Description

本発明は、刈り刃ハウジングの内部に、刈り刃ハウジング上下向き軸芯まわりで駆動回転自在な一対の回転刈り刃が刈り刃ハウジング横方向に並んで位置するとともに、刈り刃ハウジング前後方向視で前記一対の回転刈り刃の回転域が重なり合う重合部が形成され、前記一対の回転刈り刃からの風に案内作用するよう前記一対の回転刈り刃の前方に位置した前バッフルを備えたモーアに関する。   In the present invention, a pair of rotary cutting blades that can be driven and rotated around the vertical axis of the cutting blade housing are arranged side by side in the horizontal direction of the cutting blade housing, and the cutting blade housing is viewed in the front-rear direction. The present invention relates to a mower provided with a front baffle formed in front of the pair of rotary mowing blades so as to form an overlapping portion where the rotation areas of the pair of rotary mowing blades overlap and to guide and act on the wind from the pair of rotary mowing blades.

上記したモーアとして、従来、たとえば特許文献1に示されるものがあった。特許文献1に示されるものは、デッキ(刈り刃ハウジングに相当)の横方向に並ぶ3枚のブレード(回転刈り刃に相当)、ブレードの回転軌跡(回転域に相当)が合流するオーバラップ部(重合部に相当)、ガイド板(前バッフルに相当)を備えている。   Conventionally, for example, Patent Document 1 discloses a mower described above. Patent Document 1 discloses an overlap portion in which three blades (corresponding to a rotary cutting blade) arranged in the lateral direction of a deck (corresponding to a cutting blade housing) and a rotation locus (corresponding to a rotation region) of the blades merge. (Corresponding to the overlapping portion) and a guide plate (corresponding to the front baffle).

この種のモーアにおいて、刈り処理しょうとする草が前記重合部に入り込むと、刈り残しなど、刈り処理不良が発生しやすくなる。このため、特許文献1に示されたモーアは、分草板を備え、前記刈り処理不良の抑制を図っている。すなわち、オーバラップ部に前側から入ろうとする芝草を分草板の分離作用によって左右両側に振り分けて分草して後方に送る。   In this type of mower, when the grass to be mowed enters the superposed portion, a marrowing defect such as uncut mushrooms is likely to occur. For this reason, the mower shown by patent document 1 is provided with the weed board, and is aiming at suppression of the said mowing process defect. That is, turf grass entering the overlap portion from the front side is distributed to the left and right sides by the separating action of the weed board and divided and sent to the rear.

特開2002−153112号公報(段落〔0005〕−〔0008〕、〔0015〕−〔0021〕、図1−3)JP 2002-153112 A (paragraphs [0005]-[0008], [0015]-[0021], FIG. 1-3)

上記した従来の技術を採用すると、分草板を特別に備える必要があった。このため、分草板と前バッフルとによって前向き開口の凹入空間が前バッフルの前側に形成されるとともに、この凹入空間の横幅が後方側に至るほど狭くなり、分草板によって分草された草が分草板と前バッフルの間に詰まる事態が発生しやすくなっていた。また、必要な部材数が多くなっていた。   When the above-described conventional technique is employed, it is necessary to specially provide a weed board. For this reason, a recessed space with a forward opening is formed on the front side of the front baffle by the weed board and the front baffle, and the lateral width of the recessed space becomes narrower toward the rear side, and the weeds are divided by the weed board. It was easy for the grass to get stuck between the weed board and the front baffle. In addition, the number of necessary members has increased.

本発明の目的は、前記重合部への草の入り込みを上記した問題発生を回避しながら抑制することができるモーアを提供することにある。   An object of the present invention is to provide a mower that can suppress the entry of grass into the superposition part while avoiding the above-described problems.

本第1発明は、刈り刃ハウジングの内部に、刈り刃ハウジング上下向き軸芯まわりで駆動回転自在な一対の回転刈り刃が刈り刃ハウジング横方向に並んで位置するとともに、刈り刃ハウジング前後方向視で前記一対の回転刈り刃の回転域が重なり合う重合部が形成され、前記一対の回転刈り刃からの風に案内作用するよう前記一対の回転刈り刃の前方に位置した前バッフルを備えたモーアにおいて、
前記前バッフルを、この前バッフルの前記一対の回転刈り刃の一方の回転刈り刃の回転域に対向した横一端側部と、他方の回転刈り刃の回転域に対向した横他端側部との境界が前記重合部から刈り刃ハウジング横端側に外れて位置するよう構成し、前記前バッフルの前記横一端側部が草を前記重合部から刈り刃ハウジング横端側に外れた箇所に向けて押圧操作するよう構成してある。
In the first invention, a pair of rotary cutting blades that can be driven and rotated around the vertical axis of the cutting blade housing are arranged side by side in the horizontal direction of the cutting blade housing, and the cutting blade housing is viewed in the longitudinal direction. In the mower having a front baffle positioned in front of the pair of rotary mowing blades so that an overlapping portion where the rotation areas of the pair of rotary mowing blades overlap is formed and guided to the wind from the pair of rotary mowing blades ,
The front baffle includes a lateral one end side facing the rotation area of one rotary cutting blade of the pair of rotary cutting blades of the front baffle, and a lateral other end side facing the rotation area of the other rotary cutting blade. The boundary of the front baffle is positioned away from the overlapping portion on the side of the cutting blade housing, and the side end portion of the front baffle is directed toward the position where the grass is removed from the overlapping portion on the side of the cutting blade housing. Are configured to be pressed.

本第1発明の構成によると、重合部に前方から入り込もうとする草が前バッフルの横一端側部によって重合部から刈り刃ハウジング横端側に外れた箇所に向けて押圧操作される。これにより、重合部への草の入り込みが発生しにくくなる。そして、草の重合部への入り込みを防止する押圧手段に前バッフルを利用し、草の重合部への入り込みを抑制できる。   According to the structure of this 1st invention, the grass which is going to enter into the superposition | polymerization part from the front is pressed by the horizontal one end side part of a front baffle toward the location removed from the superposition part to the cutting blade housing side end side. This makes it difficult for grass to enter the polymerization portion. And a front baffle can be utilized for the press means which prevents the penetration | invasion to the superposition | polymerization part of grass, and the penetration | invasion to the superposition | polymerization part of grass can be suppressed.

従って、前バッフルを草押圧の手段に利用した簡単な構造によって重合部への草の入り込みを抑制し、刈り残しなどが発生しにくい良好な仕上がりの草刈り作業を冒頭に記した草詰まりを回避して能率よく行うことができ、かつ、安価に得ることができる。   Therefore, the simple structure using the front baffle as a means of pressing the grass suppresses the entry of grass into the overlapped portion, avoiding the clogging of the grass described at the beginning of the mowing work with a good finish that hardly causes uncutting. Can be carried out efficiently and at low cost.

本第2発明は、本第1発明の構成において、前記前バッフルに、前バッフルの下端部から刈り刃ハウジング後方向きに延出した底板を備えてある。   According to a second aspect of the present invention, in the configuration of the first aspect of the invention, the front baffle includes a bottom plate extending from the lower end of the front baffle toward the rear of the cutting blade housing.

本第2発明の構成によると、前バッフルの横一端側部によって押圧操作された草が、前バッフルの横一端側部を通過した後、底板によって上方から押圧操作される。これにより、前バッフルの横一端側部によって押圧された草は、前バッフルを通過した後にも倒伏姿勢を長く維持し、重合部により入り込みにくくなる。   According to the configuration of the second aspect of the invention, the grass pressed by the side end of the front baffle is pressed from above by the bottom plate after passing through the side end of the front baffle. Thereby, the grass pressed by the lateral one end side part of the front baffle maintains the lying posture for a long time even after passing through the front baffle, and becomes difficult to enter by the overlapping part.

従って、草の重合部への入り込みがより発生しにくく、刈り残しなどが一層発生しにくい良好な仕上がりの草刈り作業を行うことができる。   Accordingly, it is possible to perform a mowing operation with a good finish in which the grass is less likely to enter the superposed portion and the uncut portion is less likely to occur.
