DETAILED DESCRIPTION

[0019] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0020] See also Figure 1 and Figure 2 The utility model provides a technical solution: a U-shaped tool for a crusher, including a knife seat 1 and a limiting rod 4. The interior of the knife seat 1 is provided with two groups of movable cavities and the interior of the knife seat 1 is provided with a mounting hole; the inner walls of the two groups of movable cavities on the knife seat 1 are slidably mounted with movable mounting blocks 2, and the limiting rod 4 is used to limit the movable mounting blocks 2. The number of movable mounting blocks 2 is two groups, and the front sides of the two groups of movable mounting blocks 2 are fixedly mounted with blades 3. The top of the knife seat 1 is provided with a groove, the inner bottom of the movable cavity on the knife seat 1 is provided with a threaded groove, and the movable mounting block 2 is provided with a The limit rod 4 has a hole for movement, and the limit rod 4 passes through the hole on the movable mounting block 2 and is threadedly installed with the threaded groove inside the movable cavity on the tool holder 1. The top of the limit rod 4 is fixedly installed with a transmission block 5, and the transmission block 5 is located inside the groove on the tool holder 1. The top of the tool holder 1 is provided with a hole for movement of the limit rod 4. This arrangement can limit the movable mounting block 2. In this way, when using the blade 3, the distance between the two sets of blades 3 can be adjusted according to the size of the particles after the material is crushed, thereby improving the applicability of the tool and improving the practicality of the tool.

[0021] See also Figure 3-Figure 4 A grinder, including any one of the above-mentioned U-shaped cutters of a grinder, also includes a grinder body 6, a protective box 7 and a discharge pipe 9 are fixedly installed at the bottom of the grinder body 6, a dust suction fan blade 11 is fixedly installed on one side of the protective box 7, the discharge pipe 9 is located at the top of the protective box 7, a dust suction hopper 12 is fixedly installed at the bottom of the protective box 7, a first dustproof net 10 is fixedly installed on the inner wall of the protective box 7, the first dustproof net 10 is located just below the discharge pipe 9, an opening is opened on one side of the protective box 7, the opening is located on one side of the dust suction fan blade 11, an air outlet pipe 8 is fixedly installed on one side of the protective box 7, and a suction fan 12 is fixedly installed on the inner wall of the protective box 7. The dust fan blades 11 are located inside the air outlet pipe 8, and a rotating cover 13 is threadedly installed at one end of the air outlet pipe 8. A connecting rod 14 is rotatably installed on one side of the rotating cover 13, and a second dust-proof net 15 is fixedly installed at one end of the connecting rod 14. The second dust-proof net 15 is located inside the air outlet pipe 8, and four groups of ventilation openings are opened on the air outlet pipe 8. This arrangement can filter out the tiny dust generated by the material when it is crushed and discharged, so as to avoid the first dust-proof net 10 being unable to filter the tiny dust, causing the tiny dust to float in the air, affecting the air quality, and thus improving the environmental friendliness of the device when it is used.

[0022] Working principle: When the distance between the two sets of blades 3 needs to be adjusted, use a tool such as a sleeve to rotate the transmission block 5. The rotation of the transmission block 5 drives the limit rod 4 to rotate, so that the limit rod 4 can be separated from the thread groove on the knife seat 1. After separation, the movable mounting block 2 is moved. After the movable mounting block 2 moves, the limit rod 4 is passed through the movable mounting block 2 and the thread groove on the knife seat 1 for installation. When the crushed material on the crusher body 6 is discharged, the impact force generated by the discharge of the material will cause dust to float, and the dust suction fan blades 11 are controlled to start. The dust suction fan blades 11 are started to suck in the dust , and then the dust is discharged through the air outlet pipe 8. When the dust is discharged, it can be filtered by the second dust-proof net 15. The filtered dust will remain in the inside of the air outlet pipe 8. When the air outlet pipe 8 is cleaned, the rotary cover 13 is rotated to separate the rotary cover 13 from the air outlet pipe 8, and the rotary cover 13 can be moved. The movement of the rotary cover 13 drives the connecting rotating rod 14 and the second dust-proof net 15 to move, and then the second dust-proof net 15 can be pulled out from the inside of the air outlet pipe 8. The first dust-proof net 10 can prevent materials and larger dust particles from being drawn into the inside of the dust suction fan blades 11 when the materials are unloaded.
