Description

Technical Field

[0001] This invention belongs to the technical field of farmland remediation agent preparation device, specifically a farmland remediation agent preparation device and preparation method. Background Technology

[0002] The farmland remediation agent preparation device is a device for mixing farmland remediation agents. It mainly consists of a machine body, a stirring mechanism located inside the machine body, and a discharge valve installed at the bottom of the preparation machine. It is generally widely used in agricultural fields where factory wastewater is discharged.

[0003] Existing methods for preparing farmland remediation agents combine the aforementioned preparation apparatus with the following specific preparation method:

[0004] S1: First, the staff will pour the materials needed for the farmland restoration agent into the machine one by one;

[0005] S2: After the staff pours the materials required for the farmland remediation agent into the machine, the staff will start the motor inside the machine to drive the mixing components to mix the water and the materials required for the farmland remediation agent inside the machine.

[0006] S3: Finally, the mixing component is used to mix the farmland restoration agent inside the machine. Then, the staff opens the valve at the bottom of the machine to allow the farmland restoration agent prepared inside the machine to flow into the farmland for nutrient restoration.

[0007] Existing farmland remediation agent preparation devices and methods suffer from drawbacks during operation. The machine cannot simultaneously feed multiple materials required for farmland remediation agents; instead, workers must pour each material in one by one. This results in a large quantity of mixed materials being prepared before each pour, requiring significant physical exertion from the workers and leading to a prolonged overall feeding process and reduced work efficiency. Summary of the Invention

[0008] To address the problems mentioned in the background art, this invention provides a farmland remediation agent preparation device and method. This solves the problem that the preparation machine cannot simultaneously and gradually feed multiple materials required for the farmland remediation agent; instead, workers must pour the materials in one by one. This results in a large quantity of mixed materials being required before each pour, increasing the physical exertion required for workers during the individual pouring process, thus taking a long time and reducing overall work efficiency.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a farmland remediation agent preparation device, comprising a mixing mechanism, a feeding mechanism fixedly connected to the top of the mixing mechanism, a second housing fixedly connected to the top outer surface of the feeding mechanism via a support rod, a first housing fixedly added to one side of the feeding mechanism, a support member stabilizing the bottom of the mixing mechanism and the first housing, a discharge port fixedly connected to one side of the bottom of the mixing mechanism, a valve provided on one side of the discharge port, and branch pipes branched out at the bottom of the discharge port;

[0010] Inside the first housing, a rotating rod is connected to a support shaft on one side. A second gear and a third gear are connected to both sides of the rotating rod. A motor is suspended inside the top of the first housing by a support rod. The bottom of the motor is connected to a main shaft. The bottom of the main shaft extends to connect with the bottom internal rotating shaft of the mixing mechanism.

[0011] A first gear and a top plate are sequentially arranged from top to bottom on the top surface of the main shaft;

[0012] The outer surface of the first gear meshes with the outer surface of the second gear, and the outer surface of the top plate is slidably connected to the inner wall of the top of the feeding mechanism;

[0013] The surface of the top plate is provided with material cylinders arranged in a ring.

[0014] Preferably, the inner top wall of the feeding mechanism is provided with a groove corresponding to the outer edge of the top plate, and a sliding ball is fixedly connected to the outer edge of the top plate. The outer edge of the top plate is slidably engaged with the groove on the top of the feeding mechanism through the sliding ball.

[0015] Preferably, the inner wall of the material cylinder is fixedly connected to a first return spring in a ring-shaped arrangement from top to bottom. A circular ring is fixedly connected to one side of the first return spring, and a long rod is fixedly connected to the inner wall of the circular ring. An elliptical ball is provided at the top of the long rod.

[0016] Preferably, two push rods are fixedly connected to the top outer edge of the feeding mechanism, and a ball head is provided on one side of the push rod, with the top ball head of the push rod corresponding to the elliptical ball at the top of the material cylinder;

[0017] When the top rod meets one side of the long rod, the surface of the long rod will be squeezed by the ball head on one side of the top rod. After the top of the long rod passes the ball head on one side of the top rod, the first return spring inside the long rod will rebound and shake, loosely feeding the material inside the barrel.

[0018] Preferably, the main shaft is located in the inner area of ​​the feeding mechanism and is fixedly connected to the bent rod in a ring shape. The inner wall of one side of the bent rod is fixedly connected to the material cylinder, and an air bladder is added between the top plate surface and the outer edge of the material cylinder.

[0019] Preferably, the bottom inner wall of the feeding mechanism is provided with an extrusion mechanism, the top and bottom of the extrusion mechanism are fixedly connected to L rods, teeth are provided in the middle area of ​​the extrusion mechanism in the L rod, and a sliding groove is opened in the bottom inner wall of the feeding mechanism corresponding to the top of the L rod. The top and bottom of the extrusion mechanism are slidably engaged with the sliding groove of the bottom inner wall of the feeding mechanism through the L rod.

[0020] Preferably, a slot is provided on one side of the feeding mechanism corresponding to the surface of the third gear, and one side of the third gear meshes with the teeth on the surface of the extrusion mechanism through the slot of the feeding mechanism.

[0021] Preferably, rubber heads are arranged in a ring on the inner wall of the extrusion mechanism, and arc rods are fixedly connected to both sides of the rubber heads. The extrusion mechanism is fixedly connected to one side of the arc rods, and a second spring can be elastically connected to one side of the rubber heads and the inner wall of the extrusion mechanism.

[0022] When the rotating barrel encounters the surface of the rubber head, the roller surface rolls and squeezes the rubber head. Subsequently, after the roller continues to roll and separate from the rubber head, the surface of the rubber head rebounds and strikes the bottom surface of the barrel, causing vibration.

[0023] Preferably, a roller is fixedly connected to one side of the bottom of the material cylinder, and a roller is provided on the surface of the roller.

[0024] A method for preparing a farmland remediation agent includes the following steps:

[0025] Step 1: Pour the required farmland remediation agent materials into the inside of the cylinder, then start the motor to drive the main shaft, which in turn drives the first gear and the top plate to rotate clockwise.

[0026] Step 2: With the main shaft driving the top plate, the material cylinder is rotated. During the rotation of the material cylinder, the long rod inside the material cylinder will be squeezed and collided with one side of the top rod, causing the long rod to shake under the force of the first return spring, which loosens the material inside the material cylinder.

[0027] Step 3: During the clockwise rotation of the barrel, the second gear of the main shaft drive rod causes the third gear to drive the extrusion mechanism to change the direction of rotation with the barrel, and the extrusion mechanism drives the rubber head to rotate counterclockwise. Then, the rubber head and the roller squeeze each other, causing the rubber head to knock the bottom of the barrel to loosen the material.

[0028] Step 4: After the material falls into the mixing mechanism, the bottom of the main shaft will rotate to fully mix the water and material to prepare the repair agent. Finally, the staff will connect the branch pipe and open the valve on the outlet side for use.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0030] 1. When adding materials required for farmland remediation agents, workers can place the required mixed materials into the pipes of the corresponding material cylinders. This effectively allows for the simultaneous placement of different required materials, reducing the physical exertion of workers pouring materials one by one. Then, the motor is started, causing the motor-driven main shaft to rotate clockwise. During the rotation of the main shaft, the top plate and the material cylinder will rotate. With each rotation of the material cylinder, the convex ball at the top of the long rod inside will contact the top rod. When the long rod contacts the top rod, it will cause the first return spring to squeeze to one side. After the long rod and the top rod surface are separated by the squeeze, the long rod will cause the side squeezed by the first return spring to rebound and shake, causing the required materials inside the material cylinder to be loosened and discharged from the bottom mesh. This effectively ensures that the required materials are loosened and descended proportionally into the mixing mechanism inside each material cylinder.

[0031] 2. As the main shaft rotates, the first gear drives the second gear, which in turn drives the rotating rod and the third gear to rotate. Then, one side of the third gear drives the teeth on the surface of the extrusion mechanism through the corresponding opening of the feeding mechanism. This causes the extrusion mechanism to rotate in the opposite direction, causing the rubber head to squeeze and collide with the bottom roller of the clockwise rotating cylinder. This makes the rubber head strike the bottom of the cylinder, effectively making the bottom of the cylinder loosen and discharge material while the bottom outer surface is struck by the rubber head. This prevents the mesh from getting clogged during material discharge from the bottom of the cylinder, which would affect the normal material mixing. Attached Figure Description

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below 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.

[0049] like Figures 1 to 15 As shown, the present invention provides a farmland remediation agent preparation device, including a mixing mechanism 1, a feeding mechanism 2 fixedly connected to the top of the mixing mechanism 1, a second housing 4 fixedly connected to the top outer surface of the feeding mechanism 2 by a support rod, a first housing 3 fixedly added to one side of the feeding mechanism 2, and the bottom of the mixing mechanism 1 and the first housing 3 being stabilized by a support component. A discharge port 5 is fixedly connected to one side of the bottom of the mixing mechanism 1, a valve is provided on one side of the discharge port 5, and branch pipes 6 are branched and connected to the bottom of the discharge port 5.

[0050] Inside the first housing 3, a rotating rod 10 is connected to the rotating rod 10 via a support rod shaft on one side. The second gear 9 and the third gear 11 are connected to the two sides of the rotating rod 10 respectively. The motor 7 is suspended inside the top of the first housing 3 via a support rod. The bottom of the motor 7 is connected to the main shaft 13. The bottom of the main shaft 13 extends to connect with the rotating shaft inside the bottom of the mixing mechanism 1.

[0051] The first gear 8 and the top plate 14 are arranged sequentially from top to bottom on the top surface of the main shaft 13;

[0052] The outer surface of the first gear 8 meshes with the outer surface of the second gear 9, and the outer surface of the top plate 14 is slidably connected to the inner wall of the top of the feeding mechanism 2.

[0053] The surface of the top plate 14 is provided with material cylinders 12 arranged in a ring.

[0054] When using the farmland remediation agent, the required materials can be placed by the staff into the pipe of the corresponding material cylinder 12. This allows for the simultaneous placement of different required materials, reducing the physical exertion of staff having to pour each material individually.

[0055] like Figures 8 to 15 As shown, a groove is provided on the inner wall of the top of the feeding mechanism 2 corresponding to the outer edge of the top plate 14. A ball bearing 18 is fixedly connected to the outer edge of the top plate 14, and the outer edge of the top plate 14 is slidably engaged with the groove on the top of the feeding mechanism 2 through the ball bearing 18.

[0056] The inner wall of the material cylinder 12 is fixedly connected to the first return spring 20 in a ring from top to bottom. One side of the first return spring 20 is fixedly connected to the ring 19. The inner wall of the ring 19 is fixedly connected to the long rod 21. The top of the long rod 21 is provided with an elliptical ball.

[0057] Two push rods 15 are fixedly connected to the top outer edge of the feeding mechanism 2. A ball head is provided on one side of the push rod 15, and the top ball head of the push rod 15 is set with the corresponding elliptical ball at the top of the material cylinder 12.

[0058] When the top rod 15 meets one side of the long rod 21, the surface of the long rod 21 will be squeezed by the ball head on one side of the top rod 15. After the top of the long rod 21 passes the ball head on one side of the top rod 15, the first return spring 20 squeezed inside the long rod 21 will rebound and shake, loosely feeding the material inside the material cylinder 12.

[0059] In use, the motor 7 is started, causing the main shaft 13 to rotate clockwise. During the rotation of the main shaft 13, the top plate 14 and the material cylinder 12 will rotate together. For each rotation of the material cylinder 12, the convex ball at the top of the long rod 21 inside will contact the top rod 15. When the long rod 21 contacts the top rod 15, it will drive the first return spring 20 to squeeze to one side. After the long rod 21 and the surface of the top rod 15 are separated by the squeeze, the long rod 21 will drive the side squeezed by the first return spring 20 to rebound and generate a shaking, so that the required material inside the material cylinder 12 is loosened and discharged from the bottom mesh. This effectively makes the required material loosened and descended proportionally into the mixing mechanism 1 by the long rod 21 inside each material cylinder 12.

[0060] As further explained above, each time the long rod 21 and the top rod 15 meet and squeeze, the first return spring 20 rebounds and shakes. During this process, the compression between the first return springs 20 will squeeze and screen the powder material inside the material cylinder 12. This will cause small pieces of material in the powder inside the material cylinder 12 to be crushed by the squeeze of the first return springs 20, thereby reducing the blockage of the material hole by the lumpy powder material.

[0061] like Figure 7 As shown, the main shaft 13 is located in the inner area of ​​the feeding mechanism 2 and is fixedly connected to the bent rod 22 in a ring shape. The inner wall of one side of the bent rod 22 is fixedly connected to the material cylinder 12. An airbag 16 is added between the surface of the top plate 14 and the outer edge of the material cylinder 12.

[0062] The bottom inner wall of the feeding mechanism 2 is provided with an extrusion mechanism 23. The top and bottom of the extrusion mechanism 23 are fixedly connected to L rods 24. Teeth are provided in the middle area of ​​the extrusion mechanism 23 located in the L rods 24. A sliding groove is opened in the bottom inner wall of the feeding mechanism 2 corresponding to the top of the L rods 24. The top and bottom of the extrusion mechanism 23 are slidably engaged with the sliding groove of the bottom inner wall of the feeding mechanism 2 through the L rods 24.

[0063] A slot is provided on the surface of the third gear 11 on one side of the feeding mechanism 2, and one side of the third gear 11 meshes with the teeth on the surface of the extrusion mechanism 23 through the slot of the feeding mechanism 2.

[0064] Rubber heads 25 are arranged in a ring on the inner wall of the extrusion mechanism 23. Arc rods 26 are fixedly connected to both sides of the rubber heads 25. One side of the arc rods 26 is fixedly connected to the extrusion mechanism 23. One side of the rubber heads 25 can be elastically connected to the inner wall of the extrusion mechanism 23 with a second spring 27.

[0065] A roller 28 is fixedly connected to one side of the bottom of the material cylinder 12, and rollers are provided on the surface of the roller 28.

[0066] When the rotating barrel 12 encounters the surface of the rubber head 25, the surface of the roller 28 rolls and squeezes the rubber head 25. Subsequently, after the roller 28 continues to roll and separate from the rubber head 25, the surface of the rubber head 25 will rebound and strike the bottom surface of the barrel 12, causing vibration.

[0067] In use, when the main shaft 13 drives the top plate 14 and the material cylinder 12 to rotate clockwise, the first gear 8 on the surface of the main shaft 13 drives the second gear 9, which in turn drives the third gear 11 to drive the extrusion mechanism 23. This causes the extrusion mechanism 23 to rotate counterclockwise. When the material cylinder 12 rotates clockwise in conjunction with the extrusion mechanism 23 rotating counterclockwise, the rubber head 25 on the inner wall of the extrusion mechanism 23 and the roller 28 at the bottom of the material cylinder 12 will continuously squeeze and collide with each other. This causes the surface of the rubber head 25 to continuously strike the bottom surface of the material cylinder 12, and the bottom of the material cylinder 12 will vibrate due to the impact. At this time, the powder material that is difficult to discharge through the mesh at the bottom of the material cylinder 12 will be discharged quickly.

[0068] While the barrel 12 is vibrating, the upper part of the barrel 12 will also shake. At this time, the shaking of the upper part of the barrel 12 will be slowed down by the bent rod 22 and the air bag 16, so that the shaking amplitude of the barrel 12 is reduced and the shaking of the barrel 12 is prevented from colliding with the groove of the top plate 14.

[0069] The use of metal material for the overall surface of the barrel 12, as further explained above, is to ensure that the rubber head 25 produces an excellent vibration effect when striking the surface of the barrel 12.

[0070] To further explain, the bending rod 22 is made of rubber in order to reduce the amplitude of vibration when the barrel 12 vibrates due to the elasticity of the bending rod 22.

[0071] like Figures 9 to 10 As shown, the bottom of the main shaft 13 is fixedly connected to the roller brush 17 inside the mixing mechanism 1, and the surface of the roller brush 17 is in contact with the inner wall of the mixing mechanism 1.

[0072] When in use, after the material is fed into the material cylinder 12, it reaches the inside of the mixing mechanism 1. The bottom of the rotating main shaft 13 will fully stir it. During the stirring process, the roller brush 17 will also clean the inner wall of the mixing mechanism 1 to prevent the prepared farmland remediation agent from adhering to the inner wall of the mixing mechanism 1 and causing dirt.

[0073] After the required materials are prepared into farmland remediation agent, the staff will connect the round pipe to the branch pipe 6 and open the valve on one side of the discharge port 5 to discharge the remediation agent inside the mixing mechanism 1 for use.

[0074] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0075] 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.
