Abstract
The utility model provides an eccentric-shaft-and-screw structure. The eccentric-shaft-and-screw structure is arranged in a machine barrel, is formed by at least two screws which are meshed, and comprises a first screw and a second screw, wherein the first screw is arranged on a first eccentric shaft, and the second screw is arranged on a second eccentric shaft; the farthest eccentric points on the same cross sections of the two screws are continuously and mutually parallel to a center point; and the first screw is of a circle shape and is arranged relative to the first eccentric shaft in an eccentric mounting manner, and the axis of the first eccentric shaft is the center of one side circle in the machine barrel. The eccentric-shaft-and-screw structure provided by the utility model is especially applicable to material with larger particles and higher hardness.
Description
Technical field
The utility model relates to a kind of eccentric shaft screw-rod structure.
Background technology
Existing screw rod distributes and generally is not provided with eccentric structure, and main cause has direct relation with the physical property of material.The utility model relates generally to a kind of eccentric shaft screw-rod structure, and this eccentric shaft screw-rod structure is mainly in the more difficult material that grinds, and is as high in hardness, and granularity is large etc.
The utility model content
In order to overcome above defective, the utility model provides a kind of eccentric shaft screw-rod structure, and this screw-rod structure does not affect the installation of other components and parts, only needs the screw portion structure is improved.
For solving above technical problem, the technical scheme that the utility model provides is as follows: a kind of eccentric shaft screw-rod structure, be installed in machine barrel, described eccentric shaft screw-rod structure is twin-screw engagement at least, described screw-rod structure comprises the first screw rod and the second screw rod, described the first screw rod is installed on the first eccentric shaft, and the second screw rod is installed on the second eccentric shaft; On the same cross section of two screw rods farthest eccentric point and centre point parallel to each other continuously.
Further, the profile of described the first screw rod is circular, and its installation site is eccentric mounting means with respect to the first eccentric shaft, and the axle center of described the first eccentric shaft is the center of circle of a side circle in machine barrel.
Further, the profile of described the second screw rod is circular, and its installation site is eccentric mounting means with respect to the second eccentric shaft, and the axle center of described the second eccentric shaft is the center of circle of opposite side circle in machine barrel.
This eccentric shaft screw-rod structure that the utility model relates to is directed to that particle is large and material that matter hardness is higher is especially applicable.
Description of drawings
Fig. 1 is the utility model eccentric shaft screw-rod structure structural representation;
The 1-machine barrel; 2-the first screw rod; 3-the second screw rod; 4-the first eccentric shaft; 5-the second eccentric shaft.
The specific embodiment
As shown in Figure 1, a kind of eccentric shaft screw-rod structure is installed in machine barrel 1, the eccentric shaft screw-rod structure is twin-screw engagement at least, screw-rod structure comprises that the first screw rod 2 and the second screw rod 3, the first screw rods 2 are installed on the first eccentric shaft 4, the second screw rods 3 and are installed on the second eccentric shaft 5; On the same cross section of two screw rods farthest eccentric point and centre point parallel to each other continuously.
The profile of the first screw rod 2 is circular, and its installation site is eccentric mounting means with respect to the first eccentric shaft 4, and the axle center of described the first eccentric shaft 4 is the center of circle of a side circle in machine barrel 1.
The profile of the second screw rod 3 is circular, and its installation site is eccentric mounting means with respect to the second eccentric shaft 5, and the axle center of described the second eccentric shaft 5 is the center of circle of the interior opposite side circle of machine barrel 1.
This screw rod that the utility model relates to is simple, easily manufactured, easy for installation.
The specific embodiment described in the utility model does not consist of the restriction to the application's scope; every within the spirit and principle of the utility model design, any modification that one of skill in the art can make, be equal to and replace and within improvement etc. all should be included in protection domain of the present utility model.
