Description

Technical Field

[0001] This utility model relates to a protective structure, specifically a protective structure for the pusher blade of a small excavator that integrates pusher and excavator, belonging to the field of pusher blade protection technology. Background Technology

[0002] The pusher-excavator is a multi-functional engineering machine that integrates excavation and bulldozing functions. It has the advantages of easy operation, high flexibility, and saving time and costs. It is widely used in earthwork engineering, special site construction, river dredging and other fields. The current pusher-excavator structure is usually with the excavating shovel on the front and the pusher shovel on the rear. The excavating shovel can rotate. When the excavating shovel is used, the pusher shovel is lowered, which also plays a role in auxiliary support. When the pusher shovel is in use, it pushes the object through the lower cutting edge. However, when the pusher shovel is not in use or when it is lowered for support, the cutting edge is prone to collision, which can cause damage and chipping, affecting subsequent use. Currently, the cutting edge of the pusher shovel is mostly exposed. In order to protect it, a structure for protecting the cutting edge of the pusher shovel is proposed. Utility Model Content

[0003] The purpose of this utility model is to provide a protective structure for the pusher blade of a small excavator that integrates pushing and digging, in order to solve the above problems. It can protect the blade edge when the pusher blade is not in use, and is easy to install and disassemble. When the pusher blade is in use, the upper end of the pusher blade is raised to improve the bulldozing effect.

[0004] This utility model achieves the above-mentioned objective through the following technical solution: a protective structure for the pusher blade of a mini excavator integrating pusher and digger, comprising a pusher blade and a protective sleeve. Limiting rings are fixedly installed on both sides of the upper end of the pusher blade, and square blind holes are opened on both sides of the lower end of the pusher blade. Connecting plates are fixedly installed on both sides of the protective sleeve, and the inner dimensions of the connecting plates match those of the limiting rings. A square pin is inserted into the connecting plate, and the square pin is inserted into the square blind hole. When the pusher blade is not in use, the protective sleeve is installed... On the underside of the pusher, the square pin passes through the connecting plate and is inserted into the square blind hole, so that the protective sleeve covers the cutting edge of the pusher and prevents damage when the pusher is lowered to support the excavator. When the pusher needs to be used, the square pin is pulled out and the protective sleeve is detached from the lower end of the pusher, so that the protective sleeve is inserted into the limiting ring at the upper end of the pusher through the connecting plate, thereby increasing the height of the pusher and thus increasing the pushing capacity of the pusher.

[0005] Preferably, one side of the protective sleeve has a notch that matches the blade edge of the pusher, and a rubber pad is inlaid inside the notch. When protecting the blade edge, the lower blade edge of the pusher is located inside the rubber pad, which not only covers the blade edge but also protects it, preventing damage to the blade edge caused by external impact.

[0006] Preferably, the connecting plate has a square through hole, and the square pin extends through the square through hole into the interior of the square blind hole. When the protective sleeve protects the pusher, the square through hole and the square blind hole are aligned, and one end of the square pin is inserted through the square through hole into the interior of the square blind hole, which facilitates fixing the protective sleeve and makes operation easier.

[0007] Preferably, a magnetic ring is embedded in the connecting plate on one side of the square through hole, and one end of the square pin is magnetically attracted to the magnetic ring. After the square pin is inserted, one end of the square pin is magnetically attracted to the magnetic ring, thereby avoiding the risk of the square pin coming out of the square blind hole.

[0008] Preferably, a circular pin is inserted into the connecting plate. The circular pin passes through the square through hole and is inserted into the square pin. After the square pin is inserted, the circular pin fixes the connecting plate and the square pin, further improving the stability of the square pin.

[0009] Preferably, the circular pin has a T-shaped structure, and an elastic metal wire is inserted into the lower end of the circular pin. The elastic metal wire has a Z-shaped structure, and a circular hole is opened at the lower end of the circular pin. The elastic metal wire is inserted into the inside of the circular hole. After the circular pin is inserted, the stability of the circular pin is improved by the elastic metal wire.

[0010] Preferably, the connecting plate has a circular hole that passes through the square through hole, and the circular pin is inserted into the inside of the circular hole, which facilitates the insertion of the circular pin.

[0011] Preferably, the square pin has a through hole, and the middle position of the circular pin is located inside the through hole, which facilitates limiting the square pin and improves the stability of the protective sleeve when connected to the lower end of the pusher.

[0012] The beneficial effects of this utility model are: by adopting a protective sleeve with pin connections, it is easy to install and disassemble, and convenient to operate. When the pusher is not in use, the protective sleeve is installed at the cutting edge of the lower end of the pusher to protect the cutting edge and avoid chipping damage. When the pusher is in use, the protective sleeve is installed on the limiting ring to raise the upper end of the pusher, thereby increasing the pushing force when pushing soil, making it easy to use and convenient to protect the pusher.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-6As shown, a protective structure for the pusher blade of a mini excavator integrating pusher and excavator includes a pusher blade 1 and a protective sleeve 2. Limiting rings 3 are fixedly installed on both sides of the upper end of the pusher blade 1, and square blind holes 4 are opened on both sides of the lower end of the pusher blade 1. Connecting plates 5 are fixedly installed on both sides of the protective sleeve 2. The inner dimensions of the connecting plates 5 match those of the limiting rings 3. A square pin 6 is inserted into the connecting plate 5, and the square pin 6 is inserted into the square blind hole 4. When the pusher blade 1 is not in use, the protective sleeve 2 is installed on the lower side of the pusher blade 1, and the square pin 6 passes through the connecting plate 5 and is inserted into the square blind hole 4. The inside of the blind hole 4 allows the protective sleeve 2 to cover the cutting edge of the pusher 1, preventing the cutting edge from cracking and being damaged when the pusher 1 is lowered to support the excavator. When the pusher 1 needs to be used, the square pin 6 is pulled out, and the protective sleeve 2 is separated from the lower end of the pusher 1, so that the protective sleeve 2 is inserted into the limiting ring 3 at the upper end of the pusher 1 through the connecting plate 5, increasing the height of the pusher 1 and thus increasing the pushing capacity of the pusher 1. It is convenient to disassemble and assemble, and it is convenient to protect the cutting edge of the pusher 1 when it is not in use.

[0022] One side of the protective sleeve 2 has a notch 7 that matches the cutting edge of the pusher 1, and a rubber pad 8 is inlaid inside the notch 7. When the protective sleeve 2 protects the lower cutting edge of the pusher 1, the lower cutting edge of the pusher 1 is located inside the rubber pad 8, which not only covers the cutting edge but also protects it, preventing damage to the cutting edge from external impacts. The connecting plate 5 has a square through hole 9, and a square pin 6 extends through the square through hole 9 into the square blind hole 4. Through the square through hole 9, when the protective sleeve 2 protects the pusher 1, the square through hole 9 and the pusher 1 are aligned. Align the square blind holes 4 and insert one end of the square pin 6 through the square through hole 9 into the interior of the square blind hole 4 to fix the connecting plate 5 onto the pusher 1. This facilitates the fixing of the protective sleeve 2 and makes operation easier. A magnetic ring 10 is embedded on one side of the square through hole 9 on the connecting plate 5, and one end of the square pin 6 is magnetically attracted to the magnetic ring 10. After the square pin 6 is inserted, one end of the square pin 6 is magnetically attracted to the magnetic ring 10, thereby avoiding the risk of the square pin 6 coming off the inside of the square blind hole 4 and improving the stability of the connection.

[0023] A circular pin 11 is inserted into the connecting plate 5. The circular pin 11 passes through the square through hole 9 and is inserted into the square pin 6. After the square pin 6 is inserted, the circular pin 11 fixes the connecting plate 5 and the square pin 6, further improving the stability of the square pin 6 and preventing it from coming loose. The circular pin 11 has a T-shaped structure, and an elastic metal wire 12 is inserted into the lower end of the circular pin 11. The elastic metal wire 12 has a Z-shaped structure. A circular hole is opened at the lower end of the circular pin 11, and the elastic metal wire 12 is inserted into the inside of the circular hole. After the circular pin 11 is inserted, one end of the elastic metal wire 12 is in a ring structure and the other end is in a Z-shaped structure, preventing the elastic metal wire 12 from interfering with the connection between the circular pin 11 and the square pin 6. The circular pin 11 is disengaged to improve its stability. A circular hole 13 is provided on the connecting plate 5, which passes through the square through hole 9. The circular pin 11 is inserted into the circular hole 13, which facilitates the insertion of the circular pin 11. When the protective sleeve 2 is installed at the position of the limiting ring 3, the square pin 6 is not used. Instead, the circular pin 11 is inserted into the circular hole 13 and limited by the elastic metal wire 12 to prevent the connecting plates 5 at both ends of the protective sleeve 2 from disengaging from the inside of the limiting ring 3. A through hole 14 is provided on the square pin 6, and the middle position of the circular pin 11 is located inside the through hole 14, which facilitates the limiting of the square pin 6 and improves the stability of the protective sleeve 2 when connected to the lower end of the pusher 1.
