Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of agricultural product pesticide residue detection, and in particular to an agricultural product pesticide residue detection mechanism and a detection method. Background Art
[0002] The development of agricultural industrialization has made the production of agricultural products increasingly dependent on exogenous substances such as pesticides, antibiotics and hormones. The amount of pesticides used in agricultural products in my country remains high, and the irrational use of these substances will inevitably lead to excessive pesticide residues in agricultural products, affecting consumer food safety. In serious cases, it will cause consumers to become ill, develop abnormally, or even directly lead to poisoning and death. Excessive pesticide residues will also affect the trade of agricultural products. Countries around the world attach great importance to the problem of pesticide residues and have set increasingly stringent limit standards for pesticide residues in various agricultural and sideline products, making China's agricultural product exports face severe challenges.
[0003] At present, with the development of agricultural industrialization, the production of agricultural products is increasingly dependent on exogenous substances such as pesticides, antibiotics and hormones. The amount of pesticides used in food, vegetables, fruits and tea in my country remains high, and the irrational use of these substances will inevitably lead to excessive pesticide residues in agricultural products, affecting consumer food safety. In serious cases, it will cause consumers to become ill, develop abnormally, or even directly lead to poisoning. Therefore, when trading agricultural products, it is necessary to use testing equipment to test agricultural products for pesticide residues. However, it is difficult to test intact vegetables or fruits, and they need to be broken up and the juice tested during testing.
[0004] In the existing agricultural products, when testing for pesticide residues, the agricultural products need to be crushed to detect the residual juice therein. However, the existing crushing device cannot crush the agricultural products finely, resulting in low detection accuracy after the residual pesticide juice in the agricultural products is crushed and flows out during detection. In addition, when testing the crushing and filtering, the filtration is single and only filters through the filter in a static state, which can easily cause the filter to be blocked and affect the service life.

A mounting plate 53 is fixedly installed on one side surface of the crushing box 21, and the drive motor 51 is fixedly installed on the bottom of one end of the mounting plate 53.

Bearing seats 55 are fixedly installed on the top and bottom surfaces of one side of the storage frame 12.

[0044] The crushing mechanism 2 is provided to quickly crush the agricultural product to be tested so that the juice and residue flow out, and then enter the grinding mechanism 3 for grinding and centrifugal filtration, thereby controlling the detection liquid to enter the storage frame 12 for storage and waiting for detection, and the residual residue is left inside, which is convenient for later cleaning, and the grinding mechanism 3 can control the fine grinding of the agricultural product to be tested, so that the juice with residual pesticides in the agricultural product can flow out, thereby enhancing the accuracy of residual pesticide detection, and double centrifugal filtration can quickly separate the detection liquid and the residue, thereby enhancing the detection efficiency, and an independent power drive mechanism is used to control multiple devices to drive one power source, thereby saving costs and avoiding the cost increase of repair and replacement after damage caused by multiple power sources.
[0045] Working principle: Step 1: During operation, take the agricultural products to be tested and put them into the crushing mechanism 2, so that the agricultural products enter the crushing box 21 through the feed port 23 of the crushing box 21 and contact the crushing roller 22. The corresponding crushing shaft 24 is driven to rotate by the driving motor 51, thereby driving the corresponding first gear 25 to rotate. In the meshing state, multiple gears are controlled to rotate simultaneously, thereby driving multiple crushing rollers 22 to rotate, so as to perform preliminary crushing on the incoming products to be tested. After crushing, the products move downward under their own gravity and fall into the grinding mechanism 3.
[0046] Step 2: During grinding, the crushing shaft 24 is driven to rotate by the driving motor 51, and the first bevel gear 54 is driven to rotate, so that the rotation of the first bevel gear 54 drives the second bevel gear 56 to rotate, and then drives the power connection shaft 52 to rotate, thereby controlling the first pulley 57 at the bottom of the power connection shaft 52 to rotate. Under the condition of transmission by the belt 511, the second pulley 510 is controlled to rotate, and then the rotating shaft 59 is driven to rotate, thereby controlling the second gear 512 at the top of the rotating shaft 59 to rotate. Because the second gear 512 is engaged with the ring gear 513, the ring gear 513 is driven to rotate, driving the second discharge pipe 46 to rotate, and then controlling the rotation of the filter installation pipe 41 , thereby driving the grinding tube 31 to rotate. When the crushed agricultural products to be inspected fall into the interior of the hemispherical coarse filtering mesh tube 42, the hemispherical coarse filtering mesh tube 42 rotates to control the internal grinding hemisphere 32 to slide, squeeze and grind with the inner wall of the hemispherical coarse filtering mesh tube 42, and perform fine grinding. Therefore, the fine detection liquid after grinding is first roughly filtered through the hemispherical coarse filtering mesh tube 42 to enter the interior of the hemispherical fine filtering mesh tube 43, and then finely filtered through the hemispherical fine filtering mesh tube 43, so that the filtered detection liquid enters the interior of the storage frame 12 for storage and waiting for detection operation. When detection is required, it is only necessary to open the first valve 14 to control the fine detection liquid to flow out for detection;
[0047] Step 3, when there is residue after grinding, the second valve 45 and the third valve 47 are opened to control the discharge of the residue. After the operation is completed, the cleaning water is controlled to be poured into the crushing box 21, and the residual residue and the residual liquid left inside are cleaned under the condition of the rotation of the filter installation tube 41. After cleaning, wait for the next use.

10. A detection method for agricultural product pesticide residue detection according to any one of claims 1 to 9, characterized in that: Step 1: During the operation, the agricultural products to be inspected are taken and placed in the crushing mechanism (2), so that the agricultural products enter the crushing box (21) through the feed port (23) of the crushing box (21) and come into contact with the crushing roller (22). The corresponding crushing shaft (24) is driven to rotate by the driving motor (51), thereby driving the corresponding first gear (25) to rotate. In the meshing state, multiple gears are controlled to rotate simultaneously, thereby driving multiple crushing rollers (22) to rotate, thereby performing preliminary crushing on the entered products to be inspected. After crushing, the products move downward under their own gravity and fall into the grinding mechanism (3); Step 2: During grinding, the crushing shaft (24) is driven to rotate by the driving motor (51), while driving the first bevel gear (54) to rotate, so that the rotation of the first bevel gear (54) drives the second bevel gear (56) to rotate, and then drives the power connection shaft (52) to rotate, thereby controlling the first pulley (57) at the bottom end of the power connection shaft (52) to rotate, and under the condition of belt (511) transmission, the second pulley (510) is controlled to rotate, thereby driving the rotation of the rotating shaft (59), thereby controlling the rotation of the second gear (512) at the top of the rotating shaft (59), because the second gear (512) is meshed with the gear ring (513), thereby driving the gear ring (513) to rotate, driving the second discharge pipe (46) to rotate, and then controlling the filtering device The mounting tube (41) rotates, thereby driving the grinding tube (31) to rotate. When the crushed agricultural products to be inspected fall into the interior of the hemispherical coarse filtering mesh tube (42), the hemispherical coarse filtering mesh tube (42) controls the internal grinding hemisphere (32) to slide, squeeze and grind with the inner wall of the hemispherical coarse filtering mesh tube (42) due to the rotation of the hemispherical coarse filtering mesh tube (42), thereby performing fine grinding. Thus, the fine testing liquid after grinding is first roughly filtered through the hemispherical coarse filtering mesh tube (42) and enters the interior of the hemispherical fine filtering mesh tube (43). The fine filtering is then performed through the hemispherical fine filtering mesh tube (43), and the filtered testing liquid enters the interior of the storage frame (12) for storage and waiting for the testing operation. When testing is required, it is only necessary to open the first valve (14) to control the fine testing liquid to flow out for testing. Step 3: When the residue after grinding is released, the second valve (45) and the third valve (47) are opened to control the discharge of the residue. After the operation is completed, the cleaning water is controlled to be poured into the crushing box (21) to clean the residue and the residual liquid left inside under the condition that the filter installation pipe (41) rotates. After cleaning, wait for the next use.
