Description

[Detailed description of the invention] Unexploded 1-1 is a flying aircraft equipped with all removal parts.
The entire process of reel and mowing process is m.
A mechanism that allows the priming Hi to be removed from the drive for one year, which is equipped with a device to transport and supply it to the handling area of the JJ removal section, and a mechanism that drives and lowers the NiJ raking reel relative to the reaping frame V of the reaping capital. The present invention relates to a DC combine harvester which is provided with:

Looking at reaping and harvesting work using this type of DC combine harvester, we find that at the beginning of cutting and during splitting, there is a bag VC in which the preceding stage forming rod is constantly pushed by the succeeding general culm. The backflow phenomenon to the side is suppressed by the formation rod itself,
Although the conveyance and supply action of the final stage grain culm to the membrane removal section side is carried out reliably, at the end of reaping ((at the end of the harvest), the harvested grain culm that controls the backflow prevention function disappears, There is a problem of backflow and spillage from Chengdu.

Also, is this kind of spilling of the mature general culm? Conventionally, as a means of suppressing the harvest, the reaping section is driven only at the same time as the reaping ends.
After raising the raking reel or lowering the raking reel against the reaping frame, continue mowing by and drive the entire section.
JJi: In the former case, the reaping section had to be raised until the conveyance path of the general culm became nearly horizontal, so the height of the reaping section had to be raised. There is a disadvantage that the outer grain is large and it takes a lot of time to raise and lower it, and in the latter case, the reaped husk is held down by the scraping reel, so the amount of E elevation of the reaping section must be minimized during work. Although it is possible to achieve the same efficiency, it requires lowering of the raking reel and raising of the reaping section.
There was a mermaid that was complicated to operate.

The purpose of the present invention is to adopt the latter method, which is advantageous in terms of work efficiency, while also making it possible to perform the operation fr=t-simply. A characteristic feature of the present invention is that a mechanism is provided for moving the raking reel drive elevating mechanism to the reel lowering side in conjunction with the lifting operation of the reaping section drive elevating mechanism.

f:, The action and effect of the feature configuration are as follows.

In other words, by simply performing the L raising operation of the reaping section, which is an essential operation at the end of reaping, the raking reel will first descend in conjunction with Vζ, so there is no need for any special operation for this purpose.
By adopting means to suppress cutting and spillage, which is advantageous in terms of work efficiency, it has become possible to simplify the operation of the 7th floor.

Hereinafter, embodiments of the present invention will be described based on the drawings.

To configure the DC combine harvester, Taro-2 traveling device + I
A traveling body (3) equipped with J and a rear free-rotating single wheel (2) is provided with a detachment section (4), a control section (5), and an engine tel, and the front part of the traveling body (3) is A reel (6) that scrapes into the tip side of the planted grain culm (6), a reaping device iM (71) that cuts off the root part of the husk that has been scraped (71), and The auger (8) that merges with the center of the 11 lateral VC machines and sends out the rear fC, and the shaft tip of the harvested grain culm are fully locked and the entire harvested grain IIX general culm is handled by the removal section (4) described in 071. Reaping section t equipped with a chain conveyor (an example of a conveyance supply device) (9) for conveyance and supply into M (4A)
lO+ is installed.

In addition, a mechanism (2υ and a mechanism +13 for driving the raking reel (6) up and down the reaping frame (12) K of the reaping unit (lO)) for driving the reaping unit tlol up and down with respect to the traveling machine body F31K is provided. It is set up.

The drive elevating mechanism for the reaping section (1) includes a hydraulic cylinder interposed between the reaping frame α and the traveling machine body (3), and an electromagnetic control pulp (16) that controls the expansion and contraction operation of this hydraulic cylinder. In the electric circuit, this L external solenoid (15a) and lowering solenoid R15b are installed.
) Fe Operation switch that can selectively energize and excite 1. I6
1, so that the entire reaping section can be driven up and down by selecting the operation switch and can be held fixed at a desired height position. A hydraulic cylinder H, tll19k is interposed between a pair of left and right swinging arms (I7) supporting the rotating shaft (6A) of the raking reel (6), and the reaping frame (+). In the electrical circuit of both hydraulic cylinders 1J8) and the electromagnetic control pulp 9) that controls the expansion of the country, there are external solenoid (19a) and lowering solenoid (x9).
b) An operation switch that can selectively energize and excite.

4 are interposed therebetween, so that only the scraping reel (6) can be driven up and down by selective operation of the operation switch 4, and can be fixed and held at a desired height position.

Therefore, a mechanism is provided that operates the VLS movable lifting wall structure for the raking reel to the reel lowering side in conjunction with the lifting operation of the drive lifting mechanism for the reaping section. The sensor (such as a potentiometer) continuously detects the amount of elevation of the reaping section 001 with respect to the traveling machine body (3).
) and the height setting 6 (c) for setting the outer silver, as well as the signals from both □□□ and q, and the reaping part (lO
) rises above the setting axis & Ch, the switch circuit 124
), a lowering solenoid (19b), and a comparison/discrimination circuit (c) that is energized and energized. Finished!
When turning the drive lifting mechanism for the reaping section (the operation switch (20)) (i-just operate the reaping section and the
When the reaping section (IO) rises above the cutting range, the raking reel (6) is automatically lowered. ) and outer grain as much as possible, in other words, suppressing the height to the minimum required for aircraft turning to improve work efficiency, while also preventing the grain culm from sliding off the reaping part (10). can be effectively suppressed.
