Description

The present invention relates to an agricultural transportation device capable of reducing labor in transporting harvested agricultural products, fertilizers, compost and the like.

When harvesting crops in fields such as fields and orchards, farmers can, for example, harvest the crops and store them in containers, transport the containers to trucks, load the containers onto truck beds, and from there. We are doing various labor-intensive work such as moving to another place and loading and unloading the container. Agricultural machinery is used to reduce this effort, for example, a harvester with a conveyor that automatically harvests and stores the harvest in a container, or when the harvest location is far from the truck. It is known that trucks such as unicycles and four-wheeled vehicles, or powered trucks, etc., are used in the field.

However, in the transportation work, fertilizers and compost are often transported to the field in addition to the harvested products, and although it takes a lot of labor to load and unload those trucks on the loading platform, it is difficult to mechanize and it is necessary to rely on human power. I don't get it.
Moreover, in recent years, the population of agricultural workers has decreased, and in an environment where the population is aging, it takes time to transport with a small number of people, and the amount that can be transported by one person is limited, so the labor of agricultural work Is further desired to be reduced.

On the other hand, the transportation route is often uneven due to uneven surfaces such as soil, and there is a risk of damaging the harvested product due to vibration or impact during transportation by the trolley.

On the other hand, Patent Document 1 discloses a conveyor capable of absorbing an impact by using an air mattress. The conveyor of Patent Document 1 can transport fruits and vegetables while moving them in a rolling manner by mechanically moving the air mattress in a wavy manner.

Jitsukaisho 63-113010 Gazette

However, the conveyor of Patent Document 1 requires a mechanical driving means for moving the air mattress in a wavy manner. The drive means moves the elevating arm up and down and repeatedly deforms the transport surface alternately into valleys and peaks to make the transport surface wavy, but it is a large-scale mechanical drive device. The installation cost was high and heavy. Therefore, once the installation location is fixed, it is difficult to move the conveyor to another location, and the conveyor is not compatible with installation at the harvest location.

[Embodiment 1]
As shown in FIG. 1, the agricultural transport device 1 of the present invention includes an air air supply / exhaust means 2 and a transport unit 3. The transport body 3 has a transport body 3a, a fixing portion 3b, and an air supply path 3c, and the transport body 3a is a hollow body having a plurality of partitioned air chambers made of a soft material. It can be deformed into a wavy shape by supplying and exhausting air to the air chamber by the air supply / exhaust means 2.

The transport main body portion 3a of the transport unit 3 is a portion on which a transport object such as a harvested product, a container, fertilizer, or compost is placed. The transport main body 3a is a hollow body made of a soft material, and since the hollow portion is filled with air during use, it is possible to absorb vibrations and shocks during transport, resulting in damage to the object to be transported. Can prevent scratches.

As the soft material constituting the transport main body 3a, a film or sheet made of a thermoplastic resin can be used. Examples of the thermoplastic resin include a polyvinyl chloride resin, a thermoplastic polyurethane resin (TPU), a polyofine-based resin, and a copolymer polymerized using two or more kinds of monomers. In particular, TPU is preferable in terms of ease of wavy deformation and foldability, which will be described later.

The soft material referred to in the present invention may be any material as long as it can be folded and deformed in a wavy shape as described later. For example, a thickness of 0.1 mm or more and 2 mm or less and a value measured by an A-type hardness tester in accordance with JIS K 7311 of 50 to 100 can be used.

Depending on the object to be transported and the usage conditions, a functional layer such as wear resistance, stain resistance, and water resistance may be imparted to the surface of the transport main body portion 3a of the present invention.

In the first embodiment, the transport main body 3a uses a hollow body having a plurality of partitioned air chambers, and by controlling the air supply / exhaust to each air chamber, the transport main body 3a is deformed in a wavy shape. Can be done. In the present invention, the number and position of air chambers are not particularly limited as long as they are hollow bodies having a plurality of partitioned air chambers made of a soft material that can deform the transport main body 3a in a wavy shape by air supply / exhaust.

As will be described later, when the air is deformed into a wavy shape by air supply / exhaust, the internal pressure of the transport main body 3a when air is supplied may be 0.05 Pa or more. Further, although it depends on the material constituting the transport main body 3a, the upper limit is adjusted in the pressure range of about 0.8 Pa.

The fixing portion 3b of the transporting portion 3 of the present invention is a portion in which the transporting main body portion 3a and / or the air supply path 3c is fixed at the installation location. I am using something.
In the present invention, the object placed on the object is transported by deforming the transport main body 3a in a wavy shape, but the transport main body 3a itself is fixed in order to prevent the transport main body 3a itself from moving due to the wavy deformation. A part 3b is provided.

The position of the fixed portion 3b may be a position that does not hinder the operation of the transport main body portion 3a. In the first embodiment, the fin-shaped fixing portions 3b are provided at both ends with respect to the moving direction of the transport main body portion 3a, but they may be provided on the side surface of the transport main body portion 3a or the air supply path 3c described later. Further, fixing portions 3b may be provided at the four corners of the transport main body portion 3a, and if the positions are the same, the transport main body portion 3a can be fixed without being hindered.
The fixing portion 3b may be detachably provided from the transport main body portion 3a and / or the air supply path 3c, or may be joined and integrated with the transport main body portion 3a and / or the air supply path 3c.

The shape of the fixing portion 3b is not particularly limited, and may be a bag shape other than a fin shape.
For example, when the fin-shaped fixing portion 3b is used, the fixing portion 3b may be fixed by hitting a pin, or if the pin cannot be hit, a weight such as soil is placed on the fixing portion 3b to fix the fixing portion 3b. You can also do it.
When the bag-shaped fixing portion 3b is used, the inside of the bag-shape can be filled with water or soil and fixed as a weight.

The fixing portion 3b is preferably formed of a soft material like the transport main body portion 3a. This is because, as will be described later, it can be folded at the same time as the transport main body portion 3a. As the soft material, the thermoplastic resin mentioned in the transport main body 3a may be used.

In addition, in the present invention, it can be fixed to a truck bed or a high place (between trees) in addition to the ground, and the fixing means at that time is also a fixing portion 3b. For example, strings, wires, rings, hooks, carabiners, magnets, etc. can be used.

In the first embodiment, the air supply path 3c of the transport section 3 of the present invention has a soft tube inserted as an air supply path 3c into each of a plurality of air chambers constituting the transport body section 3a, as shown in FIG. .. The air supply is not particularly limited as long as it can be supplied, but as will be described later, it is preferable to use a soft tube so that it can be folded.
As the soft tube, a tubular or a soft film may be rolled into a tubular shape, and a tube having a circular cross-sectional shape or a substantially flat shape can be used.

The air supply / exhaust means 2 of the present invention is a means for deforming the transport main body 3a in a wavy shape by controlling the air supply / exhaust to the hollow body constituting the transport main body 3a. In the first embodiment, the air supply / exhaust means 2 composed of the air control device 2a and the air supply device 2b is used.

The air control device 2a of the present invention adjusts the amount and timing of supplying the air supplied from the air supply device to the transport main body 3a through the air supply path 3c, and exhausts the air from the transport main body 3a. It adjusts the timing.
Specifically, if air is sequentially supplied to the air chambers adjacent to the transport main body 3a, the transport main body 3a can be deformed into a wavy shape and the wavy shape can be propagated in the traveling direction.

For the air supply device 2b of the present invention, for example, a compressor can be used.

[Embodiment 2]
As shown in FIG. 2, the agricultural transport device 12 of the present invention includes an air air supply / exhaust means 2 and a transport unit 3. The transport unit 3 has a transport main body portion 3a, a fixing portion 3b, an air supply path 3c, a fall prevention guide 3d, and a shape maintaining portion 3e. The air supply / exhaust means 2, the transport main body portion 3a, the fixing portion 3b, and the air supply path 3c are the same as those in the first embodiment.

The fall prevention guide 3d of the present invention is provided so that an object does not fall from the transport main body 3a during use. For example, a plurality of substantially cylindrical air columns i as shown in FIG. 2 and the air. It is possible to use a wall-shaped air column in which a curtain body j is attached between the columns i, or a wall-shaped air column provided along the length direction of the transport main body portion 3a (not shown). By using a cylindrical or wall-shaped air column for the fall prevention guide 3d, it is easy to fold and install because it is only necessary to fill the air when in use and bleed the air when not in use, as in the case of the transport body 3a. preferable.

The fall prevention guide 3d is preferably made of a soft material so that it can be folded, as will be described later. Further, as the soft material, the thermoplastic resin mentioned in the transport main body 3a may be used.

The mounting position of the fall prevention guide 3d may be a position that does not interfere with the operation of the transport main body portion 3a. In the second embodiment, a substantially cylindrical air column i is joined to the fixed portion 3b, and the curtain body j is joined only to the air column i and not to the transport main body portion 3a, so that the transport main body portion 3a has a wavy shape. Does not prevent deformation.
The fall prevention guide 3d may be detachably provided from the transport main body portion 3a, the fixed portion 3b, or the air supply path 3c, or may be joined and integrated with the transport main body portion 3a or the fixed portion 3b.

The shape maintaining portion 3e of the present invention is provided to prevent the transport main body portion 3a from being twisted or bent during use, and for example, a plate-shaped air column k as shown in FIG. 2 is used. Can be done.
By using the plate-shaped air column k for the shape maintaining portion 3e, it is preferable to fill the air when in use and to bleed the air when not in use, as in the case of the transport main body portion 3a, because it is easy to fold and install.

The shape maintaining portion 3e is preferably made of a soft material so as to be foldable, as will be described later. As the soft material, the thermoplastic resin mentioned in the transport main body 3a may be used.
Further, if necessary, a non-slip may be provided at a position in contact with the installation surface.

The mounting position of the shape maintaining portion 3e may be a position that does not interfere with the operation of the transport main body portion 3a. In the second embodiment, the plate-shaped air column k is provided on the back side of the transport main body 3a, but it is fixed only to the fixed portion 3b so as to be flexible enough to follow the movement of the transport main body 3a. Since the pressure of the air to be filled is adjusted, it does not prevent the transport main body 3a from being deformed in a wavy shape.
The shape maintaining portion 3e may be detachably provided with the transport main body portion 3a, the fixing portion 3b, and the fall prevention guide 3d, and is joined to the transport main body portion 3a, the fixing portion 3b, the air supply path 3c, and the fall prevention guide 3d. And may be integrated.

The role of the shape maintaining portion 3e may be played by the fixing portion 3b or the fall prevention guide 3d.

The transport unit 3 of the agricultural transport devices 1 and 12 of the present invention can be folded because the transport main body portion 3a is made of a hollow body made of a soft material.
For example, when the size when filled with air is about 400 mm in width, 3 m in length, and 2.0 mm in thickness, the air is evacuated and folded into a cylindrical shape as shown in FIG. 3, so that the height is 400 mm and the diameter is 400 mm.
