[0029] In addition, the bolt 111 is connected with the single-hole blade mounting seat 103 and penetrates the single-hole blade mounting seat 103 and the first rotary tillage blade 104; the nut 112 is threadedly connected with the bolt 111 and is sleeved on the bolt 111; the first rotary tillage blade 104 and the single-hole blade mounting seat 103 are both provided with through holes matched with the bolt 111, the single-hole blade mounting seat 103 is provided with a slot matched with the first rotary tillage blade 104, when the first rotary tillage blade 104 is installed, the first rotary tillage blade 104 is inserted into the slot on the single-hole blade mounting seat 103, at this time, the through holes on the first rotary tillage blade 104 are aligned with the through holes on the single-hole blade mounting seat 103, at this time, the bolt 111 penetrates the through holes on the single-hole blade mounting seat 103 and the first rotary tillage blade 104, finally, the nut 112 is screwed on the bolt 111, so that the installation of the first rotary tillage blade 104 is completed.
[0030] Meanwhile, the seat body 113 is connected with the cutter barrel 101 and is arranged on the cutter barrel 101; the adjusting bolt 114 penetrates the seat body 113 and is threadedly connected with the cutter barrel 101,
[0031] Then, the cutter barrel 101 is provided with a threaded hole 115, the threaded hole 115 is arranged on the side of the cutter barrel 101 close to the adjusting bolt 114 and penetrates the cutter barrel 101.
[0032] The threaded hole 115 is arranged in plurality and is arranged along the length direction of the cutter barrel 101, the plurality of threaded holes 115 are uniformly arranged on the cutter barrel 101, the bottom of the seat body 113 is provided with a through hole matched with the adjusting bolt 114, when the seat body 113 is installed, the through hole in the bottom of the seat body 113 is aligned with one of the threaded holes 115, then the adjusting bolt 114 penetrates the through hole on the seat body 113 and is connected with the threaded hole 115, so that the seat body 113 is installed on the cutter barrel 101, through the plurality of threaded holes 115, the seat body 113 can be installed at different positions of the cutter barrel 101, so that the positions of the seat body 113 and the first rotary tillage blade 104 are adjusted.
[0033] Then, the limiting slot 116 is arranged on one side of the seat body 113 and is matched with the bolt 111; when the nut 112 is screwed tightly, the head of the bolt 111 is clamped into the limiting slot 116, so that the bolt 111 is limited by the limiting slot 116, through the circumferential limiting action of the limiting slot 116, the self-rotation tendency of the bolt 111 due to high-speed rotation vibration of the equipment is eliminated; the bolt 111 is prevented from loosening.
[0034] Finally, the clamping groove 117 is arranged on one side of the seat body 113 close to the cutter barrel 101, and the clamping groove 117 is matched with the cutter barrel 101; when the seat body 113 is installed in place, the clamping groove 117 is clamped with the cutter barrel 101, so as to limit the circumferential rotation of the seat body 113 relative to the cutter barrel 101, prevent the loosening or deflection of the mounting seat caused by vibration or resistance, and enhance the reliability and safety of work.
[0035] When the convenient interval adjustment composite cutter of the embodiment is used, the cutter barrel 101 is driven to rotate by the agricultural machine, and then the single-hole blade mounting seat 103, the first rotary tillage blade 104, the three-hole blade mounting seat 105, the second rotary tillage blade 106 and the crawling plate 107 are driven to rotate, so that the first rotary tillage blade 104 and the second rotary tillage blade 106 efficiently cut and crush the soil and rhizomes, and at the same time, the tooth-shaped protrusions 109 and the straw crushing protrusions 110 on the crawling plate 107 cooperate to further crush the straw and provide auxiliary traction; when it is necessary to adjust the operation mode according to different agricultural requirements, the bolt 111 is loosened, the first rotary tillage blade 104 is disassembled from the single-hole blade mounting seat 103, then the adjusting bolt 114 is loosened, the single-hole blade mounting seat 103 is moved to the target position along the axial direction of the cutter barrel 101, and then it is fastened again after the through hole at the bottom of the single-hole blade mounting seat 103 is aligned with another threaded hole 115; in this way, the axial distance of adjacent cutter groups can be changed, so as to adjust the crushing density, and the number of the single-hole blade mounting seats 103 can also be increased or reduced as needed to match different operation width and intensity requirements; since the cross section of the cutter barrel 101 is a regular hexagon, the single-hole blade mounting seat 103 can be reinstalled on six different sides of the cutter barrel 101; when an individual rotary tillage blade is worn or damaged, the bolt 111 and the nut 112 fixing the blade only need to be loosened, and then the blade can be taken out from the insertion slot of the single-hole blade mounting seat 103 for replacement, so that the maintenance process is simple and fast, the entire cutter roller does not need to be disassembled, and welding equipment is not needed, which significantly reduces downtime and maintenance cost; one device can meet the needs of various differentiated operation scenes, which greatly improves the efficiency, economy and flexibility of agricultural operation.
