[0061] The following describes in detail exemplary embodiments of the present application, enabling those skilled in the art to readily implement various exemplary embodiments. Other features and performance can be readily understood by those skilled in the art based on the information disclosed herein. This application can be implemented by other embodiments or applied to other embodiments. Furthermore, the detailed description can be modified or altered according to viewpoint and application without departing from the scope, spirit, and other purposes of this application.

[0062] In the description of this specification, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that the specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0063] As mentioned above, for large-scale lawnmowers that use integrated grass collection bags to collect grass clippings, which require frequent manual dumping or loading for transport, this application provides a grass collection trailer 100 and a garden maintenance system 1000. By designing a grass collection box 110 with an independent box-type storage compartment A, the grass collection box 110 is supported on a chassis structure 120. The chassis structure 120 can be independently connected to the lawnmower 200 to hold the grass clippings cut by the lawnmower 200 during operation, thereby increasing the grass clippings collection capacity during the mowing process, avoiding frequent dumping and unloading, improving work efficiency, and reducing labor costs.

[0064] Furthermore, when unloading is required, the chassis structure 120 can be separated from the lawnmower 200 and then connected to the power vehicle 300. Under the traction of the power vehicle 300, the grass collection box 110 can be transferred to the unloading position for unloading, thus avoiding the need for secondary loading of materials after mowing, further reducing labor costs and improving work efficiency.

[0065] Based on the above, see Figures 1-9As exemplified, this application embodiment provides a grass collection trailer 100, including a grass collection box 110 with a storage bin A; a chassis structure 120 supporting the grass collection box 110, the chassis structure 120 being configured to be independently connected to a lawnmower 200 or a powered vehicle 300 and move under the traction of the lawnmower 200 or the powered vehicle 300; wherein, when the chassis structure 120 is connected to the lawnmower 100, the storage bin A can receive the material transported by the lawnmower 200.

[0066] It is understood that in this embodiment, the grass collection box 110 is supported on the top of the chassis structure 120. The chassis structure 120 can be connected independently to the lawnmower 200 or to the powered vehicle 300. For example, the chassis structure 120 can be adapted to different powered vehicles 300 such as the lawnmower 200 and the electric tractor through a ball joint traction device or a quick-connect pin mechanism to achieve quick switching between different traction mechanisms.

[0067] Furthermore, when the chassis structure 120 is connected to the lawnmower 200, the lawnmower 200 can be a large, ride-on lawnmower, such as a commercial zero-turn lawnmower or a tractor-mounted lawnmower. Its high mobility and high power characteristics can efficiently tow the hay collection trailer 100 and complete the hay clipping transportation, adapting to large-area garden operations. In addition, the storage bin A of the hay collection box 110 can be connected to the lawnmower 200 through corrugated pipes, flexible sleeves, and other pipe fittings. The lawnmower 200 uses a built-in hay collection fan to transport the shredded hay through these pipe fittings to the large-capacity storage bin A, thereby improving operating efficiency and reducing costs.

[0068] The function of the grass collection box 110 in this application embodiment is to collect materials such as grass and leaves. In order to enable the materials to enter the storage bin A, in some embodiments, the grass collection box 110 has an inlet B that connects to the storage bin A at least one end along the direction of travel. The inlet B can be connected to the lawnmower 200 through a hose to receive the materials transported by the lawnmower 200.

[0069] For example, the feed port B on the grass collection box 110 can be located at one end of the chassis structure 120 in the direction of connecting to the mower 200, or on one side of the chassis structure 120 in the direction of connecting to the mower 200; and the number of feed ports B can be one or more. The design of multiple feed ports B on the grass collection box 110 is more conducive to improving the feeding efficiency.

[0070] Accordingly, in order to enable the material to leave the storage bin A and complete the unloading, in some embodiments, the grass collection cart 110 has an unloading port C connected to the storage bin A at at least one end along the direction of travel. The unloading port C is equipped with an openable and closable door 114. When the door 114 is opened, the material in the storage bin A can leave the storage bin A through the unloading port C.

[0071] With the chassis structure 120 connected to the lawnmower 200 as the front end, the discharge port C on the grass collection box 110 can be located at the rear and front of the grass collection box 110, respectively, or both can be located at the front of the grass collection box 110. (Reference) Figure 2 As shown, when both the discharge port C and the feed port B are located at the front end of the hay collection box 110, the discharge port C can be located at the bottom of the feed port B in the height direction. The openable and closable box door 114 configured for the discharge port C can be a single-leaf flip-type door (for example, the box door 114 is connected to the edge of the discharge port C by a hinge on the top or side, and flips outward when opened), or it can be a double-leaf door (for example, it consists of two box doors on the left and right, which open to both sides by vertical hinges to form the maximum opening width). The box door 114 can be opened and closed by a mechanical lock. For example, a rotating handle is provided on the outside of the lock box door 114. The rotating handle is connected to a connecting rod, and the connecting rod drives the locking tongue to insert into the locking groove of the frame of the discharge port C to achieve mechanical locking.

[0072] refer to Figure 2 and Figure 3 As shown, to facilitate observation of the filling status inside the storage bin A, in some embodiments, the hay collection cart 110 includes a frame body 111, a first enclosure 112, and a second enclosure 113; the frame body 111 encloses a storage space; the first enclosure 112 and the second enclosure 113 are respectively disposed on the frame body 111 and each covers at least a portion of the storage space to enclose the storage space into the storage bin A; wherein, the first enclosure 112 is higher than the second enclosure 113 in the height direction, and the first enclosure 112 can expose the filling status inside the storage bin A.

[0073] refer to Figure 4 As an example, the frame body 111 can be composed of an upper frame, a lower frame, and several support columns. The upper and lower frames are arranged at intervals along the height direction, and the multiple support columns are arranged at intervals between the upper and lower frames. The upper and lower ends of each support column are connected to the upper and lower frames respectively, forming a cuboid frame structure to enclose the storage space. The first enclosure 112 can cover the upper frame and the support columns near the upper frame, and the second enclosure 113 can cover the lower frame and the support columns near the lower frame. The bottom of the first enclosure 112 on the support column can be fixedly connected to the top of the second enclosure 113, so that the first enclosure 112 is higher than the second enclosure 113 in the height direction.

[0074] The first enclosure 112 can expose the filling status inside the storage bin A. According to the example of the embodiment of this application, the first enclosure 112 can be a mesh, acrylic sheet or tempered glass sheet, so that the material storage volume inside the storage bin A can be seen through the first enclosure 112. The second enclosure 113 mainly bears the material load inside the storage bin A and should have high strength, specifically it can be stainless steel sheet.

[0075] In one specific embodiment, the top of the frame body 111 is completely covered by the first enclosure 112, the bottom is completely covered by the second enclosure 113, the left and right sides are completely covered by the first enclosure 112 and the second enclosure 113, the bottom of the front end of the frame body 111 is completely covered by the second enclosure 113, and an open feed port B is provided at the top of the front end, that is, the first enclosure 112 may not be designed at the top of the front end of the frame body 111. The rear end of the frame body 111 is designed with a discharge port C and a box door 114. Of course, in some embodiments, when the feed port B is located at the top of the front end of the frame body 111, the first enclosure 112 may also be covered at the top of the front end of the frame body 111, and the feed port B may be opened on the first enclosure 112.

[0076] To guide materials into storage silo A, in some embodiments, the hay collecting trailer 100 also includes a conveying hose 130. The conveying hose 130 can be a corrugated hose or a retractable hose. One end of the conveying hose 130 can be detachably connected to the feed inlet B via a clamp flange or a rotary locking connector, or it can extend directly into storage silo A through the feed inlet B. In short, the connection between the conveying hose 130 and the hay collecting trailer 100 is detachable, so that the conveying hose 130 can be disassembled when transferring materials within the hay collecting trailer 100. The other end of the conveying hose 130 is used to connect to the lawnmower 200 to receive the materials conveyed by the lawnmower 200. For example, the hay collecting fan inside the lawnmower 200 can generate negative pressure to convey the hay along the conveying hose 130 into storage silo A.

[0077] refer to Figure 5 In some embodiments, when the mower 200 is not equipped with a grass-collecting fan or the grass-collecting trailer 100 is connected to a powered vehicle, the grass-collecting trailer 100 also includes a material-collecting fan 140. The material-collecting fan 140 is installed on and connected to the material-collecting hose 130. The material-collecting fan 140 can generate negative pressure in the material-collecting hose 130 to transport external materials through the material-collecting hose 130 to the storage bin A.

[0078] It should be noted that in some embodiments, when the grass collection trailer 100 is connected to the powered vehicle 300, the material conveying hose 130 can directly use the collection fan 140 to generate negative pressure to adsorb leaves or other waste materials on the ground. That is, the grass collection trailer 100 can not only be connected to the lawnmower 200 to collect grass, but can also be directly connected to the powered vehicle 300 to achieve multi-functional sanitation operations, so as to take into account the application needs of mowing and environmental cleaning.

[0079] refer to Figure 6Traditional transport vehicles lack efficient self-unloading devices, and dumping hay clippings requires additional equipment or manual operation, increasing time and labor costs. Therefore, in some embodiments, the chassis structure 120 includes a chassis body 121 and a hydraulic self-unloading device 122. The chassis body 121 is connected to the hay collection box 110, and a trailer arm is provided on the chassis body 121 for movably connecting with the lawnmower 200 or the powered vehicle 300. The hydraulic self-unloading device 122 is located inside the chassis body 121, connected to the bottom of the hay collection box 110 and can be linked with the hay collection box 110 to lift the hay collection box 110 for tilting unloading.

[0080] In this embodiment, the unloading port B can be designed at the rear end of the grass collection box 110. The chassis body 121 can be composed of a main frame 1211, a sub-frame 1212, and a set of wheels 1213 or tracks. The set of wheels 1213 or tracks are connected to the main frame 1211 to move under the traction of the lawnmower 200 or the powered vehicle 300. The trailer arm 1214 is located at the front end of the main frame 1211, and the rear end of the sub-frame 1212 is connected to the top of the main frame 1211. The subframe 1212 is hinged at the end and fixedly connected to the top of the hay collection box 110. The hydraulic self-unloading device 122 is arranged inside the main frame 1211 and connected to the bottom of the hay collection box 110. During unloading, the hydraulic self-unloading device 122 lifts the hay collection box 110, and the rear end of the subframe 1212 rotates based on the main frame 1211, thereby causing the hay collection box 110 to tilt so that the hay can be unloaded from the unloading port B, thereby saving unloading time and labor costs.

[0081] Furthermore, the hydraulic self-unloading device 122 includes a drive motor 1221, a hydraulic cylinder 1222, a hydraulic pump 1223, and a lifting piston rod 1224; the hydraulic cylinder 1222 is installed inside the chassis body 121 and is connected to the hydraulic pump 1223 through a high-pressure pipeline; one end of the lifting piston rod 1224 is connected to the hydraulic cylinder 1222, and the other end is used to lift the bottom of the grass collection box 110; the drive motor 1221 is connected to the hydraulic pump 1223, and the hydraulic pump 1223 can drive the hydraulic cylinder 1222 to drive the lifting piston rod 1224 to lift one end of the grass collection box 110 under the drive of the drive motor 1221, so that the grass collection box 110 is tilted to the target angle.

[0082] In this embodiment, the drive motor 1221, hydraulic cylinder 1222, hydraulic pump 1223 and lifting piston rod 1224 are all located within the receiving space enclosed by the main frame 1211. The drive motor 1221 and hydraulic pump 1223 are connected and arranged together at the rear end of the trailer arm 1214. The hydraulic cylinder 1222 and hydraulic pump 1223 are arranged at intervals in the front-rear direction and connected by pipes. The lifting piston rod 1224 is connected to the hydraulic cylinder 1222. The end of the lifting piston rod 1224 away from the hydraulic cylinder 1222 is connected to the bottom of the sub-frame 1212 or directly connected to the bottom of the hay collection box 110.

[0083] It should be understood that the drive motor 1221 in this embodiment can be powered by the power vehicle 300, and the target angle of the grass collection box 110 can be any angle value in the range of 0 to 70°. For example, the grass collection box 110 can be tilted to 55° for unloading.

[0084] During unloading, the drive motor 1221 drives the hydraulic pump 1223 to supply oil to the hydraulic cylinder 1222, the piston rod 1224 extends, the sub-frame 1212 rotates around the axis, and the front end of the grass collection box 110 is raised so that the grass collection box 110 is tilted to the target angle, and the material is released from the grass collection box 110, thereby improving the material transfer efficiency and reducing costs.

[0085] Another embodiment of this application provides a garden maintenance system 1000, including the grass collection trailer 100 as described above, a connecting component 400, a lawnmower 200, and a powered vehicle 300; the connecting component 400 includes a connector 410 and a mating component 420, the connector 410 being mounted on the lawnmower 200 or the powered vehicle 300, and the mating component 420 being mounted on the chassis structure 120; wherein the connector 410 and the mating component 420 can be quickly locked or separated.

[0086] refer to Figure 7 In this embodiment, the grass-collecting trailer 100 achieves rapid locking or disengagement from the lawnmower 200 or the powered vehicle 300 via a connecting assembly 400. The connecting assembly 400 mainly consists of a connector 410 and a mating component 420. The connector 410 is mounted on the lawnmower 200 or the powered vehicle 300 and can be a trailer ring, trailer hook, or trailer ball joint. The mating component 420 is mounted on the trailer arm 1214 of the chassis structure 120 and can be adapted to connect with the connector 410. Specifically, it can be a universal adapter and safety chain, quick-release buckle, or automatic locking ball cover to achieve rapid locking or disengagement of the connector 410 and the mating component 420.

[0087] To adapt to complex terrain conditions and overcome the lack of stability in the coordinated operation of trailers and lawnmowers, in some embodiments, when the connector 410 and the mating part 420 are locked, a clearance is reserved between the connector 410 and the mating part 420 to allow the grass-collecting trailer 100 to move relative to the lawnmower 200 or the powered vehicle 300. That is, the grass-collecting trailer 100 can be movably connected with the lawnmower 200 or the powered vehicle 300 to autonomously adjust its posture to maintain a horizontal position on bumpy road sections, avoid stress concentration in rigid connections caused by terrain undulations, and effectively prevent structural damage.

[0088] refer to Figures 7-9In some embodiments, the connector 410 is a ball head; the mating member 420 includes: a ball cover 421, on which a movable locking groove adapted to the ball head is formed, and the ball head is allowed to move within the movable locking groove; a locking pin 422, disposed on one side of the movable locking groove; and a handle 423, disposed on the ball cover 421 and connected to the locking pin 422, for driving the locking pin 422 into or out of the movable locking groove to lock or separate the ball head within the movable locking groove.

[0089] In this embodiment, the locking pin 422 is rotatably connected to one side of the movable locking groove, and a first spring 424 is arranged between the top of the locking pin 422 and the ball cover 421, and a second spring 425 is arranged at the bottom of the locking pin 422. A connecting nut 426 is provided at the bottom of the second spring 425. The handle 423 is located on the top of the ball cover 421 and passes through the ball cover 421, the first spring 424, the locking pin 422 and the second spring 425 in sequence along the height direction and is connected to the connecting nut 426. When the handle 423 is moved in the front and back direction, the locking pin 422 can rotate into or out of the movable locking groove (for example, when the handle 423 is pressed down, the locking pin 422 is inserted into the movable locking groove, and when it is lifted up, it is unlocked), so as to lock or separate the ball head connector 410 in the movable locking groove. When operating in rugged terrain, the ball head can swing slightly in the ball cover 421 to avoid structural stress concentration caused by rigid connection.

[0090] The connecting assembly 400, consisting of the ball head, locking pin 422, ball cover 421, and other parts mentioned above, is only an example. In some embodiments not shown, the connecting assembly 400 may be a rod with a positioning hole at the end and a U-shaped cast steel bracket (with a spring-loaded locking pin on the inside) and a locking seat. When the rod is connected to the locking seat, the locking pin automatically springs into the positioning hole and locks after the rod is inserted into the locking seat. Alternatively, the connecting assembly 400 may be a cross shaft and a double-ear bracket. The double-ear bracket has a swing support with a bushing to provide multi-degree-of-freedom compensation when connecting the cross shaft, thus avoiding structural stress concentration caused by rigid connection.

[0091] In summary, the design of the grass collection trailer 100 and the garden maintenance system 1000 provided in this application embodiment enables continuous operation for a long period of time without frequent interruptions for manual dumping or loading and transfer, effectively improving work efficiency and significantly reducing labor costs, thus meeting the needs of modern garden management.

[0092] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
