[0022] (III) Beneficial effects

[0023] The present invention provides a multifunctional pretreatment device for food detection. It has the following beneficial effects:

[0024] (1), For this multifunctional pretreatment device for food detection, when fruits are placed on the baffle, only by applying a certain pressure on the baffle can the baffle be pushed to rotate, and the fruits on the baffle can move to the arc-shaped scraper. The lifting device can push the annular frame downward, and through the one-way limit of the limit plate, the pushing block can push the fruits on the arc-shaped scraper to move. The arc-shaped scraper can scrape off part of the fruit peels, thus facilitating the detection of the peels.

[0025] (2) The multi-functional pretreatment device for food detection can drive the sunken plate to rotate by the rotation of the drive shaft. The rotation of the sunken plate and the baffle plate can drive the peels on the sunken plate to generate centrifugal force, so that the peels can always move at the position of the transverse cutting knife, so that the peels can fully contact the transverse cutting knife, thereby improving the crushing effect on the peels and enhancing the detection effect on the peels.

[0026] (3) The multi-functional pretreatment device for food detection can drive the arc-shaped block to rotate when the drive shaft rotates, so that the arc-shaped block can push the convex rod to move up and down through the elastic rod and the arc-shaped plate, so that the arc-shaped rod can drive the swing rod to swing up and down. The swing of the swing plate can push the peels adhered to and stuck on the arc-shaped sleeve frame and the arc-shaped scraping knife to move, preventing the peels from adhering to the arc-shaped sleeve frame and the arc-shaped scraping knife for a long time and deteriorating and rotting, which will affect the accuracy of food detection.

[0027] (4) After the fruit separates from the baffle plate, the multi-functional pretreatment device for food detection will move to the semi-circular plate and the inclined plate. The semi-circular plate and the inclined plate can limit the falling position of the fruit, so that the fruit can accurately move to the arc-shaped scraping knife. When the fruit is too large, the fruit will push the arc-shaped sleeve frame and the arc-shaped scraping knife to move through the semi-circular plate, the connecting rod and the Z-shaped plate, preventing the arc-shaped scraping knife from cutting off too much pulp from the fruit when the fruit is too large.

Detailed implementation manners

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figure 1-7 , the present invention provides a technical solution: a multifunctional pretreatment device 1 for food detection. A feeding frame 2 is fixedly installed at the top of the processing device 1, and the feeding frame 2 is communicated with the inside of the processing device 1. The processing device 1 includes:

[0038] A support frame 31, the support frame 31 is fixedly installed on one side of the processing device 1 close to the feeding frame 2. A lifting device 32 is fixedly installed at the bottom of the transverse position of the support frame 31. The lifting device 32 can be a hydraulic press or a device that can drive other devices to move up and down. An annular frame 33 is fixedly installed at the output end of the lifting device 32. The annular frame 33 is in contact with the inner wall of the feeding frame 2. A baffle 34 is hinged on the inner wall of the annular frame 33. A limiting plate 35 is fixedly installed on the inner wall of the annular frame 33. The limiting plate 35 is on the top of the baffle 34. A first elastic sheet is arranged between the limiting plate 35 and the baffle 34. The limiting plate 35 can limit the baffle 34, so that the limiting plate 35 can perform one-way limiting on the baffle 34, and the baffle 34 cannot rotate upward. A pushing block 36 is fixedly installed on the side of the baffle 34 away from the limiting plate 35;

[0039] The annular frame 37 is fixedly mounted on the inner wall of the processing device 1. An arc-shaped sleeve frame 38 is slidably mounted at the center of the annular frame 37. A second spring is arranged between the arc-shaped sleeve frame 38 and the annular frame 37. An arc-shaped scraper 39 is fixedly mounted on one end of the arc-shaped sleeve frame 38 close to the pushing block 36. The arc-shaped sleeve frame 38 and the arc-shaped scraper 39 are both provided with two pieces. When the fruit is placed on the baffle 34, the gravity of the fruit and the manual pressure of the person can push the baffle 34 to rotate downward. By rotating the baffle 34 downward, the baffle 34 will not be able to move the fruit. The fruit will move onto the arc scraper 39 through the gap formed by the rotation of the baffle 34. The lifting device 32 can push the annular frame 33, the baffle 34 and the pushing block 36 to move downward. The limiting plate 35 limits the baffle 34 so that the pushing block 36 can push the fruit on the arc scraper 39 to move downward. The arc scraper 39 can scrape off most of the peel of the fruit, so that the peel on the fruit can be collected, so that the pesticide residue on the peel can be detected, avoiding a large amount of pulp adhering to the peel that will affect the detection effect.

[0040] The processing device 1 is provided with a detection effect improving device, and the detection effect improving device comprises:

[0041] A collecting frame 51 is fixedly installed with the bottom of the inner wall of the processing device 1. A driving shaft 41 is rotatably installed at the bottom of the inner wall of the collecting frame 51. A recessed plate 52 is fixedly installed on the surface of the driving shaft 41. A blocking plate 53 is fixedly installed on the side of the recessed plate 52 close to the arc-shaped sleeve frame 38. A transverse crushing knife 54 is fixedly installed on the inner wall of the collecting frame 51. A guide plate 55 is fixedly installed on the inner wall of the processing device 1. The guide plate 55 can collect the scraped peels and enter the interior of the collecting frame 51. The driving shaft 41 can be driven to rotate by a driving device. The driving device can be a motor or a device that can drive the driving shaft 41 to rotate. The rotation of the driving shaft 41 can drive the recessed plate 52 to rotate. The rotation of the recessed plate 52 can drive the peel on the recessed plate 52 to rotate. When the blocking plate 53 on the recessed plate 52 rotates, the peel can rotate simultaneously with the recessed plate 52. When the peel rotates quickly, it will contact the horizontal crushing knife 54 on the collecting frame 51, and the peel can be crushed by the horizontal crushing knife 54. Due to the centrifugal force of the peel, the peel will be concentrated at the position of the horizontal crushing knife 54 and move, so that the peel can be crushed by the horizontal crushing knife 54. A discharge port is fixedly installed at the bottom of the collecting frame 51. When the rotation speed of the driving shaft 41 is reduced, the peel will be separated from the recessed plate 52 through the opening position in the middle of the recessed plate 52. The peel detection effect can be improved by crushing the peel.

[0042] The processing device 1 is provided with an auxiliary separation device, which comprises:

[0043] Convex rod 44 is slidably installed on the inner wall of the processing device 1. A third elastic sheet is provided between the convex rod 44 and the processing device 1. An arc rod 47 is fixedly installed on the side of the convex rod 44 close to the feeding frame 2. A swing rod 48 is hinged on the side of the arc rod 47 close to the arc sleeve frame 38. When the convex rod 44 moves, it will drive the arc rod 47. Through the arc rod 47, the swing rod 48 can be driven to swing. By the swing of the swing rod 48, the peel adhered to the arc scraper 39 and the arc sleeve frame 38 can be scraped off, avoiding deterioration due to long-term non-detachment, which will affect the detection effect;

[0044] Fixed disk 42 is fixedly installed on the driving shaft 41 close to the arc sleeve frame 38. An elastic rod 45 is fixedly installed on the side of the convex rod 44 close to the collection frame 51. An arc plate 46 is fixedly installed at the end of the elastic rod 45 away from the convex rod 44. An arc block 43 is fixedly installed on the side of the fixed disk 42 close to the arc plate 46. The arc block 43 contacts the arc plate 46. By rotating the fixed disk 42, the arc block 43 can be driven to rotate. When the arc block 43 rotates, it can push the elastic rod 45 to move up and down. Through the elastic rod 45, the convex rod 44 can be pushed to move, so that the swing rod 48 can avoid the peel from adhering to the arc scraper 39 and the arc sleeve frame 38.

[0045] A positioning feeding device is provided on the processing device 1. The positioning feeding device includes:

[0046] Elastic telescopic rod 61 is fixedly installed on the inner wall of the processing device 1. A semi-circular plate 62 is fixedly installed at the output end of the elastic telescopic rod 61. An inclined plate 63 is fixedly installed on the side of the semi-circular plate 62 close to the feeding frame 2. When the fruit is away from the baffle 34, the fruit will move onto the inclined plate 63 and the semi-circular plate 62. Through the inclined plate 63 and the semi-circular plate 62, the position of the fruit can be positioned, so as to ensure that the fruit can move onto the arc scraper 39, avoiding the fruit from not being able to move accurately onto the arc scraper 39 when it falls rapidly;

[0047] Connecting rod 64 is fixedly installed on the side of the semi-circular plate 62 close to the arc sleeve frame 38. A Z-shaped plate 65 is fixedly installed on the surface of the arc sleeve frame 38. The connecting rod 64 contacts the Z-shaped plate 65. When the semi-circular plate 62 moves a certain distance, the connecting rod 64 can drive the arc sleeve frame 38 to move away from each other through the Z-shaped plate 65, so that the arc sleeve frame 38 can drive the arc scraper 39 to move, thereby increasing the distance between the arc scrapers 39, avoiding scraping off too much pulp of the fruit when peeling a larger fruit, and thus avoiding too much pulp on the peel affecting the accuracy of contact;

[0048] The conveying pipe 67 penetrates through the flow guide plate 55, and the conveying pipe 67 is fixedly installed on the flow guide plate 55. A hemispherical frame 66 is fixedly installed at one end of the conveying pipe 67 close to the arc-shaped sleeve frame 38. A storage frame 68 is fixedly installed at the bottom of the inner wall of the processing device 1. The remaining pulp can be collected through the hemispherical frame 66 to prevent the pulp from being mixed with the peel.

[0049] During operation (or use), when it is necessary to detect the pesticide residues on the peel, the fruit to be detected is placed on the baffle 34 and rotated. Manually press the fruit to move downward. The gravity and pressing force of the fruit can push the baffle 34 to rotate downward. When the baffle 34 rotates downward, it can be heard that the pushing block 36 moves downward. Through the downward movement of the baffle 34 and the pushing block 36, the fruit can move to the inclined plate 63 and the semi-circular plate 62 through the gap between the baffle 34 and the pushing block 36. After the fruit separates from the baffle 34, the elastic force of the first elastic piece will drive the baffle 34 to rotate upward;

[0050] Start the lifting device 32. The lifting device 32 will drive the annular frame 33 to move downward. The downward movement of the annular frame 33 will drive the baffle 34, the limiting plate 35 and the pushing block 36 to move downward. When the pushing block 36 contacts the fruit, the fruit will push the baffle 34 and the pushing block 36 to rotate upward. Due to the rotation of the baffle 34 limited by the limiting plate 35, the baffle 34 cannot rotate upward at this time. Therefore, the baffle 34 and the pushing block 36 will push the fruit on the semi-circular plate 62 to move downward. When the fruit moves downward on the semi-circular plate 62, it can push the semi-circular plate 62 to move away from each other. When the semi-circular plate 62 moves, it can drive the connecting rod 64 to move. When the semi-circular plate 62 moves a certain distance, the connecting rod 64 can push the Z-shaped plate 65 to move. When the Z-shaped plate 65 moves, it can drive the arc-shaped sleeve frame 38 and the arc-shaped scraper 39 to move away from each other, thereby increasing the gap between the arc-shaped scrapers 39. While the fruit moves on the semi-circular plate 62, it will move onto the arc-shaped scraper 39. When the fruit moves downward on the arc-shaped scraper 39, the arc-shaped scraper 39 can cut off part of the peel of the fruit;

[0051] The cut-off peel will move onto the recessed plate 52 inside the collection box 51 through the diversion plate 55. Start the driving device, which will drive the driving shaft 41 to rotate. The rotation of the driving shaft 41 can drive the recessed plate 52 to rotate. The rotation of the recessed plate 52 can drive the blocking plate 53 to rotate. The rotation of the recessed plate 52 and the blocking plate 53 can drive the peel on the recessed plate 52 to rotate. The rotation of the peel will generate a centrifugal force that causes the peel to rotate closer to the transverse cutting knife 54. As the peel rotates at the position of the transverse cutting knife 54, the transverse cutting knife 54 can crush the peel on the recessed plate 52. When the rotation speed of the driving shaft 41 decreases, the centrifugal force of the peel decreases, causing the peel to move towards the smallest opening position of the recessed plate 52, and the peel will enter the inside of the collection box 51 and be discharged from the discharge port;

[0052] When the driving shaft 41 rotates, it can drive the fixed disk 42 to rotate. When the fixed disk 42 rotates, it will drive the arc-shaped block 43 to rotate. When the arc-shaped block 43 rotates, it will contact the arc-shaped plate 46. The contact between the arc-shaped block 43 and the arc-shaped plate 46 can push the arc-shaped plate 46 and the elastic rod 45 to move upward. The upward movement of the elastic rod 45 will drive the convex rod 44 and the arc-shaped rod 47 to move upward. When the arc-shaped block 43 disengages from the arc-shaped plate 46, under the elastic force of the third elastic piece, it will drive the convex rod 44 to move downward, so that the convex rod 44 can drive the arc-shaped rod 47 to move up and down. When the arc-shaped rod 47 moves up and down, it can drive the swing rod 48 to move up and down. The up and down movement of the swing rod 48 can push down the peel stuck or adhered to the arc-shaped sleeve frame 38 and the arc-shaped scraper 39, which can prevent the peel from not being able to enter the inside of the collection box 51.
