[0003]

[Problems to be solved by the device]

 The above-mentioned conventional filter used for liquid supply work has a minimum mesh size corresponding to it, in order to prevent clogging of small nozzle holes for spraying chemicals such as disinfectant and prevent its safety. It is installed in each tank. Therefore, the filter with the above-mentioned small scale works well because it can remove even small foreign substances when water for diluting and dissolving chemicals is used, such as river water. When filtering liquid fertilizers, the filtration speed becomes slow and it takes a long time for the supply work, and the slightly larger granular fertilizers and organic fibers contained in the fertilizers are not filtered and remain on the filter. There are drawbacks. Therefore, there is a problem that a complicated supply work such as crushing and filtering the above residue on a filter and separately preparing and using a wire net dedicated to fluid fertilizer are required. In view of the above, the present invention solves the above-mentioned problems of the prior art by connecting a plurality of tanks installed in a fertilizer application machine so as to join the tanks, and by additionally providing a filter having a different mesh to the tank, The present invention aims to provide a liquid storage tank in a fertilizer application machine, which can efficiently and appropriately supply the liquid stored in the fertilizer.

A front wheel stay 9 is vertically provided so as to vertically support a pair of left and right front wheels 8 via an adjusting handle 9a. Further, the attachment frame (extinguishing frame) 10 of the extermination part S has a supporting arm 10a and a lower mounting piece 10b projectingly provided, and the supporting arm 10a is supported by a spindle 10c in the middle of the fertilizing frame 5a. The lower attachment piece 10b is integrally framed with the fertilization frame 5a. The fixing piece 9c is detachably fastened to the fixing piece 9b projecting from the front wheel stay 9 described above so that the lower attachment piece 10b is fixed in the solid line control work posture. ing. The pest control frame 10 is mounted so that it can be switched to the storage posture shown by the dotted line by tilting in the direction of the arrow in FIG. 1 with the support shaft 10c as the fulcrum by releasing the fixing tool 9c. Reference numeral 10d is a hook-shaped fixing tool for fixing the pest control frame 10 along the machine body when it is tilted.

The pest control frame 10 is a substantially rectangular frame body on the front, and a plurality of mounting holes 10e for mounting beams (mounting members) 15 are provided at predetermined intervals in the longitudinal direction (vertical direction) thereof. Further, both wings of the beam 15 are provided with mounting arms (mounting members) 15a, 15b which are foldable upward and pivotally fixed via a pivot 15 ', and the mounting arms 15a, 15b are respectively bendable and oriented. A flexible injection pipe 17 having a plurality of variable spray nozzles (nozzles) 16 is straightened in a state in which a midway portion in the longitudinal direction is fixed as shown by a chain line in FIG. 6 and also has an arch shape as shown by a solid line. It is installed so that it can be flexibly deformed. The above-mentioned pest control frame 10 is sandwiched between the beam 15 and the pressing plate 18 from the front and back, and a height adjusting knob 19 is screwed between the both, and the beam 15 is mounted at an appropriate height position by tightening and loosening the knob 19. It is set in the hole 10e so that the mounting height of the beam 15 can be easily adjusted and fixed.

Reference numeral 11 denotes an operating lever which is provided on the handle H portion and which rotates the mounting arms 15a and 15b up and down by a hand operation. The mounting arms 15a and 15b are pivoted about a pivot 15 'through the wire 12. As a result, the folds can be turned upward individually or simultaneously. Reference numeral 13 is a tension spring for supporting and supporting the mounting arms 15a and 15b so as to stably maintain the respective operating postures. Reference numeral 13a is a stopper that receives the projecting work posture of the mounting arms 15a and 15b, and is fixed to the lower ends of both ends of the beam 15 described above. Reference numeral 15f is an attachment piece provided on the attachment arms 15a and 15b in an appropriate number, and a vinyl cover is attached to the attachment piece 15f.

Above the traveling machine body 1 (upper position between the rear wheel 2 and the front wheel 8 in the embodiment), liquid or pasty liquid fertilizer, or chemical liquid (insecticide, bactericide, herbicide, etc.) Two tanks 20 that selectively store liquids such as the above are mounted. The tanks 20 are arranged side by side symmetrically on the left and right of the main frame 5 to form a pair, and a supply port 20b having a large-diameter lid 20a is formed on the upper part thereof as shown in FIG. There are provided bowl-shaped filters 20c and 20d made of metal mesh, which are detachably fitted and retained in the mouth 20b. The filter 20c installed in the one tank 20 has a larger mesh (about 2 mm square) than the filter 20d installed in the other tank 20. As the mesh M, for example, paste-like fluid fertilizer is used. In addition to providing a filter body suitable for filtering, the other filter 20d dissolves the disinfectant discharged from the spray nozzle 16 having a small nozzle, so that the mesh m (0. About 8 mm square).

Reference numeral 21 is a stirrer for stirring the contents in the tank 20, and auxiliary tanks 22, 22 for storing washing water are mounted in front of the tank 20 and above the front wheel 8. The cleaning water stored in the auxiliary tank 22 is jetted into the tank 20 by using the pump 27 described later at the end of the management work such as fertilization work or prevention work to wash the fertilizer and the chemical liquid in the respective flow passages. To be able to carry out easily.

By the way, in the soil fertilizer application section F, the pair of left and right rod-shaped fertilizer application nozzles 23, 23a supported by the upper and lower crankshafts 24, 24a are deformed circularly by changing the phase by 180 degrees to the left and right, so that the machine body can run. Along with this, when the fertilizer application nozzles 23, 23a are moved from the front to the rear, the lower end discharge port side is pierced into the soil to apply fertilizer (point injection fertilizer). That is, as shown in FIGS. 1 and 3, the chain cases 7 and 7a respectively support two upper and lower crankshafts 24 and 24a which rotate synchronously by chain transmission, and the left and right crankshafts 24 and 24a respectively. The fertilizer application nozzles 23 and 23a are connected by crank arms 25 and 25a so as to perform a circular deformation motion in the vertical direction. The discharge ports of the fertilizer application nozzles 23 and 23a discharge the paste-like fertilizer, and therefore are larger than the discharge ports of the spray nozzle 16 for pest control.

Reference numeral 27 denotes a pump located below the tank 20 and fixed on the pump mounting base 5b. The pump 27 is connected to the engine E via a transmission mechanism M as shown in FIGS. The suction port 27a side of 27 can be switched between the tank 20 and the auxiliary tank 22 via a switching valve 28 and pipes 29a, 29b, 29c, and the discharge port 27b side can be connected to an accumulator 30, 30a described later. Each is connected via a pipe. The pump 27 shown in the embodiment employs a double piston pump in which two right and left plunger type pistons K reciprocate to perform suction and discharge.

The drive shaft (pump shaft) 27 ′ of the pump 27 has an eccentric cam portion similar to, for example, a crank shaft of an engine, and the left and right pistons k incorporated in the pump 27 by rotation of the pump shaft 27 ′. Are configured to reciprocate in opposite directions with a predetermined stroke. As a result, in the case of fertilizing work in which the valves 55 and 55a provided on the steering handle are opened by the respective lever operations and the valves 57 and 57a are closed, the suction port 27a is passed through the pipes 29a and 29c. The fertilizer in the tank 20 sucked into the pump 27 is fed and accumulated from the discharge port 27b to the pair of left and right accumulators 30 and 30a via the pipes 30 'and 30'a, respectively, and the accumulators 30 and 30a from the accumulators 30 and 30a. It is pressure-fed to the fertilizer application nozzles 23, 23a side via the intermittent valves 31, 31a so that the fertilizer is applied by pouring into the soil.

Then, in the case of the control work in which the valves 55 and 55a are closed and the valves 57 and 57a are opened, the chemical liquid in the tank 20 sucked into the pump 27 from the suction port 27a in the same manner as described above. Is fed from the discharge port 27b to the accumulators 30 and 30a, respectively, and is then pressure-fed to the injection pipe 17 side via the pipes 32 and 32a and continuously sprayed from the spray nozzle 16 to the crop T in the field. I am trying. The switching of the pump drive state corresponding to the fertilizer application and the pest control is performed by the switching operation of the claw clutch 33 shown in FIG.

That is, in the case of the control work, since it is necessary to continuously spray the chemical liquid from the large number of spray nozzles 16, the pump shaft 27 is used for the purpose of increasing the discharge amount of the pump 27 and increasing the discharge pressure. The rotation transmission part 35a that constantly rotates the 'maximizes the operating stroke of the pump 27, while in the case of fertilization work, the number of nozzles is small (two) and fertilizer is applied to the soil at regular intervals. Since it is necessary to reduce the discharge rate of fertilizer as compared with the case of the above-mentioned control work because it is dusty with point fertilizer application, during the point fertilizer fertilizer transmission mechanism, rocking occurs within the range of reciprocation below the total stroke It is driven by a crank transmission portion 35b, and these switching is performed by a switching mechanism 35c having the pawl clutch 33. In addition, the crank transmission portion 35b is provided with a discharge amount adjusting mechanism D for adjusting the discharge amount of the pump 27 in accordance with the amount of fertilizer applied for point injection.

In FIG. 5, reference numeral R is a return circuit composed of a flexible transparent pipe (pipe line) 53 a having a cleaning nozzle 53, and a valve 57 where the pipe lines of the fertilizer application section F and the control section S join. 57a is connected to the downstream side of 57a, and the washing nozzle 53 is provided at the end of the 57a so as to return overflow to the tank 20 during fertilization work and pest control work. Further, as shown in FIG. 7, the bottoms of the pair of tanks 20 and 20 are communicated with each other by a pipe line 29a, and a drain having a stopper or a suitable lid is provided upstream of the valve 28 where the auxiliary tanks 22 and 22 join. The (drain pipe) 59 is provided in a branched manner. Then, the drain 59 provided in the pipeline 29a between the tank 20 and the valve 28 is positioned so as to be at the same height as or lower than the suction port 27a of the pump 27, and the drain 59 is properly discharged. The residual liquid in 29a is made as small as possible. Further, 56 and 56a are strainers of the control section, and 58 is a breather port.

Next, the transmission mechanism M shown in FIG. 4 will be described. The power from the engine E is transmitted to the forward drive shaft 42 and the reverse drive shaft 43 of the transmission 3a by the forward drive belt tension clutch 40 and the reverse drive belt tension clutch 41, respectively. By the switching operation of 41, it moves forward or backward. At this time, since the reverse shaft 43 also serves as the PTO shaft, power is transmitted from the reverse shaft (PTO shaft) 43 to the first shaft 44, and in the case of fertilizing work, the point-feeding clutch 45 is further added. To the second shaft 46 and then to the third shaft 48 by the pin clutch 47, and the chain 49 rotationally drives the fourth shaft 34 and the valve shaft 31 'of the intermittent valve 31, 31a.

The rotation of the fourth shaft 34 causes the crank rod 36 to reciprocate, and the fifth shaft 35 to rotate via the claw clutch 33, so that the pump drive chain 50 reciprocates to operate the pump 27. It is designed to let you. A switching device Q for injecting pitch (for example, 20 cm and 30 cm) is provided between the second shaft 46 and the third shaft 48, and the injecting pitch can be switched to a plurality of stages by switching operation of the pin clutch 47. I am configuring. Further, in the case of the control work, the desired chemical solution is stored in the tank 20, the valves 55 and 55a are closed, the valves 57 and 57a are opened, and the point injection clutch 45 is disengaged. Insert the clutch 41 and move the aircraft 1 backward.

The fertilization work or the control work carried out by the fertilizer application machine according to the embodiment described in detail above is carried out after selecting a liquid fertilizer or a liquid such as a chemical solution suitable for the above work and supplying it to the tank. In the case of supplying, for example, a paste-like liquid fertilizer in this supplying operation, as shown in FIG. 8, the lid 20a is removed and the paste is supplied from the supply port 20b of the tank 20 on the filter 20c side having the mesh M having a large mesh. When the liquid fertilizer is supplied from the fertilizer container W, the liquid fertilizer is quickly filtered from the mesh M and supplied to the one tank 20, but the tank 20 communicates with the other tank 20 through the pipeline 29a. As the liquid fertilizer is supplied to one of the tanks 20, the liquid fertilizer is also supplied to the other tank 20 through the pipeline 29a, so that both tanks 20 and 20 are uniformly and well filled. Become.

When a chemical solution such as a disinfectant is supplied to the tanks 20 and 20, after the cleaning of both tanks 20 and 20 and each flow path is completed, a filter 20d having a mesh m with a small mesh is provided. A stock solution such as a disinfectant is put into the supply port 20b of the tank 20 on the side of, and a necessary amount of diluted dissolved water is supplied. When the diluted dissolved water is water for rivers in the field, various foreign substances such as dead leaves and debris are mixed in the water, and these foreign substances are used in the filter 20d having the above-mentioned small mesh. Thus, the spray nozzle 16 and the like can be accurately selected and removed, and the spray nozzle 16 or the like does not have a problem such as clogging, and the filtration can be quickly performed to perform a good supply operation. Then, similar to the above, the other tank 20 is uniformly filled with the chemical liquid through the conduit 29a.

When the granular fertilizer is diluted with water, the granular fertilizer is put into the filter 20c side and the water is put into the filter 20d side at the same time so that the feeding work can be performed quickly and accurately, which is convenient. Is. It should be noted that a switching valve and a pipeline may be installed side by side so that the tanks 20 and 20 individually communicate with the pump 27 in the pipeline 29a where the tanks 20 and 20 merge. It is possible to store different kinds of liquids in each of them and conveniently perform the corresponding management work.
