Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1 to 4, the present invention provides a technical solution: a group of corn thresher rubber rolls comprises a main rubber roll 3, an auxiliary rubber roll 4 and an adjusting rubber roll 5, wherein the main rubber roll 3 is horizontally arranged in a machine body 1, the main rubber roll 3 is rotationally connected with the inner walls of two sides of a feeding hole of the machine body 1 through a belt pulley 11 on one side of the machine body 1, and the belt pulley 11 is in transmission connection with an output shaft of a motor through a belt. The outside of the roll surface of the main rubber roll 3 is provided with spiral grooves 31, the spiral grooves 31 are distributed on the roll surface of the main rubber roll 3 at equal intervals, the spiral grooves 31 are right-handed spiral grooves, and the main rubber roll rotates anticlockwise during rotation. The main rubber roller 3 applies an acting force to the corn ears, so that the corn ears rotate anticlockwise around the axis of the main rubber roller on one hand, and the corn ears move forwards on the other hand, and continuous threshing of single ears is realized.
The both ends of vice rubber roll 4 are connected with runner 6, and runner 6 rotates with the feed inlet both sides inner wall of organism 1 to be connected, has seted up 8 first straight flute 41 on the roll surface of vice rubber roll 4, and the roll shaft bottom of vice rubber roll 4 is fixed with helical blade 42, and the running roller and the helical blade 42 coaxial setting of vice rubber roll 4. 8 second straight grooves 51 are formed in the roller surface of the adjusting rubber roller 5, the axial lead of the auxiliary rubber roller 4 and the axial lead of the main rubber roller 3 are obliquely downwards arranged at an included angle of 45 degrees, the axial lead of the adjusting rubber roller 5 and the axial lead of the main rubber roller 3 are obliquely upwards arranged at an included angle of 45 degrees, a corn threshing area is formed by a triangular area surrounded by the rubber roller of the main rubber roller 3, the rubber roller of the auxiliary rubber roller 4 and the rubber roller of the adjusting rubber roller 5, and corn ears finish threshing in the corn threshing area.
One end of a roll shaft of the adjusting rubber roll 5 rotates in a U-shaped waist groove in the distance adjusting plate 21, the distance adjusting plate 21 can adjust the rotating position of a rotating shaft through distance adjusting wheels 2 on two sides, the distance adjusting wheels 2 are rotationally connected to the inner walls on two sides of a feeding hole of the machine body 1, and the adjusting rubber roll 5 can change the space size of a corn threshing area along with the change of the diameter of corn ears in the corn threshing area.
The main rubber roller 3, the auxiliary rubber roller 4 and the adjusting rubber roller 5 have the same rotation direction, and corn ears are threshed under the kneading force of the three rubber rollers in the anticlockwise direction in a corn threshing area, so that the purpose of separating seeds from cobs is achieved. The roller surfaces of the main rubber roller 3, the auxiliary rubber roller 4 and the adjusting rubber roller 5 are made of rubber.
The rotating speed of the auxiliary rubber roller 4 is the same as that of the adjusting rubber roller 5, and the diameter of the auxiliary rubber roller 4 is not larger than that of the adjusting rubber roller 5. The three rubber rolls rotate in the same direction at a low speed, the diameter of the main rubber roll 3 is the largest, the linear speed is the highest, the rotating speed of the auxiliary rubber roll 4 is the same as that of the regulating rubber roll 5, and the diameter of the auxiliary rubber roll 4 is not larger than that of the regulating rubber roll 5, so that the linear speed of the auxiliary rubber roll 4 is the lowest. The linear speeds of the three rubber rollers acting on corn ears are different, and the rotation directions are the same. So the acting force on the corn ears is different.
The first straight groove 41 and the second straight groove 51 increase the roughness of the roller surface, the kneading effect when the roller surface is contacted with corn ears is increased, the spiral groove 31 has an axial pushing effect on the corn ears, the corn ears are pushed by the main rubber roller 3 and the adjusting rubber roller 5 and gradually tend to the auxiliary rubber roller 4, and finally, the threshed corn ears are sent away by the spiral blades 42 on the auxiliary rubber roller 4. Because the three rubber rollers enclose a triangular threshing area, the roller surface of the threshing roller is a rubber soft surface and is in flexible contact with the corn ears, the corn ears are not crushed and crushed by the threshing roller, the non-crushing threshing is realized, and the corn ears can be planted in the next year.
