Description

Technical Field

[0001] This invention relates to the field of mixing device technology, specifically to an agricultural fertilizer mixing device. Background Technology

[0002] During the process of fertilizing plants, different crops have different nutritional needs, so a mixing device is needed to mix different types of waste materials.

[0003] A search revealed Chinese Patent Publication No. CN213528461U, which discloses a compound fertilizer mixing device, including a mixing tank, a mixing mechanism, and a crushing mechanism. The mixing tank has a feeding mixing mechanism on one side of its top, and a mixing chamber inside. The feeding mixing mechanism communicates with the mixing chamber. A mixing drive shaft is coaxially mounted in the mixing chamber, and four sets of mixing mechanisms are evenly arranged on the mixing drive shaft. A crushing mechanism is also fixed to the inner wall of the mixing chamber. This invention, by employing a vertical mixing method and using a specially shaped mixing wheel, significantly improves mixing efficiency compared to traditional mixing devices. Simultaneously, the crushing mechanism, in conjunction with the mixing device, effectively breaks down lumpy compound fertilizer particles adhering to the raw materials, solving the problem of large amounts of lumpy material mixed in with the compound fertilizer produced by traditional mixing devices that lack a crushing mechanism, thus improving the quality of the produced compound fertilizer.

[0004] The above-mentioned device effectively breaks down lumpy compound fertilizers that are stuck together in the mixed raw materials by cooperating with the crushing mechanism and the stirring device. However, when the fertilizer is being stirred, the fertilizer will continuously contact the annular inner wall of the stirring shell as it rotates around the axis. The centrifugal force of the rotating shell will cause the material to be squeezed, resulting in material residue and clumping. This will affect the normal rotation of the wheel, causing the rotating stirring mechanism to jam and causing unnecessary damage to the device. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an agricultural fertilizer mixing device that solves the problem that when fertilizer adheres to the inner wall of the mixing shell and clumps together, it affects the normal rotation of the rotary wheel, causing the rotating mixing mechanism to jam and resulting in unnecessary damage to the device.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an agricultural fertilizer mixing device, comprising a base, a support tube fixed to the upper side of the base, a housing rotatably connected to the outer wall of the support tube, a rotating rod rotatably connected to the inside of the support tube, a second motor fixed to one end of the support tube, the output end of the second motor fixedly located at one end of the rotating rod, a vertical frame fixed to the lower side of the support tube, the vertical frame located inside the housing, a rotating plate rotatably connected between the side walls of the vertical frame, a scraper rotatably connected to the outer wall of the rotating plate, a second synchronous belt disposed inside one of the vertical frames, the two ends of the second synchronous belt respectively fixed to the outer wall of the rotating rod and the rotating plate, multiple elastic ropes fixed between the scraper and the outer wall of the rotating plate, and the side of the scraper away from the rotating plate slidably connected to the inner wall of the housing.

[0007] The above technical solution drives the scraper to rotate via the output of the motor, which in turn stirs the fertilizer at the bottom of the shell vertically. The rotation of the shell improves the stirring efficiency of the device. Furthermore, the elastic rope ensures that the edges of the scraper maintain pressure on the inner wall of the shell, scraping away any clumps of fertilizer. This solves the problem in the prior art where fertilizer clumps on the inner wall of the mixing shell, affecting the normal rotation of the rotary wheel and causing the rotating stirring mechanism to jam, resulting in unnecessary damage to the device.

[0008] Preferably, the scraper has grooves on both sides of the side away from the rotating plate, and the inner wall of the groove on the side away from the rotating plate is at a predetermined distance from the side of the scraper away from the rotating plate.

[0009] Preferably, rectangular through holes are provided on both sides of the scraper, and the rectangular through holes are located between the groove and the rotating plate.

[0010] Preferably, conical rings are fixed to the inner walls of both sides of the housing, and a pre-set gap is provided between the side walls of the two conical rings and the two sides of the scraper.

[0011] Preferably, a first hanging rod is fixed side by side on the outer wall of the rotating plate near the vertical frame. The end of the first hanging rod away from the rotating plate is in contact with the outer wall of the vertical frame. An elastic rope is fixed on both sides of the first hanging rod. A second hanging rod is fixed on the end of the elastic rope away from the first hanging rod. One side of the second hanging rod is fixed to the outer wall of the scraper.

[0012] Preferably, both sides of the upper side of the base are fixed with support turntables, the outer walls of both ends of the support tube penetrate and are fixed to the inner wall of the support turntable, one side of the second motor is fixed to the outer wall of one of the support turntables, friction wheels are attached to the outer walls of both sides of the lower part of the housing, the two sides of the friction wheels are rotatably connected to the upper side of the base, the upper side of the base is fixed with a first motor, the output end of the first motor is fixed with a first synchronous belt, and the outer wall of the first synchronous belt is fixed to one side of one of the friction wheels.

[0013] Preferably, a feeding pipe is fixed to the outer wall of another supporting turntable, a hopper is fixed to the upper side of the feeding pipe, the other end of the supporting pipe is fixedly disposed at one end of the feeding pipe, and a feeding port is opened on the lower side of the supporting pipe inside the housing.

[0014] Preferably, the end of the rotating rod away from the second motor is fixed with an auger blade, and the end of the auger blade away from the second motor is located inside one end of the feed pipe.

A stirring component is fixed to the lower end of the first bevel gear. A crossbar is rotatably connected to the lower end of the stirring component. The two sides of the crossbar are fixed to the side wall between the two sides of the vertical frame. The discharge port is located between the shell and the stirring component away from the second motor.

[0016] Preferably, a discharge plate is installed on the outer wall of the housing, and a receiving box is slidably connected to the upper side of the base, with the receiving box located below the housing.

[0017] Working principle: During use, the output of motor two drives the rotating rod to rotate. Through the cooperation of synchronous belt two, it drives the rotating plate and the shell to rotate in opposite directions, which in turn drives the scraper to rotate, agitating the fertilizer at the bottom of the shell and further improving the efficiency of fertilizer mixing. At the same time, the tension of the elastic ropes on both sides of the scraper ensures that the scraper edges always exert pressure on the inner wall of the shell when agitating the fertilizer, scraping off the clumps of fertilizer. This solves the problem in the existing technology where when fertilizer sticks to the inner wall of the mixing shell and clumps together, it affects the normal rotation of the turntable, causing the rotating mixing mechanism to jam and resulting in unnecessary damage to the device.

[0018] This invention provides an agricultural fertilizer mixing device. It has the following beneficial effects:

[0019] 1. This invention drives the rotating plate and the housing to rotate in opposite directions through the output of motor two and the coordination of synchronous belt two. This, in turn, drives the scraper to rotate, stirring the fertilizer at the bottom of the housing. The tension of the elastic rope ensures that the edge of the scraper always applies pressure to the inner wall of the housing, repeatedly scraping away the clumps of fertilizer. This solves the problem in the prior art where, when fertilizer sticks to the inner wall of the mixing shell and clumps together, it affects the normal rotation of the turntable, causing the rotating mixing mechanism to jam and resulting in unnecessary damage to the device.

[0020] 2. The present invention drives the auger blades to rotate through the second output end of the motor, which transports the fertilizer into the shell for stirring. At the same time, the second output end of the motor also drives the stirring component to rotate, stirring, mixing and crushing the fertilizer inside the shell, thereby helping to improve the stirring efficiency of the device.

[0021] 3.

Detailed Implementation

[0031] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see the appendix Figure 1 Appendix Figure 3 Appendix Figure 5 and attached Figure 8 This invention provides an agricultural fertilizer mixing device, including a base 3, a support pipe 14 fixed to the upper side of the base 3, a housing 1 rotatably connected to the outer wall of the support pipe 14, a rotating rod 29 rotatably connected to the inside of the support pipe 14, a motor 7 fixed to one end of the support pipe 14, the output end of the motor 7 fixedly located at one end of the rotating rod 29, a vertical frame 15 fixed to the lower side of the support pipe 14, the vertical frame 15 located inside the housing 1, a rotating plate 22 rotatably connected between the side walls of the vertical frame 15, a scraper 17 rotatably connected to the outer wall of the rotating plate 22, a synchronous belt 24 disposed inside one of the vertical frames 15, the two ends of the synchronous belt 24 being fixed to the rotating rod 29 and the outer wall of the rotating plate 22 respectively, multiple elastic ropes 19 fixed between the scraper 17 and the outer wall of the rotating plate 22, and the side of the scraper 17 away from the rotating plate 22 being slidably connected to the inner wall of the housing 1.

[0033] Specifically, in the initial state, the elastic rope 19 is in a taut state, and the rotating rod 29 is rotatably connected to the inner wall of the support tube 14 through multiple bearings and is sealed. The synchronous belt 24 includes a belt connected end to end and two synchronous pulleys that rotate in contact with the inner side of the belt. The two synchronous pulleys are respectively fixed to the outer wall of the rotating rod 29 and the outer wall of the rotating plate 22 located inside the vertical frame 15. When the device is used to mix and stir fertilizer, the mixed fertilizer is put into the shell 1, and the base 3 provides support for the support tube 14. Through the rotation of the shell 1, the fertilizer inside the shell 1 is lifted and moved by the shell 1. Under the action of gravity, and through the relative fixation of the positions of the vertical frame 15 and the rotating plate 22, the effect of stirring fertilizer is achieved.

[0034] During the mixing process of this device, the rotating rod 29 is driven by the output of motor 7, and through the cooperation of synchronous belt 24, the rotating plate 22 and the shell 1 are driven to rotate in opposite directions, and the speed is greater than the rotation speed of the shell 1. This drives the scraper 17 to rotate, stirring the fertilizer at the bottom of the shell 1, further improving the efficiency of fertilizer mixing, and cleaning the inner wall of the shell 1, reducing the probability of fertilizer clumping on the inner wall of the shell 1.

[0035] When there are stubborn clumps of fertilizer on the inner wall of the shell 1, the elastic ropes 19 on both sides of the scraper 17 tighten, so that when the scraper 17 slides in contact with the inner wall of the shell 1, the edge of the scraper 17 always applies pressure to the inner wall of the shell 1, scraping off the clumps of fertilizer. As the shell 1 rotates continuously, the edge of the scraper 17 scrapes off the clumps of fertilizer on the inner wall of the shell 1 multiple times until the edge of the scraper 17 slides in contact with the inner wall of the shell 1. This solves the problem in the prior art that when fertilizer sticks to the inner wall of the mixing shell and clumps together, it affects the normal rotation of the rotary wheel, causing the rotating mixing mechanism to jam and causing unnecessary damage to the device.

[0036] Please see the appendix Figure 4 The scraper 17 has grooves 23 on both sides of the side away from the rotating plate 22. The inner wall of the groove 23 on the side away from the rotating plate 22 is at a predetermined distance from the side of the scraper 17 away from the rotating plate 22.

[0037] Specifically, by opening the groove 23, the edge of the scraper 17 that fits against the inner wall of the housing 1 shares one side with the inner wall of the groove 23, thereby forming a blade scraping effect; when the edge of the scraper 17 moves relative to the inner wall of the housing 1, the elastic rope 19 applies force to the scraper 17, so that the edge of the scraper 17 cleans the clump of fertilizer, thereby helping to improve the efficiency of scraping the clump of fertilizer.

[0038] Please see the appendix Figure 4 and attached Figure 5 The scraper 17 has rectangular through holes 21 on both sides, which are located between the groove 23 and the rotating plate 22.

[0039] Specifically, when the scraper 17 moves relative to the inner wall of the housing 1, the scraper 17 needs to overcome the pushing force of the fertilizer inside the housing 1 on the scraper 17, and the scraper 17 will squeeze the fertilizer during scraping, which may cause the fertilizer to clump together. Therefore, by setting the rectangular through hole 21, most of the fertilizer in contact with the scraper 17 can pass through the rectangular through hole 21 to the other side of the scraper 17 when the scraper 17 rotates, which reduces the squeezing of the fertilizer by the scraper 17, thereby helping to further improve the efficiency of scraping the clumped fertilizer.

[0040] Please see the appendix Figure 6 Both inner walls of the housing 1 are fixed with conical rings 13, and the side walls between the two conical rings 13 and the two sides of the scraper 17 are pre-set with a gap.

[0041] Specifically, the rotating plate 22 rotates between the side walls of the vertical frame 15 via the connecting rod, with one end inside the vertical frame 15. This causes one of the synchronous pulleys of the synchronous belt 24 to be fixed to the outer wall of the connecting rod. There is a sealing treatment between the connecting rod and the vertical frame 15. This causes the scraper 17 to be unable to clean the annular inner wall between the vertical frame 15 and the two sides of the shell 1 when cleaning the inner wall of the shell 1, which can easily create cleaning dead corners. By setting the conical ring 13, the annular inner wall of the shell 1 is set as a slope, which reduces the possibility of fertilizer clumping at the slope position during mixing, and allows the scraper 17 to cover the annular inner wall of the shell 1, thereby helping to improve the efficiency of scraping off clumped fertilizer.

[0042] Please see the appendix Figure 3 and attached Figure 4A first hanging rod 18 is fixed side by side on the outer wall of the rotating plate 22 near the vertical frame 15. The end of the first hanging rod 18 away from the rotating plate 22 is in contact with the outer wall of the vertical frame 15. An elastic rope 19 is fixed on both sides of the first hanging rod 18. A second hanging rod 20 is fixed on the end of the elastic rope 19 away from the first hanging rod 18. One side of the second hanging rod 20 is fixed to the outer wall of the scraper 17.

[0043] Specifically, the scraper 17 is rotatably connected to the two sides of the rotating plate 22 via a connecting rod between its two sides. There is a sealing treatment between the connecting rod and the rotating plate 22. Two hanging rods 18 are located on both sides of the connecting rod, and two hanging rods 20 are located on one side of the scraper 17. During the rotation of the scraper 17, there is a space between the scraper 17 and the rotating plate 22, which may allow clumps of fertilizer to enter and affect the operation of the structure. By having the end of the hanging rod 18 away from the rotating plate 22 attached to the outer wall of the vertical frame 15, and the elastic rope 19 connecting the hanging rods 18 and 20, the space between the two is further divided into smaller spaces. This achieves the tightening, resetting and force application of the scraper 17, while also preventing clumps of fertilizer from interfering with the rotation of the scraper 17.

[0044] Please see the appendix Figure 1 and attached Figure 2 The upper sides of the base 3 are fixed with support turntables 8. The outer walls of both ends of the support tube 14 pass through and are fixed to the inner wall of the support turntable 8. One side of the motor 7 is fixed to the outer wall of one of the support turntables 8. Friction wheels 2 are attached to the lower two outer walls of the housing 1. The two sides of the friction wheels 2 are rotatably connected to the upper side of the base 3. The upper side of the base 3 is fixed with a motor 4. The output end of the motor 4 is fixed with a timing belt 5. The outer wall of the timing belt 5 is fixed to one side of one of the friction wheels 2.

[0045] Specifically, the output of motor 4 drives a synchronous pulley of synchronous belt 5 to rotate. Through the transmission of the belt, friction wheel 2 rotates. Through the rolling contact between friction wheel 2 and the outer wall of housing 1, housing 1 rotates, thus realizing the function of housing 1 mixing fertilizer.

[0046] Please see the appendix Figure 2 and attached Figure 7 Another support turntable 8 has a feeding pipe 11 fixed to its outer wall. A hopper 10 is fixed to the upper side of the feeding pipe 11. The other end of the support pipe 14 is fixed to one end of the feeding pipe 11. The support pipe 14 has a feeding port 26 on its lower side inside the housing 1.

[0047] Specifically, when feeding fertilizer into the housing 1, the fertilizer can be put into the hopper 10, then the fertilizer passes through the discharge pipe 11, through the hollow support pipe 14, and enters the interior of the housing 1 from the discharge port 26, thus realizing the fertilizer feeding function of the device.

[0048] Please see the appendix Figure 7 and attached Figure 8 The end of the rotating rod 29 away from the motor 7 is fixed with an auger blade 25, and the end of the auger blade 25 away from the motor 7 is located inside one end of the feed pipe 11.

[0049] Specifically, when fertilizer enters the discharge pipe 11, due to the horizontal placement of the discharge pipe 11, some fertilizer remains in the discharge pipe 11 and cannot enter the housing 1. Therefore, when discharging, the auger blades 25 are driven by the output of motor 2 7 to rotate, and the fertilizer in the discharge pipe 11 is transported to the housing 1, thereby improving the discharge efficiency of the device.

[0050] Please see the appendix Figure 7 and attached Figure 8 Two second bevel gears 28 are fixed to the outer wall of the rotating rod 29. The teeth of the second bevel gears 28 are meshed with the first bevel gear 27. The lower end of the first bevel gear 27 is fixed with a stirring component 12. The lower end of the stirring component 12 is rotatably connected with a cross frame 16. The two sides of the cross frame 16 are fixed to the side wall between the two sides of the vertical frame 15. The discharge port 26 is located between the housing 1 and the stirring component 12 away from the motor 7.

[0051] Specifically, the mixing component 12, support tube 14, and cross frame 16 are all sealed. The gear ratio between the second bevel gear 28 and the first bevel gear 27 is preset. When mixing, the output of motor 27 drives the rotating rod 29 to rotate, causing the second bevel gear 28 to rotate, which in turn drives the first bevel gear 27 to rotate. This causes the two mixing components 12 to rotate in a preset direction, mixing, stirring, and crushing the fertilizer inside the shell 1, thereby improving the mixing efficiency of the device.

[0052] Please see the appendix Figure 1 The outer wall of the housing 1 is equipped with a discharge plate 9, and the upper side of the base 3 is slidably connected to a receiving box 6, which is located below the housing 1.

[0053] Specifically, after the mixing is finished, the discharge plate 9 is rotated to the bottom of the shell 1 to open the discharge plate 9, so that the fertilizer inside the shell 1 enters the concave collection box 6, thereby realizing the discharge function of the device.

[0054] Work process: When using this device, fertilizer is put into the hopper 10 and enters the discharge pipe 11. Driven by the output end of motor 27, the auger blade 25 is rotated at a certain appropriate speed, and the fertilizer inside the discharge pipe 11 is sent into the housing 1 through the discharge port 26, thus realizing the function of the device in discharging fertilizer.

[0055] After the feeding is finished, the output of motor 27 switches the speed, and through the engagement of the teeth of the first bevel gear 27 and the second bevel gear 28, motor 27 drives the stirring piece 12 to rotate at a suitable speed inside the shell 1, stirring the fertilizer inside the shell 1 in the horizontal direction. At the same time, it can also break up the clumps of fertilizer.

[0056] Meanwhile, the drive at the output end of motor 27, through the cooperation of synchronous belt 24, causes the rotating plate 22 to rotate, which in turn drives the scraper 17 to rotate, stirring the fertilizer inside the shell 1 vertically. When the edge of the scraper 17 contacts the inner wall of the shell 1, the rotational connection between the scraper 17 and the rotating plate 22, and the cooperation of the elastic rope 19, ensure that the edge of the scraper 17 always exerts pressure on the inner wall of the shell 1, which can scrape off the clumps of fertilizer. This solves the problem in the prior art where, when fertilizer sticks to the inner wall of the mixing shell and clumps together, it affects the normal rotation of the turntable, causing the rotating mixing mechanism to jam and resulting in unnecessary damage to the device.

[0057] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
