Description

Aggregate screen blockage prevention device

The present invention relates to an aggregate sorting screen clogging prevention device, and more particularly, to an aggregate sorting screen clogging preventing device configured to apply a physical striking force to the vibrating vibrating screen to prevent clogging of the vibrating aggregate sorting screen.

A large amount of rubble is generated in the process of blasting a stone mountain for road construction or tunnel construction, or blasting a stone mountain to collect stones from a quarry. . For example, rubble is widely used in construction and construction fields such as asphalt pavement and building foundation construction. Therefore, in recent years, rubble is crushed 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.

Aggregate sorting devices and the like require a sorting vibrating screen through which the aggregates pass in order to sort the aggregates by size. An aggregate sorting vibrating screen provided in an aggregate sorting device, etc. is installed at an approximate inclination at the aggregate input end, and the aggregate is inputted and passed over the sorting vibrating screen, and at the same time, a vibration (vibration) is applied to the sorting vibrating screen to sort the aggregate. That is, the sorting vibrating screen is operated to vibrate and the aggregate is fed and passed over the sorting vibrating screen, so that the aggregate of a predetermined particle size passes through a plurality of sorting holes formed in the sorting vibrating screen and falls, so that the aggregate can be sorted. .

Aggregates are sorted and separated by particle size in an aggregate sorting device equipped with a vibrating screen. Aggregates smaller than the size of the aggregate sorting hole of the vibrating screen among the aggregates pass down through the vibrating screen, and aggregates larger than the size of the aggregate sorting hole proceed without passing through the vibrating screen, and the aggregates are classified according to their size.

However, in the process of crushing the aggregate when the aggregate is wet or raining, the powder of the cement component hydrates with water, and the aggregate selection hole of the vibrating screen of the aggregate separation device may be blocked. This clogging phenomenon often occurs when selecting aggregates to regenerate concrete.

In order to overcome this problem, conventionally, there is a case to prevent clogging of water by spraying a large amount of high-pressure water on the vibrating screen. In winter, there is a problem that watering is difficult.

On the other hand, there is a case to provide an aggregate sorting hole clogging prevention striking device of the vibrating screen for the aggregate sorting device, a plurality of non-powered striking rods are located on the upper surface of the vibrating screen. When the vibrating screen is vibrated by the vibrating means, the non-powered striking rod strikes the vibrating screen to break through the clogged aggregate sorting hole of the vibrating screen.

However, rather than the non-powered striking rod hitting the vibrating screen as a whole, only a part of the non-powered striking rod hits the vibrating screen, so the striking force of the striking rod is not transmitted effectively. there is

Referring to the drawings, the present invention is an aggregate sorting screen clogging prevention device installed in an aggregate sorting vibrating screen device in which a vibrating screen 22 having an aggregate sorting hole in the screen frame 12 is installed, and a striking support wire 32 and , and a striking strap 30 having a plurality of striking members 34 and striking spacers 36 coupled to the striking support wire 32 .

The percussion support wire 32 is a flexible, constant-length strap. That is, the hitting support wire 32 is a metal flexible strap. The hitting support wire 32 is configured as a flexible strap so that it can sway when a shaking force is applied by vibration or the like from the outside. In addition, both ends of the striking support wire 32 are provided with a closed loop wire portion. In a state in which the striking member 34 and the striking spacer 36 are inserted into the striking support wire 32, a portion of both ends of the striking support wire 32 is bent to form a closed loop wire part forming wire, and the closed loop When the wire forming wire and the striking support wire 32 are coupled to be fixed by a gripper, a closed loop wire portion is formed at both ends of the striking support wire 32 .

The striking member 34 is configured in the shape of a single tube of a certain length. The striking member 34 is configured in a circular single tube shape having a striking guide hole 35 therein. The striking guide hole 35 communicates with both ends in the interior of the striking member 34 . A striking support wire 32 is inserted into the striking guide hole 35 to form a structure in which the striking member 34 is coupled to the striking support wire 32 . A plurality of striking members 34 are coupled to the striking support wire 32 . When the striking support wire 32 is bouncing, the plurality of striking members 34 are also bouncing at the same time.

The striking spacer 36 is configured in the shape of a single tube having a predetermined length. The striking spacer 36 is configured in a circular single tube shape having a spacing hole 37 therein. The striking support wire 32 is inserted into the spacing hole 37 to form a structure in which the striking spacer 36 is coupled to the striking support wire 32 . The striking spacer 36 is disposed between the two striking members 34 . A plurality of striking support wire-air striking spacers 36 are coupled and at the same time one striking spacer 36 is disposed between the two striking members 34 . When the striking support wire 32 is bouncing, the plurality of striking spacers 36 together with the plurality of striking members 34 are also sloshed together. At this time, the outer diameter of the striking spacer 36 is smaller than the outer diameter of the striking member 34, there is a height difference between the outer peripheral surface of the striking spacer 36 and the outer peripheral surface of the striking member (34).

A plurality of striking members 34 and striking spacers 36 are coupled to the striking support wire 32 to constitute a striking strap 30, and the striking strap 30 is installed on the screen frame 12 in a plurality of rows. do. The screen frame 12 is provided with a connecting member such as a ring-shaped connecting member or a pin on support bars arranged in parallel with each other, and the closed loop wire portions provided at both ends of the striking support wire 32 are connected to the connecting member. , the striking strap 30 is arranged in a plurality of rows side by side on the screen frame (12). The plurality of rows of striking straps 30 are disposed on the vibrating screen 22 supported on the screen frame 12 , and configured so that the striking member 34 can strike on the vibrating screen 22 .

According to the present invention of the above-described configuration, the screen frame 12 on which the vibrating screen 22 is supported is installed at an angle, and the aggregate enters from the input end of the screen frame 12 installed at an angle and flows downward. The direction indicated by the arrow in the drawing is the flow direction of the aggregate.

When the aggregate enters the screen frame 12 on which the vibrating screen 22 is supported and flows downward, the screen frame 12 and the vibrating screen 22 move in the front and rear left and right directions by a vibration driving device such as a vibrating motor to vibrate. When the striking strap 30 also vibrates on the vibrating screen 22 by vibration, a plurality of striking members 34 hit the vibrating screen 22 from above to block the aggregate sorting hole of the vibrating screen 22. By shaking off the clogging of the vibrating screen 22 is prevented.

In addition, since the outer diameter of the plurality of striking members 34 and the outer diameter of the striking spacer 36 are different, the force at which the striking member 34 strikes the vibrating screen 22 can be increased due to the height difference, so the vibrating screen 22 ), the operation of brushing off the aggregate blocking the aggregate sorting hole is more smoothly and reliably performed. The striking force of the striking strap 30 is more efficient as the striking strap 30 in which the plurality of striking members 34 and the striking spacer 36 are coupled to the striking support wire 32 hits the vibrating screen 22 as a whole. is transmitted to the vibrating screen 22, so the vibrating screen 22 can shake off the aggregate from all the aggregate sorting holes, and in particular, has the effect of easily drilling the clogged aggregate sorting hole in the center of the vibrating screen 22 . Because the outer diameter of the plurality of striking members 34 and the outer diameter of the striking spacer 36 are different, the force at which the striking member 34 strikes the vibrating screen 22 is increased due to the height difference, while the plurality of striking members 34 vibrate Since the vibrating screen 22 is not hit only a part of the screen 22, the vibrating screen 22 is hit as a whole, and the striking spacer 36 is also swaying and adding a striking force to the vibrating screen 22, so the striking strap 30 As the striking force of the vibrating screen 22 is transmitted more efficiently to the vibrating screen 22, it is possible to shake off the aggregate without omission from all the aggregate sorting holes of the vibrating screen 22.

In addition, in the present invention, since it is only necessary to insert the striking member 34 and the striking spacer 36 having a relatively small diameter to the striking support wire 32, it is easier to manufacture and has the effect of further simplifying the work process.

On the other hand, as shown in FIG. 5, in the present invention, the striking member 34 and the striking spacer 36 are inserted into the striking support wire 32 by the striking guide hole 35 and the spacing hole 37, respectively. , The striking guide hole 35 inside the striking member 34 is configured to include a tapered striking guide hole 35A on both sides with respect to the center between both ends of the striking member 34 . One taper striking guide hole (35A) is configured such that the inner diameter gradually widens from the center line between the both ends of the striking member (34) toward one end of the striking member (34), the other tapered striking guide hole (35A) ) is configured such that the inner diameter gradually widens from the center line between both ends of the striking member 34 toward the other end of the striking member 34 .

When the striking guide hole 35 is composed of both left and right taper striking guide holes 35A, the striking support wire 32 when the striking support wye and the striking member 34 sway by vibration, etc., the striking member as a reference As the 34 moves up and down more than in the case of the straight-type striking guide hole 35, the force at which the striking member 34 strikes the vibrating screen 22 becomes larger, so that the aggregate in the vibrating screen 22 is It is possible to more reliably prevent the clogging of the vibrating screen 22 by shaking off the aggregate blocking the sorting hole.

When the striking support wire 32 and the striking member 34 and the striking spacer 36 sway upward, the striking support wire 32 is a pair of tapered striking guides at the longitudinal centerline of the striking member 34 . By the inclined surface of the hole 35A, the striking member 34 moves higher than the striking support wire 32, and the striking support wire 32, the striking member 34, and the striking spacer 36 move downward. When sloshing, the striking support wire is lower than the striking support wire 32 by the inclined surface of the pair of tapered striking guide holes 35A at the longitudinal centerline of the striking member 34. As the moving distance increases while the striking member 34 sways above the vibrating screen 22, the striking member 34 hits the vibrating screen 22 with a greater force. Accordingly, the vibrating screen 22 will more reliably shake off the aggregate blocking the aggregate sorting hole.

In addition, as shown in FIG. 8 , in the present invention, the opposite ends of the striking member 34 and the striking spacer 36 are each composed of a striking guide inclined end 38 and a spacer inclined end 39 .

The striking guide inclined end 38 is configured to have a pair of striking guide inclined portions symmetrical with respect to the longitudinal centerline of the striking member 34 . The pair of striking guide inclined portions are configured as curved surfaces.

In addition, the spacer inclined end portion 39 is configured to include a pair of spacer inclined portions symmetrical with respect to the longitudinal centerline of the striking spacer 36 . The pair of spacer slopes is configured as a curved surface.

Therefore, as shown in FIGS. 9 and 10 , the striking guide inclined portion and striking of the striking member 34 when the striking support wire 32 , the striking member 34 and the striking spacer 36 sway together. Since the striking member 34 and the striking spacer 36 sway together with the striking support wire 32 in a state in which the force colliding with the spacer inclined ends 39 of the spacer 36 does not act, the striking member 34 and the striking spacer 36 sway together. (34) and the striking spacer 36 have an effect of preventing the end contacting each other from being damaged by a collision force, and the striking member 34 and the striking spacer 36 sway independently of each other at the moment of sloshing. As a result, the striking member 34 also acts to add a force to hit the vibrating screen 22, so that the striking member 34 hits the vibrating screen 22 with a greater force as much as the aggregate in the vibrating screen 22. It also has the effect of more reliably removing the aggregate blocking the sorting hole.

On the other hand, as shown in FIG. 13, in the present invention, although the taper striking guide hole 35A is formed inside the striking member 34, the diameter of the tapered striking guide hole 35A is the aggregate in the striking member 34. is configured to become increasingly larger from the end facing the flowing down direction toward the opposite end. The taper striking guide hole (35A) is configured in the shape of a fallopian tube hole that gradually becomes larger toward the opposite end from the end in the direction in which the aggregate flows down from the striking member (34). In the striking member 34, the end in the direction in which the aggregate flows down is referred to as a first end, and the end opposite to the first end is referred to as a second end, the diameter of the taper striking guide hole 35A is the striking member (34) is configured to become increasingly larger from the first end toward the second end.

The screen frame 12 is inclined, and the aggregate is inclined from the upper end to the lower end of the screen frame 12 (that is, the lower end of the aggregate sorting side has a lower height than the upper end of the aggregate input side). The aggregate enters from the upper end of the screen frame 12 and flows toward the lower end of the screen frame 12 to sort the aggregate, and at the end facing in the direction in which the aggregate flows in the striking member 34, taper striking guide hole 35A) There is no floating space between the outer circumferential surface of the striking support wire 32 and the striking member 34, and the diameter of the tapered striking guide hole 35A increases from the end in the direction in which the aggregate flows in the striking member 34 toward the opposite end. made to grow.

In this case, the striking member 34 is relatively higher up and down by the tapered striking guide hole 35A as compared to that in which the striking guide hole 35 having a straight hole shape is formed inside the striking member 34. Thus, while more reliably preventing the case where the aggregate sorting hole of the vibrating screen 22 is blocked by the aggregate, the striking member 34 has a tapered striking guide hole 35A and a striking support wire ( 32), it is possible to prevent the penetration of aggregates between the outer peripheral surfaces.

14 and 15, the taper striking guide hole (35A) of the striking member (34) and the striking support wire (32) from the end side facing the direction in which the aggregate of the striking member (34) flows down Aggregate penetrates into the space created between the outer circumferential surfaces, and when the aggregate penetrates into the space, there is room for breakage of the striking support wire 32 by the aggregate, but as described above, toward the direction in which the aggregate flows from the striking member 34 At the end with the tapered striking guide hole (35A) and the outer peripheral surface of the striking support wire (32), there is no space, which is a raised space, from the end toward the opposite end in the direction in which the aggregate flows in the striking member (34). Since the diameter of the guide hole (35A) is configured to become larger and larger, the taper strike guide hole (35A) and the outer circumferential surface of the striking support wire (32) at the end toward the direction in which the aggregate flows in the striking member (34) between the aggregate It is possible to prevent in advance the breakage of the striking support wire 32 by the aggregate by preventing the penetration of the striking member 34, and it is also possible to prevent the case where the striking member 34 is rapidly worn by the aggregate penetrated into the interior. .

In addition, as shown in FIGS. 11 and 12, in the present invention, the striking guide hole 35 inside the striking member 34 is tapered on both sides with respect to the center between both ends of the striking member 34. 35A), the outer diameter of the striking spacer 36 is always configured with a diameter that can block the space generated between the tapered striking guide hole 35A and the striking support wire 32 .

The screen frame 12 is inclined, and the aggregate is inclined from the upper end to the lower end of the screen frame 12 (that is, the lower end of the aggregate sorting side has a lower height than the upper end of the aggregate input side). The aggregate enters from the upper end side of the screen frame 12 and flows toward the lower end of the screen frame 12 to sort the aggregate, wherein the striking member 34 and the striking spacer 36 sway with the striking support wire 32 A space to be lifted is generated between the inner circumferential surface of the data striking guide hole 35A of the striking member 34 and the outer peripheral surface of the striking support wire 32 at an instant. In the process of sorting the aggregate as the aggregate flows from the upper end to the lower end of the screen frame 12, the striking member 34 and the striking spacer 36 sway with the striking support wire 32 at the moment when the striking member 34 sways. When a space is raised between the inner peripheral surface of the tapered striking guide hole 35A and the outer peripheral surface of the striking support wire 32 of A space is formed between the inner peripheral surface of 35A and the outer peripheral surface of the striking support wire 32 . If the end of the striking member 34 in the direction in which the aggregate flows down is referred to as the first end, and the end opposite to the first end is referred to as the second end, the aggregate from the upper end of the screen frame 12 to the lower end is referred to as the lower end. The taper striking guide hole inside the first end side of the striking member 34 at the moment the striking member 34 and the striking spacer 36 sway with the striking support wire 32 in the process of sorting the aggregate while flowing down. (35A) The space is generated between the inner circumferential surface and the outer circumferential surface of the striking support wire 32, while the tapered striking guide hole 35A inside the second end side of the striking member 34 and the outer circumferential surface of the striking support wire 32 There is also space between them.

At this time, the inner circumferential surface of the taper striking guide hole 35A inside the second end side opposite to the end side (ie, the first end side) facing the direction in which the aggregate flows down from the striking member 34 and the striking support Even if there is a space that is a space away from the outer circumferential surfaces of the wire 32, the aggregate just flows down, but the end side (that is, the first end side) facing the direction in which the aggregate flows down from the striking member 34 inside If the space between the inner peripheral surface of the tapered striking guide hole 35A and the outer peripheral surface of the striking support wire 32 is spaced apart from the end side facing the direction in which the aggregate of the striking member 34 flows down, the striking member ( 34), the aggregate penetrates into the space formed between the taper striking guide hole 35A of the striking member 34 and the outer peripheral surface of the striking support wire 32 from the end side facing the direction in which the aggregate flows down, and into the space When aggregate penetrates, there is room for breakage of the strike support wire 32 by the aggregate.

However, as shown in FIG. 12 , in the present invention, the outer diameter of the striking spacer 36 is the taper striking guide hole at the moment when the striking member 34 and the striking spacer 36 sway with the striking support wire 32 . (a space formed between the taper striking guide hole 35A inside the first end side of the striking member 34 and the striking support wire 32 on the side) generated between the 35A and the striking support wire 32 It consists of a given diameter. For example, if the space is 5 mm at the moment when the striking member 34 and the striking spacer 36 sway with the striking support wire 32, the radius of the striking spacer 36 is 5 mm or more and the striking spacer 36 is configured to have an outer diameter of 10 mm or more.

Therefore, the end facing the direction in which the aggregate flows down from the striking member 34, that is, the inner peripheral surface of the taper striking guide hole 35A inside (that is, the first end side) and the outer peripheral surface of the striking support wire 32. Since the striking spacer 36 blocks the space, which is a space, at the end side facing the direction in which the aggregate of the striking member 34 flows down, the end side facing the direction in which the aggregate of the striking member 34 flows down. Prevents the aggregate from penetrating into the space created between the taper striking guide hole 35A of the striking member 34 and the outer peripheral surface of the striking support wire 32, thereby supporting the striking by the aggregate penetrating into the space Prevents the wire 32 from breaking.

In addition, as shown in Figure 16, in the present invention, the outer peripheral surface of the striking member 34 is configured as a curved surface. When the outer peripheral surface of the striking member 34 is formed of a curved surface, the striking member 34 and the striking spacer 36 sway together with the striking support wire 32 to shake off the aggregate from the aggregate selection hole of the vibrating screen 22 . The center between both ends of the striking member 34 strikes the vibrating screen 22 with a concentrated force when taking out, so that the efficiency of shaking off the aggregate from the vibrating screen 22 can be further increased, while the striking member 34 is moved to the vibrating screen 22 ) is also prevented from being quickly worn due to the accumulated striking force and has the effect of further extending the life of the striking member 34 .
