DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0022] Please refer to Figure 1 With Figure 2 The utility model provides a kind of technical scheme: a sampling clamp with lifting structure, it include: fixed seat 1 and hydraulic cylinder 6, the inside of fixed seat 1 is equipped with sliding block 2, the inside of sliding block 2 is connected with clamping block 3 by pivot, one end of clamping block 3 is connected with movable block 4 by sliding block, the bottom of movable block 4 is connected with connecting block 5, and hydraulic cylinder 6 is connected on one side of connecting block 5;

[0023] The middle of sliding block 2 is connected with lead screw 7, and the top of lead screw 7 is connected with drive motor 8 by shaft coupling and penetrates fixed seat 1, the bottom of sliding block 2 is equipped with fixed frame 9, and fixed frame 9 is slidably connected with support frame 10 in its inside, the top of support frame 10 is equipped with screw sleeve 11, the middle of screw sleeve 11 is connected with screw rod 12, the input end of screw rod 12 is connected with transmission motor 13 by shaft coupling, and lead screw 7 and sliding block 2 are screw connection.

[0024] In specific implementation, when the sampling clamp with the lifting structure needs to lift the sample, one end of the two sets of clamping blocks 3 is rotated to approach each other, so that the product to be sampled can be clamped, and then the driving motor 8 is started to drive the screw rod 7 to rotate through the coupling. Since the screw rod 7 is in threaded connection with the sliding block 2, and the sliding block 2 is slidingly connected to one side of the fixed seat 1, the screw rod 7 drives the sliding block 2 to slide when rotating. The sliding block 2 drives the entire clamping block 3 to move upward when sliding. At the same time, the transmission motor 13 is started to drive the screw rod 12 to rotate through the coupling. The screw sleeve 11 is sleeved on the outside of the screw rod 12 and slidingly connected in the groove at the bottom of the sliding block 2. The screw sleeve 11 is connected with the support frame 10 in the fixed frame 9. Therefore, when the screw rod 12 rotates, the support frame 10 is driven to slide along the fixed frame 9 through the screw sleeve 11, so that the support frame 10 slides to the bottom of the sample. At this time, the support frame 10 can lift the sample, so that the clamping block 3 does not damage the sample when clamping the sample, and the sample is not easy to fall off from the clamp.

[0025] Referring to Figures 1-3 It can be known that, in use, the driving motor 8 can be started according to the use requirement to drive the clamping block 3 to move upward through the screw rod 7 and the sliding block 2, and the screw sleeve 11 drives the support frame 10 to slide out of the fixed frame 9 and move to the bottom of the sample through the transmission motor 13 and the screw rod 12. At this time, the support frame 10 can lift the sample, so that the sample is not easy to fall off, and the clamp can be appropriately loosened to avoid damage to the sample.

[0026] The clamping block 3 is connected with the wedge block 14 on one side. The wedge block 14 is connected with the guide rod 15 penetrating the clamping block 3 on one side. The guide rod 15 is connected with the threaded rod 16 penetrating on one side. The guide rod 15 and the sliding groove of the clamping block 3 form a sliding structure. The threaded rod 16 is in threaded connection with the guide rod 15. The limiting block 17 penetrating the guide rod 15 is connected with the gear rack 18 connected between the sliding groove of the clamping block 3 and the limiting block 17 on one side of the threaded rod 16 through the bearing. The gear rack 18 is symmetrically installed on the inner wall of the sliding groove of the clamping block 3.

[0027] In specific implementation, when the sampling clamp with the lifting structure needs to adjust the clamping position of the sample, only the threaded rod 16 needs to be rotated. Since the threaded rod 16 is in threaded connection with the guide rod 15, and the other end of the threaded rod 16 is connected with the limiting block 17 penetrating the groove of the guide rod 15 through a bearing, at this time, the threaded rod 16 will drive the limiting block 17 to shrink along the guide rod 15 to the inside of the clamping block 3, so that the limiting block 17 is separated from the rack 18 in the groove of the clamping block 3. Without the limiting action of the limiting block 17 and the rack 18 on the guide rod 15, the guide rod 15 can slide along the sliding groove of the clamping block 3. When the guide rod 15 slides, it will synchronously drive the wedge-shaped block 14 to slide along the sliding groove of the clamping block 3, so that the position of the wedge-shaped block 14 can be adjusted. By adjusting the position of the wedge-shaped block 14, the clamping position of the clamping block 3 on the sample can be adjusted.

[0028] Conversely, the threaded rod 16 can be rotated in reverse, so that the threaded rod 16 drives the limiting block 17 to move in reverse. At this time, the limiting block 17 will be connected with the rack 18 in the sliding groove of the clamping block 3, and the limiting action of the rack 18 and the limiting block 17 on the guide rod 15 can be achieved. Thus, the position of the wedge-shaped block 14 can be fixed, thereby ensuring the stability of the entire limiting block 17.

[0029] As can be seen from Figures 1-4 in use, the threaded rod 16 can be rotated according to the size of the sample, so that the threaded rod 16 drives the limiting block 17 to separate from the rack 18 in the sliding groove of the clamping block 3 through a bearing. Without the limiting action of the limiting block 17 and the rack 18 on the guide rod 15, the wedge-shaped block 14 can slide along the sliding groove of the clamping block 3. By adjusting the position of the wedge-shaped block 14, the clamping position of the sample can be adjusted, so that different sizes of samples can be clamped.

[0030] In summary: the sampling clamp with the lifting structure can be installed on one side of the conveyor when in use. When the sample on the conveyor needs to be sampled, only the hydraulic cylinder 6 needs to be started to make the hydraulic cylinder 6 shrink. When the hydraulic rod shrinks, it will drive the connecting block 5 to move, so that the connecting block 5 drives the movable block 4 at the top to move. When the movable block 4 moves, it will drive the two sets of clamping blocks 3 to rotate through the sliding groove of the clamping block 3. When the clamping block 3 rotates, it can clamp the sample on the conveyor, thereby facilitating the clamping of the sample on the conveyor. This is the use feature of the sampling clamp with the lifting structure. The contents not described in detail in the description belong to the existing technology known to those skilled in the art.

[0031] Although the utility model has been explained in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
