Description

Technical Field

[0001] This utility model relates to the field of fertilizer storage technology, and more specifically, to a moisture-proof and anti-caking multi-layer sealed fertilizer storage silo. Background Technology

[0002] Fertilizers play a vital role in modern agricultural production, and their quality directly affects crop growth and yield. Common fertilizer storage methods include warehouse stacking, simple shed storage, and various storage silos. Warehouse stacking is the most prevalent method, where fertilizer is stored in bags, but it is not efficient in utilizing warehouse space and is relatively inconvenient to manage. Simple shed storage is low-cost, but its protective capabilities are limited, providing only basic shade and rain protection. Storage silos are suitable for large-scale fertilizer storage, enabling a degree of centralized management and convenient access. However, traditional storage silos often use a simple single-layer sealing structure, typically sealing only the door with a single rubber strip. This sealing method is insufficient to effectively resist complex external environments. After long-term use, the rubber strips are prone to aging, deformation, and loss of elasticity, leading to decreased sealing performance. Moisture can easily penetrate the silo through these weak points. Damaged fertilizer not only loses nutrients but also changes its physical properties; originally loose particles become sticky, and in severe cases, large hard lumps form. To address the shortcomings of existing technologies, we propose a moisture-proof and anti-caking multi-layer sealed fertilizer storage silo. Utility Model Content

[0003] To overcome the aforementioned defects of the prior art, this utility model provides a multi-layer sealed fertilizer storage silo that is moisture-proof and anti-caking. This solves the problem that single-layer rubber strip sealing is difficult to effectively resist complex external environments. After long-term use, rubber strips are prone to aging, deformation, and loss of elasticity, resulting in a decline in sealing performance. Moisture can easily penetrate into the silo from these weak points. When fertilizer gets damp, not only are nutrients lost, but its physical properties also change. The originally loose particles become sticky, and in severe cases, large hard lumps can form.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a moisture-proof and anti-caking multi-layer sealed fertilizer storage silo, including a silo body, wherein a multi-layer sealing assembly for feeding is provided on the upper side of the silo body, and a multi-layer sealing assembly for discharging is provided on one side of the silo body;

[0005] The multi-layer sealing assembly for feeding includes a base ring. A track plate is symmetrically fixedly installed on the upper outer surface of the base ring. A track groove is formed on the surface of the track plate. A cover plate is slidably attached to the side of the track plate. A connecting column is symmetrically fixedly installed on the side of the cover plate. A U-shaped frame is fixedly installed at one end of the connecting column. A wheel is rotatably connected to the inner surface of the U-shaped frame. An electric telescopic rod is fixedly installed on the side of the wheel. A mounting base is fixedly installed at the bottom end of the electric telescopic rod. A first frustum string is fixedly installed on the lower surface of the cover plate. A feeding sealing ring is attached to the side of the first frustum string.

[0006] The base ring is fixedly installed on the upper outer wall of the hopper body, the cover plate is attached to the top of the hopper body, the connecting column slides on the outer wall of the track groove, the mounting seat is rotatably connected to the side of the base ring, and the feed sealing ring is set on the upper inner wall of the hopper body.

[0007] The discharge multi-layer sealing assembly includes a discharge cylinder, an inner wall of which is provided with a discharge sealing ring, a second frustum string attached to the surface of the discharge sealing ring, a cover plate two fixedly installed at one end of the second frustum string, a T-shaped handle fixedly installed on one outer surface of the cover plate two, a positioning hole opened on the side of the cover plate two, a fixing frame fixedly installed on the upper outer wall of the discharge cylinder, a spring fixedly installed at the top of the inner cavity of the fixing frame, a positioning post fixedly installed at the bottom end of the spring, the discharge cylinder fixedly installed on the side of the hopper, the cover plate two sliding on the inner surface of the discharge cylinder, and the positioning post sliding on the outer wall of the positioning hole, the inner surface of the fixing frame, and the inner wall of the discharge cylinder.

[0008] The first and second frustum strings are each composed of three frustums connected in series by a connecting shaft. The feed sealing ring and the discharge sealing ring are each provided with three layers. The frustum surfaces of the first and second frustum strings are pressed and bonded to the corresponding three layers of feed sealing ring and three layers of discharge sealing ring.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] This utility model utilizes a multi-layer sealing assembly for feeding, including a base ring. Activating the electric telescopic rod pushes the rotating wheel, causing the U-shaped frame to move upwards. This allows the connecting column to slide on the outer wall of the track groove, simultaneously moving the cover plate and causing the first frustum string to move away from the upper side of the silo. At this point, fertilizer is poured into the silo from the top. Activating the electric telescopic rod resets the first frustum string, causing it to press against the three-layer feeding sealing rings on the inner surface of the upper side of the silo. Using this structure, by activating the electric telescopic rod and simultaneously pressing against the three layers of feeding sealing rings, multi-layer sealing of the silo's feed inlet is achieved, greatly improving the silo's sealing performance, reducing the probability of fertilizer becoming damp and clumping, and ensuring the normal use of the fertilizer.

[0011] This invention utilizes a multi-layer sealing assembly for material discharge, including a discharge cylinder. By holding a T-shaped handle, the second frustum string is inserted into the discharge cylinder, causing the second cover plate to slide on the inner surface of the discharge cylinder. This pushes the positioning pin to slide on the inner surface of the fixing frame, compressing the spring. When the positioning pin reaches the positioning hole, the spring resets, causing the positioning pin to insert into the outer wall of the positioning hole. At this time, the second frustum string compresses the three-layer discharge sealing ring set on the inner surface of the discharge cylinder. Using the above structure, the sealing performance inside the hopper is further improved through the second frustum string and the discharge sealing rings. At the same time, the cooperation of the spring and the positioning pin facilitates the opening and closing of the second cover plate. Attached Figure Description

A track groove 23 is opened on the surface of the track plate 22. A cover plate 24 is slidably attached to the side of the track plate 22. A connecting column 25 is symmetrically fixedly installed on the side of the cover plate 24. A U-shaped frame 26 is fixedly installed at one end of the connecting column 25. A rotating wheel 27 is rotatably connected to the inner surface of the U-shaped frame 26. An electric telescopic rod 28 is fixedly installed on the side of the rotating wheel 27. A mounting seat 29 is fixedly installed at the bottom end of the electric telescopic rod 28. A first frustum string 211 is fixedly installed on the lower surface of the cover plate 24. A feeding sealing ring 212 is attached to the side of the first frustum string 211.

[0020] Among them, the base ring 21 is fixedly installed on the upper outer wall of the hopper body 1, the cover plate 24 is attached to the top of the hopper body 1, the connecting column 25 slides on the outer wall of the track groove 23, the mounting seat 29 is rotatably connected to the side of the base ring 21, and the feed sealing ring 212 is set on the upper inner wall of the hopper body 1.

[0021] By activating the electric telescopic rod 28, the first frustum string 211 is driven to simultaneously compress the three layers of feed sealing rings 212, thereby achieving multi-layer sealing of the feed inlet of the silo 1, greatly improving the sealing performance of the silo 1, reducing the probability of fertilizer becoming damp and clumping, and ensuring the normal use of the fertilizer.

[0022] The discharge multi-layer sealing assembly 3 includes a discharge cylinder 31, an discharge sealing ring 32 on the inner wall of the discharge cylinder 31, a second frustum string 33 attached to the surface of the discharge sealing ring 32, a cover plate 34 fixedly installed at one end of the second frustum string 33, a T-shaped handle 35 fixedly installed on one side of the outer surface of the cover plate 34, a positioning hole 36 opened on the side of the cover plate 34, a fixing frame 37 fixedly installed on the upper outer wall of the discharge cylinder 31, a spring 38 fixedly installed at the top of the inner cavity of the fixing frame 37, a positioning post 39 fixedly installed at the bottom end of the spring 38, the discharge cylinder 31 fixedly installed on the side of the hopper 1, the cover plate 34 sliding on the inner surface of the discharge cylinder 31, and the positioning post 39 sliding on the outer wall of the positioning hole 36, the inner surface of the fixing frame 37, and the inner wall of the discharge cylinder 31.

[0023] The second frustum string 33 and the discharge sealing ring 32 further improve the sealing performance inside the hopper 1. At the same time, the cooperation of the spring 38 and the positioning column 39 facilitates the opening and closing of the cover plate 34.

[0024] The first frustum string 211 and the second frustum string 33 are both composed of three frustums connected in series by a connecting shaft. The feed sealing ring 212 and the discharge sealing ring 32 are both provided with three layers. The frustum surfaces of the first frustum string 211 and the second frustum string 33 are pressed and adhered to the corresponding three layers of feed sealing ring 212 and three layers of discharge sealing ring 32.

[0025] The working process of this utility model is as follows:

[0026] The electric telescopic rod 28 is activated, pushing the rotating wheel 27 to drive the U-shaped frame 26 upward, causing the connecting column 25 to slide on the outer wall of the track groove 23, thereby driving the cover plate 24 to move synchronously, causing the first frustum string 211 to leave the upper side of the silo body 1. At this time, fertilizer is poured from the upper end of the silo body 1 into the interior of the silo body 1. The electric telescopic rod 28 is activated again to reset, causing the first frustum string 211 to reset. At this time, the first frustum string 211 squeezes the three-layer feed sealing ring 212 set on the upper inner surface of the silo body 1, realizing multi-layer sealing of the feed inlet of the silo body 1 and improving the sealing performance of the silo body 1.

[0027] Holding the T-shaped handle 35, insert the second frustum string 33 into the inside of the discharge cylinder 31, so that the cover plate 34 slides on the inner surface of the discharge cylinder 31, pushing the positioning pin 39 to slide on the inner surface of the fixing frame 37 and compress the spring 38. When the positioning pin 39 reaches the positioning hole 36, the spring 38 resets and drives the positioning pin 39 to insert into the outer wall of the positioning hole 36. At this time, the second frustum string 33 compresses the three-layer discharge sealing ring 32 set on the inner surface of the discharge cylinder 31, further improving the sealing performance inside the hopper 1. At the same time, the cooperation of the spring 38 and the positioning pin 39 facilitates the opening and closing of the cover plate 34.
