Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of road construction and relates to a screening device, in particular to a simple screening device for crushed stones. Background Art
[0002] In the construction of highways and municipal roads, crushed stone or unscreened crushed stone is commonly used for soft soil foundation replacement, structure cushion, platform backfill and other materials. The particle size of crushed stone is often determined by the production equipment of the processing plant. However, for the construction of roads in special areas and sections, the requirements for the particle size of crushed stone are different.
[0003] At present, before construction, it is necessary to specially purchase the required multiple specifications of crushed stone materials in combination with the particularity of the construction site and the amount of materials used. The procurement of multiple specifications of crushed stone materials is difficult to transport and has a long cycle. Compared with the on-site storage of single-specification materials, it occupies a large area and has high costs, and has a certain impact on the construction period. Summary of the invention
[0004] The utility model aims to provide a simple crushed stone screening device which has a scientific and reasonable structural design, reduces the cost of crushed stone transportation, is convenient for crushed stone storage, is convenient for operation and is easy to implement.
[0005] The utility model solves the technical problem through the following technical solutions:
[0006] A simple screening device for crushed stone is characterized by comprising a frame, a spring, a screen, a screen mounting frame, a motor bracket and a vibration motor, wherein the screen mounting frame is mounted on the upper end surface of the frame via a spring, a screen is laid in the screen mounting frame via screws, a motor bracket is mounted on the screen mounting frame, and a vibration motor is mounted on the motor bracket.
[0007] Moreover, the frame includes front legs, rear legs, connecting rods and brake wheels. The two front legs are arranged side by side in the front, and rear legs are arranged opposite to each other at the rear of the two front legs. The height of the rear legs is higher than that of the front legs. Connecting rods are connected between the front legs, between the front legs and the rear legs, and between the rear legs and the rear legs, and brake wheels are installed at the bottom of the front legs and the rear legs.
[0008] Moreover, it also includes a pushing mechanism, which includes a mounting plate, a driving cylinder and a bulldozer. The mounting plate is installed between the two front legs, the driving cylinders are symmetrically installed on both sides of the back of the mounting plate, and the bulldozer is connected to the cylinder rods of the two driving cylinders.
[0009] The advantages and beneficial effects of the utility model are:
[0010] This simple screening device for crushed stone can effectively screen crushed stone particles, and only requires a loader to work. The use of this simple screening device for crushed stone can avoid the problems of high cost and large space caused by transporting and stacking crushed stones of different specifications separately. Since a pushing mechanism is arranged under the screen, the screened crushed stone does not accumulate under the screen and can work continuously. A brake wheel is arranged under the device, and the equipment can be moved at any time, which can better achieve the purpose of screening. In special areas and special sections where it is difficult to purchase, transport and store crushed stone materials of multiple specifications, it can effectively control the particle size of the crushed stone, ensure the construction quality, reduce costs and speed up the progress of the project.

[0015] The present invention will be further described in detail below through specific embodiments. The following embodiments are only descriptive and not restrictive, and the protection scope of the present invention cannot be limited by them.
[0016] A simple screening device for crushed stone, the innovation of which lies in: comprising a frame, a spring 6, a screen 3, a screen mounting frame 2, a motor bracket 4 and a vibration motor 5, a screen mounting frame being mounted on the upper end surface of the frame by means of a spring, a screen being laid in the screen mounting frame by means of screws, a size of the screen mounting frame being 5m*4m (length*width), an aperture of the screen being determined according to actual demand, a motor bracket being mounted on the screen mounting frame, and a vibration motor being mounted on the motor bracket.
[0017] When in use, a suitable screen is installed on the screen installation frame according to the particle size of the gravel to be screened, the loader unloads the material, and the vibration motor starts working, thereby completing the vibration unloading.
[0018] In order to make the gravel dropped from the loader evenly distributed on the screen, the utility model designs the screen as an inclined structure, that is, the frame includes a front leg 1, a rear leg 7, a connecting rod 8 and a brake wheel 9, the front leg and the rear leg are both cylindrical steel uprights with a diameter of 10 cm, the spring and the steel upright are fixed with bolts, the two front legs are arranged side by side in the front, and the rear legs are relatively arranged at the rear of the two front legs, and the height of the rear legs is higher than the front legs. This front low and rear high structure makes the screen inclined thereon, with an inclination angle of 45°, connecting rods are connected between the front legs and the front legs, between the front legs and the rear legs, and between the rear legs and the rear legs, and brake wheels are installed at the bottom of the front legs and the rear legs to facilitate the movement of the device.
[0019] In order to avoid the problem that the screened gravel is accumulated under the screen and affects the screening efficiency, the utility model also designs a pushing mechanism, which includes a mounting plate 10, a driving cylinder 11 and a bulldozer 12. A mounting plate is installed between the two front legs, driving cylinders are symmetrically installed on both sides of the back of the mounting plate, and bulldozers are connected to the cylinder rods of the two driving cylinders. The bulldozer is the same width as the screen, which is convenient for pushing the screened gravel that meets the required particle size out of the device at a regular time without affecting the subsequent screening.
[0020] Construction process
[0021] 1. The crushed stone is unloaded to the designated location after entering the site by a transport vehicle, and a simple screening device for the crushed stone is set up at the unloading location;
[0022] 2. Use a loader to load the material, turn on the vibration motor, and pour the crushed stone onto the screen for screening;
[0023] 3. The gravel that meets the requirements falls through the screen and is transported out of the screen through the pushing mechanism;
[0024] 4. During screening, particles that do not meet the requirements will slide to the other side along the slope of the screen;
[0025] 5. Use a loader to promptly and separately transport qualified gravel to complete screening.
[0026] Although the embodiments and drawings of the present invention are disclosed for illustrative purposes, those skilled in the art will appreciate that various substitutions, changes and modifications are possible without departing from the spirit and scope of the present invention and the appended claims. Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
