Technical Field

[0001] The utility model relates to the technical field of aggregate screening, in particular to an aggregate screening device for prefabricating concrete tower barrels. Background Technique

[0002] Aggregates, as key components in concrete and mortar, play the roles of skeleton and filling in the mixture, and have a direct impact on the mechanical properties and durability of concrete. According to different particle sizes, aggregates can be divided into coarse aggregates and fine aggregates, and each fineness of aggregate has its specific uses. Coarse aggregates can enhance the compressive strength of concrete, while fine aggregates help improve the density and impermeability of concrete.

[0003] Aggregate screening is a physical process of using screening equipment to divide aggregates into different particle size levels to meet the quality requirements of specific engineering materials. However, in the actual concrete production process, traditional screening equipment often can only screen aggregates of a single particle size and usually cannot screen out aggregates of multiple particle sizes simultaneously.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] The present utility model provides an aggregate screening device for prefabricating concrete tower barrels, as Figure 1 and Figure 2 shown. The screening device includes a bottom plate 1, a column 6 fixedly installed on the top of the bottom plate 1, a moving plate 2 movably installed on the top of the column 6, a side plate 3 fixedly installed on the moving plate 2, a sieve plate 8 fixedly installed on the side plate 3 for aggregate screening, a baffle 9 fixedly installed on the sieve plate 8, a guide plate 7 fixedly installed on the moving plate 2, an installation table 11 fixedly installed on the bottom plate 1, and a driving component fixedly installed on the installation table 11 for driving the moving plate 2 to move.

[0021] A retaining plate 10 is fixedly connected to the sieve plate 8, a number of sieve holes are provided on the sieve plate 8, and a discharge port is provided on the side plate 3.

[0022] The sieve plate 8 of this screening device is used to screen aggregates. The sieve holes on the sieve plate 8 are divided into two groups. The aperture of the sieve holes in the first group is smaller than that in the second group. This setting is to screen out three different sizes of aggregates. When the moving plate 2 is driven by the driving component, it can drive the sieve plate 8 to produce a vibrating effect to screen the aggregates. The baffle 9 is used to slow down the sliding speed of the aggregates on the sieve plate 8 and improve the screening efficiency. The aggregates screened from the sieve plate 8 will fall onto the moving plate 2 at the bottom. A guide plate 7 is fixedly installed on the moving plate 2 corresponding to the end position of each group of sieve holes. A discharge port is provided on the side plate 3, and the discharge port corresponds to the guide plate 7 to guide the aggregates to separate from the device at a specific position. The aggregates still on the sieve plate 8 after two screenings will finally separate from the device at the rear end of the sieve plate 8.

[0023] Furthermore, in order to enable the moving plate 2 to achieve a vibrating effect, as Figure 1 , Figure 2 and Figure 3 shown, the driving component includes a fixed block 12 fixedly installed on the installation table 11, an eccentric shaft 16 rotatably installed inside the fixed block 12, a first transmission wheel 14 fixedly installed at one end of the eccentric shaft 16, a transmission rod 17 movably connected to the eccentric shaft 16, a first motor 13 fixedly installed on the installation table 11, and a second transmission wheel 24 fixedly installed on the output end of the first motor 13.

[0024] The bottom of the moving plate 2 is fixedly connected with a pulley 4, the pulley 4 is slidably connected inside the slide rail 5, the bottom of the moving plate 2 is fixedly connected with a connecting block 18, and one end of the transmission rod 17 away from the eccentric shaft 16 is movably connected to the inside of the connecting block 18 through a plugging rod. A belt 15 is sleeved on the first transmission wheel 14 and the second transmission wheel 24 together.

[0025] Since the first transmission wheel 14 and the second transmission wheel 24 are connected by a belt 15, when the first motor 13 is started, the first transmission wheel 14 can be indirectly rotated. The first transmission wheel 14 is connected to the eccentric shaft 16, and the transmission rod 17 is connected to the bottom of the moving plate 2. When the eccentric shaft 16 rotates, the moving plate 2 can be driven through the transmission rod 17, so that the moving plate 2 can reciprocate inside the slide rail 5 through the pulley 4 at the bottom, thereby achieving the vibration effect.

[0026] Furthermore, in order to facilitate the feeding of the staff, as Figure 1 and Figure 4 shown, a vertical plate 23 is fixedly connected to the top of the bottom plate 1, a feeding cylinder 21 is fixedly connected to the vertical plate 23, a feeding shaft 22 is rotatably connected inside the feeding cylinder 21, and the feeding shaft 22 penetrates through the feeding cylinder 21.

[0027] Since the feeding position of this screening device is relatively high and it is inconvenient to perform the feeding operation, the feeding cylinder 21 and the feeding shaft 22 are provided. The feeding cylinder 21 is placed obliquely, and the higher end is located at the top of the sieve plate 8 and is provided with a discharge port. The staff can feed from the lower end of the feeding cylinder 21. After the aggregate comes into the inside of the feeding cylinder 21, the rotating feeding shaft 22 can convey it to the higher end of the feeding cylinder 21, and then it falls onto the sieve plate 8 through the discharge port.

[0028] Still further, in order to enable the feeding shaft 22 to rotate, as Figure 1 and Figure 4 shown, one end of the feeding cylinder 21 is fixedly connected with a sleeve 19, the bottom of the sleeve 19 is fixedly connected to the top of the bottom plate 1, and a second motor 20 is fixedly connected inside the sleeve 19. The output end of the second motor 20 is fixedly connected with one end of the feeding shaft 22.

[0029] The sleeve 19 is fixedly connected with the bottom plate 1, which further improves the stability of the feeding cylinder 21 during operation. A second motor 20 is installed inside the sleeve 19. By connecting the output end of the second motor 20 to the feeding shaft 22, the feeding shaft 22 can be directly driven to rotate.

[0030] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
