  Next, with reference to the attached drawings, a snow remover according to a preferred embodiment of the present invention will be described in detail by taking as an example a case where it is attached to a bucket of a hydraulic loader. FIG. 1 is a perspective view of a snowplow according to a preferred embodiment of the present invention as viewed obliquely from above, and FIG. 2 is a front view of the snowplow shown in FIG.

  A snowplow according to a preferred embodiment of the present invention generally indicated by reference numeral 10 in FIG. 1 includes a snow collecting portion 12 (the direction of travel of the snowplow 10 is indicated by an arrow in FIG. 1). . The snow collecting portion 12 includes a fixed shaft 14 arranged so as to extend in a substantially vertical direction, a rotation shaft 16 attached to the fixed shaft 14 so as to rotate about an axis extending in a substantially vertical direction, and a fixture 14a. And a fixing tool 18 for fixing the snow collecting portion 12 to the bucket, and a snow collecting plate 20 attached to the rotating shaft 16 via an attachment 16a.

  The snow collecting plate 20 is attached to a rectangular plate-shaped main body 20a fixed to the rotating shaft 16, a rubber plate 20b attached to the opposite side of the fixing shaft 14 of the main body 20a, and an upper end and a lower end of the main body 20a, respectively. And baffle plates 20c and 20d. Preferably, a saw blade portion 20f for collecting snow is provided below the lower baffle plate 20d.

  The baffles 20c and 20c are for avoiding the main body 20a and / or the rubber plate 20b from damaging the wall surface of the greenhouse when collecting snow near the greenhouse, as will be described later. In addition to the circular shape, an elliptical shape or a semicircular shape (not shown) may be used. Preferably, as shown in FIG. 3A, a deflecting tire 20e is rotatably attached to the upper deflecting plate 20c via a shaft 20e1. Preferably, as shown in FIG. 3B, the outer edge of the tire 20e is positioned outside the outer edge of the rubber plate 20b so that the rubber plate 20b comes into contact with the wall surface of the greenhouse during snow removal work. Can be avoided.

  Preferably, the rubber plate 20b is detachably attached to the main body 20a. That is, as shown in FIG. 4A and FIG. 4B, the rubber plate 20b is sandwiched between the main body 20a and the mounting plate 20b1, and fixed with the bolts 20b2, thereby the main body 20a. Removably attached to. Note that the method of attaching the rubber plate 20b shown in FIGS. 4A and 4B is merely an example, and the rubber plate 20b may be detachably attached by other appropriate attachment methods.

  FIG. 5A is a cross-sectional view showing an example of the configuration of the fixed shaft 14 and the rotating shaft 16. In the configuration shown in FIG. 5A, the rotating shaft 16 is nested in the fixed shaft 14 and is provided on the upper portion of the rotating shaft 16 on the circular plate 14 b provided on the upper end of the fixed shaft 14. A circular plate 16b is placed. As shown in FIG. 5 (b), the circular plates 14b and 16b are provided with a plurality of holes 14b1 and 16b1 at corresponding positions along their peripheral edges, respectively, so that the rotary shaft 16 can be rotated at a desired angle. Then, the main body 20a and the rubber plate 20b can be selected at desired angles by inserting the bolts 17 into the holes 14b1 and 16b1.

FIG. 6 is a cross-sectional view showing another example of the configuration of the fixed shaft 14 and the rotating shaft 18. In the configuration shown in FIGS. 5A and 5B, the rotary shaft 16 is manually rotated. In the configuration shown in FIGS. 6A and 6B, a rotary shaft is used by using a cylinder. 16 is configured to mechanically rotate. In other words, the tip of the piston rod 22a of the cylinder 22 is fixed to an appropriate position of the rotary shaft 16 with the pin 16c. Then, the piston rod 22a rotates the rotating shaft 16 by extending, in the example (shown as the angle of desired body 20a and the rubber plate 20b with respect to the traveling direction of the snow removing machine 10, from the angle alpha ₁ angle alpha ₂ ) can be changed. The configuration for rotating the rotary shaft 18 shown in FIGS. 5 and 6 is exemplary, and other appropriate configurations (including a configuration using manual operation or a cylinder) may be adopted.

  Preferably, the snow remover 10 further includes a snow removal tool 24 for removing snow accumulated on the wall surface of the greenhouse. The snow removal tool 24 includes a pair of curved horizontal members 24a arranged at intervals, a vertical member 24b connecting one end of the horizontal member 24a, and a snow removal plate 24c attached to the vertical member 24b. The other end of the horizontal member 24 a is attached to the base member 26. As shown in FIG. 8 (b), the snow drop plate 24c is curved in a direction opposite to the traveling direction of the snow remover 10, thereby avoiding damage to the wall surface of the greenhouse. Three snow removers 24 are attached to the base member 26, but two or less or four or more snow removers 24 may be attached. The base member 26 is attached to the attachment member 26b via a spring 26a. By attaching the attachment member 26b directly to an appropriate position of the snow removal machine 10 via an appropriate attachment (not shown), snow removal is performed. A tool 24 is attached.

  Next, an example of the operation of the snowplow 10 configured as described above will be described. Prior to the use of the snow remover 10 of the present invention, snow removal between adjacent greenhouses (usually about 3 m between the greenhouses) is performed using an existing snow remover such as a front loader. The snow remover 10 is put into an operable state by attaching the snow remover 10 to a bucket of a hydraulic loader using a bolt or the like. First, when the angle of the snow collecting plate 20 is adjusted as desired and the hydraulic loader is operated, snow at a location adjacent to the greenhouse is collected by the snow collecting plate 20 (main body 20a and / or rubber plate 20b). The snow is removed to the desired location by the bucket. At that time, before the main body 20a and the rubber plate 20b of the snow collecting plate 20 contact the wall surface of the greenhouse, the deflecting plates 20c and 20d and the tire 20e for deflecting contact the wall surface of the greenhouse, so that the side surface of the greenhouse is damaged. There is no.

  In addition, when the snow removal tool 24 is attached to the snow collecting portion 12, snow attached to the wall surface of the greenhouse can be knocked off, so that snow removal work can be performed more efficiently. Since the snow removal tool 24 is attached via the spring 26a and the snow removal board 24c is curved in the direction opposite to the traveling direction of the snow removal machine 10, even if the snow removal tool 24 hits the wall surface of the greenhouse. Since the snow remover 24 bends satisfactorily (in FIG. 9, the solid line shows the moment when the snow remover plate 24c contacts the side of the greenhouse, and the broken line shows the snow remover 24 as the snowplow 10 advances. Is a diagram showing a bent state), there is no risk of damaging the greenhouse. In this way, by running the hydraulic loader along the greenhouse, it is possible to remove snow from adjacent locations and wall surfaces of the greenhouse without damaging the greenhouse. The snow removal operation is completed by disposing of the snow collected in a place away from the edge of the greenhouse in this manner by a conventional method (for example, removing it with a bucket such as a front loader).

  In the above embodiment, the snow remover 10 is attached to the bucket of the hydraulic loader. However, as shown in FIG. 10, the snow collecting unit 12 of the snow remover 10 is connected to the self-propelled snow remover via an appropriate attachment. And / or the snow remover 24 may be used (FIGS. 10A and 10B show a state in which the angle of the snow collecting part 12 and the snow remover 24 is changed. ), The snow collecting unit 12 and / or the snow removal tool 24 may be attached to the self-propelled farm equipment via an appropriate attachment.

  The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the invention described in the claims, and these are also included in the scope of the present invention. Needless to say, it is something.
