DETAILED DESCRIPTION

[0023] The utility model is further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the utility model and are not used to limit the scope of the utility model. In addition, it should be understood that after reading the content taught by the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms also fall within the scope defined by this application.

[0024] like Figure 1-Figure 3 The figure shows a schematic diagram of the relevant structure of a conveyor belt type stone mill feeding system provided in this embodiment.

[0025] The feeding system of this embodiment is mainly used for feeding the stone mill, and the figure shows the related structure of 6 mills and 1 machine. It includes a feeding rack 1, a conveyor belt 4, 6 stone mills 2 and a stone mill feeding hopper 3 corresponding to each stone mill 2. The feeding rack 1 conveys materials from the upper part of one end of the conveyor belt 4 downward to the receiving hopper 9, and the materials fall into the conveyor belt 4 through the receiving hopper 9. Inner baffles 6 and outer baffles 5 are arranged on both sides of the conveyor belt 4 along the length direction. The inner baffles 6, the outer baffles 5 and the conveyor belt 4 form a material conveying channel, and the materials are conveyed in the inner baffles 6 and the outer baffles 5. A plurality of openings 8 are arranged on the inner baffle 6 in sequence along the material conveying direction. When the corresponding opening 8 is opened, the material flows downward into the stone mill feeding hopper 3 through the opening 8, and then flows downward into the stone mill 2 through the stone mill feeding hopper 3.

[0026] In this embodiment, a swingable movable closing plate 7 is correspondingly arranged at each opening 8, and the movable closing plate 7 is arranged between the inner baffle plate 6 and the outer baffle plate 5. As shown in the reference figure, one end of the movable closing plate 7 is hingedly connected to the inner baffle plate 6 and the hinge point is located behind the corresponding opening 8. The length of the movable closing plate 7 is greater than the width of the conveyor belt 4 and the bottom of the movable closing plate 7 is in contact with the conveyor belt 4. The swing of the movable closing plate 7 is driven by the cylinder 12, and one end of the cylinder 12 is hingedly connected to the outer baffle plate 5, and the output rod at the other end of the cylinder 12 is hingedly connected to the movable closing plate 7.

[0027] In the above structure of the present embodiment, when it is necessary to load all 6 millstones 2, first retract the cylinder 12 corresponding to the first opening 8. At this time, the cylinder 12 drives the movable closing plate 7 to swing outward to open the first opening 8. At the same time, since the length of the movable closing plate 7 is greater than the width of the conveyor belt 4, the non-hinged end of the movable closing plate 7 swings outward to the contact position with the outer baffle plate 5, that is, the position shown in the figure. Then, at this time, the material cannot be transported backward through the movable closing plate 7 due to the obstruction of the movable closing plate 7. The material can only enter the millstone feed hopper 3 downward through the first opening 8 to realize the loading of the first millstone 2. After the loading of the first millstone 2 is completed, the cylinder 12 corresponding to the first opening 8 extends out, driving the first movable closing plate 7 to swing inward to close the first opening 8. At this time, the material can flow to the second opening 8. Similarly, the second cylinder 12 is controlled to retract to open the second opening 8, so that the second millstone 2 can be loaded. The above actions can be performed one by one to complete the loading of all millstones 2. When it is necessary to load material to one of the stone mills 2 separately, the opening 8 in front of the corresponding opening 8 is closed and the opening 8 is opened. The operation is simple and easy to control.

[0028] As a preferred solution of this embodiment, in order to ensure the flexible movement of the movable sealing plate 7, a corresponding guide structure is also provided. Specifically, a guide plate 11 is fixed on the upper part of the inner baffle plate 6 and the outer baffle plate 5, and an arc-shaped guide groove 13 is provided on the guide plate 11. A guide column is provided on the upper part of the movable sealing plate 7 and can move along the guide groove 13 to realize the guidance of the movable sealing plate 7 during the swinging movement.

[0029] In the present embodiment, the movable sealing plate 7 is used to close the corresponding opening 8. When the movable sealing plate 7 swings inward, it will bring part of the material on the conveyor belt 4. The material is squeezed between the movable sealing plate 7 and the inner baffle plate 6, which may easily cause the opening 8 to be unable to be completely closed. Therefore, in the present embodiment, an inclined limiting plate 10 is arranged in front of each corresponding opening 8. Through the setting of the limiting plate 10, the movable sealing plate 7 does not need to be swung to a position in contact with the inner baffle plate 6. It only needs to be swung to a position in contact with the limiting plate 10 to prevent the material from entering the opening 8. The structure is simple and the use effect is good.

[0030] In this embodiment, an inner swing position sensor 15 is provided on the inner baffle plate 6, and the inner swing position sensor 15 can detect whether the movable sealing plate 7 is swung inwardly to a certain position, thereby providing feedback on the closing of the opening 8. An outer swing position sensor 14 is provided on the outer baffle plate 5, and the outer swing position sensor 14 can detect whether the movable sealing plate 7 is swung outwardly to a certain position, thereby providing feedback on the opening of the opening 8. An upper loading position sensor 16 and a lower loading position sensor 17 are provided on the millstone feed hopper 3, which are used to detect the height of the material in the millstone feed hopper 3, thereby providing feedback on whether the material needs to be added.
