Description

[Detailed Description of the Invention] Industrial field of application The present invention relates to an improvement of a fertilizer application device mounted on a paddy working machine such as a rice transplanter or a submerged direct sowing machine.

Conventional technology and problems Conventionally, in rice transplanters, side row fertilizer rice transplanters that apply paste-like liquid fertilizer to the side row shallow layer part of the field in parallel with planting seedlings are already known and It is used.
In addition, a rice transplanter was applied to simultaneously apply liquid fertilizer to the upper and lower layers of the shallow and deep fields in the field in order to obtain the fertilizing effect of initial growth such as improved survival and the fertilizing effect of mid-term growth. Dan fertilizer transplanters) have also been proposed. However, in conventional side-row fertilizer applicators, fertilizer pumps, suction and discharge hoses,
In many cases, fertilizer application parts such as indicators are arranged using the space on one side of the machine, and if this side strip fertilizer application and deep fertilizer application are provided on the same side, the left-right balance of the machine will be poor and space constraints will occur. Also increases. In particular, a shallow fertilizer applicator and a deep fertilizer applicator are provided separately and fertilizers with different components (fast-acting fertilizer and slow-acting fertilizer, etc.) are applied to the top and bottom of the field, as well as soil and crops. This tendency becomes even stronger in the case where the fertilizer application gearbox is added to the fertilizer application device so that the amount of fertilizer application can be adjusted according to the type of product because the weight of the entire fertilizer application device increases.

Means for Solving the Problems Therefore, the present invention is a paddy working machine in which fertilizer is applied simultaneously to planting or sowing seedlings at the side row shallow layer position in the field and at the deep layer position every other row. In the left and right sides of the machine frame, a fertilizer pump for side strips and a pump transmission device for adjusting the side strip fertilizer application amount are provided on the left and right sides, and a pump transmission device for deep layer fertilizing and a pump transmission device for adjusting the deep fertilizer application amount are provided on the left and right sides respectively. It is intended to eliminate the above-mentioned problems by arranging them separately and arranging the operating portions of the respective pump transmissions near the driver's seat.

ActionSince the fertilizer pumps for shallow side and deep layers and the pump transmissions for adjusting the fertilizer application amount are distributed to the left and right sides of the machine frame, piping to fertilizer tanks and indicators is easy and the machine is The left-right balance of the aircraft becomes good and the aircraft travels stably. Further, since the operating portion of each pump transmission is arranged near the driver's seat, the fertilizer application amount can be adjusted at the driver's seat position, and the operability is further improved.

Example A riding rice transplanter is shown in the drawings, which includes a traveling part A, a part of which is omitted, and a four-row planting part B, which is mounted rearwardly of the traveling part A via an elevating link M so as to be vertically movable. ing. On the left and right sides of the front part of the running part A, there are fertilizer tanks 1 and 1'for side strips containing paste-like fertilizers at relatively low positions, and in the center of the front part of the running part A, fertilizers for deep layers. The tanks 2 are mounted on the machine body frame 3 via stays 4 in good balance. Reference numeral 4a denotes a guard of the deep-layer fertilizer tank 2, which is attached to the stay 4 so as to surround the front surface and both side surfaces of the tank 2.

Although the drawing shows an example in which three fertilizer tanks are provided, one for the lateral strip and one for the deep layer may be provided side by side.

By the way, a fertilizer pump 6 for side strips and a pump transmission device for adjusting the side strip fertilizer application amount (transmission device for side strips) are located below the driver's seat 5 on one of the left and right sides (left side in the drawing) of the machine body frame 3.
On the other side, a fertilizer pump 8 for deep layer and a pump transmission device (transmission device for lateral strip) 9 for adjusting the amount of deep fertilizer application are arranged in a set so as to be distributed right and left in a balanced manner. Reference numeral 10 denotes an operating portion of the lateral line transmission 7, and 11 denotes an operating portion of the deep layer transmission 9. The main transmission levers 10a, 11b and the sub-transmission levers 10b, 1 respectively.
1b, etc., and these operation units 10 and 11 are arranged in a space near the driver's seat 5 in a horizontally distributed manner in a plan view so that they can be operated by one touch from the driver's seat 5. ing. The fertilizer pumps 6 and 8 are connected to the fertilizer tanks 1 1 ′ and 2 on the suction side via suction pipes 12 and 13, respectively, and on the discharge side to the fertilizer nozzles described later via discharge pipes 14 and 15, respectively. In the middle of the piping of the discharge pipes 14 and 15, indicators 16 and 17 for confirming the flow of fertilizer are respectively arranged at the rear of the fertilizer application pumps 6 and 8 symmetrically with respect to the center of the machine. 18 is a side-row fertilizer nozzle for applying fertilizer to the side-row shallow layer position in the field adjacent to the planting row, and is provided for each row. Reference numeral 19 is a deep-layer fertilizing nozzle for fertilizing at a deep-layer position, which is provided for each rib. In this way, the deep-layer fertilizer tank 1, 1 ′, the fertilizer pump 6, the pump shift position 7, the indicator 16 and the deep-layer fertilizer device b including these pipes are provided separately from the side-row fertilizer device a. ,
Fertilizers with different components can be applied to the shallow and deep layers of the field, and the amount of each fertilizer can be adjusted separately.

In the illustrated example, the side strip fertilizer nozzle 18 is provided with a central float 20.
1 in the vicinity of the left and right side edges of the side float 21 and 1 in the vicinity of the outer edge of the side float 21, a total of 4 deep fertilizer nozzles 19 are positioned below the front part of the side float 21 to attach the planting part mounting bracket. It is one in which two ribs are provided on 22 via a torsion bar 23.

By supporting the deep fertilization nozzle 19 via the torsion bar 23, the resistance of the tiller and the obstacle against the nozzle 19 is received not by the float 21 but by the machine side, and the rolling of the planting part B or the float 21 It is possible to prevent the planting posture from being disturbed and the nozzle 19 from being deformed due to tilting, rising, and the like. Reference numeral 24 is a square pipe, 25 and 26 are nozzle support portions, 27 is a rowing fulcrum of the planting portion B, 28 and 29 are rotational fulcrums, 30 is a mounting bolt, and 31 is an elongated hole for adjusting the fertilization depth.

7 and 8 show a deep-layer fertilizing nozzle 19 supported by a square pipe 24a fixed to a lower link 32 of a planting section elevating link M with a fitting 33 so as to be vertically rotatable, The other structure is substantially the same as that of the embodiment shown in FIG. As a result, even if the deep fertilizer nozzle 19 receives soil resistance, rolling of the planting part B does not occur, the planting posture is not disturbed, and the lower link 32 approaches the planting part mounting bracket when traveling. Since the nozzle 19 is tilted, the amount of protrusion to the lower part of the float is reduced, so that the nozzle tip can be prevented from being deformed by hitting an obstacle such as a ridge (especially easily deformed in the lateral direction).

What is shown in FIGS. 9 to 11 is a planting part mounting bracket 22.
A nozzle mounting frame 34 is fixed to the frame 34, a deep fertilizing nozzle 19 is pivotally supported on the frame 34 in a vertically rotatable manner, and an arm 35 fixed to the nozzle 19 and a lower link 32 are connected by a rod 36. Insert the round bar 38 into the round pipe 37 so that it can slide up and down, and insert the round bar 38 into the stopper position 40 via the ammunition 39.
Abutted against. 41 and 42 are pivot pins, and 43 is a fertilization depth adjusting hole. In this configuration, when an excessive push-up load is applied to the tip of the nozzle 19, the ammunition 39 is pulled and the nozzle 19 rotates upward to reduce the load, and at the time of traveling, the nozzle 19 is similar to the previous example. Rotate upward to prevent deformation of the nozzle due to obstacles.

The fertilizer application position (depth) is set to 3 to 5 cm from the rice field for the lateral strip fertilizer nozzle 18 and 8 to 15 cm for the deep fertilizer nozzle 19, but by changing the inclination angle of each nozzle 18,19. The height of fertilizer application can be adjusted appropriately. Further, since the fertilizer application pumps 6, 8 and the indicators 16, 17 are arranged separately for the lateral strips and for the deep layer, the piping between the pumps 6, 8 and the fertilizer application nozzles 18, 19 is connected to the top link 32a or the lower link 32. It can be performed without straddling, and not only the assembling of the fertilizer application becomes easy, but also the disadvantages such as the piping being pulled by the top and bottom of the planting part B and being damaged can be eliminated.

Although not shown in the figure, the central float 20 has a function of detecting the upper and lower parts of the planting part B, and detects the change in the ground pressure of the central float 20 to control a hydraulic valve (not shown). The attachment part B is vertically adjusted to keep the planting depth constant.

3 to 5 show fertilizer pumps 6 and 8 and their transmissions 7 and 8.
In the explanatory diagram of the power transmission system, the transmissions 7 and 9 are fertilizer pumps 6 and 8.
It is installed during the transmission of, and the power of the fertilizer pumps 6 and 8 is PTO.
It is designed to be introduced from the axis 44. That is, fertilizer pump
The transmission to 6, 8 is from the PTO shaft 44 to the input shaft of the side-strip transmission 7.
After being chain-transmitted to 45, the power is transmitted from the output shaft 46 of the side-line transmission 7 to the pump shaft 47 of the side-line fertilization pump 6 (four pieces) by chain transmission, and the other from the input shaft 45. The chain transmission enters the input shaft 48 of the deep-layer transmission 9, and the output shaft 49 of the chain further transmits the chain to the deep-layer fertilizing pump 8 (2).
The power is transmitted to each pump shaft 50. The rotation speeds of the fertilizer pumps 6 and 8 are adjusted by operating the main shift levers 10a and 11a and the sub shift levers 10b and 11b, respectively. Incidentally, in order to make the fertilizer application amounts on the side row side and the deep side side the same, in the embodiment, since there are two side row side pumps and two deep side side pumps, the rotation of the deep side side pump 8 is performed. It suffices to set the number to the double speed of the rotation speed of the side strip side pump 6, and in that case, if the positions of the side strip side and the deep layer side shift levers are the same, the fertilizer application amount becomes the same amount, and the fertilizer application amount management becomes easy. It can be carried out.

The present invention can be installed not only on a paddy rice transplanter, but also on a paddy working machine such as a walk-behind rice transplanter or a direct seeder for flooded soil.

In the above configuration, when performing planting (fertilization) work, paste fertilizer suitable for initial growth of crops is previously stored in the lateral strip fertilizer tanks 1 and 1 ', and the delayed-release fertilizer supplementation is applied to the deep-layer fertilizer tank 2. Paste-like fertilizers are put in each, and the fertilizer application positions of the nozzles 18 and 19 are set to appropriate depths according to field conditions, varieties and the like. Then, when the planting clutch is turned on and the machine is advanced, seedlings are planted in the planting section B, and fertilizers for side strips and deep-layer fertilizers are respectively fed from the fertilizer tanks 1, 1 ′ and 2 to the suction hoses 12. , 13, fertilizer pumps 6,8, discharge hoses 14,15, indicators 16,17 are separately sent to the rear of the machine, then fertilizer for side strips is applied to each planted strip by fertilizer nozzle 18. The fertilizer for deep layer is applied to the adjacent shallow positions of the lateral strips by the fertilizing nozzle 19 at the deep position between the planting strips. As a result, the lateral row shallow layer fertilization as the base fertilizer and the deep layer fertilization as the top fertilizer are performed at a proper ratio and density in relation to the planting strip, and the survival and growth in the early stage of growth are improved and the fertilizer as the top fertilizer in the middle growth stage is applied. The effect is further enhanced. The fertilizer application rate is 6,
Although determined by the number of rotations of 8, the speed change levers 10a, 10b, 11a, 11b of the pump speed change devices 7, 9 are operated as needed to increase or decrease the fertilizer application amount.

Effect of the Invention As described above, the present invention is a paddy working machine in which fertilization is applied simultaneously to planting or sowing seedlings at each row at the lateral row shallow layer position and at the deep layer position every other row. The fertilizer pump for side strips and the pump speed changer for adjusting the side strip fertilizer flow rate are distributed to the left and right sides of the machine frame, and the fertilizer pump for deep sea level and the pump speed changer for deep layer fertilizer flow rate are respectively distributed to the left and right sides. In addition to being installed, the operation part of each pump transmission is installed near the driver's seat, so piping to each fertilizer tank etc. can be easily performed, and the left and right balance is good and the aircraft running is stable. Can be realized. In addition, the amount of fertilizer applied can be controlled at the driver's seat position, further improving the operability.
