Abstract

PURPOSE:To enable labor saving in operation by blowing a blowing up wind from a blowoff port of a blower following the travel of a machine body along planted stand hill rows of rushes and turning up net parts where the rushes escape onto the planted stand rushes on the unreaped side. CONSTITUTION:A blowoff port 18 for blowing a wind from a blower 12 from the lower part on a net (N), spread on planted stand rushes and used for preventing the rushes from lodging and turning up the net to the unreaped land side is provided on a lateral part on the side of the unreaped land of a reaping pretreatment part 3 and a blowing up wind is blown from the blowoff port on the net following the travel of the machine body along the planted stand hill rows of the rushes. Net parts where the rushes escape are turned up onto the planted stand rushes on the side of the unreaped land to save labor in net turning up operation.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a rice straw harvester.

[Conventional technology]

In the cultivation of rush grass, nets were placed to prevent the produced rushes from falling over in any direction, causing damage, and preventing them from getting too entangled, and these nets were rolled up by hand at the time of harvest.

[Problem to be solved by the invention]

However, these nets are large and quite heavy, and lifting them up requires a great deal of effort, requiring several workers in addition to the operator of the harvester to remove the nets. .

The present invention has been made in view of these circumstances, and it is an object of the present invention to provide a rice straw harvester that can save labor in removing nets.

[Means to solve the problem]

In order to achieve the above object, in the present invention, a lateral part of the uncut field side of the pre-reaping treatment section, which is equipped with a rotary dividing rod and a pulling device that applies vibration to the planted grass, is provided with a The structure is such that the wind from the blower is blown from below onto the net to prevent lodging, which is hung on the net, and has an outlet that allows it to be flipped up toward the uncut land side.

[For production]

According to the above configuration, as the machine travels along the row of rush plants, the air blowing up from the outlet is blown onto the net. At this time, since the planted grass is vibrated by the 'it rotating dividing rod, the net is easily lifted up by the wind force towards the leaf tip side, and the grass is pulled downward against this lifted net. In this way, it receives the lifting action of the lifting device.

〔Effect of the invention〕

Therefore, according to the present invention, it is possible to smoothly turn up the difficult-to-handle net without putting strain on the grass, and it is possible to save labor by eliminating the need for a dedicated worker for removing the net, or by reducing the number of workers.

In particular, since the present invention uses wind to turn up the net while applying vibrations to the rush, there is no damage to the rush that would be expected in the case of, for example, a method of turning up the net by locking it with a machine, and the result is a high-quality product. It has the advantage of being able to harvest rushes with high efficiency.

〔Example〕

FIG. 1 shows a side view of the entire rice harvester, FIG. 2 shows a plane view thereof, and FIG. 3 shows a front view of its essential parts.

This rush harvester (A) has a self-propelled body (2) equipped with a crawler traveling device (1), and a reaping pre-treatment section (3) that can be freely adjusted up and down about a fulcrum (X) is connected to the front part of the self-propelled body (2). At the same time, it is configured such that a collection stand (4), a driving part (5>) and a vertical part (6) are mounted on a self-propelled aircraft (2).

The reaping pre-treatment section (3) includes a rotating weeding rod (7) that is driven to rotate at high speed in order to apply vibration to the planted rush grass (S) and untangle the rush grass (S); Grassed strawberry (
A triggering device (

A two-stage upper and lower cross-feeding device (11) that locks and conveys the part of the grass (S) towards the mown area from the clamping point, and blows wind at high speed on the side-feeded rush grass (S). A blower (12) for blowing the short interlayers contained in the conveyed rush grass toward the cut field side while raising it upward to the mowed field side, and a blower (12) for raking up the chopped rush grass (S) and displacing the part closer to the base of the plant from the pinching point. A locking and lifting device (13) that bends the body into a sideways posture? ! :
A selection belt (14) that combs and stretches the straw grass (S) that has fallen sideways from the leaf tip side to the plant base side, and sends out the interlayers toward the plant base side, and a selection belt (14) that pinches the sent out interlayers from above and below. A pair of upper and lower selecting rollers (15) are discharged to the outside of the machine, and a binding unit is used to bind the grass (S) lying on its side after the sorting process and rearward nipping conveyance and discharge it onto the collection table (4). The apparatus is equipped with a device (16), and is configured to cut and sort two rows of rush grass (S), then tie them together in a predetermined amount and collect them on a collection table (4) in a horizontal position. There is.

When reaping and harvesting using the rice straw harvester with the above configuration, it is necessary to lift up the net (N) that is hung over the planted rice grass (S) to prevent it from lodging. A means for flipping up is provided.

That is, as shown in FIG.
, (12b), one ventilation port (12a) is used for supplying the above-mentioned cleaning air, and the other ventilation port (12b) is connected to a duct).
(17) extends to the lateral outside of the lifting device (8), and its outlet (18) is set diagonally upward and outward. Therefore, the net (N) is blown upward by the high-speed wind blown out from this outlet (18), and the straw grass (S) is vibrated and is being subjected to the lifting action.
) The net (N) hanging on the net (N) is raised upwards, and the strawberry (S
) is raised by the raising device (8).

In the example, the wind for feeding and the wind for turning up the net are obtained from the same blower (12), but two blowers are installed in parallel on the same axis, and each blower is used exclusively for feeding and for turning up the net. It may also be carried out.

Incidentally, although reference numerals are written in the claims section for convenient comparison with the drawings, the present invention is not limited to the structure shown in the accompanying drawings.
