Description

Technical Field

[0001] The utility model belongs to the technical field of grain detection, in particular to a picking and testing device. Background Art

[0002] Many grain processing companies on the market store grain in multiple grain depots. To ensure the quality of grain purchases, one of the inspection items that must be done before grain is stored is to sample the grain in the grain truck. When sampling grain, a sampling machine is mostly used. If a different grain depot is used every year, the sampling machine needs to be transferred. However, most traditional sampling machines are fixedly installed, and the cost of disassembly and relocation is high. In addition, the parts of the sampling machine are easily damaged during disassembly and transportation. If each grain depot is equipped with a sampling machine, since the cost and price of existing sampling machines on the market are very high, the machine needs to be installed on-site by professionals after leaving the factory, so the purchase cost and installation cost are higher, which brings a greater burden to users. In response to this, some movable sampling machines have appeared on the market, but the existing movable sampling machines are not easy to transport. If users want to sell or purchase movable sampling machines, especially for export overseas, the transportation cost and difficulty are still high. Utility Model Content
