Description

Technical Field

[0001] The utility model relates to the technical field of feeders, in particular to a material-blocking-proof spiral feeder. Background Art

[0002] An elevator is a mechanical equipment used for lifting and feeding materials. It is mainly suitable for the continuous vertical lifting of powdery, granular and small-piece materials. It can be widely used in the lifting of bulk materials in feed mills, flour mills, rice mills, oil mills, starch mills, grain depots, port terminals, etc. of various sizes. The elevator has a wide range of lifting and has few requirements on the type and characteristics of materials. It can not only lift general powdery and small-granular materials, but also lift materials with greater abrasiveness. It has good sealing and less environmental pollution.

[0003] When a large amount of raw materials are put into the hopper, the raw materials at the bottom will be under pressure from the raw materials above, and the raw materials are easy to agglomerate into blocks, causing the raw materials to get stuck at the discharge port, reducing production efficiency.

[0004] A Chinese patent with publication number CN220299482U is proposed in the prior art, comprising a bottom plate, the upper surface of the bottom plate is fixedly connected to the lower surface of the support rod, the upper surface of the support rod is fixedly connected to the surface of the feed hopper, the inner wall of the feed hopper is fixedly connected to the surface of the filter screen, the side of the feed hopper is fixedly connected to the side of the support plate, the upper surface of the support plate contacts the lower surface of the motor, the output end of the motor is fixedly connected to the side of the rotating shaft, the surface of the rotating shaft is fixedly connected to the surface of the stirring blade, the surface of the feed hopper is fixedly connected to the surface of the feed pipe, the surface of the feed pipe is fixedly connected to the surface of the feeding pipe, and the lower surface of the bottom plate is fixedly connected to the upper surface of the support leg. The feeding elevator with anti-stuck material function has a simple structure, is easy to operate, and improves production efficiency. However, it may not be possible to completely break up the hardened raw materials by only using the stirring blades, and some hardened raw materials will still enter, causing blockage. Utility Model Content

[0005] The utility model aims to provide a screw feeder with anti-stuck material function, so as to solve the problems mentioned in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A material-jamming-proof screw feeder comprises a feed hopper and a conveyor body; a feed port is provided at one end of the conveyor body, the feed hopper is fixedly connected above the feed port, the feed hopper is provided with a first filter plate, the first filter plate is fixedly connected to the feed hopper, and the feed hopper is provided with a stirrer; a support plate is fixedly provided at one side of the feed hopper, a stirring motor is fixedly provided above the support plate, and the output end of the stirring motor is fixedly connected to the rotating shaft of the stirrer; a vibrating material structure is provided below the first filter plate, and the vibrating material structure is used to vibrate the raw materials dropped from the first filter plate; a discharge port is provided at the other end of the conveyor body away from the feed hopper.

[0008] When feeding, the raw materials are input from the feed hopper. The raw materials input into the feed hopper will first fall onto the first filter plate, and the stirring motor is started. The stirring motor drives the stirrer to stir the raw materials that fall onto the first filter plate, so that some raw materials that are agglomerated can be stirred and broken up, and the larger agglomerated raw materials will fall from the first filter plate after being broken up; the raw materials after being broken up may still be in small pieces, and a vibrating material structure is provided under the first filter plate. The smaller agglomerated raw materials can be vibrated and dispersed by the action of the vibrating material structure, so that the raw materials can be well dispersed. The raw materials will fall into the conveyor after being acted on by the vibrating material structure, and will be output from the discharge port through the conveyor.

[0009] A further improvement of the technical solution of the utility model is that the agitator is a spiral ribbon agitator rod.

[0010] The above technical solution is adopted, in which two spirally rising stainless steel ribbons are carefully arranged on the periphery of the stirring shaft. The material can be effectively pushed upward during the stirring process, so as to achieve uniform mixing of the material. The stirring shaft and the ribbon are connected by a crosspiece made of stainless steel round steel. These crosspieces are evenly distributed between the stirring shaft and the ribbon, which not only provides strong support, but also can effectively divide the material. When the stirring shaft is driven to rotate by the reduction motor, the crosspiece and the ribbon work together. On the one hand, the material is raised by the pushing action of the ribbon, and on the other hand, the material is effectively divided by the dividing action of the crosspiece, thereby breaking the agglomeration phenomenon in the material and achieving a more uniform stirring and dispersion effect.

[0011] The further improvement of the technical solution of the utility model is that: a plurality of windows are provided on the upper end of the conveyor body. The conveyor body is fixedly connected with a cylinder and a water tank, the upper end of the movable end of the cylinder is fixedly connected with a fixed plate, the fixed plate is fixedly connected with a spray block and a water pipe, the water pipe is communicated with the water tank, the water pipe is communicated with the spray block, and a nozzle is fixedly provided on the spray block.

[0012] The above technical solution is adopted. In this solution, after the raw material transportation is completed, raw materials are likely to remain inside the conveyor body and adhere to the inner wall of the conveyor body, making it difficult to clean. By setting a window and a nozzle, after the raw material transportation is completed, the cylinder is started to drive the fixed plate to fall so that the nozzle falls into the window, and then the water in the water tank is pumped into the water pipe through an external water pump, and the water in the water tank is sprayed out through the nozzle to clean the inside of the conveyor body.

[0013] A further improvement of the technical solution of the utility model is that the nozzle forms an angle of 60 degrees with the horizontal plane.

[0014] By adopting the above technical solution, the raw materials remaining inside the feeder body will generally adhere to the inner wall. By setting the nozzle at an angle of 60 degrees to the horizontal plane, the spraying range of the nozzle is increased, the cleaning range is increased, and incomplete cleaning is prevented.

[0015] The further improvement of the technical solution of the utility model lies in that: the vibrating material structure includes a pad block, which is fixedly connected to the feed hopper; a second filter plate is provided between the pad blocks, the second filter plate is slidably connected to the pad block, one side of the second filter plate is protruding, the protruding part is a pressure plate, a spring is provided between the pad block and the second filter plate, the spring is fixedly connected to the second filter plate and the pad block; a turntable is provided on the side of the upper hopper opposite to the stirring motor, the turntable is fixedly connected to the rotating shaft at one end of the stirrer, and one end of the turntable protrudes to form a knocking rod.

[0016] The above-mentioned technical scheme is adopted. When the stirring motor rotates, it drives the turntable to rotate, and the knocking rod on the turntable will rotate with the turntable. Initially, the knocking rod overlaps with the pressure plate. When the knocking rod rotates, it rotates to squeeze the pressure plate, causing the pressure plate to move downward. The downward movement of the pressure plate will squeeze the spring, causing the second pressure plate to move downward. When the knocking shaft rotates to other positions, the pressure plate is no longer squeezed, and the pressure plate rebounds under the elastic force of the spring, causing the second filter plate to rise, thereby achieving the effect of vibrating the raw materials.

[0017] A further improvement of the technical solution of the utility model is that the end of the knocking rod in contact with the pressing plate is rounded.

[0018] The above technical solution is adopted, in which the end face of the tapping shaft is rounded, so that there will be no large friction when the tapping shaft contacts the pressure plate, thereby reducing the damage when the two collide and increasing the service life.

[0019] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0020] 1. The utility model provides a screw feeder with anti-jamming properties. Raw materials are input from a feed hopper. The raw materials input into the feed hopper will first fall onto a first filter plate. The stirring motor is started. The stirring motor drives the stirrer to stir the raw materials falling onto the first filter plate, so that some agglomerated raw materials can be stirred and broken up. Large agglomerated raw materials will fall from the first filter plate after being broken up. The raw materials after being broken up may still be in small pieces. A vibrating material structure is provided under the first filter plate. Small agglomerated raw materials can be vibrated and broken up by the action of the vibrating material structure, so that the raw materials can be well dispersed. The raw materials will fall into the conveyor after being acted on by the vibrating material structure, and will be output from the discharge port through the conveyor.

[0021] 2. The utility model provides a screw feeder that prevents materials from getting stuck. By setting a window and a nozzle, after the raw material is transported, the cylinder is started to drive the fixed plate to fall so that the nozzle falls into the window, and then the water in the water tank is pumped into the water pipe through an external water pump. The water in the water tank is sprayed out through the nozzle to clean the inside of the conveyor body. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The present invention is further described in detail below in conjunction with the embodiments:

[0030] Example 1

[0031] like Figure 1-5As shown, the utility model provides a material-jamming-proof screw feeder, comprising a feed hopper 1 and a conveyor body 2; a feed port is provided at one end of the conveyor body 2, the feed hopper 1 is fixedly connected above the feed port, the feed hopper 1 is provided with a first filter plate 3, the first filter plate 3 is fixedly connected to the feed hopper 1, and a stirrer 4 is provided on the feed hopper 1; a support plate is fixedly provided at one side of the feed hopper 1, a stirring motor 5 is fixedly provided above the support plate, and an output end of the stirring motor 5 is fixedly connected to a rotating shaft of the stirrer 4; a vibrating material structure is provided below the first filter plate 3, and the vibrating material structure is used to vibrate the raw materials dropped from the first filter plate 3; a discharge port 6 is provided at the other end of the conveyor body 2 away from the feed hopper 1.

[0032] In this embodiment, when feeding, the raw materials are input from the feed hopper 1. The raw materials input into the feed hopper 1 will first fall onto the first filter plate 3, and the stirring motor 5 is started. The stirring motor 5 drives the stirrer 4 to stir the raw materials that fall onto the first filter plate 3, so that some of the raw materials that are agglomerated can be stirred and broken up, and the larger agglomerated raw materials will fall from the first filter plate 3 after being broken up; the raw materials after being broken up may still be in small pieces. A vibrating material structure is provided under the first filter plate 3, and the smaller agglomerated raw materials can be vibrated and dispersed by the action of the vibrating material structure, so that the raw materials can be well dispersed. The raw materials will fall into the conveyor after being acted on by the vibrating material structure, and will be output from the discharge port 6 through the conveyor.

[0033] In this embodiment, preferably, the agitator 4 is a spiral ribbon agitator.

[0034] The device carefully sets two spirally rising stainless steel ribbons on the periphery of the stirring shaft. The materials can be effectively pushed upward during the stirring process, so as to achieve uniform mixing of the materials. The stirring shaft and the ribbon are connected by crosspieces made of stainless steel round steel. These crosspieces are evenly distributed between the stirring shaft and the ribbon, which not only provide strong support but also can effectively divide the materials. When the stirring shaft is driven to rotate by the reduction motor, the crosspieces and the ribbons work together. On the one hand, the materials are raised by the pushing action of the ribbons, and on the other hand, the materials are effectively divided by the dividing action of the crosspieces, thereby breaking the agglomeration phenomenon in the materials and achieving a more uniform stirring and dispersion effect.

[0035] Example 2

[0036] On the basis of Example 1, the utility model provides a technical solution: preferably, a plurality of windows 7 are provided at the upper end of the conveyor body 2. The conveyor body 2 is fixedly connected with a cylinder 8 and a water tank 10, the upper end of the movable end of the cylinder 8 is fixedly connected with a fixed plate 9, the fixed plate 9 is fixedly connected with a spray block and a water pipe, the water pipe is communicated with the water tank 10, the water pipe is communicated with the spray block, and a nozzle 11 is fixedly provided on the spray block.

[0037] In this embodiment, after the raw material transportation is completed, raw materials are likely to remain inside the conveyor body 2 and adhere to the inner wall of the conveyor body 2, making it difficult to clean. By setting the window 7 and the nozzle 11, after the raw material transportation is completed, the cylinder 8 is started to drive the fixed plate 9 to fall so that the nozzle 11 falls into the window 7, and then the water in the water tank 10 is pumped into the water pipe through an external water pump, and the water in the water tank 10 is sprayed out through the nozzle 11 to clean the inside of the conveyor body 2.

[0038] The nozzle 11 is at an angle of 60 degrees to the horizontal plane.

[0039] The raw materials remaining inside the feeder body will generally adhere to the inner wall. By setting the nozzle 11 at an angle of 60 degrees to the horizontal plane, the spraying range of the nozzle 11 is increased, the cleaning range is increased, and incomplete cleaning is prevented.

[0040] Example 3

[0041] like Figure 1-5 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the vibrating material structure includes a pad block 12, and the pad block 12 is fixedly connected to the feed hopper 1; a second filter plate 13 is provided between the pad blocks 12, and the second filter plate 13 is slidably connected to the pad block 12, one side of the second filter plate 13 is protruded, and the protruding part is a pressing plate 14, and a spring 15 is provided between the pad block 12 and the second filter plate 13, and the spring 15 is fixedly connected to the second filter plate 13 and the pad block 12; a turntable 16 is provided on the side of the upper hopper opposite to the stirring motor 5, and the turntable 16 is fixedly connected to the rotating shaft at one end of the agitator 4, and one end of the turntable 16 protrudes to form a knocking rod 17.

[0042] In this embodiment, when the stirring motor 5 rotates, it drives the turntable 16 to rotate, and the knocking rod 17 on the turntable 16 will rotate with the turntable 16. Initially, the knocking rod 17 is overlapped with the pressure plate 14. When the knocking rod 17 rotates, it rotates to squeeze the pressure plate 14, so that the pressure plate 14 moves downward. The downward movement of the pressure plate 14 will squeeze the spring 15, so that the second pressure plate 14 moves downward. When the knocking shaft rotates to other positions, the pressure plate 14 is no longer squeezed. The pressure plate 14 rebounds under the elastic force of the spring 15, so that the second filter plate 13 rises, thereby achieving the effect of vibrating the raw materials.

[0043] The end of the knock rod 17 that contacts the pressing plate 14 is rounded.

[0044] By providing the rounded corners on the end face of the tapping shaft, there will be no significant friction when the tapping shaft contacts the pressure plate 14, thereby reducing damage when the two collide and increasing their service life.

[0045] The following is a detailed description of the working principle of the anti-stuck screw conveyor.

[0046] like Figure 1-5As shown, when feeding, the raw materials are fed from the feeding hopper 1. The raw materials fed into the feeding hopper 1 will first fall onto the first filter plate 3. The stirring motor 5 is started. The stirring motor 5 drives the stirrer 4 to stir the raw materials falling onto the first filter plate 3, so that some agglomerated raw materials can be stirred and broken up. The larger agglomerated raw materials will fall from the first filter plate 3 after being broken up. The broken raw materials may also have some small pieces of raw materials, which will fall from the first filter plate 3 to the second filter plate 13. When the stirring motor 5 rotates, , driving the turntable 16 to rotate, the knocking rod 17 on the turntable 16 will rotate with the turntable 16, initially the knocking rod 17 will overlap with the pressure plate 14, when the knocking rod 17 rotates, it will rotate and squeeze the pressure plate 14, so that the pressure plate 14 moves downward, the pressure plate 14 moving downward will squeeze the spring 15, so that the second pressure plate 14 moves downward, when the knocking shaft rotates to other positions, it will no longer squeeze the pressure plate 14, the pressure plate 14 rebounds under the elastic force of the spring 15, so that the second filter plate 13 rises, thereby achieving the effect of vibrating the raw material. After the raw material is transported, it is easy for the raw material to remain inside the conveyor body 2, adhere to the inner wall of the conveyor body 2, and it is difficult to clean. By setting the window 7 and the nozzle 11, after the raw material is transported, start the cylinder 8, drive the fixed plate 9 to fall, so that the nozzle 11 falls into the window 7, and then use the external water pump to pump the water in the water tank 10 into the water pipe, and the water in the water tank 10 is sprayed out through the nozzle 11 to clean the inside of the conveyor body 2

[0047] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention.
