バケツトエレベーターに関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a bucket elevator for excavating and transporting bulk loads using buckets supported on an endlessly driven chain.

The continuous unloader bucket elevator is
As shown in Fig. 1, a chain sprocket 3 rotated by a motor, a driven chain sprocket 4,
5 through the chain 1, the chain 1 is stretched endlessly, and the bucket 2 is attached to the chain 1. This bucket elevator uses a chain 1 that is driven endlessly to move bulk cargo 7 inside the ship.
It has the function of excavating and lifting the load upward with a bucket 2 attached to the bucket, preventing the load in the bucket 2 from falling into a chute 6, and transferring the load to a conveyor 9 via a hopper 8.

れ、特に上下の揺れにうまくバケツ２が追従でき
ずにチエン１にバケツ２から直接大きな衝撃を受
けやすく、チエン１の変形が大きくなる。 Conventionally, the chain 1 and the bucket 2 are attached by fixing a bracket 10 fixed to the side surface of the bucket 2 to the chain 1 with bolts 10a, as shown in FIGS. 2 and 3. For this reason, when the bucket 2 excavates the load, the bucket 2 receives an excavation resistance force F, and changes from the state shown in FIG. 4 to the state shown in FIG. 5. When this happens, the chain 1 changes from a straight line to a zigzag shape and moves like an inchworm. Therefore, the scooping angle α becomes a large angle β as shown in FIG. For this reason, the efficiency with which the bucket 2 scoops out the load deteriorates. Furthermore, high-speed cargo handling cannot be performed due to deformation of the chain 1. In addition, because the bucket 2 is fixed to the chain 1, the bucket 2 cannot properly follow the unevenness of the excavation surface or the shaking of the ship, especially the vertical shaking, and the chain 1 is easily subject to a large impact directly from the bucket 2. The deformation of chain 1 increases.

が悪化するし、高速荷役が行えない。 As a conventional example of preventing the deformation of the chain 1 and escaping the force of pushing up against the bucket 2 due to the vertical movement of the ship, there is an example in which the chain 1 and the bucket 2 are connected and connected with the buckets 2 using flexible members. . In this example, when an overload is applied to the bucket 2, the flexible member bends and the bucket 2 escapes from the overload. However, according to this example, the bucket 2 tends to swing unnecessarily in all directions, resulting in poor work efficiency and high-speed cargo handling.

The gist of the present invention is, as a basic configuration, in a bucket elevator that transports a plurality of buckets using an endlessly driven and supported chain, a highly rigid link is rotatably attached to the chain in the longitudinal direction of the chain, A highly rigid first link member is rotatably attached to the chain in a longitudinal direction of the chain at a position away from the link, and the rigid first link member is rotatably attached to the first link member in the same direction as the first link member. A second link member with a high angle is pivoted, and an elastic body is installed between the first link member and the second link member in a state that controls the posture of each link member in a straight line. The second link member and the link are pivoted to the bucket so that the relationship between each link member and the link is in an inverted V-shape toward the bucket. Equipped with a bucket support device for a bucket elevator, each link supports the bucket so that it escapes in a certain direction, and an elastic body cushions the impact transmitted to the chain, while maintaining the bucket's posture as constant as possible to improve cargo handling efficiency. It is on the verge of improvement.

バケツ１６に連結する状態となる。 The installation relationship between the chain 15 and the bucket 16 is as follows:
As shown in Figure 6. That is, the chain 15 has a short chain pitch, and the brackets 17 and 18 are fixed at intervals of several pitches. A link 12 is connected to one bracket 17 by a shaft 19 so as to be freely rotatable in the direction of arrow A, that is, in the longitudinal direction of the chain 15. A first link member 20 is connected to the other bracket 18 by a shaft 21 so as to be freely rotatable in the direction of arrow A. A second link member 22 is connected to the first link member 20 by a shaft 23 so as to be freely rotatable in the direction of arrow A. Both the link 12 and each link member 20, 22 are made of metal and have high rigidity. The rotating end of the link 12 is rotatably attached to one end side of the upper frame 28 of the bucket 16 with a shaft 24. The rotating end of the second link member 22 is attached to the other end of the upper frame 28 of the bucket 16 with a shaft 25. The shaft 23 is fitted with intermediate loop portions of springs 26 and 27, which are in the state shown in FIG. Protrusions 29, 30,
It is connected and fixed to parts 31 and 32. Since these springs 26 and 27 constantly generate a force to return to the free state due to their elastic force, each link member 20 and 22 is in a straight line in the free state. The distance between the shaft 19 and the shaft 21 is the same as that of the shaft 24.
Since it is set wider than the distance between the and shaft 25,
The linear link members 20 and 22 and the link 12 are connected to the bucket 16 in an inverted V-shaped arrangement toward the bucket 16.

Since the bucket 16 is supported by the bucket 2, there is an advantage that the bucket 16 is essentially difficult to shake. For this reason, the chain 15 can be operated at high speed to improve cargo handling efficiency.

ない。 Drive the chain 15 in the B direction to transfer the load to the bucket 16
When the bucket 16 receives excavation resistance force F H and thrust force F V due to the vertical movement of a loaded ship while excavating, the link 12 rotates upward around the shaft 19, and each link member 20, 22 is bent around the shaft 23, and the bucket 16 escapes upward, resulting in the state shown by the chain line in FIG. Therefore, the impact applied to the bucket 16 is not transmitted to the chain 15, and the chain 15 does not deform. Therefore, the chain 15 can be operated at high speed. In addition, the appropriate digging resistance force F H
The rake angle of the bucket 16 in the free state is determined so that the rake angle α of the bucket 16 is appropriate when receiving the load. This determination can be achieved by adjusting the lengths of the link members 20, 22 and the link 12 and the mounting position with respect to the bucket 16. It can also be determined by changing the shape of the bucket 16. Furthermore, in this embodiment, the movement of the link 12 and each link member 20, 22 causes the shafts 24 and 25, that is, the front and rear portions of the bucket 16, to simultaneously lift upward, so that the bucket 16 is fixed to the chain 15. Compared to this, the change in the scooping angle α is small and the scooping efficiency does not decrease significantly. Furthermore, since the springs 26 and 27 are bent when the link members 20 and 22 are bent around the shaft 23, the bucket 1
The impact force that is about to be transmitted from 6 to chain 15 is converted into a force that bends springs 26 and 27, and
It becomes difficult to convey the information to 5. Therefore, this spring 26,
27 relieves the force that tends to deform the chain 15. Furthermore, each link member 20,
The bending direction of 22 is the longitudinal direction of the chain 15, and each link member 20, 22 and the link 12 have rigidity and do not sway in a direction perpendicular to the chain 15 (perpendicular to the plane of the paper in FIG. 5). Because it is hard, the bucket 16 will not escape from below the chain 15 to the side and the work efficiency will not decrease.

ツ１６を上方へ引き上げる途中でバケツ１６のふ
らつきはなく高速で荷役できる。 When the digging resistance force and thrusting force applied to the bucket 16 disappear, each link member 20, 22 returns to a straight line due to the restoring force of the springs 26, 27, and the bucket 16 is moved through the chain 15 with the load still in the bucket.
It can be supported in a certain posture against Therefore, the bucket 16 does not wobble while being pulled upward, and cargo can be handled at high speed.

The spring action of 27 establishes a spring suspension structure for the chain of the bucket 16, allowing the bucket 16 to actively follow the irregularities of the excavation surface, allowing for efficient work.

Bucket 1 due to excavation resistance because it is ahead of the point
The moment that tries to rotate the chain 15 is in the direction of decreasing, and when the digging resistance is the same, the force transmitted to the chain 15 is smaller than in the conventional example in which the bucket 16 is directly connected to the chain 15.

As described above, according to the present invention, the bucket does not swing unnecessarily, and the movement of the link and the elastic body prevent excessive load from being transmitted to the chain, thereby eliminating deformation of the chain. In addition, when the bucket escapes due to overload, both the front and rear parts of the bucket move toward the chain, so the scooping angle of the bucket does not change significantly, so the cargo handling efficiency of the bucket elevator is improved. The effect of improving this can be obtained.
