In this way, the objects to be sorted are sorted while being subjected to the synergistic action of the swinging sorting action and the wind sorting action by the sorting wind, and the first thing (fine granules), the second thing, the dust, The first product is sifted and sorted by the grain sieve 21 and then dropped into the receiving gutter of the first transfer spiral 14 to be collected and taken out of the machine. The second product is the second product From the transfer helix 15 it is fried by the second fryer and returned to the handling chamber 8 for reprocessing. Then, the dust is sucked and sucked out by the suction dust exhaust fan 16 and discharged out of the apparatus.
Is also drawn into the suction / dust fan 16 from the shelf and discharged out of the machine.

The feed chain 11 is stretched so as to be rotatable and driven between the drive sprocket 38 and the stretched wheels 39, 39, and has a chain rail 40, a chain support frame 41, a mesh In this configuration, the frame is integrally supported by the holding frame 42 and the like. The feed chain 11 configured as described above is configured to swing and open and close using a fulcrum shaft 43 provided in a lower position and parallel to the handle cylinder shaft 7a as a fulcrum.

A drive shaft 44 for rotating the drive sprocket 38 is provided with a meshing pawl clutch 45 for intermittently rotating drive force to the feed chain. The meshing pawl clutch 45 includes a driving-side pawl clutch body 45a and a driven-side pawl clutch body 45b, and is configured to be capable of being fitted and disengaged.

The driving sprocket 38 includes a fulcrum shaft 43
A shaft 47 fixed to a rotating frame 46 that rotates around a fulcrum.
It is erected in. The fulcrum shaft 43 is located substantially on the same line (Y) as the meshing opposing portion of the meshing pawl clutch 45 and is set therebelow, so that the engagement / disengaging action of the meshing pawl clutch when opening and closing the feed chain. Is performed smoothly.

The fulcrum shaft 43 is connected to a transmission cable on the machine body side.
A support member 49 mounted and supported on the switch 48. The lock on the fuselage after the feed chain is closed is configured to be fastened and fixed to the fuselage side via knob bolts 50, 50 at the front side and the rear side of the chain rail 40.

The chain support frame 41 and the rotating frame
The chain 46 is an integral structure, and the chain supporting frame 41 and the chain 40 are detachably connected and held by mounting bolts 51 or the like. With such a configuration that can be divided into two parts, the dimensional accuracy of the chain rail mounting part and the rotation fulcrum part can be made accurate,

Then, the feed chain and the rail can be easily removed completely.

Another embodiment relating to opening and closing of the chain (FIGS. 11 and 12) will be described. The front ends of link arms 53 and 54 which are parallel to the front and rear are pivotally supported at two front and rear positions of the chain 40. Front link arm 53
Is mounted on the base shaft so as to swing back and forth with the drive shaft 44 of the drive sprocket 38 as a rotation fulcrum, and a rear link arm 54 is provided with the base end mounted on the side of the machine body. Axis 5
The entire feed chain is swingably displaced in the front-rear and up-down directions by swinging in the front-rear direction with the pivot point 5.

There has been a configuration in which the entire feed chain is rotated at one point on the front side (ie, around the drive sprocket shaft 44). However, since this is supported at one point, the strength of the fulcrum needs to be increased. In addition, when it is opened, it rises in a state of crossing the handling port, which is not only unstable, but also causes a problem that the maintenance property is deteriorated. According to such another embodiment of the present invention, since the link arm is supported at two points by the front and rear link arms, stability can be ensured and the feed chain can be opened with minimum movement.

After the feed chain is closed, the locking device 56 is closed.
Thereby, it can be securely fixed to the fuselage side. In the figure,
57 is a tension roller and 58 is a tension arm. The operation (swinging) range of the link arms 53 and 54 is made large so that the link arm swings below a horizontal line passing through the rotation axis of the base end, so that the feed chain can be reduced accordingly. It can be widely opened.
