Description
Technical Field
[0001] This utility model relates to the field of hopper technology, and in particular to an adjustable hopper. Background Art
[0002] Currently, hoppers are a common material storage and conveying device, widely used in various industries. They can be used for different production processes and material characteristics to meet different production needs. Especially in small integrated processing equipment with limited space, they can effectively control the flow rate and quantity of materials, extend the service life of the equipment, improve production efficiency, and ensure production safety.
[0003] Traditional hoppers mainly consist of an inlet, side walls, and an outlet. They are generally not used alone; the front end is connected to a material conveying device, and the rear end is connected to a device for preliminary material processing, such as crushing or incineration. However, this single-input, single-output hopper requires shutdown for maintenance and cleaning when the outlet becomes blocked, which greatly reduces production efficiency and increases costs. To address this issue, we provide an adjustable hopper. Utility Model Content
[0004] The purpose of this invention is to overcome the defects in the existing technology and provide an adjustable hopper.
[0005] To achieve the above objectives, the technical solution of this utility model is to design an adjustable hopper, including a double-cavity hopper. The lower end of the double-cavity hopper is provided with two discharge ports. The lower end of the double-cavity hopper is connected to two square straight pipes. The outer side of each square straight pipe is equipped with a connecting flange. The inner cavity of the double-cavity hopper is symmetrically connected with partitions. The inner cavity of the double-cavity hopper is provided with a material guiding adjustment mechanism, which is located between the two partitions.
[0006] The material guiding and adjusting mechanism includes a servo motor installed on the outside of the double-chamber hopper. The output end of the servo motor passes through the double-chamber hopper via a drive shaft and extends to its outside. A fixing block is installed on the outside of the drive shaft. A sealing plate is connected to the upper end of the fixing block. An arc-shaped plate is connected to the upper end of the sealing plate. Both sides of the sealing plate are in contact with the partition. Material guiding grooves are provided on the outside of the partition. A material blocking assembly is provided on the outside of the drive shaft.
[0007] A further preferred technical solution is that both sides of the inner cavity of the dual-cavity hopper are connected to inclined guide plates, and the inclined guide plates are located between the partitions.
[0008] In a further preferred technical solution, the material blocking assembly includes an arc-shaped gear mounted on the outside of the drive shaft. A first support shaft is symmetrically connected to the outside of the dual-chamber hopper. A first gear corresponding to the position of the arc-shaped gear is rotatably connected to the outside of each of the first support shafts. A second gear meshes with the outside of each of the first gears. A second support shaft is rotatably connected to the inner cavity of each of the second gears. One end of the second support shaft is mounted on the outside of the dual-chamber hopper. A toothed plate meshes with the outside of each of the second gears. One end of the toothed plate is connected to a connecting rod. A first square groove is symmetrically arranged on the outside of the dual-chamber hopper. A groove is provided on the corresponding side of each partition. A second square groove communicating with the groove is provided on the outside of each partition. One end of each connecting rod passes through the first square groove and the second square groove and extends into the inner cavity of the groove. One end of the connecting rod is connected to a support bar located in the inner cavity of the groove. A slanted baffle is connected to one side of the support bar.
[0009] A further preferred technical solution is that a protective shell is installed on the outer side of the dual-chamber hopper, and a screw-on cover plate is connected to the outer side of the protective shell. The protective shell is located on the outer side of the arc-shaped gear, the first gear, and the second gear.
[0010] A further preferred technical solution is that the outer side of the dual-chamber hopper is connected to a fixed plate, the upper end of the fixed plate is provided with a limit groove, and the upper end of the toothed plate is connected to a T-shaped block that slides with it.
[0011] A further preferred technical solution is that the inner cavity of the groove is provided with a sliding groove, and a slider is connected to one side of the support bar for sliding contact.
[0012] A further preferred technical solution is that a ratchet is installed on the outside of the drive shaft, the outside of the ratchet engages with a pawl, a rotary cylinder is installed on the outside of the double-chamber hopper, and the output end of the rotary cylinder is connected to the pawl.
[0013] In a further preferred technical solution, both sides of the sealing plate are semi-circular, and a fixing shell is installed on the outer side of the dual-chamber hopper, with the fixing shell located outside the servo motor.
[0014] In a further preferred technical solution, two top plates are screwed to the upper end of the dual-chamber hopper, and supplementary lights and cameras are installed at the lower end of each top plate.
[0015] The advantages and beneficial effects of this utility model are as follows: 1. The material is received by the arc-shaped plate at the upper end of the sealing plate of the material guiding adjustment mechanism, and the material is discharged by the vibration of its built-in vibrator. Then, the material is discharged through the material guiding groove on the outside of the two partitions, so that the material enters the two chambers of the double chamber hopper and is discharged through the discharge port. It is convenient to discharge material through two discharge ports at the same time. Compared with the same amount of material being discharged from a single discharge port, the probability of blockage is reduced, and the use effect is effectively improved. When one chamber of the double chamber hopper is blocked, the discharge direction can be adjusted by the material guiding adjustment mechanism. When one chamber is blocked, the material continues to be discharged from the other chamber. The blocked chamber can be cleaned and repaired in time, thus avoiding the need to stop work for maintenance after blockage, as is the case with traditional single-outlet hoppers. This effectively improves the working efficiency of this hopper and makes it easy to use.
[0016] 2. When the drive shaft drives the ratchet to rotate, the output end of the rotary cylinder drives the pawl to rotate away from the ratchet. When the drive shaft stops rotating, the output end of the rotary cylinder drives the pawl to rotate in the opposite direction and engage with the outside of the ratchet. This facilitates effective engagement and fixation of the ratchet, thereby effectively limiting the drive shaft. This ensures that the sealing plate can be stably supported whether it is in a horizontal or inclined state, preventing materials from falling onto the sealing plate and the upper part of the arc plate and impacting the sealing plate, thus avoiding impact on its stability and effectively improving the performance.

DETAILED DESCRIPTION
[0031] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.
[0032] Reference Figure 1-13 An adjustable hopper includes a double-cavity hopper 1, with two discharge ports 2 at the lower end of the double-cavity hopper 1. The lower end of the double-cavity hopper 1 is connected to two square straight pipes 3, and connecting flanges 4 are installed on the outer side of each square straight pipe 3. The inner cavity of the double-cavity hopper 1 is symmetrically connected to partitions 5, and the inner cavity of the double-cavity hopper 1 is provided with a material guiding adjustment mechanism 7, which is located between the two partitions 5.
[0033] The material guiding adjustment mechanism 7 includes a servo motor 71 installed on the outside of the double-cavity hopper 1. The output end of the servo motor 71 passes through the double-cavity hopper 1 through the drive shaft 72 and extends to its outside. A fixing block 73 is installed on the outside of the drive shaft 72. A sealing plate 74 is connected to the upper end of the fixing block 73. An arc plate 75 is connected to the upper end of the sealing plate 74. Both sides of the sealing plate 74 are in contact with the partition plate 5. Material guiding grooves 13 are provided on the outside of the partition plate 5. Both sides of the sealing plate 74 are semi-circular. Inclined guide plates 6 are connected to both sides of the inner cavity of the double-cavity hopper 1. The inclined guide plates 6 are located between the partition plates 5. A fixing shell 12 is installed on the outside of the double-cavity hopper 1. The fixing shell 12 is located on the outside of the servo motor 71.
[0034] When material is introduced from above the double-chamber hopper 1, it enters between the two partitions 5 and then falls onto the upper end of the arc-shaped plate 75 and the sealing plate 74. Two inclined guide plates 6 are designed to effectively guide the material. An external vibrator is installed inside the arc-shaped plate 75 to facilitate vibration and discharge of the material. The material then flows from the guide trough 13 outside the partition 5 into the two chambers of the double-chamber hopper 1. The bottom of the guide trough 13 is inclined for easy discharge. Finally, the material is discharged through the outlet 2 and then through the square straight pipe 3. When the left chamber of the double-chamber hopper 1 becomes blocked and cannot discharge, the output of the servo motor 71 drives the drive shaft 72 to rotate to the left. The drive shaft 72, through the fixing block 73, drives the sealing plate 74 to rotate. Both sides of the sealing plate 74 are semi-circular, allowing it to fit against the partition 5 and rotate, facilitating use. Subsequently, the right side of the sealing plate 74 tilts downwards, and its left side tilts upwards, gradually separating from the partition 5. At this time, the drive shaft 72 rotates, driving the material blocking assembly to operate. Then, one of the inclined baffles 719 in the material blocking assembly moves to the upper left of the sealing plate 74 to block it, preventing material from entering the left cavity of the double-cavity hopper 1 from this point (the gap between the left side of the sealing plate 74 and the partition 5). Then, the material enters the right cavity of the double-cavity hopper 1 from the gap between the right side of the sealing plate 74 and the partition 5, and can continue to discharge, avoiding the hopper from becoming blocked and unable to continue working, requiring a break before it can work again. While the material continues to be discharged through the right cavity of the double-cavity hopper 1, maintenance and cleaning operations such as maintenance of the left cavity of the double-cavity hopper 1 can be performed, effectively improving the usage effect. When the right cavity of the double-cavity hopper 1 becomes blocked, the operation is reversed in the same way as above, and the material can continue to be discharged through the left cavity of the double-cavity hopper 1, which is convenient for use.
[0035] A material stop assembly is provided on the outer side of the drive shaft 72. The material stop assembly includes an arc-shaped gear 78 mounted on the outer side of the drive shaft 72. A first support shaft 710 is symmetrically connected to the outer side of the double-cavity hopper 1. A first gear 79 corresponding to the position of the arc-shaped gear 78 is rotatably connected to the outer side of the first support shaft 710. A second gear 711 meshes with the outer side of each of the first gears 79. A second support shaft 712 is rotatably connected to the inner cavity of each of the second gears 711. One end of the second support shaft 712 is mounted on the outer side of the double-cavity hopper 1. A toothed plate 713 meshes with the outer side of each of the second gears 711. A connecting rod 717 is connected to one end of the toothed plate 713. A first square groove 8 is symmetrically provided on the outer side of the double-cavity hopper 1. A partition plate 5 is... Each side of the corresponding plate is provided with a groove 14. The outer side of the partition plate 5 is provided with a second square groove 15 that communicates with the groove 14. One end of the connecting rod 717 passes through the first square groove 8 and the second square groove 15 and extends into the inner cavity of the groove 14. One end of the connecting rod 717 is connected to the support bar 718, which is located in the inner cavity of the groove 14. One side of the support bar 718 is connected to the inclined baffle 719. The outer side of the double cavity hopper 1 is connected to the fixing plate 714. The upper end of the fixing plate 714 is provided with a limit groove 715. The upper end of the toothed plate 713 is connected to a T-shaped block 716 that slides with it. The inner cavity of the groove 14 is provided with a sliding groove 16. One side of the support bar 718 is connected to a slider 720 that slides with it.
[0036] When the servo motor 71 drives the drive shaft 72 to rotate to the right (from the perspective of the servo motor 71), the drive shaft 72 drives the sealing plate 74 to rotate to the right through the fixing block 73. The left side of the sealing plate 74 tilts upward and its right side tilts downward. At the same time, the drive shaft 72 synchronously drives the arc gear 78 to rotate to the right, which then engages with the first gear 79 on its outer side, causing the first gear 79 to rotate. The first gear 79 synchronously drives the second gear 711, which engages with it, to rotate. The second gear 711 drives the toothed plate 713 to move to the right, and the toothed plate 713 is positioned in the limiting groove 715 at the upper end of the fixing plate 714 by the T-shaped block 716. The toothed plate 713, through the connecting rod 717, passes through the first square groove 8 and the second square groove 15, driving the support bar 718 and its side inclined baffle 719 to move to the right. The inclined baffle 719 then moves to the upper left side of the sealing plate 74, at which point it is in a blocked state in the left cavity of the double-cavity hopper 1. This effectively prevents material from entering the left cavity of the double-cavity hopper 1 from the gap between the left side of the sealing plate 74 and the partition 5, thus preventing more serious blockage and slower material discharge, which would affect the efficiency of subsequent material processing. Therefore, this baffle assembly effectively improves the discharge effect of the hopper and is convenient to use.
[0037] A protective shell 76 is installed on the outside of the double-chamber hopper 1. A screw-on cover plate 77 is connected to the outside of the protective shell 76. The protective shell 76 is located on the outside of the arc gear 78, the first gear 79 and the second gear 711, which can protect the mechanical parts such as the arc gear 78, the first gear 79 and the second gear 711 from being exposed and affecting their service life.
[0038] A ratchet 721 is mounted on the outside of the drive shaft 72, and a pawl 722 is engaged on the outside of the ratchet 721. A rotary cylinder 723 is mounted on the outside of the double-chamber hopper 1, and the output end of the rotary cylinder 723 is connected to the pawl 722.
[0039] When the drive shaft 72 drives the ratchet 721 to rotate, the output end of the rotary cylinder 723 drives the pawl 722 to rotate away from the ratchet 721. When the drive shaft 72 stops rotating, the output end of the rotary cylinder 723 drives the pawl 722 to rotate in the opposite direction and engage with the outside of the ratchet 721. This facilitates effective engagement and fixation of the ratchet 721, thereby effectively limiting the drive shaft 72. This ensures that the sealing plate 74 can be stably supported whether it is in a horizontal or inclined state, preventing materials from falling onto the upper part of the sealing plate 74 and the arc plate 75 and impacting the sealing plate 74, thus avoiding impact on its stability and effectively improving the performance.
[0040] Two top plates 9 are screwed to the upper end of the double-chamber hopper 1. A supplementary light 10 and a camera 11 are installed at the lower end of each top plate 9. The camera 11 effectively monitors the two chambers of the double-chamber hopper 1, and the supplementary light 10 provides illumination, making the monitored image clearer. This allows the staff to see more carefully whether there is any blockage inside the two chambers of the double-chamber hopper 1, and to adjust the material guiding direction through the material guiding adjustment mechanism 7 in a timely manner. It also allows for timely cleaning and maintenance of the blocked chambers, thus avoiding the need for shutdown and maintenance required after blockage, as is the case with traditional single-outlet hoppers. This effectively improves the working efficiency of the hopper and makes it easier to use.
[0041] Working Principle: This invention connects to an external controller, servo motor 71, external vibrator, rotary cylinder 723, supplementary light 10, and camera 11. During use, when material is introduced from above the double-chamber hopper 1, it enters between the two partitions 5 and falls onto the upper ends of the arc-shaped plate 75 and sealing plate 74. Two inclined guide plates 6 are designed to effectively guide the material. An external vibrator is installed inside the arc-shaped plate 75 for vibrating and discharging the material. The material then flows from the guide trough 13 outside the partitions 5 into the two chambers of the double-chamber hopper 1. The bottom of the guide trough 13 is inclined for easy discharge. Finally, the material is discharged through the outlet 2 and then through a square straight pipe. 3. Discharge: The dual-chamber hopper 1 features a camera 11 for effective monitoring of both chambers, illuminated by a supplementary light 10. This enhances the clarity of the camera's view, allowing operators to easily inspect the chambers for blockages. The guide mechanism 7 adjusts the material direction, and the blocked chamber is promptly cleaned and repaired. This avoids the need for downtime repairs required by traditional single-outlet hoppers, thus significantly improving efficiency and ease of use. If the right chamber of the dual-chamber hopper 1 is found to be blocked (from the servo motor 71's perspective), preventing material discharge, the camera 11 provides additional lighting to the chambers. The controller activates the output of the servo motor 71, causing the drive shaft 72 to rotate to the left. The drive shaft 72, via the fixing block 73, rotates the sealing plate 74. Both sides of the sealing plate 74 are semi-circular, allowing it to fit against the partition 5 and rotate easily. Subsequently, the left side of the sealing plate 74 tilts downwards, and its right side tilts upwards, gradually separating from the partition 5. At this time, the rotation of the drive shaft 72 simultaneously drives the material-blocking assembly. A baffle 719 within the material-blocking assembly moves to the upper right of the sealing plate 74, blocking material from entering the right cavity of the double-cavity hopper 1 from this gap (between the right side of the sealing plate 74 and the partition 5). The material then enters from the gap between the right side of the sealing plate 74 and the partition 5. Material enters the left cavity of the double-cavity hopper 1 through the gap, allowing for continued material discharge and preventing hopper blockage that would prevent further operation and necessitate a break. Simultaneously, the right cavity of the double-cavity hopper 1 can be cleaned and maintained through the left cavity, effectively improving efficiency. Similarly, if the left cavity becomes blocked, the operation is reversed to allow continued discharge through the right cavity, facilitating use. When the drive shaft 72 rotates the ratchet 721, the output of the rotary cylinder 723 causes the pawl 722 to rotate and disengage from the ratchet 721. When the drive shaft 72 stops rotating, the output of the rotary cylinder 723 causes the pawl 722 to rotate in the opposite direction and engage with the outside of the ratchet 721.This design facilitates effective engagement and fixation of the ratchet 721, thereby effectively limiting the drive shaft 72. This ensures stable support for the sealing plate 74 regardless of whether it is horizontal or inclined, preventing material from falling onto the sealing plate 74 and the upper part of the curved plate 75 and impacting the sealing plate 74, thus avoiding any impact that could affect its stability and effectively improving its performance.
[0042] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
