grain conveying auger, a grain collecting hopper, a threshing barrel and a perpendicular grain lifting auger; the threshing drum, the threshing barrel and the drum screen are arranged lengthways; an appropriate space is reserved between the concave screen and the horizontal grain conveying auger in the threshing barrel to serve as an air duct; an upper end outlet of the perpendicular grain lifting auger is connected with a small end inlet of the drum screen; the drum screen and the threshing drum are arranged in parallel and are placed in the grain collecting hopper; the rethreshing passage is arranged at the front end of the grain collecting hopper and is communicated with a threshing barrel cover; and a large end outlet of the drum screen is communicated with a suction inlet of the centrifugal fan. The harvester provided by the utility model has the characteristics of simple structure, small size and low gravity center, and has the advantages that the crop lifting height and the conveying processes are reduced, and the power consumption is decreased.

Description

Adopt the grain header of drum-type separating cleaning device

Technical field

The utility model belongs to agricultural machinery technological field, relates to a kind of grain header that is applicable to the employing drum-type separating cleaning device of lower position threshing.

Background technology

The structure that the separating cleaning device of existing combine all adopts straw shaker, vibratory sieve to add selection by winnowing is carried out separating cleaning; Because straw shaker, vibratory sieve air channel are located at the below of threshing cylinder concave grate; Occupied bigger space, bottom and made the position of threshing cylinder carry very highly, thereby made that machine volume is huge, the low crop hoisting depth of center of gravity is high, long flow path and power consumption are big.

The utility model content

In order to overcome the above-mentioned shortcoming of prior art ,The utility model provide a kind of simple in structure, volume is intensive, the grain header of in light weight, center of gravity is low, power consumption is few employing drum-type separating cleaning device.

The utility model solves the technical scheme that its technical problem adopted: a kind of grain header that adopts drum-type separating cleaning device; Comprise straw shift wheel, cutter, ceding of Taiwan auger, carry chain harrow, threshing cylinder, centrifugal blower, blower fan, take off passage, rotary screen, concave grate, the defeated paddy auger of level, rice-collecting bucket, threshing barrel and the vertical paddy auger of carrying again; Breaking away from cylinder, threshing barrel and rotary screen vertically places; Leave between concave grate and the defeated paddy auger of level in the threshing barrel between proper air as the air channel, vertically carry paddy auger upper end and export and link to each other with the little end entrance of rotary screen; The parallel placement of rotary screen with threshing cylinder, and place in the rice-collecting bucket, the rice-collecting bucket front end is provided with and takes off passage again, is connected with the threshing bung, and rotary screen brings out mouth greatly and is connected with the centrifugal blower suction inlet.

Rotary screen adopts whole conical structure, and the punching sieve plate is adopted on the sieve nest surface, and interior welds has guide plate, and the big end of sieve nest is provided with assorted surplus, short original text floss hole.

The beneficial effect of the utility model is: have simple in structure, little, the underslung characteristics of machine volume, and reduced the crop hoisting depth and carried flow process, reduced power consumption.

Description of drawings

Fig. 1 is the utility model structural representation.

Among the figure: the 1-straw shift wheel, the 2-cutter, 3-ceding of Taiwan auger, 4-carries chain harrow, 5-threshing cylinder; 6-centrifugal blower, 7-take off passage again, the 8-rotary screen, and 9-rice-collecting bucket, 10-are vertically carried the paddy auger; The 11-threshing barrel, the 12-concave grate, the 13-level is failed the paddy auger,, the 14-blower fan.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Referring to Fig. 1; A kind of grain header that adopts drum-type separating cleaning device; Comprise straw shift wheel 1, cutter 2, ceding of Taiwan auger 3, carry chain harrow 4, threshing cylinder 5, centrifugal blower 6, blower fan 14, take off passage 7, rotary screen 8, concave grate 12, the defeated paddy auger 13 of level, rice-collecting bucket 9, threshing barrel 11 and the vertical paddy auger 10 of carrying again; Breaking away from cylinder 5, threshing barrel 11 and rotary screen 8 vertically places; Leave between concave grates 12 and the defeated paddy auger 13 of level in the threshing barrel 11 between proper air as the air channel, vertically carry paddy auger 10 upper ends and export and link to each other with rotary screen 8 little end entrances; Rotary screen 8 and threshing cylinder 5 parallel placements, and place in the rice-collecting bucket 9, rice-collecting bucket 9 front ends are provided with and take off passage 7 again, are connected with threshing barrel 11 lids, and rotary screen 8 brings out mouth greatly and is connected with centrifugal blower 6 suction inlets.

Rotary screen 8 adopts whole conical structure, and the punching sieve plate is adopted on the sieve nest surface, and interior welds has guide plate, and the big end of sieve nest is provided with assorted surplus, short original text floss hole.

Its operation principle is: crop is under the effect of straw shift wheel 1; Guide crop that cutter 2 cuts off into through ceding of Taiwan auger 3; Carry chain harrow 4 to deliver into threshing cylinder 5 threshings; The assorted surplus short original text of seed in the emersion object, clever shell and part falls into threshing barrel 11 bottoms after the separation of concave grate 12, fall in the process, blows out at blower fan 14 that most clever shell is blown outside the machine under the effect of air-flow; Long shoot is axially discharged through straw outlet along threshing cylinder 5; The mixture of deviating from that falls into threshing barrel 11 bottoms is promoted to rotary screen 8 inlets through the defeated paddy auger 13 of level with the vertical paddy auger 10 of carrying; Axially get into rotary screen 8 and carry out separating cleaning; The grain of cleaning falls along the cylinder surface sieve aperture and gets into rice-collecting bucket 9, and short original text and do not purify assorted surplusly move axially to the outlet of rotary screen 8 along rotary screen 8 is under the effect of centrifugal force and moving tooth; Radially throw away through taking off passage 7 again and get into threshing cylinder 5 threshings once more, a little clever shell is under the attraction of centrifugal blower 6 outside the discharge machine.

The utlity model has simple in structure, little, the underslung characteristics of machine volume, and reduced the crop hoisting depth and carried flow process, reduced power consumption.
