DETAILED DESCRIPTION
[0026] To make the purpose, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described below in connection with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.
[0027] The embodiments of the present application provide a soil screening device, which can solve the problem of poor screening effect of soil particles in the related art, which are prone to form accumulation on the screen, especially for soil with high humidity or containing a large number of fine particles.
[0028] Please refer to Figures 1-3 A soil screening device includes a support 1 and an elastic support 2 arranged on the support 1, the elastic support 2 is provided with a screening bin 3, the elastic support 2 is used for elastically supporting the screening bin 3, the bottom of the screening bin 3 is provided with a vibrating motor 4, the screening bin 3 has a cavity for soil screening inside, the cavity is provided with a filter screen assembly 5 inside, the filter screen assembly 5 is used for screening soil, the screening bin 3 is provided with a drying mechanism 6, the drying mechanism 6 is used for drying the soil inside the screening bin 3; the drying mechanism 6 includes a shell 61 in communication with the screening bin 3, a plurality of electric heating wires 62 are arranged inside the shell 61, and a fan 63 is arranged at one end of the shell 61.
[0029] On the support 1, the elastic support 2 is arranged for elastically supporting the screening bin 3. The elastic support allows the screening bin 3 to have a certain displacement when subjected to external force, thereby enhancing the screening effect.
[0030] The vibration motor 4 installed at the bottom of the screening bin 3 is the core component of the screening process. When the vibration motor 4 is started, it generates high-frequency vibration, which is transmitted to the soil particles on the filter screen assembly 5 through the screening bin 3. The soil particles collide and jump with each other under the action of vibration, thereby achieving the purpose of screening.
[0031] The filter screen assembly 5 is located in the chamber inside the screening bin 3. Different particle sizes of soil particles are separated on the filter screen assembly 5 under the action of vibration, and the particles meeting the screening requirements pass through the filter screen, while the larger particles are blocked above the filter screen.
[0032] In order to further improve the screening effect, the drying mechanism 6 is arranged on the screening bin 3. The drying mechanism 6 includes a shell 61 communicating with the screening bin 3, and a plurality of electric heating wires 62 are installed inside the shell 61. When the electric heating wires 62 are powered on, they will generate heat to dry the soil inside the screening bin 3. At the same time, the fan 63 arranged at one end of the shell 61 will blow hot air into the screening bin 3 to accelerate the drying process of the soil.
[0033] Through the high-frequency vibration generated by the vibration motor 4, the soil particles are fully mixed and collided in the screening bin 3, accelerating the screening process and improving the screening efficiency. The filter screen assembly 5 effectively separates soil particles of different particle sizes, ensuring the stability of the screening quality. The drying mechanism 6 dries the soil inside the screening bin 3 through the cooperation of the electric heating wires 62 and the fan 63, reduces the adhesion between the soil particles, and is conducive to the screening process. The whole screening device has compact structure and simple operation, reduces the complexity and cost of manual operation.
[0034] In the present embodiment, the screening bin 3 is provided with a discharge hopper 8 at the bottom.
[0035] The discharge hopper 8 is used for the discharge process of the soil after screening, ensuring the continuity and efficiency of the screening process.
[0036] The discharge hopper 8 is usually conical or funnel-shaped, and the bottom opening is small, which helps the soil particles to smoothly slide along the inner wall of the discharge hopper to the lower collecting container or conveying equipment under the action of its own gravity and the vibration of the screening bin.
[0037] In actual operation, the soil is put into the screening bin 3 and screened by the filter screen assembly 5. The vibration motor 4 is started to generate high-frequency vibration, which promotes the mixing, collision and jumping of soil particles in the screening bin to achieve screening. The electric heating wire 62 in the drying mechanism 6 is powered to generate heat, and the fan 63 blows hot air into the screening bin 3 to dry the soil and reduce the adhesion between soil particles. The screened soil particles are separated according to particle size, and the particles meeting the requirements fall through the filter screen assembly 5 into the bottom of the screening bin and slide along the discharge hopper 8 to the lower collecting container or conveying equipment.
[0038] Specifically, as shown in Figure 1 and Figure 5 , the number of the elastic supports 2 in the embodiment is four, and the four elastic supports 2 are distributed in a rectangular shape; the elastic support 2 comprises two oppositely arranged connecting heads 21, a spring 22 is arranged between the two connecting heads 21, and the two connecting heads 21 are respectively connected with the screening bin 3 and the support 1 on the opposite sides.
[0039] The number of the elastic supports 2 is set to four, and the four elastic supports 2 are distributed in a rectangular shape between the support 1 and the screening bin 3, aiming to provide stable and uniform support while allowing the screening bin 3 to vibrate within a certain amplitude under the action of the vibration motor 4.
[0040] Each elastic support 2 is composed of two oppositely arranged connecting heads 21 and a spring 22. The two connecting heads 21 are located at the two ends of the spring 22 and are elastically connected through the spring 22. One connecting head 21 is fixedly connected with the bottom of the screening bin 3, and the other connecting head 21 is fixedly connected with the support 1. When the vibration motor 4 is started, the screening bin 3 will vibrate under the elastic action of the spring 22, thereby realizing the screening of the soil.
[0041] It should be noted that the screening bin 3 in the embodiment is internally hollow, and the upper part is open. A bin cover 7 is arranged on the screening bin 3, the bin cover 7 is provided with a feeding port, and the bin cover 7 is made of transparent material. The bin cover 7 and the screening bin 3 are detachably connected.
[0042] The screening bin 3 is an internally hollow container, and the upper part is open, which is convenient for the input of soil and the discharge of screened soil. The open part of the screening bin 3 is closed by the bin cover 7, and the bin cover 7 is provided with a feeding port for feeding soil into the screening bin.
[0043] The bin cover 7 is made of transparent material, so that the operator can directly observe the screening situation inside the screening bin 3, including the movement state of soil particles, the screening progress, and whether the filter screen assembly 5 needs to be cleaned, etc. The transparent bin cover 7 not only improves the convenience of operation, but also helps to discover and solve possible problems in the screening process in a timely manner.
[0044] In addition, the cover 7 and the screening bin 3 are detachably connected, such as bolt connection, buckle connection, etc. This design makes the cover 7 can be easily opened and closed, and is convenient for cleaning, maintenance and replacement of the filter screen assembly 5 inside the screening bin.
[0045] In one embodiment, as shown in Figure 4 The filter screen assembly 5 includes a work-shaped frame 51 arranged inside the screening bin 3, and a metal filter screen 52 detachably connected to the work-shaped frame 51. A plurality of magnets 53 are embedded above the work-shaped frame 51, and the magnets 53 are tightly attached to the bottom of the metal filter screen 52. The work-shaped frame 51 and the metal filter screen 52 are connected by bolts
[0046] The work-shaped frame 51, as a support structure of the filter screen assembly, is firmly arranged inside the screening bin 3. The design of the work-shaped frame not only provides stable support, but also facilitates the installation and disassembly of the metal filter screen 52.
[0047] Above the work-shaped frame 51, a plurality of magnets 53 are embedded, and the magnets 53 are tightly attached to the bottom of the metal filter screen 52, forming an additional filter layer. The function of the magnets is to adsorb iron impurities in the soil, such as iron filings and small iron blocks, thereby further purifying the screened soil.
[0048] The metal filter screen 52 is detachably connected to the work-shaped frame 51, so that the metal filter screen can be easily replaced when it is worn or clogged, thereby prolonging the service life of the filter screen assembly and maintaining the screening efficiency.
[0049] When the work-shaped frame 51 and the metal filter screen 52 are connected by bolts, this connection method is firm and convenient to disassemble. When it is necessary to replace the metal filter screen 52 or clean the iron impurities adsorbed by the magnets 53, the operator only needs to loosen the bolts to easily complete the related work.
[0050] Further, the housing 61 includes a box body 611 and a pipeline 612 that are in communication with each other, the box body 611 is embedded on one side of the screening bin 3 and in communication with the screening bin 3, the fan 63 is arranged inside the pipeline 612, and the electric heating wire 62 is arranged inside the box body 611; the pipeline 612 is provided with a protective net at the end away from the box body 611. A filter screen is arranged at the communication part between the box body 611 and the screening bin 3.
[0051] The box body 611 is embedded on one side of the screening bin 3 and in communication with the screening bin 3, so that the box body 611 can directly dry the soil in the screening bin 3, improving the drying efficiency. At the same time, a filter screen is arranged at the communication part between the box body 611 and the screening bin 3, which is used to prevent soil particles from entering the inside of the drying mechanism and causing blockage or damage.
[0052] The electric heating wire 62 is arranged inside the box body 611, and generates heat after being electrified to provide a heat source for the drying process. The fan 63 is arranged inside the pipeline 612, and is used to blow hot air into the screening bin 3 to uniformly dry the soil.
[0053] In addition, the pipeline 612 is provided with a protective net at one end away from the box body 611, which is used to prevent external sundries from entering the inside of the drying mechanism, and at the same time, ensure the smooth discharge of hot air. This design not only improves the safety of the drying mechanism, but also ensures its stable operation.
[0054] In one embodiment, the screening bin 3 is further provided with a mounting frame, and the vibration motor 4 is connected to the mounting frame through bolts.
