[0010] Furthermore, the stirring blade also includes an elastic plate, which is disposed on the front side of the blade and located at the end of the blade away from the stirring axis. The elastic plate is perpendicular to the blade and protrudes from the blade in the extending direction of the blade.

[0011] Furthermore, the stirring blade also includes a reinforcing plate, which is disposed on the rear side of the blade and located at the end of the blade away from the stirring axis. The reinforcing plate is perpendicular to the blade and protrudes from the blade in the extending direction of the blade. The elastic plate protrudes from the reinforcing plate in the extending direction of the blade. And / or, the cross-section of the elastic plate in the radial direction of the stirring axis is an arc-shaped structure, and the middle part of the elastic plate protrudes rearward.

[0012] Furthermore, both the rear and front edges of the blade are arc-shaped, with the middle of the rear edge protruding backward and the middle of the front edge concave backward; and / or, the front end of the tumbling protrusion is flush with the front edge of the blade.

[0013] Furthermore, an arc-shaped base is provided at the end of the blade facing the stirring shaft, and the arc-shaped base is attached to the outer wall of the stirring shaft and detachably connected to the stirring shaft.

[0014] Furthermore, the axial spacing between two adjacent stirring blades on the stirring shaft is between 15cm and 25cm; and / or, the included angle between two adjacent stirring blades on the circumferential direction of the stirring shaft is between 25° and 35°.

[0015] Furthermore, the stirring shaft includes at least two stirring sub-shafts that are detachably connected in its axial direction.

[0016] Furthermore, the ratio of the length of the mixing sub-shaft to the length of the mixing shaft is between 20% and 30%; and / or, the mixing shaft also includes a flexible coupling, through which two adjacent mixing sub-shafts are connected.

[0017] Furthermore, the mixing shaft is a hollow shaft, and the ratio of the outer diameter of the mixing shaft to its length is between 5% and 10%.

[0018] Furthermore, the stirring shaft also includes a split-shaft detection component, with the radiation emitting end and receiving end of the split-shaft detection component respectively disposed at both ends of the stirring split-shaft and located inside the hollow cavity of the stirring split-shaft.

[0019] Furthermore, the frame includes a base and a beam disposed on the base. The beam extends axially along the mixing shaft. The beam includes at least two sub-beams corresponding to at least two mixing sub-shafts. The at least two sub-beams are detachably connected axially along the mixing shaft.

Since the mixing blade includes a blade and multiple mixing protrusions on both sides of the blade, the blade is arranged perpendicular to the mixing shaft, and the multiple mixing protrusions are spaced apart in the extending direction of the blade, the multiple mixing protrusions include at least two first mixing protrusions on the first side of the blade and at least two second mixing protrusions on the second side of the blade, the blade can separate the material into two parts located on both sides of the blade during the rotation of the mixing blade around the axis of the mixing shaft, avoiding material adhesion, and causing the material between two adjacent blades to be mixed by the mixing action of at least two first mixing protrusions on one blade and at least two second mixing protrusions on the other blade. Since the at least two first mixing protrusions and at least two second mixing protrusions are staggered in the extending direction of the blade, the mixing action of the material between two adjacent blades from the first mixing protrusions and the mixing action from the second mixing protrusions are misaligned in the extending direction of the mixing blade, thereby causing the material to be torn, further avoiding material adhesion, improving the mixing effect of the material, and improving the mixing efficiency of the mixing machine.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] like Figures 1 to 4 As shown, this embodiment of the invention provides a turning mixer, which includes a frame 10, a traveling member 20, a turning shaft 30, a stirring drive member 40, and multiple turning blades 50. The traveling member 20 is mounted on the frame 10. The turning shaft 30 is horizontally mounted and rotatably mounted on the frame 10 around its axis. The stirring drive member 40 is mounted on the frame 10 and drivenly connected to the turning shaft 30 to drive the turning shaft 30 to rotate. The multiple turning blades 50 are spaced apart on the turning shaft 30 along its axial direction. The mixing blade 50 includes a blade 51 and a plurality of tumbling protrusions disposed on both sides of the blade 51. The blade 51 is disposed perpendicular to the tumbling shaft 30. The plurality of tumbling protrusions are spaced apart in the radial direction of the tumbling shaft 30. The plurality of tumbling protrusions include at least two first tumbling protrusions 52 disposed on the first side of the blade 51 and at least two second tumbling protrusions 53 disposed on the second side of the blade 51. The at least two first tumbling protrusions 52 and the at least two second tumbling protrusions 53 are staggered in the extending direction of the blade 51.

[0036] Using the mixing machine provided in this embodiment, the traveling component 20 drives the frame 10 to move horizontally on the ground where the material to be dried is laid. At the same time, the stirring drive component 40 drives the mixing shaft 30 to rotate. The mixing shaft 30 drives the mixing blades 50 to rotate around the axis of the mixing shaft 30. The mixing blades 50 are used to mix the material to be dried, thereby accelerating the drying speed of the material.

[0037] The mixing blade 50 includes a blade 51 and multiple mixing protrusions on both sides of the blade 51. The blade 51 is arranged perpendicular to the mixing shaft 30, and the multiple mixing protrusions are spaced apart in the extending direction of the blade 51. The multiple mixing protrusions include at least two first mixing protrusions 52 on the first side of the blade 51 and at least two second mixing protrusions 53 on the second side of the blade 51. Thus, during the rotation of the mixing blade 50 around the axis of the mixing shaft 30, the blade 51 can separate the material into two parts located on both sides of the blade 51, avoiding material adhesion, and causing the material located between two adjacent blades 51 to be mixed by at least two first mixing protrusions 52 on one blade 51 and at least two second mixing protrusions 53 on the other blade 51.

[0038] At the same time, since at least two first stirring protrusions 52 and at least two second stirring protrusions 53 are staggered in the extension direction of the blade 51, the stirring action of the material between two adjacent blades 51 from the first stirring protrusions 52 and the stirring action from the second stirring protrusions 53 are staggered in the extension direction of the stirring blade 50, thereby causing the material to be torn, further preventing the material from sticking together, improving the stirring effect of the material, and improving the stirring efficiency of the stirring machine.

[0039] It should be noted that the first side and the second side of blade 51 refer to the two sides of blade 51 in the axial direction of the stirring shaft 30, and the extension direction of blade 51 refers to... Figure 4 The X direction (the radial direction of the stirring shaft 30 corresponding to the position of blade 51).

[0040] like Figure 3 and Figure 4As shown, the first stirring protrusion 52 includes a first stirring plate 521, and the second stirring protrusion 53 includes a second stirring plate 531. The first stirring plate 521 and the second stirring plate 531 are both arranged perpendicular to the blade 51, and the first stirring plate 521 and the second stirring plate 531 are both arranged at an angle to the extension direction of the blade 51. The use of the first mixing plate 521 and the second mixing plate 531 can increase the contact area between the first mixing protrusion 52 and the second mixing protrusion 53 and the material, thereby more thoroughly mixing the material. Since the first mixing plate 521 and the second mixing plate 531 are both set at an angle to the extension direction of the blade 51, during the rotation of the mixing blade 50 around the axis of the mixing shaft 30, on the one hand, it can increase the effective pushing area of ​​the first mixing plate 521 and the second mixing plate 531 on the material, and on the other hand, it can separate the material on both sides of the first mixing plate 521 and the material on both sides of the second mixing plate 531, and can break up large pieces of material, avoid material sticking, improve the mixing effect of the material, and improve the mixing efficiency of the mixing machine.

[0041] like Figure 4 As shown, the angle between the first stirring plate 521 and the extending direction of the blade 51 is between 30° and 40°, and the angle between the second stirring plate 531 and the extending direction of the blade 51 is between 30° and 40°. By using the angles between the first stirring plate 521 and the extending direction of the blade 51, and the angle between the second stirring plate 531 and the extending direction of the blade 51, during the rotation of the stirring blade 50 around the axis of the stirring shaft 30, the effective pushing area of ​​the first stirring plate 521 and the second stirring plate 531 on the material can be increased, and the material on both sides of the first stirring plate 521 and the second stirring plate 531 can be effectively separated, thus improving the stirring effect.

[0042] The angle between the first stirring plate 521 and the extending direction of the blade 51 can be any value between 30°, 32°, 34°, 36°, 38°, 40° and 30° to 40°, and the angle between the second stirring plate 531 and the extending direction of the blade 51 can be any value between 30°, 32°, 34°, 36°, 38°, 40° and 30° to 40°.

[0043] Specifically, in this embodiment, the angle between the first stirring plate 521 and the extending direction of the blade 51 and the angle between the second stirring plate 531 and the extending direction of the blade 51 are both 35°.

[0044] like Figure 4As shown, the distance between adjacent first mixing plates 521 and second mixing plates 531 in the extending direction of blade 51 is between 3cm and 8cm. Using the first mixing plates 521 and second mixing plates 531 within the above-mentioned spacing range allows for thorough mixing of long strips of materials (similar to straw fibers) and small particles (similar to gravel), preventing long strips of materials from tangling on the first mixing plate 521 and / or the second mixing plate 531, avoiding equipment malfunctions, preventing dead zones in the mixing of small particles, and improving mixing uniformity.

[0045] The distance between adjacent first mixing plates 521 and second mixing plates 531 in the extending direction of blade 51 can be any value between 3cm, 4cm, 5cm, 6cm, 7cm, 8cm and 3cm to 8cm.

[0046] Specifically, in this embodiment, the distance between adjacent first mixing plates 521 and second mixing plates 531 in the extending direction of blade 51 is 7cm.

[0047] like Figure 4 As shown, the dimensions of the first mixing plate 521 and the second mixing plate 531 in the extension direction of the blade 51 are both greater than or equal to the distance between adjacent first mixing plates 521 and second mixing plates 531 in the extension direction of the blade 51. Using the aforementioned dimensions for the first mixing plate 521 and second mixing plate 531 reduces dead zones during material mixing, improves the thoroughness of material mixing, reduces the number of mixing cycles required, and increases material mixing efficiency.

[0048] like Figure 4 As shown, the stirring blade 50 also includes an elastic plate 54. The elastic plate 54 is disposed on the front side of the blade 51 and located at the end of the blade 51 away from the stirring shaft 30. The elastic plate 54 is perpendicular to the blade 51 and protrudes from the blade 51 in the extending direction of the blade 51. With the above-mentioned elastic plate 54, when the stirring blade 50 rotates clockwise around the axis of the stirring shaft 30, the elastic plate 54 first contacts the material. And because the elastic plate 54 protrudes from the blade 51 in the extending direction of the blade 51, the elastic deformation of the elastic plate 54 can be used to make good contact between the stirring blade 50 and the ground. On the one hand, this avoids a stirring blind zone between the end of the stirring blade 50 away from the stirring shaft 30 and the ground. On the other hand, the elastic deformation of the elastic plate 54 avoids damage to the ground or the stirring blade 50.

[0049] like Figure 4As shown, the stirring blade 50 also includes a reinforcing plate 55, which is disposed on the rear side of the blade 51 and located at the end of the blade 51 away from the stirring shaft 30. The reinforcing plate 55 is perpendicular to the blade 51 and protrudes from the blade 51 in the extending direction of the blade 51. The elastic plate 54 protrudes from the reinforcing plate 55 in the extending direction of the blade 51. With the above-mentioned reinforcing plate 55, when the stirring blade 50 rotates clockwise around the axis of the stirring shaft 30, the reinforcing plate 55 can play a role in auxiliary fixing the elastic plate 54, preventing the elastic plate 54 from falling off the blade 51 due to the resistance of the material.

[0050] like Figure 4 As shown, the cross-section of the elastic plate 54 in the radial direction of the stirring shaft 30 is an arc-shaped structure, and the middle part of the elastic plate 54 protrudes backward. With the above-mentioned arc-shaped structure, the elastic plate 54 can better push the material at the bottom layer when the stirring blade 50 rotates clockwise around the axis of the stirring shaft 30.

[0051] It should be noted that the cross section of the elastic plate 54 in the radial direction of the stirring shaft 30 refers to the cross section obtained by cutting the elastic plate 54 with a plane perpendicular to the axis of the stirring shaft 30.

[0052] like Figure 4 As shown, the rear edge 511 and the front edge 512 of the blade 51 are both arc-shaped edges. The middle part of the rear edge 511 protrudes backward, and the middle part of the front edge 512 is concave backward. The blade 51 with the above structure can increase the pushing area of ​​the blade 51 on the material, thereby making the material more thoroughly mixed.

[0053] In this embodiment, as Figure 4 As shown, the front side of blade 51 refers to the side that first contacts the material when blade 51 rotates clockwise around the axis of the mixing shaft 30, and the rear side of blade 51 refers to the side that last contacts the material when blade 51 rotates clockwise around the axis of the mixing shaft 30.

[0054] In this embodiment, the blade 51 is sickle-shaped in general. The end of the blade 51 away from the mixing shaft 30 is tilted forward relative to the end of the blade 51 facing the mixing shaft 30. The forward tilt angle of the end of the blade 51 away from the mixing shaft 30 relative to the end of the blade 51 facing the mixing shaft 30 is between 20° and 25°.

[0055] The forward tilt angle A4 of the end of blade 51 away from the mixing shaft 30 relative to the end of blade 51 facing the mixing shaft 30 can be any value between 20°, 21°, 22°, 23°, 24°, 25° and 20° to 25°.

[0056] Specifically, in this embodiment, the forward tilt angle of the end of the blade 51 away from the stirring shaft 30 relative to the end of the blade 51 facing the stirring shaft 30 is 23°.

[0057] like Figure 4 As shown, the front end of the tumbling protrusion is flush with the front edge 512 of the blade 51. When the tumbling blade 50 rotates in the forward direction around the axis of the tumbling shaft 30, the front end of the tumbling protrusion and the front edge of the blade 51 simultaneously come into contact with the material, increasing the pushing area of ​​the material and improving the tumbling effect.

[0058] like Figure 4 As shown, an arc-shaped base 513 is provided at the end of the blade 51 facing the stirring shaft 30. The arc-shaped base 513 is attached to the outer wall of the stirring shaft 30 and is detachably connected to the stirring shaft 30. The aforementioned arc-shaped base 513 facilitates the installation of the blade 51 onto the stirring shaft 30, and the detachable connection between the arc-shaped base 513 and the stirring shaft 30 makes it convenient to disassemble the stirring blade 50 individually for maintenance and replacement.

[0059] In this embodiment, the arc-shaped base 513 and the stirring shaft 30 are connected by fasteners.

[0060] The distance between two adjacent mixing blades 50 along the axial direction of the mixing shaft 30 is between 15cm and 25cm. Using multiple mixing blades 50 with this spacing range allows for thorough mixing of long, strip-shaped materials (similar to straw fibers) and small, granular materials (similar to gravel), preventing long, strip-shaped materials from becoming entangled on the mixing blades 50, thus avoiding equipment malfunctions and preventing dead zones in the mixing of small granular materials, thereby improving the uniformity of mixing.

[0061] The distance between two adjacent stirring blades 50 along the axial direction of the stirring shaft 30 can be any value between 15cm, 17cm, 19cm, 21cm, 23cm, 25cm, and 15cm to 25cm.

[0062] The included angle between two adjacent mixing blades 50 on the circumferential direction of the mixing shaft 30 is between 25° and 35°. Using multiple mixing blades 50 with the aforementioned spacing range allows for thorough mixing of long, strip-shaped materials (similar to straw fibers) and small, granular materials (similar to gravel), preventing long, strip-shaped materials from becoming entangled on the mixing blades 50, thus avoiding equipment malfunctions and eliminating dead zones in the mixing process for small granular materials, thereby improving mixing uniformity.

[0063] The included angle between two adjacent stirring blades 50 on the axial direction of the stirring shaft 30 can be any value between 25°, 27°, 29°, 31°, 33°, 35° and 25° to 35°.

[0064] like Figure 1As shown, the turning shaft 30 includes at least two turning sub-shafts 31 detachably connected in its axial direction. Because the at least two turning sub-shafts 31 are detachably connected in the axial direction of the turning shaft 30, the number of turning sub-shafts 31 can be adjusted to change the operating span range of the turning shaft 30 according to different operating span requirements. Furthermore, if the turning shaft 30 is torn or deformed due to material resistance, only the torn or deformed turning sub-shaft 31 needs to be replaced, saving on manpower, financial resources, and materials. Moreover, when transporting the turning shaft 30, the loading and unloading of the turning shaft 30 is flexible and does not require a transport vehicle that is compatible with the overall length of the turning shaft 30.

[0065] The ratio of the length of the mixing shaft 31 to the length of the mixing shaft 30 is between 20% and 30%. By adopting the above-mentioned ratio, the disassembly and maintenance costs of the mixing shaft 31 can be reduced without affecting the kinetic energy transmission effect between the mixing shafts 31.

[0066] The ratio of the length of the mixing shaft 31 to the length of the mixing shaft 30 can be any value between 20%, 22%, 24%, 26%, 28%, 30%, and 20% to 30%.

[0067] Specifically, in this embodiment, the ratio of the length of the stirring shaft 31 to the length of the stirring shaft 30 is 25%.

[0068] like Figure 1 As shown, the stirring shaft 30 also includes a flexible coupling 32, through which two adjacent stirring sub-shafts 31 are connected. Using the aforementioned flexible coupling 32 allows the two adjacent stirring sub-shafts 31 to transmit torque, avoiding resonance. Furthermore, the elastic deformation generated by the spring plates of the flexible coupling 32 during torque transmission can dampen vibrations, reducing the risk of deformation or even damage to the stirring sub-shafts 31 due to excessive load.

[0069] In this embodiment, the flexible coupling 32 is a serpentine spring coupling.

[0070] In this embodiment, the stirring shaft 31 is a hollow shaft, and the ratio of the outer diameter to the length of the stirring shaft 31 is between 5% and 10%. By using a stirring shaft 31 with the above-mentioned ratio range, the weight of the stirring shaft 31 and the kinetic energy consumed by the stirring shaft 31 rotating around its axis can be reduced, and the risk of twisting and deformation of the stirring shaft 31 can be reduced.

[0071] The ratio of the outer diameter of the mixing shaft 31 to the length of the mixing shaft 31 can be any value between 5%, 6%, 7%, 8%, 9%, 10%, and 5% to 10%.

[0072] In this embodiment, the stirring shaft 30 also includes a split-shaft detection component. The emitting and receiving ends of the split-shaft detection component are respectively disposed at both ends of the stirring split shaft 31 and located within the hollow cavity of the stirring split shaft 31. Using the aforementioned split-shaft detection component, the straightness of the stirring split shaft 31 can be detected. The emitting and receiving ends of the split-shaft detection component are parallel and on the same horizontal line. The laser beam is transmitted through the hollow cavity of the stirring split shaft 31. When the stirring split shaft 31 deforms due to excessive load, the emitting and receiving ends of the split-shaft detection component become misaligned. The receiving end of the split-shaft detection component cannot receive the laser beam emitted by the emitting end of the split-shaft detection component. The split-shaft detection component feeds the signal back to the control system, which controls the stirring machine to stop via a PLC program. The PLC program numbers the split-shaft detection components for each stirring split shaft 31. When the machine stops due to deformation, the control system page displays the location number of the split-shaft detection component corresponding to the damaged stirring split shaft 31, thereby accurately locating the fault and performing targeted repairs.

[0073] like Figure 1 As shown, the frame 10 includes a base 11 and a beam 12 mounted on the base 11. The beam 12 extends axially along the turning shaft 30. The beam 12 includes at least two sub-beams 121 corresponding to at least two turning shafts 31. The at least two sub-beams 121 are detachably connected axially along the turning shaft 30. The traveling member 20 is mounted on the base 11. The beam 12 provides support for the turning shaft 30. Since the at least two sub-beams 121 are detachably connected axially along the turning shaft 30, the number of sub-beams 121 can be increased and adjusted to accommodate different operating spans of the turning shaft 30. Furthermore, the beam 12 can be loaded and unloaded flexibly without requiring a transport vehicle with a length that is compatible with the beam 12.

[0074] In this embodiment, there are two seats 11, which are respectively located at both ends of the beam 12, and the two ends of the stirring shaft 30 are rotatably connected to the two seats 11 respectively.

[0075] like Figure 1 As shown, multiple agitator blades 50 are spirally arranged around the agitator shaft 31, with the two agitator blades 50 located at opposite ends of the agitator shaft 31 overlapping circumferentially. This arrangement of agitator blades 50 ensures that only half of each blade on the agitator shaft 31 contacts the material during agitation, reducing the agitation resistance of the agitator shaft 31 and lowering the equipment load.

[0076] like Figure 1As shown, the beam 12 also includes a support frame 122 disposed at the connection of two adjacent sub-beams 121. The support frame 122 extends downward, and its lower end is rotatably connected to the connection of two adjacent turning sub-shafts 31. Since the upper end of the support frame 122 is connected to the connection of two adjacent sub-beams 121, and the lower end of the support frame 122 is rotatably connected to the connection of two adjacent turning sub-shafts 31, the weight of the turning sub-shafts 31 can be transferred to the sub-beams 121 through the support frame 122 without affecting the rotation of the turning sub-shafts 31. This provides auxiliary support for the turning sub-shafts 30, improves the coaxiality between adjacent turning sub-shafts 31, and prevents the turning sub-shafts 31 from falling off.

[0077] In this embodiment, the beam 12 also includes a rubber gasket sandwiched between two adjacent sub-beams 121. The rubber gasket can buffer the impact between two adjacent sub-beams 121.

[0078] In this embodiment, the stirring drive includes a drive motor and a transmission component. The drive motor is mounted on the frame, and its drive shaft is connected to the end of the stirring shaft 30 via the transmission component. The drive motor provides power to the stirring shaft 30 through the transmission component.

[0079] In this embodiment, the stirring drive also includes a reducer, and the transmission component includes a drive sprocket, a transmission chain, and a driven sprocket. The drive shaft of the drive motor drives the drive sprocket to rotate through the reducer. The driven sprocket is located at the end of the tumbling shaft 30, and the transmission chain is sleeved on the drive sprocket and the driven sprocket to achieve stable and uniform rotation of the tumbling shaft 30.

[0080] In this embodiment, the walking component 20 includes walking wheels and a walking drive component. The walking wheels are disposed at the lower end of the frame, and the walking drive component is disposed on the frame and drivenly connected to the walking wheels.

[0081] In this embodiment, the thickness of the first stirring plate 521 and the second stirring plate 531 is 8mm, the dimension of the first stirring plate 521 and the second stirring plate 531 in the direction perpendicular to the blade 51 is 150mm, the length of the first stirring plate 521 and the second stirring plate 531 in the direction parallel to the blade 51 is 100mm, the thickness of the elastic plate 54 is 6mm, the dimension of the elastic plate 541 in the direction perpendicular to the blade 51 is 300mm, the arc length of the elastic plate 54 in the direction parallel to the blade 51 is 100mm, the chord length of the elastic plate 54 in the direction parallel to the blade 51 is 70mm, the length of the stirring shaft 31 is 3940mm, the outer diameter of the stirring shaft 31 is 200mm, the length of the stirring shaft 30 is 17200mm, and the wall thickness of the stirring shaft 31 is 7mm.

[0082] In this embodiment, there are two first stirring protrusions 52 and three second stirring protrusions 53.

[0083] The mixing machine provided in this embodiment has the following beneficial effects:

[0084] (1) At least two first stirring protrusions 52 and at least two second stirring protrusions 53 are staggered in the extension direction of the blade 51. The first stirring plate 521 and the second stirring plate 531 are both set at an angle to the extension direction of the blade 51. An elastic plate 54 is provided on the blade 51 to improve the stirring effect of the material and improve the stirring efficiency of the stirring machine.

[0085] (2) According to the needs of different operating span ranges, the number of turning and mixing sub-shafts 31 can be increased to change the operating span range of the turning and mixing shaft 30. At the same time, if the turning and mixing shaft 30 is twisted and deformed due to material resistance, only the twisted and deformed turning and mixing sub-shaft 31 needs to be replaced, saving the waste of manpower, financial resources and materials. Furthermore, when transporting the turning and mixing shaft 30, the loading and unloading of the turning and mixing shaft 30 can be flexible and there is no need to adapt the transport vehicle to the total length of the turning and mixing shaft 30.

[0086] (3) The two adjacent mixing shafts 31 transmit torque through the flexible coupling 32 to avoid resonance. Multiple mixing blades 50 are spirally arranged on the mixing shaft 31 to reduce the mixing resistance of the mixing shaft 31 and reduce the large vibration caused by high load.

[0087] Among related technologies, soil turning machines are widely used in agriculture and animal husbandry. Due to their inherent characteristics of customization and easily damaged parts, there are many types of soil turning machines, which can be categorized into five types: straddle-mounted, front-loading, towed, three-wheeled, and rail-mounted.

[0088] (1) The straddle-type compost mixer straddles a pre-piled long strip of compost base, and the rotating cutter shaft mounted under the frame of the straddle-type compost mixer mixes the compost base material. The advantages of the straddle-type compost mixer are that the whole machine has a compact structure, good rigidity and balanced force, high mixing efficiency, and the mixed windrows are uniform, neat and tightly arranged. The disadvantages of the straddle-type compost mixer are that long-distance transfer requires a trailer, the size of the windrows is limited by the machine model, and the equipment cost is relatively high.

[0089] (2) The front-loading turning machine uses a general loader as the main driving host and replaces the loader's bucket with a turning device, providing a new field for the application of the loader. The front-loading turning machine is mainly used for composting urban domestic waste. The advantages of the front-loading turning machine are good mobility, flexible operation, and convenient relocation.

[0090] (3) The towed compost turner is a device that is towed by a tractor and straddles a long strip of compost. The advantages of the towed compost turner are its simple structure, low cost, and easy acceptance by small farms and small-scale producers. It can be matched with various types of tractors, and long-distance relocation can be achieved by towing with a tractor without the need for a special trailer. The disadvantage of the towed compost turner is that the tractor travels between the stacks, which requires a large area and results in low site utilization.

[0091] (4) The three-wheeled turning and mixing machine is developed based on mature rolling mill technology combined with a three-wheeled vehicle device. It adopts a turning and piling method that moves the material laterally. During the movement, the material is rolled into the machine from the right side with a width of 1m through two relatively turning rollers installed between the front wheel and the rear axle, and then piled to the left side of the machine at a certain speed through an adjustable speed conveyor belt. The advantages of the three-wheeled turning and mixing machine are that it is flexible in movement and steering, highly mobile, can travel long distances without trailers, the driving lane is clean after grinding, the edges of the fertilizer pile are neat, and the material can be piled in patches to achieve the maximum site utilization rate.

[0092] (5) Track-type turning machine refers to a machine that uses a track-type rubber track propulsion system to ensure that the turning machine moves along the track without deviating. This turning machine is used in trough fermentation systems and is generally electrically driven.
