ンクが試みられている。 Recently, some cylinders of engines installed in vehicles are used as air compressors by cutting off the fuel supply with fuel stop valves controlled by powder discharge switches, and the compressed air is used as exhaust valves. Attempts have been made to create a powder transport tank in which the powder in the tank can be fluidized and discharged by switching with a compressed air on-off valve.

れてしまうという事故を招く恐れがあつた。 However, the powder discharge switch is located on the cab side.
Since the fuel stop valve is installed on the engine side, the vibration systems of the husband and husband are different, so it is possible that a break may occur in the circuit connection between the two. In that case, the fuel stop valve is installed in the exhaust pipe of the cylinder. Since only the exhaust on-off valve and the compressed air on-off valve were activated, there was a risk that combustion gas would be introduced into the tank, leading to an accident in which the powder and granules in the tank would be damaged.

る。 This invention was devised to solve this problem.If the fuel stop valve does not operate due to a disconnection in the connection circuit, etc., the exhaust on-off valve and the compressed air on-off valve do not operate. The purpose of the system is to provide a control device for tank cars.The compressed air obtained by stopping fuel in some of the cylinders of the engine mounted on the vehicle is turned into powder and granular material by blocking the exhaust passage and opening the branch passage. A fuel stop solenoid valve configured to supply fuel to a transportation tank, and configured to include a compressed air opening/closing solenoid valve provided in the branch path, and an exhaust gas opening/closing solenoid valve provided in the exhaust path, for stopping fuel to the cylinder. The device is characterized in that it is configured to be activated by a contact that is connected only by the activation of the device.

ている。 The branch path 22 is connected to the bottom 26a of the powder transport tank 26 via an on-off valve 22a.
A powder discharge duct 27 extends outside the tank 26, and an on-off valve 28, which is opened and closed by appropriate means, is provided near the discharge port 28a.

となるから左バンク２の各シリーズ＃１，３，
５，７は圧縮機として作動する。 In the present embodiment configured as above, when discharging the granular material in the tank 26, when the discharging switch 19 is closed, the current first flows from the battery 18 to the solenoid valve 15 via the switch 19. Since the valve body 15b operates and closes its internal passage, oil supply from the oil passage 12 to the injection pump 10 is cut off. Therefore, since the injection pump 10 is in a non-injection state, each series #1, 3, and
5 and 7 operate as compressors.
前記弁体１５ｂの作動によつて、可動接片１５
ｆが接点１６ｇと１６ｈとを接続する。 Due to the operation of the valve body 15b, the movable contact piece 15

る。 As a result, the electromagnetic valve 9 is actuated and the air passage 8 is opened, so that compressed air from the air tank 7 flows through the air passage 8 to the operating mechanism of the exhaust opening/closing valve 6, thereby closing the valve 6. Since the electromagnetic valve 23 is energized at the same time as the electromagnetic valve 9 is energized, the opening operation thereof brings the exhaust path 4 and the branch path 22 into communication.
The compressed air from each cylinder C 1 , C 3 , C 7 of the left bank 2, which acts as a compressor that simply takes in air and pressurizes it, is not exhausted outward from the exhaust path 4 but is sent to the branch path 22 side. be done. If the on-off valve 22a is opened here, the water is introduced into the bottom 26a of the tank 26.
従つて、タンク２６内の粉粒体は、加圧空気に

とがない。 Here, the powder discharge switch 19 and the solenoid valve 1
If a disconnection or failure occurs in the circuit line 16a connecting 5 or in the solenoid valve 15, the solenoid valve 15 will not operate,
Since the movable contact piece 15f also does not operate, the contact 1 is connected only by the operation of this fuel stop solenoid valve 15.
The compressed air opening/closing solenoid valve 23, which opens and closes the supply of compressed air, and the exhaust opening/closing solenoid valve 9, which are connected to operate by 6g and 16h, are not driven.

きる。 In short, the control device for a tank car for transporting powder and granular materials according to the present invention uses compressed air obtained by stopping fuel in some of the cylinders of the engine mounted on the vehicle to block exhaust passages and open branch passages. to supply the powder to the granular material transport tank,
A contact that connects a compressed air opening/closing solenoid valve provided in the branch path and an exhaust opening/closing solenoid valve provided in the exhaust path only by activation of a fuel stop solenoid valve that stops fuel supply to the cylinder. Since it is configured to operate according to the following, the following effects can be achieved.

れも殆んど解消できる。 In other words, it does not include combustion components and fuel that are generated when the compressed air control solenoid valve that opens and closes the supply of compressed air and the exhaust opening/closing solenoid valve operate, and the solenoid valve that shuts off the fuel does not operate. It is possible to reliably prevent the exhaust gas from being introduced into the powder transport tank, and at the same time prevent the powder from being damaged by combustion gas. Moreover, since the exhaust opening/closing solenoid valve and the compressed air opening/closing solenoid valve are operated by contacts that are connected only by the operation of the fuel stop solenoid valve, there is almost no risk of wire breakage occurring as with conventional control devices. It can be resolved.
