Problems solved by technology

[0003] In the current combine harvester, in various transmission processes and transmission mechanisms, it is often necessary to use belts and pulleys that match the belts. The traditional pulleys are all equipped with V-shaped grooves to match the belt, but this can only be used with the belt. A kind of belt matching, when it is necessary to change the speed, only the pulley can only be replaced, which is not only troublesome, but also can only achieve stepped speed change

Embodiment 1

[0022] Embodiment 1, see attached figure 1 The fan pulley structure for the harvester includes a transmission shaft 1, an intermediate wheel 2 fixed on the transmission shaft 1, a left side wheel 3 that is installed on the intermediate wheel 2 and can move axially, and is installed On the middle wheel 2 and the right side wheel 4 capable of axial movement, the axial through hole 5 arranged on the transmission shaft 1, the connecting mechanism 6 arranged in the axial through hole 5 and the The adjustment connecting mechanism 7 that described left side wheel 3, right side wheel 4 and middle wheel 2 are connected; Said middle wheel 2 is provided with left side plane and is positioned at described left side plane radial outside The left annulus 8 that intersects and inclines to the direction of the right wheel 4, the right plane, and the right annulus 9 that intersects the right plane radially outside the right plane and inclines to the direction of the left wheel 3, so The exten...

Embodiment 2

[0023] Embodiment 2, see attached figure 2 , 3 ; In this embodiment, the left wheel 3 and the right wheel 4 are sleeved on the transmission shaft 1, and can rotate and slide axially on the transmission shaft. The left wheel 3 and the transmission A locking mechanism 14 is provided between the shafts 1 and between the right side wheel 4 and the transmission shaft 1. When the left side wheel 3 and the right side wheel 4 move on the transmission shaft 1 at a speed exceeding Lock the left side wheel 3 and the right side wheel 4 at a predetermined value; the locking mechanism 14 includes and is arranged on the left side wheel 3 and the right side wheel 4. The axial groove 1402 on the transmission shaft 1, the roller 1403 hinged in the axial groove 1402, the teeth 1404 arranged on the roller 1403 and meshed with the rack 1401 and arranged on the shaft To the slot 1405 at the bottom of the groove 1402, the outer circumference of the roller 1403 is provided with an opening guide gr...

Abstract

The invention discloses a pulley structure for a harvester, which comprises a transmission shaft, an intermediate wheel fixed on the transmission shaft, a left side wheel which is installed on the intermediate wheel and can move axially, and is installed on the The right side wheel on the intermediate wheel and capable of moving axially, the axial through hole arranged on the transmission shaft, the connecting mechanism arranged in the axial through hole and the left side wheel, the right side wheel The adjustment connection mechanism that connects the side wheel and the middle wheel. The pulley structure used for the harvester of the present invention adjusts the distance between the left pulley, the right pulley and the middle pulley by adjusting the connection mechanism to achieve the purpose of matching with belts of different specifications. The adjustment is convenient and fast, and can realize stepless speed change.

Description

technical field [0001] The invention relates to the technical field of harvesters, and more specifically relates to a pulley structure for harvesters. Background technique [0002] Patent Publication No. CN102469764A, a Chinese invention patent with a publication date of 2012.5.23 discloses a combine harvester that can transmit power from the engine to the harvesting section via the harvesting drive input mechanism. It is characterized in that, on the side of the harvesting drive input mechanism The engine is configured on the other hand, in which there is an exhaust gas recirculation device for recirculating a part of the exhaust gas from its exhaust system to the intake system, in the space between the harvesting drive input mechanism and the engine A communication mechanism of the exhaust gas recirculation device that communicates the exhaust passage of the exhaust system with the intake passage of the intake system is provided. [0003] In the current combine harvester,...
