[0047] The technical solution of this application will now be described in detail with reference to the accompanying drawings and embodiments.

[0048] According to one aspect of this application, a mowing device is provided, comprising: a main body 1, an opening and closing part 2, and a driving part 6, wherein the main body 1 has a cavity for accommodating weeds, the front end 11 of the main body 1 has an opening for weeds to enter, the opening and closing part 2 is closably mounted on the front end 11 to open or close the opening, the driving part 6 is capable of controlling the opening and closing of the opening and closing part 2, and at least one of the front end 11 and the opening and closing part 2 is equipped with a cutting element for cutting the weeds when the opening and closing part 2 is closed.

[0049] According to this technical solution, such as Figure 1 and 2 As shown, the opening / closing part 2 matches the opening of the main body 1. The opening / closing part 2 can be controlled to open or close by the driving part 6. The driving part 6 can control the opening / closing of the opening / closing part 2 by various means such as a motor or hydraulic rod. When the opening / closing part 2 is open, weeds enter the cavity of the main body 1 through the opening. The cutting element can be in the form of a sharp blade and can be installed at the opening of the front end 11 or at the front end of the opening / closing part 2. Through the cooperation between the opening / closing part 2 and the front end 11, the cutting element can cut the weeds in the cavity during the opening and closing process. The cut weeds are kept in the cavity and can be transported to the storage part for storing weeds by a conveying device.

[0050] With this technical solution, the weeds are cut and enter the cavity of the main body 1, and can be transported to the storage area by other conveying devices, which avoids the weeds falling on the lawn, replaces the drawback of traditional lawnmowers cutting grass with a blade disc and causing weeds to scatter, and replaces the high-speed rotating blade disc, reducing safety hazards.

[0051] To facilitate the entry of weeds into the cavity for more efficient weed cutting, according to a preferred embodiment, a collecting mechanism 5 is provided inside the main body 1. When the opening and closing part 2 is open, the collecting mechanism 5 extends out from the front end 11, and when the opening and closing part 2 is closed, the collecting mechanism 5 retracts into the cavity of the main body 1. The collecting mechanism 5 is used to collect weeds into the cavity of the main body 1. Through this technical solution, the collecting mechanism 5 can gather more weeds located near the front end 11 and collect them into the cavity. When the opening and closing part 2 is closed, the collecting mechanism 5 can keep the gathered weeds inside the cavity, preventing some weeds from overflowing out of the cavity due to the squeezing of the weeds when the opening and closing part 2 is closed.

[0052] The collection mechanism 5 can take a suitable form to facilitate the collection of weeds, according to a preferred embodiment of this application, such as... Figure 3 As shown, the collecting mechanism 5 includes a bent end 51 and a rotating part 52 rotatably connected to the front end 11. Rotation of the rotating part 52 allows the collecting mechanism 5 to extend from or retract into the cavity of the main body 1. With this technical solution, the collecting mechanism 5 is installed inside the front end 11 via the rotating part. The end 51 of the collecting mechanism 5 can extend out of the opening via the rotation of the rotating part 52. The end 51 can be bent along the rotation direction when collecting weeds, thereby collecting weeds near the front end 11 into the cavity and preventing the collected weeds from overflowing from the cavity. Specifically, the collecting mechanism 5 may include a rod-shaped body, which can rotate in a plane via the rotating part 52, with the end 51 bending in the plane from the end of the rod-shaped body.

[0053] To prevent the collecting mechanism 5 from blocking the opening and closing part 2 during the weed-gathering process, thus preventing the opening and closing part 2 from closing and thus hindering weed cutting, in a preferred embodiment, the collecting mechanism 5 moves synchronously with the opening and closing part 2. This allows the collecting mechanism 5 to extend out of the main body 1 when the opening and closing part 2 opens, and to retract into the main body 1 when the opening and closing part 2 closes. With this technical solution, when the weeds are gathered into the cavity, the collecting mechanism 5 also remains within the cavity. At this time, the opening and closing part 2 can be completely closed, avoiding the problem that the opening and closing part 2 cannot close due to the collecting mechanism 5 being outside the opening, thus preventing the cutting element from cutting the weeds.

[0054] To synchronize the movement of the collecting mechanism 5 with the opening / closing part 2, according to a preferred embodiment, the driving part 6 includes a rotary driver 61 and a transmission mechanism that drives the rotary driver 61 and the collecting mechanism 5. This allows the rotary driver 61 to drive the opening / closing part 2 to open or close while simultaneously causing the collecting mechanism 5 to extend out of or retract into the main body 1. In this technical solution, the transmission mechanism can drive the rotary driver 61 and the rotating part 52 of the collecting mechanism 5, so that while the rotary driver 61 drives the opening / closing part 2 to open or close, the transmission mechanism simultaneously causes the collecting mechanism 5 to extend or retract. The transmission mechanism can directly transmit rotational torque or convert rotation into other motion modes for transmission, for example, through a drive shaft, hydraulic pipe, etc. No limitation is imposed here.

[0055] The transmission mechanism can take a suitable form to enable the collecting mechanism 5 to move synchronously with the opening and closing part 2. According to a preferred embodiment, such as... Figure 3 As shown, the transmission mechanism includes a first pulley 62, a first transmission member 64, and a second transmission member 65 mounted on the rotating shaft of the rotary driver 61. The first transmission member 64 includes a first rotating shaft with a first bevel gear at one end and a second pulley at the other end. The second transmission member 65 includes a second rotating shaft with a second bevel gear at one end and a third pulley at the other end. The first rotating shaft is parallel to the axis of the rotating shaft of the driver 61 and perpendicular to the axis of the second rotating shaft. The first bevel gear meshes with the second bevel gear. The first pulley 62 is connected to the second pulley via a first transmission belt 63. The third pulley is connected to the rotating part 52 via a second transmission belt 66.

[0056] In this technical solution, when the rotary driver 61 controls the opening and closing of the opening and closing part 2, the rotating shaft of the rotary driver 61 begins to rotate. Simultaneously, the rotating shaft of the rotary driver 61 drives the first pulley 62 to rotate, which in turn drives the second pulley of the first transmission component 64 to rotate via the first transmission belt 63. The first bevel gear rotates synchronously via the first rotating shaft. Since the first bevel gear meshes with the second bevel gear, the second bevel gear rotates in the opposite direction to the first bevel gear. The second rotating shaft of the second transmission component 65 drives the third pulley to rotate, and the second transmission belt 66 connected to the third pulley drives the rotating part 52 of the collecting mechanism 5 to rotate. This causes the collecting mechanism 5 to rotate to control the end 51 to extend out of the main body 1 and retract into the main body 1. By adjusting the angles and positions of the components in the above-mentioned transmission mechanism, synchronous movement of the opening and closing part 2 and the collecting mechanism 5 can be achieved. That is, when the opening and closing part 2 opens, the collecting mechanism 5 extends out of the main body 1; when the opening and closing part 2 closes, the collecting mechanism 5 retracts into the main body 1.

[0057] To prevent some weeds from remaining in the cavity of the main body 1 after cutting due to obstruction by the collecting mechanism 5 and the rotary drive 61, thus preventing them from entering the conveying device, in a preferred embodiment, the main body 1 and the opening / closing part 2 form a mouth shape, with the opening / closing part 2 forming the lower part of the mouth. The rotary drive 61 is located on the lower side of the mouth, and the second transmission member 65 is located on the upper part of the cavity of the main body 1. With this technical solution, the rotary drive 61 is located outside the cavity, the cavity opening is located at the lower part of the front end 11, and the collecting mechanism 5 is installed in the upper region of the front end 11. Therefore, the bottom of the cavity of the main body 1 used to accommodate weeds is free of any obstructions, allowing the weeds to smoothly pass through the connecting end 12 connected to the conveying device and enter the conveying device, avoiding the retention of weeds due to excessive obstruction of the cavity's transport.

[0058] The connection between the opening / closing part 2 and the main body 1 can take an appropriate form, according to a preferred embodiment, such as... Figure 1 and 2 As shown, the lawnmower includes a first connecting rod 3 and a second connecting rod 4 fixedly connected to the opening / closing part 2. The rotary drive 61 has a crankshaft 37 on its rotating shaft. The two ends of the first connecting rod 3 are respectively hinged to the main body 1 and the opening / closing part 2, and the second connecting rod 4 is hinged to the crankshaft 37. Through this technical solution, the opening / closing part 2 is hinged to the main body 1 via the first connecting rod 3, allowing the first connecting rod 3 to rotate around its junction with the main body. The opening / closing part 2 can also rotate around its junction with the first connecting rod 3. Furthermore, the second connecting rod 4, fixed to the opening / closing part 2, is hinged to the crankshaft 37. The crankshaft 37 restricts the movement of the opening / closing part 2. In other words, due to the combined action of the first connecting rod 3 and the second connecting rod 4, the position of the crankshaft 37 restricts the position of the opening / closing part 2. By rotating the crankshaft 37, the opening / closing part 2 can be controlled to move along a specific trajectory to achieve opening and closing.

[0059] To ensure stable movement of the opening / closing part 2, according to a preferred embodiment, first pins 17 for hinged connection of the first connecting rod 3 are symmetrically arranged on both outer sides of the main body 1, and second pins 27 for hinged connection of the first connecting rod 3 are symmetrically arranged on both outer sides of the opening / closing part 2. One end of the second connecting rod 4 is fixed to the second pin 27. Two crankshafts 37 are included, respectively mounted at both ends of the rotating shaft of the rotary drive 61. With this technical solution, the first connecting rod 3, the second connecting rod 4, and the crankshaft 37 are symmetrically arranged on both sides of the main body 1 and the opening / closing part 2. When the opening / closing part 2 moves, the two sets of connecting rod mechanisms jointly support the opening / closing part 2, improving its stability.

[0060] According to another aspect of this application, a lawn mowing robot is also provided, including a conveying device 200 for transporting weeds, a storage section 302 for storing weeds, a moving section 301, and the aforementioned mowing device. The storage section 302 and the conveying device 200 are mounted on the moving section 301, and the mowing device is mounted on the end of the conveying device 200. The cavity of the main body 1 is connected to the storage section 302 through the conveying device 200.

[0061] This technical solution allows the lawnmower robot to move to the location where weeds need to be cleared via the moving part 301, cut the weeds with the mowing device, and transport the cut weeds to the storage part 302 via the conveying device 200, thus completing the weed clearing. The conveying device 200 may include a transmission conduit 201, which is connected to the connecting end 12 of the main body 1, forming a path for transporting weeds between the cavity of the main body 1 and the transmission conduit 201. Furthermore, the lawnmower robot may include, for example, a suction device 303, to create negative pressure in the transmission conduit 201, thereby sucking the weeds from the main body 1 through the transmission conduit 201 into the storage part 302. Because the cavity of the main body 1 can collect the weeds, and the weeds are transported to the storage part via the conveying device 200, the weeds will not scatter on the ground during the entire process, avoiding the rework of cleaning up scattered weeds. Moreover, it replaces the high-speed rotating cutting disc of traditional lawnmowers, greatly reducing safety hazards during operation.

[0062] Lawn-mowing robots can be designed in the shape of animals to make the mowing process appear as if animals are grazing, increasing entertainment and visual appeal. For example, lawn-mowing robots can be designed as cows or hippos.
