Abstract
Description
Technical Field
[0001] This utility model relates to the field of material conveying equipment technology, specifically a fully assembled pneumatic uniform material distribution mechanism, which is suitable for uniformly distributing materials such as corn ears at multiple positions on a belt conveyor. Background Technology
[0002] In agricultural product processing lines such as corn, grains, fruits, and vegetables, as well as various bulk material conveying production lines, the material distribution belt conveyor is one of the key pieces of equipment. Its function is to evenly distribute the materials on the main conveyor line to multiple subsequent processing equipment or storage bins according to process requirements. For example, in the ear-picking room of a corn ear processing line, the material needs to be evenly distributed to multiple peeling machines working in parallel to ensure balanced load on each piece of equipment and improve overall production efficiency. Traditional material distribution mechanisms mainly adopt two forms: one is a manual mechanical control type, which changes the opening or position of the discharge baffle by manually adjusting levers or lead screws, thereby controlling the material flow direction. This method relies entirely on manual operation, has a low degree of automation, and poor material distribution accuracy and timeliness, making it difficult to meet the needs of modern automated continuous production. The other is a hydraulic cylinder driven type, which uses hydraulic cylinders as actuators to drive the discharge baffle. Although it reduces the intensity of manual labor to some extent, it can essentially only realize the opening or closing of the discharge port, and cannot achieve precise timing control of the discharge volume at each discharge point. In addition, hydraulic systems have inherent disadvantages such as complex pipeline layout, easy oil leakage that contaminates materials and the environment, high maintenance costs, and sensitivity to ambient temperature.
[0003] In terms of structural technology, traditional material distribution mechanisms are mostly welded integral structures. This type of structure requires multiple processes during production, including material cutting, assembly, welding, alignment, grinding, and painting. This not only results in a long production cycle and high costs, but also a large overall weight, making transportation and on-site hoisting difficult. More importantly, welded structures are subject to deformation stress, and if damage or modifications are needed later in use, on-site repair is extremely inconvenient and lacks flexibility.
[0004] Therefore, existing material distribution mechanisms suffer from numerous drawbacks, including insufficient automation and precision, high operating and maintenance costs, bulky structures, and outdated production processes. A new type of material distribution mechanism is needed that can achieve precise automated control while possessing advantages such as a lightweight and simplified structure, modular production, and convenient installation and maintenance, to meet the demands of modern, intelligent, efficient, and clean production. Utility Model Content
[0005] The purpose of this invention is to provide a fully assembled pneumatic uniform material distribution mechanism to solve the problems of inaccurate material distribution control, complex structure, and high maintenance cost in the prior art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a fully assembled pneumatic uniform material distribution mechanism, comprising a discharge body, wherein the discharge body is formed by connecting a first discharge body side plate and a second discharge body side plate through a horizontal tie rod, and a body support plate is fixed on the horizontal tie rod; a rotating shaft is mounted on the first discharge body side plate through two P-type bearings with seats, and the rotating shaft is connected to a discharge baffle assembly; the discharge baffle assembly is composed of a discharge baffle and a connecting plate connected by bolts; the connecting plate is connected to a cylinder through a fixed shaft; the cylinder is connected to a cylinder fixing plate through bolts, the cylinder fixing plate is fixed to a body reinforcing plate, and the body reinforcing plate is fixed to the first discharge body side plate through bolts.
[0007] Preferably, the discharge baffle assembly can rotate around a pivot under the drive of a cylinder to form two fixed positions: fully open or fully closed.
[0008] Preferably, the cylinder is controlled by an electrical program to achieve sequential unloading and unified closure of each unloading point.
[0009] Preferably, the unloading machine body can be assembled with the fixed section machine body, the head assembly, and the tail assembly to form a complete belt conveyor.
[0010] Preferably, the discharge baffle, connecting plate, rotating shaft, cylinder and each structural component of the machine body are all detachable assembly structures.
[0011] The working process of this utility model is as follows: When the belt conveyor is installed at an angle and running, the electrical control system issues commands according to a preset program to drive the cylinders at specific unloading points. The piston rod of the cylinder extends or retracts, pushing the discharge baffle assembly to rotate around the shaft through the fixed shaft and connecting plate, switching it between two fixed positions: "fully closed" (guided discharge) and "fully open" (stop discharge). After each unloading point completes unloading in sequence along the belt running direction at a set time, its baffle remains open. Once all points have finished unloading, the system closes the baffles or enters the next cycle, thereby achieving automated, uniform, and precise distribution of materials during the conveying process.
[0012] The beneficial effects of this utility model are as follows: (1) This utility model uses a cylinder to drive the unloading baffle to precisely switch between two fixed positions: "fully open" and "fully closed". In conjunction with the electrical program control system, it can accurately control the duration and sequence of each unloading point according to a preset time sequence. This not only realizes fully automated cyclic operation, replacing the traditional inefficient manual or hydraulic control, but also ensures that materials (such as corn ears) are distributed to each unloading point on demand, quantitatively and evenly, significantly improving the conveying efficiency and material distribution quality of the production line.
[0013] (2) All components in this utility model, including the fuselage frame, transmission components and actuation components, are connected and assembled using standard parts such as bolts and pins, completely eliminating the traditional welding process. This modular design makes the production process simpler, on-site installation and debugging very convenient, and greatly facilitates subsequent maintenance and parts replacement, effectively reducing production and manufacturing costs and long-term maintenance costs, and the overall appearance is neater and more beautiful.
[0014] (3) As an independent functional module, this utility model can be easily assembled with existing standard components such as fixed section body, head and tail of machine to form a complete belt conveyor, with strong layout flexibility. Its compact and integrated design optimizes the process layout of the production line, meets the urgent needs of large-scale processing production lines for multi-point material distribution on one machine, improves operating efficiency, saves equipment space, and ultimately brings significant comprehensive economic benefits to enterprises.

Detailed Implementation
[0016] The present invention will now be described in further detail with reference to the accompanying drawings.
[0017] like Figures 1 to 3 As shown, the present invention provides a fully assembled pneumatic uniform material distribution mechanism, the core of which is to achieve uniform, automatic, multi-point material distribution of materials (such as corn ears) through a fully assembled structure and a combination of pneumatic and electronic control.
[0018] First, the frame of the material distribution mechanism is the unloading body 13. The unloading body 13 is mainly composed of a first unloading body side plate 5 and a second unloading body side plate 10. The two side plates are interconnected by multiple horizontal tie rods 11, forming a stable overall frame. Above the horizontal tie rods 11, a body support plate 12 is fixed with bolts for supporting and installing other components.
[0019] On the outer side of the first unloading machine body side plate 5, a machine body reinforcing plate 8 is fixed with bolts to enhance the local structural strength. A cylinder fixing plate 9 is further fixed to this machine body reinforcing plate 8 with bolts.
[0020] Two P-type bearings 4 are bolted to the side plate 5 of the first unloading machine body. The two bearings together support a rotating shaft 3, allowing the shaft 3 to rotate smoothly.
[0021] The actuating part of the material distribution mechanism is the discharge baffle assembly. This assembly consists of a discharge baffle 1 and a connecting plate 2 connected by bolts to form a rigid whole. The discharge baffle assembly is fixedly connected to the rotating shaft 3 through its connecting plate 2, thereby allowing the entire discharge baffle assembly to rotate around the axis of the rotating shaft 3.
[0022] The discharge baffle assembly is powered by a cylinder 6. The tail of the cylinder 6 is hinged to the cylinder fixing plate 9 by a pin or bolt, allowing it to swing. The piston rod end of the cylinder 6 is hinged to the connecting plate 2 on the discharge baffle assembly by a fixed shaft 7.
[0023] Thus, a complete crank-rocker mechanism is formed: the extension and retraction of cylinder 6 pushes connecting plate 2 through fixed shaft 7, thereby driving the entire discharge baffle assembly to rotate around rotating shaft 3, realizing the switching between the two positions of discharge baffle 1 "open" and "closed".
[0024] The unloading body 13 is the core functional module, and its two ends can be connected to the fixed section body 14 by flanges or bolts. The entire belt conveyor is assembled from multiple fixed section bodies 14, at least one unloading body 13 as described in this utility model, and head assembly 15 (drive unit) and tail assembly 16 (tensioning unit) located at both ends.
[0025] In actual installation, the entire belt conveyor is installed at an angle (viewed from the head or tail, one side is higher and the other side is lower). The discharge body 13 is usually installed on the higher side of the belt conveyor, while the discharge baffle 1 can extend to the lower side of the belt surface when it rotates downward, thereby guiding the material out of the belt.
[0026] Its automated workflow is as follows: Initialization state: When the system is powered on, all cylinders 6 are in the extended state, which drives the discharge baffles 1 of each discharge point to rotate to the "fully open" position (i.e., perpendicular to the belt surface or in the retracted state). At this time, the material runs normally on the belt and no discharge is performed.
[0027] Sequential unloading: When unloading is required at the first unloading point, the electrical control system (such as a PLC) sends a signal to cylinder 6 at the first unloading point according to a preset timing sequence. The piston rod of cylinder 6 retracts, pushing the discharge baffle 1 to rotate to the "fully closed" position (i.e., tilted and inserted into the material flow of the conveyor belt), and begins to guide the material at that position to the designated outlet. After a preset time (this time determines the unloading volume), the PLC controls cylinder 6 to extend, and the discharge baffle 1 returns to the "fully open" position, stopping the unloading.
[0028] Subsequent unloading point operations: After the first unloading point is completed, the PLC controls the cylinder 6 of the subsequent unloading points to perform the same "extend-hold-retract" action in the direction of belt running, so as to realize the sequential and quantitative unloading of materials along the conveying direction.
[0029] Cycle and Reset: After all unloading points have completed one unloading cycle, all discharge baffles 1 remain in the "fully open" position, and the belt conveyor runs unloaded. The process is repeated from the first unloading point when the next work cycle begins. Through precise control of the electrical program, accurate control of the unloading amount at each unloading point can be achieved, resulting in uniform material distribution.
[0030] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, based on the technical teachings provided by this utility model and as common knowledge in the field, other equivalent modifications and improvements can be made, and these should also be considered within the protection scope of this utility model.
