Abstract
A seeding machine with an air spring four-bar linkage mechanism belongs to the technical field of agricultural machinery. The seeding machine is characterized in that a spring pressure plate is mounted on a crossbeam for fixing the four-bar linkage mechanism; a swaying shaft is fixed on an upper bar of the four-bar linkage; a spring support plate is fixed on the swaying shaft; and an air spring is fixed between the spring support plate and the spring pressure plate. The seeding machine with the air spring four-bar linkage mechanism has the advantages of more compact and reasonable structure because the space occupied by the spring on the four-bar linkage mechanism is reduced. The tension force of the air spring can be adjusted to ensure stable and reliable operation of the seeding machine.
Description
Technical field
The utility model belongs to agricultural machinery technological field.
Background technology
At present, the quadric chain that known sower is installed all adopts the helical spring tensioning, and such mechanism's occupation space is big, and tensile force can not be adjusted.
Summary of the invention
The purpose of this utility model is: a kind of sower with gas spring quadric chain is provided.It has not only dwindled structural volume, can adjust effectively tensile force simultaneously.
The technical solution of the utility model is: a spring bearer plate is installed on the crossbeam of fixing quadric chain, on connecting rod on four connecting rods, fix a swinging axle, fix a spring planet on the swinging axle, gas spring is fixed between spring planet and the spring bearer plate.Gas pressure in the adjustments of gas spring can change the rigidity of gas spring, thereby has changed the tensile force of gas spring.
The beneficial effects of the utility model are: this has the sower of gas spring quadric chain, and the space that the spring on the quadric chain occupies diminishes, and structure is compact more, reasonable.The tensile force of gas spring can be adjusted, and makes sower stable working, reliable.
Description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is that A of the present utility model is to view.
Installation diagram when Fig. 3 is gas spring work on four connecting rods.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in the figure, the 1st, feed mechanism, the 2nd, transmission mechanism, the 3rd, spring bearer plate, the 4th, crossbeam, the 5th, fertile case, the 6th, tractating bar, the 7th, fertilizing mechanism, the 8th, land wheel, 9 is lower links of four connecting rods, the 10th, gas spring 11 is to connect bearing pin, and 12 is last connecting rods of four connecting rods, the 13rd, and swinging axle, the 14th, spring planet.
In Fig. 1, last connecting rod and lower link that feed mechanism 1 usefulness connects bearing pin 11 4 connecting rods are fixed on (referring to Fig. 3) on the crossbeam 4, and the power of transmission mechanism 2 is sent to respectively on feed mechanism 1 and the fertilizer mechanism 7, and spring bearer plate 3 is fixed on the crossbeam 4.
In Fig. 2, swinging axle 13 is fixed on the last connecting rod 12 of four connecting rods, fixes a spring planet 14 on the swinging axle, fixed gas spring 10 between spring planet 14 and spring bearer plate 3.
In Fig. 3, during work, gas spring 10 inflations are clipped between spring planet 14 and the spring bearer plate 3.
The tensile force of gas spring 10 is adjusted with the air pressure in the gas spring 10.
