Mechanical clutch device

Abstract

The invention provides a mechanical clutch device. The mechanical clutch device comprises a rotating shaft, a support, a track plate, a control handle, a shifting fork, a circular ring, a tooth embedding sliding sleeve, a tooth embedding cover, a chain wheel, a bearing pressing plate, a bearing A and a bearing B; the clutch device is applied to a whole machine system, the support, the track plate,the rotating shaft and the chain wheel are mounted on other parts of the whole machine system, and the rotating shaft and the chain wheel are in transmission connection with the whole machine system;when the control handle is manually pulled to move along an axial groove of the track plate, the shifting fork, the circular ring and the tooth embedding sliding sleeve are driven to axially move onthe rotating shaft, the tooth embedding sliding sleeve and the tooth embedding cover are connected in an embedded manner or separated, and power transmission between the chain wheel and the rotating shaft is executed or cut off; when the control handle is pulled to be in a vertical groove at two ends, embedding teeth are completely engaged or separated, and the clutch device is kept in a separation state or a reunion state; and when the control handle rod is pulled to move along the vertical groove to the tail end, the state of the embedding teeth is unchanged, the position of the handle rod is fixed, and the clutch device is reliably separated and engaged, until the state is changed by the next manual operation.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery transmission, in particular to the design and application of a toothed clutch device on an agricultural work tool. Background technique [0002] Agricultural work tools are common agricultural machinery. Common agricultural work machines include seeders, fertilizers, or compound work machines combined with other functions, including multiple sets of work parts that are the same or similar between rows of one function, and a variety of Different types of working parts with different functions; different agronomic requirements in different places have special requirements for agricultural machinery, and there are often choices between the functions of the working tools, between rows and rows, between agricultural machinery and power sources, that is, whether each part works The problem; the machine system usually uses a clutch device to determine the transmission or cut-off of the pow...

Problems solved by technology

[0004] In order for the clutch device to have a fixed position function, in the prior art, one is to use a spring to press the steel ball, and the steel ball is against the socket hole attached to the control handle. To change the position, the handle needs to be pulled hard to overcome the spring. pressure and steel ball friction to ensure that the original position is not easy to change; the other is to use the length of the rotating thread or the movement of the handle with a cable in the limit groove, control the length and position of the compression spring of the clutch device, etc. to fix the separation or The position and state of the joint; these methods and structures have disadvantages such as complex structure, large space size, and high manufacturing cost
