Technical Field

[0001] The present invention relates to the technical field of mechanical feeding equipment, and particularly to a mechanical transmission feeding device and its use method. Background Art

[0002] A feeding device is a machine used to transport materials and is an indispensable transmission device in light and heavy industries. The screw feeding device is one of the feeding devices. The screw feeding device is divided into two types: a shafted screw conveyor and a non-shafted screw conveyor in terms of the conveying form. Both use rotating screw blades to push the materials for conveying. This makes the screw feeding device commonly used in the processing of some food flours to convey flour.

[0003] When using a screw feeding device to convey powdery raw materials such as flour, usually the powdery raw materials such as flour are first poured into the feed hopper, and then the raw materials fall onto the screw auger through the feed hopper, and then the raw materials are conveyed through the rotation of the screw auger. However, when the powdery raw materials fall into the feed hopper, due to the moisture of the raw materials or excessive raw materials accumulated at the feed inlet, caking and blockage may occur at the bottom of the feed inlet, thus affecting the falling of the raw materials. In view of the above problems, the following solutions are proposed. Summary of the Invention

A fixed block is fixedly connected to the outer wall of the transmission pipe. A second bevel gear is rotatably connected to the inner wall of the fixed block. The outer wall of the second bevel gear is meshed with the outer wall of the first bevel gear. A rotating block is fixedly connected to the outer wall of the second bevel gear. When the motor is powered on and running, it synchronously drives the screw auger to rotate. When the screw auger rotates, it drives the second bevel gear to rotate through the first bevel gear. When the second bevel gear rotates, it drives the rotating block to rotate together.

[0008] Preferably, the stirring and scraping mechanism also includes a rack slidably connected to the inner wall of the feed hopper, a rectangular slide is fixedly connected to the outer wall of the rack, the inner wall of the rectangular slide is rotatably connected to the outer wall of the rotating block, a fixed rod is fixedly connected to the inner wall of the feed hopper, the inner wall of the fixed rod is slidably connected to the outer wall of the rack, a gear block is rotatably connected to the inner wall of the fixed rod, the outer wall of the gear block is meshed with the outer wall of the rack, and a movable adjustment component is fixedly connected to the outer wall of the rack, and when the rotating block rotates, the convex column on its top slides on the inner wall of the rectangular slide, allowing the rack to move back and forth, and when the rack moves back and forth, it drives the gear block to rotate reciprocatingly.

[0009] Preferably, the stirring and scraping mechanism also includes a telescopic rod 1 fixedly connected to the top of the gear block, a rotating rod is rotatably connected at the inner wall of the fixed rod, the bottom of the rotating rod is fixedly connected to the top of the telescopic rod 1, the outer wall of the rotating rod is fixedly connected to the stirring rod, the outer wall of the stirring rod is fixedly connected to the telescopic scraper, the outer wall of the telescopic scraper is rotatably connected to the inner wall of the feed hopper, and the inner wall of the rotating rod is fixedly connected to the extrusion control component. Utilizing the characteristic that the auger rotates, the bevel gear 2 is driven to rotate by the bevel gear 1, and a rotating block is provided on the bevel gear 2. When the motor is energized and running, the auger is synchronously driven to rotate. When the auger rotates, the bevel gear 2 is driven to rotate through the bevel gear 1. When the bevel gear 2 rotates, the rotating block is driven to rotate together, and through its top The convex column slides on the inner wall of the rectangular chute, allowing the rack to move back and forth. When the rack moves back and forth, it drives the gear block to rotate back and forth. When the gear block rotates, the rotating rod is synchronously driven to rotate back and forth through the telescopic rod. When the rotating rod rotates, it drives the stirring rod and the telescopic scraper to rotate back and forth together. Through the operation of the above components, the stirring rod can be made to rotate back and forth inside the feed hopper to stir and break up the incoming powdered raw materials, ensure the uniformity and continuity of the discharge, avoid agglomeration due to moisture or excessive accumulation of the powdered raw materials, resulting in obstruction during discharge and affecting normal discharge. In addition, when the telescopic scraper rotates, it will scrape the powdered raw materials deposited at the bottom of the feed hopper to avoid deposition at the bottom of the feed hopper when there is a lot of powdered raw materials, thereby affecting the discharge speed.

[0010] Preferably, the movable adjustment component includes a piston plate fixedly connected to the outer wall of the rack, the outer wall of the piston plate is slidingly connected to the inner wall of the fixed rod, the inner wall of the fixed rod is fixedly connected to a connecting tube 1, the outer wall of the connecting tube 1 is rotatably connected to the inner wall of the gear block, and the inner wall of the rotating rod is slidably connected to a conical head. When the rack moves inward, the hydraulic oil on one side is squeezed through the piston plate to enter the connecting tube 1. At the same time, when there is a lot of powdered raw material inside the feed hopper, the conical head will be pressed downward and squeeze the hydraulic oil below it.

[0011] Preferably, the mobile adjustment assembly further includes a second connecting pipe fixedly connected to the inner wall of the rotating rod. A perforated partition is slidably connected to the inner wall of the rotating rod. A hydraulic pipe is fixedly connected to the inner wall of the rotating rod. The inner wall of the hydraulic pipe is slidably connected to the outer wall of the perforated partition, and the inner wall of the hydraulic pipe is rotatably connected to the outer wall of the first connecting pipe. When the conical head is pressed and moves downward, it will squeeze the hydraulic oil below it, causing the hydraulic oil to push the perforated partition to move through the second connecting pipe, so that the originally interconnected first connecting pipe and the hydraulic pipe form a closed state.

[0012] Preferably, the mobile adjustment assembly further includes a perforated spring plate slidably connected to the inner wall of the rotating rod. A first through hole is formed in the inner wall of the rotating rod, a second through hole is formed in the inner wall of the rotating rod, and a one-way valve is fixedly connected to the inner wall of the rotating rod. Using the characteristic that the rack will move back and forth as described above, a piston plate is provided. When the rack moves inward, the hydraulic oil on one side of the piston plate is squeezed through the piston plate and enters the first connecting pipe. At the same time, when there is a large amount of powdery raw material in the feed hopper, the conical head will be pressed and move downward, squeezing the hydraulic oil below it, causing the hydraulic oil to push the perforated partition to move through the second connecting pipe, so that the originally interconnected first connecting pipe and the hydraulic pipe form a closed state. When the perforated partition moves, it will squeeze the top of the perforated spring plate, causing it to shrink downward. At this time, the first through hole changes from a closed state to an open state, and the second through hole changes from an open state to a closed state. Then, the hydraulic oil that is squeezed and enters the first connecting pipe will push the spring plate to move through the first through hole. When the spring plate moves, it will squeeze the hydraulic oil on the other side of it, causing the hydraulic oil to enter the first telescopic rod through the connecting hole, making the first telescopic rod extend upward and driving the rotating rod to move upward. When the rack moves outward, the hydraulic oil flows back under the influence of negative pressure, the spring plate returns to its original position, and at the same time the hydraulic oil flows back through the connecting hole, the first telescopic rod contracts and drives the rotating rod to move downward. This cycle repeats, so that when there is a large amount of powdery raw material in the feed hopper, while the stirring rod is stirring, it can also move up and down, increasing the stirring area, promoting the feeding of the powdery raw material, and reducing the adhesion and caking of the powdery raw material at the bottom due to greater pressure.

[0013] Preferably, the moving adjustment assembly further includes a spring plate slidably connected to the inner wall of the rotating rod. A connection hole is provided in the inner wall of the rotating rod. A second telescopic rod is fixedly connected to the outer wall of the hydraulic pipe. The outer wall of the second telescopic rod is fixedly connected to the inner wall of the rotating rod. An annular slider is fixedly connected to the outer wall of the second telescopic rod. The inner wall of the annular slider is slidably connected to the outer wall of the stirring rod. Using the above-mentioned characteristics that the hydraulic oil is pressurized and enters the first connection pipe, when the powdered raw material in the feed hopper is less, the conical head will rebound upward, and the hydraulic oil will flow back through the second connection pipe, driving the perforated partition plate to reset. Since the perforated partition plate resets, the perforated spring plate will rebound upward, the first through hole will close again, and the second through hole will open. When the spring plate resets, the hydraulic oil will pass through the second through hole, pass through the one-way valve and return to the first connection pipe again. At this time, the hydraulic oil will pass through the perforated partition plate and enter the hydraulic pipe, and then continue to enter the second telescopic rod, causing the second telescopic rod to extend outward. When the second telescopic rod extends outward, it will synchronously drive the annular slider to slide outward, so that the annular slider can scrape and clean the outer wall of the stirring rod. Through the operation of the above components, when the powdered raw material in the feed hopper is less, the annular slider can scrape and clean the outer wall of the stirring rod, avoiding the powdered raw material adhering to its outer wall, affecting normal stirring and causing trouble in later cleaning. In addition, when the powdered raw material in the feed hopper is more, the annular slider will stop sliding, avoiding the large pressure generated at the bottom due to the large amount of powdered raw material, causing the annular slider to squeeze the powdered raw material during movement, resulting in caking and affecting the feeding and subsequent transmission.

[0014] Preferably, the extrusion control assembly includes a third connection pipe fixedly connected to the inner wall of the rotating rod. A connection groove is provided in the inner wall of the stirring rod. A U-shaped piston rod is slidably connected to the inner wall of the stirring rod. A spring block is fixedly connected to the outer wall of the U-shaped piston rod. The outer wall of the spring block is slidably connected to the inner wall of the stirring rod. A U-shaped hydraulic groove is provided in the inner wall of the stirring rod. Using the above-mentioned characteristics that when the powdered raw material in the feed hopper is more, the conical head will be pressed downward and move, when the conical head moves downward, it will squeeze the hydraulic oil at its bottom, causing it to enter the connection groove. After the hydraulic oil enters the connection groove, it will push the U-shaped piston rod to move outward. When the U-shaped piston rod moves outward, a negative pressure will be generated in the U-shaped hydraulic groove, causing the hydraulic oil in the telescopic scraper to enter the U-shaped hydraulic groove, and at the same time the telescopic scraper will contract. When the powdered raw material in the feed hopper is less, the conical head will rebound upward, and at the same time the hydraulic oil will flow back. When the hydraulic oil flows back, it will drive the U-shaped piston rod to move inward and squeeze the hydraulic oil in the U-shaped hydraulic groove, causing it to re-enter the telescopic scraper and making the telescopic scraper extend outward. Through the operation of the above components, the telescopic scraper will contract inward when the powdered raw material in the feed hopper is more and extend outward when it is less, avoiding the situation that when the telescopic scraper scrapes and cleans, due to the large amount of powdered material in the feed hopper and the large pressure generated at the bottom, the telescopic scraper will bend or be damaged during rotation, thus affecting the normal operation of the equipment.

[0015] A method for using a mechanical transmission feeding device, comprising the following steps:

[0016] S1: Install the device: Before using the device, first install the device at the required position and connect the power supply of the motor;

[0017] S2: Start the device: When the motor runs, it drives the auger to rotate. When the auger rotates, it drives the second bevel gear to rotate through the first bevel gear. When the second bevel gear rotates, it drives the rotating block to rotate, and the convex column at its top slides on the inner wall of the rectangular chute, enabling the rack to reciprocate back and forth.

[0018] The present invention has the following beneficial effects:

[0019] (1) The present invention utilizes the characteristic that when the auger rotates, it drives the second bevel gear to rotate through the first bevel gear. A rotating block is arranged on the second bevel gear. When the motor is powered on and runs, it synchronously drives the auger to rotate. When the auger rotates, it drives the second bevel gear to rotate through the first bevel gear. When the second bevel gear rotates, it drives the rotating block to rotate together, and the convex column at its top slides on the inner wall of the rectangular chute, enabling the rack to reciprocate back and forth. When the rack moves back and forth, it drives the gear block to rotate reciprocally. When the gear block rotates, it synchronously drives the rotating rod to rotate reciprocally through the first telescopic rod. When the rotating rod rotates, it drives the stirring rod and the telescopic scraper to rotate reciprocally together. Through the operation of the above components, the stirring rod can rotate reciprocally inside the feed hopper, stirring and dispersing the incoming powdery raw materials, ensuring the uniformity and continuity of feeding, avoiding caking caused by the moisture absorption or excessive accumulation of the powdery raw materials, resulting in obstruction during feeding and affecting normal feeding. In addition, when the telescopic scraper rotates, it scrapes the powdery raw materials deposited at the bottom of the feed hopper, preventing sedimentation at the bottom of the feed hopper when there is a large amount of powdery raw materials, thereby affecting the feeding speed.

[0020] (2)The present invention utilizes the above-mentioned characteristic that the rack will move back and forth to set a piston plate. When the rack moves inward, the piston plate squeezes the hydraulic oil on one side of it, causing the hydraulic oil to enter the first connecting pipe. At the same time, when there is a large amount of powdery raw material in the feed hopper, the conical head will be pressed downward and squeeze the hydraulic oil below it, causing the hydraulic oil to push the perforated partition plate to move through the second connecting pipe, so that the originally interconnected first connecting pipe and the hydraulic pipe form a closed state. When the perforated partition plate moves, it will squeeze the top of the perforated spring plate, causing it to shrink downward. At this time, the first through hole changes from a closed state to an open state, and the second through hole changes from an open state to a closed state. Then, the hydraulic oil that is squeezed into the first connecting pipe will push the spring plate to move through the first through hole. When the spring plate moves, it will squeeze the hydraulic oil on the other side of it, causing the hydraulic oil to enter the first telescopic rod through the connecting hole, making the first telescopic rod extend upward and drive the rotating rod to move upward. When the rack moves outward, the hydraulic oil flows back under the influence of negative pressure, the spring plate resets, and at the same time, the hydraulic oil flows back through the connecting hole, the first telescopic rod contracts and drives the rotating rod to move downward. In this way, when there is a large amount of powdery raw material in the feed hopper, while the stirring rod stirs, it can also move up and down, increasing the stirring area, promoting the feeding of the powdery raw material, and reducing the adhesion and caking of the powdery raw material at the bottom due to greater pressure.

[0021] (3)The present invention utilizes the above-mentioned characteristic that the hydraulic oil is pressed into the first connecting pipe. When there is a small amount of powdery raw material in the feed hopper, the conical head will rebound upward, causing the hydraulic oil to flow back through the second connecting pipe and drive the perforated partition plate to reset. Due to the reset of the perforated partition plate, the perforated spring plate will rebound upward, the first through hole closes again, and the second through hole opens. When the spring plate resets, the hydraulic oil will pass through the second through hole, pass through the one-way valve and return to the first connecting pipe again. At this time, the hydraulic oil will pass through the perforated partition plate and enter the hydraulic pipe, and then continue to enter the second telescopic rod, causing the second telescopic rod to extend outward. When the second telescopic rod extends outward, it synchronously drives the annular slider to slide outward, so that the annular slider can scrape and clean the outer wall of the stirring rod. Through the operation of the above components, when there is a small amount of powdery raw material in the feed hopper, the annular slider can scrape and clean the outer wall of the stirring rod, avoiding the powdery raw material adhered to its outer wall from affecting normal stirring and causing trouble in later cleaning. In addition, when there is a large amount of powdery raw material in the feed hopper, the annular slider will stop sliding, avoiding the large pressure generated at the bottom due to the large amount of powdery raw material, so that when the annular slider moves, it will squeeze the powdery raw material and cause it to cake, thus affecting the feeding and subsequent transmission.

[0022] (4) In the present invention, when there is a large amount of powdery raw material in the feed hopper, the conical head will be pressed downward. When the conical head moves downward, it will squeeze the hydraulic oil at its bottom, causing the hydraulic oil to enter the connecting groove. After the hydraulic oil enters the connecting groove, it will push the U-shaped piston rod to move outward. When the U-shaped piston rod moves outward, a negative pressure will be generated in the U-shaped hydraulic groove, causing the hydraulic oil in the telescopic scraper to enter the U-shaped hydraulic groove. At the same time, the telescopic scraper will contract. When there is a small amount of powdery raw material in the feed hopper, the conical head will rebound upward. At the same time, the hydraulic oil will flow back. When the hydraulic oil flows back, it will drive the U-shaped piston rod to move inward and squeeze the hydraulic oil in the U-shaped hydraulic groove, causing the hydraulic oil to re-enter the telescopic scraper and making the telescopic scraper extend outward. Through the operation of the above components, the telescopic scraper will contract inward when there is a large amount of powdery raw material in the feed hopper and extend outward when there is a small amount. This can prevent the telescopic scraper from being bent or damaged during scraping and cleaning when there is a large amount of powdery material in the feed hopper, resulting in a large pressure at the bottom, which may affect the normal operation of the equipment.

When the perforated partition plate 405 moves, it will squeeze the top of the perforated spring plate 407, causing it to shrink downward. At this time, the first through hole 408 changes from a closed state to an open state, and the second through hole 409 changes from an open state to a closed state. Then, the hydraulic oil that has been squeezed into the first connecting pipe 402 will push the spring plate 411 to move through the first through hole 408. When the spring plate 411 moves, it will squeeze the hydraulic oil on the other side of it, causing the hydraulic oil to enter the first telescopic rod 309 through the connecting hole 412, making the first telescopic rod 309 extend upward and driving the rotating rod 310 to move upward. When the rack 305 moves outward, the hydraulic oil flows back under the influence of negative pressure, the spring plate 411 resets, and at the same time, the hydraulic oil flows back through the connecting hole 412, the first telescopic rod 309 contracts and drives the rotating rod 310 to move downward. In this way, when there is a large amount of powdery raw material in the feed hopper 201, while the stirring rod 311 is stirring, it can also move up and down, increasing the stirring area, promoting the feeding of the powdery raw material, and reducing the adhesion and caking of the powdery raw material at the bottom due to greater pressure.

[0048] The moving adjustment component 4 further includes a spring plate 411 slidably connected to the inner wall of the rotating rod 310. A connecting hole 412 is formed in the inner wall of the rotating rod 310. A second telescopic rod 413 is fixedly connected to the outer wall of the hydraulic pipe 406. The outer wall of the second telescopic rod 413 is fixedly connected to the inner wall of the rotating rod 310. An annular slider 414 is fixedly connected to the outer wall of the second telescopic rod 413. The inner wall of the annular slider 414 is slidably connected to the outer wall of the stirring rod 311. By using the above-mentioned feature that the hydraulic oil is pressurized and enters the first connecting pipe 402, when the powdery raw material in the feed hopper 201 is less, the conical head 403 will rebound upward, and the hydraulic oil will flow back through the second connecting pipe 404, driving the perforated partition plate 405 to reset. Since the perforated partition plate 405 resets, the perforated spring plate 407 will rebound upward, the first through hole 408 will close again, and the second through hole 409 will open. When the spring plate 411 resets, the hydraulic oil will pass through the second through hole 409, pass through the one-way valve 410 and return to the first connecting pipe 402 again. At this time, the hydraulic oil will pass through the perforated partition plate 405 and enter the hydraulic pipe 406, and then continue to enter the second telescopic rod 413, causing the second telescopic rod 413 to extend outward. When the second telescopic rod 413 extends outward, it synchronously drives the annular slider 414 to slide outward, so that the annular slider 414 can scrape and clean the outer wall of the stirring rod 311. Through the operation of the above components, when the powdery raw material in the feed hopper 201 is less, the annular slider 414 can scrape and clean the outer wall of the stirring rod 311, avoiding the powdery raw material adhered to its outer wall, affecting normal stirring and causing trouble in later cleaning. In addition, when the powdery raw material in the feed hopper 201 is more, the annular slider 414 will stop sliding, avoiding the large pressure generated at the bottom due to the large amount of powdery raw material, causing the annular slider 414 to squeeze the powdery raw material when moving, resulting in caking and thus affecting the feeding and subsequent transmission.

[0049] The extrusion control assembly 5 includes a third connecting pipe 501 fixedly connected to the inner wall of the rotating rod 310. A connecting groove 502 is formed in the inner wall of the stirring rod 311. A U-shaped piston rod 503 is slidably connected to the inner wall of the stirring rod 311. A spring block 504 is fixedly connected to the outer wall of the U-shaped piston rod 503. The outer wall of the spring block 504 is slidably connected to the inner wall of the stirring rod 311. A U-shaped hydraulic groove 505 is formed in the inner wall of the stirring rod 311. Based on the above, when there is a large amount of powdery raw material in the feed hopper 201, the conical head 403 will be pressed downward. When the conical head 403 moves downward, it will squeeze the hydraulic oil at its bottom, causing the hydraulic oil to enter the connecting groove 502. After the hydraulic oil enters the connecting groove 502, it will push the U-shaped piston rod 503 to move outward. When the U-shaped piston rod 503 moves outward, a negative pressure will be generated in the U-shaped hydraulic groove 505, causing the hydraulic oil in the telescopic scraper 312 to enter the U-shaped hydraulic groove 505, and at the same time, the telescopic scraper 312 will contract. When there is a small amount of powdery raw material in the feed hopper 201, the conical head 403 will rebound upward, and at the same time, the hydraulic oil will flow back. When the hydraulic oil flows back, it will drive the U-shaped piston rod 503 to move inward, and squeeze the hydraulic oil in the U-shaped hydraulic groove 505, causing it to re-enter the telescopic scraper 312, making the telescopic scraper 312 extend outward. Through the operation of the above components, the telescopic scraper 312 will contract inward when there is a large amount of powdery raw material in the feed hopper 201 and extend outward when there is less. This can prevent the telescopic scraper 312 from bending or being damaged when scraping and cleaning, due to the large pressure generated at the bottom of the feed hopper 201 when there is a large amount of powdery material, which may affect the normal operation of the equipment.

[0050] The usage method of the mechanical transmission feeding device includes the following steps:

[0051] S1: Install the equipment: Before using the equipment, first install the equipment at the required position and connect the power supply of the motor 204.

[0052] S2: Start the equipment: When the motor 204 runs, it drives the auger 205 to rotate. When the auger 205 rotates, it drives the second bevel gear 303 to rotate through the first bevel gear 301. When the second bevel gear 303 rotates, it drives the rotating block 304 to rotate, and through the convex column at its top sliding on the inner wall of the rectangular sliding groove 306, the rack 305 can reciprocate back and forth.

[0053] A specific application of this embodiment is: before using the device, first install the device at the required position and turn on the power of the motor 204. When the motor 204 is powered on, it drives the auger 205 to rotate synchronously. When the auger 205 rotates, the bevel gear 1 301 drives the bevel gear 2 303 to rotate. When the bevel gear 2 303 rotates, it drives the rotating block 304 to rotate together, and the convex column at its top slides on the inner wall of the rectangular slide 306, so that the rack 305 can move back and forth. When the rack 305 moves back and forth, it drives the gear block 308 to rotate back and forth. When the gear block 308 rotates, it is synchronously driven by the telescopic rod 1 309. It drives the rotating rod 310 to rotate back and forth. When the rotating rod 310 rotates, it drives the stirring rod 311 and the telescopic scraper 312 to rotate back and forth together. Through the operation of the above components, the stirring rod 311 can be made to rotate back and forth inside the feed hopper 201 to stir and break up the incoming powdered raw materials, thereby ensuring the uniformity and continuity of the material discharge, and avoiding the agglomeration of the powdered raw materials due to moisture or excessive accumulation, which causes obstruction during material discharge and affects normal material discharge. In addition, when the telescopic scraper 312 rotates, it will scrape the powdered raw materials deposited at the bottom of the feed hopper 201 to avoid deposition at the bottom of the feed hopper 201 when there is a lot of powdered raw materials, thereby affecting the material discharge speed.

[0054] Taking advantage of the above-mentioned feature that the rack 305 moves back and forth, a piston plate 401 is set. When the rack 305 moves inward, the piston plate 401 squeezes the hydraulic oil on one side thereof, causing it to enter the connecting pipe 1 402. At the same time, when there is a lot of powdered raw materials inside the feed hopper 201, the conical head 403 will be pressed downward and squeeze the hydraulic oil below it, causing it to push the perforated partition plate 405 to move through the connecting pipe 2 404, so that the connecting pipe 1 402 and the hydraulic pipe 406 that were originally interconnected form a closed state. When the perforated partition plate 405 moves, it squeezes the top of the perforated spring plate 407, causing it to shrink downward. At this time, the through hole 1 408 changes from a closed state to an open state, and the through hole 2 409 changes from an open state to a closed state, and then is squeezed into the connecting pipe 1 40 2, will push the spring plate 411 to move through the through hole 1 408. When the spring plate 411 moves, it will squeeze the hydraulic oil on the other side thereof, causing it to enter the telescopic rod 1 309 through the connecting hole 412, so that the telescopic rod 1 309 extends upward and drives the rotating rod 310 to move upward. When the rack 305 moves outward, the hydraulic oil is affected by the negative pressure and flows back. The spring plate 411 is reset. At the same time, the hydraulic oil flows back through the connecting hole 412, the telescopic rod 1 309 contracts and drives the rotating rod 310 to move downward. This cycle is repeated. When there is a lot of powdered raw materials in the feed hopper 201, the stirring rod 311 can move up and down while stirring, thereby increasing the stirring area, promoting the discharge of the powdered raw materials, and reducing the adhesion and agglomeration of the powdered raw materials at the bottom due to the high pressure.

[0055] Taking advantage of the characteristic that the hydraulic oil is pressured into the first connecting pipe 402 as described above, when there is less powdery raw material inside the feed hopper 201, the conical head 403 will rebound upward, and the hydraulic oil will flow back through the second connecting pipe 404, driving the perforated partition plate 405 to reset. Since the perforated partition plate 405 resets, the perforated spring plate 407 will rebound upward, the first through hole 408 closes again, and the second through hole 409 opens. When the spring plate 411 resets, the hydraulic oil will pass through the second through hole 409, pass through the one-way valve 410 and return to the first connecting pipe 402 again. At this time, the hydraulic oil will pass through the perforated partition plate 405 and enter the hydraulic pipe 406, and then continue to enter the second telescopic rod 413, causing the second telescopic rod 413 to extend outward. When the second telescopic rod 413 extends outward, it will synchronously drive the annular slider 414 to slide outward, so that the annular slider 414 can scrape and clean the outer wall of the stirring rod 311. Through the operation of the above components, when there is less powdery raw material in the feed hopper 201, the annular slider 414 can scrape and clean the outer wall of the stirring rod 311, avoiding the powdery raw material adhering to its outer wall, affecting normal stirring and causing trouble in later cleaning. In addition, when there is more powdery raw material in the feed hopper 201, the annular slider 414 will stop sliding, avoiding the large pressure generated at the bottom due to more powdery raw material, causing the annular slider 414 to squeeze the powdery raw material during movement, resulting in caking and thus affecting the feeding and subsequent transmission. When the conical head 403 moves downward, it will squeeze the hydraulic oil at its bottom, causing it to enter the connecting groove 502. After the hydraulic oil enters the connecting groove 502, it will push the U-shaped piston rod 503 to move outward. When the U-shaped piston rod 503 moves outward, it will create a negative pressure in the U-shaped hydraulic groove 505, causing the hydraulic oil in the telescopic scraper 312 to enter the U-shaped hydraulic groove 505, and at the same time the telescopic scraper 312 contracts. When there is less powdery raw material in the feed hopper 201, the conical head 403 will rebound upward, and at the same time the hydraulic oil flows back. When the hydraulic oil flows back, it drives the U-shaped piston rod 503 to move inward and squeezes the hydraulic oil in the U-shaped hydraulic groove 505, causing it to re-enter the telescopic scraper 312, making the telescopic scraper 312 extend outward. Through the operation of the above components, the telescopic scraper 312 contracts inward when there is more powdery raw material in the feed hopper 201 and extends outward when there is less, avoiding the situation that when the telescopic scraper 312 scrapes and cleans, due to more powdery substances in the feed hopper 201, the pressure generated at the bottom is large, causing the telescopic scraper 312 to bend or be damaged during rotation, thus affecting the normal operation of the equipment.
