[0002] Vegetables refer to a type of plants or fungi that can be cooked and made into food. Vegetables are one of the essential foods in people's daily diet. Vegetables can provide a variety of nutrients such as vitamins and minerals necessary for the human body. There are many types of vegetables.

[0003] After the vegetables are planted and mature, they need to be sampled for quality. Through sample testing, we can know the quality of the vegetables. The length, weight, size, aroma, taste and nutrition of the vegetables are all important parameters for evaluating the quality of vegetables. These parameters can help determine the maturity of the vegetables, the appropriate harvest time and the possible yield.

[0004] Vegetables are planted on a large scale and harvested from the fields when they are mature. The harvested vegetables are randomly sampled for quality inspection. In the process of sampling, the randomness of the sampling must be ensured. Staff are often required to randomly sample vegetables for measurement and testing.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0036] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, this application proposes a vegetable quality sampling station.

[0037] In a typical implementation of the present application, Figure 1 and Figure 2 As shown, a vegetable quality sampling station comprises:

[0038] A sampling inspection table 1 is provided, and a conveying and placing conveyor belt 2 is arranged on one side of the sampling inspection table 1. A middle hole 6 is opened on one side of the sampling inspection table 1, and a moving rod 7 is movably installed in the middle hole 6. A first sampling inspection and metering station 3, a second sampling inspection and metering station 4 and a third sampling inspection and metering station 5 are arranged on the top of the sampling inspection table 1. There are three storage holes 10, which are respectively located in front of the first sampling inspection and metering station 3, the second sampling inspection and metering station 4 and the third sampling inspection and metering station 5. During the sampling inspection process, the first sampling inspection and metering station 3, the second sampling inspection and metering station 4 and the third sampling inspection and metering station 5 are arranged on the sampling inspection table 1. Through the setting of multiple stations, each sampling inspection and metering station can measure different types of vegetables (for example, the first sampling inspection and metering station 3 can measure the size and length of the sampled vegetables, the second sampling inspection and metering station 4 can measure the weight of the sampled vegetables, and the third sampling inspection and metering station 5 can measure the quality of the sampled vegetables). Through the design of multiple stations, different measurement sampling types can be provided for different vegetables.

[0039] As a preferred implementation in this embodiment, Figure 2 , Figure 5 , Figure 6 , Figure 8 , Fig. 9 and Fig.10As shown, the random sampling component 23 is arranged on the sampling inspection table 1, and is used for randomly sampling the taken vegetables. The random sampling component 23 includes a sampling plate 27 installed above the moving rod 7, and a side bracket 24 is fixedly installed on the top of the moving rod 7. A rotating bearing 25 is fixedly installed on the top of the side bracket 24. A rotating sleeve 26 is rotatably installed in the rotating bearing 25. The rotating sleeve 26 is fixedly installed at the bottom of the sampling plate 27. A bottom rotating shaft 31 is rotatably installed on the top of the moving rod 7, and a rotating gear 32 is fixedly sleeved on the bottom rotating shaft 31. A rack 33 is fixedly installed on one side of the sampling inspection table 1. The bar 33 is meshed with the rotating gear 32, a bottom notch 34 is provided at the bottom of the rotating sleeve 26, the top of the bottom rotating shaft 31 extends into the bottom notch 34, a reverse block 35 is rotatably mounted on the inner wall of the bottom notch 34, an extrusion spring 36 is fixedly mounted on the reverse block 35 and the inner wall of the bottom notch 34, a plurality of arc-shaped fixed blocks 37 are fixedly mounted on the outer side of the bottom rotating shaft 31, the arc-shaped fixed blocks 37 are adapted to the reverse block 35, an internal groove 28 is provided at the top of the sampling disk 27, a plurality of plug-in grooves 29 are provided on the inner wall of the internal groove 28, and a partition plate 30 is plugged into the plug-in groove 29.

[0040] The vegetables harvested in small batches are placed on the conveyor belt 2 for storage and sampling by the metering personnel. The sampling personnel sit on the metering chair 40. The bottom of the metering chair 40 is provided with a universal wheel. When randomly picking up vegetables on the conveyor belt 2, the universal wheel can move back and forth. When moving, the L-shaped fixed rod 39 can be driven to move, thereby driving the moving rod 7 to move. When a large number of randomly picked vegetables are sampled, in order to ensure the randomness of the sampling, the taken multiple vegetables are placed on the sampling plate 27. When the moving rod 7 moves, it can drive the rotating sleeve 26 and the bottom rotating shaft 31 to move, and the rotating gear 32 is engaged with the rack 33, thereby driving The movable bottom shaft 31 rotates, and in the process of moving from the first sampling and metering station 3 to the second sampling and metering station 4, the rotating gear 32 rotates clockwise, and the reverse clamping block 35 is located between the two adjacent arc-shaped fixed blocks 37. Based on the principle of the ratchet mechanism, the rotating sleeve 26 is synchronously driven to rotate, thereby driving the upper sampling disk 27 to rotate. When it moves from the first sampling and metering station 3 to the second sampling and metering station 4 and stops moving, the bottom shaft 31 does not rotate at this time, and the rotating sleeve 26 can still rotate. Through the rotation of the sampling disk 27, vegetables can be more randomly selected for metering and sampling, avoiding the problem of subjective human rotation of vegetables, resulting in inaccurate metering and sampling.

[0041] Furthermore, in the above scheme, a number of limit posts 8 are provided to limit the horizontal movement of the moving rod 7. The sampling tray 27 is divided into more placement areas by the partition plate 30. The partition plate 30 can be adjusted according to the size of the vegetables, so that a larger number of vegetables can be placed. Through continuous rotation, the sampling tray 27 can be automatically stopped from rotating, or the sampling tray 27 can be manually stopped from rotating after a certain period of time. The vegetables closest to the front can be used as the sampling and measuring objects. During the rotation process, a cover can be added above the sampling tray 27 to avoid direct observation of the vegetables inside and affect the randomness of vegetable selection.

A reset spring 16 is fixedly installed between the two L-shaped guide blocks 15, and the moving rod 7 below the storage hole 10 is disconnected and fixedly connected by two interruption connecting rods 20. Two side protection plates 22 are provided in the middle hole 6, and the two side protection plates 22 are arranged on both sides of the metering and storage conveyor belt 21. A plurality of limit columns 8 are fixedly installed on the inner wall of the middle hole 6, and the limit columns 8 movably penetrate the moving rod 7, and a label placement box 46 is fixedly installed on the side of the moving rod 7.

[0043] During the movement of the moving rod 7, the arc-shaped groove 19 will squeeze the push block 17 upward, and the two driving rods 18 will push the two L-shaped guide blocks 15 to slide on the guide column 14. The two blocking plates 11 will move away from each other, and a storage hole 10 corresponding to the sampling and metering station will be opened. After the vegetables are metered and sampled, qualified or unqualified vegetables are packaged, and the corresponding measurement results are taken out from the label placement box 46, affixed to the vegetable packaging bag, and put into the vegetable packaging bag from the storage hole 10, falling on the metering and storage conveyor belt 21 below, and transported to one side for the convenience of staff to conduct statistics, so as to know the quality of the batch of vegetables.

[0044] Furthermore, in the above scheme, after the moving rod 7 moves, the two L-shaped guide blocks 15 are driven back to their original positions by the elastic force of the reset spring 16, and the two blocking plates 11 will block the sealed storage holes 10 to ensure the horizontal integrity of the sampling table 1 and prevent other vegetables from falling.
