Abstract

PURPOSE:To form a narrow planting hole at the central bottom portion of a wide outer hole to prevent the damages of seedlings on the transplanting of the seedlings and reduce the affection of wind pressure, etc., by disposing a wide portion and a narrow portion in an earth plate for forming plating holes on the surface of oil in two stages. CONSTITUTION:A transplanter frame is driven to form a transplanting hole on the surface (A) of soil with an earth auger plate 1 at a prescribed interval and the root portions of seedlings are planted in the formed trans planting hole. A planting hole is formed in the bottom of the transplanting hole with the narrow of the earth auger plate 1 and a wider outer hole than the planting hole is formed above the planting hole with the wide portion of the earth auger plate 1. The root portions a seedling are planted in the planting hole.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a transplant hole forming device for a transplant machine. Problems to be Solved by the Prior Art and the Invention In transplanting machines for transplanting vegetables, etc., the root portions of the vegetable seedlings, etc. that are inserted into the soil surface during transplanting are likely to be crushed or broken. For this reason, just before transplanting, a transplant hole is made in the soil surface in advance, and the root part of the seedling is inserted into this transplant hole. However, when the transplant hole becomes deep, it is easy to collapse and it is difficult to maintain a stable shape of the transplant hole. Means for Solving the Problems This invention has a wide conduit part for digging a wide outer hole (C) in a hole digging plate (1) that moves up and down to form a transplant hole (mouth) in the soil surface (A). (2) and a narrow part (3) for digging a narrow planting hole (2) in the center bottom of this outer hole (C). By the operation and effect of the invention, as the transplanting machine body travels, transplant holes (mouths) are formed at predetermined intervals on the soil surface (A) by the hole-drilling plate (1).This hole-drilling plate (1) The root part of the seedling is planted in the transplant hole (mouth) formed by Soil level (a)
While scraping in the direction of travel, dig a planting hole (2) with the narrow part (3) at the bottom, and at the same time dig the planting hole (2) with the wide part (2) above this planting hole (2). Dig an outer hole (C) that is wider than the hole (2).This makes the transplant hole (mouth)
It is formed in two stages: a planting hole (2) and an outer hole (C), and the planting of the base of the seedling is done in this planting hole (2). For this reason, even if the transplant hole (mouth) is formed deep, a wide outer hole (c) is formed at the top, which prevents it from collapsing and causing damage to the seedlings during the planting process. Because the seedlings are surrounded by a deep outer hole (c), they are less affected by wind pressure and can maintain a stable transplant posture. Embodiment In the illustrated example, the vehicle body (4) extends from the front end to the rear, including an engine (5), a transmission case (6), a pair of left and right wheel cases (7), and a vehicle that moves the wheel cases (7) up and down. Hydraulic cylinder [8], rear wheel arm (9) that is raised and lowered in conjunction with this wheel case [7], height sensor (to) that detects the height of the soil surface (A), soil surface (A) A hole-drilling board (1) for digging a transplanting hole (mouth) in the hole, a seedling tank 0υ for accommodating and transferring seedlings, and a seedling tank for transplanting seedlings into the transplanting hole (mouth) formed by the hole-drilling board (1). Attached claw 0 [and control handle α
Configure the transplanter by arranging the equipment. (13 is the front wheel that is pivoted on the left and right wheel cases (7), and (to) is the rear wheel that is pivoted on the left and right rear wheel arms +91. By the expansion and contraction control of the hydraulic cylinder (8), the The pair of left and right front wheel cases (7) are moved up and down around the front wheel transmission shaft Tle, and the rear wheel arm (9) is moved around the arm shaft (Fl) via the rond (5) and buffer spring (IB, etc.). The vehicle body (4) is raised and lowered parallel to the soil surface (A) by being moved up and down. , The sensor arm (self) is pivoted so as to be able to move up and down on a nine-layer arm that can freely swing up and down around four spindles provided on the bracket (4) of the vehicle body (4), and protrudes from this height sensor (end). and the hydraulic cylinder {8
} is interlocked with the elevation control valve fin that controls the height sensor (to), and when this height sensor (to) moves upward beyond a certain range, it descends relative to the front and rear wheels 0104 & vehicle body <<4>> By moving the vehicle body (4) to the surface, and conversely by lowering it beyond a certain area, raising the front and rear wheels (13 Q4) and sinking the vehicle body (4), it is lifted to the ground The control is interlocked to maintain a constant height above the surface (a).The anabori board (1) has a narrower width part +31 protruding from the center of the lower edge of the wide part (2), and the upper and lower parts Pivot the second position to the rear end of the up link (to) and the down link (to) 01) 021
L, the bases of these upper links (to) are pivoted on eccentric shafts (to), and the front end bottle (to) is slidably guided to the guide hole (to) provided in bracket n, and the lower links are (to) is pivoted to the lower part of the bracket (to), and the eccentric shaft (to) is pivoted to the bottom of the bracket (to).
The structure is such that a transplant hole (mouth) is formed in the soil surface (a) by moving the hole-drilling plate (1) up and down in a fixed trajectory by rotating the hole (to). This transplant hole (mouth) is set at a position opposite to the groove formed by the above-mentioned height sensor (self). The target is the bracket that attaches the hole board (1) to the upper and lower links (to). The seedling planting device operates the seedling tank 0υ located at the upper center of the vehicle body (4) and the seedling separation opening (toward) at the rear end of the tank from the upper side into the soil below to separate and transplant the seedlings. This seedling tank 0υ consists of a planting claw 0[I, and this seedling tank 0υ is equipped with a delivery belt (end) on the bottom that receives and sends out the stored seedlings, and is reciprocated left and right with respect to the seedling receiving frame ridge that forms a seedling separation opening (end). It is configured to be linked so that it can move. The seedling planting claw 0 is installed at the tip of the planting case 6B, which rotates up and down, so as to transmit the rotation.
Grasp the bedding part (a) from the left and right, and while separating from the seedling separation mouth part (to), plant into the planting hole (2) of the transplant hole (mouth) formed in the soil surface (a) below. It is configured in a related manner so that it is attached. (Ten) is a lever that adjusts the detection position of the height sensor handle, and it protrudes backward from the support shaft (To) of the arm (C).
Adjustment groove. You can operate it by letting io guide you. When this height sensor wire is raised, the depth of the transplant hole (mouth) made by the hole-hori plate (1) becomes deeper, and the depth of planting by the planting claw (gull) also becomes deeper. By increasing the depth of the opening (opening) and increasing the width of the outer hole (c), the seedlings (e) transplanted into each planting hole (2) were completely sunk into this transplanting hole (opening). Then, as shown in Figure 8, the upper side can be covered with a mulch film ■.
