Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention provides a thresher that is mounted on the front side of a traveling machine base, and an engine covered with a cover on the rear side. The present invention relates to an attachment device for a self-propelled, self-removing grain bag holder, which is provided with a control section on the upper surface of the cover and includes a bag holder that supports a grain bag that receives grain from a threshing machine.

(b) Prior art In the above-mentioned self-propelled self-ejection, there is a conventional technology that changes the attitude between an upright attitude in which the bag holder is stored in the body side and a horizontal attitude in which the grain bag is supported. For example, the configuration shown in Japanese Utility Model Application Publication No. 52-83961 is generally known, but the bag holder with the configuration shown in the same publication attempts to change its posture from an upright position for storage to a horizontal position. When the worker's position is unexpectedly changed, the worker's leg becomes horizontal all at once, which is dangerous, and the support part that keeps the worker in the horizontal position receives a strong impact. This had drawbacks such as damage to the parts.

(c) Problems to be Solved by the Invention Accordingly, the present invention has a bag holder positioned on the rear side of the cover, and is placed in an upright position to be stored along with the cover. The distance from the operator's position to the control unit is shortened to make it easier to operate the steering while driving, and the above-mentioned drawbacks of the conventional system are resolved to ensure worker safety. This was done to prevent the support part from being damaged.

(d) Means for Solving the Problems Therefore, in order to achieve the above object, the present invention includes a threshing machine mounted on the front side of the traveling machine base, and an engine covered with a cover on the rear side. The self-propelled self-ejecting device is provided with a control section on the upper surface of the cover, and is equipped with a bag holder for supporting a grain bag receiving grains from a threshing machine, and the bag holder is attached to the cover. The bag holder is configured to be rotatable on the rear side about a left-right axis and can be changed into an upright position in which the grain bag is stored along the cover side and a horizontal position in which the grain bag is supported. After fixing a contact piece to be connected to the traveling machine base side near the axis rod on the base side and temporarily stopping the bag holder in the tilted position while changing the bag holder from the upright position to the horizontal position, By undoing the connection, the robot changed from a tilted position to a horizontal position, creating a configuration that allows the position to be changed in two stages.

(E) Function With this configuration, when the self-propelled self-escape is run, the bag holder provided on the rear side of the cover can be placed in an upright position and aligned with the cover, and the control section can be accessed from the operator's position. The distance between the bag holder and the bag holder has been shortened, making steering operations easier. When the bag holder is released and placed in a horizontal position, the bag holder falls down from the standing position and becomes horizontal, but in the middle of the process, the contact piece joins to the traveling machine base, and it stops once and becomes a tilted position. When solved, the tilted position changes to a horizontal position, and the position is changed in two stages to support the grain bag.

(f) Examples The present invention will be described in detail below based on the drawings of examples.

A threshing machine B is mounted on a loading platform on the front side of a traveling machine platform 3 supported by both crawlers 2, 2, so that it can be loaded and unloaded freely, and an engine and other devices are installed on the upper part of the rear side, and a cover 4 is covered. A handle 5 is fixed on the rear side from the top of the cover 4, and a group of operating levers 6 are arranged on the top surface of the cover 4 on the front side to form a control section A. A flat grain platform 7 on which a grain bag is placed is installed, and an auxiliary frame 8 extending outward from the side of the grain platform 7 is arranged in series.

A support frame 13 having a rectangular cross section is fixed horizontally to the rear of the traveling machine base 3 on the rear side of the grain platform 7 and the cover 4 below the handle 5 which is the rearmost part of the machine body. The bases of both brackets 14, 14 extending diagonally rearward and downward are fixed to both ends of the support frame 13 within the width of the support frame 13.
Both ends of a round bar shaft rod 15 are fixed to the lower ends of 4 and 14, and the shaft rod 15 is installed in the left-right direction.
A support pipe 16 having a length of about half of 5 is slidably fitted into the support pipe 16, and intermediate parts of arms 17, 17 extending in the front and back direction are fixed to both ends of the support pipe 16. 17, 17, and the supporting plate 18 is connected to the front part of a wide bowl-shaped bag holder C that can support two grain bags, and the bag holder C is connected to the shaft 15 on the rear side of the cover 4. The arms 17, 17 on the side of the bag holder C in the vicinity of the shaft 15 are provided with the front parts of the arms 17, 17 on the side of the traveling machine stand 3 when the bag holder C is in a horizontal state. Contact pieces 19, 19 whose upper surfaces are joined to the lower surface of the support frame 13 are bent to the right, respectively, so that the side surface of the right contact piece 19 is attached to the lower edge of the right bracket 14, as shown in FIG. In the joined state, the bag holder C is provided so as to be supported diagonally in an inclined position, and when the support pipe 16 is slid onto the shaft rod 15 and moved to the right side, the bag holder C is attached to the wheels of both crawlers 2, 2. When the support pipe 16 is positioned within the width and the support pipe 16 is moved to the left side with respect to the shaft rod 15, the left side of the bag holder C protrudes from the crawler 2 to the outside of the machine body.

Further, on both sides of the rear part of the cover 4, there are pipes 20, 2 for supporting the cover 4, the handle 5, etc.
0 is set upright, and a holder 22 that is pulled downward by a tension spring 21 is provided as a support 23 on the outer side of the upper part of the left pipe 20, and when the bag holder C is placed in an upright position to accommodate the bag holder C, the bag holder A holder 22 can be engaged with a flange 24 formed around C.

With this configuration, during threshing work,
As shown in FIGS. 4 and 6, when the support pipe 16 is moved to the left side with respect to the shaft rod 15, both arms 17,
The upper surfaces of the contact pieces 19, 19 of 17 are joined to the lower surface of the support frame 13, and the bag holder C is supported in a horizontal position to support the grain bag, with the left side protruding outward from the crawler 2. Above the bag holder C, the lower portions of the two grain bags are suspended by both grain receiving rods 12, 12 and are exposed to the threshed grain outlet ports 10, 10, respectively.

When running the machine or using it as a transport vehicle, lift the bag holder C from the state shown in Figures 4 and 6 above to the standing position, and then press the right abutment piece. 19 is the right bracket 1

5, and pull the holder 22 from above to engage the flange 24 on the upper side of the bag holder C in the upright position.
As shown in the figure, the bag holder C is now stored in an upright position on the rear side of the cover 4 and within the width of the left and right vehicles, thereby shortening the distance from the operator's position to the control section A. This makes steering operations easier and maneuverability easier.

To change the bag holder C from an upright position to a horizontal position, release the holder 22 that is engaged with the flange 24 and turn the bag holder C into a horizontal position. As shown in FIG. 1, as shown in FIG. When the bag holder C is moved to the left side from this inclined position, the side surface of the contact piece 19 comes off from the lower edge of the bracket 14, and the connection is broken, and the bag holder C is moved to the left side. The grain bag is supported from the tilted position to the horizontal position as described above.

In this way, when the bag holder C changes its posture from the standing posture for storage to the horizontal posture for supporting the lower part of the grain bag, the bag holder C has two stages: one from the standing posture to the tilted posture, and one from the tilted posture to the horizontal posture. The posture is changed by , and the posture is not changed from a standing posture to a horizontal posture all at once.

(G) Effects of the Invention As described in detail above, the present invention includes a thresher mounted on the front side of a traveling machine base, an engine covered with a cover on the rear side, and a top surface of the cover. is a self-propelled self-ejecting machine equipped with a control section and a bag holder for supporting a grain bag receiving grains from a threshing machine, and the bag holder is mounted on the rear side of the cover with a left-right axis. The grain bag is configured to be rotatable about the rod as an axis and can be changed into an upright position in which the bag is stored along the cover side and a horizontal position in which the grain bag is supported, and a portion near the shaft rod on the bag holder side. Then, a contact piece to be joined to the traveling machine base side is fixed, and while the bag holder is being changed from the upright position to the horizontal position, the bag holder is temporarily stopped in the tilted position, and then the joint is released and the bag holder is changed from the tilted position to the horizontal position. In posture, 2
Since the structure allows the position to be changed in stages, the bag holder located on the rear side of the cover can be placed in an upright position for storage along with the cover, from the operator's position to the control section provided on the top of the cover. When changing from an upright position to a horizontal position, or when changing the position unexpectedly In addition, the bag holder's posture is changed through one stage from a standing position to a tilted position and two stages from a tilted position to a horizontal position, and the bag holder does not change from a standing position to a horizontal position all at once. This ensures safety by preventing workers from inadvertently incurring bruises or lacerations on their legs due to the bag holder changing its position all at once.At the same time, it also prevents impact to the support part of the bag holder which changes its position to a horizontal position. In addition, since the contact piece that temporarily stops the bag holder in an inclined position is provided near the shaft lever, the bag holder can be completely filled with water on the bag holder. There is an effect that the abutment piece does not interfere with taking out the grain bag, regardless of whether the grain bag is taken out backward or to the left and right sides.
