Description

[Detailed Description of the Invention] The present invention relates to a pulling section of a reaping/harvesting machine that is provided with a rotating spiral body for raising planted stem culms so that damage caused by pulling up the stem culms is less likely to occur.

Conventionally, in the above-mentioned pulling part, in order to ensure that the spiral body acts on the stem culm, as shown in FIG. 17, and if the pulling stem culm is intertwined with a stem culm located in front of the helical body on the plant base side and the pulling resistance becomes large, the pulling stem culm will move against the spiral body. Since it is difficult to slip through and move toward the starting end side, it has the disadvantage of being easily torn.

The present invention reliably prevents the stem culm from coming off the helix when the lifting resistance is relatively small, but when the lifting resistance increases abnormally as mentioned above, The purpose is to allow the stem culm to easily slip through and move against the helical body, thereby ensuring that the lifting action is performed under normal conditions, while also preventing tearing during abnormal conditions. .

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

As shown in FIGS. 1 and 2, a control handle 3 is moved forward from a self-propelled aircraft equipped with a pair of left and right running wheels 1, 1 and an engine 2 mounted in front of these wheels 1, 1. A transport unit 6 is provided in front of the self-propelled body to extend and transport the harvested grass, and a raising part 4 for the planted grass and a reaping device 5 for the raised rice grass are provided in front of the self-propelled body.
is provided on one horizontal side of the self-propelled machine, and an endless rotation belt 7 that transports the grains horizontally while combing the tip side, and a pair of endless rotation belts that jointly hold and transport the stock end side from the rotation belt 7. Moving belts 8, 8, an endless rotating belt 9 that locks and transports the plant side of these rotating bands 8, 8, imparts a combing action to the straw transported by these rotating bands 7, 8, 9, and It consists of endless rotary belts 10 each with a protrusion for sorting and taking out short culm grass that is not held by the endless rotary belts 8 and 8 to the rear of the machine body, and sorting the grass from the conveying section 6 while conveying it horizontally, and separating it from the set length. Short culm straw grass is discharged along the chute 11 to the side of the aircraft, and long culm straw grass with a length longer than the set length is discharged to the trough-like storage device 12.
A sorting and conveying section configured to feed rice to rice is provided above the self-propelled body, thereby making up a straw harvester.

To construct the lifting portion 4, as shown in FIGS. 1 to 4, a pair of left and right frames 13, 13 are extended from the self-propelled body to form a lifting path R, and The frame 1 includes a weeding tool 14 that separates rush grass into objects to be cut and objects not to be cut.
Two rotary shafts 16a and 16b are fixedly installed at the extending ends of each of the two rotating shafts 16a and 16b, and are configured to be driven by introducing power from the endless rotation band 3 through the transmission case 15, and the front end thereof is connected to the weeding tool 14. are located behind the weeding tools 14, 14, and arranged side by side in a state where the rear end side is located at a higher level and are located separately on both sides of the pulling route R, and the planted rice grass from the weeding tools 14, 14 is arranged in parallel. The two flat spiral bodies 17a and 17b for causing the
As shown in the drawings and FIG. 4, the two rotating shafts 16a,
16b and are attached so that they can rotate together.
That is, the grass to be cut, which is divided by the weeding tool 14 and introduced into the pulling path R, is sandwiched between one spiral rotating body 17a and the other spiral rotating body 17b, so that it does not come off from the spiral rotating bodies 17a and 17b. It is designed so that it can be lifted up and transported.

As shown in FIGS. 1 and 2, the conveying section 6 is configured such that the portions of the helical bodies 17a and 17b located at the rear of the reaping device 5 move the rush from the reaping device 5 to the tip side. A pair of endless rotary movable shafts are connected to each other and extend from near the top of the reaping device 5 to the rear end of the sorting and transporting section. By the bands 18a and 18b, the reaping device 5
A plant-side clamping and conveying device is configured to lift and transport the stalk side of the rice straw grown from the plant, and furthermore, between this plant-side clamping and conveying device and the spiral bodies 17a and 17b, the middle part of the culm is transferred to the sorting and conveying section. An endless rotating belt 19 is provided in the middle part for lifting, locking and conveying, and the straw grass from the reaping device 5 is transferred to the spiral bodies 17a, 17b and the endless rotating belt 19.
By the cooperation of the plant side clamping and conveying device, the stalks are lifted and conveyed, and the tip of the stalk is located at the front side of the machine, and the culm changes its posture to a lying position along the longitudinal direction of the machine.In this lying position, the sorting and conveying section It is designed to be supplied to

At the installation part of the reaping device 5, as shown in FIG.
Three star foils 20... are arranged in parallel in the longitudinal direction of the fuselage, and as shown in FIG.
The rotating spindle of the endless rotating band 18a is interlocked with the winding rotating shaft of the endless rotating belt 18a, either directly or by a belt, so that each star wheel 20 can be driven. It is intended to ensure that the rush is supplied to the endless rotating belts 18a and 18b.

In providing both the spiral bodies 17a and 17b, a seventh
As shown in the figure, the rice grass may be arranged diagonally in the vertical direction of the machine so as to be raised in an inclined state with the tip side located on the sorting and conveying section side.

The above-mentioned raising part 4 is extremely useful when used for harvesting rice grass, for which damage to the culm is fatal, but it can also be applied to various harvesting machines such as a combine harvester.

In summary, the present invention has two rotating spiral bodies wrapped in the pulling section of the reaping/harvesting machine mentioned above in the axial direction, and positioned separately on both sides of the pulling path, so that the stems to be pulled are Since the culm is sandwiched between one rotating helical body and the other rotating helical body and is pulled up and transported in parallel, under normal conditions when the lifting resistance is relatively small, the culm is held in parallel with one of the helical bodies 17a or 17b. Since the other helical body 17b or 17a reliably prevents the stem from coming off, the culm can be pulled up reliably, but if the pulling resistance increases abnormally as described above, the stem culm will Since it easily slips through the gap between the spiral bodies 17a and 17b toward the starting end, tearing becomes less likely to occur.
