Abstract
Description
Technical Field
[0001] This invention belongs to the field of vegetable air separation technology, and more specifically, relates to a vegetable air separation device. Background Technology
[0002] Air separators are machines used to separate light and heavy materials by blowing air. They are widely used in the air separation of various fruits and vegetables to separate fruit bodies from miscellaneous leaves. The application of air separators greatly saves production time for enterprises.
[0003] Chinese Patent No. (CN202211468305.6) discloses a self-circulating air separator for dehydrated vegetables, relating to the field of vegetable processing technology. The separator includes a fixed frame with an induced draft fan on it. An mounting frame is located on the left side of the air separator chamber. The sliding block, in conjunction with the elastic action of a first compression spring, causes the vibrating screen to float up and down within the air separator chamber. However, the fruit and leaves cannot be sufficiently dispersed, resulting in low sorting efficiency. Furthermore, the simple screen structure at the recovery box and discharge port allows material to easily accumulate on the screen surface, reducing screening efficiency.
[0004] The above solution still has the following drawbacks during implementation:
[0005] 1. The above solution only vibrates the material through a vibrating screen during implementation, which cannot make the material disperse more fully. When too much material is put in at one time, the dispersion effect is limited, and it is easy to accumulate and make it difficult to remove impurities, thus reducing the efficiency of air separation.
[0006] 2. The above solution uses a blower to separate debris and materials, but the air outlet area is fixed and cannot be quickly adjusted. When dealing with different vegetable varieties, only the blower force can be adjusted, which reduces the flexibility of the equipment and cannot meet the needs of use.
[0007] 3. When using a vibrating screen, the entire air separator will also vibrate. The above solution lacks protection, and the overall structural impact will greatly reduce its service life. In addition, the vibrating screen is fixed and not easy to disassemble, making it inconvenient for later maintenance and cleaning.
[0008] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a vegetable air separation device in order to achieve a more practical value. Summary of the Invention
[0009] To address the aforementioned technical problems, this invention provides a vegetable air separation device.

[0012] Preferably, two pairs of springs are fixedly connected inside the support frame, and both pairs of springs are fixedly connected to the machine frame. Two rubber pads are fixedly connected inside the support frame. A slot is provided on the lower surface of the machine frame. Two limiting grooves are provided on the inner wall of the machine frame. Both limiting grooves are slidably connected to the screen. A set of limiting grooves is provided on the rear surface of the front fixed plate of the two fixed plates. The set of limiting grooves is movably engaged with the limiting block.
[0013] Preferably, a locking block is fixedly connected to the left surface of each of the two fixing plates, and a screw is threaded onto the surface of each of the two fixing plates. The two locking blocks are respectively movably engaged with the two limiting grooves. A spring is fixedly connected to the rear surface of the limiting block, and the spring is fixedly connected to the locking groove. A locking groove is provided on the right surface of the locking groove. A handle block is fixedly connected to the right surface of the limiting block, and the handle block is movably engaged with the locking groove.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] In this invention, two pairs of springs are fixedly connected between the support frame and the machine frame. When the two pairs of springs are vibrated, they will resonate. The screen in the resonant state can separate vegetables and impurities more quickly, thereby improving the overall screening efficiency. Two rubber pads are provided on the support frame. The rubber pads can reduce the impact force generated when the machine frame comes into contact with the support frame during vibration, reduce the wear of both, reduce noise, and improve the overall service life of the equipment.

[0017] In this invention, the rotating screw drives the baffle plate attached to it to move. The baffle plate is movably engaged in the connecting plate, while the servo motor rotates and connects to the connecting plate. As the baffle plate moves downward, it blocks the protective net, thereby adjusting its air outlet area. Appropriately adjusting the air outlet area can improve the efficiency of air separation and reduce the missed selection of light impurities and the mis-discharge of heavy materials.
[0018] In this invention, the inner wall of the air separation box is equipped with a protective net for protection. The airflow generated by the blower blows the light impurities on the conveyor belt into the collection box through the conveying pipe, while the heavier vegetables remain on the conveyor belt and continue to move until they slide off the second slider for collection. The separated impurities and unqualified vegetables are collected and processed through the collection box. The entire screening process can be automated, reducing manual intervention and improving efficiency and safety. Attached Figure Description

[0027] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.
[0028] Please see Figures 1-7This invention provides a vegetable air separation device, including a support frame 1, a machine frame 2 mounted above the support frame 1, a connecting block 3 fixedly connected to the upper surface of the machine frame 2, a feed inlet 4 fixedly connected to the upper surface of the connecting block 3, an air separation box 8 mounted on the right side of the support frame 1, a conveyor belt 9 mounted inside the air separation box 8, a fixing frame 7 fixedly connected to the right surface of the air separation box 8, a fan 6 fixedly mounted on the upper surface of the fixing frame 7, a vibration motor 12 fixedly mounted on the front surface of the machine frame 2, a screen 5 mounted inside the machine frame 2, and a slider 14 fixedly connected to the right surface of the screen 5. 2. Two fixing plates 28 are provided on the right surface. A limit strip 22 is provided between the two fixing plates 28. A fixing block 34 is fixedly connected inside the limit strip 22. A slot 4 39 is opened on the front surface of the fixing block 34. A limit block 2 37 is movably engaged in the slot 4 39. A fixing box 17 is provided on the left side of the air classifier box 8. A collection box 11 is provided inside the fixing box 17. A conveying pipe 40 is fixedly connected between the air classifier box 8 and the fixing box 17. A servo motor 10 is fixedly installed on the left surface of the air classifier box 8. The output shaft of the servo motor 10 is fixedly connected to the connecting shaft of the conveyor belt 9. When air separation of vegetables is required, the vibration motor 12 is started to drive the frame 2 to vibrate. During the vibration of the frame 2, the screen 5 will also vibrate. At this time, the vegetables to be air separated are put into the feed inlet 4. The vegetables fall onto the screen 5 and are driven by the vibration motor 12 to jump. Some impurities contained in the vegetables will be screened through the screen 5 and fall into the collection box 11 below for collection. The overall inclined design of the frame 2 causes the vegetables to move to the right during vibration and screening. The frame 2 is movably locked into the support frame 1 by two fixed limit blocks 23. Two pairs of springs 25 are fixedly connected between the support frame 1 and the frame 2. When the two pairs of springs 25 are vibrated, they will resonate. The screen 5 in the resonant state can separate vegetables and impurities more quickly, thereby improving the overall screening efficiency. Two rubber pads 26 are set on the support frame 1. The rubber pads 26 can reduce the impact force generated when the frame 2 comes into contact with the support frame 1 during vibration, reduce the wear of both, reduce noise, and improve the overall service life of the equipment.
[0029] A connecting pipe 13 is fixedly installed on the right surface of the air classifier box 8. A slider 21 is fixedly connected to the front surface of the air classifier box 8. A connecting pipe 28 is fixedly connected between the air outlet of the blower 6 and the connecting pipe 13. A protective net 16 and a connecting plate 15 are fixedly connected to the inner wall of the air classifier box 8. A baffle 19 is movably engaged inside the connecting plate 15. A screw 20 is rotatably connected to the surface of the connecting plate 15. The screw 20 is threadedly engaged with the baffle 19. Two slots 24 are opened on the inner wall of the support frame 1. Limiters are fixedly connected to both the front and rear sides of the frame 2. Block 123, two limiting blocks 123 are respectively engaged with two slots 124. The vegetables move to the right with the screen 5. The right side of the frame 2 is equipped with limiting strips 22 for blocking. The limiting strips 22 promote the uniform falling of the vegetables on the slider 14, avoiding excessive falling at one time, and also facilitating the subsequent air separation process. For vegetables of different varieties and sizes, the position of the limiting strips 22 needs to be adjusted to ensure that they are at the optimal blocking height, which can both ensure the falling of the vegetables and block them to ensure the uniform falling.
[0030] Two pairs of springs 25 are fixedly connected inside the support frame 1, and both pairs of springs 25 are fixedly connected to the machine frame 2. Two rubber pads 26 are fixedly connected inside the support frame 1. A slot 30 is opened on the lower surface of the machine frame 2, and two limiting grooves 29 are opened on the inner wall of the machine frame 2. Both limiting grooves 29 are slidably connected to the screen 5. A set of limiting grooves 33 is opened on the rear surface of the front fixed plate 28, and both sets of limiting grooves 33 are movably engaged with the limiting block 37. A fixing block 34 is set on the limiting strip 22. Pulling the handle block 36 backward will move the limiting block 37 fixed to it, compressing the spring 35. At this time, the limiting block 34 is engaged with the limiting block 37. 37 will disengage from the set of limiting grooves 33 opened on the fixed plate 28, opening the limit. The limiting bar 22 can move up and down to the desired position. After moving up and down, the spring force of the second spring 35 drives the limiting block 37 to reset. At this time, the limiting bar 22 and the two fixed plates 28 are in a limited fixed state. The two fixed plates 28 are fixed to the frame 2 by screws 32. After the two fixed plates 28 are removed, the screen 5 can also be opened and disassembled. The overall detachable design facilitates later cleaning and maintenance. The height of the limiting bar 22 is easy to adjust and can be quickly adjusted according to different vegetable sizes and screening requirements, improving the adaptability and flexibility of the equipment.
[0031] Both fixed plates 28 have locking blocks 31 fixedly connected to their left surfaces, and screws 32 are threaded onto the surfaces of both fixed plates 28. The two locking blocks 31 are respectively engaged with the two limiting grooves 29. A spring 35 is fixedly connected to the rear surface of the limiting block 37, and the spring 35 is fixedly connected to the slot 39. A slot 38 is opened on the right surface of the slot 39. A handle block 36 is fixedly connected to the right surface of the limiting block 37, and the handle block 36 is engaged with the slot 38. The vegetables slide down the slider 14 into the air separator 8 on the right side. The servo motor 10 is started, and its output shaft drives the connecting shaft of the conveyor belt 9 to rotate, thereby driving the conveyor belt 9 to rotate. The fan 6 is started, and the airflow generated is transported into the air separator 8 through the connecting pipe 18 and the connecting pipe 13. A protective net 16 is provided on the inner wall of the air separator 8 for protection. The airflow generated by the blower 6 blows light impurities on the conveyor belt 9 through the conveying pipe 40 into the collection box 11, while heavier vegetables remain on the conveyor belt 9 and continue to move until they slide off the slider 21 for collection. The separated impurities and unqualified vegetables are collected and processed through the collection box 11. The screw 20 is rotated to drive the baffle 19 fitted on it to move. The baffle 19 is movably locked in the connecting plate 15, while the servo motor 10 is rotated and connected to the connecting plate 15. As the baffle 19 moves downward, it blocks the protective net 16, thereby adjusting its air outlet area. Appropriate adjustment of the air outlet area can improve the efficiency of air separation, reduce the missed screening of light impurities and the mis-discharge of heavy materials. In addition, the entire screening process can be automated, reducing manual intervention and improving efficiency and safety.
[0032] Working principle:
[0033] The first step involves starting the vibration motor 12 to vibrate the frame 2 when vegetables need to be air-separated. During this vibration, the frame 2 also vibrates the screen 5. The vegetables to be air-separated are then fed into the inlet 4. As the vegetables fall onto the screen 5, they undergo a jumping motion driven by the vibration motor 12. Impurities within the vegetables are separated by the screen 5 and fall into the collection box 11 below for collection. The frame 2 is designed with an overall tilt, so the vegetables move to the right during the vibration separation. The frame 2 is movably engaged with the support frame 1 by two fixed limiting blocks 23. Two pairs of springs 25 are fixedly connected between the support frame 1 and the frame 2. These springs resonate during vibration, allowing the screen 5 to separate vegetables and impurities more quickly, thus improving overall screening efficiency. Two rubber pads 26 are installed on the support frame 1. These pads reduce the impact force generated when the frame 2 contacts the support frame 1 during vibration, reducing wear and tear, noise, and extending the overall service life of the equipment.
[0034] In the second step, the vegetables move to the right along with the screen 5. A limit bar 22 is installed on the right side of the frame 2 to act as a barrier, ensuring the vegetables fall evenly onto the slider 14 and preventing excessive drop at once. This also facilitates subsequent air separation. For vegetables of different varieties and sizes, the position of the limit bar 22 needs to be adjusted to ensure it is at the optimal barrier height, guaranteeing both even and even descent. A fixing block 34 is installed on the limit bar 22. Pulling the handle block 36 backward moves the fixed limit block 37, compressing the spring 35. At this point, the limit block 37 disengages from the fixed block. The locking mechanism of a set of limiting grooves 33 on the fixed plate 28 opens the limiting position, allowing the limiting strip 22 to move up and down to the desired position. Then, the spring force of the spring 35 drives the limiting block 37 to reset. At this time, the limiting strip 22 and the two fixed plates 28 are in a limited and fixed state. The two fixed plates 28 are fixed to the frame 2 by screws 32. After the two fixed plates 28 are removed, the screen 5 can also be opened and disassembled. The overall detachable design facilitates later cleaning and maintenance. The height of the limiting strip 22 is easy to adjust and can be quickly adjusted according to different vegetable sizes and screening requirements, improving the adaptability and flexibility of the equipment.
[0035] In the third step, the vegetables slide down slider 14 into the air separator 8 on the right. The servo motor 10 is activated, its output shaft driving the connecting shaft of the conveyor belt 9 to rotate, thus rotating the conveyor belt 9. The fan 6 is activated, and the airflow generated is transported to the air separator 8 through connecting pipe 2 18 and connecting pipe 1 13. The inner wall of the air separator 8 is protected by a protective net 16. The airflow generated by the fan 6 blows light impurities on the conveyor belt 9 into the collection box 11 through the conveying pipe 40, while heavier vegetables remain on the conveyor belt 9 and continue moving until they slide off slider 2 21 for collection. Impurities and substandard vegetables separated from the filter are collected and processed through the collection box 11. The screw 20 is rotated to move the baffle 19 attached to it. The baffle 19 is movably engaged in the connecting plate 15, while the servo motor 10 is rotated and connected to the connecting plate 15. As the baffle 19 moves downward, it blocks the protective net 16, thereby adjusting its air outlet area. Appropriate adjustment of the air outlet area can improve the efficiency of air separation, reduce the missed screening of light impurities and the mis-discharge of heavy materials. In addition, the entire screening process can be automated, reducing manual intervention and improving efficiency and safety.
