Description

  The present invention relates to a bulb planting machine for planting bulbs such as garlic at a predetermined position of a field basket.

  As shown in FIGS. 7 to 8, bulbs such as garlic have a pointed budding part A which is a future germination part and a rooting part B which is a root part and is slightly flat. The budding part A and the rooting bottom part B are located almost on opposite sides. And for the garlic bulb, the outer peripheral part between the budding part A and the rooting part B has almost one curved part C and two flat parts D, and an acute angle is formed between the two flat parts D and D. The ridge line part E which is an angle is formed.

  Bulbs such as garlic are planted with the rooted bottom B facing down and the budding part A facing up, but germinate after planting, and when the bud grows as a leaf F, the ridgeline E becomes the center line and is roughly left and right. It is divided into arcs and extends and hangs down. (See FIG. 9. Note that FIG. 9 is an explanatory diagram. Actually, when the leaf begins to grow, the original bulb disappears small, and a new bulb not shown is growing.)

  Therefore, as an ideal planting, all the garlic bulbs should be 5-7 cm deep from the budding part A to the bud surface with the rooting part B facing down and the budding part A up. It is desirable to plant the ridgeline portion E in the direction of the row.

Known bulb planters for garlic and the like are disclosed in Japanese Patent Application Laid-Open Publication No. 2007-175209 (Prior Art 1) “The planting holder in which crops are stored in the planting holder at the storage position and conveyed by the circulation mechanism”. When the plant is in the planting position, the crop is pushed by the push rod lowered by the vertical movement mechanism and is pushed out from the lower end portion of the planting holder to be planted on the ground. " .

  If all the bulbs such as garlic are planted manually, it can be planted in an ideal orientation and depth, but it requires a lot of human labor and long hours of work, which is very burdensome for the operator. Growing up, it was difficult to plant large areas. For this reason, the planting machine like the prior art 1 is disclosed.

  However, bulbs such as garlic are planted with a root from bottom B and budding part A facing up to a depth of 5 to 7 cm from budding part A to the ridge surface, and ridge line E is In order to plant in the direction of the row, it is necessary to securely fix and hold bulbs such as garlic in each mechanism, and to regulate the posture of the bulbs until planting in the soil.

  For this reason, when planting a bulb in the soil, it is necessary to push the bulb into the soil while keeping the posture of the bulb as small as possible. Although there is no disclosure in the prior art 1 of details when pushing into the soil, “when the planting holder 2 is in the planting position (G), the crops are lowered onto the extrusion rod 4 that is lowered by the vertical movement mechanism 5. It is pushed, pushed out from the lower end 22 of the planting holder 2 and planted on the ground. " To push the bulb into the soil and plant it in this way, the extrusion rod 4 in the case of the prior art 1 for guiding the bulb into the soil is necessary. However, the extrusion ridge and the planting holder are provided separately, and when pushing into the soil, the extrusion ridge needs to be accurately put in and out of the center of the planting holder. For this reason, it is necessary to improve the circulation accuracy of the wire 31 holding the planting holder which is a circulation mechanism, or to loosen the accuracy of the fitting portion between the planting holder and the extrusion rod. In this case, it is not suitable for reducing the manufacturing cost, there is a problem in maintenance adjustment in use, and it is not possible to accurately hold the posture of the bulb held in the planting holder and push it to the planting position in the soil. There is a problem that is stable.

Run.

The power to the bulb planting device 1 is transferred from the transmission output sprocket 243 of the transmission 24 to the planting device input sprocket 25 fixed to one end of an idler shaft rotatably provided in the frame 100 in the horizontal direction orthogonal to the traveling direction. The idler sprocket 26 transmitted by the chain and fixed to the other end of the idler shaft is rotated. The idler sprocket 26 is connected to a driving sprocket 34 of the orbiting movement mechanism 3 of the bulb planting apparatus 1 and coaxially fixed and rotated by a roller chain to transmit power, and the orbital movement mechanism 3 of the bulb implantation apparatus 1. The roller chain 31 is driven by a drive sprocket 34.

  The engine output pulley 231 drives the transmission input pulley 241, and also drives the hydraulic unit 29 connected to the transmission pulley 241. The hydraulic unit 29 is driven to generate hydraulic pressure, and the pushing device 5. The cylinder 51 is operated. The cylinder 51 may be operated electrically without using hydraulic pressure.

  Next, the operation | movement at the time of the planting operation | work of the bulb planting apparatuses 1, such as a garlic with which the traveling apparatus 2 which is embodiment of this invention was equipped is demonstrated.

  The operator S sits on the operator seat 22 provided at the rear of the machine body and steers the bulb of the bulb planting holder 4 provided on the roller chain 31 that circulates between the loading position X and the planting position Y of the circling movement mechanism 3. The budding part A is brought into contact with the bulb holding part 40 in the outer circumference holding part 41 to be held, and the bulb is loaded.

  The loaded bulb G moves around from the loading position X to the front side of the operator S together with the bulb planting holder 4 and moves to the planting position Y. When the roller chain 31 to which the bulb planting holder 4 is attached circulates, the bulb planting holder 4 is oriented in the downward direction in which the bulb loading direction is directed to the operator at the loading position X and the bulb is pushed out at the planting position Y. Turn to automatically.

  When the bulb planting holder 4 circulates and reaches the planting position Y, the end bearing 63 of the holder slide shaft 61 of the slide mechanism 6 comes into contact with and is guided by the guide rail 71 which is the guide portion 7 provided on the frame at the planting position Y. The holder slide shaft 61 slides to the planting basket M side, and the bulb planting holder 4 attached thereto slides similarly. Thereby, the open | release side edge part of the outer periphery holding | maintenance part 41 of the bulb planting holder 4 contact | abuts to the heel surface.

  Subsequently, a sensor (not shown) senses the bulb planting holder 4 that has reached the pushing position, and the cylinder rod 512 of the cylinder 51 of the pushing device 5 extends to lower the pushing frame 52, and the bulb planting holder 4 is pushed out. The shaft 42 is pushed out to the heel M side. Thereby, the bulb G is pushed out from the outer circumference holding portion 41 into the ground of the ridge M by the bulb holding portion 40 provided at the tip of the pushing shaft 42 and planted. At this time, since the open side end of the outer periphery holding portion 41 of the bulb planting holder 4 is in contact with the heel surface, the bottom B of the bulb G is brought into contact with the planting ridge upper surface MF before the posture changes when the bulb G is pushed out. Abutted and held by the soil above and below the bulb holding portion 40 on the push-out side, it is pushed out to the desired planting soil position without changing its posture.

  When the planting position at the specified depth is reached, the cylinder rod 512 of the cylinder 51 contracts and the pushing frame 52 rises. As a result, the pushing shaft 42 of the bulb planting holder 4 is raised by the urging force of the compression spring 422.

  With the rotation, the bearing 63 of the holder slide shaft 61 of the slide mechanism 6 is disengaged from the guide rail 71, and the holder slide shaft 61 slides upward by the urging force of the slide spring 62 to separate the bulb implantation holder 4 from the heel surface MF. Raise to position. In the raised state, the bulb planting holder 4 revolves around the loading position X, and the bulb is loaded by the operator S. By repeating this cycle with each of the plurality of bulb planting holders 4 attached to the roller chain 31 of the orbital movement mechanism 3, bulb planting operations are continuously performed. Further, since the rotational speed of the roller chain 31 of the circular movement mechanism 3 is synchronized with the transmission 24 so as to be the same as the traveling speed of the traveling device 2, the bulb implantation holder 4 is in contact with the upper surface MF. Is stopped with respect to the ridge surface MF, and even when the bulb G is pushed out into the soil of the pod, the bulb G is reliably pushed out in the vertical direction, so that the planting posture of the bulb G is hardly changed and the planting posture is stabilized.

  The present invention is highly applicable as a planting device for planting bulbs such as garlic.
