DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0036] Embodiment 1:

[0037] Reference Figure 1 -Attached Figure 4 , a heavy metal inspection equipment for agricultural products based on food safety, comprising:

[0038] Box body;

[0039] A circular box cavity 1 is provided inside the box body and has an opening at the top;

[0040] The filter plate 2 is fixedly connected to the box body and is located inside the circular box cavity 1;

[0041] A plurality of filter holes 3 are provided through the upper and lower surfaces of the filter plate 2;

[0042] The cover body 4 is covered on the top of the box body to seal and cover the opening on the top of the circular box cavity 1;

[0043] The rotating shaft 5 is coaxially connected to the cover body 4 and has an upper end and a lower end, and the lower end corresponds to the filter plate 2;

[0044] A wire 6, one end of which is eccentrically disposed with respect to the rotating shaft 5;

[0045] A metal ball 7 is connected to the other end of the wire 6;

[0046] Among them, when the shaft 5 rotates at high speed, the metal balls 7 rise from the bottom of the shaft 5 to the circumferential side of the lower end of the shaft 5 by relying on centrifugal action, and rotate synchronously at high speed, destroying the cells of the vegetable leaves on the filter plate 2 in a point-to-point squeezing manner to make them release juice.

[0047] Through the above technical solution, the blades are first placed on the filter plate 2, and then the cover body 4 is covered to ensure the sealing of the circular box cavity 1, so that the rotating shaft 5 rotates at a high speed, driving the metal ball 7 to rotate synchronously and squeeze the blades on the filter plate 2 by centrifugal action. The blades are squeezed to release juice, which flows down through the filter holes 3 and accumulates inside the box body.

[0048] The box body is composed of a bottom plate 8 and a side ring 9. The top surface of the bottom plate 8 is coaxially fixedly connected to a snap ring 10. A snap groove 11 is provided in the side ring 9. The snap groove 11 is adapted to the snap ring 10. The snap ring 10 can be inserted into and out of the snap groove 11. The filter plate 2 is fixedly connected to the inner wall of the side ring 9. When the side ring 9 is clamped on the bottom plate 8, the juice flowing down from the filter plate 2 can be collected. When the side ring 9 is separated from the bottom plate 8, the juice between the snap ring 10 and the bottom plate 8 can be used, and it is helpful to clean the box body.

[0049] The vertical cross section of the filter plate 2 is in a "V" shape, and it is a circular slope that tilts upward from the center to the periphery, so that the vegetable leaves can be stably placed on the circular slope, and the juice overflowing from the leaves can eventually flow out from the lowest filter hole 3, avoiding excessive juice remaining in the box body;

[0050] A sealing ring 12 is provided on the bottom surface of the cover body 4, a sealing groove 13 is provided on the side ring 9, a rotating groove 14 is provided in the center of the cover body 4, the rotating shaft 5 passes through the rotating groove 14, and the cover body 4 also provides a first annular groove 15, the inner diameter of the first annular groove 15 is the same as the diameter of the rotating groove 14, the outer wall of the rotating shaft 5 is fixedly sleeved with a first annular body 16, the first annular body 16 is located inside the first annular groove 15, the upper end of the rotating shaft 5 is fixedly connected to a driven gear 17, a rotating motor 18 is installed outside the box body, the output shaft of the rotating motor 18 is fixedly connected to a driving gear 19, and the driving gear 19 and the driven gear 17 are meshed and connected with each other;

[0051] Embodiment 2:

[0052] As an improvement to the first embodiment, specifically:

[0053] The outer wall of the rotating shaft 5 is fixedly connected to the connecting block 20, and the connecting block 20 is fixedly connected to the vertical block 21. The vertical block 21 contacts the cover body 4. A through hole 22 is provided in the rotating shaft 5. The through hole 22 has two ports, namely a first port 23 and a second port 24. The first port 23 is located above the cover body 4, and the second port 24 is located below the cover body 4. The wire 6 passes through the through hole 22. The wire 6 is connected to the vertical block 21 through one end of the first port 23 and is connected to the metal ball 7 through one end of the second port 24. A plurality of arc blocks 25 are fixedly connected to the cover body 4. The plurality of arc blocks 25 are equidistantly arranged on the cover body 4. When the rotating shaft 5 rotates, the wire 6 rotates with it and touches the arc surface of the arc block 25.

[0054] Through the above technical solution, the wire 6 will bend along the arc surface when passing through the arc block 25, forming a contraction posture, so that the wire 6 moves in the perforation 22, dragging the wire 6 to control the metal ball 7 to temporarily cancel the squeezing of the vegetable leaves. When the wire 6 leaves the arc block 25, the wire 6 straightens again, and the metal ball 7 hits the vegetable leaves with an impact posture, increasing the damage to the vegetable leaves, so that the juice flows out better and faster.

[0055] Embodiment three:

[0056] As an improvement to the second embodiment, specifically:

[0057] The lower end of the rotating shaft 5 extends downward, and the perforation 22 has a plurality of second ports 24 on the rotating shaft 5. The wire 6 has a plurality of branches, and the number of the branches is the same as the number of the second ports 24. Each branch passes through its corresponding second port 24 and is respectively connected to a metal ball 7. When each metal ball 7 rotates with the rotating shaft 5, it is located at a different height, thereby increasing the squeezing and impact area of ​​the vegetable leaves on the filter plate 2, and destroying the vegetable leaves more comprehensively and quickly to extract juice.

[0058] The testing method includes the steps of selecting juice from vegetable leaves to be tested as sample liquid, which specifically comprises:

[0059] Open the cover 4, place the vegetable leaves to be inspected on the slope of the filter plate 2, and then close the cover 4, so that the vegetable leaves are inside the sealed circular box cavity 1;

[0060] The rotating motor 18 is started to drive the driven gear 17 and the rotating shaft 5 to rotate, so that the metal ball 7 starts to rotate in the circular box cavity 1 until it rises to its maximum height and squeezes the vegetable leaves on the filter plate 2 to make them release juice, which flows down along the filter hole 3 and accumulates inside the box body;

[0061] The side ring 9 is separated from the bottom plate 8, and the juice is located between the clamp ring 10 and the bottom plate 8. After the juice is transferred, the side ring 9 is separated from the cover plate, and the bottom plate 8, the side ring 9 and the cover body 4 are separated into three parts.

[0062] It should be noted that:

[0063] The wire 6 is made of plastic or other materials that are not easy to absorb water, so as to avoid absorbing the juice flowing out of the vegetable leaves;

[0064] Before the cover body 4 is covered on the side ring 9, the teeth of the driven gear 17 and the driving gear 19 need to be aligned to ensure that the driven gear 17 and the driving gear 19 on the cover body 4 are meshed and connected with each other after covering;

[0065] Since it needs to be cleaned with clean water, a protective box can be set outside the rotating motor 18 to prevent water splashing and contacting the rotating motor 18;

[0066] The sealing ring 12 is made of rubber material, and the sealing groove 13 is slightly smaller than the sealing ring 12, so that the sealing ring 12 is inserted into the sealing groove 13 to limit the cover body 4 from rotating;

[0067] Reference Figure 6 and attached Figure 7 When the wire 6 touches the arc block 25, it bends along the arc surface to form a contraction trend, and the metal ball 7 temporarily cancels the squeezing of the vegetable leaves.

[0068] The present invention is conceived to:

[0069] Because conventional knives rotate to slice vegetable leaves to release juice, after slicing, too much juice and fragmented leaves remain on the cutting edge or corners of the knife, making cleaning difficult and slow. In this solution, the knife cuts the leaves in a way that the metal ball 7 squeezes the leaves to release juice. The metal ball 7 is spherical with a smooth and round surface. It applies pressure to the leaves by point squeezing to release juice, keeping the vegetable leaves intact. Compared with knife chopping, the vegetable leaves as a whole will not fly around in disorder, and the juice will not splash over a large area. The vegetable leaves after juicing are easier to pick up and clean. At the same time, the juice remaining on the metal ball 7 is less and it is convenient to use clean water to wash;

[0070] By intermittently shortening the wire 6, the metal ball 7 intermittently stops squeezing the vegetable leaves and accumulates energy. At the moment when the wire 6 is relaxed, the metal ball 7 hits the vegetable leaves and applies greater pressure to the vegetable leaves, so that the vegetable leaves release juice faster.

[0071] After the juice is extracted from the vegetable leaves and transferred, the entire device is disassembled into the chassis 8, the side ring 9 and the cover body 4, and then rinsed with clean water, which is convenient and quick to clean.

[0072] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
