Coal slime sampling shovel with adjustable collection amount

Abstract

The invention belongs to the field of coal slime sampling technologies and particularly relates to a coal slime sampling shovel with an adjustable collection amount. The shovel comprises a main rod, wherein a push-down rod is arranged in the main rod, a clamping block and a push-up rod are arranged at the upper end of the push-down rod, and the lower end of the push-down rod is connected with a pushing block; a handle perpendicular to the main rod is fixed to the periphery of the upper end of the main rod, and the lower end of the main rod is connected with a shovel cylinder; an annular slot is formed in the upper position of the main rod, a limit cylinder matched with the annular slot is arranged in the annular slot, and a clamping ring is arranged at the top end of the push-up rod; and the outer diameter of the clamping ring is greater than the inner diameter of a circular open slot, the diameter of the pushing block is matched with the inner diameter of the shovel cylinder, and theouter diameter of the clamping block is greater than the inner diameter of the circular open slot and the inner diameter of a hollow cylindrical slot. Compared with the prior art, the coal slime sampling shovel has the advantages that the sampling shovel is simple and reasonable in structure and convenient to operate, and columnar coal slime not prone to being scattered and broken can be obtained;by adjusting the position of the limit cylinder relative to the main rod, a coal slime sample in a certain volume can be obtained; and the obtained sample is stable in quality, and therefore inspection quality can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of coal slime sampling, in particular to a coal slime sampling shovel with adjustable collection volume. Background technique [0002] With the development of my country's industrial science and technology, the depth and breadth of coal processing are developing rapidly, the output of coal slime has increased significantly, and the comprehensive utilization of coal slime has also attracted more and more attention from coal production enterprises and users. Combustion has brought objective economic benefits, but also brought huge environmental benefits to the whole society. Coal slime sampling is a key link in the quality of coal slime. In order to provide a certain quality of coal slime samples, it is necessary to use reasonable Sampling tool, the sampling tool originally designed can achieve a certain weight of slime block in the slime pile, the weight of the slime sample collected by the sampling cylinder of...
