Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention uses a large number of pot holes in the inner peripheral surface to sort brown rice from the scraped rice after hulling in a huller. The present invention relates to an improvement of a rice hulling sorting device using a rotary grain sorting machine in which a rotary sorting cylinder is disposed horizontally and a brown rice receiving trough with an open top is disposed inside the sorting cylinder.

[Conventional technology]

As mentioned above, conventional hulling sorting equipment using a rotary grain sorter is used to sort out husked rice or brown rice, for example, as disclosed in Japanese Utility Model Application Publication No. 151648/1983 and Japanese Unexamined Utility Model No. 151649/1983. As stated in the publication, etc.
A large number of pot holes are formed on the upper surface of the wind sorting box that incorporates a wind sorting section for wind-selecting the rice that has been removed from the huller, and on the inner peripheral surface of the huller and the horizontal rotating sorting barrel. In addition, a rotary grain sorter having an open-top brown rice receiving trough inside the sorting barrel is arranged side by side, and the sorting barrel in the rotary grain sorter is a box-shaped grain sorter. Inside the cover frame, the rollers are rotatably placed on the upper surface of the wheels provided on both the left and right sides at the bottom of both ends of the sorting cylinder, while the outer periphery of one end of the sorting cylinder is provided with wheels on both the left and right sides of the one end. A flange that contacts the inner side of both sides of the wheel is attached to the outer periphery of the other end of the sorting barrel, and a flange that contacts the inner side of both the left and right wheels at the other end. By providing respective flanges to prevent the rotating sorting cylinder from moving in the thrust direction.

[Problem to be solved by the invention]

As described above, configuring the sorting cylinder in the rotary grain sorter to be covered with a box-shaped cover frame has advantages such as improving work safety. Because the many pot holes on the inner surface are blocked by the adhesion of bran, etc. that has peeled off from the brown rice, this sorting barrel must be periodically removed from the cover frame and its inner surface It is necessary to perform cleaning to remove any deposits, and the sorting cylinder may also be replaced depending on the type of paddy being handled.

On the other hand, in the conventional hulling and sorting device described above, of the left and right side plates of the cover frame of the rotary grain sorting machine installed in parallel with the hulling machine, the side plate on the side opposite to the hulling machine is , a scraped rice supply section is provided in the sorting cylinder, and an upper end of a scraped rice lifting mechanism for frying the scraped rice that has been wind-selected in the wind sorting section is communicated with the scraped rice supply section. Therefore, when cleaning or replacing the sorting cylinder, it is necessary to disassemble the communicating part of the scraped rice lifting mechanism to the scraped rice supply section one by one. , there was a problem that it took a lot of effort and time.

An object of the present invention is to provide a rice hulling sorting device that solves this problem.

[Means to solve the problem]

In order to achieve this object, the present invention provides a structure in which the huller and the inside of the horizontal rotating sorting barrel are mounted on the upper surface of the wind-selecting box which includes a wind-selecting section for wind-selecting the rice scraped from the huller. A rotary grain sorter having a large number of pot holes formed on the circumferential surface and a brown rice catcher with an open top surface inside the sorting barrel is arranged side by side, and this rotary grain sorter is arranged side by side. The sorting cylinder of the sorting machine is rotatably placed in a box-shaped cover frame on the upper surface of rollers provided on both left and right sides at the bottom of both ends of the sorting cylinder, and on the outer periphery of one end of the sorting cylinder. is a flange that contacts the inner side of both sides of the left and right wheels at the one end, and a flange that contacts the inner side of both sides of the right and left wheels at the other end, and a flange that contacts the inner side of both sides of the left and right wheels at the other end. In the hulling and sorting device, each of which is provided with a flange that comes into contact with the inner side surface of the rice hull, the side plate on the hulling machine side of the left and right side plates of the cover frame is provided with a side plate that is used for sorting in the rotary grain sorting machine. A scraped rice supply section is provided in the barrel, and an upper end of a scraped rice lifting mechanism for hoisting the scraped rice that has been wind-selected in the wind sorting section is communicated with the scraped rice supply section. On the other hand, a mounting hole having a larger diameter than the flange on the outer periphery of the sorting barrel is bored in the side plate on the side opposite to the huller side of the left and right side plates of the cover frame, and the mounting hole is A removable cover plate is attached to cover the area, and
The distance between the inner peripheral edge of the mounting hole and the outer peripheral surface of the sorting cylinder is made smaller on the lower side of the sorting cylinder and larger on the upper side of the sorting cylinder.

[Action/effect of the invention]

With this configuration, when cleaning or replacing the sorting barrel in the rotary grain sorter, remove the cover plate attached to the side plate on the opposite side of the cover frame from the huller side and start sorting. By opening a mounting hole with a larger diameter than the flange on the outer periphery of the barrel and then lifting one end of the sorting barrel on the mounting hole side, the flange at one end is attached to both sides of the one end. By pulling the sorting cylinder after removing it from the wheel, the sorting cylinder can be pulled out from the mounting hole in the opposite direction to the huller. Insert the other end into the mounting hole,
Once supported against the inner peripheral edge of this mounting hole,
By pushing the other end into the cover frame with the other end slightly lifted, the flange on the outer periphery can ride over both wheels, and in this state, the cover can be installed by pushing it further into the cover frame. When cleaning or replacing the sorting cylinder, the sorting cylinder can be attached and detached without having to disassemble the communicating part of the scraped rice lifting mechanism to the scraped rice supply section each time, as in the past. It is possible.

However, in the case where a mounting hole having a larger diameter than the flange on the outer periphery of the sorting barrel is bored in the side plate of the cover frame on the side opposite to the huller side, the inner peripheral edge of the mounting hole and the sorting When the distance between the cylinder and the outer circumferential surface of the cylinder is made small over the entire circumference of the sorting cylinder, when removing the flange at one end of the sorting cylinder from both wheels when pulling out the sorting cylinder, When one end of the sorting cylinder is lifted, the upper part of the flange comes into contact with the inner peripheral edge of the mounting hole, resulting in a problem that the sorting cylinder cannot be pulled out.

When the distance between the inner circumferential edge of the mounting hole and the outer circumferential surface of the sorting cylinder is increased over the entire circumference of the sorting cylinder, the above-mentioned problem does not occur. At the end of the period, when the other end of the sorting cylinder falls until it comes into contact with the inner circumferential edge of the mounting hole, the falling height becomes high, increasing the risk of damaging the sorting cylinder. When mounting the sorting cylinder, the other end of the sorting cylinder is inserted into the mounting hole, and is temporarily supported against the inner peripheral edge of the mounting hole. When lifting the flange to a height that allows it to pass over both wheels, the lifting height becomes high, which causes a problem in that it becomes difficult to attach the sorting cylinder.

In contrast, the present invention does not make the distance between the inner peripheral edge of the mounting hole and the outer peripheral surface of the sorting cylinder the same over the entire circumference of the sorting cylinder,
The structure is such that it is small on the lower side of the sorting cylinder and large on the upper side of the sorting cylinder.
When the sorting cylinder is pulled out, when the sorting cylinder is lifted, the flange on its outer periphery can be prevented from coming into contact with the inner peripheral edge of the mounting hole. It is possible to reduce the falling height when the other end of the sorting cylinder falls until it touches the inner peripheral edge of the mounting hole, and when installing the sorting cylinder, the other end of the sorting cylinder can be placed in the mounting hole. Since it is possible to lower the height at which the flange is lifted up from the state where it is once supported against the inner circumferential edge of the cylinder to the height where the flange crosses both wheels, attaching and removing the sorting cylinder from the mounting hole will prevent damage to the sorting cylinder. This can be done easily and reliably without having to do anything.

Therefore, according to the present invention, the sorting cylinder can be cleaned or replaced very easily and quickly without the risk of damaging the sorting cylinder.
