Description

Technical Field

[0001] The present invention relates to the technical field of fertilizer production, and particularly to a mixing device for polyglutamic acid-containing fertilizers and a production method thereof. Background Art

[0002] Polyglutamic acid-containing fertilizers are a new type of fertilizer. Polyglutamic acid is a natural polymer produced by microbial fermentation, which has excellent water retention and ion adsorption capabilities. Polyglutamic acid-containing fertilizers can effectively improve crop yield and quality, while reducing environmental impact, and are applicable to a variety of agricultural and horticultural scenarios through their water retention, slow-release nutrient, and soil improvement characteristics.

[0003] Currently, when producing polyglutamic acid-containing fertilizers, a mixing device is usually used to uniformly mix polyglutamic acid with other fertilizer components to ensure stable product quality. During the mixing process, the fertilizers accumulated at the bottom of the device are difficult to be lifted up and come into full contact with polyglutamic acid, which increases the mixing time and affects the mixing uniformity. Moreover, when adding polyglutamic acid, it is necessary to measure and proportion according to the total amount of fertilizers. Secondly, the measured fertilizers and polyglutamic acid are added into the device for mixing together. Since polyglutamic acid will concentrate in a small area, the fertilizers in this area will quickly absorb the polyglutamic acid, making it difficult for the measured polyglutamic acid to come into uniform contact with the fertilizers inside the device, thereby affecting the product quality.

[0011] As a further solution of the present invention, the mixing assembly includes a top plate which is fixedly connected to the outside of the feeding assembly.

On both sides of the bottom of the top plate, rotating shafts are respectively fixedly connected, and the two rotating shafts are respectively located on both sides of the conveying cylinder. Two mixing vanes are fixed outside the rotating shafts. A baffle plate is arranged between the two mixing vanes on the same side, and the baffle plate is fixed to the inner wall of the mixing box.

[0012] As a further solution of the present invention, the feeding assembly includes a motor which is installed on a fixed frame. A fixed shaft is fixedly connected to the output shaft of the motor. The top end of the fixed shaft is installed in the fixed frame through a shaft sleeve. A spiral blade is arranged outside the fixed shaft, and the spiral blade is located inside the conveying cylinder. A spiral rod is fixedly connected to the bottom end of the fixed shaft. An outlet valve pipe is arranged below the spiral rod, and the outlet valve pipe is installed at the bottom of the mixing box. Supporting legs are respectively installed at the four corners of the bottom of the mixing box, and the bottom of the inner wall of the mixing box is designed as an inverted cone.

[0013] A production method of a mixing device for a polyglutamic acid-containing fertilizer, the production method comprising the following steps:

[0014] In the production work of the polyglutamic acid-containing fertilizer, open the lid at the top of the feed cylinder, close the outlet valve pipe at the bottom of the mixing box. Secondly, place the metered and proportioned fertilizer and polyglutamic acid into the mixing box and the feed cylinder respectively. Part of the polyglutamic acid enters the turnover box at the bottom of the feed cylinder. Then install the lid on the top of the feed cylinder to prevent the polyglutamic acid from spilling during the movement of the feed cylinder. After completing the production preparation work, start the motor;

[0015] The motor works and drives the fixed shaft to rotate. The fixed shaft drives the two feed cylinders to rotate through a connecting plate. Since the outer wall of the fixed shaft is fixed to the top plate, the two ends of the top plate drive the rotating ring to rotate inside the bearing seat. Also, since the outer wall of the feed cylinder is fixed to the inner wall of the rotating ring through a fixing block, the rotating ring and the feed cylinder can rotate synchronously. During the rotation of the feed cylinder, the turnover box below it drives the connecting shaft in the feeding component to revolve around the center of the mixing box. The connecting shaft drives the gear to move on the toothed disc. Since the toothed disc is meshed with the gear, while the connecting shaft revolves around the center of the mixing box, the gear drives the connecting shaft to rotate. The connecting shaft drives a plurality of feeding vanes to rotate in the turnover box. During the rotation of the feeding vanes, the polyglutamic acid entering the turnover box can be guided below the turnover box and discharged from the outlet, so that the polyglutamic acid falls into the mixing box, achieving the purpose of quantitatively adding materials to the fertilizer. Since the feed cylinder moves around the edge inside the mixing box during the rotation of the guiding vane, the polyglutamic acid can be quantitatively added to the mixing box from multiple directions, enabling the polyglutamic acid to be evenly contacted with the fertilizer;

[0016] During the rotation of the fixed shaft, it can drive the spiral blade to rotate. Since the spiral blade is located inside the conveying cylinder and extends to the bottom inside the mixing box, the fertilizer at the bottom inside the mixing box comes into contact with the spiral blade. During the rotation of the spiral blade, it can convey the fertilizer upward, enabling the fertilizer to move upward inside the conveying cylinder. Moreover, the through holes opened on the outside of the conveying cylinder improve the air permeability and conductivity of the internal fertilizer, allowing polyglutamic acid and the fertilizer to come into full contact until the spiral blade discharges the fertilizer from the opening at the top of the conveying cylinder. Thus, it can turn the fertilizer in the lower layer inside the mixing box to the upper layer, cooperate with the distributing piece to discharge polyglutamic acid from multiple directions and contact with the fertilizer, and the fertilizer that was previously in the upper layer is transferred to the lower layer inside the mixing box. In this way, the cycle increases the fluidity of the fertilizer inside the mixing box, thereby improving the mixing effect;

[0017] At the same time, the fixed shaft drives the two rotating shafts to rotate through the top plate, and the rotating shafts drive the mixing pieces to revolve around the center of the mixing box, enabling the mixing pieces to mix and stir the fertilizer between the mixing box and the conveying cylinder. Since there is a baffle plate between the two mixing pieces on the same side, when the fertilizer is transferred as the mixing pieces rotate, the baffle plate can resist part of the fertilizer, forming a reverse force with the mixing pieces. And the baffle plate is inclined in the mixing box, which can serve the purpose of guiding the fertilizer and further increasing the fluidity between the fertilizer layers inside the mixing box;

[0018] After the mixing work is completed, open the discharge valve pipe at the bottom of the mixing box. Since the bottom of the inner wall of the mixing box is designed as an inverted cone, the fertilizer can be concentrated towards the top of the discharge valve pipe. Secondly, control the motor to reverse. The motor drives the spiral blade to reverse through the fixed shaft, enabling the spiral blade to convey the fertilizer inside the conveying cylinder downward and discharge it. At the same time, when the fixed shaft drives the screw rod to reverse, the screw rod can convey the fertilizer downward until the fertilizer is discharged from the discharge valve pipe, preventing the discharge valve pipe from being blocked and affecting the discharge, and finally completing the production work of the polyglutamic acid-containing fertilizer.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. The present invention controls the operation of the motor and drives the fixed shaft to rotate. The fixed shaft drives two material cylinders to rotate through a connecting plate. Since the outer wall of the fixed shaft is fixed to the top plate, the two ends on the top plate drive the rotating ring to rotate inside the bearing seat. Also, since the outer wall of the material cylinder is fixed to the inner wall of the rotating ring through a fixed block, the rotating ring and the material cylinder can rotate synchronously. During the rotation of the material cylinder, the turnover box below it drives the connecting shaft in the material distribution component to revolve around the center of the mixing box. The connecting shaft drives the gear to move on the toothed disc. Since the toothed disc is meshed with the gear, while the connecting shaft revolves around the center of the mixing box, the gear drives the connecting shaft to rotate. The connecting shaft drives a plurality of material distribution plates to rotate in the turnover box. During the rotation of the material distribution plates, the polyglutamic acid entering the turnover box can be introduced below the turnover box and discharged from the discharge port, so that the polyglutamic acid falls into the mixing box, achieving the purpose of quantitatively adding materials to the fertilizer. Since the material guide plate moves around the edge inside the mixing box during rotation, the polyglutamic acid can be quantitatively added to the mixing box from multiple directions, abandoning the traditional method of adding the measured fertilizer and polyglutamic acid into the equipment for mixing together, preventing the fertilizer in the area from quickly absorbing the polyglutamic acid due to the concentration of the polyglutamic acid in a small area, enabling the measured polyglutamic acid to be evenly contacted with the fertilizer inside the mixing box, and thus ensuring the quality of the product.

[0021] 2. The present invention drives the spiral blade to rotate through the fixed shaft, so that the fertilizer at the bottom inside the mixing box contacts the spiral blade. During the rotation of the spiral blade, the fertilizer can be conveyed upward, enabling the fertilizer to move upward inside the conveying cylinder. The through holes provided on the outside of the conveying cylinder improve the air permeability and conductivity of the internal fertilizer, enabling the polyglutamic acid and the fertilizer to fully contact until the spiral blade discharges the fertilizer from the opening at the top of the conveying cylinder. Thus, the fertilizer in the lower layer inside the mixing box can be turned to the upper layer, cooperating with the material distribution plates to export the polyglutamic acid from multiple directions and contact the fertilizer. The fertilizer that was previously in the upper layer is transferred to the lower layer inside the mixing box. In this way, the cycle is repeated, increasing the fluidity of the fertilizer inside the mixing box. At the same time, the rotating shaft drives the mixing blade to revolve around the center of the mixing box, enabling the mixing blade to mix and stir the fertilizer between the mixing box and the conveying cylinder. When the fertilizer is transferred along with the rotation of the mixing blade, the baffle can resist a part of the fertilizer, forming a reverse force with the mixing blade. And the baffle is inclined in the mixing box, which can play the role of guiding the fertilizer, further increasing the fluidity between the fertilizer layers inside the mixing box and further improving the mixing effect.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0034] Please refer to Figures 1-8 , the present invention provides a technical solution:

[0035] A mixing device containing polyglutamic acid fertilizer includes a mixing box 1, a fixing frame 2 is fixedly connected to the mixing box 1, a support assembly 3 is arranged below the fixing frame 2, the support assembly 3 is installed at the opening at the top of the mixing box 1, and the support assembly 3 includes a bearing seat 301, the bearing seat 301 is clamped at the opening at the top of the mixing box 1, a swivel 302 is sleeved in the bearing seat 301, the swivel 302 is overlapped on the inner wall of the mixing box 1, and the inner wall of the swivel 302 is fixed to two material storage assemblies 6. The arrangement of the bearing seat 301 reduces the friction force generated by the swivel 302 when rotating inside the mixing box 1, and the swivel 302 will not separate from the bearing seat 301, thereby improving the stability of the movement of the two material storage assemblies 6 above the swivel 302.

[0036] As a further solution of the present invention, a toothed disc 4 is provided below the support assembly 3, and the toothed disc 4 is fixedly connected to the inner wall of the mixing box 1. Two material distribution components 5 are respectively meshed and connected on both sides of the toothed disc 4, and the material distribution components 5 are arranged through the support assembly 3. The material distribution component 5 includes a connecting shaft 501, and the connecting shaft 501 is arranged through the rotating ring 302 through a shaft sleeve. One end of the connecting shaft 501 passes through the rotating ring 302 and is fixedly connected with a gear 502, and the gear 502 is meshed and connected to the toothed disc 4; the other end of the connecting shaft 501 is installed at the bottom of the storage assembly 6 through a shaft sleeve, and the connecting shaft 501 is provided with a plurality of material distribution sheets 503, and the plurality of material distribution sheets 503 are located at the bottom of the inner wall of the storage assembly 6.

[0037] Because the toothed disc 4 is meshed with the gear 502, while the connecting shaft 501 revolves around the center of the mixing box 1, the gear 502 drives the connecting shaft 501 to rotate, and the connecting shaft 501 drives multiple dividing pieces 503 to rotate, so that the dividing pieces 503 can export the fertilizer inside the storage component 6 in equal amounts.

[0038] As a further solution of the present invention, a connecting plate 7 is fixedly connected between the two storage assemblies 6, one side of the storage assemblies 6 is fixedly connected to the inner wall of the support assembly 3, and the two storage assemblies 6 are respectively located on both sides of the fixed frame 2. The storage assembly 6 includes a barrel 601, a barrel cover 602 is installed on the top of the barrel 601, a fixed block 603 is fixedly connected to the outer wall of the barrel 601, and the fixed block 603 is fixed to the inner wall of the rotating ring 302, a turnover box 604 is installed at the bottom of the barrel 601, a discharge port 605 is provided at the bottom of the turnover box 604, and a plurality of material dividing sheets 503 are located in the turnover box 604, and a side of the outer wall of the barrel 601 away from the fixed block 603 is fixed to the connecting plate 7.

[0039] Since the outer wall of the barrel 601 is fixed to the inner wall of the swivel ring 302 through the fixing block 603, the swivel ring 302 and the barrel 601 can rotate synchronously. During the rotation of the barrel 601, the turnover box 604 below it drives the connecting shaft 501 to revolve around the center of the mixing box 1. The connecting shaft 501 drives the distributing plate 503 to import polyglutamic acid below the turnover box 604 and discharge it from the discharge port 605 during rotation, so that the polyglutamic acid falls into the mixing box 1, achieving the purpose of quantitatively adding materials to the fertilizer.

[0040] As a further solution of the present invention, a material guiding component 8 is installed in the mixing box 1, and a mixing component 9 is arranged above the material guiding component 8. The mixing component 9 is located in the mixing box 1. The material guiding component 8 includes a conveying cylinder 801. Four extension plates 803 are fixed to the bottom of the outer wall of the conveying cylinder 801, and the four extension plates 803 are fixedly connected to the lower part of the inner wall of the mixing box 1; a number of through holes 802 are opened on the outside of the conveying cylinder 801. The through holes 802 opened on the outside of the conveying cylinder 801 improve the air permeability and conductivity of the fertilizer inside, enabling the polyglutamic acid and the fertilizer to come into full contact.

[0041] The mixing component 9 includes a top plate 901. The two ends of the top plate 901 are fixed to the inner wall of the swivel ring 302. Two rotating shafts 902 are respectively fixed to both sides of the bottom of the top plate 901, and the two rotating shafts 902 are respectively located on both sides of the conveying cylinder 801. Two mixing plates 903 are fixed to the outside of the rotating shafts 902. A baffle plate 11 is arranged between the two mixing plates 903 on the same side, and the baffle plate 11 is fixed to the inner wall of the mixing box 1.

[0042] The rotating shaft 902 drives the mixing plate 903 to revolve around the center of the mixing box 1, enabling the mixing plate 903 to mix and stir the fertilizer between the mixing box 1 and the conveying cylinder 801. When the fertilizer is transferred along with the rotation of the mixing plate 903, the baffle plate 11 can block a part of the fertilizer, and the baffle plate 11 is inclined in the mixing box 1, which can play the role of guiding the fertilizer, increasing the fluidity between the layers of fertilizer in the mixing box 1 and improving the mixing effect.

[0043] As a further solution of the present invention, a feeding component 10 is provided through the top of the top plate 901. The feeding component 10 includes a motor 101. The motor 101 is installed on the fixing frame 2. A fixing shaft 102 is fixedly connected to the output shaft of the motor 101. A connecting plate 7 is fixed outside the fixing shaft 102. The bottom of the fixing shaft 102 penetrates through the fixing shaft 102 and extends to the bottom of the inner wall of the mixing tank 1. The top end of the fixing shaft 102 is installed in the fixing frame 2 through a bushing. A spiral blade 103 is provided outside the fixing shaft 102. The spiral blade 103 is located inside the conveying cylinder 801. A spiral rod 104 is fixedly connected to the bottom end of the fixing shaft 102. A discharge valve pipe 12 is provided below the spiral rod 104. During the process of the fixing shaft 102 driving the spiral rod 104 to reverse, the spiral rod 104 can convey the fertilizer downward until the fertilizer is discharged from the discharge valve pipe 12, preventing the discharge valve pipe 12 from being blocked and affecting the discharge. The discharge valve pipe 12 is installed at the bottom of the mixing tank 1, and support legs 13 are respectively installed at the four corners of the bottom of the mixing tank 1. The bottom of the inner wall of the mixing tank 1 is designed as an inverted cone.

[0044] During the rotation process, the spiral blade 103 can convey the fertilizer upward, enabling the fertilizer to move upward inside the conveying cylinder 801 until the spiral blade 103 discharges the fertilizer from the opening at the top of the conveying cylinder 801. Furthermore, the fertilizer in the lower layer of the mixing tank 1 can be turned to the upper layer, further increasing the fluidity of the fertilizer in the mixing tank 1.

[0045] Based on the above, the traditional method of adding the metered fertilizer and polyglutamic acid into the equipment for mixing together is abandoned to prevent the fertilizer in a small area from quickly absorbing the polyglutamic acid due to the concentration of polyglutamic acid in a small area, enabling the metered polyglutamic acid to be evenly contacted with the fertilizer inside the mixing tank 1.

[0046] A production method of a mixing device for a polyglutamic acid-containing fertilizer, the production method includes the following steps:

[0047] During the production work of the polyglutamic acid-containing fertilizer, open the lid 602 at the top of the material cylinder 601, close the discharge valve pipe 12 at the bottom of the mixing tank 1. Secondly, place the metered and proportioned fertilizer and polyglutamic acid into the mixing tank 1 and the material cylinder 601 respectively. Part of the polyglutamic acid enters the turnover box 604 at the bottom of the material cylinder 601. Then install the lid 602 on the top of the material cylinder 601, thereby preventing the polyglutamic acid from spilling during the movement of the material cylinder 601. After completing the preparatory work for production, start the motor 101;

[0048] The motor 101 operates and drives the fixed shaft 102 to rotate. The fixed shaft 102 then drives the two material cylinders 601 to rotate through the connecting plate 7. Since the outer wall of the fixed shaft 102 is fixed to the top plate 901, the two ends on the top plate 901 drive the rotating ring 302 to rotate inside the bearing block 301. Also, since the outer wall of the material cylinder 601 is fixed to the inner wall of the rotating ring 302 through the fixing block 603, the rotating ring 302 and the material cylinder 601 can rotate synchronously. During the rotation of the material cylinder 601, the turnover box 604 below it drives the connecting shaft 501 in the material distribution assembly 5 to revolve around the center of the mixing box 1. The connecting shaft 501 drives the gear 502 to move on the toothed disc 4. Since the toothed disc 4 is meshed with the gear 502, while the connecting shaft 501 revolves around the center of the mixing box 1, the gear 502 drives the connecting shaft 501 to rotate on its own axis. The connecting shaft 501 drives multiple material distribution blades 503 to rotate inside the turnover box 604. During the rotation of the material distribution blades 503, the polyglutamic acid entering the turnover box 604 can be guided to the lower part of the turnover box 604 and discharged from the discharge port 605, causing the polyglutamic acid to fall into the mixing box 1, achieving the purpose of quantitatively adding materials to the fertilizer. Since the material cylinder 601 moves around the edge inside the mixing box 1 during the rotation of the guiding blade, the polyglutamic acid can be quantitatively added to the mixing box 1 from multiple directions, enabling the polyglutamic acid to come into uniform contact with the fertilizer;

[0049] During the rotation of the fixed shaft 102, it can drive the spiral blade 103 to rotate. Since the spiral blade 103 is located inside the conveying cylinder 801 and extends to the bottom inside the mixing box 1, the fertilizer at the bottom inside the mixing box 1 comes into contact with the spiral blade 103. During the rotation of the spiral blade 103, it can convey the fertilizer upward, enabling the fertilizer to move upward inside the conveying cylinder 801. Moreover, the through holes 802 opened on the outside of the conveying cylinder 801 improve the air permeability and conductivity of the internal fertilizer, enabling the polyglutamic acid and the fertilizer to come into full contact until the spiral blade 103 discharges the fertilizer from the opening at the top of the conveying cylinder 801, thereby being able to turn the fertilizer in the lower layer inside the mixing box 1 to the upper layer, cooperating with the material distribution blades 503 to guide the polyglutamic acid out from multiple directions and come into contact with the fertilizer. The fertilizer that was previously in the upper layer then transfers to the lower layer inside the mixing box 1. In this way, the cycle increases the fluidity of the fertilizer inside the mixing box 1, thereby improving the mixing effect;

[0050] Meanwhile, the fixed shaft 102 drives the two rotating shafts 902 to rotate through the top plate 901. The rotating shafts 902 drive the mixing blades 903 to revolve around the center of the mixing tank 1, so that the mixing blades 903 can mix and stir the fertilizer between the mixing tank 1 and the conveying cylinder 801. Since a baffle plate 11 is provided between the two mixing blades 903 on the same side, the baffle plate 11 can resist a part of the fertilizer when the fertilizer is transferred along with the rotation of the mixing blades 903, so as to form a reverse acting force with the mixing blades 903. Moreover, the baffle plate 11 is inclined in the mixing tank 1, which can play the role of guiding the fertilizer and further increase the fluidity between the fertilizers in each layer in the mixing tank 1;

[0051] After the mixing work is completed, open the discharge valve pipe 12 at the bottom of the mixing tank 1. Since the bottom of the inner wall of the mixing tank 1 is designed as an inverted cone, the fertilizer can be concentrated at the top of the discharge valve pipe 12. Secondly, control the motor 101 to reverse. The motor 101 drives the spiral blade 103 to reverse through the fixed shaft 102, so that the spiral blade 103 can convey the fertilizer inside the conveying cylinder 801 downward and discharge it. At the same time, when the fixed shaft 102 drives the screw rod 104 to reverse, the screw rod 104 can convey the fertilizer downward until the fertilizer is discharged from the discharge valve pipe 12, preventing the discharge valve pipe 12 from being blocked and affecting the discharge, and finally completing the production work of the polyglutamic acid-containing fertilizer.

A method for producing a mixing device containing polyglutamic acid fertilizer, according to any one of claims 1 to 7, characterized in that: The production method comprises the following steps: During the production of the polyglutamic acid-containing fertilizer, the barrel cover (602) on the top of the barrel (601) is opened, and the discharge valve tube (12) at the bottom of the mixing box (1) is closed. Then, the fertilizer and polyglutamic acid with a good metered ratio are placed in the mixing box (1) and the barrel (601) respectively, and part of the polyglutamic acid enters the turnover box (604) at the bottom of the barrel (601). Then, the barrel cover (602) is installed on the top of the barrel (601) to prevent the polyglutamic acid from being spilled during the movement of the barrel (601). After completing the preparation work for production, the motor (101) is started; The motor (101) works and drives the fixed shaft (102) to rotate. The fixed shaft (102) drives the two barrels (601) to rotate through the connecting plate (7). Since the outer wall of the fixed shaft (102) is fixed to the top plate (901), the two ends on the top plate (901) drive the rotating ring (302) to rotate inside the bearing seat (301). Since the outer wall of the barrel (601) is fixed to the inner wall of the rotating ring (302) through the fixing block (603), the rotating ring (302) and the barrel (601) can rotate synchronously. During the rotation of the barrel (601), the turnover box (604) below it drives the connecting shaft (501) in the material distribution component (5) to revolve around the center of the mixing box (1). The connecting shaft (501) drives the gear (502) to move on the toothed disc (4). Because the toothed disc (4) is meshed with the gear (502), while the connecting shaft (501) revolves around the center of the mixing box (1), the gear (502) drives the connecting shaft (501) to rotate, and the connecting shaft (501) drives the plurality of material dividing sheets (503) to rotate in the turnover box (604). During the rotation process, the material dividing sheets (503) can guide the polyglutamic acid entering the turnover box (604) to the bottom of the turnover box (604) and discharge it from the discharge port (605), so that the polyglutamic acid falls into the mixing box (1), thereby achieving the purpose of quantitatively adding the fertilizer to the fertilizer. During the rotation process of the material guiding sheet, the barrel (601) moves around the edge of the mixing box (1), so that the polyglutamic acid can be quantitatively added to the mixing box (1) from multiple directions, so that the polyglutamic acid is in uniform contact with the fertilizer. The fixed shaft (102) can drive the spiral blade (103) to rotate during the rotation process. Since the spiral blade (103) is located in the conveying cylinder (801) and extends to the bottom of the mixing box (1), the fertilizer at the bottom of the mixing box (1) contacts the spiral blade (103). The spiral blade (103) can convey the fertilizer upward during the rotation process, so that the fertilizer can move upward inside the conveying cylinder (801). The through hole (802) provided on the outside of the conveying cylinder (801) improves the internal The air permeability and conductivity of the fertilizer are improved so that the polyglutamic acid and the fertilizer can fully contact each other until the spiral blade (103) discharges the fertilizer from the opening at the top of the conveying cylinder (801), thereby turning the fertilizer in the lower layer of the mixing box (1) to the upper layer, and cooperating with the material dividing sheet (503) to guide the polyglutamic acid from multiple directions and contact the fertilizer, and the fertilizer previously in the upper layer is transferred to the lower layer of the mixing box (1), and the cycle is repeated in this way, thereby increasing the fluidity of the fertilizer in the mixing box (1) and improving the mixing effect; At the same time, the fixed shaft (102) drives the two rotating shafts (902) to rotate through the top plate (901), and the rotating shaft (902) drives the mixing piece (903) to revolve around the center of the mixing box (1), so that the mixing piece (903) can mix and stir the fertilizer between the mixing box (1) and the conveying cylinder (801). Because a baffle plate (11) is provided between the two mixing pieces (903) on the same side, the baffle plate (11) can resist a part of the fertilizer when the fertilizer is transferred with the rotation of the mixing piece (903), so that it forms a reverse force with the mixing piece (903), and the baffle plate (11) is arranged obliquely in the mixing box (1), which can guide the fertilizer and further increase the fluidity between the fertilizer layers in the mixing box (1); After the mixing work is completed, the discharge valve tube (12) at the bottom of the mixing box (1) is opened. Since the bottom of the inner wall of the mixing box (1) is designed in an inverted cone shape, the fertilizer can be concentrated on the top of the discharge valve tube (12). Then, the motor (101) is controlled to reverse, and the motor (101) drives the spiral blade (103) to reverse through the fixed shaft (102), so that the spiral blade (103) can convey the fertilizer inside the conveying cylinder (801) downward and discharge it. At the same time, in the process of the fixed shaft (102) driving the spiral rod (104) to reverse, the spiral rod (104) can convey the fertilizer downward until the fertilizer is led out of the discharge valve tube (12), so as to prevent the discharge valve tube (12) from being blocked and affecting the discharge, and finally complete the production of the polyglutamic acid fertilizer.
