Description

Technical Field

[0001] This utility model relates to the field of grain storage bin technology, specifically a sealed grain storage bin with a separate grain compartment. Background Technology

[0002] A grain storage bin is a special container used to store grains (such as cereals, beans, feed, etc.). It is usually designed with a sealed or semi-sealed structure to ensure that the grains are protected from external factors such as moisture, insects, mold, and rodents during storage, while maintaining the freshness and quality of the grains.

[0003] However, existing vacuum grain storage containers are basically single-barrel structures, meaning different types of grain can only be stored in the same area. Some grain storage containers are equipped with a plastic compartment to solve the above problem, but even with the addition of the plastic compartment, because air circulates between the plastic compartment and the bottom of the grain storage container, opening the lid every day will still cause the grain in both the upper and lower areas to become damp, resulting in damp grain that is prone to mold and leads to grain waste. Utility Model Content

[0004] The purpose of this invention is to propose a sealed grain storage bin with a separate grain compartment, which aims to solve the technical problem that in the existing grain storage bin structure, the air in the plastic compartment used for separation and the upper and lower areas of the bottom of the grain storage bin can circulate with each other, which can easily cause the grain in the upper and lower areas to become damp together.

[0005] To achieve the above objectives, this utility model proposes a sealed grain storage bin with a separate grain compartment, comprising a bin body;

[0006] The top cover is movably mounted on the barrel to seal the barrel. The top cover is provided with a vacuum module for evacuating the barrel and a vent hole for venting the gas inside the barrel to the outside.

[0007] The grain distribution bin is located inside the barrel to divide the barrel into a first area and a second area, and the grain distribution bin is equipped with a ventilation component, which has a vent hole and an exhaust hole.

[0008] The handle is rotatably disposed within the grain distribution bin, such that: when the handle is rotated to the first position, it blocks the vent hole of the ventilation component, allowing gas in the second area to flow unidirectionally to the first area only through the vent hole; when the handle is rotated to a position other than the first position, it no longer blocks the vent hole of the ventilation component, allowing gas in the first area and the second area to circulate between each other.

[0009] Preferably, the upper cover is provided with a vacuum module, which is used to vacuum the barrel body;

[0010] The top cover is also equipped with a pressure relief valve for relieving pressure and a vent hole for venting the gas inside the barrel to the outside.

[0011] Preferably, the ventilation component is disposed at one end of the inner wall of the grain distribution bin, and the ventilation component is provided with a vent hole;

[0012] When the handle is rotated to the first position, its lower end face abuts against the ventilation component to block the vent hole; when the handle is rotated to a position other than the first position, its lower end face no longer abuts against the ventilation component and no longer blocks the vent hole.

[0013] Preferably, the venting assembly includes a first boss and a first one-way valve plug. The first boss has at least one vent hole and a mounting hole. The first one-way valve plug is detachably installed in the mounting hole. The first one-way valve plug has a through vent hole. The top of the first one-way valve plug extends to both sides to form a sealing portion. The sealing portion overlaps the first boss and is located above the vent hole. The lower end of the handle has a pressure ring, such that:

[0014] When the handle is rotated to the first position, the lower end face of the pressure ring abuts against the first one-way valve sealing member to block the periphery of the vent hole. The vacuum module evacuates the barrel, and the gas in the second region flows to the first region through the vent hole, thereby gradually reducing the gap between the sealing part and the vent hole until the vent hole is blocked. When the handle is rotated to a position other than the first position, the pressure ring no longer blocks the vent hole, and the gas in the first region flows to the second region through the vent hole.

[0015] Preferably, the first one-way valve sealing member is disposed in the middle of the first boss, and two exhaust holes are respectively provided on both sides of the first boss.

[0016] Preferably, the venting assembly includes a second protrusion, on which are spaced-apart sealing elements and vent holes. The sealing elements contain the through-hole vent, and the vent holes contain a second one-way valve sealing element. The lower end of the handle is provided with a pressure column, such that:

[0017] When the handle is rotated to the first position, the pressure column is inserted into the vent hole to block it, and the vacuum module evacuates the barrel. The gas in the second area flows to the first area through the second one-way valve sealing element. When the handle is rotated to a position other than the first position, the pressure column is pulled out of the vent hole and no longer blocks the vent hole. The gas in the first area flows to the second area through the vent hole.

[0018] Preferably, both sides of the inner wall of the grain storage bin are provided with locking components, and the two sides of the locking components protrude outward to form a first locking part and a second locking part; both sides of the handle are provided with slots, and the locking components are respectively inserted into the corresponding slots;

[0019] The slot is provided with a slotting groove for the first engaging part and the second engaging part to rotate. The slotting groove is provided with a limiting protrusion. The limiting protrusion is used to abut against the first engaging part when the handle is rotated to the first position, and the handle is in a retracted state. When the handle is rotated to the second position, the handle abuts against the second engaging part, and the handle is in a lifted state.

[0020] Preferably, the handle is further provided with a cover, which covers the outside of the slot.

[0021] Preferably, the edge of the grain distribution bin overlaps the barrel body, and the bottom end of the grain distribution bin is provided with a first sealing ring that abuts against the outer edge of the barrel body.

[0022] Preferably, the top of the barrel extends outward to form a platform surface, and the bottom of the top cover is also provided with a second sealing ring, which is used to abut against the upper end of the platform surface when the top cover is closed.

[0023] The sealed grain storage tank with separate grain compartments disclosed in this utility model has the following beneficial effects:

[0024] By adding a rotatable handle inside the grain compartment, when the handle is rotated to the first position, the flat handle can block the vent hole of the ventilation component, allowing air from the second zone to flow unidirectionally to the first zone only through the exhaust hole, thus achieving a vacuum in the second zone. After vacuuming, the second zone remains sealed as long as the handle is not lifted, and the first zone inside the container also remains sealed as long as the top cover is not opened. This structure allows for the separate sealing of each section inside the container, and the second zone can be opened or closed after vacuuming. Sealing and depressurization are relatively simple; just swing the handle up and down, without needing positioning or any tools, making it very flexible to use. Attached Figure Description

[0044] like Figures 1 to 13 As shown, a sealed grain storage bin with a separate grain compartment includes a bin body 1;

[0045] The upper cover 2 is movably mounted on the barrel 1 to seal the barrel 1. The upper cover 2 is provided with a vacuum module 21 for evacuating the barrel 1 and an upper cover vent 22 for venting the gas inside the barrel 1 to the outside.

[0046] The grain distribution bin 3 is located inside the barrel 1 to divide the barrel 1 into a first area 11 and a second area 12. The grain distribution bin 3 is provided with a ventilation component 4, which is provided with a vent hole 41 and an exhaust hole 42.

[0047] The handle 5 is rotatably disposed within the grain distribution bin 3, such that: when the handle 5 is rotated to the first position, it blocks the vent hole 41 of the ventilation component 4, so that the gas in the second region 12 can only flow unidirectionally to the first region 11 through the exhaust hole 42; when the handle 5 is rotated to a position other than the first position, it no longer blocks the vent hole 41 of the ventilation component 4, and the gas in the first region 11 and the second region 12 can circulate between each other.

[0048] In this design, the barrel body 1 and the top cover 2 form an independent grain storage space. Various types of grains can be stored inside the barrel body 1, and the top cover 2 can be hinged or otherwise fixed to the barrel body 1. To increase the partitioning within the barrel body 1, this design adds a grain divider 3. The grain divider 3 is located inside the barrel body 1 and is typically fixed to the upper half of the barrel body 1 to divide the space inside the barrel body 1 into a first area 11 (the area where the grain divider 3 is located) and a second area 12 (the lower part of the barrel body 1). Furthermore, the grain divider 3 can be equipped with left and right partitions according to actual needs to meet the requirements of compartmentalized storage, providing flexibility in use. To improve the sealing effect of each area inside the barrel 1, this design adds a rotatable handle 5 inside the grain distribution bin 3. The two sides of the handle 5 are movably connected to the two sides of the inner wall of the grain distribution bin 3. The handle 5 has three states when rotated: raised (handle 5 is in a vertical position), intermediate position, and retracted (handle 5 is in a horizontal position). The retracted position is the state when the handle 5 is rotated to the first position. In this position, the horizontally placed handle 5 can block the vent hole 41 of the ventilation component 4, allowing air in the second area 12 to flow unidirectionally to the first area 11 only through the exhaust hole 42, thus achieving a vacuum in the second area 12. After vacuuming, the second area 12 will remain sealed as long as the handle 5 is not raised. Similarly, the first area 11 inside the barrel 1 will also remain sealed as long as the top cover 2 is not opened. After opening the top cover 2, air can flow into the first area 11 from the outside. After raising the handle 5, air can flow from the first area 11 into the second area 12.

[0049] The simple installation, fixing, and venting / pressure relief structure of the grain storage bin allows for separate sealing of each section within the bin 1, resulting in good sealing performance. It also eliminates the need for numerous spare parts, eliminating concerns about parts falling out during use. It is convenient and cost-effective. Both the first zone 11 and the second zone 12 in this design can be vacuum-sealed. The second zone 12 can be left open after vacuuming to reduce air ingress, making it suitable for both short and long feeding cycles. For short-term feeding, grain can be placed in the upper first zone 11, while the second zone 12 can be used for long-term storage. It can also serve as a transfer compartment, allowing grain to be scooped into the distribution bin 3 in the first zone 11 and then carried elsewhere for distribution. The distribution bin 3 can be placed in any direction within the bin 1 without requiring precise alignment; users can place it without conscious effort. Sealing and pressure relief are simple, requiring only the up-and-down movement of the handle 5, without the need for positioning or any tools, making it highly flexible.

[0050] Furthermore, the ventilation component 4 is disposed at one end of the inner wall of the grain distribution bin 3, and the ventilation component 4 is provided with a vent hole 41;

[0051] When the handle 5 is rotated to the first position, its lower end face abuts against the ventilation component 4 to block the vent hole 41; when the handle 5 is rotated to a position other than the first position, its lower end face no longer abuts against the ventilation component 4 and no longer blocks the vent hole 41.

[0052] like Figures 1 to 13 As shown, the handle 5 typically has two states: retracted and raised. When raised, the handle 5 can be rotated approximately 90 degrees to the left or right to retract. When the handle 5 is retracted, it is essentially flat, which is the first position. The flat handle 5 can rest against the top of the ventilation component 4 and block the vent hole 41, preventing air from flowing from the second region 12 to the first region 11. When the vacuum module 21 is activated to completely remove the air from the second region 12, a vacuum state in the second region 12 can be guaranteed. If air needs to enter the second region 12, simply rotate the handle 5 so that it no longer presses against the ventilation component 4, allowing air from the first region 11 to flow into the second region 12 through the vent hole 41.

[0053] Furthermore, the venting assembly 4 includes a first boss 43 and a first one-way valve plug 44. The first boss 43 has at least one vent hole 42 and a mounting hole 431. The first one-way valve plug 44 is detachably installed in the mounting hole 431. The first one-way valve plug 44 has a through vent hole 41. The top of the first one-way valve plug 44 extends to both sides to form a sealing part. The sealing part overlaps the first boss 43 and is located above the vent hole 42. The lower end of the handle 5 is provided with a pressure ring 51, such that:

[0054] When the handle 5 is rotated to the first position, the lower end face of the pressure ring 51 abuts against the first one-way valve sealing member 44 to block the periphery of the vent hole 41. The vacuum module 21 evacuates the barrel 1, and the gas in the second region 12 flows to the first region 11 through the exhaust hole 42, thereby gradually reducing the gap between the sealing part and the exhaust hole 42 until the exhaust hole 42 is blocked. When the handle 5 is rotated to a position other than the first position, the pressure ring 51 no longer blocks the vent hole 41, and the gas in the first region 11 flows to the second region 12 through the vent hole 41.

[0055] In this embodiment, as Figures 2 to 8 As shown, after loading the grain, press down on the handle 5 to rotate it to the first position. At this time, the pressure ring 51 at the lower end of the handle 5 presses against the first one-way valve sealing member 44 on the first boss 43 and blocks the vent hole 41. Close the upper cover 2, and the vacuum module 21 of the upper cover 2 will start automatically. At this time, the air in the second area 12 will be discharged from the vent hole 42 of the first boss 43 to the first area 11 (i.e., the grain bin 3 area). The first one-way valve sealing member 44 can be a rubber plug. Due to the negative pressure, the first one-way valve sealing member 44 (rubber plug) will be blocked. The sealing part of the plug will get tighter and tighter against the top of the vent 41, gradually reducing the gap between the sealing part and the vent 42 until the vent 42 is blocked. At the same time, the first sealing ring 32 of the grain bin 3 will also press tighter and tighter against the barrel 1. As the air is discharged, the second area 12 gradually reaches a negative pressure sealing state. The air in the first area 11 is also discharged from the top cover 2 to the outside of the barrel 1. Under negative pressure, the second sealing ring 24 of the top cover 2 presses tighter and tighter against the platform surface 13 of the barrel 1, so that the entire grain storage barrel is in a sealed state.

[0056] When it is necessary to open, press the pressure relief valve 23 of the top cover 2 to release the air. The air in the first area 11 is discharged from the vent hole 22 of the top cover. When taking out the grain, as long as the handle 5 is not lifted and is kept in the first position, the second area 12 can be kept in a vacuum state. If the second area 12 needs to be depressurized, simply lift the handle 5 upwards until it is not in the first position. The pressure ring 51 on the handle 5 will leave the first one-way valve sealing part 44, and the air will enter the second area 12 from the vent hole 41, and the second area 12 can be depressurized.

[0057] Furthermore, the first one-way valve sealing member 44 is disposed in the middle of the first boss 43, and two exhaust holes 42 are respectively provided on both sides of the first boss 43. The first one-way valve sealing member 44 is disposed in the middle of the first boss 43, and exhaust holes 42 are respectively provided on both sides of the first sealing member 46. The top of the first sealing member 46 located in the middle extends to both sides, so that the two sides of the first sealing member 46 overlap the two exhaust holes 42 respectively. When two exhaust holes 42 are provided, the exhaust speed is faster and the working efficiency is higher.

[0058] Furthermore, the venting assembly 4 includes a second protrusion 45, on which are spaced-apart sealing members 46 and vent holes 42. The sealing member 46 contains a through-hole vent hole 41, and the vent hole 42 contains a second one-way valve sealing member 451. The lower end of the handle 5 is provided with a pressure column 52, such that:

[0059] When the handle 5 is rotated to the first position, the pressure column 52 is inserted into the vent hole 41 to block it, and the vacuum module 21 evacuates the barrel 1. The gas in the second region 12 flows to the first region 11 through the second one-way valve sealing member 451. When the handle 5 is rotated to a position other than the first position, the pressure column 52 is pulled out from the vent hole 41 and no longer blocks the vent hole 41. The gas in the first region 11 flows to the second region 12 through the vent hole 41.

[0060] In addition to the above embodiments, this solution also provides another embodiment of the ventilation component 4. In this embodiment, as... Figures 9 to 10 As shown, the second protrusion 45 is provided with a vent hole 41 and an exhaust hole 42. When the handle 5 is pressed down to the first position (i.e., the retracted state), the pressure column 52 at the lower end of the handle 5 is pressed into the vent hole 41 of the sealing member 46, sealing the vent hole 41. When the vacuum module 21 starts to vacuum, the gas is drawn from the barrel 1 to the outside, and the air in the second region 12 also flows from the second one-way valve sealing member 451 to the second region 12 (i.e., the region where the grain bin 3 is located). When depressurizing, simply lift the handle 5 upwards so that the pressure column 52 at the lower end of the handle 5 leaves the vent hole 41 of the sealing member 46. At this time, the air in the first region 11 enters the second region 12 from the vent hole 41, and the second region 12 is depressurized.

[0061] In actual production, the sealing element 46 can be a rubber plug with a through hole or a one-way valve with a through hole, where the through hole is the vent hole 41. The sealing elements 41 and 46 can also be solid rubber plugs without holes. When depressurizing the second region 12, the sealing element 41 or 46 can be manually pried open to expose the vent hole 42 for venting. The main function of the second one-way valve sealing element 451 is to ensure that air in the second region 12 flows unidirectionally to the first region 11, and that air in the first region 11 cannot flow from the second one-way valve sealing element 451 to the second region 12.

[0062] Furthermore, both sides of the inner wall of the grain storage 3 are provided with locking parts 31, and the two sides of the locking parts 31 protrude outward to form a first locking part 311 and a second locking part 312; both sides of the handle 5 are provided with slots 53, and the locking parts 31 are respectively inserted into the corresponding slots 53.

[0063] The slot 53 is provided with a positioning slide groove 531 for the first engaging part 311 and the second engaging part 312 to rotate. The positioning slide groove 531 is provided with a limiting protrusion 532. The limiting protrusion 532 is used to abut against the first engaging part 311 when the handle 5 is rotated to the first position, and the handle 5 is in a retracted state. When the handle 5 is rotated to the second position, it abuts against the second engaging part 312, and the handle 5 is in a lifted state.

[0064] When installing the handle 5 onto the grain distribution bin 3, align the first locking position 533 in the slot 53 of the handle 5 with the first locking part 311 of the locking member 31, and align the second locking position 534 with the second locking part 312 of the locking member 31. Then the handle 5 can be installed onto the grain distribution bin 3. After installation, see... Figures 11 to 13 As shown, the first engaging part 311 abuts against the limiting protrusion 532 to prevent the handle 5 from pressing down further. At this time, there is a step difference between the limiting protrusion 532 and the locking groove 531, so that the handle 5 can rotate freely through the locking groove 531. The grain bin 3 and the handle 5 are then installed.

[0065] In actual use, for example, after loading grain, the handle 5 needs to be pressed down to change from the lifted state to the retracted state. The limiting protrusion 532 changes from the second position to the first position, that is, from pressing against the second engaging part 312 to the first engaging part 311. This locking position informs the user that the handle 5 has been pressed all the way down. At the same time, the aforementioned protrusion can also play a limiting role. If pressure needs to be released, simply lift / raise the handle 5, which is in the retracted state, so that the handle 5 no longer presses against the venting component 4. Air enters the second area 12 through the vent hole 41, and the second area 12 can be depressurized. At this time, the handle 5 can be fully lifted. The limiting protrusion 532 changes from pressing against the first engaging part 311 to pressing against the second engaging part 312. This locking position informs the user that the handle 5 has been opened to the maximum angle, and the entire grain bin 3 can be lifted directly. At the same time, it also plays a limiting role for the handle 5, so that the handle 5 will not turn around when lifting and using it.

[0066] Furthermore, the handle 5 is also provided with a cover 54, which covers the outside of the slot 53. The cover 54 covers the slot 53 on the handle 5, which on the one hand makes the design of the handle 5 more aesthetically pleasing; on the other hand, it can also prevent the grain in the grain bin 3 from falling into the slot 53 and affecting the normal rotation of the handle 5.

[0067] Furthermore, the edge of the grain distribution bin 3 overlaps with the barrel body 1, and the bottom end of the grain distribution bin 3 is provided with a first sealing ring 32 that abuts against the outer edge of the barrel body 1. When the grain distribution bin 3 is placed on the barrel body 1, the first sealing ring 32 at the lower end of the grain distribution bin 3 contacts the outer edge of the barrel body 1 to achieve a better sealing effect. When the vacuum module 21 vacuums, the first sealing ring 32 tightly sucks the grain distribution bin 3 and the barrel body 1, preventing air from the upper part of the grain distribution bin 3 (i.e., the first region 11) from entering the lower part of the grain distribution bin 3 (i.e., the second region 12).

[0068] The entire grain distribution bin 3 in this solution can be cleaned. The first sealing ring 32 and the aforementioned one-way valve sealing parts 46 can be removed for cleaning, leaving no dead corners for slag accumulation.

[0069] Furthermore, the top of the barrel 1 extends outward to form a platform surface 13, and the bottom of the upper cover 2 is also provided with a second sealing ring 24. The second sealing ring 24 is used to abut against the upper end of the platform surface 13 when the upper cover 2 is closed. Since the top of the barrel 1 has an outwardly extending platform surface 13, the second sealing ring 24 can improve the sealing between the upper cover 2 and the barrel 1. When the vacuum module 21 vacuums, the second sealing ring 24 tightly sucks the barrel 1 and the upper cover 2 to prevent air from entering.

[0070] Furthermore, the upper cover 2 is also equipped with a pressure relief valve 23 for depressurization. When the vacuum module 21 on the upper cover 2 is activated, the air inside the barrel 1 can be removed, maintaining a vacuum state inside the barrel 1 and extending the storage time of the grain. When it is necessary to open the barrel 1, the pressure relief valve 23 on the upper cover 2 can be opened.

[0071] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
