Description

Technical Field

[0001] This utility model relates to a feeding device, specifically a quartz sand feeding device, belonging to the field of quartz sand production and processing technology. Background Technology

[0002] Quartz sand feeding devices are specialized unloading and feeding equipment designed for quartz sand. They are mainly used to control the feeding speed, flow rate, and uniformity of quartz sand to avoid blockage or uneven feeding. In a quartz sand conveying system, the hopper serves as a temporary storage container for the material, storing the quartz sand. The bottom of the hopper is connected to the feeding device, which releases the material quantitatively and evenly. The material output from the feeding device falls directly onto the conveyor belt, which then transports it to subsequent processes such as processing, storage, or sorting. This type of device is commonly used in industries such as glass manufacturing, ceramic production, casting, and water treatment (quartz sand filter media).

[0003] However, traditional quartz sand feeding devices use a screw thread to drive the sliding adjustment plate to control the discharge port opening. The screw has to handle both wide-range adjustment and fine control, and the adjustment speed is relatively slow, resulting in low adjustment efficiency. Especially when the discharge port opening is changed significantly, the screw needs to be rotated repeatedly, which is time-consuming and labor-intensive. At the same time, the feel is relatively vague when fine-tuning the large-stroke screw, making it difficult to accurately control the discharge port opening by turning the handwheel a few times. Therefore, inexperienced operators are prone to inaccurate control of the adjustment amount, which can lead to fluctuations in the discharge flow rate, increasing the difficulty of debugging and production errors. Utility Model Content

[0004] The purpose of this invention is to provide a quartz sand feeding device to solve the above-mentioned problems. The device provides coarse adjustment positions for the sliding of the adjustment plate through the cooperation of the locking block and the locking groove. Each position corresponds to the basic opening of the material outlet, so that the adjustment plate can be quickly moved to the corresponding position of the target opening range. Then, the sliding plate is driven by the lead screw to achieve fine adjustment within a single position, forming a graded control mode of "coarse adjustment to determine the range, fine adjustment to determine the precise value", which makes the adjustment of the outlet opening more convenient and accurate.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a quartz sand feeding device includes a mounting frame, on which a hopper is mounted. Two sliding rods are fixedly connected to the discharge port at the bottom of the hopper. An adjusting plate is slidably connected to the sliding rods. A coarse adjusting structure and a fine adjusting structure are mounted on the adjusting plate. The coarse adjusting structure includes two locking blocks, which are slidably connected to the adjusting plate. Multiple locking slots are equidistantly provided on both sliding rods, and the locking blocks engage with the locking slots. The fine adjusting structure includes a lead screw, which is rotatably connected to the adjusting plate. A sliding plate is threaded onto the lead screw, and the sliding plate is slidably connected to the adjusting plate and the hopper.

[0006] Preferably, the two slide bars are symmetrically distributed, and the cross-sections at both ends of the adjusting plate are U-shaped.

[0007] Preferably, the end of the card block that engages with the card slot has a trapezoidal structure, and a connecting rod is fixedly connected between the two card blocks.

[0008] Preferably, a tension spring is installed between the connecting rod and the adjusting plate, with the top end of the tension spring fixedly connected to the adjusting plate and the bottom end of the tension spring fixedly connected to the connecting rod.

[0009] Preferably, the bottom end of the adjusting plate is fixedly connected to a plurality of guide rods, and the connecting rod is slidably connected to the guide rods.

[0010] Preferably, the connecting rod has a "U" shaped structure, and the guide rod has a "T" shaped cross-section.

[0011] Preferably, two sliding grooves are formed on the inner wall of the adjusting plate, and rollers are rotatably connected to both sliding rods, with the rollers rollingly connected to the sliding grooves.

[0012] Preferably, the two grooves are symmetrically distributed, and a handwheel is fixedly connected to the end of the lead screw.

[0013] The beneficial effects of this utility model are as follows: Two sliding rods are fixedly connected to the discharge port at the bottom of the hopper. An adjusting plate is slidably connected to the sliding rods, and two locking blocks are slidably connected to the adjusting plate. Multiple locking slots are equally spaced on both sliding rods, and the locking blocks engage with the locking slots. A lead screw is rotatably connected to the adjusting plate, and a sliding plate is threaded onto the lead screw. The sliding plate is slidably connected to the adjusting plate and the hopper. The cooperation between the locking blocks and the locking slots provides coarse adjustment positions for the sliding of the adjusting plate. Each position corresponds to the basic opening of the discharge port, thereby enabling the adjusting plate to be quickly moved to the corresponding position within the target opening range. Then, the lead screw drives the sliding plate to achieve fine adjustment within a single position, forming a graded control mode of "coarse adjustment to define the range, fine adjustment to define the precise value," which makes the adjustment of the discharge port opening more convenient and precise.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-6 As shown, a quartz sand feeding device includes a mounting frame 1, on which a hopper 2 is mounted. Two sliding rods 3 are fixedly connected to the discharge port at the bottom of the hopper 2. An adjusting plate 4 is slidably connected to the sliding rods 3. A coarse adjusting structure 5 and a fine adjusting structure 6 are mounted on the adjusting plate 4. The coarse adjusting structure 5 includes two locking blocks 501, which are slidably connected to the adjusting plate 4. Multiple slots 502 are equally spaced on both sliding rods 3, and the locking blocks 501 engage with the slots 502. The fine adjusting structure 6 includes a lead screw 601, which is rotatably connected to the adjusting plate 4. A sliding plate 602 is threaded onto the lead screw 601, and the sliding plate 602 is slidably connected to the adjusting plate 4 and the hopper 2. The two sliding rods 3 are symmetrically distributed, and the cross-sections at both ends of the adjusting plate 4 are U-shaped.

[0023] As a technical optimization of this utility model, the end of the card block 501 that engages with the card slot 502 is trapezoidal in shape, which guides the card block 501 and facilitates quick engagement of the card block 501 with the card slot 502. A connecting rod 503 is fixedly connected between the two card blocks 501. The connecting rod 503 is U-shaped and can drive the two card blocks 501 to slide simultaneously, improving the convenience of operation.

[0024] As a technical optimization of this utility model, a tension spring 504 is installed between the connecting rod 503 and the adjusting plate 4. The top end of the tension spring 504 is fixedly connected to the adjusting plate 4, and the bottom end of the tension spring 504 is fixedly connected to the connecting rod 503. The tension spring 504 uses elastic tension to make the locking block 501 automatically engage with the slot 502, thereby locking the coarse adjustment position. A plurality of guide rods 505 are fixedly connected to the bottom end of the adjusting plate 4. The connecting rod 503 is slidably connected to the guide rods 505. The cross-section of the guide rod 505 is a "T" shaped structure. The guide rod 505 plays a sliding limiting role on the connecting rod 503, ensuring that the locking block 501 moves vertically, while preventing the connecting rod 503 and the locking block 501 from slipping off the adjusting plate 4.

[0025] As a technical optimization of this utility model, two sliding grooves 7 are provided on the inner wall of the adjusting plate 4, and rollers 8 are rotatably connected to the two sliding rods 3. The rollers 8 are rolledly connected to the sliding grooves 7, and the two sliding grooves 7 are symmetrically distributed. The setting of the rollers 8 can not only reduce the frictional resistance between the adjusting plate 4 and the sliding rods 3, but also prevent the adjusting plate 4 from sliding off the sliding rods 3 due to excessive sliding, thereby increasing the stability of the adjusting plate 4 when sliding.

[0026] As a technical optimization of this utility model, a handwheel 603 is fixedly connected to the end of the lead screw 601. By rotating the handwheel 603, the lead screw 601 is driven to rotate, so that the operator can easily drive the lead screw 601 to rotate.

[0027] In use, when it is necessary to adjust the opening of the discharge port of hopper 2, the connecting rod 503 is pulled down. The connecting rod 503 causes the locking block 501 to disengage from the current locking slot 502. At this time, the locking block 501 drives the tension spring 504 to extend. Then, the adjusting plate 4 slides horizontally along the slide rod 3, thereby changing the opening of the discharge port of hopper 2. The distance between the locking slots 502 is set to a fixed displacement corresponding to the opening position of the discharge port. When the adjusting plate 4 is adjusted to the appropriate position, the connecting rod 503 is released. At this time, the tension spring 504 resets and drives the connecting rod 503 and the locking block 501 to move upward, so that the locking block 501 engages in the corresponding locking slot 502, thereby quickly completing the limiting of the adjusting plate 4 and thus quickly completing the coarse adjustment of the discharge port opening. When the adjusting plate 4 slides on the slide rod 3, the roller 8 rolls in the slide groove 7. The roller 8 not only reduces the frictional resistance between the adjusting plate 4 and the slide rod 3, but also prevents the adjusting plate 4 from sliding off the slide rod 3 due to excessive sliding, thereby increasing the stability of the adjusting plate 4 when sliding. When it is necessary to further adjust the opening of the discharge port more precisely, turn the handwheel 603. The handwheel 603 drives the lead screw 601 to rotate. When the lead screw 601 rotates, the thread drives the slide plate 602 to move along the axial direction of the lead screw 601 and slide outward of the adjusting plate 4, thereby further blocking the discharge port. This makes it easier to make more precise adjustments to the opening of the discharge port within the current gear. Furthermore, the cooperation between the coarse adjustment structure 5 and the fine adjustment structure 6 makes the adjustment of the discharge port opening more time-saving and labor-saving.
