[Detailed description of the invention] (Industrial application field) This invention is a two-stage horizontal chain conveyor that has a floating chain that prevents the chain from floating due to the resistance of grains, etc. This relates to a prevention device. (Prior art) Conventionally, a lifting prevention device for a conveying chain in this type of lateral chain conveyor was developed in the 1980s.
There is an idea described in Publication No. 173509. (Problem to be solved by the invention) The lifting prevention device for the conveyance chain in the conventional cross-feeding chain conveyor described above consists of a thin plate placed on the lower part of the conveyance chain, facing the rollers thereof, and facing in the direction of transport of grains, etc. A floating prevention piece having a shape is provided, and the floating prevention piece receives the roller of the lower piece of the conveyance chain and prevents the lower piece from floating. By the way, in the conveyance chain of a two-stage horizontal chain conveyor, in order to transfer all of the grains, etc. without damaging them and without leaving them in the machine casing, the conveyor chain has almost the entire machine casing passing under it. When providing auxiliary blades with an inner width, the auxiliary blades passing under the upper and lower pieces of the conveyance chain are on opposite sides of the conveyance chain, inside and outside. Therefore, the auxiliary blades of the conveyance chain must be provided on both the inside and outside surfaces of the conveyance chain, and the auxiliary blades are also located on the lower side of the conveyance chain. There is a problem in that a float prevention device for a conveyance chain that catches the rollers of the conveyance chain by a float prevention piece cannot be used. (Means for Solving the Problem) Therefore, this invention provides a partition wall 8 along the longitudinal direction of the machine case 1 which is long in the left and right direction in the vertically intermediate part thereof, so that the upper and lower passages inside the machine case 1 are separated. The upper part of the conveying chain 3 with blades 2 on both sides is placed on the partition wall 8, and the lower part is placed on the machine casing. In a two-stage transverse chain conveyor that is arranged in contact with the bottom plate 6 of the conveyor chain 1 , in order to prevent the conveyor chain 3 from floating and solve the above problem, the side edges of the blades 2 on both sides of the conveyor chain 3 are A fitting recess 4 is formed in the intermediate portion, and floating prevention rails 5a and 5b are provided along the longitudinal direction on the inner surface of the front and rear walls of the machine casing 1 , appropriately above the bottom plate 6 and the partition wall 8 of the machine casing 1. The fitting recesses 4 on both sides of the upper and lower pieces of the conveyance chain 3 are loosely fitted into the upper and lower front and rear lifting prevention rails 5ro and 5a, respectively, and the upper piece of the conveyance chain 3 is placed on the partition wall 8. When the lower pieces come into contact with the bottom plate 6 of the machine casing 1 , a gap 7 is formed between the fitting recess 4 of the conveying chain 3 and the upper and lower lifting prevention rails 5ro or 5i. (Function) Using the lower passage b in the machine casing 1 , the transport chain 3
When the lower piece of the conveyor chain 3 moves along the bottom plate 6 to transfer grains, etc., the blade 2 of the conveyor chain 3
Therefore, it rotates without hitting the rail 5i and performs a transfer action. During the transfer, when the lower part of the conveyance chain 3 rises to some extent due to the resistance of the grains, the lower edge of the recess 4 of the blade 2 of the conveyance chain 3 hits the rail 5a. The conveying chain 3 rotates while sliding in contact with the conveying chain 3, and the lower part of the conveying chain 3 is prevented from floating, thereby achieving a conveying action. On the other hand, when the upper passage a in the machine casing 1 is used and the upper part of the conveyance chain 3 advances along the partition wall 8 to transfer grains, etc., the same operation as described above occurs, and the rail 5ro The upper part of the conveyance chain 3 is prevented from floating, thereby performing a conveying action. (Example) To explain the structure of one embodiment of this invention shown in the drawings, 1 is a horizontally long machine casing of a two-stage traversal chain conveyor, with the middle part in the vertical direction excluding both sides. A partition wall 8 is provided along the longitudinal direction to form upper and lower passages a and b within the machine casing 1 . 9
11 is a drive sprocket installed by a drive shaft 10 in the lower part of one side in the machine casing 1 , and 11 is a driven sprocket installed in the lower part of the other side in the machine casing 1 by a driven shaft 12. A radial auxiliary blade fitting groove 14 is provided at the center between the roller engaging recesses 13. Reference numeral 3 designates a conveying chain, in which blades 2 are provided at the outer intermediate portions of every other link on both sides of the chain body 15, and elastic auxiliary blade plates 16 and 17 made of urethane rubber or the like are sequentially attached to the 2 parts of the blades. They are fitted alternately from the outside and the inside and are fixed to the blades 2 on both sides,
The auxiliary blade plates 16 and 17 are made to protrude outward or inward on both sides from the chain body with the blade 2, and the auxiliary blade plate 16 or 17 is made to protrude outward or inward from the chain body with the blade 2, and from the blade 2 on both sides thereof.
A fitting recess 4 is formed in the middle of both side edges to constitute a conveyance chain 3 . 5a and 5b are floating prevention rails fixed to the inner surfaces of the front and rear walls of the machine casing 1 along the bottom plate 6 and partition wall 8 of the machine casing 1 , the upper surfaces of which are inclined inwardly and downwardly; At both ends, inclined guide surfaces 18 are formed with both upper and lower surfaces inclined toward opposite sides. Therefore, the inner auxiliary blade plate 17 of the conveyance chain 3 is inserted into the auxiliary blade plate insertion groove 14 of the sprockets 9 and 11, and the fitting recesses 4 on both sides of the lower piece and the upper piece are used to prevent front and rear floating. rail 5i, 5
The conveyor chain 3 is loosely fitted into the sprockets 9 and 11, respectively, and the outer auxiliary blade plate 16 of the conveyor chain 3 is placed on the bottom plate 6, and the inner auxiliary blade plate 17 is placed on the partition wall 8. The fitting recess 4 and the floating prevention rail 5 are arranged in contact with each other, and the fitting recess 4 and the floating prevention rail 5
A gap 7 is formed between A and 5 B, and the auxiliary blade plate 1
6 and 17 so that they almost fill the entire inner width of the machine casing 1 . Reference numeral 19 denotes a one-side supply gutter, the lower end of which is connected to one side opening of the top plate of passage a. 20 is the other side supply gutter,
The tips of the lower bifurcated portions are respectively connected to the upper openings on the other side of the front and rear walls of the passage b. 21 and 22 are the bottom plate 6
These are discharge ports formed on the other side and on one side, respectively. Reference numerals 23 and 24 denote detent plates stretched inside the machine casing 1 on one side of the one-side supply gutter 19 and on the other side of the other-side supply gutter 20, respectively. Next, its effect will be explained. When power is transmitted to the drive shaft 10, the conveyor chain 3 is driven by the sprocket 9, and the blades 2 are prevented from hitting the rails 5a and 5ro due to the gap 7, and the inner auxiliary blade plate 17 is As shown in Figure 1, sprocket 9
While going in and out of the grooves 14 of 11 and 11, the outer auxiliary blade plate 16 of the lower piece slides on the bottom plate 6, and the inner auxiliary blade plate 17 of the upper piece slides on the partition wall 8. Rotate in the direction of the arrow in FIG. Therefore, for example, when grains are fed into (a) the supply gutter 19, the grains fall onto one side of the partition wall 8, and the blades 2 with the inner auxiliary blades 17 of the conveyance chain 3 are used to transfer the grains to the partition wall. The liquid does not remain on the machine casing 8, but is transferred to the other side within the passage a, and is discharged from the discharge port 21 to the lower part of the other side of the machine casing 1 . (b) When the grains are fed into the supply gutter 20, they pass through the feed gutter 20, fall from the front and rear openings onto the other side of the bottom plate 6, and are transported by the blades 2 with the outer auxiliary blades 16 of the conveyance chain 3 . The liquid does not remain on the bottom plate 6, but is transferred to one side in the passage b, and is discharged from the discharge port 22 to the lower side of the machine casing 1 . (c) When feeding into supply gutter 19 and 20 at the same time,
The actions of (a) and (b) above are performed simultaneously and the supply gutter 19
The grains fed into the supply gutter 20 are discharged simultaneously from the discharge port 21 to the lower side of the machine casing 1 on the other side, and the grains fed into the supply gutter 20 are discharged from the discharge port 22 to the lower side of the machine casing 1 . (d) During the transfer, if the lower part of the conveying chain 3 rises to some extent due to the resistance of the grains, the lower edge of the recess 4 of the lower part will come into contact with the rail 5a. When the upper piece slides into contact and floats to a certain extent, the lower edge of the recess 4 of the upper piece hits the rail 5 and the conveying chain 3 rotates while sliding in contact with it . The lower piece and the upper piece are prevented from floating and perform a grain transporting action. Note that the supply gutter 19 may be connected to an opening provided in the upper front wall of the passage a instead of the opening in the top plate of the passage a. It should be noted that the same effect as described above also occurs when other grains or the like are transferred instead of the above-mentioned grains. Further, even if this invention is applied to a two-stage horizontal chain conveyor provided with a conveyance chain to which the above-mentioned auxiliary vanes 16 and 17 are not attached, the same effect as described above will occur. (Effects of the invention) The device for preventing floating of a conveying chain in a two-stage lateral chain conveyor of this invention has the following remarkable effects. (1) Since a gap is formed between the fitting recess of the conveyor chain blade and the upper and lower floating prevention rails, the conveyor chain moves along the bottom plate and partition wall of the machine casing to remove grains, etc. When transferring, the conveyance chain rotates independently of the anti-float rail without hitting the anti-float rail to perform the transfer action. (2) If the conveyance chain rises to some extent due to the resistance of the grains during the transfer of grains, etc. in either the upper or lower passages within the machine casing, the recesses of the blades of the conveyor chain may The conveying chain rotates while sliding in contact with the anti-floating rail, completely preventing the conveying chain from floating, allowing accurate and quick conveying action to improve work efficiency and improve grain Grain damage is prevented. (3) Anti-float rails are installed along the longitudinal direction of the front and rear walls of the upper and lower passages inside the machine casing.
In the upper and lower passages within the machine casing, the lifting of the conveying chain is evenly prevented over all parts of the conveying chain that perform a conveying action. (4) Even in a two-stage cross-feed chain conveyor that has auxiliary vanes on both the inside and outside surfaces of the conveyor chain, floating prevention rails can prevent the conveyor chain from floating, regardless of the auxiliary vanes. It has great versatility. (5) Since the anti-float rails are located along the longitudinal direction of the inner surfaces of the front and rear walls of the upper and lower passages within the machine casing, they do not interfere with the movement of grains, etc.
