Description

Technical Field

[0001] The utility model relates to the field of corn processing, in particular to a corn peeling device. Background Art

[0002] After corn is harvested, the husk needs to be peeled off. Currently, there is an automated corn peeling device such as a corn peeling machine disclosed in the patent document with publication number CN111631006A. This solution uses the protrusions on the peeling roller to remove the corn husk. There are some problems when using this solution. After the protrusions in this solution peel off the corn husk, it is likely that the corn husk is not easily separated from the protrusions, resulting in the protrusions being unable to fully pierce and hook the subsequent corn husk, thereby affecting the subsequent corn peeling efficiency. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a corn peeling device, which can efficiently and fully remove corn husks and prevent corn husks from accumulating on the protrusions of the peeling roller.

[0004] The utility model solves the technical problem by adopting the following technical solution: a corn peeling device, comprising a hopper and a conveying line arranged on a frame;

[0005] The discharge port of the hopper is connected to the upstream end of the conveyor line;

[0006] A plurality of parallel feed roller groups are arranged along the conveying line, and the feed roller group includes a peeling roller and a transmission roller, and the peeling roller and the transmission roller rotate in a relative direction;

[0007] The peeling roller is provided with a plurality of groups of protrusions; the same group of protrusions are distributed around the outer circumference of the peeling roller, and annular grooves are provided between adjacent groups of protrusions;

[0008] The frame is provided with a peeling support rod, the peeling support rod is located on the outside of the conveying line, the peeling support rod extends into the annular groove, and a gap is left between the peeling support rod and the side wall of the annular groove.

[0009] In this scheme, corn enters the conveyor line from the hopper downward. In the process of moving the corn from the upstream end to the downstream end on the conveyor line, the peeling roller and the transmission roller rotate relative to each other, and the corn husk will be peeled off by the peeling roller. The corn husk is hooked on the protrusion of the peeling roller. Since an annular groove extended by the peeling support rod is provided between the protrusions of adjacent groups, the peeling roller moves relative to the peeling support rod during rotation. Therefore, the peeling support rod will make the corn husk hooked on the protrusion separate from the peeling roller, so as to avoid the corn husk affecting the peeling effect of the subsequent peeling roller.

[0010] Preferably, the feed roller set includes several sets, and each set of the feed roller set forms a groove-shaped conveying line to ensure that the corn will not move to the outside when the conveying line moves.

[0011] Preferably, the upstream end of the conveyor line is higher than the downstream end, so as to facilitate the movement of corn to the downstream end.

[0012] Preferably, the transmission rollers in the same group of the feeding rollers are located below the peeling rollers. Under the action of gravity, the corn is more likely to contact the transmission rollers downwards to ensure that it can be continuously powered to be transported to the downstream end.

[0013] Preferably, the outer circumference of the transmission roller is provided with a spiral protrusion, so that the spiral protrusion can be used to rotate and transport the corn, and can provide power for the movement of the corn.

[0014] Preferably, the peripheral linear speed of the rotation speed of the transmission roller is smaller than the peripheral linear speed of the peeling roller, so as to form a rotation linear speed difference, provide resistance for the rotation of the corn, and facilitate the removal of the corn skin.

[0015] Preferably, the peeling support rod is radially fixed to the rotating shaft, and the rotating shaft is driven by a motor. The peeling support rod is driven by the rotating shaft to rotate to remove the protruding corn husks. The rotating shaft will provide centrifugal force to the peeling support rod, so that the corn husks are thrown out of the peeling support rod to prevent the corn husks from accumulating on the peeling support rod. Since the peeling support rod is outside the conveyor line, the corn husks can be prevented from being mixed with the corn again.

[0016] Preferably, the rotating shaft and the peeling roller rotate in opposite directions, and the speed difference between the rotating shaft and the peeling roller is 5-10%. The rotating shaft rotates together to avoid too large a speed difference between the two, which causes the peeling support rod to cut off the corn husk in contact from the annular groove. The speed difference can separate the two, and avoid providing sufficient centrifugal force to throw the corn husk off the peeling support rod.

[0017] Preferably, the lower end of the hopper is connected to the discharge port through an inclined spreading trough, and a vibrator is provided on the back of the spreading trough. The corn can be fully spread out when it enters the discharge port through the spreading trough, and the vibrator can further spread it quickly to reduce accumulation, so that it can fully contact with the feeding roller group later.

[0018] Preferably, a baffle is arranged above the paving trough, and the distance between the lower side of the baffle and the bottom of the paving trough is greater than the diameter of one corn and smaller than the diameter of two corns. The baffle can push down the accumulated corn to avoid corn accumulation.

[0020] This solution can efficiently and fully remove corn husks and can prevent corn husks from accumulating on the protrusions of the peeling roller, and is very convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. The embodiments are only used to explain the present invention and do not limit the protection scope of the present invention.

[0027] Example

[0028] like Figure 1 As shown, a corn peeling device comprises a hopper 6 and a conveying line arranged on a frame; the discharge port of the hopper 6 is connected to the upstream end of the conveying line; a plurality of parallel feed roller groups 10 are arranged along the conveying line, the feed roller group 10 comprises a peeling roller 2 and a conveying roller 1, and the peeling roller 2 and the conveying roller 1 rotate in a relative direction; the peeling roller 2 is provided with a plurality of groups of protrusions 5; the same group of protrusions 5 are distributed around the outer circumference of the peeling roller 2, and an annular groove 11 is provided between adjacent groups of the protrusions 5;

[0029] Combination Figure 2 As shown, the frame is provided with a peeling support rod 4, and the peeling support rod 4 is located on the outside of the conveying line. The peeling support rod 4 extends into the annular groove 11, and a gap is left between the peeling support rod 4 and the side wall of the annular groove 11.

[0030] In this scheme, corn enters downward from the hopper 6 to the conveyor line. In the process of the corn moving from the upstream end to the downstream end of the conveyor line, the peeling roller 2 and the transmission roller 1 rotate relative to each other, and the corn husk will be peeled off by the peeling roller 2, and the corn husk will be hooked on the protrusion 5 of the peeling roller 2. Since an annular groove 11 extended by the peeling support rod 4 is provided between adjacent groups of protrusions 5, the peeling roller 2 moves relative to the peeling support rod 4 during rotation. Therefore, the peeling support rod 4 will make the corn husk hooked on the protrusion 5 separate from the peeling roller 2, so as to prevent the corn husk from affecting the peeling effect of the subsequent peeling roller 2.

[0031] The feeding roller set 10 includes several sets, and each set of the feeding roller set 10 forms a groove-shaped conveying line to ensure that the corn will not move to the outside when the conveying line moves.

[0032] The upstream end of the conveyor line is higher than the downstream end, so that the corn can be easily moved to the downstream end.

[0033] The transmission roller 1 in the same group of the feeding roller group 10 is located below the peeling roller 2. Under the action of gravity, the corn is more likely to contact the transmission roller 1 downward to ensure that it can be continuously powered to be transported to the downstream end.

[0034] The outer circumference of the transmission roller 1 is provided with a spiral protrusion 5. The spiral protrusion 5 is used to rotate and transport the corn, which can provide power for the movement of the corn.

[0035] The peripheral linear speed of the rotation speed of the transmission roller 1 is less than the peripheral linear speed of the peeling roller 2, so as to form a rotation linear speed difference, provide resistance for the rotation of the corn, and facilitate the removal of the corn skin.

[0036] The peeling support rod 4 is radially fixed to the rotating shaft 3, and the rotating shaft 3 is driven by a motor. The peeling support rod 4 is driven by the rotating shaft 3 to rotate, and the corn husk on the protrusion 5 is removed. The rotating shaft 3 will provide centrifugal force to the peeling support rod 4, so that the corn husk is thrown out from the peeling support rod 4, and the corn husk is prevented from accumulating on the peeling support rod 4. Since the peeling support rod 4 is outside the conveying line, the corn husk can be prevented from being mixed with the corn again.

[0037] The rotating shaft 3 rotates in opposite directions with the peeling roller 2, and the speed difference between the rotating shaft 3 and the peeling roller 2 is 5-10%. The rotating shaft 3 rotates together to avoid too large a speed difference between the two, which causes the peeling support rod 4 to cut off the corn husk in contact from the annular groove 11. The speed difference can separate the two, and avoid providing sufficient centrifugal force to throw the corn husk off the peeling support rod 4.

[0038] Combination Figure 3As shown, the lower end of the hopper 6 is connected to the discharge port through an inclined spreading trough 7, and a vibrator 8 is provided on the back of the spreading trough 7. The corn can be fully spread when it enters the discharge port through the spreading trough 7, and the vibrator 8 can further spread it quickly to reduce accumulation, so that it can fully contact with the feeding roller group 10 later.

[0039] A baffle plate 9 is arranged above the material laying trough 7, and the distance between the lower side of the baffle plate 9 and the bottom of the material laying trough 7 is greater than the diameter of one corn and less than the diameter of two corns. The baffle plate 9 can push down the accumulated corns to avoid corn accumulation. The diameter of the corn here is determined according to the average diameter of most corns that need to be peeled.

[0040] This solution can efficiently and fully remove corn husks and can prevent corn husks from accumulating on the protrusions 5 of the peeling roller 2, and is very convenient to use.

[0041] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
