It can adapt to the crushing of a variety of different materials by adjusting the spacing between the blades, and is conducive to controlling the size of the final crushed particle size. It has a wider application scenario. In order to realize the structural function of the device, the device is provided herein including a crushing tank 1, and a blade mounting seat 2 is rotatably provided inside the crushing tank 1, and a plurality of first blades 3 are distributed in a circular array on the blade mounting seat 2 with the blade mounting seat 2 rotating shaft as the axis. Figure 1 As shown, the blade edge of the first blade 3 is extended along the rotation axis direction of the blade mounting seat 2. When this blade edge extension method is adopted, in order to crush the material, a plurality of second blades 4 are further provided on the inner wall of the crushing tank 1, and the blade edge of the second blade 4 is extended along the rotation axis direction of the blade mounting seat 2, wherein the blade edge of the first blade 3 and the blade edge of the second blade 4 can form a shear gap during the rotation process, and crush the large particle size material into smaller particle size material. In order to improve the scope of application of the equipment so as to facilitate the processing and crushing of different particle sizes or different materials, a second blade can be provided here. The position of the blade 4 is adjustable in the direction of the line connecting the second blade 4 and the rotating shaft of the blade mounting seat 2, that is, the second blade 4 can move in the direction close to or away from the blade mounting seat 2, so as to reduce or increase the shear gap between the first blade 3 and the second blade 4, so as to achieve the crushing work of materials with various particle sizes, and can also gradually reduce the crushed particle size by adjustment until the required particle size is reached, so its application range is wider. Regarding the rotation drive of the blade mounting seat 2, a driving device 5 for driving the blade mounting seat 2 to rotate can be further provided on the crushing tank 1. The driving device 5 can be a motor, etc. Regarding the structure of the blade mounting seat 2, its specific shape can be referred to. Figure 1 and Figure 4 As described above, the first blade 3 protrudes from the outer ring of the blade mounting seat 2, so that the blade mounting seat 2 can carry the material to the shear gap between the first blade 3 and the second blade 4 when rotating, which is more conducive to the smooth progress of the crushing action.

[0026] The embodiment of the present invention provides a blade crusher. When the extending direction of the cutting edge of the first blade 3 and the second blade 4 is in the same direction as the axis of the blade mounting seat 2, in order to improve the uniformity of crushing, the rotating axis of the blade mounting seat 2 can be set to be parallel to the horizontal plane. In order to facilitate installation and maintenance, a crushing tank 1 can be provided, including a box body 101 and a bin door 102 hingedly arranged on one side of the box body 101, wherein the bin door 102 forms a crushing chamber for crushing materials with the interior of the box body 101 when in a closed state, and the bin door 102 and the box body 101 can be locked by a bolt structure, and a sealing ring is provided between the bin door 102 and the box body 101 to ensure the sealing of the crushing chamber, thereby preventing leakage of particulate material.

[0027] The embodiment of the present invention provides a blade crusher. In order to facilitate the addition of materials to be crushed into the interior of the equipment, a feed pipe 6 can be provided above the crushing tank 1, and a plug plate 8 is slidably inserted on one side of the feed pipe 6. When feeding is not required, the plug plate 8 can be directly used to block the feed opening of the feed pipe 6. In addition, by providing the plug plate 8, the size of the feed opening of the feed pipe 6 can be adjusted by sliding, thereby adjusting the speed of supplying the materials to be crushed into the interior of the equipment.

[0028] The present invention provides a blade crusher. In order to facilitate the discharge of crushed materials, a discharge port 7 can be provided below the crushing tank 1, and a receiving tank 9 is provided at the bottom end of the discharge port 7. A filter screen 10 is provided in the crushing chamber of the crushing tank 1 and at the discharge position of the discharge port 7, so that the materials meeting the filter particle size after crushing can pass through the filter screen 10 and fall into the receiving tank 9. That is, the crushing equipment can continuously supply materials to be crushed and can continuously discharge materials without stopping the machine, and can operate continuously without opening the cover, which greatly improves the production efficiency of the crusher (the materials to be crushed can be prepared in the feed pipe 6 and wait for replenishment).

[0029] A blade crusher provided by an embodiment of the present invention can be provided with a clamping groove 11 in the crushing chamber of the crushing tank 1 in order to facilitate the regulation of the size of the final discharge particle size according to processing requirements, wherein the clamping groove 11 is located above the discharge port 7, and a filter screen 10 is provided that can be clamped in the clamping groove 11. At this time, the filter screen 10 can be provided with a variety of filtering specifications, and the size of the final discharge particle size can be adjusted by changing the gap of the filter screen 10, which is conducive to meeting a variety of different production needs.

[0030] In the blade crusher provided in the embodiment of the present invention, a pushing mechanism can be provided in the feed pipe 6 to prevent the material to be crushed from being blocked in the feed pipe 6. The pushing mechanism is used to squeeze the material in the feed pipe 6 from the feed opening into the crushing tank 1. As a preferred embodiment, the pushing mechanism can include a material discharge push rod 12 and a pressure plate 13 provided at the end of the material discharge push rod 12.

[0031] The embodiment of the present invention provides a blade crusher, in which a threaded opening is provided on the top of a material receiving tank 9, and the material receiving tank 9 can be connected to the discharge position of the discharge port 7 by a threaded connection to realize the integrated collection of materials. It can be understood that the material receiving tank 9 can also be connected to the discharge port 7 by other means of connection through fixing parts, and the specific operation method is no longer limited here.

[0032] The embodiment of the present invention provides a blade crusher, which specifically provides an adjustment means for adjusting the shear gap between the first blade 3 and the second blade 4, wherein the second blade 4 is slidingly arranged inside the crushing tank 1, and the sliding direction of the second blade 4 satisfies that the sliding direction of the blade edge of the second blade 4 always points to the axis of the blade mounting seat 2, and a depth adjustment bolt for adjusting the position of the second blade 4 is also provided on the crushing tank 1, so that the depth adjustment bolt can act on the second blade 4 to realize its position offset in the sliding direction.

[0033] The present invention provides a blade crusher. In order to prevent the second blade 4 from being over-adjusted, a perspective window for displaying the adjustment depth of the second blade 4 can be provided on the crushing tank 1. As a preferred embodiment, a display scale can be provided on the perspective window. At this time, the blade head of the second blade 4 can be used as a pointer. When the position depth of the second blade 4 is adjusted by the depth adjustment bolt, it is sufficient to observe that the scale position is within a safe range. When the crushing gap needs to be adjusted according to material requirements, it is also more conducive to judging whether the current position meets the processing requirements, which is conducive to more precise adjustment.

[0034] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
