Description

[Detailed Description of the Invention] The present invention relates to a soil plate adjustment device.

Conventionally, there was a device that adjusted the amount of soil by adjusting the amount of soil protruding from the soil plate, but it was not possible to catch foreign objects such as straw or grass on the soil plate and drag them down, or to remove stones or hard lumps of soil. There was a problem that if the soil plate hit the soil plate, the soil plate would be damaged and the soil plate would not work properly.

Therefore, in order to solve the above-mentioned problems, the present invention is equipped with a trenching body at the rear of the float, and a cultivating soil plate is installed at the rear of the trenching body and at the side end of the float. A soil plate is provided to be rotatable around a vertical axis with respect to a float whose front end is pivoted so as to be vertically movable, and an elastic body is provided to move the soil plate in the direction of rotation in which the amount of protrusion from the float increases. The structure is configured so that the amount of protrusion of the soil plate from the float can be adjusted by the pulling force of a wire that resists the urging force and is linked to the vertical movement of the front end of the float.

Next, the embodiment shown in the drawings will be described. Fig. 1 shows a side view of a rice transplanter with a fertilizer applicator, in which wheels 1 are mounted on the tips of two swing-type transmission cases 6 that extend rearward on both sides of the rear side of the engine E, and the rear planting case Both handle rods 8 are extended rearward and upper from the rear of the handle rods 8, 8, so that the lower part of a seedling stand 9 provided diagonally in front of the handle rods 8, 8 approaches the seedling take-out plate 10 and reciprocates in the lateral direction. This machine A is constructed in the same manner as the conventional structure by installing the planting claws 11 on the seedling take-out plate 10 so as to scrape the block seedlings and plant them on the rice field.

Still, pantograph-type bending connecting rods C, C are interposed between the front upper surface of the float B, which extends in the longitudinal direction along the lower part of the machine A, and the lower surface of the engine E, and the rear part of the float B is installed. A planting depth adjustment lever 12 is interposed between this and the planting case 7 of this machine A above it, and both planting claws 11 approach the inside of the planting position where block seedlings are to be planted. Grooving and fertilizing bodies 2, 2 are fixedly installed on both sides of the rear part of the float B, respectively, and are capable of making grooves on the rice field and applying fertilizer into the grooves through the rear part. Both hoses 24 hanging down from the feeding part 14 at the lower part of the fertilizer tank 13 are connected to the rear upper part of the both cultivation ditch and fertilizer application body 2, and are constructed in the same manner as the conventional structure.

On the rear side of the both cultivation ditch and fertilization body 2, there are provided both cultivation soil plates 3, which use the fertilization body to push mud into the grooves to be cultivated, but the cross section is bent. Both of the growing soil plates 3, which are becoming longer, are placed on the lower surface of the float B so that the plane is inclined in the front-rear direction, and the lower ends of the two culture soil plates 3 are vertically fixed to the front ends of the supporting shafts 15, which are integrally welded to the float B.
The upper part of the support shaft 15 above the float B is provided with connecting pins 16 and 17 protruding toward opposite sides, and the support pin 18 fixed to the front side of the support shaft 15 and A tension spring 19 is connected between the connecting pin 16 and the end of the wire 4 extending from a wire receiver 20 fixed to the upper surface of the float B on the front side of the support shaft 15 is connected to the connecting pin 17. , the tip of the wire 4 extending forward from the wire receiver 21 at the rear of the bending connection rod C is connected to the pin 22 in the middle of the bending connection rod C, and when the bending connection rod C is in an extended state, the wire 4 The wire 4 is installed and configured so that when the wire 4 is relaxed and bent, the wire 4 is pulled forward.

In addition, in the figure, 23 indicates a groove made by the groove-making and fertilizing body 2.

Therefore, when the wire 4 is pulled forward or loosened, the tension spring 19 is stretched or pulled again, and the support shaft 15 rotates, and the soil plate 3 is rotated around the support shaft 15. It will rotate as shown by the arrow A, and depending on the state of the rotation, the amount of mud pushed toward the groove 23 by the soil plate 3 as shown by the arrow B will be adjusted.

During work, in a hard field, the machine A stands up and the bent connecting rod C stretches as shown in FIG. axis 1
5, the soil plate 3 rotates outward as shown by arrow C, and the hard mud is sufficiently pushed onto the groove 23 by the soil plate 3.

In addition, if the field is soft, the bending connecting rod C will bend as shown in FIGS. 1 and 2, and the wire 4 will expand into the tension spring 19 and be pulled forward. The soil plate 3 rotates slightly toward the lower surface of the float B and becomes retracted.
Therefore, the soft mud is sufficiently pushed onto the grooves 23 by the soil plate 3.

As described above, the present invention has a structure in which a trenching body is installed at the rear of the float, and a soil plate for raising soil is installed behind the trenching body and at the side end of the float, and the front end can be moved up and down. A soil plate is provided to be rotatable around a vertical axis with respect to a freely pivoted float, and the soil plate is biased by an elastic body in the direction of rotation in which the amount of protrusion from the float increases, and the biasing force is The structure is designed to adjust the amount of soil protruding from the float by applying a pulling force to a wire linked to the vertical movement of the front end of the float, so it is possible to adjust the amount of soil to suit the hardness and softness of the field. It is.
