The tail part refers to the rear end part of the mowing device 1000 along the length direction X.

[0045] The swing lever 50 is fixedly connected with the grass collecting box 200 through the rotating shaft 220. Specifically, the end of the rotating shaft 220 along the rotating axis 221 is provided with an anti-rotation head 222, and the swing lever 50 is provided with an anti-rotation groove 503 matched with the anti-rotation head 222, so as to realize the fixed connection of the swing lever 50 and the rotating shaft 220, and then when the swing lever 50 rotates, the swing lever 50 can drive the grass collecting box 200 to perform a turnover motion, thereby realizing the grass unloading function of the grass collecting box 200. The anti-rotation groove 503 can be configured as a through groove, i.e., the anti-rotation groove 503 penetrates through the two side walls of the swing lever 50 in the width direction Z of the turnover assembly 300, thereby facilitating the machining and manufacturing of the anti-rotation groove 503. Of course, in some embodiments, the anti-rotation groove 503 can also be configured as a blind groove, thereby improving the overall structural strength of the swing lever 50 and prolonging the service life of the swing lever 50.

[0046] Of course, in some embodiments, the swing lever 50 and the rotating shaft 220 can be fixedly connected together through a locking structure such as a buckle or a bolt, and the utility model does not make a specific limitation. The swing lever 50 and the grass collecting box 200 can be detachably connected, thereby facilitating the maintenance, replacement, cleaning and other operations of the grass collecting box 200 and the turnover assembly 300. The swing lever 50 and the grass collecting box 200 can also be connected in a non-detachable manner through welding, bonding or other means. In other embodiments, the rotating shaft 220 can be omitted, i.e., the swing lever 50 is directly fixedly connected with the grass collecting box 200.

[0047] The swing lever 50 has a swing trajectory 505. The swing trajectory 505 is a trajectory of the swing of the swing lever 50 around the axis of the rotating shaft 220. The axis of the rotating shaft 220 refers to a position passing through the rotating axis 221 of the rotating shaft 220 and passing through the connection center of the rotating shaft 220 and the swing lever 50. The swing trajectory 505 is circular. The swing radius is the distance between the hinged point of the swing lever 50 and the sliding member 40 and the connection center point of the swing lever 50 and the rotating shaft 220.

[0048] In some embodiments, the support framework 240 is further arranged on the grass collecting box 200, thereby improving the overall structural strength of the grass collecting box 200 and enhancing the load-bearing capacity of the grass collecting box 200, and prolonging the service life of the grass collecting box 200. For example, the grass collecting box 200 can be configured as a flexible grass collecting bag, and the support framework 240 is used to open the flexible grass collecting bag, so that the grass collecting box 200 maintains an inherent shape, improves the grass collecting effect of the grass collecting box 200, and realizes detachable connection of the grass collecting box 200 and the support framework 240, thereby improving the assembly efficiency. The grass collecting box 200 can also be configured as a rigid box structure. Specifically, the support framework 240 is arranged at the intersection of different side walls of the grass collecting box 200.

[0049] The support framework 240 includes a first framework 241 and a second framework 242. The first framework 241 is arranged on the grass collecting box 200, one end of the second framework 242 is connected with the first framework 241, and the other end of the second framework 242 is connected with the rotating shaft 220. In this way, the assembly efficiency between the grass collecting box 200 and the rotating shaft 220 can be improved while improving the structural strength of the grass collecting box 200. Specifically, the rotating shaft 220 is provided with a mounting hole 223 for mounting the second framework 242.

[0050] In some embodiments, the support framework 240 further includes a handle 243. The handle 243 is used to drive the grass collecting box 200 to overturn relative to the rotating shaft 220, thereby realizing the manual and automatic grass discharging functions of the grass collecting box 200, enriching the use scenarios of the grass collecting box 200, and improving the user experience. The handle 243 can be arranged at the middle part of the top of the grass collecting box 200. In this way, on the one hand, when the user applies a force to the handle 243, the grass collecting box 200 is uniformly stressed, stress concentration is avoided, the service life of the grass collecting box 200 is prolonged, use is convenient, and operation is simple; on the other hand, the top space of the grass collecting box 200 is reasonably utilized, and the space utilization rate is improved. Of course, in other embodiments, the handle 243 can also be arranged at other positions of the grass collecting box 200. Specifically, the handle 243 can be indirectly connected with the grass collecting box 200 through the support framework 240; or the handle 243 can be directly connected with the grass collecting box 200.

[0051] Please refer to Figure 3 and Figure 4 , Figure 4 areFigure 3 It is to be noted that the hinging described in the embodiments of the present application includes the pivotal connection of two elements or the spherical hinging of two elements. For example, in the present embodiment, the sliding member 40 and the swing lever 50 can be pivotally connected through the pivot shaft 62. Specifically, the sliding member 40 and the swing lever 50 are respectively provided with pivot holes 501 through which the pivot shaft 62 passes, so that the swing lever 50 can rotate about the central axis of the pivot shaft 62. The central axis of the pivot shaft 62 is perpendicular to the sliding direction of the sliding member 40. Of course, in some embodiments, the pivot shaft 62 can be fixed on the swing lever 50 and slidably or rotatably arranged on the sliding member 40, thereby simplifying the assembly operation of the pivot shaft 62. Of course, in some embodiments, the sliding member 40 and the swing lever 50 can also be spherical hinged. The sliding member 40 is provided with a spherical protrusion, and the swing lever 50 is provided with a spherical groove in sliding cooperation or rotational cooperation with the spherical protrusion; or the swing lever 50 is provided with a spherical groove, and the sliding member 40 is provided with a spherical protrusion in cooperation with the spherical groove. The spherical protrusion is rotatably or slidably accommodated in the spherical groove. The swing lever 50 can rotate in any direction about the spherical center of the spherical protrusion.

[0052] In the present embodiment, the sliding member 40 includes a first sliding part 41 and a second sliding part 42. The first sliding part 41 is in transmission connection with the driving member 20, and the second sliding part 42 is fixedly connected with the first sliding part 41 and is in sliding hinging with the swing lever 50. In this way, on the one hand, the swing lever 50 and the sliding member 40 are directly sliding hinged, thereby improving the utilization rate of the torque generated by the sliding member 40 on the swing lever 50, so that the hay collecting box 200 can save time and labor when unloading the hay; on the other hand, the hinging end of the swing lever 50 and the second sliding part 42 moves along the tangent direction of the arc trajectory of the swing lever 50, so that the swing trajectory 505 of the swing lever 50 is strictly limited in the tangent direction of the arc, thereby enabling the hay collecting box 200 to move along a smooth and accurate movement trajectory; on the other hand, the turnover assembly 300 omits the connecting rod connecting the swing lever 50 and the sliding member 40, thereby simplifying the structure of the turnover assembly 300 and making the structure compact.

[0053] The second sliding part 42 is arranged on the side of the first sliding part 41 towards the side of the swing lever 50. Specifically, the second sliding part 42 is arranged on the side wall of the first sliding part 41 in the width direction Z of the turnover assembly 300. In this way, on the one hand, the swing lever 50 is prevented from interfering with the movement of the driving member 20, improving the smoothness and safety of the swing movement of the swing lever 50 and the sliding movement of the sliding member 40; on the other hand, the space occupied by the second sliding part 42 in the height direction Y of the turnover assembly 300 is reduced, improving the compactness of the overall structure of the turnover assembly 300. The second sliding part 42 and the first sliding part 41 can be integrally formed, thereby improving the overall structural strength of the sliding member 40 and the connection reliability and stability between the second sliding part 42 and the first sliding part 41. Of course, the second sliding part 42 and the first sliding part 41 can also be detachably connected together, thereby facilitating the processing and manufacturing of the sliding member 40 and the maintenance of the sliding member 40 and various parts connected thereto.

[0054] Of course, in some embodiments, the turnover assembly 300 further comprises a connecting rod. One end of the connecting rod is hingedly connected to the sliding member 40, and the other end of the connecting rod is hingedly connected to the swing lever 50. In this way, the sliding block, the connecting rod, and the swing lever 50 form a crank slider structure, which on the one hand makes the overall structure of the turnover assembly 300 simple, easy to design and manufacture, and reduces maintenance costs; on the other hand, the design of the crank slider mechanism makes the power transmission path shorter and the power loss smaller, thereby improving the power transmission efficiency of the driving mechanism.

[0055] In some embodiments, the turnover assembly 300 further comprises a rolling bearing member 60, and the swing lever 50 is slidingly hingedly connected to the second sliding part 42 through the rolling bearing member 60. In this way, the rolling bearing 61 can reduce the friction between the swing lever 50 and the sliding member 40, so that the hay collector 200 can save time and effort when unloading.

[0056] Specifically, in the present embodiment, the rolling bearing member 60 comprises a rolling bearing 61, a pivot shaft 62, and a snap spring 63. One end of the pivot shaft 62 is provided with a clamping groove 621, and the snap spring 63 is installed in the clamping groove 621. The snap spring 63 is used to press and install the rolling bearing 61 and the swing lever 50 on the sliding member 40. In this way, the snap spring 63 can tightly fit on a specific position of the pivot shaft 62, preventing the rolling bearing 61 and the swing lever 50 from loosening or falling off from the sliding member 40, thereby improving the reliability and stability of the connection between the swing lever 50 and the sliding member 40; on the other hand, the installation and removal of the snap spring 63 are relatively convenient, thereby improving the assembly and disassembly efficiency of the swing lever 50 and the sliding member 40. Of course, in other embodiments, the rolling bearing 61 can also be connected to the sliding member 40 and the swing lever 50 through a rivet; or the turnover assembly 300 can omit the rolling bearing 61, i.e., the sliding member 40 and the swing lever 50 are hingedly connected through the pivot shaft 62.

[0057] The pivot shaft 62 is configured as a rigid shaft, thereby avoiding lateral movement of the rolling bearing 61, so that the rolling bearing 61 slides along the extension direction of the sliding groove 402, and the smoothness and reliability of the swinging movement of the swing lever 50 are improved. The other end of the pivot shaft 62 is provided with a stop portion 622 for stopping the swing lever 50. The swing lever 50, the rolling bearing 61 and the second sliding portion 42 are clamped between the stop portion 622 and the snap spring 63, thereby realizing the hinging of the sliding piece 40 and the swing lever 50. Specifically, the swing lever 50 includes a first connecting portion 51, a second connecting portion 52 and a lever body portion 53. The lever body portion 53 is connected between the first connecting portion 51 and the second connecting portion 52. The first connecting portion 51 is provided with a pivot hole 501 through which the pivot shaft 62 passes. The first connecting portion 51 is provided with a positioning groove 502 at the edge of the pivot hole 501, and the stop portion 622 is accommodated in the positioning groove 502, thereby facilitating the alignment assembly of the pivot shaft 62 and the swing lever 50, avoiding the stop portion 622 of the pivot shaft protruding outward relative to the swing lever 50, affecting the appearance, and reducing the occupied space of the stop portion 622, so that the overall structure of the turnover assembly 300 is more compact. Of course, in some embodiments, the stop portion 622 can not be provided with the positioning groove 502, that is, the stop portion 622 abuts against the side wall of the first connecting portion 51 away from the sliding piece 40. The second connecting portion 52 is provided with an anti-rotation groove 503 matched with the anti-rotation head 222 of the rotating shaft 220. The anti-rotation groove 503 is configured as a waist-shaped groove.

[0058] The second sliding portion 42 is provided with a movable hole 401. The pivot shaft 62 is slidably arranged in the movable hole 401, thereby realizing the sliding hinging of the swing lever 50 and the sliding piece 40. Since the sliding hinging has the characteristics of reliable force transmission, flexible rotation, and the ability to withstand large load and rotation torque, the sliding hinging of the swing lever 50 and the sliding piece 40 can prolong the service life of the turnover assembly 300.

[0059] In some embodiments, the movable hole 401 is upwardly inclined relative to the horizontal plane towards the side of the hay tank 200, and the horizontal plane is perpendicular to the height direction Y of the turnover assembly 300. Thus, based on the extension direction of the movable hole 401 being upwardly inclined relative to the horizontal plane, the position of the swing lever 50 is always moved in one direction when the swing lever 50 is pushed to swing, without running to the other side to form resistance or being unable to reset, thereby making the swing lever 50 in a labor-saving state when resetting. On the other hand, the movable hole 401 can also provide a guiding effect for the sliding movement of the swing lever 50 relative to the sliding piece 40, thereby improving the smoothness and reliability of the turnover movement of the swing lever 50 driving the hay tank 200.

[0060] In some embodiments, the second sliding part 42 is provided with a sliding groove 402 on the side facing away from the first sliding part 41. The rolling bearing piece 60 is in sliding fit with the sliding groove 402. In this way, on the one hand, the sliding groove 402 can provide guidance for the rolling of the rolling bearing 61, improving the smoothness and reliability of the overturning movement of the hay collecting box 200 driven by the swing lever 50; on the other hand, the rolling bearing piece 60 is accommodated in the sliding groove 402, thereby reducing the occupied volume of the rolling bearing 61, so that the overall structure of the overturning assembly 300 is simple and compact.

[0061] In some embodiments, the sliding groove 402 is upwardly inclined relative to the horizontal plane towards the side of the hay collecting box 200, and the horizontal plane is perpendicular to the height direction Y of the overturning assembly 300. In this way, based on the upward inclination of the sliding groove 402 relative to the horizontal plane towards the side of the hay collecting box 200, the position of the swing lever 50 can always move in one direction when the swing lever 50 is pushed to swing, without running to the other side to form resistance or failing to reset, thereby making the swing lever 50 in a labor-saving state when resetting.

[0062] Specifically, in the extension direction of the sliding groove 402, the sliding groove 402 includes opposite first and second ends 4021 and 4022. The first end 4021 is located on the side of the second end 4022 facing away from the hay collecting box 200, and the distance between the first end 4021 and the mounting seat 10 is less than the distance between the second end 4022 and the mounting seat 10.

[0063] In some embodiments, the groove bottom of the sliding groove 402 is provided with a convex rib 403 abutting against the rolling bearing piece 60. In this way, the friction between the rolling bearing 61 and the second sliding part 42 is reduced, so that the hay collecting box 200 can save time and labor when unloading. In the present embodiment, the convex rib 403 is provided in two, and the two convex ribs 403 are arranged at the edges of the movable hole 401, and the extension direction of the convex rib 403 is parallel to the extension direction of the movable hole 401, thereby improving the smoothness and reliability of the rolling of the rolling bearing 61 relative to the convex rib 403, and reducing the friction between the rolling bearing 61 and the second sliding part 42. In some embodiments, the distance between the two convex ribs 403 is substantially equal to the outer diameter of the pivot shaft 62, so that the convex rib 403 can also provide guidance for the sliding movement of the swing lever 50 relative to the sliding part 40, improving the smoothness and reliability of the overturning movement of the hay collecting box 200 driven by the swing lever 50.

[0064] The included angle between the extension direction of the sliding groove 402 and the horizontal plane is a first included angle a, and the first included angle a is 10°. It can be understood that when the swing rod 50 swings to the same swing angle, the greater the angle value of the first included angle a, the greater the sliding distance of the sliding piece 40, and the greater the driving force output by the driving piece 20. The utility model is based on setting the first included angle a in a proper range, so that the swing rod 50 can be in a labor-saving state during the resetting process after discharging grass, and the utilization rate of the output power of the driving piece 20 is improved, energy consumption is saved, and the overall structure of the turnover assembly 300 is more compact.

[0065] Please refer to Figure 4 、 Figure 7 and Figure 8 , Figure 7 is Figure 1 the structure schematic view of the turnover assembly 300 of the grass cutting equipment 1000 in the collecting state in FIG. Figure 8 is Figure 1 the structure schematic view of the turnover assembly 300 of the grass cutting equipment 1000 in the discharging state in FIG. In the embodiment, the maximum swing angle of the swing rod 50 is a second included angle β. The second included angle β is 50°-80°. Therefore, on the one hand, the grass collecting box 200 can realize a larger turnover angle, and the discharging efficiency is improved; on the other hand, the turnover angle of the grass collecting box 200 is avoided to be too large. For example, the second included angle β can be but is not limited to 50°, 60°, 70° or 80°. The first included angle a is the complementary angle of the second included angle β. Exemplarily, in the embodiment, the maximum swing angle of the swing rod 50 is 80°, that is, the second included angle β is 80°, and the first included angle a is 10°. Of course, in some embodiments, the maximum swing angle of the swing rod 50 can also be greater than 80° and less than or equal to 90°. The second included angle β is only used for illustration, and the maximum swing angle of the swing rod 50 can be set according to the connection mode of the swing rod 50 and the sliding piece 40, the specification of the grass collecting box 200 and other factors, and the embodiment of the utility model is not limited specifically.

[0066] In the embodiment, the swing angle of the swing rod 50 is equal to the overturning angle of the hay collecting box 200, so as to facilitate accurate control of the overturning angle of the hay collecting box 200. The hay collecting box 200 is arranged to be inclined upward relative to the horizontal plane. Specifically, in the height direction Y of the overturning assembly 300, the top wall or the bottom wall of the hay collecting box 200 is arranged to be inclined upward relative to the horizontal plane from the first end 4021 to the second end 4022. Thus, the inclined arrangement of the hay collecting box 200 can enhance the bearing capacity and stability of the entire hay collecting box 200. Specifically, the top wall or the bottom wall of the hay collecting box 200 is inclined relative to the horizontal plane at a third included angle γ. The third included angle γ is complementary to the second included angle β. For example, in the embodiment, the third included angle γ is 10°. The third included angle γ is only used for illustration, and the third included angle γ can be designed according to the specifications of the hay collecting box 200, the configuration of the overturning assembly 300 and other factors, and the embodiment of the utility model is not limited specifically.

[0067] Specifically, the swing trajectory 505 of the swing rod 50 has a first limit position P1 and a second limit position P2. The first limit position P1 is the position of the swing rod 50 when the hay collecting box 200 is in the hay collecting state, that is, the end of the swing rod 50 hinged to the sliding member 40 is located at the first end 4021 of the sliding groove 402. The second limit position P2 is the position of the swing rod 50 when the hay collecting box 200 is in the hay unloading state and the overturning angle of the hay collecting box 200 reaches the maximum, that is, the end of the swing rod 50 hinged to the sliding member 40 is located at the second end 4022 of the sliding groove 402. The swing angle of the swing rod 50 refers to the angle corresponding to the swing of the swing rod 50 from the first limit position P1 to the second limit position P2, that is, the maximum swing angle of the swing rod 50. During the hay unloading process, the swing rod 50 can swing to any angle below the maximum swing angle, so that the hay collecting box 200 can be overturned to a suitable angle according to the hay collecting amount.

[0068] When the swing rod 50 swings to the first limit position P1, the extension direction of the swing rod 50 is substantially perpendicular to the sliding direction of the sliding member 40. In other words, when the swing rod 50 swings to the first limit position P1, the extension direction of the swing rod 50 is substantially parallel to the length direction X of the overturning assembly 300. Thus, when the hay collecting box 200 is in the hay collecting state, the swing rod 50 can provide stable support force, avoiding the need for the swing rod 50 to bear additional force and torque due to the inclination of the swing rod 50, so that the support rod cannot provide stable support force for the hay collecting box 200.

[0069] It should be noted that the term "parallel" refers to two straight lines in a plane, two planes in space, and a line and a plane in space without any common points. The term "perpendicular" refers to a line intersecting another line at a right angle, and the two lines are perpendicular to each other. In the embodiments of the present application, the descriptions such as parallel and perpendicular can include the cases of approximate parallel and approximate perpendicular due to processing errors, measurement errors, etc. For example, the two lines in this paper can include the case of two lines being completely parallel, and can also include the case of two lines being approximately parallel. The two lines in this paper can include the case of two lines being completely perpendicular, and can also include the case of two lines being approximately perpendicular.

[0070] Please refer to Figures 4 to 6 , Figure 5 is Figure 3 is a top view of the turnover assembly 300 in the Figure 6 is Figure 5 is a sectional view of the turnover assembly 300 along B-B in the turnover assembly 300. The driving member 20 includes a driving part 21 and a transmission part 22, the driving part 21 is in transmission connection with the transmission part 22, the transmission part 22 is in transmission connection with the sliding member 40, and the transmission part 22 is configured as a lead screw, a telescopic rod or a movable pulley traction structure. Exemplarily, in the present embodiment, the driving part 21 is configured as a driving motor, the transmission part 22 is configured as a lead screw, and the sliding member 40 is provided with a threaded hole 404 in screw connection with the transmission part 22. Thus, based on the setting that the sliding member 40 is rotatably slidable relative to the lead screw, the stability of the sliding movement of the sliding member 40 is improved, and the lead screw itself has a certain self-locking ability, so that the transmission between the lead screw and the sliding member 40 will not have too much gap or error, and the use safety of the turnover assembly 300 is improved, and the cost of the turnover assembly 300 is reduced.

[0071] In some embodiments, the driving member 20 can be configured as a pneumatic cylinder or an oil cylinder, and the transmission part 22 is configured as a telescopic rod, so that the driving member 20 can output larger driving force and drive the larger size grass collecting box 200 to unload the grass. Understandably, the larger the size of the grass collecting box 200, the greater the weight of the grass in the grass collecting box 200 when the grass collecting box 200 is full of grass. Although the pneumatic cylinder or the oil cylinder can output larger driving force, the cost of the driving member 20 is relatively high. The present application adopts the cooperation of the driving motor and the lead screw transmission, thereby reducing the cost of the driving member 20, and through the sliding hinge of the swing lever 50 and the sliding member 40, thereby improving the utilization rate of the driving force output by the driving member 20, so that the grass collecting box 200 saves time and labor in the process of unloading the grass.

[0072] Exemplarily, in the embodiment, when the transmission part 22 is configured as a lead screw, the driving member 20 further comprises a driving gear 23 and a driven gear 24, the driven gear 24 is fixedly connected with the lead screw, the driving part 21 is in transmission connection with the driving gear 23 and the driven gear 24, and is used for driving the driving gear 23 to rotate, so as to drive the driven gear 24 and the sliding member 40 to rotatably slide relative to the transmission part 22, the driving part 21 and the transmission part 22 are arranged on the same side of the mounting seat 10, and the diameter of the driving gear 23 is smaller than the diameter of the driven gear 24. Thus, on the one hand, based on the arrangement that the sliding member 40 rotatably slides relative to the lead screw, the stability of the sliding motion of the sliding member 40 is improved, and the lead screw itself has a certain self-locking ability, so that the transmission between the lead screw and the sliding member 40 will not have too much gap or error, and the use safety of the turnover assembly 300 is improved; on the other hand, the driving part 21 and the transmission part 22 are arranged on the same side of the mounting seat 10, which reduces the occupied space of the driving member 20 in the height direction Y of the turnover assembly 300, improves the space utilization, and has a compact structure; on the other hand, based on the arrangement that the diameter of the driving gear 23 is smaller than the diameter of the driven gear 24, the driven gear 24 with a large diameter can act as a force amplifier, so that the driving member 20 can output a smaller driving force to drive the sliding member 40 to move up and down and drive the swing rod 50 to rotate, and then the turnover assembly 300 drives the grass collecting box 200 to unload grass, which can save time and effort and improve work efficiency. The output shaft of the driving part 21 and the rotation axis 221 of the transmission part 22 are arranged in parallel and spaced apart. Of course, in some embodiments, the driving member 20 can not include the driving gear 23 and the driven gear 24, that is, the output shaft of the driving part 21 and the rotation axis 221 of the transmission part 22 are coaxially arranged.

[0073] Please refer to Figure 1 and Figure 9 , Figure 9 is a structural schematic view of a turnover assembly 300 of a mowing equipment 1000 in a grass unloading state according to the second embodiment of the utility model. In the second embodiment, the structure of the turnover assembly 300 is similar to that of the turnover assembly in the first embodiment. The difference is that the transmission part 22 is configured as a dynamic pulley traction structure.

[0074] Specifically, the transmission part 22 comprises a movable pulley 225 and a traction rope 226. The sliding member 40 is fixedly connected with the movable pulley 225, and one end of the traction rope 226 is fixed on the limiting seat 30. The traction rope 226 is wound around the movable pulley 225. In this way, on the one hand, the movable pulley 225 is essentially a lever with a power arm equal to twice a resistance arm, so that the transmission part 22 configured as a movable pulley traction structure can save half of the force. Of course, in some embodiments, the transmission part 22 further comprises a fixed pulley 227. The fixed pulley 227 is fixed on the limiting seat 30, and the traction rope 226 is wound around the fixed pulley 227 to realize that one end of the traction rope 221 is fixed on the limiting seat 30 through the fixed pulley 227.

[0075] It can be understood that when the driving part 21 tightens the traction rope 226, the movable pulley 225 drives the sliding member 40 to move upward toward the side away from the mounting seat 10, and the swing rod 50 connected with the rolling bearing 61 slides from the second end 4022 to the first end 4021 of the sliding groove 402, so as to realize that the grass collecting box 200 is turned over toward the side close to the machine body 100, so as to reset the grass collecting box 200 to the grass collecting state. When the driving part 21 releases the traction rope 226, the movable pulley 225 drives the sliding member 40 to move downward toward the side close to the mounting seat 10, and the swing rod 50 connected with the rolling bearing 61 slides from the first end 4021 to the second end 4022, so as to realize that the grass collecting box 200 is turned over toward the side away from the machine body 100, so as to reset the grass collecting box 200 to the grass discharging state. The driving part 21 realizes that the swing rod 50 swings around the axis of the rotating shaft 220 from the first limit position P1 to the second limit position P2 by controlling the tension state of the traction rope 226.

[0076] In some embodiments, the turnover assembly 300 further comprises a first bearing 26. The two ends of the transmission part 22 are respectively installed on the mounting seat 10 and the limiting seat 30 through the first bearing 26. In this way, on the one hand, the setting of the first bearing 26 can reduce the friction between the transmission part 22 and the mounting seat 10 and the limiting seat 30, improve the smoothness of the rotation of the transmission part 22, reduce the energy consumption, and improve the utilization rate of the driving force output by the driving part 20; on the other hand, the setting of the first bearing 26 can also effectively protect the transmission part 22, prevent the transmission part 22 from being damaged due to external force, and prolong the service life of the turnover assembly 300; on the other hand, the first bearing 26 can also bear the axial load and improve the guiding effect for the rotation of the transmission part 22, thereby improving the rotation accuracy of the transmission part 22.

[0077] In some embodiments, the overturning assembly 300 can further comprise a second bearing 27. At least one end of the guide rod 70 is mounted on the mounting base 10 and the limiting seat 30 through the first bearing 26. In this way, on the one hand, the provision of the second bearing 27 can reduce the friction between the guide rod 70 and the mounting base 10 or the limiting seat 30, improve the smoothness of the rotation of the transmission gear 25, reduce the energy consumption, and improve the utilization rate of the driving force output by the driving member 20; on the other hand, the provision of the second bearing 27 can also effectively protect the guide rod 70, prevent the guide rod 70 from being damaged due to external force, and prolong the service life of the overturning assembly 300; on the other hand, the second bearing 27 can also bear the axial load, and improve the rotation accuracy of the guide rod 70.

[0078] The driving gear 23, the driven gear 24 and the transmission gear 25 are rotatably mounted on the mounting base 10. Specifically, the mounting base 10 comprises a mounting plate 11 and a mounting shell 12. The mounting plate 11 is fixedly connected with the mounting shell 12. The driving gear 23, the driven gear 24 and the transmission gear 25 are rotatably mounted on the mounting plate 11, thereby facilitating the assembly of the driving gear 23, the driven gear 24 and the transmission gear 25 with the mounting plate 11. Of course, in some embodiments, at least one of the driving gear 23, the driven gear 24 and the transmission gear 25 can also be rotatably mounted on the mounting shell 12, and the embodiments of the utility model are not limited in particular. The driving gear 23 is arranged between the mounting plate 11 and the mounting shell 12, the driving part 21 is arranged on the side of the mounting shell 12 away from the mounting plate 11 and is fixedly connected with the driving gear 23, thereby facilitating the maintenance, replacement and other operations of the driving member 20. The transmission part 22 and the guide rod 70 each pass through the mounting shell 12 and are fixed on the mounting plate 11, thereby facilitating the assembly of each part of the overturning assembly 300, and the structure is simple and compact.

[0079] In some embodiments, the overturning assembly 300 further comprises a limiting seat 30, and in the height direction Y of the overturning assembly 300, the sliding member 40 is arranged between the limiting seat 30 and the mounting base 10. In this way, the limiting seat 30 can limit the sliding range of the sliding member 40, and avoid the problem that the sliding distance of the sliding member 40 exceeds the preset distance and causes damage to the overturning assembly 300 and the grass collecting box 200. In this embodiment, when the sliding member 40 is stopped by the limiting seat 30, the swing rod 50 is located at the first limit position P1, and the grass collecting box 200 is closed on the machine body 100. The limiting seat 30 is mounted on the machine body 100. In this embodiment, one end of the transmission part 22 is mounted on the mounting base 10, and the other end of the transmission part 22 is mounted on the limiting seat 30, thereby improving the reliability and stability of the connection between the transmission part 22 and the limiting seat 30 and the mounting base 10. Of course, in some embodiments, the limiting seat 30 can also be omitted.

[0080] In some embodiments, the overturning assembly 300 further comprises a guide rod 70, which is mounted on the mounting seat 10 and / or the limiting seat 30, and the sliding piece 40 is provided with a guide hole 405 which is in sliding cooperation with the guide rod 70, and the extension direction of the guide rod 70 is parallel to the height direction Y of the overturning assembly 300. Thus, based on the provision of the guide rod 70, the guide rod 70 can guide the sliding of the sliding piece 40, and can bear the force applied to the sliding piece 40 and the driving piece 20 by the swing rod 50, thereby improving the stability and reliability of the sliding of the sliding piece 40, and prolonging the service life of the overturning assembly 300. Exemplarily, in the present embodiment, two guide rods 70 are provided, one end of each guide rod 70 is connected to the mounting seat 10, and the other end is connected to the limiting seat 30, and the transmission part 22 is arranged between the two guide rods 70, so that the sliding piece 40 is uniformly stressed at both ends in the length direction X of the overturning assembly 300, thereby improving the stability and reliability of the movement of the sliding piece 40 and the swing rod 50, and prolonging the service life of the overturning assembly 300. It should be noted that the number of guide rods 70 is only used for illustration, and the guide rod 70 can also be provided as one or more than two, and the present embodiment is not limited specifically.

[0081] In the present embodiment, the driving piece 20 further comprises a transmission gear 25, which is connected with the guide rod 70 and is in meshing cooperation with the driving gear 23 and the driven gear 24, so as to transmit the driving force output by the driving part 21 to the transmission part 22. Thus, the overall structure of the overturning assembly 300 is more compact, and the combination of the three gears of the driving gear 23, the driven gear 24 and the transmission gear 25 can improve the transmission efficiency. The transmission gear 25 can be fixedly connected with the guide rod 70 and rotatably connected with the mounting seat 10; or the transmission gear 25 is rotatably connected with the guide rod 70 and fixedly connected with the mounting seat 10. Of course, in some embodiments, the transmission gear 25 can be arranged to avoid the guide rod 70 and rotatably mounted on the mounting seat 10; or the transmission gear 25 can be omitted, and the guide rod 70 is arranged to avoid the driving gear 23 and the driven gear 24.

[0082] Please refer to Figure 4 , Figure 7 and Figure 8When the grass collecting box 200 is in the grass collecting state, the end of the swing bar 50 connected with the rolling bearing 61 swings to the first end 4021 of the sliding groove 402, the sliding piece 40 is located at the end of the transmission part 22 away from the mounting base 10, the grass collecting box 200 is covered on the machine body 100, and the grass is collected. When the grass collecting box 200 is full of grass and the grass is unloaded, the driving part 21 controls the transmission part 22 to rotate in the positive direction, the rotation of the transmission part 22 drives the sliding piece 40 to slide towards the side close to the mounting base 10, the sliding of the sliding piece 40 drives the rolling bearing 61 to slide in the sliding groove 402 towards the second end 4022, so that the swing bar 50 swings around the rotation axis 221 of the rotation axis 220 and the grass collecting box 200 is flipped around the rotation axis 221 towards the side close to the grass collecting box 200. Thus, the torque force F exerted by the sliding piece 40 on the swing bar 50 is along the tangent direction of the swing trajectory 505 of the swing bar 50, which improves the utilization rate of the driving force output by the driving part 20, so that the flipping assembly 300 saves time and labor in the process of flipping the grass collecting box 200. When the end of the swing bar 50 connected with the rolling bearing 61 swings to the second end 4022 of the sliding groove 402, the sliding piece 40 is located at the end of the transmission part 22 close to the mounting base 10, and the flipping angle of the grass collecting box 200 relative to the machine body 100 is 80°, so that the grass in the grass collecting box 200 is inclined out of the grass collecting box 200 under the action of gravity. It can be understood that when the amount of grass in the grass collecting box 200 is small or the size of the grass collecting box 200 is small, the end of the swing bar 50 connected with the rolling bearing 61 can swing to a preset position between the first end 4021 and the second end 4022 of the sliding groove 402, that is, the flipping angle of the grass collecting box 200 relative to the machine body 100 can be less than 80°. In addition, since the swing bar 50 swings along the tangent direction of the swing trajectory 505, the swing bar 50 and the sliding piece 40 form a labor-saving similar crank slider mechanism. Therefore, the swing bar 50 is not limited by the length, even if it is less than the center moment of the rear grass collecting box 200, and the torque is constant, which is the best state of the flipping mechanism to save labor.

[0083] After the unloading operation is completed, the end of the swing lever 50 connected with the rolling bearing 61 needs to be reset to the first end 4021 of the sliding groove 402. At this time, the driving part 21 controls the transmission part 22 to rotate in the opposite direction, the rotation of the transmission part 22 drives the sliding part 40 to slide away from the mounting base 10, and the sliding of the sliding part 40 drives the rolling bearing 61 to slide in the sliding groove 402 towards the first end 4021, so that the swing lever 50 rotates around the rotation axis 221 of the rotation shaft 220 and the hay collector 200 is flipped away from the side of the hay collector 200 around the rotation axis 221. When the end of the swing lever 50 connected with the rolling bearing 61 swings to the second end 4022 of the sliding groove 402, the driving part 21 is controlled to stop working. Since the sliding groove 402 is inclined upward relative to the horizontal plane towards the side of the hay collector 200, the position of the swing lever 50 can always move in one direction when the swing lever 50 is pushed to swing, and cannot run to the other side to form resistance or cannot be reset, so that the swing lever 50 is also in a labor-saving state when being reset.

[0084] The above is only a specific implementation manner of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.​
