Description

Technical Field

[0001] This utility model relates to the field of replenishment machine technology, and in particular to a retractable replenishment machine. Background Technology

[0002] In grain storage replenishment operations, the core design of the telescopic replenishment machine lies in the flexible displacement of the conveyor belt through a scissor fork mechanism. Its main operation involves utilizing the telescopic characteristics of the hydraulically driven scissor fork mechanism to move the entire conveyor belt, precisely connecting it to the grain filling ports at different locations within the grain depot, efficiently transferring externally transported grain into the depot. The significance of this design lies in breaking through the spatial limitations of traditional fixed conveyor equipment. It allows for flexible adjustment of the operating position according to the storage needs of different areas within the grain depot, significantly improving the coverage and flexibility of replenishment operations, reducing the problem of low space utilization in grain depots caused by fixed equipment locations, and providing fundamental support for large-scale, automated grain depot operations.

[0003] However, telescopic loading and replenishing machines often use conveyor belts to directly scatter materials into the grain depot. When there are differences in the storage height and spatial shape of different areas in the grain depot, the fixed-angle scattering trajectory is difficult to adapt, causing the grain to continuously fall into the same area, forming local accumulation. This will cause the single grain inlet to continuously feed, exceeding the carrying capacity of that area. Eventually, the grain in that area will collapse. After collapsing, the grain will form dense clumps due to compression, greatly reducing its permeability and making it easy for mold to grow and produce harmful substances such as aflatoxin.

[0004] Based on the above viewpoints, those skilled in the art have proposed a retractable loading and replenishment machine. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a retractable grain loading and replenishment machine. This retractable grain loading and replenishment machine can flexibly adapt to the feeding needs of different areas of the grain depot by adjusting the grain throwing angle, fundamentally solving the problem of excessive local accumulation of grain. It not only ensures the uniformity of grain distribution inside the grain depot, but also reduces the risk of grain mold and overheating caused by accumulation. At the same time, it reduces the workload of manual grain leveling and improves the safety and efficiency of grain storage.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, by adjusting the angle of grain scattering, it can flexibly adapt to the feeding needs of different areas of the grain depot, fundamentally solving the problem of excessive local accumulation of grain. This not only ensures the uniformity of grain distribution inside the grain depot, but also reduces the risk of grain mold and heat generation caused by accumulation. At the same time, it reduces the workload of manually leveling grain, and improves the safety and efficiency of grain storage.

[0022] 2. In this utility model, the design of the air nozzle synchronously adjusting with the conveyor belt angle, combined with the linkage control of the angle sensor and the flow regulating valve, can accurately address grain accumulation at different conveyor belt angles. This not only effectively disperses accumulated grain on the conveyor belt, preventing conveyor interruptions due to blockages and ensuring continuous and stable operation, but also achieves rational energy utilization through automatic adjustment of air intake, reducing equipment operating energy consumption and extending the device's service life.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example, refer to Figures 1-4This utility model provides an embodiment of a retractable hopper replenishment machine, including a hydraulic scissor fork mechanism 1, a belt conveyor 2 disposed at the top of the hydraulic scissor fork mechanism 1, and a feeding hopper 3 disposed at the rear end of the belt conveyor 2. It also includes a feeder 4, disposed at the bottom front end of the feeding hopper 3, and comprising: a support frame 42 disposed directly below the output end of the belt conveyor 2, with arc-shaped movable grooves 45 formed on both side walls near the front end; and two sets of drive rollers 43 respectively installed on the rear side of the support frame 42 and within the movable grooves 45 formed at the front end of the support frame 42. A conveyor belt 44 is fitted around the outer side of the two transmission rollers 43; a drive mechanism 46 is installed at the bottom of the support frame 42 to drive the front transmission roller 43 to slide along the track of the movable groove 45; an air nozzle 411 is rotatably connected to the rear side of the support frame 42 and is positioned directly above the conveyor belt 44; two sets of curved connecting rods 48 are respectively fixed at one end to the rotating shafts on both sides of the air nozzle 411 and rotatably connected to the rotating shafts on both sides of the front transmission roller 43; the movable groove 45 is set with the rotating shaft of the air nozzle 411 as the center, so that the front transmission roller 43 can slide along its arc extension direction.

[0033] Reference Figure 2 The bottom sides of the support frame 42 are welded with two upward-extending plates to form receiving hoppers 41. The receiving hoppers 41 are fixed to the bottom of the output end of the belt conveyor 2 by bolts. The outer side wall of the support frame 42 is equipped with a transmission motor assembly 47 for the rear drive roller 43 to rotate.

[0034] Reference Figure 3 An angle sensor 49 is installed on the outer wall of the support frame 42. The angle sensor 49 is directly opposite the rotating shaft of the nozzle 411. A flow regulating valve 410 is installed on the air inlet of the nozzle 411. The angle sensor 49 can be selected as WTB28-2P430.

[0035] Reference Figure 4 The drive mechanism 46 includes a transmission cylinder 461 mounted on the bottom of the support frame 42. A connecting rod 462 is connected to the movable end of the transmission cylinder 461 by a threaded structure. Movable connecting rods 463 are rotatably connected to both sides of the connecting rod 462. The other ends of the two movable connecting rods 463 are rotatably connected to the shaft of the front transmission roller 43. When the transmission cylinder 461 drives the connecting rod 462 to move forward, the movable connecting rods 463 located on both sides of the connecting rod 462 drive the front transmission roller 43 to slide along the extension direction of the movable groove 45.

[0036] Working Principle: This device uses a hydraulic scissor fork mechanism 1 to drive a belt conveyor 2 to the grain filling port of the grain depot. Grain is then spread onto the belt conveyor 2 through the feed hopper 3. Driven by the belt conveyor 2, the grain continuously flows into the grain depot. When the grain is conveyed to the spreader 4, it falls onto the conveyor belt 44 through the receiving hopper 41. At this time, driven by the conveyor motor assembly 47, the rear drive roller 43 drives the conveyor belt 44 and the front drive roller 43 to rotate together, thus spreading the grain that has fallen on the conveyor belt 44. When it is necessary to adjust the spreading angle, the electric cylinder 461 drives the connecting rod 462 to move forward. At this time, the movable connecting rods 463 on both sides of the connecting rod 462 drive the front drive roller 43 to slide along the extension direction of the movable groove 45, thereby changing the angle of the entire conveyor belt 44 and thus changing the grain spreading angle. This allows the conveying mechanism to avoid the grain from accumulating in a certain area of ​​the grain depot by changing the grain spreading angle. Excessive accumulation occurs at the point where the transmission roller 43 slides along the direction of the movable groove 45. The curved connecting rod 48 is driven to slide along the direction of the movable groove 45, thereby driving the air nozzle 411 to rotate. The air nozzle 411 is connected to an external air source through the flow regulating valve 410, thereby using the air source to blow away the grain accumulated on the conveyor belt 44, preventing excessive accumulation of grain on the conveyor belt 44, which would prevent the conveyor belt 44 from properly scattering the grain. At the same time, the angle sensor 49 can detect the rotation angle of the air nozzle 411 shaft and feed the detection signal back to the controller. The controller generates analog information based on the detection signal fed back by the angle sensor 49 and outputs the analog signal to the flow regulating valve 410 through the output module. The controller adjusts the opening of the flow regulating valve 410 according to the analog signal, thereby increasing the air intake. This allows the air nozzle 411 to be adjusted according to the angle of the conveyor belt 44. The appropriate air intake assists in scattering the grain. The controller model S7-1214C is optional.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
