As shown in fig. 1, a grain dryer 1 of the present invention includes: a storage part 2 for storing grains; a drying section 3 for drying the grains; a collecting and collecting part 4 for collecting the grains descending from the drying part 3; a trough discharge 5 for returning the grains collected in the trough 4 to the storage 2.
The storage part 2 is located at an upper side and accommodates grains.
The drying unit 3 is provided below the storage unit 2, and heats the grains descending from the storage unit 2 by a circulation operation, for example, with far infrared rays or hot air, thereby reducing the moisture contained in the grains.
The trough 4 is provided below the drying unit 3, and collects grains descending from the drying unit 3 by the circulation operation.
The trough discharger 5 extends the side surfaces of the storage unit 2, the dryer 3, and the trough collector 4 in the vertical direction, and conveys the grains collected in the trough collector 4 upward and discharges the grains to the upper part of the storage unit 2. In addition, an inlet 6 for introducing the grain dried by the grain dryer 1 is provided at a lower portion of the trough discharge portion 5. The grains introduced from the inlet 6 are conveyed upward by the trough 5 and discharged to the upper part of the storage part 2. A feeding portion for feeding out the grains contained therein is provided above the unloading portion 5.
The grain dryer 1 configured as described above circulates grains in the order of the storage unit 2, the drying unit 3, the trough collecting unit 4, and the trough discharging unit 5.
As shown in fig. 1, the moisture measuring device 10 of the present invention is provided below the side surface of the trough discharger 5. The moisture measuring device 10 measures moisture contained in grains of a part of the grains transferred upward in the trough discharge portion 5 at predetermined time intervals. The grain dryer 1 detects the amount of moisture or the moisture percentage that reaches the set moisture of the grains measured by the moisture measuring device 10 during the drying operation of the grains, and can stop the operation of the drying unit 3, the trough collecting unit 4, and the trough discharging unit 5.
As shown in fig. 2 to 4, the moisture measuring device 10 includes: a housing 20 formed so as to protrude from a side surface of the trough discharger 5; a moisture measuring means 30 provided in the casing 20 for measuring moisture contained in the grains; a grain supply means 40 for supplying the grains to the moisture measuring means 30.
As shown in fig. 2, the housing 20 has a box shape extending in the vertical direction. As shown in fig. 3, the housing 20 is attached to the side wall of the trough discharger 5 in a posture in which the first side surface 21 faces the trough discharger 5. The bottom surface 22 of the housing 20 is inclined downward from a second side surface 23 opposite to the first side surface 21 toward the first side surface 21. A third side surface 24 of the housing 20 adjacent to the first side surface 21 is provided with an observation window 24a for allowing the inside of the housing 20 to be visually recognized from the outside. As shown in fig. 4, the interior of the housing 20 is partitioned by a partition wall 26 into a first space 20a on the third side 24 side and a second space 20b on the 4 th side 25 side opposite to the third side 24. An inlet 21a for taking in grains is provided at an upper portion of the first side surface 21 of the housing 20 on the first space 20a side. Further, a discharge port 21b for discharging grains whose moisture is measured by the moisture measuring means 30 is provided in a lower portion of the first side surface 21 of the casing 20 on the first space 20a side.
The moisture measuring mechanism 30 includes: a plurality of moisture measuring parts 31 which are arranged according to the size of the grains for measuring moisture and are used for crushing the grains; a motor 32 as a power source for driving the moisture measuring units 31; and a driving force transmission mechanism 33 for transmitting the driving force of the motor 32 to the plurality of moisture measurement units 31.
The plurality of moisture measuring units 31 include: a first rotary shaft 31a and a second rotary shaft 31b driven by receiving a driving force of the motor 32; a first roller 31c supported by the first rotating shaft 31 a; a second roller 31d and a third roller 31e supported by the second rotating shaft 31 b; and a measuring section 31f for measuring the electric resistance between the first roller 31c and the second roller 31d or between the first roller 31c and the third roller 31 e.
The first rotation shaft 31a and the second rotation shaft 31b are each made of metal, and the respective central axes are arranged in parallel to each other in the horizontal direction in the first space 20 a. One end side of each of the first rotating shaft 31a and the second rotating shaft 31b is rotatably supported by the partition wall 26.
The first roller 31c is a metal cylindrical member fixed to the outer peripheral portion of the first rotating shaft 31 a. The outer periphery of the first roller 31c is subjected to, for example, rolling knurling such as a cross-hatch. In addition, a rotating brush 31c1 and a scraper 31c2 for removing pieces of grain adhering to the outer peripheral surface of the first roller 31c are provided in the vicinity of the first roller 31 c.
The second roller 31d is a metallic cylindrical member fixed to the outer peripheral portion of the second rotating shaft 31 b. The axial dimension of the second roller 31d is substantially half of the axial dimension of the first roller 31 c. As shown in fig. 5, a groove 31d1 is formed in the outer peripheral portion of the second roller 31d by, for example, rolling knurling such as a slant or flat mesh. The groove 31d1 is formed to have a depth dimension capable of crushing small grains such as rice and wheat between the outer peripheral portion of the first roller 31c and the outer peripheral portion of the second roller 31 d.
The third roller 31e is a metallic cylindrical member fixed to the outer peripheral portion of the second rotating shaft 31 b. The axial dimension of the third roller 31e is substantially half of the axial dimension of the first roller 31c, and is substantially the same as the axial dimension of the second roller 31 d. As shown in fig. 5, a groove 31e1 is formed in the outer peripheral portion of the third roller 31e by, for example, a cutting-type knurling process such as a slant-mesh or flat-mesh. The groove 31e1 is formed to have a depth dimension larger than the groove 31d1 of the second roller 31d so as to crush large grains such as soybeans and corn between the outer peripheral portion of the first roller 31c and the outer peripheral portion of the third roller 31 e.
As shown in fig. 5, the second roller 31d and the third roller 31e are aligned in the axial direction of the second rotation shaft 31 b. In the present embodiment, the plurality of moisture measuring portions 31 are defined as a first moisture measuring portion 31A between the outer periphery of the first roller 31c and the outer periphery of the second roller 31d, and a second moisture measuring portion 31B between the outer periphery of the first roller 31c and the outer periphery of the third roller 31 e.
In addition, a fixed brush 31d2 and a scraper 31d3 for removing pieces of cereal grains adhering to the outer peripheral surface of the first roller 31c are provided in the vicinity of the second roller 31d and the third roller 31 e.
When foreign matter such as stone or metal pieces different from grains is supplied to each of the plurality of water content measuring units 31, the foreign matter removing structure is provided for removing the foreign matter. The foreign matter removal structure is formed by cutting a part of the outer peripheral portion of the first roller 31c, a part of the outer peripheral portions of the second roller 31D and the third roller 31e, or a part of the outer peripheral portions of the first roller 31c, the second roller 31D and the third roller 31e into a flat surface, and applying a so-called D-cut process.
In the plurality of moisture measuring units 31, if foreign matter is supplied in a state where the first rotating shaft 31a and the second rotating shaft 31b are driven to measure moisture of grains, the foreign matter enters the rollers 31c, 31d, and 31e to restrict the rotation of the first rotating shaft 31a and the second rotating shaft 31 b. In the plurality of moisture measuring units 31, a state in which the rotation of the first and second rotating shafts 31a and 31b is restricted is detected, and the first and second rotating shafts 31a and 31b are rotated in a direction opposite to the rotating direction of the first and second rotating shafts 31a and 31b when moisture is measured. Thus, the foreign matter introduced into the moisture measuring section 31 falls into the gap formed by the D-cut between the first roller 31c and the second roller 31D or between the first roller 31c and the third roller 31e, and is removed from the moisture measuring section 31.
Measuring unit 31f measures the resistance between first measurement point 31f1 connected to first rotation shaft 31a and second measurement point 31f2 connected to second rotation shaft 31 b. The measuring section 31f forms an electric circuit between the first measurement point 31f1 and the second measurement point 31f2 in a state where the grain is pinched between the first roller 31c and the second roller 31d or between the first roller 31c and the third roller 31 e. The measuring unit 31f measures the moisture content or moisture percentage of the grain by detecting the resistance value of the resistance between the first measuring point 31f1 and the second measuring point 31f 2.
As shown in fig. 3 and 4, the motor 32 is provided above the first space 20a and is fixed to the partition wall 26.
The driving force transmission mechanism 33 is composed of a plurality of gears, and is coupled to the rotation shaft of the motor 32, and also coupled to the first rotation shaft 31a and the second rotation shaft 31 b. The driving force transmission mechanism 33 is provided in the second space 20b and is fixed to the partition wall 26.
As shown in fig. 3, the grain supply mechanism 40 includes: a hopper 41 into which grains are fed; a communication member 42 having a plurality of communication paths 42a and 42b formed therein for communicating the inside of the hopper 41 with the plurality of moisture measuring units 31, respectively; a grain moving plate 43 as a plurality of grain moving means for moving the grains fed into the hopper 41 to a predetermined communication path in the hopper 41.
The hopper 41 is provided on the trough discharge portion 5 side at the upper side of the housing 20. The hopper 41 has a cylindrical shape with one end closed and the other end open. A part of the hopper 41 protrudes toward the unloading unit 5 through the intake port 21a, and one end side of the cylindrical shape is inclined downward. The opening of the other end side of the hopper 41 is directed obliquely upward in the trough-discharging portion 5. The hopper 41 is provided with a closing plate 41a that closes a part of the opening on the other end side in order to suppress the amount of grain put into the hopper 41 from the trough discharge portion 5.
The communication member 42 is a member in which a passage is formed to communicate one end of the hopper 41 with the upper side of the plurality of moisture measuring units 31. Specifically, a first communication passage 42a that communicates the hopper 41 with the first moisture measuring section 31A is formed on the right side as viewed from the first side surface 21 side of the housing 20, and a second communication passage 42B that communicates the hopper 41 with the second moisture measuring section 31B is formed on the left side. Further, the end of the communicating member 42 on the hopper 41 side is connected to the upper side of the one end surface of the hopper 41, and as shown in fig. 6, a first communication hole 42a1 of the first communication passage 42a is formed on the right side of the upper portion of the one end surface of the hopper 41, and a second communication hole 42b1 of the second communication passage 42b is formed on the left side of the first communication hole 42a 1. In one end surface of the hopper 41, the second communication hole 42b1 opens radially inward of the radial arrangement of the first communication hole 42a 1.
As shown in fig. 7 and 8, the plurality of grain-moving plates 43 are each formed of a disk-shaped member having an outer diameter substantially equal to the inner diameter of one end side of the hopper 41, and are supported by the hopper 41 so as to be rotatable about the radially central portion and detachably attachable thereto. The grain moving plate 43 is capable of rotating forward and backward by power transmitted from the motor 32. The grain moving plate 43 holds grains fed into the hopper 41, and is provided with a holding opening 43a for moving the grains along one end surface in the hopper 41 by a rotational operation. The holding opening 43a is formed by cutting the outer periphery of the grain moving plate 43 or by punching a predetermined radial position. The grain moving plate 43 determines the size and position of the holding opening 43a according to the size of the grain to be moved and the positions of the communication holes 42a1 and 42b1 at one end surface in the hopper 41. The holding opening 43a is formed to hold one grain.
In the present embodiment, the grain moving plate 43 uses a first grain moving plate 43-1 for moving small grains such as rice, wheat, and the like to the first communicating hole 42a1 and a second grain moving plate 43-2 for moving large grains such as soybean, corn, and the like to the second communicating hole 42b 1. The first grain moving plate 43-1 and the second grain moving plate 43-2 are replaced with the hopper 41 according to the size of the grain whose moisture is measured.
The first grain moving plate 43-1 has a holding opening 43a formed by cutting the outer peripheral portion. The first grain moving plate 43-1 has a plurality of holding openings 43a formed at predetermined intervals in the circumferential direction.
The second grain moving plate 43-2 has a holding opening 43a formed radially inward of the holding opening 43a in the first grain moving plate 43-1. The second grain moving plate 43-2 is formed with a holding opening 43a in the circumferential direction. The holding opening 43a of the second grain moving plate 43-2 is a larger opening than the holding opening 43a of the first grain moving plate 43-1.
In the moisture measuring apparatus 10 configured as described above, when the grain drying machine 1 performs an operation of drying the grains, the grain moving plate 43 is attached to the hopper 41 in accordance with the type of the grains to be dried. When the grain to be dried is small grain such as rice or wheat, the first grain moving plate 43-1 is attached to the hopper 41. When the grain to be dried is large-grain grains such as soybeans and corn, the second grain moving plate 43-2 is attached to the hopper 41.
In the moisture measuring device 10, during the grain drying operation by the grain dryer 1, the moisture contained in the grains is measured by rotating the grain moving plate 43 and driving the moisture measuring mechanism 30 while the grains are charged into the hopper 41.
When the grain moving plate 43 is rotated counterclockwise in the hopper 41 into which grains are put, the holding opening 43a of the grain moving plate 43 passes through the lower side in the hopper 41, and one grain in the hopper 41 is held in the holding opening 43 a.
One grain held in the holding opening 43a moves upward along one end face in the hopper 41 by the rotation of the grain moving plate 43. When the grain held in the holding opening 43a moving along one end surface in the hopper 41 is aligned with the positions of the communication holes 42a1 and 42B1 at the one end surface in the hopper 41, the grain is supplied to the moisture measuring mechanism 30 through the communication paths 42a and 42B, and either of the moisture measuring portions 31A and 31B measures moisture.
Here, when the first grain moving plate 43-1 is mounted in the hopper 41, the holding opening 43a is provided in the outer peripheral portion, and therefore, when moving counterclockwise from the lower side in the hopper 41, first passes through the first communication hole 42a1 as shown in fig. 9. Therefore, the grain S held in the holding opening 43a is supplied to the first moisture measuring station 31A through the first communicating hole 42a1 and the first communicating path 42 a. The grain S supplied to the first moisture measuring section 31A is crushed between the first roller 31c and the second roller 31d, and the electric resistance is measured to measure the moisture contained therein. The grains S crushed between the first roller 31c and the second roller 31d are discharged from the discharge port 21b to the outside of the casing 20.
In addition, when the second grain moving plate 43-2 is mounted in the hopper 41, the holding opening 43a is provided radially inward of the holding opening 43a of the first grain moving plate 43-1, and therefore, when moving counterclockwise from the lower side in the hopper 41, first passes through the second communication hole 42b1 as shown in fig. 10. Therefore, the grains L held in the holding opening 43a are supplied to the second water content measuring part 31B through the second communication hole 42B1 and the first communication path 42B. The grain L supplied to the second moisture measuring portion 31B is crushed between the first roller 31c and the third roller 31e, and the electric resistance is measured, thereby measuring the moisture contained therein. The grain L crushed between the first roller 31c and the third roller 31e is discharged from the discharge port 21b to the outside of the casing 20.
Thus, according to the water content measuring apparatus of the present embodiment, the holding openings 43a of the plurality of grain moving plates 43 are formed to have different sizes depending on the size of grains to be held, and initially pass through the communication holes 42a1 and 42b1, which are different from each other, at the time of a predetermined operation.
Accordingly, when the size of the grain to be included in the moisture content is changed, the grain loaded into the hopper 41 can be supplied to the corresponding moisture content measuring unit 31 by changing only the grain moving plate 43, and therefore, the number of components can be reduced, and erroneous setting when the moisture content of the grain is measured can be prevented.
Further, each of the plurality of grain moving plates 43 is formed in a disk shape, and is rotated about a center portion in a radial direction in the hopper 41 as a predetermined operation, and holding openings 43a are formed at positions different from each other in the radial direction, and each of the plurality of communication holes 42a1, 42b1 is provided at a position corresponding to the holding opening 43a of each of the plurality of grain moving plates 43.
Accordingly, since the grain in the hopper can be moved to the communication holes 42a1 and 42b1 by the grain moving plate 43 which is rotated, a large operation space is not required at the time of the operation of the grain moving plate 43, and the device can be miniaturized.
The plurality of moisture measuring units 31 each have a pair of rollers 31c, 31d, and 31e for crushing grains.
Thus, the size of the grain for measuring moisture can be changed by using the rollers having different shapes of the outer peripheral portion, and thus the setting change is facilitated.
In the above embodiment, the grain moving plate 43 is shown which moves the grains charged into the hopper 41 by the rotating operation, but the present invention is not limited thereto. The grain moving plate may be a grain moving plate that reciprocates in a predetermined direction in the hopper as long as the grain put into the hopper 41 can be moved.
In the above embodiment, the plurality of moisture measuring portions 31 are each configured by the first roller 31c and the second roller 31d, and the first roller 31c and the third roller 31e, which are paired, but the present invention is not limited thereto. The moisture measuring unit is not limited to one having a pair of rollers, as long as the member for measuring moisture is changed according to the size of grains.
In the above embodiment, the measurement of the moisture of grains of two sizes by the two moisture measurement units 31A and 31B, the two communication paths 42a and 42B, and the two grain moving plates 43-1 and 43-2 is shown, but the present invention is not limited thereto. The moisture of grains of 3 kinds or more may be measured by providing 3 or more moisture measuring parts, 3 or more communication paths, and 3 or more grain moving plates.
