[0010] [Embodiment] As shown in Figure 1, a lawnmower system 100 according to this embodiment includes a lawnmower 1 and a recirculation device 70. The lawnmower 1 will be described as a rotary lawnmower, but is not limited to this. The lawnmower 1 is also a walk-behind, self-propelled working machine, but is not limited to this. The lawnmower 1 may also be a robotic working machine.

[0011] As shown in FIGS. 2 and 3 , the lawnmower 1 has a body portion (machine body (main body of the device)) 10 , a plurality of wheels 2 , a power source 4 , and a bag (storage portion) 60 .

[0012] The body portion 10 has a housing 11. The housing 11 houses a blade 50. The housing 11 has an opening 11o. The opening 11o is located at the bottom of the housing 11. A blade (cutting edge) 50 for cutting grass is provided in the opening 11o. The blade 50 is attached to the end of an output shaft 40 that rotates by the power of the power source 4. The output shaft 40 extends downward. Preferably, the output shaft 40 is arranged along the vertical direction.

[0013] The plurality of wheels 2 are rotatably attached to the body portion 10. The plurality of wheels 2 include two front wheels 241 arranged on the left and right and two rear wheels 242 arranged on the left and right. The lawnmower 1 can move by rotating the plurality of wheels 2. Note that the number of wheels 2 provided on the lawnmower 1 is not limited to four.

[0014] The power source 4 is attached, for example, to the upper part of the body portion 10. The power source 4 may include a travel motor, a work motor, etc. The travel motor is a drive unit that drives the plurality of wheels 2 to rotate. The work motor is a drive unit that drives the blade 50 to rotate. The motor shaft of the work motor is, for example, the output shaft 40 described above, but is not limited to this.

[0015] As shown in Figures 3 and 4, the housing 11 has a swivel portion 110. The center of the swivel portion 110 coincides with the axis SC of the output shaft 40. The swivel portion 110 is a space surrounded by a top plate 11a (Figure 5), an outer cylinder portion 111, and an inner cylinder portion 112 (Figure 4). The outer cylinder portion 111 is formed in a cylindrical shape. The upper end of the outer cylinder portion 111 is connected to the top plate 11a. The center of the outer cylinder portion 111 coincides with the axis SC of the output shaft 40. The inner cylinder portion 112 is formed in a cylindrical shape. The outer diameter of the inner cylinder portion 112 is smaller than the outer diameter of the outer cylinder portion 111. The upper end of the inner cylinder portion 112 is connected to the top plate 11a. The center of the inner cylinder portion 112 coincides with the axis SC of the output shaft 40.

[0016] A passage opening 113 that opens upward and rearward is provided at the rear right portion of the swivel unit 110. The passage opening 113 is connected to the discharge passage 12. The discharge passage 12 is a passage for discharging grass clippings. The discharge passage 12 is provided in the body unit 10. The grass clippings are pieces of grass cut by the blade 50. As shown in FIG. 5 , the discharge passage 12 is provided with an upstream opening 121 and a downstream opening 122. The passage opening 113 is connected to the upstream opening 121 of the discharge passage 12.

[0017] As shown in Fig. 4, the discharge passage 12 extends rearward substantially tangentially to the outer cylinder 111 of the swivel unit 110 when viewed from the top-bottom direction. As shown in Fig. 5, the discharge passage 12 extends rearward and upward when viewed from the left-right direction. A downstream opening 122 of the discharge passage 12 opens rearward.

[0018] The blade 50 rotates around the output shaft 40 in the direction of the arrow Ra. When the blade 50 rotates in the direction of the arrow Ra, the blade 50 cuts grass. Furthermore, the rotation of the blade 50 in the direction of the arrow Ra generates an airflow (swirling flow) in the direction of the arrow Rb. In FIG. 4 , the directions of the arrows Ra and Rb are counterclockwise when viewed from the bottom of the lawnmower 1. Note that the swirling portion 110 may be formed so that the direction is clockwise when viewed from the bottom of the lawnmower 1. The blade 50 is provided with wings 50A for generating an updraft. Because the wings 50A are formed on the blade 50, an updraft is generated when the blade 50 rotates.

[0019] The grass clippings cut by the blade 50 are carried by the air current. The grass clippings flow into the discharge passage 12 through the passage opening 113 of the swiveling unit 110. The grass clippings that have flowed into the discharge passage 12 flow into the bag 60 through the downstream opening 122 of the discharge passage 12. The downstream opening 122 of the discharge passage 12 may be provided with an opening adjustment mechanism that adjusts the opening degree of the downstream opening 122.

[0020] As shown in Figures 1 and 2, the bag 60 is a container for storing grass clippings. The bag 60 is made of, but is not limited to, a soft material. The bag 60 may also be made of a strong material, such as a plastic case. The bag 60 is arranged to cover the downstream opening 122 of the discharge passage 12. The bag 60 is attached to the bag attachment portion 13. The bag attachment portion 13 is provided at the downstream opening 122 of the discharge passage 12. When the bag 60 is attached to the bag attachment portion 13, the interior of the bag 60 and the discharge passage 12 are connected. The bag 60 stores the grass clippings that are carried out from the body portion 10 via the downstream opening 122 of the discharge passage 12.

[0021] The bag 60 is detachable from the bag attachment portion 13. The body portion 10 is provided with an opening cover 14. The opening cover 14 is rotatable, for example, around the upper end of the opening cover 14 as a rotation axis. When the bag 60 is detached from the bag attachment portion 13, the downstream opening 122 of the carry-out passage 12 is closed by the opening cover 14.

[0022] As shown in FIG. 1 , the bag 60 has an inlet 61, a rear end face (rear surface) 62, an upper end face (upper surface) 63A, a lower end face (lower surface) 63B, a left end face (left surface) 63C, a right end face (right surface) (not shown), and a front end face (front surface) 63D. The inlet 61 is a portion that opens toward the body portion 10. The inlet 61 is formed on the front end face 63D, but may also be formed on the lower end face 63B. The inlet 61 is connected to a downstream opening 122 of the discharge passage 12. When the bag 60 is attached to the bag attachment portion 13, the inlet 61 of the bag 60 is connected to the downstream opening 122. The rear end face 62 faces rearward in the front-to-rear direction of the bag 60. If the inlet 61 is formed on the front end face 63D, the rear end face 62 is located on the opposite side from the inlet 61. The upper end surface 63A faces upward in the up-down direction of the bag 60. The lower end surface 63B faces downward in the up-down direction of the bag 60. The left end surface 63C faces leftward in the left-right direction of the bag 60. The right side surface (not shown) faces rightward in the left-right direction of the bag 60. The front end surface 63D faces forward in the front-to-rear direction of the bag 60. The upper end surface 63A, the lower end surface 63B, the left end surface 63C, and the right side surface (not shown) extend from the inlet 61 (front end surface 63D) to the rear end surface 62. The rear end surface 62 may be substantially rectangular.

[0023] An outlet 64 through which grass clippings are discharged is formed in the rear end surface 62. The outlet 64 may be formed in the upper end surface 63A, the lower end surface 63B, the left end surface 63C, or the right end surface (not shown) instead of the rear end surface 62. Multiple outlets 64 may be formed. In this case, one outlet 64 may be formed in at least two of the rear end surface 62, the upper end surface 63A, the lower end surface 63B, the left end surface 63C, and the right end surface (not shown). Alternatively, multiple outlets 64 may be formed in the rear end surface 62, the upper end surface 63A, the lower end surface 63B, the left end surface 63C, or the right end surface (not shown). Alternatively, a combination of these may be used. The inlet 61 and the outlet 64 are spaced apart. A lid (blocking portion) 65 ( FIG. 3 ) is attached to the outlet 64. The lid 65 covers the entire outlet 64, but may also cover only a portion of it. Because the lid 65 is attached to the outlet 64, grass clippings transported from the downstream opening 122 of the discharge passage 12 are stored inside the bag 60 without being discharged from the outlet 64. The lid 65 is detachable from the outlet 64.

[0024] When the lid 65 is removed from the outlet 64, the airflow generated by the rotation of the blade 50 causes at least a portion of the grass clippings located in the bag 60 to flow out through the outlet 64. Therefore, the grass clippings can be discharged to the outside of the bag 60 without removing the bag 60. As described above, the outlet 64 is formed on the rear end surface 62 opposite the inlet 61 connected to the downstream opening 122. Therefore, the grass clippings that flow into the bag 60 through the downstream opening 122 can be efficiently discharged to the outside of the bag 60. The lid 65 may have a throttle structure that allows the opening area to be changed. In this case, the amount of grass clippings flowing out of the outlet 64 can be adjusted without removing the lid 65 from the outlet 64. Therefore, if the lid 65 has a structure that allows the opening area of ​​the outlet 64 to be changed, the lid 65 may be disposed inside the bag 60.

[0025] As shown in Figure 1, the recirculation device 70 has a duct member (flow path member) 71 and a storage section (storage device) 72. The duct member 71 is a member that passes grass clippings discharged from the outlet 64 of the bag 60. The duct member 71 is detachable from the outlet 64. The duct member 71 has one end 71A that is detachable from the outlet 64, and another end 71B opposite the one end 71A. A connection section 71C is provided at the other end 71B of the duct member 71. The connection section 71C is formed so as to be connectable to the storage section 72.

[0026] The storage section 72 is a container that can store grass clippings discharged from the duct member 71. The storage section 72 is disposed below the blade 50. The storage section 72 has an upper wall 72A, a lower wall 72B, a first side wall 72C, a second side wall 72D, a third side wall (not shown), and a fourth side wall (not shown). The storage section 72 is capable of supporting the lawnmower 1 on the upper wall 72A. In other words, the storage section 72 is formed so that the upper wall 72A can support the lawnmower 1.

[0027] The first side wall 72C is located between the upper wall 72A and the lower wall 72B. The upper end of the first side wall 72C is connected to the edge of the upper wall 72A. The lower end of the first side wall 72C is connected to the edge of the lower wall 72B. The first side wall 72C extends in a direction perpendicular to the lower wall 72B. A grass clippings inlet 73 is formed in the first side wall 72C. The connecting portion 71C of the duct member 71 can be connected to the grass clippings inlet 73.

[0028] The second side wall 72D is located between the upper wall 72A and the lower wall 72B. The upper end of the second side wall 72D is connected to the edge of the upper wall 72A. The lower end of the second side wall 72D is connected to the edge of the lower wall 72B. The second side wall 72D is located on the opposite side of the first side wall 72C. The second side wall 72D slopes upward from the lower wall 72B toward the upper wall 72A. The second side wall 72D can function as a slope 74 for moving the lawnmower 1 to the upper wall 72A. A communication opening 75 is formed in the upper wall 72A. The communication opening 75 is an opening that connects the interior of the storage section 72 to the outside of the storage section 72.

[0029] As described above, the lawnmower 1 is placed on the upper wall 72A. The lawnmower 1 is placed on the upper wall 72A so that the blade 50 is positioned above the communication opening 75. When the blade 50 rotates, the grass clippings located in the storage section 72 are raised by the airflow generated by the rotation. In this case, the grass clippings raised by the airflow flow into the housing 11 through the communication opening 75 formed at a position reached by the airflow, and are then chopped by the blade 50.

[0030] The shredded grass clippings pass through the swivel section 110 of the housing 11 and the discharge passage 12 in that order, and flow into the bag 60. The grass clippings located in the bag 60 can be transported (recirculated) from the outlet 64 through the duct member 71 to the storage section 72. The grass clippings in the storage section 72 can reach the blade 50 through the communication port 75. The lawnmower 1 rotates the blade 50 so that the recirculated grass clippings are re-cut while being recirculated to the blade 50.

[0031] In this way, a circulation path is created in which grass clippings circulate via blade 50. This allows the grass clippings stored in bag 60 to be broken down into smaller pieces, thereby increasing the amount of grass clippings that can be stored in bag 60. The circulation path includes discharge passage 12, bag 60, duct member 71, and storage section 72.

[0032] The recirculation device 70 of the lawn mowing system 100 includes a suction fan motor (promoting unit) 76 that promotes the flow of grass clippings flowing out of the outlet 64. In FIG. 1 , the suction fan motor 76 is located inside the storage unit 72, near the grass clippings inlet 73. The suction fan motor 76 sucks the grass clippings through the duct member 71, promoting the flow of the grass clippings flowing out of the outlet 64. As a result, the grass clippings are more likely to be transported (recirculated). The suction fan motor 76 may be replaced with a blower fan motor. In this case, the blower fan motor is located inside the storage unit 72, near the communication port 75. The blower fan motor blows air onto the grass clippings rising toward the communication port 75, promoting the flow of the grass clippings that flow out of the outlet 64 and are stored in the storage unit 72. As a result, the grass clippings are more likely to be transported (recirculated).

[0033] The recirculation device 70 of the lawn mowing system 100 includes an extension 78 that extends upward from the outer surface (surface of the upper wall) of the upper wall 72A. The extension 78 restricts at least a portion of the debris from flowing out of the body 10 through the opening 11o of the lawn mower 1. The debris includes sand, dust, and grass clippings. The extension 78 is formed of an elastic material such as rubber. The extension 78 abuts against the body 10, but there may be a small gap between the extension 78 and the body 10. The extension 78 is located rearward of the blade 50, but may also be located on the outer periphery of the opening 11o. The extension 78 may be detachable from the storage section 72.

[0034] The recirculation device 70 of the lawnmowing system 100 includes a mesh member (interposition member) 79 at the communication opening 75. The mesh member 79 is interposed in the communication opening 75 and has a mesh pattern. The mesh member 79 restricts the flow of grass clippings through the communication opening 75 while allowing the flow of air through the communication opening 75. While the communication opening 75 is formed in the upper wall 72A, this is not a limitation. The communication opening 75 may be formed in a location other than the upper wall 72A of the storage section 72, as long as it is in a position that can be reached by the airflow caused by the rotation of the blades 50.

[0035] As described above, according to this embodiment, a better lawnmower 1 and lawnmower system 100 are provided.

[0036] The above embodiment may be modified as follows: In the following modifications, components equivalent to those described in the above embodiment are denoted by the same reference numerals, and descriptions that overlap with the above embodiment will be omitted.

[0037] (Variation 1) Fig. 6 is a side view showing a lawnmower system 100 according to Variation 1. As shown in Fig. 6, a recess CP may be formed in the ground F, and a storage unit 72 may be housed in the recess CP. The upper wall 72A of the storage unit 72 is preferably flush with the ground F. In this case, the second side wall 72D of the storage unit 72 may extend in a direction perpendicular to the lower wall 72B. In other words, at least a portion of the storage unit 72 is buried below the surface that contacts the wheels 2 of the lawnmower 1. The ground F includes the floor.

[0038] The recirculation device 70 may include a temporary storage section 80 between the bag 60 and the storage section 72. In this case, the connection section 71C of the duct member 71 is connected to an inlet (not shown) of the temporary storage section 80. The temporary storage section 80 is a container for temporarily storing grass clippings transported via the duct member 71. The temporary storage section 80 has a transport section 81 that transports the grass clippings stored in the temporary storage section 80 to the storage section 72. The transport section 81 may be a pipe member or a belt conveyor.

[0039] (Variation 2) FIG. 7 is a side view showing a lawnmower 1 according to Variation 2. As shown in FIG. 7, in this variation, the lawnmower 1 is provided with a duct member 71x. The duct member 71x is a flow path member through which grass clippings discharged from the outlet 64 of the bag 60 pass. One end 71A of the duct member 71x is connected to the outlet 64. The other end 71B of the duct member 71x is not connected to the storage section 72. The other end 71B of the duct member 71x is open to the outside of the lawnmower 1 and communicates with the atmosphere. In this variation, grass clippings can be scattered onto the ground or the like via the duct member 71x. It is preferable that the duct member 71x be flexible. If the duct member 71x is flexible, it is easier to control the scattering direction of the grass clippings.

[0040] The duct member 71x may branch off from the duct member 71 of the above embodiment. For example, an openable / closable opening is provided between one end 71A and the other end 71B of the duct member 71 of the above embodiment, and one end 71A of the duct member 71x is connected to the opening.

[0041] The duct member 71x may be provided so that the other end 71B faces upward. For example, the duct member 71x is supported by a support member attached to the bag 60 or the like so that the other end 71B faces upward. Having the other end 71B facing upward improves the degree to which the grass clippings discharged from the other end 71B are dispersed before they fall to the ground or the like. This reduces variation in the distribution of the grass clippings scattered on the ground or the like, resulting in a better finished result after scattering.

[0042] The other end 71B of the duct member 71x may be provided with the lid portion (blocking portion) 65 of the above embodiment. Alternatively, if the lid portion 65 has a throttle structure that can change the opening area, the lid portion 65 may be provided inside the duct member 71x.

[0043] 8 is a side view showing a lawnmower system 100 according to Modification 3. The lawnmower system 100 includes a lawnmower 1, a duct member (flow path member) 71, and a storage device 82.

[0044] The storage device 82 stores grass clippings discharged from the duct member 71. The storage device 82 has a storage section 72x and a grass clippings inlet section 73. The storage section 72x differs from the storage section 72 described above in that it does not have a communication port 75. That is, the storage section 72x has an upper wall 72A, a lower wall 72B, a first side wall 72C, a second side wall 72D, a third side wall (not shown), and a fourth side wall (not shown). The storage section 72x allows the lawnmower 1 to be placed on the upper wall 72A. The grass clippings inlet section 73 is provided in the first side wall 72C of the storage section 72x, but is not limited to this.

[0045] The lawn mowing system 100 of this modification allows grass clippings to be stored without being recirculated. The storage device 82 may include the accelerating section 76 of the above embodiment, or the extension section 78 of the above embodiment.
