Description

Technical Field

[0001] The invention belongs to the technical field of fertilizer storage, in particular to a storage device for fertilizer production and capable of preventing fertilizer from caking. Background Art

[0002] Fertilizers are important substances for improving soil fertility and promoting crop growth, and are widely used in various farmlands. However, fertilizers are prone to caking during storage. Caked fertilizers are not only difficult to spread evenly, but also may cause the loss or change of their effective ingredients due to excessive moisture content or improper storage conditions, thus affecting their application effect, reducing the growth of crops, and even causing certain negative impacts on the environment.

[0003] A Chinese patent application CN112722539A discloses a storage device for fertilizer production that can prevent fertilizer from agglomerating. The key points of the technical solution are: it includes a tank body, one side of the tank body is provided with an adjustment groove, the top of the tank body is provided with a limit slide groove, and the bottom of the tank body is provided with two groups of material guide ports. The storage device for fertilizer production that can prevent fertilizer from agglomerating provided by this technology can store two different fertilizers at the same time, and the top of the partition plate is in conflict with the bottom of the linkage disk and is movably connected, so that the fertilizers on both sides of the partition plate do not interfere with each other, ensuring the stability of storing two different fertilizers at the same time, and the two groups of air inlet boxes are adapted to the two groups of material guide ports, so as to facilitate the simultaneous exhaust cooling and drying treatment of both sides of the partition plate to prevent impurities from entering the interior of the tank body through the material guide port and affecting the quality of the fertilizer, and the partition net is used to support the fertilizer to prevent the fertilizer from falling from the partition net.

If the fertilizer is affected by moisture and forms agglomerates, then during the tumbling movement of the fertilizer inside the storage barrel, part of the fertilizer compacted on the inner wall of the storage barrel will be scraped off by the scraper when it rotates to the top, and then the scraped fertilizer block will fall downward to the surface of other fertilizers, forming a falling impact effect, which is conducive to breaking up the agglomerated fertilizer, and the compacted fertilizer in the middle of the storage barrel will be cut by the grid plate during movement, thereby gradually cutting and crushing the fertilizer to a normal particle size, thereby improving the anti-caking effect of the fertilizer storage device.

[0019] 3. The present invention discloses a storage device for fertilizer production that prevents fertilizer from caking. When the driving mechanism is in operation, the pulley rotates and uses the connecting rod to drive the lifting plate to continuously reciprocate up and down inside the conveying cylinder. When the lifting plate moves upward, the outside air is sucked into the conveying cylinder through the air inlet pipe. When the lifting plate moves downward, the air inside the conveying cylinder is squeezed into each fixed rod through the air outlet pipe, and then the air is discharged into the storage barrel through the air guide pipe and the air hole. As the fertilizer rolls inside the storage barrel, the gap increases, and the airflow is used to continuously carry away the moisture between the fertilizers through the air vents to the outside, thereby reducing the moisture inside the storage barrel and further reducing the problem of fertilizer agglomeration.

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0024] like Figures 1 to 7 As shown, a fertilizer production storage device for preventing fertilizer from agglomerating according to the present invention comprises an outer frame 1 and a driving mechanism; The outer frame 1 is internally rotatably connected with a storage barrel 2; both ends of the storage barrel 2 are open, and both ends are rotatably connected to the outer frame 1 and blocked by the outer frame 1; the driving mechanism is used to control the storage barrel 2 to rotate inside the outer frame 1; A feed port 3 and a discharge port 4 are provided on one side of the outer frame 1, and both the feed port 3 and the discharge port 4 are connected to the storage barrel 2; It also includes a clumping cutting mechanism; the clumping cutting mechanism is arranged inside the storage barrel 2 and is used to cut and crush the clumped fertilizer; The agglomeration cutting mechanism includes a scraper 5 and a fixed rod 6, and both ends of the scraper 5 and the fixed rod 6 are fixedly connected to the outer frame 1; the scraper 5 is arranged on the top of the storage barrel 2 and fits against the inner wall of the storage barrel 2; the fixed rod 6 is provided with a group and is evenly distributed inside the storage barrel 2; the surface of the fixed rod 6 is provided with an arc frame 7; a mesh plate 8 is fixedly connected inside the arc frame 7, and the pores of the mesh plate 8 are larger than the fertilizer particles.

[0025] The driving mechanism includes an electric motor 9 installed on one side of the outer frame 1; an annular gear ring 10 is fixedly connected to the outer side of the storage barrel 2; the electric motor 9 and the annular gear ring 10 are connected to each other through a pulley 11, a belt 12, a pulley 2 13, and a gear 14 in sequence, the pulley 11 is connected to the output shaft of the electric motor 9, the belt 12 is sleeved on the surfaces of the pulley 11 and the pulley 2 13, the pulley 2 13 and the gear 14 are connected through a shaft, and the gear 14 and the annular gear ring 10 are meshed with each other.

[0026] The fertilizer storage device in the prior art adopts an exhaust method to prevent the fertilizer from getting damp and agglomerating. However, the exhaust conduit is difficult to be evenly arranged at each position in the device, and the fertilizers are squeezed and piled up on each other with small gaps, which makes it difficult to fully extract the moisture between the fertilizers. In addition, the fertilizers inside the device are always in a stationary state during the storage process, and are not only prone to agglomeration under the action of moisture, but the fertilizers at the bottom of the device will also become compacted under the pressure of gravity. Therefore, the anti-caking effect of the storage device is not good, and the storage quality of the fertilizer is low.

[0027] The present invention stores the fertilizer inside a horizontally placed storage barrel 2. During the storage process, the storage barrel 2 is controlled to rotate slowly by a driving mechanism at regular intervals, so that the fertilizer is constantly rolled inside the storage barrel 2, and the spatial position of the fertilizer is changed, which can reduce the agglomeration conditions and tendencies of the fertilizer, and effectively alleviate the problem that the fertilizer is always in a static state and becomes hardened into agglomerates under the action of moisture and gravity.

[0028] By setting up a clumping cutting mechanism, if the fertilizer is affected by moisture and forms lumps, during the rolling movement of the fertilizer inside the storage barrel 2, part of the fertilizer compacted on the inner wall of the storage barrel 2 will be scraped off by the scraper 5 when it rotates to the top, and then the scraped lumpy fertilizer falls downward to the surface of other fertilizers, forming a falling impact effect, which is conducive to breaking up the clumped fertilizer, and the compacted fertilizer in the middle of the storage barrel 2 will be cut by the grid plate 8 during movement, thereby gradually cutting and crushing the fertilizer to a normal particle size, thereby improving the anti-caking effect of the fertilizer storage device.

[0029] It is worth noting that the fertilizer stored in the storage barrel 2 is not easy to be overfilled, and a certain space should be reserved at the top of the storage barrel 2. Therefore, when the fertilizer moves to the top, it tends to fall downward, so that it can form a collision effect with the fertilizer below, which is beneficial to improve the crushing and dispersion efficiency of the agglomerated fertilizer.

[0030] As a preferred embodiment of the present invention, a support foot 15 is fixedly connected to the bottom of one side of the outer frame 1; a support frame 16 is fixedly connected to both sides of the other side of the outer frame 1; a telescopic cylinder 17 is arranged between the support frame 16 and the ground, and the telescopic cylinder 17 can be driven by electric, pneumatic or hydraulic means. By arranging the support foot 15 and the telescopic cylinder 17, in the loading stage, the telescopic cylinder 17 is controlled to be shortened, and the outer frame 1 and the storage barrel 2 are tilted toward the telescopic cylinder 17, which makes it convenient to add fertilizer into the storage barrel 2 through the feed port 3. In the discharging stage, the telescopic cylinder 17 is controlled to be extended, and the outer frame 1 and the storage barrel 2 are tilted toward the support foot 15. At this time, the storage barrel 2 is controlled to rotate by the driving mechanism, and the fertilizer inside the storage barrel 2 can be gradually discharged automatically through the discharge port 4.

[0031] As a preferred embodiment of the present invention, the fixing rods 6 are designed as hollow tubular structures; a group of air guide tubes 18 are evenly distributed on the surface of the fixing rods 6; air holes 19 are arranged on the surface of the air guide tubes 18; a vent 20 is arranged on one side of the outer frame 1, and the vent 20 is connected to the storage barrel 2; A conveying cylinder 21 is fixedly connected to the surface of the outer frame 1 at the position corresponding to the pulley 11; a lifting plate 22 is slidably and sealedly connected inside the conveying cylinder 21; a connecting rod 23 is hinged between the edge of the pulley 11 and the lifting plate 22; the bottom of the conveying cylinder 21 is connected to the fixed rod 6 through an air outlet pipe 24; the bottom of the conveying cylinder 21 is connected to an air inlet pipe 25; and one-way valves are arranged inside the air vent 20, the air inlet pipe 25, and the air outlet pipe 24.

[0032] When the driving mechanism is running, the pulley 11 rotates and uses the connecting rod 23 to drive the lifting plate 22 to continuously reciprocate up and down inside the conveying cylinder 21. When the lifting plate 22 moves upward, the outside air is sucked into the conveying cylinder 21 through the air inlet pipe 25. When the lifting plate 22 moves downward, the air inside the conveying cylinder 21 is squeezed into each fixed rod 6 through the air outlet pipe 24, and then the air is discharged into the storage barrel 2 through the air guide pipe 18 and the air hole 19. As the fertilizer rolls inside the storage barrel 2, the gap increases, and the air flow is used to continuously take away the moisture between the fertilizers through the air vent 20 to the outside, thereby reducing the humidity inside the storage barrel 2 and further reducing the problem of fertilizer agglomeration.

[0033] The air inlet pipe 25 is connected to a drying box 26; an air filter assembly and a desiccant are arranged inside the drying box 26. The air filter assembly is used to remove dust and other impurities in the air, and the desiccant is used to remove moisture in the air to prevent impurities and moisture from entering the storage barrel 2. The air filter assembly can be a filter, filter cotton, activated carbon, etc., or a combination thereof; the desiccant can be quicklime, charcoal, montmorillonite, etc., or a combination thereof.

[0034] A guide rod 27 is slidably and sealably connected inside the air guide tube 18 ; one end of the guide rod 27 is fixedly connected to the arc frame 7 , and the other end is fixedly connected to the fixed rod 6 by an elastic strip 28 . When the compressed air in the conveying cylinder 21 enters the interior of the fixed rod 6 through the air outlet pipe 24, it will first push the guide rod 27 to slide outward inside the air guide pipe 18. After the tail end of the guide rod 27 passes over the air hole 19, the air can be discharged outward through the air hole 19. When the lifting plate 22 moves upward, the elastic strip 28 pulls the guide rod 27 to move toward the fixed rod 6 to reset and re-block the air hole 19. Through this structure, on the one hand, the air hole 19 can be closed when there is no ventilation to prevent fertilizer from entering the air guide pipe 18 and the interior of the fixed rod 6 through the air hole 19. On the other hand, when the guide rod 27 reciprocates, it drives the arc frame 7 and the grid plate 8 to move synchronously, thereby further cutting and crushing the compacted fertilizer inside the storage barrel 2. In addition, the compacted fertilizer scraped off by the scraper 5 moves toward the surface of a grid plate 8 at the top when falling downward, and the grid plate 8 moves upward in the opposite direction of the falling direction of the fertilizer. The two form a counter-impact and collision effect, which can improve the impact and dispersion effect on the block fertilizer.

[0035] As a preferred embodiment of the present invention, a group of slag outlets 29 are evenly distributed on the surface of the storage barrel 2; an isolation cover 30 is arranged inside the storage barrel 2 at a position corresponding to the slag outlet 29; a group of sieves 31 are evenly distributed on the surface of the isolation cover 30, and the pores of the sieves 31 are smaller than the fertilizer particles; and a collecting dish 32 is arranged under the storage barrel 2.

[0036] The fertilizer inside the storage barrel 2 is prone to produce many small fertilizer fragments under long-term heavy pressure, and the fertilizer after agglomeration has absorbed water, and the internal structure has been softened and reorganized, so it is easy to form a lot of powdered fertilizers after cutting and crushing. These fine fertilizers are smaller than the normal particle size, which will affect the appearance and reduce the fertilizer efficiency during use. Therefore, the prior art usually tends to remove this part of the fertilizer. When the fertilizer in the storage barrel 2 of the present invention rolls, the fine fertilizer inside it will gradually pass through the screen 31 into the isolation cover 30, while the fertilizer of normal particle size cannot pass through the screen 31. When the isolation cover 30 rotates to the bottom, the fine fertilizer inside it can be discharged into the collection dish 32 through the slag outlet 29, so that the unqualified fertilizer inside the storage barrel 2 is removed and collected to prevent it from affecting the quality of the fertilizer product.

[0037] A weight ball 33 is arranged outside the slag outlet 29; a spring 1 34 is fixedly connected between the weight ball 33 and the slag outlet 29. When the slag outlet 29 is located in the middle and upper part of the storage barrel 2, under the tensile effect of the spring 1 34, the weight ball 33 fits the outside of the slag outlet 29 and blocks it, preventing the fertilizer powder inside the isolation cover 30 from flying out through the slag outlet 29. When the slag outlet 29 rotates to the bottom, the gravity of the weight ball 33 overcomes the tension of the spring 1 34, causing a gap to be generated between the weight ball 33 and the slag outlet 29, so that the unqualified fertilizer inside the isolation cover 30 can fall into the collection dish 32 through the gap.

[0038] As a preferred embodiment of the present invention, a mounting plate is fixedly connected inside the isolation cover 30; a movable block 35 is arranged on one side of the mounting plate close to the isolation cover 30; a spring 2 36 is fixedly connected between the movable block 35 and the mounting plate; a group of magnetic rods 37 are evenly distributed inside the collection dish 32, and the magnetic rods 37 and the movable block 35 attract each other when they are close. When the isolation cover 30 rotates to the bottom, it intermittently approaches and moves away from each magnetic rod 37, and when the movable block 35 approaches the magnetic rod 37, it will be attracted by it, and then the movable block 35 moves back to the isolation cover 30 and compresses the spring 2 36, and when the movable block 35 moves away from the magnetic rod 37, the spring 2 36 pushes the movable block 35 to hit the isolation cover 30, and the isolation cover 30 is used to drive the fertilizer around it to shake, and promote the debris between the fertilizer gaps to enter the isolation cover 30 through the screen 31, thereby improving the concentration efficiency of the finely crushed fertilizer, which is conducive to the full discharge of the finely crushed fertilizer through the slag outlet 29.

[0039] The inner wall of the storage barrel 2 is fixedly connected with a jacket 38 at a position corresponding to the isolation cover 30; a coupling plate 39 is fixedly connected with the edge of the isolation cover 30, and the coupling plate 39 is slidably connected to the inside of the jacket 38; and an elastic strip 2 40 is fixedly connected between the coupling plate 39 and the jacket 38. By providing the jacket 38, the coupling plate 39 and the elastic strip 2 40, when the movable block 35 hits the isolation cover 30, the coupling plate 39 can slide inside the jacket 38, and under the elastic action of the elastic strip 2 40, the shaking and shaking effect of the isolation cover 30 is improved, and the crushed fertilizer enters the isolation cover 30 more quickly.

Figure 1 As a benchmark, according to the person's observation perspective, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
