Description

Technical Field

[0001] The utility model relates to the field of material level measurement, in particular to a structure for measuring storage material level. Background Art

[0002] At present, a Chinese utility model with the announcement number CN207036208U discloses a weight hammer level machine, which is used to measure the material height in the silo and various storage tanks. The weight hammer level machine includes a mechanical transmission component, an intelligent instrument and a hammer. The mechanical transmission component includes a box body, a pulley mechanism and a motor are arranged in the box body, and an outlet is arranged at the lower end of the box body. The pulley mechanism includes a reel, a counting wheel and a wire rope. The wire rope wound on the reel passes through the counting wheel and then extends out of the box body from the outlet of the box body. The end of the wire rope extending out of the box body is connected with a hammer. The motor drives the reel to rotate forward and reversely to realize the retracting and releasing action of the hammer. The box body is also equipped with a sensor I for sensing the number of rotations of the counting wheel and a sensor II for sensing whether the hammer needs to be retracted, so that the lowering height of the wire rope can be accurately measured, and the motor can be reversed in time to avoid damage to the motor when the hammer is buried or broken.

[0003] Although the existing measurement structure can measure the lowering height of the built-in hammer through external instruments, there are still other problems during use. For example, it does not have an internal cleaning function. The heavy hammer will cause an opening at the bottom of the shell during the lowering process, and the dust in the warehouse can enter the interior through the opening. In order to avoid excessive dust adhesion affecting the accuracy, personnel are required to open the shell regularly for cleaning. The operation is cumbersome and complicated, and it does not have a lifting function. When the heavy hammer is severely worn or needs to be replaced due to a fault, personnel are required to remove the entire equipment from above the warehouse, and then lift the equipment and turn it over before repairing it, which reduces the work efficiency of the personnel and has low practicality. In order to solve the above-mentioned problems, we propose a structure for warehouse material level measurement. Utility Model Content

[0004] The utility model aims to provide a storage material level measurement structure, which solves the problem that the existing material level measurement structure has no internal cleaning function and no lifting function.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: a structure for measuring storage material level, including a shell and a measuring mechanism, a fixed frame is welded inside the shell, an air inlet is opened on the top of the shell, a second motor is bolted to the inside of the fixed frame through a fixing part, a fan blade is fixedly sleeved on the output end of the second motor, a fixed box is arranged on the back side of the shell, a threaded rod is rotatably connected to the inside of the fixed box through a bearing, a third motor is fixedly sleeved on the other end of the threaded rod, a threaded plate is threadedly connected to the surface of the threaded rod, and the front side of the threaded plate is welded to the back side of the shell.

[0006] The above technical solution can have an internal cleaning function, which can facilitate the downward discharge of dust inside the shell, ensuring the accuracy of the material level measurement of the structure. At the same time, it can have a lifting function, which is simple and labor-saving to operate, reduces the workload of personnel, and is highly practical.

[0007] The utility model is further configured as follows: the measuring mechanism includes a reel, the reel is bolted to the inside of the shell, one end of the internal rotating shaft of the reel is fixedly sleeved with a first motor, a counting wheel is embedded on the front of the reel, a steel wire rope is connected to the surface of the internal rotating shaft of the reel, and the other end of the steel wire rope is connected to a hammer.

[0008] By adopting the above technical scheme, through the setting of the reel, the first motor, the counting wheel, the wire rope and the hammer, the material level in the warehouse can be understood in combination with the external instrument, and the first motor and the counting wheel are started. After the first motor is started, the wire rope and the hammer will be lowered through the cooperation of the reel. After the hammer is lowered to the bottom, it will contact the material in the warehouse. When the hammer contacts the material, the counting wheel will transmit the lowering height of the wire rope to the external instrument, and the material level inside the warehouse can be checked through the display screen of the external instrument.

[0009] The utility model is further configured as follows: a dustproof net is bolted to the top of the shell, and the diameter of the dustproof net is greater than the diameter of the air inlet.

[0010] By adopting the above technical solution, the dustproof net can be provided to prevent dust in the air from entering the interior of the housing through the air inlet.

[0011] The utility model is further configured as follows: the fan blades are made of PBT material.

[0012] By adopting the above technical solution, the fan blades have good characteristics of heat resistance, flame retardancy and electrical insulation.

[0013] The utility model is further configured as follows: two slide rails are bolted inside the fixed box, and sliding blocks slidably connected to the slide rails are welded on both sides of the threaded plate.

[0014] By adopting the above technical solution, the threaded plate can be limited by setting the slide rail and the slider to prevent the threaded plate from rotating during the up and down movement.

[0015] The utility model is further configured as follows: mounting plates are welded on both sides of the fixing box, and mounting holes are opened on the tops of the mounting plates.

[0016] By adopting the above technical solution, through the provision of the mounting plate and the mounting holes, it is convenient for personnel to fix the fixing box on the top of the warehouse with screws.

[0017] The utility model is further configured as follows: the threaded rod is made of stainless steel.

[0018] By adopting the above technical solution, the threaded rod has the characteristics of high strength, low density and excellent corrosion resistance.

[0019] In summary, the utility model has the following beneficial effects:

[0020] 1. The utility model starts the first motor to lower the hammer and separate it from the shell during cleaning. After the hammer is lowered, the second motor is started. After starting, the second motor drives the fan blades to rotate. When the fan blades rotate, they push the outside air into the shell through the filtration of the dustproof net. The air pushed into the shell will be blown out from the opening below the shell along with the dust. The utility model has an internal cleaning function, which can facilitate the downward discharge of dust inside the shell, thereby ensuring the accuracy of the material level measurement of the structure.

[0021] 2. The utility model starts the third motor, which will drive the threaded rod to rotate after starting. When the threaded rod rotates, it will drive the threaded plate to move upward through the cooperation of the slide rail and the slider. When the threaded plate moves upward, it will drive the shell to move upward together. It can have a lifting function, is simple and labor-saving to operate, reduces the workload of personnel, and is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS
