Description

Technical Field

[0001] This utility model relates to the field of conveying device technology, and specifically discloses a raw material conveying device for fused silica production. Background Technology

[0002] Fused silica is an amorphous form of silicon dioxide. It is a typical glass with a long-range disordered atomic structure. It provides high operating temperature and low coefficient of thermal expansion through three-dimensional cross-linking. It represents a significant breakthrough in terms of usage and price compared to zircon materials, making it a more ideal material for engineering applications. The production of fused silica requires the use of raw material conveying devices to deliver the raw materials into the melting device for melting and production.

[0003] Chinese patent CN210027542U discloses a raw material conveying device for fused silica production. The bottom of the conveying device has a connecting structure, and a movable roller is connected to the side of the connecting structure away from the conveying device. The beneficial effects achieved by this utility model are: movable rollers are fixedly connected to the four corners of the bottom of the connecting structure, and the movable rollers are silent universal wheels. By pushing with a push plate, the conveying device can be moved more conveniently. The output end of the telescopic cylinder is movably connected to the connecting plate through the slot using a pin. The extension of the telescopic cylinder can lift the conveying device. Because the bottom of the front end of the conveying device is movably connected together, the lifting of the conveying device can make the rear end of the conveying device continuously rise to the tilting structure, so that the quartz sand in the conveying device can be automatically poured out, improving work efficiency. By controlling the handle, the insert plate can be inserted into the fixed groove so as to firmly connect the sealing structure to the front end of the conveying device and prevent the quartz sand from leaking out during the transportation process.

[0004] The aforementioned document discloses a raw material conveying device for fused silica production, whose sealing structure requires manual opening or closing by operators, making the operation rather cumbersome. Therefore, a raw material conveying device for fused silica production is needed to solve this problem. Utility Model Content

[0005] This utility model proposes a raw material conveying device for fused silica production. The device automatically opens and closes the box door through a lifting mechanism, which is labor-saving and efficient.

Two support plates are fixedly connected to the left side of the upper surface of the base. First connecting shafts are fixedly connected to the lower sides of both the front and rear end faces of the housing. The two first connecting shafts are rotatably connected to the two support plates respectively. A lifting mechanism is provided between the base and the housing. A door is rotatably connected to the left end of the housing. A linkage mechanism is provided between the housing and the door.

Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0022] Please see Figure 1-4 A raw material conveying device for fused silica production includes a base 1 and a housing 2. Two support plates 4 are fixedly connected to the left side of the upper surface of the base 1. First connecting shafts 3 are fixedly connected to the lower sides of both the front and rear end faces of the housing 2. The two first connecting shafts 3 are rotatably connected to the two support plates 4 respectively. A lifting mechanism is provided between the base 1 and the housing 2. A door 5 is rotatably connected to the left end of the housing 2. A linkage mechanism is provided between the housing 2 and the door 5. The linkage mechanism includes: The fixing rod 6 is fixedly connected to the left end face of the box door 5, and the front and rear sides of the fixing rod 6 are fixedly connected to the second connecting shaft 7. There are two first connecting rods 8, which are rotatably connected to the front and rear end faces of the housing 2 via rotating shafts. The upper ends of the two first connecting rods 8 are rotatably connected to the second connecting rods 9, and the other ends of the two second connecting rods 9 are rotatably connected to the two second connecting shafts 7 respectively. There are two third links 10, which are rotatably connected to the front and rear end faces of the base 1 via rotating shafts. The other ends of the two third links 10 are rotatably connected to the lower ends of the two first links 8 respectively.

[0023] In this embodiment: the lifting mechanism causes the box body 2 to rotate upward along the first connecting shaft 3, which in turn drives the third connecting rod 10 to rotate. The third connecting rod 10 further drives the first connecting rod 8 to rotate, which in turn drives the box door 5 to rotate upward through the second connecting rod 9, thereby opening the box door 5. The linkage mechanism drives the box door 5 to open while the box body 2 rotates upward, which facilitates unloading. Conversely, when the box body 2 rotates downward and falls, it drives the box door 5 to rotate downward and close. There is no need for the operator to manually open and close the box door 5, which is convenient to use.

[0024] As a technical optimization of this utility model, the lifting mechanism includes a lead screw 12 rotatably connected inside the base 1. A servo motor 13 with its output end fixedly connected to the lead screw 12 is installed on the outer wall of the base 1. A slider 14 is threadedly connected to the outer wall of the lead screw 12. Two support rods 15 are rotatably connected to the outer wall of the slider 14 through a rotating shaft. The other ends of the two support rods 15 are rotatably connected to the bottom end face of the housing 2.

[0025] In this embodiment: the servo motor 13 is started, the servo motor 13 drives the lead screw 12 to rotate, which in turn drives the slider 14 to move to the left or right. The slider 14 further drives the box 2 to rotate up or down along the first connecting shaft 3 through the support rod 15, thereby facilitating unloading or loading.

[0026] As a technical optimization of this utility model, a lid 11 is movably provided on the upper end surface of the box 2.

[0027] In this embodiment, a lid 11 is provided above the box body 2 to prevent the raw materials inside the box body 2 from spilling out.

[0028] As a technical optimization of this utility model, a storage battery 16 is provided on the lower end surface of the base 1, and the servo motor 13 is electrically connected to the storage battery 16.

[0029] In this embodiment, the battery 16 facilitates the supply of power to the servo motor 13.

[0030] As a technical optimization of this utility model, four symmetrically distributed wheels 17 are installed on the outer wall of the base 1.

[0031] In this embodiment, the device is moved by installing wheels 17 on the outer wall of the base 1.

[0032] As a technical optimization of this utility model, a push handle 18 is provided on the right end face of the base 1.

[0033] In this embodiment: a push handle 18 is provided on the right end face of the base 1 to facilitate the operator to push the equipment to move.

[0034] As a technical optimization of this utility model, a control switch is provided on the outer wall of the base 1, and the servo motor 13 and the battery 16 are both electrically connected to the control switch.

[0035] In this embodiment, the servo motor 13 can be easily controlled to work normally by means of a control switch.

[0036] The working principle and usage process of this utility model are as follows: During unloading, the box cover 11 is first removed, and then the servo motor 13 is started. The servo motor 13 drives the lead screw 12 to rotate, which in turn drives the slider 14 to move to the left. The slider 14 further drives the box body 2 to rotate upward along the first connecting shaft 3 through the support rod 15, which in turn drives the third connecting rod 10 to rotate. The third connecting rod 10 further drives the first connecting rod 8 to rotate, which in turn drives the box door 5 to rotate upward through the second connecting rod 9, thereby opening the box door 5. The box door 5 is opened at the same time as the box body 2 rotates upward through the linkage mechanism, which facilitates unloading. Conversely, when the box body 2 rotates downward and falls, it drives the box door 5 to rotate downward and close. There is no need for the operator to manually open and close the box door 5, which is convenient to use.
