Description

[Detailed Description of the Invention] The present invention relates to an attachment/detachment device for a sorting barrel in a cylindrical grain sorter.

Conventionally, in this type of cylindrical grain sorting machine, one end of the sorting barrel is used as the supply side and the material to be sorted flows into the inner peripheral surface of the sorting barrel, so a support device is used to rotate the material into the sorting barrel. If this happens, it will get in the way of the inflow of the material to be sorted, causing a phenomenon of accumulation of the material to be sorted, making it undesirable for a smooth inflow of the material. In the case of a device supported by wheels, the device that rotatably supports the wheels and the outer peripheral surface of the sorting cylinder that comes into contact with the wheels must be formed into a perfect circle to ensure smooth rotation. Processing technology was required.

Therefore, in order to overcome the above-mentioned conventional drawbacks, the present invention has an outer circumferential surface that is the inner circumferential surface of the sorting barrel, and an inner circumferential surface that is the outer circumferential surface of the fixed cylinder installed horizontally in the machine casing toward the discharge side. It is made removable by a supporting annular body configured to rotate and slide so that it can move in and out of the sorting cylinder side, and on the discharge side, the boss part provided at the axial center of the sorting cylinder is inserted into and removed from the drive shaft. It is an object of the present invention to provide a sorting cylinder attachment/detachment device which is intended to solve the above-mentioned conventional drawbacks by cooperating with a flexible configuration.

The present invention will be explained below with reference to embodiment drawings.The cylindrical grain sorter referred to in the present invention has a large number of sorting holes drilled on the circumference of a rotatably horizontal sorting barrel. The material may be sorted by leakage from this sorting hole, or it may be a method in which a large number of depressions are formed on the inner circumferential surface and the material is sorted by the scooping action of these depressions. The screening portion described in the present invention means these screening holes or depressions.

Therefore, the sorting portion shown in the embodiment refers to the former sorting hole, and a cylindrical grain sorting machine configured to sort by leakage will be explained.

1 is a rectangular machine case with an open top, the bottom of which is in the shape of an inverted U-shape, and in the center of the bottom, a transverse feed path 3 with a built-in screw conveyor 2 is installed horizontally from the supply side X to the discharge side Y; At the end (discharge side Y) of this cross-feeding path 3, a lifting path 4 communicating therewith is provided in the vertical direction.

Reference numeral 5 denotes a sorting cylinder, and a large number of sorting holes 6 of an appropriate width and elongated shape in the rotating direction of the sorting cylinder 5 are bored in a staggered manner on the circumferential surface, and a boss portion is provided at the axis of the sorting cylinder 5 on the discharge side Y. 7 is provided by a support rod 8. Reference numeral 9 denotes a drive shaft that is supported by the machine casing 1 on the discharge side Y and rotates in a state of protruding inward, and has a rectangular fitting portion 9 at the inner tip.
a is formed. The boss portion 7 is formed in a rectangular hole corresponding to the fitting portion 9a, and the boss portion 7 is configured so that it can be freely fitted into and removed from the fitting portion 9a only in the axial direction of the sorting cylinder 5. This is an annular cover that covers the drive shaft 9.

Next, the supply side X of the sorting cylinder 5 is formed into a tapered part 11 for receiving the objects to be sorted, and furthermore, a support part 12 extending parallel to the axial direction of the sorting cylinder 5 is provided. 1
Reference numeral 4 denotes a fixed cylindrical body, which is installed horizontally on the supply side X side wall 13 of the machine casing 1, with the axis line of the sorting cylinder 5 as its center line, toward the discharge side Y; and 15, a support annular body; The outer circumferential surface of the cylinder 5 slides on the inner circumferential surface of the support part 12 of the sorting cylinder 5 so as to be rotatable and slidable therebetween, and the inner circumferential surface thereof is rotatable and slidable with respect to the outer circumferential surface of the fixed cylinder 14. It is constructed so that it can be polymerized and moved freely toward and away from the sorting cylinder 5 side. Reference numeral 16 denotes a guide groove diagonally bored in this support annular body 15, and reference numeral 17 denotes a protrusion protruding from the inner peripheral surface of the discharge side Y of the fixed cylindrical body 14 so as to look into the guide groove 16. be. Further, reference numeral 18 is a lever for extending and retracting that projects from the outer peripheral surface of the support annular body 15.

19 is an opening bored in the side wall 13; 20 is a tank with telescopic legs 20a whose supply port 20b can be inserted into the opening 19; and 21 is a wing nut for fixing the tank 20.

In addition, M is a prime mover, 22 is a transmission part which rotates the screw conveyor 2 from the prime mover M, and 23 is an intermediate shaft which receives the power of this transmission part 22 and derives the power from the supply side X to the discharge side Y. , 24 is the discharge side Y
In the transmission part 1a, which rotates the drive shaft 9 from the intermediate shaft 23, is a cover that covers the upper open part of the machine casing 1.

Since the configuration of the present invention is as described above, first, with the cover 1a removed, the boss portion 7 is fitted on the discharge side Y of the sorting cylinder 5 to the fitting portion 9a of the drive shaft 9, as shown in FIG. When the lever 18 is gripped and rotated in the direction shown by the arrow A in FIG.
The support portion 12 protrudes to the side as shown by the solid line in FIG.
The supply side X of the sorting cylinder 5 is rotatably supported and mounted.

Therefore, the materials to be sorted that are put into the tank 20 are sequentially supplied to the inner circumferential surface of the sorting cylinder 5 from the supply port 20b on the inner circumferential surface of the support annular body 15. In this case, the power of the prime mover M is transferred to the transmission section 22, the intermediate shaft 23, and the transmission section 24.
Since the boss portion 7 of the sorting cylinder 5 is connected to the fitting portion 9a of the driving shaft 9 at mutually square portions, the sorting cylinder 5 rotates and the traversing path 3 lifts. The upper path 4 is also in operation, and while the materials to be sorted supplied to the sorting cylinder 5 flow toward the discharge side Y, those that pass through the sorting hole 6 flow down along the bottom and into the cross-feeding path 3. After being transferred to the lifting path 4 from the entry end and being lifted up, those that are taken out to an appropriate location and do not leak from the sorting hole 6 flow inside the sorting barrel 5 to the discharge side Y and are separated outside the machine casing 1. taken out.

In addition, when removing the sorting cylinder 5 and replacing it with another sorting cylinder with a different sorting hole 6, or cleaning it, the ejection rod 18 should be rotated away from the direction A in FIG. As shown in FIG. 2, the support annular body 15 retracts toward the fixed cylinder 14 and comes out of the support portion 12. At this time, if you hold the sorting cylinder 5 and pull it in the supply side X direction, the discharge side Y
The boss portion 7 can also be removed from the drive shaft 9, and the sorting cylinder 5 can be removed.

As mentioned above, the present invention consists of a sorting cylinder with a large number of sorting parts formed on its circumferential surface mounted rotatably horizontally in the machine casing, one end of which is used as a supply side for grains to be sorted, and the other end used as a discharge side. In this apparatus, on the discharge side of the sorting cylinder, a boss provided at the axis of the sorting cylinder can be freely inserted into and removed from a drive shaft mounted on the machine casing, and on the supply side, the outer peripheral surface is connected to the inner periphery of the sorting cylinder. A support annular body whose surface and inner circumferential surface are rotatably and slidably overlapped with the outer circumferential surface of a fixed cylinder installed horizontally in the machine casing toward the discharge side, and which is configured to be movable in and out of the sorting barrel side. Since it is made removable, it not only solves the drawbacks of the conventional system as described at the beginning of this column, but also allows the materials to be sorted to flow smoothly into the sorting cylinder. Since all you have to do is turn the ejector rod, attachment and detachment on the supply side is easy, and in conjunction with the detachable structure on the discharge side, it becomes even easier to attach and detach the sorting cylinder. It was.

The sorting cylinder in this embodiment has been described with the supply side placed at a slightly higher level than the discharge side, but if it is horizontally mounted, the supply side of the sorting cylinder may be placed on the discharge side or the supply side. Needless to say, it is sufficient to provide an appropriate member to prevent movement in the direction.

In addition, in the description of the scope of claims for utility model registration, the reference numerals attached to the drawings are also written for ease of understanding, and the interpretation is therefore limited to the structure shown in the drawings.
