Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to improvements in temporary storage tanks mounted on harvesters.

[Prior Art] Root vegetables such as potatoes are harvested by a harvester. When harvested, they are first stored in a temporary storage tank mounted on the harvester, and then transferred from the tank to bags, containers, truck beds, etc. removed or deposited on the ground. Therefore, in order to discharge the harvest from the tank quickly and without damaging it, it is necessary to adjust the attitude of the tank to the conditions at the destination.

Since the posture of conventional tanks was adjusted using hydraulic cylinders installed on the front, back, left, and right sides of the bottom, it was only possible to raise the tank as it was or to lift the discharge end. The discharge end of the tank can be raised high to discharge the crop onto a loading platform, or the discharge end of the tank can be raised to the ground to efficiently load the crop into bags, or to allow the crop to fall to the ground without damaging it. It was impossible to lower it any closer.

[Problems to be Solved by the Invention] The present invention has been made in view of the above, and its purpose is to lift the discharge end considerably high and discharge the harvest into a container or truck bed with a high side plate. Another object of the present invention is to provide a tank whose discharge end can be lowered close to the ground surface.

[Means for Solving the Problems] In order to achieve the above object, the features of the present invention are such that a first support is fixed to the machine frame, and a second support is slidable vertically on the first support. The tank is rotatably supported on the second column, a lifting hydraulic cylinder for sliding the second column is provided on the machine frame, and a tilting hydraulic cylinder for rotating the tank is installed between the second column and the tank. This is because it was established in

[Action] If you extend the lifting hydraulic cylinder to raise the tank together with the second column, and then shorten the tilting hydraulic cylinder to tilt the tank, the discharge end will rise quite high, so it will not work on the high side panels of containers or truck beds. It can be placed inside the discharge end.

If you extend the tilting hydraulic cylinder and tilt the tank without raising the tank, or after raising it slightly using the lifting hydraulic cylinder, the tank's discharge end will be lowered to near the ground surface, making it possible to efficiently harvest crops. You can also load it into your bag.
It is also possible to deposit crops on the ground without damaging them.

When loading crops into containers or truck beds with low sides, only the lifting hydraulic cylinders need to be extended.

After leveling the tank and filling the tank with the harvested material to the maximum limit, the tank is either not raised or raised slightly using the lifting hydraulic cylinder, and then the tilting hydraulic cylinder is shortened so that the discharge end of the tank is raised. Tilt it. If the crop is subsequently added to the tank in this way, the crop in the tank will be leveled out, so that the tank will be full without leaving any voids.

[Example] A tank of the present invention will be explained based on an example shown in the drawings.

As shown in Figures 2 to 4, the potato harvester is equipped with a digging blade 12 on the underside of the machine frame 1O, and a first conveyor 14 follows behind the digging blade. A sorting conveyor 18 from the rotary conveyor 16 to the tank 20 is installed on the upper side of the zero machine i10 where the rotary conveyor 16 is located at the rear. It can also be removed. The potatoes dug up by the digging blade 12 are transferred from the first conveyor 14 via the rotary conveyor 1B to the sorting conveyor 18, and then temporarily stored in a tank 20. A bottom conveyor 21 is arranged at the bottom of the tank 20. The tank 20 is supported by a strut 30 attached to the machine frame IO.

The discharge part 20a of the tank 20 is connected to the hydraulic cylinder 1 in FIG.
When rod 9 is retracted, it protrudes to the side of the harvester as shown by the chain line. A bottom container 21 is also provided at the bottom of the discharge section 20a. This bottom conveyor is run by a hydraulic motor to remove the potatoes in the tank 20 from the discharge section 20.
Discharge from a to bags, containers, truck beds, the ground, etc.

As shown in FIG.
0 is fixed, and a second support 32 is inserted into the inside of that support so as to be movable up and down. A lifting hydraulic cylinder 34 extending parallel to the first column 30 is fixed to the machine frame 10, and a rod of the hydraulic cylinder 34 is integrally fixed to the second column 32 via the bracket 3B. A receiving plate 38 is fixed to both the front and rear sides of the tank 20, and the receiving plate 38 is swingably supported by the second column 32 via a pin 40. The cylinder of the tilting hydraulic cylinder 44 is pinned to the bracket 42 fixed to the second support 32, and the rod of the hydraulic cylinder 44 is pinned to the bracket 4B fixed to the tank 20. When the hydraulic cylinder 44 is extended or contracted, the tank 20 tilts left and right about the pin 40.

As shown in FIG. 5, the cross sections of the first support 30 and the second support 32 are in the shape of opposite sides, and the cross sections of the first support 30 and the second support 32 are cross-sectional.
A guide wheel 50 that fits inside the second support column 32 is attached to the second end via a pin 52. A rod of a lifting hydraulic cylinder 34 is pinned to a bracket 36 fixed to the second support 32. A pin 40 is fixed to the center of the second column 32, and the pin fits into a bearing portion 39 of a receiving plate 38, so that the receiving plate 38 is integrally fixed to the tongue 20.

As shown in FIG. 6, a guide wheel 54 whose diameter is slightly smaller than the inner width of the first support column 30 is attached to the lower end of the second support column 32.
Attached via 6. Therefore, the first strut 32 slides smoothly and stably along the inner surface of the strut 30.

Next, the operation of the tank of the present invention will be explained. As shown by the chain line in FIG. 7, if potatoes are stored with the bottom of the tank 20 horizontal, the potatoes in the tank 20 will accumulate in a mountain shape, so it is impossible to store the potatoes in the tank while leaving an empty space on one side. limit reached. Therefore, as shown by the solid line in Figure 7,
After the tank 20 is slightly raised by operating the lifting hydraulic cylinder, the rod of the tilting hydraulic cylinder 44 is retracted to tilt the tank 20. Then, when the tip of the first sorting conveyor 18 is also raised and the potatoes are put into the tank 20,
Since the potatoes fill the void on one side, the tank 20 will be full without leaving any void.

As shown in FIG. 8, when the rod of the tilting hydraulic cylinder 44 is extended, the discharge end of the tank 20 is lowered.
The head difference between the discharge end and the ground surface becomes smaller.

Therefore, damage to potatoes discharged to the ground can be reduced. At this time, the tank may be raised slightly in advance.

As shown by the chain line in FIG. 9, the potatoes in the tank 20 are discharged into a container or truck bed.

The rod of the lifting hydraulic cylinder 34 is extended and the tank 2
0, but the side plate 60 of the container or truck bed
is higher than the discharge end of the tank 20, the discharge end cannot be placed inside the container or truck bed as it is. However, if the rod of the tilting hydraulic cylinder 44 is retracted to tilt the container 20 and lift the discharge end, the side plate 60 of the container or truck or cargo platform can be brought closer to the harvester. Go inside a container or truck bed. Therefore, potatoes can be loaded even into a container with a high side plate 60 or a truck bed.

[Effects of the Invention] As described above, the tank of the present invention ascends and descends along with the second column that is lowered along the first column fixed to the machine frame, and tilts around the pin fixed to the second column. Similar to conventional tanks, containers with relatively low side panels can be tilted to fill the tank with the harvest stored in the tank, or the tank can be placed parallel to the container with relatively low sides. Not only can the harvest be discharged onto the truck bed, but also
It is also possible to lower the discharge end of the tank below the machine frame and discharge the harvest into the ground or into a bag with a low head, which was impossible with conventional tanks. It has a special effect in that it is possible to tilt and lift the discharge end to discharge harvested products into a container or truck bed with high side panels.
