DETAILED DESCRIPTION
[0019] The specific implementation of the present invention will be described below in conjunction with the accompanying drawings.
[0020] like Figure 1 and Figure 2As shown, the present invention mainly includes a hopper 1, and a feeding port 12 is provided on one side of the hopper 1. The cross-sectional dimensions of the hopper 1 decrease from the feeding port 12 to the bottom of the hopper, and the width and depth ratio of the hopper 1 is ≥3:1. The inner end face of the hopper 1 is a streamlined end face with a smooth transition, which can ensure that the hopper 1 is completely dumped and the material does not stick inside the hopper. The hopper 1 has a light weight and is easy to replace. A plurality of raised reinforcing ribs 15 are provided on the front end of the hopper 1 near the feeding port 12, and the plurality of reinforcing ribs 15 are evenly distributed along the width direction of the hopper 1.
[0021] like Figure 1 and Figure 2 As shown, two first supports 4 are fixedly connected to the left and right sides of the back side of the hopper 1 away from the feeding port 12, and two second supports 5 are fixedly connected to the left and right sides of the back side of the hopper 1 close to the feeding port 12.
[0022] like Figure 2 As shown, the first support 4 is rotatably connected to the first end of the first connecting plate 2 of the triangular plate structure through the first rotating shaft 7, and the second end and the third end of the first connecting plate 2 are connected to the link pin of the traction chain 6. The second support 5 is rotatably connected to one end of the second connecting plate 3 through the second rotating shaft 8, and the other end of the second connecting plate 3 is connected to the link pin of the traction chain 6. The traction chain 6 is a maintenance-free die-forged chain structure.
[0023] When working, the traction chain 6 acts as a driving transmission member to drive the reclaiming hopper 1 to move. The first connecting plate 2 of the triangular plate structure cooperates with the second connecting plate 3 to form a relatively stable supporting structure. The reclaiming hopper 1 has a large excavation force to ensure that the reclaiming hopper 1 can overcome the material resistance to realize forward excavation of the material pile and reduce the wear of the material on the reclaiming hopper 1. The back of the reclaiming hopper 1 is connected to the traction chain 6 through the first support 4 and the second support 5, so that the traction chain 6 can avoid contact with the material when the reclaiming hopper 1 is reclaiming, thereby avoiding contact and wear between the chain and the material.
[0024] like Figure 2 As shown, the first rotating shaft 7 is connected to one end of a horizontally arranged retractable first material blocking cover 9, and the other end of the first material blocking cover 9 is connected to the next material hopper 1. The second rotating shaft 8 is connected to one end of a horizontally arranged retractable second material blocking cover 10, and the other end of the second material blocking cover 10 is connected to the previous material hopper 1. The first material blocking cover 9 and the second material blocking cover 10 can prevent the material between the material hoppers 1 from scattering onto the traction chain 6.
[0025] like Figure 1 As shown, a guide roller 11 is provided in the middle of the back of the reclaiming bucket 1. The guide roller 11 can slide in the guide frame of the chain bucket reclaiming head part to ensure that the reclaiming bucket 1 will not deflect when digging and reclaiming materials.
[0026] like Figure 1 and Figure 3As shown, positioning rings 13 are provided at both ends of the first rotating shaft 7 and the second rotating shaft 8 , and the positioning rings 13 are connected to the first rotating shaft 7 and the second rotating shaft 8 through expansion pins 14 .
[0027] The invention has a compact and reasonable structure and is easy to operate. The connecting plate and the traction chain form a relatively stable supporting structure, which reduces the force between the hopper and the material pile, alleviates the wear of the material on the hopper, and realizes the operation mode of the hopper excavating the material pile forward. The traction chain is arranged on the back of the hopper to avoid the scraping and wear between the traction chain and the material, and improves the service life of the traction chain. The hopper is a streamlined design with a wide body and a shallow body, and the material is dumped completely to avoid sticking of the material in the hopper, thereby further improving the comprehensive unloading efficiency of the chain bucket ship unloader.
[0028] The above description is an explanation of the present invention, not a limitation of the present invention. The scope of the present invention is defined in the claims. Any form of modification may be made within the scope of protection of the present invention.
