Problems solved by technology

[0002] The tractor power output devices currently appearing in China are generally led out through the main drive system, clutch, gearbox, and rear axle box. This is a reliable arrangement method for tractors with traditional structures, but the structure is relatively complicated and difficult to maintain. The box has only one power output end and cannot be matched with a multi-purpose tractor

Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings.

[0014] As shown in the accompanying drawings, the PTO gear box body 10 of the power gear box of the tractor implement of the present invention is equipped with a PTO input shaft 4, an intermediate shaft 6, a PTO power output shaft 8 and a shift fork shaft 20 through a bearing 5, and the PTO input The front end of the shaft 4 protruding from the box body is sequentially installed with the connecting flange 27, the spline pulley coupling 1, the roller chain coupling 2 and the clutch 3 from the outside to the inside. An integrated fixed gear I29; the intermediate shaft 6 is fixedly installed with an intermediate shaft driving gear 11 (its diameter is large, which can realize low-speed transmission), an intermediate shaft driven gear 12, and a fixed gear II31 connected with the intermediate shaft 6 (Its diameter is small, can realize high-speed transmission), the intermedi...

Abstract

The invention discloses a power reduction gearbox of a tractor implement. A connecting flange, a spline belt wheel coupler, a roller chain coupler and a clutch are sequentially installed at the front end of a PTO input shaft from outer side to inner side, an intermediate shaft driving gear, an intermediate driven gear and a fixed gear II are installed on an intermediate shaft, the intermediate shaft driven gear is meshed with a fixed gear I, and a linkage gear can be respectively meshed with the intermediate shaft driving gear or the fixed gear II. A gear shifting gear is installed on a PTO shaft, a driving duplex chain wheel is installed at one end of the PTO shaft, and a spline coupler is installed at the other end of the PTO shaft. A gear shifting fork is installed on a shifting fork shaft and can shift the linkage gear. The gear shifting gear is fixed to one end of the shifting fork shaft, and at least three grooves are formed in the other end of the shifting fork shaft, a steel ball and a compression spring are arranged on a PTO reduction gearbox body, wherein the steel ball extends into the corresponding groove, and the compression spring abuts against the steel ball. The gear shifting gear is pushed to move left and right through the shifting fork, and the shifting fork is connected with a gear shifting shaft assembly. The reduction gearbox is simple in structure, three-gear shifting can be achieved, double-speed output can be achieved, gear shifting operation can be performed independently, in this way, a tractor operates more reliably, and the multi-purpose requirements for the tractor can be met.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a tractor implement power reduction box applied to 30-70 horsepower tractors. Background technique [0002] The tractor power output devices currently appearing in China are generally led out through the main drive system, clutch, gearbox, and rear axle box. This is a reliable arrangement method for tractors with traditional structures, but the structure is relatively complicated and difficult to maintain. The case has only one power output end and cannot be matched with a multipurpose tractor. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a new tractor implement power reduction box, which can realize front and rear double power output, and make the operation of the tractor more stable and reliable, and the maintenance more convenient. [0004] The present invention solves the above technical probl...
