い。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described in detail with reference to the drawings. Reference numeral 1 denotes a transmission case, which is attached to a power take-out position of an engine or a transmission motor, is formed to be thin in the up-down direction, has a hollow interior, and has a front-rear sliding work in front and rear of an intermediate portion between left and right. Fitting part 1 for receiving moving member
a and 1b are formed. Reference numeral 2 denotes a main shaft, which is linked to a drive shaft of an engine or a transmission motor and is driven to rotate. A is a transmission means of the reciprocating cutting blade device. In the illustrated example, the drive eccentric cams 3a, 3b formed integrally with the main shaft 2 in a disk shape partially overlap on the upper side and the lower side and project in the front-rear direction. Are provided in a state shifted by 180 degrees, and cam walls a, b, c, which fit the drive eccentric cams 3a, 3b on the front and rear sides, are provided.
d, and an elongated hole 4a through which the spindle 2 is inserted.
In the illustrated example, operating members 6 and 7 are integrally provided on the front side of the driven cam bodies 5a and 5b of the transmission means A.
The front and rear intermediate portions of the operating members 6 and 7 are slidably received by the fitting portion 1a of the transmission case 1 via the support metal 8, and the distal end portion protrudes from the transmission case 1 and is moved back and forth. ing. (A) and (b) are rear projections projecting from the rear of the driven cam bodies 5a and 5b, and are slidably supported by a support metal 9 provided on the rear side of the transmission case 1. Reference numerals 10 and 11 denote cutting blades, which are made of a steel plate elongated in the front-rear direction, and have blade portions 10t and 11 on the left and right sides in plan view.
t is formed. The cutting blades 10, 11 are linked to the upper and lower operating members 6, 7 by the following means. That is, engaging pin portions 6a, 7a having a circular shape in a plan view are formed at the tip portions of the operating members 6, 7, and the cutting blade bodies 10, 1 are formed.
1 are formed on the base side thereof with engaging holes 10a and 11a for fitting the engaging pins 6a and 7a, and the pin 6a and the hole 10a, and the pin 7a and the hole 11a are connected to each other. It is a connection means that can be freely engaged and disengaged. In addition, as shown in FIG. 3, this connecting means does not form the engaging pin portions 6a, 7a having a circular shape in plan view at the distal end portions of the operating members 6, 7, as shown in FIG.
b, 7b, the operating members 6, 7 and the cutting blades 10, 11
And a bolt 13 and a nut 14
A means for linking with may be taken. Numeral 12 denotes a cutting blade holding frame, which holds the cutting blade bodies 10 and 11 from below, and cuts the upper and lower two cutting blade bodies at the front and rear intermediate portions so that the cutting blade bodies 10 and 11 can freely move back and forth. A stepped bolt 16 inserted into the elongated holes 15a and 15b is screwed and connected by a nut 17.
The operation of the above example will be described. When the power is transmitted from the drive eccentric cams 3a, 3b to the driven cam bodies 5a, 5b by the rotation of the main shaft 2, and the driven cam bodies reciprocate in the front-rear direction, the driven cam bodies 5a , 5b integral operating members 6, 7
Slides back and forth while being received by the fitting portion 1a of the transmission case 1. Then, the cutting blades 10, 11 attached to these operating members 6, 7 by means of freely releasable connecting means reciprocate back and forth, and reciprocate with the clippers. When the clippers reciprocate, that is, when the upper and lower cutting blades 10 and 11 repeatedly move at high speed to cut weeds and plants, the blade portions 10t and 11t of the cutting blades 10 and 11 are spilled during use. When the cutting blades 10 and 11 are replaced or polished in a case where the cutting performance is poor or the cutting performance is poor, the bolts 16 and the nuts 17 can be removed without disassembling the case 1. It is only necessary to remove it from the device 12, and disassembly and assembly can be made extremely easy. Also, the upper and lower blades 10,
11 is pin-fitted to the upper and lower operating members 6 and 7 and is operated back and forth, and furthermore, is held firmly by the cutting blade holding frame 12, so that no play occurs when the cutting blade bodies 10 and 11 are operated. .
【発明の効果】この発明によると、作動部材に刈刃体を
取り付けるにあたり、嵌合係脱型に連結ならしめたか
ら、作動部材から刈刃体を脱着する作業が簡単で、刈刃
体の研磨作業や交換が容易であり、且つ、刈刃体の作動
