Abstract
The invention relates to a threshing and cleaning device for a longitudinal axial flow combined harvester. The threshing and cleaning device comprises a threshing cylinder, a concave plate sieve, a planar vibrating sieve and a fan. An oblique grain conveying transition device with a low front and a high rear is mounted between the concave plate sieve and the planar vibrating sieve and is positioned at the rear of the concave plate sieve and the rear of the planar vibrating sieve. The threshing and cleaning device has the advantages that the grain conveying transition device with the low front and the high rear is mounted between the concave plate sieve and the planar vibrating sieve, so that materials on the rear half section of the concave plate sieve drop onto the grain conveying transition device at first and then fall to the front half portion of the planar vibrating sieve from the transition device, and loss due to the fact that grains which fall from the rear of an existing concave plate sieve are blown or vibrated to the outside of an existing device can be effectively and completely eradicated; parts of grains on the grain conveying transition device can be cleaned again, accordingly, load on the planar vibrating sieve can be relieved, the cleaning efficiency can be improved, and a cleaning rate can be increased.
Description
Technical field
The invention belongs to grain header equipment technical field, relate to a kind of threshing cleaning unit for longitudinal axial flow combine.
Background technology
The threshing cleaning unit of existing longitudinal axial flow combine, half arc concave grate outside threshing cylinder of the threshing cylinder that the level that generally includes is installed, ladle cover, is positioned at plane vibration sieve and blower fan below concave grate.In watering and separation procedure, due to vibration and the blower fan blowing backward of sorting screen, often make part material that concave grate rear portion falls can not fall above plane vibratory sieve but directly fall into field, cause damage.
Summary of the invention
In order to overcome the above-mentioned shortcoming of prior art
,the invention provides and a kind ofly have that cleaning efficiency is high, the threshing cleaning unit for longitudinal axial flow combine of the low feature of cleaning loss percentage
.
The technical solution adopted for the present invention to solve the technical problems is: a kind of threshing cleaning unit for longitudinal axial flow combine
,comprise threshing cylinder, concave grate, plane vibration sieve and blower fan, a transition apparatus that is positioned at the low early and high after skewed cereal conveying of being of both rear portions is installed between concave grate and plane vibration sieve.
Described transition apparatus forms by cereal sliding panel with for the driving mechanism that drives cereal sliding panel to make front-rear reciprocation movement, up-down vibration.
In the both sides of described cereal sliding panel, be provided with vertical rib, the width of described vertical rib is greater than the sliding plate of concave grate middle.
Described sliding plate is to recessed and present bell mouth shape wide at the top and narrow at the bottom.
Described driving mechanism comprise the front axle that is positioned at cereal sliding panel front end that is fixed between two vertical ribs, by bearing block be installed on bottom after cereal sliding panel the rear axle parallel with front axle, be installed on the driving-chain wheelchair on rear axle one end and the vibratory sieve power transmission shaft that is connected by chain power with driving-chain wheelchair on sprocket wheel and the connection sprocket wheel being connected with sprocket wheel.
On described driving-chain wheelchair, eccentric adjusting piece is installed.
Angle α between described cereal sliding panel and plane vibration sieve is 10-40 degree.
It is low early and high after skewed that described threshing cylinder and concave grate are, and the central axis of threshing cylinder and concave grate is parallel with cereal sliding panel.
The invention has the beneficial effects as follows: low early and high after skewed due to the concave grate of former horizontal setting is changed into, and between concave grate and plane vibration sieve, the transition apparatus that low early and high after cereal is carried is installed, thereby the second half section material on concave grate is first fallen on the transition apparatus of cereal conveying, from transition apparatus, drop to again the first half of plane vibration sieve, so just can effectively stop the cereal that concave grate rear portion falls and blown or shaken the loss causing to device outside, and part cereal has obtained again cleaning on the transition apparatus of cereal conveying, thereby reduced the load of plane vibration sieve, cleaning efficiency and clean rate have been improved.

Embodiment
Below in conjunction with drawings and Examples, the present invention is further described.
Referring to Fig. 1～Fig. 3, a kind of threshing cleaning unit for longitudinal axial flow combine
,comprise threshing cylinder 1, concave grate 2, plane vibration sieve 4 and blower fan 5, a transition apparatus 3 that is positioned at the low early and high after skewed cereal conveying of being of both rear portions is installed between concave grate 2 and plane vibration sieve 4, transition apparatus 3 is by cereal sliding panel 7 with for driving cereal sliding panel 7 to make front-rear reciprocation movement, the driving mechanism of up-down vibration forms, in the both sides of cereal sliding panel 7, be provided with vertical rib, the width of vertical rib is greater than concave grate 2 middles to recessed and present the sliding plate of bell mouth shape wide at the top and narrow at the bottom, driving mechanism comprises the front axle 6 that is positioned at cereal sliding panel 7 front ends being fixed between two vertical ribs, by bearing block 9, be installed on the rear bottom of cereal sliding panel 7 rear axle 8 parallel with front axle 6, sprocket wheel 15 on vibratory sieve 4 power transmission shafts 14 that are installed on the driving-chain wheelchair 10 on rear axle 8 one end and are connected by chain 13 power with driving-chain wheelchair 10 and the connection sprocket wheel 12 being connected with sprocket wheel 15, eccentric adjusting piece 11 is installed on driving-chain wheelchair 10, angle α between cereal sliding panel 7 and plane vibration sieve 4 is 10-40 degree, it is low early and high after skewed that threshing cylinder 1 and concave grate 2 are, the central axis of threshing cylinder 1 and concave grate 2 is parallel with cereal sliding panel 7.
In real work, harvesting is except the standing grain fringe under machine cut is after threshing cylinder 1 threshing, straw is discharged from the rear portion of threshing cylinder 1, grain and tiny foreign material are fallen concave grate 2 from the bottom of thrashing cylinder, after concave grate 2 screenings, the blower fan 5 that most of foreign material are installed in device front end on concave grate 2 goes out concave grate 2 to the wind of after-blow and falls field, and concave grate 2 first halfs are entrained with the first half that assorted remaining cereal drops to vibratory sieve 4, the cereal of the latter half of concave grate 2 can drop on the transition apparatus 3 of cereal conveying effect, by reciprocating motion and the vibration of transition apparatus 3, make cereal kernel fall uniformly the postmedian of plane vibration sieve 4, vibratory sieve 4 is also by moving back and forth, make cereal kernel with assorted remaining separated, same under the blowing effect of blower fan 5, more than assorted, blow to field, cereal kernel is fallen on 4 times masters' of plane vibration sieve conveying screw feeder, by screw feeder, be transported on grain header silo or put in grain sack.
