Abstract
The utility model belongs to the technical field of seeding machinery, and discloses a four-bar linkage adjusting and locking device for a seeder. The four-bar linkage adjusting and locking device is mainly technically characterized by comprising a front rack and a rear rack, wherein a four-bar linkage device composed of an upper connecting rod, a lower connecting rod, a front rack fixing connecting rod and a rear rack fixing connecting rod is arranged between the front rack and the rear rack; a sliding inner rod with a spring is arranged between the upper connecting rod and the lower connecting rod; a fixing hole and a sliding slot are formed at the upper end of the sliding inner rod; a lock sleeve is arranged at the upper part of the sliding inner rod; a plurality of locking holes matched with the fixing hole and the sliding slot are formed in the lock sleeve; the fixing hole is connected with the locking holes through an upper pin shaft; the sliding slot and the locking holes are connected through a lower pin shaft. By adopting the four-bar linkage adjusting and locking device for the seeder provided by the utility model, the seeding depths can be consistent when the seeder works in different land types such as plains and hills, and rugged land. Thus, the emergence rate of seeds is ensured.
Description
Technical field
The utility model belongs to seeding machinery technical field, relates in particular to a kind of sower four connecting rod adjusting and locking mechanisms.
Background technology
The corn subsoiling sower of current use, its structure comprises forebay and afer bay, is provided with four linkages of connecting rod, lower link, forebay stationary links, afer bay stationary links formation between forebay and afer bay.Four linkages make afer bay upper and lower porpoising along with the injustice of physical features, ensure sowing effect.But this four linkages can not be adjusted the degree of depth locking according to the difference in plot, and seeding quality is had to certain influence.
Utility model content
Problem to be solved in the utility model is just to provide a kind of sower four connecting rod adjusting and locking mechanisms that can adjust according to the difference in plot the degree of depth locking.
For addressing the above problem, the technical solution adopted in the utility model is: comprise forebay and afer bay, between forebay and afer bay, be provided with connecting rod, lower link, forebay stationary links, four linkages that afer bay stationary links forms, described upper connecting rod, between lower link, be provided with bar in the slip of spring, in sliding, bar upper end has fixing hole, sliding tray, in sliding, bar top is provided with lock collar, lock collar has multiple and fixing hole, the lock hole that sliding tray matches, fixing hole is connected by upper pin with lock hole, sliding tray is connected by lower bearing pin with lock hole.
When sower four connecting rod adjusting and locking mechanisms provided by the utility model use, upper pin is taken off from fixing hole and lock hole, according to the difference in plot, lower bearing pin is moved up and down along sliding tray, arrive after desired height, upper pin is passed and locked from fixing hole and lock hole.Sower four connecting rod adjusting and locking mechanisms provided by the utility model, can make the sower geology different on Plain or hills etc. and the sowing of rugged plot time, sowing depth is consistent, thereby ensures the emergence rate of seed.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model sower four connecting rod adjusting and locking mechanisms;
Fig. 2 is the structural representation of four linkages;
Fig. 3 is the structural representation of bar in sliding;
Fig. 4 is the structural representation of lock collar.
Embodiment
Below in conjunction with accompanying drawing, structure and the embodiment of the utility model sower four connecting rod adjusting and locking mechanisms are described further.
As shown in Figure 1, the utility model sower four connecting rod adjusting and locking mechanisms comprise forebay 1 and afer bay 2, are provided with four linkages 3 between forebay 1 and afer bay 2.As shown in Figure 2, four linkages 3 are made up of upper connecting rod 4, lower link 5, forebay stationary links 6, afer bay stationary links 7, upper connecting rod 4,5 of lower links are provided with bar 9 in the slip of spring 8, in sliding, bar 9 tops are provided with lock collar 10, and in sliding, bar 9 is connected by upper pin 11, lower bearing pin 12 with lock collar 10.As shown in Figure 3, in slip, bar 9 upper ends have fixing hole 13, sliding tray 14.As shown in Figure 4, lock collar 10 has multiple lock holes 15.
Sower four connecting rod adjusting and locking mechanisms provided by the utility model, upper connecting rod 4,5 of lower links are provided with bar 9 in the slip of spring 8, in sliding, bar 9 upper ends have fixing hole 13, sliding tray 14, in sliding, bar 9 tops are provided with lock collar 10, lock collar 10 has multiple lock holes 15 that match with fixing hole 13, sliding tray 14, fixing hole 13 is connected by upper pin 11 with lock hole 15, and sliding tray 14 is connected by lower bearing pin 12 with lock hole 15.When use, upper pin 11 is taken off from fixing hole 13 and lock hole 15, according to the difference in plot, lower bearing pin 12 is moved up and down along sliding tray 14, arrive after desired height, upper pin 11 is passed and locked from fixing hole 13 and lock hole 15.Sower four connecting rod adjusting and locking mechanisms provided by the utility model, can make the sower geology different on Plain or hills etc. and the sowing of rugged plot time, sowing depth is consistent, thereby ensures the emergence rate of seed.
Protection domain of the present utility model is not only confined to above-described embodiment, as long as identical with the utility model sower four connecting rod adjusting and locking mechanism structures, just drops on the scope of the utility model protection.
