Description

Technical Field

[0001] The utility model relates to the technical field of material crushing value determination, in particular to a determination structure for determining the crushing value. Background Art

[0002] The crushing value refers to the performance index of aggregate resistance to crushing. The aggregate crushing value is used to measure the ability of stone to resist crushing under gradually increasing loads. It is an index to measure the mechanical properties of stone. The crushing value is the ratio of the weight of the crushed debris measured by the prescribed test method to the total weight of the sample, expressed as a percentage. It is now convenient and quick to measure the crushing value of coarse aggregate using a crushing value measuring instrument.

[0003] For example, the Chinese patent with authorization announcement number CN211085898U discloses a crushing value measuring instrument for highway engineering measurement, which solves the problem that the existing debris sticks to the pressure column and the measurement results are inaccurate.

At the same time, the instrument manually moves the handle to slide the moving plate, and the moving plate is easily displaced during the vibration of the machine, thereby affecting the crushing work of the pressure column.

DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0027] like Figure 1 As shown, a measuring structure for measuring a crushing value includes a support frame 1, a centralized crushing assembly 2 is installed on the upper left portion of the support frame 1, a discharge assembly 3 is fixedly installed on the right side of the support frame 1, and a collecting and screening assembly 4 is fixedly installed on the lower left portion of the support frame 1.

[0028] The coarse materials put into the centralizing cylinder 21 can be collected by the centralized crushing assembly 2, so that the lower end of the crushing column 24 is always in contact with the coarse materials used, thereby improving the accuracy of the material crushing value. The discharge assembly 3 can move and fix the discharge plate 31 through the cooperation between the threaded rod 32 and the internal threaded sleeve 33, so that the discharge plate 31 can also maintain balance when the instrument vibrates, thereby making the operation of the crushing column 24 more stable. The crushed materials can be uniformly collected by the collection and screening assembly 4, and materials of different sizes can be graded and processed by the filter plate 43 and the receiving box 44, so that materials of different particle sizes can be used in their respective suitable fields, thereby improving the resource utilization rate of the structure.

[0029] like Figure 2 and Figure 3 As shown, the centralized crushing assembly 2 includes a centralized cylinder 21, and three fixing frames arranged in a ring form are fixedly installed on the outer wall of the centralized cylinder 21. The ends of the three fixing frames away from the centralized cylinder 21 are fixedly connected to the upper left part of the support frame 1. The centralized cylinder 21 is a bottomless structure. A mounting frame 22 is fixedly installed on the left rear side of the support frame 1, and a press 23 is fixedly installed on the front lower end of the mounting frame 22. A crushing column 24 is fixedly installed on the output end of the press 23, and the outer wall of the crushing column 24 is movably connected to the inner wall of the centralized cylinder 21.

[0030] Through the press 23, the output end of the press 23 drives the crushing column 24 to move downward, and the crushing column 24 gradually approaches the discharge plate 31, so that the coarse material between the two is squeezed, and the press 23 follows the force and data of the material being gradually crushed for measurement and analysis.

[0031] like Figure 3 and Figure 4 As shown, four installation boxes 25 arranged in a ring form are fixedly installed on the bottom of the outer wall of the concentrating cylinder 21, two sliding rods 26 are fixedly installed on the inner walls of the four installation boxes 25, and slide plates 27 are slidably connected to the outer walls of eight adjacent slide rods 26. Arc-shaped push plates 28 are fixedly installed on one side of the four slide plates 27 close to the axis of the concentrating cylinder 21, and four arc-shaped through grooves 29 arranged in a ring form are opened at the bottom of the outer wall of the concentrating cylinder 21. The upper and lower sides of the four arc-shaped push plates 28 are movably connected to the inner walls of the four arc-shaped through grooves 29.

[0032] The four slide plates 27 are pushed to slide on the corresponding slide bars 26 , and the four slide plates 27 drive the four arc-shaped push plates 28 to enter the concentrating cylinder 21 through the corresponding arc-shaped through grooves 29 , so that the coarse materials put into the concentrating cylinder 21 and scattered on the bottom edge of the inner wall of the concentrating cylinder 21 are pushed to the axial position of the concentrating cylinder 21 , which is convenient for the crushing work of the crushing column 24 .

[0033] like Figure 4 As shown, the outer walls of the eight slide bars 26 are movably sleeved with a reset spring 210 on one side close to the axis of the concentrating tube 21, the ends of the eight adjacent reset springs 210 away from the axis of the concentrating tube 21 are fixedly connected to the sides of the four slide plates 27 close to the axis, and the ends of the eight adjacent reset springs 210 close to the axis of the concentrating tube 21 are fixedly connected to the sides of the inner walls of the four mounting boxes 25 close to each other.

[0034] The elastic restoring force of the eight reset springs 210 can drive the four slides 27 and the four arc-shaped push plates 28 to reset when the force on the corresponding slides 27 is removed, thereby preventing the four arc-shaped push plates 28 from affecting the operation of the crushing column 24 .

[0035] like Figure 5 As shown, the discharge assembly 3 includes a discharge plate 31, the front and rear sides of the discharge plate 31 are slidably connected to the front and rear parts of the inner wall of the support frame 1, the upper end of the discharge plate 31 overlaps the lower end of the concentrating tube 21, and a rotatable internal threaded sleeve 33 is rotatably connected to the middle right side of the support frame 1. The left part of the outer wall of the internal threaded sleeve 33 passes through the right part of the support frame 1, and the inner wall of the internal threaded sleeve 33 is threadedly connected to a threaded rod 32, and the left end of the threaded rod 32 is fixedly installed to the middle right side of the discharge plate 31.

[0036] By rotating the internal threaded sleeve 33, the threaded rod 32 is threadedly connected with the internal threaded sleeve 33 to drive the discharge plate 31 to move. Before the crushing column 24 works, the discharge plate 31 can be moved to the bottom of the concentrating cylinder 21. After the crushing column 24 works, the discharge plate 31 can be removed so that the crushed material automatically falls into the receiving box 41.

[0037] like Figure 5As shown, telescopic rods 34 penetrating the right part of the support frame 1 are fixedly installed on the front and rear parts of the right side of the support frame 1 , and the output ends of the two telescopic rods 34 are fixedly connected to the front and rear parts of the right side of the discharge plate 31 .

[0038] The two telescopic rods 34 limit the movement of the discharge plate 31 .

[0039] like Figure 6 As shown, the collecting and screening assembly 4 includes a material receiving box 41, the upper end of which is fixedly mounted to the left lower end of the support frame 1, the material receiving box 41 is located directly below the discharge plate 31, and slide rails 42 are fixedly mounted on the top positions of the left and right inner walls of the material receiving box 41, filter plates 43 are slidably connected to the opposite sides of the two slide rails 42, and a material receiving box 44 is slidably connected to the bottom of the inner wall of the material receiving box 41.

[0040] Due to the movement of the discharge plate 31 and the scraping of the concentrating cylinder 21, the crushed materials fall into the receiving box 41, and the filter plate 43 separates the materials with lower particle sizes, so that the graded materials can be used in appropriate fields.

[0041] like Figure 7 As shown, sliding sleeves 45 are fixedly installed at the upper and lower positions of the right front part of the material receiving box 41, and the inner walls of the two sliding sleeves 45 are slidably connected with moving rods 46. The right ends of the two moving rods 46 are fixedly installed with connecting plates 47, and the left sides of the two connecting plates 47 are fixedly installed with L-shaped abutment plates 48. The left rear side of the abutment plate 48 abuts against the left front side of the filter plate 43 and the left front side of the material receiving box 44. Springs 49 are fixedly installed at the left ends of the two moving rods 46, and the left ends of the two springs 49 are fixedly connected to the left inner walls of the two sliding sleeves 45.

[0042] The filter plate 43 and the material receiving box 44 can be fixed by the stop plate 48 to prevent the filter plate 43 and the material receiving box 44 from displacement due to structural vibration. The two connecting plates 47 are pulled to move the stop plate 48 away from the filter plate 43 and the material receiving box 44, and at the same time, the two moving rods 46 move and stretch the corresponding springs 49. The elastic restoring force of the springs 49 drives the stop plate 48 to fix the filter plate 43 and the material receiving box 44 again when they are reset.

[0043] The working principle of the utility model is as follows: the staff puts the coarse material to be measured into the concentration cylinder 21. The size of the coarse material is known to be much larger than the size of the four arc-shaped through grooves 29. The staff pushes the four slide plates 27 to slide on the corresponding slide bars 26. The four slide plates 27 drive the four arc-shaped push plates 28 through the corresponding arc-shaped through grooves 29, so that the coarse material in the concentration cylinder 21 is pushed and concentrated. After releasing the four slide plates 27, the elastic restoring force of the corresponding reset springs 210 drives the four arc-shaped push plates 28 to reset. Start the press 23, and the output end of the press 23 drives the crushing column 24 to move downward. The coarse material is actually located at the upper end of the discharge plate 31. Due to the proximity of the crushing column 24, the coarse material is subjected to the extrusion force. The press 23 determines the load and crushing value of the coarse material according to the force analysis of the coarse material being crushed.

[0044] After the determination is completed, the press 23 is started, the crushing column 24 leaves the bottom of the inner cavity of the central tube 21, and pushes the slide plate 27 at the front, so that the corresponding arc-shaped push plate 28 blocks the corresponding arc-shaped through groove 29. Since both ends of the arc-shaped push plates 28 on the left and right are located in the central tube 21, when the discharge plate 31 moves, the two ends can prevent larger crushed materials from passing through the corresponding arc-shaped through groove 29. The internal threaded sleeve 33 is rotated to make the threaded rod 32 drive the discharge plate 31 to move to the right. Due to the scraping action of the central tube 21, the crushed materials fall evenly into the receiving box 41.

[0045] The filter plate 43 collects and classifies the crushed materials, and then pulls the baffle plate 48, which drives the two connecting plates 47 to move, so that the two moving rods 46 slide to the right in the two sliding sleeves 45, so that the two springs 49 are stretched, and the baffle plate 48 releases the limit and fixation of the filter plate 43 and the material receiving box 44, and slides the filter plate 43 and the material receiving box 44 out of the material receiving box 41, and the staff processes the classified coarse materials. Subsequently, the filter plate 43 and the material receiving box 44 are pushed back into the material receiving box 41, and the baffle plate 48 is released. The elastic restoring force of the two springs 49 drives the baffle plate 48 to reset and fix the filter plate 43 and the material receiving box 44 again.

[0046] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
