Description

[Detailed Description of the Invention] [Industrial Application Field] This invention provides a roll baler in which a package of grass that has been formed into a roll and packed in a chamber thereof is removed from the chamber by opening and rotating a rear chamber. The present invention relates to an improvement in a packed object discharging device in which a picker for rolling and guiding the packed object toward the rear of the machine body is provided on the lower surface side of the chamber when the packed object is discharged.

[Conventional technology]

Conventionally, the packaging discharge device in a roll baler was usually as shown in Fig. 1.
The lower surface side of chamber a formed by front chamber 1 and rear chamber 2 of the body of roll baler A supports the package that is ejected from chamber a when rear chamber 2 is rotated rearward. A kicker 3 consisting of a frame body 3a formed in a frame shape is installed so as to rotate downward about a fulcrum shaft 30 under a spring load.
In the normal state, it is held in a horizontal position as shown by the solid line in Fig. 1, and when the package is placed on the top surface, the weight of the package causes the fulcrum shaft 30 to be centered as shown by the chain line in Fig. 1. It is constructed by restricting it with a restriction spring 31 so that it is in a downwardly tilted and rotated state.

The package discharge device configured in this manner and installed on the body of roll baler A was developed to speedily discharge packages that have been formed and packed in chamber a. It is a means.

That is, when feed crops cut down in the field are being formed into bales and packaged by roll baler A, the package B that has been formed and packaged in chamber a. is the second
As shown in the figure, when the rear chamber 2 is rotated to open rearward and upward, the lower surface side of the chamber a is opened wide, allowing the product to fall through the opening and be discharged. However, in this state, when trying to turn the rear chamber 2 to close it, the rear chamber 2 gets stuck on the package B that has been ejected and placed on the ground as shown in Figure 4, and as shown in Figure 4. It is not possible to make it into a state. Therefore, with the rear chamber 2 shown in FIG. 2 previously rotated rearward and upward, the roll baler A is moved forward to the state shown in FIG. 5,
In this state, it is necessary to perform a process of closing and rotating the rear chamber 2 as shown in FIG.

However, if the body of the roll baler A is equipped with a package discharge device consisting of the above-mentioned picker 3, when the rear chamber 2 is opened and rotated, the package B to be discharged will be moved to the picker 3. The weight of the packaged object B causes it to tilt downward toward the rear, and it is guided by the upper surface of the carrier 3 and rolls backward, as shown in FIG. The state will be as follows. Therefore, in the above-mentioned process, by rotating the rear chamber 2 open, the state shown in FIG. 5 is achieved at once, and the work of discharging the packaged object B can be streamlined.

[Problem to be solved by the invention]

In the above-mentioned conventional packing discharge device using a picker, the fulcrum shaft 30 of the picker 3 is fixed to the body of the roll baler A below the front chamber 1. If you try to increase the angle of inclination when rotating downward so that package B can be easily discharged,
The position of the fulcrum shaft 30 of the kicker 3 has to be raised, resulting in a structure in which the position of the front chamber 1 is raised, resulting in a roll baler with a high center of gravity. This creates a risk of falling during work or driving, and requires a mechanism to transport the grass, rice straw, etc. to be picked up and packed up to a high position, which increases the weight of the machine. Close.

Furthermore, if the position of the fulcrum shaft 30 of the kicker 3 is lowered, the chamber a can be positioned lower and the body of the roll baler A can be made more stable. The angle of inclination becomes small when the package B is in this position, and the effect of rolling the discharged package B backward becomes uncertain, creating a problem in which the rear chamber 2 cannot be rotated to close.

The present invention has been made in order to solve these problems occurring in the conventional means, and it lowers the ground clearance of the chamber a, which is composed of a front chamber 1 and a rear chamber 2 closed thereto, and rolls out the roll. While the body of baler A has a structure with a low center of gravity, when the kicker 3 disposed below chamber a is tilted downward toward the rear, it is possible to reliably roll the discharged package B. The object of the present invention is to provide a new means for achieving a steep inclination angle.

[Means to solve the problem]

In the present invention, as a means to achieve this objective, the body of the roll baler,
A shelf frame-like rack capable of supporting a packaged object is installed on the lower surface side of the chamber formed by the front chamber and the rear chamber so that it is raised when the rear chamber is opened and lowered when the rear chamber is rotated to close. It is supported and installed on a bracket provided on the aircraft body so that it can be raised and lowered, and it is also supported on a fulcrum shaft provided on the bracket so that it can rotate up and down around the fulcrum shaft, so that it can be rotated upward by a spring load. This invention proposes a package discharge device for a roll baler that is biased.

〔Example〕

Next, embodiments will be described in detail with reference to the drawings. Note that the same reference numerals in the drawings as in the previous means are used for components having the same effect.

FIG. 8 is a schematic side view of the entire roll baler A in which the present invention can be carried out. The kit car to be installed, 20, connects the rear chamber 2 to the pivot shaft 21.
A hydraulic cylinder 5 is opened and rotated in the center, and numeral 5 indicates an elevating mechanism for elevating and lowering the kicker 3.

As shown in FIGS. 9 and 10, the kicker 3 attaches the front end of the frame 3a to a fulcrum shaft 3 on a bracket 4 attached to the body of the roll baler A.
The frame body 3a is pivotably supported vertically by 0.
A regulating spring 31 is stretched between the front and rear intermediate portions of the bracket 4 and a portion above the fulcrum shaft 30 of the bracket 4 to urge the frame body 3a to rotate upwardly about the fulcrum shaft 30. The support member 40 of the bracket 4 is attached to a portion of the upper surface of the body 3a near the front end when the frame body 3a is rotated upward to a horizontal position.
It is constructed by providing a stopper 32 that abuts against (FIG. 12) and prevents upward rotation from that position.

Then, the kicker 3 is attached to the bracket 4 mentioned above.
As shown in FIGS. 11 and 12, the end of the support member 40 that supports the It is integrally connected to and supported by an elevating member 51 provided to move up and down within a regulated range, and the elevating member 51 is rotatably connected to the lower end of a connecting rod 52. The upper end of the rod 52 is rotatably connected to the machine wall of the aft chamber 2 described above (9th
As a result, when the rear chamber 2 is rotated open by the extension operation of the hydraulic cylinder 20, the support member 40 that supports the bracket 4 is pulled up to the upper end position of the elongated hole 50, and the support member 40 of the kick car 3 is It constitutes an elevating mechanism 5 in which the position of the fulcrum shaft 30 moves upward.

The elevating member 51 of the elevating mechanism 5 is raised and lowered by a vertical sliding portion 510 integrally provided thereon slidingly contacting a vertical guide 53 fixed to the body of the roll baler A. According to regulations, the kicker 3 must be held in a predetermined position while being raised and lowered.

In addition, 6 is an extrusion member, which is formed into a flat plate shape and has a connecting portion 60 provided at its rear end, which is integrally connected to the front and rear intermediate portions of the frame 3a. By integrally connecting a connecting portion 61 provided on the lower surface side of the front and rear intermediate portions so as to hang downward to a portion near the front end of the frame 3a, a horizontal posture can be achieved as shown in FIG. The structure is such that the frame 3a of the kicker 3 is attached to the front half of the upper surface side of the frame 3a of the kicker 3 in a tilted upward position facing forward, and the frame 3a of the kicker 3 is attached to the upper half of the upper surface side of the frame 3a of the kicker 3. When pivoted downward about the fulcrum shaft 30, it comes into contact with the front side of the package B on the frame 3a and acts to push it backward. This extrusion member 6
may be omitted.

The embodiment device constructed in this manner operates as follows.

When the rear chamber 2 is opened by the operation of the hydraulic cylinder 20, the connecting rod 52 connected to the rear chamber 2 also moves in conjunction, and the elevating member 51 rises along the elongated hole 50.

The frame 3a of the kicker 3 is pulled upward by a regulating spring 31, and the stopper 32 is pulled upward by a support member 40.
It is held at a predetermined angle. Further, the connecting rod 52 and the lifting member 51 are connected to each other in a freely rotatable manner, and a change in the angle of the connecting rod 52 does not affect the mounting angle of the kicker 3. and,
The lifting member 51 and the supporting member 40 are a roll pin 54.
The angle of the elevating member 51 is determined by a guide 53 provided parallel to the elongated hole 50.

Therefore, the kicker 3 moves up in conjunction with the opening of the chamber while maintaining its normal angle.

Then, the weight of the package B to be supported causes the fulcrum shaft 30 to
It rotates downward around the center, thereby rolling off the supported package B.

After discharging the package B, rotate the rear chamber 2 to the closing side, and the connecting rod 52 will open.
When is pushed downward, the kicker 3 descends.

〔Effect of the invention〕

As explained above, the package discharge device for the roll baler according to the present invention supports the package B on the lower surface side of the chamber a formed by the front chamber 1 and the rear chamber 2 of the body of the roll baler A. A shelf frame-shaped kicker 3 that can be mounted is supported and installed on a bracket 4 provided on the fuselage so as to be movable up and down so as to rise when the rear chamber 2 is rotated to open and lowered when the rear chamber 2 is rotated to close. A fulcrum shaft 30 provided on the bracket 4
Since the support shaft 30 is supported so as to be able to freely rotate up and down around the fulcrum shaft 30, and is biased to rotate upward by a spring load, the kicker 3 is normally at a low position. , the roll baler A will move to a higher position only when opening the rear chamber 2 and discharging the packaged item B. Therefore, while the body of the roll baler A has a low ground clearance and a low center of gravity, The inclination angle of the kicker 3 during the work of discharging the object B can be set to a steep inclination that ensures the rolling of the packed object B.
