Discrete variable speed and human hybrid driving multi-freedom-degree controllable mechanism type sugarcane loading machine

Abstract

The invention provides a discrete variable speed input multi-freedom-degree controllable mechanism type sugarcane loading machine which comprises a combustion motor, a transmission device and a multi-freedom-degree connecting rod mechanism. The transmission device comprises a transfer case, a clutch and a speed reducer. The multi-freedom-degree connecting rod mechanism comprises a movable arm lifting branched chain, a lower fork overturning branched chain and an upper fork overturning branched chain. Driving rods are driven by one combustion motor, starting and stopping of all the driving rods and switching of positive driving and negative driving can be achieved under the control of the clutch and a reversing device of the transmission device, the branched chains are matched mutually to move, an upper fork and a lower fork achieve complicated and variable movement, loading and unloading of goods of sugarcane and the like are completed, and the sugarcane loading machine overcomes the defect that hydraulic elements of a hydraulic loading machine are high in manufacturing cost, complicated in maintenance and the like. The sugarcane loading machine is driven by the combustion motor, overcomes power limit cased by motor driving, achieves field construction conveniently, and improves practicability and convenience.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a sugarcane loader with multiple degrees of freedom and controllable mechanisms driven by a hybrid of discrete variable speed and human power. Background technique [0002] The sugarcane loader is a kind of construction machinery widely used in many occasions such as sugarcane loading, straw loading and unloading, wood handling, etc. It is convenient to grasp sugarcane, wood, steel pipe, and materials by replacing different grab buckets. . There are many types of sugarcane loaders. The most widely used hydraulic sugarcane loaders are highly efficient and can load and unload sugarcane in a short time, which greatly improves labor efficiency and reduces labor intensity. However, the existing sugarcane loaders The machine also has many disadvantages.

Problems solved by technology

There are many types of sugarcane loaders. The most widely used hydraulic sugarcane loaders are highly efficient and can load and unload sugarcane in a short time, which greatly improves labor efficiency and reduces labor intensity. However, the existing sugarcane loaders The machine also has many disadvantages. Due to the hydraulic system, the manufacturing precision of hydraulic parts is high, the cost of manufacturing and maintenance is high, and the hydraulic system is easily affected by environmental factors, especially in low temperature or high temperature environments, prone to weakness or vibration, etc. Happening

[0003] The multi-degree-of-freedom controllable mechanism can be used to replace the traditional hydraulic system and avoid many shortcomings of the hydraulic system. However, the multi-degree-of-freedom controllable mechanism is generally driven by a servo motor, and there is a limitation in power supply, so it is not easy to implement field construction
