Description

[Detailed description of the invention] The present invention has a spiral structure that raises the planted stem culm so that the planted stem culm can be forcibly pulled up in a state where the receiving surface for the culm is large and the culm is less likely to break. The present invention relates to a lifting device for a reaping harvester equipped with a rotating body.

In the above-mentioned harvesting machine, conventionally, the planted stem culm may lie down toward the front of the machine or on the opposite side of the spiral rotating body, or may be far away from the spiral rotating body, depending on the lodging direction or the planting position. As a result, the culms of the planted stems were less likely to be caught by the helical rotating body, making it more likely that they would be pulled up incorrectly or pushed down.

The purpose of the present invention is to be able to reliably lock the planted stem culm to the helical rotating body even if it is lying down in any direction or away from the helical rotating body, and to ensure that it can be lifted and transported reliably. The object is to ensure that the lifting operation is carried out in such a way that the lifting operation is carried out reliably, and to enable the work to be carried out without pushing down.

A characteristic configuration of the pulling device of the reaping and harvesting machine according to the present invention is that a locking device is provided on the side of the pulling path to scrape the planted stem culm into the spiral rotating body and transport it in cooperation with the spiral rotating body. In a state in which the endless rotating belt-like body with claws is disposed on the opposite side of the spiral rotating body, and the pitch in which the locking claws are parallel in the longitudinal direction of the endless rotating belt-like body is the same as the helical pitch of the spiral rotating body. Further, the locking pawl is provided in a state in which the locking pawl overlaps the helical rotary body when viewed in the axial direction of the helical rotary body.

Even if the planted stem culm is lying in a direction where it is difficult to be caught by the spiral rotating body or is away from the spiral rotating body, the stem base is attached to the spiral rotating body by the locking claw so that it is caught on the spiral rotating body. This is made possible by the endless rotating belt-shaped body with a locking pawl. Moreover, the raked stem culm is reliably lifted and conveyed by the cooperation of the spiral rotating body and the locking claw, and furthermore, this cooperative lifting and conveyance acts over a relatively long part of the culm. In order to ensure that the stem culm is securely locked to the helical rotating body without delay and that the pulling action on the locked stem culm is reliably performed, the locking claw is This is made possible by the fact that it has an endless rotating band and that the locking pawl wraps with the helical rotor at the parallel pitches. As a result, it has become possible to reliably raise the plants and harvest them without pushing them down, regardless of the planting state.

Embodiments of the present invention will be described below with reference to the drawings.

On one horizontal side of the self-propelled machine body, there is provided a lifting and reaping section 4 for the planted grass, a vertical transport section 5 for the cut grass, and a pair of upper and lower endless rotating bands 6a, 6b for holding and transporting the cut grass. It consists of an endless rotating band 7 that locks and conveys the stock end side of the rotating bands 6a, 6b, and an endless rotating band 8 that locks and conveys the tip side of the ear while combing the rotating bands 6a, 6b. A horizontal conveyance section that transfers the grass from the vertical conveyance section 5 in the lateral direction of the machine body, which acts to comb the grass transferred by this horizontal conveyance section, and selects short culm grass that is not pinched by the rotating bands 6a and 6b to the rear of the machine body. an endless rotating band 9 with a protrusion, a chute 10 that guides the grass selected by the rotating band 9 to fall to one side of the aircraft body;
Containers 11 for collecting and storing rushes with longer culms than the set length from the horizontal conveyance section are provided on the upper part of the self-propelled body, thereby forming a rush harvester.

The lifting reaping section 4 is constructed as shown in FIGS. 3 and 4.

In other words, from the self-propelled aircraft, a pair of left and right frames 1
2 and 12 to form a raising path R,
A weeding tool 13 for dividing the planted grass into objects to be cut and objects not to be cut is fixed to the extending end of the frame 12, and a cutting device 14 is arranged at the back of the pulling path R. and a rotating shaft 17a configured to be driven by a transmission case 16 in conjunction with the driving rotating shaft 15 around which the starting end of the upper endless rotating band 6a is wound; The pulling helical rotating body 17, which is made up of the attached spiral band plate 17b, is pulled up in an inclined position with the front end located near the ground in front of the reaping device 14 and the rear end being located at a higher level. A pair of upper and lower rods 18a and 18b are arranged on one side of the path R and prevent the grass from coming off the spiral rotating body 17.
A chain case 19 is located on the opposite side of the spiral rotating body 17 and is fixed on the side of the lifting path R.
The grass from the weeding tool 13 is forcibly pulled up while being received and locked on a relatively wide surface by the spiral rotor 17. In this state, the base of the stock is cut by a reaping device 14.

Further, as shown in FIGS. 3 to 5, the base of the planted rush is scooped up and scraped into the starting end of the spiral rotor 17, and the scraped rush is moved in cooperation with the spiral rotor 17. A plurality of locking pawls 20 that are pulled up and transported by the action of the chain case 19 are divided into a lower part and an upper part in the chain case 19. The endless chain 21 is wound around a pair of sprockets 22 and 23, and the parallel pitch of the locking pawls in the longitudinal direction of the endless chain 21 is formed to be the same as the helical pitch of the helical rotating body 17. Then, the protrusion of the rotating shaft 24 supporting the upper sprocket 22 to the outside of the chain case 19 is connected to the transmission belt 2.
