[0023] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0024] Existing grain hoppers consist of multiple flat plates connected sequentially along the circumference of the hopper. Any two adjacent plates are connected at an angle to form a corner. During installation, the angle between adjacent plates needs to be adjusted, which is difficult and prone to large installation errors at the corners, leading to gaps or bulges and potential grain leakage. To address these issues, this invention provides a grain hopper and a grain dryer.

[0025] Figure 1 This is a schematic diagram of the structure of the material collection hopper disclosed in this utility model; Figure 2 This is a side view of the material collection hopper disclosed in this utility model; Figure 3 yes Figure 2 Sectional view at point AA; Figure 4 This is a schematic diagram of the connection between the corner plate and the connecting plate of the hopper disclosed in this utility model.

[0026] See Figures 1 to 4This utility model proposes a material collection hopper, which includes multiple corner plates 1 arranged around the circumference of the hopper. The connecting sides of adjacent corner plates 1 are parallel and tightly connected. The parallel and tightly connected connecting sides of adjacent corner plates 1 enable connection of the material collection hopper, simplifying operation, avoiding connection at corners, and eliminating the need to adjust the connecting angle of the corner plates 1 during connection. This reduces installation errors at the corner plate connection, improves installation efficiency, and prevents gaps or protrusions at the connection, enhancing the sealing of the connection and preventing grain leakage. The multiple corner plates 1 connected around the circumference of the hopper result in a simple structure.

[0027] In some embodiments, the corner plate 1 is integrally formed. The integrally formed corner plate 1 can effectively improve the firmness of the corner plate 1 and ensure a smooth transition at the corner.

[0028] To improve the wear resistance of the corner plate 1, the corner plate 1 is made of wear-resistant steel. Wear-resistant steel can improve the wear resistance of the corner plate 1, thereby increasing the service life of the hopper.

[0029] To facilitate the installation and removal of multiple corner plates 1 of adjacent collection hoppers, the collection hopper also includes a connecting structure for tightly connecting two adjacent corner plates 1. The connecting structure enables the connection of multiple corner plates 1 to form a collection hopper, ensuring the stability and tightness of the connection; at the same time, the connecting structure allows for the removal of multiple corner plates 1, facilitating the handling of the collection hopper.

[0030] To ensure a tighter connection between the connecting sides of adjacent corner plates 1, the connecting side of one corner plate 1 overlaps with the connecting side of the adjacent corner plate 1. This overlap prevents gaps or protrusions at the connection point of the two corner plates 1, ensuring a tight fit and improving the sealing of the connection, thereby preventing grain leakage.

[0031] To achieve a detachable connection between two adjacent corner plates 1, the connection structure includes bolts 5, nuts 6, and corner flanges 3 located on both outer sides of the corner plates 1. Bolts 5 pass through the connection holes of the corner flanges 3 of the two adjacent corner plates 1 and are threadedly connected to the nuts 6. When the two adjacent corner plates 1 are arranged parallel and tightly fitted, the two adjacent corner flanges 3 are connected together by bolts 5 and nuts 6, thus achieving a detachable connection between the two corner plates 1. This improves the maintenance efficiency of the hopper, reduces the maintenance cost of the hopper, and facilitates the transportation of the hopper.

[0032] It should be noted that the above are examples of specific methods for detachable connection of two adjacent corner plates 1 as described in this utility model, and should not be construed as limiting the specific methods for detachable connection of two adjacent corner plates 1 as described in this utility model. Any structure that can achieve detachable connection of two adjacent corner plates 1 will fall within the protection scope of this utility model. For example, the connection structure includes a pin and corner flanges 3 disposed on both outer sides of the corner plate 1.

[0033] In some embodiments, the corner flange 3 is fixedly installed on the outside of the corner plate 1 by welding.

[0034] In some embodiments, the corner flange 3 is made of cold-rolled steel plate.

[0035] To improve the stability of the connection between two adjacent corner plates 1, when the two adjacent corner plates 1 are set in parallel, the two adjacent corner flanges 3 are tightly fitted together. This tight fit of the two adjacent corner flanges 3 prevents the two connected corner plates 1 from shifting position, ensuring the stability of the connection between the two corner plates 1.

[0036] In some embodiments, when the connecting side of one corner plate 1 overlaps the connecting side of the adjacent corner plate 1, the two adjacent corner flanges 3 fit tightly together.

[0037] To ensure that the corner flanges 3 of two adjacent corner plates 1 can fit tightly together, the corner flanges 3 are set perpendicular to the connecting side of the corner plates 1.

[0038] To ensure a secure connection between two adjacent corner flanges 3, each corner flange 3 has a length extending along the connection side and multiple connection holes, with each connection hole corresponding to the length of an adjacent corner flange 3. The extension of the corner flange 3 along the connection side and the presence of multiple connection holes make the connection between the two adjacent corner flanges 3 more robust. The one-to-one correspondence of the connection holes between two adjacent corner flanges 3 allows bolts 5 to pass through the connection holes, thus connecting the two adjacent corner flanges 3.

[0039] In some embodiments, multiple corner flanges 3 are provided, each corner flange 3 is provided with a connection hole, and the multiple corner flanges 3 are distributed at intervals along the length direction of the connection side, and the multiple corner flanges 3 of two adjacent corner plates 1 are provided in a one-to-one correspondence. The one-to-one correspondence of the multiple corner flanges 3 of two adjacent corner plates 1 makes the connection between adjacent corner plates 1 tighter and ensures the stability of the connection of corner plates 1.

[0040] In some embodiments, the connecting sides of adjacent corner flanges 3 are fixedly connected by welding.

[0041] In some embodiments, see Figure 1The hopper also includes a connecting plate 2, which connects two adjacent corner plates 1. The connecting plate 2 is parallel to and tightly fitted to the connecting sides of the two adjacent corner plates 1 on both sides of the circumference of the hopper. The connecting plate 2 connects the two adjacent corner plates 1, thereby ensuring the connection stability of the hopper. At the same time, the setting of the connecting plate 2 increases the size of the hopper to ensure the material collection effect.

[0042] In some embodiments, the connecting plate 2 is made of wear-resistant steel.

[0043] See Figure 4 To achieve a detachable connection between the connecting plate 2 and the corner plate 1, the connection structure also includes bolts 5, nuts 6, corner flanges 3 located on both outer sides of the corner plate 1, and connecting flanges 4 located on both outer sides of the connecting plate 2. Bolts 5 pass through the connecting holes of the corner flanges 3 and the connecting flanges 4 and are threaded onto the nuts 6. When two adjacent corner plates 1 are parallel to and tightly fitted with the connecting plate 2, bolts 5 pass through the connecting flanges 4 and the corner flanges 3 and are threaded onto the nuts 6, thus achieving a detachable connection between the corner plates 1 and the connecting plate 2, facilitating the installation and removal of the hopper.

[0044] In some embodiments, both the corner flange 3 and the connecting flange 4 are made of cold-rolled steel plate.

[0045] In some embodiments, the corner flange 3 and the connecting flange 4 are fixedly installed on the outside of the corner plate 1 and the connecting plate 2 by welding, respectively.

[0046] To improve the sealing performance at the connection between corner plate 1 and connecting plate 2, the connecting sides of two adjacent corner plates 1 overlap the two sides of connecting plate 2, and the connecting flange 4 abuts against the corner flange 3. The overlap of the connecting side of corner plate 1 onto connecting plate 2 ensures that the connecting side of corner plate 1 is parallel to and tightly fitted with connecting plate 2, preventing gaps or protrusions at the connection and guaranteeing a tight seal. The abutment between connecting flange 4 and corner flange 3 enhances the tight connection between them, ensuring connection stability and preventing shaking between corner plate 1 and connecting plate 2.

[0047] To ensure that the adjacent corner flange 3 and connecting flange 4 can fit tightly, the corner flange 3 is set perpendicular to the connecting side of the corner plate 1, and the connecting flange 4 is set perpendicular to the connecting side of the connecting plate 2.

[0048] To ensure a secure connection between adjacent corner flanges 3 and connecting flanges 4, each corner flange 3 has one flange extending along the length of the connecting side of the corner plate 1, and each connecting flange 4 has one flange extending along the length of the connecting side of the connecting plate 2. Both corner flanges 3 and connecting flanges 4 have multiple connecting holes, with each connecting hole in the corner flange 3 corresponding to the connecting holes in the adjacent connecting flange 4. The extension of the corner flanges 3 and connecting flanges 4 along the connecting side and the presence of multiple connecting holes make the connection between adjacent corner plates 1 and connecting plates 2 more secure. The one-to-one correspondence of the connecting holes in adjacent corner flanges 3 and connecting flanges 4 ensures that bolts 5 can pass through the connecting holes to connect the two adjacent corner flanges 3.

[0049] In some embodiments, multiple corner flanges 3 and connecting flanges 4 are provided, each corner flange 3 and each connecting flange 4 is provided with a connecting hole. The multiple corner flanges 3 are distributed at intervals along the length direction of the connecting side of the corner plate 1, and the multiple connecting flanges 4 are distributed at intervals along the length direction of the connecting side of the connecting plate 2. Furthermore, the multiple corner flanges 3 of the corner plate 1 correspond one-to-one with the multiple connecting flanges 4 of the adjacent connecting plate 2. This arrangement makes the connection between adjacent corner plates 1 and connecting plates 2 tighter, ensuring the stability of the corner plate 1 connection.

[0050] See Figure 3 In some embodiments, the hopper includes four corner plates 1 and four connecting plates 2, the connecting plates 2 being used to connect two adjacent corner plates 1.

[0051] See Figures 1 to 5 In some embodiments, the diameter of the hopper gradually decreases.

[0052] Figure 5 This is a structural schematic diagram of the grain dryer disclosed in this utility model.

[0053] See Figure 5 This utility model provides a grain dryer, which includes a drying system 7 and a circulation system 8. The circulation system 8 includes a collection hopper as described above, which is located below the drying system 7 and is used to collect the material dried by the drying system 7. The collection hopper can collect the material dried by the drying system 7, and the collection hopper can ensure airtightness to prevent grain from leaking inside the collection hopper and causing waste.

[0054] In some embodiments, the grain dryer further includes a tempering system 12, a lower conveying system 9, a lifting system 10, and an upper conveying system 11. Material in the hopper of the circulation system 8 can be conveyed to the tempering system 12 via the lower conveying system 9, the lifting system 10, and the upper conveying system 11. The tempering system 12 is connected to the drying system 7. The drying system 7 dries the grain. The dried grain enters the hopper of the circulation system 8 and is transported to the lower conveying system 9. The lifting system 10 can lift the grain in the lower conveying system 9 to the upper conveying system 11. The grain in the upper conveying system 11 is then transported to the drying system 7 via the tempering system 12, thereby achieving cyclic drying of the grain and ensuring the drying effect.

[0055] In some embodiments, the grain dryer is a low-temperature batch circulating dryer.

[0056] To facilitate the transport of material from the drying system 7 to the collection hopper, a surrounding plate is connected to the top of the collection hopper to the circulation system 8, and a feeding wheel is installed on the surrounding plate. The feeding wheel can move the material to transport it from the drying system 7 to the collection hopper.

[0057] To improve material conveying efficiency, multiple feeding wheels are installed.

[0058] In some embodiments, the lower conveying system 9 is an auger or a lower chute.

[0059] In some embodiments, the lifting system 10 is a lifting machine.

[0060] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings; however, the present invention is not limited thereto. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention. This includes combining various specific technical features in any suitable manner.
