Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is to install several blades for cutting crops such as corn and grass in a cylindrical shape around the blade rotation axis. The present invention relates to a crop feeding device in an up-cut type cylinder-type harvester that cuts crops at a portion that is rotating upward.

[Conventional technology]

FIGS. 6 to 10 show a conventional harvesting device for a cylinder type harvester.

A blade mounting metal 4 around the blade rotating shaft 2 supported horizontally.
Several blades 6 are attached via the, and this is housed in a blade case 8. A harvested material receiving port 12 is provided on the front surface side of the peripheral wall 10 of the blade case 8, and a cut product in which the harvested material A is cut is discharged to the side of the peripheral wall 10 where the harvested material receiving port 12 is provided. A cutout discharge port 14 is provided for cutting, and a chute 16 is provided in the cutout discharge port 14.
Are connected and provided.

The blade case 8 is composed of a peripheral wall 10 and a side wall (not shown), and the inside thereof is a cutting chamber 18 for the harvest A.
The blade rotating shaft 2 rotates in the arrow P direction in the cutting chamber 18.

Harvest receiving port 12 provided on the peripheral wall 10 of the blade case 8
A pair of feeding rolls 20a, 20b for feeding the harvest A to the cutting chamber 18 is provided on the front side of the above in a substantially vertical direction.

The rotating shaft 22a of the upper feeding roll 20a is attached so as not to move up and down, but the rotating shaft 22b of the lower feeding roll 20b has a distal end portion of an arm 26 whose base end is pivotally attached to a fulcrum shaft 24. The arm 26 is urged upward by a tension spring 28. Therefore, only the lower feeding roll 20b is vertically moved around the fulcrum shaft 24.

A large number of tooth-shaped feeding members 30 are axially provided on the outer peripheral surface of the upper feeding roll 20a, and a large number of feeding members having a mountain-shaped cross section on the outer peripheral surface of the lower feeding roll 20b. A member 32 is provided in the axial direction, and each of the feeding rolls 20a and 20b is driven and rotated.

When the harvest A is supplied between the upper and lower feed rolls 20a and 20b, only the lower feed roll 20b is harvested A.
The crop A is vertically moved according to the supply amount of the rolls 20a and 20b, and the crop A is sandwiched between the feeding members 30 and 32 of the rolls 20a and 20b. From the cutting tool 18 to the cutting chamber 18, the crop A is cut in the up-cut state between the rotating cutting tool 6 and the fixed blade 34 fixed to the peripheral wall 10 at the upper end of the crop receiving port 12. Immediately after cutting, the cut material is discharged from the discharge port 14 through the chute 16 to the outside.

[Problems to be solved by the invention]

As described above, when the tooth-shaped feeding member 30 is attached to the outer peripheral surface of the upper feeding roll 20a, it has an advantage that it bites into the harvest A well and the feeding ability is improved, while the cutting chamber is cut. There is a problem that a part of the harvest A to be sent to 18 is easily carried around without being separated while being wound around the sending roll 20a.

When the scraper 36 is attached immediately before the upper feeding roll 20a in order to prevent the crop A from being rotated, since the feeding member 30 has a tooth shape, the tooth portion 3 of the feeding member 30 is formed.
There is a case where the crop A is clogged in the gap 38 between the scraper 36 and the scraper 36, and the upper feed roll 20a cannot be rotated.

Therefore, when the tooth-shaped feeding member 30 is attached to the outer peripheral surface of the upper feeding roll 20a, the scraper cannot be attached, and it is inevitable that the upper feeding roll 20a carries the harvest A. Become.

In view of such a problem, the present invention provides a harvester by changing the shape of the upper feed roll of the pair of feed rolls provided along the up-down direction on the front side of the harvest receiving port to a special shape. The purpose is to prevent the items from being carried around.

[Means for solving problems]

The present invention is a cylinder type harvester in which a pair of feed rolls are vertically arranged on the front side of a harvest receiving port provided on a peripheral wall of a blade case accommodating a blade, and an outer peripheral surface of an upper feed roll. A large number of feeding members formed by bending the bar material into a gentle V shape are arranged along the circumference, and the feeding members are attached so that the central bent portion faces the rotation direction. The feeding roll is attached so that it cannot move up and down, and a scraper is arranged in a space provided between the upper feeding roll and the peripheral wall of the blade case.

〔Example〕

1 to 5 show an embodiment of the present invention,
The same parts as those described in the above-mentioned "Prior Art" will be denoted by the same reference numerals.

A pair of feeding rolls 40 is provided on the front side of the harvest receiving port 12.
a and 40b are arranged vertically. On the outer peripheral surface of the upper feeding roll 40a, a large number of feeding members 42 formed by bending the central portion of the square bar into a gentle V shape are attached along the circumferential direction. The center bent portion 42a of the feeding member 42 is attached so as to face the rotation direction of the feeding roll 40a.

On the other hand, the lower feeding roll 40b has the same structure as the upper feeding roll 20a described in the section "Prior Art", and a plurality of tooth-shaped feeding members 44 are attached to the outer peripheral surface in the axial direction. Has been. A scraper 46 for preventing the crop A from being carried around is provided in the space between the upper feeding roll 40a and the peripheral wall 10 of the blade case 8.

When the harvest A is supplied between the upper and lower feed rolls 40a and 40b, the lower feed roll 40b is supplied according to the supply amount.
Only the vertical movement of the upper feed roll 40a and the feed member 44 of the lower feed roll 40b and the tooth-shaped feed member 44 of the lower feed roll 40a sandwich the harvest A into the cutting chamber 18. .

When the harvested material A is fed into the cutting chamber 18, the tooth-shaped feeding member 44 attached to the lower feeding roll 40b is used as the harvested material A.
Since the rod-shaped feeding member 42 attached to the upper feeding roll 40a only assists the feeding, the harvest A is less likely to wind around the upper feeding roll 40a. Since the attached harvest A is separated from the feed roll 40a by the scraper 46, the harvest A cannot be carried around.

Since the feeding member 42 attached to the upper feeding roll 40a is formed by bending a square bar into a gentle V shape, the feeding roll 40a has a shape close to a smooth roll. The feeding roll 40a rotates while the member 42 is always close to the scraper 46,
There is no large gap between the feeding member 42 and the feeding member 42. Therefore, the crop A is not clogged between the scraper 46 and the feeding member 42 attached to the feeding roll 40a, and the crop A wrapped around the outer periphery is separated by the scraper 46 so that the feeding roll 40a is smooth. Rotate to.

Further, the feeding member 42 in which the square bar is bent in a gentle V shape
Is attached to the feeding roll 40a so that the central bent portion 42a faces the direction of rotation, and as shown in FIG. 5, it is supplied in a nodular state between the upper and lower feeding rolls 40a and 40b. The harvested product A is moved to both ends of the feeding rolls 40a and 40b when being fed. Therefore, the harvest A is spread from the central portion in both directions perpendicular to the feeding direction and fed into the cutting chamber 18.

In addition, in this embodiment, since the tooth-shaped feeding member 44 is attached to the lower feeding roll 40b, there is an advantage that the feeding ability of the harvest A is enhanced, but the shape of the lower feeding roll 40b. May be anything as long as it can deliver the crop A.

[Effect of device]

In the present invention, since the shape of the upper feeding roll is close to a smooth roll, a scraper can be attached, and the crops wound around the upper feeding roll are separated by the scraper. The harvest is no longer carried around.

In addition, a bar material is gently V-shaped on the outer peripheral surface of the upper feeding roll.
Between the upper and lower feeding rolls, many feeding members bent in a letter shape are arranged along the circumferential direction, and the central bending part of this feeding member is oriented in the direction of rotation. The crops supplied in a nodule shape are moved to both ends of the feeding roll at the time of feeding, and are fed to the cutting chamber in an expanded state. Further, since the feeding member attached to the upper feeding roll is oriented in a direction inclined with respect to the axial direction of the feeding roll, timing adjustment is not necessary when mounting the upper and lower feeding rolls on the main body. .
