Description

Description: TECHNICAL FIELD The present invention relates to a seedling transplanter having a fertilizer application device, and more particularly to a seedling transplanter for planting seedlings in a field covered with mulch film.

(Prior art and its problems) Conventionally, when transplanting seedlings to a field covered with a mulch film, there has been no technical means for surely opening a seedling planting hole in the mulch film.

(Technical Means for Solving Problems) In order to solve the above-mentioned problems, the present invention is directed to a seedling transplanting position for a seedling transplanter that advances a field covered with mulch film to plant seedlings A. An opening device 29 having an electric heater 40 that opens by burning out the mulch film is provided, and the electric heater 40 of the opening device 29 is electrically wired so that the engine 14 does not heat below a certain rotation speed. It was a transplanter.

(Operation and Effect of the Invention) According to the present invention, since the opening device 29 having the electric heater 40 for burning out and opening the mulch film at the seedling planting position is provided, the mulch film is surely opened and the mulch film is appropriately opened. The seedling A can be planted. Also, opening device
Since the electric heater 40 of 29 is electrically wired so that the engine 14 does not heat below a certain number of revolutions, the electric heater 40 does not operate in the low number of revolutions of the engine 14 below the certain number of rotations in the non-seedling work state. Since the engine 14 is not heated, the power loss of the engine 14 is small, and the aircraft can be driven by the small engine 14 to obtain a small and lightweight seedling transplanter.

10 is an implanter, which is a box-shaped implanter body with a hollow interior 10
In a, two transplanted nails 8 of a transplanted solid nail and a transplantable movable nail are attached, an operating mechanism of the transplantable movable nail is provided inside the transplanter main body, and the seedling A is held by the operator or vice versa. The operation of separating A is performed.

The main body 10a of the implant 10 is pivotally attached to the first rotary case 3, the first rotary case 3 is pivotally attached to the second rotary case 7, and the locus of the tip of the implant nail 8 of the implant 10 is drawn. Make sure that P is narrow in the front-back direction and long in the up-down direction.
A transmission mechanism is built in the rotating case 3 and the second rotating case 7, and the base of the second rotating case 7 is pivotally attached to the transplantation transmitting case 1.

Reference numeral 29 denotes an opening device for driving and rotating a rotary arm 31 whose base end is fixed to a rotary shaft 30 which is driven to rotate by projecting from the transplant transmission case 1 and a support plate fixed to the transplant transmission case 1.
A swing arm 33 pivotally attached to the shaft 32 is provided so as to draw a locus P'where the tip of a cutter 34 fixedly mounted on the tip of the swing arm 33 plunges into the soil at the seedling planting position.

Reference numeral 35 denotes a rear wheel provided at the rear of the machine body, behind the left and right drive wheels 15 and 15, and is supported by a front support member 36 and a rear support member 37 provided in the transplant transmission case 1.

Reference numeral 38 denotes a throttle lever, which is configured to change the engine speed by rotating from a low speed position to a high speed position in FIG.

Reference numeral 39 denotes a sensor, which is provided so as to detect that the detection piece 39a is pressed by the pressing piece 38a of the throttle lever 38 and the throttle lever 38 is at the working speed position.

Reference numeral 40 denotes an electric heater, which is provided inside the cutter 34.

Reference numeral 41 is a main switch of the electric heater 40, and as shown in FIG. 3, the main switch 41, the sensor 39, and the electric heater 40.
Are wired in series, and if the main switch 41 is turned on and the sensor 39 detects that the throttle lever 38 is at the working speed position and is turned on, the electric heater 40 is heated by electricity and heated. .

Reference numeral 42 denotes a centrifugal clutch, which is engaged only when the drive shaft of the engine 14 rotates at a certain speed or more, that is, when the throttle lever 38 is at the working speed position.
Is transmitted to the mission case 11.

Therefore, only when the power of the engine 14 is transmitted to the mission case 11 by the centrifugal clutch 42 and the machine body moves forward to perform seedling planting work, the electric heater 40 is configured so that electricity flows and is heated. ing.

An alternator (generator) 43 is configured to be driven by the power of the engine 14 via the centrifugal clutch 42, and the generated electricity is stored in the battery 44. Therefore, the alternator 43 is driven only when the drive shaft of the engine 14 rotates at a certain rotation speed or more, that is, when the throttle lever 38 is in the working speed position, and is not driven in the low rotation speed region of the engine 14, Even if 14 has low horsepower (low torque), engine stall does not occur and a small and lightweight low horsepower engine can be used.

Further, as is clear from the above, the electric heater 40 is designed so that electricity flows and is heated only when the alternator 43 is driven and generating electricity. In other words, the electric heater 40 consumes electricity. At this time, the alternator 43 is always driven to generate electric power, so that the battery 44 does not discharge and go up.

Reference numeral 45 denotes a planting clutch lever 44, which has a clutch engagement position for simultaneously driving the implanting device 10 and the opening device 29, and an implanting device.
It is configured to be switched to a clutch disengaged position where the opening device 29 and the opening device 29 are stopped at the same time.

Next, explaining the operation of the above example, the drive wheels 15, of the transplanter,
15 is set so as to straddle the transplanted ridges in the field where the entire surface is multi, and the pot-shaped seedlings are cultivated with a paper-made nursery device in which pot containers are vertically and horizontally connected to the seedling supply table 18 at predetermined intervals. Seedling A
When the engine 14 is started and the throttle lever 38 is moved from the low speed position to the work speed position after the
Each of the rotating parts is transmission-rotated via, and the body is propelled by the rotation of the drive wheels 15, 15.

At this time, when the main switch 41 is turned ON and the planting clutch lever 45 is operated to the clutch on position, the rotary arm 31 is rotated by the power of the engine 14 and the tip of the cutter 34 moves up and down to move the seedling planting position. Cut the mulch film, rush into the soil, and make a hole in the ridge. At that time, since the cutter 34 is heated by the electric heater 40, the mulch film is surely burned off neatly.

Since the seedling supply table 18 is reciprocally rocked in the left-right direction via the left-right drive mechanism, the seedling A located on the rear end side is moved left and right while being received by the seedling receiving frame 25, and is transferred to the seedling take-out port. Are sequentially drawn out by the transplanting claws 8 that draw the transplantation locus P and are planted in the ridge planting holes formed by the cutter 34.
