Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a self-propelled vehicle equipped with a loading platform with a rotor for snow removal, a chute that guides snow from the rotor to the loading platform, and a chute that guides snow from the rotor to the loading platform. The present invention relates to a snowplow equipped with a rotating body that releases snow into the chute.

[Prior Art] Conventionally, in the above-mentioned snowplow, when dumping snow to the side, the entire long chute extending from the front rotor to the rear loading platform is rotated so that the chute extends largely to the side of the vehicle body. It was composed of

[Problem that the invention attempts to solve]

However, when self-propelled vehicles are made smaller so that they can clear snow even in narrow spaces, there is a risk that the stability of the vehicle body will deteriorate in the lateral position where the chute extends significantly to the sides of the vehicle body. If there is an obstacle such as a wall or embankment on the side, there is a risk that the tip of the chute may get caught, interfering with the release work or damaging the chute.

In view of the above-mentioned circumstances, an object of the present invention is to prevent the chute from protruding to the side of the vehicle body in the side-opening position, and to enable easy and quick switching operations for this purpose.

[Means to solve the problem]

The characteristic configuration of the present invention is that, in the above-mentioned snowplow, the chute that guides snow from the snowplow rotor to the loading platform of the self-propelled vehicle is divided in its longitudinal direction, and among the divided portions of the chute, the chute on the free end side is can be freely connected and separated from the proximal end, and the link mechanism consisting of the pair of links allows the free end chute divided portion to be connected to the proximal chute divided portion in a predetermined manner. At the same time, the chute split portion on the proximal end side is installed so that it can be rotated freely between the connection position and the separation position, and the chute division part on the proximal end is installed in a lateral open position with its discharge port facing the side of the vehicle body. There is a certain thing, and its effects are as follows.

[Effect]

That is, by separating the free end portion and rotating only the proximal end portion, which has a shorter dimension in plan view, it is possible to throw snow to the side.

Moreover, in order to separate and connect the free end side portions, for example, by operating the lever 22 as shown in FIG. 2, or by operating the hydraulic cylinder 33 as shown in FIG. The free end portion 10b of the chute can be pivoted between a connection position and a separation position with respect to the proximal portion 10a of the chute. Moreover, the link mechanism 19 is
Since it consists of a pair of front and rear links 19a and 19b, the chute can be stably supported by the links and connected and separated.

[Effect of idea]

As a result, even if a self-propelled vehicle is made smaller, the chute does not extend too far to the side of the vehicle when it is released from the side, which reduces stability or causes the chute to get caught on a wall, etc. on the side of the vehicle. To provide a snowplow that can prevent such problems, and that can easily and quickly perform chute separation and chute connection operations for this purpose through a pair of front and rear links, and is excellent in terms of operability, safety, and workability in narrow spaces. Now I can do it.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

As shown in FIG. 1, a snow blower S is connected to the side of a self-propelled vehicle M equipped with a pair of left and right multi-wheeled traveling devices 1 via an arm 3 that can swing vertically using a cylinder 2. . The self-propelled vehicle M is equipped with a dump platform 5 that can be vertically oscillated by a cylinder 4, an engine 6 and a boarding operation section 7 placed on the left and right sides in front of the platform 5, and the snow blower S is equipped with a dump platform 5 that can freely swing up and down with a cylinder 4, and a driving section 7, etc. A snow removal rotor 8 that scrapes snow to the center, a snow removal plate 9 placed behind the rotor 8, a chute 10 that guides snow from the snow removal rotor 6 to a loading platform 5, and a chute 10 that releases snow from the rotor 6 into the chute 10. The snowplow is equipped with a rotary body 11 and the like to load snow on the ground onto the loading platform 5 and discharge it appropriately after being transported.
The structure is such that the snow blower S and the arm 3 can be removed to attach the dozer device, and the cylinder 2
is configured so that it can be used also for the dozer device,
It is designed to diversify the work by making it possible to perform snow removal work using a dozer device.

The chute 10 is extended above the loading platform 5, the guide 12 attached to the discharge port B at the tip is connected to the handle 15 via the rod 13 and the wire 14, and the guide 12 is moved against the spring 16 by operating the handle 15. It is constructed so that the mounting position can be changed and fixed as appropriate, and thus snow thrown into the chute 10 can be evenly loaded onto the loading platform 5.

As shown in FIGS. 1 and 2, the chute 10
The pin 18 is fitted into the support arm 17 provided at the base end 10a to removably support the free end 10b. A pair of links 19
a, 19b are pivotally connected to a stay 21 and a frame 20 protruding from the self-propelled vehicle M, respectively, and then, by operating a lever 22 that moves integrally with one link 19a, the free end 10b is connected to the frame 20. Front and rear pair of links 19
While being supported by a link mechanism 19 consisting of a and 19b, it is constructed so that it can be easily and quickly oscillated between a connected position and a separated position.
23 in the figure absorbs the difference between the locus of movement of the free end 10b when the pin 18 of the free end 10b is fitted into and removed from the support arm 17, and the locus of movement of the free end 10b by the link mechanism 19. A long hole formed for
4 is a stopper for link 19a;
The link 19a is fixed by inserting a pin 35 at the separated position of the free end 10b. As shown in FIG. 4, the proximal end portion 10a has a U-shaped cross-section, and a cover 24 that covers the opening and prevents snow from flying into the driving section 7 is removably attached. be.
The base end portion 10a is rotatably attached to the machine frame 25, and a worm 27 that engages with a gear portion 26 provided on the base end portion 10a is interlocked and connected to the handle 28 via a universal joint 29 and a rod 30. be.

That is, by operating the lever 22, the free end 10b is separated, and by operating the handle 28, the proximal end 10a, which is short in plan view, is rotated around the axis P, as shown in FIG. , is configured to be able to throw snow to the side, and is also configured to prevent the chute 10 from protruding to the side of the vehicle body in the lateral throwing position. Note that the cover 24 is removed to prevent snow from clogging inside the chute 10 when it is released to the side. A guide 31 attached to the tip of the base end portion 10a
By replacing the wire 14 with the wire 14, the guide 31 can be fixed by appropriately changing the mounting position against the spring 32 by operating the handle 15, and the angle at which the snow is thrown to the side can be changed. It is possible to adjust.

[Another example]

Next, another example will be described.

As shown in FIG. 2, the free end 1 of the chute 10
0b to the base end 10a, the hydraulic cylinder 33 is attached to the link mechanism 19, and the length of each link 19a, 19b and the pivot position to the free end 10b are adjusted appropriately. The shape and mounting structure of the chute 10 and the link mechanism 19 can be changed as appropriate, such as by omitting the elongated hole 23.

Further, the drive structure of the rotor 8 and the rotating body 11 can be changed appropriately, and the specific structure of the snowplow can be changed in various ways, such as providing a crawler traveling device instead of the multi-wheel traveling device 1.
