Abstract

PROBLEM TO BE SOLVED: To certainly and highly efficiently crush even lightweight refuse such as planer refuse by arranging at least two rotary drums side by side in a state of traversing the interior of an apparatus main body and rotationally driving at least one rotary drum. SOLUTION: Two rotary drums 6 are arranged side by side in a state traversing the interior of an apparatus main body 5 and one rotary drum 6 is rotationally driven by a belt transmission means and a motor. Sending teeth 10 are provided to this rotary drum 6 in a protruding state and cooperation teeth 12 are provided to the sending teeth 10. When one rotary drum 6 is rotated by meshing the cooperation teeth 12 with each other, the other rotary drum is also rotated synchronously in a relatively reverse direction. Therefore, an involving region E of lightweight refuse is formed on the upper side of both rotary drums 6. The arranging distance between the rotary drums 6 is determined so that a predetermined gap S is held between both of them even if the sending teeth 10 are opposed to each other. This gap S prevents the clogging with lightweight refuse between the sending teeth 10.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light-weight waste pumping device that can be used for finely crushing light-weight waste such as wood chips, and a crushing treatment apparatus equipped with this pressure-feeding device.

[0002]

2. Description of the Related Art Since wood chips having a fine grain size such as sawdust can be reused in livestock production, agriculture, etc., the applicant of the present invention is able to process relatively large wood chips such as cut wood and long wood with high efficiency. A chip making machine which can be crushed into a scrap waste state has been proposed (see Japanese Patent Publication No. 61-16603). This chip making machine is provided with a rotary cylinder that is rotatable about a horizontal axis near the bottom of the tank into which the end cutting material is put,
The rotating cylinder is provided with a crushing blade, and a receiving blade is provided on the outer peripheral portion of the rotation locus. The long material can be inserted into the lower peripheral surface of the rotary drum through the side wall of the tank.

[0003]

By the way, even with the same wood chips, the planer chips discharged from the planer are not only thin and lightweight, but also because each one is curled,
It has the feature of being bulky despite its low aggregate density. For this reason, even if only the planer scraps were thrown into the chip making machine, there was a phenomenon in which the scraps were soared by the wind pressure of the rotating drum, and the chips could not be ground properly. In addition, if you mix the planer scraps with an appropriate amount of scrap material,
Although it was possible to grind to some extent, it is not always the case that the planer scraps and the end cuttings are generated at the same time, and the mixing thereof is troublesome. It had been disposed of. Therefore, it was wasted in terms of resources and disposal costs.

The present invention has been made in view of the above circumstances, and is capable of reliably and efficiently crushing even small-sized scraps such as planer scraps, and wastes resources and disposal costs. It is an object of the present invention to provide a lightweight waste pumping device capable of omitting the above, and a crushing treatment device including the pumping device.

[0005]

According to the present invention, the following technical measures have been taken in order to achieve the above object. That is, according to the first aspect of the present invention, the apparatus main body having a passage space in the vertical direction, at least two rotary drums arranged in parallel with each other across the inside of the apparatus main body, and the upper side of the rotary drums with respect to each other. It is characterized in that it has a drive means for transmitting the rotational drive force to at least one of the rotary drums so that the winding action is generated in the interspace portion.

[0006] With such a structure, when the lightweight scraps are thrown in from the upper part of the apparatus main body, the lightweight scraps are sequentially caught between the rotating drums and are sent downward with a strong pushing force. Become. Therefore, for example, if the above-described chip manufacturing apparatus is provided in the lower part of this pumping device, it is possible to reliably supply light scraps such as planar scraps to the chip manufacturing apparatus with a strong pushing force, and crushing of the lightweight scraps. It can be done with high efficiency.

It is preferable to maintain a gap between the rotating drums that is not blocked by rotation (claim 2). By doing so, it is possible to prevent clogging of lightweight scraps between the rotating drums as much as possible. The gap between the rotating drums is
It refers to the situation where lightweight scrap is not thrown in.

A plurality of feed dogs may be provided on the outer peripheral surface of the rotary drum at predetermined intervals in the circumferential direction (claim 3). By doing so, the winding force and the pushing force of the lightweight scraps can be strongly generated, which is even better. When the feed dog is provided on the rotary drum as described above, the rotary drum can be interlocked by partially engaging the feed teeth with each other (claim 4).

[0009] With this configuration, by simply rotating one of the rotating drums, the other rotating drums are driven to rotate and synchronism can be obtained. Therefore, a transmission structure provided as a driving means is unnecessary. There is an advantage that it can be realized. A partition plate may be provided inside the apparatus main body so as to vertically partition a portion other than the effective winding area formed by the rotary drums (claim 5).

By doing so, it is possible to prevent unnecessary blowing up of air in the main body of the apparatus, so that there is an advantage that the flying up of the lightweight scraps can be made as small as possible. The rotary drum itself can be configured to exert an action of blocking an air flow that blows up in the main body of the apparatus (claim 6). That is, since the passage space in the main body of the apparatus is substantially filled with the rotating drum itself, and the rising air flow is less likely to occur,
It is possible to prevent light dust from flying up and being difficult to be caught in the rotary drum.

A crushing device for crushing a lightweight shavings according to any one of claims 1 to 6 by receiving at least one crushing blade that receives the lightweight shavings sent downward between the rotating drums. By providing (a component equivalent to the main part of the conventional chip manufacturing apparatus), a crushing apparatus for lightweight scraps can be configured (claim 7). Needless to say, this enables integration as a crushing treatment device.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 5 show the first embodiment of the present invention.
The pumping device 1 of the embodiment is shown, and this pumping device 1
As shown in FIG. 2 and FIG. 3, is combined with the crushing device 2 and its installation base 3 to form a crushing treatment device 4 for light weight waste.

The pressure feeding device 1 has a device main body 5 having a passage space directed in the vertical direction, two rotary drums 6 arranged side by side across the inside of the device main body 5, and one rotary drum 6 is rotationally driven. And drive means 7 for transmitting. The drive means 7 has a belt transmission means 8 and a motor 9. As shown in FIGS. 1 and 4, the rotary drum 6 is formed by projecting the axially long feed dogs 10 at predetermined intervals in the circumferential direction on the outer peripheral surface of a cylindrical body that is long in the axial direction. ,
The rotation axes of the adjacent rotary drums 6 are parallel to each other.

The feed dog 10 is provided with interlocking teeth 12 projecting from both ends in the axial direction more than other parts. The interlocking teeth 12 are engaged with each other between the two rotary drums 6. Therefore, as described above, by simply rotating the one rotating drum 6 by the driving means 7, the other rotating drum 6 can be rotated synchronously and in the opposite direction. Therefore, in the upper part of the both rotary drums 6, the winding area E where the lightweight scraps thrown into this part are taken in and pushed out downward.
Can be formed. This entrainment area E has an effective area between the rotational axes of the rotary drums 6.

Incidentally, due to the meshing relationship between the interlocking teeth 12,
The feed dogs 10 in each rotary drum 6 have a positional relationship that is displaced from each other alternately. Even if these feed dogs 10 are opposed to each other, the feed dogs 10 are located between them (between the loci drawn by the tips of the feed dogs 10). Is arranged so that the predetermined distance S is maintained so that the parallel installation distance of the rotary drums 6 is determined. This gap S is
The purpose is to prevent light dust from clogging between the feed dogs 10. As the gap S, the cross-sectional shape of the feed dog 10 and the protruding pitch, the diameter of the rotary drum 6 and the rotation speed,
Although there are some changes depending on the size of the lightweight scraps,
As an example, when the diameter of the rotary drum 6 including the feed dog 10 is 300 mm or more and the number of rotations is around 500 rpm, the gap S is preferably about 30 to 40 mm.

Inside the apparatus main body 5, each rotary drum 6 fills most of the passage space. Therefore, the air flow (refer to arrow X: this air flow is generated by the lower crushing device 2) attempting to blow up in the device body 5 is blocked by the rotating drum 6 itself, and the rotating drum 6 itself is blocked. It is prevented that the lightweight debris on the upper part rises up and becomes difficult to be caught.

A partition plate 1 is provided inside the apparatus main body 5 so as to project downwardly toward the upper side of each rotary drum 6.
5 are provided. It goes without saying that the partition plate 15 has the function of guiding the lightweight scraps to the winding area E.
It also has a function of vertically partitioning the portion excluding the entrainment area E. That is, the airflow that is about to be blown up along the inner wall surface of the apparatus main body 5, the rotational wind pressure of the rotary drum 6 and the like (see the arrow Y) will be repelled downward by the partition plate 15, and also the rotary drum. Feed dog 1 at 6
In the region in which 0 rotates upward, the light debris does not come into contact with it, so that the light debris does not fly up and is agitated.

As shown in FIGS. 2 and 3, this device body 5
An inspection lid 18 is provided on the lower part of the crushing device 2 for maintenance of the crushing device 2. On the other hand, the crushing device 2 is a box-shaped device body 2
In FIG. 0, there is provided a rotary drum 21 which is rotatable about a horizontal axis, and the rotary drum 21 is rotationally driven by a drive means 25 having a belt transmission means 23 and a motor 24. . The rotary shaft of the rotary drum 21 is orthogonal to the rotary shaft of the rotary drum 6 in the pressure feeding device 1.

As shown in FIG. 5, crushing blades 27 are attached at two opposite positions on the outer peripheral surface of the rotary drum 21, and receiving blades 28 are inserted at the peripheral portion of the rotation range. The crushing blade 27 and the receiving blade 28 are used to crush lightly debris into fine pieces. Further, a sorting body 32 curved along the rotation locus of the crushing blade 27 is provided at the lower part of the rotary drum 21 so that lighter waste less than a predetermined grain size does not pass through and promotes further crushing. There is.

Inside the apparatus main body 20, a guide plate 33 is formed so as to project downwardly toward the upper side of the rotary drum 21.
Is provided so that the rotation of the rotary drum 21 does not agitate the lightweight waste. In the crushing processing device 4, when the crushing blade 27 or the receiving blade 28 of the crushing device 2 is spilled or worn, the device body 5 of the pressure feeding device 1
Open the inspection lid 18 provided on the crushing blade 27 and the receiving blade 28
Since the guide plate 33 is attached and detached or adjusted, the guide plate 33 can be easily removed from the upper portion of the rotary drum 21 as necessary, although not shown (for example, attachment and detachment by a screwing structure or a hinge connection structure). ).

In the crushing apparatus 4 having such a structure, when lightweight waste such as planar waste is introduced from the upper part of the apparatus main body 5 of the pressure feeding apparatus 1 by a cyclone device or a conveyor device (all are not shown), it becomes lightweight. The waste is rotated by the rotating drum 6 and dropped into the device body 20 of the crushing device 2, and is supplied. When the inside of the crushing device 2 is filled with the lightweight waste, the rotating drum 6 pushes the waste downward, so that the rotating drum 2
The compression of the lightweight waste toward 1 is performed. Therefore, the lightweight waste is reliably crushed between the crushing blade 27 and the receiving blade 28, and is dropped and discharged to the lower part of the crushing device 2 via the sorting body 32.

When it is not necessary to use the pressure-feeding device 1 in the crushing treatment device 4 when, for example, crushing an end material, the inspection lid 18 of the device main body 5 in the pressure-feeding device 1 is opened, From this point, it is possible to use it so as to insert the end cutting material. In this case, from the viewpoint of protecting the pressure feeding device 1 from the splashing of the end cutting material by the crushing device 2, the device main body 5 has a large height dimension from the holding position of the rotary drum 6 to the installation position of the inspection lid 18. It is preferable to leave it. Further, it is preferable that a supply duct (not shown) for the end cutting material is connected to the apparatus main body 5 without a gap in a state where the inspection lid 18 is opened so as to prevent scattering of crushed debris.

6 to 8 show a modified example of the crushing processing apparatus 4. In this crushing processing apparatus 4, the pressure feeding device 1 and the crushing device 2 are integrally formed. The pumping device 1 is the second embodiment of the present invention, and the crushing device 2 is also slightly different in configuration from the above. The pressure feeding device 1 of the second embodiment is the above first
The most different point from the embodiment is that, as shown in FIG. 7, two rotary drums 6 are related to each other so that the feed dogs 10 face each other.
2 is not provided. Therefore, as shown in FIG. 6, the rotary shafts of the respective rotary drums 6 are connected via the interlocking gear 40 so that they can perform synchronous and relative reverse rotation. Although not shown, the driving means 7 is adapted to transmit rotational power to one of the rotary drums 6 or the interlocking gear 40.

The other detailed structure and operation are substantially the same as those of the first embodiment, and therefore those having the same operation will be denoted by the same reference numerals and detailed description thereof will be omitted. Crushing device 2
Are two rotary cylinders 21 parallel to each other as shown in FIG.
have. These rotary drums 21 are provided so that the rotary drum 6 of the pressure feeding device 1 and the rotary shaft are parallel to each other.
Then, these rotary drums 21 are rotationally driven by different driving means 25 (see FIG. 6). Each of the rotary drums 21 is rotated so as to face outward, and a separation guide 43 having a triangular cross section is provided between the rotary drums 21. That is, the rotary drums 21 mutually perform crushing action independently.

The blade 28, which is inserted toward the rotary drum 21 shown on the left side of FIG. 8, is horizontally provided at a position close to the lower surface of the rotary drum 21. An insertion port portion 45 of an unnecessary long material (not shown) is provided corresponding to the receiving blade 28. Reference numeral 46 is a guide table, and 47 is the apparatus main body 20.
Is a lid swingably provided on the side wall of the. By providing such a structure, not only lightweight scraps and end cuttings but also long materials can be crushed.

By the way, the present invention can be modified in various ways other than the above embodiments. For example, in the pressure feeding device 1, three or more rotary drums 6 can be provided. Needless to say, the number of protrusions of the feed dog 10 in the rotary drum 6 can be appropriately changed, but the feed dog 10 may not be provided. For example, the cross-sectional shape of the rotary drum 6 can be a radial shape including a polygonal shape or a cross shape, or can be circular and the peripheral surface can be roughened.

The drive means 7 for the rotary drum 6 may be provided for each rotary drum 6, or in combination with the crushing device 2, the drive means 25 for this may also be used. It goes without saying that the pressure feeding device 1 can be distributed as a product by itself (without being combined with the crushing device 2).

[0028]

As is apparent from the above description, in the present invention according to claim 1 (light weight waste pumping device), there is provided a device main body having a passage space in the vertical direction and a state of traversing the inside of the device main body. At least two rotating drums arranged side by side,
Since it has a driving means for transmitting the rotational driving force to at least one of the rotating drums so that the rolling action is generated between the upper parts of the two rotating drums, in the case where lightweight scraps are thrown in from the upper part of the apparatus main body. The light dust is sequentially rolled up between the rotating drums and is sent downward with a strong pushing force. Therefore, for example, if the above-described chip manufacturing apparatus is provided in the lower part of the pressure feeding device, it is possible to reliably supply light scraps such as planar scraps to the chip manufacturing apparatus with a strong pushing force, and crushing of the lightweight scraps is possible. It can be done with high efficiency. Therefore, the crushed scraps thus obtained can be reused in livestock production, agriculture, etc., and waste of resources and disposal costs can be eliminated.

If a gap that is not blocked by rotation is maintained between the rotating drums (claim 2),
It is possible to prevent light dust from clogging between the rotating drums as much as possible, and it is possible to improve the operating efficiency of the device.
Providing a plurality of feed teeth on the outer peripheral surface of the rotary drum at predetermined intervals in the circumferential direction (Claim 3) makes it possible to more strongly generate the winding force and the pushing force of the lightweight scraps, which is preferable. Is. Further, when the feed dogs are provided in this way, if the rotary drums can be interlocked by partially meshing the feed teeth with each other (claim 4), only one of the rotary drums can be rotationally driven. Since all the rotating drums can be synchronously and relatively reversely rotated, there is an advantage that a transmission structure provided as a driving means can be eliminated.

If a partition plate is provided in the inside of the main body of the apparatus for partitioning the portion except the effective entrainment area formed by the rotary drums in the vertical direction (claim 5), it is useless within the main body of the apparatus It has the advantage that it can prevent the wind from blowing up, and can reduce the fly-up of lightweight scraps as much as possible. Therefore, it is possible to ensure the inclusion of the lightweight waste. If the rotating drum itself is configured to have an effect of blocking the air flow that blows up in the main body of the device (Claim 6), the air flow that blows up can be blocked, so that it is also possible to prevent light dust from flying up. This leads to the advantage of being able to ensure the inclusion of waste.

Further, according to the present invention of claim 7 (the apparatus for crushing light-weight waste), the light-weight waste sent downward from the pressure feeding device is crushed by the crushing device, and the device can be integrated. Has become.
