[0003] During the mixing process of the sintering material, the moisture content of the mixture is usually controlled in the range of 6.5-7.5% to meet the normal production requirements. In order to ensure that the moisture content of the mixture meets the control requirements and the production needs, the moisture content of the outlet belt of the mixer is usually manually observed and the sample is sent for inspection. The traditional sampling method is to directly grab the belt from the belt machine with gloves or to shovel the belt with a shovel, a bucket and other tools, which has the problems of non-standard sampling, poor safety and the like.

[0024] The technical solutions in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without any creative labor fall within the protection scope of the utility model.

[0025] As shown in Figure 1 and Figure 2 A preferred embodiment of the utility model provides a sampling device for sintering mixture, which takes out the sintering mixture from the working surface of the running belt through the receiving cylinder 2, the receiving chute 6, the receiving hopper 3 and the rotating mechanism.

[0026] The sampling device is used to be installed on one side of the sintering material conveying belt, and generally the receiving cylinder 2 is hinged on the large frame on one side of the belt conveyor or is hinged on the support 1, and then the support 1 is fixed on one side of the belt conveyor.

[0027] As shown in Figure 3 , Figure 4 The receiving cylinder 2 is in a cylindrical shape, one end of which is welded with the sealing plate 5 and is closed, and the other end is open. The discharge port 201 is formed on the bottom of the receiving cylinder 2 close to the sealing plate 5, the sintering material enters into the receiving cylinder 2 from the open end, then flows downwards along the space in the receiving cylinder 2 and finally comes out from the discharge port 201.

[0028] The receiving cylinder 2 can also be designed as a semi-open structure similar to a groove, and the groove forms a channel so that the sintering material flows downwards along the channel and finally comes out from the discharge port 201.

[0029] With reference to Figure 3 , the open end part of the receiving cylinder 2 in the embodiment extends outward, the cross-sectional shape of the outwardly extending part is a part of a circle, one side of the receiving hopper 3 is provided with the feeding port 301, and the side away from the feeding port 301 is welded with the outwardly extending part of the open end of the receiving cylinder 2, so that the receiving hopper 3 forms a semi-enclosed structure.

[0030] The top of the receiving hopper 3 is open, the side walls of the receiving hopper 3 on both sides of the feeding port 301 are inclined or vertical, and the space in the receiving hopper 3 gradually narrows from the outwardly extending part of the open end of the receiving cylinder 2 to the direction of the feeding port 301, similar to a bucket form. When taking the material, the side of the receiving hopper 3 with the feeding port 301 faces the material feeding direction of the belt conveyor, the feeding port 301 of the receiving hopper 3 is located at the middle part of the belt conveyor, the receiving hopper 3 is inclined to the working surface of the belt conveyor, and the mixed material of the part of the cross section of the material is taken out along the material conveying area on the upper surface of the belt conveyor. The taken material is the middle part of the sintering material on the belt conveyor, and thus is representative.

[0031] As Figure 1 shown, the bracket 1 adopts a profile, and has a groove at the top of the bracket 1, and a rotating shaft 7 is arranged in the groove, and the rotating shaft 7 is generally rotatably connected with the bracket 1 through a bearing, and the bottom of the receiving cylinder 2 close to the discharge port 201 is welded with the rotating shaft 7, so that the receiving cylinder 2 can rotate relative to the bracket 1 in the vertical plane.

[0032] In other technical solutions, the rotating shaft 7 can be fixedly welded on the bracket 1, and the bottom of the receiving cylinder 2 is rotatably connected with the rotating shaft 7 through a bearing.

[0033] A circular rod-shaped handle 4 is welded on the closed end of the receiving cylinder 2, i.e. the sealing plate 5, and the handle 4 also extends along the axial direction of the receiving cylinder 2, and the length of the handle 4 is slightly longer than the length of the receiving cylinder 2, so that the center of gravity of the receiving cylinder 2 and the handle 4 is towards the outside of the belt conveying line, i.e. away from the belt conveying line. In this way, in the natural state, one end of the receiving cylinder 2 with the handle 4 will be inclined downward, and one end of the receiving cylinder 2 with the receiving hopper 3 will be tilted upward, which will not hinder the normal work of the belt conveying line.

[0034] As Figure 1 , Figure 2 , in order to limit the inclination angle of the handle 4, a baffle 11 is welded on the top of the bracket 1, and the bottom of the baffle 11 has a semicircular groove which is matched with the shape of the receiving cylinder 2. When one end of the receiving cylinder 2 with the handle 4 is inclined downward, the baffle 11 matched with the semicircular groove can block and limit the receiving cylinder 2, so as to prevent the height of one end of the receiving cylinder 2 with the receiving hopper 3 from being too high when it is tilted upward.

[0035] A receiving chute 6 is arranged below the discharge port 201 of the receiving cylinder 2, and the receiving chute 6 is arranged in an inclined manner, and the upper end of the receiving chute 6 is welded on the bracket 1.

[0036] The receiving cylinder 2, the receiving hopper 3 and the handle 4 together form a non-transmission lever, and by using the principle of lever, the handle 4 is lifted, and one end of the receiving cylinder 2 with the receiving hopper 3 will move downward to the working surface of the belt conveyor, and the sintering material being conveyed on the belt conveyor will enter into the receiving hopper 3 from the feeding port 301 of the receiving hopper 3, then the handle 4 is pressed downward, and the receiving cylinder 2 and the receiving hopper 3 will be inclined downward at one end of the handle 4, and the sintering material in the receiving hopper 3 will flow along the inclined surface into the receiving cylinder 2, and then be discharged from the discharge port 201 and fall into the receiving chute 6 below, and finally flow into the storage tank below through the receiving chute 6. After the material is taken, one end of the receiving cylinder 2 with the handle 4 always remains in an inclined state under the action of gravity.

[0037] As Figure 4As shown, in order to facilitate the sinter in the receiving cylinder 2 to flow out completely, the discharge port 201 at the bottom of the receiving cylinder 2 extends to the position of the sealing plate 5, so that the sinter in the receiving cylinder 2 flows out along the discharge port 201 after being blocked by the sealing plate 5 during flowing downward.

[0038] The mixed material storage box is in a cylindrical or square shape, is connected to the oblique end surface of the receiving chute 6, and has a fixed tray below, so that the mixed material can be poured into a bag for inspection, or can be poured onto a belt conveyor after on-site visual inspection for recycling. Through the sampling device, the material can be easily, conveniently and safely taken, and the amount of about 500 grams of material taken on site can meet the detection and inspection.

[0039] The above technical solution only embodies the preferred technical solution of the technical solution of the present application, and some changes that the skilled in the art can make to some parts thereof embody the principles of the present application and are within the protection scope of the present application.
