Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lateral feed transport device provided with a transport conveyor for transporting grains such as rice from a supply part to a discharge part of a machine casing installed substantially horizontally,
In particular, the present invention was devised for the carrier of the conveyor.

[0002]

2. Description of the Related Art In the publicly known Japanese Patent Publication No. 2-36484, an annular belt is provided on a machine casing elongated in the conveying direction, and a plurality of conveyers are provided at predetermined intervals on the annular belt.
It describes a configuration in which a slight gap is provided between the lower surface of the carrier and the bottom plate.

[0003]

In the above-mentioned known conveyer, a plurality of conveyers are provided on an annular belt at predetermined intervals, and as shown in FIG. 15, there is a slight gap between the lower surface of the conveyer c and the bottom plate b. Although it is a gap, there is a problem that the residual grain cannot be discharged because it is moved with a gap of about 1 cm. In this case, the scraper is an elastic member that is always in sliding contact with the bottom plate separately from the conveyor on the annular belt (the above-mentioned publication describes a scraper conveyor that does not contact the bottom plate as a conventional example, but the scraper originally slides on the bottom plate at all times. A configuration is also known in which a scraper is contacted to convey the residual grain), but since the scraper is always in sliding contact with the bottom plate, another problem is that the scraper breaks and the damaged substance enters the conveyed substance as a foreign substance. There is. In particular, recently, the rice after milling has a tendency to be cooked as it is called "non-washed rice". Therefore, if foreign matter is mixed in the conveyed product, the value of the grain is significantly reduced and the conveying device having a scraper is provided. In the present situation, a considerably expensive sorter is provided on the conveyance route. Therefore, if it is a transport device that does not require a scraper,
A considerably expensive sorter is not required, but if the scraper is not needed, the grains will remain in the machine casing, and the residual grains will not be inconvenient, such as moldy or rodent. It was impossible to realize it while hoping that a scraper was unnecessary. The present application eliminates the need for a scraper to prevent damages from entering foreign materials as foreign matter, and provides a grain outlet at a portion where the transport body is hard to act to easily remove residual grain. It makes it possible to take out the scraper and makes it possible to eliminate the need for a scraper and discharge the residual grain.

[0004]

It is an object of the present invention to provide a conveyer that does not require a scraper, ensure the discharge of residual grains, suppress and prevent grain damage, reduce and suppress the generation of vibration and noise, improve durability, and facilitate maintenance work. Cost reduction.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings.
Is a machine casing of the lateral transport device, and is formed long in the transport direction. A supply unit 2 is provided at a position above one end of the machine casing 1, and a discharge unit 6 having an outlet 5 is provided at the other end. In this case, one or a plurality of supply units 2 may be provided in the intermediate portion, and similarly, one or a plurality of discharge portions 6 may be provided in the intermediate portion other than the discharge portion 6 at the other end. The discharge unit 6 is provided with a shutter (not shown) for opening and closing the outlet 5. The supply unit 2
A transport conveyor 7 is provided in the machine casing 1 between the supply port (not shown) and the discharge unit 6 at the other end. For convenience of explanation, if the transport direction of the transport conveyor 7 is the front-back direction, the transport conveyor 7
The driven gear 8 is mounted by the driven shaft 9 in the machine casing 1 at the rear of the supply unit 2. A drive gear 10 is mounted by a drive shaft 11 in the machine casing 1 on the front side of the discharge portion 6 at the end.
A plurality of carriers 12 are provided between the driven gear 8 and the drive gear 10.
The endless chain 13 which constitutes the moving member Y provided at a predetermined interval is hung around.

In this case, the endless chain 13 includes the driven gear 8 on the front side of the supply unit 2 and the drive gear 10 on the front side of the end outlet 5.
And the carrier 12 is moved from the front side of the supply unit 2 (the upper side in the conveying direction) to the front side of the terminal outlet 5 to convey the grain. Thus, a grain passage 18 having a bottom plate 16 and a standing plate 17 standing upright on the left and right sides of the bottom plate 16 is provided in the machine casing 1, and each of the carriers 12 has the grain flow. With a gap smaller than the grain with respect to the inner surface of the road 18, the support mechanism X is configured to move in a state of being directly guided and supported by the support mechanism X without lateral deflection or one-sided traveling. That is, conventionally, a guide that guides the moving member Y such as the endless chain 13 is provided instead of the carrier 12, and the support mechanism X that directly guides the carrier 12 is not provided. Then, a gap is provided between the carrier 12 and the grain flow path 18 (machine casing 1) to prevent the carrier 12 from hitting the inner surface of the machine casing 1 from generating noise. Grains that were not conveyed by the body 12 were left and remained as a residue.

In this case, the vertical gap between the bottom plate 16 and
Although the scraper, which is an elastic member, is always in sliding contact with the bottom plate 16, it is in frequent sliding contact and may be severely damaged and mixed in the conveyed product. Therefore, the carrier 12 is separated from the bottom plate 16 by the support mechanism X in a gap (0
If it is configured to move with a grain path of ~ 1 mm), the grain flow path 1
It is conveyed without generating the residual grain in 8. Further, conventionally, as shown in FIG. 15, the side plate a is inclined with respect to the bottom plate b to prevent contact between the carrier c and the side plate a. However, the grain flow path is in a direction intersecting with the traveling direction of the carrier c. If d is formed to be wide, the carrying force of the carrier c acts on the grain e so as to escape laterally as shown in FIG.
Alternatively, it takes a considerable amount of time, and it is very difficult to judge how much the discharge operation time should be set.

Therefore, if the carrier 12 is moved by the support mechanism X with a gap (0 to 1 mm) smaller than the grain between the carrier 12 and the upright plate 17, the inside of the grain flow path 18 is further increased. It is transported without generating the residual grain. Then, the support mechanism X spreads the grain flow path 18 laterally as it extends upward from the bottom plate 16, the substantially vertical standing plates 17 on the left and right sides of the bottom plate 16, and the upper end of the standing plate 17. The transporting body 12 is provided with the left and right slanting slide contact surfaces 21 which are always in slidable contact with the upper surfaces of the left and right slanting support plate portions 20 by the plate member made of synthetic resin. Have and configure. That is, the left and right slanted slide contact surfaces 21 are moved in a state of slidingly contacting the slanted support plate portion 20 of the machine casing 1 by the weight of the carrier 12 so that they are always positioned at the center of the left and right slanted support plate portions 20. The transporting body 12 is guided to prevent the moving transporting body 12 from swinging left and right. Therefore, the carrier 12 is
The lower side edge 22 below the inclined sliding contact surface 21 is slidably contacted by the supporting mechanism X to the upper surface of the inclined support plate portion 20 by the support mechanism X, and a gap (0
It can be easily set to move with ~ 1mm).

Further, since the left and right slanted sliding contact surfaces 21 are slidably supported by the slanted support plate portion 20 of the machine casing 1 and move without any room for further lowering, the lower edge of the carrier 12 24 is easily set to move with a gap (0 to 1 mm) smaller than the grain than the upper surface of the bottom plate 16 in a state where the inclined sliding contact surface 21 is in sliding contact with the upper surface of the inclined support plate portion 20. it can. This makes it unnecessary to separately attach a so-called scraper to any of the transport bodies 12. In other words,
On the upper part of the grain flow path 18 formed in the machine casing 1, the grain flow path 1
The inclined support plate portion 20 that rises toward both outer sides in the direction intersecting with the movement direction of 8 is provided over the movement direction, and the carrier 12 that moves in the grain flow path 18 slides on the inclined support plate portion 20. By providing the slanting sliding contact surface 21 that moves, there is a gap smaller than the grain (rice grain) between the upright plate 17 of the grain flow path 18 and the left and right side edges and lower side edges 22, and the bottom plate 16 is provided. Is configured to move in sliding contact.

Therefore, the depth of the standing plate 17 and the width of the bottom plate 16 are arbitrary, and the inclined support plate portion is so arranged that the carrier 12 moves in the center according to the depth of the standing plate 17 and the width of the bottom plate 16. The inclination angles of 20 and the inclined sliding contact surface 21 may be set. Thus, the endless chain 13 is formed in an endless shape by detachably connecting both side links 25 in the front-rear direction with a locking shaft member 26, and the left and right sides of a predetermined one of the both side links 25 are formed in the traveling direction. It is preferable that the carrier 12 is integrally formed of synthetic resin so as to project in the intersecting direction, because the manufacturing is easy. In this case, the carrier 12 is made to project laterally to each of the pair of left and right side links 25 in the front-rear direction of the endless chain 13, and the carrier lower edge 24 of the carrier 12 is positioned below the lower edges of the side links 25. Although it may be positioned and integrally formed in the width direction of the bottom plate 16, if the carrier 12 is divided into left and right parts and integrally formed on the pair of both side links 25, the attachment (assembly) becomes easy. Is preferred. In this case, a gap 30 smaller than a grain (rice grain) is provided between the divided left and right carriers 12. The left and right links 25 are positioned with a roller 31 between which the locking shaft member 26 is inserted between them, and the ends of the locking shaft member 26 are detachably attached by a fastener 32 such as a split pin. 33 is a washer.

Therefore, even if one of the left and right carriers 12 is damaged, it can be easily replaced, which is preferable. Further, since the both side links 25 are connected by the locking shaft member 26 to form an endless shape, without using a special tool for exclusive use,
When the fastener 32 is removed, any of the many side links 25 can be removed. Therefore, the maintenance work of the endless chain 13 is facilitated, and the set length of the endless chain 13 with respect to the machine casing 1 is easily adjusted, which is preferable. Further, when the lower edge 24 of the carrier is formed on the lower edge chamfered inclined surface 34 which becomes higher toward the front side in the traveling direction of the carrier 12, even if the lower edge 24 of the carrier is temporarily in contact with the bottom plate 16, the lower edge of the carrier 12 is conveyed. Since the lowest portion of the lower edge chamfered inclined surface 34 serves as the lower edge 24 of the carrier body and does not need to make surface contact with the entire plate thickness surface of FIG. The carrier 12 may be configured to be moved in any of forward and backward directions (forward and backward) to move the grain to the supply unit 2 and the discharge unit 6 (for example, the supply unit 2 is provided at the center). , Discharge part 6 at both ends
Is provided, or the supply units 2 and the discharge units 6 are alternately arranged to convey between the supply units 2 and the discharge units 6). In this case, the lower edge chamfering slope is provided in both front and rear directions of the transport body 12. Face 34
To provide.

Further, the side links 25 and the upper surface of the carrier 12 which form the endless chain 13 are respectively formed on the grain falling surface 35 whose cross section is inclined so as to be gradually lowered with the apex of a triangular shape sandwiched therebetween. This is preferable since it is possible to prevent the grains from being left on the upper surfaces of the both-side links 25 and the carrier 12 as a residue. Reference numeral 36 denotes a support roller that supports the upward endless chain 13, and a plurality of support rollers are provided at predetermined intervals.
Reference numeral 37 denotes a floating prevention body for preventing the downward movement of the endless chain 13, and a plurality of floating prevention bodies are provided at predetermined intervals. Then,
A shutter 40 is provided at the outlet 5 of the discharge unit 6, the shutter 40 is formed of a flat plate, an actuator 41 such as a cylinder for moving the shutter 40 is provided at one end of the shutter 40, and the other end of the shutter 40 is provided at the other end. The bottom plate 16 is formed only by a blind plate that closes the opening 42, and the support mechanism X is provided above the shutter 40. 43
Is a frame to which the shutter 40 is attached, and 44 is an air outlet.

That is, the carrier 12 is formed with the inclined sliding contact surface 21 as described above, the opening 42 of the bottom plate 16 is exposed above the shutter 40, and the above-mentioned opening 42 is provided above. Standing plate 17 forming the grain flow path 18 and inclined support plate portion 2
By providing 0, the support mechanism X is provided above the shutter 40. Then, the carrier 12 is arranged with the drive gear 10 or the passive gear 8 around which the endless chain 13 is wound so that the carrier 12 passes below the supply unit 2 from the upstream side in the conveyance direction. The drive gear 1
0 or the bottom plate 16 below the passive gear 8 is provided with a residual grain discharge port 45 and an opening / closing shutter 46 for opening and closing the residual grain discharge port 45. Residual grain discharge port 45 of the embodiment
Is positioned rearward of the endless chain 13 having the rear end wound around the passive gear 8 and the front end is positioned forward of the front edge of the passive gear 8 to open the lower side of the passive gear 8 to remove residual grains. And the maintenance around the passive gear 8 is facilitated. A guide plate 47 is provided in the machine casing 1 on the upstream side in the transport direction of the residual grain discharge port 45. Information board 4
Numeral 7 is positioned diagonally below the rear side of the passive gear 8 so that the upper side in the conveying direction is higher and inclined lower as it approaches the residual grain discharge port 45, and the front end of the guide plate 47 is the rear end of the residual grain discharge port 45. To face. In addition, the drive gear 10 or the passive gear 8
The endless chain 13 going upwards and the endless chain 13 going downwards, which is on the lower side in the transport direction of the front side of the supply section 2.
A grain guide plate 48 is provided between them. Grain induction plate 48
Is a flat plate that is full in the width direction inside the machine casing 1 and is provided so that the upper side in the transport direction is inclined higher and lower toward the lower side in the transport direction. When falling, the grains placed on 13 are guided to the lower side in the transport direction and are prevented from falling to the driven gear 8 side.

[0015]

[Operation] Next, the operation will be described. When the motor is energized,
The drive gear 10 rotates, and the drive gear 10 moves to the endless chain 13
Is rotated to move the carrier 12 from the supply unit 2 to the discharge unit 6. Inside the machine casing 1, there is provided a grain flow path 18 having a bottom plate 16 and a substantially vertical standing plate 17 on the left and right sides of the bottom plate 16,
Since each carrier 12 is configured to move in a state of being directly guided and supported by the support mechanism X, each carrier 12 is entirely supported by the support mechanism X and does not laterally swing or shift to one side and the grain flow path 18 moves. Even if the gap between the bottom plate 16 and the carrier lower edge 24 of the carrier 12 on the inner surface of the grain flow path 18 is set to be smaller than the grain, the carrier lower edge 24 is moved to the center. Move without touching 16. Therefore,
The gap between the upper surface of the bottom plate 16 and the lower edge 24 of the carrier 12 of the carrier 12 can be made smaller than the grain and as narrow as possible without causing the noise that the carrier 12 hits the inner surface of the machine casing 1. There is no transfer residue due to and no residual grain is generated.

This eliminates the need for a scraper of an elastic member which is always in sliding contact with the bottom plate 16 and prevents a damaged product of the scraper from being mixed as a foreign matter into a conveyed product.
Further, when the gap between the upper surface of the bottom plate 16 and the lower edge 24 of the carrier of the carrier 12 is larger than the grain, the grain remaining on the bottom plate 16 and the grain subjected to the carrier action by the carrier 12 are vertically separated. Since there are layers, the grain at the boundary between the upper and lower layers will be rubbed against each other and damaged, but the gap between the upper surface of the bottom plate 16 and the lower edge 24 of the carrier 12 of the carrier 12 is a grain. Due to the smaller gap, the carrier 12 carries together the whole grain distributed vertically and prevents damage due to rubbing of the grains.

Since the carrier 12 moves while being guided and supported by the support mechanism X, the standing plates 17 on the left and right sides of the bottom plate 16 are provided substantially vertically while standing upright with the lower side edges 22 of the carrier 12. The gap between the plates 17 can be set to be smaller than the grain. Therefore, the carrying force of the carrier 12 extends to all the grains in the width direction of the grain flow path 18, and between the grains being carried by the carrier 12 and the remaining grains in the width direction as well. It prevents the phenomenon that the grains are rubbed against each other and damaged. That is, as shown in FIG. 15, when the grain flow path d is formed wide in the direction intersecting with the traveling direction of the carrier c, the carrying force of the carrier c is released to the side grain e laterally. This causes a phenomenon that the grains e operate and cannot be transported reliably, and the grains e rub against each other and are damaged, but this is prevented in the present application. Then, the support mechanism X causes the grain flow path 18 to move laterally as the smooth bottom plate 16, the substantially vertical standing plates 17 on the left and right sides of the bottom plate 16 and the upper end of the standing plate 17 are reached. The conveyance support 12 is formed by the inclined support plate portion 20 provided so as to spread, while each of the carriers 12 is made of a synthetic resin plate member, and the left and right inclined slide contact surfaces 21 are always in sliding contact with the upper surfaces of the left and right inclined support plate portions 20. Since it is configured with
The left and right slanted sliding contact surfaces 21 move with the slidable support plate portion 20 of the machine casing 1 slidably contacted by the weight of the carrier 12 without any room for further lowering. 24 moves from the upper surface of the bottom plate 16 with a gap smaller than the grain.

Therefore, if the inclined support plate portion 20 is provided above the upright plate 17 of the grain flow path 18 and the inclined slidable contact surface 21 matching the inclined support plate portion 20 is provided on the carrier 12, it is supported. The mechanism X can be configured, the configuration can be extremely simple, and the cost can be reduced. Further, since the left and right slanted slide contact surfaces 21 slide in contact with the slanted support plate portion 20, the carrier 12 is always guided so as to be positioned at the center of the left and right slanted support plate portions 20. , Tentatively, carrier 1
Even if a force is generated in 2 that swings to the left or right, the force that causes lateral swinging is a reaction force that the inclined sliding contact surface 21 abuts against the inclined support plate portion 20 and returns the carrier 12 to the other side. The carrier 12 is constantly guided and supported so as to be positioned and moved in the center of the grain flow paths 18 on the left and right. Therefore, the support mechanism X has a structure of guiding in the up-down direction, but also has an action of guiding and supporting in the width direction (left-right direction), so that the gap between the lower side edge 22 of the carrier 12 and the upright plate 17 is also reduced. The gap can be set smaller than the grain, which is more rational and lowers the cost.

As described above, when the gap between the lower side edge 22 of the carrier 12 and the standing plate 17 is set to be smaller than the grain, the grains between the standing plates 17 are laterally retracted by the standing plate 17. It is conveyed by the conveyance body 12 in a state where it cannot be carried out, the conveyance efficiency is improved, and the residual conveyance substance in the grain flow path 18 is not generated and is completely discharged in a short time. In this case, the inclined support plate portion 20 causes the grain to stand up when the transport amount decreases.
Although it has the effect of guiding it into the grain flow path 18 between them, the conveyance body 12 above the inclined sliding contact surface 21 moves above the inclined support plate portion 20, and below the inclined support plate portion 20 is left and right. Since the grains between the standing plates 17 can be conveyed without retracting to the side, the inclined support plate portion 20 has the function of guiding the grains into the grain flow path 18 between the standing plates 17 and improves the conveyance efficiency. Do not lower. Therefore, even if there are grains above the upper surface of the carrier 12, the tilted slide contact surface 2 of the carrier 12 is attached to the tilted support plate portion 20.
1 is slid on, the portion of the carrier 12 above the slidable sliding contact surface 21 acts on the grain above the inclined support plate portion 20, and the grain above this is Since it is transported in a vertically integrated manner due to the effects such as moving while being placed on a moving grain like a transport belt, it always provides a predetermined transport efficiency regardless of the amount of transport. While ensuring, minimize the occurrence of grain damage between the top and bottom. If the right and left widths of the inclined support plate portion 20 and the inclined sliding contact surface 21 are respectively set to the minimum areas required for guiding the conveyance body 12, it is possible to further prevent the occurrence of conveyance unevenness between the upper and lower portions and improve the conveyance efficiency. And is preferred. Thus, the carrier 12 is provided on both left and right sides of a predetermined one of the front and rear links 25 of the endless chain 13 so as to project in a direction intersecting with the traveling direction, and the carrier 12 and the both links 25 are integrated. Since it is made of synthetic resin, it is easy to manufacture, can be made lighter in weight than metal, and can reduce vibration during movement and minimize noise generation, which is preferable.

In this case, the carrier 12 is an endless chain 13
The pair of left and right side links 25 in the front-rear direction are laterally projected, and the carrier lower edge 24 of the carrier 12 located below the lower edges of the side links 25 is positioned to fill the bottom plate 16 in the width direction. At the same time, the carrier 12 is divided into left and right parts and integrally formed with the pair of both-side links 25, respectively. Therefore, if the both-side links 25 and the carrier 12 have the manufacturing accuracy of the plate thickness respectively, the assembling accuracy is ensured. This is preferable because it can be sufficiently performed and manufacturing and mounting (assembly) are easy. Further, since the gaps 30 smaller than the grain (rice grain) are provided between the lower edges 24 of the respective divided left and right carriers 12 to be mounted on the both-side links 25, the both-side links are formed. If the plate thickness of 25 and the length of the roller 31 are accurately manufactured, the assembling accuracy of the width of the both-side links 25 and the width dimension of the carrier 12 is sufficiently secured, and compared with the case where they are integrally formed. It is preferable because the accuracy can be easily secured. That is, the gap 30 smaller than the grain absorbs the variation, and improves the accuracy of the lateral width of the carrier 12, and thus the accuracy of setting the gap between the lower side edge 22 of the carrier 12 and the standing plate 17. Let

When the carrier 12 is divided into right and left,
Even if one of the left and right carriers 12 is damaged, it can be easily replaced.
It is suitable. In this case, the endless chain 13 is formed into an endless shape by connecting the both side links 25 with the locking shaft members 26, and the both side links 25 are connected through the locking shaft members 26 so as to be attachable and detachable. Since it is fixed by 32, when the fixing tool 32 is removed without using a special tool for exclusive use, any of the many side links 25 can be removed. Therefore, the maintenance work of the endless chain 13 is facilitated,
This is preferable because the set length of the endless chain 13 with respect to the machine casing 1 can be easily adjusted. Then, since the lower edge 24 of the carrier 12 is formed as the lower edge chamfered inclined surface 34 which becomes higher toward the front side in the traveling direction of the carrier 12, it is assumed that the lower edge 24 of the carrier is the bottom plate 16. Even if it contacts the upper surface, it does not make surface contact with the entire plate thickness surface (lower surface) of the carrier 12, but rather the lower edge 2 of the carrier which is the lowest portion of the lower edge chamfered inclined surface 34.
Since only 4 is in contact with the side of the line of sight, generation of abnormal noise can be suppressed to a minimum.

Further, when the lower edge chamfered inclined surface 34 is provided in both the front and rear directions of the carrier 12, the carrier 12 can be moved in either forward or backward (forward and backward) directions, and the feeding section 2 and the discharging section 6 can be moved. The degree of freedom of arrangement can be improved, and versatility can be improved. Then, the two-sided links 2 constituting the endless chain 13
5 and the upper surfaces of the carrier 12 are each formed in the grain-falling surface 35 by forming the cross section into a triangular corner shape.
This is preferable since it is possible to prevent the grains from being left on the upper surfaces of the both-side links 25 and the carrier 12 as a residue. Then,
A shutter 40 is provided at the outlet 5 of the discharge unit 6, the shutter 40 is formed of a flat plate, an actuator 41 such as a cylinder for moving the shutter 40 is provided at one end of the shutter 40, and the other end of the shutter 40 is provided at the other end. The bottom plate 16 is formed only by a blind plate that closes the opening 42, and the support mechanism X is provided above the shutter 40. It can prevent contact.

Further, since it is unnecessary to provide a separate guide member in the opening 42 of the bottom plate 16, the cost is reduced.
That is, conventionally, since a guide member for supporting the lower edge of the carrier from below is provided in the opening of the bottom plate, the problem that grains remain on this guide member and the guide member is the closed portion of the blind plate of the shutter. Since it is formed on the other end side than the above, the length of the shutter is increased by the provision of the guide member, and the entire apparatus is increased in size, which is solved. Therefore, the transporting body 12 is arranged with the drive gear 10 or the passive gear 8 around which the endless chain 13 is wound so that the transporting body 12 passes below the supply unit 2 from the upstream side in the transport direction. Since the bottom grain 16 below the drive gear 10 or the passive gear 8 is provided with the residual grain discharge port 45 and the opening / closing shutter 46 for opening / closing the residual grain discharge port 45, when the opening / closing shutter 46 is opened, Grains remaining on the bottom plate 16 below the drive gear 10 or the passive gear 8 on the upstream side in the transport direction from the supply unit 2 can be taken out. That is, even if the drive gear 10 or the passive gear 8 around which the endless chain 13 is wound is located on the upstream side of the feeding unit 2 in the conveying direction, the grains placed on the endless chain 13 that passes below the feeding unit 2 are moved. It may fall out and fall, and each side link 25 has a predetermined length and is a polygonal movement (movement) rather than a complete circular movement in side view, so that the gap between the carrier 12 and the bottom plate is large, especially the bottom plate. Since there is no scraper slidingly contacting the 16
Grains may remain on the upstream side in the conveying direction, but the remaining grains can be taken out. Therefore, the bottom plate 1
While avoiding the demerit of omitting the scraper that is slidably contacted with 6, it is possible to prevent the occurrence of the problem of damage and damage of the scraper being mixed in the conveyed product, and to recover the residual grain at the same time. Further, a guide plate 47 is provided on the lower rear side of the drive gear 10 or the passive gear 8 around which the endless chain 13 is wound, but since the residual grain can be taken out from the residual grain discharge port 45, the guide plate 47 can be taken out. Need not be formed in a complicated arc shape, but may be formed by an inclined plate that can guide and guide the grain to the residual grain discharge port 45, and in this respect also, the cost is reduced. In this case, the residual grain discharge port 45
Is located at the rear side of the endless chain 13 whose rear end is wound around the passive gear 8 and the front end is located at the front side of the front edge of the passive gear 8, so that the grain placed on the ascending endless chain 13 However, even if the grain is conveyed to the passive gear 8, the opening / closing shutter 46 that closes the residual grain discharging port 45 is placed on the upper side, so that the opening / closing shutter 46 can be easily taken out, which is preferable. In addition, the residual grain discharge port 45 is preferable because it can open the lower side of the passive gear 8 and facilitate maintenance of the periphery of the passive gear 8. Since the guide plate 47 is higher on the upper side in the conveying direction and is inclined lower as it approaches the residual grain discharge port 45, the front end of the guide plate 47 faces the rear end of the residual grain discharge port 45. Even if the grain on the going endless chain 13 is blown behind the passive gear 8 due to inertia, it is guided by the guide plate 47 onto the opening / closing shutter 46 and can be easily taken out. That is, since the residual grain discharge port 45 is formed in the portion below the passive gear 8 where the action of the carrier 12 is hard to receive, if the grain is taken out from the residual grain discharge port 45, the bottom plate 16 is removed. All of the grains are carried by the carrier 12. Therefore, if the guide plate 47 is configured to be steeper than the angle of repose, the accumulation of grains can be prevented, which is preferable. Further, a grain guide plate 48 is provided between the upward endless chain 13 and the downward endless chain 13 on the lower side in the transport direction of the drive gear 10 or the passive gear 8 and on the front side of the supply unit 2. Since the grain guiding plate 48 is provided with a flat plate in the width direction of the machine casing 1 that is wide in the width direction, the grain guiding plate 48 is inclined so that the upper side in the transport direction is higher and the lower side in the transport direction is lower. When passing, the grain placed on the endless chain 13 is prevented from being guided to the lower side in the transport direction when it falls and dropping to the driven gear 8 side, and normally the residual grain discharge port 4
The grains that have fallen to the front of 5 and are conveyed by the action of the carrier 12 and are not influenced by the carrier 12 are located on the residual grain discharge port 45, and as described above, the residual grains are discharged. Exit 45
Just take it out from.
