UTILITY MODEL CONTENTS

[0004] The existing screw rod sampler in actual use, screw rod sampler is generally horizontally arranged, in the sampling process, due to the residual material accumulated in the pipeline previously not being cleaned in time, it will cause the subsequent material taking cannot take the freshest material sample, at the same time, when connecting the sampling tube and the connecting pipe to the fixed pipe and the collecting pipe, since both sides need to be fixed using bolts, it needs to spend a lot of time, therefore, it is necessary to realize the optimization of a kind of screw rod sampler for ton bag sampling through technical innovation and design optimization.

[0005] The technical scheme adopted by the embodiment of the present application to solve its technical problems is:

[0006] A kind of screw rod sampler for ton bag sampling, comprising:

[0007] The blanking pipe is communicated with the inlet pipe on one side, the fixed pipe is fixed on the blanking pipe, the sampling mechanism is arranged on one side of the fixed pipe, and the material in the blanking pipe is sampled.

[0008] A collecting pipe is arranged at the bottom of the sampling mechanism, and a limiting mechanism is arranged between the collecting pipe and the sampling mechanism for quickly connecting the collecting pipe with the sampling mechanism.

[0009] In a possible implementation, the fixed pipe is arranged below the feeding pipe, the feeding pipe is provided with a gap, and the discharging end of the feeding pipe is located directly above the gap, so that the material can directly fall from the discharging end of the feeding pipe to the gap on the fixed pipe.

[0010] In a possible implementation, the fixed pipe is arranged to be inclined, and the inner end of the fixed pipe is arranged to be lower than the other end, so that the material falling into the fixed pipe can freely slide into the inner part of the feeding pipe.

[0011] In a possible implementation, the sampling mechanism comprises a sampling pipe arranged on one side of the fixed pipe, a screw rod is arranged in the sampling pipe, a motor is fixed at the end of the sampling pipe away from the fixed pipe, the output end of the motor penetrates the sampling pipe and is fixedly connected with the screw rod, and the bottom of the sampling pipe is connected with a connecting pipe. Generally, the motor is controlled to rotate in the forward direction, and the residual material in the fixed pipe is sent out of the fixed pipe by the screw rod. When sampling is needed, the motor is controlled to rotate in the reverse direction, the motor drives the screw rod to rotate, the screw rod drives the material falling into the fixed pipe upwards, and the material falls into the collecting pipe from the connecting pipe.

[0012] In a possible implementation, the fixed pipe and the sampling pipe are fixed by bolts at the end close to each other, so as to fix the fixed pipe and the sampling pipe.

[0013] In a possible implementation, the limiting mechanism comprises a fixed plate fixed on the collecting pipe, a slot is arranged on the fixed plate, a plug ring is fixed on the connecting pipe, the plug ring can be inserted into the slot, a fixed ring is fixed on the top of the fixed plate, and a ring is arranged on the connecting pipe. An annular groove is arranged at the bottom of the ring, the plug ring at the bottom of the connecting pipe is inserted into the slot at the top of the fixed plate, and then the ring is rotated, so that the threaded groove at the bottom of the ring is threadedly connected with the fixed ring, thereby quickly fixing the connecting pipe and the collecting pipe.

[0014] In a possible implementation, the ring can slide on the connecting pipe, the fixed ring is matched with the annular groove, and the annular groove is threadedly connected with the fixed ring, so as to fix the ring and the fixed ring.

[0015] In a possible implementation, a rotating ring is arranged at the top of the ring outside the connecting pipe, the rotating ring is threadedly connected with the connecting pipe, the rotating ring is rotated to tightly abut against the ring, and the ring is limited.

[0016] In summary, the utility model has at least one of the following beneficial technical effects:

[0017] 1. Since both the fixed tube and the sampling tube are set at an angle, the material will be discharged from the end of the fixed tube. When the motor rotates forward, the screw will discharge the remaining material in the fixed tube and the sampling tube from the end of the fixed tube. When the motor rotates in reverse, the screw will lift the material that has fallen into the fixed tube from the notch to the connecting tube, and then fall from the connecting tube into the collection tube. This avoids picking up the material that was left over before, and ensures that the material picked up each time is fresh.

[0018] 2. By aligning the sampling tube with the fixed tube and fixing it with bolts, the insertion ring at the bottom of the connecting tube is inserted into the groove at the top of the fixed plate. Then, rotate the ring so that the threaded groove at the bottom of the ring is threadedly connected to the fixed ring. Then rotate the rotating ring so that the rotating ring is tightly attached to the ring, which facilitates the limiting of the ring, thereby quickly fixing the connecting tube and the collection tube.

[0026] The blanking pipe 2 is communicated with the feeding pipe 1 on one side, and the fixed pipe 3 is fixed on the blanking pipe 2; the fixed pipe 3 is provided with a sampling mechanism on one side, which is used for sampling the material in the blanking pipe 2.

[0027] The collecting pipe 8 is located at the bottom of the sampling mechanism, and the limiting mechanism is arranged between the collecting pipe 8 and the sampling mechanism, which is used for quickly communicating the collecting pipe 8 with the sampling mechanism.

[0028] In actual use, the material often needs to be sampled. The previous electric screw sampler is horizontally arranged, and in the sampling process, due to the accumulation of residual material in the pipeline in advance, the freshest material sample cannot be taken every time.

[0029] The fixed pipe 3 is located below the feeding pipe 1, and the notch 10 is arranged on the feeding pipe 1; the discharging end of the feeding pipe 1 is located directly above the notch 10, so that the material can directly fall from the discharging end of the feeding pipe 1 to the notch 10 on the fixed pipe 3; the fixed pipe 3 is arranged in an inclined manner, and one end of the fixed pipe 3 located inside the blanking pipe 2 is lower than the other end, so that the material falling into the fixed pipe 3 can freely slide into the blanking pipe 2; the sampling mechanism includes the sampling pipe 4 located on one side of the fixed pipe 3; the sampling pipe 4 is internally provided with the screw rod 11; the motor 5 is fixed on the end of the sampling pipe 4 away from the fixed pipe 3; the output end of the motor 5 penetrates through the sampling pipe 4 and is fixedly connected with the screw rod 11; the sampling pipe 4 is communicated with the connecting pipe 6 at the bottom; in general, the motor 5 is controlled to rotate forward, and the residual material in the fixed pipe 3 will be sent out of the fixed pipe 3 by the screw rod 11; when sampling is needed, the motor 5 is controlled to reverse, and the motor 5 drives the screw rod 11 to rotate, so that the material falling into the fixed pipe 3 is driven upward by the screw rod 11 until it falls into the collecting pipe 8; the end of the fixed pipe 3 and the sampling pipe 4 close to each other can be fixed by bolts, so as to fix the fixed pipe 3 and the sampling pipe 4.

[0030] When the sampling pipe 4 and the connecting pipe 6 are connected to the fixed pipe 3 and the collecting pipe 8, the bolts need to be used on both sides, which consumes a lot of time.

[0031] The limiting mechanism comprises a fixed plate 9 fixed on the collecting pipe 8, a notch 13 is formed on the fixed plate 9, a connecting pipe 6 is fixed with an inserting ring 14, the inserting ring 14 can be inserted into the notch 13, a fixed ring 12 is fixed on the top of the fixed plate 9, a circular ring 7 is sleeved on the connecting pipe 6, a ring-shaped groove 15 is formed on the bottom of the circular ring 7, the inserting ring 14 at the bottom of the connecting pipe 6 is inserted into the notch 13 at the top of the fixed plate 9, then the circular ring 7 is rotated, so that the threaded groove at the bottom of the circular ring 7 is screwed with the fixed ring 12, thereby the connecting pipe 6 and the collecting pipe 8 are quickly fixed, the circular ring 7 can slide on the connecting pipe 6, the fixed ring 12 is matched with the ring-shaped groove 15, the ring-shaped groove 15 is screwed with the fixed ring 12, thereby the circular ring 7 and the fixed ring 12 are fixed, a rotating ring 16 is arranged on the top of the circular ring 7 outside the connecting pipe 6, the rotating ring 16 is screwed with the connecting pipe 6, the rotating ring 16 is rotated, so that the rotating ring 16 is tightly attached to the circular ring 7, thereby the circular ring 7 is limited.

[0032] Under normal working condition, the motor 5 rotates normally, the feeding pipe 1 discharges the material into the notch 10 on the fixed pipe 3, since the fixed pipe 3 and the sampling pipe 4 are both arranged in an inclined manner, the material is discharged from the end of the fixed pipe 3, the screw rod 11 discharges the remaining material in the fixed pipe 3 and the sampling pipe 4 from the end of the fixed pipe 3, when the worker needs to take sample, the motor 5 is reversely started, the screw rod 11 lifts the material falling into the fixed pipe 3 from the notch 10 to the connecting pipe 6, then the material falls into the collecting pipe 8, thereby the material taken is fresh.

[0033] When the sampling pipe 4 and the connecting pipe 6 are installed, the sampling pipe 4 is aligned with the fixed pipe 3 and is fixed by bolts, at this time, the inserting ring 14 at the bottom of the connecting pipe 6 is inserted into the notch 13 at the top of the fixed plate 9, then the circular ring 7 is rotated, so that the threaded groove at the bottom of the circular ring 7 is screwed with the fixed ring 12, thereby the connecting pipe 6 and the collecting pipe 8 are quickly fixed, then the rotating ring 16 is rotated, so that the rotating ring 16 is tightly attached to the circular ring 7, thereby the circular ring 7 is limited.
