Description

Rice transplantation {RICE TRANSPLATER}

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a rice milling machine for transmitting power to a food arm via a subunit mechanism.

In the conventional rice milling machine, if the trajectory of the feeding end is set to be almost vertical in the vicinity of the bottom dead center on the basis of the tightening (dense planting), in the sparse planting state, ), It is likely to cause a phenomenon in which the seedlings that have been fed are pushed forward. On the contrary, if the trajectory of the tip of the feeding aid is set so as to be almost vertical in the vicinity of the bottom dead center, on the basis of the news, in the state of wheat, the feeding aid moves backward while entering the rice field, and the seedling is disturbed, .

For this reason, in order to move the food tanks more quickly out of the field than on the basis of the tumbled state, a differentiating mechanism is provided to change the angular speed (rotational speed) during one rotation of the rotary food arm shaft supporting the food tumbler There is a way.

Japanese Unexamined Patent Application Publication No. 2003-102214 discloses a technique in which a semi-constant speed transmission mechanism is provided inside a mission case to change the angular speed during one rotation, thereby completing the following manner. That is, the distance of the seedlings through which the seedlings pass through the lower portion of the seedlings and the distance of the seedlings from the seedlings from the seedlings, and the descending distance And a slow section is provided at a rising distance from the surface to the seedling bearing end, thereby achieving a good seedling drawing operation and a food feeding operation.

Since the semi-constant speed transmission mechanism accelerates and decelerates the angular speed during one rotation of the rotary shaft, the torque fluctuation (load variation) applied to the rotary shaft becomes large. The rotation axis is twisted and the twist release is repeated to cause irregular rotation of the drive system due to a backlash of gears constituting the drive system or rattling caused by gaps between the components during manufacture of the drive system or twisting of the drive system, Resulting in poor food quality.

Therefore, the present invention provides a rice cooker for preventing the faulty food by optimizing the trajectory of the food coarse by improving the phase difference by leveling the torque fluctuation by imparting a torque for eliminating the torque fluctuation occurring on the food arm axis.

The rice planting machine of the present invention is a rice planting machine for transferring power to a vegetable arm axis for supporting a rotary case through a subordinate mechanism, wherein the vegetable arm shaft is driven through a chain in a case of a food part, The torque leveling mechanism is mounted on the sprocket of the chain drive.

The term " mounting the torque leveling mechanism to the sprocket of the chain drive " includes not only mounting the sprocket directly in the sprocket in the food chain case but also indirectly mounting it on a part of the chain drive constituted by the sprocket chain, It may be mounted on a chain or mounted on a shaft on which the sprocket is fixed. In other words, the present invention broadly includes an embodiment in which a leveling torque is imparted to a chain in a food chain case.

The torque leveling mechanism is provided on an optional drive shaft that is increased from the food arm axis and is transmitted.

The torque leveling mechanism is provided on a connecting plate provided between the rotor arm shafts supporting the food tanks.

The rice-growing machine 1 will be described with reference to the accompanying drawings.

The plowing machine 1 drives the front wheel 3 and the rear wheel 4 by the power of the engine 2 and travels while the plowing machine 5 performs a cooking operation. The power of the engine 2 is transmitted to the front wheel 3 and the rear wheel 4 via the transmission case 6 and is transmitted to the rear end portion 5 via the transmission case 6 and the span changing device 9, .

The food compartment 5 includes a food center case 10, a food chain case 11, a rotary case 12, a food arm 13, a seedling rack 14, and a plurality of floats 15.

Fig. 2 is a power system diagram of driving of the food part of the food part 5. Fig.

The power of the engine 2 is transmitted to the food center case 10 through the food transfer shaft 20 branched from the transmission case 6. Is transmitted to the transmission shaft (22) by a pair of bevel gears (21) in the food center case (10). A sprocket chain 24 is fixed to the gear 23 on the transmission shaft 22 and is transmitted to the food-transverse axis 40 in the case-case chain 11 through the sprocket chain 24.

The four take-out amount adjusting driven gears 27, which are relatively rotatably supported by the transmission shaft 26, are transmitted to the transmission shaft 26 fixed to the gear 25 engaged with the gear 23, One of which is rotated with the transmission shaft 26 by means of the slide key 28. Then, one take-out amount adjusting spur gear 29 corresponding to the take-out amount adjusting driven gear 27 rotates and is transmitted to the transverse feed shaft 30.

And is transferred to the vertical transfer shaft 32 through the sprocket chain 31 to transfer the seedling mat on the seedling rack 14 vertically downward.

To the unit clutch (41) in the case (11), which is a food portion, from the food-portion transverse axis (40).

Is transmitted to the sprocket (42) fixed to the unit clutch (41) when the unit clutch (41) is in the connected state due to intermittent interruption. The chain 45 is wound on the sprocket 42 provided on the sprocket 42 and the unit clutch 43 on the rotary case side. On the other hand, when the unit clutch 41 is disengaged, it is not transmitted to the sprocket 42. The unit clutch 41 is a safety clutch, and the connected state is normally maintained.

When the connection state is established by the intermittent operation of the unit clutch 43, the connection is transmitted to the food arm shaft 46 through the sprocket 44 and the chain 45. On the other hand, when the unit clutch 43 is disengaged, it is not transmitted to the food arm shaft 46.

The food arm shaft 46 extends into the rotary case 12 provided on the right and left sides of the case 11 as a food part and is fixed to the rotary case 12. [ The rotary case 12 is rotated and is transmitted from the sun gear 50 fixed to the case 11 as a food bowl to the planetary gear 52 through the intermediate gear 51. [ Then, the food arm 54 is transferred to the food arm 13 fixed to the planetary gear 52 via the rotor arm shaft 53, and the food container 54 is rotated together with the rotary case 12, Can be extracted and planted.

[Subsidiary Organization]

The power is transmitted from the mission case 6 to the food center case 10 through the period changer 9. A subunit rotation mechanism of the subunit mechanism provided in the subunit changing device 9 is transmitted to the subunit arm shaft 46 within the subunit changing device 9.

That is, when the food trough 54 takes out the seedlings from the seedling rack 14 and quickly pulls out the food trough 54 from the field after the seedling is taken out, and drops the seedlings remaining in the food trough 54 The rotation of the rotary case 12 is accelerated and the rotating speed of the rotary case 12 is slowed down before the seedling is fed into the field of rice and the seedling trough 54 is pushed into the seedling tray 14.

As described above, power is transmitted to the food arm shaft 46 through the subordinate speed mechanism and is rotationally driven with periodic acceleration / deceleration. As a result, a torque fluctuation caused by the parallax motion occurs in the food arm shaft 46. Specifically, since the seedling of each of the food tanks 54 is accelerated / decelerated on the basis of the take-off and the bushing, the torque fluctuation due to the sub-ordinate motion is detected It becomes a periodic fluctuation.

On the other hand, depending on the number of periods to be set by the period changing device 9, such as in the case of a continuous type, the power may be transmitted at a constant speed.

In addition, since the seedling copulation 54 needs to pull the seedlings out of the seedling rack 14 in an oblique posture as viewed from the side, and then the seedling should continue to descend toward the field of rice at a position close to the vertical, The sun gear 50, the intermediate gear 51 and the planetary gear 52 in the rotary case 12 are eccentrically non-circular. For the same reason as the food arm axis 46, the rotor arm shaft 53, which supports the food arm 13, is also rotated by the variable speed mechanism at a variable speed relative to the rotary case 12.

[Torque equalization mechanism]

As shown in Figs. 2 and 3, a torque leveling mechanism 60 is provided on the food arm shaft 46. Fig.

The torque leveling mechanism 60 includes a sprocket 61 fixed to the food arm shaft 46, a sprocket 63 fixed to the optional drive shaft 62 for driving options such as a herbicide sprayer and a box sprayer, A crankshaft 65 extending from the optional drive shaft 62 serving as the rotation center of the sprocket 63 to the outside of the case chain 11, And a coil spring (66) connected to the crankshaft (65). The number of teeth of the sprocket 61 is twice that of the sprocket 63 and the number of rotations of the optional drive shaft 62 is twice the number of rotations of the food arm shaft 46, do.

A boss 67a for fixing one end of the coil spring 66 to the crankshaft 65 is provided. One end of the coil spring 66 is fixed to a boss 67a provided on the crankshaft 65 and the other end is fixed to a boss 67b provided outside the case 11 as a food part. Further, the position of the boss 67b is determined so that a force acts on the coil spring 66 in the direction of always contracting.

In the torque leveling mechanism 60, the sprocket 61 rotates with the rotation of the food arm shaft 46, and the sprocket 63 rotates around the optional drive shaft 62 through the chain 64. The crankshaft 65 is rotated at a position eccentric from the center of rotation of the sprocket 63 with the rotation of the sprocket 63 and the length of the coil spring 66 is changed so that an elastic force is generated in the coil spring 66 . The elastic force generated in the coil spring (66) is transmitted to the sprocket (63) through the crankshaft (65). Then, it is transmitted to the sprocket 61 through the chain 64 and imparted to the food arm shaft 46 as torque.

The power transmission from the food arm shaft 46 to the crankshaft 65 is only required to be such that the rotational speed of the crankshaft 65 side is twice the rotational speed of the food arm shaft 46, May be used.

The mechanism that generates torque in conjunction with the rotation of the optional drive shaft 62 that rotates interlockingly with the food arm shaft 46 through the sprocket chain includes a crank shaft 65 and a coil spring 66, The present invention is not limited to the mechanism, and a cam-spring mechanism constituted by a cam that rotates together with the optional drive shaft 62 and a leaf spring that applies an elastic force to the cam may be employed.

The torque imparted by the torque leveling mechanism 60 will be described in detail with reference to Figs. 3 and 4. Fig.

On the other hand, in the figure, the food arm shaft 46 rotates counterclockwise. As a result, the sprocket 61 rotates counterclockwise, and the sprocket 63 also rotates counterclockwise.

4 (a), when the crankshaft 65 is located on the lower side, that is, on the side where the contracting force by the coil spring 66 is the same as the rotational direction of the sprocket 63, the coil spring 66 generates a torque in the same direction as the rotational direction of the sprocket 63. [ The torque generated in the sprocket 63 through the crankshaft 65 is transmitted to the food arm shaft 46 through the sprocket 61 as it is. At this time, the food arm shaft 46 is given a torque toward the acceleration side.

4 (b), when the crankshaft 65 is located on the upper side, that is, on the side where the shrinking force by the coil spring 66 is opposite to the rotating direction of the sprocket 63, the coil spring 66 generates a torque in a direction opposite to the rotational direction of the sprocket 63. [ The torque generated in the sprocket 63 through the crankshaft 65 is transmitted to the food arm shaft 46 through the sprocket 61 as it is. At this time, the food arm shaft 46 is given a torque toward the deceleration side.

The crankshaft 65 rotates about the sprocket 63 so that the elastic force generated on the crankshaft 65 due to the expansion and contraction of the coil spring 66 is transmitted to the crankshaft axis 46 as a periodic torque do. More specifically, the position and angle of the boss 67b, which is the fixed end of the coil spring 66, and the tip end of the crankshaft 65, that is, the position and angle of the crankshaft 65 with respect to the sprocket 63, A fluctuating torque is generated to draw a curve close to the curve.

As shown in Fig. 5, the period of the torque generated by the torque equalizing mechanism 60 is adjusted to the period of the torque fluctuation occurring on the food arm shaft 46 by the sub-constant velocity mechanism, and the torque fluctuation caused by the sub- (In the figure, to be opposite in phase).

At this time, since the sprocket 63 to which the crankshaft 65 is fixed rotates twice the number of revolutions of the food arm shaft 46, the torque equalizing mechanism 60 is provided with the two A periodic torque is generated. That is, the torque leveling mechanism 60 can eliminate the periodic torque fluctuation having two peaks that occur during one rotation of the rotary case 12 via the semi-constant velocity mechanism, and can generate a leveled torque.

Thus, by adjusting the period of the torque leveling mechanism 60 to the period of the torque fluctuation by the subordinate speed mechanism, the torque is combined to suppress the torque fluctuation caused by the subordinate speed mechanism.

On the other hand, in the present embodiment, the counter-phase equalization torque is given to the torque variation caused by the sub-variable mechanism, but it may not be the complete anti-phase equalization torque as long as the torque variation is effectively suppressed. For example, it is also possible to eliminate the torque fluctuation by giving a leveling torque appropriately set to 30 deg. Or 45 deg. To the torque fluctuation. In this case, it can be appropriately set by changing the timing of the torque generating mechanism (the crankshaft 65 and the coil spring 66 in the present embodiment).

As described above, the torque leveling mechanism 60 applies a smooth torque having a period equal to the period of the torque fluctuation caused by the subordinate velocity mechanism (two cycles per rotation of the rotary case 12), thereby leveling the torque fluctuation, The phase difference of the arm shaft 46 can be improved. As a result, the food arm shaft 46 can be smoothly rotated at a uniform speed without twisting or rattling, thereby making it possible to stabilize the trajectory of the food tanks 54 during high-speed rotation, thereby preventing defective food.

Since the torque leveling mechanism 60 is directly mounted on the food arm shaft 46 through the structure of the chain or the gear, the torque leveling mechanism 60 can be positioned close to the rotary case 12 which causes the torque fluctuation. Therefore, it is possible to effectively impart the torque fluctuation in the reverse phase, thereby increasing the effect of leveling the torque fluctuation.

Although the torque leveling mechanism 60 is disposed at a position away from the one shaft (the optional drive shaft 62) in the food arm shaft 46, the shaft to which the torque is applied is an optional drive shaft such as a herbicide spreader or a box- It is possible to easily secure the space in the case 11, which is a food chain, and to mount it without difficulty.

The torque leveling mechanism 60 is provided for each of the food units in which the food arm shaft 46 is provided. In other words, by eliminating the torque fluctuation caused by the acceleration / deceleration of the rotary case 12 in the unit because the leveling torque does not rise up to the upstream of the electric motor system, the fluctuation of the diaphragm 54 can be suppressed have.

[Other Embodiments]

Figs. 6 to 11 show another embodiment of the torque leveling mechanism 60. Fig.

In the embodiment shown in Fig. 6, a torque equalizing mechanism 60 is provided on the eating-part transverse axis 40. Fig.

The torque leveling mechanism 60 has a crankshaft 65 provided on the horizontal axis 40 which is the rotational center of the sprocket 42 on the upstream side and a coil spring 66 connected to the crankshaft 65.

Here, similarly to the above, the sprocket 42 rotates with the rotation of the food transverse axis 40, and the sprocket 44 rotates around the food arm axis 46 through the chain 45. The crankshaft 65 is rotated at a position eccentric from the center of rotation of the sprocket 42 with the rotation of the sprocket 42 and the length of the coil spring 66 is changed to generate an elastic force in the coil spring 66 . The elastic force generated in the coil spring 66 is transmitted through the chain 45 from the sprocket 42 to the sprocket 44 through the crankshaft 65 and is imparted to the food arm shaft 46 as a leveling torque.

Since the sprocket 42 to which the crankshaft 65 is fixed likewise rotates twice the rotational speed of the food arm shaft 46, the torque equalizing mechanism 60 is provided with the sprocket 42, Two cycles of torque are generated. In other words, the torque leveling mechanism 60 can eliminate the periodic torque fluctuation having two peaks that occur during one rotation of the rotary case 12 via the sub-speed mechanism to generate a leveled torque.

Thus, by adjusting the period of the torque leveling mechanism 60 to the period of the torque fluctuation by the subordinate speed mechanism, the torque is combined to suppress the torque fluctuation caused by the subordinate speed mechanism.

The elasticity of the coil spring 66 serving as an elastic body is used to suppress the occurrence of nonuniformity in the rotation of the drive system caused by the backlash of the gears constituting the drive system or the rebound caused by the clearance formed between the parts in manufacturing the drive system. As a result, the food arm shaft 46 can be smoothly rotated at a uniform speed without twisting or rattling, thereby stabilizing the trajectory of the food trough 54 at high speed, thereby preventing defective food. In this way, the same effect as that of the above-described torque equalizing mechanism 60 is obtained.

Further, by providing the torque leveling mechanism 60 in the horizontal axis 40 of the food part in the case 11, the whole length can be made compact without being elongated, and the additional parts are only crank- Is also advantageous in terms of cost.

In the embodiment shown in Fig. 7, the torque leveling mechanism 60 is provided on the connecting plate 70 fixed between the rotor arm shafts 53 that support the pair of food arms 13. Fig. The torque leveling mechanism 60 is provided at the center of rotation of the connecting plate 70 and is in contact with the cam 67 and the cam 67 rotating together with the connecting plate 70, A pair of leaf springs 68 are provided. The cam 67 is formed with a cam surface having two diametric changes in one cycle.

As the connecting plate 70 rotates together with the food arm 13, the cam 67 rotates together with the connecting plate 70 to expand and contract the leaf spring 68, so that the leaf spring 68 generates elastic force. The elastic force is transmitted to the rotor arm shaft 53 through the connecting plate 70. And is imparted as torque to the food arm shaft 46 through the sun gear 50, the intermediate gear 51, and the planetary gear 52. [

In the embodiment shown in Fig. 8, the torque leveling mechanism 60 is provided on the downstream side sprocket 44 which is fixed to the food arm shaft 46. Fig.

The torque leveling mechanism 60 includes a sprocket 42 fixed to the food transverse axis 40, a sprocket 44 fixed to the food arm axis 46, a chain 45 interlocking the sprockets 42 and 37, And two leaf springs 81 fixed to the sprocket 44 and capable of contacting the cam 80 and cam 80 having two periods of cam surfaces and extending and retracted by the rotation. In this case, the number of teeth of the sprocket 42 is equal to the number of teeth of the sprocket 44.

The camshaft 80 is rotated in the direction in which the leaf spring 81 is extended so that the urging force of the leaf spring 81 to return to its original position is transmitted to the nut member 46 on the decelerating side As shown in Fig. As the cam 80 rotates in the direction in which the leaf spring 81 is returned to the original position, a force in the same direction as the rotational direction of the plate spring 81 is transmitted to the plate arm shaft 46 And is imparted as a torque to the acceleration side.

That is, the leveling torque imparted by the torque leveling mechanism 60 becomes a periodic variation with two peaks during one revolution of the food arm shaft 46. [

At this time, since the sprocket 44 to which the cam 80 is fixed rotates at the same rotational speed as the food arm axis 46, the torque leveling mechanism 60 is generated during one rotation of the rotary case 12 by the sub- The torque can be generated by eliminating periodic torque fluctuations having two peaks.

In the embodiment shown in Fig. 9, the torque leveling mechanism 60 is provided in the chain 45 for interlocking the food-transverse axis 40 and the food-arm axis 46 together.

The torque leveling mechanism 60 includes a sprocket 42 fixed to the food transverse axis 40, a sprocket 44 fixed to the food arm axis 46, a chain 45 interlocking the sprockets, a chain 45, A leaf spring 90 for adjusting the tension by varying the length of the cam 90, and a cam 91 having two periods of cam surfaces. The cam 91 is rotationally driven by the electric motor or the like in accordance with the rotation of the sprocket / chain mechanism.

As the cam 91 is rotated and pressed in the direction in which the leaf spring 90 is extended, the tension of the chain 45 is increased and given to the sprocket chain as a torque to the deceleration side. The rotation of the cam 91 in the direction of returning the leaf spring 90 to its original position reduces the tension of the chain 45 and is applied to the sprocket chain as a torque toward the acceleration side.

By adjusting the rotation speed of the cam 91, the leveling torque imparted by the torque leveling mechanism 60 can be a periodic variation with two peaks during one rotation of the food arm shaft 46. [ Therefore, periodic torque fluctuations having two peaks occurring during one rotation of the rotary case 12 by the subordinate speed mechanism can be eliminated and a normalized torque can be generated.

In the embodiment shown in Fig. 10, the torque leveling mechanism 40 is provided on the connecting plate 70 which connects the two rotor arm shafts 33 provided in the rotary case 12.

10A, the two fins 71 protruding from the connection plate 70 toward the outer side are disposed between the food arm shaft 46 serving as the rotation center of the rotary case 12 And is provided at a symmetrical position. The ring 72 covering the two fins 71 from the outer circumferential side is formed into a square shape having a length between the fins 71 as an inner circumferential side. A coil spring 73 is fixed to the center of the side of the ring 72 opposite to the side contacting the pin 71.

The pin 71 rotates around the food arm shaft 46 and pushes down the inner circumference of the ring 72 as the rotary case 12 rotates, as shown in Fig. 10 (b). As a result, the coil spring 73 is stretched to generate an elastic force. The elastic force of the coil spring 73 thus generated is transmitted to the food arm shaft 46 through the connecting plate 70 and the rotary case 12 as torque. When the rotary case 12 rotates once, the positional relationship between the pin 71 and the ring 72 changes in two cycles in which the coil spring 73 is stretched-shrink-stretch-contract. That is, it is possible to impart the torque fluctuation occurring in the food arm axis 46 and the equalizing torque in the same period.

As a more preferable embodiment, the flange shape of the pin 71 may increase the contact area with the ring 72 or reduce the resistance between the pin 71 and the inner peripheral surface of the ring 72 by attaching a roller .

Alternatively, the ring 72 may be formed in a triangular shape. The coil spring 73 can be stably fixed.

In the embodiment shown in Fig. 11, the torque leveling mechanism 40 includes a timing cam 100 fixed to the horizontal axis 40, a solenoid 101 operated at a timing set by the timing cam 100, and a solenoid 101 And a micro switch 82 connected to the solenoid 81 and operating the solenoid 81 by flowing a working current.

11 (a), the timing cam 100 has a stepped surface 100a extending in the radial direction, and the large-diameter portion and the small-diameter portion are formed adjacent to each other in the circumferential direction with the stepped surface 100a interposed therebetween do. The solenoid 101 is disposed above the micro switch 102, and its proximal end portion is rotatably supported. The switch portion of the microswitch 102 is disposed at the upper portion, that is, below the solenoid 101. The plunger 101a of the solenoid 101 is disposed along the cam surface of the timing cam 100. [

11 (b), when the plunger 101a of the solenoid 101 passes the stepped surface 100a, it falls from the large-diameter portion to the small-diameter portion. Thus, the solenoid 101 rotates and comes into contact with the switch portion of the micro switch 102, so that a working current flows from the micro switch 102 to the solenoid 101. Then, the plunger 101a of the solenoid 101 presses the step surface 100a. In this way, the impulse torque is imparted to the eating-part transverse axis 40 through the timing cam 100. [

The timing by the timing cam 100 is set at a timing at which the maximum torque is generated in the torque fluctuation caused by the subordinate velocity mechanism. As a result, the impulse torque is generated so as to eliminate the maximum torque.

As described above, since the operation time is shortened by giving the leveling torque as the impulse torque, the timing difference is hard to occur. Furthermore, since the rotation is assisted by the impulse torque, it is not braked by the rotational load. Further, since the driving force applied to the torque application is independent of the rotational driving force of the rotary case 12, it is not affected.

On the other hand, in the case of being provided on the food arm shaft 46 instead of the food horizontal shaft 40, the step cam 100 is provided on the food arm shaft 46 by providing the step cam 100a having a phase difference of 180 degrees on the timing cam 1080 A leveling torque corresponding to the period of the generated torque fluctuation can be given.
