Description

[Detailed explanation of the invention] (1) Industrial application field This invention relates to a device (an automatic green onion transplanter) that continuously transplants green onion seedlings onto a vast field (long ridges).

(2) Prior art To transplant green onion seedlings, trenches are prepared in advance, and then the plants are lined up at small intervals of 2.5 to 3 cm and covered with soil, and the roots of the seedlings are held down to prevent them from falling over.

Traditionally, all of this porting work was done manually.
In addition, the transplanting period is from early May to late May for early cultivation, but from mid-July to mid-August for late cultivation.

(3) Problems to be solved by the invention Manually transplanting green onion seedlings is carried out in long and wide rows, which causes back pain and other malfunctions, and delayed planting requires work under the hot sun. This causes severe fatigue and significantly impedes work efficiency.

(4) Means for solving the problem In order to solve the above problem, this invention has a vibrating hopper attached to the vehicle frame equipped with wheels driven by a prime mover and a ditch removal plate, and a vibrating hopper at the discharge port of the hopper. is connected to a vibrating inclined plate, etc., and the hopper discharge port and vibrating inclined plate, etc. are dimensioned so that onion seedlings can pass sideways, and the vibrating plate of the vibrating inclined plate, etc. has teeth that protrude intermittently from below. is equipped with multi-stage comb teeth facing in the width direction of the diaphragm, one end of the conveyor belt for picking and transporting green onion seedlings faces the discharge part of the slanted plate, etc., and the other end is used to remove earth from the excavation plate using the excavation plate for trenching. The vehicle body frame is equipped with a soil-covering platform to cover the base of the green onion seedlings that have been propped up against the soil embankment. This is an automatic green onion seedling transplanting machine equipped with soil pressing plates.

(5) Function The ditch removal platform attached to the moving vehicle body creates a planting ditch and an embankment by removing soil, and the green onion seedlings put into the hopper are discharged little by little and raised on the slope. The slanted plate is supplied to a plate, etc., but the slanted plate is provided with comb teeth in multiple stages in the sloping direction, the teeth of which are oriented in the width direction of the diaphragm. The green onion seedlings are oriented sideways to ensure that they are placed one by one on the conveyor belt, and the onion seedlings that have been conveyed are released towards the earth discharge embankment and are placed against the embankment. Next, the roots of the green onion seedlings are covered with soil using a soil covering plate, and the covered soil is pressed down with a soil holding plate, and the green onion seedlings are transplanted at predetermined small intervals.

(6) Embodiment In FIGS. 1 and 2, reference numeral 1 denotes a vehicle body frame equipped with iron wheels 3 driven by an engine 2 and a ditch removal plate 4. Although the earth removal plate shown in the figure is plow-shaped, it may also be a rotary claw type.

Reference numeral 5 designates a hopper installed on the vehicle body frame 1, and an inclined plate 8 is provided at the outlet 6 (chute 7) of the hopper.
A flat cylindrical guideway 9 is connected to the tip of the inclined plate in a hanging manner.

Hopper outlet 6, inclined plate 8 and taxiway 9
Green onion seedlings (grass height 25-30mm, thickness approx. 0.7mm)
The guideway 9 is designed to have dimensions that allow it to pass sideways, and the guideway 9 has a narrow gap through which only one green onion seedling can pass through.

At the tip of the discharge port 6 (and chute 7) of the hopper, there are adjusting plates 10 and 11 for adjusting the amount of onion seedlings flowing out.
A vertical rail 12 is provided on the inner bottom of the hopper to facilitate the outflow of green onion seedlings.

The hopper 5 and the inclined plate 8 have a pulley 1 on the bottom surface.
3 and 14 are attached, and a V belt 1 is installed between these pulleys and the pulley 16 of the auxiliary engine 15.
7 and 18 are hung, and an eccentric weight 19 is attached to the pulleys 13 and 14, and the hopper and the inclined plate are vibrated by the drive of the auxiliary engine 15.
The green onion seedlings 20 in the hopper are smoothly sent out to the discharge port 6, and the green onion seedlings supplied to the inclined plate 8 are arranged in approximately one row and flow down.

Further, below the inclined plate 8, there are comb teeth 22 that intermittently protrude toward the oblong holes 21 formed in the floor plate part of the inclined plate.
are provided in multiple stages in the direction of the slope of the sloped plate, and correct the orientation of the green onion seedlings flowing down the sloped plate to the correct sideways orientation. 23 is a substrate for the comb teeth 22, 24 is an arm provided on the lower surface of the substrate, 25 is a cam that contacts the roll 26 at the lower end of the arm, and the cam 25 utilizes the rotational force of a belt for inserting and transporting onion seedlings, which will be described later. and rotate.

Immediately below the guideway 9, one end of a belt for inserting and transporting onion seedlings, which consists of a pair of belts 27 and 28 that rotate in parallel, is exposed, and the other end of this belt is used for removing soil for trenching. The planting groove 29 formed by the board 4 is oriented perpendicularly to the discharged soil embankment 30, and the green onion seedlings discharged one by one from the guideway 9 are inserted into the discharged soil embankment 30. Release it so that it stands upright.

Reference numeral 31 in the figure is a transmission gear that rotates both belts together, which can be seen in FIG.

Further, 32 is a green onion seedling receiving groove formed on the outer surface of the belt 27, and 33 is fixed to the belt rotating roll.
A grooved plate corresponding to the groove 32, 34 a swinging rod with which the roll 35 at one end comes into contact with the grooved plate, 36 a separation of the wall on the lower end side of the taxiway 9 that moves forward and backward with the swinging of the swinging rod 34. The wall is a holding plate for green onion seedlings, and when one green onion seedling in the guideway enters the groove of the belt, the flow of other green onion seedlings stops, and the belt securely holds the green onion seedlings one by one. Transport together.

A wheel 37 rotates together with the drive shaft 38 of the belt 27, and has ribs 40 on its circumferential surface for forming green onion seedling receiving grooves 39 in the earth removal embankment 30.

When the green onion seedlings are propped up on the earth removal embankment 30 in this way, the soil is gathered at the base of the green onion seedlings using the earth covering plate, and then the soil is transferred to the soil holding plate 41.
I'm going to hold it down.

42 is a sled attached to the rear end of the vehicle body frame 1 that floats the vehicle body by sliding on ridges instead of wheels;
Reference numeral 3 indicates a handle, and reference numeral 44 indicates a lever for adjusting the elevation angle of the earth removal board 4.

(7) Effects A planting ditch with an earth embankment on one side is created in advance by the trench removal platform attached to the moving vehicle body, and at the same time, the green onion seedlings in the hopper are fed sideways to the inclined plate, etc. The green onion seedlings are then inserted one by one into a conveyor belt and discharged toward the earth removal embankment.The onion seedlings are then placed against the earth embankment and covered with soil and pressed down automatically and continuously. but,
Since the vibrating inclined plate has comb teeth protruding intermittently from below, each green onion seedling is reliably arranged sideways and arranged in a single row on the lower side of the inclined plate, so that the conveying belt for holding the green onion seedlings can be used. (or the supply to the taxiway between the belt and the belt) can be reliably regulated to one line at a time, making it possible to securely limit the supply to one line at a time.
It is possible to ensure accuracy when transplanting the device upright.
