Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, and in particular to a grain feeding and iron removal device. Background Technology

[0002] Before grain processing, impurities, especially iron impurities, need to be removed to prevent damage to machinery during subsequent processing. Patent 202320978687.0 discloses an iron removal device for a feeding belt, which uses a high-strength electromagnet installed on the feeding belt to attract iron impurities during transport. However, this technical solution requires manual removal of the impurities from the magnet and from the belt after they are attracted by the magnet. Since grain often contains a lot of impurities, frequent collection by personnel is necessary, resulting in high labor intensity and low automation, requiring further improvement. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a grain feeding and iron removal device to solve the problem of iron impurities not being automatically collected.

[0004] The purpose of this utility model is achieved through the following technical solution: a grain feeding and iron removal device, including a frame, with support legs provided on both the left and right sides of the frame, a slide rail, a slide plate, a first drive mechanism, and a collection bin provided on the frame, the slide rail being perpendicular to the left and right sides of the frame, the slide rail having a sliding groove, the bottom surface of the slide plate having a slider matching the sliding groove, the slider being fixedly connected to the slide plate, the first drive mechanism pushing the slide plate to move left and right along the slide rail, the collection bin and the first drive mechanism being located on opposite sides of the frame, the slide rail extending from above the frame to above the collection bin, and an electromagnet being provided on the bottom surface of the slide plate.

[0005] Furthermore, a second drive mechanism is provided on the skateboard, which drives the electromagnet to move up and down.

[0006] Furthermore, the first drive mechanism and the second drive mechanism have the same structure, and both are electric push rod structures.

[0007] Furthermore, a pressure plate is provided on the frame, the lower surface of the pressure plate is in close contact with the upper top surface of the slide plate, the two ends of the pressure plate are respectively fixedly connected to the frame, and the pressure plate is arranged parallel to the slide rail.

[0008] Furthermore, a plastic compartment is provided on the skateboard. The plastic compartment is a hollow cuboid structure. The electromagnet is located inside the plastic compartment, and the second drive mechanism pushes the plastic compartment to move up and down.

[0009] Furthermore, the slide plate is also provided with a spreading plate, which has an M-shaped structure. The spreading plate is located in front of the electromagnet, and the spreading plate and the electromagnet are on the same horizontal plane.

[0010] This utility model has the following advantages:

[0011] 1. The first drive mechanism pushes the slide plate and drives the electromagnet to move from the frame along the slide rail to the top of the collection bin, completing the electromagnet's adsorption and transfer of impurities. The automated operation eliminates the need for manual material handling and impurity collection, thus improving the efficiency of impurity processing.

[0012] 2. The second drive mechanism drives the electromagnet and the spreading plate to move up and down synchronously. This not only allows for precise adjustment of the adsorption height according to different equipment, but also enables the material to be spread evenly. Both mechanisms work together to improve the impurity removal effect. Attached Figure Description

[0019] like Figure 1 As shown, a grain feeding and iron removal device includes a frame 1, which is a frame structure with only left, right, front, and rear sides. Support legs 13 are installed on both sides of the frame 1, and these legs are used to fix the device above the conveyor belt. Two slide rails 2, a sliding plate 4, a first drive mechanism, a collection bin 11, and a second drive mechanism are installed on the top of the frame 1. The first and second drive mechanisms have the same structure and are both electric push rod structures. The first drive mechanism is the first electric push rod 6 shown in the figure, and the second drive mechanism is the second electric push rod 10. The slide rails 2 are perpendicular to the left and right sides of the frame 1 and are welded to the frame 1. A groove 3 is formed on the upper surface of each slide rail 2, and the bottom surface of the sliding plate 4 is provided with a groove corresponding to the groove 3. A matching elongated slider 5 is integrally connected to the lower surface of the slide plate 4. A first electric push rod 6 is horizontally fixedly connected to the right side of the frame 1. The output end of the first electric push rod 6 is fixedly connected to the upper surface of the slide plate 4. The first electric push rod 6 pushes the slide plate 4 to move left and right along the slide rail 2. A collection chamber 11 is installed on the left side of the frame 1. The collection chamber 11 is set opposite to the first electric push rod 6. The slide rail 2 extends from the top of the frame 1 to the top of the collection chamber 11. The left side of the frame 1 is connected to the top of the collection chamber 11. Two pressure plates 12 are installed on the frame 1. The lower surface of the pressure plate 12 is in close contact with the top surface of the slide plate 4 to prevent the slide plate 4 from detaching from the slide groove 3 due to vibration. The two ends of the pressure plate 12 are fixedly connected to the frame 1 respectively. The pressure plate 12 is set parallel to the slide rail 2.

[0020] The second electric push rod 10 is vertically mounted on the slide plate 4, and its output end passes through the slide plate 4 and is slidably connected to it. The output end of the second electric push rod 10 is fixedly connected to the plastic compartment 9. The plastic compartment 9 is a rectangular hollow structure. An electromagnet is installed inside the plastic compartment 9. The electromagnet includes an iron core 7 and a coil 8 wound on the iron core 7. The bottom surface of the iron core 7 is vertically fixed to the inner bottom surface of the plastic compartment 9. The output end of the second electric push rod 10 is also equipped with a spreading plate 14 and a connecting rod 15. The spreading plate 14 is an M-shaped plate structure. The sharp part of the middle section of the spreading plate 14 faces the opposite direction of the material conveying direction. The spreading plate 14 is located in front of the electromagnet. The spreading plate 14 and the electromagnet are on the same horizontal plane. The connecting rod 15 is a Y-shaped rod structure. Its two ends are fixedly connected to the spreading plate 14, and its other end is fixedly connected to the output end of the second electric push rod 10.

[0021] The working principle of this utility model is as follows: First, the support legs 13 are installed on the left and right sides of the feeding conveyor belt. Then, the second electric push rod 10 is activated, causing the spreading plate 14 and the electromagnet to move downwards together to above the conveyor belt. During the feeding process, the grain accumulated on the conveyor belt is thicker in the middle than at both ends. The spreading plate 14 evenly spreads the thicker grain, facilitating the subsequent adsorption of iron impurities by the electromagnet. After running for a period of time, feeding is stopped, and the second electric push rod 10 retracts upwards, causing the spreading plate 14 and the electromagnet to move upwards together. Then, the first electric push rod 6 is activated, which moves the sliding plate 4 along with the second electric push rod 10 and the spreading plate 14. The electromagnet and plastic compartment 9 are pushed above the collection chamber 11. Finally, the power to the electromagnet is turned off, and the iron impurities fall into the collection chamber 11. The entire process does not require manual cleaning of the iron impurities, thus improving processing efficiency. The second electric push rod 10 can adjust the height of the electromagnet arbitrarily, making it easy to make precise height adjustments for different materials. The spreading plate 14 is installed on the second electric push rod 10 along with the electromagnet, which can spread the material evenly and improve the electromagnet's adsorption effect on impurities. The plastic compartment 9 is made of polyethylene, which can isolate the coil 8 from the iron core 7, preventing the iron impurities from directly contacting and impacting the electromagnet during the adsorption process.

[0022] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
