Description

Technical Field

[0001] The utility model relates to the technical field of feeding hoppers, in particular to an anti-blocking feeding hopper. Background Art

[0002] Tunnel dryer is a kind of equipment that transports materials through conveyor belts and dries the materials during the transportation process. It has an independent electrical box control, is easy to operate, has free adjustment of the conveying speed, runs smoothly, can dry materials for a long time, fully utilizes the effective space, has a large processing capacity, and is more common in industrial production.

[0003] Because the tunnel dryer is used to transport raw materials with high humidity, it is very easy for the raw materials to clog the hopper due to agglomeration when feeding. In addition, after the existing tunnel dryer has been used for a long time, the internal air humidity increases and the temperature is high. The air backflows from the feed port to the hopper, which further aggravates the blockage of the hopper.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and an anti-clogging feeding hopper is proposed. Utility Model Content

[0005] The utility model aims to provide an anti-blocking feeding hopper to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-clogging hopper, comprising a hopper body, a motor is fixed by screws on the outer side of the left end of the hopper body, and the output end of the motor drives a push auger to rotate through gears, the push auger is composed of a central axis and spiral blades welded to the outside, and the outer spiral blades of the push auger are formed by twisting a long and narrow steel plate with a certain thickness into a spiral shape, a gap is left between adjacent spiral blades of the push auger, and the outer spiral blades of the push auger remain close to the bottom of the hopper body groove when rotating.

[0007] Furthermore, a mounting plate is welded and fixed above the hopper body, and mounting holes are provided at four corners of the mounting plate.

[0008] Furthermore, a silo is provided in the middle of the hopper body, and a protective plate is inclinedly provided at the top opening of the silo.

[0009] Furthermore, a discharge channel is welded and fixed on the outer side of the right end of the hopper body, and the discharge channel is horizontally connected to the bottom of the silo.

[0010] Furthermore, a feed inlet is provided at the end of the discharge channel, and a torsion spring seat is fixed above the feed inlet.

[0011] Furthermore, a baffle is rotatably mounted on the outer side of the torsion spring seat, and the outer dimensions of the baffle are larger than the diameter of the feed opening.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. When the utility model is in use, a motor-driven pushing auger is installed at the bottom of the silo, so that the input raw materials fall into the gap between adjacent spiral blades, and are discharged through the inlet at the end of the discharge channel with the continuous rotation of the pushing auger. This design is very suitable for conveying raw materials with high humidity, and can effectively prevent the raw materials from clumping and blocking the inlet, and keep the continuous and smooth discharge of the hopper body.

[0014] 2. When the utility model is in use, a protective plate is obliquely arranged at the top opening of the silo to prevent excessive amount of raw materials from being put in at one time, causing impact on the pushing auger, causing it to deform and lose functionality. In addition, the present application also rotatably installs a baffle plate above the feed port at the end of the discharge channel through a torsion spring seat, which can close the feed port when the hopper body stops feeding, preventing the air with higher humidity and temperature in the tunnel dryer from flowing back into the hopper body, resulting in aggravated raw material agglomeration.

[0019] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0020] like Figures 1 to 3As shown, an anti-blocking feeding hopper includes a hopper body 1, a motor 10 is fixed by screws on the outer side of the left end of the hopper body 1, and the output end of the motor 10 drives a pusher auger 11 to rotate through a gear, the pusher auger 11 is composed of a central shaft and spiral blades welded to the outside, and the outer spiral blades of the pusher auger 11 are twisted into a spiral shape by a long and narrow steel plate with a certain thickness, and there is a gap between adjacent spiral blades of the pusher auger 11, and the outer spiral blades of the pusher auger 11 are kept close to the bottom position of the groove of the hopper body 1 when rotating, and the pusher auger 11 driven by the motor 10 is installed at the bottom of the silo 4, so that the input raw materials fall into the gap between adjacent spiral blades, and are discharged through the feed port 7 at the end of the discharge channel 6 with the continuous rotation of the pusher auger 11. This design is very suitable for the transportation of raw materials with high humidity, and can effectively prevent the raw materials from agglomerating and blocking the feed port 7, so as to keep the continuous and smooth discharge of the hopper body 1;

[0021] like Figure 1 to Figure 2 As shown, a mounting plate 2 is welded and fixed on the top of the hopper body 1, and mounting holes 3 are provided at four corners of the mounting plate 2. A hopper 4 is opened in the middle of the hopper body 1, and a protective plate 5 is obliquely provided at the top opening of the hopper 4. A discharge channel 6 is welded and fixed to the outside of the right end of the hopper body 1, and the discharge channel 6 is horizontally connected to the bottom of the hopper 4. A feeding port 7 is opened at the end of the discharge channel 6, and a torsion spring seat 8 is fixed above the feeding port 7. A baffle 9 is rotatably installed on the outside of the torsion spring seat 8, and the outer size of the baffle 9 is larger than the diameter of the feeding port 7. By obliquely setting the protective plate 5 at the top opening of the hopper 4, it is prevented that the pushing auger 11 is deformed and loses its functionality due to excessive one-time input of raw materials. In addition, the present application also rotatably installs a baffle 9 above the feeding port 7 at the end of the discharge channel 6 through the torsion spring seat 8, so that the feeding port 7 can be closed when the hopper body 1 stops feeding, so as to prevent the air with higher humidity and temperature in the tunnel dryer from flowing back into the hopper body 1, resulting in aggravated raw material cohesion.

[0022] Working principle: When using this anti-clogging hopper, a pusher auger 11 driven by a motor 10 is installed at the bottom of the silo 4, so that the input raw materials fall into the gap between adjacent spiral blades, and are discharged through the inlet 7 at the end of the discharge channel 6 along with the continuous rotation of the pusher auger 11. This design is very suitable for the transportation of raw materials with high humidity, and can effectively prevent the raw materials from clumping and blocking the inlet 7, and maintain the continuous and smooth discharge of the hopper body 1. The protective plate 5 is tiltedly arranged at the top opening of the silo 4 to prevent the pusher auger 11 from being deformed and losing its functionality due to excessive one-time input of raw materials. In addition, the present application also rotatably installs a baffle 9 above the inlet 7 at the end of the discharge channel 6 through a torsion spring seat 8, which can close the inlet 7 when the hopper body 1 stops feeding, to prevent the air with higher humidity and temperature in the tunnel dryer from flowing back into the hopper body 1, which leads to the aggravation of the raw material agglomeration phenomenon.
