Description

Technical Field

[0001] This utility model relates to the field of grain drying technology, and in particular to a quantitative feeding device for a grain dryer. Background Technology

[0002] Before grains are stored in granaries, they need to be dried to reduce their moisture content. Currently, the main methods for drying grains are sun-drying or using dryers. Sun-drying is easily affected by the weather. If the grains are not dried sufficiently, the internal humidity can easily cause them to mold and deteriorate. Poor drying results can affect the subsequent storage of the grains.

[0003] However, in the grain dryer of the relevant technology, the flow rate of grain cannot be well controlled during the drying process, which makes it inconvenient to feed and discharge quantitatively. This causes the grain to accumulate and not be dried properly, thus affecting the drying effect. Therefore, we propose a quantitative feeding device for a grain dryer to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a quantitative feeding device for a grain dryer, which allows for intermittent control of the grain feeding flow, enabling the grain to be quantitatively fed between the partitions for layered drying. This increases the contact area between the grain and the hot air, prolongs the contact time, avoids the situation where some grain is not dried, and greatly improves the drying effect and efficiency of the grain.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a quantitative feeding device for a grain dryer, applied to a grain drying machine box, wherein four partitions are fixedly connected inside the machine box, a quantitative feeding mechanism is provided between the machine box and the four partitions, a stirring mechanism is provided on the machine box, a hot air fan is fixedly connected to the bottom of one side of the machine box, and a feeding hopper is fixedly connected to the top of the machine box.

[0006] A further feature of this invention is as follows: the quantitative feeding mechanism includes four sliding rods slidably disposed on both sides of the chassis, and a support plate fixedly connected to one side of the chassis. A drive motor is fixedly connected to the rear side of the support plate. A drive gear and a driven gear are rotatably connected sequentially from left to right on the front side of the support plate. The output shaft of the drive motor is fixedly connected to the rear side of the drive gear. The drive gear and the driven gear mesh. A drive column is fixedly connected to the front side of the driven gear. A drive plate is slidably sleeved on the outer side of the drive column. The drive plate is fixedly connected to one end of the two middle sliding rods. An elongated hole is opened on the front side of the drive plate. The drive column is slidably sleeved in the elongated hole. A baffle is fixedly connected to the top of the sliding rod. A feeding port is opened at the bottom of the baffle. The baffle cooperates with the feeding port. The other end of the four sliding rods is fixedly connected to the same vertical plate. Two springs are fixedly connected to the other side of the chassis. One end of each spring is fixedly connected to one side of the vertical plate.

[0007] By adopting the above technical solution, grain is poured into the feeding hopper, and a hot air blower dries the grain inside the machine. The drive motor drives the rotation of the drive gear, which in turn drives the rotation of the driven gear and the drive column. The drive column slides up and down in the elongated hole, driving the drive plate, four moving rods, and the vertical plate to reciprocate left and right. The four moving rods drive the four baffles to reciprocate left and right, blocking the feeding port. This allows for intermittent control of the grain feeding flow, ensuring that the grain is quantitatively fed between the baffles for layered drying. This increases the contact area between the grain and the hot air, prolongs the contact time, and avoids the situation where some grain is not dried, greatly improving the drying effect and efficiency of the grain.

[0008] A further feature of this invention is that four sliding holes are provided on both sides of the chassis, and four moving rods are respectively slidably sleeved in two corresponding sliding holes.

[0009] By adopting the above technical solution, it is beneficial to guide the moving rod, making its movement more stable and smooth.

[0010] A further feature of this invention is that the stirring mechanism includes a servo motor fixedly connected to the front side of the chassis and four rotating cylinders rotatably connected to the inner walls of the front and rear sides of the chassis. A rotating shaft is fixedly connected to the output shaft of the servo motor. Four driving bevel gears are fixedly sleeved on the outer side of the rotating shaft. A driven bevel gear is fixedly connected to the front end of each of the four rotating cylinders. The four driving bevel gears mesh with the corresponding driven bevel gears. A number of stirring blades are fixedly connected to the outer side of the rotating cylinders.

[0011] By adopting the above technical solution, during the drying process, the servo motor drives the rotation of the rotating shaft and four active bevel gears, which in turn drive the rotation of four driven bevel gears. The four driven bevel gears then drive the rotation of four rotating drums and multiple stirring plates, thereby stirring the grain above the partition. This results in more even and comprehensive heating of the grain, further improving the drying effect and efficiency.

[0012] A further feature of this invention is that a stabilizing plate is fixedly connected to the front side of the chassis, and the top end of the rotating shaft is rotatably connected to the bottom of the stabilizing plate.

[0013] By adopting the above technical solution, it is convenient to support the rotating shaft, making its rotation more stable and smooth.

[0014] A further feature of this invention is that a guide plate is fixedly connected to the bottom inner wall of the casing, the guide plate is located below the air outlet of the hot air blower, a discharge port is fixedly connected to the bottom of one side of the casing, and an exhaust pipe is fixedly connected to the top of one side of the casing.

[0015] By adopting the above technical solution, it is convenient to discharge the dried grain and at the same time facilitate the removal of water vapor.

[0016] The beneficial effects of this utility model are:

[0017] 1. This utility model involves pouring grain into the feeding hopper, using a hot air blower to dry the grain inside the machine. The drive motor drives the rotation of the active gear, which in turn drives the rotation of the driven gear and the drive column. The drive column slides up and down in the elongated hole, causing the drive plate, four moving rods, and the vertical plate to reciprocate left and right. The four moving rods drive the four baffles to reciprocate left and right, blocking the feeding port.

[0018] 2. This utility model can intermittently control the flow rate of grain feeding and unloading, so that the grain is fed quantitatively between the partitions and dried in layers, which increases the contact area between the grain and the hot air, prolongs the contact time, avoids the situation that the grain is not dried in some areas, and greatly improves the drying effect and efficiency of the grain.

[0019] 3. This utility model uses a servo motor to drive the rotation of the rotating shaft and four active bevel gears. The four active bevel gears drive the rotation of four driven bevel gears, which in turn drive the rotation of four rotating drums and multiple stirring blades. This allows the grain above the partition to be stirred and agitated, resulting in more even and comprehensive heating of the grain and further improving the drying effect and efficiency.

The quantitative feeding mechanism 5 includes four sliding rods 504 that slide through both sides of the housing 1, and a support plate 501 fixedly connected to one side of the housing 1. A drive motor 502 is fixedly connected to the rear side of the support plate 501. A drive gear 503 and a driven gear 506 are rotatably connected from left to right on the front side of the support plate 501. The output shaft of the drive motor 502 is fixedly connected to the rear side of the drive gear 503. The drive gear 503 and the driven gear 506 mesh with each other. A drive column 507 is fixedly connected to the front side of the driven gear 506. A drive plate 505 is slidably sleeved on the outer side of the drive column 507. The drive plate 505 is fixedly connected to one end of the two moving rods 504 in the middle.

[0028] Specifically, a baffle 508 is fixedly connected to the top of the moving rod 504, and a discharge port 509 is opened at the bottom of the partition 7. The baffle 508 cooperates with the discharge port 509. The other end of the four moving rods 504 is fixedly connected to the same vertical plate 511. A long hole 512 is opened on the front side of the drive plate 505. The drive column 507 is slidably sleeved in the long hole 512. Two springs 510 are fixedly connected to the other side of the machine box 1. One end of each spring 510 is fixedly connected to one side of the vertical plate 511. Four sliding holes are opened on both sides of the machine box 1. The four moving rods 504 are slidably sleeved in the corresponding two sliding holes.

[0029] Specifically, the stirring mechanism 6 includes a servo motor 61 fixedly connected to the front side of the housing 1 and four rotating drums 66 rotatably connected to the inner walls of the front and rear sides of the housing 1. A rotating shaft 63 is fixedly connected to the output shaft of the servo motor 61. Four driving bevel gears 62 are fixedly sleeved on the outer side of the rotating shaft 63. A driven bevel gear 64 is fixedly connected to the front end of each of the four rotating drums 66. The four driving bevel gears 62 mesh with the corresponding driven bevel gears 64.

This allows for intermittent control of the grain flow rate, ensuring that the grain is quantitatively discharged between the partitions 7 for layered drying, increasing efficiency. The increased contact area between the grain and the hot air extends the contact time, preventing incomplete drying of certain grain areas and significantly improving the drying effect and efficiency.

Simultaneously, during the drying process, the servo motor 61 drives the rotation of the rotating shaft 63 and four active bevel gears 62, which in turn drive the rotation of four driven bevel gears 64. The four driven bevel gears 64 then drive the rotation of four rotating drums 66 and multiple stirring blades 67, thereby agitating and stirring the grain above the partition plate 7, resulting in more even and comprehensive heating of the grain and further improving the drying effect and efficiency.
