Description

[Detailed description of the invention] This invention relates to a rotary/soil removing plate-type snow blower that can be used for both functions by equipping the mechanism of a rotary snow blower with an earth removing plate type function.

Conventionally, small and medium-sized snow blowers have been limited to two types: a rotary set type and an earth removal plate type, and each type is used depending on the snow removal location and snow cover conditions.

In general, the amount of snow that can be removed using a snow blower is said to be around 100 blocks, and when the amount of snow is around 10,077Ell+, the shovel type is faster and more efficient in removing snow, and the amount of snow removed depends on the size of the machine. , the amount of snow removed, etc. is different, but if this is done with a rotary set, the snow removal speed will be lower due to the structure, but in heavy snow conditions, this rotary set is said to be more efficient than the earth removal plate type.

In this way, the rotary set and the earth removal plate type each have their drawbacks depending on the snow conditions, and two types of snow removal machines are required to efficiently process the snow depending on the snowfall amount, snowfall frequency, etc. be.

Therefore, a snow blower has been proposed in which the mechanism of a rotary snow blower is equipped with a soil removal plate function, so that it can be used for both purposes.

However, in conventional rotary snow blowers, even if a part of the auger is moved up and down by a handle or a hydraulic cylinder, the vertical differential distance is short, so the functionality of the soil removal plate cannot be achieved.

This idea was proposed in order to improve and eliminate the shortcomings of the conventional one, and its gist is to install a triangular single-axis rotatable endless track band around the suspension of a rotary snow blower. A cylinder is installed between the rear part of the snow blower and the main body of the snow blower, and the cylinder allows part of the auger to be moved up and down significantly, and the soil removal plate can be easily attached to the drive shaft of the endless track belt with a pin. It is an object of the present invention to provide a snow blower that is detachable and has a structure that allows each device to fully demonstrate its performance.

The details of this invention will be described below with reference to embodiments shown in the drawings.

Fig. 1 shows an embodiment of the rotary/snow removing machine according to this invention, and in this figure, reference numeral 1 indicates an undercarriage crawler 1 having a triangular single-axis rotatable endless track structure.
Reference numeral 2 denotes a main body frame on which the suspension crawler 1 is arranged on both the left and right sides.By attaching it to the drive wheel shaft 3 placed on the top of the suspension crawler 1 and mounting it at a high position, it can move up and down using the drive wheel shaft 3 as a fulcrum. It is possible to make a large difference in the distance up and down.

4 is installed between the suspension crawler 1 and the main body frame 2 by attaching the cylinder side to the rear part of the suspension crawler 1 via the holding fitting 5 and the piston side to the main body frame 2 via the holding fitting 6. A hydraulic cylinder installed in the main body frame 2 is vertically moved around the driving wheel shaft 3 of the undercarriage crawler 1 as a fulcrum by piston operation.

7 is an engine mounted on the operating section 8 at the rear of the main body frame 2, and a transmission 10 (second
Power is transmitted to the undercarriage crawlers 1 disposed on both the left and right sides of the main body frame 2 via the main body frame 2 (see figure).

11 is a main body frame 2 with a blower (not shown) installed inside.
12 is an auger casing that houses a screw-shaped auger 13;
4 is a snow-throwing chute rotatably attached to the discharge port 15 of the blower case 11; 16 is a soil removal plate;
The left and right wheels 1 have their rear ends pivoted via bearings 19 to a horizontal shaft 18 that is fixed to the drive wheel shaft 3 of 1 with a pin 17, and are also fixed to the auger casing 12 with bolts 20.
By being fixed to the front end of the pair of earth removal plate arms 21,
This soil removal plate 16 is integrally attached to the front of the auger 13.

Further, the earth removal plate 16 can be removed from the front of the auger 13 while being fixed to the front end of the earth removal plate arm 21 by removing the pins 17 and bolts 20 and pulling out the horizontal shaft 18 from the drive wheel shaft.

With the above configuration, when the amount of snow is small, the earth removal plate 16 is integrally attached to the front of the auger 13 as shown in FIG. If the vehicle is driven by the crawler 1, snow removal work can be performed using the evacuation plate 16.

In this case, since the main body frame 2 is mounted at a high position and can be moved vertically over a large distance, the function of the earth removal plate type can be fully demonstrated.

Further, the force for lowering the auger 13 and the earth removal plate 16 is only the difference obtained by subtracting the weight of the rear part from the weight of the front part using the drive wheel shaft 3 of the undercarriage crawler 1 as a fulcrum, but Since the hydraulic cylinder 4 is installed between the main body frame 2 and the hydraulic cylinder 4, by extending the hydraulic cylinder 4 and tilting the main body frame 2 forward about the drive wheel shaft 3 of the undercarriage crawler 1 as a fulcrum, the entire weight of the snow blower main body can be reduced. can be applied to the ground in front of it, canceling out the upward reaction force.

Furthermore, when there is a heavy snowfall, by removing the earth removal plate 16 from the front of the auger 13, snow removal work can be performed by the rotating action of the auger 13.

In this way, depending on the amount of snow, the snow removal plate 16 or the auger 13 can be used to remove snow, allowing for efficient snow removal with a single snow removal machine.

As explained above, this idea uses a triangular, one-axis rotatable endless track structure for the undercarriage crawler of a rotary snow blower, and these are placed on both the left and right ends to position the main body frame at a high position, and the foot The earth removal plate is attached to the tip of an arm that is removably attached to the drive wheel shaft of the undercarriage crawler with a pin, and is attached to the rear of the undercarriage crawler. The structure allows for vertical differential movement using a hydraulic cylinder installed between the rear part of the main frame and the rear part of the main body frame, making it possible to fully demonstrate the functions of both the rotary set and the earth ejecting plate type. It is extremely excellent as a snow blower that can also be used as a board.
