[0028] The following is in conjunction with the appendix Figs. 1-6 The present invention will be described in further detail below.
[0029] Example 1
[0030] Please see Figs. 1-6 This embodiment provides a technical solution for a hot air generating device for a dryer: a hot air generating device for a dryer includes a drying mechanism 2 and a mounting component 3. All equipment within the hot air generating device is connected to an external power source via power lines. A control panel is installed on the outer wall of the drying chamber 1. The hot air generating device is connected to the control panel via a data line. The drying mechanism 2 includes a mounting plate 201 disposed inside the drying chamber 1. A support plate 202 is bolted to the top surface of the mounting plate 201. Several sets of heating wires 203 are bolted to the top surface of the support plate 202. When the hot air generating device is started, the heating wires 203 are connected to the external power source. At this time, the heating wire 203 continues to heat up. A hot air outlet 4 is bolted to the top wall of the drying chamber 1. Multiple exhaust holes are provided on the outer wall of the drying chamber 1 to discharge hot air in an appropriate amount to reduce the temperature inside the drying chamber 1. The hot air outlet 4 is connected to the interior of the drying chamber 1. A fan 5 is bolted to the center of the outer wall of the drying chamber 1. The fan 5 is connected to the interior of the drying chamber 1. The fan 5 continuously exhausts air into the interior of the drying chamber 1. When it passes through the heating wire 203, it is converted into hot air. The hot air is discharged into the interior of the drying chamber 1 through the hot air outlet 4 to heat and dry the agricultural products placed above the hot air outlet 4.
[0031] Example 2
[0032] Please see Figs. 1-6The mounting component 3 is installed inside the drying chamber 1 and located below the drying mechanism 2. The mounting component 3 includes worm gears 301 rotatably connected to the two inner side walls of the drying chamber 1 via bearings. Several sets of worm gears 301 are provided on the two inner side walls of the drying chamber 1. The several sets of worm gears 301 are equidistantly distributed along the length direction of the drying chamber 1. A worm 302 is meshed above the worm gears 301. A worm 302 is meshed above each set of worm gears 301. The ends of each set of worm 302 are welded together to form an integrated structure. A threaded rod 303 is connected to the center position of the worm gear 301 away from the drying chamber 1 by screws.
[0033] A movable sleeve plate 304 is fitted around the outer circumference of the threaded rod 303. A threaded opening 307 is provided at the center of the movable sleeve plate 304. The end of the threaded rod 303 away from the worm gear 301 passes through the interior of the threaded opening 307 and is threadedly connected to the inner side of the threaded opening 307. Both ends of the movable sleeve plate 304 are bolted with mounting blocks 305. One end of the worm 302 is rotatably connected to the inner wall of the drying chamber 1 via a bearing, and the other end extends to the outside of the drying chamber 1 and is welded to the end of the control handle 306. Therefore, when the control handle 306 is gripped and rotated, the worm 302 is driven to rotate. The worm 302 engages with the worm gear 301, pushing the worm gear 301. The worm gear 301 drives the threaded rod 303 to rotate. A control handle 306 is provided on the outer wall of the drying oven 1 at a position corresponding to the worm 302. Rotating the control handle 306 causes the worm 302 to mesh with the worm gear 301, which is used to push the mounting block 305 to move laterally. When the threaded rod 303 rotates, it pushes the moving sleeve 304 to move laterally. When the moving sleeve 304 moves, it can push the mounting block 305 to be inserted into the limiting groove 102 and the mounting slot 204. By driving the control handle 306 to rotate or rotate in the opposite direction, the moving sleeve 304 can be moved toward or away from the limiting groove 102.
[0034] Example 3
[0035] Please see Figs. 1-6The drying mechanism 2 includes a mounting plate 201 disposed inside the drying chamber 1. The mounting plate 201 supports the heating wire 203 and the support plate 202, and is used to cooperate with the installation of the mounting component 3. The bottom end of the mounting plate 201 is inserted into the interior of the docking groove 101 and is in close contact with the inner side wall of the docking groove 101. A square docking block is provided on the bottom surface of the mounting plate 201 for limiting its insertion into the interior of the docking groove 101. Several sets of limiting grooves 102 are equidistantly provided inside the docking groove 101. The several sets of limiting grooves 102 communicate with the interior of the drying chamber 1. The side wall of the mounting plate 201 near the limiting grooves 102 is equidistantly provided with... Several sets of mounting slots 204, the limiting slots 102 and the mounting slots 204 are all the same in shape and size. The end of the mounting block 305 away from the moving sleeve 304 is inserted into the inside of the limiting slot 102 and the mounting slot 204 in sequence, and is in close contact with the inner side wall of the mounting slot 204. When the mounting block 305 is inserted into the inside of the limiting slot 102 and the mounting slot 204, the drying mechanism 2 can be fixedly installed. By rotating the control handle 306 to move the mounting block 305 away, until the mounting block 305 moves out of the inside of the limiting slot 102 and the mounting slot 204, the fixing of the drying mechanism 2 can be released.
[0036] Several sets of fixing slots 103 are provided on the outer wall of the drying chamber 1 near the control handle 306. The fixing slots 103 are equidistantly distributed around the control handle 306. A fixing rod 308 is inserted into the control handle 306. The end size of the fixing rod 308 is adapted to the fixing slot 103. When one end of the fixing rod 308 is inserted into the inside of a fixing slot 103, the control handle 306 can be fixed. When the fixing rod 308 is moved laterally outward, the fixing measures on the control handle 306 can be released, and the control handle 306 can be rotated again for installing or disassembling the drying mechanism 2. A baffle 104 is provided above the movable sleeve 304. The baffle 104 is connected to the inner wall of the drying chamber 1 by screws. The baffle 104 can separate the mounting part 3 from the drying mechanism 2, and play a certain role in dust prevention.
[0037] Working principle: First, move the fixed rod 308 outward laterally to release the limiting measures on the control handle 306. Then, hold the control handle 306 and start to rotate. At this time, the control handle 306 drives the worm 302 to rotate and mesh with the worm wheel 301, pushing the worm wheel 301 to rotate. The worm wheel 301 drives the threaded rod 303 to rotate.
[0038] Secondly, when the threaded rod 303 rotates, it pushes the movable sleeve 304 to move laterally. By rotating or rotating in the opposite direction, the movable sleeve 304 can be moved toward or away from the limiting groove 102. When the movable sleeve 304 is moved away from the limiting groove 102, the movable sleeve 304 drives the mounting block 305 to move out of the limiting groove 102.
[0039] Finally, when the mounting block 305 is completely removed from the inside of the limiting groove 102 and the mounting slot 204, the installation state of the mounting plate 201 is released. At this time, the inside of the drying chamber 1 is opened, and the mounting plate 201 is moved directly upward to complete the disassembly of the drying mechanism 2. The drying mechanism 2 is then repaired and inspected. When reinstallation is required, the above operation is repeated. The control handle 306 is rotated in the opposite direction to push the mounting block 305 into the inside of the limiting groove 102 and the mounting slot 204 in sequence, thus completing the work.
