Description

Technical Field

[0001] The invention relates to the technical field of vegetable detection and crushing processing, and in particular to a vegetable residual pesticide detection pre-processing device. Background Art

[0002] The development of vegetable industrialization has made the production of agricultural products increasingly dependent on exogenous substances such as pesticides, antibiotics and hormones. The irrational use of these substances will inevitably lead to excessive pesticide residues in agricultural products, affecting consumers' food safety. In severe 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 stipulated increasingly stringent limit standards for pesticide residues in various agricultural and sideline products, posing severe challenges to the export of agricultural products.

[0003] Before testing for pesticide residues in vegetables, the vegetables to be tested are generally crushed (tissue crushing) and then the liquid produced by crushing is extracted for testing for pesticide residues. However, the existing crushing treatment devices used before testing for pesticide residues in vegetables generally use a stirring device in conjunction with a cutting knife for stirring and crushing. The contact area between stirring and cutting is relatively small, and the crushing efficiency is poor.

[0004] To this end, we propose a pretreatment device for detecting pesticide residues in vegetables. Summary of the invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The vegetables to be inspected are put into the processing pipeline. The vegetables enter the crushing gear. The motor drives the first shaft to rotate at the original position.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Embodiment 1

[0036] Please refer to Figure 1-Figure 12 , a pre-treatment device for detecting residual pesticides in vegetables, comprising a treatment table 1, the treatment table 1 is connected to a treatment pipeline 2, two movable plates 3 are arranged in the treatment pipeline 2, a rotating groove 4 is opened on the movable plate 3, a rolling gear 5 is rotatably connected in the rotating groove 4, the two rolling gears 5 are meshed with each other, the edges of the two rolling gears 5 are respectively fixedly connected with a first rotating shaft 6 and a second rotating shaft 7, a sleeve 8 is fixedly connected to the inner wall of the treatment pipeline 2, a sleeve rod 9 rotatably connected to the second rotating shaft 7 is movably sleeved in the sleeve 8, and a matching wheel 10 is arranged below the meshing point of the two rolling gears 5; a movable component, the movable component makes the crushed vegetables accumulate by the two rolling gears 5 that make circular motion and cooperate with the sleeve rod 9, so as to facilitate multiple crushing of the rolling gears 5; a matching component, the matching component is used to make the matching wheel 10 tightly press against the rolling gear 5; an adsorption component, the adsorption component is used to re-convey the vegetables located at the bottom of the treatment pipeline 2 into the meshing point above the two rolling gears 5.

[0037] The movable component includes a pressure plate 11 connected to both ends of the sleeve rod 9, the pressure plate 11 moves in the processing pipe 2, and a wedge block 12 that slides with the inner wall of the processing pipe 2 is fixedly connected to the bottom of the pressure plate 11. A motor 13 is fixedly connected to the outer surface of the processing pipe 2, and the output shaft of the motor 13 penetrates into the processing pipe 2 and is connected and fixed to the first rotating shaft 6.

[0038] A pressure plate 14 is fixedly connected to the bottom of the movable plate 3, and a plurality of distribution plates 15 are fixedly connected to the bottom of the sleeve rod 9, so as to make the top surface of the vegetables at the bottom of the processing pipe 2 uniform and avoid bulges, thereby ensuring the function of the pressure plate 14 and the rolling gear 5. A delivery hole 16 is opened on the processing pipe 2, and a cover plate is placed on the delivery hole 16.

[0039] The mating component includes a movable frame 17 connected and fixed to the movable plate 3. The rotating shaft of the mating wheel 10 moves in the movable frame 17. A pressing arc plate 18 is pressed and fitted under the rotating shaft of the mating wheel 10. A compression spring 19 is hung and fitted between the pressing arc plate 18 and the movable frame 17.

[0040] The adsorption assembly includes an adsorption tube 20, one end of which penetrates into the processing table 1 and is connected to the bottom of the processing pipe 2, and the other end of the adsorption tube 20 is connected to the top of the processing pipe 2. A negative pressure suction device is provided on the top of the adsorption tube 20, and an anti-adhesion layer is provided on the inner wall of the adsorption tube 20 to prevent vegetables from accumulating on the inner wall of the adsorption tube 20, which helps the negative pressure adsorption device (the negative pressure adsorption device is a conventional technology and is not described in detail in this scheme) to re-crush the vegetables.

[0041] One end of the adsorption tube 20 is an inclined section, a connecting hole 21 is opened on the inclined section of the adsorption tube 20, a collecting box corresponding to the position of the connecting hole 21 is arranged inside the processing station 1, and a baffle 22 with a high density is hinged on the outer surface of the adsorption tube 20.

[0042] In this embodiment, the vegetables to be tested are put into the processing pipe 2 through the putting hole 16, and the vegetables enter the rolling gear 5. The motor 13 drives the first rotating shaft 6 to rotate at the original position, and one of the corresponding rolling gears 5 rotates, and the two rolling gears 5 are always meshed, so that the two rolling gears 5 rotate, and the first rotating shaft 6 and the second rotating shaft 7 are respectively located at the edges of the two rolling gears 5, so that the two rolling gears 5 rotate while performing circular motion, and the second rotating shaft 7 is located at the edge of the rolling gear 5. When the second rotating shaft 7 rotates, it drives the sleeve rod 9 to perform adaptive reciprocating motion along the sleeve 8 at the fixed position;

[0043] Under the rolling action of the two rolling gears 5, the vegetables enter the meshing position of the two rolling gears 5, thereby squeezing and crushing the vegetables and separating them into vegetable residue and vegetable juice. Under the action of the compression spring 19, the pressing arc plate 18 acts on the rotating shaft of the matching wheel 10, so that the matching wheel 10 is always tightly pressed against the rotating rolling gear 5. The vegetable residue is pressed upward by the matching wheel 10, ensuring that the vegetables are fully crushed.

[0044] It is worth noting that: there is no gap at the connection between the movable frame 17 and the movable plate 3, the end surface of the matching wheel 10 and the movable frame 17 are kept in close contact, and the top and bottom of the movable frame 17 are always located within the end surface of the matching wheel 10 and will not exceed the end surface of the movable matching wheel 10, thereby preventing vegetables from entering the movable frame 17;

[0045] The sleeve rod 9 reciprocates, so that the pressing plate 11 reciprocates along the processing pipe 2, and cooperates with the wedge block 12 to concentrate the vegetables at the bottom of the processing pipe 2 to the middle position, which is convenient for the rolling gear 5 to perform circular motion again, and is convenient for entering the adsorption tube 20;

[0046] It is worth noting that the distance between the pressing plate 11 and the adjacent rolling gear 5 changes all the time (sometimes larger, sometimes smaller), thereby squeezing the vegetables between the rolling gear 5 and the pressing plate 11, squeezing the vegetables at this position;

[0047] While the crushing gear 5 makes a circular motion, it drives the pressing plate 14 to further crush the vegetables at the bottom of the processing pipe 2;

[0048] The working principle of the adsorption assembly: by covering the lid to maintain the sealing of the entire device, after the rolling gear 5 acts for a period of time, the negative pressure adsorption device is turned on to allow the vegetables at the bottom of the processing pipe 2 to fall back onto the two rolling gears 5 through the adsorption tube 20, so as to facilitate multiple crushing and processing of the vegetables;

[0049] The end of the adsorption tube 20 is an inclined section, which ensures that the vegetables slide down on the one hand, and allows the vegetable juice to flow from the inclined surface and enter the collection box through the connecting hole 21 on the other hand (the negative pressure adsorption device is not turned on at this time, the baffle 22 is not tightly pressed against the outer wall of the adsorption tube 20, and the connecting hole 21 is not blocked). When the negative pressure adsorption device is turned on, the baffle 22 is tightly pressed against the outer wall of the adsorption tube 20 through the negative pressure. At the same time, an electric rod is provided in the processing table 1 to press the baffle 22 to rotate the baffle 22. The baffle 22 is tightly pressed against the outer wall of the adsorption tube 20 to block the connecting hole 21, ensuring the negative pressure adsorption effect, so that the vegetable residue enters the top of the rolling gear 5 again for further processing.

[0050] Embodiment 2

[0051] Please refer to Figure 10-11 The top of the pressing plate 14 is in an arc shape that is adapted to the movement of the rolling gear 5.

[0052] In the present embodiment, relative to the first embodiment, the pressure plate 14 in the first embodiment is located below the rolling gear 5, the action surface between the rolling gear 5 and the pressure plate 14 is small, and the effect on the vegetables is small. Only the bottom and side of the pressure plate 14 press down and push the vegetables at the bottom of the processing pipe 2. In the present embodiment, the action surface between the rolling gear 5 and the pressure plate 14 is increased by setting the top of the pressure plate 14 in an arc shape adapted to the rolling gear 5. On the one hand, the action of the bottom and side of the pressure plate 14 is ensured, while the top of the pressure plate 14 and the rolling gear 5 once again crush the vegetables.

The outer surface of the processing pipeline 2 is fixedly connected with a motor 13. The output shaft of the motor 13 penetrates into the processing pipeline 2 and is connected and fixed to the first rotating shaft 6.

[0056] In this embodiment, relative to the first embodiment, the connection relationship between the sleeve 8 and the processing pipeline 2 is changed from fixed to rotating connection, and the connection relationship between the sleeve rod 9 and the pressure plate 11 is changed from fixed to sliding connection. In this mode, the sleeve 8 makes a small angle shake, thereby driving the sleeve rod 9 to synchronously make a vertical shake, driving the pressure plate 11 to reciprocate along the processing pipeline 2. On the one hand, the area of ​​the pressure plate 11 along the processing pipeline 2 is not fixed, and on the other hand, the circular motion trajectory of the other rolling gear 5 (corresponding to the second rotating shaft 7) is not fixed, thereby increasing the rolling effect.
