Description
Technical Field
[0001] The utility model belongs to the technical field of experimental platforms, and particularly relates to a soil sample preparation workbench. Background Art
[0002] Soil is an important base for the growth and reproduction of crops. Soil testing plays an important role in guiding scientific fertilization operations and increasing the yield and quality of crops. Before soil testing, soil samples need to be prepared on the workbench. Generally, the blocky or large-particle soil needs to be ground into fine powder, and then sieved and packaged into several soil samples. A lot of dust will be generated during the preparation of soil samples. Operators are prone to inhaling dust, which can cause harm to the body. Therefore, dust needs to be sucked away in time during the preparation of soil samples to reduce the occurrence of occupational diseases.
[0003] At present, the detection and production of soil samples are generally carried out on an ordinary workbench. Although the workbench is equipped with a fan, the fan is located on the top of the workbench. The soil will fall down due to its own gravity, which can easily cause cross-infection of soil samples and affect the test results. In recent years, some people have proposed to set the exhaust port on the workbench surface, such as the patent "A Soil Grinding Operation Table" (CN215466666U), which automatically collects scattered soil by means of downward exhaust, which can reduce the cross-infection of soil samples and better meet the production requirements of soil samples. However, during the soil sample preparation process, the workbench surface is generally placed with sieves, hammers, containers and other items to block the exhaust port of the table, and the dust removal effect is still poor. On the other hand, the number and requirements of soil samples in different batches are different. Some need to occupy the entire workbench, while others only occupy part of it. The current exhaust holes are not adjustable and cannot meet different test requirements well. Utility Model Content
[0004] The utility model aims to provide a soil sample preparation workbench to solve the problem that the existing downdraft type soil sample preparation workbench has poor dust removal effect and cannot better meet the test requirements.
[0005] The specific technical solutions are as follows:
[0006] A soil sample preparation workbench comprises a workbench body, a table top, and an exhaust device. A first exhaust port is arranged on the table top of the workbench body, and the first exhaust port is connected to the exhaust device through an exhaust pipe. The table top is arranged above the first exhaust port, and a plurality of first air holes are arranged on the table top at intervals. A second exhaust port is also arranged on the inner lower part of the workbench body, and the second exhaust port is also connected to the exhaust device through the exhaust pipe. An air regulating plate is arranged at the second exhaust port, and a vertical long strip second air hole is arranged on the air regulating plate.
[0007] Preferably, the air regulating plate is a shutter, and the blades of the shutter are installed vertically.
[0008] Preferably, the blades of the shutter include a first blade and a second blade that can be adjusted independently, the first blade is arranged on the left side of the shutter, and the second blade is arranged on the right side of the shutter. When in use, the first blade tilts to the left to draw air to the left side of the facade, and the second blade tilts to the right to draw air to the inside of the right side.
[0009] Preferably, a dust collecting trough is provided below the air regulating plate, and the dust collecting trough is detachably connected to the air regulating plate or the workbench body.
[0010] Preferably, a baffle is further provided on the side of the air regulating plate away from the second air exhaust port, and the baffle is slidably connected to the air regulating plate or the workbench body.
[0011] Preferably, a brush is further provided on the side of the baffle plate close to the air regulating plate.
[0012] Preferably, the table top of the workbench body is in a groove shape, and slide grooves are provided on both sides of the groove, the table plate is detachably mounted on the slide grooves, and the table plate is flush with the four sides of the table top.
[0013] Preferably, a filter is provided at the first air outlet.
[0014] Preferably, a transparent dust cover is provided on the upper portion of the workbench body.
[0015] Preferably, the workbench body above the table plate is made of glass fiber reinforced plastic or PVC material to avoid corrosion and shedding of the steel plate affecting sample preparation.
[0016] Compared with the existing technology, the utility model has the following beneficial effects:
[0017] 1. The utility model sets the first air outlet on the table top of the workbench body and sets the second air outlet on the inner lower part of the workbench body, so as to better exhaust the workbench, especially when there are many obstructions such as trays on the table top of the workbench, the dust can be sucked away in time to protect the health of the operator. Among them, the vertical long second air hole can suck away the dust more evenly.
[0018] 2. The utility model sets a louver with vertically installed blades at the second air outlet, and the first blade and the second blade can be adjusted independently. When in use, the first blade tilts to the left to draw air to the left side of the facade, and the second blade tilts to the right to draw air to the inside of the right side. Compared with the horizontal installation of blades to draw air up and down, it is not easy to cause sample mixing.
[0019] 3. The utility model can also install a movable baffle on the outside of the air regulating plate, so that the size and position of the air outlet can be adjusted according to the sample volume, and dust can be sucked away more effectively.
