Problems solved by technology

When the above-mentioned sampling device for conveyors samples materials with high moisture content and high viscosity, the materials tend to stick to the rotary sampling head and the chute, making it impossible for all the material samples to flow into the shrinker for screening. In severe cases, the sticky The knotted material will block the sampling device, making the sampling device unable to work
It can be seen that the above-mentioned sampling device for conveyors cannot sample materials with high moisture content and high viscosity

Embodiment Construction

[0016] The present invention will be further described in detail below in conjunction with specific embodiments and accompanying drawings.

[0017] Such as figure 1 , figure 2 As shown, a semi-automatic lifting sampling device includes a frame 1, on which a lifting cylinder 2 with a piston rod that can extend downward is provided, and a lifting cylinder 2 with an opening facing upwards is arranged below the lifting cylinder 2. The sampling box 3 is provided with a crossbeam 31 that is fixed at a distance from the sampling box 3 and does not hinder the entry of the material into the sampling box 3 above the sampling box 3. The top of the lifting cylinder 2 piston rod is fixed to the middle part of the crossbeam 31. In this embodiment Among them, the top of the piston rod of the lifting cylinder 2 is hinged and fixed to the middle part of the beam 31, so that the sampling box 3 can be easily separated from the piston rod of the lifting cylinder 2 when it is damaged and needs t...

Abstract

A semi-automatic lift sampling device is disclosed. The device comprises a rack. The rack is provided with a lift oil cylinder a piston rod of which can protrude downwards. A sampling box is disposed below the lift oil cylinder, and can be driven to move up and down by the lift oil cylinder. The rack is provided with a sampling platform and also provided with a PLC controller. Before sampling, the sampling box is disposed, in a transverse manner, above a thrown material at the tail end of a conveyor, then the PLC controller can allow the lift oil cylinder to drive the sampling box to move downwards, to pass through the thrown material and to stop below the thrown material, the PLC controller can allow the lift oil cylinder to drive the sampling box to move upward so as to collect a material sample, and the material sample in the sampling box can be picked through shoveling by a worker standing on the sampling platform after the sampling box stops at a position above the thrown material. The device can sample materials having high water contents and high viscosity.

Description

technical field [0001] The invention relates to the field of material quality detection equipment, in particular to a sampling device for sampling materials on a conveyor. Background technique [0002] The sampling device is a device that can collect samples from materials at a set frequency. The sampling device for the conveyor is usually installed at the end of the conveyor. The structure of the sampling device for the conveyor includes: a rotary sampling head capable of sampling the materials thrown at the end of the conveyor, and a chute is connected to the lower part of the rotary sampling head , the lower part of the chute is provided with a shrinker for screening the material samples taken by the rotary sampling head. The material samples obtained by the rotary sampling head flow into the shrinker through the chute for screening, and the retained samples screened by the shrinker will be collected in a sample collection device. When the above-mentioned sampling devic...
