Description

A kind of corn combine

Technical field：

Belong to agricultural machinery technological field, and in particular to a kind of corn combine.

Background technology：

Corn combine is typically equipped with maize sheller, and sets bract seed in the lower section of apparatus for peeling off Grain recovering mechanism, to reclaim the seed that comes off that fruit ear occurs during harvesting, conveying, peeling etc., reduces loss.Existing bract Kernel recovering mechanism generally uses vibration sieve type, screw feeder screen mesh type, three kinds of structure types of scraper-type, comparatively, vibration sieve type It is complicated, but separating effect is preferably, and agitator type is simple and reliable for structure, but is separated when meeting larger impurity or big separation object amount Effect is substantially deteriorated, and when scraper-type works, scraper plate is moved in parallel, and the seed being wrapped in bract is taken away by scraper plate causes seed to damage Lose larger.

Therefore a kind of corn combine is urgently invented to overcome the problem of said mechanism device is present that there is reality to anticipate Justice.

The content of the invention：

The present invention is exactly that a kind of simple in construction, reliable operation, effect are provided to solve the problem of background technology is present Good a kind of corn combine, so as to improve the performance reliability and operating efficiency of complete machine.

A kind of corn combine, sets bow tooth to dial roll-type seed separating and reclaiming device, bow in the lower section of apparatus for peeling off Tooth dial roll-type seed separating and reclaiming device include frame, tail skid, front slide, the first group of roller, the second group of roller, the 3rd group of roller, point From screen cloth, impurity discharging port, kernel recovery box grain unloading mouth, actuating unit, tail skid is connected with separating screen, and separating screen goes out Mouthful end updip, front slide lower end is inserted second and third bow tooth and dialled between roller, three groups dial roll axis be horizontally arranged at by front and rear slide plate with In the separation chamber of separating screen composition, dial and moving tooth is welded with roller, impurity discharging port is connected to separation chamber rear portion, and kernel recovery box is in separation Under screen cloth, the position of its entrance sieve aperture on tail skid and separating screen, collection box bottom is provided with grain unloading mouth.

Wherein, tail skid the latter half is made of punching screen cloth.

Wherein, separating screen is made of punching screen cloth or steel-wire screen.

Wherein, front slide is made of steel plate.

Wherein, front and rear slide plate upper end spacing should be greater than and cover the effective length of peeling machine peeling rollers.

Wherein, moving tooth is arch and is staggered and does not wind.

Wherein, actuating unit uses chain or V-belt.

The solution have the advantages that：

Because the seed separating and reclaiming device of the corn combine of the present invention for bow tooth dials roll-type, its is simple in construction, Reliable operation, effect are good, so as to improve the performance reliability and operating efficiency of complete machine.

Brief description of the drawings：

Fig. 1 is part (bow tooth dials roll-type seed separating and reclaiming device) structural representation of the present invention；

Fig. 2 is Fig. 1 top view；

In figure：1. 2. tail skid of frame, 3. front slide 41. first groups, 42. second groups, roller the 3rd group of roller 5. of roller 43. The moving tooth of 8. transmission device of separating screen 6. impurity discharging port, 7. kernel recovery box 9.

Embodiment：

The corn combine that the present invention is provided, wherein bow tooth dial roll-type seed separating and reclaiming device, are installed on corn The lower section of combined harvester apparatus for peeling off, including 1 tail skid of frame, 2 front slide 3 first groups, 41 second groups, roller the 3rd group of roller of roller 42 The grade of 43 separating screen, 5 impurity discharging port, 6 kernel recovery box, 7 actuating unit 8 is constituted.

Frame 1 connects apparatus for peeling off above, is fixed on below on the big frame of cropper.

The latter half of tail skid 2 is made of punching screen cloth and is connected with separating screen 5, and isolate is needed through what apparatus for peeling off fell During landing, the segregative seed being mingled with can be pre-separated.

Separating screen 5 can be made of punching screen cloth or steel-wire screen, port of export updip, to strengthen separating capacity.

Front slide 3 is made of steel plate, and lower end is inserted between second and third bow tooth group roller, and front and rear slide plate upper end spacing should be greater than And cover the effective length of peeling machine peeling rollers.

Totally three groups of roller is dialled, axis horizontal is arranged in the separation chamber being made up of front and rear slide plate 2,3 and separating screen 5.Dial roller On be welded with moving tooth 9, moving tooth is arch and is staggered that push ability is strong and does not wind.

Impurity discharging port 6 is connected to separation chamber rear portion, for discharging the bract debris after separation in order.

Kernel recovery box 7 is under separating screen 5, and its entrance should exceed the position of sieve aperture on tail skid 2 and separating screen 5, Ensure that the seed that sub-argument goes out is entirely fallen in collection box.Collection box bottom is provided with grain unloading mouth.

Actuating unit can be using any mode that can guarantee that power transmission, such as chain, V-belt.

Operation principle：

Bract, broken stipe and the seed that corn combine apparatus for peeling off is peeled, which fall, to be entered between front and rear slide plate 2,3, Fall the easily separated seed needed in isolate on tail skid to fall to entering back by the sieve aperture of slide plate bottom during landing Case is received, remainder is slid on first group of roller, fall needs isolate to be slid along slide plate on second group of roller on front slide, dials Roller is driven by actuating unit and rotated counterclockwise, and will fall needs isolate to throw onto first group of roller on second group of roller, and rear Slid on slide plate need isolate together by first group of roller strap it is dynamic enter dial between roller and separating screen, each roller continuous action by its Promoted to impurity discharging port direction, needing isolate and dialling in roller contact process, needing isolate to be chosen by group roller bow tooth, tremble, tear work With, be mixed in seed therein and be separated, by sieve screen apertures fall enter kernel recovery box, the debris after separation is pushed to Impurity discharging port is discharged, and completes the separation and recovery of seed.
