Description

TECHNICAL FIELD The present invention relates to a seedling planting machine.

[Problems to be Solved by the Invention]

In the form where the seedling tank that supplies seedlings to a plurality of seedling planting devices is moved far and near to change and adjust the separation of seedlings and the number of planted plants,
Since the seedling tanks are long on the left and right for a number of planting lines, it is very difficult to move them in parallel.

[Means for solving problems]

In order to solve the above problems, the present invention provides a seedling tank 3
A seedling guide frame 5 that guides the lateral movement of the seedling guide frame 5 is movably provided on the machine frame 1, and guide frame protection members 6 that protect the side edges of the seedling guide frame 5 are provided on both the left and right sides of the machine frame 1. A horizontal axis provided on the bracket 2 provided on the left and right sides and installed between the left and right brackets 2
An adjusting mechanism 8 for moving and adjusting the seedling guide frame 5 by rotating 17 is provided near the seedling guide frame 5, and both ends of the horizontal shaft 17 are pivotally supported by the mounting portions 7 of the left and right guide frame protecting members 6. It is a seedling planting machine.

[Advantageous effects of the invention]

In the seedling planting operation, the seedling planting device acts on the seedling take-out port formed in the seedling guide frame 5 to separate one seedling supplied from the seedling tank 3 into a field. The seedling tank 3 reciprocates in the left-right lateral direction along the seedling guide frame 5 to operate the seedlings and continue seedling planting, and the guide frame protection member 6 is provided on the left and right end portions of the seedling guide frame 5. Positioned to protect the end of the seedling guide frame 5 from contact with other obstacles. Also,
When changing the seedling separation or the number of plantings in the seedling planting, the adjusting mechanism 8 moves and adjusts the seedling guide frame 5,
The horizontal axis 17 is rotated around the mounting portion 7 of the guide frame protection member 6 to move the seedling guide frame 5 so that the working position of the seedling planting device can be changed to the perspective. The operation position of the seedling planting device with respect to the seedling guide frame 5 is deepened to increase the number of seedling divisions, and conversely the distance is reduced to decrease the seedling guide frame 5, and the seedling guide frame 5 is moved in parallel to perform accurate seedling planting. The number of lines can be changed and adjusted, and since the guide frame protection member 6 and the horizontal shaft 17 of the adjustment mechanism 8 are supported by the same bracket 2, the configuration can be simplified and the assembly and division can be simplified.

〔Example〕

 An embodiment of the present invention will be described below with reference to the drawings.

Reference numeral 12 denotes a steering handlebar attached to the rear end of the traveling body. A machine frame 1 made of a pipe is provided in the lower portion of the handlebar 12 in the lateral direction, and flat ∩-shaped brackets 2 are fixed to both left and right ends of the handlebar. A sliding body 13 is provided on the upper side surface so as to be movable back and forth, and the seedling guide frame 5 is integrally provided over the sliding bodies 13, 13. The seedling guide frame 5 is formed into an L-shape on the side surface, and the seedling inlet 14 is provided at each elevating operation locus A of the seedling planting device that is arranged at a fixed position with respect to the machine body. The part 4 may be provided so as to be slidably guided left and right, and the seedling tank 3 may be configured to move in the front-rear direction and the up-down direction integrally with the seedling guide frame 5.

The bracket 2 is provided with an axial hole 15 and the outer end is provided with a seedling guide frame 5.
Frame protection member 6 formed to be bent so as to be located outside the tip of the
The mounting portion 7 can be fitted into the shaft hole 15 from the outside, and the arm 16 provided in the mounting portion 7 can be fixed to the outer surface of the bracket 2 and integrally mounted. The adjusting mechanism 8 is provided with a horizontal shaft 17 into which the shaft portions 9 at both ends are fitted in the mounting portion 7, and an engagement provided in parallel with the shaft portion 9 at both end portions of the horizontal shaft 17 at a constant interval. A shaft 18, an engaging groove 19 with which the engaging shaft 18 engages in the sliding body 13, and an adjusting lever 20 and the like protruding from an intermediate portion of the lateral shaft 17, and the rotating lever 20 is operated. Thus, the sliding body 13 can be slid back and forth via the engagement shaft 18, and the seedling guide frame 5 can be moved and adjusted back and forth. Reference numeral 21 is a lever guide that can engage the adjustment position of the adjustment lever 20.

The float 10 has its rear end pivotally supported so as to rotate up and down with respect to the machine body, and its front end is connected to the attachment portion 7 of the guide frame protection member 6 by a pivotal support member 11. The hole is located inside the bracket 2, and the mounting portion 7 is fitted into the shaft portion 9 from the shaft hole 15 of the bracket 2 through the shaft hole of the pivotally supporting member 11. A long hole 23 is provided in the pivot member 11 and a pivot pin 24 of the float 10 is fitted therein, and the float 10 is connected so as to move up and down. Each seedling planting device moves up and down on the track a in conjunction with the seedling planting, the seedling tank 3 is reciprocally moved in the left-right direction along the seedling guide frame 5, and the seedling separating action of each seedling 14 is performed. Done. When the seedling tank 3 moves to the left end or the right end of the seedling guide frame 5, the seedlings in the seedling tank 3 are fed forward at regular intervals, so that the seedling separation apparatus continuously carries out the seedling separation. Since the left and right ends of the seedling guide frame 5 are provided in fixed positions over the reciprocating movement width of the seedling tank 3, the side end opposite to the moving side of the seedling tank 3 is closer to the seedling tank 3 side end. Although the guide frame 5 may largely project, since the guide frame protection member 6 is provided at a fixed position on the outer end of the guide frame 5, the guide frame 5 does not directly contact the ridge or the like. float
Although 10 slides up and down in response to the ground contact pressure on the soil surface, the pivot member 11 rotates about the shaft portion 7 to maintain the vertical swing smoothly.

To change the number of separated seedlings to be planted, move the seedling guide frame 5 in the front-rear direction. To increase the number of seedlings, move the seedling guide frame 5 forward to bring it closer to the seedling planting device side. In addition, when reducing the number of seedlings, it may be retracted. These operations are performed by turning the adjusting lever 20 up and down. When the horizontal shaft 17 is rotated, the left and right sliding bodies 13, 13 are moved and adjusted in parallel in the front-rear direction by the engagement shaft 18, whereby the seedling guide frame 5 is moved forward and backward, and the seedling tank 3 is also moved.

If the guide frame protection member 6 is pulled out from the bracket 2 to the outside, the pivotal support member 11, the horizontal shaft 17, etc. can be disassembled.
