Description

Technical Field

[0001] The present invention relates to the technical field of material conveying, and particularly relates to a high-wear-resistant polyurethane material composite screw feeder. Background Art

[0002] A screw feeder is mainly used for short-distance conveying of powdery and granular materials. Existing screw feeders at home and abroad generally consist of a metal cylinder frame, a screw auger made of carbon steel or wear-resistant cast steel by welding, and a motor reduction box, and are driven by the motor reduction box.

[0003] Regarding a high-wear-resistant polyurethane material composite screw feeder disclosed in the patent with the publication number "CN104003123B", by designing a baffle plate at both the front of the feeding end and the rear of the discharging end of the auger, although it largely avoids the accumulation of materials at the bearing, greatly reduces the wear of the bearing by the materials, and improves the service life of the equipment accessories. However, in the actual use process, due to the relatively high humidity of some materials, they are prone to getting damp and sticking together, forming lumps of different sizes, which are easy to block when put into the feeding port. In addition, they are extremely easy to adhere to the inner wall of the feeding cylinder. These situations not only lead to a significant decrease in the material conveying efficiency, accelerate the equipment wear, but also increase the risk of equipment failure.

[0004] Accordingly, the present application proposes a high-wear-resistant polyurethane material composite screw feeder. Summary of the Invention

[0005] The purpose of the present invention is to solve the disadvantages existing in the prior art, and to propose a high-wear-resistant polyurethane material composite screw feeder.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A high-wear-resistant polyurethane material composite screw feeder includes a working frame platform, a dispersing assembly, a cleaning assembly, and a feeding assembly;

[0008] A feeding cylinder is fixedly installed on the working frame platform. An inlet hopper is connected to the feeding cylinder, and an outlet hopper is connected to the lower part of the feeding cylinder. A screw auger is rotatably connected in the feeding cylinder. A triangular frame is fixedly connected in the working frame platform. Two driven rods are rotatably connected in the working frame platform. Torsion springs are provided at the connections of the two driven rods with the working frame platform. Two driving rods are rotatably connected in the working frame platform;

[0009] The dispersing assembly is used to disperse the materials;

[0010] The cleaning assembly is used to clean the materials adhering to the inner wall of the feeding cylinder;

[0011] The feeding assembly is used to prevent blockage when the materials are output.

[0012] Preferably, the breaking up assembly consists of an operating box, two rollers and two groups of teeth, the operating box is connected above the feed hopper, the two rollers are rotatably connected to the inner wall of the operating box, and the two groups of teeth are fixedly connected to the two rollers.

[0013] Preferably, the cleaning assembly is composed of two groups of second gears, two groups of half gears and a rubber hammer, the two groups of half gears are respectively fixedly connected to two active rods, and the two groups of second gears are respectively fixedly connected to two driven rods.

[0014] Preferably, the unloading assembly consists of a vibrating rod, two rotating rods and two knocking rods. The vibrating rod is fixedly mounted on a tripod, the vibrating rod is arranged in a discharge hopper, the two rotating rods are respectively rotatably connected to the inner wall below the workbench, and the two knocking rods are respectively fixedly connected to the two rotating rods.

[0015] Preferably, the workbench is rotatably connected to a first transmission wheel, the workbench is rotatably connected to two second transmission wheels, two first belts are wrapped around the outside of the first transmission wheel, the two first belts are respectively wrapped around the two second transmission wheels, and the operating box is rotatably connected to two first gears.

[0016] Preferably, a third transmission wheel is fixedly connected to the first gear, a second belt is wound around the third transmission wheel, the second belt is wound around the first transmission wheel, the first transmission wheel is fixedly connected to the auger, and the two second transmission wheels are fixedly connected to two active rods respectively.

[0017] Preferably, the two first gears are respectively fixedly connected to the two rollers, the two groups of teeth are staggered, the inner walls of the workbench are respectively rotatably connected to the two first bevel gears, the two first bevel gears are respectively fixedly connected to connecting rods, the two connecting rods are respectively fixedly connected to the two driven rods, and the two groups of the second gears are respectively meshed with the two groups of half gears.

[0018] Preferably, the two rotating rods are respectively fixedly connected with second bevel gears, the two first bevel gears are respectively meshed and connected with the two second bevel gears, a motor is fixedly installed on the outside of the feeding barrel, and the motor drive shaft is fixedly connected to the auger.

[0019] The present invention has the following beneficial effects:

[0020] By disassembling the components, when the first driving wheel drives the third driving wheel to rotate through the second belt, the third driving wheel drives one of the first gears to rotate, which will cause the other first gear to rotate in the opposite direction, so that the two rollers rotate in opposite directions to each other. The teeth of the rollers will tear and stir the material, effectively breaking up the agglomerated material, ensuring that the material entering the feeding cylinder is in a loose state, avoiding the problem of conveying blockage caused by material agglomeration, and reducing the time and maintenance costs caused by material blockage.

[0021] Through the cleaning component, when the first driving wheel drives the two second driving wheels to rotate through the two first belts, the driving rod will be driven to rotate, and the semi-gear fixed on the driving rod will rotate accordingly. Since the two driven rods are rotatably connected to the inner wall of the working platform and a torsion spring is provided at the connection, the semi-gear will intermittently engage with the second gear during rotation, driving the second gear to rotate, and then driving the rubber hammer to continuously strike the feeding cylinder, thereby knocking off the material adhering to the inner wall of the feeding cylinder and avoiding the decrease in conveying efficiency caused by the long-term adhesion and accumulation of materials.

[0022] Through the feeding component, when the driven rod reciprocates under the action of the torsion spring, the first bevel gear can be driven to drive the second bevel gear to reciprocate, so that the rotating rod reciprocates. The knocking rod fixed on the rotating rod will intermittently knock the vibrating rod, and the blocked material in the discharge hopper will fall down under the vibration generated by the vibrating rod. In this way, the smoothness of material output is improved, the frequency of manual dredging is reduced, and the continuity of production is ensured at the same time.

Specific embodiments

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0033] Embodiment 1:

[0034] Referring to Figure 1 and Figure 2 and Figure 7 and Figure 8 , a high-wear-resistant polyurethane material composite screw feeder includes a working platform 1, a dispersing assembly, a cleaning assembly, and a blanking assembly;

[0035] A feeding cylinder 2 is fixedly installed on the working platform 1. The working platform 1 serves as a bearing foundation, enabling the feeding cylinder 2 to work stably. The feeding hopper 3 is connected above the feeding cylinder 2, and materials can enter the feeding cylinder 2 through this. The discharge hopper 27 is connected below the feeding cylinder 2 for discharging the materials in the feeding cylinder 2. An auger 6 is rotatably connected inside the feeding cylinder 2, and a motor 5 fixed on the outside of the feeding cylinder 2 has its transmission shaft fixedly connected to the auger 6. The operation of the motor 5 drives the auger 6 to rotate, realizing the pushing of materials in the feeding cylinder 2. The feeding cylinder 2, auger 6, feeding hopper 3, and discharge hopper 27 are all made of high-wear-resistant polyurethane composite materials, having characteristics such as high impact resistance, high wear resistance, low friction, and self-lubrication, and are suitable for various harsh working conditions;

[0036] The dispersing assembly is used to disperse the materials;

[0037] The cleaning assembly is used to clean the materials adhered to the inner wall of the feeding cylinder 2;

[0038] The blanking assembly is used to prevent blockage when the materials are output.

[0039] The scattering assembly consists of an operation box 4, two rollers 14 and two groups of teeth 15. The operation box 4 is connected above the feed hopper 3, and the material can smoothly enter the operation box 4 from the feed hopper 3. The two rollers 14 are rotatably connected to the inner wall of the operation box 4 and can rotate freely in the operation box 4. The two groups of teeth 15 are respectively fixed on the two rollers 14 and staggered with each other. When the rollers 14 rotate, the teeth 15 are used to scatter the material. The first transmission wheel 7 rotatably connected on the workbench 1 is fixedly connected to the auger 6. When the motor 5 drives the auger 6 to rotate, the first transmission wheel 7 rotates synchronously. The two first gears 12 rotatably connected on the operation box 4 are respectively fixedly connected to the two rollers 14. The third transmission wheel 9 fixed on one of the first gears 12 is connected to the first transmission wheel 7 through the second belt 13. The first transmission wheel 7 rotates through the second belt 13 to drive the third transmission wheel 9, thereby driving the first gear 12 to rotate, so that the other first gear 12 rotates in the opposite direction, so that the two rollers 14 rotate in the opposite direction to scatter the material.

[0040] In this embodiment, the motor 5 is started to rotate the auger 6, and the auger 6 drives the first transmission wheel 7 to rotate. When the first transmission wheel 7 drives the third transmission wheel 9 to rotate through the second belt 13, the third transmission wheel 9 drives one of the first gears 12 to rotate, which will cause the other first gear 12 to rotate in the opposite direction, so that the two rollers 14 rotate in opposite directions. The teeth 15 of the rollers 14 will tear and stir the material, which can effectively break up the agglomerated material, ensure that the material entering the feeding barrel is in a loose state, avoid the problem of conveying blockage caused by material agglomeration, and reduce the time and maintenance cost caused by material blockage.

[0041] Embodiment 2:

[0042] Different from the first embodiment, Figure 1 , Figure 3 , Figure 4 as well as Figure 6 , this embodiment also has the following further contents:

[0043] Two driven rods 22 are rotatably connected inside the workbench 1. Torsion springs are provided at the connection points between the two driven rods 22 and the workbench 1. The torsion springs can restore the driven rods 22 to their initial positions after rotation. At the same time, two active rods 23 are also rotatably connected inside the workbench 1.

[0044] Two first belts 11 are wound around the outside of the first transmission wheel 7, and the two first belts 11 are respectively wound around two second transmission wheels 8. The rotation of the first transmission wheel 7 is transmitted to the second transmission wheel 8 through belt transmission. The two second transmission wheels 8 are respectively fixedly connected to the two active rods 23, so that the active rod 23 can be driven to rotate when the second transmission wheel 8 rotates.

[0045] The cleaning component consists of two sets of second gears 20, two sets of half gears 21 and a rubber hammer 10. The two sets of half gears 21 are respectively fixed on two driving rods 23. Therefore, when the driving rods 23 rotate, they will drive the half gears 21 to rotate. The two sets of second gears 20 are respectively fixed on two driven rods 22, and the two sets of second gears 20 are respectively meshed with the two sets of half gears 21. When the half gears 21 rotate with the driving rods 23, they will intermittently mesh with the second gears 20, driving the second gears 20 to rotate, and then driving the driven rods 22 to rotate. The rubber hammer 10 is connected to the driven rod 22, and the rotation of the driven rod 22 will drive the rubber hammer 10 to strike the inner wall of the feeding cylinder 2, playing a role in cleaning the adhered materials on the inner wall of the feeding cylinder 2.

[0046] In this embodiment, when the first driving wheel 7 drives the two second driving wheels 8 to rotate through two first belts 11, the driving rods 23 will be driven to rotate, and the half gears 21 fixed on the driving rods 23 will rotate accordingly. Since the two driven rods 22 are rotatably connected to the inner wall of the working platform 1 and torsion springs are provided at the connection points, the half gears 21 will intermittently mesh with the second gears 20 during rotation, driving the second gears 20 to rotate, and then driving the rubber hammer 10 to continuously strike the feeding cylinder 2, thereby shaking off the materials adhered to the inner wall of the feeding cylinder 2 and avoiding the decrease in conveying efficiency caused by the long-term adhesion and accumulation of materials.

[0047] Embodiment Three:

[0048] Refer to Figures 3 - 6 And Figure 8 , compared with Embodiment One and Embodiment Two, in this embodiment:

[0049] The tripod 16 plays a role in quickly dispersing the materials when they fall. Two first bevel gears 24 are respectively rotatably connected to the inner wall of the working platform 1. Two connecting rods 26 are respectively fixedly connected to the two first bevel gears 24, and these two connecting rods 26 are respectively fixedly connected to the two driven rods 22. When the driven rods 22 rotate, they will drive the first bevel gears 24 to rotate through the connecting rods 26.

[0050] The blanking assembly consists of a vibrating rod 17, two rotating rods 18, and two knocking rods 19. The vibrating rod 17 is fixedly installed on the tripod 16 and is located inside the discharge hopper 27, capable of directly acting on the blocked material in the discharge hopper 27. The two rotating rods 18 are respectively rotatably connected to the inner wall of the lower part of the working platform 1. The two knocking rods 19 are respectively fixedly connected to the two rotating rods 18. When the rotating rods 18 rotate, they will drive the knocking rods 19 to move. Second bevel gears 25 are respectively fixedly connected to the two rotating rods 18, and two first bevel gears 24 are respectively meshed with the two second bevel gears 25. When the first bevel gear 24 rotates driven by the driven rod 22, it will drive the rotating rod 18 to rotate through meshing with the second bevel gear 25, thereby enabling the knocking rod 19 to intermittently knock the vibrating rod 17, causing the vibrating rod 17 to vibrate, preventing the material in the discharge hopper 27 from being blocked, and ensuring the smooth output of the material.

[0051] In this embodiment, when the driven rod 22 reciprocally rotates under the action of the torsion spring, it can enable the first bevel gear 24 to drive the second bevel gear 25 to reciprocally rotate, so that the rotating rod 18 reciprocally rotates. The knocking rod 19 fixed on the rotating rod 18 will intermittently knock the vibrating rod 17, and the blocked material in the discharge hopper 27 will fall down under the vibration generated by the vibrating rod 17. In this way, the smoothness of the material output is improved, the frequency of manual dredging is reduced, and the continuity of production is ensured at the same time.

[0052] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
