However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0019] This application embodiment provides an online intelligent spiral sampling device for machine-made sand, please refer to Figure 1-Figure 8: It includes a sampling tube body 1, a fixing plate 2 is installed at the end of the sampling tube body 1, a motor protection box 3 is installed on the fixing plate 2, a spiral conveying mechanism is provided on the sampling tube body 1, and a sampling screening mechanism is provided on the sampling tube body 1; The spiral conveying mechanism includes a drill bit 4, a driving motor 5, a rotating shaft 6 and an intermittent conveying part 7. The drill bit 4 is rotatably connected to the front end of the sampling barrel body 1. The driving motor 5 is installed in the motor protection box 3. The rotating shaft 6 is rotatably connected in the sampling barrel body 1. One end of the rotating shaft 6 is fixedly connected to the output end of the driving motor 5, and the other end of the rotating shaft 6 is fixedly connected to the drill bit 4. The intermittent conveying part 7 intermittently conveys the machine-made sand. The sampling and screening mechanism includes a discharge pipe 8, a lifting part 9, a screening part 10 and a vibration part 11. The discharge pipe 8 is connected to one side of the bottom of the sampling tube body 1. The screening part 10 screens the machine-made sand according to size, and the vibration part 11 vibrates the screening part 10 to facilitate the machine-made sand to pass through the screening part 10.

[0020] Specifically in practical applications, when sampling, the driving motor 5 starts to work, and the output end of the driving motor 5 drives the drill bit 4 to rotate through the rotating shaft 6, so that the drill bit 4 is in contact with the bag of machine-made sand or the pile of sand and gravel, and the drill bit 4 and the sampling tube body 1 are inserted into the bag or the pile of sand and gravel, and the machine-made sand is intermittently conveyed by the intermittent conveying part 7, and the machine-made sand falls into the discharge pipe 8. The machine-made sand is screened according to size by the screening part 10, and the vibration part 11 vibrates the screening part 10 to facilitate the machine-made sand to pass through the screening part 10.

[0021] Refer to the instruction manual Figure 1 , Instruction Manual Figure 2 And the instruction manual Figure 3 The intermittent conveying part 7 includes a spiral conveying blade 12 installed on the rotating shaft 6, the end of the spiral conveying blade 12 is located above the discharge pipe 8, a feed port 13 is provided above the front end of the sampling tube body 1, the drill bit 4 is a hollow structure, the drill bit 4 is mounted on the front end of the sampling tube body 1, an opening 14 is provided on the drill bit 4, the size of the opening 14 is consistent with the feed port 13, and a spiral convex strip 15 is installed on the outer periphery of the drill bit 4.

[0022] Specifically in actual applications, the output end of the driving motor 5 drives the drill bit 4 to rotate through the rotating shaft 6, and the spiral ribs 15 on the drill bit 4 rotate together, and the machine-made sand is transported through the spiral ribs 15, and the machine-made sand is transported toward the opening 14. When the opening 14 on the drill bit 4 coincides with the feed port 13 on the sampling barrel main body 1, the machine-made sand enters the sampling barrel main body 1 through the opening 14 and the feed port 13, and the rotating shaft 6 drives the spiral conveying blade 12 to rotate to convey the machine-made sand. When the opening 14 on the drill bit 4 is staggered with the feed port 13 on the sampling barrel main body 1, the machine-made sand cannot enter the sampling barrel main body 1, and the machine-made sand enters the sampling barrel main body 1 intermittently, so as to avoid excessive machine-made sand entering at the same time, avoid the spiral conveying blade 12 from getting stuck, and avoid the phenomenon of material blockage.

[0023] Refer to the instruction manual Figure 1 And the instruction manual Figure 2 The lifting part 9 includes a fixed support plate 16 installed at the bottom of the sampling tube body 1, the fixed support plate 16 is located on one side of the discharge pipe 8, a multi-stage telescopic cylinder 17 is installed at the bottom of the fixed support plate 16, a connecting support rod 18 is installed on the telescopic end of the multi-stage telescopic cylinder 17, a bearing base plate 19 is installed at one end of the connecting support rod 18 away from the multi-stage telescopic cylinder 17, a first weighing sensor 20 is installed on the bearing base plate 19, a weighing plate 21 is installed on the first weighing sensor 20, a placement groove 22 is provided on the surface of the weighing plate 21, and a sampling bottle 23 is placed in the placement groove 22.

[0024] Specifically in actual application, the sampling bottle 23 is placed in the placement groove 22 on the surface of the weighing plate 21, and the multi-stage telescopic cylinder 17 is started. The telescopic end of the multi-stage telescopic cylinder 17 contracts and drives the supporting base plate 19 to move upward through the connecting support rod 18. The supporting base plate 19 drives the weighing plate 21 and the sampling bottle 23 to rise. When the machine-made sand is transported to the end of the sampling tube body 1, it enters the sampling bottle 23 through the discharge pipe 8, and the machine-made sand in the sampling bottle 23 is weighed by the weighing plate 21.

[0025] Refer to the instruction manual Figure 2 , Instruction Manual Figure 4 And the instruction manual Figure 5The screening part 10 includes a lifting sleeve 24 which is sleeved on the discharge pipe 8, a power push rod 25 is installed on the fixed support plate 16, a connecting rod 26 is installed on the telescopic end of the power push rod 25, one end of the connecting rod 26 is fixedly connected to the lifting sleeve 24, connecting support plates 48 are installed on both sides of the lifting sleeve 24, a second weighing sensor 27 is installed on the connecting support plate 48, a connecting ring plate 28 is installed on the detection end of the second weighing sensor 27, the connecting ring plate 28 is slidably connected to the inner wall of the discharge pipe 8, a movable ring plate 29 is provided in the discharge pipe 8, and a movable ring plate 29 is provided between the movable ring plate 29 and the connecting ring plate 28 A telescopic spring 30 is connected, a flip filter screen 31 is rotatably connected in the movable ring plate 29, a vertical slide groove 32 is provided on one side of the discharge pipe 8, a lifting slider 33 is slidably connected in the vertical slide groove 32, an oblique support rod 34 is installed on one side of the lifting slider 33, and the oblique support rod 34 is fixedly connected to the movable ring plate 29 at one end away from the lifting slider 33, a motor fixing plate 35 is installed on the lifting slider 33, a rotating motor 36 is installed on the motor fixing plate 35, a rotating shaft 37 is installed on the output end of the rotating motor 36, and the rotating shaft 37 is fixedly connected to the flip filter screen 31 at one end away from the rotating motor 36.

[0026] Specifically in practical applications, the machine-made sand is conveyed into the discharge pipe 8, and the machine-made sand falls on the movable ring plate 29 and the flip filter screen 31. The machine-made sand is screened by the flip filter screen 31, and the qualified machine-made sand passes through the filter holes on the flip filter screen 31 and enters the sampling bottle 23 through the lifting sleeve 24, and the unqualified machine-made sand remains on the flip filter screen 31. In the process of the machine-made sand falling, the machine-made sand is guided by the connecting ring plate 28 to prevent the machine-made sand from being stuck in the discharge pipe 8 and the lifting sleeve 24 and unable to fall, thereby improving the feeding efficiency. When the machine-made sand falls on the movable ring plate 29 and the flip filter screen 31, an impact force is applied to the movable ring plate 29 and the flip filter screen 31, and pressure is applied to the telescopic spring 30. The telescopic spring 30 is deformed and contracted after being subjected to pressure, so that the movable ring plate 29 and the flip filter screen 31 can vibrate up and down, thereby improving the feeding efficiency of the machine-made sand passing through the flip filter screen 31. The second weighing sensor 27 can detect the weight of the machine-made sand on the flip filter screen 31. When the weight exceeds the set value, it proves that the amount of machine-made sand is too large, and the power push rod 25 starts to work. The telescopic end of the power push rod 25 extends into the connecting rod 26 to drive the lifting sleeve 24 to descend along the discharge pipe 8, thereby increasing the volume for holding the machine-made sand and avoiding clogging of the sampling tube body 1. After the sampling is completed, the qualified machine-made sand is first collected in the sampling bottle 23, and the weight of the qualified machine-made sand is first weighed by the first weighing sensor 20. After the weighing is completed, the rotating motor 36 starts to work, and the output end of the rotating motor 36 drives the flip filter 31 to flip through the rotating shaft 37, so that the unqualified machine-made sand on the flip filter 31 falls, and the unqualified machine-made sand falls into the sampling bottle 23. The weight of the unqualified machine-made sand and the weight of all the machine-made sand can be weighed to obtain the parameters of the machine-made sand. The machine-made sand can be tested during the sampling process, and there is no need to test the machine-made sand after sampling, thereby ensuring the quality of the machine-made sand, improving work efficiency, and reducing manual labor intensity.

[0027] Refer to the instruction manual Figure 2 , Instruction Manual Figure 6 And the instruction manual Figure 8 The vibration part 11 includes an eccentric wheel 38 installed on the rotating shaft 6, and the eccentric wheel 38 is located at the end of the spiral conveying blade 12. A fixed block 39 is installed on one side of the surface of the movable ring plate 29, and a telescopic cylinder 40 is installed on the fixed block 39. A reinforcing rod 41 is installed on the telescopic end of the telescopic cylinder 40. An arc-shaped top plate 42 is installed on the top of the reinforcing rod 41. An arc-shaped groove 43 is provided on the surface of the arc-shaped top plate 42. A plurality of roller shafts 44 are rotatably connected in the arc-shaped groove 43, and the roller shafts 44 are in contact with the eccentric wheel 38.

[0028] Specifically in practical applications, the eccentric wheel 38 is driven to rotate while the rotating shaft 6 rotates. When the eccentric wheel 38 contacts the roller shaft 44 on the arc-shaped top plate 42, the reinforcing rod 41 can be squeezed downward. The reinforcing rod 41 applies force to the movable ring plate 29 through the telescopic cylinder 40 and the fixed block 39. The movable ring plate 29 applies pressure to the telescopic spring 30. The telescopic spring 30 deforms and contracts after being subjected to pressure, so that the movable ring plate 29 and the flip filter screen 31 can vibrate up and down, thereby improving the feeding efficiency of the machine-made sand passing through the flip filter screen 31 and avoiding the machine-made sand from being blocked on the flip filter screen 31. When the lifting sleeve 24 descends, the telescopic cylinder 40 starts to work, and the telescopic end of the telescopic cylinder 40 extends into and drives the arc-shaped top plate 42 to rise. The distance between the arc-shaped top plate 42 and the eccentric wheel 38 is always consistent, so that the flip filter screen 31 can always vibrate up and down. The eccentric wheel 38 contacts the roller shaft 44 during rotation, and the roller shaft 44 can rotate in the arc-shaped groove 43, thereby reducing wear and increasing service life.

[0029] Refer to the instruction manual Figure 2 The diameter of the placement groove 22 is the same as the size of the sampling bottle 23, and the mouth of the sampling bottle 23 is inserted into the bottom of the lifting sleeve 24. Specifically in practical applications, when machine-made sand is being unloaded, the mouth of the sampling bottle 23 is inserted into the bottom of the lifting sleeve 24 to prevent the machine-made sand from spilling outside. During weighing, the telescopic end of the multi-stage telescopic cylinder 17 extends in to lower the weighing plate 21 and the sampling bottle 23, so that the sampling bottle 23 does not contact the lifting sleeve 24, thereby avoiding affecting the weighing accuracy.

[0030] Refer to the instruction manual Figure 4 And the instruction manual Figure 5 The inner and outer diameters of the connecting ring plate 28 and the movable ring plate 29 are the same, and the inner circles of the connecting ring plate 28 and the movable ring plate 29 are inclined downward.

[0031] Specifically in practical applications, the inner circle connecting the ring plate 28 and the movable ring plate 29 is tilted downward, which can guide the machine-made sand to prevent the machine-made sand from being stuck in the discharge pipe 8 and the lifting sleeve 24 and unable to fall, thereby improving the discharge efficiency.

[0032] Refer to the instruction manual Figure 6 A guide ring 45 is mounted on the reinforcing rod 41 , and an oblique support rod 46 is installed on one side of the guide ring 45 . One end of the oblique support rod 46 away from the guide ring 45 is fixedly connected to the inner wall of the discharge pipe 8 .

[0033] Specifically in practical applications, when the reinforcing rod 41 moves up and down, the reinforcing rod 41 is guided by the guide ring 45, and the reinforcing rod 41 moves up and down along the guide ring 45, thereby preventing the reinforcing rod 41 from bending and deforming, thereby increasing the service life.

[0034] Refer to the instruction manual Figure 1And the instruction manual Figure 2 A lifting handle 47 is installed on the sampling tube body 1 and the motor protection box 3.

[0035] Specifically in practical applications, the lifting handle 47 is convenient for holding and sampling of machine-made sand.
