Description

[Detailed description of the invention] The present invention relates to an improvement in a grain discharging device for a dehulling and sorting machine.

Generally, at the beginning of operation of a dehull sorting machine, incompletely sorted grains flowing out from the sorting disk are returned to the conveyance process of mixed paddy and brown rice by operating a switching valve until the sorting condition on the sorting disk becomes good.
After the sorting is good, it is customary to change the drain and take the brown rice out of the machine.

For example, in the known example shown in FIG.
A switching valve 74 for changing the flow path of brown rice is provided in the discharge gutter 73 of
(See Fig. 2) is introduced into a mixed paddy/brown rice flow path 76, and when the sorting becomes good, the switching valve 74 is operated again to take out the brown rice from the machine.

Further, the unhulled and brown rice mixed rice that has been removed from the husks and wind-selected from the husks 67 and the wind-selecting room 69 is put into the mixed rice adjustment tank 72 by the mixed rice elevator 70; , is suspended from the mixed rice elevator 70 with a spring bias, and is connected to the control valve 68 of the paddy supply section 80 through an interlocking device Wi 71, and discharges the paddy, brown rice, and mixed rice stored in the mixed rice adjustment tank 72. The amount of raw material paddy supplied to the dehulling chamber 67 is automatically controlled to ensure a storage volume that is approximately the same as the flow rate, thereby preventing abnormal loads caused by excessive supply of raw material paddy and preventing operation stoppage accidents. Measures are being taken.

By the way, because of the above-mentioned configuration, the incompletely sorted grains at the initial stage of operation are flowed into the paddy/brown rice mixed rice flow path 76 and merge with the paddy/brown rice mixed rice flowing down from the wind selection chamber, and the grain size is about twice that of normal. Even if it is only for a short time until the flow rate flows into the mixed rice elevator and the supply control effect of the mixed rice adjustment tank 72 reacts, a large-capacity mixed rice elevator is required, and the mixed rice adjustment tank 72 requires a large capacity mixing rice elevator. Since it is unavoidable to have a margin for the storage capacity, the capacity must be increased, and the elevator must be raised to increase the volume of the entire device, making the configuration costs and packaging and transportation costs high relative to the capacity, and installation costs.・There were drawbacks such as a large storage volume.

In order to solve the above-mentioned drawbacks, the present invention provides a storage chamber at the discharge port of a rice lifter for brown rice that preferentially lights up the incompletely sorted grains flowing out from the sorting board at the beginning of operation, resulting in good sorting. By overflowing the brown rice from the storage chamber and taking it out of the machine, it is possible to omit the operation of the switching valve to change the flow path at the beginning of operation, and at the same time, the incompletely sorted grains stored in the storage chamber before the end of operation can be used for frying for mixed rice with paddy and brown rice. The rice is returned to the machine's supply path for re-sorting, eliminating oversupply of paddy/brown rice mixed rice to the conveyance process, and reducing the volume of the height 8 of the rice lifting machine for paddy/brown rice mixed rice and the mixed rice adjustment tank. The purpose of this project is to develop and provide a discharge device for a slag removal sorter that can be used in a variety of ways.

The present invention will be explained based on embodiment figures. Reference numeral 59 in FIGS. 3 to 5 denotes a dehulling machine, and a prime mover 56 and a staking hopper 2 are placed on the upper wall surface of the box-shaped machine frame 1 of the hut 59, and raw paddy is loaded into the staking hopper 2. When the paddy is loaded and the shutter 3 is pulled, the flow rate of the paddy is controlled by the control valve 26, and the paddy passes between the dehulling rolls 6.7 installed opposite to the dehulling chamber 8 and passed through the dehulling rolls 6.7 and 1112.
Framed. And, the things that are removed from the school are from the removal room 8D to the wind selection room 13.
The rice husks with low specific gravity are eliminated! Immature grains, which are sucked into the I machine 10 and discharged outside the machine, are discharged from the immature grain discharge port 12, which is slightly heavier than rice husks, and the mixed rice of wind-selected brown rice and unhulled paddy is sent to a paddy brown rice sorter. The rice is supplied to the rice lifter 15 from the drain 9 and the mixed rice conobear 14 which form the supply path of the rice lifter 15 for mixed paddy and brown rice connected to the rice lifter 15, and is lifted by the rice lifter 15 and discharged. The mixed rice is supplied from the pipe 16 to a mixed rice adjustment tank 17 provided on the side of the charging hopper 2.

(Refer to Fig. 7) A fulcrum shaft 2 provided by fixing the upper side of the mixed rice adjustment tank 17 to the side surface of the filling hopper 2
1, and a spring 24 is attached to the support rod 18 on the opposite side.
The biasing force of the spring 24 can be adjusted with an adjustment nut 20, and the adjustment tank 17 and the control valve 26 are connected by a linked mechanism 25 made of a wire, a flexible elastic rod, etc. It is configured so that the vertical operation caused by the increase or decrease in the storage amount of the paddy/brown rice mixed rice that is connected and conveyed is transmitted to the control valve 26 to control the amount of raw material paddy supplied to the dehulling chamber.

At the discharge port of the mixed rice adjustment tank 17, a regulation valve 22 for regulating the discharge amount of mixed paddy/brown rice and a first adjustment collar 23 are connected by a iron 58 so that the opening degree can be freely adjusted. is in contact with. A leveling plate 28 that prevents drifting of the supplied paddy/brown rice mixture is pivotally attached to the equalizer 27, and is urged in the closing direction by a spring 29.
The rice mixed with paddy and brown rice is rectified by the leveling plate 28 to have a uniform thickness, and is supplied from the supply section 52 to the sorting board 32. In addition, equalizer 2
A switching valve 30 for changing the flow path for supplying to each stage of the sorting board or for supplying to the car board is provided near the discharge section 7.

(See Figures 3 and 4) The paddy/brown rice sorting machine 60 is
The upper parts of the support rods 33 and 34 are pivotally supported on the swing frame 31, and
A sorting plate 32 is cut out from the swinging frame 31, and its force application point is connected to the crankshaft 35 of the eccentric rotation mechanism by a connecting rod 36, so that the swinging direction of the sorting plate 32 is parallel to the de-walling roll 6.7. The swing frame 31 is mounted so as to be perpendicular to the shafts 4 and 5 and swing up and down diagonally according to the swing angle, and the angle adjustment screw 38 for adjusting the inclination angle of the sorting board 32 is connected to the angle adjustment arm 37. The mixed paddy/brown rice supplied from the supply section 52 to the sorting board 32 is connected to the support rod 34 by screwing into the support rod 34 (see Fig. 2). Due to the vertical sorting action, brown rice with high specific gravity and low friction coefficient is concentrated on the shaking side.
A brown rice basin R is formed, a hulled rice basin P with a small specific gravity and a large friction coefficient is concentrated on the opposite side, and a mixed rice basin M of unhulled brown rice is formed in the middle thereof, while the draining channel 55 direction of the discharge section is formed. The unhulled rice, unhulled brown rice mixed rice,
The unhulled rice is divided into brown rice, and the unhulled rice is transferred to the unhulled rice from the unhulled rice return flow path consisting of the unhulled rice flow path 39 and the unhulled rice lifting machine 42.
52 is returned to the hopper 2 of the floating machine 59, and the paddy/brown rice mixture is transferred to the paddy/brown rice mixed rice flow gutter 40 and the mixed rice flow lower gutter 50.
The paddy and brown rice are returned to the supply path of the rice lifter 15 for mixed rice and re-sorted, and the brown rice flows from the brown rice flow gutter 41 to the rice lifter 44 for brown rice and is lifted by the rice lifter 44. The brown rice is configured to be discharged from the machine through a discharge flow pipe 46.

Next, the structure of the discharge device of the present invention will be described with reference to embodiments. Reference numeral 45 in FIGS. 3 and 6 is an upper discharge port whose outer peripheral wall is shaped like a semicircular arc. The flow pipe of the discharge port 45 is branched into branches in two directions, and a switching valve 48 is installed at the branched portion. With Riru,
A flow tube forming a storage chamber 47 is provided on the side connected to the outer peripheral wall, and a brown rice discharge flow tube 46 for discharging brown rice to the outside of the machine is provided inside.
An opening/closing valve 49 is provided at the end of the flow tube forming the storage chamber 47. It is connected to the supply route for machine 15.

Since the configuration is as described above, the switching valve 48 at the branch part of the discharge port 45 is opened on the storage chamber 47 side, and the storage chamber 47 side is opened.
In the state where the connection to the supply path of the rice lifter 15 for mixed paddy and brown rice is shut off by the on-off valve 49 provided at the end of the flow pipe, the screen is sorted and separated on the sorting board at the initial stage of operation (see Figure 2). The grains flowing while moving are placed in each sorting basin R1M on the sorting board,
Until P is formed normally, the unsorted rice is also mixed with unhulled rice that enters the brown rice basin R due to the shaking action, and these incompletely sorted grains F are transferred to the brown rice lifting machine. 44 and is lifted to the discharge port 45 by the rice lifting machine 44,
Due to the semicircular arc shape of the discharge port 45 and centrifugal action due to the rice lifting speed, the incompletely sorted grains are preferentially stored! Completely sorted brown rice is stored in the storage chamber 47, and is discharged when the sorting condition on the sorting board becomes good. The brown rice automatically overflows into the brown rice discharge pipe 46 and is discharged outside the machine.

Then, before the end of the operation, the incompletely sorted grains stored in the storage chamber 47 are returned to the supply path of the fried rice m15 for mixed paddy and brown rice by operating the on-off valve 48 of the emergency exit 61, and are re-sorted.
At the same time, the flow path change switching valve 48 is operated to block the flow of grains into the storage chamber 47, and the brown rice is discharged outside the machine.

When the grains stored in the storage chamber 47 are completely discharged and the amount of grains to be supplied to the sorting board becomes insufficient, the switching valve 30 provided in the equalizer 27 is operated to feed only to a single sorting board. When the paddy is re-weighed after several cycles of cyclic sorting and there is no more paddy mixed in, the brown rice is taken out of the machine by operating the re-marking changeover valve 48 and the operation is completed.

As described above, according to the discharge device of the present invention, the incompletely sorted grains discharged at the initial stage of operation are stored in the storage chamber, and the brown rice that has been well sorted and discharged is overflowed from the storage chamber into the brown rice discharge flow pipe. Is it possible to let it flow and discharge it outside the machine, which is not possible with conventional equipment? il
The switching operation of the mixing rice flow gutter l\ for the east of incompletely sorted grains in the early stage of operation, which was avoided, is omitted, and the incompletely sorted grains can be transferred to the rice lifter for mixed paddy and brown rice after the supply of raw material paddy is completed. Therefore, the mixed rice conveyor and the rice lifter for mixed paddy/brown rice do not need particularly large capacities, and the mixed rice adjustment tank also transmits fluctuations in the storage amount to the control valve and reacts accordingly. It only needs enough volume to cover the fluctuations in the storage amount up to a certain point, making the volume of the mixed rice adjustment tank significantly smaller than that of conventional equipment, and significantly reducing the lifting height of the rice lifting machine for mixed paddy and brown rice. This has the great effect of reducing the size of the entire device as much as possible, streamlining costs such as drawing costs, empty space for installation, packaging and transportation costs, etc. Roughly speaking, miniaturizing the device makes it easier to monitor, or to reduce costs in the early stages of operation. It has the effect of ensuring efficient hulling work is carried out reliably and smoothly, with functional improvements such as reducing hectic operations and focusing on checking the dehulling rate and skin misalignment.

Note that the return flow gutter is not limited to this embodiment; for example, depending on the capacity of the device, a storage tank may be installed separately in the flow pipe section of the storage chamber, or the rice may be returned to the mixed rice adjustment tank from the upper discharge port. In some cases.
