Description

Technical Field

[0001] This utility model belongs to the field of silo technology, and specifically relates to an automated weighing silo. Background Technology

[0002] Weighing silos are devices used for storing and measuring materials. They are widely used in industrial production. For example, in the production of ceramsite sand, various raw materials such as clay, shale, and fly ash are required. Weighing silos can accurately measure and store large quantities of raw materials, providing a stable supply of materials for production and avoiding production interruptions due to raw material shortages.

[0003] Existing weighing silos typically involve installing pressure sensors on the silo's support structure. When material enters the silo through the inlet, the weighing sensors measure the weight of the silo and the material in real time and transmit the weight signal to the control system. For example, Chinese patent CN215885591U discloses a silo with foot-mounted weighing functionality. Each foot has a weighing sensor at its lower end, and these sensors are connected to a display instrument to obtain the weight of the material inside the silo. However, in this design, placing the weighing sensors at the bottom of the feet means they must withstand the weight of the support, silo, and all other components for extended periods, accelerating their wear and tear. Utility Model Content

[0004] The purpose of this invention is to overcome the defects in the existing technology and provide an automated weighing silo.

[0005] This utility model provides an automated weighing hopper, including a hopper body, the upper part of which is a cylindrical cavity and the lower part of which is a conical cavity; an annular connecting plate is provided at the connection between the cylindrical cavity and the conical cavity, a bracket is provided at the bottom of the annular connecting plate, and a support is provided at the bottom of the bracket, with the bracket and the support being movably connected.

[0006] The support is equipped with a weighing component inside and a pressure sensor is installed on the side wall of the support. The weighing component is used to support the support and, under the gravity of the support, causes the weighing component to squeeze the pressure sensor.

[0007] The pressure sensor is connected to an external controller, which is used to acquire the parameters of the pressure sensor.

[0008] A further embodiment is that the support is a hollow structure, and the weighing component includes a fixing block with a semi-circular cross-section, the arc surface of which is fixedly connected to the support.

[0009] The fixing block has a rectangular groove along the vertical direction, and a slider is provided inside the rectangular groove. The slider has a trapezoidal structure and is slidably connected to the rectangular groove.

[0010] A support rod is provided at the top of the slider, and the support rod is connected to the bracket;

[0011] A groove is formed on one side surface of the slider, and a through hole is formed on the vertical surface of the fixed block. A linkage rod is provided in the through hole. One end of the linkage rod is inclined and slidably connected to the groove, so that when the fixed block moves vertically, the linkage rod slides horizontally in the through hole. The other end of the linkage rod is provided with a contact, and the position of the pressure sensor is adapted to the contact.

[0012] A further option is that the cross-section of the inclined groove is an L-shaped structure.

[0013] A further embodiment is that the slope of the inclined groove is the same as the slope of the inclined surface of the linkage rod.

[0014] A further embodiment is that a spring is provided at the bottom of the slider, with the top of the spring connected to the slider and the bottom of the spring connected to the bottom of the support.

[0015] A further embodiment is that ear plates are provided on both sides of the support rod, the bracket includes four support columns, each support column is provided with a support at its bottom, each support column is connected to the annular connecting plate at its top, a reinforcing beam is provided between two adjacent support columns, and an oblique support is provided between the reinforcing beam and the annular connecting plate.

[0016] Each of the support columns has a blind hole at its bottom, and a sliding groove adapted to the ear plate is formed on both sides of the blind hole. The ear plate is slidably connected to the sliding groove.

[0017] The depth of the blind hole is less than the length of the support rod.

[0018] A further embodiment is that each of the supports is provided with a reinforcing plate at its bottom, and the reinforcing plate is fixed to the ground by bolts;

[0019] Each of the support columns is fitted with a collar, and the collar is slidably connected to the support column;

[0020] A plurality of connecting rods are evenly arranged around the collar. One end of each connecting rod is connected to the collar, and the other end of the connecting rod is connected to the edge of the reinforcing plate.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] This invention features a pressure sensor mounted on the side wall of the support, and the support and bracket are movably connected. The pressure sensor is compressed by a weighing component to obtain the weight of the hopper, thereby reducing the vertical pressure of the bracket on the hydraulic sensor and extending the service life of the pressure sensor.

[0023] This invention features a useful spring at the bottom of the slider, which can balance the weight of the support bracket and the hopper when it is empty. When the material enters the hopper, the support bracket continues to compress the spring, causing the linkage rod to move towards the pressure sensor, thereby applying horizontal pressure to the pressure sensor and reducing the force cycle of the pressure sensor.

[0024] This utility model features a reinforcing plate at the bottom of the support and a collar on the support column. The reinforcing plate and the collar are connected by a connecting rod, which enhances the stability of the support's vertical movement. Attached Figure Description

[0031] To make the objectives, technical solutions, design methods, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this utility model.

[0032] like Figure 1As shown, this utility model provides an automated weighing hopper, including a hopper body 1.

The pressure sensor 14 is connected to an external controller, and the controller is used to acquire the parameters of the pressure sensor 14.

[0033] like Figure 2 As shown, the support 4 has a hollow structure, and the weighing component includes a fixing block 8 with a semi-circular cross-section. The arc surface of the fixing block 8 is fixedly connected to the support 4, allowing a certain gap to be formed between the fixing block 8 and the inner wall of the support 4. A rectangular groove 9 is formed vertically on the fixing block 8, and a slider 10 with a trapezoidal structure is disposed inside the rectangular groove 9. The slider 10 is slidably connected to the rectangular groove 9. A support rod 15 is provided at the top of the slider 10, and the support rod 15 is connected to the bracket 2. The slider 10... A groove 11 is formed on one side surface, and a through hole is formed on the vertical surface of the fixing block 8. A linkage rod 12 is provided in the through hole. One end of the linkage rod 12 is inclined and slidably connected to the groove 11, so that when the fixing block 8 moves vertically, the linkage rod 12 slides horizontally in the through hole. The other end of the linkage rod 12 is provided with a contact 13. The position of the pressure sensor 14 is adapted to the contact 13, so that when the linkage rod 12 moves horizontally, the contact 13 can abut against the pressure sensor 14 and apply a lateral compressive force to the pressure sensor 14.

[0034] In this embodiment, the cross-section of the inclined groove 11 is L-shaped and the slope of the inclined groove 11 is the same as the slope of the inclined surface of the linkage rod 12.
