Abstract

PURPOSE: To move a mounted bucket upward or downward to discharge articles in it by providing a device to rotate the bucket or a support to it about a center of a part where it is supported by chains or ropes at an upper or lower part. CONSTITUTION: A bucket 2 is freely rotatable relative to chains or ropes 1 on both sides, and when the chains or ropes 1 are moved, the gravity center of the bucket 2 is positioned under a supported position, so a supported angle of the bucket 2 is constant. After the bucket 2 is moved upward or downward. and before a charging port 22 of the bucket 2 is positioned down, articles in it can be discharged by rotation of the bucket 2. That the bucket 2 is freely rotatable by the chains or ropes 1 on both sides means that its supported angle is constant in the case where the bucket 2 moves. For both holding the articles, and discharging the articles up or down, rotation of the bucket 2 is thus utilized.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention conveys a specific substance into a bucket at a lower portion (upper portion), conveys the conveyed material upward (downward) by the bucket, and discharges the conveyed material to the outside. The present invention also relates to a transfer and discharge device using a bucket for dumping.

[0002]

2. Description of the Related Art A bucket containing a substance is moved downward (upward).
A crane is usually used to move the product upwards (downward) and discharge the load, but such a crane is difficult to use in a narrow building.

On the other hand, the bucket initially loaded with the load is moved horizontally by a belt conveyor or the like, and then pushed into the elevator. After the elevator moves upward (downward), the bucket is removed from the elevator. A configuration in which the bucket is taken out and the carried-in matter is discharged from the bucket is also conceivable, but this requires a complicated device such as a belt conveyor and an elevator for moving the bucket, and a mechanism for taking out the bucket from the elevator at an upper (lower) position. It's inconvenient.

[0004]

SUMMARY OF THE INVENTION The present invention overcomes the above-mentioned drawbacks of the prior art and has a relatively simple mechanism, so that an article to be inserted can be inserted through the upper or side entrance. It is an object of the present invention to provide a device capable of moving a bucket loaded with the carried items upward (downward) and discharging the carried items.

[0005]

In order to solve the above-mentioned problems, the structure of the present invention has a bucket having a carry-in port for carrying a substance into one or both of an upper part and a side part, or both side ends of a supporting tool for the bucket. The parts are rotatably supported by a chain, a belt or a rope, respectively, and the chain, the belt or the rope is at a lower (upper) position for loading the article into the bucket and an upper (for discharging the loaded article from the bucket to the outside). (Below) position by the drive source,
It is designed to be capable of reciprocating movement, and in the upper (lower) position, there is provided a device for rotating the bucket or a supporting tool therefor around a portion supported by a chain, a belt or a rope. It consists of a transfer and discharge device using a bucket based on.

[0006]

1 (a) and 1 (b) show the basic structure of the present invention. As is clear from this, the bucket 2 is rotatably fixed to the chain or belt or rope 1 on both sides. Even if the chain or belt or rope 1 moves in any direction, the center of gravity of the bucket 2 is below the position supported by the chain or belt or rope 1, and the bucket 2
Is fixed in a freely rotatable state, so the bucket 1
The angle of the supported direction of is almost constant.

After the bucket 2 is moved upward (downward), the bucket 2 is rotated until the carry-in port 22 at the upper portion of the bucket 2 is located at the lower side, so that the carried-in matter inside is discharged.

That is, in the present invention, the fact that the bucket 2 is rotatably supported by the chains or belts or ropes 1 on both sides means that when the bucket 2 moves, the supported angle is substantially constant. Therefore, it is used both for maintaining the loaded state of the carried-in goods and for rotating the bucket 2 in the case of discharging the carried-in goods to the outside at the upper (lower) position.

In FIGS. 1A and 1B, the bucket 2
1 is directly rotatably supported by a chain, a belt or a rope 1. As shown in FIG. 1C, the bucket 23 is supported by the support tool 23 to support the support tool 23.
A structure in which the chain is rotatably supported by a chain, a belt, or a rope 1 also belongs to the technical scope of the present invention (however,
In the following embodiments, the bucket is directly supported by the chain, belt or rope 1. ).

A specific configuration of the present invention will be described below with reference to embodiments.

[0011]

First Embodiment Normally, the bucket 2 is moved in the horizontal direction,
Performs both vertical movement.

In FIGS. 1 (a) and 1 (b), the chain or belt or rope 1 moves horizontally in the lower (upper) position and moves to the upper (lower) position or the upper (lower) position. When it is disengaged from the position, it is moving in the vertical direction, during which the chain, belt or rope 1 is moved in a curved shape by a substantially arc.

In order to move the chain, belt or rope 1 on such a curved line, it is not possible to move it in a stable state simply by suspending them.

In order to realize such movement, a plurality of pinions for engaging the chain 1 and a plurality of pulleys for engaging the belt or the rope 1 are provided, respectively, and are arranged along a curved locus. can do.

However, providing a plurality of these pinions or pulleys is relatively complicated.

In the first embodiment, as shown in FIGS. 2 (a) and 2 (b), a curved groove is provided in the fixed portion of the apparatus, and a chain, a belt or a rope is fitted into the groove and moved. This realizes a curved movement.

[0017]

[Embodiment 2] The structure relating to the movement of the chain, belt or rope 1 of the present invention is not limited to the structure shown in FIG.

In the second embodiment, as shown in FIG. 3, the chain, belt or rope 1 is moved downward in the bucket 2 by the horizontal shift at the lower (upper) position and the vertical movement in the remaining diagonal direction. Position (upper) and upper (lower)
It realizes the reciprocating movement to and from the position.

[0019]

Third Embodiment In the present invention, as described above, the bucket 2
The device for rotating the bucket 2 is indispensable in order to discharge the carried-in matter to the outside at the upper (lower) position.

In the third embodiment, in order to realize this, as shown in FIG.
As shown in (a) and (b), the pinion 31 is provided on at least one side of the rotary shaft that projects from both sides of the bucket 2 and is rotatably fixed to the chain, belt, or rope 1.
The rack 32 is formed so as to mesh with the pinion 31 and move along the moving direction at the upper (lower) position of the bucket 2.

Inevitably, when the bucket 2 is pulled by the chain or belt or the rope 1 in the upper (lower) position and further moved while meshing with the rack 32 (the moving direction is indicated by a white arrow). Since the pinion 31 rotates with the meshing (the direction of rotation is indicated by the solid arrow), the bucket 2 sequentially changes its angle, and the carry-in port 22 initially located on the upper side gradually faces downward, so that the carry-in inside The substance will be discharged to the outside through the carry-in port 22.

Since the bucket 2 is rotatably supported by the chain, the belt or the rope 1, rather than being actually conveyed by the bucket 2, the bucket 2 often swings.

Therefore, the position where the pinion 31 and the rack 32 start meshing is unstable, and when the bucket 2 tilts at a predetermined angle based on the meshing at a predetermined target position. Not necessarily.

Therefore, in practice, as shown in FIG. 4C, the bucket 2 is pulled upward (downward) by the chain or belt or the rope 1 so that the pinion 31 moves the rack 3 into the rack 3.
2, the stopper 4 is fixed at a predetermined position below the rotary shaft 21 of the bucket 2 and on the front side in the moving direction of the bucket 2, whereby the bucket 2 engages with the stopper 4. Based on the above, it becomes possible to start the forward inclination with the movement, and the meshing between the pinion 31 and the rack 32 can be started at a fixed position.

[0025]

Fourth Embodiment In the fourth embodiment, as shown in FIG. 5, a rotary arm 33 that automatically rotates upward (downward) is provided, and when the bucket 2 arrives, the rotary arm 33 is attached to the bucket 2. Then, the bucket 2 is rotated.

The structure is more complicated than that of the second embodiment in that the drive source for the rotary arm and the control device 34 are required in addition to automatically moving the chain, belt or rope 1. As in the case of the second embodiment, it is excellent in that no special space is required for rotating the bucket 2 while moving it.

[0027]

According to the present invention having the above-described structure, the substance is carried into the bucket downward (upper) and the bucket is moved upward (upper) without the need for a space, although the structure is extremely simple. It is possible to discharge the carried-in material by moving it downward.

In the apparatus having such a structure, for example, in a decomposition process using microorganisms of organic waste, the organic waste and the culture medium in which the microorganisms that decompose the organic waste are cultured are carried into a bucket. Not only can it be applied to a device that discharges into the mixer,

The present invention can be applied to a device for loading solid matter such as livestock feed into a bucket and discharging the solid matter into a silo having an upper (lower) entrance.

As described above, the present invention has a very simple structure but can be used in various fields, and its value is immense.
