The original lining plates have a short service life and each lining plate is fixedly connected by four bolts. This design brings great working difficulty and labor intensity to the maintenance work of replacing the lining plate of the receiving hopper, and has a high safety risk. At the same time, the cement receiving port of the heavy plate feeder has pits due to long-term wear by ore, and the internally inlaid steel rails also show wear. Its structure cannot be replaced and repaired, posing a great safety hazard. More importantly, if this problem persists for a long time, it will greatly extend the overall annual maintenance time, and there are double safety hazards for both staff and equipment, bringing great economic losses to the enterprise.

Specific embodiments

[0022] The present invention will be further described in detail below with reference to the accompanying drawings: This embodiment is implemented on the premise of the technical solution of the present invention, and specific implementation manners are given, but the protection scope of the present invention is not limited to the following embodiments.

[0023] Embodiment 1: As Figures 1-4 shown, a modular lining plate for the receiving hopper of a large-scale mine heavy plate feeder involved in this embodiment includes: a modular lining plate of the cement feed opening, a horizontal modular lining plate, a modular lining plate of the receiving hopper, a connecting bolt, and an alloy steel mother plate; the inside of the receiving hopper of the heavy plate feeder is divided into three parts from top to bottom: the cement feed opening part, the horizontal part, and the receiving hopper part; the upper bottom of the cement feed opening part and the lower bottom of the receiving hopper part have the same long side dimension as the horizontal part;

[0024] The alloy steel mother plate is fixed on the steel rail on the inner surface of the cement feed opening part, and the modular lining plate of the cement feed opening is fixed on the surface of the alloy steel mother plate by means of a sunk groove through the connecting bolt; the horizontal modular lining plate is fixed on the inner surface of the horizontal part; the modular lining plate of the receiving hopper is fixed on the inner surface of the receiving hopper part;

[0025] The modular lining plate of the cement feed opening includes a square lining plate 1 and a triangular lining plate 1, the alloy steel mother plate includes a square mother plate and a triangular mother plate, the square mother plate and the square lining plate 1 have the same shape and the size of the square mother plate is smaller than that of the square lining plate 1, the triangular mother plate and the triangular lining plate 1 have the same shape and the size of the triangular mother plate is smaller than that of the triangular lining plate 1; the horizontal modular lining plate includes a square lining plate 2, and the modular lining plate of the receiving hopper includes a square lining plate 3 and a triangular lining plate 2; the cement feed opening part and the receiving hopper part are frustum of a pyramid, so when the mother plate is first set and then the lining plate is set on the inner side of the cement feed opening part, the size of the mother plate is larger than that of the lining plate; also because each side of the frustum of a pyramid is a trapezoid, so the cement feed opening part and the receiving hopper part are provided with triangular lining plates, the horizontal part is a prism, so the lining plates inside the horizontal part are all square lining plates.

[0026] The modular liners of the cement feed opening part are connected by a "serrated" connection within each side, and the modular liners of the cement feed opening between two sides are connected by contact; the modular liners of the horizontal part are connected by contact within each side, and the modular liners of the horizontal part between two sides are connected by contact; the modular liners of the receiving hopper part are connected by a "serrated" connection within each side, and the modular liners of the receiving hopper between two sides are connected by contact. Compared with the original receiving hopper liner which has a "vertical seam" as a whole, the design of this utility model uses a "serrated" new connection form, fundamentally eliminating the serious wear at the surrounding joints of the liner during use due to the original design defect. Since the inner side of the frustum part is inclined and has a large contact area with the ore, a serrated connection is set between the liners to increase the stability of the contact part and extend the service life. The main function of the horizontal part is to guide the material, so the liners can be connected by contact.

[0027] This utility model relates to a modular liner for the receiving hopper of a heavy plate feeder in a large mine. The materials of the modular liners of the cement feed opening, the horizontal part, and the receiving hopper are all alloy steel surfacing plates with a thickness of 35 mm.

[0028] This utility model relates to a modular liner for the receiving hopper of a heavy plate feeder in a large mine. The alloy steel mother plate is an alloy steel surfacing plate with a thickness of 20 mm.

[0029] This utility model relates to a modular liner for the receiving hopper of a heavy plate feeder in a large mine. The connecting bolts are made of 8.8-grade countersunk high-strength bolts. There are 4 - 12 connecting bolts provided on the modular liners of the cement feed opening, the horizontal part, the receiving hopper, and the alloy steel mother plate. There are 8 - 12 connecting bolts provided on the square liner, and 4 - 8 connecting bolts provided on the triangular liner.

[0030] This utility model relates to a modular liner for the receiving hopper of a heavy plate feeder in a large mine. The alloy steel mother plate is fixed on the rails of the cement feed opening part. Among them, the rails in the middle area of the cement feed opening part are connected to the alloy steel mother plate by bolts, and the rails around the cement feed opening part and the alloy steel mother plate are fixed by welding.

[0031] The utility model discloses a modular liner for a receiving hopper of a heavy-duty plate feeder in a large mine. 3-5 liner plates are provided on each side of the cement feed port and the receiving hopper, and 2-3 liner plates are provided on each side of the transverse portion. Since the internal size of the receiving hopper of a heavy-duty plate feeder in a large mine is large, the modular liner must take into account convenience, increasing the area of a single liner plate as much as possible, thereby reducing the number of liners and reducing the difficulty of replacement. The weight of the liner plate must also be considered, and the area of a single liner plate cannot be increased blindly. The number of liners provided in this application has been verified by experiments, the weight of the liner plate is suitable for hoisting installation, and the number of liners is also convenient for replacement.

[0032] The utility model discloses a modular liner for the receiving hopper of a heavy-duty apron feeder in a large mine. A first triangular liner and a second triangular liner are respectively provided on the left and right sides of each side of the cement feed inlet and receiving hopper. The left and right sides of the liner of the cement feed inlet and receiving hopper are both triangular liner panels, with a square liner in the middle. The liner shapes are arranged as symmetrically as possible, resulting in fewer liner shapes and a smaller number of liner sizes compared to existing small liner panels. This makes liner fabrication and installation more convenient.

[0033] Example 2: Figures 1-4 As shown, the present embodiment involves a modular lining for a receiving funnel of a heavy-duty plate feeder in a large mine. On the basis of the cement material port of the original heavy-duty plate feeder receiving funnel, a layer of alloy steel mother plate is first fixed by welding and bolts, and then the modular liners of the cement material port are installed one by one on the mother plate by connecting bolts. In the subsequent maintenance work, the mother plate does not need to be replaced, only the liner is replaced; on the basis of the original heavy-duty plate feeder receiving funnel mother plate, the transverse modular liners and the receiving funnel grinding block liners are installed one by one by connecting bolts.

[0034] The modular liners used in the heavy-duty apron feeder hopper are symmetrical on both sides. During maintenance, workers use a 25-ton crane and related lifting tools to install all the liners in a modular manner on the hopper surface. When the liners reach the end of their service life, workers remove and install them in the same manner, which is convenient, efficient, safe, and saves time and effort.

[0035] After the implementation of this utility model in actual maintenance work, it not only fundamentally solves the drawback of the short service life of the original lining plate of the receiving hopper, but also fundamentally avoids the problems of high safety risks, high labor difficulty and intensity for workers during the process of replacing the lining plate of the receiving hopper of the heavy-duty plate feeder. It also replaces the new modular lining plate in a safe, orderly, efficient and convenient manner. At the same time, the new modular lining plate provides more comprehensive protection for the cement foundation, reduces the repair of the guide rail, fundamentally solves the wear problems of cement and steel rails at the cement receiving port of the heavy-duty plate feeder in the ore storage pile, realizes the large size of the surfacing plate, shortens the maintenance and replacement time, strengthens the protection of the cement foundation at the material port, and extends the service life of the foundation.

[0036] The above are only the preferred specific embodiments of the present utility model. These specific embodiments are all different implementation manners based on the overall concept of the present utility model, and the protection scope of the present utility model is not limited thereto. Any changes or replacements that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
