Rotary type conical mud sampler

Abstract

The invention discloses a rotary type conical mud sampler. The rotary type conical mud sample comprises a power supply (1), a waterproof motor assembly (5), a motor coupler (6), a sampler shaft (12) and a mud storage cavity (8); the power supply (1) is connected with the waterproof motor assembly (5) and supplies power, and a motor shaft of the waterproof motor assembly (5) is connected with the upper end of the sampler shaft (12) through the motor coupler (6) and drives the sampler shaft (12) to rotate; the lower end of the sampler shaft (12) is connected with the mud storage cavity (8), theupper part of the mud storage cavity (8) is a cylindrical cavity, the lower part of the mud storage cavity is a conical cavity with a downward tip, and the cylindrical cavity communicates with the conical cavity; a mud cleaning cabin door (9) is arranged on the side surface of the conical cavity; a plurality of limber holes are arranged on the mud cleaning cabin door (9); the side surface of the conical cavity is provided with a mud cutting port (10) with an outward convex edge, and the inner cavity is provided with a mud cutting port guide baffle (11) in the radial direction. The sampling effect is very ideal, and the sampling success rate is greatly improved. The rotary type conical mud sampler is suitable for collecting sediments in inland water areas such as reservoirs, rivers and lakes. The rotary type conical mud sampler is high in efficiency, stable in effect and capable of separating sediments on site.

Description

technical field [0001] The invention relates to the technical field of mechanical structures, in particular to a rotary cone dredger. Background technique [0002] Surface water resources are an important part of global water resources and the main source of fresh water for human survival. The global surface water reserves are 24,254 trillion cubic meters. Natural rivers and lakes are good for boats and are an important part of land and water transportation. Among them, fish, shrimp, crab, shellfish, lotus, lotus root, water chestnut, gorgon, reed and other aquatic products are also important sources of aquatic products and light industry. [0003] The properties of sediments on the surface of a water body are a comprehensive reflection of hydrology, geology, physics, chemistry, biology and other factors of the water body. They are indispensable scientific research objects for geology, environmental science, ecology and other disciplines. There are very practical applicati...

Problems solved by technology

[0005] The following defects in the prior art: First, in the area of ​​faster flow velocity, due to the large lateral flow velocity, the vertical impulse of the device is largely offset. After the device touches the bottom, due to insufficient vertical impulse, insufficient sinking is likely to occur In some cases, the sampling effect is poor; second, in order to obtain a better sampling effect, the weight of the device is generally very large, which increases the difficulty of operation for the operator.
