Abstract
Description
Technical Field
[0001] The invention relates to the technical field of agricultural machinery, and in particular to an alternating drive mechanism of a double baler. Background Art
[0002] With the continuous development of agricultural and animal husbandry production technology in my country, the use of balers has gradually become popular. At present, the commonly used balers are mainly single-baler balers, which have only one baling channel and can only bale one bundle of straw at a time, with low efficiency. In order to improve the efficiency of baling, the patent document with publication number CN222284028U provides a technical solution of "double-outlet knotter type square baler". The solution adopts a double baling channel, which can baling two bundles of straw at the same time, doubling the baling efficiency. However, the baler of this solution uses two gearboxes to drive two pistons to act synchronously, completing two baling actions at the same time. This synchronous drive structure is not only complex in structure and high in cost, but also consumes a lot of power during operation due to the synchronous work of the two pistons, and the vibrations are superimposed at the same time, which has a great impact on the equipment, resulting in unstable operation of the equipment, amplified noise, and poor driving experience. Under long-term continuous vibration impact, the equipment ages and wears out faster, and the service life of related parts is affected, which greatly increases the use and maintenance cost of the equipment. Summary of the invention
[0003] The technical problem to be solved by the present invention is to provide a driving mechanism of a double baler which is more stable and adopts alternating drive.
[0004] The technical solution of the present invention is: an alternating drive mechanism of a double baler, comprising a gearbox, a piston and a feed fork, wherein an output end is provided on each side of the gearbox, the two output ends are coaxially arranged and respectively connected to a crankshaft, the cranks of the two crankshafts are arranged with a phase difference of 180 degrees, the pistons are respectively connected to the cranks of one crankshaft through connecting rods, the output end of the gearbox is connected to the input shaft of the feed fork through a transmission device, and the feed fork is driven to cooperate with the pistons in the same group.
[0005] The technical effect of the present invention is that it has the advantages of reasonable design, simple structure, low energy consumption and smoother operation. The alternating drive mechanism is used to drive the two pistons to act alternately, so that the working moments of the two pistons are staggered, which not only reduces vibration impact and makes the equipment run more smoothly, but also reduces the driving power and reduces the energy consumption of the equipment.
