Известен ковш экскаватора, включаюищй боковые, переднюю и заднюю стенки н дннще с полостью дл  обогрева ковша.The excavator bucket is known, including the side, front and rear walls and bottom with a cavity for heating the bucket.

Недостатком этого ковша  вл етс  то, что из замкнутой полости дниша пар дл  обогрева ковша не имеет выхода на внутреннюю его поверхность, на которую при работе экскаватора налипает грунт.The disadvantage of this bucket is that the steam for heating the bucket does not have access to its inner surface, from which the soil adheres to the excavator during operation of the excavator from the closed bottom cavity of the bucket.

Цель изобретени  - снижение налинани  грунта на внутреннюю поверхность ковша.The purpose of the invention is to reduce the soil on the inner surface of the bucket.

Дл  этого передн   и задн   стенки предлагаемого ковша вынслнеиы Сполостью, сообшающейс  с полостью дниша, причем внутренн   поверхность ковша, образованна  днишем, передней и задней стенками, выполнена из пористого материала. Кроме того, в полости днпша ковша н в сообшаюшейс  с ней полостн передней и задней стенок установлены перегородкн.For this, the front and rear walls of the proposed ladle are fully with the bottom cavity, the inner surface of the ladle, formed by the bottom, front and rear walls, is made of a porous material. In addition, partition walls are installed in the cavity of the bucket n in the cavity of the front and rear walls, which is connected with it.

На чертеже изображен предлагаемы ковш экскаватора в разрезе.The drawing shows the proposed excavator bucket in the section.

Ковн состоит из передней 1 и задней 2 стенок , и.меюн1их нолость 3, сообшаюшуюс  с полостью 4 дниша 5. Внутренн   поверхность 6 ковша, образованна  дниш,ем, передней н задней Степками, выполнена из пористого матерпела . В полост х 5 и установлены нерегородки 7 дл  получени  замкнутых камер с разным давлением подачи газа, завис шим от внешнего давлеии  по длине рабочей поверхности .The wicker consists of the front 1 and rear 2 walls, and the bottom 3, which communicates with the cavity 4 days 5. The inner surface 6 of the bucket, formed by the bottom, is the front and rear Steps, made of porous mat. In cavities 5 and non-enclosures 7 are installed to obtain closed chambers with different gas supply pressures, depending on external pressure along the length of the working surface.

Нри заполненнн н выгрузке ковша включаетс  насос н в полости 3 и 4 подаетс  жидкость или газ, которые далее попадают через мнкропоры на рабочую поверхность, образу  на ней промежуточный слой, преп тствуюш.ий прилипанию грунта и уменьн1аюш,ий трение прп копании и выгрузке.When the bucket is unloaded, the pump is turned on and cavities 3 and 4 are supplied with liquid or gas, which then fall through the micro-pores on the working surface, forming an intermediate layer on it, preventing soil from sticking and reducing the friction of the soil and unloading.

Различное давление жидкости или газа в образованных перегородками 7 камерах полостей 3 II 4 обеспечиваетс  различным сечением проходных отверстий в перегородках, через которые жидкость или газ перетекают из одной камеры, ограниченной перегородками, в другую.The different pressure of the liquid or gas in the cavities 3 II 4 formed by the partitions 7 is provided by a different cross section of the apertures in the partitions through which the liquid or gas flows from one chamber limited by partitions to the other.

Предмет изобретени Subject invention

1.Ковш экскаватора, включаюшпй боковые , переднюю н заднюю стенки и днише с полостью, отличающийс  тем, что, с целью снижени  иалииаии  грунта на внутреннюю поверхность ковша, нередн   н задн   стенки ковша имеют полость, сообн1,аюшуюс  с полостью днища, причем внутренн   поверхность ковша, образованна  днишем. передней и задней стенками, выполнена из пористого матернала.1. Excavator bucket, including the side, front and rear walls and the bottom of the cavity, characterized in that, in order to reduce soil on the inside surface of the bucket, occasionally on the rear wall of the bucket have a cavity, adjacent to the bottom cavity, and the inside surface bucket formed by the bottom. front and rear walls, made of porous material.

2.Ковш но п. 1, отличающийс  тем, что в полости дниша ковша, а также в сообшаюи ейс  с ней полостн передней и задней стенок установлены перегородкн.2. The bucket of claim 1, characterized in that the partition of the front and rear walls are installed in the cavity of the bottom of the bucket, as well as in the front and rear walls.
