Description

Technical Field

[0001] This utility model relates to the technical field of coal mine roadway repair equipment, and in particular to a pusher mechanism for a coal mine roadway repair machine. Background Technology

[0002] In coal mine roadway repair operations, the bucket mechanism is an important component of the coal mine roadway repair machine, and the performance of its bucket structure directly affects the efficiency and quality of the repair work.

[0003] Currently, in traditional bucket structures, only one digging tooth can be installed in each assembly slot, and the digging teeth are installed sequentially in the assembly slots by bolts. However, this installation method has many problems. On the one hand, since only one digging tooth can be installed in each assembly slot, the number of digging teeth is limited. Under complex working conditions such as digging hard ore and rock, the digging capacity and wear resistance of the bucket are insufficient, which affects the smooth progress of roadway repair work. On the other hand, the installation process requires tightening the bolts one by one, which is cumbersome and has low installation efficiency.

[0004] Therefore, we provide a pusher mechanism for a coal mine roadway repair machine. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned technical problems by providing a pusher mechanism for a coal mine roadway repair machine, thus solving the problems of inconvenient installation and disassembly of existing bucket structures, limited number of digging teeth, and insufficient digging performance.

[0006] In view of this, the present invention provides a pusher mechanism for a coal mine roadway repair machine, including a pusher body, a digging tooth structure, and a locking structure;

[0007] The digging tooth structure is sequentially installed in the assembly groove at the inner bucket end edge of the push bucket body;

[0008] The digging tooth structure consists of two sets of digging tooth bodies and positioning blocks. The two sets of digging tooth bodies are respectively engaged in the rectangular slots provided by the positioning blocks by extension blocks integrally formed at the ends.

[0009] The locking structure includes a limiting rod, which limits the two sets of digging teeth bodies to the rectangular slots of the positioning block, and at the same time limits the entire digging tooth structure to the assembly slot of the bucket body.

[0010] Preferably, the two side walls of the positioning block are provided with limiting holes that are adapted to the limiting rod, and the limiting rod passes through the limiting holes to securely limit the digging tooth body in the rectangular slot of the positioning block.

[0011] Preferably, the working end of the digging tooth body is provided with small digging teeth, and the two sets of digging tooth bodies are engaged and assembled in the rectangular slot of the positioning block by the extension block, so that the digging tooth structure installed in a single assembly slot forms a digging unit composed of four digging teeth.

[0012] Preferably, the extension blocks at the upper ends of the two sets of digging teeth are tightly fitted into the rectangular slots of the positioning block in an integral molding structure, forming a spliced ​​filling and engaging structure, while the positioning block is fitted into the assembly slot of the bucket body.

[0013] Preferably, one end of the limiting rod is provided with a threaded structure, which is installed on the inner bucket side wall on the other side of the push bucket body in a spiral connection manner, and is locked and fixed by the fastening nut.

[0014] Preferably, protective plates are installed on both sides of the push bucket body, and the protective plates are fixed to the outer side walls at both ends of the push bucket body in a protective covering manner.

[0015] Preferably, each of the two side walls of the pusher body has a set of protective plates with an L-shaped structure, and the L-shaped structure is provided with a hollow protective partition, which respectively wraps and hides the two ends of the limiting rod.

[0016] Compared with the prior art, this utility model provides a pusher mechanism for a coal mine roadway repair machine, which has the following beneficial effects:

[0017] 1. Compared with traditional buckets where only one digging tooth can be installed in a single assembly slot, this utility model uses two sets of digging tooth bodies to engage and assemble in the rectangular slot of the positioning block, so that a digging unit containing four digging teeth is formed in a single assembly slot, which significantly increases the number of digging teeth. When dealing with complex working conditions such as hard rocks, more digging teeth work together, which effectively improves the digging capacity and wear resistance of the bucket mechanism and ensures the efficient progress of roadway repair work.

[0018] 2. Compared with the cumbersome method of installing digging teeth one by one with traditional bolts, this utility model adopts a structure in which the extension block of the digging tooth body and the positioning block are engaged with the slot, and the limiting rod is used for quick positioning and fixing. During installation, there is no need to tighten the bolts one by one. You only need to engage the digging tooth structure and insert the limiting rod to complete the installation. This greatly simplifies the installation process, significantly improves the installation efficiency, and reduces labor and time costs.

[0019] 3. In this utility model, the protective plates installed on both sides of the bucket body can protect both sides of the bucket body. Each side is provided with a set of protective plates with an L-shaped structure. The L-shaped structure has a hollow protective layer, which can effectively wrap and hide the two ends of the limiting rod, so as to prevent the limiting rod from being hit during the operation of the bucket body and affecting the stability of the bucket.

[0020] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0026] 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.

[0027] Example:

[0028] Please see Figure 1 - Figure 4 The pusher mechanism of a coal mine roadway repair machine in this embodiment includes: a pusher body 1, a digging tooth structure 2, and a locking structure; the digging tooth structure 2 is installed in the assembly groove 3 at the inner bucket end edge of the pusher body 1; the digging tooth structure 2 is composed of two sets of digging tooth bodies 21 and positioning blocks 24, and the two sets of digging tooth bodies 21 are respectively engaged in the rectangular slots 241 provided by the positioning blocks 24 through the extension blocks 23 integrally formed at the ends; the locking structure includes a limiting rod 4, which limits the two sets of digging tooth bodies 21 in the rectangular slots 241 of the positioning blocks 24, and at the same time limits the digging tooth structure 2 as a whole in the assembly groove 3 of the pusher body 1.

[0029] The design of this pusher mechanism, which uses the extension block 23 of the digging tooth body 21 to engage with the positioning block 24 and then fix it with the limiting rod 4, eliminates the need for cumbersome bolt tightening, greatly simplifies the installation and disassembly process of the digging tooth structure 2, significantly improves installation efficiency, and reduces maintenance difficulty and time costs.

[0030] In contrast, traditional buckets can only install one digging tooth in a single assembly slot 3, while this pusher mechanism doubles the number of digging teeth by combining two sets of digging tooth bodies 21 with positioning blocks 24 in a single assembly slot 3. This effectively enhances the breaking and grabbing capabilities of the pusher mechanism during excavation operations, making it more suitable for repair work under complex geological conditions in coal mine roadways.

[0031] The positioning block 24 has limiting holes on both sides that are adapted to the limiting rod 4. The limiting rod 4 passes through the limiting holes and is used to firmly limit the digging tooth body 21 in the rectangular slot 241 of the positioning block 24.

[0032] Among them, the working end of the digging tooth body 21 is provided with a small digging tooth 22. The two sets of digging tooth bodies 21 are engaged and assembled in the rectangular slot 241 of the positioning block 24 by the extension block 23, so that the digging tooth structure 2 installed in a single assembly slot 3 forms a digging unit composed of four digging teeth.

[0033] Among them, the extension blocks 23 at the upper end of the two sets of digging teeth body 21 are tightly fitted into the rectangular slots 241 of the positioning block 24 in an integral molding structure, forming a splicing filling and engaging structure. The positioning block 24 is fitted into the assembly slot 3 of the bucket body 1. The integrally molded extension blocks 23 and the positioning block 24 slots are tightly fitted together to form a stable splicing filling structure, which effectively avoids the loosening or displacement of the digging teeth due to uneven force during the digging process.

[0034] One end of the limiting rod 4 is provided with a threaded structure 41, which is installed on the inner bucket side wall on the other side of the push bucket body 1 in a spiral connection manner, and is locked and fixed by a fastening nut 42.

[0035] Among them, protective plates 5 are installed on both sides of the push bucket body 1, and the protective plates 5 are fixed to the outer side walls at both ends of the push bucket body 1 in a protective covering manner.

[0036] Among them, there is a set of protective plates 5 with an L-shaped structure in both sides of the push bucket body 1, and a hollow protective partition 51 is provided in the L-shaped structure. The hollow protective partition 51 respectively wraps and hides the two ends of the limiting rod 4 inside.

[0037] The protective plates 5 installed on both sides of the bucket body 1 can protect both sides of the bucket body 1. Each side is provided with a set of protective plates 5 with an L-shaped structure. The L-shaped structure has a hollow protective layer 51, which can effectively wrap and hide the two ends of the limit rod 4, so as to prevent the limit rod 4 from being hit during the operation of the bucket body 1 and affecting the stability of the bucket.

[0038] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
