Description

Technical Field

[0001] This application relates to the field of agricultural fertilizer technology, and in particular to a device for testing the caking performance of inorganic materials. 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 foundations of agricultural production. They mainly include ammonium phosphate fertilizers, water-soluble fertilizers containing macronutrients, fertilizers containing micronutrients, bio-fertilizers, organic fertilizers, and multi-dimensional energy-concentrated organic fertilizers, etc., and their processing requires the use of performance testing equipment.

[0003] Current fertilizer caking performance testing mainly involves pressing fertilizer under a ton bag in the workshop. There is currently no equipment that can be operated in a laboratory. Using a conventional bellows to test fertilizer caking performance may not result in the fertilizer caking due to insufficient pressure, making the test impossible. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides an inorganic material caking performance testing device, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.

[0005] To achieve the above objectives, this application adopts the following technical solution: an inorganic material caking performance testing device, comprising a housing, a through hole on the outer side of the housing, a fan and a filter screen installed on the inner wall of the through hole, a display screen fixedly installed on the outer side of the housing, a base plate fixedly installed on the inner bottom of the housing, four return springs symmetrically fixedly connected to the top of the base plate, and a lower pressure plate fixedly connected to the top of the four return springs, a pressing column fixedly installed at the bottom of the lower pressure plate, a pressure sensor fixedly installed in the middle of the top of the base plate, a nut fixedly installed on the top of the housing, a stud threadedly connected to the inner wall of the nut, an inner ring of a bearing fixedly connected to the outer edge of the bottom of the stud, and an upper pressure plate fixedly connected to the outer ring of the bearing.

[0006] In a preferred embodiment, the extrusion column is positioned above the pressure sensor.

[0007] By adopting the above technical solution, when fertilizer is placed on the top of the lower pressure plate, the upper pressure plate moves downward to squeeze the fertilizer, which in turn pushes the squeezing column downward to squeeze the pressure sensor, thereby transmitting pressure.

[0008] In a preferred embodiment, one end of a pipe is fixedly connected to the inner wall of the housing, and the other end of the pipe is fixedly connected to a locking valve. An air humidifier is fixedly installed on the outside of the locking valve.

[0009] By adopting the above technical solution, the air humidifier can be driven to generate moisture, which is then transmitted through pipes to the inner cavity of the chamber to change the humidity inside the chamber. The opening of the pipe can be controlled by the lock valve, thereby controlling the amount of moisture emitted.

[0010] In a preferred embodiment, a protective door is rotatably mounted on the outside of the housing, and a handle is fixedly mounted on the outside of the protective door. The protective door is made of transparent material.

[0011] By adopting the above technical solution, the opening of the box can be sealed, thereby ensuring the airtightness. Furthermore, since the protective door is made of transparent material, the test status inside the pressure plate can be viewed through the protective door when it is not opened.

[0012] In a preferred embodiment, a temperature and humidity sensor is fixedly installed on the inner wall of the enclosure, and the temperature and humidity sensor, pressure sensor, air humidifier and display screen are all electrically connected.

[0013] By adopting the above technical solution, the temperature and humidity status inside the chamber can be displayed on the screen, and the pressure status sensed by the pressure sensor can be transmitted to the screen in a timely manner, so that the staff can know it in time and improve the intelligence.

[0014] In a preferred embodiment, the stud has a hexagonal hole at its top, and a hexagonal post is inserted into the inner wall of the hexagonal hole. A rocker wheel is fixedly installed on the top of the hexagonal post.

[0015] By adopting the above technical solution, the rotating rocker wheel can drive the stud to rotate, thereby adjusting the height of the upper pressure plate, which can then be used to compress fertilizer placed on top of the lower pressure plate.

[0016] In a preferred embodiment, the top of the housing has a through hole, the stud is inserted through the inner wall of the through hole, and the nut is positioned corresponding to the through hole.

[0017] By adopting the above technical solution, it is possible to ensure that the stud will not interfere with the housing when rotating, thus ensuring the stability during rotation.

[0018] The beneficial effects of this application are:

[0019] 1. This inorganic material caking performance testing device uses a rotating rocker wheel to move the upper pressure plate downwards, adjusting the pressure applied to the fertilizer by the upper pressure plate. The pressure sensor at the bottom of the lower pressure plate then transmits the pressure exerted on the fertilizer in real time, and the pressure value can be promptly transmitted to the display screen, improving the accuracy of the test values.

[0020] 2. This inorganic material caking performance testing device generates moisture by driving an air humidifier, which is then transmitted through a pipe to the inner cavity of the chamber to change the humidity inside the chamber. The temperature and humidity sensor can monitor the temperature and humidity status inside the chamber in real time and transmit the temperature and humidity values ​​to the display screen for timely notification by the staff, thus improving the intelligence. The fan can promote air circulation inside the chamber. Attached Figure Description

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0028] Reference Figure 1-5 An inorganic material caking performance testing device includes a housing 1. A through hole 3 is provided on the outer side of the housing 1. A fan 4 and a filter screen 5 are installed on the inner wall of the through hole 3. A display screen 6 is fixedly installed on the outer side of the housing 1. A base plate 7 is fixedly installed on the inner bottom of the housing 1. Four return springs 8 are symmetrically fixedly connected to the top of the base plate 7. A lower pressure plate 10 is fixedly connected to the top of the four return springs 8. A pressing column 11 is fixedly installed at the bottom of the lower pressure plate 10. A pressure sensor 9 is fixedly installed in the middle of the top of the base plate 7. A nut 12 is fixedly installed on the top of the housing 1. A stud 21 is threadedly connected to the inner wall of the nut 12. The inner ring of a bearing 13 is fixedly connected to the outer edge of the bottom of the stud 21. An upper pressure plate 14 is fixedly connected to the outer ring of the bearing 13.

[0029] See Figure 4 The extrusion column 11 is positioned above the pressure sensor 9, so that when fertilizer is placed on the top of the lower pressure plate 10, the upper pressure plate 14 moves downward to extrude fertilizer, which in turn pushes the extrusion column 11 downward to extrude pressure sensor 9, thereby transmitting pressure.

[0030] See Figure 2 One end of a pipe 17 is fixedly connected to the inner wall of the housing 1, and the other end of the pipe 17 is fixedly connected to a lock valve 18. An air humidifier 19 is fixedly installed on the outside of the lock valve 18, so that the air humidifier 19 can be driven to operate and generate moisture, which is then transmitted to the inner cavity of the housing 1 through the pipe 17 to change the humidity inside the housing 1. The opening of the pipe 17 can be controlled by the lock valve 18, thereby controlling the amount of moisture emitted.

[0031] See Figure 1 A protective door 2 is rotatably installed on the outside of the housing 1. A handle is fixedly installed on the outside of the protective door 2. The protective door 2 is made of transparent material, which can seal the opening of the housing 1, thereby ensuring the airtightness. Furthermore, because the protective door 2 is made of transparent material, the test status inside the lower pressure plate 10 can be seen through the protective door 2 when it is not opened.

[0032] See Figure 2 and Figure 3 A temperature and humidity sensor 20 is fixedly installed on the inner wall of the housing 1. The temperature and humidity sensor 20, pressure sensor 9, air humidifier 19 and display screen 6 are all electrically connected, so that the temperature and humidity status of the inner cavity of the housing 1 can be displayed on the display screen 6. At the same time, the pressure status sensed by the pressure sensor 9 can be transmitted to the display screen 6 in a timely manner, so that the staff can know it in time and improve the intelligence.

[0033] See Figure 5 The stud 21 has a hexagonal hole at the top, and a hexagonal post 15 is inserted into the inner wall of the hexagonal hole. A rocker wheel 16 is fixedly installed on the top of the hexagonal post 15, so that rotating the rocker wheel 16 can drive the stud 21 to rotate, thereby adjusting the height of the upper pressure plate 14, which can then be used to squeeze fertilizer placed on top of the lower pressure plate 10.

[0034] See Figure 2 and Figure 5 The top of the housing 1 has a through hole, and the stud 21 is inserted through the inner wall of the through hole. The nut 12 is positioned corresponding to the through hole, which ensures that the stud 21 will not interfere with the housing 1 when rotating, thus ensuring the stability of the rotation.

[0035] Working principle: When using this device, the packaged fertilizer can first be placed on top of the lower pressure plate 10 inside the box 1. Then, the rocker wheel 16 is rotated to move the upper pressure plate 14 downward to adjust the pressure applied to the fertilizer by the upper pressure plate 14. Then, the squeezing column 11 at the bottom of the lower pressure plate 10 squeezes the pressure sensor 9 to transmit the pressure on the fertilizer in real time. The pressure value can be transmitted to the display screen 6 in time, and the air humidifier 19 is driven to run to generate moisture. The moisture is then transmitted to the inner cavity of the box 1 through the pipe 17 to change the humidity inside the box 1. The opening of the pipe 17 can be controlled by the locking valve 18 to control the amount of moisture discharged. The temperature and humidity sensor 20 can monitor the temperature and humidity status inside the box 1 in real time and can transmit the temperature and humidity values ​​to the display screen 6, so that the staff can know in time and improve the intelligence.
