Description

Technical Field

[0001] The present application belongs to the technical field of equipment for feed production, and in particular, relates to a crushing device for producing special feed for yellow catfish. Background Art

[0002] Pelteobagrus fulvidraco is a relatively common carnivorous freshwater fish. The raw materials of its special feed mainly include fish meal, soybean meal, rapeseed meal, fish oil, corn meal, and rice bran.

[0003] Among them, fish meal, corn meal and rice bran can be used directly after purchase, while soybean meal and rapeseed meal are generally large blocks, which need to be crushed after purchase to make them into qualified powder with moderate particle size. In the above crushing operation, a crushing device is needed. The common existing crushing device mainly includes a cylinder, a cover plate, a bottom plate, a motor, a rotating shaft, and a crushing knife. Large pieces of soybean meal, such as soybean meal, are put into the feed port on the cover plate and fall down, and multiple crushing knives can cut and crush them, so that relatively small soybean meal powder is obtained at the discharge port on the bottom plate. The above-mentioned cutting and crushing operation can be repeated many times to ensure that the soybean meal and rapeseed meal have a sufficiently small powder particle size.

[0004] However, the above common pulverizing devices have many impractical and inefficient problems during use. For example, the materials stuck on the annular surface of the cylinder are difficult to clean, and long-term accumulation easily leads to the problem of polluting the internal environment of the device.

[0005] Correspondingly, various new types of crushing devices that can specifically remove the above-mentioned sticky materials have also appeared. For example, the Chinese utility model patent with application announcement number CN211636742U and authorization announcement date of October 9, 2020, discloses a crusher for processing yellow catfish aquaculture feed, whose structure includes a crushing bin, a movable plate, a first hydraulic cylinder, a collecting bin, a chute, a slider, a crushing paddle, a crushing rod, a scraper, a lifting ring, a connecting rod, a second hydraulic cylinder, a mounting plate, a crushing motor, and a movable door.

[0006] The pulverizer in this utility model patent has the following advantages: the raw materials can be fully pulverized, the pulverization efficiency is improved, and it is convenient and hygienic.

[0007] However, in actual use, the pulverizer still has at least the following inefficiencies and impracticalities, specifically: The stroke of the second hydraulic cylinder is very limited, and can only allow the lifting ring and the scraper to descend a relatively small distance. If material adheres to the relatively lower area of ​​the inner ring surface of the crushing bin, it is difficult for the scraper to remove it. Summary of the invention

[0008] The present application provides a pulverizing device for producing special feed for yellow catfish, and the technical problem to be solved is: how to completely and fully remove the materials stuck on the inner ring surface of the device.

[0009] The technical solution adopted by the present application to solve the above-mentioned problem is: a crushing device for producing special feed for yellow catfish, the structure of which includes a cylinder, a rotating shaft, a cover plate, a motor, a bottom plate, a bottom plate discharge port, and a crushing knife, and also includes a limit ring unit arranged on the upper surface of the bottom plate and used to sleeve the rotating shaft, a tubular rotating frame unit arranged on the limit ring unit and used to flush the residual material on the inner ring surface of the cylinder, and a locking ring unit arranged on the cover plate and used to insert the tubular rotating frame unit.

[0010] A further preferred technical solution is that the limiting ring unit includes a fixing plate arranged on the upper surface of the bottom plate, and a limiting ring arranged on the fixing plate and located below all the crushing knives and used for sleeve-engaging the rotating shaft.

[0011] A further preferred technical solution is that the limiting ring unit also includes an open circular ring arranged on the fixing plate and used for mounting the tubular rotating frame unit.

[0012] A further preferred technical solution is that the tubular rotating frame unit includes a circular ring tube that is snap-fitted onto the open circular ring, a vertical tube that is arranged on the circular ring tube and has its upper end inserted into the snap-fitting ring unit, and an opening that is arranged on the vertical tube and is used to flush the inner annular surface of the cylinder.

[0013] A further preferred technical solution is that: the bottom plate is an inclined plate; the tubular rotating frame unit also includes a perforated pipe arranged between the annular pipe and the vertical pipe and used for flushing the bottom plate.

[0014] A further preferred technical solution is that the tubular rotating frame unit also includes a water inlet pipe which is arranged on the annular tube, passes through the bottom plate discharge port, and is used to rotationally drive the annular tube.

[0015] A further preferred technical solution is that the locking ring unit includes an annular hole provided on the cover plate and used to pass the vertical tube, and a protruding ring provided on the upper surface of the cover plate and having an inverted U-shape in vertical cross section and used to insert into the vertical tube.

[0016] A further preferred technical solution is that: a limiting ring is sleeved on the motor, and a limiting support rod for engaging with the inner ring surface of the protruding circular ring is provided on the limiting ring.

[0017] A further preferred technical solution is that: a filter screen with a frame is also provided on the bottom plate discharge port, and a connecting column is provided between the filter screen with a frame and the bottom plate discharge port.

[0018] A further preferred technical solution is that: the connecting column is also provided with an elastic protective sleeve for filter vibration for receiving the rotational impact force of the water inlet pipe.

[0019] The beneficial effects of this application include at least the following four points.

[0020] First, the device has a comprehensive flushing effect on the inner ring surface of the cylinder, ensuring that the residual materials on the inner ring surface can be fully removed and dropped, and then recycled.

[0021] Second, the tubular rotating frame unit can be ventilated or water can be passed through it, both of which have the above-mentioned comprehensive flushing effect, so the practicality and flexibility are relatively high.

[0022] Third, the tubular rotating frame unit has a stable and reliable flushing and rotating action, is not easy to shift vertically or horizontally, and will not affect the rotating crushing effect of the crushing knife.

[0023] Fourth, both the rotating shaft and the motor have lateral limiting effects, ensuring that the former rotates accurately and the latter does not swing easily. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] The following description is merely a preferred embodiment of the present application and does not limit the scope of the present application.

[0037] like Figure 1-Figure 10 As shown, a crushing device for producing special feed for yellow catfish includes a cylinder 11, a rotating shaft 12, a cover plate 13, a motor 14, a bottom plate 15, a bottom plate discharge port 16, and a crushing knife 17, and also includes a limit ring unit 1 arranged on the upper surface of the bottom plate 15 and used to sleeve the rotating shaft 12, a tubular rotating frame unit 2 arranged on the limit ring unit 1 and used to flush the residual material on the inner ring surface of the cylinder 11, and a locking ring unit 3 arranged on the cover plate 13 and used to insert the tubular rotating frame unit 2.

[0038] In this embodiment, the cover plate 13 is further provided with a feed port 18 and an axis through hole 19. Large pieces of material such as soybean meal pass through the feed port 18 and the crushing knife 17 in sequence, and then become small particles and fall on the bottom plate 15, and finally discharge at the bottom plate discharge port 16, completing the basic operation of crushing the entire feed raw material.

[0039] The main material of the device is stainless steel, the cylinder 11 and the bottom plate 15 are integrally formed, the motor 14, the rotating shaft 12 and the plurality of crushing knives 17 are connected as a whole and installed on the cover plate 13, and the cover plate 13 is buckled with the cylinder 11. The cylinder 11 and the cover plate 13 are both circular in shape, the shaft through hole 19 is located at the center of the cover plate 13, and the vertical projection of the feed port 18 falls within the rotating area of ​​the crushing knives 17.

[0040] On the other hand, the limiting ring unit 1 is screwed to the bottom plate 15, and the former has at least the following functions: First, the rotating shaft 12 is laterally limited to make its rotation more precise and avoid swinging, so as to prevent the crushing blade 17 from hitting the tubular rotating frame unit 2 and the cylinder 11; Second, as the installation and limiting part of the tubular rotating frame unit 2, it ensures that the tubular rotating frame unit 2 has an accurate rotation effect and will not shift horizontally or fall vertically.

[0041] In addition, the function of the tubular rotating frame unit 2 is mainly to flush the inner annular surface of the cylinder 11, flush the residual material a, and finally recycle it at the bottom plate discharge port 16. Among them, the overall vertical size of the tubular rotating frame unit 2 is larger than the cylinder 11, ensuring that all positions on the inner annular surface of the cylinder 11 can be effectively cleaned, and the lateral distance between the tubular rotating frame unit 2 and the inner annular surface of the cylinder 11 is 1-2cm, that is, the flushing distance. This distance is relatively small because: first, it ensures that the flushing operation has a greater intensity; second, it leaves a sufficient safety distance from the crushing knife 17 to prevent the crushing knife 17 from damaging the tubular rotating frame unit 2.

[0042] Finally, there is the snap-fit ​​ring unit 3, which is integrally formed with the cover plate 13, and its functions include at least: the upper end of the tubular rotating frame unit 2 is inserted into the snap-fit ​​ring unit 3 to prevent the tubular rotating frame unit 2 from harmful vertical displacement and lateral swing, so that it can only rotate accurately.

[0043] The limiting ring unit 1 includes a fixing plate 101 disposed on the upper surface of the bottom plate 15 , and a limiting ring 102 disposed on the fixing plate 101 , located below all the crushing knives 17 , and used for sleeve-engaging the rotating shaft 12 .

[0044] In this embodiment, the limiting ring 102, the cylinder 11, the cover plate 13, the bottom plate discharge port 16 and the shaft through hole 19 are all circular in shape, and the vertical projections of the center positions are overlapped as much as possible, ultimately ensuring that: the lower end of the rotating shaft 12, where the harmful swing phenomenon is most serious, can be accurately rotated, avoiding bending and deformation of the rotating shaft 12, avoiding damage to the crushing knife 17, and avoiding damage to the motor 14.

[0045] There are two fixing plates 101 , which are centrally symmetrically positioned on the limiting ring 102 and are screwed to the bottom plate 15 .

[0046] The limiting ring unit 1 further includes an open circular ring 103 which is arranged on the fixing plate 101 and is used for mounting the tubular rotating frame unit 2 .

[0047] In this embodiment, the central angle of the open circular ring 103 is greater than 180°, and the tubular rotating frame unit 2 can be manually pressed and inserted for installation, and is unlikely to fall out spontaneously.

[0048] The fixing plate 101 and the opening ring 103 are integrally formed, and there are two of them.

[0049] The tubular rotating frame unit 2 includes a circular ring tube 201 that is engaged with the open circular ring 103, a vertical tube 202 that is arranged on the circular ring tube 201 and has its upper end inserted into the engaged ring unit 3, and an opening 203 that is arranged on the vertical tube 202 and is used to flush the inner annular surface of the cylinder 11.

[0050] In this embodiment, the tubular rotating frame unit 2 is made of rubber, the annular tube 201 and the vertical tube 202 are integrally formed, the number of the vertical tubes 202 is 2-3, which are evenly spaced in the circumferential direction, and the length thereof is greater than the length of the cylinder 11. There are 1-2 rows of openings 203 on the vertical tubes 202 at positions facing the cylinder 11, so as to ensure that water or air is sprayed there, so as to efficiently wash away the residual material a.

[0051] The bottom plate 15 is an inclined plate; the tubular rotating frame unit 2 further includes a perforated pipe 204 disposed between the annular pipe 201 and the vertical pipe 202 and used for flushing the bottom plate 15 .

[0052] In this embodiment, the lowest point of the inclined upper surface of the bottom plate 15 is the plate discharge port 16 , so that the crushed material can be discharged completely and quickly at the plate discharge port 16 .

[0053] The hole-opening method and cleaning principle of the hole-opening tube 204 are consistent with those of the vertical tube 202 . The hole-opening tube 204 is parallel to the inclined upper surface of the bottom plate 15 , and the vertical tube 202 is parallel to the inner annular surface of the cylinder 11 .

[0054] Finally, the rotation area of ​​the perforated tube 204 is located at the opening position of the open ring 103. Therefore, the tubular rotating frame unit 2 can rotate a full circle or even multiple circles at this time, ensuring that the inner annular surface of the cylinder 11 and the upper surface of the bottom plate 15 have a complete cleaning effect.

[0055] The tubular rotating frame unit 2 further includes a water inlet pipe 205 which is arranged on the annular tube 201 , passes through the bottom plate discharge port 16 , and is used for rotating and driving the annular tube 201 .

[0056] In this embodiment, the upper end of the water inlet pipe 205 is fixedly connected to the annular tube 201, and the lower end is exposed to the outside of the bottom plate discharge port 16. The lower end is used to connect a water supply pump, or a water supply pump and a drive motor to ensure that the rotating cleaning action of the tubular rotating frame unit 2 is sufficiently efficient.

[0057] However, it should be noted that the tubular rotating frame unit 2 cannot rotate a full circle at this time, because the open ring 103 will block the water inlet pipe 205. Therefore, the tubular rotating frame unit 2 performs the residual material washing operation by reciprocating rotation, and the two end points of the reciprocating rotation action are that the water inlet pipe 205 touches the two open rings 103.

[0058] This method does not affect the above-mentioned comprehensive cleaning effect on the cylinder 11 and the bottom plate 15. If the number of the vertical pipes 202 is 3, the comprehensive cleaning effect will be more sufficient.

[0059] The snap-fit ​​ring unit 3 includes an annular hole 301 provided on the cover plate 13 and used to pass the vertical tube 202 , and a protruding ring 302 provided on the upper surface of the cover plate 13 and having an inverted U-shaped vertical cross-section and used to insert the vertical tube 202 .

[0060] In this embodiment, the width of the annular hole 301 is slightly larger than the outer diameter of the vertical tube 202, and the inner top surface of the protruding ring 302 appropriately blocks the upper end surface of the vertical tube 202 to avoid unnecessary large-scale air and water leakage at the upper end of the vertical tube 202. On the other hand, a plug can also be directly provided on the upper end surface of the vertical tube 202.

[0061] In addition, the inside of the protruding ring 302 can also provide lubricating grease to the blocked vertical tube 202, so that the rotation of the tubular rotating frame unit 2 is more precise.

[0062] The motor 14 is also sleeved with a limiting ring 4 , and the limiting ring 4 is also provided with a limiting support rod 5 for engaging with the inner ring surface of the protruding circular ring 302 .

[0063] In this embodiment, the number of the limiting support rods 5 is 2-4, which are integrally formed with the limiting ring 4. The former rests on the inner ring surface of the protruding circular ring 302, which can make the operation of the motor 14 more stable and safe.

[0064] Existing technology as attached Fig. 9 As shown, if the motor needs to be horizontally limited at this time, the motor limit rod d can only be fixed to the crushing device, which is very troublesome. On the contrary, this is the outstanding practicality of the clamping ring unit 3.

[0065] A rubber filling block is provided between the limiting ring 4 and the motor 14, or the shape of the inner ring surface of the limiting ring 4 is determined by the cross-sectional shape and size of the motor 14, so as to ensure a sufficient snap-fitting and fixing effect between the two.

[0066] In addition, the limiting support rod 5 avoids the feed opening 18 in the circumferential direction, thereby ensuring the convenience of the crushing operation.

[0067] A filter screen with a frame 6 is also provided on the bottom plate discharge port 16 , and a connecting column 7 is provided between the filter screen with a frame 6 and the bottom plate discharge port 16 .

[0068] In this embodiment, a discharge pipe can be further provided on the bottom plate discharge port 16, and the connecting column 7 is provided on the bottom plate discharge port 16 or the discharge pipe for stably installing the frame filter 6, and the function of the frame filter 6 is to ensure that the crushing effect of the device is controllable and traceable. The large particles c trapped on the frame filter 6 can be re-added to the feed port 18 for full crushing. Therefore, the connecting column 7 is installed in a screw connection or a snap connection.

[0069] The frame of the framed filter screen 6 is in the shape of a ring, and the filter screen is in the shape of a circle. The gap between the frame and the bottom plate outlet 16 is the installation position of the connecting column 7 and also the extension position of the water inlet pipe 205.

[0070] The connecting column 7 is also provided with an elastic protective sleeve 8 for filter vibration for receiving the rotation impact force of the water inlet pipe 205 .

[0071] In this embodiment, the functions of the water inlet pipe 205 include at least the following three functions: First, connect the annular tube 201 and an external water pump or air pump to supply water or air to the vertical tube 202 and the perforated tube 204; Second, as a driving position for rotating the entire tubular rotating frame unit 2, manual driving or motor automatic driving is possible; Third, the elastic protective sleeve 8 for filter vibration is appropriately impacted to make the frame filter 6 vibrate, so as to further screen the large particles c and prevent the frame filter 6 from being blocked quickly and frequently.

[0072] There are two connecting columns 7, and the elastic protective sleeve 8 for filter vibration is made of ordinary rubber.

[0073] The above detailed description of the implementation methods of the present application is made in conjunction with the accompanying drawings, but the present application is not limited to the above implementation methods. Various modifications can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the present application. These are all non-creative modifications and are protected by the patent law as long as they are within the scope of the claims of the present application.
