Description

[Detailed Description of the Invention] Industrial Application Field The present invention allows the planter part supported by the machine body to move up and down, even if the planting surface on which the seedlings are transplanted has heights, so that the planting depth remains constant and accuracy is always maintained. This invention relates to a transplanting machine that enables good transplanting work.

Conventional technology Transplanting machines that are generally used when transplanting sweet potato seedlings, etc. are those that use tweezers-like clamping claws provided on the planter section to pinch the base of the seedling and insert it into the soil in the ridge. It has been known.

Problems to be Solved by the Present Invention However, with such conventional transplanters, if the planter section is adjusted before starting work so that the transplanted seedlings are at the desired planting depth, then the planter is not returned to the adjusted position. Since the transplanting process continues while the machine is fixed, the height of the ridge on which the seedlings are planted varies, and the bottom of the groove where the machine runs over the ridges is uneven, causing the machine to move up and down as a whole. If there is any movement, the distance between the planter part and the ridge surface will change, and the planting depth of the seedlings and the length of the planting hole with the multi-cutter will not be constant, making it difficult to perform accurate transplanting work. There is a drawback that it cannot be done.

The present invention has been devised to solve these drawbacks in view of the above-mentioned actual situation, and is intended to solve the above-mentioned problems. The object of the present invention is to provide a transplanting machine that can accurately move the planter part up and down to accommodate unevenness and perform transplanting work with a constant planting depth and high precision. be.

Means for Solving the Problems In order to achieve the above object, the technical means taken by the present invention are to provide a traveling aircraft that straddles a ridge,
A planter section for planting seedlings on a ridge is mounted so as to be movable up and down, and a detection mechanism is provided at the front of the planter section to detect the height of the ridge surface, and the planter section is moved up and down in conjunction with the detection by the detection mechanism. The invention is characterized in that a mulch cutter for forming planting holes in the vinyl mulch and a pressure roller for suppressing the planting surface are provided behind the detection mechanism. .

Effects of the Invention Next, the effects of the present invention configured as described above will be explained. Now, if the machine is run across the ridge, seedlings can be planted on the ridge using the planter section attached to the running machine. If the height of the ridge is uneven, or if the bottom of the groove where the aircraft runs is uneven and the aircraft moves up and down, the detection mechanism installed at the front of the planter detects the distance between the planter and the ridge. It accurately senses changes in the area and moves the planter up and down in conjunction with this. Next, a mulch cutter installed behind the sensor forms a planting hole of a certain length in the vinyl mulch, and the planter section plants the seedlings at the desired planting depth, and then a pressure roller plants the seedlings. Since the surface is compressed, planting work can be carried out with high precision and in an orderly manner.

Embodiments The configuration of the present invention will be described with reference to embodiments shown in the drawings. Reference numeral 1 denotes a fuselage frame having a front wheel 2 and a rear wheel 3, and an engine 4 mounted at the rear thereof. 8 so that it can move vertically in parallel. Reference numeral 9 denotes a rotating shaft provided in the planter section 5, and the bracket 8 is rotated by the drive shaft 11 of the transmission 10.
It is rotatably driven through a sprocket 12 pivotally supported by a sprocket 12, a sprocket 13 pivotally attached to a rotating shaft 9, a chain 14 suspended from these, and the like. Reference numeral 15 denotes a transplanting body attached to a mounting arm protruding from the rotating shaft 9, and the outer surface of the transplanting body 15 is formed in a curved shape to form a seedling supply surface 15 for holding sweet potato seedlings and the like.
a, and the seedling supply surface 15a side of the planting body 15, which rotates as the machine moves, sinks into the soil of the ridge b to plant the seedlings a.

Reference numeral 16 is a detection mechanism for detecting the height of the ridge b, and a rotary arm 18 that pivotally supports a sensor roller 16a is attached to the tip side of an arm 17 that projects forward from the planter section 5, and is movable up and down. An angle detection sensor 19 is attached to the rotation shaft of the rotation arm 18, and the height of the ridge b surface in contact with the sensor roller 16a is set at the planting position set before the start of work. When the rotation arm 18 correspondingly rotates upward by θ ₁ ° or more or downward by θ ₂ ° or more, the angle detection sensor 19 It senses this and issues a signal. The actuator 20 attached to the bracket 8 is actuated by the signal from the angle detection sensor 19, swings the upper and lower links 6 and 7, and moves the planter section 5 up and down until the angle detection sensor 19 no longer emits a signal. The distance between the planter portion 5 and the ridge b is kept constant within the allowable range ±l.

21 is a planting hole in vinyl mulch c covering ridge b
c', which is installed in the planter section 5 so as to be located behind the sensor 16, and swings up and down by a cam fixed to the rotating shaft 9 to cut the seedlings a. A planting hole c′ is opened at a predetermined position for planting. Further, a pressure wheel 22 for pressing the surface of the ridge B is attached to the rear part of the planter section 5, and is adapted to suppress the soil around the planted seedling a. 23 is a handle for turning the aircraft on the headland, and 24 is a seat.

In the above configuration, in order to transplant sweet potato seedlings or the like, first, the distance between the planter section 5 and the ridge b surface is adjusted so that the transplanted seedlings have a desired planting depth. Next, when the driver sitting on the seat 24 feeds the seedlings to the planting body 15 while running the machine while straddling the ridge B, the multi-cutter 21, which swings up and down as the machine runs, will feed the seedlings. The seedlings a held on the seedling supply surface 15a can be planted in the planting holes c' thus formed. During the transplanting process, even if the height of the ridge b changes by more than the allowable value ±lmm, the rotating arm 18 will rotate upward by θ ₁ ° or more or downward by θ ₂ ° or more in response to the change. The angle detection sensor 19 detects the movement and issues a signal, and operates the actuator 20 to move the planter section 5 up and down until it no longer issues a signal.
and the ridge b can be maintained at the interval adjusted before starting the work. Therefore, the transplanted seedlings can always be planted at the desired planting depth, and the length S of the planting hole c' formed by the multi-cutter 21 is also constant, making it possible to significantly improve the planting accuracy. The surroundings of the planted seedlings a are suppressed by a suppression wheel attached to the rear of the planter part 5, so that the transplanting work can be carried out in an orderly manner. Moreover, the sensor roller 16a is
Arm 17 located in front of multi-cutter 21
Since it is attached to the tip side of the ridge, it comes into contact with the ridge B surface before it is disturbed by the multi-cutter 21 and the transplanting body 15, and the height of the ridge B surface can be accurately sensed. The attachment accuracy can be significantly improved.

A detection mechanism is installed to detect the height of the
In conjunction with the detection by the detection mechanism, the planter section is moved up and down to control the planting depth, and behind the detection mechanism is a multi-cutter that forms planting holes in the vinyl mulch, and a mulch cutter that cuts the planting surface. Since a pressure roller is installed to suppress the seedlings, if you adjust the distance between the planter section and the ridge before work so that the transplanted seedlings have the desired planting depth, the height of the ridge will change during the work. Even if there is a problem, the planter section can be automatically moved up and down in conjunction with the detection by the detection mechanism, and the distance between the planter section and the ridge can be maintained at the distance adjusted before work, so the desired distance can always be maintained. Not only can the planting depth be adjusted to the same depth, but the length of the planting hole can be made constant using the multi-cutter, and the area around the transplanted seedlings is then pressed down by the pressure roller, so you can transplant the seedlings in an orderly manner just by running the machine across the ridge. Able to perform work. Furthermore, the detection mechanism installed at the front of the planter section can accurately detect the height of the ridge surface before it is disturbed by the multi-cutter or the planter section, thereby significantly improving planting accuracy. etc., it has extremely useful novel effects.
