Description

Technical Field

[0002] In the field of grain storage, to ensure the quality and safety of grains, precise control of the storage environment is crucial, and heat management of the storage core is a key link. During the storage process of grains, heat is generated due to factors such as respiration and microbial activities. If the heat cannot be effectively dissipated, it will lead to a local temperature increase, causing problems such as grain mildew and germination, resulting in huge economic losses.

[0003] Existing grain storage heat control methods mostly adopt traditional ventilation and heat dissipation measures, such as setting fixed ventilation openings in storage facilities or forcing ventilation by installing simple fans. These methods have many defects: First, the ventilation direction and range are fixed, making it difficult to flexibly adjust according to the actual heat distribution of the grain core in the storage, resulting in poor heat control effects; Second, it is impossible to accurately monitor the temperature at different depths of the grains in real time, making it difficult to quickly detect local heat anomalies; Third, during the operation of the ventilation equipment, sundries in the grains easily enter the ventilation ducts, causing duct blockages, affecting the ventilation and heat dissipation effects, and being inconvenient for cleaning and maintenance.

[0044] Refer to Figure 1-11 , an automatic core heat control device for grain storage, including a storage cylinder 1, a strip plate 2, a steering adjustment component, two mounting seats 21, two return pipes 22, a spacing adjustment component, a lifting adjustment component, a fan 3, two telescopic hoses 31, a guiding and limiting component, a plurality of feed pipes 11 and a plurality of discharge pipes 12;

[0045] The top of the storage cylinder 1 is open, and a placement groove penetrating through the top of the storage cylinder 1 is provided at a position close to the inner wall of the storage cylinder 1. The strip plate 2 is clamped in the placement groove and is in sliding contact with the inner wall of the placement groove.

[0046] Both of the two mounting seats 21 are slidably sleeved on the strip plate 2. A plurality of air outlet holes 2201 are provided on the return pipe 22, and a plurality of temperature sensors 2202 are fixedly installed on the return pipe 22. The plurality of temperature sensors 2202 and the plurality of air outlet holes 2201 are arranged in an alternating manner.

[0047] A tooth disc 201 is fixedly installed on the bottom side of the strip plate 2, and a motor 1 202 is fixedly installed on the outside of the storage cylinder 1. A driving gear 203 meshing with the tooth disc 201 is fixedly sleeved on the output shaft of the motor 1 202, which can control the strip plate 2 to perform a turning operation centered on the axis of the storage cylinder 1 as needed.

[0048] A strip-shaped groove is formed in the bottom side of the strip-shaped plate 2. The same bidirectional lead screw 211 is rotatably installed on the inner walls of both sides of the strip-shaped groove. Two sliders 215 respectively fixedly connected to the corresponding mounting seats 21 are slidably installed in the strip-shaped groove. Both of the two sliders 215 are threadedly connected to the bidirectional lead screw 211, and can adjust the distance between the two mounting seats 21 when the bidirectional lead screw 211 rotates, so as to be able to adjust the distance between the two return pipes 22. A worm gear 212 is fixedly sleeved on the bidirectional lead screw 211. A second motor 213 is fixedly installed on the top side of the strip-shaped plate 2. The output shaft of the second motor 213 extends into the strip-shaped groove and is fixedly connected with a worm 214. The worm 214 meshes with the worm gear 212 and can provide driving force for the bidirectional lead screw 211;

[0049] The two return pipes 22 are respectively vertically slidably installed on the corresponding mounting seats 21. Support blocks are fixedly installed at both ends of the top side of the strip-shaped plate 2. The same rotating shaft 221 is rotatably installed on the two support blocks. A third motor 222 is fixedly installed on one of the support blocks. The output shaft of the third motor 222 is axially fixedly connected with the rotating shaft 221. Two sliding sleeves 223 are axially slidably installed on the outer side of the rotating shaft 221. Transmission gears 224 are fixedly sleeved on both of the two sliding sleeves 223. Tooth plates 225 are embedded and fixedly installed on the two return pipes 22. The two transmission gears 224 respectively mesh with the corresponding tooth plates 225, and can synchronously control the two return pipes 22 to lift, so as to be able to adjust the heights of the air outlets 2201 and the temperature sensors 2202, and further be able to blow air to different positions in the grain in the storage cylinder 1 and monitor the temperatures of the grain at different depths in real time. In order to avoid dust and other sundries from affecting the normal transmission between the transmission gear 224 and the tooth plate 225, and at the same time enable the sliding sleeves 223 to keep in a synchronous movement state corresponding to the mounting seats 21, so as to ensure that the transmission gear 224 and the tooth plate 225 are always in a meshing state, protective shells 226 are fixedly installed on both of the two mounting seats 21. The two sliding sleeves 223 are respectively rotatably installed on the corresponding protective shells 226, and the position where the transmission gear 224 meshes with the tooth plate 225 is located inside the protective shell 226. At the same time, in order to ensure that the sliding sleeves 223 slide stably along the axis of the rotating shaft 221 and avoid relative rotation between the sliding sleeves 223 and the rotating shaft 221, the cross section of the rotating shaft 221 is polygonally arranged;

[0050] The blower 3 is fixedly installed on the strip-shaped plate 2, and the two return pipes 22 are respectively communicated with the air outlet of the blower 3 through telescopic hoses 31. In order to provide stable support for the blower 3 while avoiding affecting the installation position of the second motor 213, a mounting frame is fixedly installed at the center of the top side of the strip-shaped plate 2, and the blower 3 is fixedly installed on the top of the mounting frame;

[0051] An annular groove and an arc-shaped opening are respectively formed in the side wall of the placement groove and at both ends of the strip plate 2. A plurality of adjusting screw rods 41 are threadedly installed on the storage cylinder 1 in a radial pattern centered on the axis of the storage cylinder 1. The plurality of adjusting screw rods 41 all penetrate through the annular groove and are rotatably installed with limiting wheels 42. One end of each of the plurality of adjusting screw rods 41 away from the limiting wheel 42 is fixedly installed with an adjusting wheel 4. At least two of the plurality of limiting wheels 42 respectively and simultaneously roll and abut against the inner bottom wall of the corresponding arc-shaped opening, which can provide a guiding and limiting effect on the strip plate 2 placed in the placement groove, and at the same time facilitate the quick disassembly and assembly operation of the strip plate 2;

[0052] A plurality of feed pipes 11 and a plurality of discharge pipes 12 are respectively fixedly installed on the outer top and outer bottom of the storage cylinder 1.

[0053] In this embodiment, in order to prevent sundries in the grain from entering the return pipe 22 through the air outlet 2201 and causing blockage, an air filter sponge is filled in the middle and lower part of the return pipe 22.

[0054] Among them, the air inlet of the fan 3 is arranged on its side, and a net cover for preventing sundries from being sucked into the fan 3 is fixedly installed on the side of the fan 3.

[0055] Furthermore, in order to improve the automation degree and intelligent level of the entire device, a control system can be further set up. The control system can include a processor, a memory, and a communication module connected to each motor (motor one 202, motor two 213, and motor three 222), temperature sensor 2202, and fan 3. The processor can receive real-time temperature data from the temperature sensor 2202 according to preset algorithms and programs, and perform analysis and processing. When detecting abnormal temperature, the processor can send a start signal to the fan 3 through the communication module to make it start working, and blow air to the grain in the storage cylinder 1 through the telescopic hose 31 and the return pipe 22 to achieve the purpose of temperature adjustment. At the same time, the processor can also adjust the position of the return pipe 22 in the storage cylinder 1 by controlling the working states of the motor one 202, motor two 213, and motor three 222, in cooperation with the strip plate 2 and the mounting seat 21, so as to be able to flexibly adjust the range and position of air blowing and temperature detection. In addition, the memory can be used to store preset algorithms, programs, temperature thresholds and other data, as well as record the operating status and historical data of the device, which is convenient for subsequent analysis and maintenance. Through such a setting, the entire device can achieve automatic control and intelligent monitoring, greatly improving the efficiency and safety of grain storage.

[0056] Working principle: When in use, first connect the power supply to start the first motor 202. The output shaft of the first motor 202 drives the drive gear 203 to rotate. Since the drive gear 203 meshes with the toothed disk 201, the strip-shaped plate 2 is driven to perform a turning operation centered on the axis of the storage cylinder 1, thereby adjusting the blowing direction and temperature detection direction of the air outlet holes 2201 and the temperature sensors 2202 on the return-shaped pipe 22.

[0057] When it is necessary to adjust the distance between the two return-shaped pipes 22, start the second motor 213. The output shaft of the second motor 213 drives the worm 214 to rotate. Since the worm 214 meshes with the worm wheel 212, the bidirectional lead screw 211 is driven to rotate. The two sliders 215 are respectively threadedly connected to the bidirectional lead screw 211. Therefore, when the bidirectional lead screw 211 rotates, it will drive the two sliders 215 to approach or move away from each other, thereby adjusting the distance between the two mounting seats 21 and realizing the adjustment of the distance between the two return-shaped pipes 22 to meet the requirements of different blowing ranges and temperature detection ranges.

[0058] When it is necessary to adjust the height of the air outlet holes 2201 and the temperature sensors 2202, start the third motor 222. The output shaft of the third motor 222 drives the rotating shaft 221 to rotate. Two sliding sleeves 223 are axially slidably mounted on the outer side of the rotating shaft 221. Transmission gears 224 are fixedly sleeved on the two sliding sleeves 223. The two transmission gears 224 respectively mesh with the corresponding toothed plates 225. Therefore, when the rotating shaft 221 rotates, it will drive the two sliding sleeves 223 to rotate synchronously, so that the two return-shaped pipes 22 can be driven to rise and fall synchronously under the cooperation of the transmission gears 224 and the toothed plates 225, realizing the adjustment of the height of the air outlet holes 2201 and the temperature sensors 2202.

[0059] At the same time, by rotating the adjusting wheel 4 to adjust the adjusting screw 41, the adjusting screw 41 drives the limiting wheel 42 to move, so that the limiting wheel 42 rolls and abuts against the bottom inner wall of the corresponding arc-shaped opening, thereby guiding and limiting the strip-shaped plate 2 and ensuring the stability of the strip-shaped plate 2 during the turning and lifting processes. In addition, the air blower 3 blows air into the two return-shaped pipes 22 through the telescopic hose 31. The air enters the storage cylinder 1 through the air outlet holes 2201 after being filtered by the air filter sponge, which can avoid sundries in the grain entering the interior of the return-shaped pipe 22 through the air outlet holes 2201 and causing blockage without affecting the blowing. The overall device is reasonably designed, easy to operate, and has high practicability.

[0060] The above has introduced in detail an automated core heat control device for grain storage provided by the present invention. Specific embodiments are applied in this article to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and modifications can still be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
