Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rocking device for a packet elevator of a mechanical landing machine for unloading granular materials such as grain.

Conventionally, in this type of mechanical landing machine, grain stored in a ship's hold, for example, is scraped off by a vertical baffle 1~''-lever and transferred upwards, and then, for example, by a belt t~'' elevator.
: The ship was being transported horizontally and unloading work was being carried out.

At that time, the size of the granular material and the size of the mechanical landing machine were determined.
The vessel is landed by the running and traversing of the bucket, but the vertical bucket is connected to the vertical bucket insertion port, which extends laterally to the ship. A slope is formed at the same angle of repose of a certain granule and remains.

Therefore, in the past, the particulate matter remaining in the corner of the hold was manually piled up to near 1 vertical bag u-(
They were unloading. In addition, we are trying to use mechanical force to remove the granules in the corners of the ship to carry out the leaf-lifting process.
There is a drawback that the vertical bafflers 1~ are too close to the insertion port to avoid damaging the insertion port or the vertical packet.

FIG. 1 shows an example of such a conventional landing aircraft.

In Fig. 1', the land machine, indicated by the symbol Δ as a whole, is a running platform 2 that can run on a pair of rails 1.1-t laid on the quay E.
The carriage 2 has a post 3 mounted thereon so that it can rotate about its vertical axis. An arm 5 is pivotally mounted near the top of the post 3 at a pivot point 4 so as to be rotatable in the vertical direction. Further, near the lower end of the post 3, a boom 8 supporting a belt conveyor 7 at a pivot point 6 is pivotally mounted. Furthermore, a support arm 11 is pivotally attached to the tips of the arm 5 and the boom 8 at respective pivot points 9.10, and a vertical packet elevator 13 is attached to a support part 12 formed integrally with the support arm 11. It is provided so as to be freely rotatable with a conveyor V-swivel mounting 14. boss i
~ 3, arm 5, boom 8, and support arm 11 constitute a so-called four-frame link J, a four-section rotating chain.
A stay 41 is numbered in the middle. The arm 5 is configured to rotate up and down about the pivot point 4 by operating the operating cylinder 16. In the figure, 17 is the balance way 1-.

Therefore, by the operation of the actuating cylinder 16, the vertical buff 1 to the elevator attached to the arm 5 can move up and down between the upper position 13a shown by the dotted chain line in the figure and the lower position (1 shown by the solid line in Fig. 1). It looks like this.

Therefore, the accumulated material stored in the lead pipe 20 of the ship is scooped up by the vertical packet elevator 13 and transferred upward,
The accumulated material that has arrived is rotated through the shoe 1-45.
744, and is further transferred from the conveyor V7 on the boom 8 through the chute 46 to the hopper 1 provided at the center of the post 3.
8, the conveyor belt 2 is sent to the second conveyor 119 installed on the running platform 2, and then from the end 40 of the conveyor 19 to the fixed conveyor 47 installed on the quay E.

During these landing operations, the rotation of the post 3, the rotation of the arm 5
The vertical rotation of the vertical packet elevator, the rotation of the vertical packet elevator, etc. are all operated from the control unit 1 to the roll room C installed on the boom 8. The reason for this is that the position of stored items inside the ship changes and the ship moves up and down due to the ebb and flow of the tide.

During landing work, granular materials W such as grains are unloaded by the running and traversing of the unloader, but the cargo hold 20 is
Buff 1 - Insertion port 1 of elevator 13, that is hatch 21
Therefore, the particulate matter W in the partition of the hold on the side of the hatch 21 forms a slope 22 at its angle of repose and remains. Therefore, in the past, the particulate matter W remaining in the partition of the ship 620 had to be brought close to the packet elevator 13 by human labor or the like. Also, if possible, remove particulate matter W from the space between the holds.
If the landing work is carried out using mechanical power, the packet elevator 13 will be too close to the hatch 21.
This has the drawback of damaging the packet elevator 13.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a rocking device for a lift of a landing machine that can unload granular materials to a space in a cargo hold by mechanical force without manual force.

According to the present invention, in a rocking device for a packet elevator of a landing machine for unloading granular materials such as grain, a support arm is provided which is integrated with a support portion of the packet elevator.
One end of the arm is pivoted to one part of the support arm, and a boom is pivoted to the lower part of the support arm A, and the other ends of the arm and boom are pivoted to the upper and lower parts of the other support arms, respectively. , A is pivotally connected to the post, and a fixed portion of the post and an intermediate portion of the separate support arm are pivotally connected via a swinging means.

Therefore, if another support arm constituting the four-bar link is tilted from the perpendicular direction to the swinging means, the support arm of the back elevator will also tilt, causing the back elevator to swing. As a result, the unloading efficiency is greatly improved.

In carrying out the present invention, it is preferable to use a hydraulic cylinder device as the swinging means.

Hereinafter, embodiments of the present invention will be described in detail with reference to FIG. 2 and subsequent figures. In these drawings, parts corresponding to those in FIG. 1 are designated by the same reference numerals! 1′! Omit double explanations.

In Figures 2 and 3, the boom 8 is connected to the support part 1.
It is pivoted to the post 3 at a pivot point 6 at the bottom of the post 3 on the opposite side of the post 3, and another support arm 25 is pivoted at the pivot point 6 and is installed at a slightly higher point than the middle. a pivot point 26 fixed to the fixed portion 42 of the post 33;
A swinging means °'IJ, that is, a one-cylinder oil cylinder device 28 is connected between the two.

According to the invention, therefore, arm 5, boom 8, support arm 11 and further support arm 25 form a so-called four-bar link. to this hydraulic cylinder device 28:
This normally places another support arm 25 in a vertical position,
Thus, as explained in FIG. 1, the vertical movement of the lever 13 can be performed.

J) Another balance weight 29 is provided above the tip of another support arm 25.

When operating the packet elevator 13, start at 1lrt.
3, when the hydraulic cylinder arrangement 28 is retracted, the further support arm 25 moves to the position 25C and the packet elevator 13 tilts to the position n 13 G. On the other hand, when the hydraulic cylinder device 28 is extended, another support arm 25I; moves to the L position FT25d, the baffle 1-elevator 13 moves to the position f(1-3(1), and another balance way 1-29 moves to this position. This is to balance the situation.

Figures 4 to 6 show Bakut 21-lever 13.
A device is shown that prevents the bucket 30 from coming into contact with the casing 32 due to the belt 31 sagging due to the weight of the baffles 1 to 30 during the above-mentioned swinging. ! In other words, packet 30 is divided into multiple pieces, ie, MA 0113 pieces in the drawing? J30. Divided into I, 30b, 30C and J
3, and the intermediate portions 30d and 30e are provided with ri'-sings 3.
A plurality of slack suppressors 2 are rotatably supported via a bearing 33 and a shaft 34, and a relief ring 35 is provided so as to come into contact with them.

Next, the action will be explained.

As shown in FIG. Chain line 13d
As shown in the hydraulic cylinder device i? ff128 is extended, and another support arm 25 is tilted in the direction around time t1. Then, the boom 5 moves parallel to the right, and the I support arm 11 similarly tilts clockwise, (as a result, the packet elevator 1
3 is the position 13d k:ilJ<. On the other hand, when the hydraulic cylinder device 28 is contracted, the packet elevator 13 is tilted to the opposite side. Therefore, the above-mentioned residual particulate matter at the left and right corners can be transferred manually, and the landing efficiency is greatly improved. Note that even if the belt 31 sag due to the weight of the packet 30 during this swinging, the belt 31 is suppressed by the sag suppressing wheels 35 at the packet dividing portions 30d and 30e, so that the baffler]
30 and casing 32 do not come into contact, and as a result,
! Generation of A sound and damage to the packet 3° are prevented.

As explained above, according to the present invention, the packet elevator can be swung by vertically tilting another support arm 25 that constitutes a four-bar link! Since the rocking means is provided, it is possible to unload granular materials up to the bulkhead of the ship without relying on human power, and as a result, the unloading efficiency is greatly improved.
