Referring to fig. 2-6, in some embodiments of the invention, separation mechanism 400 includes a sifting bin 410, a propulsion drum 420, a brush pot 430, a third rotary drive mechanism 440, and a blanking hopper 450.

The pushing cylinder 420 is rotatably installed in the screening box 410 along the axis thereof, the pushing cylinder 420 comprises a pushing shaft 421 and a blanking shaft 422, the blanking shaft 422 is coaxially connected to one end of the pushing shaft 421, the diameter of the blanking shaft 422 is smaller than that of the pushing shaft 421, and spiral blades 423 are arranged on the peripheral wall of the pushing shaft 421; the brush cylinder 430 is rotatably installed in the screening box 410 along the axis thereof, and the brush cylinder 430 is disposed at one side of the pushing cylinder 420, and a screening space 431 for supporting materials is formed between one side of the upper end of the brush cylinder 430, which is close to the pushing cylinder 420, and the pushing cylinder 420.

The third rotation driving mechanism 440 is configured to drive the pushing cylinder 420 and the brush cylinder 430 to rotate, and the rotation directions of the pushing cylinder 420 and the brush cylinder 430 are opposite, and the rotation of the pushing cylinder 420 and the brush cylinder 430 both drive the material in the screening space 431 to have a tendency to move obliquely upwards, as shown in fig. 5, the pushing cylinder 420 and the brush cylinder 430 are arranged at a left-right interval, the pushing cylinder 420 rotates anticlockwise, and the brush cylinder 430 rotates clockwise. It will be appreciated that the seeds are generally solid, high in density, and the shells are hollow and arched in structure and low in density, and that the outer surfaces of the seeds are generally smooth, for example, the oil tea fruit seeds are smooth in surface, and the shell is saw-toothed in fracture position and high in friction force after being shelled; the shells of the sifting space 431 are typically thrown to both sides by the pushing cylinder 420 and the brushing cylinder 430, so that the shells are separated from the sifting space 431, and effective separation is achieved by utilizing the characteristics of the shells and seeds. The third rotary driving mechanism 440 drives the pushing cylinder 420 to rotate so as to drive the material in the screening space 431 to advance towards the blanking shaft 422, so that the material can be screened and separated and simultaneously can move towards the blanking shaft 422, the seeds mixed with the shells are continuously separated in the advancing process, and the final separation and sorting effects are ensured. The blanking hopper 450 is located above the end of the pushing shaft 421 away from the blanking shaft 422, and is used for feeding materials towards the screening space 431, i.e. one end of the pushing shaft 421 is located below the blanking hopper 450, the other end of the pushing shaft is connected with the blanking shaft 422, a blanking port is formed in the bottom of the blanking hopper 450, and the blanking port is located right above the screening space 431. The blanking hopper 450 interfaces specifically with the seed hull buffering device 600 and receives the shelled seed hull mix. The material (shell and seed) is received by the screen space 431 formed by the pushing cylinder 420 and the brush cylinder 430, and the friction force moving toward both sides is applied to the material of the screen space 431 by the reverse rotation of the pushing cylinder 420 and the brush cylinder 430, so that the separation of the shell and the seed is realized, when the material is about to be separated from the pushing shaft 421 and enter the region of the blanking shaft 422, the shell is separated, the seed enters the region of the blanking shaft 422, and the seed can directly drop from the side of the blanking shaft 422 due to the fact that the diameter of the blanking shaft 422 is smaller than that of the pushing shaft 421, so that the blanking of the seed is realized. In addition, the peripheral wall of the blanking shaft is a cylindrical surface and continuously rotates, and seeds cannot be accumulated on the blanking shaft.

During the decortication process, some oil tea fruits which are not successfully decorticated may be mixed, so that during sorting, the oil tea fruits which are not successfully decorticated are easy to discharge together with seeds, and in order to further improve the separation and sorting function, referring to fig. 4, the pushing shaft 421 includes a feeding section 4211, a screening section 4212 and a screening section 4213 sequentially arranged along a direction towards the blanking shaft 422, wherein the feeding section 4211 is used for receiving the material dropped from the dropping hopper 450, that is, the section screening space 431 corresponding to the feeding section 4211 is used for receiving the material dropped from the dropping hopper 450; the screen housing segment 4212 and brush drum 430 rotate to separate the housing out of the screen space 431; the screen section 4213 and brush drum 430 rotate to separate the unpeeled fruit out of the screen space 431, thereby effecting a successive separation of the material.

Specifically, the brush 437 is disposed around the circumference of the brush cylinder 430, and when the brush cylinder 430 rotates at a high speed, a dense friction surface 4371 is formed on the circumference of the brush 437, so as to increase friction force for the material in the screening space 431. However, when the brush cylinder 430 applies force to the material through the brush 437, the brush 437 can be inserted into the bottom of the material to pull the material together, not only simply by friction, but also to brush the finely divided slag out together with the shell. It will be appreciated that the peripheral wall of the propulsion cylinder 420 is not smooth, but is roughened to provide friction to the material to effect material separation.

Referring to fig. 4, in a further embodiment of the invention, the pitch of the helical blades 423 of the sifting shell segment 4212 is greater than the pitch of the helical blades 423 of the sifting fruit segment 4213, the pitch of the helical blades 423 of the sifting fruit segment 4213 is less than the diameter of the unpeeled fruit entering from the blanking hopper 450, and the diameter of the shelled seed 4202 is less than the pitch of the helical blades 423 of the sifting fruit segment 4213, which may be embedded in the pitch of the helical blades 423. As shown in fig. 6, when the unpeeled fruit 4201 enters the fruit screening section 4213, the unpeeled fruit 4201 cannot be caught in the pitch of the spiral blades 423 but is lifted by the spiral blades 423, and the unpeeled fruit contacts the outer peripheral wall of the spiral blades 423. Compared with the situation that the seeds 4202 are in contact with the peripheral wall of the propeller shaft 421, the distance between the unpeeled fruits 4201 and the axis of the propeller shaft 421 is farther, the contact position between the unpeeled fruits 4201 and the spiral blades 423 is higher, and the component force of the friction force is distributed to the horizontal direction more, so that the friction force of the unpeeled fruits 4201 is greater than that of the seeds 4202, and the unpeeled fruits 4201 are supported by the spiral blades 423, so that a larger gap exists between the unpeeled fruits 4201 and the peripheral wall of the fruit screening segment 4213, and the unpeeled fruits 4201 are conveniently inserted under the unpeeled fruits 4201 and rotated upwards to be pulled up, and then the unpeeled fruits 4201 are better driven by the fruit screening segment 4213 to be thrown out of the screening space 431 from the side, and the unpeeled fruits 4201 in materials can be separated, so that the influence on the subsequent processing is avoided. It will be appreciated that in order to enhance the screening effect, the peripheral wall of the helical blade is a friction surface or is provided with small serrations, thereby enhancing friction with the unpeeled fruit.

Referring to fig. 3, in the embodiment of the present invention, a shell discharging guide 413 is disposed below the screening box 410 corresponding to the screen shell segment 4212, and the shell discharging guide 413 is provided with two shells and is folded downward, so that shells separated from two sides of the pushing cylinder 420 and the brushing cylinder 430 are folded, and a shell collecting box can be disposed below the shell discharging guide 413, so as to collect shell materials.
