Automatic grain metering device

Abstract

The invention discloses a grain automatic metering device, which comprises a casing and a rotor assembly inside the casing, the casing includes an arc floor and a curved angle steel covered on the arc bottom plate; the rotor assembly includes a fixed mandrel on which a The support plate and the center wheel that can rotate around the mandrel; the center wheel is uniformly provided with spokes in a radial shape, and the end of the spoke is provided with a cylinder on the side facing the support plate, and a scraper is connected to the side away from the support plate, and two adjacent scrapers There is an arc-shaped partition between them, and a rotating shaft parallel to the mandrel runs through the supporting plate. One end of the rotating shaft is provided with a gear, and the other end is provided with a connecting rod hinged to the sliding fork. The sliding fork is a rectangular plate structure and The plate surface is perpendicular to the rotating shaft. One end of the sliding fork is provided with a strip-shaped through chute set on the mandrel. Sporty U-shaped forks. The device can automatically and continuously weigh grain, and is easy to monitor failures.

Description

technical field [0001] The invention belongs to the technical field of agriculture, in particular to an automatic continuous weighing device for grain. Background technique [0002] my country is a country with a large population, a large food consumption country, and a large food production country. Whether it is an agricultural contracting self-employed or a large-scale industrialized farm, the grain harvest and storage are faced with frequent grain weighing, and in the daily settlement of various grain trade In the process, it is unavoidable to weigh all kinds of grains. At present, for grain weighing, individual contractors often use the original manual weighing method, which consumes a lot of energy and has extremely low weighing efficiency. Or other existing weighing devices with slightly higher efficiency use sensors for weighing, and sensors are electronic products. Due to the failure of the sensor or the structure related to it, the weighing error becomes larger, b...

Problems solved by technology

At present, for the weighing of grain, individual contractors often use the original manual weighing method, which consumes a lot of energy and the weighing efficiency is extremely low, and large-scale floor scales are not suitable for small farmers. Or other existing weighing devices with slightly higher efficiency use sensors for weighing, and sensors are electronic products. Due to the failure of the sensor or the structure related to it, the weighing error becomes larger, but the on-site staff cannot intuitively detect it.

Furthermore, weighing devices such as ground scales all need to move the grain to the scale and weigh intermittently, so the labor intensity is still relatively large and the efficiency is not high.
