Description

[Detailed Description of the Invention] This invention relates to a cutting and stem conveying device for a harvester for rapeseed or similar crops (hereinafter referred to as rapeseed).

In rapeseed, the volume of the upper part of the plant stem varies greatly depending on the condition of the rapeseed part, so this difference has a large effect on the transportation and collection posture, which tends to result in cases where collection is not carried out in an orderly manner. Therefore, the present invention has been devised to provide a harvested grass stem conveying device for a rapeseed harvester that can be adjusted and used to collect grass stems in an orderly manner with an extremely simple change operation even when cutting and collecting grass stems of different conditions. This is what we intend to provide.

That is, the structure is such that the cut grass stalks are transferred and discharged in a horizontal position to the collecting section by a conveying device consisting of a lower clamping transfer mechanism and an upper clamping transfer mechanism, and the transfer end of the lower clamping and transporting mechanism is connected to the upper clamping transfer mechanism. The present invention is characterized in that the relative position of the pulling transfer mechanism to the transfer end can be changed and adjusted in the transfer direction.

0... stands up and protrudes outward at the lower end of the casing, moves upward on the front upper surface of the casing 17, and is housed in the casing at the upper part, and the support of the casing 17 is as follows. This is done by support members 21 and 22, and the chain is driven by a transmission mechanism 23 interlocked with the separation drive shaft 15.

Frame component 1 at the lower rear of the entanglement separating device E
A reciprocating type cutting blade device 24 is horizontally installed between 2a and 12b, and the device 24 is interlocked and connected so as to be operated by the reaping drive shaft of the reaping conveyance drive case 14 described above. From the front upper part of 24 to the rear diagonal upper part, the transport device A
The device A includes a pair of left and right scraping mechanisms 25a, 25b and 26a, 26b, and a lower conveyance mechanism 27 consisting of a chain conveyance mechanism connecting these with a sandwiching conveyance path;
The transport mechanism 28 is comprised of an upper suspension conveyance mechanism 28 installed appropriately above the transport mechanism 28.

As seen in FIG. 2, the lower conveyance mechanism 27 and the upper conveyance mechanism 28 have a conveyance path that is a curved path with a shape, and the cut grass stalks are held in a substantially horizontal position at the end of the conveyance. While lying on its side, move the collection section D mentioned above.
The lower conveyance mechanism 27 is driven by the output shaft of the reaping conveyance drive case 14, and the scraping mechanisms 25a, 25b, 26a, 26b are One of the output shafts 25a and 26a is driven, and the other is synchronously transmitted by meshing with 26a and 26b, and the upper engaging conveyance mechanism 28 is driven via one shaft 29 of the lower conveyance mechanism 27. Moreover, the vertical position of the upper latching conveyance mechanism 28 is configured to be able to be changed or adjusted within an arbitrary range by the telescopic structure of the single shaft 29 and the support position changing structure by the supports 30, 30.

Further, the upper latching transfer mechanism 28 is connected to the case body 36.
Engagement protrusion 3 attached to the chain wound and tensioned inside
2... are made to stand up and protrude in the conveyance path, and the lower conveyance mechanism 27 is configured so that the upper part of the plant stem, such as rapeseed, can be conveyed by being engaged between the protrusion and the guide rod 33. The conveyor chain 34 with projections and the clamping rods 35 attached thereto are configured to be able to clamp and transport the grass stems.

Conveyance chain 3 with protrusion in lower conveyance mechanism 27
4 is a wheel body 37 supported by 6 to the chain stand;
38, 39 and idlers 40, 41, and the wheel body 39 and idler 41 located at the end of the transfer path are moved by the position change adjustment mechanism 4.
2 and 43, respectively, so that the position of the end of the transfer end of the conveyance chain 34 with projections relative to the upper latching transfer mechanism can be changed and adjusted in the transfer direction. Correspondingly, the end portion of the clamping rod 35 is configured so that it can be adjusted to protrude and retract by means of a telescopic fixing mechanism 44.

The tangle separating tool E located at the rear of the weeding body 16a loosens the tangles between the grass stalks within the reaping action range and the grass stalks outside the reaping action range by lifting the separating protrusions 20... The cutting blade device 2 uses mechanisms 25a, 25b, 26a, and 26b to scrape grass stalks.
4, and held by the lower conveyance mechanism 27 and the upper engaging conveyance mechanism 28, and the cutting blade device 24 cuts the stock at its base.

The cut grass stalks whose base portions have been cut are then transported rearward and upwardly by both of the above-mentioned transport mechanisms 27 and 28, and are then discharged into the collection section D from the transport end of the transport path that bends in the shape of a shape. The release position at this time is a sideways position with the upper part of the single stem located in front of the vehicle body.

Then, when reaping plants with different levels of fruit, if the collecting posture of the grass stems discharged to the collecting section D is not good, the position change adjustment mechanisms 42 and 43 are operated to Transport mechanism 2
The protruding chain 34 at 7 is changed to, for example, the state shown in 34a in FIG. Transport mechanism 2
The transfer direction is appropriately changed and adjusted with respect to the transfer end portion of No. 8 so that the cut grass stalks are discharged to the collecting section D in a good posture.

In addition, when cutting grass stems of different heights, the upper conveying mechanism 28 is adjusted in the vertical direction to adjust the distance between it and the lower conveying mechanism 27. This allows the paper to be transported while being held at two suitable positions in both directions.
