Further, the first linkage part is a conical end formed at the end part of the main shaft, the second linkage part is a conical sleeve formed on the material stirring impeller, the conical sleeve is rotatably assembled at the conical end, and a gap is formed between the conical sleeve and the conical end in the axial direction of the main shaft.

Furthermore, a limiting part protruding in the radial direction of the end face is formed on the conical end, and the conical sleeve is sleeved on the conical end and limited by the limiting part.

Further, the limiting part and the conical end are integrally formed or detachably connected to the end part of the conical end.

Furthermore, the conical sleeve is provided with a limiting groove for accommodating the limiting part.

Further, the blades of the stirring impeller extend along the radial direction of the conical sleeve and are obliquely connected to the periphery of the conical sleeve at an included angle with the horizontal direction.

Further, the blades extend away from the conical sleeve along the radial direction of the conical sleeve and are bent towards the downstream of the rotation direction of the stirring impeller.

Another aspect of the present invention provides a material conveying device, including: the feeder comprises the feeder and the material barrel, wherein the material barrel is used for receiving materials of the feeder, and a material stirring impeller of the feeder extends into the material barrel.

Based on the structure, the invention can realize the technical effects that:

1. the feeder comprises a feeding pipe and a main shaft arranged in the feeding pipe, wherein a material stirring impeller is arranged at a position, close to a discharging position, of the main shaft, the material stirring impeller is in flexible connection with the main shaft, when a material accumulation angle in a charging barrel is accumulated to the position of the material stirring impeller, the material stirring impeller is lifted by the material on the accumulation angle, so that a second linkage piece on the material stirring impeller is in press fit with a first linkage piece at the end part of the main shaft, the press fit material stirring impeller rotates along with the main shaft, the rotating material stirring impeller blades stir the material on the accumulation angle to a blade tip part of the material stirring impeller blades, and the material stirred to the blade tip falls into an area, close to the inner wall of the charging barrel and not filled, in the charging barrel, so that the material accumulation angle is automatically removed, the material in the charging barrel is leveled, and the space in.

2. When the feeder of the material conveying device is in an initial state and the materials with the stacking angle are not stacked to the conical sleeve, gaps exist between the conical surfaces of the conical sleeve and the conical end, the main shaft does not transmit power to the conical sleeve, namely, the material shifting impeller does not rotate, when the materials at the stacking angle are stacked to the conical sleeve, the conical sleeve is lifted up and moves upwards under the action of the materials, the conical sleeve is pressed against the conical end, the conical surfaces of the conical sleeve and the conical sleeve are in close contact to form linkage, at the moment, the main shaft transmits power to the conical sleeve through the conical surface in close contact with the conical sleeve, so that the material shifting impeller rotates, when the material shifting impeller pulls out the materials at the moment, the material shifting impeller moves downwards under the action of gravity, the material shifting impeller after the downward movement is separated from the linkage state with the main shaft, the material stirring impeller is prevented from forming an electric fan to blow out the materials in the charging barrel by rotating the stirring impeller at a low speed under the inertia effect. It should be noted that the material stirring impeller and the main shaft are always in the state of the pressing fit, separation, pressing fit and separation in the whole material stirring process, so that the rotating speed of the material stirring impeller is always lower than that of the main shaft (the main shaft is provided with a screw for conveying materials, so that the rotating speed cannot be too slow), and the condition that the materials are blown out of the charging barrel due to the fact that the rotating speed of the material stirring impeller is too fast is avoided. Further, when the charging barrel is to be filled, the driving motor of the main shaft is closed, the main shaft stops rotating, at the moment, no material is output from the feeding pipe, the material stirring impeller continues to rotate and stir the material under the action of inertia, along with the complete floating of the material in the charging barrel, the blocking force generated by the leveled material in the charging barrel to the rotation of the material stirring impeller is gradually larger than the rotating force of the material stirring impeller under the action of inertia, and the material stirring impeller stops automatically. The soft connection relation of the material stirring impeller and the main shaft controls the rotating speed of the material stirring impeller to prevent materials from being blown out of the charging barrel, and meanwhile, the same driving motor outputs two different rotating speeds through the soft connection relation, so that the material stirring impeller does not need to be additionally and independently provided with a driving motor and a corresponding driving mechanism, the cost is reduced, and the energy is saved.

Example 1

As shown in fig. 1 to 3, the present embodiment provides a feeder, which includes a main shaft 1 and a feeding member 2 driven by the main shaft 1, where the feeding member 2 in this example is a vertically arranged feeding pipe and a main shaft 1 rotatably disposed in the feeding pipe, a material stirring impeller 3 is configured at one end of the main shaft 1 near a discharging position, the material stirring impeller 3 is assembled to the main shaft 1 by a flexible connection assembly, the flexible connection assembly includes a first linkage member located at an end of the main shaft 1 and a second linkage member rigidly connected to the material stirring impeller 3, the first linkage member and the second linkage member are relatively rotatably assembled, the material stirring impeller 3 drives the second linkage member to press against the first linkage member when moving toward the main shaft 1 under an external force, and when the first linkage member and the second linkage member are pressed, power of the main shaft 1 is transmitted to the material stirring impeller 3 so that the material stirring impeller 3 rotates.

The feeder in this embodiment includes a feeding pipe and a spindle 1 disposed in the feeding pipe, a material stirring impeller 3 is disposed at a position of the spindle 1 close to a discharging position, the material stirring impeller 3 is flexibly connected with the spindle 1, when a material stacking angle in a charging barrel 4 is stacked to the material stirring impeller 3, the material stirring impeller 3 can be lifted by the material on the stacking angle to enable a second linkage member on the material stirring impeller 3 to be in press fit with a first linkage member at the end of the spindle 1, the material stirring impeller 3 after being in press fit rotates along with the spindle 1, a blade 31 of the material stirring impeller 3 after rotating stirs the material on the stacking angle to a blade tip part of the blade 31 of the material stirring impeller 3, at this time, the material stirred to the blade tip falls into an area which is close to the inner wall of the charging barrel 4 and is not filled, so as to automatically remove the material stacking angle, the material in the charging barrel 4 is leveled, and the inner space of the.

In a preferred embodiment of the present invention, the first linkage member is a conical end 11 formed at an end portion of the main shaft 1, the second linkage member is a conical sleeve 32 formed on the stirring impeller 3, and the conical sleeve 32 is rotatably fitted to the conical end 11 with a gap formed therebetween in the axial direction of the main shaft 1. In the initial feeding state, when the material of the accumulation angle is not accumulated to the conical sleeve 32, a gap exists between the conical surfaces of the conical sleeve 32 and the conical end 11, the main shaft 1 does not transmit power to the conical sleeve 32, that is, the material stirring impeller 3 does not rotate, when the material at the stacking angle is stacked to the conical sleeve 32, the conical sleeve 32 is lifted up and moved upwards under the action of the material, so that the conical sleeve 32 is pressed against the conical end 11, the conical surfaces of the conical sleeve and the conical end are in close contact to form linkage, at the moment, the main shaft 1 transmits power to the conical sleeve 32 through the conical surface in close contact with the conical sleeve and then the material stirring impeller 3 rotates, when the material poking impeller 3 pokes out the material at the moment, the material poking impeller 3 moves downwards under the action of gravity, the material poking impeller 3 which moves downwards is separated from the linkage state with the main shaft 1, the material stirring impeller 3 is prevented from forming an electric fan to blow out the materials in the charging barrel 4 by rotating the stirring impeller slowly under the inertia effect. It should be noted that the material stirring impeller 3 and the main shaft 1 are always in the state of the tight fit, separation, tight fit and separation in the whole material stirring process, so that the rotating speed of the material stirring impeller 3 is always lower than that of the main shaft 1 (the rotating speed cannot be too slow because the main shaft 1 is provided with a screw for conveying materials), and the condition that the materials are blown out of the charging barrel 4 due to too fast rotating speed of the material stirring impeller 3 is avoided. Further, when the charging barrel 4 is to be filled, the driving motor of the main shaft 1 is turned off, the main shaft 1 stops rotating, at this time, no material is output from the feeding pipe, the material stirring impeller 3 continues to rotate and stir the material under the action of inertia, along with the complete floating of the material in the charging barrel 4, the blocking force generated by the leveled material in the charging barrel 4 to the rotation of the material stirring impeller 3 is gradually larger than the rotating force of the material stirring impeller 3 under the action of inertia, and the material stirring impeller 3 stops automatically. The soft connection relation between the material stirring impeller 3 and the main shaft 1 controls the rotating speed of the material stirring impeller 3 to prevent materials from being blown out of the charging barrel 4, and meanwhile, the same driving motor outputs two different rotating speeds due to the soft connection relation, so that the material stirring impeller 3 does not need to be additionally and independently configured with a driving motor and a corresponding driving mechanism, the cost is reduced, and the energy is saved.

In order to prevent the conical sleeve 32 from coming off the conical end 11 of the spindle 1, the conical end 11 is formed with a limiting portion 12 protruding in the end surface radial direction, in this embodiment, the limiting portion 12 is configured as a circular bump, and the circular bump limits the conical sleeve 32 sleeved on the conical end 11 to prevent the conical sleeve 32 from coming off the spindle 1. When the material at the stacking angle is not stacked at the conical sleeve 32, the conical sleeve 32 falls to the lowest position of the main shaft 1 under the action of gravity, a gap is formed between the conical sleeve 32 falling to the lowest position of the main shaft 1 and the conical end 11 in the axial direction of the main shaft 1, and the conical sleeve 32 is limited by the limiting part 12 and cannot fall off from the conical end 11 of the main shaft 1.

The stopper portion 12 in this example is integrally formed with the conical end 11 or is detachably connected to the end of the conical end 11, optionally by bolting. The stirring impeller 3 of the feeder in the embodiment needs to be matched with the charging barrel 4, the maximum diameter of the stirring impeller 3 is slightly smaller than the inner diameter of a receiving opening of the charging barrel 4 in the optimal state, and the arrangement of the detachably connected limiting part 12 can enable the feeder in the embodiment to be more convenient to match the charging barrels 4 of different specifications and sizes to realize automatic stacking angle removal.

In a preferred embodiment of the present embodiment, the conical sleeve 32 is formed with a stopper groove 33 for receiving the stopper portion 12.

In order to make the stirring impeller 3 stir more material at the stacking angle, the blades 31 of the stirring impeller 3 extend along the radial direction of the conical sleeve 32 and are connected to the outer periphery of the conical sleeve 32 in an inclined manner forming an included angle with the horizontal direction, and the inclined surface of the blade 31 connected to the outer periphery of the conical sleeve 32 in the inclined manner can be formed as a stirring part when the material is stirred.

For better stirring of the material, the blades 31 extend away from the conical sleeve 32 in the radial direction of the conical sleeve 32 while being curved toward the downstream in the rotational direction of the stirring impeller 3. When the material is stirred, the material on the stacking angle is firstly driven by the connecting part of the blade 31 abutting against the conical sleeve 32, and then the material moves along with the extending direction of the blade 31 to the blade tip part of the blade 31 far away from the conical sleeve 32 and finally falls into the area of the charging barrel 4 close to the inner wall of the charging barrel 4. When the blades 31 are bent towards the downstream of the rotation direction of the material stirring impeller 3, the materials moving along the extension direction of the blades 31 can be buffered, and the buffered materials fall into the charging barrel 4 under the action of gravity when reaching the tips of the blades 31 instead of flying out along the radial direction of the main shaft 1, so that the risk that the materials are thrown out of the charging barrel 4 by the material stirring impeller 3 is reduced. That is, the feeder of this embodiment is actually a process in which the material poking impeller 3 slowly pokes the material on the stacking angle to the periphery when removing the stacking angle, rather than forcefully throwing the material out.

As shown in fig. 4, another aspect of the present embodiment further provides a material conveying device, which includes the above-mentioned feeder and a barrel 4, the barrel 4 is used for receiving the material of the feeder, and a material stirring impeller 3 of the feeder extends into the barrel 4. In a preferred version of the embodiment, the kick-off impeller 3, which extends into the barrel 4, is arranged close to the receiving opening of the barrel 4.

Based on the above basic structure, the material-stirring impeller 3 of the feeder of the material conveying device of this embodiment is deep into the material cylinder 4, when the material in the material cylinder 4 is not accumulated, the conical sleeve 32 of the material-stirring impeller 3 falls to the lowest position of the main shaft 1 under the action of gravity, the conical sleeve 32 falling to the lowest position of the main shaft 1 and the conical end 11 form a gap in the axial direction of the main shaft 1, the main shaft 1 does not transmit power to the material-stirring impeller 3, the material-stirring impeller 3 does not rotate, when the material starts to accumulate to the material-stirring impeller 3, the conical sleeve 32 is lifted by the material and pressed onto the conical end 11 of the main shaft 1, at this time, the main shaft 1 transmits power to the conical sleeve 32 through the conical surfaces in close contact with each other, the material-stirring impeller 3 starts stirring, the material-stirring impeller 3 and the main shaft 1 are in the state of pressing fit, separation, pressing fit, and separation, that is, the material-, and continuing to feed the main shaft 1 and the feeder when the charging barrel 4 is about to be filled, continuing to feed the material by the material stirring impeller 3 under the inertia effect until the blades 31 of the material stirring impeller 3 stop rotating from the connecting part close to the conical sleeve 32 to the blade tip part and are blocked by the material in the charging barrel 4, and finishing the whole process of removing the stacking angle and leveling the material.

The other parts in the second embodiment are the same as those in the first embodiment, and are not described herein again.
