First, an embodiment of the present invention will be described in detail for the walking type transplanter shown in FIGS.

FIG. 1 is a side view of a transplanter showing an example of a configuration to which the invention is applied, and FIG. 2 is a plan view thereof.
The transplanter 1 can adjust the body height and the left and right heights through an integrated engine 2 and a main transmission case 2a, left and right front wheels 4 and 4 supporting the front part of the body, and left and right transmission support parts 5a and 5a. Left and right drive wheels 5 and 5 for driving support, a handle frame 3 integrally extending from the rear portion of the main transmission case 2a, a traveling portion 1a including a steering handle 3a integrally formed at the rear end thereof, and seeds such as potatoes It is comprised from the planting part 1b for planting the bulbous bulb A containing a sea urchin or a rakkyo in a farm field. It should be noted that the side of the transplanter 1 where the engine 2 is provided is the front part of the body and the steering handle 3a side is the rear part of the body. The right side is the right side of the aircraft.

  The planting part 1b accommodates the bulb A and accommodates the storage case 20 provided with a delivery device 23 for sending out the bulbs A one by one from the outlet 21. The planting apparatus 7 includes a planting hopper 7a for planting operation. It consists of soil covering pressure reducing wheels 8, 8, etc. behind the planting device 7.

  The delivery device 23 in the housing case 20 has a configuration in which a transport body 25 provided with a transport protrusion 26 is wound around upper and lower feed drive bodies 27 and 28 pivoted on the left and right side walls. One bulb A is sandwiched between the upper and lower conveying projections 26 with a width of one A and conveyed. The transport body 25 is composed of a timing belt with a protrusion, and the feed drive bodies 27 and 28 are composed of timing pulleys engaged with the timing belt, or the transport body 25 is composed of a chain and the feed drive bodies 27 and 28 are sprockets. It is constructed so that the bulb A is surely fed.

  The delivery device 23 is provided close to the inner front wall of the storage case 20, and the bottom of the storage case 20 is inclined downward toward the lower portion of the delivery device 23 so that the bulbs A can easily roll and remain on the transport protrusion 26. I try to take it out. In addition, the left and right side walls of the storage case 20 are narrowed toward the lower part of the delivery device 23 so that one bulb A is scooped up by the transport protrusion 26 and moves horizontally to the outlet 21 provided at the bottom of the storage case 20. A shutter 24 that opens and closes is provided. The shutter 24 is opened at the timing when the planting body 7b of the planting device 7 is raised.

  Since the shutter 24 receives one bulb A, the shutter 24 is provided with a weight sensor, and the carrier 25 is driven until the weight sensor detects the weight of one bulb A, and the weight of the bulb A is measured. When detected, the transport body 25 is stopped.

  In addition, without providing the shutter 24 at the outlet 21, the transport body 25 moves at the timing when the planted body 7b of the planting apparatus 7 moves up, and the bulb A is dropped from the outlet 21 onto the planted body 7b. You may make it supply.

  The remaining bulb A is immediately visible from the outside by making the peripheral wall of the housing case 20 transparent or translucent. Further, a supply base 29 is attached to the housing case 20 from the front or the left and right sides of the machine body so that the bulbs A can be supplied to the housing case 20. The supply table 29 is fixedly attached or can be appropriately attached and detached.

  Next, with respect to the soil covering pressure reducing device, as shown in an enlarged side view (a) of the main part in FIG. 4 and a rear view (b) thereof, the front side of the planting hopper 7a of the planting device 7 on the pressure reducing wheel support frame 31 is shown. The pressure-reducing wheel arm 32 acting from the side is pivotally supported, and the covering soil pressure-reducing wheels 33a, 33a are cantilevered without interference with the planting device 7. When the planting hopper portion 7a of the planting device 7 is lowered by the pressure reducing wheel arm 32, the soil covering pressure reducing wheels 33a and 33a are raised, and when the planting hopper portion 7a is raised, the soil covering pressure reducing wheel 333a is adjusted by a spring 34 capable of adjusting the soil covering pressure. 33a is configured to act. It should be noted that pressure-reducing wheels 33a and 33a are equipped on both sides of the soil covering pressure-reducing wheel 33, and when the planting hopper portion 7a does not act, the heel surface is hardened as a pre-repression. Covering from both shoulders of the planting position with the pressure wheels 33a, 33a on both sides makes it less likely to affect the planting posture. Pre-crush with the central crush wheel 33.

  Next, with respect to the planting hopper 7a of the planting device 7, as shown in the perspective view of FIG. 5 and the side view of FIG. 6, the planting body 7b at the front and rear of the lower end opens back and forth along the aircraft traveling direction. Although it is a general structure, the large opening 7c is provided in each front-and-back wall of the front and back planting body 7b from the upper part to the lower part. In addition, a cylindrical plant guide guide 7d having a lower end made of resin that is elastically deformed from an upper cylindrical portion that does not open and close is provided in the front and rear planted bodies 7b up to near the lower portion of the front and rear planted bodies 7b. (The planting guide 7d has such a length that the bulb A as a planting just enters between the lower end thereof and the lower ends of the front and back planting bodies 7b) The object guide 7d is formed in a bowl shape with a gap.

  Accordingly, since the front and rear walls of the front and rear planted bodies 7b are provided with large openings 7c from the upper part to the lower part, when the front and rear planted bodies 7b enter the field and open, there is less soil resistance and smoothness. When opening, the soil enters the front and rear planted body 7b from the opening 7c and covers the planted bulb A. When the planting device 7 moves up, the bulb A is hooked. However, since the soil is above the bulb A, it can be easily and properly covered, and a good bulb A can be planted.

  In addition, since the front and rear planted bodies 7b are provided with cylindrical planted guide guides 7d having a narrow bottom end made of a resin that is elastically deformed, close to the lower portions of the front and rear planted bodies 7b. A is properly guided to fall down to the lower ends of the front and rear planted bodies 7b. However, the bulbs A that fit in the lower ends of the planted bodies 7b are formed by the tubular planted guide guides 7d whose lower ends are narrowed. Upward movement is prevented at the lower end, and the planted body 7b is held at an appropriate position at the lower end until planting and is planted properly. Since the planting guide 7d is formed in a bowl shape with a gap, when the front and rear planting bodies 7b are opened, the soil that enters the front and rear planting bodies 7b from the opening 7c is planted with bulbs. It is possible to avoid the situation that the bulb A is caught and lifted when the planting device 7 is moved upward as described above, and the covering soil is on the bulb A. Therefore, it can be carried out easily and properly, and a good bulbous plant A can be planted.

  In the above example, the front and rear planted bodies 7b open back and forth along the aircraft traveling direction. However, when the left and right planted bodies 7b are opened to the left and right with respect to the aircraft traveling direction, If the left and right side walls of the right and left planted bodies 7b are similarly opened, the left and right planted bodies 7b are opened smoothly with little soil resistance when they enter the field and opened. The soil enters the right and left planted bodies 7b and covers the bulbs A to be planted, and when the planting device 7 moves up, the situation where the bulbs A are caught and lifted can be avoided, However, since the soil covering the bulb A is covered with soil, it can be easily and properly performed, and a good planting operation of the bulb A can be performed.

Here, the operation of planting the potato seed pod A on the vine in the field with the above-described walking type transplanter will be described.
First, the machine body is put in a field, the left and right drive wheels 5, 5 and the left and right front wheels 4, 4 are in a state of straddling the straw, and the potato seed pod A is put in the storage case 20. Then, the operator performs the steering operation by grasping the steering handle 3a while walking on the rear side of the aircraft.

  As the machine runs, the delivery device 23 takes out the bulbs A in the storage case 20 one by one and supplies them to the planting body 7b of the planting device 7, planting them in the field with the planting body 7b, and planting them with the cover soil pressure wheel 33. Fill the hole.

Thus, since the operator can perform the planting work simply by operating the aircraft, the work can be performed easily and efficiently, and the planting work can be performed easily and efficiently.
