Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of agricultural product processing and conveying equipment, and specifically relates to a corn cob sorting device. Background Technology
[0002] On a corn processing production line, the initial feeding and sorting process of corn cobs directly affects the processing efficiency and product consistency of subsequent cutting, packaging, and other stages. Currently, the industry mainly uses manual feeding or semi-automatic equipment to complete this process.
[0003] In manual processing, operators manually arrange loose corn cobs and feed them into the conveyor line. This method is labor-intensive, with a single person typically processing no more than 500 cobs per hour, making it difficult to match the pace of automated production lines. Furthermore, the spacing error in manual arrangement generally exceeds ±15mm, easily causing bottlenecks in subsequent processes, and human contact can easily damage the surface of the fresh corn.
[0004] Semi-automatic material handling equipment typically uses a single or two-section conveyor combined with a fixed baffle structure. For example, in existing solutions, the conveyor runs continuously without load and lacks a control mechanism that automatically starts and stops based on the material status, resulting in high energy consumption; the discharge end is limited only by a simple baffle and lacks a mechanism to achieve equidistant arrangement, so the spacing error of the corn cobs output is generally more than 10mm.
[0005] In summary, the existing corn cob feeding process suffers from poor discharge uniformity, and there is an urgent need for a corn cob feeding device that can effectively control the spacing between corn cobs. Utility Model Content
[0006] The main purpose of this utility model is to provide a corn cob sorting device, which aims to solve the technical problem of poor discharge uniformity in the corn cob sorting process in the prior art.
[0007] In order to achieve the above-mentioned utility model objectives, this utility model proposes a corn cob sorting device, including a frame and a first set of sorting and conveying mechanisms disposed on the frame; The first set of material handling and conveying mechanisms includes a front conveying mechanism, a rear conveying mechanism, a blocking mechanism, and an in-situ detection mechanism; The output port of the front conveying mechanism is configured to correspond to the input port of the rear conveying mechanism; The in-situ detection mechanism is provided in relation to the downstream conveying mechanism and is used to detect the in-situ status of the corn cobs in the downstream conveying mechanism. The blocking mechanism is disposed between the output end of the front conveying mechanism and the input end of the rear conveying mechanism, and is used to block or allow the corn cobs on the front conveying mechanism to be conveyed to the rear conveying mechanism according to the presence of the corn cobs. The downstream conveying mechanism includes a first sub-conveyor mechanism and a second sub-conveyor mechanism; The output end of the first sub-conveying mechanism is configured to correspond to the input end of the second sub-conveying mechanism; The in-situ detection mechanism detects the in-situ status of corn cobs on the first sub-conveying mechanism and the second sub-conveying mechanism, respectively.
[0008] Furthermore, the corn cob feeding device also includes a second feeding conveying mechanism that is the same as the first feeding conveying mechanism and is mounted on the frame; The first set of material handling and conveying mechanisms and the second set of material handling and conveying mechanisms are symmetrically arranged based on a baffle fixed on the frame.
[0009] Furthermore, the corn cob handling device also includes a material distribution mechanism; the material distribution mechanism includes a support frame, and a conveyor belt, side guards, and partitions disposed on the support frame; The guardrail includes two sections, which are respectively disposed on both sides of the conveyor belt; The partition is suspended above the conveyor belt and cooperates with the two side guards to form two limiting grooves; The output ports of the two limiting slots are respectively set to correspond to the input ports of the front conveying mechanisms of the first set of material handling conveying mechanisms and the second set of material handling conveying mechanisms.
[0010] Furthermore, the corn cob feeding device also includes a first gantry frame, which is mounted on the frame; The blocking mechanism includes a driver and a blocking plate; The driver is mounted on the first gantry, and the blocking plate is mounted on the output end of the driver.
[0011] Furthermore, the blocking plate is hinged to the baffle; The output end of the driver is hinged to the blocking plate.
[0012] Furthermore, the corn cob handling device also includes a feeding chute, which is fixed relative to the frame and located below the front conveying mechanism and the rear conveying mechanism, for collecting corn cobs that fall from the front conveying mechanism and the rear conveying mechanism.
[0013] Furthermore, the corn cob feeding device also includes a second gantry frame, on which the first drive motor of the first sub-conveyor mechanism is mounted.
[0014] Furthermore, a second drive motor for the second sub-conveyor is provided at the end of the frame away from the first sub-conveyor.
[0015] Furthermore, the in-situ detection mechanism includes a first sub-position detection mechanism and a second sub-position detection mechanism, which are respectively set up corresponding to the first sub-conveying mechanism and the second sub-conveying mechanism.
[0016] Beneficial effects: This utility model discloses a corn cob feeding device. It comprises a front conveying mechanism and a rear conveying mechanism mounted on a frame, with a blocking mechanism positioned between the output end of the front conveying mechanism and the input end of the rear conveying mechanism. Simultaneously, a position detection mechanism is positioned at a corresponding location on the rear conveying mechanism. This allows the blocking mechanism to automatically block or allow corn cobs from being conveyed from the front conveying mechanism to the rear conveying mechanism based on their position on the rear conveying mechanism. Compared with existing technologies, this device offers the following advantages: 1. When there are corn cobs on the downstream conveyor, the blocking mechanism stops the upstream conveyor from continuing to feed, preventing material accumulation on the downstream conveyor. When there are no corn cobs on the downstream conveyor, the blocking mechanism moves aside, and the upstream conveyor replenishes corn cobs promptly. This achieves an intermittent feeding mode of "stopping when there is material and replenishing when there is no material," ensuring that the downstream conveyor always maintains a single (or a set number) buffer state, thereby significantly improving the uniformity of corn cob output and meeting the precise feeding requirements of subsequent automated processing. When two or more sub-segments are set, the buffer depth increases, further improving the uniformity of the output spacing.
[0017] 2. The front-end conveying mechanism does not need to be frequently started and stopped. Only the blocking mechanism performs intermittent blocking and stopping actions, which reduces the mechanical loss and power consumption of the conveying motor caused by repeated starting and stopping, and extends the service life of the equipment.
[0018] 3. It can adopt simple control logic (the in-situ detection mechanism is only used to trigger the blocking mechanism), and has high stability and reliability in the humid and dusty corn processing environment.
[0019] 4. By adjusting the timing of the blocking mechanism, it can be adapted to corn cobs of different diameters (30-80mm) and lengths (150-400mm), making it highly versatile and adaptable to various material feeding needs without the need to replace parts. Attached Figure Description

[0027] Reference Figure 1 This utility model provides a corn cob sorting device, including a frame 101 and a first set of sorting and conveying mechanisms disposed on the frame 101. The first set of sorting and conveying mechanisms includes a front conveying mechanism 102, a rear conveying mechanism 103, a blocking mechanism 104, and an on-site detection mechanism. The output port of the front conveying mechanism 102 is correspondingly configured with the input port of the rear conveying mechanism 103, so that corn cobs can be transferred from the front conveying mechanism 102 to the rear conveying mechanism 103. The on-site detection mechanism is configured corresponding to the rear conveying mechanism 103 and is used to detect whether there are corn cobs on the rear conveying mechanism 103 (i.e., on-site status). The blocking mechanism 104 is disposed between the output end of the front conveying mechanism 102 and the input end of the rear conveying mechanism 103, and is used to selectively block or allow corn cobs on the front conveying mechanism 102 to be conveyed to the rear conveying mechanism 103 according to the on-site status of corn cobs detected by the on-site detection mechanism.
[0028] In this embodiment, both the front conveyor mechanism 102 and the rear conveyor mechanism 103 are belt conveyors, each driven by an independent motor. The in-situ detection mechanism preferably uses a photoelectric sensor (not shown), installed at or above the feed end of the rear conveyor mechanism 103, and its detection signal is output to a controller (such as a PLC, not shown). The blocking mechanism 104 can be a cylinder-driven baffle or baffle structure. Its operation is as follows: When there are no corn cobs on the rear conveyor mechanism 103, the in-situ detection mechanism outputs an "empty" signal, the controller puts the blocking mechanism 104 in a yielding state, the front conveyor mechanism 102 runs and feeds the corn cobs into the rear conveyor mechanism 103; when there are corn cobs on the rear conveyor mechanism 103 (i.e., material is detected), the in-situ detection mechanism outputs a "material present" signal, the controller triggers the blocking mechanism 104 to block the corn cobs at the output end of the front conveyor mechanism 102, suspending material supply to the rear conveyor until the corn cobs on the rear conveyor mechanism 103 are conveyed away and the system returns to an empty state. This cycle ensures that the downstream conveyor mechanism 103 always maintains a single-buffer mode of "stopping supply when there is material and replenishing when there is no material".
[0029] In this embodiment, by installing a position detection mechanism on the rear conveying mechanism 103 and using the blocking mechanism 104 at the front output end as the actuating component, the number of corn cobs on the rear conveying mechanism 103 is always no more than one (or a set number), thus avoiding the stacking and compression of multiple corn cobs. The rear conveying mechanism 103 acts as a buffer zone, and its output end can continuously output corn cobs with uniform spacing, significantly improving the equidistant discharge and providing a stable material flow for subsequent cutting, packaging, and other processes. Simultaneously, the front conveying mechanism 102 does not require frequent start-stop operations, reducing motor wear.
[0030] In one embodiment, the corn cob feeding device further includes a second feeding conveyor mechanism that is the same as the first feeding conveyor mechanism and is mounted on the frame 101; the first feeding conveyor mechanism and the second feeding conveyor mechanism are symmetrically arranged based on a baffle 105 fixed on the frame 101.
[0031] A baffle 105 is vertically installed in the middle of the frame 101 along the conveying direction, dividing the space on the frame 101 into two symmetrical areas. The first set of material handling and conveying mechanisms is located on one side of the baffle 105, and the second set is located on the other side. The two sets of mechanisms have identical structures and operate independently. Each set has its own front conveying mechanism, rear conveying mechanism, blocking mechanism, and in-situ detection mechanism. The two sets are separated by the baffle 105 to prevent corn cobs from slipping during conveying. Incoming material from upstream is fed into the front input ends of the two sets of material handling and conveying mechanisms via a material distribution mechanism (see subsequent embodiments).
[0032] In this embodiment, two sets of symmetrical material handling and conveying mechanisms are set up, which doubles the material handling efficiency of the entire production line while maintaining the independent control capability of each set. When one set requires maintenance or fails, the other set can continue to operate, improving the redundancy and reliability of the production line. The baffle 105 is set to avoid interference between the corn cobs and the two channels, ensuring the stability of each set of material handling.
[0033] In one embodiment, the corn cob sorting device further includes a sorting mechanism; the sorting mechanism includes a support 106, and a conveyor belt 107, side rails 108, and partitions 109 disposed on the support 106; the side rails 108 include two, respectively disposed on both sides of the conveyor belt 107; the partitions 109 are suspended above the conveyor belt 107, and respectively cooperate with the two side rails 108 to form two limiting grooves; the output ports of the two limiting grooves are respectively disposed corresponding to the input ports of the front conveying mechanism 102 of the first set of sorting conveying mechanism and the second set of sorting conveying mechanism.
[0034] The material distribution mechanism is located upstream of the two sets of material handling conveying mechanisms, conveying corn cobs from the elevator or upstream conveyor line to the rear. Two side guards 108 are fixed to the two sides of the conveyor belt 107 to prevent the corn cobs from falling. The partition 109 is a long strip plate extending along the conveying direction, with a gap between its lower end and the surface of the conveyor belt 107 to prevent friction with the conveyor belt 107. The partition 109 divides the area above the conveyor belt 107 into two limiting grooves, left and right. The upstream corn cobs randomly fall into the two limiting grooves and, driven by the conveyor belt 107, enter the front input ends of the two sets of material handling conveying mechanisms. The output ports of the two limiting grooves are spatially connected to the input ends of the two sets of front conveying mechanisms 102.
[0035] The material distribution mechanism in this embodiment can automatically split the upstream single-path material into two paths, supplying two sets of material handling and conveying mechanisms respectively, without manual intervention. The combination of the partition 109 and the side guard 108 forms a guide channel, ensuring that the corn cobs remain orderly arranged during the distribution process, reducing crossing and blockage. At the same time, the suspended partition 109 can accommodate corn cobs of different diameters, eliminating the need for frequent adjustments.
[0036] In one embodiment, the corn cob feeding device further includes a first gantry frame 110, which is mounted on the frame 101; the blocking mechanism includes a driver 111 and a blocking plate 112; the driver 111 is mounted on the first gantry frame 110, and the blocking plate 112 is mounted on the output end of the driver 111.
[0037] The first gantry 110 spans above the output end of the front conveyor mechanism 102, providing a stable mounting base for the blocking mechanism. The driver 111 is preferably a single-acting or double-acting cylinder, with its cylinder body fixed to the first gantry 110. Its piston rod serves as the output end, connected to the blocking plate 112. The blocking plate 112 is a rectangular thin plate, its width slightly larger than the bandwidth of the front conveyor mechanism 102, capable of completely blocking the passage of the corn cobs. When the driver 111 extends, the blocking plate 112 rotates left / right or up / down to a certain height above the conveyor belt surface (slightly below the center height of the corn cob), stopping the corn cob; when the driver 111 retracts, the blocking plate 112 returns to its original position, clearing the passage.
[0038] Mounting the blocking mechanism on a separate gantry avoids interference issues associated with installation below or to the side of the conveyor belt and facilitates adjustment of the height and angle of the blocking plate 112. The cylinder-driven mechanism offers rapid response and is suitable for high-frequency intermittent blocking and stopping operations. The structure is simple, reliable, and easy to maintain.
[0039] In one embodiment, the blocking plate 112 is hinged to the baffle 105; the output end of the driver 111 is hinged to the blocking plate 112.
[0040] The baffle 105 is vertically fixed to the frame 101, serving as the hinged mounting base for the blocking plate 112. One end of the blocking plate 112 is connected to the side or top crossbeam of the baffle 105 via a hinge (or pivot), allowing the blocking plate 112 to swing around the hinge point in a horizontal or vertical plane. The actuator 111 is preferably a cylinder, with its cylinder body fixed to the first gantry 110, and the end of its piston rod hinged to the middle or free end of the blocking plate 112. When the piston rod of the actuator 111 extends, the blocking plate 112 rotates around the hinge point, moving above the conveyor belt surface of the front conveying mechanism 102, blocking the corn cobs from moving forward; when the piston rod retracts, the blocking plate 112 resets, clearing the passage. The baffle 105 simultaneously serves the dual function of separating the two sets of material handling and conveying mechanisms and providing the hinge point for the blocking plate.
[0041] By hinged the blocking plate 112 to the baffle 105, the existing baffle structure is utilized as a support, eliminating the need for additional hinge brackets, thus simplifying the equipment structure and reducing manufacturing costs. Simultaneously, the fixed hinge point position ensures stable and reliable movement of the blocking plate 112, facilitating debugging. Hinging the blocking plate 112 to the baffle 105 allows it to be more accurately positioned across the center of the output end of the front conveyor mechanism 102, resulting in better stopping performance.
[0042] In one embodiment, the corn cob handling device further includes a feeding chute 113, which is fixed relative to the frame 101 and located below the front conveying mechanism 102 and the rear conveying mechanism 103, for collecting corn cobs that fall from the front conveying mechanism 102 and the rear conveying mechanism 103.
[0043] The discharge chute 113 is an inclined U-shaped or V-shaped trough, arranged directly below the front conveyor mechanism 102 and the rear conveyor mechanism 103 along the conveying direction. Its lowest end connects to the waste collection box or the return conveyor line. During the material handling process, some corn cobs may fall from the side of the conveyor belt due to improper posture, collision, or vibration. The discharge chute 113 catches these corn cobs and discharges them, preventing them from accumulating at the bottom of the equipment and affecting operation. The discharge chute 113 effectively collects accidentally fallen corn cobs, keeps the inside of the equipment clean, and reduces the frequency of manual cleaning. The recovered corn cobs can be reused in the production line, reducing material loss.
[0044] In one embodiment, the aforementioned downstream conveying mechanism 103 includes a first sub-conveying mechanism 114 and a second sub-conveying mechanism 115; the output end of the first sub-conveying mechanism 114 is correspondingly provided with the input end of the second sub-conveying mechanism 115; and the presence detection mechanism detects the presence status of corn cobs on the first sub-conveying mechanism 114 and the second sub-conveying mechanism 115 respectively.
[0045] In this embodiment, the rear conveying mechanism 103 consists of two sub-conveying sections connected in series: a first sub-conveying mechanism 114 and a second sub-conveying mechanism 115. The output end of the first sub-conveying mechanism 114 connects to the input end of the second sub-conveying mechanism 115. After the corn cobs enter from the front end of the rear section (i.e., the inlet of the first sub-conveying mechanism 114), they pass through the two sub-sections in sequence and finally exit from the outlet of the second sub-conveying mechanism 115. The presence detection mechanism includes at least two sensors, respectively corresponding to the first sub-conveying mechanism 114 and the second sub-conveying mechanism 115, for detecting whether corn cobs are present on each sub-section. The control logic is as follows: the first sub-conveying mechanism 114 and the second sub-conveying mechanism 115 are each independently controlled to start and stop based on their respective sensor signals. Specifically, when the in-situ detection mechanism detects that there are corn cobs on both the first sub-conveying mechanism 114 and the second sub-conveying mechanism 115, the first sub-conveying mechanism 114 stops operating and waits for the corn cobs on the second sub-conveying mechanism 115 to be conveyed away. When the in-situ detection mechanism detects that the corn cobs on the second sub-conveying mechanism 115 have been conveyed away, the first sub-conveying mechanism 114 starts to convey its corn cobs to the second sub-conveying mechanism 115. At the same time, the blocking mechanism 104 between the front-end conveying mechanism 102 and the first sub-conveying mechanism 114 still operates according to the logic described in the above embodiment, but at this time the triggering condition of the blocking mechanism 104 can be set to block the front-end feeding when there is material on either the first sub-conveying mechanism 114 or the second sub-conveying mechanism 115. This two-level buffer structure allows for more precise control of the spacing of the corn cobs in the final stage before output.
[0046] It should be noted that the downstream conveying mechanism is not limited to two sub-segments. Depending on capacity and accuracy requirements, the downstream section can be configured with two or more sub-segments. A single sub-segment constitutes the basic solution; with two or more sub-segments, the buffer depth increases, further improving the uniformity of the output spacing. Those skilled in the art can select the number of sub-segments according to actual needs, all of which fall within the scope of this application.
[0047] This embodiment achieves the effect of "multi-level buffering and step-by-step release" by setting multiple serially connected sub-conveying sections in the downstream conveying mechanism and configuring them with in-situ detection and independent start / stop control. Each sub-section can serve as an independent buffer unit, effectively eliminating the stacking and uneven spacing between corn cobs. Experimental data shows that when using two-level sub-sections (i.e., a total of three-level conveying: front conveying mechanism 102 + first sub-conveying mechanism 114 + second sub-conveying mechanism 115), the corn cob output spacing error can be controlled within ±5mm.
[0048] In one embodiment, the corn cob feeding device further includes a second gantry frame 116, on which a first drive motor 117 of a first sub-conveyor mechanism 114 is provided.
[0049] The second gantry frame 116 spans above or to the side of the first sub-conveyor mechanism 114 and is used to mount the first drive motor 117. The first drive motor 117 is connected to the drive roller of the first sub-conveyor mechanism 114 via a synchronous belt or chain. Mounting the motor on the gantry frame keeps it away from the conveyor belt below, preventing damage to the motor when corn cobs fall, and also facilitates motor heat dissipation and maintenance.
[0050] The second gantry 116 provides an independent mounting position for the first drive motor 117, separating the drive unit of the first sub-conveyor mechanism 114 from the conveyor body. This results in a compact structure and easy adjustment of belt tension. The motor's elevated position reduces the impact of dust and humid environments.
[0051] Furthermore, a second drive motor 118 of the second sub-conveyor 115 is provided at the end of the frame 101 away from the first sub-conveyor 114.
[0052] The second sub-conveyor mechanism 115 is located at the very end of the entire material handling device, and its drive roller is typically located at the output end. The second drive motor 118 is directly mounted on the end side of the frame 101 and drives the drive roller of the second sub-conveyor mechanism 115 via a coupling or chain. This arrangement simplifies the structure of the second sub-conveyor mechanism 115, eliminating the need for an additional gantry frame.
[0053] The second drive motor 118 is positioned at the end of the frame 101, utilizing the space at the rear of the equipment, reducing the number of gantry frames, and lowering manufacturing costs. This location also facilitates observation and maintenance of the motor.
[0054] In one embodiment, the in-situ detection mechanism includes a first sub-position detection mechanism and a second sub-position detection mechanism, which are respectively configured to correspond to the first sub-conveying mechanism 114 and the second sub-conveying mechanism 115.
[0055] The first sub-position detection mechanism is preferably a diffuse reflection photoelectric sensor (not shown), installed above the feed end of the first sub-conveying mechanism 114, used to detect whether corn cobs have entered the first sub-conveying mechanism 114; the second sub-position detection mechanism is also a photoelectric sensor (not shown), installed at the feed end or middle of the second sub-conveying mechanism 115, used to detect whether corn cobs are present on the second sub-conveying mechanism 115. Signals from both sensors are transmitted to a controller (not shown). The controller controls the start and stop of the first sub-conveying mechanism 114 based on the signal from the first sub-position detection mechanism, and controls the start and stop of the second sub-conveying mechanism 115 based on the signal from the second sub-position detection mechanism. Furthermore, the controller can combine these two signals to determine the action of the front blocking mechanism 104.
[0056] Employing two independent sub-position detection mechanisms, the material status on each of the two sub-conveying sections can be acquired separately, providing precise control data for each buffer level. Compared to setting only one detection mechanism in the entire rear section, this embodiment can achieve more refined step-by-step linkage, further reducing material accumulation and waiting time, and improving material handling efficiency.
[0057] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
