Description

Technical Field

[0001] The present application relates to the technical field of conveyors, and in particular to an anti-blocking screw conveyor. Background Art

[0002] A screw conveyor is a machine that uses a motor to drive the screw to rotate and push materials to achieve the purpose of transportation. It can transport horizontally, inclined or vertically. It has the advantages of simple structure, small cross-sectional area, good sealing, easy operation, easy maintenance, and convenient closed transportation. It can also stir the materials during the transportation process. At present, screw conveyors are widely used in various industries, such as building materials, chemical industry, electric power, metallurgy, coal, grain and other industries. They are used for horizontal or inclined transportation of powdered, granular and small block materials, such as coal, ash, slag, cement, grain, etc.

[0003] The existing patent (publication number: CN220011037U) discloses an anti-blocking screw conveyor, including a feeding barrel, a left support frame is arranged at the bottom of the left side of the feeding barrel, a left connecting plate is arranged at the top of the left support frame, the left connecting plate is connected to the left end of the feeding barrel, a discharge port is arranged on the side of the left end of the feeding barrel, and a top cover plate is arranged on the top of the feeding barrel.

[0004] The above-mentioned comparative document points out that the utility model is provided with a feeding screw in the feeding barrel, and the feeding screw is rotated by driving the transmission connecting rod driven by the driving motor, thereby spirally feeding the material put into the discharge funnel and falling into the feeding barrel. At the same time, the remaining driving force of the driving motor makes the material entering the feeding barrel looser, thereby avoiding the accumulation of compacted materials under the huge thrust of the feeding screw. The remaining driving force of the driving motor is also effectively utilized to ensure the normal transportation of materials and improve the transportation efficiency of materials. However, when the speed at which the material enters the feeding barrel through the discharge funnel is too fast, the feeding screw may not be able to push the material to the discharge port in time, resulting in the accumulation of materials in the feeding barrel. This accumulation may form a blockage over time, affecting the normal operation of the screw conveyor. At the same time, for materials with larger volumes, the feeding screw may face greater resistance when pushing, resulting in blockage. Utility Model Content

[0005] In response to the shortcomings of the prior art, the present application provides an anti-blocking screw conveyor with advantages such as anti-blocking. It solves the problem that when the material enters the feeding barrel through the discharge funnel too quickly, the feeding screw may not be able to push the material to the discharge port in time, causing the material to accumulate in the feeding barrel. This accumulation may cause blockage over time, affecting the normal operation of the screw conveyor. At the same time, for larger materials, the feeding screw may face greater resistance when pushing, causing blockage.

[0006] To achieve the above-mentioned objectives, the present application provides the following technical solutions: an anti-blocking screw conveyor, comprising a conveying box, a feed port fixedly connected to the upper end of the conveying box, a rotating shaft rotatably connected inside the feed port, a bracket fixedly connected to the lower end of the conveying box, two mirror-distributed motors fixedly connected inside the bracket, two output ends of the two motors fixedly connected to driving wheels, two mirror-distributed screw rods rotatably connected inside the conveying box, two screw rods passing through one side of the conveying box are fixedly connected to two driven wheels corresponding to the driving wheels, and belts are commonly sleeved on the outer walls of the two driven wheels and the driving wheel.

[0007] Through the above scheme, after the material enters the conveying box, the two rotating screw rods push the material along their spiral paths toward the discharge port. Since the two screw rods rotate in opposite directions, they push the material evenly toward the discharge port in the conveying box. At the same time, when the material enters the conveying box through the feed port, two baffles are fixed on the rotating shaft, and the baffles rotate with the rotation of the rotating shaft, thereby controlling the entry speed and flow of the material to prevent large feed and blockage of the conveyor. At the same time, two screw rods are arranged to assist in conveying the material.

[0008] Furthermore, two mirror-distributed slide rails are fixedly connected to the upper end of the conveying box, and a slide plate is slidably connected between the two slide rails.

[0009] Through the above solution, by providing a slide plate and a slide rail, it is convenient to clean and maintain the inside of the conveyor box.

[0010] Furthermore, two connection plates distributed in a mirror image are fixedly connected to one side of the slide plate, and the lower ends of the two connection plates are fixedly connected to a fixing plate.

[0011] Through the above solution, the skateboard can be conveniently fixed by providing the connecting plate and the fixing plate.

[0012] Furthermore, screws are slidably connected in the middle of the two fixing plates, and the screw threads penetrate through the fixing plates and are threadedly connected to one side of the conveying box.

[0013] According to the above solution, the slide plate is fixed by setting screws when it is not disassembled.

[0014] Furthermore, two infrared sensors distributed in a mirror image are fixedly connected to both sides of the feed port, and the probes of the two infrared sensors penetrate the side wall of the feed port and extend into the interior of the feed port.

[0015] Through the above solution, the feed port is monitored by setting up an infrared sensor. When someone puts his hand into the machine, the human body temperature is higher than that of the material, the infrared sensor will sense it and stop the machine to prevent personal injury.

[0016] Furthermore, bearings are fixedly connected on both sides of the feed port, a rotating shaft is fixedly connected between the inner walls of the two bearings, and baffles distributed in a mirror image are fixedly connected on both sides of the rotating shaft.

[0017] Through the above scheme, the feed of the feed port is controlled by setting a baffle to prevent the feed flow from being too large and the machine from being blocked.

[0018] Furthermore, a discharge port is fixedly connected to a side of the conveying box away from the feed port.

[0019] Through the above scheme, the material can be discharged conveniently by setting the discharge port.

[0020] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0021] The anti-clogging screw conveyor has two rotating screw rods that push the materials toward the discharge port along their spiral paths after the materials enter the conveying box. Since the two screw rods rotate in opposite directions, they push the materials evenly toward the discharge port in the conveying box. At the same time, when the materials enter the conveying box through the feed port, two baffles are fixed on the rotating shaft, and the baffles rotate with the rotation of the rotating shaft, thereby controlling the entry speed and flow of the materials to prevent the conveyor from being blocked due to large feed. At the same time, two screw rods are arranged to assist in conveying the materials. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] See also Figure 1 , Figure 2 and Figure 3 In this embodiment, an anti-blocking screw conveyor includes a conveying box 1, a feed port 7 is fixedly connected to the upper end of the conveying box 1, a rotating shaft 9 is rotatably connected to the feed port 7, a bracket 12 is fixedly connected to the lower end of the conveying box 1, two motors 15 are fixedly connected to the bracket 12, and the output ends of the two motors 15 are fixedly connected to driving wheels 16. Two screw rods 13 are rotatably connected to the conveying box 1, and the two screw rods 13 pass through one side of the conveying box 1 and are fixedly connected to two driven wheels 14 corresponding to the driving wheels 16. There is a gap between the two driven wheels 14 and the driving wheel 16. The outer walls of both conveyor boxes are jointly sleeved with a belt 17. After the material enters the conveying box 1, the two rotating screw rods 13 push the material along their spiral paths toward the discharge port 18. Since the two screw rods 13 rotate in opposite directions, they push the material in the conveying box 1 evenly toward the discharge port 18. At the same time, when the material enters the conveying box 1 through the feed port 7, two baffles 11 are fixed on the rotating shaft 9. The baffles 11 rotate with the rotation of the rotating shaft 9, thereby controlling the entry speed and flow rate of the material to prevent the conveyor from being blocked due to large feed. At the same time, two screw rods 13 are arranged to assist in conveying the material.

[0030] See also Figure 1 , Figure 2 and Figure 3, the upper end of the conveying box 1 is fixedly connected to two slide rails 2 distributed in a mirror image, and a slide plate 3 is slidably connected between the two slide rails 2. By setting the slide plate 3 and the slide rail 2, it is convenient to clean and maintain the inside of the conveying box 1. One side of the slide plate 3 is fixedly connected to two connecting plates 4 distributed in a mirror image, and the lower ends of the two connecting plates 4 are fixedly connected to a fixing plate 5. The slide plate 3 is conveniently fixed by setting the connecting plate 4 and the fixing plate 5. The middle parts of the two fixing plates 5 are slidably connected with screws 6. The screw 6 threads penetrate the fixing plate 5 and are threadedly connected to one side of the conveying box 1. The slide plate 3 is fixed by setting the screws 6 when it is not disassembled. Two infrared sensors 8 distributed in a mirror image are fixedly connected on both sides of the feed port 7. Two infrared sensors 8 are fixedly connected to the two sides of the feed port 7. The probes of the external sensor 8 all penetrate the side wall of the feed port 7 and extend into the feed port 7. The feed port 7 is monitored by setting the infrared sensor 8. When someone puts his hand into the machine, the body temperature of the human body is higher than that of the material, and the infrared sensor 8 will sense it, and at the same time stop the machine to prevent personal injury. Bearings 10 are fixedly connected on both sides of the feed port 7, and a rotating shaft 9 is fixedly connected between the inner walls of the two bearings 10. Baffles 11 with mirror-distributed shapes are fixedly connected on both sides of the rotating shaft 9. The feeding of the feed port 7 is controlled by setting the baffle 11 to prevent large feed flow and machine blockage. A discharge port 18 is fixedly connected to the side of the conveying box 1 away from the feed port 7, and the discharge port 18 is provided to facilitate the discharge of materials.

[0031] In this embodiment, after the material enters the conveying box 1, the two rotating screw rods 13 push the material along their spiral paths toward the discharge port 18. Since the two screw rods 13 rotate in opposite directions, they push the material in the conveying box 1 evenly toward the discharge port 18. At the same time, when the material enters the conveying box 1 through the feed port 7, two baffles 11 are fixed on the rotating shaft 9. The baffles 11 rotate with the rotation of the rotating shaft 9, thereby controlling the entry speed and flow rate of the material to prevent large feed and blockage of the conveyor. At the same time, two screw rods 13 are arranged to assist in conveying the material.

[0032] It should be noted that the device can be connected to a fixing frame according to on-site needs.

[0033] The working principle of the above embodiment is as follows: when the device is in use, first start the two motors 15, one of which rotates forward and the other rotates reversely, and they will drive the two driving wheels 16 to rotate respectively. The two driving wheels 16 are connected to the driven wheel 14 through the belt 17, thereby driving the two screw rods 13 to rotate inside the conveying box 1. The two screw rods 13 rotate in opposite directions, but are jointly responsible for conveying the material from the feed port 7 to the discharge port 18. When the material enters the conveying box 1, the two rotating screw rods 13 push the material along their spiral paths toward the discharge port 18. Since the two screw rods 13 rotate in opposite directions, they push the material evenly in the conveying box 1 toward the discharge port 18. At the same time, when the material enters the conveying box 1 through the feed port 7, two baffles 11 are fixed on the rotating shaft 9. The baffles 11 rotate with the rotation of the rotating shaft 9, thereby controlling the entry speed and flow of the material to prevent large feed and blockage of the conveyor. At the same time, two screw rods 13 are arranged to assist in conveying the material to reduce the possibility of blockage of large-volume materials.
