Abstract

The utility model relates to a front-mounted type harvester for haulm crops, such as corns, etc. The utility model can be matched with a wheel-type tractor with 10 to 25 horsepower. A reaping knife of the utility model is a horizontally rotating knife. A conveying auger is arranged transversally and horizontally, and the conveying direction is consistent with the rotating and throwing direction of the corresponding reaping knife. The auger is positioned above and in front of the reaping knife. Thus when the harvester is operated, the auger contacts a corn first, pushing the upper part of the corn forwards and inwards to the target, and then the end of the corn can be cut off by the reaping knife and thrown to the target. The corn falls down forwards, arranged in line. The utility model has the advantages of simple structure and regular inline.

Description

A kind of corn picker

The utility model relates to the grain header of stem stalk crops such as a kind of front-mounted type corn, can with the supporting use of wheel tractor.

The stem stalk of crops such as harvesting corn, harvesting earlier mostly, and then with holding up the standing grain star-wheel to pull over, many conveyer belts and stage clip are carried jointly, just can be sent to the position, the corn harvesting machine related as China's patent application 9520759.3 just adopts this method, but thisly cut the mode of afterwards sending earlier there are the following problems, complex structure not only, and because the corn highland barley is heavier, the center of gravity height, thereby be difficult to keep balance in the course of conveying, be difficult to the corn marshalling.

The utility model is that a kind of corn picker will be provided, and it can be with the corn marshalling of harvesting.

Task of the present utility model is achieved in that grain header mainly comprises conveying plant and reaping apparatus, and conveying plant is positioned at the top of the rotary cutting knife of reaping apparatus, it is characterized in that conveying plant is positioned at the A place, the place ahead of the rotary cutting knife of reaping apparatus.When grain header advanced with main frame, the conveying plant of stretching in the cropping knife front at first contacted the corn highland barley, its top was pushed put in place, and the cropping knife of rotation just cuts off its root then, and throws and deliver to the position, and corn falls down forward, thereby makes the corn stalk marshalling.

The cutter of reaping apparatus of the present utility model is made of the garden disc spins cutter of level (slightly leaning forward); Conveying plant is made of auger, and the auger transverse horizontal is provided with; Its throughput direction is thrown with the rotation of corresponding cropping knife front end and is sent direction consistent.The A place is preferably 30-50cm to the horizontal vertical distance of cropping knife.

The starting point of the present utility model is to send afterwards earlier to cut, thereby does not have the problem that makes the corn highland barley keep balance, thus hold up mechanisms such as standing grain star-wheel, stage clip to save, the auger that only adopts a horizontal cross to be provided with, thus simple in structure; In addition, to cropping knife its root is cut off, one section space-time is arranged as buffering, thereby the cornstalk that major part is toppled over also can be in place, makes the better effects if of embarking on journey owing to touch the corn highland barley from auger.

Below just reach specific embodiment in conjunction with the accompanying drawings, the utility model will be further described.

Fig. 1 is the end view according to the grain header that the utility model proposes.

Fig. 2 is the front view of Fig. 1 grain header.

With reference to Fig. 2, present embodiment is a kind of duplicate rows grain header.

With reference to Fig. 1, grain header is incorporated into by quiet bar (1) on the front bumper (2) of tractor, by the lift arm of steel wire rope (3) connection tractor, with the lifting of control grain header.(5) be the frame of grain header.

With reference to Fig. 2, cropping knife (6) is fixed in the lower end of axle (18), axle (18) is incorporated in the hollow shaft (17) with a gap, the two is slidingly connected by helical spline (21) and the key (20) that is incorporated on hollow shaft (17) inwall, the direction of rotation of hollow shaft (17) must with helical spline (21) lower end around to consistent, it is inwardly rotation of cropping knife (6), be compressed with spring (10) on the axle (18) between the lower end of hollow shaft (17) and the cropping knife (6), its two end is pressed with the sleeve (12) of anti-careless wing, upper end sleeve (12) is fixed in the lower end of hollow shaft (17), and following sleeve (12) is incorporated on the axle (18) with a gap.Two fins (11) of anti-careless wing are fixed in two sides of sleeve (12) symmetrically.

With reference to Fig. 1, main frame power is driven dihedral gear (13) and is rotated counterclockwise by axle (4) input, and with reference to Fig. 2, dihedral gear (13) drives inwardly rotation of cropping knife (6) by gear (14), (16), (15), hollow shaft (17), axle (18).Gear (13) drives inwardly rotation of cropping knife (6 ') by gear (19), belt wheel (22), (24) and hollow shaft (17 '), axle (18 ').Gear (13) drives auger (8) by gear (14), belt wheel (25), V-belt (9) and belt wheel (23) and is rotated down, and inwardly pushes, and with reference to Fig. 1, auger (8) is to turn to (7) rotation.L is preferably 30-50 centimetre.

With reference to Fig. 1, when grain header marched forward with C, the auger of stretching at the A place (8) contacted the corn highland barley earlier, pushes away it curved forward, because auger is to turn to (7) rotation, with reference to Fig. 2, auger (8) inwardly pushes the corn highland barley, and its top is pushed away in the centre position, this moment, inwardly the cropping knife (6) of rotation just cut off corn root, and its root thrown between two cuttves, corn falls down forward, is in line between two cropping knifes (6).

Claims (5)

1. The grain header of 1 one kinds of cane crops such as front-mounted type corn, mainly comprise conveying plant and reaping apparatus, conveying plant (8) is positioned at the top of the rotary cutting knife (6) of reaping apparatus, it is characterized in that conveying plant (8) is positioned at the A place, the place ahead of the rotary cutting knife (6) of reaping apparatus.
2. 2 grain headers according to claim 1 is characterized in that the cutter (6) of reaping apparatus is made of the rotating circular disk cutter that level slightly leans forward.
3. 3 grain headers according to claim 1 is characterized in that conveying plant is made of auger (8) transverse horizontal setting auger (8).
4. 4 according to claim 1 or 3 described grain headers, and it is consistent that the direction of sending is thrown in the front end rotation that it is characterized in that the throughput direction of auger (8) and corresponding cropping knife (6).
5. 5 grain headers according to claim 1 is characterized in that the A place is 30-50 centimetre to the horizontal vertical distance L of cropping knife (6).
