Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an improvement of a conveyor belt forming a conveyance path of a legume harvester that harvests legumes such as soybeans.

(Prior Art) A legume harvester for harvesting legumes such as soybeans, for example, as shown in FIG. By connecting it to an accumulation processing section provided in There is a system in which the fuel is transported, and when a predetermined amount has accumulated in this accumulation processing section, it is manually or automatically released onto the ground.

Here, conventionally, for example, as shown in Fig. 5,
By providing protrusions 5 made of sponge or the like on the surfaces of a pair of belt bodies 4 stretched across each other to form a conveyance path, it is possible to sandwich and convey the legume stalks between these protrusions 5. I was doing it.
Reference numeral 6 denotes a V-belt provided on the back surface of each belt main body 4, and this V-belt 6 is stretched around a pulley (not shown).

However, in the conveyor belt according to the above-mentioned prior art, since the gripping force of the protrusions 5 is strong, even a slight vibration causes the beans attached to the pods to fall off, thereby reducing the yield. A common way to prevent grain shedding during reaping is to perform the reaping work when there is still dew, such as early in the morning, but the problem with conventional techniques is that the reaping work is restricted. There is.

(Problem to be solved by the invention) The problem to be solved by the invention is to reliably prevent the shedding of legumes during reaping work, and to improve handling by making the conveyor belts used in pairs have the same structure. and to provide a conveyor belt that is highly economical.

(Means for solving the problem) The means for solving the problem in this invention are as follows:
A reaping section provided at the front end of a traveling machine body and a processing section provided at a predetermined position of the traveling machine body are connected via a conveyance passage, so that the beans harvested by the reaping section are transported to the processing section. In a reaper, an endless conveyor belt made of an elastic material, a side edge along the longitudinal direction of the conveyor belt on one side, and a two-way belt between the opposite side edge and the center line are used. A plurality of rod-shaped protrusions are provided in a row at regular intervals, and a protrusion is provided on the other surface of the conveyor belt along the longitudinal direction of the conveyor belt, and the conveyor belt is used in pairs and each of the conveyors The belts are mounted on a pulse harvester so that they face each other at a 180° phase, and each row of rod-shaped projections is inserted into the row of the other rod-shaped projections, and the beans harvested by the conveyor belt are removed. It is characterized by forming a conveyance path.

(Function) The conveyor belts 10 are used in pairs, and the rows of bar-shaped protrusions 12 provided on the side edges of each belt face each other so that they are arranged above and below each other, and each row of bar-shaped protrusions 12 is connected to the other bar-shaped protrusion. It is inserted between the rows and held in tension to form a conveyance path.

(Embodiment) FIG. 1 is a perspective view of a conveyor belt according to the present invention, FIG. 2 is a sectional view, and FIG. 3 is a sectional view showing another embodiment of the present invention.

In these figures, the conveyance path is constituted by a pair of conveyor belts 10, and each conveyor belt 10
The belt main body 11 is formed into an endless belt, and a surface material 13 having a plurality of rod-shaped protrusions 12 is attached to the surface on the conveyance path side.

The rod-shaped protrusions 12 are provided in two rows at predetermined intervals on the surface of the surface material 13, one of which is continuously provided at regular intervals along the side edge of the surface material 13, and the other is provided in a row along the side edge of the surface material 13. They are continuously provided at regular intervals at intermediate positions between the center line and the other side edge along the longitudinal direction of the surface material 13. Note that the belt main body 11,
The rod-like protrusions 12 and the surface material 13 are made of highly elastic synthetic rubber to provide elasticity and durability. Reference numeral 14 denotes a protrusion that is integrally formed at the center of the back surface of the belt main body 11, and the protrusion 1
4 acts as a V-belt and is stretched over the V-groove of the pulley 15.

Further, as shown in FIG. 2, the pair of conveyor belts 10 configured as described above face each other so that the rows of rod-shaped protrusions 12 provided on the side edges of each conveyor belt 10 are arranged above and below each other, Each rod-shaped projection 12 is inserted between the rows of the other rod-shaped projections 12 and held in tension to form a conveyance path.

Therefore, when the conveyor belt 10 is rotated in a predetermined direction, the bar-like protrusions 12 engage from both sides between the stems of legumes that have been cut by the reaping section and sent into the conveyance path, moving the stems back and forth. Since the rod-shaped projection 12 is brought into contact with the rod-like projection 12 from the opposite direction, cut beans and the like can be conveyed in the length direction of the conveyance path.

For this reason, unlike in the past, the stems are not strongly pinched from both sides, and vibrations during transportation are also less likely to be transmitted.

In the embodiment, one protrusion 14 is provided at the center of the back surface of the belt body 11, but if the amount of conveyance is large, for example, as in another embodiment shown in FIG. Two protrusions 14a, 1
4b is provided so that the driving force of the belt body 11 can be strengthened.

Further, in each of the embodiments, the surface material 13 on which the rod-shaped protrusions 12 are formed is attached to the surface of the belt body 11, but the rod-shaped protrusions 12 may be integrally implanted on the surface of the belt body 11. I can do it.

(Effect of the invention) The present invention has two parts on the surface of the conveyor belt that form the conveyor path, between the side edge, the opposite side edge, and the center line.
When forming a conveyance path by forming a plurality of rod-like protrusions at regular intervals in a row, each row of rod-like protrusions is inserted into the other row of rod-like protrusions, so the conveyor belt has the same structure. Since it is only necessary to prepare the material, it is possible not only to prevent grains from falling off during the reaping operation, but also to have the effect of being easy to handle and economical.
