It is also possible to configure by other means including f.

(Function) Next, the present invention will be explained in detail with reference to FIGS. 1 and 2.

(2) Now, when the material to be transported is thrown into the transport material inputting phone #-tS, the material is supplied and filled into the lower part of the vertical transport device main body 1 by the feeding auger 21.

In this case, the drive motor 20 is in a driving state. Also, pull down the first aug-9 by the stroke of the lifting jack 110 rod l1m.

At this time, a large screw like a Mikkayama or Mikuchiyama is cut in the screw part 8a at the top of the auto f-driver thps, and the screw is read directly into the ratchet mechanism 22 fixed to the casing 6. The female thread part of part [3, i.e.
Since it passes through the rotation 4tlHa1 mechanism 14, when the O f-9 is pushed down by the elevating gear 11, the threaded portion 8a of the threaded drive shaft 8 is pushed down through the female threaded portion. However, the female screw portion is stopped by the ratchet mechanism 22 and remains closed. At this time, the rotation transmission part provided at the upper part is rotatable in the state shown in Figure @1, so the auger 9 rotates and enters the conveyed material filled at the lower part by the stroke of the lifting jack ■1. It is screwed in (see Figure 3 ■).

(2) Thereafter, the auger 9 is lifted upward again by the lifting jack 11, and at the same time, the auger 21 fills the place with the material to be transported (see Fig. 3 (3)).

At this time, the rotation transmission section 12 at the top lowers the drive shaft 8 of the auger 9 due to the weight of the conveyed objects on the auger 9 and ten auger blades and the resistance of the threaded portion, and as shown in FIG. The parts come together and the drive shaft stops 80 rotations.

Since the auger 9 is pushed up in this state, the female thread in the rotation control mechanism 14 attempts to rotate in the opposite direction to when the drive shaft 8 is lowered, but the ratchet mechanism 22 allows the auger to rotate freely when rotating in the opposite direction. Since the female screw portion rotates as the ff-9 is pushed up, the auger 9 does not rotate and is lifted with the object placed on the auger blade.

(2) Next, the lower end of the auger 9 is again filled with the filling material (1) in the lower part of the casing 6 (in this case, it is screwed into the filling material).

The conveyed object in the step (2) is stopped at the position raised in the above step (2) because the object filled in the lower part of the casing 6 prevents the object from descending (see FIG. 3). Then, when the object B on the lower end of the auger 9 is pulled up through the orb 9 by operating the jack 11 in step (2), it is further transported upwards.

By repeating the above operations, the objects to be transported are successively lifted upward.

In addition, the auger 21 of the conveying means i in C ridge 2\ in Fig. 3
This is a conveyed object being sent by.

Furthermore, the operation of the present invention will be explained in detail. Even if you use a conventional screw core bearer as it is and rotate the Orboo in a vertical or nearly vertical state to convey soil, powder, etc. to the top, the objects on the Orboo blades will be placed in a concentric horizontal plane as described above. It is possible to move the position, but upward movement is not possible. Unlike when using a screw conveyor at an appropriate angle, the capacity decreases to nearly zero. Therefore, in order to use the screw conveyor vertically, an external force must be applied to the lowest part of the screw conveyor. In this case, the lifting distance of the transported object varies depending on its properties, specific gravity, etc., but transport is not impossible. This is only an external force and is not a function of the screw conveyor itself, so when the external force disappears, the conveying force also disappears. In particular, materials with high specific gravity and rough surfaces on the particle sides, such as earth and sand, undergo rapid consolidation due to their own weight that acts vertically downwards, and due to imaging accompanying the rotation of the auger, etc. Friction increases, and transportation becomes extremely difficult, and the ascent stops after a short period of time.

In this case, increasing the external force from below will only increase consolidation and friction, and the effect will be extremely small, and the auger will spin idly due to damage to the equipment or strong adhesion of dirt and sand to the auger, and the dirt will continue to rise. stomach.

Of course, objects with low specific gravity or particles with smooth surfaces require a slightly longer upward conveyance distance than dirt, etc., but as long as a screw conveyor is used for vertical conveyance, the same phenomenon as in the case of dirt, etc. will always occur. It is something.

On the other hand, in the present invention, the lower end of the auger 9 is screwed into the conveyed object taken under the auger 9, and the conveyed object is placed on the auger blades, and the upward movement of the conveyed object is caused by the rotation of the auger 9. This is achieved by raising the auger 9 via the jack 11 instead of relying on the However, in this case, when the jack 11 etc. is lowered and the auger 9 is moved downward again, the object also falls and cannot be transported to the upper part. However, in the present invention, the object is moved to the lowest part of the casing 9 at the same time as the upward movement of the auger 9 is started. Since the objects to be transported are forcibly fed and filled by an external force (second conveying means i), the descending of the objects and persons who were initially pulled upwards is prevented by the filling of the objects to be transported and kept at the upper position. Prevent descent. By repeating this movement, vertical conveyance is performed.

That is, the present invention does not particularly expect the movement of the proboscis due to the rotational force of the auger of the conventional screw conveyor, but utilizes the supporting force of the auger blades and the filling of the conveyed material in the lower part of the conveyor.

For this reason, since the space between the auger blades (pinch) can be said to be a kind of kerato, the auger blades in the vertical state can be seen as packets arranged continuously. However, the major difference from a normal 9-keit transport device is that there are no empty packets (returns). With this continuous f-Kent method, when earth and sand are conveyed vertically using a screw conveyor, the most harmful compaction is dispersed by the supporting force of the auger blades and does not become large, so the friction with the casing that occurs due to compaction is naturally small. The effect on the vertical movement of the auger is also small.

Note that the rotation of the auger 9 is effective in reducing friction, and is also advantageous in reducing resistance when the lower end of the auger is inserted into the conveyed material filled in the lower part by the downward movement of the device.

That is, in the present invention, unlike the conventional screw core pair, the rotational force of the auger is not used as the main conveying force, but because the auger plays the role described above, the rotational force can be made extremely small.

FIG. 4 shows a second embodiment of the present invention, and this second embodiment also has a first conveying means flame and an auger 9 of this first conveying means A, substantially similar to the above-mentioned embodiment. At the lower end of the vertically reciprocating means l and the rotating means 1', and the first conveying means λ, there are provided a second conveying means i for supplying and filling the contents with conveyed material.

Thus 2 in this case the 11th second conveying means λ.

i and the means 1° for reciprocating the auger 9 are constructed substantially the same as in the first embodiment.

On the other hand, the means 1' for rotating the auger 9 is constituted by a drive motor 5 and a rotation transmitting section 26 comprising a gear mechanism or the like. That is, the drive motor 25 is provided on the drive transmission gear storage case n, and a drive transmission gear is provided on the motor shaft 25m extending into the case 27, and this drive transmission gear 28 is provided on the electric motor 41]8 side. The drive transmission ear 29 meshes with the drive transmission ear 29. In this case, it goes without saying that the drive motor 25 may be provided below the case n. A gear 30 is provided in the center of the drive transmission gear 29 and meshes with a threaded portion 8 formed on the upper part of the drive shaft 8, and the rotational force of the drive motor 25 is transmitted to the drive shaft through these gear mechanisms. 8. Note that 31 is a bearing 32 supporting the motor shaft 25m, and 33 is a bearing disposed above and below a gear 30 disposed within the case 27.

Moreover, 34 is an auger shaft support member, which is a member that allows the drive shaft 8 to move up and down while rotating.

That is, the auger drive shaft 8 is always rotated in the same direction by the drive motor 25 while the auger shaft support 3
4 and is moved up and down by a lifting jack 11.

Further, 36 is a support member that supports the case 27, and is provided at the upper part of the casing 6 so as to face each other upward, and the case 27 has a built-in gear mechanism at its upper end.
is placed. Incidentally, a lifting jack 11 constituting a means 1 for reciprocating the auger 9 is fixed to the upper part of the casing 6, and the tip of the 70 rod tta is connected to the auger shaft support member A.

(for production) Next, the operation of this embodiment will be explained.

First, by operating the lifting jack 11, the auger 9 is pushed up by the jack stroke via the auger sleeve support member 34, which slides up and down while rotating the drive shaft 8. At this time, the transported material is supplied and filled into the part for taking in the transported material formed below the casing 6 via the second conveying means i' consisting of an auger or po/g for filling the transported material, and the auger is filled with the transported material. 9 is rotated and lowered so as to penetrate into the loaded conveyance.

The auger 9, which has descended by the stroke of the lifting jack 11, is pushed up while rotating in the same direction with the conveyed object placed on the auger blades.

At this time, the second conveyance means i simultaneously supplies and
Fill.

The above-mentioned operation corresponds to the state shown in FIG. 3. Next, the auger 9 moves downward while rotating in the same direction, but the transported objects such as dirt and powder on the auger blades remain in the same position and are newly taken in and filled. It is screwed into conveyed object B.

At this time, the second conveying means 5' with the filling gap acts as a retainer, and the conveyed object B is not pushed back, resulting in the state shown in FIG. 3 (2).

Therefore, the deposit box initially located at the lower end will be sequentially transported upward.

As described above, the conveyed object is gradually conveyed upward as the auger 9 repeats reciprocating motion up and down.

(Effects of the Invention) As described above, according to the present invention, there is a casing installed vertically, an auger provided inside the casing, and capable of reciprocating up and down via a lifting jack. , means for rotating the auger at least during its downward movement;
The lower end of the casing is provided with means for supplying and filling the conveyed material at the same time as the auger is moved upward, and the auger is rotated and moved downward so that the lower end of the auger is supplied to the conveyed material supplied to the lower end of the casing. Then, the auger is pulled up and moved upward to pull up the conveyed object, and at that time, the conveyed object is occasionally supplied and filled into the lower part of the casing, and the auger is moved downward again to pawn the conveyed object. By repeating the same process, the objects can be continuously and easily transported upwards. It does not require a large amount of force, and it produces almost no noise, making it much safer.

In addition, since the device is very single, it is easy to operate and has fewer failures. Furthermore, compared to the conventional methods (packet method, crane method, etc. mentioned above), the equipment is smaller and the installation area is extremely small, so the cost is naturally low, and if the above advantages are taken into consideration, it can be used for a wide variety of purposes. It's something you get.
