Description

Technical Field

[0001] The utility model relates to the technical field of material storage, in particular to a dry material storage bin. Background Art

[0002] Cement is an aggregate composed of numerous small particles, and their common characteristics are: it has many discontinuous surfaces, a large specific surface area, and is composed of many small particles. Powder storage silos are mainly used to store and transport powdered materials, which facilitates the management and use of materials.

[0003] For example, Chinese patent application CN219905194U discloses a material storage bin, which records: by arranging a storage box, supporting legs, a material discharge plate, a baffle, a cross plate, an empty slot, a limit rod, a connecting plate, a push plate, a threaded column and a hand plate, the push plate is convenient for preventing the residual material inside the storage box from piling up, thereby facilitating the pushing out of cement to prevent piling up, making it convenient for the storage box to be better used, thereby increasing the ease of use of the device, and avoiding the accumulation of cement inside the storage box when discharging, which requires people to manually push out the cement inside the storage box, resulting in a waste of a large amount of manpower and material resources, thereby reducing the ease of use of the device.

[0004] When the above-mentioned material storage bin is in use, the staff drives the threaded column to rotate by turning the hand wheel, controls the push plate to slide in the storage box, and pushes the cement to be discharged from the discharge plate. Continuous and automatic operation cannot be achieved, and there are problems such as limited operating accuracy and difficulty in maintaining the required amount of material each time, which affects the efficiency of transportation. In addition, when the cement is discharged into the loading equipment through the discharge plate, after the cement hits the loading equipment, the particles are affected by the airflow and are easily driven by the air and dispersed, causing dust, which has a negative impact on the working environment and the health of operators, and causes waste of resources and environmental pollution. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] In view of the deficiencies in the prior art, the utility model provides a dry material storage bin with the advantages of quantitative unloading, etc., which solves the problem that the staff cannot accurately control the amount of material required for each unloading and a large amount of dust is generated during the cement unloading process.

[0007] (II) Technical solution

[0008] To achieve the above, not only the problem of staff being unable to accurately control the amount of material required for each unloading is solved, but also the purpose of reducing cement waste is ensured. The utility model provides the following technical solutions: a dry material storage bin, comprising a storage box, a quantitative dust-proof mechanism is installed on one side of the storage box, the quantitative dust-proof mechanism comprises a slidable lifting plate, the upper surface of the lifting plate is connected to a rack plate, one side of the rack plate is engaged with an intermittently driven driving gear, the upper surface of the lifting plate is connected to a sliding column, a spring is sleeved on the sliding column, and a sleeve is slidably connected to one end of the sliding column.

[0009] As a preferred solution of the dry material storage bin of the utility model, one end of the sleeve away from the spring is connected to a limiting frame, a mounting plate is arranged below the limiting frame, and the lifting plate is slidably connected in the mounting plate.

[0010] As a preferred solution of the dry material storage bin of the utility model, a feed plate is connected between the storage box and the mounting plate, a support frame is connected to the feed plate, and a motor is installed on the support frame.

[0011] As a preferred solution of the dry material storage bin of the utility model, a side of the mounting plate away from the unloading plate is connected to a corrugated dust cover, and an end of the corrugated dust cover away from the mounting plate is connected to a slide frame.

[0012] As a preferred solution of the dry material storage bin of the utility model, a slider frame is slidably connected in the slide slot frame, and a handle is connected to one side of the slider frame.

[0013] As a preferred solution of the dry material storage bin of the utility model, the lower surface of the slider frame is connected to a loading box, an observation window is embedded in one side of the loading box, and the lower surface of the loading box is connected to a universal wheel.

[0014] Compared with the known prior art, the technical solution provided by the utility model has the following beneficial effects:

[0015] 1. The output end of the motor on the support frame drives the driving gear to rotate counterclockwise, and the driving gear rotates to intermittently mesh with the rack plate on one side, driving the lifting plate under the rack plate to move upward. When the teeth on the driving gear do not mesh with the rack plate on one side, the compressed springs on both sides will push the lifting plate to move downward quickly under the reaction force. The lifting plate slides in the mounting plate to control the intermittent unloading of the unloading plate. Intermittent control can adjust the unloading amount and frequency according to production needs, and can achieve precise control of the unloading amount, avoid excessive or insufficient unloading, and make the production line run more smoothly;

[0016] 2. The staff pushes the handle to make the slider frame slide smoothly into the slide frame. By connecting a closed corrugated dust cover between the unloading plate and the loading box, during the cement unloading process, cement is transported through the sealed corrugated dust cover, which can not only effectively reduce the flying of cement dust in the air and keep the working environment clean, but also reduce the loss of cement during transportation, reduce costs and improve production efficiency.

[0027] One end of the sleeve 206 away from the spring 205 is connected to the limiting frame 207, and the lifting plate 201 is slidably connected in the mounting plate 208. A mounting plate 208 is arranged below the limiting frame 207. The lifting plate 201 slides in the mounting plate 208, thereby controlling the intermittent unloading of the unloading plate 209.

[0028] A blanking plate 209 is connected between the storage box 100 and the mounting plate 208, and a support frame 210 is connected to the blanking plate 209. A motor 211 is installed on the support frame 210, and the driving gear 203 is driven to rotate counterclockwise through the output end of the motor 211 on the support frame 210.

[0029] During use, the output end of the motor 211 on the support frame 210 drives the driving gear 203 to rotate counterclockwise, and the driving gear 203 rotates to intermittently engage with the rack plate 202 on one side, driving the lifting plate 201 below the rack plate 202 to move upward. When the teeth on the driving gear 203 do not engage with the rack plate 202 on one side, the springs 205 compressed on both sides will push the lifting plate 201 to move downward quickly under the reaction force, and the lifting plate 201 slides in the mounting plate 208 to control the intermittent unloading of the unloading plate 209. The intermittent control can adjust the unloading amount and frequency according to production needs, and can achieve precise control of the unloading amount, avoid excessive or insufficient unloading, and make the production line run more smoothly.
