In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly defined.

[0028] like Figure 1-5 As shown, in one embodiment of this utility model, a separation device is provided, including a frame 10, a first screening and conveying assembly 20, and a second screening and conveying assembly 30. Both the first screening and conveying assembly 20 and the second screening and conveying assembly 30 are mounted on the frame 10. The first screening and conveying assembly 20 has a first conveying direction and has a first side 21 and a second side 22 along a direction perpendicular to the first conveying direction. The horizontal height of the second side 22 is lower than the horizontal height of the first side 21. The second screening and conveying assembly 30 is located below the second side 22 and has a second conveying direction, which is arranged in the same direction as or opposite to the first conveying direction. In this embodiment, the second conveying direction is arranged in the same direction as the first conveying direction. Figure 1 (In the direction indicated by the middle arrow). Potatoes, clods of soil, and stones are conveyed by the feeding conveyor assembly 40 and fall onto the first screening conveyor assembly 20. The falling position of the potatoes, clods of soil, and stones is close to the front end area of ​​the first conveying direction.

[0029] This embodiment discloses a separation device that, by designing the first screening and conveying assembly 20 to tilt towards the second side 22, allows potatoes, clods of soil, and stones to fall onto the first screening and conveying assembly 20. The potatoes are more likely to roll towards the second side 22 and eventually fall onto the second screening and conveying assembly 30, where they are transferred to the next process. Most of the clods of soil and stones are conveyed away by the first screening and conveying assembly 20. This effectively separates potatoes from clods of soil and stones during the conveying process, improving harvest quality and simplifying the overall structure of the harvester.

[0030] In one embodiment, the second screening and conveying assembly 30 has a third side 31 and a fourth side 32 along a direction perpendicular to the second conveying direction. The third side 31 is close to the first screening and conveying assembly 20, and the fourth side 32 is provided with a first baffle 11 extending along the second conveying direction. The first baffle 11 is designed to block potatoes rolling off the first screening and conveying assembly 20, thereby trapping the potatoes on the second screening and conveying assembly 30.

[0031] In one embodiment, in order to block the potatoes falling from the feeding conveying assembly 40 so that they all fall onto the first screening conveying assembly 20, a second baffle plate 12 is provided on the first side 21, and the second baffle plate 12 extends along the first conveying direction.

[0032] In one embodiment, the first screening and conveying assembly 20 has a first conveying surface 23, and the second screening and conveying assembly 30 has a second conveying surface 33, with the projections of the first conveying surface 23 and the second conveying surface 33 on a horizontal plane coinciding. This structural design ensures that potatoes can roll from the first screening and conveying assembly 20 onto the second screening and conveying assembly 30. Simultaneously, it also reduces the space occupied by the first screening and conveying assembly 20 and the second screening and conveying assembly 30.

[0033] In one embodiment, the first screening and conveying assembly 20 includes two first drive belts 24 and multiple first rods 25, with each end of a first rod 25 connected to one of the two first drive belts 24. The second screening and conveying assembly 30 includes two second drive belts and multiple second rods, with each end of a second rod connected to one of the two second drive belts. The frame 10 is equipped with two first auxiliary pulleys and two second auxiliary pulleys, with each first drive belt 24 wound around its corresponding first auxiliary pulley and each second drive belt wound around its corresponding second auxiliary pulley. The separation device also includes two drive assemblies 50, which drive the first drive belts 24 and the second drive belts to rotate.

[0034] Specifically, the drive assembly 50 includes a rotating shaft 51, a motor (not shown in the attached drawings), and two drive wheels 52. The rotating shaft 51 is rotatably mounted on the frame 10, and the motor is fixed on the frame 10 and connected to the rotating shaft 51. The two drive wheels 52 are respectively mounted on the rotating shaft 51, and the outer circumferential wall of the drive wheels 52 is evenly provided with a plurality of grooves 521, which can cooperate with the first rod 25 or the second rod.

[0035] When the motor starts, it drives the rotating shaft 51 and the two drive wheels 52 to rotate synchronously. During the rotation of the drive wheels 52, the groove 521 will cooperate with the first rod 25 or the second rod, thereby driving the two first transmission belts 24 or the two second transmission belts to rotate. In this way, the first screening component and the second screening component are driven. At the same time, the structural design of the first screening and conveying component 20 and the second screening and conveying component 30 allows some soil or small clods of earth and stones to fall directly from the gaps (the gaps between two adjacent first rods 25 or the gaps between two adjacent second rods), thus improving the separation effect.

[0036] In one embodiment, the drive assembly 50 further includes two mounting seats 53, which are fixed to the rotating shaft 51. Each mounting seat 53 is connected to a corresponding drive wheel 52. The mounting seat 53 has four screw holes, while the drive wheel 52 has four elongated arc-shaped holes 522, each corresponding to a screw hole. The mounting seat 53 and the drive wheel 52 are securely connected by four bolts 54 passing through the screw holes and elongated arc-shaped holes 522. This structural design allows the drive wheel 52 to rotate a certain amount around its own axis, thereby adjusting the relative position of the drive wheel 52 and the mounting seat 53, so that the groove 521 of the drive wheel 52 can be adapted to the position of the first rod 25 or the second rod.

[0037] This embodiment also provides a harvester, including the aforementioned separating device. Because it employs the separating device described above, it has the same working principle and technical effects as the separating device in the above embodiments, and will not be repeated here.

[0038] Numerous specific details are set forth in this specification. However, it will be understood that embodiments of this invention may be practiced without these specific details. In some instances, well-known methods, structures, and techniques have not been shown in detail so as not to obscure the understanding of this specification.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
