Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rice residue discharge device in a rotary sorting huller.

Generally, a rice huller is comprised of a huller, a sorting device, and a grain lifting device. There are various types of sorting devices, and among these, there is a rotary cylindrical type with a large number of recesses provided on the inner surface, and its basic structure is already known. This rotary sorting machine has a rotatable sorting tube with a number of recesses, which has a cross-sectional channel of a ■ or U shape inserted horizontally, and while rotating the sorting tube, mixes rice from one end of the tube. The material is supplied and allowed to flow gently in the axial direction through the sorting tube. During the flow, the mixed rice
As the sorting cylinder rotates, the rice tries to be scooped up, but the brown rice of the mixed rice gets stuck in the dents, and only the portion that gets into the dents is lifted upwards and falls in a parabola. , Since the above-mentioned receiving gutter is installed at the point where the rice falls, only the brown rice is received in the receiving gutter, and is carried out of the machine by the spuffle conveyor inside the receiving gutter, and the paddy and brown rice are separated. be.

By the way, the sorting performance of this sorting machine is greatly affected by the specific gravity of paddy/brown rice, the coefficient of friction, the rotational speed and inclination of the sorting cylinder, etc. Therefore, when designing a rotary sorter, trial and error is carried out in an attempt to make the overall size of the huller as compact as possible while increasing its throughput. the result,
Good results were obtained by keeping the sorting cylinder approximately horizontal. However, if the sorting tube is made almost horizontal, the receiving gutter must also be made parallel to it, and as a result, a large amount of grain remains in the sorting tube or in the receiving gutter when the hulling operation is interrupted or completed. You can't avoid doing that.

The present invention was devised in an attempt to solve this problem, and its object is to easily discharge the remaining grains to the outside of the machine using a simple device.

Embodiments of the present invention will be described below with reference to the attached drawings, in which Fig. 1 shows a cross section of the entire rice huller. Hulling part C on one side
is placed, and a rotary sorting machine (2) is placed side by side with the hulling section C to form the whole structure.

Wind sorting section B has 2 flavor conveyors 1, mixed rice conveyor 2,
Three brown rice conveyors are installed in each gutter. A suction port of a suction dust remover 4 provided at one end in the longitudinal direction of the wind sorting section B communicates with an intake port 6 provided at the other end in the longitudinal direction of the wind sorting section B. 2. In the - direction of 8, the sorting air is made to flow in the direction of the arrow shown by the broken line.

The huller A is equipped with a pair of deweighing rolls 9, a hopper 10 is installed above them, and below the deweighing rolls 9,
Flowing grain plates 11 are positioned on three sides of the mixed rice conveyor 2. The deweighing row /l/9 is driven by a motor M built in the wind selection section B via an appropriate transmission means.

On the machine side, a mixed rice thrower 12 and a brown rice slurry 13, which communicate with the mixed rice conveyor 2 and the brown rice conveyor 3, are provided.

The rotary sorting machine has two rotatable sorting tubes I and (2) suspended horizontally in a box-like cake 14 in two lower and lower stages.

These sorting tubes 1. The ItO axis direction is exactly perpendicular to the axis of the deweighing row/l/9 in the hulling section C.

These sorting tubes have a large number of hemispherical recesses 15 that can fit brown rice all over the entire inner circumference, making it possible to fit the sorting tube 1. Both ends of II are open.

A receiving trough 17 for receiving brown rice, which has a cross section of a ■-shaped cross section, is inserted into the inside of the sorting tubes L and ■ and is suspended horizontally. A conveyor 18 is housed in these receiving troughs 17.

In addition to the receiving gutter 17, a two-barrel scree conveyor 19 is arranged in parallel to the upper sorting tube 1. ”Sando Nuku IJ
, - One end of the mixed rice thrower 12 faces the hulling section C side of the conveyor 19.

The lower sorting tube ■ communicates with the terminal end of the receiving gutter 17 in the sorting tube I, and is designed to sort the brown rice grains sorted in the sorting tube 1.

Reference numeral 20 denotes a machine base having a wheel projecting/retracting mechanism for the rice huller A having the above structure, and a support shaft 21 is provided at approximately the middle of the machine base 20 in the front-rear direction, passing through both left and right sides.

As shown in FIG. 2, the arm 2 extends backward from this support shaft 21.

The operating rod 29 inside the machine body projects 1 inch outside the machine from a guide groove 80 formed vertically in the rear wall. The operating rod 29 is locked by a spring pawl 31 of a suitable mechanism.

When an operator pushes down the connecting rod 32 connecting the operating rods 28 and 29 with his/her weight, both operating rods 28 and 29 rotate around the support shaft 21, and the wheels 26 and 29 rotate accordingly.
, 27 protrude from below the body, and at that time, one operating rod 28 is locked by the spring claw 31.

In addition, in order to return the wheels 26 and 27 into the fuselage, use the connecting rod 82.
The operator can remove the spring claw 3] from the operating rod 28 while stepping on it.

Next, sorting cylinder 1. ■ At the bottom of the receiving gutter 17 (and the upper scree conveyor 19) provided in the interior, there is a drop port 33 that extends over almost the entire length, as shown in Figure 3, and the rice remaining in the drop port 33 is removed. A discharge switching valve 34 is provided so as to be openable and closable.

A lever 85 is fixed to one end of the support shaft 35 of the switching valve 34, and when the lever 8 rotates, the switching valve 84 opens and closes. The illustrated switching valve 34 is provided in the receiving gutter 17 in the upper sorting cylinder I, and 36 is the upper body nut in the sorting cylinder 1, -
A support shaft of a switching valve (not shown) provided on the conveyor 19,
Reference numeral 87 indicates a support shaft of a switching valve (not shown) provided in the receiving gutter 17 in the lower sorting cylinder I.
6.87 have the same shape as the illustrated switching valve 84 and support shaft 85.

The center part of the bell crank 38 is fixed to one end of the support shaft 86 of the upper trunk screw conveyor 19, and the center part of the lever 39 is fixed to one end of the support shaft 37 of the lower sorting cylinder 11. Levers 85, 89 and bell crank 3
8 are rotatably connected to each other by links 40 and 41, and furthermore, one end of the lever 39 is connected to the operating rod 28 via a link 42 so as to be V-shaped.

Since it has the following configuration, the usage of the rotary sorting and hulling machine is as follows: When paddy is fed to the hopper 10 (this example is a small and portable one, the paddy bags are removed). The mixed rice of paddy and brown rice is deweighed by the huller C, and is then wind-selected in the wind sorting part B and falls onto the mixed rice conveyor 2, where it is mixed rice. It is jumped up by the Nulower 12 into the supply tank 12', and is supplied from the tank 12' into the upper body Nucle conveyor 19, and is carried to the right end of the sorting cylinder 1 in the upper part of FIG. It is transferred and supplied to the inner surface of the sorting cylinder 1 from there. Sorting tube 1
As it is rotating, the mixed rice is piled up on the inside of the sorting tube I and is about to be scooped up, but the brown rice is stuck in the recess 15 and is lifted upwards compared to the paddy, while drawing a parabola. , falls into the receiving gutter 17.

Since the paddy does not fit into the recess 15, it falls onto the inner surface of the sorting tube I again while drawing a small parabola at a low position. While repeating this state, the paddy is returned to the hopper 10 from the left end of the sorting tube I.

On the other hand, brown rice, etc. that has fallen into the receiving gutter 17 of the sorting tube I is fed by the Nuclei conveyor 18 in the receiving gutter 17 to the sorting tube ■ located below the left end of the sorting tube I, with some paddy mixed in. The remaining brown rice is again subjected to the same sorting action as in the upper sorting tube I in the lower sorting tube ■, and is refined into oil.

The paddy (some of which is brown rice) that has not been scooped out in the sorting cylinder M is again supplied onto the mixed rice conveyor 2. on the other hand,
The brown rice scooped up by the sorting cylinder ■ falls onto the brown rice conveyor 3 while being subjected to the wind sorting action, and is carried out of the machine by the brown rice thrower 13.

When the amount of paddy supplied decreases and the sorting begins to deteriorate,
I have to finish the work, but at this time, the sorting tube! ,
A large amount of paddy and brown rice remains in It and receiving trough 17. On the other hand, when transporting the rotary sorting rice huller, when the worker steps on the connecting rod 82 downward, the wheel portion 27 protrudes, making it easy to transport, but since the rear of the machine is raised, The aircraft tilted, and the sorting tube, which was in a nearly horizontal position, also tilted.
The remaining rice will fall off. In the present invention, in particular, when the connecting rod 82 is depressed, the lever 85, 89, bell crank 88, each link 40, 41.42. The remaining rice in these drains will also fall out.

At this time, since the motor M is in a human state, the upper and lower sorting tubes 1. All of the remaining rice in I is accumulated in the popper 10, and unsorted remaining rice is redundantly taken out of the machine. However, the shutter in the hopper 1o (which does not measure water) is closed and does not communicate with the -C deweighing row IV,
Brown rice Nurowa 18 is kept in a circulating state.

In summary, the present invention provides a rotary sorting huller equipped with a rotatable sorting tube suspended horizontally in a horizontal manner, in which a receiving gutter is provided in the sorting tube substantially parallel to the axial direction of the sorting tube; This is a residual rice discharging device for a rotary sorting huller in which the bottom of the rice grain is opened and closed in conjunction with the tilting movement of the sorting tube, so that it has the following effects.

(1) The sorting tube that is hung horizontally improves the sorting performance of paddy and brown rice, but on the other hand, a large amount of rice remains in the sorting tube after the work is finished, so it is difficult to sort. By tilting the cylinder, you can take out the remaining rice, and
Since the bottom of the receiving gutter can be opened and closed, residual rice in the gutter can be removed and completely taken out of the machine.

(2) Since the opening and closing of the bottom of the receiving trough and the tilting of the sorting tube are linked, it is possible to confirm whether the bottom of the receiving trough is blocked and prevent incorrect operation of the huller.
