Description

Technical Field

[0001] The invention relates to the technical field of slow-release fertilizer production, in particular to multi-row bag-controlled slow-release fertilizer production equipment. Background Art

[0002] Slow-release fertilizer, also known as controlled-release fertilizer or long-acting fertilizer, uses physical, chemical or biological methods to encapsulate nutrients in special materials to form slightly soluble compounds or particles to achieve a slow-release effect. It is a fertilizer that uses specific production processes and technologies to slowly release nutrients in the soil. Its core concept is to control the release rate and time of nutrients to meet the nutrient needs of crops at different growth stages and maximize the use of fertilizers. The production of slow-release fertilizers requires the use of cleaning equipment, crushing equipment, mixing equipment, fermentation equipment, bagging equipment, etc. These equipment used for slow-release fertilizer production are collectively referred to as slow-release fertilizer production equipment.

[0003] The bag-controlled fertilizer slow-release technology is a new type of fertilization technology developed based on the theory of plant steady-state nutrition. The biggest difference between it and ordinary controlled fertilization is that ordinary controlled fertilization is to wrap the fertilizer particles with biodegradable film to achieve the controlled fertilization effect, while bag-controlled slow fertilization is to control the release of fertilizer nutrients through the fertilizer outer packaging bag made of special materials. The nutrient release channel of the fertilizer packaging bag can be adjusted arbitrarily according to needs through physical means, so that the nutrient dissolution rate is consistent with the actual needs of the crop.

[0004] The principle of bag-controlled fertilizer slow-release technology is to mix nitrogen, phosphorus, potassium and various trace elements required by crops according to the proportions required by different crops, and then package them in microporous bags (or degradable minerals are added to the bag materials). The fertilizer releases nutrients through the micropores on the bag. The micropores on the bag can automatically expand and shrink according to the soil temperature and the amount of water, so as to control the nutrient release rate. When the temperature is low and there is less rain in winter and early spring, the micropores on the bag will shrink very small and almost no nutrients will be released. At this time, the root activity of crops is less and the nutrients required are also less; after the beginning of spring, with the increase of temperature and rain, the micropores will continue to expand, and the nutrient release rate will gradually accelerate. At this time, the root activity of crops will also continue to accelerate, and the nutrients required will also increase. This kind of fertilizer will continuously and steadily release nutrients throughout the growth process of crops, and the supply of nutrients is well synchronized with the needs of crops, neither too much nor too little. If it rains or waters, only a small part of the fertilizer released at that time will be lost with the water, and the rest of the fertilizer will remain in the bag and will not be lost. It is almost unaffected by the soil type, which creates conditions for achieving quantitative fertilization or precise fertilization in the true sense. Moreover, the packaging bag of bag-controlled slow-release fertilizer is mainly composed of degradable wood pulp paper, which is easy to decompose when buried in the soil, does not pollute the soil and air, and plays a role in loosening the soil.

[0005] The slow-release technology of bag-controlled fertilizer has been tested and demonstrated on a large scale and promoted in agriculture and forestry across the country, which has confirmed that the slow-release technology of bag-controlled fertilizer has significant effects in energy saving, environmental protection, increased production and income.

[0006] Although the technology of slow-release bag-controlled fertilizer has been developed, the corresponding production equipment of bag-controlled slow-release fertilizer has not been further developed and still remains on the basis of manual bagging. When bag-controlled slow-release fertilizer is produced and packaged, the manual filling speed is slow, the labor intensity is high, the mechanization degree is not high, the work efficiency is low, and the slow-release fertilizer is in direct contact with the air and is easy to absorb moisture in the air and get damp.

The auxiliary lifting platform 6 is used to transport the sealed filling material tank 5 storing the product to be packaged from the ground to the top of the bagging machine 2, or to transport the used sealed filling material tank 5 from the top of the bagging machine 2 to the ground. The auxiliary lifting platform 6 is used to assist the staff to replace the sealed filling material tank 5, and the staff does not need to repeatedly go up and down the platform 1 manually, thereby reducing the labor intensity of the staff.

[0044] like Figures 5 to 8 As shown, a feed hole 406 is provided at the connection between the sealing cover plate 402 and the feed pipe 403, five feed hoppers are provided at the bottom end of the storage box 401, and a sealing material hole 405 is provided at the bottom end of each feed hopper, and a sealing material tube 404 is provided below the sealing material hole 405, and the sealing material tube 404 passes through the top of the bagging machine 2 and is connected to the bottom end of the feed funnel, and a feed channel is provided inside the sealing material tube 404, and a solenoid valve is provided at the bottom end of the feed channel, and the bottom end of the sealing material tube 404 extends to the folding forming of the packaging bag. The module 9 is inside and wrapped by the folded packaging bag, and the top of the feed channel is fitted with the bottom of the packaging material hole 405, and the product to be packaged is filled into the storage box 401. The packaging material tube 404 of the packaging feed structure 4 is aligned with the folded part of the strip packaging paper 11, that is, the upper opening of the cylindrical packaging bag 12, and then the product to be packaged is directly sent into the folded cylindrical packaging bag 12 through the five feeding funnels and the packaging material tube 404 at the bottom of the storage box 401, so as to achieve five bags of products being packaged at one time, thereby improving the packaging efficiency.

[0045] Five protective shells 407 are provided inside the material storage box 401. The five protective shells 407 are aligned one by one with the five packaging material holes 405 and their axes coincide with each other. Fixing strips 408 are fixed between two adjacent protective shells 407 and between the protective shells 407 and the inner wall of the material storage box 401. The top of the protective shell 407 is a conical surface. A double-headed motor 409 is installed inside the protective shell 407. The fixing strips 408 are used to support and reinforce the protective shell 407 to ensure that the protective shell 407 will not fall and cause the packaging material hole 405 to be blocked by the fallen protective shell 407.

[0046] The upper output shaft of the dredging double-headed motor 409 is fixed with a feed rotating shaft 411, the top of the feed rotating shaft 411 passes through the top of the protective shell 407 and extends to the inside of the feed pipe 403, and the lower output shaft of the dredging double-headed motor 409 is fixed with a feed rotating rod 410, the bottom end of the feed rotating rod 410 is fixed with a disc, and a plurality of anti-blocking strips 412 are fixed on the upper surface of the disc, and the anti-blocking strips 412 are distributed in a circular array around the axis of the feed rotating rod 410, and the anti-blocking strips 412 are spiral The anti-clogging strip 412 is a long strip, and the bottom end of the anti-clogging strip 412 is closer to the feeding rotating rod 410 than the top end. The feeding rotating rod 410 is driven to rotate by the double-headed motor 409, so that the feeding rotating rod 410 drives the anti-clogging strip 412 to rotate around the axis of the feeding rotating rod 410, so that the products to be packaged filled in the storage box 401 can flow, avoiding the accumulation of the products to be packaged in the storage box 401 and causing the feeding funnel to be blocked, thereby ensuring that the packaging and feeding of the products to be packaged will not be affected.

[0047] like Figure 5 , Figure 6 , Figures 9 to 12 As shown, the sealed filling tank 5 includes a filling tank body 501, a docking ring groove 511 is provided at the bottom of the filling tank body 501, and the filling tank body 501 is docked with the top of the feed pipe 403 through the docking ring groove 511. A filling port 504 is provided at the center of the bottom end of the filling tank body 501, and a sealing plug 502 is detachably installed on the top of the filling tank body 501. Four symmetrically distributed support columns 503 are fixed to the bottom surface of the filling tank body 501, and the height of the support columns 503 is consistent with the height of the feed pipe 403. The filling tank body 501 is used to seal and store the products packaged after production to prevent the products to be packaged from coming into contact with dust in the air and getting damp during storage or filling into the storage box 401.

[0048] A rotary docking block 413 is fixed to the top of the feed rotary shaft 411, a rotary guide rod 507 is fixed to the bottom of the sealing block 505, a rotary docking groove 510 is provided at the bottom of the rotary guide rod 507, the rotary guide rod 507 is docked with the feed rotary shaft 411 through the rotary docking groove 510 and the rotary docking block 413, the top of the sealing block 505 is a cone, and a plurality of auxiliary feed strips 506 are fixed to the outer surface of the cone, the auxiliary feed strips 506 are distributed in a circular array around the axis of the sealing block 505, the auxiliary feed strips 506 are in a spiral state around the axis of the sealing block 505, and the bottom end of the auxiliary feed strip 506 is close to the axis of the sealing block 505, and the top end of the auxiliary feed strip 506 is close to the filling The inner wall of the material tank body 501 ensures that after the filling material tank body 501 is docked with the feed pipe 403, the double-headed motor 409 is unblocked. When driving the feed rotating rod 410 and the feed rotating shaft 411 to rotate, the feed rotating shaft 411 can drive the sealing block 505 and the auxiliary feed strip 506 to rotate through the rotating docking block 413 and the rotating guide rod 507. The rotating auxiliary feed strip 506 is used to make the to-be-packaged product stored inside the filling material tank body 501 flow in a spiral in the filling material tank body 501, thereby accelerating the flow speed of the to-be-packaged product to the filling material port 504, increasing the speed at which the to-be-packaged product inside the filling material tank body 501 enters the material storage box 401, and increasing the loading speed during the packaging process.

[0049] A fixing block 509 is fixed on the inner side of the filling port 504, and a guide tube 508 is fixed on one end of the fixing block 509. The axis of the guide tube 508 coincides with the axis of the filling port 504. The rotating guide rod 507 is slidably inserted into the inner side of the guide tube 508. The maximum outer diameter of the sealing block 505 is consistent with the inner diameter of the filling port 504. The guide tube 508 and the fixing block 509 are used to support the position of the rotating guide rod 507 and the sealing block 505, and the axis of the sealing block 505 always coincides with the axis of the filling port 504, so that the sealing block 505 can smoothly block the filling port 504 after falling.

[0050] When the slow-release fertilizer production equipment is in use, firstly, the packaging bag raw material paper roll winding roller 801 is connected to the bagging machine 2 through the bracket and the supporting shaft, and the packaging bag base paper 10 passes through the surface of multiple transmission rollers 802, between two transmission rollers 803, and between the thin shaft 804 and the supporting roller in sequence. The four axially equidistant annular blades 805 of the thin shaft 804 cut the packaging bag base paper 10 into five strips of packaging paper 11 with equal widths. The gluing head of the gluing machine 903 is attached to one side of the strip packaging paper 11 to apply glue to the side of the strip packaging paper 11. The paper material guide plate mechanism on both sides of the strip packaging paper 11 works, and the stepping motor B902 drives the guide flap 901 to rotate. The guide flap 901 guides and folds the side of the strip packaging paper 11, and the strip packaging paper 11 is folded into a cylindrical packaging bag 12. The folded cylindrical packaging bag 12 is directly wrapped on the outside of the packaging material tube 404.

[0051] The staff for packaging and loading arrives at the top of the manual operation platform 1 through the manual operation platform 1, and the staff for carrying the sealed filling material tank 5 during packaging carries the sealed filling material tank 5 to the vicinity of the auxiliary lifting platform 6, and then transports the sealed filling material tank 5 on the ground to the top of the bagging machine 2 through the auxiliary lifting platform 6. At this time, the staff lifts the sealed filling material tank 5 and docks the sealed filling material tank 5 with the packaging feeding structure 4, and ensures that the docking ring groove 511 at the bottom of the filling material tank body 501 is aligned with the top of the feeding pipe 403 during docking. When the bottom end of the filling tank body 501 is butted with the top end of the feed pipe 403, the top end of the feed rotating shaft 411 enters the guide tube 508, and the feed rotating shaft 411 pushes the rotating guide rod 507 and the sealing block 505 upward. After the sealing block 505 is pushed upward, a gap appears between the sealing block 505 and the filling port 504, and the product to be packaged in the filling tank body 501 slides down along the gap, and the sliding product to be packaged enters the feed pipe 403 along the filling port 504 and finally enters the storage box 401;

[0052] After the five sealed filling material tanks 5 are connected to the five feeding pipes 403 one by one, the power of the bagging machine 2 and the unblocking double-headed motor 409 is turned on. After the unblocking double-headed motor 409 is started, the feeding rotating rod 410 and the feeding rotating shaft 411 are driven to rotate. The feeding rotating shaft 411 drives the rotating docking block 413 to rotate during rotation. When the rotating docking block 413 rotates to be flush with the rotating docking groove 510 at the bottom of the rotating guide rod 507, the sealing block 505 falls downward, and the rotating docking block 413 is clamped on the inner side of the rotating docking groove 510. As the feeding rotating shaft 411 continues to rotate, the rotating docking block 413 is rotated. The connecting block 413 drives the rotating guide rod 507, the sealing block 505 and the auxiliary feeding strip 506 to rotate simultaneously with the feeding rotating shaft 411, and the auxiliary feeding strip 506 drives the product to be packaged in the filling tank body 501 to flow in a spiral manner inside the filling tank body 501 when rotating, and the spirally flowing product to be packaged is accelerated to flow into the filling port 504, thereby increasing the speed at which the product to be packaged in the filling tank body 501 passes through the filling port 504 and the feeding pipe 403 to enter the storage box 401, thereby increasing the filling speed of the product to be packaged during packaging, thereby improving the work efficiency of the staff;

[0053] After the product to be packaged inside the filling material tank body 501 is completely filled into the material storage box 401, it is only necessary to replace the sealed filling material tank 5. After the product to be packaged enters the material storage box 401, the inside of the material storage box 401 is gradually filled up. After the unblocking double-headed motor 409 is started, it drives the feeding rotating rod 410 to rotate, so that the feeding rotating rod 410 drives the anti-blocking strip 412 to make a circular motion around the axis of the feeding rotating rod 410, so that the anti-blocking strip 412 causes the product to be packaged filled in the material storage box 401 to spirally flow into the feeding funnel at the bottom of the material storage box 401, and the spirally flowing product will not accumulate at the bottom of the material storage box 401, thereby avoiding the bottom of the material storage box 401 from being blocked;

[0054] Next, the solenoid valve at the bottom of the internal feeding channel of the packaging material tube 404 is started at a fixed time, and the five feeding funnels and five packaging material tubes 404 at the bottom of the storage box 401 directly extend into the folded cylindrical packaging bag 12, so as to synchronously and package five bags of products at a time, and the products to be packaged in the storage box 401 are transported to the inside of the cylindrical packaging bag 12 folded and formed by the packaging bag folding and forming module 9 at a fixed time and quantity. After the cylindrical packaging bag 12 is filled with a fixed quantity of products, the packaging bag heat sealing and cutting module 7 includes a transverse heat sealing strip and a cutting knife, and the transverse heat sealing strip and the cutting knife of the packaging bag heat sealing and cutting module 7 are used and driven to move laterally toward the cylindrical packaging bag 12. The packaging bag heat sealing and cutting module 7 is driven by a cylinder to heat seal and cut the packaging bag filled with the product. After completing the heat sealing and cutting of the packaged product, the packaging bag heat sealing and cutting module 7 is reset and retracted to release the squeezing of the cylindrical packaging bag 12, and the cylindrical packaging bag 12 continues to move downward for a fixed distance accompanied by driving components such as transmission rollers. After descending, the above-mentioned heat sealing and cutting action is repeated for the heat-sealed position.
