Description

Technical Field

[0001] The utility model relates to the technical field of crushing equipment, in particular to a tool changing mechanism for an efficient crusher. Background Technique

[0002] A crusher is a machine that crushes large-sized solid raw materials into required sizes. The crusher consists of devices such as coarse crushing, fine crushing, and pneumatic conveying, and achieves the purpose of the crusher in the form of high-speed impact. Small crushers are mainly applicable to the crushing and processing of materials in industries such as food, chemical industry, medicine, greening, and environmental sanitation. During the crushing process, the external forces applied to the materials are rolling, shearing, impact and grinding. In daily life, people often use crushers to crush garbage, feed, and waste, etc.

[0003] For example, the utility model with the application number CN201820942252.X discloses a cutter shaft of a crusher that is convenient for replacing blades. By processing a communicating first smooth through hole and a second smooth through hole on the blade mounting seat, and processing a third smooth through hole on the blade, the blade is screwed and fixed on the blade mounting seat through the threaded engagement between the screw hole in the cylindrical plug in the first smooth through hole and the fixing bolt, avoiding directly tapping threads on the blade and the blade mounting seat. When the thread slips, only the tapped cylindrical plug and the fixing bolt need to be replaced, which is convenient to operate and has a low renewal cost, greatly prolonging the service life of the cutter shaft; secondly, the shape and structure of the blade mounting seat are variable, and different blade densities can be installed, expanding the use range of the crusher.

[0004] The following deficiencies still exist in the current applications similar to the above:

[0005] Most of the cutting tools of crushers are integral structures. After being worn, the entire tool body needs to be replaced, resulting in relatively large waste.

[0006] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a tool changing mechanism for an efficient crusher is proposed. Content of the Utility Model

[0021] The following further describes in detail the embodiments of the present utility model in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0022] As Figure 1 and Figure 2 shown, a tool changing mechanism of an efficient crusher includes a first cutter disc 1. A second cutter disc 2 is connected to the rear end of the first cutter disc 1. Blades 3 are fixedly connected to the outer sides of the first cutter disc 1 and the second cutter disc 2 by bolts. A cutting knife 4 is arranged on one side of the blade 3. The first cutter disc 1 and the second cutter disc 2 are spirally distributed. The structural dimensions of the first cutter disc 1 and the second cutter disc 2 are in line with each other. The multiple cutter discs of the entire crusher are all installed in a circular spiral manner, so that when in use, the materials to be crushed can be comprehensively crushed in this way, improving the crushing effect. At the same time, through the installation method of splicing multiple cutter discs, it is easy to disassemble, replace or maintain a single worn cutter disc, avoiding the replacement of the whole tool. Outer rubber plugs 6 are fixedly connected to the outer ends of the front and rear sides of the bottom end of the first cutter disc 1 and the second cutter disc 2. Inner rubber plugs 8 are fixedly connected to the middle parts of the front and rear sides of the bottom end of the first cutter disc 1 and the second cutter disc 2. Convex teeth 7 are arranged between the outer rubber plugs 6 and the inner rubber plugs 8. The convex teeth 7 are annularly and equidistantly distributed on the surfaces of the first cutter disc 1 and the second cutter disc 2. The first cutter disc 1 and the second cutter disc 2 are snap-connected through the convex teeth 7. When the first cutter disc 1 and the second cutter disc 2 are attached to each other, they are misaligned and snap-connected through the convex teeth 7, making it difficult for two adjacent cutter discs to slide by themselves, thereby ensuring the stability of the placement and installation of the cutter discs. Correspondingly, the outer rubber plugs 6 and the inner rubber plugs 8 are also attached between adjacent cutter discs, which can not only effectively increase the frictional resistance between the cutter discs, prevent self-sliding and reduce wear, but also receive the installation of fixing parts such as fixing pins 5 through the inner rubber plugs 8, and block the invasion and blockage of the outer crushed materials through the outer rubber plugs 6.

[0023] As Figure 1 and Figure 3A fixing pin 5 is connected to the upper end of the first cutter head 1 shown. The lower end of the fixing pin 5 is integrally connected with a pin rod 9, and the pin rod 9 passes through the middle parts of the first cutter head 1 and the second cutter head 2. The bottom end of the pin rod 9 is fixedly connected with a threaded head 10. A receiving pin 11 is threadedly connected to the lower side of the pin rod 9 through the threaded head 10 of the pin rod 9. The entire pulverizer cutter is helically locked and fixed through the threaded head 10 of the pin rod 9 and the receiving pin 11 to ensure the stability of the cutter installation. A protective disc 13 is connected to the outer side of the lower end of the fixing pin 5. A gasket 12 is provided between the lower end of the protective disc 13 and the upper end of the receiving pin 11. One end of the fixing pin 5 penetrates and is connected with a relatively large protective disc 13 for receiving. On the one hand, during the operation of the entire pulverizer, the protective disc 13 is used to block the pulverized material, preventing the material from being mixed into the transmission parts or joints and causing interference. On the other hand, the setting of the protective disc 13 can also provide isolation protection when the user disassembles the fixing pin 5, avoiding situations such as the threaded fixing pin 5 slipping when reverse spiraling, which may cause the staff to directly contact the cutting part 4 of the blade 3, thus achieving the effect of safety protection.

[0024] In summary, as Figures 1 to 3 shown, for the tool changing mechanism of this high-efficiency pulverizer, during use, first, the pulverizer cutters are arranged in a stepped manner by multiple cutter heads in a ring-shaped spiral. During the operation of the entire pulverizer, the spiral distribution of the cutters is used to comprehensively pulverize the material to be pulverized, improving the pulverization effect. When the entire pulverizer has completed its operation and the cutting part 4 of the cutter is damaged due to long-term pulverization work, by rotating the fixing pin 5, the threaded head 10 of the bottom pin rod 9 is spirally unscrewed from the receiving pin 11 to open the cutter head. At this time, the protective disc 13 provided at the end of the fixing pin 5 can provide isolation protection when the user disassembles the fixing pin 5, avoiding situations such as the threaded fixing pin 5 slipping when reverse spiraling, which may cause the staff to directly contact the cutting part 4 of the blade 3, thus achieving the effect of safety protection; then, each cutter head is removed, which is easy to disassemble, replace or maintain a single worn cutter head. The blade 3 installed at the outer end of the cutter head is also locked and fixed to the cutter head by screwing bolts. When a single one is worn, a single blade 3 can also be removed, thus avoiding the replacement of the entire cutter and ensuring the overall practicality. In this way, the use process of the tool changing mechanism of the entire high-efficiency pulverizer is completed.

[0025] The embodiments of the present invention are given for purposes of illustration and description, and are not exhaustive or limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thus design various embodiments with various modifications suitable for specific purposes.
