Description

Technical Field

[0001] This utility model belongs to the field of warehousing technology, and in particular to a drop ladder for preventing grain from breaking when falling from a height. Background Technology

[0002] In the grain production sector, grain is usually stored in granaries after harvest. When grain enters the granary, it is usually dropped from the top of the granary into the interior by its own weight. However, when storing grain in this way, the grain itself carries dust, which will spread around after entering the granary. Therefore, fans are designed to blow away the dust, but the dust removal capacity is relatively weak.

[0003] A search revealed a Chinese patent document (authorization announcement number CN219238676U) entitled "A Drop Ladder for Preventing Grain from Breaking During a High-Altitude Fall." This ladder includes a transfer silo, a distribution silo fixedly installed in the center of the inner top surface of the transfer silo, a feed pipe located at the center of the top of the transfer silo, and a guide pipe connected to the outer surface of the transfer silo. The transfer silo is equipped with a dust removal mechanism, and the guide pipe is equipped with a buffer mechanism. The dust removal mechanism includes a conical cylinder, a first filter screen, a sieve plate, a partition plate, a second filter screen, and a fan. The buffer mechanism includes a first buffer plate, a second buffer plate, a connecting rod, a slider, and a buffer spring. This invention, through its dust removal and buffer mechanisms, effectively removes dust and impurities from the grain, achieving good cleaning results, avoiding environmental impact, and preventing grain breakage during descent, thus providing good protection. Since grain itself carries dust, the dust disperses after entering the grain silo, necessitating a fan for dust removal, but this method has limited capacity. Summary of the Invention

[0004] The purpose of this invention is to provide a drop ladder to prevent grain from breaking when falling from a height, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drop ladder to prevent grain from breaking when falling from a height, comprising:

[0006] The transfer warehouse has a material collection hopper fixedly connected to its inner wall;

[0007] The filter ring is fixedly connected to the inner wall of the transfer chamber. A connecting cone is provided between the filter ring and the material hopper. A funnel-shaped filter screen and multiple connecting rods are connected between the connecting cone and the filter ring.

[0008] Multiple inclined collection hoppers are connected to the transfer bin, and the collection hoppers are connected to a hollow drop ladder body;

[0009] The lower half of the transfer chamber is funnel-shaped, and the bottom of the transfer chamber is connected to a water storage tank. Multiple fans are embedded in the top of the water storage tank, and a ring is installed at the bottom of the fan. The inner wall of the ring is connected to a dustproof net. A rotary motor is installed at the bottom of the water storage tank. The output shaft of the rotary motor passes through the water storage tank and is connected to a rotating rod. The outer periphery of the rotating rod is connected to a stirring blade for agitating the water and a cleaning brush for cleaning the dustproof net.

[0010] As a preferred embodiment, the bottom of the hopper is connected to a material collecting pipe.

[0011] As a preferred embodiment, the inner wall of the drop ladder body is connected with multiple staggered inclined baffles, and the top of the inclined baffles is glued with rubber pads to prevent the grain from breaking when falling from a height.

[0012] As a preferred embodiment, the inner cavity of the transfer silo is equipped with a dispersing cone, and the inner wall of the material hopper is welded with multiple limiting rods.

[0013] As a preferred embodiment, the bottom end of the dispersing cone is welded with multiple hollow tubes that are sleeved around the outer periphery of the limiting rod, and a spring is connected between the limiting rod and the dispersing cone to prevent the grain from falling and breaking from a height.

[0014] As a preferred embodiment, a viewing window is embedded in the side of the water storage tank, and a movable plate is rotatably connected to the top of the water storage tank.

[0015] As a preferred implementation, the top of the transfer silo is provided with a feeding channel, and the inner wall of the transfer silo is connected with multiple four-sided dispersion blocks that abut against the collection hopper and the filter screen.

[0016] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0017] This drop ladder, designed to prevent grain from breaking when falling from a height, disperses the grain after receiving it at the transfer point. When the grain falls onto the dispersion cone, the spring contracts to provide cushioning protection. The drop ladder body can then unload the grain. During the subsequent unloading process, multiple staggered inclined baffles provide blocking protection, and rubber pads also provide elastic cushioning protection.

[0018] This drop ladder, designed to prevent grain from breaking when falling from a height, uses a funnel-shaped filter screen during the grain feeding process. As the grain falls, debris and small particles are drawn away by a fan, removing some of the dust near the grain. During descent, the grain falls into water, and the mixing of the liquid reduces its impact on the fan. A rotating motor drives a rotating rod, which in turn rotates the agitator and cleaning brush. The agitator stirs the liquid to prevent the formation of a water film, improving dust removal efficiency. The cleaning brush cleans the dust screen, reducing the possibility of clogging and affecting the fan.

[0019] This drop ladder, designed to prevent grain from breaking when falling from heights, not only protects the grain from breakage but also handles dust and debris. Attached Figure Description

[0031] The connection method can adopt existing methods such as bonding, welding, bolting, etc., depending on the actual needs. Techniques, methods and equipment known to those skilled in the art may not be discussed in detail. However, where appropriate, the techniques, methods and equipment should be regarded as part of the specification. The proportions of the components in the drawings are for reference only and can be adjusted to a certain extent according to the actual use.

[0032] Please see Figures 1 to 5 As shown, a drop ladder for preventing grain from breaking when falling from a height, in this embodiment, includes:

[0033] Transfer bin 1, with a material collection hopper 2 fixedly connected to the inner wall of transfer bin 1, and a material collection pipe 17 connected to the bottom end of the material collection hopper 2;

[0034] The filter ring 3 is fixedly connected to the inner wall of the transfer chamber 1. A connecting cone 4 is provided between the filter ring 3 and the material hopper 2. A funnel-shaped filter screen 5 and multiple connecting rods 6 are connected between the connecting cone 4 and the filter ring 3.

[0035] Multiple inclined collection hoppers 7 are connected to the transfer bin 1. The collection hoppers 7 are connected to a hollow drop ladder body 8. The inner wall of the drop ladder body 8 is connected to multiple staggered inclined baffles 18. The top of the inclined baffles 18 is glued with rubber pads 19 to prevent the grain from falling and breaking. The grain falls into the collection hopper 2, is collected and discharged from the collection pipe 17, dispersed by the connecting cone 4, passes through the filter screen 5, falls into the collection hopper 7, and then enters the drop ladder body 8. The multiple staggered inclined baffles 18 can block and protect, and the rubber pads 19 can also provide elastic buffer protection, and finally discharge the grain.

[0036] The lower half of the transfer chamber 1 is funnel-shaped. The bottom of the transfer chamber 1 is connected to a water storage tank 9. Multiple fans 10 are embedded in the top of the water storage tank 9. A ring 11 is installed at the bottom of each fan 10, and a dustproof net 12 is connected to the inner wall of the ring 11. A rotary motor 13 is installed at the bottom of the water storage tank 9. The output shaft of the rotary motor 13 passes through the water storage tank 9 and is connected to a rotating rod 14. A stirring blade 15 for agitating the liquid and a cleaning brush 16 for cleaning the dustproof net 12 are connected to the outer periphery of the rotating rod 14. During the grain feeding process, the grain passes through the funnel-shaped... During the descent of filter screen 5, debris and small particles fall into the water, and the mixing of the water and liquid reduces the subsequent impact on fan 10. Fan 10 then draws in air to remove some of the dust near the grain. During the descent, rotary motor 13 drives rotating rod 14 to rotate, which in turn drives stirring blade 15 and cleaning brush 16 to rotate. Stirring blade 15 agitates the water to prevent the formation of a water film on the surface, improving the dust removal effect. Cleaning brush 16 cleans dustproof screen 12, reducing the possibility of dustproof screen 12 becoming clogged and affecting fan 10.

[0037] The inner cavity of the transfer bin 1 is equipped with a dispersing cone 20. Multiple limiting rods 21 are welded to the inner wall of the hopper 2. Multiple hollow tubes 22 are welded to the bottom of the dispersing cone 20 and sleeved around the outer periphery of the limiting rods 21. A rubber sleeve with elasticity and energy dissipation capacity is bonded to the outer periphery of the limiting rods 21. A spring 23 is connected between the limiting rods 21 and the dispersing cone 20 to prevent the grain from falling and breaking from a height. The external feeding equipment introduces grain into the transfer bin 1. The grain falls onto the dispersing cone 20, and the dispersing cone 20 disperses the grain. After the grain falls onto the dispersing cone 20, the spring 23 contracts to provide shrinkage and buffer protection.

[0038] A viewing window is embedded in the side of the water storage tank 9. A movable plate 24 is rotatably connected to the top of the water storage tank 9. A feeding channel is opened at the top of the transfer chamber 1. Multiple four-sided dispersion blocks are connected to the inner wall of the transfer chamber 1 to block the collection hopper 7 and the filter screen 5. The blocking of the four-sided dispersion blocks can prevent the grain from falling between the two collection hoppers 7 and ensure that it falls into the collection hopper 7.

[0039] The tips of the connecting cone 4 and the dispersing cone 20 are rounded to avoid hardening of the tips and damage to the grain. Rubber pads can also be glued to the tips of the connecting cone 4 and the dispersing cone 20 for protection.

[0040] The fan 10 and the rotary motor 13 are conventional instruments. Their working principles, dimensions and models are not related to the problem solved by this application, so they will not be described in detail. The control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0041] Working principle

[0042] The drop ladder designed to prevent grain from breaking when falling from a height involves pre-activating the fan 10 and the rotary motor 13, and connecting the drop ladder body 8 to external equipment. The external feeding equipment introduces grain into the transfer silo 1. The grain falls onto the dispersing cone 20, which disperses the grain. After the grain falls onto the dispersing cone 20, the spring 23 contracts to provide cushioning protection. The grain then falls into the collecting hopper 2 and is collected and discharged from the collecting pipe 17. After being dispersed by the connecting cone 4 and passing through the filter screen 5, the grain falls into the collecting hopper 7 and then into the drop ladder body 8. Multiple staggered inclined baffles 18 provide blocking protection, and rubber pads 19 provide elastic cushioning protection before finally discharging the grain.

[0043] During the grain feeding process, the grain passes through the funnel-shaped filter screen 5. As it falls, debris and small-sized impurities fall into the water. The mixing of the water and liquid reduces the subsequent impact on the blower 10. The blower 10 then draws in air to remove some of the dust near the grain. During the descent, the rotary motor 13 drives the rotating rod 14 to rotate, which in turn drives the stirring blade 15 and the cleaning brush 16 to rotate. The stirring blade 15 agitates the water to prevent the formation of a water film on the surface, thus improving the dust removal effect. The cleaning brush 16 cleans the dustproof net 12, reducing the possibility of the dustproof net 12 becoming clogged and affecting the blower 10.
