[0008] The chain end and the connecting plate are integrally formed, and a rib plate is fixedly arranged on one side of the connecting portion of the chain end and the connecting plate. The rib plate is symmetrically arranged in two parts.

[0009] As a preferred scheme of the utility model, the scraper connecting piece is in the shape of a T, and is used in combination with a C-shaped scraper.

[0010] As a preferred scheme of the utility model, two rows of connecting holes are symmetrically formed, and each row has three equidistant connecting holes.

[0011] As a preferred scheme of the utility model, the material of the scraper connecting piece is composite nylon PA6.

[0012] As a preferred scheme of the utility model, the middle position of the two rib plates is fixedly installed with a reinforcing plate, and the reinforcing plate is arranged in parallel with the connecting plate.

[0013] As a preferred scheme of the utility model, the outer side of the rib plate is provided with a reinforcing bar, and the reinforcing bars are arranged at equal intervals.

[0014] As a preferred scheme of the utility model, the material of the bolt is stainless steel 316.

[0015] Due to the adoption of the above technical scheme, the utility model has the following beneficial effects:

[0016] The utility model discloses a reinforcing plate and a reinforcing bar are designed, which significantly improve the strength of the connecting piece, effectively avoid the problem of easy breakage, the use of stainless steel 316 bolt and composite nylon PA6 material enhances the corrosion resistance of the connecting piece, prolongs the service life, the T-shaped connecting piece shape is perfectly matched with the C-shaped scraper, the mud scraper system is more stable and reliable, the one-step forming process simplifies the manufacturing process, reduces the cost, and is also beneficial to the later maintenance and replacement. BRIEF DESCRIPTION OF DRAWINGS

[0017] Figure 1 It is a whole structure schematic view of the utility model.

[0018] In the drawing: 1, connecting plate; 2, rib plate; 3, chain end. CONCRETE IMPLEMENTING METHOD

[0019] The technical scheme in the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments.

[0020] Embodiment 1

[0021] As Figure 1 The utility model discloses a connecting piece for a scraper of a chain plate type mud scraper, which comprises a chain end 3, a connecting plate 1 and a rib plate 2, the chain end 3 is fixed on a traction chain through a pin shaft, the connecting plate 1 is used for connecting a scraper, and a connecting hole is arranged on the connecting plate 1 at equal intervals, the connecting hole is fixedly connected with the scraper through a stainless steel 316 bolt; the chain end 3 and the connecting plate 1 are an integral forming structure, and symmetrically two rib plates 2 are fixed on one side of the connecting position, a reinforcing plate is further fixedly installed at the middle position of the two rib plates 2, and the reinforcing plate is arranged in parallel with the connecting plate 1; in addition, three reinforcing bars are arranged at equal intervals on the outer side of the rib plate 2, so as to enhance the strength and stability of the connecting piece,

[0022] The connecting piece is made of composite nylon PA6 material and is formed at one time, has high strength, corrosion resistance and other characteristics, and the 3 pin shaft hole distance of the scraper connecting piece chain end is 125.4mm, which is consistent with the traction chain specification.

[0023] The working principle of the utility model is: in the operation process of the mud scraper, the traction chain drives the connecting piece and the scraper to move together through the chain end 3, and the sludge in the sedimentation tank is scraped and discharged; the connecting plate 1 on the connecting piece is fixedly connected with the scraper through bolts, so that the scraper will not fall off or shake in the moving process, meanwhile, the design of the rib plate 2, the reinforcing plate and the reinforcing rib and other structures enhances the strength and stability of the connecting piece, so that it can bear greater load and impact force, and effectively avoids the problem of easy breaking.

[0024] The components in the text are all general standard components or components known by those skilled in the art, the structure and principle of which can be known by those skilled in the art through technical manuals or through conventional experimental methods, so no more will be recorded here.

[0025] Although the specific embodiments of the utility model have been described in detail above, the utility model is not limited to the above embodiments, and various changes can be made within the knowledge range of ordinary technical personnel in the art without departing from the purpose of the utility model, and modifications or deformations without creative labor are still within the protection range of the utility model.
