Description

Technical Field

[0001] The utility model relates to the technical field of seed detection, in particular to a seed moisture detection device. Background Art

[0002] Seed moisture is an important factor affecting the lifespan and safe storage of seeds, and is also one of the main indicators for seed grading. 1. Mildew: During storage, if the seed moisture is too high, the respiration is vigorous, generating a large amount of respiratory heat and moisture, which will cause the seed pile to heat up and mildew; 2. Phytotoxicity: Seeds with high moisture have vigorous respiration, and when fumigating the warehouse with chemicals, they inhale too much chemical dosage and cause phytotoxicity, thus reducing viability; 3. Freezing injury: Seeds with high moisture are prone to freezing injury and reduce the germination rate.

[0003] A seed moisture detection device proposed in the publication number: CN 220270969 U. In this case, a worm drives a worm wheel to rotate, driving a rotating shaft and a feeding bin to rotate. The seeds are continuously lifted by the feeding blades as the feeding bin rotates, and are heated by a microwave heater. After the moisture is continuously heated and evaporated, the seeds are quickly dried. The overall structure of the seeds will not be damaged during the drying process, and the problem of seed debris residue can be avoided, improving the measurement accuracy. However, in actual use of the above case, the seeds will adhere to the inner wall of the feeding bin after drying, resulting in inconvenient seed feeding and very troublesome use. Therefore, it is necessary to propose a seed moisture detection device to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a seed moisture detection device with the effect of convenient feeding.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: A seed moisture detection device includes a bottom plate and two side plates symmetrically arranged on the upper end of the bottom plate. A seed drying bin is installed between the two side plates. A drying component is arranged above the drying bin, and a seed feeding component is arranged in the inner cavity. The seed feeding component includes push plates symmetrically arranged on the left and right in the inner cavity of the seed drying bin. A first motor is arranged above the seed drying bin, and a bidirectional lead screw is installed at the output end of the first motor. Two symmetrically arranged connecting blocks are threadedly arranged on the outer side of the bidirectional lead screw, and the connecting blocks are fixedly connected with the push plates.

[0006] By adopting the above technical solutions, after the seeds are dried, the first motor drives the bidirectional lead screw to rotate, so that the two connecting blocks drive the two push plates to approach each other in the seed drying bin, thereby pushing the seeds out of the drying bin, which can prevent the seeds from adhering to the inner wall and make the feeding more convenient.

[0007] A further setting of the present utility model is that a limiting groove for the left - right sliding of the connecting block is provided at the upper end of the seed drying bin, and a limiting rod slidably connected to the two connecting blocks is horizontally provided at the bottom of the bidirectional lead screw.

[0008] By adopting the above - mentioned technical solution, the setting of the limiting groove and the limiting rod makes the horizontal sliding of the connecting block more stable, thereby stably driving the push plate to slide left and right.

[0009] A further setting of the present utility model is that fixing blocks connecting the bidirectional lead screw and the limiting rod are installed on both the left and right sides at the top of the seed drying bin.

[0010] By adopting the above - mentioned technical solution, the bidirectional lead screw and the limiting rod are reasonably arranged at the upper end of the seed drying bin.

[0011] A further setting of the present utility model is that the push plate fits the inner wall of the seed drying bin, and a blanking pipe is provided at the bottom of the seed drying bin.

[0012] By adopting the above - mentioned technical solution, the push plate can push the seeds on the inner wall of the seed drying bin out and discharge them through the blanking pipe.

[0013] A further setting of the present utility model is that the drying assembly includes a wind frame installed at the top between the two side plates. A heater and three fans located above the heater are arranged in the wind frame, and a driving member for controlling the rotation of the fans is provided at the upper end of the wind frame.

[0014] By adopting the above - mentioned technical solution, the three fans are controlled by the driving member to rotate, and the generated air flow is heated by the heater to form hot air, which can more quickly dry the seeds in the seed drying bin.

[0015] A further setting of the present utility model is that the driving member includes a second motor installed on one side plate. A worm is installed at the output end of the second motor, and a worm gear adapted to the worm is installed at the upper end of the fan.

[0016] By adopting the above - mentioned technical solution, the second motor controls the rotation of the worm, and through meshing, the three worm gears are pushed to rotate, thereby driving the three fans to rotate and generating an air flow to dry the seeds.

[0017] A further setting of the present utility model is that rotating shafts rotatably connected to the side plates are installed at both the left and right ends of the seed drying bin. Synchronous wheels are installed at the ends of the rotating shaft on the left side and the worm. A synchronous belt is provided between the two synchronous wheels.

[0018] By adopting the above - mentioned technical solution, while the worm rotates, the synchronous belt drives the two synchronous wheels to rotate, causing the rotating shaft to rotate, thereby driving the whole seed drying bin to rotate, continuously flipping the seeds, and accelerating the drying efficiency of the seeds.

[0019] A further setting of the present utility model is that a fixing plate is installed on the side plate on the right side, and a humidity sensing device is installed on the fixing plate.

[0020] By adopting the above technical solution, the humidity sensing device senses the humidity when the seeds are dried. When the humidity reaches the standard, the seed drying is completed, which is convenient for storage.

[0021] A further setting of the present utility model is that a storage box and a shaking component for driving the storage box to shake left and right are further arranged above the bottom plate.

[0022] By adopting the above technical solution, after the seeds are fed into the storage box, they are shaken evenly by the shaking component, which is convenient for direct storage.

[0023] A further setting of the present utility model is that the shaking component includes two guide rods installed between the two side plates. Guide blocks slidably connected to the guide rods are installed on the front and rear side walls of the storage box. An electric telescopic rod connecting the bottom of the storage box is installed on the left side plate.

[0024] By adopting the above technical solution, the electric telescopic rod is driven. Under the guidance of the guide rods and the guide blocks, the electric telescopic rod expands and contracts to push the storage box to slide back and forth, thereby shaking the storage box back and forth to shake the seeds inside evenly.

[0025] The beneficial effects of the present utility model are:

[0026] 1. In the present utility model, the second motor controls the rotation of the worm. Through meshing, three worm wheels are driven to rotate, thereby driving three fans to rotate. The generated air flow is heated by the heater to form hot air, which dries the seeds in the seed drying bin more quickly. While the worm rotates, the synchronous belt drives two synchronous wheels to rotate, causing the rotating shaft to rotate, thereby driving the overall rotation of the seed drying bin to continuously flip the seeds and accelerate the seed drying efficiency.

[0027] 2. In the present utility model, the first motor drives the bidirectional lead screw to rotate. Under the limitation of the limit rod, two connecting blocks drive two push plates to approach each other inside the seed drying bin, thereby pushing the seeds out of the drying bin and discharging them into the storage box through the feeding pipe, which can prevent the seeds from adhering to its inner wall and make the feeding more convenient.
