Description

Technical Field

[0001] This utility model relates to the field of excavator technology, specifically to an excavator bucket tooth with adjustable spacing. Background Technology

[0002] An excavator, also known as a digging machine or excavator, is an earthmoving machine that uses a bucket to excavate materials above or below the machine's bearing surface and load them into transport vehicles or unload them at a stockpile. The materials excavated by excavators are mainly soil, coal, silt, and pre-loosened soil and rock. In recent years, the development of construction machinery has been relatively rapid, and excavators have become one of the most important types of construction machinery. The three most important parameters of an excavator are: operating weight (mass), engine power, and bucket capacity. The excavator bucket teeth are a crucial component of the excavator bucket, similar to human teeth, and are also wear parts. They are a combination of tooth bases and tooth tips connected by a pin. Different working environments and excavated objects require different tooth spacings. However, since the bucket teeth are fixedly installed on the bucket, the tooth spacing is also fixed, and the only way to meet the needs is to change buckets with different tooth spacings. Changing buckets is very inconvenient. Therefore, we propose an excavator bucket tooth with adjustable tooth spacing. Utility Model Content

[0003] The purpose of this invention is to provide an excavator bucket tooth with adjustable spacing to solve the problem of fixed spacing of excavator bucket teeth mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an excavator bucket tooth with adjustable spacing, comprising a bucket, a sliding groove at the end of the bucket, seven tooth seats slidably installed in the sliding groove, the tooth seats being connected by spring plates, a rotating sleeve fixedly installed at the middle tooth seat of the sliding groove, gaps on both sides of the rotating sleeve, through which the spring plates can pass, fixed shafts installed on both sides of the sliding groove, spring plates also installed on the fixed shafts and connected to the tooth seats, a protective sleeve installed outside the sliding groove, tooth tips connected to the tooth seats, pins inserted between the tooth tips and the tooth seats, and a mud-blocking mechanism also provided on the protective sleeve.

[0005] The sliding groove is long and narrow, and its cross-section is a horizontal "T" shape.

[0006] The gear seat has a rotating shaft fixedly installed below it. The rotating shaft is locked in a sliding groove and has a spring plate on it. The gear seat has two through first insertion holes on its side. The angle formed by the first insertion holes is 90 degrees. The pin can be inserted into the first insertion holes. The gear seat has two long slots of the same size and perpendicular to each other. The long slots are aligned with the first insertion holes. The gear seat also has a round hole in the middle.

[0007] The protective sleeve is divided into two parts. The protective sleeve is installed on the upper and lower sides of the sliding groove and is fixedly connected to the bucket. The tooth seat can be inserted between the protective sleeves.

[0008] Among them, a concave block is fixedly connected below the tooth tip. The concave block can be inserted into the long groove and fixedly inserted into the sliding groove. A cylindrical block is fixedly connected inside the concave block. A second through hole is opened on the side of the cylindrical block.

[0009] The cylindrical block has the same diameter as the circular hole and can be inserted into the circular hole. The second insertion hole has the same diameter as the first insertion hole, and the second insertion hole is aligned with the first insertion hole when the cylindrical block is inserted into the circular hole.

[0010] The mud-blocking mechanism includes a sliding shaft, which is fixedly installed above the sliding groove and inside the protective sleeve. A mudguard is slidably installed on the sliding shaft. The mudguard is installed between the tooth seats. A mudguard is also installed between the tooth seats and the bucket. The mudguard is made of stretchable and foldable metal material.

[0011] This utility model has at least the following beneficial effects:

[0012] After the sliding groove is opened at the end of the bucket, the toothed seats can slide freely. At the same time, a rotating sleeve is installed on the middle toothed seat to restrict its left and right sliding. The toothed seats are connected by spring plates. When the middle toothed seat is rotated to retract the spring plate, the distance between the toothed seats is also reduced. After rotating the toothed seat 90 degrees and then inserting the tooth tip, the toothed seat can no longer rotate or move due to the restriction of the tooth tip, thus fixing the toothed seat. At the same time, a mud-blocking mechanism is set between the toothed seats, which prevents soil from entering the sliding groove while the toothed seat moves without hindering its movement.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 11 Example 1

[0027] This utility model provides a technical solution: an excavator bucket tooth with adjustable spacing, including a bucket 1. A sliding groove 2 is formed at the end of the bucket 1. The sliding groove 2 is elongated and has a transverse "T"-shaped cross-section. A protective sleeve 7 is fitted over the sliding groove 2. The protective sleeve 7 is divided into two parts, which are respectively installed on the upper and lower sides of the sliding groove 2 and fixedly connected to the bucket 1. Seven tooth seats 3 are slidably installed inside the sliding groove 2. The tooth seats 3 are connected by spring plates 4. A rotating shaft 30 is fixedly installed below the tooth seats 3. The rotating shaft 30 is engaged within the sliding groove 2, preventing the tooth seats 3 from detaching from the sliding groove 2. The rotating shaft 30 is equipped with spring plates 4. Two through first insertion holes 31 are formed on the side of the tooth seats 3. The included angle is 90 degrees, and the pin 9 can be inserted into the first insertion hole 31. The gear seat 3 has two long slots 32 of the same size and perpendicular to each other. The long slots 32 are aligned with the first insertion hole 31. The gear seat 3 also has a round hole 33 in the middle. The sliding groove 2 has a rotating sleeve 5 fixedly installed at the middle gear seat 3. The rotating sleeve 5 has gaps 50 on both sides, and the spring plate 4 can pass through the gaps 50. The sliding groove 2 has fixed shafts 6 on both sides. The fixed shafts 6 also have spring plates 4 and are connected to the gear seat 3. When the middle gear seat 3 is rotated, the spring plate 4 also rolls up. At the same time, the other gear seats 3 rotate and drive the spring plates 4 to roll up. The gear seats 3 on both sides gradually move closer to the middle gear seat 3, and the distance between the gear seats 3 is reduced.

[0028] A tooth tip 8 is connected to the tooth base 3, and a pin 9 is inserted between the tooth tip 8 and the tooth base 3. A concave block 80 is fixedly connected below the tooth tip 8. The concave block 80 can be inserted into the long groove 32 and can also be fixed in the sliding groove 2. A cylindrical block 81 is fixedly connected inside the concave block 80. A second through hole 82 is opened on the side of the cylindrical block 81. The cylindrical block 81 has the same diameter as the round hole 33 and can be inserted into the round hole 33. The second through hole 82 has the same diameter as the first through hole 31. When the cylindrical block 81 is inserted into the round hole 33, the second through hole 82 is aligned with the first through hole 31. After rotating the tooth base 3 by 90 degrees, the tooth tip 8 is inserted. At this time, the tooth tip 8 is also inserted into the sliding groove 2. Then, the pin 9 is inserted between the tooth tip 8 and the tooth base 3. Due to the restriction of the tooth tip 8, the tooth base 3 can no longer rotate or move, thus fixing the tooth base 3.

[0029] The protective sleeve 7 is also equipped with a mud-blocking mechanism 10, which includes a sliding shaft 100. The sliding shaft 100 is fixedly installed above the sliding groove 2 and located inside the protective sleeve 7. A mud-blocking plate 101 is slidably installed on the sliding shaft 100. The mud-blocking plate 101 is installed between the tooth seats 3. A mud-blocking plate 101 is also installed between the tooth seats 3 and the bucket 1. The mud-blocking plate 101 is made of stretchable and foldable metal material, which can prevent mud from entering the sliding groove 2 when the excavator is working, and at the same time, it does not hinder the movement of the tooth seats 3 when it is necessary to adjust the spacing of the tooth seats 3.

[0030] Example 2

[0031] In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that rubber blocks 102 are added to both ends of the mudguard 101 to improve the sealing of the sliding groove 2 and prevent dust and moisture from entering the sliding groove 2.
