Abstract

The invention relates to an adjustment screw rod of a sowing machine, belonging to the technical field of agricultural machinery, and aiming at solving the problems that the existing adjustment screw rod of the sowing machine is inconvenient and inaccurate to adjust, and adjustment needs a high driving force. According to the adjustment screw rod of the sowing machine, an outer shaft sleeve comprises a shaft sleeve thread part, a shaft sleeve polish rod part, two installation locating rings and a milling flat part, wherein the shaft sleeve thread part, the shaft sleeve polish rod part and the milling flat part are manufactured into a whole on the same axis from left to right; the two installation locating rings are fixed on the shaft sleeve polish rod part in parallel in the horizontal direction; a support seat is arranged between the two installation locating rings; the right side of the screw rod is inserted into the outer shaft sleeve, and the right end of the screw rod penetrates outside the outer shaft sleeve; a ball bearing is connected with the part, penetrating outside the outer shaft sleeve, of the right end of the screw rod; two gaskets are respectively arranged on the two sides of the ball bearing; the ball bearing and the gaskets are locked on the end surface of the right side of the milling flat part by lock nuts which are arranged on the right sides of the ball bearing and the gaskets. The adjustment screw rod is used for the sowing machine.

Description

technical field [0001] The invention relates to an agricultural machinery adjusting screw, in particular to a planter adjusting screw, which belongs to the technical field of agricultural machinery. Background technique [0002] The seeder is the most widely used agricultural machinery in agricultural production. During the working process, it is necessary to adjust the amount of sowing and fertilization according to the type of seed to be sown, the spacing of sowing, and the conditions of sowing cultivated land. The existing adjustment device is only the hand wheel to drive the screw to rotate as a whole, which is inconvenient and inaccurate to adjust. The longer screw is prone to deformation such as convex or concave during long-term use, and the transmission force required for adjustment big downside. Therefore, it is urgent to design a seeder adjusting lead screw that is easy to adjust, has high adjustment accuracy, and requires little transmission force, and the lead s...
