TECHNICAL FIELD
[0001] The utility model relates to grain silo technical field especially relates to a kind of electromagnetic adsorption type silo inner wall fixing device. BACKGROUND
[0002] In recent years, China's total grain output steadily increases, to cope with the growth of grain market demand, the state further increases support for large-scale grain silo construction, especially in the main grain producing areas and logistics hub areas, at the same time, encourage enterprises to adopt intelligent, green silo technology, improve the level of science and technology of grain storage, under the guidance of national policy, China's grain industry is developing towards efficient and stable, and large-scale grain silo as a key infrastructure will play an irreplaceable role in ensuring food security and improving market efficiency.
[0003] During the grain storage process, due to the angle between the inner wall and the cone bottom, there is often some accumulated grain, which will cause mold if not cleaned for a long time. The mold not only wastes the grain itself but also damages other grains. However, it is very difficult to clean this part of the grain. The traditional cleaning method usually requires manual entry into the silo, which has safety hazards and low efficiency. The existing cleaning equipment cannot adapt to the special structure of the cone bottom silo and cannot effectively clean the residual grain between the inner wall and the cone bottom.
[0004] When grain is stored in the silo, due to the gravity accumulation of long-term storage and the certain humidity and viscosity of the grain itself, grain accumulation will occur at the angle between the inner wall and the cone bottom when the grain is discharged. If not cleaned for a long time, it will cause mold and insect damage, which not only wastes grain but also damages other normal grain. It is very difficult to clean the grain at this point. Using a long rod to clean can only clean the entrance and its surrounding area, as the length of the long rod is limited, it cannot clean deeper places. The existing mechanical cleaning device cannot be fixed and cleaned because the entrance is small and the inner wall of the silo is a circular arc structure, and the bottom of the silo is a cone bottom instead of a flat bottom. Manual cleaning is difficult because the cone bottom of the cone bottom silo has a certain slope and there is no device that can stand stable between the inner wall of the cone bottom silo.

DETAILED DESCRIPTION
[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0026] With reference to Figure 1 , Figure 2 and Figure 3 , an embodiment provided by the utility model is as follows: an electromagnetic adsorption type silo inner wall fixing device, comprising an arc electromagnet 100, a fixing device shell 200 is installed on the front side of the arc electromagnet 100, an electric quantity display 600 is installed on the front side middle part of the fixing device shell 200, aluminum alloy handles 400 are installed on the front side left and right sides of the fixing device shell 200, an inner bright light type switch 500 is installed on the front side middle upper part of the fixing device shell 200, and a fixing device battery 300 is installed on the front side top of the fixing device shell 200; a magnetically conductive fastening panel 110 is installed on the back side of the arc electromagnet 100, an electromagnet shell 140 is arranged on the outer side of the arc electromagnet 100, a red copper coil 130 is installed on the inner side of the electromagnet shell 140, and fastening screws 120 are installed on the outer side of the magnetically conductive fastening panel 110 at both ends; the arc electromagnet 100 mainly comprises the magnetically conductive fastening panel 110, the fastening screw 120, the red copper coil 130 and the electromagnet shell 140;
[0027] Specifically, the working voltage of the circular arc electromagnet 100 is 24V, the rated power is 16W, and the resistance is 36Ω±10%. When the coil is energized, it generates a magnetic field that attracts the electromagnet to the inner wall of the silo. The inner wall of the silo is circular arc-shaped, and the circular arc electromagnet 100 fits perfectly against the arc of the silo, generating a magnetic force that attracts the entire device to the inner wall.
[0028] Reference Figure 1 , Figure 2 and Figure 3 The mounting housing 200 is made of 0.5mm thick stainless steel, ensuring structural strength and reducing weight while providing wear resistance and corrosion resistance to protect internal components and adapt to the complex environment inside the silo. The aluminum alloy handle 400 is also made of aluminum alloy, ensuring strength while reducing weight. When the internal coil of the arc electromagnet 100 is energized, a magnetic field is generated. This magnetic field forms a strong magnetic force through the magnetically conductive panel. When the silo sidewall contacts the surface of the arc electromagnet 100, the magnetic force forms a closed magnetic circuit through the silo sidewall, thus generating a continuous attraction force. When the coil is de-energized, the magnetic field disappears, and the magnetic force also disappears, allowing the electromagnetic adsorption silo inner wall mounting device to be removed from the silo sidewall. This process achieves precise control of the on / off state of the electromagnetic adsorption silo inner wall mounting device, producing instantaneous adsorption and release.
[0029] Specifically, each side of the fixing device is equipped with an aluminum alloy handle 400, which makes it easy for operators to hold, tie rope hooks, and move the fixing device.

[0031] Specifically, the 500 internal light switch has an internal light that illuminates when turned on, improving visibility in the dark environment inside the silo and controlling the opening and closing of the electromagnet. It is simple and convenient to operate.

[0033] The cleaning staff can drag and support with two electromagnetic adsorption type silo inner wall fixing devices as fulcrums, hold the cleaning tool, clean the accumulated grain between the inner wall and the cone bottom of the grain cone-bottom silo, after cleaning the current position without accumulated grain, the cleaning staff can first move one electromagnetic adsorption type silo inner wall fixing device on the sidewall of the silo to the inside of the sidewall of the silo, move a certain distance, then turn on the switch to continue power supply and perform strong adsorption, then move another electromagnetic adsorption type silo inner wall fixing device, move a certain distance, and then clean the accumulated grain between the inner wall and the cone bottom of the grain cone-bottom silo, so that one electromagnetic adsorption type silo inner wall fixing device is moved first, then another electromagnetic adsorption type silo inner wall fixing device is moved, and then the two electromagnetic adsorption type silo inner wall fixing devices are used as fulcrums to drag and support, and the accumulated grain between the inner wall and the cone bottom of the grain cone-bottom silo is cleaned.
