Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an automatic sorting adjustment device for a huller, and is applied to the field of a huller, which is an agricultural machine.

[Conventional technology]

Conventionally, JP-A-59-49853 discloses that a sensor for detecting the flow rate of unhulled rice is provided in the unhulled rice return path from the pot-hole type rotary sorting cylinder. This automatically adjusts the hulling roll.

[Problem that the invention attempts to solve]

The present invention can control the sorting length of the pot-and-hole rotary sorting cylinder according to the quantity to achieve high sorting accuracy and efficiently sort, and automatically adjusts to improve sorting performance. It is intended to be provided so that it can be carried out in a suitable manner.

[Means to solve the problem]

To this end, the present invention constructs a brown rice receiving trough B and a supply conveyor trough C inside the pot-hole type rotary sorting cylinder A, and also connects the end side opening of the rotary sorting cylinder A to a detachable part D.
In the hulling machine installed and constructed so as to communicate with the roll tank 2 side of the supply conveyor gutter C
A first supply port 4 is formed in the lower part of one end side C, and a second supply port 4 is formed in the middle of the supply conveyor gutter C.
The supply port 5 is equipped with a valve 6 that can be opened and closed freely, and the rotary sorting cylinder A is equipped with a flow rate detection sensor 7 that can detect the amount of paddy and control the valve 6. .

According to the present invention, the rotary sorting cylinder A
Since it is possible to adjust the length of the sorting process within the chamber, it is possible to carry out highly accurate sorting.

〔Example〕

Next, the embodiment shown in FIGS. 1 to 5 will be described.

Figure 2 shows a partially cutaway side view of the huller, with a mixed rice spiral conveyor 8 in the long wind sorting box E;
A finished rice spiral conveyor 9, a suction dust remover 10, a mixed rice thrower 11, a finished rice thrower 12, etc. are installed, and the removing part D connected to the upper end of the wind sorting box E is automatically installed at the bottom. Both roll release rollers 14, 14 are located below the roll tank 2 equipped with the shutter 13.
It is constructed in the same way as the conventional structure.

In addition, rotary sorting cylinders Aa each having a large number of pot holes 1 on the circumferential surface and open at both ends are installed at the top and bottom of the inside of the case 15 which is connected to the upper side of the other end of the wind sorting box E. The rotary sorting cylinders A and a are constructed so as to be freely rotatable by rotary wheels 16 that are in contact with the lower sides of both ends thereof, and the upper rotary sorting cylinder A has a supply conveyor gutter C and a spiral conveyor 17 and 18 respectively installed therein. Erect the brown rice catcher B in parallel,
The upper end side of the mixed rice thrower 11 is connected to the supply tank 19 which communicates with the starting end side of the supply conveyor gutter C, and the outer lower part of the terminal end side of the rotary sorting cylinder A is connected to the gutter 2.
The brown rice receiving gutter B is connected to the roll tank 2 through the gutter 21, and the terminal side of the brown rice receiving gutter B is connected to the lower rotary sorting cylinder a through the gutter 21.
The sorted rice is sent to the mixed rice spiral conveyor 8 and finished rice spiral conveyor 9, and is constructed in the same manner as the conventional structure.

A first supply port 4 is provided at the lower part of the supply conveyor gutter C, which extends to the inside of the starting end side of the rotary sorting cylinder A, near the terminal end C, and is equipped with a first supply valve 3 that can be opened and closed freely, and is operated by a cylinder 22. A second supply port 5 is formed below the middle of the supply conveyor gutter C so as to face the middle of the rotary sorting cylinder A, and a second supply valve 6 operated by a cylinder 23 is fully opened and closed. The gutter 20 is installed so that it can be opened half-open, and the gutter 20 is equipped with a flow rate detection sensor that can detect the amount of paddy falling from the terminal end side of the rotary sorting cylinder A and open and close the valves 3 and 6 as described above. -7, but an in-body flow valve 24 that can open and close the first supply valve 4 may also be provided near the bottom of the second supply port 5.

Therefore, during work, the mixed rice that has been removed from the removal section D and selected in the selection box E is thrown up into the supply tank 19 by the mixed rice thrower 11, and is also transferred to the supply conveyor gutter C by the spiral conveyor 17. However, in a state where the flow rate detection sensor 7 detects the amount of paddy as a normal state, as shown in FIGS. 1 and 2, the first supply The second supply port 5 is opened when the port 4 is fully open.
is half open, and the mixed rice supplied in large quantities from the first supply port 4 and in small quantities from the second supply port 5 is properly sorted while reaching the terminal side B.

Further, during high-efficiency work, if both supply ports 4 and 5 are fully opened as shown in FIG. 4 based on the detection by the sensor 7, the supply amount can be increased and high-efficiency work can be performed.

Furthermore, when a small quantity of mixed rice is supplied, the first supply port 4 is closed and the second supply port 5 is fully opened, as shown in FIG. Fig. 6 shows another example diagram, in which a rotary sorting cylinder 25 is provided between the terminal side roll of the rotary sorting cylinder A and the roll tank 2 to allow brown rice to leak out. and the lower drop gutter 26 is installed so as to communicate with the side of the mixed rice spiral conveyor 8,
Brown rice is sorted out from the paddy sent from the rotary sorting cylinder A to the roll tank 2 to prevent brown rice from being supplied to the removal section D.

Further, FIGS. 7 to 9 show still another example, in which a holder 29 of a brush 28 that can come into contact with the inner surface of the cylinder is slidably attached to a support shaft 27 that is installed parallel to the inside of the rotary sorting cylinder A. The brush 28 is installed so that it can be pushed and pulled by the operation rod 30, and is normally placed close to the starting end side A so as not to get in the way. By hooking the operating rod 30 to the holder 29 and moving the brush 28 from the start end side A to the end side B, it is possible to remove the residue inside the barrel and also remove the stuff clogged in the pot hole 1. This means that cleaning can be carried out without having to tilt the entire machine and run it idle, as was the case in the past.

Note that the sensor 7 is connected to the automatic shutter 1.
It is also possible to have a configuration in which they are linked so that they can be operated.

[Effect of idea]

The present invention has the following effects.

Since the supply state can be changed by adjusting the opening degree of the second supply port 5 according to the amount, the length of the sorting stroke in the cylinder can be suitably adjusted to maintain proper sorting accuracy.
