Description

Technical Field

[0001] The utility model belongs to the technical field of excavator buckets, and in particular relates to an excavator bucket structure. Background Art

[0002] Excavators are one of the main types of construction machinery. Buckets are an important part of the excavator's working device, and the quality of their structure will directly affect the quality and efficiency of the entire excavator's work.

[0003] At present, commonly used buckets include a bucket bottom plate and side plates on both sides of the bucket bottom plate. The existing bucket side plates are all straight plates. When the excavator is excavating materials, the bucket side plates are in contact with the materials, and the materials inside and outside the side plates will generate resistance to the bucket side plates, thereby causing serious wear on the side plate structure. The large resistance also makes the excavator digging more laborious, increases the excavator's fuel consumption, and causes unnecessary resource loss. Utility Model Content

[0004] In view of the defects or shortcomings in the prior art, the utility model provides an excavator bucket structure, which can reduce the resistance of the material to the side plate during the excavation process of the excavator, thereby reducing the wear of the side plate.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

Two side plates are provided, and the two side plates are symmetrically fixed on both sides of the bucket bottom plate and are perpendicular to the bucket bottom plate. The cross-section of the side plates is S-shaped, so that both sides of the bucket present a streamlined structure.

[0007] Furthermore, the spacing between the two side plates at the front end of the bucket bottom plate is smaller than the spacing between the two side plates at the rear end of the bucket bottom plate.

[0008] Furthermore, the side plate comprises an upper side plate and a lower side plate, the cross-sections of the upper side plate and the lower side plate are both S-shaped, and the upper side plate is located directly above the lower side plate.

[0009] Furthermore, the top of the lower side plate is connected to the upper side plate, and the bottom is connected to the bucket bottom plate.

[0010] Furthermore, the bucket bottom plate is U-shaped, and the bottom of the lower side plate is adapted to the bucket bottom plate.

[0011] Furthermore, a front edge plate is fixedly connected to the front end of the bucket bottom plate, and two sides of the front edge plate are respectively fixedly connected to two upper side plates. A plurality of bucket teeth are connected to the front edge plate, and the bucket teeth are detachably connected to the front edge plate.

[0012] Furthermore, a bucket bottom sticking plate is fixedly connected to the lower surface of the bucket bottom plate, and the bucket bottom sticking plate is arc-shaped, and its shape is adapted to the lower surface of the bucket bottom plate, so that the bucket bottom sticking plate fits the bucket bottom plate.

[0013] Furthermore, a side plate is provided at the position where the outer side of the lower side plate contacts the bucket bottom plate, and the side plate is adapted to the shape of the outer surface of the lower side plate so that the side plate fits the lower side plate.

[0014] Furthermore, one end of the upper side plate close to the front blade plate is fixedly connected with a side tooth plate, the side tooth plate is located on the outer side of the upper side plate, and side teeth are arranged on the top of the side tooth plate.

[0023] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0024] A typical implementation of the present invention is as follows: Figure 1As shown, an excavator bucket structure includes a side plate 1 and a bucket bottom plate 2. The side plates 1 are provided with two, and the two side plates 1 are symmetrically arranged on both sides of the bucket bottom plate 2 and are perpendicular to the bucket bottom plate 2. The cross-section of the two side plates 1 is S-shaped, so that the two sides of the bucket have a streamlined structure.

[0025] Since the cross-section of the two side plates 1 is S-shaped, the spacing between the two side plates 1 is not unique. The spacing between the two side plates 1 at the front end of the bucket bottom plate 2 is smaller than the spacing between the two side plates 1 at the rear end of the bucket bottom plate 2. The bucket as a whole presents a structure that is narrow in front and wide in the back. This structure is beneficial for reducing the friction between the material and the bucket side plates when the bucket is inserted into the material or rotates in the material, thereby reducing the resistance during excavation.

[0026] like Figure 2 As shown, the side plate 1 includes an upper side plate 3 and a lower side plate 4, and the cross-sections of the upper side plate 3 and the lower side plate 4 are both S-shaped. The upper side plate 3 is located directly above the lower side plate 4, and the top of the lower side plate 4 is connected to the upper side plate 3, and the bottom is connected to the bucket bottom plate 2. The bucket bottom plate 2 is U-shaped, and the bottom of the lower side plate 4 is adapted to the bucket bottom plate 2, so as to achieve welding and fixation of the lower side plate 4 and the bucket bottom plate 2.

[0027] like Figure 3 As shown, the front end of the bucket bottom plate 2 is fixedly connected to a front edge plate 5, and the two sides of the front edge plate 5 are respectively fixedly connected to the two upper side plates 3. A plurality of bucket teeth 6 are connected to the front edge plate 5, and the bucket teeth 6 are detachably connected to the front edge plate 5. The bucket teeth 6 are used for excavation work, and can be removed from the front edge plate 5 for replacement after the bucket teeth 6 are worn.

[0028] The lower surface of the bucket bottom plate 2 is fixedly connected with a bucket bottom plate 7, and the bucket bottom plate 7 is arc-shaped, and its shape is adapted to the lower surface of the bucket bottom plate 2, so that the bucket bottom plate 7 is fitted with the bucket bottom plate 2, and the bucket bottom plate 2 is protected by the bucket bottom plate 7 to reduce the wear of the bucket bottom plate 2.

[0029] A side plate 8 is provided at the position where the outer side of the lower side plate 4 contacts the bucket bottom plate 2. The side plate 8 is adapted to the shape of the outer surface of the lower side plate 4, so that the side plate 8 is fitted with the lower side plate 4, and the side plate 8 is used to protect the lower side plate 4 to reduce the wear of the lower side plate 4.

[0030] The upper side plate 3 is fixedly connected to one end close to the front blade plate 5 with a side tooth plate 9, and the side tooth plate 9 is located outside the upper side plate 3. The top of the side tooth plate 9 is provided with side teeth 10, which cooperate with the bucket teeth 6 to improve the digging ability of the bucket.

[0031] The rear end of the bucket bottom plate 2 is fixedly connected with an ear plate 11, and the top and bottom ends of the ear plate 11 are both provided with shaft holes 12, which are connected to the bucket arm of the excavator through a rotating shaft, and the bucket is driven to move by the bucket arm.

[0032] The bucket of the utility model arranges both side plates into an S shape so that the bucket as a whole presents a streamlined structure that is narrow in the front and wide in the back. When the bucket is inserted into materials or rotates in materials, the streamlined side plates can reduce the friction between the materials and the bucket side plates, thereby reducing the wear on the bucket side plates and reducing the resistance during excavation.

[0033] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
