  The present invention relates to a lifting device in a grain dryer or a hull sorter.

  For example, in a circulation type grain dryer, a cylindrical feeding valve that feeds the grain while rotating forward and backward is provided below the lower end joining part of the left and right grain flow passages of the drying chamber, and the grain fed from the feeding valve is placed on the upper side again. An elevator that is long up and down is provided along the dryer frame in order to return to the storage chamber. The elevating device stretches a belt with a bucket between pulleys arranged up and down, and scoops up grains that are sequentially fed below an elevator case that houses the bucket and the belt, and discharges them by reversing the bucket above. It is configured as follows.

  By the way, it is common not to ship with a long elevator case mounted on the machine frame like a grain dryer, but to separate and pack and ship the elevator independently (Patent Document 1).

  The lower pulley is provided on a support plate that can be moved up and down with respect to the case, and the adjustment plate is biased downward by a spring so that the screw shaft can be adjusted outside the elevator case. It is set as the structure which can change urging | biasing force arbitrarily provided (patent document 2).

Further, the elevator case is provided with a moisture detector for detecting the moisture of the grain. The moisture detector is configured to receive overflowing grains from the bucket and detect the moisture value of multiple grains, and is configured to easily accept the grains in the grain receiving portion of the moisture detector in a relatively short time. Therefore, there is one that forms a partition for throwing on the bucket (Patent Document 3).

The upper half case 18U Since the leading end side of the packing frame 93 is accommodated below the column members 93b, 93b... And the height can be attached to the side of the packing frame 93 in a protruding state, the length of the packing frame 93 is the upper half case 18U. The overall length can be made equal to the length of the lower half case 18L without depending on the length, and a common packing frame 93 can be obtained even if the model is different. In addition, the support members 93b, 93b,... Can be stored in a plurality of levels in a warehouse by stacking in the vertical direction, and such a multi-stage setting is possible even during transportation. You can get none.

  Next, the moisture meter 53 will be described.

  A hopper 95 of the moisture meter 53 is looked into the middle of the elevator 17, and a discharge end of the hopper 95 is formed at the start end side of a one-grain feeding portion 98 including a conveying plate 96 and a feeding roll 97 having a spiral strip formed on the outer periphery. Peep into. A pair of electrode rolls 99, 99 are provided below the transfer terminal part of the one-grain feeding part 98. The electric resistance value between the electrode rolls 99 and 99 is read, and is configured to be executed based on a predetermined conversion formula every time a predetermined number of grains (for example, 100 grains) is measured. The average value of the plurality of grains is adopted as the current measurement value and used for display output or drying control.

  The hopper 95 (grain receiving part) of the moisture meter 53 is provided at the interval between the forward and backward strokes of the bucket belt 20 or at a position where the bucket belt 20 enters the interval. Or the grain returned to the elevator case 18 at the time of throwing and feeding from the bucket 19 to the upper spiral is received. However, these overflowing grains become smaller as the efficiency of raising the bucket is reduced, and the time for detecting moisture of a predetermined number of grains becomes longer and hinders appropriate drying control.

  Therefore, as shown in FIG. 19, a part of the bucket 19 (for example, two) is configured as a special bucket 19 ′ in which a circular hole 19 a is formed as a grain overflow hole on the side surface. The circular hole 19a is provided on the moisture meter 53 on the side where the hopper 95 is present. The size (diameter) and the arrangement on the side wall of the bucket 19 are determined in relation to the grain moisture, the height of the moisture meter 53, and the like. That is, the bucket 19 ′ that has sprinkled the grains supplied to the lower part of the elevator case 18 of the elevator 17 gradually overflows from the circular hole in the ascending stroke, and still overflows even if the height of the moisture meter 53 is exceeded. It is provided so that it can flow. Therefore, a part of the overflowing grain from the hole 19a is taken into the moisture meter 53 main body from the hopper 95 of the moisture meter 53, and the measurement time is not increased. FIG. 20 is an example in which the time for incorporating the predetermined number of grains into the moisture meter with and without the hole 19a is compared. It is known that there is a difference of about 10 seconds in the average time of taking 100 grains, and the presence or absence of the holes 19a affects the measurement time. Although the circular hole 19a has been described in the above example, it may not be circular as long as the same effect is obtained.

  FIG. 21 shows the configuration of a throwing guide frame 100 that guides the grain thrown from the bucket 19 to the starting end of the upper transfer device 31 at the upper part of the elevator 17, and the inner surface of the throwing guide frame 100 having a rectangular cross section. In order to guide the grains from the bucket 19, an arc-shaped guide plate 101 is bonded and fixed by welding. At the joint portion 102 between the guide plate 101 and the guide frame 100, convex shapes 103, 103 are formed on the guide frame 100 side, and the convex shapes 103, 103 and the guide plate 101 are spot-welded. For this reason, the space portion 104 between the curved portion of the guide plate 101 and the corner portion of the guide frame 100 ensures communication with the outside air, and therefore does not cause an air reservoir, and thus has the following excellent effects. That is, the subassembly such as the spot welding is performed and the painting process is started. At this time, in the case where the coating liquid is submerged in a submerged state, if the space portion 104 is in an air accumulation state, a predetermined buoyancy action works. It is difficult to sink, and when hooks are locked and moved up and down, there is an unexpected sinking resistance, which makes it easy for the hook to come off. Air can enter and exit from 104.

  FIG. 22 shows a modification of the configuration of the slit 65 shown in FIG. That is, the front side and the back side of the drying chamber 3 are interchanged, and the elevator 17 is configured as a so-called rear elevator in front and rear, but the configuration of the slit 65 in FIG. In addition, since the 4 parts of the cereal collection room are not interchanged, there is room for improvement because the position of the slit 65 that should correspond to the back side of the far-infrared radiator 10 becomes the front side. Therefore, a first bonding plate 104 having a slit 65 ′ and a second bonding plate 105 not forming a slit are prepared, and the first in order to correspond to the back side of the far-infrared radiator 10 with the replacement of three parts of the drying chamber. The joining plate 104 is configured to be selectively replaced with openings 106 and 106 formed in advance on the front and rear walls of the four parts of the grain collection chamber. If it does in this way, slit 65 'can be located corresponding to the back side of far-infrared radiator 10, and it corresponds easily also to the above-mentioned back elevator type. In addition, if the slit 65 "is formed in the front and rear wall parts of the cereal collection room 4 part and the second joining plate 105 is joined to the slit non-use position, the recombination man-hour can be simplified.

  FIG. 23 relates to the improvement of the wedge and the wedge holder for assembling the tank side wall. The wedge 107 is formed by appropriately forming a thin plate shape into a tapered shape, and holding holes 108a and 108b are formed in the U-shaped holder 108. The wedge 107 is held through. The connecting portion 108c of the holder 108 is penetrated from the back surface side to the overlapping portion 109 of the wall body to be bonded and held, and holding holes 108a and 108b are provided in a protruding shape on the front surface side. One of the holding holes 108a and 108b has the same holding hole gap with respect to the other, the widths W and w are different, and the wedge 107 is driven from the wide width W side to the narrow width w side. Since the U-shaped holder 108 is employed, there is an effect that molding is easy and can be reliably fixed. In addition, the wedge 107 side has a symmetrical taper shape and can be reliably fixed while being simple in structure, and there is no distinction between the front and back sides and the upper and lower sides, and the symmetry and the shape make it easy to manufacture and work.

  In addition to forming the wedge 107 head flat, and forming it in a triangular shape as shown in FIG. 24 (b), driving can be performed in an oblique direction and workability at the wall can be improved.
