Description

Technical Field

[0001] This utility model relates to the field of screening equipment technology, and in particular to a hexagonal screening device. Background Technology

[0002] A hexagonal screening device is a mechanical device that uses a specially shaped screen to screen materials. It is named for its hexagonal shape. Its main function is to separate materials of different particle sizes. During operation, the material enters the equipment through the feed inlet and is subjected to vibration and gravity on the screen. Smaller particles fall through the screen's openings, while larger particles continue to move along the screen and are eventually discharged from different outlets. Hexagonal screening devices have advantages such as high screening efficiency, large processing capacity, and stable structure, and are widely used in material screening and grading operations in industries such as mining, building materials, and chemicals.

[0003] Existing technologies, such as the utility model patent with publication number CN215198207U, disclose a hexagonal screening machine. A first support block and a second support block are slidably disposed within a first groove of the outer shell of the support assembly. A first heating resistor is disposed within the first groove. The support rod and drive motor of the screening assembly are respectively connected to the first and second support blocks. The hexagonal screen is connected to the drive motor, and the feed plate is connected to the hexagonal screen. Fine materials can be discharged through the fine material outlet under gravity, while coarse materials are discharged from the coarse material outlet. The coarse material is heated by the first heating resistor to remove moisture. The sand enters the hexagonal screen through the open feed plate. The drive motor drives the hexagonal screen to rotate, separating the sand. This method can easily separate sand containing moisture. To prevent the hexagonal screen from clogging, the first and second support blocks can be shaken up and down to vibrate the sand and prevent blockage.

[0004] The existing hexagonal screening machine only performs screening operations by rotating the screen and coordinating with equipment vibration. However, when materials are added to the screen, they are prone to accumulation due to centrifugal force, which affects the screening efficiency of the equipment and is not conducive to its normal use. This needs to be improved. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing hexagonal screening machines, which rely solely on rotating the screen and vibrating the equipment for screening. However, the material added to the screen is prone to accumulation due to centrifugal force, affecting the screening efficiency and hindering normal operation. Therefore, this invention proposes a hexagonal screening device.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a hexagonal screening device, comprising a machine body and a hexagonal screen cylinder. A support is fixedly connected to the lower surface of the machine body. The hexagonal screen cylinder is placed inside the machine body, and transmission discs are fixedly connected to both ends of the hexagonal screen cylinder. A drive wheel is installed on the inner wall of the machine body, and the transmission discs are connected to the drive wheel. A discharge port is fixedly connected to the lower surface of the machine body. A processing device is provided on the surface of the machine body. The processing device includes a baffle block, which is placed inside the hexagonal screen cylinder. A transmission rod is fixedly connected to one side of the baffle block. A fixing plate is fixedly connected to the surface of the machine body. The end of the transmission rod away from the baffle block is rotatably connected to the inner wall of the fixing plate. A baffle is fixedly connected to the surface of the baffle block. An auxiliary device is provided on the surface of the discharge port. This solution has an ingenious structure, which diverts the power source of the equipment and turns the material during screening. At the same time, it extends the time the material spends in the hexagonal screen cylinder, ensuring that the material is fully screened, improving the screening efficiency of the equipment, reducing the workload of the user, and facilitating the normal use of the equipment.

[0007] Preferably, the baffle is inclined, and there are multiple baffles arranged in a circular pattern to facilitate normal use of the equipment.

[0008] Preferably, a mounting frame is fixedly connected to the surface of the machine body, and a transmission wheel is rotatably connected to one side of the mounting frame. The transmission wheel is connected to the surface of the transmission disc, and a control wheel is fixedly connected to one end of the transmission rod. Belts are installed on the transmission wheel and the control wheel, and the transmission wheel is connected to the control wheel via the belts. During processing, the material is added to the hexagonal screen cylinder. The drive wheel drives the transmission disc and the hexagonal screen cylinder to rotate. The transmission disc drives the control wheel, transmission rod, baffle block, and baffle to rotate in the opposite direction via the transmission wheel and belt. When the material in the hexagonal screen cylinder is turned over and falls onto the baffle block and baffle, the baffle pushes some of the material towards the inlet of the hexagonal screen cylinder. Most of the material that meets the specifications falls into the discharge port through the screen holes on the hexagonal screen cylinder.

[0009] Preferably, the inner wall of the machine body is fixedly connected to two symmetrically arranged partitions, and the transmission disc rests on the partitions to prevent material from leaking out from the edges.

[0010] Preferably, the baffle block is a combination of a cone and a cylinder, with the cone end facing the feed inlet of the hexagonal screen cylinder, which facilitates the dispersion of materials and avoids material accumulation.

[0011] Preferably, the auxiliary device includes a scraper, which is placed in the feed inlet. A connecting rod is fixedly connected to the lower surface of the scraper, and a pull ring is fixedly connected to the end of the connecting rod away from the scraper. After the material processing and screening operation is completed, pulling the pull ring back and forth will drive the scraper to move through the connecting rod, and the scraper will scrape off the material attached to the inner wall of the feed inlet.

[0012] Preferably, a guide sleeve is fixedly connected to the upper surface of the connecting rod, and a positioning rod is fixedly connected to the surface of the discharge port. The guide sleeve slides on the surface of the positioning rod, effectively ensuring stable displacement of the scraper.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In this invention, during processing, the material is added to the hexagonal screen cylinder. A drive wheel rotates the transmission disc and the hexagonal screen cylinder. The transmission disc, via a transmission wheel and belt, drives the control wheel, transmission rod, baffle block, and baffle to rotate in the opposite direction. When the material in the hexagonal screen cylinder is turned over and falls onto the baffle block and baffle, the baffle pushes some of the material closer to the inlet of the hexagonal screen cylinder. Most of the material that meets the specifications falls into the discharge port through the screen holes on the hexagonal screen cylinder. After the material processing and screening operation is completed, pulling the pull ring back and forth moves the scraper rod, which then scrapes off the material adhering to the inner wall of the discharge port. This ingenious design diverts the power source of the equipment and turns the material over during screening, while extending the time the material spends in the hexagonal screen cylinder, ensuring thorough screening, improving the screening efficiency of the equipment, reducing the user's workload, and facilitating normal operation of the equipment.

The transmission discs 5 and the drive wheel 4 are connected in a transmission connection. A discharge port 6 is fixedly connected to the lower surface of the body 1. A processing device 7 is provided on the surface of the body 1. The processing device 7 includes a baffle block 71, which is placed inside the hexagonal screen cylinder 3. One side of the baffle block is fixedly connected to the support 2. A transmission rod 78 is fixedly connected to the surface of the machine body 1, and a fixed plate 77 is fixedly connected to the surface of the machine body 1. The end of the transmission rod 78 away from the baffle block 71 is rotatably connected to the inner wall of the fixed plate 77. A baffle 72 is fixedly connected to the surface of the baffle block 71, and an auxiliary device 8 is provided on the surface of the discharge port 6. This solution has an ingenious structure, which diverts the power source of the equipment and turns it over during material screening. At the same time, it extends the time that the material spends in the hexagonal screen cylinder 3, ensuring that the material is fully screened, improving the screening efficiency of the equipment, reducing the workload of the user, and facilitating the normal use of the equipment.

[0024] Specifically, the baffle 72 is inclined, and there are multiple baffles 72 arranged in a circle to facilitate the normal use of the equipment.

[0025] In this embodiment: A mounting frame 73 is fixedly connected to the surface of the machine body 1. A transmission wheel 74 is rotatably connected to one side of the mounting frame 73. The transmission wheel 74 is connected to the surface of the transmission disc 5. A control wheel 76 is fixedly connected to one end of the transmission rod 78. A belt 75 is installed on the transmission wheel 74 and the control wheel 76. The transmission wheel 74 is connected to the control wheel 76 through the belt 75. During processing, the material is added into the hexagonal screen cylinder 3. The drive wheel 4 drives the transmission disc 5 and the hexagonal screen cylinder 3 to rotate. The transmission disc 5 drives the control wheel 76, the transmission rod 78, the baffle block 71 and the baffle plate 72 to rotate in the opposite direction through the transmission wheel 74 and the belt 75. When the material in the hexagonal screen cylinder 3 is turned over and falls onto the baffle block 71 and the baffle plate 72, the baffle plate 72 pushes some of the material towards the inlet of the hexagonal screen cylinder 3. Most of the material that meets the specifications falls into the discharge port 6 through the screen holes on the hexagonal screen cylinder 3.

[0026] Specifically, the inner wall of the machine body 1 is fixedly connected to two symmetrically arranged partitions 9, and the transmission disc 5 rests on the partitions 9 to prevent material from leaking out from the edges.

[0027] Specifically, the baffle block 71 is a combination of a cone and a cylinder, with the cone end facing the feed inlet of the hexagonal screen cylinder 3, which facilitates the dispersion of materials and avoids material accumulation.

[0028] In this embodiment: the auxiliary device 8 includes a scraper 81, which is placed in the feed port 6. A connecting rod 84 is fixedly connected to the lower surface of the scraper 81. A pull ring 85 is fixedly connected to the end of the connecting rod 84 away from the scraper 81. After the material processing and screening operation is completed, the pull ring 85 is pulled back and forth, which can drive the scraper 81 to move through the connecting rod 84. The scraper 81 then scrapes off the material attached to the inner wall of the feed port 6.

[0029] Specifically, a guide sleeve 83 is fixedly connected to the upper surface of the connecting rod 84, and a positioning rod 82 is fixedly connected to the surface of the discharge port 6. The guide sleeve 83 slides on the surface of the positioning rod 82, effectively ensuring the stable displacement of the scraper rod 81.

[0030] Working principle: During processing, the material is added to the hexagonal screen cylinder 3. The drive wheel 4 drives the transmission disc 5 and the hexagonal screen cylinder 3 to rotate. The transmission disc 5 drives the control wheel 76, transmission rod 78, baffle block 71, and baffle plate 72 to rotate in the opposite direction via the transmission wheel 74 and belt 75. When the material in the hexagonal screen cylinder 3 is turned over, it falls onto the baffle block 71 and baffle plate 72. The baffle plate 72 pushes some of the material closer to the inlet of the hexagonal screen cylinder 3. Most of the material that meets the specifications falls into the discharge port 6 through the screen holes on the hexagonal screen cylinder 3. After the material processing and screening operation is completed, pulling the pull ring 85 back and forth will drive the scraper 8 through the connecting rod 84. 1. Displacement: The scraper 81 then scrapes off the material adhering to the inner wall of the discharge port 6. This ingenious design diverts the power source of the equipment and agitates the material during screening, while extending the time the material spends in the hexagonal screen cylinder 3. This ensures thorough screening, improves the screening efficiency of the equipment, reduces the workload of the user, and facilitates the normal use of the equipment.
