Abstract
Description
Technical Field
[0001] The utility model belongs to the field of pesticide residue detection, and more specifically, particularly relates to a pesticide residue detection and extraction device. Background Art
[0002] Pesticide residue testing is a testing process used to determine the concentration of pesticides in food. Pesticide residue testing usually involves the analysis of pesticide residues in crops, fruits and other foods to determine whether the pesticide residues in food meet national food safety standards. At present, the pesticide residue testing process includes sampling, extraction and purification. The extraction work usually requires the tested fruit crops to be crushed to form a homogenate and then injected into a chemical extract for mixing. However, in the traditional pesticide residue detection and extraction work, the fruit crops need to be manually knocked and crushed, and then the homogenate is poured into a mixing bottle for manual shaking. It can be seen that both the fruit crushing and the mixing of the extract and the homogenate require manual operation. The knocking and crushing process of the fruit crops is not only time-consuming and laborious, but also the manual shaking frequency of the mixing bottle is difficult to grasp, and the extract and the homogenate cannot be fully mixed, resulting in low extraction efficiency.

[0024] When the utility model is performing the pesticide detection and extraction work, the fruit and vegetable particles to be detected are first poured into the crushing storage barrel 21, and the fruit and vegetable particles fall on the upper side of the discharge plate 25, and then the two groups of clamping plate frames 14 are turned over and closed, and the mixing bottle 12 is placed between the two groups of clamping plate frames 14, and then the clamping bolts 17 are inserted into the through holes of the left clamping plate frame 14 and screwed into the threaded through holes of the right clamping plate frame 14, so as to complete the clamping work of the mixing bottle 12 between the two groups of clamping plate frames 14, and then the programmable controller 22 controls the adjustment motor 6 to rotate, and the adjustment motor 6 drives the threaded rod 2 to rotate. The threaded rod 2 is meshed and connected in the threaded through hole of the sliding plate 1, and the threaded rod 2 drives the sliding plate 1 to move downward along the through groove of the support frame 3 until the baffle plate 23 penetrates into the crushing storage barrel 21. At this time, the discharge plate 25 and the baffle plate 23 are located at the inner side of the crushing storage barrel 21 at the same time, forming a structure in which the crushing storage barrel 21 is closed up and down to prevent fruit and vegetable juice from splashing during the chopping process of fruit and vegetable particles.

The sliding plate 1 drives the rotating rod 20 at the bottom of the transmission disk 27 to move downward, and the rotating rod 20 drives the edge of the discharge plate 25 to break away from the bottom opening of the crushing storage barrel 21. The homogenate in the crushing storage barrel 21 falls into the discharge barrel 11, and then falls into the mixing bottle 12 through the shrinkage at the bottom of the discharge barrel 11. At this time, the sliding plate 1 continues to move downward, and the pressure rod 8 welded to the lower side of the sliding plate 1 pushes the piston rod 10 to move downward inside the liquid storage barrel 9, and the liquid storage The chemical extract in the cylinder 9 is squeezed into the infusion hose 18 by the piston rod 10, and then the chemical extract is transported to the dropper 19 by the infusion hose 18, and finally dripped into the mixing bottle 12 by the dropper 19. The programmable controller 22 controls the shaking motor 7 to drive the turntable 16 to rotate, and the convex column on the front side of the turntable 16 rotates around the central axis of the turntable 16. At this time, the convex column of the turntable 16 slides in the long through groove of the follower plate 15, so that the turntable 16 pushes the follower plate 15 to swing left and right, and the follower plate 15 drives the mixing bottle 12 clamped by the two sets of clamping plate frames 14 to shake left and right, completing the automatic shaking and mixing work of the homogenate and the mixed liquid in the mixing bottle 12.
[0025] In the embodiment of the present disclosure, the left and right sides of the sliding plate 1 are provided with grooves that pass through from top to bottom. The portion between the two groups of grooves of the sliding plate 1 is embedded in the through groove of the support frame 3. The upper side of the sliding plate 1 is provided with a threaded through hole. The threaded rod 2 is meshed and connected in the threaded through hole of the sliding plate 1. The threaded rod 2 can drive the sliding plate 1 to move vertically up and down along the through groove of the support frame 3. The support frame 3 pushes the unloading plate 25 to slide along the inside of the crushing storage barrel 21, thereby completing the closed crushing and open unloading work of the crushing storage barrel 21.
[0026] In the disclosed embodiment, the liquid storage cylinder 9 is a cylindrical structure with an opening on the upper side. The inner side of the liquid storage cylinder 9 is filled with extraction liquid. The piston rod 10 is inserted into the interior of the liquid storage cylinder 9 from the opening on the upper side of the liquid storage cylinder 9. The outer side of the piston rod 10 is tightly fitted to the inner side of the liquid storage cylinder 9. The piston rod 10 and the pressure rod 8 are opposite to each other up and down. The pressure rod 8 pushes the injection mechanism composed of the piston rod 10 and the liquid storage cylinder 9 to complete the automatic injection of the extraction liquid into the mixing bottle 12.
[0027] In the disclosed embodiment, the discharge barrel 11 is a cylindrical structure that penetrates from top to bottom, and the bottom end of the barrel 11 is a necked structure. The necking at the bottom of the discharge barrel 11 is opposite to the top feed port of the mixing bottle 12, and the diameter of the necking at the bottom of the discharge barrel 11 is smaller than the top feed port of the mixing bottle 12, so that the crushed fruit and vegetable slurry can flow accurately into the interior of the mixing bottle 12 to prevent the fruit and vegetable slurry from leaking out.
[0028] In the disclosed embodiment, a long through groove is provided on the follower plate 15, and the convex column on the front side of the turntable 16 is inserted into the long through groove of the follower plate 15. When the turntable 16 rotates, the convex column of the turntable 16 slides along the long through groove of the follower plate 15 so that the convex column of the turntable 16 pushes the follower plate 15 to swing left and right, thereby completing the automatic shaking of the mixing bottle 12.
[0029] In the disclosed embodiment, there are two groups of clamping frames 14, and the clamping frames 14 are symmetrically distributed on the left and right. A through hole is provided on the left clamping frame 14, and a clamping bolt 17 is inserted into the through hole of the left clamping frame 14. A threaded through hole is provided on the right clamping frame 14, and the outer side surface of the clamping bolt 17 is threadedly engaged and connected in the threaded through hole of the clamping frame 14, so that the two groups of clamping frames 14 are closed and fixed in opposite directions, and the two groups of clamping frames 14 complete the clamping work of the mixing bottle 12. An arc-shaped groove is provided on each group of clamping frames 14, and a rubber gasket is provided on the inner side of the arc-shaped groove. The rubber gasket inside the clamping frame 14 increases the contact friction between the clamping frame 14 and the mixing bottle 12, so that the two groups of clamping frames 14 can stably clamp the mixing bottle 12 to prevent the mixing bottle 12 from being thrown out during the left and right shaking process.
[0030] The installation, connection or setting methods of all the above components are common mechanical methods, such as welding, threaded connection, screw connection, etc., and the specific structures, models and coefficient indicators of all its components are its own technology, as long as it can achieve its beneficial effects, it can be implemented. The above-mentioned crushing motor 4, regulating motor 6, swinging motor 7, and programmable controller 22 are all common components on the market. When you buy them back and use them, you only need to connect them according to the instruction manual purchased together, so I will not repeat them here.
