Abstract

PROBLEM TO BE SOLVED: To provide a snow remover capable of surely scraping and blowing snow with a safe and simple configuration even when the snow has a high water content.SOLUTION: A snow remover is provided with a rotation body 3 which is driven by a motor 2, a driving section, and rotates around a horizontal axis to remove snow. The rotation body 3 rotates in a direction from up to down at a front side of the snow remover. The snow remover also has a hood 20 to guide snow scraped by the rotation body 3 upward from behind the rotation body 3 along a rotation of the rotation body 3. The rotation body 3 is provided with a brush 50 arranged on an outer circumference of the rotation body 3 in a spiral manner around the axis thereof.

Description

  The present invention relates to a snow remover that removes snow by rotating a rotating body.

  Conventionally, as this type of snow remover, as in Patent Documents 1 to 3 below, the auger having a pair of left and right spiral blades is rotated to collect snow in the center in the width direction, and the collected snow is collected in the auger. A structure in which the blower located on the rear side discharges upward from the chute is known. This auger type snow remover is suitable for removing snow which has a lot of moisture because it can cut snow by the rotation of a hard blade.

  However, in addition to an auger for collecting snow, a blower for flying the collected snow is also required, so that the apparatus becomes large and complicated. Moreover, since it is a structure which rotates a hard blade, it is necessary to perform an operation | work with sufficient care not to get hurt.

  On the other hand, there is a snow removal machine using a rotating brush instead of using an auger as in Patent Document 4 below. In the rotating brush, the wire is radially planted on the entire rotating shaft, and in the snow remover using the rotating brush, the snow is moved backward on the outer peripheral surface of the rotating brush constituted by a set of tip portions of the wire. In the same manner as the auger type, it is blown upward by a blower and a chute. However, in the case of heavy or hard snow with a lot of moisture, a rotating brush with a wire rod arranged radially can not scrape the snow firmly because the outer peripheral surface of the rotating brush slides on the surface of the snow. In particular, when a relatively small snowplow used in a general household is assumed, it is difficult to scrape off snow firmly because the output is small. In addition, since the structure is such that snow is blown by a blower and a chute as in the auger type, the apparatus becomes complicated and large.

  Therefore, the present invention has been made in view of the above-mentioned conventional problems, and an object thereof is to provide a snow removal machine that has a safe and simple structure, and can firmly scrape and fly even snow with a lot of moisture.

  The present invention has been made to solve the above-described problems, and a snow remover according to the present invention is a snow remover provided with a rotating body that is driven by a drive unit and rotates around a horizontal axis to remove snow. The rotating direction of the rotating body is the direction from the top to the bottom on the front side, and a hood is provided for guiding the snow scraped by the rotating body from the rear to the top along the rotation of the rotating body. A brush is arranged on the outer peripheral surface of the rotating body so as to draw a spiral around the axis.

  In the snow remover having such a configuration, the rotating body that rotates around the horizontal axis scrapes off the snow from the top to the bottom. At that time, since the brush is spirally disposed on the outer peripheral surface of the rotating body, the brush sequentially catches and scrapes off the snow. The sequentially scraped snow is sent from the lower side of the rotating body to the upper side through the rear by the rotation of the brush and the hood, but at the same time, it is also drawn in the axial direction of the rotating body. The snow sent upward while being moved in the axial direction by the rotation of the brush is vigorously blown forward by the centrifugal force and the elasticity of the brush. Further, since the brushes are arranged in a spiral shape, for example, compared with a case where the brushes are arranged in a straight line in the axial direction, the load fluctuation of the drive unit accompanying the rotation of the rotating body during snow removal is reduced, and the drive unit The driving force can be used efficiently.

  In particular, the brushes are preferably arranged in a plurality of rows at intervals in the circumferential direction. Although only one row of brushes may be arranged, snow removal can be efficiently performed by arranging a plurality of brushes at intervals in the circumferential direction.

  In that case, it is preferable that the brushes are arranged in two rows facing each other by 180 degrees. Increasing the number of brush rows increases snow removal efficiency, but increases the load on the drive unit. Therefore, it is preferable to arrange two rows of brushes facing each other by 180 degrees from the viewpoint of downsizing the drive unit and the snowplow and snow removal efficiency.

  Moreover, it is preferable that the brush is arrange | positioned in the substantially full length of the rotary body so that snow may go to the other end side from the one end side of a rotary body. You can arrange the brushes symmetrically in the axial direction so that the snow goes to the center or vice versa, but the brush rotates so that the snow goes from one end of the rotating body to the other end. By disposing it at substantially the entire length of the body, snow can be blown to the right or left side of the snow removal machine, and efficient snow removal work can be performed.

  In that case, it is particularly preferable that the spiral arrangement of the brushes is substantially rotated about the axis of the rotating body, and snow can be smoothly moved from one end side to the other end side to fly away.

  Furthermore, it is preferable that a guide guide wall is provided on the upper inner surface of the hood to guide the snow sent upward along the rotation of the rotator to the other side obliquely forward of the other end of the rotator. Since the snow is blown away while being moved toward the other end by the brush, the snow can be surely blown obliquely forward by providing the guide guide wall on the upper inner surface of the hood.

  Moreover, the guide guide wall is preferably formed separately from the hood and attached to the hood so that the direction of the guide can be adjusted. The snow throwing angle can be adjusted according to the amount of snow, the speed of snow removal or the location of snow removal work.

  On the other hand, the brush is preferably configured to be replaceable. The ability to remove snow can be restored by replacing the brush when it is worn.

  Moreover, it is preferable that a drive part is an outer rotor type motor, and the outer rotor is comprised as a rotary body, and an apparatus can be made compact.

  Moreover, it is preferable that it is comprised so that the rotation speed of a rotary body can be adjusted to 500 rpm-2000 rpm at the time of no load. Snow removal work can be efficiently performed by setting the rotation speed within this range, and the distance over which snow is blown can be changed by changing the rotation speed. If the rotational speed is less than 500 rpm, it will be difficult to sweep away snow even if it can scrape off snow. Further, when the rotational speed exceeds 2000 rpm, the rotational speed is excessively increased with respect to the speed at which the snowplow advances, and waste is increased, particularly in a walking type (hand-held type) snowplow. Therefore, the snow removal work can be performed efficiently by setting the rotation speed in the range of 500 rpm to 2000 rpm. If the rotational speed is set to a low speed, it can be used for removing fallen leaves, and if it is set to a high speed, it can be used for mowing work.

  As described above, in the snow remover according to the present invention, the spiral brush collects the snow while gradually scraping the snow while utilizing the elasticity to fly the snow forward. Snow can be removed reliably. Further, since the brush is not a hard-blade auger, it is possible to perform snow removal safely, and further, the blower and chute are not required, and the apparatus can be simplified.

  Hereinafter, a snowplow according to an embodiment of the present invention will be described with reference to FIGS. As shown in FIGS. 1 to 3, the snow removal machine in the present embodiment removes snow by rotating and driving a rotating body 3 located at the front by a motor 2 as a drive unit attached to a base 1. A small electric snow blower suitable for home use. Specifically, the motor 2 is attached to one side of the upper surface of the base 1 in the left-right direction (width direction), in the present embodiment, on the right side when viewed from the front (from the front). The motor 2 is a DC motor, in particular, an inner rotor type DC motor, and is based on the axis of the motor 2 being positioned in the left-right direction, more specifically, the drive shaft of the motor 2 being positioned on the right side. It is attached to the base 1. On the left side of the motor 2, a battery 4 for supplying power to the motor 2 and a control box 5 (control unit) for driving and controlling the motor 2 are similarly attached to the upper surface of the base 1. A cover 6 indicated by a two-dot chain line is detachably attached to the base 1 so as to cover the motor 2, the battery 4, and the control box 5 collectively from above. The battery 4 can be charged by a power cord (not shown).

  A sled 7 and a caster 8 are attached to the lower surface of the base 1 and can be moved by the sled 7 on the snow, and can be moved by the caster 8 when there is no snow. Further, a handle 9 is provided at the rear portion of the base 1 so as to extend obliquely upward from the base 1, and the operator performs a snow removal work by pushing the handle 9 and moving the snow removal machine. That is, the snowplow of this embodiment is not a self-propelled type but a hand-push type. The handle 9 is of a so-called unicycle type having a pair of rod-like bodies 90 extending from the left and right sides of the rear portion of the base 1 and can be adjusted in height. The upper part of the both rod-shaped body 90 is bent diagonally from the upper side to the lower side, and when viewed from the upper side, it opens rearward in a C shape. The upper part is a gripping part 90a, and the gripping part 90a is gripped and operated with both hands. In addition, both grips 90a are provided with start switches (not shown) that are electrical switches, and the motor 2 is started by turning on the left and right start switches with both hands. Further, the operation box 10 is attached to a position above the both rod-shaped bodies 90 so as to bridge the both rod-shaped bodies 90 left and right. The operation box 10 is attached so as to protrude forward from the rod-shaped body 90, and the upper surface thereof is an operation panel 11. The operation panel 11 is provided with a battery remaining amount lamp 12 indicating the remaining amount of the battery 4, a charging switch 13, a power switch 14, and a work light switch 15 when the battery 4 is charged. Although the work lamp is not shown, it is provided on the front surface of the operation box 10, for example. Further, it is possible to adjust the number of rotations of the rotating body 3, and an operation unit for adjusting the number of rotations is also provided on the operation panel 11. Specifically, a rotation speed changeover switch 16 for switching the rotation speed of the rotating body 3 to a plurality of stages (for example, high speed, medium speed, and low speed) is provided as an operation section for adjusting the rotation speed. A signal is sent from the switch 16 to the control box 5 to control the rotational speed of the motor 2. The rotational speed of the rotator 3 can be set to 500 rpm at a low speed, 1000 rpm at a medium speed, and 2000 rpm at a high speed, for example, in the case of three-stage switching between a high speed, a medium speed and a low speed when no snow is removed. Note that an adjustment dial or the like that can linearly adjust the rotation speed may be provided as the rotation speed adjustment operation unit.

  On the other hand, on the front side of the base 1, there are provided a rotating body 3 that rotates around a horizontal axis, and a hood 20 that opens forward so as to cover the rotating body 3 from the rear side. The axis of the rotator 3 is the left-right direction, and as shown by the arrow P in FIG. That is, the rotating body 3 rotates in a direction to scrape off snow instead of scraping it up. A timing belt (not shown) is used as a transmission means for transmitting the driving force of the motor 2 to the rotating body 3, and is interposed between the pulley 17 of the driving shaft of the motor 2 and the pulley 18 of the rotating shaft 30 of the rotating body 3. It is being handed over. The timing belt is covered with a belt cover 60. In FIGS. 1 and 3, reference numeral 19 denotes a tensioner for adjusting the tension of the timing belt.

  The rotating body 3 is rotatably supported by the left and right side walls 21 and 22 of the hood 20. Specifically, as shown in FIGS. 4 and 5, the rotator 3 rotates through a cylindrical body 31 that is hollow and the body 31 through the body 31. The rotary shaft 30 is supported by the left and right side walls 21 and 22 of the hood 20 via bearings 23. Both end portions of the rotating shaft 30 protrude outward from the left and right side walls 21 and 22 of the hood 20, and the pulley 18 is attached to the right end portion with screws to rotate integrally with the rotating shaft 30.

  A brush 50 is arranged on the outer peripheral surface of the rotating body 3 so as to draw a spiral around the axis of the rotating body 3. Specifically, the brush 50 is attached to the outer peripheral surface of the body portion 31 of the rotating body 3 continuously in a band shape having a predetermined width. The wire material 52 (see FIG. 7) of the brush 50 is preferably a synthetic resin such as nylon, and a plurality of the wire materials 52 are arranged in a band shape having a predetermined width. The width of the brush 50 and the length from the outer peripheral surface of the body portion 31 are arbitrary. For example, the width is 5 mm to 30 mm, the length is 30 mm to 100 mm, and the wire diameter of the wire 52 is, for example, 0.5 mm to The one with a thickness of 1.5 mm is suitable, and an appropriate stiffness and elasticity can be obtained and the snow scraping power and the snow throwing distance are excellent. In the present embodiment, the wire 52 has a wire diameter of 1.0 mm, a length of 80 mm, and a width of 10 mm. The belt-like brush 50 is arranged in a spiral shape and is continuous over substantially the entire length from one end to the other end of the body portion 31, and the axis of the rotating body 3 between the one end and the other end. It arrange | positions so that a circumference may be rotated about 1 time. The direction of the spiral is counterclockwise when the rotator 3 is viewed in the axial direction, and as described above, the rotator 3 rotates in the direction of the arrow P, so that snow is removed from the left side in the axial direction of the rotator 3. The direction is to the right. A pair of the spiral brushes 50 are arranged at intervals in the circumferential direction on the body 31 of the rotating body 3, specifically, two rows facing each other by 180 degrees.

  Here, the manufacturing method of the brush 50 and the mounting method to the rotating body 3 will be described. In the present embodiment, the belt-like brush 50 is first manufactured, and then the belt-like brush 50 is attached to the outer periphery of the body portion 31 of the rotating body 3. It is attached to the surface (surface). Specifically, a wire 52 having a predetermined length is arranged in the width direction of the fixed plate 51 on a metal band-shaped fixed plate 51 having a predetermined width. That is, the wire rods 52 are arranged in parallel on the fixed plate 51 so as to be orthogonal to the longitudinal direction of the fixed plate 51. In addition, the wire rods 52 are not arranged one by one, but a plurality of, more specifically five, wires are stacked on the fixed plate 51 as shown in FIG. . Then, the center line C of the fixing plate 51 is used as a folding line so that the core rod 53 is sandwiched between the wire materials 52, and the wire material 52 and the fixing plate 51 are folded in two upwards as indicated by the arrows in FIG. A bundle of wire rods 52 folded in half is sandwiched and fixed by a U-shaped fixing plate 51. By inserting the core rod 53 in this way, the wire 52 can be firmly fixed by the fixing plate 51, and the removal thereof can be prevented. Note that the holding of the wire 52 by the fixing plate 51 is performed by caulking the fixing plate 51, for example. In this way, the brush 50 having a predetermined width W (see FIG. 7) is formed. Since five brushes are stacked on the fixing plate 51, a total of ten wire rods 52 are obtained by folding in half. If the wire diameter of the wire 52 is 1.0 mm, for example, the width W of the brush 50 is about 10 mm. The fixing plate 51 is fixed to the outer peripheral surface of the body 31 of the rotating body 3 by welding or the like.

  The length of the rotating body 3 is 500 mm, for example, and the space between the side walls 21 and 22 of the hood 20 is slightly wider than that, so the snow removal width, which is the width that can be removed, is 550 mm. The snow removal width is preferably 500 mm to 600 mm, and a width that allows an adult to pass through by removing snow can be secured.

  Next, the hood 20 will be described. The hood 20 is for guiding the snow scraped off by the rotating body 3 from the rear to the upper side of the rotating body 3 along the rotation of the rotating body 3. A pair of left and right side walls 21, 22 that covers both sides, and a main wall 24 that connects both side walls 21, 22 and covers the rotating body 3 mainly from the rear side to the upper side. Both side walls 21 and 22 are in a parallel relationship with each other, and an upper front side portion thereof is cut obliquely. As shown in FIGS. 1 and 3, the main wall 24 is formed in an arc shape along the locus of the brush 50 of the rotating body 3 at the rear of the rotating body 3, and the upper part thereof is obliquely upward toward the front. The upper end portion 24 a is inclined and is located substantially immediately above the rotating shaft 30 of the rotating body 3.

  Further, as shown in FIG. 4, an L-shaped guide 25 is detachably attached to the upper inner surface of the main wall 24 by screws (not shown). The L-shaped guide 25 is formed in an L shape in a cross-sectional view from a mounting plate portion 25a to the main wall 24 of the hood 20 and a guide wall portion 25b bent at a right angle from a side end of the mounting plate portion 25a. The mounting plate portion 25a overlaps the lower side of the main wall 24, and the guide wall portion 25b is located at the right end of the mounting plate portion 25a and extends downward. A plurality (three) of the L-shaped guides 25 are attached at intervals in the axial direction of the rotating body 3, and are inclined obliquely rightward and forward as a whole, and the upper end portion thereof extends from the main wall 24 of the hood 20. It protrudes by a predetermined amount. When snow hits the guide wall portion 25b of the L-shaped guide 25, the snow is guided to the right forward (oblique front left when viewed from the rear side of the operator, that is, the snowplow). In other words, the guide wall portion 25 b of the L-shaped guide 25 is configured as a guide guide wall that guides the snow that has been sent upward along the rotation of the rotating body 3 to the right front side of the rotating body 3. Further, a pair of arc-shaped elongated holes 26 are formed in the mounting plate portion 25a of the L-shaped guide 25, and the L-shaped guide 25 can be adjusted to the left and right by loosening screws (not shown). The direction in which snow is guided (snow throwing angle) can be adjusted.

  The method of using the snowplow constructed as described above will be described. First, the power switch 14 is turned ON, the work light switch 15 is turned ON, the rotation speed changeover switch 16 is operated to set the rotation speed, and then the handle The two gripping portions 90a are gripped by both hands, both the start switches are turned on, the motor 2 and the rotating body 3 are rotated, and the snow remover is moved while pushing the handle 9 forward to perform snow removal work. As the rotating body 3 located at the front of the snowplow rotates, the spirally arranged brush 50 also rotates to gradually scrape off the snow. The scraped snow is sent from the left to the right while being sent upward from the rear, and is blown diagonally forward from the upper end of the hood 20 by the centrifugal force and the elastic restoring force of the brush 50.

  As described above, the upper portion of the hood 20 is directed forward and the brush 50 is bent, so that the snow can be blown forward vigorously. Further, since the brush 50 is in a strip shape and is arranged in a spiral shape, even the flexible brush 50 can surely scrape off snow with a lot of moisture, and is collected in one of the axial directions. You can throw snow. In particular, since the L-shaped guide 25 is attached to the hood 20, it is possible to effectively guide the snow diagonally forward and suppress the scattering of snow. Further, since the brush 50 has a spiral shape, the fluctuation of the load on the motor 2 is small as compared with, for example, an arrangement along the axial direction, and sufficient snow removal capability is ensured even with the motor 2 having a relatively small output. can do. In particular, since the spiral arrangement is substantially one rotation, the rotation during snow removal is smooth, and the snow feeding operation in the axial direction is also smooth. Further, since the brushes 50 are arranged in two rows facing each other by 180 degrees, the snow removal capability can be improved as compared with the case where the brushes 50 are arranged in a single row, and the load on the motor 2 can be reduced.

  Furthermore, the brush 50 is not a hard blade but is made of a particularly flexible synthetic resin, so even if you put your hands or feet in the hood 20, there is little possibility of serious injury and safety. Also excellent in properties.

  Further, by adjusting the angle of the L-shaped guide 25, it is also possible to adjust the snow throwing angle according to the amount of snow accumulation, the snow removal speed or the location of the snow removal work. In addition, since the rotational speed of the rotating body 3 can be switched between high speed, medium speed, and low speed, the rotational speed can be switched according to the quality of snow, the amount of snow accumulation, the snow removal location, the required snow throwing distance, and the like. . If the rotating body 3 is made low speed, it can be used for cleaning work such as collecting fallen leaves when there is no snow, and if the rotating body 3 is made high speed, it can also be used for mowing work.

  In addition, if the length of the brush 50 is shortened, stiffness will become strong and especially scraping ability will improve. When the length of the brush 50 is shortened, for example, the short brush 50 can be disposed on the body 31 having the same diameter as that shown in FIG. 4, but the diameter of the body 31 is increased as shown in FIG. The locus circle at the tip of 50 can be made the same as in FIG. For example, when the length of the brush 50 shown in FIG. 4 is 80 mm, the length of the brush 50 is 50 mm in FIG. If the diameter of the trunk portion 31 is increased as shown in FIG. 8, only the rotating body 3 needs to be changed, and no change on the side of the snowplow body is required. Further, if two or more types of rotating bodies 3 are prepared on the user side, the rotating bodies 3 can be selected and attached according to the snow condition or the like.

  Further, when it is desired to project snow on the left side when the snowplow is viewed from the front side, the spiral direction of the brush 50 may be reversed, and two types of rotating bodies 3 having different spiral directions are prepared. They can also be used as appropriate. In that case, the direction of the L-shaped guide 25 may be adjusted.

  Furthermore, there are various methods for replacement when the brush 50 is worn or deteriorated with time. That is, the rotating body 3 including the rotating shaft 30 may be integrally separated from the hood 20 and the entire rotating body 3 may be replaced at once, but the body 31 of the rotating body 3 is separated from the rotating shaft 30. As a possible structure, the rotating shaft 30 may remain in the hood 20 and be replaced by removing only the body 31. Thus, when only the trunk | drum 31 is removed and replaced | exchanged, the side wall 21 of the food | hood 20 of that side is made into the main wall 24 so that the trunk | drum 31 can be inserted / removed from the edge part of the side which does not have the pulley 18 of the rotating shaft 30. If it is configured to be detachable, the body 31 can be easily removed by removing the side wall 21. Moreover, you may enable it to replace | exchange only the brush 50, without removing the trunk | drum 31. FIG. For example, as shown in FIG. 9, when a spiral groove 32 is formed in the body portion 31 and a belt-like brush 50 is inserted into the groove 32 and attached, the belt-like brush 50 is attached from the end opening of the groove 32. It can be exchanged by inserting and removing along its longitudinal direction. If the spiral groove 32 formed in the body portion 31 has a so-called dovetail shape that has a cross-sectional shape that widens toward the bottom as shown in FIG. 9, additional fixing means for fixing the brush 50 is provided. It becomes unnecessary and can be easily replaced. In that case, the fixing plate 51 located at the base end portion of the brush 50 is also shaped to match the dovetail shape to prevent it from coming out radially outward. Still further, the brush 50 may be divided into a plurality of parts instead of a continuous belt, and the divided brushes 50 may be detachably attached to the body portion 31. For example, as shown in FIG. 10, a brush 50 may be implanted in a thin mounting plate 33, and the mounting plate 33 may be attached to the outer peripheral surface of the body portion 31 with a screw. The shape of the mounting plate 33 may be rectangular, oval or circular, and the planar shape of the implanted brush 50 is not limited to a rectangle but may be various shapes such as an oval and a circle. . Furthermore, when the mounting plate 33 is formed in a rectangular shape in plan view as shown in FIG. 10, for example, its longitudinal direction may be along the spiral direction, but it is along the axial direction of the rotating body 3 as shown in FIG. You may do it. In any case, the brush 50 may be arranged on the outer peripheral surface of the rotating body 3 so as to draw a spiral as a whole.

  In the above-described embodiment, the configuration using the inner rotor type motor 2 as the drive unit has been described. However, an outer rotor type motor may be used. That is, an outer rotor type motor is arranged at the front, and the outer rotor is configured as the rotating body 3. In that case, the outer peripheral surface of the outer rotor may be used as the outer peripheral surface of the rotating body 3, and the brush 50 may be directly disposed there. However, a separate cylindrical body is mounted on the outer peripheral side of the outer rotor, and the outer periphery of the cylindrical body is mounted. The brush 50 may be disposed on the surface. When a separate cylindrical body is mounted, the outer rotor and the cylindrical body constitute the rotating body 3. However, when the brush 50 is arranged on the cylindrical body, the configuration is such that the brush 50 is arranged directly on the outer rotor. Thus, the arrangement of the brush 50 is facilitated. Moreover, if the cylindrical body is detachably attached to the outer peripheral side of the outer rotor with screws or the like, the brush 50 can be easily replaced. In any case, by using the outer rotor as the rotating body 3 using an outer rotor type motor, the snowplow becomes compact and the number of parts is greatly reduced.

  Various arrangements are possible for the spiral arrangement of the brush 50. That is, the brush 50 may not be continuous in the spiral direction but may be discontinuous. For example, there may be a portion in which the brush 50 is partially missing, and the dot-like brush 50 having a short length in the spiral direction is formed like a broken line or an alternate long and short dash line while being spaced apart in the spiral direction. You may arrange. Furthermore, the island-like brushes 50 may be similarly arranged with a space in the spiral direction, for example, as shown in FIG.

  Furthermore, as described above, the brushes 50 may be arranged in three or more rows instead of being arranged in two rows facing each other by 180 degrees, or only one row may be arranged. Moreover, although the brush 50 was arrange | positioned over the substantially whole length of the axial direction of the rotary body 3, you may arrange | position from the middle part of an axial direction, and may arrange | position partially. Furthermore, although the spiral arrangement is substantially one rotation, it may be more than one rotation, or may be 3/4 rotation or half rotation.

  Furthermore, although the motor 2 is used as the drive unit, an engine can be used. However, the use of the motor 2 has advantages that noise and vibration are small, carbon dioxide is not discharged, and control is easy.
