DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail in conjunction with the drawings.

[0024] As Figures 1 to 3 shown, in an embodiment provided by the present utility model, a primary conveying device includes a conveying seat 1 and a conveying roller 2. A plurality of conveying rollers 2 are uniformly installed at the top end of the conveying seat 1 in a rotational mating manner. It is characterized in that: it further includes a conveying circular plate 3. A plurality of conveying circular plates 3 are uniformly installed on each of the conveying rollers 2 along the axial direction thereof, and the conveying circular plates 3 uniformly arranged on two adjacent conveying rollers 2 are spaced from each other.

[0025] Specifically, the conveying seat 1 is a mounting seat for mounting the conveying rollers 2 and the conveying circular plates 3. At the bottom end of the conveying seat 1, two discharge plates 4 are symmetrically mounted. The discharge plates 4 are two mutually symmetric inclined plates. The openings of the two discharge plates 4 close to the top end of the conveying seat 1 are larger than their openings away from the top end of the conveying seat 1. There is a certain gap between each conveying roller 2. The conveying circular plates 3 uniformly arranged between two adjacent conveying rollers 2 are spaced from each other (that is, there is a certain gap between the conveying circular plates 3 on the conveying rollers 2, and the conveying circular plates 3 on the adjacent conveying rollers are located in the gaps between the conveying circular plates 3 on the adjacent conveying rollers). The gap between the conveying circular plates 3 is used for discharging the soil adhered to the surface of the potatoes. One end of each conveying roller 2 penetrates through the conveying seat 1, and a synchronous pulley 5 is mounted at each end of each conveying roller 2 penetrating through the conveying seat 1. The synchronous pulleys 5 are connected by a synchronous belt 6; a driving member 7 is mounted on the outer wall of the conveying seat 1, and the output end of the driving member 7 is connected to the synchronous pulley 5 on one of the conveying rollers 2; when the conveying rollers 2 and the conveying circular plates 3 need to convey the potatoes, the driving member 7 (the driving member 7 is a device with a driving end that rotates forward and backward, preferably a motor) is started to drive the synchronous pulley 5 connected to it to rotate clockwise. Since the synchronous pulleys 5 are connected by the synchronous belt 6, each synchronous pulley 5 is driven by the synchronous belt 6, so that the synchronous belt 6 drives each synchronous pulley 5 to rotate synchronously, so that each synchronous pulley 5 drives the conveying rollers 2 and the conveying circular plates 3 to rotate, so that the conveying circular plates 3 rotate and convey the potatoes. Since the potatoes are rotated and conveyed on the conveying circular plates 3, the potatoes can rotate on the rotating circular plates, and during the rotation of the potatoes, the rotating circular plates can rotate and clean the soil adhered to the outer walls of the potatoes, so that the soil on the surface of the potatoes can be cleaned. The soil on the potatoes can fall from the gap between the conveying circular plates 3 onto the discharge plates 4. Since the openings of the two discharge plates 4 close to the top end of the conveying seat 1 are larger than their openings away from the top end of the conveying seat 1, the discharge plates 4 can collect the soil and convey it to the ground for collecting and recycling the soil; in the prior art, when excavating and collecting potatoes, a potato harvester is needed to perform the excavating and collecting operation on the potatoes. Since a large amount of soil usually adheres to the outer walls of the potatoes after they are excavated from the soil, when the conveying device conveys the potatoes through the conveyor belt, it cannot clean the soil adhered to the potatoes, so that there is more soil adhered to the surface of the harvested potatoes, and subsequent cleaning operations need to be carried out by the staff;In this embodiment, by synchronously driving the rotation of the conveying roller 2 and the conveying circular plate 3, the conveying roller 2 and the conveying circular plate 3 can perform the conveying operation on the potatoes. At the same time, since the conveying circular plates 3 uniformly arranged on two adjacent conveying rollers 2 are spaced from each other, the potatoes can vibrate and roll on the conveying circular plates 3, so that the soil adhered to the potatoes can fall to the ground from the gaps between the conveying circular plates 3. The cleaning operation of the soil adhered to the surface of the potatoes can be carried out while conveying the potatoes, making the surface of the harvested potatoes cleaner.

[0026] In another embodiment provided by the present utility model, the connection lines between the conveying rollers 2 on the conveying seat 1 are straight lines on both sides and a conveying line with a convex portion protruding towards the top of the conveying seat 1 in the middle, that is, the conveying rollers 2 on both sides of the conveying seat 1 are horizontally arranged, and the conveying rollers 2 in the middle of the conveying seat 1 are convexly arranged towards the top side thereof; three auxiliary rollers 8 are rotatably installed on the side wall of the conveying seat 1, and the three auxiliary rollers 8 are respectively located at three bending positions formed by connecting the conveying rollers 2, and the three auxiliary rollers 8 are all pressed against the outer wall of the synchronous belt 6.

[0027] Specifically, the three auxiliary rollers 8 are respectively located at three bending positions formed by connecting the conveying rollers 2, and there are also three corresponding bending positions on the synchronous belt 6, that is, the two bending positions at the connection parts of the two straight lines and the convex portion and the bending position of the convex portion. The bending position at the connection of the straight line and the convex portion is the first bending surface 9, and the bending position of the convex portion is the second bending surface 10. When the conveying roller 2 and the conveying circular plate 3 perform the conveying operation on the potatoes, since the connection lines between the conveying rollers 2 on the conveying seat 1 are straight lines on both sides and a conveying line with a convex portion protruding towards the top of the conveying seat 1 in the middle, the potatoes roll at the position of the first bending surface 9 corresponding to the conveying roller 2 and the conveying circular plate 3, making the rolling of the potatoes faster. When the potatoes move to the position of the second bending surface 10 on the conveying roller 2 and the conveying circular plate 3, the potatoes roll from the top of the second bending surface 10 to the bottom thereof, so that the potatoes can roll from the top (i.e., the high place) of the second bending surface 10 to the bottom (i.e., the low place) of the second bending surface 10, making the potatoes roll faster and enabling a comprehensive cleaning operation of the remaining soil on the potatoes, making the surface of the harvested potatoes cleaner. At the same time, the auxiliary rollers 8 are pressed against the outer wall of the synchronous belt 6, enabling a stable transmission operation between the synchronous belt 6 and the synchronous pulley 5 and preventing the phenomenon of the synchronous pulley 5 idling.

[0028] In another embodiment provided by the present utility model, two symmetrically arranged driving rollers 11 are rotatably installed on the conveying seat 1, and the two driving rollers 11 are connected by a transmission belt 16; a plurality of pushing plates 12 are evenly installed on the transmission belt 16, and each of the pushing plates 12 abuts against the top end of the conveying circular plate 3; each of the pushing plates 12 and the transmission belt 16 are connected by a triangular plate 13; one of the driving rollers 11 penetrates through the conveying seat 1 and is connected with a driven gear 14, and a driving gear 15 is installed on one of the synchronous wheels 5, and the driving gear 15 and the driven gear 14 are meshed with each other.

[0029] Specifically, when the driving member 7 drives the conveying roller 2 and the conveying circular plate 3 to rotate through the synchronous wheel 5 and the synchronous belt 6, the synchronous wheel 5 drives the driving gear 15 to rotate clockwise. Since the driving gear 15 and the driven gear 14 are meshed with each other, the driving gear 15 drives the driven gear 14 to rotate counterclockwise, and the driven gear 14 drives the driving roller 11 connected thereto to rotate counterclockwise. Since the two driving rollers 11 are driven by the transmission belt 16, the driving roller 11 drives the transmission belt 16 to rotate, and the transmission belt 16 drives the pushing plate 12 to rotate, so that the pushing plate 12 can push the potatoes on the conveying circular plate 3 to move, so that the potatoes can smoothly roll through the convex portions of the conveying roller 2 and the conveying circular plate 3, so that the potatoes will not accumulate at the position of the first bending surface 9 corresponding to the conveying roller 2 and the conveying circular plate 3, and stable conveying operation of the potatoes can be carried out, improving the conveying efficiency of the potatoes.

[0030] Only some exemplary embodiments of the present utility model are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present utility model, the described embodiments can be modified in various different ways. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present utility model.
