Description

Technical Field

[0001] The utility model is applied to the field of crop storage, and particularly relates to a moisture-proof storage device for crops. Background Art

[0002] Crops stored in humid environments are prone to mold growth. This mold growth can cause crops to deteriorate and rot, reducing their quality and nutritional value. For example, grains stored in humid environments may produce aflatoxin, a potent carcinogen that poses a serious health hazard. Furthermore, high humidity conditions create favorable conditions for the growth of pests and diseases. Many pests and pathogens multiply rapidly in humid environments, causing serious damage to crops. For example, rice is susceptible to diseases such as rice blast and sheath blight in high humidity, which can also increase pest populations, affecting rice yield and quality. Therefore, crops need to be promptly treated to prevent moisture. This can reduce the occurrence of pests and diseases and lower the cost of prevention and control.

[0003] Currently, when protecting crops from moisture, it's common to select a suitable storage location. Warehouses or sites for storing crops should be located in high, dry, and well-ventilated areas. Warehouses should also have good ventilation facilities, such as windows and vents, to facilitate air circulation and reduce humidity. Existing warehouses typically stack crops directly inside, using air inlets and outlets on the walls to provide ventilation. This method only protects the surface of the crops from moisture, while crops stacked below lack adequate ventilation, which can easily cause moisture and mold on the bottom. This not only increases crop losses but can also impact the overall inventory. Summary of the Invention

[0004] The purpose of the utility model is to provide a moisture-proof storage device for crops.

[0005] The above purpose is achieved through the following technical solutions:

[0006] A moisture-proof storage device for crops, comprising a linear ventilation duct 1 and a four-way butt-jointed ventilation duct 2. The ends of the linear ventilation duct are fixedly connected to the ends of the four-way butt-jointed ventilation duct, so that the four linear ventilation ducts and the four-way butt-jointed ventilation duct form a cross-shaped structure. The linear ventilation duct and the four-way butt-jointed ventilation duct have the same height. A group of ventilation holes 3 are evenly opened on both sides of the linear ventilation duct.

[0007] A set of straight ventilation ducts are laid horizontally and vertically on the floor of the warehouse through four-way docking ventilation ducts. An air duct 4 is opened on the warehouse wall on either side of the warehouse, and a fan 5 is installed in the air duct. The fan is fixedly connected to the straight ventilation duct at the entrance of the warehouse.

[0008] In the moisture-proof storage device for crops, the ends of the linear ventilation duct and the four-way butt-joint ventilation duct are respectively connected with mounting plates 6, which have circular holes. Bolt assemblies 7 respectively pass through the mounting plates of the linear ventilation duct and the four-way butt-joint ventilation duct to fix the linear ventilation duct and the four-way butt-joint ventilation duct in connection.

[0009] In the moisture-proof storage device for crops, the cross section of the linear ventilation duct is U-shaped, and ribs 8 of a cross structure are installed between the two longitudinal plates of the linear ventilation duct.

[0010] In the moisture-proof storage device for crops, support pads 9 are connected below the longitudinal plates on both sides of the linear ventilation duct.

[0011] In the moisture-proof storage device for crops, the top of the linear ventilation duct is a closed structure, and filter screens 10 are connected to the inner walls of the longitudinal plates on both sides of the linear ventilation duct.

[0012] The beneficial effects achieved by the utility model are:

[0026] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention. Example 1

[0027] A moisture-proof storage device for crops, comprising a linear ventilation duct 1 and a four-way butt-jointed ventilation duct 2. The ends of the linear ventilation duct are fixedly connected to the ends of the four-way butt-jointed ventilation duct, so that the four linear ventilation ducts and the four-way butt-jointed ventilation duct form a cross-shaped structure. The linear ventilation duct and the four-way butt-jointed ventilation duct have the same height. A group of ventilation holes 3 are evenly opened on both sides of the linear ventilation duct.

[0028] A set of straight ventilation ducts are laid horizontally and vertically on the floor of the warehouse through four-way docking ventilation ducts. An air duct 4 is opened on the warehouse wall on either side of the warehouse, and a fan 5 is installed in the air duct. The fan is fixedly connected to the straight ventilation duct at the entrance of the warehouse.

[0029] The straight ventilation duct 1 and the four-way connecting ventilation duct 2 are made of metal. When the fan is working, the air outside the warehouse is sent into the straight ventilation duct 1 and the four-way connecting ventilation duct. After the straight ventilation duct 1 and the four-way connecting ventilation duct 2 are connected in the warehouse, a horizontal and vertical vertical cross structure is formed, and the air outside the warehouse is sent into the ventilation duct composed of the straight ventilation duct 1 and the four-way connecting ventilation duct 2. The air is discharged from the ventilation holes on the longitudinal plates on both sides of the straight ventilation duct, thereby ventilating a group of crops on both sides of the straight ventilation duct. Example 2

[0030] According to the moisture-proof storage device for crops described in embodiment 1, the ends of the linear ventilation duct and the four-way butt-joint ventilation duct are respectively connected to a mounting plate 6, which has a circular hole. The bolt assembly 7 passes through the mounting plates of the linear ventilation duct and the four-way butt-joint ventilation duct respectively to fix the linear ventilation duct and the four-way butt-joint ventilation duct in connection.

[0031] The mounting plate is a rectangular metal plate structure, and the mounting plate structures on the straight ventilation duct 1 and the four-way docking ventilation duct 2 are the same. By arranging mounting plates on the straight ventilation duct 1 and the four-way docking ventilation duct 2, a group of straight ventilation ducts 1 and a group of four-way docking ventilation ducts 2 can be finished and connected to form an integrated structure. Example 3

[0032] According to the moisture-proof storage device for crops described in Example 1 or 2, the cross-section of the linear ventilation duct is U-shaped, and ribs 8 with a cross structure are installed between two longitudinal plates of the linear ventilation duct.

[0033] The ribs are fixed between the two longitudinal plates of the linear ventilation duct by welding. The strength of the linear ventilation duct can be increased by arranging the ribs on the linear ventilation duct. Example 4

[0034] According to the moisture-proof storage device for crops described in embodiment 1, 2 or 3, support pads 9 are connected below the longitudinal plates on both sides of the linear ventilation duct.

[0035] The support pad adopts a rectangular metal plate structure, and is fixed to the longitudinal plates on both sides of the linear ventilation duct by welding, so that the longitudinal plates of the linear ventilation duct and the support pad are vertically connected as one. By setting the support pad, the stability of the linear ventilation duct can be increased. Example 5

[0036] According to the moisture-proof storage device for crops described in Example 1, 2, 3, or 4, the top of the linear ventilation duct is a closed structure, and filter screens 10 are connected to the inner walls of the longitudinal plates on both sides of the linear ventilation duct.

[0037] The wire mesh is specifically arranged on the inner side of the longitudinal plate of the linear ventilation duct. The filter wire mesh can be fixed by welding or bundling. The aperture of the filter wire mesh is smaller than the diameter of the ventilation holes on the linear ventilation duct, thereby preventing crops from entering the linear ventilation duct.

[0038] The ends of the straight ventilation ducts are fixed to the four directions of the four-way butt-jointed ventilation ducts by bolt assemblies, and a group of four-way butt-jointed ventilation ducts and a group of straight ventilation ducts are connected and arranged in the warehouse in turn. A duct is opened on one side of the warehouse, and a fan is installed at the duct. The air supply port of the fan is connected to one of the straight ventilation ducts at the end of the warehouse. When the fan is working, the air outside the warehouse is sent from the straight ventilation duct at the entrance to the four-way butt-jointed ventilation duct, and then the air is sent into the straight air ducts in other directions through the four-way butt-jointed ventilation duct. The air is discharged from the air outlet holes on the longitudinal plates on both sides of the straight ventilation duct to ventilate both sides of the crops and increase the ventilation area of the crop stack. At the same time, the top of the straight ventilation duct is a closed structure. The height of the straight ventilation duct and the four-way butt-jointed ventilation duct is higher than the height of the crop stack in the warehouse. Personnel can walk above the straight ventilation duct and the four-way butt-jointed ventilation duct, which is convenient for managing the crop stacks in different areas.
