It solves the technical problems of low efficiency and poor accuracy of traditional manual sorting and easy blockage of mechanical sorting.

[0005] This utility model provides a multi-channel corn length sorting mechanism, including: The mounting frame has an inclined mounting plate on top; The inclined mounting plate is equipped with threaded support structures at its lower end and on both the front and rear sides of the mounting frame.

The mounting window is trapezoidal with the smaller end at the bottom, and an arched frame is fixed to the bottom of the mounting window. The inner wall of the installation window is fixed with baffles on both the front and rear sides, and a V-shaped sorting cavity is formed between the front and rear baffles. The lifting pallet structure has its drive unit mounted on an arched frame and its movable part slidably inserted into the installation window as a cargo pallet. The top of the lifting pallet structure forms an inclined slope, with its lower end facing forward.

[0006] As a further optimization, to allow manual operation to slide the corn laterally from top to bottom along the V-shaped sorting cavity until both ends of the corn are in contact with the side guards, a strip-shaped inclined plate supports the corn at this position. A timed electric push rod moves the strip-shaped inclined plate downwards, and the corn it carries slides down the inclined slope.

The lifting pallet structure includes: An electric actuator, which is fixed to the top surface of the arched frame; The lower end of the electric push rod output is fixedly connected to a horizontal plate through the top surface of the arched frame. A strip-shaped inclined plate, the lower end of which is fixedly connected to a horizontal plate; The inclined slope is integrally formed on the top surface of the strip-shaped inclined plate.

[0007] As a further optimization, in order to form a V-shaped sorting cavity and serve as a mounting bracket for the lifting pallet structure, the inclined mounting plate includes: An inclined platform with a mounting plate fixed at its lower end; The installation window is opened along the length of the inclined platform and the installation plate; The arched frame is fixed inside the mounting window on the mounting plate, and the baffle is fixed to the front and rear sides of the inner wall of the mounting window on the inclined platform.

[0008] As a further optimization, in order to connect the lower end of the fixed inclined mounting plate and the end of the mounting frame on the same side, and to leave sufficient space between them, the threaded support structure includes: A long screw passes through the lower end of the inclined mounting plate and the mounting frame; The long screw is screwed with a first nut, a second nut, and a third nut; The long screw's nut and first nut are clamped on the upper and lower sides of the lower end of the inclined mounting plate, while the second nut and third nut are clamped on the upper and lower sides of the mounting frame.

[0009] As a further optimization, in order to classify and transport the corn that slides down at different heights after the inclined plate descends to the front or the next process, and to achieve sorting of corn by length, the top surface of the mounting frame is fixed with an inclined multi-segment partitioned conveyor mechanism, the discharge end of which faces the front. The inclined multi-segment partitioned conveyor mechanism and the inclined mounting plate have the same inclination angle, and the inclined multi-segment partitioned conveyor mechanism is located below the inclined mounting plate. The inclined multi-segment partitioned conveying mechanism includes: An inclined multi-segmented conveyor belt has a low support fixed to the bottom surface of its lower edge and a high support fixed to the bottom surface of its upper edge. The lower edges of the short and tall supports are integrally formed with connecting ear plates, which are fixed to the top surface of the mounting frame by bolts.

[0010] As a further optimization, in order to classify and transport corn that slides down at different heights after the inclined plate descends to the next process or the next step, and to achieve corn sorting by length, the inclined multi-segmented separator conveyor belt includes: There are two side panels, which are distributed parallel to each other on the left and right sides. Both of the two side plates are rotatably fitted with round rollers on their front and rear sides, and belts are sleeved on the outer walls of the front and rear round rollers. The circular roller and the two side plates are provided with four sets of parallel fixed components; A shaft is embedded at the center of the four front rollers, which rotates at the front end of the side plate; A drive motor is fixed to the front side of the outer side plate; The output end of the drive motor is fixedly connected to the end of the shaft. A partition is fixed to the upper end of the side plate.

[0011] As a further optimization, in order to collect small corn or impurities that slide down along the inclined and horizontal plates, a collection box is provided at the lower end of the inclined mounting plate, with its upper end at the same height as the lower end of the inclined mounting plate. Limit plates are fixed on both the front and rear sides of the mounting frame located at the lower end of the inclined mounting plate. The collection box is inserted into the front and rear limiting plates.

[0012] As a further optimization, in order to collect excessively small corn kernels or impurities that slide down along the inclined and horizontal strips, the collection box includes: A rectangular box with a right-angled U-shaped baffle fixed to the side of its upper edge away from the inclined mounting plate.

[0013] As a further optimization, in order to provide stable support for the device, the mounting frame includes: The base plate has mounting supports fixed at all four corners of its bottom surface.

[0014] This utility model provides an improved multi-channel corn length sorting mechanism, which has the following improvements and advantages compared with the prior art: I. Achieved efficient and automated multi-channel parallel sorting: This invention constructs multiple parallel V-shaped sorting channels by setting an inclined mounting plate with multiple independent installation windows and lifting pallet structures, which can simultaneously sort a large number of corn by length. Compared with traditional manual sorting and single-channel equipment, the sorting efficiency has been improved by orders of magnitude, greatly reducing labor intensity.

[0015] II. High sorting accuracy and good consistency: The sorting method combines a V-shaped sorting cavity formed by the guard edge with a liftable pallet. The corn is stable in the V-shaped cavity, and its length is the only significant variable that determines its center of gravity. By controlling the timing of the descent of the lifting pallet, precise and objective separation is achieved, which effectively eliminates the subjective differences of manual sorting and ensures the consistency and reliability of the sorting results.

[0016] Third, it effectively avoids material blockage and ensures continuous operation: The unique V-shaped sorting cavity design, with a trapezoidal structure at the lower end and an inclined slope, provides a smooth channel for the rolling of corn, avoiding the accumulation or jamming of corn at the sorting port, and ensuring the smoothness of the sorting process and the continuity of production.

[0017] IV. Ingenious structural design, high integration, and minimal damage to corn: The entire mechanism integrates conveying, sorting, and collection functions into one compact layout. During the sorting process, the corn mainly relies on its own gravity to roll on the inclined surface. The lifting pallet moves smoothly, and the side guards and inclined slope play a good guiding and buffering role, minimizing collisions and damage to the corn husks and ensuring product quality.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] In the following description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; or they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] Furthermore, in the following description of this utility model, unless otherwise stated, "multiple", "multiple groups", or "multiple roots" means two or more.

[0025] Please see Figure 1-7The present invention provides a technical solution: a multi-channel corn length sorting mechanism, the overall structure of which is built on a mounting frame 1. The mounting frame 1 constitutes the rigid foundation of the equipment, which mainly includes a rectangular base plate 11 and four mounting pillars 12 vertically fixed at the four corners of the bottom surface of the base plate 11. These mounting pillars 12 play the role of supporting and raising the entire equipment, which facilitates the installation and ventilation of the bottom structure.

[0026] On the top surface of the mounting frame 1, near the high end, an inclined multi-segmented conveyor mechanism 2 is fixedly installed by bolts. The core of this mechanism is an inclined multi-segmented conveyor belt 21.

[0027] like Figure 5 and Figure 6 As shown, the inclined multi-segmented conveyor belt 21 is composed of four parallel and identical conveyor units arranged side by side to achieve multi-channel independent conveying. Each conveyor unit includes two side plates 212 arranged parallel to each other. Between the two side plates 212, a circular roller 211 is rotatably mounted at the front and rear ends via bearings. A ring belt is sleeved on the front and rear circular rollers 211. In order to drive all conveyor units synchronously, a through shaft 213 is embedded and fixed at the axis of the four circular rollers 211 on the front side. The shaft 213 is supported at the front end of each side plate 212 by bearing seats. A drive motor 214 is fixed on the outermost side plate 212 by a mounting seat. Its output end is fixedly connected to the end of the shaft 213 by a coupling. When the drive motor 214 works, it drives the four circular rollers 211 on the front side to rotate synchronously through the shaft 213, thereby driving the four belts to move forward synchronously. In addition, vertical partitions 215 are fixed at the upper ends of the two side plates 212 of each conveying unit. These partitions 215 clearly separate the adjacent conveying channels to prevent corn from slipping through the channels during the conveying process.

[0028] like Figure 2 As shown, an inclined mounting plate 3 is provided above the inclined multi-segment divided conveyor mechanism 2. The inclined mounting plate 3 is welded together from a main inclined platform 31 and a mounting plate 32 fixed to its lower end. The overall inclination angle of the inclined mounting plate 3 is consistent with that of the inclined multi-segment divided conveyor mechanism 2 below.

[0029] like Figure 4As shown, the connection between the inclined mounting plate 3 and the mounting frame 1, especially at its lower end, is achieved through a threaded support structure 6. The threaded support structure 6 includes a sufficiently long screw 61, which passes vertically through the pre-set through hole of the mounting plate 32 and the corresponding through hole on the base plate 11 of the mounting frame 1. A first nut 62, a second nut 63, and a third nut 64 are screwed onto the screw 61 from top to bottom. By precisely tightening these nuts, the nuts of the screw 61 and the first nut 62 are tightly clamped on the upper and lower surfaces of the mounting plate 32, while the second nut 63 and the third nut 64 are tightly clamped on the upper and lower surfaces of the base plate 11 of the mounting frame 1. This design not only achieves a firm connection.

[0030] like Figure 2 As shown, two elongated mounting windows 35 are arranged side by side along the length of the inclined platform 31 and the mounting plate 32. The mounting windows 35 penetrate the plate body and are trapezoidal. The lower end of the mounting window 35 near the mounting plate 32 is the narrow end with a smaller width, while the other end near the higher position of the inclined platform 31 is the wide end. At the narrow opening at the lower end of each mounting window 35, that is, in the part of the mounting plate 32, an arched frame 34 is fixedly installed. This frame provides support and space for the sorting operation. At the same time, on the front and rear sides of the inner wall of the mounting window 35 in the inclined platform 31, a baffle 33 is fixed. These two baffles 33 extend from the wide end to the narrow end of the mounting window 35, and the gap between them gradually narrows, thus forming a V-shaped sorting cavity between them. When using it, hold the corn cob and slide it from top to bottom along the V-shaped sorting cavity. The final stopping position is determined by its own length. The longer the length, the higher it stops in the V-shaped sorting cavity.

[0031] like Figure 3 As shown, a lifting pallet structure 4 is correspondingly provided in each installation window 35. This structure includes an electric push rod 41, the cylinder of which is vertically fixed to the top surface of the arched frame 34. The push rod of the electric push rod 41 passes downward through the through hole on the top surface of the arched frame 34, and its end is fixedly connected to a horizontal plate 42. The lower end of a strip-shaped inclined plate 43 is fixedly connected to the horizontal plate 42, and its upper end extends upward and slides into the installation window 35. The top surface of the strip-shaped inclined plate 43 is processed or formed into a smooth inclined slope 44, and the lower end of the slope 44 faces the front of the mechanism, i.e. the discharge direction. In the initial state or the supporting state, the electric push rod 41 is in the retracted state, the strip-shaped inclined plate 43 is raised, and the inclined slope 44 at its top is smoothly connected to the bottom surface of the V-shaped sorting cavity, jointly supporting the corn that has stopped.

[0032] Specifically, in this embodiment, the electric push rod 41 is controlled by an external controller to raise and lower at regular intervals. The time interval is set according to the process duration to ensure that the corn is placed in the retracted state of the electric push rod 41. After the corn is placed and its height in the V-shaped sorting cavity is determined by its length, the electric push rod 41 extends and drives the strip inclined plate 43 to slowly descend. The corn rolls forward along the inclined slope 44. When the gap between the strip inclined plate 43 and the side guards 33 is larger than the outer diameter of the corn, the corn slides forward along the gap.

[0033] like Figure 7 As shown, a collection box 5 is provided on the outer side of the lowest end of the inclined mounting plate 3 for collecting short corn or impurities that cannot be effectively sorted. The length of the short corn or impurities is less than the minimum distance between the two side guards 33. The collection box 5 includes a rectangular box 51 and a right-angled U-shaped baffle 52 fixed on the side of its upper edge away from the inclined mounting plate 3. The baffle 52 can prevent corn or impurities from rolling out of the collection box 5.

[0034] like Figure 1 As shown, in order to facilitate picking up, placing and cleaning, a limiting plate 7 is fixed on the front and rear sides of the inclined mounting plate 3 on the mounting frame 1. The rectangular box 51 part of the collection box body 5 can be inserted between the two limiting plates 7 to achieve positioning and fixation.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
