Description

[Detailed description of the invention] "Industrial application field" The present invention relates to a suction type vacuum cleaner for cleaning dead leaves.

``Prior Art'' A suction type vacuum cleaner for cleaning fallen leaves according to Japanese Patent Application No. 63-50152 filed earlier by the applicant sucks fallen leaves from a suction cylinder, and has a rotary blade with a cutting blade and a fixed blade inside. This is a portable vacuum cleaner that guides the vacuum cleaner into the suction chamber where the vacuum cleaner is cleaning and cuts the wood mixed in the fallen leaves into small pieces to prevent the wood from clogging the suction chamber and making suction impossible.

``Problem to be solved by the invention'' Fallen leaves enter the C duct chamber from the suction tube through the suction chamber,
The garbage is stored in a garbage bag placed over the duct room, and if the fallen leaves are in a wide area, a suction port with a wide frontage and depth is used; This has the inconvenience of forming a narrow suction port and requiring replacement and attachment to the suction cylinder as necessary. Also, when dead leaves are still attached to the tree, it is necessary to knock them off and suck in C. Also, it is a powered portable device.
If you hang the machine on your shoulders for a long time, you will get tired and the vibrations are quite strong, which may have a negative effect on your body.

"Means for solving the problem" A rotary blade with a cutting edge is provided in the suction chamber, and a short cylindrical part integrated with a covering member with a wide area that contacts the ground K and surrounds fallen leaves is communicated with the suction chamber, and grooves are connected to the suction chamber. A suction pipe equipped with a narrow suction port for sucking fallen leaves in narrow spaces such as places is connected to the short cylinder part, and a shutter that can be opened and closed to block the flow path of the short cylinder part is installed at the discharge port of the suction chamber. Connecting the silencer, further covering the silencer with a bag, and providing an opening in the wall of the suction chamber and providing a switching shutter that alternately closes the discharge port and the opening,
An air blowing cylinder connected to a hose for blowing off dead leaves is fixed to the wall of the suction chamber with the opening covered, and the lower part of the suction chamber is mounted on a trolley equipped with a tiltable pusher, and the engine is placed above the suction chamber. Alternatively, a power section consisting of a motor is mounted on the tower to drive the C rotary blade, and a fixed blade for cutting the wooden cane is provided inside the short tube section.

``Operation'' Adjust the pusher at an appropriate angle and press it, place the covering member over the fallen leaves, and suck the fallen leaves into the suction chamber through the connecting member. Cut with a blade and release the shutter provided with the short tube that communicates with the fallen leaves in the groove etc. [Suck in from the short tube and remove the sucked fallen leaves and wood chips from the outlet of the suction chamber into the storage bag. Store it in. Dry leaves attached to the tree are blown off with the air released from the hose and stored in a storage bag from C.

``Embodiment'' To explain an embodiment of the present invention with reference to the drawings, a rotary blade (1) having a cutting edge formed on the edge is pivotably supported in a suction chamber (2) consisting of a spiral chamber. The rotating blade (1) is rotated by the engine or motor {3} mounted on the tower, and the chamber (
2) to communicate. A suction pipe (not shown) equipped with a suction port that can be inserted into a narrow space such as a groove is connected to the short cylinder part (6) K that communicates with the side of the suction port (41), and the short cylinder part (!1 ) The end of the shack {6) which blocks the flow path of
When the shutter 16》 is raised and the flow path is opened, the droplets are sucked into the suction chamber (2》) from both the cover member 《4》 side and the short cylinder part (6》 side).The appropriate place of the shutter (6) and the suction port (
The closed state and the released state of the shutter 1g) are fixed by installing the tension spring 11》 across the appropriate position K in 4b). Attach the fixed blade 18 on the upper surface of the cover member (4) at a position close to the cutting edge of the inner blade and rotary blade C, and
Cut the mixed wood to prevent it from clogging in the suction chamber. A switching shutter +11 that fits the discharge port (2a) of the suction chamber (2) with a silencer (1g) with a K handle and blocks the communication path between the discharge port (2a) and the silencer +111.
is pivotally supported by the discharge port (2a) part K support M (loa).

In addition, cover the silencer (I1) with a plastic bag to store leaves.

1+ Both ends of the support shaft (10c) of the switching shutter I1 are made to protrude, and a lever (lob) is fixed to one shaft end, and a panel fixing piece (10c) is fixed to the other shaft end, and the suction chamber (2) is fixed.
upon! ! A K opening (2b) is provided, and an air blowing tube (l1) for blowing off dead leaves attached to trees is integrally fixed to the upper wall of the suction chamber (2) so as to cover the opening (2b), and is fixed with a panel. A tension panel I is stretched between the fitting piece (10c) and the air blowing tube (11) at a suitable location. Switching shirt lock O
When the CI covers the opening (2b), the sucked fallen leaves pass through the discharge port (2a) into the muffler (9), and the switching shutter that enters the bag opens the discharge port (2a). Even when the air is covered, only air is sucked into the K suction chamber (2) and injected from the C air blowing tube (■). On the axle (12b) of a forked trolley Q-shaped (12b) equipped with a pusher (12a),
Legs (2c x 2c) integrated at the bottom of the suction chamber (2)
) with the pressure contact member land interposed and C fixed, stirring (12a)
Hold it at any angle and fix it. The pressure contact force of the pressure contact member 1 is adjusted by the pressure contact member (lm is a tension panel Q4 stretched between the two forks of the vehicle chassis θ). Fallen leaves in a place can be covered with a rotating blade (1) by covering it with a covering member +4》
The negative pressure generated by the rotation of the blades causes the wood to be sucked into the suction chamber (2), and fallen leaves are cut into the suction chamber (2) by the cutting blade and fixed blade (1B) provided on the edge of the rotating blade (1). (2)
You won't get clogged with work and become unable to absorb. Fallen leaves in a narrow place such as a ditch are sucked in through a suction pipe connected to the short cylinder part (6) by opening a shutter (6) that closes the short cylinder part (5). The fallen leaves sucked into the suction chamber (2)K pass through the silencer (9) from the discharge port (2a) and are stored in a covered bag.
It can be removed and collected easily.

At the same time as releasing the shutter (6), the discharge port (2a) is closed by the switching shutter (10), and only the air is sucked in from the short tube part (5), and the dead leaves attached to the tree are removed from the air blowing tube (+l). When spraying, dead leaves easily fall off, and the fallen leaves can be sucked into the suction chamber (2) for cleaning.Also, since the vacuum cleaner body is mounted on a trolley θ, it is easy to move, and the pusher (12a) It can be tilted and fixed freely, depending on whether it is towed or pushed, or depending on the difference in height.It can be held at an appropriate angle to work in a comfortable posture.

As described above, the present invention is a useful invention that has a strong and durable structure, operates reliably, and is easy to manufacture.
