Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a medium cultivation soil having a fertilization function capable of performing a fertilization operation simultaneously with a medium cultivation soil operation performed when cultivating a plant such as soybean. It relates to a working machine.

[Problems to be Solved by the Related Art and the Invention] Generally, as in the case of cultivating soybeans or the like, in order to cover secondary roots generated from stalks or the like during the growth, middle cultivation and cultivation are carried out. Some require ridges. Therefore, there is known a medium cultivation cultivation work machine provided with a medium cultivation part using members such as a coulter and a cultivation part for cultivating remaining medium cultivation soil to ridge the vegetation part. Since it is a machine, it is not possible to perform fertilization work, and there is a drawback in that when it is necessary to perform additional fertilization there, it is necessary to perform additional fertilization using a separate fertilizer work machine.

On the other hand, as shown in Japanese Utility Model Publication No. 51-10095, there is a type in which fertilizer applied to the base of a crop is cultivated and covered, but in this case, ridges and fertilizer coating are applied in a single cultivation. Because it is done at the same time, if the cultivation action is absolutely impossible, if you try to ridge the required height,
Due to the large amount of soil cultivated, the fertilizer flows to the crop side and reaches the root, and as a result, plants suffer from burning of fertilizer, causing poor growth and, in severe cases, becoming depleted. Yes.

Means for Solving the Problems In view of the above-mentioned circumstances, the present invention has been created with the object of providing a medium cultivation soil cultivator having a fertilizer application function capable of eliminating these disadvantages. A fertilizing means for applying fertilizer between the vegetation crop strips, a covering medium tillage means for cultivating the soil between the furrows and lining up the vegetation crops in a state of covering the fertilized fertilizer, and furrowing; And a cover cultivation means for cultivating the remaining soil of the soil, covering the middle cultivated soil portion brought to the vegetation crop strip, and raising the ridge.

According to the present invention, the fertilizer application can be performed simultaneously with the medium cultivation soil cultivation work by using this configuration, but at this time, the fertilizer is caused to flow to the root part by the momentum of the cultivation soil. However, it is possible to cover and fertilize a desired portion without fail.

Example Next, an example of the present invention will be described with reference to the drawings.
In the drawings, reference numeral 1 denotes a traveling body used for a riding type fertilizer planting machine, which is an example of a paddy traveling vehicle.

In the hitch receiving portion 6, left and right support plates 6b are connected via a pipe material 6c so as to sandwich the top link 3a from both sides, and the support plate 6b is formed with a locking groove 6d. Then, when the top link 3a is fitted between the support plates 6b and the support shaft 4a is applied to the entrance of the locking groove 6d, the lifting link mechanism 3 is raised to lift the working unit 2, and the support shaft 4a Is fitted deeply into the locking groove 6d, and the support rod 4b contacts the lower surface of the support plate 6b for positioning, and the hitch pin 8 is moved from one side of the bracket 4 to the other side through the hitch receiving portion 6. The work unit 2 is configured so that it can be easily attached to the traveling machine body 1 by preventing the work unit 2 from being removed after the penetration.

Reference numeral 9 denotes a substantially L-shaped work unit bracket fixed to the left and right ends and the center of the toolbar 5 so as to be movable in the left and right directions. A mounting bracket 10a for the gauge wheel 10 is fixed integrally, and at the front end thereof,
An adjusting rod 10b on which a gauge wheel 10 is journaled is supported at the lower end so as to be vertically adjustable. 10c is a scraper for a gauge wheel.

Numeral 11 denotes a fertilizing nozzle, and a bracket 11a protruding from a base end of the fertilizing nozzle 11 is horizontally moved from a support tool 11b which is fixedly fastened to a mounting position of the gauge wheel bracket 10a in the working unit bracket 9. Support rod 1 protruding toward
It is pivotally fixed to 1c so as to be freely rotatable, so that the position of the nozzle end can be adjusted as described later. The fertilizer application nozzle 11 has a fertilizer tank 12 mounted on the traveling machine 1
The fertilizer therein is connected to a fertilizer pipe 14 which is fed by the drive of a fertilizer pump 13 via a joint member so that the fertilizer in the form of paste can be fertilized continuously or intermittently as required.

Coal brackets 15 are integrally mounted below the corners of the work unit brackets 9 so as to be substantially aligned with each other, but the brackets 15 project forward so as to form a generally triangular shape. Is formed. In each of these brackets 15, the left first plate 15 and the central second bracket 15 all have the left plate 15a protruding forward long, and the right third bracket 15 has the left plate 15a forward. It is configured to protrude long. A pair of left and right coulters 16 are freely rotatably mounted on the respective plate members 15a and 15b via a support shaft 16a so as to extend rearward. The coulter 16 mounted on the 15a or 15b is disposed so as to have a positional relationship shifted forward (forward) with respect to the coulter 16 mounted on the short plate 15a or 15b which is not so, so that the coulter 16 of the following coulter 16 is disposed. The leading end is inserted into the rear side of the leading end of the preceding coulter 16 so as to minimize the occurrence of the tillage. The fertilizing nozzle 11 described above is arranged so that the rear end of the fertilizing port is pivotally adjusted so that the distance from the preceding coulter 16 is substantially equal, and the fertilizing position is on the soil where the coulter 16 reverses the middle fertilization. The fertilizer applied in this way is configured such that the primary cover is formed on the medium-tiled soil in a state where it is brought to the crop side.

In addition, at the rear end of the work bracket 9,
17 is supported swingably via a support shaft 17a. A cultivation plate 18 is integrally fixed to a lower end portion of the cultivation bracket 17, and an earthing bracket 19a is integrally fixed thereto. The mulch bracket 19a is provided with a long hole-shaped adjusting portion 19c in which a link 19b protruding from the back of the mulch plate 19 is fixed so as to be adjustable back and forth, so that the angle of the left and right mulch plates 19 can be adjusted. ing. And
The middle cultivation residual soil by the coulter 16 is cultivated and further covered with the soil on the middle cultivated soil brought to the crop side, and a secondary covering is performed, and a ridge of a required height is provided. An adjuster 17b for adjusting the angle of the cultivation bracket 17 is provided between the upper end portion of the cultivation bracket 17 and the working unit bracket 9.

In the embodiment of the present invention configured as described above, this is a medium tilling by a coulter 16,
By the cultivation action of 19, the soil between the ridges of the crop can be cultivated in the middle cultivation and the ridges of the required height can be laid.

In other words, the fertilizer is applied from the fertilizer nozzle 11 to the furrow in accordance with the running of the aircraft, and the fertilizer is first covered with the soil cultivated in the middle tillage by the coulter 16 to the crop side, and the fertilizer is covered by the soil. The first ridge is made.
Next, the middle cultivated soil in the furrow is cultivated and covered so that the fertilizer-covered portion is further raised by the action of the breeding plate 18 and the burrowing plate 19, and a secondary ridge is provided at the base of the crop. do.

As described above, in the practice of the present invention, the fertilizer is applied simultaneously with the medium cultivation soil. At this time, the first cover ridge is formed by the medium cultivation soil, and then the fertilizer is applied by the medium cultivation soil. Then, the second covering ridge is formed, and a stepwise ridge is formed.Therefore, a large amount of soil flows to the crop side as in the case where the ridge of the required height is used once. Thus, it is possible to prevent a problem that the fertilizer is flowed to the root part, and to apply fertilizer to a desired position separated from the root part at an appropriate interval. As a result, of course, it is possible to prevent the runoff of fertilizer, but it is also possible to prevent the occurrence of problems such as burning of the fertilizer due to the location of the fertilizer being too close. Can be tied.

In addition, in this method, the fertilizer application part is consciously brought to the crop side when performing medium cultivation soil, and as a result, the initial fertilizer application position can be separated from the crop. The disadvantage that the fertilizer can sometimes be prevented from being directly applied to the leaf stem portion can be avoided, and after medium cultivation, the fertilizer can be brought to a desired position to obtain an excellent fertilizing effect, which is convenient.

In addition, the fertilizer application from the fertilizer nozzle 11 is also shifted in front of the coulter 16, but the fertilizer can be moved in the same state on both the left and right. In addition, since the fertilizer application consideration only needs to be adjusted by swinging the fertilizer nozzle 11, there is an advantage that the adjustment is simple and there is no need to prepare two types of fertilizer nozzles.

It should be noted that the present invention is not limited to the above-described embodiment, and the fertilizer is not limited to a paste (liquid) type, and various types of fertilizers such as granules or powders may be used. Needless to say, it can be implemented. However, in this case, it is needless to say that a fertilizer corresponding to the form of the fertilizer is used. Further, the fertilizer application section may be one which is not brought to the crop side in the middle cultivation soil as in the above embodiment.

[Effects] In summary, since the present invention is constructed as described above, it is possible to lay the vegetation crop strip by means of medium cultivation soil, and at the same time, to fertilize the ridge section. In the fertilizer, a first gentle furrow is formed by the medium cultivated soil brought to the vegetation crop, and then a second furrow is furnished by the cultivated soil.

As a result, the fertilizer applied in the previous process is prevented from being disturbed due to the flow of a large amount of soil into the vegetation crop strip side, as in the case of covering ridges at once with only cultivated soil. As a result, it is possible to improve the fertilizer effect by allowing the portion furnished at the required height to be well covered with fertilizer, thereby increasing the yield.
