Description

Technical Field

[0001] The present invention relates to the technical field of material transportation, and in particular to a silo material loading structure and method. Background Art

[0002] In the field of bulk stone transportation, using a conveyor belt to load materials such as gravel into truck compartments is a common operation. Traditional fixed-angle conveyors present two major pain points during loading: First, to achieve uniform material distribution across the front and rear of the truck compartment, the truck must be frequently shifted, significantly reducing loading efficiency. Second, dust pollution generated during gravel unloading is a prominent problem. Due to vibration and gravity, the fine dust particles in the gravel often accumulate on the surface layer of the conveyor belt. This means that a large amount of fine stone powder is located at the bottom of the conveyor belt, while the granular gravel is located in the middle and upper parts of the conveyor belt. Existing dust suppression solutions generally use rooftop spray systems, but their design has fundamental flaws. The dust suppression liquid sprayed from the roof is affected by spatial barriers and time delays, making it difficult to quickly penetrate the middle and upper layers of gravel to reach the stone powder-rich area at the bottom of the conveyor belt. As a result, the dust suppression liquid cannot quickly and effectively combine with the dust, generating a large amount of fugitive dust when loading into the truck compartment. At the same time, if the dust suppression effect is to be maximized, traditional spraying requires continuous large amounts of water to cover the entire working area. Not only is the water resource utilization rate low, but it is also unable to accurately act on the core of the dust source (the contact surface between the bottom of the guide belt and the stone), resulting in poor dust suppression effect.

[0003] Therefore, in view of this, the inventors propose a silo material loading structure and method to solve the above technical problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a silo material loading structure to solve the problem that the existing loading structure uses a fixed-angle guide belt to load, which requires frequent moving of the truck, resulting in operational inconvenience, and the dust suppression liquid cannot quickly contact the stone powder at the bottom of the guide belt, resulting in poor dust suppression effect; the second purpose is to propose a method.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is as follows: A silo material loading structure comprises a support platform, a material conveyor and a material guide unit; the material conveyor is installed on the support platform; The material guide unit has an input end and an output end, the input end is connected to the material conveyor, and the output end extends into the truck compartment; The material guiding unit includes a material guiding frame installed at the end of the material conveyor and a material guiding platform movably arranged on the material guiding frame, the material guiding platform includes a first operating state and a second operating state, and the material guiding platform is configured to be switchable between the first operating state and the second operating state; Dust suppression liquid is stored inside the material guide platform; A driving mechanism is pivotally connected to the material guide frame and connected to the material guide platform; the driving mechanism is constructed to drive the material guide platform to switch from the first operating state to the second operating state, and synchronously trigger the dust suppression liquid inside the material guide platform to be pressurized and sprayed out.

[0006] Furthermore, the material guiding platform includes two telescopic plates and a cross frame, the cross frame is arranged between the two telescopic plates, and the two telescopic plates are arranged in parallel; Each of the telescopic plates includes a plurality of telescopic units, and each of the telescopic units is connected end to end; The telescopic unit includes a first plate and a second plate, the second plate being connected to the first plate of the adjacent telescopic unit, a first liquid storage cavity being defined in the first plate, the second plate being sealingly and slidably connected in the first liquid storage cavity, the first liquid storage cavity being defined with a plurality of liquid outlets, each of the liquid outlets being provided with a spray element, and when the pressure in the first liquid storage cavity increases, the dust suppression liquid in the first liquid storage cavity is sprayed outward through the spray element; It also includes a first liquid supply pipe, which is connected to each of the first liquid storage chambers and is used to supply dust suppression liquid to the first liquid storage chambers.

[0007] Furthermore, the spray part includes a seat body, a spring and a sealing ball. The seat body is installed at the liquid outlet. A spray flow channel connected to the first liquid storage chamber is opened in the seat body. The spring and the sealing ball are arranged in the spray flow channel. The spring has a tendency to drive the sealing ball to block the spray flow channel.

[0008] Furthermore, the driving mechanism is a hydraulic cylinder, and the number of the hydraulic cylinder is one or more; The piston end of the hydraulic cylinder is hinged to one of the telescopic plates or the cross frame.

[0009] Furthermore, the first liquid supply pipe extending into the first liquid storage cavity is provided with a one-way valve, and the first liquid supply pipe is connected to a dust suppression liquid tank; The driving mechanism periodically drives the material guiding platform to switch between the first operating state and the second operating state; when the material guiding platform switches from the second operating state to the first operating state, the dust suppression liquid tank supplies dust suppression liquid to the first liquid storage chamber through the first liquid supply pipe; When the material guiding platform is switched from the first operating state to the second operating state, the dust suppression liquid is sprayed outward from the first liquid storage chamber through the spray flow channel.

[0010] Furthermore, the two telescopic plates are respectively an upper telescopic plate and a lower telescopic plate, the spraying member located on the upper telescopic plate is located on the upper surface of the upper telescopic plate; the spraying member located on the lower telescopic plate is located on the lower surface of the lower telescopic plate.

[0011] Furthermore, each of the second plates is provided with a second liquid storage cavity, and each of the second plates is provided with a plurality of nozzles communicating with the second liquid storage cavity; It also includes a second liquid supply pipe, which is connected to the second liquid storage chamber.

[0012] Furthermore, a screening structure is provided above the material conveyor, and the screening structure is connected to the silo.

[0013] Furthermore, the support platform includes a first support seat and a second support seat, the material guide frame is arranged above the second support seat, and the second support seat can be extended or shortened to drive the material guide frame to rise or fall.

[0014] On the other hand, the present application also proposes a method for loading silo materials, which adopts the aforementioned silo material loading structure and further includes the following steps: S1: Park the truck in front of the support platform, adjust the height of the material guide unit to match the truck compartment, and start the material conveyor to transport gravel to the material guide platform in the first operating state; S2: The driving mechanism is activated to drive the material guiding platform to the second operating state. The telescopic plate contracts to move the material placement point backwards to distribute the material to the rear of the truck compartment. At the same time, the second plate compresses the first liquid storage chamber to trigger the dust suppression liquid to spray upward on the surface of the telescopic plate. S3: The material guide table is driven to return to the first operating state, the telescopic plate is extended to move the material drop point forward to distribute the material to the front of the truck compartment, and the dust suppression liquid is replenished through the one-way valve; S4: Repeat S2-S3 to form periodic swing distribution and synchronous spraying until the truck compartment is evenly loaded.

[0015] Beneficial effects of the present invention: The present invention uses a drive mechanism to periodically drive the material guide platform between its first and second operating states. During this process, the length of the material guide platform changes dynamically, causing its output end (drop point) to automatically and regularly oscillate within the vehicle compartment, from front to back and back again, while the truck remains completely stationary. This dynamic oscillating material distribution mechanism completely resolves the drawback of conventional fixed material guides, which rely on frequent truck movement to achieve uniform material distribution across the front and back of the vehicle compartment, significantly improving loading efficiency. Simultaneously, during the crucial transition from the first to the second state of the material guide platform, the second plate of the telescopic unit simultaneously compresses the first liquid reservoir. The mechanical motion of the structure itself generates high pressure, instantly triggering the spray element to activate and spray dust suppression liquid directly and precisely onto the stone dust-rich layer (the core dust source area) adjacent to the upper telescopic plate surface (i.e., the bearing surface of the material guide platform). The dust suppression liquid quickly binds to the dust source without penetrating the upper gravel layer, fundamentally addressing the fundamental drawback of conventional roof-mounted sprays, which have difficulty reaching underlying dust sources and resulting in poor dust suppression effectiveness.

[0016] The second plate of the present invention slides into the first liquid storage cavity of the first plate, naturally forming a strong compression of the volume of the liquid storage cavity, thereby instantly generating the required high pressure, forcing the dust suppression liquid to overcome the spring resistance in the spray part, push open the blocking ball and spray out forcefully. This design abandons the traditional dust suppression method that relies on additional water pumps and complex control systems. It has a simple structure, low energy consumption and extremely fast response. The spraying action only occurs when the drop point where dust suppression is required moves backward, and the dust suppression liquid is precisely guided to the bottom of the material layer on the surface of the material guide table, the core area where dust is generated, avoiding the waste of water resources caused by traditional large-scale continuous spraying. After the spraying is completed, during the extension and reset process of the material guide table, the low pressure formed by the increase in the volume of the first liquid storage cavity is used to automatically replenish the dust suppression liquid through the one-way valve to prepare for the next spray cycle, thereby realizing efficient closed-loop management of the supply and consumption of dust suppression liquid.

DETAILED DESCRIPTION

[0020] The following describes the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art will readily appreciate the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the various details in this specification may be modified or altered based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are intended only to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0021] It should be noted that the illustrations provided in the following embodiments are merely schematic illustrations of the basic concept of the present invention. Therefore, the illustrations only show components related to the present invention and are not drawn according to the number, shape, and size of components in actual implementation. In actual implementation, the type, quantity, and proportion of each component may be changed arbitrarily, and the component layout may also be more complex.

[0022] This embodiment proposes a silo material loading structure, such as Figures 1 to 7As shown, it includes a support platform 11, a material conveyor 12 and a material guiding unit 13; the material conveyor 12 is installed above the support platform 11; the material guiding unit 13 has an input end and an output end, the input end is connected to the material conveyor 12, and the output end extends to the truck compartment; the gravel in the silo first enters the material conveyor 12, the material conveyor 12 conveys the gravel to the material guiding unit 13, and the material guiding unit 13 conveys the gravel to the truck compartment, completing the transportation of the gravel from the silo to the truck compartment.

[0023] The material guide unit 13 includes a material guide frame 131 installed below the end of the material conveyor 12 and a material guide platform 132 movably arranged on the material guide frame 131. The material guide platform 132 is connected to the material conveyor 12. The material guide platform 132 includes a first operating state (such as Figure 2 ) and the second job status (such as Figure 3 ), the material guide platform 132 is configured to be switchable between a first operating state and a second operating state; the material guide platform 132 is internally stored with dust suppression liquid, and the dust suppression liquid is preferably water.

[0024] It also includes a driving mechanism 133, which is pivotally connected to the material guide frame 131 and connected to the material guide platform 132; the driving mechanism 133 is constructed to: drive the material guide platform 132 to switch from the first operating state to the second operating state, and synchronously trigger the dust suppression liquid inside the material guide platform 132 to be pressurized and sprayed out.

[0025] In this embodiment, support platform 11 serves as a foundation supporting material conveyor 12, which delivers silo material (gravel) to the input end of material guide unit 13. A guide frame 131 of guide unit 13 is fixed to the end of material conveyor 12. A guide platform 132 is movably mounted on the frame and has two operating states. Initially, guide platform 132 is in its first operating state, where dust suppression liquid is replenished from the dust suppression liquid tank via first liquid supply pipe 1345 into first liquid storage chamber 1343 of guide platform 132. When loading is required, the driving mechanism 133 (such as a hydraulic cylinder) is started, pushing the material guiding platform 132 to switch from the first operating state to the second operating state, and then from the second operating state to the first operating state. During the extension process to the first operating state, the cross frame 1322 drives the telescopic plate 1321 to extend, the angle of the material guiding platform 132 changes and the landing point moves forward, and the material slides to the front of the truck compartment (near the front position); during the contraction process to the second operating state, the material guiding platform 132 retracts, the angle of the material guiding platform 132 changes and the landing point moves backward, and the gravel slides to the rear of the truck compartment. Through continuous reciprocating drive, the material guide platform 132 lands in the truck compartment and swings regularly from front to back and then from back to front, cooperating with the continuous feeding of the material conveyor 12, so that the gravel forms a uniform accumulation layer in the truck compartment; when the first operating state is converted to the second operating state, the internal space of the material guide platform 132 is squeezed, and the pressure of the first liquid storage chamber 1343 increases sharply, and the dust suppression liquid is sprayed out from the material guide platform 132. Since stone powder is usually enriched at the bottom of the material guide platform 132, the sprayed dust suppression liquid can quickly contact and combine with the stone powder at the bottom, directly act on the material layer at the bottom of the material guide platform 132, and instantly infiltrate the fine stone powder enriched in the material guide platform 132, so as to achieve precise dust suppression in the core area of ​​the dust source.

[0026] As a preferred embodiment, the guide platform 132 includes two telescopic plates 1321 and a cross frame 1322. The cross frame 1322 is arranged between the two telescopic plates 1321, and the two telescopic plates 1321 are arranged in parallel. Each telescopic plate 1321 includes a plurality of telescopic units 134, and each telescopic unit 134 is connected end to end; the telescopic unit 134 includes a first plate body 1341 and a second plate body 1342. The second plate body 1342 is connected to the first plate body 1341 of the adjacent telescopic unit 134. The first plate body 1341 is provided with a plurality of telescopic units 134. The first liquid storage chamber 1343, the second plate 1342 is sealed and slidably connected in the first liquid storage chamber 1343, the first liquid storage chamber 1343 is provided with a plurality of liquid outlets 1344, and the liquid outlets 1344 are each provided with a spraying member 135. When the pressure of the first liquid storage chamber 1343 increases, the dust suppression liquid in the first liquid storage chamber 1343 is sprayed outward through the spraying member 135; it also includes a first liquid supply pipe 1345, the first liquid supply pipe 1345 is connected to each first liquid storage chamber 1343, and is used to supply dust suppression liquid to the first liquid storage chamber 1343.

[0027] The spray element 135 includes a seat body 1351, a spring 1352 and a sealing ball 1353. The seat body 1351 is installed at the liquid outlet 1344. A spray channel 1354 connected to the first liquid storage chamber 1343 is opened in the seat body 1351. The spring 1352 and the sealing ball 1353 are arranged in the spray channel 1354. The spring 1352 has a tendency to drive the sealing ball 1353 to block the spray channel 1354.

[0028] The driving mechanism 133 is a hydraulic cylinder, and the number of the hydraulic cylinders is one or more; when multiple hydraulic cylinders are used, the stability of the overall structure can be improved and the driving power can be stronger. The piston end of the hydraulic cylinder is hinged to one of the telescopic plates 1321 or the cross frame 1322. In this embodiment, the piston end of the hydraulic cylinder is hinged to one of the telescopic plates 1321.

[0029] In this embodiment, two parallel telescopic plates 1321 are connected by a cross frame 1322 to form a material guide channel with adjustable length. Each telescopic plate 1321 is composed of several telescopic units 134 connected end to end. The first liquid storage chamber 1343 of the first plate 1341 is sealed and slidably connected to the second plate 1342. When the drive mechanism 133 pushes the material guide platform 132 from the first operating state to the second operating state, the second plate 1342 slides within the first liquid storage chamber 1343, compressing the space in the first liquid storage chamber 1343 and causing a sudden increase in internal pressure. At this time, the spray element 135 at the liquid outlet 1344 is pressurized to open: the spring 1352 is compressed, the sealing ball 1353 disengages the spray channel 1354, and the dust suppression liquid in the first liquid storage chamber 1343 is sprayed outward through the spray channel 1354, directly covering the material layer on the upper surface of the material guide platform 132. Because stone dust accumulates at the bottom of the material guide platform 132, the sprayed dust suppression liquid quickly contacts and combines with the stone dust at the bottom, effectively suppressing dust. Furthermore, the telescopic plate 1321, linked with the cross frame 1322, adjusts the length of the material guide channel to accommodate the loading requirements of different truck compartments. When the material guide platform 132 returns from the second operating state to the first operating state, the second plate 1342 retracts, increasing the volume of the first liquid storage chamber 1343 and reducing the pressure.

[0030] As a preferred embodiment, a first liquid supply pipe 1345 extends into the first liquid storage chamber 1343 and is provided with a one-way valve. The first liquid supply pipe 1345 is connected to a dust suppression liquid tank. The one-way valve allows dust suppression liquid to enter the first liquid storage chamber 1343 in one direction, but prevents the dust suppression liquid in the first liquid storage chamber 1343 from entering the dust suppression liquid tank in the reverse direction. The drive mechanism 133 periodically drives the material guide platform 132 to switch between a first operating state and a second operating state. When the material guide platform 132 switches from the second operating state to the first operating state, the dust suppression liquid tank supplies dust suppression liquid to the first liquid storage chamber 1343 via the first liquid supply pipe 1345. When the material guide platform 132 switches from the first operating state to the second operating state, the dust suppression liquid is sprayed out of the first liquid storage chamber 1343 through the spray channel 1354.

[0031] In this embodiment, a hydraulic cylinder serves as the driving source. When the hydraulic cylinder extends and retracts, it pushes the guide platform 132 between the first and second operating states. When the first operating state transitions to the second operating state, the second plate 1342 slides within the first liquid storage chamber 1343, compressing the space in the first liquid storage chamber 1343 and causing a sudden increase in internal pressure. At this point, the spring 1352 within the spray channel 1354 contracts under pressure, causing the sealing ball 1353 to disengage from the channel entrance. The dust suppression liquid within the first liquid storage chamber 1343 is sprayed outward through the spray channel 1354, directly covering the stone powder material layer at the bottom of the guide platform 132. When the hydraulic cylinder reverses its action, returning the guide platform 132 from the second operating state to the first operating state, the second plate 1342 retracts and no longer compresses the first liquid storage chamber 1343. The volume of the first liquid storage chamber 1343 increases, causing the pressure to decrease. The spring 1352 recovers its shape, pushing the sealing ball 1353 to reseal the spray channel 1354, thus stopping spraying. Through the periodic drive of the hydraulic cylinder, the posture adjustment of the material guide platform 132 and the spraying of the dust suppression liquid are synchronously controlled. When switching from the first operating state to the second operating state, pressurized spraying is used to suppress the stone powder dust at the bottom. When switching from the second operating state to the first operating state, the dust suppression liquid is replenished to prepare for the next spraying, ensuring that the dust suppression liquid acts accurately on the core area of ​​the dust source.

[0032] In this embodiment, the two telescopic plates 1321 are an upper telescopic plate 1321 and a lower telescopic plate 1321 , respectively. The spraying member 135 located on the upper telescopic plate 1321 is located on the upper surface of the upper telescopic plate 1321 ; the spraying member 135 located on the lower telescopic plate 1321 is located on the lower surface of the lower telescopic plate 1321 . When the driving mechanism 133 pushes the material guide platform 132 to switch from the first working state to the second working state, the first liquid storage chamber 1343 of the upper telescopic plate 1321 and the lower telescopic plate 1321 are both pressurized, and the internal pressure increase triggers the spray part 135 to open. The spray part 135 of the upper telescopic plate 1321 is located on the upper surface, and the dust suppression liquid is sprayed directly onto the upper surface of the upper telescopic plate 1321 (that is, the bottom of the gravel material layer). The sprayed dust suppression liquid quickly contacts and combines with the stone powder at the bottom of the gravel material layer, and instantly infiltrates the stone powder enriched in the material guide platform 132, thereby achieving precise dust suppression in the core area of ​​the dust source; the spray part 135 of the lower telescopic plate 1321 is located on the lower surface, and sprays the dust generated when the gravel is loaded, forming a dust suppression network from the material surface to the bottom, thereby better achieving the dust suppression effect.

[0033] As another embodiment, each second plate 1342 has a second liquid storage cavity 1346 formed therein, and each second plate 1342 has a plurality of nozzles 1347 communicating with the second liquid storage cavity 1346. A second liquid supply pipe 1348 is also provided, communicating with the second liquid storage cavity 1346. A screening structure 2 is provided above the material conveyor 12 and is connected to the silo.

[0034] This embodiment is mainly aimed at gravel transportation scenarios with small gravel particles and more stone powder. The liquid in the second liquid storage chamber 1346 is sprayed outward through the nozzle 1347 to form an auxiliary dust suppression layer that complements the spraying of the first liquid storage chamber 1343. Combined with the spraying of the first liquid storage chamber 1343, a multiple dust suppression network is formed. The second liquid supply pipe 1348 continuously replenishes liquid to the second liquid storage chamber 1346 to ensure that the nozzle 1347 always has the spraying ability, thereby improving the control of dust during loading, and enhancing the dust suppression efficiency and the environmental protection of the loading operation.

[0035] As a preferred embodiment, the support platform 11 includes a first support seat 111 and a second support seat 112. The material guide frame 131 is arranged above the second support seat 112. The second support seat 112 can be extended or shortened to drive the material guide frame 131 to rise or fall. It should be noted that the second support seat 112 adopts the existing structure. As long as it can drive the material guide frame 131 to rise or fall, the dynamic adjustment of the second support seat 112 can achieve precise matching of the output end height of the material guide unit 13 with the truck compartment to achieve better material distribution effect. At the same time, it can also avoid the impact dust caused by excessive drop to a certain extent, and reduce the spillage of materials during loading, and cooperate with the spray parts 135 on the surface of the material guide platform 132 to form a full process optimization of dust suppression.

[0036] On the other hand, the present application also proposes a method for loading silo materials, which adopts the aforementioned silo material loading structure and further includes the following steps: S1: Initial system setup and material transport start-up: park the truck in front of the support platform 11, adjust the height of the material guide unit 13 to match the truck compartment, and start the material conveyor 12 to transport gravel to the material guide platform 132 in the first operating state.

[0037] First, the truck to be loaded is parked in a pre-set position in front of support platform 11. Second support base 112 of support platform 11 is activated, and the height of guide frame 131 and guide unit 13 are adjusted to optimally match the height and depth of the truck compartment entrance to minimize material drop and optimize material coverage. Guide platform 132 is then confirmed to be in its first operating state. Simultaneously, material conveyor 12 is activated, and the gravel in the silo is continuously conveyed to the end of material conveyor 12, where it smoothly connects to the input end of guide platform 132, now in its first operating state. The gravel flows across the surface of guide platform 132, forming a layer. Fine stone powder accumulates near the bottom of the platform 132 due to gravity and vibration.

[0038] S2: Drive contraction to trigger spraying and backward distribution, start the driving mechanism 133 to drive the material guide platform 132 to switch to the second operating state, the telescopic plate 1321 contracts to move the material drop point backward to distribute the material to the rear of the truck compartment, and at the same time the second plate body 1342 compresses the first liquid storage chamber 1343 to trigger the dust suppression liquid to spray on the surface of the telescopic plate 1321 upward.

[0039] The drive mechanism 133 (e.g., a hydraulic cylinder) is activated, driving the material guide platform 132 from its first operating state to its second operating state. During this process, the cross frame 1322 is linked to cause the telescopic plates 1321 to retract. The second plate 1342 of each telescopic unit 134 slides into the first liquid reservoir 1343 of the first plate 1341 of its adjacent unit, shortening the overall length of the material guide platform 132 and changing its tilt angle. This shifts the drop point toward the rear of the truck compartment, causing gravel on the surface of the material guide platform 132 to primarily slide toward and accumulate in the rear half of the truck compartment. Simultaneously, the second plate 1342 slides into the first liquid reservoir 1343, compressing its volume and causing the pressure of the dust suppression liquid within the first liquid reservoir 1343 to increase dramatically. The high-pressure liquid acts on the spray element 135 at the liquid outlet 1344, overcoming the force of the internal spring 1352 and pushing the sealing ball 1353 apart. The dust suppression liquid is instantly and forcefully ejected through the spray channel 1354. The key point is that the spray part 135 located on the upper surface of the upper telescopic plate 1321 directly sprays the dust suppression liquid onto the stone powder enriched layer (dust source core area) close to the surface of the material guide platform 132, realizing instantaneous infiltration dust suppression; the spray part 135 located on the lower surface of the lower telescopic plate 1321 assists in suppressing environmental dust.

[0040] S3: The drive extends to stop spraying and forward distribution and replenish liquid, and the material guide platform 132 is driven to reset to the first operating state. The telescopic plate 1321 extends to move the material drop point forward to distribute the material to the front of the truck compartment, and at the same time, the dust suppression liquid is replenished through the one-way valve.

[0041] When the material guide platform 132 reaches the set second operating state, the piston end of the drive mechanism 133 (hydraulic cylinder) begins to retract, driving the material guide platform 132 from the second operating state to the first operating state. During this process, the cross frame 1322 reverses the linkage to extend each telescopic plate 1321. The second plate 1342 of each telescopic unit 134 slides out of the first liquid storage chamber 1343, causing the overall length of the material guide platform 132 to increase and the tilt angle to change again. The drop point moves toward the front of the truck compartment, causing the gravel on the surface of the material guide platform 132 to slide and accumulate primarily in the front half of the truck compartment. Simultaneously, as the second plate 1342 slides out, the volume of the first liquid storage chamber 1343 increases, the pressure rapidly decreases, and the spring 1352 in the spray element 135 pushes the sealing ball 1353 back to its original position, tightly sealing the inlet of the spray channel 1354 and stopping the spraying of dust suppression liquid. At the same time, under the action of the low pressure in the first liquid storage chamber 1343 and the one-way valve, the dust suppression liquid in the dust suppression liquid tank is replenished to each first liquid storage chamber 1343 through the first liquid supply pipe 1345, preparing for the next spraying.

[0042] S4: Repeat S2-S3 to form periodic swing distribution and synchronous spraying until the truck compartment is evenly loaded.

[0043] Steps S2 (driving contraction: spraying to suppress dust, moving the landing point backward, and distributing the material to the rear of the truck compartment) and step S3 (driving extension: moving the landing point forward, and distributing the material to the front of the truck compartment) are repeated periodically. The material conveyor 12 continuously feeds material, and the landing point of the material guide platform 132 automatically and regularly swings from front to back and then back to front in the truck compartment under the reciprocating action of the drive mechanism 133. The precise spraying of the dust suppression liquid (which only occurs in step S2 of the contraction process) is strictly limited to the key area at the bottom of the material guide platform 132 where stone powder is enriched, and the mechanical pressure generated by the structural movement is used to achieve efficient and low-energy dust suppression. Through the synergistic effect of this synchronized swinging distribution and fixed-point spraying, the gravel is able to form a highly uniform accumulation layer in the front-to-back direction of the truck compartment while the truck remains stationary. This cycle continues until the truck compartment loading meets the predetermined requirements, at which point the material conveying and the drive mechanism 133 are stopped, completing the efficient and low-dust silo material loading operation. If the dust suppression requirement is extremely high (eg, high fine powder content), the auxiliary nozzle 1347 of the second liquid storage chamber 1346 in the second plate 1342 can be activated simultaneously (continuously supplying liquid through the second liquid supply pipe 1348) to supplement dust suppression.

[0044] The present invention uses a drive mechanism 133 to periodically drive the guide table 132 between a first and second operating state. During this process, the length of the guide table 132 changes dynamically, causing its output end (the material drop point) to automatically and regularly swing from front to back and back again within the vehicle compartment while the truck remains completely stationary. This dynamic swinging material distribution mechanism completely solves the problem of traditional fixed guide belts relying on frequent truck shifting to achieve uniform material distribution across the front and back of the vehicle compartment, significantly improving loading efficiency. At the same time, in the key action of the material guide platform 132 converting from the first state to the second state, the second plate 1342 of the telescopic unit 134 synchronously compresses the first liquid storage chamber 1343, and uses the mechanical movement of the structure itself to generate high pressure, instantaneously triggering the spray part 135 to open, and spraying the dust suppression liquid directly and accurately onto the stone powder enriched layer (dust source core area) close to the surface of the upper telescopic plate 1321 (i.e. the bearing surface of the material guide platform 132). The dust suppression liquid does not need to penetrate the upper gravel and can quickly combine with the dust source, fundamentally solving the fundamental defects of traditional roof spray dust suppression liquid that is difficult to reach the bottom dust source and has poor dust suppression effect.

Any equivalent substitution or modification made by those skilled in the art based on the present invention is within the protection scope of the present invention.
