Description

Technical Field

[0001] The invention relates to the technical field of soil screening devices, in particular to a soil screening device for producing high-voltage porcelain insulators. Background Art

[0002] The soil screening device used in the production of high-voltage porcelain insulators is used to screen and grade soil particles to ensure that the quality of the final porcelain insulators meets the standards. High-voltage porcelain insulators have high requirements for soil, so the screening process is crucial to ensuring the quality of insulators.

[0003] According to a disclosed soil screening device for porcelain insulator production (Announcement No.: CN115365125A), in the above application, if the cloth plate in the first step of screening is blocked by stones in the soil, it is necessary to pull out the cloth plate for cleaning. At this time, the screening equipment must be stopped for screening, which affects the screening efficiency. After the crushing roller crushes the soil, if there are stones or other hard impurities in the soil block, they will still be discharged together, and it is impossible to ensure that the impurities or stones wrapped in the soil block are effectively screened. The soil blocks that cannot pass through the screening net cannot be effectively utilized at all. It is impossible to first screen the soil and the stones or impurities wrapped in the soil, and then further screen the loose soil. The screening efficiency is very limited. Moreover, the static screening net is easy to cause the screening net to be blocked when screening the soil due to the certain adhesion of the soil, thereby further reducing the screening efficiency.

The rotating shaft 23 passes through and is fixedly connected with the bevel gear 1 31, the bevel gear 1 31 is meshed with the bevel gear 2 33, the inner side of the bevel gear 2 33 passes through and is fixedly connected with the connecting rod 1 32, and the end of the connecting rod 1 32 away from the bevel gear 2 33 is fixedly connected with the universal joint 35. One end of the universal joint 35 away from the connecting rod 1 32 is fixedly connected to the connecting rod 2 36, and a buckle 34 is fixedly connected to the side of the body 1. A reciprocating screw 37 passes through the inner side of the buckle 34, and the universal joint 35 is also fixedly connected between the reciprocating screw 37 and the connecting rod 2 36. Since the rotating shaft 23 passes through and is fixedly connected with the bevel gear 1 31, the bevel gear 1 31 drives the connecting rod 1 32 to rotate through the bevel gear 2 33, and at the same time, the connecting rod 1 32 will drive the reciprocating screw 37 to rotate through the connecting rod 2 36 with the universal joint 35 fixedly connected at both ends. The connecting rod 1 32 and the connecting rod 2 36 are also penetrated and rotatably connected with a buckle 34, the reciprocating screw rod 37 is penetrated and threadedly connected with a screw sleeve 38, the surface of the screw sleeve 38 is fixedly connected with a slide rod 39, and a slide groove 314 is opened on the side of the body 1, the screw sleeve 38 is penetrated and threaded by the reciprocating screw rod 37, and at the same time, the slide rod 39 on the surface of the screw sleeve 38 penetrates the slide groove 314, so that the slide groove 314 limits the slide rod 39, and then when the reciprocating screw rod 37 rotates, the slide rod 39 is driven by the screw sleeve 38 to slide back and forth in the slide groove 314, and the slide rod 39 penetrates the slide groove 314 and is slidably connected. One end of the slide bar 39 located on the inner side of the machine body 1 is fixedly connected to a linkage block 310, and a rotating rod 311 penetrates the inner side of the linkage block 310. Since the rotating shaft 23 penetrates and is fixedly connected to the bevel gear 1 31, the bevel gear 1 31 drives the connecting rod 1 32 to rotate through the bevel gear 2 33. At the same time, the connecting rod 1 32 drives the reciprocating screw rod 37 to rotate through the connecting rod 2 36 with universal joints 35 fixedly connected at both ends. The end of the rotating rod 311 located on the inner side of the machine body 1 penetrates and is fixedly connected to a brush roller 312. A second screen 313 is fixedly connected to the inner side of the body 1. When the reciprocating screw 37 rotates, the slide rod 39 is driven to slide back and forth in the slide groove 314 through the screw sleeve 38, and the slide rod 39 will drive the rotating rod 311 located on the inner side of the linkage block 310 to move together through the linkage block 310, so that the rotating rod 311 drives the brush roller 312 that penetrates and is fixedly connected to reciprocate together, and the brush roller 312 will scrape the soil on the second screen 313, thereby improving the screening efficiency of the second screen 313 for soil.A wave groove 315 is provided on the inner side of the body 1. When the linkage block 310 reciprocates due to the sliding rod 39, the rotating rod 311 is inserted into the linkage block 310 and the wave groove 315 at the same time. Therefore, the rotating rod 311 reciprocates up and down in the linkage block 310 under the resistance of the wave groove 315 while following the linkage block 310 to move back and forth. When the rotating rod 311 reciprocates up and down, the gear 2 318 penetrated by and fixedly connected to the rotating rod 311 will reciprocate while meshing with the rack 317. The end of the rotating rod 311 away from the brush roller 312 is inserted into the inner side of the wave groove 315. A rack 317 is fixedly connected to the surface of the linkage block 310. When the rotating rod 311 is raised and lowered, the brush roller 312 will also hit the second screen 313 to force the second screen 313 to vibrate. The screening efficiency of the second screen 313 can be further improved when the brush roller 312 rotates itself, and the blockage of the second screen 313 can also be avoided. The rotating rod 311 passes through and is fixedly connected with a gear 2 318, and the gear 2 318 is meshed with the rack 317. A slide plate 319 passes through and is slidably connected to the inner side of the linkage block 310, and a spring 2 320 is fixedly connected between the slide plate 319 and the inner side of the linkage block 310.

[0032] Based on the above embodiment, when the screening device screens the soil, the soil is first poured into the interior of the machine body 1 through the feed hopper 4, and then the motor 22 is started. The output shaft of the motor 22 drives the rotating shaft 23 to rotate through the synchronous wheel 24 and the synchronous belt 25. When the rotating shaft 23 rotates, the gear 26 is driven to rotate so that the middle rotating shaft 23 and the rotating shafts 23 on the left and right sides can all rotate, and further the crushing roller 27 rotates with the rotating shaft 23. When the middle rotating shaft 23 rotates, the cam 28 is also driven to rotate. When the cam 28 rotates a certain distance, it will contact the first screen 212, so that the first screen 212 drives the L-shaped block 210 located in the active cavity 29 to rise, and the L-shaped block 210 will compress the spring 211. When the cam 28 rotates a certain distance and no longer contacts the first screen 212, the spring 1 211 will push back the L-shaped block 210, and the high-speed rotation of the cam 28 will repeatedly contact the first screen 212 to make the first screen 212 constantly shake, and the loose soil will be shaken and pass through the first screen 212, while the impurities or stones mixed in the soil that cannot pass through can only be discharged through the first discharge port 5 opened on the side, and even the soil blocks in the soil that pass through the first screen 212 will be crushed under the action of the crushing roller 27 driven by the rotating shaft 23, so that only the loose soil can pass and fall onto the second screen 313, avoiding the impurities or stones in the soil from being mixed in the soil and affecting the subsequent production of high-voltage porcelain insulators.

[0033] When the soil falls onto the second screen 313, since the rotating shaft 23 penetrates and is fixedly connected with the bevel gear 1 31, the bevel gear 1 31 drives the connecting rod 1 32 to rotate through the bevel gear 2 33, and the connecting rod 1 32 drives the reciprocating screw 37 to rotate through the connecting rod 2 36 with universal joints 35 fixedly connected at both ends, and the screw sleeve 38 is penetrated by the reciprocating screw 37 and threadedly connected, and the sliding rod 39 on the surface of the screw sleeve 38 penetrates the slide groove 314, so that the slide groove 314 is The slide rod 39 is limited, and then when the reciprocating screw rod 37 rotates, the slide rod 39 is driven by the screw sleeve 38 to slide back and forth in the slide groove 314, and the slide rod 39 will drive the rotating rod 311 located on the inner side of the linkage block 310 to move together through the linkage block 310, so that the rotating rod 311 drives the brush roller 312 that penetrates and is fixedly connected to reciprocate together, and the brush roller 312 will scrape the soil on the second screen 313, thereby improving the screening efficiency of the second screen 313 for soil.

[0034] When the linkage block 310 reciprocates due to the slide bar 39, the rotating rod 311 is inserted into the linkage block 310 and the wave groove 315 at the same time, so that the rotating rod 311 follows the linkage block 310 to reciprocate, and at the same time, it is located in the linkage block 310 to reciprocate up and down under the resistance of the wave groove 315. When the rotating rod 311 reciprocates up and down, the gear 2 318 that the rotating rod 311 penetrates and is fixedly connected will reciprocate while meshing with the rack 317, so that the rotating rod 311 drives the brush roller 312 to reciprocate, so that the brush The cleaning effect of the roller 312 is improved, and at the same time, when the rotating rod 311 is raised and lowered, the brush roller 312 will also hit the second screen 313 to force the second screen 313 to vibrate, and cooperate with the rotation of the brush roller 312 itself to further improve the screening efficiency of the second screen 313, and can also avoid the blockage of the second screen 313. If there are impurities such as stones that cannot pass through the second screen 313, they will vibrate in the second screen 313 and gradually roll along the inclined second screen 313 to the second discharge port 6 for discharge, so that only loose and qualified soil can be discharged through the third discharge port 7.

[0035] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
