Description

Technical Field

[0001] The utility model relates to the field of mortar screening and processing, in particular to a mortar mixing screening device. Background Art

[0002] Mortar is the bonding material used for bricklaying in construction. It is made of a certain proportion of sand and cementing materials and water. It is also called mortar or mortar. Common mortars include cement mortar, mixed mortar, lime mortar and clay mortar. Sand is the main material of dry-mixed mortar. The particle size of sand cannot be too different, otherwise the adhesion performance of mortar will be greatly reduced when used. In order to solve this problem, it is necessary to screen the sand before mixing and mixing, and exclude the gravel that does not meet the particle size requirements.

[0003] In a Chinese patent, a dry-mixed mortar sand screening device is disclosed, and its patent number is CN216500696U. In the dry-mixed mortar sand screening device of the patent, the screening machine body, a filter screen A, a motor B, a filter screen B, a gear and a spring A are installed in the screening machine body, and one end of the spring A is connected to the filter screen A, and a tooth plate A is installed on the filter screen A. The screening machine body is installed with a spring B, and the other end of the spring B is connected to the filter screen B, and the filter screen B is installed on the filter screen B. A toothed plate B is installed, a gear is installed at one end of the power shaft of the motor B, the gear is meshed with the toothed plate A, the rack is meshed with the rotating gear, a rotating handle is installed on the rotating gear, a connecting rod is installed on the rack, a moving rod is installed on the connecting rod, a push rod A and a push rod B are installed on the moving rod, and push plates are installed on the push rods A and B. A dry-mixed mortar sand screening equipment is simple to operate, can classify and screen particles of different sizes, and can prevent the filter from being blocked, thereby improving the efficiency of the filtering work.

[0004] The above-mentioned published patents have the following disadvantages:

[0005] (1) In the prior art, since the raw materials of the mortar mixture contain a certain amount of dust, and the raw materials need to be driven to roll inside the equipment, a large amount of dust will float inside the equipment, which will cause a certain amount of dust to adhere to the surface of the components inside the equipment.

[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0028] like Figures 1 to 6 As shown, a mortar mixing screening device includes a shell 1, and the bottom surface of the shell 1 is fixed with supporting legs 2 to support the device. The mortar to be processed will be placed into the inner side of the shell 1 through the feeding port 301 on the surface of the top cover 3 above the shell 1, and a screw 401 is provided at the connecting component 4 at the connection between the shell 1 and the top cover 3 to control the fixed block 1 403 on its surface to cooperate with the fixed block 2 404 on one side to fix the top cover 3 through the clamping block 406. The driving component 5 on the surface of the top cover 3 drives the driving rod 503 to rotate through the driving motor 502, so that the stirring rod 504 on the surface of the driving rod 503 can stir the mortar inside the screen barrel 6. The dust collection components 7 on both sides of the screen barrel 6 are provided with dust collecting ports 701, so that the exhaust fan 702 can collect dust into the inner side of the dust collecting box 703, and the discharge port 8 fixedly connected to the bottom end of the shell 1 controls the outflow of the processed mortar through the valve body 801.

[0029] The moving plate 402 sliding inside the fixing block 1 403 is connected to the screw rod 401 , and a spring 405 is arranged between the fixing block 1 403 and the fixing block 2 404 for buffering, and the clamping block 406 clamped between the fixing block 1 403 and the fixing block 2 404 is connected to the top cover 3 .

[0030] Through the above technical solution, under the action of fixed block 1 403 and fixed block 2 404, the block 406 connected to the top cover 3 can be clamped on the inner side of the two to fix the top cover 3, so that the top cover 3 can be opened and closed at will, ensuring that the sieve barrel 6 inside the shell 1 can be taken out and cleaned at any time.

[0031] The driving assembly 5 is provided with a support frame 501 fixed on the surface of the top cover 3, so that the umbrella gear 1 505 on the surface of the driving rod 503 can rotate inside it, and the umbrella gear 1 505 drives the umbrella gear 3 507 to rotate through the umbrella gear 2 506, so that the connecting ring 508 on the bottom surface of the umbrella gear 3 507 can drive the screen barrel 6 to rotate through the fixing rod 509.

[0032] Through the above technical solution, when the three umbrella-shaped gears are turned downward, the fixing rod 509 can rotate relative to the stirring rod 504, ensuring that it can fully stir the mortar inside the screen barrel 6, and at the same time, it can also screen and filter the mortar through centrifugal force.

[0033] The second bevel gear 506 rotates inside the support frame 501 via a rotating member 561 on one side.

[0034] Through the above technical solution, under the limit of the rotating member 561, the rotation of the second bevel gear 506 can be more stable, thereby ensuring that the fixing rod 509 can rotate relative to the stirring rod 504.

[0035] The connection hole 601 at the upper end of the surface of the screen barrel 6 allows the fixing rod 509 to be inserted into the inner side thereof and fixed by the insertion rod 602 .

[0036] Through the above technical solution, under the action of the insertion rod 602, the fixing rod 509 can be connected to the inner side of the connecting hole 601, so as to facilitate the disassembly and assembly of the sieve barrel 6 and make it easier to clean the large particles inside the sieve barrel 6.

[0037] During use, when the user uses the mortar mixing and screening equipment, the mortar to be processed is placed into the inner side of the shell 1 through the feed port 301, so that the mortar can fall into the inner side of the screen barrel 6. Driven by the drive motor 502, the stirring rod 504 can rotate in different directions from the screen barrel 6 fixed by the insertion rod 602, so that the mortar inside the screen barrel 6 can be mixed and screened by centrifugal force. In this process, the exhaust effect of the exhaust fan 702 allows the floating dust to be collected to the inner side of the dust box 703 through the dust collecting port 701. The processed mortar will be discharged through the discharge port 8 controlled by the valve body 801, and the large particles inside the screen barrel 6 will be removed by the top cover 3 through the connecting component 4, and then the screen barrel 6 will be removed and cleaned by the insertion rod 602.
