Description

[Detailed explanation of the idea] The present invention relates to a testing grain sorting device.

In other words, in test grain sorting equipment used in hulling plants, etc., in which a certain amount of unweighed rice can be sorted on a trial basis and the yield can be determined. The grains remaining inside the sorting cylinder can be discharged reliably and smoothly, and the discharge work can be performed automatically, and the sorting work can be easily performed, making it suitable for a simple structure. It is provided so that it can be implemented.

Next, the embodiment shown in the drawings will be described.

Fig. 1 shows a side view of the whole, and a sorting tube A is installed inside a box-shaped case C having supporting legs 4, and a sorting tube A has a long sorting hole in the side surface of the sorting tube A like the conventional type. 1, and a tapered surface is formed around the discharge opening 3 on the discharge side and the receiving opening 6 on the receiving side, which are opened, and a center supported by a plurality of arms 5 on the inside of the receiving opening 6 side. A rotary drive shaft 2 is fitted and fixed on the boss 7, and the sorting cylinder A is supported and installed horizontally by the shaft 2, and a motor M is mounted on the other side of the support 8 on which the shaft 2 is installed. The shafts 2 are connected in series and installed so that the shaft 2 can be rotationally driven through the support body 8 by a motor M.
Support shafts 9, 9 extending from the support body 8 to both sides are mounted on metals 10, 10 on both sides inside the case C, and when a lever 11 fixed to the outer end of one of the support shafts 9 is rotated, the support is activated. The sorting tube A and the motor M are installed so that they can rotate with the shaft 9 as a fulcrum O.

The side part of the cover 12 installed to cover the sorting tube A is fixed to the support 8, and an outlet 13 is formed in the flat part of the cover 12 below the sorting tube A. An outlet 14 is formed at the lower side of the cover 12, which is the lower part of the outer side of the discharge opening 3 of the cylinder A, and an anti-clogging rubber 15 is formed in the upper part of the cover 12, which contacts the outer peripheral surface of the sorting cylinder A.
The tank 16 attached and fixed to the cover 12 is the case C.
A charging gutter 19 is installed so as to protrude upward through an opening 17 in the upper part of the tank 16, and a charging gutter 19 formed extending from the lower part of the tank 16 having a shutter 18 is installed so as to look inside the receiving opening 6 of the sorting cylinder A. However, as shown in FIG. 3, the entire center of gravity G is located at a position slightly closer to the sorting cylinder A than the fulcrum O.

Further, a projecting piece 20 is provided to protrude laterally from the lower part of the motor M, and the attitude switching device E is configured to be detachable from the projecting piece 20.

That is, this attitude switching device E has one end of a stopper 22 pivotally attached to the center of a support shaft 21 attached to and detachable from a protrusion 20, and an operating rod 2 that moves in and out from a solenoid B fixed below.
3 is connected to the other end of the stopper 22 with some play.

Then, when the switch S operated from the outside is pressed, the solenoid B is activated after a certain period of time according to the timer, the stopper 22 is released from the protrusion 20, and the sorting tube A in the horizontal position is moved downward with its discharge side. The structure is configured to change to a tilted posture.

Both document receiving boxes 24 and 25 are installed below the cover 12 under the case C, and the lower part of the cover 12 extends above the receiving boxes 24 and 25 through the lower opening 26 of the case C. , the inclined side of the cover 12 is installed so as to touch the edge of the lower opening 26.

Therefore, during the test work, as shown in FIGS. 1 to 3, with the sorting tube A rotatable around the fulcrum O and everything else in a horizontal position, the stopper 22 of the posture switching device E is moved between the protrusions 2 and 3. and lock it in place.

In this state, a certain amount of unweighed rice for testing is put into the tank 16 with the shutter 18 closed, the sorting tube A is rotated by starting the motor M, and the shutter 18 is opened to feed the sorting tube A from the input gutter 19. At this time, press the switch S.

Therefore, the grains that are sorted by the sorting tube A and leak from the sorting hole 1 fall into the receiving box 24 from the outlet 13, and the grains that do not leak from the sorting hole 1 remain in the sorting tube A. Sorting tests can be used to sort grains and check yield.

When a certain period of time has elapsed, which is the time at which this sorting is completed, the timer has elapsed since the switch S was pressed, and the solenoid B is activated, causing the retraction of the operating rod 23, as shown in FIG. The stopper 22 rotates due to the closing action and releases the locking of the protrusion 20, so that the sorting cylinder A on the side of the center of gravity G rotates around the fulcrum O, and the tank 1
6 is in contact with the edge of the opening 170, and the lower part of the cover 12 is in contact with the edge of the lower opening 260, so that the sorting tube A is tilted, so that the grains in the inclined sorting tube A are transferred from the discharge opening 3 to the outlet 14. It leaks out and falls into the receiving box 25.

Further, the lever 11 can then be used to rotate the entire device into a horizontal position, and the stopper 22 can be engaged to set the device in a state for the next work.

In this way, the present invention has a sorting tube with a large number of sorting holes formed on its circumferential surface, and the shaft is horizontal and can be rotated by a motor. The center of gravity is held at the position of , the sorting tube is made to be tilted freely around the fulcrum, and the side of the fulcrum opposite to the sorting tube is configured to be freely engageable and detachable from the attitude switching device, and between the attitude switching device and the switch. Since it is constructed by interposing a timer into the grain, after the sorting operation, the grains remaining in the sorting tube can be reliably and smoothly discharged by rotating the sorting tube around the fulcrum and tilting it. When a certain period of time has elapsed for the sorting by the sorting cylinder to be completed, the position switching device activated by a timer using a switch is released and the sorting cylinder on the side of the center of gravity is automatically tilted. It has the features that the work can be completed reliably without any operation, the discharge work can be performed well, the sorting work can be easily performed, and it can be carried out suitably with a simple structure.
