Problems solved by technology

[0002] At present, the connecting rod mechanism of impact mechanism such as impact mining machine, impact coal shearer or impact excavator is directly connected with the impact head outside the power box. The boxes need to be sealed. Under the frequent reciprocating movement of the connecting rod, the protective cover and the seals are severely worn, causing external dust, water, mineral materials, etc. to enter the box to contaminate the lubricating fluid and rusted parts. After contamination, the lubrication The liquid is easy to cause poor lubrication effect, fast wear of parts, and stop production in severe cases. The installation of the protective cover is complicated and difficult, takes up a lot of space, is easy to be damaged, and is difficult to maintain. In order to solve the above problems, the present invention proposes a connecting rod built-in reciprocating Impact power box

Embodiment 1

[0060] Figure 1 to Figure 2 It is the connecting rod built-in reciprocating impact power box described in Embodiment 1. The connecting rod built-in reciprocating impact power box includes a box body 2, a guide mechanism 4, a link mechanism 5 and an impact head 6, etc., the link mechanism 5 is arranged in the box body 2, and the guide mechanism 4 includes an impact guide 27 and a guide rod. Connector 7 etc., impact guide 27 and guide rod connector 7 integral structure, impact guide 27 includes upper guide rod 3 and lower guide rod 8 etc., upper guide rod 3, lower guide rod 8 etc. are formed by box body 2 Support, the guide rod connector 7 is set in the box body 2, the upper guide rod 3, the lower guide rod 8, etc. are connected through the guide rod connector 7, the upper guide rod 3, the lower guide rod 8 are separately connected with the guide rod connector 7 Or integrated, the link mechanism 5 includes a power impact member 9, etc., the power impact member 9 is hinged with...

Embodiment 2

[0064] Such as image 3 As shown, it is the connecting rod built-in reciprocating impact power box shown in Embodiment 2. The difference from Embodiment 1 is that the guiding mechanism 4 includes guiding rolling bodies 10, etc., and the guiding rolling bodies 10 as shown in the figure are spherical rolling bodies. 11. The spherical rolling body 11 is supported by the box body 2, and the spherical rolling body 11 supports the rolling friction reciprocating motion of the upper guide rod 3 and the lower guide rod 8, etc.

[0065] The guide rolling body can also be an elliptical rolling body or a dumbbell-shaped rolling body or a cylindrical rolling body or a tapered rolling body or a circular rolling body or a roller rolling body or a table-shaped cylindrical rolling body or a table-shaped ball rolling body or a table-shaped rolling body. Drum rolling elements or grooved drum rolling elements or grooved cylindrical rolling elements or grooved ball rolling elements or grooved roll...

Embodiment 3

[0068] Such as Figure 4 to Figure 5 As shown, it is the connecting rod built-in reciprocating impact power box shown in Embodiment 3. The difference from Embodiment 1 is that an anti-damage connecting rod structure 13 is provided between the power impact member 9 and the guide rod connecting member 7, as shown in Figure 4 The shown damage-resistant connecting rod structure 13 is a ball-and-socket type 12 damage-resistant connecting rod structure 13 .

[0069] The anti-damage connecting rod structure can also be an arc-shaped buckle-groove type or a rotating joint head.

[0070] The arc-shaped buckle-groove type includes an arc-shaped convex head, a groove for movable buckling with the arc-shaped convex head, etc., the arc-shaped convex head is arranged on the power impact part or integrated with the power impact part, and The groove for the movable buckle of the head is set on the guide rod connector or integrated with the guide rod connector; or the groove for the movable ...

Abstract

The invention relates to a reciprocating impacting motive power box with a built-in connecting rod. The reciprocating impacting motive power box comprises a box body, a guide mechanism, a connecting rod mechanism, an impacting head and the like, wherein the connecting rod mechanism is arranged in the box body, the guide mechanism comprises an impacting guide element, a guide rod connecting element and the like, the impacting guide element comprises an upper guide rod and a lower guide rod, the upper guide rod and the lower guide rod are supported by the box body, the guide rod connecting element is arranged in the box body, the connecting rod mechanism comprises a motive power impacting element, the motive power impacting element is hinged to the guide rod connecting element, the impacting head is connected with the upper guide rod and the lower guide rod outside the box body, and the connecting rod drives the impacting head to perform the reciprocating impacting through driving the guide rod connecting element to perform reciprocating movement. The direct connection between the motive power impacting element and the impacting head is avoided, the problems that holes and gaps formed between the box body and a section, extending out of the box body to perform reciprocating movement, of the motive power impacting element are difficult to seal, and the like are solved, a protection cover required by the section, extending out of the box body to perform reciprocating movement, of the motive power impacting element is omitted, and the contamination onto a crankshaft and connecting rod mechanism and the like caused by dust, muddy water, mineral residue and the like through holes and gaps between the box body and the crankshaft and connecting rod mechanism is avoided, so better lubrication and protection can be realized on the crankshaft and connecting rod mechanism and the like.

Description

technical field [0001] The invention belongs to the mechanical field, and is especially suitable for a connecting rod built-in reciprocating impact power box in the mining field. Background technique [0002] At present, the connecting rod mechanism of impact mechanism such as impact mining machine, impact coal shearer or impact excavator is directly connected with the impact head outside the power box. The boxes need to be sealed. Under the frequent reciprocating movement of the connecting rod, the protective cover and the seals are severely worn, causing external dust, water, mineral materials, etc. to enter the box to contaminate the lubricating fluid and rusted parts. Liquid is easy to cause poor lubrication effect, fast wear of parts, and stop production in severe cases. The installation of the protective cover is complicated and difficult, takes up a large space, is easy to be damaged, and is difficult to maintain. In order to solve the above problems, the present inve...
