Description

Technical Field

[0001] This utility model relates to the field of building aggregate technology, and in particular to a sand sorting machine for aggregate production. Background Technology

[0002] Sand and gravel aggregates are one of the important raw materials in various infrastructure projects such as bridges, highways, railways, and housing construction. They play a role in the skeleton and support of buildings. Fine aggregates refer to aggregates with a particle size of less than 4.75 mm, also known as sand. Fine aggregates can be further divided into coarse sand, medium sand, fine sand, and extra-fine sand.

[0003] Sand sorting machines are typically used to screen out impurities such as stones from sand. They are an indispensable tool in construction engineering. Currently, sand sorting in engineering mainly relies on screens, with manual labor involving continuous loading and unloading with shovels, which increases the labor intensity for workers.

[0004] Therefore, we need to design a sand sorting machine for aggregate production. Utility Model Content

[0005] In order to overcome the shortcomings of current engineering sand selection methods that mainly rely on sieves and require manual shovel loading and unloading for screening, which increases the labor intensity of workers, this utility model aims to provide a sand selection machine for aggregate production.

[0006] To solve the above-mentioned technical problems, this utility model provides a sand sorting machine for aggregate production, including a support frame, a machine body, a screen, a feed inlet, a discharge outlet, a filter frame, a buffer block, a second motor, and a power rod. The machine body is mounted on several support frames. The feed inlet is provided at the top of the machine body, and a screen is installed inside the feed inlet. The discharge outlet is provided at the bottom of the machine body. A filter frame is installed inside the machine body, and a buffer block is installed on the filter frame. The second motor is installed in the buffer block through a groove. The output shaft of the second motor is connected to the power rod through a coupling, and one end of the power rod is installed on the filter frame.

[0007] Optionally, it also includes a bracket, a rotating rod, a first motor, and a stirring rod. The bracket is installed on the top of the machine body, the first motor is installed on the bracket, the output shaft of the first motor is connected to the rotating rod through a coupling, and the stirring rod is installed on the rotating rod.

[0008] Optionally, it also includes a placement rack and a collection box, with the placement rack mounted on the support frame and the collection box movably mounted on the placement rack.

[0009] Optionally, it also includes a dust cover and a fan, with dust covers and fans installed on both sides of the unit, and the air outlet of the fan facing the inside of the dust cover.

[0010] Optionally, the filter frame is vortex-shaped, with the hole at the bottom center of the filter frame being larger than the surrounding holes.

[0011] Optionally, the screen is installed at an angle at the feed inlet.

[0012] The beneficial effects of this invention are: by stirring the sand on the screen while it is being preliminarily screened quickly, the second motor works to drive the filter frame to rotate. Small sand particles are screened out from the smaller holes at the bottom of the filter frame and fall down the inclined surface at the bottom of the machine to the discharge port. Larger particles move to the hole in the center of the filter frame as the filter frame rotates and fall into the collection frame. This achieves efficient and rapid screening and reduces the workload of workers. Attached Figure Description

Detailed Implementation

[0018] The embodiments of this utility model will be described below with reference to the accompanying drawings.

[0019] Example: A sand separator for aggregate production, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the machine includes a support frame 1, a machine body 2, a screen 201, a feed inlet 3, a discharge outlet 8, a placement rack 9, a collection frame 10, a filter frame 13, a buffer block 14, a second motor 15, and a power rod 16. The machine body 2 is mounted on all four support frames 1. A feed inlet 3 is located at the top of the machine body 2, and a screen 201 is installed inside the feed inlet 3. The screen 201 is installed at an angle inside the feed inlet 3 to facilitate rapid screening and filtering of sand. A placement rack 9 is mounted on all four support frames 1, and a collection frame 10 is movably mounted on the placement rack 9. A discharge outlet 8 is located at the bottom of the machine body 2, and the top of the discharge outlet 8 is adjacent to a conical ring at the bottom of the machine body 2 to facilitate... Sand flows along a conical ring towards the discharge port 8, and then flows down the slope of the discharge port 8 to the ground. A filter frame 13 is installed inside the machine body 2. The filter frame 13 is vortex-shaped. The hole at the bottom center of the filter frame 13 is larger than the surrounding holes. The hole at the bottom center of the filter frame 13 is connected to a pipe. Large particles screened out fall into the collection frame 10 along the pipe. A buffer block 14 is installed on the filter frame 13. A second motor 15 is installed in the buffer block 14 through a groove. The output shaft of the second motor 15 is connected to a power rod 16 through a coupling. The bottom of the power rod 16 is a cross-shaped connecting block. One end of the connecting block of the power rod 16 is installed on the filter frame 13.

[0020] like Figure 1 and Figure 2 As shown, it also includes a bracket 4, a rotating rod 5, a first motor 6, a stirring rod 7, a dustproof frame 11, and a fan 12. The bracket 4 is installed on the top of the machine body 2, and the first motor 6 is installed on the bracket 4. The output shaft of the first motor 6 is connected to the rotating rod 5 through a coupling. The stirring rod 7 is installed on the rotating rod 5. Fans 12 are installed on the left and right sides of the machine body 2. The air outlet of the fan 12 faces the inside of the dustproof frame 11. The outer wall of the dustproof frame 11 has ventilation holes. When the fan 12 is screening sand, the dust generated in the air is sucked out from the fan 12 into the dustproof frame 11.

[0021] When the sand separator is powered on, the operator pours sand into the feed inlet 3. The first motor 6 starts working, driving the rotating rod 5 to rotate. At this time, the stirring rod 7 on the rotating rod 5 rotates and stirs the sand. The sand is quickly and initially screened through the inclined screen 201, and larger stones are filtered onto the screen 201. After the initial screening, the sand flows into the outer ring of the filter frame 13 through the inverted funnel-shaped buffer block 14. The second motor 15 starts working, and the power rod 16 drives the filter frame 13 to rotate. Since the filter holes on the outer periphery of the filter frame 13 are smaller and the holes in the center are larger, as the filter frame 13 rotates, small sand particles are screened out from the smaller holes and fall down the inclined surface at the bottom of the machine body 2 to the discharge port 8. Larger particles move to the hole in the center of the filter frame 13 and fall into the collection frame 10 as the filter frame 13 rotates.

[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
