2. Description of the Related Art Conventionally, as a grain stirring device in a grain storage facility having the above-mentioned configuration, there has been a configuration disclosed in Japanese Patent Laid-Open No. 2000-23556. That is, the auxiliary traveling body (referred to as a Y-direction moving carriage in the above publication)
, A pair of grain stirring augers are supported in a drooping position.Each of the plurality of auger driving electric motors driving the respective grain stirring augers separately has a motor output shaft that is the axis of the grain stirring auger. It is arranged in the state of being aligned in the horizontal side part on the upper side of the grain stirring auger in a state of facing the same vertical direction as the core, and its motor output shaft and grain auger auger are interlocked and linked by an auger drive chain, The power of the electric motor is transmitted through the auger driving chain so that the grain stirring auger is rotationally driven around the vertical axis.

Further, in the above-mentioned conventional structure, the auxiliary traveling body (referred to as an X-direction moving carriage in the above publication) is provided with traveling wheels and is supported so as to be movable and movable with respect to the main traveling body. Both ends of the traverse drive chain are fixed to appropriate positions of the auxiliary traveling body, respectively, and the traverse drive chain is supported by the main traveling body at both ends of the movement range of the auxiliary traveling body. A pair of sprockets are stretched around each other, and one of the sprockets is driven by an electric motor for traverse to reciprocate the traverse drive chain in the longitudinal direction to assist. The traveling body was configured to reciprocate.

Further, in the above-mentioned conventional structure, the pair of grain stirring augers are individually arranged in the moving direction of the main traveling body to allow the backward movement with respect to the movement resistance of the grain accompanying the traveling traveling of the main traveling body. It is supported so that it can move freely. In addition, a supporting member for integrally supporting each grain stirring auger, an auger driving electric motor for driving the same, a chain interlocking mechanism, etc. (referred to as a screw supporting portion in the above publication). ) Is swingably supported around the horizontal axis so that it can swing in the moving direction of the main traveling body with respect to the auxiliary traveling body. The grain stirring augers are separately provided, and each grain stirring auger is configured to be swingably supported in an independent state.

[0005]

The grain storage facility having the above-mentioned structure has the following disadvantages.
There was room for improvement. That is, in the above-described conventional configuration, the power of the electric motor for driving the auger is transmitted through the auger driving chain to rotate the grain agitating auger about the vertical axis. The auger driving chain extends in the longitudinal direction as the stirring auger is rotationally driven for a long time, and the chain tension between the electric motor side sprocket and the grain stirring auger side sprocket is increased. May become loose. In such a case, maintenance work is required to adjust the tension of the chain, but the chain will expand again with subsequent use, so the maintenance work described above will be performed frequently every short period. There is the annoyance that it needs to be repeated.

Further, the grain storage facility having the above-mentioned 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 has a greater capacity than the stored grain. Since it is installed on the upper side,
It is often installed at a high place about 5 to 6 meters above the floor. Then, for example, when grains are not stored in the storage space, the above-described maintenance work is performed at a high place, which makes it difficult to perform the work. In addition, when such a maintenance work needs to be performed when the grains are stored in the storage space and the stirring process is required, the stirring action on the stored grains is properly performed during the maintenance work. There was a disadvantage that I couldn't do it.

Even in the structure in which the auxiliary traveling body is moved by driving the electric motor for traverse, power is transmitted through the chain for traverse drive, and the transmission structure using the chain in this manner causes stirring. Similar to the drive configuration of the grain stirring auger by the electric motor for the operation, it is necessary to frequently perform maintenance work, which is a troublesome work at high places, in order to adjust the tension of the chain as it stretches. However, there is a disadvantage that the stirring action for the stored grains cannot be properly performed during the maintenance work.

In the above conventional structure, the pair of grain stirring augers are individually supported so as to be freely movable in the moving direction of the main traveling body. Even if the grain agitating auger receives a resistance to movement due to grain and causes a delay in moving, the grain auging auger may be damaged by excessive force due to the traveling of the main traveling body. This is to avoid it.

By the way, the movement resistance of the grain to 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 stirring auger is located near the side wall of the storage space, while the other grain stirring auger is located on the inner side of the storage space away from the side wall. Is traveling along the side wall, the grain auger located near the side wall has a larger movement resistance as described above than the grain auger located on the inner side. . In addition, the grain stirring auger rotates around the longitudinal axis to stir the grains while lifting them around the vertical axis, and at the same time as the main traveling body travels while performing such stirring. However, the grain auger located on the inner side does not have a member around it that restricts lifting of the grain to the upper side. The auger for grain agitation located near the side wall can escape to the outer side over the entire circumference of the auger, but since the side wall is near, the grain lifted upwards escapes toward the side wall. Therefore, the grain stirring auger flows to the front side in the moving direction and increases the movement resistance when the main traveling body moves as the main traveling body travels. 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.

Due to such a large movement resistance, the grain stirring auger moves largely with respect to the main traveling body and retracts, for example, swings largely around the upper side and is inclined. In this case, there is a possibility that the stirring process of the grains cannot be performed properly. That is, in the above conventional configuration, for example, when one of the grain stirring augers moves near the side wall, while the other grain stirring augers exert an appropriate stirring action, The grain auger that moves near the side wall has a large movement resistance and moves a lot with respect to the main traveling body, which makes it impossible to properly perform grain agitation processing. Then, there is a possibility that the stirring process for the stored grains cannot be performed properly.

When the grain agitating auger swings greatly and is inclined, the traveling traveling of the main traveling body is temporarily stopped and the grain auger is returned to the original state in which it is close to the vertical posture. A configuration is conceivable in which the traveling state of the main traveling body is controlled so that the movement of the main traveling body is restarted, but even with such a configuration, each grain stirring auger is independently movably provided. As a result, the restoring force toward the vertical posture is small and the movement stop time before the main traveling body starts traveling becomes long, and as a result, the stirring process for the stored grains cannot be performed properly. Will be things.

The present invention has been made by paying attention to such a point, and an object thereof is to provide a grain stirring device in a grain storage facility capable of appropriately performing a stirring process on stored grains. It is in.

[0013]

According to a first aspect of the present invention, there is provided a grain agitating device in a grain storage facility, wherein a flat surface is provided at an upper side portion of a storage space having a rectangular shape in plan view for storing grains for drying or storage. A main traveling body that is equipped in a state of extending over a pair of opposing side portions of the storage space in view and is reciprocally driven along the longitudinal direction of the pair of side portions is provided, and the main traveling body has An auxiliary traveling body is supported so that it can be reciprocally driven along a direction orthogonal to the traveling direction, and a plurality of grain stirring augers are suspended in a suspended state on the auxiliary traveling body while being arranged side by side in the traveling direction. Each of the plurality of electric motors that are supported and drive the plurality of grain stirring augers separately are arranged above the grain stirring auger to be driven and have their output shafts driven. For stirring grain A state directly connected to the upper portion of the over gas, characterized in that it is supported by the auxiliary traveling body.

That is, since the output shaft of the electric motor and the upper portion of the grain stirring auger are directly connected to each other, the electric motor can be driven even if the grain stirring auger is driven to rotate for a long time. Unlike the conventional chain-type transmission mechanism, the output shaft and grain auger auger connection state does not change, and maintenance such as adjusting the tension of the chain is a cumbersome task at high places. It is not necessary to perform the work frequently every short period, and the frequency of such maintenance work can be reduced.

In addition, when the output shaft of the electric motor and the grain stirring auger are interlocked and coupled, for example, it is conceivable to employ a gear mesh type transmission mechanism instead of the conventional chain type transmission mechanism. However, even in such a gear meshing type transmission mechanism, if the rotation drive of the grain stirring auger is performed for a long time, the gears interlocking with each other may be worn, so it is necessary to regularly lubricate to prevent wear. For example, the number of maintenance work increases, but in contrast, if the output shaft of the electric motor is directly connected to the grain stirring auger, chain elongation and wear at the gear contact portion will occur. Since there is no need to perform maintenance work for inspection over a long period of time, the number of maintenance work can be reduced. That.

Therefore, according to the first aspect of the present invention, it is possible to reduce the frequency of performing maintenance work for the transmission mechanism between the electric motor and the grain auger, and the grain is stored in the storage space and stirred. The maintenance work on the transmission mechanism between the electric motor and the grain stirring auger reduces the frequency at which the stirring action on the grain cannot be properly performed when the treatment is required, and the maintenance work on the stored grain is reduced. It has become possible to provide a grain agitation device in a grain storage facility that enables appropriate agitation processing.

The grain agitator in the grain storage facility according to a second aspect of the present invention is a storage space for storing grains for drying or storage, which has a rectangular shape in a plan view and is located in an upper portion of the storage space. A main traveling body that is installed across a pair of opposing side portions and is reciprocally driven along the longitudinal direction of the pair of side portions is provided, and the main traveling body has a direction orthogonal to the traveling direction. Auxiliary traveling bodies are supported so as to be reciprocally driven along, and a plurality of grain stirring augers are suspended and supported on the auxiliary traveling bodies in a state of being arranged at intervals in the traveling direction. And the electric motor for driving the traveling wheels of the auxiliary traveling body is arranged side by side with respect to the traveling wheels to be driven, and the output shaft thereof is directly connected to the traveling wheels to be driven. Provided on the body And wherein the Rukoto.

That is, since the output shaft of the electric motor and the traveling wheels of the auxiliary traveling body are directly connected to each other, the traveling wheels of the auxiliary traveling body can be rotationally driven for a long time. The connection state between the output shaft of the electric motor and the traveling wheels of the auxiliary traveling body does not change, and unlike the conventional chain type transmission mechanism, the tension of the chain, which is a troublesome work at high places, It is not necessary to frequently perform maintenance work such as adjustment every short period, and the frequency of such maintenance work can be reduced.

In addition, when the output shaft of the electric motor and the grain stirring auger are interlocked and coupled, for example, it is conceivable to employ a gear meshing type transmission mechanism instead of the conventional chain type transmission mechanism. However, even in such a gear meshing type transmission mechanism, if the rotation drive of the grain stirring auger is performed for a long time, the gears interlocking with the mesh may be worn, and it is necessary to regularly lubricate to prevent wear. However, if the configuration is such that the output shaft of the electric motor is directly connected to the traveling wheels of the auxiliary traveling body, chain extension and wear at the gear contact parts, etc. Since it does not occur, 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 second aspect of the present invention, it is possible to reduce the frequency of performing maintenance work on the transmission mechanism between the electric motor and the traveling wheels of the auxiliary traveling body,
When grains are stored in the storage space and stirring processing is required, the frequency with which the stirring action on the grains cannot be properly performed due to maintenance work on the transmission mechanism between the electric motor and the traveling wheels of the auxiliary traveling body can be performed. It has become possible to provide a grain agitation device in a grain storage facility that can make the agitation process for the stored grains appropriate by making it low.

In the grain agitating device of the grain storage facility according to a third aspect of the invention, the grain stirring device in a plan view has a rectangular shape in a plan view for storing grains for drying or storage, and the storage space is opposed to the upper part of the storage space in a plan view. A main traveling body that is equipped in a state of extending over a pair of side portions and is reciprocally driven along the longitudinal direction of the pair of side portions is provided, and the main traveling body is provided in a direction orthogonal to the traveling direction. An auxiliary traveling body is supported along a reciprocating drive freely along the auxiliary traveling body, and a plurality of grain stirring augers suspended and supported in a hanging state in a state of being arranged at intervals in the traveling direction on the auxiliary traveling body, Each of the plurality of grain stirring augers is suspended and supported by the auxiliary traveling body so as to be free to move in the traveling direction of the main traveling body, and
It is characterized in that the main traveling body is connected by a connecting body so as to freely move in the traveling direction of the main traveling body.

That is, since each of the plurality of grain stirring augers is suspended and supported by the auxiliary traveling body so as to be free to move in the traveling direction of the main traveling body, when the main traveling body is driven and driven,
Even if the grain agitating auger is subject to movement resistance due to grain and may cause a delay in movement, it is possible to prevent damage to the grain agitating auger due to excessive force due to the drive traveling of the main traveling body. .

Since each of the plurality of grain stirring augers is connected by a connecting body so as to move in the traveling direction of the main traveling body in an integrated state, any one of the plurality of grain stirring augers is used. However, even if the grain is moving along the side wall of the storage space, it is possible to appropriately perform the stirring process on the stored grain. To add a further explanation, for example, one of the plurality of grain agitating augers is moving along near the side wall of the storage space, and the other grain agitating auger of the storage space distant from the side wall. When the main traveling body is traveling along the side wall in the state of being located on the inner side, as described above, the grain stirring auger located near the side wall is located on the inner side. The movement resistance to the grain becomes larger than that of the grain auger for agitation, and due to such a large movement resistance, the main traveling body tries to move and retreat to a large extent, but at this time, Since the movement resistance of the grain stirring auger located on the inner side is not so large as compared with the grain stirring auger located near the side wall, the force acting to largely retreat along with the traveling of the main traveling body is small.

Since the plurality of grain agitating augers are connected by a connecting body so as to float integrally in the traveling direction of the main traveling body, the grain agitating augers located near the side walls are connected to the main traveling body. However, the grain augers for grain agitation located on the inner side restrain each other so as to suppress such a backward displacement. It is possible to prevent the agitating auger located nearby from being largely displaced backward, and it is possible to appropriately perform the agitation process on the stored grains.

Further, for example, even when each of the plurality of grain agitating augers is in a state of moving and retracting with respect to the traveling of the main traveling body, each of the plurality of grain agitating augers is connected to the connecting body. Since they are connected together, the restoring force toward the vertical posture becomes large, and it becomes possible to return to the original posture as quickly as possible, and it becomes possible to properly perform the stirring process for the stored grains. .

As a result, in order to prevent the grain stirring auger from being damaged by being subjected to an excessive force due to the driving traveling of the main traveling body, the grain stirring auger is provided so as to be freely movable, while such grain stirring is carried out. To eliminate the conventional disadvantage that the agitation process for stored grains cannot be performed properly due to the free structure of the operating auger, and to perform the agitation process for stored grains properly. It has become possible to provide a grain agitator in a grain storage facility that enables the above.

According to a fourth aspect of the present invention, in the grain agitating device in the grain storage facility according to the third aspect, whether or not the amount of free movement of the grain auger from the vertical posture in the traveling direction of the main traveling body exceeds a set amount. Based on the detection information of the floating detection means and the detection information of the floating detection means, when the amount of the floating exceeds the set amount, the drive running of the main traveling body is stopped, and the amount of the floating is less than the set amount. And a movement operation means for restarting the drive traveling of the main traveling body when the vehicle returns to the state.

That is, it is detected by the floating detecting means whether or not the floating amount along the traveling direction of the main traveling body exceeds the set amount from the vertical posture of the grain stirring auger. The movement operating means, a movement delay occurs due to the movement resistance of the grain stirring auger as the main traveling body is driven, based on the detection information of the floating detection means,
When it is determined that the floating amount exceeds the set amount, 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 toward 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 restarted. .

For example, if the main traveling body is not stopped, the grain stirring auger will move largely and excessive force will be applied, or the stirring process for the stored grains cannot be performed properly. However, according to the above configuration, such an inconvenience can be avoided in advance.

Even if the traveling of the main traveling body is stopped in order to avoid the above-mentioned inconvenience, each of the plurality of grain stirring augers is allowed to move integrally in the traveling direction of the main traveling body. Since the grain stirring auger is connected with the connecting body, the restoring force of the grain stirring auger toward the vertical posture becomes large, and the traveling stop time until the main traveling body starts traveling after returning to the original posture is reduced. By making the grain as short as possible, it becomes possible to properly perform the stirring process on the stored grains, and a suitable means for carrying out claim 3 can be obtained.

Auxiliary traveling body 102 and auger 103 for stirring each grain
Can be moved integrally along the Y direction,
By stopping the driving of the electric motor for traveling and driving the electric motor M2 for lateral movement, each of the auxiliary traveling body 102 and each grain stirring auger 103 can be moved along the X direction. , And as shown in FIG.

A control device H for controlling the operation is provided so that the can be stirred.

That is, in the initial state of the stirring work, each grain stirring auger 103 is located at a corner (standby position) of the target area, and each stirring motor is driven by the electric motor M3 for stirring each grain. While stirring at 103, an electric motor for traveling is driven to drive the main traveling body 101 to move each grain stirring auger 103 in the Y direction. When the limit switch SW1 detects that the vehicle has traveled to the movement limit, the electric motor M2 for lateral movement is driven for a set time to move the auxiliary traveling body 102, that is, each grain stirring auger 103 by a predetermined pitch in the X direction.

When the main traveling body 101 is driven by driving the electric motor M1 for traveling to move the grain stirring augers 103 in the Y direction, as shown by the phantom lines in FIG. Each grain stirring auger 103 may retreat and rock and tilt due to the movement resistance received from the tilting auger 103. It is detected based on the detection information of the tilt sensor SE that the tilt amount exceeds a set value. Then, the control device H stops driving the electric motor M1 for traveling at that time, and when the inclination amount of each grain stirring auger 103 returns to a value smaller than the set value, the electric motor for traveling is driven. The configuration is such that the driving of the motor M1 is restarted. At this time, as described above, since each grain auger 103 is connected by the connecting body 132 so as to integrally swing in the traveling direction of the main traveling body 101, the auger 103 for vertical orientation can be used. The restoring force increases, and it returns as quickly as possible until the tilt amount becomes a value smaller than the set value. Therefore,
Using the control device H, based on the detection information of the tilt sensor SE, the drive traveling of the main traveling body 101 is stopped when the amount of free movement exceeds a set amount, and the swing amount is returned to a state smaller than the set amount. Then, the moving operation means for restarting the drive traveling of the main traveling body is configured.
