Description

Pneumatic mowing unit and cleaning car using the same

The present invention relates to a mowing device, and more particularly, to a mowing unit using high pressure capable of removing weeds on the edge of a road by piggybacking on high pressure air with water or sand, and a cleaning vehicle using the same.

In general, a mower is a mechanical device for cutting weeds and weeds growing on the edge of a road, a garden, a head of a paddy field, etc., and has a small engine and a cutting blade so that a worker can wear it.

Korean Patent Publication No. 10-2012-0033612 discloses a lawnmower. The posted lawn mower includes a frame on which a backrest is mounted, an engine unit rotatably mounted on the frame to rotate the main rotating shaft by a starting device, and one end of the main rotating shaft of the engine unit to apply the rotational force of the main rotating shaft to the blade. and a blower fan connected to the other end of the main rotating shaft to suck outside air in association with the rotation of the main rotating shaft, and to discharge it through a discharge pipe as having a power transmission unit capable of transmitting it.

In addition, the Korean utility model No. 20-0344932 (registered on March 3, 2004) and utility model No. 20-0336992 (registered on March 13, 2003) of the Republic of Korea Utility Model No. 20-0336992 (registered on March 13, 2003) have posted mowers, and the Korean Patent No. 10-1320993 has a power mower. has been posted

In addition, Korean Patent Registration No. 10-1416664 discloses a device for collecting cut grass and a powered lawn mower using the same.

Since these mowers or lawn mowers cut weeds, brushes, and grass by using a cutting blade, the working efficiency varies depending on the state of the cutting blade or the skill level of the operator. In the case of a cutting blade for removing weeds, as the use continues, abrasion occurs, so periodic management is required, and there is a problem in that a large amount of cost is required for maintenance.

In particular, when a guide rail is installed on the edge of a road, such as a highway, national road, or local road, in order to remove weeds, arrowroot vines, and weeds that grow on the outside centering on the lower part of the guide rail or the road boundary stone, the operator uses the conventional method as described above. There is a problem in that the work efficiency is relatively low because the work is performed using a lawn mower.

On the other hand, sand, soil, garbage, etc. are relatively collected at the edges of highways and national roads, that is, boundary stones, and the garbage is periodically cleaned by a cleaning vehicle. In this process, since sand or soil is collected like garbage, a separate separation operation is required, and thus the efficiency of the cleaning operation cannot be improved.

In particular, a certain amount of the mowing core is supplied in a uniform amount through the screw, and the mowing core 100 due to the negative pressure generated by the high-pressure air supplied through the pneumatic pipe 51 to the throttle part of the core suction member 47 . ) is smoothly supplied, and it is possible to prevent clogging by being stacked inside the mowing supply pipe 61 .

In this operating state, the high-pressure air supplied through the high-pressure pipe 51 is injected at high pressure through the mowing nozzle part 45, and the mowing core 100 is piggybacked on the high-pressure air that is sprayed to mower. sprayed as weeds for In this way, weeds are cut by the high-pressure air on which the mowing core is sprayed. That is, the mowing core, which has a high-pressure, high-pressure, and ride-through on the sprayed air has a large kinetic energy according to the speed, so it cuts the weeds when they collide with the weeds.

The weeds cut by the action as described above are blown away from the edge of the road by the high-pressure air being sprayed.

The pneumatic mowing unit and the cleaning vehicle using the same according to the present invention configured as described above clean the road, store the sand or soil collected during cleaning with garbage, and spray it at high pressure to remove weeds. efficiency can be improved accordingly. In particular, there is no need to separately remove the removed weeds as in the prior art because the removed weeds can be blown away by riding on high-pressure air.

Although the present invention has been described with reference to the embodiment shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible therefrom. Therefore, the true technical protection scope of the present invention will have to be determined by the technical spirit of the appended claims.
