Description

Technical Field

[0001] This invention relates to the field of mineral powder sampling equipment technology, and in particular to a telescopic waste disposal device for an automotive sampler. Background Technology

[0002] In existing mineral powder truck sampling operations, a vibrating chute is typically used for waste disposal. This traditional disposal method has the following significant drawbacks: Sticky materials such as mineral powder tend to adhere to the surface of the vibrating trough, resulting in incomplete unloading and requiring frequent manual cleaning.

[0003] Vibration motors generate significant mechanical noise when operating, impacting the on-site working environment.

[0004] The fixed vibrating feed chute has long occupied the space under the sampler, causing inconvenience for some vehicles (especially those with high cabs) and even causing collisions.

[0005] Traditional structures lack flexible obstacle avoidance mechanisms, making it difficult to accurately coordinate with the sampling machine's coordinate positioning, which can easily lead to material spillage. Summary of the Invention

[0006] To address the aforementioned technical problems, a telescopic waste disposal device for automotive sampling machines is provided. The technical means employed in this invention are as follows: A telescopic waste disposal device for an automotive sampling machine includes: The frame assembly is fixedly installed on the main body of the sampling machine, serving as the load-bearing foundation for the entire device; The suspension track is horizontally and fixedly installed on the frame assembly; The carriage assembly is slidably suspended on the suspension rail via a set of wheels; The waste material conveyor belt is fixedly installed on the slide assembly and moves together with the slide assembly to receive and transport waste materials; The walking drive mechanism includes a walking motor, a drive shaft, a driven shaft, and a synchronous transmission component. The walking motor is mounted on the carriage assembly, and its output shaft is connected to the drive shaft via a coupling. The drive shaft and the driven shaft are respectively mounted on the carriage assembly via bearing seats. Both ends of the drive shaft and the driven shaft are fixedly mounted with rollers, which roll in contact with the suspension track. The drive shaft and the driven shaft are connected by the synchronous transmission component to achieve synchronous rotation. The walking motor drives the drive shaft to rotate, causing the rollers to roll on the track, thereby driving the carriage assembly to reciprocate along the suspension track. A scraper is installed at the front end of the waste conveyor belt, and its scraper makes elastic contact with the belt surface to scrape off the material remaining on the belt surface. The PLC control unit is electrically connected to the walking motor and is used to control the start, stop and direction of the walking motor according to the working status of the sampler.

[0007] Furthermore, the carriage assembly includes a carriage body welded from several bent parts, and multiple rows of wheels mounted on the carriage body; the rows of wheels roll on the suspension track, and each row of wheels is mounted on an axle via a bearing, with the axle fixedly connected to the carriage body.

[0008] Furthermore, the waste conveyor belt includes: The driving roller and the driven roller are respectively mounted on both sides of the carriage assembly via bearings with square seats; A belt is wrapped around the driving and driven rollers; The worm gear reducer is mounted on the carriage assembly, and its output shaft is connected to the drive drum by a key. The belt conveyor drive motor is connected to the input shaft of the worm gear reducer to provide power; The electric pad, the active pad, and the driven pad serve as connecting pads between each component and the carriage assembly, and are fixed by bolts.

[0009] Furthermore, a chain drive mechanism is provided between the driving roller and the worm gear reducer, including a driving sprocket, a driven sprocket and a chain. The driving sprocket is mounted on the output shaft of the reducer, the driven sprocket is mounted on the shaft of the driving roller, and the chain connects the two sprockets.

[0010] Furthermore, the sweeper includes: The scraper mounting bracket is welded to the front end of the carriage assembly; The scraper shaft is rotatably mounted on the scraper mounting base; The crank is fixedly connected at one end to the scraper shaft and at the other end to the scraper. The scraper is made of polyurethane material, and its cutting edge makes elastic contact with the surface of the belt. The contact pressure between the scraper and the belt can be adjusted by adjusting the relative angle between the crank and the scraper shaft.

[0011] Furthermore, it also includes guard plates and baffles, wherein: Several guard plates are installed on both sides and the bottom of the waste material conveyor to prevent material from spilling. The baffle is installed behind the sweeper to guide the flow of materials.

[0012] Furthermore, the PLC control unit is connected to the main control system of the sampler. When the sampler moves to the waste disposal station, the PLC controls the walking motor to rotate forward, driving the carriage assembly to extend. The extension stroke is limited by the limit switches installed at both ends of the track. After the waste disposal is completed, the PLC controls the walking motor to rotate in reverse, driving the carriage assembly to retract and the device to reset.

[0013] The present invention has the following advantages: 1. The present invention adopts a sliding structure that combines a suspended track with a set of wheels, which has strong load-bearing capacity, low running resistance, and is suitable for harsh industrial environments.

[0014] 2. By adding a polyurethane scraper cleaner to the front end of the belt, the problem of mineral powder sticking to the material was effectively solved, and the material was prevented from spilling along the way.

[0015] 3. The vibration motor was eliminated and replaced with belt conveyor, which completely eliminated vibration noise and improved the working environment.

[0016] 4. The carriage retraction and extension are achieved by directly driving the wheel trolley with a walking motor. This method features a compact structure and high transmission efficiency, avoiding the problems of limited stroke and large installation space required by traditional electric push rods. The motor-driven belt extension and retraction function enables the carriage to extend when needed and retract when not in use, greatly facilitating vehicle passage. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] like Figures 1-5 As shown, this embodiment of the invention discloses a telescopic waste disposal device for an automotive sampling machine, including a frame assembly 1, a suspension rail, a carriage assembly, a waste disposal belt conveyor, a walking drive mechanism, a sweeper, and a PLC control unit.

[0025] The frame assembly 1 is the installation foundation of the entire device. It is made of welded steel profiles and includes three protective plates: the first protective plate 12, the second protective plate 22, and the third protective plate 23.

[0026] The frame assembly 1 is bolted to the lower support of the main body of the sampling machine. A horizontal suspension rail, made of I-beams, is mounted on the frame assembly 1 and is fixedly connected to it by bolts or welding. Limit blocks are provided at both ends of the rail to restrict the travel range of the carriage.

[0027] The carriage assembly is used to support the waste material conveyor belt and enable it to slide along a track. The carriage assembly includes a carriage body welded from a first bent component 3 and a second bent component 4, and multiple rollers 2 mounted on the carriage body. The rollers 2 employ a rolling bearing structure and are mounted on both sides of the carriage body via axles. The axle of each roller 2 is welded and fixed to the carriage body, and the roller 2 body rotates freely around its axle. The carriage body is suspended on a suspension track via the rollers 2, and the rollers 2 roll on the track, achieving smooth movement of the carriage assembly.

[0028] The carriage body also has multiple mounting surfaces for mounting various components of the waste material conveyor, including an electric mounting plate 6, a drive mounting plate 7, and a driven mounting plate 21. These mounting plates are all machined steel plates and are fixedly connected to the carriage body with bolts, used to adjust the mounting height and position of each component. The drive mounting plate 7 is provided with bearing seats 18 for mounting the bearings of the drive shaft 9 and the driven shaft 10. The electric mounting plate 6 is installed on the side of the carriage body near the travel motor and is used to mount the travel motor 19.

[0029] The travel drive mechanism is used to drive the carriage assembly to extend and retract along the track. The travel drive mechanism includes a travel motor 19, a drive shaft 9, a driven shaft 10, and a synchronous transmission component. The travel motor 19 is mounted on the carriage body, and its output shaft is connected to the drive shaft 9 via a coupling. The drive shaft 9 and the driven shaft 10 are respectively mounted on the carriage body via bearing seats. Both ends of the drive shaft 9 and the driven shaft 10 are fixedly mounted with rollers 2, which roll in contact with the suspension track. The drive shaft 9 and the driven shaft 10 are connected by a synchronous transmission component. In this embodiment, the synchronous transmission component is a chain 11. A drive sprocket 8 is mounted on the drive shaft 9, and a driven sprocket is mounted on the driven shaft 10. The chain 11 on the same side connects the two sprockets on the same side, achieving synchronous rotation of the drive shaft 9 and the driven shaft 10. When the walking motor starts, it drives the drive shaft 9 to rotate. When the drive shaft 9 and the driven shaft rotate synchronously, all the rollers 2 roll synchronously on the suspension track. That is, the rollers 2 on the drive shaft 9 rotate accordingly. At the same time, the chain 11 drives the driven shaft 10 and the rollers 2 on the driven shaft 10 to rotate synchronously, thereby driving the entire carriage assembly to move smoothly along the track.

[0030] The waste conveyor belt is installed on the carriage assembly and moves together with the carriage. It is used to receive the mineral powder waste unloaded by the sampler and transport it to the silo.

[0031] Specifically, in the travel drive mechanism, both ends of the drive shaft 9 and driven shaft 10 are equipped with rollers 2, which roll in contact with the flanges of the suspension track. The travel motor is mounted on the carriage body and connected to the drive shaft 9 via a coupling. A drive sprocket is also fixed on the drive shaft 9, and a driven sprocket is fixed on the driven shaft 10. A chain 11 connects the drive sprocket and the driven sprocket, enabling synchronous rotation of the two shafts. When the travel motor rotates forward, the rollers 2 on the drive shaft 9 rotate counterclockwise, driving the carriage assembly to move in the extension direction; when the travel motor rotates in reverse, the carriage assembly retracts. The start, stop, and direction of the travel motor are controlled by a PLC control unit.

[0032] The waste material conveyor belt includes an independent conveyor belt drive motor and a reducer, which are used to drive the belt to run. Its specific structure can adopt the design of a conventional belt conveyor, which will not be described in detail here.

[0033] The scraper is installed at the front end of the waste conveyor belt to scrape off mineral powder adhering to the surface during the belt's return stroke. The scraper includes a scraper mounting base 14, a scraper shaft 15, a crank 17, and a scraper 16. The scraper mounting base 14 consists of two steel plates welded to both sides of the front end of the carriage body. The scraper shaft 15 is made of round steel and is rotatably mounted at both ends in the bearing holes of the scraper mounting base 14. One end of the crank 17 is connected to the scraper shaft 15 by a key, and the other end has an elongated hole for bolt connection to the scraper 16. The scraper 16 is made of polyurethane material, and its cutting edge makes elastic contact with the surface of the belt 20. The contact pressure between the scraper 16 and the belt 20 can be adjusted by adjusting the position of the bolts on the crank 17. A baffle 13 is also provided behind the scraper 16 to guide the flow of scraped material.

[0034] The PLC control unit is installed inside the sampling machine control cabinet and is electrically connected to the walking motor and the conveyor drive motor of the waste material conveyor, as well as to the main control system of the sampling machine. Limit switches are installed at both ends of the track, corresponding to the retracted limit position and the extended limit position, respectively. The signals from the limit switches are connected to the PLC control unit.

[0035] The PLC control unit is connected to the main control system of the sampler. When the sampler moves to the waste disposal station, the PLC controls the travel motor to rotate forward, driving the carriage assembly to extend. The extension stroke is limited by limit switches installed at both ends of the track. After waste disposal is completed, the PLC controls the travel motor to rotate in reverse, driving the carriage assembly to retract and resetting the device. Optionally, inductive proximity switches are installed at both ends of the track. When the carriage assembly moves to its limit position, the wheel 2 triggers the proximity switch, and the switch signal is connected to the input terminal of the PLC control unit to cut off the power supply to the travel motor and record the current position.

[0036] The specific workflow of this invention is as follows: Status A: The PLC controls the walking motor to be in a stopped state, the carriage assembly is located at the retracted limit position of the track, the waste material conveyor is completely retracted to the bottom of the sampling machine body, does not occupy the space below, and the vehicle can pass freely.

[0037] Status B: When the sampler completes sampling and moves above the waste hopper, the sampler's main control system sends a waste signal to the PLC. The PLC controls the travel motor to rotate forward, driving the carriage assembly to extend outward along the track until it touches the limit switch at the extension limit position, at which point the travel motor stops. At this time, the waste conveyor belt extends above the waste hopper, with an extension length of approximately 1000mm.

[0038] Disposal: The sampler flips over to unload, and the material falls onto belt 20. Simultaneously, the belt drive motor of the disposal conveyor starts, and belt 20 transports the material to the hopper. During the belt return stroke, the scraper 16 of the cleaner scrapes away any mineral powder adhering to the belt surface in real time.

[0039] Reset: After unloading is completed, the sampler sends a completion signal, the PLC controls the walking motor to reverse, drives the carriage assembly to return to the retracted limit position, the walking motor stops, and the device returns to state A.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
