Description

Technical Field

[0001] The utility model relates to the technical field of the blanking impeller of a feeder, in particular to a structure of the blanking impeller of a feeder. Background Art

[0002] At present, the feeder on the market adopts a screw-type blanking structure. The screw is injection molded with plastic. Some of the screw shafts are made of stainless steel and some are made of plastic. There is a certain gap between the screw and the material pipe. This screw-type blanking structure often causes the motor to be blocked due to material jamming during use, reducing the service life of the motor and increasing the maintenance cost. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a structure of the blanking impeller of a feeder to solve the problem of material jamming when the feeder discharges materials.

[0004] To achieve the above object, the utility model provides the following technical scheme: a structure of the blanking impeller of a feeder, including a rotating shaft. An impeller mounting shaft is fixedly sleeved on the outer side of the rotating shaft. An impeller assembly is sleeved on the outer side of the impeller mounting shaft. The impeller assembly includes an annular sleeve and blades. The annular sleeve is sleeved on the outer side of the impeller mounting shaft. A plurality of blades are fixedly connected to the outer wall of the annular sleeve. The blades are made of silica gel plates. A tightening ring that abuts against the end of the annular sleeve is threadedly connected to the outer side of one end of the rotating shaft.

[0005] Further, a plurality of installation card slots corresponding to the positions of the blades are opened on the impeller mounting shaft. The installation card slots are open at the top. Ribs are inserted into the installation card slots. The ribs are fixedly connected to the inner wall of the annular sleeve.

[0006] Further, an operation hole is opened in one end of the rotating shaft close to the tightening ring. A U-shaped elastic piece is inserted into the operation hole. Convex blocks are fixedly connected to the outer walls of the two vertical pieces of the U-shaped elastic piece. Fixed slots are opened on both sides of the inner wall of the tightening ring. The fixed slots are communicated with the operation hole. The convex blocks are clamped with the fixed slots.

[0007] Further, the end of the rib located in the installation card slot is chamfered.

[0008] Further, the thickness of the blade near the impeller mounting shaft is greater than the thickness of the blade on the side away from the impeller mounting shaft.

[0009] Further, the number of blades is set to six.

[0010] Further, the end of the convex block located in the fixed slot is chamfered.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] Through the mutual cooperation of the rotating shaft, the impeller mounting shaft, the annular sleeve and several blades, the normal feeding of the feed can be realized. By setting the blades and the annular sleeve as silica gel plates with a certain hardness, when the blades are subjected to resistance during rotation, the blades also produce a certain elastic deformation, thus solving the problem of motor blockage caused by material jamming, so that the feeder does not jam during feeding. At the same time, because the blades have a certain elastic deformation, the wear of the blades can also be reduced. At the same time, because the blades are not jammed, the rotating shaft can rotate smoothly, and the probability of the rotating shaft breaking during rotation is also reduced. Further, the service life of the motor and the product is increased, the maintenance cost is reduced, and the setting of the tightening ring can press the blades against the outside of the annular sleeve to prevent the blades from sliding off the rotating shaft during rotation.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0020] As Figures 1 to 5 shown, a feeding impeller structure of a feeder includes a rotating shaft 1. An impeller mounting shaft 4 is fixedly sleeved on the outer side of the rotating shaft 1. An impeller assembly 2 is sleeved on the outer side of the impeller mounting shaft 4. The impeller assembly 2 includes an annular sleeve 201 and blades 202. The annular sleeve 201 is sleeved on the outer side of the impeller mounting shaft 4. A plurality of blades 202 are fixedly connected to the outer wall of the annular sleeve 201. The blades 202 are arranged as silica gel plates. A tightening ring 3 that abuts against the end of the annular sleeve 201 is threadedly connected to the outer side of one end of the rotating shaft 1.

[0021] As Figures 1 to 5 shown, when the feeding impeller structure in the utility model is in use, the annular sleeve 201, the blade 202 and the rotating shaft 1 can be connected, and then the two ends of the rotating shaft 1 are respectively connected with the motor output end and the bearing in the feeder to realize feeding. The rotating shaft 1 is a stainless steel shaft, and the blade 202 and the annular sleeve 201 are silica gel plates and are integrally formed. When the blade 202 rotates for feeding, since it is a silica gel plate with a certain hardness, it will elastically deform when encountering resistance, thereby solving the problem of motor blockage caused by material jamming, increasing the service life of the motor and the product, and reducing the maintenance cost.

[0022] As Figure 2 、 Figure 4 and Figure 5 shown, a plurality of installation slots 41 corresponding to the positions of the blades 202 are provided on the impeller installation shaft 4. The installation slots 41 are provided with openings at the top. Ribs 203 are inserted in the installation slots 41, and the ribs 203 are fixedly connected to the inner wall of the annular sleeve 201.

[0023] Specifically, when the blade 202 and the rotating shaft 1 need to be connected, the rib 203 can be vertically slidably clamped with the installation slot 41 on the impeller installation shaft 4 outside the rotating shaft 1. The impeller installation shaft 4 and the rotating shaft 1 are integrally formed stainless steel shafts. The installation slot 41 is provided with an opening at the top to facilitate the clamping of the rib 203, and the bottom is sealed to facilitate the limitation of the rib 203. Then, the tightening ring 3 is rotated so that the tightening ring 3 is threadedly connected outside the rotating shaft 1, and the bottom of the tightening ring 3 can be made to abut against the other end of the annular sleeve 201. With this setting, the top of the annular sleeve 201 can be tightened, and even during the rotation of the rotating shaft 1, the rib 203 can be prevented from driving the blade 202 out of the installation slot 41.

[0024] As Figure 1 、 Figure 2 and Figure 4 shown, an operation hole 11 is provided at one end of the rotating shaft 1 close to the tightening ring 3. A U-shaped elastic piece 5 is inserted into the operation hole 11. Convex blocks 51 are fixedly connected to the outer walls of the two vertical pieces of the U-shaped elastic piece 5. Fixing grooves 31 are provided on both sides of the inner wall of the tightening ring 3. The fixing grooves 31 are communicated with the operation hole 11, and the convex blocks 51 are clamped with the fixing grooves 31.

[0025] Specifically, after the tightening ring 3 is screwed tightly with the rotating shaft 1, pinch the U-shaped elastic piece 5 and insert it into the operation hole 11. The U-shaped elastic piece 5 is made of iron sheet and will shrink relatively after being squeezed. At this time, it can smoothly enter the operation hole 11. At the same time, the convex block 51 enters the operation hole 11 under the drive of the U-shaped elastic piece 5 and is clamped with the two fixing grooves 31. With this setting, the tightening ring 3 can be laterally restricted on the rotating shaft 1 by using the U-shaped elastic piece 5 and the convex block 51, which can effectively prevent the tightening ring 3 from rotating backward in threads due to the vibration generated during the rotation of the rotating shaft 1, playing a role in preventing backward movement. At the same time, because the U-shaped elastic piece 5 has elasticity, it will be well clamped in the operation hole 11.

[0026] As Figure 2 and Figure 5 shown, the rib 203 is chamfered at one end located in the installation slot 41. The chamfered rib 203 can be more conveniently inserted into the installation slot 41.

[0027] As Figure 1 , Figure 2 and Figure 5 shown, the thickness of the blade 202 near one end of the impeller mounting shaft 4 is greater than the thickness of the blade 202 on the side away from the impeller mounting shaft 4. By setting the root of the blade 202 to be thick to thin outward, it not only ensures its strength, but also avoids the problem of uneven feeding caused by excessive elastic deformation of the blade 202 after being blocked.

[0028] As Figure 1 , Figure 2 and Figure 5 shown, the number of the blades 202 is set to six. With this setting, the feed can fall more evenly.

[0029] As Figure 3 shown, the end of the convex block 51 located in the fixing groove 31 is chamfered. The chamfered setting can facilitate the better clamping of the convex block 51 with the fixing groove 31.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
