Abstract
Description
Technical Field
[0001] This utility model relates to the field of fine screening, coarse screening, sieving or sorting of solid materials using mesh, filter screen, grid or other similar tools, specifically an adjustable new linear screen. Background Technology
[0002] A linear vibrating screen uses the excitation force generated by a vibrating motor to make the screen body move longitudinally. The material is periodically thrown forward a distance on the screen, thus completing the screening operation. Its movement trajectory is a straight line, hence the name linear vibrating screen.
[0003] The traditional method of mounting a linear screen involves adding wooden mesh frames to both the top and bottom of the screen. The bottom wooden mesh frame supports the screen, increasing the distance between the screened materials, thus allowing for better discharge. At the same time, the upper and lower mesh frames reinforce the screen, keeping it taut. However, this method makes screen replacement inconvenient, requiring the top cover to be removed, disassembled, and then the screen replaced. Furthermore, fixing the screen to the middle of the wooden mesh frame can cause the screen to deform under constant pressure during material screening, resulting in unsatisfactory screening performance.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0035] Please see Figures 1 to 5 This utility model provides a new technical solution: an adjustable linear screen, including a housing 1, an upper cover 2 fixedly connected to the upper side of the housing 1, an elastic element 3 fixedly connected to the lower side of the housing 1, a support leg 4 fixedly connected to the lower end of the elastic element 3, a fixing block 5 fixedly connected to the lower side of the housing 1, a vibration motor assembly 6 fixedly connected to the rear side of the fixing block 5, a feed pipe 7 fixedly connected to the upper side of the upper cover 2, the feed pipe 7 extending into the interior of the housing 1, a discharge port 8 opened on the front side of the housing 1, a screen 11 installed inside the housing 1, the discharge port 8 located on the upper side of the screen 11, and an installation mechanism provided on the housing 1. The installation mechanism can quickly install the screen 11 on the housing 1 and can also adjust the tension of the screen 11. The installation mechanism includes two mounting grooves 9, several snap-fit grooves 10, several pull plates 12, two limit blocks 13, two insertion ports 14, two stop blocks 15, two fixing inserts 16, three adjusting bolts 17, and three pressure plates 18.
[0036] Furthermore, two mounting slots 9 are respectively opened on the left and right sides of the housing 1, with the front sides of the two mounting slots 9 extending into the inlet / outlet 8. The left and right sides of the screen 11 extend into the interior of the two mounting slots 9, respectively. Several snap-fit slots 10 are respectively opened on the left and right sides of the housing 1, arranged symmetrically on the left and right sides, and connected to the two mounting slots 9. Several pull plates 12 are respectively fixedly connected to the left and right sides of the screen 11, and each pull plate 12 is adapted to the snap-fit slot 10. The side of the pull plates 12 that is far apart from each other has a groove to facilitate the pull plates 12 being removed from the inside of the snap-fit slot 10. Two limiting blocks 13 are respectively fixedly connected to the left and right sides of the housing 1. All three are located on the lower side of the snap-fit groove 10. Two insertion ports 14 are respectively opened on the two limiting blocks 13. Two stop blocks 15 are respectively installed on the upper side of the two limiting blocks 13. The two stop blocks 15 respectively block the mounting grooves 9 and snap-fit grooves 10 on the left and right sides. Two fixing blocks 16 are respectively fixedly connected to the lower side of the two stop blocks 15. The lower side of the two fixing blocks 16 is respectively inserted into the interior of the two insertion ports 14. Three adjusting bolts 17 are all located on the upper side of the upper cover 2. The lower end of the three adjusting bolts 17 is threaded through the upper cover 2. The number of adjusting bolts 17 changes with the length of the linear screen. Three pressure plates 18 are respectively fixedly connected to the lower end of the three adjusting bolts 17. The three pressure plates 18 are all located on the upper side of the screen 11.
[0037] Furthermore, a discharge hopper 19 is fixedly connected to the lower side of the shell 1. The discharge hopper 19 is connected to the interior of the shell 1 and is located at the front. A bottom plate 20 is fixedly connected to the interior of the shell 1. The bottom plate 20 is an L-shaped block and is located behind the discharge hopper 19. Several partitions 21 are fixedly connected to the lower side of the bottom plate 20. The lower sides of the partitions 21 are all fixedly connected to the bottom wall of the shell 1. The partitions 21 are arranged in a front-to-back arrangement, and bouncing balls 22 are provided between the partitions 21.
[0038] When starting work, if the screen 11 needs to be replaced, it must first be disassembled. First, pull the two stops 15 upwards. The two stops 15 will move the two fixing blocks 16 upwards, and then the two fixing blocks 16 will be removed from the inside of the two sockets 14. After that, the two stops 15 will no longer obstruct the mounting grooves 9 and snap-fit grooves 10 on the left and right sides. Then, turn the adjusting bolt 17, and the adjusting bolt 17 will start to move upwards. The adjusting bolt 17 will move the pressure plate 18 upwards, and then the pressure plate 18 will no longer press the screen 11 downwards. As a result, the tension of the screen 11 will become loose, and then the pull plates 12 on the left and right sides can be moved to the side that is further away from each other. The pull plates 12 on the left and right sides can be removed from the inside of the snap-fit groove 10. After removing them, pull the snap-fit groove 10 and the screen 11 forward to remove the snap-fit groove. 10 and screen 11 are removed from the inside of housing 1 for replacement. Installation can be completed in the manner described above. After installation, the two stops 15 will block the mounting groove 9 and the snap-fit groove 10, preventing the screened material from falling from the left and right sides of housing 1. At the same time, because the fixed insert 16 is long, the force generated by vibration will not shake the fixed insert 16 out of the insertion port 14. Then, rotate the adjusting bolt 17 to drive the pressure plate 18 to move downward, thereby making the screen 11 tighter. In this way, the tension of the screen 11 can be changed by adjusting the screw depth of the adjusting bolt 17, increasing the service life of the screen 11. The screen tightening method of the screen machine is changed, and the screen installation method of the screen machine is also changed. The screen 11 can be disassembled and installed without removing the top cover 2, which facilitates the replacement of the screen 11.
[0039] During screening, the vibration motor assembly 6 is activated, transmitting vibration to the fixed block 5 and the housing 1. Then, material is added through the feed pipe 7, and the material falls onto the screen 11. The vibration force then screens the material, with smaller materials falling onto the bottom plate 20 and finally moving to the discharge hopper 19 for discharge. Larger materials move forward on the screen 11 and are finally discharged through the discharge port 8. At the same time, the vibration force drives the bouncing ball 22 to bounce, which in turn causes the bouncing ball 22 to bounce and impact, improving the screening efficiency.
[0040] Working principle: When starting work, if the screen 11 needs to be replaced, it must first be disassembled. First, pull the two stops 15 upwards. The two stops 15 drive the two fixed blocks 16 upwards, and then the two fixed blocks 16 are removed from the inside of the two sockets 14. After that, the two stops 15 no longer obstruct the mounting grooves 9 and snap-fit grooves 10 on the left and right sides. Then, turn the adjusting bolt 17, and the adjusting bolt 17 begins to move upwards. The adjusting bolt 17 drives the pressure plate 18 upwards, and then the pressure plate 18 no longer presses the screen 11 downwards. As a result, the tension of the screen 11 becomes loose, and the left and right pullers can then move to the side that is further apart. Plate 12 and the pull plates 12 on the left and right sides can be removed from the inside of the snap-fit groove 10. After removal, pull the snap-fit groove 10 and screen 11 forward to remove them from the inside of the housing 1 for replacement. Installation can be completed in the above manner. After installation, the two stops 15 will block the mounting groove 9 and the snap-fit groove 10 to prevent the screened material from falling from the left and right sides of the housing 1. At the same time, because the fixed insert 16 is long, the force generated by vibration will not shake the fixed insert 16 out of the insert 14. Then, rotate the adjusting bolt 17 to drive the pressure plate 18 to move downward, thereby making the screen 11 taut.
[0041] During screening, the vibration motor assembly 6 is activated, transmitting vibration to the fixed block 5 and the housing 1. Then, material is added through the feed pipe 7, and the material falls onto the screen 11. The vibration force then screens the material, with smaller materials falling onto the bottom plate 20 and finally moving to the discharge hopper 19 for discharge. Larger materials move forward on the screen 11 and are finally discharged through the discharge port 8. At the same time, the vibration force drives the bouncing ball 22 to bounce, which in turn causes the bouncing ball 22 to bounce and impact, improving the screening efficiency.
[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
