Technical Field
[0001] This utility model relates to the technical field of drying grains, and in particular to a grain drying device with automatic discharge function. Background Technology
[0002] After farmers harvest the grains from the fields (including cereals, beans, etc.), they need to use a dryer to dry them. The purpose of drying is to reduce the moisture content of the grains, reduce the loss of nutrients in the grains, and thus extend the storage period of the grains.
[0003] A certain region adopts, such as Figures 1-2 The dryer shown is used to dry grains. The dryer includes a drying cabinet 1 with an opening on the right side. Multiple mesh panels 2 are fixedly installed at intervals along the height of the drying cabinet 1. A horizontally arranged electric cylinder 3 is fixedly installed on the bottom surface of the drying cabinet 1. The piston rod of the electric cylinder 3 extends to the right outside the drying cabinet 1, and a cabinet door 4 is fixedly installed on the extended end. The cabinet door 4 is opposite to the opening of the drying cabinet 1. An air inlet pipe 5 is connected to the left side wall of the drying cabinet 1. The air inlet pipe 5 is located below the bottom mesh panel 2. An air heater 6 and a blower 7 are sequentially connected to the other end of the air inlet pipe 5. An exhaust pipe 8 is connected to the top wall of the drying cabinet 1, and a condenser is connected to the other end of the exhaust pipe 8.
[0004] The method workers use this dryer to dry grains is as follows:
[0005] S1. Workers spread the grains to be dried evenly on the top surface of each mesh plate 2, thereby feeding the grains.
[0006] S2. The worker controls the piston rod of the opening / closing electric cylinder 3 to retract to the left. The piston rod drives the cabinet door 4 to move to the left, and the cabinet door 4 moves towards the opening of the drying cabinet 1. When the piston rod of the opening / closing electric cylinder 3 is fully retracted, the cabinet door 4 seals the opening of the drying cabinet 1. Figure 3 As shown, at this time, the grains on each mesh plate 2 are sealed between the drying cabinet 1 and the cabinet door 4;
[0007] S3. The worker controls the start of blower 7 and air heater 6. Blower 7 draws outside air into air heater 6, which heats the air. The heated air enters the drying cabinet 1 through air inlet pipe 5. The hot air then passes upward through the mesh of mesh plate 2 and the gaps between grains, and finally enters the condenser through exhaust pipe 8. When the hot air passes through the gaps between grains, it raises the surface temperature of the grains, causing the moisture in the grains to turn into water vapor. The water vapor then enters the condenser with the hot air.
[0008] S4. After the blower 7 has been working for a period of time, the worker turns off the blower 7 and the air heater 6, thus finally achieving the drying of the grain.
[0009] S5. Discharging the dried grain: The worker controls the piston rod of the electric cylinder 3 to extend to the right. The piston rod drives the cabinet door 4 to move to the right, moving the cabinet door 4 away from the drying cabinet 1. When the piston rod of the electric cylinder 3 is fully extended, the worker removes the dried grain from the mesh plate 2 through the opening of the drying cabinet 1, in the following direction: Figure 4 As indicated by the hollow arrow, this allows for the discharge of the dried grains.
[0010] S6. Workers can repeat steps S1 to S5 multiple times to dry grains continuously in multiple batches.
[0011] However, although this type of dryer is usable, it still has the following technical defects:
[0012] In step S3, after all the grains are dried, workers need to manually remove the dried grains from the opening of the drying cabinet 1. The more mesh plates 2 there are, the more grains need to be removed. Manually removing the dried grains not only increases the workload of the workers, but also prolongs the drying time for the next batch of grains. As a result, it takes a long time to dry all the harvested grains, which is a technical defect of low drying efficiency.
[0013] Therefore, there is an urgent need for a grain drying device that can greatly reduce the workload of workers and greatly improve the efficiency of grain drying. Utility Model Content

[0042] The present invention will be further described below with reference to the accompanying drawings. The scope of protection of the present invention is not limited to the following description:
[0043] like Figures 5-10As shown, a grain drying device with automatic discharge function includes a drying cabinet 1. The drying cabinet 1 has an opening on its right side. The left side wall of the drying cabinet 1 has multiple through slots 9 connected to the opening along its height direction. A lifting electric cylinder 10 is fixed on the left side wall at the upper end of the drying cabinet 1. A baffle plate 11 is fixed on the piston rod of the lifting electric cylinder 10. The baffle plate 11 is in contact with the left side wall of the drying cabinet 1. Multiple discharge slots 12 are opened in the baffle plate 11 along its height direction. The discharge slots 12 are staggered from the through slots 9.
[0044] A horizontally arranged electric cylinder 3 is fixed on the bottom surface of the drying cabinet 1. The piston rod of the electric cylinder 3 extends to the right outside the drying cabinet 1, and a cabinet door 4 opposite to the opening is fixed on the extended end. An air inlet pipe 5 is connected to the left side wall of the drying cabinet 1. The air inlet pipe 5 is located below the lowest through groove 9. An air heater 6 and a blower 7 are sequentially connected to the other end of the air inlet pipe 5. An exhaust pipe 8 is connected to the top wall of the drying cabinet 1. A condenser is connected to the other end of the exhaust pipe 8.
[0045] On the left side wall of the cabinet door 4, multiple loading and unloading assemblies 13 are arranged along its height direction, each facing the through groove 9. The lowest loading and unloading assembly 13 includes a support plate 14 fixed to the left side wall of the cabinet door 4, a bearing plate 15 hinged to the support plate 14, and an unloading electric cylinder 16 fixed to the right side wall of the cabinet door 4. The bearing plate 15 extends to the left, and a U-shaped groove 17 is formed on the extended end. A mesh plate 2 is fixed to the bottom surface of the bearing plate 15 directly below the U-shaped groove 17. The unloading electric cylinder 16 penetrates the cabinet door 4 to the left, and a connecting rod 18 is hinged to the extended end. The other end of the connecting rod 18 is hinged to the bottom surface of the bearing plate 15. A hinge seat 19 is fixed to the top surface of the support plate 14, and the right end of the bearing plate 15 is hinged to the hinge seat 19 via a pin.
[0046] Two support columns, which are supported on the ground, are fixed on the bottom surface of the drying cabinet 1, and the opening and closing electric cylinder 3 is fixed between the two support columns. A fixing plate is welded to the left side wall at the upper end of the drying cabinet 1, and the cylinder body of the lifting electric cylinder 10 is fixed on the top surface of the fixing plate, with the piston rod of the lifting electric cylinder 10 penetrating downward through the fixing plate.
[0047] The grain drying device also includes a controller, which is connected to the lifting cylinder 10, the unloading cylinder 16 and the opening and closing cylinder 3 via electrical signals. The operator can control the extension and retraction of the piston rods of the lifting cylinder 10, the unloading cylinder 16 and the opening and closing cylinder 3 through the controller, thereby facilitating the operator's operation.
[0048] The method for drying grains according to this invention is as follows:
[0049] S1. Workers spread the grains to be dried evenly on the top surface of each mesh plate 2. At this time, the grains are confined within the U-shaped groove 17 of the bearing plate 15, thereby realizing the feeding of the grains.
[0050] S2. The worker controls the piston rod of the opening and closing electric cylinder 3 to retract to the left. The piston rod drives the cabinet door 4 to move to the left, and the cabinet door 4 moves towards the opening of the drying cabinet 1. The cabinet door 4 drives each loading and unloading component 13 to move to the left synchronously. When the piston rod of the opening and closing electric cylinder 3 is fully retracted, the left ends of the mesh plates 2 of each loading and unloading component 13 enter the respective through slots 9. Figure 11 As shown, the cabinet door 4 blocks the opening of the drying cabinet 1. At this time, the grains on each mesh plate 2 are sealed between the drying cabinet 1 and the cabinet door 4.
[0051] S3. The worker controls the start of blower 7 and air heater 6. Blower 7 draws outside air into air heater 6, which heats the air. The heated air enters the drying cabinet 1 through air inlet pipe 5. The hot air then passes upward through the mesh of mesh plate 2 and the gaps between grains, and finally enters the condenser through exhaust pipe 8. When the hot air passes through the gaps between grains, it raises the surface temperature of the grains, causing the moisture in the grains to turn into water vapor. The water vapor then enters the condenser with the hot air.
[0052] S4. After the blower 7 has been working for a period of time, the worker turns off the blower 7 and the air heater 6, thus finally achieving the drying of the grain.
[0053] S5. The specific steps for removing the dried grains are as follows:
[0054] S51, the piston rod of the lifting cylinder 10 retracts upward, causing the baffle plate 11 to move upward. The baffle plate 11 then moves each discharge chute 12 within it upward synchronously. When the piston rod of the lifting cylinder 10 is fully retracted, each discharge chute 12 within the baffle plate 11 is connected to each corresponding through slot 9 of the drying cabinet 1. Figure 12 As shown;
[0055] S52. The worker takes out a receiving box 20 and places it against the left side wall of the drying cabinet 1. Figure 13 As shown, ensure that the receiving box 20 is positioned below the baffle plate 11.
[0056] S53. The piston rod of the unloading electric cylinder 16, which controls each loading and unloading assembly 13, extends to the left. The piston rod drives the connecting rod 18 to move to the left. The connecting rod 18 drives the bearing plate 15 to rotate counterclockwise around the hinge seat 19. When the piston rod of the unloading electric cylinder 16 is fully extended, both the bearing plate 15 and the mesh plate 2 are in an inclined state. Figure 14As shown, at this time, the dried grains on the mesh plate 2 slide downwards along the mesh plate 2 under their own gravity, and the sliding direction of the dried grains is as follows. Figure 14 As shown by the hollow arrow, the dried grains sliding down from the mesh plate 2 pass through the through groove 9 and the discharge groove 12 in sequence, and finally fall into the receiving box 20, thus completing the discharge of the dried grains.
[0057] S6. Workers can repeat steps S1 to S5 multiple times to dry grains continuously in multiple batches.
[0058] As can be seen from steps S3 to S5, after the harvested grains are dried, the piston rod of the lifting cylinder 10 is first controlled to retract upward so that the discharge trough 12 in the baffle plate 11 is connected to the through groove 9 of the drying cabinet 1. Then, the piston rod of the discharge cylinder 16 of each loading and unloading component 13 is controlled to extend, so that the bearing plate 15 and the screen plate 2 are tilted, thereby automatically collecting the dried grains on the screen plate 2 into the receiving box 20, thus finally realizing the automatic removal of the dried grains.
[0059] Therefore, it can be seen that this grain drying device is superior to... Figures 1-4 The dryer shown eliminates the need for workers to manually retrieve dried grains from the opening of the drying cabinet 1, greatly reducing their workload. Furthermore, this grain drying device simultaneously collects all dried grains from each mesh plate 2 into the receiving box 20, compared to... Figures 1-4 The dryer shown eliminates the need for workers to manually remove the dried grains from the mesh 2 one by one, thus shortening the drying time for the next batch of grains. This allows all the harvested grains to be dried in a short time, greatly improving the drying efficiency of the grains.
