Description

Technical Field

[0001] The utility model relates to the field of fertilizer water absorption testing, in particular to a device for measuring the water absorption of a water-retaining high-efficiency slow-release fertilizer. Background Art

[0002] The fertilizer water absorption measuring device is a device used to measure the water absorption of fertilizers. It is usually used to measure the amount of water absorbed by fertilizers. The device can be used in the fields of agriculture and horticulture to help farmers and gardeners understand the water absorption performance of fertilizers, so as to better manage the growth of plants.

[0003] A Chinese patent with publication number CN219552171U discloses a device for measuring the water absorption of a water-retaining slow-release fertilizer, comprising a turntable, a round pin fixedly arranged on the front side of the turntable, one end of the round pin extending to the inner side of a push-pull ring, and a second transmission mechanism arranged between the rear end of a rotating rod and a screw rod. The second transmission mechanism drives the rotating rod to rotate, so that the turntable drives the round pin to rotate with the rotating rod as the axis, that is, the round pin reciprocates to push and pull the push-pull ring, that is, it can drive the screen to move reciprocally, that is, it can vibrate the screen during filtering to prevent the screen from being blocked as much as possible.

[0004] The water-retaining slow-release fertilizer water absorption measuring device of the above patent achieves efficient drainage through shaking during the measurement and drainage process, and the shaking will produce a lot of noise, causing the water inside the water tank to splash due to the shaking. On the other hand, the horizontal reciprocating shaking alone can only meet the detection of smaller fertilizers. When detecting a large amount of fertilizer at a time, relying solely on the horizontal reciprocating shaking cannot completely avoid the blockage of the screen. Utility Model Content

[0005] The purpose of the utility model is to provide a water absorption measuring device for water-retaining high-efficiency slow-release fertilizers. Through the output of a motor and the transmission of a threaded rod, a container formed by a first screen, a second screen and a third screen can be longitudinally adjusted in horizontal height while rotating. During the rotation, the fertilizer will be kept away from the second screen to avoid blockage that causes water to be unable to be discharged efficiently, thereby solving the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a device for measuring the water absorption of a water-retaining and high-efficiency slow-release fertilizer, comprising a water tank, a first screen is arranged at the upper end of the water tank, a third screen is arranged inside the first screen, and the third screen and the first screen are both columnar, four stirring blades are evenly distributed in an annular shape on the inner wall of the first screen, the upper end of the first screen and the upper end of the third screen are connected by a connecting frame, a threaded rod is arranged in the middle position of the upper end of the connecting frame, and a transmission ring is arranged at the upper end of the outer part of the threaded rod.

[0007] Preferably, the inner wall of the transmission ring is threadedly matched with the outer wall of the threaded rod, a connecting shaft for transmission is welded at the center position of the upper end of the threaded rod, a reserved cavity is provided on one side inside the transmission ring, a motor is provided at the lower end of the reserved cavity, and the output shaft of the motor is connected to the connecting shaft through a transmission belt.

[0008] Preferably, sliding cavities are provided on both sides of the reserved cavity, and both ends of the motor housing are connected to limiting frames by bolts, and the outside of the limiting frame is connected to the internal sliding groove of the sliding cavity.

[0009] Preferably, a second screen is provided at the lower end between the third screen and the first screen, and the second screen is an integral structure with the third screen and the first screen.

[0010] Preferably, the four stirring blades are all integrated with the first screen.

[0011] Preferably, the lower end of the connecting frame is an integral structure with the first screen and the third screen.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] When the utility model needs to take out the water-absorbed fertilizer after the fertilizer is soaked, the output of the motor drives the threaded rod to rotate after being driven by the transmission belt. The rotation of the threaded rod will drive the first screen, the second screen and the third screen connected to the lower end to rotate, and move vertically and longitudinally upward while rotating. The rotation will make the fertilizer stay away from the position of the third screen due to centrifugal force, so that the soaked liquid can flow out from the first screen position and can be discharged from the third screen position at the same time, avoiding that the fertilizer drives the filter position to be blocked when the liquid passes through the filter position, and the rotation and longitudinal vertical movement can improve the fertilizer taking-out efficiency and facilitate the use of the user. At the same time, the rotation of the first screen, the second screen and the third screen can avoid frequent collisions with the soaking liquid, and reducing collisions can avoid splashing of liquid, thereby improving the use environment of the equipment.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In order to solve the problem that the water absorption measuring device of the water-retaining slow-release fertilizer in the prior art achieves efficient drainage by shaking during the measurement and drainage process, and the shaking will produce a large noise, causing the water inside the water tank to splash due to the shaking, on the other hand, the horizontal reciprocating shaking alone can only meet the detection of smaller fertilizers. When a large amount of fertilizer is detected at a time, the clogging of the screen cannot be completely avoided by relying solely on the horizontal reciprocating shaking, this embodiment provides the following technical solutions:

[0022] A device for measuring the water absorption of a water-retaining and efficient slow-release fertilizer comprises a water tank 1. When measuring the water absorption of the fertilizer, the fertilizer needs to be immersed in a liquid within a set time, and the immersed liquid is preliminarily placed in the water tank 1. Figure 1 As shown, a first screen 2 is provided at the upper end of the water tank 1. The fertilizer to be tested is placed in the first screen 2 to complete the test. The first screen 2 and the fertilizer inside are placed in the liquid for soaking. When taking out the fertilizer, the first screen 2 is pulled out vertically. A support frame 8 for support is provided on one side of the outside of the water tank 1. The support frame 8 is perpendicular to the horizontal plane. The first screen 2 and the fertilizer inside can be moved to the outside of the soaking liquid after transmission through the support of the support frame 8. At the same time, the first screen 2 and the fertilizer inside can be supported by the support of the support frame 8 to be located in the water tank 1 for a long time, so as to achieve stable soaking.

[0023] In this embodiment, a third screen 16 is disposed inside the first screen 2, and both the third screen 16 and the first screen 2 are columnar. Figure 3As shown, a second screen 15 is provided at the lower end between the third screen 16 and the first screen 2, and the second screen 15, the third screen 16 and the first screen 2 are an integrated structure, and the two ends of the second screen 15 are used to connect the third screen 16 and the first screen 2, so that the first screen 2, the second screen 15 and the third screen 16 can carry and wrap the fertilizer, and through the screens in multiple directions, when draining, the liquid can be discharged from positions in different directions, thereby improving the drainage efficiency and avoiding the blockage of the screen at a single position, which causes the inability to complete normal discharge;

[0024] In this embodiment, four stirring blades 9 are evenly distributed on the inner wall of the first screen 2 in an annular shape, and the four stirring blades 9 are all integrated with the first screen 2. Figure 1 and Figure 3 As shown, the first screen 2 can quickly drive the internal fertilizer to rotate when it rotates due to the restriction of the protruding stirring blade 9. The fertilizer rotates around the first screen 2 to avoid the fertilizer approaching the third screen 16 in the middle position, thereby avoiding the blockage of the third screen 16. Avoiding the blockage can improve the drainage capacity and drainage efficiency.

[0025] In this embodiment, if Figure 1 and Figure 3 As shown, the upper end of the first screen 2 and the upper end of the third screen 16 are connected by a connecting frame 3, and the lower end of the connecting frame 3 and the first screen 2 and the third screen 16 are all integrated structures. The connection of the connecting frame 3 can facilitate pulling the connected screens and also facilitate driving the entire screen to rotate;

[0026] In this embodiment, a threaded rod 4 is provided at the middle position of the upper end of the connecting frame 3. Figure 4 As shown, a transmission ring 6 is provided at the upper end of the threaded rod 4, and the inner wall of the transmission ring 6 is threadedly matched with the outer wall of the threaded rod 4. Through the threaded match, the threaded rod 4 can drive the screen connected to the lower end to rotate and move vertically at the same time. The rotation and horizontal linear movement can be achieved by rotation, thereby reducing the manufacturing cost of the equipment.

[0027] In this embodiment, if Figure 5 As shown, a connecting shaft 14 for transmission is welded at the center position of the upper end of the threaded rod 4, a reserved cavity 7 is provided on one side inside the transmission ring 6, a motor 5 is provided at the lower end of the reserved cavity 7, and the output shaft of the motor 5 is connected to the connecting shaft 14 through a transmission belt 13, and the threaded rod 4 can be driven to rotate by starting the externally suspended motor 5 and through transmission;

[0028] In this embodiment, sliding cavities 11 are provided on both sides of the reserved cavity 7. Figure 2As shown, both ends of the motor 5 housing are connected to a limiting frame 10 by bolts, and the outside of the limiting frame 10 is connected to the internal sliding groove of the sliding cavity 11, and the movement of the motor 5 is limited by the sliding cavity 11, and the relative movement generated by the threaded fit is offset by the sliding cavity 11, so that the motor 5 is converted from a rotary motion to a longitudinal linear motion;

[0029] In this embodiment, if Figure 2 As shown, a connecting plate 12 is provided at the upper end between the output shaft of the motor 5 and the connecting shaft 14, and the two sides of the lower end of the connecting plate 12 are rotatably connected to the output shaft and the connecting shaft 14 respectively. Through the connection of the connecting plate 12 and the restriction of the sliding cavity 11, the motor 5 can move longitudinally along with the threaded rod 4.

[0030] Working principle: when using the device and soaking the fertilizer to be tested, pour the fertilizer into the container composed of the first screen 2, the second screen 15 and the third screen 16, and place it in the container to contact the liquid stored in the water tank 1. After soaking for a specified time, start the motor 5, and the output shaft of the motor 5 drives the connecting shaft 14 to rotate through the transmission belt 13. The rotation of the connecting shaft 14 can directly drive the threaded rod 4 to rotate. While the threaded rod 4 rotates, it will slide longitudinally inside the transmission ring 6. The rotation of the threaded rod 4 will drive the first screen 2 and the third screen 16 connected at the lower end to rotate through the connecting frame 3, and at the same time, it will pull the first screen 2, the third screen 16 and the second screen 15, so that the screen moves to the upper end outside the water tank 1, and pulls the fertilizer out to the outside of the soaking liquid. After being pushed by the stirring blade 9, the fertilizer rotates around the third screen 16. After rotation, the fertilizer can be kept away from the third screen 16 due to centrifugal force, avoiding blockage of the third screen 16, so that the liquid can be discharged normally and efficiently.
