[Figure 8] Figure 8 is a side view showing a lawn mowing system according to Modification 3. [Modes for carrying out the invention]

[0010] [Embodiment] As shown in Figure 1, the lawn mowing system 100 according to this embodiment comprises a lawn mower 1 and a recirculation device 70. The lawn mower 1 is described as a rotary type lawn mower, but is not limited to this. The lawn mower 1 is a walk-behind self-propelled work machine, but is not limited to this. The lawn mower 1 may also be a robotic work machine.

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

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

[0013] Multiple wheels 2 are rotatably mounted on the body 10. Each set of wheels 2 includes two front wheels 241 positioned on the left and right sides, and two rear wheels 242 positioned on the left and right sides. The lawnmower 1 can move by the rotation of these wheels 2. The number of wheels 2 on the lawnmower 1 is not limited to four.

[0014] The power source 4 is mounted, for example, on the upper part of the body section 10. The power source 4 may include a drive motor and a work motor. The drive motor is a drive unit that rotates multiple wheels 2. The work motor is a drive unit that rotates the blade 50. 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 section 110. The center of the swivel section 110 coincides with the axis SC of the output shaft 40. The swivel section 110 is a space enclosed by a top plate 11a (Figure 5), an outer cylinder section 111, and an inner cylinder section 112 (Figure 4). The outer cylinder section 111 is formed in a cylindrical shape. The upper end of the outer cylinder section 111 is connected to the top plate 11a. The center of the outer cylinder section 111 coincides with the axis SC of the output shaft 40. The inner cylinder section 112 is formed in a cylindrical shape. The outer diameter of the inner cylinder section 112 is smaller than the outer diameter of the outer cylinder section 111. The upper end of the inner cylinder section 112 is connected to the top plate 11a. The center of the inner cylinder section 112 coincides with the axis SC of the output shaft 40.

[0016] A passage opening 113 is located at the right rear of the swivel section 110, opening upward and rearward. The transport passage 12 is connected to the passage opening 113. The transport passage 12 is a passage for transporting the cut grass. The transport passage 12 is provided in the body section 10. The cut grass is fragments of turf grass cut by the blade 50. As shown in Figure 5, the transport 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 transport passage 12.

[0017] As shown in Figure 4, the loading passage 12 extends rearward along approximately tangential directions to the outer cylindrical portion 111 of the rotating section 110 when viewed from above. As shown in Figure 5, the loading passage 12 extends rearward and upward when viewed from left to right. The downstream opening 122 of the loading passage 12 opens to the rear.

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

[0019] The grass cut by the blade 50 is carried away by the airflow. The grass flows into the discharge passage 12 through the passage opening 113 of the swivel section 110. The grass that flows into the discharge passage 12 flows 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 equipped with an opening adjustment mechanism to adjust the degree of opening of the downstream opening 122.

[0020] As shown in Figures 1 and 2, the bag 60 is a container for holding the mowed grass. The bag 60 is made of a soft material, but is not limited to that. The bag 60 may be made of a strong material, such as a plastic case. The bag 60 is positioned to cover the downstream opening 122 of the discharge passage 12. The bag 60 is attached to the bag attachment part 13. The bag attachment part 13 is provided at the downstream opening 122 of the discharge passage 12. When the bag 60 is attached to the bag attachment part 13, the inside of the bag 60 and the discharge passage 12 are in communication. The bag 60 holds the mowed grass that is discharged from the body part 10 through 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, about the upper end thereof as the rotation axis. When the bag 60 is removed from the bag attachment portion 13, the downstream opening 122 of the carry-out passage 12 is blocked 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 be formed on the lower end face 63B. The inlet 61 is connected to the downstream opening 122 of the carry-out 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 the rear in the front-rear direction of the bag 60. When the inlet 61 is formed on the front end face 63D, the rear end face 62 is located on the side opposite to the inlet 61. The upper end face 63A faces upward in the up-down direction of the bag 60. The lower end face 63B faces downward in the up-down direction of the bag 60. The left end face 63C faces left in the left-right direction of the bag 60. The right side face not shown faces right in the left-right direction of the bag 60. The front end face 63D faces forward in the front-rear direction of the bag 60. The upper end face 63A, the lower end face 63B, the left end face 63C, and the right side face not shown extend from the inlet 61 (front end face 63D) to the rear end face 62. The rear end face 62 may be substantially rectangular.

[0023] On the rear end face 62, an outlet 64 for discharging the mowed grass is formed. Instead of the rear end face 62, the outlet 64 may be formed on the upper end face 63A, the lower end face 63B, the left end face 63C or a right end face not shown. A plurality of outlets 64 may be formed. In this case, the outlets 64 may be formed one by one on at least two of the rear end face 62, the upper end face 63A, the lower end face 63B, the left end face 63C and the right end face not shown. Alternatively, a plurality of outlets 64 may be formed on the rear end face 62, the upper end face 63A, the lower end face 63B, the left end face 63C or the right end face not shown. Or, these may be combined. Note that the inlet 61 and the outlet 64 are separated. A lid portion (closing portion) 65 (Fig. 3) is attached to the outlet 64. The lid portion 65 closes the entire outlet 64, but may also close a part thereof. Since the lid portion 65 is attached to the outlet 64, the mowed grass conveyed from the downstream opening 122 of the carrying passage 12 is housed inside the bag 60 without being discharged from the outlet 64. The lid portion 65 is removable from the outlet 64.

[0024] When the lid portion 65 is removed from the outlet 64, at least a part of the mowed grass located inside the bag 60 flows out from the outlet 64 due to the airflow generated by the rotation of the blade 50. Therefore, the mowed grass can be discharged outside the bag 60 without removing the bag 60. As described above, the outlet 64 is formed on the rear end face 62 on the opposite side of the inlet 61 connected to the downstream opening 122. For this reason, the mowed grass flowing into the bag 60 through the downstream opening 122 can be efficiently discharged outside the bag 60. The lid portion 65 may have a throttle structure with a variable opening area. In this case, the amount of the mowed grass flowing out from the outlet 64 can be adjusted without removing the lid portion 65 from the outlet 64. Therefore, when the lid portion 65 has a structure capable of changing the opening area of the outlet 64, the lid portion 65 may be arranged inside the bag 60.

[0025] As shown in Figure 1, the recirculation device 70 includes a duct member (flow channel member) 71 and a storage section (storage device) 72. The duct member 71 is a member that allows the grass clippings discharged from the outlet 64 of the bag 60 to pass through. 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 on the opposite side of the one end 71A. A connecting portion 71C is provided at the other end 71B of the duct member 71. The connecting portion 71C is formed to be connectable to the storage section 72.

[0026] The storage section 72 is a container capable of storing the grass clippings discharged from the duct member 71. The storage section 72 is located 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 lawnmower 1 can be placed on the upper wall 72A of the storage section 72. In other words, the storage section 72 is formed so that the lawnmower 1 can be supported by the upper wall 72A.

[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 along a direction perpendicular to the lower wall 72B. A grass clipping inlet 73 is formed in the first side wall 72C. A connection portion 71C of the duct member 71 can be connected to the grass clipping 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 is sloped so that it becomes higher from the lower wall 72B towards the upper wall 72A. The second side wall 72D can function as a ramp section 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 inside of the storage section 72 to the outside of the storage section 72.

[0029] As described above, the lawnmower 1 is mounted on the upper wall 72A. The lawnmower 1 is mounted on the upper wall 72A such that the blade 50 is positioned above the communication opening 75. When the blade 50 rotates, the cut grass located in the storage section 72 rises due to the airflow generated by the rotation. In this case, the cut grass that has risen due to the airflow flows into the housing 11 through the communication opening 75 formed at the location reached by the airflow and is shredded by the blade 50.

[0030] The shredded grass passes through the swivel section 110 and the discharge passage 12 of the housing 11 in that order and flows into the bag 60. The grass located in the bag 60 can be transported (recirculated) from the outlet 64 to the storage section 72 via the duct member 71. The grass in the storage section 72 can pass through the communication opening 75 and reach the blade 50. With the grass recirculated to the blade 50, the lawnmower 1 rotates the blade 50 to re-shred the recirculated grass.

[0031] In this way, a circulation path is established through which the cut grass is circulated via the blade 50. This allows the cut grass collected in the bag 60 to be made finer, and as a result, the amount of cut grass that can be collected in the bag 60 can be increased. The circulation path includes the discharge passage 12, the bag 60, the duct member 71, and the storage section 72.

[0032] The recirculation device 70 of the lawn mowing system 100 is equipped with a suction fan motor (facilitator) 76 that promotes the flow of mowed grass flowing out from the outlet 64. In Figure 1, the suction fan motor 76 is located near the mowed grass inlet 73 inside the storage section 72. The suction fan motor 76 promotes the flow of mowed grass flowing out from the outlet 64 by sucking mowed grass from the duct member 71. As a result, the mowed grass is easily transported (recirculated). The suction fan motor 76 may be replaced with a blower fan motor. In this case, the blower fan motor is located near the communication port 75 inside the storage section 72. The blower fan motor blows air onto the mowed grass rising towards the communication port 75, promoting the flow of mowed grass flowing out from the outlet 64 and stored in the storage section 72. As a result, the mowed grass is easily transported (recirculated).

[0033] The recirculation device 70 of the lawn mowing system 100 includes an extension portion 78 that extends upward from the outer surface (upper wall surface) of the upper wall 72A. The extension portion 78 restricts the outflow of at least some of the debris from the opening 11o of the lawn mower 1 to the outside of the body portion 10. The debris includes sand, dust, and cut grass. The extension portion 78 is formed of an elastic material such as rubber. The extension portion 78 is in contact with the body portion 10, but there may be a small gap between it and the body portion 10. The extension portion 78 is located behind the blade 50, but it may be located on the outer periphery of the opening 11o. The extension portion 78 may be detachable from the storage portion 72.

[0034] The recirculation device 70 of the lawn mowing system 100 is equipped with a mesh member (intervening member) 79 at the communication port 75. The mesh member 79 is interposed in the communication port 75 and has a mesh structure. The mesh member 79 suppresses the flow of cut grass through the communication port 75, while allowing the flow of air through the communication port 75. The communication port 75 is formed in the upper wall 72A, but is not limited to this. The communication port 75 may be formed in a location other than the upper wall 72A of the storage section 72, as long as it is a location to which the airflow accompanying the rotation of the blade 50 reaches.

[0035] As described above, this embodiment provides a better lawnmower 1 and lawnmower system 100.

[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 are omitted.

[0037] (Variation 1) Figure 6 is a side view showing a lawn mowing system 100 according to Modification 1. As shown in Figure 6, a recess CP may be formed in the ground F, and the storage section 72 may be housed in the recess CP. Preferably, the upper wall 72A of the storage section 72 is flush with the ground F. In this case, the second side wall 72D of the storage section 72 may extend in a direction perpendicular to the lower wall 72B. In other words, at least a portion of the storage section 72 is embedded below the surface to which the wheels 2 of the lawn mower 1 make contact. The ground F includes the floor surface.

[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 the inlet (not shown) of the temporary storage section 80. The temporary storage section 80 is a container for temporarily storing the grass clippings transported via the duct member 71. The temporary storage section 80 has a transport section 81 that transports the grass clippings contained 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] (Modification 2) Figure 7 is a side view showing a lawnmower 1 according to Modification 2. As shown in Figure 7, in this modification, a duct member 71x is provided on the lawnmower 1. The duct member 71x is a flow channel member through which the 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 modification, the grass clippings can be scattered on the ground, etc., via the duct member 71x. It is preferable that the duct member 71x is bendable. If the duct member 71x is bendable, it is easier to control the direction of grass clipping scattering.

[0040] The duct member 71x may be branched from the duct member 71 of the above embodiment. For example, an openable and closable opening may be 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 may be connected to this opening.

[0041] The duct member 71x may be provided such that its other end 71B points upward. For example, the duct member 71x is supported by a support member attached to a bag 60 or the like so that its other end 71B points upward. By having the other end 71B pointing upward, the degree of dispersion of the grass clippings discharged from the other end 71B before they fall to the ground is improved. Therefore, variations in the distribution of grass clippings scattered on the ground can be reduced, resulting in a better finish after scattering.

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

[0043] (Variation 3) Figure 8 is a side view showing a lawn mowing system 100 according to modified example 3. The lawn mowing system 100 comprises a lawn mower 1, a duct member (flow channel member) 71, and a storage device 82.

[0044] The storage device 82 stores the grass clippings discharged from the duct member 71. The storage device 82 has a storage section 72x and a grass clipping inlet 73. The storage section 72x differs from the storage section 72 in that it does not have a communication opening 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 lawnmower 1 can be placed on the upper wall 72A of the storage section 72x. The grass clipping inlet 73 is provided on the first side wall 72C of the storage section 72x, but is not limited to this.

[0045] According to this modified lawn mowing system 100, the mowed grass can be stored without being recirculated. The storage device 82 may be equipped with the acceleration section 76 of the above embodiment, or it may be equipped with the extension section 78 of the above embodiment.
