Description
Technical Field
[0001] The utility model relates to the field of slag screens, in particular to a windproof slag screen for concrete production. Background Art
[0002] Concrete is one of the most important civil engineering materials in contemporary times. It is an artificial stone made of cementitious materials, granular aggregates, water, and admixtures and additives added in a certain proportion, which are evenly stirred, compacted into shape, and cured and hardened. Concrete often needs to be screened with a slag screen during use. In order to adapt to special construction sites, multifunctional slag screens have been developed later, such as windproof slag screens or stable slag screens.
[0003] The existing windproof debris screens used in concrete production are mostly composed of a box body, a screen plate, a vibration device and other components. When in use, workers put the sand to be screened into the body and start the vibrator. Through repeated vibrations, the sand on the surface of the screen passes through the screen holes and enters the discharge port, completing the screening of the concrete. Due to its simple structure and low production cost, it is widely purchased by major concrete manufacturers.
[0004] However, during the screening process, some concrete raw materials may be condensed into blocks due to long storage time or humid storage environment. It is difficult to screen them by vibration alone. The lumps of concrete will block the sieve holes of the screen, affecting the discharge efficiency, resulting in low overall screening efficiency, which is very inconvenient. Utility Model Content
[0005] Based on this, the purpose of the utility model is to provide a windproof slag screen for concrete production to solve the technical problems mentioned in the above background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a windproof debris screen for concrete production, comprising a support frame, a box body is fixedly installed at one end of the support frame, and a motor is fixedly installed at one end of the box body, a first reciprocating screw is fixedly connected to the output end of the motor, and a slider is sleeved on the outside of the first reciprocating screw rod, a first sieve plate is fixedly installed at one end of the slider, and a first sieve plate is provided with a first sieve hole inside, a transmission rod is movably installed inside the box body, and the first reciprocating screw rod and the transmission rod are connected by a first belt, a second sieve plate is fixedly installed inside the box body, and a second sieve hole is provided inside the second sieve plate, a movable groove for the movement of the first sieve plate is provided inside the box body, and a baffle is fixedly installed at one end of the box body, and an auxiliary device for assisting its unloading is movably installed inside the box body.
[0007] By adopting the above technical scheme, by providing components such as a box body, a first reciprocating screw rod, a slider, a baffle, a first sieve plate and a second sieve plate, when a worker uses the utility model, he can start the box body to make the first sieve plate reciprocate, simulating the worker manually moving the sieve plate to generate vibration. The moving first sieve plate can effectively ensure that the concrete raw materials will not block the first sieve holes, thereby improving the screening efficiency. At the same time, when encountering lumps of concrete raw materials, they will fall to the end face of the second sieve plate. When the first sieve plate moves, it will squeeze and crush the lumps of concrete raw materials to separate them, thereby improving its overall screening efficiency.
[0008] The utility model is further configured such that the auxiliary device includes a second belt, a second reciprocating screw, a scraper, a limit rod, a through hole and a feed port, a second reciprocating screw is movably installed inside the box, and the second reciprocating screw is connected to the transmission rod through a second belt, and a scraper is provided on the outside of the second reciprocating screw.
[0009] By adopting the above technical solution, the second belt is set up, eliminating the need to add a new power source, so that when the transmission rod rotates, the reciprocating screw rod can be driven to rotate, and the scraper can be driven to reciprocate at the same time, which can effectively ensure that the concrete raw materials will not block the through holes, ensure the feeding speed of the concrete raw materials, reduce production costs, and improve its overall screening efficiency.
[0010] The utility model is further configured that a plurality of through holes are provided inside the box body, a feed opening is fixedly installed at one end of the box body, and the feed opening is in the shape of an inverted triangle.
[0011] By adopting the above technical scheme, multiple groups of through holes can ensure the discharge speed of concrete raw materials, and cooperate with the scraper to effectively prevent the multiple groups of through holes from being blocked. The discharge port is set in an inverted triangle shape, so that the end face that falls to the small material port will slide out of the box due to gravity, and the landing point of the concrete raw materials that have completed screening can be collected to improve work efficiency.
[0012] The utility model is further configured that a limiting block is fixedly installed at one end of the sliding block, and a limiting groove matching the limiting block is opened inside the box body.
[0013] By adopting the above technical solution, the limiting block cooperates with the limiting groove to ensure that the moving direction of the slider does not change, and ensure that the slider can always drive the first screen plate to perform reciprocating motion.
[0014] The utility model is further configured that a limiting rod for limiting the scraper is fixedly installed inside the box body, and a sliding groove for the slider to move is opened inside the box body.
[0015] By adopting the above technical solution, the limit rod can limit and fix the scraper to prevent the scraper from rotating along with the second reciprocating screw, and the slide groove can provide moving space for the slider to ensure that the slider can move inside the slide groove.
[0016] The utility model is further configured such that the length of the first sieve plate is greater than that of the second sieve plate, and the diameter of the first sieve hole is greater than that of the second sieve hole.
[0017] By adopting the above technical solution, the length of the first sieve plate is greater than that of the second sieve plate, so that the first sieve plate will not leak gaps when moving, and the concrete raw materials can be continuously screened multiple times. At the same time, the diameter of the first sieve hole is greater than that of the second sieve hole. As a result, the lumps of concrete raw materials that cannot pass through the second sieve hole will remain on the end surface of the second sieve plate, and will be crushed during the movement of the first sieve plate, thereby improving the screening efficiency.
[0018] In summary, the utility model mainly has the following beneficial effects:
[0019] 1. The utility model is provided with a box body, a first reciprocating screw rod, a slider, a baffle, a first sieve plate and a second sieve plate and other components, so that when a worker uses the utility model, the box body can be started to make the first sieve plate reciprocate, simulating the worker manually moving the sieve plate to generate vibration. The moving first sieve plate can effectively ensure that the concrete raw materials will not block the first sieve holes, thereby improving the screening efficiency. At the same time, when encountering lumps of concrete raw materials, they will fall to the end face of the second sieve plate. When the first sieve plate moves, it will squeeze and crush the lumps of concrete raw materials to separate them, thereby improving its overall screening efficiency.
[0020] 2. The utility model is provided with components such as a second belt, a second reciprocating screw, a scraper and a limit rod, so that when the box is screening concrete, the second belt drives the second reciprocating screw to push the concrete principle on the inner end surface of the box, helping it to be better discharged from the inside of the box from the discharge port, effectively preventing a large amount of concrete raw materials from clogging the through hole, and improving the overall reliability and working efficiency of the equipment.

The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.
[0027] The following describes an embodiment of the utility model based on its overall structure.
[0028] A windproof slag screen for concrete production, such as Figure 1-4 As shown, it includes a support frame 1, one end of the support frame 1 is fixedly installed with a box body 2, and one end of the box body 2 is fixedly installed with a motor 3, the output end of the motor 3 is fixedly connected with a first reciprocating screw rod 4, and the outer sleeve of the first reciprocating screw rod 4 is provided with a slider 5, one end of the slider 5 is fixedly installed with a first sieve plate 10, and the first sieve plate 10 has a first sieve hole 11 opened inside, a transmission rod 15 is movably installed inside the box body 2, and the first reciprocating screw rod 4 and the transmission rod 15 are connected by a first belt 22, a second sieve plate 12 is fixedly installed inside the box body 2, and the second sieve plate 12 has a second sieve hole 11 opened inside Hole 13, a movable groove 14 for the first sieve plate 10 to move is opened inside the box body 2, and a baffle 9 is fixedly installed at one end of the box body 2, and an auxiliary device for assisting its unloading is movably installed inside the box body 2. When a worker needs to use the utility model, he must first place the concrete raw materials into the interior of the box body 2, start the motor 3 to rotate the first reciprocating screw 4, and screen the concrete raw materials. At the same time, when encountering block concrete raw materials, when the first sieve hole 11 moves, the block concrete raw materials will be squeezed and broken to complete the screening, thereby completing the screening of the concrete raw materials.
[0029] See also Figure 2 - Figure 4The auxiliary device includes a second belt 16, a second reciprocating screw rod 17, a scraper 18, a limit rod 19, a through hole 20 and a discharge port 21. The second reciprocating screw rod 17 is movably installed inside the box body 2, and the second reciprocating screw rod 17 is connected to the transmission rod 15 through the second belt 16. The scraper 18 is sleeved on the outside of the second reciprocating screw rod 17. The setting of the second belt 16 eliminates the need to add a new power source, so that when the transmission rod 15 rotates, the reciprocating screw rod 17 can be driven to rotate, and the scraper 18 can be driven to reciprocate at the same time, which can effectively ensure that the concrete raw material will not block the through hole 20, ensure the discharge speed of the concrete raw material, reduce production costs, and improve its overall screening efficiency.
[0030] See also Figure 4 A plurality of through holes 20 are provided inside the box body 2, and a discharge port 21 is fixedly installed at one end of the box body 2, and the shape of the discharge port 21 is an inverted triangle. The plurality of through holes 20 can ensure the discharge speed of the concrete raw materials, and cooperate with the scraper 18 to effectively prevent the plurality of through holes 20 from being blocked. The discharge port 21 is an inverted triangle, so that the end surface falling to the small material port 21 will slide out of the box body 2 under the influence of gravity, and the landing point of the concrete raw materials that have completed the screening can be collected to improve the work efficiency.
[0031] See also Figure 3 A limit block 7 is fixedly installed at one end of the slider 5, and a limit groove 8 matching the limit block 7 is opened inside the box body 2. The limit block 7 cooperates with the limit groove 8 to ensure that the moving direction of the slider 5 does not change, and ensures that the slider 5 can always drive the first screen plate 10 to reciprocate.
[0032] See also Figure 3 - Figure 4 A limit rod 19 for limiting the scraper 18 is fixedly installed inside the box body 2, and a slide groove 6 for the slider 5 to move is opened inside the box body 2. The limit rod 19 can limit and fix the scraper 18 to prevent the scraper 18 from rotating together with the second reciprocating screw 17. The slide groove 6 can provide moving space for the slider 5 to ensure that the slider 5 can move inside the slide groove 6.
[0033] See also Figure 3 - Figure 4 The length of the first sieve plate 10 is greater than that of the second sieve plate 12, and the diameter of the first sieve hole 11 is greater than that of the second sieve hole 13. The length of the first sieve plate 10 is greater than that of the second sieve plate 12, so that the first sieve plate 10 will not leak out of the gap when moving, and the concrete raw materials can be continuously screened multiple times. At the same time, the diameter of the first sieve hole 11 is greater than that of the second sieve hole 13. The lumps of concrete raw materials that cannot pass through the second sieve hole 13 will remain on the end surface of the second sieve plate 12, and will be crushed during the movement of the first sieve plate 10, thereby improving the screening efficiency.
[0034] The working principle of the utility model is as follows: when a worker needs to use the utility model, he needs to first place the concrete raw materials into the interior of the box body 2, and then start the motor 3 to rotate the first reciprocating screw 4, so as to drive the first screen plate 10 to reciprocate inside the box body 2 to screen the concrete raw materials. At the same time, when encountering block concrete raw materials, since the diameter of the first screen hole 11 is larger than the second screen hole 13, the block concrete raw materials can fall to the end face of the second screen plate 12 but cannot pass through the second screen hole 13. When the first screen hole 11 moves, the block concrete raw materials will be squeezed and broken to complete the screening. The screened concrete raw materials fall to the inner end face of the box body 2, and the second belt 16 can make the second reciprocating screw 17 rotate along with the transmission rod 15, so that the scraper 18 pushes the concrete raw materials from the through hole 20 into the discharge port 21 to complete the screening of the concrete raw materials.
