Description

[Detailed description of the invention] This invention involves attaching a fertilizing tool that cuts a trench in a field and supplies fertilizer to the trench formed on a grounding float so that it is in contact with the rear-facing end of the soil leveling section of the float where seedlings are planted. The present invention relates to a rice transplanter with a fertilization device configured so that the fertilization position can be brought close to the seedling planting position.

Conventionally, in the rice transplanter described above, the depth of fertilization cannot be changed, and the timing at which fertilizer is absorbed after seedling planting cannot be adjusted. In addition, if there is foreign matter such as straw waste scattered in the field, the foreign matter will remain caught on the downward protrusion from the ground float of the fertilizer applicator as the machine travels, and this caught material will cause the wide groove to become clogged. Problems such as formation of muddy soil, which leads to poor backfilling after fertilization, and muddy soil being washed away, which leads to the lodging of already planted seedlings, tend to occur.

The purpose of the present invention is to make it possible to change the depth of fertilization and to prevent the above-mentioned troubles from occurring even when fertilization is applied to any depth in a field where foreign matter is scattered.

A characteristic configuration of the present invention is that, in the above-mentioned rice transplanter with a fertilizing device, the forward-facing outer wall surface of the fertilizing tool is formed into an inclined surface located toward the rear of the machine body toward the lower end,
The attachment height adjustment part of the fertilizer application tool is provided in such a manner that the fertilizer application tool can be slid in the direction of inclination of the front outer wall surface, and its functions and effects are as follows.

That is, by providing the adjustment section, the length of the downward protrusion of the fertilizer applicator from the ground float can be changed by its action. Therefore, it is possible to adjust the depth of fertilizer application, and fertilizer can be supplied near the planted seedlings so that it is absorbed immediately after planting, or it can be supplied deep away from the planted seedlings so that the fertilizer can be absorbed quickly after planting. This makes it convenient to adjust the timing of fertilizer absorption as needed, such as allowing it to be absorbed after the fertilizer has grown. Furthermore, by making the forward facing outer wall surface the inclined surface, even if foreign matter gets caught in the fertilizer application tool, it will automatically come off to the bottom of the fertilizer application tool as the aircraft travels due to the action of the slope. As in the case of providing a foreign matter removal tool which has a vertical surface and has a downwardly inclined surface similar to the above-mentioned inclined surface to sink foreign matter located in front of the fertilizer application tool, a special foreign matter removal tool is provided. Not only do they not use a foreign matter removal tool, but when the fertilization depth is increased, the fertilization tool protrudes below the anti-snapping device and foreign matter removal cannot be carried out, or when the fertilization depth is shallowed, the fertilization tool is not used. A groove is also formed under the groove formed by the groove for the dirt removal tool, and there is no problem such as inconveniences such as fertilizer getting into the groove. Therefore, no matter what depth the fertilizer is applied to, it is possible to prevent impurities from getting caught in the fertilizer application tool and accumulating, and also to avoid the problem of the fertilization depth changing unevenly as described above.
While ensuring that the fertilization depth is at a predetermined depth and simplifying the structure, it is possible to reliably avoid problems such as poor backfilling of trenches and falling of already planted seedlings caused by foreign matter. Furthermore, by sliding the fertilizer applicator in the above-mentioned inclination direction, a gap is created between the grounding float and the fertilizer applicator due to the change in installation height, as is the case when changing the position in the vertical direction, and mud can become clogged. This can prevent mud from accumulating. Therefore, even though the forward facing outer wall surface is a sloped surface, it is possible to prevent mud from accumulating at the attachment part of the fertilizer application tool regardless of the change in the fertilization depth, and to prevent poor ground leveling and mud pushing caused by accumulated mud. did it.

Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, each of a plurality of seedling planting arms 1 arranged in parallel in the lateral direction of the machine is connected to a transmission case 3 which is provided so as to be driven and swung up and down via a link mechanism 2. A seedling tray 4 for feeding seedlings is attached to each seedling planting arm 1 so as to be driven back and forth from side to side in conjunction with the seedling planting movement of the seedling planting arm 1, and a plurality of seedling stands 4 are arranged in parallel in the lateral direction of the machine. A grounding float 5 is mounted so that its mounting height can be freely adjusted via an arm 6 that can be vertically swung and fixedly operated. Then, the fertilizer tank 7 is attached to a support base 9 extending from the transmission case 1 via a plurality of fertilizer dispensing devices 8 for taking out fertilizer from the tank 7, and each fertilizer dispensing device 8 is rotated to feed out the fertilizer. The body 8a is connected to the link mechanism 2 via the link 10.
A plurality of fertilizers are configured to be driven in conjunction with the seedling planting movement of the seedling planting arm 1, and are connected to the feeding device 8 via hoses 11 so as to be supplied with fertilizer separately. Ingredients 12...
For configuring a rice transplanter with a fertilization device by attaching them to the grounding float 5 in a state where they are arranged near the front of each of the seedling planting arms 1 and interlockingly connecting them to the traveling body, and A seedling planting device with a fertilizing device is configured in which each of the fertilizing tools 12 creates a trench in the field and supplies fertilizer to the formed trench as the machine travels.

To configure the connection structure between the fertilizer tank 7 and the feeding device 8, as shown in FIG. The protrusion 13 integrally formed on the feeding cylinder part 8b is inserted into the hole of the tank cylinder part 7a.
It is designed to engage and prevent the tank 7 and feeding device 8 from coming off. In order to connect and separate the tank 7 and the feeding device 8, the tank cylindrical portion 7a is placed in a state in which the wall with the hole bulges outward, and the feeding cylindrical portion 8b is placed in a state where the wall with the hole is bulged outward, as shown by the imaginary line, and the feeding cylindrical portion 8b is inserted into the protrusion 13. By deforming the walls of the cylinders so that they bulge inward, both cylinder parts 7a and 8b can be inserted and removed.

As shown in FIGS. 2 and 3, each of the fertilizer applicators 12 is composed of a bend-formed sheet metal groove 12a and a fertilizer supply cylinder 12b inserted and attached to the groove 12a. , is formed in a shape having a downwardly inclined forward facing outer wall surface 12c located toward the rear of the aircraft body toward the lower end, and a rearward facing end surface 5 of the seedling planting area soil leveling part 5a of the grounding float 5.
