Description

Technical Field

[0001] The invention belongs to the technical field of grain storage, and in particular to a device for reducing grain breakage when entering a warehouse. Background Art

[0002] In modern grain storage technology, ensuring the integrity of grain during the warehousing process is a key link in maintaining its quality and reducing losses. A significant problem faced by traditional grain warehousing operations is that when grain falls freely from a certain height to the bottom of the silo, due to the lack of effective buffering measures and technical means to efficiently and dynamically control the grain falling process, grain particles will directly hit the silo wall or the surface of the accumulated grain. This high-intensity impact force often causes grain particles to break. At the same time, most of the existing silo structures are based on static design and cannot be adjusted in time according to the actual flow of grain entering the silo, resulting in limited buffering effects, especially when dealing with grains of different types and states, the breakage rate is difficult to be effectively controlled. Especially when facing grain crops with fragile shells such as rice, the shortcomings of traditional static silo structures are more prominent. Due to the lack of the ability to dynamically adjust the feeding rate and buffering strength, grain falls directly from the conveying device to the bottom or side wall of the silo. The high-intensity impact easily causes a large amount of grain to be damaged, reducing the quality of the grain.

[0003] After searching, the existing Chinese patent publication number: CN108438936B is a grain silo buffer device capable of reducing the grain breakage rate, including a shell, a rice outlet pipe, a buffer tube, an elastic collision component, a discharge port and a base, the buffer tube is arranged inside the shell, the rice outlet pipe is installed at the middle position above the shell, the shell inner wall is fixedly welded above the two side walls of the rice outlet pipe, a base is arranged below the shell, the shell and the base are fixedly connected through a buffer device, and the discharge port is welded on the lower surface of the buffer tube, characterized in that elastic collision components are staggered on the side walls of the inner cavity of the buffer tube, and the elastic collision component includes an upper fixed seat, a first elastic plate, a second elastic plate and a buffer pad.

[0004] The cited patent documents also have the same problem, and the shortcomings of the static silo structure are more prominent. Since there is no ability to dynamically adjust the feeding rate and buffer strength, the grain falls directly from the conveying device to the bottom or side wall of the silo. The high-intensity impact easily causes a large amount of grain to be damaged, reducing the quality of the grain. Summary of the invention

DETAILED DESCRIPTION

[0037] In the following description, a large number of specific details are provided to provide a more thorough understanding of the present invention. However, it is apparent to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some technical features well known in the art are not described.

[0038] Unless otherwise defined, the up, down, left, right, front, back, inside and outside directions involved in this document are based on the up, down, left, right, front, back, inside and outside directions in the figures shown in the present invention, and are explained here together.

[0039] This embodiment discloses Figures 1 to 8 The device for reducing grain crushing when entering a silo shown in the figure comprises a silo 1, a first silo anti-crushing component 7 and a second silo anti-crushing component 16;

[0040] in;

[0041] The bottom of the granary 1 is provided with a buffer support seat 2 for buffering when grain enters the granary. The inner bottom wall of the buffer support seat 2 is symmetrically installed with multiple hydraulic buffer dampers 28. The tops of the multiple hydraulic buffer dampers 28 are connected with a buffer support plate 27. The granary 1 is fixedly installed on the top surface of the buffer support plate 27. The top surface of the buffer support seat 2 is symmetrically welded with support rods 5. The tops of the two support rods 5 are welded with positioning rings 4 for sleeves on the outer wall of the granary 1. The granary 1 is vertically raised and lowered in the positioning rings 4. Multiple supporting feet 3 are symmetrically welded on the bottom surface of the buffer support seat 2. Discharge pipe openings 29 are opened on the inner bottom wall of the buffer support seat 2 and the top surface of the buffer support plate 27. The discharge pipe passes through the discharge pipe opening 29 and passes through the discharge funnel 22 of the granary 1.

[0042] Specifically, the feeding funnel 22 is located at the bottom of the anti-crushing receiving tube 12, and is used to collect and guide the grain to smoothly enter the subsequent processing or storage link, ensuring that the grain can leave the anti-crushing receiving tube 12 in an orderly and rapid manner to avoid accumulation and secondary crushing.

[0043] Specifically, the hydraulic buffer damper 28 is installed on the top of the buffer support plate 27. The hydraulic system of the buffer damper 28 absorbs and buffers the impact energy of the grain pile on the bottom when it falls, prevents direct hard landing, improves the bottom buffering capacity, and reduces structural vibration and noise.

[0044] Specifically, the first silo anti-breakage component 7 is arranged at the upper part of the inner cavity of the granary 1 and includes a silo buffer funnel body 6 that slides longitudinally at the upper part of the inner cavity of the granary 1, a valve plate 17 that is adapted to be installed in the feed port 18 at the bottom end of the silo buffer funnel body 6, and an elastic support component arranged on the bottom surface of the valve plate 17 to open the valve plate 17 due to the dead weight of grain entering the silo. The elastic support component includes two tension springs 20 and a positioning rod 31 that are symmetrically connected between the valve plate 17 and the feed port 18. Four extended support ear plates 19 are welded to the inner wall of the feed port 18 in an annular array. Two tension springs 20 are symmetrically installed on the top surfaces of two opposite extended support ear plates 19. The top ends of the tension springs 20 are fixedly connected to the bottom surface of the valve plate 17. The two positioning rods 31 both longitudinally penetrate the other two opposite extended support ear plates 19. The top ends of the positioning rods 31 are welded to the bottom surface of the valve plate 17 to provide the lifting, opening and closing positioning of the valve plate 17.

[0045] Specifically, the function of the silo buffer funnel 6 is to provide a preliminary buffer area when the grain enters the silo 1 from above, guide the grain to be evenly distributed through the funnel shape, slow down the falling speed, and reduce the damage caused by direct impact. The function of guiding the grain flow and primary deceleration is realized, and the effect is to initially reduce the impact force of the free fall of the grain. The valve plate 17 is controlled to open and close by the tension spring 20, and the feed flow rate is automatically adjusted. It automatically opens as the weight of the grain increases, realizing the flow control and dynamic buffering of the grain falling and grain entering the silo, and reducing the damage caused by direct impact of the grain. The tension spring 20 is installed between the extended support ear plate 19 of the feed port 18 and the valve plate 17, and automatically adjusts the opening according to the weight of the grain, providing buffering force, elastic support and automatic adjustment, ensuring that the valve plate 17 is opened in time, reducing the force of direct impact of the grain, and reducing damage.

[0046] Specifically, the second silo anti-crushing assembly 16 is arranged at the lower part of the inner cavity of the granary 1 and includes an anti-crushing receiving tube 12 fixedly installed at the lower part of the inner cavity of the granary 1, a rotating feeding cone cover 13 connected to the anti-crushing receiving tube 12 through a servo motor 25, and a rotating shaft 15 longitudinally penetrating and fixed on the top surface of the rotating feeding cone cover 13, the output shaft of the servo motor 25 is connected to the bottom end of the rotating shaft 15 through a reducer, and the top end of the rotating shaft 15 is connected to the valve plate 17 through a bearing, the bottom surface of the anti-crushing receiving tube 12 is integrally connected with a feeding funnel 22, and the inner bottom wall of the anti-crushing receiving tube 12 and the peripheral side above the feeding funnel 22 are provided with a material for preventing grain from being crushed when it rotates into the silo due to centrifugal force The buffer airbag component 30 includes a lateral receiving buffer portion 14 and a bottom receiving buffer portion 23 integrally connected to the bottom of the lateral receiving buffer portion 14. The outer wall of the lateral receiving buffer portion 14 elastically abuts against the inner wall of the anti-crushing receiving tube 12 and the lateral receiving buffer portion 14 is located at the circumferential side of the rotary feeding cone cover 13 to receive the grain thrown out from the outer wall of the rotary feeding cone cover 13 due to the centrifugal rotation force. The bottom receiving buffer portion 23 is located below the rotary feeding cone cover 13 to receive the grain bounced off the lateral receiving buffer portion 14 and fall into the feeding funnel 22. The top end of the rotary feeding cone cover 13 is higher than the bottom end of the rotary feeding cone cover 13.

[0047] Specifically, the anti-crushing receiving tube 12 is located at the lower part of the granary 1, and has a built-in rotary feeding cone cover 13. By receiving the grain thrown out by the rotary feeding cone cover 13, the impact force of the grain falling is further dispersed, the dispersion degree during the falling process is increased, and the local impact strength is reduced. The rotary feeding cone cover 13 is driven to rotate by the servo motor 25, and the grain is dispersed and slowly thrown down by centrifugal force, which significantly reduces the impact caused by vertical falling, realizes uniform dispersion and buffering of grain, and the effect is to greatly reduce grain damage.

[0048] Specifically, the lateral receiving buffer portion 14, as a part of the buffer airbag component 30, is installed on the inner side of the anti-crushing receiving tube 12. The lateral receiving buffer portion 14 laterally receives the grain thrown out by the rotary feeding cone cover 13, provides lateral buffering, absorbs impact laterally, and further disperses and alleviates the impact force of the grain. The bottom receiving buffer portion 23, as a part of the buffer airbag component 30, is located below the lateral receiving buffer portion 14. The bottom receiving buffer portion 23 receives the grain bounced from the top, further slows down the falling speed of the grain, protects the grain from impact damage, reduces the impact force at the final landing, and improves the integrity of the grain.

[0049] Specifically, the outer wall of the rotating shaft 15 at one end of the feed inlet 18 is symmetrically welded with a plurality of anti-blocking stirring blades 21 for preventing grain from falling and blocking. Two longitudinal chutes 9 are symmetrically opened on the upper inner wall of the granary 1. Two positioning sliders 11 are symmetrically welded on the outer wall of the buffer funnel 6 for entering the silo and slidingly connected with the longitudinal chutes 9. The buffer funnel 6 for entering the silo is positioned so as to be lowered due to the weight of the grain entering the silo.

[0050] Specifically, the longitudinal slide groove 9 is used in conjunction with the positioning slider 11 of the silo buffer funnel 6, allowing the silo buffer funnel 6 to slide up and down as the weight of the grain changes, automatically adjusting its position to adapt to different grain flow rates and quantities, achieving dynamic positioning, improving the adaptability and flexibility of the system, and better controlling the falling trajectory of the grain.

[0051] Specifically, the anti-clogging stirring blade 21 is welded to the outer wall of the rotating shaft 15, and prevents the grain from blocking the feed inlet 18 during the falling process through the rotational motion, thereby ensuring smooth flow of grain, improving the continuity and efficiency of feeding, and reducing interruptions in entering the warehouse due to blockage.

[0052] Specifically, the air pipe port 10 is connected to the peripheral side of the buffer airbag component 30, and the air pipe port 10 extends through the outside of the granary 1. The air pipe port 10 is connected to the buffer airbag component 30 to provide a passage for the airbag to be inflated, to ensure that the airbag maintains the required inflation state, to ensure the inflation and exhaust of the airbag, to enhance the buffering effect when the grain lands, and to reduce damage. A hemispherical cover 8 is integrally formed on the top surface of the valve plate 17 to prevent the grain from accumulating thereon. The hemispherical cover 8 is installed on the top of the valve plate 17 to prevent the grain from accumulating above the valve plate 17, to ensure the smooth passage of the grain, and to reduce the crushing that may be caused by the accumulation of grain on the top. Maintaining the passage unobstructed further reduces the pressure and damage caused by the accumulation of grain. A support plate 26 is welded between the inner walls of the feeding hopper 22, and the servo motor 25 is installed on the top surface of the support plate 26 by bolts. An installation receiving platform 24 is provided on the inner bottom wall of the anti-crushing receiving tube 12 for receiving and installing the bottom receiving buffer part 23.

[0053] Working principle:

[0054] The device for reducing grain crushing when entering the silo is that the grain is fed from the conveying equipment into the silo buffer funnel 6 above the silo 1, and the silo buffer funnel 6 guides the grain to fall evenly and slows down the grain falling speed through its own structure. The valve plate 17 in the first silo anti-crushing component 7 is located at the bottom of the silo buffer funnel 6, and the silo buffer funnel 6 is pressed by the grain's own weight. The silo buffer funnel 6 is pressed down by the grain's own weight, and the positioning slider 11 is driven to slide down in the silo buffer funnel 6. Since the longitudinal height of the rotating shaft 15 is fixed, when the silo buffer funnel 6 descends, the rotating shaft 15 The valve plate 17 is stretched upward and slowly opened by the tension spring 20. The opening size is automatically adjusted according to the weight of the grain to achieve the initial control of the grain flow rate. When the grain in the silo buffer funnel 6 falls below the pressure of the silo buffer funnel 6 (at this time, there is still a small amount of grain in the silo buffer funnel 6), the silo buffer funnel 6 slowly rises under the reaction contraction force of the tension spring 20, and the next dynamic flow control silo feeding operation is continued. By dynamically controlling the flow rate of the silo, the accumulation, collision and crushing of grain in the anti-crushing receiving tube 12 is reduced;

[0055] Once the grain falls into the granary 1 through the valve plate 17, the rotary feed cone hood 13 rotates under the drive of the servo motor 25, and the grain is evenly dispersed by centrifugal force, and gradually thrown to the bottom along the edge of the rotary feed cone hood 13, which greatly reduces the force of single-point impact. In this process, the lateral receiving buffer 14 in the anti-crushing receiving tube 12 laterally receives the grain thrown out by the rotary feed cone hood 13, provides lateral buffering, and absorbs impact laterally. The bottom receiving buffer 23 receives the grain that bounces off from the top, further slowing down the falling speed of the grain.

[0056] The grain eventually falls into the main body of the granary 1 through the discharge funnel 22, and the hydraulic buffer damper 28 at the bottom of the buffer support seat 2 absorbs the landing impact force to protect the grain and the granary structure.
