Description

[Detailed Description of the Invention] Mokkomei quickly installed the grounding member in a downwardly biased state on a moving machine connected to the company's ground-lifting machine by a drive belt, and at the same time installed the grounding member at 10 aem. The detection result is within the set IQI J5ItJ
I am very impressed with Tada's machine, which has a control mechanism that is a masterpiece in the field of flight control.

Conventionally, in the above-mentioned ground tapping machine, in order to prevent the ground contact depth from changing due to changes in the hardness of the mud, when the mud is soft, W is used to prevent the grounding member from sinking into the mud. ! The downward biasing force of the grounding member is artificially adjusted to be more negative than when the soil is muddy, and when the muddy soil is hard, the grounding member climbs up on the muddy soil or straw waste and rises unevenly. In order to prevent the grounding member from collapsing, that is, to make the force of pushing down or sinking the lumpy mud or collected material greater than that when the muddy soil is soft, the lowering of the grounding member is required. The force t'' has been artificially adjusted to be stronger than it would be in the case of soft mud, and it has the disadvantage that it is difficult to operate properly.

The present invention has provided a structure that makes it possible to prevent changes in the mowing depth caused by changes in the filtration of mud without having to use a special 511% hand 111', and moreover, the configuration for this is simple and trouble-free. The aim is to make it difficult.

Next, one embodiment of the present invention will be explained based on illustrative drawings.

As shown in Fig. 1, a pair of left and right WIIJ grounding rods support the aircraft in cooperation with a traveling IkwJ wheel (2) having a rubber member ILI and a running wheel (2).
s+e 131. t-bi, t-sase, ka, z-shin (11) Installed on tlfJIs and behind it j!
! ! A seat (4) and a seat with a backrest (6j, etc.) are provided and are connected to the rear of the self-propelled Lingjing, and a seat (6) is connected from the self-propelled body to the Naeto attaching part (6). B)
It is configured to transmit rolling force, so that it is planted in 49.
There are 6 glossy passenger tago machines.

When the auxiliary free wheel (7) shown in Fig. 1 is running on the road, etc., the grounding needle +sr K * is lowered to lower fik,
This is for maintaining the aircraft body by cooperating with the wheels (2).

A hydraulic cylinder (81'frfi) is placed in front of the Wk base (3) for supporting the aircraft vertically at t°, and by operating this cylinder (8), the seedling S can be raised and lowered from the ground. be.

The lO arrangement dragon attached capital (6) is equipped with a pair of left and right side grounding flows (91)' = (9m) and - number of sensor grounding flows) (9b). mrJ period float (9m) = (9b) As shown in Figure 2, the link (Igm) is attached to bracket 4 so that it can be retracted up and down by a pivot, and the flow) (9m) - ( 9m)-
(9b) The rear link (t
gb) on the rear l1II side, consisting of
(2) and IIJ 1 @ @'s Tsukuda extension link 1a de U, it is attached to the elevation target for Miao Chen attached capital (6).

And, as shown in FIG. 2,
The aiFI operation part operation member for the control pulp similar to 'Up'! ! While applying the spring Q9 that biases the lowering position of the Ik base lever, interlocking the IiJ operating member and the fIJ bra bracket side link 2m) at the center 7o'L) (9b) with a wire, center flow) (9b) k MU is biased downward by the distribution spring αη, and the center float (
Based on the loss height detection in step 9b), the 7th leg 4 is automatically operated so that the detection result is within the set range.

In other words, if the height of the IIK attaching part of (center flow) (9b) is within the set range, the control loop (towards ) is held at the neutral position, and when the height of the part of the center 70-) (9b) that attaches to the seedlings exceeds the set range, the control pulp rotation is operated by the spring αη to a lower position of 11 m1. , "and", center flow) (9b)'s height is smaller than the set range, control pulp 4 is operated by center flow) (9b)'s irises to raise the grounding rod. As shown in Fig. 2 and Fig. 8, the center flow)
(9b), the locomotion support grounding member α- is attached so as to be able to swing up and down by the pivot shaft (■), and the IIQ rear side forward extension link mechanism (■) and the bracket side link (12 m) of this link mechanism are attached. The auxiliary grounding member (2) and f: The auxiliary grounding member j is moved into the body with respect to the center 70-) (9b) by the ridge-like movement from the interlocking push-pull lid (2). And they are interlocked and connected so that they move up and down in opposite directions.

When the (9b) tries to raise the seedling planting material, the auxiliary grounding member is pushed into the mud, and due to the thrust resistance of the auxiliary grounding member IIi into the mud. The center float (9b) is configured so that it has resistance against I, and the center 70-toe (9b) makes the mud hard.
Self-wJ's 4CI is the power of pushing down and sinking against immobility.
Then, even if there is a change in the depth of the tiller, 'ti planting capital (61 slud th1
The grounding needle 13) is automatically adjusted in the upper and lower fields so that the crows are within the set range, and #! Even if there are 6 changes in depth, the center flow (9b) is adjusted automatically so that the rising resistance of (9b,) is extremely large in muddy soil. This is so that you can work while plowing the fields.

In place of the separate d spring α71 and the operating wire, the center flow) <9b) is horizontally compared with a t-honorium with an N-shaped koji, etc., and based on the detection result, the control pulp convection driving sub-mechanism is activated. 11 relative units may be employed to operate these 1--j monument mechanisms, which are collectively referred to as the 1--j monument mechanism. The Schilling piece can be changed to a hydraulic or electric motor, and the earthing member 11J is a tapered piece attached to the rim (2), as shown in FIG.
2) was given a private inspection, and Rim (2) was given 91.

11 The backrest Ta2, as shown in FIGS. 5 and 6, is formed into a hook shape and then sealed with rubber, and attached to a support pipe. Also, it is reminiscent of the sudden wisdom @ to provide cushioning inside.

In addition, the operating lever shown in Figure 2 also has the same upper and lower 111[1M sections as the above-mentioned Pukuket excursion fork shaft, and also 111[1M sections] and 111 sections 0
(9m)-(9-)・(
9b) is for setting the mounting height for the fungal terminal @Ta1 and changing the mounting depth for the other.

In order to achieve the above, the present invention is applicable to the field that has been set to -. The i ground member (to) is attached to the desired color arrangement ground member (6) so that it can be raised and lowered freely, and it is mechanically compliant so that it can be raised and lowered integrally with the ground member (9b) and in mutually opposite directions. It is characterized by ◆, which is IIJ connected.

In other words, if the grounding member (9b) tries to rise, it will push the I auxiliary grounding member α- into the mud, so the resistance of the 11I auxiliary grounding member bending into the mud will cause the WI grounding member to rise. Ascending resistance is provided to the member (9b), and
Mud soil force/Hard soil The upward resistance given to the grounding member (9b) becomes large ◇Therefore, by setting the downward biasing force of the grounding member (9b) to a value suitable for soft muddy soil, muddy soil In the soft theory frVc, since the downward biasing force of the ν ground member (9b) is excessive, the ground member (9b)
) is prevented, and in places where the mud is hard, the ground contacting member (9b)'s ability to push down and sink against the mud and foreign objects is greater than that when the mud is soft. Automatic fishing is a big help in preventing the grounding member (9b) from rising unnecessarily due to lumps of mud or foreign matter, and causing leakage. In order to be able to keep the depth of the cage at a constant level, 1.
For that purpose, a special 11-hand opening sound function has been created, allowing the work to be carried out more efficiently.By the way, the biasing force is applied to the mud hardness detection mechanism based on the detection result. When using 11wt4 to force the grounding member to move downward with a spring that is linked in such a way as to be adjusted, the spring action
In order to have a smooth meeting, it is necessary to construct a cover 11B to prevent mud from adhering to it.
According to the above configuration, the ridge side pond member (9b) and shouting series WJI
III Taket Rod (2), Link (12si), (1
As shown in 2b), it can be constructed with a simple device that is less likely to malfunction due to adhering mud compared to a spring, and is also excellent in terms of economy and maintenance.
