Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a fertilizer spreading device for a fertilizer applicator that spreads fertilizer into soil.

0002

[Conventional technology]

Conventionally, as a fertilizer applicator for dispersing into the soil, there is a method described in Japanese Utility Model Application Publication No. 58-41133. There is a disclosure that connects the fertilizer guide tube of the fertilizer applicator with the tractor and rotary tiller. The fertilizer is placed between the fertilizer guide tube and the fertilizer is spread from the bottom end of the tube to the ground surface. The fertilizer is stirred and mixed by the tilling section of the rotary tiller.

0003

[Problem that the idea aims to solve]

However, once the fertilizer has been spread on the ground surface, it can be tilled using a rotary tiller. When mixing with the soil, the mixing may not be sufficient, especially if it is mixed deep into the soil. Have difficulty.

0004

[Means to solve the problem]

A rotary tiller is connected to the rear of the mobile agricultural machine, and a plurality of rotary tillers are connected to the mobile agricultural machine. A fertilizer applicator having a fertilizer guide tube is installed above the tilling section of the rotary tiller. A plurality of openings are formed in the rotary frame arranged along the tilling axis of the tilling section. The lower end of the fertilizer guide tube was connected to the opening.

[0005]

[Effect]

The fertilizer guided through the fertilizer guide tube is applied to the soil that is being tilled by the tiller. fall onto. This promotes the mixing of fertilizer and soil, and also allows the fertilizer to penetrate deep into the soil. Mixing is also carried out at. Furthermore, the type of tiller claws in the tiller and the rotation of the tiller By appropriately selecting the number of rotations, it is possible to achieve uniform mixing throughout the tilled layer. Partial mixing can be performed in which the mixed portion is formed into streaks.

[0006]

【Example】

An embodiment of the present invention will be described based on the drawings. After tractor 1, which is a mobile agricultural machine The rotary tiller is equipped with a top link 2 and a pair of left and right lower links 3. 4 are connected to each other, and there is also a lift that is moved up and down by a hydraulic device (not shown). The foot arm 5 and the lower link 3 are connected via a lift rod 6. . Further, a column 7 is erected at the rear of the tractor 1, and an upper portion of the column 7 is provided. There are a pair of left and right hoppers 8 and a plurality of fertilizer conduits 9 that guide the fertilizer in the hoppers 8. A fertilizer applicator 11 consisting of a plurality of fertilizer guide tubes 10 etc. connected to the lower end of the feed pipe 9 is installed. installed.

[0007] Next, each of the hoppers 8 is provided with three fertilization outlets 12, A fertilization port 13 is provided at the bottom of the hopper 8 at a position opposite to these fertilization discharge ports 12. It is formed. In addition, each hole is provided between the fertilizer application port 13 and the fertilizer application discharge port 12. Fertilizer amount adjustment that adjusts the amount of fertilizer applied by adjusting the opening degree of the fertilizer application port 13 for each flapper 8 A slider 15 connected to the moderator 14 and an opening that opens and closes all the fertilizer ports 13 at the same time. An interlocking shutter 17 connected to the closing operation section 16 and each fertilizer opening 13 can be opened and closed independently. An independent shutter 19 connected to an opening/closing operation section 18 is provided.

[0008] Next, the fertilizer conduit 9 is made of plastic resin, and the fertilizer conduit 9 is made of plastic resin. A reinforcing protrusion 20 is formed in a spiral shape on the outer circumferential surface of 9. Then, the fertilizer The upper end of the feed pipe 9 is fitted around the outer periphery of the fertilization outlet 12 and is connected to the band 21. is tightened and fixed, and the lower end of the fertilizer conduit 9 is connected to the upper end of the fertilizer guide tube 10. It is fitted onto the outside and is tightened and fixed by a band 22.

[0009] The rotary tiller 4 has a plurality of arms 23 fixedly protruding forward. The tractor 1 and the rotor are attached to the tips of these arms 23. Located between the tilling section 24 of the re-tillage device 4 and in the traveling direction of the tractor 1 A plurality of subsoilers 25 are arranged in the left and right direction orthogonal to the bolt 2 in an upright state. 6 and a nut (not shown). Note that the arm 23 and A plurality of holes for passing the bolts 26 are formed in the subsoiler 25. By selecting the hole through which the bolt 26 passes, the subsoiler 25 can be positioned in the vertical direction. The position is said to be adjustable.

0010 Next, the rotary tilling device 4 includes a rotary tiller located above the tilling section 24. A rotary frame 28 is provided parallel to the tilling shaft 27 of the tilling section 24. In this rotary frame 28, there are arranged in the left and right direction along the tilling shaft 27. A plurality of openings 29 are formed. Then, the fertilizer is applied to these openings 29. The lower end side of the guide cylinder 10 is inserted, and the upper end of this fertilizer guide cylinder 10 has the above-mentioned structure. The lower end of the fertilizer conduit 9 is connected to the sea urchin.

[0011] In such a configuration, the rotary tiller 4 is operated by driving the lift arm 5. While lowering the subsoiler 25, the lower end of the subsoiler 25 is inserted into the soil. Run Kuta 1. By rotating the tilling section 25, the tilling section 2 4, the soil is tilled, and the subsoiler 25 whose lower end is inserted into the soil is tilled. Helps the deep cultivation by the 24-year-old.

0012 Next, the fertilizer is applied by operating the fertilizer amount regulator 14 and the opening/closing operation parts 16 and 18. When the port 13 and the fertilizer discharge port 12 are communicated, the fertilizer in the hopper 8 is transferred to each fertilizer conduit 9. The fertilizer is distributed and falls, and this fertilizer further falls inside the fertilizer guide cylinder 10 and passes through the opening at the bottom end. It is distributed from Here, the spread fertilizer is being tilled by the tilling section 24. of the soil, promoting the mixing of fertilizer with the soil and increasing the amount of tilled soil. Sufficient mixing is performed even in the deep part.

[0013] In addition, regarding mixing of fertilizer and soil, the tilling claws used in the tilling section 24 By selecting the shape, the rotation speed of the tilling section 24, and the vehicle speed of the tractor 1, the tilling layer can be General mixing, which mixes the entire area uniformly, and partial mixing, which forms streaks in the mixed area. I can do it. In addition, use tilling claws that have a large soil stirring and moving action, or Overall mixing is achieved by increasing the rotation speed or slowing down the vehicle speed of tractor 1. On the other hand, using tilling claws with a small soil stirring or moving action, or rotating the tilling part. Partial mixing is performed by lowering the number or increasing the vehicle speed of tractor 1. .

[0014]

[Effect of the idea]

The present invention is a rotary tiller connected to the rear of a mobile agricultural machine as described above. A rotary frame placed above the tilling section has multiple openings along the tilling axis of the tilling section. form a section, and connect the lower end of the fertilizer guide tube of the fertilizer applicator attached to the mobile agricultural machine to the opening. As a result, the fertilizer guided inside the fertilizer guide cylinder is not tilled by the tilling section. This will cause the fertilizer to fall onto the soil that is in the process of being fertilized, promoting mixing of the fertilizer with the soil. It is possible to mix the soil thoroughly even in the deep part of the cultivated soil. In addition, the type of tiller claws in the tiller and the rotation speed of the tiller can be selected as appropriate. By doing this, it is possible to mix the entire tilled layer uniformly or to form a mixed part in a striped manner. It has the advantage of being able to perform partial mixing.
