[0033] like Figure 1-10 As shown, a reaction device for producing concrete admixtures comprises a cylinder 1 and a turntable 13 rotatably mounted on the top of the cylinder 1. A through slide 1301 is provided on the turntable 13 along its diameter direction, and sliders 12 are slidably mounted on both sides of the slide 1301. A rotating shaft 10 is provided at the slider 12. Figure 2 As described above, the top end of the rotating shaft 10 passes through the slider 12 upward and can rotate relative to the slider 12. Specifically, a bearing can be installed between the rotating shaft 10 and the slider 12.

[0034] Furthermore, combined with Figure 1-Figure 2 As shown, a box body 3 is fixedly arranged on the top surface of the turntable 13, and the bottom of the box body 3 is in an open state and communicated with the slide groove 1301, and a protrusion 15 is integrally formed at the top of the slider 12, and the protrusion 15 is in the box body 3, and a screw rod 16 is arranged in the box body 3 along its length direction, and the positions of the screw rod 16 near both ends are both bare rod structures, so that the screw rod 16 passes through the box body 3 and rotates with it, and one end of the screw rod 16 passing through the box body 3 is equipped with a bevel gear 14, and a bevel gear ring 17 meshing with the bevel gear 14 is arranged above the turntable 13, and the outer surface of the screw rod 16 is provided with two sections of external threads with opposite thread directions, and the screw rod 16 passes through the protrusion 15 and threads with the protrusion 15. Through this structure, the two protrusions 15 can be urged to approach or move away from each other during the rotation of the screw rod 16.

[0035] Refer again Figure 2As shown, in order to introduce different raw materials into the cylinder 1, a plurality of feed pipes are fixedly installed on the outer wall of the cylinder 1, and the feed pipes are connected to the cylinder 1. In actual use, the raw materials to be reacted are introduced into the cylinder 1 through the feed pipes, and the box body 3 is driven to rotate synchronously by driving the turntable 13 to rotate. In the process of the screw rod 16 driving the bevel gear 14 to rotate, the bevel gear 14 will mesh with the bevel gear ring 17, thereby driving the screw rod 16 to rotate. In the process of the screw rod 16 rotating, the protrusion 15 and the slider 12 can be prompted to move along the length direction of the box body 3, so as to adjust the position of the rotating shaft 10 in the cylinder 1. In the specific operation process, the rotating shaft 10 can be driven to rotate in the cylinder 1 by the turntable 13, which is beneficial to stirring the material in the cylinder 1, and by adjusting the position of the rotating shaft 10 in the cylinder 1, it is beneficial to expand the stirring range of the rotating shaft 10.

[0036] Reference Figure 1-Figure 2 As shown, a base 2 is fixedly installed at the bottom end of the cylinder 1, and the ends of the base 2 opposite to the cylinder 1 are both in an open state, so that the cylinder 1 and the base 2 are connected, and an annular recessed portion 201 is formed at the inner wall of the base 2, and a collecting assembly is provided at the bottom end of the two rotating shafts 10. In the initial state, the collecting assembly is attached to the bottom surface of the base 2, and during the stirring process of the rotating shaft 10, the collecting assembly can remain stable relative to the rotating shaft 10;

[0037] Furthermore, a spur gear 25 is installed at the top of the rotating shaft 10 through a clamping assembly, and a rack 23 meshing with the spur gear 25 is fixedly provided on the inner wall of the box body 3. When the rotating shaft 10 is clamped with the spur gear 25 through the clamping assembly, the spur gear 25 can only drive the rotating shaft 10 to rotate in a single direction. When the two rotating shafts 10 rotate so that the collecting assemblies on the two rotating shafts 10 are clamped, the two rotating shafts 10 can drive the collecting assemblies to move upward during the rotation process, so that the material in the cylinder 1 can be sampled and sent to the top position of the cylinder 1.

[0038] Reference Figure 2-Figure 3 , Figure 6-Figure 9 , Figure 11-13 As shown, the collecting assembly includes a collar 8 sleeved on the bottom end of the rotating shaft 10, the collar 8 can move along the axis direction of the rotating shaft 10 relative to the rotating shaft 10, a slide bar 9 is fixedly arranged on the outer surface of the collar 8, and a collecting box 7 is elastically mounted on the end of the slide bar 9 away from the collar 8;

[0039] Reference Fig.11As shown, a plug 30 is fixedly provided at one end of the slide bar 9 extending to the inside of the collection box 7, and a receiving chamber slidably matched with the plug 30 is provided on the collection box 7, so that the plug 30 and the receiving chamber are sealed, and a through hole 704 connected to the receiving chamber is provided on the bottom surface of the collection box 7, and a storage chamber 705 is provided on one side of the receiving chamber in the collection box 7. Specifically, a barrier portion is formed between the storage chamber 705 and the receiving chamber, and a penetrating feed port 703 is provided on the barrier portion, and the storage chamber 705 can be conducted with the receiving chamber through the provided feed port 703;

[0040] A slot 701 is provided on the end surface of one of the collection boxes 7 away from the rotating shaft 10, and the cross section of the slot 701 is T-shaped. An insert block 702 is fixedly provided on the end surface of the other collection box 7 away from the rotating shaft 10. Figure 3 As shown, a positioning block 19 is elastically mounted on the outer side of the insert block 702, and an inclined extrusion portion 20 is provided at one end of the positioning block 19 located on the outer side of the insert block 702. When the ends of the two collection boxes 7 are close to and fitted to each other, the insert block 702 on one of the collection boxes 7 can be inserted into the slot 701 of the other collection box 7, and the two collection boxes 7 can be locked by the cooperation of the positioning block 19 and the slot 701, thereby preventing the two collection boxes 7 from being separated.

[0041] In order to drive the ring 8 to move along the rotating shaft 10, a spiral limit groove 1001 is opened on the outer circumferential surface of the rotating shaft 10, and a limit block 801 that slides with the limit groove 1001 is fixedly provided on the inner wall of the ring 8. When the rotating shaft 10 rotates relative to the ring 8, the limit block 801 can drive the ring 8 to move upward relative to the rotating shaft 10 through the cooperation between the limit block 801 and the limit groove 1001.

[0042] Reference Figure 2 , Fig.10 As shown, the clamping assembly includes a first clamping block 26 and a second clamping block 28 elastically arranged on the outer peripheral wall of the rotating shaft 10 and close to the top position, the first clamping block 26 is provided with an inclined first inclined surface 2601 at one end away from the rotating shaft 10, and the second clamping block 28 is provided with an inclined second inclined surface 2801 at one end away from the rotating shaft 10. Two second electromagnets 27 are arranged on the rotating shaft 10, and the two second electromagnets 27 are respectively located at one end of the first clamping block 26 and the second clamping block 28 away from the spur gear 25. The first clamping block 26 and the second clamping block 28 are made of iron, and a plurality of clamping grooves 2501 matching with the first clamping block 26 and the second clamping block 28 are evenly opened on the inner wall of the spur gear 25. Fig.10As shown, the first inclined surface 2601 and the second inclined surface 2801 are set in opposite directions. Specifically, when only the first blocking block 26 is in the pop-up state, the spur gear 25 can only drive the rotating shaft 10 to rotate clockwise, and when only the second blocking block 28 is in the pop-up state, the spur gear 25 can only drive the rotating shaft 10 to rotate counterclockwise.

[0043] Reference Figure 2 , Figure 6 As shown, a foldable sealing belt 11 is fixedly arranged between the slider 12 and the end surface of the slide groove 1301 , and the front and rear side surfaces of the sealing belt 11 are in contact with the side walls of the slide groove 1301 , and a sampling port 31 is formed between the two sliders 12 .

[0044] In the initial state, the two collecting boxes 7 are in a state of being separated from each other, and the two collecting boxes 7 are in the same straight line. When it is necessary to sample the material in the cylinder 1, the second electromagnet 27 at the first clamping block 26 can be in a power-off state, so that the first clamping block 26 can be ejected and inserted into the clamping slot 2501, so that the spur gear 25 can drive the rotating shaft 10 to rotate clockwise through the cooperation between the first clamping block 26 and the clamping slot 2501. In this process, the two collecting boxes 7 will also rotate synchronously with the rotating shaft 10. At the same time, through the threaded connection between the screw rod 16 and the protrusion 15 The two rotating shafts 10 are connected so that during the rotation of the turntable 13, the two rotating shafts 10 can gradually approach each other. Therefore, during the rotation of the two collecting boxes 7 by 180 degrees, the ends of the two collecting boxes 7 away from the rotating shafts 10 will gradually approach each other and finally fit completely together, so that the insert block 702 on one collecting box 7 can be inserted into the slot 701 of the other collecting box 7, and the two collecting boxes 7 can be locked by the cooperation of the positioning block 19 and the slot 701, thereby preventing the two collecting boxes 7 from separating. When the turntable 13 continues to rotate, the rotating shaft 10 can be continuously driven to rotate by the spur gear 25, but due to The two collecting boxes 7 are mutually engaged, so that the collecting boxes 7 cannot rotate synchronously with the rotating shaft 10. Therefore, when the rotating shaft 10 is continued to be driven to rotate by the spur gear 25, the cooperation between the limit block 801 and the limit groove 1001 can drive the collar 8 and the collecting box 7 outside the collar 8 to move upward along the rotating shaft 10. Since the first clamping block 26 cooperates with the clamping groove 2501, the gear can only drive the rotating shaft 10 to rotate clockwise. Therefore, when the rotating disk 13 rotates in the opposite direction, the spur gear 25 cannot drive the rotating shaft 10 to rotate in the opposite direction. Through this structure, the rotating disk 13 can rotate in the opposite direction. The collection box 7 can only be moved upwards during the process of rotating in a single direction. When the two collection boxes 7 connected to each other rise to the bottom surface of the turntable 13, the two collection boxes 7 can be inserted into the sampling port 31 (i.e., between the two sliders 12). When the two sliders 12 are attached to the end surfaces of the collection box 7, the turntable 13 can stop rotating. At this time, the staff can take out the materials collected in the collection box 7, and the chute 1301 can be sealed by the cooperation of the sealing belt 11, the slider 12 and the collection box 7, so as to avoid the gas in the cylinder 1 from overflowing during the material taking process.

[0045] In addition, during the upward movement of the two collecting boxes 7, the two rotating shafts 10 are in a reciprocating state. When the two rotating shafts 10 move away from each other, the rotating shafts 10 can pull the plug 30 through the sliding rod 9. Fig.11As shown, when the plug 30 moves outward relative to the collecting box 7, the external raw materials can be sucked into the accommodating chamber through the through hole 704, and when the two rotating shafts 10 are close to each other, the plug 30 can move inward relative to the collecting box 7, so as to press the raw materials in the accommodating chamber into the storage chamber 705, so that the staff can take it out. Of course, a one-way valve can be installed at the through hole 704 and the feed port 703, so that the raw materials in the barrel 1 can only enter the accommodating chamber in one direction, and the raw materials in the accommodating chamber can also only enter the storage chamber 705 in one direction. Since the suction and thrust generated when the plug 30 moves are relatively large, some relatively viscous raw materials can also be stably sampled through this structure;

[0046] During the ascending process, the collecting box 7 is in a state of continuous material absorption due to the reciprocating movement of the two rotating shafts 10 , so that each layer of raw materials in the cylinder 1 can be extracted.

[0047] In summary, this device can stir the material in the cylinder 1 by means of the rotating shaft 10, and by means of a collecting box 7 at the bottom end of the rotating shaft 10, when the two collecting boxes 7 are engaged with each other and the rotating shaft 10 rotates, the collecting box 7 can move upward along the rotating shaft 10, thereby sending the extracted raw materials to the turntable 13, and the collecting boxes 7 engaged with each other can be located at the sampling port 31, thereby preventing the gas in the cylinder 1 from overflowing during the material collection process of the staff.

[0048] like Figure 1-Figure 10 As shown, a first electromagnet 21 cooperating with the positioning block 19 is arranged at one end of the insert block 702, and the positioning block 19 is made of iron. In actual use, when the staff completes the material taking, the second electromagnet 27 at the first clamping block 26 can be energized to shrink the first clamping block 26 into the rotating shaft 10, and the second electromagnet 27 at the second clamping block 28 can be de-energized to make the second clamping block 28 in a pop-up state. In this process, the spur gear 25 can only drive the rotating shaft 10 to rotate counterclockwise, thereby The cooperation between the limit block 801 and the limit groove 1001 can drive the collection box 7 to move downward until it is in contact with the bottom surface of the base 2. At this time, the first electromagnet 21 can be energized, so that the positioning block 19 can be disengaged from the slot 701, allowing the two collection boxes 7 to be separated. When the rotating shaft 10 drives the collection box 7 to rotate 180° to reset, the second electromagnets 27 at the first block 26 and the second block 28 can be energized. At this point, the collection box 7 can be reset, making it easier to use it next time.

[0049] like Figure 1As shown, a connecting ring 5 is fixedly provided on the top surface of the turntable 13, and a motor is fixedly installed on the outer side of the cylinder 1. The output shaft of the motor and the outer side of the connecting ring 5 are fixedly sleeved with pulleys, and the outer sides of the two pulleys are sleeved with belts 6. Through this structure, when the motor rotates forward or reversely, it can drive the turntable 13 to rotate forward or reversely.

[0050] A U-shaped bracket 4 is fixedly arranged between the top surface of the bevel gear ring 17 and the top end surface of the cylinder 1. This structure facilitates the installation of the bevel gear ring 17 so that the turntable 13 can rotate relative to the bevel gear ring 17.

[0051] A through discharge port 202 is provided at the bottom of the base 2 , and a liquid discharge pipe is fixedly provided on the bottom surface of the base 2 at the discharge port 202 .

[0052] A plurality of supporting legs are fixedly disposed at the bottom of the base 2 .

[0053] Reference Figure 2 As shown, by providing a recessed portion 201 on the inner wall of the base 2, interference between the collecting box 7 and the inner wall of the base 2 during the stirring process can be avoided.

[0054] The top and bottom of the turntable 13 are both provided with support rings 18 . The support rings 18 are fixedly mounted on the inner wall of the cylinder 1 , and the turntable 13 can rotate relative to the support rings 18 .

[0055] The top surfaces of the box body 3 and the collecting box 7 are both provided with openings 32, and the openings 32 are sealed by covers. When the staff needs to take materials, they only need to open the covers on the collecting box 7 and the top of the box body 3.

[0056] The top surface of the collecting box 7 is higher than the top surface of the sliding rod 9 , so as to facilitate the delivery of the two collecting boxes 7 connected to each other to the sampling port 31 .

[0057] Reference Figure 3 As shown, a mounting groove with a cross-shaped cross-section is provided on the outer peripheral wall of the insert block 702, and the positioning block 19 is overall configured in a T shape. A supporting spring is provided between the bottom surface of the positioning block 19 and the inner end surface of the mounting groove, and the first electromagnet 21 is fixedly provided on the inner bottom surface of the mounting groove. Through this structure, elastic cooperation between the positioning block 19 and the insert block 702 can be achieved.

[0058] like Figure 4As shown, a bearing is installed between the screw rod 16 and the bevel gear 14. In actual use, a circular hole can be opened on the outer peripheral wall of the screw rod 16 and near the end. A protrusion 22 is slidably arranged in the circular hole, and the end of the protrusion 22 close to the bevel gear 14 is an arc surface structure. A first spring is fixedly arranged between the protrusion 22 and the inner end surface of the circular hole. A socket matching the protrusion 22 is opened on the inner wall of the bevel gear 14. In the initial state, the arc surface structure at one end of the protrusion 22 is in the socket. When the two collecting boxes 7 are plugged in, the distance moved by the rotating shaft 10 relative to the turntable 13 is limited. Through this structure, when the rotating shaft 10 moves to the extreme position and cannot move, the pressure between the protrusion 22 and the socket increases, so that one end of the protrusion 22 can be moved out of the socket, thereby avoiding interference between the screw rod 16 and the bevel gear 14.

[0059] Reference Figure 7 As shown, the protrusion 15 is provided with a circular groove for mounting the spur gear 25 , and the diameter of the circular groove is greater than the side length of the protrusion 15 (the protrusion 15 may be a cubic structure), so that the spur gear 25 can mesh with the rack 23 through the circular groove.

[0060] Reference Figure 8-Figure 9 As shown, a plurality of stoppers 29 are elastically installed on the outer wall of the rotating shaft 10 and near the bottom end. The stoppers 29 are located above the collar 8. The stoppers 29 can limit the position of the collar 8 in the vertical direction, thereby preventing the collar 8 and the collecting box 7 from moving relative to the rotating shaft 10 during the stirring process. A strip groove that slidably cooperates with the stoppers 29 is provided on the outer wall of the rotating shaft 10, and a second spring is fixedly provided between the inner end surface of the strip groove and the stoppers 29. An inclined guide surface 2901 is provided at one end of the stopper 29 away from the rotating shaft 10, and the guide surface 2901 is located at the top and bottom surfaces of the stopper 29. Through this structure, when the two collecting boxes 7 are connected, the cooperation between the limit block 801 and the limit groove 1001 makes the ring 8 tend to move relative to the rotating shaft 10, thereby increasing the pressure between the ring 8 and the stopper 29, so that the stopper 29 can be compressed into the rotating shaft 10, and the ring 8 continues to move through the stopper 29.

[0061] Reference Fig.10 As shown, the rotating shaft 10 is provided with a rectangular groove which slides with the first clamping block 26 and the second clamping block 28, and the second electromagnet 27 is fixedly installed at the inner end surface of the rectangular groove. Springs are fixedly arranged between the first clamping block 26 and the second electromagnet 27 and between the second clamping block 28 and the second electromagnet 27.

[0062] Reference Fig.11 As shown, a limit spring is fixedly arranged between the plug 30 and the inner end surface of the accommodating chamber, and the limit spring is sleeved on the outside of the slide rod 9. The slide rod 9 passes through the collection box 7 and slides with it.

[0063] like Fig.12 As shown, the slider 12 is provided with a through hole matching the rotating shaft 10, and a mounting hole is provided on the inner wall of the through hole, and a pressure block 24 is slidably arranged in the mounting hole, and the end of the pressure block 24 close to the rotating shaft 10 is an arc surface, and a third spring is fixedly arranged between the pressure block 24 and the inner end surface of the mounting hole, and a positioning hole matching the pressure block 24 is provided on the outer wall of the rotating shaft 10. In the initial state, one end of the pressure block 24 is in the positioning hole, and a part of the arc surface on the pressure block 24 is located outside the positioning hole. This structure is conducive to ensuring that the rotating shaft 10 and the slider 12 remain relatively stable during the stirring process. When the rotating shaft 10 is driven to rotate by the spur gear 25, the pressure between the pressure block 24 and the side wall of the positioning hole increases, so that the pressure block 24 can be compressed into the mounting hole.
