Soil removing device for belt pulley of agricultural machine

Abstract

The invention discloses a soil removing device for a belt pulley of an agricultural machine. According to the soil removing device disclosed by the invention, the soil removing device is mounted on the existing belt grooved pulley and is driven by using power of the belt grooved pulley, scraped mud soil is pushed to one side of a belt in a manner that a tilted scraping blade is matched with blowing of fan blades, and thus, secondary attachment is avoided. The soil removing device is characterized in that a primary fixing frame and an auxiliary fixing frame are connected through an impeller shaft, a supporting bearing is arranged at a joint between the primary fixing frame and the auxiliary fixing frame, the primary fixing frame and the auxiliary fixing frame are in parallel, a scraping impeller sleeves the impeller shaft and is located between the primary fixing frame and the auxiliary fixing frame, a plurality of scraping blade plates are arranged on the impeller shaft in an equiangular manner, are trapezoidal plates and are of oblique stretching distribution, a connecting lug is arranged at the bottom of the primary fixing frame, one end of a fan shaft is arranged on the connecting lug at the bottom of the primary fixing frame through a bearing, and the fan blades are arranged at the other end of the fan shaft.

Description

technical field [0001] The invention relates to a soil removing device for a pulley of an agricultural machine, relating to a device for removing soil from a belt grooved pulley of an agricultural machine, which belongs to the field of agricultural equipment. In particular, it relates to a device that is installed on the existing belt sheave, driven by the power of the belt sheave, and pushes the scraped soil to the side of the belt through the inclined scraping blades and the blowing of the fan blades, so as to avoid the formation of secondary adhesion. Soil device. Background technique [0002] Due to the influence of the working environment of agricultural machinery, the belt as the transmission mechanism is easy to adhere to the soil.

AI Technical Summary

Problems solved by technology

[0002] Due to the influence of the working environment of agricultural machinery, the belt as the transmission mechanism is easy to adhere to the soil. The soil adhered to the belt will be squeezed and accumulated in the groove of the belt sheave with the transmission of the belt. The accumulation of soil for a long time will cause Cause poor contact between the belt and the belt sheave, resulting in belt slippage or even belt shedding. At present, in the prior art, a scraper is added to the belt sheave to remove the soil in the groove of the sheave, but when removing the soil , because the scraper is located directly above the lower belt, and the soil dropped by the scraper will fall on the lower belt again, which will easily cause secondary contact and adhesion between the mud and the belt sheave

[0003] Notification number CN207124879U discloses a soil removal device for belt sheaves of agricultural machinery, including sheaves, axles, support plates and scrapers, at the bottom of the agricultural machinery, and a wheel axle is fixedly arranged on one side of the belt, sleeved on the axle A sheave is provided, the said sheave is closely attached to the belt, a support plate is provided on the wheel shaft below the sheave, a through hole is provided at one end of the support plate, and one end of the support plate is sleeved on the wheel shaft through the through hole It is characterized in that a scraper is provided on the other end of the support plate, and one end of the scraper is extended to the sheave with a soil removal part, and the soil removal part matches the groove of the sheave, and the scraper The other end of the plate is provided with a tension spring connected with the frame of the agricultural machinery. When the device removes the soil, the soil scraped off will easily fall back onto the belt facing below, causing secondary friction between the soil and the belt sheave. Contact, affecting soil removal effect

[0004] The notification number CN108541407A discloses an adjustable agricultural machinery belt sheave soil removal device, including: a bearing disc, a chandelier body and a surrounding ring; several fan blade mechanisms located outside the chandelier body, and driving several The interlocking mechanism of the fan blade mechanism doing circular motion; the chandelier body is fixedly installed at the center of the lower end of the bearing disc, and the center of the upper end of the bearing disc is fixedly connected with the top surface of the wall through a fixed rod, and the surrounding ring The inner side is fixedly connected with the outer side of the bearing disc; when the device is scraping soil, the fallen soil cannot be effectively pushed away from the lower belt, so that the soil falls on the belt again, causing secondary adhesion of the soil to the belt sheave. attached
