Abstract

The invention discloses a multifunctional agricultural hay collecting device. The multifunctional agricultural hay collecting device is provided with a hydraulic cylinder and universal joints. The hydraulic cylinder comprises a cylinder body and a heat insulation sleeve, the cylinder body is sleeved with the heat insulation sleeve, a cavity is arranged between hay collecting units, the heat insulation sleeve is wrapped by a heat insulation band, and the cavity is with a compressed air inlet and outlet. Each universal joint comprises an end connecting joint, a middle joint and a connecting assembly. According to the multifunctional agricultural hay collecting device, the heat insulation sleeve is additionally arranged on the surface of the hydraulic cylinder, the heat-resistant band is wound around the outer surface of the heat insulation sleeve, then an air cavity layer is formed between the hydraulic cylinder and the heat insulation sleeve, compressed air flows in the air cavity layer to take away heat, and therefore the whole hydraulic cylinder is sufficiently cooled; the universal joints have high strength and can bear large torque, and therefore the perforating requirement is met; different connectors are arranged and used for being connected with different workpieces, and therefore the application range is wide, and connection is fast; the service life is long, the replacement rate of the universal joints in working is decreased, and working efficiency is improved; besides, the multifunctional agricultural hay collecting device is convenient to operate, good in safety performance and high in practicality and economy.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a multifunctional agricultural hay collector. Background technique [0002] A hay collector is attached to the rear of an agricultural machine (eg, a tractor) to receive power from the agricultural machine. This hay collector is used to collect and wrap hay after the grass has been cut and dried to remove moisture therefrom to form hay stacks of a predetermined volume so that the hay can ferment and at the same time prevent foreign matter from being destroyed during the storage of the grass. Introduced into this hay so that the hay can be used as feed for livestock. The cooling effect of the hydraulic cylinder of the existing agricultural hay collector is poor, the replacement frequency of the universal joint is high, the work efficiency is low, and the service life is short. Contents of the invention [0003] The purpose of the present invention is to provide ...
