The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] Specific embodiment 1 of the shovel-pushing crushing device involved in this utility model, as follows: Figures 1 to 4 As shown, the shovel-pushing crushing device includes a base 1 that can move left and right and a shovel assembly mounted on the base 1. The shovel assembly has a shovel holder 2. The base 1 is provided with a moving guide rail 3 for the shovel holder 2 to be installed in the left and right direction. The shovel holder 2 is frictionally assembled on the moving guide rail 3. A vertical fixing plate 6 is provided on the right side of the shovel holder 2. A striking seat 7 is detachably connected to the right side of the fixing plate 6. A hydraulic breaker 4 is provided on the base 1 on the right side of the striking seat 7. The chisel 5 of the hydraulic breaker 4 extends to the left and is used to contact the striking seat 7 to drive the striking seat 7 and the shovel holder 2 to vibrate.

[0032] During operation, the shovel-push crushing device is pushed forward. If the electrolyte is relatively soft, there is less resistance when the shovel head contacts the electrolyte for cleaning, and the shovel head directly scrapes off the electrolyte. If the electrolyte is relatively hard, there is greater resistance when the shovel head contacts the electrolyte for cleaning, and the shovel head and shovel holder 2 will move to the right (about 6cm) along the upper moving guide rail 3. When the striking seat 7 moves to the right and contacts the chisel 5, the hydraulic breaker 4 will drive the chisel 5 to strike the striking seat 7 at high frequency and transmit the force to the shovel head, causing the shovel head to generate impact vibration force to clean the electrolyte with higher hardness.

[0033] In order to realize the limiting detachable assembly of the beating seat 7 and the fixed plate 6, specifically, a rectangular groove is formed on the right side wall of the shovel holder 2, the fixed plate 6 is fixed on the left groove wall of the rectangular groove, the left side plate surface of the fixed plate 6 is provided with the upper and lower spaced connection convex edges, which are attached to the upper and lower plate surfaces of the shovel holder 2, and the fixed connection with the shovel holder 2 is realized by welding, the right side plate surface of the fixed plate 6 is provided with the cross key groove 12 for fiber insertion with the beating seat 7; on the contrary, the beating seat 7 is a rectangular block structure as a whole, the left side plate surface is provided with the cross key 13 matched with the cross key groove 12, and the right side plate surface is used for contact impact with the drill rod 5; the screw nut structure 14 is connected between the edge corner positions of the beating seat 7 and the fixed plate 6.

[0034] In order to avoid the beating seat 7 from the fixed plate 6 due to high load and high frequency vibration, which affects the limiting fitting precision of the two. The bottom limiting structure is provided on the right side of the base 1 and / or the shovel holder 2, which is positioned and attached to the bottom side of the beating seat 7 to limit the upward and downward displacement of the beating seat 7, and the side limiting structure is also provided, which is positioned and attached to the two side walls of the beating seat 7 to limit the front and rear displacement of the beating seat 7.

[0035] Specifically, in this embodiment, in order to facilitate installation and ensure the compactness of the structure, the bottom limiting structure includes a limiting bracket provided on the base 1, and the upper plate surface of the limiting bracket is slidably attached to the bottom side wall of the beating seat 7. The limiting bracket includes a bracket body 8 and a wear plate 9 provided on the bracket body 8, and the upper plate surface of the wear plate 9 is slidably and frictionally attached to the beating seat 7. The bracket body 8 is a rectangular frame structure as a whole, and the wear plate 9 is fixed on the upper end surface of the bracket body 8.

[0036] In addition, in order to facilitate assembly and replacement of the wear plate 9 in the later period, the bracket body 8 is detachably fixed on the base 1, and the wear plate 9 is detachably fixed on the bracket body 8. The bracket body 8 is connected with the base 1 by bolts, and the wear plate 9 is connected with the bracket body 8 by bolts.

[0037] In order to realize the limiting of the front and rear direction of the beating seat 7, the upper plate surface of the limiting bracket is provided with the left and right extending U-shaped limiting groove 10, the front and rear two side walls of the U-shaped limiting groove 10 constitute the side limiting structure, and the bottom wall of the U-shaped limiting groove 10 constitutes the bottom limiting structure.

[0038] In actual operation, the bottom limiting bracket can limit the vertical movement of the striking base 7 through the sliding friction between the wear-resistant plate 9 and the bottom side wall of the striking base 7; while the two side walls of the U-shaped limiting groove 10 limit the front and rear sides of the striking base 7 in the front and rear directions; even if the connecting bolts on the striking base 7 are slightly loose, it can effectively ensure that the mating surface of the cross keyway 12 between the striking base 7 and the fixing plate 6 will not be laterally dislodged and offset, thus preventing the striking base 7 and the fixing plate 6 from being damaged by impact, ensuring the accuracy of the left and right direction of the two, improving the stability of the equipment, making it highly practical, and with a simple overall structure and easy installation.

[0039] Example 2: The difference from Example 1 is that, as Figure 5 As shown, a side limiting structure is provided on the blade holder 2. A rectangular groove is provided on the right side of the blade holder 2. The fixing plate 6 is fixed on the left side wall of the rectangular groove. Limiting sections 11 are provided on the front and rear sides of the rectangular groove.
