Description

Technical Field

[0001] The present invention relates to the technical field of grain storage bins, and more specifically, it relates to a grain storage bin with intelligent temperature and humidity monitoring. Background Art

[0002] Currently, when traditional granaries are dealing with the problem of grain rot, although they have a certain detection ability, the treatment solutions have obvious deficiencies; traditional granaries generally use devices such as temperature sensors and humidity sensors to monitor the internal environment of the granary. By means of abnormal changes in the temperature and humidity of the grain pile, it is possible to detect to a certain extent whether the grain has rotted; for example, when local rot occurs in the grain pile, the activities of microorganisms will cause the temperature in this area to rise and the humidity to increase. After the sensors detect these changes, the staff can judge that the grain may be rotten; and then corresponding treatment is carried out according to the situation.

[0003] Traditional granaries usually adopt two methods for treatment: ventilation and manual sunning. Ventilation is to use ventilation equipment to make the air inside and outside the granary circulate, reduce the humidity inside the granary and take away heat. This method is only applicable to ventilated granaries and is very unfriendly to sealed granaries. To a certain extent, it can relieve the hot and humid environment of the grain pile and inhibit the further growth of microorganisms, but it has almost no substantial repair effect on the rotten part of the grain.

[0004] Manual sunning is to transport the grain in the granary to an open outdoor area, and through sunlight irradiation and manual turning, accelerate the evaporation of water in the grain and improve the storage conditions of the grain; however, this process requires a large amount of manpower and is very time-consuming; moreover, during the sunning process, the grain is easily secondarily polluted by the external environment, such as dust and impurities mixing in, and frequent turning may also cause damage to the grain particles, affecting the quality of the grain; more importantly, it is difficult to completely remove the rotten and deteriorated part by manual sunning. Once it rains, manual sunning simply cannot be carried out, and the problem of grain rot will deteriorate during the waiting process, ultimately resulting in a large amount of grain deteriorating due to the inability to be treated in a timely and effective manner, bringing serious economic losses to grain storage enterprises. Therefore, we have designed a grain storage bin with intelligent temperature and humidity monitoring. Summary of the Invention

Detailed implementation manners

[0021] Now, the subject matter described herein will be discussed with reference to exemplary implementation manners. It should be understood that discussing these implementation manners is only to enable those skilled in the art to better understand and thus implement the subject matter described herein. Without departing from the scope of protection of the content of this specification, changes can be made to the functions and arrangements of the elements discussed. Each example can omit, substitute, or add various processes or components as needed. Additionally, the features described in some examples can also be combined in other examples.

[0022] As Figures 1 to 11 shown, an intelligent temperature and humidity monitoring grain storage bin according to an embodiment of the present invention includes a storage bin 1 with a driving mechanism built therein; a pressing plate 2 is rotatably installed in the storage bin 1 and is connected to the driving mechanism; a positioning pipe 501 is fixedly installed on the pressing plate 2, and a downward probing mechanism is arranged inside it; a wrapping mechanism is slidably installed inside the downward probing mechanism, which includes an arc-shaped cover 512 installed with a heat insulation soft layer 511, and the arc-shaped cover 512 is driven by an unfolding assembly; when an abnormality occurs in the grain in the storage bin 1, the driving mechanism, based on the temperature change, drives the downward probing mechanism on the pressing plate 2 to probe the rotting area, and cooperates with the wrapping mechanism to isolate the abnormal part of the grain, and the wrapping range of the wrapping mechanism for the grain can be adaptively adjusted according to the scale of the rotting area.

[0023] Specifically, when the storage bin 1 needs to be filled with grain, the grain is conveyed from the top of the granary through traditional conveying facilities. Since there are through holes provided on the pressing plate 2, the grain passes through the pressing plate 2 and enters the bottom of the granary, thus forming a grain pile inside the granary. The density inside the grain pile is uneven. Affected by factors such as gravity and particle accumulation state in different parts, the air circulation in the high-density area is severely blocked, and a large amount of heat and water vapor accumulate, forming a high-temperature and high-humidity environment; while in the low-density area, due to excessive air circulation, the moisture of the grain is lost too quickly, affecting the quality. In this way, when the grain pile accumulates to a certain height, the grain pile will squeeze the pressing plate 2. Due to the density of the grain, the pressing plate 2 cannot be completely pressed into the grain interior. After only partially pressing in, it can only stop moving, and because of the pressing mechanism, it acts on the grain pile in the reverse direction, so that the grain pile is stacked stably, ensuring that the gaps between the grains are uniform. There is a temperature sensor installed in the granary, and the temperature sensor will detect the temperature inside the granary. When the temperature continues to rise, the pressing plate 2 will first move upward. Subsequently, the driving mechanism controls the pressing plate 2 to rotate, and the pressing plate 2 controls the downward probing mechanism to rotate. Since the increase in temperature is mostly due to the decay of the grain inside the grain pile, the density of the decayed area will decrease. And the downward probing mechanism is used to apply a downward force. When it encounters a low-density drive, it will move downward, so that the driving mechanism drives the bellows 510 to control the wrapping mechanism to move downward to the decayed area, isolate the grain in the decayed area, reduce the heat dissipation. Finally, after the temperature returns to normal, the wrapping mechanism will lift and separate the isolated grain.

[0024] Please refer to Figure 2 and Figure 3 The driving mechanism includes a storage box 301 fixedly connected to the storage bin 1; a water pump 302 is fixedly installed inside the storage box 301, and a first connecting pipe 303 is connected thereto; one end of the rotating assembly is fixedly connected to the first connecting pipe 303, and the other end is connected to the storage box 301 through a second connecting pipe 305.

[0025] The rotating assembly includes a driving disk 310. Both ends of the driving disk 310 are fixedly connected with fifth connecting pipes 309. The fifth connecting pipe 309 on the right side of the driving disk 310 is connected to the first connecting pipe 303 through a switching valve 312, and the fifth connecting pipe 309 on the left side of the driving disk 310 is connected to the second connecting pipe 305.

[0026] A rotating pipe 313 is rotatably installed on the driving disk 310, and an impeller 306 is fixedly installed thereon. Its bottom end is fixedly connected to the pressing plate 2; the driving mechanism further includes a rotating ring 311 rotatably connected to the rotating pipe 313; an installation box 304 is fixedly installed on the pressing plate 2 and fixedly connected to a positioning pipe 501, and is communicated with the rotating ring 311 through a sixth connecting pipe 314; one end of a fourth connecting pipe 308 is communicated with the switching valve 312, and the other end is communicated with the rotating pipe 313.

[0027] The water pump 302 is controlled by a temperature controller. When the temperature controller detects that the temperature in the granary reaches the preset value, it locally controls the water pump 302 to start. The water pump 302 will pump the water source in the storage box 301 into the first connecting pipe 303, and then transport it back to the storage box 301 through the switching valve 312, the fifth connecting pipe 309, the driving disc 310, and the second connecting pipe 305. In this way, with the flow of water, the impeller 306 can be rotated. The rotation of the impeller 306 will drive the rotating pipe 313 to rotate, and the rotation of the rotating pipe 313 will drive the pressing plate 2 to rotate. In this way, the pressing plate 2 will drive the downward detection mechanism in the installation box 304 to rotate, so as to detect the grain decay point.

[0028] Please refer to Figure 4 , the downward detection mechanism includes a positioning pipe 501 fixedly connected to the pressing plate 2; the telescopic pipe 502 is slidably installed inside the positioning pipe 501 and is connected to the pressing plate 2 through the second spring 503.

[0029] When the grain in the grain pile decays and the pressing plate 2 is driven by the driving mechanism, the pressing plate 2 will drive the telescopic pipe 502 to continuously rotate on the top of the grain. Because the grain decays, the density of this area will decrease, and the entire vertical grain pile, especially the grain located above the decaying area, is prone to depression. In this way, the telescopic pipe 502 can move downward by means of the second spring 503, so as to locate the decaying area.

[0030] Please refer to Figure 4 , the downward detection mechanism further includes a connecting rod 507 fixedly connected to the telescopic pipe 502; the first U-shaped rod 506 is fixedly installed on the connecting rod 507, and a first blocking block 509 is fixedly installed at its bottom; the driving frame 505 is located below the first U-shaped rod 506 and is connected to the installation box 304 through the fourth spring; the driving bracket 504 is fixedly installed on the driving frame 505, and a first gear 315 is engaged thereon. The first gear 315 is fixedly connected to the switching valve 312.

[0031] When the telescopic pipe 502 encounters a rotting area of the grain, the telescopic pipe 502 will move downward under the action of the second spring 503 and insert into the grain pile. This can prevent the rotation of the pressing plate 2. Even if water flows through the impeller 306, the impeller 306 will not drive the pressing plate 2 and will not cause damage to the impeller 306. Moreover, it can drive the connecting rod 507 to pull the first U-shaped rod 506. In this way, the first U-shaped rod 506 will not only cancel the blocking of the wrapping mechanism by the first sealing plate, but also cause the driving frame 505 and the driving bracket 504 to move downward. This can act on the first gear 315 and make the first gear 315 rotate. The rotation of the first gear 315 will cause the switching valve 312 to switch the pipeline. In this way, the water source pumped by the water pump 302 will flow from the first connecting pipe 303 to the fourth connecting pipe 308, and then be transported to the inside of the installation box 304 through the rotating pipe 313 and the sixth connecting pipe 314. This can fill the installation box 304 with water. Since the first blocking block 509 opens the corresponding wrapping mechanism, the water source will act on the wrapping mechanism, and the wrapping mechanism will move downward until the real rotting area.

[0032] Please refer to Figure 5 and Figure 6 The wrapping mechanism includes a fixed disk 508 fixedly connected to the positioning pipe 501. The fixed disk 508 is inserted into the first blocking block 509. The bottom of the fixed disk 508 is fixedly connected to the corrugated pipe 510. A fifth spring is fixedly connected inside the fixed disk 508 and is fixedly connected to the corrugated pipe 510; The sliding plate is fixedly installed on the corrugated pipe 510 and is fixedly connected to the telescopic pipe 502.

[0033] The unfolding assembly includes a positioning plate 513 fixedly connected to the sliding plate; The mounting frame 517 is fixedly installed at the bottom of the positioning plate 513, on which a worm 516 is rotatably installed, and a worm gear 514 is rotatably installed on its surface. The worm gear 514 meshes with the worm 516; The rotating plate 515 is fixedly installed on the worm gear 514 and is fixedly connected to the arc-shaped cover 512; The unfolding assembly also includes a limiting pipe 518 fixedly connected to the mounting frame 517; The sliding pipe 519 is slidably installed inside the limiting pipe 518, and its top is connected to the mounting frame 517 through a third spring 520; The driving column 521 is fixedly installed at the bottom end of the worm 516, and a first track groove 523 is formed on its surface; One end of the driving block 522 is fixedly connected to the sliding pipe 519, and the other end is located inside the first track groove 523.

[0034] When the water source flushes into the fixed plate 508, the water source will enter the corrugated pipe 510. Since the corrugated pipe 510 is telescopic, under the action of the water source, the corrugated pipe 510 will continuously move downward until it moves to the rotted area. Since the sliding pipe 519 is the first to contact the rotted area, when the sliding pipe 519 touches the rotted area, the extrusion force of the grain on the bottom end of the sliding pipe 519 will be lost. Thus, under the action of the third spring 520, it will quickly move downward. The downward movement of the sliding pipe 519 will cause the driving block 522 to drive the driving column 521 to rotate, thereby causing the worm 516 to rotate. The worm 516 causes the worm gear 514 to rotate. In this way, the first gear 315 will drive the rotating plate 515 to rotate, causing the arc-shaped cover 512 to unfold. Since the arc-shaped cover 512 is connected to the positioning plate 513 through the heat-insulating soft layer 511, the heat-insulating soft layer 511 has a certain hardness and supportiveness, but it can be bent after being pressed and will automatically recover when not pressed. In this way, it will not affect the unfolding of the rotating plate 515. The corrugated pipe 510 will also drive the sliding pipe 519 to move downward. Since the grain in the lower layer of the rotted area is not affected much and has a high density, the sliding pipe 519 cannot directly move downward and is thus squeezed. In this way, the rotating plate 515 rotates back, causing the two arc-shaped covers 512 to fit together. With the heat-insulating soft layer 511, the grain in the rotted area can be well wrapped. And generally, the rotted area is a small area with a certain height and width. The downward movement distance of the sliding pipe 519 will be affected by the height. The more the downward movement distance, the larger the unfolding angle of the arc-shaped cover 512, so as to isolate the rotted area in a large range. In this way, it can effectively isolate the corresponding grain according to the situation of grain rot.

[0035] Please refer to Figure 3 A third connecting pipe 307 is fixedly installed on the fourth connecting pipe 308. The third connecting pipe 307 is communicated with the second connecting pipe 305. A temperature-controlled one-way valve is installed inside the third connecting pipe 307. The temperature-controlled one-way valve is closed when the temperature exceeds the threshold value and the water source cannot pass through it. When the temperature is lower than the threshold value, it belongs to a normal one-way valve. In this way, when the temperature controller makes the water pump 302 work, the water flow cannot pass through the third connecting pipe 307.

[0036] When the arc-shaped cover 512 wraps the rotted grain, since the arc-shaped cover 512 and the heat-insulating soft layer 511 can isolate heat, the dissipation of the heat source is reduced in this way. The internal air circulation in the granary can cool it down. Thus, the temperature-controlled one-way valve is opened. At this time, the fifth spring inside the corrugated pipe 510 will cause the corrugated pipe 510 to discharge the water source for recycling, so that the rotted grain returns to the telescopic pipe 502, which is convenient for subsequent staff to take out. And when the arc-shaped cover 512 moves upward, since the surrounding grain always acts on the arc-shaped cover 512, the arc-shaped cover 512 cannot be opened and can only move into the telescopic pipe 502 to be stored.

[0037] Please refer to Figure 8, a lifting mechanism is provided in the storage bin 1; the lifting mechanism includes a fixed pipe 402 fixedly connected to the storage bin 1; a sliding rod 405 is slidably installed inside the fixed pipe 402 and is connected to the fixed pipe 402 through a first spring 404, and its bottom end is fixedly connected to the driving disk 310 and the fixed disk 508; a permanent magnet 403 is fixedly installed between the two fixed pipes 402; a temperature-controlled electromagnet 401 is fixedly installed on the fourth connecting pipe 308.

[0038] When the temperature reaches the threshold value, the temperature-controlled electromagnet 401 is energized, so that it magnetically attracts the permanent magnet 403, and the temperature required by the temperature-controlled electromagnet 401 is lower than that of the temperature-controlled one-way valve and the temperature controller. In this way, when the grain in the storage bin 1 continuously increases, the grain presses the pressing plate 2, and the pressing plate 2 presses the first spring 404. The first spring 404 reacts to make the pressing plate 2 press the grain, enabling the grain to be stacked stably, compressing the gaps between the grains, and reducing the probability of grain rot. When the temperature of the grain pile rises to the threshold value of the temperature-controlled electromagnet 401, the temperature-controlled electromagnet 401 will be attracted by magnetic force, prompting the pressing plate 2 to move upward, so that the grain is no longer pressed, and the gaps between the grains can be released. And an air flow internal circulation device is provided in the granary, which can promote the air flow, so that the local heat can be dissipated, avoiding the occurrence of heat accumulation, and thus avoiding the grain rot caused by too high temperature at a certain place.

[0039] Please refer to Figure 11 , an exhaust pipe 605 is fixedly installed at the top of the storage bin 1. A cavity is provided in the inner wall of the exhaust pipe 605, and beeswax is filled in the cavity; a second U-shaped rod 603 is slidably connected to the exhaust pipe 605, and a second sealing plate 604 is fixedly installed on the second U-shaped rod 603, and the second sealing plate 604 is inserted into the exhaust pipe 605; the top of the exhaust pipe 605 is fixedly connected to a flow dividing block 601, and a second track groove 602 is provided inside the flow dividing block 601, and lime powder is smeared on the inner wall of the second track groove 602.

[0040] When the temperature in the storage bin 1 is too high and the air pressure is too high, the temperature will melt the beeswax, and the air pressure will cause the second sealing plate 604 to move upward. In this way, the second sealing plate 604 will move into the flow dividing block 601, so that the exhaust pipe 605 is connected to the second track groove 602, enabling the air flow to be discharged. Since the second track groove 602 can buffer the gas discharge, preventing the gas from being discharged too fast to form negative pressure to adsorb the grain and discharge it, and the lime powder is provided to dry the discharged gas, avoiding the presence of moisture in the gas, which causes the moisture to adhere to the second track groove 602 to form water droplets and drip, polluting the grain.

[0041] Working principle: When filling the storage bin 1 with grains, the grains are transported from the top to form a grain pile. Due to the uneven density inside the grain pile, affected by factors such as gravity and particle stacking state at different positions, there will be situations where the air circulation in the high-density area is blocked, heat and moisture accumulate, and the moisture of the grains in the low-density area is lost too quickly. When the grain pile accumulates to a certain height, the grain pile presses against the pressing plate 2, and the pressing plate 2 reversely presses against the grain pile under the action of its own downward pressing mechanism. Through this pressing, the grain pile can be stacked stably, ensuring uniform gaps between the grains and reducing the probability of grain rot due to local environmental problems.

[0042] As the situation in the storage bin changes, when the temperature sensor detects that the temperature of the grain pile rises and reaches the threshold of the temperature control electromagnet 401, the temperature control electromagnet 401 is energized and magnetically attracted to the permanent magnet 403, prompting the pressing plate 2 to move upward. At this time, the pressing force of the pressing plate 2 on the grains decreases, and the gaps between the grains are released. The air flow internal circulation device installed in the granary can promote air flow, dissipate local heat, and prevent grain rot caused by heat accumulation.

[0043] If the temperature continues to rise and reaches the preset value of the temperature controller, the temperature controller controls the water pump 302 to start. The water pump 302 pumps the water source in the storage box 301 into the first connecting pipe 303, and the water flows back to the storage box 301 through the switching valve 312, the fifth connecting pipe 309, the driving disk 310, and the second connecting pipe 305. During this process, the water flow drives the impeller 306 to rotate, and then drives the rotating pipe 313 to rotate, causing the pressing plate 2 to rotate and driving the downward probing mechanism in the installation box 304 to rotate. The telescopic pipe 502 in the downward probing mechanism slides in the positioning pipe 501 and rotates on the top of the grains by means of the elastic force of the second spring 503. When encountering an area with a density decrease caused by grain rot, the telescopic pipe 502 will move downward under the action of the second spring 503 and insert into the grain pile, blocking the rotation of the pressing plate 2. At the same time, the telescopic pipe 502 drives the connecting rod 507 to pull the first U-shaped rod 506, and the first U-shaped rod 506 causes the first blocking block 509 to cancel the blocking of the wrapping mechanism. It also drives the driving frame 505 and the driving frame 504 to move downward, driving the first gear 315 to rotate, causing the switching valve 312 to switch the pipeline, and the water source pumped by the water pump 302 is transported to the inside of the installation box 304 through the first connecting pipe 303, the fourth connecting pipe 308, the rotating pipe 313, and the sixth connecting pipe 314.

[0044] After the water source enters the installation box 304, it flows into the corrugated pipe 510 of the wrapping mechanism, causing the corrugated pipe 510 to move downward; when the sliding pipe 519 touches the rotten area and loses the extrusion pressure of the grain, it quickly moves downward under the action of the third spring 520, driving the driving block 522 to drive the driving column 521 to rotate, causing the worm 516 to rotate, and then causing the worm gear 514 to rotate, driving the rotating plate 515 to rotate, and causing the arc-shaped cover 512 to unfold; as the corrugated pipe 510 continues to move downward, the sliding pipe 519 is squeezed by the dense grain in the lower layer, the rotating plate 515 rotates back, and the two arc-shaped covers 512 fit together, and with the heat-insulating soft layer 511, the grain in the rotten area is wrapped up.

[0045] After the arc-shaped cover 512 wraps the rotten grain, the heat source emission is reduced, and the internal air circulation in the granary cools it down; when the temperature drops to the threshold value at which the temperature control one-way valve opens, the fifth spring inside the corrugated pipe 510 causes the corrugated pipe 510 to drain the water source for recycling, and the rotten grain returns to the telescopic pipe 502, facilitating subsequent removal by the staff; when the arc-shaped cover 512 moves upward, it cannot be opened due to the surrounding grain and can only move into the telescopic pipe 502 to be stored.

[0046] When the temperature in the storage bin 1 is too high and the air pressure is too strong, the temperature melts the beeswax in the inner cavity of the inner wall of the exhaust pipe 605, and the air pressure causes the second sealing plate 604 on the second U-shaped rod 603 to move upward into the flow dividing block 601, and the exhaust pipe 605 is connected to the second track groove 602, and the air flow is discharged; the second track groove 602 can buffer the gas discharge to avoid forming negative pressure to suck out the grain, and the lime powder coated on its inner wall can dry the discharged gas to prevent moisture from contaminating the grain.

[0047] The above describes the embodiments of the present invention, but these embodiments are not limited to the above specific implementation manners. The above specific implementation manners are only illustrative and not restrictive. Under the inspiration of this embodiment, those of ordinary skill in the art can also make many forms, all of which fall within the protection scope of this embodiment.
