DETAILED DESCRIPTION

[0021] Please refer to Figures 1-2 An adjustable cutter group of pulverizer, including cutter shaft 1 and cutter roll 2, cutter roll 2 is fixedly installed on cutter shaft 1 through shaft sleeve 21 and bolt, cutter shaft 1 is equipped with flat key 11, and cutter roll 2 and the inner wall of shaft sleeve 21 are all provided with keyway 22 connected with flat key 11.

[0022] The engagement of the flat key 11 and the key groove 22 can ensure the consistency of the angle between the cutter roller 2 and the cutter shaft 1. Due to the positioning effect of the flat key 11, the cutter roller 2 can rotate accurately according to the rotating direction and angle of the cutter shaft 1, effectively preventing the circumferential sliding of the cutter roller 2 relative to the cutter shaft 1, and forming a closely integrated whole structure between the cutter shaft 1 and the cutter roller 2, which can better resist deformation and ensure the stability of the cutter blade 3 during the crushing of the material.

[0023] To solve the technical problem of how to adjust the length of the cutter head of the cutter group of the crusher, please refer to Figures 3-5 The embodiment provides the following technical scheme:

[0024] The side end of the cutter roller 2 is provided with a ring-shaped array of cutter grooves 25, the cutter grooves 25 are inserted with cutter blades 3, the cutter blades 3 are provided with adjustable holes 31 for adjusting the length of the cutter head, and the cutter grooves 25 located at one end outside the cutter roller 2 are provided with limiting plates 26 for clamping the cutter blades 3.

[0025] The front and rear ends of the cutter roller 2 are detachably provided with end plates 23, the front and rear ends of the cutter roller 2 are provided with positioning screws 24, the end plates 23 are inserted into the positioning screws 24 through fixing holes 233, and one end of the positioning screw 24 outside the fixing hole 233 is fastened by a nut.

[0026] The end plate 23 is welded with a ring-shaped array of positioning grooves 231 which are in clamping connection with the limiting plates 26, the positioning grooves 231 are provided with positioning holes 232 which are matched with the adjustable holes 31, and the positioning holes 232 and the adjustable holes 31 are jointly inserted with fixing rods 27, and one end of the fixing rod 27 outside the positioning hole 232 is fastened by a nut.

[0027] The cutter grooves 25 are provided with sliding grooves 251 on the left and right sides, the cutter blades 3 are welded with protrusions 32 which are in sliding connection with the sliding grooves 251, and when the protrusions 32 are located at the top and bottom positions inside the sliding grooves 251, the adjustable holes 31 are aligned with the positioning holes 232.

[0028] In the process of inserting the cutter blade 3 into the cutter groove 25, the limiting plate 26 plays a role in horizontal positioning, limiting the horizontal movement of the cutter blade 3 in the cutter groove 25, ensuring that the cutter blade 3 can be accurately located at the predetermined position in the cutter groove 25, and when the cutter roller 2 rotates at high speed, the cutter blade 3 will be subjected to centrifugal force and reaction force of the material, etc., and the limiting plate 26 can effectively clamp the cutter blade 3 to prevent the cutter blade 3 from being pulled out of the cutter groove 25;

[0029] The clamping connection of the positioning groove 231 and the limiting plate 26 can effectively position the end plate 23 and the cutter roller 2 at the end, enhancing the positioning of the cutter blade 3, so as to ensure that the adjustable hole 31 can be aligned with the positioning hole 232, and the length of the cutter head can be accurately adjusted;

[0030] The sliding groove 251 provides accurate guidance for the movement of the blade 3, and the position of the protrusion 32 on the blade 3 is designed to cooperate with the sliding groove 251 to achieve positioning of the blade 3. When the protrusion 32 is at the bottom end of the sliding groove 251, the adjusting hole 31 at the upper end is aligned with the positioning hole 232, and at this time the length of the cutter head is short. When the protrusion 32 is at the top end of the sliding groove 251, the adjusting hole 31 at the lower end is aligned with the positioning hole 232, and at this time the length of the cutter head is long.

[0031] Specifically, the nut outside the positioning hole 232 of the fixing rod 27 is unscrewed using a wrench, and the fixing rod 27 is removed from the cutter roll 2. At this time, the blade 3 is no longer restricted by the fixing rod 27, and the length of the cutter head of the blade 3 can be adjusted as needed. The blade 3 is manually pushed so that the protrusion 32 slides in the sliding groove 251 until the protrusion 32 is at the top end or the bottom end of the sliding groove 251. At this time, the adjusting hole 31 is aligned with the positioning hole 232 on the end plate 23. Then the fixing rod 27 is reinserted into the positioning hole 232 and the adjusting hole 31, and finally the two ends are locked with nuts.

[0032] Working principle: When the length of the cutter head needs to be adjusted, the nut outside the positioning hole 232 of the fixing rod 27 is unscrewed using a wrench, and the fixing rod 27 is removed from the cutter roll 2. At this time, the blade 3 is no longer restricted by the fixing rod 27, and the length of the cutter head of the blade 3 can be adjusted as needed. The blade 3 is manually pushed so that the protrusion 32 slides in the sliding groove 251 until the protrusion 32 is at the top end or the bottom end of the sliding groove 251. At this time, the adjusting hole 31 is aligned with the positioning hole 232 on the end plate 23. Then the fixing rod 27 is reinserted into the positioning hole 232 and the adjusting hole 31, and finally the two ends are locked with nuts.

[0033] When the blade 3 needs to be replaced, the nut outside the positioning hole 232 of the fixing rod 27 and the nut outside the fixing hole 233 of the positioning screw 24 are unscrewed using a wrench, and then one of the end plates 23 is disassembled. At this time, the blade 3 in the cutter slot 25 can be pulled out, and a new blade 3 is reinserted into the cutter slot 25 and the length of the cutter head is adjusted. The fixing rod 27 is inserted into the adjusting hole 31 and the positioning hole 232, and the nut is used to fix the end of the fixing rod 27 connected to the end plate 23 that has not been disassembled. Then the disassembled end plate 23 is reattached to the end of the cutter roll 2, and the nut is used to fix the positioning screw 24 and the end of the fixing rod 27 outside the end plate 23.
