[0002] In the iron front system of the steel joint enterprise, sinter is one of the main raw materials of blast furnace, and after being produced in the sintering plant, it is generally transported by belt into the blast furnace raw material bin. A vibrating screen is arranged directly below the bin, and the sinter flows uniformly to the screen surface through the feeder below the bin, and the small particle size sinter that does not meet the requirements of the blast furnace (generally controlled below 5mm in process) is screened out after passing through the screen surface, and the screened material is the sinter that meets the requirements of the blast furnace particle size and enters the weighing tank (the end of the vibrating screen and the upper part of the weighing tank are both placed in a dust removal box). In order to ensure the quality of the sinter, a sampling device is used to sample the finished sinter.

[0003] CN210293739U discloses a kind of blast furnace sinter manual quick sampling device, including sampling hopper, sample hopper bracket, blanking baffle, sliding rail, support, the support is provided with sliding rail, the sample hopper bracket is set on sliding rail and can move horizontally before and after along sliding rail, the sampling hopper is set on sample hopper bracket, the bottom surface of sampling hopper is high in front and low in back, and the rear end of sampling hopper is provided with discharge port, and the discharge port is provided with movable blanking baffle.The utility model has the characteristics of low cost, simple structure, reasonable design and strong practicality, and can manually sample and test sinter, effectively improving production efficiency.

[0004] However, the above-mentioned device needs to be manually operated by the staff to sample the sinter when sampling, which is not convenient to operate, and the sinter will splash when the sinter collides with the sampling device during sampling. To solve the above problems, a sinter sampling device is proposed. UTILITY MODEL CONTENTS

[0005] The utility model aims to provide a kind of sinter sampling device, to solve the problem that staff needs to manually operate sampling device to sample, and sinter collides with sampling device when sampling, which can reduce the service life of the device.

[0006] To achieve the above objectives, the basic solution provided by this utility model is as follows: a sintered ore sampling device, comprising a feeding funnel and a sampling tube. The feeding funnel is equipped with conveying mechanisms at its top and bottom. The sampling tube passes through the outlet of the feeding funnel. A rotating annular indexing plate and a slewing bearing are respectively sleeved on both sides of the sampling tube. The rotating annular indexing plate and the slewing bearing are fixedly installed on the side wall of the feeding funnel by bolts. A connecting flange plate is fixedly installed on the sampling tube, and the connecting flange plate is connected to the rotating annular indexing plate by bolts. The rotating end of the scale is fixedly connected, and the driving end of the rotating annular scale is fixedly connected to a first motor. The sampling tube is fixedly connected to a mounting plate at one end near the slewing bearing. The mounting plate is fixedly connected to the rotating end of the slewing bearing by bolts. The sampling tube has a sampling port. A rotating shaft is rotatably connected inside the sampling tube. A spiral blade is sleeved on the rotating shaft. A discharge funnel is fixedly installed on one side of the sampling tube. A second motor is fixedly installed on the side wall of the mounting plate. The output end of the second motor is fixedly connected to the end of the rotating shaft.

[0007] The principle and beneficial effects of this utility model are as follows: The output end of the first motor drives the rotating annular indexing plate to work, and the connecting flange plate connected to it drives the sampling tube to rotate under the combined action of the mounting plate and the slewing bearing, so that the sampling port of the sampling tube is directly above. The sinter falling from above is sampled by the sampling port of the sampling tube. The output end of the second motor drives the rotating shaft to rotate, and the rotating shaft drives the spiral blade to rotate, which transports the sample sampled from the sampling port out and discharges it from the discharge funnel set at the end of the sampling tube and collects it. After the sampling is completed, the second motor stops working, and the first motor drives the rotating annular indexing plate to work, and the connecting flange plate connected to it drives the sampling tube to rotate in the opposite direction under the combined action of the mounting plate and the slewing bearing, so that the sampling port of the sampling tube is directly below. The second motor drives the spiral blade to rotate in the opposite direction through the rotating shaft, so that the sinter in the sampling tube is discharged from the sampling port. The sampling is convenient and the operation is simple.

[0008] Option 2, a preferred embodiment of the basic option, features guide plates symmetrically fixedly installed on both sides of the sampling port of the sampling tube. These guide plates facilitate the introduction of sintered ore into the sampling port.

[0009] Option 3, a preferred embodiment of the basic option, involves a conical baffle installed on the back of the sampling port of the sampling tube. Both ends of the conical baffle are fixedly connected to the back of corresponding guide plates. This conical baffle ensures that falling sinter impacts the sampling tube, reducing erosion and protecting it.

[0010] Option 4, a preferred embodiment of the basic option, involves providing a placement slot in the material guide funnel for housing the conveying mechanism. The output end of the conveying mechanism is placed within the placement slot, thus embedding the conveying end of the conveying mechanism within the material guide funnel.

[0011] In scheme five, which is a preferred scheme of the base scheme, the material guiding hopper is provided with an opening at the bottom of the side far from the placing groove. The opening is arranged to facilitate the conveying of the sinter to the conveying mechanism below the material guiding hopper, so as to avoid the accumulation of the sinter.
