Description

TECHNICAL FIELD

[0001] The utility model relates to a circular stock bin, especially to a multi-bin shared circular stock bin cleaning equipment, and belongs to the technical field of cleaning equipment. BACKGROUND

[0002] As an efficient material storage facility, the shallow circular stock bin is widely used in the grain, chemical, building material and other industries. Since 2021, the national CNG and CSG have built about 7000 circular stock bins, which can store more than 40 million tons of raw grain. However, there is no any unloading and cleaning equipment in these circular stock bins, and the material is mainly unloaded through the four self-flowing ports on the wall. When the material is lower than the self-flowing port, the material can only be sent out of the bin by manually operating the excavator and cooperating with the grain suction machine, and finally the cleaning is completed by manual cleaning. This traditional method not only consumes a lot of manpower and material resources, but also has high cost. Moreover, due to the lack of automatic equipment, the unloading and cleaning process is inefficient and time-consuming. In addition, there are safety risks such as oxygen deficiency, poisoning and mechanical injury in the operation of personnel in the bin.

[0003] The utility model patent with the application number CN202022828091.1 discloses a mobile spiral cleaning machine, which realizes the transfer and sharing among multiple bins, but still needs to set a channel at the bottom of the bin and bury the conveying equipment. The cleaning machine needs to push the material to the discharge port and send it out through the conveying equipment in the channel. This cannot solve the problem of low frequency of use and difficult maintenance of the conveying equipment. On the other hand, before entering the bin, the cleaning machine needs to manually clean a certain width of the channel as the entrance and exit channel and installation operation surface, which cannot completely avoid the risks brought by manual operation.

[0044] In the following description of the utility model, the terms "upper", "lower", "front", "rear", "left", "right", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are merely for the convenience of describing the utility model and simplifying the description, and do not mean that the device must have a particular orientation.

[0045] In order to make the technical means, creative features, purposes and effects achieved by the utility model easy to understand, the utility model is further described below in combination with specific drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all.

[0046] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the utility model belongs. The terms used in the specification of the utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the utility model.

[0047] As Figures 1 to 11 shown, the multi-bin shared round bin cleaning equipment of the utility model includes a mobile cleaning machine 2, a support adjusting assembly 5, a material conveying auger 8 and a walking mechanism 7, the bottom peripheral wall of the round bin 1 is usually symmetrically provided with four self-flowing discharge ports 1a, each self-flowing discharge port 1a is a certain height away from the ground, and the bottom of the round bin 1 is further provided with a round bin door 1b.

[0048] The mobile cleaning machine 2 extends along the full diameter of the round bin 1, and the two ends of the mobile cleaning machine 2 are respectively supported on the inner wall of the round bin 1 through end head rollers. A material collecting hopper 3 is installed in the middle of the mobile cleaning machine 2, and the front and rear ends of the material collecting hopper 3 are respectively provided with sharp parts for facilitating insertion into the material; a grain suction port fixing seat 3a is arranged at the top of the material collecting hopper 3 for fixing the suction pipe of the grain suction machine outside the bin.

[0049] One end of the mobile cleaning machine 2 is fixed with a driving side driving component 6, and the other end is fixed with a driven side driving component 4. The driving side driving component 6 includes an auger driving speed reducer 6b driven by an auger driving motor 6a, and the auger driving speed reducer 6b is connected to the head end of the corresponding material conveying auger 8 through a driving connecting universal joint 6c respectively.

[0050] The front and rear sides of the driving side driving component 6 are respectively provided with driving side small augers 6d driven by the auger driving speed reducer 6b; the front and rear sides of the driven side driving component 4 are respectively provided with driven side small augers 4b driven thereby, and the input shaft of the driven side driving component 4 is connected to the tail end of the corresponding material conveying auger through a driven side connecting flange 4a respectively.

[0051] Multiple support adjustment components 5 are fixed along the length of the mobile clearing machine 2. Each support adjustment component 5 includes a support caster 5c supported on the ground, which is used to support the mobile clearing machine 2 and adjust its height.

[0052] 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 2. 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.

[0053] 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.

[0054] Furthermore, outwardly extending support adjustment components 5 can be installed in pairs at both ends of the mobile clearing machine 2. The support casters 5c of the support adjustment components 5 serve as end rollers supporting the inner wall of the round hopper 1.

[0055] The mobile cleaning machine 2 has a fixed walking mechanism 7 at its bottom. The walking mechanisms 7 are centrally symmetrically located on both sides of the material collection hopper 3. The two sets of walking mechanisms 7 move in opposite directions and together drive the mobile cleaning machine 2 to rotate around the axis of the circular hopper. 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 in the middle of the walking drive shaft 7c.

[0056] 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. Wear-resistant plates 7d3 are fixed to the vertical side of each angle steel 7d2 by bolts. The outer edge of each wear-resistant plate 7d3 extends beyond the outer diameter of the hub. The support points of the vertical side of each angle steel 7d2 are embedded in the radial groove of the hub and welded together.

[0057] The mobile cleaning machine 2 is equipped with conveying augers 8 on its front and rear sides, including a positive spiral conveying auger 8a and a negative spiral conveying auger 8b, which feed materials into the material collection hopper 3 respectively.

[0058] The mobile clearing machine 2 is equipped with center-of-gravity adjustment support wheels 9 on the front and rear sides, which extend forward or backward and are supported on the ground to prevent the mobile clearing machine from tipping over.

[0059] During installation, the mobile cleaning machine 2 is placed on a flatbed truck. The material flows out of the silo 1 through the gravity discharge port 1a. When cleaning is required, the mobile cleaning machine 2 is pushed into the silo 1 through the silo gate 1b. The mobile cleaning machine 2 is supported on the ground by the support casters 5c fixed to the support adjustment assembly 5. After the mobile cleaning machine 2 is in place, the end rollers at both ends abut against the inner wall of the silo 1.

[0060] Turn on the auger drive motor 6a on the drive side drive component 6, and drive the conveying auger 8 directly through the auger drive reducer 6b and the drive connection universal joint 6c. The positive spiral conveying auger 8a and the negative spiral conveying auger 8b respectively convey the material into the material collection hopper 3, and the suction pipe of the grain suction machine outside the hopper sucks the material in the material collection hopper 3 out of the hopper.

[0061] When the sensor detects that there is no material around the material conveying auger 8, the traveling mechanism 7 drives the traveling wheels 7d to rotate, pushing the mobile cleaning machine 2 to rotate around the central axis of the silo 1. Due to the reaction force of the inner wall of the silo 1 on the end rollers, driven by the traveling wheels 7d, the mobile cleaning machine 2 rotates 360° around the central axis of the silo 1, thereby achieving all-round cleaning.

[0062] The auger drives the reducer 6b and also drives the small auger 6d on the drive side to rotate through the transmission mechanism, conveying the material near the circular silo wall to the end of the positive spiral conveying auger 8a; while the conveying auger 8 is working, it drives the small auger 4b on the driven side to rotate through the gear inside the driven side drive component 4, similarly conveying the material near the circular silo wall to the end of the negative spiral conveying auger 8b; thus cleaning the material on the inner wall of the circular silo 1, reducing the resistance to rotation and avoiding the influence of ground material on the support caster 5c on the ground.

[0063] The mobile sump cleaning machine 2 is equipped with a dual-auger configuration, with conveying augers 8 located on the front and rear sides of the forward direction, respectively, on the front and rear sides of the central traveling mechanism 7. During the cleaning process, if the caking material collapses and buries the equipment, causing the front auger to malfunction or fail to start under load, the rear auger can clear the material behind the equipment. This allows the equipment to unload the load on the front auger by reversing, restoring the front auger to its working state, thus greatly improving the cleaning efficiency.
