Description

Technical Field

[0001] This utility model belongs to the technical field of feeding devices, and in particular relates to an automatic control device for continuous feeding speed. Background Technology

[0002] According to the published patent CN203095059U, an automatic control feeding device is provided. The end of the horizontal conveyor belt is equipped with a sensor to detect the quality of the coal. This sensor is connected to a PLC control system, effectively controlling the coal conveying volume, making the coal conveying more stable and continuous. It also ensures that the drum drying effect remains within the optimal range, maximizing the efficiency of the drum drying process. This achieves automatic control of the conveying volume adjustment, saving labor and indirectly reducing production costs. However, it still has the following shortcomings:

[0003] After completion, the aforementioned equipment simply uses sensors to control the conveyor belt speed. However, due to the overly simplistic conveyor belt method, the amount of material being conveyed cannot be significantly adjusted, leading to reduced conveying efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an automatic control device for continuous feeding speed. Through the feeding mechanism and auxiliary mechanism, it solves the problem that the conveying efficiency is reduced because the conveying method of the conveyor belt is too simple and the amount of conveyed material cannot be adjusted significantly.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an automatic control device for continuous feeding speed, including a base plate, and a support block is fixedly connected to the top outer wall of the base plate;

[0007] The outer wall of the base plate is provided with a feeding mechanism, which includes a discharge bin. The outer wall of the discharge bin is fixedly connected to the outer wall of the base plate. A discharge hopper is fixedly connected to the bottom outer wall of the discharge bin. A connecting pipe is fixedly connected to the bottom outer wall of the discharge hopper. A motor is fixedly connected to the inner wall of the support block. The output of the motor is fixedly connected to a connecting shaft via a coupling. A turbine blade is fixedly connected to the outer wall of the connecting shaft. A gear is fixedly connected to the outer wall of the end of the connecting shaft away from the motor. A ring rack meshes with the outer wall of the gear. An arc-shaped scraper is fixedly connected to the outer wall of the ring rack. A fixing ring is fixedly connected to the outer wall of the discharge bin. A discharge plate is fixedly connected to the bottom of the inner wall of the fixing ring. An auxiliary mechanism is provided on the outer wall of the connecting shaft.

[0008] Furthermore, a collection box is slidably connected to the bottom outer wall of the discharge plate, the outer wall of the connecting pipe is fixedly connected to the outer wall of the discharge bin, the outer wall of the connecting shaft is rotatably connected to the inner wall of the connecting pipe, and the collection box is slidably connected to the inner wall of the bottom plate.

[0009] Furthermore, the auxiliary mechanism includes a first pulley, the inner wall of which is fixedly connected to the outer wall of the connecting shaft, a belt is drivenly connected to the inner wall of the first pulley, a second pulley is drivenly connected to the outer wall of the belt away from the first pulley, the outer wall of the second pulley is rotatably connected to the outer wall of the support block, a connecting plate is fixedly connected to the outer wall of the second pulley, and a positioning shaft is fixedly connected to the outer wall of the connecting plate.

[0010] Furthermore, a connecting rod is rotatably connected to the outer wall of the positioning shaft, a positioning rod is rotatably connected to the outer wall of the connecting rod away from the positioning shaft, and a slider is rotatably connected to the outer wall of the other end of the positioning rod.

[0011] Furthermore, an extension plate is fixedly connected to the outer wall of the slider on the side away from the positioning rod, and a filter plate is rotatably connected to the outer wall of the extension plate.

[0012] Furthermore, the inner wall of the discharge bin is slidably connected to the outer wall of the filter plate, and a connecting rod is fixedly connected to the outer wall of the filter plate.

[0013] Furthermore, the outer wall of the connecting rod is rotatably connected to the inner wall of the discharge bin, and a plurality of limiting shells are fixedly connected to the outer wall of the discharge bin, with sliding rods fixedly connected to the bottom of the inner walls of the plurality of limiting shells.

[0014] Furthermore, the outer wall of the slide rod is slidably connected to the inner wall of the slider, a resistance spring is fixedly connected to the top outer wall of the slider, the outer wall of the resistance spring is fixedly connected to the inner wall of the limiting shell, and a detector is fixedly connected to the inner wall of the discharge bin.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model incorporates a connecting shaft and turbine blades. The rotation of the connecting shaft drives the turbine blades to rotate inside the connecting pipe. By controlling the rotation direction of the turbine blades in advance, the turbine blades can propel objects to move. Once the objects have moved a certain distance, they flow through the holes at the bottom of the connecting pipe onto the discharge plate at the bottom, and then through the holes in the discharge plate to be delivered into the collection box. This achieves the goal of using the rotation of the turbine blades to propel materials onto the discharge plate, preventing the problem of reduced conveying efficiency caused by the overly simple conveying method of the conveyor belt, which cannot significantly adjust the amount of material being conveyed.

[0017] 2. This utility model incorporates a slider and a filter plate. During the movement of the connecting rod, the positioning rod moves, simultaneously driving the slider. A limiting shell restricts the slider's movement. The slider's movement also drives the extension plate and filter plate, causing the filter plate to rotate around the inside of the discharge hopper. The slider's range of motion is limited by the sliding rod, achieving a back-and-forth vibration of the filter plate by the slider, thus breaking up large pieces of material. This prevents multiple large pieces of material of different particle sizes from moving simultaneously during the discharge process and blocking the discharge hole, thus hindering the device's normal discharge and affecting work efficiency.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] Please see Figure 1-5 As shown, this utility model is an automatic control device for continuous feeding speed, including a base plate 1, and a support block 101 is fixedly connected to the top outer wall of the base plate 1;

[0029] A feeding mechanism 2 is provided on the outer wall of the base plate 1. The feeding mechanism 2 includes a discharge bin 201, the outer wall of which is fixedly connected to the outer wall of the base plate 1. A discharge hopper 204 is fixedly connected to the bottom outer wall of the discharge bin 201. The discharge hopper 204 is used to feed the material in the discharge bin 201 into the connecting pipe 205 below. The bottom outer wall of the discharge hopper 204 is fixedly connected to the connecting pipe 205. A motor 202 is fixedly connected to the inner wall of the support block 101. When the motor 202 is started, the output of the motor 202 is fixedly connected to a connecting shaft 203 via a coupling. A turbine blade 206 is fixedly connected to the outer wall of the connecting shaft 203. The rotation of the turbine blade 206 pushes the material to move. A gear 207 is fixedly connected to the outer wall of the end of the connecting shaft 203 away from the motor 202. A ring rack 209 meshes with the outer wall of the gear 207. Gear 207 meshes with an annular rack 209, causing gear 207 to push the annular rack 209 to slide around the inside of the fixed ring 208. An arc-shaped scraper 210 is fixedly connected to the outer wall of the annular rack 209. A fixed ring 208 is fixedly connected to the outer wall of the discharge bin 201. A discharge plate 211 is fixedly connected to the bottom of the inner wall of the fixed ring 208. The rotation of the annular rack 209 pushes the arc-shaped scraper 210 to slide around the surface of the discharge plate 211. An auxiliary mechanism 3 is provided on the outer wall of the connecting shaft 203. A collection box 212 is slidably connected to the bottom outer wall of the discharge plate 211. The material is collected through the collection box 212. The outer wall of the connecting pipe 205 is fixedly connected to the outer wall of the discharge bin 201. The outer wall of the connecting shaft 203 is rotatably connected to the inner wall of the connecting pipe 205. The collection box 212 is slidably connected to the inner wall of the bottom plate 1.

[0030] Auxiliary mechanism 3 includes a first pulley 301, the inner wall of which is fixedly connected to the outer wall of connecting shaft 203. Connecting shaft 203 drives the first pulley 301 to rotate. A belt 302 is drivenly connected to the inner wall of the first pulley 301. A second pulley 303 is drivenly connected to the outer wall of the end of belt 302 away from the first pulley 301. Through the connection of feeding mechanism 2, the first pulley 301 and the second pulley 303 are driven to rotate. The outer wall of the second pulley 303 is rotatably connected to the outer wall of support block 101. A connecting plate 304 is fixedly connected to the outer wall of the second pulley 303. A positioning shaft 305 is fixedly connected to the outer wall of the connecting plate 304. A connecting rod 306 is rotatably connected to the outer wall of the positioning shaft 305. Because the positioning shaft 305 is confined to the outermost side of the connecting plate 304, the positioning shaft 305... 5. The rotation range of the connecting rod 306 is greater than the rotation area of ​​the connecting plate 304. The outer wall of the end of the connecting rod 306 away from the positioning shaft 305 is rotatably connected to the positioning rod 307. The outer wall of the other end of the positioning rod 307 is rotatably connected to the slider 308. The rotation of the connecting rod 306 pushes the positioning rod 307 to move, while simultaneously driving the slider 308 to move. The outer wall of the slider 308 away from the positioning rod 307 is fixedly connected to the extension plate 309. The outer wall of the extension plate 309 is rotatably connected to the filter plate 310. The slider 308 pushes the extension plate 309 to move the filter plate 310, while simultaneously driving the connecting rod 311 to rotate around the inside of the discharge bin 201. The inner wall of the discharge bin 201 is slidably connected to the outer wall of the filter plate 310. The outer wall of the filter plate 310 is fixedly connected to the connecting rod 311.

[0031] The outer wall of the connecting rod 311 is rotatably connected to the inner wall of the discharge bin 201. Several limiting shells 312 are fixedly connected to the outer wall of the discharge bin 201, which limit the movement range of the slider 308. A sliding rod 313 is fixedly connected to the bottom of the inner wall of the several limiting shells 312. The outer wall of the sliding rod 313 is slidably connected to the inner wall of the slider 308. A resistance spring 314 is fixedly connected to the top outer wall of the slider 308. As the slider 308 moves along the outside of the sliding rod 313, it squeezes the resistance spring 314. The elasticity of the resistance spring 314 helps the slider 308 rebound. The outer wall of the resistance spring 314 is fixedly connected to the inner wall of the limiting shell 312. A detector 315, model Ningbo Keli DLSF series, is fixedly connected to the inner wall of the discharge bin 201. It can detect the torque changes of key components such as the filter plate vibration motor and turbine blade drive shaft in real time, provide material resistance feedback for the system, and realize intelligent speed regulation and fault warning.

[0032] One specific application of this embodiment is:

[0033] When the operator needs to use the equipment, the motor 202 is started, causing the connecting shaft 203 to rotate, which in turn drives the first pulley 301 to rotate. The belt 302 connects the first pulley 301 and the second pulley 303, causing both to rotate simultaneously. The rotation of the second pulley 303 drives the connecting plate 304 to rotate, which in turn moves the positioning shaft 305. Since the positioning shaft 305 is fixed to the outermost part of the connecting plate 304, its rotation simultaneously pushes the connecting rod 306 to move, and the rotation range of the connecting rod 306 is greater than... During the movement of the connecting rod 306, the connecting plate 304 pushes the positioning rod 307 to move, simultaneously pushing the slider 308 to move. The limiting shell 312 restricts the movement of the slider 308. During the movement of the slider 308, the extension plate 309 moves, simultaneously moving the filter plate 310. The filter plate 310 then drives the connecting rod 311 to rotate around the inside of the discharge bin 201. During the movement of the slider 308, the sliding rod 313 restricts the range of movement of the slider 308, while simultaneously allowing the slider 308 to compress the resistance spring 314 above. The elasticity of the resistance spring 314 increases the rebound force of the slider 308. This increases the swaying amplitude of the filter plate 310. Similarly, on the other side of the filter plate 310, the elasticity of the two resistance springs 314 at both ends of the filter plate 310 increases the vibration frequency. Simultaneously, the detector 315 can detect the vibration frequency of the filter plate 310 and automatically adjust the speed of the motor 202. Objects passing through the filter plate 310 can flow through the discharge hopper 204 into the connecting pipe 205 below. The rotation of the connecting shaft 203 drives the turbine blades 206 to rotate inside the connecting pipe 205. By controlling the rotation direction of the turbine blades 206 in advance, the turbine blades 206 can push the object forward through rotation. After reaching a certain distance, the material will flow through the holes at the bottom of the connecting pipe 205 onto the discharge plate 211 at the bottom, and then through the holes in the discharge plate 211 to the inside of the collection box 212. During the rotation of the connecting shaft 203, the connecting shaft 203 will drive the outermost gear 207 to rotate. Since the gear 207 meshes with the ring rack 209, the gear 207 pushes the ring rack 209 to slide around the inside of the fixed ring 208. During the movement of the ring rack 209, it will drive the arc scraper 210 to slide on the surface of the discharge plate 211. The rotation of the arc scraper 210 is used to control the discharge speed and quantity of the material.
