Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a fertilization seeding machine, and more particularly to a fertilization seeding machine that can sow different types of seeds in rows on a fertilized field.

[Prior art] A fertilizer seeding machine is an agricultural machine that applies fertilizer and sows seeds in rows onto a field.The sown crops grow in an orderly manner, so it is important to manage their growth and harvest. You can make your work more convenient. Among these crops, when growing grass and other crops, it is recommended to sow seeds with different characteristics at the same time and use mixed cropping, due to differences in soil conditions within the field, coping with climate change, nutritional balance as feed, etc. is considered desirable.

In order to sow seeds at the same time, if two different types of grass seeds, for example seeds of the leguminous family and seeds of the leguminous family, are mixed in advance at a predetermined ratio and sown in the same row (mixed sowing), the grass seeds of the leguminous family will be dominant. As a result, the growth of seeds of the Physaceae family is hindered at an early stage, making it impossible to achieve the purpose of mixed cropping.

For this reason, the present inventors proposed a fertilizing seeding machine that can sow two types of seeds in rows (mixed row seeding) without mixing them, which was difficult with conventional fertilizing seeding machines. Utility Model Application Publication No. 61-201504).

As shown in FIGS. 5 and 6, this fertilizer seeding machine has a seed hopper b for storing seeds to be sown on the machine body a, in the width direction of the machine body a, that is, in the pulling direction A. They are characterized by being arranged in parallel along the direction perpendicular to the
Seed feeding means d provided at the feeding opening c of the hopper b
and a driving means e for driving these. This seed hopper b is placed on the machine body a together with a fertilizer hopper h which similarly includes fertilizer feeding means f and driving means g. In addition, at the bottom of the main body a, there are running wheels i for driving over the field F while being towed by a tractor (not shown).
and a pressure wheel j for covering the sown seeds with soil.

The seed dispensing means g receives the seeds coming out of the dispensing port c into a groove (not shown) formed on its circumferential surface, and is a transverse groove type dispensing means for sequentially dispensing the seeds downward from the hopper b by rotation. A roll k, an adjustment dial l provided on each roll k to adjust the volume of the groove, a seed drive shaft m for inserting the axis of the roll k to support them, and a seed seed being fed out by the roll k. The seed conduit n is configured to guide the collected seeds to the top of the field F.

In order to sow seeds in synchronization with field running, the drive means g includes a sprocket p provided on the axle o of the running wheel i, a sprocket q provided on the seed drive shaft m, and a sprocket q provided on the axle o and the drive shaft m. It consists of an intermediate shaft r and a sprocket s interposed between the sprockets p, q and s, and a chain t stretched between the sprockets p, q and s.

The fertilizer feeding means f and its driving means g similarly include a roll, a dial (not shown above), a drive shaft u, a fertilizer conduit v and a sprocket w, and a chain x.
have. In addition, in this conventional example, a pressing wheel y for forming a seed bed is also provided.

With the above configuration, especially when sowing mixed crops in rows, seeds having different properties, for example, seeds of the leguminous family and seeds of the leguminous family, are alternately accommodated in the seed hopper b arranged side by side. and individual hotsupa b
Each time, adjust the feed roll k by operating the dial l to obtain the desired feed amount. When the machine body a is towed and starts running, the drive shaft m is driven by the drive means e and the roll k is rotated.
The seeds are delivered to the seed conduit n and sown on the field F. At the same time, fertilizer is applied and soil is covered.

By fertilizing and sowing in this way, seeds of the type and amount that the corresponding hopper accommodates can be sown at each seed hopper arrangement position on the field, in other words, in rows at an arbitrary ratio. Different species of seeds will be sown, and the grass will grow without any mutual influence due to the properties of the seeds (with a good co-growth rate).

[Problems to be solved by the invention] However, although the above proposal improves the co-synthesis rate compared to mixed sowing, it is still difficult to perform seeding that appropriately corresponds to the various soil properties in the field. It was hot.

The reason for this is that the sowing ratio of different seeds is determined by the amount of delivery of each hopper b and the arrangement of the hopper b in which each hopper is accommodated, so if you want to change the sowing width of each seed, you can independently This is because it is necessary to replace the seeds in each hopper b. In other words, for example, when you want to perform row mixed sowing at a ratio of 1:3, seeds are placed in a number of hoppers b corresponding to 1/4 of all hoppers b, and in a number of hoppers b corresponding to 3/4 of all hoppers b. Work will be required to accommodate the

In order to avoid this, if you try to adjust the amount of each individual feed without changing the seed storage arrangement in the hopper b, it is necessary to accurately calculate the desired amount of feed by taking into account differences in seed particle size, etc. Dial l provided for each hopper b must be operated, making it difficult to perform the work smoothly. Furthermore, since seeds are sown in anticipation of the amount that will die, the amount of seeds used is likely to be excessive.

In view of the above-mentioned circumstances, the present invention was devised to provide a fertilizing and seeding machine that can perform appropriate and smooth row-type mixed crop sowing.

[Means for Solving the Problems] The present invention provides a fertilization and seeding machine that is towed by a tractor or the like and applies fertilizer and sows seeds in multiple rows on a field along the pulling direction. hoppers provided in multiple stages in the traction direction to accommodate each fertilizer, a large number of dispensing ports arranged at predetermined intervals along the machine width direction at the bottom of these hoppers, and aligned in the traction direction, and these dispensing ports. It is provided with a feeding means for selectively opening in the pulling direction for each alignment position.

[Operation] With the above configuration, when performing row mixed sowing at an appropriate ratio corresponding to the soil properties of the field, seeds with different properties are housed in the hoppers provided in multiple stages. Then, the feeding means opens and closes the feeding port of each hopper as appropriate. The seeds in the hopper on the side where the outlet is open are sown in rows,
It will not be seeded in closed positions.
In this way, each seed is sown in rows according to the opening and closing of the outlet, resulting in mixed cropping at a desired ratio.

[Examples] Examples of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows an embodiment of the fertilizing and seeding machine according to the present invention, and the hopper 1, which is a feature of the present invention, extends in the width direction of the machine body 2, that is, in the direction orthogonal to the traction direction A. The seed hopper 3, which is formed so as to extend over the field and accommodates the seeds B to be sown in particular on the field F, is constructed of a front hopper 5 and a rear hopper 6, with a partition plate 4 provided in two stages. ing. Then, each hopper 5, 6 has a feeding device 1 in a feeding port 8, 9 provided at the bottom 7 thereof.

As shown in FIG. 2, the outlets 8 and 9 are equally spaced along the longitudinal direction of the seed hopper 3, that is, the direction perpendicular to the pulling direction A. Therefore, these outlets 8 and 9 are in the traction direction A.
They are also arranged in pairs.

Below that, an opening/closing shutter 29 constituting the feeding means 10 is provided so as to be movable back and forth in the pulling direction A. The opening/closing shutter 29 is formed as a rectangular plate having an opening equal to or larger than the outlet ports 8 and 9 so that only one of the outlet ports 8 and 9 can be opened. A driving means 1 is located outside the bottom 7 of the seed hopper 3 where these opening/closing shutters 29 are arranged in parallel, that is, outside the machine body 2.
A gear 30 for inputting driving force from 7 is provided to mesh with a gear 31 provided on the rotation shaft 21.

As shown in FIG. 3, the flow rate control means 11 includes a rotary feeder 32 provided below the outlet ports 8 and 9, and a control rod 33 that extends through the axis of the rotary feeder 32 to support it. It is made up of.

The rotary feeder 32 has a groove portion 34 formed by suitably recessing the periphery in order to place the seeds B, and a groove portion 34 that is formed by appropriately recessing the periphery in order to place the seeds B.
It is inserted into the relay pipe 36 that relays the shutter 29 and the seed conduit 12 in its axial direction, that is, in the direction orthogonal to the pulling direction A. It penetrates through and is fitted rotatably in the circumferential direction, that is, in the traction direction A.

One end 37 of the control rod 33 is pivotally supported by a bracket 39 which is stretched over one side 38 of the hopper 3 via an adjustment dial 40. This adjustment dial 40 controls the control rod 33 in the axial direction, i.e.
By reciprocating in a direction perpendicular to the pulling direction A, the groove portion 34 is moved into or retreated from the inside of the relay pipe 36 to adjust the groove volume on which the seeds B are placed and to bear the rotation for feeding out. It's getting old. The bracket 39 is also provided with a lock nut 41 for stopping the adjustment rotation of the dial 40 from loosening.

Further, the other end 42 of the control rod 33 is connected to a drive shaft 43 for rotating the control rod 33. This drive shaft 43 is attached to a bearing member 4 on a bracket 45 stretched on the other side 44 of the hopper 3.
A control rod 33 is rotatably supported via a control rod 33 at the end 47 on the side of the outlet 8 and 9.
An elongated hole 49 is formed into which a pin member 48 provided at the other end 42 is loosely fitted in the axial direction and is locked in the rotational direction of the control rod 33 around its axis. A gear 30 connected to the drive means 17 is fixed to the outer end 50.

Next, the operation of this embodiment will be explained.

First, in the front hopper 5 and rear hopper 6 of the seed hopper 3, seeds B having different properties,
For example, grass seeds of the leguminous family and grass seeds of the legume family may be stored in arbitrary amounts. Then, it is pulled by a tractor in the pulling direction A, and when it reaches a predetermined field F, the ratio suitable for the soil properties is changed, for example, leguminous 1:
Mixed cropping will be sown in rows in main course 2.

This can be easily done by operating the opening/closing shutter 29 as appropriate. That is, the front hopper 5 for housing leguminous seeds.
Shutter 29 whose outlet 8 is open
The respective shutters 29 are moved back so that the ratio of the number of shutters 29 to the number of shutters 29 which open the outlet 9 of the rear hopper 6 for storing seeds of the Oryzae family is 1:2. Further, the flow rate control means 11 adjusts the flow rate of the seeds fed out from the respective feeding ports 8 and 9 to be all the same. After adjusting in this way, when the main body 2 is run, the drive means 17 rotates the rotary feeder 32 and sows each seed B sequentially onto the field F.

Moreover, when it is desired to slightly correct the seeding ratio once set, the rotary feeder 32 is slightly moved by rotating the adjustment dial 40 to adjust the desired feeding amount.

Then, when arriving at a field F having different soil properties, the opening/closing shutter 29 and adjustment dial 40 are similarly operated to sow mixed crops in rows at an appropriate ratio.

As explained above, by storing two types of seeds in advance in the two-tiered seed hopper and then operating the opening/closing shutter that constitutes the feeding means, it is possible to easily form rows with any different ratio of seeds. Mixed sowing can be done.

In addition, the flow rate adjustment, which was conventionally performed for each rotary feeder, is now performed by a control rod inserted through the axis of each rotary feeder, so different ratios can be adjusted by operating the adjustment dial provided on the control rod. Corrections can be easily made, and uniform seeding can be performed without any error in the flow rate from each outlet.

[Modification example] FIG. 4 shows a modification of the above embodiment.

In this modified embodiment, a shaft 51 shaped like a screw conveyor is provided inside the seed hopper 3. The shaft 51 is provided near the upper side of the outlet ports 8 and 9 arranged in parallel in the longitudinal direction of the hopper 3, is rotatably supported outside the hopper 3, and can be driven as necessary. , are connected to the drive means 17.

The shaft 51 formed in this way is in a state similar to the bridging phenomenon that is expected to occur when the feeding ports 8 and 9 are opened every two times or less frequently, that is, the seeds B that are not flowed out are closed. Feeding outlet 5
While remaining in the hopper 3 on the hopper 2, by rotating around its axis, the remaining seeds B are moved in the axial direction and flowed out from the open outlet 53,
Smooth seeding work can be continued.

In addition to the hopper provided with a partition plate as in the embodiment described above, independent hoppers may be arranged in parallel. In addition to having two stages, it may be three or more stages as necessary, and a feeding means may be appropriately provided to perform desired seeding. Further, although omitted in the description of the embodiment, fertilizers are applied sequentially as the vehicle travels, and it is also possible to apply different types of fertilizers in multiple stages.

Further, the flow rate control means and the driving means are not limited to the configuration shown in this embodiment, and even if the shape of the rotary feeder, the driving force transmission path, etc. are different, the operation of the present invention will not change.

[Effects of the Invention] In summary, the present invention provides the following excellent effects.

hoppers provided in multiple stages in the traction direction, a large number of feeding ports provided in the bottom of these hoppers in the machine width direction and aligned in the traction direction, and feeding means for selectively opening the feeding ports in the traction direction.
