Description

Technical Field

[0001] The utility model relates to the technical field of shovel teeth, in particular to a shovel tooth for an excavator loader which is easy to disassemble and assemble. Background Art

[0002] The bottom edge of the excavator bucket or forklift bucket is provided with a tooth head. In order to prevent the tooth head from breaking and wearing quickly, it is necessary to set a shovel tooth on the tooth head. Due to the small spacing between the shovel teeth, the pin shaft locking the shovel teeth needs to be knocked to be pulled out. The existing shovel teeth are as follows Figure 5 As shown in the figure, the pin hole is horizontal, so when the pin shaft is pulled out or installed, the tooth head next to it will hinder the operation. In addition, the existing shovel teeth have no reinforcement structure, which makes them easy to break. Therefore, we propose a shovel tooth for an excavator loader that is easy to disassemble and assemble. Utility Model Content

[0003] In view of the disadvantage that the existing shovel tooth pin shaft is inconvenient to disassemble, the utility model provides an excavator loader shovel tooth that is easy to disassemble and assemble, has the advantages of allowing the pin shaft to be vertically connected to the shovel tooth and the shovel tooth has high strength, and solves the problems raised in the above background technology.

[0004] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0005] A shovel tooth for an excavator loader that is easy to disassemble and assemble is designed, comprising a tooth body, a receiving opening is arranged at one end of the tooth body, clamping plates are connected to both upper and lower ends of the receiving opening, and two reinforcing ribs are symmetrically arranged on one side of the two clamping plates that are away from each other;

[0006] A reinforcing seat with a strip structure is provided on the upper and lower surfaces of the tooth body, and the end of the reinforcing rib is connected to the end of the reinforcing seat to form a whole;

[0007] A certain distance is arranged between two reinforcing ribs on the same layer, and the distance forms a mounting groove, and a pin hole is arranged on the clamping plate in the mounting groove.

[0008] Preferably, the tooth body is in a strip shape, with an upper inclined surface at the top and a lower inclined surface at the bottom, the angle between the upper inclined surface and the horizontal plane is 15°-30°, and the angle between the lower inclined surface and the horizontal plane is 35°-75°.

[0009] Preferably, the side surfaces of the two reinforcement seats that are away from each other are both inclined surfaces.

[0010] Preferably, notches are provided on both sides of one end of the tooth body away from the clamping plate, so that the end of the tooth body becomes pointed.

[0011] Compared with the prior art, the utility model, when in use, 1. The reinforcing seat and the two reinforcing ribs form a "Y"-shaped supporting mechanism, which can effectively support the tooth body, prevent the shovel teeth from deformation and breakage, and increase the strength of the shovel teeth;

[0012] 2. The pin hole is set in the installation groove, which is perpendicular to the bottom of the bucket instead of parallel to the bottom of the bucket, so that it is convenient to insert and remove the pin shaft. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figures 1 to 4 The utility model provides a technical solution: a shovel tooth of an excavator loader that is easy to disassemble and assemble, comprising a tooth body 1, the tooth body 1 is a strip-shaped structure in the overall view, but the tooth body 1 is in the shape of a strip, such as Figure 3 As shown, an upper inclined surface 8 is provided at the top of the tooth body 1, and a lower inclined surface 9 is provided at the bottom thereof. The angle between the upper inclined surface 8 and the horizontal plane is A, 15°≤A≤30°, and the angle between the lower inclined surface 9 and the horizontal plane is B, 35°≤B≤75°, that is, the angle A is greater than the angle B, so that the tooth body 1 is triangular in the side view as a whole.

[0021] One end of the tooth body 1 is provided with a receiving opening 7, which is used to be clamped on the tooth head of the bucket. The size and shape of the receiving cavity match the tooth head. Clamps 6 are connected to the upper and lower ends of the receiving opening 7. When the tooth body 1 is clamped on the tooth head, the two clamps 6 are clamped on the upper and lower sides of the bucket edge. The spacing between the two clamps 6 is consistent with the thickness of the bucket edge. In this way, the bucket edge is clamped between the clamps 6, so that the contact area between the shovel tooth and the bucket is increased, which ensures the stability of the shovel tooth. After the shovel tooth is squeezed during excavation, the clamps 6 can support the shovel tooth.

[0022] like Figure 1 and Figure 2 As shown, two reinforcing ribs 3 are symmetrically arranged on one side of the two clamping plates 6 away from each other, and reinforcing seats 2 of strip-shaped structures are arranged on the upper and lower surfaces of the tooth body 1. The ends of the reinforcing ribs 3 are connected to the ends of the reinforcing seats 2 to form a whole, and the reinforcing seats 2 and the two reinforcing ribs 3 form a "Y"-shaped structure. When the shovel teeth are subjected to force, the reinforcing seats 2 and the reinforcing ribs 3 can both support the shovel teeth to prevent the shovel teeth from deformation and breakage, thereby increasing the strength of the shovel teeth.

[0023] like Figure 1 As shown, Figure 4 In the existing shovel tooth structure shown, the pin hole is opened on the side, and the pin hole is parallel to the bottom of the bucket. However, in this solution, a certain distance is set between two reinforcing ribs 3 on the same layer, and the distance forms a mounting groove 4. A pin hole 5 is set on the clamping plate 6 in the mounting groove 4, and a hole corresponding to the pin hole 5 is set on the bucket. When the edge of the bucket is placed between the clamping plates, the pin hole can be locked by a pin shaft. It should be noted that the pin hole 5 is perpendicular to the bottom of the bucket, not parallel to the bottom of the bucket;

[0024] The advantage of this design is that when the pin needs to be knocked to tighten, the vertical downward design of the pin hole 5 makes it easy to insert the pin. At the same time, it is convenient to use a knocking tool such as an iron rod to push it out during disassembly. Moreover, both ends of the pin are placed in the installation groove 4. Objects passing through the bucket during work will not directly contact the pin, making the pin installation more stable.

[0025] Furthermore, the surfaces of the two reinforcing seats 2 that are away from each other are both inclined surfaces 10, that is, the reinforcing seats 2 are both inclined toward the end of the tooth body 1, and notches 11 are provided on both sides of the end of the tooth body 1 away from the splint 6, so that the end of the tooth body 1 becomes pointed, allowing the bucket to shovel into the ground more easily.
