Description

  The present invention relates to a grain dryer that is easy to store.

  Grain dryers are used only during certain harvest periods, such as in the fall of the year, and after use, the remaining rice and dust collected in the machine are blown away and cleaned, and then stored in a barn or other warehouse. . However, a conventional grain dryer manufactured using a material such as a steel plate is very inconvenient to move during storage because of its large volume and heavy weight. Then, what is disclosed by patent document 1 is known as a lightweight grain dryer, without being bulky at the time of accommodation, for example. This includes a dryer body having a grain flow passage through which hot air for drying passes, a sheet body forming a closed space above the dryer body, and a detachably attached to the dryer body. It is the structure provided with the support frame which supports a sheet | seat body, and the grain raising apparatus which transfers the grain which flowed down the said grain flow path to the upper end part of the said closed space.

  As a result, the part that becomes the grain storage tank is made of a sheet body, and since the support frame is detachably attached to the dryer body, the sheet body and the support frame are removed from the dryer body during storage, Since the sheet body and the support frame can be separated and folded, the sheet body is not bulky and light in weight, which makes it very convenient for storage. If the amount of grain to be dried is small, the support frame can be moved up and down and fixed to the dryer body, and the connection tube of the cerealing device with a length corresponding to this can be used to dry the grain during use. There is also an advantage that the height of the machine can be lowered.

  However, in the grain dryer described in Patent Document 1, as a method of fixing the sheet body to the dryer body, the lower end portion of the sheet body is attached to a plurality of locking fittings attached around the upper end portion of the dryer body. It is done by fitting a plurality of holes provided in the surroundings, but the work of fitting the plurality of locking brackets and the plurality of holes is a cumbersome and cumbersome work of assembling and disassembling considering the alignment etc. there were. In particular, a machine with simplified assembly and disassembly work has been desired for the elderly.

  Moreover, in the said patent document 1, although a thrower is disclosed as a cerealing apparatus, when the amount of cerealing increases, there is a problem that a whipping height will reduce and capacity | capacitance will run short. A bucket lifting machine is mentioned as a mashing apparatus which does not have a problem in a conveyance amount and a cereal height. Therefore, as for the drive system of the transverse screw conveyor and the cerealing device, it is well known to connect the transverse screw conveyor and the sloter with a single drive shaft. It is not known to connect a conveyor and a bucket elevator with a single drive shaft. For example, Patent Document 2 discloses a supply device for a bucket elevator, but a motor for driving an elevator and a motor for driving a transverse screw conveyor are provided, and each is an independent drive mechanism. As a result, the manufacturing cost is high.
