Automatic detector for grounding of grain sampling stick of sampler

Abstract

The invention relates to an automatic detector for the grounding of a grain sampling stick of a sampler. The detector comprises a transmission chain, a transmission support fixed on the transmission chain, a grain sampling stick connected with the transmission support and a fixed cantilever arranged at the right side of the grain sampling stick. A guide ring is arranged at the lower end of the fixed cantilever; the grain sampling stick is sheathed in the guide ring; an upstream support of the grain sampling stick is fixed at the upper end of the grain sampling stick and is arranged above the transmission support; a though hole is formed in a top plate of the upstream support of the grain sampling stick; an adjusting screw is arranged in the through hole; a contact moving end is arranged at the bottom end of the adjusting screw; the part of the adjusting screw between the top plate and the contact moving end is sheathed with a control spring; a contact static end is fixed on a beam of the transmission support corresponding to the contact moving end; a downstream support of the grain sampling stick is arranged on the grain sampling stick and below the beam; the part of the grain sampling stick between the beam and the downstream support of the grain sampling stick is sheathed with a downstream transmission spring. The detector can avoid sampling dead zones at the bottom layer of a grain vehicle, reduce the number of (lower) limit switches and effectively protect the safe use of the grain vehicle and the sampler.

Description

technical field [0001] The invention belongs to mechanical equipment for checking grain quality, in particular to a grain skewer bottoming detector for an automatic skewer sampler. Background technique [0002] With the advancement of my country's reform and opening up process and the implementation of rural policies to benefit farmers, the enthusiasm for grain production has been unprecedentedly high, and the scale and quality of grain storage, transportation, operation, and grain processing enterprises have been greatly expanded and improved. The grain inspection work of grain enterprises before grain purchase is the only means to evaluate grain quality, and the accuracy of grain inspection and testing data depends on whether the grain samples are authentic and representative. Take a representative sample It is an important part of the grain inspection process, and it is an important link to reduce the loss of grain entering and leaving the warehouse, improve the efficienc...
