Abstract

The present invention relates to a crusher-cutter having flywheels and a cutter blade unit formed into a unitary body, wherein both ends of the cutter blade unit are fixed and coupled to the pair of flywheels to improve firmness, cutting force, and durability, and to reduce vibrations and noise. The crusher according to the present invention is equipped with said crusher-cutter. The crusher moves, and the crusher-cutter and an inlet roller are driven by the power transmitted by an engine or a hydraulic power system. The inlet roller has protruded blades which are radially formed at the outer surface of a roller drum, and inclined toward the outer surface of the roller drum. Each of the protruded blades has cutout grooves formed at predetermined intervals, such that the protruded blade tightly contacts an object to be crushed and prevents the object from sliding when said object is introduced by the inlet roller, thereby increasing the object-holding force. An inlet unit has an increased tilt angle to reduce the object-cutting angle, to thereby reduce vibrations and noise during cutting and to cut the object more quickly.

The present invention relates to a tree branch crusher in which the crushed material is crushed more quickly and efficiently by inclining the input angle of the hopper.

Fruit farmers pruned each year to improve fruit harvest. Tree branches cut by pruning are crushed by a crusher and sprinkled on the ground. Many fruit farms with more than a certain size have a crusher for crushing tree branches, and the performance of the crusher greatly affects the work efficiency of the fruit farm.

Many technologies have been patented or applied for shredding a tree branch, and various kinds of shredders are sold. There are various types of wood shredders, from crushing large timbers to crushing small and medium tree branches. Especially, fruit trees farmers use many small and medium tree branch shredders.

Conventional medium and small tree branch shredders have a problem of slow crushing speed and severe vibration and noise in the process of crushing tree branches. In addition, there was a problem of frequent failures and poor durability. This is the biggest cause of the inlet roller and the crusher cutter mounted in the conventional tree branch crusher.

Typically, a tree branch shredder is equipped with a flywheel 210 weighing about 50 kg on the outside of the shredder cutter receiver 400. In contrast, the crusher according to the present invention is equipped with a pair of flywheels 210 inside the crusher cutter accommodating portion 400, in which case, the weight of one flywheel 210 is preferably 30kg to 80kg. Since the total weight of the flywheel 210 is 60kg to 160kg, the flywheel 210 is heavier than the conventional crusher. If the weight of the flywheel 210 is large, it becomes more efficient in crushing the thick tree branches, which in the present invention, the flywheel 210 is mounted inside the shredder cutter receiving portion 400, integral with the blade portion 220 It is possible because it is combined form. However, when the weight of the flywheel 210 is too large, the total weight of the crusher becomes large and is not preferable because the movement is restricted.

The flywheel 210 of the shredder cutter 200 according to the present invention has a rotary shaft holding portion 211 formed to surround the rotary shaft 230 in the center of the inner surface of the flywheel 210, and the rotary shaft holding portion 211 The side of the rotation axis 230 is coupled to the direction of the rotation shaft 230 is preferably configured to further comprise a fixing screw 212 for fixing and coupling the flywheel (210).
