Description

Technical Field

[0001] This application relates to the technical field of feed cylinder primary cleaning screens, and in particular to a high-efficiency feed cylinder primary cleaning screen for removing impurities. Background Technology

[0002] In the feed processing process, the removal of impurities is a key step in ensuring feed quality. Currently, there are various feed screening equipment on the market, which play an important role in the feed production process. Conventional technical means mainly include vibrating screens and rotary screens. These screening devices use vibration or rotation to screen the feed on the screen, thereby removing impurities.

[0003] Chinese Patent CN207709385U discloses a livestock feed impurity removal device, relating to the field of livestock breeding technology. This livestock feed impurity removal device includes a base, with axles fixedly installed on both sides of the base bottom, and wheels movably connected between the two axles. Through the cooperation of columns, bearing bodies, rotating rods, rotating drums, fixed blocks, screening cylinders, partitions, a motor, a first pulley, a second pulley, a belt, and a waste collection box, the rotating drum drives the screening cylinder to rotate at high speed between the two columns.

[0004] Regarding the aforementioned technologies, the inventors discovered that existing feed impurity removal devices are prone to clogging during use, affecting the normal use of feed. Furthermore, the screens of traditional feed impurity removal devices have uniform mesh openings, making it impossible to achieve graded processing and resulting in poor processing effects. Utility Model Content

[0005] In order to avoid clogging of the impurity removal device and improve the efficiency of impurity removal, this application provides a feed cylinder primary cleaning screen with high efficiency in removing impurities.

[0006] The high-efficiency feed drum primary cleaning screen provided in this application adopts the following technical solution:

[0007] A high-efficiency feed cylindrical primary cleaning screen for removing impurities includes a processing box assembly. The processing box assembly includes a main box shell, a feed shell, and a discharge shell. The feed shell and the discharge shell are respectively located at both ends of the main box shell and are fixedly connected to the main box shell. A detachable top cover assembly is installed on the upper end of the main box shell. A screen cylinder is rotatably installed on the lower end of the top cover assembly, and a drive motor for driving the screen cylinder to rotate is also fixedly installed on the top cover assembly. A cleaning component corresponding to the screen cylinder is installed on the side of the main box shell.

[0008] By adopting the above technical solution, the structure of the processing box assembly is designed to ensure that the main box shell serves as the overall processing body during use. Feed and discharge shells are installed on both sides, allowing raw materials to be fed in through the feed shell and stably discharged through the discharge shell. A detachable top cover assembly is installed on the upper surface of the main box shell, allowing the screen cylinder to be installed. During installation, the screen cylinder is first installed on the top cover assembly, and then the top cover assembly is installed on the main box shell, ensuring the screen cylinder is stably placed within the main box shell. The drive motor ensures stable operation of the screen cylinder during screening, guaranteeing that impurities in the raw materials are consistently screened to the lower end. Cleaning components corresponding to the screen cylinder are installed on the side of the main box shell, allowing for real-time cleaning of the screen mesh during the screening process, effectively preventing clogging.

[0009] Optionally, an impurity outlet shell is installed on the lower end face of the main housing, the impurity outlet shell is fixedly connected to the main housing, the side of the main housing is also provided with a positioning groove for the installation of the cleaning components, and several support feet are fixedly installed at the lower end of the main housing.

[0010] By adopting the above technical solution, and by installing an impurity outlet shell on the lower end face of the main housing, it is possible to stably collect the impurities processed in the screen cylinder during use, and then stably discharge them from the lower end through the impurity outlet shell. At the same time, by providing a positioning groove for the installation of cleaning components on the side of the main housing, it is possible to ensure that the cleaning components installed externally can perform cleaning operations on the internal screen cylinder. Furthermore, by fixing support feet at the lower end of the main housing, it is possible to ensure that the entire equipment can be stably placed on the ground for use.

[0011] Optionally, the top cover assembly includes a main cover shell and a maintenance plate, wherein the maintenance plate is installed on one side of the upper end face of the main cover shell and is fixedly connected to the main cover shell.

[0012] By adopting the above technical solution, the structure of the top cover assembly is designed to ensure that the upper part of the main body can be covered by the main cover shell during use. At the same time, by installing an inspection plate on the main cover shell, the inspection plate can be removed for observation when the interior needs to be observed, which is very convenient to use.

[0013] Optionally, the screen cylinder includes a connecting rod and a cylinder body with openings at both ends. The connecting rod is installed at both ends of the cylinder body and is fixedly connected to the cylinder body.

[0014] By adopting the above technical solution, the structure of the screen cylinder is designed to ensure that the cylinder can be positioned and installed using the connecting rods at both ends during installation. This ensures that the screen cylinder can be positioned and installed at a certain tilt angle. In this way, during the screening process, the rotation of the cylinder can ensure that the raw material flows automatically from one end, thereby achieving stable screening operation. Furthermore, by setting both ends of the cylinder to be open structures, it is convenient to fill the material from one end during use, while the screened raw material is stably discharged from the other side.

[0015] Optionally, a plurality of screen holes are evenly provided on the cylinder, and the diameter of the screen holes decreases sequentially from the feed shell to the discharge shell.

[0016] By adopting the above technical solution, and by opening several screen holes of different apertures on the cylinder, after the raw material enters the cylinder, larger impurities can first be discharged through the large apertures, and then smaller impurities can be discharged in sequence. This achieves graded discharge and eliminates the need for multiple sets of screens with different apertures for screening. It can improve screening efficiency through graded screening, and the structure is simple and compact, without increasing the overall size of the equipment.

[0017] Optionally, the lower end face of the main cover is provided with a positioning vertical plate for mounting the connecting rod, and the head of the positioning vertical plate is fixedly connected to the main cover.

[0018] By adopting the above technical solution, a positioning vertical plate is fixedly installed on the lower end face of the main cover. When it is easy to use, the connecting rod can be installed through the positioning vertical plate, ensuring that the middle part of the connecting rod can be rotatably connected with the positioning vertical plate. This makes it easier to drive the motor to drive the screen cylinder to rotate.

[0019] Optionally, the cleaning assembly includes a mounting bracket, a cleaning bracket, and a tension spring. The mounting bracket is fixedly installed on the outer side of the main housing, the cleaning bracket is slidably installed on the mounting bracket, and the head of the cleaning bracket passes through the positioning groove and contacts the outer side of the cylinder. The tension spring is fixedly installed between the mounting bracket and the cleaning bracket.

[0020] By adopting the above technical solution, the structure of the cleaning component is designed to ensure that the cleaning frame can be installed using the mounting bracket during use. This ensures that one end of the cleaning frame can be supported on the outer surface of the screen cylinder for stable cleaning. The tension spring ensures that the cleaning frame and the screen cylinder can fit stably, and even if the cleaning frame is worn, a good fit can still be maintained, thus ensuring better cleaning performance.

[0021] Optionally, the cleaning frame includes a cleaning plate, a positioning slide rod, and a connecting bend plate. One side of the cleaning plate is set as an arc surface, and several hard bristles are evenly arranged on the arc surface. The positioning slide rod and the connecting bend plate are both fixedly installed on the other side of the cleaning plate, and the positioning slide rod and the connecting bend plate are slidably connected to the mounting frame.

[0022] By adopting the above technical solution, the structure of the cleaning frame is designed to ensure that the cleaning plate can be installed on the mounting frame via the positioning slide rod and connecting bent plate during use, and can be stably slid and adjusted on the mounting frame. At the same time, one side of the cleaning plate is set as an arc surface, which makes it easier for the hard bristles set on the arc surface to stably adhere to the cylinder for cleaning operations.

[0023] In summary, this application includes at least one of the following beneficial technical effects: By installing a detachable top cover assembly on the upper end of the processing box assembly and mounting the screen cylinder on the top cover assembly, the screen cylinder can be directly removed through the top cover assembly when maintenance is required, making it easier to disassemble, assemble, and maintain.

A detachable top cover assembly 2 is installed on the upper end of the main box shell 11. A screen cylinder 3 is rotatably installed on the lower end of the top cover assembly 2, and a drive motor 4 for driving the screen cylinder 3 to rotate is also fixedly installed on the top cover assembly 2. A cleaning component 5 corresponding to the screen cylinder 3 is installed on the side of the main box shell 11. The structure of the processing box assembly 1 is designed to ensure that the main box shell 11 serves as the main processing unit during use. A feed shell 12 and a discharge shell 13 are installed on both sides, allowing raw materials to be fed in through the feed shell 12 and discharged stably through the discharge shell 13. A detachable top cover assembly 2 is installed on the upper surface of the main box shell 11, allowing the screen cylinder 3 to be installed. During installation, the screen cylinder 3 is first installed on the top cover assembly 2, and then the top cover assembly 2 is installed on the main box shell 11, ensuring the screen cylinder 3 is stably placed within the main box shell 11. The drive motor 4 ensures stable operation of the screen cylinder 3 during screening, ensuring impurities in the raw materials are consistently screened to the lower end. A cleaning component 5, corresponding to the screen cylinder 3, is installed on the side of the main box shell 11. During the screening process, the cleaning component 5 cleans the mesh of the screen cylinder 3 in real time, effectively preventing clogging.

[0034] Reference Figure 2 and Figure 3As shown, an impurity outlet shell 111 is installed on the lower end face of the main housing 11. The impurity outlet shell 111 is fixedly connected to the main housing 11. A positioning groove 112 for the installation of the cleaning assembly 5 is also provided on the side of the main housing 11, and several support feet 113 are fixedly installed at the lower end of the main housing 11. By installing the impurity outlet shell 111 on the lower end face of the main housing 11, it is possible to stably collect the impurities processed in the screen cylinder 3 during use, and then stably discharge them from the lower end through the impurity outlet shell 111. At the same time, by providing a positioning groove 112 for the installation of the cleaning assembly 5 on the side of the main housing 11, it is possible to ensure that the externally installed cleaning assembly 5 can perform cleaning operations on the internal screen cylinder 3. Furthermore, by fixing the support feet 113 at the lower end of the main housing 11, it is possible to ensure that the entire equipment can be stably placed on the ground for use.

[0035] Reference Figure 2 As shown, the top cover assembly 2 includes a main cover shell 21 and an inspection plate 22. The inspection plate 22 is installed on one side of the upper surface of the main cover shell 21 and is fixedly connected to the main cover shell 21.

At the same time, by installing the inspection plate 22 on the main cover shell 21, the inspection plate 22 can be removed for observation when the interior needs to be inspected, making it very convenient to use.

[0036] Reference Figure 1 and Figure 2As shown, the screen cylinder 3 includes a connecting rod 31 and a cylinder 32 with openings at both ends. The connecting rod 31 is installed at both ends of the cylinder 32 and is fixedly connected to the cylinder 32. The structure of the screen cylinder 3 ensures that the cylinder 32 can be positioned and installed using the connecting rods 31 at both ends, allowing the screen cylinder 3 to be positioned at a certain angle. This ensures that during screening, the rotation of the cylinder 32 allows the raw material to flow automatically from one end, achieving stable screening operations. By making both ends of the cylinder 32 open, it is convenient to fill the material from one end and stably discharge the screened raw material from the other side. The cylinder 32 has a plurality of screen holes 321 evenly distributed on it, with the diameter of the screen holes 321 decreasing sequentially from the feed shell 12 to the discharge shell 13. By opening several screen holes 321 of different apertures on the cylinder 32, after the raw material enters the cylinder 32, larger impurities can first be discharged through the larger aperture screen holes, and then smaller impurities can be discharged sequentially. This achieves graded discharge and eliminates the need for multiple sets of screens with different apertures for screening. It can improve screening efficiency through graded screening, and the structure is simple and compact, without increasing the overall size of the equipment. The lower end face of the main cover 21 is provided with a positioning vertical plate 211 for mounting the connecting rod 31. The head of the positioning vertical plate 211 is fixedly connected to the main cover 21. By fixing the positioning vertical plate 211 to the lower end face of the main cover 21, the connecting rod 31 can be installed through the positioning vertical plate 211 for easy use. This ensures that the middle part of the connecting rod 31 can be rotatably connected to the positioning vertical plate 211, which facilitates the drive motor 4 to drive the screen cylinder 3 to rotate.

[0038] Reference Figure 4 , Figure 5 and Figure 6As shown, a high-efficiency feed cylindrical primary cleaning screen for removing impurities includes a processing box assembly 1. The processing box assembly 1 includes a main box shell 11, a feed shell 12, and a discharge shell 13. The feed shell 12 and the discharge shell 13 are respectively located at both ends of the main box shell 11, and both the feed shell 12 and the discharge shell 13 are fixedly connected to the main box shell 11. A detachable top cover assembly 2 is installed on the upper end of the main box shell 11, and a screen cylinder 3 is rotatably installed on the lower end of the top cover assembly 2. A cleaning assembly 5 corresponding to the screen cylinder 3 is installed on the side of the main box shell 11. The cleaning assembly 5 includes a mounting frame 51, a cleaning frame 52, and a tension spring 53. The mounting frame 51 is fixedly installed on the outer side of the main box shell 11, and the cleaning frame 52 is slidably installed on the mounting frame 51. The head of the cleaning frame 52 passes through the positioning groove 112 and contacts the outer side of the cylinder 32. The tension spring 53 is fixedly installed between the mounting frame 51 and the cleaning frame 52. The structure of the cleaning component 5 is designed to ensure that the cleaning frame 52 can be installed using the mounting bracket 51 during use. This ensures that one end of the cleaning frame 52 can be supported on the outer surface of the screen cylinder 3 for stable cleaning. The tension spring 53 ensures that the cleaning frame 52 and the screen cylinder 3 can fit together stably. Even if the cleaning frame 52 is worn, a good fit can still be maintained, thus ensuring better cleaning performance.

[0039] Reference Figure 5 and Figure 6 As shown, the cleaning frame 52 includes a cleaning plate 521, a positioning slide rod 522, and a connecting bend plate 523. One side of the cleaning plate 521 is set as an arc surface, and a number of hard bristles 524 are evenly arranged on the arc surface.

The structural design of the cleaning frame 52 ensures that the cleaning plate 521 can be installed on the mounting frame 51 through the positioning slide rod 522 and the connecting bend plate 523 during use, and can be stably slidably adjusted on the mounting frame 51. At the same time, setting one side of the cleaning plate 521 as an arc surface makes it easier for the hard bristles 524 on the arc surface to stably adhere to the cylinder 32 for cleaning operations.

[0040] The implementation principle of the high-efficiency feed cylinder primary cleaning screen according to the embodiments of this application is as follows: During actual processing, the raw material to be processed is fed into the feed shell 12. The raw material can flow into the screen cylinder 3 along the feed shell 12. The screen cylinder 3 rotates stably under the drive of the drive motor 4, thereby driving the screen cylinder 3 to perform screening operations. This ensures that large particles of impurities first pass through the screen mesh 321 of the screen cylinder 3 and fall to the lower end, and then small particles fall in sequence. Finally, the screened raw material can be stably discharged to the outside from the discharge shell 13.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
