Summary of the Invention

Problems to be Solved by the Invention

[0004] When using the above riding-type rice transplanter, it enters a field surrounded by ridges and exits from the field to the surrounding farm road after the transplanting work is completed. However, entering the field and exiting from the field require crossing the ridges around the field, and the traveling vehicle body becomes unstable when crossing the ridges. Therefore, in order to avoid the risk of tipping over, the operator has to get off the traveling vehicle body and operate in a forced posture while walking, and requires great care not to tip over the traveling vehicle body.

[0005] An object of the present invention is to provide a seedling transplanting system that allows an operator to perform a transplanting operation of transplanting seedlings into a field while staying in a safe place outside the field.

[Effects of the Invention]

[0011] In the invention of claim 1, the seedling tank 3 and seedling transplanting device 4 are suspended from a mobile trolley 1 stopped outside the field by a suspension link 2 and moved within the field, making it easy to move the seedling tank 3 and seedling transplanting device 4 over ridges, and allowing workers to safely perform seedling transplanting work in the field without having to enter the soft field.

[0012] In the invention of claim 2, the seedling tank 3 and seedling transplanting device 4, which are suspended by the suspension link 2, can be rotated horizontally to change the direction of transplanting, allowing for orderly transplanting across the entire field.

[0013] In the invention of claim 3, the field is tilled with the rotor 5, the traces are leveled with the float 6 to prepare the transplanting area, and seedlings are taken out of the seedling tank 3 with the seedling transplanting device 4 to perform the transplanting work, so that seedling transplanting can be performed at the same time as the land is prepared.

[0014] The invention of claim 4 allows fertilizer and chemicals to be scattered from the granular tank 7 onto the seedling transplanting area of ​​the seedling transplanting device 4, enabling fertilization and disinfection simultaneously with seedling transplanting, thereby reducing labor in post-transplanting work.

[Modes for carrying out the invention]

[0016] Hereinafter, embodiments of the present invention will be described with reference to the examples shown in the drawings.

[0017] Figure 1 is a side view of this seedling transplanting system, also called a field seedling transplanting device. A suspension link 2 is provided on a traveling bogie 1 installed on a raised path 11 provided around a field 10 and is suspended toward the inside of the field 10. A seedling tank 3 and a seedling transplanting device 4 inside the field 10 are pivotally suspended, and they are moved on the surface of the field 10 by the telescopic rotation of the suspension link 2. The seedling tank 3 places a seedling mat, and the seedling transplanting device 4 scrapes out each seedling plant from the seedling mat on the seedling tank 3 and plants it in the field 10 at regular intervals. The traveling bogie 1 is provided with a traveling device such as wheels or crawlers, moves on the raised path 11, stops at an arbitrary position, and is fixed at the stop position with an outrigger or the like.

[0018] The driving power for the left and right reciprocating movement of the seedling tank 3 and the transplanting operation of the seedling transplanting device 4 is provided by electric power through a power line wired along the suspension link 2 from the traveling bogie 1 or by hydraulic power through a piped hydraulic pipe.

[0019] Figure 2 shows the seedling tank 3 and the seedling transplanting device 4. Figure 3 additionally shows a rotor 5, a float 6, and a granular tank 7. The rotor 5 provided at the lower part of the seedling tank 3 tills the surface of the field 10, a float 6 for leveling the surface of the field 10 is provided at the front lower part of a pair of left and right seedling transplanting devices 4, and fertilizers and disinfectants can be sprayed from the granular tank 7 provided at the rear upper part of the seedling transplanting device 4 to the seedlings after transplantation. Note that the granular tank 7 may be provided at the front upper part of the rotor 5.

[0020] Figure 4 shows the telescopic and rotational range of the suspension link 2. The traveling bogie 1 is fixed at the edge of the field 10, and the seedling tank 3 and the seedling transplanting device 4 can be reciprocated three times to perform the seedling transplanting operation on the entire surface of the field 10.

[0021] Figure 5 is an explanatory diagram of a combine harvester's rice harvesting system. A drone 17 with a rice harvesting bag 18 suspended above it is flown close to the combine harvester 15. The drone receives the rice from the discharge port of the auger 16 that discharges the rice from the grain tank into the rice harvesting bag 18. Once the bag is full, the drone 17 is flown to a grain transport truck near the field to transport the rice. This eliminates the need for the combine harvester 15 to move around the field 10 to empty the grain tank even when it is full, allowing it to continue harvesting and increasing the efficiency of the harvesting operation.

[0022] Figure 6 shows an exhaust gas purification system for a diesel engine. DOC placed in the exhaust gas passage acts as an oxidation catalyst to generate NO2 from NO in the exhaust gas. This NO2 is used as an oxidizer to incinerate and remove particulate matter such as soot in the exhaust gas within the SCR muffler 20. The SCR muffler 20, including the connecting flange 22, is wrapped in an insulating material 21 to maintain a high temperature, while the NOx sensor 23 is placed outside the insulating material 21 to prevent it from overheating.

[0023] Figure 7 shows the temperature control of the exhaust gas inside the SCR muffler 20. The exhaust temperature is maintained at a high temperature by burning particulate matter. If particulate matter remains, the burning is performed at a lower temperature than usual for a longer period from the start of burning to prevent the generation of ammonia, and then the burning time is extended by controlling the temperature to a higher temperature than usual in the final stage, thereby enabling complete regeneration.

[0024] Finally, we will explain methods for reducing hydrocarbon emissions during rapid acceleration and deceleration of diesel engines, as well as during cold starts.

[0025] As the altitude of a diesel-engine-powered work machine increases, the air density also decreases, making it easier for misfires and the emission of unburned fuel to occur during rapid acceleration and deceleration at high altitudes. The same is more likely to happen during cold starts.

[0026] To address this issue, (1) atmospheric pressure and coolant temperature are measured, (2) an A / F sensor is installed on the engine, and (3) a map for fuel injection pressure and fuel injection quantity limits is installed on the control unit. Based on the A / F value from the A / F sensor, the EGR valve is adjusted to close as the altitude increases, and fuel injection quantity limits and injection pressure are regulated to ensure proper combustion. As the A / F value decreases, the fuel injection pressure is increased, and the turbocharger wastegate pressure is regulated to limit the output. Furthermore, an adjustment valve is installed in the exhaust section to direct exhaust gas around the DPF device.

[0027] This measure addresses the sudden lack of air by reducing the change in speed during acceleration and deceleration when atmospheric pressure is low, based on the relationship between the A / F ratio and coolant temperature. In addition, proper combustion is ensured by limiting the fuel injection amount and delaying the injection timing, preventing deterioration of exhaust emissions, and the fuel injection pressure is increased to facilitate ignition even in low air density. Furthermore, to prevent deterioration of exhaust emissions, power output is limited in high-altitude areas with low atmospheric pressure (areas with low air density), and exhaust pressure is increased by applying pressure with a pressure regulating valve in the exhaust section, which raises the exhaust temperature during aftertreatment and suppresses the emission of unburned fuel and white smoke.
