Description

Technical Field

[0001] The invention relates to a conveyor, in particular to a vertical buried scraper conveyor for mining. Background Art

[0002] As an important equipment in my country's comprehensive mining face, the conveyor plays an important role in transporting coal and providing running channels for coal mining machines. Due to the narrow space of the mine, many large equipment are difficult to install, so they are forced to expand the excavation depth and width to place these equipment, resulting in unnecessary manpower and costs. Faced with this engineering problem, engineers usually improve and optimize the structure of mine equipment to make its structure as compact as possible and minimize the occupancy rate of mine space. However, the structure of some large equipment is special and irreplaceable. Neither structural optimization nor structural improvement can fundamentally change its structural principle, and the degree of volume reduction is also very limited. Therefore, in response to this working condition, a vertical buried scraper conveyor for mining is provided. Through its special structural design, coal can be transported vertically at a high speed with the lowest space occupancy rate. Summary of the invention

[0003] The purpose of this patent is to solve the problem that traditional large-scale mining equipment is difficult to install in the narrow space of the mine due to the particularity and irreplaceability of its own structure, and to provide a vertical mining buried scraper conveyor.

[0004] The scheme adopted by the present invention is:

[0005] A vertical mining scraper conveyor includes: a driving motor, a first wheel, a chain, a discharge port, a scraper, a feed port, a tail wheel, a shell, a guide plate, a reducer and a storage platform. The first wheel is a driving sprocket, which is installed on the storage platform behind the shell and is connected to the driving motor through the reducer. The first wheel drives a plurality of chains and a plurality of scrapers to perform closed motion. The tail wheel is a driven sprocket. The feed port is arranged on the right side of the shell, the discharge port is arranged below the shell, and the storage platform is welded to the rear of the shell.

[0006] As a further improvement of the present invention, the vertical buried scraper conveyor for mining is usually installed in a mine environment where the environment is narrow and requires a large angle or vertical lifting.

[0007] As a further improvement of the present invention, the sprocket has a length of 280 mm and a radius of 100 mm, with 5 sprocket teeth and chain pockets distributed at equal angles, and a tooth width and a tooth-to-tooth spacing of 36°.

[0008] As a further improvement of the present invention, 34 scrapers are evenly distributed in the shell, each scraper is 236 mm apart, and the length, width and height of the scraper are 300 mm, 30 mm and 20 mm respectively.

[0009] As a further improvement of the present invention, the housing contains two rows of chains, each row of chains is composed of two types of chain links, horizontal chains and vertical chains, and each row is distributed with 55 horizontal chains and vertical chains, with a spacing of 73 mm between each other.

[0010] As a further improvement of the present invention, the length, width and height of the shell are 550 mm, 300 mm and 1080 mm respectively.

[0011] As a further improvement of the present invention, the reducer is a DBY conical cylindrical gear reducer with a reduction ratio of 1:8.

[0012] As a further improvement of the present invention, the motor adopts a TYTB series permanent magnet synchronous motor.

[0013] As a further improvement of the present invention, the size of the feed port is 240 mm×200 mm, and the size of the discharge port is 280 mm×240 mm.

[0014] Compared with the current technology, the advantages of this patent are:

[0015] 1. The design concept of the present invention is same-side unloading, that is, the feed inlet and the discharge outlet are on the same side, so that the present invention has a compact structure and can be applied to a variety of working conditions.

[0016] 2. The housing of the present invention can flexibly adjust its conveying height according to different working conditions, further improving its vertical conveying capacity.

[0017] 3. The number of scrapers of the present invention can be flexibly adjusted according to the load of the conveying task and the parameter characteristics of the conveyed coal.

[0018] 4. The selection of the motor and reducer of the present invention takes dust prevention into consideration, thus avoiding the occurrence of malfunctions caused by direct contact between the power source and coal dust.

[0019] 5. The materials of the present invention are all wear-resistant and corrosion-resistant materials, so that the parts and the whole machine of the present invention have a long life cycle, saving the time and cost of workers' downtime maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings. The embodiments described in the present invention are only a small part of the embodiments of the present invention. Without the premise that ordinary technicians in this field have made creative work, other embodiments obtained also belong to the scope of protection of the present invention.

[0025] like Figure 1 A vertical buried scraper conveyor for mining is shown, wherein the storage platform 8.1 is welded to the rear of the shell 8, the first wheel 2 is a driving sprocket, installed on the storage platform 8.1 at the rear of the shell 8, and connected to the driving motor 1 through the reducer 10. The first wheel 2 drives a plurality of chains 3 and a plurality of scrapers 5 to perform closed motion, the tail wheel 7 is a driven sprocket, the feed port 6 is arranged on the right side of the shell 8, and the discharge port 4 is arranged below the shell 8.

[0026] In order to facilitate the maintenance of the shell 8, ordinary bolts are used to connect the plates to facilitate subsequent maintenance and replacement.

[0027] In order to achieve energy saving, green, safety and other requirements, the output speed of the drive motor can be adjusted by the frequency converter during the operation of the device.

[0028] The working principle of a vertical mining scraper conveyor is as follows: before the invention works, the on-site technicians should measure the placement position inside the mine, set the conveying parameters of the invention according to the measurement results and the heavy degree of the conveying task, and check the drive motor and the inside of the shell to ensure that the scraper is stably installed in the chain ring, the chain ring can be aligned with the sprocket teeth of the first and tail sprockets, and whether the sprockets rotate freely. The technicians can adjust the motor speed in real time according to the shape and size of the conveyed coal to keep it at a reasonable value. When the conveyor is started, the first wheel will rotate clockwise driven by the drive motor and reducer, and then drive the chain and scraper to form a rapid periodic motion. When the coal enters the shell from the inlet, it will fall to the bottom of the shell under the influence of gravity. With the continuous rotation of the tail wheel and the movement of the scraper, it will be lifted vertically from the left side of the shell. Due to the special structural design of the shell, the scraper and chain are just close to the inner wall and baffle of the shell, and the coal will not fall from mid-air. When it is transported to the head of the machine, the coal that loses the baffle effect will fall from the discharge port. This is the whole process of vertical transportation. The whole process is efficient and convenient. It not only completes the transportation task with the minimum space occupancy, but also realizes the vertical transportation of coal, providing a theoretical basis and guiding significance for the subsequent development of other vertical transportation equipment.

[0029] The parts used in the present invention are all standard parts commonly used in the market.

[0030] Although the embodiments of the present invention have been described, it is apparent to those skilled in the art that the embodiments described above can be upgraded, modified and varied based on the principles and structures of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
