Transportation of oil and petroleum products is a priority for the development of the country's economy, therefore, the development of fuel-filling equipment that allows to increase the safety of the operator who controls this equipment, as well as the driver of the tank car who works on the tank – opens (closes) filling hatches, and also manually orients the fuel-filling pipe and lowering (lifting) its in the hatch opening of a tanker truck, is an important task. The article offers a description of a new design of fuel-filling equipment for tankers, which allows automating the process of projecting a filling pipe relative to the hatch of a tanker truck when top-loading petroleum products into tankers and increasing measures to protect the driver and operator. This is achieved by introducing additional hydraulic cylinders into the prototype design, which allow moving the filling pipe in the transverse plane of the hatch, as well as lowering (lifting) the filling pipe into the hatch opening for filling petroleum products. Automation of the process is carried out through the use of a video camera, the image from which is transmitted to the operator's control panel. The image comes from a video camera in real time, and in addition to the transverse movement of the pipe, the depth of movement is controlled by the operator on the monitor.
The article analyzes theoretical and experimental studies of intelligent mechanism designs, considers the advantages of using intelligent mechanisms for agricultural machines in comparison with traditional structural schemes. The principle of operation of an intelligent mechanism presented in the form of two differential drives for agricultural machines is considered. Planetary mechanisms of this type are systems with two or more degrees of freedom in terms of the number of structural connections, therefore, with one leading link, the movement of their driven links is determined by additional external links that may have different physical origins. The paper presents a description and also considers the main advantages of using the developed kinematic scheme of an intelligent mechanism for agricultural machines, which allows for automatic regulation in a wide range of movement speed depending on the load on the working body, the weight of grain on the conveyor belt, the type of soil on which the agricultural machine moves, etc., overload protection, increased productivity due to full engine load. The proposed intelligent mechanism for agricultural machines allows the distribution of torque from a single engine, and there is also no need to install a set of sensors and a control unit.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
