[0001]
BACKGROUND OF THE INVENTION
The present invention is equipped in a state extending over a pair of opposite sides of the storage space in a plan view in the upper side portion of the storage space having a rectangular plan view for storing grains for drying or storage, A main traveling body that is reciprocatingly driven along the longitudinal direction of the pair of side portions is provided, and an auxiliary traveling body is supported on the main traveling body so as to be capable of reciprocating driving along a direction orthogonal to the traveling direction. The present invention also relates to a grain stirring device in a grain storage facility in which a plurality of grain stirring augers are suspended and supported on the auxiliary traveling body in a state of being spaced apart in the running direction.
[0002]
[Prior art]
Conventionally, as a grain stirring device in the grain storage facility having the above-described configuration, there has been a configuration shown in Japanese Patent Laid-Open No. 2000-23556.
That is, a pair of grain stirring augers are supported in a suspended position on the auxiliary traveling body (referred to as a Y-direction moving carriage in the above publication), and a plurality of augers for driving each grain stirring auger individually. Each of the electric motors for driving is arranged in a state where the motor output shaft is aligned in the horizontal position on the upper side of the grain stirring auger with the motor output shaft facing the same vertical direction as the axis of the grain stirring auger. The grain auger is linked to the auger drive chain, and the power of the electric motor is transmitted through the auger drive chain so that the grain auger is rotated around the vertical axis. It was.
[0003]
In the conventional configuration, the auxiliary traveling body (referred to as an X-direction moving carriage in the above publication) is provided with traveling wheels and is supported to be movable relative to the main traveling body. A pair of transverse drive chains are fixed at appropriate locations on the auxiliary traveling body, and the transverse drive chains are supported by the main traveling body at both ends of the moving range of the auxiliary traveling body. The auxiliary traveling body is stretched while being wound around each sprocket, and one of the sprockets is driven by a traverse electric motor and the traverse drive chain is reciprocated in the longitudinal direction. It was the structure which made it travel reciprocatingly.
[0004]
Further, in the above-described conventional configuration, the pair of grain stirring augers can be freely moved in the moving direction of the main traveling body so as to allow the backward movement with respect to the movement resistance of the grains accompanying the traveling of the main traveling body. It is supported to become. In other words, each grain auger, an electric motor for driving the auger for driving the grain auger, and a support member that integrally supports the chain interlocking mechanism and the like (referred to as a screw support portion in the above publication) ) Is supported so as to be swingable around a horizontal axis so as to be swingable in the moving direction of the main traveling body with respect to the auxiliary traveling body. Each grain auger is provided separately, and each grain auger is supported in a swingable manner in an independent state.
[0005]
[Problems to be solved by the invention]
The grain storage facility configured as described above has the following disadvantages and has room for improvement.
That is, in the above conventional configuration, the power of the electric motor for driving the auger is transmitted through the auger driving chain, and the grain stirring auger is driven to rotate around the vertical axis. As the auger for agitation is driven for a long time, the auger drive chain extends in the longitudinal direction, and the chain is stretched between the sprocket on the electric motor side and the sprocket on the grain agitation auger side. May loosen. In such a case, maintenance work is required to adjust the tension of the chain, but the chain will also grow with subsequent use, so the maintenance work described above is frequently performed every short period of time. There is annoyance that needs to be repeated.
[0006]
The grain storage facility having the above-described configuration is configured as a large-scale facility so that a large amount of grain can be stored, and the auxiliary traveling body as described above is located above the stored grain. Since it is provided by being positioned, it is often provided at a high place of about 5 to 6 meters from the floor surface. Then, for example, when grain is not stored in the storage space, the maintenance work as described above is a work at a high place, so that the work is difficult to perform.
In addition, when grain is stored in the storage space and agitation processing is required, if such maintenance work is required, the agitation action on the stored grain is appropriate during the maintenance work. There was a disadvantage that could not be executed.
[0007]
Even in the configuration in which the auxiliary traveling body is moved by driving the traverse electric motor, the power is transmitted through the traverse drive chain. Thus, since the transmission configuration uses the chain, the electric motor for stirring is used. Similar to the drive structure of a grain auger driven by a motor, there is a need for frequent maintenance work, which is a troublesome work at a high place, in order to adjust the tension as the chain stretches. There is a disadvantage that the stirring action on the stored grain cannot be performed properly during the work.
[0008]
In the above-described conventional configuration, the pair of grain stirring augers are each configured to be supported so as to be freely movable in the moving direction of the main traveling body. On the other hand, even if the grain stirring auger receives movement resistance due to the grain and causes a movement delay, the grain stirring auger is prevented from being damaged by receiving excessive force due to the movement of the main traveling body. It is a thing.
[0009]
By the way, the movement resistance by the grain with respect to each of the pair of grain stirring augers is not always constant, and a difference may occur in the movement resistance received by each grain stirring auger. For example, one grain auger is positioned near the side wall of the storage space, while the other grain stirring auger is positioned on the inner side of the storage space away from the side wall. Is traveling along the side wall, the grain stirring auger located near the side wall has a greater movement resistance as described above than the grain stirring auger located on the inner side. .
In other words, the grain auger is rotated around the axis of the vertical axis to agitate the grains while the surrounding grains are lifted upwards, and with the running of the main traveling body while performing such agitation. However, the grain auger located on the inward side does not have a member that restricts the upward lifting of the grain around it, and the grain lifted upward is the grain agitation. The auger for grain agitation located near the side wall escapes toward the side wall side because the side wall is present near the auger for grain agitation. In other words, it flows to the front side in the moving direction of the grain stirring auger and increases the movement resistance when moving along with the traveling of the main traveling body. As a result, the grain stirring auger located near the side wall has a greater movement resistance as described above than the grain stirring auger located on the inner side.
[0010]
Then, due to such a large movement resistance, when the grain stirring auger is in a state of being largely moved and retracted with respect to the main traveling body, for example, a state in which the grain stirring auger is largely swung around the upper side and inclined. There is a risk that the grain agitation may not be properly performed.
That is, in the above conventional configuration, for example, when one of the grain stirring augers moves near the side wall, even though the other grain stirring auger exhibits a proper stirring action, Grain stirring auger that moves near the side wall is caused by the floating state of the grain stirring auger, such as the movement resistance increases and the main traveling body moves largely to prevent proper stirring of the grain. As a result, there is a risk that the agitation processing for the stored grain may not be performed properly.
[0011]
If the grain stirring auger is swung and tilted greatly, the main traveling body is temporarily stopped, and when the grain stirring auger returns to the original state in which the grain stirring auger is close to the vertical posture, Although the structure which controls the driving | running | working state of a main traveling body so that the movement of a body may be resumed is considered, since it is a case where it comprises in this way, each auger for grain stirring is provided independently freely, respectively. , Restoring force toward the vertical posture is restored to a small level, and the movement stop time until the main traveling body starts traveling becomes longer, and as a result, the stirring process for the stored grain cannot be properly performed. .
[0012]
This invention is made paying attention to this point, and the objective is to provide the grain stirring apparatus in the grain storage facility which can perform the stirring process with respect to the stored grain appropriately.
[0021]
[Means for Solving the Problems]
  Claim1The grain agitation device in the grain storage facility described above is provided at the upper side portion of the storage space having a rectangular shape in plan view for storing grains for drying or storage, and on a pair of sides of the storage space in plan view. A main traveling body that is equipped in a spanning state and is reciprocally driven along the longitudinal direction of the pair of side portions is provided, and the main traveling body is capable of reciprocating drive traveling along a direction orthogonal to the traveling direction. Auxiliary traveling bodies are supported by the plurality of grain stirring augers in a suspended state supported by the auxiliary traveling bodies in a state of being spaced apart in the traveling direction. Each is suspended and supported by the auxiliary traveling body so as to be freely movable in the traveling direction of the main traveling body, and is connected by a connecting body so as to float integrally in the traveling direction of the main traveling body. Features .
[0022]
That is, each of the plurality of grain stirring augers is suspended and supported by the auxiliary traveling body so as to be freely movable in the traveling direction of the main traveling body, so that the grain stirring auger is moved by the grains when the main traveling body is driven. Even if there is a delay in movement due to resistance, it is possible to prevent the grain stirring auger from receiving an excessive force and being damaged by the driving traveling of the main traveling body.
[0023]
And since each of the plurality of grain stirring augers is connected by the connecting body so as to move freely in the traveling direction of the main traveling body, any one of the plurality of grain stirring augers is stored. Even if it is moving along the vicinity of the side wall of the space, it is possible to appropriately perform the stirring process on the stored grain.
For example, one of a plurality of grain agitation augers is moving near the side wall of the storage space, and the other grain agitation auger is in the storage space away from the side wall. In the case where the main traveling body is traveling along the side wall while being located on the inner side, as described above, the grain stirring auger located near the side wall is located on the inner side. Compared to the grain auger that is located, the resistance to movement of the grain is increased, and due to such a large movement resistance, the main traveling body tries to move backward and largely move backward, but at this time, The grain auger located on the inward side has less movement resistance than the grain auger located near the side wall, so the force acting so as to greatly move backward as the main traveling body travels is small.
[0024]
And since each of the plurality of grain augers for agitation is connected by a connecting body so as to float in the running direction of the main traveling body, the grain auger for agitation located near the side wall is used for traveling the main traveling body. On the other hand, the grain auger located on the inner side restrains each other so as to suppress such backward displacement and is positioned near the side wall. Therefore, it is possible to prevent the grain auger for the grain agitation from being largely retreated and to appropriately perform the agitation process on the stored grain.
[0025]
Further, for example, even if each of the plurality of grain stirring augers is in a state of being moved backwardly and displaced with respect to the traveling of the main traveling body, the plurality of grain stirring augers are connected by the connecting body. Therefore, the restoring force toward the vertical posture is increased, the original posture can be restored as soon as possible, and the stored grain can be appropriately stirred.
[0026]
As a result, in order to avoid the grain stirring auger from being damaged by receiving excessive force due to the driving of the main traveling body, the grain stirring auger is provided so as to be freely movable. Due to the free configuration, it is possible to eliminate the conventional disadvantage of being unable to properly stir the stored grain and properly stir the stored grain. It became possible to provide a grain agitation device in a grain storage facility.
[0027]
  Claim2The grain stirring device in the grain storage facility described in claim1In accordance with the detection information of the movement detection means, the movement detection means for detecting whether or not the amount of movement along the traveling direction of the main traveling body from the vertical posture in the grain stirring auger exceeds a set amount, And a moving operation means for stopping the driving travel of the main traveling body when the idle amount exceeds the set amount and resuming the driving travel of the main traveling body when the idle amount returns to a state smaller than the set amount. It is characterized by being.
[0028]
That is, it is detected by the movement detecting means whether or not the amount of movement along the traveling direction of the main traveling body exceeds the set amount from the vertical posture in the grain stirring auger. The moving operation means has a movement delay due to the movement resistance of the grain stirring auger as the main traveling body is driven, and the amount of movement is determined based on the detection information of the movement detecting means. When it is determined that the set amount has been exceeded, the traveling of the main traveling body is stopped. Then, as a result of stopping the traveling of the main traveling body, the grain stirring auger returns to the vertical posture, and when the swing amount returns to a state smaller than the set amount, the traveling of the main traveling body is resumed. .
[0029]
For example, if the main traveling body is configured not to stop traveling, the grain auger for agitation moves largely and an excessive force is applied, or the stored grain cannot be properly stirred. However, according to the above configuration, such inconvenience can be avoided in advance.
[0030]
  In order to avoid the inconveniences as described above, the connecting body is configured such that each of the plurality of grain stirring augers floats integrally in the traveling direction of the main traveling body even if the traveling of the main traveling body is stopped. Since the recovery force toward the vertical posture of the grain stirring auger is increased, the travel stop time until the main traveling body starts running after returning to the original posture is as short as possible. Thus, it is possible to properly perform the stirring process on the stored grain,1A suitable means for carrying out is obtained.
The grain agitation device in the grain storage facility according to claim 3 is the top of the storage space in which the grain shape is stored for drying or storage in the first or second aspect of the rectangular storage space. A main traveling body that is equipped in a state extending across a pair of opposing side portions of the storage space and that travels reciprocally along the longitudinal direction of the pair of side portions is provided. Auxiliary traveling body is supported so as to be capable of reciprocating drive along a direction orthogonal to the vertical direction, and a plurality of grain stirring augers are suspended and supported on the auxiliary traveling body in a state of being arranged at intervals in the traveling direction. In claim 1 or 2, the electric motor that drives the traveling wheels of the auxiliary traveling body is arranged in a side-by-side configuration with respect to the traveling wheels to be driven, and the output shaft is the driving target. Connect directly to running wheel State, characterized in that provided in the auxiliary traveling body.
In other words, since the output shaft of the electric motor and the traveling wheels of the auxiliary traveling body are linked and linked, the electric motor of the electric motor can be driven even if the driving wheels of the auxiliary traveling body are rotated for a long time. The connection state between the output shaft and the traveling wheels of the auxiliary traveling body does not change, and unlike the chain type transmission mechanism as in the conventional configuration, adjustment of the tension of the chain, which is a troublesome operation at a high place, etc. Maintenance work need not be frequently performed every short period, and the frequency of such maintenance work can be reduced.
In other words, when the output shaft of the electric motor and the grain stirring auger are linked and connected, for example, a gear meshing type transmission mechanism may be adopted instead of the conventional chain type transmission mechanism. Even in such a gear meshing type transmission mechanism, there is a risk that the gear interlocking with the gear may be worn if the rotation of the grain auger for a long time is executed, and it is necessary to periodically lubricate to prevent wear. On the other hand, the number of operations increases. However, if the configuration is such that the output shaft of the electric motor and the traveling wheels of the auxiliary traveling body are directly connected, chain elongation, wear at the contact portion of the gear, etc. may occur. Therefore, it is not necessary to perform maintenance work for inspection over a long period of time, and the number of maintenance work can be reduced.
Therefore, according to the configuration of claim 3, the frequency of performing maintenance work on the transmission mechanism between the electric motor and the traveling wheels of the auxiliary traveling body can be reduced, and the grain is stored in the storage space and the stirring process is performed. The grain that has been stored is reduced by the maintenance work on the transmission mechanism between the electric motor and the traveling wheels of the auxiliary traveling body, and the stirring action on the grain cannot be properly performed. It has come to be able to provide a grain agitation device in a grain storage facility that makes it possible to appropriately carry out the agitation process.

This auger support frame F is a main frame formed in a rectangular frame shape in plan view that is pivotally supported relative to a lateral support shaft 127 supported by a vertical plate member 117 in the main traveling body 101. Part 128, motor support part 129 fixed to main frame part 128, and bearing part 130. The motor support part 129 is arranged so that its output shaft 126 protrudes downward. The agitating electric motor M3 is fixedly supported, and the bearing agitating portion 130 is configured to rotatably support the grain agitating auger 103 while supporting a load in the vertical direction. The output shaft 126 of the electric motor M3 and the upper end of the grain stirring auger 103 are directly connected by a flange-type connector 131.
[0049]
The main frame portion 128 is configured to be pivotally supported by the support shaft 127 at a position near the upper end portion thereof, and the position of the center of gravity of the electric motor M3 for stirring is more than the axis P of the support shaft 127. It is configured to be positioned on the lower side, and when the grain stirring auger 103 is tilted in any direction from the vertical posture, the restoring force to return toward the vertical posture is increased.
[0050]
Each of the pair of grain stirring augers 103 is connected by a connecting body so as to float (oscillate) integrally in the traveling direction of the main traveling body 101. In other words, as shown in FIGS. 10, 14, and 15, a connecting body 132 is installed over the main frame portions 128 of the auger support frame F that integrally supports the grain stirring augers 103. The connecting body 132 is connected and fixed to each main frame portion 128 by welding, and is configured to swing in an integrated state.
[0051]
Further, the amount of free movement along the traveling direction of the main traveling body 101 from the vertical posture of the grain stirring auger 103 to a position on the opposite side of the auxiliary traveling body 102 from the side where the electric motor M2 for traversing is installed in the X direction. An inclination / inclination sensor SE is provided as an idle detection means for detecting whether or not the swing amount) exceeds a set amount. That is, as shown in FIGS. 17 and 18, the main frame portion 128 that swings around the horizontal axis P together with the grain stirring auger 103 is tilted so as to swing integrally with the mounting plate 133. A sensor SE is attached. On the other hand, the support shaft 127 for swingably supporting the grain stirring auger 103 is prevented from rotating by the fixing pin 134 so that it cannot be rotated relative to the vertical plate member 117. A substantially V-shaped detection tool 136 acting on the detection piece 135 of the tilt sensor SE is supported on the shaft 127 in a fixed position.
When the grain stirring auger 103 swings around the horizontal axis in any direction from the vertical posture, the tilt sensor SE swings integrally with the swinging auger 103, but the detected tool 136 is fixed in posture. Therefore, the tilt sensor SE is turned on when the detection piece 135 of the tilt sensor SE is pushed by the tool 136 to be detected and the swing amount exceeds the set value in accordance with the change in the posture of the grain stirring auger 103. Thus, the inclination is detected.
[0052]
The stirrer 10 having such a configuration drives the electric motor M1 for traveling so that the main traveling body 101, the auxiliary traveling body 102, and each of the grain stirring augers 103 are integrated along the Y direction. By stopping the driving of the electric motor for traveling and driving the electric motor M2 for lateral movement, the auxiliary traveling body 102 and each of the grain stirring augers 103 are moved in the X direction. As shown in FIG. 20, based on command information such as stirring start and end from the upper computer CO that manages the entire equipment, detection information by each limit switch group SW, etc. The grain stirring augers 10 are controlled by controlling the operation of the electric motor M1, the transverse electric motor M2, and the electric motor M3 for stirring. The, as shown in FIG. 19, the control unit H is provided for controlling the operation to be able to stir the grain that is stored over substantially the entire area of the storage space Di while sequentially moving.
[0053]
That is, in the initial state of the stirring operation, each grain stirring auger 103 is positioned at a corner (standby position) of the target area, and each of the grain stirring augers 103 is driven by driving each of the stirring electric motors M3. While agitating, the traveling electric motor is driven to cause the main traveling body 101 to travel to move each grain stirring auger 103 in the Y direction. When it is detected by the limit switch SW1 that the vehicle has traveled to the movement limit, the sideways electric motor M2 is driven for a set time, and the auxiliary traveling body 102, that is, each grain stirring auger 103 is moved by a predetermined pitch in the X direction. After the movement, the traveling electric motor M1 is driven to cause the main traveling body 101 to travel in the opposite direction to move each grain stirring auger 103 in the Y direction (reverse direction). When such traveling is repeated and the limit switch SW3 detects that the auxiliary traveling body 102 has reached the movement limit, the same reciprocating traveling is performed by shifting the position by half a pitch as shown by the broken line in FIG. When returning to the standby position, the stirring process is terminated. Such an operation is repeatedly executed until a stirring end command is issued.
[0054]
When the main traveling body 101 is driven by driving the electric motor M1 for traveling to move each grain stirring auger 103 in the Y direction, the movement received from the grains as shown by the phantom lines in FIG. Each grain stirring auger 103 may be swung backward and tilted due to resistance. However, when it is detected that the amount of inclination exceeds a set value based on the detection information of the inclination sensor SE, When the control device H stops driving the electric motor M1 for traveling at that time and returns until the inclination amount of each grain stirring auger 103 becomes a value smaller than the set value, the electric motor M1 for traveling travels. The drive is resumed.
At this time, as described above, each grain auger 103 is connected by the connecting body 132 so as to swing integrally in the traveling direction of the main traveling body 101. The restoring force is increased, and it is restored as soon as possible until the inclination amount becomes smaller than the set value.
Therefore, using the control device H, based on the detection information of the inclination sensor SE, when the idle amount exceeds the set amount, the driving traveling of the main traveling body 101 is stopped, and the swing amount is smaller than the set amount. When returning to, the moving operation means for resuming the driving traveling of the main traveling body is constituted.
