Detailed ways

A crusher of the present invention will be described in further detail below in conjunction with Fig. 1 to Fig. 9 of the accompanying drawings.

A kind of crusher of the present invention, please refer to Fig. 1 to Fig. 9, comprise frame 18, the box body that is fixed on frame 18, the crushing device that is installed in described box body, the material that is arranged on described box body The bin 9 and the driving device for driving the crushing device arranged above the frame 18, the crushing device includes at least one set of combined cutters 8, and the combined cutters 8 include at least two groups of rotary cutters and at least two groups of fixed cutters , the rotary cutter is detachably fixed on the main shaft 1, the fixed cutter is detachably fixed in the crusher box, the fixed cutter and the rotary cutter are arranged alternately, and the adjacent rotary cutters are arranged alternately. When in use, pour the domestic garbage that needs to be broken into the crushing device of the crusher through the hopper 9. The rotation of the main shaft 1 drives the rotary cutter to rotate, and the fixed cutter does not move. It is also staggered, so that domestic waste is squeezed, sheared and impacted between the rotary cutter and the spindle 1, between the fixed cutter and the spindle 1, and simultaneously between the fixed cutter and the rotary cutter. Therefore, compared with the prior art, it has the advantages of good crushing effect and high crushing efficiency for all kinds of household garbage, and because the fixed cutter and the rotary cutter are detachable, and are respectively fixed in the box body and the main shaft 1 Therefore, if the group of rotary cutters or fixed cutters is damaged, it can be directly disassembled for replacement without replacing the whole group of combined cutters 8, the cost of repair and maintenance is reduced, and the overall cost of crushing is reduced. A further preferred technical solution is that the staggered angle between adjacent rotary knives is 45°-75°, so that it can be ensured that the domestic waste will not be squeezed, sheared, and hit at the same time, and all the knives will bear huge pressure at the same time. The force will aggravate the damage of the blade and shorten the service life, which will affect the crushing efficiency. A more preferred stagger angle is 60°. Because the notch in the rotary tool holder 2 matches the profile of the main shaft 1, they are all regular hexagons, i.e. 60° angle, and are convenient for processing and installation. Install each group of rotary tools along the direction of the main shaft 1 with a staggered angle of 60°, so that the angle between each blade of each group of rotary tools is 15°, and there are 8 helical lines along the direction of the main shaft 1.

A kind of crusher of the present invention, please refer to Fig. 1 to Fig. 9, above-mentioned technical scheme can also be to comprise at least two groups of combined knives 8, the fixed knives of described adjacent combined knives 8 are staggered, and described adjacent combined knives 8 The rotary tools of the combined tool 8 are arranged in a staggered manner, and the position of the fixed tool of the combined tool 8 corresponds to the position of the rotary tool of another adjacent combined tool 8 . In this way, multiple groups of combined cutters 8 squeeze, shear and impact domestic waste staggered, especially the shearing, squeezing and impact between two groups of relative combined cutters 8, although the number of cutters of the overall crusher is improved. , the cost has increased, but the crushing efficiency is two to three times that of a single set of combined cutters 8, and the amount of crushed garbage is larger and faster. Moreover, the main shafts of the adjacent two groups of combination cutters 8 rotate in opposite directions, and the rotating speeds can be different, and the impact, shearing and impacting strengths are different, so as to obtain different crushing effects.

A kind of crusher of the present invention, please refer to Fig. 1 to Fig. 9, on the basis of the above-mentioned technical solution, it is also possible that the rotary cutter includes a rotary cutter seat 2 fixed on the main shaft 1 and a detachably fixed At least two rotary knife heads 3 on the circumference of the rotary knife seat 2, the fixed knife includes a fixed knife seat 4 detachably fixed in the crusher box and a fixed knife head 5 fixed on the fixed knife seat 4 , the front end of the fixed cutter head 5 is close to the outer circumference of the main shaft 1 . In this way, the rotary cutter head 3 and the fixed cutter head 5 can be disassembled, damaged and replaced separately, thereby reducing maintenance costs and improving the service life of the overall cutter. Moreover, when the rotary cutter rotates with the main shaft 1, it drives the rotary cutter head 3 to rotate, hits domestic waste, and works together with the fixed cutter head 5 to cut and cut the domestic waste near the main shaft 1, ensuring that all kinds of domestic waste are crushed completely. A further preferred technical solution is to arrange the rotary tool heads 3 symmetrically along the circumference of the rotary tool seat 2 . The advantage of the symmetrical setting is that the striking force and the shearing force are uniform, which will not cause the vibration of the main shaft 1 at a large angle, and reduce the phenomenon of stress concentration. A further preferred technical solution is to arrange eight rotary cutter heads 3 along the circumference of the rotary tool holder 2 , and the rotary cutter heads 3 are arranged in a spiral relative to the main shaft 1 . In this way, the eight rotary cutter heads 3 can fully hit, impact and cut domestic garbage and various kinds of garbage wound on the other side's main shaft 1 during the rotation process, so that the crushing is more complete and more uniform. It is also possible that the middle part of the rotary cutter head 3 is provided with a raised cutting edge, and all the cutting edges on the one rotary cutter seat 2 are located on an arc surface. In this way, it can be ensured that the distance between it and the main shaft 1 of the box body or another group of combined cutters 8 is even, and larger unbroken household garbage will not be missed, and the block comparison of the broken household garbage can be controlled. uniform and small enough.

A kind of crusher of the present invention, please refer to Fig. 1 to Fig. 9, on the basis of the above technical solution, the outer wall section shape of the main shaft 1 can also be polygonal, and the center of the rotary knife seat 2 is provided with a polygonal gap. The gap corresponds to the cross-sectional size and shape of the outer wall of the main shaft 1 . The advantage of the correspondence between the gap and the shape and size of the outer wall section of the main shaft is that the rotary knife holder 2 can be detachably fixed on the main shaft 1 and rotate with the main shaft 1 to drive the rotary knife head 3 to rotate, hit, cut and impact domestic garbage, and disassemble It is convenient and convenient to replace the damaged rotary knife holder 2 and the rotary knife head 3 . It can also be that the cross-sectional shape of the outer wall of the rotary knife seat 2 is polygonal, and the polygonal shape of the cross-sectional shape of the outer wall of the rotary knife seat 2 corresponds to the size and shape of the rotary cutter head 3, so that it is convenient to install the rotary cutter head 3 . A further preferred technical solution is that the cross-sectional shapes of the notch and the outer wall of the main shaft 1 are regular hexagons. In this way, forming is easier and the cost is lower.

A kind of crusher of the present invention, please refer to Fig. 1 to Fig. 9, on the basis of the above-mentioned technical solution, it can also be that the fixed knife seat 4 is in the shape of an arc near the main shaft 1, and the fixed knife seat 4 is far away from the main shaft 1 is fixed with the box body, the fixed cutter head 5 is arranged on the top of the fixed cutter seat 4, and the blade of the fixed cutter head 5 is close to the outer wall of the main shaft 1 as a whole. The circular arc-shaped fixed knife seat 4 can cut domestic garbage into a small size through the fixed knife head 5, and can squeeze the garbage through the main shaft 1 and the circular arc shape. Moreover, the blade of the fixed cutter head 5 can cut the household garbage wound on the main shaft 1 . In addition, it is also possible that the fixed cutter head 5 and the fixed cutter holder 4 are fixed by bolts 6, the fixed cutter holder 4 and the box body are fixed by bolts 6, and the rotary cutter head 3 and the rotary cutter holder 2 Fasten with bolt 6. This fixation is more firm, and easy to disassemble.
