[Industrial applications]

 The present invention relates to a hulling machine, and more particularly to a caster loading / unloading device for a hulling machine.

[0002]

[Prior Art]

 Conventionally, in a huller that has a hulled brown rice sorting unit such as an oscillating sorting device on one side of the hulling unit consisting of a removing device and a main wind selecting device, the hulling machine bottom It is well known to provide a pair of casters for movement. Moreover, this caster works as a caster when moving, but when it is stationary and moved, it is stored in the huller and the whole huller is installed horizontally.

As such a caster loading / unloading device, a pair of casters mounted on an arm and provided at the bottom of the huller to be freely moved in and out is moved up and down by a jack mechanism, and a spring or an overlap is mounted on the arm equipped with the casters. Connecting and lifting one side of the hulling machine and letting the caster move in and out by the biasing force of the spring or the overlapping (Actually open 61-64339, 61-87530, 56-147806, 57-62637) (See etc.), a long lever is connected to the free end of the arm equipped with casters, and by pushing down this lever, the casters can be raised and lowered by the casters to move in and out ( For example, see Japanese Utility Model Laid-Open No. 57-131839).

[0004]

[Problems to be solved by the device]

 By the way, in the case of using the above-mentioned jack mechanism, the casters can be safely and easily moved in and out by operating the screw shaft, but it is difficult to take a relatively long time. If the arm is biased by a spring or a weight, it is necessary to switch the caster out / in (switching the spring or the biasing direction of the stack). One side needs to be lifted by hand, and it is not easy for an old man or a woman to lift it alone. In addition, in the above case, since the long lever is rotated, it is necessary to provide the lever so as not to come into contact with the grain elevator, etc. so as to project from the front and back sides of the grain huller. The drawback is that the long lever is an obstacle.

In view of the above problems, the present invention provides a caster loading / unloading device for a hulling machine that does not become a hindrance except when moving, does not need to be lifted by hand, and operates quickly (one-touch). To do this is a technical issue.
