Description

Technical Field

[0001] The invention relates to a crushing cutter disc and belongs to the technical field of food waste crushers. Background Art

[0002] The food waste in the catering industry is generally treated as ordinary garbage and collected and processed by the sanitation department. The disadvantages of this treatment method are that it is large in size, contains moisture, is easy to deteriorate, and will cause environmental pollution. Therefore, now the food waste is generally crushed and dehydrated with a food waste crusher before being collected and processed by the sanitation department. The advantage of using a food waste crusher is that after crushing and dehydration, the volume of the food waste is greatly reduced, which is convenient for the sanitation department to collect and process, and the food waste is not easy to deteriorate after dehydration, and will not cause environmental pollution. At present, the cutter disc of the food waste crusher is connected to the drive device (motor) through a coupling. During the rotation and crushing, the residue will accumulate on the outside, and the crushing efficiency is not high; and the screw head between the fixed cutter disc and the coupling will be exposed to the outside. When encountering hard objects during the crushing process, it is easy to cause damage to the screw head, which is inconvenient to disassemble. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a crushing cutter disc, which solves the problems that the crushing efficiency of the cutter disc of the current food waste crusher needs to be improved and the fixing structure with the coupling is unreasonable.

[0004] The technical problem to be solved by the present invention is achieved by adopting the following technical solutions:

[0005] A crushing cutter disc, comprising a coupling, a large cutter disc, a center disc, fixing screws, locking screws, a trapezoidal scraper and a crushing cutter head. The coupling, large cutter disc and center disc are coaxially arranged in sequence from bottom to top. The middle part of the large cutter disc is fixed above the coupling by a plurality of fixing screws. The center disc covers the fixing screws of the large cutter disc. The middle part of the center disc is fixed to the coupling by a locking screw. The locking direction of the locking screw is opposite to the rotation direction of the coupling. A plurality of trapezoidal scrapers are fixed to the circumferential edge of the large cutter disc. The inclined surfaces of the trapezoidal scrapers face the rotation direction of the large cutter disc. A plurality of crushing cutter heads are evenly distributed on the surfaces of the large cutter disc and the center disc. A plurality of crushing cutter heads are also arranged on the top and the outer side of the trapezoidal scraper. The blades of the crushing cutter heads all face the rotation direction of the large cutter disc.

[0006] As a preferred example, a blind hole for accommodating the head of a fixing screw is provided on the lower surface of the center disk, and the inner diameter of the blind hole is equal to the outer diameter of the head of the fixing screw.

[0007] As a preferred example, the cutting edge of the crushing cutter head is an inclined right-angled prism-shaped cutting edge.

[0008] As a preferred example, the large blade disc and the center disc are made of stainless steel.

[0009] As a preferred example, the bottom of the trapezoidal scraper is provided with a plurality of threaded holes and matching scraper fixing screws. The scraper fixing screws pass through the large blade disc from below and are inserted into the threaded holes to fix the large blade disc and the trapezoidal scraper.

[0010] The arrangement of the coupling, large cutter disc, center disc, fixing screws, locking screws, trapezoidal scraper blade and crushing cutter head enables the cutter disc to achieve dynamic balance as a whole.

[0011] The beneficial effects of the present invention are as follows: the center disk covers the fixing screws of the large blade disk, which can prevent the fixing screws from being damaged by hard objects; the middle part of the center disk is fixed to the coupling by a locking screw, the linear speed of the middle part is relatively small, and hard objects will not damage the locking screws; the locking direction of the locking screws is opposite to the rotation direction of the coupling, and after the coupling rotates, the locking screws can be prevented from loosening; the trapezoidal scraper arranged on the circumferential edge can shovel up the deposits and scatter them to the inside and outside, contact with more crushing heads, and improve the crushing efficiency; the blade of the crushing head adopts an inclined right-angle prism blade, which is sturdy and durable.

[0016] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0017] like Figure 1-Figure 3As shown, a crushing cutter disc comprises a coupling 1, a large cutter disc 2, a center disc 3, fixing screws 4, locking screws 5, a trapezoidal scraper 6, and a crushing cutter head 7. The coupling 1, the large cutter disc 2, and the center disc 3 are coaxially arranged in sequence from bottom to top. The middle part of the large cutter disc 2 is fixed above the coupling 1 by multiple fixing screws 4. The center disc 3 covers the fixing screws 4 of the large cutter disc 2. The middle part of the center disc 3 is fixed to the coupling 1 by the locking screws 5. The locking direction of the locking screws 5 is opposite to the rotation direction of the coupling 1. A plurality of trapezoidal scrapers 6 are fixed to the circumferential edge of the large cutter disc 2. The inclined surface of the trapezoidal scraper 6 faces the rotation direction of the large cutter disc 2. A plurality of crushing cutter heads 7 are evenly distributed on the surface of the large cutter disc 2 and the center disc 3. A plurality of crushing cutter heads 7 are also arranged on the top and the outside of the trapezoidal scraper 6. The blades of the crushing cutter heads 7 all face the rotation direction of the large cutter disc 2.

[0018] A blind hole (not shown) for accommodating the head of the fixing screw is provided on the lower surface of the center disk 3 , and the inner diameter of the blind hole is equal to the outer diameter of the head of the fixing screw 4 .

[0019] The cutting edge of the crushing cutter head 7 is an inclined right-angled prism-shaped cutting edge 71, and the crushing cutter head 7 is made of hard alloy. The right-angled prism-shaped cutting edge 71 of the crushing cutter head 7 is along the tangent direction of the circumference of the crushing cutter head 7.

[0020] The large knife disc 2 and the center disc 3 are made of stainless steel.

[0021] The bottom of the trapezoidal scraper 6 is provided with a plurality of threaded holes and a matching scraper fixing screw 8. The scraper fixing screw 8 passes through the large blade disc 2 from below and is inserted into the threaded hole to fix the large blade disc 2 and the trapezoidal scraper 6.

[0022] The positions of the coupling 1, the large cutter disc 2, the center disc 3, the fixing screw 4, the locking screw 5, the trapezoidal scraper 6, and the crushing cutter head 7 are arranged so that the cutter disc as a whole achieves dynamic balance. The crushing cutter head 7 is fixed to the large cutter disc 2, the center disc 3, and the trapezoidal scraper 6 by welding.

[0023] Working principle: the center disk 3 covers the fixing screws 4 of the large blade disk 2 to prevent the fixing screws 4 from being damaged by hard objects. The middle part of the center disk 3 is fixed to the coupling 1 by the locking screws 5. The linear speed of the middle part is relatively small, and hard objects will not damage the locking screws 5. The locking direction of the locking screws 5 is opposite to the rotation direction of the coupling 1. After the coupling 1 rotates, the locking screws 5 can be prevented from loosening; the trapezoidal scraper 6 arranged on the circumferential edge can shovel up the deposits and scatter them to the inside and outside, contacting with more crushing heads 7 to improve the crushing efficiency; the blade of the crushing head 7 adopts an inclined right-angle prism blade 71, which is sturdy and durable.
