Abstract

The invention provides a multifunctional integrated bulk material characteristic testing device which comprises a lead screw module used for fixing and precisely lifting a material collecting barrel, wherein the lead screw module comprises a sliding block, a coupler, a lead screw, a sliding rod, a linear guide rail and a motor; a material collecting barrel, wherein a gate, a separation blade and a bolt are associated with the material collecting barrel; a material frame, wherein a sliding guide rail, a sliding plate, an upper cover plate and a U-shaped clamping groove are associated with the material frame; a lifting oil cylinder, wherein a tension meter, a pulley, a clamping groove, a sliding flat plate, a supporting rotating frame, a vibration platform and a stacking flat plate are further included in association with the lifting oil cylinder, and the tension meter is connected with the sliding flat plate through a rope wound on the pulley connected to a buckle; and a material barrel which is designed outside the device and is a cylindrical barrel with the bottom and the top completely penetrating through, and is placed on the material stacking flat plate when needing to be used. The integrated device is simple in principle, easy and convenient to install and convenient to use, various characteristics of bulk materials can be measured at the same time, the defect that a traditional testing device is single in function is overcome, and the problems that a material collecting barrel needs to be moved manually and is inaccurate in traditional lifting are solved through a provided lead screw module.

Description

technical field [0001] The invention relates to a port machinery measuring device, in particular to a bulk material testing device for continuous handling equipment. Background technique [0002] With the continuous development of economic globalization, global trade exchanges are quite frequent, and the proportion of my country's port machinery field in the international arena is also quite large. Compared with air and railway transportation, ocean transportation has become the most important mode of transportation in international trade because of its advantages such as large volume, low cost, and waterways extending in all directions. With the increase of international trade volume, the transportation volume of large-scale handling equipment in port machinery, such as screw ship unloader, is also increasing. When the ship unloader transports the material, it is a very critical step for the ship unloader to measure the characteristics of the material in advance, such as t...
