Movable type cantilever material sampling device

Abstract

The invention discloses a movable type cantilever material sampling device. The movable type cantilever material sampling device comprises an automobile chassis, a rotary support, an operation chamber, a first-grade supporting arm and a second-grade supporting arm which are hinged on the automobile chassis, a first-grade oil cylinder hinged between the automobile chassis and the first-grade supporting arm, and a second-grade oil cylinder hinged between the first-grade supporting arm and the second-grade supporting arm, wherein the second-grade supporting arm is further hinged with a third-grade oil cylinder; a piston rod end of the third-grade oil cylinder is hinged with one end of a rocking bar and one end of a connection rod at the same time; the other end of the rocking bar is hinged on the second-grade supporting arm and the other end of the connection rod is hinged on the outer upper corner of a sampling head suspender; the inner upper corner of the sampling head suspender is hinged on the top of the second-grade supporting arm; the sampling head is suspended on the lower end of the sampling head suspender; a four-connection-rod mechanism is composed of the connection rod, the sampling head suspender, the rocking bar and the tail section of the second-grade supporting arm. With the adoption of the sampling head designed by the invention, the large-angle rotation can be realized and the sampling head is convenient to mount and detach; the service life of the sampling device can be prolonged, the use safety is good and the sampling position is accurate.

Description

Technical field [0001] The invention relates to a movable material sampler in the metallurgical industry, in particular to a mobile cantilever material sampler. Background technique [0002] The existing mobile material sampler includes a car chassis with a drive device, a slewing support and operating room in the middle of the car chassis, a support arm hinged on the car chassis, and a final support arm hinged on the support arm. A plurality of oil cylinders hinged between the car chassis, the support arm and the final support arm, a sampling device arranged on the final support arm, the sampling device includes a parallel telescopic device and a sampling head, and the parallel telescopic device is fixed on the final support arm Above, the sampling head is movably connected to the parallel telescopic device, and the parallel telescopic device drives the sampling head to achieve a certain length of telescopic movement along the direction of the final support arm. Although this k...

AI Technical Summary

Problems solved by technology

Although this kind of mobile material sampler can collect materials in a certain direction, it has the following disadvantages: 1. The sampling head can only perform telescopic movement along the final support arm and cannot rotate. The sampling head can rotate as a whole, and its rotation angle is also limited, which cannot meet the actual needs; 2. The installation and disassembly of the sampling head is relatively complicated, and it is extremely inconvenient to replace the sampling head. On the arm, because the slideway is easy to be contaminated with material impurities, the sampling head is easily jammed when it expands and contracts, which affects the service life of the sampling device; 3. The sampler is not equipped with counterweights. When dense), the downspin force of the sampling head will cause a large reaction force on the sampling machine, which will easily lead to unbalanced force on the sampling machine, causing it to move or tilt, causing potential safety hazards; 4. There is no video camera and other video equipment installed on the sampling vehicle The capture device cannot accurately control the sampling depth and direction of the sampling head, and the accuracy of the sampling position is poor
