Specific implementation

[0030] The utility model will be further described in connection with the embodiment shown in the drawings.

[0031] As Figure 1 shown, it is the schematic diagram of the automatic cleaning structure of the winnowing machine of the utility model, it includes first bin 1, second bin 2, mesh plate assembly, cleaning assembly, blowing assembly and drive assembly. First bin 1 is fixed on the workshop ground by support frame (specifically, the support frame is fixed on the workshop ground by screw fastening, first bin 1 is fixed on the top of support frame by screw fastening, the support frame is the existing conventional structure, adopts the steel plate welding into a frame structure, the support frame is not shown in the drawing). First bin 1 is supported away from the ground by support frame, ensures the normal installation of drive motor 3, avoids the installation interference problem of drive motor 3 and ground.

[0032] Second bin 2 is fixed on the top of first bin 1 by welding, and first bin 1 and second bin 2 are both hollow structures, that is, the internal space of first bin 1 and second bin 2 is communicated, to ensure that the waste such as sand in the mixed material (the mixed material is the mixed material of fine shavings, coarse shavings, sandstone and the like) falls down.

[0033] The motor shell of the driving motor 3 is fixed on the bottom of the first hopper 1 by screw fastening, and the driving shaft 4 of the driving motor 3 penetrates the first hopper 1 and the second hopper 2 upwards for driving the subsequent raking rod assembly 9, cleaning assembly and driving assembly to rotate. Since the driving shaft 4 of the driving motor 3 penetrates the bottom of the first hopper 1, a through hole is formed in the bottom of the first hopper 1, and a bearing seat (a bearing is installed in the bearing seat) is installed in the through hole. The driving shaft 4 of the driving motor 3 penetrates the bearing in the bearing seat, and the normal rotation of the driving shaft 4 is ensured under the action of the bearing.

[0034] The screen assembly includes an upper screen 10 and a lower screen 11, and the upper screen 10 and the lower screen 11 are fixed in the second hopper 2 (specifically, the outer side wall of the upper screen 10 and the inner side wall of the second hopper 2 are welded together by an angle plate, and the outer side wall of the lower screen 11 and the inner side wall of the second hopper 2 are also welded together by an angle plate, so the upper screen 10, the lower screen 11 and the second hopper 2 are fixed together and will not rotate with the driving shaft 4).

[0035] As shown in Figure 1 The upper screen 10 is located above the lower screen 11, and the mixed material (the mixed material is a mixture of fine shavings, coarse shavings, sand and the like) is first distributed on the upper screen 10. The fine shavings in the mixed material pass upwards into the cyclone separator through the pipeline; the coarse shavings in the mixed material are raked to the coarse shavings box on one side by the raking rod assembly 9 for secondary crushing treatment; and the sand waste in the mixed material falls on the lower screen 11 through the upper screen 10, and finally falls into the first hopper 1 through the lower screen 11.

[0036] The top of the second hopper 2 is connected with a pipeline, and under the blowing action of the external fan, the material on the upper screen 10 is boiled up, and the fine shavings in the suspended state are lighter and are sent into the subsequent cyclone separator through the pipeline along with the airflow.

[0037] Since the driving shaft 4 of the driving motor 3 extends upwards and penetrates the lower screen 11 and the upper screen 10 in sequence, the center of the lower screen 11 and the center of the upper screen 10 are both provided with a hole, and a bearing seat is installed in the hole. The driving shaft 4 of the driving motor 3 penetrates the bearing seats of the upper screen and the lower screen, and the rotation of the driving shaft 4 is more stable.

[0038] The connecting rods are multiple, and the outer end faces of the connecting rods are fixed on the inner side wall of the second hopper 2 by welding. The inner end faces of the connecting rods are welded with bearing seat supporting plates, and the bearing seats are fixedly installed on the bearing seat supporting plates. The driving shaft 4 of the driving motor 3 also penetrates the bearing seats, further increasing the stability of the rotation of the driving shaft 4.

[0039] By setting the connecting rod structure, the structural strength of the second bin 2 is improved, and the second bin 2 is prevented from being bent inward to interfere with the rotating and raking action of the raking rod assembly 9 (the connecting rod is a rod-shaped structure, so the connecting rod structure fixed on the inner wall of the second bin 2 will not affect the falling of waste such as sand and gravel).

[0040] The raking rod assembly 9 is fixed at the end of the drive shaft 4 away from the drive motor 3. When the drive motor 3 drives the drive shaft 4 to rotate, the drive shaft 4 drives the raking rod assembly 9 to rotate, so as to rake the mixed materials on the upper screen plate 10. This can prevent the materials from accumulating and make the materials evenly distributed on the full surface of the upper screen plate 10, thereby ensuring that the fine shavings in the mixed materials are in a suspended state under the action of the airflow below, and then enter the cyclone separator along with the airflow through the pipeline for separation.

[0041] The structure and fixing method of the raking rod assembly 9 are described in the following patent: Application No. 202323146210.5, Patent Name "A new raking device for a sorting machine".

[0042] The upper screen hole ring is provided through the upper screen plate 10, the lower screen hole ring is provided through the lower screen plate 11, and the diameter of the upper screen hole is smaller than that of the lower screen hole. The mixed materials are initially distributed on the upper screen plate 10. Under the action of the raking rod assembly 9 and the airflow below, the fine shavings in the mixed materials are in a suspended state due to their lightness, and then enter the cyclone separator along with the airflow through the pipeline for separation; the coarse shavings in the mixed materials cannot pass through the upper screen hole nor be blown upward, so they are discharged from the opening in the side wall of the second bin 2 to the coarse shaving box under the raking of the raking rod assembly 9 for subsequent crushing treatment; the sand in the mixed materials falls through the upper screen hole of the upper screen plate 10 to the lower screen plate 11.

[0043] Since the diameter of the lower screen hole is larger than that of the upper screen hole, the sand is prevented from being stuck in the lower screen hole of the lower screen plate 11 as much as possible. However, the falling sand has different shapes, so some long strip-shaped and triangular sand will still be stuck on the lower screen plate 11. Therefore, the lower screen plate 11 needs to be further cleaned by the cleaning assembly to change the placement state of the sand on the lower screen plate 11, so as to ensure that the sand falls smoothly into the first bin 1.

[0044] The side wall of the second bin 2 is provided with an opening, and the coarse shaving box is placed outside the opening. The coarse shavings in the mixed materials are raked by the raking rod assembly 9 and fall into the coarse shaving box under the action of centrifugal force, for subsequent crushing treatment (such as Figure 1 As shown, the raking rod assembly 9 and the upper surface of the upper screen plate 10 leave a small gap, so the sand in the mixed materials will not be raked by the raking rod assembly 9 into the coarse shaving box).

[0045] The cleaning assembly is fixed on the driving shaft 4 of the driving motor 3 and rotates synchronously with the driving shaft 4 to clean the sand and stones on the lower screen plate 11, thereby changing the placement state of the sand and stones on the lower screen plate 11 and ensuring that the sand and stones fall smoothly into the first bin 1. Figure 3 , 4 As shown in the drawings, the cleaning assembly comprises a first clamping arc plate 13, a second clamping arc plate 14, a first clamping groove 15, a supporting plate 16, a pressing plate 17, a brush plate 18 and a brush 19. The first clamping arc plate 13 and the second clamping arc plate 14 have the same shape structure, the inner side of the first clamping arc plate 13 and the second clamping arc plate 14 is formed with the first clamping groove 15, the first clamping groove 15 is held on the driving shaft 4 of the driving motor 3, a fastening bolt is passed through the first clamping arc plate 13 and the second clamping arc plate 14, and the first clamping arc plate 13 and the second clamping arc plate 14 are fixed on the driving shaft 4 by means of a fastening nut on the other side.

[0046] The supporting plate 16 is welded on the side of the second clamping arc plate 14 away from the first clamping arc plate 13, the brush plate 18 is clamped between the supporting plate 16 and the pressing plate 17, a fastening bolt is passed through the supporting plate 16, the brush plate 18 and the pressing plate 17, and the fixing connection of the three is completed by means of a fastening nut on the other side. The brush 19 is arranged at the bottom of the brush plate 18 (specifically, a plurality of brush holes are formed at the bottom of the brush plate 18, the brush 19 is inserted into the brush hole, and then glue is dropped around the brush hole to realize the connection of the brush 19 and the brush plate 18).

[0047] When the driving motor 3 drives the driving shaft 4 to rotate, the driving shaft 4 drives the cleaning assembly to rotate synchronously, the sand and stones on the lower screen plate 11 are cleaned by the brush 19, thereby changing the placement state of the sand and stones on the lower screen plate 11, avoiding the sand and stones from being stuck on the lower screen holes of the lower screen plate 11, and ensuring that the sand and stones fall smoothly into the first bin 1.

[0048] As shown in the drawings, two groups of cleaning assemblies are installed on the driving shaft 4, one group of which is used to clean the sand and stones on the lower screen plate 11, and the other group of which is used to clean the sand and stones falling on the bottom of the inner side of the first bin 1, facilitating the cleaning of the sand and stones in the first bin 1 (a cleaning window is installed on the bottom side wall of the first bin 1 through a hinge, facilitating the regular cleaning of the sand and stones inside by the operator). Figure 1

[0049] The upper screen holes and the lower screen holes are staggered, so that the falling sand and stones are buffered by the lower screen plate 11, avoiding the sand and stones from directly falling into the first bin 1 and avoiding the damage to the bottom structure of the first bin 1.

[0050] During actual installation, the height of the cleaning assembly can be adjusted appropriately to change the distance between the brush 19 and the lower screen plate 11 and the first bin 1, which can be adjusted according to different sand and stones, thereby improving the universality of the sorting machine.

[0051] ​The blowing assembly has two groups, which are fixed on the driving shaft 4 of the driving motor 3 and rotate synchronously with the driving shaft 4. The blowing assembly faces upward to the lower screen plate 11 and the upper screen plate 10 and intermittently blows upward to the lower screen plate 11 and the upper screen plate 10 to avoid the clogging of the screen plates (the blowing assembly does not blow upward to the lower screen plate 11 and the upper screen plate 10 all the time, but intermittently blows upward to the lower screen plate 11 and the upper screen plate 10. If the blowing assembly blows upward to the lower screen plate 11 and the upper screen plate 10 all the time, it will affect the falling of the sand and stone in the mixture).

[0052] As shown in Figures 5-7 The blowing assembly includes a third clamping arc plate 20, a fourth clamping arc plate 21, a second clamping groove 22, a main air inlet hole 23, a secondary air inlet hole 24, a main air pipe 25, a side air pipe 26 and a nozzle 27. The third clamping arc plate 20 and the fourth clamping arc plate 21 have the same shape structure. The inner side of the third clamping arc plate 20 and the fourth clamping arc plate 21 is formed with the second clamping groove 22, which is held on the driving shaft 4 of the driving motor 3. The third clamping arc plate 20, the fourth clamping arc plate 21 and the driving shaft 4 are fixed together by passing a fastening bolt through the third clamping arc plate 20 and the fourth clamping arc plate 21 and additionally using a fastening nut on the other side.

[0053] The main air pipe 25 is fixed on one side of the fourth clamping arc plate 21 by welding. The nozzle 27 is integrally connected to the main air pipe 25 and faces upward to the lower screen plate 11 and the upper screen plate 10 to blow the clogged materials of the lower screen plate 11 and the upper screen plate 10 and ensure the normal falling of the materials.

[0054] The side air pipe 26 is fixed on one side of the fourth clamping arc plate 21 by welding and is connected with the main air pipe 25. The side air pipe 26 and the main air pipe 25 are both hollow structures, and the two ends of the side air pipe 26 are close to the two ends of the main air pipe 25 to ensure the uniform pressure of the nozzles 27 on both sides.

[0055] The main air inlet hole 23 penetrates through the fourth clamping arc plate 21 and is connected with the main air inlet pipe 8. The secondary air inlet hole 24 penetrates through the fourth clamping arc plate 21 and is connected with the secondary air inlet pipe 24. During blowing, the gas enters the main air pipe 25 and the side air pipe 26 from the main air inlet hole 23 and the secondary air inlet hole 24 respectively and is then sprayed from the nozzle 27 to blow the clogged materials of the lower screen plate 11 and the upper screen plate 10 and ensure the normal falling of the materials. The side air pipe 26 is arranged to ensure the uniform pressure of the nozzle 27 (if only the main air pipe 25 is arranged, the pressure of the nozzle 27 far from the fourth clamping arc plate 21 on the main air pipe 25 is less than the pressure of the nozzle 27 close to the fourth clamping arc plate 21, which may not blow the materials stuck in the screen holes, thereby affecting the winnowing efficiency of the materials).

[0056] As shown in Figure 2As shown, the air groove 5 is arranged on the side of the driving shaft 4 away from the driving motor 3, the air outlet 6 is arranged on the side wall of the driving shaft 4 and is communicated with the main air inlet 23 and the auxiliary air inlet 24 respectively, so as to ensure the circulation of the gas (specifically, the driving shaft 4 is provided with two groups of air outlets 6 in the vertical direction, which are matched with two groups of air blowing assemblies respectively; and each group of air outlets 6 has two air outlets for matching the main air inlet 23 and the auxiliary air inlet 24).

[0057] The protective cover 7 is arranged on the top of the driving shaft 4 through the rotary valve, so as to avoid that the impurities and dust in the outside enter the air groove 5 and block the air groove 5. The air inlet pipe 8 is fixedly connected to the side wall of the protective cover 7 and is communicated with the air groove 5 in the driving shaft 4, the end of the air inlet pipe 8 away from the protective cover 7 is connected with the compressed air through the connecting pipe, which is used for intermittently blowing air into the air groove 5, and then blowing air to the upper and lower screen plates through the nozzle 27, so as to avoid that the sand and stones block the screen holes (specifically, the protective cover 7 is provided with a rotary valve, which is fixedly connected to the top of the driving shaft 4. Through the rotary valve, when the driving motor 3 drives the driving shaft 4 to rotate, the air inlet pipe 8 is not twisted and broken. Because the air inlet pipe 8 is fixed, the valve core of the rotary valve rotates coaxially. The rotary valve can be selected from the commercially available rotary joint).

[0058] Further, the fan is connected to the side wall of the first bin 1 through the pipeline. When the mixed material is air separated, the fan blows air into the first bin 1, so as to separate the fine shaving material in the mixed material.

[0059] The cleaning principle of the automatic cleaning structure of the air separator is as follows:

[0060] Firstly, the mixed material is poured onto the upper screen plate 10, the driving motor 3 is started, the driving shaft 4 drives the stirring rod assembly 9 to rotate, which can prevent the material from accumulating and make the material uniformly distributed on the upper surface of the upper screen plate 10, the fan is started, the airflow enters the first bin 1 from the pipeline, passes through the screen plate upwards and is uniformly distributed on the entire cross section of the suspension chamber, and the material on the upper screen plate 10 boils up under the action of the airflow. Because the fine shaving material is lighter, the fine shaving material in the suspension state passes through the pipeline upwards and enters the cyclone separator for separation; the coarse shaving material in the mixed material cannot pass through the upper screen hole and cannot be blown away upwards, so it is discharged from the opening in the side wall of the second bin 2 to the coarse shaving box under the stirring of the stirring rod assembly 9 for subsequent crushing treatment; the sand and stones in the mixed material are heavier, so they pass through the upper screen hole of the upper screen plate 10 and fall onto the lower screen plate 11, and finally fall into the first bin 1 under the cleaning of the cleaning assembly.

[0061] Under the cooperation of the cleaning assembly and the air blowing assembly, the screen plate can be prevented from being blocked, so that the efficiency of air separation is improved, and the time and cost consumed for manual cleaning are saved.

[0062] The above examples are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and to implement it, and cannot limit the protection scope of the present application. Any equivalent changes or modifications made according to the spirit and essence of the present application shall be covered within the protection scope of the present application.
