Description

Technical Field

[0001] The invention relates to the technical field of moisture-proof grain storage, in particular to a moisture-proof grain storage device. Background Art

[0002] Moisture-proof storage of grain is extremely important because moisture is one of the key factors affecting grain quality and storage stability. When the moisture content of grain exceeds the safe storage limit, it is easy to breed harmful organisms such as mold and pests, causing grain mildew, heat, caking, loss of nutrients, and the production of toxic and harmful substances, resulting in a decline in the quantity and quality of grain, affecting the edible value and economic value of grain. Ventilation is often used for treatment, relying on the natural pressure and temperature differences to make air flow in the storage space and take away the humid air. For example, when the temperature difference between morning and evening is large, the vents of the granary are opened to let cold air in and hot and humid air out. By installing ventilators, ventilation ducts and other equipment, the air flow is forced and the humidity is adjusted. The ventilation time, intensity and airflow direction can be controlled more accurately.

[0003] Grain silos are often used for moisture-proof storage of grain. When grain needs to be taken out of the silo during the moisture-proof storage process, the grain is directly discharged or taken out of the silo. It is inconvenient to measure the grain during the process of taking out the grain, which makes it inconvenient for users to accurately grasp the amount of grain taken out, affects the amount of grain used, and causes a large deviation in the total amount of grain.

[0004] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing grain moisture-proof storage devices on the market, and even if they can be solved, they need to be solved with the cooperation of external tools, which cannot achieve the desired effect.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Embodiment 1

[0035] See also Figure 1-Figure 9 The present invention provides a technical solution: a moisture-proof storage device for grains, comprising a main body 1, the main body 1 comprising a main bin body 11, a bin cover 12 is arranged above the main bin body 11, two ventilation tubes 13 are fixedly connected inside the bin cover 12, a ventilation pipe 14 is fixedly connected inside the main bin body 11, a fan 15 is fixedly connected at the bottom of the ventilation pipe 14, a discharge pipe 18 is fixedly connected at the bottom of the main bin body 11, an electric discharge valve 19 is fixedly connected inside the discharge pipe 18, a mounting rod 17 is fixedly installed on the inner wall of the main bin body 11, a temperature and humidity measuring device 16 is fixedly installed on the outer surface of the mounting rod 17, and a material taking mechanism 2 is arranged below the main bin body 11;

[0036] The material taking mechanism 2 includes a container displacement unit 21, which is located below the main bin body 11. The container displacement unit 21 is used to raise and lower the grain collecting device, and can switch between the grain collecting function and the weighing function.

[0037] As a further limitation of the material taking mechanism 2 of the present invention, the container displacement unit 21 includes an integral bracket 2101, and the inner side wall of the integral bracket 2101 is provided with a plurality of identical limiting guide grooves 2103, and a ball screw 2104 is arranged inside each limiting guide groove 2103, and the outer surface of each ball screw 2104 is threadedly connected with a matching nut 2102, and the outer surface of each matching nut 2102 is fixedly installed with a lifting block 2113, and the outer surface of each lifting block 2113 is connected to the limiting guide groove 21 03, a support plate 2109 is fixedly installed on the side of each lifting block 2113 away from the integral bracket 2101, a shock absorber 2108 is fixedly installed on the upper surface of each support plate 2109, an arc plate 2106 is fixedly installed on the upper surface of each shock absorber 2108, and two sets of anti-vibration guide rods 2107 are fixedly installed on the upper surface of each arc plate 2106. A driving motor 2110 is fixedly installed on the inner bottom wall of the integral bracket 2101, and the internal rotation connection of the integral bracket 2101 An annular frame 2114 is connected, and a plurality of rolling balls 2115 are rotatably connected inside the annular frame 2114, and the plurality of rolling balls 2115 are rotatably connected inside the integral bracket 2101. The annular frame 2114 is provided with tooth grooves 2116 arranged at equal distances inside. A large gear 2111 is fixedly connected to the output end of the driving motor 2110, and the outer surface of the large gear 2111 is meshed with the tooth groove 2116. A small gear 2112 is fixedly connected to the lower part of the outer surface of each ball screw 2104, and the outer surface of each small gear 2112 is meshed with the tooth groove 2116. By providing a container displacement unit 21, the grain collecting part can be displaced up and down. Since the grain will have a certain vibration when being collected, the influence of the vibration of the grain collecting part can be reduced, and the grain collecting part can be placed on the weighing part as a whole, which does not affect the normal weighing of the grain collecting part by the weighing part. The elevation of the grain collecting part can facilitate the collection of grain and facilitate the discharge of grain at a certain height.

[0038] See also Figure 1 and Figure 2 Two bearings 2105 are fixedly installed on the outer surface of each ball screw 2104, and the outer surface of each bearing 2105 is fixedly connected to the inner wall of the integral bracket 2101. The bearings 2105 support the rotation of the ball screw 2104, thereby ensuring the position accuracy of the ball screw 2104 in the axial direction.

[0039] The specific implementation of this embodiment is as follows: the main warehouse 11 stores grain inside. After a certain amount of grain is stored inside the main warehouse 11, it is closed with a warehouse cover 12. The main warehouse 11 is equipped with a temperature and humidity detector 16. The temperature and humidity detector 16 mainly includes two parts: temperature measurement and humidity measurement. The temperature and humidity detector 16 has multiple types such as digital and pointer types, which can be selected according to needs. When the temperature is too high or the humidity is too high, the fan 15 is started. The fan 15 introduces relatively dry air from the outside into the main warehouse 11 through the ventilation pipe 14, and at the same time, the humid air in the main warehouse 11 is When the dry and cold air from the outside enters the main bin body 11, the absolute humidity of the air in the main bin body 11 remains unchanged, but the relative humidity will decrease due to the change in temperature, and the airflow generated by the fan 15 can accelerate the evaporation of moisture on the surface of the grain, and the grain in the main bin body 11 can be treated to prevent moisture, and natural ventilation can be carried out through the ventilator 13 to promote air circulation. When it is necessary to take the grain in the main bin body 11, the drive motor 2110 is started, and the drive motor 2110 can drive the annular frame 2114 through the meshing relationship between the large gear 2111 and the tooth groove 2116. The integral support 2101 rotates inside, and then the ball screw 2104 can be driven to rotate through the meshing of the tooth groove 2116 and the pinion 2112. Moreover, when the annular frame 2114 rotates, the rolling ball 2115 can increase the rotation stability and smoothness of the annular frame 2114. The ball screw 2104 cooperates with the matching nut 2102 for transmission, and the rotational motion of the ball screw 2104 is converted into the linear motion of the matching nut 2102, which can drive the lifting block 2113 to rise. During the lifting process of the lifting block 2113 in the limiting guide groove 2103, the anti- The vibration guide rod 2107 will be inserted into the corresponding structure, which can drive the grain collecting part to rise. Since the grain collecting part has a vibration effect, the shock absorber 2108 can reduce the impact of the vibration on the lifting block 2113, the ball screw 2104 and the matching nut 2102. When the lowering operation is required, it is only necessary to control the driving motor 2110 to reverse, and the ball screw 2104 and the matching nut 2102 will cooperate to lower the arc plate 2106 and the support plate 2109, so that the grain collecting device can be lowered to a certain extent, which is convenient for the next weighing operation.

[0040] Embodiment 2

[0041] See also Figure 1 , Figure 3 and Figure 5-Figure 7 The present invention provides a technical solution: a moisture-proof storage device for grain. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. The material taking mechanism 2 also includes a collecting and discharging unit 22. The collecting and discharging unit 22 is located inside the container displacement unit 21. The collecting and discharging unit 22 is used to vibrate and collect the grain, and discharge the grain after it is weighed.

[0042] As a further limitation of the material taking mechanism 2 of the present invention, the collecting and discharging unit 22 includes a collecting container 2201, a plurality of identical vibration motors 2206 are fixedly installed on the bottom surface of the collecting container 2201, a plurality of identical guide sleeves 2207 are fixedly installed on the bottom surface of the collecting container 2201, each guide sleeve 2207 is located directly above the shockproof guide rod 2107, an inclined material plate 2208 is fixedly installed on the inner wall of the collecting container 2201, a tube hole 2209 is opened at the bottom end of the upper surface of the inclined material plate 2208, a feed pipe 2205 is fixedly installed on the inner wall of the tube hole 2209 and the inner wall of the collecting container 2201, and the feed pipe 2205 A conical portion 2214 is provided on the upper side of the inner wall, a spiral rod 2210 is provided inside the feeding pipe 2205, a connecting rod 2212 is provided at the top of the spiral rod 2210, a servo motor 2213 is fixedly installed at the top of the connecting rod 2212, and the bottom surface of the servo motor 2213 is fixedly connected to the upper surface of the collecting container 2201. By providing a collecting and discharging unit 22, the grain can be collected centrally at the bottom of the main bin 11, and the collection and discharging unit 22 has a vibration function to ensure the uniform distribution of the grain in the collecting container 2201. After the grain is measured, the grain can be discharged centrally, so as to achieve the purpose of quantitatively discharging the grain and thus using it in a quantitative manner.

[0043] See also Figure 5 A positioning hole 2204 is provided on the bottom surface of the collecting container 2201, and the positioning hole 2204 is located at the center of the bottom of the collecting container 2201. The positioning hole 2204 is provided to locate the bottom of the collecting container 2201, so as to facilitate the determination of the accurate position of the collecting container 2201 in the weighing part;

[0044] See also Figure 6 , four mounting plates 2202 are fixedly mounted on the inner wall of the collection container 2201, and the inner wall of each mounting plate 2202 is threadedly connected with a contact sensor 2203. By providing the mounting plates 2202 and the contact sensors 2203, the contact sensors 2203 are screwed into the mounting plates 2202, and the height of the grain collected in the collection container 2201 can be limited according to the height adjustment of the contact sensors 2203, and can be adjusted according to the needs. Under the height limit condition, different taking amounts can be selected;

[0045] See also Figure 6 Two couplings 2211 are fixedly installed on the outer surface of the connecting rod 2212, and the inner walls of the two couplings 2211 are fixedly connected to the output end of the servo motor 2213 and the top of the screw rod 2210 respectively. By providing the coupling 2211, the connecting rod 2212 is respectively connected to the servo motor 2213 and the screw rod 2210, so that the servo motor 2213 can drive the screw rod 2210 to rotate synchronously and ensure the stable transmission of torque.

[0046] The specific implementation of this embodiment is as follows: during the rising process of the anti-vibration guide rod 2107, it will be directly inserted into the guide sleeve 2207. As the anti-vibration guide rod 2107 continues to rise, it will drive the collection container 2201 to rise to a certain degree. When it is at a certain height from the discharge pipe 18, the drive motor 2110 is turned off. After the drive motor 2110 stops, the lifting block 2113, the support plate 2109 and the anti-vibration guide rod 2107 will support the collection container 2201 to maintain the specified position. After the position of the collection container 2201 is determined, , open the electric discharge valve 19, the grain is discharged from the discharge pipe 18 and falls into the collection container 2201. Since different types of grains are stored in different main bins 11, in order to avoid the grains from piling up in a certain place in the collection container 2201, the vibration motor 2206 can be started during the grain collection process. The vibration motor 2206 vibrates the collection container 2201, which can handle the accumulation of grains and ensure the uniform distribution of grains in the collection container 2201, which is convenient for the next weighing operation. When the grain is discharged from the device 2201, the servo motor 2213 can be started, and the servo motor 2213 drives the connecting rod 2212 to rotate through the coupling 2211, and then the connecting rod 2212 drives the spiral rod 2210 to rotate, so that the grain is discharged from the conveying pipe 2205. The inclination of the inclined material plate 2208 itself ensures that the grain will be concentrated at one point and gathered at the conveying pipe 2205. The conveying pipe 2205 also has a tapered portion 2214, which can prevent the grain from piling up or clogging at the edge of the conveying pipe 2205. The servo motor 2213 is controlled at a relatively high level, and in conjunction with the screw rod 2210, it can more accurately control the discharge of grain and control its amount. The overall capacity in the collection container 2201 can be controlled and detected using the contact sensor 2203. The height of the contact sensor 2203 is the highest position for grain collection. Different amounts can be selected at the height of the contact sensor 2203 and adjusted according to demand. After the grain in the collection container 2201 is collected to the specified height, the electric discharge valve 19 is closed.

[0047] Embodiment 3

[0048] See also Figure 1-Figure 3 , Figure 5 and Figure 8 The present invention provides a technical solution: a moisture-proof storage device for grain.

By providing the weighing mechanism 3, the grain in the collection container 2201 can be weighed as a whole, and the weight reduction of the collection container 2201 can be observed while the collection container 2201 discharges the grain, so as to achieve the function of accurately controlling the amount of grain taken and prevent the problem of large deviation in the amount of grain used;

[0050] See also Figure 5 and Figure 8 A positioning column 304 is fixedly installed on the upper surface of the weighing platform 303. The positioning column 304 is located in the center of the weighing platform 303. The positioning column 304 can cooperate with the positioning hole 2204 to ensure the accurate placement of the collection container 2201 and limit the movement of the collection container 2201 to prevent the collection container 2201 from displacement.

[0051] See also Figure 1 and Figure 8 Four fixed angle plates 308 are fixedly installed on the outer surface of the base 302, and the bottom surface of each fixed angle plate 308 is fixedly connected to the inner bottom wall of the integral bracket 2101. The fixed angle plates 308 are installed in the integral bracket 2101 to install and fix the base 302, thereby ensuring the stability of the position of the base 302.

[0052] The specific implementation of this embodiment is as follows: after collecting grain at the position of the discharge pipe 18, the drive motor 2110 can be started to make the large gear 2111 on it rotate in the opposite direction, and the ball screw 2104 is driven to reverse through the tooth groove 2116 on the annular frame 2114 in cooperation with the small gear 2112, and the matching nut 2102 moves downward, and the lifting block 2113, the support plate 2109, the arc plate 2106 and the shockproof guide rod 2107 also move downward, bringing the collection container 2201 down. As the collection container 2201 descends, the collection container 2201 will contact the weighing platform 303, and the positioning column 304 is inserted in the positioning hole 2204 to prevent the collection container 2201 from being damaged. The collecting container 2201 moves. After the collecting container 2201 contacts the weighing platform 303, the shockproof guide rod 2107 will continue to descend until the shockproof guide rod 2107 is separated from the guide sleeve 2207 and no longer provides support for the collecting container 2201, so that the collecting container 2201 is completely placed on the weighing platform 303, and then the collecting container 2201 is weighed by the weighing sensor 306. The data detected by the weighing sensor 306 is transmitted to the control instrument 301. The operator can observe the data on the control instrument 301, and then control the discharge of the servo motor 2213 and the screw rod 2210 to control the discharge amount of grain in the collecting container 2201.
