Description

Technical Field

[0001] This utility model relates to the field of water-soluble fertilizer technology, specifically a water-soluble fertilizer quality testing device. Background Technology

[0002] As is well known, water-soluble fertilizer is a multi-element compound fertilizer that can be completely dissolved in water. It can be easily absorbed by crops and has a relatively high absorption and utilization rate. In the production process, quality testing devices are needed to test the water-soluble fertilizer.

[0003] Chinese Utility Model Publication No. CN216144591U discloses a water-soluble fertilizer quality testing device, including a mixing tank. A first motor is fixedly installed on the top of the mixing tank. A stirring blade that penetrates the top of the mixing tank and extends into the mixing tank is fixedly installed on the output shaft of the first motor. A drive box is fixedly installed on the bottom of the mixing tank. A second motor is fixedly installed on the left side inside the drive box. A fixing plate is fixedly installed on the right side of the second motor. A first baffle is fixedly installed on the top right side of the fixing plate. A second baffle is fixedly installed on the bottom right side of the fixing plate. A bidirectional threaded rod that penetrates the fixing plate and is located between the first and second baffles is fixedly installed on the output shaft of the second motor. Two sliders are threadedly connected to the left and right sides of the bidirectional threaded rod. A drive rod that penetrates the drive box and the mixing tank and extends into the mixing tank is fixedly installed on the top of each of the two sliders. A push plate is fixedly installed on the opposite side of each of the two drive rods. A telescopic rod that is fixedly connected to the mixing tank is fixedly installed on the opposite side of each of the two push plates.

[0004] Although the device uses the rotation of the second motor to drive the pusher plate to move water and fertilizer towards the mixing blades, when the second motor drives the pusher plate towards the side wall of the mixing tank, due to its large surface area, the pusher plate will move a large amount of water and fertilizer close to the mixing blades to the side wall of the mixing tank under the disturbance of the pusher plate. This reduces the amount of fertilizer remaining at the mixing blades, so its practicality is not very good and there is room for improvement. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a water-soluble fertilizer quality testing device, which has the advantage of improved practicality.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a water-soluble fertilizer quality testing device, comprising a mixing tank and a filter tank. The lower part of the mixing tank is provided with several sliding grooves, each of which is slidably connected to a slider. The lower part of each slider is provided with threaded holes, which are arranged in reverse threads. The threaded holes are threadedly connected to a screw. A first motor is installed on one side of the screw. The upper part of each slider is provided with a first push plate for pushing the fertilizer towards the center of the mixing tank. Second push plates are rotatably connected to both sides of the first push plate.

[0009] Furthermore, the side wall of the first pusher plate near the side wall of the mixing tank is provided with several support plates. When the slider drives the first pusher plate and the second pusher plate to move towards the center of the mixing tank, one side of the second pusher plate is attached to the support plate. The side wall of the first pusher plate near the center of the mixing tank is provided with several limiting plates.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a water-soluble fertilizer quality testing device, which has the following beneficial effects:

[0016] In this water-soluble fertilizer quality testing device, the first and second pushing plates are horizontal when pushing fertilizer towards the center of the mixing tank. This results in a large unfolded area and a large contact area with the water and fertilizer in the direction of movement, facilitating the movement of a large amount of fertilizer to the center of the mixing tank. When the first and second pushing plates move towards the side wall of the mixing tank, the second pushing plate rotates and comes into contact with the limiting plate. At this time, the unfolded area of ​​the first and second pushing plates is small, and the contact area with the water and fertilizer in the direction of movement is small. This only drives a small amount of water and fertilizer to move towards the side wall of the mixing tank, increasing the amount of water and fertilizer retained in the center of the mixing tank, thereby improving its practicality.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6This utility model discloses a water-soluble fertilizer quality testing device, comprising a mixing tank 1 and a filter tank 2. The lower part of the mixing tank 1 is provided with several sliding grooves 3, each slidably connected to a slider 4. The lower part of each slider 4 is provided with threaded holes arranged in reverse threads. A screw 5 is threadedly connected to each threaded hole. When the screw 5 rotates, it can drive the sliders 4 to move closer or further apart. A first motor 6 is installed on one side of the screw 5. Starting the first motor 6 causes the screw 5 to rotate, which in turn drives the threaded sliders 4 to slide within the sliding grooves 3. A first push plate 7 is provided on the upper part of each slider 4 to push the fertilizer towards the center of the mixing tank 1. Second push plates 8 are rotatably connected to both sides of the first push plate 7, working in conjunction with the first push plate 7 to push the fertilizer near the side wall of the mixing tank 1 to the center of the mixing tank 1.

[0026] Several support plates 9 are provided on the side wall of the first push plate 7 near the side wall of the mixing tank 1. When the slider 4 drives the first push plate 7 and the second push plate 8 to move towards the center of the mixing tank 1, one side of the second push plate 8 is attached to the support plate 9. At this time, it is horizontal with the first push plate 7, so that the area is maximized when pushing fertilizer. Several limiting plates 10 are provided on the side wall of the first push plate 7 near the center of the mixing tank 1. When the slider 4 drives the first push plate 7 and the second push plate 8 to move away from the center of the mixing tank 1, the second push plate 8 collides with the water and fertilizer in the mixing tank 1 and is pushed by the water and fertilizer to the limiting plate 10. At this time, the second push plate 8 and the first push plate 7 are in an inclined state, and the contact area with the water and fertilizer in the direction of movement is reduced, so the amount of water and fertilizer pushed is less.

[0027] The second pusher plate 8 is provided with several through holes 11, all of which are inclined. When the second pusher plate 8 moves towards the center of the mixing tank 1, the direction of the through holes 11 and the direction of movement of the second pusher plate 8 are inclined, so that when the second pusher plate 8 moves, the water and fertilizer collide with the side wall of the through holes 11, generating a pushing force on the water and fertilizer and pushing it to the center of the mixing tank 1. When the second pusher plate 8 moves away from the center of the mixing tank 1, the direction of the through holes 11 and the direction of movement of the second pusher plate 8 are horizontal, so that the water and fertilizer can pass smoothly through the through holes 11 without obstruction, thereby reducing the pushing force generated on the water and fertilizer when the second pusher plate 8 moves towards the side wall of the mixing tank 1. The edges of the second pusher plate 8 are rounded, which helps to reduce the impact force of the rotating water and fertilizer hitting the edge of the second pusher plate 8, thereby reducing the resistance generated on the rotating water and fertilizer.

[0028] The first push plate 7 has several through slots 12 on its side wall, and each slot is connected to a guide rod 13. One side of each guide rod 13 is fixedly connected to the side wall of the mixing tank 1. When the first push plate 7 moves with the slider 4, the guide rod 13 and the first push plate 7 move relative to each other, so that the first push plate 7 moves along the axis of the guide rod 13.

[0029] A stirring rod 14 is rotatably connected to the middle of the mixing tank 1. A second motor 15 is installed on the upper part of the stirring rod 14. When the second motor 15 is started, it rotates, driving the stirring rod 14 to rotate, and then the fertilizer and water are mixed.

[0030] The upper part of the filter box 2 is equipped with a control box 16, which is electrically connected to the first motor 6 and the second motor 15. The operator controls the first motor 6 to rotate forward and backward through the control box 16, and controls the second motor 15 to rotate forward to stir the water and fertilizer.

[0031] In this embodiment, the first motor 6, the second motor 15, and the control box 16 are all commercially available conventional devices known to those skilled in the art. In this patent, we are simply using them without making any improvements to their structure or function. Their setting method, installation method, and electrical connection method can be easily explained by those skilled in the art by following the instructions for use. Therefore, we will not elaborate on them here.

[0032] In summary, when using this water-soluble fertilizer quality testing device, after adding water and fertilizer to the mixing tank 1, the operator starts the second motor 15. The second motor 15 rotates, driving the stirring rod 14 to rotate and mix the water and fertilizer. Then, the first motor 6 is started, rotating in the forward direction and driving the screw 5 to rotate. This causes several sliders 4 and the first push plate 7 to move closer together, pushing the fertilizer pushed by the stirring rod 14 to the side wall of the mixing tank 1 towards the center of the mixing tank 1. At this time, the end face of the second push plate 8 near the center of the mixing tank 1 collides with the water and fertilizer, and the left side of the push plate 8 is in contact with the end face of the support plate 9. During the movement, the fertilizer between the second push plate 8 and the center of the mixing tank 1 and the side wall of the through hole 11 of the second push plate 8 collide. The collision creates resistance, which drives some of the water and fertilizer towards the center of the mixing tank 1. When the slider 4 slides to the other side of the chute 3, the first motor 6 rotates in the opposite direction, driving the screw 5 to reverse, which in turn drives the slider 4 and the first push plate 7 to move towards the side wall of the mixing rod 14. The end face of the second push plate 8 facing the side wall of the mixing tank 1 collides with the water and fertilizer and is pushed to the limiting plate 10. At this time, the second push plate 8 and the first push plate 7 are set at an angle, and the water and fertilizer flow smoothly along the through hole 11 of the second push plate 8 to the other side of the second push plate 8 without generating resistance, until the slider 4 moves to the side wall of the chute 3 near the mixing tank 1. This cycle continues, pushing the fertilizer to the center of the mixing tank 1 for mixing until the water and fertilizer are completely mixed.

[0033] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
