Description

Technical Field

[0001] This utility model belongs to the field of agricultural product testing technology, and in particular relates to a sampling device for agricultural product testing. Background Technology

[0002] To ensure the safety and health of agricultural products, sampling and testing are crucial steps in guaranteeing their quality and safety. During testing, it is necessary to measure pesticide residue levels in fruits and vegetables to ensure the quality and safety of agricultural products.

[0003] For example, Chinese utility model CN221038072U discloses an agricultural product testing and sampling device. The device involves placing the agricultural product to be tested into a net bag, and using a connecting rod to drive a squeezing rod to squeeze the product in the net bag, causing the juice and residue of the product to separate. The juice is then collected through a funnel and flows into a test tube, thus completing the sampling.

[0004] However, in the aforementioned existing technologies, when nets are used to load agricultural products, the nets are easily broken when the nets and agricultural products are squeezed during actual use, causing the agricultural products to spill out, which seriously affects the reliability of use. In addition, the nets need to be fixed to the mounting block with storage ropes, which is inconvenient to install and has poor overall usability. Utility Model Content

[0005] The purpose of this invention is to provide a sampling device for agricultural product testing. The device stores agricultural products in a storage cup and uses a squeezing column to extract juice samples, thus solving the problems of poor reliability and ease of use of existing sampling devices.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a sampling device for agricultural product testing, comprising a base and a storage cup. The upper surface of the base is provided with a side plate and a support platform. A pressure plate is slidably connected to the side plate, and a linear drive assembly is connected thereto, used to drive the pressure plate to move up and down via the linear drive assembly. The pressure plate is connected to a squeezing column. The lower end of the storage cup has a funnel-shaped structure, and the inner wall of the storage cup has a stepped surface, forming a stepped hole structure. A filter plate is installed inside the storage cup, used to drive the squeezing column downwards via the pressure plate, squeezing the agricultural product inside the storage cup, causing the juice of the agricultural product to flow out from the lower end of the storage cup. The support platform has an installation hole, and the outer wall of the storage cup has a flange structure, used to allow the lower end of the storage cup to pass through the installation hole and be supported by the flange structure.

[0008] As a preferred embodiment of this utility model, a connecting rod is fixedly connected to the lower end of the pressure plate, and a connecting hole is provided on the lower end face of the connecting rod. The upper end of the extrusion column is connected and fixed to the connecting rod through the connecting hole.

[0009] In a preferred embodiment of this invention, the extrusion column and the connecting hole are connected by a thread.

[0010] As a preferred technical solution of this utility model, the extrusion column and the connecting hole are fitted with a clearance, and a hand-tightening screw is threaded on the side of the connecting rod. The hand-tightening screw penetrates the side wall of the connecting hole and is used to extrude and fix the extrusion column by the end of the hand-tightening screw.

[0011] As a preferred embodiment of the present invention, the linear drive assembly includes a vertically arranged lead screw and a lead screw nut that cooperates with the lead screw, and the lead screw nut is fixedly connected to the pressure plate.

[0012] As a preferred embodiment of this utility model, a worm gear is fixedly connected to the upper end of the lead screw, and a worm gear meshing with the worm gear is rotatably connected to the side plate. A crank handle is connected to the shaft of the worm gear.

[0013] As a preferred technical solution of this utility model, the stepped surface of the storage cup is provided with a plurality of liquid flow channels, and the side wall of the storage cup is provided with a guide channel that is connected to the liquid flow channels one by one, so that the juice of the agricultural product flows to the lower end of the storage cup through the guide channel and the liquid flow channel.

[0014] This utility model has the following beneficial effects:

[0015] This invention places agricultural products inside a storage cup, and uses a pressure plate to move a squeezing column downwards. The squeezing column squeezes the agricultural products inside the storage cup, causing the juice of the agricultural products to flow out from the lower end of the funnel-shaped structure of the storage cup, thereby achieving sampling. This effectively improves the overall reliability and convenience of use.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0026] Please see Figure 1 and 2 As shown, this utility model is a sampling device for agricultural product testing, including a base 1 and a storage cup 2. The upper surface of the base 1 is provided with a side plate 101 and a support platform 3. The side plate 101 is slidably connected to a pressure plate 4 through a guide rail slider assembly, and is also connected to a linear drive assembly for driving the pressure plate 4 to move up and down through the linear drive assembly. The pressure plate 4 is connected to an extrusion column 401.

[0027] Specifically, a connecting rod 402 is welded or screwed to the lower end of the pressure plate 4. A connecting hole is provided on the lower end face of the connecting rod 402, and the upper end of the extrusion column 401 is connected and fixed to the connecting rod 402 through the connecting hole. If the connecting hole is a threaded hole, the extrusion column 401 is connected to the connecting hole by thread; or the extrusion column 401 and the connecting hole are clearance fitted, and a hand screw 403 is threaded to the side of the connecting rod 402. The hand screw 403 penetrates the side wall of the connecting hole and is used to extrude and fix the extrusion column 401 through the end of the hand screw 403.

[0028] The extrusion column 401 is connected to the connecting rod 402 by a threaded connection or by a hand-tightened screw 403, which makes it easy to disassemble the extrusion column 401 and facilitate disassembly and cleaning after sampling.

[0029] The side plate 101 is fixedly connected to an end plate at its upper end. The linear drive assembly includes a vertically arranged lead screw 6 and a lead screw nut 601 that cooperates with the lead screw 6. The lower end of the lead screw 6 is rotatably connected to the base 1, and the upper end is rotatably connected to the end plate. The lead screw nut 601 is fixedly connected to the pressure plate 4. By rotating the lead screw 6, the pressure plate 4 is driven to move up and down.

[0030] A worm gear 602 is fixedly connected to the upper end of the lead screw 6. A worm 603 that meshes with the worm gear 602 is rotatably connected to the end plate at the upper end of the side plate 101. A crank 604 is connected to the shaft of the worm 603. The worm 603 is rotated by the crank 604, which in turn drives the lead screw 6 to rotate through the worm gear 602. The meshing transmission between the worm gear 602 and the worm 603 can save effort and improve the convenience of manual rotation.

[0031] like Figure 3 and 4 As shown, the lower end of the storage cup 2 has a funnel-shaped structure, allowing the juice to collect inside the storage cup 2 and flow out from the lower end, providing convenient collection. The inner wall of the storage cup 2 has a stepped surface 201, making the inner wall of the storage cup 2 have a stepped perforated structure, and a filter plate 5 is installed inside the storage cup 2. The filter plate 5 is placed on the stepped surface 201 of the storage cup 2, allowing the filter plate 5 to be quickly removed, thereby facilitating the cleaning of the filter plate 5 and the inside of the storage cup 2 after use.

[0032] The support platform 3 has an inverted U-shaped structure, with mounting holes on the top plate. The outer wall of the storage cup 2 has a flange structure 202, which allows the lower end of the storage cup 2 to pass through the mounting holes and is supported by the flange structure 202.

[0033] During sampling, the agricultural product to be tested is placed in the storage cup 2. The screw 6 is rotated to drive the extrusion column 401 to move down through the pressure plate 4. The lower end of the extrusion column 401 is inserted into the storage cup 2 and the agricultural product in the storage cup 2 is squeezed, so that the juice of the agricultural product flows out from the lower end of the storage cup 2 and can be collected in the storage cup 2 through a container or test tube.

[0034] As another optimization scheme, the stepped surface 201 of the storage cup body 2 is provided with a number of liquid flow channels 203. The liquid flow channels 203 are arranged radially along the storage cup body 2 and evenly distributed along the circumference of the storage cup body 2.

[0035] Furthermore, the side wall of the storage cup 2 is vertically provided with a guide channel 204 that is connected to the liquid flow channel 203, so that the juice of the agricultural product flows from the guide channel 204 and the liquid flow channel 203 to the lower end of the storage cup 2.

[0036] By opening the guide channel 204 and the liquid flow channel 203, when the filter holes of the filter plate 5 are blocked during the extrusion process, the juice can flow downward through the guide channel 204 and the liquid flow channel 203, avoiding the situation where the juice accumulates inside the storage cup 2 and cannot be discharged, thereby greatly improving the sampling efficiency of the juice and the overall reliability of use.
