Description

Technical Field

[0001] The present application relates to the technical field of transport and screening equipment, and in particular to a screening scraper machine. Background Art

[0002] Scraper conveyors are usually used to transport bulk raw materials such as grains and beans. According to subsequent special process requirements, the scraper conveyor is usually required to transport materials that meet the qualified particle size before they can reach the next stage.

[0003] Since conventional scraper conveyors do not have screening functions, the conveyed materials need to be screened in advance or sent to the next process section for screening. The overall process is relatively complicated. Usually, a screening grid is additionally set in front of the scraper conveyor head discharge port. According to the gap size of the screening grid, the materials that do not meet the particle size requirements are screened in advance. When the transported material is thick, the material close to the screening grid can be screened through the screening grid. The upper material will be conveyed to the next process because there is no time to screen it, and the overall screening effect is not good. Summary of the invention

[0004] In order to improve the efficiency of a screening scraper during use, the present application provides a screening scraper.

[0005] The present application provides a screening scraper machine, which adopts the following technical solution:

[0006] A screening scraper machine comprises a conveyor body, which is connected by a transport box, the conveyor body comprises a head and a tail, the transport box is provided with a discharge port near the head, the transport box is provided with a feed port near the tail, a conveying device for transporting materials is installed in the transport box, a screening outlet is provided on the transport box, a screening component for screening materials is installed near the head of the transport box, the screening component comprises a screening plate, the screening plate is installed on the bottom surface of the transport box, the screening plate is arranged at the screening outlet, more than two screening bars are installed on the screening plate, there is a gap between each of the screening bars and they are arranged equidistantly, and a swing component for moving materials is connected to the transport box.

[0007] By adopting the above technical scheme, the material is put into the bottom of the transport box from the feed port, and the transport device transports the material smoothly from the tail of the machine to the head of the machine. When it is about to reach the head of the machine, the material with qualified particle size is screened out of the transport box by the screening plate of the screening component, and the material with unqualified size is continued to be transported to the discharge port of the head of the machine, and the material with the required particle size is screened out of the transport box in advance, and the material is moved by the swing component to enhance the screening effect, prevent the material from being blocked between the screening bars, reduce the qualified size of the material entering the subsequent processing stage, which is beneficial to saving energy, and at the same time can improve the speed of subsequent processing and crushing of the material, which is beneficial to improving the efficiency of the screening scraper during use.

[0008] In a specific feasible implementation scheme, a carrier plate is installed on the transport box, and the swing assembly is divided into a driving part and an execution part, the driving part includes a first mounting plate, the first mounting plate is installed on the carrier plate, a rotating sleeve is rotatably installed on the first mounting plate, a second motor for controlling the rotation of the rotating sleeve is installed on the first mounting plate, a sliding rod is slidably installed on the rotating sleeve, a first baffle is installed on the sliding rod, a first sliding groove is opened on the rotating sleeve, the first baffle passes through the first sliding groove and is arranged on the outside of the rotating sleeve, a second baffle is installed on the rotating sleeve, and a first spring is sleeved on the rotating sleeve, one end of the first spring is connected to the first baffle, and the other end is connected to the second baffle. The cam is provided with a first stop block for controlling the sliding bar to slide on the rotating sleeve, and a second stop block for controlling the sliding bar to slide on the rotating sleeve is provided on the second support rod, and a pull belt is provided on the rotating wheel, and the pull belt is connected to the execution part.

[0009] By adopting the above technical solution, the second motor controls the rotation of the rotating sleeve and the sliding rod, and the sliding rod drives the lever to rotate. When the lever rotates to abut against the first stop block, the lever pushes the rotating wheel to rotate, which is convenient for the rotating wheel to pull the drawstring to be wound on the rotating wheel, and the action of the execution part is controlled. When the lever rotates to the first stop block, the first beveled surface on the first stop block pushes the slide rod to slide in the rotating sleeve, so that the lever is separated from the first stop block. After the lever is separated from the first stop block, the lever loses its resistance to the first stop block, which is convenient for the drawstring to pull the rotating wheel to rotate. When the lever returns to its original position, after the lever rotates and leaves the first stop block, the first spring pushes the first stop plate, and the first stop plate drives the sliding rod to slide in the rotating sleeve to make the lever close to the rotating wheel. The rotating sleeve rotates and drives the lever to rotate toward the second stop block, so that the lever can quickly return to its original position and prepare to push the second stop block to control the movement of the actuator again next time. The lever pushes the first stop block and the second stop block alternately on the rotating wheel to drive the rotating wheel to rotate. The lever is controlled by the first stop block and the second stop block to control the return of the rotating wheel, which is convenient for repeatedly controlling the actuator to move the material.

[0010] In a specific feasible implementation scheme, the execution part includes a fixed rod, which is mounted on the carrier plate, and the fixed rod is arranged below the screening plate. A loading block is mounted on the fixed rod, and a second slide groove is provided on the loading block. The loading block 428 is slidably connected to a slider through the second slide groove. A first guide rod is mounted on the loading block, and a first connecting groove is provided on the slider. The first guide rod extends into the second connecting groove and is slidably connected to the slider. A second spring is sleeved on the first guide rod, and one end of the second spring is connected to the slider and the other end is connected to the loading block. The slider is connected to a first connecting rod, and the first connecting rod is connected to a fixed block. A top block for moving materials is mounted on the fixed block, and the top block is arranged between the screening bars.

[0011] By adopting the above technical solution, when the rotating wheel pulls the drawstring to reel on the rotating wheel, the drawstring pulls the slider to slide on the loading block, the slider compresses the second spring, and the slider drives the top block to slide between the gaps of the screening bars. The top block moves the material in the gaps of the screening bars, and the material is stirred to facilitate the exchange of material positions on the screening plate, so that the thicker material can be rolled close to the screening plate, thereby enhancing the screening effect. When the lever is separated from the first block, the second spring pushes the slider to slide back on the loading block, and the slider drives the top block to flip the material on the return path. The slider pulls the drawstring so that the drawstring drives the rotating wheel to rotate back, so that the thicker layer of material can be flipped close to the screening plate for sorting, thereby enhancing the screening effect of the material, and is conducive to improving the efficiency of the screening scraper during use.

[0012] In a specific feasible implementation scheme, an adjustment component for adjusting the height of the first connecting rod is installed on the slider, and the adjustment component includes a screw rod, which is threadedly connected to the slider, and a mounting groove is opened on the slider, one end of the screw rod extends into the mounting groove, and the end of the screw rod extended into the mounting groove is rotatably connected to a push plate, a push block is slidably installed on the slider, one end of the push block extends into the mounting groove and abuts against the push plate, and one end of the push block extended into the mounting groove is connected to a third spring, and the third spring is connected to the slider at one end away from the push block.

[0013] In a specific implementation scheme, the push block extends into the installation slot at one end and is provided with a third bevel surface, the push plate is provided with a fourth bevel surface near the push block at one end, and the push plate and the push block abut against each other at the positions of the third bevel surface and the fourth bevel surface.

[0014] By adopting the above technical solution, the push plate can quickly push the push block to rise by means of the beveled surface, so that the height of the push block can be quickly adjusted.

[0015] In a specific feasible implementation scheme, a third sliding groove is provided on the fixed block, and the top block is slidably connected to the fixed block via the third sliding groove, a second guide rod is installed on the fixed block, and the second guide rod is arranged in the third sliding groove, a second connecting groove is provided on the top block, and the top block is slidably connected to the second guide rod via the second connecting groove, a fourth spring is sleeved on the second guide rod, one end of the fourth spring is connected to the top block, and the other end is connected to the fixed block.

[0016] By adopting the above technical solution, when the top block encounters the scraper for transporting materials, the top block is used as an elastic member so that the scraper can press the top block back into the fixed block, and the top block can be actively lifted through the fourth spring, so that the top block can self-adjust when encountering the scraper so that the scraper can smoothly transport materials.

[0017] In a specific implementation scheme, the top block is configured to be in an A shape at one end away from the fixing block.

[0018] By adopting the above technical solution, the top block can be quickly pressed back into the fixed block through the A-shaped inclined surface on the top block.

[0019] In a specific possible implementation manner, the screening bar is configured to be V-shaped at one end close to the screening outlet.

[0020] By adopting the above technical solution, the screening bar is set to be V-shaped near the screening outlet, and the gap between the screening bars near the screening outlet is increased, so that the material can fall quickly between the screening bars after screening.

[0021] In a specific feasible implementation scheme, the transport device includes a transmission main wheel, which is rotatably mounted on the transport box near the front of the aircraft, and a first motor for controlling the rotation of the transmission main wheel is installed on the transport box. A transmission secondary wheel is rotatably mounted in the transport box near the tail of the aircraft, and the transmission main wheel and the transmission secondary wheel are connected by a transmission chain.

[0022] By adopting the above technical solution, when the material is put onto the carrier, the first motor controls the transmission main wheel to rotate, and the transmission main wheel controls the movement of the transmission chain to make the scraper push the material on the transport box from the tail to the front of the machine. By pushing the material to move, the material can be gradually dispersed on the bottom plate of the transport box during transportation, which is convenient for screening the material when approaching the front of the machine, thereby enhancing the screening effect of the material.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. Put the material into the bottom of the transport box from the feed port, and the conveying device will transport the material smoothly from the tail of the machine to the head of the machine. When it is about to reach the head of the machine, the screening plate of the screening component will screen the material with qualified particle size out of the transport box, and the material with unqualified size will continue to be transported to the discharge port of the head of the machine, and the material with the required particle size will be screened out of the transport box in advance, and the swing component will be used to move the material to enhance the screening effect, prevent the material from being blocked between the screening bars, reduce the qualified size of the material entering the subsequent processing stage, which is beneficial to saving energy, and at the same time can increase the speed of subsequent processing and crushing of the material, which is beneficial to improve the efficiency of the screening scraper during use.

[0025] 2. Through the setting of the swing assembly, the second motor controls the rotation of the rotating sleeve and the sliding rod, and the sliding rod drives the lever to rotate. When the lever rotates to abut against the first stop block, the lever pushes the rotating wheel to rotate, so that the rotating wheel pulls the drawstring to be wound on the rotating wheel, and the action of the actuator is controlled. When the lever rotates to the first stop block, the first beveled surface on the first stop block pushes the sliding rod to slide in the rotating sleeve, so that the lever is separated from the first stop block. After the lever is separated from the first stop block, the lever loses its resistance to the first stop block, so that the drawstring pulls the rotating wheel to rotate. When the lever is turned back to its original position, and the lever rotates to leave the first stop block, the first spring pushes the first stop plate, and the first stop plate drives the sliding rod to slide in the rotating sleeve to make the lever close to the rotating wheel. The rotating sleeve rotates and drives the lever to rotate toward the second stop block, so that the lever can quickly return to its original position and prepare to push the second stop block next time to control the movement of the actuator again. The lever pushes the first stop block and the second stop block alternately on the rotating wheel to drive the rotating wheel to rotate. The lever is controlled by the first stop block and the second stop block to control the return of the rotating wheel, which is convenient for repeatedly controlling the actuator to move the material.

DETAILED DESCRIPTION

[0038] The following is combined with Figure 1-11 This application is described in further detail. Example

[0039] The present application embodiment discloses a screening scraper machine, referring to Figure 1 and Figure 2 , including a conveyor body 1, which is composed of several units of transport boxes 2 that can be detachably assembled and spliced. In this embodiment, the number of connected transport boxes 2 is determined and installed according to the length of the transport route. The conveyor body 1 includes a head and a tail. The transport box 2 near the tail is provided with an inlet 21, and the transport box 2 near the head is provided with an outlet 22. Figure 3 and Figure 4 A partition 25 is installed in the transport box 2, a conveying device 3 for transporting materials from the tail to the head of the conveyor is installed in the conveyor body 1, and a screening component 4 for screening materials is installed on the transport box 2 near the head of the conveyor.

[0040] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4, put the material from the feed port 21 into the bottom of the transport box 2, and the transport device 3 transports the material steadily from the tail of the machine to the head of the machine. When it is about to reach the head of the machine, the material with qualified particle size is screened out of the transport box 2 by the screening component 4, and the material with unqualified size is continued to be transported to the discharge port 22 of the head of the machine, and the material with qualified particle size is screened out of the transport box 2 in advance, which reduces the qualified size of the material entering the subsequent processing stage, reduces the load and energy consumption of the material processing equipment, is conducive to saving energy, and at the same time can increase the speed of subsequent processing and crushing of the material and improve work efficiency.

[0041] The conveying device 3 includes a transmission main wheel 31, which is rotatably installed in the transport box 2 near the head of the machine. A support frame 32 is fixedly installed on the transport box 2 near the head of the machine, and a first motor 33 for controlling the rotation of the transmission main wheel 31 is fixedly installed on the support frame 32. A transmission auxiliary wheel 34 is rotatably installed on the transport box 2 near the tail of the machine. The transmission main wheel 31 and the transmission auxiliary wheel 34 are connected by a transmission chain 35, and a scraper 36 for pushing the material to move on the bottom surface of the transport box 2 is fixedly installed on the transmission chain 35.

[0042] When the material is placed on the bottom surface of the transport box 2, the first motor 33 controls the transmission main wheel 31 to rotate, and the transmission main wheel 31 controls the transmission chain 35 to move so that the scraper 36 pushes the material to move from the tail of the machine to the front of the machine on the bottom surface of the transport box 2. The scraper 36 pushes the material to move, so that the material can be gradually dispersed on the bottom surface of the transport box 2 during transportation, which is convenient for screening the material when approaching the front of the machine, thereby enhancing the screening effect of the material.

[0043] Reference Figure 2 , Figure 4 and Figure 5 The transport box 2 is provided with a screening outlet 24, and the screening assembly 4 includes a screening plate 41, which is fixedly mounted on the transport box 2, and is arranged at the screening outlet 24.

The screening horizontal bar 411 is arranged at one end close to the screening outlet 24 as follows: Figure 5 The V shape shown.

[0044] The scraper 36 pushes the material to move on the bottom surface of the transport box 2. When the material moves to the screening plate 41, the material with a particle size not exceeding the gap between the screening bars 411 will be screened between the screening bars 411 and fall out of the transport box 2 from the screening outlet 24. The screening bar 411 is set to a V-shape at one end close to the screening outlet 24, and the gap between the screening bar 411 at one end close to the screening outlet 24 is increased, so that the material can fall quickly from between the screening bars 411 after screening, and the smaller materials in the material can be screened out in advance, reducing the number of qualified materials entering the subsequent crushing section, reducing the load and energy consumption of the crushing equipment, and also speeding up the efficiency of the subsequent crushing stage.

[0049] Reference Figure 7 , Figure 8 and Fig. 9 When the material is screened on the screening plate 41, the driving unit pulls the slider 429 to slide on the loading block 428 by controlling the pull belt 4268. The slider 429 compresses the second spring 4283. The slider 429 drives the top block 434 to slide between the gaps of the screening horizontal bars 411. The material in the gaps of the screening horizontal bars 411 is moved by the top block 434, and the material is stirred to facilitate the exchange of the material position on the screening plate 41, so that the thicker material can be rolled close to the screening plate 41 to enhance the screening effect.

At this time, the rotating wheel 4261 pulls the drawstring 4268 to wind up on the rotating wheel 4261, and the drawstring 4268 can pull the slider 429 to slide on the loading block 428. The slider 429 compresses the second spring 4283, so that the top block 434 moves the material in the gap of the screening horizontal bar 411.

[0054] When the lever 425 rotates to the first stop block 4266, the first beveled surface on the first stop block 4266 pushes the slide bar 423 to slide in the rotating sleeve 422 in the direction away from the rotating sleeve 422, and the first bevel causes the lever 425 to disengage from the first stop block 4262. Because the rotating wheel 4261 is rotatably mounted on the second mounting plate 426, when the lever 425 disengages from the first stop block 4262, the lever 425 loses its restriction on the rotating wheel 4261, and the rotating wheel 4261 can rotate freely on the second mounting plate 426. When the second spring 4283 pushes the slider 429 to slide back on the loading block 428, the slider 429 also pulls the drawstring 4268 so that the drawstring 4268 drives the rotating wheel 4261 to rotate back, and during the return process of the slider 429, the slider 429 drives the top block 434 to flip the material on the return path. After the lever 425 rotates to leave the first stop block 4266, the first spring 424 pushes the first baffle 4231, and the first baffle 4231 drives the slide bar 423 to slide in the rotating sleeve 422 to make the lever 425 close to the rotating wheel 4261. The rotating sleeve 422 rotates to drive the lever 425 to rotate toward the second baffle 4263, and the second baffle 4263 is pushed to control the top block 434 to flip the material again, and when the lever 425 passes the position of the second stop block 4267, the top block 434 and the rotating wheel 4261 are returned to their original positions, and the material is flipped by the top block 434 by pushing the material back and forth between the gaps of the screening cross bars 411, so that the material in the thicker layer is flipped to be close to the screening plate 41 for sorting, thereby enhancing the screening effect of the material and helping to improve the efficiency of the screening scraper during use.

[0055] The implementation principle of the embodiment of the present application is as follows: the material is put into the transport box 2 from the feed port 21, and the transport device 3 transports the material steadily from the tail of the machine to the head of the machine. When the material is about to reach the head of the machine, the material with qualified particle size is screened out of the transport box 2 by the screening component 4, and the material with unqualified size is continuously transported to the discharge port 22 of the head of the machine, and the material with the required particle size is screened out of the transport box 2 in advance. When the material is screened by the screening plate 41, the second motor 4223 controls the rotation of the rotating sleeve 422 and the sliding rod 423, driving the top block 434 to slide between the gaps of the screening horizontal bars 411, and the top block 434 is driven to slide between the gaps of the screening horizontal bars 411. The block 434 moves the material in the gap between the screening bars 411, and stirs the material to facilitate the exchange of the material position on the screening plate 41. The top block 434 moves the material back and forth between the gap between the screening bars 411 to turn the material over, so that the thicker layer of material can be turned close to the screening plate 41 for sorting, thereby enhancing the screening effect of the material, which is beneficial to improving the efficiency of the screening scraper during use, reducing the number of qualified materials entering the subsequent processing stage, reducing the load and energy consumption of the material processing equipment, and saving energy. At the same time, it can increase the speed of subsequent processing and crushing of the material and improve work efficiency.

[0056] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
