That is, it is mounted on the rear of the tractor, excavates with a claw member fixed to the rotating rotor shaft on the ridge of the field and the surface of the old ridge, lifts the soil on the ridge, and uses the ridge shaping member with vibrator A ridge coater that has a drive mechanism that transmits between an input shaft, a drive shaft for a vibrator, a rotor shaft, and a counter shaft that rotates in the opposite direction to the input shaft. Installed on both sides, input the tractor-side power to the tractor from the input shaft when installing the front part of the ridge coater, and input the tractor-side power from the counter shaft when installing the rear part. It was configured as follows. [0005] By attaching the rear side of the ridge coater to the rear of the tractor and transmitting power from the PTO shaft on the tractor side to the counter shaft, the drive direction of the drive mechanism of the ridge coater does not change, and The work can be done by pushing the ridge coater from behind. The problems and constitutions to be solved by the present invention are as described above. Next, embodiments of the present invention shown in the attached drawings will be described. 1 is a side view showing a mounting structure of the ridge coater A to the tractor TR, FIG. 2 is a plan view of the ridge coater A, FIG. 3 is a rear view thereof, and FIG. 4 shows a belt transmission mechanism in the power transmission box 9. FIG. 5 is an overall view of the vibrating part drive mechanism, and FIG. 6 is a schematic plan view of the entire field showing an unlined portion when the tractor TR is mounted from behind the liner A. [0007] In the configuration of the ridge coater A, first, the method of mounting to the tractor TR and the power transmission method are shown in Figs.
A more detailed description will be given. At the rear of the tractor TR, a quick hitch type work implement mounting device including three links of a top link 29 and left and right lower links 30L and 30R protrudes. On the other hand, in the ridge coater A, the upper support bar 1 and the left support plate 2 are extended before and after the power transmission box 9, and
A front right support plate 3F extends forward and a rear right support plate 3R extends rearward. Top link pivot pins 1a and 1b and lower link pivot pins 2a and 2b project from the front end and the rear end of the upper support rod 1 and the left support plate 2, respectively. At the front end of the lower link pivot pin 3a,
A lower link pivot pin 3b is protruded from the rear right support plate 3R. In this way, when the tractor TR is towed by the forward drive, each pivot pin 1a
When the rear ends of the top link 29, the left lower link 30L, and the right lower link 30R are connected to the 2a and 3a, respectively, and the tractor TR is driven backward by pushing the ridge coater, the rear of the ridge coater is used. , The rear ends of the top link 29, the right lower link 30R, and the left lower link 30L are pivotally connected to the respective pivot pins 1b, 2b, 3b. In the power transmission box 9 of the ridge coater A, an input shaft 4, a counter shaft 5, a hydraulic pump shaft 6, and a rotor shaft 7 are supported by bearings in parallel.
A power transmission chain 8 is wound between the shafts. The counter shaft 5 is a shaft that supports a tension sprocket for tensioning the chain 8, and the input shaft 4
And rotate in the opposite direction. The input shaft 4 protrudes forward from the power transmission box 9, and when pulling the ridge coater by the forward drive of the tractor, the input shaft 4 is input from the PTO shaft of the tractor via the joint shaft 31 from the front. To 4 On the other hand, as shown in FIG. 1 or FIG. 5, the counter shaft 5 projects rearward from the power transmission box 9 and, via the joint shaft 32, the left support plate 2 and the rear right support plate 3
R is connected to a coupling shaft 33 supported between the respective rear ends, and the PTO shaft of the tractor TR can be connected to the coupling shaft 33 via the joint shaft 31. The ridge coater can be driven by inputting power on the tractor TR side from the rear end of the counter shaft 5, and the ridge coater can be pushed from behind by the reverse drive of the tractor TR. As described above, since the rotation direction of the counter shaft 5 is opposite to that of the input shaft 4, when the power is transmitted from the PTO shaft to the counter shaft 5 from behind, the driving direction of the chain 8 is the same. With the above-described structure, the tractor TR is mounted from behind the ridge coating machine A in the unlined portion which has been generated when the tractor TR is driven by the forward drive of the tractor TR. Is applied by pressing the tractor TR with the tractor TR.
The length of the ridge can be applied to the ridges.
As described above, only the front and rear length L of the ridge coater A is left.
In other words, the number of unlined portions is extremely small, and even if lining is manually performed later, the work range becomes very small, and the work efficiency is greatly increased. Next, an explanation will be given of a mulching rotor 7a, which is a claw member for excavating and burying the soil at the ridge portion of the field. A rotor shaft 7 protrudes rearward from the power transmission box 9, and a mulling rotor 7 a is fixed to a rear protruding portion of the rotor shaft 7, and a guide box 10 covers the periphery thereof. The mulching rotor 7a is a claw-shaped claw member having a curved shape as shown in FIG. 3 when viewed from the front. The mud for new ridges is placed on the surface of the ridges cut by the provided surface cutting plows 11, and as shown in FIG. It is made up of a projecting rearward slope to move the soil backward. The mud repelled by the mulch rotor 7a is guided on the ridge by the inner surface of the mud guide cover 12 arranged on the right side of the guide box 10. The mud guide cover 12 is supported by a guide cover support rod 14 from the side of the vibrating section support mechanism.
When the vibrating part is moved up and down by the operation of 7, it moves up and down together with the ridge shaping plate 13. Next, a description will be given of a vibrating portion driving mechanism and a supporting mechanism of the ridge shaping plate 13. FIG. As shown in FIG. 3, the vibrating section drive mechanism is supported by a parallel link support rod 18 protruding from the power transmission box 9 and a vibrating section adjusting mechanism 17. The vibrating part adjusting mechanism 17 rotates an internal screw rod by a driving motor provided at an upper part thereof, so that the parallel link 20.

The floating link 19 and the parallel link 21 are pivotally connected by a pivot 24. When the pivot 24 is freely bendable, the height thereof is adjusted by the vibrating section adjusting mechanism 17. The ridge shaping plate 13 is in a floating state in which it can freely move up and down. It is the floating lock arm 25 that restricts the floating state and regulates the floating state at the position adjusted by the vibrating section adjusting mechanism 17. The floating lock arm 25 rotates to lock the floating pin with the lock pin 21 a protruding from the parallel link 21. The free floating is regulated by engaging the lock arm 25 and locking it in a long hole formed in the arm cover 25a behind the floating lock arm 25. The mechanism for driving the vibrating section of the ridge shaping plate 13 will be described. As shown in FIG. 5, the hydraulic oil from the hydraulic pump P driven by the hydraulic pump shaft 6 is transmitted to the hydraulic motor M by piping, and the hydraulic motor M is rotated. The two sets of eccentric weights 16 and 16 provided inside the vibration mechanism B which is suspended from the illustrated spring suspension body 15 via the springs 15a and 15a. Is given. FIG.
In place of the hydraulic oil from the hydraulic pump P, the hydraulic motor M can be driven by hydraulic oil from the hydraulic pump H for lifting and lowering the work implement on the tractor side. In addition, a flow control valve V is provided between the hydraulic pump P or the hydraulic pump H and the hydraulic motor M, and the frequency and amplitude can be changed by adjusting the flow control valve V. Also, a hydraulic oil tank T for the hydraulic pump P and the hydraulic motor M
However, as shown in FIGS. 2 to 4, the power transmission box 9 is attached to the rear surface of the power transmission box 9 together with the hydraulic pump P. As another member, as shown in FIGS. 2 and 3, a sled body height adjusting handle 26 is provided to adjust the ground contact height of the sled body supporting the ridge coater from below. At the rear, a backfill plow 27 for backfilling the soil at the levee excavated by the burrow rotor 7a is provided,
A moving wheel 28 is provided on the front and rear so that the ridge coater detached from the tractor can be moved. The moving wheel 28
Is configured to be freely protruded and stored. The present invention is configured as described above, and has the following effects. That is, conventionally, the ridge coater cannot be pulled by the forward drive of the tractor, and at the end of the ridge, the front and rear lengths of the tractor and the ridge coater are left in a state where the ridge coating cannot be performed, and manual work is performed later. Although it was necessary, with the configuration of the mounting mechanism of the present invention, the tractor was mounted from the rear side of the ridge coating machine, and the tractor was able to work by pushing the ridge coating machine with the reverse drive, so that it was conventionally left. In the previously unlined part, the length of the tractor can be applied to the front and back of the tractor, and the unlined part is only the front and rear length of the ridge coating machine. Work efficiency is greatly improved.
