Definitions

  • FIG. 7 is a partial plan view of a plane around a communication hole 174.
  • the gear is shifted in the mission case 40 and left and right Is transmitted from the transmission shaft case 33 extending to the rotary case 35 via a plurality of planting transmission cases 34 extending rearward.
  • the rotary case 35 rotates, and a pair of planting claws 36 attached to the rotating rotary case 35 take out seedlings alternately from the mat on the seedling mount 37 and plant the seedlings in the field.
  • the spool position of the switching valve 160 linked to the steering handle 25 is switched and hydraulic oil is supplied to the hydraulic motor 161, and the rotational power to which torque is applied by the hydraulic motor 161 is generated.
  • the front wheels are steered through the rotation shaft 109, the speed reduction mechanism 124, the pitman arm shaft 111, the pitman arm 120, and the like.
  • the shafts 64, 65, 66, 67, and 31 are non-immersed transmission shafts disposed above the oil level 153 a, so that the shafts 64, 65, 66, and 67 are operated during the operation of the rice transplanter 1. 31 and the lubrication oil in the oil sump 153 will not be vigorously stirred by these high-speed rotations even if the lubricated parts such as 31 and gears, brakes, clutches, bearings, joints, etc., rotate at high speeds. . Thereby, loss horsepower decreases and the oil temperature rise accompanying stirring resistance is suppressed.
  • the return oil passage 189 formed in the case member (case body 56) of the transmission case 17 allows the hydraulic oil accumulated in the hydraulic continuously variable transmission 19 to flow into the transmission case 17.
  • the hydraulic oil is configured to be returned to the oil reservoir 153, and the hydraulic oil is transferred to the transmission shaft (non-immersed transmission shaft) 65, 67 in the transmission case 17 and the transmission shaft 65 while returning to the oil reservoir 153.
  • -It is comprised so that it may supply to the gear 76 * 77 * 78 * 105 as a to-be-lubricated part accompanying 67, the one-way clutch mechanism 104, the bearing 201 * 202, and the coupling 112 as lubricating oil.
  • the return oil passage 189 is composed of the communication hole 174 and the groove-shaped recess 186 formed in the case member (case body 56) constituting the mission case 17 as described above.
  • the case member (case body 56) is configured using ribs 187 and 188 formed as existing ones.
  • the groove-shaped recess 186 extends from the communication hole 174 to the oil reservoir 153. Therefore, the hydraulic oil that has returned from the housing 73 of the hydraulic continuously variable transmission 19 into the transmission case 17 through the communication hole 174 is contained in the groove-shaped recess 186 configured using the front and rear ribs 187 and 188. And can flow gently into the oil sump 153.
  • the boss portion 213 is disposed along the outer periphery of the right end portion of the PTO transmission shaft 67 immediately below the rear partition portion 204a of the storage rib 204.
  • the bridge rib 212 is suspended from the lower end of the rear partition portion 204a on the rear upper portion 213a of the boss portion 213.
  • An oil hole 215 is provided in the lid body 57 immediately after the boss portion 213. Between the oil hole 215 and the rear upper part 213a of the boss part 213, the bridge rib 214 inclined rearward and obliquely upward is interposed.
  • the communication holes 171 and 172 connected to the elevating hydraulic cylinder 47 are formed through the lid body 57 as shown in FIG.
  • the communication holes 171 and 172 open at the inner side surface 57e of the lid 57 at a position below the oil surface 153a of the oil reservoir 153, as can be seen particularly well in FIG. Therefore, the oil returned from the elevating hydraulic cylinder 47 to the mission case 17 through the communication holes 171 and 172 is not used for lubrication but is returned to the oil reservoir 153 as it is.

Abstract

L'invention porte sur un essieu (64), qui est porté et soutenu par les surfaces internes (56e, 57e) d'un corps principal de carter (56) et d'un corps de couvercle (57), ou à l'intérieur du corps principal de carter (56) et du corps de couvercle (57), constituant des deux côtés le carter de transmission (17). Ledit essieu (64) est situé plus haut que le niveau d'huile (153a) dans le réservoir d'huile (153). Une trajectoire d'huile de retour (189) est placée, celle-ci renvoyant vers le réservoir d'huile (153) l'huile de travail à l'intérieur d'une transmission hydraulique variable en continu (19) qui est montée sur la surface extérieure du corps principal de carter (56). Ladite trajectoire d'huile de retour (189) est formée sur la surface intérieure (56e) du corps principal de carter (56). L'huile de travail dans la trajectoire d'huile de retour (189) peut être délivrée à l'essieu (64) ou à un engrenage (76) associé à celui-ci.
