Description

Technical Field

[0001] This utility model belongs to the field of grain storage and transportation technology, specifically relating to a vehicle-mounted intelligent grain transport warehouse. Background Technology

[0002] Food security storage is a global challenge. In recent years, with the continuous progress of agricultural science and technology, agricultural production has continued to increase steadily, and the amount of grain produced by farmers has also increased day by day. As a result, the problem of grain storage has become more and more obvious. Currently, after the grain is harvested in the fields, it is generally stored in a fixed container and transported in a unified manner, which requires the use of special grain warehouses.

[0003] Existing truck-mounted grain silos have a simple structure and can only store and transport grain. However, grain needs to undergo multiple processes before storage, such as screening, filtering impurities, drying, and pest control. The existing truck-mounted grain silos are simple in structure and lack the ability to process grain before storage. Grain needs to be processed by multiple different devices before storage and transportation, which greatly affects the processing speed and requires a lot of manpower, thus affecting the grain storage progress. Moreover, most existing grain silos are fixed to the truck body. The grain needs to be transported to a designated location by the truck body, then unloaded, and then returned to the field for storage. This method of grain transportation is not convenient for the unified transportation of large quantities of grain. It requires transportation every time it is full, which is not conducive to improving the efficiency of grain transportation and requires the truck body to frequently turn around, which is not conducive to the unified and efficient processing and transportation of grain.

The magnetic washing screen and the sieve are both hinged to the side wall of the feed cylinder by electric hinges. There are several magnetic washing screens and sieves, and they are arranged alternately. The magnetic washing screen is set horizontally, while the sieve is set at an angle. The upper part of both sides of the feed cylinder near the electric hinge has slots for impurities to pass through. The spiral tube is fixedly connected to the outside of the feed cylinder, and several slots communicate with the inside of the spiral tube.

[0009] Preferably, the spiral conveying mechanism includes a spiral conveyor belt, a rotating screen plate, and a drive motor.

[0025] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figures 1 to 8 The embodiments are described in detail below.

[0026] This embodiment provides a vehicle-mounted intelligent grain transport warehouse, as shown in the attached document. Figure 1-8As shown, the system includes a storage chamber 1 and a storage chamber 2. The storage chamber 1 can be fixedly installed on the vehicle body. As the vehicle body moves, the interior of the storage chamber 1 is equipped with a drying mechanism for dehydrating grain. The drying mechanism includes a drying drum 3 with an inverted cone-shaped bottom, heating belts 4, a first electric push rod 5, and a first sealing plate 6. The top of the drying drum 3 is fixedly connected to the inner top wall of the storage chamber 1, and its side is provided with ventilation holes 7. There are several ventilation holes 7 arranged in a ring array on the side of the drying drum 3, which allows water vapor during grain drying to dissipate outward, ensuring drying efficiency. There are several heating belts 4, all of which are fixedly installed in a ring on the outside of the drying drum 3. The heating belts 4 can heat the inside of the drying drum 3 to dry the grain inside. A grain outlet 8 for discharging grain is provided at the center of the bottom of the drying barrel 3. A first sealing plate 6 is sealed below the grain outlet 8 and connected to the end of the movable rod of the first electric push rod 5. The fixed rod part of the first electric push rod 5 is fixedly installed at the bottom of the side of the drying barrel 3, and the movable rod part passes through the side of the drying barrel 3. A slot is provided on the bottom side of the drying barrel 3 away from the first electric push rod 5, through which the first sealing plate 6 can pass. When the first electric push rod 5 pushes the first sealing plate 6 through the slot, the grain outlet 8 at the bottom of the drying barrel 3 can be opened, so that the grain can fall into the storage bin 2 below. When the movable rod of the first electric push rod 5 drives the first sealing plate 6 to retract inward, the grain outlet 8 can be closed, so that the filtered grain can be piled up inside the drying barrel 3 and dried.

[0027] The drying unit is equipped with a filtration mechanism for removing impurities from the grain. This filtration mechanism includes a grain inlet cylinder 9, a magnetic washing screen 10, a sieve 11, and a spiral tube 12. The grain inlet cylinder 9 is located inside the drying barrel 3 and corresponds to its axis. The top of the grain inlet cylinder 9 is fixedly connected to the inner top wall of the storage chamber 1, and a circular hole communicating with the grain inlet cylinder 9 is provided on the upper surface of the storage chamber 1. A funnel can be installed in the circular hole to facilitate the injection of grain into the grain inlet cylinder 9. Collected grain can be injected into the grain inlet cylinder 9 through the circular hole. The magnetic washing screen 10 and the sieve 11 are both hinged to the side wall of the grain inlet cylinder 9 via electric hinges. The number of magnetic washing screens 10 and sieves 11 is [missing information]. Several magnetic washing screens 10 and screens 11 are arranged alternately. The magnetic washing screens 10 are set horizontally, while the screens 11 are set at an angle. When the grain falls into the grain inlet hopper 9, it will first pass through the top magnetic washing screen 10, then fall onto the screen 11 below and roll down from the angled screen 11. It will then pass through the lower magnetic washing screen 10 again and continue to be screened by the screen 11. The magnetic washing screen 10 can adsorb metal substances in the grain and filter large particles, while the screen 11 can filter impurities such as sand in the grain. The arrangement of multiple magnetic washing screens 10 and screens 11 can fully filter the grain and ensure its purity.

[0028] Both sides of the feed hopper 9 are provided with slots 13 for impurities to pass through, located on the upper side near the electric hinge. The spiral tube 12 is fixedly connected to the outside of the feed hopper 9, and several slots 13 are connected to the inside of the spiral tube 12. After a period of filtration, some impurities will accumulate on the magnetic washing screen 10 and the screen 11. Therefore, by controlling the electric hinge to rotate the magnetic washing screen 10 and the screen 11 to an inclined state, the impurities on the magnetic washing screen 10 and the screen 11 can roll into their corresponding slots 13. This allows the impurities on multiple magnetic washing screens 10 and screens 11 to be stored in the spiral tube 12 and roll along the spiral tube 12 to the bottom. The impurities stored in the spiral tube 12 are cleaned regularly to ensure that the magnetic washing screen 10 and the screen 11 always have a good filtration effect.

[0029] A spiral conveyor mechanism is provided between the filtration mechanism and the drying mechanism. The spiral conveyor mechanism includes a spiral conveyor belt 14, a rotating screen plate 15, and a drive motor 16. The bottom end of the spiral conveyor belt 14 is fixedly connected to the upper surface of the rotating screen plate 15 and sleeved around the outside of the grain inlet hopper 9. A motor housing 17 for mounting the drive motor 16 is fixedly installed at the bottom inside the drying hopper 3. The drive motor 16 is fixedly installed inside the motor housing 17, and one end of its output shaft passes through the upper surface of the motor housing 17 and is connected to the rotating screen plate 15 via a spline. The surface of the rotating screen plate 15 has openings for the grain to pass through. The grain passes through the mesh of the rotating mesh plate 15 and falls into the bottom of the drying barrel 3. The drive motor 16 drives the rotating mesh plate 15 and the spiral conveyor belt 14 to rotate. When more filtered grain needs to be stored in the drying barrel 3, the spiral conveyor belt 14 is controlled to convey the grain upward, thereby pushing the grain at the bottom of the drying barrel 3 upward, leaving the bottom of the drying barrel 3 empty. This allows the grain in the grain feed cylinder 9 to continuously fall into the drying barrel 3 until the drying barrel 3 is full. Then, the heating belt 4 heats the inside of the drying barrel 3, thereby drying and dehydrating the grain inside.

[0030] After the grain is dehydrated, the first electric push rod 5 pushes the first sealing plate 6 to move, opening the grain outlet 8, so that the grain in the drying barrel 3 can fall downward into the storage chamber 2. At the same time, the spiral conveyor belt 14 can be controlled to convey downward, thereby accelerating the falling of the grain in the drying barrel 3 and allowing the grain to fall into the storage chamber 2 more quickly. After all the dehydrated grain of this batch has fallen into the storage chamber 2, the first electric push rod 5 is controlled to drive the first sealing plate 6 to reseal the grain outlet 8, and then grain is re-injected into the grain inlet 9 to continue filtering and drying the grain.

[0031] Storage chamber 2 is bolted to the lower surface of chamber body 1. The bottom end of the drying mechanism passes through the top of storage chamber 2 and communicates with its interior. A nitrogen filling mechanism for insecticidal purposes is provided on one side of the interior of storage chamber 2. The nitrogen filling mechanism includes a nitrogen storage chamber 18 and an air pump 19. A partition 20 is fixedly connected to one side of the interior of storage chamber 2, dividing storage chamber 2 into a grain storage chamber 21 and a nitrogen storage chamber 18. A grain discharge pipe is provided at the bottom of storage chamber 2, and a second electric push rod 23 is fixedly installed on the side of the grain discharge pipe. The movable part of the second electric push rod 23 passes through the interior of the grain discharge pipe and its end... A second sealing plate 24 is fixedly connected. The second electric push rod 23 drives the second sealing plate 24 to move, which can control the flow of the grain discharge pipe, thereby controlling the release and storage of grain. All the dehydrated grain is stored in the grain storage silo 21. The nitrogen storage silo 18 stores nitrogen. The air pump 19 is fixedly installed on the side of the partition 20 near the nitrogen storage silo 18, and the air inlet and outlet are respectively connected to the inside of the nitrogen storage silo 18 and the grain storage silo 21. The air pump 19 can draw the nitrogen in the nitrogen storage silo 18 into the grain storage silo 21, thereby killing insects in the grain and preventing insect damage during storage.

[0032] Both the drying unit and the storage chamber 2 are equipped with temperature monitoring mechanisms that can detect the temperature of the grain. The temperature detection mechanism is a temperature sensor 22. Temperature sensors 22 that can monitor the temperature of the grain inside are fixedly installed on the side of the drying barrel 3 and the storage chamber 2 near the grain storage chamber 21. The temperature sensor 22 on the side of the drying barrel 3 can monitor the internal heating temperature so that the control unit can dynamically adjust the temperature of the heating belt 4 to achieve a suitable temperature for dehydrating the grain. The temperature sensor 22 on the side of the storage chamber 2 can monitor the overall temperature of the grain inside the storage chamber 2 in real time. Since the grain may deteriorate and ferment due to moisture after being piled up, the overall temperature of the grain may rise. Therefore, the temperature sensor 22 on the side of the storage chamber 2 can monitor the temperature of the grain in real time so that the management personnel can know the status of the grain in time and avoid significant losses.

[0033] The drying mechanism, the filtering mechanism, and the spiral conveying mechanism are all in number, and the drying mechanism is fixedly arranged at equal intervals inside the silo 1. The upper surface of the storage silo 2 has a grain inlet that can communicate with the inside of the grain storage silo 21. The bottom ends of the drying mechanism are all inserted into the grain inlet. The arrangement of multiple drying mechanisms, filtering mechanisms, and spiral conveying mechanisms can facilitate the simultaneous processing of more grains, thereby accelerating the processing and storage efficiency of grains.

[0034] Heating band 4, first electric push rod 5, electric hinge, drive motor 16, air pump 19, temperature sensor 22 and second electric push rod 23 are all electrically connected to the external control unit and are all electrically connected to the external circuit through wires.

[0035] In summary, the operating steps for this vehicle-mounted intelligent grain transport silo are as follows:

[0036] 1. When grain is injected into multiple feed cylinders 9, it will first pass through the top magnetic washing screen 10, then fall onto the lower screen 11 and roll down from the inclined screen 11, pass through the lower magnetic washing screen 10 again and continue to be screened by the screen 11. The setting of multiple magnetic washing screens 10 and screens 11 can fully filter the grain and ensure the purity of the grain.

[0037] 2. Grain can pass through the grid of the rotating screen plate 15 and fall into the bottom of the drying barrel 3. The drive motor 16 drives the spiral conveyor belt 14 to convey it upward, pushing the grain at the bottom of the drying barrel 3 upward, leaving the bottom of the drying barrel 3 empty, so that the grain in the grain inlet 9 can continuously fall into the drying barrel 3 until the drying barrel 3 is full of grain. Then the heating belt 4 heats the inside of the drying barrel 3, thereby drying and dehydrating the grain inside.

[0038] 3. All the dehydrated grains are stored in the grain storage silo 21. The air pump 19 can draw nitrogen from the nitrogen storage silo 18 into the grain storage silo 21, which can kill insects in the grains and prevent insect damage during storage.

[0039] 4. The temperature sensor 22 installed on the side of the drying barrel 3 can monitor the internal heating temperature so that the control unit can dynamically adjust the temperature of the heating belt 4 to achieve a suitable temperature for dehydrating the grain. The temperature sensor 22 installed on the side of the storage chamber 2 can monitor the overall temperature of the grain in the storage chamber 2 in real time so that the management personnel can know the status of the grain in time and avoid significant losses.

[0040] The above description is only for illustrating the present utility model. It should be understood that the present utility model is not limited to the above embodiments, and various modifications that conform to the concept of the present utility model are within the protection scope of the present utility model.
