Description of the Related Art Conventionally harvested rice grains are mixed with grains with branch spikes, causing clogging in a conveying path of a dryer, a rice huller, or the like, which is to be performed in a later process, or the generation of the rice grains. When seeded as seed rice, there is a problem that the seeding is not uniform and uneven. In order to solve this problem,
An apparatus for removing a branch vein as described in Japanese Patent Application No. 14117 has been published. [0003] However, the one disclosed in this publication has a rotating cylinder that erects a spiral by winding a spiral in a cylindrical body having a wavy peripheral surface. Then, while being lifted up by the spiral between the inner peripheral surface of the cylindrical body and the rotating body, the waves collide with the waves and the action of removing branch branches is performed. Unnecessarily, the treated rice grains are not taken out to the outside and the upper part of the cylindrical body is discharged to the side, so that the removal of the branch stalks is unnecessarily repeated in the rice grains, and damaged grains are generated. The present invention has disadvantages such as a lower processing ability of branch shoots, and the present invention solves such a drawback and greatly increases the processing performance of branch shoot removal while causing damage to rice grain. The present invention has been made for the purpose of providing something that does not exist. [0004] In order to achieve the above object, the present invention provides a vertical cylindrical screw formed with a large number of cutouts for cutting a branch, the size of which is such that rice grains pass through the peripheral surface. A rotating drum is provided in the inside of the spiral so as to wrap a spiral to lift the rice grains, and the rice grains flow down between the outer peripheral edge of the spiral and the inner peripheral surface of the cylindrical screen. As well as possible intervals,
An outlet through which the cylindrical screen is surrounded by an outer cylinder and which passes through the above-mentioned branch incision hole and takes out the object which falls between the outer peripheral surface of the cylindrical screen and the outer cylinder; A discharge port for discharging a substance descending between the inner peripheral surface of the cylindrical screen and the rotary drum is provided separately. [0005] With this configuration, when the rice grain mixed with grains with branch stalks is supplied into the cylindrical screen, it is subjected to a push-up action by the spiral wound around the rotating rotating drum and is stirred while being stirred. The rice grain flows down between the outer peripheral edge and the inner peripheral surface of the cylindrical screen, while the rice grain is discharged from the branch incision hole, and the grain with branch incision is cut off from the rice grain by the branch incision hole. Those that are ejected from the branch incision hole due to the excision action of falling, fall between the outer peripheral surface of the cylindrical screen and the outer cylinder, are taken out from the outlet, and those not ejected from the branch incision hole are cylindrical screens. The process of falling down between the inner peripheral surface of the fin and the rotating drum and being discharged from the discharge port, the single grain from the beginning and the single grain formed by the cutting action of the branch vein flow down And the processing capacity goes up. It is no longer subjected to the action of removing the branch incision and does not produce damaged grains. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings, in which (1) is a vertical cylindrical screen, which is a branch incision hole having a size such that rice grains pass through the peripheral surface. A large number of (2) are formed, and the outer periphery thereof is surrounded by an outer cylinder (5) at an interval (L). A rotary drum (3) on which a spiral (4) is wound is attached to a vertical drive shaft (8) in the cylindrical screen (1) to give a lifting effect to the rice grains. ), And the portion of the spiral (4) wound around from the upper part to the middle part of the rotating drum (3) has an outer peripheral edge of the spiral (4) and a cylindrical screen (1). ) Is formed at a certain interval (M) where the rice grains can flow down, and several projections (9) are arranged to form a treatment zone (A). The spiral (4) at the lower limb of the rotating drum (3) is an intermittent spiral provided with a notch (4a), and the gap (N) is brought close to the inner peripheral surface of the cylindrical screen (1). Are narrowed to form a processing zone (B). The upper portion of the cylindrical screen (1) is opened to form a supply port (10) and further expands in a funnel shape, and the lower end has a discharge port (7) having a discharge port (7). A vane (12) is provided around the rotary drum (3) in the discharge drum (11), so that the inner peripheral surface of the cylindrical screen (1) and the rotary drum (3) are connected. What descends from the space is splashed out of the discharge port (7), and a blade (13) that rotates integrally with the rotary drum (3) is attached to the upper side of the blade (12). An object falling in the space (L) between the outer peripheral surface of the pin (1) and the outer cylinder (5) is made to jump out of the outlet (6). A vertical air intake port (14) is formed around the lower part of the outer cylinder (5), and a drive shaft (8) is provided above.
A suction / exhaust blade (15), which rotates integrally with the suction port, is attached to the processing chamber for sucking outside air from an outside air suction port (14).
(A) and (B) are sucked and discharged from the dust outlet (16). Note that (1
7) is a pulley for driving the drive shaft (8). The branch incision hole (2) formed on the peripheral surface of the cylindrical screen (1) has a punch hole shape as shown in FIG. 6 in the processing zone (A). The processing zone (B) has a cross shape as shown in FIG. 7 or a V-shape as shown in FIG. 8 and has a different mesh from the processing zone (A). is there. The processing zone (B) may have a shape as shown in FIG. [0010] Therefore, when the rotary drum (3) on which the spiral (4) is wound by the pulley (17) is rotating in the direction (a), the cylindrical screw is fed from the supply port (10).
When the rice grain mixed with grains with branch stalks is supplied into the corn (1), the rice grain is subjected to a push-up action by the spiral (4) and is agitated while being stirred in the treatment zone (A). It flows down between the outer peripheral edge of (4) and the inner peripheral surface of the cylindrical screen (1). In the meantime, a single grain is discharged from the branch incision hole (2) from the beginning, and it has a branch incision. By the action of the branch incision hole (2) and the projection (9), the branch incision is cut from the rice grain and discharged through the branch incision hole (2), and the branch in the treated zone (B). Those which are not discharged from the resection hole (2) descend to the processing zone (B) and are processed by the intermittent spirer provided with the cutout (4a) in the spiral (4) to be treated by the branch incision. It will be discharged from the branch incision hole (2). In the treatment zones (A) and (B), a single grain from the beginning discharged from the branch incision hole (2) and a single grain by the branch incision action are formed. An untreated material that falls between the outer peripheral surface of the cylindrical screen (1) and the outer cylinder (5), is taken out from the outlet (6) by the blade (13), and is not discharged from the branch incision hole (2). Moves down between the inner peripheral surface of the cylindrical screen (1) and the rotating drum (3) to move the blades (1).
The spring is ejected by 2) and is discharged from the discharge port (7). The one discharged from the resection hole (2) and the one not discharged from the branch incision hole (2) of the cylindrical screen (1) are taken out (6). )
And the discharge port (7). In this way, the branching and severing action is performed in the processing zones (A) and (B). Dust generated by the action is sucked and discharged by the suction / discharge blade (15) to open the outside air inlet ( 14) Intakes outside air and sucks and discharges air floating between the outer peripheral surface of the cylindrical screen (1) and the outer cylinder (5), and rotates with the inner peripheral surface of the cylindrical screen (1). Dust floating between the trunks (3) is sucked out through the branch incision hole (2) and discharged together with the dust outlet (16). According to the present invention, as described above, the apparatus for removing a branch infarction according to the present invention is a vertical cylinder having a large number of branch incision holes (2) formed on the peripheral surface thereof so as to allow the passage of rice grains. In the screen (1), a rotating drum (3) for winding up a spike (4) to give a lifting effect to the rice grains is erected, and the spirer (4) is erected.
The space between the outer peripheral edge of the shell and the inner peripheral surface of the cylindrical screen (1) is set so that the rice grains can flow down (M).
The shell (1) is surrounded by an outer cylinder (5), and the object that passes through the branch incision hole (2) and falls between the outer peripheral surface of the cylindrical screen (1) and the outer cylinder (5) is taken out. An outlet (6),
Discharge ports (7) are provided separately for discharging those that pass down between the inner peripheral surface of the cylindrical screen (1) and the rotating body (3) without passing through the branch incision hole (2). Therefore, the paddy grains mixed with grains with branch spikes supplied into the cylindrical screen (1) are mixed by a spiral (4) wound around a rotating rotary drum (3). The outer peripheral edge of the spiral (4) and the cylindrical screen are stirred while being subjected to the push-up action.
In the meantime, the rice grain flows out from the inner peripheral surface of the branch (1), and the rice grain is discharged from the branch incision hole (2). Under the cutting action of being cut off from the grains, it is discharged from the branch incision hole (2) and falls between the outer peripheral surface of the cylindrical screen (1) and the outer cylinder (5) and is taken out from the outlet (6). Those that are not discharged from the branch incision hole (2) descend between the inner peripheral surface of the cylindrical screen (1) and the rotating body (3) and are discharged from the discharge port (7). Single grains from the beginning and those that have become single grains due to the excision action of branch stalks are taken out in the process of flowing down and the processing capacity is greatly increased.
