Description

[Detailed description of the invention] [Industrial application field] The present invention is a reel part of a combine harvester in which the inclination angle of the reel tine that scrapes grain culms at the front of the machine body can be adjusted according to the condition of the crop. The present invention relates to a reel tine angle adjustment device.

[Prior Art] Conventionally, in a reel portion of a combine harvester, a plurality of reel tines are suspended from substantially non-rotatable support rods that are horizontally suspended at predetermined intervals on the outer periphery between both rotating bodies. The structure was such that the inclination angle of the reel tines could be adjusted by changing the position of the center shaft of the entire reel.

[Problems to be solved by the invention] Therefore, since the reel as a whole is heavy, it requires unreasonable effort for elderly women and is difficult to adjust. The problem was that the angles of all the reel tines could not be changed uniformly.

[Means for solving the problem] The present invention solves the problem and makes it possible to adjust the angle of the reel tines reliably, quickly and easily.For this purpose, each support rod is made into a pipe, and each support rod is The upper end of each of the many reel tines is fixed to a support shaft that is mounted inside the shaft and is movable in the axial direction. A plurality of engagement grooves into which the reel tines can be engaged are formed on the end face of one of the long grooves formed in the circumferential direction of the rod on the side in the longitudinal direction thereof in the urging direction.

[Function] Therefore, by grasping one of the many reel tines arranged in parallel, the support shaft is moved slightly in the axial direction against the pressure, and the reel tine is supported while moving within the long groove. When the shaft is rotated to cause the reel tines to engage with the desired engagement grooves by elastic pressure, the tilt of all the reel tines arranged in parallel can be uniformly changed by rotating the support shaft.

[Example] Next, the embodiment shown in the drawings will be described.

Figure 2 shows a side view of the front part of the axial flow type combine harvester.The machine body supported by both crawlers 6 is equipped with a threshing section and a paddy tank B with a driver's cab 7 connected to the front side. The rear part of the reaping part A is connected to the threshing part side via the feeder part C, and the reaping part A has a raking auger 9 installed horizontally behind the cutting blade 8, and a reel part a above the front part. It will be erected and constructed in the same manner as the conventional structure.

In addition, the reel part a has six support arms 11a and 11b arranged on the inner side of both support arms 10a and 10b installed above both sides of the reaping part A.
Both rotary bodies 1a and 1b extending from each other are mounted on a shaft, and an arm 11a is attached to the central rotating shaft 12 of one of the rotary bodies 1a.
A sprocket chain 14 in a transmission cover 13 installed at A rotary body 1c which rotates eccentrically and driven by the rotary body 1a is installed close to the outside of the rotary body 1a, and arms 11c extend from positions equally spaced on the outer periphery of the rotary body 1c. One end of each short interlocking plate 15 is rotatably connected to the tip, and one end of each support rod 2 is fitted and fixed to the other end of each interlocking plate 15. It is constructed in the same way as the conventional structure by being constructed so that it revolves but does not actually rotate.

Each support rod 2 is made of a pipe, and a support shaft 4 that can be moved slightly in the axial direction by being supported by metals 16a and 16b on both sides is mounted at the center of the interior of each support rod 2, and one end of each support rod 2 A tension spring 17 that presses the support shaft 4 toward one side in the axial direction is fitted inside, and each support shaft 4
The upper ends of the reel tines 3 extending in the same direction are fixedly spaced apart from each other in the axial direction, and each support rod 2 is fixed so that a large number of reel tines 3 can be fitted therein.
A long groove 5 extending in the circumferential direction is formed on the circumferential surface of the groove 5, and five engaging grooves 5a are formed at intervals in the longitudinal direction on the longitudinal side of the long groove 5 on the one end side. .

Therefore, in each support rod 2, the reel tine 3 at one end is pulled into the engagement groove 5a by the tension spring 17.
When engaged with one of the reel tines 3, all the other reel tines 3 also hang in the same direction, and when the reel part a rotates as shown by arrow A, each reel tine 3 maintains a downward posture. However, it is possible to perform raking by acting on the planted grain culm in the same way as in the conventional type.

When the lodging state of the planted grain culm changes and the angle of each reel tine 3 is adjusted, grip one end of the reel tine 3, expand the tension spring 17, and move it in the direction of arrow B. This means that it can be removed from the long groove 5 and inserted into the long groove 5.
When the reel tines 3 are moved and fitted into other engagement grooves 5a as shown in FIG. 7, for example, all the other reel tines 3 in the same axial direction are operated in the same way, and the imaginary line shown in FIG. The angle can be adjusted as shown in .

[Effects of the invention] As described above, the present invention allows the reel tine 3 to be moved in the long groove 5 by gripping it and engaging it in the other engagement groove 5a while being pressed. This means that the angles of all other reel tines 3 can be adjusted in the same way, making it possible to adjust the angles reliably, quickly and easily without having to perform difficult operations like in the past. This means that the angles of all the reel tines 3 can be uniformly and favorably changed, and the present invention has the advantage that it can be suitably implemented with a simple structure.
