The front and rear movable bodies 3 and 4 are adjacent to each other in front and rear and left and right with both vertical bars 3b and 4b intertwined with each other and alternately in parallel, and both horizontal bars 3c and 4c also intertwined with each other. The vertical bars 3b, 4b and the horizontal bars 3c, 4c are formed so as to secure an appropriate interval S through which the sorting object can pass.

[0007] The front movable body 3 has a horizontal rod 3a portion which is removably supported by an opening-shaped front support portion 1d rearward on the rear side of the excavation portion 1a of the bucket 1, and The entire movable body 3 can swing up and down with the support portion as a fulcrum. Similarly, the rear movable body 4
The horizontal rod 4a is supported by an opening-shaped rear support portion 1e so as to be able to be inserted and removed from the front toward the front in front of the rear surface portion 1b of the bucket 1, and the movable body 4 The whole can swing up and down. The upper holding portion 1f of the rear supporting portion 1e is detachably attached to and fixed to the rear surface portion 1b with a fixing tool 1g such as a bolt and a nut, so that the front and rear movable bodies 3 and 4 can be attached and detached. The vertical movement of the movable portion 3 is not prevented.

The drive mechanism system 5 is configured such that an intermediate portion of an operating rod 5a is pivotally supported by a pivot 5b on the left and right inner surfaces 1h below the movable portion 2 in the bucket 1 so as to be capable of leverage.
A front rod 5c is mounted between the front ends, and the front rod 5c and each vertical bar 4b immediately above the movable body 4 on the rear side are connected integrally with each other by a connecting rod 5d. In addition, a rear rod 5e is suspended between the left and right operating rods 5a, and the rear rod 5e and the front movable body 3
Each of the vertical bars 3b immediately above is connected integrally with each other by a connecting rod 5d. Then, the rear surface 1b of the bucket 1
A connecting shaft 5g is provided between the rear end portions 5f of the left and right operating rods 5a penetrating rearward from the hole portion 1i, and a movable arm 5h pivotally mounted on the connecting shaft 5g is provided by a hydraulic motor. 5i
Of the hydraulic motor 5i
Is converted into a lever motion of the left and right operating rods 5a, so that the front movable body 3 and the rear movable body 4 swing equally in the vertical direction opposite to each other. Also, bucket 1
Left and right operating rods 5a penetrating rearward from the hole 1i of the rear surface portion 1b, a connecting shaft 5g, a movable arm 5h, and a hydraulic motor 5i.
Are covered with a cover 6.

Thus, the pair of movable bodies 3 and 4 receive the driving force of the hydraulic motor 5i and swing equally in mutually opposite vertical directions while maintaining the vertical parallel relation, and swing back and forth. In addition, the state of waving up and down is repeated (see FIGS. 4A, 4B, and 4C). The sorting object on the screen deck 2a is repeatedly hit from below, and the sorting object is vertically and horizontally adjacent to each vertical bar 3b. , 4b, the space S between the horizontal bars 3c, 4c
From below.

FIGS. 5 to 9 illustrate an installation type as another embodiment of the sorting apparatus of the present invention. In an opening 9a of a hopper 9 installed on a conveyor 8 in a base 7, a movable part 10 composed of a pair of movable bodies 11 and 12 is disposed to be inclined forward, and the movable part 10
And a pair of movable bodies 1 on the outside of the side 9b of the hopper 9.
A drive mechanism system 13 for guiding and driving the motors 1 and 12 in mutually opposite vertical directions and driving the motor is provided.

The movable section 10 includes a screen deck 10 tilted forward.
a is formed of a pair of movable bodies 11 and 12, and the movable bodies 11 and 12 are arranged in a state in which the two vertical bars 11a and 12a are alternately arranged in parallel, and each of the vertical bars 11a and 12a adjacent to the left and right. It is formed so as to secure an appropriate interval S through which the sorting object can pass. The vertical bar 11a of one movable body 11 is
A series of front and rear rods 13g in 3 and a vertical bar of the other movable body 12
The reference numeral 12a is connected to the front and rear connecting rods 13h of the drive mechanism system 13 so as to be able to move in parallel in mutually opposite vertical directions.

The driving mechanism system 13 includes a front rotating shaft 13a and a rear rotating shaft 13b at right and left side portions 9b below the movable portion 10 in the hopper 9.
A pair of front and rear front arm portions 13c and 13d are respectively mounted on both ends of the front rotating shaft 13a penetrating outside of the left and right side portions 9b, and similarly, A pair of front and rear front arm portions 13e and 13f are respectively mounted on both ends of the rear rotation shaft 13b penetrating outside the portion 9b. Then, between the left and right front arm portions 13c and between the front arm portions 13e, a series of rods 13g are passed through the long holes 9c of the left and right side portions 9b.
Each of the front and rear series bars 13g and the vertical bars 11a immediately above one of the movable bodies 11 are connected integrally with each other by connecting bars 13i. Also, between the left and right rear arm portions 13d and the rear arm portion 13f, the left and right side portions 9b are provided.
The other connecting rods 13h are each mounted on the shaft via the long hole 9d,
The front and rear other connecting rods 13h and the vertical bars 12a immediately above the other movable body 12 are integrally connected by a connecting rod 13i. A front operating arm 13j is provided at both ends of the front rotating shaft 13a, and a rear operating arm 13k is provided at both ends of the rear rotating shaft 13b.
