Technical Field

[0001] This utility model relates to the field of fertilizer technology, and in particular to a fertilizer mixing and filling device. Background Technology

[0002] Modern fertilizers come in many varieties and can be classified according to their uses as nitrogen fertilizers, phosphate fertilizers, potassium fertilizers, compound fertilizers, organic fertilizers, and microbial fertilizers. These fertilizers are usually made by mixing a variety of raw materials. Different raw materials have different physical properties. For example, if high-density diammonium phosphate and light humic acid are not mixed thoroughly, they will separate into layers, resulting in inconsistent nutrient content in different batches of the final product and affecting the fertilization effect.

[0003] In existing technologies, a single stirring rod inside the tank typically drives the blades to rotate, thereby stirring the raw materials. This can easily create dead zones at the edges and bottom of the tank, resulting in some materials not being fully stirred. Furthermore, the multiple filling ports on the tank are sealed with plastic bags to control the opening of the filling ports, making it impossible to accurately control the flow rate. This can easily lead to inconsistent filling volumes and affect product quality. Therefore, a fertilizer stirring and filling device is proposed to solve the above-mentioned problems. Utility Model Content

[0007] Preferably, the filling mechanism further includes a feeding rack, which is fixedly connected to the top surface of the frame, and a filter screen is adhered to the inner wall of one feeding port of the feeding rack.

[0008] The above technical solution uses a feeding rack that is fixedly connected to the frame for feeding raw materials. The feeding rack has three feeding ports to facilitate the simultaneous feeding of multiple raw materials. A filter screen is attached to one feeding port to intercept large particles of impurities. The filter screen is attached for easy disassembly and replacement. The frame, feeding rack, and filter screen are all made of stainless steel, which is corrosion-resistant, easy to clean, and can extend the service life of the device.

[0009] Preferably, the filling tube with an electric valve is fixedly connected to the lower surface of the frame, and a button is provided on the outer surface of the filling tube, the button being electrically connected to the electric valve of the filling tube.

[0010] The above technical solution uses a filling tube that is fixedly connected to the frame, facilitating the filling of mixed materials into fertilizer bags.

The filling tube is also made of stainless steel. The electric valve can be a VAT2 series electric ball valve, which is compact, opens and closes quickly, and has good sealing performance. Specific models can be selected according to actual needs. A controller and a flow controller are also provided to ensure quantitative filling accuracy.

[0011] Preferably, the stirring mechanism further includes a motor, which is fixedly mounted on the right side surface of the frame, and the output shaft of the motor is rotatably connected to the inner wall of the right side groove of the frame through a bearing.

[0012] The above technical solution involves fixing the motor to the frame, with the motor's output shaft rotatably connected to the frame via bearings to ensure the stability of the motor's output shaft rotation. The motor model can be a YE3 series three-phase asynchronous motor, which is highly efficient, energy-saving, stable in operation, and suitable for continuous work. It is also equipped with a gearbox, reducer, and encoder to achieve precise control.

[0013] Preferably, the output shaft of the motor is fixedly mounted with a hollow tube, the hollow tube is rotatably connected to the inner wall of the frame via a bearing, and a fixing rod with a bevel gear is fixedly mounted on the left inner wall of the frame, the fixing rod being located inside the hollow tube.

[0014] The above technical solution involves fixing the output shaft of the motor to the hollow tube, driving the hollow tube to rotate. The hollow tube is rotatably connected to the frame via bearings, ensuring the stability of the hollow tube's rotation. The frame is fixedly installed to a fixing rod, which is located inside the hollow tube so that the bevel gear on the rod meshes with the bevel gear on the spiral rod of the hollow tube.

A button 31 is provided on the outer surface of the filling tube 3, and the button 31 is electrically connected to the electric valve of the filling tube 3. The fixed connection between the filling tube 3 and the frame 1 facilitates the filling of the mixed material into the fertilizer bag through the filling tube 3. The electric valve on the filling tube 3 controls the opening and closing of the filling tube 3. The button 31 on the filling tube 3 is electrically connected to the electric valve. By manually controlling the opening and closing of the electric valve, precise control of the filling volume is ensured. The filling tube 3 is also made of stainless steel. The electric valve can be a VAT2 series electric ball valve, which has a compact structure, quick opening and closing, and good sealing performance. The specific model can be selected according to actual needs. It is also equipped with a controller and a flow controller to ensure quantitative filling accuracy.

[0031] By setting up a filling mechanism, the quantitative filling and cutting of materials are controlled. The feeding rack 2 is equipped with three feeding ports, which facilitates the simultaneous input of multiple raw materials. A filter screen 21 is attached to one feeding port to intercept large particulate impurities. The button 31 on the filling tube 3 is electrically connected to the electric valve. The opening and closing of the electric valve is manually controlled to ensure accurate control of the filling volume. The electric valve can be a VAT2 series electric ball valve, which has a compact structure, quick opening and closing, and good sealing performance. It is also equipped with a controller and a flow controller to ensure quantitative filling accuracy. This solves the technical problem in the existing technology where the opening of multiple filling ports on the tank is controlled by a plastic sealing bag, which makes it impossible to accurately control the flow rate and easily leads to inconsistent filling volume, affecting product quality.

[0032] In order to achieve uniform mixing and conveying of materials, a stirring mechanism is provided inside the frame 1. The stirring mechanism includes a spiral rod 6 with a bevel gear. The spiral rod 6 achieves uniform mixing and conveying of materials through compound rotational motion.

[0033] To ensure the stability of the rotation of the output shaft of motor 4, the stirring mechanism also includes motor 4. Motor 4 is fixedly installed on the right side surface of frame 1. The output shaft of motor 4 is rotatably connected to the inner wall of the right side groove of frame 1 through bearings.

The model of motor 4 can be YE3 series three-phase asynchronous motor 4, which is highly efficient and energy-saving, stable in operation, and suitable for continuous operation. It is also equipped with a gearbox, reducer and encoder to achieve precise control.

[0034] To drive the hollow tube 5 to rotate, the output shaft of the motor 4 is fixedly mounted with the hollow tube 5. The hollow tube 5 is rotatably connected to the inner wall of the frame 1 via bearings. A fixing rod 51 with a bevel gear is fixedly mounted on the left inner wall of the frame 1. The fixing rod 51 is located inside the hollow tube 5 and is fixedly mounted to the hollow tube 5 via the output shaft of the motor 4 to drive the hollow tube 5 to rotate. The hollow tube 5 is rotatably connected to the frame 1 via bearings to ensure the stability of the rotation of the hollow tube 5. The fixing rod 51 is fixedly mounted to the frame 1 to fix it. The fixing rod 51 is located inside the hollow tube 5 so that the bevel gear on it can mesh with the bevel gear of the spiral rod 6 on the hollow tube 5. The hollow tube 5 and the fixing rod 51 are both made of stainless steel, which has high strength and corrosion resistance to ensure stable transmission.

[0035] To drive the blade 61 to revolve and rotate, a spiral rod 6 with bevel gears is rotatably connected to the curved surface of the hollow tube 5 via bearings. The bevel gears of the spiral rod 6 mesh with the bevel gears of the fixed rod 51. The blade 61 is fixedly mounted on the curved surface of the spiral rod 6 by fastening bolts. The spiral rod 6 is rotatably connected to the hollow tube 5 via bearings, driving its revolution without affecting its rotation. Through the meshing of the bevel gears of the spiral rod 6 and the bevel gears of the fixed rod 51, the spiral rod 6 is driven by the hollow tube 5 to revolve and rotate simultaneously. The blade 61 is fixed by fastening bolts. The screw rod 6 is fixedly installed to facilitate disassembly and installation. The number and angle of the blades 61 can be adjusted according to the material characteristics. When the material is being stirred, the revolution and rotation of the screw rod 6 drive the blades 61 to revolve and rotate simultaneously, forming a multi-directional stirring flow field. The material is subjected to multi-directional shearing, tumbling and conveying in the tank, resulting in high mixing uniformity and high stirring efficiency. After the material is mixed, the rotation speed of the screw rod 6 can be adjusted during subsequent filling to achieve orderly material conveying, avoid material residue, and ensure the continuity and stability of the filling process.

[0036] By setting up a stirring mechanism, uniform mixing and conveying of materials are achieved. The motor 4 drives the hollow tube 5 to rotate, and the bevel gear of the spiral rod 6 meshes with the bevel gear of the fixed rod 51, so that the spiral rod 6 is driven by the hollow tube 5 to revolve and rotate at the same time. When stirring the materials, the revolution and rotation of the spiral rod 6 drive the blades 61 to revolve and rotate at the same time, forming a multi-directional stirring flow field. The materials are subjected to multi-directional shearing, tumbling and conveying in the tank, resulting in high mixing uniformity and high stirring efficiency. After the materials are mixed, the rotation speed of the spiral rod 6 can be adjusted during subsequent filling to achieve orderly conveying of materials, avoid material residue, and ensure the continuity and stability of the filling process. This solves the technical problem in the prior art, where a single stirring rod in the tank usually drives the blades 61 to revolve and then stir the raw materials, which easily forms dead corners at the edge and bottom of the tank, resulting in some materials not being fully stirred.

[0037] Working principle: When it is necessary to stir the materials, the staff can simultaneously put in different raw materials through the three feeding ports of the feeding rack 2 to ensure that the raw materials are put in according to the set ratio. One of the feeding ports has a built-in filter screen 21 to intercept large particles of impurities.

[0038] After the raw materials are added, the control system issues a command to start the motor 4. The motor is adjusted to the set speed through the reducer and gearbox. At this time, the hollow tube 5 is in a high-speed rotating state. The spiral rod 6 on the hollow tube 5 meshes with the fixed rod 51 through the bevel gear, so that it revolves around the center and rotates on its own axis. The blades 61 on the spiral rod 6 are fixed by fastening bolts and rotate with the spiral rod 6. The high-speed rotation of the spiral rod 6 and the blades 61 produces a strong shearing, tumbling and diffusion effect on the material. The material is quickly dispersed and mixed in the tank to prevent agglomeration and achieve uniform mixing. At this time, the material is in a highly turbulent state with high mixing efficiency, but the conveying direction is not strong. The control system monitors the speed through the encoder and controls the stirring time through the timer to ensure that the material is mixed evenly.

[0039] After mixing, the staff places the opening of the fertilizer bag onto the filling outlet of the filling tube 3. The control system adjusts the rotation speed of the hollow tube 5 to a low speed. At this time, the rotation and revolution speed of the screw rod 6 slows down, and the force of the screw blades on the material changes from shearing to pushing. Under the pushing of the screw blades, the material moves orderly along the spiral direction of the screw rod 6. The staff presses the button 31 on the filling tube 3. The controller receives the signal from the button 31 and starts the electric valve. The flow sensor monitors the filling volume in real time. After the set value is reached, the electric valve automatically closes. The control system can control the opening and closing of each filling tube 3 synchronously or sequentially to improve filling efficiency. After filling is completed, the control system automatically stops the rotation of the motor 4 and the screw rod 6. The staff disassembles the filter screen 21 and the blades 61 for cleaning to ensure that there is no residual material. The control system records the production data for easy traceability.

[0040] The connecting bearings of hollow tube 5 and frame 1, and the connecting bearings of spiral rod 6 and hollow tube 5, need to be lubricated regularly. The bevel gear meshing joint between spiral rod 6 and fixed rod 51 needs to be lubricated regularly. The lubrication status of the connection between motor 4 output shaft and reducer needs to be checked regularly.

[0041] Regularly check the operating status of motor 4, whether the electric valve opens and closes normally, check the bearing temperature and gear meshing noise, add grease if necessary, regularly disassemble filter screen 21 and blade 61 for thorough cleaning, check whether the fastening bolts are loose, regularly replace aging bearings and seals, and check the insulation performance of motor 4.

[0042] Temperature sensors can be installed on the inner wall of frame 1 as needed to monitor material temperature, and an alarm can be installed on the top of the control cabinet for fault alarm.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
