Description

Technical Field

[0001] The invention relates to the technical field of grain drying, in particular to a dryer capable of automatically adjusting drying efficiency according to the humidity of the surrounding environment. Background Art

[0002] Grain drying equipment typically consists of a dryer, a conveying system, and a control system. The dryer uses heat and ventilation to evaporate moisture from the grain, reducing its humidity. This helps prevent mold, spoilage, and loss of nutritional value. Grain drying equipment plays a vital role in agricultural production, improving grain quality and storage stability. However, existing dryers have numerous drawbacks and cannot meet practical needs.

[0003] The drying efficiency of conventional grain drying equipment is fixed, but different batches of grain have different moisture contents when initially collected, so the amount of water that needs to be dried out is also different. Even for the same batch of grain, the moisture content will vary during transportation and storage due to different conditions, which will lead to insufficient or excessive dehydration of the grain, which is not conducive to long-term storage of grain.

[0004] When conventional grain drying equipment is drying grains, the grains will be stacked on each other and there will be local uneven distribution. In this case, it is usually necessary to stop the machine to flatten and turn the grains. This operation will greatly reduce the drying efficiency of the grains and also affect the degree of automation of the grain drying equipment. Summary of the Invention

[0005] The object of the present invention is to provide a dryer that automatically adjusts the drying efficiency according to the humidity of the surrounding environment, so as to solve the problems raised in the above background technology.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a dryer that automatically adjusts drying efficiency based on ambient humidity, comprising a main housing, a conveying unit, a flattening unit, a drying assembly, and a detection assembly. The main housing is securely connected to the ground, the flattening unit and the drying assembly are disposed within the main housing, the lower end of the conveying unit is embedded within the main housing, the detection assembly is disposed on the side of the conveying unit, the detection assembly is securely connected to the outer wall of the main housing, the flattening unit is connected to the bottom of the conveying unit, and the drying assembly is connected to the side of the flattening unit away from the conveying unit. The conveying unit feeds grain into the main housing, the detection assembly detects relative humidity, the flattening unit flattens the grain, and the flattened grain is conveyed to the drying assembly for drying.

[0007] Furthermore, the conveying unit includes a collection hopper, a guide tube, and a guide component. The collection hopper and the guide tube are tightly connected. The guide tube is embedded in the main housing and tightly connected to the main housing. The detection assembly is disposed outside the guide tube, and the guide component is connected to the collection hopper. Grain is fed from the collection hopper, the guide tube guides the grain to the flattening unit, and the guide component guides the collection hopper to prevent grain blockage.

[0008] Furthermore, the guide component includes a guide cone, a connecting post, a connecting pipe, a guide vane, and a mounting frame. The mounting frame is fastened to the bottom side wall of the collecting hopper, the connecting pipe is rotatably connected to the mounting frame, and the connecting post is slidably connected to the connecting pipe. Two connecting posts are provided, one on the upper and lower sides of the connecting pipe, and the connecting post located on the upper side of the connecting pipe is fastened to the guide cone. The surface of the guide cone is provided with spiral patterns, and the connecting post located on the lower side of the connecting pipe is fastened to the guide vane. Multiple guide vanes are provided, and the multiple guide vanes are evenly distributed around the connecting post. When the grain falls onto the guide cone, it slides along the spiral patterns on the guide cone. The lateral force during the sliding process drives the guide cone to rotate, and the rotation of the guide cone drives the connecting post to rotate, which drives the connecting post to rotate the connecting pipe, which drives the connecting post located on the lower side to rotate, and the connecting post located on the lower side drives the guide vane to rotate, thereby stirring and dredging the grain.

[0009] Furthermore, a first rack, a second rack, a positioning gear, and a return spring are provided inside the connecting tube. The first rack is tightly connected to the connecting post located on the upper side of the connecting tube, the second rack is tightly connected to the connecting post located on the lower side of the connecting tube, the positioning gear is rotatably connected to the connecting tube, the first rack and the second rack are respectively meshed with the two sides of the positioning gear, one end of the return spring is tightly connected to the connecting post located on the upper side of the connecting tube, and the other end of the return spring is tightly connected to the connecting post located on the lower side of the connecting tube. During the falling process of the grain, the guide cone will be continuously impacted by the grain. Since the amount of grain falling per unit time fluctuates, the falling impact on the guide cone will change. The first rack will move with the change in the falling impact. The first rack meshes with the positioning gear, driving the positioning gear to rotate. The positioning gear drives the second rack to rotate. As the guide cone moves downward, the guide vanes move upward accordingly. The return spring will push the guide cone and the guide vanes to reset when the falling impact decreases. This structure greatly improves the smoothness of grain input.

[0010] Furthermore, the flattening unit includes a receiving trough, a distribution plate, an adjustment groove, and an adjustment component. The receiving trough and the distribution plate are fastened together. The receiving trough is arranged below the guide tube. The distribution plate is fastened to the side wall of the main box. The distribution plate is tilted. The end of the distribution plate close to the receiving trough is higher than the end of the distribution plate away from the receiving trough. An installation cavity is provided inside the distribution plate. The adjustment groove is arranged on the upper surface of the distribution plate. There are multiple groups of adjustment grooves. The multiple groups of adjustment grooves are evenly distributed along the surface of the distribution plate. There are multiple groups of adjustment components. One end of the adjustment component is located in the installation cavity, and the other end of the adjustment component extends from the adjustment groove. The grain falls from the guide tube onto the receiving trough. The receiving trough guides the grain onto the distribution plate. The grain slides down along the distribution plate. During the sliding process, the adjustment component flattens the grain. The flattened grain is transported to the drying assembly.

[0011] Furthermore, the adjustment component includes a lifting sleeve, a pressure rod, an adjustment wheel, and a power wheel. The lifting sleeve and the adjustment groove are slidably connected, the adjustment wheel is arranged on the inner side of the lifting sleeve, the adjustment wheel and the lifting sleeve are rotatably connected, the power wheel and the distribution plate are rotatably connected, one end of the pressure rod is tightly connected to the lifting sleeve, and the other end of the pressure rod is tightly connected to the distribution plate. The power wheel of the present invention is provided with an independent drive, the power wheel is divided into two groups from the middle position, the upper sides of the two groups of power wheels rotate toward the middle position, driving the adjustment wheel to be divided into two groups from the center position of the distribution plate, the upper sides of the two groups of adjustment wheels rotate toward the two sides of the distribution plate, when the grain is transported to the distribution plate, it will produce pressure on the distribution plate, the upper side of the distribution plate located in the center has more grain, and the adjustment wheel here is subjected to greater pressure, the corresponding lifting sleeve will press the pressure rod downward, the pressure rod is filled with gas, and the pressure limit can be set by adjusting the amount of gas. When the weight of the grain exceeds the standard, the pressure rod is compressed, the adjustment wheel will press on the power wheel, and the rotation of the power wheel drives the adjustment wheel to rotate. The adjustment component of the present invention adjusts the grain dispersion by measuring the difference in the amount of grain accumulated in the middle and at the edges after the grain falls. When the grain accumulation weight exceeds the standard, the lifting sleeve is pressed down, driving the adjustment wheel to contact the power wheel, and the adjustment wheel moves the bottom grain, moving the bottom grain toward the periphery. When the grain accumulation weight reaches the standard, the adjustment wheel automatically stops rotating, greatly improving the overall automation level of the device. This setting greatly improves the flatness of the grain during drying and improves the uniformity of grain drying.

[0012] Furthermore, the drying assembly includes a drying box, a heating plate, a conveyor belt, a setting frame, an impact column, and a driving cylinder. The drying box is arranged inside the main box body, the conveyor belt is fastened to the drying box via a bracket, the heating plate is arranged above the conveyor belt, the heating plate is fastened to the upper side of the inner wall of the drying box, the setting frame is fastened to the lower side of the inner wall of the drying box, the setting frame passes through the middle of the conveyor belt, the driving cylinder is fastened to the setting frame, the output shaft of the driving cylinder is fastened to the impact column, and multiple groups of driving cylinders and impact columns are provided, and the driving cylinders and impact columns are inclined toward the flattening unit. The grains are conveyed to the conveyor belt by the flattening unit, and driven by the conveyor belt, the grains move toward the side away from the flattening unit. During the movement, the heating plate dries the grains. When the grains move to the corresponding position of the impact column, the driving cylinder drives the impact column to impact the upper surface of the conveyor belt. The grains of the present invention originally have an initial velocity away from the side of the flattening unit, and are subjected to the impact force of the impact column toward the side of the flattening unit. In the thrown state, there is a force deviation between the lower side grains and the upper side grains, and the grains are turned over. This structure realizes the non-stop turning of the grains, which greatly improves the drying effect of the grains.

[0013] Furthermore, the detection component includes a first setting box, a second setting box, a covering sleeve, an input net, and an output net. The first setting box, the second setting box and the main box are tightly connected, the covering sleeve is tightly connected to the guide tube, the input net and the output net are arranged on the side wall of the guide tube, the covering sleeve is internally provided with a first cavity and a second cavity, the first cavity is connected to the input net, the first setting box is connected to the first cavity through a pipe, the second cavity is connected to the output net, the second setting box is connected to the second cavity through a pipe, an air flow pump is arranged inside the first setting box, and a humidity detector is arranged inside the second setting box. The air flow pump and the humidity detector are both conventional technical means of those skilled in the art, and their specific structures are not described. When the grain passes through the guide tube, the air flow pump will pump external air into the first cavity, the air flow enters the guide tube through the input net, and enters the second cavity from the output net carrying moisture on the surface of the grain. The air flow inside the second cavity is transported to the humidity detector, which detects the humidity of the air flow and controls the drying time according to the humidity of the air flow. For grains with higher humidity, the drying time is increased.

[0014] Compared with the prior art, the present invention achieves the following beneficial effects: the guide component of the present invention slides along the spiral lines on the guide cone after the grain falls. The lateral force during the sliding process drives the guide cone to rotate. Since the amount of grain falling per unit time fluctuates, the falling impact on the guide cone will vary. The first rack will move with the change of the falling impact. The first rack meshes with the positioning gear, driving the positioning gear to rotate. The positioning gear drives the second rack to rotate. As the guide cone moves downward, the guide vanes move upward accordingly. The return spring pushes the guide cone and guide vanes back to their original position when the falling impact decreases. This structure greatly improves the smoothness of grain input. The adjustment component of the present invention adjusts the grain dispersion condition by the difference in the amount of grain accumulated in the middle and at the edge after the grain falls. When the grain accumulation weight exceeds the standard, the lifting sleeve is pressed down, driving the adjustment wheel to contact the power wheel, and the adjustment wheel moves the bottom grain, moving the bottom grain to the surrounding area. When the grain accumulation weight reaches the standard, the adjustment wheel automatically stops rotating, greatly improving the overall automation of the device. This arrangement significantly improves the flattening degree of the grain during drying, and improves the uniformity of grain drying. The grain of the present invention originally has an initial velocity away from the flattening unit, and is then subjected to the impact force of the impact column toward the flattening unit. When thrown up, a force deviation occurs between the lower and upper grains, causing the grains to be turned over. This structure achieves non-stop turning of the grains, significantly improving the drying effect of the grains. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] like Figure 2 、 Figure 3As shown, the conveying unit 2 includes a collecting hopper 21, a guide tube 22, and a guide component 23. The collecting hopper 21 and the guide tube 22 are tightly connected. The guide tube 22 is embedded in the main housing 1 and is tightly connected to the main housing 1.

[0028] like Figure 2 、 Figure 3 As shown, the guide component 23 includes a guide cone 231, a connecting column 232, a connecting pipe 233, a guide vane 234, and a mounting frame 235. The mounting frame 235 is fastened to the bottom side wall of the collecting bucket 21, the connecting pipe 233 is rotatably connected to the mounting frame 235, the connecting column 232 and the connecting pipe 233 are slidingly connected, there are two connecting columns 232, and the two connecting columns 232 are respectively located on the upper and lower sides of the connecting pipe 233. The connecting column 232 located on the upper side of the connecting pipe 233 is fastened to the guide cone 231, and the surface of the guide cone 231 is provided with spiral patterns. The connecting column 232 located on the lower side of the connecting pipe 233 is fastened to the guide vane 234. There are multiple guide vanes 234, and the multiple guide vanes 234 are evenly distributed around the connecting column 232. When the grain falls onto the guide cone 231, it will slide along the spiral lines on the guide cone 231. The lateral force during the sliding process drives the guide cone 231 to rotate, and the rotation of the guide cone 231 drives the connecting column 232 to rotate, and the connecting column 232 drives the connecting pipe 233 to rotate, and the connecting pipe 233 drives the connecting column 232 at the lower side to rotate, and the connecting column 232 at the lower side drives the guide blade 234 to rotate, so that the grain is stirred and dredged.

[0029] like Figure 6As shown, a first rack 2331, a second rack 2332, a positioning gear 2333, and a return spring 2334 are provided inside the connecting tube 233.

During the falling process of grains, the guide cone 231 will be continuously impacted by the grains. Since the falling amount of grains per unit time will fluctuate, the falling impact on the guide cone 231 will change, and the first rack 2331 will move with the change of the falling impact. The first rack 2331 and the positioning gear 2333 are engaged, driving the positioning gear 2333 to rotate, and the positioning gear 2333 drives the second rack 2332 to rotate. Then, during the downward movement of the guide cone 231, the guide vane 234 moves up accordingly, and the reset spring 2334 will push the guide cone 231 and the guide vane 234 to reset when the falling impact decreases. This structure greatly improves the smoothness of grain input.

[0030] like Figure 4 、 Figure 5 As shown, the flattening unit 3 includes a receiving groove 31, an apportionment plate 32, an adjustment groove 33, and an adjustment component 34. The receiving groove 31 and the apportionment plate 32 are fastened together. The receiving groove 31 is arranged below the guide tube 22. The apportionment plate 32 is fastened together with the side wall of the main box body 1. The apportionment plate 32 is tilted. One end of the apportionment plate 32 close to the receiving groove 31 is higher than the other end of the apportionment plate 32 away from the receiving groove 31. An installation cavity is provided inside the apportionment plate 32. The adjustment groove 33 is provided on the upper surface of the apportionment plate 32. There are multiple groups of adjustment grooves 33. The multiple groups of adjustment grooves 33 are evenly distributed along the surface of the apportionment plate 32. There are multiple groups of adjustment components 34. One end of the adjustment component 34 is located in the installation cavity, and the other end of the adjustment component 34 extends out from the adjustment groove 33. The grains fall from the guide tube 22 onto the receiving channel 31 , and the receiving channel 31 guides the grains onto the distribution plate 32 . The grains slide down along the distribution plate 32 , and the adjusting component 34 flattens the grains during the sliding process. The flattened grains are transported to the drying component 4 .

[0031] like Figure 4 、 Figure 5As shown, the adjustment component 34 includes a lifting sleeve 341, a pressure rod 342, an adjustment wheel 343, and a power wheel 344. The lifting sleeve 341 is slidingly connected to the adjustment slot 33, the adjustment wheel 343 is arranged on the inner side of the lifting sleeve 341, the adjustment wheel 343 is rotatably connected to the lifting sleeve 341, the power wheel 344 is rotatably connected to the distribution plate 32, one end of the pressure rod 342 is fastened to the lifting sleeve 341, and the other end of the pressure rod 342 is fastened to the distribution plate 32. The power wheel 344 of the present invention is provided with an independent drive. The power wheel 344 is divided into two groups from the middle position. The upper sides of the two groups of power wheels 344 rotate toward the middle position, driving the adjustment wheel 343 to be divided into two groups from the center position of the apportionment plate 32. The upper sides of the two groups of adjustment wheels 343 rotate toward the two sides of the apportionment plate 32. When the grain is transported to the apportionment plate 32, it will exert pressure on the apportionment plate 32. There is more grain on the upper side of the apportionment plate 32 at the center, and the adjustment wheel 343 here is subjected to greater pressure. The corresponding lifting sleeve 341 will press the pressure rod 342 downward. The pressure rod 342 is filled with gas, and the pressure limit can be set by adjusting the amount of gas. When the weight of the grain exceeds the standard, the pressure rod is compressed, the adjustment wheel will press on the power wheel, and the rotation of the power wheel 344 drives the adjustment wheel to rotate. The adjustment component 34 of the present invention adjusts the grain dispersion by measuring the difference in the amount of grain accumulated in the middle and at the edges after the grain has fallen. When the grain accumulation weight exceeds the standard, the lifting sleeve is pressed down, driving the adjustment wheel to contact the power wheel. The adjustment wheel moves the bottom grain, moving it toward the surrounding area. When the grain accumulation weight reaches the standard, the adjustment wheel automatically stops rotating, greatly improving the overall automation level of the device. This arrangement greatly improves the flatness of the grain during drying and improves the uniformity of the grain drying.

[0032] like Figure 8As shown, the drying component 4 includes a drying box 41, a heating plate 42, a conveyor belt 43, a setting frame 44, an impact column 45, and a driving cylinder 46. The drying box 41 is arranged inside the main box body 1, and the conveyor belt 43 is fastened to the drying box 41 through a bracket. The heating plate 42 is arranged above the conveyor belt 43, and the heating plate 42 is fastened to the upper side of the inner wall of the drying box 41. The setting frame 44 is fastened to the lower side of the inner wall of the drying box 41, and the setting frame 44 passes through the middle of the conveyor belt 43. The driving cylinder 46 is fastened to the setting frame 44, and the output shaft of the driving cylinder 46 is fastened to the impact column 45. There are multiple groups of driving cylinders 46 and impact columns 45, and the driving cylinders 46 and impact columns 45 are inclined toward the side of the flattening unit 3. The grain is conveyed by the flattening unit 3 onto the conveyor belt 43. Driven by the conveyor belt 43, the grain moves away from the flattening unit 3. During this movement, the heating plate 42 dries the grain. When the grain moves to the position corresponding to the impact column 45, the driving cylinder 46 drives the impact column 45 to impact the upper surface of the conveyor belt 43. The grain of the present invention originally has an initial velocity away from the flattening unit 3, and is then subjected to the impact force of the impact column toward the flattening unit. When thrown up, the grain on the lower side and the upper side have a force deviation, and the grain is turned over. This structure realizes the non-stop turning of the grain, greatly improving the drying effect of the grain.

[0033] like Figure 7 As shown, the detection assembly 5 includes a first setting box 51, a second setting box 52, a cover sleeve 53, an input net 54, and an output net 55. The first setting box 51, the second setting box 52 and the main box body 1 are fastened together, the cover sleeve 53 and the guide tube 22 are fastened together, the input net 54 and the output net 55 are arranged on the side wall of the guide tube 22, the cover sleeve 53 is provided with a first cavity and a second cavity, the first cavity and the input net 54 are connected, the first setting box 51 is connected with the first cavity through a pipe, the second cavity and the output net 55 are connected, the second setting box 52 is connected with the second cavity through a pipe, an air flow pump is provided inside the first setting box 51, and a humidity detector is provided inside the second setting box 52. The air flow pump and the humidity detector are both conventional technical means of those skilled in the art, and their specific structures are not described here. When the grains pass through the guide tube 22, the air flow pump will pump external air into the first cavity. The air flow enters the inside of the guide tube through the input net 54, and enters the second cavity from the output net 55 with moisture on the surface of the grains. The air flow inside the second cavity is transported to the humidity detector, which detects the humidity of the air flow and controls the drying time according to the humidity of the air flow. For grains with higher humidity, the drying time is increased.

[0034] The present invention operates as follows: When grain falls onto guide cone 231, it slides along the spiral lines of guide cone 231. The lateral force generated during this sliding process drives guide cone 231 to rotate, which in turn drives connecting post 232 to rotate connecting tube 233. Connecting tube 233 drives connecting post 232 located below to rotate, which in turn drives guide vanes 234 to rotate, thereby stirring and dredging the grain. As the grain falls and passes through guide tube 22, an air pump pumps external air into the first cavity. This airflow enters the guide tube through input mesh 54, carrying moisture from the grain surface into the second cavity through output mesh 55. The airflow within the second cavity is then transported to a humidity detector, which measures the humidity of the airflow and controls the drying time accordingly, increasing the drying time for grains with higher humidity. The grains fall from the guide tube 22 onto the receiving chute 31, which guides them onto the distribution plate 32. The grains slide down the distribution plate 32, and during the sliding process, the adjustment component 34 flattens the grains. The flattened grains are then conveyed to the drying assembly 4. The grains are conveyed by the flattening unit 3 onto the conveyor belt 43. Driven by the conveyor belt 43, the grains move away from the flattening unit 3. During this movement, the heating plate 42 dries the grains. When the grains move to the corresponding position of the impact column 45, the driving cylinder 46 drives the impact column 45 to strike the upper surface of the conveyor belt 43, turning the grains over, and the dried grains are discharged.
