Description

Combine {COMBINE}

The present invention relates to a combine, and more specifically, to a combine with a large number of harvesters, such as an 8-row type.

Combines with a large number of harvesters, such as an 8-row type, have a large harvesting width (horizontal width) by the harvesting unit, exceeding the regulated width when driving on the road, so for example, when transporting by loading it on a transport vehicle. , there are problems such as not being able to drive on the road in that state.

Conventionally, in order to support the plurality of splitting holes of the reaping unit, the front and rear frames on both sides located at both ends in the reaping width direction among the plurality of anteroposterior frames extending in the front and rear direction of the body were removed, and the entire width in the reaping width direction was removed. There was a configuration in which the long cutting blades covering the blades were removed so that the horizontal width could be accommodated within a predetermined width (for example, see Patent Document 1).

<3>

In addition, conventionally, for example, in an 8-row combine, in order to support a plurality of splitting holes of the reaping unit, an anteroposterior frame on both sides located at both ends in the harvesting width direction among a plurality of anteroposterior frames extending in the front and rear direction of the body was used. There was a configuration so that the horizontal width could be accommodated within a predetermined width by switching to a separated state in which the long cutting blade spanning the entire width in the cutting width direction was removed along with the removal (for example, see Patent Document 1).

Japanese Patent Publication No. 2009-278902

The above-described conventional configuration is capable of harvesting 8 trillion worth of planted grain stems at once during reaping work, thereby increasing work efficiency. However, when driving on the road after the work is completed, the reaping blade, which is a large device, must be removed, or It is necessary to remove the front and rear frames at both ends in the width direction of the harvest. In addition, in addition to this, the erection device at both ends in the harvesting width direction, the support member for supporting the harvesting blade, and other small members had to be removed, which required laborious work. In addition, each removed device had to be stored separately from the combine body, making management of the removed devices cumbersome.

Therefore, there has been a demand for a combine that can increase the number of harvesting assistants and narrow the horizontal width when not working without requiring cumbersome and laborious work.

<3>

In addition, with the above-mentioned conventional configuration, under normal use conditions with many harvesting crews, 8 trillion worth of planted grain stems can be harvested at once, thereby improving harvesting work efficiency. However, for example, in the case of driving on the road, in the separated state in which a part of the reaping section is separated and the horizontal width is narrowed, not only the front and rear frames at both ends in the reaping width direction but also the reaping blades are removed, so it is switched to this separated state. After this, harvesting work could not be carried out.

Therefore, it has been desired to be able to perform harvesting work not only in a wide normal use state but also in a narrow separation state.

The characteristic configuration of the combine according to the present invention is:

A harvesting unit is provided at the front of the fuselage to harvest multiple sets of planted grain stems,

The reaping unit is equipped with a plurality of erecting devices corresponding to the reaping assistant, a cutting device for cutting the base of the planted grain stem, and a conveying device for conveying the harvested grain stem toward the rear of the machine,

Each of the standing devices has a standing action path that moves with the standing hook protruding, and a non-action return path that moves with the standing hook retracted,

Among the plurality of standing devices, the harvesting unit is capable of folding the standing device, the cutting device, and the conveying device around an axis provided at the boundary between adjacent standing devices in a state where the non-action return paths are close to each other. The point is that it is structured in a way.

According to the present invention, when it is necessary to narrow the vehicle width for driving on the road, etc., the horizontal width of the harvester can be narrowed by folding the harvester. Since the reaping unit is configured so that the erecting device, cutting device, and conveying device can be folded, when folding the reaping unit, each device or the large component parts that make up them can be removed individually, or the removed devices can be managed separately. cumbersome tasks such as these are unnecessary.

The axis for folding is installed at the boundary between adjacent standing devices with the non-action return paths close to each other, so when folded, the standing hooks of adjacent standing devices do not interfere, and the folding occurs smoothly. can do.

Therefore, according to the present invention, it has become possible to narrow the horizontal width during non-working hours without requiring cumbersome and labor-intensive work while increasing the number of harvesting assistants.

In the present invention, it is suitable if each of the standing device, the cutting device, and the conveying device are configured to be integrally foldable around the axis provided at the boundary.

According to this configuration, each of the standing device, the cutting device, and the conveying device can be folded integrally, so it is possible to perform the folding operation at once without the need to fold each device individually, which improves work efficiency. This can further reduce the effort of work.

In the present invention, the conveyance device includes a conveyance portion on the folded side corresponding to the reaping portion divider on the folded side of the reaping portion, and another conveyance portion corresponding to the other reaping portion divider in the reaping portion. Equipped with

It is suitable if the conveyance section on the folding side is configured to independently convey the harvested grain stem to the position where it is conveyed from the other conveyance section.

According to this configuration, in the reaping operation state, the reaping grain stems harvested from the reaping unit divider on the folding side are transported in a state independent of the other transport units by the transport unit on the folding side, and are transported by the other transport units. It is conveyed to the location and joins the reaping grain stems harvested from other reaping section divisions. That is, in the reaping operation state, the planted grain stems of all the reaping target groups in the reaping unit can be conveyed backward while joining them during conveyance.

In addition, since the conveyance unit on the folding side can be conveyed in a state independent of other conveyance units, when the reaping section partition on the folding side is folded for driving on the road, etc., it is in an electrically connected state with the other conveyance units. There is no need for cumbersome tasks such as deactivating .

In the present invention, in each of the conveyance section on the folding side and the other conveyance section, there is one set or plurality of grain stem scraping devices consisting of a drive side packer that is rotationally driven and a driven side packer that engages and follows the drive side packer. A set is provided,

It is suitable if the said harvesting part is separated from the boundary between the said grain stem scraping devices and is comprised so that folding is possible.

According to this configuration, the harvested grain stem is raked toward the rear and conveyed by a grain raking device consisting of a drive side packer that is rotationally driven and a driven side packer that engages and follows the drive side packer. Since this packer type grain raking device only needs to transmit power to the drive side packer, the transmission structure can be simplified compared to a configuration in which a pair of packers are individually driven.

The conveyance unit on the folding side and the other conveyance unit are each equipped with one set or multiple sets of grain stem scraping devices, and the reaping unit divided body on the folding side and the other reaping unit divided unit are the conveying unit on the folding side and the other conveying unit, respectively. Since it is separated at the boundary between the grain stem scraping devices, the engagement state of the grain stem scraping devices does not change due to the folding operation. Therefore, the folding operation of the harvesting unit can be performed satisfactorily while keeping the transmission structure simple.

In the present invention, the transport device is configured to merge multiple sets of reaped grain stems at the merging point while transporting them to the rear of the body, and further transports the reaped grain stems harvested from the reaping section divider on the folded side to the merging point. Equipped with a conveying unit for conveying,

It is suitable if the merging conveyance part is divided into a merging conveyance body on the folding side provided in the folding side conveyance section and another merging conveyance body provided in the other conveyance section.

According to this configuration, multiple sets of reaped grain culms are joined at the confluence point and conveyed toward the rear of the aircraft, but the reaped grain stems harvested from the reaping unit divider on the folded side are transported to the convergence point by the convergence conveyance unit.

When the reaping unit division on the folding side is folded, the merging conveyor is separated into a merging conveyor on the folding side and another merging conveyor, and the merging conveyor on the folding side is integrated with the reaping portion division on the folding side. moves, and the other merging carrier remains on the side of the other reaping section division body.

Therefore, during reaping work, the harvested grain stem can be favorably conveyed by the merging conveyance unit, and when the reaping portion is folded, it can be folded favorably without being hindered by the merging conveyance portion.

In the present invention, the cutting device is provided with a cutting portion on the folding side corresponding to the reaping portion division body on the folding side of the harvesting portion, and another cutting portion corresponding to another harvesting portion dividing body in the harvesting portion. do,

It is suitable if the harvesting unit is separately provided with a power transmission part on the folding side that transmits power to the cutting part on the folding side and another power transmission part that transmits power to the other cutting part.

According to this configuration, when the reaping portion partition on the folding side is folded, the cutting device is separated into a cutting portion on the folding side and another cutting portion, and in addition, the power transmission portion is provided separately, so the cutting portion on the folding side and the power transmitting portion on the folding side are provided separately. The transmission part moves integrally with the reaping part division body on the folding side, and the other cutting part and the other power transmission part remain on the other reaping part division side.

Therefore, during reaping work, the entire cutting device can be used to properly cut and reap the harvested grain stalks in the entire harvesting target group, and when folding the reaping portion, it can be folded as is without removing the cutting device.

In the present invention, it is suitable if power is transmitted from the same transmission shaft to each of the power transmission unit on the folded side and the other power transmission unit.

According to this configuration, power is transmitted to each of the power transmission unit on the folding side and the other power transmission unit from the same transmission shaft, so the cutting unit on the folding side and the other cutting unit are driven in a synchronous or approximately synchronous state. As a result, there is no fear of misalignment of the driving timing between the cutting portion on the folding side and the other cutting portion, and the cutting device can be operated smoothly.

In the present invention, the operation unit is provided in a state where the harvesting unit is located at the rear of the body and on one side in the horizontal width direction of the body,

The harvesting unit includes a transverse input shaft located at the lower side of the rear portion through which power is input, a transverse standing drive shaft spanning between upper parts of the plurality of standing devices, and an end located on the opposite side of the transverse direction with respect to the operating unit. and a vertical relay shaft that transmits power from the input shaft to the standing drive shaft,

The input shaft and the standing drive shaft each have a rolling part on the folding side corresponding to the reaping part divider on the folded side of the reaping unit, and another driving part corresponding to the other reaping part dividing body in the reaping part. It is suitable if it has a power connection part that can connect and separate the electric part on the folding side and the other electric part.

According to this configuration, during the reaping operation, the power for the reaping unit is transmitted to the horizontal input shaft, and is transmitted from the input shaft to the standing drive shaft located at the upper part of the standing device through the vertical relay shaft. Since the vertical relay shaft is located at the end on the opposite side in the horizontal direction to the operating unit, the relay shaft does not interfere with the operating unit even when, for example, the operating unit is provided with a cabin and protrudes toward the harvesting unit side. Power can be transmitted to the standing drive shaft.

When the reaping unit is folded, the input shaft and the standing drive shaft are separated into a power connection part on the folding side and another rotating part, respectively, and the rotating part on the folding side is integrated with the reaping section divider on the folding side. It moves, and another transmission part remains on the other reaping part divider side.

Therefore, during reaping work, power can be appropriately transmitted to a plurality of standing devices, and when folding the harvesting unit, the input shaft and standing drive shaft can be folded satisfactorily without being hindered by them, even without removing them.

In the present invention, a power transmission shaft in the forward and backward directions is provided to transmit power from the aircraft side to the input shaft,

The conveying device is provided with a conveying portion on the folding side corresponding to the reaping portion division on the folding side of the reaping portion, and another conveying portion corresponding to the other reaping portion dividing portion in the reaping portion,

Power from the power transmission shaft is transmitted to the conveyance unit on the folded side via the input shaft,

It is suitable if the power from the power transmission shaft is directly transmitted to the other conveyance unit.

According to this configuration, power from the aircraft side is transmitted through the power transmission shaft, and power is transmitted directly to other conveyance parts from the power transmission shaft. On the other hand, the power transmitted to the power transmission shaft is transmitted to the conveyance part on the folding side via the input shaft.

Therefore, by transmitting power to the conveyance unit on the folding side via an input shaft that is separated along the way, work such as removing the conveyance unit is unnecessary, and the folding operation of the harvesting unit can be performed smoothly. On the other hand, the other conveyance unit can maintain an appropriate rolling state regardless of the folding operation.

In the present invention, the operation unit is provided in a state where the harvesting unit is located on the rear side of the body and on one side in the horizontal width direction of the body,

The conveying device is provided with a one-side guide portion that guides the harvested grain stem in a tank located on one side of the body width direction among the plurality of tanks toward the rear of the body to the other side of the body width direction,

The one-side guide part is provided with a front-side endless rotating body located on the front side of the aircraft, and a rear-side endless rotating body located on the rear side of the aircraft,

The front side endless rotating body and the rear side endless rotating body have a conveyance path for conveying the harvested grain stem on the other side of the body transverse direction, and a non-conveyance path is set on one side of the body transverse direction, and the ratio It is suitable if the conveyance path is arranged so as to be concave toward the other side of the body in the width direction.

According to this configuration, one guide portion of the conveying device guides the harvesting grain stem located on one side in the width direction of the body toward the rear to the other side in the width direction of the body. In other words, the conveying device feeds the threshing device on the rear side of the aircraft while combining multiple sets of planted grain culms harvested in the reaping unit, but the planted grain culms located on one side in the horizontal width direction of the aircraft are located on the central side of the aircraft, that is, along the horizontal plane of the aircraft. It is necessary to guide it in an oblique direction toward the other side of the width direction.

Since the driving part is located on the rear side of this one-side guide part, if the one-side guiding part is composed of one endless rotating body, there is a risk that the driving part may interfere with the other end in the width direction of the body. In particular, when tightened in large numbers, the overlapping width of the reaping section and the operating section along the horizontal width direction of the body tends to increase.

Therefore, a state in which a front-side endless rotary body and a rear-side endless rotary body are provided as one-side guide portion, and the non-conveyance path set on one side of the body transverse direction of both rotors is recessed toward the other side of the body width direction. It is arranged so that By configuring in this way, it becomes possible to convey the reaping grain stem while avoiding interference with the other end in the width direction of the body of the operating unit. As a result, even if the overlapping width of the reaping section and the operating section along the body width direction is increased, it becomes easy to avoid interference between the one-side guide section and the operating section.

The characteristic configuration of the combine according to the present invention is:

A harvesting unit is provided at the front of the fuselage to harvest multiple sets of planted grain stems,

The reaping unit is provided with a plurality of erecting devices corresponding to the reaping assistant, a cutting device for cutting the base of the planted grain stem, and a conveying device for conveying the harvested grain stem toward the rear of the machine, and is positioned halfway in the harvesting width direction. It is divided into one side reaping part split body and the other side reaping part split part,

A normal use state in which the one side reaping part divider is arranged in series in the harvesting width direction with respect to the other side reaping part divider, and the front face of the one side reaping part divider and the front face of the other side reaping part divider face each other. From the folded state to the overlapping state, it is supported rotatably around a rotation axis in the vertical direction corresponding to the intermediate position.

According to the present invention, the reaping part is divided into one reaping part split body and the other reaping part split body at a mid-position in the reaping width direction. And, when carrying out a harvesting operation, a good harvesting operation can be performed by putting the one-side reaping part division body and the said other side harvesting part division body in a normal use state in which they are arranged in series in the harvesting width direction. When it is necessary to narrow the vehicle width for driving on the road, etc., the one-side harvesting section divider is rotated around the vertical rotation axis so that the front face of the one-side harvesting section divider faces the front face of the other side harvesting section divider. By switching from the folded state to the overlapping state, the horizontal width can be narrowed.

When folding the reaping unit in this way, it can be handled by rotating the one-side reaping unit division around the rotation axis in the vertical direction, so large components, etc. can be removed individually, or multiple removed devices can be managed separately, etc. There is no need for cumbersome work.

According to this configuration, each upper end of the plurality of standing devices is connected to an upper horizontal frame, and each lower end is connected to a front-to-back frame extending along the front-back direction of the body. And, each of the both ends in the harvesting width direction of the lower side horizontal frame and each of the both ends in the harvesting width direction of the upper horizontal frame are connected by a vertical frame. An anteroposterior frame located at both ends in the harvesting width direction, a vertical frame, and a standing device located at both ends in the harvesting width direction are arranged in a substantially triangular shape when viewed from the side of the body, and are connected.

In each of the one-side reaping section divided body and the other side harvesting section divided body, the front-back direction frame, the up-down direction frame, and the standing device are connected in a substantially triangular shape when viewed from the side of the body, forming a strong frame structure.

Therefore, since each of the one-side reaping section divider and the other side reaping section divider is provided with a strong frame structure, the reaping section can maintain its posture in a stable state in either the normal working state or the folded state, and can be used for harvesting work or transportation. Work, etc. can be performed satisfactorily.

In the present invention,

The connecting frame is installed in a state extending in the vertical direction across the upper horizontal frame and the front-to-back frame, so that both the upper and lower sides are stably supported. With such a connecting frame, the one-side harvesting unit divided body can be rotated in a stable state, and the posture change operation can be performed satisfactorily.

<3>

The characteristic configuration of the combine according to the present invention is:

A harvesting unit is provided at the front of the fuselage to harvest multiple sets of planted grain stems,
