Among them, half of the fixing plate is fixed on the mother board and the lining plate through the opening device, and the other half of the fixing plate is fixed on the body of the chute of the large grinding equipment through the tightening device and the fixing rod.

[0026] The present utility model relates to a new integrated lining plate for the chute of large-scale grinding equipment. The materials of the mother plate and the lining plate are both alloy steel surfacing plates with a thickness of 35 mm. The mother plate is arranged at the bottom of the equipment chute, and the lining plate is fixedly connected to the upper surface of the mother plate through a sunk groove. When the new integrated lining plate is closed, the mother plate is arranged at the bottom of the equipment chute, and the lining plate is arranged inside the chute. When the 35-mm-thick lining plate is worn thin, it needs to be replaced.

[0027] The present utility model relates to a new integrated lining plate for the chute of large-scale grinding equipment. The hinge is made of high-strength alloy steel plate. According to the size of the equipment chute, 1-5 hinges are equidistantly arranged on one side of the equipment chute. Generally, two hinges are arranged on each side. When the bottom size of the chute is large, and the sizes of the lining plate and the mother plate are also large, adding hinges can increase the stability of opening and closing.

[0028] The present utility model relates to a new integrated lining plate for the chute of large-scale grinding equipment. The bolts of the tightening device are made of 8.8-grade high-strength bolts.

[0029] The present utility model relates to a new integrated lining plate for the chute of large-scale grinding equipment. The bolts of the opening device are made of 8.8-grade high-strength bolts. According to the pressure borne by the new integrated lining plate in the closed state, through multiple tests, 8.8-grade high-strength bolts are selected.

[0030] The present utility model relates to a new integrated lining plate for the chute of large-scale grinding equipment. The size of the mother plate is greater than or equal to the size of the bottom of the large-scale grinding equipment chute, and the size of the lining plate is smaller than that of the mother plate. The mother plate needs to completely cover the bottom of the equipment chute, so the size of the mother plate needs to be greater than or equal to the size of the chute bottom. The lining plate is fixed on the mother plate by means of a sunk groove, so the size around the two lining plates combined is smaller than that of the two mother plates combined. The size of each lining plate can be specially designed according to the size of the grinding chute, and the alloy surfacing plates are installed at both ends of the chute in a "hinged door" manner to achieve the purpose of completely covering the chute.

[0031] The present utility model relates to a new integrated lining plate for the chute of large-scale grinding equipment. The quantities of the tightening device, the opening device and the fixing plate are adjusted according to the size of the mother plate and the material and weight of the substances passing through the grinding equipment chute.

[0032] The present utility model relates to a new integrated lining plate for the chute of large-scale grinding equipment. The fixing plates on the upper and lower sides of the mother plate are arranged at one-fifth of the distance from the gap where the mother plate and the lining plate are in contact. According to the content of the previous item, when a fixing plate is arranged on both the upper side and the lower side of the mother plate, the position of the fixing plate is set at one-fifth of the distance from the contact gap above or below the mother plate or the lining plate.

[0033] Example 2: As Figures 1 - 3As shown in the figure, a new integrated lining plate for the chute of large-scale grinding equipment involved in this embodiment is installed at the position of the chute of the original grinding equipment. First, the integrated alloy surfacing plate is installed on the edge of the chute through a hinge, and the principle is the same as that of opening and closing a door.

[0034] When installing the new integrated lining plate, select the sizes of the mother plate and the lining plate according to the size of the equipment chute. Fix the two mother plates on both sides of the bottom of the equipment chute through hinges respectively. The lining plate is fixed on the upper surfaces of the two mother plates in the way of sunk grooves. Then, at the upper and lower fixing positions on the lower surface of the mother plate, and at the gap where the two mother plates are joined, fix the fixing plate through the tightening device and the opening device, and the tightening device and the opening device are respectively arranged on the two plates; fix one end of the fixing rod on the equipment body, fix the fixing plate through the tightening device at the other end of the fixing rod, and then fix the other half of the fixing plate on the mother plate through the opening device.

[0035] After the installation is completed, it can enter the use stage. Lift the thickness of the maintenance lining plate. The initial thickness of the lining plate is 35mm. When the thickness of the lining plate is reduced by 10mm, it needs to be replaced. At this time, loosen the bolts of the opening device, and the mother plate opens downward. A little ore powder may fall, but the sizes of most ores are large and stuck in the ore storage pile and the receiving hopper. Replace the lining plate. After the replacement is completed, close the mother plate and fix the mother plate through the bolts of the opening device, thus completing the replacement work.

[0036] After the implementation of the present utility model in actual maintenance work, it not only fundamentally solves the drawbacks of the lining plate design sold in the existing market, but also fundamentally avoids the problems of high safety risks, high labor difficulty and high labor intensity for workers during the process of replacing the lining plate of the receiving hopper chute of the lowest-layer heavy plate feeder.
