Specific embodiment
Below with reference to embodiment, the utility model will be further described, but does not constitute to any of the utility model
Limitation, the modification of anyone limited times made in the utility model claims range are still wanted in the right of the utility model
It asks in range.
Specific embodiment of the utility model is such that referring to Fig.1 shown in -6, a kind of chaffcutter device, including hollow machine
Frame 3, rack 3 is interior to be equipped with hobboing cutter shaft 1, the removable moving knife 5 for being equipped with multiple groups and being spirally evenly arranged in hobboing cutter shaft 1, rack 3
The interior stationary knife seat assembly 2 for being equipped with the arranged beneath positioned at hobboing cutter shaft 1 is removable on stationary knife seat assembly 2 to be equipped with multiple uniform rows
The stationary knife 8 of column, the stationary knife 8 on stationary knife seat assembly 2 are staggeredly arranged with the moving knife 5 in hobboing cutter shaft 1, and when cutting, it is fixed to can use
Knife 8 and moving knife 5, which staggeredly be engageds, carries out crushing type cutting to forage, be equipped between stationary knife seat assembly 2 and rack 3 adjust stationary knife 8 and
The regulating mechanism 9 of the distance of moving knife 5, can control the degree of this crushing of forage by regulating mechanism 9;This chaffcutter device improves existing
The arrangement mode of some moving knife 5, it is each that moving knife 5 is only cut within each gyration period of hobboing cutter shaft 1 by Heterogeneous Permutation
It cuts primary.Each is all to intersect to be shredded in the same time interval with stationary knife 8 in turn moving knife 5, and moving knife 5 and stationary knife 8
Upper load is uniform, and broken grass effect is good, also greatly reduces power consumption;Meanwhile structure is simple, and it is easy for installation, convenient for independent
The blade of damage is replaced, it can be achieved that all stationary knife synchronous adjustments position when adjusting stationary knife angle.It is adjusted by regulating mechanism more than 9
The different angle of shelves adjusts stationary knife 8 at a distance from moving knife 5, it can be achieved that different choppings requires.
In the present embodiment, every group of moving knife 5 is uniformly distributed along the excircle of hobboing cutter shaft 1, axis of the moving knife 5 in hobboing cutter shaft 1
Spacing is identical on direction.
In the present embodiment, on the outer circumference surface of hobboing cutter shaft 1 helically formula be evenly arranged be equipped with multiple groups and moving knife 5 it is right
The moving knife tool apron 4 that should be arranged, parallel to each other and spacing is equal after the helix expansion that each group moving knife tool apron 4 is formed;Moving knife and dynamic
Knife tool apron 4 can be installed one by one, be dismantled, and position also can adjust in a certain range, the spacing needed for meeting when being easily installed
It is required that.
In the present embodiment, moving knife tool apron 4 is the inserting slot construction compatible with moving knife 5 being arranged in hobboing cutter shaft 1, is inserted
Slot structure is equipped with the positioning pin 10 of positioning moving knife 5, and moving knife tool apron 4 and institute's rotating shaft assembly 1 are to be welded to connect.
In the present embodiment, as shown in Fig. 2, on the direction perpendicular to 1 axis of hobboing cutter shaft, two neighboring moving knife tool apron
Radial angle between 4 is 10~30 °, in certain revolving speed, it is ensured that hobboing cutter shaft 1 to the cutting times of forage without
It causes load excessive, maximally utilizes the power of grass trimmer, small power consumption, use cost is low.
In the present embodiment, moving knife 5 is double-edged blade, can be 180 ° at same moving knife tool apron 4 after the edge wear of side
Installation is exchanged, other side blade is continued to use.
In the present embodiment, stationary knife 8 is equipped with connecting plate 6, by bolt arrangement 11 by connecting plate 6 and stationary knife seat assembly 2
Locking, locking effect is good, easy to operate.
In the present embodiment, stationary knife 8 is to be arranged in pairs on connecting plate 6, and the stationary knife 8 on stationary knife seat assembly 2 is uniformly arranged,
