The invention discloses a grain unloading oil cylinder provided with a throttling gear. The grain unloading oil cylinder comprises a cylinder barrel, a cylinder bottom and a piston rod, and is characterized in that the cylinder barrel is hollow inside, the cylinder bottom is arranged at the left end of the cylinder barrel, a piston arranged in the cylinder barrel is arranged on the inner side of the cylinder bottom, a fixed locking nut is arranged at the left end of the piston, an oil port I is arranged above the piston and located in the outer wall of the cylinder barrel, throttling pieces are arranged in the oil port I, a guide sleeve is arranged at the right end in the cylinder barrel 1, an oil port II is arranged above the guide sleeve and located in the outer wall of the cylinder barrel, and the piston rod sequentially penetrates through the guide sleeve and the piston from right to left and is fixed on the piston through the locking nut. The throttling pieces are added in the oil ports, so that the throttling function is realized, and stable turning of a grain bin is guaranteed. The oil cylinder is convenient to assemble, the production efficiency is improved, and the service life is prolonged.
Description
technical field [0001] The invention relates to an oil cylinder, in particular to a grain unloading oil cylinder with a throttling device. Background technique [0002] Agricultural harvesting machinery and equipment unloading grain and oil cylinders are too fast and unstable when lifting and falling back to the granary, which will cause certain damage to the use of granaries and hydraulic cylinders, affect the stability and efficiency of harvesting machinery, and have a short service life. Contents of the invention [0003] The object of the present invention is to provide a grain unloading oil cylinder with a throttling device that can ensure stable turning of the granary, fast unloading and long service life. [0004] In order to achieve the above object, the present invention includes a cylinder, a cylinder bottom and a piston rod. The inside of the cylinder is hollow, and the left end of the cylinder is provided with a cylinder bottom. The inside of the cylind...
