  Based on the drawings, the elevator has an upper pulley 4 mounted on the upper part of the lifting cylinder 3 with a pulley shaft 20 and a lower pulley 5 mounted on the lower part with a pulley shaft 21. In the meantime, a flat belt 2 having buckets 1 arranged at regular intervals on the outer peripheral surface can be stretched and rotated. The elevating cylinder 3 is in the form of a rectangular plane that is long in the front-rear rotation direction of the bucket 1 and the belt 2, and forms a supply port 22 for supplying the grain to the lower front side, and a hopper port of the supply hopper 23 on the outside. 24 can be set. A discharge port 25 is formed on the rear side of the upper end of the lifting cylinder 3, and the grains of the cereals are discharged from the discharge port 25 in each bucket 1 in the lifting cylinder 3, and a grain dryer, Grain can be supplied to a grinder, a rice mill, etc.

  Each bucket 1 can be attached along the rotation outer peripheral surface of the belt 2 and cerealed by rotation. This flat belt 2 constitutes an endless belt-like belt 2 by connecting both ends of one long belt 2 with a connecting tool 8 at a joint. The joint portion of the belt 2 is formed with bent end edges 6 and 7 that are bent at right angles toward the outer peripheral side at both ends, and connected with a connecting tool 8, and a scraper parag 9 is attached to the bent end edges 6 and 7. It is formed and rotated close to the bottom surface of the lifting cylinder 3. A bottom plate 17 having a semi-cylindrical shape is provided around the pulley shaft 21 at the bottom of the elevating cylinder 3, and the tip edge 11 of the scraper parag 9 approaches or slidably contacts with the inner peripheral surface of the bottom plate 17 as a bottom surface 18. Rotate. The bent end edges 7 formed at the joints on both ends of the belt 2 are connected by being tightened by inserting the connecting tool 8 with the back face facing. The connector 8 includes a bolt 27, a nut 28, and the like, and is inserted into connecting holes 29 and 30 formed in the bent end edges 6 and 7 and the sandwiching plate 10 to be overlapped on both front and rear surfaces, and is fastened and fixed.

  The clamping plate 10 forms a pressing edge 26 that is pressed along the outer peripheral surface portion of the belt 2 in an angle form, and is superposed along the front and rear outer surfaces of the bent end edges 6, 7, and these bent end edges 6. , 7 so as to sandwich.

  Here, the belt 2 having the bucket 1 attached to the outer peripheral surface is stretched over the elevating cylinder 3 between the upper pulley 4 and the lower pulley 4, and the both-end joints of the belt 2 are bent at a right angle toward the outer peripheral side and bent. The edge portions 6 and 7 are formed, and the back surface portions of the bent edge portions 6 and 7 are contact-polymerized, and are fastened and connected by a connecting tool 8 to form a scraper 9. It is set as the structure of the bucket belt of the elevator characterized by rotating close to the bottom face of the raising / lowering cylinder 3.

  The bucket belt 2 having the bucket 1 on the rotating outer peripheral surface is polymerized between the bent end edges 6 and 7 which are bent at right angles to the outer peripheral side, and the bent end edges 6 and 7 are in contact with each other. Since the overlapping portions are connected to each other by the connecting tool 8 and are configured to rotate endlessly, a part of the connecting tool 8 is exposed on the inner circumferential surface of the belt 2 and the lower pulleys 4, 5 The bent end edges 6 and 7 that are tightened and connected by the connecting tool 8 to make smooth rotation with less vibration without touching any rotating peripheral surface, etc. It rotates by approaching or slidably contacting the bottom surface of the elevating cylinder 3 and scraping it up so as not to produce residual grains on the bottom surface. The residual grain written out from the bottom surface portion is crushed by the subsequent bucket 1 and cerealed.

  Further, the bent end edges 6 and 7 of the belt 2 are clamped between the clamping plates 10 made of a hard plate, and are fastened and connected by a connector 8, and the leading edges 11 of the bent end edges 6 and 7 are The scraper plug 9 is formed so as to protrude longer than the leading edge of the sandwiching plate 10.

  As described above, when the bent end edges 6 and 7 are connected to each other by the connecting tool 8, the holding plate 10 is superposed on both outer side surfaces of the bent end edges 6 and 7, and the holding plate 10 is overlapped. The bent end edges 6 and 7 are protruded outward from the front end edge of the holding plate 10 so as to cause a whipping operation. For this reason, when the bent edge portions 6 and 7 are guided around the lower pulley 5 and rotate, the leading edge 11 protrudes long and rotates while moving close to or in sliding contact with the bottom surface of the lifting cylinder 3. Raise and clean so that there are no residual grains. In this embodiment, the tip edge 11 that is close to or slides and rotates near the bottom surface of the elevating cylinder 3 is formed of the material of the bent edge portions 6 and 7 that constitute the belt 2, so that the rotational resistance with respect to the bottom surface 8 can be reduced. This can reduce damage to the cereal kernels.

  Further, a scraper plate 12 made of a hard plate is interposed between the back surface portions of the bent edge portions 6 and 7, and is fastened and connected by a connecting tool 8, and the leading edge 13 of the scraper plate 12 is connected to the bent edge portion 6, The scrape parag 9 is formed so as to protrude outward from 7.

  The scraper plate 12 that sandwiches and connects the bent end edges 6 and 7 of the joint portions at both ends of the bucket belt 2 has a leading edge 13 protruding longer than the leading ends of the bent end edges 6 and 7, At the time of cereal rotation, it rotates by approaching or slidingly contacting the bottom surface of the lifting cylinder 3, scraping the remaining grains on this bottom surface, cleaning it, and transporting it with the subsequent bucket 1. The scraper plate 12 is made of a hard material, and the joint between the bent end edges 6 and 7 of the belt 2 is firmly fixed and connected to stabilize the mounting posture of the scraper plate 12. Since the scraper plate 12 is supported by protruding from the belt 2 through the bent end edges 6 and 7, the scraper plate 12 is supported by the belt 2 through the bent end edges 6 and 7. Allowing distortion swing in the rotation direction, the resistance between the bottom surface of the lifting cylinder 3 can be reduced, and the cereal grains are not damaged.

  Further, the bent end edges 6 and 7 of the belt 2 are clamped between the clamping plates 10 made of a hard plate, and are fastened and connected by a connector 8, and the leading edge 14 of the clamping plate 10 is connected to the bent edge part. The scraper plug 9 is formed so as to protrude longer than the tip edges of 6 and 7.

  At the time of cereal rotation, it rotates while approaching or slidably contacting the bottom surface of the lifting cylinder 3, and the rotation of the belt 2 rotates the clamping plate 10 that sandwiches the bent end edges 6, 7. Clean the grain. In addition, when the sandwiching plate 10 is long and protrudes on both the front and rear sides of the bent end edges 6 and 7, the rotating sandwich plate 10 is rotated at an interval of the front and rear bent end edges 6 and 7. Since the two-stage sweeping movement is performed by the leading edge 14, a smooth and unreasonable cleaning effect can be exhibited. In addition, since the base portions of these sandwiching plates 10 are fastened and fixed by the connecting tool 8 so as to sandwich the overlapped thickness interval between the bent end edges 6 and 7 of the belt 2, the leading edges 14 of both the sandwiching plates 10 are fixed. Independently rocking and distorting, it is less likely to clog the grain or the like in the space between the front and rear clamping plates 10, and the cerealing action is performed smoothly.

  Furthermore, the holding plate 10 or the scraper plate 12 is formed with an elongated hole 15 for inserting the connector 8 or an adjustment hole 16 having a different arrangement position, and the holding plate 10 or the scraper plate 12. The protrusion length position of is configured to be adjustable.

  An elongated hole 15 is formed in the connecting tool 8 insertion hole of the clamping plate 10 that clamps and attaches the bent edge portions 6 and 7 of the belt 2 or the scraper plate 12 that clamps and attaches between the bent edge portions 6 and 7. By tightening the clamp plate 10 and the bent edge portions 6 and 7 of the scraper plate 12 by forming (A) or forming an adjustment hole 16 having a different insertion position of the connector 8 (B), etc. The clamping position is moved along the elongated holes 15 or the mounting positions of the clamping plates 10 and the scraper plate 12 are changed to select the adjustment holes 16 to be mounted, whereby the clamping plates 10 and the scraper plates 12 are mounted. The position of the tip edges 13 and 14 of the cleparag relative to the bottom surface of the elevating cylinder 3 is adjusted according to the wear such as smooth and accurate cerealing and bottom cleaning.
