The connecting rod 13 must be spaced apart from the inner surface of the ring 12 so as not to restrict the operation of the scraper 20 that eliminates the blockage of the selection hole 11 while passing through the selection hole 11 of the trommel 10. And, for this purpose, it is fixed to the ring 12 through the leg 14.

When the trommel 10 rotates and passes through the scraper protrusion 22 of the scraper 20, the scraper protrusion 22 passes through the sorting hole 11 between the rings 12 The connecting rod 13 is spaced apart from the ring 12 so that the soil accumulated inside the sorting hole 11 is also separated from the ring 12.

Both sides of the leg 14 must be connected to the ring 12 and the connecting rod 13, respectively, and in that way, one side is welded to the ring 12 and the other side is a connecting rod ( There is a method of welding to 13), a method in which the ring 12 or the connecting rod 13 is integrally formed (comb pattern) and the free end is fixed to the connecting rod 13 or the ring 12.

According to this configuration, the connection rod 13 also functions to keep the spacing of the rings 12 constant.

Only one connecting rod 13 may be used for fixing the rings 12, or two or more may be spaced apart from each other at a predetermined distance along the circumferential direction.

The trommel 10 is not limited to using a ring 12 completed in a circular shape, and a plurality of straight rods are fixed with a connecting rod 13 to manufacture a comb-shaped plate, and the plate is rolled in a circular shape, It can also be manufactured by a method of fixing both ends, and fixing of both ends is also possible by means of the connecting rod 13.

In addition, one or two or more trommels 10 are connected and used, and two or more connections are made by the aforementioned connecting rod 13.

The trommel 10 is rotatably supported on the frame and rotates through a rotating means to enable selection using all parts of the selection hole 11, and the rotating means is, for example, a motor fixed to the frame, Consisting of a power transmission means for transmitting the rotational force to the trommel 10, the power transmission means is a sprocket connected to a drive sprocket coupled to the drive shaft of the motor and a driven sprocket coupled to the circumference of the trommel 10 I can.

In the present invention, since the spacing of the rings 12 is the sorting hole 11, the size of the sorting hole 11 can be freely adjusted by adjusting the spacing of the rings 12, and thus, various It is possible to configure a sorting hole 11 of a size, for example, increasing the size of the sorting hole 11 while going from the hopper 1 to the discharging end of the opposite side, forming a sorting section of different sizes is very It's easy.

The scraper 20 is formed protruding from the fixing part 21 and the fixing part 21 along the sorting hole 11 at a certain distance from each other and inserted into the sorting hole 11 to eliminate the clogging of the sorting hole 11 It includes a plurality of scraper protrusions (22).

The fixing part 21 is fixed to the frame while being arranged long along the longitudinal direction of the trommel 10 at the periphery of the trommel 10, and the fixing is preferably fixed by a detachable bolt and nut. The frame is supported on the ground while covering the periphery of the trommel 10 in order to prevent scattering and loss of soil, for example.

The fixing part 21 may be a flat plate, or a curved plate that is the same or similar to the shape of the trommel 10, that is, the shape of the ring 12.

The scraper protrusion 22 protrudes on one side of the fixing part 21, that is, the side facing the trommel 10, and its length is inserted into each of the sorting holes 11 of the trommel 10, so that the free end thereof is the ring 12 It is a length that penetrates into the trommel 10 by being spaced apart from the inner surface of.

The scraper protrusion 22 may be of various shapes such as a plate shape and a rod shape, and is preferably used in the same quantity as the selection hole 11 along the direction of the selection holes 11, that is, the lengthwise direction of the fixing part 21.

The scraper protrusions 22 may be in one row or two or more rows.

The present invention may include an entry induction portion 30 and an entry induction portion 40 on one or more of both sides in the longitudinal direction of the trommel 10.

The entry induction portion 30 and the entry induction portion 40 are each cylindrical without holes and are fixed to the entry portion and the exit portion of the trommel 10 by welding or the like.

The entry induction part 30 is a part into which aggregates (soil and foreign matter) are introduced through the hopper 1 and there is no hole, so all aggregates supplied from the hopper 1 are supplied to the trommel 10 after a certain period of time.

The advancing induction part 40 is a part for discharging the soil powder from which foreign substances are selected in the trommel 10, and induces rapid discharge of the soil powder selected from the foreign substances.

In the drawings, unexplained reference numeral 2 denotes a product conveyor that collects or transports products (soil) falling from the discharge end of the trommel 10, and 3 denotes foreign matter falling through the sorting hole 11 of the trommel 10 It is a foreign material conveyor that collects or transports.

The sediment sorting device for aggregates to eliminate clogging of the sorting hole according to the present invention can be either a fixed type fixed to the aggregate treatment site or a movable type mounted on a vehicle and used while moving.

The method of sorting the soil powder of the aggregate to eliminate blockage of the sorting hole according to the present invention is as follows.

1. Trommel drive and aggregate input.

The trommel 10 is rotated by turning on the rotating means, and, for example, the aggregate that has passed through the vibrating screen is injected into the trommel 10 through the hopper 1.

The aggregate falls on the entry guidance unit 30 and is dispersed while passing through the entry guidance unit 30.

2. Foreign matter screening.

The aggregate that has passed through the entry induction part 30 is introduced into the trommel 10 and transferred to the discharge end of the trommel 10, and in this process, the selection hole 11 is passed through the selection hole 11 of the trommel 10. Foreign matter having a particle size smaller than the size of) passes through the sorting hole 11 and is discharged to the bottom.

At this time, since the sorting hole 11 is continuous without disconnection along the circumferential direction, foreign substances are sorted through all parts of the sorting hole 11, and there is no part blocking the sorting hole 11, so It fundamentally solves the accumulation of foreign matter.

In addition, while the trommel 10 is rotating, it passes through the scraper 20, which is a fixed body, and the scraper protrusion 22 of the scraper 20 passes through the selection hole 11 of the trommel 10 to penetrate the trommel. 10), and the free end is disposed inside the ring 12, so when the trommel 10 rotates, the sorting hole 11 passes through the scraper protrusion 22. Foreign substances that are fixed to the ring 12 of the rommel 10 and block the sorting hole 11 are removed from the ring 12 by the scraper protrusion 22 to eliminate the clogging of the sorting hole 11.

The scraper protrusion 22 is capable of not only solving the clogging of the sorting hole 11, but also hitting (shaking) and dispersing the aggregate in the trommel 10, thus inducing a phenomenon of dropping foreign substances.

During this process, foreign substances having a size smaller than that of the sorting hole 11 pass through the sorting hole 11 and fall on the foreign matter conveyor 3 below to be sorted.

3. Product discharge.

The soil powder passes through the trommel 10 and is transferred to the advancing induction part 40 and is discharged after passing through the advancing induction part 40. At this time, the remaining foreign matter may fall from the advance induction part 40.

Hereinafter, another example of the configuration applied to the present invention will be described.

In the present invention, the scraper protrusion 22 does not scratch only the outer surface of the trommel 10, but penetrates through the selection hole 11 and is inserted into the trommel 10 so that the inner surface of the selection hole 11 is not blocked. Therefore, it is preferable to install the scraper protrusion 22 at an optimal position even if the thickness of the ring 12 is varied by adjusting the length of the portion inserted into the trommel 10.

Methods of adjusting the position of the scraper protrusion 22 include a method in which the scraper protrusion 22 is assembled to the fixing part 21 so as to be able to move forward and backward, and a method that the scraper protrusion 22 is mounted to the frame so that it can be moved back and forth .

4 shows an example in which the scraper protrusion 22 is moved forward and backward when the fixing part 21 is used as the fixing part. For example, a nut 23 is installed on the fixing part 21 and the scraper protrusion ( Assemble 22) to the nut 23 by screwing and adjust the position of the scraper protrusion 22. Here, the fixing part 21 is configured so that the rear of the nut 23 is also opened, so that the scraper protrusion 22 may protrude to the rear of the fixing part 21.

In the case of fixing the scraper protrusion 22 to the fixing part 21, the fixing part 21 is installed in a frame so as to move forward and backward, and the method is possible through the above-described method, so a detailed description thereof will be omitted.

In addition, a plurality of scraper protrusions 22 are each configured as a detachable assembly type to the fixing part 21, and at this time, even if the scraper protrusions 22 are inserted into the trommel 10 and used, the fixing part 21 is framed. The scraper protrusion 22 is configured to be assembled from the outside of the fixing part 21 so that only the scraper protrusion 22 can be separated without separating it from, for example, the scraper protrusion 22 outside the fixing part 21 It is possible to insert the scraper protrusion 22 to the fixing part 21 through a fastener such as a lock nut or a pin from the outside of the fixing part 21 by inserting it into the hole formed in the fixing part 21 from the side.

In the case of the assembly type of the fixing part 21 and the scraper protrusion 22, as shown in FIG. 5, a plurality of scraper protrusions 22 are assembled to one assembly plate 24, and the assembly plate 24 is fixed It is also possible to fix the fasteners 25 (bolts and nuts, etc.) to 21, and according to this method, maintainability is achieved by replacing only the scraper protrusion 22 alone while using the fixing part 21 as it is. It is possible to improve and it is very easy to work by installing a plurality of scraper protrusions 22 through a single operation of the assembly plate 24.

In this case, assembling and disassembling the assembly plate 24 from the outside of the fixing portion 21, and installing a coil spring on the fastener 25 to elastically move the assembly plate 24 to the fixing portion 21 It can be easily applied to install so as to.

In addition, the scraper protrusion 22 may be configured such that elastic behavior is possible in the fixing part 21, and the scraper protrusion 22 has the free end of the trommel 10 at the initial position before the aggregate is input. It is installed so as to receive the support of the coil spring installed on the fixed part 21 while the opposite side is positioned further inside the ring 12 than the inner surface.

The connecting rod (13) allows the scraper protrusion (22) to be disposed more inward than the inner surface of the ring (12) and is spaced from the inner surface of the ring (12) through the leg (14), but in a direction crossing the rings (12). Since the soil is arranged in a manner, soil powder may be accumulated, and in order to more effectively eliminate the soil powder accumulation therein, one or more through holes 13a may be included in the connection rod 13.

The through hole 13a may function as a welding hole when fixing the leg 14 by welding while having a function of preventing soil powder from passing through.
