Description

Technical Field

[0001] The utility model relates to the field of stone classification equipment, in particular to an automatic stone classification device used in mining. Background Art

[0002] Rocks or rock-like materials used as materials for construction, sculpture, etc. Stone refers to all stones that can be used as materials, such as granite, shale, mudstone, etc. Stone piles, masonry, and slag are also stones.

[0003] characteristic

[0004] Roads and bridges in stone production lines are subject to the complex force system of vehicle loads and the adverse effects of various complex natural factors. Therefore, the materials used for construction and bridges must not only have certain mechanical properties, but also have durability without significant strength loss under the influence of adverse natural factors. This requires that road materials should have the following properties:

[0005] Commonly used stones

[0006] 1. Stone products for road pavement construction: regular blocks for high-grade paving, semi-regular blocks for road pavement, irregular blocks for paving, and tapered blocks.

[0007] 2. Main stone products used in bridge construction: slabs, blocks, square stones, rough stones, facing stones, etc.

[0008] 3. Rockfill, masonry and slag that may be used in the construction of earth-rock dams. [2]

[0009] 4. Other materials used in architectural sculptures, such as stone carving, sandstone sculpture quarrying art, cultural stone, sand products, etc., can be collectively referred to as stone. Sculpture mainly involves artificial carving, modification, and even coloring of larger pieces of stone.

[0010] In the current social environment, there are more and more beautiful buildings. Different styles of buildings require different types of stones, and the same stones of different sizes are also used in different scenarios. Therefore, it is necessary to classify and collect the sizes of stones so that they can be directly used in different places. However, when classifying stones, the operation of the equipment is often accompanied by a lot of dust flying. Therefore, it is very meaningful to design a stone classification equipment that can solve the above problems. Utility Model Content

[0021] When the stone in the feed hopper passes through the guide plate and falls on the first rolling rods, the drive motor is started, and the rotating shaft of the drive motor drives the first rotating rod to rotate. When the first rotating rod rotates, it drives the first rolling rods to rotate together through the transmission belt, so that the stone falling on the first rolling rod can roll to the discharge port, and then enter the containing box to be collected after being guided by the first unloading plate. The distance between the first rolling rods can make the stone smaller than these distances fall on the secondary classification component, and then complete the secondary classification. The function of classifying stones of different sizes is realized.

[0022] Further, the secondary classification component includes: a second rotating rod, a plurality of second rolling rods, a second blanking plate, a chain, and two sprockets. The second rotating rod is arranged between the two baffles and below the first rotating rod. The two ends of the second rotating rod respectively penetrate the two baffles and extend to the outside of the two baffles and are rotatably connected with the two baffles. The rotation axis is perpendicular to the front of the first shell. The two sprockets are respectively sleeved on the ends of the rotating shaft of the first rotating rod and the second rotating rod close to the driving motor and are located on the side of the baffle. The two sprockets are respectively fixedly connected to the side of the first rotating rod and the side of the second rotating rod. The chain is sleeved on the two sprockets.

The second blanking plate is obliquely arranged on the side of the first shell, arranged in the discharge port, and located below a plurality of second rolling rods. The side surface of the second blanking plate is fixedly connected to the side wall of the discharge port.

[0023] When the stone falls on several second rolling rods, the rotation of the first rotating rod will drive one of the sprockets to rotate together, and the rotation of one of the sprockets will drive another sprocket to rotate through the chain, and the rotation of the other sprocket will drive the second rotating rod to rotate together, and the rotation of the second rotating rod will drive several second rolling rods to rotate together through the transmission belt, and the rotation of the second rolling rod will drive the stone to move, so that the qualified stone leaves the first shell through the discharge port, and then passes through the second unloading plate into the containing box. The unqualified stone falls into the waste collection device through the distance between several second rolling rods, completing the function of secondary classification and collection of the stone.

[0024] Furthermore, the waste collection device includes: a waste box and a plurality of slide rails.

[0026] Furthermore, the fan blade protection device includes: an inclined plate and a filter. The inclined plate is arranged inside the connecting pipe, and the side wall of the inclined plate is fixedly connected to the inner wall of the connecting pipe. The filter is arranged inside the connecting pipe and between the exhaust fan and the inclined plate, and the filter is fixedly connected to the inner wall of the connecting pipe.

[0027] When the exhaust fan is started, the rotation of the fan blades will drive the airflow of the first shell into the connecting pipe and into the second shell. When the airflow flows, the airflow will drive some small stones into the connecting pipe. At this time, the small stones hit the filter with the airflow, are blocked by the filter, and then fall on the inclined plate and roll back into the first shell. The small stones entering the connecting pipe will not be sucked in by the fan blades of the exhaust fan, thus avoiding hitting the fan blades and reducing the service life of the exhaust fan.

[0028] Furthermore, it also includes: a sprinkler and a sewage outlet. The sprinkler is arranged inside the second shell and fixedly connected to the top surface of the second shell. The input port of the sprinkler is connected to the water supply pipe through a water pipe, and the sprinkler is electrically connected to the controller. The sewage outlet is arranged at the bottom of the second shell, the sewage outlet is connected to the inside of the second shell, and the sewage outlet is connected to the sewer through a water pipe.

[0029] When the controller starts the exhaust fan, the controller will also control the sprinkler to start, and the sprinkler will spray water into the second shell. The water droplets will absorb the flying dust in the second shell, and then fall on the bottom surface of the second shell until it enters the sewage outlet, and then flows into the sewer through the sewage outlet through the water pipe, so as to assist the dust cleaning function.

[0030] Beneficial effects of the utility model:

[0031] 1. Through the mutual cooperation and support between the first shell, the stone classification device, the exhaust dust removal device, and the controller, when the stone enters the feed hopper, it falls on the guide plate through the feed port. The guide plate can make the stone fall accurately on the multi-layer classification device, and at the same time, it can assist the exhaust fan to efficiently absorb the dust generated when the stone rolls on the guide plate. At the same time, the multi-layer classification device can also classify the stones into different sizes at the same time, thereby improving the classification efficiency. The stones are classified and collected into the storage box, and the storage box applies pressure to the spring through the second horizontal plate. The spring shortens until the second horizontal plate can press the control button, and then the exhaust fan is controlled to start through the controller, thereby realizing the function of automatically controlling the start of the exhaust fan through the increase of gravity. With such a functional setting, the technical effect of allowing the equipment to classify and collect stones while the equipment can automatically handle the flying dust inside it is achieved.

The waste box 401 passes through the side surface of the first housing 1, and the bottom surface is slidably connected to the plurality of slide rails 402.

[0051] When the stones pass through the gaps between the second rolling rods 311 and enter the waste box 401, if the waste box 401 is full, the user can pull the waste box 401 out of the first shell 1, and the waste box 401 will leave the first shell 1 along the sliding direction of the slide rail 402, and then wait for the user to collect the waste. After the collection is completed, the user pushes the waste box 401 into the first shell 1 through the slide rail 402 to complete the function of collecting and processing the waste.

[0052] The fan blade protection device includes: an inclined plate 501 and a filter 502. The inclined plate 501 is arranged inside the connecting pipe 201, and the side wall of the inclined plate 501 is fixedly connected to the inner wall of the connecting pipe 201. The filter 502 is arranged inside the connecting pipe 201 and between the exhaust fan 202 and the inclined plate 501, and the filter 502 is fixedly connected to the inner wall of the connecting pipe 201.

[0053] When the exhaust fan 202 is started, the rotation of the fan blades will drive the airflow of the first shell 1 through the connecting pipe 201 into the second shell 203. When the airflow flows, the airflow will drive some small stones into the connecting pipe 201. At this time, the small stones hit the filter 502 with the airflow, are blocked by the filter 502, and then fall on the inclined plate 501, and then roll back into the first shell 1, so that the small stones entering the connecting pipe 201 will not be sucked in by the fan blades of the exhaust fan 202, thereby avoiding hitting the fan blades of the exhaust fan 202 and reducing the service life of the exhaust fan 202.

[0054] It also includes: a sprinkler 6 and a sewage outlet 7. The sprinkler 6 is arranged inside the second housing 203 and fixedly connected to the top surface of the second housing 203. The input port of the sprinkler 6 is connected to the water supply pipe through a water pipe, and the sprinkler 6 is electrically connected to the controller. The sewage outlet 7 is arranged at the bottom of the second housing 203, the sewage outlet 7 is connected to the inside of the second housing 203, and the sewage outlet 7 is connected to the sewer through a water pipe.

[0055] When the controller starts the exhaust fan 202, the controller will also control the sprinkler 6 to start together. The sprinkler 6 will spray water into the second shell 203. The water droplets will absorb the flying dust in the second shell 203, and then fall on the bottom surface of the second shell 203 until it enters the sewage outlet 7, and then flows into the sewer through the sewage outlet 7 through the water pipe, so as to assist the dust cleaning function.

[0056] Working principle:

[0057] When the user puts the stone into the feed hopper 101, the stone will pass through the feed port 102 and fall onto the guide plate 103. The guide plate 103 can guide the stone to accurately roll onto several first rolling rods. At the same time, the user starts the drive motor through the controller. After the drive motor is started, it will drive the first rotating rod 308 to rotate. When the first rotating rod 308 rotates, it will drive several first rolling rods to rotate together through the transmission belt, so that the stone falling above the first rolling rod can roll to the discharge port 104, and then be guided by the first unloading plate 309 into the containing box 303 to be collected. The distance between the first rolling rods can make the stones smaller than the distance fall onto the second rolling rods 311. At the same time, the first rotating rod 308 rotates to drive one of the sprockets 313 to rotate together. When one of the sprockets 313 rotates, it drives another sprocket 313 to rotate through the chain. When the other sprocket 313 rotates, it drives the second rotating rod 310 to rotate together. When the second rotating rod 310 rotates, it drives the second rolling rods 311 to rotate together through the transmission belt. When the second rolling rod 311 rotates, it drives the stones to move, so that qualified stones leave the first housing 1 through the discharge port 104, and then enter the containing box 303 through the second unloading plate 312. Unqualified stones fall into the waste box 401 through the distance between the second rolling rods 311 and are collected.

[0058] At the same time, when there are stones in the receiving box 303, the receiving box 303 will apply gravity to the second horizontal plate 302, so that the second horizontal plate 302 can press down the spring 304, until the application of gravity causes the spring 304 to shorten to a certain extent, so that the second horizontal plate 302 can press the control button 305. When the control button 305 is pressed, a control signal will be sent to the controller, and the controller will control the exhaust fan 202 to start after receiving the signal. When the exhaust fan 202 is started, the dust scattered by the stones in the first housing 1 will be sucked into the second housing 203 through the connecting pipe 201, and then discharged from the second housing 203 at the air outlet 204 after being filtered by the filter. The connecting pipe 201 is arranged above the guide plate 103, which can effectively suck in the dust generated when the stones on the guide plate 103 roll down, thereby improving the efficiency of dust collection. When the controller starts the exhaust fan 202, the controller will also control the sprinkler 6 to start together. The sprinkler 6 will spray water into the second shell 203. The water droplets will absorb the flying dust in the second shell 203, and then fall on the bottom surface of the second shell 203 until it enters the sewage outlet 7, and then flows into the sewer through the sewage outlet 7 through the water pipe, so as to assist the dust cleaning function.

[0059] When the exhaust fan 202 is started, the rotation of the fan blades will drive the airflow of the first shell 1 to enter the second shell 203 through the connecting pipe 201. When the airflow flows, the airflow will drive some small stones into the connecting pipe 201. At this time, the small stones hit the filter 502 with the airflow, are blocked by the filter 502, and then fall on the inclined plate 501, and then roll back into the first shell 1, so that the small stones entering the connecting pipe 201 will not be sucked in by the fan blades of the exhaust fan 202, thereby avoiding hitting the fan blades of the exhaust fan 202 and reducing the service life of the exhaust fan 202.

[0060] When the waste box 401 is full, the user can pull the waste box 401 out of the first shell 1, and the waste box 401 will leave the first shell 1 along the sliding direction of the slide rail 402, and then wait for the user to collect the waste. After the collection is completed, the user pushes the waste box 401 into the first shell 1 through the slide rail 402 to complete the collection and processing of the waste. The above embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model.
