Technical Field

[0001] This utility model relates to the field of grain drying, specifically a high-efficiency and energy-saving grain drying device. Background Technology

[0002] After harvesting, grains need to be stored, and drying is a key step in proper storage. The main purpose of grain drying is to reduce the moisture content of the grains, prevent mold, sprouting, and losses during storage, and ensure the safety and quality of the grains.

[0003] For specific details regarding existing grain drying devices, please refer to a high-efficiency and energy-saving grain dryer disclosed in application number CN202022434144.1. This dryer includes a base, with a support plate fixedly connected to the top of the base via a support column. A conveying shell is located on the top of the support plate, and a conveying motor is fixedly installed at one end of the conveying shell. An auger, rotatably connected to the conveying motor, is installed inside the conveying shell. A discharge pipe is located at the bottom of the end of the conveying shell opposite the conveying motor, and the discharge pipe penetrates the support plate. A feed hopper is located on the top of the conveying shell near the conveying motor, and a heating tube is installed at the top of the inner cavity of the conveying shell. A flow-limiting plate is inclined inside the discharge pipe, and an exhaust port is opened on the side of the discharge pipe away from the support column. An impurity removal device is connected to the outer end of the exhaust port. This invention improves the efficiency of grain drying and recovery, and reduces the impurity content in the grain during the drying and recovery process.

[0004] In the aforementioned grain drying device, the grain tends to accumulate during the drying process, making it impossible to dry all the grain evenly. After the grain leaves the dryer, some grain still contains moisture, so it needs to be dried again. This results in very low grain drying efficiency and consumes a large amount of electricity. Utility Model Content

[0005] To address the shortcomings of existing technologies, current grain drying devices often result in grain accumulation during the drying process, making it impossible to dry all the grain evenly. After the grain leaves the dryer, some grain still contains moisture, requiring further drying. This leads to very low drying efficiency and consumes a large amount of electricity. This invention proposes a highly efficient and energy-saving grain drying device.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The high-efficiency and energy-saving grain drying device of this utility model includes a drying box, a feed inlet fixedly connected to the top of the drying box, multiple drying holes opened inside the drying box, a reciprocating mechanism provided at the front and rear of the drying box, the reciprocating mechanism including a cam, the cam being provided at the front and rear of the drying box, a driven wheel being provided at the top of the cam, a support rod being fixedly connected to the top of the driven wheel, long grooves being opened at the front and rear of the drying box, a connecting rod being provided inside the long grooves, a vibrating plate being provided inside the drying box, the front and rear of the vibrating plate being fixedly connected to one end of two sets of connecting rods, and the other end of the connecting rods being fixedly connected to the top of the support rod.

[0007] Preferably, a guide block is sleeved on the outside of the support rod, and the guide block is fixedly connected to the drying box.

[0008] Preferably, the drying box has mounting slots at the front and rear, and a transmission mechanism is provided inside the mounting slot. The transmission mechanism includes a rotating column, which is rotatably connected to the inside of the mounting slot. A rotating rod is rotatably connected inside the drying box on the side near the mounting slot. Both ends of the rotating rod pass through the mounting slot. A transmission belt is sleeved on the outer side of one end of the rotating column and the rotating rod, and the transmission belt meshes with the rotating column and the rotating rod.

[0009] Preferably, a protective shell is fixedly connected inside the mounting groove, the output shaft of the rotating column near the cam passes through the protective shell and is fixedly connected to the cam, and a motor is provided at the front of the drying box, the output shaft of the motor passes through the protective shell and is fixedly connected to one end of the rotating rod.

[0010] Preferably, the drying box has discharge troughs on both sides, positioning troughs on both sides, a blocking block inside the discharge trough, a positioning block inside the positioning trough, the positioning block and the blocking block being fixedly connected, a threaded hole inside the positioning trough, a through hole inside the positioning block, a screw inside the through hole, and the screw passing through the through hole and threadedly connected to the threaded hole.

[0011] Preferably, inclined plates are provided on both sides of the top of the vibration plate, and the two sets of inclined plates are fixedly connected to the top of the vibration plate.

[0012] Preferably, the bottom of the drying box is provided with a placement slot, and two sets of fans are fixedly connected inside the placement slot.

[0013] The advantages of this utility model are:

[0014] This invention, through the structural design of a reciprocating mechanism and a transmission mechanism, enables grain drying. When grain needs to be dried, it is fed into the top of the vibrating plate inside the drying chamber through the inlet. The drying chamber is then opened, and hot air is blown through the drying holes to dry the grain. However, because the grain accumulates on top of the vibrating plate, the hot air cannot reach the grain piled inside, resulting in uneven drying. Therefore, a motor is activated to drive the connected rotating rod, which in turn drives the two sets of transmission belts and rotating columns at both ends of the rotating rod. This simultaneously drives two sets of cams to rotate. The cam's structural design ensures that, under the action of gravity, the driven wheel at the top of the cam rotates. The machine continuously moves along the outer side of the cam, reciprocating up and down, which in turn drives the support rod, connecting rod, and vibrating plate at the top of the driven wheel to move up and down again. This vibrating plate vibrates the grain at the top, allowing the hot air to dry the grain evenly. This solves the problem in current grain drying devices where grain tends to pile up, making it impossible to dry all the grain evenly. After the grain leaves the dryer, some grain still contains moisture and needs to be dried again, resulting in very low drying efficiency and high power consumption. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figure 1 - Figure 4 As shown, a high-efficiency and energy-saving grain drying device includes a drying box 1, a feed inlet 2 fixedly connected to the top of the drying box 1, multiple drying holes 3 opened inside the drying box 1, a reciprocating mechanism provided at the front and rear of the drying box 1, the reciprocating mechanism including a cam 4, the cam 4 is provided at the front and rear of the drying box 1, a driven wheel 5 is provided at the top of the cam 4, a support rod 6 is fixedly connected to the top of the driven wheel 5, long grooves 7 are opened at the front and rear of the drying box 1, a connecting rod 8 is provided inside the long groove 7, a vibrating plate 9 is provided inside the drying box 1, the front and rear of the vibrating plate 9 are fixedly connected to one end of two sets of connecting rods 8, and the other end of the connecting rods 8 is fixedly connected to the top of the support rod 6;

[0023] During operation, when grain drying is required, the grain is fed into the top of the vibrating plate 9 inside the drying chamber 1 through the feed inlet 2. The drying chamber 1 is then turned on, and hot air is blown through the drying holes 3 to dry the grain. Since the grain is piled up on top of the vibrating plate 9, the hot air cannot dry the grain piled up inside, and the grain cannot be dried evenly. Therefore, the motor 16 is turned on to drive the rotating rod 13 connected to it to rotate, which in turn drives the two sets of transmission belts 14 and rotating column 12 at both ends of the rotating rod 13 to rotate, thereby simultaneously driving the two sets of cams 4 to rotate. The structural design of the cam 4 causes the driven wheel 5 at the top of the cam 4 to move continuously along the outside of the cam 4 under the action of gravity when it rotates, that is, to move back and forth. This drives the support rod 6, connecting rod 8 and vibrating plate 9 at the top of the driven wheel 5 to move back and forth. In this way, the vibrating plate 9 will vibrate the grain at the top, so that the hot air can dry the grain evenly.

[0024] Furthermore, such as Figure 1As shown, a guide block 10 is sleeved on the outside of the support rod 6, and the guide block 10 is fixedly connected to the drying box 1;

[0025] During operation, the guide block 10 restricts the position of the support rod 6 and the driven wheel 5, so that the support rod 6 and the driven wheel 5 can only move up and down and will not disengage from the top of the cam 4.

[0026] Furthermore, such as Figure 2 As shown, the drying box 1 has mounting slots 11 at the front and rear. A transmission mechanism is installed inside the mounting slot 11. The transmission mechanism includes a rotating column 12, which is rotatably connected to the inside of the mounting slot 11. A rotating rod 13 is rotatably connected inside the drying box 1 on the side near the mounting slot 11. Both ends of the rotating rod 13 pass through the mounting slot 11. A transmission belt 14 is sleeved on the outer side of one end of the rotating column 12 and the rotating rod 13. The transmission belt 14 meshes with the rotating column 12 and the rotating rod 13.

[0027] During operation, since both ends of the vibrating plate 9 are connected to two sets of reciprocating mechanisms via connecting rods 8, to ensure that the vibrating plate 9 is parallel to the bottom of the drying box 1 and rises and falls, it is necessary to ensure that the two sets of cams 4 rotate simultaneously and at the same speed under the same initial state. To avoid errors, a rotating rod 13 with rotating columns 12 is designed. When the motor 16 is turned on, it drives the rotating rod 13 connected to it to rotate, thereby driving the two sets of transmission belts 14 and rotating columns 12 at both ends of the rotating rod 13 to rotate, thereby simultaneously driving the two sets of cams 4 to rotate. The transmission belt 14 meshes with the rotating column 12 and the rotating rod 13 to prevent the transmission belt 14 from slipping on the rotating column 12 and the rotating rod 13.

[0028] Furthermore, such as Figure 2 As shown, a protective shell 15 is fixedly connected inside the mounting slot 11. The output shaft of the rotating column 12 on the side near the cam 4 passes through the protective shell 15 and is fixedly connected to the cam 4. A motor 16 is provided at the front of the drying box 1. The output shaft of the motor 16 passes through the protective shell 15 and is fixedly connected to one end of the rotating rod 13.

[0029] When in operation, the motor 16 drives the rotating rod 13 connected to it to rotate, and the protective shell 15 can prevent outsiders from touching the transmission mechanism.

[0030] Furthermore, such as Figure 2 As shown, the drying box 1 has discharge troughs 17 on both sides, and positioning grooves 18 on both sides of the discharge troughs 17. A blocking block 19 is provided inside the discharge trough 17, and a positioning block 20 is provided inside the positioning groove 18. The positioning block 20 is fixedly connected to the blocking block 19. A threaded hole 21 is provided inside the positioning groove 18, and a through hole 22 is provided inside the positioning block 20. A screw 23 is provided inside the through hole 22, and the screw 23 passes through the through hole 22 and is threadedly connected to the threaded hole 21.

[0031] When the grain drying process is finished, remove the screws 23 on both sides of the drying box 1 from the threaded holes 21, and remove the block 19 from the discharge trough 17 to allow the grain to be discharged. When the grain drying process is to continue, the block 19 needs to be reinstalled in the discharge trough 17, and the positioning blocks 20 at both ends of the block 19 need to be inserted into the positioning slots 18. The screws 23 are threaded through the through holes 22 and threaded into the threaded holes 21 to fix the block 19.

[0032] Furthermore, such as Figure 3 As shown, inclined plates 24 are provided on both sides of the top of the vibrating plate 9, and the two sets of inclined plates 24 are fixedly connected to the top of the vibrating plate 9.

[0033] During operation, after the drying process is completed and the blockage block 19 is removed, the height of the vibrating plate 9 is lowered by the motor 16, so that the grain on the vibrating plate 9 slides on the inclined plate 24 to the discharge troughs 17 on both sides. The two sets of inclined plates 24 are placed symmetrically on the vibrating plate 9, so that the grain can be appropriately distributed and slide out from the top sides of the vibrating plate 9, preventing too much grain from directly rushing out of the discharge trough 17.

[0034] Furthermore, such as Figure 3 As shown, a placement slot 25 is provided at the bottom of the drying oven 1, and two sets of fans 26 are fixedly connected inside the placement slot 25;

[0035] During operation, when the dried grain on the vibrating plate 9 falls into the discharge trough 17, the blower 26 is turned on. The blower 26 blows out at a low speed, which will blow out the fragments of the dried grain. Then the dried grain can be collected.

[0036] Working principle: When grain drying is required, the grain is fed into the top of the vibrating plate 9 inside the drying chamber 1 through the feed inlet 2. The drying chamber 1 is turned on and hot air is blown through the drying holes 3 to dry the grain. Since the grain is piled up on top of the vibrating plate 9, the hot air cannot dry the grain piled up inside, and the grain cannot be dried evenly. Therefore, the motor 16 is turned on to drive the rotating rod 13 connected to it to rotate, which in turn drives the two sets of transmission belts 14 and rotating column 12 at both ends of the rotating rod 13 to rotate, thereby simultaneously driving the two sets of cams 4 to rotate. The structural design of the cam 4 makes it so that when it rotates, under the action of gravity, the driven wheel 5 at the top of the cam 4 continuously moves along the outer side of the cam 4. The movement, i.e., the reciprocating lifting and lowering motion, drives the support rod 6, connecting rod 8, and vibrating plate 9 at the top of the driven wheel 5 to reciprocate and lift. In this way, the vibrating plate 9 vibrates the grain at the top, so that the hot air can dry the grain evenly. When the grain drying work is finished, the screws 23 on both sides of the drying box 1 are removed from the threaded holes 21, the block 19 is removed from the discharge chute 17, and the height of the vibrating plate 9 is lowered by starting the motor 16, so that the grain on the vibrating plate 9 slides on the inclined plate 24 to the discharge chute 17. The fan 26 is turned on. The fan 26 blows out the debris of the dried grain at a low speed. Then the dried grain can be collected.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
