Description

Technical Field

[0001] This utility model belongs to the field of coal mine tunneling and transportation technology, specifically relating to a scoop-type material guide device to prevent coal from deviating from its designated path. Background Technology

[0002] During bottom-extraction tunneling operations, a significant problem frequently arises after the rock cutting work (involving rock tunnel sections): rock pile-up easily occurs in the area 5 to 10 meters behind the unit and the belt conveyor. The root causes of this problem are complex and varied, but the core factors can be summarized into two points: First, during transport, the rock may bounce up and fall into an unexpected area due to deviation from the landing point of the transfer belt; second, belt misalignment during operation may cause rock to spill off the belt and fail to fall accurately within the effective carrying capacity of the belt conveyor. This off-track rock not only increases the difficulty of cleaning the working face but also forces workers to frequently adjust the belt position, severely impacting the efficiency and safety of the tunneling operation.

[0003] In view of the above situation and in combination with the specific characteristics of the tunneling operation environment on site, this utility model proposes an innovative solution - namely, to design and apply a scoop-type material guiding device to prevent the falling coal (gangue) from deviating. Utility Model Content

[0004] This invention aims to solve the problem that when the center point of the waste rock falls off the conveyor belt, the waste rock bounces up and falls instantly, failing to land accurately on the conveyor belt.

[0005] This utility model provides the following technical solution: a scoop-type material guiding device to prevent coal from deviating from its designated path, comprising two material guiding components, one on the left and one on the right; the two material guiding components are installed on the left and right sides of the transfer belt.

[0006] The material guiding assembly includes a bracket and anti-deviation baffles. The bracket is fixed on the belt frame of the transfer belt, and the anti-deviation baffles are installed on the bracket. The anti-deviation baffles on the left and right sides of the material guiding assembly are located on the left and right sides of the waste drop point of the transfer belt. The anti-deviation baffles on the left and right sides form a material guiding channel that is wider at the top and narrower at the bottom.

[0007] Furthermore, the upper end of the anti-deviation baffle is hinged to the bracket, and a limiting mechanism for adjusting the tilt angle of the anti-deviation baffle is provided between the anti-deviation baffle and the bracket.

[0008] Furthermore, the limiting mechanism includes a control rod, the upper end of which is hinged to an anti-deviation baffle. Limiting nodes are distributed at intervals along the length of the control rod, and the bracket is provided with locking positions for locking the limiting nodes.

[0009] Furthermore, the control rod has serrations distributed on it, which serve as limit nodes. A clamping plate is fixed on the bracket, and the serrations on the control rod can be clamped onto the clamping plate to diagonally support the anti-deviation baffle.

[0010] Furthermore, the support includes upper and lower crossbeams, which are connected by two longitudinal beams, and an anti-deviation baffle is located between the two longitudinal beams.

[0011] Furthermore, the card plate is located below the anti-deviation baffle.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] This utility model provides a scoop-type material guiding device to prevent coal from deviating from its designated path. The overall structure consists of two sections, left and right, with an ingenious design and a simple, clear frame construction. The scoop's dimensions have a high tolerance for error, ensuring manufacturing flexibility and practicality. The installed frame is not only structurally stable and reliable but also easy to disassemble and maintain. The dimensions of the connecting rods and the frame are welded according to the actual conditions of the on-site coal gangue removal equipment, ensuring high adaptability. Equipped with an adjusting rod, this utility model can precisely control the landing point of the coal gangue, ensuring it falls accurately onto the belt conveyor, thereby greatly reducing the occurrence of coal gangue falling directly onto the bottom plate and effectively improving the efficiency and safety of coal gangue transportation.

[0014] After adopting the coal-falling anti-deviation scoop, the gangue can fall accurately onto the belt conveyor. This improvement not only greatly reduces the scattering of gangue, but also frees up the personnel who previously needed to clean up the gangue, allowing them to devote their time and energy to other more important construction operations.

[0015] From an economic perspective, this improvement also brings significant benefits. Considering that the labor cost is approximately 160 yuan per person per day, and a three-shift work system is implemented daily, the total annual labor cost would reach 175,200 yuan (i.e., 160 yuan / person × 3 people × 365 days). After adopting this utility model, it is estimated that this labor cost for cleaning gangue can be saved annually, bringing direct economic benefits of approximately 175,200 yuan to the enterprise.

[0018] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0019] like Figure 1 The diagram shows a scoop-type material guiding device to prevent coal from deviating from its designated path. It includes two guiding assemblies, left and right, installed on the left and right sides of a transfer conveyor belt. Each guiding assembly includes a support 1 and anti-deviation baffles 2. The support 1 is fixed to the belt frame 3 of the transfer conveyor belt, and the anti-deviation baffles 2 are installed on the support 1. The anti-deviation baffles 2 on the left and right guiding assemblies are located on the left and right sides of the coal drop point on the transfer conveyor belt, forming a guiding channel that is wider at the top and narrower at the bottom. This device effectively controls the coal conveying path, ensuring that the coal falls accurately onto the conveyor belt and is then smoothly transported to the coal bin. The application of this device not only significantly reduces coal accumulation but also greatly improves the overall visual environment of the working face, enhances the safety standardization level of the work site, and provides strong support for the efficient and safe operation of coal mine tunneling and transportation.

[0020] The upper end of the anti-deviation baffle 2 is hinged to the support 1. An adjustable limiting mechanism for the tilt angle of the anti-deviation baffle 2 is provided between the anti-deviation baffle 2 and the support 1. The tilt angle of the anti-deviation baffle 2 can be adjusted to change the outlet width of the material guide channel. The landing point of the coal gangue is precisely controlled so that it falls accurately onto the belt conveyor, thereby greatly reducing the occurrence of the coal gangue falling directly onto the bottom plate and effectively improving the efficiency and safety of coal gangue transportation.

[0021] The limiting mechanism includes a control rod 4, the upper end of which is hinged to the anti-deviation baffle 2. Limiting nodes 5 are distributed at intervals along the length of the control rod 4, and the bracket 1 is provided with a locking position for locking the limiting nodes 5.

[0022] The control lever 4 has serrations, which serve as limit nodes 5. A clamping plate 6 is fixed on the bracket 1. The clamping plate 6 is located below the anti-deviation baffle 2. The serrations on the control lever 4 can be clamped on the clamping plate 6 to support the anti-deviation baffle 2.

[0023] The support 1 includes two horizontal beams 1.1, which are connected by two longitudinal beams 1.2. The anti-deviation baffle 2 is located between the two longitudinal beams 1.2.

[0024] A spray dust removal system can be installed on the upper support 1 to ensure the stability and dust removal effect of the entire device, providing a solid foundation for subsequent gangue transportation.

[0025] This coal-falling anti-deviation sieve is constructed from a welded iron frame and sheet metal, featuring an innovative left-right dual-panel design. This simple frame structure offers greater tolerance for dimensional errors during machining, reducing processing difficulty and cost. The dimensions of the support frame 1 and the anti-deviation baffle 2 can be customized by welding according to the on-site coal removal equipment, ensuring that the support frame 1 is sturdy, reliable, and easy to disassemble after installation, allowing for rapid adaptation to different on-site environments and equipment requirements.

[0026] During the waste rock discharge process, the operator can precisely control the direction of the waste rock falling by operating the control lever 4, so that the waste rock falls accurately onto the belt conveyor, effectively reducing the occurrence of waste rock falling to the bottom plate, improving waste rock discharge efficiency, and reducing subsequent cleaning work.

[0027] This device is highly versatile and can be integrated with various equipment. It can be customized on-site to fit the real-time conditions of the integrated equipment, effectively limiting the spillage of gangue. This solves the problem of standardizing on-site operations, avoids wasting manpower, and achieves an efficient and environmentally friendly gangue removal operation mode.
