Description

  The present invention relates to a pulverizer, and more particularly, to a pulverizer using a motor powered by a household AC power source for pulverizing bulky garbage from homes, branches and leaves after pruning garden trees, and the like. is there.

  Conventionally, a wood crusher as disclosed in Japanese Patent No. 2703708 is known as this type of crusher. In the crusher of this patent, two support plates are fixed to a rotating shaft supported in a horizontal direction in a crushing case, and a supporting shaft penetrating in a direction parallel to the rotating shaft is provided at a predetermined radial position. A rectangular crushing blade with blades at four corners is supported swingably by a support shaft passing through one of two support holes provided at symmetrical positions. It is locked in the axial direction. The support shaft is fixed to the support plate by a pin penetrating with the collar.

  Further, the rotating plate is fixed to the rotating shaft, the vane plate is fixed to the inner side surface (supporting plate side) of the rotating plate to form a fan, and the outer surface includes a radial line including the axis and a predetermined line. A scissors blade is fixed so that a blade edge may be located on the parallel line of a space | interval, and a long hole is provided along the blade edge. An inclined surface is formed in a concave shape along the long hole in the direction of the long hole, away from the surface of the rotating plate (in the direction in which the thickness of the rotating plate increases), and the edge opposite to the long hole. A step portion for locking the scissors blade is formed on the portion, and the scissors blade is fixed to the inclined surface by a bolt.

  A crushing hopper opens at an outer peripheral position facing the crushing blade of the crushing chamber, and a plurality of anti-scattering walls are arranged in parallel at appropriate intervals in a position facing the crushing blade on the outer wall of the crushing hopper. The crushing hopper is formed to have a square cross section, and is provided so as to be divided for each side plate of each side.

  A cutting hopper for inserting a slightly larger diameter medium-diameter branch trunk or the like and cutting the end surface with the scissors blade is opened at a position facing the scissors blade on the side surface of the cutting chamber.

  A partition wall having a circular opening at the center is provided between the support plate and the rotating plate, and a plurality of notches are formed at the inner diameter edge of the opening. The crushing blade on the fan side is provided close to a predetermined distance facing the notch. The crushing case is divided into a crushing chamber and a cutting chamber by a partition wall.

  In order to crush pruned twigs and the like, the twigs that are put into the crushing hopper are crushed by a crushing blade that is rotated by an engine, sucked into the fan through the opening of the partition wall, and discharged from the discharge shooter along with the air blowing. When a large crushed piece enters the opening, the crushed piece that tries to rotate with the crushing blade engages with the notch at the inner diameter edge of the opening and is prevented from rotating. Disconnected.

  When the medium-sized wood piece is pushed in from the cutting hopper, it is cut by the scissors blade in order from the tip, and the cut piece is discharged by the fan through the long hole.

  In the wood crusher of this patent, since the rotating plate rotates at a high speed, there is a possibility that the user may be injured if the hand is put into the crushing cylinder from the insertion port. In addition, since large vibrations and impacts are generated when dust comes into contact with a rotating plate (blade) that rotates at high speed, when a long branch is inserted, vibrations and impacts are transmitted to the branches and the user feels fear.

  If the input port is narrowed or the path from the input port to the crushing cylinder is bent to make it difficult for the operator's hands to enter, if a small object such as a bulky leaf is input, the phenomenon of clogging near the input port may occur. Occurred.

  Another example of a small tree shredder is shown in Japanese Patent Publication No. 61-44641.

A rising blade is provided so as to protrude in the direction of extension of the rotation axis in a state substantially orthogonal to the cutting disk. In addition, a hopper for inserting twigs, leaves, etc. is provided at the top of the cutting case, with the lower end facing the center of the cutting disc at the middle of the cutting case and the upper part protruding out of the cutting case, A branch insertion cylinder for inserting shredded objects is provided obliquely.

However, even in this tree shredding machine, the rotating plate rotates at a high speed, and there is a possibility that the user may be injured if the hand is put into the pulverizing cylinder through the slot. For this reason, if the inlet is made narrow for safety or if the path from the inlet to the pulverization cylinder is bent, there is a possibility that a small and bulky material such as a leaf will be clogged in the vicinity of the inlet. In addition, a large vibration / impact occurs when dust comes into contact with a rotating plate (blade) that rotates at high speed. For this reason, when a long branch or the like is thrown in, a vibration or impact is transmitted to the branch, and the user may feel a fear.
