Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, technical solutions between various embodiments may be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination should not be considered to exist, and is not within the protection scope of the present invention.
Referring to fig. 2, the present invention discloses a material separating assembly 10b, which is mainly applied to a concrete material separating machine. The driving device of the concrete distributor drives the distributing shaft 100 of the distributing assembly 10b to rotate, and the distributing plate 220 on the distributing shaft 100 rotates along with the rotation of the distributing shaft 100, so as to convey the materials to be distributed according to a preset mode. The material distributing assembly 10b can shorten the production period of the material distributing assembly 10b and improve the production efficiency.
Referring to fig. 2, in an embodiment of the material distributing assembly 10b of the present invention, the material distributing assembly 10b includes a material distributing shaft 100 and a material distributing impeller 200; the middle of the distributing impeller 200 is penetrated with a shaft hole 211 extending along the length direction thereof, and the distributing impeller 200 is sleeved on the periphery of the distributing shaft 100 through the shaft hole 211 (the shaft hole 211 can refer to fig. 4).
Specifically, the distributing impeller 200 has a base 210 at a middle region thereof, and a plurality of distributing plates 220 provided on the base 210 (the base 210 and the distributing plates 220 may refer to fig. 5); wherein, the base 210 is provided with a shaft hole 211 for the material-distributing shaft 100 to pass through; the material distributing plates 220 extend along the length direction of the material distributing impeller 200, and a material groove 230 is formed between any two adjacent material distributing plates 220. When the material distributing assembly 10b works, the driving device drives the material distributing shaft 100 to rotate, and the material distributing shaft 100 drives the material distributing impeller 200 to synchronously rotate; in the process that the material distribution impeller 200 rotates along with the material distribution shaft 100, the material groove 230 turns up and down along with the material distribution impeller, and when the material groove 230 turns to the upper side, the material falls into the material groove 230 from the upper side of the material distribution impeller 200; when the material groove 230 is turned to the lower side, the material falls from the material groove 230 to the preset conveying position below.
As for the fixing manner of the distributing shaft 100 and the distributing impeller 200, threads may be provided on the shaft holes 211 of the distributing shaft 100 and the distributing impeller 200 to connect the two by the threads. Alternatively, positioning nuts 300 may be mounted on both ends of the feed shaft 100, and the feed impeller 200 may be clamped together by the two positioning nuts 300 to prevent the feed impeller 200 from moving. As will be described in more detail hereinafter.
According to the technical scheme, the distributing impeller 200 is arranged on the distributing shaft 100, the shaft hole 211 extending along the length direction of the distributing impeller 200 is arranged in the middle of the distributing impeller 200 in a penetrating mode, and the distributing impeller 200 is sleeved on the periphery of the distributing shaft 100 through the shaft hole 211, so that the distributing impeller 200 can be integrally formed in a die-casting mode when the distributing impeller 200 is produced, and further batch production is achieved. The formed material distributing impeller 200 can be directly sleeved on the material distributing shaft 100. Therefore, compared with the prior art that the plate-shaped material distributing plate 220 is directly welded on the material distributing shaft 100, the material distributing impeller 200 is adopted to replace the material distributing plate 220, the material distributing impeller 200 is sleeved on the periphery of the material distributing shaft 100 through the shaft hole 211, operations such as cutting, welding and machining are not needed to be carried out one by one, the production process is simple, the production period is effectively shortened, and the production efficiency is further improved.
In addition, the distributing impeller 200 can be integrally die-cast and molded, so that a welding gap 400 (as shown in fig. 1) cannot occur in the material groove 230, on one hand, the material groove 230 can be smooth, meanwhile, no dead angle is formed between the distributing shaft 100 and the distributing plate 220, the viscous force of the material groove 230 is small, the material groove is not easy to stick concrete, the concrete can be ensured to smoothly enter or separate from the material groove 230, and the material accumulation in the material groove 230 is avoided; on the other hand, the material distributing plate 220 has strong strength and cannot easily fall off from the material distributing impeller 200, thereby effectively improving the use effect and prolonging the service life of the material distributing assembly 10 b.
Referring to fig. 3 to 5, in the present embodiment, the number of the distributing impellers 200 may be one or more. If the number of the distributing impellers 200 is one, the length of the distributing impeller 200 needs to be properly extended to increase the capacity of the material tank 230 in order to ensure that one distributing impeller 200 can simultaneously convey more materials. Only in consideration of the fact that the difficulty of the die casting process is correspondingly increased when a longer distribution impeller 200 is die cast, the distribution impeller 200 can be cast in sections to avoid the situation. Therefore, it is preferable that the distributing impeller 200 includes a plurality of sub-impellers 200a, and the sub-impellers 200a are sequentially joined along the length direction of the distributing shaft 100.
Specifically, the sub-impellers 200a are sequentially spliced along the length direction of the material separating shaft 100, and the material grooves 230 on any two adjacent sub-impellers 200a are respectively connected in a pair to form a larger material groove 230. The sub-impellers 200a are seamlessly spliced, the splicing position 500 between any two adjacent distribution impellers 200 is tight, and the splicing position 500 is consistent with the moving direction of the material, so that the viscous force is small, and the adhesion with the material is not easy to occur.
The specific number of the sub-impellers 200a is not specifically limited, and may be 1 to 10, for example, 2, 3, 4, 5, 6, or 8, and the like, and the specific number should be selected according to the length of the material separating shaft 100 in practical application. For example, for a medium-sized and small-sized concrete distributor, the use amount (1-5) of the sub-impellers 200a can be reduced appropriately; for a large-sized concrete distributor, the use amount (5-10) of the sub-impellers 200a can be properly increased, so that the distributing assembly 10b can be suitable for concrete distributors of different sizes, and the applicability of the distributing assembly 10b is greatly improved.
Therefore, the length of a single sub-impeller 200a can be properly reduced by increasing the number of the sub-impellers 200a, and when the material distribution impeller 200 is manufactured, the plurality of sub-impellers 200a can be respectively forged, so that the mass production is realized, and the forging difficulty is low; during assembly, the distribution impellers 200 are sequentially spliced and mounted on the distribution shaft 100, assembly operation is simple, and production efficiency is effectively improved.
Referring to fig. 4 and fig. 6, in the embodiment, considering that when the material distributing assembly 10b operates, the material falls onto the distributing impeller 200 from top to bottom, and the magnitude of the acting force applied by the material on the two adjacent sub-impellers 200a is different, the two sub-impellers 200a may be misaligned, so that the distributing efficiency of the distributing impeller 200 is reduced. Therefore, in order to avoid the above situation, the positioning column 24a is convexly disposed on the end surface of the sub-impeller 200a, the positioning hole 24b is concavely disposed on the end surface of the adjacent sub-impeller 200a, and the positioning hole 24b is inserted into the positioning column 24 a. When any two adjacent sub-impellers 200a are connected into a whole through the positioning column 24a and the positioning hole 24b, the connection stability is high similar to the process of "nailing" the two sub-impellers together, so that the two sub-impellers are subjected to the acting force exerted by the material and are difficult to be dislocated.
Specifically, one end surface of the first-positioned sub-impeller 200a is provided with a positioning column 24 a; one end surface of the cotyledon wheel 200a positioned at the last position is provided with a positioning hole 24 b; the remaining sub-impellers 200a serve as intermediate sub-impellers 200a, and one end surface thereof is provided with a positioning hole 24b, and the other end surface thereof is provided with a positioning column 24 a. During assembly, the middle sub-impeller 200a is sequentially spliced between the first sub-impeller 200a and the last sub-impeller 200a, so that the plurality of sub-impellers 200a are assembled into a whole, the connection stability is higher, the strength is higher, and dislocation is not easy to occur.
Referring to fig. 4 and 7, in another embodiment, the difference from the above embodiment is that, considering that a splicing gap may be formed between two adjacent sub-impellers 200a, when the material falls onto the distributing impeller 200, slurry in the material may penetrate into the slot in the splicing position 500, and the slurry is continuously accumulated and solidified, so that the two sub-impellers 200a are fixed together, and the sub-impellers 200a are difficult to disassemble. Therefore, to avoid this, an annular sealing rib 25a is protruded on the end face of the sub-impeller 200a, and the annular sealing rib 25a is surrounded along the periphery of the end face of the sub-impeller 200 a; a sealing groove 25b is concavely arranged on the end surface of the other sub impeller 200a adjacent to the sub impeller 200a, and the sealing groove 25b is inserted with the annular sealing rib 25 a.
As for the specific shape of the annular seal rib 25a, there is no limitation. The annular sealing rib 25a may be disposed in a regular circular shape, a square annular shape, or an irregular annular shape. The closer the annular seal rib 25a is to the periphery of the end face of the sub-impeller 200a, the smaller the depth of the gap that can be formed at the joint position 500 between the two sub-impellers 200a, and the smaller the amount of slurry that can penetrate, and therefore, the annular seal rib 25a is preferably surrounded by the periphery of the end face.
The two adjacent sub-impellers 200a are inserted and connected through the annular sealing rib 25a and the sealing groove 25b, and the annular sealing rib 25a and the sealing groove 25b can play a role in sealing and also can play a role in positioning (such as the positioning role of the positioning column 24a and the positioning hole 24 b), so that the plurality of sub-impellers 200a are assembled into a whole, the connection stability is higher, the strength is higher, and the dislocation is not easy to occur.
Based on the above embodiment, the distributing impeller 200 is further provided with the lightening holes 260 extending along the length direction, and the lightening holes 260 can reduce the material consumed by the distributing impeller 200, thereby reducing the weight of the distributing impeller 200 and reducing the material consumption cost. It should be noted that if the aforementioned positioning hole 24b is provided on the distributing impeller 200, the positioning hole 24b should be provided at a different position from the lightening hole 260 so as to avoid the lightening hole 260.
Referring to fig. 3 and 4, in the present embodiment, in order to facilitate the installation of the distributing impeller 200, the distributing shaft 100 has an installation section 110 for installing the distributing impeller 200, and a cross section of the installation section 110 taken by a plane perpendicular to the axial direction of the distributing shaft 100 may be circular, and correspondingly, a cross section of the shaft hole 211 taken by a plane perpendicular to the axial direction thereof is also circular to fit the shaft hole 211 and the installation section 110. However, in order to avoid the relative rotation between the distributing impeller and the mounting section, it is preferable that the mounting section 110 has a polygonal cross section taken along a plane perpendicular to the axial direction of the distributing shaft 100; accordingly, the shaft hole 211 is provided in a polygonal shape in a cross section taken by a plane perpendicular to the axial direction thereof, so that the shaft hole 211 and the mounting section 110 are fitted.
For the convenience of explanation, a cross section of the mounting segment 110 perpendicular to the axial direction of the material separating axis 100 (the "cross section" is a virtual cross section and is not shown) is defined as S1，S1Any polygon that can be a triangle, a quadrangle, a pentagon, a hexagon, a heptagon, or an octagon is preferable here, and the polygon is a hexagon. On the one hand hexagonal shaft hole211 is well formed and easy to manufacture; and on the other hand, the hexagon has better symmetry and stability.
It is worth mentioning that S1It may be a regular polygon or an irregular polygon. Wherein, for a regular polygon, the center of gravity on the mounting segment 110 is located at S1The geometric center of the mounting section 110 has substantially equivalent torsion moments at all circumferential points of the mounting section 110 in the rotating process of the material distributing shaft 100, and the stress is relatively uniform. For a shaped polygon, the center of gravity on the mounting segment 110 is offset by S1So that the mounting segment 110 can rotate from top to bottom under the action of its partial gravity during the rotation of the distributing shaft 100, thereby rapidly conveying the material to the predetermined conveying position.
Referring to fig. 3 and 4, in the present embodiment, the distributing shaft 100 further has bearing mounting ends 130 at two ends of the mounting section 110, wherein one of the bearing mounting ends 130 is rotatably mounted to the concrete distributor; the other bearing mounting end 130 is adapted to be coupled to a drive means for driving rotation by the drive means. In order to make the bearing mounting end 130 and the mounting section 110 have similar or same torsion moment, it is preferable that the cross section of the bearing mounting end 130 perpendicular to the axial direction of the material separating shaft 100 is polygonal and is similar to S1Is arranged in a profiling way.
Referring to fig. 3 and 4, according to the above embodiment, in order to prevent the separation impeller 200 from being detached from the mounting section 110, preferably, the bearing mounting end 130 is connected to the mounting section 110 through a positioning threaded section 120, an outer diameter of the positioning threaded section 120 is larger than an outer diameter of the bearing mounting end 130, and the positioning threaded section 120 is used for mounting the positioning nut 300. During assembly, the distributing impeller 200 is sleeved to the mounting section 110, the positioning nuts 300 are mounted on the two positioning thread sections 120, and the distributing impellers 200 are pressed tightly through the two positioning nuts 300, so that the distributing impellers 200 are tightly spliced, the distributing impellers 200 are difficult to misplace, and are difficult to separate from the mounting section 110.
Referring to fig. 8, according to any of the above embodiments, for a single sub-impeller 200a, the sub-impeller 200a has a plurality of material distributing plates 220, and the thickness of the material distributing plates 220 is gradually decreased from inside to outside along the radial direction of the sub-impeller 200 a. That is, the thickness of the root of the material distributing plate 220 is larger, so that the strength of the material distributing plate 220 is larger and more stable; the thickness of the top of the material distributing plate 220 is small and sharp, when the materials fall onto the sub-impeller 200a from top to bottom, the materials impact the top of the material distributing plate 220 and are separated into different material grooves 230 by the material distributing plate 220, and the material distributing efficiency is effectively improved.
Referring to fig. 8, it is considered that the material groove 230 is formed between two adjacent sub-impellers 200a, and the side plate surfaces of the two material distributing plates 220 form a first side groove wall 231 and a second side groove wall 232 of the material groove 230, respectively. If any two adjacent sub-impellers 200a are spaced and completely separated, the section of the material groove 230, which is cut by a plane perpendicular to the material distribution shaft 100, is trapezoidal, and obviously, the bottom of the trapezoidal material groove 230 has at least two corner positions, which are narrow and easy to stack materials. Therefore, to avoid this, it is preferable that the bottom end of the side plate surface of any one of the material dividing plates 220 is smoothly connected to the bottom end of the side plate surface of another material dividing plate 220 adjacent to the material dividing plate 220, that is, the first side groove wall 231 and the second side groove wall 232 of the material groove 230 are smoothly connected, so as to avoid forming a corner at the bottom of the material groove 230, reduce the viscous force at the bottom of the material groove 230, and prevent the material from being accumulated.
Referring to fig. 8 and 9, further, the movement path of the material can be improved to prevent the material from being stacked. In the theory of physical motion, the arc motion track is the optimal path of the object falling motion. Therefore, in the present embodiment, the groove bottom of the material groove 230 is formed in an arc shape in a cross section taken by a plane perpendicular to the axial direction of the material distributing shaft 100. When the material falls into the material groove 230 from top to bottom, the material groove 230 turns over along with the rotation of the distributing impeller 200, and the material follows the arc-shaped track of the material groove 230 under the centrifugal force (e.g. arc line P in fig. 9)1P2) And the material slides out of the material groove 230 downwards, so that the friction resistance between the material and the wall surface of the material groove 230 is small, and the obtained falling speed is high.
Referring to fig. 8 and 9, however, for different arc-shaped motion tracks, the falling speed of the material is obtainedDifferent. If the maximum falling speed of the material chute 230 is required, the arc-shaped motion trajectory is the curve of the highest falling speed of the object or is close to the curve of the highest falling speed of the object. For convenience of illustration, the distance from the bottom of the material groove 230 to the center of the shaft hole 211 is defined as D1The distance from the top end of the material distributing plate 220 to the center of the shaft hole 211 is D2(the center of the shaft hole 211, P, is shown as O in FIG. 90Shown is the bottom of the material tank 230, P1And P2Respectively, the top ends of two adjacent material-separating plates 220). After the test, when D1/D2∈[0.5，0.8]In the process, the arc-shaped motion track of the material groove 230 is close to the steepest falling curve of the object, and compared with the blanking speed of the conventional material distributing assembly 10a, the blanking speed of the material distributing assembly 10b of the invention can be increased by more than 5%. As for D1/D2The actual ratio may be 0.5, 0.55, 0.6, 0.65, 0.7, 0.75, 0.8, etc.
The concrete distributor comprises a rack and a distributing component 10b installed on the rack, the concrete structure of the distributing component 10b refers to the above embodiments, and the concrete distributor adopts all the technical schemes of all the embodiments, so that the concrete distributor at least has all the beneficial effects brought by the technical schemes of the embodiments, and further description is omitted. Wherein, a material distributing hopper is arranged on the frame, and the material distributing component 10b is positioned above the material distributing hopper. Preferably, the distribution impeller 200 extends at least partially into the distribution hopper.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
