Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and more specifically, to a grain storage hopper for a grain dryer. Background Technology

[0002] During the process of grain entering the dryer and circulating drying, the grain needs to be continuously fed in and fall from the center of the grain storage hopper. Since the upper part of the inner cylinder at the bottom of the grain storage hopper is a metal cone, an impact force is generated here, causing the grain to break or peel (dehull).

[0003] Therefore, how to avoid or reduce grain breakage in the two stages of grain feeding and recycling has become a technical problem that urgently needs to be solved in the existing technology. Utility Model Content

[0004] The purpose of this invention is to provide a grain storage hopper for a grain dryer that can effectively reduce the impact force when grain falls and reduce the probability of grain breakage.

[0005] This utility model provides a grain storage cylinder for a grain dryer, including a grain inlet layer, a bottom layer, a grain storage layer, and a buffer layer;

[0006] The grain inlet layer, the grain storage layer, the buffer layer, and the bottom layer are arranged sequentially from top to bottom;

[0007] A conical grain receiving hopper is coaxially arranged inside the grain inlet layer, and a conical buffer funnel is coaxially arranged inside the buffer layer.

[0008] The tip diameter of the buffer funnel is smaller than the tip diameter of the grain receiving hopper.

[0009] In a preferred embodiment, the grain storage layer and the buffer layer constitute a grain storage and buffer unit;

[0010] The number of grain storage buffer units is multiple, and the multiple grain storage buffer units are arranged vertically in sequence.

[0011] In a preferred embodiment, the upper opening diameter of the buffer funnel in the lower buffer layer is larger than the upper opening diameter of the buffer funnel in the upper buffer layer.

[0012] In a preferred embodiment, both ends of the grain storage layer and the buffer layer are provided with connecting flanges.

[0013] In a preferred embodiment, the sidewalls of the buffer layer are provided with reinforcing ribs.

[0014] In a preferred embodiment, the grain receiving hopper is connected to the inner wall of the grain feeding layer via a first rib.

[0015] In a preferred embodiment, the buffer funnel is connected to the inner wall of the buffer layer via a second rib.

[0016] In a preferred embodiment, the grain storage layer comprises multiple arc-shaped outer cylindrical pieces;

[0017] Multiple outer cylinder pieces are spliced ​​together to form a cylindrical shape.

[0018] In a preferred embodiment, an inner cylinder is coaxially arranged within the bottom layer;

[0019] The upper end of the inner cylinder has a tapered tip.

[0020] In a preferred embodiment, the leakage rate of the grain receiving hopper is greater than the leakage rate at the tip of the buffer funnel.

[0021] The beneficial effects of this utility model are:

[0022] The grain is collected from the feed hopper via a buffer funnel. The lower end of the feed hopper has a larger outlet, allowing all the grain to flow out. The buffer funnel has a smaller outlet, allowing only a small portion of the grain to flow out. Most of the grain overflows from the upper end of the buffer funnel after it is full. At this point, the grain falling from above only impacts the grain inside the buffer funnel, rather than directly impacting the inner wall of the buffer funnel or the grain storage hopper of the grain dryer. This reduces the impact force and the chance of grain breakage. At the same time, the grain inside the buffer funnel remains in a flowing state during the emptying process of the grain storage hopper, avoiding the risk of grain stagnation.

[0038] The following is combined with Figures 1-7 The following describes some embodiments of the present invention in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0039] This utility model provides a grain storage hopper for a grain dryer, such as... Figure 1 and Figure 2 As shown, it includes a grain inlet layer 1, a bottom layer 6, a grain storage layer 3, and a buffer layer 4; the grain inlet layer 1, the grain storage layer 3, the buffer layer 4, and the bottom layer 6 are arranged sequentially from top to bottom; a conical grain receiving hopper 2 is coaxially arranged in the grain inlet layer 1, and a conical buffer funnel 5 is coaxially arranged in the buffer layer 4; the tip diameter of the buffer funnel 5 is smaller than the tip diameter of the grain receiving hopper 2.

[0040] In this embodiment, the grain storage cylinder of the grain dryer is located at the top of the dryer and is a cylindrical hollow metal thin-walled outer cylinder.

[0041] In this embodiment, the grain storage hopper of the grain dryer is arranged in layers. The grain inlet layer 1 is located at the top of the grain storage hopper of the grain dryer. The grain is fed into the conical grain receiving hopper 2 in the middle of the grain inlet layer 1 from the top. The bottom of the conical grain receiving hopper 2 has a large discharge hole. The function of the grain receiving hopper 2 is to concentrate the grain and let it flow out from the middle.

[0042] Below the grain inlet layer 1 is a single-layer grain storage layer 3, and below the grain storage layer 3 is a buffer layer 4. The buffer layer 4 has a conical buffer funnel 5, which is a conical structure with a small grain outlet at the bottom.

[0043] In this embodiment, the grain receiving hopper 2 and the buffer funnel 5 are similar in shape but different in size. The lower outlet of the grain receiving hopper 2 is larger, allowing all the grain to flow out. The outlet of the buffer funnel 5 is smaller, allowing only a small portion of the grain to flow out. Most of the grain overflows from the upper opening of the buffer funnel 5 after it is filled. Furthermore, during the emptying process of the grain storage hopper, the grain inside the buffer funnel 5 remains in a flowing state, avoiding the risk of grain stagnation. The buffer funnels 5 in the multi-layer buffer layer 4 are also slightly larger at the bottom than at the top, ensuring that the lower buffer funnel 5 can catch the grain overflowing from the upper buffer funnel 5, forming a hierarchical relationship where the lower layer catches the upper layer's grain.

[0044] In a preferred embodiment, the grain storage layer 3 and the buffer layer 4 constitute a grain storage buffer unit; there are multiple grain storage buffer units, which are arranged vertically in sequence.

[0045] In this embodiment, the grain storage hopper is composed of a grain inlet layer 1 → grain storage buffer unit (grain storage layer 3 → buffer layer 4) → grain storage buffer unit (grain storage layer 3 → buffer layer 4) → ... → buffer layer 4 → bottom layer 6, forming a multi-layered composite structure.

[0046] Specifically, in this embodiment, the number of layers in the grain storage hopper can be increased or decreased arbitrarily according to actual needs, and the number of layers in the buffer layer 4 can also be increased or decreased according to the height of the grain storage hopper to ensure the buffering effect.

[0047] Through the process of falling and buffering, the grain eventually falls into and fills the bottom layer 6, and gradually fills the entire grain storage hopper, effectively avoiding the problem of grain breakage caused by impact during the grain feeding and circulation process.

[0048] In a preferred embodiment, the upper opening diameter of the buffer funnel 5 in the lower buffer layer 4 is larger than the upper opening diameter of the buffer funnel in the upper buffer layer 4.

[0049] In this embodiment, in adjacent buffer layers 4, the upper opening of the lower buffer funnel 5 is larger than the upper opening of the upper buffer funnel 5, ensuring that the grain overflowing from the upper buffer funnel 5 or the receiving layer can fall into the lower buffer funnel 5.

[0050] When the upper buffer funnel 5 begins to overflow from the top, it can be caught by the lower buffer funnel 5 and enter the lower buffer funnel 5. When the lower buffer funnel 5 is also full, the lower buffer funnel 5 overflows from the top edge and falls into the lower buffer funnel 5 or the bottom layer 6.

[0051] This design ensures that the lower buffer funnel 5 can fully receive the grain overflowing from the upper buffer funnel 5, forming a progressively layered buffer structure, thus preventing the grain from breaking during its descent due to the inability to be effectively caught.

[0052] In a preferred embodiment, both ends of the grain storage layer 3 and the buffer layer 4 are provided with connecting flanges 10.

[0053] In this embodiment, the grain storage layer 3 and the buffer layer 4 are formed into a module by the connection flange 10, allowing for convenient modular assembly of each layer of the grain storage hopper. Through the connection flange 10, the number of grain storage layer 3 and buffer layer 4 can be quickly increased or decreased according to actual needs, flexibly adjusting the capacity and buffering effect of the grain storage hopper.

[0054] Meanwhile, the design of the connecting flange 10 also enhances the overall structural stability of the grain storage silo. During assembly, the connecting flange 10 ensures a tight connection between each layer, preventing structural loosening due to impact or vibration of the grain.

[0055] Furthermore, the modular design makes the maintenance and replacement of grain storage silos more convenient. If a layer is damaged or needs upgrading, that layer can be replaced individually without disassembling and reassembling the entire grain storage silo.

[0056] It is understood that in this embodiment, the connection method at both ends of the grain storage layer 3 and the buffer layer 4 is the connection flange 10. However, it is not limited to the connection flange 10. It can also be other detachable connection methods, such as snap-fit ​​or pin connection, as long as the installation stability of the grain storage layer 3 and the buffer layer 4 can be guaranteed.

[0057] In a preferred embodiment, the sidewall of the buffer layer 4 is provided with reinforcing ribs 9.

[0058] In this embodiment, the height of the buffer layer 4 is lower than that of the grain storage layer 3. After setting the reinforcing ribs 9 on the side wall of the buffer layer 4, the structural strength and stability of the buffer layer 4 can be significantly enhanced.

[0059] During the fall of the grain, the buffer layer 4 needs to withstand a large impact force. The reinforcing ribs 9 can effectively disperse these impact forces and prevent the buffer layer 4 from deforming or being damaged due to excessive local stress.

[0060] By enhancing the structural strength of the buffer layer 4, the reinforcing rib 9 can effectively extend the service life of the buffer layer 4, reduce the frequency of repair and replacement due to structural damage, and lower the maintenance cost of the equipment.

[0061] The design of the reinforcing rib 9 can further optimize the buffering effect of the buffer layer 4. By rationally distributing the position and number of the reinforcing ribs 9, it can be ensured that the buffer layer 4 maintains good buffering performance when subjected to impact force, further reducing the breakage rate of grain.

[0062] Specifically, in this embodiment, the reinforcing rib 9 is vertically arranged on the outer wall of the buffer layer 4, and the connecting flange 10 connects the two ends of the buffer layer 4.

[0063] In a preferred embodiment, the grain receiving hopper is connected to the inner wall of the grain feeding layer 1 via the first rib plate 8.

[0064] In this embodiment, the grain receiving hopper 2 is fixedly connected to the inner wall of the grain feeding layer 1 in a uniform radial pattern by multiple first ribs 8 around it. The connection method can be bolted, welded, or riveted, as long as the first ribs 8 can be fixedly connected to the grain receiving hopper 2 and the inside of the grain feeding layer 1.

[0065] More specifically, in this embodiment, the first rib plate 8 is radially distributed, which can evenly disperse the impact force of the grain on the grain receiving hopper 2 and prevent the grain receiving hopper 2 from deforming or being damaged due to excessive local stress.

[0066] In a preferred embodiment, the buffer funnel 5 is connected to the inner wall of the buffer layer 4 via the second rib 13.

[0067] In this embodiment, the buffer funnel 5 is set in the same way as the grain receiving hopper 2. Since the size of the buffer funnel 5 is different from that of the grain receiving hopper 2, the parameters of the second rib 13 and the first rib 8 are different.

[0068] Meanwhile, the diameter parameters of the buffer funnels 5 in each buffer layer 4 are different, and the corresponding parameters such as the length of the second rib 13 will also change accordingly.

[0069] In a preferred embodiment, the grain storage layer 3 includes multiple arc-shaped outer cylindrical pieces 12; the multiple outer cylindrical pieces 12 are spliced ​​together to form a cylindrical shape.

[0070] In this embodiment, the grain storage layer 3 is composed of four or two outer cylinder pieces 12, which can be connected and combined to form a single-layer cylindrical grain storage layer 3 through vertical flanges.

[0071] At this time, the vertical flange 11 can act as a reinforcing rib 9, thereby increasing the load-bearing capacity of the grain storage layer 3, ensuring the safety of the grain storage layer 3 during grain storage, and improving the service life of the grain storage layer 3.

[0072] Meanwhile, in this embodiment, the grain storage layer 3 is set up by splicing multiple arc-shaped outer cylinder single pieces 12, which makes the grain storage layer 3 easy to transport and allows only the damaged part to be replaced when it is damaged, thus reducing maintenance costs.

[0073] In a preferred embodiment, an inner cylinder 7 is coaxially arranged inside the bottom layer 6; the upper end of the inner cylinder 7 is a conical tip.

[0074] In this embodiment, the conical tip at the upper end of the inner cylinder 7 can effectively guide the grain smoothly into the bottom layer 6, preventing the grain from accumulating or clogging at the entrance of the bottom layer 6. The conical tip can disperse the falling direction of the grain, making the grain evenly distributed in the bottom layer 6, which helps to improve the operating efficiency of the grain storage silo and avoid equipment failure caused by grain accumulation.

[0075] Meanwhile, the conical structure can better withstand the impact of grain, reducing wear and damage to the bottom layer 6; the grain in the bottom layer 6 is easier to clean and discharge, facilitating the maintenance and cleaning of the grain storage silo.

[0076] In a preferred embodiment, the leakage rate of the grain receiving hopper 2 is greater than the leakage rate of the tip of the buffer funnel 5.

[0077] In this embodiment, the diameter of the grain outlet at the bottom of the receiving hopper is relatively large, which ensures that the grain has a high flow rate when entering the grain storage layer 3, so that the grain can quickly flow out of the receiving hopper and enter the next grain storage layer 3.

[0078] The small outlet at the tip of the buffer funnel 5 results in a relatively slow grain outflow rate, ensuring sufficient residence time for the grain within the buffer funnel 5. This creates a buffer pad effect within the buffer funnel 5, allowing the grain falling from the upper layer to accumulate on top of the grain in the buffer funnel 5, thus reducing the impact on the grain.

[0079] As can be seen from the above, the grain storage hopper of the grain dryer provided by this utility model, based on the overall structure of the storage hopper, allows the grain to be collected in the receiving hopper 2 of the grain inlet layer 1 after being delivered by external equipment. The grain then flows down from the outlet of the receiving hopper 2 and enters the first grain storage layer 3. Since the grain has a certain falling speed and kinetic energy after falling a certain height, a buffer layer 4 is set in the layer below the first grain storage layer 3 to reduce its falling speed and kinetic energy. The receiving hopper 2 of the buffer layer 4 reduces its falling speed, thereby reducing the impact force. As the grain flows, the grain in the buffer funnel 5 will... The grain flows out from the bottom round hole of the buffer funnel 5. Since the lower end of the buffer funnel 5 has a small diameter, most of the grain overflows through the upper edge of the buffer funnel 5 and flows into the second grain storage layer 3. Then, it falls into the next buffer layer 4 after passing through the second grain storage layer 3. At this time, the grain falling from the feed hopper will fall on the grain in the buffer funnel 5, thereby reducing the impact force of the grain. As the grain is loaded, the surface of the grain gradually rises. During the rising process, each layer of buffer funnel 5 is gradually buried in the grain pile. The grain receiving hopper 2 that has been buried no longer receives grain. At this time, the grain falling from above falls directly onto the grain surface of the lower layer, thereby reducing the impact force of the grain.

[0080] Through falling and buffering, and after one or more buffering processes, the grain falls into and fills the bottom layer 6, and gradually fills the entire grain storage silo.

[0081] As can be seen from the above, this utility model breaks through the conventional grain dryer's breakage process by identifying another key link in grain breakage caused by impact during the grain feeding and circulation process, namely the grain storage hopper of the dryer. The structure of the grain storage hopper is layered, and each layer is improved to reduce or avoid breakage problems during the grain feeding and drying circulation process.

[0082] The beneficial effects of this utility model are:

[0083] The grain falling from the feed hopper is collected by the buffer funnel 5. The lower end of the feed hopper 2 has a larger outlet, allowing all the grain to flow out. The outlet of the buffer funnel 5 is smaller, allowing only a small portion of the grain to flow out. Most of the grain overflows from the upper end of the buffer funnel 5 after it is full. At this time, the grain falling from above will only impact the grain inside the buffer funnel 5, and will not directly impact the inner wall of the buffer funnel 5 or the grain storage cylinder of the grain dryer, thus reducing the impact force and the chance of grain breakage. At the same time, during the process of emptying the grain storage cylinder, the grain inside the buffer funnel 5 is always in a flowing state, avoiding the risk of grain stagnation.

[0084] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
