Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a crushing barrel which can prevent blade entanglement. Background Art

[0002] In many mechanical equipment, a crushing mechanism is often needed to crush the material in the barrel of the equipment. The structure of the crushing mechanism generally includes a driving motor arranged outside the barrel and a crushing blade arranged at the end of the driving shaft of the driving motor and located in the barrel.

[0003] In order to avoid direct scratching between the crushing blade and the bottom of the barrel, this type of structure is often designed to maintain a certain gap between the bottom of the crushing blade and the bottom of the barrel. This gap will in turn cause the drive shaft to be exposed. When crushing materials, such as long-sized cloth or sheets, it is easy for the gap and the traction force when the drive shaft rotates to cause such materials to be entangled on the drive shaft and rotate with the drive shaft, thereby affecting the overall crushing effect and even causing problems such as damage to the drive shaft due to the entanglement of the blade.

[0004] In view of this, the applicant has invented a utility model which has an ingenious structural design and can effectively prevent the knife from being entangled by adding an isolation turntable. Utility Model Content

[0005] The utility model aims to provide a crushing barrel with an anti-knife entanglement function, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A crushing barrel for preventing knife entanglement comprises an outer barrel and a crushing mechanism arranged at the bottom of the outer barrel, the crushing mechanism comprising an isolation turntable, a turntable driving motor and a crushing knife group arranged above the isolation turntable; the driving shaft of the turntable driving motor passes through the bottom of the outer barrel and the isolation turntable in sequence from the outside and is connected to the crushing knife group; the driving shaft above the isolation turntable is not exposed, the outer edge of the isolation turntable is arranged close to the inner side wall of the outer barrel, and an isolation ring is further concentrically arranged below the isolation turntable, and the lower edge of the isolation ring is arranged close to the inner bottom surface of the outer barrel.

[0008] As a further improvement, the crushing blade group includes a crushing blade and a fixed plate installed on the isolation turntable; the fixed plate is provided with a fixing hole adapted to be installed with the drive shaft, the top surface of the drive shaft is flush with the top surface of the fixed plate, and the crushing blade is installed on the fixed plate and / or the top surface of the drive shaft.

[0009] As a further improvement, the fixing plate is in the shape of an elongated strip, and the fixing hole is opened at the center, and both ends of the fixing plate are arranged close to the outer edge of the isolation turntable.

[0010] As a further improvement, at least one stirring blade is further arranged below the isolation turntable.

[0011] As a further improvement, the isolation ring further includes a fixed bracket installed below the isolation turntable, and the lower surface of the fixed bracket is equipped with two stirring blades that are symmetrically arranged with the axis of the driving shaft as the center.

[0012] As a further improvement, at least two evenly distributed push blocks are further provided on the inner side of the bottom of the outer barrel.

[0013] As a further improvement, the number of the push blocks is three, and the shape of the push blocks is a triangular prism.

[0014] As a further improvement, the isolation ring is arranged along the outer edge of the isolation turntable.

[0015] As a further improvement, the driving shaft includes a driving shaft and a driven shaft, and the crushing mechanism further includes a driving wheel sleeved on the driving shaft, a driven wheel sleeved on the driven shaft, and a transmission belt connecting the driving wheel and the driven wheel.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

In the description of the present utility model, the meaning of "several" is two or more, unless otherwise clearly and specifically defined.

[0027] Please refer to Figure 1 and Figure 2A crushing barrel for preventing knife entanglement comprises an outer barrel 11 and a crushing mechanism 20 arranged at the bottom of the outer barrel 11, wherein the crushing mechanism 20 comprises an isolation turntable 21, a turntable driving motor 22 and a crushing knife group 23 arranged above the isolation turntable 21; the driving shaft of the turntable driving motor 22 passes through the bottom of the outer barrel 11 and the isolation turntable 21 in sequence from the outside and is connected to the crushing knife group 23; the driving shaft is not exposed above the isolation turntable 21, the outer edge of the isolation turntable 21 is arranged close to the inner side wall of the outer barrel 11, and an isolation ring 24 is further concentrically arranged below the isolation turntable 21, and the lower edge of the isolation ring 24 is arranged close to the inner bottom surface of the outer barrel 11.

[0028] In this embodiment, the crushing barrel is a microwave processing equipment for treating medical solid waste. Since medical solid waste includes long-sized textiles such as gauze and bed sheets, it is easy for the blade to be entangled, so the crushing barrel can effectively solve the problem of blade entanglement in this application scenario; of course, any other crushing barrels that may cause blade entanglement can also directly apply the crushing mechanism.

[0029] The overall crushing mechanism performs preliminary separation of the drive shaft and the material through the isolation effect of the isolation turntable 21 to prevent the material from directly contacting the drive shaft. At the same time, secondary isolation is performed through the isolation ring 24 to prevent the material from further entering the gap between the isolation turntable 21 and the bottom of the outer barrel 11 after high-speed rotation and crushing, thereby completely avoiding the problem of knife entanglement.

[0030] Please refer to Figure 3 The crushing blade group includes a crushing blade 231 and a fixing plate 232 installed on the isolation turntable 21; the fixing plate 232 is provided with a fixing hole adapted to be installed with the driving shaft, the top surface of the driving shaft is flush with the top surface of the fixing plate 232, the crushing blade 231 is installed on the fixing plate 232 and / or the top surface of the driving shaft, the fixing plate 232 can be detachably fixed to the bottom of the outer barrel 11, and the crushing blade 231 can be detachably fixed to the fixing plate 232.

[0031] On the one hand, the driving shaft can be effectively surrounded by the fixing plate 232 to prevent the driving shaft from being exposed, and at the same time, it can have a certain driving effect on the material during rotation; on the other hand, the crushing blade 231 can also be fixed by the fixing plate 232. When the subsequent crushing blade 231 is damaged after being used for a period of time, the fixing plate 232 can be quickly disassembled to achieve the replacement of the entire crushing blade 231.

[0032] Please refer to Figure 2 and Figure 3The fixing plate 232 is in the shape of a long strip, and the fixing hole is opened in the center. Both ends of the fixing plate 232 are arranged close to the outer edge of the isolation turntable 21, and the thickness of the fixing plate 232 ranges from 3 cm to 5 cm. On the one hand, the fixing plate 232 with a certain thickness can effectively push the material, and on the other hand, the crushing blade 231 is adapted to the shape of the long strip fixing plate 232, which can effectively ensure the stable connection of the blade.

[0033] Please refer to Figure 4 At least one stirring blade 25 is further provided below the isolation turntable 21. The structure of the stirring blade 25 can effectively stir the accumulated liquid stored and flowing below the isolation turntable 21, so that it can be evaporated or thrown out better.

[0034] Furthermore, the isolation ring 24 further includes a fixed bracket 26 installed under the isolation turntable 21, and the fixed bracket 26 includes a horizontal fixed ring and a cross fixed frame horizontally fixed to the inner side of the horizontal fixed ring; the lower surface of the cross fixed frame of the fixed bracket 26 is installed with two stirring blades 25 symmetrically arranged with the axis of the driving shaft as the center, and the stirring blades 25 are inclined.

[0035] The two stirring blades 25 can more effectively and evenly stir the accumulated liquid, so that it can evaporate or be thrown out quickly; at the same time, the cross fixing frame cooperates with the horizontal fixing ring to stably support and fix the isolation disc.

[0036] Please refer to Figure 2 and Figure 3 At least two evenly distributed push blocks 27 are further provided on the inner side of the bottom of the outer barrel 11. The push blocks 27 are detachably provided to further provide thrust to the material in the barrel from the side, so as to cooperate with the crushing blade 231 to better crush the material.

[0037] Furthermore, the number of the push blocks 27 is three and they are evenly arranged. The height of the push blocks 27 is located in the lower half of the outer barrel 11. The shape of the push blocks 27 is a triangular prism. One side of the triangular prism is fitted to the inner wall of the outer barrel 11, and the other two side surfaces are exposed. The structure can effectively realize the effective pushing of materials regardless of forward or reverse rotation.

[0038] Please refer to Figure 3 , the isolation ring 24 is arranged along the outer edge of the isolation turntable 21. Through this structure, the space between the isolation ring 24 and the inner wall of the outer barrel 11 can be minimized, thereby avoiding the possibility of materials running under the isolation turntable 21 as much as possible.

[0039] Please refer to Figure 4The driving shaft includes a driving shaft and a driven shaft, and the crushing mechanism 20 further includes a driving wheel sleeved on the driving shaft, a driven wheel sleeved on the driven shaft, and a transmission belt connecting the driving wheel and the driven wheel. Due to the weight of the isolation turntable 21 and the material being processed, direct driving is difficult, so the torque is increased by belt transmission.

[0040] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
