Description

[0001] The invention relates to the technical field of sand detection, in particular to a machine-made sand measuring device. Background Art

[0002] Artificial sand refers to sand processed by sand making machines and other auxiliary equipment. The finished product is more regular and can be processed into sand of different rules and sizes according to different process requirements, which can better meet daily needs. Artificial sand requires professional equipment to produce qualified and applicable sand and gravel. The quality of the manufactured sand needs to be monitored during the production process of artificial sand, such as the water content, particle size, mud powder content and other parameters of the artificial sand.

[0003] Regarding the above-mentioned related technologies, it is believed that: when measuring the particle distribution of machine-made sand, the machine-made sand is generally screened in sequence, and then the machine-made sand particles of different particle sizes after screening are weighed to obtain the weight distribution of sand particles of different particle sizes in a certain weight of machine-made sand.

[0016] The present invention has the following beneficial effects:

[0017] (1) In the machine-made sand measuring device, the support table drives the support seat, the rotating shaft and the containing frame to move. The sample sand is subjected to vibration and shaking in the containing frame. When the particle size of the sample sand is smaller than the screening hole of the screening plate, the small-size sample sand continues to move downward and is finally screened by several layers of screening plates and remains on the receiving plate. The weighing device is started, and the handle drives the corresponding containing frame and the connecting seat to rotate 90 degrees on the outer wall of the rotating shaft, driving the first magnet to separate from the adsorption of the second magnet and separate from the inner wall of the limit frame. After the containing frame rotates 90 degrees, the position of the screening plate matches the receiving hopper. The right side of the rotating screening plate drives the connecting seat to rotate 90 degrees. The shaft rotates in the inner wall of the containing frame, the sealing ring breaks away from the contact with the limit ring, the screening plate flips over and the sample sand pours down onto the weighing equipment in the receiving hopper and the receiving frame, and the sample sand of the particle size is weighed by the weighing equipment, and the data is fed back to the external controller. The sample machine-made sand can be screened first, and the particles of different particle sizes can be placed in layers to avoid mutual interference. The layered sample machine-made sand is weighed and the data is recorded in turn, so the content of sand particles of different particle sizes in the sample sand can be determined. Therefore, the overall process is simple and the data is more accurate when in use, and it is not cumbersome for the staff to operate.

[0018] (2) The machine-made sand measuring device puts the sample sand into the uppermost containing frame, and the vibration device drives the vibration table, the contact table and the top plate to vibrate. The top plate drives the sliding seat to slide up and down slightly on the outer wall of the positioning rod. The sliding seat compresses the movable spring, and the sliding seat is pushed to slide up and down continuously on the outer wall of the positioning rod under the elastic action of the movable spring. The top plate vibrates and moves up and down, and at the same time, it drives the support table to move synchronously. When screening the machine-made sand, the screening efficiency of the sand particles can be improved by the vibration and up and down movement, which can shorten the screening time and facilitate the subsequent weighing and measurement of the machine-made sand after screening.

[0019] (3) In the machine-made sand measuring device, the controller controls the electric push rod to push the push plate out of contact with the receiving groove and slide in the inner wall of the receiving frame. The push plate pushes the weighed sample sand on the top wall of the weighing device to the left, driving the sealing seat to start flipping and break away from the contact with the side wall of the receiving frame and leak out of the sand outlet, so that the sample sand can be smoothly discharged from the sand outlet into the receiving frame and collected together. By repeating the above operation, sample sands of different particle sizes can be weighed, and the machine-made sand after screening can be weighed in turn. Before the next weighing, the machine-made sand on the weighing device can be pushed away and collected together, and a space can be reserved for the next weighing, which can improve the overall work energy efficiency.

[0020] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

During the screening process, magnet 1 47 and magnet 2 49 are in an adsorption state, which can prevent the containing frame 45 from rotating. When weighing is required after the screening is completed, the screening plate 410 can be pressed downward to drive the connecting shaft 414 to rotate in the inner wall of the containing frame 45, thereby driving the sealing ring 413 out of contact with the inner wall of the containing frame 45, so that the retained artificial sand on the screening plate 410 is poured downward to perform load-bearing work, thereby determining the content of sand particles of different particle sizes in the sample sand.

[0036] Specifically, the support platform 41 is square, a limit seat is fixedly installed on the top of the rotating shaft 43, a number of connecting seats 44 are linearly arranged up and down, a number of containing frames 45 are circular, the outer walls of the several containing frames 45 are in contact with each other, the screening holes of the several screening plates 410 become smaller from top to bottom, the outer walls of the several sealing rings 413 are in contact with the corresponding inner walls of the containing frames 45, and the inner walls of the several sealing rings 413 are hollow.

[0037] In this embodiment, the outer walls of several containing frames 45 are in contact with each other to prevent the machine-made sand from leaking out from the gaps during screening. The inner wall of the sealing ring 413 is hollow. When the sealing ring 413 is squeezed, it will be slightly deformed, which facilitates the rotation of the screening plate 410.

[0038] Specifically, the bottom walls of several limit rings 412 are fitted with the corresponding top walls of the sealing rings 413, the outer walls of several containing frames 45 are fixedly installed with handles 46, the front walls of the limit frames 48 are fitted with the rear parts of the corresponding outer walls of the containing frames 45, and several magnets 1 47 are adsorbed and fixed to magnet 2 49.

[0039] In this embodiment, when the accommodating frame 45 needs to be rotated, the accommodating frame 45 needs to be driven to rotate by the handle 46 .

[0040] Specifically, the vibration assembly 3 includes a top plate 38, the top plate 38 is located at the bottom of the support platform 41, the top wall of the top plate 38 is fixedly connected to the bottom wall of the support platform 41, the bottom wall of the top plate 38 is fixedly installed with a contact platform 39, a mounting groove 31 is opened in the middle of the top wall of the workbench 1, a vibration device 32 is installed on the inner wall of the mounting groove 31, a vibration platform 310 is fixedly installed on the top wall of the vibration device 32, and the top wall of the vibration platform 310 is in contact with the bottom wall of the contact platform 39.

[0041] In this embodiment, when the vibration device 32 is in operation, it will drive the vibration table 310 and the contact table 39 to vibrate, thereby driving the top plate 38 to vibrate.

[0042] Specifically, positioning seats 33 are fixedly installed on the top wall of the workbench 1 and at the four corners of the outer edge of the mounting groove 31, and limiting blocks 35 are fixedly installed on the top walls of several positioning seats 33. Positioning rods 34 are fixedly installed on one side adjacent to several positioning seats 33 and corresponding limiting blocks 35, and sliding seats 37 are slidably installed on the outer walls of several positioning rods 34. The outer walls of several sliding seats 37 are fixedly connected to the outer wall of the top plate 38.

[0043] In this embodiment, the sliding seat 37 and the positioning rod 34 cooperate with each other to limit and fix the top plate 38, thereby preventing the top plate 38 from shifting in position when vibrating.

[0044] Specifically, the top and bottom walls of the sliding seats 37 are fixedly mounted with movable springs 36 , the ends of the movable springs 36 that are away from each other are fixedly connected to the corresponding limit blocks 35 and the positioning seats 33 , and the movable springs 36 are sleeved on the outer wall of the positioning rod 34 .

[0045] In this embodiment, when the top plate 38 vibrates, it drives the sliding seat 37 to slide on the outer wall of the positioning rod 34, thereby compressing the movable spring 36, and pushing the sliding seat 37 and the top plate 38 to move up and down under the elastic action of the movable spring 36.

[0046] Specifically, the weighing assembly 2 includes a receiving frame 25 , the bottom wall of the receiving frame 25 is fixedly connected to the front of the top wall of the workbench 1 , a receiving hopper 26 is fixedly mounted on the top wall of the receiving frame 25 , and a weighing device 27 is fixedly mounted on the inner bottom wall of the receiving frame 25 .

[0047] In this embodiment, the weighing device 27 is mainly used to weigh the manufactured sand, and the hopper 26 can receive the dumped manufactured sand.

[0048] Specifically, a sand outlet 24 is opened on the left side wall of the receiving frame 25 , and a sealing seat 22 is rotatably mounted on the left side wall of the receiving frame 25 and located at the top of the sand outlet 24 through a hinge seat 23 , and the sealing seat 22 fits against the inner wall of the sand outlet 24 .

[0049] In this embodiment, the sand outlet 24 is mainly used to discharge the machine-made sand after weighing is completed. When the pushing plate 210 does not push the material, the sealing seat 22 seals the sand outlet 24 .

[0050] Specifically, a receiving groove 28 is opened on the right side wall of the receiving frame 25, a U-shaped frame 29 is fixedly installed on the right side wall of the receiving frame 25, an electric push rod 211 is fixedly installed on the right side wall of the U-shaped frame 29, and the movable ends of the electric push rod 211 slide through the U-shaped frame 29 and the receiving frame 25 in sequence. The outer wall of the push plate 210 is slidably connected to the inner wall of the receiving frame 25, and the push plate 210 is located in the inner wall of the receiving groove 28.

[0051] In this embodiment, with the cooperation between the electric push rod 211 and the push plate 210, the push plate 210 can push out the machine-made sand on the weighing device 27 during the time gap of rotating the containing frame 45, thereby reserving space for the next weighing.

[0052] Specifically, a material receiving frame 21 is fixedly installed on the top wall of the workbench 1 and located on the left side of the sand outlet 24 .

[0053] In this embodiment, the main function of the material receiving frame 21 is to collect the machine-made sand that has been weighed.

[0054] When working, firstly, the weighing device 27, the electric push rod 211, and the vibration device 32 are connected through the external power supply and the controller. The initial state of the whole device is Figure 1In the state shown, when it is necessary to measure the content of sand particles of different particle sizes inside the machine-made sand, the sample sand is put into the uppermost containing frame 45, and then the vibration device 32 is started to drive the vibration table 310 to start vibrating. When the vibration table 310 vibrates, it will drive the contact table 39 and the top plate 38 to vibrate. When the top plate 38 vibrates, it will drive the sliding seat 37 to slide up and down slightly on the outer wall of the positioning rod 34, and then the sliding seat 37 compresses the movable spring 36. At the same time, under the elastic action of the movable spring 36, the sliding seat 37 is pushed to slide up and down continuously on the outer wall of the positioning rod 34. When the top plate 38 vibrates and moves up and down, it will drive the support table 41 to move synchronously, and then the support table 41 will drive the support seat 42 and The rotating shaft 43 and the containing frame 45 move, and the sample sand is also vibrated and shaken inside the containing frame 45. When the particle size of the sample sand is smaller than the screening hole of the screening plate 410, the sample sand with a small particle size continues to move downward, and is finally screened by several layers of screening plates 410. When the particle size of the sample sand is larger than the screening hole of the screening plate 410, the sample sand remains in the inner wall of the containing frame 45, and the sample sand with the smallest particle size remains on the receiving plate 411 in the bottom containing frame 45. When the screening of the sample sand is completed, the sample sands of different particle sizes are weighed, and the weighing device 27 is immediately started, and the corresponding containing frames 45 are driven to rotate from top to bottom in turn through the handle 46. The containing frame 4 5 drives the connecting seat 44 to rotate 90 degrees on the outer wall of the rotating shaft 43. When the receiving frame 45 rotates, it drives the magnet 1 47 to break away from the adsorption state with the magnet 2 49 and break away from the inner wall of the limiting frame 48. After the containing frame 45 rotates 90 degrees, the position of the screening plate 410 matches the receiving hopper 26, and then the right side of the screening plate 410 is rotated to drive the connecting shaft 414 to rotate in the inner wall of the receiving frame 45, and drive the sealing ring 413 to break away from the contact with the limiting ring 412, so that the screening plate 410 turns over and pours the sample sand downward onto the receiving hopper 26 and the weighing device 27 in the receiving frame 25. The sample sand of the particle size is weighed by the weighing device 27, and the data is fed back to the external controller. When the weighing is completed, the external controller sends the sample sand to the receiving hopper 26. The internal controller controls the electric push rod 211 to start working. The electric push rod 211 pushes the push plate 210 to break away from the contact with the receiving groove 28 and slide in the inner wall of the receiving frame 25, so that the push plate 210 pushes the weighed sample sand on the top wall of the weighing device 27 to the left. When pushing, it will drive the sealing seat 22 to start flipping and break away from the contact with the side wall of the receiving frame 25 and leak out the sand outlet 24, so that the sample sand can be smoothly discharged from the sand outlet 24 to the receiving frame 21 for unified collection. Repeating the above operation can weigh sample sands of different particle sizes, and the weighed data can be uniformly collected. The entire vibration, screening and weighing process of the sample sand is standardized. The structure of the entire device is not complicated, the operation is convenient, and it has a good use effect.
