Technical Field

[0001] The utility model specifically relates to a cutting device of a harvester. Background Art

[0002] Sugarcane is one of the important cash crops in southern my country. The sugar content of sugarcane stalks is as high as 55%-70%. The sucrose produced by processing it occupies an important position in our production and life. In addition, the processed bagasse is also a good raw material for brewing and papermaking. In 2011, the planting area of ​​sugarcane in Guangxi, Hainan, Fujian, Yunnan and other places in my country reached 25.5697 million mu. According to the per mu yield of sugarcane of 4 tons / mu, the annual output of raw material sugarcane exceeds 100 million tons, and the total output of sucrose reaches 14 million tons / year.

DETAILED DESCRIPTION

[0016] In order to make the above features and advantages of the present invention more obvious and understandable, embodiments are given below with reference to the accompanying drawings for detailed description as follows.

[0017] like Figures 1 to 4 As shown, a cutting device of a harvester includes a supporting arm 61, a rotating middle arm 62 and a cutting seat 63, wherein one end of the supporting arm 61 is mounted on the harvester 1, one end of the rotating middle arm 62 is mounted on the other end of the supporting arm 61, the cutting seat 63 is mounted on the other end of the rotating middle arm 62, a cutting motor is mounted on the cutting seat 63, a cutting blade 64 is mounted on the bottom of the cutting motor, and a clamp auxiliary device is rotatably provided on the cutting seat 63.

[0018] The clamp auxiliary device includes a mounting seat 71, a first clamping jaw 72, a second clamping jaw 73 and a clamping hydraulic cylinder 74. The mounting seat 71 is mounted on the top of the cutting seat 63. The front end surface of the mounting seat 71 is provided with a rotating frame 76. The rear end of the mounting seat is provided with a rotating motor 77 for driving the rotating frame to rotate. The inner ends of the first clamping jaw 72 and the second clamping jaw 73 are both rotatably mounted on the rotating frame 77. The clamping hydraulic cylinder 74 is mounted on the rotating frame 76 to drive the first clamping jaw 72 and the second clamping jaw 73 to open and close. When in use, the clamping hydraulic cylinder 74 controls the first clamping jaw 72 and the second clamping jaw 73 to open, and the cutting machine 1 moves to a position so that the harvested object is located between the first clamping jaw 72 and the second clamping jaw 73, and then closes the two clamping jaws while cutting. When the harvested object is cut, the rotating frame 76 is controlled to rotate by the rotating motor 77, and the long strip of harvested object can be placed horizontally to prevent the harvested object from tipping over.

[0019] In this embodiment, the mounting seat 71 is swingably mounted on the rotating middle arm 62 of the cutting machine 1 , and a swing hydraulic cylinder 65 for driving the mounting seat 71 to swing is disposed on the rotating middle arm 62 .

[0020] By driving the mounting seat to swing through the swing hydraulic cylinder 65, the double clamps can be conveniently guided to feed the cut sugar cane into the harvester, and the harvester can process the fed sugar cane.

[0021] In this embodiment, the cylinder body 65 of the swing hydraulic cylinder is rotatably mounted on the rotating middle arm 62 , and the piston end of the swing hydraulic cylinder 65 is hinged to the mounting seat 71 .
