Abstract
Description
Technical Field
[0001] This utility model relates to the field of food safety inspection technology, specifically to a rapid detection and sterilization device for pesticide residues in blueberries. Background Technology
[0002] Fruits are juicy, edible plant fruits with a predominantly sweet and sour taste. Fruits are not only rich in nutrients but also promote digestion. Blueberries, also known as bilberries, belong to the genus *Vaccinium* of the Ericaceae family. Before processing or harvesting, they require pesticide residue testing.
[0003] According to a publicized rapid detection device for pesticide residues in fruits (publication number: CN215811943U), the above application uses a stirring and liquid extraction mechanism. After the fruit peel slides down the surface of the fixed block and falls into the soaking tank, the telescopic motor is activated to raise the soaking tank, the stepper motor is activated to rotate the moving rod to stir, and the liquid extraction pump is activated to draw the soaking liquid at the bottom of the soaking tank into the connecting pipe and then into the measuring cylinder. This allows for uniform stirring of the fruit peel and the soaking liquid, saving workers' time and ensuring the stirring efficiency of the fruit peel.
[0004] However, in the aforementioned application, the porous filter screen is designed so that the fruit peel can only remain on the upper layer of the screen, achieving solid-liquid separation. However, in the aforementioned application, the porous filter screen will become clogged after prolonged use, making it difficult for the juice from the fruit peel and pulp to pass through the filter screen into the immersion tank of the application. Personnel need to remove and clean the filter screen before it can be reused, which is time-consuming, labor-intensive, and delays the testing efficiency. Utility Model Content

[0024] like Figures 1-6As shown, this utility model provides a technical solution: a rapid detection and sterilization device for pesticide residues in blueberries, including a box body 1, with a feed inlet 2 on the surface of the box body 1, and a crushing component 7 for chopping and filtering blueberries on the surface of the box body 1. The crushing component 7 includes: an L-shaped plate 70, a motor 71, a rotating rod 72, a cutting blade 73, a gear 74, a filter plate 75, and a concave frame 76. A clearing component 8 for clearing the filter plate 75 is provided on the surface and inside of the box body 1. The clearing component 8 includes: a first pulley 80, which is penetrated by the output shaft of the motor 71 and is fixedly connected to the output shaft of the motor 71; a short rod 82 is provided on the surface of the box body 1, which penetrates the box body 1 and is rotatably connected to the box body 1; a second pulley 81 is passed through the short rod 82 and is fixedly connected to the second pulley 81; the clearing component 8 also includes a half gear 83, which is rotatably connected to the inner wall of the box body 1. The surface of the gear 82 is fixedly connected to the surface of the half gear 83. A spiral rod 84 is slidably connected to the inner wall of the housing 1. A locking tooth 85 is fixed to the inner side of the spiral rod 84. The half gear 83 meshes with the locking tooth 85. A sliding plate 86 is fixed to the top of the spiral rod 84. A top rod 88 is fixed to the top of the sliding plate 86. A drain hole 87 is opened on the surface of the sliding plate 86. A belt is connected to the surfaces of the first pulley 80 and the second pulley 81. Two sets of locking teeth 85 are provided, and both sets of locking teeth 85 are connected to the spiral rod 84. The center line is symmetrically set with the axis of symmetry. The top rod 88 corresponds to the hole of the filter plate 75. When the motor 71 starts, the pulley 1 80 drives the pulley 2 81, the short rod 82 and the half gear 83 to rotate through the belt. When the half gear 83 meshes with a set of locking teeth 85, the return rod 84 drives the slide plate 86 and the top rod 88 to move upward. The top rod 88 enters the hole of the filter plate 75 and pushes out the fruit peel and pulp stuck in the hole. It can be cleared without personnel removal, which improves the efficiency of subsequent testing.
[0025] L-shaped plate 70 is fixed to the surface of box 1. Motor 71 is fixed to the surface of L-shaped plate 70. Gear 74 is rotatably connected to the surface of box 1. Rotating rod 72 is rotatably connected to the inner wall of box 1. One end of rotating rod 72 away from the inner wall of box 1 passes through box 1, and the other end of rotating rod 72 passes through gear 74. Rotating rod 72 and gear 74 are fixedly connected. There are three sets of gears 74 and rotating rod 72. The three sets of gears 74 and rotating rod 72 are linearly arrayed on the surface and inside of box 1. The output shaft of motor 71 is fixed to the surface of one of the three sets of gears 74. Cutting blade 73 is fixed to the surface of rotating rod 72. Concave frame 76 is fixed to the inner wall of box 1. Filter plate 75 is inserted into the inner side of concave frame 76. The three sets of gears 74 mesh in sequence. When motor 71 is turned on, it drives gear 74 to rotate. At this time, the three sets of gears 74 drive rotating rod 72 and cutting blade 73 to cut and crush blueberries, while making the soaking liquid and blueberries fully mixed.
[0026] The surface of the feed inlet 2 is equipped with a sealing door 3, and the left side surface of the box body 1 is equipped with a liquid outlet 5. A solenoid valve 6 is connected between the liquid outlet 5 and the box body 1. The sealing door 3 can prevent external impurities from entering. Opening the solenoid valve 6 allows the soaking solution to be discharged through the liquid outlet 5. Personnel can conduct tests using test strips or pesticide residue testing instruments, which is convenient for testing.
[0027] When blueberries need to be tested for pesticide residues, the sealed door 3 is opened, and the blueberries are fed into the chamber 1 through the feed inlet 2. At this time, the motor 71 is turned on, driving the gears 74 to rotate. The three sets of gears 74 drive the rotating rod 72 and the cutting blade 73 to cut and crush the blueberries. At the same time, the ultraviolet sterilization lamp 4 is turned on to sterilize the blueberries, reducing or eliminating microbial contamination in the sample to ensure the accuracy and reliability of the test results. Meanwhile, the soaking solution is injected through the feed inlet 2, and the sealed door 3 is closed. The continuous operation of the rotating rod 72 and the cutting blade 73 also allows the soaking solution to be fully stirred and mixed with the blueberries. The pulp stays above the filter plate 75. At the same time, when the motor 71 starts, it drives the pulley 1 80 to rotate. Through the belt, it drives the pulley 2 81, the short rod 82, and the half gear 83 to rotate. When the half gear 83 meshes with a set of cleats 85, the return rod 84 drives the slide plate 86 and the top rod. The upward movement of 88 allows the push rod 88 to enter the gaps of the filter plate 75, thereby pushing out the fruit peel and pulp stuck in the gaps. This allows for unblocking without the need for manual removal, improving subsequent testing efficiency. When the half gear 83 meshes with another set of retaining teeth 85, it drives the return rod 84, slide plate 86, and push rod 88 downward, causing the push rod 88 to disengage from the gaps of the filter plate 75. While the motor 71 is continuously working, the push rod 88 can reciprocate into the gaps of the filter plate 75, improving unblocking efficiency. The drainage hole 87 does not affect the flow of soaking liquid and juice. Personnel can control the opening of the solenoid valve 6 to allow the soaking liquid to be discharged through the outlet 5. Personnel can then conduct tests using test strips or pesticide residue testing instruments, facilitating testing. Additionally, if too many blueberries remain on the surface of the filter plate 75, the filter plate 75 can be removed for cleaning. During installation, the filter plate 75 is inserted into the concave frame 76 for stable positioning, making operation convenient.
[0028] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
