Description

Technical Field

[0001] The utility model relates to the technical field of excavator bucket teeth, in particular to a detachable excavator bucket tooth. Background Art

[0002] An excavator is an important engineering machine with a wide range of applications. To facilitate excavation, the bucket of a traditional excavator is provided with protruding excavating teeth (bucket teeth for short). The bucket teeth are connected to the bucket tooth seat by pins. In normal use, the bucket teeth will wear out quickly, affecting the smooth progress of excavation. However, the worn bucket teeth cannot be repaired and can only be replaced, which is very costly.

[0003] At present, all bucket teeth on the market are integral, and the damage is mainly at the tip. When the tip is scrapped, you can consider reinstalling a tip for continued use, which can reduce more than half of the cost. Moreover, if forging is used to produce bucket teeth, due to the particularity of its shape, ordinary methods cannot be forged into shape in one time. Not only is the process complicated, but the cost is high and the appearance is poor. If it is divided into two parts for forging, the process requirements are very low, the cost is greatly reduced, and the internal quality and appearance quality can be guaranteed. However, the current split bucket teeth have low structural strength at the split connection, which is easy to be damaged and detached during normal use, resulting in a short service life. At the same time, it is inconvenient to disassemble and assemble, and the replacement efficiency is low.

[0004] Therefore, the existing demand is not met, and we propose a detachable excavator bucket tooth. Utility Model Content

DETAILED DESCRIPTION

[0022] 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.

[0023] Embodiment 1

[0024] See also Figure 1-Figure 4A detachable excavator bucket tooth includes a bucket tooth body 1, which is composed of a front bucket tooth 101, a rear tooth seat 102 and a connecting pin 103. The front bucket tooth 101 is sleeved on the rear tooth seat 102, and the connecting pin 103 is used to fix the front bucket tooth 101 and the rear tooth seat 102 accordingly.

[0025] A first accommodating cavity 106 is provided inside the front bucket tooth 101 , and a connecting plug 107 is integrally provided on the rear tooth seat 102 , and the rear tooth seat 102 is plugged into the first accommodating cavity 106 via the connecting plug 107 .

[0026] First connecting through slots 104 are formed on the inner walls of both sides of the first accommodating cavity 106 , and two first fixing holes 105 are formed around each of the first connecting through slots 104 .

[0027] Two second accommodating cavities 109 are defined inside the connecting plug block 107, and second connecting grooves 115 are defined on the inner walls on both sides of the connecting plug block 107. Each second connecting groove 115 is connected to the corresponding second accommodating cavity 109, and two second fixing holes 108 are also defined around the second connecting groove 115.

[0028] A connecting spring 116 is disposed inside each second accommodating cavity 109 , and one end of the connecting spring 116 is fixedly connected to the inner wall at the bottom of the second accommodating cavity 109 .

[0029] A clamping portion 110 is also integrally provided at one end of the connecting block 107 away from the front bucket tooth 101 , and the clamping portion 110 is used to clamp the rear end tooth seat 102 and the front bucket tooth 101 fixedly connected to the rear end tooth seat 102 on the excavator bucket.

[0030] Two fixing blocks 112 are fixedly provided on the plug rod of the connecting pin 103 , and each fixing block 112 is provided with a first threaded hole 111 , and two second threaded holes 113 are provided on the top cover of the connecting pin 103 at positions corresponding to the first threaded holes 111 .

[0031] Two fixing bolts 114 are also provided on the connecting pin 103 , and each fixing bolt 114 is used to fix the connecting pin 103 inside the corresponding first accommodating cavity 106 .

[0032] In this embodiment, since the first accommodating cavity 106 is provided inside the front bucket tooth 101, and the rear tooth holder 102 is provided with a connecting plug 107 corresponding to the shape of the first accommodating cavity 106, when the user assembles the front bucket tooth 101 and the rear tooth holder 102, it is only necessary to plug the connecting plug 107 provided on the rear tooth holder 102 into the first accommodating cavity 106;

[0033] Since first connecting grooves 104 are provided on the inner walls of both sides of the first accommodating cavity 106, and two second connecting grooves 115 are provided at positions of the connecting plug block 107 corresponding to the two first connecting grooves 104, and the two second connecting grooves 115 are also connected to the two second accommodating cavities 109 provided inside the connecting plug block 107;

[0034] Through the above arrangement, the user can achieve the fixing effect between the front bucket tooth 101 and the rear tooth seat 102 by sequentially passing the corresponding connecting pin 103 through the first connecting slot 104 and the second connecting slot 115;

[0035] Since two fixing blocks 112 are fixedly arranged at both ends of the connecting plug 103, when the connecting plug 103 is inserted into the first connecting slot 104 and the second connecting slot 115 in sequence, the user can rotate the connecting plug 103 accordingly. When the connecting plug 103 is rotated, the second threaded hole 113 located at the top cover of the connecting plug 103 and the corresponding fixing block 112 can be correspondingly overlapped with the first fixing hole 105 provided around the first connecting slot 104 and the second fixing hole 108 provided around the second connecting slot 115.

[0036] When the second threaded hole 113 and the corresponding fixing block 112 are completely overlapped with the first fixing hole 105 opened around the first connecting through groove 104 and the second fixing hole 108 opened around the second connecting through groove 115, the user can pass the corresponding fixing bolt 114 through the second threaded hole 113, the first fixing hole 105, the second fixing hole 108 and the first threaded hole 111 in sequence, so as to complete the fixing of the connecting pin 103 on the front bucket tooth 101 and the rear tooth seat 102. When the connecting pin 103 is fixed, the front bucket tooth 101 and the rear tooth seat 102 also complete the corresponding assembly effect;

[0037] It should be noted that, since a connecting spring 116 is fixedly arranged inside each second accommodating cavity 109, when the rod of the connecting pin 103 is inserted into the second accommodating cavity 109, the connecting spring 116 will be squeezed accordingly, and since the connecting pin 103 rotates, the fixing block 112 arranged on the rod of the first connecting slot 104 will be misaligned with the first connecting slot 104 and the second connecting slot 115 accordingly. Through this arrangement, on the one hand, the connection and fixing effect between the connecting pin 103 and the front bucket tooth 101 and the rear tooth seat 102 can be strengthened to a certain extent, so as to avoid the possibility that the connecting pin 103 may be accidentally loosened in the prior art, thereby causing the rear tooth seat 102 and the front bucket tooth 101 to separate;

[0038] On the other hand, since the force is mutual, when the rod of the connecting pin 103 squeezes the connecting spring 116, the connecting spring 116 will also squeeze the rod of the connecting pin 103 in the opposite direction. This arrangement allows the flipped fixing block 112 to abut against the inner wall of the second accommodating chamber 109 under the squeezing action of the connecting spring 116, thereby strengthening the connection effect between the connecting pin 103 and the second accommodating chamber 109, thereby improving the assembly tightness between the front bucket tooth 101 and the rear tooth seat 102 to a certain extent.

[0039] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
