BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0009]
As shown in FIGS. 1 and 2, a side-strip fertilizer type transplanter 1 shown as an example of a fertilizer application machine has a traveling machine body 2 supported by a front wheel 1a and a rear wheel 1b with a predetermined ground clearance. At the rear of the traveling machine body 2, there is provided a planting device 4 which is moved up and down by a lifting mechanism 3 comprising a hydraulic cylinder, a link and the like.
[0010]
The planting device 4 has a configuration similar to that of the conventional one, and the three floats 4a are grounded, and the planting portions (rotary type planting claws) 4b arranged on both sides of the floats 4a are placed on the seedling mounting table 4c. The mat seedlings are scraped and seedlings for 6 rows are planted.
[0011]
The body frame 6 of the traveling body 2 has an engine 1c mounted at the front, and a steering section 5 including a steering wheel 5a, a driver's seat step 5b, and a driver's seat 5c at the rear. Further, a transmission case 7 is disposed behind the engine 1c. A main frame 6a composed of two square pipes extends rearward from the transmission case 7 and a sub-frame 6b extends along the outside thereof. The two frames are connected to each other at a plurality of front and rear portions by a horizontal frame, so that the body frame 6 has a rigid frame structure.
[0012]
The driver's seat frame 6c supporting the driver's seat 5c has side frames 6d erected on the left and right sides, and the upper part thereof is connected by a horizontal frame 6e, so that the inside is deeply connected to the side-strip fertilizer transmission 8 described later. It is formed so as to be an installation space for the fertilizer transmission including the fertilizer transmission 9 and the like, and the two transmit the corresponding side-strip fertilizer feeding device 10 and deep fertilizer feeding device 10a.
[0013]
A plate-like step floor 6f is provided on the body frame 6 in front of the base of the driver's seat frame 6c to form a driver's seat step 5b.
[0014]
On the other hand, a fertilizer tank 11 is disposed on both sides of the engine 1c at the front of the traveling machine body 2, and the fertilizer tank 11 is covered like a fender by a front step 6g that allows an operator to walk.
[0015]
The left and right fertilizer tanks 11 are connected to the side-strip fertilizer feeding device 10 via a supply pipe 12 so that the fertilizer can be supplied. The front step 6g is displaced higher than the driver's seat step 5b, so that the fertilizer tank 11 can be arranged at a relatively high position, so that the transfer of fertilizer can be performed smoothly.
[0016]
The planting apparatus 4 is driven to change the speed of the paste-like fertilizer contained in the fertilizer tank 11 by a side-row fertilizer feeding device 10 driven by a side-row fertilizer transmission 8 and a deep-layer fertilizer transmission 9. The fertilizer is fed backward by the fertilizer application feeder 10a for each fertilizer strip, and the fed fertilizer is fed via the fertilizer feed pipe 13 and the indicator 15 to the side strip nozzle 16 provided on both sides of the float 4a; A fertilizer apparatus for applying fertilizer toward the ground from a fertilizer nozzle such as a deep-layer nozzle 17 provided to protrude downward from the center of the 4a is configured in the following manner.
[0017]
It should be noted that the side streak nozzle 16 is adapted to apply fertilizer to a shallow depth near the seedlings planted at the planting portions 4b on both sides of the float 4a. Further, the deep layer nozzle 17 is for applying fertilizer to a deep depth in the middle of the planted seedling.
[0018]
Next, a power transmission system of the transplanter 1 and the implanting device 4 will be described with reference to FIG.
[0019]
The power from the engine 1c drives the front wheels 1a and the rear wheels 1b so as to be able to change the traveling speed via a transmission mechanism in the transmission case 7 of the traveling unit transmission system. The transmission case 7 is input to a transmission mechanism in a rear wheel support case 19 by a rear wheel drive shaft 18 to drive the left and right rear wheels 1b. Further, a transmission input shaft 20 provided on the lower side of the transmission of the traveling unit transmission system extends rearward from the transmission case 7 and protrudes from the side-line fertilization transmission 8 via the connecting shaft 21. It is connected to the shaft 22.
[0020]
As shown in FIGS. 4 to 6, the side-strip fertilizer transmission 8 includes the above-mentioned transmission input shaft 22, the second shaft 23, the third shaft (intermediate shaft) 25, and the delivery output shaft 26 in the case 8a in the front-rear direction. The shaft is supported in parallel.
[0021]
The second shaft 23 is operatively connected to a deep shift input shaft 27 of the deep fertilizer transmission 9 described later by a chain transmission mechanism including sprockets 28 and 28a and a chain 29, and is installed on the shift input shaft 22 side. Power is turned on and off by the input clutch mechanism 30.
[0022]
The input clutch mechanism 30 slides the clutch body 32 by operating an input clutch shifter 8b (FIG. 5) that performs an on / off operation in conjunction with a planting clutch pivotally supported by the case 8a. By engaging and disengaging the clutch gear 33 supported by the free-rotating shaft, the second shaft 23 is driven via the input gear 35 engaged with the clutch gear 33, and the side-line fertilizer transmission 8 is driven. And the power input shaft 27 of the deep fertilizer transmission 9 can be simultaneously turned on and off.
[0023]
Further, the side-strip fertilizer transmission 8 operates the side-street main shift lever 31 and the side-street sub-shift lever 36 pivotally supported by the case 8a to move the second shaft gear 37, the intermediate shaft gear 38, and the delivery shaft gear 39. The combination of the speed change combination meshing, the number of rotations of the delivery output shaft 26 is changed to a plurality of stages, and the fertilization amount delivery adjustment is performed by applying fertilization adapted to various conditions such as the type of fertilizer and the condition of the field, the type of seedling, and the running speed of the machine. So they can do it.
[0024]
In addition, since the speed change input shaft 22 of the side-strip fertilizer transmission 8 is adapted to be input-transmitted from the transmission case 7 on the traveling unit transmission system side during the fertilizer application control, the traveling speed (vehicle speed) of the machine body is reduced. Coordinated fertilization can be performed.
[0025]
Next, the side-strip fertilizer feeding device 10 will be described with reference to FIGS.
[0026]
The side-strain fertilizer feeding device 10 has a pump case 10c with six pump shafts 40 pivotally supported at substantially equal intervals in two upper and lower stages, and a connecting chain having substantially the same length at a shaft end protruding forward. A sprocket 42 for winding 41 is provided, and a pump shaft 40 located at the center of the upper stage is configured to be transmitted from a delivery output shaft 26 (FIG. 5) by a transmission chain 43.
[0027]
Further, a pump cover 46 which is detachably attached to the rear surface of the pump case 10c via a triangular mounting seat 45 and covers the pump shaft 40 is arranged in parallel with the mounting seats 45 alternately arranged vertically (FIG. 8). By minimizing the distances a and b and making them the same length, care is taken not to increase the height when a plurality of pump cases 10a are arranged.
[0028]
In this way, the height of the side fertilizer feeding device 10 in the vertical direction is made as small as possible to achieve miniaturization, and a simple structure is achieved while sharing the parts using the connecting chain 41 having the same length. The configuration is such that the side fertilizer feeding device 10 having the configuration can be provided.
[0029]
Further, the side-strip fertilizer feeding device 10 configured as described above does not greatly protrude downward even when it is mounted using the “space” at the bottom of the body frame 6 as shown in FIG. There are advantages such as not lowering the minimum ground clearance.
[0030]
Although not shown in detail in FIG. 3, as shown in FIG. 3, the above-mentioned deep fertilizer feeding device 10a driven from the feeding output shaft 47 of the deep fertilizer transmission 9 via the transmission chains 48, 49 and the like is also a lateral member. The fertilizer feeding device 10 has substantially the same configuration as that of the fertilizer feeding device 10 and is disposed on the side of the side-strip fertilizer feeding device 10 with the supply pipe 12 interposed therebetween. 13 (FIG. 2). By operating the deep main transmission lever 51 (FIG. 5) and the deep sub transmission lever 51a, the deep fertilizer transmission 9 can be operated by the same transmission means as the lateral fertilizer transmission 8, so that the deep transmission input shaft 27 can be used. , The feed output shaft 47 is rotated at a variable speed.
[0031]
In the power transmission system as described above, as shown in the figure, the transmission device 8 for lateral fertilization and the transmission device 9 for deep fertilization use a space in the driver's seat frame 6c in a compact manner and have easy operability. Well configured.
[0032]
That is, as shown in FIGS. 2 and 5, the side-strip fertilizer transmission 8 and the deep-layer fertilizer transmission 9 are arranged side by side with the respective levers facing upward, and are attached to the body frame 6. In the meantime, the side-row fertilizer transmission 8 is stably fixed on the body frame 6 by an attachment base 52 which also serves as a cover member that covers the bottom side from below. Further, the side fertilizer feeding device 10 and the deep fertilizer feeding device 10a, which are transmitted from the two as described above, are fixed to the lower part of the body frame 6 in parallel in the left-right direction, and are compactly arranged close to each other to simplify the transmission structure. become.
[0033]
Further, since the side-strip fertilizer feeding device 10 and the deep-layer fertilizer feeding device 10a are provided at a position slightly lower than the bottom portion of the fertilizer tank 11 installed below the step supporting surface 6g, the fertilizer is supplied via the supply pipe 12. It can be supplied smoothly.
[0034]
Further, the side-line fertilizer transmission 8 and the deep-layer fertilizer transmission 9 operate the side-line main shift lever 31 and the side-line sub-shift lever 36 and the deep-layer main shift lever 51 and the deep-layer sub-shift lever 51a in the driver's seat step. It can be performed intensively at a relatively high position on 5b.
[0035]
Further, the transmission device 8 for lateral fertilization and the transmission device 9 for deep fertilization are not provided separately from the abdomen of the body as in the conventional device, but below the driver seat 5c higher than the driver step 5b and above the main frame 6a. And the fertilizer feeding device 10 and the deep fertilizer feeding device 10a are installed in the abdomen of the body below the main frame 6a, so that the fertilizing transmissions 8, 9 and the fertilizer feeding device 10, 10a are balanced in consideration of the stability of the center of gravity. It can be installed in parallel well, and the running performance can be improved without lowering the minimum ground clearance.
[0036]
In such an implanting machine 1, after operating the side-line transmission levers 31, 36 and the deep-layer transmission levers 51, 51a to desired transmission positions corresponding to the above-described various conditions, an implanting clutch (not shown) is engaged. Then, the input clutch shifter 8b is linked to the on state, and the traveling machine body 2 travels at the predetermined vehicle speed set in the transmission case 7 while the transmission input shaft 20 is branched from the fertilizer transmission shaft 20 branched from the traveling transmission system of the transmission case 7. 22 is driven, the second shaft 23 is driven by the input operation of the input clutch mechanism 30, the feed output shaft 26 is rotated at a variable speed, and the side fertilizer feeding device 10 is set to rotate, and the fertilizer commensurate with this rotation is fed. Fertilizer is applied underground from the row nozzle 16 and simultaneous fertilization and planting work is performed.
[0037]
Since the transmission to the deep fertilizer transmission 9 is branched from the upstream side of the transmission mechanism of the side fertilizer transmission 8, the side fertilizer feeder 10 and the deep fertilizer feeder 10a are independently shifted. Even if the amount of fertilization by the side fertilizer feeding device 10 is changed, the amount of fertilization by the deep fertilizer feeding device 10a does not change, so that it is not necessary to readjust the amount of fertilization by the deep fertilizer feeding device 10a.
[0038]
Also, at this time, the side fertilizer feeding device 10 drives the input rotation of the speed change input shaft 22 from the second shaft 23 transmitted through the input clutch mechanism 30, so that the side fertilizer feeding device 10 and the deep fertilizer feeding device 10a. Can be simultaneously turned on and off by the input clutch mechanism 30.
[0039]
Further, by operating each of the side sub-transmission lever 36 and the deep sub-transmission lever 51a to the neutral position, the transmission to the respective feeding devices is cut off, and the power can be turned off independently.
[0040]

It is possible to unify the fertilization amount adjustment work per unit and smoothly perform the fertilization amount adjustment work without causing confusion.
[0042]
Further, the transmission of the side fertilizer feeding device 10 is performed from the fertilizer transmission shaft 20 via the side fertilizer application transmission 8, and the transmission of the deep fertilizer feeding device 10 a is performed on the side of the transmission input shaft 22 of the side fertilizer transmission 8. , The transmission from the fertilizer transmission shaft 20 to the lateral fertilizer feeding device 10 and the deep fertilizer feeding device 10a by the speed change input shaft 22 is made simple, and at the same time the vehicle speed is linked. Fertilizer can be applied from the row nozzle 16 and the deep layer nozzle 17.
[0043]
