DETAILED DESCRIPTION

[0023] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0024] As shown in Figures 1-7 The utility model provides a cantilever double cone spiral mixing machine, including the warehouse body 1 of cone, two screw rods 2 rotate along the inner side wall of warehouse body 1, and the screw rod 2 is all driven by drive arrangement, and the sidewall of warehouse body 1 is equipped with extrusion device 22, and extrusion device 22 includes extrusion groove 3, and extrusion groove 3 is connected with extrusion plate 4 through a plurality of telescopic links 5, and the axis of telescopic link 5 is parallel with the diameter direction of warehouse body 1, and the slot bottom of extrusion groove 3 is equipped with pusher plate 6 between extrusion plate 4, and a plurality of moving holes are equipped on pusher plate 6, and telescopic link 5 is penetrated pusher plate 6 by moving hole, and spring 7 is sleeved on telescopic link 5 between pusher plate 6 and slot bottom, and drive arrangement is connected with middle shaft 8, and middle shaft 8 is placed in one end of warehouse body 1 and is fixed with driving disc 9, and driving disc 9 is fixed with eccentric shaft 10, and eccentric shaft 10 is hinged with rocker 11, and rocker 11 can drive extrusion plate 4 to approach or away from extrusion groove 3.

[0025] In the use, the material that needs to be mixed is added to the warehouse body 1 from the feed inlet of warehouse body 1, and the two screw rods 2 are driven by the drive arrangement, so that the two screw rods 2 not only revolve along the axis of the drive arrangement, but also rotate, which can overturn and stir the material in all directions without dead angle, ensuring that the material reaches a highly uniform mixing state in a short time, improving the mixing efficiency and ensuring the mixing quality. During the rotation of the drive arrangement, the drive arrangement drives the middle shaft 8 to rotate, and the middle shaft 8 cooperates with the driving disc 9, the eccentric shaft 10 and the rocker 11 to form a crank rocker 11 mechanism, so that the rocker 11 can drive the extrusion plate 4 to move along the telescopic link 5. When the extrusion plate 4 approaches the extrusion groove 3, the extrusion plate 4 pushes the material into the extrusion groove 3, and the edge of the extrusion plate 4 and the extrusion groove 3 cooperate to apply a certain shearing force to the material, and the pusher plate 6 compresses the spring 7 through the material, so that the spring 7 is compressed to the extreme. The pusher plate 6 and the extrusion plate 4 cooperate to extrude the material, which helps to break the agglomerated structure of the material and improve the fineness and uniformity of the material. When the extrusion plate 4 moves away from the extrusion groove 3, the spring 7 pushes the pusher plate 6, so that the extruded material can re-enter the warehouse body 1 for sufficient stirring. The spring 7 pushes the pusher plate 6 to send the extruded material back into the warehouse body 1 for further stirring. This process not only realizes the cyclic mixing of the material, but also ensures that the crushed material can fully mix with other materials, further improving the mixing effect.

[0026] As shown in Figures 3-6As shown, the trough bottom of the extrusion groove 3 is provided with a through groove 12, and a support plate 13 is slidably arranged in the through groove 12. The support plate 13 can seal the through groove 12. The pushing plate 6 is a hole plate, and one end of the support plate 13 close to the pushing plate 6 is slidably connected with a blocking block 14. When the spring 7 is compressed, the blocking block 14 can block the hole plate. The extrusion groove 3 is provided with a discharge port 15 below.

[0027] During normal use, the blocking block 14 blocks the hole plate, the hole plate normally extrudes the material and pushes the material out of the extrusion groove 3, so that the material participates in stirring. When it is necessary to discharge the material, the blocking block 14 is only pulled out, at this time, a channel is formed between the hole plate and the support plate 13, the material passing through the hole plate slides along the channel to the discharge port 15 and is discharged, so that the material is discharged more conveniently and quickly. When it is necessary to clean the hole plate and the extrusion groove 3, the support plate 13 is pulled out to open the through groove 12, so that the hole plate and the inside of the extrusion groove 3 are conveniently accessed and cleaned, the difficulty and time consumption of cleaning work are reduced, and the maintenance efficiency of the equipment is improved.

[0028] As shown in Figure 4 , the screw rod 2 includes a fixed rod 16 and a plurality of clamping rods 26. The fixed rod 16 is connected with the driving device, the fixed rod 16 is clamped with the clamping rod 26, each clamping rod 26 can be clamped with each other, and the pitches of the fixed rod 16 and the clamping rod 26 are different. The clamping mode is not limited, and the detachable fixed connection between the fixed rod 16 and the clamping rod 26 can be ensured.

[0029] The pitches of the fixed rod 16 and the clamping rod 26 can be replaced, so that the most suitable screw blade segment can be flexibly selected or adjusted according to different mixing tasks and material characteristics, so that the mixer can more accurately adapt to various mixing requirements, and the flexibility and accuracy of mixing are improved. Through the detachable clamping connection mode, the replacement and maintenance of the fixed rod 16 and the clamping rod 26 become more simple and convenient, and when a part is damaged or needs to be replaced, the entire screw rod 2 does not need to be replaced, only the corresponding part needs to be replaced, thereby reducing the maintenance cost and time cost.

[0030] As shown in Figure 3 , 4 , 8, 9, the driving device includes a liftable motor 23, a plurality of flat keys 18 are arranged in a spiral array on a driving shaft of the motor 23, the driving shaft of the motor 23 is connected with the middle shaft 8 through a key, and the screw rod 2 is fixed with a connecting ring 19 through a connecting rod 17 at one end outside the bin body 1. The connecting rings 19 are arranged in an upper and lower interlaced manner, the axes of the connecting rings 19 all coincide with the axis of the driving shaft of the motor 23, the connecting rings 19 are provided with key grooves 20 matched with the flat keys 18, and the screw shafts are all fixed with driving motors 21 at one end outside the bin body 1. The liftable motor 23 is a prior art, such as a hydraulic rod driving the motor 23 to lift.

[0031] In use, the flat key 18 is lifted and lowered by the lifting motor 23, so that the connecting ring 19 can be connected with the flat key 18 at different angles, thereby achieving the effect of adjusting the relative position of the two screw shafts, and the material can be turned and stirred more effectively, and the stirring efficiency is improved. By setting the driving motor 21, more flexible mixing control can be achieved, for example, by adjusting the speed and direction of rotation of the two motors 23 to change the mixing mode and flow direction of the material, so as to ensure that the material achieves the best uniformity and consistency during mixing.

[0032] As shown in Figure 3 , 5 , the circumferential array of the bin body 1 has a plurality of extrusion devices 22, and the eccentric shaft 10 is a crankshaft, and a plurality of rocker arms 11 are hinged on the crankshaft, and the rocker arms 11 correspond one-to-one with the material pressing devices. By arranging a plurality of extrusion devices 22 in a circumferential array on the bin body 1, the material in the bin body 1 can be extruded at multiple points at the same time, not only increasing the extrusion area, but also improving the uniformity of extrusion, thereby ensuring that the material can be subjected to sufficient extrusion, which helps to improve the mixing efficiency and quality. As a single power input point, the crankshaft can drive a plurality of extrusion devices 22 to work at the same time through the transmission action of the rocker arms 11, thereby achieving effective transmission and distribution of power.

[0033] As shown in Figure 3 , 5 , the side wall of the upper end of the central shaft 8 is fixed with a connecting rod 24, the end of the connecting rod 24 is connected with a scraper 25, and the scraper 25 abuts against the inner side wall of the bin body 1. The scraper 25 can closely abut against the inner side wall of the bin body 1, and as the central shaft 8 rotates, the scraper 25 can continuously scrape the bin wall, thereby effectively removing the material residues attached to the inner wall of the bin body 1. This avoids the accumulation and caking of the material on the inner wall of the bin body 1, and maintains the cleanliness of the bin body 1. The scraper 25 can continuously clean the bin wall, ensuring that the material can flow freely during mixing, which helps to improve the mixing uniformity and efficiency of the material.
