Description

[Detailed Description of the Invention] The present invention relates to a spill prevention structure for a wagon device that prevents the stored harvest from falling out when the harvest is transferred to another vehicle.

As a harvesting machine for maize or forage, there is one that has a harvesting device attached to the rear of a reciprocating tractor and a wagon device mounted on the front bonnet.

This type of wagon device collects a large amount of harvested products stored in a wagon and transports them using a farm wagon or other vehicle such as a truck.This type of wagon device rotates the wagon upward around the discharge port side to collect the harvested products. It is configured so that it can be transferred to the loading platform of another vehicle.

In such a wagon device, it is difficult to bring the wagon discharge port into complete contact with the loading platform of another vehicle, and a gap is created between the two, which may cause crops to fall out during transfer.

In view of these conventional problems, the present invention provides a flexible spill prevention member at the discharge port of the wagon, and allows the tip of this spill prevention member to be inserted into the loading platform of another vehicle. To provide a spill-preventing structure for a wagon that enables reliable transfer of harvested crops without spilling them.

A feature of the present invention for achieving this purpose is that the upper end of the crop storage wagon 16 on the discharge port A side is pivoted around a horizontal shaft 27, and the wagon 16 is rotated upward around the horizontal shaft 27. In the wagon device, the harvested product can be discharged and transferred to the loading platform 36 of another vehicle by discharging the harvested product. A spill prevention member 41 having flexibility that can be hung is provided on the outside of the discharge port A side of the goods storage wagon 16.

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

In the first embodiment shown in FIG. 1, 1 is a tractor as a traveling vehicle, and a vehicle body 5 is composed of an engine 2, a transmission case 3, a front axle frame 4 protruding forward from the engine 2, etc. A vertical frame 6 installed approximately at the center of the frame 5 in the front and back direction.
and the front axle frame 4 etc., the engine 2
A bonnet 7 surrounding the radiator is attached, and the rear side of the vertical frame 6 serves as a control section 8. Reference numeral 9 indicates a front wheel as a steering wheel, and numeral 10 indicates a rear wheel as a driving wheel.

The seat 11 and handle 12 of the control section 8 can be rearranged between a forward facing position (phantom line in FIG. 1) and a rearward facing position (solid line in FIG. 1), thereby making the tractor capable of switching forward and backward movement.

A harvesting device such as a maize harvester is attached to the rear of the tractor 1 via a three-point linkage mechanism, and only the tip of the chute 13 of the maize harvester is shown in FIG. The wagon 16 extends upward and is mounted on the top of the bonnet 7 so that maize (harvested product) can be thrown into the wagon 16.

The wagon device 15 is a wagon 16 that stores maize.
A support mechanism 17 for mounting the wagon 16 on the tractor 1 and rotatably supporting it; a stand mechanism 18 for separating the support mechanism 17 from the tractor and erecting it; It has a scattering prevention mechanism 19 that prevents maize entering the wagon 16 from scattering.

The support mechanism 17 includes a pair of front and rear mounting brackets 21 from the vertical frame 6 and the tip of the front axle frame 4.
is removably protruded upward, and each mounting bracket 2
A support rail 22 having an L-shaped cross section is fixed between the upper ends of the bonnet 7, and a support frame 23 connected left and right in front of the bonnet 7 is slid and placed from the front end of the support rail 22. ,2
5 is provided protrudingly, and a guide plate 26 is provided on the upper surface thereof.

The upper ends of the front and rear struts 24 and 25 are overlapped,
A bracket 28 at the front upper part of the wagon 16 is connected to this overlapping portion via a horizontal shaft 27 so as to be rotatable about the horizontal shaft.

The wagon 16 has a bifurcated lower part, and is mounted and supported on a support frame 23 via a cushion material, straddling the upper part of the bonnet 7. This is to regulate the position in the direction.

Reference numeral 35 denotes a hydraulic cylinder provided between the support frame 23 and the upper part of the wagon 16, which, when activated, rotates (dumps) the wagon 16 upwards around the horizontal axis 27, and dumps the harvest in the wagon 16. The loading platform of another vehicle such as a farm wagon or truck 3
Transferred to 6.

A tilt 37 is arranged at the rear upper part of the wagon 16 to prevent the input crop from scattering forward. This tilt 37 is attached to the front end of a support link 38 that is pivotally supported on the left and right upper portions of the wagon. The rear end of the support link 38 and the support column 25 are connected to the connection link 3
9, and as the wagon 16 rotates upward, the tilter 37 is configured to move upward away from the front upper part of the wagon, thereby preventing the harvest from being discharged from the wagon. It's summery. Note that it is preferable that the tilt 37 be foldable with respect to the support link 38.

The base of a spill prevention member 41 is attached to the discharge port A at the front upper part of the wagon 16 via a bracket 40. This spill prevention member 41 is formed into a sheet shape from a flexible material such as rubber or cloth, and has a width that spans the entire width of the wagon.
1a is sufficiently long from the horizontal axis 27 toward the front (backward in the working direction).

When transferring the crops in the wagon 16 to the loading platform 36 of another vehicle, after bringing the loading platform close to the wagon,
The tip 41a of the spill prevention member 41 is inserted and arranged. The spill prevention member 41 hangs down from the discharge port A and closes the gap between it and the loading platform 36.

After setting in this way, the hydraulic cylinder 35
When the wagon 16 is rotated upward around the horizontal shaft 27, the harvested material is discharged from the discharge port A, guided by the spill prevention member 41, and transferred to the loading platform 36, where it is connected to the discharge port. This prevents spillage from falling between the container and the loading platform.

Harvest is transferred from the wagon side in the loading platform, and
As shown in the imaginary line in the figure, the spillage prevention member 41 is piled up, but if the wagon 16 is moved up significantly, the spillage prevention member 41
This presses down the heaped harvest from the outside and above, preventing the heaped harvest from spilling over the upper edge of the loading platform 36 and out of the loading platform. The bracket 40 for installing the spill prevention member is attached to the wagon 1.
If it largely protrudes from the upper edge of 6, spillage of the piled crop can be more reliably prevented.

Since the spill prevention member 41 has flexibility, even if the loading platform is higher than the horizontal axis 27 or the bracket 40, the spill prevention member 41 can extend over the upper edge of the higher loading platform and reach the tip 41a.
It is possible to insert and arrange the inside.

In the first embodiment, since the spill prevention member 41 is free with respect to the loading platform 36, the tip 41a can move up and down as the wagon 16 moves up and down.
Although it is easy to work with and does not cause sagging, if the cart is far away from the wagon, it may sag in the middle, or the sag may be pulled out of the loading platform due to its own weight.

The second device is configured to prevent this pulling out and ensure that the tip 41a is placed inside the loading platform 36.
This is the spill prevention member 41' of the embodiment.

In FIG. 2, the spill prevention member 41' has a magnet 4 at its tip 41a that can be magnetically attached to the inner surface of the loading platform 36.
3, and the tip 41a is substantially fixed to the loading platform 36 via the magnet 43, so it will not come out even if the weight of itself or the weight of the harvest is added midway through.

The magnet 43 is attached to the tip of the spill prevention member via a rubber member that can be pulled sufficiently.
The rubber member may be stretched to bridge the spill prevention member to the cargo platform. Further, the base of the spill prevention member 41 may be screwed or glued to the upper edge of the wagon 16 without providing the bracket 40, but if it is attached to the bracket 40, the harvest will be discharged more smoothly and the harvest will not be piled up. This is preferable because it also allows you to control the condition.

According to the present invention described in detail above, the spill prevention member 41 having flexibility is provided at the discharge port A, and the spill prevention member 41 is placed over the horizontal shaft 27 from above to cover the discharge port A of the crop storage wagon 16. Since it can be hung outward from the side, by inserting the tip of the spill prevention member 41 into the loading platform when transferring the harvest, the harvest discharged from the wagon 16 is guided to the spill prevention member 41. The container can be transferred reliably without spilling between the container and the loading platform. Moreover, since the horizontal shaft 27 can be covered from above by the spill prevention member 41, the horizontal shaft 27 may prevent the smooth transfer of the harvest during harvest transfer, or the harvest may be moved horizontally. There is no possibility of the product hitting the shaft 27 and spilling outside, and from this point of view, the harvest can be transferred even more reliably and smoothly.
