[0003] When using the reducing iron fine material grinding device, an automatic feeding machine is usually configured to continuously add reducing iron fine material to the grinding device. However, there is a height difference between the docking part of the current many feeding equipment and the grinding equipment. Because the reducing iron fine material is small in volume and light in weight, if the instantaneous wind blows through during the feeding process, the flow trajectory of the reducing iron fine material flowing to the grinding equipment can be easily deviated, and then part of the reducing iron fine material can fall to the ground. This situation not only increases the workload of cleaning the fallen reducing iron fine material in the later period, but also can affect the production efficiency and product quality.

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0025] Please refer to Figures 1-6 The present application provides the following technical solutions: a reduced iron fine material grinding device, comprising a grinder 1, the output end of the grinder 1 is connected to the output end of a driving motor 2 through a belt, a feeding port 3 is installed on the side of the grinder 1 away from the output end, a discharging port 4 is installed on one side of the grinder 1, a guide rod 5 is installed on the outer wall of the feeding port 3;

[0026] When in use, the feeding port 3 of the grinder 1 is aligned with the discharging end of the feeder, the feeding hopper of the feeder is filled with the crushed small iron blocks, the discharging port 4 of the grinder 1 is connected with the recycling device, the driving motor 2 drives the grinder 1 to work, the feeder stably feeds the crushed small iron blocks into the grinder 1, the small iron blocks are sent into the crushing cavity of the grinder 1 through the feeding port 3 for crushing treatment, and the treated iron powder is recycled by the recycling device.

[0027] The outer wall of the guide rod 5 movably sleeves the sheath 6, the open end of the sheath 6 movably installs the movable sleeve 7, the bottom of the sheath 6 is fixedly installed with the U-shaped frame 8, the bottom of the U-shaped frame 8 is fixedly installed on the backing plate 9, one end of the backing plate 9 is movably installed on the vertical plate 10, and the bottom of the vertical plate 10 is fixedly installed on the mounting frame of the grinder 1 in a threaded structure.

[0028] Preferably, three longitudinal guide grooves 61 are formed at equal intervals in the inner wall of the sheath 6, and one longitudinal first sliding groove 62 is formed in the inner wall of each of the two sides of the open end of the sheath 6, and a first fixed plate 63 is fixedly installed at the bottom end of the inner wall of each first sliding groove 62, and a spring 64 is fixedly connected to the bottom of the first fixed plate 63.

[0029] When the sheath 6 moves, the guide grooves 61 move on the outer wall of the guide rod 5, so that the sheath 6 can stably move on the outer wall of the feeding port 3, thereby preventing misalignment.

[0030] A second sliding groove 71 is formed in the inner wall of each of the two sides of the movable sleeve 7, and a second fixed block 72 is fixedly installed at the top end of the inner wall of each second sliding groove 71.

[0031] When the sheath 6 drives the movable sleeve 7 to move, when the bottom of the movable sleeve 7 contacts the discharging end of the feeder, the sheath 6 continues to rise at this time, and the resistance received by the movable sleeve 7 becomes more and more obvious, so that the movable sleeve 7 stops at the current position, and the rising of the sheath 6 drives the first fixed plate 63 at the bottom to move, and the first fixed plate 63 moves to press the spring 64, so that the sheath 6 can independently move upward, thereby effectively covering the discharging end of the feeder.

[0032] One side of the first fixed plate 63 is movably inserted into the second sliding groove 71, one side of the second fixed block 72 is movably inserted into the first sliding groove 62, and the spring 64 is arranged between each group of first fixed plates 63 and second fixed blocks 72.

[0033] Preferably, the side, where the backing plate 9 and the vertical plate 10 are connected, of the backing plate 9 is fixedly connected with a sliding block 91, the other side of the sliding block 91 is fixedly connected with a sliding plate 92, a threaded bolt 93 is threadedly penetrated through one side of the sliding plate 92, and one end of the threaded bolt 93 is threadedly connected to the inside of a threaded groove 94.

[0034] When adjusting the pad plate 9, first make the bolt 93 contact with the butt joint structure of the threaded groove 94, so that the sliding plate 92 can be moved by the bolt 93, and when the sliding plate 92 moves, the pad plate 9 can be adjusted in height by the sliding block 91. When the height adjustment of the pad plate 9 is completed, the bolt 93 is screwed into the corresponding threaded groove 94, so that the pad plate 9 can be fixed at the adjusted height.

[0036] In specific use, when the grinding machine 1 is used, firstly, the feeding port 3 on one side of the grinding machine 1 is accurately aligned with the bottom of the discharge end of the small metal iron block feeding machine to ensure the smoothness of material transmission. Then, the discharge port 4 of the grinding machine 1 is tightly connected with the iron powder recycling equipment to ensure that the ground iron powder can be recycled in time and effectively.

[0037] However, in actual operation, there may be a large gap between the feeding port 3 and the discharge end of the feeding machine, which may affect the smooth falling of small iron metal into the feeding port 3. In order to solve this problem, the adjustable pad plate 9 and the sheath 6 are designed. The specific operation method is as follows:

[0038] The operator can smoothly and easily slide the pad plate 9 upward along the outer wall of the vertical plate 10. With the rising of the pad plate 9, it drives the sheath 6 to rise synchronously through the transmission action of the U-shaped frame 8. The continuous upward movement of the sheath 6 gradually fills and tightly covers the gap between the feeding port 3 and the discharge end of the feeding machine, which is like building a stable bridge for small iron metal, so that it can smoothly fall into the feeding port 3 along the predetermined track without worrying about being disturbed by external factors such as wind and deviating from the direction, or even falling to the ground.

[0039] In summary, by introducing the adjustable pad plate 9 and the sheath 6 mechanism, the accuracy and stability of the feeding port 3 in the feeding process are significantly improved, so that the small metal iron block can be efficiently and accurately fed into the grinding machine 1 for processing.

[0040] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application have been described in detail, for the skilled in the art, it still can be modified, or for the equivalent replacement of part of the technical features of the technical solutions recorded in the foregoing embodiments.
