Description

Technical Field

[0001] The present application relates to the field of grain storage buildings, and in particular to a multi-layer grain storage silo. Background Art

[0002] A granary is a special building for storing grain, generally used to store large amounts of grain.

[0003] A Chinese patent with announcement number CN105612943A discloses a grain storage bin, including a bin body and a bracket. The bin body is arranged on the bracket. A grain inlet leading to the grain storage bin is opened at the top of the bin body, and a grain outlet leading to the grain storage bin is opened at the bottom of the bin body. Pulleys are also provided at each end corner of the bottom of the bracket.

[0004] However, the grain storage silo can only take out grain from the bottom of the silo, and all the old grain in the silo needs to be removed before new grain can be input into the silo for storage. It is also difficult to store multiple batches or multiple types of grain at the same time.

[0005] In view of this, it is necessary to provide a multi-layer grain storage silo. Utility Model Content

[0006] In order to solve the problem that grain storage silos are difficult to store multiple batches or multiple types of grain at the same time, the present application provides a multi-layer grain storage silo.

[0007] The present application provides a multi-layer grain storage silo, which adopts the following technical solution: a silo body and multi-layer partitions, wherein the multi-layer partitions are arranged from top to bottom inside the silo body and divide the silo body into multiple layers of grain storage spaces arranged from top to bottom and suitable for storing grain, and a plurality of grain outlets are provided on the side wall of the silo body, and the grain outlets correspond one-to-one to the grain storage spaces; a top-layer grain inlet is provided on the top of the silo body, and each of the partitions is provided with a grain inlet leading to the grain storage space of the next layer, and each of the grain inlets is provided with a valve, so that the grain can fall into the interior of the silo body from the top-layer grain inlet, and can continue to fall through the grain inlet when the valve in the grain inlet is opened.

[0008] By adopting the above technical scheme, when there is no grain stored in the silo, the valves in each grain inlet can be opened first, and then the first batch or type of grain can be input into the silo from the top grain inlet, and the batch or type of grain will fall directly into the grain storage space at the bottom layer. After the grain storage space at the bottom layer is filled with the first batch or type of grain, the valve corresponding to the grain storage space at the bottom layer is closed, so that the grain storage space at the bottom layer can be sealed, and then the second batch or type of grain can be continuously input into the silo from the top grain inlet, and the batch or type of grain will fall directly into the second layer (the second layer counted from bottom to top) of the grain storage space. After the grain storage space is full, the corresponding valve is closed and the third batch or type of grain is continuously input. By repeating the above operation, different batches or types of grain can be stored separately; when different batches or types of grain are stored in the silo, the grain output of the batch or type of grain can be realized by opening the grain output port corresponding to the grain storage space storing the required batch or type of grain.

[0009] Specifically, a side grain inlet is opened on the side wall of the grain storage space other than the grain storage space on the top layer, and the grain outlets of the grain storage space other than the grain storage space on the bottom layer can be connected with the side grain inlet of the grain storage space on the next layer.

[0010] By adopting the above technical scheme, when the grain in a certain layer of grain storage space is all taken out and is in an empty state, while the grain storage spaces on other layers higher than the layer are still in a full state, the grain storage space on the upper layer can be placed in an empty state by connecting the side grain inlet of the empty grain storage space with the grain outlet of the full grain storage space on the upper layer, while the originally empty grain storage space becomes full. By repeating the above operation, it can be ensured that no matter which layer of grain storage space of the multi-layer grain storage silo the grain is taken out, the grain storage space on the top layer can be placed in an empty state through the above process, so that grain can be replenished into the grain storage space on the top layer through the grain inlet on the top layer, thereby realizing the replenishment operation of the multi-layer grain storage silo.

[0011] Furthermore, a grain outlet valve is provided at the grain outlet, and the grain outlet valve includes a rotating valve core, and a grain passage hole is provided on the rotating valve core, and the grain passage hole includes a grain passing port and a grain discharge port, and a closed section is also formed on the surface of the rotating valve core;

[0012] When the rotary valve core rotates until the grain passing port is connected to the grain outlet and the grain discharge port is connected to the side grain inlet, the grain in the grain storage space of the upper layer can pass through the rotary valve core and enter the grain storage space of the lower layer;

[0013] When the rotary valve core rotates until the grain discharge port is connected with the grain discharge port and the grain passing port is connected with the outside, the closing section can abut against the side grain inlet and close the side grain inlet, and the grain in the grain storage space on the upper layer can pass through the rotary valve core and enter the outside;

[0014] When the rotary valve core rotates to the closing section and abuts against the grain outlet and the side grain inlet at the same time, the side grain inlet and the grain outlet can be closed.

[0015] By adopting the above technical scheme, the rotating valve core is adjusted so that the closing section abuts against the grain outlet and the side grain inlet at the same time, so that the side grain inlet and the grain outlet can be closed; the rotating valve core is adjusted so that the grain outlet is connected to the grain outlet and the grain release port is connected to the side grain inlet at the same time, so that the grain in the grain storage space connected to the grain outlet can fall into the grain storage space connected to the side grain inlet; the rotating valve core is adjusted so that the grain release port is connected to the grain outlet and the grain outlet is connected to the outside at the same time, so that the grain in the grain storage space connected to the grain outlet can be released from the grain outlet valve, so that the grain storage space can be closed, the grain can be released, and the grain storage space can be replaced by the lower grain storage space by adjusting the state of the rotating valve core in the grain outlet valve.

[0016] Furthermore, the rotating valve core is cylindrical, and the rotating valve core uses its own central axis as the rotation axis. The grain passing port, the grain releasing port and the closed section are formed on the cylindrical surface of the rotating valve core around its own circumference, and the outer surface of the rotating valve core except the grain passing port and the grain releasing port is wrapped with a deformation layer.

[0017] By adopting the above technical scheme, by rotating the rotary valve core to rotate it around its own central axis, the positional relationship between the grain port, the grain discharge port and the closed section and the grain outlet and the side grain inlet can be adjusted, so that the grain outlet valve can be switched back and forth between the three states of closing, opening to release grain and replacing grain in the upper grain storage space into the lower grain storage space; when grains fall between the rotary valve core and the inner wall of the grain outlet valve, the deformation layer will abut against these grains and deform, so as to half-wrap these grains in the deformation layer, so that these grains are not easily crushed by the rotary valve core.

[0018] Specifically, the plurality of grain outlets are staggered in the vertical direction on the side wall of the bin body.

[0019] By adopting the above technical solution, when discharging grain from multiple grain outlets at the same time, it can be ensured that different batches or types of grain discharged from each grain outlet will not be mixed with each other, thereby improving the grain discharging efficiency.

[0020] Specifically, the grain outlet corresponding to the grain storage space is opened at the bottom of the side wall of the grain storage space, and the partition is inclined upward from the direction close to the grain outlet on the same layer to the direction away from the grain outlet.

[0021] By adopting the above technical solution, the grain in the grain storage space can flow along the inclined partition to the grain outlet when releasing the grain, thereby avoiding the situation where a lot of grain remains in the grain storage space far away from the grain outlet.

[0022] Specifically, it also includes a controller. Temperature sensors and humidity sensors are provided on the inner walls of the grain storage space on each layer. Each temperature sensor and humidity sensor is electrically connected to the controller and can send detection results of the temperature and humidity in the grain storage space to the controller.

[0023] By adopting the above technical solution, the temperature sensor can detect the temperature in each layer of the grain storage space, the humidity sensor can detect the humidity in each layer of the grain storage space, and feed back the detection data to the controller.

[0024] Furthermore, it also includes a ventilation plate and a cooling and dehumidifying device, the ventilation plate is laid on the top surface of each of the partitions to form a ventilation gap therebetween, and a number of fish-scale holes are provided on the surface of the ventilation plate, the air outlet of the cooling and dehumidifying device is connected to the ventilation gap, and exhaust holes are also provided on the side walls of each of the grain storage spaces, and each of the exhaust holes is connected to the air inlet of the cooling and dehumidifying device, the controller is electrically connected to the cooling and dehumidifying device, and can control the opening and closing of the cooling and dehumidifying device according to the received detection results.

[0025] By adopting the above technical scheme, when the controller finds that any one of the grain temperature or humidity in the received detection data exceeds the range required for grain storage, the controller will control the cooling and dehumidification device to turn on. The cooling and dehumidification device can blow cold air into the grain storage space on each layer through the ventilation duct, while drawing the gas in each grain storage space back from the exhaust hole, thereby realizing the circulation cooling of the gas, and can condense and dehumidify the moisture contained in the gas while cooling the gas, thereby restoring the temperature and humidity of the grain in the grain storage space to within the range required for grain storage; when the controller finds that the grain temperature and humidity in the received detection data are both maintained within the range required for grain storage, the controller will control the cooling and dehumidification device to turn off, thereby realizing automatic adjustment of the grain condition in the grain storage space.

[0026] In summary, this application includes the following beneficial technical effects:

[0027] A silo body and multi-layer partitions are provided, wherein the multi-layer partitions are provided inside the silo body from top to bottom, and divide the silo body into multiple layers of grain storage spaces arranged from top to bottom and suitable for storing grains, and a plurality of grain outlets are provided on the side walls of the silo body, and the grain outlets correspond to the grain storage spaces one by one; a top-layer grain inlet is provided on the top of the silo body, and a grain inlet leading to the next layer of grain storage space is provided in the middle of each partition, and a valve is provided in each grain inlet, so that grains can fall into the interior of the silo body from the top-layer grain inlet, and can continue to fall through the grain inlet when the valve in the grain inlet is opened, so that different batches or types of grains can be separately stored in different layers of grain storage space through the cooperation of the top-layer grain inlet and the valves on each layer; when different batches or types of grains are stored in the silo body, the grain outlet corresponding to the grain storage space storing the required batches or types of grains can be opened, so that the grains of the batches or types can be separately discharged.

DETAILED DESCRIPTION

[0035] Figure 1 This is a front view of an embodiment of a multi-layer grain storage silo of the present application. Figure 2 is along Figure 1 A schematic cross-sectional view of a multi-layer grain storage silo taken along the axis of the silo body, wherein only one multi-layer grain storage silo is shown. Figure 1 and Figure 2 A multi-layer grain storage silo provided in the present application includes: a silo body 1, with multiple top-level grain inlets 15, for example, 5, opened on the top of the silo body 1; multi-layer partitions 2 are arranged inside the silo body 1 from top to bottom, and divide the silo body 1 into multiple layers of grain storage spaces 11 arranged from top to bottom and suitable for storing grain. These partitions 2 can be cast by concrete slipforms, and each partition 2 is provided with a grain inlet 21 leading to the next layer of grain storage space 11, and each grain inlet 21 is provided with a valve 211. In one embodiment of the present application, the valve 211 can be an electrically controlled valve, and grain can fall into the interior of the silo body 1 from the top-level grain inlet 15, and can continue to fall through the grain inlet 21 when the valve 211 in the grain inlet 21 is opened.

[0036] According to the above design, when there is no grain stored in the silo 1, the worker can first open the valve 211 in each grain inlet 21, and then input the first batch or type of grain into the silo 1 from the top-level grain inlet 15, and the batch or type of grain will fall directly into the grain storage space 11 on the bottom layer. After the grain storage space 11 on the bottom layer is filled with the first batch or type of grain, the valve 211 corresponding to the grain storage space 11 on the bottom layer is closed, so as to seal the grain storage space 11 on the bottom layer, and then continue to input the second batch or type of grain into the silo 1 from the top-level grain inlet 15, and the batch or type of grain will fall directly into the second-layer grain storage space 11. After the grain storage space 11 is full, the corresponding valve is closed and the third batch or type of grain is continuously input. By repeating the above operation, different batches or types of grain can be stored separately.

[0037] Preferably, five pressure-reducing pipes (not shown in the figure) for transporting grain can be arranged at the five top-level grain inlets 15. The pressure-reducing pipes can sequentially pass through the corresponding grain inlets 21 arranged on each layer of the partition 2 and extend into the grain storage space 11 on the bottom layer. An electric-controlled valve is provided at the junction of the pipe body of the pressure-reducing pipe and each layer of the partition 2.

[0038] Through the above design, when it is necessary to store grain in the grain storage space 11 of the first layer, it is only necessary to open the electric control valve at each layer of the partition 2, and the grain can fall into the grain storage space 11 of the first layer along the pressure reducing pipe; after the grain storage space 11 of the first layer is full, it is only necessary to close the electric control valve at the first layer of the partition 2, and the grain can be transported to the grain storage space 11 of the second layer through the pressure reducing pipe. After the grain storage space 11 of the second layer is full, the electric control valve at the second layer of the partition 2 is closed again. By operating in this way in sequence, all the grain storage spaces 11 of each layer can be filled, thereby realizing separate storage of grain; when it is necessary to transport the grain in the upper grain storage space 11 to the lower grain storage space 11, it is only necessary to open the electric control valve arranged at the partition 2 between the two layers of grain storage space 11, and the grain layer can be changed through the pressure reducing pipe.

[0039] See also Figure 1 and Figure 2 A plurality of grain outlets 12 are also provided on the side wall of the silo 1, and the grain outlets 12 correspond to the grain storage spaces 11 one by one, so that when different batches or types of grain are stored in the silo 1, by opening the grain outlet 12 corresponding to the grain storage space 11 storing the required batch or type of grain, the grain of the batch or type can be discharged separately; the plurality of grain outlets 12 are staggered in the vertical direction on the side wall of the silo 1, so that when the plurality of grain outlets 12 are opened at the same time to discharge the grain, it can be ensured that the grains of different batches or types discharged from the grain outlets 12 will not be mixed with each other, thereby improving the grain discharge efficiency.

[0040] Specifically, the grain outlet 12 corresponding to the grain storage space 11 is opened at the bottom of the side wall of the grain storage space 11, and the partition 2 in each grain storage space 11 is inclined upward from the grain outlet 12 close to the same layer to the direction away from the grain outlet 12, so that when the grain is released, the grain in the grain storage space 11 can flow along the inclined partition 2 to the grain outlet 12, thereby avoiding the situation where there is a lot of grain remaining in the grain storage space 11 far away from the grain outlet 12.

[0041] Figure 3 This is a three-dimensional diagram of another embodiment of a multi-layer grain storage silo of the present application. Figure 4 1 is a top view of another embodiment of a multi-layer grain storage silo of the present application. Figure 3 and Figure 4 In another embodiment of the present application, a top-layer grain inlet 15 is provided on the top of the silo body 1 so that grain can be input into the silo body 1 through the top-layer grain inlet 15, and a plurality of grain outlet valves 13 are provided on the side wall of the silo body 1 so that the grain outlet valves 13 can be used to control the grain outlet of a multi-layer grain storage silo.

[0042] Figure 5 is along Figure 4 Schematic cross-sectional view taken along the AA direction, see Figure 3 and Figure 5 A side grain inlet 111 may be opened on the side wall of the grain storage space 11 other than the grain storage space 11 on the top layer, and the grain outlets 12 of the grain storage space 11 other than the grain storage space 11 on the bottom layer may be connected to the side grain inlet 111 of the grain storage space 11 on the next layer. With the above design, when all the grain in the grain storage space 11 of a certain layer is taken out and is in an empty state, while the grain storage spaces 11 on other layers higher than this layer are still in a full state, the side grain inlet 111 of the empty grain storage space 11 can be connected with the grain outlet 12 of the full grain storage space 11 of the upper layer, so that the grain storage space 11 on the upper layer can be put into an empty state, and the originally empty grain storage space 11 can be turned into a full state. By repeating the above operation, it can be ensured that no matter which layer of grain storage space 11 of the multi-layer grain storage silo is taken out, the grain storage space 11 on the top layer can be put into an empty state through the above process, so that grain can be replenished into the grain storage space 11 on the top layer through the top grain inlet 15, thereby realizing the replenishment operation of the multi-layer grain storage silo.

[0043] Figure 6 yes Figure 5 Schematic enlargement of area B in FIG, showing the rotating valve core. Figure 5 and Figure 6The grain outlet valve 13 is arranged at the grain outlet 12, and the grain outlet valve 13 includes a rotary valve core 14, a grain passage hole 141 is opened on the rotary valve core 14, and the grain passage hole 141 includes a grain passing port 1411 and a grain discharge port 1412, and a closed section 142 is formed on the surface of the rotary valve core 14; when the rotary valve core 14 rotates to the grain passing port 1411 to communicate with the grain outlet 12 and the grain discharge port 1412 is connected to the side grain inlet 111, the grain in the upper grain storage space 11 can pass through the rotary valve core 14 into the lower grain storage space 11; when the rotary valve core 14 rotates to the grain discharge port 1412 to communicate with the grain outlet 12 When the grain port 1411 is connected to the outside, the closing section 142 can abut against the side grain inlet 111 and close the side grain inlet 111, and the grain in the upper grain storage space 11 can pass through the rotating valve core 14 and enter the outside; when the rotating valve core 14 rotates to the closing section 142 and abuts against the grain outlet 12 and the side grain inlet 111 at the same time, the closing section 142 can close the side grain inlet 111 and the grain outlet 12, so that the grain storage space 11 can be closed, the grain can be released and the grain in the upper grain storage space 11 can be replaced by the lower grain storage space 11 by adjusting the state of the rotating valve core 14 in the grain outlet valve 13.

[0044] See also Figure 5 and Figure 6 The rotary valve core 14 can be set to a cylindrical shape. The rotary valve core 14 uses its own central axis as the rotation axis. A grain passing port 1411, a grain discharge port 1412 and a closed section 142 are formed on the cylindrical surface of the rotary valve core 14 around its own circumference. The rotating shafts on both sides of the rotary valve core 14 are connected to the outer wall of the bin body 1 through bearing seats. The rotary valve core 14 is also connected to the motor transmission so that the rotary valve core 14 can be rotated around its own central axis by the motor to adjust the positional relationship between the grain passing port 1411, the grain discharge port 1412 and the closed section 142 and the grain outlet 12 and the side grain inlet 111, so that the grain outlet valve 13 can be switched back and forth between the three states of closing, opening to release grain and replacing the grain in the upper grain storage space 11 with the lower grain storage space 11.

[0045] Specifically, a deformation layer (not shown in the figure) may be wrapped on the outer surface of the rotary valve core 14 except for the grain port 1411 and the grain discharge port 1412. The deformation layer may be a rubber layer. When grains fall between the rotary valve core 14 and the inner wall of the grain discharge valve 13, the deformation layer will abut against the grains and deform, so as to half-wrap the grains in the deformation layer, thereby making it difficult for the grains to be crushed by the rotary valve core 14. The deformation layer can also prevent the rotating shaft of the rotary valve core 14 from bending and being damaged due to grains getting stuck between the rotary valve core 14 and the inner wall of the grain discharge valve 13, or prevent the motor from being burned out due to excessive load due to grains getting stuck in the rotary valve core 14 in the grain discharge valve 13.

[0046] See also Figure 5 and Figure 6 A multi-layer grain storage silo further includes a controller (not shown in the figure), a ventilation plate 3 and a cooling and dehumidifying device 4. A temperature sensor 112 and a humidity sensor 113 are provided on the inner wall of each layer of grain storage space 11. The temperature sensor 112 can detect the temperature in each layer of grain storage space 11, and the humidity sensor 113 can detect the humidity in each layer of grain storage space 11. Each temperature sensor 112 and humidity sensor 113 is electrically connected to the controller and can send the detection results of the temperature and humidity in the grain storage space 11 to the controller; A ventilation plate 3 is laid on the top surface of each partition 2 and a ventilation gap 32 is formed therebetween, and a number of fish-scale holes 31 are provided on the surface of the ventilation plate 3; the cooling and dehumidifying device 4 can be a special air conditioner for a grain depot with a dehumidification function, and the air outlet of the cooling and dehumidifying device 4 is connected to the ventilation gap 32, and exhaust holes 16 are also provided on the side walls of each grain storage space 11, and each exhaust hole 16 is connected to the air inlet of the cooling and dehumidifying device 4, and the controller is electrically connected to the cooling and dehumidifying device 4, and can control the opening and closing of the cooling and dehumidifying device 4 according to the received detection results.

[0047] Through the above design, when the controller finds that any one of the grain temperature or humidity in the received detection data exceeds the range required for grain storage, the controller will control the cooling and dehumidification device 4 to turn on. The cooling and dehumidification device 4 can blow cold air into each layer of the grain storage space 11 through the ventilation duct, while drawing the gas in each grain storage space 11 back from the exhaust hole 16, thereby realizing the circulation cooling of the gas, and can condense and dehumidify the moisture contained in the gas while cooling the gas, so that the temperature and humidity of the grain in the grain storage space 11 can be restored to the range required for grain storage; when the controller finds that the grain temperature and humidity in the received detection data are maintained within the range required for grain storage, the controller will control the cooling and dehumidification device 4 to turn off, thereby realizing automatic adjustment of the grain condition in the grain storage space 11.

[0048] Preferably, the fish scale holes 31 on the ventilation plate 3 can be arranged so that the air outlet of each fish scale hole 31 faces the direction of the grain outlet 12 on the same layer, so that the airflow blown out from the fish scale holes 31 can blow the grain toward the grain outlet 12, thereby avoiding the situation in which there is a lot of grain remaining in the grain storage space 11 far away from the grain outlet 12 after the grain is released.

[0049] The working principle of a multi-layer grain storage silo in the present application when in use is as follows:

[0050] The storage device comprises a storage body 1 and a multi-layer partition 2, wherein the multi-layer partition 2 is arranged inside the storage body 1 from top to bottom, and divides the storage body 1 into multiple layers of grain storage spaces 11 arranged from top to bottom, which are suitable for storing grain. A plurality of grain outlets 12 are provided on the side wall of the storage body 1, and the grain outlets 12 correspond to the grain storage spaces 11 one by one. A top-layer grain inlet 15 is provided on the top of the storage body 1, and a grain inlet 21 leading to the next-layer grain storage space 11 is provided in the middle of each partition 2, and each grain inlet 21 is provided with a valve, so that grain can be discharged from the top-layer grain inlet 15 falls into the interior of the silo 1, and can continue to fall through the grain inlet 21 when the valve in the grain inlet 21 is opened, so that different batches or types of grain can be stored separately in the grain storage space 11 of different layers through the cooperation of the top grain inlet 15 and the valves of each layer; when different batches or types of grain are stored in the silo 1, the grain of the batch or type can be discharged separately by opening the grain outlet 12 corresponding to the grain storage space 11 storing the required batch or type of grain.

[0051] It should be noted that, in this application, directional terms such as "first layer" and "second layer" are counted from the direction close to the ground to the direction away from the ground. The above are all preferred embodiments of this application, and the protection scope of this application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of this application should be included in the protection scope of this application.
