Description

Technical Field

[0001] The utility model relates to the technical field of crusher hammers, and specifically relates to a hammer for a horizontal shaft impact crusher. Background Art

[0002] A hammer crusher is a device that crushes materials by impact. There are several rows of hanging hammer bodies installed on the horizontal main shaft inside the crusher. The hammer body is composed of a hammer disc and a hammer head, and can crush large-grained materials into small-grained materials, and is suitable for medium crushing and fine crushing operations of materials such as limestone, slag, and coal.

[0003] However, the hammers of existing horizontal shaft impact crushers are usually fixed on the hammer disc through pin shafts and locking nuts. When the horizontal shaft drives the hammers on the hammer disc to rotate, the horizontal shaft needs to be raised to a relatively high speed, resulting in high energy consumption during the use of the crusher; in addition, when disassembling the hammers of existing impact crushers, the hammer disc needs to be removed first before the hammers fixed on the hammer disc can be disassembled, resulting in a longer time-consuming process for replacing the worn hammers. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a hammer for a horizontal shaft impact crusher to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A hammer for a horizontal shaft impact crusher, including a hammer body. A sliding ring is provided at the bottom of the hammer body. A clamping column is movably inserted through the middle of the sliding ring. One end of the clamping column is fixed with a second chuck. A cylinder is fixedly connected to the middle of the second chuck. A horizontal shaft passes through the middle of the cylinder. The horizontal shaft is rotationally connected to the crusher. External threads are provided on the outer wall of the cylinder. A first chuck is provided outside the external threads. Four notches are provided on the outer wall of the first chuck. Internal threads are provided on the inner wall of the first chuck.

[0006] Preferably, a counterweight is fixedly connected to the top end of the hammer body, and a hammer handle is fixedly connected to the bottom end of the hammer body.

[0007] Preferably, the sliding ring is fixedly connected to the hammer handle, and the sliding ring is fixedly connected to the hammer body through the hammer handle.

[0008] Preferably, the internal threads are movably connected to the external threads. The first chuck is movably threadedly connected to the external threads through the internal threads, and the first chuck is movably threadedly connected to the cylinder through the external threads.

[0009] Preferably, the first chuck is movably connected to the second chuck through the cylinder, and the clamping column is movably connected to the notch through the second chuck.

[0010] Preferably, one end of the clamping column is fixedly connected with a rubber pad, and the rubber pad is movably connected to the first chuck through the clamping column.

[0011] Preferably, the cylinder and the hammer body are movably connected to the crusher via a horizontal axis.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The hammer head used for the horizontal shaft impact crusher can be mounted on the horizontal shaft in a swingable state through a clamping column, a first chuck, a second chuck and a counterweight head, so that when the horizontal shaft is driven to rotate, the hammer head can swing along the clamping column with the inertia generated after the horizontal shaft rotates, so as to increase the kinetic energy obtained by the hammer head, thereby effectively slowing down the rotation speed of the horizontal shaft driving the hammer head to rotate, and reducing the energy consumption of the crusher during operation.

[0014] 2. The hammer head used for the horizontal shaft impact crusher has external threads, internal threads, notches and slip rings, so that when the worn hammer head is removed from the horizontal shaft, it is only necessary to twist the first chuck so that the notch on the first chuck is aligned with the clamping column on the second chuck with the hammer head, so that one end of the clamping column is opened, and then the hammer head is pulled out from the opened end of the clamping column through the slip ring, thereby reducing the difficulty of disassembling the hammer head and saving the time spent on replacing the worn hammer head.

[0025] Such as Figures 1 to 6As shown in the figure, the hammer head of the present embodiment is used for a horizontal shaft impact crusher, including a hammer body 2. The hammer body 2 is made of diamond material, with high hardness and wear resistance, and can effectively strike the materials entering the crusher 1. A slip ring 14 is provided at the bottom of the hammer body 2. The inner diameter of the slip ring 14 is adapted to the inner diameter of the clamping post 7, so that the slip ring 14 can slide and rotate on the outer wall of the clamping post 7, thereby realizing the swinging of the hammer head due to inertia. A clamping post 7 is movably inserted through the middle of the slip ring 14. The function of the clamping post 7 is to limit the hammer head, so that the moving range of the hammer head is only within the length where the clamping post 7 is located, increasing the stability of the hammer head during swinging. One end of the clamping post 7 is fixed with a second chuck 8. The outer diameter of the second chuck 8 is adapted to the outer diameter of the first chuck 3, so that the end of the clamping post 7 can fit against the side wall of the first chuck 3, thereby realizing the limitation of the hammer head. A cylinder 4 is fixedly connected to the middle of the second chuck 8. The function of the cylinder 4 is to fix the first chuck 3 and the second chuck 8, thereby increasing the stability of the first chuck 3 and the second chuck 8. A horizontal shaft 5 passes through the middle of the cylinder 4. The horizontal shaft 5 is a driving shaft, and the horizontal shaft 5 is rotationally connected to the crusher 1. The shaft end of the horizontal shaft 5 is connected to the output end of the driving mechanism on the crusher 1. External threads 9 are provided on the outer wall of the cylinder 4. The external threads 9 can enable the first chuck 3 to engage with it through internal threads 11, thereby realizing the screwing of the first chuck 3 on the cylinder 4. The first chuck 3 is provided outside the external threads 9. When the first chuck 3 is pressed against the clamping post 7 on the second chuck 8, the position of the notch 6 is in a misaligned relationship with the position of the clamping post 7 sleeved with the hammer body 2 in the initial state, so that both ends of the clamping post 7 sleeved with the hammer body 2 are in a closed state. Four notches 6 are provided on the outer wall of the first chuck 3. The diameter of the notch 6 is larger than the diameter of the slip ring 14, so that the slip ring 14 can smoothly slide from the clamping post 7 into the notch 6 and then slide out of the notch 6, thereby realizing the rapid disassembly of the worn hammer head and facilitating the replacement of the severely worn hammer head. Internal threads 11 are provided on the inner wall of the first chuck 3. After the internal threads 11 and the external threads 9 are tightened, the first chuck 3 is fixed to the cylinder 4. At the same time, the first chuck 3 will be pressed against one side of the second chuck 8, so that both ends of the clamping post 7 sleeved with the hammer body 2 can remain in a closed state, thereby realizing the limitation of the hammer head.

[0026] Specifically, a counterweight 12 is fixedly connected to the top end of the hammer body 2, and a hammer handle 13 is fixedly connected to the bottom end of the hammer body 2. The function of the counterweight 12 is to increase the mass of the top end of the hammer body 2, thereby increasing the inertia of the swinging of the hammer body 2. The hammer handle 13 can extend the length of the hammer body 2, thereby facilitating a larger swing of the hammer body 2, and further obtaining more kinetic energy through inertia.

[0027] Furthermore, the slip ring 14 is fixedly connected to the hammer handle 13. The slip ring 14 is fixedly connected to the hammer body 2 through the hammer handle 13. The slip ring 14 can connect the hammer handle 13 to the clamping post 7, and at the same time enable the hammer handle 13 to be quickly removed from the clamping post 7, thereby facilitating the replacement of the severely worn hammer body 2.

[0028] Further, the internal thread 11 is movably connected to the external thread 9. The first chuck 3 is movably threadedly connected to the external thread 9 through the internal thread 11, and the first chuck 3 is movably threadedly connected to the cylinder 4 through the external thread 9. When needed, the first chuck 3 can rotate along the external thread 9 on the cylinder 4 by engaging, so that the notch 6 on the first chuck 3 can coincide with one end of the clamping post 7 on the second chuck 8, thereby realizing the opening of one end of the clamping post 7.

[0029] Further, the first chuck 3 is movably connected to the second chuck 8 through the cylinder 4, and the clamping post 7 is movably connected to the notch 6 through the second chuck 8. The clamping post 7 sleeved with the hammer body 2 can remove the slip ring 14 from the clamping post 7 through the notch 6, thereby realizing the replacement of the worn hammer head.

[0030] Furthermore, a rubber pad 10 is fixedly connected to one end of the clamping post 7. The rubber pad 10 is movably connected to the first chuck 3 through the clamping post 7. The function of the rubber pad 10 is to reduce the friction generated when the clamping post 7 contacts the first chuck 3, thereby reducing the wear of the clamping post 7 and the first chuck 3.

[0031] The usage method of this embodiment is as follows: Before using the hammer head for the horizontal shaft 5 impact crusher 1, it is necessary to first install this hammer head in the impact crusher 1. When the crusher 1 is running, the horizontal shaft 5 will drive the cylinder 4 to rotate, driving the first chuck 3 and the second chuck 8 to rotate. At this time, the hammer body 2 on the clamping post 7 between the first chuck 3 and the second chuck 8 will pass through the slip ring 14, so that the hammer handle 13 and the counterweight 12 will swing due to inertia under the action of rotation, so that the hammer body 2 obtains kinetic energy other than rotation, so that the cylinder 4 can drive the hammer body 2 at a lower rotational speed to crush the materials entering the crusher 1, so that the energy consumption of the crusher 1 during operation is lower. When it is necessary to replace the severely worn hammer body 2, the first chuck 3 can be screwed, so that the internal thread 11 on the inner wall of the first chuck 3 rotates along the external thread 9 on the outer wall of the cylinder 4 by engaging. When the notch 6 on the first chuck 3 rotates to coincide with one end of the clamping post 7, one end of the clamping post 7 with the rubber pad 10 is opened. The slip ring 14 can be slid along one end of the rubber pad 10 of the clamping post 7, so that the slip ring 14 drives the hammer handle 13 to slide from the clamping post 7 into the notch 6 and then slide out from the other side of the notch 6. At this time, the hammer body 2 is disassembled from the clamping post 7 through the hammer handle 13, so that the worn hammer body 2 is removed. Finally, the reverse operation can be performed. The new hammer body 2 is sleeved on the clamping post 7, and then the first chuck 3 is reset.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
