Description

Technical Field

[0001] The present invention relates to the technical field of agricultural product processing, and more particularly to a fresh corn cob sorting device for replacing manual directional placement and sorting in front of a corn peeling machine or a corn cob head and tail removing machine. Background Art

[0002] Fresh corn refers to a special variety of corn harvested during the milky or waxy stage. It can be used as grain, fruit, and vegetable. It is a high-quality ready-to-eat food that is deeply loved by consumers. Its consumption has been steadily increasing, and it has good market prospects and high economic value.

[0003] Fresh corn production is highly seasonal, with a short processing window. Processing must be completed promptly after harvest to maintain freshness, taste, and nutritional quality. Currently, the early production process for fresh corn ears utilizes a combination of manual orientation and mechanized peeling. In one approach, the ears are manually fed into a peeling machine for peeling. After peeling, the corn is manually reoriented and fed into a head and tail remover, where the machine removes the seedless ends and thick roots. In another approach, the ears are manually reoriented and fed into a tail remover for tail removal. The tail-cut ears are then fed into a peeling machine for peeling. Reorientation is a common and crucial auxiliary operation in corn processing. Peeling, head and tail removal, and whole-ear packaging all require the corn to be oriented. In practice, a fresh corn production line with a production capacity of 10,000 ears per hour requires over 10 workers simply for the process of arranging the corn. This manual operation is inefficient and costly, making it unsuitable for industrialized, efficient production. Summary of the Invention

[0043] The technical solutions of the present invention will be described clearly and completely below with reference to the accompanying drawings. It is obvious that the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0044] like Figures 1 to 5The present invention provides a fresh corn cob sorting device, the device includes a frame 6 and a clamping conveyor belt 1 and a horizontal conveyor belt 2 fixedly connected to the frame 6, the clamping conveyor belt 1 is used to clamp the corn cobs 7 and convey them forward, and is located just above the horizontal conveyor belt 2. Preferably, the clamping conveyor belt 1 adopts a belt with a circular cross-section; along the conveying direction of the clamping conveyor belt 1, the clamping spacing formed by the clamping conveyor belt 1 gradually increases, and the distance between the horizontal conveyor belt 2 and the clamping conveyor belt 1 gradually increases. At the discharge end near the horizontal conveyor belt 2, the clamping spacing a formed by the clamping conveyor belt 1 is greater than the maximum diameter of the corn cob, and the corn cob will completely break away from the clamping conveyor belt at the rear end of the clamping conveyor belt 1; the horizontal conveyor belt 2 is consistent with the conveying direction of the clamping conveyor belt 1, and the conveying speed of the horizontal conveyor belt 2 is greater than the conveying speed of the clamping conveyor belt 1. Before the corn cob breaks away from the clamping effect of the clamping conveyor belt 1, the horizontal conveyor belt 2 drives the head of the corn cob to be conveyed, and transforms the clamping conveying with the head of the corn cob tilted backward into the clamping conveying with the head tilted forward. The horizontal conveyor belt 2 used here always supports the heads of the corn ears when the corn ears are in a clamped state and are tilted, and gradually changes the direction of the heads of the corn ears with their heads facing backwards. Then, in the rear section of the conveying of the horizontal conveyor belt 2, the corn ears are reversed, and the heads of all corn ears are facing the conveying direction (i.e., the heads are ahead), without the need for manual placement, which can greatly reduce labor costs.

[0045] The horizontal conveyor belt 2 includes an endless flat belt 21 and a plurality of lifting brackets 22. The endless flat belt 21 forms an endless conveyor on the vertical plane. The plurality of lifting brackets 22 are supported on the lower end of the endless flat belt 21 along the length direction of the endless flat belt 21. Each lifting bracket 22 is adjustable up and down to adjust the drop distance between the upper end surface of the endless flat belt 21 and the clamping conveyor belt 1. It can be adjusted according to the length of the corn cob and is suitable for sorting fresh corn cobs of different varieties and sizes.

[0046] like Figure 5As shown, the lifting bracket 22 includes a telescopic rod 221 and a support sleeve 222. Each lifting bracket 22 includes two parallel telescopic rods 221 and two parallel support sleeves 222. The lower ends of the two support sleeves 222 are fixed to the frame 6, and the lower parts of the telescopic rods 221 are correspondingly sleeved in the support sleeves 222. An upper support block 224 is fixed between the two telescopic rods 221, that is, the two are fixedly connected through the upper support block 224. The two supporting sleeves 222 are fixedly connected by a lower supporting block 223. A wire sleeve 226 is fixed in the middle of the lower supporting block 223. The wire sleeve 226 has an internal threaded hole. A wire rod 225 passes through the wire sleeve 226. The wire rod 225 and the wire sleeve 226 form a threaded connection. The upper end of the wire rod 225 forms a relative rotation connection with the shaft sleeve 228 fixed on the upper supporting block 224. A rotating handle 227 is also fixed on the wire rod 225 for driving the wire rod 225 to rotate. The wire rod 225 is driven to rotate by manually driving the rotating handle 227. Since the position of the wire sleeve 226 is fixed, the forward and reverse rotation of the wire rod 225 can be controlled to realize the lifting and lowering of the wire rod 225, thereby promoting the lifting and lowering of the upper supporting block and the telescopic rod, thereby achieving the purpose of lifting and lowering the annular flat belt.

[0047] In order to facilitate the lifting and lowering of different positions of the endless flat belt 21, the present invention arranges the endless flat belt 21 into multiple sections, and two adjacent sections of the endless flat belt 21 are flexibly connected, and each section of the endless flat belt 21 is independently provided with a lifting bracket 22 that can be adjusted up and down. Along the conveying direction of the horizontal conveyor belt 2, the multiple sections of the endless flat belt 21 are distributed in a downward step, that is, in the conveying direction, the height of each section of the endless flat belt 21 gradually decreases.

[0048] like Figure 2 and 3 As shown, the present invention is further preferably provided with three sections along the conveying direction, namely the first section horizontal conveyor belt 2a, the second section horizontal conveyor belt 2b and the third section horizontal conveyor belt 2c, and the conveying height is successively reduced, the discharge end of the first section horizontal conveyor belt 2a is connected to the feed end of the second section horizontal conveyor belt 2b by angle adjustment plates 9 on both sides, and the discharge end of the second section horizontal conveyor belt 2a is connected to the feed end of the third section horizontal conveyor belt 2c by angle adjustment plates on both sides to form a height-adjustable connection. After the corn ears 7 are conveyed by the second section horizontal conveyor belt 2b, the heads of all the corn ears are tilted forward, and then conveyed by the third section horizontal conveyor belt 2c, so that the corn ears 7 are completely separated from the clamping conveyor belt 1 for output. The horizontal conveyor belt used here preferably adopts a whole endless belt structure, and the height of each conveying surface is adjusted by a lifting bracket.

[0049] like Figure 2 、 Figure 3 and Figure 6As shown, the clamping conveyor belt 1 used includes a first circular conveyor belt 11 and a second circular conveyor belt 12 which are arranged in parallel on the same horizontal plane. The two are arranged left and right along the conveying direction. A clamping distance a which gradually increases along the conveying direction is formed between the first circular conveyor belt 11 and the second circular conveyor belt 12. The first circular conveyor belt 11 and the second circular conveyor belt 12 convey in the same direction and have the same conveying speed.

[0050] In order to achieve a better clamping and conveying effect for corn ears, the first circular conveyor 11 located on one side of the clamping conveyor belt 1 is provided with multiple sections of circular conveyor belts I11a connected in series, and a drive connection is formed between the two adjacent sections of the circular conveyor belts I11a through a pulley 3; the second circular conveyor belt 12 located on the other side of the clamping conveyor belt 1 is provided with multiple sections of circular conveyor belts II12a connected in series, and a drive connection is formed between the two adjacent sections of the circular conveyor belts II12a through a pulley 3, the number of sections of the circular conveyor belt I11a is the same as the number of sections of the circular conveyor belt II12a, and each section of the circular conveyor belt I11a forms a one-to-one corresponding clamping distance a with each section of the circular conveyor belt II12a, and the clamping distance a is used to clamp corn ears.

[0051] like Figure 3 As shown, the annular conveyor belt I and the annular conveyor belt II each include three sections, forming three sections of clamping distance a connected in series. The horizontal conveyor belt 2 located below them is also provided with three sections, and the conveying length of each section of the horizontal conveyor belt 2 is consistent with the length of each section of the clamping distance a.

[0052] The pulleys 3 at both ends of each section of the endless conveyor belt I and the pulleys 3 at both ends of each section of the endless conveyor belt II are respectively installed on linear slide rails 4 for adjusting the clamping distance a. Figure 1 Among the pulleys, a short belt is connected between the pulleys 3 of the two rear sections of the endless conveyor belt I, and a short belt is connected between the pulleys 3 of the two rear sections of the endless conveyor belt II, so that the two sections of the endless conveyor belt I and the two sections of the endless conveyor belt II are located at the same level, which makes it easier to achieve a stable transition of corn ears from one endless conveyor belt to another.

[0053] The present invention arranges multiple sections of annular conveyor belts and multiple sections of horizontal conveyor belts to form a clamping structure on the same horizontal plane, and adjusts the height difference between the clamping position and the horizontal conveyor belt below through a lifting bracket. The forward conveying speed of the horizontal conveyor belt is faster than the forward conveying speed of the clamping conveyor belt, so that the corn ears with their heads facing backwards are quickly adjusted to a state with their heads facing forwards, and the automatic reversal of the corn ears is quickly completed. The purpose of all the corn ears with their heads facing the same direction can be achieved without manual placement, and the application of the present invention in peeling machines and head and tail cutting machines will play an important role.

[0054] Any matters not described in the present invention are applicable to the prior art.

[0055] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
