Description
Technical Field
[0001] The utility model relates to a rotary grain sampler, belonging to the technical field of grain quality inspection. Background Art
[0002] During grain storage and preservation, in-warehouse sampling (sampling) and quality inspection are crucial for identifying grain quality issues and implementing timely measures to ensure national food security. National standards require that samples collected from all sampling points within a grain silo be thoroughly and evenly mixed to qualify as qualified and representative samples. Existing small-scale mixers, such as V-type mixers, three-dimensional mixers, spiral mixers, and double-cone mixers, are generally heavy and inconvenient for on-site sample mixing within grain silos. In practice, due to the lack of suitable portable mixing equipment, the samples collected may not represent the actual quality of the grain in the silo, causing inconvenience in subsequent management and frequent disputes between inspection departments and grain storage companies. Specific issues include: 1. Lack of sample mixing. Without suitable mixing equipment, samples at each sampling point are rarely mixed, resulting in samples that are not representative of the grain quality at each layer of the sampling point. 2. Manual sample mixing is uneven. The samples from the sampling points are put into plastic bags and mixed by shaking, but the mixing is uneven. 3. It consumes a lot of manpower. The electric sample transfer machine currently widely used in grain warehouses generally weighs 1-6 kilograms for each sampling point. 4. The samples at each sampling point are not mixed. Because there are many sampling points in each granary, ranging from 8 to more than 30, so many samples (total weight 10-150 kilograms) cannot be mixed by manual operation. The sample dividers currently used in the grain industry mainly include the following: bell-shaped sample dividers, diaphragm-shaped sample dividers, trough-shaped sample dividers, electric centrifugal sample dividers, etc. The above sampling equipment is suitable for laboratories or working environments with relatively few samples. At present, the most commonly used bell-shaped sample divider for processing samples in the warehouse is the bell-shaped sample divider, which requires multiple sampling of samples, which consumes a lot of manpower. In addition, the bell-shaped sample divider cannot mix samples, but only performs simple sampling, so the above problems need to be solved. Utility Model Content
