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 wandering straw east three-dimensional discharge device that drops and discharges waste straw in a vertical position with its stock pointing downward.

[Conventional technology]

Conventionally, as a three-dimensional discharging device for waste straw bundles configured like a snowflakes, there is one shown, for example, in Japanese Patent Application Laid-Open No. 57-74018. When viewed from the rear of the vehicle body, the endless rotation belt is provided by setting the rotation axis of the sprocket around which the endless chain is wound at an angle of about 45 degrees with respect to the horizontal.

[Problem that the invention seeks to solve]

In other words, by setting the posture of the endless chain as described above, the endless chain receives the bundled waste straw from the binding device in a sideways position at its front part, and also changes the posture of the bundled waste straw during conveyance. However, the structure is such that the bundled waste straw is discharged in a vertical position at the rear.

However, when the posture of the endless chain is set in this way, the binding is performed at an angle of approximately 45 degrees with respect to the conveying surface of the endless chain (a surface formed approximately parallel to the axis of the sprocket). This is because the bundled waste straw from the device is received and the bundled waste straw is similarly discharged in an attitude inclined approximately 45 degrees with respect to the conveying surface of the endless chain.
There is room for improvement, as conveyance defects may occur at the front and rear parts of the conveyance system, which consists of an endless chain.

In addition, when the endless rotating belt is made of an endless chain as in the above-mentioned example, the posture of the bundled waste straw is changed only by the weight of the bundled waste straw, so it is difficult to change the posture smoothly. There is also room for improvement.

The purpose of the present invention is to feed bundled waste straw without causing a lack of force throughout the conveying system consisting of an endless rotating belt, and to smoothly change the posture of the bundled waste straw in the conveyance system by rational modification. Another object of the present invention is to obtain a three-dimensional discharge device for waste straw bundles in which these operations are maintained well.

[Means for solving problems]

The feature of the present invention is that in a three-dimensional discharging device for discharging straw in an upright configuration, the rotational axis of the wheel on the upper side of conveyance, around which the endless rotating band is wound, is oriented substantially horizontally, and the rotation of the wheel on the lower side of conveyance is The respective axes are set approximately vertically, and the endless rotating belt is wound around these two wheels in a twisted state of approximately 90 degrees, and the conveying path side of this endless rotating belt is The guide member that determines the posture of the endless rotating band has a protruding guide portion for preventing lateral displacement of the endless rotating band, and the guide member is formed into a shape twisted approximately 90 degrees. And the effects are as follows.

[For production]

When the above characteristics are configured as shown in FIGS. 1, 2, and 4, the conveying surface of the endless rotating band (13) faces in the vertical direction at the front part of the conveying system, and Since the bundled waste straw (5) is directed in the left and right direction at the rear, the bundled waste straw (5) sent by this endless rotating belt (13) follows the conveying surface of the endless rotating belt (13) from the initial horizontal position to the vertical position. Therefore, it is difficult to cause conveyance defects, and furthermore, this endless rotating belt (1
Since the direction of change in attitude of the conveying surface during conveyance in step 3) coincides with the direction of change in attitude of the bundled waste straw (5), an endless rotation belt is used to change the attitude by the own weight of the bundled waste straw (5) as in the conventional method. (13) without having to take the trouble of adjusting the position of the clamping rail with respect to the band (13), just by arranging the clamping rail (14) in a fixed positional relationship with respect to the ruthless rotation band (13), the bundled waste straw ( 5) Posture changes can be made.

Moreover, even if the endless rotation band (13) is in a twisted state as described above, the guide parts (18a), (1
8a) prevents the endless rotation band (13) from shifting laterally.

〔Effect of the invention〕

Therefore, the bundled waste straw can be sent throughout the entire area of the conveying system consisting of the endless rotating belt without causing a lack of force, and the attitude of the bundled removing straw can be smoothly changed in the conveying system. Since the posture of the straw is stabilized, an east three-dimensional discharge device for removing straw in which these operations can be maintained satisfactorily has been obtained.

〔Example〕

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

As shown in Figures 3, 4, and 5, the threshing device (1)
An endless conveyor chain (2) is installed at the rear of the combine harvester body (2) equipped with a
3) and a locking and conveying device (4), and a binding device (A) for tying the waste straw from the discharge device into predetermined portions; The bundled waste straw (5) sent out from the bundling device (A) in a horizontal position is changed to a vertical position while being sent backward, and the bundled waste straw (5) is placed in a vertical position with the stock head facing downward. By dropping the bundled waste straw (5) against the ground (6)
) is installed in a three-dimensional discharge device (B) for discharging waste straw bundles 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 discharge 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 said wandering straw bundle three-dimensional discharge device (B) is a bundled straw bundle (
5), an endless rotation band (13) that sends the bundled waste straw (5), and a clamping rail (14) that presses the bundled waste straw (5) against the endless rotation band (13). It is made up of the following.

That is, as shown in FIGS. 1 and 2, the endless rotating belt (13) has a flat belt made of a flexible material and a locking protrusion (15).
), and is wound around a ring body (16) having a substantially horizontal rotation axis (X) on the upper side of the conveyor, and has a substantially vertical rotation axis (Y) on the lower side of the conveyor. It is arranged in a twisted state by approximately 90 degrees by being wound around the ring body (17).
