Description

[Detailed description of the invention] The present invention relates to a snow transport device.

Traditionally, when snow removal work is carried out in snowy regions, snowpack is slid and transported using gutters in narrow spaces where trucks and other transportation vehicles cannot enter, but this method involves tilting the gutters and transporting them using gravity. Therefore, it is necessary to always maintain the slope of the gutter above a certain angle, and it cannot be used in flat places or places with uphill slopes.
There are also limits to transportation distance.

This invention has been made in view of the above-mentioned current situation, and provides a device for transporting lumps such as snowpack that can be transported efficiently with a small amount of power, regardless of the slope of the transport route or the transport distance. The purpose is to provide.

That is, this invention provides a horizontally long gutter with both ends and the top open and a smooth inner surface on a machine frame placed on the ground, and a transmission wheel is installed vertically below both ends of this gutter. A chain is wound between both transmission wheels, and the connecting pin is supported by a guide rail provided at the inner bottom of the gutter at the tension side, and the slack side is placed below the gutter. The snow transport device is characterized in that a large number of vertically oriented fins are provided at intervals on both outer sides of the chain and perpendicular to the chain and whose lower end edges are close to the inner bottom of the gutter.

An embodiment shown in the drawings will be described below.

As shown in FIGS. 1 to 4, reference numeral 1 is a machine frame installed on the ground, and on this machine frame 1, a long gutter 2 with both ends and the top open is provided horizontally.
A guide groove 3 is formed in the inner bottom of the gutter 2 along its longitudinal direction. The gutter 2 is formed by processing and molding a metal plate, hard plastic, or the like, and has a smooth inner surface. The shape of the gutter 2 can be a U-shape as shown in the second figure, or a U-shape, a V-shape, etc. as shown in FIGS. 5A and B. Below both ends of the gutter 2, a driving sprocket 4 and a driven sprocket 5, which constitute transmission wheels, respectively, are attached to a shaft 6,
It is vertically pivoted to the machine frame 1 via 7. A chain 8 is wound between the driving sprocket 4 and the driven sprocket 5, the upper or tension side portion of the chain 8 is received in the guide groove 3, and the lower or slack side portion is located below the gutter 2. A pulley 9 is provided on the shaft 6 of the drive sprocket 4, and a V-belt 11 is wound between the pulley 9 and a pulley (not shown) of a drive member 10 such as an engine. is starting to rotate.

A large number of vertical fins 12 are provided at intervals on both outer sides of the chain 8, and these fins 12 are provided in pairs so as to protrude from both sides of the chain 8 at one attachment point. It is being The lower edge of the fin 12 has a shape substantially similar to the inner bottom of the gutter 2 and is close to the inner bottom, and can take various shapes depending on the shape of the gutter 2 as shown in FIGS. 5A and 5B. 13 and 14 are guide rails of the chain 8 provided in the guide groove 3 and the machine frame 1, respectively.

In the above transportation device, when the driving sprocket 4 and the driven sprocket 5 rotate accordingly, the chain 8 has its tension side part connected to the gutter 2.
The connecting pin is supported by the guide rail 13 and moves along the guide groove 3, and the fin 12 also moves along the inner bottom of the gutter 2. Therefore, when a snowpack 15 is thrown into the gutter 2 from above the desired position of the gutter 2 as shown by the arrow A, the snowpack 15 is pushed away by the fins 12 and moves to the end of the gutter 2 as shown by the arrow B. and falls. Gutter 2 where snowpack 15 falls
The end of the groove may be located near the snow groove,
Alternatively, it may be placed on the platform of a truck or the like.

As described above, the transportation device of the present invention has snow masses 15
The snow mass 15 and the gutter 2 are
It is only necessary to apply enough force to overcome the frictional resistance between the snowpack 15 and the snowpack 15, and the snowpack 15 can be transported with a small amount of power. By the way, the maximum coefficient of friction between the snowpack 15 and the gutter 2 is approximately 0.2 or less when the gutter 2 is made of ultra-high molecular polyethylene, for example, and can be maximized by applying wax to the inner surface of the gutter 2. When smoothed, it is about 0.05, and for example, a snowpack weighing 100 kg can be transported with a very small force of 5 to 20 kg. Therefore, it is not necessary for the fins 12 to have a size corresponding to the entire cross section of the gutter 2, and it is sufficient that the fins 12 have a size that is in contact with a part of the snowpack 15.

Figures 6 to 9 show how to connect the gutter 2 when the transportation distance is long, and Figures 6 and 7 show the ends of each gutter 2 overlapped, and in this case, the connection position is between the upper and lower sprockets. A transmission member 16 that transmits the drive of
, it is only necessary to install one drive member 10. Figures 8 and 9 show one end of the gutter 2 widened,
The other end of the gutter 2 adjacent to this end is inserted.

As described above, this invention not only allows snowpack etc. to be transported regardless of the slope of the transportation route or the transportation distance, but also uses fins that focus on the fact that the coefficient of friction between the snowpack and the gutter is small. Since the snowpack is moved by pushing the snowpack, the power required for this purpose is small, and the drive transmission mechanism for this purpose has an extremely simple structure, requiring only two transmission wheels and one chain wrapped between them. It has fewer failures, can be manufactured easily and at low cost, and has the following effects.

(1) No carrier such as water is required to transport snow.

(2) It is easy to assemble the device on site, by simply assembling the finished devices or connecting the gutter and attaching a chain with fins.

(3) Transport distance and transport route can be set arbitrarily according to the situation on site.

(4) Since it is transported inside the gutter, it is easy to repair even if a snow block becomes clogged on the way.

(5) The entire system is lightweight, and the gutter can be separated, making it easy to transport the equipment.

(6) Once installed on site, snow can be loaded and transported from any position along the length of the gutter.

(7) In addition to the smooth inner surface of the gutter,
The chain with the fins attached to move the snowpack is supported by connecting pins on the guide rail installed in the gutter, so the friction between the snow and the chain and the gutter is kept to a minimum, and even heavy snowpack can be removed. It can also be moved easily.
