Abstract
The utility model discloses a combined harvester threshing chamber inlet sealing device which comprises a sealing flat belt installed on the rear portion of a gap bridge and further comprises a transitional sealing plate riveting piece and an elastic component. The transitional sealing plate riveting piece and the elastic component are arranged below an inlet of a threshing chamber, the elastic component is arranged below the transitional sealing plate riveting piece and always keeps contact with the transitional sealing plate riveting piece, the transitional sealing plate riveting piece is in rotatable connection with the threshing chamber, and under the elastic force effect generated by the elastic component, the transitional sealing plate riveting piece always keeps contact with the sealing flat belt. Compared with the prior art, the sealing device has the advantages that the combined action of a compressed spring and the sealing flat belt is adopted, when a gap bridge rotates to any position, the ideal sealing effect can be achieved, after elastic deformation of the sealing flat belt occurs, the sealing flat belt can not be timely restored, or when plastic deformation of the flat belt occurs, the transitional sealing plate riveting piece can keep tight contact with the sealing flat belt by relying on the pressure generated by the compressed spring, and good sealing of a connection is ensured.
Description
Technical field
The utility model relates to agricultural machinery, and specifically, the utility model relates to a kind of threshing room of combine inlet seal device.
Background technology
At present, following structure is adopted in the sealing of domestic threshing room of combine entrance and gap bridge junction: arc plate of below, threshing chamber porch welding, flat belt is equipped with in gap bridge deutostoma and threshing chamber junction, after gap bridge is articulated in above threshing chamber, flat belt produces strain and is pressed on arc plate, form sealing system, prevent from when cereal feeds, occurring to leak the grain phenomenon.
The main shortcoming of above-mentioned hermetically-sealed construction is: 1, the accuracy of manufacture of arc plate is had relatively high expectations; In case 2, flat belt can not change the elastic deformation amount in time along with the variation in gap during taiwan cut off and landing, or after using a period of time, flat belt produces plastic deformation because of fatigue, loses sealing function.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of threshing room of combine inlet seal device that is not easy to lose efficacy.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of threshing room of combine inlet seal device, comprise the sealing flat belt that is arranged on the gap bridge rear portion, also comprise the transition sealing plate riveted spare and the elastic parts that are located at below, threshing chamber porch;
Elastic parts is positioned at the below of transition sealing plate riveted spare, and with transition sealing plate riveted spare, keeps in touch all the time;
Transition sealing plate riveted spare is rotationally connected with threshing chamber, and transition sealing plate riveted spare keeps in touch with described sealing flat belt all the time under the resilient force that elastic parts produces.
Described elastic parts comprises the press spring base soldering member, is located at the spring base on the press spring base soldering member and is located at the stage clip on spring base, and stage clip keeps in touch with described transition sealing plate riveted spare all the time.
Described transition sealing plate riveted spare is arranged on described threshing chamber by rotating shaft.
The utility model adopts technique scheme, compared with prior art, this sealing device adopts stage clip and the acting in conjunction of sealing flat belt, guarantee can arrive desirable sealing effectiveness when gap bridge turns to any position, after sealing flat belt generation strain, can not recover in time or flat belt generation plastic deformation in, the pressure that can rely on stage clip to produce, make transition sealing plate riveted spare and sealing flat belt keep close contact, guarantees the excellent sealing of interface.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Mark in above-mentioned figure is: 1, threshing chamber; 2, transition sealing plate riveted spare; 3, rotating shaft; 4, press spring base soldering member; 5, stage clip; 6, sealing flat belt; 7, pass a bridge.
Embodiment
Be illustrated in figure 1 a kind of threshing room of combine inlet seal device of the present utility model, it comprises the sealing flat belt 6 that is arranged on 7 rear portions of passing a bridge, transition sealing plate riveted spare 2 and the elastic parts that is located at threshing chamber 1 below, porch; Elastic parts is the below that is positioned at transition sealing plate riveted spare 2, and with transition sealing plate riveted spare 2, keeps in touch all the time; Transition sealing plate riveted spare 2 is rotationally connected with threshing chamber 1, and transition sealing plate riveted spare 2 keeps in touch with described sealing flat belt 6 all the time under the resilient force that elastic parts produces.
As shown in Figure 1, the elastic parts of the present embodiment comprises press spring base soldering member 4, is located at the spring base on press spring base soldering member 4 and is located at the stage clip 5 on spring base, stage clip 5 keeps in touch with transition sealing plate riveted spare 2 all the time, by transition sealing plate riveted spare 2 jack-up, guarantee that transition sealing plate riveted spare 2 remains and contacts with sealing flat belt 6.Spring base is evenly equipped with several on press spring base soldering member 4, press spring base soldering member 4 use bolted are on threshing chamber 1.
As shown in Figure 1, transition sealing plate riveted spare 2 is arranged on threshing chamber 1 by rotating shaft 3, and can take rotating shaft 3 and be the pivot rotation, and rotating shaft 3 is welded on threshing chamber 1.
During work, gap bridge 7 is articulated in above threshing chamber 1, and the sealing flat belt 6 at 7 rear portions of passing a bridge is pressed in above transition sealing plate riveted spare 2, utilizes strain and the stage clip 5 that sealing flat belt 6 produces to be out of shape the support force that transition sealing plate riveted spare 2 is provided, reach the effect of sealing, be not easy to lose efficacy.
The above is exemplarily described the utility model by reference to the accompanying drawings; obviously the utility model specific implementation is not subject to the restrictions described above; the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out as long as adopted; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
