Description

The present invention relates to, for example, a grain sorting machine that sorts grains, granules, etc., and sorts them according to the size of the particle size, in particular, a single-row multistage grain sorter in which sorting cylinders are arranged in a single-row multistage and a single-row multistage The present invention relates to a method of removing an inclined guide plate and upper and lower sorting cylinders from a main body frame of a grain sorter .

  2. Description of the Related Art Conventionally, for example in cereals, a grain sorter that sorts grains such as rice grains into sized grains and waste grains such as immature grains is known. For example, the sorting machine proposed in Patent Document 1 has a mesh-like sorting cylinder rotatably arranged, and the sorting cylinder is installed at a necessary angle so that the granule supply side is high and the discharge side is low. Then, the particles to be sorted are supplied to the inside of the sorting cylinder from the supply side of the sorting cylinder, and by the rotation of the sorting cylinder, small waste particles having passed through the mesh of the sorting cylinder are placed in the lower part in the longitudinal direction of the sorting cylinder. The sized particles that are discharged along with the shutters of the hopper-shaped waste particles arranged along the screen and do not pass through the mesh of the sorting cylinder are caused to flow down to the discharge side due to the inclination of the sorting cylinder and are discharged.

  Also known is a multi-row multi-stage grain sorter in which a single sorting cylinder shown in Patent Document 1 is arranged in multiple rows in the horizontal direction and in multiple rows in the vertical direction. For example, in Patent Literature 2, two rows in the horizontal direction are known. , Two stages of sorting cylinders are arranged in the vertical direction, and in Patent Document 3, two rows are arranged in the horizontal direction and three stages of sorting cylinders are arranged in the vertical direction.

  Although the sorting machine in which a plurality of sorting cylinders as shown in Patent Documents 2 and 3 are arranged in multiple rows and multiple stages has a high sorting processing capacity, the sorting cylinders are arranged side by side in the horizontal direction. This type of sorter is disadvantageous in terms of space and space saving, and this type of sorter is suitable for the main body frame when it is replaced with a mesh sorter that matches the size of the grain to be sorted. Each sorting cylinder is detachably attached to the main body frame so that each sorting cylinder can be removed. However, the multi-row multistage sorter shown in Patent Documents 2 and 3 is structurally arranged from one side. Can only be removed. That is, the two-row, two-stage sorter shown in Patent Document 2 employs a structure in which the sorting cylinders arranged on the left and right are extracted from the short direction perpendicular to the axial direction, Only the right side of the left and right sorting cylinders can be removed. On the other hand, the two-row / three-stage sorter shown in Patent Document 3 can extract each sorting cylinder only in the axial direction (longitudinal direction). Therefore, in order to remove the sorting cylinder from the axial direction, at least from the sorting machine It is necessary to secure a long space, and the installation position of the sorter is restricted by the direction in which the sorting cylinder is pulled out. When the sorting cylinder is pulled out from the main body, the sorting cylinder interferes with the main body and damages the mesh. There is also a fear.

  Furthermore, in the multi-row multi-stage sorter shown in Patent Documents 2 and 3, small crushed particles classified by sieving with a sorting cylinder arranged on the upper stage side pass through the mesh of the lower sorting cylinder to adjust the size. There is a risk of mixing, which is an important issue to be solved in order to ensure sorting accuracy.

  Therefore, the present invention has been made paying attention to the above problems, and in a single-row multi-stage type grain sorter in which a plurality of sorting cylinders are arranged in upper and lower stages, when the sorting cylinders are replaced, the sorting cylinders are shorter than the main body frame. It is possible to extract from both sides of the direction, increasing the degree of freedom of layout when installing a single row multistage type grain sorter, and the waste grains that have passed through the mesh of the upper stage side sorting cylinder are lower side sorting cylinders An object of the present invention is to provide a single-row, multi-stage type grain sorter that can be reliably discharged without passing through the mesh and mixing with the sized particles.

A single-row multi-stage grain sorter according to claim 1 of the present invention is a sorting cylinder that is rotated by tilting a required angle so that the trunk portion is mesh-shaped, the supply side is high, and the discharge side is low. A hopper for collecting waste particles that transports particles below the reference value that passed through the mesh of the sorting cylinder, and a sized export that delivers the sized particles that meet the criteria discharged from the sorting cylinder without passing through the mesh of the sorting cylinder and use the chute, and a main frame for fixing the respective components in a single-row multi-stage particle separator disposed in a vertical multistage said sorting cylinder to the body frame in a row, each sorting cylinder disposed in the top and bottom An inclined guide plate is provided for guiding the waste particles from the upper sorting cylinder to the waste particle collecting hopper, and the inclined guide plate and the upper and lower sorting cylinders are inclined with respect to the main body frame. The left side, which is the higher side of the guide plate, and the lower side In order provided from both sides of the right detachably is, the body frame is provided with a removable lateral side panels, supporting the inclined guide plate in an axial direction end side of the screened cylinder located in said main body frame A pair of supporting rails are provided along the short direction of the main body frame, and the inclined guide plate is slidably attached to the support rail so as to be detachably attached. The cylinder is characterized in that the main body frame can be removed from both sides in the short direction perpendicular to the axial direction of the sorting cylinders with respect to the main body frame .

The single-row multi-stage grain sorter according to claim 2 of the present invention is such that, on the higher side of the inclined guide plate, one end edge of the inclined guide plate is bent into an L shape and locked to the upper end edge of the support rail. The stopper piece to be formed is formed .

The present invention provides a method for removing the inclined guide plate and the upper and lower sorting cylinders from the main body frame with respect to a single row multi-stage grain sorter, wherein the inclined guide plate and the upper and lower sorting cylinders are removed from the left side of the main body frame. When removing, remove the left side panel from the main body frame to open the left side of the main body frame, slide the inclined guide plate to the higher side along the support rail, remove the inclined guide plate, After removing the inclined guide plate, remove from the main body frame in the order of the upper stage selection cylinder, the lower stage side selection cylinder, when removing the inclined guide plate and the upper and lower selection cylinder from the right side of the main body frame, The right side panel is removed from the main body frame to open the right side of the main body frame. The step-side sorting cylinder is extracted from the main body frame, the upper part of the inclined guide plate is opened, the locking of the stopper piece of the inclined guide plate and the support rail is released, and the inclined guide plate is moved to the support rail. After that, the lower sorting cylinder is removed from the main body frame .

  The single-row multistage grain sorter of the present invention arranges upper and lower sorting cylinders in parallel with each other and arranges them in a single-row multistage. can do. In addition, by arranging the single row of sorting cylinders vertically, the floor area of the multistage grain sorting machine is the same as that of the grain sorting machine equipped with a single sorting cylinder. Waste particles that have passed through the mesh of the side sorting cylinder can be reliably discharged to the waste particle recovery hopper along the inclination of the inclined guide plate.

  Further, since the inclined guide plate is inclined so that the tip side is directed downward in the rotation direction of the upper-stage sorting cylinder at a position close to the sorting cylinder located on the upper-stage side of the inclined guide plate, Even if the inclination angle of the plate is set to be relatively small, the debris that has passed through the mesh of the sorting cylinder is effectively moved to the lower side of the inclined guide plate along the inclination of the inclined guide plate by the centrifugal force caused by the rotation of the sorting cylinder. Flowing into. Accordingly, the waste particles can be reliably discharged to the waste particle collecting hopper without remaining on the inclined guide plate. Further, by setting the inclination angle of the inclined guide plate to be relatively small, the layout between the upper and lower sorting cylinders can be narrowed, and the overall height of the single-row multi-stage grain sorter can be suppressed and the size can be reduced.

  In addition, since the tilt guide plate and the upper and lower sorting cylinders can be removed from either the left or right side in the short direction with respect to the main body frame, an extra space for pulling out the tilt guide plate or the upper and lower sorting cylinders. There is no need to secure Furthermore, for example, even if two single-row multi-stage grain sorters are juxtaposed or a single single-row multi-stage grain sorter is placed close to the wall, the sorting cylinder and the inclined guide plate can be removed. It is possible to select the installation position of the single row multistage grain sorter relatively freely.

  Embodiments of the present invention will be described below with reference to the accompanying drawings. In addition, in a present Example, the case where a grain, such as rice grain, is sorted as a selection target according to the particle size into a grain size such as sized grain and immature grain, will be described as an example.

  A single-row multi-stage grain sorter 1 according to the present invention includes a sorting unit 2 for sorting grains, a supply unit 3 for supplying granules to the sorting unit 2, and a waste for discharging waste grains that have passed through the mesh of the sorting unit 2. It consists of a particle collection hopper 4, a sizing / unloading chute 5 for unloading the sized particles sorted by the sorting unit 2, and a main body frame 6 for fixing these components. In this embodiment, the single-row multi-stage grain sorter 1 shown in FIG. 1 is the front of the single-row multi-stage grain sorter 1, the right side is the right side of the single-row multi-stage grain sorter 1, and the left side is the single side. It is defined as the left side of the row multi-stage grain sorter 1. The single-row multi-stage grain sorter means a grain sorter having a structure in which single-row sorters are arranged one above the other.

  Next, a specific structure of each component will be described with reference to FIGS. The sorting unit 2 includes cylindrical sorting cylinders 10 and 11 arranged in multiple stages in the upper and lower directions, which are composed of a mesh frame made of a required mesh as a whole, and a drive motor 7 that rotates the sorting cylinders 10 and 11. It is installed in the main body frame 6 so as to be inclined at a required angle so that the supply side of the granules is high and the discharge side of the granules is the bottom. In addition, each of the sorting cylinders 10 and 11 has a mesh size (mesh width) determined according to the quality, grade or application of the rice grains to be sorted, and scraps below the standard that have passed through the mesh are scraps. It flows down to the collection hopper 4 and is carried out of the machine by the carry-out conveyor 8 assembled to the lower part of the waste particle collection hopper 4. On the other hand, the sized particles conveyed to the lower discharge side without passing through the meshes of the sorting cylinders 10 and 11 fall from the sorting cylinders 10 and 11 to the sized particle discharge chute 5 and are carried out of the machine.

  The supply unit 3 is located on the supply end side 10a, 11a (higher side) of the sorting cylinders 10 and 11 and is assembled to the main body frame 6. The particle supply hopper 12 and the input hopper 12 The supply pipes 13 and 13 are divided into two forks. One end of the supply pipe 13 faces the supply side opening of the sorting cylinder 10 positioned on the upper side, and the other end of the supply pipe 13 extends to the supply side opening of the lower sorting cylinder 11. 14 and a hopper 17 that receives the particles are connected, and the outlet side of the hopper 17 faces the supply side opening of the sorting cylinder 11. With the above structure, the granules supplied to the charging hopper 12 are supplied from the supply pipes 13 and 13 into the upper and lower sorting cylinders 10 and 11.

  The main body frame 6 includes a front panel 6A, a rear panel 6B, and left and right side panels 6C and 6D. The left and right side panels 6C and 6D are divided into two vertically corresponding to the upper and lower sorting cylinders 10 and 11, respectively. Configured. Further, in the main body frame 6, a sized particle carrying-out path 19 a discharged from each sorting cylinder 10, 11 is defined by being positioned on the discharge end side 10 b, 11 b (low side) side of each sorting cylinder 10, 11. A partition plate 19 is formed. Further, in the main body frame 6, an inclined guide plate 20 that is located between the respective sorting cylinders 10 and 11 and guides the waste particles passing through the mesh of the upper-stage sorting cylinder 10, and the inclined guide plate 20 A vertical guide plate 21 is provided for guiding the waste particles flowing down to the waste particle recovery hopper 4.

  A pair of support rails 22 are attached to the inner side of the partition plate 19 and the rear panel 6B of the main body frame 6 as a support member for the inclined guide plate 20, and from the higher side of the inclined guide plate 20. By sliding both side edges of the inclined guide plate 20 along the support rail 22, a stopper piece 20A (shown in FIGS. 4 and 5) bent into an L shape from one end edge of the inclined guide plate 20 is supported by the support rail. The inclined guide plate 20 is positioned and held by being engaged with the upper end edge of 22. The stopper piece 20 </ b> A is formed on the higher side of the inclined guide plate 20, and the engagement state between the stopper piece 20 </ b> A and the support rail 22 is maintained by the weight of the inclined guide plate 20. The vertical guide plate 21 is fixed so as to face the lower side edge of the inclined guide plate 20 and to be parallel to the right side panel 6D of the main body frame 6. Thereby, the waste particles passing through the mesh of the upper-stage sorting cylinder 10 flow down along the inclined guide plate 20, and are guided to the gap between the vertical guide plate 21 and the right side panel 6D, and the waste particles are collected through the gap. The hopper 4 is discharged. It should be noted that, in the proximity of the inclined guide plate 20 and the upper-stage sorting cylinder 10 located on the upper stage side, the inclined guide plate 20 is arranged such that the tip side faces downward in the rotation direction of the upper-stage sorting cylinder 10. It is attached to the guide rail 22 with an inclination. The left and right side panels 6C and 6D are formed with inspection window portions 31 for confirming clogging of the respective sorting cylinders 10 and 11. The vertical guides correspond to the inspection window portions 31. A transparent plate 24 is attached to a notch 23 formed in the plate 21. In addition, the code | symbol 30 in a figure is the scraper attached to 6 C of left side panels so that each selection cylinder 10 and 11 may be touched.

  The upper and lower sorting cylinders 10 and 11 are detachably attached to the main body frame 6, and the mounting structure of the sorting cylinders 10 and 11 will be described. A shaft 25 for rotatably supporting the sorting cylinders 10 and 11 on the front panel 6A of the main body frame 6 is fixed, and the drive motor 7 is fixed to the rear panel 6B of the main body frame 6, and on both sides of the sorting cylinders 10 and 11. A bearing 26 that supports the shaft 25 and a projecting shaft 27 that fits with a rotating shaft (not shown) of the drive motor 7 are attached. The shaft 25 is screwed from the outer surface side of the front panel 6A, and can be removed from the front panel 6A by loosening the screw. Thus, when the selection cylinders 10 and 11 are extracted from the main body frame 6, first, the shaft 25 is extracted from the front panel 6A so that one end of the selection cylinders 10 and 11 is a free end, and then the projecting shaft of the selection cylinders 10 and 11 is removed. By extracting 27 from the rotating shaft (not shown) of the drive motor 7, each sorting cylinder 10, 11 can be extracted from either side of the left and right side surfaces of the main body frame 6.

  Next, a method for removing the inclined guide plate 20 and the upper and lower sorting cylinders 10 and 11 will be described with reference to FIGS. 6 shows the order in which the inclined guide plate 20 and the upper and lower sorting cylinders 10 and 11 are removed. To remove the inclined guide plate 20 from the left side of the main body frame 6, as shown in FIG. The left and right side panels 6C and 6C are removed to open the left side of the main body frame 6. The left side surface of the main body frame 6 is positioned on the higher side of the inclined guide plate 20 where the stopper piece 20 </ b> A of the inclined guide plate 20 is locked to the support rail 22, so that the inclined guide plate 20 is simply moved along the support rail 22. The inclined guide plate 20 can be removed simply by sliding it to the higher position. When the inclined guide plate 20 is attached to the support rail 22, the inclined guide plate 20 is slid along the support rail 22 to the lower side in the reverse procedure. And after removing the inclination guide plate 20, it removes in order of the upper stage side selection cylinder 10 and the lower stage side selection cylinder 11 from the main body frame 6 (refer the order of FIG. 6).

  On the other hand, when removing the inclined guide plate 20 from the right side of the main body frame 6, the upper and lower right side panels 6D and 6D are removed from the main body frame 6 to open the right side of the main body frame 6, as shown in FIG. The right side surface of the main body frame 6 is positioned on the lower side of the inclined guide plate 20, and the inclined guide plate 20 is disposed between the respective selection tubes 10 and 11 as close as possible to the respective selection tubes 10 and 11. Therefore, in order to release the engagement between the stopper piece 20A of the inclined guide plate 20 and the support rail 22, it is necessary to lift the inclined guide plate 20 beyond the length of the stopper piece 20A. Therefore, first, the upper sorting cylinder 10 located at the upper part of the inclined guide plate 20 is extracted from the main body frame 6 to open the upper part of the inclined guide plate 20. Thereby, as shown by the arrow in FIG. 5, the inclined guide plate 20 can be lifted and the inclined guide plate 20 can be detached from the support rail 22. After removing the inclined guide plate 20 in this way, the lower-stage sorting cylinder 11 is removed from the main body frame 6 (see the order in FIG. 6).

  Next, the operation of the present invention will be described. By supplying the granules to the charging hopper 12 of the supply unit 3, the particles in the charging hopper 12 are supplied to the bifurcated supply pipes 13, 13. Granules are supplied from the other supply pipe 13 through the flexible pipe 14 and the hopper 17 into the lower sorting cylinder 11. And the granule supplied into each sorting cylinder 10 and 11 flows from the supply side (higher side) to the discharge side (lower side) by the inclination of each sorting cylinder 10 and 11 that is rotationally driven by the drive motor 7, On the way, scrap particles below the standard pass from the meshes of the sorting cylinders 10 and 11. At this time, the waste particles flowing down from the upper sorting cylinder 10 fall on the inclined guide plate 20 interposed between the sorting cylinders 10 and 11, and then the vertical guide plate 21 and the right side surface are inclined by the inclination of the inclined guide plate 20. It is discharged to the waste particle collecting hopper 4 through the gap with the panel 6D. Further, the sized particles conveyed to the lower discharge side without passing through the meshes of the sorting cylinders 10 and 11 are unloaded from the unloading path 19a separated from the terminal portion of the sorting cylinders 10 and 11 by the partition plate 19. It falls on the work chute 5 and is carried out of the machine.

  As described above, in the present embodiment, the upper and lower sorting cylinders 10 and 11 are arranged in parallel to each other, and the sorting processing capacity is increased by sorting the granules by the sorting cylinders 10 and 11, thereby increasing the amount of sorting. Granules can be sorted. Further, by arranging the sorting cylinders 10 and 11 vertically, the floor area of the single-row multistage grain sorting machine 1 is the same as that of the grain sorting machine having a single sorting cylinder, which can contribute to space saving. At the same time, the waste particles that have passed through the upper sorting cylinder 10 are discharged along the inclination of the inclined guide plate 20 to the waste particle collecting hopper 4 through the space between the vertical guide plate 21 and the right side panel 6D. Therefore, even when the upper and lower sorting cylinders 10 and 11 are arranged close to each other, the waste particles that have passed through the mesh of the upper sorting cylinder 10 pass through the mesh of the lower sorting cylinder 11 and are not mixed into the sizing. The waste particles can be reliably discharged to the hopper 4 for particle recovery. Further, the inclined guide plate 20 is inclined to the guide rail 22 so that the tip side is directed downward in the rotational direction of the upper-stage sorting cylinder 10 at a position close to the upper-stage sorting cylinder 10 located on the upper stage side. Since it is attached, the waste particles that have passed from the sorting cylinders 10 and 11 are effectively moved to the lower side of the inclined guide plate 20 along the inclination of the inclined guide plate 20 due to the centrifugal force generated by the rotation of the sorting tubes 10 and 11. Flowing into. Thereby, the waste particles are reliably discharged to the waste particle collecting hopper 4 without remaining on the inclined guide plate 20, and the inclination angle of the inclined guide plate 20 is set to be relatively small (in this embodiment). About 25 °). As a result, a layout in which the distance between the upper and lower sorting cylinders 10 and 11 is made as narrow as possible is possible, and the overall height of the single-row multi-stage grain sorter 1 can be suppressed and the size can be reduced.

  Further, the inclined guide plate 20 and the upper and lower sorting cylinders 10 and 11 can be removed from either the left or right direction of the main body frame 6, and the direction in which the inclined guide plate 20 and the upper and lower sorting cylinders 10 and 11 are taken out. Is a short direction of the main body frame 6 perpendicular to the axial direction of the sorting cylinders 10 and 11, and therefore it is necessary to secure an extra space for pulling out the inclined guide plate 20 or the upper and lower sorting cylinders 10 and 11. Absent. Therefore, the single-row multistage grain sorter 1 can be laid out relatively freely. Further, when the sorting cylinders 10 and 11 are pulled out, the sorting cylinders 10 and 11 can be pulled out from the right side surface or the left side surface of the opened main body frame 6, and damage to the sorting cylinders 10 and 11 due to interference with the main body frame 6 can be suppressed. . Furthermore, since each of the sorting cylinders 10 and 11 and the inclined guide plate 20 can be extracted from either the left or right side of the main body frame 6, as shown in FIG. When the machines 1 and 1 are installed side by side, the single-row multistage grain sorter 1 on the left side in the figure can extract the sorting cylinders 10 and 11 and the inclined guide plate 20 from the left side surface, and the single-row multistage type on the right side in the figure. The grain sorter 1 can extract the sorting cylinders 10 and 11 and the inclined guide plate 20 from the right side surface. Further, when the single-row multi-stage grain sorter 1 is arranged adjacent to the wall K, the sorting cylinders 10 and 11 and the inclined guide are provided from the side opposite to the wall K as shown in FIGS. The plate 20 can be extracted, and the degree of freedom of the layout of the single-row multistage grain sorter 1 can be increased.

  Further, the left and right side panels 6C and 6D are provided with inspection window portions 31 for checking the clogging of the respective sorting cylinders 10 and 11, and corresponding to the inspection window portions 31 of the lower right side panel 6D. Since the guide plate 21 is provided with the notch 23 and the transparent plate 24, the sorting tube 11 is not obstructed by the vertical guide plate 21, and can be seen well from the outer surface side of the single-row multistage grain sorter 1. It is also easy to maintain.

  As mentioned above, although each Example of this invention was explained in full detail, this invention is not limited to each said Example, A various deformation | transformation implementation is possible within the range of the summary of this invention. For example, the selection target is applicable not only to grains such as rice grains but also to various grains. Further, in the above-described embodiment, an example in which the upper and lower two-stage sorting cylinders 10 and 11 are provided is shown. However, three or more sorting cylinders may be provided. The mounting structure of 20 or the support structure of the inclined guide plate 20 is not limited to the structure of the above embodiment, and may be selected as appropriate.
