[0027] The cutting mechanism 1 is composed of a guard plate 101, a guard plate mounting seat 102, a blade 103, a cutter disc drive shaft 104, a cutter disc 105, a cutting component mounting sleeve 106, a cutting hydraulic motor 107, a cutting component bracket 108, and a blade mounting pin 109. The power is transmitted from the cutting hydraulic motor 107 to the cutter disc 105 through the cutter disc drive shaft 104. The blade 103 rotates together with the cutter disc 105 through the blade mounting pin 109. The guard plate 101 is mounted on the guard plate mounting seat 102. The guard plate mounting seat 102 is connected to the cutter disc drive shaft 104 through a bearing and a retaining spring. The cutting component The mounting sleeve 106 is located below the cutting hydraulic motor 107. The upper plane of the cutting component mounting sleeve 106 is connected to the hydraulic motor 107. The mounting hole of the side plane of the cutting component mounting sleeve 106 is connected to the mounting hole of the cutting component bracket 108. The cutting component bracket 108 is designed as a parallel four-bar linkage. The cutting mechanism 1 is installed on the front and rear crossbeams of the side truss 10 and the middle truss 12 in a manner that the positions of two adjacent cutting mechanisms 1 are staggered from front to back. A bracket for installing the oil tank 3 is welded in the middle of the crossbeam of the middle truss 12. The oil tank 3 A hydraulic pump 2 is installed below; the middle truss 12 has pin holes at both ends, which are connected to the side truss 10 through the pin 13. The middle truss connection protection body 121 is provided in front of the pin holes at both ends of the middle truss 12. The middle truss connection protection body 121 protects the pin 13 and reduces wear. The side truss pulling hydraulic cylinder 11 lugs are welded on the middle truss 12 crossbeam and the side truss 10 crossbeam. By controlling the side truss pulling hydraulic cylinder 11 to move, the side truss 10 is respectively in a horizontal working state and a vertical transfer state; the front support frame 4 is connected to the middle truss 12 in an articulated manner, and the diagonal tie rod (5 ) is hinged to the front support frame (4), and the other end of the inclined tie rod (5) is hinged to the middle truss (12). The relative angle between the front support frame 4 and the middle truss 12 is changed by adjusting the inclined tie rod (5); the other end of the front support frame 4 is hinged to the power body 7, and one end of the front lifting hydraulic cylinder 6 is hinged to the front support frame 4, and the other end is hinged to the power body 7. By controlling the action of the front lifting hydraulic cylinder 6, the lifting of the front support frame 4 is adjusted, thereby controlling the height of the middle truss 12; the front support frame 4 is hung in front of the power body 7, and the grass raking mechanism 8 is installed at the back of the power body 7. The movement of the power body 7 is driven by hydraulic pressure;

[0028] The grass raking component includes a grass raking mechanism 8, which is composed of a finger wheel mounting arm holder 801, a pressure reducer 802, a finger wheel mounting arm 803, a finger wheel 804, a side pull rod 805, a suspension arm 806, a side flip arm 807, a side pull rod mounting sleeve 808, a side flip arm pulling hydraulic cylinder 809, a grass raking component mounting frame 810, and a side mounting arm pin 811. The grass raking component mounting frame 810 is installed behind the power body 7, and mounting holes are provided at both ends of the grass raking component mounting frame 810. The mounting holes of the grass raking component mounting frame 810 are hinged to the side flip arm 807 through the side mounting arm pin 811. Support ears are welded on the grass raking component mounting frame 810 and the side flip arm 807. The side flip arm pulling hydraulic cylinder 809 is hinged to the support ears on the grass raking component mounting frame 810 and the side flip arm 807. The side flip arm 807 is controlled by controlling the action of the side flip arm pulling hydraulic cylinder 809. The vertical and horizontal states of the side flip arm 807 are hinged to the center of gravity of the suspension arm 806 at the other end; small shafts are welded on the sides of the two ends of the grass raking component mounting frame 810, and the side pull rod mounting sleeve 808 is installed on the small shaft and can rotate around the axis of the small shaft. One end of the side pull rod 805 is installed on the side pull rod mounting sleeve 808, and the other end is hinged to the suspension arm 806. By adjusting the length of the side pull rod 805, the relative angle between the side flip arm 807 and the suspension arm 806 can be changed; the finger wheel 804 is installed at one end of the finger wheel mounting arm 803, and can rotate freely perpendicular to the axis of one end of the finger wheel mounting arm 803, and the other end of the finger wheel mounting arm 803 is installed on the suspension arm 806 through the finger wheel mounting arm holder 801, and the finger wheel mounting arm 803 can rotate relatively around the finger wheel mounting arm holder 801, and one end of the pressure reducer 802 is connected to the finger wheel mounting arm 803, and the other end of the pressure reducer 802 is connected to the suspension arm 806.

[0029] Specifically, a self-propelled fully hydraulic cutting and rake device has two operating modes.

[0030] One is the transfer mode. For the convenience of walking and the needs of roads, the side truss 10 is pulled by the side truss pulling hydraulic cylinder 11 so that the side truss 10 is in a vertical state and is perpendicular to the middle truss 12. At the same time, the front support frame 4 rises under the push of the front lifting hydraulic cylinder 6, so that the front support frame 4 drives the middle truss 12 and the side truss 10 to rise together; the side flip arm pulling hydraulic cylinder 809 contracts to pull the side flip arm 807 to rise, and finally the side flip arm 807 reaches a vertical state, thereby driving the suspension arm 806 and the finger wheel mounting arm holder 801, pressure reducer 802, finger wheel mounting arm 803, finger wheel 804, side pull rod 805 installed on the suspension arm 806 to flip together, so that the finger wheel 804 is off the ground. During the transfer process, the width of a self-propelled fully hydraulic cutting and rake integrated device is reduced.

[0031] One is the operation mode, adjusting the cutting mechanism 1 to the operation state, the side truss pulls the hydraulic cylinder 11 to extend, so that the side truss 10 and the middle truss 12 are both in a horizontal state, and the front lifting hydraulic cylinder 6 is controlled to lower the front support frame 4. When the guard plate 101 reaches the ideal operation height from the ground, the action of the front lifting hydraulic cylinder 6 is stopped and this height is maintained; adjusting the grass raking mechanism 8 to the operation state, the side flip arm pulls the hydraulic cylinder 809 to extend, so that the side flip arm 807 is horizontal, thereby driving the suspension arm 806 and the finger wheel mounting arm holder 801, the pressure reducer 802, the finger wheel mounting arm 803, the finger wheel 804, and the side pull rod 805 installed on the suspension arm 806 to flip together, so that the finger wheel 804 contacts the ground.

[0032] During the operation, the high-speed rotating cutter disc 105 drives the blade 103 to rotate at high speed to cut grass or straw through the blade mounting pin 109. When encountering a hard object, the blade 103 rebounds into the cavity of the cutter disc 105 with the blade mounting pin 109 as the center, thereby protecting the blade 103 from damage; when encountering a sudden rise of the ground or protruding debris, the parallel four-bar linkage of the protective disc 101 and the cutting component bracket 108 works together to lift the cutting mechanism 1, thereby playing a role in avoiding obstacles and protecting the various components in the cutting mechanism 1 from damage; the two side flip arms in the grass raking mechanism 8 can pull the hydraulic cylinder 809 and can be controlled separately, that is, the side flip arm 807 on one side can be in a horizontal position, so that the finger wheel 804 is in an operating state, and the side flip arm 807 on the other side is in a vertical position, so that the finger wheel 804 is idle, or the side flip arms 807 on both sides can be in a horizontal position at the same time, and the finger wheel 804 is in an operating state.
