Description

[Detailed description of the invention] The present invention relates to improvements in grain distribution devices for oscillating sorters.

In a conventional hulling sorting device equipped with a swinging sorter, a grain tank is suspended from the discharge port of an elevator installed on one side of the hulling device, and the mixed grains of paddy and brown rice stored in the tank are shaken. Since the system was designed to feed a sorting machine, the biggest drawback was that its installation area and volume were large in proportion to its capacity.

In order to eliminate the above-mentioned drawbacks, the present invention is an improvement of the grain distribution device of a related oscillating sorter, and in the oscillating distribution box provided in the lower part of the oscillating sorter, the above-mentioned The bottom wall of the distribution box is formed as a clear flow surface, and a grain leveling plate is mounted on the surface by being biased by a spring, and a plurality of discharge ports are provided on the discharge side of the clear flow surface. By integrally forming an oscillating grain trough connected almost perpendicularly to the supply side, and making the bottom wall of the grain trough a horizontal or gently sloped clear flow surface, the discharge side of the sorting board is improved. The distance between the rice huller and the hulling device installed at We have developed a grain distributing device for a oscillating sorter that streamlines the process in a concise manner, promotes miniaturization of the installation area and overall volume of the device, and facilitates high-efficiency sorting action. It is something to do.

The present invention will be explained with reference to embodiment figures. Reference numeral 1... is a swinging sorting board consisting of a plurality of rough surfaces, and the sorting board 1...
- is mounted on a swinging device 3 supported by a support 2 to form a swinging sorter 4, and on one side of the sorter 14 there is a rice husking room above a sorting air passage 5 consisting of a rice husk wind sorting flow down trough. The rice hulling chamber 6 is equipped with a rice hulling device 7 and integrally provided with a hulling and sorting process to form a hulling and sorting device. and inside it I]Rf
The f-rolls 9 and 9 are respectively mounted on a pair of parallel shafts 10 and 10 and mounted opposite each other so that one of them can be moved near and far with respect to the opposite shaft, and a sorting air passage 5 provided at the bottom thereof is arranged. It connects to the air exhaust machine 11, and the rice is removed in the hulling room 6, and the removed husks are air-sorted in the sorting air passage 5 and the rice husks are removed by the liter machine 11.
The mixed grains of paddy and brown rice that have been removed and wind-selected are sent through the transport conveyor 12 for paddy and brown rice provided in the downflow gutter, and then fried by the rice lifter 14 for paddy and brown rice provided at the discharge port 13 of the paddy and brown rice mixed grains. It is formed so as to be supplied to a swinging distribution box 15 provided at a lower part of the swinging sorting board 1.

Next, the swinging distribution box 15 is configured such that the bottom wall of the distribution box 15 is formed on a clear stream surface 16, and a grain leveling plate 17 is mounted on the surface 16 while being biased by a spring 18. A plurality of discharge ports 19 19 are provided on the discharge side of the clear flow surface 16, and an oscillating flow grain trough 20 is integrally formed on the supply side thereof in a substantially orthogonal manner, and the flow grain troughs 20 are integrally formed. A bottom wall 120 is formed as a horizontal or gently inclined clear stream surface 21, and 22 is a side wall surrounding the distribution box 14.

Claim (2) provides that the oscillating flow grain trough 20 of the distribution box 15 is connected to the mixed grain lifter provided at the paddy/brown rice mixed grain discharge port 13 of the hulling device 7 on the negative side thereof. Since it is connected to the curved rice feeding pipe 23 of the rice machine 14, an elevator with a suspended grain tank for mixed grains is installed and connected to the JIF exit section 13 of the conventional paddy/brown rice mixed grains, and the mixed grains are -H Compared to a sorting device that fried grain in the tank and supplied it to the distribution box of the sorting board,
The structure of the supply flow path for mixed grains of paddy and brown rice is simplified, reducing the manufacturing cost, and the height of the machine is lowered to keep the overall volume of the device as small as possible.

Because of the above configuration, the raw material is 1M paddy? The mixed grains of paddy and brown rice are hulled in the lower duct 6 and air-sorted in the lower sorting air passage 5, and the selected mixed grains of paddy and brown rice are transferred to a rice lifter 14 for paddy and brown rice via a paddy and brown rice conveyor container 12 provided in the lower gutter. The grains are fried in the distribution box 15 through the curved rice feeding pipe 23.
The mixed grains are supplied to A20. The mixed grains in the flowing grain 120 flow down the sloping clear stream surface by the oscillating motion of the gutter, and flow into the oscillating distribution box 15.
In the chamber 5, the mixed grains oscillate and flow down the clear flow surface 16 of the bottom wall thereof, and are rectified into a flat plate shape by the grain leveling plate 17, and are distributed equally into a plurality of discharge ports 19 and 19. It is divided and supplied to each sorting board 1.1. In each of the sorting plates 1, 1, the mixed grains concentrate the brown rice grain bundles on the upper side of the plate surface and the paddy grain bundles on the opposite side of the plate surface due to the rocking motion of the plate surface, and also concentrate the grain bundles in the middle part. A grain bundle of mixed grains of paddy and brown rice is formed, and each grain bundle is discharged from the side bed and sorted.

As described above, the grain distributing device of the oscillating sorter of the present invention has a structure that rationally combines a plurality of oscillating clear stream surfaces and a grain leveling plate, so that the grain distributing device of the oscillating sorter of the present invention has a structure in which a plurality of oscillating clear stream surfaces and a grain leveling plate are rationally combined. The grain feeding process for mixed grains can be simplified, the structure can be simplified and the manufacturing cost can be reduced, and the connection structure with the hulling device can be simplified, and the grain flow can be smoothed to improve work efficiency. By setting the grain feeding process at a lower level, it is possible to promote the miniaturization of the entire apparatus, and it also has the effect of facilitating efficient sorting action and achieving mass production of high-quality sorted grains. be.
