Vertical shaft planetary mixer gearbox

Abstract

The present invention relates to a vertical shaft planetary mixer gearbox mainly consisting of three parts, i.e. a reduction motor, (an upper gearbox or simple upper box body A2), and a lower gearbox and containing a splined shaft therein. The reduction motor is externally arranged; the upper gearbox revolves; the lower gearbox rotates. In implementation, after a connecting disc of an output shaft of the upper gearbox is connected to a middle housing of an upper cover of the lower gearbox by means of bolts, the reduction motor is mounted in reduction motor mounting holes around the perimeter of a top cover of the upper gearbox. The end of the splined shaft provided with spline teeth passes through a central through hole provided with spline teeth in a central stationary main gear shaft of the lower gearbox via a central through hole of the output shaft in the upper gearbox. After a fixing disc at the upper end of the splined shaft is bolted to the middle housing of the upper cover of the upper gearbox, the splined shaft deadlocks a stationary main gear. Thus, after the reduction motor is started, the output shaft of the upper gearbox rotates so as to also rotate the entire lower gearbox, making revolutions. As the stationary main gear in the lower gearbox is deadlocked immovable by the splined shaft, gears beside the stationary main gear rotate along with the stationary main gear, making rotations. The present invention exhibits a simple structure, a low cost and a low failure rate, and is durable.

Description

Gear box of vertical shaft planetary mixer

[0001] The present application claims priority to the Chinese patent application No. 202410457439.0, 202420787543.1, filed on April 16, 2024, entitled "Gear box of vertical shaft planetary mixer", the whole content of which is incorporated herein by reference. TECHNICAL FIELD

[0002] The present application relates to the technical field of vertical shaft planetary mixers, in particular to a gear box of a vertical shaft planetary mixer. BACKGROUND

[0003] At present, there are rolling barrel type small mixers and horizontal shaft type forced mixers on the market for mixing and stirring equipment such as concrete and dry mortar, wherein the rolling barrel type small mixer can only stir wet mortar and cannot stir dry concrete. The horizontal shaft type forced mixer has the defects of low stirring efficiency, easy entry of wet mortar and cement mortar into the bearing to cause bearing seizure and other faults, uneven stirring, and difficult maintenance.

[0004] The vertical shaft planetary mixer has high efficiency and uniform stirring, but its mixer gear box design is complex, difficult to maintain, and high in cost. The vertical shaft type mixer on the market is almost twice as expensive as the horizontal shaft type forced mixer of the same model, and is difficult to maintain. The revolution, rotation and speed reduction of the gear box of the prior art vertical shaft mixer are arranged in one gear box, which has a complex structure. If a small part is damaged, the entire gear box needs to be disassembled, so the failure rate is high and maintenance is difficult. Moreover, only one power motor can be installed, so the motor power needs to be large. The large power motor cannot be started under load, and if the power is cut off or the electrical appliance fails during stirring, the material in the mixer needs to be manually emptied to start. If the motor is burned and removed for maintenance, it is also difficult. When starting, the stress point is at one position, which can easily damage the gear. Therefore, although the vertical shaft type mixer is good to use, its high price and difficult maintenance limit its development and popularization.

[0005] Therefore, it is urgent to invent a large power vertical shaft planetary mixer gear box with low cost, simple structure, low failure rate and durability and easy maintenance. SUMMARY

The connecting disc (11) is connected to the middle of the upper cover (106) of the lower gear box (B) by bolts. The hollow through hole (25) in the middle of the output shaft (7) is used for installing the spline shaft (9). The upper cover (104) of the upper gear box is provided with a mounting hole (26) for mounting the reduction motor (2). The mounting hole (26) is provided with a toothed bolt hole (58F) beside it for fixing the reduction motor (2).

In this way, part of the large mixer can be assembled with the upper gear box (A), and the small mixer can be assembled with the simple upper box body (A2), which realizes the rational use of resources. If the small mixer is assembled with the upper gear box (A), it is equivalent to killing a pig with a knife and wasting resources.

[0009] The vertical shaft planetary mixer gear box further comprises the spline shaft (9), characterized in that the spline shaft (9) is provided with a fixed disc (10) at the upper end, a bolt hole (27) is arranged around the edge of the fixed disc (10), a spline tooth (41) is arranged at the lower end of the spline shaft (9), a pressure bearing position (108) is further arranged at the outer end of the spline tooth (41), a threaded screw rod (107) is further arranged at the outer end of the pressure bearing position (108), when the spline is installed by the second method in claim 6, the outer end of the spline tooth (41) at the end of the spline shaft is not provided with the pressure bearing position (108) and the screw rod (107), the reduction motor (2), the upper gear box (A) or the simple upper box (A2), the lower gear box (B) and the spline shaft (9) are connected by bolts, after the end connecting disc (11) of the output shaft (7) of the upper gear box and the bolt hole (20a) in the middle of the lower gear box (B) are assembled together by bolts, one end of the spline shaft (9) with the spline tooth (41) passes through the hollow through hole (25) of the output shaft (7) and enters the through hole (19) with the spline tooth in the middle of the fixed main gear shaft (18) in the lower gear box (B), the upper pressure bearing (109) is installed on the pressure bearing position (108), the nut (111) is screwed on the screw rod (107), and the sealing cover is covered, the fixed disc (10) at the upper end of the spline shaft is fixed on the upper cover (104) of the upper gear box (A) by bolts, so that the weight of the lower gear box is on the pressure bearing (109), which is equivalent to that the lower gear box (B) is hung on the upper cover of the upper gear box (A) by the spline shaft (9), the vertical force of the bearing in the upper gear box (A) is not subjected, the vertical force points are all on the pressure bearing (109), the bearing in the upper gear box (A) is only subjected to horizontal force, the service life of the bearings in the upper and lower gear boxes is improved, the reduction motor (2) is installed in the reduction motor (2) mounting hole (26) of the upper gear box (A), the output shaft (7) in the upper gear box (A) is rotated after the reduction motor (2) is started, the whole lower gear box (B) is also rotated to form revolution, the fixed main gear (17) in the middle of the lower gear box (B) is fixed on the upper cover (104) of the upper gear box (A) by the spline shaft (9) to form death, when the whole lower gear box (B) rotates, the fixed main gear (17) in the lower gear box (B), the stirring gear (45) and the transition gear (24) beside it rotate around the fixed main gear (17) to form rotation, the rotation speed of the rotation is adjusted by the size of the fixed main gear (17) in the middle of the lower gear box (B), the traditional design is two to three times faster than the revolution, if the design is according to this speed, the fixed main gear (17) in the middle of the lower gear box (B) is two to three times larger than the stirring gear (45) and the transition gear (24) beside it to achieve the traditional speed, if faster is needed, the fixed main gear (17) in the middle is further increased, through this design,Simple several gears and spline shafts (9) can complete complex working principle, and maintenance is simple and durable. The lower gear box (B) is assembled with the upper gear box (A) as the upper part of the large mixer, the spline (9) is installed by the first method of claim 6, the lower gear box (B) is assembled with the simple upper box (A2) as the upper part of the small mixer, and the spline (9) is installed by the second method of claim 6. Because the small mixer only needs a small power reduction motor (2), the load start can be realized. The traditional large mixer only installs a reduction motor, so the motor power needs to be very large. The defect of the large motor is that it cannot be started under load. The mixer must be able to start under load. (Such as sudden power failure, line failure, etc.) The mixer stops during the mixing process. If it cannot start under load, the mixer will stop suddenly when mixing materials, and the materials in the mixer will be emptied manually before starting. Therefore, in order to solve the defect of not being able to start under load, a transition output gear (6) is arranged in the upper gear box (A), a hole (26) for installing the reduction motor (2) is arranged on the cover (104) of the upper gear box (A), and a plurality of reduction motors (2) can be arranged with the hole (26) for installing the reduction motor (2) and the transition output gear (6).

The large power motor required by the large mixer can be obtained by splicing multiple reduction motors together. Load starting can also be realized. A large mixer without defects can also be produced according to the demand. The largest machine type of the present scheme can realize stirring from 0.1 square to 20 square or more. The small mixer with a power below 30KW can meet the motor power demand of the equipment by installing a motor. In order to save costs, the part of the feature of the upper gear box (A) that is not needed for the small mixer is removed to form (A2). The upper part of the lower gear box (B) as a small mixer can be selectively installed with the simplified upper box (A2) which only installs a reduction motor (2). The load starting can be realized. If the cost is not considered, the small mixer can also be assembled with the upper gear box (A). The transition output gear (6) in the gear box is not stressed at one point when it is started, but as many points as the number of reduction motors (2) installed. Therefore, no matter how large the motor power is, the gear teeth will not be broken. The service life of the gear is improved, and the failure rate is reduced. The large power motor required by the equipment can be obtained by splicing multiple reduction motors (2) together. Each reduction motor can be controlled within 30KW. Load starting can be realized, and the defect of not being able to start under load is solved. The structure of the lower gear box (B) has the advantage that a whole row of wolf tooth rod-shaped stirring knives (65) can be installed.Turn a few circles can quickly and evenly mix the material, really do no dead angle mixing.

[0010] According to one scheme of the application, the front and rear extension of the stationary main gear (17) in the lower gear box (B) increases the stirring gear (45), the stirring gear shaft (45a) and the transition gear (24), the transition gear shaft (24a), the stirring gear shaft (45a) of which extends out of the box body and is connected and installed with the cake (54), and the stirring foot (16) or the wolf tooth shaped stirring knife (65) can be selected and installed according to the needs, so that a group of stirring feet and a group of stirring knives are combined to stir, so that the material is more quickly and evenly stirred. "Any direction beside the stationary main gear (17) can be extended to increase the transition gear (24), the transition gear shaft (24a) and the stirring gear (45), the stirring gear shaft (45a)", the single stirring gear shaft (45a) extends out of the box body as a stirring gear shaft (45a), and the stirring foot (16) or the wolf tooth shaped stirring knife (65) is installed, and the stirring foot (16) or the wolf tooth shaped stirring knife (65) is connected and installed with the connecting cake (54) by bolts. The beneficial effect of installing more wolf tooth shaped stirring knives (65) is that the material can be quickly and evenly stirred, and the stirring efficiency is improved

[0011] According to one scheme of the application, the stationary main gear (17) in the lower gear box (B) increases the stirring gear (45), the stirring gear shaft (45a) and the transition gear (24), the transition gear shaft (24a), the stirring gear shaft (45a) of which extends out of the box body and is connected and installed with the cake (54), and the stirring foot (16) or the wolf tooth shaped stirring knife (65) can be selected and installed according to the needs, so that a group of stirring feet and a group of stirring knives are combined to stir, so that the material is more quickly and evenly stirred. "Any direction beside the stationary main gear (17) can be extended to increase the transition gear (24), the transition gear shaft (24a) and the stirring gear (45), the stirring gear shaft (45a)", the single stirring gear shaft (45a) extends out of the box body as a stirring gear shaft (45a), and the stirring foot (16) or the wolf tooth shaped stirring knife (65) is installed, and the stirring foot (16) or the wolf tooth shaped stirring knife (65) is connected and installed with the connecting cake (54) by bolts. The beneficial effect of installing more wolf tooth shaped stirring knives (65) is that the material can be quickly and evenly stirred, and the stirring efficiency is improved

[0012] According to the second embodiment of the vertical shaft planetary mixer gear box of the present application, the said reduction motor (2), upper gear box (A), lower gear box (B), further comprising a rotation gear box (C), the second embodiment is characterized in that the said independent rotation gear box (C) is basically the same as the upper gear box (A), the difference is that the output shaft (7) is replaced by a solid output shaft (7a), the output shaft (7a) is very long and extends out of the lower box, the end of the output shaft (7a) is provided with a spline tooth (41), and the output shaft (7a) is set to a length that can be inserted into the fixed main gear shaft (18) with a spline tooth hole (19) inside the lower gear box (B) during implementation. The characteristics and claims of the second embodiment of the lower gear box B are the same as those of the first embodiment. The rotation of the gear in the gear box is different. After the independent rotation gear box (C) is set, the fixed main gear (17) in the middle of the lower gear box (B) becomes a driving gear (17), so that the driving gear (17) does not need to adjust the speed of the stirring shaft (45a), and the actual required speed is completed by the reduction motor (2) on the rotation gear box (C), so the diameter of the driving gear (17) can remain unchanged or be the same as the gear next to it. The transition gear (24) and the stirring gear (45) next to it also remain unchanged. The gear next to the driving gear (17) becomes a passive gear, so the revolution speed is determined by the reduction motor (2) on the upper gear box (A), and the rotation speed is determined by the reduction motor (2) on the rotation gear box (C). The revolution and rotation speeds can be set according to the speed of the respective reduction motor (2), and the number of revolutions can be set. If the required rotation speed reaches the speed of the motor, the reduction motor (2) is not installed, and the motor is installed directly. After setting the rotation gear box (C), this scheme does not need to set the spline shaft (9). The mounting hole (26) of the reduction motor (2) on the rotation gear box (C) is added to the mounting hole (26) of the reduction motor on the gear box (A), so that more reduction motors (2) can be installed, and large-scale mixers can be produced according to needs. When this scheme is implemented as a small mixer, the rotation gear box (C) is not set, and the reduction motor (2) or motor is installed directly. However, the output shaft (4) of the reduction motor (2) is also as long as the output shaft (7a) of the rotation gear box (C), and the end is also provided with a spline tooth (41). After the end of the connecting disc (11) of the said upper gear box (A) is connected to the bolt hole (20a) in the middle of the upper cover (106) of the lower gear box (B) with a bolt, one end of the spline tooth (41) at the end of the output shaft (7a) of the rotation gear box (C) is inserted into the fixed main gear shaft (18) inside the lower gear box (B) through the middle hollow hole (25) of the output shaft (7) of the upper gear box (A), and the spline tooth hole (19) in the middle is inserted. The rotation gear box (C) is fixed to the upper cover (104) of the upper gear box (A) with a bolt.And the reduction motor (2) is installed in the reduction motor mounting hole (26) of the upper gear box (A) and the rotation gear box (C), and the wolf tooth shaped stirring knife (65) or stirring foot (16) is installed on the cake (54) connected to the end of the stirring gear shaft (45a), after installation, the reduction motor (2) of the upper gear box (A) starts to rotate the output shaft (7), which also rotates the entire lower gear box (B) to form revolution, and the reduction motor of the rotation gear box (C) starts to rotate all the gears in the lower gear box (B) to form rotation, so the rotation speed of revolution and rotation is determined by the reduction motor (2) on the gear box, so the rotation speed of revolution and rotation can be set according to the need, and the number of revolutions is set, which has no limitation. The power of the rotation of the present scheme is within 30kw motor, which can drive the machine type without setting the rotation gear box (C) directly installing the reduction motor (2), the output shaft (4) of the reduction motor (2) is also set as the output shaft (7a) of the rotation gear box (C). The advantage of the present scheme is that the rotation speed of revolution and rotation can be from 5 to 2800 rpm or even faster. Generally, revolution is very slow, and rotation has fast demand. The existing technology cannot be fast because if the rotation is fast, the revolution must also be set fast, but the revolution cannot be fast. At present, the fastest rotation in the world can only be designed to 700 rpm, but only one or two stirring shafts can achieve fast speed. It cannot achieve fast speed for all stirring shafts in the mixer barrel. Moreover, it is also impossible to install a whole row of stirring knives. The present invention can install a whole row of stirring knives, and all the stirring knives connected by the stirring gear shaft (45a) can achieve the required fast speed. The rotation speed of revolution and rotation has no limit in the present scheme, and the required rotation speed can be set according to the demand. When the required rotation speed reaches the rotation speed of the motor, the reduction motor (2) is not installed on the gear box, and the motor is directly installed. Moreover, after installing the rotation gear box (C), the reduction motor (2) mounting hole (26) of the rotation gear box (C) and the reduction motor (2) mounting hole (26) on the gear box (A) can install more reduction motors (2), so that larger mixers can be produced. At present, the largest mixer in the world can only reach 6 square meters, but the present scheme can be 0.1 to 20 square meters or more. If large mixers are produced, the gears in the upper gear box (A), the lower gear box (B) and the rotation gear box (C) can be thickened in proportion, and the modulus of the gear teeth can be increased to be thick, so that large mixers can be produced. Through this design, the equipment is more durable, the failure rate is low, the maintenance is simple, and the load start can be realized. When the rotation speed of the present scheme is set to be fast, the stirring shaft (45a) can be connected to the wolf tooth shaped stirring knife (65).

[0013] According to a third embodiment of the vertical shaft planetary mixer of the present application, a set of stirring feet (16a) is composed of a reduction motor (2), an upper gear box (A) or a simple upper box (A2), the upper gear box (A) is a combined structure with multiple reduction motors or a simplified structure of the simple upper box (A2) with a single reduction motor, both of which can realize negative starting according to the power requirement of the equipment, the upper part of the set of stirring feet (16a) can be optionally equipped with the upper gear box (A) when implemented as a large-scale mixer, and the upper part of the set of stirring feet (16a) can be optionally equipped with the simple upper box (A2) as required in claim 2 when implemented as a small or medium-sized mixer, the present application does not set the lower gear box (B) and the spline shaft (9), but sets the set of stirring feet (16a), the set of stirring feet (16a) is composed of multiple single stirring feet (16E) and a thick steel plate (81) containing a round steel pipe (100), the set of stirring feet (16a) is characterized in that a thick steel plate (81) is arranged above the middle of the set of stirring feet (16a), a round bolt hole (20a) is arranged in the middle, the bolt hole (20a) is matched with the bolt hole (20) of the output shaft (7) of the upper gear box (A) or the simple upper box (A2) and the end connecting disc (11), multiple single stirring feet (16E) are welded around the thick steel plate (81) to assemble the set of stirring feet (16a), a round steel pipe (100) is arranged below the thick steel plate (81) in the middle of the set of stirring feet (16a), a bearing hole (115) is arranged above the middle of the round steel pipe (100) for installing a bearing (114), a bearing cover (116) with a hole is further arranged above the bearing, a stabilizing shaft (112) is arranged below the middle of the thick steel plate (81), the end of the shaft of the stabilizing shaft (112) is provided with a bearing position (113) for installing a bearing (114), the end bearing position (113) of the stabilizing shaft (112) below the middle of the thick steel plate (81) is just fitted into the bearing (114) above the middle of the round steel pipe (100), which makes the stirring feet (16a) more stable and increases the service life of the bearings of the upper gear box (A).

[0014] The round steel pipe (100) is installed in the middle of the barrel bottom of the mixer barrel and under the thick steel plate (81) in the middle of the whole set of stirring feet (16a) in a welded manner. The installed round steel pipe (100) is relatively large. The diameter of the round steel pipe (100) cannot be too large or too small. The diameter is determined by the uniform stirring of the material in the middle and the material on the outside during stirring. After the middle is provided with the round steel pipe (100), the middle is blocked by the round steel pipe (100) and there is no material in the middle. Because the stirring radius in the middle is very small, it is difficult to stir the material in the middle to the outside, resulting in uneven stirring of the material. After the middle is provided with the round steel pipe (100), the middle is blocked by the round steel pipe (100) and there is no material in the middle. The stirring radius of the stirring foot (16E) is also increased. In this way, the material can be stirred uniformly. During stirring, there is no uneven stirring of the material in the middle and on the outside. The arrangement of the single stirring foot (16E) is characterized in that the single stirring foot (16E) on the middle thick steel plate (81) is lengthened transversely by a thick steel pipe. The thick steel pipe is directly welded or connected in a detachable manner at the turning point of the thick steel pipe after lengthening the single foot (16E) vertically downward. If the thick steel pipe is connected in a detachable manner, the feature is that a square connecting plate (120) is arranged at the outer end of the thick steel pipe. A bolt hole (121) is arranged on the square connecting plate (120). A square connecting plate (120a) is also arranged at the upper end of the vertically downward stirring foot (16E). A bolt hole (121a) is arranged on the square connecting plate (120a). The bolt hole (121) is matched with the bolt hole (121a). The square connecting plate (120) and the square connecting plate (120a) are connected by bolts. A wear-resistant steel foot plate (6S) is arranged at the lower end of the vertically downward stirring foot (16E). The length of the first transversely lengthened thick steel pipe is such that the wear-resistant steel foot plate (16S) at the lower end can scrape the edge of the mixer barrel. The length of the second transversely lengthened thick steel pipe is shorter than that of the first thick steel pipe. The wear-resistant steel foot plate (16S) at the lower end can just scrape the edge of the first wear-resistant steel foot plate (16S) on the inner side of the outer wear-resistant steel foot plate (16S). The wear-resistant steel foot plate (16S) at the lower end of the third stirring foot (16E) also exceeds the inner side of the wear-resistant steel foot plate (16S) of the second wear-resistant steel foot plate (16S) by a little. The arrangement is continued inwardly. If no round steel pipe (100) is arranged in the middle, the most inward stirring foot (16E) is arranged to exceed the center point. The whole set of stirring feet (16a) can scrape the inside of the mixer barrel without dead angles. The single stirring foot (16E) near the outer edge of the mixer barrel has a wear-resistant steel foot plate (16S) at the bottom. The front of the wear-resistant steel foot plate (16S) is outwardly inclined. The rear is inclined to the center of the mixer barrel.

The front of the wear-resistant steel foot plate (16S) at the bottom of the single stirring foot (16E) near the center is inwardly inclined.The rear is outwardly inclined, and the wear-resistant steel plates (16S) on the front and rear edges form an outward eight-shaped structure. The wear-resistant steel plates (16S) on the outer edge stir the material in the middle to the outside, and the wear-resistant steel plates (16S) on the inner edge stir the material in the middle to the outside. Through repeated stirring from the inside to the outside, the material can be quickly and uniformly stirred. The front and rear of the wear-resistant steel plates (16S) are defined as the clockwise rotation direction when viewed from the top of the entire set of stirring legs (16a). The beneficial effect of the outward eight-shaped installation of the wear-resistant steel plates (16S) is that the material on the inner edge of the stirring barrel is more easily stirred to the middle, and the material in the middle is more easily stirred to the outside by the outward eight-shaped wear-resistant steel plates. Through repeated stirring from the inside to the outside, the material is quickly and uniformly stirred, and the stirring efficiency is improved. The number of single stirring legs (16E) is determined according to the size of the machine.

The upper and lower gear boxes are simple in structure and do not need to have the function of speed reduction, only as a transmission function, the precise speed is completed by the external reduction motor 2, so the gear teeth can be set to very thick large modulus teeth according to the needs, as a super large mixer, there will be no tooth collapse phenomenon, wear-resistant, durable and low failure rate

[0054] The advantages of the present application are that: the upper gear box upper cover covers a circle above the edge of the transition output gear 6 in the box, and the installation hole 26 for installing the speed reducer motor 2 can be arranged corresponding to the transition output gear 6 in the box, the input gear 5 is installed on the output shaft 4 of the speed reducer motor 2, so that multiple speed reducer motors can be installed, and the motor power does not need to be very large, the external speed reducer motor 2 can also be matched with a small power motor, through this design, the speed reducer is durable and not easy to break, and the gears in the upper and lower gear boxes can be set to thick and thick gears with large module teeth, which are also stressed and wear-resistant, after setting multiple speed reducer motors 2, the transition output gear 6 of the upper gear box A is not stressed at one point when starting, but stressed at multiple points according to the number of speed reducer motors 2 installed, and the gears are also not easy to wear, which greatly increases the service life of the gears and the speed reducer, through this ingenious design of the gear box and the speed reducer, they are also durable and not easy to break, and the failure rate is also reduced, the existing technology of the vertical shaft planetary mixer in the world can only reach the limit of stirring 6 square meters, but the mixer of the present application can stir 0.1 cubic meters to 20 cubic meters, and larger mixers can also be produced according to needs, because the upper and lower gear boxes of the present application have simple structure and do not need to have a speed reduction function, only as a transmission function, the required accurate speed is completed by the external speed reducer motor 2, therefore, the gear teeth can be set to very thick gears with large module teeth according to needs, so that the gear teeth will not be broken, the wear failure rate is low, and the maintenance is simple, because the upper and lower gear boxes of the present application are composed of large module gears, if a large mixer is needed, only the proportion of the upper and lower gear boxes needs to be increased, the thickness of the gears and the gear teeth module in the gear boxes are increased, and more speed reducer motors can be installed after the length of the outer edge of the transition output gear 6 is increased, which is very simple and not easy to break, and the failure rate is low.

The bolt holes (20a) are connected to the output shaft of the upper gear box (A1). (7) The bolt holes (20) of the end connecting plate (11) match each other". The arrangement characteristics of the whole set of stirring feet (16a) are the same as those of claim 8, except that fewer single stirring feet (16E) are installed in the whole set of stirring feet (16a), and a part of space is reserved in the middle and lower part for installing the mace-shaped stirring blade (65). The reduction motor (2), the reduction motor (2a), the upper gear box (A1), the whole set of stirring feet (16a), and the mace-shaped stirring blade (65) are connected and installed with bolts. Different implementation schemes of this scheme can also achieve the functional effect of claim 1.

12. A fifth embodiment of a vertical shaft planetary mixer gearbox is composed of a reduction motor (2), an upper gearbox (A) or a simple upper gearbox (A2), a mixer foot and gearbox combined lower gearbox (B2) which includes a spline shaft (9), "the upper gearbox (A) is a combined structure with multiple reduction motors or a simple upper gearbox (A2) with a single reduction motor, both of which can achieve negative starting according to the power requirements of the equipment motor", the mixer foot and gearbox combined lower gearbox (B2) can be equipped with an upper gearbox (A) on the upper part when implemented as a large mixer, "the spline shaft (9) is installed according to the first installation method of claim 6", the mixer foot and gearbox combined lower gearbox (B2) can be equipped with a simple upper gearbox (A2) on the upper part when implemented as a small or medium-sized mixer, "the spline shaft (9) is installed according to the second installation method of claim 6 after the upper part is equipped with a simple upper gearbox (A2)", and "the spline shaft (9) does not have a pressure bearing position (108) and a screw rod (107) at the outer end of the spline teeth (41) at one end when the upper part is equipped with a simple upper gearbox (A2)", "the mixer foot and gearbox combined lower gearbox (B2) is composed of a gearbox and multiple individual mixer feet (16E)", "the bearing hole (34) in the middle of the upper cover plate (106) also has a bolt hole (20a) with teeth next to it, which matches the bolt hole (20) on the output shaft end connecting disc (11) of the upper gearbox (A) or simple upper gearbox (A2)", "the upper cover plate (106) is wider and thicker than the gearbox, and the wider edge of the upper cover plate (106) is used to weld a complete set of mixer feet (16a)", "the mixer foot and gearbox combined lower gearbox (B2) is equipped with two gears and gear shafts, one is a stationary main gear (17) and a stationary main gear shaft (18), the other is a stirring gear (45) and a stirring gear shaft (45a)", "the features of the two gears are the same as those of the stationary main gear (17) and the stationary main gear shaft (18) of the lower gearbox (B) and the stirring gear (45) and the stirring gear shaft (45a) next to it", "the difference is that there are more gears installed next to the stationary main gear (17) in the gearbox (B), while there are fewer gears installed next to the stationary main gear (17) in the mixer foot and gearbox combined lower gearbox (B2)", "the stirring gear shaft (45a) extends out of the gearbox and is equipped with a connecting disc (54) and a wolf tooth shaped stirring knife (65) at the end", "the number of stirring gears (45) and stirring gear shafts (45a) next to the stationary main gear (17) can be determined according to the requirements", "the features of the complete set of mixer feet (16a) are the same as the arrangement of the individual mixer feet (16E) in claim 11, and the number of individual mixer feet (16E) is enough to scrape the mixer barrel to no dead angle",The difference is that the center of the stirring foot (16a) is provided with a self-rotating gear box (B2), and the wolf tooth-shaped stirring knife (65) is not at the center but beside the center. The distance from the center point depends on the required rotating speed of the stirring shaft (45a). The faster the rotating speed of the stirring shaft (45a), the larger the fixed main gear (17) needs to be, and the farther the stirring shaft (45a) is from the center point. The wolf tooth-shaped stirring knife (65) is not at the center, but the length of the blade installed on the wolf tooth-shaped stirring knife (65) exceeds the center point. The stirring area of the wolf tooth-shaped stirring knife (65) rotating one circle is wider than the stirring area at the center point. The reduction motor (2), the upper gear box (A) or the simple upper box (A2), the stirring foot and the gear box mixed lower gear box (B2), and the spline shaft (9) are connected and assembled by bolts. The two different embodiments of the present scheme can also achieve the functional effects of claim 1.

13. "According to claims 8, 11 and 12, the front of the wear-resistant steel foot plate (16S) at the bottom of the single stirring foot (16E) near the outside of the mixer barrel is installed with its front facing outward and its rear facing toward the center of the mixer barrel in an inclined manner. "The wear-resistant steel foot plate (16S) at the bottom of the innermost single stirring foot (16E) near the center is installed in the opposite direction to the wear-resistant steel foot plates (16S) outside. The wear-resistant steel foot plate (16S) at the bottom of the innermost single stirring foot (16E) near the middle is installed with its front facing inward and its rear facing outward in an inclined manner. In this way, the wear-resistant steel foot plates (16S) inside and outside form an outward-facing "X" shape." The front and rear of the wear-resistant steel foot plate (16S) are based on the clockwise rotation direction of the entire set of stirring feet (16a) when viewed from above.
