Abstract
The utility model discloses a self-locking type operating mechanism of a rice transplanter clutch. The self-locking type operating mechanism comprises an operating rod, an operating box, a connecting arm, a pin and a pull rod and is characterized in that the operating rod comprises an extending part and a main rod, the extending part and the main rod are connected to form a V shape, the intersection of the V shape is connected into the operating box through the pin, the front end of the extending part is connected to the connecting arm, and a shaft sleeve sleeves the connection of the front end of the extending part and the connecting arm. The self-locking type operating mechanism has the advantages that by the blocking of the connecting arm and the pin, self-locking of the operating mechanism is achieved, impact is avoided during operation, the front end of the operating rod is less prone to abrasion due to the fact that the shaft sleeve sleeves the pin for connecting, reliability is increased, and service life is prolonged.
Description
Technical field
The utility model belongs to agricultural machinery technological field, is specifically related to a kind of transplanter clutch self-locking operating mechanism.
Background technique
The transplanter clutch operation of transplanter generally comprises operating stem, operating box, link arm, pull bar at present, operating stem is directly flexibly connected with link arm, there is following several problem in such structure: link arm is easily out of shape, operating handle easily weares and teares whole operating mechanism cisco unity malfunction was even lost efficacy with the matching part that is connected of link arm, reliability is not high, and this structure is that by block, operating mechanism self-locking, when operation to be impacted large, the quick abrasion life-span is short.
Model utility content
The purpose of this utility model is to provide that a kind of reliability is high, the transplanter clutch self-locking operating mechanism of long service life.
For realizing above-mentioned model utility object, the utility model has adopted following technological scheme:
A kind of transplanter clutch self-locking operating mechanism, comprise operating stem, operating box, link arm, bearing pin, pull bar, it is characterized in that, described operating handle comprises extension part and mobile jib, described extension part and mobile jib connect into V-shape, described V-shape intersection point place is connected in described operating box by bearing pin, and the front end of described extension part is connected in link arm, and its both joint cover has axle sleeve.
As one of preferred version, described link arm is sickleshaped, and its one end is connected in pull bar, and the other end is provided with through hole, and described through hole inner sleeve has axle sleeve, and the extension part of described operating handle penetrates and in axle sleeve, is connected and fixed on link arm.
As one of preferred version, described operating handle can drive link arm in operating box, to rotate centered by bearing pin; Described operating handle end is provided with handle.
Working principle:
By upwards, downwards manipulation operations bar can realize clutch " closing ", " from ".
When operating stem end handle upwards operates, its front end drives link arm turning anticlockwise centered by bearing pin.Now simultaneously revolution centered by operating stem front end, its other end drive pull bar to " closing " of away from bearing pin central direction moves, clutch spring being loosened to realize clutch to link arm again.
When operating stem end handle operates downwards, its front end drives link arm revolution clockwise centered by bearing pin.Now link arm simultaneously again revolution centered by operating stem front end, its other end drive pull bar to approach bearing pin central direction move and make clutch spring tension realize clutch " from ".Now link arm due to bearing pin stop, under the pulling force operation of pull bar and in self-locking position.
Beneficial effect:
Self-locking, when operation that transplanter clutch self-locking operating mechanism described in the utility model stops to realize operating mechanism by link arm and bearing pin are without impact, on the bearing pin of its connection function, cover has axle sleeve, make operating stem front end not easy to wear, increased reliability, extended working life.
Accompanying drawing explanation
Fig. 1 be the utility model transplanter clutch self-locking operating mechanism in " from " structural representation of position;
Fig. 2 is that the utility model transplanter clutch self-locking operating mechanism is in the structural representation for " closing " position
Wherein, 1, operating stem; 2, operating box; 3, link arm; 4, bearing pin; 5, pull bar; 6, axle sleeve.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the technical solution of the utility model is further described.
Embodiment:
As shown in Figure 1: a kind of transplanter clutch self-locking operating mechanism that the present embodiment discloses, comprise operating stem 1, operating box 2, link arm 3, bearing pin 4, pull bar 5, it is characterized in that, described operating handle 1 comprises extension part and mobile jib, described extension part and mobile jib connect into V-shape, described V-shape intersection point place is connected in described operating box 2 by bearing pin 4, and the front end of described extension part is connected in link arm 3, and its both joint cover has axle sleeve 6.
As one of preferred version, described link arm 3 is sickleshaped, and its one end is connected in pull bar 5, and the other end is provided with through hole, and described through hole inner sleeve has axle sleeve, and the extension part of described operating handle 1 penetrates and in axle sleeve, is connected and fixed on link arm 3.
As one of preferred version, described operating handle 1 can drive link arm 3 in operating box, to rotate centered by bearing pin 4; Described operating handle 3 ends are provided with handle.
Working principle:
By upwards, downwards manipulation operations bar can realize clutch " closing ", " from ".
As shown in Figure 2: when operating stem 1 end handle upwards operates, its front end drives link arm 3 turning anticlockwise centered by bearing pin 4.Now revolution centered by operating stem 1 front end, its other end drive pull bar 5 to " closing " of away from bearing pin 4 central directions move, clutch spring being loosened to realize clutch again simultaneously for link arm 3.
As shown in Figure 1: when operating stem 1 end handle operates downwards, its front end drives link arm 3 revolution clockwise centered by bearing pin 4.Now link arm 3 simultaneously again revolution centered by operating stem 1 front end, its other end drive pull bar 5 to approach bearing pin 4 central directions move and make clutch spring tension realize clutch " from ".Now link arm 3 due to bearing pin 4 stop, under the pulling force operation of pull bar 5 and in self-locking position.
It is to be noted; as described above is only in order to explain the preferred embodiment of the utility model; and attempt is done any formal restriction to the utility model according to this; be with; all any modification or changes that has the relevant the utility model of doing under identical practical spirit, all must be included in the category that the utility model is intended to protection.
