Description

Technical Field

[0001] This utility model relates to the technical field of highway construction equipment, specifically to the anti-blocking material placement port of a stone material placement device for highway construction. Background Technology

[0002] Highway engineering refers to the surveying, measurement, design, construction, maintenance, and management of highway structures. Highway structures include roadbeds, pavements, bridges, culverts, tunnels, and other facilities. In highway maintenance and construction, paving is a crucial step in the formation of the pavement structure, involving a refined process and multi-machine collaborative operation. After paving, materials such as crushed stone need to be spread on the paved base layer to improve the pavement's load-bearing capacity and durability. The process of spreading crushed stone requires the use of a stone spreading device, which is a key piece of equipment for evenly laying stone materials.

[0003] Common aggregate spreading devices mainly include self-propelled spreaders and suspended spreaders. Suspended spreaders are often used in conjunction with asphalt distributors to form an asynchronous aggregate seal construction system. The modular design facilitates quick assembly and disassembly. During spreading, aggregate is poured in through the top storage port and the internal storage space. As the suspended vehicle or drive structure moves along the road surface, the aggregate is then evenly spread out through the bottom discharge port to form a uniform aggregate layer on the base surface.

[0004] The aforementioned aggregate placement device typically uses a flattened opening at the bottom discharge port to ensure uniformity in the aggregate spreading process. However, due to the excessive flatness of the bottom discharge port, the outlet gap is narrow. If there are water stains or other issues among the aggregate, localized condensation can easily occur at the discharge port, causing blockage. This affects the uniformity of aggregate spreading and normal use of the entire process, impacting the quality of base course construction and requiring subsequent repairs, thus increasing workload. Therefore, we propose an anti-blockage discharge port for aggregate placement devices used in highway construction. Utility Model Content

[0005] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0006] The purpose of this utility model is to provide an anti-blocking material placement port for a stone placement device used in highway construction, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an anti-blocking material placement port for a gravel placement device used in highway construction, comprising a main body, a material placement mechanism inside the main body, the material placement mechanism including a material placement cavity, and a ramp frame on one side of the inner wall of the material placement cavity, a hydraulic drive assembly fixed to the outer wall of the ramp frame, a telescopic groove inside the ramp frame, a hydraulic telescopic rod fixed to one end of the inner wall of the telescopic groove, an auxiliary push plate fixed to one end of the hydraulic telescopic rod, sliding grooves on both sides of the bottom surface of the auxiliary push plate, a discharge frame fixed to the bottom end of the material placement cavity, baffles fixed to both ends of the discharge frame, and a diversion plate fixed to the outer wall of the discharge frame.

[0008] Furthermore, the fabric cavity is opened around the inner wall of the main body, and the interior of the fabric cavity is formed into an integral funnel shape by a ramp frame.

[0009] Furthermore, the hydraulic telescopic rod is connected to the hydraulic drive assembly, and the auxiliary push plate forms a telescopic structure with the ramp frame through the hydraulic telescopic rod.

[0010] Furthermore, the bottom surface of the auxiliary push plate is in contact with the inner wall of the ramp frame, and the auxiliary push plate slides against the inner wall of the ramp frame through the sliding grooves on both sides of the bottom surface.

[0011] Furthermore, the bottom end of the fabric cavity is connected to the discharge rack, and the diverter plates are arranged at equal intervals along the outer wall of the discharge rack.

[0012] Furthermore, the main body includes a fabric frame, and a bolt mounting bracket is fixed to the inner wall of the fabric frame. A pivot bracket is fixed to one side of the top of the fabric frame, and a top cover is connected to one side of the pivot bracket.

[0013] Furthermore, the top cover forms a rotating structure with the top of the fabric frame via a rotating shaft bracket, and the fabric frame is welded and fixed to the bolt mounting bracket.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The anti-blockage feeding port is formed by the feeding frame and the feeding cavity inside. Crushed stone chips can be discharged through the discharge rack connected to the bottom of the feeding cavity. At the same time, the inclined structure of the ramp frame can keep the stone material sliding continuously. When the discharge rack outlet is blocked, the hydraulic telescopic rod can be used to drive the auxiliary push plate to extend and retract, so that the auxiliary push plate in the ramp frame can be pushed along the angle of the discharge rack to clear the blockage, thereby ensuring the stability and continuous operation of the spreading process and maintaining the uniformity of the bottom discharge.

[0016] This anti-clogging material spreading port is fixedly welded to the material spreading frame and bolt mounting bracket. This allows the material spreading frame to be easily combined with a driven vehicle or asphalt paving device via the bolt mounting bracket. The device is then driven by wheeled equipment to spread the gravel. The top of the material spreading frame is sealed with a top cover connected by a swivel bracket, which prevents rainwater from entering the cavity and causing dampness and blockage during external operations, thus reducing such situations and maintaining stable stone quality.

[0025] It should be noted that the terms "a" and "a plurality of" used in this disclosure are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0026] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] This utility model provides, for example Figure 1-4 The anti-blocking feeding port of the stone feeding device for highway construction shown includes a main body 1. The main body 1 has a feeding mechanism 2 inside. The main body 1 includes a feeding frame 101, and a bolt mounting bracket 102 is fixed to the inner wall of the feeding frame 101. A rotating shaft bracket 103 is fixed to one side of the top of the feeding frame 101, and a top cover 104 is connected to one side of the rotating shaft bracket 103.

[0028] To ensure stable use of this anti-clogging fabric inlet during the application of crushed stone, such as Figure 1 As shown, this anti-clogging material spreading port is fixedly welded to the material spreading frame 101 and the bolt mounting bracket 102, so that the material spreading frame 101 can be easily combined with the driven vehicle or asphalt paving device through the bolt mounting bracket 102. The device is driven by the wheel equipment to spread the mobile crushed stone. The top of the material spreading frame 101 is sealed by the top cover 104 connected by the swivel bracket 103, which can prevent rainwater from entering the cavity and causing moisture blockage during external operation, reduce such situations, and maintain the stability of the stone quality.

[0029] like Figure 2-4 As shown, the fabric feeding mechanism 2 includes a fabric feeding cavity 201, and a ramp frame 202 is provided on one side of the inner wall of the fabric feeding cavity 201. A hydraulic drive assembly 203 is fixed on the outer wall of the ramp frame 202. A telescopic groove 204 is provided inside the ramp frame 202, and a hydraulic telescopic rod 205 is fixed at one end of the inner wall of the telescopic groove 204. An auxiliary push plate 206 is fixed at one end of the hydraulic telescopic rod 205. Sliding grooves 207 are provided on both sides of the bottom surface of the auxiliary push plate 206. A discharge frame 208 is fixed at the bottom end of the fabric feeding cavity 201. Baffles 209 are fixed at both ends of the discharge frame 208, and a diversion plate 210 is fixed on the outer wall of the discharge frame 208.

[0030] To ensure the stability of the gravel spreading process, such as Figure 2-4As shown, this anti-clogging feeding port is formed by the feeding frame 101 and the feeding cavity 201 inside. Crushed stone chips can be discharged through the discharge rack 208 connected to the bottom of the feeding cavity 201. Simultaneously, the inclined structure of the ramp frame 202 maintains the continuous downward flow of the stones. When the outlet of the discharge rack 208 becomes blocked, the auxiliary push plate 206 can be extended or retracted in conjunction with the hydraulic telescopic rod 205. The hydraulic drive assembly 203 driving the hydraulic telescopic rod 205 consists of a gear pump, hydraulic oil, and an integrated oil circuit. After the hydraulic oil is pressurized and output, the flow direction and pressure of the oil are regulated by the integrated oil circuit and hydraulic control valve group. The high-pressure oil enters the hydraulic telescopic rod 205, which pushes the piston rod to make linear reciprocating motion, thereby outputting mechanical thrust or pull. This type of hydraulic drive process is a conventional technology and will not be described in detail here. The hydraulic telescopic rod 205 causes the auxiliary push plate 206 in the inclined frame 202 to be pushed along the angle of the discharge frame 208 to clear the blockage, thereby ensuring the stability and continuous operation of the spreading process and maintaining the uniformity of the bottom discharge.

[0031] During the process of spreading crushed stone, the above-mentioned material rack 208 can distribute the scattered crushed stone through the multi-component diversion plates 210 that are equidistantly arranged and fixed on the inner wall of the material rack 208, so as to ensure the uniformity of the crushed stone spreading. At the same time, the baffles 209 at both ends can ensure the spreading range and prevent crushed stone from overflowing onto the road, thus avoiding waste of resources.

[0032] In summary, when using this anti-clogging material inlet, the user first connects the material distribution chamber 201 to the drive equipment via the bolt mounting bracket 102 on the outer wall of the material distribution frame 101. Then, the crushed stone material is placed into the material distribution chamber 201, and the top cover 104 is placed on top. Subsequently, the drive equipment, such as an asphalt paver, carries this device along the road base, and the crushed stone is evenly discharged along the bottom discharge frame 208. When the outlet is blocked, its hydraulic telescopic rod 205 is driven, which drives the auxiliary push plate 206 connected to the bottom end to push along the ramp frame 202, pushing out the blocked crushed stone to achieve the purpose of clearing the blockage. Then, the normal spreading process can proceed.

[0033] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in the embodiments of this disclosure is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in the embodiments of this disclosure.
