Description

[Detailed description of the invention] The present invention relates to an improvement of a machine frame support device for a grain sorter.

In general, grains such as pigeon wheat and beans have a rounded shape and a flat plate.
Although the grains are unstable and easily roll, damaged grains that have been damaged by insects, diseases, fertility problems, or mechanical damage usually have a different shape or elasticity than whole grains. be.

The present invention utilizes the differences in shape, elasticity, and specific gravity between intact grains and damaged grains to efficiently sort the grains.The entire apparatus is constructed by supporting a sorting machine frame consisting of a perforated wall sorting plate with a corrugated surface by a simple support structure. An object of the present invention is to develop and provide a convenient device that can reduce the weight of the sorting plate and easily adjust the inclination angle of the sorting plate.

The present invention will be explained with reference to embodiment figures. In Fig. 3, reference numeral (1) is a porous wall sorting plate formed on a wavy surface (2). ) A complete grain discharge port (4) provided in the floor section of the sorting plate (1), which separates the mixed grains supplied to the sorting plate (1) from the separating plate (1) into the front and rear while flowing in the lateral direction; Mixed grain outlet (5), damaged grain outlet (6)
It is formed to discharge the sorted grains respectively.

Figures 1 and 2 show a grain sorting machine equipped with the above-mentioned porous wall sorting plate, in which a porous wall sorting plate (1) with a supply port (3) on the negative side is installed in a gently inclined manner. A ventilation chamber (7) is provided in the upper part of the sorting plate (1), and a ventilation chamber (8) is provided in the lower part thereof to integrally form a sorting machine frame (9). )
A swing mechanism (10) and a wind turbine box (11) are arranged in relation to each other at the bottom of the screen, and the swing mechanism (10) is connected to an upper support point (+2) (13) provided on the lower wall surface of the sorter frame (9). )(12)
(13) and the lower fulcrum (1
5) (16) (15) (16) are connected by elastic support rods (17) (18) (17) (18) respectively, and a vibration device consisting of a 77V force point of the machine frame (9) and an eccentric cam is created. (19) crank (2+)) to the rod (21
). The wind turbine box (11) is stably fixed by connecting its lower part to the horizontal underframe (22) with a fastener (z3), and is attached to the cylindrical body side of the folded wind turbine box (11). A rotating shaft (24) is installed horizontally, and a supporting rod (25) (25) with a supporting shaft is provided on the other side of the cylindrical body so as to protrude from the rotating shaft (24). (IJ transverse arm rod (

is attached to the shaft. In addition, (36) is a wind tunnel part which communicates with the ventilation chamber (8) for θξL car Hakogawa).

With the above-mentioned configuration, when raw beans are put into the supply section of the elevator (29) and the device is started, the grain tank (31
) to the lower perforated wall sorting plate (1). The porous wall sorting plate (1) is vibrated by the swinging mechanism (10) so that the wavy surface (2) of the sorting plate vibrates back and forth during excavation.
In addition, on the porous wall surface, the wind generated in the wind turbine box (11) blows toward the ventilation chamber (7) via the ventilation chamber (8), so that the beans supplied to the sorting plate (1) are As the grains flow down on the sloping wavy surface (2), they form a flat grain layer, and incomplete grains with low specific gravity (damaged grains, half-split grains) are broken down by the blast action from the porous wall surface. As they float to the top of the grain layer, complete grains with high specific gravity gather at the bottom of the grain layer,
Due to the oscillating action of the mountain-shaped veins mentioned above, the complete grains at the bottom of the grain layer are pushed up forward to the higher side and drift laterally to form a complete grain flux (P) (see Figure 3). The incomplete grains floating on the upper surface of the grain J are shifted laterally while sliding backward and lower on the upper surface of the whole grain, forming a damaged grain flux (R), and each flux (P) ( A mixed grain flux (Q) of complete grains and incomplete grains is formed between R), and each flows into the bed section of the sorting plate, where they are separated and discharged. The particle shape and moisture content of beans and other grains vary depending on the grain type, production area, growth conditions, etc., and the flow state of the grains on the sorting plate surface changes.5- The sorting machine It is safe to adjust the elevation angle of the porous wall sorting plate (+) in the frame (9) as appropriate. In the present invention,
- of the horizontal arm rod (14) provided on the swing mechanism (10)
The side end is pivotally connected to the rotation shaft (2/I), and the other side end is connected to the support rod (25) via the angle adjustment device (26). By rotating the rotary handle (85) provided in the forward or reverse direction, the adjustment screw shaft (3) is rotated through the rotation mechanism (32).
3) rotates and moves up and down, and as the screw shaft (83) rotates, one end of the horizontal arm rod (one side end of the group) moves up and down, and the porous wall in the sorter frame (9) moves up and down. The elevation angle of the sorting plate (1) can be changed and adjusted to any angle.

As described above, the grain sorter frame support device of the present invention stably functions as a windmill with a support rod equipped with a rotating shaft and an angle adjustment device provided on both sides of the cylindrical body. Since the entire sorter frame is supported through the swinging mechanism, the windmill box is built into the box-shaped underframe of the conventional device, and a sorter frame equipped with a swinging mechanism is mounted on the top of the underframe. Compared to the previous model, the #7 unit and structure are simpler and the manufacturing cost is lower, and the weight of the whole device is significantly reduced, making it easier to transport, install, etc. The adjustment mechanism for the inclination angle of the sorting plate has been simplified to η11, and grain sorting of multiple varieties can be done instantly.7.?
This has the effect of ensuring that 14 grains of carefully selected high-quality grain can be produced reliably, smoothly, and quickly.
