[0028] Embodiment 1

[0029] The technical scheme in the present application solves the problem of dust prevention of the discharge port, and the general idea is as follows:

[0030] In view of the problems in the prior art, the present application provides a discharge port dustproof structure for grain drying, which comprises

[0031] The drying box 1 is the whole of the drying equipment, the drying box 1 is provided with an inlet 2 above, the inlet 2 blows air through heating air flow, which can realize the dust removal effect of air pressure, the drying box 1 is provided with an outlet dustproof assembly 3 below the side edge, the outlet dustproof assembly 3 is provided with a sealing cover plate inside to shield dust,

[0032] As Figure 2As shown, the outlet dustproof component 3 includes a mounting plate 31, which is a square structural plate with a discharge port in the middle. A folding plate is provided at the upper end of the mounting plate 31, and a driving cylinder 32 is installed in the middle of the folding plate. An upper connecting plate 33 is installed at the lower end of the driving cylinder 32 via an output rod. A sealing plate 36 is provided in the middle of the lower part of the upper connecting plate 33. The sealing plate 36 blocks the discharge port in the drying chamber 1 to achieve dust prevention.

[0033] A lower support plate 35 is provided around the discharge port in the middle of the mounting plate 31. The lower support plate 35 has two sets of semi-circular ring structures. The upper half of the lower support plate 35 is a sliding groove, and the lower half of the lower support plate 35 is a lower retaining groove 38. The lower retaining groove 38 is a semi-circular ring receiving groove, and the upper half of it has a sliding groove in the middle of the mounting plate 31, through which the sealing plate 36 slides.

[0034] A lower sealing strip 39 is provided at the bottom below the sealing plate 36. The lower sealing strip 39 is an irregularly shaped baffle with a square upper part and a semi-circular lower part. The upper part of the lower sealing strip 39 is connected to the upper connecting plate 33, and the circular plate at the bottom of the lower sealing strip 39 is inserted into the lower slot 38 to achieve a good seal for the discharge port.

[0035] The lower support plate 35 has a snap-fit ​​protrusion on its outer side, which can be used to snap the subsequent discharge port pipeline, improving the ease of use.

[0036] A reinforcing rib 37 is provided in the lower center of the upper connecting plate 33. The reinforcing rib 37 increases the strength of the connection structure between the upper connecting plate 33 and the push rod in the drive cylinder 32, and prevents the side plate of the upper connecting plate 33 from being deformed due to insufficient strength.
