Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tree shredding machine that can easily shred leaves, twigs, trunk branches, or kitchen waste.

In general, crushers have a myriad of structures depending on the material being processed, but in recent years the amount of tree debris and kitchen waste generated from households has increased, making it easier for households to dispose of them and convert them into fertilizer. There was a demand for a small machine that could shred them.

The present invention is intended to meet such demands, and its configuration will be described in detail below with reference to the accompanying drawings.

A bearing arm (3) with an engine (2) attached to one side is fixed on the support leg (1).

A cutting disk (5) is vertically attached to the tip of a rotating shaft (4) that projects on the other side of this bearing arm (3).

In this case, in the drawing, the driving shaft of the engine (2) is a rotating shaft (4), and this rotating shaft (4) is supported by a bearing (6) attached to a bearing circle (3). The rotation of the engine (2) may be transmitted to the rotating shaft (4) via a rotation transmission mechanism.

Further, the same effect can be obtained by using a motor that drives the rotating shaft (4).

The radial direction of this cutting disk (5) (two cutting flat blades (7)
) will be established.

The drawing shows two flat cutting blades (blade plates (8) with force applied to their long edges) attached along the approximate diameter line of the cutting disc (5), and a cutting disc (5) located just in front of each blade edge. 5) is formed with a notched relief hole (11) through which the shredded material (9) passes and is removed in the radial direction.

Moreover, a discharge blade (13) is attached to the back surface of the cutting disk (5) to blow off the shredded material (9) and send it to the discharge port QZI of the cutting case (11), which will be described later.

A rising blade Q4) is provided at the center of the cutting disk (5) in a state substantially perpendicular to the cutting disk (5) and protruding in the direction of extension of the rotating shaft.

The drawing shows a case in which blade plates 9 are connected to the left and right edges of the connecting plate part in an open state and in a rising state, and a rising blade I is attached to one side edge of each blade plate ttS.

A cutting case αυ that covers these two blade plates (8) α9 is provided on the bearing circle (3) (removable with the clamp device 1 mark) so that the blade plates (8) α9 can be easily replaced, and When the case (the shape of lυ is formed flat with respect to the cutting disk (5) so that the objects to be shredded such as twigs and leaves are pressed against the two blade plates (8) Q5) by their own weight. It shows.

A hopper 〇 into which twigs, leaves, etc. are thrown is provided at the top of this cutting case 01J.

A branch insertion tube into which objects to be shredded, such as thick branches and trunks, are inserted into the middle part of this cutting case ← D, whose lower end is in the center of the cutting disk (5), and whose upper part projects beyond the cutting case I. Install H diagonally.

A discharge port 2 for shredded material (9) is provided at the bottom of the cutting case aυ.

In the figure, the symbol - is a handle, and the can is a blocker that prevents the flat cutting blade (7) from biting the object to be shredded (17) (17)'.

Since the present invention is configured as described above, when the engine (2) is started and relatively small objects to be shredded (17) such as twigs, leaves, reeds, dry weeds such as awns are input into the Hora A-us, The shredded material (9) is stored in a cutting case αυ, and a cutting flat blade (7) attached to a cutting disk (5) rotating at high speed inside this case is used.
) and the rising blade α4142.

Since the lower part of the cutting case I is provided with a discharge port, the shredded material (9) into chips is transported through the discharge port α.
It will be discharged outside from the tank.

In other words, if relatively small objects to be shredded [η] are successively fed into the hopper (lF91m), they will be immediately transferred to the two blade plates (8) α
After being shredded in step 9, the shredded material (9) is also continuously discharged.

In addition, objects to be shredded such as relatively large and thick branches and trunks that do not fit into the hopper 08 can be inserted into the branch insertion tube (11), and the lower end of the inserted thick branches and trunks is The shredded material (9)
will be shredded again by the flat cutting blade (7) and discharged from the discharge port ←.

In this case, since the lower end of the branch insertion tube (11) is provided with the lower end facing the center of the cutting disk (5), the lower end of the object to be shredded aη' inserted into the branch insertion tube a1 will always be cut by the blade plate (8) with a large torque. Since it presses against the warm part of α, even hard objects such as thick branches and trunks can be shredded effectively.Therefore, even if the engine (2) with a small horsepower is used to drive the rotating shaft (4), it will not be enough. The shredding ability will be obtained, and this machine will be able to be designed as a Combaku F.

In addition, since the two blade plates (8) ffs rotate while maintaining a state substantially orthogonal to each other, the objects to be shredded aηa are kept in the cutting case αυ.
F. No matter what posture the half-opened object is in, it will be cut vertically or horizontally, so everything in the cutting case aUU will be shredded, resulting in extremely high-quality shredding. It turns out.

Thus, according to the present invention, small branches, leaves, kitchen waste, thick branches, and trunks can be shredded easily, efficiently, and with high quality (7), and it can also be easily miniaturized. This provides a tree shredding machine that is highly effective for home use.
