DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0017] Please refer to​​Figures 1-3 The utility model provides a kind of eight open doors of convenient unloading, including unloading door 6, unloading door 6 is installed on the bottom circumferential outer wall of drying box 1, connecting seat 66 is welded on the circumferential inner wall of unloading door 6, connecting rod 65 is installed on connecting seat 66, one end of connecting rod 65 away from connecting seat 66 is provided with transmission arm 67, one end of transmission arm 67 away from connecting rod 65 is provided with connecting pin shaft 64, transmission arm 67 is connected with driven gear 63 by connecting pin shaft 64, bearing ring 632 is installed on the circumferential inner wall of driven gear 63, driven gear 63 is movably connected on the circumferential outer wall of center column 4 by bearing ring 632, driven gear 63 is installed with driving gear 62 on one side, the inside of drying box 1 is fixedly installed with speed reducer 61 by machine base, driven gear 63 is installed with travel switch 631.

[0018] Working principle: when actual use is carried out, malt is dried in the inside of drying box 1, needs to unload when, at this time, the external switch of speed reducer 61 is started, the output shaft of speed reducer 61 drives driving gear 62 to rotate, driving gear 62 drives driven gear 63 to rotate, and eight groups of unloading doors 6 are driven by eight groups of transmission arms 67 and connecting rods 65 on driven gear 63 to move, so that eight groups of unloading doors 6 are opened, and the unloading work of the material in the inside of drying box 1 is completed;Avoiding the blockage of unloading port, the situation that material is extruded at center column 4 occurs, the breakage rate of malt when discharging is reduced;Compared with common unloading center single door, when discharging, the material around the bottom center column 4 of drying box 1 will fall into the discharge hopper at the first time when unloading door 6 is opened, and the material in the center part can be output first, in the running process of combination machine, horizontal screw conveyor will continuously convey material to the center, once the unloading port is blocked for a long time, malt will be extruded at center column 4, leading to the increase of breakage rate of malt, the eight-door structure is adopted, the malt after drying is quickly unloaded, and the phenomenon that malt is extruded does not occur when unloading;Compared with common unloading center door, the unloading center door is driven by a single electric push rod actuator, and there is only one discharge door, so the space required for installation is large, and it is not conducive for maintenance workers to enter the unloading cylinder for equipment maintenance, the space inside the unloading center cylinder is compact, so the installation angle and position of push rod are very limited, but only a single speed reducer 61 is used in the eight-door structure to drive, which is convenient for installation and maintenance;After the drive is changed from electric push rod to speed reducer 61, the motor on speed reducer 61 also has the function of brake, but the torque transmitted by speed reducer 61 is larger than that of electric push rod, when the door is closed, when extruded by external material, the door can be sealed due to insufficient reaction force, and material scattering, and the unsealed door also leads to hot air short circuit and uneven drying.

[0019] As a preferable implementation, the drying box 1 is in a cylindrical shape, a support ring 2 is installed on the top of the drying box 1, the support ring 2 covers the top of the center column 4, and the surface of the drying box 1 is provided with two groups of manholes, and the surface of the two groups of manholes is provided with manhole cover plates 3.
