Problems solved by technology

[0002] The transmission mechanisms of various harvesters working in the field mostly use transmission sheaves and transmission belts. During work, the notches of the transmission sheaves are easy to enter the soil, resulting in frequent belt drop and affecting normal production.
In order to solve this problem, a mud scraper is assembled on the side of the transmission sheave, and the mud scraper extends into the notch to scrape off the soil in the notch. The disadvantage is that the structure and process are complicated, and the use effect is not very ideal. It is easily damaged and requires frequent maintenance, which affects normal production

Embodiment Construction

[0014] See figure 1 , 2 , The structure of Embodiment 1 of the present invention is as follows: the main body of the sheave is provided with two wheel pieces 2 with a central hole, and the connecting ribs 3 of 3-4 steel bars are welded evenly along the circumferential direction between the two wheel pieces 2 . Leakage holes 1 are formed between the connecting ribs 3, and the two wheel pieces 2 and the evenly distributed connecting ribs 3 form notches. The earth or sundries that enter the notch of the drive sheave during operation leak out from the leakage hole 1 to prevent the belt from falling off. One side of the main body of the sheave is connected with the bearing sleeve 4 . The production can also be done by casting process.

Abstract

The invention relates to a novel belt pulley comprising a groove pulley main body with a notch. The novel belt pulley is characterized in that the groove pulley main body is provided with two pulley pieces which are connected by a connection part with a leakage hole and form the notch with a connection part. The utility model has the advantages that the notch of the groove pulley can internally leak earth and sundries, the falling-off of the pulley is prevented, the structure and the technology are simplified, the cost is low, and the maintenance is avoided.

Description

technical field [0001] The invention belongs to an agricultural machinery transmission part, in particular to a new pulley. Background technique [0002] Most of the various harvesters working in the field use transmission sheaves and transmission belts for their transmission mechanisms. During work, the notches of the transmission sheaves are easy to enter the soil, resulting in frequent belt drop and affecting normal production. In order to solve this problem, a mud scraper is assembled on the side of the transmission sheave, and the mud scraper extends into the notch to scrape off the soil in the notch. The disadvantage is that the structure and process are complicated, and the use effect is not very ideal. It is easily damaged and requires frequent maintenance, which affects normal production. Contents of the invention [0003] The purpose of the present invention is to provide a new type of belt pulley, which can leak soil and sundries in the notch, prevent the belt ...
