Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention provides a method for transporting crops, especially crops from sugarcane fields.
Concerning crop transport used with sugar cane harvesters to transport cut sugar cane to containers for transport to processing plants.

[Prior art and its problems]

When harvesting sugar cane using mechanized operations,
Crops are cut into so-called billets that are easy to transport and process by cutting them with a harvester. These billets are discharged by the harvester to a field transporter, which carries containers that can be individually transferred from the field transport vehicle to a second transport device called a mill transporter. be. The mill transporter then moves these pellets from the field location to the factory.

Alternatively, the field transporter may have one or more tiltable containers.

In that case, when the container is tipped, the billet is discharged into a series of containers carried by a mill transporter, which distributes it to the processing plant.

Actual work using existing field transport machines is inefficient. If a transportable container is used, place one box on the mill transporter and transport it in the field.
! It takes a long time to unload the replacement box. Further, two workers are required, or in the case of one worker, the worker must get off the vehicle, which results in a loss of time. Furthermore, if the container on the field transport machine is not full, the container will be transported to the factory as is.

Additionally, there is no flexibility in loading and unloading portions of billets when using field transport containers that can tilt. This also has the inconvenience of having to transport unfilled bags to the factory.

In any case, since it is necessary to correctly position the transporter before unloading, the time required for unloading the traveling body is inefficient and takes a considerable amount of time, and in fact, the loading and unloading work itself takes time.

Further disadvantages arise due to the high weight 8 of existing field transporters. In the case of a tractor-trailer combination, the tractor must be ballasted to provide traction for the drive wheels. The need for such ballast is reduced or eliminated if the field transporter has its own payload, thus allowing for a lighter machine design.

[Embodiments of the invention]

The present invention will be described in detail below based on the drawings.

In FIG. 1, luck mi is shown as 10. This transporter 1
0 consists of a chassis 11, a crop container 12 and a pivot frame 13 mounted between the crop container 12 and the chassis 11.

Four low-pressure, high-buoyancy tires 14 are mounted on the front and rear axles 20, 21 of the chassis 11, as shown in FIG. The axle 20 pivots about a first axis 40 and is steerable about a second axis 26 perpendicular to the first axis 40. The rear axle 21 is fixed to the chassis 11. An operator console 22 and power source 23 for the transporter 10 are also mounted on the chassis 11 (FIG. 1).

The pivot frame 13 utilized between the chassis 11 and the crop container 12 is shown in detail in FIG. It consists of a turntable assembly 24 rotatable relative to the chassis 11. A pair of pivot arms 30 are connected between turntable assembly 24 and crop container 12.

Pivot arm 30 is bin mounted for rotation about pivot axis 52 relative to crop container 12 .

A pair of hydraulic cylinders 31 are pivotally mounted between the pivot arm 30 and the crop container 12. Another hydraulic cylinder 25 is connected between the chassis 11 and the turntable assembly 24 to permit relative movement of the crop container 12 with respect to the chassis 11 about the turntable axis 54.

A crop conveyor assembly, generally designated 32, is mounted within crop container 12 as shown in FIG. The crop conveyor assembly 32 is a slat type conveyor consisting of a number of platelets or slats extending across the width of the crop container 12 between conveyor chains 42. The chain 42 moves around the drive sprockets 1 to 33 on the front shaft 36 and the idler sprocket 34 on the rear shaft 46.
(not shown) are supported by upper and lower runners 43 and 44, respectively. Drive sprocket 33 is hydraulically driven and controlled by an operator. Another such runner 51 is provided at the rear of the crop container 12 to create an angular change at the change point T so that the conveyor chain 42 follows the shape of the bottom of the crop container 12 correctly.

Container 12 is moved to turntable assembly 2 for unloading.
4, the conveyor assembly 32 shown in FIG. 7 is used.

This conveyor increases the stability of the wheels during unloading.

In this embodiment, the slats 50 are intermittently mounted between the chains 42 at the front of the container 12.
It extends across the width of the space.

However, at the rear of the container 12 the last slat 55 at the front and the first slat 60 after the last slat 50
There is a gap between. This spacing is predetermined by the time required for the last slat 55 to release all of its front load and for the slat 60 to begin advancing the rear load of the container 12.

If this conveyor 32 is used for side unloading, the operator should know that the conveyor assembly 32 is in the correct stop position before loading so that proper slat spacing can be obtained during unloading. It is necessary to provide a signal to the operator of the transporter 10.

To do this, the slats 65 near the drive sprocket 33 are fully visible from the operator console 22 and painted red for easy identification and are therefore easily visible to the operator and correct for stopping. It can be manipulated until the position is reached.

As shown in FIG.
1 serves to lock the front axle 20 of the transporter 10 in a lateral position. A reciprocating hydraulic piston 62 extends between a bracket 66 secured to the chassis 11 and the front axle 20.

Hydraulic pump 63 supplies fluid to circuit 61 as well as other hydraulic components on transport machine 10. The fluid pressure circuit 61 includes a manually operated four-way valve 64. In the position indicated by 2, the acid axle 20 is in the locked position. The valve 64 is adjusted to either side in its locking position, designated 1 or 3, so that the angle of the front axle 20 relative to the chassis 11 is manually varied by changing the position of the piston 62. With the valve 64 in the low position indicated by 4, the axle 20 is free for imaging when driving on a bumpy road.

In case of emergency in difficult terrain, the locking position M2 of the axle 20 is used to ensure stability.

Next, the operation of the crop transporting machine according to the present invention will be described. First, it is assumed that the transporting machine 10 is in a state of receiving billets from a sugar cane harvesting machine (not shown) in the field. In this operation, the transporter 10 is in the state shown in FIG. 1 and follows the harvester at the position shown by the solid line in FIG. 4. In other words, luck! The two aircraft 10 will have the crop container 12 facing forward and in its lowest position. Of course, the crop conveyor assembly 32 remains stationary during loading.

When the crop container 12 becomes full, Luck 1 [10 moves to the unloading location. Here, it is assumed that the transporter 10 first unloads the load as shown in FIG. 4 at the straight forward position, that is, the position shown by the solid line in FIG. Although the conveyor assembly 32 of FIG. 7 can be used with the container 12 in the forward unloading position, the conveyor of FIG. 6 will be used. Due to the height of the mill transporter (not shown), the hydraulic cylinder 31 is located at the console 2.
2 is activated by the operator. crop container 12
pivots upwardly about pivot axis 52 until it reaches its correct height, for example the height shown in FIG. The connecting structure between the pivot frame 13 and the crop container 12 is designed such that when the hydraulic cylinder 31 is extended, the maximum permissible inclination angle intended for billet unloading is not exceeded.

Once the crop container 12 has been raised to the required height, movement of the conveyor chain 42 is hydraulically initiated by the operator. The chain 42 moves in the direction not shown by the arrow in FIG. 6 and the slat 50 conveys the billet from the open front end of the crop container 12 to the container of the mill transport (not shown). Once the mill transport 1112R is full or filled to the desired level, the operator stops the operation of the conveyor assembly 32, thereby stopping the discharge of billets. Thus, the mill truck can be loaded to the desired filling state if its container is not full;
The field transporter 10 can then discharge its load to another container on the mill transporter if it is not already full.

If the operator wishes to unload the crop container 12 in a lateral position, such as that shown in dashed lines in FIG. 4 and in front view in FIG. 5), which rotates the turntable assembly 24 about the turntable axis 34 relative to the chassis 11 and therefore rotates the crop container 12 to the desired position. Once the desired lateral position is achieved, the operator actuates the hydraulic cylinder 31 to pivot the front of the crop container 12 upwardly as desired and as previously described. Once the crop container 12 is at the correct height in the desired lateral position, the operator will move the transporter 10 to the correct unloading position.

Conveyor 32 (FIG. 7) is activated and slats 50
moves the load to the front of the container 12 and releases it at the front end of the container 12. Because there is a spacing between the last slat 50 that contacts the load at the front of the container 12 and the next slat 60 that contacts the load at the rear of the container 12, the load at the front is less likely to be affected by the load at the rear. All or most of it is ejected as it moves towards the front end of the container 12 for ejection. In this way there is no instability or tendency to tilt which occurs when the load is concentrated in one part and moves towards the discharge end.

The hydraulic circuit of FIG. 9 can be utilized to improve stability due to side loading caused by crops within the combiner 12.

The operator manually moves the valve 64 to position 2, where the axle 20 locks and provides stability for the transport n10 during lateral unloading.

Following unloading from the container 12, the operator must reposition or stop the conveyor assembly 32 prior to loading the container 12 when the container 12 is to be unloaded in a side or pivoted position. This is facilitated by marking the slats 65 with red paint (Figure 7).

The slats 65 are fully visible from the operator console 22 when in the position shown, so that the operator need only drive the conveyor 32 until the slats 65 appear in the position shown. The transporter 10 is then ready for the next load.

A number of options are given for transport 1fi10. For example, this hydraulic circuit may be controlled by a pilot check valve and automatically inhibited by a hydraulic cylinder mounted to extend and retract with swinging of the front axle 20. This valve can be suitably controlled to stop movement of any axle relative to the chassis 11 if the crop container 12 is moved to a lateral position. At other times the valve allows free fluid movement and normal axle rocking. This pilot valve is for example crop container 1
The crop container 12 may be operated by a two-position valve controlled by a first position when the crop container 12 is in a straight-down position as shown in FIG. 1 and a second position when the crop container 12 assumes the other position.

A variety of drive options are also possible with Tanabata and brake units coupled to the machine's reduction hub for different operating conditions. Such options include 2 wheel drive, 4 wheel drive and 2/4 wheel drive for speed and maximum towing.

For example, two large variable hydraulic motors 70, 71 may be mounted on the contact wheels, and smaller fixed hydraulic motors 72, 73 may be mounted on the front wheels (FIG. 4).

When the transporter is operated at high speed, only the small motors 72 and 73 on the front wheels are operated, and when the transporter is operated at high torque and low speed, 4 motors are operated.
make all of the motors operate.

Of course, the pivot frame 13 or the turntable assembly 24 can also be used individually, without being combined. If only the pivot frame 13 is used, the operator can pivot the crop container 12 upward without pivoting. Also, when only the turntable assembly 24 is used, the operator cannot rotate the crop container 12 upwardly, but can. Of course, when using only the pivot frame 13, the hydraulic interlock axle motion limiter or modified conveyor of FIG. 7 is not required.

FIG. 10 shows another embodiment of the hydraulic actuation circuit.

Hydraulic cylinder 70 is connected to a hydraulic circuit that includes a locking valve 71 and a crossline pressure relief valve 72 between valve 73 and frame 72 so that locking valve 71 is automatically activated when container 12 is lifted.

Although the invention has been described with respect to particular embodiments, it is not limited thereto.
