るものである。 That is, the powder overfeed prevention scraper S shown in FIGS.
When passing through the discharge port D opened at the bottom of the trough, the waste is not discharged from the discharge port D, but is deposited on the top surfaces of the conveyor chain C, blades W, etc., and attempts to pass through the discharge port D. The discharge gate G is in sliding contact with the upper surfaces of the chain C and the blades W, etc., in order to wipe off some of the powder and granular material from the upper surfaces of the chain C and the blades W, etc. on the discharge port D, and cause them to fall and be discharged. In conjunction with the opening/closing operation of the trough, it is rotated between the downward rotating position where it makes sliding contact and the upward rotating position which is further above the upper surface of the transported powder and granular material in the trough.

介してスクレーパ取付軸S′に伝動している。 The interlocking mechanism between the discharge gate G and the scraper S consists of one arm L1 of a two-arm lever member L rotatably supported by a mounting shaft B on a frame F extending outward from the side wall of the trough T. The free end is freely inserted into the channel-shaped guide member R provided in the discharge gate G, and the free end of the other arm L2 is connected to the free end of the crank lever member L' via the connecting rod A. The base end of the crank lever member L' is fixed to an intermediate support shaft, and power is transmitted to the scraper mounting shaft S' via a gear.

粒体の全量が排出口を通過することができる。 Therefore, when the cylinder device P is actuated to move the discharge gate G in the direction of the arrow A in FIG. 3, the gate G closes the discharge port D, and one arm L1 of the two-arm lever member Move in the direction of the arrow
The connecting rod A is moved in the direction of the arrow C, and the scraper mounting shaft S' is rotated to move the lower end of the scraper S above the upper surface of the granular material in the trough, so that the granular material is transported by the conveyor chain C. The entire amount of powder and granular material to be conveyed can pass through the discharge port without being obstructed by the scraper S.

なる欠点を有している。 However, since the conventional interlocking mechanism between the scraper and the discharge gate as shown in FIGS. 3 and 4 described above is a motion transmission mechanism using a plurality of links, it is necessary to ensure a wide space occupied by the mutual motion of the links. In addition, the movement mechanism is complicated and the number of parts is large.

防止機能が低下する欠点を有している。 In addition, the cleaning plate explained in the book title ``Chain Conveyor'' mentioned above rotates downward and upward in conjunction with the opening and closing operation of the discharge gate G' shown in Fig. 5, and when rotating downward. It has the same purpose as the conventional example shown in FIGS. 3 and 4 in that it prevents overfeeding of powder and granules on the discharge port, but the interlocking mechanism between the discharge gate G' and the cleaning plate E is different from the discharge gate. A pair of actuating rods that stand apart from each other in the opening/closing movement direction of the gate.
The free end of the rotating lever E' of the cleaning plate E is interposed between H 1 and H 2 , and when the discharge gate G' moves in the direction of closing the discharge port D', the free end of the rotating lever E' When the cleaning plate E is pushed by one of the operating rods H1 of the pair of operating rods and rotates upward from the upper surface of the powder material being conveyed, and the discharge gate G' moves in the direction of opening the discharge port, the pair of operating rods The free end of the rotary lever E' is caused to rotate in the opposite direction by the operating rod H2 on the other side of the rod, so that the lower edge of the cleaning plate E is moved downward to a position where it slides into contact with the upper surface of the conveyor chain C'. Therefore, at the downward movement position of the cleaning plate E,
The free end of the rotating lever E' is in a floating state between the pair of actuating rods H 1 and H 2 with respect to the direction of movement of the conveyed powder and granules, and when the cleaning plate E receives the conveyance pressure of the powder and granules, it moves in the conveyance direction. This has the drawback that the overfeed prevention function of the cleaning plate E is deteriorated because it is possible for the cleaning plate E to escape.

る。Function When the discharge gate moves forward in the direction of closing the discharge port,
The roller attached to the bracket moves forward along the scraper rotation support shaft, forcibly rotates the thread cut into the end of the scraper rotation support shaft, rotates the support shaft, and raises the scraper. When the discharge gate moves backward in the discharge port opening direction, the roller attached to the bracket moves back along the scraper rotation shaft, and the scraper rotation shaft is attached to the thread guided by the roller. It then rotates in the opposite direction and rotates downward to a position where the lower edge of the scraper can slide into contact with the upper surface of the conveyor chain.

送されることはない。 Therefore, when the discharge gate is in the discharge port closing position, the lower edge of the scraper is pulled up above the upper surface of the conveyed powder and granules, allowing smooth passage of the entire amount of the conveyed powder and granules, and the discharge gate is closed. When the discharge port is in the open position, the lower edge of the scraper is pulled down to a position where it makes sliding contact with the upper surface of the conveyor chain and blades, and the scraper accumulates on the upper surface of the chain and blades and tries to pass over the discharge port. The powder and granules are scraped off from the upper surface of the chain and blades, etc., and dropped from the discharge port, so that the entire amount of the transported powder and granule material is released from the feed and discharge port and is passed over the discharge port. There isn't.

目１１が施されている。 Further, on the discharge port 6 in the trough 5, a rotating shaft 9 is provided with a scraper 8 for preventing overfeeding of powder and granules.
is mounted on a shaft across the trough 5, and the lower edge of the scraper 8 is provided with a strip-shaped cut 11 so as to be able to conform to the irregularities of the upper surface of a conveyor chain 10 with blades for transporting powder and granular materials.

動駆動させられる螺条１２が刻設されている。 One end of the scraper rotation support shaft 9 forms a rotation support shaft end portion 9' extending protruding from the trough side wall,
The end portion 9' of the pivot shaft is provided with a thread 12 which is forcibly driven to rotate by a guide roller 3 attached to the bracket 2 of the discharge gate.

凸設されている。 The thread 12 rotates the scraper rotation support shaft 9 in the scraper upward rotation direction when the bracket 2 moves in the discharge gate closing direction, and rotates the scraper rotation support shaft 9 in the scraper upward rotation direction when the bracket 2 moves in the discharge gate opening direction. It is provided so as to be inclined in the direction of rotation in the downward rotation direction.

全量が排出口上を通過して搬送される。 Therefore, when the discharge gate is moved forward in the discharge port closing direction from the discharge port open state shown in FIGS. 1 and 2, the guide roller 3 of the bracket 2 moves forward along the scraper rotation shaft end 9'. The thread 12 of the scraper rotation support shaft end 9' rotates while being forcibly guided by the guide roller 3, rotates the scraper 8 upward, and the lower edge of the scraper 8 is rotated to remove the powder and granules in the trough. Since the scraper is positioned above the top surface of the scraper, the top surface of the transported powder does not come into contact with the lower edge of the scraper.
The entire amount passes over the discharge port and is conveyed.

送は防止されるものである。 Further, when the discharge gate 1 moves backward in the direction of opening the discharge port 6, the scraper rotation support shaft 9 rotates and rotates the lower edge of the scraper 8 downward to a position where it comes into sliding contact with the upper surface of the conveyor chain 10. Therefore, the powder and granules that have accumulated on the conveyor chain 10 and are about to be over-feeded over the discharge port 6 are scraped off by the scraper 8 and fall from the discharge port 6, thereby preventing over-feeding of the powder and granules. It is something that will be done.

持するとよい。 Note that the guide roller 3 forcibly guides the thread 12 in rotation only when the scraper 8 is rotated upward, the downward rotation of the scraper 8 is performed by the scraper 8's own weight, and the guide roller 3 is rotated by its own weight. It serves to prevent sudden downward rotation of the scraper. However, in order to reliably rotate the scraper 8 without swinging, it is preferable to provide a pair of guide rollers to sandwich the thread 12.

る。Effects of the invention In the present invention, a thread is carved directly on the end of the rotational shaft of the scraper, and a guide roller for forcibly guiding the rotation of the thread is attached to a bracket erected at the discharge gate. Since the opening and closing movement of the discharge gate directly rotates the rotation shaft of the scraper without going through a link mechanism, the interlocking mechanism between the discharge gate and the scraper has an extremely simple structure, and the space occupied by the interlocking mechanism is also significantly reduced. The upper and lower rotational positions of the scraper can be reliably maintained by the abutment movement between the thread and the guide roller. Even if the edge slides into contact with the top surface of the conveyor chain, it does not rotate upward due to the sliding friction with the top surface of the conveyor chain, so the powder and granules accumulated on the conveyor chain are reliably wiped away. This can prevent overfeeding of powder and granular materials.

的効果は著大である。 Furthermore, since the thread 12 of the scraper rotation support shaft was forcibly rotated by the guide roller, the thread 12
The forced rotation is carried out easily by the rolling contact of the guide rollers, there is little resistance, the rotation operation of the scraper is smooth, there is no wear on the thread 12, and durability is improved. Since the thread 12 and the guide roller 3 are in contact with each other so that they can be separated, it is much easier to install and center the thread and the guide roller than in the case of threaded engagement. The effect is significant.
