Description

Technical Field

[0001] The invention relates to the technical field of grain drying equipment, and in particular to an adaptive precision-controlled grain drying production device. Background Art

[0002] Grain drying is a crucial link in agricultural production. It not only affects the storage and transportation of grain, but is also directly related to the quality and safety of grain. Newly harvested grains contain high moisture content, which not only causes the grains to mold and germinate during storage, but may also attract pests and cause serious grain losses. Therefore, timely drying of grains to reduce their moisture content to a safe level is a key measure to ensure grain quality and extend storage period.

[0003] Traditional grain drying methods, such as drying in the sun, are simple and easy, but are greatly restricted by weather conditions, are inefficient, and are not suitable for large-scale operations. With the advancement of agricultural modernization, mechanized drying has become an inevitable choice. Grain dryers can quickly and evenly reduce grain moisture through hot air drying and other methods, improve drying efficiency, and meet the needs of large-scale production.

[0004] However, existing grain drying equipment still faces some challenges in practical applications. First, the energy consumption problem is prominent. Traditional drying equipment requires continuous heating, which not only consumes a lot of energy but also increases production costs. Secondly, the problem of drying uniformity. Due to the limited heat transfer effect in the equipment, it is easy to cause uneven drying of grains, affecting the quality of grains. In addition, existing equipment often cannot effectively screen out impurities and detached husks in grains after processing, reducing the practicality of drying grains.

[0005] In view of the above problems, it is urgent to carry out innovative design based on the original grain drying production equipment. Summary of the invention

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the adaptive precision-controlled grain drying production device, through the arrangement and coordination of the drying cylinder, the feeding structure and the exhaust structure, during the grain drying process, the device will adaptively add a certain proportion of iron balls according to the amount of grain added. These iron balls are mixed with the grains in the drying cylinder, which not only helps to evenly heat the grains, but also promotes the transfer of heat, ensuring that every grain can be fully dried. At the same time, the heat provided by the heating rod is evenly distributed, further improving the drying efficiency. Through the coordination of the exhaust structure, the drying cylinder can be maintained in a state close to vacuum, effectively reducing the boiling point of water. This innovative design significantly reduces energy consumption and reduces drying costs, while also shortening drying time and improving production efficiency.

[0016] The drive structure can simultaneously drive multiple drying cylinders and cooling cylinders to rotate, ensuring that the grains are evenly heated during the drying and cooling process. At the same time, it can drive the screening structure to work. After the grains are dried, the solenoid valve between the drying cylinder and the cooling cylinder is opened, and the dried grains in the drying cylinder fall into the cooling cylinder. The valve is closed, and the drying cylinder is loaded again for drying, while the hotter dried grains in the cooling cylinder are cooled down, which is convenient for subsequent screening and packaging.

[0017] The screening structure is set up so that the grains dried and cooled in the cooling cylinder, when the valve is opened and fall into the screening area, are driven by the drive structure. With the cooperation of bevel gear sets and full gear sets with different gear ratios, the fan assembly can rotate quickly to blow the grains toward the slag discharge mesh plate. In this process, impurities and grain skins will fall into the slag discharge trough through the fine mesh holes, while pure grains will continue to fall, pass through the guide rail column, and then pass through the bottom of the shell for packaging. In this process, when the iron balls in the grains touch the guide rail column, they will roll into the volleyball trough along its inclination angle, realizing the effective classification and collection of grains, impurities and iron balls, which is convenient for subsequent different treatments.

[0032] The diameter of the bevel gear of the bevel gear set 1207 on the vertical shaft 1208 is larger than the diameter of the bevel gear connected to the fan assembly 1206 , and the diameter of the full gear of the full gear set 1209 on the vertical shaft 1208 is smaller than the diameter of the full gear located on the driving structure 13 .

[0033] The driving structure 13 includes a second driving motor 1301, a transmission chain 1302, a driving shaft 1303, and a driving full gear 1304. The second driving motor 1301 is installed on the outer wall of the shell 1, and the output end of the second driving motor 1301 is connected to the transmission chain 1302, and the transmission chain 1302 runs through the shell 1 and is connected to a plurality of driving shafts 1303 through a sprocket.

Another driving full gear 1304 is connected, and the other driving full gear 1304 is meshed with the corresponding outer wall tooth block of the cooling cylinder 4.

[0034] Working principle: First, when loading, the rotating shaft 804 is controlled to rotate an appropriate number of times, and at the same time, the sprocket and chain 807 drive another rotating shaft 804 to rotate at the same time. The rotation of the rotating shaft 804 drives the first rotating block 805 and the second rotating block 806 to rotate at the same time, so that each time the first rotating block 805 rotates one circle, the two notches on it carry two portions of the same amount of grains into the drying cylinder 3. At the same time, when the second rotating block 806 rotates one circle, the notch on it will drive an iron ball into the drying cylinder 3, so as to achieve the goal of adding an appropriate amount of iron balls according to the amount of grains, which is convenient for subsequent quantitative packaging. At the same time, the addition of iron balls is conducive to the uniform conduction of heat during subsequent heating.

[0035] Then the exhaust structure 9 is started, and the first motor 912 drives the rotating shaft 911 and the convex gear 910 to rotate. The convex gear 910 periodically engages and drives the connecting gear rod 908 and the open piston plate 906 to move upward, and the return spring 909 is compressed. When the engagement is disengaged, the return spring 909 pushes the open piston plate 906 to move downward and reset. When the open piston plate 906 moves upward, the baffle 907 is closed with its upper opening. Under atmospheric pressure, the blocking block 904 is disengaged from the engagement seal with the air inlet 902, so that the air in the drying cylinder 3 is sucked into the air cylinder 901. When the open piston plate 906 moves downward, the air sucked into the air cylinder 901 lifts the baffle 907 and passes through the opening and the air outlet 903 to be discharged. This process is repeated many times, so that the drying cylinder 3 is close to a vacuum state, which reduces the boiling point of the water in the grains, which is beneficial to the subsequent evaporation of the water in the grains. Due to the vacuum environment, when the grains are heated, the water inside them will begin to evaporate due to the increase in temperature. Since there is no atmospheric pressure in the vacuum environment, the water will directly change from liquid to gas, and pass through the pressure gauge on the drying cylinder 3. After the water vaporizes, it fills the drying cylinder 3. The exhaust structure 9 is started again to extract the water vapor in the drying cylinder 3 to the outside. The PLC control board controls the solenoid valve between the drying cylinder 3 and the cooling cylinder 4 to open, and the dried grains in the drying cylinder 3 fall into the cooling cylinder 4. The valve is closed, and the drying cylinder 3 is loaded with materials for drying again, while the grains falling into the cooling cylinder 4 are cooled for subsequent packaging.

[0036] After cooling, the solenoid valve at the lower end of the cooling cylinder 4 opens, and the grains fall into the discharge channel 1201. The driving shaft 1303 drives the full gear set 1209, the vertical shaft 1208, the bevel gear set 1207 and the fan assembly 1206 to rotate. Through the influence of the gear ratio, the fan assembly 1206 rotates rapidly, and the grains passing through the discharge channel 1201 are blown to the slag discharge mesh plate 1205. Impurities and grain skin fragments pass through the mesh holes and enter the slag discharge trough 1204 for collection. The grains and iron balls continue to fall, and the grains are collected by being packaged through the bottom of the shell 1, while the iron balls contact the guide column 1202, and roll along the guide column 1202 to the ball discharge trough 1203 for collection. This is the working principle of the adaptive precision control grain drying production device.
