Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sorting apparatus, and more specifically, a sorting body for sorting grains is provided with a fixed frame through a plurality of suspending tools and the feeding direction of the grains and the feeding direction thereof.
The sorting body is suspended and supported in a tilting direction in a sorting direction intersecting with the
And a sorting device provided with a tilt adjusting mechanism for adjusting a tilt angle in the sorting direction .

[0002]

2. Description of the Related Art In a conventional sorting apparatus, as shown in FIG. 8, four corners of a movable frame 11 serving as a base of the sorting unit are connected to the lower ends of four suspenders 12 and the movable frame 11 is connected. The plurality of sorting bodies 1 are stacked and supported by the above, and the driving unit 19 for circulating movement is connected to the sorting bodies 1.
The tilt angle of the sorting body 1 with respect to the movable frame 11 can be adjusted by operating the electric tilt adjusting mechanism C provided on the movable frame 11.

[0003]

The tilt adjusting mechanism includes a manual type that uses an artificial operating force and an electric type that uses the power of a motor. Since the tilt adjusting mechanism also makes a circular motion integrally with the tilt adjusting mechanism, a problem that is not preferable for any tilt adjusting mechanism occurs as described below.

That is, in the manual tilt adjusting mechanism,
Since the tilt adjusting mechanism cyclically moves together with the oscillator during the sorting, it is difficult to operate the tilt adjusting mechanism during the sorting to adjust the tilt angle. On the other hand, in the electric tilt adjustment mechanism, although it can be operated even during sorting, the electric cord pulled out from the motor must be connected to the fixed frame side, so the middle part of the electric cord floats in the air. It becomes free. Therefore, there is a problem that the existence of the electric cord may be an obstacle in performing maintenance work, or may deteriorate due to a long-term circulating motion to break the wire, which may cause a trouble in maintenance.

Therefore, a supporting frame for supporting the upper side of all of the plurality of hanging devices is mounted on a fixed frame so as to be able to move up and down to form the tilt adjusting mechanism, and the supporting frame is operated by operating the tilt adjusting mechanism. An improved sorting apparatus having a structure in which the hanging tool is raised and lowered to raise and lower and the inclination angle of the sorting body is adjusted based on the raising and lowering is possible. According to such an improved sorting apparatus, since the tilt adjusting mechanism is provided on the fixed frame side, even a manual tilt adjusting mechanism can be operated during sorting to adjust the tilt angle. Even with the electric tilt adjusting mechanism, the electric cord can be reliably fixed to the fixed frame side, and the above-mentioned troubles are not caused.

By the way, even in such an improved sorting apparatus, there are some problems to be solved. That is, since the support frame supports all of the plurality of suspenders, that is,
Since all the load loads on the support frame by the sorting body act, it is necessary to make the structure of the support frame strong, which increases the cost, and it seems that vibration does not occur easily when attaching the support frame to the fixed frame. Therefore, it is necessary to attach it with sufficient strength, and from this point also there is a disadvantage that the cost becomes high.

The present invention has been made in view of the above circumstances, and has a good operability of tilt adjustment during selection, does not cause troubles in the maintenance, and is low in cost, and does not easily cause the vibration. Is intended to provide.

A characteristic structure of a sorting apparatus of the present invention is that the sorting body is one of the plurality of suspending tools.
The hanging tool that suspends and supports the lower side of the sorting direction
It is pivotally supported by a frame, and the selection in the selection body is performed.
The hanging tool that suspends and supports the upper side in the other direction is the fixed frame.
Based on the adjustment to the tilt adjustment mechanism provided on the side
It is supported in a state where it can be raised and lowered .

[0011]

Since the tilt adjusting mechanism is provided on the fixed frame side, the structure does not circulate even during sorting. Therefore, even if the tilt adjustment mechanism is a manual type, the tilt angle can be adjusted by operating it during selection, and even if the tilt adjustment mechanism is an electric type, there is no risk of causing troubles in the maintenance. Moreover, the negative load supported by the tilt adjustment mechanism
In addition to reducing the load, sorting in the sorting body

Are formed. As shown in FIG. 7, the sorting plate 1 is provided with a slope (flow angle: S1) such that the sorting surface 9 is located lower on the lower side X1 in the feeding direction X, and sorting is performed as shown in FIG. The gentle slope side Y1 in the direction Y (the gentle slope side Y1 of the protrusion 10) has a gradient (selection angle: S2) in which the sorting surface 9 is located lower, and only the brown rice of the mixture is placed on the locking portion 10b. Y2 that is locked to the locking portion side in the sorting direction Y
And configured to separate and sort the mixture. The projections 10 are formed by subjecting the selection plate 1 made of a metal plate material to plastic working such as press working.

As shown in FIGS. 1 to 7, the movement regulating mechanism N is tilted with respect to the base frame F while allowing the sorting section 2 to move in the feeding direction X and the sorting direction Y. Four hanging rods 12 and 13 (corresponding to the above-mentioned hanging tool) for hanging
The end of the sorting section 2 on the upper side X2 in the feeding direction is moved in the vertical direction Z
Crank 15 for eccentric rotation about the first axis 14 along the
And a lever 17 for swinging the end portion (lower side portion 1a) of the sorting section 2 on the lower side X1 in the feeding direction around the second shaft 16 along the vertical direction Z. An electric motor 19 as a drive unit is transmission-coupled to the first shaft 14 via a belt 18 as shown in FIG. 2. The electric motor 19 drives the crank 15 to drive the crank 15. The end of the sorting unit 2 on the upper side X2 is rotated around the first shaft 14, and the end of the sorting unit 2 on the lower side X1 (lower side 1a) is rotated by the second shaft 1.
The mixture supplied to the start end side of the selection plate 1 and the position I on the locking portion side Y2 by being swung around 6 has an area G of brown rice and an area where soybean and brown rice are mixed (so-called). Mixed rice area) K and paddy area M are selected.

The collecting section B is provided with a collecting hopper 20 connected to the end of the sorting plate 1. Inside the collecting hopper 20, as shown in FIGS. 4 and 6, brown rice and A first partition plate 21 for separating mixed rice and a second partition plate 22 for separating mixed rice and paddy are provided.

The structure of the suspending and supporting section of the selecting section 2 is constructed as follows. A part of the four suspending rods 12, 13 is a suspending tool 13, specifically, a portion of the movable frame 11 corresponding to the gentle slope side Y1 in the sorting direction Y is pivotally supported at the lower end. The upper end of the hanging rod 13 is pivotally supported by the base frame F. The remaining suspension rod 12, specifically, the suspension rod 12 that pivotally supports at its lower end a portion corresponding to the locking portion side Y2 of the movable frame 11 in the sorting direction Y.
Is an inclination adjuster provided on the base frame F side at the upper end thereof.
It is supported by structure C in a freely movable state based on the adjustment.
I have.

Specifically, as shown in FIG. 1, the tilt adjusting mechanism C has a male screw rod 24 having left and right ends supported on the base frame F side and an operation handle 23 attached to one end thereof.
(The left and right ends of the left and right sides are formed with oppositely oriented male threads) and the left and right pairs are L-shaped when viewed from the front and the intermediate portions 25a are respectively provided with the base frame F. The hanging rod 12 is pivotally supported on one side and at one end 25b.
And a connecting member 25 in which the other end 25c is pivotally supported, and the other end 25c is provided with a top member 26 screwed to the male screw forming portion of the male screw rod 24. Then, when the operation handle 23 is operated to rotate the male screw rod 24, both of the top members 26 in a screwing relationship with the male rod 24 move so as to approach or separate from each other, and the movement causes the connecting member to move. 25 is rotated symmetrically, and the hanging rod 12 is moved up and down based on the rotation, so that the swing adjustment of the sorting plate 1 is performed. The rocking adjustment is performed according to the wetness of the mixed rice at the start of work or the like. That is, mixed rice is 9
Gradient in the sorting direction Y on the sorting surface 9 ( sorting angle: S2 ) so as to be evenly distributed over the entire sorting direction Y.
Is set by the swing adjustment.

The structure of the suspending and supporting section of the selecting section 2 having such a structure is simple as compared with the structure including the supporting frame.

Next, the movement restricting mechanism N will be further described. As shown in FIGS. 3 and 6, the crank 15 has a flange 15a fixed to the upper end of the first shaft 14 provided on the base frame F, and a connecting shaft 15b connected to the flange 15a via a self-aligning bearing 29. Is attached in an eccentric state, and its connecting shaft 15b is inserted into a shaft hole 11a provided in a central portion of a lower stage corresponding to the upper side X2 of the feeding direction X of the movable frame 11, and an upper end portion thereof is attached to the movable frame 11 It is configured to be fixed to the central part of the upper stage. Further, a pulley 14a for hanging the belt 18 is fixed to the lower end of the first shaft 14. With such a configuration, as shown in FIG. 2, the portion of the movable frame 11 corresponding to the upper hand side X2 rotates around the first shaft 14 with almost no movement in the vertical direction Z. The separation and selection of the mixture is performed mainly in a state where the paddy is moved to the gentle slope side Y1 in the selection direction Y due to the difference in specific gravity and the difference in friction coefficient between the brown rice and the paddy. Reference numeral 15c in the figure denotes a balance weight attached to the crank 15.

On the other hand, as shown in FIGS. 6 and 7, the lever 17 has one end pivotally connected to a portion of the movable frame 11 corresponding to the lower side X1 in the feeding direction via a connecting shaft 17a. The other end is pivotally supported by a second shaft 16 fixed to a portion of the base frame F corresponding to the upper side Y2 in the sorting direction. Then, as shown in FIG. 3, the end of the sorting plate 1 on the lower side X1 moves forward to the engaging portion side Y2 of the protrusion 10 and also returns to the gentle slope side Y1 of the protrusion 10. As described above, the second shaft 16 is arranged on the side X2 on the upper side of the connecting shaft for the movable frame 11 in the feeding direction X. With such a configuration, at the end portion on the lower side X1, only the brown rice in the mixture is locked mainly by the locking portion 10b of the protrusion 10 and these are fixed in the sorting direction Y.
Among them, it becomes possible to shift the lock to the engaging portion side Y2 of the selection surface 9 to perform the separation and selection, and at the same time, to quickly send out to the lower side X1 in the feeding direction. According to this structure, the end of the lower hand side X1 is quickly returned toward the backward movement direction when the crank 15 is driven at a constant speed, so that the slow slope 10a of the protrusion 10 is formed. The mixture can be easily passed therethrough, and the function of the protrusion 10 can be sufficiently exerted.

Then, the connection between the crank 15 and the lever 17 is released from the state shown in FIG.
Of the suspension rods 12, 13 on the upper side X2 in the feeding direction in the state where the movable frame 11 is positioned such that the shaft hole 11a provided on the lower surface thereof and the second shaft 16 coincide with each other. The hanging rods 12 and 13 of the book are in a posture substantially along the vertical direction Z, and the two hanging rods 12 and 13 located on the lower side X1 in the feeding direction are inclined so as to lie down toward the lower side X1. Thus, the hanging rods 12 and 13 are arranged. According to this arrangement, as shown in FIG. 2, when the crank 15 and the lever 17 are connected to the sorting body 2, the locus 12b of the lower ends of the hanging rods 12 and 13 located on the lower side X1 thereof. Has a shape that substantially descends toward the lower side X1 in the feeding direction, and as shown in FIG. 3, a movement locus 12a of the lower ends of the hanging rods 12 and 13 located on the upper side X2 falls within a substantially horizontal plane. It becomes an exercise.
Therefore, as the sorting plate 1 moves to the lower side X1 in the feeding direction, the end of the upper side X2 in the feeding direction X moves downward while the flow angle S1 increases, while the feeding direction X increases. The end of the upper hand side X2 hardly moves up and down.

That is, according to this structure, the lower side X2
Since the moving speed of the mixture at the end portion of (1) to the lower side X1 in the feeding direction becomes large, the mixture spreads thinly and is deposited, and the function of the protrusion 10 can be sufficiently exerted. On the other hand, at the end of the above-mentioned side X2, since the moving speed of the mixture toward the lower side X1 in the feeding direction becomes smaller, the mixture is agitated in the deposited state, and different from the end of the above-mentioned side X2. It becomes possible to share the selection by the action. In addition, the hanging rod 1 on the lower side
As shown by the phantom lines in FIG. 2, 2 and 13 are the sorting bodies 2
In the state in which is located on the lowermost side in the feeding direction X, since it is inclined to be at least orthogonal to the selection surface 9, the movement locus of the lower side portion 1a is lower than the flow angle S1. As a result, the above-mentioned effects are more remarkably exhibited.

The specific construction of each part necessary for carrying out the present invention can be variously modified from the above-mentioned embodiment.

The present invention can also be applied to other sorters different from the above-described embodiment (brown rice sorter), such as a grain sorter in a rice polishing process.

It should be noted that reference numerals are added to the claims for convenience of comparison with the drawings, but the present invention is not limited to the structures of the accompanying drawings by the entry.
