Description

Technical Field

[0001] The invention relates to the technical field of blended fertilizer production, in particular to a mixing device for blended fertilizer production. Background Art

[0002] Fertilizer is an indispensable element in modern agricultural production. Reasonable fertilizer ratio and uniform blending play an important role in improving crop yield and quality. Blended fertilizer, also known as formula fertilizer or BB fertilizer, is made of two or more single fertilizers or compound fertilizers with similar particle sizes as raw materials. It is a mixture of various raw materials in a certain proportion through simple mechanical blending. The purpose of blended fertilizer is to provide multiple nutrients in one fertilization process to meet the needs of crops. By selecting a suitable fertilizer combination, the proportion of different nutrients can be adjusted to meet the nutrient needs of different crops at different growth stages. The specific method of blending fertilizers can be adjusted according to factors such as crop type, soil conditions and nutrient requirements. Generally speaking, different types of fertilizers can be mixed in a certain proportion, fully stirred, and then applied according to the appropriate amount of fertilizer.

[0003] The existing Chinese patent with publication number CN117717949A includes a support base, a plurality of first support frames are fixedly connected to the periphery of the top of the support base, and a second support frame is fixedly connected to the top of each of the plurality of first support frames; a spiral mixing mechanism is fixedly connected between the plurality of second support frames, and a flexible mixing mechanism is fixedly connected between the plurality of first support frames; a rotary drive mechanism is installed on the top of the support base, and a top-loading mechanism corresponding to the flexible mixing mechanism is installed on the top of the rotary drive mechanism.

[0004] When the above device is in use, by designing a spiral mixing mechanism and a flexible mixing mechanism, it can not only complete the pre-mixing and full mixing of the blended fertilizers, but also effectively reduce the breakage rate of the blended fertilizers during the mixing process by adopting a flexible mixing structure. However, in actual use, when a large amount of fertilizers are piled up in the mixing hopper, the weight of the upper fertilizer will suppress the lower fertilizer, making it difficult for the lower fertilizer to be squeezed and turned over, resulting in uneven fertilizer mixing. Therefore, it is difficult to mix different fertilizers in a quantitative manner in proportion. Summary of the invention

[0005] The object of the present invention is to provide a mixing device for producing blended fertilizers, which has the advantage of mixing different fertilizers in a quantitative manner according to a proportion, and solves the problems in the background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a mixing device for producing blended fertilizers, comprising a base supported by an external bracket and placed on the ground, a mixing box being penetrated and fixedly connected to the base, a plurality of equidistantly arranged feeding pipes being penetrated and fixedly connected to symmetrical positions on both sides of the end of the mixing box, each end of the feeding pipe being penetrated and fixedly connected to a storage tank for storing different fertilizers respectively, a fixed seat being fixedly connected to one side of each feeding pipe close to the bottom end, a connecting seat being rotatably connected to each fixing seat via a pin shaft, a sealing plate for sealing the bottom end of the feeding pipe being fixedly connected to the end of each connecting seat away from the fixed seat, and a feeding mechanism for quantitatively feeding different fertilizers into the storage tank is provided on the mixing box.

[0008] Preferably, the end of the mixing box is penetrated and connected to an elliptical plate driven to rotate by a power mechanism in a fixed axis rotation, and an elliptical groove is provided at the bottom of the elliptical plate. The inner walls of the elliptical grooves at symmetrical positions on both sides of the elliptical plate are movably connected to pull rods for pulling the material receiving frame to perform horizontal reciprocating shaking, and the ends of the pull rods on both sides away from the elliptical plate are fixedly connected to the support plate on the adjacent side.

[0009] Preferably, fixed blocks are fixedly connected to the opposite sides of the two track plates on each side, a U-shaped rod is penetrated and connected to the two fixed blocks on each side for lifting and lowering movement, a knocking block is fixedly connected to the U-shaped rod for knocking on the bottom of the docking material frame, first protrusions are fixedly connected to both ends of the U-shaped rod on each side, a spring is fixedly connected to the opposite surface of each first protrusion and the fixed block for guiding the U-shaped rod to reset, and second protrusions that push the knocking block to knock on the docking material frame are fixedly connected to the symmetrical positions on both sides of each material connection frame.

[0010] Preferably, the mixing box is provided with a mixing mechanism for pre-mixing different fertilizers, the mixing mechanism includes a mixing hopper fixedly connected to one end of the inner wall of the mixing box close to the elliptical plate through an external bracket, a mixing plate for stirring and mixing the fertilizers inside the mixing hopper is coaxially fixedly connected to the bottom of the elliptical plate, and the mixing plate is in contact with the inner wall of the mixing hopper and is movably connected.

[0011] Preferably, a fixed sleeve is fixedly connected to the inner wall of the mixing box near the bottom end, and the fixed sleeve is provided with a dispersing mechanism for evenly dispersing the fertilizer on the inner wall of the mixing box. The dispersing mechanism includes a rotating tube that penetrates the inner wall of the fixed sleeve and is rotatably connected thereto, a conical block for evenly dispersing the fertilizer is fixedly connected to the outer contour of the end of the mixing box, and a gear is fixedly connected to the outer contour of the rotating tube near the bottom end of the conical block, and tooth plates are meshingly connected to the gear at symmetrical positions on both sides, and the ends of the two tooth plates are respectively fixedly connected to the material receiving frame on the adjacent side.

[0012] Preferably, a collecting hopper for centrally mixing the fertilizers inside the mixing box is fixedly connected to the bottom end of the mixing box, and a sealing plug for sealing is fixedly connected to the inner wall of the bottom end of the collecting hopper.

[0013] Preferably, feeding holes for fertilizer to enter the rotating tube are provided at symmetrical positions on both sides of the bottom end of the rotating tube, and the inner wall of the rotating tube is rotatably connected to a spiral blade for secondary dispersion of the fertilizer inside the collecting hopper, and the spiral blade is coaxially fixed to the elliptical plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting up the track plate, material receiving frame, sealing plate and other structures in the mixing box, it is ensured that the fertilizers in different storage tanks enter the mixing box in a quantitative manner as needed. The design of the track plate and the material receiving frame enables the sealing plate to be opened and closed during the feeding process, so as to achieve accurate quantitative feeding of fertilizers. This structure significantly improves the accuracy of fertilizer ratio.

[0015] 2. By setting up an elliptical plate and a receiving frame assembly, combined with the reciprocating shaking of the pull rod, different fertilizers can be fully shaken in the receiving frame while being put in, thereby achieving preliminary mixing. At the same time, the shaking of the receiving frame can put the internal fertilizers into the mixing hopper in small amounts at a uniform speed, so that the mixing plate can fully stir the different fertilizers in the mixing hopper, thereby improving the overall uniformity and mixing efficiency of the fertilizers.

[0016] 3. The dispersion mechanism adopts a conical block and a gear tooth plate connection. The conical block is rotated back and forth in the mixing box through gear transmission, which can evenly disperse the fertilizer on the inner wall of the mixing box. The design of the conical block effectively solves the problem of fertilizer stratification caused by gravity, so that different fertilizer components can be evenly distributed in the mixing box. This efficient dispersion method improves the mixing effect of the fertilizer, and there will be no situation where the local fertilizer concentration is too high or insufficient, thereby enhancing the uniformity and effect of fertilizer mixing.

[0017] Fourth, the spiral blades at the bottom of the mixing box achieve a secondary dispersion effect on the fertilizer. During the rotation process, the spiral blades evenly transport the fertilizer from the bottom of the collecting hopper to the end of the conical block, achieving a secondary dispersion of the fertilizer. After the initial mixing and dispersion, the secondary dispersion process further refines the distribution of the fertilizer, avoids local accumulation of fertilizer, and improves the mixing quality and uniformity of the fertilizer.

[0018] The coordinated use of the above-mentioned structure solves the problem that, in actual use of the existing device, when a large amount of fertilizers are piled up in the mixing hopper, the weight of the upper layer of fertilizers will suppress the lower layer of fertilizers, making it difficult for the lower layer of fertilizers to be squeezed and turned, resulting in uneven fertilizer mixing, and therefore it is difficult to mix different fertilizers in a quantitative manner in proportion.

[0024] When in use, by setting up the base 1, the base 1 is first placed on the ground through the support of an external bracket to improve the stability of the mixing device. Through the mixing box 2 set on the base 1, the mixing box 2 is fixedly supported on the base 1, and through the feeding pipe 3 set on the mixing box 2 and the storage tank 4 set on the feeding pipe 3, the feeding pipe 3 connects the storage tank 4 with the mixing box 2, and the different fertilizers that need to be mixed are stored in the storage tank 4 according to the proportion, so that the subsequent feeding pipe 3 can quantitatively feed the different fertilizers in the storage tank 4 into the mixing box 2.

[0025] Through the fixed seat 5 arranged on the feed pipe 3, and the connecting seat 6 and the sealing plate 7 arranged on the fixed seat 5, the connecting seat 6 can drive the sealing plate 7 to reciprocate and rotate on the fixed seat 5, and through the feeding mechanism arranged on the mixing box 2, the feeding mechanism can drive the sealing plate 7 to seal or release the feed pipe 3, so as to realize the quantitative feeding of the fertilizer inside the storage tank 4.

[0026] Embodiment 2

[0027] On the basis of the first embodiment, further: The feeding mechanism includes two symmetrically placed track plates 8 fixedly connected at symmetrical positions on both sides of the inner wall of the mixing box 2 near the top, and a material receiving frame 9 is movably connected in the slide groove on the opposite sides of the two track plates 8 on each side, and a support plate 10 for supporting the sealing plate 7 is fixedly connected at the position corresponding to the feeding pipe 3 on each side of the material receiving frame 9.

[0028] The end of the mixing box 2 is penetrated and connected to an elliptical plate 11 driven to rotate by a power mechanism in a fixed axis, and an elliptical groove 111 is opened at the bottom of the elliptical plate 11. The inner walls of the elliptical grooves 111 at symmetrical positions on both sides of the elliptical plate 11 are movably connected with pull rods 12 for pulling the material receiving frame 9 to perform horizontal reciprocating shaking, and the ends of the pull rods 12 on both sides away from the elliptical plate 11 are fixedly connected to the support plate 10 on the adjacent side.

[0029] When in use, the track plate 8 provided on the mixing box 2 is used to fix and support the track plate 8 on the mixing box 2, and the material receiving frame 9 provided on the track plate 8 is used, and the track plate 8 provides limited support for the moving direction of the material receiving frame 9, so that the material receiving frame 9 is horizontally movable and connected to the inner wall of the track plate 8, and the support plate 10 provided on the material receiving frame 9 is used, and the support plate 10 is in conflict with the sealing plate 7 on the top, so that the sealing plate 7 seals the bottom end of the feed pipe 3 under the action of the support plate 10.

[0030] Through the elliptical plate 11 arranged on the mixing box 2, and the elliptical plate 11 is driven to rotate by a motor, so that the elliptical plate 11 can perform fixed-axis rotation on the mixing box 2 under the drive of the motor, and through the elliptical groove 111 opened on the elliptical plate 11 and the pull rod 12 arranged on the elliptical groove 111, the two pull rods 12 are respectively fixed on the support plate 10 on the adjacent side, and along with the fixed-axis rotation of the elliptical plate 11, the pull rod 12 can pull the material receiving frames 9 on both sides to reciprocate toward and away from each other under the action of the elliptical groove 111.

[0031] like Figure 2 , Figure 3 , Figure 4 and Figure 6As shown, when the pull rod 12 pulls the receiving frames 9 on both sides to move horizontally in opposite directions, the support plate 10 is out of contact with the sealing plate 7, and the sealing plate 7 can be rotated in the direction away from the feeding pipe 3 under the action of the gravity of the fertilizer inside the feeding pipe 3, and the sealing plate 7 releases the seal of the feeding pipe 3, so that the fertilizer inside the storage tank 4 falls through the feeding pipe 3 to the inner wall of the receiving frame 9 under the action of weight. When the pull rod 12 pushes the receiving frames 9 on both sides to reset in opposite directions, the support plate 10 can push the sealing plate 7 to rotate and seal with the bottom end of the feeding pipe 3, so that the storage tank 4 stops feeding the fertilizer, thereby realizing the quantitative feeding of different fertilizers inside the storage tank 4. As the receiving frame 9 shakes back and forth in opposite directions, the receiving frame 9 can feed the internal fertilizer at a uniform speed and in small amounts, so as to facilitate the subsequent uniform mixing of different fertilizers.

[0034] When in use, through the fixed block 13 set on the track plate 8 and the U-shaped rod 14 set on the fixed block 13, the fixed block 13 can fix and support the U-shaped rod 14 on the track plate 8, and at the same time, the U-shaped rod 14 is connected to the fixed block 13 for lifting and movement, and the knocking block 15 set on the U-shaped rod 14, the knocking block 15 is fixedly supported on the U-shaped rod 14, and the first protrusion 16 set on the U-shaped rod 14 and the spring 17 set on the first protrusion 16 can pull the knocking block 15 to fit with the bottom of the material receiving frame 9 under the elastic force of the spring 17.

[0035] like Figure 6 and Fig. 9As shown, by the second protrusion 18 set on the material receiving frame 9, the material receiving frame 9 performs horizontal reciprocating shaking, so that the material receiving frame 9 can drive the second protrusion 18 to synchronously perform horizontal reciprocating movement. When the second protrusion 18 moves and contacts with the first protrusion 16, the first protrusion 16 can push the U-shaped rod 14 and the knocking block 15 to move in the vertical direction away from the bottom of the material receiving frame 9 under the action of the second protrusion 18. At this time, the spring 17 is in a contracted state under the action of the first protrusion 16. When the second protrusion 18 is out of contact with the first protrusion 16, the first protrusion 16 can quickly pull the U-shaped rod 14 and the knocking block 15 in the vertical direction close to the bottom of the material receiving frame 9 under the elastic force of the spring 17, and then the knocking block 15 can knock on the bottom of the material receiving frame 9, and the material receiving frame 9 vibrates under the action of the knocking of the knocking block 15, so that the material receiving frame 9 can vibrate and shake off the fertilizers adhered and stacked inside, thereby improving the subsequent fertilizer mixing effect.

[0043] By means of the gear 25 arranged on the rotating tube 22 and the toothed plate 24 arranged on the gear 25, the toothed plate 24 and the teeth on the gear 25 are meshed with each other, and the toothed plate 24 is fixedly connected to the receiving frame 9, and as the receiving frame 9 reciprocates toward and away from each other, the gear 25 can drive the rotating tube 22 to reciprocate on the fixed sleeve 21 under the action of the toothed plate 24, and at the same time, the rotating tube 22 can drive the conical block 23 at the end to reciprocate synchronously, and the premixed fertilizer inside the mixing hopper 19 falls into the inside of the conical block 23, and then the reciprocating rotation of the conical block 23 can evenly disperse the fertilizer at the end inside the mixing box 2, and through the collecting hopper 26 arranged on the mixing box 2 and the sealing plug 27 arranged on the collecting hopper 26, the sealing plug 27 seals the collecting hopper 26, and at the same time, the collecting hopper 26 can evenly mix the fertilizer dispersed inside the mixing box 2 at the bottom, further improving the mixing effect of the blended fertilizer.

[0044] The sealing plug 27 is detachably connected to the collecting hopper 26 , and by removing the sealing plug 27 from the bottom end of the collecting hopper 26 , it is convenient for personnel to subsequently discharge the mixed fertilizers in the collecting hopper 26 in a centralized manner.

[0045] Embodiment 6

[0046] On the basis of the fifth embodiment, further: Feed holes 221 for fertilizer to enter the rotating tube 22 are provided at symmetrical positions on both sides of the bottom end of the rotating tube 22. The inner wall of the rotating tube 22 is rotatably connected to a spiral blade 28 for secondary dispersion of the fertilizer in the collecting hopper 26, and the spiral blade 28 is coaxially fixed to the elliptical plate 11.

[0047] When in use, the fertilizer inside the collecting hopper 26 can enter the inner wall of the rotating tube 22 through the feed hole 221 opened on the rotating tube 22, and through the spiral blade 28 set on the rotating tube 22, and the spiral blade 28 is coaxially fixedly connected to the elliptical plate 11, so that the elliptical plate 11 can drive the spiral blade 28 to rotate on the inner wall of the rotating tube 22, so that the spiral blade 28 can transport the mixed fertilizer at the bottom end of the collecting hopper 26 to the end of the conical block 23 for secondary dispersion, thereby further improving the uniformity and efficiency of fertilizer mixing.

[0048] As the rotating tube 22 reciprocates on the fixed sleeve 21, the fertilizer at the bottom of the collecting hopper 26 enters the inner wall of the rotating tube 22 through the feeding hole 221, thereby avoiding a large amount of fertilizer accumulating in the collecting hopper 26, causing blockage and making it difficult for the fertilizer to enter the interior of the rotating tube 22.

[0049] Furthermore, the existing device can mix different fertilizers in a quantitative manner according to a ratio during actual use, thereby improving the uniformity and efficiency of fertilizer mixing, and is easy to use, which is better than traditional products.
