Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a peeling device for stripping bracts from tufts of corn.

In the conventional peeling apparatus, a plurality of peeling rolls extending in the longitudinal direction of the apparatus are arranged in the lateral direction of the apparatus, and a conveying section for conveying crops rearward extends in the lateral direction of the apparatus and is arranged in the longitudinal direction. Some are configured with a plurality of feed members in a state. As a power transmission mechanism for transmitting power to such a conveying section, power is directly transmitted from a drive shaft to which the power of the engine is transmitted to an input shaft of the conveying section through a transmission chain. was configured (see, for example, Patent Document 1).

JP 2015-181388 A

In this type of peeling device, the corn tufts are supported from above by a feeding member so that they do not rise from the peeling rolls, and the peeling rolls perform the peeling. If the height of the feeding member with respect to the peeling roll is high compared to the thickness of the corn tuft, the bracts are not sufficiently peeled off because the feeding member tends to rise from the peeling roll. If the height of the feeding member relative to the peeling roll is lower than the thickness of the corn tufts, the seed grains of the corn tufts may fall off because the feeding member strongly presses the corn tufts against the peeling roll. be. Therefore, in order to eliminate such a disadvantage, it has been proposed to adjust the height of the conveying section with respect to the peeling roll according to the thickness of the corn tufts.

With the configuration for adjusting the height of the conveying section as described above, the vertical position of the input shaft of the conveying section is changed integrally. However, in the conventional transmission structure, power is transmitted from the drive shaft through the transmission chain to the input shaft of the conveying unit, and tension is applied to the transmission chain in order to ensure power transmission. will be Therefore, if an attempt is made to vertically change the position of the input shaft of the conveying section around which the transmission chain is wound, the tension force makes it difficult to change the circumference of the transmission chain, requiring a strong operating force. there was a face

Therefore, it has been demanded to be able to change and adjust the height of the conveying unit with respect to the peeling roll with a light operating force.

The characteristic configuration of the peeling device according to the present invention includes a peeling processing unit for receiving harvested corn tufts and stripping off the bracts of the received corn tufts, and a debarking processing unit provided above the husk processing unit. a conveying unit for conveying the corn tufts located above the dehulling processing unit from the starting end to the terminating end of the dehulling processing unit; and a power transmission for transmitting power from a driving source to the conveying unit. and a mechanism, wherein a plurality of peeling rolls extending along the conveying direction of the corn tufts are arranged in the left-right direction of the peeling processing unit in the peeling processing unit, and the conveying unit includes: , left and right side wall portions, an input rotating body extending along the lateral direction of the device and to which power from the power transmission mechanism is transmitted, and a corn bunch supported by the input rotating body and rotated together with the input rotating body. a conveying body that feeds the body, a frame that pivotally supports both left and right end portions of the input rotor and is supported by the left and right side wall portions so that the vertical position of the frame body can be changed, and a vertical position of the frame body. a vertical position adjusting mechanism for changing the height position of the conveying body with respect to the peeling roll by changing the height position, and the power transmission mechanism is supported by the side wall and transmits power from the driving source. a relay rotating body supported by the side wall portion in a state of being positioned between the driving rotating body and the input rotating body in the transmission path of the power transmission mechanism; the driving rotating body and the A first endless rotary body wound around the intermediate rotary body and a second endless rotary body wound around the intermediate rotary body and the input rotary body are provided. .

In this way, power transmission is performed via the relay rotor. When the vertical position of the frame relative to the side wall is changed in order to change the height of the conveying section with respect to the peeling roll, the position of the input rotating body is changed at the same time, and the tension state of the second endless rotating body is changed.

The second endless rotating body only transmits power from the intermediate rotating body to the conveying section, but the first endless rotating body may transmit power from the driving rotating body to devices other than the conveying section. Since it is necessary to reliably transmit power from the body, there is a possibility that a strong tension force is applied to the first endless rotating body.

When the vertical position of the frame body is changed, the winding state of the first endless rotating body does not change, and the position changing operation of the input rotating body does not change. As a result, there is little possibility that a large operating force will be required when changing the vertical position of the frame body.

Therefore, it is possible to change and adjust the height of the conveying section with respect to the peeling roll with a light operating force.

According to this configuration, the first endless rotating body can maintain a state in which tension is applied by the position-fixed idler ring, and can reliably transmit power from the drive shaft.

In the present invention, as the tension mechanism for applying tension to the second endless rotating body, the power transmission mechanism includes a tension wheel around which the second endless rotating body is wound, supported by the side wall portion, a tension arm for rotatably supporting the tension wheel.

According to this configuration, even if the position of the input rotor is changed, the change in the circumference is absorbed by the action of the movable tension wheel, and the tension of the second endless rotating body is automatically maintained in a favorable state. can do. Also, the tension wheel can be stably supported by the tension arm supported by the side wall.

In the present invention, it is preferable that an actuator capable of changing the vertical position of the frame body is provided.

According to this configuration, the vertical position of the transport section can be adjusted by operating the actuator. Since the change and adjustment of the height of the conveying section can be performed with a light operating force, a small actuator with a small operating force can be used.
