Description

Technical Field

[0001] The utility model relates to the field of granary rainproof caps, in particular to a rainproof cap for a ventilating opening on a granary top. Background Art

[0002] The main function of the rain cap on the vent on the top of the granary is to prevent rain, snow, dust, etc. from entering the granary, while allowing air circulation to maintain air flow and temperature control in the granary. Since the rain cap is often exposed to the outdoors, it is necessary to choose corrosion-resistant and weather-resistant materials such as stainless steel, aluminum alloy or weather-resistant plastic.

[0003] Existing granary rain caps are generally hollow hemispherical in shape. When drying grain, the rain cap is generally opened to speed up ventilation. The upper end of the existing rain cap is closed. If the rain cap is directly moved from the upper end of the granary, the size of the rain cap increases and it cannot be opened immediately. On sunny days, the contact area between sunlight and grain is small, resulting in slower grain drying efficiency. Utility Model Content

[0004] The main purpose of the utility model is to provide a rainproof cap for the vent on the top of the granary, which can effectively solve the technical problem that the upper end of the existing rainproof cap in the background technology is in a closed state. If the rainproof cap is directly moved from the upper end of the granary, the size of the rainproof cap will increase and it will not be able to be opened immediately. On sunny days, the contact area between sunlight and grain is small, resulting in slow grain drying efficiency.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] As a further solution of the present invention, a wind source guide structure is provided on the upper end of the cross plate, and the wind source guide structure includes a fixed seat fixedly provided on the upper end of the cross plate, a wind guide plate is fixedly installed at the center of the upper end of the fixed seat, and four guide grooves are opened inside the fixed seat.

[0008] As a further solution of the present invention, four inclined ducts are fixedly provided inside the air guide plate.

[0009] As a further solution of the present invention, the shape of the air guide plate is H-shaped, and a rectangular ventilation slot is opened in the middle of the air guide plate.

[0011] As a further solution of the present invention, a connecting piece is fixedly provided at the middle part of the lower end of the cross plate.

[0012] As a further solution of the present invention, the motor output end is fixedly connected to a circular plate, and two screws are fixedly provided at the lower end of the circular plate. A through hole is provided at the upper end of the inner plate located at the lower end of the two screws, and a nut is provided at the output end of the screw through the outer wall of the through hole.

[0013] The beneficial effects of the utility model are as follows:

[0014] By setting up a drying structure, when the upper end of the granary needs to be ventilated and dried, the inner plate can be rotated by starting the motor, which can realize the quick opening of the cap, so that sunlight can shine on the surface of the grain, reducing the difficulty of opening the cap;

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-5 As shown, a rainproof cap for the vent on the top of a granary comprises a cap body 1, a fixing ring 2 is fixedly provided at the lower end of the cap body 1, a cross plate 3 is fixedly provided on the inner wall of the fixing ring 2, a drying structure 4 is installed on the upper end of the cap body 1, and the drying structure 4 comprises a motor 5 fixedly installed on the upper end of the cap body 1, the output end of the motor 5 passes through the cap body 1 and is fixedly connected to an inner plate 6, a sealing gasket 7 is installed on the upper end of the inner plate 6, a drying groove 8 is provided at the front and rear ends of the cap body 1, the upper end of the sealing gasket 7 is combined with the inner wall of the cap body 1, and sealing strips 9 are fixedly provided on both sides of the lower end of the inner plate 6, and the lower end of the sealing strip 9 is in contact with the upper end surface of the fixing ring 2.

[0024] In this embodiment, a wind source guide structure 10 is provided at the upper end of the cross plate 3. The wind source guide structure 10 includes a fixed seat 11 fixedly provided at the upper end of the cross plate 3. A wind guide plate 12 is fixedly installed at the center of the upper end of the fixed seat 11. Four guide grooves 13 are opened inside the fixed seat 11.

[0025] The fixed seat 11 is used to install the wind guide plate 12, which is used to change the flow direction of the wind source to achieve diversion. The guide groove 13 facilitates the wind source to pass through the fixed seat 11 to dry the grain.

[0026] In this embodiment, four inclined ducts 14 are fixedly disposed inside the air guide plate 12 .

[0027] The inclined duct 14 is used to guide the wind source to the grain surface in a larger range, thereby accelerating the contact area between the grain and the wind source.

[0028] In this embodiment, the air guide plate 12 is H-shaped, and a rectangular ventilation slot is defined in the middle of the air guide plate 12 .

[0029] The H-shaped air guide plate 12 reduces the spread of wind from both sides of the air guide plate 12 .

[0030] In this embodiment, four mounting blocks 15 are fixedly provided in an annular shape on the outer wall of the fixing seat 11 . A limiting block 16 is provided on one side of the mounting block 15 away from the fixing seat 11 . The limiting block 16 is fixedly connected to the upper end of the cross plate 3 .

[0031] The four mounting blocks 15 enter into the four limiting blocks 16 to limit the fixing seat 11 .

[0032] In this embodiment, a connecting piece 17 is fixedly provided at the middle portion of the lower end of the cross plate 3 .

[0033] The connecting piece 17 is used to connect the cap body 1 to other objects.

[0034] In this embodiment, the output end of the motor 5 is fixedly connected to a circular plate 18, and two screws 19 are fixedly provided at the lower end of the circular plate 18. A through hole 20 is provided at the upper end of the inner plate 6 located at the lower end of the two screws 19, and a nut is provided on the outer wall of the through hole 20 through the output end of the screw 19.

[0035] The circular plate 18 is used to set the screw rods 19. The two screw rods 19 pass through the through holes 20 and cooperate with the nuts to be more firmly fixed to the hemispherical inner plate 6.

[0036] It should be noted that the utility model is a rainproof cap for the ventilation opening on the top of a granary. When the cap body 1 needs to be opened to dry the grain at the lower end, the motor 5 is started, so that the motor 5 drives the circular plate 18 to rotate, and the circular plate 18 drives the inner plate 6 to rotate, so that the sealing gasket 7 is rotated in contact with the inner wall of the cap body 1, thereby opening the sealing gasket 7, reducing the difficulty of the operator, and at the same time increasing the contact between sunlight and grain, so that the grain is better irradiated and dried;

[0037] When the wind source passes through the drying trough 8, part of the wind source contacts the front end of the wind guide plate 12, the wind source is blocked, and is diverted to the inside of the fixed seat 11. The wind source blows vertically, part of the wind source passes through the guide groove 13 and contacts the grain, part of the wind source enters the inclined conduit 14, and is ejected from the lower end of the inclined conduit 14 to dry the grain, and the other part of the wind source contacts the inner wall of the cap body 1 and is diverted to the lower end to dry the grain on the inner wall of the granary.

[0038] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
