Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-4 As shown, this utility model provides a technical solution: a sample collector for analyzing harmful microorganisms in vegetables, including a base plate 1, a sample box 2 fixedly installed on the top of the base plate 1, a fixing block 3 fixedly installed on the left side of the sample box 2, a vertical shaft 4 fixedly installed on the top of the fixing block 3, a connecting block 5 rotatably installed on the vertical shaft 4, a box cover 6 fixedly installed on the connecting block 5, a feeding hole 7 opened on the box cover 6, a conversion mechanism is provided inside the sample box 2, six sample tubes 8 are movably installed on the conversion mechanism, the conversion mechanism is used to control the six sample tubes 8 to rotate, a vertical plate 9 is fixedly installed on the top right side of the base plate 1, a punching mechanism for cutting vegetables is provided on the vertical plate 9, and four support feet 31 symmetrically distributed in pairs are fixedly installed on the bottom of the base plate 1, and anti-slip pads 32 are fixedly installed on the bottom of each of the four support feet 31.

[0023] In this embodiment, a positioning block 27 is fixedly installed on the right side of the sample box 2, and a positioning plate 28 is fixedly installed on the right side of the box cover 6. A positioning pin 29 is slidably installed on the positioning plate 28. The bottom end of the positioning pin 29 extends into the positioning block 27. A tension spring 30 is sleeved on the positioning pin 29. The bottom end of the tension spring 30 is fixedly connected to the positioning plate 28, and the top end of the tension spring 30 is fixedly connected to the positioning pin 29. By using the tension spring 30, the positioning pin 29 can be controlled to be inserted into the positioning block 27, thus maintaining the stability of the box cover 6.

[0024] In this embodiment, the aforementioned conversion mechanism includes a rotary damping seat 10, a vertical rod 11, a disc frame 12, an external gear ring 14, a motor 15, and an incomplete gear 16. The rotary damping seat 10 is fixedly installed on the bottom inner wall of the sample box 2. The rotary damping seat 10 effectively prevents the vertical rod 11 from continuing to rotate due to inertia when the external gear ring 14 and the incomplete gear 16 disengage. The vertical rod 11 is fixedly installed on the top of the rotary damping seat 10, and the disc frame 12 is fixedly installed on the top of the vertical rod 11. The disc frame 12 has six placement holes 13 arranged in a circular array, and the six sample tubes 8 are respectively... The movable part is installed in the corresponding placement hole 13. The external gear ring 14 is fixedly installed on the vertical rod 11. The motor 15 is fixedly installed on the bottom inner wall of the sample box 2. It should be noted that the motor 15 is set to rotate only one revolution each time it runs. The incomplete gear 16 is fixedly installed on the output shaft end of the motor 15 and meshes with the external gear ring 14. The number of teeth of the external gear ring 14 is six times the number of teeth of the incomplete gear 16. By utilizing the difference in the number of teeth between the external gear ring 14 and the incomplete gear 16, the disc frame 12 can be controlled to rotate 60 degrees for each revolution of the motor 15, thereby replacing the sample tube 8.

[0025] In this embodiment, the aforementioned punching mechanism includes a support base 17, a pressure rod 18, two connecting plates 19, a cross brace 20, a guide tube 21, and a punching tube 22. The support base 17 is fixedly installed on the top of the vertical plate 9. The pressure rod 18 is rotatably installed on the support base 17. The two connecting plates 19 are rotatably installed on the front and rear sides of the pressure rod 18 respectively by bolts. The cross brace 20 is fixedly installed on the left side of the vertical plate 9. The guide tube 21 is fixedly installed on the left side of the cross brace 20. The guide tube 21 can be used to cause the punching tube 22 to move up and down, thus constraining and guiding the movement of the punching tube 22. The punching tube 22 is slidably installed in the guide tube 21 and located above the feeding hole 7. The two connecting plates 19 are rotatably connected to the top of the punching tube 22 by bolts. A spring 23 is fixedly installed on the top of the cross brace 20. The top of the spring 23 is fixedly connected to the pressure rod 18. The spring 23 can push the pressure rod 18 upward to spring back after punching and sampling the vegetables, which is convenient, quick, and improves the punching efficiency.

[0026] In this embodiment, a groove 24 is provided on the right side of the perforated tube 22, and an installation block 25 is fixedly installed on the inner wall of the right side of the guide tube 21. The installation block 25 is slidably installed in the groove 24. A ejector rod 26 is fixedly installed on the left side of the installation block 25. The ejector rod 26 slides in contact with the inner wall of the perforated tube 22. The ejector rod 26 can clean the sample stuck in the perforated tube 22 when the perforated tube 22 rises, which is convenient for the next perforation and sampling.

[0027] In this embodiment, a control switch and a battery are installed on the base plate 1. The motor 15 and the control switch are sequentially connected to the battery via wires to form a circuit. The control switch can control the start and stop of the motor 15.

[0028] With the above structure, the sample collector for analyzing harmful microorganisms in vegetables provided by this utility model can punch and extract samples from localized areas of vegetables containing microorganisms through the perforated tube 22. The ejector rod 26 cleans samples that may be stuck inside the perforated tube 22 as it rises, facilitating subsequent sampling and improving sampling efficiency. It can also control the disc frame 12 to rotate 60 degrees each time, thereby replacing the sample tube 8 and facilitating the receiving of vegetable samples, further improving sampling efficiency. In specific use, the vegetables are placed flat on the lid 6 with the microorganism-containing area above the discharge hole 7. The pressure rod 18 is pressed down, controlling the perforated tube 22 to move downwards and compressing the spring 23. The perforated tube 22 then extracts the samples from the vegetables. After drilling holes in a localized area of ​​the vegetable sample, the control lever 18 rises. Driven by the spring 23, this process is time-saving and labor-saving. During the upward movement of the drilling tube 22, the ejector rod 26 pushes out any vegetable samples that may be stuck inside the drilling tube 22. The samples fall through the discharge hole 7 into the sample tube 8 below. The control motor 15 rotates, driving the incomplete gear 16 to rotate. By utilizing the meshing rotation of the incomplete gear 16 and the external gear ring 14, the disc frame 12 can be rotated 60 degrees, thereby replacing the sample tube 8 for the next drilling and sampling. Once all six sample tubes 8 contain vegetable samples, the control positioning pin 29 moves upward to disengage from the positioning block 27, and the control box cover 6 rotates backward, making it easy to remove and replace the remaining sample tube 8 for the next vegetable sampling.

[0029] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope described in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
