[0023] The following is a detailed description of the present invention, clearly and completely describing the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] The utility model provides a branch chipper cutting roller with a forced feeding function through improvement. The technical solution of the utility model is:

[0025] Example 1:

[0026] like Figure 1-Figure 2 As shown, a branch chipper cutting roller with a forced feeding function includes two mounting plates 1, a rotating shaft 2 is rotatably connected between the two mounting plates 1, a rotating sleeve 3 is slidingly sleeved on the outer side of the rotating shaft 2, and further includes: a cutting assembly and a reciprocating mechanism, the cutting assembly is arranged on the outer side of the rotating sleeve 3; the reciprocating mechanism is arranged at both ends of the rotating shaft 2; the cutting assembly includes a plurality of side plates 4 fixed to the outer side of the rotating sleeve 3 at equal intervals, two flinger shafts 5 are symmetrically fixed through the inner sides of the plurality of side plates 4, and a plurality of circumferentially distributed knife seats 6 are fixed on the outer sides of the plurality of side plates 4 at equal intervals, blades 7 are fixed on the upper sides of the plurality of knife seats 6 at equal intervals by a plurality of screws 61, and a plurality of groups of flinger bodies 8 are fixed on the outer sides of the two flinger shafts 5 at equal intervals;

[0027] Combined with the description of the above-mentioned cutting assembly, when the wood is crushed, the rotating shaft 2 is driven to rotate by an external driving mechanism, and the rotation of the rotating shaft 2 drives the rotating sleeve 3 arranged on the outside thereof to rotate synchronously, and the rotation of the rotating sleeve 3 drives the multiple side plates 4 to rotate, and finally the multiple blades 7 and the swing knife body 8 rotate. The multiple blades 7 can perform preliminary crushing of the wood. After the preliminary crushing, the wood falls due to gravity and is further crushed by the multiple swing knife bodies 8, thereby improving the crushing effect and ensuring that the crushing of the wood meets the particle size requirements.

[0028] like Figure 1 Figure 2 As shown, in one embodiment, the plurality of blades 7 are all made of hard alloy material, which has extremely high hardness and wear resistance, thereby ensuring a good cutting effect on wood.

[0029] Example 2:

[0030] like Figure 3-Figure 4 As shown, in the second embodiment, the reciprocating mechanism includes a spherical rod 9 fixed to one side of one mounting plate 1, an abutment block 10 fixed to one end of the rotating sleeve 3, and a fixed disk 11 rotatably connected to the other end of the rotating sleeve 3. A connecting rod 12 is fixed to the outside of the fixed disk 11, and the connecting rod 12 is fixed to one side of the other mounting plate 1. A spring 13 is sleeved on the outside of the rotating shaft 2 at one end. One end of the spring 13 is fixed to one side of the other mounting plate 1, and the other end of the spring 13 is fixed to one side of the fixed disk 11. The spherical rod 9 abuts against one side of the abutment block 10.

[0031] Combined with the description of the above-mentioned reciprocating mechanism, the rotating sleeve 3 rotates and drives the abutment block 10 fixed at one end thereof to rotate synchronously, and the spherical rod 9 and the abutment block 10 abut, so that the inclined surface on one side of the abutment block 10 rotates along the side of the spherical rod 9. When the raised end of the abutment block 10 rotates to the side of the spherical rod 9, the spherical rod 9 squeezes the abutment block 10, driving the abutment block 10 and the rotating sleeve 3 to move along the outside of the rotating shaft 2, and at the same time squeezing the spring 13. When the raised end of the abutment block 10 separates from the spherical rod 9, the elastic potential energy of the spring 13 resets the abutment block 10 and the rotating sleeve 3, and finally drives the cutting assembly to reciprocate, further increasing the contact surface between the cutting assembly and the wood, and improving the cutting effect on the wood.

[0032] like Figure 4 As shown, in the second embodiment, in order to ensure that the rotating sleeve 3 can rotate synchronously with the rotating shaft 2 without affecting the subsequent reciprocating movement, a rib 14 is fixed on the outer side of the rotating shaft 2, and a groove 15 adapted to the rib 14 is provided on the inner side of the rotating sleeve 3.

[0033] like Figure 1 As shown, in the second embodiment, mounting holes 16 are provided at the four inner corners of the two mounting plates 1. The multiple mounting holes 16 facilitate the installation of the two mounting plates 1 on the main structure, thereby ensuring the overall installation effect of the cutting assembly and the reciprocating mechanism. At the same time, when a fault occurs, it can be disassembled for easy maintenance and regular cleaning.

[0034] like Figure 1 As shown, in the second embodiment, one end of the rotating shaft 2 is fixedly connected to the output end of the driving device through a connecting shaft.

[0035] The specific working method is: when in use, the rotating shaft 2 is driven to rotate by an external driving mechanism, and the rotation of the rotating shaft 2 drives the rotating sleeve 3 sleeved on the outside thereof to rotate synchronously. A convex rib 14 is fixed on the outside of the rotating shaft 2, and a groove 15 adapted to the convex rib 14 is provided on the inside of the rotating sleeve 3, ensuring that the rotating sleeve 3 can rotate synchronously with the rotation of the rotating shaft 2 without affecting the subsequent reciprocating movement. The rotation of the rotating sleeve 3 drives the rotation of multiple side plates 4, and finally the multiple blades 7 and the flinger body 8 rotate. The multiple blades 7 can perform preliminary crushing of the wood. The wood after preliminary crushing falls by gravity and is further crushed by the multiple flinger bodies 8, thereby improving the crushing effect and ensuring that the crushing of the wood meets the particle size requirements. At the same time, the rotating sleeve 3 rotates and drives the abutment block 10 fixed at one end thereof to rotate synchronously, and the spherical rod 9 and the abutment block 10 abut, so that the inclined surface on one side of the abutment block 10 rotates along the side of the spherical rod 9. When the raised end of the abutment block 10 rotates to the side of the spherical rod 9, the spherical rod 9 squeezes the abutment block 10, driving the abutment block 10 and the rotating sleeve 3 to move along the outside of the rotating shaft 2, and at the same time squeezing the spring 13. When the raised end of the abutment block 10 is separated from the spherical rod 9, the abutment block 10 and the rotating sleeve 3 are reset by the elastic potential energy of the spring 13. Through the above principle, the cutting assembly is driven to move back and forth, further increasing the contact surface between the cutting assembly and the wood, and improving the cutting effect on the wood.

Matters not covered in the present invention belong to the common knowledge of those skilled in the art.
