Detailed Implementation

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] like Figures 1-7 As shown, an automatic vibrating screen device for geotechnical sieving test includes a box body 1, a feed hopper 11 connected to the middle of the upper end of the box body 1, a door 12 hinged to the front side of the box body 1, a grading vibrating screen assembly 2 movably connected to the inner wall of the box body 1, and a filter plate disassembly assembly 3 fixedly installed on the right side of the grading vibrating screen assembly 2.

[0030] The grading vibrating screen assembly 2 includes two rotating shafts 21. The front and rear ends of the two rotating shafts 21 are fixedly installed at the upper and lower positions of the left side of the inner wall of the box 1. The middle of the outer wall of each of the two rotating shafts 21 is rotatably connected to an inclined guide plate 22. The front left side of each of the two guide plates 22 is provided with an installation groove 23. The inner wall of each of the two installation grooves 23 is movably connected to a filter plate 24. The screen holes of the two filter plates 24 decrease in size from top to bottom. The upper and lower right sides of the box 1 are provided with discharge troughs. The right side of each of the two guide plates 22 extends out of the two discharge troughs and is movably sleeved with the inner wall of the two. The upper and lower right sides of the box 1 are fixedly installed with a fixing plate 25. The two fixing plates 25 are flush with the bottom of the two discharge troughs. The upper end of each of the two fixing plates 25 is fixedly installed with a number of linearly arranged buffer springs 26. The upper end of the number of buffer springs 26 is fixedly connected to the edge of the lower right side of the two guide plates 22. The lower right side of the two guide plates 22 is movably connected to a drive mechanism.

[0031] The filter plate disassembly assembly 3 includes two rectangular sleeves 31. The front right side of each of the two guide plates 22 is provided with a fixing groove. The outer sides of the two rectangular sleeves 31 are fixedly installed with the inner walls of the two fixing grooves. The inner walls of the two rectangular sleeves 31 are slidably connected with sliding plates 32. The front middle of each of the two sliding plates 32 is fixedly installed with a connecting rod 33. The front ends of each of the two connecting rods 33 are rotatably connected with a pull plate 34. The rear left side of each of the two pull plates 34 is fixedly installed with a locking block 35. The front right side of each of the two filter plates 24 is provided with a slot 36 for matching two locking blocks 35.

[0032] The material injected into the inside of the box 1 from the feeding hopper 11 can be classified and screened by the hierarchical vibrating screen assembly 2, so that the material can be effectively packed in the collecting box 217 and the two packing boxes 216 according to the particle size, and multiple screening of the material can be achieved, and the screening effect is good. The two filter plates 24 can be quickly separated from the two guide plates 22 through the filter plate dismounting assembly 3. When the filter plate 24 is worn or blocked due to long-term use, workers can easily take it out of the mounting groove 23, which is convenient for cleaning and replacement, and reduces the maintenance cost.

[0033] As shown in Figure 6 The left and right sides of the two filter plates 24 are slidably connected with the inner walls of the two sliding grooves 27.

[0034] The sliding grooves 27 have a guiding effect on the installation / dismounting of the filter plates 24.

[0035] As shown in Figure 5 The driving mechanism includes a worm 28, the upper and lower ends of the worm 28 are rotatably connected with the right rear side of the box 1, a motor 29 is fixedly installed on the top of the rear side of the box 1, the output end of the motor 29 is fixedly connected with the upper end of the worm 28, drive shafts 210 are rotatably connected with the right positions of the upper and lower parts of the rear side of the box 1, worm gears 211 are fixedly sleeved with the rear parts of the outer walls of the two drive shafts 210, and the outer surfaces of the two worm gears 211 are engaged with the outer wall of the worm 28.

[0036] The output end of the motor 29 can drive the worm 28 to rotate, the two worm gears 211 are driven to synchronously rotate by engaging with the worm 28, so that the two cams 212 continuously press the two guide plates 22. Thus, the two guide plates 22 rotate around the corresponding rotating shafts 21, and continuously stretch and compress the buffer springs 26, so as to realize the vibrating screening of the material when the material passes through the filter plates 24.

[0037] As shown in Figure 5 The outer walls of the two drive shafts 210 are fixedly sleeved with cams 212, and the outer surfaces of the two cams 212 are abutted with the right parts of the lower ends of the two guide plates 22.

[0038] As shown in Figure 6 The upper front and rear parts of the two filter plates 24 are fixedly installed with baffle plates one 213, and the right positions of the upper front and rear parts of the two guide plates 22 are fixedly installed with baffle plates two 214.

[0039] The baffle plates one 213 and the baffle plates two 214 can prevent the material from splashing when falling.

[0040] As shown in Figure 4 and Figure 5As shown, support frames 215 are fixedly installed on the upper and lower parts of the right side of the box 1. The two support frames 215 are located below the corresponding guide plates 22. Dispensing boxes 216 are slidably connected to the bottom of the inner wall of the two support frames 215. A collection box 217 is movably connected to the bottom of the inner wall of the box 1.

[0041] The particles screened out on the two filter plates 24 will drip into the dispensing box 216 due to the tilt of the two guide plates 22, while the smallest particles will fall into the collection box 217.

[0042] like Figure 7 As shown, a return spring 37 is fixedly installed on the rear side of each of the two slide plates 32, and the rear ends of the two return springs 37 are fixedly connected to the rear inner wall of the two rectangular sleeves 31.

[0043] The return spring 37 has a resetting function for the slide plate 32. When installing the filter plate 24, the elastic force of the return spring 37 can assist the slide plate 32 and the locking block 35 to move to the correct position so that the locking block 35 can be smoothly inserted into the slot 36 of the filter plate 24.

[0044] The working principle of this utility model is as follows: During use, material is injected into the housing 1 from the feed hopper 11. Due to gravity, the material moves from top to bottom and is separated by the two filter plates 24. Simultaneously, the motor 29 starts, and its output drives the worm gear 28 to rotate. The two worm wheels 211 mesh with the worm gear 28, driving the two drive shafts 210 to rotate synchronously, causing the two cams 212 to continuously press against the two guide plates 22. This causes the two guide plates 22 to rotate around their respective shafts 21, continuously stretching and compressing several buffer springs 26, thus achieving vibration screening when the material passes through the filter plates 24. Particles screened out on the two filter plates 24 drip into the dispensing box 216 due to the tilt of the two guide plates 22, while the smallest particles fall into the collection box 217. For unified cleaning, the two dispensing boxes 216 can be slid out to the right from their corresponding support frames 215. Cleaning the collection box 217 simply requires opening the door 12 and removing it.

[0045] When filter plates 24 become worn or clogged due to prolonged use, the worker opens the door 12 and moves the two pull plates 34 forward. The pull plates 34 move the corresponding connecting rods 33 and slide plates 32 forward, causing the two return springs 37 to stretch under tension. The pull plates 34 then move the locking blocks 35 away from the slots 36 on the filter plates 24. The two pull plates 34 are then rotated so that they rotate upwards around the two connecting rods 33, preventing interference with the filter plates 24. At this point, the worker can slide the two filter plates 24 forward from the two mounting slots 23. The installation steps for the filter plates 24 are the same as above and will not be elaborated further.

[0046] The basic principle and main features of the present application and the advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
