Description

TECHNICAL FIELD

[0001] The utility model relates to the related technical field of stem pulling roller, and specifically relates to a stem pulling roller improving stem pulling efficiency. BACKGROUND

[0002] In the field of agricultural mechanization operation, especially in the harvesting process of crops such as corn and sorghum, the stem pulling roller plays a crucial role. With the continuous expansion of agricultural planting scale and the increasing demand for harvesting efficiency, the stem pulling efficiency of the traditional stem pulling roller has been difficult to meet the needs of modern agricultural production. In the large-scale operation scene, the lower stem pulling efficiency means a longer harvesting period, which not only increases the labor time and cost of farmers, but also may affect the quality of crops and subsequent storage and processing due to delayed harvesting.

[0003] The existing stem pulling roller has several stem pulling knives distributed in the circumferential direction. There are various combinations of sawtooth-shaped, round-toothed and ordinary stem pulling knives on the market, but when the moisture of corn plants is relatively large or extremely small, the plants are prone to breakage during the stem pulling process, thereby affecting the harvesting efficiency. Therefore, in view of the above status, it is urgent to provide a stem pulling roller that improves stem pulling efficiency to overcome the shortcomings in current practical applications. SUMMARY

[0004] The utility model aims at overcoming the shortcomings of the above-mentioned traditional technology, providing a stem pulling roller that improves stem pulling efficiency, and aims to solve the problems in the above-mentioned background technology.

[0018] Embodiment: refer to Figure 1 and Figure 2 A stem pulling roller for improving stem pulling efficiency, the stem pulling roller for improving stem pulling efficiency comprises a pipe shaft 5 and a guide cone 1, the guide cone 1 and the pipe shaft 5 are connected through a mounting seat 2, and the pipe shaft 5 is further provided with a tooth-shaped stem pulling knife 3 and an ordinary stem pulling knife 4.

[0019] The tooth-shaped stem pulling knife 3 and the ordinary stem pulling knife 4 are both provided with a plurality of groups in the circumferential direction of the pipe shaft 5.

[0020] The tooth shape of the tooth-shaped stem pulling knife 3 is a trapezoidal shape.

[0021] The outer angle of the protruding position at the knife edge of the tooth-shaped stem pulling knife 3 is an obtuse angle, and the inner angle of the recessed position is an obtuse angle.

[0022] The mounting seat 2 and the pipe shaft 5 are rotationally connected, the mounting seat 2 can rotate around the center line of the pipe shaft 5 shaft, and the mounting seat 2 can move in the axial direction of the pipe shaft 5 within a small range.

[0023] In the embodiment of the present application, through the special tooth shape of the tooth-shaped stem pulling knife 3, the protruding tooth shape has good straw grabbing capacity, the recessed position can also assist in straw grabbing, so that the plant straw is not easy to break, thereby improving the harvesting efficiency.

[0024] In one embodiment of the present application, refer to Figure 1 , the mounting seat 2 is made of nodular cast iron.

[0025] The pipe shaft 5 is made of Q235-A.

[0026] In the embodiment, Q235-A has good strength and toughness, can bear larger structural load, facilitates to improve the service life of the pipe shaft 5, and the nodular cast iron is a high-strength cast iron material, the graphite form of which is spherical, and the comprehensive mechanical property is close to steel, which can improve the strength of the mounting seat 2.
