Description

Aggregates screen moduler with bending support structure}

The present invention is an aggregate sorting screen modular, and more specifically, because it can be installed in an appropriately bent state in the field installation where aggregate sorting is required, an aggregate having a new configuration bending support structure that can increase convenience during installation It relates to a screen screen modular.

In general, a large amount of rubble is generated in the process of blasting masonry for road construction or tunnel construction, or blasting masonry for stone extraction in a quarry, and these rubble is used to form a subbase of the road surface, etc. There are many cases. For example, rubble is often used in the construction and construction fields, such as asphalt paving or basic construction of buildings. Even if rubble is used for the formation of an auxiliary base on the road surface or basic construction of buildings, the amount of rubble remaining remains considerable. Therefore, recently, crushed rubble is shredded by a crusher, and the crushed rubble is sorted into aggregates having different sizes for each particle by a separate aggregate sorting device and recycled.

In the aggregate sorting device, a screen for screening through which the aggregate passes is required to sort the aggregate by size. The screen for aggregate sorting provided in the aggregate sorting device is installed at an angle inclined to the aggregate input end, and the aggregate is input and passed over the screen for sorting, and vibration (vibration) is applied to the screen for sorting to sort the aggregate. That is, the screen for sorting is operated to vibrate, and the aggregate is introduced and passed over the screen for screening, so that aggregates of a predetermined particle size fall through a plurality of sorting holes formed on the screen for screening, so that the aggregate can be sorted. .

On the other hand, the screen for screening for sorting aggregate is installed obliquely at the input site of the aggregate, and by applying vibration to the screen for screening arranged inclined like this, the aggregate is supplied to the screen for screening from the input end to follow the screen for tilting screening. As it flows down, it adopts many methods of sorting aggregates in such a way that aggregates fall out through a plurality of sorting holes formed on the screen for sorting.

The aggregate sorting screen modular is made of rubber and has a reinforced frame inside. At this time, the aggregate screening module made of rubber material is configured to be provided with a connecting groove in the form of a female groove and a connecting piece in the form of a male stone on both side ends, and a rubber-based aggregate screening screen module with a built-in reinforcement frame is provided at the aggregate input point. It is installed obliquely, but a plurality of aggregate screening screen modules are subsequently installed in the vertical direction. When a plurality of aggregate sorting screen modules are installed by connecting them in an up-down, left-right direction, each of the individual aggregate sorting screen modules installed adjacent to each other in the left-right direction is connected grooves at one side end and a connecting support piece is an adjacent aggregate sorting screen module It fits into the connection support piece and the connection groove of the. If the three adjacent aggregate screening modules are installed by connecting them in the left and right directions, the connecting grooves provided on one side end of the center aggregate screening module are coupled to the connection support pieces of the aggregate screening modules adjacent to one side. , The connecting support piece of the aggregate sorting screen module in the middle goes under the connecting support piece of the aggregate sorting screen module adjacent to one side and enters into the connecting groove of the aggregate sorting screen module adjacent to one side and is connected, while the other The connecting support piece provided at the side end portion enters into the connecting groove of the aggregate screening module adjacent to the other side, and the connecting support piece of the aggregate screening module adjacent to the other side is connected to the other side end portion of the aggregate screening screen module in the middle. It enters under the connecting support piece at and enters into the connecting groove at the other end of the aggregate screening screen modular in the middle. Where aggregate sorting is required in this way, a plurality of aggregate sorting screen modulars are installed connected in the vertical direction and the horizontal direction.

At this time, in order to install by connecting in the vertical, horizontal direction, as described above, each individual aggregate sorting screen modulator should be properly bent in the area between the left and right side ends to connect the grooves and connection support pieces of each aggregate sorting screen module. It is possible to easily connect and install a plurality of aggregate sorting screen modules in a fitting manner.

By the way, the aggregate screen screen modular of rubber material having a reinforcement frame of a metal material therein is not able to properly bend the area between the left and right side ends due to the reinforcement frame of the metal material inside, so it is difficult to connect the aggregate screening screen modules There is an easy problem. Individual aggregate screening screen modules must be properly bent upwards or downwards in the area between the connection grooves and both side ends of the connection support pieces, in such a way that the connection grooves and connection support pieces of adjacent aggregate screening screen modules are sandwiched. Although it can be easily connected, the area between both ends of the individual aggregate screening screen modules cannot be bent due to the reinforcement frame of the metal material that enters the interior of the aggregate screening screen module. There is a difficulty in connecting the support pieces in a manner that fits.

In other words, the connection groove 22 is disposed above the one side end portion of the modular body 20 in a state where the upper end or the lower end of the modular body 20 is placed in front, and the connection support piece 24 is disposed below. In the case, the connecting support piece 24 is disposed above the other side end of the modular body and the connecting groove 22 is disposed below.

The side reinforcement bar 32 is made of a metal bar. The side reinforcing bar 32 is made of, for example, a bar of a cross-section square metal material.

The bending rigid bar 234 is disposed in a direction crossing both side ends of the modular body 20 and is embedded in the modular body 20. Both ends of the bending rigid bar 234 are connected to the side reinforcement bar 32. The bending rigid bar 234 is composed of a rigid bar capable of bending an area between both ends connected to the side reinforcement bar 32. The bending stiffness bar 234 is a bending bar when a force to bend acts, and after bending, means a bar having stiffness that is maintained in a bent state. The bending rigid bar 234 is, for example, a bending bar when a force to bend is applied, such as a neck bar connecting the main body and the lighting part in the stand lighting lamp, and after bending, is a rigid bar that remains in the bent state.

In the present invention, two side reinforcement bars 32 are arranged side by side, and both ends of the two bending rigid bars 234 are connected to the two side reinforcement bars 32, thereby bending the side reinforcement bars 32. The rigid bars 234 are configured in a square frame shape. Two side reinforcement bars 32 and two bending rigid bars 234 forming a square frame shape are embedded in the modular body 20 made of rubber. At least two side reinforcement bars 32 are embedded in the modular body 20 in a state where at least two side reinforcement bars 32 are arranged in a direction parallel to both side ends of the modular body 20 and 10. .

When a force to bend upward or downward acts on an area between both side ends of the modular body 20 in a state in which the upper end or the lower end of the modular body 20 is viewed from the front, the bending rigid bar 234 is moved upward or downward. As bending, the area between both side ends of the modular body 20 can be bent upward or downward together with the bending rigid bar 234. When the side between both side ends of the modular body 20 is called the width direction and the length between the upper and lower parts of the modular body 20 is called the longitudinal direction, the width direction of the modular body 20 can be bent in the vertical direction.

The aggregate screening screen modular according to the present invention having the above-described configuration is installed by connecting in the vertical direction. The connecting groove 22 and the connecting support piece 24 of one side end of each individual aggregate sorting screen modular arranged adjacent to each other in the left and right directions are connected to the connecting support piece 24 and connecting groove of the adjacent aggregate sorting screen modular ( 22). If three adjacent aggregate sorting screen modules are connected and installed in the left and right directions, the connection groove 22 provided at one end of the center aggregate sorting screen module supports connection of the aggregate sorting screen module adjacent to one side. The piece 24 is coupled, and the connecting support piece 24 of the middle aggregate screening screen modular enters under the connecting support piece 24 of the aggregate sorting screen modular adjacent to one side and connects the groove of the aggregate sorting screen module adjacent to one side ( 22) On the other hand, the connection support piece 24 provided on the other side end of the center aggregate screening screen module in the middle enters and joins the connection groove 22 of the aggregate screening screen module adjacent to the other side, and is coupled to the other side. The connecting support piece 24 of the adjacent aggregate sorting screen modular enters below the connecting support piece 24 on the other side end of the center aggregate sorting screen modular and is located at the other side end of the middle aggregate sorting screen modular. It enters the connecting groove 22 and is coupled. Where aggregate sorting is required in this way, a plurality of aggregate sorting screen modulars are installed connected in the vertical direction and the horizontal direction.

At this time, in the present invention, the modular body 20 has a bending rigid bar 234 built in the direction intersecting both the left and right side ends of the connecting groove 22 and the connecting support piece 24 in the modular body 20. When the force to bend the area between the left and right side ends of the 20) upwards or downwards, the modular body 20 is made of a rubber material and can be bent by itself, and the bending rigid bar 234 is modular The bending rigid bar 234 is also bent upward or downward when the force to bend the modular body 20 upward or downward in the area between both side ends is disposed in the width direction of the body 20, and thus the modular body ( Since the area between the left and right side end portions of 20) can be bent upward or downward, the modular body 20 adjacent to the connection groove 22 and the connection support piece 24 of one side end portion of the modular body 20 The connecting support piece 24 and the connecting groove 22 of the other side end portion of the modular body 20 are connected to the connecting support piece 24 and the connecting groove 22 of the modular body 20, and the adjacent neighboring modular body ( 20) is inserted into the connecting groove 22 and the connecting support piece 24 to be coupled.

On the other hand, the aggregate sorting screen modular has a connecting groove (22) (22) and a connecting support piece (24) (24) provided on both side ends of the modular body (20, 20) of the modular body (20) (20) When viewed from the upper end or the lower end, it is disposed on the same line sideways, the connecting grooves 22 and 22 are disposed on the upper side, and the connecting support pieces 24 and 24 are the A-type screen modular disposed on the lower side and the connecting supporting piece ( 24) (24) is disposed on the upper side, and there is a B-type screen modular in which the connecting grooves (22) and (22) are disposed on the lower side. Can.

The bending rigid bar 234 and the modular body 20 embedded in the modular body 20 or 20 of the A-type screen modular or B-type screen modular when the A-type screen modular and the B-type screen modular are installed side by side. ) In the state in which the 20 is bent together, it is possible to fit and fit the connecting coupling pieces and the connecting grooves 22 and 22 of the neighboring A-type screen module and the B-type screen module.

Therefore, the aggregate selection modular of the present invention can be easily connected to the connecting groove 22 and the connecting support piece 24 to the adjacent modular body 20 by bending the modular body 20 appropriately when trying to install in a plurality. Since it can be connected, it is very convenient for on-site installation, but also reduces the time during installation. When a plurality of aggregate sorting screen modules are to be installed by connecting them in the vertical direction, the area between the left and right side ends of the modular body 20 in each individual aggregate sorting screen modular should be properly bent to make each aggregate sorting screen modular It is possible to easily connect and install a plurality of aggregate sorting screen modules by fitting the connection grooves 22 and the connection support pieces 24 of the present invention. As the present invention can properly bend the modular body 20 part as described above, , It is possible to easily connect and install a plurality of aggregate screening modules. Bending of a rigid metal bar structure capable of returning to the original state together with the modular body 20 made of rubber when the bending force is released while bending is possible while the main part is a rubber body made of a modular body 20 Since the rigid bar 234 is built-in, the area between both ends of the aggregate sorting screen modules, that is, the area between both ends of the modular body 20 is properly bent to the extent necessary, so that the aggregate sorting screens adjacent to each other are screened. It is to solve the difficulty in connecting the connection grooves 22 and the connection support pieces 24 of the modular type.

In addition, the modular body 20, which is the main part of the present invention, is made of a rubber material, and thus has a lighter weight, so it is more convenient when installing on site. Since the relatively light screen modulator of the present invention is installed in the field, the convenience felt by workers in the field is very high.

Meanwhile, the present invention may be configured such that at least two side-by-side support bars 334 are connected to two side-by-side bars.

The support bar 334 is composed of a strip-shaped metal bar. The support bar 334 is disposed in a direction intersecting both side ends of the modular body 20 and is embedded in the modular body 20. It is embedded in the modular body 20 in a state where a support bar 334 is disposed between the bending rigid bar 234 and the top or bottom surface of the modular body 20. Both ends of the support bar 334 are connected to the side reinforcement bar 32. The support bar 334 is composed of a rigid bar that is bendable between the two ends connected to the side reinforcement bar 32.

In the embodiment of the present invention, two side reinforcement bars 32 are arranged side by side, and both ends of the two support bars 334 are connected to the two side reinforcement bars 32, so that the side reinforcement bars 32 are provided. And support bars 334 are configured in a square frame shape. Two side reinforcement bars 32 and two support bars 334 forming a square frame shape are embedded in the modular body 20 made of rubber. At least two side reinforcement bars 32 are embedded in the modular body 20 in a state where at least two side reinforcement bars 32 are arranged in a direction parallel to both side ends of the modular body 20 and 10. .

The side reinforcement bars 32 are disposed in a direction parallel to both left and right side ends of the modular body 20 and are embedded in the modular body 20. The side reinforcement bars 32 are arranged in a direction parallel to the connection grooves 22 and the connection support pieces 24 provided at both left and right side ends of the modular body 20.

The upper end and the lower end of the support bar 334 are connected to the side reinforcement bars 32 at both ends of the support bar 334 in a state arranged in parallel with the upper and lower parts of the modular body 20. The support bar 334 is disposed in a direction parallel to the upper and lower parts of the modular body 20. At least two support bars 334 are disposed in a direction orthogonal to the side reinforcement bars 32. At this time, both sides of the support bar 334 are arranged in a direction parallel to the top and bottom surfaces of the modular body 20, and the width between the upper and lower ends of the support bar 334 is between the both sides of the support bar 334. It is composed of a larger strip-shaped metal plate than the width of. Therefore, the region between both ends of the support bar 334 connected to the side reinforcement bar 32 is composed of a bendable rigid bar. The support bar 334 is configured in a cross-section rectangular bar shape. When the support bar 334 is embedded in the modular body 20 and the modular body 20 is viewed as a side cross-section or an up-down cross-section, the support bar 334 is configured as a cross-sectional right-angle bar shape.

On the other hand, that the support bar 334 is a rigid band-shaped metal plate structure has a stiffness that allows the support bar 334 to be unfolded in its original state by bending between both ends of the support bar 334 and releasing the bending force. It means that it is a strip-shaped metal plate. The width between the upper and lower surfaces of the modular body 20 in the support bar 334 (ie, the upper and lower surfaces) is between the upper and lower parts of the modular body 20 and the upper and lower parts of the modular body 20 in the support bar 334. The area between both ends of the support bar 334 can be bent at the same time when the force between the side ends of the modular body 20 is bent (the force to bend) when it is thinner than the width of the modular body 20. The area between both side ends of the body 20 may also be bent together with the support bar 334. When a force to bend upward or downward acts on an area between both side ends of the modular body 20 in a state where the upper end or the lower end of the modular body 20 is viewed from the front, the support bar 334 moves upward or downward. While bending, the modular body 20 can also be bent upward or downward along the support bar 334 with the area between both side ends. When the side between both side ends of the modular body 20 is called the width direction and the length between the upper and lower parts of the modular body 20 is called the longitudinal direction, the width direction of the modular body 20 can be bent in the vertical direction.

Therefore, the area between both side ends of the modular body 20 and the bending rigid bar 234 are bent, and at the same time, the support bar 334 is also adjacent to each other in the left-right direction in a state in which the area between both ends is bent together. The connecting groove 22 and the connecting support piece 24 of one side end of each of the individual aggregate sorting screen modular arrangements are fitted into and coupled to the connecting support piece 24 and connecting groove 22 of the adjacent aggregate sorting screen modular. Therefore, it is easy and convenient when the connection grooves 22 and the connection support pieces 24 of the plurality of modular bodies 20 are fitted and coupled, and the support bar 334 is a bending rigid bar 234 and a modular body 20 inside. ) To increase the rigidity of the modular body 20 itself. Synergy that reinforces the structural strength of the aggregate sorting screen module itself due to the support bar 334 while increasing the convenience of connecting a plurality of aggregate sorting screen modules by enabling proper bending when connecting the aggregate sorting screen modules. The effect can be expected.

Further, in the present invention, the support bar 334 is provided with a plurality of holes 334H communicating on both sides. The side reinforcement bar 32 and the bending rigid bar 234 are embedded in a modular body 20 made of rubber, while the side reinforcement bar 32 and the bending rigid bar 234 are placed in a molding die in a liquid state. When the molded rubber liquid is filled with a plurality of holes 334H of the support bar 334 when the molded rubber liquid is injected into the mold, the molded rubber liquid is cured and then the support bar 334 A support pin portion filled in the holes 334H is formed, and the support pin portion becomes a structure connected to the interior of the modular body 20.

Therefore, the support bar 334 is more firmly embedded in the modular body 20 by a plurality of support pin portions filled in the plurality of holes 334H, and is filled in the plurality of holes 334H to provide a modular body ( Since the support bar 334 is prevented from being peeled off inside the modular body 20 by a plurality of support pins integrally connected to 20), the strength of the support bar 334 supporting the modular body 20 is weakened. This is also prevented.

In addition, the support bar 334 is built into the modular body 20 while the liquid rubber material for molding the modular body 20 is filled in each hole 334H of the support bar 334, so that it is supported in the molding mold. When the modular body 20 is molded by injecting a liquid rubber material in a state in which the bar 334 is put in, the support bar 334 is held in place without being displaced, so that the molding operation of the modular body 20 is performed. This is done correctly.

On the other hand, in the present invention, the side reinforcement bar 32 is provided with a bar coupling slit extending from the both ends to the center, and both ends of the support bar 334 can be fitted to the bar coupling slit.

In this case, the support bar 334 is formed when the modular body 20 is molded by injecting a liquid rubber material by inserting the side reinforcement bar 32, the bending rigid bar 234, and the support bar 334 into the molding die. The position disposed on the side reinforcement bar 32 is not displaced, so that the modular body 20 can be accurately formed.

In addition, the support bar 334 fitted to the bar coupling slit of the side reinforcement bar 32 can be joined to the side reinforcement bar 32 by welding, in which case the side reinforcement bar 32 and the support bar ( In the process of joining 334) by welding, the position of the support bar 334 is prevented from being displaced by the side reinforcement bar 32, so that the support bar 334 and the side reinforcement bar 32 can be more easily joined and joined. It prevents waste of joining work time due to displacement of positions during work.

On the other hand, the support bar 334 is provided with a connecting bracket piece, the connecting bracket piece can be fixed by a fastener to the side reinforcement bar 32, in this case the connecting bracket piece and side reinforcement of the support bar 334 Since the fastener can be released from the bar 32 and detached from the side reinforcement bar 32, the assembling operation of the support bar 334 and the side reinforcement bar 32 is more convenient.

In the above, specific examples of the present invention have been described above. However, the spirit and scope of the present invention is not limited to these specific embodiments, and various modifications and variations are possible within a range that does not change the gist of the present invention. Anyone who has it will understand it.
