Abstract

PURPOSE:To achieve an efficient and effective selection work, by making a weight detector section of a container communicate with a mixing ratio measuring device to measure the crushed particle mixing ratio. CONSTITUTION:When material, a mixture of whole and crushed particles, is fed, crushed particles are selected with a rotating selection disc 7 and accumulated into a weighing container 18. A weight detector section C detects the weight of crushed particles in the container 18 with a load cell 19 and sends the signal thereof to a mixing ratio measuring device D and a measuring operator B. The detecting operation of the weight detector section C is interrupted by the signal from the operator B and the action of an automatic discharge valve 17, the crushed particles are accumulated into a receiving box 21. When the receiving box 21 is emptied and set in place again, on an ON signal of a microswitch 23, an automatic opening/closing valve 14 operates to feed whole particles in the machine frame 4 to the container 18 and moreover, on the ON signal thereof, the weight detector section C detects the weight of whole particles in the container 18. The mixing ratio measuring device D compares the resulting signal with the crushed particle signal previously inputted to compute the crushed particle mixing ratio and the results are shown on a display 20.

A crushed grain discharge section 13 is configured to discharge and supply the crushed grains from a crushed grain flow down trough 11 to a weight measurement section C via a discharge path 12, and a discharge port 15 equipped with an automatic opening/closing valve 4 at the bottom of the sorter frame 4. is provided to form a sorting discharge section 16 for discharging and supplying the sorted particles at the bottom of the machine frame 4 to the weight measuring section, and these are connected in relation to each other and as an integral part to form the sorting machine body section A. .

Next, a weighing container 18 equipped with an automatic discharge valve 17 is provided at the bottom of the sorting machine frame 4, and the container 18 is mounted on and integrally formed with a load cell 19 that forms a part of the weight detection section C. , the measurement is carried out by a signal from the measuring actuating device B, and the weight detecting section C consisting of the load cell 19 is connected to a mixing rate measuring device to calculate the crushed particle mixing rate and displaying it on the display 20. , 21 is a receiving box for taking out sorted grains, 2
2 is an electric motor, and 23 is a detection microswitch that is in contact with the receiving box 21.

With the above-described configuration, when an arbitrary predetermined amount of raw grain consisting of a mixture of sorted grains and crushed grains is put into the supply hopper 3 and the device is started, the mixed grains flow down to the bottom of the sorter frame 4. A grain layer is formed in an inclined shape, and each pocket-shaped pot hole 6 provided in a sorting disk 77 that rotates within the grain layer once collects each grain into the pot hole 6...・Inserted into disk 7
, respectively, move upward by the rotation of . At this time, the long particles are quickly dropped out of the pot hole 6 of the sorting disk 7 and fall onto the upper surface of the grain layer, while the crushed coarse particles remain immersed in the pot hole 6 and rotate. The crushed particles fall from the higher part into the crushed particle flow lower gutter 11 in a transfer pattern, and while sliding in the gutter 11, they flow down through the discharge path 12 into the metering container 18 at the lower part and are accumulated. .

On the other hand, the weight detection section C detects the weight of the container 1 using the load cell 19.
The weight of the crushed particles accumulated in the chamber 8 is detected, and the detection signal is input to the mixing rate measuring device and the measuring actuator B, and the detection signal is maintained in a constant state for an arbitrary predetermined period of time (for example, 30 seconds). When continuing (meaning the end of the crushing and sorting action on the mixed grains), the detection action of the weight detection/output unit C1 is interrupted by a signal from the actuating device B, and the automatic discharge valve 17 provided in the weighing container 18 is stopped. is operated to open and close, and the crushed particles in the container 18 whose weight has been detected are discharged and flowed down into the lower take-out receiving box 21 and accumulated therein. Therefore, the receiving box 21 was taken out from inside the machine and the crushed particles inside were completely removed.
