Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] The purpose of this invention is to provide a lawnmower to solve the problems existing in the prior art, which can compress grass residue.

[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] like Figures 1 to 5 As shown, this embodiment provides a lawnmower, including: a vehicle body 1, a mowing structure, and a collection and compression structure. Both the mowing structure and the collection and compression structure are mounted on the vehicle body 1. The mowing structure cuts grass and guides the grass clippings into the collection and compression structure. The collection and compression structure includes a compression component, which compresses the grass clippings. In this embodiment, the mowing structure is located in front of the collection and compression structure. As the vehicle body 1 moves forward, the grass clippings cut by the mowing structure enter the collection and compression structure and are compressed by the compression component.

[0028] Specifically, in this embodiment, the vehicle body 1 is equipped with a steering wheel 23 and a driver's seat 24. The front of the vehicle body 1 is equipped with a front bumper 25 and a headlight 26. The chassis is located under the vehicle body 1. The vehicle body 1 is mounted on a frame 33. The frame 33 includes longitudinal steel beams 28, transverse steel beams 29, reinforcing beams 30, and a reinforcing frame 32. Longitudinal steel beams 28 are provided on both sides of the vehicle body 1. The front end of the longitudinal steel beams 28 extends to the front of the vehicle and connects with the front transverse steel beams 29. The rear end of the longitudinal steel beams 28 extends to the rear of the vehicle and connects with the rear transverse steel beams 29. A reinforcing beam 30 is provided in the middle of the longitudinal steel beams 28. A reinforcing frame 32 is provided at the rear of the frame 33. The reinforcing frame 32 facilitates the stress on the rear during compression.

[0029] This embodiment includes two parallel mowing structures. Multiple mowing structures can be set as needed. The mowing structures are suspended and connected to the vehicle body 1. The mowing structure includes a mowing cover 31 and a trimming disc 2. The bottom of the mowing cover 31 is provided with a support wheel 27. A grass-suction chamber 3 is formed inside the mowing cover 31. The trimming disc 2 is located at the grass-suction port 4 of the grass-suction chamber 3. The outlet of the grass-suction chamber 3 is connected to the collection and compression structure. The grass-suction chamber 3 gradually decreases in speed from the grass-suction port 4 to the outlet of the grass-suction chamber 3.

[0030] In this embodiment, a plurality of trimming scissors 5 are provided on the trimming scissors disc 2. The blade side 6 of the trimming scissors 5 is curved, and the back side 7 of the trimming scissors 5 is straight. The width of the trimming scissors 5 changes from the fixed end to the free end of the trimming scissors 5 (i.e., the distance between the blade side 6 of the trimming scissors 5 and the corresponding back side 7) according to the following rule: first decreases, then increases, and then decreases again. The trimming scissors 5 in this embodiment are reinforced in the middle. At the same time, in conjunction with the gravel fork 22 provided at the front of the vehicle body 1, the risk of the blade side 6 of the trimming scissors 5 being damaged by grass gravel, coarse wood roots and grass is reduced. One side of the trimming scissors 5 is flat, and the other side of the trimming scissors 5 is curved. The thickness of the trimming scissors 5 changes from the back side 7 to the blade side 6 of the trimming scissors 5 (i.e., the distance between the curved surface of the trimming scissors 5 and the corresponding flat surface) according to the following rule: first increases, then decreases. The curved surface shape of the trimming scissors 5 is similar to the streamlined shape of a propeller. In this embodiment, by using the above-described shape of the trimmer 5, the airflow can be increased when the trimmer 5 is cutting grass, and the suction of the grass-cutting cover 31 can be increased, so that the grass debris can be guided into the collection and compression structure, while increasing the cutting efficiency.

[0031] In this embodiment, the collection and compression structure includes a collection and compression housing 8, which is provided with an openable maintenance door 21. The collection and compression housing 8 includes a collection chamber 9 and a compression chamber 10. A partition 11 is provided between the collection chamber 9 and the compression chamber 10. The partition 11 is inclined and one end is connected to the collection and compression housing 8. A guide plate 12 is provided at the other end of the partition 11. One end of the guide plate 12 is hinged to the other end of the partition 11. The guide plate 12 is located in the compression chamber 10. The other end of the partition 11 and the collection and compression housing 8 form a communication port between the collection chamber 9 and the mowing structure. A buffer grid 13 is provided at the communication port. A rotatable grass-rolling assembly is provided in the collection chamber 9. The grass-rolling assembly includes a rotating shaft 14 and several grass-rolling teeth 15. The rotating shaft 14 is rotatably connected to the collection and compression housing 8. Several grass-rolling teeth 15 are provided on the rotating shaft 14. The compression assembly is located in the compression chamber 10.

[0032] In this embodiment, the compression assembly includes a compression plate 20, and a gate 16 is provided on the collection and compression shell. The gate 16 corresponds to the compression chamber 10. The compression plate 20 can move in a straight line and compress the straw residue between the compression plate 20 and the gate 16.

[0033] In this embodiment, a battery pack 17 is provided on the vehicle body 1. The battery pack 17 is located at the front of the vehicle body 1. The battery pack 17 is preferably a lithium iron phosphate battery. The first drive structure 18 of the lawnmower, the second drive structure of the lawnmower, and the third drive structure 19 of the compression assembly are all electrically connected to the battery pack 17. The first drive structure 18 is a motor located at the front of the vehicle body 1. The first drive structure 18 is used to drive the lawnmower to move. The second drive structure is a motor located inside the lawnmower cover 31 and is used to drive the trimmer disc 2 to rotate to achieve lawn mowing. The third drive structure 19 is an electric telescopic rod located inside the compression chamber 10. The telescopic end of the electric telescopic rod is connected to the compression plate 20. The third drive structure 19 is used to drive the compression plate 20 to perform linear motion to achieve the compression of grass residue.

[0034] In this embodiment, the first drive structure 18, the second drive structure, and the third drive structure 19 are all arranged close together to reduce the loss of power transmission energy.

[0035] In this embodiment, when the lawnmower is working, as the vehicle body 1 moves forward, the mowing structure mows the grass and guides the grass clippings into the collection chamber 9. The grass clippings first pass through the grass-rolling assembly and push the grass-rolling assembly to rotate. Under the action of the grass-rolling assembly, the grass clippings are decelerated and fall into the compression chamber 10 after passing through the buffer grid 13. When the grass clippings reach a certain amount, the third drive structure 19 is activated. The third drive structure 19 drives the compression plate 20 every 2 minutes to push the grass clippings towards the gate 16. The rear of the compression chamber 10 is rectangular. After the compression plate 20 pushes and squeezes continuously, the grass clippings are compressed and compacted at the rear of the compression chamber 10. During the compression process, the gate 16 is closed. When the movement position of the compression plate 20 is in front of the corresponding position of the buffer grid 13, the instrument panel light of the vehicle body 1 is lit, prompting the operator to put a net bag on the grass outlet and open the gate 16 of the grass outlet. The compression plate 20 pushes the compressed grass clippings into the net bag to achieve packaged collection, which is then collected and transported by the operator.

[0036] This embodiment of the lawnmower integrates mowing and grass clipping compression functions. After mowing, the grass clippings are directly combed and compressed in the compression chamber 10, which increases the grass clipping capacity and makes the compressed grass clumps easier to clean up, thus solving the problems of low mowing efficiency and high labor input. Furthermore, by adjusting the power source, replacing the traditional gasoline engine with a high-energy-storage battery pack 17 to drive the motor and electric telescopic pole, and transmitting electrical energy via cables, the power structure can be arranged closer to high-energy-consuming components such as the shear disc 2 and the compression plate 20. This changes the previous methods that relied on a single engine for power, used a long-distance force transmission rod for power transmission (resulting in high energy consumption during the transmission process), or used a generator for secondary power generation (resulting in significant energy loss and large space occupation of the power components).

[0037] This embodiment of the lawnmower directly connects the outlet of the mowing structure to the collection and compression structure. The cut grass clippings can be introduced into the compression chamber 10 for compression, making them easier to collect. This expands the storage capacity of grass clippings and compresses them into blocks, solving the problems of small collection capacity, frequent stops to dump grass clippings, and low mowing efficiency of existing lawnmowers. It integrates mowing and compression functions, achieving large-capacity grass clipping storage, reducing the frequency of stops, and reducing manual labor. By changing from gasoline drive to electric drive, energy consumption is reduced, and the drive structure is arranged separately according to the functional areas of the vehicle body 1, simplifying the interior space and leaving more space for the compression chamber 10, thus expanding the space for grass clipping storage and compression. This embodiment also adjusts the shape of the shears 5 and uses a stone-crushing fork 22 to remove high-hardness objects such as gravel, preventing the risk of damaging the shears 5.

[0038] Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
