Description

A kind of grain header that reaping hook mechanism is housed down

Technical field

The utility model relates to agricultural machinery, further is meant the grain header that the reaping hook device is housed down.

Background technology

The full feed type rice/wheat combine of prior art, various large and small types no matter, all less than the following reaping hook mechanism of cutting at the reaping hook mechanism of the ceding of Taiwan that surplus standing grain stubble cuts off again is set, so these grain headers all can not cut off the standing grain stubble in the level land, can't realize straw incorporation.

The utility model content

The technical problems to be solved in the utility model is, at the defective that present technology exists, develops a kind of grain header that reaping hook mechanism is housed down, can the level land cuts off reaping hook and cuts surplus standing grain stubble, realizes the purpose of no-tillage plantation, straw incorporation; And can be the energy oscilaltion with this time reaping hook mechanism design, so that grain header can promote obstacle detouring when moving to another field, mound (promptly moving the field).

The technical solution of the utility model is, the described grain header that reaping hook mechanism is housed down comprises frame and is installed in this frame front and is provided with the header device of reaping hook mechanism, its design feature is that reaping hook mechanism and this time reaping hook mechanism are positioned at the back lower place of the described ceding of Taiwan under described frame front is provided with.

Below the utility model made further specify.

Referring to Fig. 1, the grain header that reaping hook mechanism is housed down described in the utility model comprises frame 1 and is installed in this frame 1 anterior and be provided with the header device 2 of reaping hook mechanism, its design feature is that reaping hook mechanism 3 and this time reaping hook mechanism 3 are positioned at the back lower place of the described ceding of Taiwan 2 under being provided with in described frame 1 front portion.Following reaping hook mechanism 3 adopts last reaping hook mechanism and the identical prior art structure of driving mechanism thereof with header device 2 to get final product.

Above-mentioned reaping hook mechanism down of the present utility model can cut surplus standing grain stubble with the header device of header device 2 and cut off once more in the harvesting operation.

As known from the above, the utility model is a kind of grain header that reaping hook mechanism is housed down, can the level land cuts off reaping hook and cuts surplus standing grain stubble, realizes the purpose of no-tillage plantation, straw incorporation; But the also oscilaltion of this time reaping hook mechanism is convenient to grain header and is being moved Tian Shike lifting obstacle detouring.

Fig. 2 is that down reaping hook mechanism 3 upwards lifts and operating position mounting structure figure when leaving cutting standing grain stubble.

Referring to Fig. 2, the described mounting structure of reaping hook mechanism 3 down is, transverse axis 6 is equipped with in frame 1 end face front portion, the upper end of right oblique arm 7 and left oblique arm 8 is hinged on the two ends of described transverse axis 6 respectively, and fixedly connected with the described respective ends of reaping hook mechanism 3 down respectively in the lower end of described right oblique arm 7 and left oblique arm 8, following reaping hook mechanism 3 two bottom sides respectively have downward opening location fork 9,10 correspondences to place on the wedge

shape rest pad

11,12 of both sides, frame 1 front end bottom and make thus that described down reaping hook mechanism 3 is supported, and this position also is the operating position during reaping hook mechanism 3 cutting standing grain stubbles down.Following reaping hook mechanism 3 assembly Design of length are for being 1050mm, and the operating position during cutting standing grain stubble overhead highly is 120mm.

The driving mechanism of following reaping hook mechanism 3 such as Fig. 2 are to shown in Figure 4.Referring to Fig. 2 and Fig. 3, driving wheel 13 of end fixed installation at described transverse axis 6, eccentric pin shaft 14 is housed on it, one end of connecting rod 15 is hinged with this eccentric pin shaft 14 and a crank arm end of 16 of same " L " type of its other end is hinged, 16 the position, turning of should " L " type cranking arm be hinged near on the described frame of reaping hook mechanism 3 one ends down and crank arm 16 the other end of " L " type connect with movable knife bar one end of reaping hook mechanism 3 down.It is that the eccentric pin shaft 14 on it is pressed arrow A among Fig. 4 with regard to drivening rod 15 that transverse axis 6 drive driving wheels 13 in Fig. 2 together rotate ₁, A ₂Direction is done back and forth operation, described connecting rod 15 by " L " type crank arm 16 drive under the movable knife bar of reaping hook mechanism 3 by arrow B among Fig. 4 ₁, B ₂Direction is done back and forth operation, realizes the harvesting action drives of reaping hook mechanism 3 down.

The described composition of the elevating mechanism of reaping hook mechanism 3 down is, middle part in following reaping hook mechanism 3 fixedly installs suspension ring 17 (as Fig. 1 or shown in Figure 2), at header device 2 bottoms corresponding installation suspension ring self-locking mechanism 18, installing between header device 2 and frame 1 front portion can be with the hydraulic jack 19 (referring to Fig. 1) of header device 2 jack-up; The structure of suspension ring self-locking mechanism 18 can be as shown in Figure 5, it comprises that the upper end is with the fixedly connected brace 20 in header device 2 bottoms, the upper end of suspension hook 21 is hinged with the lower end of this brace 20, the curved boom place of suspension hook 21 is terminal hinged with pull bar 22, the front end of pull bar 22 is connected on the control handle 5, be set with on the pull bar 22 with the fixedly connected drag link sleeve 23 in header device 2 bottoms, between pull bar 22 front ends and drag link sleeve 23, tension spring 24 be housed.

As shown in Figure 5, when pull bar 22 in this figure during the pull-up of upper right side, its suspension hook 21 is also by corresponding pull-up (establish be original position this moment, suspension hook 21 is thrown off with suspension ring 17); Primer fluid compressing cylinder 19 makes suspension hook 21 drop to the correspondence position of described suspension ring 17 with
