Among the known examples, the former is a scraper for discharging and transporting residual grains in the grain transport path because the transport body descends by its own weight above the discharge port and slides on the inclined support plate portion. There is a problem that is necessary.
The scraper is a consumable item. When the scraper is damaged, the damaged material is mixed into the conveyed product as a foreign object.
Moreover, since the grain breaks when pressure is applied during conveyance and the commercial value is lost, it is common knowledge that the bottom plate and the conveyance body are usually provided apart from each other. Although the scraper is unnecessary by moving it while supporting it, the residue on the bottom plate does not contact the inner edge of the grain conveyance path (especially the bottom plate) with the lower edge of the carrier. The remaining problem is that maintenance work is not easy.
That is, since there are a large number of transport bodies in the grain transport path and the bottom plate cannot be directly cleaned, cleaning is performed by removing the transport body together with the chain, which is a very troublesome operation.
The present application devised the guide movement of the transport body to eliminate the need for a scraper, to prevent the broken material from entering the transported material as a foreign object, and to remove even the granular residue. .

In the present invention, at least one supply unit 2 is provided on one side of the machine casing 1 that is formed long in the transport direction, and at least one discharge unit 6 is provided on the other side of the machine casing 1. Between the right and left sides of the substantially horizontal bottom plate 16 and the inclined support plate portion extending laterally on both the left and right sides of the upright plate 17 from above the upper end of the upright plate 17. 20 is formed, and in the grain conveyance path 18, a conveyance conveyor 7 that conveys the conveyed product supplied from the supply unit 2 is provided, and the conveyance conveyor 7 includes a supply unit 2 and a plurality of transport bodies 12 are provided at predetermined intervals in an endless chain 13 that is wound around so as to move between the discharge section 6 and each transport body 12 is made of a pair of endless chains 13 made of synthetic resin. It is formed integrally with both side links 25 and slides on the inclined support plate portion 20. The lower transport body portion 12B that connects the left and right upper transport body portions 12A is formed below the upper transport body portion 12A having the inclined slidable contact surface 21, and each transport body 12 and the grain transport are formed. Relative to the path 18, a grain transverse feed apparatus configured such that some unspecified transport bodies 12 of the plurality of transport bodies 12 are in contact with the inner surface of the grain transport path 18. Is.
In the present invention, at least one supply unit 2 is provided on one side of the machine casing 1 that is formed long in the transport direction, and at least one discharge unit 6 is provided on the other side of the machine casing 1. Between the right and left sides of the substantially horizontal bottom plate 16 and the inclined support plate portion extending laterally on both the left and right sides of the upright plate 17 from above the upper end of the upright plate 17. 20 is formed, and in the grain conveyance path 18, a conveyance conveyor 7 that conveys the conveyed product supplied from the supply unit 2 is provided, and the conveyance conveyor 7 includes a supply unit 2 and a plurality of transport bodies 12 are provided at predetermined intervals in an endless chain 13 that is wound around so as to move between the discharge section 6 and each transport body 12 is made of a pair of endless chains 13 made of synthetic resin. It is formed integrally with both side links 25 and slides on the inclined support plate portion 20. A lower transport body portion 12B that connects the left and right upper transport body portions 12A is formed below the upper transport body portion 12A having the inclined slidable contact surface 21. The surface 21 moves in a state where it is always in sliding contact with the upper surface of the inclined support plate portion 20, and the lower conveyance body portion 12 </ b> B of all the conveyance bodies 12 moves along the grain conveyance path 18 in the bottom plate 16 and the upright plate 17. A part of the unspecified transport bodies 12 among the plurality of transport bodies 12 is a transverse feed transport apparatus for grains configured to come into contact with the moving bottom plate 16 and the upright plate 17.
In the present invention, each of the transport bodies 12 is always smaller than the grain between the upright plate 17 and the bottom plate 16 of the grain transport path 18 when the lower transport body portions 12B of all the transport bodies 12 are stopped. All the lower conveyance body parts 12B move in the upright plate 17 and the bottom plate 16 during the grain conveyance, and the lower conveyance body parts 12B of some of the conveyance bodies 12 are located in the gap. This is a grain transverse feed device configured to slide in contact with the bottom plate 16.

In the first and second aspects of the invention, all the transport bodies 12 are supported by the support mechanism X, and noise is generated even when some unspecified transport bodies 12 are brought into contact with the inner surface of the grain transport path 18. Suppressing and preventing crushing of grains, it is possible to discharge powdery residue and facilitate maintenance work.
According to the second aspect of the present invention, it is possible to easily realize a configuration for discharging the granular residue.

An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a machine casing of a laterally feeding and conveying apparatus, which is formed long in the conveying direction. A supply unit 2 is provided at an upper position on one end side 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 part. Similarly, one or a plurality of discharge parts 6 may be provided in the intermediate part in addition to the discharge part 6 at the other end. The discharge unit 6 is provided with a shutter (not shown) that opens and closes the drop opening 5.
A transport conveyor 7 is provided in the machine casing 1 between the supply port (not shown) of the supply unit 2 and the discharge unit 6 at the other end. For convenience of explanation, assuming that the transport direction of the transport conveyor 7 is the front-rear direction, the transport conveyor 7 mounts the driven gear 8 with 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 unit 6 at the end. Between the driven gear 8 and the drive gear 10, an endless chain 13 provided with a plurality of conveying bodies 12 at predetermined intervals is wound around.
In this case, the endless chain 13 is hung between the driven gear 8 on the front side of the supply unit 2 and the drive gear 10 on the front side of the terminal drop 5, so that the conveying body 12 is on the front side (conveyance) of the supplying unit 2. The grain is transported by moving from the upper side of the direction) to the front side of the terminal drop 5.

The machine casing 1 is provided with a grain conveying path 18 having a bottom plate 16 and an upright plate 17 erected substantially vertically on the left and right sides of the bottom plate 16. It has a gap smaller than the grain with respect to the inner surface of the path 18 and is configured to move in a state where it is guided and supported directly by the support mechanism X without running sideways or offset.
The support mechanism X forms an inclined support plate portion 20 so as to spread laterally as it goes upward at the upper end of the upright plate 17, while each of the transport bodies 12 is formed of a synthetic resin plate member, The left and right inclined sliding contact surfaces 21 that are always in sliding contact with the upper surfaces of the left and right inclined supporting plate portions 20 are formed on the lower surface of the upper conveyance body portion 12A located above the inclined supporting plate portion 20.

That is, the transport body 12 always moves in a state where the left and right inclined support surfaces 21A of the upper transport body portion 12A slide in contact with the inclined support plate portion 20 of the machine casing 1 by its own weight. The transport body 12 is guided so as to be positioned at the center of the plate portion 20, and the moving transport body 12 is prevented from swinging left and right.
Further, the transport body 12 forms a lower transport body portion 12B below the upper transport body portion 12A so as to connect the left and right upper transport body portions 12A. It is formed in a rectangular shape that is horizontally long (sometimes vertically long according to the shape of the machine casing 1) according to the grain conveyance path 18 formed by the bottom plate 16 and the upright plate 17.

Accordingly, the transport body 12 moves in a state where the inclined sliding contact surface 21 is always in sliding contact with the upper surface of the tilt support plate portion 20, and the lower transport body portions 12 </ b> B of all the transport bodies 12 are connected to the bottom plate 16. It moves so that the grain conveyance path 18 in the standing board 17 may be moved, and some unspecified conveyance bodies 12 in the some conveyance body 12 may be comprised so that the bottom plate 16 and the standing board 17 may be in contact.
That is, the left and right side edges and the lower edge of the lower transport body portion 12B of all the transport bodies 12 always have a gap (0.1 to 1 mm) smaller than the grain with respect to the bottom plate 16 and the upright plate 17. It is configured to be movable and to allow contact movement of a part of the transport bodies 12.

  Conventionally, since the carrier 12 hits the inner surface of the machine casing 1 due to the lateral shake or the offset movement, a considerably large noise is generated and the carrier 12 is not specially supported. Therefore, the intermediate portion usually hangs down. The gap between the inner surface of the housing 1 and the transport body 12 is not constant, and a minimum gap of 1 cm or more is provided so as not to contact at all. However, in the present application, the transport body 12 is supported by the support mechanism X. The lower transport body portion 12B and the bottom plate 16 are moved so as to allow the lower transport body portions 12B of some of the transport bodies 12 to move in a so-called sliding contact state. Further, the upright plate 17 is relatively positioned so that not only the grains but also the granular residue can be removed and discharged without providing a so-called scraper.

In other words, the transport body 12 is in a state in which the inclined sliding contact surface 21 of the left and right upper transport body portion 12A is supported in sliding contact with the inclined support plate portion 20 of the machine casing 1, and the lower transport body portion 12B is the bottom plate. 16 and the upright plate 17 are moved so as to be partly in contact with each other so that all the lower transfer body portions 12B are located in the grain transfer path 18 between the bottom plate 16 and the upright plate 17 at the time of mounting. Thus, when the predetermined clearance S is provided and transported, the lower transport body 12B of a part of the transport bodies 12 is configured to contact the bottom plate 16 and the upright plate 17.
In other words, a part of the transport bodies 12 does not mean a specific transport body 12 but means a predetermined number of transport bodies 12 among a large number of transport bodies 12 that are being transported. Due to the existence of manufacturing tolerance and assembly tolerances of the grain transport path 18, the lower transport body parts 12 </ b> B of all the transport bodies 12 are located in the grain transport path 18 at the time of installation, but when the transport movement is started The inner surface of the grain conveyance path 18 is contacted for reasons such as vibration.
Therefore, since the specific carrier 12 is not always in contact with the inner surface of the specific grain conveyance path 18, when tested, most of the carriers 12 have contact marks at different portions. Therefore, the generation of noise is suppressed and the durability is not deteriorated as compared with the case where all the transport bodies 12 are always contacted.

Thus, the depth of the upright plate 17 and the width of the bottom plate 16 are arbitrary, and the inclined support plate portion 20 and the inclined support plate portion 20 so that the carrier 12 moves in the center according to the depth of the upright plate 17 and the width of the bottom plate 16. The inclination angle of the inclined sliding contact surface 21 may be set.
Thus, the endless chain 13 is formed into an endless shape by detachably connecting both side links 25 in the front-rear direction formed of a synthetic resin by a locking shaft member 26, and left and right sides of a predetermined one of the side links 25. The transport body 12 is integrally formed so as to protrude in the crossing direction with respect to the traveling direction.
In this case, the transport body 12 has an upper transport body portion 12A projecting laterally from each of the pair of left and right side links 25 of the endless chain 13, and the left and right upper transport body portions 12A are connected to the left and right lower transport body portions 12B. Therefore, a part of the lower transport body 12B is located below the both side links 25.

The left and right side links 25 are positioned with a roller 31 through which the locking shaft member 26 is inserted therebetween, and the end of the locking shaft member 26 is detachably attached by a fastening tool 32 such as a split pin. 33 is a washer.
In addition, since the both side links 25 are connected to each other by the locking shaft member 26 and are formed in an endless shape, when the fastening device 32 is removed without using a special dedicated tool, a large number of the side link 25 You can remove any.
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 can be easily adjusted, which is preferable.

  Therefore, the lower edge 24 of the transport body is formed on the inclined surface 34 that is lowest in the center and becomes higher as it reaches the front and rear sides in the traveling direction. Therefore, when the transport body lower edge 24 comes into contact with the bottom plate 16, line contact is sufficient instead of surface contact by the entire plate thickness surface of the transport body 12. Since the inclined surfaces 34 are formed on both the front and rear sides in the traveling direction, the transport body 12 is moved in either the forward or reverse direction (front and back) to move the grains to the supply unit 2 and the discharge unit 6. It becomes possible to improve versatility (for example, the supply unit 2 is provided in the center, the discharge units 6 are provided at both ends, or the supply units 2 and the discharge units 6 are alternately arranged to discharge each supply unit 2 It is transported between the parts 6).

Moreover, when the cross-sectional shape of the left and right inclined sliding contact surfaces 21 is formed in a predetermined arc shape, the biting of grains and the generation of abnormal noise are suppressed or prevented (FIG. 9).
In addition, when both the side links 25 constituting the endless chain 13 and the upper surface of the transport body 12 are formed on the grain dropping surface 35 whose cross section is inclined so as to gradually become lower with a triangular apex interposed therebetween, the both side links 25 Moreover, it is possible to prevent the grain from being placed on the upper surface of the carrier 12 and becoming a residue, which is preferable.
Reference numeral 36 denotes a support roller for supporting the upward endless chain 13 provided in the machine casing 1, and 37 denotes a floating prevention body for preventing the endless chain 13 from floating, and a plurality of them are provided at desired positions. Reference numeral 40 denotes a shutter for stopping the fall of the grain from the discharge unit 6. Although not shown, the support mechanism X is provided above the shutter 40. Reference numeral 43 denotes a frame for mounting the shutter 40.

(Operation of Example)
When the motor is energized, the drive gear 10 rotates, and the drive gear 10 rotates the endless chain 13 to move the transport body 12 from the supply unit 2 to the discharge unit 6.
In the machine casing 1, a grain conveyance path 18 having a bottom plate 16 and a substantially vertical upright plate 17 on the left and right sides of the bottom plate 16 is provided, and each conveyance body 12 is directly guided and supported by a support mechanism X. Since it is configured to move, all the transport bodies 12 are moved by the support mechanism X in the center of the grain transport path 18 without running sideways or offset.
Thus, the support mechanism X moves the grain conveyance path 18 sideways as it reaches the upper side of the smooth bottom plate 16, the substantially vertical upright plate 17 on the left and right sides of the bottom plate 16, and the upper end of the upright plate 17. The left and right inclined slidable contact surfaces 21 are always slidably in contact with the upper surfaces of the left and right inclined supported plate portions 20 by a synthetic resin plate member. Therefore, the left and right inclined sliding contact surfaces 21 move while being in sliding contact with the inclined support plate portion 20 of the machine casing 1 due to the weight of the conveying body 12. The lower body edge 24 moves with a gap smaller than the grain from the upper surface of the bottom plate 16.

In this case, if the gap between the upper surface of the bottom plate 16 and the lower edge 24 of the transport body 12 is larger than the grain, the grains remaining on the bottom plate 16 and the grains that are transported by the transport body 12 are moved up and down. There will be two layers, and the grain at the boundary between the upper and lower layers will be rubbed and damaged, but the gap between the upper surface of the bottom plate 16 and the lower edge 24 of the transport body 12 is the grain. Because the gap is smaller than the grain, the transport body 12 transports the whole grain distributed in the vertical direction, and prevents damage due to rubbing between the grains.
Therefore, if the inclined support plate portion 20 is provided above the upright plate 17 of the grain conveyance path 18 and the inclined sliding contact surface 21 that matches the inclined support plate portion 20 is provided on the conveying body 12, the support mechanism X is provided. It can be configured, can be made a simple configuration, and the cost can be reduced.

In addition, since the left and right inclined sliding contact surfaces 21 move while being in sliding contact with the inclined support plate portion 20, the conveyance body 12 is always guided to be positioned at the center of the left and right inclined support plate portions 20. Even if a force that swings to the left or right is generated in the transport body 12, the force that causes the lateral swing is a reaction force that the inclined sliding contact surface 21 hits the inclined support plate portion 20, and the transport body 12. The transport body 12 is always guided and supported so as to move in the center of the left and right grain transport paths 18.
Therefore, since the support mechanism X is configured to guide in the vertical direction, the support mechanism X also has an effect of guiding and supporting in the width direction (left and right direction), so that the gap between the lower side edge 22 of the carrier 12 and the upright plate 17 is also a grain. The gap can be set smaller than the grain, which is more rational and lowers the cost.

Thus, the inclined support plate portion 20 has an effect of guiding the grains into the grain conveyance path 18 between the upright plates 17 when the conveyance amount is reduced. Since the conveying body 12 above the contact surface 21 moves, and the lower part of the inclined support plate part 20 can convey the grain between the left and right upright plates 17 without retreating to the side, the inclined support plate part 20. Does not lower the conveying efficiency while acting to induce in the grain conveying path 18 between the upright plates 17.
Therefore, even if there is a grain above the upper surface of the transport body 12, the tilted sliding contact surface 21 of the transport body 12 is brought into sliding contact with the tilted support plate part 20. The part of the carrier 12 above the inclined sliding contact surface 21 acts on the grain, and the upper grain moves while resting on the grain moving like a conveyor belt in the lower part, In combination with the above-described actions, the sheet is conveyed in a vertically integrated manner, so that the occurrence of grain damage between the upper and lower sides is minimized while always ensuring a predetermined conveyance efficiency regardless of the amount of conveyance.
In addition, if the left and right widths of the inclined support plate portion 20 and the inclined sliding contact surface 21 are set to the minimum area necessary for guiding the conveyance body 12, uneven conveyance between the upper and lower sides can be further prevented, and the conveyance efficiency is improved. Is preferred.

Thus, the transport body 12 is supported by the support mechanism X and moves in a state in which the inclined sliding contact surface 21 is always in sliding contact with the upper surface of the inclined support plate portion 20, and all the transport bodies 12 are moved to the bottom plate 16. And the grain transport path 18 in the upright plate 17 is moved, and a part of the plurality of transport bodies 12 is configured to come into contact with the moving bottom plate 16 and the upright plate 17, so that the transport work is about to end. As a result, a part of the plurality of conveying bodies 12 comes into contact with the bottom plate 16 and the upright plate 17 due to vibration during movement, so that the residue is removed and discharged without providing a so-called scraper.
In this case, a part of the plurality of transport bodies 12 comes into contact with the moving bottom plate 16 and the upright plate 17, so that not only grains but also powdery residues are discharged.
That is, in the first place, since the conveying body 12 hits the inner surface of the machine casing 1 due to the lateral shake or the offset movement, a considerably large noise is generated. Therefore, a gap of 1 cm or more is provided so as not to contact the inner surface of the machine casing 1 at all. Since it is vacant, a scraper is necessary, and even a scraper moves in an air-suspended state on an endless chain, so that it does not necessarily contact the bottom plate 16 and remains.

However, in the present application, the lower transport body portion is supported so that the transport body 12 is supported by the support mechanism X and the lower transport body portions 12B of some of the transport bodies 12 are allowed to move in a so-called sliding contact state. Since 12B and the bottom plate 16 and the upright plate 17 are relatively positioned, not only the so-called scraper but also the removal of not only the grains but also the particulate residue can be efficiently discharged.
That is, even a scraper moves in an endlessly suspended state in a suspended state, so that it may float and a residue is generated. However, in the present application, an unspecified transport body 12 among a plurality of transport bodies 12 is a bottom plate 16. Alternatively, since it comes into contact with the upright plate 17, it efficiently removes and discharges not only grains but also granular residues.

Thus, the left and right upper transport body portions 12A are connected to each other below the both side links 25 by the left and right lower transport body portions 12B, and a part of the lower transport body portion 12B is positioned below the both side links 25. Therefore, the removal and discharge of the powdery residue on the bottom plate 16 is ensured.
Moreover, since the lower edge of not all the conveyance bodies 12 is made to contact the bottom board 16, suppression of a noise and grain damage and discharge | emission of a residue are made compatible.
