Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of a seedling plant. 2. Description of the Related Art Conventionally, seedlings on a seedling mounting table which are moved left and right to supply seedlings to a seedling mounting apparatus are seeded on the seedling mounting table. And a plurality of floats for sloping the soil surface below the seedling transport device and arranging the seedling placement position in the field at intervals from one side to the other. There is a seedling planter for row planting. In this seedling transplanter, the float is arranged near the lower part of the seedling transfer device, so that the float interferes with the drive mechanism for the seedling transfer device or the float acts on the transmission mechanism of the seedling transfer device. In order to prevent interference, the position of the seedling mounting table is limited, and there is a possibility that the compactness of the body is hindered and the weight balance of the body is deteriorated. [0003] In the present invention, the drive mechanism for the seedling transfer device is arranged so as not to be restricted by the float, and the body is made compact. According to the present invention, the seedlings on the seedling table 17 are planted at the left and right moving ends of the seedling table 17 which moves left and right to supply the seedlings to the seedling planting apparatus 18. A seedling transporting device 36 for feeding to the attaching device 18 side is provided, and a plurality of floats 25 for sloping the soil surface below the seedling transporting device 36 to level the seedlings in the field are spaced apart from each other on the left and right sides. In a plurality of seedling planters arranged individually, the seedling placement positions of the adjacent seedling planting devices 18 in the rear view of the machine are arranged with different floats 25 so as to be leveled between the adjacent seedling planting devices 18. A seedling transplanter is characterized in that drive mechanisms 37 and 38 for the seedling transfer device 36 are arranged. [0005] This seedling planter has a drive mechanism 37, 38 provided between adjacent seedling planters 18 in rear view of the machine.
Thus, the seedling transfer device 36 is driven to send the seedlings on the seedling mounting table 17 to the seedling planting device 18 side. A space between the floats 25 is located between the adjacent seedling planting devices 18 in the rear view of the machine body. Therefore, the driving mechanism 3 for the seedling transfer device 36
The seedlings 7 and 38 can be stored in a position where they do not easily interfere with the float 25 between the adjacent seedling planting devices 18 where the space between the floats 25 is located.
Not only can the interference with the seeds 38 be suppressed, but also the positional relationship between the float 25 and the drive mechanisms 37 and 38 increases the degree of freedom in the arrangement of the seedling mounting table 17, thereby reducing the size of the body and improving the weight balance. Can be planned. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A tractor body 8 has a front wheel 3 and a rear wheel 10 that can be steered by a steering handle 9 and is driven by an engine E below a cockpit 11 in a four-wheel drive travel. It is a form. A control floor 13 is provided from the left and right sides of the steering post 5 at the front of the vehicle body 8 to the left and right sides of the cockpit 11 at the rear, so that the driver can easily move. 27a is a rear wheel rolling shaft, 10a is
Left and right rear cases 1 from which the axles of the rear wheels 10, 10 protrude.
This is a rear wheel frame that connects 0b and 10b sideways. The rear wheels 10, 10 can be rolled around the rear wheel rolling shaft 27a with respect to the body. The seedling plant 12 is connected to the rear of the vehicle body 8 by a parallel link mechanism 14 so as to be movable up and down. The parallel link mechanism 14 is turned up and down with respect to the vehicle body 8 by the expansion and contraction of a lift cylinder 15 by hydraulic pressure. As a result, the elevation is controlled. Further, the seedling planting device 12
A float 25 that slides on the soil surface, a mat-type seedling table 17 that accommodates mat-shaped seedlings, and reciprocates to the right and left at a certain interval and feeds the seedlings by feeding it vertically to the lower rear end of the slope. Seedling plant 18 for separating and transplanting the seedlings supplied from 17
It is configured as a multi-row planting form. Between the cockpit 11 of the vehicle body 8 and the seedling mounting table 17, there is provided a fertilizer device 19 for applying fertilizer to the seedling planting soil surface. The fertilizer application device 19 includes a fertilizer application hopper 20 along the moving width direction of the seedling mounting table 17, a feeding device 21 for feeding the fertilizer stored in the fertilizer hopper 20, and a guide for the fed fertilizer to the pipe 22 by blowing air. The fertilizer application port 24 at the tip of the pipe 22 is opened so that fertilizer can be applied to the soil near the seedling planting position behind the flat part of each float 25. The vehicle body 8 includes a front transmission case 26 at the center of the front axle housing 1,
The rear transmission case at the center of the rear axle housing is connected to the rear transmission case by a vertical frame 27, and the front wheels 3 and the rear wheels 10 and the like are brought into a fixed relationship through the transmission mechanism inside the transmission case and the vertical frame 27. Can be transmitted. At the left and right ends of the front axle housing 1, a final case 2 having an appropriate height is integrally formed downward. The lower end of the final case 2 is steerable about a vertical kink pin axis. And a front wheel 3 mounted on a front axle 29 outside the steering case 28 can be steered. An auxiliary seedling support frame 7 projecting from the upper side of the front wheel 3 in the form of a crank from the upper side of the front wheel 3 and having a support portion 30 on the outside of the floor 13 next to the steering post 5 is bolted to the upper side of the left and right final cases 2. Install with a fastening tool such as a nut. The left and right support portions 30 support a seedling receiving support portion 31 having a multi-stage auxiliary seedling 6 on which mat-shaped seedlings are placed.
The upper part of the steering post 5 is connected by a connecting rod part 32 formed in a loop shape so as to straddle the left and right sides. A pipe 33 at the center of the auxiliary seedling receiver 6 disposed at a constant interval around the outer periphery of the seedling receiving support 31 is pivotably fitted to each other, and a plurality of seedlings each having a rectangular shape in a plan view are provided. Can be turned or fixed by operating the lever 34 at the lower part, and the auxiliary seedling receiver 6 can be turned in a direction that facilitates the placement of seedlings on the auxiliary seedling receiver 6 and the removal of seedlings. Reference numeral 35 denotes a rack plate on which a rack with which the lever 34 can be engaged is formed. The auxiliary seedling support frame 7 having such a structure is disassembled by the bracket 4 having the support portion 30, the pipe portion 33 of the auxiliary seedling support 6, the seedling receiving support portion 31 integrated with the connecting rod portion 32, and the like. It is a structure that can be assembled freely. Although the bracket 4 in FIGS. 1 and 2 is formed by integrally welding a square bar into a crank shape, in FIG. 3, a part of the bracket 4 is formed by bending a thick sheet metal member into an L-shape. Is what you do. Further, the brackets 4 and the auxiliary seedling supporting frames 7 may be integrally connected to form a rigid structure together with the final case 2 and the like. When the amount of seedlings on the seedling table 17 becomes small during the seedling operation, the seedlings are temporarily stopped there and the pilot takes out the seedlings on the auxiliary seedling receiver 6 one by one, and the rear seedlings. It is supplied to the mounting table 17. Since the weight of the seedling placed on the auxiliary seedling receiver 6 is supported by the final case 2 of the front axle housing 1 via the auxiliary seedling support frame 7 and the bracket 4, the weight of the seedling is directly supported by the front wheels 3. In addition, since these left and right upper end portions are connected in a loop, even if the auxiliary seedling receiver 6 receiving the heavy seedling is supported in a posture protruding outward from above the front wheel 3. It provides stable support and does not give excessive force to the bracket 4 and the mounting portion to the final case 2. As shown in FIGS. 4 and 5, the fertilizing port 24 of the fertilizing pipe 22 is set closer to the float 25 of the planting streak by each planting device 18, and the seedling mounting The drive arm 38 for driving the vertical feed arm 37 of the seedling vertical feed device 36 of the table 17 is provided opposite to the seedling planting portion where the fertilizer application port 24 is not located, so that the fertilizer application port 24, the fertilizer application pipe 22 and the like are provided. Easy installation. In the multi-row type float 25, the float front portion 41 is formed wider and the float rear portion is formed narrower in order to level the soil surface of the seedling placement position of each seedling planting device 18. The rear portion 39 is located between the left and right adjacent seedling planting devices 18. In addition, since a plurality of floats 25 are provided, the space between the floats 25 is a space between the seedlings where the float rear portion 39 is not located. A fertilizing port 24 for guiding fertilization while cutting a fertilizing groove in the soil surface by looking at the tip of each fertilizing pipe 22.
Is attached to each seedling planting device 18 side of the float rear portion 39 of each float 25, and fertilizes at a position close to the planting streak of the seedling A. At this time, in the case of a float configuration in which the float rear portion 39 is located on both left and right sides of the seedling planting device 18, the fertilizer is applied to only one side. With respect to the installation position of the fertilizer application port 24, the drive arm 38 for vertically transporting the seedlings faces the seedling A planting section between the seedling machine 16 where the fertilization application port 24 is not located. Provided. In the illustrated example, the seedling transplanter is an eight-row seedling type, but the seedling mounting table 17 has a seedling vertical feeding device 36 and a vertical feeding arm 37 that are driven every four left and right rows, and is integrated with the seedling mounting table 17. It is reciprocated over a fixed width on the left and right. During this movement, the seedling vertical feeding device 36 is stopped and does not perform vertical feeding of the seedlings. However, when reaching the left and right lateral ends, the vertical feeding arm 37 of the seedling vertical feeding device 36 rotates at a fixed position. Is driven longitudinally to feed the seedlings to the seedling planting apparatus 18 at regular intervals. The drive arm 38 is driven and rotated at a fixed position in the seedling transplanter body 16 and is provided at a space between the left and right adjacent floats 25. Since the fertilizer application port 24 is located on the rear side of the float 39 of the seedling planting device 18 between the left and right adjacent floats 25, the distance between the upper surface of the float 25 and the lower side of the seedling table 17 is high. Because it is open, it is hard to hinder the installation and rotation of the drive arm 38 and the arm shaft 40, etc.
Therefore, the installation of the fertilization opening 24 is also easy. 6 is different from the above example in that the side floats 42 on both left and right ends of the float 25 of the multi-row (eight-row) form are narrowed to about the float rear portion 39 of the center float 43. Thus, the float front end portion 44 is formed at an acute angle to reduce the laterally outward pushing action. Reference numeral 45 denotes a leveling portion for leveling the seedling planting portion, which is formed to protrude laterally and is formed lower than the height of the center portion of the float.
