[0027] 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.

[0028] Please see Figure 1-4 This utility model provides a new technical solution: a precision weighing device for compound fertilizer, including a material conveyor belt 1, and a weighing frame 2 is provided on the right surface of the material conveyor belt 1.

[0029] The weighing frame 2 is equipped with a weighing mechanism, which includes a diversion conveyor belt 3, a first hydraulic actuator 4, a first hydraulic rod 5, a diversion frame 6, a fixed frame 7, a first conveyor belt 8, a second conveyor belt 9, a weight display module 10, a weight detection module 11, a weighing conveyor belt 12, a vertical plate 13, a second hydraulic actuator 14, a second hydraulic rod 15, and a guide plate 16.

[0030] Furthermore, the weight display module 10 is fixedly installed on the front surface of the crossbeam of the weighing frame 2, and the four weight detection modules 11 are respectively fixedly installed on the upper surface of the four uprights of the weighing frame 2. All four weight detection modules 11 are electrically connected to the weight display module 10.

[0031] The weighing conveyor belt 12 is installed on the upper surface of the four weight detection modules 11.

[0032] Furthermore, the diverter frame 6 is set on the right surface of the weighing conveyor belt 12, and two first hydraulic units 4 are rotatably connected to the right surface of the crossbeam of the diverter frame 6.

[0033] Furthermore, the two first hydraulic rods 5 are slidably sleeved on the inner surfaces of the two first hydraulic actuators 4, and the diversion conveyor belt 3 is rotatably connected to the upper ends of the two first hydraulic rods 5.

[0034] Furthermore, the fixing frame 7 is set on the right surface of the diversion conveyor belt 3, and the first conveyor belt 8 is fixedly installed on the opposite sides of the four uprights of the fixing frame 7;

[0035] The second conveyor belt 9 is fixedly installed on the opposite sides of the four uprights of the fixed frame 7.

[0036] Furthermore, two vertical plates 13 are fixedly installed on the upper surface of the material conveyor belt 1, and two guide plates 16 are rotatably connected to the opposite sides of the two vertical plates 13.

[0037] Furthermore, the two second hydraulic rods 15 are rotatably connected to the opposite sides of the two guide plates 16, the two second hydraulic actuators 14 are slidably sleeved on the outer surfaces of the two second hydraulic rods 15, and the two second hydraulic actuators 14 are rotatably connected to the opposite sides of the two vertical plates 13.

[0038] In use, this precision weighing device for compound fertilizer conveys the compound fertilizer via a material conveyor belt 1. By activating two second hydraulic actuators 14, the two actuators drive two second hydraulic rods 15, which are slidably mounted on their inner surfaces, to move towards their opposite faces. At this time, the two second hydraulic rods 15 apply a thrust to two guide plates 16 rotatably connected at their opposite ends, causing them to gradually tilt towards their opposite faces. The guide plates 16 then limit the movement of the compound fertilizer, ensuring it is accurately conveyed to the center of the weighing conveyor belt 12. The weight detection module 11 detects the weight of the compound fertilizer placed on the weighing conveyor belt 12. The weight data is transmitted to the weight display module 10 for display. At this time, the weighing conveyor belt 12 transports the compound fertilizer to the diversion conveyor belt 3. When the compound fertilizer that has passed the weight test is detected, it is transported by the first conveyor belt 8. When the weight does not meet the standard, the first hydraulic device 4 is activated. The first hydraulic device 4 applies a downward pulling force to the first hydraulic rod 5 that is slidably sleeved on the inner surface. The first hydraulic rod 5 applies a downward pulling force to the diversion conveyor belt 3 that is rotatably connected at the upper end. At this time, the diversion conveyor belt 3 is set at an angle and is aligned with the second conveyor belt 9. At this time, the compound fertilizer that does not meet the standard of the diversion conveyor belt 3 can be transported by the second conveyor belt 9.

[0039] This precision weighing device for compound fertilizer uses high-precision sensor technology in the weight detection module 11 to accurately detect the weight of the compound fertilizer placed on the weighing conveyor belt 12 and transmits the weight data to the weight display module 10 for display. When the weight of the compound fertilizer does not meet the standard, the compound fertilizer on its surface can be removed by adjusting the diversion conveyor belt 3 for recycling, facilitating efficient production. This precision weighing device for compound fertilizer uses a second hydraulic unit 14 to drive the guide plate 16 to be set at an inclination. The guide plate 16 guides the compound fertilizer on the material conveyor belt 1 to flow in a specific direction, so that the compound fertilizer is located at the center of the weighing conveyor belt 12 for weighing, which facilitates the provision of accurate weight data.

[0040] Structural Description:

[0041] Material conveyor belt 1: It is the basic component responsible for conveying compound fertilizer in the whole device. It is located at the beginning of the device. Its function is to transport compound fertilizer from the outside to the subsequent weighing and diversion links, provide material input for the entire weighing process, and ensure that compound fertilizer can continuously and stably enter the weighing device.

[0042] Weighing frame 2: As the supporting structure of the entire weighing mechanism, it is firmly installed on the right surface of the material conveyor belt 1. It provides a foundation and support for the installation of other components, ensuring the stability and reliability of the entire weighing mechanism, so that each component can operate in an orderly manner on its frame.

[0043] Diversion conveyor belt 3: Set on the diversion frame 6, supported by two first hydraulic rods 5 and adjustable in position, its main function is to divert the fertilizer before and after weighing the compound fertilizer according to actual needs, and transport the fertilizer to different subsequent processing lines or areas to realize the classified transportation of fertilizer.

[0044] The first hydraulic unit 4 is rotatably connected to the right surface of the crossbeam of the diverter frame 6. It provides power to the first hydraulic rod 5 through the hydraulic principle, driving the first hydraulic rod 5 to perform telescopic movement, thereby realizing precise control of the position and angle of the diverter conveyor belt 3 to meet different diverting requirements.

[0045] First hydraulic rod 5: Two first hydraulic rods 5 are respectively slidably sleeved on the inner surface of two first hydraulic units 4, and their upper ends are rotatably connected to the diversion conveyor belt 3. Driven by the first hydraulic unit 4, they can flexibly adjust the height and tilt angle of the diversion conveyor belt 3, thereby changing the diversion direction and conveying path of fertilizer.

[0046] Diverting frame 6: Installed on the right surface of the weighing conveyor belt 12, it serves as the mounting carrier for components such as the diverting conveyor belt 3 and the first hydraulic unit 4. It provides a stable support platform for the diverting operation, ensuring the stability and reliability of the diverting conveyor belt 3 during operation.

[0047] Fixing frame 7: Located on the right surface of the diversion conveyor belt 3, it is used to fix the first conveyor belt 8 and the second conveyor belt 9. It ensures that the two conveyor belts are fixed in position during operation, so that the fertilizer can be transported along the predetermined path, providing a stable conveying channel for subsequent fertilizer processing.

[0048] First conveyor belt 8: Fixedly installed on the opposite sides of the four uprights of the fixed frame 7. It is mainly responsible for further conveying the compound fertilizer diverted from the diversion conveyor belt 3, and transporting the fertilizer to a specific location, which may be for packaging, storage or other subsequent processing.

[0049] The second conveyor belt 9 is also fixedly installed on the opposite sides of the four uprights of the fixed frame 7. Similar to the first conveyor belt 8, it is also used to transport fertilizer, possibly to transport fertilizer to different processing areas, or to cooperate with the first conveyor belt 8 to realize the classification, transportation and processing of fertilizer.

[0050] Weight display module 10: It is fixedly installed on the front surface of the crossbeam of the weighing frame 2 and is used to display the weighing result of compound fertilizer in real time. The operator can intuitively understand the weight of the fertilizer being weighed by observing the weight display module 10 so as to perform corresponding operations and record.

[0051] Weight detection modules 11: There are four in total, which are fixedly installed on the upper surface of the four uprights of the weighing frame 2 and are all electrically connected to the weight display module 10. They use high-precision sensor technology to accurately detect the weight of the compound fertilizer placed on the weighing conveyor belt 12 and transmit the weight data to the weight display module 10 for display.

[0052] Weighing conveyor belt 12: Located on the upper surface of the four weight detection modules 11, it is a component that carries the compound fertilizer to be weighed. When the compound fertilizer passes on the weighing conveyor belt, the weight detection module 11 can accurately measure its weight. At the same time, the weighing conveyor belt 12 also plays the role of transporting the fertilizer through the weighing area.

[0053] Vertical plates 13: Fixedly installed on the upper surface of the material conveyor belt 1, they provide mounting and support positions for the guide plate 16 and related hydraulic components, ensuring the stability and reliability of the guide structure.

[0054] The second hydraulic actuator 14 is rotatably connected to the opposite surfaces of the two vertical plates 13 and slidably sleeved on the outer surfaces of the two second hydraulic rods 15. It drives the second hydraulic rods 15 through hydraulic power to control the angle and position of the guide plate 16.

[0055] Second hydraulic rod 15: Two second hydraulic rods 15 are rotatably connected to the opposite sides of the two guide plates 16 respectively. Driven by the second hydraulic device 14, they perform telescopic movements, thereby driving the guide plates 16 to change their angle. By adjusting the angle of the guide plates 16, the flow direction of fertilizer on the material conveyor belt 1 can be guided and controlled.

[0056] The guide plate 16 is mainly used to adjust the angle as needed to guide the compound fertilizer on the material conveyor belt 1 to flow in a specific direction, such as guiding the fertilizer to the weighing conveyor belt 12 for weighing, or guiding the fertilizer to bypass the weighing area to achieve different material conveying paths.

[0057] 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.
