Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, and particularly relates to a sieving device with a crushing function. Background Technique

[0002] A sieving device screens materials of a specified particle size through a sieve mesh. Fine-grained materials smaller than the sieve mesh aperture can pass through the sieve mesh, while coarse-grained materials larger than the sieve mesh aperture will remain on the sieve mesh, thus completing the process of separating coarse and fine materials. In fields such as pharmaceuticals, grains, and fertilizers, it is necessary to screen materials. By selecting finer materials, the use value and processing effect of the materials can be improved.

[0003] At present, traditional sieving devices use an internal filter plate to filter materials. A vibrator generates vibration to accelerate the screening speed of the materials. The larger materials filtered out still need to be taken out separately and put into a crusher for re-crushing and then sieving, which increases the processes and time required for pre-processing the materials before processing, reduces the efficiency of using the materials for production, and its overall practical performance is not ideal. Therefore, a device that directly crushes larger sieved materials inside is needed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a sieving device with a crushing function to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A sieving device with a crushing function, including: a device main body, a crushing structure, and a conveying structure; a filter plate is welded to the inner wall of the device main body; the crushing structure is arranged on the inner wall of the device main body, and the device main body includes a crushing chamber welded to the inner wall of the device main body, a feeding pipe welded to the top of the crushing chamber, and a crushing roller shaft rotatably connected to the inner wall of the crushing chamber; the conveying structure is arranged on the outer wall of the device main body, and the conveying structure includes a conveying pipe arranged on the outer wall of the device main body, a feeding port opened on the outer wall of the conveying pipe, a discharging port opened on the outer wall of the conveying pipe, and a first spiral shaft rotatably connected to the inside of the conveying pipe.

[0006] By adopting the above technical solution, after the materials are sieved by the filter plate, the larger materials will remain above and gather at the feeding port. Driven by the rotating first spiral shaft, they are lifted in the conveying pipe and discharged from the discharging port into the feeding pipe, and then fall from the top of the crushing chamber between the crushing roller shafts for crushing. The crushed materials are then sieved by the filter plate. If there are still larger materials, they can be circulated for conveying and crushing. This device can reduce the time required for pre-processing the materials to make them finer, improve the overall sieving effect of the materials and the efficiency of subsequent processing, and improve the overall practicality of the device.

[0007] Preferably, the crushing structure further includes a gear welded to one end of the crushing roller shaft, a fixing frame welded to the outer wall of the device main body, and a first motor provided on the fixing frame. The rotating shaft of the first motor is connected to one end of the crushing roller shaft. There are two groups of crushing roller shafts, and the gears at one end are meshed with each other.

[0008] By adopting the above technical solution, by driving one group of crushing roller shafts to rotate with the first motor, under the transmission of the meshed gears, the two groups of crushing roller shafts can rotate towards each other. When the material falls in the middle, it can be quickly crushed by the crushing roller shafts rotating towards each other, so as to perform secondary crushing on the sieved material, thereby improving the use effect of the sieved material.

[0009] Preferably, the conveying structure further includes a second motor provided on one side of the support feet of the device main body. The rotating shaft of the second motor is connected to the bottom end of the first spiral shaft.

[0010] By adopting the above technical solution, the second motor can drive the first spiral shaft to rotate, and the larger sieved material can be vertically conveyed into the crushing structure for crushing, so as to realize the function of transferring and crushing the material and ensure the normal feeding operation of the crushing structure.

[0011] Preferably, a discharging structure is provided at the bottom of the device main body. The discharging structure includes a discharging pipe welded to the bottom of the device main body, a second spiral shaft rotatably connected inside the discharging pipe, a first bevel gear welded to the rotating rod at the bottom end of the first spiral shaft, and a second bevel gear welded to the rotating rod at one end of the second spiral shaft. The first bevel gear and the second bevel gear are meshed with each other.

[0012] By adopting the above technical solution, by installing a first bevel gear on the first spiral shaft, the second spiral shaft equipped with a second bevel gear can be driven to rotate, and the sieved material falling down can be conveyed outwards to achieve the discharging function. The device uses the same power source to start through the linkage structure, which not only increases the discharging function, but also improves the utilization rate of the power source and reduces the power cost of processing.

[0013] Preferably, a vibrator is connected to the middle position of the lower surface of the filter plate by bolts. The filter plate is in an inclined state, and the end of the filter plate close to the feed port is at a lower position.

[0014] By adopting the above technical solution, by installing a vibrator at the bottom of the inclined filter plate, the vibrator can be used to generate vibration to cause intense vibration on the surface of the filter plate. When the material falls on the upper part, the sieving rate of the filter plate for the material can be improved, and then the overall sieving efficiency of the device can be improved.

[0015] Preferably, a hopper is welded to the top of the device main body, and the bottom of the hopper is directly above the high section of the inclined filter plate.

[0016] By adopting the above technical solution, a hopper is installed above the inclined high point of the filter plate. After the material is added, it first falls to the high point of the filter plate and rolls towards the bottom for filtration along with the vibration. During the rolling process, the filtering effect of the material can be improved.

[0017] Preferably, the feeding pipe is in a horn shape and is located at the top of the crushing chamber. The end of the feeding pipe communicating with the crushing chamber is directly above the gap between two groups of crushing roller shafts.

[0018] By adopting the above technical solution, through the design of the rotating feeding pipe in a horn shape, when the material is discharged from the discharge port into the feeding pipe, the material will disperse along the feeding pipe in the horn to expand the range of entering the crushing chamber, so that the material can be evenly dispersed into the gap between the crushing roller shafts for crushing, improving the crushing effect and uniformity of the material after being crushed.

[0019] Preferably, the discharge pipe is located at the middle position of the bottom of the device main body, and the bottom of the device main body is in a symmetric slope shape and converges to the discharge pipe.

[0020] By adopting the above technical solution, through the design of the slope at the bottom of the device main body, the sieved material on the filter plate can fall along the slope and be concentrated into the middle discharge pipe, which is convenient for the second spiral shaft to rotate and convey the material out of the device. While facilitating the collection and processing of the material, it also avoids the problem of docking and adhesion of the material at the bottom of the device main body.

[0021] Compared with the prior art, the beneficial effects of the present utility model are:

[0022] (1) After the material is sieved by the filter plate, the larger materials will remain on the upper part and gather at the feeding port. Driven by the rotating first spiral shaft, they are lifted in the conveying pipe and discharged from the discharge port into the feeding pipe, falling from the top of the crushing chamber between the crushing roller shafts for crushing. The crushed material is then sieved by the filter plate again. The larger materials can be recycled for conveying and crushing. This device can reduce the time for fine treatment of the material before processing, improve the overall sieving effect of the material and the efficiency of subsequent processing, and improve the overall practicality of the device;

[0023] (2) By installing a first bevel gear on the first spiral shaft, the second spiral shaft installed with a second bevel gear can be driven to rotate, so as to convey the sieved and fallen material outwards to achieve the discharging function. By adopting a linkage structure, this device is started with the same power source, which not only increases the discharging function, but also improves the utilization rate of the power source and reduces the power cost of processing.

Driven by the rotating first spiral shaft 504, they are lifted in the conveying pipe 501 and discharged into the crushing structure 2 for crushing treatment. This device can reduce the time for fine treatment of materials before processing, improve the overall sieving effect of materials and the efficiency of subsequent processing, and improve the overall practicality of the device.

[0034] Embodiment Two

[0035] Please refer to Figures 2 to 5, the crushing structure 2 further includes a gear 204 welded to one end of the crushing roller shaft 203, a fixing bracket 205 welded to the outer wall of the device main body 1, and a first motor 206 arranged on the fixing bracket 205. The rotating shaft of the first motor 206 is connected to one end of the crushing roller shaft 203. There are two groups of crushing roller shafts 203, and the gears 204 at one end are meshed with each other. By driving one group of crushing roller shafts 203 to rotate by the first motor 206, under the transmission of the meshed gears 204, the two groups of crushing roller shafts 203 can rotate towards each other. When the material falls to the middle, it can be quickly crushed by the crushing roller shafts 203 rotating towards each other, so as to perform secondary crushing on the sieved material, thereby improving the use effect of the sieved material. The conveying structure 5 further includes a second motor 505 arranged on one side of the support feet of the device main body 1. The rotating shaft of the second motor 505 is connected to the bottom end of the first spiral shaft 504. By the second motor 505, the first spiral shaft 504 can be driven to rotate, and the larger sieved material can be vertically conveyed into the crushing structure 2 for crushing, so as to realize the function of transferring and crushing the material and ensure the normal feeding operation of the crushing structure 2.

By installing the first bevel gear 603 on the first spiral shaft 504, the second spiral shaft 602 installed with the second bevel gear 604 can be driven to rotate, and the material falling after sieving can be conveyed outwards to achieve the discharging function. This device is started by using the same power source through the linkage structure, which not only increases the discharging function, but also improves the utilization rate of the power source and reduces the power cost of processing.

[0036] Embodiment III

[0037] Please refer to Figures 1 to 5, a vibrator 4 is bolted to the middle position of the lower surface of the filter plate 3. The filter plate 3 is in an inclined state, and the end of the filter plate 3 close to the feed inlet 502 is at a lower position. By installing the vibrator 4 at the bottom of the inclined filter plate 3, the violent vibration can be generated on the surface of the filter plate 3 by the vibration generated by the vibrator 4. When the material falls on the upper part, the screening rate of the material on the filter plate 3 can be increased, and then the overall screening efficiency of the device can be improved. A hopper 7 is welded to the top of the device main body 1, and the bottom of the hopper 7 is directly above the high position of the inclined section of the filter plate 3. By installing the hopper 7 above the high point of the inclined filter plate 3, the material first falls on the high point of the filter plate 3 after being added. As it rolls towards the lower part with vibration for filtration, the filtration effect of the material can be improved during the rolling process. The feeding pipe 202 is in a horn shape and is located at the top of the crushing chamber 201. The end of the feeding pipe 202 connected to the crushing chamber 201 is directly above the gap between the two crushing roller shafts 203. Through the design of the feeding pipe 202 with a horn shape in rotation, when the material is discharged from the discharge port 503 into the feeding pipe 202, the material will be dispersed along the feeding pipe 202 in the horn to expand the range of entering the crushing chamber 201, so that the material can be evenly dispersed into the gap between the crushing roller shafts 203 for crushing, and the effect and uniformity of the material after being crushed can be improved. The discharge pipe 601 is located at the middle position of the bottom of the device main body 1, and the bottom of the device main body 1 is in a symmetric slope shape and converges to the discharge pipe 601. Through the design of the slope at the bottom of the device main body 1, the screened material on the filter plate 3 can fall along the slope and be concentrated into the middle discharge pipe 601, which is convenient for the second spiral shaft 602 to rotate and convey the material out of the device. While facilitating the collection and processing of the material, it also avoids the problem of butt adhesion of the material at the bottom of the device main body 1.

[0038] Working principle: During use, first, the material added from the hopper 7 will fall on the upper surface of the high point of the filter plate 3 and roll and be screened towards the lower part of the filter plate 3 under the vibration of the vibrator 4. The smaller material passes through the filter plate 3 and falls to the bottom of the device main body 1, and the larger material rolls to the feed inlet 502 and is lifted to the discharge port 503 by the first spiral shaft 504 driven by the second motor 505. As a result of the butt joint, the larger material enters the feeding pipe 202, slides into the crushing chamber 201 and is crushed by the crushing roller shafts 203 rotating towards each other, and finally falls onto the filter plate 3 along the inclined plate at the bottom of the crushing chamber 201 for re-screening. The second spiral shaft 602 at the bottom rotates under the meshing transmission of the first helical gear 603 and the second helical gear 604, and can discharge the screened material out of the device from the discharge pipe 601.

[0039] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention.
