The seeding transplant machine 1 of present embodiment 1 has structure as above, below its effect is described.When turning round, seeding transplant machine 1 carries out travelling, loading in the plantation operation of the seedling of seedling mounting table 65 of running vehicle body 2 by the power being produced by engine 20.Wherein, plantation operation in, rotating shaft with become left and right directions towards making cultivation device 61 integral-rotations, implant bar 62 simultaneously and also rotate, thus the seedling loading in seedling mounting table 65 is planted in farmland gradually according to each row.Plantation when operation, is travelled cultivation device 61 actions on one side by such, thereby is planted seedling in multirow ground in farmland by running vehicle body 2.
Carry out as described above the seedling plantation portion 60 of the plantation of seedling, carry out work and carry out as required lifting by hydraulic lifting cylinder 76.For example, operator operates plantation elevating lever, or running vehicle body 2 arrives the end in farmland in plantation operation, and when operator's steering wheel rotation 52 etc., seedling plantation portion 60 carries out lifting.
In addition, plantation operation is on one side travelled and is carried out on one side by running vehicle body 2 in farmland, but makes driving force that running vehicle body 2 travels by utilizing the power being produced by engine 20 mainly to make trailing wheel 10 rotate to produce.Because the outer peripheral face of the wheel rim 13 having at left and right trailing wheel 10,10 is provided with lug 14, therefore, in the time that left and right trailing wheel 10,10 has rotated, lug 14 enters farmland while rotates.Thus, trailing wheel 10 can not dally and rotates and produce driving force at farmland face, and running vehicle body 2 travels by the driving force being produced by this trailing wheel 10.
This trailing wheel 10 between left and right every be configured to than front-wheel 5 between left and right every narrow, when therefore running vehicle body 2 travels, left and right trailing wheel 10,10 is moving on the face of farmland from the different position of passing through, position of passing through of left and right front-wheel 5,5.Thus, can prevent that left and right trailing wheel 10,10 from entering the rut that passes through to form due to left and right front- wheel 5,5, therefore can prevent that body from entering farmland deeper, running vehicle body 2 can stably travel in farmland.
In addition, be equipped with left and right auxiliary wheel 100,100 at the trailing wheel 10,10 of left and right, in the time of 10,10 rotation of left and right trailing wheel, left and right auxiliary wheel 100,100 is also followed the rotation of left and right trailing wheel 10,10 and is rotated.In addition, on the auxiliary wheel 100,100 of left and right, same with left and right trailing wheel 10,10, be provided with lug 104 for auxiliary wheel at auxiliary wheel with the outer peripheral face of wheel rim 103, therefore in the time of 100,100 rotation of left and right auxiliary wheel, auxiliary wheel enters farmland with lug 104 while rotates.Thus, can make left and right auxiliary wheel 100,100 not dally and rotate and produce driving force at farmland face, the driving force that therefore running vehicle body 2 can produce by left and right auxiliary wheel 100,100 be travelled.
Now, the auxiliary wheel of the lug 14 of left and right trailing wheel 10,10 and left and right auxiliary wheel 100,100 is upwards arranged on identical position with lug 104 in week, therefore in the time of left and right trailing wheel 10,10 and 100,100 rotation of left and right auxiliary wheel, the auxiliary wheel of the lug 14 of left and right trailing wheel 10,10 and left and right auxiliary wheel 100,100 is used lug 104 ground connection simultaneously.
Thus, the generation moment that can make the driving force of left and right trailing wheel 10,10 and left and right auxiliary wheel 100,100 is mutually in the same time, therefore can make it produce larger driving force, and running vehicle body 2 can travel by this larger driving force.
On the other hand, the auxiliary wheel of the spoke 11 of left and right trailing wheel 10,10 and left and right auxiliary wheel 100,100 is upwards arranged on different positions with spoke 101 in week, therefore the earth in farmland can not spread all over the spoke 11 of left and right trailing wheel 10,10 and auxiliary wheel spoke 101 ground of left and right auxiliary wheel 100,100 adhere to larger piece, but is attached to respectively spoke 11 and auxiliary wheel with on spoke 101.
Thus, left and right trailing wheel 10,10 and left and right auxiliary wheel 100,100 when rotated, can make the auxiliary wheel spoke 101 of left and right trailing wheel 10,10 spokes 11 and left and right auxiliary wheel 100,100 can not take up the earth in farmland larger piece rotate.
In addition, be provided with buoyancy aid 81 in the bottom of seedling mounting table 65 at the rear portion that is provided to running vehicle body 2, in the time that running vehicle body 2 travels, this buoyancy aid 81 slides smooth farmland face on one side and travels on one side on the face of farmland.In the time that running vehicle body 2 travels, enter farmland face due to the lug 14 of left and right trailing wheel 10,10 and the auxiliary wheel of left and right auxiliary wheel 100,100 with lug 104 while travel, therefore on farmland, produce concavo-convex, but owing to being provided with this buoyancy aid 81 at the rear of left and right trailing wheel 10,10 and left and right auxiliary wheel 100,100, therefore the concavo-convex of farmland flattened by buoyancy aid 81.
Now, be disposed in than left and right trailing wheel 10,10 and more lean on the outboard end of the auxiliary wheel lug 104 of the left and right auxiliary wheel 100,100 in body outside to be positioned at the left and right width of the buoyancy aid 81 of left and right directions, the concavo-convex of farmland that therefore auxiliary wheel of the lug 14 of left and right trailing wheel 10,10 and left and right auxiliary wheel 100,100 causes with lug 104 flattened by buoyancy aid 81.Thus, farmland face is flattened, and can on the smooth farmland face after smooth, plant seedling.
In addition, when running vehicle body 2 travels,, rotate centered by central shaft 128 by yaw frame 120 during because of concavo-convex the changing in farmland at the height of left and right trailing wheel 10,10, left and right trailing wheel 10,10 can make the height change of above-below direction together with left and right rear wheel gear case 23,23.
In addition, be provided with seedling frame 90 for subsequent use in the position of the partially forward end of running vehicle body 2, but this seedling frame 90 for subsequent use is arranged on the included position of outboard end from bottom pedal 40 in the end of left and right directions.Thus, operator can notice that seedling frame for subsequent use 90 and outside barrier etc. travel contiguously.
The action of the cultivation device 61 on one side carry out the plantation operation of seedling to travelling on one side in farmland time describes, and with regard to cultivation device 61, when cultivation device 61 self rotates, the implantation bar 62 that forms cultivation device 61 rotates.Thus, implant bar 62 and capture and keep being positioned in the seedling in seedling mounting table 65, the seedling of maintenance is planted in farmland.
Specifically, implant bar 62 in the time capturing and keep being positioned in the seedling in seedling mounting table 65, releasing fork 135 becomes the state of contraction, keeps seedling at 132 of plantation pawls getting seedling finger 131.Release fork 135 by cultivation device 61 and implant bar 62 and rotate, stretching out during to farmland side shifting by plantation pawl 132, release the seedling keeping between plantation pawl 132.Thus, the seedling being kept by plantation pawl 132 is planted in farmland.
In addition, under the state stopping at the engine 20 of the seeding transplant machine 1 of present embodiment 1, pilot engine 20 o'clock, preferably to functional unit 35(with reference to Figure 13, Figure 14) operate, the transmit mode of switching the power of transmission endless belt 30 is also started.Particularly, piloting engine 20 o'clock, the insertions such as bar are being formed to the hole portion 43 of side pedal 42, pressing the functional unit 35 of the below that is positioned at hole portion 43 downwards.
Thus, even rotate at the 20 o'clock engine belt wheels 32 of piloting engine, engine belt wheel 32 also dallies, therefore transferring power not between engine belt wheel 32 and transmission endless belt 30.Namely, functional unit 35 is being operated, when switching device shifter 31 is switched between engine 20 and Hyaulic infinite variable speed mechanism 26 not to the non-drive state of transferring power, transferring power not between engine belt wheel 32 and transmission endless belt 30.
As mentioned above, by become non-drive state between engine 20 and Hyaulic infinite variable speed mechanism 26, thus the resistance force diminishes of piloting engine 20 o'clock, therefore engine 20 easily starts.
Piloting engine 20 o'clock, preferably the state of operation, starting by the start-up function of carrying out engine 20 at operating portion 50 functional unit 35 having been carried out from the hole portion 43 of side pedal 42.Particularly, in the time of the cold start of the engine 20 of cold zone, because the mobility of lubricating oil is low etc., engine 20 is difficult to starting, therefore in the time of the engine 20 of this state of starting, by functional unit 35 is operated, start after switching device shifter 31 is switched to non-drive state, thereby can easily make engine 20 start.
If engine 20 has started, remove the power that functional unit 35 is operated.Thus, switching device shifter 31 is to transmission endless belt 30 application of forces, makes the tension force of transmission endless belt 30 become large, therefore becomes from engine 20 state to Hyaulic infinite variable speed mechanism 26 transmission driving forces via transmission endless belt 30.Thus, Hyaulic infinite variable speed mechanism 26 utilizes the driving force of transmitting from engine 20 and works, and becomes the state that seeding transplant machine 1 can turn round.
In addition, piloting engine 20 o'clock, in the time there is multiple operator, also can a people from the side of side pedal 42, functional unit 35 be operated, switching device shifter 31 is being switched under the state of non-drive state, another operator carries out the start-up function of engine 20 at operating portion 50.
The seeding transplant machine 1 of above embodiment 1 can regulate the interval of the trailing wheel 10,10 of left and right auxiliary wheel 100,100 and left and right, the farmland condition such as mobility by corresponding earth regulates the interval of left and right trailing wheel 10,10 and left and right auxiliary wheel 100,100 thus, thereby can prevent that left and right auxiliary wheel 100,100 and left and right trailing wheel 10,10 from taking away earth.Thus, farmland face generation can be suppressed at concavo-convex, planarization can be improved.
