Description

[0002] Mortar is a bonding material used for bricklaying in construction. It is made of a certain proportion of sand and binder materials (cement, lime paste, clay, etc.) and water. It is also called mortar or mortar. Commonly used mortars include cement mortar, mixed mortar (or cement lime mortar), lime mortar and clay mortar.

However, the mortar raw materials will raise dust when entering the mixer truck. This is mainly because the cement, lime, sand and other materials in the raw materials constantly collide during the feeding and mixing process to produce a large amount of debris and fine particles. These particles float into the air as the machine operates. At present, when the mortar raw materials enter the mixing tank, dust will be raised.

[0016] The present invention has the following beneficial effects: 1. The dust suppression device used in the mortar filling process is connected to the water supply equipment through the dust suppression water supply device to provide a water source for the dust suppression spray device. During the rotation of the mixing tank, the driving ring and the driving protrusion fixedly connected to one end of the mixing tank will continuously resist the top of the piston plate. Due to the cooperation between the driving protrusion and the driving groove on the top of the piston plate, the mixing tank continuously resists the driving groove during the rotation, driving the piston plate to slide downward. At the same time, due to the presence of the piston spring at the bottom of the piston plate, when the driving protrusion does not resist the top of the piston plate, the piston plate will automatically slide upward, and the piston plate will continuously perform piston movement in the piston space, and then the water in the piston space will be discharged outward through the rotary spray device, so as to achieve the adsorption of dust scattered to the entrance of the mixing tank, thereby achieving the dust reduction effect.

When the drive ring rotates with the rotation of the mixing tank, the connecting ring at the bottom of the user drive ring rotates synchronously. Since the side wall of the connecting ring is fixedly connected with a drive tooth block, and the drive tooth block is meshed with the bevel gear, the rotating shaft fixedly connected with the bevel gear rotates synchronously. Since the bottom of the rotating shaft is equipped with a rotating fan blade, the rotating shaft will rotate synchronously with the rotating fan blade during the rotation process. Through the rotation of the rotating fan blade, an airflow can be effectively formed in the installation groove and transported to the rotating output device through the output channel. Through this design, the airflow can be effectively driven to blow toward the water curtain, thereby reducing the possibility of dust falling into the external environment.
[0018] 3. The dust suppression device used in the mortar filling process can further expand the coverage of the airflow sprayed by the pneumatic pressure device through the design of the rotating output device, and further reduce the possibility of dust falling to the outside. While the rotating block rotates, the annular gear ring fixedly connected to the side wall of the rotating block rotates synchronously, and the annular gear ring is meshed with the fixed gear, so the fixed gear will drive the rotating block to rotate synchronously, and the eccentric design of the eccentric channel in the rotating block allows the airflow to be sprayed outward in a fan-shaped state. This design can effectively expand the coverage of the driving device and further reduce the possibility of dust falling to the outside. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0029] Example 1: This example aims to solve the problem that when the mortar raw materials enter the mixing tank for mixing, dust will be raised, which will pollute the environment and seriously affect the health of the surrounding workers. Please refer to Figures 1 to 8 A dust suppression device for use in a mortar filling process comprises a mixing tank 1, a dust suppression water supply device 2 is provided on one side of the mixing tank 1, the dust suppression water supply device 2 comprises a fixed shell 21 provided on one side of the mixing tank 1, a rotating embedded groove 22 is provided in the fixed shell 21, the mixing tank 1 is rotatably connected in the rotating embedded groove 22, a water storage annular groove 23 is provided in the fixed shell 21, and the water storage annular groove 23 supplies water to the dust suppression spray device 3.
[0030] The stirring mixing tank 1 is used to mix and stir the added raw materials (the rotation of the stirring mixing tank 1 is achieved by the cooperation between the motor and the large and small gears. The stirring mixing tank 1 is usually installed on a bracket or a mobile vehicle. In order to ensure the rotation between the stirring mixing tank 1 and the fixed shell 21, the fixed shell 21 is usually fixed on a bracket (unmarked). The above structure and working principle are prior art and are not described in detail in this scheme). During the rotation of the stirring mixing tank 1, the dust reduction spray device 3 is driven to spray. The dust reduction spray device 3 is arranged at the feed inlet of the stirring mixing tank 1. Through this design, the dust raised by the raw materials entering the stirring mixing tank 1 can be effectively reduced.
[0031] The dust suppression spray device 3 includes a piston space 31 opened in the fixed shell 21, the piston space 31 is connected to the water storage ring groove 23 through a one-way water inlet channel 25, and a rotary spray device 4 is arranged at the bottom of the piston space 31. The rotary spray device 4 includes a rotating block 42 arranged in the fixed shell 21, and a spray water outlet channel 46 is opened in the rotating block 42.
[0032] The top of the water storage annular groove 23 is connected to a water supply channel 24 . The water supply channel 24 is opened in the fixed shell 21 . The one-way water inlet channel 25 is opened in the fixed shell 21 .
[0033] The bottom of the piston space 31 is connected to a one-way water outlet groove 32, which is opened in the fixed shell 21. A piston plate 33 is slidably connected in the piston space 31. The bottom of the piston plate 33 is fixedly connected to a piston spring 34, and the other end of the piston spring 34 is fixedly connected in the piston space 31.
[0034] A driving groove 35 is formed on the top of the piston plate 33 . The inner wall of the driving groove 35 abuts against a driving protrusion 37 . The driving protrusion 37 is fixedly connected to the inner wall of a driving ring 36 . The driving ring 36 is fixedly connected to one side of the stirring and mixing tank 1 .
[0035] The dust reduction water supply device 2 is connected to the water supply equipment to provide a water source for the dust reduction spray device 3. During the rotation of the mixing tank 1, the driving ring 36 and the driving protrusion 37 fixedly connected to one end of the mixing tank 1 will continuously resist the top of the piston plate 33. Due to the cooperation between the driving protrusion 37 and the driving groove 35 on the top of the piston plate 33, the mixing tank 1 continuously resists the driving groove 35 during the rotation, driving the piston plate 33 to slide downward. At the same time, due to the presence of the piston spring 34 at the bottom of the piston plate 33, when the driving protrusion 37 does not resist the top of the piston plate 33, the piston plate 33 will automatically slide upward, and the piston plate 33 will continuously perform piston movement in the piston space 31, and then the water in the piston space 31 will be discharged outward through the rotary spray device 4, so as to achieve the adsorption of dust scattered to the entrance of the mixing tank 1, thereby achieving the dust reduction effect.
[0036] Since the piston space 31 is connected with the one-way water inlet channel 25 and the one-way water outlet groove 32, through the one-way design of the two pipes, each time the piston plate 33 in the piston space 31 slides downward, it will squeeze the water in the piston space 31, so that the water is discharged through the rotary spray device 4. When the piston plate 33 slides upward, the piston plate 33 will absorb water from the water storage ring groove 23 through the connection of the one-way water inlet channel 25. Through this one-way connection design, the piston space 31 can be continuously replenished through the water storage ring groove 23. The design of the limit ring 44 and the limit groove 43 effectively ensures the stability of the rotating block 42 during rotation. The one-way water inlet channel 25 is designed to be a semi-ring shape, which will not affect the opening of the installation groove 51, thereby ensuring that the pneumatic pressure device 5 will not affect the normal supply of water during operation.
[0037] The rotary spray device 4 includes a rotating groove 41 opened at the bottom of the fixed shell 21, the rotating groove 41 is connected to the one-way water outlet groove 32, a rotating block 42 is rotatably connected in the rotating groove 41, a side wall of the rotating block 42 is fixedly connected to a limiting ring 44, the limiting ring 44 is rotatably connected in the limiting groove 43, the limiting groove 43 is opened in the fixed shell 21, a water storage groove 45 is opened on the outer wall of the rotating block 42, the water storage groove 45 is connected to the one-way water outlet groove 32, the bottom of the water storage groove 45 is connected to the spray water outlet channel 46, the side wall of the rotating block 42 is fixedly connected to a connecting folding rod 47, and the other end of the connecting folding rod 47 is fixedly connected to the inner wall of the stirring mixing tube 1.
[0038] Since the rotating block 42 is connected to the stirring and mixing tank 1 through the connecting folding rod 47, this connection enables the stirring and mixing tank 1 to rotate while driving the rotating block 42 to rotate synchronously. Through this rotation, the water mist sprayed from the spray outlet channel 46 forms a closed annular water curtain. The formation of this water curtain greatly avoids the dust in the stirring and mixing tank 1 from drifting to the external environment through the water curtain, thereby effectively protecting the environmental quality.
[0039] Example 2: This example is intended to help solve the problem of spraying water mist to absorb dust, but the direction of the water mist falling cannot be guaranteed. This example is an explanation based on Example 1. For details, please refer to Figures 1 to 8 A pneumatic pressure device 5 is arranged in the fixed shell 21. The pneumatic pressure device 5 includes a mounting groove 51 and a rotating groove 52 which are opened in the fixed shell 21. A rotating shaft 53 is rotatably connected in the rotating groove 52. An anti-slip ring 55 is fixedly connected to the side wall of the rotating shaft 53. The anti-slip ring 55 is rotatably connected in the anti-slip groove 54. The anti-slip groove 54 is opened in the fixed shell 21.
[0040] The bottom of the rotating shaft 53 is fixedly connected with a rotating blade 56 . The bottom of the mounting groove 51 is connected with an output channel 57 . The output channel 57 is opened in the fixed housing 21 . The rotating blade 56 is arranged in the mounting groove 51 .
[0041] A driving device 6 is provided at the top of the rotating shaft 53. The driving device 6 includes a bevel gear 63 fixedly connected to the top of the rotating shaft 53. The bevel gear 63 is meshingly connected with a driving gear block 62. The driving gear block 62 is fixedly connected to one side of a connecting ring 61. The connecting ring 61 is fixedly connected to the bottom of the driving ring 36.
[0042] The water ring formed by rotating spray alone may not be able to completely prevent dust from drifting into the external environment. Therefore, the pneumatic pressure device 5 provides airflow from the outside of the water curtain to the inside, so that the dust floating at the entrance is blown inward, which can effectively reduce the possibility of dust falling into the external environment.
[0043] When the driving ring 36 rotates with the rotation of the stirring and mixing tank 1, the connecting ring 61 at the bottom of the driving ring 36 rotates synchronously. Since the side wall of the connecting ring 61 is fixedly connected with the driving tooth block 62, and the driving tooth block 62 is meshed and connected with the bevel gear 63, the rotating shaft 53 fixedly connected with the bevel gear 63 rotates synchronously. Since the bottom of the rotating shaft 53 is installed with a rotating blade 56, the rotating shaft 53 will rotate synchronously with the rotating blade 56 during the rotation process. Through the rotation of the rotating blade 56, an airflow can be effectively formed in the installation groove 51 and transported to the rotating output device 7 through the output channel 57. Through this design, the airflow can be effectively driven to blow toward the water curtain, thereby reducing the possibility of dust falling into the external environment.
[0044] At the same time, the rotating shaft 53 can be set to a hollow design, so that the mounting groove 51 is connected to the rotating embedded groove 22 through the rotating shaft 53. Due to the meshing connection between the driving tooth block 62 and the bevel gear 63 in the rotating embedded groove 22, and the drive between the piston plate 33 and the driving protrusion 37, heat may be generated in the rotating embedded groove 22 due to continuous friction contact. Through the hollow design of the rotating shaft 53 and the rotation of the rotating fan blade 56, the hot air in the rotating embedded groove 22 can be transported to the mounting groove 51. In order to ensure the connection between the water storage ring groove 23 and the piston space 31, the one-way water inlet channel 25 is usually set on the outside of the mounting groove 51. At this time, the heat in the mounting groove 51 can be taken away by the water flowing on the outside. Through this design, the heat generated in the rotating embedded groove 22 can be effectively reduced, thereby ensuring the stability of the operation of the parts in the rotating embedded groove 22.
[0045] Example 3: This example is intended to help solve the problem of low coverage of the directly ejected airflow. This example is an explanation based on Example 2. For details, please refer to Figures 1 to 8 A rotary output device 7 is provided at the other end of the output channel 57. The rotary output device 7 includes a rotary groove 71 opened at the bottom of the fixed shell 21. A rotary block 72 is rotatably connected in the rotary groove 71. A clamping ring 74 is fixedly connected to the side wall of the rotary block 72. The clamping ring 74 is rotatably connected in the clamping groove 73. The clamping groove 73 is opened in the fixed shell 21. An eccentric channel 75 is opened in the rotary block 72.
[0046] A side wall of one end of the rotating block 72 extending out of the fixed housing 21 is fixedly connected to a fixed gear 76 , and the fixed gear 76 is meshedly connected to an annular gear ring 77 , and the annular gear ring 77 is fixedly connected to one side of the rotating block 42 .
[0047] Through the design of the rotating output device 7, the coverage of the airflow ejected by the pneumatic pressure device 5 can be further expanded, and the possibility of dust falling to the outside can be further reduced. When the rotating block 42 rotates, the annular gear ring 77 fixedly connected to the side wall of the rotating block 42 rotates synchronously, and the annular gear ring 77 is meshed with the fixed gear 76, so the fixed gear 76 will drive the rotating block 72 to rotate synchronously, and the eccentric design of the eccentric channel 75 in the rotating block 72 allows the airflow to be sprayed outward in a fan-shaped state. Through this design, the coverage of the driving device 6 can be effectively expanded, and the possibility of dust falling to the outside can be further reduced.
[0048] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
[0049] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
