Description

Rice thresher tripterygium cylinder and rice thresher

Technical Field

The utility model relates to a cylinder, in particular to a rice thresher and a cylinder of tripterygium thereof.

Background

China is a large country for rice production, and particularly in southern areas of China, rice planting is often used as the most common grain production.

The southern areas of China are mostly mountainous and hilly areas, the land is relatively dispersed, and the rice harvesting and threshing can not adopt large-scale machinery but only adopt manual work or small-scale machinery for harvesting. The common rice threshing machine is too simple and light in structure, so that threshing is not clean, and waste is caused. Especially, most of the southern areas are late rice, the ears are strong, and the rice is not easy to separate from the rice stems, thereby causing further waste.

Therefore, the technical personnel in the field are dedicated to developing a rice thresher and a tripper roller thereof, which not only has simple and light structure and better threshing effect, but also reduces the waste of rice threshing.

SUMMERY OF THE UTILITY MODEL

In view of the above-mentioned defects of the prior art, the technical problem to be solved by the present invention is to provide a tripper cylinder of a rice thresher and a rice thresher, which not only have simple and light structure, but also have better threshing effect and reduce the waste of rice threshing.

In order to achieve the purpose, the utility model provides a rice thresher qupu cylinder, including the axis of rotation, first baffle and second baffle are installed respectively to the axis of rotation both ends, install a plurality of connecting rods between first baffle and the second baffle, the connecting rod is circumference evenly distributed, be provided with bellied portion of threshing on the connecting rod. The connecting rods are evenly distributed on the circumference, the rotation is stable, the centrifugal force is reduced, the convex threshing part can effectively accelerate the threshing of rice, and the efficiency is improved.

Furthermore, at least one threshing rod is arranged on the connecting rod. The threshing rod is used for not only threshing rice, but also guiding the rice to the threshing part for threshing in the rotating process of the roller.

Furthermore, a third baffle is arranged between the first baffle and the second baffle and close to the second baffle.

Furthermore, each connecting rod between the second baffle and the third baffle is provided with a vane plate. The wind blade plate generates wind force in the rotating process, and the threshed rice stems are blown out of the thresher.

Furthermore, a support rod is arranged between each connecting rod and the rotating shaft. The bracing piece strengthens the holding power between each connecting rod, prevents that the connecting rod from warping too greatly.

Further, the device also comprises a bearing arranged on the rotating shaft. The bearing makes the axis of rotation rotate steadily, reduces the friction.

Furthermore, the device also comprises a belt pulley arranged on the rotating shaft. The belt pulley is used for being connected with the power device and transmitting power.

Furthermore, 4 connecting rods are arranged between the first baffle and the second baffle.

Furthermore, the utility model also comprises a rice thresher with the rice thresher tripper roller.

The utility model has the advantages that: the utility model is provided with the convex threshing part, compared with the prior rice thresher roller, the threshing efficiency is high, and the threshing effect is better; the fan blade plates are arranged between the baffles, so that the rice stems can be quickly blown out of the thresher, and the thresher is convenient and quick.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples, wherein it is noted that, in the description of the invention, the terms "upper", "lower", "left", "right", "inner", "outer", etc. indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular manner, and therefore should not be construed as limiting the present invention. The terms "first," "second," "third," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "communicating" are to be construed broadly, e.g., as meaning fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in figure 1, the tripterygium cylinder of the rice thresher comprises a rotating shaft 1, wherein a first baffle 2 and a second baffle 3 are respectively arranged at two ends of the rotating shaft 1, and the second baffle 3 is not only used for isolating rice stems, but also used for supporting the cylinder. The bearing 9 and the belt pulley 10 are installed on the rotating shaft 1, the bearing 9 is mostly a ball bearing, rolling friction force in the rotating process of the rotating shaft 1 is reduced, the belt pulley 10 is mostly a triangular belt pulley, and friction force is large.

Install a plurality of connecting rods 5 between first baffle 2 and the second baffle 3, in this embodiment, install 4 connecting rods 5 between first baffle 2 and the second baffle 3, connecting rod 5 is circumference evenly distributed, and circumference evenly distributed's connecting rod 5 can effectually reduce centrifugal force at the rotation in-process, improves the life of cylinder. The connecting rod 5 is provided with a convex threshing part 7, the connecting rod 5 is provided with at least one threshing rod 6, and the threshing rod 6 is not only used for threshing rice, but also used for guiding the rice to the threshing part 7 for threshing in the rotating process of the roller.

A third baffle 4 is arranged between the first baffle 2 and the second baffle 3 and close to the second baffle 3, a vane 8 is arranged on each connecting rod 5 between the second baffle 3 and the third baffle 4, the vane 8 generates wind power in the rotating process of the roller, threshed rice stems are quickly blown out of the thresher, and blockage is reduced. Supporting rods 11 are arranged between the connecting rods 5 and the rotating shaft 1, and the supporting rods 11 prevent the rotary drum from deforming too much in the rotating process to influence the threshing effect.
