Embodiment 1

[0035] see Figure 1 to Figure 5 As shown, Embodiment 1 of the present invention provides a pulley, including a fixed plate 101 and a moving plate 102; and the second working surface 104 respectively facing the opposite direction; the first working surface 103 of the moving disk can form a belt groove 105 with the working surface of the fixed disk; the turning disk can make the second working surface 104 of the moving disk and the fixed disk A belt groove 105 is formed between the working faces.

[0036] Specifically, during use, the first working surface 103 of the moving disk can be made to face the working surface of the fixed disk to form the belt groove 105 for accommodating the V-belt, or the second working surface 104 can be aligned with the fixed disk by turning over the rotating disk. The working surfaces of the discs are opposite to form a belt groove 105 for accommodating the V-belt 118. The belt groove 105 is tapered, that is to say, the groove width of the belt g...

Embodiment 2

[0054] The pulley in this embodiment is an improvement on the basis of Embodiment 1. The technical content disclosed in Embodiment 1 will not be described repeatedly, and the content disclosed in Embodiment 1 also belongs to the content disclosed in this embodiment.

[0055] see Figure 6 As shown, in this embodiment, a second accommodating groove 116 is opened on the working surface of the fixed disk, which is used to accommodate the setting part of the first working surface 103 of the moving disk and / or accommodate the second working surface 104 of the moving disk. The setting part is used to adjust the width of the belt groove 105 formed between the fixed plate and the movable plate. By opening the second accommodating groove 116 on the working surface of the fixed disk, the adjustable width of the belt groove 105 can be increased, thereby helping to make the pulley have a larger speed regulation range, that is, to meet different harvesting conditions. The speed regulation...

Embodiment 3

[0057] This embodiment also provides a pulley. The pulley of this embodiment describes another implementation in which the width of the belt groove formed between the fixed plate and the moving plate can be adjusted. Other implementations The technical solution of Example 1 also belongs to this embodiment and will not be described again.

[0058] In this embodiment, a second accommodating groove is opened on the working surface of the fixed disk, which is used to accommodate the setting part of the first working surface of the moving disk and / or the setting part of the second working surface of the moving disk, so as to adjust The width of the belt groove formed between the fixed plate and the moving plate. It should be noted that, in this embodiment, neither of the two working surfaces of the moving disk may have the first receiving groove.

[0059] In summary, the pulley provided by this embodiment can increase the adjustable speed range of the pulley, meet the speed regula...

Abstract

The invention relates to the technical field of agricultural machinery, in particular to a belt pulley, a crop raking mechanism and a harvester. The belt pulley comprises a fixed disc and a movable disc, wherein the movable disc comprises a first working surface and a second working surface which are oppositely arranged, a belt groove can be formed between the first working surface of the movabledisc and the working surface of the fixed disc, and the belt groove can be formed between the second working surface of the movable disc and the working surface of the fixed disc by turning the movable disc. The crop raking mechanism comprises the belt pulley. The harvester comprises the crop raking mechanism. According to the belt pulley, the crop raking mechanism and the harvester, the practicability is relatively high, the speed regulation range can be increased.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a pulley, a reeling mechanism and a harvester. Background technique [0002] At present, in order to meet the normal harvesting under different crop conditions such as upright, partially lodging and completely lodging, the existing crawler-type rice machines need to adjust the speed of the reel. The speed of the reel is mostly adjusted by the speed change device. The existing speed regulating devices are all realized by the combination of single-stage or two-stage pulleys with different diameters. Diameter, the working diameter of the V-belt in the speed regulating device can be adjusted to realize the adjustment of the speed of the pulley, and then adjust the speed of the reel, but this speed regulating device has poor practicability and a small adjustable speed range. shortcoming. Contents of the invention [0003] The object of the present invention is to pr...
