Description

[Detailed Description of the Invention] The present invention relates to a lifting device (thrower) for lifting grains, etc.

With the development and spread of agricultural machinery such as combine harvesters and harvesters, it has become necessary to intensively process large amounts of paddy and shredded waste straw for feed.

For this reason, a lifting device (thrower) is used, for example, to transport a large amount of threshed paddy to a drying device or a paddy storage, or to transport and store shredded waste straw in a silo or the like. As mentioned above, transport using this thrower also requires quantitative processing, so
Feeding paddy etc. to the lifting section through a normal supply hopper is inefficient.

Therefore, making the opening of the hopper large will disrupt the balance of the entire lifting device, and the inclination angle of the guide bottom plate of the hopper will have to change slowly, resulting in a lack of smooth supply to the lifting action section. There is.

The present invention was developed in response to these circumstances, and the case that constitutes the lifting device can be tilted and fixed to the side opposite to the side where the supply hopper is located, and both sides of the hopper can be expanded and contracted. Furthermore, the front part of the hopper is connected to the board by a continuous rod, and the opening of the hopper automatically expands when the case is tilted, greatly changing the storage capacity of the hopper. The aim is to rationally resolve the uneconomical and inefficient effects of increasing the size of the machine.

To explain the details of the embodiment with reference to the drawings, 1 is a round flat case, and inside this case 1, a disk 4 is attached to the end of a drive shaft 3 which is mounted on the center of the case rear wall 2. A plurality of blades 5 are fixed to the outer periphery of one side of the disk 4 at equal intervals.
In the case 1, a lifting cylinder 6 lifts and conveys grains etc. to another place by the lifting force generated by the rotation of the blades 5.
It is integrally formed on one side in the centrifugal direction.

The back wall 2 of the case 1 is fixedly supported by a horizontal beam 7, and both ends of the beam 7 are rotatable in one direction, with both ends pivoted on a board 8, as shown in FIG. A base plate 10 is fixed to the downward U-shaped holding frame 9 and provided on the upper side of the holding frame 9.
A motor 11 is mounted on the top.

A pulley 13 provided on the shaft 12 of the motor 11 and a pulley 14 provided at the outer end of the drive shaft 3 are connected by a belt 15. The above holding frame 9
A tightening bolt 16 is provided at the lower part of both vertical rod portions of the substrate 8, and the tightening bolt 16 is inserted into an adjustment slot 18 formed in a support rod 17 whose lower end is pivoted on the rear end of the substrate 8.
The support rod 17 supports the load when the holding frame is rotated in one direction, that is, when it is tilted backward, and the tilting angle of the holding frame is maintained by the support rod 17.

The front wall 19 of the case 1 is provided with an opening 20 for guiding grains etc. to the lifting action section inside the case, and the right and left sides of a frame 21 attached to the front wall 19 surround this opening 20. Hopper 22
One side edge of the fan-shaped plate 23 for forming the
Along the inner surface of the frame 21, fan-shaped plate portions 25 are slidably placed upright on both sides of the guide bottom plate 24 constituting the hopper. The upper ends of extendable and adjustable connecting rods 26 are connected to the front ends of both fan-shaped plate parts 25, and the lower ends of the connecting rods 26 are connected to the front edge of the base plate 8, respectively. It is something.

In the figure, reference numeral 27 denotes a regulating plate for feeding objects such as grains into the case, and this regulating plate 27 is used to quantify the amount of material to be fed into the case, so that smooth lifting and transportation can be achieved.

The reason why the disk 4 to which the blade 5 is attached is not made into an arm shape is to prevent grains from accumulating on the inner surface of the rear wall 2 of the case when the case is tilted, making it impossible to lift the case.

Next, to explain the operation, the tightening bolt 16
After loosening the holding frame, that is, the thrower is tilted to the rear side at an arbitrary angle, the tightening bolt 16 is tightened again to hold the thrower in the tilted state. At this time, the fan-shaped plates 23 in the overlapping state slide together with the case, and the input port of the hopper 22 is opened wide.

However, as shown by the imaginary line in FIG.
Since the angle of the guide bottom plate 24 with respect to the front wall 19 of the case changes to a pure square shape, which results in obstructing the natural flow of grains, etc., the connecting rods 26 are extended as necessary. Adjust the angle with respect to. Even if the thrower itself is tilted,
Since the motor 11 is fixed to the holding frame 9, there is no problem with the transmission drive, and grains and the like can be lifted and transported smoothly in the same manner as in the upright state.

As described above, according to the present invention, the case can not only be used vertically, but also when it is necessary to feed a large amount of material into the hopper, the case itself can be used in the opposite direction from the side on which the hopper is attached. By tilting to the side, the opening of the hopper can be automatically expanded and the storage capacity of the hopper can be increased. In this way, the volume of the hopper can be freely changed depending on the object to be lifted, and the lifting operation can be carried out uniformly, which is a great practical effect.
