Description

Technical Field

[0001] The utility model relates to the technical field of discharging funnels, in particular to a discharging funnel. Background Art

[0002] The discharge funnel is a commonly used equipment in ports, docks, factories and other places. Its main function is to load and unload materials. The use of the funnel eliminates the labor intensity of manual handling to a great extent, thus saving time and improving work efficiency. Therefore, the discharge funnel is increasingly favored by dock workers. The discharge funnel is generally set between the double-layer conveyor belts. During the material conveying process of the upper belt conveyor, the material falls from the discharge funnel to the belt of the lower belt conveyor.

[0003] After searching, we found that in the published patent (CN215100016U, an open and close dust cover for a wharf funnel belt conveyor), the problem of the unloading funnel on the belt conveyor running back and forth and being unable to be covered was solved. The device does not require a power input system and a control system. It completely relies on the operation of the unloading funnel equipment to separate the rubber elastic plate, and then relies on the weight of the rubber elastic plate to automatically fall and cover. Although it has a good wind and dustproof effect, the discharge funnel lacks a corresponding buffer structure. During the falling process, the material will not only cause a certain impact force on the conveyor belt below, but the material is also easy to cause blockage in the funnel, which requires manual dredging, affecting the discharge efficiency. Therefore, we have introduced a new discharge funnel. Utility Model Content

[0004] The main purpose of the utility model is to provide a discharging funnel, which can effectively solve the problems in the background technology.

[0007] By adopting the above technical solution, the entire discharge funnel can be installed at the discharge port of the upper conveyor belt by bolts, so that the lower discharge port of the discharge funnel is located on the lower conveyor belt.

[0008] Preferably, the stirring mechanism includes a motor, a rotating rod is fixedly installed on the output end of the motor, a driving gear is fixedly connected to the right end of the rotating rod, a driven gear is meshingly connected to the front surface of the driving gear, a rotating column is fixedly connected to the right end of the driven gear, a rotating cylinder is inserted and fixedly connected to the outer surface of the rotating column, and a plurality of stirring rods are fixedly connected to the outer surface of the rotating cylinder.

[0009] By adopting the above technical solution, a plurality of stirring rods are driven by a motor to stir the material inside the lower hopper, so that the material can flow inside the hopper and fall smoothly.

[0010] Preferably, the motor is fixedly mounted on the left end of the connection box, and the rotating rod is interlacedly connected with the connection box.

[0011] By adopting the above technical solution, the motor is installed on the outside of the connection box, making the motor easy to maintain.

[0012] Preferably, the driving gear and the driven gear are both located inside the driving groove, and the outer surface of the driving gear and the outer surface of the driven gear are not in contact with the inner wall of the driving groove.

[0013] By adopting the above technical solution, the driving gear and the driven gear are both arranged in the driving groove, so as to prevent the driving gear and the driven gear from being adhered to dust and affecting the meshing effect.

[0014] Preferably, the left end of the driven gear is movably connected to the left groove wall of the driving groove through a bearing, and the end of the rotating column away from the driven gear is movably connected to the right wall of the lower silo.

[0016] Preferably, the plurality of stirring rods are all located inside the lower hopper, and the plurality of stirring rods are staggeredly distributed.

[0017] By adopting the above technical solution, the material in the discharge funnel is stirred by a plurality of stirring rods, so that the fluidity of the material inside the discharge funnel can be increased to avoid internal blockage thereof.

[0018] Preferably, the buffer mechanism includes a movable rod, a connecting tube is inserted and fixedly connected to the outer surface of the movable rod, a buffer plate is fixedly connected to the right part of the outer surface of the connecting tube, and the bottom of the buffer plate is connected to the inner wall of the lower hopper through an arc buffer spring.

The arc-shaped buffer spring can reduce the buffer force when the material falls, so that the material can fall on the lower conveyor belt relatively smoothly and avoid a large amount of dust. In addition, the arc-shaped sleeve and the arc-shaped rod are used to support the arc-shaped buffer spring to prevent excessive deformation and damage of the arc-shaped buffer spring.

[0022] Compared with the prior art, the utility model has the following beneficial effects:

[0023] 1. By setting up a stirring mechanism, the materials in the discharge hopper are stirred by several stirring rods, which helps the materials to flow more smoothly, reduces the possibility of blockage caused by accumulation of materials in the discharge hopper, and makes the materials discharge more evenly, avoiding uneven discharge. At the same time, the materials can be discharged more effectively, reducing the residual materials in the discharge hopper;

[0024] 2. By setting up a buffer mechanism, when the material is discharged from the discharge funnel to the conveyor belt on the lower layer, it is first buffered by two buffer plates under the elastic force of the arc buffer spring, thereby reducing the impact force of the material when it falls, reducing the impact force on the receiving conveyor belt, and avoiding overall shaking due to impact, thereby ensuring a smooth production process. At the same time, the material falls smoothly, which can reduce dust, avoid a large amount of dust spreading into the air, reduce air pollution, and prevent the material from being broken, deformed or damaged due to impact, thereby maintaining the original quality and integrity of the material.

[0037] See also Figure 1-3 , the utility model provides a technical solution:

[0038] A discharging funnel comprises a lower silo 1, the core structure of which comprises a lower silo 1, a connecting box 2 is fixed on the upper left end of the lower silo 1, a driving groove 3 is opened on the right side of the connecting box 2, a stirring mechanism 4 is fixedly installed on the left end of the connecting box 2, and the stirring mechanism 4 comprises a motor 41, a rotating rod 42 is fixedly installed on the output end of the motor 41 through a coupling, the right end of the rotating rod 42 is keyed and fixed to the middle of a driving gear 43, and the driving gear 43 is meshed and connected with a driven gear 44, thereby ensuring stable transmission of power, a rotating column 45 is fixedly connected to one side of the driven gear 44, and the driven gear 44 is close to one side of the lower silo 1, a rotating cylinder 46 is sleeved and fixed on the outer side of the rotating column 45, and a plurality of stirring rods 47 are staggered and fixedly connected to the outer surface of the rotating cylinder 46, and the staggered distribution makes the stirring more uniform.

[0039] Through the above arrangement, the stirring mechanism 4 is arranged in the connection box 2 to avoid dust falling, make the mechanical parts run more stably, and reduce the maintenance cost. The motor 41 is started, and the motor 41 drives the rotating rod 42 to rotate. Subsequently, the rotating rod 42 drives the driving gear 43 to rotate, and the driving gear 43 further drives the driven gear 44 to rotate. The rotation of the driven gear 44 causes the rotating column 45 to rotate, thereby driving the rotating cylinder 46 to rotate together. This rotation action causes multiple stirring rods 47 to rotate inside the discharge funnel, effectively stirring the material inside.

[0040] See also Figure 1-3 The mounting end of the motor 41 is fixedly connected to the left side of the connecting box 2 by a bolt 8, the rotating rod 42 is connected to the end of the connecting box 2 through an insertion connection and extends to the inside of the driving groove 3, the driving gear 43 and the driven gear 44 are both arranged inside the driving groove 3, and the outer surface of the driving gear 43 and the outer surface of the driven gear 44 are not in contact with the inner wall of the driving groove 3, the end of the driven gear 44 away from the rotating column 45 is rotatably connected to the left groove wall of the driving groove 3 through a bearing, and the end of the rotating column 45 away from the driven gear 44 is movably installed on the right wall of the lower silo 1, and a plurality of stirring rods 47 are located inside the lower silo 1.

[0041] Through the above arrangement, the driving gear 43 and the driven gear 44 are both located in the driving groove 3. Such a design not only protects the gears from external dust, but also ensures the accuracy of meshing. The stirring rod 47 rotates under the drive of the motor 41, so that a plurality of stirring rods 47 can rotate to stir the material inside the discharge funnel, increase the fluidity of the material inside the discharge funnel, avoid its blockage, and improve the smoothness and efficiency of the discharge. First, it promotes a smoother flow of materials and significantly reduces the risk of material accumulation in the funnel and causing blockage; second, it ensures the uniformity of material discharge and avoids the problems that may be caused by uneven discharge; finally, this design more effectively promotes the discharge of materials and reduces the possibility of material residue in the funnel.

[0042] See also Figure 2 and Figure 5 A buffer mechanism 5 is movably installed between the inner front wall and the inner rear wall of the lower material bin 1. The buffer mechanism 5 includes a movable rod 51, a connecting tube 52, a buffer plate 53 and an arc-shaped buffer spring 54. The connecting tube 52 is sleeved and fixed on the outer side of the movable rod 51, and the buffer plate 53 is fixedly connected to the side wall of the connecting tube 52. The two ends of the arc-shaped buffer spring 54 are respectively installed on the bottom of the buffer plate 53 and the inner wall of the lower material bin 1, that is, the two ends of the arc-shaped buffer spring 54 are respectively in contact with the inner wall of the lower material bin 1 and the corresponding bottom of the buffer plate 53.

[0043] Through the above arrangement, when the materials fall, they first fall on the two buffer plates 53, which will be pressed down by the pressure of the materials and squeeze the internal arc buffer springs 54. This design utilizes the elasticity of the arc buffer springs 54 to effectively reduce the impact force of the materials when they fall, so that the materials can fall more smoothly on the conveyor belt of the lower layer. This not only reduces the potential damage to the conveyor belt of the lower layer, but also avoids the dust caused by the falling materials, thereby reducing the pollution to the external environment.

[0044] See also Figure 2 and Figure 5 The front and rear ends of the movable rod 51 are movably connected to the front and rear walls of the lower material bin 1 respectively, and an arc sleeve 55 and an arc rod 56 are welded and fixed to the bottom of the buffer plate 53 and the inner wall of the lower material bin 1 respectively. The arc sleeve 55 and the arc rod 56 are both arc-shaped, and the end of the arc rod 56 away from the inner wall of the lower material bin 1 is slidably connected to the arc sleeve 55, and the arc rod 56 and the arc sleeve 55 are both located on the inner side of the arc buffer spring 54, and the arc sleeve 55 is close to the inner side of the arc buffer spring 54. The arc sleeve 55 supports the arc buffer spring 54 to prevent the arc buffer spring 54 from excessive deformation and damage.

[0045] Through the above arrangement, the buffer plate 53 contacts the falling material and is buffered by the arc buffer spring 54, so that the impact force of the material when it falls is reduced. It can not only provide protection for the conveyor belt of the lower layer to avoid damage caused by continuous impact, but also make the material fall on the conveyor belt of the lower layer relatively smoothly to avoid a large amount of dust.

[0046] See also Figure 1 The feed bin 6 is fixed at the upper end of the lower bin 1, and the feed bin 6 can receive and feed the materials on the upper conveyor belt. The mounting strip 7 is fixed at the front end of the feed bin 6, and bolts 8 are inserted and installed on both sides of the front end of the mounting strip 7.

[0047] Through the above arrangement, the entire discharge funnel can be installed at the discharge port of the upper conveyor belt.

[0048] Working principle: During use, the discharge hopper is firmly mounted at the discharge port of the upper conveyor belt by using bolts 8. The material enters the discharge hopper from the upper conveyor belt through the feed bin 6. The motor 41 is started, and the motor 41 drives the rotating rod 42 to rotate. Subsequently, the rotating rod 42 drives the driving gear 43 to rotate, and the driving gear 43 further drives the driven gear 44 to rotate. The rotation of the driven gear 44 causes the rotating column 45 to rotate, thereby driving the rotating cylinder 46 to rotate together. This rotational action causes multiple stirring rods 47 to rotate inside the discharge hopper, effectively stirring the material inside.

[0049] When the materials fall, they first fall on the two buffer plates 53 , which are pressed down by the pressure of the materials and squeeze the arc-shaped buffer springs 54 inside.
