Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1-5A small geotechnical screening device for geotechnical engineering includes a laboratory small geotechnical vibrating screen body 1. A reinforcement mechanism 2 is provided on the outside of the laboratory small geotechnical vibrating screen body 1. The reinforcement mechanism 2 includes a contact component 201 and an adjustment component 202. The contact component 201 is provided on the outside of the laboratory small geotechnical vibrating screen body 1, and the adjustment component 202 is provided on the outside of the contact component 201.
[0026] The contact assembly 201 includes a support ring 201a, a receiving channel 201b, a sliding rod 201c, a spring 201d, and a wrapping plate 201e. The support ring 201a is disposed on the outside of the laboratory small rock and soil vibrating screen body 1. The receiving channel 201b is movably connected to the inside of the support ring 201a. The sliding rod 201c is slidably connected to the inside of the receiving channel 201b. The spring 201d is fixedly connected to the surface of the receiving channel 201b. The wrapping plate 201e is fixedly connected to the surface of the sliding rod 201c near the side of the laboratory small rock and soil vibrating screen body 1.
[0027] In this embodiment: by setting up a bearing ring 201a, a receiving channel 201b, a sliding rod 201c, a spring 201d, and a wrapping plate 201e, when using this small geotechnical engineering geoscopy device, the user can attach the bearing ring 201a to the outside of the laboratory small geotechnical vibrating screen body 1, so that the receiving channel 201b, sliding rod 201c, spring 201d, and wrapping plate 201e housed inside can be close to the screen equipment. At this time, the wrapping plate 201e should be in contact with the surface of the screen equipment. When the screen equipment shakes and vibrates, it will drive the wrapping plate 201e to move towards the receiving channel 201b, thereby driving the sliding rod 201c to move inside the receiving channel 201b, while squeezing the spring 201d, so that the spring 201d deforms inside the wrapping plate 201e and the receiving channel 201b, in order to avoid the wrapping plate 201e directly colliding rigidly with the screen equipment.
[0028] Specifically, such as Figure 2 , Figure 4 As shown, the adjustment component 202 includes a bottom support plate 202a disposed at the bottom of the laboratory small rock and soil vibrating screen body 1. Fixing holes are provided around the top of the bottom support plate 202a. An adjustment support rod 202b is bolted to the top of the bottom support plate 202a. The top of the adjustment support rod 202b is bolted to the bottom of the bearing ring 201a.
[0029] Specifically, such as Figure 2 , Figure 4 As shown, a threaded adjusting rod 202c is provided at the top of the adjusting support rod 202b, and a rotating handle is fixedly connected to the side of the threaded adjusting rod 202c away from the laboratory small rock and soil vibrating screen body 1.
[0030] Specifically, such as Figure 2 , Figure 4 As shown, the threaded adjusting rod 202c is rotatably connected to the bearing plate 202d on the side near the main body 1 of the laboratory small rock and soil vibrating screen, and the surface of the threaded adjusting rod 202c away from the adjusting support rod 202b is smooth.
[0031] In this embodiment: by setting a bottom support plate 202a, an adjusting support rod 202b, a threaded adjusting rod 202c, and a bearing plate 202d, when adjusting the contact component 201, the user can combine the bottom support plate 202a with the bottom vibration device set inside the laboratory small soil and rock vibrating screen body 1, so that it can be placed on top of the vibration device. At the same time, the adjusting support rod 202b fixed on its top can support and fix the bearing ring 201a. When the user uses different screen devices, the position of the adjusting support rod 202b on the bottom support plate 202a can be changed according to the volume of the screen device, thereby adjusting the bearing ring 201a and other structures. Moreover, the surface of the receiving channel 201b is provided with the bearing plate 202d and the threaded adjusting rod 202c. By rotating the threaded adjusting rod 202c, it can drive the bearing plate 202d, the receiving channel 201b, the sliding rod 201c and other structures closer to or away from the screen device, thereby completing the adjustment of the contact component 201 to assist the user in completing the small soil and rock screening work.
[0032] Specifically, such as Figure 1 , Figure 5 As shown, an auxiliary component 3 is provided on the outer side of the laboratory small rock and soil vibrating screen body 1. The auxiliary component 3 includes a storage ring 301 rotatably connected to the surface of the threaded adjusting rod 202c, and a measuring plate 302 is slidably connected to the bottom of the inner side of the storage ring 301.
[0033] Specifically, such as Figure 1 , Figure 5 As shown, an anti-detachment block 303 is fixedly connected to the surface of the measuring plate 302 away from the laboratory small rock and soil vibrating screen body 1, and a measuring scale is opened on the surface of the measuring plate 302.
[0034] In this embodiment: by setting up a storage ring 301, a measuring plate 302, and an anti-detachment block 303, the storage ring 301, the measuring plate 302, and the anti-detachment block 303 cooperate with each other, so that they can be used as a reference structure. When the user rotates the threaded adjustment rod 202c, the thread will drive the receiving channel 201b and other structures to move. At this time, the storage ring 301, which is located on its smooth surface, moves, so that the user can observe the scale on the surface of the measuring plate 302, which can help the user adjust the three contact components 201 to a relatively consistent position. The anti-detachment block 303 can prevent the measuring plate 302 from falling.
[0035] Specifically, such as Figure 3 As shown, a threaded hole is provided on the inner side of the bearing ring 201a away from the wrapping plate 201e, and a groove is provided on the inner side of the receiving channel 201b.
[0036] Specifically, such as Figure 3 As shown, the surface of the receiving channel 201b near the main body 1 of the laboratory small rock and soil vibrating screen is fixedly connected to the surface of the spring 201d, the surface of the wrapping plate 201e is arc-shaped, and a protective pad is adhered to the surface of the wrapping plate 201e.
[0037] In this embodiment: by setting up a bearing ring 201a, a receiving channel 201b, a spring 201d, and a wrapping plate 201e, the bearing ring 201a, the receiving channel 201b, the spring 201d, and the wrapping plate 201e cooperate with each other to serve as a reinforcing structure for the screen equipment, thereby preventing the screen equipment from falling off during vibration.
[0038] Working Principle: Firstly, this device is used for screening small-scale soil and rock samples. When using this small-scale soil and rock screening device for geotechnical engineering, the user can attach the bearing ring 201a to the outside of the laboratory small-scale vibrating screen body 1, allowing the internal receiving channel 201b, sliding rod 201c, spring 201d, and wrapping plate 201e to approach the screen equipment. At this time, the wrapping plate 201e should be in contact with the surface of the screen equipment. When the screen equipment shakes and vibrates, it will drive the wrapping plate 201e to move towards the receiving channel 201b, thereby driving the sliding rod 201c to move inside the receiving channel 201b, simultaneously compressing the spring 201d. This causes the spring 201d to deform inside the wrapping plate 201e and the receiving channel 201b, preventing the wrapping plate 201e from directly colliding rigidly with the screen equipment. When adjusting the contact component 201, the user can... The user can combine the bottom support plate 202a with the bottom vibration device inside the laboratory small soil and rock vibrating screen body 1, so that it can be placed on top of the vibration device. At the same time, the adjustable support rod 202b fixed on the top can support and fix the bearing ring 201a. When the user uses different screen devices, the position of the adjustable support rod 202b on the bottom support plate 202a can be changed according to the volume of the screen device, thereby adjusting the bearing ring 201a and other structures. Moreover, the surface of the receiving channel 201b is provided with a bearing plate 202d and a threaded adjusting rod 202c. By rotating the threaded adjusting rod 202c, it can move the bearing plate 202d, receiving channel 201b, sliding rod 201c and other structures closer to or away from the screen device, thereby adjusting the contact component 201 to assist the user in completing small soil and rock screening work.
[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the scope of the present utility model should be included within the protection scope of the present utility model.
