Description

Technical Field

[0001] The utility model relates to the technical field of excavators, in particular to an excavator frame structure. Background Art

[0002] An excavator, also known as an excavating machine or a backhoe, is an earth-moving machine that uses a bucket to dig materials above or below the surface of the machine and load them into a transport vehicle or unload them to a stockpile. The materials excavated by the excavator are mainly soil, coal, silt, and pre-loosened soil and rock. From the development of construction machinery in recent years, the development of excavators has been relatively fast. Excavators have become one of the most important construction machinery in engineering construction. The central slewing head is an important part connecting the lower frame and the upper frame, and the upper body needs to rotate based on this to work.

[0003] For example, a Chinese patent discloses an excavator frame side plate structure [application number: 201920778884.1], which proposes an excavator frame side plate structure, including a chassis structure and a cleaning structure, the cleaning structure is installed and fixed on the side surface of the chassis structure, the chassis structure includes a frame, a track, an eccentric wheel and a side plate, the track is mounted on both sides of the frame, the side plate is welded and fixed to the inner side of the track on both sides of the frame, and the eccentric wheel is arranged at the center of the frame. In this scheme, a wire brush is provided, and the wire brush head made of stainless steel high elastic steel wire makes the brush head have a strong cleaning effect and a longer service life. It is fast and convenient to clean the dirt inside the concave and convex teeth of the track, and the dirt residue is less. Although the wire brush and the mounting frame are provided, the mounting frame supports the wire brush by being fixed to the surface of the outer plate, so that the wire brush can be effectively fixed to one side of the side plate to clean the dirt on the track.

[0004] However, in this solution, the working environment of the excavator is mostly muddy soil. A large amount of soil is retained at the rotating disc of the excavator. The soil condenses into blocks and accumulates here. It is very troublesome to clean up the large amount of accumulated soil later. At the same time, the excavator needs to turn continuously when working. A large amount of soil retained at the rotating disc will hinder its normal turning, hinder normal work and cause damage to the excavator equipment. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-5The utility model provides a technical solution: an excavator frame structure, including a frame 1, a body 2 is installed in the middle of the frame 1, a bolt 21 is installed at the lower edge of the body 2, a connecting plate 3 is installed at the bolt 21, an arc groove 31 penetrating the outer wall is provided on the connecting plate 3, a support rod 4 is installed below the connecting plate 3, a rectangular groove 41 penetrating the outer wall is provided at the bottom of the support rod 4, a threaded hole 42 penetrating the outer wall is symmetrically provided on the support rod 4, a limiting block 43 is installed on the inner wall of the rectangular groove 41, brackets 5 are installed on both sides of the support rod 4, square blocks 51 are installed at both ends of the bracket 5, and an inclined plate 52 is installed between adjacent square blocks 51, and a soil-breaking block 53 is provided on the outer wall of the inclined plate 52 facing one side, a scraper plate 6 is penetrated on the inner side of the rectangular groove 41, and grooves 61 are symmetrically provided on the scraper plate 6, and a limiting groove 62 is provided between adjacent grooves 61.

[0024] The bolts 21 are installed in a circular shape at the outer wall edge of the body 2, and the bolts 21 here are inserted into the arc groove 31. The body 2 here refers to the rotating component under the cab, where a large amount of soil is piled up. The other equipment structures of the excavator do not belong to the technical points of this case and are therefore not described.

[0025] The arc groove 31 is symmetrically arranged on the connecting plate 3, and the outer wall of the connecting plate 3 is arranged in an arc shape, and the center of the outer wall of the connecting plate 3 and the arc groove 31 are located at the same place. Because of the same center, the connecting plate 3 can be adjusted along the arc groove 31 according to the position of the bolt 21.

[0026] The threaded holes 42 are symmetrically arranged up and down, and the threaded holes 42 are connected to the rectangular groove 41, and the stop blocks 43 are symmetrically distributed. The positions of the threaded holes 42 and the grooves 61 correspond to each other, and the positions of the stop blocks 43 and the stop grooves 62 correspond to each other, and the size of the stop blocks 43 is smaller than the stop grooves 62. When installing the scraper 6 on the support rod 4, the scraper 6 and the support rod 4 can be staggered according to the working environment on site, so that the stop grooves 62 can be moved appropriately along the stop blocks 43. The size of the grooves 61 is larger than the threaded holes 42, so it will not affect the later use of the bolt 21 structure in the middle.

[0027] The square block 51 is provided with a threaded hole 42, and the height of the inclined plate 52 matches the height difference between the support rod 4 and the scraper blade 6. There is a height difference between the support rod 4 and the scraper blade 6, and the square block 51 at one end can be installed on the support rod 4, and the square block 51 at the other end can be installed in the groove 61, so that the bracket 5 can support the scraper blade 6.

[0028] The outer wall of the soil-breaking block 53 protrudes from the inclined plate 52, and the top of the soil-breaking block 53 is in a sharp bulge shape.

[0029] The limiting grooves 62 are symmetrically arranged, and an opening is arranged on the left side of the limiting grooves 62. The left outer wall of the scraper blade 6 is arranged in an arc shape.

[0030] Working principle: When the utility model is used, the scraper blade 6 is inserted into the rectangular groove 41, and the stop block 43 needs to be aligned with one end of the opening of the stop groove 62, and then the scraper blade 6 is allowed to slide in along the stop block 43 through the stop groove 62. The position between the scraper blade 6 and the support rod 4 is adjusted according to the working environment on site, and the distance between the two sides of the scraper blade 6 and the crawler and the frame 1 is properly controlled. During the period when the stop block 43 slides into the stop groove 62, the threaded hole 42 and the groove 61 on the support rod 4 are in an aligned state. At this time, the corresponding bolt 21 is used to fix the stop block 43. Fix, align the threaded holes 42 on the square block 51 with the support rod 4 and the groove 61 respectively and fix them with bolts 21, then align the arc groove 31 with the bolts 21 at the lower edge of the body 2, and similarly fix the connecting plate 3 under the body 2. The connecting plate 3 and the support rod 4 here are fixedly connected. When the excavator is working normally, the soil accumulates on the frame 1. As the body 2 rotates, the scraper 6 also moves. The soil-breaking block 53 breaks the soil to reduce resistance and diverts it to both sides, constantly pushing away the soil blocks on the frame 1 to avoid accumulation here.
