[Industrial applications]

 This invention relates to a grain dryer.

[0002]

[Prior Art]

 Conventionally, the lower part of the left and right sides of the upper part of the grain storage chamber that stores the grains is a ventilation net plate, and the upper part of the ventilation chamber plate made of plate material is formed into a mountain shape. Two lozenge-shaped air-blowing chambers are formed by overlapping with each other, and a ventilation net plate is formed in the center between the air-blowing chambers in a triangular shape, and a triangular shape is formed by the ventilation net plates on the left and right outer sides. -Like left and right ventilation chambers are provided, and four grain drying chambers are provided between the respective ventilation chambers and the central ventilation chamber and the left and right ventilation chambers to dry the grain while allowing it to dry. A grain drier was installed on the lower side of the room to collect the fallen grains, and it was a grain dryer.

[0003]

[Problems to be solved by the device]

 Grains stored in the grain storage chamber of the grain dryer are circulated by feeding out from the storage chamber into the four-row grain drying chamber, while hot air is blown from the ventilation nets in each ventilation chamber to each drying chamber. The air flowing through the central ventilation chamber and the left and right ventilation chambers is exhausted to the outside of the machine, so that the grains flowing down in each drying chamber are exposed to this hot air and dried. When the moisture content of the grain reaches the finishing target moisture content, the dryer is stopped to stop the drying of the grain.

During this drying operation, if the moisture content of the dried grains is high, the upper end portions of the left and right air-blowing chamber plates that form the rhombus-shaped air-blowing chamber are formed in a mountain shape. Due to the configuration in which the air-blowing chamber is formed by stacking the chevron portions, the air-blowing chamber plate may be deformed by the pressure of the grains flowing down the drying chamber, which causes the grains flowing down the drying chamber. Poor grain flow occurs, and the width of the drying chambers on the left and right sides of the air blowing chamber is different. Therefore, the density of grains in the drying chamber is different, and the drying chamber flows down. The flowing speed of the grain is different between the drying chambers on the left and right, which may cause the unevenness of drying of the grain, which is to be solved.

[0005]

[Means for Solving the Problems]

 In this invention, lower lobes on both left and right sides are formed on the lower side of the grain storage chamber 1 on the upper side, and lozenge-shaped blowing chambers 5 and 5 are formed on the upper side by the ventilation chamber plates 4 and 4 made of the plate material 3. U-shaped reinforcing members 6 and 6 that are in a butted state from the left and right sides are provided at the upper ends of the plate members 3 and 3 of the blower plates 4 and a mountain-shaped match is made in a stacked state above the blower chamber 5. In addition to providing the member 7, a triangular central exhaust chamber 9 formed by a ventilation net plate 8 is formed in the central portion between the ventilation chambers 4 and 4, and a triangular shape formed by a ventilation net plate 10 is formed on both the left and right outer sides. Left and right air exhaust chambers 11 and 12 are provided, and grain drying is performed by flowing down the grains between the air blow chambers 5 and 5, the central air exhaust chamber 9, and the left and right air exhaust chambers 11 and 12. The grain dryer is configured such that four chambers 13 are provided, and a grain collecting trough 14 for collecting fallen grains is connected to the lower side of the drying chamber 13.

[0006]

[Function of the device]

 The grains stored in the grain storage chamber 1 of the grain dryer are fed from the storage chamber 1 into the four grain drying chambers 13 and flow down to be collected and circulated in the grain collecting trough 14. , Hot air passes from each ventilation net plate 2 of each ventilation chamber 5 to each drying chamber 13 and then to the outside of the machine through each central ventilation chamber 9 and each ventilation net plate 10 of the left and right ventilation chambers 11 and 12. By doing so, the grains flowing down in each of the drying chambers 13 are exposed to the hot air and dried, and when the moisture content of the grain reaches the finishing target moisture, the drier is stopped to remove the grain. Drying is stopped.

During this drying operation, even if the moisture content of the dried grain is high, the upper ends of the plate members 3, 3 on the upper and lower sides of the blower chamber plates 4, 4 forming the blower chamber 5 Reinforcing members 6 and 6 are provided in the section, and the blasting chamber plates 4 and 4 are not deformed by the pressure of the grain because the reinforcing members 6 and 6 are in a butt state, and the blasting is not performed. Since the mountain-shaped mating members 7 are provided in a stacked state on the upper side of the chamber plates 4 and 4, the blower chamber plates 4 and 4 are further reinforced and are not deformed. Further, by setting the widths of the drying chambers 13 on both the left and right sides of the blower chamber 5 to be substantially the same, the pressures of the grains in the respective drying chambers 13 and 13 are substantially the same, and the flow-down velocity of the grains is also the same. It is dried at almost the same flow rate.

[0008]

[Effect of the device]

 According to this invention, since the reinforcing members 6 and 6 are provided in abutting relation to the upper end portions of the plate members 3 and 3 above the blower chamber plates 4 and 4 forming the blower chamber 5, the blower chamber plates 4 and 4 are Since it was not reinforced and deformed, grain flow failure did not occur, and the grain flow rate could be made almost the same in the left and right grain drying chambers 13.
