Abstract

The invention provides a double-cylinder hydraulic telescopic excavator shovel head, and relates to the technical field of excavators in mechatronics. The double-cylinder hydraulic telescopic excavator shovel head comprises a first shovel head body and further comprises a second shovel head body and a third shovel head body which are symmetrically connected to the two sides of the first shovel head body. The two ends of the first shovel head body are connected with a first telescopic plate and a second telescopic plate correspondingly. A first guide rail matched with the first telescopic plateis arranged on the side wall of the second shovel head body. The first guide rail is internally provided with a first limiting clamping base used for limiting the first telescopic plate. The side wall of the third shovel head body is provided with a second guide rail matched with the second telescopic plate. The second guide rail is internally provided with a second limiting clamping base used for limiting the second telescopic plate. A hydraulic device for driving the second shovel head body and the third shovel head body to transversely move is further fixed to the back side of the first shovel head body. The double-cylinder hydraulic telescopic excavator shovel head has the beneficial effects that the structure is flexible, the dustproof effect is good and work durability is high.

Description

technical field [0001] The invention belongs to the technical field of excavator shovel heads, and in particular relates to a double-cylinder hydraulic telescopic excavator shovel head. Background technique [0002] With the current urban and rural reconstruction and municipal engineering work, it is necessary to dig ditches of different widths, such as the width required for sewage ditches or the width required for heating pipes. There is no excavator shovel head that can adjust the width on the market. , which leads to laborious and time-consuming work, because if you want to dig a small trench, you need to find a small excavator, and if you want to dig a large trench, you need to find a large excavator. Switching back and forth is very time-consuming and not flexible enough. [0003] A kind of size-adjustable excavator bucket of Chinese patent (application number: CN201720930528.8), comprises a bucket body, and the inner wall of the bottom plate of the bucket body is prov...
