Technical Field
[0001] The utility model relates to the technical field of picks, in particular to a cermet pick. Background Technique
[0002] A cermet pick is an efficient wear-resistant tool used in mines and construction machinery. It usually forms a high-hardness and high-wear-resistant cermet layer on the working surface of the pick through a special manufacturing process. This composite material combines the toughness of metal and the hardness of ceramics, and can maintain its performance in a harsh working environment for a long time, reducing wear and maintenance costs.
[0003] As disclosed in a cermet pick in Chinese Patent CN115450621A, a threaded mounting rod is provided at one end of the pick body away from the positioning rod. A threaded hole connected to the threaded mounting rod is provided on the circular mounting plate. The pick body is threadedly connected to the threaded hole on the circular mounting plate through the threaded mounting rod to further complete the connection between the pick body and the pick body shank. After connection, the fixing ring on the pick body abuts against the circular mounting plate, and then is connected by a connection bolt. When the pick body is in use, the second spiral cutter on the spiral cutter head first performs spiral cutting until it reaches the first spiral cutter. The first spiral coil and the second spiral coil on the first spiral cutter cooperate to perform cutting, and the cutter surface is completely cut through by the cooperation of the convex inclined surface.
[0004] For this structure, although the cutting performance can be improved, its disassembly and assembly with the machine body are not convenient, resulting in difficult operation when replacing the pick. Therefore, we propose a cermet pick that can quickly disassemble and assemble the pick to make its replacement work more convenient. Content of the Utility Model
[0005] The purpose of the utility model is to provide a cermet pick to solve the problems raised in the above background technique.
[0006] To achieve the above purpose, the utility model provides the following technical solution: A cermet pick, including a mounting frame, an installation pipe is fixedly installed inside the mounting frame, a cermet pick body is clamped outside the installation pipe, and a processing component is arranged below the mounting frame. The processing component includes a disassembly and assembly component arranged below the mounting frame, and a buffer component is arranged below the disassembly and assembly component.
[0007] Preferably, the disassembly and assembly component includes a clamping groove formed on the outer wall of the cermet pick body. A pull rod is slidably arranged inside the installation pipe. A sleeve plate is fixedly installed at the end of the pull rod. A sliding rod is slidably arranged inside the sleeve plate. A limiting ring is fixedly installed on the outer wall of the sliding rod. A first spring is sleeved on the outer wall of the sliding rod. A connecting plate is hingedly connected to the outer wall of the sleeve plate. One end of the connecting plate away from the sleeve plate is hingedly connected to a clamping pin.
[0008] Preferably, the buffer component includes a sliding groove formed on the outer wall of the cermet pick body. A second spring is arranged inside the sliding groove. A limiting plate is slidably arranged inside the sliding groove. A cutting plate is fixedly installed on the outer wall of the limiting plate.
[0009] Preferably, the sleeve plate and the sliding rod are slidably arranged on the outer wall, and the pull rod and the installation pipe are slidably arranged inside. When the sleeve plate slides upward, the first spring sleeved on the outer wall of the sliding rod can be compressed. When the pull rod is not pulled, under the elastic action of the first spring, the sleeve plate is pushed downward. Under the restriction of the limiting ring, the sleeve plate can be blocked and restricted.
[0010] Preferably, the end of the clamping pin is arc-shaped, and the outer wall of the clamping pin is clamped with the inner wall of the clamping groove. Under its restriction, the cermet pick body and the installation pipe can be clamped.
[0011] Preferably, one end of the second spring is fixedly installed on the inner wall of the sliding groove, and the side of the second spring away from the sliding groove is fixedly installed on the outer wall of the limiting plate. Under its restriction, when the cutting plate is not squeezed, the cutting plate can be reset.
[0012] Preferably, the number of the cutting plates is ten, and they are distributed circumferentially around the center of the cermet pick body. Under its restriction, it can assist the cermet pick body during tunneling.
[0013] Compared with the prior art, the beneficial effects of the present utility model are:
[0014] 1. This cermet pick is composed of a disassembly and assembly component as one of its parts. When it is necessary to install the cermet pick body and the installation pipe, align the cermet pick body with the installation pipe, pull the pull rod, so that the pull rod drives the sleeve plate to slide upward. The sleeve plate compresses the first spring sleeved on the outer wall of the sliding rod, so that the sleeve plate drives the connecting plate hingedly connected to its outer wall to move. Since one end of the connecting plate away from the sleeve plate is hingedly connected to the outer wall of the clamping pin, under its restriction, the connecting plate pulls the clamping pin, sleeved the cermet pick body on the outer wall of the installation pipe, align the clamping pin with the clamping groove, release the pull rod, under the elastic action of the first spring, push the sleeve plate downward, the sleeve plate pushes the connecting plate, and push the clamping pin into the clamping groove, so that the clamping pin is clamped with the clamping groove to quickly install the cermet pick body and the installation pipe.
[0015] 2. The cermet pick includes a buffer assembly as one of its components. When the cermet pick body performs tunneling work, the cutting plate slidably arranged inside it can assist in tunneling. When the cutting plate is squeezed, it drives the limit plate to slide into the chute. Under the restriction of the sliding of the cutting plate and the chute, it can prevent the cermet pick body from jamming with the tunneling area. With the assistance of the cutting plate, the tunneling efficiency can be improved. Description of the Drawings

Detailed Embodiments
[0023] For a clearer understanding of the technical features, objectives, and effects of the present utility model, the detailed embodiments of the present utility model will now be described with reference to the accompanying drawings.
[0024] Embodiment 1
[0025] A preferred embodiment of a cermet pick provided by the present utility model is as Figures 1 to 6 shown: A cermet pick includes a mounting frame 1;
[0026] A mounting pipe 3 is fixedly installed inside the mounting frame 1;
[0027] A cermet pick body 2 is clamped outside the mounting pipe 3;
[0028] And a processing component 4 arranged below the mounting frame 1. The processing component 4 includes a disassembly and assembly component 41 arranged below the mounting frame 1. The disassembly and assembly component 41 includes a clamping groove 411 formed on the outer wall of the cermet pick body 2. A pull rod 412 is slidably arranged inside the mounting pipe 3. A sleeve plate 413 is fixedly installed at the end of the pull rod 412. A sliding rod 414 is slidably arranged inside the sleeve plate 413. A limiting ring 415 is fixedly installed on the outer wall of the sliding rod 414. A first spring 416 is sleeved on the outer wall of the sliding rod 414. A connecting plate 417 is hingedly connected to the outer wall of the sleeve plate 413. One end of the connecting plate 417 far from the sleeve plate 413 is hingedly connected to a clamping pin 418.
[0029] In this embodiment, when it is necessary to install the cermet pick body 2 and the mounting pipe 3, align the cermet pick body 2 and the mounting pipe 3, pull the pull rod 412, so that the pull rod 412 drives the sleeve plate 413 to slide upward. The sleeve plate 413 compresses the first spring 416 sleeved on the outer wall of the sliding rod 414, so that the sleeve plate 413 drives the connecting plate 417 hingedly connected to its outer wall to move. Since one end of the connecting plate 417 far from the sleeve plate 413 is hingedly connected to the outer wall of the clamping pin 418, under its restriction, the connecting plate 417 pulls the clamping pin 418, sleeving the cermet pick body 2 on the outer wall of the mounting pipe 3, aligning the clamping pin 418 with the clamping groove 411, releasing the pull rod 412, and under the elastic action of the first spring 416, pushing the sleeve plate 413 downward. The sleeve plate 413 pushes the connecting plate 417, pushing the clamping pin 418 into the clamping groove 411, so that the clamping pin 418 is clamped with the clamping groove 411 to quickly install the cermet pick body 2 and the mounting pipe 3.
[0030] Furthermore, the sleeve plate 413 is slidably arranged on the outer wall of the sliding rod 414, and the pull rod 412 is slidably arranged inside the mounting pipe 3. When the sleeve plate 413 slides upward, the first spring 416 sleeved on the outer wall of the sliding rod 414 can be compressed. When the pull rod 412 is not pulled, under the elastic action of the first spring 416, the sleeve plate 413 is pushed downward, and under the restriction of the limiting ring 415, the sleeve plate 413 can be blocked and restricted.
[0031] Even further, the end of the clamping pin 418 is arranged in an arc shape, and the outer wall of the clamping pin 418 is clamped with the inner wall of the clamping groove 411. Under its restriction, the cermet pick body 2 and the mounting pipe 3 can be clamped.
[0032] Embodiment 2
[0033] On the basis of Embodiment 1, a preferred embodiment of the cermet pick provided by the present utility model is as Figures 1 to 6 shown: The buffer component 42 includes a sliding groove 421 formed on the outer wall of the cermet pick body 2. A second spring 422 is arranged inside the sliding groove 421. A limiting plate 423 is slidably arranged inside the sliding groove 421. A cutting plate 424 is fixedly installed on the outer wall of the limiting plate 423.
[0034] In this embodiment, when the cermet pick body 2 is tunneling, the cutting plate 424 slidably arranged inside it can be used to assist in tunneling. When the cutting plate 424 is squeezed, it drives the limiting plate 423 to slide into the chute 421. Under the restriction of the sliding of the cutting plate 424 and the chute 421, the cermet pick body 2 can be prevented from getting stuck with the tunneling area. With the assistance of the cutting plate 424, the tunneling efficiency can be improved.
[0035] Furthermore, one end of the second spring 422 is fixedly installed on the inner wall of the chute 421, and the other side of the second spring 422 away from the chute 421 is fixedly installed on the outer wall of the limiting plate 423. Under its restriction, when the cutting plate 424 is not squeezed, the cutting plate 424 can be reset.
[0036] In addition, the number of the cutting plates 424 is ten, and they are circumferentially distributed around the center of the cermet pick body 2. Under its restriction, the cermet pick body 2 can be assisted during tunneling.
[0037] The above is only a schematic specific embodiment of the present utility model and is not intended to limit the scope of the present utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of the present utility model shall fall within the scope of protection of the present utility model. Moreover, it should be noted that the components of the present utility model are not limited to the above overall application. Each technical feature described in the specification of the present utility model can be selected and used alone according to actual needs or combined with multiple features. Therefore, the present utility model should logically cover other combinations and specific applications related to the inventive points of this case.
