Description

[Detailed Description of the Invention] The present invention relates to a grain culm transporter that loads and transports grain culms etc. that have been harvested, tied up and released to a field.

Generally, the grain culms that have been harvested with a binder and then tied are released to the side of the machine by the release mechanism and are scattered over the field as the machine advances, so they must be collected after harvesting is complete. .

Since the work of transporting these grain culms one by one to the threshing work position is extremely labor intensive, a hand-push cart is generally used to collect the grain culms.

However, this transport vehicle also cannot carry a large amount of cargo at one time, and having to transport the products back and forth several times is also a tedious task.

Therefore, it was proposed to attach a transporter to the binder and release the bound grain culms onto the transporter.
Since the transport machine requires a large space, it has many problems, such as making it difficult to steer the machine and making it impossible to harvest along the edges of ridges and banks.

The present invention was developed in view of the above points, and includes a frame mounted on a pair of left and right sleds, and a frame that is pivotally supported by the frame to allow for reverse-shaped transportation that can freely rotate between the transportation position and the release position. By forming a transport device with a stand and removably connecting this transport device to a self-propelled vehicle that has been removed from the binder, large quantities of harvested grain culms, etc., are quickly transported by the binder to the collection location. A grain culm transporter that makes it possible to release harvested grain culms, facilitates the transport work of harvested grain culms, saves labor, and improves the annual operating rate by allowing the traveling vehicle to be used for both harvesting and transport work. It provides:

Embodiments of the present invention will be described in detail below with reference to the drawings.

Figures 1 to 3 show an embodiment of the grain culm carrier according to the present invention, where Figure 1 is a side view of the carrier, Figure 2 is a rear view, and Figure 3 is a side view of the grain culm carrier. It is a diagram.

In these figures, the carrier, designated as a whole by reference numeral 1, is equipped with a pair of left and right sleds 2 made of wood and shaped like a boat. A frame 6 having a triangular shape in side view is mounted and fixed to the sled 2 by a horizontal member 3, an inclined member 4, and a connecting frame 5 having a U-shaped cross section.

On the other hand, the transport platform 7 is shaped like an inverted character by surrounding pipe materials and plate materials attached thereto, and the frame 6
It is pivotally supported by a support plate 8 provided on an inclined member 4, and is configured to be freely rotatable between a load carrying position shown by a solid line in FIG. 1 and a discharge position shown by a chain line.

Further, among the U-shaped members of the carrier 7, the member 7a on the front side in the direction of movement of the machine is fan-shaped so that the width becomes wider toward the tip.

Further, the lower part of the rear member 7b of the carrier 7 is connected by an angle iron 7C, and a handle shaft 9 is rotatably attached to a pair of left and right bearings tri7d protruding from the angle iron 7C. The handle is supported by a shaft, and one end is bent into an L-shape to form a handle.

A locking fitting 11 having a hook portion that engages with a locking plate 10 fixed to the upper end of the connecting frame 5 is attached to the handle shaft 9. Bearing plate 7
A torsion coil spring 1 which biases the handle shaft 9 to rotate in the direction of engaging the locking fitting 11 with the locking plate 10 is provided between the locking member 11 and the locking plate 10.
2 is installed.

By doing this, when the transport platform 7 is rotated clockwise in FIG. It rotates slightly against the resistance, and then engages with the locking plate 10 to restrict the rotation of the carrier 7.

On the other hand, the vehicle 13, which is generally designated by the reference numeral 13, is detachably connected to a binder (not shown) and is separated from the binder and becomes independent. , a connecting plate 15 fixed to both left and right sides of the lower end thereof, a gear box 16 integrally attached to one connecting plate 15, and a bearing integrally formed with the other connecting plate 15 (Fig. (not shown), and running wheels 18 are rotatably attached to an axle 17 that is rotatably supported by the lower end of the gear box 16 and a bearing.

The vehicle 13 is also equipped with an engine 19, and the output shaft of the engine 19 is drivingly connected to an input shaft 20 at the upper end of the gearbox 16.

The input shaft 20 is configured to be connected to a drive shaft by a belt to drive the binder when the traveling vehicle 13 is connected to the binder.

The traveling vehicle 13 and the transport device 1 are collectively designated by reference numeral 2.
They are detachably connected by a connecting mechanism indicated by 1.

That is, a pair of upper and lower pins 22 are removably inserted into the connecting frame 5 on the transport device 1 side, while the front end of the connecting plate 15 on the traveling vehicle 13 side is engaged with these pins 22. A notch is provided.

Furthermore, an L-shaped gripping lever 24 is pivoted in the hollow portion of the connecting plate 15 and is biased by a tension spring 23 to rotate clockwise in FIG. The lower pin 22 is held between the notches.

Note that the binder (not shown) is also provided with a connecting frame 5 similar to that provided in the carrier 1.

The operation of connecting the traveling vehicle 13 and the carrier 1 constructed as above and the operation of transporting grain culms will be explained.

First, the gripping lever 24 is rotated against the elastic force of the tension spring 23 to open so that the pin 22 can be gripped by the notch in the connecting plate 15, and then the gripping lever 24 is attached to the connecting plate 15. Rotation is locked by engaging with a notch (not shown).

In this state, hold the handle 14 to tilt the traveling vehicle 13 forward, insert the connecting plate 15 between the upper and lower pins 22, and then raise the traveling vehicle 13. When the notch in the connecting plate 15 and the upper pin 22 are raised, is engaged.

When the holding lever 24 is released, the lower pin 22 is supported by this lever and the notch in the connecting plate 15, so that the traveling vehicle 13 and the carrier 1 are completely connected.

After the connection is made in this way, the engine 19 is started and the machine base is made to travel along the mowing marks in the field.

In this case, since the grain culm transporter is capable of self-propelling in a straight direction using the running wheels 18 and the sled 2, the operator is positioned to the side of the running vehicle 13 and uses one hand to control the direction of movement of the machine. It is possible to load the harvested grain from the field onto the carrier 7 with the other hand with slight corrections.

In this manner, the machine is run while collecting the harvested grain culms, and when the transport platform 7 is fully loaded with grain culms, the machine is moved, for example, to a collection area near the threshing machine.

Then, when the handle shaft 9 is rotated against the elastic force of the torsion coil spring 12 to disengage the locking metal fitting 11 and the locking plate 10 and rotate the carrier 7, the carrier 7 is rotated. The upper grain culm is immediately discharged to the dump.

In addition, during transportation, by forming the transport platform 7 in an inverted shape and forming its front member 7a in a fan shape, a large amount of grain culms can be loaded without the cargo collapsing. .

When the transport platform 7 is returned to the transporting position after releasing the grain culm, when the rear side member 7b is gripped and rotated, the locking metal fitting 11 comes into sliding contact with the upper surface of the locking plate 10. Since they are engaged, the carrier 7 can be laid down and locked with a single touch.

Note that this grain culm transporter can also be used for transporting not only harvested grain culms but also waste straw.

As is clear from the above explanation, according to the present invention, there is a frame mounted on a pair of left and right sleds, and an inverted letter-shaped frame that is pivotally supported by the frame and can freely rotate between the carrying position and the releasing position. By forming a transport device with a transport platform and removably connecting this transport device to a self-propelled vehicle that has been removed from the binder, it is possible to load a large amount of harvested grain culms, etc., and to generate power. Since it is possible to transport the loaded items very efficiently using the system, and the loaded items can be extremely easily discharged to the collection site, it is possible to significantly save labor in agricultural work.

Further, since the drive machine connected to this grain culm transporter can also be connected to the reaping section of the binder, etc., the annual operating rate of the drive machine is improved.
