Description

Technical Field

[0001] The utility model belongs to the technical field of environmental detection and sampling, and particularly relates to a portable sampling device for environmental detection. Background Art

[0002] Environmental testing is fundamental to environmental protection and scientific research. The accuracy of its data directly impacts subsequent environmental management, policymaking, and scientific research conclusions. In on-site environmental monitoring, the sampling process is crucial; it's the prerequisite for obtaining authentic and valid environmental data.

[0003] While portable sampling devices play an important role in environmental monitoring, some existing devices still have some problems. In particular, the sample cannot be screened immediately after scooping. Without immediate screening, the mixed sample may contain particles of different sizes, which increases the difficulty of subsequent screening. The screening process requires more precise operation and longer time to ensure that particles of different sizes are effectively separated. Utility Model Content

[0004] In order to overcome the problem that the existing sampling device for environmental testing cannot immediately screen the sample after scooping it, the subsequent screening, collection and processing of the sample is difficult, time-consuming and labor-intensive.

[0005] The technical solution of the utility model is: a portable sampling device for environmental detection, including a sampling shovel assembly, a screening assembly, and a collection assembly; a screening assembly is provided at the lower end of the sampling shovel assembly; a collection assembly is provided at the lower end of the screening assembly; the sampling shovel assembly includes a shovel body, a shovel handle, and a transmission handle; the screening assembly includes a screening shell, a first transmission shaft, a second transmission shaft, a rotating paddle, and a porous screening plate; the collection assembly includes a sampling box and a partition plate.

[0006] Preferably, the second transmission shaft is driven to rotate by holding the transmission handle, and the rotation of the second transmission shaft drives the first transmission shaft and the rotary paddle to rotate. At this time, the sample above the porous sieve plate is pushed by the rotating rotary paddle to complete the upper and lower screening of the sample particles by the porous sieve plate, and the coarse particles are discharged into one side of the partition plate of the sampling box, while the fine particles enter the other side of the partition plate for separate collection, which solves the problem of the existing sampling device for environmental testing, because the sample cannot be screened immediately after scooping, which makes the subsequent screening, collection and processing of the sample difficult and time-consuming.

[0007] Preferably, a shovel handle is provided at one end of the outer side of the shovel body, and the shovel handle is fixedly connected to the shovel body; a screening shell is provided at the lower end of the shovel body, and the screening shell is fixedly connected to the shovel body, and the rotating transmission handle provides power for the second transmission shaft to drive the first transmission shaft to rotate, and the driving force of the transmission handle is driven by the sampling personnel on site, which effectively improves the screening efficiency of the sampling and improves the portability of the device.

[0008] Preferably, a first transmission shaft is provided inside the screening housing, and the first transmission shaft is rotationally connected to the screening housing bearing; a second transmission shaft is provided at the upper end of the first transmission shaft, and the second transmission shaft is transmission-connected to the first transmission shaft.

[0009] Preferably, a transmission handle is provided on one side of the shovel body, and the transmission handle is rotatably connected to the second transmission shaft.

[0010] Preferably, a rotating paddle is fixedly provided around the outer side of the first transmission shaft; a porous screening plate is provided below the rotating paddle, and the porous screening plate is fixedly connected to the inner wall slot of the screening shell, and the second transmission shaft is driven to rotate by holding the transmission handle, and the rotation of the second transmission shaft drives the first transmission shaft and the rotating paddle to rotate. At this time, the sample above the porous screening plate is pushed by the rotating rotating paddle to complete the upper and lower screening of the sample particles by relying on the porous screening plate, and the coarse particles are discharged into one side of the partition plate of the sampling box, while the fine particles of the sample particles enter the other side of the partition plate for separate collection.

[0011] Preferably, a sampling box is provided below one side of the screening housing, and the sampling box is fixedly connected to the output end shell of the screening housing by means of threads.

[0012] Preferably, a partition plate is provided inside the sampling box, and the upper and lower sides of the partition plate are respectively connected to the discharge ports of the upper and lower layers of the porous sieve plate. The partition plate is used to separate the internal space of the sampling box, so that the sieved samples can be distinguished and collected independently according to particle size.

[0013] Beneficial effects of the utility model:

[0014] 1. The existing sampling device for environmental testing cannot immediately screen the sample after it is scooped off, which makes it difficult and time-consuming to screen and collect the sample later. The second transmission shaft is driven to rotate by hand through the transmission handle, and the rotation of the second transmission shaft drives the first transmission shaft and the rotating paddle to rotate. At this time, the sample above the porous screening plate is pushed by the rotating rotating paddle to complete the upper and lower screening of the sample particles by the porous screening plate. The coarse particles are discharged into one side of the partition plate of the sampling box, and the fine particles are discharged into the other side of the partition plate for separate collection. This solves the problem that the existing sampling device for environmental testing cannot immediately screen the sample after it is scooped off, which makes it difficult and time-consuming to screen and collect the sample later.

[0015] 2. Through the setting of the transmission handle, the rotating transmission handle provides power for the second transmission shaft to drive the first transmission shaft to rotate, and the driving force of the transmission handle is driven by the sampling personnel on site, which effectively improves the screening efficiency of the sampling and improves the portability of the device.
