Description

TECHNICAL FIELD

[0001] The utility model belongs to grain storage technical field, concretely relates to an intelligent control device for grain storage loss reduction and dust reduction. BACKGROUND

[0002] In the process of grain falling from the top of the shallow circular silo or the vertical silo to the inside of the silo, since the grain is mixed with dust, straw and other impurities, and the shallow circular silo or the vertical silo is high and the grain falling distance is far, the first is that it will cause serious automatic classification phenomenon, resulting in uneven texture of the grain pile in the silo, and the impurities are concentrated and accumulated in a specific area, which not only affects the safety of the grain during static storage, but also causes significant differences between the sampling inspection data of the impurity accumulation area and the overall quality of the grain; the second is that the grain is seriously broken at the initial stage of storage, which reduces the processing quality of part of the grain and increases the difficulty of storage during static storage; and the third is that the dust is serious, a large amount of dust is generated during the falling process of the grain, causing blurred vision in the silo, and there is a hidden danger of dust explosion.

[0003] At present, there are many devices that can reduce the breakage rate of grain during storage and reduce automatic classification, mainly including a distributor and a chute.

[0004] The distributor uniformly distributes the grain to different areas in the silo by rotating, moving or throwing, and the core principle is to disperse the falling points of the grain to avoid the grain from being concentrated and accumulated in a certain area, but it cannot effectively prevent the grain from being broken, and even it may increase the breakage of the grain during storage, and the device is large in size and complex in structure, and it is difficult to install on the top of the silo, and the dust is more serious when the grain is stored.

[0005] The chute is a commonly used device for grain storage in a shallow circular silo or a vertical silo, and the grain can be smoothly and uniformly transported from the top of the silo to the inside of the silo through the chute, which can reduce the breakage of the grain, avoid automatic classification phenomenon and improve the storage efficiency. However, the chute is usually fixedly installed in the silo and extends from the top of the silo to the bottom of the silo, and its flexibility is limited, and after the grain storage is completed, the chute is buried by the grain, and the grain in contact with the chute is prone to breed mold and heat, and affects the deployment of the grain temperature detection pipeline; it seriously occupies the storage space of the silo, affecting the layout in the silo; it hinders the subsequent deployment of temperature and humidity detection pipelines in the grain pile, and it will also become a blind spot for grain pile ventilation and cooling during storage; after long-term use, the chute may be worn or blocked, and it can only be installed or repaired under the condition that there is no grain in the silo, so the maintenance difficulty is large.

[0006] In order to solve the problems of uneven texture of the grain pile in the silo after the grain is stored, serious breakage of the grain at the initial stage and serious dust, the structure of the grain storage needs to be improved, so as to solve the current technical problems.

The grain outlet end of pipeline 2 is provided with ultrasonic ranging sensor 10, ultrasonic ranging sensor 10 is electrically connected to control module, for measuring the distance between the grain outlet end of pipeline 2 and the ground or grain surface in real time.

[0023] The working principle of the utility model is summarized as follows:

[0024] Grain falls into the warehouse through grain inlet 5, flexible pipeline 2 in turn from the top of shallow round warehouse or vertical silo. Ultrasonic ranging sensor 10 is installed on the grain outlet end of flexible pipeline 2, for measuring the distance between the grain outlet end of pipeline 2 and the ground or grain surface in real time. The grain outlet end of flexible pipeline 2 is connected with the winch 6 of the output end of stepper motor 3 through cable 4. When the distance detected by ultrasonic ranging sensor 10 is less than 2 meters, stepper motor 3 starts and retracts cable 4, so that the grain outlet end of pipeline 2 is lifted as a whole, to avoid that the grain surface lifts and buries pipeline 2; when the distance is greater than 2 meters, stepper motor 3 stops rotating, to ensure that the grain outlet end of pipeline 2 maintains a constant distance from the ground or grain surface. The control module of the device is connected with the mobile phone Bluetooth, to realize the control of the device, so that the operation is more convenient, that is, workers do not need to specially operate the equipment at the specific position where the switch is located; it is not necessary to send a dedicated person to pay attention to the position of flexible pipeline outlet at any time, the distance between the grain outlet end of pipeline and the ground or grain surface can be measured in real time, to automatically start or stop the rotation of stepper motor, and then to maintain a certain distance between the grain outlet end of flexible pipeline and the ground or grain surface.

[0025] Compared with the cloth distributor, the device can reduce the automatic classification degree of the falling grain, reduce the grain breakage at the bottom of the warehouse, reduce the risk of dust explosion, and improve the working environment. Compared with the chute system, the device itself has a simple structure, is easy to install, has a low installation cost, and is easy to popularize. After the grain is stored in the warehouse, it will not be buried by the grain, and the installation and maintenance are convenient, and the grain in contact with the grain in the grain pile is prone to breed mold, heat, and affect the deployment of the grain temperature detection pipeline, forming a blind spot for ventilation and cooling operation.

[0026] Control module operating principle:

[0027] The device is connected with the ESP32 Bluetooth through the mobile phone APP "BLE debugging assistant" to realize remote control.

[0028] Input "1" to start the ultrasonic ranging sensor 10, input "2" to pause the ultrasonic ranging sensor 10. When the ultrasonic ranging sensor 10 continuously measures the distance less than 2 meters for 5 seconds, the step motor 3 is automatically started; when the distance measured continuously for 5 seconds is greater than 2 meters, the step motor 3 is automatically stopped. Input "3" can directly start the step motor 3 to retract the cable 4, and input "4" can start the step motor 3 to rotate in reverse to release the cable 4.

[0029] The principle of reducing the automatic classification degree of the falling grain:

[0030] Due to the restraint of the flexible pipe 2, the speed difference between the grain and the impurities is reduced when the grain falls, thereby reducing the separation and redistribution of the grain during movement. At the same time, compared with the case without a flexible pipe, the falling positions of the grain and the impurities are limited to the fixed area at the lower end of the flexible pipe 2, and the situation that the grain with large bulk density is concentrated in the center or bottom of the grain pile, and the impurities with light bulk density and large air resistance are scattered and gathered at the edge or surface of the grain pile will not be caused.

[0031] The principle of reducing the grain breakage at the bottom of the warehouse: the falling positions of the grain are limited to the fixed area at the lower end of the flexible pipe 2, except that part of the grain will directly fall to the ground at the initial stage of grain entering, which will form a small amount of breakage, and the subsequent grain will fall on the grain pile formed by the first falling grain, and basically will not be broken.

[0032] The principle of reducing dust: due to the restraint of the flexible pipe 2, the dust is concentrated in the pipe 2, and will not be scattered in a large area in the warehouse.

[0033] Finally, it should be pointed out that: the above only describes the preferred embodiments of the device, and is not used to limit the protection scope of the device. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the device shall be included in the protection scope of the device.
