[0030] In this embodiment, a plurality of pruning knives 5 are arranged on the pruning knife disc 2, the blade side 6 of the pruning knives 5 has an arc, the back side 7 of the pruning knives 5 is in a straight line, and the width of the pruning knives 5 changes from the fixed end of the pruning knives 5 to the free end of the pruning knives 5 along the curve (i.e., the distance between the blade side 6 of the pruning knives 5 and the back side 7 of the corresponding position) as follows: first decreases, then increases, and then decreases again. The pruning knives 5 of this embodiment are strengthened in the middle part, and at the same time, the risk of the blade side 6 of the pruning knives 5 being damaged by lawn gravel, coarse wood and grass roots is reduced by cooperating with the gravel fork 22 arranged at the front part of the vehicle body 1; one side of the pruning knives 5 is a plane, and the other side of the pruning knives 5 is a curved surface, and the thickness of the pruning knives 5 changes from the back side 7 of the pruning knives 5 to the blade side 6 of the pruning knives 5 along the curve (i.e., the distance between the curved surface of the pruning knives 5 and the flat surface at the corresponding position) as follows: first increases, then decreases, and the curved surface shape of the pruning knives 5 is similar to the streamline shape of a propeller. This embodiment adopts the pruning knife 5 of the above shape, so that when the pruning knife 5 is mowing, the air flow can be increased, the suction force of the mowing cover 31 can be increased, the grass residue can be introduced into the collection and compression structure, and the cutting efficiency is increased.

[0031] In this embodiment, the collecting and compressing structure includes a collecting and compressing shell 8, and an openable inspection door 21 is provided on the collecting and compressing shell. The collecting and compressing shell 8 includes a collecting bin 9 and a compression bin 10. A partition 11 is provided between the collecting bin 9 and the compression bin 10. The partition 11 is arranged at an angle. One end of the partition 11 is connected to the collecting and compressing shell 8, and the other end of the partition 11 is provided with a guide plate 12. One end of the guide plate 12 is hinged to the other end of the partition 11, and the guide plate 12 is located in the compression bin 10. A connecting port between the collecting bin 9 and the mowing structure is formed between the other end of the partition 11 and the collecting and compressing shell 8, and a buffer grille 13 is provided at the connecting port. A rotatable grass rolling component is provided in the collecting bin 9, and the grass rolling component includes a rotating shaft 14 and a plurality of grass rolling teeth 15. The rotating shaft 14 is rotatably connected to the collecting and compressing shell 8, and the plurality of grass rolling teeth 15 are arranged on the rotating shaft 14. The compression component is located in the compression bin 10.

[0032] In this embodiment, the compression assembly includes a compression plate 20, and a gate 16 is provided on the collecting and compressing shell. The gate 16 corresponds to the compression chamber 10, and the compression plate 20 can move in a straight line and compress the grass 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, and the battery pack 17 is located at the front part of the vehicle body 1. The battery pack 17 is preferably a lithium iron phosphate battery. The first drive structure 18 of the lawn mower, the second drive structure of the lawn mower structure 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, which is located at the front part of the vehicle body 1. The first drive structure 18 is used to drive the lawn mower to move. The second drive structure is a motor, which is located in the mowing cover 31 and is used to drive the pruning disc 2 to rotate to achieve mowing. The third drive structure 19 is an electric telescopic rod, which is located in the compression chamber 10, and 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 compression of grass residues.

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

[0035] When the lawn mower of this embodiment is working, as the body 1 moves forward, the mowing structure realizes mowing and guides the grass residue into the collecting bin 9. The grass residue first passes through the grass rolling component and pushes the grass rolling component to rotate. Under the action of the grass rolling component, it is decelerated and falls into the compression bin 10 after passing through the buffer grille 13. When the grass residue reaches a certain amount, the third driving structure 19 is started. The third driving structure 19 drives the compression plate 20 to push the grass residue in the direction of the gate 16 every 2 minutes. The tail of the compression bin 10 is in the shape of a rectangular parallelepiped. After continuous pushing and squeezing by the compression plate 20, the grass residue is compressed and compacted at the tail of the compression bin 10. The gate 16 is closed during the compression process. When the movement position of the compression plate 20 is located in front of the corresponding position of the buffer grille 13, the instrument panel of the body 1 lights up, prompting the operator to open the gate 16 of the grass outlet after putting the net bag on the grass outlet. The compression plate 20 pushes the compressed grass residue blocks into the net bag to realize packaging and collection, and the grass residue is collected and transported manually.

[0036] The mowing vehicle of this embodiment integrates the mowing and grass residue compression functions. After mowing, the grass residue is directly combed and compressed in the compression chamber 10. On the one hand, the grass residue capacity is expanded, and at the same time, the compressed grass blocks are convenient for centralized cleaning, which solves the problems of low mowing efficiency and high labor input as a whole. At the same time, by adjusting the power source, the traditional gasoline engine is replaced with a high-energy storage battery pack 17 to drive the motor and the electric telescopic rod to generate power, and the electric energy is transmitted through the cable, so that the power structure can be arranged near the high-energy consumption parts such as the pruning shear disc 2 and the compression plate 20. Change the original series of problems such as using a single engine to generate power, using a power transmission rod to transmit power over a long distance, consuming a lot of energy in the power transmission process, or using a generator for secondary power generation, resulting in large energy losses and power devices occupying a large space in the vehicle body.

[0037] The lawn mower of this embodiment directly connects the outlet of the mowing structure with the collecting and compressing structure, so that the cut grass residue can be introduced into the compression bin 10, and the grass residue is compressed for easy collection, thereby realizing the expansion of grass residue storage and the compression of grass residue into blocks, solving the problem that the existing lawn mowers have a small collection volume and need to frequently stop to dump grass residues, as well as low mowing efficiency, and integrates the mowing and compression functions to achieve large-capacity storage of grass residues, reduce the frequency of stops, and reduce labor input; the gasoline drive is changed to electric drive to reduce energy consumption, and the drive structure is arranged separately according to the functional areas of the vehicle body 1, streamlining the space inside the vehicle, leaving the space inside the vehicle for the compression bin 10, and expanding the space for grass residue storage and compression; this embodiment adjusts the shape of the pruning knife 5, and cooperates with the gravel fork 22 to remove high-hardness objects such as gravel to prevent the risk of damaging the pruning knife 5.

[0038] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
