Description

Tractor loader detachable snow removal device {SNOW REMOVAL DEVICE}

The present invention relates to a snow removal apparatus used while being attached to and detached from a loader of a tractor, and more specifically, a detachable use corresponding to various width sizes of a loader is possible, as well as both sides of the snow removing plate are adjusted up and down according to the slope of the road surface. The present invention relates to a tractor loader detachable snow removing device that provides a close and effective snow removing operation and an effective buffering operation of a snow removing plate against road obstacles.

In general, a conventional snow removal apparatus is used to attach snow removal blades to a vehicle or the like to collect and process snow accumulated on a road surface.

Such a snow removing device has been disclosed in various forms, and as disclosed in Korean Patent Laid-Open Publication No. 2000-50462, the A-type connecting rod is formed to be attached to the rear side of the snow removing plate so that the left and right angles are adjusted by a cylinder.

The snow removing plate is configured such that the fixing rod to which the snow removing blade is attached to the lower portion pivots against the obstacle on the road surface by the buffer means,

On both sides of the rear surface of the snow removing plate is made of a wheel for maintaining the distance between the snow blade and the road surface.

Such a snow removing device is installed by using the A-type connecting rod in a vehicle, and moves together with the vehicle to collect and process snow accumulated on the road surface by the snow removing plate, while the snow removing plate is processed while adjusting the left and right, vertical angle.

In addition, during the snow removal operation, the snow removal operation of the snow removal blade attached to the bottom of the snow removal plate is performed by the buffer means while the snow removal operation is performed in a state of preventing the impact on the obstacle.

However, the snow removal apparatus directly connects the snow removal plate to a vehicle or the like by simply using the A-type connecting rod. When the A-type connecting rod does not fit with the vehicle connecting portion, the combined installation is difficult, and thus it cannot be used universally. There was this.

In addition, the snow removal apparatus is used by simply adjusting the snow removal plate to the left and right, up and down angle, it is possible to work in a place where the road surface is relatively flat, but when the road surface is inclined or irregular, especially on the road of rural farmhouses There was a disadvantage that can not perform effective snow removal work without being in close contact with.

In addition, since the snow removing device rotates only the lower snow blade of the snow removing plate so as to alleviate the impact caused by hitting an obstacle on the road surface, there is a problem that the impact is applied to the snow removing plate in the case of a relatively large obstacle.

On the other hand, in the Utility Model Registration No. 20-0171851 is a snowplow plate is connected to the main frame connected to the front of the vehicle to the vertical angle adjustment bar so that the entire snowplow plate is cushioned while climbing up and down by the angle adjustment bar against the obstacle.

However, such a device buffers an impact on an obstacle while the entire snow removing plate moves up and down, and thus, the impact transmission on the obstacle is greater than the rotation of the snow removing plate, and it is difficult to buffer the relatively large obstacle. In addition, the above-described device can also be connected to the mounting plate formed on the front of the vehicle only the main frame constant, if the width size of the interconnection portion does not match, it is difficult to install the connection, the snow removal plate is also raised and lowered constantly It still has a problem that effective snow removal is difficult when the road surface is inclined or irregular. In addition, US Patent No. 4,87,624 also hinges the support frame in which the snow removal plate is installed in front of the coupling frame on the front of the vehicle. Coupled to the snow removal plate by the left and right cylinders Both ends are adjusted back and forth, and the upper and lower sides are adjusted by the central cylinder. The apparatus also has a relatively large obstacle because the snow removing plate performs a buffering operation by a spring against the obstacle, but the rotation operation is not provided. There is a problem in the impact mitigation, and the snow removal plate can be connected to the front of the vehicle only uniformly, if the width size of the interconnection portion does not match, it is difficult to install the connection, the snow removal plate is adjusted to raise and lower constantly Therefore, when the road surface is inclined or irregular, effective snow removal is difficult.

The present invention was created in order to solve the above-mentioned problems of the prior art, and effectively connected and installed while adjusting the width direction position of the detachable part according to the width size of the tractor loader, as well as effectively buffering the entire snow plow plate while rotating against obstacles. The purpose of the present invention is to provide an operation, and to allow the sides of the snow removing plate to flow up and down as well as up and down, and to be in close contact with the road surface even in an inclined or irregular road surface state so as to effectively perform snow removal work.

The object of the present invention is to connect to the loader of the tractor, but to adjust and connect the position of the removable parts on both sides of the support frame according to the width size of the loader, the center of rotation axis installed in the width direction from the front of the support frame to the obstacle As the snow removal plate rotates as a whole and buffer operation, the snow removal plate is achieved by a snow removal device in which both sides are inclined or close to the irregular road surface while moving up and down as well as moving up and down.
