The present invention relates to a rice transplanter in which the hoisting operation is freely attached to the vehicle body freely by the drive device by the driving device.

In the rice transplanter, even if the body is slightly rolled to the left or right according to the unevenness of the arable land, the modeling device is held in parallel with the tilled ground by the relatively lowering of the modeling device on the cultivated ground relative to the body. Depth of planting on the left and right sides of the seedling device is constantly maintained, which causes inconvenience in that the seedling device rolls against the vehicle body.

That is, the above-described modeling device is capable of descending to an extremely low position with respect to the vehicle body so that a sufficient planting depth can be obtained even in a shallow arable land.

For this reason, even when the base material device is lowered and stored on a hard and flat ground or road surface other than arable land, or when the base material device is lowered to the lowest position when performing maintenance or cleaning, the free state material device is in contact with the ground. The lower limit is set so as not to be done, but when the external force is inadvertently applied, the seedling device is rolled, and the left and right ends of the modeling device are too close to the ground, so The member equipped in the lower part may deform | transform or damage.

In addition, since the modeling device is lowered even when the vehicle is mounted on a transport vehicle, the modeling device may roll and cause the same trouble as the shaking of the vehicle while driving.

A first object of the present invention is to prevent the occurrence of the above-mentioned obstacles due to unpredictable rolling in the descending mountain while setting the lowest position of the seedling device low.

In general, in this type of rice transplanter, the driving device and the modeling device between the elevating device and the modeling device are always in contact with the tilled ground even for some vertical movement or pitting of the vehicle body due to unevenness of the arable land. It is interposed with an elastic suspension mechanism that allows the relative lowering of the base material device relative to the drive device. The base material device is lowered to the lowest position, and external force is applied unexpectedly downward from the base material device. Since the suspension mechanism is elastically changed to the ground, the modeling material is lowered, and in this case, there is a risk that the lower member is changed or damaged.

Another object of the present invention is to prevent the obstacle caused by damage as the cause of the unexpected lowering of the base material device through the elastic suspension mechanism during the lowering.

The feature of the rice transplanter according to the present invention is that the above-described modeling device is provided with a fixing mechanism which automatically disables the above-described modeling device in the lowest position in which it floats on the ground according to the operation for lowering the vehicle body. Is as follows.

In other words, by setting the lowest position of the seedling device in the same way as the conventional one by the action of the fixing mechanism that makes the seedling device impossible to roll, the seedling device falls even if it is possible to measure the depth of planting even in shallow farmland. Since the rolling is fixed at the position, it can roll unexpectedly to contact the ground to prevent deformation or breakage of the float modeling tank, and also to the ground of the modeling device which may be in contact with the ground. Since the rolling is automatically fixed at the lowest and most injured position, damage to the rolling, etc., during planting caused by the forgetting of the fixing operation or the release operation when the fixing mechanism is simply installed and operated artificially. It can be surely prevented.

In addition, another feature of the present invention is to provide a drive device with an elastic suspension mechanism interposed between the drive device and the drive material device when the base material device is lowered to the lowest position in which it floats against the ground. The above-described fixing mechanism is configured to automatically suppress the relative drop of the representative material device.

According to this, deformation and damage of the lower member of the lowering material device by the lowering can be prevented through the elastic suspension mechanism in the state that the lowering material device is lowered. I could increase.

Next, an embodiment of the present invention will be described with reference to the drawings.

The rice transplanter of the present invention, as shown in FIG. 1, hydraulically presses the modeling device 5 to the rear of the passenger car body 4 equipped with a pair of left and right pairs of front and rear wheels (1) and (2) and a steering seat (3). Lifting is freely connected in parallel via the parallel four connection link mechanism 7 driven up and down by the cylinder (drive device) 6, and is comprised.

The seedling planting device 5 includes a planting part 10 and a planting portion 10 of the rice paddy surface T, which feeds the seedlings from the lower end of the transmission case 8, the base holder 9, which are powered by the vehicle body 4. The group of stationary floats 11 is provided, and the raising and lowering of the modeling material device 5 is adjusted according to the depth of the tilled ground G so that the float 11 always contacts the paddy water surface T appropriately.

The four parallel link link mechanisms 7 are connected to one upper link 7a whose front end is connected to the vehicle body frame, the left and right pair of lower links 7b and 7b, and side links connecting rear ends thereof. It is composed of (7c), the lower end boss 12 of the side link (7c) is supported by the support shaft 13, which is fixed to the front surface of the transmission case 8 of the modeling device (5) described above through and supported. It is comprised so that the modeling material 5 may roll around the front-rear axial center P of the support shaft 13. As shown in FIG.

Therefore, even if the vehicle body 4 is slightly inclined from side to side due to the unevenness of the tillage support base G, the modeling device 5 ground-supported on the rice field surface T via the float 11 is relatively relative to the vehicle body 4. It is rolled in, and the modeling material device 5 is always left and right parallel with the paddy water surface (T). The arm 14 protruding near the front end of the upper link 7a constituting the four parallel link links 7 and the proton rod 6a of the hydraulic cylinder 6 are elastic suspension mechanism 15. It is connected via.

The elastic suspension mechanism 15 is configured by externally enclosing the cylinder case 15a with respect to the piston rod 6a and sliding the compression coil spring 15b into the case. The hydraulic cylinder ( With respect to 6), four parallel linkage mechanisms 7 can elastically move up and down within a certain small range.

Therefore, even in the state where the hydraulic cylinder 6 is stretched and fixed, the modeling material 5 is allowed to move up and down a little by the elastic displacement of the elastic suspension mechanism 15 described above, and the vehicle body is formed by the unevenness of the arable ground G. Even if (4) is a little up and down movement, the modeling device (5) follows the rice paddy surface (T).

In the rice transplanter constructed as described above, the lowest descending position where the hydraulic cylinder 6 is shortest is set extremely low so that the seedling material 5 can be lowered to the rice field surface T even in the tilled ground G in shallow arable land. Moreover, the stroke of the hydraulic cylinder 6 is set so that it may be in the position which floated from the ground, even if the modeling material 5 was lowered on the hard and flat ground or the road surface.

In addition, in the present invention, the following configuration is added to the four connection link mechanisms 7 described above.

In other words, the front end of the rolling support shaft 13 penetrated to the boss 12 is fixed to the arm 16, which protrudes from side to side, and the prop 17 placed on the arm 16 from left and right in the upper surface ( On the upper end of 17), the modeling material 5 and the stopper 18 parallel to right and left are fixed across.

The stopper 18 has a length overlapping the upper surface of the left and right lower links 7b. When the modeling material 5 is in a position higher than the lowest position, as shown in FIG. 2, the stopper ( 18 is separated from the upper surface of the lower links 7b and 7b so that the rotation of the front and rear shaft center P of the stopper 18, that is, the rolling of the modeling device 5 is permitted. Moreover, the vertical movement of the modeling material 5 is also possible via the elastic suspension mechanism 15.

Then, when the modeling material 5 is lowered to the lowest position, the lower link 7b relatively swings upward with respect to the side links 7c of the four parallel linkage mechanisms 7 and the lower left and right links ( The upper surface of 7b) (7b) abuts against the stopper 18, whereby the rolling of the modeling material 5 is suppressed.

In the state where the left and right lower links 7b and 7b and the stopper 18 are in contact with each other, the relative fluctuations of the lower link 7b with respect to the side link 7c to the upper side of the lower link 7b are restrained by contact with each other. 7) The swinging of the lower part of the body becomes impossible again, and the elastic suspension mechanism 15 is elastically transformed so that the lowering is impossible.

That is, using the stopper 18 and the lower link 7b of the four link link mechanisms 7 in parallel, the fastening mechanism 19 which disables the rolling and elastic lowering when the model material device descends the most. ) Is configured.

In addition, the lower link (7b) (7b) is attached to the stopper bolts (20) and (20) opposite to both end faces of the arm (16) having a flat shape, the side when the modeling material (5) is raised to the highest position The lower link (7b) (7b) is relatively swinging downward relative to the link (7c), the arm 16 of the stopper bolts (20) and (20) of the planar shape abuts the upper surface, the arm of the planar arm Integral with (16), the rolling of the modeling material device 5 is suppressed.

In this way, the modeling material 5 is raised to the maximum to prevent the risk that the patterning material 5 rolls in response to vehicle body fluctuations during driving.
