Description

[Detailed description of the invention] The present invention is provided with a feeding device that conveys the harvested rush in a standing position to the storage section, and also has a feeding device that conveys the grass from the cutting device by holding and conveying the grass from the cutting device in cooperation with the plant side clamping and conveying device and the ear side locking and conveying device. The present invention relates to a straw harvester configured to cause the feeding device to convey and feed in a standing position by operation.

This type of rice harvester, which transports the harvested straw grass to the storage section in a standing position, has the advantage that the length of the machine body is short from front to back, and that it is easy to align the ends of the plants. As a conventional technique, for example, a rice grass harvester described in Japanese Patent Application Laid-open No. 56-99715 has undulating claws arranged at predetermined intervals on a rotating chain as a means for raising planted rice grass and transporting the harvested rice grass by locking the tips. A single locking and conveying device is provided, the first half of which performs the lifting action, and the second half of which performs the action of transporting the tip.

The problem to be solved by the present invention lies in the above-mentioned locking and conveying device. Conventional conveying equipment consists of a rotating chain with undulating claws attached at predetermined intervals.
Since the raising speed and the tip conveyance speed are the same, there are problems such as tearing off heavily entangled grasses during raising, and conversely, the tip conveying speed is slow, leading to a decrease in work efficiency. Ta. In addition, since conventional undulating claws are generally rod-shaped, the area for locking the rushes is small and there is a problem in that they tend to damage the rushes. The present invention is an attempt to solve the above-mentioned problems, and it is possible to ensure that lifting is carried out, and also to allow harvesting in a state where tearing and damage that occur during lifting and transportation to a feeding device are less likely to occur. Moreover, the purpose is to simplify the structure for this purpose.

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

As shown in FIGS. 1 and 2, in front of a self-propelled aircraft equipped with a crawler-type traveling device 1, a driving unit 2, and a boarding type driving unit 3, a lifting unit 4 for planting thatch and a lifting unit are provided. A device 5 for cutting grass is provided,
A vertical conveyance section 6 for conveying the rush from the reaping device 5 to the rear of the machine body is provided on one horizontal side of the self-propelled machine body, and a pair of endless rotating bands 7, 7 that jointly hold and convey the rush side. , an endless rotating band 8 with a locking claw that locks and conveys the plant side, and is configured to horizontally convey the straw grass from the vertical conveyance section 6 to a gutter-shaped receiving storage section 9 in a standing position. A feeding device 10 is provided at the rear of the self-propelled machine, and a belt 11 having protrusions for combing the conveyed grass is provided on the conveyance path of the feeding device 10 so as to be freely driven and rotatable. The structure is such that short culms of a length less than a predetermined length that are not held by the bands 7, 7 are sorted out and released by falling, thereby forming a riding type straw harvester.

To construct the lifting portion 4, as shown in FIGS. 1 to 3, a pair of left and right frames 12, 12 are extended from the self-propelled aircraft to form a lifting path R, and the frames 12, 12, a weeding tool 13a or 13b for separating the planted grass into objects to be cut and objects not to be cut is fixed to the extending end of each of the grasses. A series of rotating shafts 1 configured to be driven by introducing power
5 is provided on one side of the pulling path R in an inclined state in which the tip part is located behind one of the weeding tools 13b and the level becomes higher toward the rear end, and the weeding tools 13a, 13b are A flat plate spiral body 16 for raising and acting on the grass to be harvested is attached to the rotating shaft 15 so as to rotate integrally therewith, and two guide rods are provided for preventing the grass from coming off the spiral body 16. 17, 17 are made to extend rearward along the spiral body 16 from behind the weeding tool 13a located on the opposite side to the side on which the spiral body 16 is disposed.

When configuring the vertical conveyance section 6, FIGS.
As shown in the figure, a portion 16b of the spiral body 16 located at the rear of the machine body than the reaping device 5 allows the tip side of the rush from the reaping device 5 to be connected to the endless rotation band 7.
A tip-side locking and conveying device is configured to transport and supply the tip end to the starting end of the reaping device 5, and is stretched from near the top of the reaping device 5 to the starting end of the endless rotating belt 8 with locking claws, and the endless rotating band 8 is stretched from near the top of the reaping device 5. A pair of endless rotating bands 19a and 19b driven by the power from the drive shaft 18 of the band 7 locks the root side of the rush from the reaping device 5 to the starting end of the endless rotating band 8 with a hook. A plant-side clamping and conveying device 19 is configured to lift and convey the grass from the reaping device 5 to the feeding device 10 in a standing position through cooperation between the spiral body 16 and the clamping and conveying device 19.

In the spiral body 16, as shown in FIGS. 1 and 2, the spiral pitch in the lifting action portion 16a is formed to be smaller than the spiral pitch in the portion 16b constituting the tip side locking and conveying device. Care has been taken to ensure that the pulling is carried out at a slow speed to prevent tearing even if the ropes are heavily entangled.

As shown in FIG. 4, the spiral body 16 is provided with an elastic body 20 for preventing rushes from coming into contact with the peripheral edge of the spiral body 16 and damaging it.

In summary, the present invention provides the above-mentioned rush harvester with a series of rotating spiral bodies 16 that pull up the planted rush and constitute the ear-side locking and conveying device, and a lifting-acting portion of the rotating spiral body 16. It is characterized in that the helical pitch in 16a is smaller than the helical pitch in portion 16b constituting the tip side locking and conveying device.

That is, since the lifting is forcibly performed by the rotating spiral body 16, the lifting can be performed reliably. Since the helical body 16 whose receiving surface for the rush is larger than the conventional rod-shaped locking claw is used for lifting and conveying the tip of the ear to the feeding device 10, there is no possibility that the culm will be damaged during lifting or conveyance. The lifting action portion 1 of the spiral body 16
Locking the pitch at 6a and conveying device component part 16
Since the pitch is smaller than b, even if the grass is heavily entangled, it can be pulled up slowly and gradually to prevent it from tearing. Furthermore, if the series of spiral bodies 16 are used for lifting and transporting the tip side, the transmission structure can be completed with a single system, so that the structure for lifting and transporting the tip side can be simplified in structure. Ta. Eventually, it became possible to produce crops at low cost that could be harvested without loss or quality deterioration due to uncut leaves or damage.
