Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a method for sliding a grain removal cylinder extending downwardly at the lower end of a bagging hopper along the axial direction of the cylinder. A movable boot is fitted, and the boot can be moved up and down between a lowered position in which the boot is inserted into the upper opening of the bag held by the bag support rod, and a raised position in which it is pulled out of the upper opening of the bag. The present invention relates to a boot operation structure for a grain bagging device that is provided in a position-switchable manner.

[Prior art and problems to be solved by the invention]

Conventionally, in the above-mentioned grain bagging apparatus, the position of the boot has been changed manually, and the bagging operation requires a lot of effort.

[Means to solve the problem]

The characteristic configuration of the present invention is that, in the above-mentioned boot operation structure of the grain bagging device, [B] As a drive source for raising and lowering the boot,
In addition to using an endless rotating band that is rotated,
An operating mechanism is provided for converting and transmitting the operation of the endless rotation band into an operation for switching the boot's vertical position.

[B] The endless rotating band is configured to be able to be switched between forward and reverse directions, and includes an operating member that transmits its rotational operation to the operating mechanism.

[C] The operating mechanism includes an operated member that is configured to contact the operating member and freely switch its posture between two positions in the forward and reverse directions as the endless rotation band rotates forward and reverse. , and a linking means for switching the vertical position of the boot in accordance with the posture switching operation of the operated member in the forward and reverse directions.

[d] The operated member is configured to be able to freely switch its posture between two positions in the forward and reverse directions in the contact action range that enters the rotation locus of the endless rotation band, and It is configured to be movable to a retraction range that is outside the locus that is the action range.

[E] The linking means moves the boot upward or downward as the operated member moves in one direction within the contact action range,
and includes an operation transmission member that moves the boot in the opposite direction as the boot moves in the other direction, and allows the operated member to move out of the trajectory by contacting the operating member. ,
The operating member is further provided with a restoring means that elastically urges the operated member to enter the trajectory when the operating member is released from contact with the operating member.

The present invention is provided with the configurations described in [A] to [E] above. The functions and effects thereof are as follows.

[Effect]

Even without providing separate drive mechanisms for raising and lowering the boot, simply by switching the drive rotation direction of the endless rotation band, the endless rotation band is rotated in one direction and the rotation force is used to drive the boot. The boot can be lowered to the use position, or rotated in the other direction, and the rotational force can be used to raise the boot to the storage position.

〔Effect of the invention〕

The position of the boot can be changed without using manual force using the endless rotating belt as the driving force, making bagging work easier.
