Description

Hammer, rotor assembly and crushing device

Technical Field

The invention relates to the technical field of crushing machinery, in particular to a hammer, a rotor assembly and a crushing device.

Background

The hammer slice is a mechanical part commonly used by people when crushing materials, and the striking end of the existing hammer slice is usually designed into a right angle or a knife edge so as to crush the materials.

Mulch is a class of materials used for soil surface protection and improvement of ground surface conditions, including: inorganic covers and organic covers. The inorganic mulch can degrade soil aeration and affect plant growth. The organic covering is mainly made of wood, such as waste branches, and the organic covering is covered on the exposed ground surface after being crushed and dyed, so that the effects of improving soil and beautifying the environment are achieved. The morphology of the covering directly affects the production efficiency, the use effect and the visual effect of the covering.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Fig. 1 is a schematic structural diagram of a hammer 100 according to an embodiment of the present invention. As shown in fig. 1, the hammer blade 100 includes: a working portion 110 and a connecting portion 120.

The working portion 110 comprises a working face 111 for crushing material as the blade 100 rotates with the rotor of the crushing device. The connecting portion 120 is used for connecting with the rotor to drive the working portion 110 to rotate with the rotor. The working portion 110 further comprises a chamfer 112, the chamfer 112 is arranged at the end portion, far away from the connecting portion 120, of the working portion 110 and used for crushing materials when the hammer 100 rotates along with the rotor, and the width of the working surface is larger than or equal to 15mm and smaller than or equal to 20 mm.

Specifically, the hammer 100 is connected with the rotor through the connecting part 120, the rotor can drive the hammer 100 to rotate when in operation, the working surface 111 of the hammer 100 can beat and crush materials due to a large speed difference between the hammer 100 and the materials, and due to the chamfer design of the embodiment of the invention, the working part is in surface contact with the materials when the working part beats and crushes the materials, so that the effect of crushing the materials in a hammering mode is achieved, and a product with a fibrous part can be obtained.

Specifically, the shape of the hammer 100 may be a rectangular parallelepiped, wherein the working surface 111 is a first side surface, a second side surface of the hammer 100 is parallel to the working surface 111, the first surface and the second surface of the hammer 100 are parallel to each other and are both perpendicular to the rotation central axis of the hammer 100, a third side surface and a fourth side surface of the hammer 100 are parallel to each other, the third side surface is a side surface far away from the connecting portion, and the fourth side surface is a side surface close to the connecting portion. The chamfer 112 is a transition surface between the working surface 111 and the third side surface, so that when the hammer 100 impacts and hammers the material, the chamfer 112 can prevent the corner between the working surface 111 and the third side surface from crushing the material in a crushing manner, so as to achieve the hammering effect on the material, and thus a product with a certain shape can be obtained. The shape of the chamfer 112 may be set according to the actual situation. Further, a chamfer may be disposed between the second side and the third side, so that the working portion 110 has two working surfaces, and when one working surface is worn, the mounting position of the hammer is reversed, so that the other working surface works, thereby improving the utilization rate of the hammer 100.

Specifically, the connection portion 120 may include a through hole penetrating the first and second surfaces of the hammer blade 100, or protrusions provided on the first and second surfaces, respectively, near the fourth side for connection with the rotor.

Further, since the portion of the working surface 111 near the third side surface is more worn than the portion near the fourth side surface when the hammer blade 100 is used, a connecting portion corresponding to the connecting portion 120 may be provided near the third side surface in order to improve the usage efficiency of the hammer blade 100. Thus, when the chamfer 112 or the part of the working face 111 close to the third side surface is seriously worn, the connecting part close to the third side surface can be connected with the rotor so as to crush the material by utilizing the part of the working face 111 close to the fourth side surface, and at the moment, the chamfer can be arranged between the working face 111 and the fourth side surface so as to realize the same crushing effect. Optionally, the chamfer angle between the working surface 111 and the fourth side surface may be the same as the chamfer angle 112, or may be different or not provided, so as to be suitable for different materials or achieve different crushing effects.
