The technical features of the chopping device 10 of the present invention have been described, and for the convenience of a better understanding of the technical features of the present invention and the effects that can be achieved, the operation of the chopping device 10 of the present invention will be further described below. Assuming that the extended suction assembly 39 is to be used to suck fallen leaves on the ground, in this state, the movable gate 115 will be in the closed position, so that the first space 34 is not communicated with the first collecting hopper 50 ( The outer cover 69 can close the second collecting hopper 68), and in this state, when the driving device 117 drives the fan blade cutter set 72 to rotate, the fan blade 90 of the fan blade cutter set 72 will The air in the second space 64 is extruded and ejected toward the outlet 66, so that the first space 34 generates a negative pressure (the first space 34 and the second space 64 communicate with each other). communicated through the perforation 26), further enabling the suction nozzle 42 to generate suction to suck the ground such as fallen leaves and small branches into the first space 34.

In addition, due to the centrifugal force of the rotation of the movable blades 94, the movable pieces 94 pivot until the crushing portion 98 protrudes from the outer periphery of the main blade 92 (as shown in FIG. 5 ) and is ready to strike. crush objects entering the first space 34.

After the fallen leaves or the small branches enter the first space 34, the main blade 92 and the movable blades 94 can break the fallen leaves and the small branches into fragments, and Since the airflow generated by the operation of the fan blade cutter set 72 flows from the first space 34 to the second space 64, the debris flows into the second space 64 along with the airflow, further because As the airflow is discharged from the outlet 66, the debris will also be discharged from the outlet 66 together with the airflow (the second collecting hopper 68 is closed by the outer cover 69).

Assuming that the small branches (twigs that cannot be sucked by the suction nozzle 42) are to be crushed, the outer cover 69 is opened, so that the small branches can be put into the second collecting hopper 68, which are located in the The twigs of the second collection hopper 68 will be guided into the second space 64, and further the two sub-blades 113 can crush the twigs into pieces, and because the air flow is from the The second space 64 flows toward the discharge port 66 , so debris in the second space 64 will be discharged from the discharge port 66 .

Assuming that larger branches (thicker branches of smaller branches) are to be crushed, as shown in Figure 7, the movable gate 115 is displaced to the open position, so that the second inlet 38 is opened (the The outer cover 69 can close the second collection hopper 68), so that the larger branches can be dropped into the first collection hopper 50, and further the first collection hopper 50 will guide the larger branches import the first empty In the room 34, the rotating main blade 92 and each movable blade 94 can gradually break the larger branches into fragments.

It is worth mentioning that, when the movable gate 115 is in the open position, since the first space 34 sucks in air through the first and the second inlets 38 at the same time, this will make the suction nozzle 42 place The suction is significantly weakened, so that the extended suction assembly 39 will not affect the crushing operation, reducing the risk of using the first collecting hopper 50 or the second collecting hopper 68 for crushing operations (the powerful suction of the suction nozzle 42 may suck the human body such as hair or clothing).

Through the setting of the fan blade cutter set 72, when the fan blade cutter set 72 rotates, the first space 34 can be made to generate negative pressure so that the extended suction assembly 39 can suck the branches and leaves on the ground. After being crushed into the first space 34 and discharged from the discharge port 66, the efficiency of workers picking up fallen leaves and twigs on the ground can be increased.

The connecting wall 20 is located between the main blade 92 and the fan blade 90, so that the fan blade 90 is properly spaced from the main blade 92, the fan blade 90 can run smoothly and lower the The probability that the fan blade 90 will collide with the branch and be damaged.

The extended suction assembly 39 can directly inhale lighter fallen leaves and branches on the ground, the first collection hopper 50 allows to put in larger branches, and the second collection hopper 68 can drop in small leaves and branches that cannot be extended by the extension. The twigs directly inhaled by the suction assembly 39 make the chopping device 10 of the present invention very versatile.

The main blades 92 and the movable blades 94 are staggered in three layers along the axial direction of the turntable 74 , so that the chopping such as leaves or branches is very efficient.

Having illustrated the basic teachings of this creation, many extensions and variations will be apparent to those of ordinary skill in the art. For example, the shredding device 10 may not include Including the second collecting hopper 68 and the feeding port 62, in such a state, branches that cannot be directly sucked by the extended suction assembly 39 can still be put into the first collecting hopper 50 for crushing. Alternatively, the chopping device 10 may not include the first and the second collection hoppers 50, 68, the second inlet 38 and the feed port 62, and in such a state, the chopping The device 10 still has an extended suction assembly 39 that can suck in lighter fallen leaves and branches for crushing.

Since the invention disclosed in this specification can be embodied in other specific forms without departing from the spirit or general characteristics of the invention, and some of these specific forms have been indicated, the embodiments disclosed in this specification should be regarded as illustrative and not restrictive. The scope of this creation is defined by the attached scope of patent application, rather than by the above description, and all changes that fall within the equivalent meaning and scope of the scope of patent application will still be included in its scope.
