Abstract

PURPOSE:To improve efficiency of snow removing by providing a lift arm, hinged to a front part of a chassis and capable of swinging and rising toward a over-the-cab position, a snow bucket capable of adjusting tilt angles and a snow-compacting gripper operated by a cylinder. CONSTITUTION:A lift arm 2, hinged to a front part of a chassis 1 and capable of making upward-and-downward swing motion, is swung by operation of a hydraulic cylinder 21 and erected toward the over-the-cab position P. A snow bucket 3 hinged to the lift arm 2 is made to be capable of adjusting tilt angles. With a cutting edge 32a, provided at the edge of the snow bucket, and a snow- compacting plate 4, operated for opening and shutting by extension and contraction of a cylinder 41, collected snow S is compacted into a snow lump S1 in a cylindrical shape. Then the cylindrical snow lump S1 from the bucket 3 and the snow-compacting plate 4 is transferred to a snow chute 5 at its cab-side end. The snow lump is further transferred to a dump truck D by operation of tilting the chute rearward. Thereby rapid and safe transfer of the collected snow to a transport vehicle can be realized.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is directed to a shovel feeder for snow removal.
In detail, snow on the road is mechanically formed into a shape that is easy to load onto transport vehicles such as trucks, and is made into an overhead throw type (overhead throw type).
The present invention relates to a new type of shovel loader for snow removal that can be loaded and unloaded from the top of the cab toward the rear using an aethod, and is particularly useful for streamlining snow removal work on single-lane roads where direction changes are difficult.

(Conventional technology and technical issues to be solved) As is well known, self-propelled vehicles that remove snow from the road are equipped with a snow blower, which pushes the snow from the road to the roadside to form a snow embankment while securing a passable road surface. (snow plow) and blade (bl
ade) (e.g., snow removal trucks, bulldozers, motor graders, etc.), and vehicles equipped with snow removal equipment (e.g., snow removal trucks, bulldozers, motor graders, etc.), and vehicles equipped with snow removal equipment such as snow removal trucks, bulldozers, motor graders, etc. There is a truck loader that can scoop up snow, lift it, and put it into the bed of a dump truck. However, although the former type of snow removal is effective when targeting wide roads such as national highways and expressways, it is difficult to remove snow from streets where the width is narrow and it is not possible to form snow embankments. It is not suitable for snow removal. Snow removal from narrow roads requires at least the clear removal of snow without building snow embankments so that fire trucks can pass through without any hindrance, and usually a bell loader is used to scoop up the snow from the road and load it onto a dump truck, etc. So they have to go to a snow dump or other place to throw it away. By the way, on narrow roads in urban areas, it is impossible for shovel loaders and shovels to change direction freely. Therefore, while a dump truck is kept on standby at an intersection that intersects perpendicularly with the road targeted for snow removal, a shovel loader goes straight on the road targeted for snow removal, scoops up the snow on the road, and loads the scooped snow into packets. In extreme cases, snow removal was carried out by backing up to an intersection and dumping baguettes of snow into the bed of a waiting dump truck.
00 <; This was done in view of the above-mentioned difficulties and dangers in snow removal work using a shovel loader, and it eliminates the need to repeatedly drive the shovel loader in reverse, which is dangerous and painful, and also allows snow on the road to be transferred to the bed of a truck, etc. It is molded into a shape that is easy to load, and the cab is installed in one direction with an overhead slot (
To provide a new type snow removal shovel loader that can quickly load and unload from the top of the cab to the rear [Means adopted to solve the problem] In order to solve the above technical problem, the present inventor The adopted methods are explained below with reference to the attached drawings. That is. The present invention provides a shovel loader with an overflow opening, which includes:A. A lift arm that is pivoted to the front of the chassis 1 and swings up and down toward a cuff over position P above the cab 11 in response to the expansion and contraction of a lift cylinder 21 interposed between the chassis and the chassis. 2 F1 positive means; B. A scoop, which is a snow bucket 3, which is supported on the free end of the lift arm 2 and whose relative angle with the lift arm 2 and ground angle are adjusted by the expansion and contraction of a bucket cylinder 3l interposed between the lift arm 2 and the arm 2. Means of taking; C. A snow pack forming means, which is a snow compacting gripper 4, which is hinged near the pivot of the snow bucket 3 and opened and closed by the expansion and contraction movement of an opening/closing cylinder 41 interposed between the two snow buckets 3; It is something to do. and the above technical means A and B. In addition to C,
Furthermore, D. A gutter-like member is supported by a lever 2 at the rear of the cab 11 so as to be able to swing up and down, and one end, which serves as a snow mass receiving section, is connected to the snow compacting glyph par 4 by extending and contracting the sheave cylinder 51. The tilt snowshooter is capable of inheriting snowflakes by approaching the cap-over position P where the chute cylinder 51 should open downward, while the other end swings downward as the chute cylinder 51 is contracted, causing the snowflakes to flow out. By adding the following means for transporting snowpack, we succeeded in solving the above-mentioned technical problem. [Examples] The present invention will be described in more detail below based on examples shown in the accompanying drawings. In addition, FIG. 1 is a side view showing the state of snow removal and snowpack loading according to the first embodiment of the present invention, FIG. Figure 3 shows the same snow bucket 1.
}・A partially enlarged perspective explanatory diagram showing the opening/closing mechanism of the snow compaction gripper, FIG. 4 is a partially enlarged perspective explanatory diagram showing the tilt mechanism of the snowshooter in the first embodiment, and FIG. 5 is according to the second embodiment of the present invention. It is a side view showing the state of snow removal and snowpack loading. In the drawings, what is designated by the symbol 1 is the chassis of the shovel loader C of this embodiment, and a cab (cabal) on which a driver rides and operates is provided on the top of the chassis. What is designated by the symbol 2 is A lift arm is pivotally supported on the front part of the chassis 1 so as to be able to swing up and down via a pivot P1, and a fluid pressure cylinder (
In this embodiment, the extension of the hydraulic cylinder 2l causes the cab 11 to rise and swing toward the cab over position P above the cab 11. What is designated by the reference numeral 3 is a snow bucket that is pivotally supported at the free end of the lift arm 2 via a pivot Pt,
By expanding and contracting a fluid pressure cylinder (hydraulic cylinder) 31 interposed between the lift arm 2 and the lift arm 2, the relative angle with the lift arm 2 and the installation angle with the road surface G can be arbitrarily adjusted. In this embodiment, the snow packet 3 has a cutting edge portion 3 that digs up snow S on the road surface G.
2a, a snow scooping part 32b forming a cylindrical curved surface on which the snow S dug by the edge part 32a is scooped, and a side plate 3 surrounding both sides of the edge part 32a and the snow clearing part 32b.
It consists of 2c and 32c. The reference numeral 4 designates a snow compaction gripper which is coaxially supported with the free end of the lift arm 2 by a pivot P2 and is coaxial with the snow bucket 3, and whose upper inner surface 42a is continuous with the snow scooping part 32b of the packet 3. It has a cylindrical curved surface that can be formed into a cylinder, and has side plates 42b on both sides thereof. This snow removal plate 4 opens and closes just like opening and closing the upper and lower jaws by the expansion and contraction of an opening/closing cylinder (hydraulic cylinder) 41 connected between its own side plate 42b and the side plate 32c of the snow bucket, and is used to scoop snow. The snow S scooped onto the portion 32b is formed into a cylindrical snow mass S.
It can be formed into 1. What is indicated by the code 5 is
A U-shaped tilt switch is installed on a support P that stands behind the main body 11 in the chassis 1 so as to be able to move up and down in a scale-like manner.
He is a snow shooter. The snow shooter 5 lies approximately horizontally on the roof of the k+b 11 by the extension action of the chute cylinder 51 (hydraulic cylinder) interposed between the support column T. The cab-side end of the snowshooter 5 in this state is positioned so that it approaches the free end of the snow compaction plate 4 when the lift arm 2 rises to the cab over position P and the snow compaction plate 4 opens. Designed with packet/snow compaction plate 3
・It is possible to inherit the snowpack S1 that is formed into a cylindrical shape and transferred from 4. By reducing the chute cylinder 51, the snow shooter 5 tilts the inherited snow mass S1 backward, and the snow mass S1 is transferred and loaded onto the platform of a dump truck D waiting behind the shovel loader C. Although the apparatus of this embodiment is generally constructed as described above, the present invention is by no means limited to the above-mentioned embodiments, and various modifications can be made within the scope of the claims. Regarding the connection method of the lift arm 2, snow bucket 3, snow compaction plate 4, and snow shooter 5, it is possible to adopt a conventionally well-known connection mechanism. The specific inner shapes of the bucket 3 and the snow compacting plate 4 can also be changed in design as appropriate, taking into account the convenience of loading onto a transport vehicle. For example, as shown in FIG. Depending on the request, we will also adopt the option of shaping the snow into a semi-cylindrical shape so that it can be loaded onto dump truck D. (Effects of the present invention) As explained above with reference to the embodiments, the shovel loader manufactured by applying the present invention collects snow on the road surface into a snow bucket while moving forward, and removes it by the blocking operation of the snow compaction plate. After compression molding into a chute that matches the inner surface shape and a shape that is easy to load, and lifting it to the cap-over position and opening the bagent and snow compaction plate, the snowpack is transferred to a tilt snowshooter lying horizontally waiting. Therefore, by tilting the snowshooter backward, the snowpack can be quickly loaded onto the platform of a transport vehicle such as a dump truck waiting behind. Even on the road, snow removal and loading into transport vehicles such as trucks can be done safely and quickly without the need to drive in reverse. Since the driver does not have to change direction at right angles to load the loader, the driver's fatigue is greatly reduced, and the snow removal efficiency is dramatically improved. This can fundamentally solve the problem of snow removal on narrow roads in urban areas, which is a common drawback of this type of snow removal equipment, and is of great benefit to road managers and snow removal companies in snowy countries.
