Description

Technical Field

[0001] This utility model relates to the technical field of material crushing, specifically a hammer head for a crusher with adjustable cutting surface. Background Technology

[0002] A crusher is a machine that crushes large solid raw materials to the required size.

[0003] Existing crushers use a combination of cutters and toothed rings to crush materials. The crushing motion involves relative movement between the cutters and the toothed ring. The cutters are typically mounted on a turntable driven by a motor, rotating at high speed. The toothed ring can be stationary or rotating at low speed. When material enters the area between the cutters and the toothed ring, the high-speed rotation of the cutters and the relative stationary or low-speed rotation of the toothed ring generate shearing force, thereby crushing the material.

[0004] However, since the cutter head is in continuous contact with the material, the material-facing surface of the cutter head will wear down under a certain period of crushing environment, resulting in the material not being crushed to the required crushing effect. Therefore, the cutter head needs to be replaced regularly. However, since some existing cutter heads only have one cutting bevel, their service life is relatively short, which increases production costs. Utility Model Content

[0005] The purpose of this invention is to provide a chip-face adjustable crusher hammer to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a chip-face adjustable crusher hammer head, comprising a hammer head body, wherein multiple hammer head bodies are detachably mounted on a crushing disc along the circumferential direction; the hammer head body includes a cutter head and a mounting component connected to the cutter head, the mounting component being used to connect to the crushing disc; the extended line of the length direction of the cutter head intersects the axis of the crushing disc, and four cutting surfaces are formed on the cutter head, the planes of the four cutting surfaces forming a rhombus shape.

[0007] As described above, the chip-face adjustable pulverizer hammer head includes a locking post fixed to the cutter head and a threaded post fixed to the locking post. The locking post and the threaded post pass through the mounting groove on the pulverizing disc and are fixed by a nut.

[0008] As described above, the chip-face adjustable crusher hammer head includes a locking column comprising a connecting column and a limiting connector that are connected to each other. The connecting column is fixed to the cutter head, and the limiting connector is fixed to the threaded column. The diameter of the connecting column is larger than the diameter of the limiting connector.

[0009] As described above, the chip-face adjustable pulverizer hammer has two symmetrical locking positions on the limiting connector. The locking positions are planar and are used to engage with the through grooves formed on the pulverizing disc.

[0010] As described above, the chip-face adjustable crusher hammer head has the following characteristics: the length of the cutter head is 94mm ± 0.2mm, the height of the cutter head is 25mm ± 0.2mm, and the thick end of the cutter head is tangent to the threaded post in a circle with a radius of 15mm ± 0.2mm.

[0011] As described above, the chip-face adjustable pulverizer hammer head has a connecting column that is a cylinder with a thickness of 11.5mm ± 0.2mm.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The cutter head is equipped with four cutting surfaces. When the cutter head is installed on the crushing disc, the crushing disc rotates in one direction, thereby utilizing one cutting surface in conjunction with the gear ring to crush the material. When the current cutting surface wears down, the crushing disc can be controlled to rotate in the opposite direction, allowing another cutting surface to be used in conjunction with the gear ring to crush the material. The two cutting surfaces located towards the center of the crushing disc guide the material towards the center of the crushing disc, which is beneficial for the flow of fine particles. When both cutting surfaces located opposite the center of the crushing disc wear down, the cutter head can be installed in the opposite direction, allowing the two cutting surfaces originally facing the center of the crushing disc to be used for cutting. This fully utilizes the multiple cutting surfaces of the cutter head, reducing the frequency of cutter head replacement and lowering operating costs. Furthermore, the four cutting surfaces allow the cutter head to crush material in both forward and reverse rotation directions, improving the flexibility and applicability of the crusher and making it highly practical.

[0020] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0021] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0022] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0023] This utility model aims to provide a hammer for a mechanical crusher. The hammer is mounted on a crushing disc 2, which is connected to a drive shaft. When the drive shaft rotates, it drives the crushing disc 2 and the hammer to rotate synchronously. The end of the hammer protrudes from the crushing disc 2 and engages with a toothed ring on the inner wall of the crusher to crush materials. The specific implementation of the hammer is as follows: Please refer to [link / reference]. Figures 1-6 In this embodiment of the present invention, a chip-face adjustable crusher hammer head includes a hammer head body 1, and a plurality of hammer head bodies 1 are detachably mounted on a crushing disc 2 along the circumferential direction; the hammer head body 1 includes a cutter head 11 and a mounting component connected to the cutter head 11, the mounting component being used to connect the crushing disc 2; the extended line of the length direction of the cutter head 11 intersects the axis of the crushing disc 2, and four cutting surfaces 1101 are formed on the cutter head 11, the planes in which the four cutting surfaces 1101 are located enclose a rhombus shape.

[0024] The cutter head 11 is equipped with four cutting surfaces 1101. When the cutter head 11 is installed on the crushing disc 2, the crushing disc 2 rotates in one direction, thereby using one of the cutting surfaces 1101 to cooperate with the gear ring to crush the material. When the current cutting surface 1101 wears down, the crushing disc 2 can be controlled to rotate in the opposite direction, thereby using another cutting surface 1101 to cooperate with the gear ring to crush the material. The two cutting surfaces 1101 located towards the center of the crushing disc 2 guide the material towards the center of the crushing disc 2, which is beneficial to the flow of fine particles. When the two cutting surfaces 1101 located opposite the center of the crushing disc 2 wear down, the cutter head 11 can be installed in the opposite direction, so that the two cutting surfaces 1101 originally facing the center of the crushing disc 2 are used for cutting action, thereby making full use of the multiple cutting surfaces of the cutter head 11, reducing the frequency of cutter head replacement, and reducing the operating cost. In addition, the setting of four cutting surfaces 1101 allows the cutter head 11 to crush materials in both the forward and reverse rotation directions, improving the flexibility and applicability of the crusher and making it highly practical.

[0025] It should be noted that the hammerhead body 1 is made of zirconium oxide in one piece, which has high hardness, simple structure, convenient use and installation, long service life, and low operating cost.

[0026] Further, please refer to Figures 1-4 The mounting component includes a locking post fixed to the cutter head 11 and a threaded post 14 fixed to the locking post. The locking post and the threaded post 14 pass through the mounting groove on the crushing disc 2 and are fixed by a nut. The locking post includes a connecting post 12 and a limiting connector 13 connected to each other. The connecting post 12 is fixed to the cutter head 11, and the limiting connector 13 is fixed to the threaded post 14. The diameter of the connecting post 12 is larger than the diameter of the limiting connector 13.

[0027] The connecting post 12 is designed to block material when the threaded post 14 and the limiting connector 13 pass through the crushing disc 2, preventing material from falling into the threaded post 14 and affecting the normal operation of the equipment. It should be noted that a cylindrical cavity is provided on the crushing disc 2 for placing the connecting post 12, so that the side of the cutter head 11 facing the crushing disc 2 can maintain a tight fit with the crushing disc 2.

[0028] To improve the stability of the blade head 11 installation, two locking positions 1301 are symmetrically formed on the limiting connector 13. The locking positions 1301 are planar and are used to engage with the through groove formed on the crushing disc 2. Preferably, the crushing disc 2 is provided with a slot for the limiting connector 13 to be inserted and whose shape is adapted to the shape of the limiting connector post 12. This is used to achieve circumferential limiting of the limiting connector 13 and prevent the blade head 11 from deflecting circumferentially during use, which would lead to a deterioration in the material crushing effect. At the same time, the locking positions 1301 are symmetrically arranged so that after the limiting connector 13 rotates 180° and is reinserted into the slot and fixed, the blade head 11 undergoes a 180° position adjustment, thereby enabling the use of the other two cutting bevels 1101 of the blade head 11.

[0029] It should be noted that the length of the cutter head 11 is 94mm ± 0.2mm, the height of the cutter head 11 is 25mm ± 0.2mm, the thick end of the cutter head 11 is tangent to the threaded post 14 in a circle with a radius of 15mm ± 0.2mm, and the connecting post 12 is a cylinder with a thickness of 11.5mm ± 0.2mm, where the thickness of the connecting post 12 is its length along the axial direction.

[0030] Of course, the above-mentioned size limitation is merely an example of one embodiment. In the specific implementation process, it can be adjusted according to the actual use needs. This embodiment does not make specific limitations in this regard.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0032] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
