Description

Technical Field

[0001] The present application relates to the technical field of sand making machines, and specifically discloses a feeding device for a sand making machine for dry-mixed mortar blanking production. Background Art

[0002] Mortar is the bonding material used for bricklaying in construction. It is made of a certain proportion of sand and binder (cement, lime paste, clay, etc.) plus water. The binder includes cement, lime paste, clay, etc.

[0003] According to the application form, mortar can be divided into two categories: premixed mortar (commercial mortar) and on-site mixed mortar; the cementitious materials used can be divided into cement, gypsum, lime, water glass and phosphate.

[0004] Among them, dry-mixed mortar refers to a special improved dry-mixed mortar designed and produced using high-quality polymers. It is an improved cement-based dry powder material made of a reasonable proportion of high-quality Shijing cement, selected fine aggregate and polymer additives. It only needs to be added with water at the construction site and stirred mechanically as required before use.

[0005] The preparation of dry-mix mortar involves adding various ingredients and mixing them in a sand making machine to produce the desired dry-mix mortar. In the prior art, vertical sand making machines typically have two hoppers installed on top of the machine. After pre-loading the hoppers with a nominal amount of ingredients, the hoppers are opened during the sand making process to allow the ingredients to be discharged into the machine, where they are then uniformly mixed. However, the uniform addition of large quantities of ingredients during the initial stages of dry-mix mortar preparation can increase the accumulation of ingredients within the machine, correspondingly increasing the difficulty of mixing in the initial stages.

[0006] Therefore, in view of this, the inventor provides a sand making machine feeding device for dry mixed mortar feeding production to solve the above problems. Utility Model Content

[0007] The purpose of the utility model is to solve the problem that the feeding device of the traditional sand making machine directly feeds the stored ingredients into the sand making machine before sand mixing, increases the degree of ingredient accumulation inside the sand making machine, and increases the mixing difficulty in the initial stage of dry mixed mortar preparation.

[0008] In order to achieve the above-mentioned purpose, the basic scheme of the present invention provides a feeding device for a sand making machine for dry-mixed mortar feeding production, including a dividing assembly connected to the sand making machine and a hopper connected to the dividing assembly and used for feeding ingredients. The dividing assembly includes a dividing platform with an annular chamber inside, a dividing plate coaxially rotating in the annular chamber, a partition detachably connected to the annular chamber and a driving structure provided on the dividing platform and used to drive the dividing plate to rotate. A feeding port for connecting the annular chamber and the hopper is provided on one side of the top of the dividing platform, and a discharge port for connecting the annular chamber and the inner cavity of the sand making machine is provided on the other side of the bottom of the dividing platform. A plurality of accommodating chambers are circumferentially opened between the two end surfaces of the dividing plate, and a plurality of dividing sleeves that respectively wrap the accommodating chambers are vertically slidably connected to the bottom end of the dividing plate. The bottom ends of the dividing sleeves are all against the top end surface of the partition, and the partition is provided with a dividing outlet connected to the discharge port.

[0009] Furthermore, connecting rods are fixed between the inner walls of the distribution plates on both sides of the accommodating chamber, and elastic parts are fixed on the connecting rods. The inner walls of the distribution platform on both sides of the feed port are provided with several active shifting blocks for shifting the connecting rods to shake.

[0010] Furthermore, each of the connecting rods is provided with a driven shift block that can engage with the active shift block.

[0011] Furthermore, the elastic member includes a first elastic vertical rod which is fixed to the connecting rod and can pass through the annular chamber and extend into the feed port.

[0012] Furthermore, a second elastic vertical rod is fixedly connected to the inner side of each driven shift block.

[0013] Furthermore, a plurality of guide chutes for accommodating the distribution sleeves respectively are opened upward at the bottom end of the distribution plate, and a spring is provided between the top surface of the guide chute and the top end of the distribution sleeve.

[0014] Furthermore, guide plates are provided on the partitions on both sides of the material distribution outlet, respectively extending into the material outlet on the same side.

[0015] Furthermore, the driving structure includes a rotating shaft rotatably connected to the material distribution table and driving the material distribution plate to rotate, a driving motor arranged on the material distribution table, and an intermittent transmission mechanism arranged between the output shaft of the driving motor and the rotating shaft.

[0016] The principle and effect of this solution are:

[0017] Compared with the prior art, the present invention installs a dividing assembly between the sand making machine and the hopper, and provides an annular chamber through the dividing platform in the dividing assembly. Ingredients are fed into the annular chamber from the feed port and discharged through the discharge port. The ingredients entering the annular chamber are stored in several accommodating chambers separated by the rotating dividing disk, and the height of the dividing sleeve can be controlled by adjusting the height of the partition, thereby controlling the volume of the accommodating chamber and controlling the amount of ingredients discharged from the discharge port each time, so as to reasonably distribute the amount of ingredients fed into the sand making machine each time, solving the problem that the feeding device of the traditional sand making machine directly feeds the stored ingredients into the sand making machine before sand mixing, thereby increasing the degree of ingredient accumulation inside the sand making machine and increasing the difficulty of mixing in the initial stage of dry mixed mortar preparation.

[0022] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0024] A feeding device for a sand making machine for dry-mix mortar blanking production, for example Figure 1 、 Figure 2 and Figure 3As shown:

[0025] It includes a material distribution assembly installed on the top of the sand making machine 1 and a hopper 3 installed on the material distribution assembly. In this embodiment, the sand making machine 1 used is a vertical sand making machine 1. There are two inlets on the top of the sand making machine 1. Each hopper 3 stores a rated amount of independent types of ingredients.

[0026] The material distribution assembly includes a material distribution platform 2 fixedly mounted on the top of the sand making machine 1 and having an annular chamber inside, a material distribution plate 9 installed in the annular chamber and rotatable, a partition 14 installed in the annular chamber, and a driving structure 4 installed on the material distribution platform 2 for rotating the material distribution plate 9.

[0027] Among them, the material distribution platform 2 is cylindrical as a whole, and the annular chamber is arranged coaxially with the material distribution platform 2. The top end surface of the material distribution plate 9 is in contact with the inner top surface of the material distribution platform 2. An axial hole is opened at the axis center of the material distribution platform 2. The driving structure 4 includes a rotating shaft 6 installed in the axial hole and rotatable, a bracket fixedly installed on the top of the material distribution platform 2, a driving motor 7 fixedly installed on the bracket, and an intermittent transmission mechanism connected between a section of the rotating shaft 6 extending out of the axial hole and the output shaft of the driving motor 7. The intermittent transmission mechanism includes a rotating arm 8 coaxially fixedly installed on the output shaft of the driving motor 7 and a groove wheel coaxially fixedly installed on the rotating shaft 6. A number of cylindrical pins are fixedly installed below the rotating arm 8, which can be placed in the radial groove of the groove wheel and drive the groove wheel to rotate.

[0028] In this embodiment, a feed port for connecting the annular chamber with the bottom end of the hopper 3 is opened on one side of the top end of the distribution platform 2, and a discharge port for connecting the annular chamber with the inner cavity of the sand making machine 1 is opened on the other side of the bottom end of the distribution platform 2.

[0029] There are also several accommodating chambers 19 circumferentially opened between the two end surfaces of the distribution plate 9. The accommodating chambers 19 are connected to the annular chamber, and when the accommodating chambers 19 are turned to below the feed port, the materials discharged from the bottom end of the hopper 3 will pass through the feed port and fall into the accommodating chambers 19 below; when the accommodating chambers 19 are turned to above the feed and discharge ports, the materials stored in the accommodating chambers 19 will fall from the discharge port into the inner cavity of the sand making machine 1 below.

[0030] Among them, the bottom end of the distribution plate 9 is also equipped with several distribution sleeves that respectively wrap the accommodating chamber 19, and the bottom ends of the distribution sleeves are all against the top end face of the partition 14, and the partition 14 is located at the same position of the discharge port and has a distribution outlet connected to the discharge port.

[0031] Specifically, the bottom of the distribution tray 9 is formed with several guide slots 10 extending upward, each encompassing a receiving chamber 19. The top end of the distribution sleeve fits within these slots, and the entire sleeve slides vertically along these slots. Springs are installed between the top surface of the guide slots 10 and the top end of the distribution sleeve, pressing the sleeve downward so that its bottom end always abuts against the top end surface of the partition 14. In this embodiment, the distribution sleeve consists of two radial sleeves 11 and two transverse sleeves 18 mounted between the ends of the radial sleeves 11.

[0032] The distribution tray 9 also has a vertical limit chute. The partition 14 is circular in shape, with its outer wall fitting closely to the inner wall of the distribution tray 9. A support plate is welded to one side of the partition 14, with a stud welded to the support plate. The stud extends through the limit chute and is tightened with a nut 5, securing the partition 14 in place. The height of the partition 14 can be adjusted by turning the nut 5. Rubber pads 12 are fixedly mounted on the inner walls of both sides of the limit chute. The inner end faces of the rubber pads 12 fit together to seal the limit chute, and the stud can separate the rubber pads 12 at the corresponding height. Furthermore, adjusting the height of the partition 14 can adjust the volume of each accommodating chamber 19 accordingly.

[0033] Furthermore, a guide plate 13 extending below the discharge port on the same side is welded to the partitions 14 on both sides of the material distribution outlet, so that the guide plates 13 on both sides and the inner wall of the material distribution platform 2 form a material drop channel to prevent the falling ingredients from falling into the remaining annular chamber below the partition 14.

[0034] Furthermore, on the material distribution plate 9, a connecting rod 16 is installed between the inner walls on both sides of each accommodating chamber 19, and an elastic member is connected to the middle of the connecting rod 16. Specifically, the elastic member is a first elastic vertical rod 15. The top of the first elastic vertical rod 15 is against the top surface of the material distribution platform 2, and the bottom is higher than the bottom height of the material distribution plate 9. When the first elastic vertical rod 15 is input into the feed port, the top of the first elastic vertical rod 15 will extend into the feed port. In this embodiment, a driven shift block 17 is also integrally formed on the connecting rod 16, and a continuous active shift block is formed at equal distances on the inner walls of the material distribution platform 2 on both sides of the feed port. When the connecting rod 16 enters the two sides of the feed port, the active shift block engages with the driven shift block 17, which will drive the connecting rod 16 to vibrate, and then drive the first elastic vertical rod 15 to vibrate, thereby playing a role in vibration and anti-blocking when the ingredients fall from the hopper 3 into the accommodating chamber 19. In this embodiment, a second elastic vertical rod with a bottom height higher than the bottom height of the distribution tray 9 is also connected to the lower inner side of the driven shift block 17 .

[0035] When the utility model is used, the partition 14 is first adjusted and fixed to a predetermined height so that the volume of each accommodating chamber 19 reaches a predetermined ingredient ratio, thereby performing reasonable ingredient distribution during the continuous mixing process of the dry-mixed mortar and improving the mixing efficiency;

[0036] Then the drive motor 7 is started, and the drive motor 7 drives the rotating shaft 6 to rotate intermittently through the intermittent transmission mechanism, driving the material distribution plate 9 to rotate intermittently, and then the accommodating chambers 19 are placed under the feed port and fed respectively. The ingredients are stored in the accommodating chambers 19, and in the subsequent rotation process, the ingredients are discharged through the accommodating chambers 19 entering the discharge port, realizing the feeding of the sand making machine 1, thereby completing the mixing of the dry mixed mortar.

[0037] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
