This utility model discloses a buffer-type integrated hydraulic cylinder for high-horsepower tractors, comprising a cylinder body, a cylinder bottom and a rod head respectively disposed at both ends of the cylinder body, a piston movably mounted inside the cylinder body, and a piston rod fixedly mounted to the piston to push the rod head. An oil passage mounting block is integrally mounted on one side of the top of the cylinder body, and the oil passage mounting block has an A oil passage port and a B oil passage port respectively. Both the A and B oil passage ports have buffer mechanisms installed at their extensions into the cylinder body. A rod head end cap is fixedly mounted at one end inside the cylinder body, and a buffer ring is fixedly mounted inside the rod head end cap. During the oil return process, the oil pressure squeezes the oil ring, forcing the returning hydraulic oil to return only from inside the extension, thereby reducing the pressure generated by the oil return and achieving a certain buffering effect on the piston, increasing the buffering capacity of the cylinder.

The bore is reduced while the stroke is not lengthened to maintain the required displacement. [Solution] If we consider a square combustion chamber with a displacement of approximately 500cc, a bore and stroke of 54mm x 54mm x 4 pistons results in a very small bore and stroke of 494.6cc, compared to a normal single-piston engine with a bore and stroke of 85.72mm x 85.72mm and a displacement of 494.6cc. With an area ratio of 2.52 to 1 compared to a normal single-piston engine, the 4 pistons will experience more than 2.5 times the combustion pressure if the compression ratio is the same. If a normal single-piston 3-cylinder 1484cc engine produces 100 horsepower, then a 4-piston engine would theoretically produce 250 horsepower. And all this with the fuel efficiency of a naturally aspirated 1.5L engine. Although there are considerable mechanical losses due to the movement of four pistons and two crankshafts, the resulting increase in power more than compensates for these losses.

A continuously variable steering single-furrow plowshare is disclosed. The plowshare is a four-bar linkage mechanism including front and rear connecting plates, and consists of two parallel rods with a fixed length of 690±10mm. When the plowshare is connected to the tractor, a length that is too long will cause the tractor to veer off course; a length that is too short will result in insufficient row spacing. This invention changes the traditional structure of plowshares, which have relied on naturally occurring wood profiles or modern metal plowshares mimicking the length of wooden plowshares. The fixed-length plowshare, when installed on any horsepower tractor, will not cause ridge deviation or crossing of rows. The rear plow frame of this continuously variable steering single-furrow plowshare contains a counterweight made of sand and gravel within its square steel cavity. This counterweight solves the problem of the plowshare being front-heavy and rear-light, causing the plowshare to gradually lift up during tilling and resulting in shallower tillage. The plowshare structure of this continuously variable steering single-furrow plowshare is rationally designed. Using a single-furrow plow with this plowshare has significant social and economic benefits.
