  TECHNICAL FIELD The present invention relates to a belt type elevator for grains, beans, and the like, and in particular, grain such as rice seeds, waste rice, brown rice or white rice is raised to a grain sorting device or the like with a protruding piece attached to the belt type elevator. The present invention relates to a structure of a projecting piece in a belt type elevator.

  Granular agricultural products such as cereals and beans are subjected to various treatment processes in the process of distribution from the production area to the consumption area, and various apparatuses have been proposed for transferring granular agricultural products in the treatment process. However, even though many of these devices are suitable for transferring large amounts of processing, many of them are too large for transferring small amounts of granular materials.

  For example, brown rice milled with a rice huller or white rice milled with a rice milling machine contains immature grains with a small particle size, and the grain surface is subject to friction and grinding action due to rice hulling. It is inevitable that a part of the crushed or deformed. For this reason, conventionally, it has been common to use a grain sorting device that removes waste grains by grain sorting of brown rice or polished rice. At that time, it was necessary to raise the grain.

  Such a cerealing operation is a heavy burden for small-scale farmers. Therefore, the cerealing apparatus is widely used in various fields as an agricultural machine. Also, in general, brown rice or white rice is sorted by a rice sorter and re-sorted after being taken out as waste grains, and the grains are classified according to use. A grain sorter is also being developed for use. And in this grain sorting device, it has been performed that a grain raising machine for feeding the grain to be sorted is also provided.

  As this type of technology, the applicant has filed a patent application (Patent Document 1 (Japanese Patent Laid-Open No. 2009-95732)) related to a mini-grader with a built-in elevator, and related patents (Patent Document 2 ( Japanese Patent Application Laid-Open No. 2009-96602)), and in connection with this, a product is manufactured and sold as “Chibi Mate” (registered trademark owned by the present patent applicant) (Non-patent Document 1). ing.

In the “elevator, a belt of a bucket conveyor is an upper flat pulley and The portion between the sub-pulleys (range indicated by L) is held in a straight line along the opening direction of the outlet, so the position where the grain in the bucket starts to be thrown out is the same position as the conventional elevator (S position), but when the bucket rotated around the upper pulley reaches the straight portion, the speed at the tip of the bucket decreases, so that most of the grain in the bucket moves in the straight portion. It is thrown along the direction (opening direction of the outlet), which makes it possible to throw off almost all the grain in the bucket at the position A, so that the grain can be thrown stably. It can be put out. "

  Furthermore, Patent Document 5 (Japanese Patent Laid-Open No. 2000-218233) states that “grains such as rice grains are immediately divided into sized grains having a desired particle size according to various qualities, grades or uses and other waste grains.

  The problem to be solved by the present invention is applied to a lifting / lowering unit that lifts and loads a grain to be sorted of a grain sorting device disclosed in Patent Document 1 (Japanese Patent Laid-Open No. 2009-95732) developed by the present applicant. The belt type lifting device, the grain lifting device disclosed in Patent Document 2 (Japanese Patent Laid-Open No. 2009-96602), or the technology applied to the product as disclosed in Non-Patent Document 1 is further improved, When transporting granular materials, the belt-type lifting device used in Patent Document 1, Patent Document 2, or Non-Patent Document 1 developed by the present applicant, without using a bucket or the like as in the conventional large-sized device. It will be improved and a belt type elevator with high transport capability will be completed while being a small and thin device using a small motor that is excellent in productivity and can be applied to relatively small farmers.

  That is, the belt type lifting device used in Patent Document 1, Patent Document 2, or Non-Patent Document 1 developed by the present applicant itself is endless between the driving and driven pulleys 100 and 101 as shown in FIG. The conveyor belt 103 is suspended, and the grains are raised by the protruding pieces 104 formed on the conveyor belt 103.

  When the conveyor belt and the protruding piece 104 are configured as separate parts and the protruding piece 104 is fixed to the conveying belt 103, the smaller the number of protruding pieces 104, the higher the productivity by reducing the number of assembled parts. It is also advantageous for cost reduction. When the protrusion 104 is fixed to the conveyor belt 103 as a separate part, the protrusion 104 fixed to the conveyor belt 103 is generally formed into an L shape having a mounting piece by pressing a metal thin plate. Here, since the conveyor belt 103 to which the protruding piece 104 is attached is suspended between the driving and driven pulleys 100 and 101, the conveying belt of the driving and driven pulleys 100 and 101 has an arc shape. Since the mounting piece 104 has a flat plate shape, both ends of the flat mounting piece easily lift from the conveyor belt 103 in the driving and driven pulleys 100 and 101, and therefore, it is necessary to make the mounting piece as short as possible. is there. However, when the fixing part of the attachment piece to the conveyor belt 103 is one place, the projecting piece 104 rotates around the fixing part, which not only adversely affects the cerealing ability but also collides with other components. In order to cause a failure, it is necessary to position the projecting piece 104 at least at two places and prevent it from rotating with respect to the conveyor belt 103.

  The present invention has been made in view of the above problems, and the length of the mounting piece for fixing the projecting piece to the transport belt is formed as short as possible, and the projecting piece is reliably prevented from rotating around the transport belt. It is an object of the present invention to obtain a structure of a projecting piece in a belt type elevator that can be fixed.

  The structure of the protrusion in the belt type elevator according to claim 1 of the present invention is such that a driving pulley is disposed at one end portion of a conveying device casing formed by a casing portion and an outer lid portion, and a driven pulley is disposed at the other end portion. An endless transport belt is suspended between the drive pulley and the driven pulley, and is disposed in the transport path space so as to be rotationally driven by a drive motor, and a plurality of protrusions that transport the granular material to the transport belt. A belt type elevator for forming a piece, wherein the protruding piece is bent into an L shape having an attachment piece fixed to a conveyance belt and a conveyance piece for conveying the granular material, and the conveyance piece is conveyed to the attachment piece A screwing portion for fixing to the belt and a rotation prevention portion for the conveyor belt are formed, and the screwing portion and the rotation prevention portion are formed at intervals in the length direction of the mounting piece. To do.

  The structure of the protrusion in the belt type elevator according to claim 2 of the present invention is such that the anti-rotation portion is constituted by a pointed claw piece bent from the front end portion in the length direction of the mounting piece, and the claw piece is transported by the conveyor. It is characterized in that it is bitten into the belt to prevent the protrusion from rotating.

  The structure of the projecting piece in the belt type elevator according to claim 3 of the present invention is such that the width w of the mounting piece is substantially the same as the width w1 of the conveyor belt, and the length b of the mounting piece including the claw piece; The relationship of the width w of the mounting piece is characterized by b ≦ w.

  According to the present invention, if the projecting piece is configured as a separate part, it is possible to use an existing transport belt without forming a dedicated belt such as integrally forming the projecting piece on the transport belt, and the manufacturing cost can be reduced. Become. Furthermore, when attaching another projecting piece to the conveyor belt, a screwing portion and a pointed claw piece located at the leading edge of the attachment piece are bent to the attachment piece, and the claw piece is attached to the conveyor belt. By using the anti-rotation portion by biting into the anti-rotation portion, the anti-rotation device prevents the protrusion from rotating relative to the conveyor belt, and the length of the attachment piece can be made as short as possible.

It is a disassembled perspective view of the belt type elevator of the Example of this invention. FIG. 2A is a front view, and FIG. 2B is a side view. It is a disassembled perspective view which shows the attachment state of a protrusion piece same as the above. It is sectional drawing which shows the attachment state of a protrusion piece same as the above. It is a use state figure of a belt type elevator. It is another use condition figure of a belt type elevator same as the above. It is another use condition figure of a belt type elevator same as the above. It is a front view of the belt type elevator which shows a prior art example same as the above.

  The whole structure of a granular material conveyance apparatus and conveyance mechanism in this invention are demonstrated using drawing. Hereinafter, in the description of the overall configuration of the transport device of the present invention, the transport mechanism, and the description of the embodiments, the granular material to be transported is limited to grains, but other granular agricultural products and other granular materials are described. Of course, the present invention is widely applicable.

  FIG. 1 is an exploded perspective view of a belt-type elevator in which the belt-type elevator according to the present invention is embodied as a specific example, and an object to be conveyed is realized as grains of granular agricultural products. According to this embodiment, from the appearance of the device shown in the drawing, at first glance, it resembles the configuration of the grain lifting device described in Patent Document 2 (Japanese Patent Laid-Open No. 2009-96602) already disclosed by the present applicant. May seem to be. However, the present invention pays attention to the relationship between the protruding piece and the cerealing ability that has not been realized in the device described in Patent Document 2 or the device of the invention implemented in the device described in Non-Patent Document 1. As a result of obtaining a reasonable number of protruding pieces, there is a great difference between the two in that the structure is obtained. Hereinafter, the present invention will be described based on the differences between the two.

  The belt type elevator 1 according to the embodiment of the present invention, as shown in FIG. 1, is a conveyance formed from a cerealing part 10 that cereals grains as a conveyance granular material, a casing part 30, and an outer lid part 50. It is comprised from the apparatus housing | casing 40, the drive motor 70 which drives the cerealing part 10, the supply part 52 and the sending part 90 of a conveyance grain.

  The granular material transfer device housing 40 has a flat and vertically long rectangular parallelepiped shape by the housing portion 30 and the outer lid portion 50. The conveyance device housing 40 of the belt type elevator 1 according to the embodiment of the present invention forms a substantially rectangular parallelepiped space in the conveyance device housing 40 by the housing portion 30 and the outer lid portion 50. The cereal portion 10 is arranged in the rectangular parallelepiped space. The cerealing unit 10 has a conveying belt 14 suspended on a driving pulley 12 disposed at a lower portion of a conveying device casing 40 and a driven pulley 13 disposed on an upper portion, and an outer peripheral surface 14a of the conveying belt 14 with a predetermined interval ( It is comprised by several protrusion piece 20,20,20 ... arrange | positioned by a).

  Thus, by arranging the endless transport belt 14 in the upright flat and vertically long rectangular parallelepiped transport device casing 40, an endless transport path space is provided around the endless transport belt 14. 60 is formed (indicated by the circulating arrows around the endless conveyor belt 14 in FIG. 2A). Further, the endless transport belt 14 has an endless transport path space 60 by forming and arranging a plurality of projecting pieces 20, 20, 20... On the outer peripheral surface 14 a at a predetermined interval (a). Is divided into a plurality of transport sections, the endless transport belt 14 is rotated at a high speed, and the grains are beaten and transported by the high speed rotation of the projecting pieces 20 formed on the outer peripheral surface 14a. is there.

  In the embodiment of the present invention, the casing unit 30 constituting the conveying device casing 40 is configured as a casing surrounding the conveying belt 14 of the cerealing unit 10, and the cerealing side of the endless conveying belt 14. On the left side in FIG. 1 or FIG. 2A, a guide wall 37 is provided along the inner side surface (belt back side surface) 14b of the conveyor belt 14, and the conveyor configured in the conveyor housing 40 is provided. Battering due to high-speed rotation of the conveyor belt 14 is suppressed on the cerealing side of the path 60 (left side in FIG. 1 or FIG. 2A). Here, the cerealing path side is an expression for the end of the endless transport belt 14 rotating clockwise in FIG. 2A so that the left outer side of the endless transport belt 14 contributes to the cerealing. .

  In addition, an arcuate guide wall 38 that surrounds the lower outer periphery of the drive pulley 12 is provided at the lower portion of the housing portion 30 so as to communicate with the conveyance path 60, and the guide wall 38 is elongated in the conveyance direction. A shading mesh 39 is formed, and the guide wall 38 forms a grain supply region 31 that surrounds the periphery of the conveyor belt 14 suspended on the drive pulley 12. The shape surrounding the periphery of the conveyor belt 14 is not limited to the shape of the arcuate guide wall 38, and it is sufficient that the grains supplied by the rotation of the conveyor belt 14 are efficiently swirled. .

  The front surface side of the housing unit 30 is closed by the outer lid unit 50 to form the device housing 40. A grain input hopper 53 is provided on the lower front surface of the outer lid portion 50, and a grain dropping port 54 of the charging hopper 53 communicates with the grain supply region 31 and also has a grain dropping port. 54 may exhibit a guide shape biased in the rotational direction of the drive pulley 12 so that the grain put into the feeding hopper 53 flows from the grain supply region 31 to the transport path 60 without any delay.

  In the upper part of the device housing 40, a sending unit 90 is provided for sending the transported grains from the device housing 40. The delivery unit 90 includes a cover body 32 that covers the open end of the upper portion of the apparatus housing 40 and a bellows tube 33 that communicates with the cover body 32. In the state shown in FIG. 1, the cover body 32 covered on the upper open end of the device housing 40 is covered so as to send the conveyed grains to the side opposite to the charging hopper 53 (right side in FIG. 1). However, the cover 32 may be placed on the opposite side, that is, on the same side as the charging hopper 53 (left side in FIG. 1) so that the delivery side of the cover body 32 faces (the specific structure is not shown, but an example of its use is shown in FIG. 7).

  When the projecting piece 20 is formed as a separate part and the projecting piece 20 is attached to the conveyor belt 14, not only is it subject to dimensional constraints with the conveyor belt 14, but also the impact on the conveyor belt 14 due to impact when conveying the cereal. Therefore, a strong mounting structure is required so that the protruding piece 20 does not rotate. That is, as shown in FIGS. 3 and 4, when the projecting piece 20 is formed as a separate part, the projecting piece 20 is mounted to fix the metal thin plate to the conveyor belt 14 by pressing or the like in terms of strength and processability. The piece 21 and the grain etc. are integrally formed into an L-shape having a conveying piece 22 for conveying the cereal. Here, since the conveyance belt 14 to which the projecting piece 20 is attached has a structure suspended between the driving and driven pulleys 12 and 13, the conveying belt 14 at the driving and driven pulleys 12 and 13 is arcuate, If the mounting piece 21 has a flat plate shape and the length b of the mounting piece 21 is long, both ends of the mounting piece 21 are lifted from the conveyor belt 14 in the driving and driven pulleys 12 and 13 and the grains just enter the gap. In addition, the attachment of the attachment piece 21 becomes unstable. For this reason, as shown in FIG. 3, the width w of the mounting piece 21 is formed to be substantially the same width as the width w <b> 1 of the conveyor belt 14, but the length b of the mounting piece 21 is the width of the mounting piece 21. Narrower than w. That is, the protruding piece 20 is formed so that the length b of the mounting piece 21 ≦ the width w of the mounting piece 21≈the width w1 of the endless belt. However, in one place where the attachment piece 21 is fixed to the conveyor belt 14, the protruding piece 20 rotates around the fixed place, which not only adversely affects the cerealing ability but also collides with other components. Cause failure. For this reason, it is necessary to position the projecting piece 20 at least in two places and prevent it from rotating with respect to the conveyor belt 14. However, since the length b of the mounting piece 21 ≤ the width w of the mounting piece 21 ≈ the width w1 of the endless belt, it is necessary to form two screwing portions in the width w direction of the narrow mounting piece 21 in terms of dimensions. It is difficult and two screwing portions cannot be formed in the length b direction of the mounting piece 21 which is narrower than that. For this reason, in the present embodiment, the mounting piece 21 with respect to the transport belt 14 is screwed with a nut 25 through a flat head screw 24 as a screwing portion to fix the mounting piece 21 to the transport belt 14, and the tip of the mounting piece 21 A pointed claw piece 23 is bent from the edge, and this claw piece 23 is bitten into the conveying belt 14 to form a rotation stop portion of the protruding piece 20. Accordingly, the length b of the mounting piece 21 including the claw piece 23 ≦ the width w1 of the mounting piece 21 ≈the width w1 of the endless belt, as a specific dimension, the length b≈10 mm of the mounting piece 21 including the claw piece 23, Even if there is a restriction that the width w of the mounting piece 21 ≈ the width w1 of the endless belt 12 mm, the length b of the mounting piece 21 is made as short as possible, and the countersunk screw 24 (screw fixing portion) and the claw piece 23, the protruding piece 20 can be fixed to the conveyor belt 14 in a non-rotating state. The length b1 of the conveying piece 22 is approximately 25 mm.

  Next, the usage example according to various uses is demonstrated about the belt type elevator 1 which is an Example of this invention. FIG. 5 is an example of use when the transport apparatus of the present invention is provided in the subsequent stage of various grain processing apparatuses to bag the grains, and FIG. 6 shows two sorters arranged in succession.

Although not shown in FIG. 5, various grain processing apparatuses are provided, and the processed grains are guided to the grain input hopper 53 of the belt type elevator 1 of the present invention. The belt type elevator 1 of the present invention is driven upward by a driving motor 70 provided below, and is moved upward by a conveying means housed in a conveying device casing 40 including a casing portion 30 and an outer lid portion 50. It is cerealed and transported and sent out from the sending unit 90. The bellows tube 33 at the tip of the delivery unit 90 is connected so as to deliver the grain into the gate G attached by a holding member 56 having an appropriate configuration. The detailed configuration of the gate G has been filed by the present applicant as a previous application (Japanese Patent Application No. 2008-264197), and the gate G has two bag bags 80 ( In FIG. 5, only one bag is shown).

  The usage example shown in FIG. 6 will be described in more detail. In FIG. 6, two sorters 81 and 82 are continuously arranged by the belt type elevator 1 of the present invention. Since the present invention is not related to a sorter, the configuration of the sorter will not be described in detail. From the chute 83 attached to the exit of the immature rice of the first sorter 81, immature rice is introduced into the grain input hopper 53 of the belt type elevator 1 of the present invention, conveyed and cerealed by the belt type elevator 1 of the present invention, and bellows. It is conveyed from the pipe 33 to the supply port of the second sorter 82.

  The usage example shown in FIG. 7 will be described in more detail. The fresh rice introduced into the grain input hopper 53 of the belt-type elevator 1 of the present invention from the fresh rice port 86 of the rice huller 85 is conveyed and cerealed by the belt-type elevator 1 of the present invention, and is removed from the bellows tube 33. Return to the hopper 87 of the sliding machine 85 again. In the example of use here, the sending part 90 of the belt type elevator 1 is attached in the opposite direction to the other examples of use (so that it is sent to the same side as the grain charging hopper 53 side).

  As described above, according to the present embodiment, the conveyor belt 14 and the projecting piece 20 are configured as separate parts, and the projecting piece 20 is attached to the conveyor belt 14 so that the projecting piece 20 is integrally formed with the conveyor belt 14. The existing conveyor belt 14 can be used without forming the belt, and the manufacturing cost can be reduced. Further, when the projecting piece 20 is formed as a separate part and the projecting piece 20 is attached to the conveyor belt 14, a strong mounting structure is required so that the projecting piece 20 does not rotate with respect to the conveyor belt 14. 21. Length b ≦ width w≈width w1 of the endless belt 21 is restricted, but the mounting piece 21 is screwed to the mounting piece 21 with a nut 25 through a countersunk screw 24, and the tip of the mounting piece 21 has a pointed tip. The claw piece 23 is bent and formed, and the claw piece 23 is bitten into the conveying belt 14 to form a detent portion of the protruding piece 20 so that the length b of the mounting piece 21 is made as short as possible. In addition, the protruding piece 20 can be fixed to the conveyor belt 14 in a non-rotating state by a countersunk screw 24 (screw fixing portion) and a claw piece 23.
