Description

Technical Field

[0001] This utility model relates to the field of seed screening technology, specifically a wheat seed screening device. Background Technology

[0002] Seed screening is the process of removing impurities from seeds using a filtration device. Inevitably, other impurities exist in seeds, and impurities larger than the sieve aperture can be filtered out by using sieves with different aperture sizes.

[0003] There are many types of screening devices available. According to the screening principle, they can be divided into: vibration screening, linear reciprocating screening, rotary screening, etc. Among them, linear reciprocating screening has a simple structure and low cost, and can achieve a certain screening effect. However, this type of screening device usually cannot control the amount of material entering. When too many seeds to be screened are introduced at one time, they will accumulate at one end of the screen, and the screening efficiency cannot be guaranteed. Furthermore, due to weather and seed accumulation, excess moisture will be generated inside the seeds, causing them to mold and deteriorate, affecting the germination rate.

[0004] Therefore, those skilled in the art have provided a wheat seed screening device to solve the problems mentioned in the background art. Utility Model Content

The adjustment mechanism includes two connecting rods 1, each fixedly installed on one end of the rotating shaft. The other ends of the two connecting rods 1 are respectively hinged to connecting rods 2. The bottoms of the two connecting rods 2 are hinged to each other. A telescopic rod is fixedly installed on the side wall of the housing. The telescopic part of the telescopic rod is connected to the bottom of the connecting rod 2. A drying device is provided on the housing.

[0007] Preferably, the drying device includes a warm air blower, an air intake assembly fixedly installed on the top of the casing, and an exhaust assembly fixedly installed on one side wall of the casing.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, the feed rate can be adjusted by setting a flap and an adjustment mechanism to control the opening and closing angle of the flap, thereby controlling the screening efficiency. When there are a lot of wheat seeds to be screened, the opening size of the flap can be appropriately reduced to avoid the accumulation of materials on the screen.

[0015] 2. In this utility model, by setting up a drying device, including a warm air blower and a suction fan, the warm air blown out by the warm air blower and the suction fan form an airflow inside the machine casing, which can dry the residual moisture of wheat seeds while transporting the moisture in the air to the outside, preventing the wheat seeds from becoming moldy due to excessive humidity and thus affecting the germination rate. At the same time, the filter element set inside the storage box can collect the dust and ash generated during the screening process inside the machine casing, making the screened wheat seeds cleaner.
