Description

Technical Field

[0001] The invention belongs to the technical field of fertilizer preparation, and in particular relates to fertilizer making equipment and a fertilizer making method for a sandy soil nutrient synergistic fertilizer. Background Art

[0002] Sandy soil, also known as sandy soil or sandy soil, refers to soil that contains more sand particles and has a certain degree of viscosity. It is mainly composed of particles of 0.075 to 2 mm. There is no cohesion between the particles. It is loose in nature, has no plasticity, and is extremely permeable.

[0003] Sandy soil has the disadvantages of poor water and fertilizer retention capacity and low nutrient content. These disadvantages will make crops vulnerable to drought and nutrient deficiency during growth, slow growth, and prolonged growth cycle, which in turn affects crop yield and quality. In order to overcome these shortcomings and improve the production capacity of the land and the yield and quality of crops, improvement measures need to be taken. Common improvement measures are to add fertilizers to sandy soil to improve soil structure, increase soil water and fertilizer retention capacity, and provide sufficient nutrients for crops.

[0004] Patent CN115253854A discloses a processing device for a fluid fertilizer enhancer, which can grind granular materials preliminarily and enter the tank body, thereby improving the mixing effect of the device. However, the distance between the grinding plate and the discharge plate remains unchanged. When grinding the granular materials, only the outermost granular materials can be ground in sequence, the grinding efficiency is low, and the material particles cannot be fully ground.

[0005] In the current prior art, when the sludge is stirred and mixed with the bacterial agent, a stirring rod is usually used to perform unidirectional rotation stirring on the sludge. Although the sludge and the bacterial agent can be mixed in this way, due to the strong viscosity of the sludge, the unidirectional rotation stirring cannot fully break up the sludge, so that agglomeration and caking will occur during the mixing process of the sludge and the bacterial agent.

[0020] Beneficial effects of the present invention: The present invention starts the motor to rotate the second sprocket, and with the cooperation of the chain, the first sprocket and the second sprocket rotate synchronously. The rotation of the second sprocket, with the cooperation of the vertical rod and the limit rod, causes the reciprocating screw to reciprocate and rise and fall. The reciprocating screw, through the cooperation of the first connecting rod and the supporting ring, causes the blanking plate to rise and fall synchronously. With the cooperation of the first sleeve and the second sleeve, the blanking plate can rotate while being lifted and lowered. Therefore, when the blanking plate rises to a position close to the grinding plate, the bacterial agent can be fully ground into powder, thereby improving the grinding efficiency.

[0021] When the first sleeve of the present invention rotates, the baffle plate will rotate synchronously, and the rotation of the baffle plate drives the discharge port to rotate. When the discharge port corresponds to the lower side of the feed hopper, part of the bacterial agent in the discharge hopper will fall onto the discharge plate. The rotation of the discharge plate generates centrifugal force. Under the action of the centrifugal force, the bacterial agent is evenly scattered to different positions of the discharge plate. When the discharge port rotates to a position away from the feed hopper, the baffle plate blocks the lower side of the discharge hopper, and the bacterial agent in the discharge hopper cannot fall, thereby achieving the purpose of timed discharge. It is only necessary to add the bacterial agent to the feed hopper, thereby reducing the number of operating steps.

[0022] The second sprocket of the present invention will drive the second connecting rod to rotate synchronously during the rotation process, and the third connecting rod will be driven to rotate synchronously under the cooperation of the first bevel gear and the second bevel gear. The rotation of the third connecting rod drives the push rod to rotate. During the rotation of the push rod, the push rod will contact the lifting block and push the lifting block to make the connecting block and the collar rotate around the third connecting rod. During the rotation process, the connecting block will drive the connecting arm and the lifting rod to rise. The rising of the lifting rod drives the extrusion block to rise. The rising of the extrusion block will squeeze the spring. The spring will contract and store the restoring force when it is squeezed. After the rod rotates 270°, the lifting block is on the right side of the push rod, and the lifting rod is no longer blocked by the push rod. Under the action of the spring restoring force, the lifting rod will quickly reset. At this time, if the unloading plate is in an upward state, the unloading plate will rise to three-quarters of the height of the reciprocating screw rod, and the unloading plate will just correspond to the knocking block. The knocking block will knock on the unloading plate, thereby knocking down the powdered inoculant adhering to the unloading plate and knocking apart the stacked inoculant, which can prevent the powdered inoculant adhering to the unloading plate from affecting the normal grinding of the inoculant, avoid waste of the inoculant, and improve grinding efficiency.

[0023] The blanking plate of the present invention will drive the third sleeve and the fourth sleeve to rotate synchronously during the rotation process. The rotation of the fourth sleeve will drive the first stirring rod to rotate, and at the same time drive the third bevel gear to rotate. The third bevel gear cooperates with the fourth bevel gear and the fifth bevel gear, and under the limiting conditions of the sliding rod and the sliding rail, the fifth bevel gear drives the fourth connecting rod to rotate in the opposite direction of the first stirring rod, so that the supporting rod, the scraper and the second stirring rod rotate in the opposite direction of the first stirring rod. The first stirring rod and the second stirring rod rotate in opposite directions to each other, which can generate a strong shear force, can fully break up the sludge, and can be fully mixed with the bacterial agent, can reduce agglomeration and caking, and improve the quality.

[0027] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0028] See also Figure 1 - Fig. 9 As shown, a fertilizer making device and a fertilizer making method for sandy soil nutrient enhanced fertilizer include a preparation tank 1 for preparing fertilizer.

[0029] A feed hopper 11 is connected to the upper surface of the preparation tank 1 , and the bacterial agent can be added into the preparation tank 1 through the feed hopper 11 .

[0030] A feeding pipe 12 is obliquely connected above the preparation tank 1 for adding sludge into the preparation tank 1 .

[0031] It is worth noting here that the following benefits can be obtained by combining silt with sandy soil: 1. The organic cementing substances in the silt can combine with the sand particles in the sandy soil to form more aggregates, which can improve the particle structure of the sandy soil and make the sandy soil more stable; Second, the soluble minerals and organic cementing substances in the silt can enhance the bonding force between aggregates, thereby improving the stability of aggregates and helping to reduce the risk of soil erosion and water loss; 3. Silt is rich in organic matter and various nutrients, which can provide nutrients for sandy soil and improve the fertility of sandy soil. At the same time, the addition of silt can also improve the soil's water and fertilizer retention capacity, which is helpful for the growth and development of crops.

[0032] A discharge pipe 13 is connected below the preparation tank 1 to discharge the prepared fertilizer.

[0033] A valve 14 is connected to the middle of the discharge pipe 13 to control the opening and closing of the discharge pipe 13 .

[0034] A first sprocket 2 is arranged in the middle part above the preparation tank 1, and a second sprocket 21 is arranged at a position above the preparation tank 1 corresponding to the first sprocket 2. A chain 22 is meshed between the first sprocket 2 and the second sprocket 21. Through the cooperation of the chain 22, the first sprocket 2 and the second sprocket 21 can rotate synchronously.

[0035] A motor 211 is connected to the middle of the upper surface of the second sprocket 21 , and the motor 211 is used to drive the second sprocket 21 to rotate.

[0036] A mounting bracket 212 is connected to the position of the upper surface of the preparation tank 1 corresponding to the motor 211 , and is used to install and fix the motor 211 .

[0037] A mounting plate 213 is connected to the mounting frame 212 at a position corresponding to the first sprocket 2 . The first sprocket 2 is connected to the mounting plate 213 via a bearing. The mounting plate 213 is used to fix the position of the first sprocket 2 .

[0038] The circumference of the second sprocket 21 is four times that of the first sprocket 2. With this arrangement, one rotation of the second sprocket 21 will cause the first sprocket 2 to rotate four times, which can grind the bacterial agent when the unloading plate 25 is reciprocatingly lifted and lowered, can knock the unloading plate 25 with the knocking block 552, and can fully stir the sludge by reciprocating the lifting and lowering of the first stirring rod 611 and the second stirring rod 664, so that the sludge and the ground bacterial agent are fully mixed.

[0039] A reciprocating screw rod 23 is threadedly connected to the middle portion of the first sprocket 2 to drive the blanking plate 25 to move up and down.

[0040] The number of thread turns of the reciprocating screw 23 is four. Through this setting, the reciprocating screw 23 can be lifted and lowered once after the second sprocket 21 rotates two turns or the first sprocket 2 rotates eight turns, which is convenient for controlling the knocking frequency of the knocking block 552 on the blanking plate 25 and for controlling the lifting and lowering frequency of the first stirring rod 611 and the second stirring rod 664.

[0041] The lower end of the reciprocating screw rod 23 is connected to a first connecting rod 231, and the first connecting rod 231 is located in the preparation tank 1. The lower end of the first connecting rod 231 is connected to a support ring 232, and the outer side of the support ring 232 is rotatably connected to a discharge plate 25. The support ring 232 is used to support the discharge plate 25 and fix the position of the discharge plate 25. The discharge plate 25 is used to drop the ground bacterial agent.

[0042] The spacing between the blanking plate 25 and the preparation tank 1 is 0.1 mm-0.3 mm. This arrangement can prevent the bacterial agent from falling from the gap between the blanking plate 25 and the preparation tank 1 to the bottom of the preparation tank 1.

[0043] The blanking plate 25 is in a trapezoidal shape. This arrangement facilitates the distribution of the bacterial agent and prevents the accumulation of the bacterial agent.

[0044] A vertical rod 24 is arranged at a position corresponding to the reciprocating screw 23 in the middle of the preparation tank 1, and the lower end of the vertical rod 24 is connected to the lower part of the inside of the preparation tank 1, and a limiting rod 241 is connected to the position corresponding to the reciprocating screw 23 above the vertical rod 24. The reciprocating screw 23, the first connecting rod 231 and the support ring 232 are provided with a limiting groove 242 corresponding to the position of the limiting rod 241, and the limiting rod 241 is slidably connected in the limiting groove 242. Through the cooperation of the vertical rod 24, the limiting rod 241 and the limiting groove 242, the reciprocating screw 23 can be reciprocated and lifted normally, preventing the first sprocket 2 from only driving the reciprocating screw 23 to rotate, causing the reciprocating screw 23 to be unable to reciprocate and lift.

[0045] The first sprocket 2 is connected to a first sleeve 3 on the lower surface, the first sleeve 3 is located outside the reciprocating screw rod 23, the lower end of the first sleeve 3 is rotatably connected to the top of the preparation tank 1, the upper surface of the blanking plate 25 is connected to a second sleeve 31, the second sleeve 31 is located between the first sleeve 3 and the first connecting rod 231, the second sleeve 31 is slidably connected in the first sleeve 3, a plurality of evenly arranged positioning rods 32 are connected to the outside of the second sleeve 31, a plurality of evenly arranged positioning grooves 33 are provided in the first sleeve 3 corresponding to the positions of the positioning rods 32, the positioning rods 32 are slidably connected in the positioning grooves 33, through this arrangement, the second sleeve 31 can only slide in the first sleeve 3, and the second sleeve 31 cannot rotate in the first sleeve 3, so that when the first sprocket 2 rotates, the blanking plate 25 can be rotated under the cooperation of the first sleeve 3 and the second sleeve 31, and at the same time, the second sleeve 31 can slide in the first sleeve 3 under the cooperation of the reciprocating screw rod 23, and the reciprocating lifting of the blanking plate 25 is realized.

[0046] A grinding plate 26 is disposed above the interior of the preparation tank 1 . The grinding plate 26 has the same shape as the blanking plate 25 . The grinding plate 26 cooperates with the blanking plate 25 to grind the bacterial agent.

[0047] The distance between the blanking plate 25 and the grinding plate 26 is equal to the length of the reciprocating screw rod 23. Through this arrangement, the lifting plate and the grinding plate 26 can accurately grind the bacterial agent.

[0048] During specific use, the second sprocket 21 is rotated by starting the motor 211, and with the cooperation of the chain 22, the first sprocket 2 and the second sprocket 21 rotate synchronously. The rotation of the second sprocket 21, with the cooperation of the vertical rod 24 and the limit rod 241, causes the reciprocating screw rod 23 to reciprocate and rise and fall. The reciprocating screw rod 23 makes the blanking plate 25 rise and fall synchronously through the cooperation of the first connecting rod 231 and the support ring 232. The blanking plate 25 can be rotated while being lifted and lowered with the cooperation of the first sleeve 3 and the second sleeve 31. Therefore, when the blanking plate 25 rises to a position close to the grinding plate 26, the bacterial agent can be fully ground into powder, thereby improving the grinding efficiency.

[0049] A baffle plate 4 is connected to the outer side of the lower end of the first sleeve 3 , and a discharge port 41 is formed on the baffle plate 4 at a position corresponding to the lower end of the feed hopper 11 .

[0050] During specific use: when the first sleeve 3 rotates, the baffle 4 will rotate synchronously, and the rotation of the baffle 4 drives the discharge port 41 to rotate. When the discharge port 41 corresponds to the lower part of the feed hopper 11, part of the bacterial agent in the discharge hopper will fall onto the discharge plate 25. The rotation of the discharge plate 25 generates centrifugal force. Under the action of the centrifugal force, the bacterial agent is evenly scattered to different positions of the discharge plate 25. When the discharge port 41 rotates to a position away from the feed hopper 11, the baffle 4 blocks the lower part of the discharge hopper, and the bacterial agent in the discharge hopper cannot fall, thereby achieving the purpose of timed discharge. It is only necessary to add the bacterial agent to the feed hopper 11, which reduces the number of operating steps.

[0051] A second connecting rod 5 is connected to the middle part of the lower surface of the second sprocket 21 . By connecting the second connecting rod 5 , the lifting rod 551 can be lifted.

[0052] The lower end of the second connecting rod 5 is connected to the first bevel gear 501, and the second bevel gear 502 is meshed below the first bevel gear 501. The side of the second bevel gear 502 away from the second connecting rod 5 is connected to the third connecting rod 503. By connecting the third connecting rod 503, the knocking block 552 can be close to the middle of the blanking plate 25.

[0053] A fixing plate 504 is connected to the upper surface of the preparation tank 1 at the position of the third connecting rod 503 , so as to support the third connecting rod 503 and fix the position of the third connecting rod 503 .

[0054] One end of the third connecting rod 503 away from the second bevel gear 502 is connected to a push rod 51 for pushing the lifting block 54 .

[0055] The third connecting rod 503 is rotatably connected to a collar 52 on the outside, a connecting block 53 is connected below the collar 52, a lifting block 54 is connected to the side of the connecting block 53 away from the third connecting rod 503, and the push rod 51 cooperates with the lifting block 54 to lift the lifting rod 551.

[0056] The connecting block 53 is rotatably connected to a connecting arm 55 at one side away from the third connecting rod 503 . The lower end of the connecting arm 55 is rotatably connected to a lifting rod 551 . The lower end of the lifting rod 551 is connected to a knocking block 552 for knocking the blanking plate 25 .

[0057] The preparation tank 1 is connected to a shell 553 at a position corresponding to the lifting rod 551 , and an extrusion block 554 is connected to the outside of the lifting rod 551 corresponding to the inside of the shell 553 . The extrusion block 554 is slidably connected in the shell 553 for extruding the spring 555 .

[0058] A spring 555 is connected between the extrusion block 554 and the housing 553 . The spring 555 is located outside the lifting rod 551 . The spring 555 is used to reset the lifting rod 551 .

[0059] The extension amount of the lifting rod 551 below the corresponding shell 553 is equal to one-quarter of the length of the reciprocating screw 23. Through this setting, it can be ensured that the knocking block 552 knocks on the blanking plate 25.

[0060] During specific use, the second sprocket 21 will drive the second connecting rod 5 to rotate synchronously during the rotation process, and with the cooperation of the first bevel gear 501 and the second bevel gear 502, the third connecting rod 503 will be driven to rotate synchronously. The rotation of the third connecting rod 503 drives the push rod 51 to rotate. During the rotation of the push rod 51, the push rod 51 will contact the lifting block 54 and push the lifting block 54 to make the connecting block 53 and the collar 52 rotate around the third connecting rod 503. During the rotation process, the connecting block 53 will drive the connecting arm 55 and the lifting rod 551 to rise. The rising of the lifting rod 551 drives the extrusion block 554 to rise. The rising of the extrusion block 554 will squeeze the spring 555, and the spring 555 will be squeezed and contracted. The lifting block 551 is located on the right side of the push rod 51 after the push rod 51 rotates 270°. The lifting rod 551 is no longer blocked by the push rod 51. Under the action of the restoring force of the spring 555, the lifting rod 551 will be quickly reset. At this time, if the blanking plate 25 is in an ascending state, the blanking plate 25 will rise to three-quarters of the height of the reciprocating screw 23. The blanking plate 25 will just correspond to the knocking block 552. The knocking block 552 will knock on the blanking plate 25, so that the powdered bacterial agent adhering to the blanking plate 25 can be knocked off and the stacked bacterial agent can be knocked loose, so as to avoid the powdered bacterial agent adhering to the blanking plate 25 affecting the normal grinding of the bacterial agent, avoid the waste of the bacterial agent, and improve the grinding efficiency.

[0061] A third sleeve 6 is connected to the middle of the lower surface of the blanking plate 25 . The third sleeve 6 can be arranged to keep the fourth sleeve 61 away from the first connecting rod 231 , thereby preventing the fourth sleeve 61 and the first connecting rod 231 from influencing each other.

[0062] A fourth sleeve 61 is connected below the third sleeve 6. The fourth sleeve 61 is slidably connected to the outside of the vertical rod 24. A plurality of groups of evenly arranged first stirring rods 611 are connected to the outside below the fourth sleeve 61. The first stirring rods 611 are used to stir the sludge so that the sludge and the bacterial agent can be fully mixed.

[0063] The third bevel gear 62 is connected to the outer side of the upper part of the fourth sleeve 61, the fourth bevel gear 64 is meshed below the third bevel gear 62, and the fifth bevel gear 65 is meshed below the fourth bevel gear 64. The position of the upper outer side of the fourth sleeve 61 corresponding to the fourth bevel gear 64 and the fifth bevel gear 65 is connected to a U-shaped plate 63 through a bearing. The fourth bevel gear 64 is connected to the middle part of the U-shaped plate 63 through a bearing, and the fifth bevel gear 65 is connected to the bottom of the U-shaped plate 63 through a bearing. A sliding rod 621 is connected to the side of the U-shaped plate 63 away from the fourth bevel gear 64, and a sliding rail 622 is provided at the position of the preparation tank 1 corresponding to the sliding rod 621. The sliding rod 621 is slidably connected in the sliding rail 622, and the sliding rod 621 cooperates with the sliding rail 622 so that the U-shaped plate 63 can only rise but cannot rotate.

[0064] A fourth connecting rod 66 is connected below the fifth bevel gear 65, and a through hole 661 is provided at a position corresponding to the fourth sleeve 61 in the middle of the fifth bevel gear 65 and the fourth connecting rod 66. The fifth bevel gear 65 and the fourth connecting rod 66 are rotatably connected to the outside of the fourth sleeve 61, and a plurality of evenly arranged support rods 662 are connected to the outside below the fourth connecting rod 66. A scraper 663 is connected to one end of the support rod 662 away from the fourth connecting rod 66 for scraping off the sludge adhering to the inner wall of the preparation tank 1.

[0065] The scraper 663 is connected to a plurality of evenly arranged second stirring rods 664 at the position corresponding to the first stirring rod 611. The first stirring rod 611 and the second stirring rod 664 are arranged alternately. Through the cooperation of the first stirring rod 611 and the second stirring rod 664, the sludge and the bacterial agent can be fully and quickly mixed.

[0066] During specific use, the blanking plate 25 will drive the third sleeve 6 and the fourth sleeve 61 to rotate synchronously during the rotation process. The rotation of the fourth sleeve 61 drives the first stirring rod 611 to rotate, and at the same time drives the third bevel gear 62 to rotate. The third bevel gear 62 cooperates with the fourth bevel gear 64 and the fifth bevel gear 65, and under the limiting conditions of the slide bar 621 and the slide rail 622, the fifth bevel gear 65 drives the fourth connecting rod 66 to rotate in the opposite direction of the first stirring rod 611, so that the support rod 662, the scraper 663 and the second stirring rod 664 rotate in the opposite direction of the first stirring rod 611. The first stirring rod 611 and the second stirring rod 664 rotate in opposite directions to each other, which can generate a strong shear force, can fully break up the sludge, and can be fully mixed with the bacterial agent, can reduce agglomeration and caking, and improve the quality.

[0067] The fertilizer making method comprises the following steps: S1: adding sludge into the preparation tank 1 through the feed pipe 12; S2: Add the bacterial agent into the feed hopper 11; S3: Start the motor 211 to make the second sprocket 21 drive the first sprocket 2 to rotate; S4: The bacterial agent falls onto the top of the discharge plate 25 through the discharge port 41; S5: the blanking plate 25 cooperates with the grinding plate 26 to grind the bacterial agent into powder, and the powdered bacterial agent falls below the preparation tank 1 through the blanking hole of the blanking plate 25; S6: The knocking block 552 knocks the blanking plate 25 to knock off the powdered bacterial agent adhering to the blanking plate 25 and to knock the stacked bacterial agents apart; S7: The sludge and the bacterial agent are uniformly and fully mixed by the first stirring rod 611 and the second stirring rod 664 rotating alternately and moving up and down reciprocatingly; S8: After the fertilizer is prepared, the valve 14 is opened to collect the fertilizer.
