DETAILED DESCRIPTION

[0022] Please refer to Figures 1-3 , the utility model discloses a kind of fodder raw material grinder's rotor, including support roller 1, the front and rear ends of support roller 1 are all fixed with support shaft 2, and the outside of support roller 1 is uniformly fixed with multiple support discs 3 from front to back, the upper and lower sides of the front surface of support disc 3 are all installed with fodder grinder blade 4, two fodder grinder blades 4 mutually adhere, the front surface of fodder grinder blade 4 is movably penetrated and connected with multiple support bolts 5, the rear end of support bolt 5 is screw-connected in the inside of support disc 3;

[0023] Support shaft 2 is connected to driving equipment, such as motor;

[0024] Support bolt 5 is screwed by clockwise rotation;

[0025] The upper and lower two fodder grinder blades 4 form a complete fodder grinder blade, when part is damaged, the damaged part can be replaced, without replacing the entire fodder grinder blade.

[0026] In Figures 1-4 , the outside of support bolt 5 is fixed with ratchet 6, the upper end of ratchet 6 is adhered with pawl 7, the left end inside of pawl 7 is rotatably connected with rotating shaft 8, and the upper surface of pawl 7 is fixed with first spring 9 at the position close to rotating shaft 8, the upper end of first spring 9 is fixed with fixed block 10, and the rear end of rotating shaft 8 and fixed block 10 are both fixed on the front surface of fodder grinder blade 4;

[0027] Ratchet 6 is welded on the outside of support bolt 5, and rotating shaft 8 and fixed block 10 are both welded on the front surface of fodder grinder blade 4;

[0028] Pawl 7 adheres to ratchet 6, so that ratchet 6 can rotate clockwise, cannot rotate counterclockwise, which avoids rotating of support bolt 5 when not needing to rotate counterclockwise, thereby avoiding loosening, and ensuring the firmness of fodder grinder blade 4;

[0029] Pulling pawl 7 away from ratchet 6 upwards can rotate support bolt 5 counterclockwise.

[0030] In Figures 3-5The lower surface of the fixed block 10 is provided with a positioning mechanism 11 in front of the first spring 9, the positioning mechanism 11 comprises a fixed rod 12, the upper end of the fixed rod 12 is fixedly connected to the lower surface of the fixed block 10, and the fixed rod 12 is located in front of the first spring 9, the lower end of the fixed rod 12 is movably penetrated and connected with a pull rod 13 in the front-rear direction, the rear end of the pull rod 13 is fixedly connected with a positioning block 14, and the outside of the pull rod 13 is provided with a second spring 15 between the fixed rod 12 and the positioning block 14, the front end of the second spring 15 is fixedly connected to the fixed rod 12, and the rear end of the second spring 15 is fixedly connected to the positioning block 14, the rear surface of the positioning block 14 is fixedly connected with a positioning rod 16, and the positioning rod 16 is movably embedded in the inside of the pawl 7;

[0031] The positioning rod 16 is clamped in the inside of the front surface of the pawl 7 through the elastic force of the second spring 15, so that the pawl 7 is always attached to the ratchet wheel 6, and further rotation of the support bolt 5 when not needed is avoided, and therefore the stability of the fodder pulverizer blade 4 is further ensured.

[0032] The working principle of the utility model is: when the fodder pulverizer blade 4 is installed, the fodder pulverizer blade 4 is attached to the front surface of the support disc 3, the pawl 7 is pulled upwards, the support bolt 5 is passed through the fodder pulverizer blade 4 and is screwed into the support disc 3, when the pawl 7 is opposite to the ratchet wheel 6, the pawl 7 is loosened and the support bolt 5 is continuously rotated until the support bolt 5 is screwed tightly, finally, the pull rod 13 is loosened so that the positioning rod 16 is embedded in the pawl 7; when the fodder pulverizer blade 4 needs to be replaced because of damage, the pull rod 13 is pulled forward to drive the positioning rod 16 to move away from the inside of the pawl 7, then the pawl 7 is pulled upwards to move away from the ratchet wheel 6, finally the support bolt 5 is counterclockwise rotated to be unscrewed, and then the fodder pulverizer blade 4 can be disassembled.
