These sliding members have a channel-shaped cross-sectional shape, and are provided by covering the sliding rails with the opening of the cross section downward.

[Patent Document 1] Japanese Utility Model Application Publication No. 6-5406

With such a configuration, when the sliding member is removed from the sliding rail at the time of maintenance, the moving member main body side cannot be moved from the direction perpendicular to the sliding rail, that is, from the seedling loading surface toward the traveling device main body side. Either by moving one of the moving rails and separating it, once the sliding member is lifted from the sliding rail and then moved in the direction orthogonal to the sliding rail, or by moving the sliding member to the longitudinal end of the sliding rail. It was necessary to remove the sliding member with respect to the sliding rail. As a result, there was a fear that time and human burden would be increased in all the work to start maintenance.

The present invention has been made in view of the above problems, and an object thereof is to provide a non-working machine that is easy to maintain.

The 1st characteristic structure of this invention exists in the following points.

By this structure, since the vertical wall surface of the sliding member is arrange | positioned at the side surface on the opposite side to the side facing the said seedling loading stand of a sliding rail, a seedling loading stand is removed from a sliding rail in the state which attached the sliding rail. If it is to be spaced apart (that is, to change the posture from the working posture to the maintenance posture), the vertical wall surface and the sliding rail come into contact. Thus, the seedling loading table can be reliably maintained in the working posture.

On the other hand, at the time of switching to the maintenance posture, the sliding member can be removed by moving the sliding member toward the seedling loading table without the vertical wall surface and the sliding rail contacting each other.

As a result, the posture change to a maintenance posture can be easily performed, taking the structure which can hold | maintain a seedling loading stand reliably in a work posture.

According to a fourth aspect of the present invention, the sliding member includes a first sliding member and a second sliding member, and each of the first sliding member and the second sliding member has a vertical wall surface. One of the two vertical wall surfaces is disposed along the side opposite to the side facing the seedling loading stand of the sliding rail, while the other side faces the seedling loading stand of the sliding rail. It is arrange | positioned along the side surface, and is a point which clamps the said sliding rail in two said vertical wall surfaces.

With the above-described configuration, the sliding rail is fitted in the vertical wall portions provided in each of the two sliding members in the working posture. As a result, posture maintenance to a working posture becomes more certain.

The 5th characteristic structure of this invention is that the cover member is provided between the said apparatus main body and the said seedling loading stand.

By this structure, since the cover member is provided between the said apparatus main body and the said seedling loading stand, the surface which faces the apparatus main body of the seedling apparatus provided with the seedling loading stand etc. by preventing the mud splashing from a rear wheel etc. with a cover member. It is possible to prevent the adhesion of mud to an operation mechanism or the like provided to the apparatus.

A function of guiding the upper portion of the seedling placing table 17 to be slidably movable is provided.

Next, the slide support structure in the lower side of the seedling loading stand 17 is demonstrated. 3 to 5, the support member 17B is similarly installed and fixed to the left and right width ends below the guide frame 17A on the back side of the seedling loading table 17 toward the traveling device main body. At the same time, the sliding rail 14 described above is disposed below the supporting member 17B. As shown in Figs. 16 to 21, the first sliding member 15A is disposed on the upper side and the second sliding member 15B is disposed on the lower side so as to sandwich the supporting member 17B from the upper and lower sides. The head bolt is embedded in the second sliding member 15B, and the state bolt 16 which protrudes the screw part upward is provided, and the state bolt 16 is attached to the first sliding member 15A and the supporting member. The support member 17B and the 1st, 2nd sliding member 15A, 15B are comprised so that slide movement is possible so that it may penetrate through 17. As shown in FIG. The second sliding member 15B is located between the supporting member 17B and the sliding rail 14 so as to be supported by the sliding rail 14.

16-21, the slide guide plate 14A is screwed on the upper surface of the sliding rail 14, and is comprised so that the 2nd sliding member 15B may be loaded and guided. The second sliding member 15B is an elongated member having a cross-sectional angle, and is provided with oil supply pipes 15b standing up at both ends thereof, and is provided by arranging the vertical wall surface 15a of the elongated member having a cross-sectional angle at the seedling loading side. The bottom surface of the lower part of the pipe 15b is granulated upward, and it is formed in the structure used as a storage space a of lubricating oil.

As shown in Figs. 16 and 21, the sponge plate 18 can be sandwiched and used in the storage space a, and a constitution that enhances the holding capacity of the lubricating oil may be adopted.

As shown in Figs. 16-18, although the oil supply pipe 15b is provided in the 2nd sliding member 15B, a seedling loading surface in order to supply lubricating oil (grease) through this oil supply pipe 15b. The supply pipe 17a and the lubrication pipe 15b are connected to the rubber hose 19 to the partition wall 17F which divides into the partition wall 17F, and the oil supply operation | work from the seedling loading surface side of the seedling loading stand 17 can be performed.

In this way, the number of parts can be reduced by providing the oil supply pipe 15b to the second sliding member 15B. Moreover, since the clearance gap is provided between the sliding member 15 and the back surface of the seedling loading stand 17, blockage of a seedling etc. can be avoided in the meantime, and the lubrication of oil is less likely to be impaired.

As shown in Figs. 16 and 17, elastic protrusions 15c and 15c are formed between the left and right oil supply pipes 15b in the second sliding member 15B and the state bolts 16 penetrating up and down. It penetrates through the through-holes 17b and 17b formed in the support member 17B from below, and press-contacts the edge part of the through-holes 17b and 17b, and firmly installs the 2nd sliding member 15B. The structure which exhibits the function to make is employ | adopted.

The 1st sliding member 15A is demonstrated. As shown in Figs. 18, 19, and 21, the first sliding member 15A is an angled short member, which loads the upper wall 15d onto the support member 17B, and at the same time, the vertical wall surface 15e. Along the outer surface facing the traveling device main body 5 side of the sliding rail 14, and slightly bends the lower end of the vertical wall surface 15e to engage with the concave surface portion 14a of the sliding rail 14. The structure which raises the engagement degree of the sliding rail 14 is employ | adopted.

As shown in Figs. 18, 19 and 21, the notch 15f is formed in the top wall 15d of the first sliding member 15A in the direction perpendicular to the sliding direction. The coupling portion 15f has a crank shape in plan view. The crank-shaped cutout portion 15f includes a first guide cutout portion 15g that extends from the inner end portion on the seedling loading side of the upper wall 15d to the middle portion toward the outer end portion corresponding to the outer surface of the sliding rail 14. It is formed in the state which communicates with the 2nd guide cutout part 15h formed in the state along the sliding direction from the intermediate part used as the terminal part of the 1st guide cutout part 15g. A third induction cutout 15k parallel to the first induction cutout 15g is formed from the end of the second induction cutout 15h to the outer end described above, and these three induction cutouts ( 15c, 15h, 15k) form the crank-shaped notch 15f.

As shown in Fig. 19 and Fig. 21, by forming the first guide cutout portion 15g in this way, even when the mounting bolt 16 for installation is installed, the first guide cutout portion 15g is used instead of the mounting bolt 16. The sliding member 15A can be pulled out on the outer end side and charged from the outer end toward the inner end, and the installation and removal are easy. The first sliding member 15A is formed by forming the bolt insertion through-hole H through which the installation state bolt 16 is inserted into the second guide cutout 15h and fastening and fixing at the bolt insertion through position. The installation fixed state is stabilized without escaping to the outer end side.

Ribs 15m and 15m are formed outside the intersections of the second guide cutout 15h and the first and third guide cutouts 15g and 15k, respectively, and the bolts of the second guide cutout 15h are inserted. Even if the first sliding member 15A is to be moved along the second guide cutout 15h with the state bolt 16 installed in the penetrating portion H, it is provided in the state bolt 16. One nut 16A contacts the rib 15m, and the positional change of the first sliding member 15A is prevented.

With the above structure, the installation and removal of the first sliding member 15A and the like can be easily performed, and it is not suddenly dropped.

The horizontal feed mechanism B will be described. As shown in Figs. 3, 5 and 14, the screw shaft 20 serving as the drive shaft is extended from the planting feed case 8 which receives the planting power from the engine 3 side toward one side in the transverse direction. At the same time, the extended end is supported by the bracket 21. In the intermediate position of the screw shaft 20, the movable body 22 which accommodated the coma member 22A couple | bonded with the spiral groove 20A formed in the screw shaft 20 is externally fitted. The movable body 22 reciprocates along the shaft center of the screw shaft 20 by rotating the screw shaft 20 around the shaft center.

The connecting member 23 which connects the movable body 22 and the seedling loading table 17 is demonstrated. 3, 5, and 14, the mounting table 17C is fixed to the rear surface of the seedling mounting table 17, and the first connecting member 23A is extended from the mounting table 17C. A hooked long hole 23a is formed in the tip portion of the first connecting member 23A. On the other hand, the 2nd connection member 23B is provided in the movable body 22, and the engaging pin 23b couple | bonded with the said long hole 23a is provided in the front-end | tip of this 2nd connection member 23B.

With the above configuration, when the screw shaft 20 is rotated around the shaft center, the movable body 22 reciprocates, and the seedling placing table 17 connected to the movable body 22 by the connecting member 23 reciprocates. .

Here, the connecting member 23 is constituted by the first connecting member 23A and the second connecting member 23B. Further, the seedling loading table 17 is switched to the non-working position while the hooked long hole 23a and the coupling pin 23b are maintained in a connected state between the connecting member 23 and the screw shaft 20 as the drive shaft. This is called an allowable mechanism C.

The seedling extraction part is demonstrated. As shown in Fig. 20 (a) to (c), the seedling outlet 17D is formed at a portion where the planting hook 13A of the seedling mechanism 13 in the seedling loading table 17 passes. The seedling extraction guide 17E is formed downward from the seedling extraction port 17D. The seedling taking out guide 17E consists of a pair of left and right guide members 17c and 17c, and the chamfer 17d is shown at the upper end of the guide members 17c and 17c as shown in Figs. 20B and 20C. ) To prevent damage to the seedlings.

As shown in FIG.4 and FIG.5, the vertical feed mechanism E which feeds the mat type seedling on the seedling loading surface toward the seedling extraction port 17D above the seedling extraction port 17D is provided. The longitudinal conveyance mechanism E installs the drive wheel body 24 in the lower end side of the seedling loading stand 17, and installs the driven wheel body above the drive wheel body 24, and draws it over the both wheel body 24. The conveyance belt 26 is comprised. A large number of projections are formed on the surface of the seedling conveyance belt 26, and the projections lock the mat-shaped seedlings so that the mat-shaped seedlings can be efficiently moved.

6-8, the drive arm 27 as a drive member is provided in the seedling feed shaft 25 similar to the drive wheel body 24, and the drive arm 27 is attached to the winding spring 28. As shown in FIG. By returning to a standby position by this, it is comprised so that it may loosely rotate at the time of return by a one-way clutch (not shown).

On the other hand, from the position different from the projecting position of the screw shaft 20 of the planting feed case 8, the output arm as an output member which protrudes the output shaft 29 toward the left-right direction and always rotates to the projecting part of the output shaft 29 ( 30) install.

With the above structure, when the screw shaft 20 is rotated and the seedling loading stand 17 is moved horizontally, the output arm 30 and the drive arm 27 in the horizontal movement stroke edge part of the seedling loading stand 17 are carried out. ), The position in the lateral movement direction coincides, and the driving arm 27 is driven by the output arm 30 by a predetermined rotation range against the spring biasing force. When driven by this constant rotation range, the seedling conveyance belt 26 is driven by driving the drive wheel body 24 by the one-way clutch. As a result, the mat-type seedlings are fed toward the seedling outlet 17D by a predetermined amount.

Next, the holding mechanism F for holding the drive arm 27 in the standby position will be described. 5 to 11, the regulation arm 31 is loosely rotatably provided together with the driving arm 27 on the seedling feed shaft 25 of the driving wheel body 24. As shown in FIG. 31 A of locking heads are provided in the upper surface of the regulation arm 31, the bracket 27A is also provided in the upper surface of the drive arm 27, and the adjustment screw 32 is provided in the bracket 27A, The distal end portion projecting downward from the bracket 27A of the adjustment screw 32 is in contact with the locking head portion 31A of the regulating arm 31.

In this way, since the adjusting screw 32 is only in contact with the regulating arm 31, when the driving arm 27 is driven by the output arm 30, the driving arm 27 is moved from the regulating arm 31. Since it is only in a spaced apart state, the regulating arm 31 has no effect during longitudinal conveyance.

6 to 9, the rear surface of the seedling loading table 17 at the position between the two longitudinal feed mechanisms E and E at the intermediate height position between the drive wheel body 24 and the driven wheel body. The support bracket 35 is attached to the support bracket 35, and the support bracket 35 is configured to support the pulling operation tool 34 as the holding mechanism F. The pulling operation tool 34 forms an arc-shaped grip portion 34A at the upper end portion, and forms a hook-type latch portion 34B at the lower end portion, and between the grip portion 34A and the hook-type latch portion 34B. The flange portion 34C is formed.

As shown in Figs. 9 to 11, the hook-type locking portion 34B of the pulling operation tool 34 is passed through the lateral hole 31a formed in the locking head portion 31A, and the hook-type locking portion 34B. ) Is coupled to the locking head portion 31A. In this manner, the hook-type locking portion 34B is coupled to the locking head portion 31A, so that the pulling operation tool 34 having the arc-shaped holding portion 34A is lifted as shown in FIG. The lower limit arm 31 swings and raises. In this case, since the driving arm 27 makes the adjustment screw 32 contact the engaging head portion 31A of the regulating arm 31, the driving arm 27 receives the upward swing displacement of the regulating arm 31 to operate the interlocking swing upward. .

As a result, the drive arm 27 comes into contact with the output arm 30 to escape from the operating range under the driving force and retreat to the standby position. Here, the regulation arm 31 and the pulling operation tool 34 are called the holding mechanism F which holds the drive arm 27 in a standby position.

As shown in Fig. 12, in the support bracket 35 provided to support the pulling operation tool 34, a discharge hole 35A having integrally formed the wide portion 35a and the narrow portion 35b is formed. The width of the wide portion 35a is wider than the diameter of the flange portion 34C of the pulling operation tool 34, and the width of the narrow portion 35b is of the flange portion 34C of the pulling operation tool 34. The width is narrower than the diameter and narrower than the diameter of the rod-shaped portion between the flange portion 34C and the hook-type grip portion 34A of the pulling operation tool 34.

As shown in Fig. 7, in the state where the rod-shaped portion is located in the discharge hole 35A, the driving arm 27 is in a position in which the output arm 30 can be contacted, as shown in Fig. 8; From the state, the pulling operation tool 34 is raised to move the flange portion 34C through the wide portion 35a to move the flange portion 34C toward the narrow portion 35b, and to the corner portion of the narrow portion 35b. By contact-loading, the pulling operation tool 34 can be supported by the support bracket 35. In this case, the restricting arm 31 is lifted by the lifting operation tool 34, whereby the driving arm 27 is held in the standby posture not in contact with the output arm 30 as described above.

Next, the seedling extracting amount adjusting mechanism D will be described. 5 to 9, the support 36 supporting the sliding rails 14 is mounted on the side surface of the planting transmission case 11 so as to be movable up and down, and at the upper end position of the support 36. An engaging recess 36A is provided. Although the adjustment arm 37 which engages with the engagement recessed part 36A is provided, it connects the adjustment arm 37 to the seedling taking-out adjustment control tool, although it is not shown in figure, and the support base 36 is moved up and down with the adjustment arm 37. Move the whole of the seedling loading stand 17 up and down with the sliding rail 14 to change the relative height of the seedling loading stand 17 and the planting transmission case 11, and take out the seedling of the planting hook 13A. It is comprised so that the relative position of the seedling taking-out port 17D with respect to a trajectory can be changed, and the seedling taking-out amount can be adjusted.

5 to 9, the interlocking arm 38 which swings integrally with the adjusting arm 37 is mounted on the same axis as the adjusting arm 37, and the amount of seedling extraction of the adjusting arm 37 is adjusted. The interlocking arm 38 is interlocked with the oscillating operation for the interlocking motion, and the interlocking arm 38 is configured to oscillate the regulating arm 31. Then, the driving arm 27 is similarly shaken by the rocking of the restricting arm 31.

For example, in order to reduce the seedling extraction amount, when the seedling loading stand 17 is lifted, as shown in FIGS. 6 and 7, the linkage arm 38 is rotated by the rotational operation of the adjustment arm 37. The regulating arm 31 rotates by a predetermined angle, and moves the driving arm 27 slightly above the standby position, and the position becomes a new standby position.

Then, since the contact starting position (standby position) a with the output arm 30 of the drive arm 27 driven by the output arm 30 is displaced to a ', by that much The swing angle becomes small, thereby decreasing the longitudinal feed amount.

With this configuration, the vertical feed amount can be adjusted in conjunction with the seedling extraction amount adjustment.

Next, the structure which switches to the maintenance posture of the seedling loading stand 17 is demonstrated. As shown in FIG. 5, although the bracket 12A which installs the guide roller 12C in the upper end part of the support pillar 12 is provided, normally, the bracket 12A is upwardly pivoting pin 12a. The lower side is fixed with the bolt 12b.
