Problems solved by technology

[0003] Existing grain storage bins need to regularly test the stored grain. The current sampling method is to insert a hollow probe into the grain bin. However, the length of the hollow probe is relatively long and it is inconvenient to splicing operations during use. Therefore, A new stratified sampling device is needed

Abstract

The invention provides a storage granary stratified sampling device, and relates to the field of grain preservation. The storage granary stratified sampling device comprises an advancing head, a counterweight pipe is fixedly connected to the outer surface of the advancing head, a collecting mechanism is fixedly mounted at the position, above the advancing head, in the counterweight pipe, and a sealing mechanism is fixedly mounted at the position, located on one side of the collecting mechanism, in the counterweight pipe. According to the storage granary stratified sampling device, when a collecting cone rotates and moves downwards, an electric control push rod pushes a sliding sleeve to move downwards, a clamping rod is inserted into a connecting hole, a threaded shaft is driven to rotate, a collecting sleeve moves upwards, and a clamping block can drive a touch block to move upwards, so that a sealing plate feeds materials into the collecting sleeve through a feeding hole; and after the clamping block extrudes the through hole touch block, the device is reset, the threaded shaft is separated from the double-end motor, the layered sampling effect can be achieved by periodically starting the sealing plate, and the problem that in the prior art, the operation is inconvenient due to the fact that sampling devices need to be spliced is solved.

Description

technical field [0001] The invention relates to the technical field of grain preservation, in particular to a layered sampling device for grain storage. Background technique [0002] Granary, that is, a special building for storing grain, is used to store a large amount of grain. The construction of granaries should give priority to fully ensuring the safety of grain storage, and consider the needs of grain storage safety from the aspects of the physical properties, physiological characteristics, and ecological characteristics of the grain itself. The choice of warehouse type should be adapted to local conditions, and the appropriate warehouse type should be determined according to the climatic conditions, geological structure, characteristics of grain types, nature and function of grain depots in each region. [0003] Existing grain storage bins need to regularly test the stored grain. The current sampling method is to insert a hollow probe into the grain bin. However, the...
