[0001] This utility model relates to the field of material conveying technology, specifically to a tracked automatic loading machine. Background Technology

[0002] In today's coal transportation industry, the efficiency and safety of loading operations are key factors affecting logistics costs and worker safety. At large coal yards, coal loading currently relies primarily on traditional loaders. However, existing coal loaders often have some significant shortcomings.

[0003] Traditional loaders are mostly stationary or semi-mobile, which makes them unsatisfactory in terms of loading efficiency and mobility. In actual operation, different types of trucks, such as semi-trailers, dump trucks, and container trucks, have different cargo box specifications. Faced with these differentiated cargo boxes, existing loaders lack a loading strategy that can quickly adapt. For example, in terms of height adjustment, traditional hydraulic lifting mechanisms are relatively slow in response, typically requiring 2-3 minutes to complete a full-stroke adjustment. Moreover, it is difficult to correct the height in real time during equipment movement, resulting in the inability to accurately load coal into cargo boxes with different height requirements, thus affecting loading efficiency. To solve the above problems, we propose a tracked automatic loader. Utility Model Content

[0018] 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.

[0019] Please see Figure 1-3 This utility model provides a technical solution for a tracked automatic loading machine, including a frame 100, which serves as the main support structure of the entire loading machine, providing a stable installation foundation for other components. The bottom of the frame 100 is equipped with a tracked walking unit 1, which gives the loading machine mobility and good terrain adaptability. The tracked structure can significantly distribute the pressure of the equipment on the ground, allowing stable travel on soft coal yard surfaces or complex road surfaces with potholes and varying slopes. Driven by a motor, the track can easily move between vehicles in different locations, quickly reaching the loading point, greatly improving operational mobility. Furthermore, its small turning radius allows for flexible adjustment of the operating direction, further adapting to various site conditions and loading needs.

[0020] The upper end of the frame 100 is equipped with a lifting conveyor belt 3 and a adjusting conveyor belt 4. The main function of the lifting conveyor belt 3 is to lift the coal from the feeding unit 2 to a certain height to meet the needs of subsequent loading. The function of the adjusting conveyor belt 4 is to further adjust the position and increase the height of the coal conveyed by the lifting conveyor belt 3, so that the coal is accurately delivered to the required position in the truck bed 15 of different heights.

[0021] The adjusting conveyor belt 4 is located directly below the discharge port of the lifting conveyor belt 3, ensuring that the coal on the lifting conveyor belt 3 can accurately fall onto the adjusting conveyor belt 4 and then into the cargo box 15 of the waiting truck, thus achieving efficient and precise loading operations.

[0022] The feed end of the elevator belt conveyor 3 is equipped with a feeding unit 2, which can effectively collect coal from the coal yard and transport it to the elevator belt conveyor 3.

[0023] A telescopic unit is provided between the adjusting belt conveyor 4 and the frame 100 to control the position of the discharge port of the adjusting belt conveyor 4. The telescopic unit is used to control the position of the discharge port of the adjusting belt conveyor 4, which is a key component to ensure that it can adapt to the differences in the carriages of different vehicle models.

[0024] When faced with different types of wagons, it can precisely adjust the height and horizontal position of the discharge port in a short time, overcoming the slow response and inability to correct in real time issues of traditional equipment in height adjustment. Through this flexible adjustment, the loader can accurately load coal into wagons of different sizes and heights, greatly improving its adaptability to various vehicle types and loading efficiency.

[0025] Before closing the electrical control cabinet 7, a detailed inspection is performed to ensure there are no problems. Then, the main air switch is closed, followed by closing all circuit breakers in sequence. On the control panel 11 in the cab 9, the emergency stop button is activated, and the control power switch is turned on. The hydraulic system 8 is then checked, and after ensuring there are no problems, the main oil pump 12 start button is pressed. The hydraulic control valve can only be operated after the motor has fully started to allow the equipment to move. The hydraulic valve control lever 10 is manually operated (or the foot pedal is used) to move the equipment to the loading machine's working position. Next, the adjusting belt conveyor 4 is started, and after it is fully started, the lifting belt conveyor 3 is started. The feeding unit 2 is started under the same operation to collect coal from the coal yard and transport it at a stable speed to the lifting belt conveyor 3. The high-speed belt lifts the coal from a low position to a higher position and it falls onto the adjusting belt conveyor 4, which then transports the coal into the truck bed 15. The entire process minimizes manual intervention and improves loading efficiency and accuracy.

[0026] The lifting belt conveyor 3 and the adjusting belt conveyor 4 are controlled by two different motor reducers 19.

[0027] The tracked walking unit 1 moves by the main oil pump 12 driven by the motor generating high-pressure power oil, which in turn drives the hydraulic motor 20 to generate power and drive the tracked machine to move.

[0028] Specifically, the telescopic unit is a core component that ensures the loading machine adapts to the differences in the carriages of different car models. Its function is to control the height and position of the discharge port of the adjusting belt conveyor 4. The telescopic unit includes a telescopic frame 17 and a telescopic cylinder 16. The telescopic frame 17 is fixed to the upper end of the frame 100, and the adjusting belt conveyor 4 is connected to the free end of the telescopic frame 17 so as to adjust its position by following the telescopic movement of the telescopic frame 17.

[0029] The telescopic cylinder 16 is fixed at the fixed end of the telescopic frame 17. The output end of the telescopic cylinder 16 is connected to the adjusting belt conveyor 4. Through the telescopic power of the telescopic cylinder 16, the free end of the telescopic frame 17 is precisely pushed to telescopically move, which can change the unloading position of the adjusting belt conveyor 4, that is, increase the loading height and adjust the loading position.

[0030] When faced with different car bodies, the telescopic cylinder 16 can make precise and detailed adjustments to the height and horizontal position of the discharge port of the adjusting belt conveyor 4 in a very short time, so that the loading machine can flexibly adapt to various car body sizes and different height requirements, significantly improving the adaptability to various car bodies and loading efficiency.

[0031] Specifically, the feeding unit 2 includes a feeding hood 21, inside which an auger 22 is rotatably mounted. Driven by a motor, the auger 22 rotates and continuously collects and pushes the surrounding coal to the discharge end, ensuring an efficient coal collection process. The discharge end of the auger 22 is equipped with a tilting feeding component 23, located at the inlet of the lifting conveyor belt 3. The tilting feeding component 23 smoothly tilts the coal fed by the auger 22 into the inlet of the lifting conveyor belt 3, achieving a stable and continuous transfer of coal from the feeding unit 2 to the lifting conveyor belt 3, effectively improving the stability and efficiency of the feeding process.

[0032] Specifically, the auger 22 includes two helical blades 221 with opposite directions of rotation. These two blades 221 are positioned on either side of the tilting feed assembly 23. When the auger 22 begins to rotate under the drive of a motor, the two helical blades 221 function simultaneously. The helical blade 221 on one side of the tilting feed assembly 23, according to its own rotation direction, rapidly pushes nearby coal towards the tilting feed assembly 23; while the helical blade 221 on the other side, with its opposite rotation direction, simultaneously pushes the coal in its area in the same direction. In this way, compared to the traditional single-helical-blade structure, the double-helical-blade design of the auger 22 can collect and transport more coal per unit time.

[0033] The simultaneous operation of the two spiral blades 221 expands the coal collection range, gathering coal from a larger surrounding space to the vicinity of the tipping feed assembly 23, effectively improving collection efficiency.

[0034] Specifically, the tipping feed assembly 23 includes a rotating shaft 231 fixedly connected to the auger 22, and multiple tipping plates 232 are evenly arranged on the outer wall of the rotating shaft 231. This ensures that coal at each position can be processed in a timely and effective manner during the rotation of the rotating shaft 231.

[0035] When the auger 22 drives the rotating shaft 231 to rotate, the tipping plate 232 on the rotating shaft 231 also performs a circular motion. During the rotation, the tipping plate 232 first contacts and inserts into the coal conveyed by the auger 22. As it rotates, the tipping plate 232 gradually lifts the coal upward, causing it to leave the conveying path of the auger 22.

[0036] Because the tipping plates 232 are evenly distributed, the coal is uniformly grasped and lifted in the circumferential direction. When the tipping plates 232 rotate with the coal to a position close to the feed inlet of the elevator belt 3, the coal falls smoothly into the feed inlet of the elevator belt 3 by its own gravity and the pushing action of the tipping plates 232.

[0037] In the technical solution of the tracked automatic loading machine, an advanced dust prevention system is specially designed to solve the dust pollution problem during the loading operation. The dust prevention water sprayer 6 equipped at the front end of the feeding unit 2 and the dust prevention water tank 5 connected to the upper end of the frame 100 are the core components of the system.

[0038] During the coal collection process, the feeding unit 2 inevitably generates a large amount of dust, which not only pollutes the working environment and affects the health of operators, but may also reduce the service life of the equipment. To effectively suppress dust, a dust suppression water sprayer 6 is installed at the front end of the feeding unit 2 to spray water evenly on the coal from all directions.

[0039] During use, press the button to open the butterfly valve 14 of the water pump to open the butterfly valve 14. Then start the water pump 13. Depending on the site conditions, the water pump 13 may not need to be started. The water pump 13 is controlled by a frequency converter, which can control the amount of water sprayed by the dust suppression sprayer 6 according to the moisture content of the coal or the amount of dust.

[0040] The dust suppression water sprayer 6 atomizes water into tiny droplets, increasing the contact area between the water and coal particles. These tiny droplets can quickly adhere to the surface of the coal particles, effectively suppressing dust generation.

[0041] To ensure the continuous and stable operation of the dust suppression water sprayer 6, a sufficient water supply is required. Therefore, a dust suppression water tank 5 is connected to the upper end of the frame 100.

[0042] Specifically, the discharge end of the shift conveyor belt 4 is equipped with a baffle plate 18. The baffle plate 18 can prevent coal from scattering to both sides during the discharge process, and ensure that the coal can fall accurately into the target area inside the vehicle cargo box along the set route and range under the push of the belt.
