[0035] Please refer to Figure 1 、 Figure 2 and Figure 5 , a first embodiment of the present utility model provides a cutting device 1, including a main body frame 13, a cutting device 11, a power device 14, and a lifting device 10 provided on the main body frame 13. The power device 14 is used to provide power, and the lifting device 10 is used to control the height of the cutting device 11. The lifting device 10 includes a tool holder 100. The cutting device 11 includes a support member 111 and a cutting tool 110. The support member 111 is used to mount the cutting tool 110 on the tool holder 100. The cutting tool 110 includes at least two blades 113; a plurality of cutting tools 110 are mounted on the tool holder 100, and the plurality of cutting tools 110 are arranged in a row.

[0036] The power device 14, i.e., the engine, includes but is not limited to diesel engines, gasoline engines, electric vehicle engines, or hybrid engines, etc.

[0037] Specifically, in some other embodiments, at least two cutting tools 110 are installed on the tool holder 100 for achieving large - range forage cutting and improving the cutting efficiency. The row - arrangement is mainly for achieving neat cutting of the forage during cutting.

[0038] Further, the cutting tools 110 are arranged in two rows, and the intervals between the cutting tools 110 in one row are arranged corresponding to the intervals between the cutting tools 110 in the other row.

[0039] It can be understood that, in order to prevent wear such as collision between the cutting tools 110 in the same row, there is a gap between the cutting tools 110 in the same row. As a result, during cutting, the forage in the gaps between the cutting tools 110 will not be cut, and the blade 113 needs to be translated repeatedly to achieve complete cutting. By setting two rows of cutting tools 110, when the cutting device 1 moves, the rear row can directly cut the forage that the front row has not cut, without the need for multiple translations of the blade 113, greatly saving working time and significantly improving efficiency.

[0040] Please combine Figure 2 and Figure 3 , specifically, the cutting tool 110 includes a fixing member 112 and a blade 113. The fixing member 112 is connected to the support member 111, the blade 113 is detachably connected to the fixing member 112, and the blade 113 can rotate relative to the support member 111.

[0041] In this embodiment, two blades 113 are provided on the cutting tool 110. The blade 113 is detachably installed on the fixing member 112, which is convenient for the operator to replace different blades 113 for cutting according to specific terrain and environmental characteristics. In addition, by setting two blades 113, the purpose of high - efficiency and fast cutting can be achieved. In addition, the blade 113 close to the support member 111 is defined as the first blade 113, and the other blade 113 is defined as the second blade 113. The diameter of the circle formed when the second blade 113 rotates is smaller than the diameter of the circle formed when the first blade 113 rotates; since the diameter of the second blade 113 during cutting rotation is smaller, especially for terrains with uneven ground, the second blade 113 can directly enter the sunken ground for cutting, greatly improving the usage environment limitations of the cutting device 1 and enabling it to be used in complex terrains.

[0042] In addition, since it is set to two blades 113, when the blades 113 rotate, each layer is cut separately. During actual use, as the cutting device 1 moves, since the diameter of the first blade 113 is larger, the first blade 113 contacts the forage first and cuts the upper layer of the forage, and the second blade 113 contacts the forage later and cuts the lower layer of the forage, directly cutting the grass into multiple segments. For the grass used for feed, the subsequent step of forage crushing can be directly reduced, and the harvesting efficiency is higher.

[0043] Furthermore, the blade 113 further includes a mounting portion 114 and at least two cutting portions 115. The cutting portion 115 is connected to or integrally formed with the mounting portion 114, and the mounting portion 114 is used to connect to the fixing member 112.

[0044] It can be understood that the cutting portion 115 can be understood as a part extending outward from the mounting portion 114. The blade 113 is not a traditional disc type. The gap between adjacent cutting portions 115 is beneficial for the forage to enter, achieving the purpose of rapid cutting. Since it is considered that the blade 113 will be worn after long-term use, therefore, the cutting portion 115 can also be selected as a separate part and installed on the mounting portion 114, achieving the purpose of only replacing the cutting portion 115 when the blade 113 is damaged, saving costs.

[0045] In some embodiments, the fixing member 112 can be set to be rotatable, then the blade 113 will directly follow the fixing member 112 to rotate. The fixing member 112 mainly plays a role of fixing the blade 113 and driving the blade 113 to rotate. Or the fixing member 112 can also be fixed on the support member 111, and the blade 113 is movably connected to the fixing member 112, realizing only the rotation of the blade 113.

[0046] Furthermore, the cutting portion 115 of at least one of the blades 113 is bent relative to the mounting portion 114.

[0047] It can be understood that the bent blade 113 can control the falling direction of the cut forage. During actual use, when the bent blade 113 rotates, it will form an inclined plane with the mounting portion 114, thereby guiding the cut forage to fall in the direction of the inclined plane, facilitating collection.

[0048] According to the specific actual situation, the cutting portion 115 of any blade 113 can be selected to be bent, or all of them can be bent, or neither of the two blades 113 can be bent.

[0049] As an optional implementation manner, the bending directions of two adjacent cutting portions 115 on the blade 113 are opposite.

[0050] Understandably, multiple cutting parts 115 can be provided on the blade 113 at the same time, including but not limited to 2, 3, 4, 6, 8, etc., without specific limitation. When the blade 113 has multiple cutting parts 115, the bending directions of two adjacent cutting parts 115 can be set to be opposite. In this way, when the blade 113 rotates, at least two cutting circles can be generated for cutting, so as to realize multi-segment shredding of forage. In a specific embodiment, the bending angle is not specifically limited.

[0051] Further, the rotation directions of the first blade 113 and the second blade 113 are the same or opposite.

[0052] As an alternative implementation manner, each blade 113 can be set to rotate independently; specifically, the different rotation directions of the blade 113 can be realized by the meshing between gears, and the specific setting method can be realized by using the existing technology, which will not be elaborated here.

[0053] Among them, for grass with better toughness, using two blades 113 with different rotation directions can cut more effectively.

[0054] Further, a driving device is provided in the support member 111. The fixing member 112 includes a central shaft 1121, the central shaft 1121 is connected to the driving device, an installation hole is provided at the center of the blade 113, the central shaft 1121 passes through the installation hole, and a connecting member 1122 is provided on the side of the second blade 113 away from the support member 111 and is detachably connected to the central shaft 1121.

[0055] The driving device can be an electric motor, etc., for driving the blade 113 to rotate. After the connecting member 1122 is connected to the central shaft 1121, the blade 113 is fixed to the fixing member 112. In a specific embodiment, a threaded hole can be provided at the end of the central shaft 1121, and the connecting member 1122 is a bolt. In addition, when disassembling and replacing the blade 113, only the connecting member 1122 needs to be removed, and then the two parts of the fixing member 112 can be disassembled to replace the blade 113.

[0056] Further, a groove 117 is formed between the cutting part 115 and the installation part 114 of the second blade 113, and the connecting member 1122 is located in the groove 117.

[0057] Understandably, the second blade 113 is provided with the groove 117 to accommodate the connecting member 1122. Thus, during use, the second blade 113 can directly cut the root of the grass, and the situation that the connecting member 1122 abuts against the ground and cannot cut the root will not occur.

[0058] As an alternative embodiment, the cutting portion 115 of the second blade 113 is arranged corresponding to the interval between the cutting portions 115 of the first blade 113.

[0059] Further, please refer to Figure 4 and Figure 5 , the lifting device 10 further includes a support arm 101 and a driving arm 102. One end of the support arm 101 is connected to the tool holder 100, and the other end is movably connected to the main body frame 13. One end of the driving arm 102 is connected with a wheel 12, and the driving arm 102 abuts against the support arm 101 to adjust the angle of the support arm 101.

[0060] It can be understood that the cutting tool 110 is installed on the tool rest, and the tool rest is connected to the main body frame 13 through the support arm 101. The tool rest moves up and down through the driving arm 102 to adjust the height of the cutting tool 110 thereon. Specifically, one end of the driving arm 102 is directly connected to the wheel 12. When the driving arm 102 drives the support arm 101 to lift upward, the force is mainly borne by the wheel 12, which has less impact on the vehicle frame. And since the driving arm 102 is not arranged at the bottom of the main body frame 13, it is not easily affected by complex terrains.

[0061] Further, in one of the embodiments, an abutting member 103 is arranged on the driving arm 102. The abutting member 103 is movably arranged on the driving arm 102, and the abutting member 103 is connected to the support arm 101.

[0062] It can be understood that in this embodiment, the driving arm 102 remains stationary, and the abutting member 103 on the driving arm 102 moves to adjust the angle of the support arm 101 and the height of the cutting tool 110. The abutting member 103 can be a movable step arranged on the side of the driving arm 102, or the abutting member 103 is arranged inside the driving arm 102 and forms a telescopic structure with the driving arm 102 where the abutting member 103 can extend out from the inside of the driving arm 102.

[0063] Further, two support arms 101 are arranged. A support plate is arranged between the two support arms 101. The support plate is connected to the main body frame 13, and an energy device 15 is arranged on the support plate.

[0064] In this embodiment, arranging two support arms 101 can better support the tool holder 100. In addition, the two support arms 101 make the force more uniform. The two driving arms 102 are fixed by a support rod 104, making the wheel 12 more stable.

[0065] It should be noted that the support rod 104 can be a part of the main frame 13 or a separate structure for stabilizing the wheel 12.

[0066] In other embodiments, a steering device is further provided on the driving arm 102. The wheel 12 is connected to the driving arm 102 through the steering device, and the steering device is used to control the rotation of the wheel 12.

[0067] The energy device 15 includes, but is not limited to, a fuel cell. Cooperating with the power device 14, it can achieve the hybrid drive of the cutting device 1 and improve the overall endurance time of the cutting device 1.

[0068] Furthermore, in one of the embodiments, an abutting member 103 is provided on the driving arm 102. The abutting member 103 is movably arranged on the driving arm 102, and the abutting member 103 is connected to the support arm 101.

The abutting member 103 can be a movable step provided on the side of the driving arm 102, or the abutting member 103 is arranged inside the driving arm 102 and forms a telescopic structure with the driving arm 102 so that the abutting member 103 can extend out from the inside of the driving arm 102.

[0070] Specifically, a driving member is arranged inside the driving arm 102, and one end of the driving member is connected to the abutting member 103.

[0071] It can be understood that the driving member can be a traditional hydraulic cylinder or a telescopic rod for driving the abutting member 103 to move. The driving member remains in a fixed state, which is beneficial to the stability of the wheel 12 and the entire main frame 13. In addition, when the driving member acts, the wheel 12 is mainly stressed and does not affect the use of other structures.

[0072] In some other embodiments, the driving member can be a meshing gear structure.
