Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a sand screening device for building civil engineering construction. Background Art

[0002] The sand screening device for civil engineering construction, also known as a sand screening machine, is a device specially used for screening sand. Its main function is to screen the sand according to construction requirements, remove stones, impurities, etc., so as to obtain sand materials that meet the construction requirements. The working principle of the sand screening machine mainly relies on the different apertures of the screen to separate sand materials of different particle sizes to achieve the purpose of removing impurities. When the equipment is started, the motor drives the screen to rotate at high speed, and the sand material is thrown above the screen. As the screen rotates, the sand falls through the screen holes, while larger particles such as stones and impurities are blocked above the screen and finally discharged through the outlet.

[0003] The invention relates to a sand screening device for use in construction and civil engineering projects, and the invention relates to a sand screening device for use in construction and civil engineering projects, comprising a support frame, a support leg fixedly mounted on the bottom of the support frame, a discharge port being provided in the middle of the bottom of the support frame, the discharge port being connected to a collecting box, the top of the collecting box being connected to the bottom of a baffle hopper, the screening mechanism comprising a dispersion mechanism arranged above the baffle hopper, a vibrating mechanism being arranged below the dispersion mechanism, the vibrating mechanism being mounted on the outer surface of the support frame, the dispersion mechanism can knock and disperse the sand blocks that have clumped together, thereby making the filtering and screening process more sufficient, improving the efficiency and quality of the screening device, and driving the screen to perform a reciprocating motion left and right through the action of the vibration mechanism push plate, so that the sand can be automatically screened, thereby solving the problem of traditional manual screening.

[0004] The above patent can solve the problem that large sand clumps can be beaten and dispersed, so that the sand can be filtered more fully during the screening process, thereby improving the efficiency and quality of the screening device. The vibrating mechanism pushes the screen to move back and forth, so that the sand can be automatically screened, thereby solving the problem of traditional manual screening. However, if the traditional sand screening device for construction and civil engineering is not equipped with an anti-blocking mechanism, the following problem will occur: the screen, the main working component of the sand screening machine, is prone to blockage when the sand contains a large amount of impurities or the humidity is high. This blockage will seriously affect the screening efficiency of the sand screening machine and even cause the equipment to fail to work properly. Utility Model Content

Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0030] The present invention will be further described below with reference to the embodiments.

[0031] Example

[0032] See also Figure 1-Figure 4 , the utility model provides the following technical solutions:

[0033] A sand screening device for construction and civil engineering, comprising:

[0034] Two devices support the stand 1;

[0035] The driving mechanism is provided on one side of the device support stand 1. The driving mechanism includes a first rotating shaft 2, a first cooperating rotator 3, a first fixer 4 and a first motor 5. There are two first rotating shafts 2 and two first cooperating rotators 3. The two first rotating shafts 2 are respectively rotatably connected to the two device support stands 1. The two first cooperating rotators 3 are respectively fixedly connected to the circumferential surfaces of the two first rotating shafts 2. The first fixer 4 is fixedly connected to the outer surface of the device support stand 1. The first motor 5 is fixedly connected to the upper end of the first fixer 4;

[0036] The cleaning mechanism is respectively arranged on the circumferential surface of the cleaning driving rod 501.

[0037] In a specific embodiment of the present invention, two devices support the stand 1 as the basic frame, supporting the entire equipment. The core components of the driving mechanism include a first rotating shaft 2, a first cooperating rotator 3, a first fixer 4 and a first motor 5. Among them, the two first rotating shafts 2 are connected through the first cooperating rotator 3 to form a linkage mechanism. When the first motor 5 is started, its power is transmitted to the first rotating shaft 2 through the first fixer 4, so that the two first rotating shafts 2 rotate synchronously, thereby driving the screening mechanism connected thereto to operate. The cleaning mechanism is installed on the cleaning drive rod 501. The design of the cleaning drive rod 501 ensures that while screening sand, it can effectively remove impurities accumulated on the screen to prevent blockage and ensure screening efficiency.

[0038] For details, please refer to Figure 1-Figure 4 The cleaning mechanism includes a cleaning drive rod 501, a second cooperating rotator 6 and an anti-clogging sweeper 7. There are two second cooperating rotators 6 and anti-clogging sweepers 7. The cleaning drive rod 501 is rotatably connected to the first motor 5. The cleaning drive rods 501 are rotatably connected to the two first rotating shafts 2. The two second cooperating rotators 6 are fixedly connected to the circumferential surface of the cleaning drive rod 501. The two anti-clogging sweepers 7 are rotatably connected to the two second cooperating rotators 6 respectively.

[0039] In this embodiment: the operating principle of the cleaning mechanism is based on the linkage mechanism of the cleaning drive rod 501, the second cooperating rotator 6 and the anti-clogging sweeper 7. The cleaning drive rod 501 is directly connected to the first motor 5 to accept its power input. At the same time, it is connected to the two first rotating shafts 2 through rotation, ensuring the stable rotation of the cleaning drive rod 501. The second cooperating rotator 6 is fixed to the circumferential surface of the cleaning drive rod 501. When the cleaning drive rod 501 rotates, the second cooperating rotator 6 rotates accordingly, driving the two anti-clogging sweepers 7 to move synchronously. The anti-clogging sweeper 7 is connected to the second cooperating rotator 6 through rotation. As the cleaning drive rod 501 rotates, the anti-clogging sweeper 7 can effectively remove impurities attached to the screen, prevent the screen holes from being blocked, and maintain screening efficiency.

[0040] For details, please refer to Figure 1-Figure 4 The outer surfaces of the two first matching rotators 3 are fixedly connected with a screening drum 8, and the outer surface of the device supporting stand 1 is fixedly connected with a second fixture 9.

[0041] In this embodiment: the outer surfaces of the two first cooperating rotators 3 are fixedly connected to the screening drum 8, which means that when the first cooperating rotator 3 is driven to rotate by the power source, it directly drives the screening drum 8 fixedly connected thereto to rotate synchronously. This design ensures the continuous operation of the screening drum 8 and provides a power basis for sand screening. At the same time, the outer surface of the device support frame 1 is fixedly connected to the second fixture 9. This fixture not only provides additional structural stability for the entire device, but may also be used to fix other auxiliary components, such as motor brackets, control panels, etc., to ensure the stability of the entire screening device during operation. Through the linkage between the screening drum 8 and the first cooperating rotator 3, and the structural support provided by the second fixture 9, this design realizes an efficient and stable screening process, improves screening efficiency and screening accuracy, and is suitable for sand screening operations in large-scale construction and civil engineering.

[0042] For details, please refer to Figure 1-Figure 4 One side end of the second fixer 9 is fixedly connected to the second motor 10, and the second rotating shaft 11 is rotatably connected inside the second motor 10.

[0043] In this embodiment: one side end of the second fixer 9 is fixedly connected to the second motor 10. This design ensures the stable installation of the motor and provides a stable foundation for subsequent power transmission. The second rotating shaft 11 rotatably connected inside the second motor 10 directly receives the power generated by the motor. As the motor starts, the second rotating shaft 11 begins to rotate. This linkage mechanism directly converts the rotational kinetic energy of the motor into mechanical motion.

[0044] For details, please refer to Figure 1-Figure 4 The circumferential surface of the second rotating shaft 11 is fixedly connected with a gear 12, and the circumferential surface of the screening drum 8 is fixedly connected with a gear ring 13, and the gear 12 and the gear ring 13 are meshed.

[0045] In this embodiment: a gear 12 is fixedly connected to the circumferential surface of the second rotating shaft 11. At the same time, a gear ring 13 is fixedly connected to the circumferential surface of the screening drum 8. The two are designed to be in a meshing state, which means that when the second motor 10 drives the second rotating shaft 11 to rotate, the gear 12 fixed on the rotating shaft rotates accordingly. Due to the meshing relationship between the gear 12 and the gear ring 13, the rotation of the gear 12 directly drives the gear ring 13, and then the screening drum 8 starts to rotate. This method of transmitting power through the meshing of the gear 12 and the gear ring 13 ensures the high efficiency and accuracy of power transmission, so that the rotation speed and direction of the screening drum 8 can be precisely controlled.

[0046] For details, please refer to Figure 1-Figure 4 The lower ends of the two device support frames 1 are fixedly connected to a base 14, and the upper ends of the base 14 are fixedly connected to two sand baffles 15.

[0047] In this embodiment: the lower ends of the two device support frames 1 are fixedly connected to the base 14. This design is intended to provide a stable support foundation for the entire screening device to ensure the stability of the equipment during the screening operation. The upper end of the base 14 is further fixedly connected to two sand retaining plates 15. The function of these sand retaining plates 15 is to prevent sand from splashing out under the action of centrifugal force when the screening drum 8 rotates to screen sand, causing material loss and pollution of the working environment. The setting of the sand retaining plates 15 not only helps to keep the screening area clean and reduce cleaning work, but also improves screening efficiency because the sand is effectively confined within the screening area, avoiding the need for repeated screening.

[0048] For details, please refer to Figure 1-Figure 4 The lower end of the base 14 is fixedly connected to a plurality of stands 16 , and the lower end of the base 14 is fixedly connected to a sand outlet 17 .

[0049] In this embodiment: the lower end of the base 14 is fixedly connected to a plurality of uprights 16. This design enhances the structural stability and supporting strength of the entire screening device, ensuring that during the screening process, even when facing a large load of sand, the equipment can remain stable, reduce vibration, and extend its service life. At the same time, the presence of the uprights 16 also increases the distance between the bottom of the equipment and the ground, facilitating the movement and maintenance of the equipment. The lower end of the base 14 is also fixedly connected to a sand outlet 17, which serves as an outlet for qualified sand after screening. Its position and design ensure that the screened sand can be discharged smoothly and quickly, avoiding the backlog of materials inside the equipment and improving the screening efficiency.

[0050] The working principle and use process of the utility model are as follows: First, the second motor 10 drives the second rotating shaft 11 to rotate, and the gear 12 on the second rotating shaft 11 engages with the gear ring 13 on the screening drum 8, so that the screening drum 8 starts to rotate, providing power for the screening process. At the same time, the first motor 5 is started to drive the cleaning drive rod 501 to rotate, and the second matching rotator 6 on the cleaning drive rod 501 drives the anti-blocking sweeper 7 to operate, effectively clearing the blockage on the surface of the screening drum 8 to ensure screening efficiency. The material is added from the top of the device and enters the rotating screening drum 8. The large particles of material are intercepted, and the small particles of sand that meet the requirements pass through the screen and fall into the base 14 area. The sand retaining plate 15 above the base 14 prevents sand from splashing during the screening process, keeping the working environment clean. After the screening is completed, the qualified sand is discharged from the sand outlet 17 at the lower end of the base 14 and falls into the collection container. The multiple stands 16 at the lower end of the base 14 ensure that the equipment is stable as a whole and is easy to move between different construction sites. By using this device, the following problems will arise if the traditional sand screening device for civil engineering construction does not have an anti-blocking mechanism: the screen, the main working component of the sand screening machine, is prone to blockage when the sand contains a large amount of impurities or the humidity is high. This blockage will seriously affect the screening efficiency of the sand screening machine and may even cause the equipment to fail to work properly.

[0051] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
