Description

Technical Field

[0001] The present application relates to the technical field of ore crushing machinery and equipment, and in particular to a hammer crushing equipment. Background Art

[0002] Hammer crusher is mainly used for medium-hard and weakly abrasive materials. When the hammer crusher is working, the motor drives the hammer head to rotate at high speed, and the material in the casing is crushed by the impact, shearing and grinding of the high-speed moving hammer head. The crushing particle size of the hammer crusher can be controlled by the screen plate at the bottom, which can meet the requirements of coarse, medium and fine crushing particle sizes. Since the hammer head hits the material for a long time, the hammer head wears quickly and needs to be replaced regularly. The hammer head of the existing hammer crusher is mainly fixed on the rotor through a connecting shaft, and multiple hammer heads are fixed on the pin shaft at the same time. Since the hammer heads of some small hammer crushers are small, workers can replace multiple hammer heads at a time. However, for some large hammer crushers, the weight of a single hammer head is more than 10kg, and workers can only install them one by one. Moreover, when replacing, due to the problem of weight imbalance, another worker is required to cooperate in fixing the rotor during replacement, resulting in a long replacement process and a large amount of physical energy consumed by the workers. Therefore, a hammer crushing equipment is needed, which can fix the hammer head and the transmission shaft through a special support frame when replacing the hammer head, which can significantly improve the replacement efficiency and reduce the physical energy consumption of the workers. Utility Model Content

[0003] In order to solve the above problems, the present application proposes a hammer crushing equipment, which can fix the hammer head and the transmission shaft through a special support frame when replacing the hammer head, which can significantly improve the replacement efficiency and reduce the physical exertion of workers.

[0004] This application is implemented through the following technical solutions:

[0005] The present application proposes a hammer crushing equipment, including: an upper shell, a lower shell, a transmission shaft, a hammer head, and a support frame, wherein the upper shell is connected to the lower shell by a hinge, and both ends of the transmission shaft are installed in the lower shell by bearing seats, a pulley is provided on one side of the transmission shaft, and circular plates are installed on the transmission shaft at intervals; a pin is provided on the outer side of the circular plate, and one end of the hammer head is installed between the circular plates through the pin; the support frame spans across the two sides of the lower shell along the axial direction of the transmission shaft, and a rubber block is provided at the lower part of the support frame, and the rubber block is pressed on the upper part of the circular plate. After the lower end of the hammer head to be installed passes through the support frame, it extends between the circular plates.

[0006] Furthermore, the support frame includes a first support plate, a second support plate, and support legs, the support legs are installed on both sides of the first support plate, the first support plate is provided with a first opening groove, the second support plate is provided with a second opening groove, and the opening direction of the first opening groove is opposite to the opening direction of the second opening groove.

[0007] Furthermore, the width of the first opening groove is greater than the width of the hammer head, and the width of the second opening groove is smaller than the width of the first opening groove.

[0008] Furthermore, the first opening slot and the second opening slot are staggered with each other, and the hammer head is stuck in the second opening slot.

[0009] Furthermore, a limiting block is provided on the inner side of the supporting foot, and the supporting foot is connected to the lower edge of the lower shell body through the limiting block.

[0010] Furthermore, the lower part of the rubber block is arc-shaped, and the radius of the arc is the same as the outer diameter of the circular plate, and the lower part of the rubber block is tightly attached to the outer circumference of the circular plate.

[0011] The beneficial effects of the present application are as follows: by placing the support frame across the transmission shaft, the support plate can lift the hammer head to be installed, making it convenient for the installation workers to install. At the same time, the lower part of the support frame is pressed on the circular plate by a rubber block, thereby preventing the circular plate from rotating through friction, and ensuring the stability of the circular plate when installing the pin shaft, so that the pin shaft can pass through the circular plate and the hammer head in turn, which can significantly improve the replacement efficiency and reduce the physical exertion of the workers.

DETAILED DESCRIPTION

[0015] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. Obviously, the described embodiments are only a part of the embodiments of the utility model, not all of them.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0018] like Figure 1 to Figure 2 As shown, an embodiment of the utility model provides a hammer crushing device, including: an upper shell 1, a lower shell 2, a transmission shaft 3, a hammer head 4, and a support frame 5. The upper shell 1 is connected to the lower shell 2 by a hinge, and both ends of the transmission shaft 3 are installed in the lower shell 2 through bearing seats 6. A pulley 7 is provided on one side of the transmission shaft 3, and circular plates 8 are installed on the transmission shaft 3 at intervals; a pin shaft 9 is provided on the outer side of the circular plate 8, and one end of the hammer head 4 is installed between the circular plates 8 through the pin shaft 9; the support frame 5 spans across both sides of the lower shell 2 along the axial direction of the transmission shaft 3, and a rubber block 10 is provided at the lower part of the support frame 5. The rubber block 10 is pressed on the upper part of the circular plate 8, and the lower end of the hammer head 4 to be installed passes through the support frame 5 and extends between the circular plates 8.

[0019] When the hammer 4 of the crushing equipment needs to be replaced, the locking bolts between the upper shell 1 and the lower shell 2 are opened, and then the upper shell 1 is opened to expose the circular plate 8. When replacing, the limit pin at the end of the pin shaft 9 is loosened, and the worn hammer 4 is taken out while the pin shaft 9 is pulled out. At this time, the circular plate 8 will rotate to the highest point on the side of the hammer 4 removed under the pull of the gravity of the other hammers 4. The worker places the support frame 5 on the circular plate 8, and the rubber block 10 at the bottom of the support frame 5 is pressed on the outer periphery of the circular plate 8. Under the action of the gravity of the middle support frame 5 and the hammer 4, the rubber block 10 squeezes the circular plate 8, generating The friction force prevents the circular plate 8 from rotating. The worker inserts the connecting section of the hammer head 4 to be installed into the first opening slot 14, and pushes the second support plate 12 at the same time, and clamps the middle part of the hammer head 4 through the second opening slot 15, so that the hammer head 4 is limited on the support frame 5. After multiple hammer heads 4 are placed, the pin shaft 9 is passed through the circular hole of the circular plate 8, and the pin shaft 9 passes through the through hole at the bottom of the hammer head 4, and then the hammer head 4 is locked between the circular plates 8. After the hammer heads 4 are installed, the second support plate 12 is pulled out to separate the hammer heads 4 from the support frame 5, so as to facilitate the replacement of the next group of hammer heads 4. The support frame 5 can hold multiple hammer heads 4 at a time, reduce the labor intensity of workers when replacing hammer heads and fine-tuning positions, and facilitate the replacement of hammer heads 4. The rubber block 10 can prevent the circular plate 8 from rotating through friction, and facilitate the pin shaft 9 to quickly pass through the circular plate 8, thereby increasing the installation speed.

[0020] Specifically, Figure 2 As shown, the support frame 5 includes a first support plate 11, a second support plate 12, and a support leg 13. The support leg 13 is installed on both sides of the first support plate 11. The first support plate 11 is provided with a first opening groove 14, and the second support plate 12 is provided with a second opening groove 15. The opening direction of the first opening groove 14 is opposite to the opening direction of the second opening groove 15. The hammer head 4 is supported by the first support plate 11 and the second support plate 12, so that multiple hammer heads 4 can be suspended above the circular plate 8 at the same time, which is convenient for installing multiple hammer heads at one time, and no workers are required to lift during installation, which reduces the physical exertion of workers.

[0021] In a preferred embodiment, the width of the first opening groove 14 is greater than the width of the hammer head 4, which facilitates the hammer head 4 to slide out of the first opening groove 14. The width of the second opening groove 15 is less than the width of the first opening groove 14. The second opening groove 15 is mainly used to be stuck in the step of the hammer head 4, thereby fixing the hammer head 4 on the support frame 5 to achieve lifting of the hammer head 4.

[0022] In a specific embodiment, the first opening groove 14 and the second opening groove 15 are staggered with each other, and the hammer head 4 is stuck in the second opening groove 15. The second opening groove 15 is mainly used to be stuck at the step of the hammer head 4 to limit the hammer head 4. After the hammer head 4 is installed and the second support plate 12 is pulled out, the hammer head 4 can pass through the first opening groove 14 and be separated from the support frame 5.

[0023] Preferably, a limit block 16 is provided inside the support foot 13 , and the support foot 13 is connected to the lower edge of the lower shell 2 via the limit block 16 . The support foot 13 can ensure that the first support plate 11 and the second support plate 12 remain stable to avoid tipping over.

[0024] In a specific embodiment, the lower portion of the rubber block 10 is arc-shaped, and the radius of the arc is the same as the outer diameter of the circular plate 8. The lower portion of the rubber block 10 is tightly attached to the outer circumference of the circular plate 8. When the first support plate 11 and the second support plate 12 lift the hammer head 4, the rubber block 10 is affected by the gravity of the hammer head 4 and will be pressed on the outer circumference of the circular plate 8, thereby generating damping, so that the circular plate 8 remains stable, making it easier for the pin shaft 9 to pass through the circular plate 8 and the hammer head 4.

[0025] Of course, the present application may have many other implementations. Based on the present implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present application.
