Description

  The present invention relates to a bulb planting machine for planting a bulb such as garlic at a predetermined position of a field basket. Although it relates to a garlic planting machine in detail, it can be applied as a planting machine for bulbs having a similar shape other than garlic.

  The garlic planting is generally planted in four rows on a cocoon having a width of about 110 cm as shown in FIG. 10 as a cross-sectional explanatory view of the cocoon, so the interval between the rows L is about 25 cm. Further, as shown in FIG. 11 as a plan view of the ridge M, the spacing between the planting positions N before and after one row L is 15 cm to 17 cm, which is narrower than the width between the rows. In general, these planting positions N are determined by the holes in the multifilm.

The bulbs G 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 as shown in FIGS. The budding part A and the rooting bottom part B are located on substantially opposite sides of each other. And for the garlic bulb, the outer peripheral part between the budding part A and the rooting part B has almost one curved surface part C and two flat parts D, and between the two flat parts D, D A ridge line portion E which is an acute corner portion is formed.
Bulbs such as garlic are planted with the root B being the bottom and the budding part A being the top, but germinating after planting, and when the bud grows as a leaf F, the ridgeline E is the center line and is roughly left and right. (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 in depth 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 ridge line portion E in the row direction.

  As a garlic bulb planting machine, Japanese Patent No. 2553427 (Prior Art 1) states that “a frame is provided with a wheel and is self-propelled by an engine or pulled by a tractor, and is rotatably supported by the frame and rotated by the rotational force of the wheel. A drum driven in a rotational direction; a vacuum pump for supplying negative pressure into the drum; a pipe projecting from the drum and communicating with the interior of the drum; and communicating with the pipe and substantially straight with respect to the pipe And a garlic bulb adsorbing opening opened at the tip of the garlic bulb adsorbed by the elastic force of the spring and urged to be substantially perpendicular to the pipe by the elasticity of the spring. A bulb holding pipe in which the suction port passes through the soil at a predetermined depth as the drum rotates, and the bulb holding pipe as the drum rotates. A garlic bulb planter comprising: a ventilation shutter mechanism that shuts off the communication between the bulb holding pipe and the inside of the drum and releases the suction force of the bulb suction port when substantially aligned with the pipe. Is disclosed.

  Japanese Patent Application Laid-Open No. 2004-187571 (Prior Art 2) discloses as a bulb planting device “a holding means (holder) for holding an object to be planted such as a bulb or a moss, and an object to be planted from the holding means.

  When all the bulbs such as garlic are planted manually, it can be planted in the ideal orientation and depth, but it places a heavy burden on the operator's waist and is particularly difficult to harvest garlic. In the case of a farm with a large planting area where multiple rows, usually four rows, are planted on a single vine for the purpose of a large number of people, a lot of manpower and long hours of work are required, and the burden on the worker becomes very large. Was difficult.

  Further, in the case of the prior art 1, a large-scale configuration such as “a vacuum pump that supplies negative pressure into the drum” or “a pipe that protrudes from the drum and communicates with the inside of the drum” makes it possible to perform actual work. In addition, there is a problem that it is difficult to stably operate the apparatus and that it is difficult and difficult to maintain due to a complicated configuration. In particular, since the bulb is held by air suction, the shape of the bulb is not constant, so that there is a drawback that the bulb holding tends to become unstable due to air leakage. In the prior art 2, the bulb holding part and the pushing part are separate, and the budding part (sprouting part) is surely positioned at the engaging part of the pushing part. Assembling accuracy and parts accuracy of each mechanism are required, and there is a problem that manufacturing cost increases. Furthermore, the prior art 2 has a drawback that if it is loaded while being tilted when it is loaded with a bulb, it will be held in a tilted state, and will be planted in a tilted posture even when it is pressed against the plant. There was a problem.

  Moreover, in the prior art 3, since the structure of the planting holding | maintenance part is complicated and the pushing part shape is flat, the attitude | position of the bulb | ball at the time of pushing was unstable, and there existed a possibility of falling in soil and falling down. In addition, there is a problem that the holding portion needs to be adjusted when the size of the bulb changes. Furthermore, the planting holders of the planting machines disclosed in the prior arts 1 to 3 have a drawback that it is uncertain that the garlic and other bulbs are planted in an up-down direction and a left-right direction. It was. In particular, it grows in the left-right width direction of the row L with the apex head, which is the budding part A, facing the root B, and the leaves F being widely spaced from the adjacent bulbs G. Thus, no mechanism or device has been known that can plant bulbs G such as garlic at a certain depth in each planting hole N with the ridge line E directed in the row direction.

In order to solve the above problems, the present invention is a planting machine for bulbs such as garlic,

The pushing head 41 can be pushed simultaneously from above. The pushing cylinder 6 is connected to the implantation pressing electric unit W and is driven by the driving thereof.

  Next, the operation of a bulb planter such as garlic according to an embodiment of the present invention will be described. The planting machine is moved by the power of the traveling motor S to the culm for planting the bulb G such as garlic, but may be transported by the manual force of the operator, and stops at the planting start part of the cocoon M. At this time, the traveling wheel Q travels across the ridge wider than the ridge width. In addition, when planting in the normal four rows, work is done by two workers, but it is arranged on the left and right sides of the heel and one person moves the traveling machine and inserts the bulb, and the other assistant inserts the bulb. In charge. When planting bulbs in two rows with narrow ridges, even one worker can plant.

  In an initial state, the planting holder 1 of one set of eight holder units U is in a state of facing upward, and the other set is in a state of facing downward.

  Bulbs G such as garlic are loaded in the same posture on all the planting holders 1 of the eight holder units U in one set facing upward. An operator attaches bulbs G such as garlic one by one to each planting holder 1 from the bulb mounting table V, but the insertion taper portion of each holding plate-like body 20 of the outer periphery holding portion 2 of the planting holder 1. Therefore, the bulb G such as garlic can be smoothly inserted downward from the budding part A side. Then, all or some of the one curved surface portion C, the two flat surface portions D, and the ridge line portion E that are the outer peripheral portion of the bulb G are sandwiched between the holding portions 23 of the holding plate-like body 20. At this time, the holding portion 23 holds the bulb G such as garlic with the urging force applied to the inner side of the ring-shaped spring 24 that is pushed in the outer peripheral direction but urges toward the inner peripheral side (in the upper part of FIGS. 2 and 3). Holder unit U).

  In this state, the budding part A of the bulb G such as garlic is inserted into the central recess 31 of the deep hole in the center of the concave curved surface. At the same time, the inner peripheral end of the hole is in contact with the lower peripheral surface of the budding part of the bulb G such as garlic, and is securely held. Therefore, the budding part A is not pressed and crushed by the inner surface of the tip concave part 30, and the fixed posture of the bulb G such as garlic is maintained in the vertical and horizontal directions, and the position of the budding part A is maintained and moved. There is nothing.

  This insertion operation is manually performed by the operator, but the left and right sides of all the garlic bulbs G are the same as the garlic bulbs G are vertically oriented, and the ridge line portion E is directed in the row L direction. Hold in the direction.

  After the bulbs G such as garlic are completely inserted into all the eight planting holders 1 of the first set, the operation chain OP is operated to drive the rotation motor 9 of the rotation moving mechanism and to move the movement chain 8 halfway. Then, the tip of the implantation holder 1 of the holder unit U facing downward is stopped at a position facing upward. The stop position is determined by the limit switch operating plate LP coming into contact with the limit switch LM. Then, the operator loads the bulbs G such as garlic in the same posture on the eight implantation holders 1 in the second set.

  At this time, in the first set of holder units U located on the opposite side, the eight implantation holders 1 face downward and are positioned close to the ground surface of the cocoon.

  Next, the implantation pressing electric unit W is driven by the operation panel OP, and the two pushing cylinders 6 are simultaneously operated. Each pushing cylinder 6 extends the cylinder rod 61 and pushes the pushing head 41 of the pushing body 4 by the pushing plate 62. In this embodiment, the pushing cylinder 6 is operated by the electric power unit W for implantation and the pushing head 41 of the pushing body 4 is pushed by the pushing plate 62. In other embodiments, the pushing head 41 may be pushed by the operator's force. A push-in mechanism using a cam, a crankshaft, a link mechanism, or the like using a motor other than the cylinder as a power source may be configured.

  When the pressing head 41 of each pressing body 4 is pressed, the slide shaft 40 moves downward (to the ground side) against the urging force of the pressing spring 43.

  Each pusher 4 and each budding part lower peripheral surface holding part 3 connected at the tip thereof also move downward. At this time, the budding part lower peripheral surface holding part 3 slides while holding the bulbs G such as garlic held by the holding part 23 of the outer peripheral part holding part 2 on the outer peripheral part holding part 2 as it is moved to the ground side. Then, the plant is planted while maintaining the vertical and horizontal orientations of the bulb G such as garlic to a predetermined depth below the ground at the planting position N. Each holding plate-like body 20 of the outer peripheral holding part 2 is pressed slightly outward by contacting the oblique side part 22 from the inside, but is urged inward by the ring-shaped spring 24, so that the bulb G such as garlic The holding slides to the ground while being held. (See FIG. 6).

  Further, the cylinder rod 61 of the cylinder 6 is extended by continuously pushing in, the slide shaft 40 of the push-in body 4 is pushed downward, and the budding part lower peripheral surface holding part 3 is moved downward to enter the hole in the central part 31 of the recess. The held bulbs G such as garlic are pushed to a desired depth (about 5 to 7 cm from the bud surface to the budding part A) and remain in that position. As a result, eight bulbs such as a set of garlic are planted in a total of 8 bulbs, 4 in 4 rows and 2 in each row direction.

  Thereafter, when the cylinder rod 61 is shortened, the slide shaft 40 of the pusher 4 is also moved upward by the urging force of the push spring 43. Accordingly, the budding part lower peripheral surface holding part 3 also moves upward and returns to the original position, but the outer periphery of the concave part 30 at the tip part has the shape of the sloped part 32, so that the holding part 23 of the holding plate-like body 20 is recessed. It is possible to move smoothly upward without being caught.

  After the first set is planted, the switch on the operation panel OP is operated to drive the circling motor 9 of the circling movement mechanism to move the moving chain 8 by half a circle, changing the direction of each set by 180 degrees and planting. At the position where the set of holder units U where the garlic bulbs G are not held are directed upward, and at the same time, the second set of holder units U which hold the garlic bulbs G are directed downward. Stop at position. At this time, the tip of the implant holder 1 is positioned close to the ground surface of the heel.

  Next, the operator drives or manually moves the traveling machine by two planting positions in the row direction. At this time, if the rear steering wheel H is lifted and moved with the front traveling wheel Q as a fulcrum, the bottom surface of the planter body P is separated from the heel surface, so that the movement is easy. In particular, when there is a multi-film covering the heel surface, it is easy to move without being caught by it. This movement distance can be easily confirmed by a planting position gauge Z extending backward from the planting body P.

  After moving to the next planting position, the traveling machine is stopped, and the bulb G such as garlic is inserted and held in the same posture in the third set of eight planting holders 1 facing upward. .

  Next, the planting pressing electric unit W is driven by the operation panel OP, the cylinder rod 61 of the pressing cylinder 6 is extended, and the second facing the ground facing downward in the same manner as in the first set operation. Implant bulbs such as 8 garlic in the holder unit U of the set.

  After the second set planting is completed, the operation panel OP is operated to drive the orbiting motor 9 of the orbital movement mechanism to move the moving chain 8 by a half revolution and change the direction of each set by 180 degrees, An operator drives or manually moves the traveling machine by two planting positions in the row direction.

  Thereafter, the same operation is sequentially repeated, and the bulbs G such as garlic are planted while moving in the vertical direction of the row L of ridges M.

  The present invention is highly applicable to a field of a large planting area for the purpose of planting bulbs such as garlic, particularly for harvesting bulbs such as professional garlic.
