Description

Technical Field

[0001] This invention relates to the field of fertilizer production technology, specifically to a mixing and stirring device that can prevent fertilizer from clumping. Background Technology

[0002] Fertilizers are substances that provide one or more essential nutrients for plants, improve soil properties, and enhance soil fertility. They are one of the material bases of agricultural production and mainly include ammonium phosphate fertilizers, water-soluble fertilizers containing macronutrients, fertilizers containing micronutrients, bio-fertilizers, and organic fertilizers.

[0003] Some organic fertilizers are mixed with water and other trace elements before use, which makes fertilization easier and can improve the fertilizer's fertility.

[0004] Traditional mixing methods rely on manual stirring, which is not only time-consuming and labor-intensive but also prone to uneven mixing, leading to fertilizer clumping and incomplete dispersion, thus affecting the final fertilization and fertilizer fertility. Currently, simple mechanical mixing is commonly achieved using stirring rods, but these devices generally have a single mixing method and the mixing tank itself cannot move, resulting in insufficient mixing and fertilizer clumping. In view of this, we propose a mixing device that can prevent fertilizer clumping. Summary of the Invention

The top of the circular plate has four through arc-shaped grooves, which are evenly spaced in a circular array on the top of the circular plate. The annular cross-section formed by the arc-shaped grooves is located directly below the discharge port at the bottom of the hopper, so that the fertilizer can fall smoothly into the mixing tank.

[0015] Compared with the prior art, the present invention provides a mixing and stirring device that can prevent fertilizer from clumping, and has the following beneficial effects: 1. This mixing and stirring device, which can prevent fertilizer from clumping, is equipped with a moving mechanism to better mix fertilizer and prevent clumping. When the servo motor is started, it works with the rotating shaft, L-shaped rod, hinge rod, and ball joint to make the push rod reciprocate left and right inside the fixed rod. Furthermore, with the help of the long strip block, the slider reciprocates left and right inside the slide rail.

This allows the fertilizer inside the tank to shake better and prevent clumping.

[0016] 2. This mixing and stirring device, which can prevent fertilizer from clumping, is equipped with a rotating component to achieve better mixing effect. When the rotating shaft rotates, it works with the driving pulley, vertical transmission belt, and driven pulley to make the cylinder rotate. This, in turn, works with the right pulley, horizontal transmission belt, and left pulley to make the rotating rod rotate. This, in turn, works with the driving bevel gear, rectangular plate, and driven bevel gear to make the central shaft rotate, thereby making the stirring rod rotate to stir the fertilizer mixture.

[0017] 3. This mixing and stirring device can prevent fertilizer from clumping. In order to prevent the fertilizer mixture from sticking to the inner wall of the mixing tank, a cleaning mechanism is set up. When the central shaft rotates, in conjunction with the telescopic rod, the scraper continuously scrapes the inner wall of the mixing tank. At the same time, the elasticity of the spring makes the scraper fit tightly against the inner wall of the mixing tank, achieving a better scraping effect.

[0018] 4. This mixing and stirring device, which can prevent fertilizer from clumping, reduces the speed at which fertilizer enters the mixing tank and prevents too much fertilizer from entering at once, thus affecting the mixing effect. It is equipped with an auxiliary component. When the central shaft rotates, it drives the circular plate to rotate, so that the arc-shaped groove intermittently passes through the discharge port at the bottom of the hopper. That is, fertilizer will only fall into the mixing tank when it passes through the discharge port. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-7 The present invention provides a technical solution: a mixing and stirring device that can prevent fertilizer from clumping, including a frame 1, a through rectangular groove 2 on the top right end of the frame 1, a servo motor 3 fixedly installed on the top inner side of the right end of the frame 1, the bottom of an L-shaped bracket 4 fixedly connected to the top of the frame 1, and a moving mechanism 5 provided on the top of the frame 1.

[0023] In one embodiment of the present invention, the moving mechanism 5 includes a rotating shaft 51. The output end of a servo motor 3 is fixedly connected to one end of the rotating shaft 51. When the servo motor 3 is started, it drives the rotating shaft 51 to rotate. The other end of the rotating shaft 51 is fixedly connected to one end of an L-shaped rod 52, thereby driving the L-shaped rod 52 to rotate. The end of the L-shaped rod 52 away from the rotating shaft 51 is hinged to one end of a hinge rod 53, thereby driving one end of the hinge rod 53 to rotate. The end of the hinge rod 53 away from the L-shaped rod 52 is hinged to the right movable end of a ball joint 54. The top of the left end of the frame 1 is fixedly connected to the bottom of a slide rail 55. The slide rail 55 is slidably connected to the outer wall of a slider 56, thereby cooperating with... The ball joint 54 drives the push rod 58 to reciprocate left and right inside the fixed rod 59. The right outer wall of the slider 56 is fixedly connected to the left outer wall of the long strip block 57. The central axis of the right outer wall of the long strip block 57 is fixedly connected to the left outer wall of the push rod 58. There are two L-shaped rods 52, which are symmetrically arranged on both sides of the rectangular groove 2 with the horizontal center line in the left and right directions as the axis of symmetry. The top of the frame 1 is fixedly connected to the bottom of the fixed rod 59. The arc-shaped inner wall of the top of the fixed rod 59 is slidably connected to the arc-shaped outer wall of the push rod 58. The right outer wall of the push rod 58 is fixedly connected to the left fixed end of the ball joint 54. The hinge rod 53, ball joint 54, push rod 58, and fixed rod 5 are also connected. 9 and rectangular groove 2 are located in the same vertical plane. The hinge rod 53 is located directly above the rectangular groove 2 so that the movement of the hinge rod 53 does not interfere with the movement of the frame 1. The side wall of the slider 56 is engaged with the outer wall of the bottom end of the side rod 510. Furthermore, in conjunction with the long strip block 57, the slider 56 can reciprocate left and right inside the slide rail 55. The outer wall of the other end of the top of the side rod 510 is fixedly connected to the arc-shaped outer wall of the arc rod 511. There are two sets of slide rail 55, slider 56, side rod 510 and arc rod 511, and they are mirrored with the horizontal center line of the rectangular groove 2 as the mirror axis. The outer walls of the right sides of the two sliders 56 are respectively fixedly connected to the long strip block. The two sliders 56 are attached to the bottom surface of the inner and outer sides of the mixing tank 6, respectively. The inner walls of the two arc-shaped rods 511 are attached to the inner and outer arc-shaped outer walls of the mixing tank 6. In addition, the side rods 510 and the arc-shaped rods 511 are used to clamp and fix the mixing tank 6, so that the mixing tank 6 can move back and forth, which can better shake the fertilizer mixture inside the tank and effectively prevent clumping. The top of the mixing tank 6 is fitted with a lid 7. An L-shaped glass tube 8 is connected through the arc-shaped outer wall of the left side of the mixing tank 6, so that the liquid level inside the mixing tank 6 can be easily seen from the outside by utilizing the principle of equal liquid level in communicating vessels.

[0024] In one embodiment of the present invention, a rotating assembly 9 is provided on the top of the frame 1. The arc-shaped outer wall of the rotating shaft 51 is fixedly connected to the arc-shaped inner wall of the driving pulley 91. The driving pulley 91 is located inside the L-shaped rod 52. When the rotating shaft 51 rotates, it will drive the driving pulley 91 to rotate. The arc-shaped outer wall of the driving pulley 91 is connected to the inside of one end of the bottom of the vertical transmission belt 92. A cylinder 93 is rotatably installed between the top right sides of the two L-shaped brackets 4, thereby driving the vertical transmission belt 92. The arc-shaped outer wall of the inner side of the cylinder 93 is fixedly connected to the arc-shaped inner wall of the driven pulley 94. The arc-shaped outer wall of the driven pulley 94 is connected to the inside of the other end of the top of the vertical transmission belt 92, thereby driving the driven pulley 94 to rotate, thus making the cylinder... The column 93 rotates between two L-shaped supports 4. The arc-shaped outer wall of the column 93 is fixedly connected to the arc-shaped inner wall of the right pulley 95. The right pulley 95 is located inside the driven pulley 94, thus driving the right pulley 95 to rotate. The arc-shaped outer wall of the right pulley 95 is connected to the inside of the right side of the horizontal transmission belt 96. A rotating rod 97 is rotatably installed inside the left end of an L-shaped support 4 located inside the horizontal transmission belt 96. The arc-shaped outer wall of the rotating rod 97 is fixedly connected to the arc-shaped inner wall of the left pulley 98. The arc-shaped outer wall of the left pulley 98 is connected to the inside of the left side of the horizontal transmission belt 96, thus driving the left pulley 98 to rotate through the transmission of the horizontal transmission belt 96. This causes the rotating rod 97 to rotate inside the L-shaped support 4. The arc-shaped outer wall of the rotating rod 97 is fixedly connected to... Inside the driving bevel gear 99, two rectangular plates 910 are fixedly installed between the left ends of the two L-shaped brackets 4. A central shaft 911 is slidably sleeved inside the center of the rectangular plate 910. The arc-shaped outer wall of the top of the central shaft 911 is engaged with the inside of the driven bevel gear 913 via a key 912. This arrangement allows the central shaft 911 to be easily removed downwards from the driven bevel gear 913. The bottom of the driven bevel gear 913 is attached to the top of the rectangular plate 910 located below. The driving bevel gear 99 meshes with the driven bevel gear 913. A nut 914 is threadedly connected to the top of the central shaft 911. The bottom of the nut 914 is attached to the top of the rectangular plate 910 located above. At the top, loosening the nut 914 allows the central shaft 911 to be easily removed downwards from the rectangular plate 910. The top of the lid 7 has a through slot 915, and the central shaft 911 is located inside the through slot 915. The through slot 915 ensures that when the mixing tank 6 moves back and forth with the lid 7, there will be no movement interference with the central shaft 911, thereby driving the driven bevel gear 913 to rotate. This, in turn, engages with the key 912 to allow the central shaft 911 to rotate inside the two rectangular plates 910. The arc-shaped outer wall of the central shaft 911 is fixedly equipped with a stirring rod 916. There are three sets of stirring rods 916, which allow the stirring rods 916 to rotate and stir the fertilizer mixture, thereby achieving a better stirring effect.

[0025] In one embodiment of the present invention, a cleaning mechanism 10 is provided inside the mixing tank 6. A telescopic rod 1001 is fixedly connected to one side wall of its arc-shaped outer wall. There are two sets of four telescopic rods 1001, mirrored about the vertical centerline of the central axis 911. Two ends of each set of two telescopic rods 1001, away from the central axis 911, are fixedly connected to the upper and lower side walls of a scraper 1002. The side wall of the scraper 1002 away from the telescopic rods 1001 fits against the arc-shaped inner wall of the mixing tank 6. A spring is sleeved on the outer side of the telescopic rod 1001. Spring 1003, one end of spring 1003 is attached to the outer wall of central shaft 911, and the other end of spring 1003 is attached to the outer wall of scraper 1002, so that the elastic force of spring 1003 can make scraper 1002 fit more tightly to the inner wall of mixing tank 6. When central shaft 911 rotates, in conjunction with telescopic rod 1001, scraper 1002 scrapes continuously on the inner wall of mixing tank 6. At the same time, the elastic force of spring 1003 makes scraper 1002 fit tightly to the inner wall of mixing tank 6, achieving a better scraping effect, thereby preventing fertilizer mixture from sticking to the inner wall of mixing tank 6.

[0026] In one embodiment of the present invention, an auxiliary component 11 is provided inside the mixing tank 6, and a hopper 1101 is snapped into the top of the tank cover 7. The arc-shaped outer wall of the central shaft 911 is fixedly connected to the central arc-shaped inner wall of the circular plate 1102. The bottom of the circular plate 1102 is located above the top of the scraper 1002. The discharge port at the bottom end of the hopper 1101 is attached to the top of the circular plate 1102. The top of the circular plate 1102 has four through arc-shaped grooves 1103, which are evenly spaced in a circular array on the circular plate 1102. At the top of 102, the annular cross-section formed by the arc-shaped groove 1103 is located directly below the discharge port at the bottom of the hopper 1101, so that the fertilizer can fall smoothly into the mixing tank 6. When the central shaft 911 rotates, it will drive the circular plate 1102 to rotate, so that the arc-shaped groove 1103 intermittently passes through the discharge port at the bottom of the hopper 1101. That is, only when it passes through will the fertilizer fall into the mixing tank 6, thereby reducing the speed at which the fertilizer enters the mixing tank 6 and preventing too much fertilizer from entering at once, which would affect the mixing effect.

[0027] Working principle: When the servo motor 3 is started, it drives the rotating shaft 51 to rotate, which in turn drives the L-shaped rod 52 to rotate, which in turn drives one end of the hinge rod 53 to rotate. This, in conjunction with the ball joint 54, drives the push rod 58 to reciprocate left and right inside the fixed rod 59. Furthermore, in conjunction with the long strip block 57, the slider 56 reciprocates left and right inside the slide rail 55. In addition, the side rod 510 and the arc rod 511 clamp and fix the mixing tank 6, causing the mixing tank 6 to reciprocate left and right. This allows for better shaking of the fertilizer mixture inside the tank, effectively preventing clumping. When the rotating shaft 51 rotates, it drives the driving pulley 91 to rotate, which, through the vertical transmission belt 92, drives the driven pulley 94 to rotate. This causes the cylinder 93 to rotate between the two L-shaped supports 4, which in turn drives the right pulley 95 to rotate. This, through the horizontal transmission belt 96, drives the left pulley 98 to rotate, causing the rotating rod 97 to rotate within the L-shaped support. 4. The internal rotation drives the active bevel gear 99 to rotate, which in turn drives the driven bevel gear 913 to rotate. This, in conjunction with the key 912, causes the central shaft 911 to rotate inside the two rectangular plates 910, thereby causing the stirring rod 916 to rotate and stir the fertilizer mixture, achieving a better stirring effect. When the central shaft 911 rotates, it works with the telescopic rod 1001 to cause the scraper 1002 to continuously scrape against the inner wall of the mixing tank 6. At the same time, the elastic force of the spring 1003 makes the scraper 1002 fit tightly against the inner wall of the mixing tank 6, achieving a better scraping effect. To prevent the fertilizer mixture from sticking to the inner wall of the mixing tank 6, when the central shaft 911 rotates, it drives the circular plate 1102 to rotate, so that the arc-shaped groove 1103 intermittently passes through the bottom discharge port of the hopper 1101. That is, only when it passes through will the fertilizer fall into the mixing tank 6, thereby reducing the speed at which the fertilizer enters the mixing tank 6 and preventing too much fertilizer from entering at once, which would affect the mixing effect.

[0028] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
