Description

Technical Field

[0001] This invention belongs to the field of bucket tooth technology, specifically relating to an excavator bucket with a tooth tip wear warning structure. Background Technology

[0002] As a core piece of equipment in the field of engineering construction, the performance of the bucket of an excavator directly determines the construction efficiency and cost control. The bucket teeth, as the key vulnerable parts that come into direct contact with materials on the bucket, play a core role in cutting and crushing materials. Their wear condition has a significant impact on the overall operating effect of the excavator. In actual engineering applications, the bucket teeth need to continuously withstand the impact, friction and compression of materials, and the wear rate of the tooth tip is extremely fast. Therefore, it is necessary to design an excavator bucket with a tooth tip wear warning structure.

[0003] The internal structure of existing bucket teeth is relatively simple, and most of them do not have a warning function. During operation, the teeth will directly collide with hard objects, which will increase the wear rate of the teeth and shorten their service life. In addition, when sensors for detecting the wear performance of existing bucket teeth are added inside, most of them do not have a buffer function. This will cause the sensors to vibrate greatly during operation, resulting in loosening or damage of parts and shortening the service life of the sensors. Summary of the Invention

[0004] The purpose of this invention is to provide an excavator bucket with a simple structure and reasonable design, featuring a tooth tip wear warning structure, in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions: An excavator bucket with a tooth tip wear warning structure includes a bucket assembly, the bucket assembly including multiple tooth seats and bucket teeth, each of the multiple bucket teeth having an opening groove on one side that fits outside the tooth seat, each of the multiple tooth seats having a detection component that mates with the bucket teeth on one side, each of the multiple opening grooves having a storage cavity extending into the inside of the bucket teeth, and each of the multiple storage cavities having a sealing drive component that mates with the detection component at the opening. The detection assembly includes a mounting cavity located on one side of the gear seat, a pressure sensor fixed in the middle of one side of the mounting cavity, and a wire that passes through the inside of the pressure sensor and is electrically connected to the driver's cab.

[0006] As a further optimization of the present invention, sleeves are fixed at both ends of one side of the mounting cavity, springs are fixed at one side of the inside of the two sleeves, and resistance blocks that are fixed to the other end of the springs slide on the other side of the inside of the two sleeves.

[0007] As a further optimization of the present invention, a bucket is fixed together on the side of the multiple tooth seats away from the bucket teeth, and the tooth seats and bucket teeth are fixed by a fixing pin at the fitting position. A sealing groove is provided inside the opening groove on the side near the storage cavity.

[0008] As a further optimization of the present invention, the sealing drive assembly includes a sealing cover plate placed inside the opening groove and covering the storage cavity, and a sealing plug extending into the storage cavity is fixed on the side of the sealing cover plate near the storage cavity.

[0009] As a further optimization of the present invention, a sealing ring is fixed at the edge of the sealing cover near the storage cavity, and the sealing cover extends into the interior of the sealing groove and fits against its interior.

[0010] As a further optimization of the present invention, a pressure block is fixedly installed at the middle position of the sealing cover on the side away from the storage cavity, and the pressure block extends into the interior of the mounting cavity and cooperates with the pressure sensor.

[0011] As a further optimization of the present invention, the sealing cover plate is fixedly installed with limit rods at both ends near the pressure block, and both limit rods slide into the inside of the sleeve and cooperate with the pressure block.

[0012] The beneficial effects of this invention are as follows: 1. This invention creates a storage cavity inside the bucket teeth. When the bucket teeth wear down, the leakage of liquid in the storage cavity can alert the operator, ensuring the intuitive performance of the wear warning. At the same time, the pressure sensor can alert the operator when the bucket teeth come into contact with hard objects, making it easier for the operator to adjust the working area in time, reducing the pre-wear function when the teeth are stuck, and extending the service life of the slot.

[0013] 2. This invention, through the structural design of a sleeve, spring, resisting block, and limiting rod, can achieve a buffering function for the pressure sensor under pressure from the resisting block, preventing damage or loosening of internal parts of the pressure sensor caused by direct resistance, thereby extending the service life of the pressure sensor. Finally, the sealing drive assembly adopts a double sealing structure of "sealing plug + sealing ring". The sealing plug extends deep into the storage cavity to form the first layer of protection, and the sealing ring is embedded in the sealing groove to form the second layer of protection, effectively preventing the outflow of liquid inside the storage cavity and ensuring the long-term stable operation of core components such as the pressure sensor and spring.

Detailed Implementation

[0016] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0017] Example 1: As Figure 1 , Figure 2 As shown, an excavator bucket with a tooth tip wear warning structure includes a bucket assembly 1, a detection assembly 2, and a sealing drive assembly 3. The components work together to realize the digging function and tooth tip wear warning function of the bucket. The bucket assembly 1 is the core load-bearing structure, the detection assembly 2 is responsible for providing warnings to the operator, and the sealing drive assembly 3 not only provides sealing protection but also provides triggering conditions for the detection assembly 2. The three components form a complete functional system through precise structural cooperation.

[0018] like Figure 1 , Figure 2As shown, the bucket assembly 1 includes a bucket 100, multiple tooth holders 101, and multiple bucket teeth 102. The tooth holders 101 are evenly spaced and fixed at the opening edge of the bucket 100. The tooth holders 101 and the bucket 100 are fixedly connected by welding to ensure connection strength to withstand the impact force during digging operations. Each tooth holder 101 is fitted with one bucket tooth 102. The bucket tooth 102, as a component directly in contact with the material, has an opening slot 106 on one side that matches the shape of the tooth holder 101. Initial assembly is achieved by fitting the tooth holder 101 with the opening slot 106. To ensure assembly stability, the tooth holders 101 and bucket teeth 102 are further... A coaxial pin hole is provided at the fitting position of 2. The two are fixed by a fixing pin 103 passing through the pin hole to prevent the bucket tooth 102 from loosening or falling off during operation. Inside the opening groove 106 of each bucket tooth 102, a storage cavity 104 extending into the inside of the bucket tooth 102 is provided. The storage cavity 104 is used to store the indicator liquid (the indicator liquid is a fluid liquid with a distinct color). Its opening faces the tooth seat 101. At the same time, an annular sealing groove 105 is provided inside the opening groove 106 near the opening of the storage cavity 104. The sealing groove 105 cooperates with the subsequent sealing drive assembly 3 to achieve a sealing and protection effect.

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, each tooth holder 101 is equipped with a detection assembly 2 on the side near the bucket tooth 102. The detection assembly 2 includes a mounting cavity 204, a pressure sensor 200, a sleeve 201, a spring 202, and a resisting block 203. The mounting cavity 204 is a groove structure formed on the end face of the tooth holder 101, and its position corresponds to the storage cavity 104 on the bucket tooth 102, ensuring that the sealing drive assembly 3 can extend into the mounting cavity 204 after assembly. The pressure sensor 200 is fixedly installed in the middle of one side of the mounting cavity 204, with its sensing end facing the opening of the mounting cavity 204. A wire is fixed inside the pressure sensor 200, and the wire passes through the interior of the tooth holder 101 and the bucket 100. A channel is provided, which is ultimately electrically connected to the warning device in the main cab of the excavator to realize the transmission of pressure signals and warning triggering. Two sleeves 201 are symmetrically fixed at both ends on one side inside the mounting cavity 204. The sleeve 201 is a hollow structure with one end closed, and its opening direction is consistent with the sensing end direction of the pressure sensor 200. A spring 202 is fixed inside each sleeve 201 near the closed end. The other end of the spring 202 is fixedly connected to a resisting block 203. The resisting block 203 is a cylindrical structure adapted to the inner wall of the sleeve 201 and can slide along the axial direction inside the sleeve 201. In its natural state, the spring 202 pushes the resisting block 203 out of the opening of the sleeve 201 by a certain length.

[0020] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the sealing drive assembly 3 is installed at the opening of the storage cavity 104 of each bucket tooth 102 to achieve sealing protection of the storage cavity 104 and to form a mechanical cooperation with the detection assembly 2. It includes a sealing cover plate 300, a pressing block 301, a limiting rod 302, and a sealing ring 303. The sealing cover plate 300 is a plate-shaped structure adapted to the opening of the storage cavity 104, placed inside the opening groove 106 and covering the opening of the storage cavity 104. A sealing plug extending into the storage cavity 104 is fixed to the side of the sealing cover plate 300 near the storage cavity 104. The sealing plug fits tightly against the inner wall of the storage cavity 104, forming a primary seal. An annular sealing ring 303 is fixed at the edge of the sealing cover plate 300 near the storage cavity 104. The sealing ring 303 is made of wear-resistant rubber. When the sealing cover plate 300 is installed in place, its edge extends into the sealing groove 105 of the bucket tooth 102 and fits tightly against the inner wall of the sealing groove 105, achieving a secondary seal. A cylindrical pressure block 301 is fixedly installed at the middle position of the sealing cover 300 on the side away from the storage cavity 104. The axis of the pressure block 301 coincides with the axis of the pressure sensor 200. After the bucket tooth 102 and the tooth seat 101 are assembled in place, the pressure block 301 extends into the mounting cavity 204 of the detection component 2, and its end face contacts the sensing end of the pressure sensor 200, forming an initial pressure trigger state. At both ends of the sealing cover 300 near the pressure block 301... Two limiting rods 302 are symmetrically fixedly installed. The positions of the limiting rods 302 correspond one-to-one with the two sleeves 201 in the mounting cavity 204. Their diameters are adapted to the inner diameter of the sleeves 201. After assembly, the limiting rods 302 slide and extend into the interior of the sleeves 201 and come into contact with the resisting block 203. At this time, the spring 202 is in a slightly compressed state. The resisting block 203 applies a reverse elastic force to the limiting rods 302 to ensure that the resisting block 301 and the pressure sensor 200 maintain stable contact.

[0021] It should be noted that in the initial assembly state of this excavator bucket with tooth tip wear warning structure, the bucket teeth 102 are fitted onto the tooth seat 101 through the opening slot 106 and locked by the fixing pin 103. At this time, the pressure block 301 of the sealing drive assembly 3 is in close contact with the pressure sensor 200 of the detection assembly 2. The pressure sensor 200 detects the initial pressure value and transmits it to the control module in the main cab. The control module sets the initial value as the reference value. As the excavator continues to operate, the tooth tips of the bucket teeth 102 continuously rub against the material and generate wear. When the wear reaches a certain level, the overall length of the bucket teeth 102 shortens, causing the outside of the bucket teeth 102 to form a gap with the inside of the storage cavity 104 due to wear. Then, the liquid with obvious color inside the storage cavity 104 will flow out through the gap, realizing the wear warning function for the operator.

[0022] Furthermore, when the bucket tooth 102 collides significantly with a hard object during operation, a certain pressure is applied to the bucket tooth 102, which then pushes the pressure block 301 to press against the pressure sensor 200. The pressure signal transmitted by the pressure sensor 200 helps the operator to provide a warning. When the operator is aware that a hard object has appeared at the location of the bucket tooth 102, the operator can promptly move the bucket tooth 102 to a different position, thus realizing a warning function for the bucket tooth 102 when it is about to wear out during operation.

[0023] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
