Description

[Detailed description of the invention] [Industrial application field] The present invention is a huller sorting machine which, after removing the paddy using a removing mechanism, sorts and takes out brown rice from the removed rice. This invention relates to a device for attaching and detaching a rotating sorting cylinder.

[Conventional technology]

In recent years, a rotary sorting machine has been developed in which a brown rice catcher is installed inside a horizontal rotating sorting barrel with many recesses formed on the inner circumferential surface as a sorting machine for sorting and extracting brown rice from the rice that has been removed. It was done.

As shown in Fig. 7, this rotary sorting machine has a pair of left and right rotating rollers D, D provided in a box-like case C.
The sideways rotary sorting cylinder A is configured to rotate while being supported by the front end side of the edge member and the lower surface part of the rear end side. Mixture) is fed, and while the fallen rice moves to the discharge side of the rotary sorting cylinder while forming a fluidized bed that repeats the flow of being scraped up to a certain height and then falling to the bottom, the fallen rice fits into the recess. Taking advantage of the phenomenon that brown rice is raked up to a high position and then falls, and paddy can only be raked up to a lower height than the brown rice, the brown rice that is raked up to a high position and then falls is placed in the brown rice receiving trough. It is received at the station and taken out of the aircraft.

Incidentally, in order to inspect and clean the interior of the rotary sorting cylinder A and the box-like case C, there has been a demand for the rotary sorting cylinder A to be inserted into and removed from the box-like case C along its axial direction.

As the prior art, the present applicant previously filed a patent application
In No. 60-27351, in order to support the rotary sorting cylinder stably and smoothly without damaging the body part of the rotary sorting cylinder, as shown in FIG.
It was proposed that a pair of left and right guide rails B, B be arranged parallel to each other with an appropriate distance between them at the bottom of the vehicle.

[Problem that the invention attempts to solve]

However, in the prior art, when inserting the rotary sorting cylinder A into the box-like case C, for example, the lower surface of the edge member of the rotary sorting cylinder A shown by the dashed line in FIG. Push the rotary sorting cylinder A into the lower surface of the body on the tip side as shown by the solid line in FIG.
In order to place it on D, it is necessary to lift it by a dimension h1 in the vertical direction.

However, even if the radial gap h2 between the upper surface of the left and right guide rails B and the lower surface of the rotary sorting cylinder A is small, the vertical dimension h1 is considerably larger than h2. Therefore, if the difference is large, the end face of the diameter part on the tip side of the rotary sorting cylinder A will collide with the end face of the diameter part of the rotary roller D, and it will take a lot of effort to lift the tip side of the rotary sorting cylinder A. On the other hand, when removing it, the impact when it falls from the rotating roller D onto the guide rail B increases, increasing the risk of accidents such as damaging or deforming the rotating sorting cylinder. Ta.

The present invention aims to solve the above-mentioned problems by reducing the gap between the guide rail and the rotary sorting cylinder, and also by reducing the drop when the rotary sorting cylinder is attached to and removed from the rotating roller.

[Means for solving problems]

Therefore, in the present invention, a horizontally oriented rotating sorting cylinder with a large number of recesses formed on its inner peripheral surface is arranged in a box-like case, and a brown rice receiving trough that runs along the axial direction of the rotating sorting cylinder is arranged. The lower part of the rotary sorting cylinder is rotatably supported by a pair of left and right rotating rollers provided in the box-like case, while the rotary sorting cylinder is inserted and removed from an opening on one side of the box-like case along its axial direction. In the rice hulling sorting machine configured to be freely movable, the box-like case has a position approximately in the center between the left and right pairs of rotating rollers, so that when the rotary sorting cylinder is inserted or removed, the most suitable position of the rotary sorting cylinder is located. A guide rail is provided to slidably support the lower part along its axis, and the guide rail is formed into an upward groove shape in cross section.

[Functions and effects of the idea]

According to the present invention, only one guide rail is provided between the left and right pair of rotating rollers that support the rotating sorting cylinder during rotation work, and approximately directly below the axis of the rotating sorting cylinder. Even if the vertical gap between the lower surface of the sorting cylinder and the guide rail is reduced, the gap between the lower surface of the rotary sorting cylinder supported on the left and right pair of rotating rollers and the guide rail can be maintained. Therefore, the end face of the diameter part on the tip side of the rotary sorting cylinder supported by the guide rail can be smoothly transferred to the upper surface of the rotary roller without colliding with the diameter part of the rotary roller during insertion. Even when the rotary sorting cylinder placed on the upper surface of the rotary roller is removed, the drop between the guide rail and the lower surface of the rotary sorting cylinder is small, so the rotary sorting cylinder can be transferred to the guide rail without increasing the impact.

In this way, the work of inserting and removing the rotary sorting cylinder can be carried out smoothly and easily, and it is also possible to prevent damage to the rotary sorting cylinder due to the work of inserting and removing it.

In addition, since there is only one guide rail, the structure inside the box-like case is significantly simpler compared to the conventional case with a pair of left and right guide rails, and the inside of the box-like case can be cleaned easily. At the same time, the weight of the rice hulling and sorting machine is also reduced.

Furthermore, since the guide rail of the present invention has an upward groove-shaped cross section, the rotary sorting cylinder is supported on both the left and right upper surfaces of the guide rail, so there is no concern that the rotary sorting cylinder will roll left and right. It is possible to avoid this problem and provide a stable guiding effect similar to the conventional pair of left and right guide rails.
