JP 2010-200699 A (Prior Art 1) Japanese Patent No. 391485 (prior art 2)

  In the case of a planting machine for bulbs such as garlic, the operator supplies the bulb to the planting device and plantes the bulb supplied with the planting device on the bush that is running. In general, four rows are planted in a ridge having a width of about 110 cm, and the interval between the rows is about 25 cm. In addition, the interval between the planting positions before and after one row is 15 cm to 17 cm, which is narrower than the width between the rows. Bulbs such as garlic have a pointed budding part that is the budding part in the future and a rooting part that is a little flat in the budding part, and the budding part and the rooting part are almost opposite to each other. Located on the side. And for the garlic bulb, the outer peripheral part between the budding part and the rooting part has almost one curved surface part and two flat parts, and the ridge line part which is an acute angle between the two flat parts. Forming. Bulbs such as garlic are planted with the rooted bottom down and the budding part up, but germinate after planting, and when the buds grow as leaves, the ridges are roughly divided into left and right as the center line and extend in an arc shape. It hangs down. At this time, when the leaves extend in the direction between the rows wider than the front and rear planting intervals, the leaves are less likely to interfere with each other, so that the growth is good. Therefore, as an ideal planting, all garlic bulbs are planted with the rooting bottom down and the budding part up and the depth from the budding part to the surface of the culm around 5-7 cm. It is desirable to plant the ridge line part in the row direction.

  Therefore, as disclosed in the prior art 1 and the prior art 2, the “holder” in the prior art 1 for loading the planted bulb and the “holding means” in the prior art 2 do not change the posture of the loaded bulb. Is to hold. However, in both cases, when a bulb is loaded, the holding member holding the outer circumference of the bulb is in a state of being elastically deformed and oriented in the pushing direction of loading. In order to pull back in the direction opposite to the loading direction, it is necessary to deform the holding member so that it can bend. In order to load the bulb, the bulb must be pushed by pinching it with at least three fingers. However, when the finger is pulled out after being pushed, a part of the holding member tends to bend, and frictional resistance acts on the finger. For this reason, if the work is continued for a long time, the operator's finger may be damaged by rubbing or the like. In addition, since the holding member must have a certain degree of strong elastic force for holding the bulb, the pushing force when loading the bulb needs to be a constant force. It becomes a burden.

  Therefore, an object of the present invention is to provide a bulb planter such as garlic that reduces the burden on the operator when the bulb is loaded.

In order to solve the above-mentioned problem, claim 1 of the present invention includes a bulb mounting plate provided with a loading portion for loading and holding an object to be planted such as a bulb or a moss, and the bulb mounting plate. In a bulb planter provided with a moving means for taking out a planting object and moving it to a planting position for planting in a field, and a planting means for taking out a planting object moved to a planting position by the moving means and planting it in a field,
The loading part of the bulb mounting plate is provided in an upper and lower through-hole portion opened in the bulb mounting plate of the horizontal flat disk, and is in a bag shape protruding in a reverse frustoconical shape downward from the through-hole portion. The cross section is a drop shape in which the openings of the semicircular arc shape and the V shape are in contact with each other, the upper part is wide, the diameter is reduced toward the lower part, and it is in the shape of an inverted truncated cone in a side view. The inverted frustoconical top surface is open, and the bottom edge is widened outward or arcuately, and a plurality of slits are formed in the vertical direction from the bottom edge and loaded. A bulb loading portion of a bulb planter such as garlic, which is formed of a flexible member so that an object can be pushed out from a lower end portion.

  In order to solve the above-mentioned problem, the present invention is characterized in that the bulb mounting plate is a thin plate-like disk, and a plurality of loading portions are provided at equal intervals on the outer peripheral side of the disk. It is a bulb | ball loading part of bulb planters, such as a garlic of Claim 1 characterized by these.

  According to the present invention, the loading portion has a bag shape protruding downward in the shape of an inverted frustoconical shape, and has a drop shape in a state in which the opening sections of the semicircular arc shape and the V shape are abutted with each other. Since the upper part is wide and the diameter is reduced toward the lower part, when a bulb such as garlic is inserted, the curved surface part of the bulb and the ridge part having an acute angle are formed in a semicircular arc shape and a V-shape in the loading part. Because the position is fixed and the direction is fixed, it is not necessary for the operator to push the bulb into the loading part, so it is possible to prevent the operator from rubbing the finger and to reduce the burden, such as bulb planting of garlic etc. Can provide a machine.

The traveling device 2 causes the crawler traveling unit 20 to travel between the ridges so as to straddle the heel MF.

  In the bulb planting apparatus 1 such as garlic, the bulb G is placed on the loading portion 31 of the bulb placement plate 3 in FIG. 8, and the push rod 50 of the bulb loading means 5 is located above the loading portion 31. The bulb holder 40 of the bulb planting holder 4 is located below the loading unit 31. When there are two workers, the bulbs G are held by holding the bulb mounting plates 3 in front of the working sheet 22 two by two, and the buds are aligned with the V-shaped portion 311 and the semicircular arc-shaped portion 310 in the loading portion 31. Insert with the tip A facing down. At this time, the rotation of the bulb mounting plate 3 is stopped.

  Next, the push rod driving unit 54 of the bulb loading means 5 is operated, the push rod driving unit 54 lowers the lifting unit 52 along the lifting rod 53, and the push rod 50 attached to the lifting unit 52 is also lowered. . Then, the push rod 50 pushes and loads the bulb G mounted on the loading unit 31 to the bulb holding unit 40 of the bulb planting holder 4 located below (FIG. 9).

  After the push rod 50 is lowered to the position where the bulb holding part 40 of the bulb planting holder 4 is loaded with the bulb G, the push rod driving unit 54 immediately raises the raising / lowering unit 52 along the raising / lowering rod 53 to return the push rod 50 to the original position. (Fig. 10). During this time, since the rotation of the bulb mounting plate 3 is stopped, the operator supplies the bulb G to the loading unit 31 during this period.

  When the push rod 50 is positioned above the loading unit 31, the circular plate-shaped body of the bulb mounting plate 3 rotates 45 degrees, and the next loading unit 31 on which the bulb G is mounted is positioned below the push rod 50. Position.

Then, since the bulb-planting holder 4 is turned upside down by 180 degrees and the bulb holding portion 40 faces downward, the tip A of the bulb G faces upward (FIG. 20).

  Further, the rotation of the horizontal rotation shaft 60 due to the extension of the cylinder rod 61b of the holder up / down reversing means 6 turns the moving frame 11 on the traveling frame 10 by rotating the rotating arm 65d of the holder front / rear moving means 65 by 180 degrees. To the front (FIGS. 11 and 12). In this operation, the distance between the hook pin 65c and the horizontal rotation shaft 60 is reduced via the link plate 65e by the rotation of the rotation arm 65d by 180 degrees, but the hook pin 65c is engaged with the engagement recess 65b of the guide plate 65a. Since the guide plate 65 a is fixed to the traveling frame 10, the longitudinally moving body 112 of the moving frame 11 slides on the horizontal guide rail 100 of the traveling frame 10, and the moving frame 11 moves forward with respect to the traveling frame 10. Move to.

  Next, as shown in FIG. 13, the multi-film upper surface abutting portion 202 made of a roller of the multi-film upper surface position detecting means 200 traces the upper surface of the multi-film so that the multi-film upper surface and the claw surface on which the crawler traveling unit 20 travels are Even if a height difference occurs, the angle of the rotating portion 203 of the moving frame 11 and the sensor arm 201 changes with respect to the upper surface of the multi-film, and the bulb planting holder vertical movement control means corresponds to the angle change. (Not shown) is operated to operate the vertical cylinder 70 of the holder vertical movement means 7 to extend the cylinder rod 70b and adjust the descending distance.

  By the operation of the vertical cylinder 70 of the holder vertical movement means 7, the lifting frame 72 is lowered, the planting holder frame 111 fixed to the lifting frame 72 is lowered, the punching device 8 is lowered and the upper surface of the multi-film, or Touch the ground. At the same time, when the planting holder frame 111 is lowered, the hook pin 65c of the holder back-and-forth moving means 65 descending together with the planting holder frame 111 is disengaged from the engaging recess 65b of the guide plate 65a fixed to the traveling frame 10. When the hook pin 65c and the engagement recess 65b are disengaged, the moving frame 11 is movable back and forth with respect to the traveling frame 10.

  In synchronism with the lowering of the elevating frame 72 by the up / down cylinder 70 of the holder up / down moving means 7, the hole punching device 8 operates to open a hole for bulb planting in the multi-film covering the bulb planting basket M. Each punching portion 87 of the punching device 8 pierces the four bar-shaped claws 80 to the center of the planned planting position, and then tears the upper surface of the multi-film while moving from the center to the peripheral direction.

  Next, the pushing cylinder 91 of the bulb planting means 9 is actuated, and the pushing shaft 90 is lowered from the base portion toward the tip portion of the outer peripheral holding portion 41 of the bulb planting holder 4. The push-out shaft 90 pushes the bulb G loaded in the bulb holding part 40 of the bulb planting holder 4 from the bulb holding part 40 and the outer circumference holding part 41 and pushes it into the soil at the planting position to plant it at a certain depth (see FIG. 14).

  During the time when the pushing shaft 90 of the bulb planting means 9 is lowered and raised, the traveling frame 10 moves forward at the traveling speed of the traveling device 2, but the planting holder frame 111 of the moving frame 11 is formed by the punching device 8. Is stopped at that location due to the ground friction of the traveling frame 10 and moves relatively rearward along the horizontal guide rail 100 of the traveling frame 10.

  The extrusion shaft 90 descends to a certain depth, and after the bulb G is planted in the soil, ascends and exits the soil (FIG. 15), the holder upside down means 6 is actuated again, and the bulb planting holder 4 is The bulb holding portion 40 is turned upside down by 180 degrees and the holder holding / moving means 65 is activated at the same time, and the hook pin 65c is moved forward by the rotation of the turning arm 65d of the holder moving / forwarding means 65 by 180 degrees. At the same time, the vertical cylinder rod 70b of the holder vertical movement means 7 is shortened, the lifting frame 72 is raised, and the hook pin 65c is raised along the hook pin contact guide 65f to be engaged with the engagement recess 65b. As a result, the moving frame 11 is linked to the traveling frame 10 in the front-rear direction (FIG. 16).

This state is the same as FIG. 8, and this operation is taken as one planting cycle, and garlic is planted sequentially as the traveling device 2 travels.

  The present invention is highly applicable to bulb planters such as garlic used for planting bulbs such as garlic.
