Description
Technical field
The utility model relates to a kind of whole combine that is fed into sheller unit of crop (paddy stalk) with harvesting, claims all feeding-in combine again.
Background technology
All feeding-in combine is that whole the feeding carried out the grain header that threshing is gathered in after cutting off by the cane with crops such as rice wheats in the body.All feeding-in combine comprises traveling machine body, traveling machine body moves by installation crawler belt or wheel below body, the front portion of traveling machine body is provided with and can be made for the operating desk that the industry personnel operate grain header, the place ahead of operating desk is provided with the ceding of Taiwan that is movably connected on traveling machine body and can controls its lifting by hydraulic jack, the forward position, bottom of the ceding of Taiwan is provided with cutter, and ceding of Taiwan top is provided with by hydraulic jack controls the device of taking off its lifting and rotating.
When gathering in operation, taking off device rotates towards the machine direct of travel, to be taken off the rear of the ceding of Taiwan by the rice wheat that cutter cuts off cane, ceding of Taiwan rear is communicated with threshing portion on being arranged at traveling machine body by feeding portion, taken off rice wheat cane that device takes off ceding of Taiwan rear and focus on feeding portion front end by the feeding auger that is arranged on ceding of Taiwan rear and refer to send feeding portion to by taking off of feeding auger, feeding portion sends rice wheat cane to threshing portion and carries out threshing.Finish threshing cane afterwards and get rid of from the outlet at threshing portion rear, grain is then collected grain collecting box.
But the harvesting mode of this full feeding need feed threshing portion together with the cane and the rice wheat head, in order not influence cultivating next time, stay in the ground cane cut stubble should be short more good more, in order to reduce the cane cutting height, it is very low that the ceding of Taiwan must need to put, this will cause the feed quantity of threshing portion very big, and the threshing load increases, and also can increase the difficulty of threshing and reduce threshing performance.
In order to address the above problem, more existing combines are provided with lower cutter device, as Fig. 1 to and shown in Figure 3, it comprises the front end below that is positioned at feeding portion 1 and is connected cutting mechanism on the walked frame 3 by three linking arms that are arranged in parallel 2, but cutting mechanism comprises fixation kit 4 and the reciprocating moving knife assembly 5 in relative fixed assembly 4 left and right sides, said fixing assembly 4 comprise knife rest 41 and a plurality of about be arranged in guard 42 on the knife rest 4 to the interval, above-mentioned moving knife assembly 5 comprise can be in guard 42 the reciprocating moving knife bar 51 in the left and right sides, be riveted on the following cutter 52 on the moving knife bar 51, and being screwed onto tooth plate 53 on the moving knife bar 52, tooth plate 53 can be dredged the long-pending grass that is positioned at knife rest 41 upper surfaces.Described linking arm 2 is connected with operating grip on being arranged on operating desk 7, and the operator can regulate the height of cutter 52 down by the operating grip on the operating operation platform 7.
When grain header carries out operation, the ceding of Taiwan can be raised, thus the feed quantity of reduction cane, reduce the load of machine, improve the efficient of threshing, following cutter then reduces as far as possible, the height that cuts stubble is reduced as far as possible, as much as possible cane is stayed enter grain header in the ground and not.
But in practice, the linking arm that is arranged in the centre position in three linking arms of knife rest is in long-term use, its with the link position of knife rest on long-pending easily careless, when long-pending grass covers down on the cutter, can hinder it that cane is cut off, make the following cutter that is positioned at middle linking arm position lose efficacy.
Summary of the invention
The utility model purpose is: the lower cutter device that a kind of combine is provided, its moving knife assembly is provided with grass scraping plate in the position corresponding to the middle part linking arm, during moving knife assembly working in reciprocating mode, the grass scraping plate movement therewith, avoided occurring on the link position of middle part linking arm and knife rest long-pending careless, guaranteed that the moving knife assembly can effectively work.
The technical solution of the utility model is: a kind of lower cutter device of combine, comprise the front end below that is positioned at feeding portion and be connected cutting mechanism on the walked frame by linking arm, but cutting mechanism comprises fixation kit and the reciprocating moving knife assembly in the relative fixed assembly left and right sides, the said fixing assembly comprise knife rest and a plurality of about be arranged in guard on the knife rest to the interval, above-mentioned moving knife assembly comprise can be in guard the reciprocating moving knife bar in the left and right sides, be riveted on the following cutter of moving knife bar, and being screwed onto tooth plate on the moving knife bar, tooth plate can be dredged the long-pending grass that is positioned at the knife rest upper surface.
Described moving knife assembly is provided with grass scraping plate corresponding to the position of middle part linking arm, and during moving knife assembly working in reciprocating mode, the grass scraping plate movement therewith has been avoided occurring on the link position of middle part linking arm and knife rest long-pending careless, has guaranteed that the moving knife assembly can effectively work.
To the careless portion of vertical retaining of extending and keep off the installation portion of careless portion perpendicular to this, described installation portion was fixed on the above-mentioned tooth plate before and after described grass scraping plate had.For convenience of installing and fixing between grass scraping plate and the tooth plate, described tooth plate is installed the width that the double wedge that cooperates is wider than other double wedges with grass scraping plate.
The utility model has the advantages that:
1. moving knife assembly of the present utility model is provided with grass scraping plate in the position corresponding to the middle part linking arm, during moving knife assembly working in reciprocating mode, the grass scraping plate movement therewith has been avoided occurring on the link position of middle part linking arm and knife rest long-pending careless, has guaranteed that the moving knife assembly can effectively work.
2. described tooth plate is installed the width that the double wedge that cooperates is wider than other double wedges with grass scraping plate, has made things convenient for installing and fixing between grass scraping plate and the tooth plate.
