Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a straw harvester that is equipped with a selection device that selects between layers while hanging and transporting straw after harvesting.

[Conventional technology]

Conventionally, in this type of rush harvester, the bedside portion of the rush that is suspended and sent by a clamping and conveying device is rotated with a multi-stage locking claw that rotates the bedside part of the rush in a horizontal direction perpendicular to the conveying direction. The system adopted a structure in which the waste was picked out by combing it with a chain, and the locking claws caught it from below, scooped it up, laid it down on its side, and placed it on the collection deck. -60043).

[Problem to be solved by the invention]

In this case, the feature is that only the rotary chain with a locking pawl has the function of placing the rush grass in a sideways position while selecting the space between the layers. Since the grass is laid on its side so as to be hooked and forcibly scooped up, the locking claws do not come into contact with all the grass being conveyed evenly, resulting in some remaining grass being removed, resulting in insufficient removal between equal layers. .

An object of the present invention is to provide a selection device that can reduce the amount left unpicked between layers by employing an appropriate mechanism.

[Means to solve the problem]

The characteristic structure of the present invention is that: (1) a general feeding device for transporting the cut straw grass by suspending it and holding it there is provided; A selection work beater is provided which selects between layers by applying a "slapping and flipping" action with a larger number of movable claws, and lifts the root side of the rush to a predetermined height. That's right.

[For production]

For example, if a rotary type beater (6) for selection work is used as shown in Fig. 2, a rotary moving claw (6b) is used.
) can be applied intermittently and at short intervals to the base side of the rush, thereby giving it a "swatting" effect on the rush. The rush is then subjected to vibrations, and if there are any interlayers, they are sieved off and separated. Furthermore, since it imparts a "swatting" action, it is possible to untangle the strawberries even if they are entangled with each other, making it even easier to remove the layers.

Moreover, in addition to applying the "pounding" action, by turning the direction of the "pounding" diagonally upward and applying a force to lift the rush, it is possible to lift it to a predetermined height for handing over to the next process. At the same time, it has the effect of separating layers and loosening the entanglement of rushes.

〔Effect of the invention〕

In contrast to the conventional method that applies a relatively static selection action that supports and combs the rushes, we have adopted a method that adds a dynamic selection action by "pounding and flipping up".
By applying a forced vibration force to the grass that is suspended and clamped, an indirect selection action can be applied to the grass that the movable claws do not directly act on, making it possible to uniformly remove the layers. Moreover, when such a mechanical sorting device is not used, the worker holds one end of the straw bundle and shakes the hanging straw grass from side to side to apply vibrations to remove the interlayers. By giving this, it is possible to follow the operator's method of selecting between layers.

In this case, the rotary drive shaft (6A) is tilted to apply a bouncing action to the grass.
As b), since a material with elastic force is used, the material absorbs the impact force acting on the grass, thereby alleviating damage to the grass, and also doubles the force of springing up due to the elastic repulsive force. There is also.

As shown in Figures 1 and 3, a guide wall (13) is provided from the outside of the rotary mold (6b) toward the lateral side of the fuselage, and this guide wall (13) can be tilted upward and backward. In addition, the posture is set so that the end of the fuselage is positioned closer to the front of the fuselage. Therefore, since the rush that is thrown up by the beater (6) blows up along the guide wall (13), the guide wall (13) prevents the grass from expanding and the guide wall (I3 ) can be sequentially lifted onto the collection deck (10) starting from the top.

As shown in Fig. 2, a pair of vertically rotating conveyor belts (17) with large protrusions are installed on the upper surface of the collection deck (10) near the upper end of this guide wall (13) along the lateral direction of the machine.
