Earth furrowing arm of tractor

Abstract

The invention belongs to the technical field of farm equipment, and relates to an earth furrowing arm of a tractor, which solves the problem that an earth furrowing device on a tractor cannot be replaced. The invention provides an earth furrowing arm of the tractor. The earth furrowing arm comprises an earth furrowing arm body and an earth furrowing cutter which is arranged on one end of the earth furrowing arm body, wherein a connecting port which is connected with a traction port of a speed changing box of the tractor is arranged at a position, corresponding to the other end of the earth furrowing cutter, of the earth furrowing arm body of the tractor, a transitional gear set is arranged in the earth furrowing arm body; the transitional gear set comprises an acting gear, a driving gear and a transmission gear set, wherein one end of the acting gear is connected with the earth furrowing cutter through a shaft, the other end of the driving gear is engaged with an external gear of the speed changing box of the tractor when the connecting port is connected with the traction port of the speed changing box of the tractor, and two ends of the transmission gear set are respectively engaged with the acting gear and the driving gear. By adopting the technical scheme, the technical problems can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery and relates to a tractor ridge opening arm. Background technique [0002] The types of walking tractors commonly used in China are GT121 and GT111, and the ridge opener is an application of these two walking tractors in the agricultural field. The common ridge opener is equipped with a ridge opener at its bottom. [0003] With the development of planting technology in the direction of refinement, for different crops or different farmlands, it may be necessary to choose different ridge-opening equipment, but since the ridge-opening equipment and tractor are usually in an integrated structure, when it is necessary to perform ridge-opening operations, farmers It is often necessary to buy a tractor with a ridge opening device. For farmers who have already purchased a tractor, this has caused a certain amount of excessive consumption, which has increased the cost of agricultural product...

Problems solved by technology

[0003] With the development of planting technology in the direction of refinement, for different crops or different farmlands, it may be necessary to choose different ridge-opening equipment, but since the ridge-opening equipment and tractor are usually in an integrated structure, when it is necessary to perform ridge-opening operations, farmers It is often necessary to buy a tractor with ridge opening equipment. For farmers who have already purchased tractors, this has caused a certain amount of excessive consumption, which has increased agricultural production costs and the economic burden of farmers.
