Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a crushed stone classifier.

[0002]

[Prior art]

 The crushed stone soil generated during house demolition work and civil engineering work is currently transported to landfills for landfill because there is no cheap, convenient, and efficient sorting machine. .

[0003]

[Problems to be solved by the invention]

 In view of the current situation described above, the present invention aims to provide a crushed stone classifier that is easy to carry to the work site, that can be manufactured at low cost, and that enables efficient classification. is there.

[0004]

[Means for Solving the Problems]

 According to the present invention, a rectangular parallelepiped frame is formed, and at least two large spaces are formed using a horizontal partition frame, and the scale of the space is reduced from above to below. Vibration motors should be attached to the lower sieve box with the standard sieve boxes stacked in two stages, and a pair consisting of these units should be arranged obliquely to each other at a fixed inclination angle. It is characterized by.

[0005] At this time, the sieve mesh of the sieve box has a thickness of 2 cm to 5 cm of the steel plate material, and the surface area and the back area area of the sieve are smaller than those of the former. Large cross-section Wedge-shaped side surface is excellent in preventing clogging effectively, and a variable level machine was used on the bottom side via a mount for installation of each structural unit If this is done, it will be excellent in terms of work because efficient propagation of vibration and easy change of the inclination angle can be easily performed.

[Embodiment of the invention]

 FIG. 1 is a side view of the device of the present invention, FIG. 2 is a partially detailed portion showing formation of a sieve mesh of a sieve box, and FIG. 3 is a plan view taken along line xx of FIG. In each figure, 1 is a rectangular frame, and 2 is a hopper placed above the sieve. A sieve box for classifying and sorting the crushed stone soil put into the hopper 2 is placed in the frame. It is provided by the following configuration.

[0007] Reference numerals 3a and 3b denote horizontal partition frames provided in the frame, whereby at least two large spaces 1a and 1b are formed in the frame. Reference numerals 4, 5, 6 and 7 denote sieve boxes disposed in the spaces 1a and 1b, the grades of which are reduced in order from the upper sieve box 4 to the lower sieve box. Further, in the present invention, the sieve boxes 4, 5, 6, and 7 are each placed in a two-stage overlapping state by using the opposing pedestals 8, so that the opposing pedestals 8 are locked at the same height. Is provided.

[0008] In the present invention, the sieve box having the lower scale smaller than that of the upper sieve as described above is formed into a pair of parallel two-stage stacks by using the gantry 8 and each pair of lower sieve boxes is The vibration motor 9 is mounted in a frame as a structural unit for mounting the vibration motor 9, and a variable level machine 11 is mounted on a bottom surface of the gantry 8 via a mount 10. Thus, the variable level machine 11 is designed for the convenience of obtaining a constant inclination angle.

Although the above is the arrangement with respect to the space 1a, the sieve boxes 6 and 7, which are the same constituent units, are also arranged with respect to the space 1b. And the direction of the flow of the sorted material can be changed. In the drawing, reference numeral 12 denotes a guide plate for receiving the sorted material classified by the sieve box 5 and dropping it to the upper end side of the sieve box 6, and 13, 14, 15, and 16 denote the respective sieve boxes. Discharge chutes arranged at the lower ends of 4, 5, 6 and 7 for taking out the classified material from each sieve box to the outside. Reference numeral 17 denotes a chute for discharging the final residual soil disposed below the sieve box 7.

In the present invention, the sieve of each sieve box is formed by punching a steel plate having a thickness of 2 cm to 5 cm into a sieve having an appropriate size. From the point of recycling of crushed stone soil, it is intended to cover stones of about 5 cm or less in outer diameter, so that sieve 4 is assumed to be capable of passing about 5 cm of stone, and sieve box 5 is capable of filtering small stones of about 3 cm. The sieve box 6 is intended to pass granules of about 1 cm in size, and the sieve box 7 is to allow the remaining sand to fall, and at that time, as shown in FIG. The side surface shape of each eye is formed so as to have a wedge-shaped cross-section so that the product s and the back side s ′ have a relationship of s <s ′. This is very effective in improving the passage of sorted items and preventing blinding.

[0011] The classification and sorting machine of the present invention makes it possible to efficiently obtain equivalent stones such as chestnut stones and pebbles from crushed stone soil generated at construction sites such as houses and buildings. From the discharge chute 15, pebble equivalent stones are obtained, and from the discharge chute 16, granules of about 1 cm are obtained. When the direction of the discharge chute is constant in the above-mentioned removal, it is convenient to mount the discharge chute rotatable about 180 ° as shown in FIG. In the drawing, reference numeral 18 denotes a bearing pin, and 19 denotes a bearing member protruding from the frame side.

Next, the operation will be described. When the power of the vibration motor is turned on, the crushed stone soil is put into the hopper 2 under the vibrating state of each sieve box. And falls on the sieve box 5. At this time, the crushed stone that does not pass through the sieves of the sieve box 4 is taken out from the lower end edge of the sieve box through the discharge chute 13 and falls onto the sieve box 5 to pass through the sieves. The crushed stones that are not removed are extracted as chestnut stones through the discharge chute 14 to the outside.

On the other hand, the crushed stone soil that has passed through the sieves of the sieve box 5 falls onto the guide plate 12 and is guided by this to drop to the upper end side of the sieve box 6. Those that do not pass through the sieve are taken out of the discharge chute 15 as pebbles, while those that pass are dropped onto the sieve box 7. Those that do not pass through the sieves of the sieve box 7 are taken out through the discharge chute 16 as granules. On the other hand, the earth and sand passing through the sieves of the sieve box 7 is discharged outward by a discharge chute 17 disposed below the sieve.

[0014]

[Effect of the invention]

 The present invention is constructed as described above, and the sieve box with the sieve mesh reduced from above is made into a two-tiered pair with a special stand, and this is a compact overall structure that vibrates integrally. Therefore, it is easy to manufacture and inexpensive, and it is easy to carry and can be moved at the site as needed, and efficient sorting and classification of construction stones and crushed stones can be obtained. Therefore, it is important to collect all the crushed stones that can be used in the past, and to contribute to the promotion of crushing and recycling of the remaining soil, which had been exclusively used for landfill and submerged investment.
