Description

Technical Field

[0002] Sand mixer is a device that mixes the components of the molding sand evenly and effectively coats the surface of the sand particles with the binder. Sand mixer is the main equipment for casting sand processing and mixing, and is also the key equipment for obtaining qualified molding sand. Sand mixer uses the relative movement of the roller and the plate to crush the material placed between the two by rolling and grinding. Sand mixer mixes the material while crushing it. It is an ideal equipment for producing unburned bricks, lime sand bricks, cement bricks, refractory bricks, crushing and mixing fly ash, boiler slag, tailings and industrial waste slag as raw materials for brick making. Sand mixer, as a key equipment in the casting process, is a key factor in controlling the quality and cost of molding sand.

[0003] In the process of yarn mixing, it is necessary to add raw materials, water and other additives. When the required sand and gravel become viscous due to water and some additives, insufficient mixing will occur during mixing, which may cause agglomeration or adhesion, and further make the sand flow rate unstable and cause inaccurate proportion of mixed sand, thus affecting the quality of the product.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. The present invention provides a stirring unit. When it is necessary to mix relatively viscous sand or gravel with a high water content, before mixing, the adding rod will fall downward and be stuck in the placement groove on the supporting rod one in sequence, so that the adding rod is relatively fixed, thereby increasing the intensity of subsequent stirring and making the mixing more complete.

[0018] 2. The present invention provides a sand shoveling mechanism, and the shovel blade will shovel off the attached gravel. At the same time, the centrifugal force generated by the rotation of the rotating column will move the scratch plate outward, thereby shoveling off the gravel attached to the shovel blade. When the rotating column stops rotating, the tension of the telescopic spring will drive the scratch plate to move in the opposite direction and collide with the impact rod, so that the gravel on the scratch plate will also fall off, thereby achieving self-cleaning.

[0019] 3. The present invention sets an auxiliary mechanism, and the downward movement of the rack will drive the gear to rotate, and then drive the inner column and the magnetic block to rotate, and then the adding rod will also rotate and generate friction with the external sand and gravel, so that the more viscous gravel will not stick to the adding rod.

[0020] 4. The present invention sets a material turning mechanism. The pull rope will pull the sand shoveling plates on both sides to rotate relative to each other, so as to shovel up the sand and gravel raw materials. Then the telescopic rod 2 will drive the fixed plate 2 to move upward. The pulling force of the pull rope will disappear, and the gravity of the weight will drive the sand shoveling plates to separate, so that the shoveled deep sand and gravel will fall to the top layer, avoiding the stratification phenomenon of different sand and gravel raw materials due to different densities when mixed.

[0021] 5. The present invention sets a quantity adjustment mechanism, and the telescopic rod moves downward, so that the baffle plate blocks part of the slot plate, thereby reducing the amount of sand and gravel flowing out. At the same time, the servo motor will also drive the sand and gravel in the sand outlet bin to rotate, so as to prevent the sand and gravel from condensing in the sand outlet bin. When the servo motor is not working, it will also control the direction of the arc plate and the slot plate, thereby controlling the amount of sand and gravel flow. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0038] Example 1, using Figure 1-Figure 14 A sand mixing machine with adjustable sand output flow rate according to one embodiment of the present invention is described as follows.

[0039] like Figure 1-Figure 3As shown, a sand mixing machine with adjustable sand output flow rate of the present invention comprises a bottom plate 1, support legs 2 are evenly arranged on the top of the bottom plate 1, a placing platform 3 is fixedly connected to the top of the support legs 2, a sand mixing bin 4 is fixedly connected to the top of the placing platform 3, a sand grinding mechanism 5 is rotatably connected to the inner wall of the sand mixing bin 4, a lower slide plate 8 is fixedly connected to the top of the sand mixing bin 4, a sand output mechanism 7 is fixedly connected to the bottom of the sand mixing bin 4, an auxiliary mechanism 6 is fixedly connected to the outer surface of the sand mixing bin 4, a sand collecting plate 9 is fixedly connected to one end of the bottom plate 1 close to the sand output mechanism 7, a main motor 10 is fixedly connected to the top of the bottom plate 1, and a speed change device 11 is fixedly connected to the output end of the main motor 10;

[0040] When the present invention is working, after the sand and gravel raw materials are poured into the sand mixing bin 4, the main motor 10 will drive the grinding mechanism 5 to rotate through the speed change device 11, and then mix the raw materials. After mixing for a period of time, the rotation will stop. At this time, the auxiliary mechanism 6 will turn the raw materials over, and finally the raw materials will flow into the sand collecting plate 9 through sand discharge.

[0041] like Figure 4-Figure 5 As shown, the sanding mechanism 5 includes a rotating column 51, a top block 59 is fixedly connected to the top of the rotating column 51, a side plate 52 is fixedly connected to the outer surface of the rotating column 51, and a rolling wheel 53 is rotatably connected to the end of the side plate 52 away from the rotating column 51, a sand shoveling mechanism 54 is fixedly connected to the outer surface of the top block 59, and a stirring unit 55 is fixedly connected to the end of the top block 59 away from the sand shoveling mechanism 54, and an inner column 56 is rotatably connected to the inner wall of the rotating column 51, and a magnetic block 57 is fixedly connected to the side of the inner column 56 close to the stirring unit 55, and a gear 58 is fixedly connected to the end of the inner column 56 away from the magnetic block 57;

[0042] The main motor 10 passes through the speed change device 11 and drives the rotating column 51 to rotate, thereby driving the stirring unit 55 to rotate.

[0043] like Figure 6-Figure 7 As shown, the stirring unit 55 includes a top plate 551, a stirring column 552 is fixedly connected to the bottom of the top plate 551, a support rod 553 is fixedly connected to the outer surface of the stirring column 552, a placement groove 554 is provided on the support rod 553, a telescopic rod 555 is fixedly connected to the inner wall of the top plate 551, one end of the telescopic rod 555 is fixedly connected to a stop block 556, an adding rod 557 is placed on the top of the stop block 556, and a magnetic block 558 is fixedly connected to the end of the adding rod 557 close to the rotating column 51, and the magnetic block 558 and the magnetic block 57 attract each other.

[0044] The stirring column 552 will drive the different sands and additives to be fully mixed. However, when it is necessary to mix more viscous or water-rich sands, before mixing, the telescopic rod 555 will drive the resistance block 556 to move, so that the adding rod 557 falls downward and is stuck in the placement groove 554 on the support rod 553 in turn. The magnetic block 1 57 will attract the magnetic block 2 558, so that the adding rod 557 is relatively fixed, so that the adding rod 557 also plays a certain stirring role, and also increases the area of ​​stirring the sand and gravel raw materials, thereby increasing the intensity of subsequent stirring, making the mixing more complete, and making the viscous sand and gravel raw materials can also be fully mixed.

[0045] The bottom of the rotating column 51 is rotatably connected to the top of the speed change device 11 , and one end of the top plate 551 is fixedly connected to the outer surface of the top block 59 .

[0046] like Figure 8 As shown, the sand shoveling mechanism 54 includes a support plate 541, a shovel blade 543 is fixedly connected to the bottom of the support plate 541, an impact rod is fixedly connected to the end of the support plate 541 close to the top block 59, a support plate 544 is fixedly connected to the outer surface of the support plate 541, a support column 545 is fixedly connected to the end of the support plate 544 away from the top block 59, a scratch plate 547 is slidably connected to the outer surface of the support column 545, a telescopic spring 546 is fixedly connected to the top of the scratch plate 547, and the end of the telescopic spring 546 away from the scratch plate 547 is fixedly connected to the outer surface of the support plate 2 544.

[0047] While the rotating rod is rotating, the crushing wheel 53 on the other side will also crush the sand and gravel raw materials, so that the mixed sand and gravel will not accumulate and form a uniform size. At the same time, when a more viscous or water-rich gravel raw material is needed, the crushing will cause the gravel to adhere to the surface of the crushing wheel 53, thereby affecting the subsequent crushing effect. The scraper 543 will shovel off the attached gravel. At the same time, the centrifugal force generated by the rotation of the rotating column 51 will cause the scratch plate 547 to move outward, thereby shoveling off the gravel attached to the scraper 543. When the rotating column 51 stops rotating, the tension of the telescopic spring 546 will drive the scratch plate 547 to move in the opposite direction and collide with the impact rod 542, so that the gravel on the scratch plate 547 will also fall off, thereby achieving self-cleaning.

[0048] One end of the support plate 541 is fixedly connected to the outer surface of the top block 59 , and the bottom of the scratch plate 547 is in contact with an end of the impact rod 542 away from the top block 59 .

[0049] The specific workflow is as follows:

[0050] During operation, the main motor 10 at the bottom will pass through the speed change device 11 and drive the rotating column 51 to rotate, thereby driving the stirring unit 55 to rotate, and the stirring column 552 will drive the different sands and additives to be fully mixed. Before encountering the viscous raw materials, the telescopic rod 1 555 will drive the blocking block 556 to move, so that the adding rod 557 falls downward and is stuck in the placement groove 554 on the supporting rod 1 553 in turn, and the magnetic block 1 57 will attract the magnetic block 2 558, so that the adding rod 557 is relatively fixed, thereby increasing the intensity of subsequent stirring and making the mixing more complete. When the rotating rod rotates, the crushing wheel 53 on the other side will also crush the sand and gravel raw materials, so that the mixed sand and gravel will not accumulate and form a uniform size. At the same time, the scraper 543 will shovel off the attached gravel. At the same time, the centrifugal force generated by the rotation of the rotating column 51 will cause the scratch plate 547 to move outward, thereby shoveling off the gravel attached to the scraper 543. When the rotating column 51 stops rotating, the tension of the telescopic spring 546 will drive the scratch plate 547 to move in the opposite direction and collide with the impact rod 542, so that the gravel on the scratch plate 547 will also fall off.

[0051] Embodiment 2, use Figure 1-Figure 14 A sand mixing machine with adjustable sand output flow rate according to one embodiment of the present invention is described as follows.

[0052] like Fig. 9 As shown, a sand mixing machine with adjustable sand output flow rate of the present invention is based on the first embodiment, and the auxiliary mechanism 6 includes a fixed plate 1 61, the top of the fixed plate 1 61 is fixedly connected with a telescopic rod 2 62, the top of the telescopic rod 2 62 is fixedly connected with a support plate 3 63, the inner wall of the support plate 3 63 is fixedly connected with a fixing ring 64, the bottom of the support plate 3 63 is fixedly connected with a stabilizing block 65, the bottom of the stabilizing block 65 is fixedly connected with a rack 66, and the outer surface of the support plate 3 63 is fixedly connected with a turning mechanism 67.

[0053] When the sand mixing mechanism stops working and does not hinder the downward movement of the auxiliary mechanism 6, the telescopic rod 2 62 will also drive the support plate 3 63 to move downward, and cause the rack 66 to extend into the rotating column 51. As the rack 66 moves downward, the rack 66 will come into contact with the gear 58, and drive the gear 58 to rotate, thereby driving the inner column 56 and the magnetic block 1 57 to rotate. Since the magnetic block 1 57 and the magnetic block 2 558 fit each other, the adding rod 557 will also rotate and generate friction with the external sand and gravel, so that the more viscous gravel will not stick to the adding rod 557.

[0054] like Figure 10-11As shown, the material turning mechanism 67 includes a second fixed plate 671, a rotating shaft 672 is symmetrically arranged at the bottom of the second fixed plate 671, both ends of the rotating shaft 672 are rotatably connected to the bottom of the second fixed plate 671, a sand scraping plate 673 is fixedly connected to the outer surface of the rotating shaft 672, a striking rod 674 is fixedly connected to the bottom of the second fixed plate 671, a weight block 675 is fixedly connected to the bottom of the sand scraping plate 673, a pull rope 676 is fixedly connected to the top of the sand scraping plate 673, and the end of the pull rope 676 away from the sand scraping plate 673 is fixedly connected to the bottom of the telescopic rod.

[0055] As the support plate three 63 moves downward, the sand shoveling plate 673 will be inserted into the mixed sand and gravel raw materials. Due to the gravity of the weight block 675, the tips of the two sand shoveling plates 673 will face downward. When the support plate three 63 and the fixed plate two 671 move downward for a distance and insert into a deeper layer, the length of the pull rope 676 is fixed, so the sand shoveling plates 673 on both sides will be pulled to rotate relative to each other, thereby shoveling up the sand and gravel raw materials. After that, the telescopic rod two 62 drives the fixed plate two 671 to move upward, the pulling force of the pull rope 676 will disappear, and the gravity of the weight block 675 will drive the sand shoveling plates 673 to separate, so that the shoveled deep sand and gravel fall to the top layer. After that, the sand mixing mechanism will start again and mix, thus avoiding the phenomenon of stratification of different sand and gravel raw materials due to different densities during mixing.

[0056] The outer surface of the fixing plate 1 61 is fixedly connected to the outer surface of the yarn mixing bin, and the top of the fixing plate 2 671 is fixedly connected to the outer surface of the supporting plate 3 63 .

[0057] like Figure 12-13 As shown, the sand discharging mechanism 7 includes a discharging pipe 71, one end of the discharging pipe 71 away from the sand mixing bin 4 is fixedly connected to the sand discharging bin 72, the outer surface of the sand discharging bin 72 is fixedly connected to a support plate 4 73, the end of the support plate 4 73 away from the sand discharging bin 72 is fixedly connected to the outer surface of the placing plate, the inner wall of the sand discharging bin 72 is fixedly connected to a dividing plate 74, the top of the sand discharging bin 72 is fixedly connected to an adjusting mechanism 75, the end of the sand discharging bin 72 away from the discharging pipe 71 is fixedly connected to a support plate 5 76, the outer surface of the support plate 5 76 is rotatably connected to a sealing plate 77, the outer surface of the sealing plate 77 is evenly provided with protruding blocks 78, and the end of the sealing plate 77 away from the support plate 5 76 is fixedly connected to a handle 79.

[0058] The mixed sand and gravel will enter the sand outlet bin 72 through the discharge pipe 71. After the sand and gravel have flowed through the dividing slot plate 74, the sand outlet bin 72 will be sealed by the rotating sealing plate 77. At the same time, the protruding block 78 will pass through the dividing slot plate 74 to prevent the last flowing sand and gravel from adhering to the notch of the dividing slot plate 74 and condensing, thereby causing blockage of the dividing slot plate 74.

[0059] like Fig.14As shown, the adjusting mechanism 75 includes a ring plate 751, the top of the ring plate 751 is fixedly connected to a telescopic rod three 752, the bottom of the telescopic rod three 752 is fixedly connected to a baffle 753, the inner wall of the baffle 753 is fixedly connected to a servo motor 754, the output end of the servo motor 754 is fixedly connected to a rotating shaft two 755, and the bottom of the rotating shaft two 755 is fixedly connected to an arc plate 756.

[0060] When the sand flow rate needs to be adjusted, the telescopic rod will move downward, so that the baffle 753 will resist part of the slot plate 74, thereby reducing the amount of sand and gravel flowing out. At the same time, the servo motor 754 will also drive the sand and gravel in the sand outlet bin 72 to rotate to prevent the sand and gravel from condensing in the sand outlet bin 72. When the servo motor 754 is not working, it will also control the direction of the arc plate 756 and the slot plate 74, thereby controlling the sand and gravel flow rate.

[0061] One end of the discharge pipe 71 is fixedly connected to the bottom of the sand mixing bin 4 , and the bottom of the ring plate 751 is fixedly connected to the outer surface of the sand discharge bin 72 .

[0062] The specific workflow is as follows:

[0063] During operation, the telescopic rod 2 62 will also drive the support plate 3 63 to move downward, and the rack 66 will extend into the rotating column 51. As the rack 66 moves downward, the rack 66 will come into contact with the gear 58, and drive the gear 58 to rotate, thereby driving the inner column 56 and the magnetic block 1 57 to rotate. Since the magnetic block 1 57 and the magnetic block 2 558 fit each other, the adding rod 557 will also rotate and generate friction with the external sand and gravel, so that the more viscous gravel will not stick to the adding rod 557. As the support plate 3 63 moves downward, the sand shoveling plate 673 will be inserted into the mixed sand and gravel raw materials. When the support plate 3 63 and the fixed plate 2 671 move downward for a distance and insert into a deeper layer, the length of the pull rope 676 is fixed, so it will pull the sand shoveling plates 673 on both sides to rotate relative to each other. , thereby shoveling up the sand and gravel raw materials, and then the telescopic rod 2 62 drives the fixed plate 2 671 to move upward, the pulling force of the pull rope 676 will disappear, and the gravity of the weight block 675 will drive the sand shoveling plate 673 to separate, so that the shoveled deep sand and gravel fall to the top layer, and then the sand mixing mechanism will start again and mix, and finally, the mixed sand and gravel will enter the sand outlet bin 72 through the discharge pipe 71. When the sand outlet flow rate needs to be adjusted, the telescopic rod will move downward, so that the baffle 753 will resist part of the slot plate 74, thereby reducing the amount of sand and gravel flowing out. At the same time, the servo motor 754 will also drive the sand and gravel in the sand outlet bin 72 to rotate to prevent the sand and gravel from condensing in the sand outlet bin 72. When the servo motor 754 is not working, it will also control the direction of the arc plate 756 and the slot plate 74, thereby controlling the sand and gravel flow rate.

[0064] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention.
