Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a vacuum car capable of sucking, loading, transferring, and discharging manure, sludge, waste liquid, and the like, especially in remote areas of mountains. Small-sized vacuum car that can drive even narrow roads.

[Prior Art] Conventionally, various vacuum cars have been developed, and large vacuum cars or small vacuum cars have been put into practical use according to their respective scales.

By the way, the conventional vacuum car as described above is a dedicated car and is generally expensive, and even a small car cannot drive on a narrow road in a remote mountain area, and these remote islands and remote areas are processed by old manpower. It is the actual situation. However, since this manual processing is mainly a fertilizer burden, it involves heavy labor, and is becoming a social problem due to recent labor circumstances, especially due to changes in the labor force in remote areas of Yamamura.

Therefore, it is possible to apply the vacuum car currently developed and put to practical use to remote areas of mountain villages, but as mentioned above, the width of the road is narrow in the mountainous areas, and steep slopes, steep slopes or unpaved roads are used. Therefore, it is not possible to drive safely, and in addition, houses in mountain villages and remote areas are generally sparsely distributed and the number of houses is small, so there is also a problem that expensive vacuum cars do not make money.

Generally, a small vacuum car is known, and the actual size is 43-
It is disclosed in Japanese Patent No. 11238. However, in such a known technique, since the model is towed by a tractor, horsepower is insufficient due to a steep slope in a mountain village, or driving on a curved road is not safe.

Japanese Utility Model Publication No. 36-24006 discloses a vehicle equipped with a manure tank. However, this known technique is not efficient because the supply and discharge work is performed with a single hose as in the above-described known example.

Further, Japanese Patent Publication No. 36-2512 discloses an automatic adjusting device for each device according to a pressure change in the tank of a vacuum car, but it is not suitable for remote areas of Yamamura.

[Problems to be solved] Therefore, the object of the present invention is to reduce the number of houses to be fetched such as in remote areas of remote areas such as mountain villages, remote islands, etc. In addition, the road can be driven on narrow and steep roads with many sharp curves, and operation and supply / discharge work is easy. To provide a small vacuum car.

[Means for Solving the Problems] According to the small-sized vacuum car of the present invention, the front and rear wheels are both 1.2 m or less in width, the tire size is 500 mm or less, and the four-wheel drive type is capable of both front riding and walking pulling. Vehicle, a relatively small tank having a barrel diameter of 0.5 to 1.2 m, which is attached to the rear part of the frame of the vehicle by bolts and nuts, and an auxiliary device arranged in the front position from the center of the vehicle. A suction pipe and a discharge pipe each having a suction valve and a discharge valve are provided at the rear part of the tank, and the upper part of the tank is opened at the lower position and closed at the upper position where the liquid is full. A float valve is provided, and the accessory device is provided in a vacuum pump driven by a drive engine of the automobile and a piping system connecting the vacuum pump and the tank, and is operated by a switching operation. And suction and discharge switching valve and vacuum the tank, also pressurizing, provided in the piping system and a separator for separating the mist from the air.

[Advantageous effects of the invention] Since the present invention is configured as described above, a four-wheeled vehicle is now driven to go to the house where it should be collected. Then, the vacuum pump is started using the engine of the automobile. Operate the intake / exhaust switching valve to reduce the pressure inside the tank. Insert the hose connected to the suction tank into the filth tank while reducing the pressure. Then, it is sucked into the sludge liquid tank. The mist in the intake air during operation is separated by the separator and does not reach the vacuum pump.

When the suction work is completed, move to the next house to be pumped and carry out the same pumping work. When the tank is full, the float valve closes, so that you can know the full volume.

When the vehicle is full, drive the car and discharge to the appropriate tank. For example, when it is applied to a remote island, it is discharged to a storage ship by the operation described later. Reservoirs store several doses of manure and are towed to the harbor of the large island where the treatment plant is located. The island will be transshipped to a conventional large vacuum car and transported to the treatment plant. In the remote areas of Yamamura, the manure collected around each house is temporarily stored in a storage tank and then transported to a treatment plant by a large vacuum car. Also, in places where there are few flatlands and densely packed houses such as fishing villages, it is difficult to obtain the land for constructing storage tanks.Therefore, the vacuum car of the present invention is transferred directly to a large vacuum car, and then a large vacuum car is sent to the treatment plant. Can be carried.

To drain the waste liquid from the tank of the present invention, a vacuum pump is driven by the engine of a four-wheeled vehicle. Then, the intake / exhaust switching valve is operated to pressurize the inside of the tank. Insert the drain pipe into the reservoir and open the drain valve. Then, the manure in the tank is effectively discharged to the storage tank by the pressure. Natural discharge is also possible if the storage tank is installed at a lower position.

As described above, according to the present invention, since it is a four-wheeled vehicle that has been diverted from an agricultural transport vehicle, the width of both the front and rear wheels is relatively narrow, for example, 1.2 m or less. Also, you can drive to every corner. Especially in narrow alleys, you can drive before walking, so you can drive while checking safety. Moreover, since it is a four-wheeled vehicle, it can drive more stably than a three-wheeled vehicle or a tailor, and is safe on roads with steep slopes and sharp curves.

According to the present invention, the tank is also bolted to a four-wheeled vehicle.
Since it is attached by a nut, it can be removed as needed and used as a carrier. Since the float valve is provided in the upper part of the tank, it is safe because the manure does not reach the vacuum pump due to excessive suction.
Further, since the accessory device is composed of a small number of devices such as a vacuum pump, an intake / exhaust switching valve, a separator and the like, there is also an advantage that the entire vacuum car is inexpensive. Also, the tank has a relatively small body diameter of about 0.5 to 1.2 m, but there is no problem because the number of units is small.

Further, in the present invention, since it is a four-wheel drive vehicle, it is possible to drive on soft ground or unpaved rough terrain without trouble.
Also, since the tires use small wheels with a diameter of 500 mm or less, a relatively small engine can run on a steep slope, and the vehicle height becomes low and stable.

Further, according to the present invention, the driver can perform a front-walking pulling operation in which the driver pushes the car from the front to move the vehicle forward by tilting it forward as is done with an agricultural machine.

[Embodiment] An embodiment of the present invention will be described below with reference to the accompanying drawings.

Now, referring to FIG. 1, FIG. 2 and FIG. 3, the small vacuum car C according to this embodiment is a four-wheeled vehicle 30.
