[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention makes it possible to easily carry out the work of loading the grain by using the work hopper or the pit according to the condition of the floor where the grain dryer is installed, and the power of the lower pulley shaft can be accurately adjusted to the lower position. The present invention relates to an elevator for a grain dryer, which is transmitted to a conveyor shaft so that a circulating fluidized drying operation can be performed.

[0002]

[Prior Art]

 Conventionally, in a grain dryer, the rotational power of the upper conveyor that is horizontally mounted on the top is transmitted to the lower conveyor that is horizontally mounted on the bottom via the belt of the elevator to rotate and rotate the grain. A grain dryer in which grain is loaded into a loaded hopper by which grain is loaded is described in, for example, Japanese Utility Model Publication No. 50-13813 prior to the filing of the present application.

[Problems to be solved by the device]

 By the way, when using the existing grain dryer installed on the floor as it is and performing the grain loading work in the pit newly excavated and molded on the floor surface, the elevator that was attached to the existing grain dryer cannot be used. Due to its short height, it is necessary to replace and install a long elevator that fits the height.Also, the power transmission of the lower conveyor is the same as the conventional belt transmission because the lower portion of the elevator is immersed in the pit. However, it is inevitable that a long transmission belt must be suspended between the drive pulley directly connected to the upper conveyor shaft and the driven pulley directly connected to the lower conveyor shaft to achieve power transmission. There is a problem in that the economic burden is unnecessarily large and the use of a long transmission belt causes many problems. The present invention has been made in view of the above problems of the conventional technology, and the purpose thereof is to provide a transmission mechanism without replacing an existing elevator with a long elevator. Connection It may be possible to easily separate the use of the grain loading work in the pit or the grain loading work by the loading hopper by simply attaching and removing the lifting body. It also aims to provide an elevator for grain dryers, which can be transmitted to the lower conveyor by using the power of belt rotation of the elevator and accurately achieve smooth circulation drying work.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the elevator for grain dryer in the present invention is formed by excavating and forming a pit on the floor surface directly below the elevator attached to one side of the grain dryer installed on the floor, and the lower end of the elevator described above is formed. At the same time, the connection hoisting cylinder immersed in the pit was detachably attached so that the inside communicated with each other, and the lower pulley shaft laid horizontally below the connection hoisting drum and the lower conveyor shaft laid horizontally below the dryer. Is transmitted through a transmission mechanism.

[0005]

[Action]

 When the grain is loaded into the grain dryer using the feed hopper, first, the elevator and the upper conveyor are rotated, and then the grain is fed into the feed hopper. Be stilted. Therefore, if the belt power is transmitted to the lower conveyor via an appropriate clutch device (not shown) to rotate it, and at the same time the feeding roll is rotated, the grains are exposed to dry hot air in the flow process and dried to some extent. It is then discharged into the unloading room, conveyed to the elevator by the lower conveyor, and then circulated and flowed to the grain dryer via the elevator and upper conveyor. Therefore, the grain is dried to a predetermined water content by a plurality of circulation drying operations.

By the way, in the drying operation as described above, in the case where a pit is formed by excavation on the floor surface directly below the elevator in order to load the grain carried by the truck etc. into the grain dryer as it is, the existing elevator is lifted. After removing the bottom wall with the attached, the auxiliary lifting cylinders of the same height are connected to the lower end so that the inside communicates with each other and the lower part sinks into the pit. Since the pulley is rotatably mounted on the storage shaft, replace the belt with a long belt.) By the way, since a pair of intermediate pulleys that are directly connected to each other are provided at both ends of the rotating shaft that passes through the lower part of the existing elevator, a transmission belt is connected to one of the intermediate pulleys and a driven pulley that is directly connected to the shaft of the lower conveyor. If the transmission belt is suspended around the drive pulley directly connected to the shaft of the lower pulley and the other intermediate pulley, the rotational power of the lower pulley is transmitted to the lower conveyor shaft via the aforementioned transmission mechanism. It is possible to accurately achieve power transmission from the lower part of the elevator to the lower conveyor even during the work of staking into the pit, and to circulate and dry the sewn grain in the same manner as described above.

【Example】

 In FIG. 1 and FIG. 2, reference numeral 1 denotes a well-known circulating type grain dryer capable of being dried by taking in hot dry air circulating in the course of falling grain, which is on the floor surface 2. At the bottom of the grain dryer 1 installed at the lower part of the grain dryer 1, a lower conveyor 4 for unloading the dried grain to a circulation elevator 3 attached to one side of the grain dryer 1 is rotatably placed horizontally. Has been done. A pit 5 having an appropriate depth is excavated and formed on the floor surface 2 directly below the elevator 3, and the upper surface is opened at the lower end of the elevator 3 whose bottom is opened and the lower portion is inside the pit 5. A connection lifting cylinder 6 having a length to be immersed in is detachably mounted and the insides thereof are connected to each other. A lower pulley 8 for suspending a lower end of a belt 7 equipped with a bucket is directly connected to a lower pulley shaft 9 which is horizontally mounted and is rotated by the rotation of the belt 7 in a lower part of the connecting lifting body 6. Is configured. Reference numeral 10 is a drive pulley directly connected to one end of the lower pulley shaft 9. Reference numeral 11 is a driven pulley directly connected to one end of the shaft 12 of the lower conveyor 4, and 13 is an intermediate rotary shaft that extends through the lower portion of the elevator 3 (that is, a position slightly lower than the lower conveyor shaft 12). Counter pulleys 14 and 15 are directly connected to the left and right ends of the intermediate rotary shaft 13, respectively. Reference numeral 16 denotes a transmission mechanism for transmitting the power of the drive pulley 10 to the driven pulley 11 to rotate the lower conveyor 4 by the rotation operation of the belt 7. The transmission mechanism 16 includes a drive pulley 10 and a counter pulley 15. It is composed of a transmission belt 17 suspended over the drive belt 11, and a transmission belt 18 suspended over the driven pulley 11 and the counter pulley 14. Reference numeral 19 is a pit tension hopper mounted on one side of the connecting lifting cylinder 6 such that the upper surface thereof is substantially flush with the floor surface 2. Reference numeral 20 denotes a clutch device for the transmission belt 18.

[Effect of the device]

 Since the present invention is configured as described above, it has the following effects. Even if the existing grain dryer installed on the floor is used as it is and the grain loading operation is performed using the newly excavated pit on the floor, the existing elevator is removed. Without lowering the lower conveyor shaft, it is possible to easily and mass-process and reduce facility costs by simply attaching a connecting lifting cylinder of a size that fits the pit depth to the lower end of the elevator. For the power transmission to the grain dryer without changing the conventional power transmission system, the power of the lower pulley shaft can be effectively used via the transmission mechanism to be carried out on the front side of the grain dryer to simplify the work operation.
