Technical Field

[0001] This utility model relates to the field of agricultural product testing technology, specifically a portable sample pretreatment device for rapid field testing of agricultural products. Background Technology

[0002] In the agricultural product quality and safety testing system, rapid field testing plays a crucial early warning role, enabling the timely detection of potential problems in agricultural products and safeguarding consumer health and safety. Portable sample pretreatment devices, as key equipment in rapid field testing, directly determine the accuracy and timeliness of subsequent test results, and also affect the efficient execution of testing operations in complex field environments.

[0003] Currently, when pre-processing agricultural product samples, multiple sets of independently functional pre-processing tools are often carried during the process. Since the existing multiple sets of tools lack a unified storage and integrated design, they need to be packed into different storage bags or toolboxes. This not only increases the overall carrying volume and weight, increasing the carrying burden on testing personnel when moving in the field, but also poses a risk of tools being lost during transportation, which directly affects the normal conduct of field pre-processing operations. Therefore, there is a need for a portable sample pre-processing device for rapid field testing of agricultural products. Utility Model Content

[0004] The purpose of this utility model is to provide a portable sample pretreatment device for rapid field testing of agricultural products, thereby solving the problems mentioned in the background art. To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a portable sample pretreatment device for rapid field testing of agricultural products, comprising: A protective housing, wherein a connecting seat is fixedly provided at the top of the protective housing; The material receiving and discharging component includes two connecting shafts, one end of each connecting shaft being rotatably mounted on both sides of the protective housing. Connecting rods are fixedly mounted on the outer walls of both connecting shafts, and two movable shafts are slidably mounted on the inner walls of both connecting rods. Two tool plates are fixedly mounted on one end of each of the four movable shafts. Protective plates are fixedly mounted on opposite sides of the two tool plates. A fixed frame is rotatably mounted on the top of the upper protective plate, and an elastic block is fixedly mounted on the top of the fixed frame. The top of the elastic block engages with the top of the connecting seat.

[0005] Furthermore, two through grooves are formed on one side of the connecting rod, and the inner wall of the through groove is slidably connected to the outer wall of the moving shaft.

[0006] Furthermore, two relief grooves are symmetrically formed on both sides of the protective shell, and the height of the four relief grooves is adapted to the outer diameter of the moving shaft.

[0007] Furthermore, the material receiving and discharging component also includes four baffles, one side of each baffle is fixedly mounted on the outer wall of the four moving shafts, and the outer wall of the baffle is slidably connected to the inner wall of the clearance groove.

[0008] Furthermore, the height of the stop bar is adapted to the height of the relief groove, and the length of the stop bar is longer than the length of the relief groove.

[0009] Furthermore, a battery storage box is fixedly provided at the bottom of the protective shell, and pads are fixedly provided on all four sides of the bottom of the battery storage box.

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.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0018] Please see Figure 1-4 As shown, this utility model is a portable sample pretreatment device for rapid field testing of agricultural products, comprising: The protective housing 11 has a connecting seat 111 fixedly provided at its top end; The material receiving and discharging component includes two connecting shafts 21. One end of each connecting shaft 21 is rotatably mounted on both sides of the protective housing 11. Connecting rods 22 are fixedly mounted on the outer walls of both connecting shafts 21. Two moving shafts 23 are slidably mounted on the inner walls of both connecting rods 22. Two tool plates 24 are fixedly mounted on one end of each of the four moving shafts 23. Protective plates 25 are fixedly mounted on opposite sides of each tool plate 24. A fixing frame 26 is rotatably mounted on the top of the upper protective plate 25. An elastic block 27 is fixedly mounted on the top of the fixing frame 26. The top of the elastic block 27 is engaged with the top of the connecting seat 111. The connecting rod 22 is used to drive the two tool plates 24 to move in opposite directions, so as to facilitate the inward storage of the tool plates 24 or the outward opening of the tool plates 24. The fixing bracket 26 is L-shaped, and its top end contacts the inner top end of the connecting seat 111. The top end of the connecting seat 111 is provided with a locking hole that matches the elastic block 27. The top end of the tool plate 24 is fixed with different functional tools for the pretreatment of agricultural product samples.

[0019] Two through grooves 221 are provided on one side of the connecting rod 22, and the inner wall of the through groove 221 is slidably connected to the outer wall of the moving shaft 23. The inner diameter of the through groove 221 is matched with the outer diameter of the moving shaft 23.

[0020] Two clearance grooves 112 are symmetrically provided on both sides of the protective shell 11, and the height of the four clearance grooves 112 is adapted to the outer diameter of the moving shaft 23. The clearance groove 112 is used to allow the moving shaft 23 to move and avoid motion interference between the moving shaft 23 and the protective housing 11.

[0021] The feeding and receiving component also includes four baffles 28. One side of each baffle 28 is fixedly mounted on the outer wall of the four moving shafts 23, and the outer wall of the baffle 28 is slidably connected to the inner wall of the clearance groove 112. The baffle 28 is used to shield and protect the relief groove 112, so that when the sample pretreatment device is not in use, external dust is prevented from entering the protective housing 11 through the relief groove 112.

[0022] The height of the stop bar 28 is adapted to the height of the relief groove 112, and the length of the stop bar 28 is longer than the length of the relief groove 112. The width of the stop bar 28 is smaller than the width of the relief groove 112, and one end of the stop bar 28 passes through one end of the relief groove 112 and slides in fit with the relief groove 112.

[0023] A battery storage box 12 is fixedly installed at the bottom of the protective shell 11, and pads 13 are fixedly installed on the four sides of the bottom of the battery storage box 12. The battery storage box 12 is used to provide power to the entire sample pretreatment apparatus.

[0024] The distance between the connecting shaft 21 and the pad 13 is greater than the distance between the connecting shaft 21 and one end of the connecting rod 22; This prevents the bottom of the connecting rod 22 from contacting and wearing with the ground when it rotates to the vertical position.

[0025] Working principle: When using the sample pretreatment tool to test agricultural products, press the elastic block 27 inward and rotate the fixing frame 26 outward until the fixing frame 26 is rotated to a vertical position. Then pull the fixing frame 26 outward. The outward movement of the fixing frame 26 drives one of the tool plates 24 to move outward through the protective plate 25. The outward movement of the tool plate 24 drives the connecting rod 22 to rotate through the moving shaft 23, which in turn drives the other moving shaft 23 to move the other tool plate 24 in the opposite direction until the moving shaft 23 moves to contact one end of the relief groove 112. When not performing testing, push the fixing frame 26 inward. The inward movement of the fixing frame 26 drives the two tool plates 24 to move towards each other through the protective plate 25 until the protective plate 25 contacts the protective shell 11. Then rotate the fixing frame 26 in the opposite direction until the elastic block 27 at the top of the fixing frame 26 engages with the connecting seat 111. This unified and integrated design of tools not only reduces the overall carrying volume and weight, reducing the carrying burden of testing personnel in field operations, but also avoids the normal operation of field pretreatment due to tools being left behind during transportation.

[0026] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes: The auxiliary support component includes two fixed seats 31 fixed on both sides of the protective shell 11. Each of the four fixed seats 31 is rotatably provided with a support rod 32. The top ends of the two support rods 32 located on the same side are in contact with the bottom end of the tool plate 24. Working principle: When the two tool plates 24 are moved outward and opened, the support rods 32 on both sides of the protective shell 11 are rotated outward until the support rods 32 are rotated to a vertical state. The support rods 32 can provide auxiliary support for the tool plates 24, thereby improving the overall stability of the tool plates 24.
