Description

  The present invention relates to a shell feeding hopper used by being attached to various devices, and a shell surface cleaner to which the hopper is attached.

  When scallops, oysters, etc. are cultivated by suspending them in the sea, algae or underwater trash adheres to the surface of the shells of shells while they are suspended in the sea. These deposits are scraped off by a shell cleaner. In the conventional shell surface cleaner, the shell supplied in the side V-shaped moving passage is transferred from the inlet side to the outlet side of the moving passage by the rotation of the shell transferring body, and both of the moving passages are transferred during the transfer. The cleaning tool arranged on the outer side is rotated, and the nail of the cleaning tool is brought into contact with the shell surface to scrape off deposits adhering to the shell surface (see Patent Document 1). There is a hopper for supplying shellfish on the entrance side of the moving passage. As shown in FIGS. 10, 11 (a) and 11 (b), the conventional hopper A includes a pocket B and a loading guide C. The pocket B is open at the top and front, and the peripheral wall D and the bottom E are narrowed downward. A shell guide passage F formed obliquely downward and surrounded by the peripheral wall D and the bottom E is formed, and the shell S introduced into the shell guide passage F is automatically turned vertically, and the shell below the hopper diagonally. It is guided in the movement path of the surface cleaner. The throwing guide C has an arc shape and is attached to the outer periphery of the upper opening of the pocket B so that the shell S is reliably guided into the pocket B.

Japanese Utility Model Publication No. 52-43676.

The conventional shell surface cleaner hopper has the following problems.
(1) Since the outer peripheral edge of the shell rolls (moves) on the bottom E of the pocket B as shown in FIG. 11 (b), the tip H of the feed piece G rotating the shell transporter is When the shell S in B is sent (supplied) to the movement path of the shell surface cleaner, the shell S is pushed by the tip H of the feeding piece G of the shell surface cleaner and pressed against the bottom E of the pocket B. For this reason, the outer peripheral edge of the shell S may be strongly pressed by the lower part J of the bottom E at the lower part of the guide passage F of the pocket B where the width becomes narrower and chipped. If the outer peripheral edge of the shell S is missing, the shell size may be reduced, the appearance may deteriorate, the shell class may be lowered, the commercial value may be reduced, and the price may be reduced.
(2) Since the outer peripheral edge of the shell S is uneven, the shell S that rolls down (moves) on the bottom D of the shell guide passage F of the pocket B does not roll (moves) smoothly by jumping or the like. In some cases, the shell S may not be smoothly delivered from the end of the shell guide passage F into the movement passage of the shell surface cleaner.

  The hopper of the present application is provided with a pocket having a shell guide passage on the bottom and inside of the peripheral wall, the shell guide passage is narrowed on the outlet side, and the shell put into the shell guide passage is automatically oriented vertically. It rolls down in the guide passage. When opening the shell from the bottom of the shell guide passage to the outer peripheral edge of the shell guide passage, the shell in the shell guide passage is fed into the shell surface cleaner with the shell piece cleaner. The pushing of the shell to the bottom of the shell guiding passage by the feeding piece is eased. The pocket is open at the top so that shells can be easily introduced from the outside, and the front is opened at the front so that the shells in the shell guide passage can be fed out easily by the feeding piece of the shell surface cleaner. In addition, a throwing guide projecting outward is provided on the outer periphery of the upper opening of the pocket so that the thrown shell is reliably guided into the guide passage of the pocket.

  The shell surface cleaner with a hopper of the present application is a shell surface in which the shell put into the hopper is supplied into the moving passage and the dirt on the surface of the shell is removed while the shell is transferred in the moving passage. It is a cleaner, and the hopper is provided in front of the moving passage.

The hopper of the present application and the hopper of the shell surface cleaner have the following effects because the opening from which the outer peripheral edge of the inserted shell is projected is formed at the bottom of the pocket.
(1) When the shell in the shell guide passage is sent to the shell passage cleaner's moving passage by the feeding piece of the shell surface cleaner, even if a strong downward force is applied to the shell, Since the outer peripheral edge of the shell protrudes downward from the opening at the bottom of the shell guide passage of the pocket, the force applied to the shell is buffered, the outer peripheral edge of the shell is not lost, and the product value of the shell is prevented from being lowered. be able to.
(2) Even if the outer periphery of the shell is uneven, the outer periphery of the shell protrudes downward from the opening at the bottom of the shell guide passage of the pocket, so the shell rolling down on the bottom The shell does not jump at the lower end of the guide passage, and the shell is smoothly fed into the movement passage of the shell surface cleaner.

  The hopper of the present application and the hopper of the shell surface cleaner have the pockets at the upper and front openings, and the outlet side of the shell guide passage in the pocket is narrowed. Thus, there is an effect that the inside of the shell guiding passage smoothly rolls and is smoothly sent out into the moving passage of the shell surface cleaner.

  Since the hopper of the present application and the hopper of the shell surface cleaner are provided with a feeding guide on the outer periphery of the upper opening of the pocket, the shell to be thrown in is surely guided into the pocket by the feeding guide and falls out of the hopper. There is almost nothing, and there is no damage or death of shells due to falling. In addition, since it is only necessary to put the shell into the insertion guide outside the pocket, there is no need to put the hand into which the shell is inserted into the pocket, and the hand, fingertip, etc. can be used as the feeding piece of the shell transporter of the shell surface cleaner. There is an effect that there is no injury due to contact or entrainment, and it is safe and preferable in terms of labor management.

(Embodiment 1)

A hopper 1 shown in FIG. 1 includes a pocket 2 having upper and front openings, and a loading guide 3 provided outside an upper opening 2 a of the pocket 2. Since the pocket 2 has an upper opening, the feed piece 20 of the shell transporter 14 enters from the upper opening 2a of the pocket 2 as shown in FIGS. The shell S placed in the guide passage 10 is rolled downward while being pressed downward, and can be sent (supplied) to the moving passage 13 of the shell surface cleaner.

  As shown in FIGS. 1 to 3, the pocket 2 is formed by bending a plate material, welding a combination of plate materials, or bonding them. The pocket 2 is formed with an upper and front opening guide passage 10 surrounded by a peripheral wall 2b and a bottom 2c. As shown in FIGS. 3A and 3B, the peripheral wall 2b and the bottom 2c are formed so as to be inclined obliquely downward in the forward direction and in the downward direction. Therefore, the guide passage 10 is formed to be narrowed downward as shown in the figure, and the shells that are thrown in are automatically vertically oriented and smoothly roll in the guide passage 10, and the shells that are diagonally forward and downward from the guide passage 10. The guide is smoothly guided into the movement path 13 of the surface cleaner. The plate material used for the pocket 2 can be made of any material such as metal or hard resin. The pocket 2 can be made by resin molding or other methods instead of processing a plate material.

  As shown in FIGS. 1 to 3, an opening 5 is formed in the lower portion 4 of the bottom 2 c of the pocket 2 so that the front (moving passage side) gradually becomes wider. The opening 5 has such a width that the outer peripheral edge of the shell S protrudes downward. In addition, in order to prevent the side walls of the opening 5 from being pushed open by shells, the side walls are connected to each other, reinforcing materials are attached to the side walls, the side walls are thickened, Ribs can also be formed on the walls. As shown in FIG. 3 (b), the shape of the opening 5 can be any width, length, shape, etc. as long as the outer peripheral edge of the shell S protrudes below the pocket 2. In either case, even if the shell is inserted into the shell guide passage 10 in the pocket 2 in either the vertical or horizontal direction, it automatically falls vertically and is guided to the moving passage diagonally forward and downward. It is.

  As shown in FIGS. 1 to 3, attachment portions 6 are formed on both outer sides of the upper opening 2 a of the pocket 2. The attachment part 6 is for attaching the hopper 1 to a shell surface cleaner. The mounting portion 6 shown in FIGS. 1 and 2 is formed in a downward U-shape by bending a plate material outward. For example, as shown in FIGS. 4 and 5, the attachment portion 6 can be attached to the entrance side of the moving passage 13 by fixing the hopper 1 to the mount 11 of the shell surface cleaner. If the attachment part 6 is a shape and structure which can be attached to a shell surface cleaner, it can be set as the shape and structure other than shown in a figure.

  As shown in FIGS. 1 to 3, the charging guide 3 has an arcuate shape, and the center opening edge 8 is placed on the outer peripheral edge of the upper opening 2 a of the pocket 2 and protrudes to the outside. It is fixed with welding or adhesive. As shown in FIG. 2, the upper outer peripheral edge of the charging guide 3 is folded outward to form a rib 7 so that it will not be cut even if a hand or fingertip comes into contact with the shell when the shell is inserted. Similarly to the pocket 2, the charging guide 3 can be made of any material such as metal or hard resin. The input guide 3 can be molded with the resin integrally with the pocket 2. The size, shape, and the like of the charging guide 3 are not limited to those shown in the figure, and may be any size, shape, and the like.

(Shell surface cleaner with hopper)
An example of a shell surface cleaner with a hopper of the present invention will be described with reference to FIGS. The shell surface cleaner of FIG. 4 includes support legs 12 at four corners of a square frame-shaped gantry 11, a moving path 13 is provided inside the gantry 11, and a shell transporter 14 is provided above the moving path 13. Cleaning tools 15 a and 15 b are provided on the left and right sides of the moving passage 13. The hopper 1 of the present invention is attached to the entrance 50 side of the moving passage 13 as shown in FIGS. The shell surface cleaner is not limited to the one shown in FIGS. 4 and 5 and can be of any configuration.

  As shown in FIG. 6 (a), the movement path 13 has a large number of bar members 17 facing the left and right columns, arranged side by side with a slight shift in position, and directed from the upper end to the lower end of the bar member 17. Inclined inward to form a side-shaped V-shaped space between the left and right bar members 17, and this space is used as the movement passage 13. Each bar 17 in the left and right rows has its upper end fixed to the gantry 11 by welding or other means, and the lower ends are abutted against each other with a gap in the traveling direction of the moving passage 13 so that the lower ends do not contact each other. 77 is formed so that the shell S can move on the bottom surface 77 without dropping off, and the dust scraped off from the surface of the shell S falls from the gap of the bar 17 and is collected in the moving passage 13. There is no way. Further, as shown in FIG. 6A, the bar members 17 in the left column and the right column are arranged with an interval in the arrangement direction, and a space between the adjacent bar members 17 is used as the opening 18. . The opening 18 is wider than the width of the claw 19 of the cleaning tool 15 (FIG. 4) so that the claw 19 can protrude into the moving passage 13 from the opening 18. The upper ends of the bars 17 in the left and right rows are left separated (opened), and the moving passage 13 is an upper surface opening.

  As shown in FIGS. 4 and 5, the hopper 1 is arranged above the entrance 50 side of the moving passage 13 by mounting the mounting portion 6 on the mount 11. In this case, the hopper 1 is attached so that the charging guide 3 protrudes above the gantry 11 so that the shell can be easily loaded into the hopper 1. The shell S introduced into the hopper 1 falls vertically and falls under its own weight and is guided by the moving path obliquely forward and downward, and the outer peripheral edge of the shell S projects outward from the opening 5 of the hopper 1.

  As shown in FIGS. 4 and 5, the shell transfer body 14 has a feed piece 20 attached to an outer peripheral surface of a rotary traveling body 21 such as an endless belt conveyor or a chain with a spacing in the rotation direction. For example, a hard rubber plate or a resin plate is suitable for the feed piece 20, and the shape of the feed piece 20 is made to match the V shape of the moving passage 13 and the width of the tip portion is narrowed. In this case, the tip of the feed piece 20 enters the hopper 1 while rotating as shown in FIG. When the rotary piece 21 is rotated in the direction of arrow B in FIG. 4 by the motor 33 in FIG. 4, the feed piece 20 pushes the shell that has entered the hopper 1 and is put into the hopper 1 downward, and feeds it into the movement path 13. It rotates and sends out to the exit 60 side of the movement path 13. The shellfish is transferred through the moving passage 13 while rotating. As shown in FIG. 4, the feed piece 20 is attached so that the tip is inclined rearward in the rotational direction, so that the shells in the moving passage 13 can be easily fed out.

  As shown in FIG. 4, in the cleaning tools 15 a and 15 b, a large number of scrapers 80 are attached to a single rotating shaft 22 at intervals in the axial direction of the rotating shaft 22. As shown in FIG. 7, the scraper 80 is obtained by attaching an L-shaped metal claw 19 to the outer peripheral surface of a disc-like mounting plate 23. The mounting plate 23 is integrally formed in a disc shape by a material having elasticity such as rubber, resin, etc., a shaft mounting hole 24 is opened at the center thereof, and openings 25 are opened at regular intervals toward the outer periphery. Elasticity is imparted to the connecting portions 26 therebetween, and ring-shaped outer ring portions 27 are formed on the outer sides of the connecting portions 26. An L-shaped metal claw 19 is attached to the outer peripheral surface of the outer ring portion 27.

Adhesives or other means can be used to attach the claw 19. The claw 19 is bent in a square shape in the rotation direction (arrow direction) of the scraper 80 in FIG. 8 so that it can easily come into contact with the surface of the shell during rotation and can easily scrape off the surface of the shell.

  The scraper 80 is not limited to that shown in FIGS. 7 and 8 and may be as shown in FIG. The scraper 80 shown in FIG. 9 has a large number of metal coil springs 81 attached to the outer peripheral surface of the disc-shaped mounting board 23 at a uniform interval, and a chip-like scraping piece 82 attached to the tip of each coil spring 81. Is. The mounting board 23 is made of any member such as metal, resin, or rubber formed into a disk shape, and a shaft mounting hole 24 is opened at the center. Although it is desirable from the viewpoint of scraping that the coil spring 81 is tightly wound to increase its elasticity, any coil spring can be used. The scraping piece 82 is not limited to a chip shape, and various shapes and structures such as a plate shape, a protrusion shape, and a claw shape can be used.

  As shown in FIG. 4, the scraper 80 shown in FIGS. 7 to 9 is attached to the rotary shaft 22 in a line at a predetermined interval. In this case, the spacer 28 of FIG. 4 is interposed between the adjacent scrapers 80, and a predetermined interval is provided between the scrapers 80.

  As described above, the cleaning tools 15a and 15b having a large number of scrapers 80 attached to the rotary shaft 22 are arranged along the movement path 13 on the left and right outer sides of the movement path 13, and in addition, the cleaning tools 15a and 15b. The intervals between the rotary shafts 22 are set to be equal from the inlet 50 side to the outlet 60 side so that the tips of the claws 19 of the respective cleaning tools 15a and 15b protrude into the moving passage 13 from the opening 18 of the moving passage 13. is there. Further, one of the two cleaning tools 15a and 15b is arranged in a downward slope from the inlet 50 side to the outlet 60 side of the moving passage 13 as shown in FIGS. The book is arranged in an upward slope from the entrance 50 side to the exit 60 side of the moving passage 13. By disposing in such a manner, one of the cleaning tools comes into contact with the upper part of the shell and the outlet 60 side comes into contact with the lower part of the shell, and the other cleaning tool comes into the lower part of the shell with the inlet 50 side. The nail | claw 19 of the scraping tool 80 contacts the surface of the whole shell (from the bulging center part to the thin outer periphery part), and scrapes off the dirt on the whole surface. I can do it.

  The two cleaning tools 15a and 15b can be inclined in the same direction up and down. Moreover, it can also arrange | position horizontally, without making it incline. Further, the interval between the two cleaning tools 15a and 15b may be such that the inlet 50 side is wide and the outlet 60 side is narrow, or conversely, the inlet 50 side is narrow and the outlet 60 side is wide. it can.

  As shown in FIG. 4, rotation transmission bodies 31a and 31b are attached to one end of each of the rotary shafts 22 of the cleaning tools 15a and 15b. As the rotation transmission body 31, tires having various structures such as a hollow tire filled with air or a solid rod tire are used. It seems that both tires contact each other at their outer peripheral surfaces and rub against each other sufficiently to transmit the rotation of one tire to the other tire.

  As shown in FIG. 4, a universal joint 32 is attached to an end portion of the rotary shaft 22 opposite to the end portion to which the rotation transmission body 31 b is attached. The shaft 22 and a transmission shaft 34 attached horizontally to the gantry 11 are rotatably connected. As shown in FIGS. 4 and 5, a receiving pulley 35 is attached to the transmission shaft 34, and a belt 37 is stretched between the receiving pulley 35 and a driving pulley 36 of a driving source (motor) 38. This rotation is transmitted to the drive pulley 36 -the receiving pulley 35 -the transmission shaft 34 -the rotation shaft 22 so that the rotation shaft 22 rotates. The motor 38 may be replaced with another drive source such as an engine instead of the motor.

  When the motor 38 is rotated, the rotation of the motor 38 is transmitted to the driving pulley 36-the receiving pulley 35-the transmission shaft 34-the rotating shaft 22 via the belt 37 as described above, and the rotating shaft 22 rotates, and the cleaning tool 15b. Rotates. When the cleaning tool 15b rotates, the rotation transmission body 31b rotates, and the rotation transmission body 31a on the cleaning tool 15a side in contact with the rotation transmission body 31b also rotates in the same direction (both downward with respect to the movement path). In accordance with the rotation of the rotation transmitting body 31a, the rotating shaft 22 of the cleaning tool 15a also rotates, and the cleaning tool 15a also rotates. In the shell surface cleaner of the present invention, when the motor 38 is rotated, the cleaning tools 15a and 15b are both rotated downward with respect to the moving passage 13, and are pulled down to the shells in the moving passage 13 (moving passage 13). Force in the bottom direction) can be actuated and stabilized in the movement passage 13 to scrape off the shell deposits.

  The drive pulley 36 attached to the motor 38, the receiving pulley 35 of the cleaning tool, and the belt 37 can be replaced with sprockets and chains.

  In the above, only one cleaning tool 15b is directly rotated by the motor 38. However, the rotation shaft 22 on the cleaning tool 15a side is also provided with a pulley, and both the rotation shafts 22 are driven by a belt. You may make it rotate by 38.

  The mechanism for rotating the two cleaning tools 15a and 15b is not limited to the rotation transmission bodies 31a and 31b using the tire, and may be any other mechanism. Therefore, for example, a pulley for rotation transmission is attached to the end of the rotary shaft 22 of each of the cleaning tools 15a and 15b on the inlet 50 side, and the two cleaning tools 15a and 15b are rotated by hanging a transmission belt. Is also possible. Further, the rotation transmission bodies 31a and 31b are not limited to tires, and arbitrary ones such as gears, leaf springs, and drums can be used.
