Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a stone removing device in a grain wind separator capable of selectively selecting grains by wind selection.

2. Description of the Related Art A conventional stone removal device, as shown in Japanese Utility Model Publication No. 58-89648, removes stones from below a swinging sorting plate.
A fan dedicated to removing stones began to blow air, and a fan exclusively for rocking (I7) (1) and (8) a complex and large structure was developed, which the invention attempts to solve. Problems The present invention provides a method for grain wind selection in which the suction air from the suction II dust machine is applied to the lower part of the grain supply-side falling port so that the wind speed can be adjusted. It is designed to remove stones, and automatically adjusts the sorting of stones in conjunction with the operation of the wind power or stone removal detection sensor, and has a compact and simple structure that ensures good results. The present invention is provided so that stone removal can be carried out suitably.

Means to Solve the Problem Therefore, in this Nagisa proposal, a gap between the grain extraction side, which is the suction and dust removal machine side, and the stone extraction side on the opposite side of the grain supply side and the falling port on the blade side. A selection valve is installed upright at the top, and the selection valve is linked and rotated so that its inclination can be changed by the wind force adjustment or the operation of a stone removal detection sensor.

Function: With this configuration, grains containing stones are all eluted from the falling port and are air-selected, and the sorting valve can effectively sort and separate the grains and stones. While automatically adjusting the sorting valve in conjunction with the operation of the detection sensor, it is possible to perform the sorting of stones with high accuracy.

Embodiment Next, an embodiment shown in the drawings will be described. In Fig. 1, a lead roller (6) for feeding is mounted on a shaft at the lower side of the supply hopper (5) so as to be fully rotatable.
6) Install the grain board (7) installed diagonally below so that the lower end side becomes the drop port (1) facing downward, and the drop port (1)
A selection valve (8), which can be rotated by a motor (Ml) to change the inclination, is installed on the lower side of the support shaft (8), and grains are placed on one side of the lower side of the drop opening (1). A sorting air passage (9) is installed obliquely on the extraction side (4), a grain extraction port (←0) is provided on the lower side of the sorting air passage (9), and a suction dust extractor (2) is provided on the upper side. The suction ports (2a) and t are connected to each other, and the suction ports (2a)
) is equipped with a wind force control valve C11) rotated by a motor (M2), and both motors (M l ) (M2
) It is connected to the q control box (12) and is installed so that when the wind force control valve (1°C) is operated, the selection valve (8) can also change the slope in conjunction with it, and it becomes the other side below the drop port (1). On the stone outlet side (7), a stone extraction trough 8) is completely diagonally installed below the lower side of the selection valve (8).

Fig. 2 shows another embodiment, which has a substantially similar structure to the previous embodiment as indicated by the same reference numerals, but a photoelectric stone removal detection sensor (4) is installed above the stone removal machine (18). The sensor (4) and the motor (Ml) are connected to the control box (12&) for related operation.

Therefore, in the case of the embodiment shown in FIG. 1, during work,
When the thoroughly mixed grains fall from the drop opening (1) while being fed out by the lead roller (6), the suction dust extractor (
The grains are sorted by the suction sorting wind flowing as shown by the arrow ←) in 2), and the grains are separated by the sorting valve (8) and flow toward the sorting air passage (9), so the grains are taken out and placed in the mouth. Arrow (
As shown in b), as the dust falls, the dust is sucked into the suction dust remover (2), while the stones, which are slightly heavier than the grains, are separated by the sorting valve (8) and fall to the stone remover OS> side. The person will fall as shown by the arrow (c).

In this state, depending on the condition of the grain, the wind force control valve 01) is rotated in the direction of the arrow to weaken the wind force, and the selection valve (8) is interlocked and rotated in the direction of the arrow. It is possible to prevent the grains from scattering on the stone increase side (η), and if the wind force control valve Q°C is turned in the direction of the arrow (E) to increase the wind force, the sorting valve (81 It will rotate in the hanging direction of the arrow in conjunction with this, and it will be possible to prevent stones from getting mixed in with the grain removal side (■).

In addition, in the other embodiments shown in Fig. 2, similar sorting is carried out, but a stone removal machine (IB)'e detects flowing stones etc. using a stone removal detection sensor (4) and removes many stones. Rotate the sorting valve (8) in the full arrow (e) direction until a small amount of grains flow in to remove it, or turn the sorting valve (8) in the direction of the arrow (e) until more than the specified amount of grains flow in. (8) can be rotated in the direction of the arrow ω.

Effects of the Invention As described above, the present invention allows the suction air from the suction dust extractor to be applied to the lower part of the falling port on the supply side of the grains, while separating the grains using the sorting valve, thereby making it possible to effectively remove stones. In addition, it is possible to adjust the inclination in conjunction with the wind force adjustment or the operation of the destoning detection sensor to ensure complete accuracy in sorting, making it possible to perform destoning with high precision. ff
It has the feature that it can be made compact and well structured, and can be suitably implemented.
