Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a device for preventing clogging of a fertilizer discharge section in a fertilizer applicator that applies fertilizer to rice fields.

[Conventional technology]

Conventionally, in a fertilizer dispensing machine configured by connecting the lower end of a fertilization hose extending from a fertilizer delivery section to the upper part of a fertilization gutter integrally formed at the rear of a groove-cutting body, waterproofing of the upper part of the fertilization gutter has been used. The structure was difficult to prevent mud and easily clogged with fertilizer, it was difficult to connect the bottom end of the fertilizer hose, and it was difficult to insulate the sensor when installing a sensor to detect clogging.

[Problem that the invention attempts to solve]

The present invention solves these problems by properly waterproofing and mud-proofing the upper part of the fertilizer gutter to prevent fertilizer from clogging, and by positioning the lower end of the fertilizer hose reliably. In addition to being able to be connected, a clogging sensor can be mounted with good insulation, and these mechanisms can be installed and removed easily and suitably.

[Means for solving problems]

Therefore, in the present invention, a rubber cap that can cover the upper part of the fertilizing gutter is removably fitted to the upper part of the fertilizing gutter, and the lower end of the fertilizing hose can be press-fitted into the cap. The hole and
A hole portion into which a clogging sensor can be press-fitted is formed.

[Effect]

With this configuration, the upper part of the fertilizing gutter can be made waterproof and mud-proof by fitting the cap to prevent fertilizer from clogging, and the lower end of the fertilizing hose and the clogging sensor can be well press-fitted into each hole of the cap. It can be installed well by fitting and positioning,
The rubber cap can be easily attached and removed by pulling it.

〔Example〕

Next, the embodiment shown in the drawings will be described.

Figure 2 shows a side view of the passenger rice transplanter.
The planting portion D is connected to the rear of the vehicle via a link mechanism 7, and the passenger vehicle C has both front wheels 8 and both rear wheels 9.
A handle 11 is installed at the rear of the front bonnet 10, a seat 17 is installed at the upper center of the rear cover 12, and three seats are provided on both sides of the bonnet 10 in the vertical direction.
The planting section D has a plurality of floats 14 arranged in parallel at the bottom and a seedling platform having a plurality of seedling mounting surfaces above the floats 14. The stand 15 is installed obliquely so as to be able to freely reciprocate in the horizontal direction, and a plurality of planting claws 16 are shown below the seedling stand 15, and the float 14 is raised while scraping block seedlings.
It is constructed in the same way as the conventional structure by installing it so that it is planted on the side of the tree.

A support rod 18 for supporting from the planting portion D is installed horizontally above the rear part of the planting portion D, and each fertilizer hopper a, each having an opening/closing lid 19 on its upper part, is supported and constructed by the support rod 18, Fertilizer hoses 3, 3 are hung from the fertilizer delivery parts A, A connected to the lower part of each fertilizer hopper a, and grooves are made in the field on the side of the float 14, which is the lateral lower part of each planting claw 16. The groove-forming bodies 1 that can be used are each supported by brackets 20 and installed, and at the rear of each groove-forming body 1 there is a fertilization gutter 2 with a U-shaped cross section that is open in the vertical direction and the rear.
are arranged in series to form the same structure as the conventional structure.

A hole 21 is formed in the upper front surface of the fertilization gutter 2, and notched recesses 22, 22 are formed in both rear sides, and the hole 21 is formed in the lower front surface of the rubber cap B that can be fitted onto the upper part of the fertilization gutter 2. A protrusion 23 that can be fitted into the cap 21 is formed protrudingly, and a protrusion 24 that can be fitted into the notch recesses 22 and 22 is protrusively formed on the inside of the rear part. A vertical hole 4 into which the lower end opening 3a can be press-fitted is formed, and a vertical hole 6 into which a clogging sensor 5 can be press-fitted is formed behind the hole 4.

Both ends of the support rod 18 are connected to the lower parts of both support rods 25, 25 whose upper parts are highly inclined backwards, and both ends of the sheet 26 facing upward of each fertilizer hopper a, a are connected with both support rods. Cylindrical portions 26a, 26a that can be fitted onto the upper portions of 25, 25 are integrally formed.

Vertical support cylinders 27 are fixed to the side ends of the rear cover 12 of the passenger car C using fixtures 28, and the lower part of an L-shaped support rod 29 is rotatably and lockably fitted into the support cylinder 27. At the same time, a rotatable and lockable support stand 30 connected to the upper end of the support rod 29 is installed so that a fertilizer bag 31 can be attached thereto. It is installed and configured so that the position can be changed from above the preliminary loading table 13 to above the fertilizer tank a.

Therefore, the protrusion 23 of the cap B is fitted into the hole 21, and the protrusion 24 is inserted into the notched recesses 22, 22.
When engaged, the cap B can be pulled and fitted to cover the upper part of the fertilization gutter 2,
The fertilizer hose 3 can be attached by press-fitting the lower end port 3a into the hole 4 and the clogging sensor 5 into the hole 6.
The upper part of the fertilizing gutter 2 that discharges fertilizer can be covered with the cap B in a waterproof and mud-proof state, and the clogging sensor 5 can also be installed in an insulated state.

In addition, when removing the cap, it can be removed by pulling out the fertilizing hose 3 and the clogging sensor 5 from the cap B.
2 and remove the protrusion 23 from the hole 21, the cap B can be removed.

Moreover, the upper part of each fertilizer hopper a can be covered with a sheet 26, so that even when the vehicle is lowered, fertilizer can be replenished by opening the opening/closing lid 19 as shown by the imaginary line in FIG. 2.

On the passenger car C, as shown in Fig. 2, the fertilizer bag 31 is mounted on the upper side of the front part of the car body so that the car can be driven while keeping the balance of the car body.When replenishing the fertilizer hopper a, As shown by the imaginary line in FIG. 2, by rotating the support rod 29 rearward, the fertilizer bag 31 can be moved to the upper side of the fertilizer hopper a, so that it can be easily replenished.

[Effect of idea]

In this way, the present invention can cover the upper part of the fertilizing gutter 2 with the rubber cap B to provide good waterproofing and mud-proofing to prevent fertilizer from clogging, and the lower end port 3a of the fertilizing hose 3. The part can be well positioned and connected to the cap B, and the clogging sensor 5 can be mounted with good insulation, and the cap B can be fitted so as to be pulled, and the fertilization hose 3 and the clogging sensor 5 can be press-fitted. It has the advantage that it can be easily installed by fitting and can be easily removed, and that it can be easily implemented with a simple structure.
