DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following further describes the utility model in conjunction with the drawings and embodiments.

[0024] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 wherein Figure 1 FIG. 6 is a schematic structural diagram of a preferred embodiment of a screening device provided by the utility model which is convenient for disassembly and installation; Figure 2 is Figure 1 a schematic structural diagram of a partial sectional view of the fixed seat shown in FIG. 7; Figure 3 isFigure 2 Schematic diagram of the structure of area A shown Figure 4 is Figure 1 Schematic diagram of the structure of the partial sectional view of the support plate shown Figure 5 is Figure 4 Schematic diagram of the structure of area B shown, a screening device that is convenient for disassembly and installation, including: a bottom plate 1, a screening component 2 is arranged on the top of the bottom plate 1, and a splitting component 3 is arranged on the top of the screening component 2;

[0025] The screening component 2 includes a fixed seat 21 arranged on the top of the bottom plate 1, two rotating rods 22 are rotatably arranged horizontally before and after inside the fixed seat 21, connecting blocks 23 are arranged in the middle parts of the two rotating rods 22, pulling plates 24 are rotatably arranged inside the two connecting blocks 23, placing blocks 25 are rotatably arranged on the tops of the two pulling plates 24, and a mounting frame 26 is fixedly connected to the tops of the two placing blocks 25;

[0026] Through the rotational cooperation of the rotating rod 22 and the connection relationship between the connecting block 23, the pulling plate 24 and the placing block 25, the mounting frame 26 vibrates up and down to facilitate screening of materials.

[0027] The splitting component 3 includes a mounting block 31 arranged on the top of the mounting frame 26, a support plate 32 is slidably arranged left and right inside the mounting block 31, and a positioning hole 33 is arranged on the top of the mounting frame 26 and on the left side of the mounting block 31.

[0028] By slidably installing the support plate 32 on the outside of the mounting block 31, the installation is completed after the insertion rod 35 enters the positioning hole 33.

[0029] A slot 34 is opened inside the support plate 32, an insertion rod 35 is slidably arranged up and down at the bottom of the support plate 32, and the top end of the insertion rod 35 penetrates through the bottom of the support plate 32 and extends into the inside of the slot 34.

[0030] A baffle 36 is fixedly arranged inside the slot 34 and above the insertion rod 35, a positioning spring 37 is arranged at the bottom of the baffle 36 and at the top end of the insertion rod 35, a cord 38 is fixedly arranged at the top end of the insertion rod 35, and the peripheral side of the cord 38 is slidably connected to the inside of the baffle 36.

[0031] Through the setting of the positioning spring 37, when the support plate 32 slides into the inside of the mounting block 31, the insertion rod 35 will retract, and when the bottom of the insertion rod 35 is located at the top of the positioning hole 33, under the action of the positioning spring 37, the insertion rod 35 will extend and get stuck inside the positioning hole 33, thus completing the installation.

[0032] A rope winding rod 39 is rotatably arranged horizontally on the inner side of the slot 34. The top end of the rope belt 38 is fixed to the circumferential side surface of the rope winding rod 39. The right end of the rope winding rod 39 penetrates through the inner side of the slot 34 and extends to the right side of the support plate 32. A rotating handle 4 is arranged at the right end of the rope winding rod 39. A screening box 5 is arranged on one side of the support plate 32.

[0033] By rotating the rotating handle 4 to drive the rotation of the rope winding rod 39, the rope belt 38 is further pulled short. The shortening of the rope belt 38 will overcome the elastic force of the positioning spring 37, causing the insertion rod 35 to retract. At this time, the support plate 32 can be pulled out from the inside of the mounting block 31. This realizes the function of convenient disassembly.

[0034] A set of connecting rods 27 are arranged at the bottom of the mounting frame 26. The bottom of the connecting rods 27 is slidably connected to the inside of the fixed seat 21. A return spring 28 is arranged at the bottom end of the connecting rods 27 and inside the fixed seat 21.

[0035] After the rotating rod 22 drives the mounting frame 26 to descend, the rotating rod 22 continues to rotate. At this time, the return spring 28 drives the mounting frame 26 to move upward. Thus, repeated vibration is realized.

[0036] The right ends of the two rotating rods 22 both penetrate through the inside of the fixed seat 21 and extend to its right side. A first motor 29 for driving the rotation of the rotating rod 22 is arranged on the right side of the top of the bottom plate 1. The output end on the left side of the first motor 29 is fixedly connected to the right end of the rotating rod 22. The right ends of the two rotating rods 22 are connected by a belt.

[0037] The working principle of a screening device that is convenient for disassembly and installation provided by the present utility model is as follows:

[0038] The first step: During use, by slidably installing the support plate 32 on the outside of the mounting block 31, through the setting of the positioning spring 37, when the support plate 32 slides into the inside of the mounting block 31, the insertion rod 35 will retract. When the bottom of the insertion rod 35 is located at the top of the positioning hole 33, under the action of the positioning spring 37, the insertion rod 35 will extend out and be stuck inside the positioning hole 33, thus completing the installation.

[0039] The second step: Pour the material to be screened into the inside of the screening box 5. By the rotation of the output end of the first motor 29 to drive the rotation of the rotating rod 22, and in cooperation with the connection relationship among the connecting block 23, the pulling plate 24, and the placing block 25, the mounting frame 26 vibrates up and down. After the rotating rod 22 drives the mounting frame 26 to descend, the rotating rod 22 continues to rotate. At this time, the return spring 28 drives the mounting frame 26 to move upward. Thus, repeated vibration is realized to screen the material.

[0040] Step 3: When it is necessary to change the size of the screen mesh, rotate the handle 4 to drive the rotation of the rope winding rod 39, thereby shortening the rope belt 38. The shortening of the rope belt 38 will overcome the elastic force of the positioning spring 37, causing the insertion rod 35 to retract. At this time, the support plate 32 can be pulled out from the inside of the mounting block 31.

[0041] Compared with the related art, a screening device that is easy to disassemble and install provided by the present utility model has the following beneficial effects:

[0042] By sliding the support plate 32 on the outside of the mounting block 31, when the support plate 32 slides into the inside of the mounting block 31, the insertion rod 35 will protrude and be stuck inside the positioning hole 33. Rotating the handle 4 to drive the rotation of the rope winding rod 39, the shortening of the rope belt 38 will overcome the elastic force of the positioning spring 37, causing the insertion rod 35 to retract. At this time, the support plate 32 can be pulled out from the inside of the mounting block 31. The structure is simple and practical, facilitating the quick installation and disassembly of the screening frame 5, and improving the application range and flexibility of the screening device.

[0043] The above are only the embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present utility model.
