The shape of the first air passing holes 2112122 is preferably a fish scale-shaped hole.

[0081] Further, the first hot air pipe assembly 2112121 includes two layers of first hot air pipe rows (not marked in the figure) arranged vertically, each of the first hot air pipe rows including a plurality of first hot air pipes uniformly spaced along the width direction of the drying machine body 10, and first stacking spaces 2112123 being formed between two adjacent first hot air pipes in the width direction.

[0082] Specifically, the design of the multi-layer hot air pipe row increases the contact area between the hot air and the grains, so that the hot air can more fully exchange heat with the grains, thereby improving the drying efficiency.

[0083] As a preferred embodiment, the material falling control assembly 211213 includes a horizontal drive cylinder 2112131 and a first cross baffle 2112132, the bin wall of the first drying bin 211211 is provided with a first through hole for the driving end of the horizontal drive cylinder 2112131 to penetrate, the width of the first cross baffle 2112132 is smaller than the width of the first drying bin 211211, the first cross baffle 2112132 and the driving end of the horizontal drive cylinder 2112131 are connected and move synchronously with the driving end of the horizontal drive cylinder 2112131, and the first cross baffle 2112132 is provided with a first material falling channel 2112133 corresponding to the first stacking space 2112123, wherein, when in the open position, the first material falling channel 2112133 and the first stacking space 2112123 are arranged opposite to each other, and when in the closed position, the first material falling channel 2112133 and the first stacking space 2112123 are arranged staggered, so as to make the grains stay in the first drying bin 211211.

[0084] Specifically, the blanking control assembly 211213 includes a horizontal drive cylinder 2112131 and a first cross barrier 2112132. The wall of the first drying bin 211211 is provided with a first through hole for the drive end of the horizontal drive cylinder 2112131 to penetrate. The horizontal drive cylinder 2112131 is connected with the first cross barrier 2112132 through the hole. The width of the first cross barrier 2112132 is smaller than the width of the first drying bin 211211, so that a blanking or blocking space can be left when the first cross barrier 2112132 moves. When the drive end of the horizontal drive cylinder 2112131 extends, the first cross barrier 2112132 is driven to move horizontally. The first cross barrier 2112132 is provided with a first blanking passage 2112133 corresponding to the first stacking space 2112123. The shape and position of the first blanking passage 2112133 match the first stacking space 2112123. When the first cross barrier 2112132 is in the open position, the first blanking passage 2112133 and the first stacking space 2112123 are arranged opposite to each other, and the grain can fall from the first drying bin 211211 into the lower buffer section 21122 through the passages. When the first cross barrier 2112132 is in the closed position, the first blanking passage 2112133 and the first stacking space 2112123 are arranged staggered, and the grain is blocked by the first cross barrier 2112132 and stays in the first drying bin 211211.

[0085] In the embodiment, the accurate movement of the first cross barrier 2112132 can be realized through the accurate control of the horizontal drive cylinder 2112131, so as to accurately control the blanking time of the grain.

[0086] As another preferred embodiment, the blanking control assembly 211213 further includes a dead zone blanking valve plate 2112134 hinged to the inner wall of the first drying bin 211211. The dead zone blanking valve plate 2112134 is located directly above the drive end of the horizontal drive cylinder 2112131. When in the open position, the dead zone blanking valve plate 2112134 is in a vertical state, so that the first blanking passage 2112133 and the first stacking space 2112123 are arranged opposite to each other. When in the closed position, the dead zone blanking valve plate 2112134 is in an inclined state, and the dead zone blanking valve plate 2112134 covers the corresponding first blanking passage 2112133, so that the grain stays in the first drying bin 211211.

[0087] In the embodiment, as Figure 8 and Figure 13As shown, in addition to the original horizontal drive cylinder 2112131 and the first horizontal baffle 2112132, the material discharge control component 211213 also adds a dead zone material discharge valve plate 2112134. The dead zone material discharge valve plate 2112134 is hinged to the inner wall of the first drying chamber 211211, allowing the dead zone material discharge valve plate 2112134 to switch between vertical and horizontal states. The dead zone material discharge valve plate 2112134 is located directly above the drive end of the horizontal drive cylinder 2112131, forming a complementary material discharge control mechanism with the first horizontal baffle 2112132.

[0088] like Figure 13 As shown, since the driving end of the horizontal drive cylinder 2112131 has a stroke, in order to adapt to this stroke, this embodiment reserves a certain gap between the left end of the first horizontal baffle 2112132 and the inner wall of the first drying chamber 211211. If this gap is not addressed, the grain will fall directly. Therefore, this embodiment designs a dead zone discharge valve plate 2112134. The dead zone discharge valve plate 2112134 works together with the first horizontal baffle 2112132 to more reliably control the grain discharge.

[0089] In a preferred embodiment, the cold air drying section 21130 includes a second drying chamber 21131, a cold air duct assembly 21132, and a discharge control assembly 21133. The cold air duct assembly 21132 includes a first cold air duct assembly 211321 disposed in the second drying chamber 21131 and a second cold air duct assembly 211323 connected to the outer wall of the dryer body 2110. A second air passage 211322 communicating with the second drying chamber 21131 is opened on the wall surface of the first cold air duct assembly 211321. The air inlet of the first cold air duct assembly 211321 and the air outlet of the second cold air duct assembly 211323 are connected. The air outlet of the first cold air duct assembly 211321 is connected to the outside of the dryer body 2110. The air inlet of the second cold air duct assembly 211323 is connected to an external cold air source.

[0090] The discharge control component 21133 has an open position and a closed position. When it is in the open position, the grain in the second drying chamber 21131 enters the discharge component 2130 through the grain outlet 21110. When it is in the closed position, the grain remains in the second drying chamber 21131.

[0091] Specifically, the cold air pipe assembly 21132 includes a first cold air pipe assembly 211321 arranged in the second drying bin 21131 and a second cold air pipe assembly 211323 connected to the outer wall of the drying machine body 2110. An external cold air source sends cold air into the second cold air pipe assembly 211323 through an air inlet of the second cold air pipe assembly 211323, and then the cold air passes through an air outlet of the second cold air pipe assembly 211323 and communicates with an air inlet of the first cold air pipe assembly 211321, so as to send the cold air into the first cold air pipe assembly 211321. Second air passing holes 211322 are arranged on the wall surface of the first cold air pipe assembly 211321. Cold air or normal temperature air enters the second drying bin 21131 through the second air passing holes 211322 to cool and dry the grain in the bin. The cooled cold air is discharged to the outside of the drying machine body 2110 through an air outlet of the first cold air pipe assembly 211321, completing a cold air circulation.

[0092] The discharge control assembly 21133 has an open position and a closed position, and is used to control the discharge of the grain in the second drying bin 21131. When the discharge control assembly 21133 is in the open position, the grain in the second drying bin 21131 can enter the discharge assembly 2130 through the grain outlet 21110 and then be discharged from the drying machine. When the discharge control assembly 21133 is in the closed position, the grain is blocked in the second drying bin 21131 and cannot be discharged through the grain outlet 21110.

[0093] Further, the first cold air pipe assembly 211321 includes a plurality of first cold air pipes arranged uniformly along the width direction of the drying machine body 2110. Adjacent two first cold air pipes along the width direction form a second stacking space 211324.

[0094] Specifically, the first cold air pipes are arranged uniformly along the width direction of the drying machine body 2110, which can ensure that the cold air is distributed more uniformly in the second drying bin 21131.

[0095] As a preferred embodiment, the discharge control assembly 21133 includes a driving mechanism 211331, a crank slider mechanism 211332, and a second cross baffle 211333. The crank slider mechanism 211332 is connected to the driving mechanism 211331. The second drying bin 21131 is provided with a second through hole matched with the crank slider mechanism 211332. The width of the second cross baffle 211333 is less than the width of the second drying bin 21131.

[0096] The second cross baffle 211333 is provided with a second discharging channel 211334 corresponding to the second stacking space 211324, the second cross baffle 211333 is connected with the crank slider mechanism 211332 and reciprocates in the transverse direction following the crank slider mechanism 211332, so as to control the communication width between the second discharging channel 211334 and the second stacking space 211324, and then adjust the discharging amount of grain.

[0097] Specifically, the driving mechanism 211331 drives the crank slider mechanism 211332 to make the second cross baffle 211333 reciprocate in the transverse direction, the width of the second cross baffle 211333 is smaller than the width of the second drying bin 21131, so that the second cross baffle 211333 can move in the transverse direction in the drying bin, and the second cross baffle 211333 is provided with a second discharging channel 211334 corresponding to the second stacking space 211324.

[0098] By controlling the moving position of the second cross baffle 211333, the communication width between the second discharging channel 211334 and the second stacking space 211324 can be adjusted, when the communication width increases, the discharging amount of grain increases, when the communication width decreases, the discharging amount of grain decreases, this adjustment mode can accurately control the discharging amount of grain according to actual needs.
