Therefore, the multifunctional thresher is applicable for threshing grain of different classes.

Description

Multi-functional thrasher

The utility model relates to a kind of drum-type grain separator, the adjusting device in particularly a kind of separating mechanism of drum-type grain separator.

In the prior art; drum-type grain separator organic frame; horizontal cylinder is arranged on the frame; first cylinder is a shell; second cylinder is a sieve; the cylinder front end has feeding mouth; there is the straw outlet rear end; have in the cylinder and the cylinder of cylinder on same axis; tooth by helical arrangement is arranged on the roll circumference; under the bottom of frame, the semicircular cylinder sieve vibratory sieve is arranged, there is the row straw centrifugal fan coaxial with cylinder in the straw exit of cylinder, and a cereal removal of impurities air-introduced machine coaxial with cylinder is arranged on the rear portion outside cylinder, the vibrating screen surface.The cylinder of this thresher and the gap length between the cylinder are fixed, and thresher only is suitable for can not being suitable for the threshing of various types of grain to a kind of grain threshing.

The utility model is in order to overcome above-mentioned not enough a kind of drum-type grain separator that can adapt to the various types of grain threshing that proposes.

The utility model is realized with the following method.

Be threshing and the raising threshing efficiency that adapts to various types of grain; multi-functional grain separator organic frame; be fixed with the horizontal circle shaft screen on the frame; be covered with cover cap on the drum sieve; have in the drum sieve and the cylinder of drum sieve on same axis; cylinder has axis; tooth by helical arrangement is arranged on the circumference of cylinder; frame lower; under the drum sieve vibratory sieve is arranged; the front end of drum sieve has charging aperture; there is the row straw centrifugal blower coaxial with rotary screen the rear end of drum sieve; sidewall at drum sieve has the cereal selector vertically; the cereal selector has the tooth plate of appearance with drum sieve etc.; a side of tooth plate has another side of tooth that axle is arranged; on the sidewall of axle in drum sieve of tooth plate; cover on the wall of the cover cap on the drum sieve; there is screw on the tooth plate side; be rotary with screw rod in the screw; one end of screw rod withstands on the tooth plate; the other end of screw rod has crank; shake crank, screw rod can be in the motion of the radial expansion of drum sieve, can promote the tooth plate activity of directly marching forward; thereby regulate the side wall surface of cylinder and the gap between tooth plate, the gap of different sizes is applicable to the threshing of different cereal.Two cereal removal of impurities air-introduced machines coaxial with cylinder are arranged on the rear portion outside drum sieve, the vibrating screen surface.

The utility model has the adjusting device of regulating the gap between cylinder and drum sieve in separating mechanism, the size that can regulate the gap between cylinder and drum sieve is so can be suitable for the not threshing of cereal of the same race; Because cylinder is outward a drum sieve, can improve the efficient of threshing; Two cereal removal of impurities air-introduced machines coaxial with cylinder are arranged on the rear portion outside drum sieve, the vibrating screen surface in addition, can improve the cleanliness factor of threshing.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the partial sectional perspective view of multi-functional grain separator,

Fig. 2 is that partial sectional view is looked on the right side of multi-functional grain separator,

Fig. 3 is the rearview of multi-functional grain separator,

Fig. 4 is the enlarged drawing of I portion among Fig. 2,

Fig. 5 is the front view of the tooth plate of multi-functional grain separator.

Fig. 1; Fig. 2; among Fig. 3; multi-functional grain separator organic frame 1; frame has travelling wheel 13 1 time; be fixed with drum sieve 2 on the frame 1; be covered with cover cap 3 on the drum sieve 2; have in the drum sieve 2 and the cylinder 4 of drum sieve 2 on same axis; cylinder 4 has axis 5; tooth 41 by helical arrangement is arranged, the bottom of frame 1 on the circumference of cylinder 4; drum sieve has vibratory sieve 62 times, and the front end of drum sieve 2 has charging aperture 21; the rear end of drum sieve 2 have with the coaxial row's straw of cylinder 2 with centrifugal blower 22; sidewall at drum sieve 2 has cereal selector 7 vertically, and there are two cereal removal of impurities air-introduced machines 8 coaxial with cylinder at the rear portion outside cylinder on the vibrating screen surface.

Fig. 4, among Fig. 5, the cereal selector have along drum shaft to the tooth plate that tooth is arranged 71, a side of tooth plate 71 has axle 75 another sides that tooth 76 is arranged, on the sidewall of axle 75 in drum sieve 2 of tooth plate, cover on the wall of the cover cap 3 on the drum sieve, there is screw 72 on tooth plate 71 sides, be rotary with screw rod 73 in the screw 72, one end of screw rod 73 heads on tooth plate 71, the screw rod other end has crank 74, shake crank 74, screw rod 73 can be in screw 72 internal causes rotations and stretching motion, can promote tooth plate 71 around its 75 activity of marching forward in the footpath of drum sieve 2, thereby the gap that the side wall surface of adjusting cylinder 4 and tooth plate are 71, the gap of different sizes is applicable to the threshing of different cereal.
