Description

A kind of small-sized corn thresher

Technical field

The utility model relates to a kind of agricultural machinery, specifically is used for the machinery of corn ear threshing.

Background technology

Traditional small-sized corn thresher had not both had the corn ear feed quantity to reconcile mechanism and had not had corncob eliminating amount governor motion yet, thus can not adjust the productivity ratio of husker sheller according to corn ear water content difference, and influenced the threshing performance of corn kernel.

Summary of the invention

The utility model is the above-mentioned shortcoming that exists at traditional machine, and a kind of husker sheller that can improve the corn kernel threshing performance and improve labor productivity is provided.

The purpose of this utility model is achieved in that it has sheller unit, moving sieve cleaning plant, negative pressure cleaning plant, row's core apparatus and transmission device, it is characterized in that on the feeding mouth sidewall paneling of sheller unit corn ear feed quantity mediation board being housed, have an elongated hole on this plate plate body, be welded with a set bolt on the sidewall paneling, pass through wing nut, the feed quantity mediation board is fastened on the sidewall paneling, change the feed quantity mediation board with fastening wing nut and be fastened on upper-lower position on the sidewall paneling by unclamping, thereby reach the aperture that changes feeding mouth.When the corn kernel water content on the corn ear is big, the threshing difficulty, can turn the feeding mouth aperture down this moment, reduces the corn ear feed quantity, thereby guaranteed corn ear seed threshing performance; Otherwise, the corn kernel water content on corn ear hour, threshing is easy, can transfer the feeding mouth aperture big this moment, the corn ear feed quantity increases, and has improved labor productivity on the basis that guarantees corn ear seed threshing performance.Another effect of this mediation board is the effect that corn kernel that its back side both will sputter feeding mouth during to threshing plays a reflecting plate, the corn kernel reflected back threshing cylinder that splashes can have been reduced the corn kernel spatter loss.

Another feature of the present utility model is: row's core of the row's of being equipped with core apparatus wheel on the threshing cylinder main shaft, this device also has a core discharging outlet aperture adjustable plate, agitaion and the suitable core discharging outlet aperture adjustable plate of reconciling by row's core wheel, corncob after the threshing is discharged to smoothly to be reclaimed on the sieve, through reclaiming the shake effect of sieve, the corn kernel that is mixed in the corncob colony falls on the moving sieve compass screen surface that moves the sieve cleaning mechanism through reclaiming sieve, and corncob is discharged to outside the body.

The utility model can be according to what of corn kernel water content on the corn ear, and the openings of sizes of the feed quantity mediation board that is provided with on the sheller unit is adjusted, and can improve the threshing performance and the working (machining) efficiency of corn ear; The row's of setting core wheel can be enhanced productivity and crudy on row's core apparatus, is comparatively ideal corn ear threshing machine.

Embodiment

Sheller unit (see figure 1) of the present utility model mainly by receiving cone and feed quantity reconcile mechanism (1), threshing cylinder and main shaft (2), punching concave grate (3) is formed.Threshing cylinder and main shaft (2) by about two bearing blocks be fixed by bolts on the bearing-surface of the right support (31) of frame (4) and middle cross beam (5), the two ends connecting ring (28) of punching concave grate (3) respectively is fixed on right support side plate (16) and the middle cross beam side plate (6) by screw.

Row's core of row's core apparatus (see figure 3) of the present utility model wheel (8) is installed on the stage casing of threshing cylinder main shaft (2) by trip bolt (7), and its cover cap (9) is installed on the upper surface of the floor side member (12) of frame and front longitudinal (49) by two screws.Core discharging outlet adjustable plate (13) is actively connected on the lower edge of back stringer (10) with two pairs of foldings (11), aperture adjusting screw(rod) (18) is connected on the bottom of adjustable plate (13) by moveable hinge connection cover (14), the other end of aperture adjusting screw(rod) is fixed on the small branch plate (50) on the front longitudinal (49) by wing nut (51), when turning wing nut (51), then aperture adjusting screw(rod) (18) elongates or shortens, then spurring aperture adjustable plate (13) rotates around folding (11) axle center, then knockout mouth aperture changes size, realize the control of knockout amount, promptly control the time of corncob in sheller unit and retracting device, strive the corn kernel on the corncob all taken off and will contain the seed that is mixed in the corncob colony all reclaiming, reduce not threshing performance of corn kernel.Row's core wheel (8) is straight-tooth four impellers, and wheel tooth depth 8mm takes turns wide 100mm.Fall on the recovery sieve (17) through corncob and seed mixture that core discharging outlet is discharged, the frame of this recovery sieve (17) is welded on the frame of the sieve nest (26) of swinging cleaning plant by tee girder (15).

Negative pressure cleaning mechanism of the present utility model is a blower fan, and its blast fan (19) is six impellers, and it is fixed on the end of threshing cylinder main shaft by screw and flat key, the upper surface of the left socle (21) of fan hub (20) by being bolted to frame.

Moving sieve cleaning plant of the present utility model is an oscillating riddle that swings, and it mainly is made up of cleaning shoe body (26), suspension rod (24), toggle (41), oscillating stroke enlarger (36), crank axle bearing (43) etc.About two suspension rods (24) be movably hinged by Xiao's axle (25) that Xiao Taoyu is fixed on the tanker body (26) clearly respectively, upper end Xiao cover of suspension rod (24) is connected by Xiao's axle (22) moveable hinge with Xiao's axle bed (23) on being welded on sill side plate (6).The right-hand member middle part of cleaning shoe body (26) is welded with and connects axle bed (32), it connects by Xiao's axle (33) and oscillating stroke enlarger (36) are movable, the bearing axle seat of this mechanism (39) is welded on the bottom right needle beam A (37), Xiao's axle (38) is rotating support Xiao axle of oscillating stroke enlarger (36), the connecting rod of toggle (42) flexibly connects by Xiao's axle (40) and oscillating stroke enlarger, and the crank axle bearing (43) of this mechanism is fixed by bolts on the following needle beam B (44) of right support (31).Continuous by the electromotor (34) that is bolted on right support (31) fixed head by the bull wheel of electrical machine belt pulley (35) two pulley concial disks (27) of (29) drive cylinder shafts (2) end through the V-belt, cylinder shaft this moment (2) carries out threshing operations with the rotational speed of 1200r/min, and the steamboat of two vee-pulleys (27) drives vee-pulley (41) rotation of the crank axle head of toggle (43) by V-belt (30), has realized left and right sides reciprocally swinging by the then moving sieve cleaning plant of above-mentioned transmission mechanism.This machine belongs to corncob and tangentially feeds; it is dual clear grain function husker sheller with moving sieve cleaning plant and negative-pressure air-flow cleaning plant; its course of work is: corn ear is fed by receiving cone (1); through the effect of threshing cylinder (2) and punching concave grate (3) and threshing; corn kernel and the impurity separated from the punching concave grate drop to the moving sieve nest (26) of swing cleaning plant; moving sieve effect through swinging; the passive sieve of overwhelming majority impurity screens out; realized that corn separated with the first time of impurity; still the corn kernel that contains a small amount of lightweight impurity after clear is moved to the left at moving sieve effect lower edge compass screen surface; during through the inlet scoop of the blower fan of negative pressure cleaning plant; the light weight sundries that is mingled in the corn kernel is sucked away; air outlet by fan is discharged; thereby realized that impurity separated with the second time of corn kernel, reached the corn kernel of commodity food requirement this moment outside the afterbody discharge machine of sieve nest (26) is cleaned in swing.
