Description

Technical Field

[0001] The present invention relates to the technical field of color sorters, and in particular to an air sorting device for a color sorter. Background Art

[0002] When the color sorter is screening grain materials, the materials sometimes contain a lot of impurities, such as dust, branches, leaves, powder, etc., which will affect the normal operation of the color sorter. The traditional solution is to add a dust suction system during the falling process of the color sorter material, but the amount of impurities handled by a single dust suction system is small and the effect is not very good. The existing air separation device for the color sorter has the problem of material blockage at the feeding point when in use. Summary of the invention

[0003] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a wind sorting device for a color sorter.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] The fan is then moved along the cam surface to move the fan upwards to move the material into the cam, and the fan is moved along the cam surface to move the material into the cam.

[0006] Preferably, the mounting mechanism comprises a first mounting wing mounted on the side of the windshield; and further comprises a second mounting wing mounted on the side of the feeding shell, and the second mounting wing is connected to the first mounting wing via a mounting spring.

[0007] Preferably, a vertically arranged guide rod is installed on a side of the first mounting wing close to the second mounting wing, and an end of the guide rod away from the first mounting wing extends to the bottom of the second mounting wing for guiding the shaking of the windshield.

[0008] Preferably, one end of the screen plate close to the feeding shell extends to the outside of the wind tube through the opening of the feeding port; the bottom of the screen plate is connected to the inner wall of the feeding port and the inner wall of the discharge port through a spring; a pushing component is installed at the bottom of the feeding shell, and the position of the pushing component corresponds to the position of the screen plate, which is used to push the screen plate during the shaking process of the feeding shell.

[0009] Preferably, an air suction pipe is installed at one end of the wind tube away from the fan to extract impurities blown up in the wind tube.

[0010] Preferably, it also includes a conveyor belt for conveying the materials that fall through the discharge opening after air selection.

[0011] Preferably, it also includes a camera for photographing and identifying materials transported on the conveyor belt.

[0012] Preferably, the air volume regulating mechanism comprises a rotating shaft movably mounted in the air cylinder, the rotating shaft being located between the screening plate and the fan; movable parts are mounted on the rotating shaft; and a driving part is also included for driving the rotating shaft to rotate.

[0013] Preferably, an airflow dispersion mesh plate is installed inside the air duct, and the airflow dispersion mesh plate is installed between the sieve plate and the rotating shaft to disperse the airflow in the air duct.

[0014] The beneficial effects of the present invention are:

[0015] When in use, the vibration motor drives the feeding shell to vibrate, so that the material in the feeding shell slides from the opening of the feeding port into the air duct, and the material fed into the air duct slides on the screening plate. At the same time, the fan blows air into the inside of the air duct, and the airflow blows the material sliding down the screening plate, and the light-weight impurities mixed in the material are blown up by the airflow, which has the effect of air separation and dust removal. The air volume in the air duct can be adjusted by the air volume adjustment mechanism, and one end of the feeding shell is located in the opening of the feeding port. In order to meet the shaking amplitude of the feeding shell, the opening inner diameter of the feeding port is larger than the outer diameter of the feeding shell. During the feeding and air separation process, the wind shield plate blocks the opening of the feeding port to prevent airflow and dust from overflowing through the opening of the feeding port, and in the process of the feeding shell driving the wind shield plate to shake, the material shifting component shifts the opening of the feeding port, which effectively prevents the opening of the feeding port from being blocked, and can also shift and disperse the material sliding down at the opening of the feeding port, thereby improving the effect of air separation.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figures 1 to 3 A wind sorting device for a color sorter comprises a frame 1, a fan 2 is installed inside the frame 1, and a wind tube 9 is installed at the air outlet end of the fan 2; a feeding shell 12 is installed on the frame 1 through a mounting support 14, and a vibration motor 13 is installed on the feeding shell 12 to drive the feeding shell 12 to vibrate; a feeding port 18 is provided on the side of the wind tube 9 close to the feeding shell 12, and a feeding port 15 is provided on the side of the feeding shell 12 close to the wind tube 9 for feeding into the wind tube 9; a discharge port 11 is provided on the side of the wind tube 9 away from the feeding shell 12, and an inclined screening plate is elastically installed inside the discharge port 11 10, used for screening the material 6 fed into the air duct 9; the feeding shell 12 extends from the feeding port 18 to one side of the interior of the air duct 9, and is elastically installed with a wind shield 16 through a mounting mechanism 20, which is used for shielding the opening of the feeding port 18 to prevent the airflow and dust from overflowing to the outside of the air duct 9 through the opening of the feeding port 18 during air selection; a material shifting component 17 is installed at the bottom of the wind shield 16, and the position of one end of the material shifting component 17 away from the wind shield 16 corresponds to the opening position of the feeding port 15, and is used for clearing the opening of the feeding port 15; it also includes an air volume regulating mechanism 3, which is used for regulating the air volume in the air duct 9.

[0022] When in use, the vibration motor 13 drives the feeding shell 12 to vibrate, so that the material 6 in the feeding shell 12 slides from the opening of the feeding port 15 into the air duct 9, and the material 6 fed into the air duct 9 slides on the screening plate 10. At the same time, the fan 2 blows air into the inside of the air duct 9, and the airflow blows the material 6 sliding on the screening plate 10. The light-weight impurities mixed in the material 6 are blown up by the airflow, which has the effect of air separation and dust removal. The air volume in the air duct 9 can be adjusted by the air volume adjustment mechanism 3, and one end of the feeding shell 12 is located at the feeding port 18. In the opening, in order to meet the shaking amplitude of the feeding shell 12, the inner diameter of the opening of the feeding port 18 is larger than the outer diameter of the feeding shell 12. During the feeding and air separation process, the wind shield 16 blocks the opening of the feeding port 18 to prevent airflow and dust from overflowing through the opening of the feeding port 18. In the process of the feeding shell 12 driving the wind shield 16 to shake, the material shifting component 17 shifts the opening of the feeding port 15, which effectively prevents the opening of the feeding port 15 from being blocked, and can also shift and disperse the material that slides down from the opening of the feeding port 15, thereby improving the air separation effect.

[0023] As a preferred embodiment of the present invention, the mounting mechanism 20 includes a first mounting wing 201 mounted on the side of the wind shield 16; and also includes a second mounting wing 203 mounted on the side of the loading shell 12. The second mounting wing 203 and the first mounting wing 201 are connected by a mounting spring 202. During the shaking of the loading shell 12, the wind shield 16 shakes along with the shaking of the loading shell 12. At the same time, the shaking amplitude of the wind shield 16 is inconsistent with that of the loading shell 12 under the action of its own gravity and the elastic action of the mounting spring 202. At this time, the wind shield 16 moves relative to the loading shell 12, that is, the material shifting component 17 is displaced relative to the opening of the loading port 15, thereby realizing the shifting of the material at the opening of the loading port 15 by the material shifting component 17.

[0024] As a preferred embodiment of the present invention, a vertically arranged guide rod 21 is installed on one side of the first mounting wing 201 close to the second mounting wing 203, and the guide rod 21 extends from one end away from the first mounting wing 201 to the bottom of the second mounting wing 203, and is used to guide the shaking of the wind shield 16 to ensure that the wind shield 16 and the material removing component 17 move in the vertical direction relative to the loading shell 12.

[0025] As a preferred embodiment of the present invention, one end of the screening plate 10 close to the feeding housing 12 extends to the outside of the air duct 9 through the opening of the feeding port 18; the bottom of the screening plate 10 is connected to the inner walls of the feeding port 18 and the discharging port 11 by springs; a jacking member 19 is installed at the bottom of the feeding housing 12, and the position of the jacking member 19 corresponds to the position of the screening plate 10, and is used to jack the screening plate 10 during the shaking process of the feeding housing 12. During the shaking process of the feeding housing 12, the jacking member 19 jacks the screening plate 10 as the feeding housing 12 rises and falls and shakes, so that the screening plate 10 shakes accordingly, promoting the dispersion of the material 6 sliding on the screening plate 10 and improving the air separation efficiency.

[0026] As a preferred embodiment of the present invention, an air suction pipe 8 is installed at one end of the air duct 9 far from the blower 2, and is used to extract the impurities blown up in the air duct 9.

[0027] As a preferred embodiment of the present invention, it further includes a conveyor belt 5, which is used to convey the material 6 that falls through the opening of the discharging port 11 after air separation.

[0028] As a preferred embodiment of the present invention, it further includes a camera 7, which is used to photograph and identify the material 6 conveyed on the conveyor belt 5.

[0029] As a preferred embodiment of the present invention, the air volume adjusting mechanism 3 includes a rotating shaft 31 movably installed in the air duct 9, and the rotating shaft 31 is located between the screening plate 10 and the blower 2; a movable member 33 is installed on the rotating shaft 31; it further includes a driving member 32, which is used to drive the rotating shaft 31 to rotate. The material 6 conveyed on the conveyor belt 5 can be photographed and identified by the camera 7. When the impurity content in the material 6 conveyed on the conveyor belt 5 is identified to exceed the preset value, the driving member 32 drives the rotating shaft 31 to rotate, and adjusts the air volume in the air duct 9 by adjusting the inclination degree of the movable member 33 in the air duct 9, which is flexible and convenient to use.

[0030] As a preferred embodiment of the present invention, an air flow dispersion grid plate 4 is installed inside the air duct 9, and the air flow dispersion grid plate 4 is installed between the screening plate 10 and the rotating shaft 31, and is used to disperse the air flow in the air duct 9, ensuring that the air flow adjusted by the movable member 33 can uniformly contact the bottom of the screening plate 10, and ensuring uniform and effective blowing and air separation of the material 6 sliding on the screening plate 10.

[0031] When in use, the vibration motor 13 drives the feeding shell 12 to vibrate, so that the material 6 in the feeding shell 12 slides from the opening of the feeding port 15 into the wind tube 9, and the material 6 fed into the wind tube 9 slides on the screening plate 10. At the same time, the fan 2 blows air into the inside of the wind tube 9, and the airflow blows the material 6 sliding on the screening plate 10. The light-weight impurities mixed in the material 6 are blown up by the airflow, which has the effect of air separation and dust removal. The air volume in the wind tube 9 can be adjusted by the air volume adjustment mechanism 3, and one end of the feeding shell 12 is positioned In the opening of the feeding port 18, in order to meet the shaking amplitude of the feeding shell 12, the inner diameter of the opening of the feeding port 18 is larger than the outer diameter of the feeding shell 12. During the feeding and air selection process, the wind shield 16 blocks the opening of the feeding port 18 to prevent airflow and dust from overflowing through the opening of the feeding port 18. In the process of the feeding shell 12 driving the wind shield 16 to shake, the material shifting component 17 shifts the opening of the feeding port 15, effectively avoiding the situation that the opening of the feeding port 15 is blocked, and the material that slides off the opening of the feeding port 15 can be moved. The material is dispersed by stirring to improve the effect of air selection; during the shaking of the feeding shell 12, the wind shield 16 shakes with the shaking of the feeding shell 12. At the same time, the wind shield 16 is inconsistent with the shaking amplitude of the feeding shell 12 under the action of its own gravity and the elastic action of the installation spring 202. At this time, the wind shield 16 moves relative to the feeding shell 12, that is, the material shifting component 17 is displaced relative to the opening of the feeding port 15, so that the material shifting component 17 shifts the material at the opening of the feeding port 15; during the shaking of the feeding shell 12, the top moving As the feeding shell 12 is lifted and lowered and shaken, the component 19 pushes the screening plate 10, causing the screening plate 10 to shake accordingly, thereby promoting the dispersion of the material 6 sliding down the screening plate 10 and improving the air selection efficiency; the material 6 transported on the conveyor belt 5 can be photographed and identified by the camera 7. When it is identified that the amount of impurities in the material 6 transported on the conveyor belt 5 exceeds the preset value, the driving component 32 drives the rotating shaft 31 to rotate, and the air volume in the air duct 9 is adjusted by adjusting the inclination of the movable component 33 in the air duct 9. It is flexible and convenient to use.
