Description

Technical Field

[0001] The invention relates to the technical field of fertilizer preparation, and in particular to a shearing machine for preparing water-soluble fertilizer containing seaweed and a use method thereof. Background Art

[0002] Water Soluble Fertilizer (WSF) is a multi-component compound fertilizer that can be completely soluble in water. It can dissolve quickly in water and is more easily absorbed by crops. Its absorption and utilization rate is relatively high. More importantly, it can be used in facility agriculture such as sprinkler and drip irrigation to achieve water-fertilizer integration and save water, fertilizer and labor. When preparing water-soluble fertilizers, seaweed will be filled inside the water-soluble fertilizers, but the seaweed particles are large. When producing and preparing seaweed water-soluble fertilizers, shearing equipment is required to shear the seaweed.

[0003] For example, the Chinese patent publication number CN220238760U discloses a shearing machine for preparing water-soluble fertilizer containing seaweed, comprising a seaweed crushing box body, a seaweed limiting plate fixedly connected to one side of the lower part of the seaweed crushing box body, a seaweed cutting and collecting plate fixedly connected to the outside of the seaweed limiting plate, a crushing knife installed at the upper end of the interior of the seaweed crushing box body, and a spiral conveying pipe installed at the lower part of the crushing knife. The shearing machine for preparing water-soluble fertilizer containing seaweed, after the seaweed is sheared by the shearing knife, is transported to the interior of the seaweed cutting and collecting plate, while a recycling pipe is installed at the rear end of the seaweed cutting and collecting plate, and the recycling pipe drives the sheared seaweed to be collected and transported to the interior of the seaweed crushing box body, that is, the seaweed can be continuously sheared inside the seaweed crushing box body and the seaweed limiting plate, thereby increasing the crushing efficiency of the seaweed and facilitating the uniformity of mixing during the later production and preparation of the water-soluble fertilizer containing seaweed.

[0004] Currently, a shearing machine for preparing water-soluble fertilizer containing seaweed still has some shortcomings. For example, the fixed-position blade can only shear seaweed at a specific height, resulting in inconsistent seaweed processing at different height layers in the tank. The upper seaweed may retain large particles due to insufficient contact with the blade, while the lower seaweed may be over-sheared, resulting in energy waste. The final product has an uneven particle size distribution, which affects the dissolution rate of the fertilizer and the stability of nutrient release, thereby reducing product quality. Summary of the Invention

[0005] In view of the deficiencies in the prior art, the present invention provides a shearing machine for preparing water-soluble fertilizer containing seaweed and a method for using the same, which solves the problems mentioned in the background art.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A shearing machine for preparing water-soluble fertilizer containing seaweed and a method for using the same, comprising: a base, a shearing tank fixedly mounted on the top surface of the base, a feed pipe provided on the top surface of the shearing tank, a feed hopper provided on the external fixed sleeve of the feed pipe, two rotating holes provided on the top surface of the shearing tank, a rotating column provided inside the rotating hole, two rotating shafts provided inside the shearing tank, a plurality of shearing blades fixedly mounted on the outer circular wall surface of the rotating shaft, a mounting frame fixedly mounted on the top surface of the shearing tank, a first drive motor fixedly mounted on the top surface of the mounting frame, the shaft of the first drive motor and one of the rotating columns; a telescopic assembly, the telescopic assembly provided on the top surface of the rotating shaft for adjusting the shearing depth of the shearing blade, the telescopic assembly comprising a support The support plate is fixedly mounted on the inner circular wall surface of the shearing tank, the support plate is movably sleeved together with the rotating shaft, a connecting cylinder is provided on the outside of the rotating shaft, the connecting cylinder is movably mounted together with the rotating shaft, a first electromagnet is fixedly mounted on the inner top surface of the connecting cylinder, a second electromagnet is fixedly mounted on the top surface of the rotating shaft, a spring is provided on the outside of the rotating shaft, when in use, the first electromagnet and the second electromagnet are turned on, the two electromagnets are of the same name, when powered on, the magnetic force generated repels each other, causing the second electromagnet to drive the rotating shaft to move downward, squeezing the spring while moving, and when the first electromagnet and the second electromagnet are closed, the compressed force of the spring is released to drive the rotating shaft to rise, so that the shear blade can cut the seaweed raw materials at different positions inside the shearing tank.

[0008] By adopting the above technical solution,

[0009] By setting a telescopic component, the seaweed raw material enters the feed pipe through the feed hopper, and then falls into the shearing tank from the feed pipe to prepare the material for shearing. The first drive motor is started, and the shear blade on the rotating shaft rotates with the rotating shaft to shear the seaweed raw material falling into the shearing tank, and shears the larger particles of seaweed into smaller particles or fragments. By controlling the power supply of the first electromagnet and the second electromagnet, the magnetic force between the two can be changed. When the magnetic force changes, a downward force is applied to the rotating shaft, and the spring is squeezed while moving. After the power supply of the electromagnet is turned off, the spring releases the compressed potential energy, pushing the rotating shaft to reset upward, and the shear blade is lifted accordingly, which can shear the upper layer of raw materials in the shearing tank. By repeatedly controlling the on and off of the electromagnet, the shear blade can realize reciprocating motion in the vertical direction to cover raw materials at different heights. The shear blade can move up and down in the shearing tank, and can dynamically cut seaweed raw materials at different positions without stopping, avoiding insufficient shearing of local raw materials and improving shearing uniformity.

[0010] Preferably, the shear blades are in the form of a matrix of upper and lower staggered blades.

[0011] By adopting the above technical solution and setting shear blades, the lower two layers of staggered blade matrices can promptly shear the seaweed wrapped around the rotating shaft, effectively preventing a large amount of seaweed from being entangled and causing the rotating shaft to be obstructed or even stopped, thereby reducing the probability of equipment failure, ensuring the continuity of the preparation process of the water-soluble fertilizer containing seaweed, and reducing the downtime maintenance costs and production delay losses caused by equipment failure.

[0012] Preferably, the shaft of the first drive motor and the external fixed sleeve of the rotating column are provided with a pulley, and a belt is provided on the outside of the pulley.

[0013] By adopting the above technical solution and setting a belt, when starting, the first drive motor starts to run, and its output shaft drives the fixed pulley to rotate. The friction between the pulley and the belt causes the belt to move accordingly, thereby driving the pulley outside the rotating column to rotate, and finally realizing the rotation of the rotating column. The belt transmission is elastic and can buffer the vibration and impact generated when the first drive motor is running, so that the rotation of the rotating column and the rotating shaft is smoother.

[0014] Preferably, a discharge pipe is provided on the bottom surface of the shear tank, a separation frame is fixedly installed inside the base, a filter screen is provided inside the separation frame, and a discharge port is opened on one side of the base.

[0015] By adopting the above technical solution and setting up a filter, after the seaweed raw material is fully sheared by the upper and lower layers of staggered blade matrices in the shearing tank, the sheared seaweed fragments fall from the discharge pipe at the bottom of the shearing tank due to gravity. The discharge pipe guides the seaweed fragments to the separation rack inside the base. The filter in the separation rack screens and separates the seaweed fragments. The fine seaweed particles that meet the particle size requirements pass through the filter and are discharged from the discharge port on one side of the base and enter the subsequent water-soluble fertilizer preparation process as qualified shearing products; while the seaweed fragments with larger particle size that do not pass through the filter are intercepted and slide to the other side. The seaweed fragments are screened by the filter, and the particle size of the discharged material can be accurately controlled to avoid affecting the dissolution effect and nutrient release of the subsequent water-soluble fertilizer due to uneven particle size of the fragments, thereby improving the quality and consistency of the final product.

[0016] Preferably, a return hole is opened on one side of the base, a return pipe is fixedly sleeved inside the return hole, a spiral conveying shaft is arranged inside the return pipe, a second drive motor is fixedly installed on the top surface of the return pipe, the shaft of the second drive motor is fixedly connected to the spiral conveying shaft, an inclined tube is arranged on the outer circular wall surface of the return tube, and the inclined tube is connected to the shear tank.

[0017] By adopting the above technical solution and setting a return pipe, when the filter screen in the separation frame intercepts the seaweed fragments with larger particle size and slides to the other side, the second drive motor is started and its shaft drives the spiral conveying shaft to rotate in the return pipe. The spiral conveying shaft transports the seaweed fragments accumulated at the return hole upward along the return pipe through the rotation of the spiral blades. As the fragments are lifted to the inclined tube position, under the combined action of the spiral thrust and gravity, the fragments re-enter the shear tank through the inclined tube. The seaweed fragments returning to the shear tank will be sheared again by the upper and lower layers of staggered blade matrices until their particle size meets the requirements. After screening through the discharge pipe and the filter screen, they are discharged from the discharge port. By continuously returning the large-particle fragments for shearing, the particle size of the finally discharged seaweed fragments is ensured to be uniform, avoiding the dissolution rate and nutrient release efficiency of the water-soluble fertilizer affected by insufficient shearing of some materials, thereby stabilizing and improving the product quality of the seaweed water-soluble fertilizer.

[0018] Preferably, a guide block is fixedly mounted on the bottom surface of the base.

[0019] By adopting the above technical solution and setting up a guide block, since the guide block fixedly installed on the bottom surface of the base is in the shape of an inclined block, under the action of gravity, the accumulated seaweed fragments will slide down the inclined surface of the guide block, automatically move toward the return hole, and finally enter the return hole, thereby reducing the risk of accumulation and blockage of the fragments in the base, allowing the material to enter the return system more smoothly and efficiently, thereby speeding up the entire circulation processing process.

[0020] Preferably, a solenoid valve is provided outside the discharge pipe.

[0021] By adopting the above technical solution and setting a solenoid valve, the solenoid valve can be quickly opened or closed by an electrical signal to realize the control of the output of the seaweed fragments in the discharge pipe.

[0022] Preferably, an observation window is provided on the outside of the shear tank.

[0023] By adopting the above technical solution and setting up an observation window, the operator does not need to open the shearing tank, but can visually view the shearing progress of the seaweed raw material, the operation status of the blade and the distribution status of the material in the tank through the observation window.

[0024] In summary, the present invention mainly has the following beneficial effects:

[0025] By setting a telescopic component, the seaweed raw material falls into the shearing tank through the feed hopper, and the material is prepared for the shearing work. The first drive motor is started, and the shear blade on the rotating shaft rotates with the rotating shaft to shear the seaweed raw material falling into the shearing tank, and the larger particles of seaweed are sheared into smaller particles or fragments. By controlling the power supply of the first electromagnet and the second electromagnet, the magnetic force between the two can be changed. When the magnetic force changes, a downward force is applied to the rotating shaft, and the spring is squeezed while moving. After the power supply of the electromagnet is turned off, the spring releases the compressed potential energy, pushing the rotating shaft to reset upward, and the shear blade is lifted accordingly, which can shear the upper layer of raw materials in the shearing tank. By repeatedly controlling the on and off of the electromagnet, the shear blade can realize reciprocating motion in the vertical direction to cover raw materials at different heights. The shear blade can move up and down in the shearing tank, and seaweed raw materials at different positions can be dynamically cut without stopping, avoiding insufficient shearing of local raw materials and improving shearing uniformity.

[0026] By setting up a return pipe, when the filter screen in the separation frame intercepts seaweed fragments with larger particle size and slides to the other side, the second drive motor is started at this time, and its shaft drives the spiral conveying shaft to rotate in the return pipe. The spiral conveying shaft transports the seaweed fragments accumulated at the return hole upward along the return pipe through the rotation of the spiral blades. As the fragments are lifted to the inclined tube position, under the combined action of spiral thrust and gravity, the fragments re-enter the shear tank through the inclined tube. The seaweed fragments returning to the shear tank will be sheared again by the upper and lower layers of staggered blade matrices until their particle size meets the requirements. After screening through the discharge pipe and filter screen, they are discharged from the discharge port. By continuously returning the large-size fragments for shearing, the particle size of the finally discharged seaweed fragments is guaranteed to be uniform, avoiding the dissolution rate and nutrient release efficiency of the water-soluble fertilizer due to insufficient shearing of some materials, thereby stabilizing and improving the product quality of the seaweed water-soluble fertilizer.

DETAILED DESCRIPTION

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] refer to Figures 1-6 , a shearing machine for preparing water-soluble fertilizer containing seaweed and a method of use, comprising: a base 1, a shearing tank 2 is fixedly installed on the top surface of the base 1, a feed pipe 3 is provided on the top surface of the shearing tank 2, a feed hopper 4 is fixedly sleeved on the outside of the feed pipe 3, two rotating holes 5 are provided on the top surface of the shearing tank 2, a rotating column 12 is provided inside the rotating hole 5, two rotating shafts 7 are provided inside the shearing tank 2, a plurality of shearing blades 9 are fixedly installed on the outer circular wall surface of the rotating shaft 7, a mounting frame 10 is fixedly installed on the top surface of the shearing tank 2, a first driving motor 11 is fixedly installed on the top surface of the mounting frame 10, and the shaft of the first driving motor 11 is connected to one of the rotating columns 12; a telescopic component, the telescopic component is provided on the top surface of the rotating shaft 7, and is used to adjust the shearing depth of the shearing blade 9, the telescopic component comprises a support plate 8, and the support plate 8 is fixedly installed On the inner circular wall surface of the shearing tank 2, the support plate 8 and the rotating shaft 7 are movably sleeved together, and a connecting cylinder 13 is provided on the outside of the rotating shaft 7. The connecting cylinder 13 and the rotating shaft 7 are movably installed together. The inner top surface of the connecting cylinder 13 is fixedly installed with a first electromagnet 14, and the top surface of the rotating shaft 7 is fixedly installed with a second electromagnet 15. A spring 16 is provided on the outside of the rotating shaft 7. When in use, the first electromagnet 14 and the second electromagnet 15 are turned on. The two electromagnets have the same name. When energized, the magnetic force generated repels each other, causing the second electromagnet 15 to drive the rotating shaft 7 to move downward, squeezing the spring 16 while moving. When the first electromagnet 14 and the second electromagnet 15 are closed, the compressed force of the spring 16 is released to drive the rotating shaft 7 to rise, so that the shear blade 9 can cut the seaweed raw materials at different positions inside the shearing tank 2;

[0036] By setting a telescopic component, the seaweed raw material enters the feed pipe 3 through the feed hopper 4, and then falls into the shearing tank 2 from the feed pipe 3. The material is prepared for the shearing work, and the first drive motor 11 is started. The shearing blade 9 on the rotating shaft 7 rotates together with the rotating shaft 7 to shear the seaweed raw material falling into the shearing tank 2, and the larger particles of seaweed are sheared into smaller particles or fragments. By controlling the power supply of the first electromagnet 14 and the second electromagnet 15, the magnetic force between the two can be changed. When the magnetic force changes, a downward force is generated on the rotating shaft 7, and the spring 16 is squeezed while moving. After the power supply of the electromagnet is turned off, the spring 16 releases the compressed potential energy, pushing the rotating shaft 7 to reset upward, and the shearing blade 9 is lifted accordingly, which can shear the upper layer of raw materials in the shearing tank 2. By repeatedly controlling the on and off of the electromagnet, the shearing blade 9 is reciprocating in the vertical direction to cover raw materials at different heights. The shearing blade 9 can move up and down in the shearing tank 2, and can dynamically cut seaweed raw materials at different positions without stopping, avoiding insufficient shearing of local raw materials and improving shearing uniformity.

[0037] As a further solution of the present invention, the shear blades 9 are in the form of a matrix of two layers of staggered blades;

[0038] By providing the shear blades 9, the lower two layers of staggered blade matrices can promptly shear the seaweed wrapped around the rotating shaft 7, effectively preventing a large amount of seaweed from being entangled and causing the rotating shaft 7 to be obstructed or even stopped, thereby reducing the probability of equipment failure, ensuring the continuity of the preparation process of the water-soluble fertilizer containing seaweed, and reducing the downtime maintenance costs and production delay losses caused by equipment failure.

[0039] As a further solution of the present invention, the shaft of the first drive motor 11 and the external fixed sleeve of the rotating column 12 are provided with a pulley 17, and a belt 18 is provided on the outside of the pulley 17;

[0040] By setting the belt 18, when starting, the first drive motor 11 starts to run, and its output shaft drives the fixed pulley 17 to rotate. The friction between the pulley 17 and the belt 18 causes the belt 18 to move, thereby driving the pulley 17 outside the rotating column 12 to rotate, and finally realizing the rotation of the rotating column 12. The belt transmission is elastic and can buffer the vibration and impact generated when the first drive motor 11 is running, so that the rotation of the rotating column 12 and the rotating shaft 7 is more stable.

[0041] As a further solution of the present invention, a discharge pipe 19 is provided on the bottom surface of the shear tank 2, a separation frame 20 is fixedly installed inside the base 1, a filter screen 21 is provided inside the separation frame 20, and a discharge port 22 is opened on one side of the base 1;

[0042] By setting the filter screen 21, when the seaweed raw material is fully sheared by the upper and lower layers of staggered blade matrices in the shearing tank 2, the sheared seaweed fragments fall from the discharge pipe 19 on the bottom of the shearing tank 2 due to gravity. The discharge pipe 19 guides the seaweed fragments to the separation rack 20 inside the base 1. The filter screen 21 in the separation rack 20 screens and separates the seaweed fragments. The fine seaweed particles that meet the particle size requirements pass through the filter screen 21 and are discharged through the discharge port 22 on one side of the base 1. As qualified shear products, they enter the subsequent water-soluble fertilizer preparation process; while the seaweed fragments with larger particle size that do not pass through the filter screen 21 are intercepted and slide to the other side. The seaweed fragments are screened by the filter screen 21, and the particle size of the discharged material can be accurately controlled to avoid affecting the dissolution effect and nutrient release of the subsequent water-soluble fertilizer due to uneven particle size of the fragments, thereby improving the quality and consistency of the final product.

[0043] As a further solution of the present invention, a return hole 23 is opened on one side of the base 1, and a return pipe 24 is fixedly sleeved inside the return hole 23. A spiral conveying shaft 25 is provided inside the return pipe 24. A second drive motor 27 is fixedly installed on the top surface of the return pipe 24. The shaft of the second drive motor 27 is fixedly connected to the spiral conveying shaft 25. An inclined tube 26 is provided on the outer circular wall of the return pipe 24, and the inclined tube 26 is connected to the shear tank 2;

[0044] By setting the return pipe 24, when the filter screen 21 in the separation frame 20 intercepts the seaweed fragments with larger particle size and slides to the other side, at this time, the second drive motor 27 is started, and its shaft drives the spiral conveying shaft 25 to rotate in the return pipe 24. The spiral conveying shaft 25 conveys the seaweed fragments accumulated at the return hole 23 upward along the return pipe 24 through the rotation of the spiral blades. As the fragments are lifted to the position of the inclined pipe 26, under the combined action of the spiral thrust and gravity, the fragments re-enter the shearing tank 2 through the inclined pipe 26. The seaweed fragments returning to the shearing tank 2 will be sheared again by the upper and lower layers of staggered blade matrices until their particle size meets the requirements. After being screened by the discharge pipe 19 and the filter screen 21, they are discharged from the discharge port 22. By continuously returning the large-size fragments for shearing, the particle size of the finally discharged seaweed fragments is ensured to be uniform, avoiding the influence of the dissolution rate and nutrient release efficiency of the water-soluble fertilizer due to insufficient shearing of some materials, thereby stabilizing and improving the product quality of the seaweed water-soluble fertilizer.

[0045] As a further solution of the present invention, a guide block 28 is fixedly installed on the bottom surface of the base 1;

[0046] By setting the guide block 28, since the guide block 28 fixedly installed on the bottom surface of the base 1 is in the shape of an inclined block, under the action of gravity, the accumulated seaweed fragments will slide down along the inclined surface of the guide block 28, automatically move toward the return hole 23, and finally enter the return hole 23, thereby reducing the risk of accumulation and blockage of the fragments in the base 1, allowing the material to enter the return system more smoothly and efficiently, thereby speeding up the entire circulation processing process.

[0047] As a further solution of the present invention, a solenoid valve 29 is provided on the outside of the discharge pipe 19;

[0048] By providing the solenoid valve 29 , the solenoid valve 29 can be quickly opened or closed by an electrical signal, thereby realizing control over the output of the seaweed fragments in the discharge pipe 19 .

[0049] As a further solution of the present invention, an observation window 30 is provided on the outside of the shear tank 2;

[0050] By providing the observation window 30 , the operator does not need to open the shearing tank 2 , and can visually view the shearing progress of the seaweed raw material, the operation status of the blades, and the distribution status of the material in the tank through the observation window 30 .

[0051] Working principle: Please refer to Figures 1-6 As shown, seaweed material enters the feed pipe 3 through the feed hopper 4 and falls into the shearing tank 2. The first drive motor 11 drives the rotating column 12 and the rotating shaft 7 via the pulley 17 and belt 18, causing the upper and lower layers of the staggered blade matrix of shear blades 9 to shear the material. During the shearing process, the telescopic assembly uses the repulsive force between the like poles of the first and second electromagnets 14 and 15 to push the rotating shaft 7 downward and compress the spring 16. After the power is turned off, the spring resets, driving the rotating shaft 7 upward, achieving vertical reciprocating motion of the shear blades 9, covering material at different heights and improving shearing uniformity. The sheared material is then controlled by the solenoid valve 29 of the discharge pipe 19 and is screened by the filter 21 of the separation rack 20 in the base 1. The qualified particle size is discharged from the discharge port 22, while the unqualified large particle size is guided by the guide block 28 and slides down the return hole 23. The second drive motor 27 drives the screw conveyor shaft 25 through the return pipe 24 and the inclined pipe 26 to return to the shearing tank 2 for re-shearing. In addition, the observation window 30 can monitor the shearing status in real time, the elastic buffer of the belt drive ensures smooth operation, and the staggered blade matrix prevents seaweed from entangled with the shaft, ensuring continuous operation of the equipment.

[0052] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
