Detailed Description

The invention will be further described with reference to the accompanying drawings.

As shown in fig. 1-7, a grass combing knife for a grass raker comprises a main shaft 6, wherein the main shaft 6 is sleeved with a plurality of blade spacers 3, a grass combing knife fixing frame 4 is arranged between every two adjacent blade spacers 3, the grass combing knife fixing frame 4 comprises a bending base 41 and spring knife sleeves 42 symmetrically arranged at the tail ends of the base, each spring knife sleeve 42 is provided with a grass combing spring knife 2, one end of each grass combing spring knife 2 abuts against the main shaft 6, and the other end of each grass combing spring knife 2 is a free end.

The front end of the main shaft 6 is provided with a positioning pin 1, the rear end is provided with a locking nut 5, and a gasket 7 is arranged between the positioning pin 1, the locking nut 5 and the blade spacer 3 at the corresponding position.

The main parts through with comb grass sword all install the main shaft through the mode of suit on, both ends are fixed through locating pin and lock nut, even the part of intermediate position appears damaging the condition in the use, also change that can be convenient. And through adopting the mode of combing the grass spring sword, with its one end support on the main shaft, the other end is the free end, at the in-process of combing the grass, utilizes the reverse elasticity effect of combing the grass spring sword, can effectively improve and collect grass efficiency, moreover under the effect of spring force, also can play certain buffering guard action to blade itself.

The center of the blade spacer 3 is provided with an opening 31 which is identical with the cross section shape of the main shaft 6 and can be sleeved on the main shaft 6, the side surfaces of two sides of the blade spacer 3 are respectively provided with a first clamping groove 32 which is identical with the side surface shape of the bent base 41 and a second clamping groove 34 which is identical with the side surface shape of the spring knife pouch 42, and the center of the second clamping groove 34 is provided with a positioning column 33 which can be inserted into the spring knife pouch 42.

The first blade spacer 3 is sleeved on the main shaft 6 and then positioned by the positioning pin 1, one side of the grass combing blade fixing frame 4 provided with the two grass combing spring blades 2 is connected with the first clamping groove 32, the second clamping groove 34 and the positioning column 33 on the first blade spacer 3, the second blade spacer 3 is sleeved on the main shaft 6, the first clamping groove 32, the second clamping groove 34 and the positioning column 33 are connected with the other side of the grass combing blade fixing frame 4, then the other side of the second blade spacer 3 is connected with the next grass combing blade fixing frame 4, and the installation is carried out once until the whole is completed, the last blade spacer 3 is fixed by the locking nut 5, and the assembly of the whole cutter is completed.

The main shaft 6 is a hexagonal shaft, the opening 31 is a hexagonal hole corresponding to the shape and size of the opening, and the first clamping groove and the second clamping groove on the same side surface of the blade spacer 3 are staggered by 120 degrees by taking the circle center of the opening 31 as the center relative to the first clamping groove and the second clamping groove on the other side surface. Through adopting the hexagonal axle structure with the cross-section of main shaft 6, blade spacer 3 is installed and is gone just can not rotate after going, because first draw-in groove and the second draw-in groove on the relative another side of first draw-in groove and second draw-in groove on the blade spacer 3 same side use the centre of a circle of trompil 31 to misplace 120, consequently in order to satisfy the installation demand, two adjacent blade spacers 3 are installed on main shaft 6 after the in-process clockwise rotation 120 of suit, the contained angle between two adjacent grass combing flickers 2 of bending on the form base 41 of bending on main shaft 6 has also been realized simultaneously is 120, make every grass combing flicker 2 of group on the whole main shaft 6 fixed with the mode of dislocation, be favorable to improving grass collecting efficiency.

In conclusion, the grass combing knife for the grass raker provided by the invention is convenient to disassemble and assemble in the whole structure, and the grass combing knife can effectively protect the blades and remarkably improve the grass collecting efficiency by utilizing the rebound force of the grass combing spring knife in the using process.
