Technical Field

[0001] This utility model relates to a bucket protection mechanism, a bucket, and an excavator loader, belonging to the field of engineering machinery technology. Background Technology

[0002] As a multi-functional small construction machine, excavation is an important operation for backhoe loaders. During excavation, the backhoe loader needs to be supported by outriggers and a bucket to ensure stability. Because the backhoe loader's loading function needs to be guaranteed, the bucket is equipped with a shovel tooth assembly. When the bucket is supported, the bucket's main blade and shovel teeth can cause some damage to the working surface.

[0003] While field construction does not have high requirements for ground protection, it is difficult to balance operational stability and ground protection when it comes to urban road construction, landscaping, indoor construction, and other projects that require higher ground protection. Often, the ground where the machine is stopped is damaged after the work is completed, and the damaged ground needs to be repaired, which seriously affects the machine's working efficiency and effectiveness.

[0006] Furthermore, the protective pad assembly includes a protective pad, and protective pad brackets are provided on the upper side of the protective pad. The protective pad brackets are used for detachable connection with the bucket, and pull rings are provided on the upper part of the protective pad located between the protective pad brackets.

[0007] Furthermore, the protective pad bracket is provided with a slot, and the back of the bucket is provided with a support member, the support member and the main blade of the bucket being adapted to the slot.

[0008] Furthermore, it also includes a cable locking member and a cable assembly for securing the protective pad assembly. The cable locking member is located below the back of the bucket and includes a cable fixing bracket and a handle. The cable fixing bracket has a through hole, and a hinge pin passes through the through hole. The handle is sleeved on the hinge pin. The cable assembly includes a cable and a hook connector. The hook connector is connected to one end of the cable, and the other end of the cable is connected to the end of the handle. The hook connector is connected to a protective pad.

[0009] Furthermore, the hook connector is connected to the protective pad via a cable fastener, which is located above the protective pad on the side opposite to the pull ring.

[0010] Furthermore, the cable locking component also includes a limiting component, which has an upper locking position and a lower locking position. The handle is limited by a locking pin inserted in the upper locking position and the lower locking position.

[0011] Secondly, this utility model also provides a bucket, which includes the bucket protection mechanism described in any one of the first aspects.

[0012] Thirdly, this utility model also provides an excavator loader, which includes a bucket as described in the second aspect.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: When the excavator loader is in the loading state, the protective pad assembly is attached to the support on the back of the bucket, which can prevent it from having an adverse effect on the loading operation. When the excavator loader is in the digging operation, the protective pad assembly is attached to the main cutter plate of the bucket, which can effectively protect the construction and parking ground during the digging operation, prevent the operation from damaging the site, and improve the environmental adaptability of the excavator loader.

Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention. Example 1

[0016] like Figure 1 As shown, this embodiment of the utility model provides a bucket protection mechanism, including a protective pad assembly 4. The protective pad assembly 4 is detachably connected to the bucket 1, meaning that the protective pad assembly 4 is located at different positions on the bucket 1 when the bucket 1 is in different working states. Specifically, when the bucket 1 is in the loading operation state, the protective pad assembly 4 is hung on the support member 2 on the back of the bucket 1. In this embodiment, there are two support members, which are respectively located on both sides of the back of the bucket 1. When the bucket 1 is in the digging operation state, the protective pad assembly 4 is hung on the main cutter plate of the bucket 1.

[0017] like Figure 4 As shown, the protective pad assembly 4 includes a protective pad 44, and protective pad supports 41 are provided on both sides of the upper surface of the protective pad 44. In this embodiment, each protective pad support 41 is provided with a slot 411, which is adapted to the main blade of the support member 2 and the bucket 1, and the protective pad assembly 4 can be inserted into the support member 2 and the main blade of the bucket 1 through the slot 411. A pull ring 43 is also provided on the upper part of the protective pad 44 located between the two protective pad supports 41, which facilitates manual disassembly of the protective pad assembly 4.

[0018] In some embodiments, to further ensure a secure connection between the protective pad assembly 4 and the bucket 1, a cable locking member 3 and a cable assembly 5 are also included, combined with... Figure 5 The cable locking component 3 includes a cable fixing bracket 33 and a handle 31. In this embodiment, the cable fixing bracket 33 is provided with three pairs of through holes, and the positional relationship of the three pairs of through holes forms a triangle. A hinge pin 32 is inserted into one pair of through holes, and the handle 31 is sleeved on the hinge pin 32. The other two pairs of through holes are the upper locking position and the lower locking position, respectively, which are used to insert locking pins 34. The locking pins 34 are used to limit the position of the handle 31.

[0019] The cable assembly 5 includes a cable 51 and a connector 52. The connector 52 is connected to one end of the cable 51, and the other end of the cable 51 is connected to the end of the handle 31. In this embodiment, a round hole is provided at the end of the handle 31 to fix the end of the cable 51. A cable fixing member 42 is provided on the upper surface of the protective pad 44 on the side opposite to the pull ring 43, and the connector 52 is connected to the cable fixing member 42.

[0020] The working principle of this utility model is as follows: Combination Figure 1 When the bucket 1 is in the loading operation state, the protective pad assembly 4 is attached to the back of the bucket 1. Specifically, the slot 411 of the protective pad bracket 41 is inserted into the support 2.

[0021] Then, manipulate the handle 31 upwards to connect the hook connector 52 to the cable fixing member 42, and insert the locking pin 34 into the lower locking position, thereby limiting the position of the handle 31 below the lower locking position.

[0022] When the bucket 1 is in the digging operation state, the protective pad assembly 4 is removed from the support 2 on the back of the bucket 1 using the pull ring 43, and the protective pad assembly 4 is attached to the main cutter plate of the bucket 1.

[0023] Then, operate the handle 31 downwards to connect the hook connector 52 to the cable fixing member 42, and insert the locking pin 34 into the upper locking position, thereby limiting the position of the handle 31 to the upper locking position. Example 2
