Description

Technical Field

[0001] This utility model relates to the technical field of track teeth, and more specifically, to an embedded anti-digging tooth. Background Technology

[0002] In scenarios such as mining, tunnel engineering, military defense, or protection of important facilities, traditional protective structures (such as ordinary concrete and metal railings) are prone to structural damage and penetration when faced with excavation tools such as excavators and picks, and cannot effectively resist malicious excavation or engineering damage.

[0003] Traditional materials are prone to cracking and deformation under long-term stress or repeated excavation and impact, and their protective performance deteriorates over time, resulting in high maintenance costs. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an embedded anti-dig iron tooth with high strength and durability.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an embedded anti-digger tooth, comprising two parallel and equal-length elongated substrates, a connecting beam between the two substrates, and trapezoidal prism-structured teeth at the connection ends of the two substrates and the connecting beam. The bottom surface of the substrate is provided with a reinforcing layer, which consists of several horizontally arranged metal wires and longitudinally arranged pressure bars. The pressure bars restrict the metal wires to the bottom of the substrate to prevent them from falling off.

[0006] The present invention is further configured such that: a first reinforcing rib and a second reinforcing rib are provided on both sides of the iron tooth, and the thickness of the first and second reinforcing ribs is 1 / 4 to 1 / 2 of the thickness of the anti-digger iron tooth.

[0007] The present invention is further configured such that the tooth pitch of the anti-digging iron teeth is 1 / 3 to 1 / 2 of the length of the substrate.

[0008] The present invention is further configured such that: the base plate is symmetrically provided with limiting wing plates, and the portions of the limiting wing plates extending out of the base plate at both ends form protrusions, and the protrusions are arranged opposite to each other so that when two adjacent tracks are spliced ​​together, a limiting effect is formed.

[0009] The present invention is further configured such that: the bottom ends of the two substrates (1) are symmetrically provided with mounting blocks (10) for mounting pressure rods (5).

[0010] The beneficial effects of this utility model are:

[0011] 1. Two parallel and equal-length elongated base plates are connected by a connecting beam, forming a robust frame structure that ensures the iron teeth maintain a stable shape during operation, preventing deformation or wobbling. When excavating harder soil or encountering significant resistance, the base plates and connecting beams work together to withstand external forces, ensuring the overall stability of the iron teeth and thus improving work efficiency. The iron teeth, with their trapezoidal prism structure, are installed at the connection end between the base plates and the connecting beam. This trapezoidal prism structure has good mechanical properties, increasing the contact area and connection strength between the iron teeth and the base plates and connecting beams. During excavation, the iron teeth are firmly fixed to the base plates, preventing them from falling off and ensuring normal use, reducing work interruptions and equipment damage caused by tooth detachment. The reinforcing layer on the bottom surface of the base plates consists of transverse metal wires and longitudinal pressure bars. The pressure bars confine the metal wires to the bottom of the base plates. The metal wires have good toughness and tensile strength, dispersing the pressure and tension on the base plates and enhancing their overall strength. The longitudinal pressure bars further fix the metal wires, preventing them from falling off and ensuring the effectiveness of the reinforcing layer.

[0012] 2. When the anti-digging teeth encounter hard objects during excavation, they experience significant impact forces. The first and second reinforcing ribs disperse these impact forces over a wider area of ​​the teeth, preventing localized stress concentration. For example, when excavating soil containing rocks, the reinforcing ribs can distribute the impact force of the rocks on the tip of the teeth to the sides and roots, reducing the risk of cracks or even breakage and significantly improving the durability of the teeth. The thickness of the first and second reinforcing ribs, within a suitable range of 1 / 4 to 1 / 2 of the anti-digging teeth's thickness, enhances the overall rigidity of the teeth. During long-term excavation operations, the teeth may deform due to repeated stress, and the reinforcing ribs effectively resist this deformation. The tooth pitch of the anti-digging teeth is between 1 / 3 and 1 / 2 of the base plate length. A suitable tooth pitch improves excavation efficiency while reducing unnecessary energy consumption. If the tooth pitch is too large, multiple excavations may be required to achieve the desired effect; if the tooth pitch is too small, although the excavation is more precise, it increases excavation resistance and time.

[0013] 3. The design of the limiting flanges and protrusions reduces the probability of track malfunctions during operation, minimizing safety accidents caused by track loosening or detachment. When splicing adjacent tracks, the opposing protrusions act like precise navigation markers. They clearly indicate the splicing position and direction, allowing operators to quickly and accurately complete the splicing simply by aligning the protrusions on the two tracks, significantly reducing alignment adjustment time and improving splicing efficiency. The limiting effect of the protrusions ensures a high degree of consistency between adjacent tracks after splicing, making the tracks run more smoothly and preventing problems such as track deviation and jamming caused by uneven splicing, thus improving the overall operational stability of the tracked equipment.

[0014] 4. The mounting block provides a clear and precise position for the pressure bar installation. During installation, workers can quickly and accurately install the pressure bar in place based on the position of the mounting block, avoiding deviations in the pressure bar installation position and ensuring the stability and standardization of the reinforcement layer structure. The pressure bar is higher than the bottom of the substrate, allowing for better contact with the embedded body and forming a firm connection when embedded. Attached Figure Description

[0018] Reference Figures 1 to 2 The embodiments of this utility model will be further described below.

[0019] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” are used in the embodiments to describe the relationship of one element or feature shown in the figures relative to another element or feature. It should be understood that, in addition to the orientations shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figures is inverted, an element described as being “down” of other elements or features would be positioned “up” of those other elements or features. Therefore, the exemplary term “down” can encompass both up and down orientations. The device may be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0020] Moreover, relational terms such as “first” and “second” are used merely to distinguish one component from another that has the same name, without necessarily requiring or implying any such actual relationship or order between the components.

[0021] Figures 1 to 2An embedded anti-digging tooth is shown, comprising two parallel and equal-length elongated base plates 1, with a connecting beam 2 between the two base plates 1. The key feature is that each of the connection ends between the base plates 1 and the connecting beam 2 is equipped with a trapezoidal prism-structured tooth 3. The two parallel and equal-length elongated base plates 1 are connected by the connecting beam 2, forming a robust frame structure that allows the tooth 3 to maintain a stable shape during operation, preventing deformation or shaking. When digging in hard soil or encountering significant resistance, the base plates 1 and the connecting beam 2 cooperate to jointly bear external forces, ensuring the overall stability of the tooth 3 and thus improving work efficiency. The trapezoidal prism structure of the tooth 3 at the connection end between the base plates 1 and the connecting beam 2 provides good mechanical properties, increasing the contact area and connection strength between the tooth 3 and the base plates 1 and the connecting beam 2. During digging, the tooth 3 is firmly fixed to the base plates 1, preventing it from falling off, ensuring normal use of the tooth 3, and reducing work interruptions and equipment damage caused by tooth 3 detachment. The bottom surface of the substrate 1 is provided with a reinforcing layer, which consists of several horizontally arranged metal wires 4 and longitudinally arranged pressure bars 5. The pressure bars 5 restrict the metal wires 4 to the bottom of the substrate 1. The metal wires 4 have good toughness and tensile strength, which can disperse the pressure and tension on the substrate 1 and enhance the overall strength of the substrate 1. The longitudinal pressure bars 5 further fix the metal wires 4 to prevent them from falling off, thus ensuring the effectiveness of the reinforcing layer.

[0022] The metal wire is placed at a designated position at the bottom of the embedded anti-digger teeth and then put into the mold for manufacturing the track together with the glue, and vulcanized.

[0023] The iron tooth 3 is provided with a first reinforcing rib 6 and a second reinforcing rib 7 on both sides. When the iron tooth 3 encounters a hard object during excavation, it will be subjected to a large impact force. The first and second reinforcing ribs can disperse these impact forces over a larger area of ​​the iron tooth 3, avoiding local stress concentration. For example, when excavating soil containing stones, the reinforcing ribs can disperse the impact force of the stones on the tip of the iron tooth 3 to the side and root of the iron tooth 3, reducing the risk of cracks or even breakage of the iron tooth 3, and greatly improving the durability of the iron tooth 3.

[0024] When the thickness of the first and second reinforcing ribs is less than 1 / 4 of the thickness of the anti-dismantling tooth 3, the reinforcing ribs are not strong enough and are prone to deformation and breakage under stress, failing to effectively strengthen the structure. This weakens the overall rigidity of the anti-dismantling tooth 3 and may affect its performance and service life. When the thickness of the first and second reinforcing ribs is greater than 1 / 2 of the thickness of the anti-dismantling tooth 3, it increases material costs and weight, potentially making the structure too bulky. It may also affect the flexibility and installation adaptability of the anti-dismantling tooth 3, and may even cause stress concentration due to excessive thickness, leading to other structural problems. Therefore, the optimal thickness of the first and second reinforcing ribs is between 1 / 4 and 1 / 2 of the thickness of the anti-dismantling tooth 3. Within this appropriate range, the overall rigidity of the tooth 3 can be enhanced. During long-term excavation operations, the tooth 3 may deform due to repeated stress, and the reinforcing ribs can effectively resist this deformation.

[0025] When the tooth pitch of the anti-digger teeth 3 is less than 1 / 3 of the length of the base plate 1, the teeth 3 are too dense, which will increase the material consumption and processing cost. The excessively dense tooth gaps may cause debris to accumulate, affecting the normal use of the teeth 3. It may also cause installation difficulties due to the overly compact structure, and even cause deformation due to too many stress points on the base plate 1. When the tooth pitch of the anti-digger teeth 3 is greater than 1 / 2 of the length of the base plate 1, the teeth 3 are sparsely distributed, the number of teeth per unit area is reduced, the blocking and biting ability during digging is reduced, and it is easy to be pried open or dug by external force, which greatly reduces the protective effect. At the same time, it may also cause uneven stress on the teeth 3, local stress concentration, and increase the risk of breakage. Therefore, the optimal tooth pitch of the anti-digger teeth 3 is between 1 / 3 and 1 / 2 of the length of the base plate 1. The moderate distribution density of the teeth 3 can ensure sufficient anti-digger blocking force, and avoid problems such as material waste and stress concentration caused by excessive density or sparseness. At the same time, this range can be adapted to the structural strength of the base plate 1, reduce interference during installation, and ensure the stability of the overall protective device.

[0026] Two base plates 1 are symmetrically provided with limiting wing plates 8. The portions of the limiting wing plates 8 extending beyond the base plates 1 form protrusions 9. These protrusions 9 are positioned opposite each other. The design of the limiting wing plates 8 and the protrusions 9 reduces the probability of track malfunctions during operation, minimizing safety accidents caused by track loosening or detachment. When two adjacent tracks are spliced, the opposing protrusions 9 act as precise navigation markers. They clearly indicate the splicing position and direction. Operators only need to align the protrusions 9 on the two tracks to quickly and accurately complete the splicing, greatly reducing alignment adjustment time and improving splicing efficiency. The limiting function of the protrusions 9 ensures that adjacent tracks maintain a high degree of consistency after splicing, making the tracks run more smoothly and avoiding problems such as track deviation and jamming caused by uneven splicing, thus improving the overall operational stability of the tracked equipment.

[0027] Two mounting blocks 10 are symmetrically provided at both ends of the bottom of the two substrates 1 for mounting the pressure rods 5, so that they are higher than the bottom of the substrates 1. The mounting blocks 10 provide a clear and precise position for the installation of the pressure rods 5. During the installation process, the workers can quickly and accurately install the pressure rods 5 into place according to the position of the mounting blocks 10, avoiding deviations in the installation position of the pressure rods 5 and ensuring the stability and standardization of the reinforcing layer structure.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model should be included within the protection scope of the present utility model.
