Description

Technical Field

[0001] This utility model relates to the field of hammer crusher technology, and in particular to a hammer crusher that improves crushing efficiency. Background Technology

[0002] An ore crusher is a type of crushing machinery that uses impact energy to crush ore materials.

[0003] The prior art disclosure number CN215197288U describes a hammer crusher for improving crushing efficiency, which includes a support frame, a crusher, a tilting assembly, and a screening assembly. The crusher is located on the top of the support frame, the tilting assembly is located on the inner wall of the support frame, and the screening assembly is located on the side wall of the support frame and connected to the tilting assembly.

[0004] The shortcomings of the existing technology are that adding crushed ore into the crusher requires manual addition or additional mechanical equipment (such as a loader). A loader cannot guarantee that the crushed stone is completely added into the crusher, especially for small crushers. Manual addition of crushed stone requires lifting the crushed stone to a certain height before it can be added into the crusher, which greatly increases the workload of workers. Therefore, this application proposes a hammer crusher to improve crushing efficiency. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a hammer crusher that improves crushing efficiency.

[0006] An embodiment of this utility model provides a hammer crusher for improving crushing efficiency, comprising:

[0007] A base on which a crushing shell is mounted;

[0008] The crushing structure includes a rotating column rotatably installed inside the crushing shell, the rotating column having multiple annular grooves, a crushing hammer rotatably connected within the annular grooves, and a crushing head fixed at one end of the crushing hammer.

[0009] The feeding structure includes a tipping hopper rotatably mounted on the crushing shell, and an electric push rod is installed on the base to drive the tipping hopper to tilt, so that the tipping hopper can correspond to the crushing shell.

[0010] Furthermore, a discharge chute is provided through the base, and an arc-shaped mesh plate opposite to the discharge chute is installed at the bottom of the crushing shell.

[0011] Furthermore, it also includes a drive mechanism, which includes a motor mounted on the base. The motor is connected to the rotating column through a transmission structure. The transmission structure includes two transmission wheels fixed to the output end of the motor and the rotating column. The two transmission wheels are connected by a transmission belt.

[0012] Furthermore, a support plate is mounted on the base, and the electric push rod is mounted on the support plate.

[0013] Furthermore, brackets are installed on both the tipping hopper and the support plate, and mounting blocks are rotatably mounted on the brackets. The two ends of the electric push rod are fixedly connected to the mounting blocks.

[0014] Furthermore, brackets are installed on both the tipping hopper and the support plate, and mounting blocks are rotatably mounted on the brackets. The two ends of the electric push rod are fixedly connected to the mounting blocks.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This invention features a rotatable breaker hammer, which adapts to the size or hardness of the crushed stone, eliminating the need for hammer adjustment and improving crushing efficiency. An electric push rod drives the tipping hopper to tilt, and the crushed stone eventually slides into the crushing shell due to gravity, thus feeding the stone and reducing the workload of workers while increasing work efficiency.

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0023] like Figures 1-4 As shown in the figure, this utility model embodiment proposes a hammer crusher for improving crushing efficiency, comprising:

[0024] The base 1 has a discharge chute 7 running through it. A crushing shell 2 is installed on the base 1. An arc-shaped mesh plate 13 is installed at the bottom of the crushing shell 2, which is opposite to the discharge chute 7. The mesh plate 13 can screen the crushed stone. The crushed stone passing through the mesh plate 13 is discharged through the discharge chute 7 so that the crushed stone can be removed. For the small equipment of this application, a drop chute can be dug in the ground, and workers can remove the crushed stone chips from one side. The base 1 is placed on the ground with the discharge chute 7 opposite to the drop chute; or it can be placed on a corresponding support to remove the crushed stone chips.

[0025] The crushing structure includes a rotating column 9 rotatably installed inside the crushing housing 2, and a drive mechanism. The drive mechanism includes a motor 6 mounted on the base 1. The motor 6 is connected to the rotating column 9 through a transmission structure 8. The transmission structure includes two transmission wheels fixed to the output end of the motor 6 and the rotating column 9. Both the rotating column 9 and the output end of the motor 6 are equipped with short shafts to accommodate the transmission wheels. The two transmission wheels are connected by a transmission belt and are of different sizes. The motor 6 operates through the transmission structure 8, enabling the rotating column 9 to rotate.

[0026] The rotating column 9 is provided with multiple annular grooves 10, and a breaker hammer 11 is rotatably connected within each annular groove 10. The multiple breaker hammers 11 are arranged in a circular array within the annular grooves 10. A breaker head 12 is fixed to one end of each breaker hammer 11. Figure 3 As shown, the motor 6 drives the rotating column 9 to rotate clockwise. Due to centrifugal force, the breaker hammer 11 and the breaker head 12 will move away from the rotating column 9 and tend to a stable state. When the crushed stone enters the crushing shell 2, the breaker hammer 11 and the breaker head 12 rotate. The breaker head 12 can crush the crushed stone and at the same time convey the crushed stone into the crushing shell 2.

[0027] Since the hydraulic breaker 11 is rotated, when it impacts a large rock, if it cannot break the rock, the resistance will cause the hydraulic breaker 11 to rotate, thus protecting the hydraulic breaker 11 and preventing damage or breakage caused by hard impact. In this way, the hydraulic breaker 11 also has the effect of adapting to the size or hardness of the crushed stone, without the need to adjust the hydraulic breaker 11, which can improve the crushing efficiency of crushed stone.

[0028] The breaker hammer 11 and the breaker head 12 are positioned close to the screen plate 13 and do not collide with each other when they rotate. Therefore, the crushed stone that has not passed through the screen plate 13 can be further crushed, realizing the cyclic crushing of the crushed stone until it can fall through the screen plate 13, thus achieving better results.

[0029] The feeding structure includes a tipping hopper 3 rotatably mounted on the crushing shell 2, an electric push rod 5 for driving the tipping hopper 3 to tilt on the base 1, a support plate 4 mounted on the base 1, the electric push rod 5 mounted on the support plate 4, brackets mounted on both the tipping hopper 3 and the support plate 4, mounting blocks rotatably mounted on the brackets, and the two ends of the electric push rod 5 fixedly connected to the mounting blocks so that the tipping hopper 3 can correspond to the crushing shell 2. Workers only need to shovel the crushed stone into the tipping hopper 3, reducing the height of manual feeding. Then, the electric push rod 5 drives the tipping hopper 3 to tilt, and finally the crushed stone slides into the crushing shell 2 due to gravity, realizing the feeding of crushed stone, reducing the workload of workers and improving work efficiency.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
