Description

[Detailed Description of the Invention] The present invention relates to an improvement of a transmission device installed in a narrow space between the main body of the oscillating sorting huller and the lifting device.

Conventionally, in an oscillating sorting huller, the transmission device for each rotating part is installed in a narrow space between the huller body and the lifting device, so when changing the rotation speed of each rotating part, This was a very time-consuming and troublesome task, as it required removing the lifting device and then removing the nearby pulley and belt.

The present invention aims to provide a transmission device in which the speed change pulley is configured as a split pulley by adjusting shims, so that the rotation speed can be changed by simply removing a portion of the pulley.

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the drawings.

In the figure, reference numeral 1 denotes a hulling device installed on a machine stand 3, which presses and removes the rice falling from a funnel 7 provided above between dehulling rolls 11 and 11 provided in a dehulling section 9. . 13 is a winnowing machine that generates a sorting wind to sort out the paddy hulls mixed in the removed rice, 15 is a conveying device that conveys the mixed rice containing paddy and brown rice to the lifting device 17, and 19 is a hulling device. This is a swinging sorting device installed on a hollow frame 21 fixedly attached to a machine stand 3 on the side of the rice cracker 1, and a paddy outlet 23 is provided so as to look above the funnel 7. The lifting device 17 is provided on the machine stand 3 and is used to transfer the scraped rice sent from the transfer device 15 to the supply tank 25 provided above. 27 is a receiving tank provided below the supply tank 25.
Reference numeral 29 denotes a prime mover such as a motor installed inside the hollow frame 21, which drives the operating parts of the hulling device 1, the swing sorting device 19, and the lifting device 17 via a transmission device 31. The transmission device 31 is provided between the huller main body having the huller removal device 1 and the swing sorting device 19, and the lifting device 17, and the transmission path is connected to the pulley 33 of the prime mover 29 as shown in FIG. A belt 37 is suspended between the main shaft pulley 35 and
A belt 43 is suspended between the main shaft pulley 35, the winch pulley 39, and the driven pulley 41, and a belt is suspended between the speed change pulley 45, which is provided coaxially with the driven pulley 41, the elevator pulley 47, and the swing device pulley 49. 51 is suspended, and a belt 57 is also suspended between a pulley 53 provided coaxially with the elevator pulley 40 and a conveyance pulley 55, thereby transmitting the power of the prime mover 29 to each rotating part. 5
9 and 61 are tension pulleys. The speed change pulley 45 is constructed as follows. That is, as shown in FIG. 3, it is formed into a split pulley,
The split pulley 45a on one side is fixed to the driven pulley 41, the split pulley 45b on the other side is detachably attached to the driven shaft 63, and the shim 65 is interposed between the split pulleys 45a and 45b to change the pulley diameter. I am trying to change the rotation speed by changing the rotation speed. 67
69 is a bolt hole for integrally attaching the split pulleys 45a, 45b and the shim 65, and 69 is a tightening bolt.
71 is a tightening bolt for fixing the other side pulley 45b to the driven shaft 63.

In the above configuration, when adjusting the rotation of the transmission device 31, by inserting a shim 65 of an appropriate thickness between the split pulleys 45a and 45b, the pulley diameter of the speed change pulley 45 is changed and the rotation speed can be changed. It will be done.

As described above, the present invention provides a rice hulling machine in which a transmission device is provided between the rice hulling machine main body and a lifting device, in which the speed change pulley of the transmission device is formed into a split pulley, and a shim is provided between the split pulleys. Since the transmission device is capable of changing speeds by interposing the speed change pulley, the rotation speed can be changed by simply removing a part of the speed change pulley. Moreover, when the interval between the split pulleys is widened in order to change the rotation speed, a shim can be interposed between the split pulleys. Therefore, the shim can be held in contact with the inner surfaces of the split pulleys, and the distance between the split pulleys can be maintained reliably by the shim. Therefore, there is no runout between the split pulleys, and the rotational speed can be changed stably.

The present invention is not limited to the above-mentioned embodiments, and the present invention can be implemented in modes other than the above-mentioned embodiments.
