Abstract
Description
Technical Field
[0001] This utility model relates to the field of warehouse clearing machine technology, specifically to a multi-angle warehouse clearing machine. Background Technology
[0002] A silo cleaning machine is a specialized piece of equipment used to clean residual materials inside silos, tanks, or storage containers. It primarily addresses issues such as material accumulation, caking, and blockages, ensuring continuous production and efficient storage. Its core functions are as follows: Highly efficient removal of residual materials: Through rotating arms, vibration devices, or airflow assistance, the cleaning machine can quickly crush and remove caking materials (such as cement, fly ash, and grain) from the silo, avoiding the safety hazards of manual cleaning and improving operational efficiency; Prevention of blockages and bridging: Long-term storage of materials can lead to bridging or adhesion to the walls. The cleaning machine can loosen the accumulated layers in real time, ensuring smooth material flow and reducing downtime for maintenance due to blockages; Ensuring production safety: It replaces manual labor in high-risk, confined spaces, reducing the risks of suffocation and collapse, making it particularly suitable for high-risk industries such as chemicals and building materials.
[0003] CN221542758U discloses a multi-angle cement silo cleaning machine. A movable ring is slidably sleeved on one side of the outer wall of a rotating connecting rod. A fixed block is welded to the outer ring of the movable ring. Two fixed blocks are provided, and a steel wire rope is fixedly connected to the bottom of each block. A fixed ring is also fixedly connected to the outer wall of the rotating connecting rod located at the lower end of the movable ring. This invention has the following advantages: The output of a drive motor drives the threaded rod to rotate, allowing for upward or downward pulling of the steel wire rope. The included angle between the bottom ends of the support arms at the connector can be controlled, ensuring that the support arms do not contact the cement at the bottom of the cement silo during operation. Furthermore, when the rotating connecting rod rotates along with the support arms, the support arms do not scrape against the cement, increasing rotational resistance. By controlling the included angle between the two support arms, the distance between the two milling mechanisms can be adjusted, controlling the range of cement milling.
[0004] The problem with the aforementioned multi-angle cement silo cleaning machine is that:
[0005] 1. Exposed regulating mechanism is prone to jamming.
[0006] The system employs an external mechanical linkage structure consisting of a "moving ring + wire rope + threaded rod," with the wire rope and threaded rod exposed to the outside of the rotating connecting rod. In the high-dust environment of a cement silo, materials can easily intrude into the wire rope guide rail and threaded transmission parts, causing the mechanism to jam and malfunction in adjustment. Furthermore, the wire rope is prone to tensile deformation under long-term stress, affecting angular accuracy.
[0007] 2. Inaccurate control of the support arm angle
[0008] Controlling the support arm angle using a single-point traction wire rope presents two problems:
[0009] The elastic deformation of the wire rope causes the support arm angle to spring back, making it difficult to lock the preset position;
[0010] The double support arms are adjusted synchronously by a single steel wire rope, which is prone to uneven force distribution, resulting in asymmetrical angles and poor stability in controlling the milling range. Utility Model Content
[0011] This invention proposes a multi-angle warehouse clearing machine, which solves the problems of easy jamming of the exposed adjustment mechanism and inaccurate control of the angle of the support arm in the prior art.
[0012] The technical solution of this utility model is as follows: A multi-angle warehouse cleaning machine includes a support assembly, the support assembly includes a rotating connecting rod, a drive assembly disposed at the bottom of the rotating connecting rod, the drive assembly includes a worm gear and a worm wheel meshing and rotating inside the rotating connecting rod, and milling assemblies symmetrically arranged on the outer side of the rotating connecting rod, which can rotate and lock with the drive assembly.
[0013] Preferably, the support assembly further includes a rotating connecting sleeve, which is fixedly connected to the top of the rotating connecting rod. The support assembly also includes two sets of sealed bearings, which are symmetrically arranged on the side of the rotating connecting rod, and the outer ring of the sealed bearing is fixedly connected to the rotating connecting rod.
[0014] Preferably, the drive assembly includes a forward and reverse motor, which is fixedly installed inside the rotating connecting rod.
[0015] Preferably, the drive assembly further includes a rotating shaft, which is fixedly connected to the output end of the forward and reverse motors, and the outer side of the rotating shaft is fixedly connected to a worm gear.
[0016] Preferably, the drive assembly further includes a main rotating rod, which is rotatably connected to the inner side of the rotating connecting rod, and the outer side of the main rotating rod is fixedly connected to the worm gear. One end of the main rotating rod is fixedly connected to the inner ring of the sealed bearing.
[0017] Preferably, the drive assembly further includes a secondary rotating rod, which is rotatably connected to the inner side of the rotating connecting rod, and the secondary rotating rod is fixedly connected to the inner ring of the sealed bearing.
[0018] Preferably, the milling assembly includes a geared disc, wherein one set of the geared discs is fixedly connected to the outside of the main rotating rod, and the other set of the geared discs is fixedly connected to the outside of the auxiliary rotating rod.
[0019] Preferably, the milling assembly further includes support arms, one set of which is fixedly connected to the main rotating rod, and the other set of which is fixedly connected to the auxiliary rotating rod. The milling assembly also includes a milling sleeve, which is fixedly connected to the outside of the support arms.
[0020] The beneficial effects of this utility model are as follows:
[0021] I. Improvements to the fully enclosed worm gear drive system: The drive components are completely built into the rotating connecting rod, and the transmission is achieved through the meshing of the worm and worm wheel, while the sealed bearings isolate external dust.
[0022] Advantages: Prevents dust from entering transmission components, eliminating jamming problems compared to one of the disadvantages;
[0023] The self-locking characteristic of the worm gear enables stepless angle adjustment and automatic locking, eliminating the need for an additional braking mechanism.
[0024] II. Dual-gear synchronous reverse adjustment mechanism
[0025] Improvement: The main rotating rod is controlled by a forward and reverse motor via a worm gear;
[0026] The auxiliary rotating rod is linked with the main rotating rod through two sets of meshing gear discs, enabling the two support arms to rotate synchronously in opposite directions.
[0027] Advantages: Rigid gear transmission replaces flexible steel wire rope, eliminating the risk of deformation and ensuring precise angle adjustment compared to defect two; the double support arms symmetrically expand / retract, and the milling sleeve always maintains a balanced operating state, improving the controllability of the cleaning range.

[0035] Please see Figure 1 and Figure 2 and Figure 3 and Figure 4 The present invention provides a technical solution: a multi-angle warehouse cleaning machine, including a support component 1, the support component 1 including a rotating connecting rod 11, a drive component 2 disposed at the bottom of the rotating connecting rod 11, the drive component 2 including a worm gear 221 and a worm wheel 231 meshing and rotating inside the rotating connecting rod 11, and milling components 3 symmetrically arranged on the outside of the rotating connecting rod 11, which can rotate and lock with the drive component 2;
[0036] This design systematically solves the pain points of low adjustment reliability and insufficient precision in existing technologies by integrating the transmission system, replacing flexible traction with rigid meshing, and applying a self-locking mechanism. This significantly improves the adaptability and operating efficiency of the warehouse cleaning machine under harsh working conditions.

[0038] The rotating connecting sleeve 12 can be assembled with an external rotating drive mechanism to drive the entire support component 1 to perform the inventory cleaning process.
[0039] The sealed bearing 13 prevents foreign objects from entering the rotating connecting rod 11.
[0040] Please see Figure 3 and Figure 4 The drive assembly 2 includes a forward and reverse motor 21, which is fixedly installed inside the rotating connecting rod 11.
[0041] The drive assembly 2 also includes a rotating shaft 22, which is fixedly connected to the output end of the forward and reverse motor 21, and the outer side of the rotating shaft 22 is fixedly connected to the worm gear 221.

[0043] The drive assembly 2 also includes a secondary rotating rod 24, which is rotatably connected to the inner side of the rotating connecting rod 11, and the secondary rotating rod 24 is fixedly connected to the inner ring of the sealed bearing 13.
