Abstract
Description
Technical Field
[0001] This utility model relates to the field of sieve plate technology, specifically to a detachable sieve plate mud content testing device. Background Technology
[0002] When testing the mud content of coarse aggregates, different specifications require different sample quantities for mud content testing. For example, the test procedure for highway aggregates with a particle size of 31.5mm requires a sample quantity of more than 5kg, while the test procedure for concrete in waterway engineering requires a sample quantity of more than 10kg.
[0003] The existing detachable sieve mud content testing device requires manual washing of particles in water to separate dust, silt, and clay from coarser particles and suspend them in the water. This step is time-consuming and labor-intensive, and personnel may not be able to wash them thoroughly. In addition, when the device is tilted, coarse and fine particles are poured out together, which can damage the sieve surface. This makes it easy for coarse particles to be poured out during the test or for turbid liquid in the cylinder to not be completely emptied, increasing the number of washing cycles and wasting water resources. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a detachable sieve plate mud content testing device, which has the advantages of achieving mud volume through vibration washing and sieve plate disassembly and assembly, thus solving the problems mentioned in the background technology.
[0005] This utility model provides the following technical solution: a detachable sieve plate mud content testing device, including a base, a controller fixedly installed on the outer wall of the base, a motor fixedly installed on the top of the base, a drive wheel fixedly mounted on the power output shaft of the motor, a transmission belt tumblingly connected to the outer wall of the drive wheel, a driven wheel tumblingly connected to the outer wall of the transmission belt, a cam rod fixedly installed on the outer wall of the driven wheel, a fixing rod installed on the outer wall of the cam rod, a device body fixedly installed on the top of the fixing rod, a tension spring installed on the bottom of the device body, an inclined bottom block fixedly connected to the inner wall of the device body, a water outlet fixedly installed on the outer wall of the device body, a sieve plate body slidably connected to the inner wall of the device body, a second spring fixedly installed on the bottom of the sieve plate body, a limit block fixedly connected to one end of the second spring, a limit rod slidably sleeved on the inner wall of the device body, a pressure plate fixedly installed on the outer wall of the limit rod, a first spring movably sleeved on the outer wall of the limit rod, a sealing cover overlapping the top of the device body, and a round rod fixedly installed on the top of the base.
[0006] As a preferred technical solution of this utility model: the inner wall of the device is provided with a sliding groove, and the outer wall of the sliding groove is slidably connected with the outer wall of the limiting block.
[0007] As a preferred technical solution of this utility model: one end of the limiting rod is in contact with the outer wall of the limiting block, and one end of the first spring is fixed to the outer wall of the pressure plate.
[0008] As a preferred technical solution of this utility model: the motor and the controller are electrically connected, and the outer wall of the cam rod overlaps with the outer wall of the fixed rod.
[0009] As a preferred technical solution of this utility model: one end of the tension spring is fixed to the bottom of the device body, and the other end of the tension spring is fixed to the top of the base.
[0010] As a preferred technical solution of this utility model: the number of the round rods is four, and the outer walls of the four round rods are slidably sleeved with the outer wall of the object body.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] 1. This detachable sieve plate mud content testing device works by placing the sample on the device body, adding water, soaking for a specified time, and then sealing the cover. The controller uses a motor to drive the drive wheel, which in turn drives the driven wheel via a transmission belt. When the cam rod rotates, its thicker outer edge contacts the outer wall of the fixed rod, causing an impact. This impact compresses the tension spring. When the thinner outer edge of the cam rod disengages from the fixed rod, the tension spring resets. Repeated operation filters the mud and sand from the inner wall of the sieve plate, achieving vibration washing. After washing, the turbid liquid is immediately released from the bottom outlet. Clean water is added, and the above steps are repeated until clean water flows out. The inclined bottom block is designed to allow the turbid liquid and fine particles to drain.
[0013] 2. This detachable sieve plate mud content testing device, when pushed by external force, causes the limiting block to compress the second spring and slide on the outer wall of the chute. When it slides to the end, the elastic force of the second spring pushes the limiting block to engage with the inner wall of the device, so that the sieve plate is stably installed on the inner wall of the device. When pushed by external force, the limiting rod causes the first spring to abut and compress, so that the limiting rod pushes the limiting block. The limiting block, through the second spring, causes the sieve plate to detach from the inner wall of the device. When pulled by external force, the sieve plate causes the limiting block to slide on the outer wall of the chute, thus realizing disassembly and assembly. Attached Figure Description

Detailed Implementation
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0021] Please see Figure 1 - Figure 5 A detachable sieve plate mud content testing device includes a base 1, a controller 2 fixedly mounted on the outer wall of the base 1, a motor 4 fixedly mounted on the top of the base 1, a drive wheel 3 fixedly mounted on the power output shaft of the motor 4, a transmission belt 5 rollingly connected to the outer wall of the drive wheel 3, a driven wheel 7 rollingly connected to the outer wall of the transmission belt 5, a cam rod 6 fixedly mounted on the outer wall of the driven wheel 7, a fixing rod 21 mounted on the outer wall of the cam rod 6, a device body 10 fixedly mounted on the top of the fixing rod 21, and a tension spring 8 mounted on the bottom of the device body 10. An inclined bottom block 20 is fixedly connected to the inner wall of the vessel body 10. An outlet 14 is fixedly installed on the outer wall of the vessel body 10. A screen plate 11 is slidably connected to the inner wall of the vessel body 10. A second spring 18 is fixedly installed at the bottom of the screen plate 11. A limit block 17 is fixedly connected to one end of the second spring 18. A limit rod 12 is slidably sleeved on the inner wall of the vessel body 10. A pressure plate 15 is fixedly installed on the outer wall of the limit rod 12. A first spring 16 is movably sleeved on the outer wall of the limit rod 12. A sealing cover 13 overlaps the top of the vessel body 10. A round rod 9 is fixedly installed on the top of the base 1.
[0022] In the above structure, by installing the sealing cover 13, the amount of mud on the inner wall is covered and sealed to prevent mud and water from flowing out during vibration.
[0023] In a preferred embodiment, the inner wall of the device body 10 is provided with a sliding groove 19, and the outer wall of the sliding groove 19 is slidably connected to the outer wall of the limiting block 17.
[0024] In the above structure, the screen plate 11 is pushed by an external force, and the limiting block 17 drives the second spring 18 to slide on the outer wall of the slide groove 19. When it slides to the end, the elastic force of the second spring 18 pushes the limiting block 17 to engage with the inner wall of the device body 10, so that the screen plate 11 and the inner wall of the device body 10 are stably installed.
[0025] In a preferred embodiment: one end of the limiting rod 12 is in contact with the outer wall of the limiting block 17, and one end of the first spring 16 is fixed to the outer wall of the pressure plate 15.
[0026] In the above structure, the limiting rod 12 is pushed by an external force, and the limiting rod 12 drives the first spring 16 to abut against it, forming compression. This causes the limiting rod 12 to push the limiting block 17. The limiting block 17 drives the screen plate body 11 to detach from the inner wall of the device body 10 through the second spring 18. The screen plate body 11 is pulled by an external force, causing the screen plate body 11 to drive the limiting block 17 to slide on the outer wall of the slide groove 19, thus realizing disassembly and assembly.
[0027] In a preferred embodiment: the motor 4 and the controller 2 are electrically connected, and the outer wall of the cam rod 6 overlaps with the outer wall of the fixed rod 21.
[0028] In the above structure, the motor 4 drives the drive wheel 3 to rotate by the control controller 2. The drive wheel 3 drives the driven wheel 7 to rotate through the transmission belt 5. When the cam rod 6 rotates, the thicker outer edge contacts the outer wall of the fixed rod 21 and causes an impact, thereby causing the mud on the inner wall of the vessel 10 to be vibrated and washed.
[0029] In a preferred embodiment, one end of the tension spring 8 is fixed to the bottom of the body 10, and the other end of the tension spring 8 is fixed to the top of the base 1.
[0030] In the above structure, when the cam rod 6 rotates and collides with the fixed rod 21, the device body 10 drives the tension spring 8 to compress. When the thinner outer edge of the cam rod 6 separates from the fixed rod 21, the tension spring 8 resets. Repeated operation allows the mud and sand to be filtered from the inner wall of the screen plate body 11, making the screening more obvious and saving screening time.
[0031] In a preferred embodiment, there are four round rods 9, and the outer walls of the four round rods 9 are slidably connected to the outer wall of the body 10.
[0032] In the above structure, the outer walls of the four round rods 9 are slidably connected to the outer wall of the device body 10. When the device body 10 drives the screen plate body 11 to vibrate and screen, the device body 10 slides on the outer wall of the round rods 9, so that the vibration of the device body 10 is stably limited and avoids derailment.
[0033] Working principle: During the coarse aggregate mud content test, the screen plate 11 is pushed by external force, and the limiting block 17 drives the second spring 18 to slide against the outer wall of the slide groove 19. When it slides to the end, the elastic force of the second spring 18 pushes the limiting block 17 to engage with the inner wall of the container 10, so that the screen plate 11 and the inner wall of the container 10 are stably installed. After the sample is placed on the container 10, water is added and soaked for a specified time. The sealing cover 13 is then covered. The controller 2 is used to drive the drive wheel 3 to rotate via the motor 4. The drive wheel 3 drives the driven wheel 7 to rotate via the transmission belt 5. When the cam rod 6 rotates, the thicker outer edge contacts the outer wall of the fixed rod 21, causing an impact. This vibrates and washes the mud on the inner wall of the container 10. Immediately afterward, the turbid liquid is discharged from the bottom outlet 14. Clean water is added and the above steps are repeated until clean water flows out. The discharged water is collected and passed through a 0.075mm sieve to remove the underflow solution. The particles on the sieve and the material in the cylinder are poured into a square pan for drying and weighing. The limiting rod 12 is pushed by external force, and the limiting rod 12 drives the first spring 16 to abut against each other, forming compression. This causes the limiting rod 12 to push the limiting block 17. The limiting block 17 drives the sieve plate 11 to detach from the inner wall of the container 10 through the second spring 18. The sieve plate 11 is pulled by external force, causing the sieve plate 11 to drive the limiting block 17 to slide on the outer wall of the slide groove 19, realizing disassembly and assembly. This is to check whether there are fine particles remaining on the inner wall of the container 10. The inclined bottom block 20 is made into an inclined surface to allow the turbid liquid and fine particles to be discharged.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
