Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is a portable device that can be used for tasks such as trimming garden trees, mowing grass on banks, etc. This relates to a mowing machine.

0002

[Conventional technology]

Traditionally, this type of mower has a portable engine with a horizontally protruding support rod. It is supported by this support rod and moves back and forth along the support rod by the engine drive. A first clipper blade provided on a freely movable first sliding rod, and a first clipper blade supported by a support rod, It is installed on the second sliding rod that slides relative to the clipper blade, and performs cutting work between it and the first clipper blade A second clipper blade was also provided for the purpose.

0003

[Problem that the idea aims to solve]

Conventionally, with this type of mower, when mowing the top surface of the shrubbery, The cut pieces of dead leaves are scattered after cutting, making it difficult to see the pruning marks clearly, making it difficult to mow neatly. It was difficult to align. For this reason, a leaf receiving plate 53 as shown in FIG. 7 is supported. It was stuck to the top surface of rod 19. The leaf receiving plate 53 has the edge opposite to the clipper blade facing upward. It is formed in a diagonally bent shape at an obtuse angle. Top surface of implant with clipper blade After trimming a little, I return it to the rear and inspect the mowing marks, but the cut pieces are Since it is received on the leaf receiving plate 53, it moves backward while riding on the leaf receiving plate 53. Inspect the mowing marks and trim them neatly to ensure that no cut pieces fall into the mowing marks. can become. Repeat this process to proceed with the cutting, and the cut pieces will be placed on the leaf receiving plate 5. 3. If the leaves accumulate on the top, they will be pushed up onto the diagonally bent slope, and the leaves will be pushed up from the leaf receiving board to the top of the shrubbery. It will fall on the surface, but the area where it fell will be the area after the mowing has been inspected, so check it. There is no problem. This conventional leaf catcher plate 53 is used for mowing grass on the banks. After that, you have to drop the grass and it becomes a hassle to collect and clean the grass pieces. was.

0004

[Means to solve the problem]

The present invention has an edge on the upper surface of the support rod opposite to the first clipper blade and the second clipper blade. At the top, there is a grass board bent at an almost right or acute angle. .

[0005]

[Effect]

When mowing the grass on the banks, the cut grass pieces are caught on the grass board and stagnant. However, since the upwardly bent part is vertical or at an acute angle, the grass pieces are pushed backwards. While mowing the grass, it is not removed and the grass accumulates on the grass board. It is something that gathers people together.

【Example】

Hereinafter, one embodiment of the present invention will be described with reference to the drawings. The mower 1 is as follows. It is configured as follows. That is, the rear handle 3 is a main body case that is fixed to the engine 5. is stuck to the base (not shown).

[0007] The engine 5 includes a muffler cover 7, an air cleaner 9, a fuel tank 11, and a rear cylinder. a coil starter 13; a cylinder cover 15 that covers a cylinder (not shown); A fan cover 17 is provided. A support rod 19 projects horizontally on the main body case. The front handle 21 is fixed to the upper surface. The front handle 21 has a grip A protector 23 is attached to protect the hand.

[0008] The support rod 19 includes a first sliding rod 25 and a second sliding rod that are superimposed and slidably supported. The rod 27 is supported by a bolt 33 passing through long holes 29 and 31 provided in each. It is. The bolt 33 is screwed into the support rod 19 and fixed with a nut 35. Ru. The first sliding rod 25 and the second sliding rod 27 have first clipper blades 37 that are slidable on each other. , and the second clipper blade 39 are fixed to each other. First sliding rod 25, second sliding rod 2 7 are provided so as to reciprocate in opposite directions when driven by the engine 5. .

[0009] A longitudinal oil groove 41 is provided on the sliding surface between the first sliding rod 25 and the second sliding rod 27. connected to a lubricating oil tank 43 provided in the main body case via a cock (not shown). The sliding surface is lubricated by gravity. In addition, the first sliding rod 25 and the support rod 19 An oil groove may also be provided on the sliding surface. The lubricating oil is stored in the lubricating oil tank under crankcase pressure. It may be provided so that it is pressurized by force and sent to the oil groove 41.

0010 At the base of the support rod 19, there is a It protrudes in front of the cutting (to the side of the clipper blade side of the support rod 19) and is shaped like a comb at appropriate intervals. A protective plate 47 provided with protective pieces 45, 45, etc., each having a downwardly bent tip. are fixed with bolts 35. These protective pieces 45, 45... can be supported as necessary. It may be provided over the entire length of the retainer 19.

[0011] A weed plate 49 with an L-shaped cross section extends from the center to the tip of the upper surface of the support rod 19. are fixed with bolts 35. The grass board 49 has the rear edge of the horizontal section facing upwards. It is formed into a shape bent at a nearly right angle or an acute angle. In addition, the main case has If necessary, a separate long handle frame 51 is detachably attached.

0012 To perform mowing work, the operator must remove the handle frame 51 and move the front Hold the steering wheel 21 and rear handle 3 with both hands, and move them back and forth relative to each other using the engine 5. Trimming of tree branches, etc. between the moving first clipper blade 37 and second clipper blade 39 It is used to carry out assembly work. You can also attach the handle frame 51 to mowing the grass on the banks. It is something that performs work.

[0013] The amount of lubricating oil in the lubricating oil tank 43 is adjusted by a cock (not shown). The oil passes through the oil groove 41 and lubricates the sliding surface between the first sliding rod 25 and the second sliding rod 27.

[0014] In addition, cut grass pieces, etc. are received on the weeding board 49 and bent upward. It is pushed forward and collected by the vertical part of the shape. Sara In the part where the protective piece 45 is provided, from between the comb-shaped protective pieces 45, 45, Tree branches, grass, etc. have invaded and the cutting work can be carried out as usual without any problems, but this part If you try to touch the worker's waist, legs, etc., the tip of the protective piece 45 will come into contact first and the bar will be damaged. It can prevent the recan blade from coming into contact with each other.

[0015]

[Effect of the idea]

According to the present invention, the grass pieces cut by the clipper blade are received by the weeding board, By gathering the grass in front of you while cutting, you can avoid leaving any debris in the mowing area. This eliminates the hassle of collecting grass after cutting.
