Description

Technical Field

[0001] This utility model relates to the field of rapeseed cleaning technology, specifically to a rapeseed cleaning device. Background Technology

[0002] Rapeseed is one of the most widely cultivated oilseed crops in the country, and its seeds are an important source of edible oil and many industrial raw materials. In my country, rapeseed is widely planted, and with the continuous development of the agricultural industry, rapeseed production has shown a steady upward trend. High-quality rapeseed plays a crucial role in ensuring the quality of edible oil and meeting the processing needs of related industries.

[0003] However, during the rapeseed harvesting process, various impurities are often mixed in, such as soil, sand, straw fragments, shriveled seeds, and seeds from other crops. If these impurities are not effectively removed, they will have many adverse effects. In the rapeseed oil extraction process, the presence of impurities may lead to accelerated wear and tear on the oil extraction equipment, reducing its service life. It will also affect the oil extraction rate and the purity of the oil, resulting in a decline in the quality of the produced edible oil, failing to meet the high standards required by the market.

[0004] In view of this, we propose a rapeseed cleaning device. Utility Model Content

[0005] The purpose of this invention is to provide a rapeseed cleaning device that solves the problem of insufficient oil purity caused by impurities.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A rapeseed cleaning device includes a frame with a first screen and a second screen disposed inside the frame; it also includes a cleaning assembly for cleaning rapeseed; and a vibration assembly for vibrating the first screen and the second screen. The cleaning assembly includes a feed hopper fixedly installed in the upper frame of the frame, a panel fixedly installed on the surface of the frame, a receiving box fixedly installed on the right side of the frame, an adjusting plate slidably connected inside the receiving box, a blower fixedly installed on the top of the receiving box, the air inlet of the blower connected to an opening at the top of the receiving box, a separating plate fixedly installed inside the frame, and a baffle fixedly installed on the outer side of the separating plate.

[0008] Preferably, the panel surface has a slag outlet, the receiving box surface has a groove, the receiving box has a discharge port on the outside, the receiving box has an inclined plate fixedly installed inside, the inclined plate is connected to the discharge port, and the frame has a guide plate fixedly installed inside.

[0009] Preferably, the vibration assembly includes: a motor, the motor being fixedly mounted on the surface of the frame, and a cam being fixedly mounted on the surface of the motor output shaft.

[0010] Preferably, a connecting plate is fixedly installed on the surface of the motor output shaft, the connecting plate is fixedly installed inside the frame, a buffer spring one is fixedly installed on one end of the inner side of the connecting plate, and a buffer spring two is fixedly installed on the other end of the inner side of the connecting plate.

[0011] Preferably, one end of the first screen is rotatably connected to the inside of the frame, and the other end of the first screen is fixedly installed at the bottom of the buffer spring.

[0012] Preferably, one end of the second screen is rotatably connected to the inside of the frame, and the other end of the second screen is fixedly installed on the top of the second buffer spring.

[0013] Preferably, the connecting plate has a U-shaped cross-section, and there are two cams, both of which are symmetrically arranged with the center line of the motor output shaft as the axis of symmetry.

[0014] By employing the above technical solution, this utility model provides a rapeseed cleaning device. It possesses at least the following beneficial effects:

[0015] (1) Through the setting of the cleaning component, the rapeseed enters the device from the feed hopper and is first screened through the first screen and the second screen to separate impurities and seeds of different particle sizes. The separated small dust particles are discharged through the guide plate. The seeds are guided into the receiving box by the inclined plate and further removed by the wind cleaning in the receiving box. Finally, the rapeseed is graded and purified, which prevents the rapeseed from being ineffective in removing impurities, improves the thoroughness of rapeseed impurity removal, and enhances the purity of rapeseed. The rapeseed collected in the end has fewer impurities and higher quality.

[0016] (2) By setting up the vibration component, the starting motor drives the cam to rotate through the output shaft. When the cam rotates, it vibrates inside the first and second screens, causing the first and second screens to swing towards the inner wall of the connecting plate. When the first and second screens swing, they are damped and reset by buffer spring one and buffer spring two, ensuring that the screen vibration frequency is stable and avoiding the weakening of vibration amplitude due to external force attenuation, thus maintaining continuous screening efficiency. When the cam rotates and vibrates the screen, the first and second screens swing back and forth under the cooperation of buffer spring one and buffer spring two, forming high-frequency vibration. This vibration can promote the rapeseed to be evenly dispersed and rolled on the screen, so that seeds and impurities of different sizes can be separated more efficiently through the screen holes, preventing the screen holes from being blocked and affecting the cleaning, thus improving the screening accuracy.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0027] A rapeseed cleaning device, such as Figures 1-4 As shown, it includes a frame 1, and a first screen 2 and a second screen 3 are provided on the inner side of the frame 1;

[0028] It also includes cleaning component 4, used for cleaning rapeseed;

[0029] Vibration component 6 is used to vibrate the first screen 2 and the second screen 3;

[0030] First, the cleaning component 4 includes: a feed hopper 41, which is fixedly installed in the upper frame of the frame 1; a panel 44 is fixedly installed on the surface of the frame 1; a receiving box 45 is fixedly installed on the right side of the frame 1; an adjusting plate 46 is slidably connected inside the receiving box 45; a blower 47 is fixedly installed on the top of the receiving box 45; the air intake of the blower 47 is connected to the opening at the top of the receiving box 45; a distribution plate 48 is fixedly installed inside the frame 1; and a distribution plate 48 is fixedly installed on the outside of the distribution plate 48. The baffle 49 can improve the stability of rapeseed separation by being installed on the outside of the separating plate 48. The panel 44 has a slag outlet 440 on its surface, the receiving box 45 has a groove 450 on its surface, the receiving box 45 has a discharge port 451 on its outside, the receiving box 45 has an inclined plate 411 fixedly installed inside the receiving box 45, the inclined plate 411 is connected to the discharge port 451, and the frame 1 has a guide plate 412 fixedly installed inside the frame 1.

[0031] In this embodiment, through the setting of the cleaning component 4, rapeseed enters the device from the feed hopper 41 and is first screened on the first screen 2 and the second screen 3 to separate impurities and seeds of different particle sizes. The separated small dust particles are discharged through the guide plate 412. The seeds are guided into the receiving box 45 by the inclined plate 411, and the light impurities are further removed by the wind cleaning in the receiving box 45. Finally, the rapeseed is graded and purified, which prevents the rapeseed from being ineffective in removing impurities, improves the thoroughness of rapeseed impurity removal, and enhances the purity of rapeseed. This results in rapeseed with fewer impurities and higher quality that is finally collected. Example

[0032] like Figures 5-7 As shown, the vibration assembly 6 includes: a motor 61, which is fixedly mounted on the surface of the frame 1, and a cam 62 is fixedly mounted on the surface of the output shaft of the motor 61.

[0033] Secondly, a connecting plate 63 is fixedly installed on the surface of the output shaft of the motor 61. The connecting plate 63 is fixedly installed inside the frame 1. A buffer spring 64 is fixedly installed on one end of the inner side of the connecting plate 63, and a buffer spring 65 is fixedly installed on the other end of the inner side of the connecting plate 63. One end of the first screen 2 is rotatably connected to the inside of the frame 1, and the other end of the first screen 2 is fixedly installed at the bottom of the buffer spring 64. One end of the second screen 3 is rotatably connected to the inside of the frame 1, and the other end of the second screen 3 is fixedly installed at the top of the buffer spring 65.

[0034] The connecting plate 63 has a U-shaped cross section and two cams 62. Both cams 62 are symmetrically arranged with the center line of the output shaft of the motor 61 as the axis of symmetry. The U-shaped connecting plate 63 can improve the connection effect between the connecting plate 63 and the first screen 2 and the second screen 3.

[0035] In this embodiment, the vibration component 6 enables the motor 61 to drive the cam 62 to rotate via the output shaft. When the cam 62 rotates, it vibrates the inner side of the first screen 2 and the second screen 3, causing the first screen 2 and the second screen 3 to swing towards the inner wall of the connecting plate 63. When the first screen 2 and the second screen 3 swing, they are damped and reset by the buffer spring 64 and the buffer spring 65, ensuring that the screen vibration frequency is stable and avoiding the weakening of vibration amplitude due to external force attenuation, thus maintaining continuous screening efficiency. When the cam 62 rotates and vibrates the screen, the first screen 2 and the second screen 3 swing back and forth under the cooperation of the buffer spring 64 and the buffer spring 65, forming high-frequency vibration. This vibration can promote the rapeseed to be evenly dispersed and rolled on the screen, so that the seeds and impurities of different sizes can be separated more efficiently through the screen holes, preventing the screen holes from being blocked and affecting the cleaning, thus improving the screening accuracy.

[0036] In use, the rapeseed cleaning device of this utility model allows rapeseed to enter the device from the feed hopper 41 and first pass through the first screen 2, which is a coarse screen with large mesh openings to separate large particles of impurities. These large particles, such as pebbles, will gradually move to the right due to the shaking of the first screen 2 and be discharged from the slag outlet 440 of the panel 44 via the separating plate 48 and baffle 49. The separated rapeseed will fall onto the second screen 3, which is a fine screen with smaller mesh openings to further separate the rapeseed under the first screen 2. The separated small particles of dust will be discharged through the guide plate 412. The seeds, also gradually moving to the right due to the shaking of the second screen 3, will be guided into the receiving box 45 by the inclined plate 411 and cleaned by the airflow within the receiving box 45. Further removal of light impurities is achieved to ultimately grade and purify the rapeseed. The rapeseed falls to the bottom of the frame 1 for collection, and the pure rapeseed enters the receiving box 45. To ensure stable operation of the equipment, the regulating plate 46 can control the intensity of the air cleaning. After the blower 47 at the bottom of the receiving box 45 is started, the air inlet draws in air from the top opening, forming an airflow from bottom to top. During the fall of the rapeseed, light impurities are carried up by the airflow and discharged through the top of the receiving box 45; the heavier rapeseed slides down the inclined plate 411 to the discharge port 451 for collection. The inclined angle design of the inclined plate 411 can prolong the residence time of the rapeseed in the box, enhance the air separation effect, prevent poor effect in removing impurities from the rapeseed, improve the thoroughness of impurity removal from the rapeseed, and improve the purity of the rapeseed; so that the rapeseed collected in the end has fewer impurities and higher quality.

[0037] When rapeseed is screened, motor 61 is started to drive cam 62 to rotate via output shaft. When cam 62 rotates, it vibrates the inner side of the first screen 2 and the second screen 3, causing the first screen 2 and the second screen 3 to swing towards the inner wall of connecting plate 63. When the first screen 2 and the second screen 3 swing, they are damped and reset by buffer spring 1 64 and buffer spring 2 65. After the screen swings, the buffer springs quickly reset the screen by their elasticity, ensuring that the screen vibration frequency is stable and avoiding the weakening of vibration amplitude due to external force attenuation, thus maintaining continuous screening efficiency. When cam 62 rotates and vibrates the screen, the first screen 2 and the second screen 3 swing back and forth under the cooperation of buffer spring 1 64 and buffer spring 2 65, forming high-frequency vibration. This vibration can promote the rapeseed to be evenly dispersed and rolled on the screen, so that seeds of different sizes and impurities can be separated more efficiently through the screen holes. In particular, it has a breaking effect on wet or sticky rapeseed, preventing the screen holes from clogging and affecting the cleaning efficiency, thus improving the screening accuracy.
