Description

[Detailed description of the invention] This invention relates to a mobile garden cleaner, and its purpose is to separate and collect objects to be collected, such as dead leaves, fallen leaves, paper scraps, etc., and non-collectable objects, such as pebbles. .

Generally, when garden cleaners are used to collect dead leaves, paper scraps, etc. from gardens and parks, there is a problem with incineration after collection because pebbles are also collected at the same time, and in the case of gardens, the pebbles gradually disappear. There is.

This proposal has been made in view of the above points, and the embodiment shown in the drawings will be described below.

Reference numeral 1 denotes a main body case provided with a pair of running wheels 2 and 3 at the front and rear, respectively, and is composed of an upper case 4 and a lower case 5.

The main body case 1 is divided into two upper and lower chambers by a partition plate 6, and an electric motor 8 is housed in an upper chamber 7, and a pressurized blower 10 driven by the electric motor 8 is housed in a lower chamber 9, respectively.

An intake port 11 of the blower 10 is provided on the lower surface of the lower chamber 9, that is, the lower case 5, and an exhaust port 1 is provided on the back surface.
2 is shaped, and both the intake and exhaust ports 11 and 12 are connected to the air passage 1.
3.

Reference numeral 14 denotes a breathable collection bag detachably connected to the exhaust port 12, and the bottom of the bag is removably locked to a push handle 15 attached to the upper rear surface of the main body case 1.

An enlarged part 16 in which the suction pressure drops rapidly is formed in the middle of the air passage 13, and a plurality of holes 17, 17, . . . are provided in the lower part of the enlarged part 16.

In the above structure, the pressurized blower 10 is rotated by the rotational drive of the electric motor 8, and the static pressure at the inner diameter portion is reduced, thereby generating a suction force. and objects other than the objects to be collected, such as pebbles, which correspond to the suction force are mixed and sucked in from the suction port 11.

The collected objects sucked into the pressurized blower 10 are blown into the air passage 13 by the high dynamic pressure generated at the outer diameter of the blower 10.

Dead leaves, fallen leaves, paper scraps, pebbles, etc. carried by the air flow flow into the enlarged portion 16 in a mixed state.

Since the enlarged portion 16 has a more rapid change in volume than the air passage 13, a significant drop in dynamic pressure occurs.

Therefore, the ability to send relatively heavy pebbles, etc. to the collection bag 14 is lost, and the pebbles, etc.
．． 17... Light objects to be collected, such as dead leaves, fallen leaves, and paper scraps, are collected in the collection bag 14.

As mentioned above, the mobile garden cleaner according to the present invention has the following features:
The air intake and exhaust ports of the air blower are provided on the lower and back surfaces of the main body case, which has a built-in electric blower and running wheels at the front and rear, and ventilation is provided between the exhaust ports and the hand handle provided on the upper rear surface of the main body case. The collection bag is removably attached, and the air passage that communicates the intake and exhaust ports has an enlarged part with a hole on the bottom, so it is easy to collect dead leaves, fallen leaves, paper scraps, etc. If objects to be collected and objects not to be collected, such as pebbles, can be sorted and collected in collection bags, and incineration after collection can be easily performed, pebbles and other objects will not be collected. The beauty of the garden etc. will not be spoiled as it will be returned to the original state.
