Description

Technical Field

[0001] This invention relates to the field of concrete mixing equipment technology, specifically to a high-efficiency and energy-saving concrete mixing plant equipment. Background Technology

[0002] A concrete batching plant is a combined unit used for centralized mixing of concrete. It has high productivity, can ensure the quality of concrete, and saves cement. Its operation involves metering the required materials through a metering hopper, then conveying them to the mixing unit via a conveying mechanism. The cement and aggregate are then thoroughly mixed and stored in a cement silo for use by mixer trucks.

[0003] In the operation of a concrete mixing plant, conveyor belts are used to transport stones, which facilitates a uniform supply when the stones are delivered to the mixing unit. However, when using existing conveyor belts, it is difficult to ensure that the stones are evenly spread on the conveyor belts, making it difficult to control the amount of stones added during mixing, resulting in longer mixing time and affecting the efficiency of concrete processing. Summary of the Invention

[0007] The screening mechanism includes a rotating plate movably connected to the surface of a conveyor belt. An arc-shaped plate is fixedly connected to one end of the rotating plate, and a rotating rod is fixedly connected to the other end of the rotating plate. A screening rod is movably connected to the side of the rotating plate. A connecting frame and a connecting plate are fixedly connected to the surface of the support frame. A collection box is attached to the upper surface of the connecting plate. A sliding groove is formed inside the connecting plate. A connecting block is fixedly connected to the lower surface of the collection box, and a sliding rod is fixedly connected to the surface of the connecting block.

[0008] Preferably, there are five sets of rotating plates and sieve rods, with two rotating plates in each set and four sieve rods in each set, and the two ends of the rotating rods are rotatably connected to the surface of the connecting frame.

[0009] Preferably, the surface size of the arc-shaped plate is the same as that of the conveyor belt, the surface size of the collection box is larger than that of the arc-shaped plate, the surface size of the sliding rod is smaller than that of the chute, and a motor is fixedly connected to the surface of the connecting frame.

[0010] Preferably, the surface of the motor's output shaft is fixedly connected to the surface of the rotating rod, the connecting block and the sliding rod are slidably connected to the surface of the slide groove, one end of the connecting plate is square, and the other end of the connecting plate is arc-shaped.

[0011] Preferably, the rotating plate is provided with an adjustment mechanism, which includes a locking block fixedly connected to the inside of the rotating plate. The rotating plate has a movable groove inside, the sieve rod has a placement groove on its surface, the locking block has a rack engaged with its surface, the rotating plate has a through groove, the rack has a screw fixedly connected to its surface, the screw has a hand-tightening nut threadedly connected to its surface, the placement groove has a connecting spring and a connecting rod fixedly connected to its surface, and the rack has a groove on its surface.

[0012] Preferably, there are two sets of the card blocks, and the two sets of card blocks are fixedly connected to the surface of the movable groove. The surface of the movable groove is T-shaped, and the surface size of the movable groove is larger than the surface size of the sieve rod.

[0013] Preferably, the surface size of the through groove is larger than the surface size of the screw, and the surface size of the hand-tightening nut is larger than the surface size of the through groove.

[0014] Preferably, the hand-tightening nut is abutted against the surface of the rotating plate, and two sets of grooves and connecting rods are provided. One end of each set of connecting rods is fixedly connected to the surface of the storage groove, and the other end of each set of connecting rods is fitted with a rotating shaft.

[0015] Preferably, the two ends of the rotating shaft are fixedly connected to the surface of the groove, the surface size of the rack is smaller than the surface size of the storage groove, and two sets of connecting springs are provided, with the two sets of connecting springs located on both sides of the storage groove.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. Through the connection between the screening rod and the rotating plate, stones unevenly distributed on the surface of the conveyor belt are scooped up by the arc plate and fall through the gaps in the screening rod during screening, so that the stones are evenly scattered on the surface of the conveyor belt. At the same time, some larger stones enter the collection box along the surface of the screening rod and are crushed again. After the stones are evenly distributed, the amount of stones entering the mixing device is continuously and stably supplied, resulting in better concrete. This avoids the increase in mixing time due to uneven mixing, making the equipment more efficient and energy-saving in processing concrete materials.

[0019] 2. By engaging different positions on the rack and pinion, stones of varying sizes can be screened according to requirements. The sieve rod is adjusted to a suitable position, and the hand-tightening nut and screw secure the sieve rod in place. At this point, the hand-tightening nut abuts against the surface of the rotating plate, preventing further rotation of the rack. Adjusting the position of the sieve rod through the adjustment mechanism removes stones that do not meet the required size, resulting in a finer final concrete product and better mixing. This avoids the need for subsequent processing of larger stones, making the process more efficient and energy-saving. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figure 1-8 One embodiment provided by the present invention:

[0031] A high-efficiency and energy-saving concrete mixing plant equipment includes:

[0032] The machine body includes a conveyor belt 1, a support frame 11 is fixedly connected to the surface of the conveyor belt 1, a mixer 13 is installed on the lower surface of the conveyor belt 1, and a hopper 12 is fixedly connected to the upper surface of the mixer 13. The material to be mixed is conveyed by the conveyor belt 1, and after reaching the end of the conveyor belt 1, the material naturally falls into the hopper 12 and then enters the mixer 13 for mixing.

[0033] The screening mechanism includes a rotating plate 2, which is movably connected to the surface of the conveyor belt 1. An arc-shaped plate 22 is fixedly connected to one end of the rotating plate 2, and a rotating rod 23 is fixedly connected to the other end of the rotating plate 2. A screening rod 21 is movably connected to the side of the rotating plate 2. A connecting frame 24 and a connecting plate 26 are fixedly connected to the surface of the support frame 11. A collection box 25 is attached to the upper surface of the connecting plate 26. A sliding groove 27 is opened inside the connecting plate 26. A connecting block 28 is fixedly connected to the lower surface of the collection box 25, and a sliding rod 29 is fixedly connected to the surface of the connecting block 28. Under the action of the collection box 25, materials that do not meet the requirements or are too large are collected in the collection box 25 to avoid mixing with other materials, reduce the need for subsequent processing of non-compliant materials, thereby reducing losses in the process and making the whole process more efficient.

[0034] Furthermore, five sets of rotating plates 2 and sieve rods 21 are provided. Each set has two rotating plates 2 and four sieve rods 21. The two ends of the rotating rods 23 are rotatably connected to the surface of the connecting frame 24. Under the action of the sieve rods 21, the material is sieved, so that when the material is placed on the surface of the conveyor belt 1, the material is evenly distributed on the surface of the conveyor belt 1, making the mixing more thorough, and thus achieving the effect of high efficiency and energy saving in the mixing process.

[0035] Furthermore, the surface size of the arc plate 22 is the same as that of the conveyor belt 1, the surface size of the collection box 25 is larger than that of the arc plate 22, the surface size of the sliding rod 29 is smaller than that of the chute 27, and a motor is fixedly connected to the surface of the connecting frame 24. Under the action of the motor, the rotating rod 23 is rotated, which in turn drives the rotating plate 2 and the arc plate 22 to rotate, so that when the material passes through the screening mechanism, the arc plate 22 can scoop up the material for screening.

[0036] Furthermore, the surface of the motor's output shaft is fixedly connected to the surface of the rotating rod 23, and the connecting block 28 and the sliding rod 29 are slidably connected to the surface of the slide groove 27. One end of the connecting plate 26 is square, and the other end of the connecting plate 26 is arc-shaped. Under the connection action of the connecting block 28 and the sliding rod 29, after a certain amount is collected in the collection box 25, the collection box 25 is pulled outward so that its connecting block 28 slides on the surface of the slide groove 27, and the material in the collection box 25 is poured out and then reinstalled.

[0037] Furthermore, the rotating plate 2 is equipped with an adjustment mechanism, which includes a locking block 3. The locking block 3 is fixedly connected to the inside of the rotating plate 2. The rotating plate 2 has a movable groove 31 inside. The surface of the screening rod 21 has a placement groove 36. The surface of the locking block 3 is engaged with a rack 32. The surface of the rotating plate 2 has a through groove 33. The surface of the rack 32 is fixedly connected with a screw 34. The surface of the screw 34 is threadedly connected with a hand-tightening nut 35. The surface of the placement groove 36 is fixedly connected with a connecting spring 38 and a connecting rod 39. The surface of the rack 32 has a groove 37. Depending on different requirements, the required material size is also different. The position of the four sets of screening rods 21 on the rotating plate 2 is adjusted to screen out materials that do not meet the size requirements.

[0038] Furthermore, two sets of locking blocks 3 are provided, and the two sets of locking blocks 3 are fixedly connected to the surface of the movable groove 31. The surface of the movable groove 31 is T-shaped, and the surface size of the movable groove 31 is larger than the surface size of the screening rod 21. Under the action of the movable groove 31, the screening rod 21 can be adjusted on the surface of the rotating plate 2 to screen materials that do not meet the requirements.

[0039] Furthermore, the surface size of the through groove 33 is larger than that of the screw 34, and the surface size of the hand-tightening nut 35 is larger than that of the through groove 33. Under the connection of the screw 34 and the hand-tightening nut 35, the engagement is completed and the rack 32 is further limited, making the engagement more secure.

[0040] Furthermore, the hand-tightened nut 35 is abutted against the surface of the rotating plate 2. Two sets of grooves 37 and connecting rods 39 are provided. One end of the two sets of connecting rods 39 is fixedly connected to the surface of the storage groove 36, and the other end of the two sets of connecting rods 39 is fitted with a rotating shaft. Under the action of the rotating shaft and the connecting rods 39, the rack 32 can rotate around the rotating shaft.

[0041] Furthermore, the two ends of the rotating shaft are fixedly connected to the surface of the groove 37. The surface size of the rack 32 is smaller than the surface size of the storage groove 36. Two sets of connecting springs 38 are provided, and the two sets of connecting springs 38 are provided on both sides of the storage groove 36. Under the action of the storage groove 36, the rack 32 can enter the storage groove 36 when the rack 32 and the locking block 3 are engaged, so that the two are engaged smoothly.

[0042] Furthermore, one end of the connecting spring 38 is fixedly connected to the surface of the storage groove 36, and the other end of the connecting spring 38 is fixedly connected to the surface of the rack 32. Under the action of the connecting spring 38, when the sieve rod 21 is adjusted, the locking block 3 and the rack 32 are more firmly engaged, and the rack 32 also achieves a springback effect.

[0043] Working principle: After the entire screening mechanism is installed on the support frame 11, when the stones pass through the rotating plate 2 via the conveyor belt 1, the motor starts and drives the rotating rod 23 to rotate, which in turn drives the rotating plate 2 and the arc plate 22 to rotate. The arc plate 22 scoops up the stones from the surface of the conveyor belt 1. After the stones are scooped up, they are screened and separated by the rotation and the screening rod 21, so that the stones fall evenly onto the surface of the conveyor belt 1, which facilitates the even supply of stone materials during mixing. At the same time, the larger stones are screened by the screening rod 21 and enter the collection box 25 along its surface. After a certain amount is collected, the collection box 25 is pulled to make it slide. When it slides to one end of the connecting plate 26, it flips along one end of the arc of the connecting plate 26 with the sliding rod 29 as the center, and pours out the stones.

[0044] When there are requirements for the size of the stones, the distance between the screening rods 21 can be adjusted to screen out stones that meet the standards. The screening rods 21 slide along the surface of the movable groove 31 to achieve engagement of the rack 32 and the locking block 3 at different positions. Under the action of the connecting spring 38, the rack 32 always abuts against the surface of the locking block 3 during movement. When it moves to the appropriate position, the hand-tightening nut 35 is threaded to the surface of the screw 34, so that the hand-tightening nut 35 abuts against the surface of the rotating plate 2 to fix the position of the screening rods 21 and prevent the screening rods 21 from moving during screening.

[0045] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.
