DETAILED DESCRIPTION

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention. Example

[0027] Reference Figure 1-5 As shown, a blade block mechanism of a branch shredder of the utility model comprises:

[0028] Barrel 1 mechanism, the barrel 1 is connected to the feed barrel 2 and the discharge barrel 3;

[0029] The knife block mechanism includes: a knife disc 4 rotatably connected to the barrel 1, an upper knife block 5 arranged on the knife disc 4, a base plate 81 arranged at the entrance of the barrel 1, and a lower knife block 9 arranged on the base plate 81, wherein a cutting space is provided between the upper knife block 5 and the knife disc 4, and the lower knife block 9 can be movably arranged close to or away from the knife disc 4 and fixed by a locking assembly.

[0030] The utility model discloses a branch shredder blade mechanism, which forms a cutting space with the lower blade block 9 when the upper blade block 5 makes a circular motion, and cuts and crushes branches entering the cutting space. By adjusting the position of the lower blade block 9 on the base plate 81 and cooperating with the locking assembly to unlock, move and lock the lower blade block 9, the distance between the upper blade block 5 and the blade disc 4 can be controlled, so that the width of the cutting space between the upper blade block 5 and the blade disc 4 changes accordingly, thereby adapting to branches of different thicknesses, achieving complete cutting of small branches to avoid clogging the discharge barrel 3, or cutting of thicker branches, and accommodating and cutting off thicker branches, so that the branches can be fully chopped to improve the utilization rate.

[0031] like Figure 2 The locking assembly shown includes: a protrusion 8 arranged at the end of the base plate 81, a first hole 83 opened in the protrusion 8, and a first bolt 10 passing through the first hole 83 and locked to the first side of the lower knife block 9. By rotating the first bolt 10 forward and reversely, the first bolt 10 and the first threaded hole 93 on the first side of the lower knife block 9 are threadedly transmitted, so that the lower knife block 9 is close to or away from the knife disc 4, and the lower knife block 9 is locked by thread self-locking, so that the lower knife block 9 cannot approach or move towards the knife disc 4 by pulling or pushing.

[0032] Continue to see Figure 2 As shown, it also includes a fixing component, which is arranged on the base plate 81 and locks the second side of the lower knife block 9. Specifically, the fixing component includes: a second hole 84 opened in the base plate 81, a second bolt 11 passing through the second hole 84 and extending to the second side of the lower knife block 9, the projection of the second hole 84 on the horizontal plane extends in a direction close to or away from the barrel 1, the second hole 84 is a strip hole with a length, and the width is adapted to the second bolt 11, so that the second bolt 11 can move along the length direction of the second hole 84 to adapt to the position of the lower knife block 9 close to or away from the knife disc 4, and is threadedly locked with the second threaded hole 94 on the second side of the lower knife block 9, further fixing the lower knife block 9, and providing tension in a direction perpendicular to the base plate 81. In this embodiment, the protrusion 8 is perpendicular to the base plate 81, and the axial directions of the first bolt 10 and the second bolt 11 are also perpendicular to each other, so that the first bolt 10 and the second bolt 11 can provide tension in two vertical directions, and bear the corresponding supporting forces in the two vertical directions through the base plate 81 and the protrusion 8, thereby forming a stable lock on the lower knife block 9.

[0033] See also Figure 1 As shown, there is a storage space 6 between the knife disc 4 and the wall of the barrel 1. The branches pass through the cutting area and enter the storage space 6 in the barrel 1. They are driven by the rapidly rotating upper knife block 5 in the storage space 6 to be thrown out from the discharge tube 3. In the storage space 6, the branches can be in a stacked state, so that the upper cutter can further cut the branches when it rotates to the storage space 6. The bottom of the storage space 6 is circular. When the upper cutter rotates and presses the branches in the storage space 6, the branches are prevented from being pressed tightly to cause the knife to get stuck, and the resistance is reduced to facilitate the branches to be taken out of the storage space 6.

[0034] See also Figure 1As shown, the substrate 81 is arranged at the bottom of the connection between the feed barrel 2 and the material barrel 1, the substrate 81 is inclined, and the inclination angle of the substrate 81 is equal to that of the feed barrel 2, the substrate 81 is welded to the material barrel 1, and the discharge barrel 3 and the feed barrel 2 are also welded on both sides of the material barrel 1. The inclined substrate 81 transitions between the material barrel 1 and the feed barrel 2, and it is inclined to the side away from the knife disc 4, and the angle with the horizontal plane is 30°-60°. In this embodiment, the angle is 38°, and the substrate 81 and the protrusion 8 constitute a fixed plate 8.

[0035] See also Figure 5 As shown, the shaft hole of the barrel 1 is equipped with a main shaft 7, and the end fixed sleeve of the main shaft 7 is provided with a pulley 12. The main shaft 7 is driven to rotate by the belt and the driving pulley 12, and the main shaft 7 drives the cutter disc 4 and the upper cutter block 5 to rotate.

[0036] See also Figure 3 As shown, the lower blade block 9 includes a base portion 91 and a protrusion 92, the base portion 91 is attached to the substrate 81, both sides of the protrusion 92 are inclined surfaces, and the second inclined surface 922 of the protrusion 92 on the side close to the blade 4 is a vertical surface, and the first inclined surface 921 on the other side of the protrusion 92 is a horizontal surface, the second inclined surface 922 and the adjacent base portion 91 constitute one side of the cutting space, the junction of the first inclined surface 921 and the second inclined surface 922, and the junction of the second inclined surface 922 and the base portion 91 constitute a blade, and the branches are cut by the blade.

[0037] The upper blade block 5 and the lower blade block 9 are arranged correspondingly and have the same length. When the upper blade block 5 rotates to the cutting space, the blade portion is close to the side of the lower blade block 9 and is parallel to the second inclined surface 922. The upper blade block 5 and the lower blade block 9 are arranged correspondingly and have the same length. The mechanism can maintain balance during operation, reduce vibration and instability, thereby improving the overall stability, making the cutting pressure between the upper and lower blade blocks 9 evenly distributed during the cutting process, preventing different parts of the wood from being subjected to excessive pressure, and ensuring the consistency and quality of the cutting.

[0038] The method of using the knife block mechanism of this embodiment is as follows: 1. Use laser cutting to cut the shape of the lower knife block 9 fixing plate 8, tap two M8.0 screw holes, and then use sheet metal bending to make the lower knife block 9 fixing plate 8; 2. The upper cutter is made of high-speed steel material and machined to the finished product; 3. Weld the sheet metal structure of the barrel 1; 4. Connect the knife block fixing plate 8 and the sheet metal structure of the barrel 1 by welding; 5. Lock the upper knife block 5 on the knife disc 4 with M12*25MM screws, rotate the knife disc 4 to check that the upper knife block 5 is fixed intact and there is no abnormal interference. 6. Connect the lower knife block 9 that has been made with M10*25MM screws first, and use M8*40 screws to connect it with the lower knife block 9 from the screw holes of the fixing block plate, adjust the gap accordingly according to the gap requirements, and tighten the fixing screws of the lower knife block 9 after adjustment, and it can be used normally.
