Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a straw harvester,
In particular, it relates to a curdling device for stalks and culms.

[0002]

2. Description of the Related Art A conventional curling device for a seed straw harvester is constructed by mounting a curling lug on a belt as described in, for example, Japanese Patent Laid-Open No. 58-81709. . According to this configuration, the straw stalk culm is engaged with the currant lug moving in the direction of the plant base and subjected to the curling action, and the waste straw grass only in the swollen portion is removed, but the others are left behind. The overall action was insufficient.

Therefore, the straw culm of strawberries had a low commercial value and a low selling price.

[0004]

Since the curling device of the above-mentioned conventional straw-grass harvesting machine is based on currant rug, it is difficult to make the rug act uniformly on the whole straw-grass, and the rug acts. Although the waste mulberry weed was removed reliably, there was a problem that the waste mulberry remained in other parts.

[0005]

The present invention takes the following technical means in order to solve the above problems. That is, a holding and conveying device 3 that holds and conveys the upper portion of the mowed straw grass is provided on a chassis 2 having the traveling device 1, and the upper portion is held by the holding and conveying device 3 and the upper portion of the straw grass stem culm is being conveyed. A curling device 4 is provided for performing a curling action by acting on the root portion from the middle part, and the blower port 6 of the blower device 5 for causing the wind to act on the straw culm that is being curled by the curling device 4 is not seen. It is a straw harvester that is composed of.

[0006]

EXAMPLE First, the structure will be described. Chassis 1
Has a crawler 7 constituting the traveling device 1, a cutting device 8 is provided at a front lower position, and a cockpit 9 is provided at an intermediate portion. 10 is a weeding rod, 11 is a swinging weed body,
It is connected to the rocking rod 12.

Reference numeral 13 represents a stock-source scraping and conveying device. Reference numeral 14 denotes an upper scraping and conveying device, which has a scraping lug 15 and is provided so as to be inclined with its starting end positioned above the reaping device 8 and its terminal end positioned above the rear part. The vertical conveying device 16 is composed of a pair of left and right flat belts, and has a starting end portion located above the mowing device 8 and below the upper scraping conveying device 14 and an end portion extending to the rear part of the machine body.

The holding and conveying device 3 is constructed such that a pair of belts 17 and 17 'arranged on both sides can hold and convey the upper part of the straw culm, and the starting end portion is the upper scraping and conveying device 1 described above.
4 and the end portion of the vertical transport device 16 are faced to the intermediate position, and the end portion is provided so as to communicate with the binding device 18 on the side portion of the chassis 2. The curling device 4 includes the endless belt 19 and the curling lug 20.
Is provided and can be moved to the stocker side along the culm direction in the conveying path of the straw culm under the holding and conveying device 3.

That is, the endless belt 19 is used for the holding and conveying device 3.
Cursed rug 2 for straw grass stem culm being transported by
It moves while combing in the direction perpendicular to the transport direction with 0 interrupted, and removes the mixed straw and grass. The blower device 5 has a blower fan and has a vertical conveyance device 16
The hose 22 is attached to the case 21 and the hose 22 is extended to the curling device 4 side so that the blast nozzle 6 at the tip can blow from the tip side of the straw culm culm in the curling process to the root side. It is configured.

The prime mover 23 is provided below the cockpit 9 in a housed state so that the rotating parts of the machine can be transmitted via the transmission case 24. The reference numeral 25 is a cutter, which is configured to be able to cut the waste straw grass which has fallen from the curling device 4. Next, the operation will be described.

First, the prime mover 23 is started, and the harvesting work of the straw stalk culm is started while transmitting the rotating parts. Then, the straw stalks of the straw in the field are separated by 10
And is guided to the cutting row and is guided to the uncut side row (the next cutting). In this way, the straw stalk culm, in which the root part of the plant is weeded and guided to the cutting row, reaches the oscillating sward body 11 which is oscillated by the oscillating rod 12, and the upper parts thereof are brought into contact with each other to sequentially shunt And the upper part is separated left and right.

[0012] Then, the straw culm stems reach the stock source scraping and conveying device 13 and are scraped backward to reach the mowing device 8 to be cut. The mowed straw culm culms are held by the vertical conveyor 16 having belts 17 and 17 'at the base of the stock, and the upper part thereof is sequentially conveyed rearward by the scraping action of the upper scraping conveyor 14.

In this manner, the straw culm culms that have reached the rear portion of the chassis 2 are inherited by the start end portion of the holding and conveying device 3 located below the end portion of the upper scraping and conveying device 14 and held by the side. Be transported. In the above-described transportation process, the blower 5 blows the wind blown by the driven blower fan through the hose 22 to the curling device 4 from the jet port 6.

Then, the straw stalk culm reaches the curling device 4 in the above-mentioned state and passes across the endless belt 19 so that the currant lug 20 divides between the straw stalks and culms. While combing, it acts like a comb and separates the straw grass. At that time, the wind blown out from the blowhole 6 is the endless belt 1
It is sprayed on the straw culm on the upper part of 9 and blows to the root side, and not only the water droplets attached to the stem culm but also the waste straw are blown off at the same time.

As described above, the wind blown from the jet port 6 is
The curb lug 20 of the curling device 4 can blow away the waste straw grass separated from the stem culm and the waste straw grass adhered to the stem culm by wind pressure. As described above, the straw culm culm which has completed the curling action is fed from the terminal end of the holding and conveying device 3 to the binding device 18 and bound.

On the other hand, the waste straw grass separated from the straw stem culm is
It is supplied to a cutter 25 below the curling device 4 and cut.

[0017]

As described above, according to the present invention, a holding and conveying device for holding and conveying an upper portion of a mowed strawberries is provided on a chassis having a traveling device, and the upper portion is held by the holding and conveying device during conveyance. A blower opening of a blower device that provides a curling device that acts from the middle portion to the root portion of the straw grass stem culm to perform a curling action, and causes the wind to act on the straw culm culm that has been curled by the curling device. Since it is composed of the currant stalk, the straw culm is subjected to the wind while receiving the curling action of the currant rug, and the water droplets adhering to the straw culm are naturally caught between the straw culms. The waste straw grass in the abandoned state is also blown off at the same time, and effective curling action can be achieved.
