における図示しないキヤビン内に設けたグリース
供給装置に接続してある。 A spray nozzle 8 is provided on the tip side of the guide cell 3 in the vicinity of the sleeve chuck 6, facing the rod threaded portion 5a, and the spray nozzle 8 has a first hose 9 for supplying air and a hose 9 for supplying grease. The second hose 10 is connected, and the first and second hoses 9 and 10 are connected to the vehicle body 2.
It is connected to a grease supply device provided inside the cabin (not shown).
該グリース供給機構は第３図に示すように、エ
ア源１１とグリースレザーバ１２とを備え、エア

ースレザーバ１２が接続されかつ第２ホース１０
が接続してある。 As shown in FIG. 3, the grease supply mechanism includes an air source 11 and a grease reservoir 12, and the discharge side of the air source 11 is connected to an inlet port 15a of a solenoid valve 15 via an air filter 13 and a lubricator 14. , the outlet port 15b of the solenoid valve 15 is connected to the first hose 9 via the pressure reducing valve 16 and to the air pump 18 via the speed regulating valve 17, and the pressure chamber 18a of the air pump 18 is connected to the grease reservoir. 12 is connected and the second hose 10
is connected.
しかして、通常作業時には電磁弁１５がドレー
ン位置となつてエア源１１のエア圧が供給され
ないからグリースは噴射されない。 During normal operation, the solenoid valve 15 is in the drain position and air pressure from the air source 11 is not supplied, so no grease is injected.
また、電磁弁１５のソレノイド１５ｃを励磁す
ると供給位置となつてエアポンプ１８及びスプ
レイノズル８にエアが供給され、エアポンプ１８
が駆動してグリースがスプレイノズル８に圧送さ
れエアと混合された後にスプレイノズル８より噴
射されてロツドネジ部１５ａに塗布される。 Furthermore, when the solenoid 15c of the solenoid valve 15 is energized, it becomes the supply position and air is supplied to the air pump 18 and the spray nozzle 8.
is driven, the grease is force-fed to the spray nozzle 8, mixed with air, and then sprayed from the spray nozzle 8 to be applied to the rod threaded portion 15a.
この時、電磁弁１５のソレノイド１５ｃ通電時
間（エアの供給時間）はエアポンプ１８の作動時
間（グリース圧送時間）よりも長くなり、グリー
ス供給終了後にエアがスプレイノズル８より空吹
き（アフタブロー）されるようにしてあるので、
グリースの後だけを防止できる。 At this time, the energization time (air supply time) of the solenoid 15c of the solenoid valve 15 becomes longer than the operation time (grease pumping time) of the air pump 18, and air is blown from the spray nozzle 8 (after blow) after the grease supply is finished. Because it is set like this,
Can only be prevented after grease.
そして、アフタブロー終了後にソレノイド１５
ｃが消磁されてドレーン位置となり、エアポン

間の時間はグリースの硬さ外気温度にもよるが約
２〜10秒程度必要である。 Then, after the after blow, solenoid 15
c is demagnetized to the drain position, the air in the air pump 18 is discharged to the atmosphere by the spring 18b, and during this discharge time, grease is sucked into the pressure chamber 18a from the grease reservoir 12. The time required during this time depends on the hardness of the grease and the outside temperature, but approximately 2 to 10 seconds is required.
以上で１回のグリース噴射が終了し、５〜６分
の時間間隔で間欠的に数回繰り返す。 This completes one round of grease injection, which is repeated several times intermittently at intervals of 5 to 6 minutes.
なお、ソレノイド１５ｃの励磁スイツチは運転
室内のコントロールボツクス内に設けてあると共
に、ソレノイド１５ｃの励磁時間（アフタブロー

で調整できるようにしてある。 The excitation switch for the solenoid 15c is provided in a control box in the driver's cab, and the excitation time (after-blow time) of the solenoid 15c can be adjusted using a timer provided in the control box.
以上の様であるから、ソレノイド１５ｃを励
磁・消磁操作するとの簡単・容易な操作でドリフ
タ４のロツドネジ部５ａにグリースを塗布でき
る。 As described above, grease can be applied to the rod threaded portion 5a of the drifter 4 with a simple and easy operation of energizing and demagnetizing the solenoid 15c.
また、スプレイノズル８はエアで清掃されるか
ら清掃が不要であると共に、スプレイノズル８の
出口に固着したグリースをエアで吹飛ばしでき
る。 Further, since the spray nozzle 8 is cleaned with air, cleaning is not necessary, and the grease stuck to the outlet of the spray nozzle 8 can be blown away with air.
また、運転席内からグリース塗布作業が行なえ
る。 Additionally, grease application work can be performed from inside the driver's seat.
また、グリースはグリースレザーバ１２内に設
けてあるので、グリースの酸化・劣化が防止でき
る。 Further, since the grease is provided in the grease reservoir 12, oxidation and deterioration of the grease can be prevented.
また、グリースレザーバをエンジンルーム内に
設置すればエンジンの熱でグリースが暖められエ
アポンプ１８内へのグリース吸込み性が良好とな
る。 Moreover, if the grease reservoir is installed in the engine room, the grease will be warmed by the heat of the engine, and the suction of the grease into the air pump 18 will be improved.
