Description
(54) УСТРОЙСТВО ДЛЯ УПРАВЛЕНИЯ ИСПОЛНИТЕЛЬНЫМ ОРГАНОМ ГОРНОГО КОМБАЙНА(54) DEVICE FOR MANAGING THE EXECUTIVE BODY OF THE MOUNTAIN COMBINE
1one
Изобретение относитс к устройствам дл управлени исполнительными органами горных комбайнов и может быть использовано при выемке полезных ископаемых.The invention relates to devices for controlling the executive bodies of mining combines and can be used in the excavation of minerals.
Известны исполнительные органы горных комбайнов, включающие режущий диск, от- 5 рывник, гидроцилиндр с рабочей и сливной полост ми, пульсатор давлени , состо щий из импульсного клапана и аккумул тора, маслопроводы рабочей и сливной полостей гидроцилиндра, маслостанцию 1.Known executive bodies of mining combines, including a cutting disc, an opener, a hydraulic cylinder with a working and drain cavities, a pressure pulsator consisting of a pulse valve and an accumulator, oil lines of the working and drain cavities of the hydraulic cylinder, an oil station 1.
Недостатком устройства управлени указанного исполнительного органа вл ютс большие потери рабочей жидкости из аккумул тора после отрыва подрезанного целика .A disadvantage of the control device of the said executive body is the large losses of the working fluid from the battery after the cut-off rear sight has been torn off.
Наиболее близко к изобретению устройст- 5 во дл управлени исполнительного органа горного комбайна, включающее гидроцилиндр с рабочей и сливной полост ми, пульсатор давлени , содержащий импульсный клапан и аккумул тор, маслопроводы рабо- 20 чей и сливной полостей гидроцилиндра и маслостанцию. В период переключени импульсного клапана на зар дку аккумул тора закрытию порщн клапана преп тствуетClosest to the invention is a device for controlling the executive body of a mining combine, which includes a hydraulic cylinder with a working and drain cavities, a pressure pulsator containing a pulse valve and a battery, the oil cylinders of the hydraulic cylinder and the oil station. During the switching period of the pulse valve for battery charging, closing the valve of the valve prevents
скоростной напор истекающей на слив рабочей жидкости из аккумул тора 2.the velocity head flowing into the discharge of the working fluid from the battery 2.
Недостатком известного исполнительного органа вл етс снижение КПД пульсатора за счет потерь рабочей жидкости из аккумул тора в период переключени импульсного клапана на зар дку аккумул тора после осуществлени отрыва подрезанного целика. Кроме того, закрытию импульсного клапана пульсатора давлени в период переключени этого клапана на зар дку преп тствует скоростной напор рабочей жидкости из аккумул тора. Это удлин ет процесс закрыти импульсного клапана и обусловливает снижение КПД пульсатора за счет потерь сжатой жидкости и снижение эффективности работы устройства.A disadvantage of the known executive body is a decrease in the efficiency of the pulsator due to the loss of the working fluid from the battery during the switching period of the pulse valve to battery charging after the cut off of the trimmed tube has been removed. In addition, the closure of the pulsator pressure pulse valve during the switching period of this valve to charging is prevented by the velocity of the working fluid from the battery. This prolongs the process of closing the pulse valve and causes a decrease in the efficiency of the pulsator due to the loss of compressed fluid and a decrease in the efficiency of the device.
Цель изобретени - повышение эффективности работы за счет уменьшени потерь рабочей жидкости из аккумул тора в период переключени импульсного клапана на зар дку аккумул тора.The purpose of the invention is to increase the operating efficiency by reducing the loss of working fluid from the battery during the switching period of the pulse valve to charge the battery.
