Detailed implementation manners

[0030] For better explaining the present utility model for easy understanding, the present utility model will be described in detail below in conjunction with the drawings through specific implementation manners.

[0031] Please refer to Figures 1 to 6 As shown, a sand powder sample storage rack of the present utility model includes a storage box 2, a feeding mechanism 6, a placement mechanism 1 and an elimination mechanism 3. The placement mechanism 1 is arranged inside the storage box 2. The feeding mechanism 6 is arranged on one side of the placement mechanism 1, and the elimination mechanism 3 is arranged on the other side of the placement mechanism 1. Both the feeding mechanism 6 and the elimination mechanism 3 are connected to the storage box 2;

[0032] The placement mechanism 1 includes a tipping and lifting assembly and a plurality of placement plates 106. Inside the storage box 2, a plurality of the placement plates 106 are arranged from top to bottom. The middle parts of the placement plates 106 are rotatably connected to the storage box 2. One side of each placement plate 106 is connected to the tipping and lifting assembly. Feeding ports are arranged at one ends of the storage box 2 close to the placement plates 106. The feeding mechanism 6 is movably connected to the feeding ports. Discharge ports are arranged at the other ends of the storage box 2 close to the placement plates 106. One elimination mechanism 3 is arranged inside each discharge port;

[0033] A sampling port is arranged on one side of the storage box 2, and a door panel 4 is hinged on the sampling port.

[0034] The working principle of the present utility model is as follows: During actual production and use, when it is necessary to store samples of raw materials and finished products, the taken samples can be placed one by one in the sample storage tank 10. When it is necessary to place the sample storage tank 10 on the storage rack, the sample storage tank 10 can be placed on the feeding mechanism 6. Then, the feeding mechanism 6 is operated to lift the sample storage tank 10 to the corresponding type of storage placement plate 106. Then, the sample storage tank 10 enters the placement plate 106 through the feeding port for storage. When it is necessary to eliminate samples arranged at the rear or with a longer aging time on the placement plate 106, the elimination mechanism 3 at the position of the sample to be eliminated can be operated to open the elimination mechanism 3. Then, the tipping and lifting assembly is operated to drive the placement plate 106 to tip towards the discharge port. Then, the sample storage tank 10 at the rearmost end of the placement plate 106 enters the elimination mechanism 3. Then, the placement plate 106 is reset. When it is necessary to conduct spot checks on the samples, the door panel 4 can be rotated to open the sampling port. Then, the sample storage tank 10 where the sample is located is taken.

[0035] Further, the tipping and lifting assembly includes a first bracket 103, a first rotation driving member 102, a first screw 101, a lifting block 104, and a connecting rod 105. The connecting rod 105 is arranged on one side of the storage box 2 close to the feeding port and is slidably connected to the storage box 2. One side of each placement plate 106 close to the feeding port is rotatably connected to the connecting rod 105. The first bracket 103 is arranged on the top of the storage box 2. The lifting block 104 is arranged at the top of the connecting rod 105. The first screw 101 passes through the middle of the lifting block 104 and is rotatably connected to the first bracket 103. The first rotation driving member 102 is drivingly connected to the first screw 101.

[0036] As can be seen from the above description, when it is necessary to discard the sample in the sample storage tank 10 at the end of the placement plate 106, the elimination mechanism 3 at the required sample storage tank 10 to be discarded can be activated. Subsequently, the first rotation driving member 102 is operated to drive the first screw rod 101 to rotate by the first rotation driving member 102. Thus, the first screw rod 101 drives the connecting rod 105 to move upward through the lifting block 104, so that the placement plate 106 can be tilted toward the discharge port, and the sample storage tank 10 to be discarded rolls into the elimination mechanism 3. Subsequently, the placement plate 106 is reset.

[0037] Further, the feeding mechanism 6 includes a feeding bin 605, a lifting assembly, a bearing plate 604, and a pushing assembly. The feeding bin 605 is arranged on one side of the storage box 2 close to the feeding port. A sample inlet is arranged at the lower part of the feeding bin 605. The bearing plate 604 is slidably connected to the inside of the feeding bin 605. The pushing assembly is arranged on the upper part of the bearing plate 604. The lifting assembly is drivingly connected to the bearing plate 604. The feeding ports are all communicated with the feeding bin 605.

[0038] As can be seen from the above description, when it is necessary to store the sample on the corresponding placement plate 106, the sample storage tank 10 can be pre-placed on the pushing assembly through the sample inlet. Subsequently, the lifting assembly is operated to drive the sample storage tank 10 to move to the required storage height through the bearing plate 604. Subsequently, the pushing assembly is operated to enable the sample storage tank 10 to better enter the placement plate 106 from the feeding port for storage.

[0039] Further, the lifting assembly includes a second rotation driving member 601, a second screw rod 602, and a slider 603. A chute is arranged on one side of the feeding bin 605 away from the storage box 2. One side of the slider 603 is slidably connected to the chute. The other side of the slider 603 is connected to the bearing plate 604. The second screw rod 602 passes through the middle of the slider 603 and is rotatably connected to the outside of the feeding bin 605. The second rotation driving member 601 is drivingly connected to the second screw rod 602.

[0040] As can be seen from the above description, when it is necessary to store the sample, the second rotation driving member 601 can be operated to drive the second screw rod 602 to rotate, so that the second screw rod 602 drives the bearing plate 604 to move through the slider 603, enabling the sample to better move to an appropriate height.

[0041] Further, the pushing assembly includes a linear driving member 607 and a top plate 606. One end of the top plate 606 is rotatably connected to one side of the bearing plate 604 close to the feeding port. The linear driving member 607 is drivingly connected to the other end of the top plate 606.

[0042] As can be seen from the above description, when it is necessary to place the sample storage tank 10 on the placement plate 106, the sample storage tank 10 can first be lifted to the required placement height by the lifting assembly, and then the linear drive 607 is operated to drive the other end of the top plate 606 to rise, causing the top plate 606 to tilt towards the feed port, so that the sample storage tank 10 on the top plate 606 can roll better onto the placement plate 106.

[0043] Further, the elimination mechanism 3 includes a third rotation drive 301 and a discharge cylinder 303. The discharge cylinder 303 is rotatably connected to the inside of the discharge port. The third rotation drive 301 is rotationally drivingly connected to the discharge cylinder 303, and a discharge port 302 is provided on the discharge cylinder 303.

[0044] As can be seen from the above description, when it is necessary to eliminate the sample storage tank 10 at the very end of the placement plate 106, the third rotation drive 301 can be operated to drive the discharge cylinder 303 to rotate, causing the discharge port 302 to open towards the placement plate 106. Then the placement plate 106 tilts, so that the sample storage tank 10 at the very end of the placement plate 106 rolls into the discharge cylinder 303. Subsequently, the discharge cylinder 303 continues to rotate, causing the opening of the discharge port 302 to move out of the direction of the placement plate 106, and then the placement plate 106 is reset.

[0045] Further, it further includes a waste storage bin, which is arranged at the bottom of the storage box 2, and the waste storage bin is communicated with the discharge port 302 through a discharge bin 8.

[0046] As can be seen from the above description, it is beneficial that the sample storage tank 10 to be discarded in the discharge cylinder 303 can be made to fall into the waste storage bin for storage by continuing to rotate the discharge cylinder 303 to make the discharge port 302 on the discharge cylinder 303 rotate towards the discharge bin 8, which is convenient for subsequent centralized cleaning by the operator.

[0047] Further, a discharge port 9 is provided at the lower part of the waste storage bin 5.

[0048] As can be seen from the above description, it is beneficial for the operator to carry out centralized cleaning better subsequently.

[0049] Further, it further includes an occlusion component 7, which is connected to the feed inlet. The occlusion component 7 includes a second bracket 702, a fourth rotation driving member 701, a third screw 703, a moving plate 705, a movable member 704, and a baffle 706. A baffle 706 is movably connected inside each feed inlet. The baffles 706 are all connected to the moving plate 705. The movable member 704 is connected to the moving plate 705. The second bracket 702 is connected to the outer surface of the storage box 2. The third screw 703 passes through the middle of the movable member 704 and is rotatably connected to the second bracket 702. The fourth rotation driving member 701 is drivingly connected to the third screw 703.

[0050] As can be seen from the above description, it is beneficial that before the sample storage tank 10 is ready to be fed, the baffle 706 first occludes each feed inlet to prevent the sample storage tank 10 from slipping onto other placement plates 106 in advance. When the sample storage tank 10 reaches the required storage height, the fourth rotation driving member 701 can be operated to drive the third screw 703 to rotate by the fourth rotation driving member 701, so that the movable member 704 drives a plurality of baffles 706 to move through the moving plate 705. Subsequently, the feed inlet is opened to facilitate the storage tank to enter the feed inlet at this height.

[0051] Further, it further includes a PLC controller, which is electrically connected to the feeding mechanism 6, the placement mechanism 1, and the elimination mechanism 3 respectively.

[0052] As can be seen from the above description, it is beneficial to adjust the parameters of the sand powder sample storage rack through the PLC controller and make it more convenient for the operator to operate the sand powder sample storage rack.
