Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is provided with an endless rotating band that receives and sends bundled waste straw sent out from a binding device in a horizontal position, and the tied waste straw sent by the endless rotating band is This invention relates to a three-dimensional waste straw bundle discharge device that drops and discharges waste straw in a vertical position with its base facing downward.

[Conventional technology]

Conventionally, as a three-dimensional discharging device for waste straw bundles configured like a snowflake, there is one disclosed in, for example, Japanese Patent Application Laid-Open No. 57-74018. The bundled wandering straw that forms a band and is transported by this endless chain changes its posture to a vertical position before the end of transport, and reaches the vicinity of the sprocket located on the lower side of transport among the two sprockets. The structure is such that the conveyance is completed at the point where the material is dropped and released.

[Problem that the invention seeks to solve]

However, the endless rotating belt that conveys the bundled waste straw in this way is usually formed with a locking protrusion that bites into the bundled waste straw, and the endless rotating belt with the protrusion formed in this way When the bundled waste straw is conveyed, the protrusions dig deeply into the waste straw, and even when the end of the conveyance is reached, the stray straw may not be released smoothly, so there is room for improvement.

The purpose of the present invention is to create a structure as simple as possible for smoothly discharging bundled wandering straw that has reached the end of conveyance using an endless rotating belt.
The object of the present invention is to obtain a three-dimensional discharge device for wandering straw bundles.

[Means for solving problems]

A feature of the present invention is that in a three-dimensional discharge device for discharging straw bundles having a snow lift configuration, the endless rotation band is wound approximately coaxially with a wheel on the lower side of conveyance around which the endless rotating band is wound in an arc shape with respect to the wheel. The rotary member is provided with a diameter that is approximately the same as or larger than the outer circumferential edge of the endless rotating band, and its functions and effects are as follows.

[For production]

If the above characteristics are configured as shown in FIGS. 1 and 2, for example, the bundled waste straw (5) that has reached the side of the wheel body (17) on the lower side of the conveyor is moved between the rotating members (23) and (23). Due to the contact with the endless rotation band (13), the protrusion (15) is pushed out in a direction away from the protrusion (15).

〔Effect of the invention〕

Therefore, by a relatively simple modification of installing a rotating member on the wheel, the bundled waste straw that has reached the end of the conveyance system can be reliably separated from the protrusion, even if it is deeply wedged into the protrusion. Therefore, a three-dimensional waste straw bundle discharge device was obtained in which the bundled waste straw is smoothly released.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

'As shown in Fig. 2, Fig. 2, and Fig. 4, the threshing device (1
) is equipped with a discharging device consisting of an endless conveying chain (3) and a locking conveying device (4) to send out waste straw from the threshing device (1). A bundling device (A) is provided for bundling the wandering straw from the discharging device in predetermined quantities, and furthermore, a bundling waste straw (5) that is sent out from the bundling device (A) in a sideways attitude to the rear end of the vehicle body (2) is provided. By changing the posture to a vertical position while sending it backwards, and dropping the bundled waste straw (5) in a vertical position with the plant head facing downward, the bundled straw (5) is dropped against the ground (6).
A three-dimensional discharge device (B) for discharging waste straw bundles is installed to discharge the waste straw bundle 5) in a standing position as shown in FIG.

The binding device (A) has a needle (7) on the top, a transmission case (8) that drives the needle (7), and a needle (7).
It is equipped with a string reel (9) etc. for supplying a string for tying, and a knotting section (10) at the bottom that forms a knot in the string fed in by a needle (7), and a discharge section that releases the tied straw bundle. The waste straw sent from the discharging device is bundled on the upper surface of a guiding table (12) that is tilted slightly backward, and is placed in a horizontal position along this table (12). released in

Moreover, the waste straw bundle three-dimensional discharge device (B)
5), an endless rotating band (13) that sends the bundled waste straw (5), and a clamping rail (14) that presses the bundled waste straw (5) against the endless rotating band (13). It is made up of the following.

That is, as shown in FIGS. 1 and 5, the endless rotating belt (13) has a flat belt made of a flexible material with a locking protrusion (15).
), and is wound around a transponder (16) having an approximately horizontal rotation axis (X) on the upper side of the conveyor, and has an approximately vertical axis of rotation (Y) on the lower side of the conveyor. It is arranged in a state where it is twisted approximately 90 degrees by being wound around the ring body (17).

Furthermore, the endless rotating belt (13) has its conveyance start surface facing downward, and the endless rotating belt (13) is twisted as described above.
The guide material (18) that determines the attitude on the conveyance route side of 3) is also twisted approximately 90 degrees, and this guide material (18)
) is provided with two protruding guide portions (18a), (18a) at positions that sandwich the endless rotating band (13) from the width direction in order to prevent the endless rotating band (13) from shifting laterally. There is.

Further, the holding rail (14) is located below the endless rotating band (13), and its front end side is supported with respect to the vehicle body (2) via a biasing spring (19). This rear end side is supported via a biasing spring (21) to a stay (20) extending from the vehicle body (2).

As shown in Fig. 2, a protrusion (22) is attached to the rear end of the clamping rail (14) so as to face the endless rotation band (13), and the bundled waste straw (5) is conveyed. This protrusion (22
), the bundled waste straw (5) is twisted around the culm direction, and as a result, the stock side expands, and the terminal end (14a) of the clamping rail (14) is connected to the rear wheel body (17). ), and the inertia force directed toward the rear immediately after the end of conveyance by the endless rotation belt (13) is suppressed by contact with the end portion (14a) formed in a curved manner in this way. , the bundled waste straw (5) is allowed to fall vertically downward.

Furthermore, when the conveyance by the endless rotating band (13) is completed, the rear wheel body Disk-shaped rotating members (23), (23) having a larger diameter than the wheel body (17) are attached to (17).

In addition, the front wheel body (16) around which the endless rotation band (13) is wound
is supported by the frame (24), and the power from the transmission case (8) constituting the binding device (^) is transmitted via the bevel case (25) 1 and the chain transmission mechanism (26), and The rear wheel body (17) is the frame (24)
It is disposed in a state where it is biased in the tension direction by a tension spring (27).
