Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for disposing a transversal conversion case in a transplanting machine such as a rice transplanter. 2. Description of the Related Art Generally, in this seed transplanter, a seedling table on which seedlings to be planted are set is traversed in synchronization with the timing of scraping of a planting arm. In this case, it is necessary to adjust the lateral feed amount of the seedling mounting table in accordance with the working conditions such as the type of seedling and the number of seedlings. Therefore, in the related art, the traverse amount adjustment has been realized by interposing a traverse amount conversion gear body which can be replaced with a gear body having a different number of teeth in a power transmission mechanism leading to the traverse mechanism. However, in the prior art, the traverse feed conversion case in which the traverse feed conversion gear body is mounted is disposed at a position near the center of the planter case, so that the traverse feed conversion case is planted when adjusting the traverse feed amount. It is necessary to replace the gear body in such a way as to sink into the part, and there is a problem that workability is remarkably inferior. SUMMARY OF THE INVENTION The present invention has been made in view of the above-described circumstances, and aims to provide a structure for disposing a traversing conversion case in an implanting machine that can eliminate these disadvantages. A planting section drive shaft for transmitting power to a planting mechanism is horizontally provided in a planting work section connected to the rear of the traveling machine so as to be able to move up and down, and the planting section drive shaft is provided. Power of
In a riding type transplanter, which is distributed to a transverse feed shaft of a seedling platform transverse feed mechanism via a transverse feed amount converting gear body capable of converting a transverse feed amount by replacement with a gear body having a different number of teeth,
The planting section drive shaft is installed, and engine power from the traveling machine body is supplied to the planting section drive shaft.
A drive case that supports the input shaft for inputting , a planter case to which the planting mechanism is assembled, and a traverse conversion case in which the traverse conversion sprocket is mounted are formed, and one of the right and left sides of the drive case is formed. At one end, a transverse feed conversion case is provided via a planter case, and is exposed outside the planter case.
While the traverse feed case is configured to be able to convert the traverse feed amount,
Insert the traverse feed shaft between the boss protruding from the other end of the drive case and the traverse feed conversion case.
It is characterized by being pivotally supported . According to the present invention, the workability in adjusting the traversing amount can be remarkably improved. Next, an embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a planting work unit which is connected to a rear part of a traveling machine of a riding type rice transplanter so as to be able to move up and down, and the planting work unit 1 moves left and right to a work unit frame 2 and the work unit frame 2 side. A seedling mounting table 3 that is freely supported, a planting arm 4 that scrapes unit planted seedlings from the lower end of the seedling mounting table 3 to plant the seedlings on a rice field, and a float that is provided at the lower end of the working unit frame 2 so as to be swingable up and down. 5 and the like, all of which are conventional. Reference numeral 6 denotes a drive case fixed to the upper end of the working unit frame 2 in the left-right direction. The drive case 6 supports an input shaft 7 in the front-rear direction. A power distribution shaft 8 facing the direction is provided. The input shaft 7 receives engine power from the machine body via a drive shaft (not shown) and transmits the input power to a power distribution shaft 8 via a bevel gear transmission 9. Reference numeral 10 denotes a planter case which is assembled to the left and right ends of the drive case 6. A left and right planter shaft 11 is supported at the leading end of each of the left and right planter cases 10 in a penetrating manner. The planting arm 4 is assembled to the left and right protruding ends of the planter shaft 11 to form a four-row planting mechanism. The planting arm 4 is configured to perform planting operation by motive power transmitted from the sprockets 12 provided at both right and left ends of the power distribution shaft 8 to the planter shaft 11 via the transmission chain 13. On the other hand, reference numeral 14 denotes a transverse feed shaft having a spiral feed groove 14a formed on the outer periphery thereof. The transverse feed shaft 14 is juxtaposed with the power distribution shaft 8 in a juxtaposed manner. In other words, the traverse feed shaft 14 includes a boss 6a integrally projecting from the left end of the drive case 6 and a traverse conversion case 15 assembled to the right end of the drive case 6 via the planter case 10. It is pivoted between. Incidentally, in the lateral feed conversion case 15, the right end of the power distribution shaft 8 penetrating through the right planter case 10 and the right end of the lateral feed shaft 14 are provided. Power is transmitted to the lateral feed shaft 14 by the transmission chain 16 without passing through an intermediate shaft such as a vertical feed shaft as in the related art. It has become. Further, reference numerals 17 and 18 denote first and second conversion sprockets on which the transmission chain 16 is suspended. Each of the conversion sprockets 17 and 18 is a right end of the power distribution shaft 8 and a right end of the transverse feed shaft 14. Are mounted so as to be rotatable integrally with each other. By replacing the conversion sprockets 17 and 18 with ones having different numbers of teeth, the lateral feed amount of the seedling mounting table 3 described later can be converted. It is like that. Reference numeral 19 denotes a cover that closes the opening of the lateral feed conversion case 15. Further, reference numeral 20 denotes a slide piece which meshes with the lateral feed shaft 14 in an external fitting manner. The slide piece 20 is connected to the seedling mounting table by a connecting plate 21 without using a slide bar as in the related art. 3 directly. Then, the rotation-restricted slide piece 20 is configured to laterally feed the seedling mounting table 3 based on a reciprocating left and right movement accompanying one-way rotation of the lateral feed shaft 14. Reference numeral 22 denotes an elastic bellows boot that covers the transverse feed shaft 14. On the other hand, reference numeral 23 denotes a vertical feed mechanism provided on the seedling mounting table 3. The vertical feed mechanism 23 includes a pair of upper and lower rollers 24, a belt 25 suspended between the rollers 24, and a lower roller 24. The seedling contact surface of the belt 25 is moved downward by a predetermined amount as the feed lever 26 is pushed up by a feed lever 26 or the like which is connected via a ratchet mechanism (not shown) for restricting reverse feed. The seedlings set on the mounting table 3 are vertically fed downward. The vertical feed lever 27 for intermittently pushing up the feed lever 26 each time the seedling mounting table 3 moves forward is provided with the above-mentioned vertical feeding lever 27. The horizontal feed shaft 14 is integrally rotatably mounted on the left end portion. That is, the horizontal feed shaft 14 is also used as the vertical feed lever shaft without providing a particularly vertical feed lever shaft as in the related art. In the embodiment of the present invention configured as described above, the conversion sprocket 17 capable of changing the lateral feed amount of the seedling mounting table 3 by replacing the sprocket with a different number of teeth,
Reference numeral 18 is installed in the traverse conversion case 15. The traverse conversion case 15 is assembled via a planter case 10 to one end of the drive case 6 in which the power distribution shaft 8 is mounted. That is, the lateral feed conversion case 15 can be disposed at least outside the planter case 10. Therefore, when adjusting the lateral feed amount, there is no need to perform an extremely poor workability adjusting operation such as exchanging the lateral feed conversion sprockets 17 and 18 so as to sink into the planting work section 1 as in the conventional case. , Planting work unit 1
The traverse adjustment can be performed very easily only by removing the cover 19 of the traverse conversion case 15 exposed on the outer side of the case. As a result, the workability of the traverse adjustment in the rice transplanter can be remarkably improved. . In summary, since the present invention is constructed as described above, the traversing amount converting gear body capable of converting the traversing amount by exchanging with a gear body having a different number of teeth. While the power is transmitted to the seedling platform lateral feed mechanism via the traverse feed conversion case, the traverse conversion case housing the traverse conversion gear body is provided at one end of the drive case housing the planting unit drive shaft. It is arranged via a planter case. That is, the traverse conversion case is disposed in an exposed state at least outside the planter case. Therefore, in the traverse amount adjustment, the traverse feed case is sunk into the planting work section as in the related art. Without replacing the conversion gear body, the traverse feed amount can be adjusted extremely easily only by replacing the traverse conversion gear body in the traverse conversion case that is exposed outside the planter case. As a result, the workability of adjusting the lateral feed amount in the transplanter can be significantly improved.
