Description

[Detailed Description of the Invention] The present invention relates to a rough sorting machine for sorting out grains mixed with impurities.

Conventionally, in this type of rough sorting machine, the grains supplied from the supply funnel were supplied to the upper part of the swinging sorting shelf from a single supply port provided at the bottom of the sorting shelf, so the processing of the grains was difficult. When there was a large amount of grain to be harvested, a thick layer of grain would form on the screen of the swinging sorting rack, and branches and straw debris would pile up and get tangled, making grain sorting difficult.

In view of this point, the present invention provides a sorting shelf below the supply funnel, a swinging sorting shelf below the sorting shelf, and a supply port on one side of the swinging sorting shelf in the sorting shelf. Since the auxiliary supply port is provided in the center, the layer thickness of the grains is distributed thinly, and the sorting area of the swinging sorting shelf is wide, which prevents foreign matter such as branches and straw waste from getting entangled. The present invention aims to provide a rough sorting machine that can improve the sorting ability.

A preferred embodiment of the present invention will be described in detail below with reference to the drawings.

In the figure, a feed funnel 5 is provided at the upper part of a frame 2 of a rough separator 1 in communication with a feed port 3 for feeding grains.

Further, a feed roll 7 for feeding out grains is rotatably attached to the lower part of the supply funnel 5.

Furthermore, a discharge port 11 is provided at the lower part of the sorting racks 9, 9 provided at an angle facing each other below the feed roll 7, and the grains falling from the feed roll 7 are discharged downward.

Further, a supply port 15 is provided at the lower part of a handling shelf 13.13 provided at an angle opposite to the bottom of the discharge port 11.

Opposed to the lower side of the supply port 15 is one side of a swingable sorting shelf 17 which is tilted appropriately and is swingable.

On the swing sorting shelf 17, a first sorting net 19 for preliminary sorting is provided parallel to the inclination direction, and a second sorting net 21 for finishing sorting is provided below the first sorting net 19 in parallel.

A plurality of auxiliary supply ports 20 are provided near the inclined central portion of the first sorting net 19, which communicate with the sorting shelf 13 on the right side in FIG.
, 20. ...is provided.

At the lower part of the slope of the first sorting net 19, a discharge groove 23 for discharging straw waste not sorted by the first sorting net 19 is provided in a direction substantially perpendicular to the direction of inclination of the swinging sorting shelf 17. A discharge tube 2 is connected to the distal end of the discharge groove 23 and communicates downward.
5 is provided.

Furthermore, at the lower end of the intermediate slope between the first sorting net 19 and the second sorting net 21, there is a
A discharge tube 27 for discharging straw waste etc. that has not been sorted by the sorting net 21 is provided in communication.

Further, the grains that have passed through the second sorting net 21 and been sorted are discharged to the outside by a discharge pipe 28 through a sloped portion at the bottom of the swing sorting shelf 17.

A swinging device 29 for swinging the swinging sorting shelf 17 is attached to the lower part of the swinging sorting shelf 17, and swings by the power of a motor 31.

Further, an intake chamber 37 is provided adjacent to the supply funnel 5, and a relatively light amount of dust and the like mixed in the grains discharged from the outlet 11 is removed from the intake chamber 37 by an intake fan (not shown). It is discharged to the outside in the direction of the arrow.

Also, some of the lighter dust particles are conveyed by a conveyor helix 41, and from the end of the conveyor helix 41 is transferred to a discharge pipe 43.
It passes through and is discharged to the outside.

In the above configuration, the motor 31 is driven to operate the feed roll 7, the swing device 29, and the conveyance helix 41.

The grains supplied from the supply port 3 pass through the supply funnel 5 and the feed roll 7, fall from the discharge port 11 onto the handling rack 13.13, and slide down the slope of the handling rack 13.13. are supplied to the upper part of the first sorting net 19, and are also supplied to the auxiliary supply ports 20, 20, of the sorting shelf 13. ... and is supplied to approximately the center of the first sorting net 19.

The remaining straw waste that has not passed through the swinging first sorting net 19 is carried by the discharge groove 23 and discharged to the outside by the discharge pipe 25.

In addition, relatively light pieces of straw and dust mixed in with the grains discharged from the discharge port 11 are sucked by the suction force of a suction fan (not shown), sent to the conveying helix 41, and passed through the discharge pipe 43. Other lighter straw, dust, etc. pass through the suction chamber 37 and are discharged to the outside and treated.

On the other hand, the first sorting net 19 passes through the net, is sorted, and the second
Among the grains and straw waste that have fallen onto the sorting net 21, the straw waste that has not passed through the second sorting net 21 and has not been sorted is discharged to the outside through the discharge tube 27 along the slope and is disposed of.

Further, the grains that have passed through the second sorting net 21 and been sorted are discharged to the outside from the discharge pipe 28 through the inclined part and are processed.

FIG. 2 shows several auxiliary supply ports 20, 20, and 20 provided in communication with the handling shelf 13 (on the right side in FIG. 1). It is an explanatory diagram showing ..., and the arrow indicates the distribution direction of grains.

As explained above, according to the configuration of the present invention, the grains fed from the supply funnel are guided by the sorting shelf provided below the supply funnel, and are further shaken by the plurality of supply ports provided on the sorting shelf. Since grains can now be discharged to one side of the movable sorting shelf and to the center thereof, the grains will not be concentrated on one side of the movable sorting shelf, and the grains will be separated by the swing of the movable sorting shelf.
Since grains can be spread thinly and distributed between the - side and the center side, the accuracy of grain sorting is improved.

In addition, since the grains are spread thinly and distributed, the area of the swinging sorting shelf can be utilized to a large extent, so entanglements caused by foreign matter such as branch stems and straw waste can be prevented, and the sorting ability can be improved.

It should be noted that the present invention is not limited to the above-mentioned embodiments, but can be implemented in other embodiments as well.
