Referring to fig. 1 to 6, the present embodiment provides a chain rake type conveying structure for a potato harvester, including two side plates 1, a driving shaft 10 rotatably disposed at a rear end portion between the two side plates 1, a driven shaft 11 rotatably disposed between the two side plates 1, in order to facilitate conveying of potatoes harvested by the potato harvester, a first gear 12 is fixedly disposed at end portions of the driving shaft 10 and the driven shaft 11, a chain rake structure 2 is driven on the first gear 12, the chain rake structure 2 includes a driving chain 20 and a plurality of first rake bars 21 disposed between the two driving chains 20, in order to facilitate use by people, the plurality of first rake bars 21 include a rotating bar 210, a housing 22 is rotatably disposed on an outer wall of the rotating bar 210, in order to enable harvested potatoes to pass through the chain rake structure 2, a cleanliness degree of a surface of the potatoes and ensure efficiency of conveying of the potatoes are ensured, a brush bar 211 is fixed on the rotating bar 210, in order to ensure efficiency of brushing the brush bar 211 on the first rake bar 21, a second brush bar 230 is disposed at a position below the rotating bar 230, and a second rack bar 230 is connected to facilitate the potato conveying, and a second rack bar 230 is connected to the rotating bar 230.

Preferably: the brush on the outer wall of the brush rod 211 is made of rubber.

The working process comprises the following steps: the two driving chains 20 are driven to rotate by rotating the driving shaft 10 and the driven shaft 11 is driven to rotate, meanwhile, the first rake rods 21 rotate around the first gear 12 along with the driving chains 20 to convey harvested potatoes, when the first rake rods 21 rotate to the upper part of the first gear 12, the second gear 23 at the right end of the rotating rod 210 is meshed with the rack 230, at the moment, the first rake rods 21 start to rotate, the surfaces of the potatoes on the chain rake structures 2 are brushed, silt attached to the surfaces of the potatoes is cleaned up, and the first rake rods 21 rotate to have a certain driving force on the potatoes, so that the potato conveying efficiency can be improved, and the first rake rods 21 can be prevented from rotating by the outer cover 22 and are pushed to the lower parts of the first rake rods 21.

From the above, further describing the connection mode of the chain harrow structure 2 and the side plate 1, the rack 230 on the right side is movably matched with the two first gears 12 on the same side of the side plate 1 on the right side, and the rack 230 on the left side is movably matched with the two first gears 12 on the same side of the side plate 1 on the left side.

Furthermore, in order to enhance the stability of the chain harrow structure 2 in conveying potatoes and prevent soil caves from falling, the second harrow bars 24 are arranged among the first harrow bars 21 in a staggered manner, the second harrow bars 24 can only rotate along with the rotation of the transmission chain 20, the second harrow bars 24 cannot rotate, and the second harrow bars 24 are matched with the outer cover 22, so that the stability of the chain harrow structure 2 in conveying potatoes can be ensured, and the soil caves are prevented from falling to the lower parts of the first harrow bars 21.

By the above-mentioned, when unfortunately using, can rotate dustcoat 22 and cover brush-holder stud 211 is whole, the position that needs to go on the dustcoat 22 this moment limits, the fixed boss 220 that is equipped with of dustcoat 22 left end, the boss 220 outer wall is located the upper surface and has seted up screw hole 221, be close to the bull stick 210 left end and seted up spacing hole 212, spacing hole 212 passes through bolted connection with screw hole 221, use the bolt to twist screw hole 221 and insert in spacing hole 212, can guarantee that dustcoat 22 is stable covers brush-holder stud 211, prevent that dustcoat 22 from removing.

Furthermore, in order to facilitate people to determine the direction of the outer cover 22, the limiting hole 212 penetrates through the rotating rod 210, the direction of the opening of the limiting hole 212 points to the middle of the top of the brush rod 211, so that people can conveniently cover the direction of the brush rod 211 when the outer cover 22 rotates, and the outer cover 22 can be directly rotated by 180 degrees.

It should be noted that, the average size of the potatoes is different because the potatoes are influenced by soil nutrients, so as to facilitate the adjustment of the distance between the first rake lever 21 and the second rake lever 24 according to the needs of people and prevent the potatoes from falling off when being transported on the chain rake structure 2, the outer diameter of the first rake lever 21 is the same as that of the second rake lever 24, the diameter of the outer cover 22 is larger than that of the second rake lever 24, the outer cover 22 is rotated to cover the brush bar 211, the outer diameter of the first rake lever 21 can be increased, and the distance between the first rake lever 21 and the second rake lever 24 can be reduced.

Moreover, in order to ensure the reasonability of the structure, the brush rod 211 is of a half brush and a half smooth structure, the brush surface of the brush rod 211 leaks out of the outer cover 22, so that silt on the surface of the potatoes can be cleaned when the chain harrow structure 2 conveys the potatoes, and when the smooth surface of the brush rod 211 leaks out of the outer cover 22, the chain harrow structure 2 can be used for conveying the potatoes.

When the chain-rake conveying structure for the potato harvester of the embodiment is used specifically, the harvested potatoes are conveyed by rotating the first rake rods 21 around the first gear 12 along with the transmission chain 20, and when the first rake rods 21 rotate to the upper part of the first gear 12, the second gear 23 at the right end of the rotating rod 210 is meshed with the rack 230, at this time, the first rake rods 21 start to rotate and brush the surfaces of the potatoes on the chain-rake structure 2, so that silt attached to the surfaces of the potatoes is cleaned, the surfaces of the harvested potatoes are cleaned, and the cleanliness of the potatoes is ensured;

and, first harrow pole 21 rotates and has certain driving force to the potato, can improve the efficiency that the potato was carried, and first harrow pole 21 can be prevented to the dustcoat 22 from rotating, pushes away the potato to first harrow pole 21 lower part, rotates dustcoat 22 and covers brush-holder stud 211, can increase first harrow pole 21's external diameter, can reduce the interval between first harrow pole 21 and the second harrow pole 24 simultaneously, is convenient for adjust the interval according to people's needs.

The foregoing shows and describes the basic principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the description in the above embodiments and the description is only the preferred embodiments of the present invention, and is not intended to limit the present invention, and that there may be various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications all fall within the scope of the present invention as claimed.
