The height of the scraping attachment is set to be lower than the height of the scraping attachment. By from between the write port forming side walls projecting upwardly between the right and left pair of inclined side walls is obtained by solving the problems as described above.

  In addition to the configuration of the invention according to claim 1, the present invention according to claim 2 is a lateral bending guide surface that guides swallowing of the flow of the granular material from the supply part of the conveyor case to the granular material carrying-out side by lateral bending. However, it is formed by partially cutting off the front wall on the powder particle carrying-out side that forms a part of the supply part and the discharge channel forming side wall on the powder particle carrying-out side that is continuous with the intake port forming side wall. Thus, the above-described problems are further solved.

  According to a third aspect of the present invention, in addition to the configuration of the first or second aspect of the present invention, the flow of the granular material is swallowed by vertical bending from the supply part of the conveyor case to the granular material discharge side. A vertical bending guide surface is formed by partially cutting off the front wall on the powder particle carrying-out side that forms a part of the supply unit and the unloading path forming ceiling wall on the powder particle carrying-out side that is continuous with the supply unit. Therefore, the above-described problems are further solved.

  According to a fourth aspect of the present invention, in addition to the configuration of the invention according to any one of the first to third aspects, the granular material scraping attachment is held from both sides of the chain body toward the center. The above-described problems are further solved by being formed so as to be held.

  According to a fifth aspect of the present invention, in addition to the structure according to any one of the first to fourth aspects, a chain cover that covers an upper traveling portion of the conveyor chain and an upper traveling side portion of the conveyor chain The above-described problems are further solved by the fact that the guide rail that guides the vehicle is installed in the drop supply area defined in the supply part of the conveyor case.

Can be transported to the particle unloading side while scraping with the chain scraping attachment of the chain Not hunting, it is possible to obtain the unique effect of the present invention as follows.

  That is, according to the case type granular material flow conveyor of the present invention according to claim 1, the supply part of the granular material is on the case upper side of the conveyor case, and in the left-right direction of the portion where the lower traveling part travels in the conveyor case. At least a pair of left and right supply port forming sidewalls arranged oppositely wider than the case width, a pair of left and right inclined side walls connected to the supply port forming side wall, and a pair of left and right intake port forming side walls respectively connected to the inclined side wall As a result, the powder particles fall down to the intake port forming side wall through the supply port forming side wall and the inclined side wall assembled from the upper side of the case to the lower side of the case in the supply unit. Since it is guided and collected by its own weight, it is possible to smoothly drop and take in the granular material into the lower traveling portion of the conveyor chain traveling under the case.

  And the intake port forming side wall that takes in the granular material is formed in a state of being closely arranged to both sides of the lower traveling portion of the conveyor chain, so that the granular material is aggregated without being distributed to the lower traveling portion of the conveyor chain. Therefore, the granular material can be reliably dropped and taken into the lower traveling portion of the conveyor chain under the case in the supply unit.

  Moreover, the height dimension of the intake port forming side wall of the granular material scraping attachment is such that the granular material scraping attachment in the lower traveling part scrapes off the clogging of the granular material generated across the pair of left and right inclined sidewalls. The conveyor case is set lower than the height dimension, and the powder body scraping attachment of the lower traveling part protrudes upward between the pair of left and right intake port forming side walls and between the pair of left and right inclined side walls. Even if the granular material called “bridge” is clogged under the inner case, the granular material scraping attachment protrudes upward from the intake opening forming side wall and scratches the bottom of the granular material bridge to cut it. Therefore, the bridge generated in the powder under the case is automatically broken and continuous smooth continuous conveyance without powder clogging can be realized and the powder clog is solved. The maintenance work to be avoided.

  Further, the present invention according to claim 2 is a horizontal bending that in addition to the effect of the invention according to claim 1, swallows and induces the flow of the granular material from the supply part of the conveyor case to the discharging side of the granular material. By the guide surface being formed by partially cutting off the front wall on the powder particle carry-out side forming a part of the supply part and the discharge passage forming side wall on the powder particle carry-out side continuous with the intake port forming side wall Because the flow of the granular material that moves from the conveyor case supply section to the granular material discharge side gently bends without sharply narrowing, the granular material clogging toward the granular material discharge side in the conveyor case In addition, it is possible to realize continuous smooth continuous conveyance without any maintenance and to avoid maintenance work for eliminating clogging of the granular material at the front side of the granular material carrying-out side.

  In addition to the effect of the invention according to claim 1 or claim 2, the present invention according to claim 3 induces swallowing of the flow of powder from the supply part of the conveyor case to the discharge side of the powder by vertical bending. The vertical bend guide surface is formed by partially cutting away the front wall on the particle carrying-out side forming a part of the supply unit and the carrying-out path forming ceiling wall on the particle carrying-out side continuous with the supply unit. Because of this, the flow of the granular material that moves from the conveyor case supply section to the granular material unloading side gently bends without being sharply narrowed, so the granular material moving toward the granular material unloading side in the conveyor case It is possible to realize continuous smooth continuous conveyance without clogging, and to avoid maintenance work for eliminating clogging of the granular material at the front side of the granular material carrying-out side.

  In addition to the effect of the invention according to any one of claims 1 to 3, the present invention according to claim 4 is configured such that the granular material scraping attachment is held from both sides of the chain body toward the center. As a result, the powder scraping attachment scrapes the powder bridge vertically and horizontally without resistance, and breaks the powder bridge generated in the falling supply area. Can completely eliminate clogging of powder particles.

  In addition to the effect of the invention according to any one of claims 1 to 4, the present invention according to claim 5 includes a chain cover that covers the upper traveling portion of the conveyor chain and an upper traveling side portion of the conveyor chain. The guide rail that guides traveling is installed in the drop supply area defined in the supply part of the conveyor case, so that the powder supplied to this drop supply area is not caught by the guide rail in the drop supply area. Even if it rubs through smoothly or gets caught, it is shaken off by the upper running part of the conveyor chain and easily falls to the lower running part of the conveyor chain and is used for transportation, so it is supplied to the drop supply area in the supply unit It is possible to avoid the accumulated particles from staying on or accumulating on the chain body or guide rail.

In addition to the effect of the invention according to claim 5, the present invention according to claim 6 is such that the chain cover is formed wider than the assembly width of the chain body, so that the chain cover is In order to reliably cover the upper area, it is possible to avoid the particles supplied to the drop supply area in the supply section from falling directly on the chain body above the case and staying or accumulating, and into the chain body Prevents fine powders from entering and ensures long-term chain function.
And the upper travel part of the conveyor chain in a state where the powder scraping attachment protrudes from the chain cover on both sides by forming the cover width of the chain cover narrower than the protruding width of the powder scraping attachment. Since the clogging of the granular material called “bridge” hangs over the chain cover on the upper side of the case, the attachment of the granular material is attracted by the granular material. In order to crush and sever without hanging the hanging part of the bridge consisting of, the bridge of the powder that occurs on the upper side of the case in the fall supply area is automatically and reliably broken down and there is no clogging of the powder Smooth transportation can be realized.

  The present invention includes a long conveyor case in which a wide supply part for supplying powder particles is dropped from the upper side of the case to the lower side of the case, and is installed along the conveying line. And a conveyor chain with a plurality of granular material scraping attachments attached to the chain body that circulates in the conveyor chain, and the lower traveling part of the conveyor chain scrapes and conveys granular material under the case in the conveyor case In the case-type granular material flow conveyor in which the upper traveling part of the conveyor travels back on the upper side of the case inside the conveyor case, the supply part of the granular material is on the upper side of the conveyor case, and the left and right of the part where the lower traveling part travels in the conveyor case A pair of left and right supply part forming side walls that are arranged to face each other wider than the case width in the direction, and the supply part forming side wall A pair of left and right inclined side walls that guide and collect powder particles from the upper side of the case to the lower side of the case, and the lower part of the conveyor chain in a state of being closely connected to both sides of the lower running part of the conveyor chain by connecting to the inclined side walls. It is formed of at least a pair of left and right intake port forming side walls that allow the powder part to be taken into the running part, and the powder body scraping attachment of the lower running part is generated over the pair of left and right inclined side walls. In order to scrape clogs, the height of the intake port forming side wall is set lower than the height of the powder / granule scraping attachment that scrapes and conveys the lower side of the case inside the conveyor case. Part of the granular material scraping attachment protrudes upward between the pair of left and right intake side forming side walls and between the pair of left and right inclined side walls. As a result, the powder particles are reliably and smoothly dropped and taken into the conveyor chain below the case from the case upper side in the supply unit incorporated in the conveyor case, and the powder particle clogging in the supply unit is automatically eliminated. Any specific mode may be used as long as it can be smoothly and continuously conveyed.

  That is, as a specific chain form of the conveyor chain used for the case type granular material flow conveyor of the present invention, it is sufficient if the granular body scraping attachment is assembled to the chain main body. For example, the chain main body is a roller. Either a chain or a bush chain may be used, and the powder and particle scraping attachment may be assembled symmetrically on both sides of the chain body or alternately in a zigzag manner.

  In addition, regarding the specific form of the powder particle scraping attachment, the powder particles in the conveyor case are transported to the carry-out side while being scraped without causing sliding resistance with the conveyor case in the lower traveling portion of the conveyor chain. Any shape can be used as long as the bridge of powder particles is scraped off without resistance in the upper running part of the conveyor chain, for example, it is formed in an L-shape projecting from both sides of the chain body to the left and right. If it is made of a rib member formed, it is possible to break up the granular material bridge vertically without resistance, breaking it, and breaking the granular material bridge generated in the fall supply area. If it is made of rib members that protrude from the center toward the center, scrape the bridge of the powder particles vertically and horizontally without resistance. Shredding I, it is possible to break the bridges granular material occurring falling feed zone instantaneously.

  Furthermore, the specific form of the chain cover used in the case-type granular material flow conveyor of the present invention may be any form as long as it reliably covers the upper region of the chain body. If it is composed of left and right inclined plates assembled to the chain cover, it will be easy to slide on the chain cover even if the granular material supplied from the conveyor case supply part falls on the chain cover. Even if it is provided on the case upper side of the drop supply area, it is possible to avoid accumulation and retention of the powder and suppress the proliferation of the bridge made of the powder.

  That is, the cover width of the chain cover used in the case type granular material flow conveyor of the present invention is formed wider than the assembly width of the chain main body, so as to reliably cover the upper area of the chain main body.

The cover width of the chain cover is narrower than the protruding width of the granular material scraping attachment, and the upper part of the conveyor chain travels with the granular particle scraping attachment protruding from the chain cover on both sides. It is desirable to make it.
As a result, even if the clogging of the granular material called `` bridge '' occurs in the state where it drops over the chain cover in the falling supply area in the supply unit, the hanging portion of the bridge where the granular material scraping attachment occurs on the upper side of the case Since they are scraped off without being proliferated, the bridge of the powder particles generated on the upper side of the case in the drop supply area is automatically and reliably broken to perform continuous and smooth conveyance without clogging of the powder particles.

Furthermore, about the specific form of the conveyor case used for the case type granular material flow conveyor of the present invention, a wide supply part for supplying and dropping the granular material is incorporated from the upper side of the case to the lower side of the case, and is incorporated into the conveying line. Any case form may be used as long as it is possible to circulate and run a conveyor chain that is horizontally installed along with a plurality of powder particle scraping attachments that scrape powder particles.
Further, regarding the specific form of the supply section, a pair of left and right supply section forming side walls disposed opposite to each other wider than the case width on the upper side of the conveyor case and the supply section forming side wall are respectively connected to the case. A pair of left and right inclined side walls that guide and collect from the upper side to the lower side of the case, and powder particles are taken into the lower travel part of the conveyor chain in a state of being connected to each side of the lower travel part of the conveyor chain. As long as it is formed at least by the intake port forming side wall to be formed and the front wall that is connected to the supply portion forming side wall and the inclined side wall and surrounds a part of the supply portion, for example, a conveyor If the fall supply area in the case narrows from the upper traveling part of the conveyor chain to the lower traveling part, the conveyor case It can be supplied granule to fall feed zone from the feed portion is intensively fall from the upper running portion of the drop-supply region of the conveyor chain to the lower running portion.

It is a figure explaining the arrangement | positioning form of a bending guide surface.

First, as shown in FIG. 1, a case-type granular material flow conveyor 100 according to an embodiment of the present invention incorporates a supply unit 111 that drops and supplies a granular material M from the upper side of the case toward the lower side of the case. A conveyor case 110 is provided horizontally along the transfer line, and a conveyor chain 140 is wound around the drive sprocket 120 and the driven sprocket 130 in the conveyor case 110 and circulates in a vertical direction.
Thereby, the granular material M dropped and supplied to the inside 111 of the conveyor case 110 is conveyed to the granular material carrying-out side by the conveyor chain 140 in a dense state without diffusing outside the case. .
Here, the code | symbol 112 in FIG. 1 is a discharge port which discharge | emits the granular material M arrange | positioned under the granular material conveyance side lower side of the conveyor case 110, and was conveyed by the conveyor chain 140, and the code | symbol 140a is It is a lower traveling portion of the conveyor chain 140 that conveys the granular material M while traveling from the driven sprocket 130 toward the driving sprocket 120, and reference numeral 140 b denotes the conveyor chain 140 that travels from the driving sprocket 120 toward the driven sprocket 130. It is the upper running part.

  Then, as shown in FIGS. 2 to 3, on the upper side of the drop supply area S defined in the supply unit 111 of the conveyor case 110, a chain cover 150 that covers the upper traveling portion 140 b of the conveyor chain 140, A guide rail 160 that guides the upper traveling portion 140b of the conveyor chain 140 is provided.

Further, as shown in FIG. 2, the drop supply area S in the supply unit 111 in this embodiment is narrowed from the upper traveling portion 140b of the conveyor chain 140 toward the lower traveling portion 140a. The granular material M is configured to pass through the upper traveling portion 140b of the conveyor chain 140 and fall intensively toward the lower traveling portion 140a.
Thereby, in the lower traveling part 140a of the conveyor chain 140, the granular material M is conveyed to the granular material carrying-out side while being efficiently scraped.

On the other hand, as shown in FIG. 4, the upper and lower partition plates 113 that divide the conveyor case 110 in the vertical direction and the granular material delivery side are provided in the front and rear case regions except the supply region of the case-type granular material flow conveyor 100 described above. Are formed so as to isolate and seal the lower traveling portion 140a and the upper traveling portion 140b of the conveyor chain 140 from each other.
4 is a case top plate disposed at the upper part of the conveyor case 110, reference numeral 116 is a case bottom plate disposed at the lower part of the conveyor case 110, and reference numeral 117 is the conveyor case 110. It is a case side board arrange | positioned at the side part.

Further, as shown in FIG. 5, the conveyor chain 140 used in the case-type granular material flow conveyor 100 of the present embodiment is composed of a normal roller chain and circulates around the conveyor case 110 vertically. 141 and a granular material scraping attachment 142 that is attached to both sides of the chain main body 141 and scrapes the granular material M.
Further, the granular material scraping attachment 142 is constituted by a rib member formed so as to protrude from both sides of the chain main body 141 toward the center.
As a result, the granular material scraping attachment 142 scrapes the bridge B of the granular material M vertically and horizontally without resistance, so that the granular material generated on the case upper side or the case lower side of the drop supply area S. The bridge B made of M is instantaneously broken to completely eliminate clogging of the granular material M.

Furthermore, as shown in FIG. 2, the chain cover 150 in the case type granular material flow conveyor 100 according to the present embodiment holds the left and right inclined plates on the upper side of the case of the drop supply area S defined in the supply unit 111. The cover width W1 of the chain cover 150 is formed wider than the assembly width W2 of the chain main body 141 and is mounted so as to cover the upper running portion 140b of the conveyor chain 140.
Thereby, even if the granular material M supplied from above the supply unit 111 falls on the chain cover 150 on the upper side of the case, it is easy to slide down on the chain cover 150 made of left and right inclined plates. Even if 150 is provided on the upper side of the case in the fall supply area S, accumulation and retention of the granular material M is avoided on the upper side of the case in the falling supply area S and the proliferation of the bridge B made of the granular material M is suppressed. ing.

Further, the cover width W1 of the chain cover 150 is formed to be narrower than the protruding width W3 of the granular material scraping attachment 142, and the granular chain scraping attachment 142 protrudes from the chain cover 150 to both sides. The upper traveling portion 140b of 140 is caused to travel.
Thereby, even if the clogging of the granular material M referred to as “bridge B” occurs in the drop supply area S in the supply unit 111 in a state of hanging down across the chain cover 150 on the upper side of the case, the granular material scavenging attachment 142 Therefore, the bridge B of the granular material M generated on the upper side of the falling supply area S is automatically and reliably broken down so that the granular material M is not clogged. It is designed to perform continuous and smooth conveyance.

And the guide rail 160 in the case type granular material flow conveyor 100 of a present Example is constructed by the case upper side of the fall supply area S in the supply part 111, as shown in FIG. The upper traveling portion 140b of the conveyor chain 140 traveling toward 130 is provided to be supported and guided.
As a result, the granular material M supplied to the drop supply area S in the supply unit 111 is smoothly rubbed without being caught by the guide rail 160 of the drop supply area S, or even if it is caught, the upper running portion of the conveyor chain 140 The granular material M that is shaken down to the lower side of the case by 140b, is easily dropped to the lower traveling portion 140a of the conveyor chain 140, is provided for conveyance, and is supplied from above the supply unit 111 to the drop supply area S. It avoids staying or accumulating on the upper chain body 141 or the guide rail 160.

Then, the specific arrangement | positioning form of the supply part 111 which the case type granular material flow conveyor 100 of a present Example is the most characteristic is demonstrated in detail below based on FIG. 6 thru | or FIG.
That is, the supply unit 111 described above is a pair of left and right supply port forming sidewalls 111a disposed on the upper side of the conveyor case 110 so as to face each other wider than the case width in the left and right direction of the portion where the lower traveling portion 140a travels in the conveyor case 110. And a pair of left and right inclined side walls 111b connected to the supply port forming side walls 111a and a pair of left and right intake port forming side walls 111c connected to the inclined side walls 111b, respectively.
Thereby, the granular material M reaches the intake port forming side wall 111c through the supply port forming side wall 111a and the inclined side wall 111b assembled from the upper side of the case toward the lower side of the case in the supply unit 111. Since the body M is guided and collected by the falling weight of the body M, the granular material M is smoothly dropped and taken into the lower traveling portion 140a of the conveyor chain 140 traveling below the case.

And the intake port formation side wall 111c which takes in the granular material M is formed in the state arrange | positioned close to the both sides of the lower running part 140a of the conveyor chain 140, respectively.
Thereby, since the granular material M is collected intensively without being dispersed in the lower traveling portion 140a of the conveyor chain 140, the granular material M is surely dropped into the lower traveling portion 140a of the conveyor chain 140 and taken in. It is supposed to be.

Further, the height dimension H1 of the intake port forming side wall 111c is set so that the granular material scraping attachment 142 of the lower traveling portion 140a scrapes off the clogging of the granular material generated across the pair of left and right inclined side walls 111b. It is set lower than the height dimension H2 of the body scraping attachment 142, and the granular material scraping attachment 142 of the lower traveling portion 140a is between the pair of left and right intake port forming sidewalls 111c and between the pair of left and right inclined sidewalls 111b. Therefore, even if the granular material M called “bridge” is clogged under the case in the conveyor case 110, the granular material scraping attachment 142 is located above the intake port forming side wall 111c. It protrudes and scrapes off the bottom of the bridge of the granular material M to cut it.
For this reason, in the present embodiment, the bridge generated in the granular material M on the lower side of the case is automatically broken to realize continuous smooth continuous conveyance without clogging of the granular material M, and clogging of the granular material M. It is possible to avoid maintenance work to solve the problem.

Furthermore, the granular material delivery side on which the lateral bending guide surface 111e that guides swallowing the flow of the granular material M from the supply unit 111 of the conveyor case 110 to the granular material delivery side by lateral bending is formed. The front wall 111d and the unloading passage forming side wall 117a on the powder particle conveying side continuous with the intake port forming side wall 111c are partially cut away.
The horizontal bending guide surface 111e causes the powder M in the conveyor case 110 to bend gently in a horizontal direction without suddenly narrowing the flow of the powder M moving from the supply unit 111 of the conveyor case 110 to the powder particle carrying-out side. It is possible to achieve continuous smooth continuous conveyance without clogging of the granular material M toward the granular material delivery side and to avoid maintenance work for eliminating the clogging of the granular material M at the front side of the granular material delivery side. It is possible.

In addition, a vertical bend guide surface 111f that guides swallowing of the flow of the powder M from the supply unit 111 of the conveyor case 110 to the powder take-out side by a vertical bend forms a part of the supply unit 111. The front wall 111d and the delivery path forming ceiling wall 114 on the powder particle delivery side continuous to the supply unit 111 are partially cut away.
The vertical bending guide surface 111f causes the flow of the granular material M, which moves from the supply unit 111 of the conveyor case 110 to the granular material discharge side of the conveyor case 110, to be gently bent without being sharply narrowed. The maintenance work for eliminating clogging of the granular material M in the front part of the granular material carrying-out side while realizing continuous smooth continuous conveyance without clogging of the granular material M toward the granular material carrying-out side in 110. It is possible to avoid it.

The case type granular material flow conveyor 100 which is one Example of this invention operate | moves as follows.
As shown in FIG. 2, the drop supply area S in the supply unit 111 is formed so as to narrow from the upper traveling part 140b of the conveyor chain 140 toward the lower traveling part 140a. The granular material M supplied to the region S is collectively dropped from the upper traveling portion 140b of the conveyor chain 140 in the falling supply region S to the lower traveling portion 140a, and the granular material scraping projecting to both sides of the chain body 141, respectively. The moving attachment 142 conveys the granular material M in the conveyor case 110 to the granular material unloading side without scraping resistance with the conveyor case 110 in the lower traveling portion 140b.

At this time, since the cover width W1 of the chain cover 150 is formed narrower than the protruding width W3 of the granular material scraping attachment 142, the granular material referred to as “bridge B” in the drop supply area S in the supply unit 111. Even when the body M is clogged over the chain cover 150 on the upper side of the case, the granular material scraping attachment 142 made of the rib member does not multiply the hanging portion of the bridge B made of the granular material M. Scratch and shred.
Moreover, since the granular material scraping attachment 142 is formed so as to be held from both sides of the chain body 141 toward the center, the bridge B of the granular material M is scraped vertically and horizontally without resistance. Therefore, the bridge B of the granular material M generated on the case upper side of the drop supply area S is automatically and reliably broken.

  And the supply part 111 of the granular material M is a pair of left and right supply port forming side walls 111a arranged to face each other wider than the case width, and a pair of left and right inclined side walls 111b respectively connected to these supply port forming side walls 111a and the inclination thereof. Since it is formed at least by the pair of left and right intake port forming side walls 111c respectively connected to the side wall 111b, the supply port forming side wall in which the granular material M is assembled from the case upper side to the case lower side in the supply unit 111 It is guided and collected by the falling weight of the granular material M until it reaches the intake port forming side wall 111c through the 111a and the inclined side wall 111b sequentially.

  And since the intake port formation side wall 111c which takes in the granular material M is formed in the state arrange | positioned close to the both sides of the lower running part 140a of the conveyor chain 140, respectively, the granular material M is the lower running part 140a of the conveyor chain 140. Collected in a centralized manner without being distributed.

  Further, since the height dimension H1 of the intake port forming side wall 111c is set lower than the height dimension H2 of the granular material scraping attachment 142, a powder referred to as “bridge B” is provided below the case in the supply unit 111. Even if the granular material M is clogged, the granular material scraping attachment 142 protrudes upward from the intake port forming side wall 111c and scrapes off the bottom of the bridge B of the granular material M to cut it.

  The case-type granular material flow conveyor 100 according to the embodiment of the present invention thus obtained includes a conveyor case 110 in which the supply unit 111 of the granular material M is incorporated from the upper side of the case toward the lower side of the case, A conveyor chain 140 that circulates in the vertical direction in the conveyor case 110, a chain cover 150 that covers the upper running portion 140b of the conveyor chain 140 above the case of the drop supply area S defined in the supply unit 111, and a conveyor chain 140 and a guide rail 160 that guides the upper traveling portion 140 b of the upper traveling portion 140, and the conveyor chain 140 includes a powder and particle scraping attachment 142 that protrudes on both sides of the chain main body 141. The “bulb” that tends to be formed on the upper side of the case by the powder M supplied to the supply area S The granular material M called “edge B” can be automatically broken to realize continuous and smooth conveyance without clogging of the granular material M, and the cover width W1 of the chain cover 150 is equal to the assembly width W2 of the chain body 141. By forming the wider and narrower than the protruding width W3 of the granular material scraping attachment 142, the granular material M supplied from the upper side of the supply unit 111 to the drop supply region S is the chain body 141 on the upper side of the case. It is possible to avoid dropping and staying or accumulating directly on the top, preventing fine powder from entering the chain body 140, and ensuring the chain function over a long period of time.

  And the height dimension H1 of the intake port forming side wall 111c constituting a part of the supply unit 111 is set lower than the height dimension H2 of the granular material scraping attachment 142 to be scraped and conveyed on the lower side of the case in the supply unit 111. The granular material M is surely and smoothly dropped and taken into the lower traveling portion 140a of the conveyor chain 140 at the lower side of the case in the supply unit 111, and the granular material M on the lower side of the case in the supply unit 111 The effect is enormous, such as automatically eliminating clogging and smooth continuous conveyance.
