[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0026] Combination Figures 1-7This utility model discloses a blockage clearing machine, including a frame 1 and a track for guiding the machine. One end of the frame 1 is provided with a brush assembly 2, which is specifically implemented by combining a rotary nylon brush body with a geared motor 21. The other end of the frame 1 is provided with a propeller assembly 3. A battery 4 for powering the blockage clearing machine is provided on the upper surface of the frame 1. The battery 4 is a 72V lithium-ion battery pack. Guide wheels that contact the track are respectively provided on both sides of the frame 1. The guide wheels include a small guide wheel group 7 and a large guide wheel group 8.

[0027] Specifically, the frame 1 adopts an H-shaped steel structure to form the main load-bearing body. The front brush assembly and the rear propeller assembly complement each other in terms of working direction. The built-in battery 4 is centrally located on the upper part of the frame and supplies power to each component through a waterproof junction box. Four sets of guide wheels are placed on both sides of the frame. The wheel structure, cone surface 5, and flat rail 6 form a double constraint. Each functional unit achieves the operation cycle of brushing-crushing-pushing through the timing coordination of the control system.

[0028] In this embodiment, tracks 11 are symmetrically arranged on both sides of the frame 1. The tracks 11 are made of rubber and equipped with anti-slip texture, which enhances the stability of the equipment in contact with the ground and provides a bearing base for the central working component. A crushing roller 12 is arranged on the frame 1 between the tracks 11 and the brush assembly 2. The crushing roller 12 is a rotating crushing component, specifically a metal roller structure with toothed protrusions on the surface, used to pre-crush hard blockages. A bulldozer scraper 13 is arranged on the frame 1 between the tracks 11 and the propeller assembly 3. The two sides of the bulldozer scraper 13 are arc-shaped, matching the working area of ​​the propeller assembly 3. When the bulldozer scraper 13 works, it pushes the blockage to one side.

[0029] Specifically, such as Figure 3As shown, the crushing roller 12 includes a long cylinder 121, a short cylinder 122, a long shaft 123, and a roller frame 124. The long shaft 123 passes through both the long cylinder 121 and the short cylinder 122, and is connected to both cylinders via bearings. The roller frame 124 is located between the long cylinder 121 and the short cylinder 122, and at one end of the long shaft 123. The roller frame 124 is connected to the frame 1. Both the long cylinder 121 and the short cylinder 122 are provided with grooves 1211 for the rubber rods used in the crushing process. These grooves are filled with highly elastic rubber rods or other wear-resistant elastic materials. During the crushing process, these rubber rods not only increase the friction between the rubber rods and the blockages, making them easier to be drawn under the crushing roller, but also act as a buffer, preventing damage to the equipment structure from excessive impact. Simultaneously, the irregular shape of the rubber rod surface also helps to tear and squeeze the blockages, improving crushing efficiency. Since the crushing roller 12 is composed of a long cylinder 121 and a short cylinder 122, which are arranged at intervals on the long shaft 123 to form a discontinuous crushing surface, this structural design allows the crushing roller to adapt to blockages of different sizes and shapes. The long cylinder 121 is responsible for the main crushing operation, while the short cylinder 122 is used to assist in processing edge areas or smaller particles, thereby improving the overall cleaning effect.

[0030] like Figure 4 As shown, the brush assembly 2 includes a geared motor 21, a brush shaft 22, and a brush body 23. The geared motor 21 is connected to the upper surface of the frame 1 via a bracket, forming a high-position power source layout to prevent sewage or debris from the working surface from entering the motor. The output end of the geared motor 21 is connected to the brush shaft 22, which is fixed to the side wall at the end of the frame 1 via a bearing 221. The lower end of the brush shaft 22 is connected to the brush body 23. The output shaft of the geared motor 21 is directly connected to the top end of the brush shaft 22 via a rigid coupling, eliminating the intermediate transmission link of belt or chain and ensuring the straightness and stability of the power transmission path. The bearing 221 forms a radial constraint on the brush shaft 22 through double-row ball bearings. During the continuous rotation of the brush shaft 22, the brush body 23 sweeps away the blockage with a spiral trajectory and throws the debris away from the working area by centrifugal force.

[0031] refer to Figure 5The propeller assembly 3 includes a brushless motor 31, a small pulley 32, an A-belt 33, a large pulley 34, a propeller shaft 35, and a propeller body 36. The brushless motor 31 is fixed to the upper surface of the frame 1 by a bracket. The brushless motor 31 is a DC 72V 1500 RPM brushless motor 31, 1.5kw, controlled by a remote control. The propeller assembly 3 has two sets. One of the brushless motors 31 is mounted at a 30° angle to the side wall of the frame 1. The output end of the brushless motor 31 is connected to the central shaft of the small pulley 32. The upper end of the propeller shaft 35 is connected to the large pulley 34. The propeller shaft 35 is fixed to the side wall of the end of the frame 1 by a bearing 221. The lower end of the propeller shaft 35 is connected to the propeller body 36. The small pulley 32 and the large pulley 34 are connected by an A-belt 33. The A-belt 33 is connected between the small pulley 32 and the large pulley 34 to transmit torque.

[0032] Specifically, when the brushless motor 31 drives the small pulley 32 to rotate, the power is transmitted to the large pulley 34 through the A-shaped V-belt 33, which drives the propeller shaft 35 and the propeller body 36 to generate a pushing force. The radial constraint of the belt bearing 221 on the propeller shaft 35 can offset the lateral vibration when the equipment moves along the track, while the elastic buffering characteristics of the belt drive can absorb the impact load during the motor start-up and shutdown phase. The reduction ratio design of the large pulley 34 and the small pulley 32 allows the propeller body 36 to reduce the speed while maintaining high torque output, avoiding the splashing of blockages due to high-speed rotation. The propeller assembly 3 and the brush assembly 2 work together in a coordinated manner, and the crushed material is continuously pushed forward by the propeller blades to prevent it from accumulating under the frame 1.

[0033] The track includes a conical track 5 and a flat track 6. Specifically, the conical track 5 is fixed to the wall, and the small guide wheel assembly 7 engages with the conical track 5 through grooves, preventing the unblocking machine from detaching from the track when moving on the wall. The flat track 6 is installed on the ground, and its horizontal extension direction contacts the cylindrical wheel sidewall of the large guide wheel assembly 8, ensuring that the unblocking machine travels in a straight line when moving on the ground. The small guide wheel assembly 7 continuously restricts vertical displacement, and the large guide wheel assembly 8 provides horizontal constraint. The complementary cooperation of the two avoids derailment caused by uneven force at the junction of the single track structure.

[0034] The small guide wheel assembly 7 includes a first mounting frame 71 and a grooved guide wheel 72. Specifically, the first mounting frame 71 is fixed to the side wall of the frame 1 by bolts. The grooved guide wheel 72 is symmetrically installed at both ends of the first mounting frame 71. Its conical groove forms an engaging contact with the conical track 5 on the wall. When the unblocking machine passes the junction of the wall and the ground, the conical groove of the grooved guide wheel 72 and the inclined surface of the track generate geometric constraints, limiting the longitudinal displacement of the guide wheel. The depth of the conical groove matches the inclination angle of the inclined surface of the conical track 5, ensuring that the grooved guide wheel 72 maintains an effective contact area under different turning angles.

[0035] The large guide wheel assembly 8 includes a second mounting frame 81 and general guide wheels 82. The second mounting frame 81 is connected to the side wall of the frame 1 by bolts to form a rigid support. When the unblocking machine moves along the flat rail 6, the side walls of the general guide wheels 82 at both ends of the second mounting frame 81 form surface contact with the side walls of the flat rail 6. Since the two general guide wheels 82 are located on the same second mounting frame 81, when the flat rail 6 undergoes local deformation, the second mounting frame 81 can constrain the guide wheels 82 to shift synchronously, avoiding the risk of derailment caused by the guide wheels on one side losing contact.

[0036] Working process: After the unblocking machine is started via remote control, battery 4 provides the necessary power to the geared motor 21, brushless motor 31, and control system. The unblocking machine moves along the conical track 5 and flat rail 6 arranged on the wall. The grooved guide wheel 72 in the small guide wheel group 7 engages with the conical track 5, and the column guide wheel 82 in the large guide wheel group 8 fits against the side wall of the flat rail 6. The double guide structure ensures stable operation of the equipment and prevents derailment. The geared motor 21 drives the brush shaft 22 to rotate, which in turn drives the brush body 23 to rotate at high speed. The brush rotation path is spiral, and combined with centrifugal force, it throws the debris to both sides away from the working area, breaking up the debris. The crushing roller 12 rolls forward to further crush and grind large, hard materials that were not fully processed by the brush, making them easier to handle and clean up later. The propeller assembly 3 is driven by a brushless motor 31, which drives the propeller body 36 to rotate at low speed and high torque through an A-belt transmission system 33, generating a stable forward thrust. The propeller not only propels itself forward but also helps to concentrate and push the material processed by the brush and crushing roller forward, avoiding accumulation under the equipment and secondary blockage. The bulldozer scraper 13 uses its arc-shaped structure to further concentrate the material pushed forward and scrape it to both sides, restoring the passage to a smooth state.
