Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application This invention relates to a snow removal vehicle with a dozer that removes snow while scraping it up with a dozer.

(b) Conventional technology In recent years, a dozer-equipped snow removal truck has been developed, which is a walk-behind vehicle with a self-propelled device equipped with a cargo box and a dozer, for the purpose of removing snow from residential roads in ordinary households and transporting the snow. There is.

(c) Problems to be solved by the invention By the way, when removing snow with a dozer, it is extremely difficult to set how far the dozer blade should cut into the snow, especially for this type of snow removal truck. Since the machine is small and has low horsepower, if this setting is incorrect, the engine may stall and the machine will not work properly. Furthermore, if a vehicle suddenly lifts up from the ground, the vehicle may directly receive the reaction force, causing it to overturn or be destroyed.

(d) Means for Solving the Problems Therefore, the present invention provides an arrangement in which an arm for mounting a dozer is rotatably mounted around a horizontal axis, a rod is pivotally attached to this arm, and the rod is pushed up and down. In a snow removal vehicle with a dozer that raises and lowers the dozer, a spring is interposed between the rod and the arm, and the downward pressing force of the rod is transmitted to the arm via the spring, thereby solving the above problems. This solved the problem.

(e) Effect As a result, the dozer's cutting is done through the elastic force of the spring, which corresponds to the resistance force of the snow, and even if a sudden reaction force is generated from the ground, this The spring acts as a good buffer and absorbs the shock.

(f) Example Embodiments of the present invention will be described below with reference to the drawings.

Figure 1 is a side view of the main parts showing the lifting and lowering of the dozer, Figure 2 is a plan view of the main parts showing the latch of the lifting lever, Figures 3 and 4 are side views and plan views of the entire snow removal vehicle, and Figure 5 The figure is a plan view of the main parts showing how the dozer is installed.

FIG. 6 is a cross-sectional view showing the shape of the packing box.

First, to explain the outline of the snow removal truck, a crawler-type traveling device 4, which has a crawler belt 3 hooked around a driving wheel 1 and a passive wheel 2, is driven by a driving device 7 consisting of an engine 5, a minshin 6, etc. The vehicle travels while being controlled by a control device 9 consisting of a handle 8 and the like. A cargo box 10 is placed above the traveling device 4.

Furthermore, a dozer 11 for snow removal is attached to the front part (see FIGS. 3 and 4).

By the way, the dozer 11 is configured as follows. That is, the horizontal shaft 13 is installed at an appropriate position on both the track frames 12 and the like constituting the traveling device 4,
An arm 14 is rotatably attached to this, and the above-mentioned dozer 11 is attached to the tip of this arm 14. Regarding the attachment of the arm 14 and the dozer 11, a mounting piece 15 is attached to the tip of the arm 14 with a pin 16, a bracket 17 is extended from the mounting piece 15, and the dozer 11 is attached to the bracket 17. Board 11
(A) by applying the support pin 1 to the lower part of the bracket 17 and the mounting bolt 19 to the upper part. therefore.

In this case, by making the mounting hole 20 of the mounting plate 11a on the dozer 11 side into a long hole centered on the support pin 18, the dozer 1
1 (see FIG. 1 above).

Further, by inserting an adjustable intervening rod 21 between the mounting piece 15 and the arm 14, the angle angle of the dozer 11 can be adjusted as well. At this time, if a plurality of pin holes 22 are provided between the arm 14 and the mounting piece 15 in the left and right direction, when the angle angle is increased, the amount of bias of the dozer 11 will be increased, and the distance from the travel trajectory of the crawler track 3 will be increased. It is also possible to prevent the situation where it comes off (see Figure 5 above). Others, dozer 1
1 is provided with a sled 23 for grounding, and this sled 23 can also be moved up and down with respect to its holding member 24, so the height of the sled 23 itself can be adjusted (see Fig. 1). reference).

Next, a rod 26 is interposed between the arm 14 on one side of the dozer 2 and a dozer operating lever (hereinafter referred to as lever) 25 provided on the handle 8, and the dozer 11 is raised and lowered by pushing and pulling the lever 25. That is, in this case as well, a bracket 27 is pivotally connected to the arm 14 with a pin 28, the lower end of the rod 26 is slidably fitted to the bracket 27, and the upper end is pivotally connected to the lever 25 with the same pin 29. . and.

If the bracket 27 and the rod 26 are made to repel each other by a spring 30, the downward pressing force (cutting force into the snow) of the dozer 11 will be performed by the elastic force of this spring 30 (see Fig. 1). ). The pressing force is adjusted by the operating amount of the lever 25, and in order to set it appropriately, a holding groove 32 of an appropriate level is provided in the guiding latch 31 (see FIG. 2). By doing so, so-called two-step cutting operation becomes possible. On the other hand, in these configurations, the connection point between the dozer 11 and the arm 14 is located as low as possible.

Further, the horizontal axis 13 of the arm 14 is also connected to the trunk frame 12.
By installing the dozer 11 at a relatively low position, the line of action on the arm 14 is made as low as possible and as close to the horizontal as possible, thereby preventing the dozer 11 from digging into the ground.

In addition, the packing box 10 is also configured as follows. That is, the frame 33 (two left and right pieces are provided) having a flat portion on the traveling device 4 is connected to the shaft 3 of the driven wheel 2.
4 etc., and the cargo box 10 is attached to the frame 33 so as to be tiltable in the left and right direction. In this specific example, one frame 33 simply has a cargo box 1.
0 (provide appropriate locks as necessary), brackets 35 and 36 are respectively attached to the other frame 33 and the packing box 10, and both brackets 3
It is conceivable that the 5.36 is pivoted by the bottle 37 (6th
(see figure).

As a result, when the frame 33 is tilted forward, the cargo box 10 rolls forward, and when the frame 33 is tilted to the side (naturally, to the side where the rod 26 is not present), the cargo box 10 rolls cartwheel, which is convenient for loading and unloading cargo.

In addition, since the dozer 11 and the like are naturally removable in the case of 5 or more, if it is removed and used exclusively for a transport vehicle, it can be used even in the summer when there is no snow, and its efficient use can be achieved.

(g) Effects of the invention Since this invention is as described above, that is,
In the snow removal vehicle having the structure described above, a spring 30 is interposed between the rod 26 and the arm 14, and the rod 2
6 is transmitted to the arm 14 via this spring 30, the dozer 11
The depth of cut can be set to match the resistance of the snow, and since the depth of cut can be felt while making the cut, it can be set to the optimum depth.

In addition, the upheaval of the dozer 11 from the ground due to changes in snow quality and amount of snow and the presence of obstacles is also transmitted to the body (rod 26) via the spring 30, so this can be skillfully controlled by H2N. Do not impede maneuverability and cause damage to the aircraft.
