The present invention has the following effects.
1. Since it is attached to a truck and used, it can remove snow without purchasing a new snowplow.
2. Each component is removable, so it can be removed from the truck and stored when not in use, such as in summer, and the storage space is small.
3. It can be used and run as a general truck by removing each member.
4). The raising and lowering of the snow pushing plate and its angle adjustment are possible, and not only mere snow pushing but also work such as snow pile, snow rake, and snow pulling can be performed.

Hereinafter, embodiments of the present invention will be described.
In the figure, reference numeral 1 denotes a frame formed by joining iron hollow squares into a square frame shape, which is joined to an existing frame part located at the front of the truck bed, and slightly above the frame part. The edge is located. Reference numeral 2 denotes a pulley support, which is formed by bending a flat plate into a U-shape and joining it on another rectangular flat plate with the lower end of the bent downward. A through hole is formed near the center of the side surface of the pulley support, and the shaft 3 is inserted and held in the through hole. Reference numeral 4 denotes a first pulley having a U-shaped groove on the outer periphery of the cylinder and a hole in the center thereof, and the shaft 3 is inserted and held in the hole.
The outer diameter of the shaft 3 is slightly smaller than the inner diameter of the hole of the pulley, and therefore the pulley 4 is rotatable with respect to the shaft 3. Four holes are drilled in the lower plate portion of the pulley support, and female screws are similarly engraved in the center of the upper surface of the frame and in the vicinity of both ends, as shown in FIG. The pulley support is screwed to the body 1 with bolts.
Reference numeral 5 denotes a support, which is formed by connecting a pair of elongated iron plates formed obliquely below the support with connecting short plates. Above the column, the second pulley 6 is pivotally supported in the same configuration as the pulley support described above, and a pair of female screws are engraved slightly below. Moreover, a hole is drilled in the oblique portion side surface.

7 is a stay, and a pair of left and right is provided. This stay is an elongated hollow rectangular body, and a rectangular plate 8 is fixed to the lower surface in the vicinity of one end, and a hole is formed in the small plate. The other end side surface of the stay has a surface cut obliquely with respect to the side surface of the stay. A through hole is formed on the side surface opposite to the oblique surface. As shown in FIG. 1, the stay is symmetrically screwed at one end to the upper surface of the frame 1 and the other end to the upper side surface of the column via a hole.
A box-shaped winch box 9 is arranged and fixed in contact with the frame body, and a commercially available electric winch 10 is provided in the inside. 11 is a steel rope, one end of which is fixed to a winch take-up drum, passed through a hole in the upper part of the winch box, spanned between the first pulley and the second pulley, and extended downward to be described later. It is locked to.
Reference numeral 12 denotes a frame holder. This frame holding body is a substantially rectangular object in plan view in which a hollow rectangular body and a flat plate are appropriately joined, and five pairs of mounting plates 13 to 15 are positioned on the front surface thereof, and through holes are formed on the side surfaces of the mounting plate. Drilled. Further, the frame holder is appropriately screwed to the lower front part of the track, and members and holes for this screwing are appropriately provided. The lower portion of the support column 5 is pivotally supported on the mounting plate 13 at the center of the frame holder.
The structure from the frame body 1 to the mounting plate 15 described above constitutes a snow removal device lifting mechanism.

Next, the snow removal device will be described.
In the figure, reference numeral 20 denotes an iron plate snow pushing plate. The snow pushing plate is formed by joining a substantially semicircular plate on both sides of a substantially arc shaped plate, and a perforated rope holding plate 21 and a pair of perforated frames at appropriate positions on the outer surface of the arc shaped plate. A holding plate 22 and a pair of perforated arm holding plates 23 are joined to each other. Reference numeral 24 denotes a frame. This frame is formed by joining hollow horns to form a square frame, and by joining reinforcing members on the diagonal lines, and holes are drilled at appropriate positions, and these holes and holes of the mounting plate 14 of the frame holder, And it is pivotally supported with the holes of the frame holding plate aligned.
A cylindrical outer arm 25 is provided with holes in the vicinity of both ends thereof. Reference numeral 26 denotes an inner arm, and pin holding holes 27 are formed in the side surface at regular intervals. The inner arm outer diameter is slightly smaller than the outer arm inner diameter, so that the inner arm can slide in the outer arm. Further, the hole in the vicinity of one end of the outer arm is axially supported so as to coincide with the hole of the mounting plate 15. The hole at one end of the inner arm is pivotally supported in alignment with the hole of the arm holding plate, the hole of the outer arm is aligned with the selected hole of the inner arm, and a substantially cylindrical pin 28 is inserted, and the inner arm with respect to the outer arm is inserted. The position of is regulated.
The snow removal device unit is configured from the above configuration.

In order to use the present invention, first, as shown in FIGS. 16 to 17, each member and the like are attached to the truck, and then the snow removal device is attached to complete preparation. Then, when the truck is run in a place where snow is to be removed, the snow pushing plate pushes the snow and can move the snow to the snow pile. In addition, the snow pusher can be raised and lowered by winding the rope by operating the winch.
That is, ascending force is applied to the snow pushing plate via two pulleys by winding the rope, and the frame is pivotally supported by the frame holder. It rotates and moves upward while changing its inclination angle with respect to the ground.
Also, the inner arm can be slid by pulling out the pin of the outer arm, so select one of the pin holding holes drilled in this inner arm and insert the pin to match the hole of the outer arm By doing so, the total arm length is changed, and the angle of the snow pushing plate with respect to the frame can be changed.
From the above, in the present invention, the following work related to snow removal can be performed.
1. Snow pushing work Snow is moved forward by truck running with the snow pushing plate almost perpendicular to the ground.
2. Snow scooping work The arm length is shortened so that the snow pushing plate faces obliquely upward, the snow pushing plate is pushed into the accumulated snow, and then the snow pushing plate and the snow inside thereof are lifted upward by a winch operation.
3. Snow piling work After the snow rake work described in the second item, the snow can be dropped by moving the truck and lowering the snow pushing plate at an arbitrary place. It is also possible to remove snow at a high position by changing the arm.
4). Snow attracting work The snow pushing plate is positioned near the ground as in the first term, and the snow is moved backward by moving the snow backward by moving the snow pushing plate in front of the snow.

This is especially useful for moving snow that has accumulated in the corners of a square place. In other words, since the truck cannot move at right angles, it moves in an arc shape, but this does not move the snow at the corners. So, lift the snow pusher a little, move it to the desired position, lower the snow pusher to the vicinity of the ground, perform the above-mentioned snow pulling, move this snow into the snow pusher by the snow skiing work, Snow can be moved to any location by movement.
Although the present invention has been described above, the present invention can be used by being mounted on a vehicle such as a truck, and has the feature that it can be attached and detached. Conventionally, as described above, since it is a single snow remover, it cannot be diverted for use, and when it is not in use, a suitable storage location is required. However, in the present invention, it can be removed and used as a truck, and can be attached and used as a snow removal device. Furthermore, since the snow pushing plate can be raised and lowered and its angle can be changed, the various snow removal operations described above can be performed.
It should be noted that the general traveling of the truck can be performed with the winch and the frame remaining as they are at the time of removal. In this example, the movement and position setting of the inner arm with respect to the outer arm is a manual method, but operation from the driver's seat is also possible by using a hydraulic device such as a hydraulic cylinder for the arm. In addition, the movable range of the snow pushing plate can be expanded by increasing the length of the frame or arm.
In the present invention, the second pulley is positioned above the roof of the truck, and can sufficiently cope with the change in the frame length. A power cord (not shown) is connected to the electric winch and can be operated from the driver's seat. Further, split pins or the like are appropriately used for the shafts of the respective shaft support portions, so that the shafts are prevented from falling off.
As described above, a lifting mechanism for a snow removal device useful in the present invention and a snow removal device using the mechanism can be obtained.
