Description

Technical Field

[0001] This disclosure relates to the field of grain drying equipment technology, and in particular to a residue-free drying device. Background Technology

[0002] Current grain drying equipment uses multiple stacked drying layers. Grain falls freely from the top, passes through multiple drying layers for drying, and then falls to the bottom discharge mechanism for unloading. This process is repeated multiple times until the grain is completely dried.

[0003] Because the grain cannot fall directly onto the conveyor auger during the falling process to avoid excessive grain accumulation that could jam the auger, the grain needs to be transported to the conveyor auger via a grain-discharging wheel after it falls to the bottom. The grain-discharging wheel moves the grain by rotating, and some grain in the corners may remain, preventing some grain from entering the conveyor auger and thus preventing complete discharge. Utility Model Content

[0004] This disclosure provides a residue-free drying apparatus to solve the technical problems recognized by the inventors.

[0005] This disclosure provides a residue-free drying apparatus, including at least one drying layer, each of which includes a plurality of drying chambers arranged in parallel.

[0006] The discharge bin includes a hopper, a baffle plate, a grain feeding mechanism, and a discharge mechanism. The hopper is located at the bottom of the drying chamber and is connected to it. Two baffle plates are movably connected to the middle of the hopper. The grain feeding mechanism is located above the baffle plate to transfer the material to the discharge mechanism. A discharge port is provided at the bottom of the hopper, and the discharge mechanism is located at the bottom of the hopper to transfer the material to the discharge port for discharge.

[0007] Preferably, one end of the baffle plate is hinged to the inner side of the hopper, and the other end of the baffle plate is connected to a first connecting rod. The end of the first connecting rod away from the baffle plate is hinged to a second connecting rod, and the end of the second connecting rod away from the first connecting rod is hinged to a third connecting rod. The end of the third connecting rod away from the second connecting rod is hinged to the upper part of the hopper.

[0008] Preferably, the grain feeding mechanism includes a grain feeding motor and two grain feeding wheels. The two grain feeding wheels are rotatably connected above the baffle plate, and the grain feeding motor is driven by the two grain feeding wheels to drive them to rotate.

[0009] Preferably, the discharge mechanism includes a discharge motor and a conveying auger, the conveying auger being rotatably connected to the bottom of the hopper, and the discharge motor being drively connected to the conveying auger to drive the conveying auger to rotate.

[0010] Preferably, the hopper also includes a diverter plate with an inverted "V" shaped cross-section. The diverter plate is located in the middle of the hopper and is used to divert the material to baffles located on both sides of the hopper.

[0011] Preferably, the drying box has multiple corner boxes evenly distributed inside, and the surfaces of the corner boxes are inclined along the direction close to the grain discharge bin.

[0012] Preferably, the corner box includes several columns, with corner boxes in odd-numbered columns and corner boxes in even-numbered columns arranged alternately.

[0013] Preferably, the corner box located in the odd-numbered column has an air inlet at one end, and the corner box located in the even-numbered column has an air outlet at the end away from the air inlet.

[0014] Preferably, a baffle plate is provided on the outside of the drying box above the air inlet, and the baffle plate is inclined along the direction of the discharge bin.

[0015] The main beneficial effects of this invention are as follows: By setting a movable baffle plate in the bottom hopper, after all the grain has been transferred to the discharge mechanism by the grain feeding mechanism, the remaining grain on the baffle plate can be slid down into the discharge mechanism for discharge by rotating the baffle plate, thus avoiding residual grain and achieving residue-free drying.

[0028] Example

[0029] like Figure 1-5 As shown, this embodiment provides a residue-free drying device, including at least one drying layer 100. The drying layer 100 can be configured in multiple layers as needed, and the multiple drying layers 100 are stacked sequentially from top to bottom. Each drying layer 100 includes several drying boxes 101 arranged in parallel. The drying boxes 101 are open at both the top and bottom, so that the grain can fall from the top drying box 101 and be dried during the falling process. The bottom drying layer 100 is connected to a discharge bin 200, and the dried grain enters the discharge bin 200 for discharge.

[0030] Specifically, the discharge hopper 200 includes a hopper 201, baffle plates 202, a grain feeding mechanism 203, and a discharge mechanism 204. The feed end of the hopper 201 is connected to the discharge end of the drying box 101 located at the bottom. Baffle plates 202 are hinged to both sides of the middle part of the hopper 201. The two baffle plates 202 block the falling grain and act as a platform for the grain, preventing the grain from falling directly and accumulating on the discharge mechanism 204, which would cause a large amount of grain to accumulate and block the discharge mechanism 204, resulting in the inability to discharge normally. The grain feeding mechanism 203... 03 is set above the baffle plate 202 and is used to convey the grain on the baffle plate 202 to the discharge mechanism 204. After the grain conveying mechanism 203 conveys the grain on the baffle plate 202 to the discharge mechanism 204, the discharge mechanism 204 conveys the grain. A discharge port is opened at one end of the bottom of the discharge bin 200. After the grain is transported to the discharge port, it falls down with the channel and is transferred to the elevator. The elevator transports the grain back to the top drying layer 100 and discharges it again. This process is repeated multiple times until the grain is completely dried.

[0031] Furthermore, in this embodiment, an opening is provided on each side of the hopper 201. One end of the baffle plate 202 is rotatably connected to the hopper 201 above the opening via a hinge structure. The other end of the baffle plate 202 is hinged to a first connecting rod 2021 via a hinge structure. The end of the first connecting rod 2021 away from the baffle plate 202 is hinged to a second connecting rod 2022. The end of the second connecting rod 2022 away from the first connecting rod 2021 is hinged to a third connecting rod 2023. The end of the third connecting rod 2023 away from the second connecting rod 2022 is hinged to the upper part of the hopper 201. The baffle plate 202 is initially parallel to the horizontal plane. At this time, the baffle plate 202 can catch the falling grain. When the grain stops falling, the second and third connecting rods 2023 can be manually pulled to fold them. At this time, the first connecting rod 2021 moves away from the hopper 201, pulling the baffle plate 202 to rotate, and the grain remaining on the baffle plate 202 slides into the discharge mechanism 204 for discharge, achieving zero-residue discharge.

[0032] Specifically, the grain dispensing mechanism 203 includes a grain dispensing motor 2031 and two grain dispensing wheels 2032. The grain dispensing motor 2031 is fixedly mounted on the discharge bin 200 by bolts. The two grain dispensing wheels 2032 are rotatably connected above the baffle plate 202. A sprocket is fixedly connected to the end of each grain dispensing wheel 2032. The grain dispensing motor 2031 is connected to the sprockets of the two grain dispensing wheels 2032 by a chain to drive the two grain dispensing wheels 2032 to rotate. The main body of the grain dispensing wheel 2032 is cylindrical, and multiple blades are integrally formed on the side. The length direction of the grain dispensing wheel 2032 is the same as the length direction of the baffle plate 202. By rotating the grain dispensing wheel 2032, the blades push the grain on the baffle plate 202 into the discharge mechanism 204 for discharge.

[0033] Specifically, the discharge mechanism 204 includes a discharge motor 2041 and a conveying auger 2042. The discharge motor 2041 is fixedly installed on the discharge bin 200 by bolts. The conveying auger 2042 is rotatably connected to the bottom of the hopper 201. A sprocket is connected to the end of the conveying auger 2042. The discharge motor 2041 is connected to the conveying auger 2042 via a chain for driving the conveying auger 2042 to rotate. The grain falls to the bottom of the grain bin. During the rotation, the conveying auger 2042 can transport the grain towards the discharge port. After being transported to the discharge port, the grain is discharged from the discharge port.

[0034] Furthermore, it also includes a diversion plate 205, which has an inverted "V" shaped cross-section. The diversion plate 205 is located in the middle of the hopper 201 and is used to divert the material to the baffle plates 202 located on both sides of the hopper 201. In order to prevent the grain falling in the middle of the hopper 201 from directly entering the discharge mechanism 204, the diversion plate 205 blocks the grain falling in the middle. The grain rolls down along both sides of the diversion plate 205 into the baffle plate 202, so that the grain can fall onto the baffle plate 202 first.

[0035] In one embodiment, a plurality of corner boxes 102 are evenly distributed inside the drying chamber 101, and the surface of the corner boxes 102 is inclined along the direction close to the grain discharge bin. When the grain falls, it passes through the corner boxes 102, which can slow down the falling speed of the grain and separate the grain so that it can be dried more thoroughly. In this embodiment, the corner box 102 located in the middle has a triangular cross-section, and the corner box 102 located at the edge has a right-angled triangular cross-section. This arrangement is to allow the corner boxes 102 to be installed at the edge as well. Traditionally, the corner boxes 102 are only installed in the middle of the drying chamber 101, and are not installed at the edge due to the shape of the corner boxes 102, so that the corner boxes 102 cannot be evenly distributed at the edge of the drying chamber 101.

[0036] Furthermore, the corner box 102 includes several columns, with the corner boxes 102 in odd-numbered columns and those in even-numbered columns arranged alternately. The corner boxes 102 are arranged in multiple columns from top to bottom along the height direction of the drying box 101, and are arranged alternately, so that the grain can be blocked and buffered by the corner boxes 102 to the maximum extent, reducing the falling speed of the grain and making the grain more dispersed during the falling process, thereby improving the drying efficiency.

[0037] Furthermore, the corner boxes 102 located in the odd-numbered columns have an air inlet 103 at one end, and the corner boxes 102 located in the even-numbered columns have an air outlet 104 at the end away from the air inlet 103. The air inlet 103 is connected to the channel for conveying hot air, and the air outlet 104 is used to discharge the airflow inside the drying chamber 101. With air entering at one end and exiting at the other, the airflow distribution inside the drying chamber 101 is more uniform, improving the drying effect.

[0038] Furthermore, a baffle plate 105 is installed on the outside of the drying chamber 101 above the air inlet 103, and the baffle plate 105 is inclined along the direction of the discharge hopper 200. The warm air blows from bottom to top, and after being blocked by the baffle plate 105, the warm air can be guided into the air inlet 103, thereby improving the drying efficiency.

[0039] The working principle of this utility model is as follows: Grain is transported to the top drying layer 100 by an elevator (not shown in the figure). The grain is then introduced into the top drying box 101. At the same time, hot air is injected into the drying box 101 through the air inlet 103. During the fall, the grain is buffered and diverted by the corner box 102, which disperses it and allows it to fall gradually, drying it during the fall. After passing through multiple drying layers 100, the grain enters the discharge hopper 200. The diverter plate 205 divides the grain onto the baffle plates 202 on both sides of the hopper 201. The grain feeding motor 2031 is started to drive the two grain feeding wheels 2032 to rotate synchronously. During the rotation of the grain feeding wheels 2032, hot air is continuously supplied. The grain is conveyed to the bottom of the hopper 201 by the blades on the grain feeding wheel 2032. The discharge motor 2041 is started, driving the conveying auger 2042 to rotate. The conveying auger 2042 conveys the grain along the direction of the discharge port, allowing the grain to be discharged from the discharge port. When the grain feeding mechanism 203 can no longer convey grain into the discharge mechanism, the grain feeding motor 2031 is turned off. The second and third connecting rods 2023 are manually pulled to fold them. At this time, the first connecting rod 2021 moves away from the hopper 201, pulling the baffle plate 202 to rotate, causing the grain remaining on the baffle plate 202 to slide into the discharge mechanism 204 for discharge, achieving residue-free discharge. The above steps can be repeated multiple times until all the grain is dried.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure, and are not intended to limit them. Although this disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this disclosure.
