Embodiment
Embodiment:
as Fig. 1, Fig. 2 and shown in Figure 3, the transplanting section of rice transplanter, comprise rice transplanting transmission case 1, the rice transplanting transmission case rotates by the rotary drive case 2 that the rotary drive case drive shaft that is arranged on its both sides is arranged on its both sides, rear portion, the rotary drive case drives transplanting arm 3 and carries out work, described rice transplanting transmission case 1 comprises housing, and be arranged on rice transplanting clutch in housing, described rice transplanting clutch comprises initiatively clutch block 12 and passive clutch block 13, being set on rotary drive case driving shaft 11 of the free to rotate and axial restraint of described active clutch block 12, described passive clutch block 13 is located on rotary drive case driving shaft 11 by spline housing, and can horizontally slip vertically.
The rear portion of described passive clutch block 13 is provided with spring 14, and described spring is arranged between passive clutch block 13 and spring washer, with passive clutch block 13 push to initiatively clutch block 12 and with its interlock, initiatively clutch block 12 drives passive clutch blocks 13 and rotates.Described passive clutch block 13 peripheries are provided with the inclined-plane of gradually opening.
Described passive explant 13 can make it separate with active clutch block 12 by on-of pin 4, and described on-of pin 4 is inserted in casing from the outside of rice transplanting transmission case, perpendicular to the axis direction of passive clutch block.
When the needs clutch block separates, push on-of pin 4 to passive clutch block 13 by the spring force that is fixed on the rice transplanting mechanism housing, when passive clutch block 13 inclined-plane lowest parts turn to the position of on-of pin, on-of pin 4 can be inserted into the lowest part on inclined-plane, along with the rotation of passive clutch block, passive clutch block 13 is pushed open.
As shown in Figure 4, the back side of described passive clutch block 13 is provided with a circle groove 131, and described groove 131 can make the front end of spring 14 be embedded in passive clutch block 13 grooves 131, makes the back side of passive clutch block 13 and the hypotelorism of rice transplanting transmission case inwall.In addition, when passive clutch block is in active clutch block released state, almost fit with rice transplanting transmission case inwall in the back side of passive clutch part, and the spring after compression can wholely be housed in the groove 131 at the passive clutch block back side.When passive clutch block and the interlock of active clutch block, the axially-extending line of on-of pin and spring intersect, and compare with original rice transplanting transmission case, and spring is arranged on the position of more keeping right, and the integral body of rice transplanting transmission case is narrower.
Like this, can realize shortening the spacing of passive clutch block 13 backs and rice transplanting transmission case inwall in the situation that do not shorten passive clutch block length, can not affect the stability that coordinates between passive clutch block 13 and rotary drive case driving shaft 11.In rotation, passive clutch block can too not rock.It is narrower that thereby the width of rice transplanting transmission case also can design.
As shown in Figure 2, described rotary drive case 2 is provided with transplanting arm driving shaft 21, transplanting arm driving shaft 21 is inserted in transplanting arm 2 housings by stretching out in rotary drive case 2, and rice transplanting driving shaft 21 is fixed on the drive plate of transplanting arm 3 inboard housing outer surface by driving, drives transplanting arm and rotates.The front end of transplanting arm driving shaft is inserted in transplanting arm 3 housings, makes transplanting arm 3 more stable in work.
Be arranged with sealing ring 31 on the described transplanting arm driving shaft 21 that is positioned at the transplanting arm housing, described sealing ring 31 is arranged on the position near rice transplanting wall housing outer surface, thereby when making rice transplanter work, muddy water can be not too much penetrate in transplanting arm, cause that transplanting arm driving shaft 21 gets rusty, cause its transplanting arm driving shaft and transplanting arm stuck.
As Fig. 2 and shown in Figure 5, the central gear fixture of described rotary drive case 2 and the sealing contact member of rice transplanting transmission case 1 are fixing by three bolts 5 that are connected with rice transplanting transmission case 1, described bolt 5 is arranged on the radially surrounding of rotary drive case driving shaft 11, and away from rotating driveshaft.From rotary drive case driving shaft 11 axially, three bolts 5 are positioned at the outside of the sealing 22 of rotary drive case 2, and from transmission case driving shaft 11 radially, the sealing 22 of the rear end of bolt 5 and rotary drive case 2 is overlapping.Such structure makes rice transplanting transmission case 1 narrower than originally, and bolt 5 can not interfered with the sealing 22 of rotary drive case 2.
Simultaneously the described position that bolt 5 is set should be as far as possible away from the peristome 15 of rice transplanting transmission case 1, because the casing of rice transplanting transmission case is to form by die casting, the wall thickness of the rice transplanting transmission case that cast forms thickens to the bottom gradually from peristome, so bolt 5 is arranged on the position that keeps away oral area, the wall section of rice transplanting transmission case 1 that can guarantee set bolt is thicker, bolt fixing more stable can not rock.
Fig. 2 and Fig. 6, the leading section of described rice transplanting transmission case 1 is by bolt 6a, 6b is fixed on rice transplanting frame 7, bolt 6a, 6b respectively has two, is separately positioned on the mount pad 16 that is positioned at four jiaos of rice transplanting transmission case leading sections, and the described bolt 6a that is positioned at top mount pad 16 is bolt, bolt is arranged on observes when top convenient operation person installs the rice transplanting transmission case, thereby fast bolt is penetrated in locating hole.
Bolt comprises location division 61 and threaded portion 62, location division 61 is located in the locating hole of rice transplanting frame 7 of a side adjacent with rice transplanting transmission case 1, the screw apart from a rice transplanting transmission case side far away is passed in the threaded portion 62 that is arranged on the bolt front end, and is fixed by nut.
Described location division 61 is less with the gap of corresponding screw, and after the rice transplanting transmission case was fixed, the rice transplanting transmission case can not produce because the excesssive gap between bolt and screw occurs displacement.
Be only below concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.In addition to the implementation, the utility model can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, within all dropping on the utility model scope required for protection.
