Изобретение относитс к землеройной технике и предназначено дл отрывки траншей и котлованов различного назначени .The invention relates to earthmoving machinery and is intended for fragments of trenches and trenches for various purposes.

Известен рабочий орган, содержащий ротор с ков1::ами, которые снабжены боковыми выдвижными стенкс1ми в виде зубьев.A working tool is known that contains a rotor with cov1 :: ami, which are provided with side retractable walls in the form of teeth.

Зубь в зоне копани грунта своей тыльной частью вход т в контакт с копиром неподвижной рамы. Возможен вариант передачи копиру и боковым зубь м вибрационного направленного воздействи . Выдвижные боковые зубь производ т в забое прорези, а основные режущие кромки идущих вслед за ними ковшей скалывают грунт Ll.The tooth in the soil digging zone, with its back part, comes into contact with the cam of the fixed frame. It is possible to transfer the copier and the side teeth of the vibration directional influence. The retractable side teeth are cut in the face, and the main cutting edges of the buckets following behind them break the soil Ll.

Недостатком данной конструкции, вл етс то, что.она не допускает применени операции подрезани в центральной часЛ разрабатываемой выемки.The disadvantage of this construction is that it does not allow the use of a cutting operation in the central part of the excavation.

Известен также рабочий орган траншеекопател , содержащий раму с ковшовыми роторами и фрезы, резцы которых в передней части расположены с опережением зубьев ковшей 2}.Also known working body trenchers, containing a frame with bucket rotors and cutters, the cutters of which in the front are located ahead of the teeth of the buckets 2}.

Однако диаметр фрез по койструктивным соображени м больше диаметра выступов ковшей ротора, поэтому этот рабочий орган не приспособлен дл However, the diameter of the mills for muscular considerations is larger than the diameter of the projections of the rotor’s buckets, therefore this tool is not adapted for

рыть траншей и котлованов с ровным дном.dig trenches and trenches with a flat bottom.

Фрезы и ковшевой ротор скреплены между собой и оборудованны единым приводом, допускающим разработку грунта лишь статическим резанием, что ведет к значительной энергоемкости разработки грунта.The cutters and the bucket rotor are fastened together and are equipped with a single drive, allowing the development of the soil only by static cutting, which leads to a significant energy intensity of the development of the soil.

Цель изобретени - снижение энер10 гоемкости разработки грунтов.The purpose of the invention is to reduce the energy capacity of soil excavation.

Эта цель достигаетс тем, что в рабочем органе траншеекопател , содержащем раму с ковшовыми роторами и фрезы, резцы которых в передней This goal is achieved by the fact that in the working body of a trencher, containing a frame with bucket rotors and cutters, the cutters of which are in the front

15 части расположены с опережением зубьев ковшей, фрезы снабЖ|ены приводом крутильных колебаний и упругими элементами, прикрепленньоми к раме и фрезам, при этом фрезы свободно уста20 новлены относительно ротора.15 parts are positioned ahead of the teeth of the buckets, the cutters are equipped with a drive of torsional vibrations and elastic elements attached to the frame and cutters, while the cutters are freely mounted relative to the rotor.

.На фиЕ.. 1 показан рабочий органj на фиг. 2 - сечение А-А на фиг.1.. FIG. 1 shows the operating member j in FIG. 2 is a section A-A in FIG.

Рабочий орган содержит раму 1, несущую на своей .т ге привод 2 кру25 тильных колебаний, подгребной донный нож 3 с опорным катком 4, опорные ролики 5, законтактИрованные с ковшовым ротором 6, оборудованным параллельно расположенными на нем р дами ковшей 7, р промежутках междуThe working body contains a frame 1, carrying on its t drive 2 of the crucible vibrations, a bottom rake knife 3 with a supporting roller 4, supporting rollers 5, contacted with a bucket rotor 6, equipped in parallel with rows of buckets 7 located on it, between

Claims

30 which are located disk milling cutters 8, equipped with incisors 9, and a mechanism for turning the rotor 6 (not shown in the drawing). Disk milling cutters 8 are set relative to the rotor 6 freely crescent-shaped, serve as common side walls, for buckets 7, fastened between the upper and lower transverse struts 1 and 10 and connected to the driven link of the vibrator 2 by means of a hinged lever. 12. The lower cutters 9 of the cutters are installed at the level of the teeth of the buckets 7. The disk cutters 8 are connected to the fixed frame 1 via elastic elements 13. The working member works as follows. From the actuator 2, the swinging movement 12 is transmitted via a hinged-rotated mechanism 12 to disk milling cutters 8, which with their cutters 9 cut gaps in the ground as the base machine moves. The cutters 9 on the cutters 8 are installed so that the soil they destroy is squeezed out in the direction of the buckets 7 which, at esm, develop the soil with a large chip, and then transport it to the unloading area. The development of the soil proposed by the working body is less energy-intensive. The bottom of the trench is flat. Claim 1. Worker body of a trencher containing a frame with bucket rotors and cutters, the cutters of which in the front end are arranged ahead of the teeth of the buckets, characterized in to the frame and cutters, with the cutters freely mounted relative to the rotor. 2. Worker body pop. 1, about tl, which is due to the fact that the cutters are sickle-shaped. 3. The working body according to claim 1, of which is that the cutters are connected with the drive of torsional vibrations by means of a hinged-lever mechanism.
