Description

Technical Field

[0001] This utility model relates to a multi-station material distribution device, belonging to the field of material transfer and allocation technology. Background Technology

[0002] Unloading devices are automated equipment widely used in industry, construction, transportation, and other fields. They are mainly used for material conveying, loading, unloading, and sorting, and are characterized by improved efficiency, reduced labor intensity, and enhanced safety. Based on application scenarios and technical characteristics, unloading devices can be divided into several types. Currently, the most common multi-point unloading devices are mainly divided into two categories: fixed plow-type unloaders and mobile unloading vehicles.

[0003] In existing technologies, the unloading components of fixed plow-type unloaders are prone to wear, which causes significant wear on the conveyor belt and affects its service life. Furthermore, fine-particle materials are prone to leaking out from the gap between the unloading plate and the conveyor belt, posing a risk of incomplete unloading and material mixing. Mobile unloading vehicles have complex structures, large operating spaces, and are difficult to operate in a fully enclosed manner. They also require dust removal systems, resulting in high overall system investment. Summary of the Invention

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a multi-station material distribution device. It solves the technical problem of distributing different materials to multiple silos with only one device, simplifies the system process, reduces the number of devices and failure points, has a compact layout, and the material distribution device has a fully enclosed chute design, eliminating the need for a dust removal system. The device is simple, highly reliable, and reduces construction and operating costs.

[0005] To achieve the above objectives, this utility model employs the following technical solution:

[0006] In a first aspect, this utility model provides a multi-station material distribution device, including a steel rail fixedly installed between a feeding section and a multi-station distribution bin, with wheel stops at both ends of the steel rail. A vehicle body is mounted between the rails, and multiple sets of wheels are symmetrically installed on both sides of the vehicle body, with each set of wheels rolling in cooperation with the rails on both sides. A drive device is fixedly installed on the vehicle body and is fixedly connected to one set of wheels. A distribution chute is fixedly connected to the vehicle body, and the distribution chute has multiple chutes corresponding to the multi-station distribution bins. When the vehicle body moves to a designated position on the steel rail, the feeding section, one chute of the distribution chute, and one bin of the multi-station distribution bin form a material distribution path. A guide channel is provided on the inner wall of the distribution chute.

[0007] Furthermore, the multi-station distribution chute is a three-station distribution chute, and the distribution chute is provided with three chutes: left, middle, and right. When the car body moves to the middle position of the rail, the feeding unit corresponds to the middle chute of the three-station distribution chute through the middle chute of the distribution chute. When the car body moves to the right stop, the feeding unit corresponds to the left chute of the three-station distribution chute through the left chute of the distribution chute. When the car body moves to the left stop, the feeding unit corresponds to the right chute of the three-station distribution chute through the right chute of the distribution chute.

[0008] Furthermore, the drive device includes a reversible variable frequency drive motor, a reduction gear, and a main drive shaft. The variable frequency drive motor is connected to the main drive shaft through the reduction gear, and the main drive shaft is connected to a set of wheels on the vehicle body.

[0009] Furthermore, the vehicle body is welded from steel plates and structural steel, forming an overall frame structure, and is fixed to the top periphery of the distribution chute.

[0010] Furthermore, the distribution chute is welded from steel plates and structural steel, and then welded to the structural steel of the vehicle body as a whole.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0020] The following detailed description is exemplary and intended to provide further detailed explanation of the present invention. Unless otherwise specified, all technical terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this invention is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this invention.

[0021] Example:

[0022] Please see Figures 1 to 3 This embodiment proposes a multi-station material distribution device, specifically including a drive unit 1, a vehicle body 2, wheels 3, a distribution chute 4, a rail 5, and a stop 6. The drive unit 1 is fixedly installed on the vehicle body 2. Multiple sets of wheels 3 are installed on the left and right sides of the vehicle body 2. A rail 5 is fixedly installed above the silo top. The vehicle body 2 is supported by the wheels 3 and can move along the rail 5. The drive unit 1 consists of a variable frequency drive motor, a reduction gear, and a main drive shaft. The variable frequency drive motor is connected to the main drive shaft through the reduction gear, and the main drive shaft is connected to a set of wheels 3 on the vehicle body 2. The variable frequency drive motor can rotate in both directions, driving the wheels 3 of the material distribution device to rotate through the reduction gears. This causes the entire vehicle body 2 of the material distribution device to reciprocate on the rails 5. Stops 6 are located at both ends of the rails 5. A distribution chute 4 is fixedly connected to the inner side of the vehicle body 2, and the inner wall of the distribution chute 4 is equipped with guide channels to guide the material movement trajectory and improve the material movement speed. The distribution chute 4 has three channels: left, middle, and right, corresponding to the three-station distribution positions. The feeding section 7 is located above the vehicle body 2, and its size and position are matched to the top inlet of the distribution chute 4. Figure 1 The state shown is that the feeding unit 7 distributes materials to the intermediate bin through the middle chute. When the device moves to the right to the right stop 6 position, the feeding unit 7 distributes materials to the left bin through the left chute of the distribution chute 4. When the device moves to the left to the left stop 6 position, the feeding unit 7 distributes materials to the right bin through the right chute of the distribution chute 4.

[0023] It should be noted that the car body 2 is welded from steel plates and shaped steel, forming an overall frame structure, and is fixed to the top periphery of the distribution chute 4; the wheels 3 adopt a steel wheel structure, wherein the steel wheels not connected to the drive device 1 are rotatably connected to the side wall of the car body 2 through bearings, wheel axles, and connecting bolts; the distribution chute 4 is welded from steel plates and shaped steel, and is welded to the shaped steel of the car body 2 as a whole, and multiple chute 4 can be set according to different work positions; the rails 5 are made of 22# mining H-beams; the stop 6 is welded from steel plates and is welded and fixed to the rails 5 to realize the fixing and limiting of different work positions of the material distribution device; the multi-work position material distribution device can move freely on the rails 5 on the top of the silo, and is moved to a fixed work position by the drive device 1 to realize the distribution of different materials.

[0024] This solution proposes a multi-station material distribution device that can solve the problem of distributing different materials with only one device. Compared with traditional unloading devices, the system is simple, the distribution chute is fully enclosed, and there is no need for a dust removal system. This reduces system components and equipment failure points, and the layout is compact. The equipment is simple, highly reliable, and reduces construction and operating costs, resulting in good economic benefits.

[0025] To achieve coordinated control of workstation distance, chute inclination angle, and operating speed, thereby ensuring zero leakage in material distribution, this solution further improves upon the above, including vehicle movement and positioning distance calculation, chute anti-clogging inclination angle verification, and frequency converter speed optimization. Specifically:

[0026] (i) The distance the vehicle body moves to the target is calculated in real time using a PLC controller, and the stroke of the variable frequency motor is controlled accordingly. The formula is as follows:

[0027] Dm = Lp - Do

[0028] In the formula: Dm is the target distance of the vehicle body movement (calculated result, unit: m); Lp is the distance between the center point of the current workstation and the center point of the target workstation (measured value, unit: m), which is obtained in real time by a laser rangefinder with a pre-set workstation mark on the rail; Do is the offset between the center of the chute inlet and the center of the vehicle body (design value, unit: m), which is obtained by measurement and stored in the PLC controller.

[0029] (ii) Verify whether the welding angle of the chute is not less than the minimum safe angle of the chute using the PLC controller. The formula is:

[0030] α=arctan(μc)+θ

[0031] In the formula: α is the minimum safe tilt angle of the chute (calculated result, unit: °); μc is the dynamic friction coefficient between the material and the chute steel plate (measured value of physical property), determined by laboratory material friction test; θ is the safety margin angle (empirical value, unit: °), generally 5°.

[0032] (III) The PLC dynamically limits the upper limit of the operating speed based on the maximum allowable operating speed of the vehicle body. The formula is as follows:

[0033]

[0034] In the formula: Vspeed is the maximum permissible operating speed of the vehicle body (calculated result, unit: m / s); Kv is the conversion coefficient between motor frequency and wheel speed (calibrated value); f is the output frequency of the variable frequency motor (set value, unit: Hz); ρ is the actual bulk density of the material (real-time value from the sensor, unit: t / m³). 3 ), which is the real-time monitoring data of the microwave density meter on the top of the silo; ρmax is the maximum material density designed by the system (set value, unit: t / m³). 3 Kv and ρmax are the device's factory performance parameters stored in the PLC.

[0035] The actual operation steps are as follows:

[0036] Step 1: The PLC calls the formula to calculate the target distance the vehicle body needs to move.

[0037] Lp (distance between center and right workstations) = 3.2m (confirmed by laser ranging), Do (chute offset) = 0.4m (read from database), output result: Dm = 3.2 - 0.4 = 2.8m → displacement of the driving target.

[0038] Step 2: The PLC calls the formula for the maximum allowable running speed of the vehicle body to adjust the speed:

[0039] ρ (current coal density) = 0.85 t / m³ 3 ρmax=1.1t / m 3 Kv = 0.02, f = 45Hz, output result: Vspeed = 0.02 × 45 × 0.85 / 1.1 = 0.73m / s → Set the upper limit of speed.

[0040] Step 3: Start the variable frequency motor to drive the vehicle body to move 2.8m to the right side of the vehicle stop, and align the left exit of the chute with the right compartment.

[0041] Anti-blocking verification: The chute inclination angle was checked using the minimum safe inclination angle formula, μc (coal to steel plate) = 0.45 (material property table), θ = 5°, and the output result was: α = arctan(0.45) + 5° ≈ 29° → the actual chute inclination angle is 32° > α, which meets the anti-blocking requirements.

[0042] In summary, this solution replaces multiple traditional unloading devices with a single unit, eliminates dust collection and encloses the space, reducing auxiliary equipment investment and ductwork layout, significantly compressing civil engineering space and improving structural simplicity. Based on triple collaborative control using workstation offset, dynamic speed regulation of material density, and anti-blocking tilt angle verification, it avoids mixed material spillage and ensures full-load flow, achieving intelligent control. The rigid welded car body-chute integrated structure eliminates shaking and leakage, while the mechanical limiter on the rails improves positioning accuracy and impact resistance, ensuring operational reliability. Variable frequency drive reduces start-stop impact energy consumption, and the fully enclosed flow channel eliminates the power consumption of the dust collection system, resulting in significant advantages in overall construction and operating costs, leading to cost reduction.
