Description

Prefabricated muti-tasking device

The present invention relates to a small work machine that can be used as a snow removal device, and more particularly, by configuring a small work machine including a detachable power supply device, a main body and an accessory device to facilitate the use of the work machine by replacing the accessory device. The present invention relates to a prefabricated multi-worker that can be changed as well as provide convenience of repair and replacement in the event of failure of some components of the small work machine.

Snow plows are used to clear large amounts of snow on the road due to heavy snow. In general, a snow plow consists of a snow removing plate for pushing snow accumulated on a road surface to an outer shoulder, and a coupling part for coupling the snow removing plate to a vehicle. That is, the snow removing operation is performed while moving along the road surface by mounting the snow plow on the vehicle.

Using the snow plow has the advantage of removing a large amount of snow at a time, but there is a problem that can not remove the snow accumulated around narrow roads, sidewalks or buildings. In addition, the snow removal operation using the snow removal machine has a problem that can not remove the snow accumulated on the golf course difficult to enter a high weight vehicle.

To solve this problem, small snow plows are used. In particular, the recent small snowplow is equipped with an engine or a motor for the convenience and efficiency of snow removal.

The small snow plow is generally manufactured in one piece for easy operation or convenience of movement. However, when the integrated small snow plow has a defect in a part of the small snow plow, not only the whole small snow plow may be used, but also there is a problem in that the entire small plow is replaced.

In addition, since the integrated small snow plow is difficult to attach and detach the already mounted engine, there is a problem that it is difficult to repair or replace with a new engine when the engine fails.

In addition, since integrated engines and snow plows are generally designed to be used only for the plows, it is difficult to upgrade to an engine having a higher horsepower when a job requiring more power is required. There is this.

In addition, when the small snowplow is equipped with an engine or a driving motor, it is difficult for a person to move alone.

As shown in FIG. 1, the prefabricated multi-worker according to an embodiment of the present invention includes a power supply device 100, a main body 200, and an accessory device 300. The power supply device 100 and the accessory device 300 may be detachably attached to the main body 200 of the prefabricated multi-worker according to the present invention.

1 and 2, the power supply device 100 is centrifuged to transfer the driving force generated in the power supply device 100 to the body 200 after the power supply device 100 and the main body 200 are combined. A clutch (Centrifugal Clutch, 150) can be employed. When the power supply device 100 and the main body 200 are coupled, the centrifugal clutch 150 is inserted into the power receiving shaft 221. In addition, the main body 200 may employ the power take-off device 241 to transfer the driving force to the accessory device 300 after the main body 200 and the accessory device 300 is coupled. The power take-off device 241 is coupled to the connecting unit 310 to transfer the driving force to the accessory device (300).

Referring to FIG. 1, the main body 200 includes a frame 210, a power receiving unit 220, a power distribution unit (not shown), and a power transmission unit 240. The frame 210 maintains the shape of the main body 200, and the power receiving unit 220 and the power transmission unit 240 are provided at one side and the other side of the main body 200.

The power receiving unit 220 is provided at one side of the frame 210 and is coupled with the power supply device 100 to receive a driving force from the power supply device 100. The manner in which the power receiving unit 220 is coupled to the power supply device 100 is not limited in the coupling manner such as fitting coupling or coupling through a fixing clip. Additional bolt coupling may be applied to secure the power supply 100 to the power receiver 220 more firmly. After the power receiving unit 220 and the power supply unit 100 are combined, the driving force generated in the power supply unit 100 can be easily transmitted to the power receiving unit 220, so that the power receiving unit 220 and the power The driving force may be transmitted between the supply apparatuses 100 through the centrifugal clutch 150.

In more detail, the power supply device 100 includes an engine unit 110 for generating a driving force. The driving force generated in the engine unit 110 is transmitted to a rotating shaft (not shown) connected to the engine unit 110, and when the centrifugal clutch 150 is employed in the rotating shaft, the driving force is transmitted to the centrifugal clutch 150.

The power receiving unit 220 is provided with a power receiving shaft 221 for receiving a driving force from the rotating shaft. When the centrifugal clutch 150 is employed as the rotating shaft, when the power receiving unit 220 and the power supply device 100 are coupled, the centrifugal clutch 150 is accommodated in the power receiving shaft 221. The centrifugal clutch 150 selectively transmits the driving force to the power receiving shaft 221 in accordance with the rotational speed of the rotating shaft. The centrifugal clutch 150 transmits the driving force to the power receiving shaft 221 only when the rotation speed of the rotating shaft is greater than or equal to the threshold value. When the engine speed is low, the centrifugal clutch 150 cannot transmit torque because the centrifugal force is smaller than the force of the return spring. However, when the engine speed is increased, the centrifugal clutch 150 starts to be pushed onto the fuselage of the clutch to receive the power shaft 221. The torque is transmitted while sliding inside. In addition, if the rotation speed increases, the force of the return spring is pressed and the slide is lost and the torque is transmitted completely.

The power distribution unit is located inside the frame 210. The power distribution unit distributes the driving force transmitted from the power receiving unit 220. The power distribution unit may include a spur gear, a curved bevel gear, an internal gear, a sprocket, a straight bevel gear, a timing gear, a helical gear, and the like, and thus the magnitude of the driving force or the direction in which the driving force is transmitted may be changed.

The power transmission unit 240 is provided on the other side of the frame 210 and combines with the accessory device 300 to transmit the driving force distributed from the power distribution unit to the accessory device 300. The power transmission unit 240 is not limited in the manner of coupling with the accessory device 300, the coupling method, such as through the fitting coupling or fixing clip. Additional bolt coupling may be applied to more firmly secure the accessory device 300 to the power transmission unit 240.

The power take-off device 241 may be employed in the power transmission unit 240 so that the driving force can be easily transmitted to the accessory device 300 after the power transmission unit 240 and the accessory device 300 are combined.
