[0002] Shallow circular silos, as a highly efficient material storage facility, are widely used in industries such as grain, chemicals, and building materials. Since 2021, COFCO and China Grain Reserves Corporation have built approximately 7,000 shallow circular silos, storing a total of over 40 million tons of raw grain. However, these silos lack any unloading or cleaning equipment, relying primarily on four gravity-flow inlets on the silo walls for material removal. When the material level falls below the gravity-flow inlets, the material must be manually removed from the silo using excavators and suction machines, followed by manual cleaning. This traditional method not only consumes significant manpower and resources, resulting in high costs, but also leads to inefficiency and prolonged processing times due to the lack of automation. Furthermore, personnel working inside the silos face safety risks such as oxygen deficiency, poisoning, and mechanical injury. Utility Model Content

[0044] like Figures 1 to 10 As shown, in the shallow circular silo mobile cleaning device of this utility model, the bottom perimeter of the shallow circular silo 1 is usually symmetrically provided with four self-flowing discharge ports 1a, each discharge port 1a is at a certain height from the ground, and the bottom of the shallow circular silo 1 is also provided with a shallow circular silo door 1b.

[0045] A central seat 2 is fixed at the center of the ground of the shallow circular silo 1. A central cylinder 2a that is raised upward is connected to the center of the central seat 2. A grain suction port fixing seat 2b is provided at the center of the upper end of the central cylinder 2a for fixing the suction pipe of the grain suction machine outside the silo.

[0046] The mobile cleaning machine 4 extends radially along the shallow circular silo 1, with one end fixed to the central seat 2 and the other end close to the inner wall of the shallow circular silo 1. Multiple support adjustment components 5 are fixed along the length of the mobile cleaning machine 4. Each support adjustment component 5 includes a support caster 5c supported on the ground, used to support the mobile cleaning machine 4 and adjust its height.

[0047] The upper part of the support adjustment assembly 5 is provided with a support housing 5a. The side wall of the support housing 5a is welded with a housing connection flange 5k for connection with the mobile cleaning machine 4. The upper end of the support housing 5a is provided with a housing top cover 5g. A pressure cap 5h is screwed into the inner thread of the housing top cover 5g. A support spring 5e is provided below the pressure cap 5h. The lower end of the support spring 5e is provided with a telescopic adjustment seat 5d. An axially positioned and rotatable telescopic adjustment screw 5f is inserted into the center hole of the pressure cap 5h. The lower end of the telescopic adjustment screw 5f is screwed into the center threaded hole of the telescopic adjustment seat 5d. A square tube 5b is welded to the lower end of the telescopic adjustment seat 5d. The square tube 5b extends from the lower port of the support housing 5a and a support caster wheel 5c is installed at the lower end. The support spring 5e can provide a certain support force and can also pass through hard obstacles with elasticity during movement.

[0048] The telescopic adjusting screw 5f can be used to adjust the position of the telescopic adjusting seat 5d via the adjusting handle 5j. The adjusting handle 5j is L-shaped, with its short side inserted into the upper end of the telescopic adjusting screw 5f and its long side extending downwards. By rotating the long arm of the adjusting handle 5j to a horizontal position, the telescopic adjusting screw 5f can be rotated via the adjusting handle 5j, causing the telescopic adjusting seat 5d to raise or lower the square tube 5b and the support caster 5c, thereby adjusting the height of the entire support adjusting assembly 5 to adapt to different ground conditions.

[0049] The rotary mechanism includes a triangular star-shaped support 3 located in the central cylinder 2a. The outer ends of the triangular star-shaped support 3 are respectively equipped with central positioning wheels 3a, and each central positioning wheel 3a is supported on the inner wall of the central cylinder 2a. The outer end of the mobile cleaning machine 4 is supported on the inner wall of the shallow circular silo 1 through the end directional wheel 8.

[0050] The front side of the mobile silo cleaning machine 4 is fixed with a material conveying auger 6, which is driven by the auger drive motor 6a. The discharge end of the material conveying auger 6 is connected to the central cylinder 2a, which sends the material at the bottom of the shallow circular silo 1 into the central cylinder 2a.

[0051] The mobile warehouse clearing machine 4 is fixed to the rear side with a walking mechanism 7. The walking mechanism 7 includes a walking motor 7a, a walking reducer 7b, a walking drive shaft 7c, and walking wheels 7d. The rotor shaft of the walking motor 7a is connected to the input end of the walking reducer 7b, and the output end of the walking reducer 7b is connected to the walking drive shaft 7c. Walking wheels 7d are installed at both ends and the middle part of the walking drive shaft 7c.

[0052] The traveling wheel 7d includes at least three hubs. The circumference of each hub is connected as a whole by evenly distributed angle steel 7d2.

The support points of the vertical side of each angle steel 7d2 are embedded in the radial groove of the hub and welded together.

[0053] During installation, the mobile cleaning machine 4 is placed on a flatbed truck. The material flows out of the shallow circular silo 1 through the gravity discharge port 1a. When cleaning is required, the mobile cleaning machine 4 is pushed into the shallow circular silo 1 through the shallow circular silo door 1b. The center seat 2 is fixed to the center of the shallow circular silo 1 with expansion bolts. The mobile cleaning machine 4 is supported on the ground by the support casters 5c fixed on the support adjustment assembly 5. After the mobile cleaning machine 4 is in place, the center positioning wheel 3a is fixed on the inner ring of the center seat 2 to form a center rotation structure. The end directional wheel 8 is pressed against the inner wall of the shallow circular silo 1. At this time, the entire mobile cleaning machine 4 is in a fixed position.

[0054] Turn on the auger drive motor 6a to drive the material conveying auger 6 through chain transmission to transport the material into the center seat 2. The suction pipe of the grain suction machine outside the warehouse is fixed on the grain suction port fixed seat 2b to suck the material in the center seat 2 out of the warehouse.

[0055] When the sensor detects that there is no material around the material conveying auger 6, the traveling mechanism 7 drives the traveling wheels 7d to rotate, pushing the mobile cleaning machine 4 to rotate around the central axis of the center seat 2 and the shallow circular silo 1. Due to the reaction force of the end directional wheel 8 and the center positioning wheel 3a, driven by the traveling wheels 7d, the mobile cleaning machine 4 rotates 360° around the shallow circular silo 1 with the center seat 2 as the center, thereby achieving all-round cleaning.
