Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of feeding equipment, in particular to a feeder. Background Art
[0002] Sintered bricks refer to bricks made of clay, shale, coal gangue or fly ash as raw materials, which are formed and fired at high temperature for building load-bearing and non-load-bearing walls. At present, when producing and processing sintered bricks, a box feeder is usually used. As a device for uniform and quantitative feeding, the box feeder controls the feeding amount of raw materials to ensure that the raw materials are fully and evenly mixed.
[0003] However, common raw materials for sintered bricks are mixtures of clay and gravel. When stored in a box feeder, they are prone to solidify and agglomerate, affecting the subsequent discharging and shaping work of sintered bricks. It not only easily causes blockage inside the box feeder, but also hinders the normal processing and production of sintered bricks. Summary of the Utility Model
[0004] In order to overcome the shortcomings of the prior art, this application provides a feeder.
[0005] A feeder provided by this application adopts the following technical solutions:
[0006] A feeder includes a frame. A screening component for screening raw materials is arranged on the frame. The screening component includes a mounting frame. The mounting frame is arranged on the top of the frame. A screening box is arranged on the mounting frame. A plurality of screening holes are evenly formed on the bottom surface of the screening box. A roller is rotatably arranged at the bottom of the mounting frame. A limiting groove is formed on the top of the frame. The roller is rotatably arranged in the limiting groove. A driving motor is arranged on the frame. A crank is hinged to the output shaft of the driving motor. A limiting cylinder is arranged on the frame. A sliding rod is slidably arranged along the horizontal direction in the limiting cylinder. One end of the sliding rod is connected to the mounting frame, and the other end is hinged to the end of the crank far from the driving motor.

[0007] By adopting the above technical solutions, during the rotation of the driving motor, the mounting frame will be driven to move. During the movement of the mounting frame, the screening box will be driven to move synchronously. Under the action of inertia, the raw materials in the screening box will be slower than the moving speed of the screening box, so that the raw materials meeting the production requirements can fall through the screening holes onto the conveyor belt and then enter the next production step, improving the production quality of subsequent sintered bricks. The raw materials with larger particles will stay in the screening box.
[0008] Optionally, fixed seats are provided at both ends of the frame. A plurality of abutting springs are evenly arranged on the fixed seats, and impact blocks are arranged at the ends of the abutting springs far away from the fixed seats.
[0009] By adopting the above technical solution, the abutting springs can play a certain buffering role and protect the frame.
[0010] Optionally, one end of the material screening box is rotatably connected to the mounting frame through a rotating shaft, and a support block for supporting the end of the material screening box away from the rotating shaft is arranged on the mounting frame.
[0011] By adopting the above technical solution, the driving assembly drives the material screening box to rotate around the rotating shaft, so that the material screening box is tilted, facilitating the discharge of large-particle raw materials inside the material screening box to the outside of the material screening box.
[0012] Optionally, the driving assembly includes two hydraulic cylinders. The two hydraulic cylinders are respectively arranged on both sides of the material screening box. The bottom of the hydraulic cylinder is hinged to the mounting frame. An installation block is rotatably arranged on the side plate of the material screening box, and the end of the piston rod of the hydraulic cylinder away from the cylinder body is connected to the installation block.
[0013] By adopting the above technical solution, when the hydraulic cylinder is started, the piston rod of the hydraulic cylinder will extend in a direction away from the cylinder body, thereby being able to push the material screening box to rotate around the rotating shaft, and further tilting the material screening box to facilitate the discharge of large-particle raw materials inside the material screening box to the outside of the material screening box.
[0014] Optionally, the fixing assembly includes a push rod motor. The push rod motor is arranged on the top of the mounting frame. A fixing block is arranged at the end of the push rod of the push rod motor. A plug rod is arranged on the fixing block along the vertical direction, and the plug rod is inserted into the support block.
[0015] By adopting the above technical solution, the push rod of the push rod motor itself will drive the plug rod to pass through the material screening box and be inserted into the support block, so that the fixing block and the support block clamp the end of the material screening box in the middle, enabling the material screening box to work more stably.
[0016] Optionally, a buffer plate is slidably sleeved on the plug rod, and a buffer spring is also sleeved on the plug rod. One end of the buffer spring is connected to the buffer plate and the other end is connected to the fixing block.
[0017] By adopting the above technical solution, the buffer spring can buffer the vibration generated during the reciprocating movement of the mounting frame, so that the material screening box can be placed more stably on the mounting frame for work.
[0018] Optionally, a discharge port for facilitating the discharge of waste inside the material screening box is opened on the machine shell.
[0019] By adopting the above technical solution, the screening box can discharge the large-particle raw materials inside itself from the discharge port position on the casing, and the staff can also assist in cleaning or dredging the screening holes inside the screening box through the discharge port position.
[0020] Optionally, a plurality of flexible shielding plates are uniformly arranged at the bottom of the screening box.
[0021] By adopting the above technical solution, when the raw materials inside the screening box fall onto the conveyor belt, the flexible shielding plates can, to a certain extent, prevent the raw materials from splashing, enabling the raw materials to fall onto the conveyor belt better.
[0022] The utility model has the following advantages:
[0023] 1. By arranging the screening component and the driving motor, the raw materials meeting the production requirements can fall through the screening holes onto the conveyor belt and then enter the next production step, improving the production quality of the subsequent sintered bricks;
[0024] 2. By arranging the driving component, the screening box can be pushed to rotate around the rotating shaft, and then the screening box is tilted, facilitating the discharge of the large-particle raw materials inside the screening box outside the screening box;

[0031] The following further describes the present utility model in conjunction with the attached drawings, but the protection scope of the present utility model is not limited to the following description.
[0032] As Figures 1 to 4 shown, a feeder includes a frame 1, on which a screening component 2 for screening raw materials is installed. The screening component 2 includes a mounting frame 21, which is installed on the top of the frame 1. A screening box 22 is installed on the mounting frame 21. A plurality of screening holes 23 are evenly opened on the bottom surface of the screening box 22. A roller 24 is rotatably installed at the bottom of the mounting frame 21. A limiting groove 25 is opened on the top of the frame 1, and the roller 24 is rotatably installed in the limiting groove 25. A driving motor 26 is installed on the frame 1. A crank 27 is hingedly installed on the output shaft of the driving motor 26. A limiting cylinder 28 is installed on the frame 1. A slide rod 29 is slidably installed in the limiting cylinder 28 along the horizontal direction. One end of the slide rod 29 is connected to the mounting frame 21, and the other end is hingedly connected to the end of the crank 27 away from the driving motor 26. A conveyor belt 11 is installed on the top of the frame 1 along the horizontal direction, and the conveyor belt 11 is located at the bottom of the screening box 22. A housing 12 is installed on the frame 1. A feeding hopper 13 is installed on the top of the housing 12. The bottom of the feeding hopper 13 is located at the top of the screening box 22. One end of the screening box 22 is rotatably connected to the mounting frame 21. A driving component 4 for driving the screening box 22 to rotate is also installed on the mounting frame 21. A fixing component 5 for fixing the screening box 22 is also installed on the mounting frame 21; when in use, the staff pours the raw materials into the feeding hopper 13, and then the raw materials fall from the bottom of the feeding hopper 13 into the screening box 22. When there is a certain amount of raw materials in the screening box 22, start the driving motor 26. During the rotation of the driving motor 26, the crank 27 will be driven to rotate. During the rotation of the crank 27, the slide rod 29 will be driven to reciprocate in the limiting cylinder 28. The limiting cylinder 28 limits the movement of the slide rod 29. During the movement of the slide rod 29, the mounting frame 21 will be driven to reciprocate along the length direction of the limiting groove 25. The roller 24 can reduce the friction between the mounting frame 21 and the limiting groove 25, so that the mounting frame 21 can move more smoothly along the length direction of the limiting groove 25. During the movement of the mounting frame 21, the screening box 22 will be driven to move synchronously. Under the action of inertia, the raw materials in the screening box 22 will be slower than the moving speed of the screening box 22, so that the raw materials meeting the production requirements can pass through the screening holes 23 and fall onto the conveyor belt 11, and then enter the next production step. The raw materials with larger particles will stay in the screening box 22, and the staff can clean the large-particle raw materials in the screening box 22 regularly.
[0033] As Figures 1 to 4As shown in the figure, fixed seats 3 are installed at both ends of the frame 1. A plurality of abutting springs 31 are evenly installed on the fixed seats 3. An impact block 32 is installed at one end of the abutting spring 31 away from the fixed seat 3. In this embodiment, one end of each of the plurality of abutting springs 31 away from the fixed seat 3 is connected to the impact block 32. When the roller 24 at the bottom of the mounting frame 21 reciprocates along the length direction of the limiting groove 25, during the movement of the mounting frame 21, it will collide with the impact block 32. At this time, the abutting spring 31 is compressed, thus playing a certain buffering role and protecting the frame 1.
[0034] As Figures 1 to 4 shown in the figure, one end of the screening box 22 is rotatably connected to the mounting frame 21 through a rotating shaft 33. A support block 34 for supporting the end of the screening box 22 away from the rotating shaft 33 is installed on the mounting frame 21. A driving component 4 for driving the screening box 22 to rotate is also installed on the mounting frame 21. By driving the driving component 4, the screening box 22 is driven to rotate around the rotating shaft 33 as the center, so that the screening box 22 is tilted, facilitating the discharge of large-particle raw materials inside the screening box 22 to the outside of the screening box 22.
[0035] As Figures 1 to 4 shown in the figure, the driving component 4 includes two hydraulic cylinders 41. The two hydraulic cylinders 41 are respectively installed on both sides of the screening box 22. The bottom of the hydraulic cylinder 41 is hinged and installed on the mounting frame 21. A mounting block 42 is rotatably installed on the side plate of the screening box 22. One end of the piston rod of the hydraulic cylinder 41 away from the cylinder body is connected to the mounting block 42. When the hydraulic cylinder 41 is started, the piston rod of the hydraulic cylinder 41 will extend in the direction away from the cylinder body, thereby being able to push the screening box 22 to rotate around the rotating shaft 33 as the center, and then tilting the screening box 22, facilitating the discharge of large-particle raw materials inside the screening box 22 to the outside of the screening box 22, and to a certain extent preventing large-particle raw materials from blocking the sieve holes 23.
[0036] As Figures 1 to 4 shown in the figure, the fixing component 5 includes a push rod motor 51. The push rod motor 51 is installed on the top of the mounting frame 21. A fixing block 52 is installed at the end of the push rod of the push rod motor 51. A plug rod 53 is installed on the fixing block 52 along the vertical direction. The plug rod 53 is inserted into the support block 34. Since the screening box 22 is rotatably connected to the mounting frame 21 through the rotating shaft 33, when the screening box 22 screens the raw materials, due to vibration, the screening box 22 will not be stably placed on the support block 34, thus affecting the normal operation of the screening box 22. Therefore, when the end of the screening box 22 is placed on the support block 34, the push rod motor 51 is started, and the push rod of the push rod motor 51 itself will move in the direction close to the support block 34, thereby driving the plug rod 53 to pass through the screening box 22 and be inserted into the support block 34. The fixing block 52 and the support block 34 clamp the end of the screening box 22 in the middle, enabling the screening box 22 to work more stably.
[0037] As shown Figures 1 to 4 In the figure, a buffer plate 54 is sleeved on the insertion rod 53 in a sliding manner, and a buffer spring 55 is also sleeved on the insertion rod 53. One end of the buffer spring 55 is connected to the buffer plate 54, and the other end is connected to the fixed block 52. During the reciprocating movement of the mounting frame 21, vibrations will occur. When vibrating, the screening box 22 will impact the buffer plate 54, and the buffer spring 55 can buffer this part of the force, so that the screening box 22 can be placed on the mounting frame 21 more stably for work.
[0038] As shown Figures 1 to 4 In the figure, a discharge port 14 for facilitating the discharge of waste inside the screening box 22 is opened on the housing 12. When it is necessary to pour out the large-particle raw materials inside the screening box 22, the screening box 22 is rotated by the driving assembly 4, and the screening box 22 can discharge the large-particle raw materials inside itself from the position of the discharge port 14 on the housing 12. Workers can also assist in cleaning or dredging the sieve holes 23 inside the screening box 22 through the position of the discharge port 14, so that the sieve holes 23 are kept unblocked and can sieve materials better.
[0039] As shown Figures 1 to 4 In the figure, a plurality of flexible shielding plates 6 are uniformly installed at the bottom of the screening box 22. In this embodiment, the flexible shielding plates 6 are made of rubber material. When the raw materials inside the screening box 22 fall onto the conveyor belt 11, the flexible shielding plates 6 can, to a certain extent, prevent the raw materials from splashing, so that the raw materials can fall onto the conveyor belt 11 better.
[0040] The implementation principle of this embodiment is as follows: During use, workers pour raw materials into the feeding hopper 13, and then the raw materials fall from the bottom of the feeding hopper 13 into the screening box 22. When there is a certain amount of raw materials in the screening box 22, the driving motor 26 is started. During the rotation of the driving motor 26, the crank 27 will be driven to rotate. During the rotation of the crank 27, the sliding rod 29 will be driven to reciprocate inside the limiting cylinder 28. The limiting cylinder 28 limits the movement of the sliding rod 29. During the movement of the sliding rod 29, the mounting frame 21 will be driven to reciprocate along the length direction of the limiting groove 25. The roller 24 can reduce the friction between the mounting frame 21 and the limiting groove 25, so that the mounting frame 21 can reciprocate along the length direction of the limiting groove 25 more smoothly. During the movement of the mounting frame 21, the screening box 22 will be driven to move synchronously. Under the action of inertia, the raw materials in the screening box 22 will be slower than the moving speed of the screening box 22, so that the raw materials meeting the production requirements can fall through the sieve holes 23 onto the conveyor belt 11 and then enter the next production step. The raw materials with larger particles will stay in the screening box 22, and workers can clean the large-particle raw materials in the screening box 22 regularly.
[0041] The above are only the preferred embodiments of the present utility model, and do not impose any formal limitations on the present utility model. Any person skilled in the art can, without departing from the scope of the technical solution of the present utility model, make many possible changes and modifications to the technical solution of the present utility model by using the above-mentioned technical content, or modify it into equivalent embodiments with equivalent changes. Therefore, all changes, modifications, equivalent changes and modifications made to the above embodiments based on the technology of the present utility model without departing from the content of the technical solution of the present utility model shall fall within the protection scope of this technical solution.
