Referring to Figure 35, an embodiment of setting and seedling planting control to seedling planting condition is illustrated. Rice transplanter 1 is constituted are as follows: mode standard corresponding with the nursery pad of standard type nursery and the rice shoot grown can be selected close Spend close stand mode corresponding to the nursery pad of the high density nursery also higher than the nursery pad of standard type nursery.Transplant job controller 500 are stored in storage device 501: the control program of mode standard and the control program of close stand mode.Using high It is assembled when the nursery pad of density nursery: taking-up mask 226a, the plant pawl 30a and release piece 234a of high density nursery, It is assembled when being padded using the nursery of standard type nursery: taking-up mask 226b, the plant pawl 30b and release piece of standard type nursery 234b (referring to Figure 30 and Figure 31).
If passing through the operation of Item Selector 502, and in the items selection picture 523 of rice shoot mode (referring to Figure 34) In, once selection close stand mode (step S1:Yes), then read in the control program (step S2) of close stand mode.In close stand mode Under, in the items selection picture 523 and setting screen 524 of seedling taking amount (longitudinal seedling taking amount), longitudinal seedling taking amount is adjusted Range is restricted to the prescribed limit (step S3) of lower limit side.That is, compared with when the plant of the nursery pad of standard type nursery, in height When the plant of the nursery pad of density nursery, actuator mechanism 181 (referring to Fig.1 7) are adjusted to based on seedling taking by electrical control The movable range of the seedling taking regulating member 137 of implementation is limited, and the adjustable extent of longitudinal seedling taking amount is limited to The prescribed limit of lower limit side.In this embodiment, under mode standard, the adjustable extent of longitudinal seedling taking amount is 8~17mm (1 scale is 1mm, 10 scales), in contrast, as shown in figure 34, under close stand mode, by the adjustable of longitudinal seedling taking amount Range 525 is limited to 8~13mm (6 scales of lower limit side).When using the rice transplanting operation of the nursery pad of high density nursery, such as Fruit operator has selected close stand mode, then can be suppressed to longitudinal seedling taking amount forgetting the setting to longitudinal seedling taking amount Therefore 13mm is hereinafter, can prevent: the number of every 1 plant of rice shoot becomes useless consumption that is extremely more and leading to rice shoot, so as to Rice transplanting operation appropriate is enough carried out, and can reduce the burden of operator relevant to the setting of longitudinal seedling taking amount.
In addition, as described above, about the intermittent driving based on rice shoot length feed band 155 (referring to Fig. 9 and Figure 12) Rice shoot longitudinal direction supply amount links seedling taking double-linked cam 138 (referring to Fig. 8) and inverted cam 153 by linkage wire rod 156 Come, so that rice shoot longitudinal direction supply amount also correspondingly changes with the variation of longitudinal seedling taking amount.Therefore, when using highly dense When spending the nursery pad of nursery, longitudinal seedling taking amount is being set as less feelings compared with when the nursery of standard type nursery being used to pad Under condition, rice shoot longitudinal direction supply amount is also reduced, and is longitudinally supplied to carry out rice shoot appropriate corresponding with longitudinal seedling taking amount.By This can reduce nursery pad when padding using the nursery of high density nursery compared with when the nursery of standard type nursery being used to pad Depletion rate, number is padded in nursery needed for capable of reducing the rice transplanting operation of per unit area, and can reduce to seedling mounting table The number of 29 supplement nursery pads, reduction, operator, operation auxiliary so as to the time needed for realizing seedling planting operation The reduction of the labour of person.
Next, the depth of planting control to the rice shoot in seedling planting operation under close stand mode is illustrated.It is selecting When close stand mode, when selection criteria mode compared with, to 39 (liquid of hydraulic cylinder in a manner of deepening the depth of planting of rice shoot Pressure lifting control mechanism) elevating control be corrected.When by the operation to operation bar 16 make seedling-transplanting device 23 decline And start when seedling planting operation (step S4:Yes), pass through the behaviour to lifting switching solenoid valve 99 and electromagnetic switching valve 101 Make and drives lifting cylinder 39 to decline side.Up to the heave sensor value V of heave sensor 325 and as hydraulic sensitivity Until the target value V1 of (target tilt angle of central float 32a) consistent (tilt angle of central float 32a is constant), utilize Lifting cylinder 39 and decline control is carried out to seedling-transplanting device 23, the target depth of planting hereafter is maintained to constant mode (V =V1) carry out seedling-transplanting device 23 elevating control.
It in seedling planting operation, reads in: hydraulic sensitivity setting value, the lifting sensing of hydraulic sensitivity setting apparatus 502 The heave sensor value V of device 325 and the vehicle speed sensor value (step S5:Yes) of vehicle speed sensor, relative to hydraulic sensitive The hydraulic sensitivity setting value of setting apparatus 502 is spent, and by the hydraulic sensitivity (sensitivity) of hydraulic cylinder 39 to blunt side (float That side that the front of 32a rises) correction (step S6), based on Sensitirity va1ue after heave sensor value, correction and speed sensing Device value, and (step S7) is calculated to the target value V1 as hydraulic sensitivity.Here, the travel speed of travel machine body 2 is got over Fastly, float 32 more shows the trend towards front upper place, and the deflection of float 32 is increased, on the other hand, travel machine body 2 Travel speed it is slower, float 32 more shows the trend towards front lower place, and the deflection of float 32 is reduced, therefore, In above-mentioned steps S6, according to vehicle speed sensor value so that the mode of seedling planting constant depth, carries out target value V1 It calculates.
So that heave sensor value V and the consistent mode of target value V1, carry out elevating control (step to seedling-transplanting device 23 Rapid S8).It when heave sensor value V is consistent with target value V1, is acted hydraulic cylinder 39, and makes seedling-transplanting device 23 Lifting stop.When heave sensor value V is less than target value V1, electromagnetic opening and closing valve 101 is connected to open position 101a, and And lifting switching valve 99 is connected to drain position 99b and lifting cylinder 39 is made to carry out contractive action, decline seedling-transplanting device 23, So that heave sensor value V is consistent with target value V1.When heave sensor value V is greater than target value V1, by electromagnetic opening and closing valve 101 are connected to open position 101a, and lifting switching valve 99 is connected to supply position 99a, increase seedling-transplanting device 23, with So that heave sensor value V is consistent with target value V1.
On the other hand, if in the items selection picture 523 (referring to Figure 34) of rice shoot mode selection criteria mode (step S1:No), then the control program (step S11) of mode standard is read in.Under mode standard, in seedling taking amount (longitudinal seedling taking amount) Items selection picture 523 and setting screen 524 in, not to the adjustable extent of longitudinal seedling taking amount with the side of electrical control Formula is limited, and can be selected in the range of 8~17mm (1 scale is 1mm, 10 scales).
Next, start the plant operation of rice shoot under mode standard, (step when in the plant operation in rice shoot S12:Yes), read in: the heave sensor of the hydraulic sensitivity setting value of hydraulic sensitivity setting apparatus 502, heave sensor 325 The vehicle speed sensor value (step S13:Yes) of value V and vehicle speed sensor 505, to the target value V1 as hydraulic sensitivity into Row calculates (step S14).Here, under mode standard, hydraulic sensitivity is set unlike step S6 when close stand mode Value is corrected.Moreover, being controlled (step to seedling-transplanting device 23 in a manner of keeping heave sensor value V and target value V1 consistent Rapid S15).
In this embodiment, it when having selected close stand mode, as above-mentioned steps S3, is set relative to hydraulic sensitivity Determine the hydraulic sensitivity setting value of device 502, and the hydraulic sensitivity of hydraulic cylinder 39 is corrected to blunt side, with selection criteria mould It is compared when formula, to the elevating control of hydraulic cylinder 39 (hydraulic lifting control mechanism) in a manner of deepening the depth of planting of rice shoot It is corrected.In the rice transplanting operation using the nursery pad of high density nursery, compared with when the nursery of standard type nursery being used to pad, Plant pawl 30 carries out that the area that takes of rake is smaller, and therefore, the rice shoot transplanted to field is easy to float to nursery pad.Therefore, with selection It is compared when mode standard corresponding to the nursery pad of standard type nursery, is selecting the nursery pad corresponding to high density nursery When close stand mode, automatically the elevating control of hydraulic cylinder 39 is corrected in a manner of deepening the depth of planting of rice shoot, Thus, it is possible to prevent rice shoot from floating, and it can reduce the burden of the relevant operator of setting to the depth of planting of rice shoot.
In addition, the sensor values of Surface testing sensor 334 can be used in above-mentioned steps S7 and S14, so that in The mode that the deflection of centre float 32a reaches steady state value is corrected the target value V1 of hydraulic sensitivity, so that rice shoot The depth of planting it is constant.According to the sensor values for the Surface testing sensor 334 that the actual height to field surface is detected, And the deflection of central float 32a is calculated, with the mode that keeps deflection constant by the target value V1 of hydraulic sensitivity to Blunt side (that side that the front of float 32a rises) or sensitive side (that side of the front decline of float 32a) correction.Here, When selecting close stand mode, spirit after the correction after correcting hydraulic sensitivity setting value to blunt side in above-mentioned steps S6 is used Sensitivity value, come carry out hydraulic sensitivity target value V1 calculating and correction.
Referring to Figure 36, the other embodiments of setting and seedling planting control to seedling planting condition are illustrated. In this embodiment, include: replacing the above-mentioned steps S6 in the embodiment illustrated referring to Figure 35 (when selection close stand mode) And the step S3-1 that the position of float 32 is corrected in a manner of deepening the depth of planting of rice shoot.In step S3-1, For the setting value (referring to Figure 34) of the depth of planting set by the operation to Item Selector 502, so that the cultivation of rice shoot The mode for planting depth down is corrected depth of planting setting value.In this embodiment, it is adjusted by the depth of planting electronic The driving of machine 174 (referring to Fig.1 5), and depth of planting regulating member 122 and correcting value are rotated to correspondingly front, thus 121 side of depth of planting adjustment axis that is positioned against of float 32 is corrected.Plant pawl 30 when seedling planting operation as a result, Overhang (the distance between front end and 32 bottom surface of float of plant pawl 30) increases, and the depth of planting of rice shoot is deepened.In this way, Under close stand mode using the nursery pad of high density nursery, automatically to float 32 in a manner of deepening the depth of planting of rice shoot Position be corrected, nursery pad is carried out to prevent rice shoot from floating the area that takes of rake reduces even if transplanting pawl 30 as a result, And it can reduce the burden of the relevant operator of setting to the depth of planting of rice shoot.
