Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is designed to move a U-Tari tilling device connected to the rear VC of a tractor by a single ν1 type hydraulic ring or to raise it by lifting it by a foot arm. This article relates to a riding tiller from an oval perspective.

There are two methods for adjusting the plowing depth ηt'i in the tiller: (Inowheel gauge method) and (B) Bojinyon control method.

The wheel gauge method is the most common method that has been widely used for a long time, and it is the third most common method that has been used frequently for a long time.
Change the man to ilt (rising, neutral, falling) IJl' rf

- A mechanical type in which the operator manually rotates a screw handle for downward adjustment, and a hydraulic type in which a tilting w1 type hydraulic nolinder is created by operating a hand lever separately installed on the control section. There's crab.

In addition, the plowing depth adjustment means of the Boji Soyon JlIIJ m method,
The lift arm is moved up and down at a preset distance of 1/c1 according to the operating position of the manual lever (position setting lever) provided on the control l51 (1/c1), and is automatically stopped and held. Features that make the adjustment operation extremely easy
The plowing depth is determined by the undulation of the field, but the following problems arise: Paddy paddy 4m, etc.) m stock fi 14 sections and 1ζ square gage method e:i shown in Figure 8 J:su[1-roughy +II

) and the surface layer f! It may be necessary to carry out plowing and crushing, but it is not necessary to use a tiller (Gl is not necessarily hard and 1-), and there are also unevenness, so the aircraft is lowered. If the aircraft sinks significantly like this and sinks into the mud so deep that the entire tillage device (31) is almost completely submerged, the rotation of the tillage device (3) The component force in the aircraft rjtr forward direction of the interest payment reaction force due to undercut (Ik) decreases, and
dllll resistance resistance A due to adult subsidence: l-,, wheel slip occurred L'7 machine's l1IJ advance was 1 (1↓ sweet), so the wheels scratched the plowing plate, promoting r- and layered F. This could cause the engine to stop due to overload.

In this case, turn the screw handle 1) and use u+ 1- to forcefully lower the tail wheel attachment 71/-m (6) and use the tilling device as the fourth target! If /I3+ is increased, the rtiJ forward direction component of the tilling reaction force can be obtained, and the tilling device ζ7 (3) sinks, so the IJ forward resistance is small and the enemy can continue traveling in the nII forward direction, but at the working level O. Lowered tillage device 1a (3)
If the cow cannot reach the screw handle resting l) that was attached to the device 1tii, either stop the adult, get off and operate it, or remove the handle 1).
It was necessary to hold the entire cultivating device (3) with the lift arm (5) with two hands within reach. Power given.

The buoyant force that had been attached to it is gone, and it becomes easier to sink.
El and the lifting reaction force act on the rear end of the tractor il+, increasing the rear wheel load and promoting the tendency of the aircraft to float around the rear wheel axis, and the -J-rear wheel-'
It was to invite KJr. Especially in water 1'lJ, at least y! to increase thrust! Iar rear wheel gel Vc
Since a JIX single wheel is often installed on the rear wheel (20), the reaction force caused by the large body of the rear wheel (20) will encourage the front of the aircraft to roll forward and have a negative impact. is.

Therefore, +ke 1 of the 11 foot arm (6) is used to confirm the tendency of the adult to sink and move forward (- while operating the lever (to) quickly on and off, so-called inching operation to slightly turn on and off the tilling device (3). ). It is difficult to raise the tiller (3) by a small amount by inching the lever (C) while the tiller is in the L or L position, and requires a high degree of skill. was eight years old.

(tH)...Example of ridge tillage work When carrying out ridge tillage using the machine 1, section II wheel gauge method, as shown in Figure 5, move the VC1 tail wheel (7) to the edge of the ridge. Place the tiller on the tiller (&13+ to the desired tilling depth 7
It starts to advance, but as soon as the tail wheel (7) goes outside the ridge, the VC tilling device (31a) lowers under its own weight and the tilling depth becomes deeper. Either the operator can lift the tiller (3) with the II rough tome (5) and adjust the tail wheel from the observation position, or the operator can get off the tractor (1) and operate the screw handle (1) to adjust the tiller as desired. It is extremely troublesome to have to set the plowing depth. In addition, the plowing scars were deeper near the edge of the ridge and L-f. In addition, in order to avoid the trouble of such a tail wheel R1, "4 &ri, if you set the tail wheel set in advance and perform furrow tillage to reach the desired plowing depth, the tail wheel (7) The tillage device i+31 is lifted by the handle and the amount of t1 on the ridge is 45. ri) You won't be able to do it.

/, The land is leveled by plowing, and the plowing traces and VC tail wheel traces remain as groove-like VC, and the finish is reminiscent of this.Although it is also done to set up this plate/phantom. In this case, use the leveling plate (2).
There was a problem in that the ground pressure of the ground leveling plate ρ was high, and grounding 1 and E were performed more strongly than necessary. Also, in Figure 7, 1
There is also a method that does not set the plowing depth using the ground leveling plate (Incorporated) by hydraulically locking the 1 foot arm (6) or suspending the tilling device 11r13+ with a chain (to). In order to perform the leveling pressure using the screw handle e, it is necessary to set the RI7J section of the leveling pressure to 1 during the work.
If this happens, stop the aircraft and move your hand from the cockpit to the handlebar (1) until M'+ <.
Either the operator must lift the machine at 51 or get off and operate the handle, which is inefficient since the machine must be stopped at 51 and the leveled surface may be uneven. Met.

However, with this method, you can use the UJ lever (23) in one hand to adjust the plowing depth according to the conditions of the 11B1 field.
In order to avoid tc &t sagging, skilled techniques are required. Is the furrowing device 4 equipped with jIX? jta frame (6)
Adjust the sieve to approximately the same level and till the soil a little, then stop the bar, adjust the quality of the ridge, adjust the ridge surface using the IJk shape (+7't♂4, screw handle number 1), and use the ridge stand device (c). After adjusting the molding plate and the plow angle, plow again a little.

After repeating this operation, Y? However, this adjustment was extremely troublesome and inefficient. In addition, with this method, the plowing depth was set using the height of the ridge stand itself. Therefore, when the plowing depth is changed!Ii#l-, there is a tendency for unevenness of the ridges and the forming condition to be easily improved.

In addition, as shown in Figure 10, the tail wheel mounting frame (on) can be adjusted up and down with the oil f-E ring (8), and the furrow device 4 can be adjusted freely with the hand lever (3) even during operation. ni on 'F! 19+, which makes it easy to adjust the texture of the ridges, but the delicate slant angle adjustment of the ridge tool (c) itself was difficult.

By appropriately operating iJl (!0), you can adjust the height of the tiller (3) and tail wheel (7) without stopping the vehicle.In particular, the tiller (f&I31) can be adjusted slightly by a small amount. The operation to raise the position 2 times can be performed by using the two-way control lever (9).

tB)......Round tillage work During the furrow tillage work as shown in Figure 6, the tillage device (
By setting 3) to an appropriate position in advance from l/bar to 19) (corresponding to the lever in the figure), the plowing depth will not change even when moving away from the ridge. By the way, it seems that the tail wheel (7) is indispensable for VC during such tillage work, but in fields where there are localized hard and soft parts or undulations that cause the attitude of the machine to change significantly, it is necessary to use tillage with a fixed position setting. Since the plowing depth of the device F4 +31 varies greatly,
By using it in combination with the tail wheel (7), extreme fluctuations in plowing depth can be prevented. In other words, by setting the plowing depth according to the position setting to be a little deeper than the plowing depth set by the tail wheel (17), the plowing depth is normally maintained by making full use of the tail wheel (7), and the tail wheel ( Even when 7) is not effective, the depth of plowing can be ensured through the use of both the legs and the legs.

Then, the plowing depth adjustment by this position control and the tail wheel t7
