摘要： PROBLEM TO BE SOLVED: To permit the fertilization pump to be mounted to the mobile machine body in the sulky type rice transplanter equipped with a plurality of paste fertilization umps in order to reduce cost from the view point of the operation mechanism in the fertilization pumps. SOLUTION: A plurality of fertilization pumps 23 are attached to the rear part of the mobile machine body in rows in the horizontal direction. A part of fertilization pumps 23 among the whole fertilization pumps are directly connected through the common fertilizer-introducing tubes 43 and they are allowed to communicate to each other. The cylinders 43 for introducing the fertilizer in one group of the fertilizer pumps are connected through the communicating tube 50 to the other pump group 23.

摘要： PROBLEM TO BE SOLVED: To rationalize a fertilizer-sending mechanism by cutting costs, by making it easy to handle or the like without impairing its compactness. SOLUTION: Three shutters 26 made of a leaf spring are installed in row so as to be shiftable between an open attitude where a supply channel w guiding fertilizer from a hopper 13 to a feeding roll R is made to be opened and a closed one where the channel w is made to be cut off. The shutters 26 become flat and cut off the supply channel w in an open attitude, and the shutters 26 are folded along the inside wall of the hopper 13 and take a step backward from the channel w in a closed attitude. The shutters 26 are held in a roll case 18 in either attitude.

摘要： PROBLEM TO BE SOLVED: To join plural discharge pipe lines to a single end pipe line while preventing the bad flow of granule in the discharge pipe lines by a gradual inclination. SOLUTION: This feeder comprises plural sending out mechanisms 19 loaded side by side at the rear of a driver's seat. The feeder can be changed from an action state for supplying a fertilizer transported from the sending out mechanism 19 to a feed pipe line 21 communicating with a furrow opener to a discharge state for transporting the fertilizer to a discharge pipe line 48 connected to the lower part of the sending out mechanism 19. The plural discharge pipe lines 48 attached to each sending out mechanism 19 is collected and joined to a single end pipe line 49 installed below the sending out mechanism 19. The end pipe line 49 is linearly connected to a first discharge pipe line 48A of the sending out mechanism 19 located at the most separated position from the end pipe line in the right and left direction and the two remaining discharge pipe lines 48B and 48C are connected to the first discharge pipe lines 48A, respectively.

摘要： PROBLEM TO BE SOLVED: To improve a fitting operation of a sending out mechanism to a machine body so as to carry out the operation readily and simply, by contriving the supporting structure of the sending out mechanism. SOLUTION: This feeder is equipped with a hopper 18 for storing a fertilizer, a sending out mechanism 19 for transporting the fertilizer of the hopper 18 and a supply hose 21 for feeding the transported fertilizer to a furrow opener attached to a planting part. The sending out mechanism 19 is loaded on a machine body frame F immediately behind a driver's seat 67 through a stay 29 supporting the sending out mechanism. The lower part of the stay 29 is bent forward and the position of a fitting part 86 of the stay 29 to the machine body frame F is made approximately coincident with the position of the center of gravity of the sending out mechanism 19 in the longitudinally direction in a side view.

摘要： PROBLEM TO BE SOLVED: To simplify a rotation preventing structure for a sending out shaft for controlling the amount of granule sent out and to reduce its cost in adopting a middle fertilizing apparatus having a driving system equipped with a one-way clutch. SOLUTION: This feeder is equipped with an amount adjusting mechanism D capable of changeably setting a fertilizer supply width of a recessed part 24 formed between a stationary roll 25a and a movable roll 25b by the rotation of a rotation adjusting tool 70. A passive arm linked through a one-way clutch to a sending out shaft 23 is linked and connected by a connecting rod to a rotary arm to be driven and rotated. A driving mechanism for revolving a sending out roll 25 in a fixed direction by the reciprocating rocking movement of the passive arm is constituted. The sending out shaft 23 is provided in an integrally rotating state with a circular grip 81 to be engaged with the sending out shaft 23 in a state of stopped rotation by manual operation.

摘要： PURPOSE: To eliminate the stoppage of divided crop seedlings at positions on the fronts of resistant guides because the seedlings can not pass between the resistant guides, and the trouble of a good operation for packing the seedlings into a box due to the passage resistance of the resistant guides in spite of the packing operation of a longitudinally moving seedling- pressing tool. CONSTITUTION: This machine for dividing the seedlings of a crop is provided with a seedling- dividing section B for discharging the seedlings divided in an inclined posture in which the positions of the roots of the divided seedlings are lower than those of their stem tips, and with a packing section having a packing mechanism for press-packing the divided seedlings dropped from a divided seedling-discharging opening 7 into seedling boxes with a seedling press tool. Further, a resistant mechanism A for acting on the stem tips of the inclined divided seedlings discharged from the divided seedling-discharging opening 7 to change the posture of the seedlings into a standing posture suitable for the packing operation, and a back flow- preventing mechanism E are disposed. The resistant mechanism A comprises resistant guides 11 capable of changing the posture of the seedlings into a receiving posture enabling to receive the divided seedlings and into a discharge posture allowing the passage of the divided seedlings, and springs 11a for energizing the return of the resistant guides to the receiving posture. The back flow-preventing mechanism E is disposed behind the resistant mechanism A, comprises resistant guides 56 and springs for closing the opened resistant guides 56, and has the same structure as the resistant mechanism A.

摘要： PURPOSE: To provide a structure for a vertical seedling feed part capable of simplifying the evacuating operation of seedling pushing rods in supplying seedlings and a moving mechanism thereof and easily performing the seedling supply operation in spite of the obtained sure vertical feed operation by forcedly pushing the seedlings with two upper and lower seedling pushing rods. CONSTITUTION: This structure for a vertical seedling feed part is obtained by installing upper and lower seedling pushing rods 13 and 14 capable of acting on the stem tip and root part of each seedling on a seedling-carrying platform 5 and providing an interlocking means for synchronizing and interlocking the upper and lower seedling pushing rods 13 and 14 with a vertical feed mechanism 9 so as to forcedly push the seedlings with the upper and lower seedling pushing rods 13 and 14, following the driving with a vertical feed mechanism 9, and constituting the upper and lower seedling pushing rods 13 and 14 so as to enable the positional change from an operating position for bringing the upper seedling pushing rod 13 into contact with the stem tip of the seedling and an evacuating position for moving the upper seedling pushing rod 13 upward from the operating position and permitting the passage of a seedling feed box containing the seedlings housed therein, in a rush transplanter constituted by sliding and charging a seedling feed box 4 in each row seedling carrying part of a seedling-carrying platform 5, and then pulling the seedling-carrying platform 5 to the rear so as to supply only the seedlings.

摘要： PURPOSE:To prevent seedlings discharged through a seedling discharge opening from spreading in the left and right direction before planting in a rice transplanter equipped with a planting tine having left and right seedling nipping parts at the top part so that they may be driven to rotate in a state in which it is passing through the seedling discharge opening of a sliding plate. CONSTITUTION:Left and right members 12 for preventing spreading of nipped seedlings, capable of preventing the top part side of seedlings nipped by left and right seedling nipping units 8a from spreading in the left and right direction are attached to a planting tine in a state in which they are projected on the rearward side of the descent-rotation direction of the planting tine so as to prevent the seedlings from spreading on the forward side of the position where they are nipped by the seedling nipping units 8a and in which they can pass through outside a sliding plate.
