Embodiment Construction

[0024] Figure 1~2 It is the best embodiment of the present invention, below in conjunction with attached Figure 1~2 The present invention will be further described.

[0025] A multi-functional crushing head, including a bucket 1, a power bin on the upper part of the bucket 1, a hammer plate 19 on the lower part of the power bin, and a drill bit 3 installed under the hammer plate 19 through a drill rod 2. The power bin includes an oil cylinder 15 in the middle and two Side cylinder 8. The piston rod 16 of the oil cylinder 15 is a tubular structure, and the piston rod 16 is provided with a quick oil return valve. The lower end of the piston rod 16 is fixedly connected with the hammer plate 19, and the piston rod 16 and the hammer plate 19 are provided with a control mechanism that promotes the opening and closing of the quick oil return valve. The quick oil return valve can make the hydraulic oil in the lower cavity of the piston in the cylinder 15 quickly flow to the upper...

Abstract

The invention provides a multifunctional crushing head. The multifunctional crushing head comprises a hopper (1), a power cabin at the upper part of the hopper (1), a hammer plate (19) arranged at the lower part of the power cabin, and a drill bit (3) which is mounted under the hammer plate (19) through a drill rod (2); the power cabin comprises an oil cylinder (15) in the middle and air cylinders (8) on the two sides. The multifunctional crushing head is characterized in that a piston rod (16) of the oil cylinder (15) is in a pipe shape structure; a rapid oil returning valve is arranged on the piston rod (16); the lower end of the piston rod (16) is fixedly connected with the hammer plate (19); the piston rod (16) and the hammer plate (19) are internally provided with control mechanisms for pushing the rapid oil returning valve to be opened and closed. The multifunctional crushing head has large impact force and high energy utilization rate; the drill bit can do reciprocating motion for 180 times each minute and the working efficiency is high; the multifunctional crushing head also can be used as an excavator bucket and is used for cleaning a crushed hard layer.

Description

technical field [0001] The utility model relates to a multifunctional crushing head, which belongs to the technical field of design and manufacture of head equipment of roadheaders, and specifically relates to a multifunctional crushing head. Background technique [0002] Before carrying out earthwork engineering, mining of various mining industries, tunnel excavation, and excavation of permafrost in cold regions, the problem of hard layers must be solved. Blasting with traditional explosives must go through a series of tasks such as building explosives stores, opening roads, drilling, distributing explosives, stopping work before firing, evacuating personnel, and arranging cordons before blasting. Craftsmanship can be loaded. The production efficiency of such production operation is not high, and the safety is not guaranteed. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art an...
