Abstract

(57) [Summary] [Purpose] The vibrator that vibrates the shore-lined orthopedic plate can be adjusted according to the soil conditions so that the vibration direction can be adjusted. [Structure] A timing belt 5 is mounted on both toothed wheels 4a, 4b coaxially mounted on both eccentric weights 1a, 1b, and the upper and lower portions of the timing belt 5 are placed between the toothed wheels 4a, 4b. An upper wheel 6a and a lower wheel 6b, which sandwich the upper and lower surfaces thereof and are pressed against the upper and lower surfaces thereof, can be simultaneously adjusted vertically with a predetermined interval.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vibrating direction adjusting device for a vibrator for a shore coater, which can shore the paddy field by vibrating the shore coat shaping plate by a vibrator.

[0002]

[Prior Art]

 Conventionally, in a side coater that can perform side coating while vibrating the side coating shaping plate by a vibrator that is oscillated by two rotatable eccentric weights mounted in parallel, a drive belt is provided on each axis of both eccentric weights. The eccentric weights were simultaneously driven to rotate by transmitting from one shaft.

[0003]

[Problems to be solved by the device]

 However, since the phase of both eccentric weights is fixed, the trajectory of the vector of the excitation force due to both eccentric weights remains constant regardless of the soil conditions on the shore, and therefore the finish result of the shoreline shaping is soil. The problem was that it was affected by the conditions.

[0004]

[Means for Solving the Problems]

 The present invention has been devised to solve such a problem and to adjust so that the optimum vector locus of the exciting force can be obtained according to the soil condition of the shore, and therefore, the two eccentric weights are coaxially attached to each other. A timing belt is mounted on both toothed wheels, and an upper wheel and a lower wheel, which are pressed against the upper and lower surfaces of the timing belt so as to sandwich the timing belt between the toothed wheels, move up and down simultaneously with a predetermined interval. It is configured to be adjustable.

[0005]

[Action]

 Therefore, if the upper wheel and the lower wheel are adjusted up and down at the same time, the up and down movement can simultaneously rotate both teeth via the timing belt in opposite directions. Since the phase of the weight is adjusted, it can be adjusted to obtain the optimum vector locus of the exciting force depending on the soil condition of the shore, and the shore-painting with a good finish can be performed.

【Example】

 FIG. 6 shows the main part of the levee coater, which is constructed so that the vibrator 2 mounted on the upper part of the levee coat shaping plate 3 that can be used for levee coats in the paddy field can be supported from the support frame 7 via each ammunition 8. In the case 2a of the vibrator 2, parallel eccentric weights 1a and 1b are mounted on parallel rotary shafts 9a and 9b, respectively, and have the same diameter on both rotary shafts 9a and 9b. A timing belt 5 is hung on both toothed wheels 4a and 4b, and an upper wheel 6a and a lower wheel 6b are vertically set on a bracket 11 which can be moved up and down by rotating an upper adjusting screw 10. As shown in FIG. 1, the upper and lower wheels 6a and 6b are attached to the upper and lower surfaces of the timing belt 5 so that the timing belt 5 is tensioned between the toothed wheels 4a and 4b. Each Is contact, the the rotary shaft 9a constitutes a flexible transmission shaft 12 extending from the machine side and transmission-coupled.

Therefore, when both the eccentric weights 1a and 1b are rotated in the arrow A direction as shown in FIG. 1 by being transmitted to the vibrator 2, the vibrator 2 vibrates to vibrate the embankment shaping plate 3. When the adjustment screw 10 is operated and the upper wheel 6a and the lower wheel 6b are simultaneously moved upward in the arrow B direction as shown in FIG. 5, the lower wheel 6b is moved to the middle portion of the timing belt 5. Both eccentric weights 1a and 1b rotate in the directions indicated by arrows c and d, respectively, because both tooth wheels 4a and 4b can be rotated in the opposite directions while lifting up the eccentric weights 1a and 1b. Therefore, the phase can be adjusted, and therefore, it can be adjusted to obtain the optimum vector trajectory of the exciting force depending on the soil condition of the shore, and the shore painting can be finished with good finish.

FIG. 7 shows a case where a shore coater is attached to the agricultural tractor A. A hydraulic motor 13 is attached to a side portion of the vibrator 2 and a rear PTO shaft 17 drives the rear portion of the agricultural tractor A. A hydraulic pump 14 capable of being mounted is installed, and the hydraulic pump 14 and the hydraulic motor 13 are connected in communication with each other via a pressure-feeding hose 15 and a return hose 16, so that the agricultural tractor A can be favorably transmitted to the vibrator 2. It is configured as follows.

8 to 11 show another example of the vibrator 2, in which both eccentric weights 1a and 1b are engaged with each other by engaging both gears 18 and 19 mounted on the shafts of both eccentric weights 1a and 1b, respectively. It is configured so as to rotate and oscillate in the opposite arrow E and F directions. As shown by the arrows in each figure, the vector of the centrifugal force of both eccentric weights 1a and 1b is shown in FIG. In the state shown in FIG. 11 and in the state shown in FIGS. 8 and 10, the phase is canceled in the left-right direction, and in the state shown in FIGS. 8 and 10, the force component remains only in the downward and upward vertical directions. While oscillating on the ground, it is possible to make the embankment-shaped plate act vertically on the soil surface.

[0010]

[Effect of the device]

 As described above, according to the present invention, when the upper wheel 6a and the lower wheel 6b are simultaneously adjusted in the vertical direction, the vertical movement of the upper wheel 6a and the lower wheel 6b simultaneously causes both the toothed wheels 4a and 4b to rotate in opposite directions at the same time. By adjusting the phases of the weights 1a and 1b, it is possible to adjust the vector locus of the optimum exciting force according to the soil condition of the shore, and to give the shore-coated orthopedic plate 3 optimum vibration. It has the advantage that it can be shaped with a good finish and can be suitably implemented with a simple structure.
