And the left and right side clutch levers 40 and 41 and the transmission 10 are connected by wires. However, the forward / reverse switching lever 39 and the transmission 10 are connected by a rod. Then, an operator sitting on the driver's seat 31 can easily operate necessary levers, and can appropriately perform traveling, stopping and selection of a traveling direction, fertilization, and the like of the planting machine 1.

  Also, the seed bed 43 (43a, 43b) on which a container or the like containing seeds is placed from the vicinity of the front part of the right and left edges of the seed brazing opening 6 to the outside is rectangular in the horizontal direction. Overhang, and set up a little near the left edge or right edge. In addition, the footrests 44 (44a, 44b) on which the operator's feet are placed are horizontally directed from the vicinity of the center portion of the left and right frame members of the traveling body support frame 4 disposed on the lower side corresponding to the left and right edges, respectively. Overhang in the direction of a small rectangle. Also, in order to prevent dirt, stones, dust, etc., raised by the vertical earthing device 26 from entering the left and right crawler type traveling body 7 inside the left and right frame members of the traveling body support frame 4, As the prevention member 45 (45a, 45b), for example, a rectangular plate material is disposed such that the plate surface is in the vertical direction.

  In addition, a seeding rattle timing sound generator 46 is installed in a part of both traveling bodies 7 installed in the vicinity of the left and right outer sides of the vehicle body 2. Then, the kind of ratchet timing sound generator 46 receives the output from the belt support wheel rotation position indicating means for indicating the rotation position of the driven rear wheel 18 that supports the right crawler belt 16b, for example, and the instruction means. Thus, each time the planting machine 1 moves forward by a certain distance, it comprises sound generating means for informing the seeding timing with sound. At that time, as the belt support wheel rotation position instruction means, for example, an elongated plate body 48 provided with impact projections 47 (47a, 47b) at both ends as shown in FIG. 4 is used, and the plate body 48 is used as the driven rear wheel 18. The center of the plate body 48 and the rear wheel shaft 17b are aligned with each other and fixed to the outer surface. The plate member 48 may be omitted and only the striking projection 47 may be fixed to a predetermined position of the driven rear wheel 18.

  Further, as a sound generating means, for example, a swing hammer in which the center of a long handle 49 is supported by a shaft 50, a rod-like reverse rotation absorbing spring, for example, a coil spring 51 is interposed in the front handle portion, and a hitting head 52 is provided at the tip. 53 and a sound source receiving member 54 that receives the hitting head 52, and the hammer rotating shaft 50 and the sound source receiving member 54 support the front and rear rotating shafts 14 and 17b of the traveling body support frame 4. Stick to the inside of the right outer frame. A return spring, for example, a coil spring 55 is attached to the end of the shaft 50 in order to urge the hammering head 52 of the hammer 53 so as to always contact the sound source receiving member 54. At that time, as shown in FIG. 5, the central portion 56 of the return coil spring 55 is wound around the end portion of the shaft 50, and one end portion 57 of the coil spring 55 is provided near the outer upper edge of the rear handle portion. The other end 59 contacts the receiving projection 60 provided on the inner side of the right outer frame that supports the front and rear pivot shafts 14 and 17b. Further, the rear end of the long handle 49 protrudes into the rotation region of the hitting projection 47.

  Such a self-propelled single-passenger type seedling planting machine 1 can be carried out by directly carrying out the sowing of seeds by hand while the operator is on board and driving it. The work necessary for planting seeds is carried out by cutting the vertical grooves, applying fertilizer from the fertilizer tank 21 with the discharge pipe 20 to the vicinity of the pits and the grooves, and covering the seeds sowed with the earthenware container 32. Can be processed continuously and consistently. Moreover, for example, the size of the planting machine 1 is 2 m, the width is 0.7 m, the total weight is 250 kg, and the total weight is 250 kg, and the price of the product is low. Become.

  When planting seeds or potatoes, for example, an operator gets on and drives, places the planting machine 1 on the edge of the field, and then starts planting. At that time, the operator sits down on the driver's seat 31 and puts both feet on the footrest 44 respectively. As a result, the potato can be struck directly by hand from between both feet through the heel opening 6 of the vehicle body 2 that is wide open to the front. Moreover, when the operator sits down on the driver's seat 31 provided at the rear of the vehicle body, the travel drive engine 9 with the fuel tank 8 and the transmission 10 are installed at the front of the vehicle body 2. A balance can be achieved, and the crawler type traveling body 7 is disposed in the vicinity of the left and right outer sides of the vehicle body 2, so that the stability and straightness of traveling can be ensured.

  Then, if a debris intrusion prevention member 45 is provided in the vicinity of the left and right edges of the seedling opening 6 of the car body 2, soil, stones, and dirt that are raised by the erecting earthenware 26 during traveling. Can smoothly travel without entering the left and right crawler type traveling body 7. In addition, once the traveling direction of the planting machine 1 is set on a flat ground, the operation for correcting the traveling direction by hand is not required much during traveling. Therefore, both hands can devote themselves to sowing seeds. On the other hand, the planting machine tends to slip off on sloping ground, and it is often necessary to correct the direction of travel, so you have to concentrate your attention on the driving, and the power to focus on the seeding work is inevitably reduced. .

  Therefore, when a V-shaped ridge with a seed ridge guide is installed and used in the ridger 24, the sloped land is more effective than the flat ground. This is because when the seeds are sown, the inclined guide upper surface that is lowered from the upper end of the double blade 25 to the rear side between the double blades 25 of the V-shaped rod and is lowered as the rear end rises and goes forward. The wide guide upper surface of the brazing guide member 27 can be used. Then, the seeds can be placed on the upper surface of the guide by picking the seeds from the left and right cradle 43 and placing them on the wide guide upper surface or by dropping them right above and dropping them.

  Then, the upper surface of the guide is lowered as the rear end rises and goes forward, and since the front end is narrower than the rear end, it is a trapezoidal inclined surface. It falls while being guided by the upper end side portion of 25, and falls into a small flange 28 that penetrates up and down provided on the front side. As a result, the planting groove is made straight by concentrating on driving, and even if the attention to divert the seeds to the seeding action is reduced, the seeds are dropped from the tacking port 28 and the centerline position of the groove Can be ordered in sequence. Therefore, if the sowing work can be performed properly and covered with soil, the seeds can easily keep the planting space constant and are suitable for the subsequent farm work.

  Further, when the seedling timing sound generator 46 is installed on the traveling body 7 and used, the two striking projections 47 provided on the rear wheel 18 for supporting the belt support serve as instruction means when the planting machine moves forward. Each function functions, and every time the rear wheel 18 makes one rotation, that is, every time it rotates halfway in the left direction indicated by the arrow, the rotation position is indicated by hitting. Then, the swing hammer 53 constituting the sound generating means receives a striking force at the rear end of the long handle 49 and rotates around the shaft 50 in the right direction indicated by an arrow. Then, the hammer 53 swings and the striking head 52 once separates upward from the sound source receiving member 54. However, when the striking projection 47 passes and moves downward, the hammer 53 rotates again to the left by the restoring action of the return coil spring 55, and the striking head 52 strikes the sound source receiving member 54. Therefore, if the striking head 52 and the sound source receiving member 54 are made of, for example, metal, a metal sound can be generated every time the rear wheel 18 rotates halfway. If the reverse rotation absorbing coil spring 51 is interposed in the front handle portion of the long handle 49, the reverse rotation will occur even if the rear wheel 18 rotates reversely and the striking projection 47 applies a striking force to the rear end of the long handle 49. Since the portion of the absorbing coil spring 51 is bent and the striking head 52 and the sound source receiving member 54 are kept in contact with each other, no sound is generated.

  Therefore, the operator concentrates attention on driving and looks at the front, sows the seeds from the containers on the left and right pedestals 43 only by the sense of the hand, and sows the seeds without looking at the bottom according to the sound. Just do it. Therefore, even if the attention to be directed to sowing seeds is reduced, if the sowing work can be done properly and covered with soil, it will be easy to keep the seedlings between planting stocks and suitable for the subsequent agricultural work. . When a wheel having a diameter of 16 cm is used as the belt support follower wheel 18, for example, a sound is generated every time the wheel rotates halfway, so that the distance between the stocks can be set to about 25 cm.

  During such planting travel, the main clutch lever 38 can be operated in conjunction with turning on and off of the driving force transmitted from the travel drive engine 9 of the switching guide member 66 to the transmission 10 and opening and closing of the discharge port of the fertilizer tank 21. Move to the innermost part of the long and narrow guide hole. Then, the driving force can be transmitted from the driving drive engine 9 to the transmission 10, and the cover plate of the discharge opening degree adjusting valve 23 provided in the fertilizer tank 21 is pulled against the urging force of the spring. The fertilizer can be applied to the ridge from the fertilizer tank 21 by opening a discharge hole in which the size of the hole of the adjustment plate facing the discharge port of the fertilizer tank 21 is set.

  And while planting seeds, the planting machine 1 must be turned left or right in order to continue planting when it reaches the other end of the field. Therefore, when the main clutch lever 38 is first returned to the neutral position of the switching guide member 66, the driving force transmitted from the traveling drive engine 9 to the transmission 10 is cut off and fertilization is stopped. Next, after pulling the left or right side clutch levers 40 and 41 to stop the rotation of the left or right crawler type traveling body 7, the main clutch lever 38 is moved to the innermost part of the other elongated guide hole. Then, since the planting machine 1 can be rotated to the left or right, planting can be performed in the same manner by setting the traveling direction for planting and then returning the left or right side clutch levers 40 and 41. Therefore, when the potato is planted by getting on the planting machine 1, the labor burden can be reduced and the planting efficiency is improved.

  In the above embodiment, self-propelled single-seater type seedlings have been described using the planting machine 1 for planting seeds on a flat ground or an inclined land of less than 30 degrees, but used for steep slopes of 30 degrees or more, When it advances along a contour line, the planting machine 1 becomes easy to slip off, and it becomes impossible to ensure straightness. Then, the auxiliary operation handle 61 is required. Therefore, the auxiliary operation handle 61 is installed at the rear end of the vehicle body 2 so as to be detachable. At this time, as the auxiliary operation handle 61, a tubular gripping rod 62 which is bent into a generally U-shape as shown in FIG. 6 and has a grip portion near the center and an attachment portion at both ends. Each of the end portions of the grip rod 62 has a shaft support location with a hole, and each end of the shaft support portion is inserted into the hole with an end portion as an axis and fixed with a split pin. The auxiliary levers 63 (63a, 63b) for operating both side clutch levers and the respective shaft end portions of the auxiliary levers 63 for operating both side clutch levers are respectively provided with shaft supporting portions with holes, and one ends of the respective shaft supporting portions. The rod-like connecting rod 64 is inserted into the hole with the portion as an axis, fixed with a split pin, and connected to the side clutch levers 40 and 41 with the other end as an axis to be a separable connecting point. (64a, 64b) There.

  Further, as an auxiliary operation handle mounting / removal structure of the seed planter 1, a cylinder that can be connected and separated by pulling out each end of the grip bar 62 near the left and right rear corners of the main frame 3 of the vehicle body 2. Shaped handle support portions 65 (65a, 65b) are provided, and the other end portions of both connecting rods 64 are fitted into both side clutch levers 40, 41 arranged on the left and right sides of the vehicle body 2, and can be coupled and separated by pulling out. A shaft support with a hole is provided. It should be noted that a set screw is used for coupling the handle support portions 65 corresponding to both ends of the grip bar 62, and a split pin is used for coupling the side coupling levers 40, 41 corresponding to the connecting rods 64.

  When planting seeds by the planting machine 1 equipped with such an auxiliary driving handle 61, a worker other than the rider joins and walks in the immediate rear of the planting machine 1 while gripping the auxiliary driving handle 61. The planting machine 1 is supported so as not to slip off by holding 62, and the left and right side clutch lever operating auxiliary levers 63 are appropriately operated to cooperate with the driving operation of the rider. Therefore, the planting machine 1 can be prevented from slipping off when traveling on a steep slope, and straightness can be ensured. Therefore, it is easy to keep the planting ridges constant on steep slopes, and is suitable for subsequent farm work.
