Description

[Detailed description of the invention] [Industrial field of application] This invention has a sliding contact rod that is fixed to the outer tube and that can protrude to the side of the metering case and is connected to a storage tank that is integral with the outer tube. It fits into the holding pipe that is integrated with the mounting pipe so that it can move forward and backward, and by adjusting the setting position of the sliding rod on the holding pipe, it is possible to select the position where the fertilizer falls onto the partition plate in the groove cutting plate. , a horizontal adjustment rod assembled to a grounding groove plate pivotally attached to the lower end of the mounting tube fixed to the outer tube is attached to the side of the metering case by adjusting its setting position with respect to the mounting tube; This invention relates to a deep layer fertilizer machine that can adjust and maintain a metering wheel at a constant depth in the soil at all times.

[Conventional technology]

Conventionally, existing deep layer fertilizer machines have a metering wheel 2 integrally coaxial with a metering rotor (not shown) housed in a metering case 1, as shown in FIG. 8, for example.
is assembled, and this metering wheel 2 follows and travels as the running wheel 3 advances, and as the metering rotor rotates due to this traveling, the fertilizer from the storage tank 4 passes through the metering rotor and reaches the groove cutting plate. It is possible to fall into the soil from a partition plate 6 which is interposed and held between 5 and 5. As the groove cutting plate 5 advances, soil adheres to and accumulates in the opening 7 of the groove cutting plate 5, preventing the fertilizer from falling into the soil.
A pusher 9, which rotates when the traction tool 8 is pulled up, scrapes off the mud 10 and applies fertilizer.

[The problem that the idea aims to solve]

In the case of the above-mentioned deep layer fertilizer machine, the metering wheel 2 may float or sink slightly in the soil due to dryness, wetness, unevenness, or other conditions on the ground surface, and maintains a constant position in the soil. However, it is impossible to drive, and the groove cutting plate 5, storage tank 4, etc., which are integrally assembled with the above, also move up and down, so fertilizer is constantly deposited into the soil at a constant depth. It is extremely difficult for the fertilizer to fall into the soil, and as a result, the fertilizer is buried vertically in the soil in a disorderly manner, and it is hard to escape the feeling that it is still lacking in its ability to function as a deep layer fertilizer machine.
In addition, from the point of view of mud adhering to the groove cutting plate 5, the traction tool 8,
Since it is necessary to separately install the presser 9, etc., there is a drawback that it is difficult for the operator to avoid the feeling of complication during fertilization work.

This idea was proposed by focusing on the above-mentioned drawbacks, and its purpose was to maintain and run the metering wheel in a constant position at all times, regardless of the elevation of the ground-grooving groove plate, and to spread fertilizer to the ground. The present invention aims to provide a deep layer topdressing machine that allows soil to be dropped to a certain depth inside the groove, prevents soil excavated by a groove cutting plate from floating and scattering, and also prevents soil from adhering to the groove cutting plate. .

[Means to solve the problem]

In order to achieve the above-mentioned purpose, the deep layer fertilizer machine of this invention has a storage tank fixed to the handle formed integrally with the outer pipe, and a regulating wheel rotated by a metering wheel connected to the storage tank via a guide pipe. A metering case with a metering rotor installed therein is connected, and a sliding contact rod protruding from the metering case is removably attached to a holding tube that is integral with the mounting tube fixed to the outer tube. A partition plate is held between groove plates fixed and suspended from a grounding groove plate pivotally attached to the lower end of the mounting pipe, and a pressing piece formed at the tip of the partition plate is made to protrude from the opening of the groove plate. , one side of the horizontal adjustment rod is connected to the tip of the grounding groove plate, and the other side of the horizontal adjustment rod is loosely connected to a support plate whose setting position on the mounting pipe can be adjusted.

In the figure, 54 is a mounting rod for the trench covering soil board 51.

[Effect]

Since this device has the above-mentioned configuration, when fertilizing, the running wheel 20 rotates when the engine E is started, and the groove cutting plate 48 sinks into the soil by contacting and moving the ground groove plate 39 to the soil surface. into the metering wheel 27
rotates while being inserted into the soil at a certain depth, and along with this rotation, the rotating shaft 26 and metering rotor 28, which are integrally assembled with the metering wheel 27, also rotate at the same time.
The fertilizer K in the storage tank T is transferred to the guide pipe 22, the connecting pipe 55,
It falls through the suction port 23, metering rotor 28, discharge port 24, and discharge pipe 25 to the partition plate 49 interposed between the groove plates 48, and is fertilized below the ground surface.
Therefore, due to the unevenness of the soil surface, the grounding groove plate 39 swings up and down using the fitting pipe 37 at the lower end of the mounting pipe U as a fulcrum, but it does not move integrally with the handle 17 held by the operator (not shown). The sliding contact rod on the metering case B side is attached to the assembled holding tube 36 on the mounting tube U side.
is fitted and held in a predetermined position, so that the metering wheel 2 rotatably attached to the side of this metering case B
Since fertilizer 7 is also always held at a constant position, the fertilizer K that falls through the metering rotor 28 that rotates integrally with the metering wheel 27 is also always buried at a constant depth.

In addition, when applying this fertilizer, the metering switch Z itself is moved back and forth as appropriate along the longitudinal direction of the groove a of the metering rotor 28, the opening area of the groove a to the suction port 23 is adjusted and set as appropriate, and then By abutting and holding the tip of the stopper piece 35 against the inner cylinder part of the metering switch Z, the predetermined amount of fertilizer can be easily regulated, and the discharge pipe 25
Since the diffusion prevention piece 47 faces downward, the fertilizer K from the discharge port 24 is reliably dropped into the soil, and the soil excavated and removed by the groove cutting plate 48 is cut into grooves by the pressing piece 50. While suppressing soil from entering through the opening m of the cut plate 48 toward the partition plate 49, the groove portion to which the fertilizer has been applied is covered with soil by the movement of the groove cover soil plate 51. In addition, the pressing piece 50 can prevent the soil from rising unnecessarily, thereby preventing the fertilizer from rising to the soil surface.

When the fertilizer to be applied is dry,
The fertilizer K easily passes through the partition plate 49 and falls into the soil, but when it becomes moist, the fertilizer K sticks to the middle of the partition plate 49, making it impossible to apply the desired amount of fertilizer. Since it is necessary to expose the discharge pipe 25 to the bottom of the partition plate 49 as much as possible, the operator moves the slide contact rod along the holding pipe 36 to the soil cover plate 51 side and connects the discharge pipe to the lower end of the partition plate 49. 25 so that their lower ends are close to each other. Note that when changing the depth of the metering wheel 27 from the ground surface depending on the soil surface condition, after adjusting the setting position of the upper end of the horizontal adjustment rod 44 on the support plate 43,
By screwing and tightening the adjustment nut 46 onto the male screw S, the metering wheel 27 can be set to a desired constant position by adjusting the set positions of the sliding rod 1, the holding tube 36, and the opening/closing casing 29. Therefore, the fertilizer K can be dropped and buried at a desired constant depth at all times.

〔effect〕

According to this invention, a metering case equipped with a metering wheel is connected via a flexible guide tube to the lower end of a storage tank fixed to a handle integrated with an outer tube that covers the transmission shaft. A sliding rod that protrudes to the side of the case is attached to the holding tube that is integrated with the mounting tube fixed to the outer tube so that it can move forward and backward, so the metering case can be moved toward the holding tube side depending on the degree of dryness and humidity of the fertilizer. By moving the fertilizer forward and backward, the fertilizer from the storage tank can always fall onto the partition plate, allowing it to fall and bury into the soil to a certain depth. In addition, the lower part of the horizontal adjustment rod is attached to the grounding groove plate pivotally connected to the mounting pipe, and the upper part of the horizontal adjustment rod is attached to the mounting plate attached to the mounting pipe so that its setting position can be adjusted. Although the ground groove plate swings up and down using the bottom end of the installation pipe as a fulcrum due to the unevenness of the ground surface,
The mounting pipe, holding pipe, and metering case, which are assembled with the upper part of the horizontal adjustment rod loosely aligned, always maintain a preset position relative to the ground surface, so the metering wheel also always maintains a constant position. Since it rotates while being held, it is possible to excavate the soil to a constant depth, and the fertilizer can be dropped to a specified depth, eliminating the risk of so-called "uneven fertilization." Conventionally, in this type of topdressing machine, the metering wheel moves up and down due to irregularities in the ground surface, which can correct the problem of fertilizer falling vertically and randomly into the soil. The groove plate is pivotally attached to the lower end of the mounting pipe, and the upper part of the horizontal adjustment rod is loosely connected to the mounting pipe, so it will not receive local loads from vibrations, shocks, etc. when the vehicle is running. There is no risk of accidents such as breakage or destruction, and the setting position of the metering wheel can be easily adjusted depending on the land situation via the horizontal adjustment rod, making it easy to handle and eliminating the need for unnecessary adjustment mechanisms. Since there is no risk of complicating the partitioning, it can be produced robustly and inexpensively, and since the pressing piece is slightly protruded outward from the lower end of the opening of the groove plate, it is possible to prevent mud from entering the partition plate. It also prevents soil from adhering to the trench cutting board, so it has practical benefits such as eliminating the need for a mud scraping tool.
