Description

Technical Field

[0001] The present invention relates to the technical field of fertilizer mixing, and particularly relates to a fertilizer stirring device. Background Art

[0002] A fertilizer stirring device is used to mix different types of fertilizer raw materials to meet the nutritional requirements of specific crops. Since different crops have different nutrient requirements, and the nutrient requirements of the same crop also vary at different growth stages, when pouring different types of fertilizer raw materials into the stirring device for mixing, it is necessary to quantitatively feed according to the ratio of the fertilizer raw materials.

[0003] Chinese Patent with publication number CN205796991U discloses a fertilizer blending device, which includes a conveying device and a mixer fixed below a bracket. The conveying device includes a first hopper. The discharge end of the first hopper is connected to the feed end of a bucket elevator through a chute. The discharge end of the bucket elevator is connected to a storage weighing device, and the storage weighing device is connected to the mixer through a pipeline.

[0004] In the above patent, fertilizers are mechanically poured into the first hopper. The fertilizers flow through the chute to the feed end of the bucket elevator, and then flow into a crusher from the discharge end of the bucket elevator to be broken. After being broken, the fertilizers with uniform particles flow into a storage tank. The electric control valve of the storage tank is opened, and the fertilizers in the storage tank are weighed by a weighing device and then flow into the mixer, and the mixer stirs to produce blended fertilizers.

[0005] The above patent requires the cooperation of a first hopper, a bucket elevator, a crusher, a storage tank and a weighing device to lift and quantitatively feed fertilizers. There are many devices involved, which require a large amount of space and a relatively large amount of manual input, resulting in a relatively high production cost of fertilizers.

[0006] Therefore, there is a need in the art for a fertilizer stirring device to solve the above problems. Summary of the Invention

[0007] The present invention provides a fertilizer stirring device, aiming to solve the problems in the related art that the fertilizer stirring device has a single function and requires the cooperation of many devices for quantitative feeding of fertilizer raw materials, resulting in a large floor area, a relatively large labor input cost, and a relatively high production cost of fertilizers.

[0008] A fertilizer stirring device of the present invention includes a horizontal stirring cylinder and a stirring assembly arranged in the stirring cylinder. At least two hoppers are fixedly installed at the top of the stirring cylinder. A first baffle and a second baffle are arranged up and down in the hopper. A distributing cylinder is rotatably connected between the first baffle and the second baffle. A plurality of bins are equally divided in the distributing cylinder. A first material dropping port is opened on the first baffle, and a second material dropping port which is vertically staggered with the first material dropping port is opened on the second baffle; The mixing drum is provided with a driving assembly for driving the material distribution drum to rotate. When the hopper is opposite to the first drop opening, the fertilizer raw materials in the hopper enter the hopper. When the hopper is opposite to the second drop opening, the fertilizer raw materials in the hopper enter the mixing drum. The hopper is provided with a crushing rod 1 and a crushing rod 2 which are distributed up and down. The crushing rod 1 is fixedly connected to the hopper, and the crushing rod 2 is connected to a material distribution cylinder. When the material distribution cylinder drives the crushing rod 2 to pass under the crushing rod 1, the fertilizer raw materials in the hopper are sheared and crushed.

[0009] The present invention drives the distribution barrel to rotate through a driving component, so that when the silo passes through the second drop opening, the fertilizer raw materials are lowered. By controlling the rotation angle of the distribution barrel, a corresponding number of silos pass through the drop opening in sequence, and the fertilizer raw materials can be quantitatively lowered. Moreover, the present invention drives the distribution barrels in a plurality of hoppers to rotate at different angles, so as to achieve quantitative lowering of different fertilizer raw materials and proportioning of different fertilizer raw materials. The present invention arranges the crushing rod one and the crushing rod two up and down, and when the crushing rod two passes under the crushing rod one, the fertilizer raw materials in the hopper are sheared and crushed, so that the fertilizer agglomeration in the hopper is reduced, so that the fertilizer can smoothly enter the silo and be fully mixed after entering the mixing barrel.

[0010] Preferably, the breaker rod one is fixedly connected to a mounting ring, the mounting ring is coaxially arranged with the material distribution barrel, a plurality of breaker rods three are evenly spaced on the mounting ring, the breaker rod three is rotatably connected to the mounting ring, and a driving component is arranged in the hopper to drive the plurality of breaker rods three to rotate synchronously upward or downward.

[0011] During the repeated up and down swinging of the breaker rod three, the fertilizer raw materials in the hopper can be moved, which helps the fertilizer raw materials to quickly enter the silo of the distribution barrel; and when all the breaker rods three rotate upward at the same time, the space between the breaker rods three and the angle between the breaker rods three and the installation shaft will gradually become smaller, which can break up the larger volume of fertilizer lumps in the hopper.

[0012] Preferably, the distributing barrel is fixedly connected with a coaxially arranged mounting shaft, the mounting shaft vertically penetrates baffle plate 1, the crushing rod 2 is fixedly connected to the mounting shaft, and the driving component is arranged on the mounting shaft.

[0013] Preferably, the driving component includes a mounting sleeve and a connecting rod, the mounting sleeve is sleeved on the outer periphery of the mounting shaft, the connecting rod is hinged between the mounting sleeve and the corresponding breaking rod three, a guide groove is opened on the outer periphery of the mounting shaft, a guide block extending into the guide groove is fixedly connected to the mounting sleeve, when the mounting shaft rotates, the guide groove pushes the guide block to drive the mounting sleeve to move up and down, and the mounting sleeve drives the breaking rod three to rotate up and down through the connecting rod.

[0014] The up-and-down rotation of the crushing rod three is driven by the cooperation of the guiding groove and the guiding block, saving the cost of separately arranging a driving source for the crushing rod three. Moreover, during the process of the connecting rod driving the crushing rod three to move, the included angle between the connecting rod and the crushing rod three also changes. Therefore, it can also extrude and crush the fertilizer raw material agglomerates located between the connecting rod and the crushing rod three.

[0015] Preferably, the driving assembly includes a driving component one, driving components two corresponding to each material distribution cylinder, a gear set, and a gear ring. The gear ring is fixedly connected to the outer periphery of the material distribution cylinder. The gear set includes a rotating shaft and a plurality of transmission gears arranged on the rotating shaft. The rotating shaft is rotatably connected to the mixing cylinder. The number of teeth of the plurality of transmission gears gradually decreases from bottom to top, and the tooth parts of the plurality of transmission gears correspond up and down. The driving component one drives the rotating shaft to drive the transmission gears to rotate. The transmission gears drive the gear ring and the material distribution cylinder meshed with them to rotate. The driving component two drives the transmission gears to move up and down to replace the transmission gears meshed with the gear ring, so as to change the rotation angle of the gear ring and the material distribution cylinder.

[0016] By driving all the transmission gears to move up and down by the driving component two to replace the transmission gears meshed with the gear ring, the effect of changing the ratio of fertilizer raw materials can be achieved.

[0017] Preferably, the driving component one includes a driving motor, a gear one, and gears two corresponding to each material distribution cylinder. The driving motor is fixedly installed on the mixing cylinder. The gear one is fixedly connected to the output end of the driving motor. The gear two is fixedly connected to the corresponding rotating shaft. The gear one is meshed with the gear two. The driving motor drives the gear one to drive the gear two to rotate. The gear two drives the rotating shaft and the transmission gears to rotate.

[0018] Preferably, the transmission gear is slidably connected to the rotating shaft in the vertical direction, and an elastic member is arranged between the lowermost transmission gear and the corresponding gear two. When the driving component two drives the transmission gear to move downward, the elastic member is compressed. When the driving component two cancels the driving of the transmission gear, the elastic force of the elastic member makes the transmission gear move upward.

[0019] Preferably, the driving component two includes a driving rod and an installation box. The installation box is fixedly installed on the top of the mixing cylinder. The rotating shaft and the transmission gears are located inside the installation box. The driving rod penetrates the installation box and abuts against the uppermost transmission gear. A driving sleeve sleeved on the outer periphery of the driving rod is fixedly connected to the installation box. A threaded groove is formed in the driving sleeve. A plurality of protrusions adapted to the threaded groove are uniformly arranged on the driving rod at intervals along its axial direction. When the driving rod is rotated, the protrusions move along the threaded groove to drive the driving rod to move up and down.

[0020] Through the cooperation of the elastic member and the driving rod, the relative positions of the multiple transmission gears on the rotating shaft in the vertical direction are kept unchanged. Thus, when replacing the transmission gear meshing with the gear ring, every time a transmission gear is adjusted, the distance that the driving rod moves up or down is fixed. This not only facilitates the staff to judge the number of replaced transmission gears based on the moving distance of the driving rod, so as to finally adjust to the required transmission gear, but also improves the efficiency of replacing the transmission gear.

[0021] Preferably, a screwing handle is fixedly connected to the top of the driving rod. When the driving rod rotates one week, one transmission gear is replaced.

[0022] Preferably, the stirring assembly includes a first motor, a main shaft, plow knives, a second motor and flying knives. The first motor is fixedly installed on the stirring cylinder. The main shaft is fixedly connected to the output end of the first motor. The plow knives are fixedly installed on the main shaft. The second motors are arranged on the stirring cylinder at equal intervals along the axial direction of the stirring cylinder. The flying knives are fixedly connected to the output ends of the second motors.

[0023] The beneficial effects of the present invention are as follows: The present invention drives the material distribution cylinder to rotate through the driving assembly, so that when the feed bin passes through the second blanking port, the fertilizer raw materials are released. Since the volumes of the feed bins are the same, by controlling the rotation angle of the material distribution cylinder, the corresponding number of feed bins pass through the blanking port in sequence, and the quantitative release of the fertilizer raw materials can be realized; Moreover, the present invention realizes the quantitative release of different fertilizer raw materials by driving the material distribution cylinders in multiple hoppers to rotate by different angles, and realizes the proportioning of different fertilizer raw materials; While the present invention releases the fertilizer raw materials, it proportions the fertilizer raw materials, which not only improves the efficiency of releasing the fertilizer raw materials, but also omits many components such as weighing equipment, making the structure of the present invention compact, occupying a small area, and reducing the production cost; The present invention shears and crushes the fertilizer raw materials in the hopper through the first crushing rod and the second crushing rod, reduces the caking of the fertilizer in the hopper, enables the fertilizer to smoothly enter the feed bin, and is fully mixed after entering the stirring cylinder.

Detailed implementation manners

[0034] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention and should not be construed as a limitation to the present invention.

[0035] As Figures 1 to 9 shown, a fertilizer stirring device of the present invention includes a horizontal stirring cylinder 1 and a stirring assembly arranged in the stirring cylinder 1. The stirring assembly includes a first motor 2, a main shaft 21, a ploughshare 22, a second motor 23 and a flying knife 24. The first motor 2 is fixedly installed on the stirring cylinder 1. The main shaft 21 is fixedly connected to the output end of the first motor 2. The ploughshare 22 is fixedly installed on the main shaft 21. The first motor 2 drives the main shaft 21 to drive the ploughshare 22 to rotate to mix the fertilizer raw materials entering the stirring cylinder 1. The second motors 23 are arranged on the stirring cylinder 1 at equal intervals along the axial direction of the stirring cylinder 1. The flying knives 24 are fixedly connected to the output ends of the corresponding second motors 23. The second motors 23 drive the flying knives 24 to rotate to crush and mix the fertilizer raw materials in the stirring cylinder 1.

[0036] AsFigure 4 and Figure 6 As shown in Figure 6 , two hoppers 3 are fixedly installed at the top of the mixing drum 1. A first baffle 31 and a second baffle 32 are arranged up and down in the hopper 3, and the first baffle 31 and the second baffle 32 are respectively fixedly connected to the hopper 3. A distributing cylinder 4 is rotatably connected between the first baffle 31 and the second baffle 32, and eight bins 41 are equally divided in the distributing cylinder 4. As Figures 6 to 8 shown in Figures 6 to 8 , a first material dropping port 311 is formed on the first baffle 31, and a second material dropping port 321 which is vertically staggered with the first material dropping port 311 is formed on the second baffle 32. The first material dropping port 311 and the second material dropping port 321 correspond to the shape of the bin 41.

[0037] A driving assembly for driving the distributing cylinder 4 to rotate is arranged on the mixing drum 1. When the bin 41 is opposite to the first material dropping port 311, the fertilizer raw material in the hopper 3 enters the bin 41. When the bin 41 is opposite to the second material dropping port 321, the fertilizer raw material in the bin 41 enters the mixing drum 1. Since the volumes of the bins 41 are the same, by driving the distributing cylinder 4 to rotate by a required angle, the corresponding number of bins 41 can pass through the second material dropping port 321 in sequence, realizing the quantitative feeding of the fertilizer raw material; by driving the distributing cylinders 4 in the two hoppers 3 to rotate by different angles, the distributing cylinder 4 realizes the proportioning of the two fertilizer raw materials.

[0038] As Figure 8 and Figure 9 shown in Figure 8 and Figure 9 , a first crushing rod 33 and a second crushing rod 43 are arranged up and down in the hopper 3. The first crushing rod 33 and the second crushing rod 43 extend in the horizontal direction, and the first crushing rod 33 is fixedly connected to the hopper 3. The distributing cylinder 4 is fixedly connected with a coaxial installation shaft 42, and the installation shaft 42 penetrates upward through the first baffle 31, and the second crushing rod 43 is fixedly connected to the installation shaft 42. When the distributing cylinder 4 drives the second crushing rod 43 to pass under the first crushing rod 33, the first crushing rod 33 and the second crushing rod 43 shear and crush the fertilizer raw material in the hopper 3, reducing the caking of the fertilizer in the hopper 3, enabling the fertilizer to smoothly enter the bin 41 and being fully mixed after entering the mixing drum 1.

[0039] As Figure 5 , Figure 8 and Figure 9 shown in Figure 5 , Figure 8 and Figure 9 , the first crushing rod 33 is fixedly connected with an installation ring 5. The installation ring 5 is sleeved on the outer periphery of the installation shaft 42 and is coaxially arranged with the distributing cylinder 4. Three third crushing rods 51 are evenly arranged at intervals on the installation ring 5, and the lower ends of the third crushing rods 51 are rotatably connected to the installation ring 5. A driving member for driving the plurality of third crushing rods 51 to rotate synchronously upward or downward is arranged in the hopper 3.

[0040] The driving member includes an installation sleeve 52 and a connecting rod 53. The installation sleeve 52 is sleeved on the outer periphery of the installation shaft 42, and the connecting rod 53 is hinged between the installation sleeve 52 and the corresponding crushing rod III 51. A guiding groove 421 is formed on the outer periphery of the installation shaft 42, and a guiding block (not shown in the figure) extending into the guiding groove 421 is fixedly connected inside the installation sleeve 52. When the installation shaft 42 rotates, the guiding groove 421 pushes the guiding block to drive the installation sleeve 52 to move up and down, and the installation sleeve 52 drives the crushing rod III 51 to rotate up and down through the connecting rod 53.

[0041] When the three crushing rods III 51 rotate upward simultaneously, the space between the three crushing rods III 51 and the angle between the crushing rod III 51 and the installation shaft 42 will gradually become smaller, which can break the larger-volume fertilizer lumps existing in the hopper 3. Moreover, during the repeated up-and-down swinging process of the crushing rod III 51, the crushing rod III 51 stirs the fertilizer raw materials in the hopper 3, which helps the fertilizer raw materials to quickly enter the bin 41 of the material distribution cylinder 4.

[0042] As Figure 8 and Figure 9 As shown, the driving assembly includes a driving component I, a driving component II corresponding to each material distribution cylinder 4, a gear set, and a gear ring 40. The gear ring 40 is fixedly connected to the outer periphery of the material distribution cylinder 4. The gear set includes a rotating shaft 6 and four transmission gears 61 arranged on the rotating shaft 6. The rotating shaft 6 is rotatably connected to the mixing cylinder 1. The number of teeth of the four transmission gears 61 gradually decreases from bottom to top, and the tooth parts of the multiple transmission gears 61 are vertically corresponding. Except for the lowermost transmission gear 61, the other transmission gears 61 are incomplete gears.

[0043] The driving component I drives the rotating shaft 6 to drive the transmission gears 61 to rotate. The transmission gears 61 drive the gear ring 40 meshing with them to rotate, and the gear ring 40 drives the corresponding material distribution cylinder 4 to rotate. The driving component II drives the transmission gears 61 to move up and down to replace the transmission gears 61 meshing with the gear ring 40, so as to change the rotation angle of the gear ring 40 and the material distribution cylinder 4, achieving the effect of changing the ratio of fertilizer raw materials. For the four transmission gears 61 on the rotating shaft 6, every time one transmission gear 61 is replaced from bottom to top to mesh with the gear ring 40, the angle that the rotating shaft 6 can drive the material distribution cylinder 4 to rotate when the rotating shaft 6 rotates one week is reduced by 90°, that is, the fertilizer discharge amount of two bins 41 is reduced. The staff can replace the transmission gears 61 corresponding to the material distribution cylinder 4 according to the ratio of the fertilizer raw materials in the two hoppers 3.

[0044] The first driving component includes a driving motor 7, a first gear 71, and a second gear 72 corresponding to each material distribution cylinder 4. An installation box 11 is fixedly installed at the top of the mixing cylinder 1, and a rotating shaft 6 and a transmission gear 61 are located inside the installation box 11. The driving motor 7 is fixedly installed on the installation box 11 on the mixing cylinder 1. The first gear 71 is fixedly connected to the output end of the driving motor 7. The second gear 72 is fixedly connected to the corresponding rotating shaft 6. The first gear 71 meshes with the second gear 72. The driving motor 7 drives the first gear 71 to drive the second gear 72 to rotate. The second gear 72 drives the rotating shaft 6 and the transmission gear 61 to rotate. The transmission gear 61 drives the corresponding material distribution cylinder 4 to rotate.

[0045] The transmission gear 61 is slidably connected to the rotating shaft 6 in the vertical direction, and an elastic member, as an example, a spring 73, is provided between the lowermost transmission gear 61 and the corresponding second gear 72. When the second driving component drives the transmission gear 61 to move downward, the elastic member is compressed. When the second driving component cancels the driving of the transmission gear 61, the elastic force of the elastic member causes the transmission gear 61 to move upward.

[0046] The second driving component includes a driving rod 8. The driving rod 8 penetrates through the installation box 11 and abuts against the uppermost transmission gear 61. A driving sleeve 12 sleeved on the outer periphery of the driving rod 8 is fixedly connected to the installation box 11. A threaded groove (not shown in the figure) is provided in the driving sleeve 12. A plurality of protrusions 81 adapted to the threaded groove are uniformly arranged at intervals along the axial direction of the driving rod 8. When the driving rod 8 is rotated, the protrusions 81 move along the threaded groove to drive the driving rod 8 to move up and down. The elastic member cooperates with the driving rod 8 to keep the relative positional relationship of the four transmission gears 61 on the rotating shaft 6 unchanged in the vertical direction. Thus, when replacing the transmission gear 61 meshing with the gear ring 40, the distance that the driving rod 8 moves up or down is fixed for each adjustment of a transmission gear 61, which is convenient for the staff to judge the number of replaced transmission gears 61 based on the moving distance of the driving rod 8, so as to finally adjust to the required transmission gear 61.

[0047] A screwing handle 82 is fixedly connected to the top of the driving rod 8. Marks (not shown in the figure) are respectively provided on the rod body of the driving rod 8 and the top of the driving sleeve 12. When the driving rod 8 rotates one week, the marks on the rod body and the marks on the driving sleeve 12 are aligned. For each rotation of the driving rod 8, one transmission gear 61 is replaced, which is convenient for the staff to observe and record to ensure that the ratio of the fertilizer raw materials in the material distribution cylinders 4 of the two hoppers 3 meets the requirements.

[0048] It can be understood that although only two hoppers 3 are provided at the top of the mixing cylinder 1 in the above embodiments, this is not a limitation on the number of hoppers 3. In other embodiments, three or four hoppers 3 can also be provided at the top of the mixing cylinder 1 according to the types of fertilizer raw materials.

[0049] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
