Problems solved by technology

The traditional side wall pilot pit excavation method is a combination of ordinary excavator excavation and manual chiseling. This excavation method requires manual work for a long time on the bare soil excavation surface without any support, and the progress is slow. , more dangerous
Due to the large bucket of ordinary excavators, the space of the pilot pit on the side wall is small, and the excavator can not excavate in place at the corners of the pilot pit, and it takes a lot of time and labor to repair and chisel

Embodiment 1

[0027] Embodiment one: if Figure 1 to Figure 2 , Figure 4 to Figure 11 As shown, an excavator bucket with a scraper includes a bucket bottom plate 1, a bucket side plate 2 and a scraper 3; one end of the scraper 3 is detachably connected to the bucket side plate 2 through a connecting device, and the other end is connected to the bucket bottom plate 1 side extends and exceeds the bottom plate 1 of the bucket; the connecting device includes a first fixed flap 21 and a second fixed flap 22 which are fixed on the side plate 2 of the bucket and are parallel to each other. The plate 21 runs through, and a sealing plate 23 is provided at one end of the second fixed folded plate 22; The spacing is 300mm, and they are all made of the same common Q235 steel plate, the inner and outer surfaces are rough to increase the friction with the scraper 3, and the thickness is 20mm; the first fixed folding plate 21 is close to the side of the bucket bottom plate 1, Weld parallel to the botto...

Embodiment 2

[0030] Embodiment two: if image 3As shown, the difference between the second embodiment and the first embodiment is that another connecting device is used to replace the connecting device of the first embodiment; the connecting device includes a first telescopic sleeve 41 connecting the scraper 3 and the bucket side plate 2 and the second telescopic sleeve 42 that is arranged obliquely and connects the outer wall of the first telescopic sleeve 41 and the bucket side plate 2; the first telescopic sleeve 41 is arranged perpendicular to the bucket side plate 2; the second telescopic sleeve 42 is arranged at the A telescopic sleeve 41 is away from the side of the bucket bottom plate 1; the first telescopic sleeve 41 and the second telescopic sleeve 42 are both provided with springs or filled with elastic materials; When the force is too large, it can be stretched and buffered to prevent the scraper 3 from breaking, and the second telescopic sleeve 42 can support the pressure on t...

Abstract

The invention discloses a standardbucket with scraper. The standardbucket comprises a digging bucket bottom, a scoop side panel and a scraper; an end of the scraper is connected disassembly with the scraper through a connecting device. The other end extends to the digging bucket bottom and exceeds it. The side of the scraper is paralleled with the scoop side panel; the scrapper needn't to be repaired and digged by manual aid. The device improves efficiency, particularly, the safety of tunnel soil section construction.

Description

technical field [0001] The invention relates to an excavator bucket with a scraper, which belongs to the field of construction machinery. Background technique [0002] The excavation of the soft surrounding rock section of the tunnel is generally carried out by the double-side pilot pit method. To ensure construction safety, the double-side pilot pit is generally used for excavation during construction. The excavation surface is approximately triangular and the construction space is narrow. The traditional side wall pilot pit excavation method is a combination of ordinary excavator excavation and manual chiseling. This excavation method requires manual work for a long time on the bare soil excavation surface without any support, and the progress is slow. , greater risk. Due to the large bucket of ordinary excavators and the narrow space of the pilot pit on the side wall, the excavator can not excavate in place at the corners of the pilot pit, and it takes a lot of time and ...
