Description

Technical Field

[0001] This application relates to the field of concrete production, and in particular to a concrete aggregate proportioning device and its use method. Background Art

[0002] Asphalt concrete is commonly known as asphalt concrete. Mineral materials with a certain gradation composition are artificially selected, such as crushed stones or crushed gravel, stone chips or sand, mineral powder, etc.; mixed with a certain proportion of road asphalt materials and prepared under strictly controlled conditions. According to the different binders used, it can be divided into two major categories: petroleum asphalt and coal asphalt; in some countries or regions, natural asphalt is also used or incorporated for mixing. According to the different types of aggregates used, it can be divided into several categories such as crushed stone, gravel, sandy, and slag, with crushed stone being the most commonly used.

[0003] In the related art, a Chinese patent with the authorization announcement number CN220696465U discloses an asphalt concrete aggregate proportioning device, including a mixing tank, a proportioning tank, a feeding control mechanism, a proportioning mechanism, and a mixing mechanism. A proportioning tank is fixedly connected and communicated with one side of the mixing tank by bolts. The feeding control mechanism includes a rotating block, a feeding groove, a first rotating shaft, and a first motor. A rotating block is rotatably arranged above the proportioning tank. The rotating block is circumferentially provided with a feeding groove. The front and middle of the rotating block are fixedly provided with a first rotating shaft. A first motor is fixedly arranged on the front side of the proportioning tank. The output end of the first motor is drivingly connected to the first rotating shaft. A proportioning mechanism is arranged in the proportioning tank, and a mixing mechanism is arranged in the mixing tank. In the present invention, the first motor drives the rotating block to rotate, so that the aggregates enter the feeding groove in sequence, and the weight of the aggregates entering the proportioning tank each time is kept consistent, solving the problem that excessive aggregates are likely to enter the batching pipe during pouring. The second motor drives the gear to rotate and engage with the rack to drive the arc rod and the rotating plate to rotate and fit the proportioning tank, facilitating the aggregates to slide down from the electronic scale fully and avoiding residue.

[0004] When there are many types of aggregates to be proportioned, the setting of the rotating block can only ensure the quantitative addition of one type of aggregate to the proportioning tank. Until the quantity of one type of aggregate reaches the standard, then the second type of aggregate is added to the proportioning tank through the rotating block for quantitative proportioning, and the above steps are repeated until the proportioning of all types of aggregates in the proportioning tank is completed. This process is cumbersome, resulting in a low proportioning efficiency, so it needs to be improved. Summary of the Invention

[0005] In order to improve the problem that multiple types of aggregates cannot be proportioned simultaneously, resulting in low working efficiency, this application provides a concrete aggregate proportioning device and its use method.

[0006] A concrete aggregate proportioning device provided by this application adopts the following technical solutions: A concrete aggregate proportioning device, comprising a mixing tank and a feeding box. The feeding box is arranged on the top wall of the mixing tank. A feeding port is provided at the bottom of the feeding box, and the feeding port is communicated with the mixing tank. A plurality of baffles are arranged in the feeding box. The baffles are arranged along the width direction of the feeding box, and the baffles can move along the length direction of the feeding box. A fixing component for fixing the baffles on the feeding box is arranged on the feeding box. A feeding component is arranged at the feeding port, and the feeding component is used to control the opening size of the feeding port. A mixing component is arranged in the mixing tank, and a discharge port is provided at the bottom of the mixing tank.

[0007] By adopting the above technical solution, during use, first move a plurality of baffles to divide the feeding box into corresponding number of areas according to the types of aggregates to be mixed. Then pour one type of aggregate into one area, so that multiple types of aggregates are in an independent state in the feeding box and will not be mixed. Then start the feeding component to control the size of the feeding port, so as to control the flow rate of the aggregates flowing out of the feeding port, so as to control the amount of each type of aggregate entering the mixing tank, that is, precise supplement of a small amount of aggregates can be carried out according to the proportion, improving the proportioning accuracy.

[0008] At the same time, when the baffles move, the volume of a single area can be adjusted, so that the area of each area communicated with the feeding port is different, so that the amounts of multiple types of aggregates entering the mixing tank through the feeding port per unit time are not equal, so that multiple types of aggregates always enter the mixing tank in a specified proportion, and the operation is convenient. The setting of the baffles enables the number of areas to be adjusted according to the number of types, that is, the feeding box can load multiple types of aggregates according to the actual situation, so as to realize that multiple types of aggregates can enter the mixing tank simultaneously for proportioning, and the working efficiency is higher.

[0009] Optionally, a guiding block is arranged in the feeding box. The guiding block is arranged along the length direction of the feeding box. A guiding hole is arranged on the baffle, and the guiding block is inserted into the guiding hole and can move relative to each other in the guiding hole.

[0010] By adopting the above technical solution, when moving the baffle, the baffle slides on the guiding block, that is, the guiding block moves relative to each other in the guiding hole. The inner wall of the guiding hole abuts against the side wall of the guiding block, playing a role of limiting and guiding, so that the baffle is not easily tilted and offset, and the stability of the baffle dividing the feeding box is increased.

[0011] Optionally, the fixing component includes a fixing rod and two fixing plates. The fixing rod is arranged along the width direction of the blanking box, and the end of the fixing rod is rotatably connected to the blanking box. Threaded structures with opposite helix directions are provided at both ends of the fixing rod. The two fixing plates are respectively sleeved at both ends of the fixing rod, and the fixing plates are threadedly connected to the fixing rod. The fixing rod rotates to drive the two fixing plates to approach or move away from each other. The baffle is located between the two fixing plates, and the two fixing plates can be simultaneously in contact with the baffle.

[0012] By adopting the above technical solution, the fixing rod is driven to rotate self - sufficiently, so that the two fixing plates move away from each other, thus creating gaps on both sides of the baffle, facilitating the movement of the baffle. When the baffle moves to an appropriate position, the fixing rod is rotated again to make the two fixing plates approach each other until the two fixing plates are simultaneously in contact with the baffle, thereby applying a squeezing force to the baffle to achieve clamping and fixing of the baffle, making the baffle fixed in the blanking box and ensuring that the size of each area is fixed.

[0013] Optionally, the blanking component includes a plurality of rotating rods and a plurality of blanking plates. The ends of the rotating rods are rotatably connected to the blanking box. The plurality of rotating rods are parallel to each other. The plurality of blanking plates correspond to the rotating rods one by one. The blanking plates are fixedly sleeved on the corresponding rotating rods. The plurality of blanking plates are in mutual contact to block the blanking opening. A driving component is provided on the blanking box to drive the plurality of rotating rods to rotate synchronously.

[0014] By adopting the above technical solution, when blanking is required, the driving component is started to drive the plurality of rotating rods to rotate simultaneously, so that the plurality of blanking plates simultaneously rotate in the same direction by the same angle. The part where the blanking box and the blanking opening are connected is the space between adjacent blanking plates. During blanking, the inclined blanking plates can play a guiding role, facilitating the outflow of the aggregate.

[0015] When the flipping angle of the blanking plate is relatively small, the space between adjacent blanking plates is also relatively small, so that the number of aggregates in the blanking box entering the mixing tank per unit time is also less, thereby realizing precise control of the amount of aggregates entering the mixing tank.

[0016] And the blanking plates cover the entire blanking opening, so that each area separated by the blanking box occupies the same amount of space, thereby ensuring that the outflow speed of the aggregates from the blanking opening in each area is equal, making the variable amount of the aggregates entering the mixing tank only the size of the blanking opening corresponding to the area where a single type of aggregate is located, and improving the accuracy of multiple aggregates entering the mixing tank according to the ratio.

[0017] Optionally, the driving assembly includes a rotating rack and a number of rotating gears. The rotating rack is slidably connected to the blanking box. The number of the rotating gears corresponds to the rotating rods one by one. The rotating gear is coaxially fixed to one end of the corresponding rotating rod. The rotating rack meshes with the rotating gear. The movement of the rotating rack is used to drive the synchronous rotation of a number of rotating gears.

[0018] By adopting the above technical solution, the movement of the rotating rack is driven, so that a number of rotating gears rotate simultaneously, thereby realizing that a number of blanking plates rotate in the same direction by the same angle at the same time, so as to ensure that the shielding and restriction of the aggregate in each area are consistent.

[0019] Optionally, the stirring assembly includes a rotating rod and a stirring rod. The rotating rod is vertically inserted into the stirring box. The stirring rod is arranged in the stirring box. The stirring rod is vertically arranged, and the bottom end of the rotating rod is connected to the top end of the stirring rod through a connecting plate. The connecting plate is horizontally arranged. A number of stirring rods are fixed on the stirring rod, and a number of stirring rods are arranged at intervals along the length direction of the stirring rod.

[0020] By adopting the above technical solution, after a variety of aggregates enter the stirring box according to the ratio, the rotation of the rotating rod is driven, so that the stirring rod makes a circular motion with the rotating rod as the axis and the length of the connecting plate as the radius, thereby realizing the stirring and mixing of the aggregates in the stirring box. The stirring rods increase the space occupied by the stirring rod in the stirring box, so that when the stirring rod moves, a number of stirring rods also contact the aggregates, thereby increasing the contact area with the aggregates, being able to drive more aggregates to move, and further improving the uniformity of the aggregate mixing.

[0021] Optionally, a rotating motor is arranged on the connecting plate. The output end of the rotating motor is connected with a cross bar. The cross bar is horizontally arranged. The rotating motor is used to drive the cross bar to rotate on the horizontal plane. Vertical rods are fixed at both ends of the cross bar, and a number of push rods are fixed on the vertical rods. A number of the push rods are arranged at intervals in the vertical direction.

[0022] By adopting the above technical solution, when the rotating rod rotates and drives the connecting plate to drive the stirring rod to move, the mounting motor on the connecting plate moves synchronously, so that the two vertical rods make a circular motion around the rotating rod, that is, the rotating rod and the two vertical rods both move around the rotating rod. The push rods on the vertical rods can increase the amount of the pushed and dispersed aggregates, thereby improving the uniformity of the mixed aggregates.

[0023] At the same time, the rotating motor is started to drive the two vertical rods to make a circular motion with the output shaft of the rotating motor as the axis, so that the two vertical rods move in a large circle with the rotating rod as the axis and move in a small circle around the rotating motor at the same time, further increasing the contact area between the push rods and the aggregates, so that the push rods can fully stir the aggregates and realize more uniform and comprehensive mixing of a variety of aggregates.

[0024] Optionally, a conveyor belt is provided inside the connecting plate. One end of the conveyor belt is coaxially fixed to the output shaft of the chasing motor, and the other end is coaxially fixed to the stirring rod.

[0025] By adopting the above technical solution, when the rotating motor drives the two vertical rods to move in a small circle, the rotating motor also makes the conveyor belt move synchronously, thereby driving the stirring rod to rotate. That is, while the stirring rod revolves around the rotating rod, it also rotates on its own axis, further improving the ability of the stirring rod to disperse the aggregate, making the mixing of various aggregates more sufficient and uniform.

[0026] Optionally, an installation frame is fixed on the mixing box, and rollers are provided at the bottom of the installation frame.

[0027] By adopting the above technical solution, move the installation frame so that the rollers roll and slide on the ground, thereby facilitating the displacement of the mixing box and enabling the mixing box to discharge materials at an appropriate position.

[0028] In a second aspect, a method for using a concrete aggregate proportioning device provided by the present application adopts the following technical solution: S1. First, move the baffle so that the baffle divides the feeding box into multiple areas, and then put various aggregates to be mixed into the corresponding areas. S2. Then, use the feeding assembly to control the size of the feeding port so that the aggregate falls into the mixing box. S3. Start the stirring assembly to fully mix the various aggregates entering the mixing box, and finally the mixed aggregates are discharged from the discharge port of the mixing box.

[0029] In summary, the present application includes at least one of the following beneficial effects: 1. When the baffle moves, it can adjust the volume of a single area, so that the area of each area communicating with the feeding port is different. As a result, the number of various aggregates entering the mixing box through the feeding port per unit time is different, enabling various aggregates to always enter the mixing box in a specified proportion, which is convenient to operate. The setting of the baffle enables the number of areas to be adjusted according to the number of types, that is, the feeding box can load various aggregates according to the actual situation, so that various aggregates can enter the mixing box at the same time for proportioning, and the working efficiency is higher. 2. The two vertical rods move in a large circle with the rotating rod as the axis and at the same time move in a small circle around the rotating motor, increasing the contact area between the push rod and the aggregate, so that the push rod can fully stir the aggregate, realizing more uniform and comprehensive mixing of various aggregates.

Specific embodiments

[0032] The following will further describe the present application in detail with reference to the Figures 1-4 accompanying drawings.

[0033] The embodiment of the present application discloses a concrete aggregate proportioning device and its usage method. Referring to Figure 1 and Figure 2 , the concrete aggregate proportioning device includes a mixing tank 10 and a blanking box 20. A discharge port 11 is opened at the bottom of the mixing tank 10. A mixing assembly 70 is provided in the mixing tank 10. The mixing tank 10 is fixed on a mounting frame 140. The bottom of the mounting frame 140 is rotatably connected with rollers 141. When the aggregates in the mixing tank 10 are mixed, the mounting frame 140 is moved so that the rollers 141 roll and slide on the ground, thereby facilitating the displacement of the mixing tank 10 and enabling the mixing tank 10 to discharge materials at an appropriate position.

[0034] Referring to Figure 2 and Figure 3 , the blanking box 20 is arranged on the top wall of the mixing tank 10. A blanking opening 21 is opened at the bottom of the blanking box 20. The blanking opening 21 is communicated with the mixing tank 10. A plurality of baffles 30 are provided in the blanking box 20. The baffles 30 are arranged along the width direction of the blanking box 20. The baffles 30 can move along the length direction of the blanking box 20. Magnets are embedded in the baffles 30. In the initial state, the plurality of baffles 30 adsorb together and accumulate at one end of the blanking box 20.

[0035] Referring to Figure 2 and Figure 4, wherein a guide block 22 is provided in the blanking box 20. The guide block 22 is arranged along the length direction of the blanking box 20, and the end of the guide block 22 is fixed on the inner wall of the blanking box 20. A guide hole 31 is penetrated through the baffle 30, and the guide block 22 is inserted into the guide hole 31. The guide block 22 is a square block, and the guide hole 31 is a square hole matching the guide block 22. When the baffle 30 moves, the guide block 22 moves relative to the guide hole 31. Due to the corresponding edges and corners, the baffle 30 is not easily deflected and inclined during the movement.

[0036] Refer to Figure 4 , a fixing component 40 for fixing the baffle 30 on the blanking box 20 is provided on the blanking box 20, a blanking component 50 is provided at the blanking port 21, the blanking component 50 is used to control the opening size of the blanking port 21, a stirring component 70 is provided in the stirring box 10, and a discharge port 11 is provided at the bottom of the stirring box 10, achieving the effect of flexibly and accurately controlling the aggregate zoning and mixing.

[0037] Refer to Figure 4 , specifically, the fixing component 40 includes a fixing rod 41 and two fixing plates 42. The fixing rod 41 is arranged along the width direction of the blanking box 20. The fixing rod 41 is embedded in the side wall of the blanking box 20 and can rotate on the blanking box 20. Thread structures with opposite rotation directions are provided at both ends thereof, that is, the fixing rod 41 is a bidirectional lead screw. The fixing plates 42 are arranged along the length direction of the blanking box 20, and the two fixing plates 42 are respectively sleeved at both ends of the fixing rod 41 and are threadedly connected with the fixing rod 41. When the fixing rod 41 rotates, the two fixing plates 42 are driven to approach or separate from each other through screw transmission, so as to clamp or loosen the baffle 30. The end of the fixing rod 41 is connected to the blanking box 20 through a bearing, and the bearing can adopt a deep groove ball bearing or a ball bearing, which has low friction and high load-bearing capacity.

[0038] Refer to Figure 2 and Figure 4 , the blanking component 50 includes a plurality of rotating rods 51 and a plurality of blanking plates 52. The end of the rotating rod 51 is rotatably connected to the blanking box 20. The rotating rod 51 is arranged along the length direction of the blanking box 20. The plurality of blanking plates 52 correspond to the rotating rods 51 one by one. The blanking plates 52 are fixedly sleeved on the corresponding rotating rods 51. The plurality of blanking plates 52 are mutually abutted to block the blanking port 21.

[0039] Refer to Figure 4 , a driving component 60 for driving the plurality of rotating rods 51 to rotate synchronously is provided on the blanking box 20. The driving component 60 includes a rotating rack 61 and a plurality of rotating gears 62. The rotating rack 61 is slidably connected to the blanking box 20. The rotating rack 61 is arranged along the width direction of the blanking box 20. A cylinder is installed on the blanking box 20 through bolts, and the output end of the cylinder is connected to the end of the rotating rack 61 for driving the rotating rack 61 to move horizontally.

[0040] A number of rotating fixed gears correspond one-to-one with the rotating rods 51. The rotating gears 62 are coaxially fixed at one end of the corresponding rotating rods 51. The rotating racks 61 are engaged with the rotating gears 62. The movement of the rotating racks 61 is used to drive the synchronous rotation of the number of rotating gears 62.

[0041] Referring to Figure 2 and Figure 4 , when blanking is required, the cylinder is started, so that the number of rotating gears 62 rotate simultaneously, so as to realize that the number of blanking plates 52 rotate in the same direction by the same angle at the same time. The part where the blanking box 20 and the blanking port 21 communicate is the space between adjacent blanking plates 52. When blanking, the inclined blanking plates 52 can play a guiding role to facilitate the outflow of the aggregate.

[0042] When the flipping angle of the blanking plate 52 is small, the space between adjacent blanking plates 52 is also small, so that the number of aggregates in the blanking box 20 entering the mixing tank 10 through the blanking port 21 per unit time will also be small, thereby realizing precise control of the amount of aggregates entering the mixing tank 10.

[0043] And the blanking plate 52 covers the entire blanking port 21, so that each area separated by the blanking box 20 occupies the same amount of space, thereby ensuring that the outflow speed of the aggregates from the blanking port 21 in each area is equal, so that the variable amount of the aggregates entering the mixing tank 10 is only the size of the blanking port 21 corresponding to the area where a single type of aggregate is located, improving the accuracy of multiple aggregates entering the mixing tank 10 according to the ratio.

[0044] Referring to Figure 1 and Figure 2 , specifically, the mixing assembly 70 includes a rotating rod 71 and a mixing rod 72. The rotating rod 71 is vertically inserted into the mixing tank 10. A rotating motor 12 is installed on the top wall of the mixing tank 10 through bolts. The output end of the rotating motor 12 is coaxially fixed with the rotating rod 71 for driving the rotating rod 71 to rotate self.

[0045] Referring to Figure 1 and Figure 2 , the mixing rod 72 is inserted into the mixing tank 10. The mixing rod 72 is vertically arranged, and the bottom end of the rotating rod 71 is connected to the top end of the mixing rod 72 through a connecting plate 80. The connecting plate 80 is horizontally arranged. A number of stirring rods 721 are fixed on the mixing rod 72. The number of stirring rods 721 are arranged at intervals along the length direction of the mixing rod 72.

[0046] After multiple aggregates enter the mixing tank 10 according to the ratio, the rotating rod 71 is driven to rotate, so that the stirring rod 72 makes a circular motion with the rotating rod 71 as the axis and the length of the connecting plate 80 as the radius, thereby realizing the agitation and mixing of the aggregates in the mixing tank 10. The dial rod 721 increases the space occupied by the stirring rod 72 in the mixing tank 10, so that when the stirring rod 72 moves, several dial rods 721 also contact the aggregates, thereby increasing the contact area with the aggregates, being able to drive more aggregates to move, and further improving the uniformity of the aggregate mixing.

[0047] Refer to Figure 1 and Figure 2 In order to increase the sufficiency of mixing, a rotating motor 90 is installed in the connecting plate 80. The output end of the rotating motor 90 is connected to a cross bar 110. Specifically, the output end of the rotating motor 90 is connected to the center of the cross bar 110. The cross bar 110 is horizontally arranged. The rotating motor 90 is used to drive the cross bar 110 to rotate on the horizontal plane. Vertical rods 120 are fixed at both ends of the cross bar 110, and several push rods 121 are fixed on the vertical rods 120. The several push rods 121 are arranged at intervals in the vertical direction.

[0048] When the rotating rod 71 rotates and drives the connecting plate 80 to drive the stirring rod 72 to move, the mounting motor on the connecting plate 80 moves synchronously, so that the two vertical rods 120 make a circular motion around the rotating rod 71, that is, the rotating rod 71 and the two vertical rods 120 both move around the rotating rod 71. The push rods 121 on the vertical rods 120 can increase the amount of aggregates pushed and dispersed, thereby improving the uniformity of the mixed aggregates.

[0049] At the same time, the rotating motor 90 is started to drive the two vertical rods 120 to make a circular motion with the output shaft of the rotating motor 90 as the axis, so that the two vertical rods 120 move in a large circle with the rotating rod 71 as the axis and at the same time move in a small circle around the rotating motor 90, further increasing the contact area between the push rods 121 and the aggregates, so that the push rods 121 can fully stir the aggregates and realize more uniform and comprehensive mixing of multiple aggregates.

[0050] Refer to Figure 1 and Figure 2 In order to make the stirring rod 72 stir the aggregates more fully, a conveyor belt 130 is provided in the connecting plate 80. One end of the conveyor belt 130 is coaxially fixed with the output shaft of the chasing motor, and the other end is coaxially fixed with the stirring rod 72. When the rotating motor 90 drives the two vertical rods 120 to make a small circle movement, the rotating motor 90 also makes the conveyor belt move synchronously, thereby driving the stirring rod 72 to rotate, that is, making the stirring rod 72 rotate while revolving around the rotating rod 71, further improving the ability of the dial rod 721 to disperse the aggregates and making the mixing of multiple aggregates more fully and evenly.

[0051] The implementation principle of a concrete aggregate proportioning device and its usage method in the embodiments of this application is as follows: By arranging a movable baffle 30 in cooperation with a fixing component 40, the blanking box 20 can be flexibly divided into multiple areas, thereby realizing the zoning control of different aggregates. By arranging a blanking component 50 and a driving component 60, the opening size of the blanking port 21 can be accurately controlled, thereby realizing the accurate control of the aggregate flow rate. By arranging a stirring component 70, various aggregates entering the mixing tank 10 can be fully mixed to ensure the uniformity and consistency of the mixing. The whole device has a compact structure and is easy to operate, which can effectively improve the accuracy of aggregate proportioning and the quality of concrete.

[0052] The embodiments of this application also disclose a practical method for a concrete aggregate proportioning device, including the following steps: S1. First, move the baffle 30 so that the baffle 30 divides the blanking box 20 into multiple areas, and then put various aggregates to be mixed into the corresponding areas. S2. Then, use the blanking component 50 to control the size of the blanking port 21 so that the aggregates fall into the mixing tank 10. S3. Start the stirring component 70 to fully mix various aggregates entering the mixing tank 10, and finally the mixed aggregates are discharged from the discharge port 11 of the mixing tank 10.

[0053] The above are all the preferred embodiments of this application. Without restricting the protection scope of this application accordingly, therefore: All equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
