Detailed Description
The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. A tension spring type four-bar mechanism for quickly regulating the pressure of a single body for fertilizing and seeding to the ground is characterized in that a parallel four-bar mechanism consisting of two upper connecting bars 4 and two lower connecting bars 8 which are symmetrically arranged is hinged on the rear part of a U-shaped mounting frame 1 in a manner of swinging up and down, the rear part of the parallel four-bar linkage is hinged with a single fertilizing and seeding frame 6, N grooves 5 are symmetrically arranged on the upper end parts of two upper connecting bars 4 which are symmetrically arranged from front to back, axial limiting baffles 3 are fixedly mounted at two end parts of a tension adjusting plate 11 respectively, bosses 10 are fixedly mounted on the outer end surfaces of two sides of the tension adjusting plate 11 at intervals of 180 degrees along the circumferential direction respectively, the tension adjusting plate 11 is supported and mounted on two upper connecting rods 4 by utilizing the clamping fit of the bosses 10 and grooves 5, and the outer end surfaces of the axial limiting baffles 3 are matched with the inner side surfaces of the upper connecting rods 4; the front and the rear parts of two lower connecting rods 8 which are symmetrically arranged are parallel to each other and are respectively supported and fixedly installed with a front plate seat 9 and a rear plate seat 7, the upper end of a tension spring 2 is hung on a tension adjusting plate 11, and the lower end of the tension spring 2 is hung on the front plate seat 9 or the rear plate seat 7.
When increasing the pressure of the single body for fertilizing and seeding to the ground, articulate the lower extreme of extension spring 2 on front bezel seat 9, utilize the roll retrusion of tension adjusting plate 11, according to the regulation needs, make boss 10 be the card with the recess 5 of rear side position and go into the locking cooperation, extension spring 2 lengthens this moment, the pulling force increases, moment based on last connecting rod 4 and 1 hinge point of U-shaped mounting bracket is greater than the moment of lower connecting rod 8 and 1 hinge point of U-shaped mounting bracket, under the control cooperation of single body frame for fertilizing and seeding 6, the parallel four-bar linkage that comprises last connecting rod 4 and lower connecting rod 8 drives single body frame for fertilizing and seeding 6 and moves down wholly, reduce with ground height distance, the overdraft to ground has been increased.
