Description

Technical Field

[0001] The present invention relates to the technical field of mixers, and in particular to a mixer for mortar preparation. Background Art

[0002] Mortar is an adhesive substance used for bricklaying in construction, which is synthesized by adding water to a certain proportion of sand and cementing materials (such as cement, lime paste, clay, etc.), and is also called mortar. During the preparation of mortar, the above-mentioned materials need to be stirred. For example, a Chinese patent with the authorization announcement number CN113664994B discloses a mixer for mortar preparation, including a support member and a housing, and further including: a driving mechanism fixedly connected to the support member, and the driving mechanism is used to drive the housing to rotate reciprocally.

[0003] Although the technical solution in the above document can efficiently prepare mortar, the equipment has a large size, a large one-time preparation amount of mortar, is inconvenient to carry, and is difficult to meet the use requirements of home improvement construction sites. In the existing technology for mortar preparation in home improvement construction sites, either manual stirring with a shovel is used, or the materials are put into a container and then a handheld power tool is used to stir the materials in the container. The former not only requires a certain amount of site space, but also causes the problem of mortar residue at the site after mortar preparation, and the manual burden is large during the preparation process. The latter, although avoiding the need for a site, in the actual operation process, since the materials are first poured into the container and the water is added gradually, inevitably, when the handheld power tool stirs the materials, the materials will fly, affecting the health of the staff, and there will be sedimentation of materials at the bottom of the container, which is likely to cause waste of resources. The power tool will generate relatively large noise and vibration to the building when stirring the materials in the container. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. By arranging a frame on the trolley body, and then arranging the mixing component and the material storage mechanism on the frame, a small mortar mixing device is formed, which can be conveniently applied to the mortar preparation on the home decoration construction site, replacing the existing mortar preparation technology on the home decoration construction site, reducing the burden on the staff, protecting the construction site environment, avoiding waste of resources, reducing noise pollution, and reducing the vibration effect on the building.

[0016] 2. The stock storage mechanism is located above the mixing component. Materials can be poured into the stock storage mechanism in advance according to the preparation requirements of the mortar. Then, when the driving mechanism in the mixing component runs forward and drives the mixing mechanism to move backward, the reciprocating movement of the feeding mechanism is driven, so as to realize the intermittent feeding of various materials in the stock storage mechanism. During the intermittent feeding of various materials, due to the operation of the mixing mechanism, the preliminary mixing of various materials is realized, the mixing time during the subsequent preparation of the mortar with water is shortened, and the preparation efficiency of the mortar is improved.

[0017] 3. During the process of the materials being intermittently fed from the stock storage mechanism into the mixing component, they are in a closed environment, thus avoiding the scattering of the materials in the air, ensuring the construction environment at the construction site, and protecting the physical health of the staff.

[0018] 4. When the driving mechanism in the mixing component runs backward, it not only drives the mixing mechanism to rotate forward, but also synchronously realizes the movement of the swinging component. At this time, the forward operation of the mixing mechanism does not drive the operation of the feeding mechanism, and various materials required for the subsequent preparation of the mortar can be poured into the stock storage mechanism, further shortening the subsequent preparation time of the mortar. The movement of the swinging component will cause the mixing component to move integrally back and forth on the frame, further improving the preparation effect of the mortar.

[0019] 5. When the mixing component makes an integral back-and-forth movement, the auxiliary mechanism located on the mixing mechanism realizes the lifting adjustment of the mixing mechanism in cooperation with the frame, thus not only further improving the mixing efficiency of the materials in the mixing barrel, but also the mixing mechanism makes a lifting movement while rotating, realizing the mixing of the materials at different height positions in the mixing barrel, making the materials have a certain up-and-down turning effect, and being able to turn the materials at the bottom of the mixing barrel while improving the mixing efficiency of the materials.

[0020] 6. The mixing component in the mixing mechanism can be combined with the sealing mechanism when the mixing mechanism makes a lifting movement. Then, the mixing rod in the mixing component makes a synchronous angle adjustment along with the lifting movement of the mixing mechanism, further improving the mixing effect of the materials. Combining with the lifting movement of the mixing mechanism, the deposition of materials inside the mixing barrel is avoided to the greatest extent, and the waste of resources is reduced.

[0021] 7. The mixing component is designed to be suspended on the frame, and the guiding mechanism ensures the stability of the back-and-forth movement of the mixing barrel, reducing the contact with the ground. Thus, during the operation of the equipment, the noise pollution is reduced, the vibration effect on the building is alleviated, the influence on other residents in the community is reduced, and the construction progress is ensured.

The configuration of the positioning holes and the positioning rods ensures the stable lifting movement of the joint plate 391 under the cooperation of the dynamic wedges 392 and the static wedges 393.

[0046] The driving mechanism 310 includes a double-shaft motor 3101 fixedly connected to the substrate 36 through bolts. Transmission shafts are installed at both output ends of the double-shaft motor 3101. The bottom end of the lower transmission shaft extends into the interior of the housing 371, and a gear column 3102 is installed. The gear column 3102 is in meshing transmission with the driven gear 384. The gear column 3102 provides driving force for the movement of the stirring mechanism 38, and the setting of the gear column 3102 ensures that the driven gear 384 can still be in meshing transmission with it during the lifting movement.

[0047] The top end of the upper transmission shaft extends above the top cover 33, and a swing assembly 3103 is installed. The swing assembly 3103 includes an end plate 31031 fixedly connected to the top end of the upper transmission shaft by bolts. A plurality of second spring telescopic rods 31032 are arranged on the peripheral wall of the end plate 31031 in the circumferential direction, and the output ends of the second spring telescopic rods 31032 are in rolling connection with spherical balls. The number of the second spring telescopic rods 31032 ranges from three to ten, and ten are adopted in this embodiment.

[0048] The four sides of the end plate 31031 are rotationally connected with a cam 31033 on the top shell wall of the top cover 33. A traction rod 31034 is sleeved on the top of the cam 31033 through a convex rod. One end of the traction rod 31034 away from the cam 31033 is movably connected to the fixed column 23.

[0049] A plurality of receiving grooves are arranged on the inner circumferential shell wall of the cam 31033 in the circumferential direction, and the inner wall of the receiving groove is in rolling contact with the spherical ball. The number of the receiving grooves ranges from three to ten, and ten are adopted in this embodiment, which is consistent with the number of the second spring telescopic rods 31032. Thus, when the end plate 31031 moves, the cam 31033 can be stably driven by the second spring telescopic rods 31032. The receiving grooves are arranged in the clockwise direction, so that the cam 31033 will not be driven to move when the end plate 31031 moves clockwise.

[0050] The feeding mechanism 311 includes box bodies 3111 symmetrically arranged on the left and right on the substrate 36. An outlet pipe is installed at the bottom of each box body 3111, and the bottom end of the outlet pipe penetrates through the substrate 36.

[0051] A feeding pipe is arranged on the top shell wall of each box body 3111, and the top end of the feeding pipe penetrates through the top cover 33 and is respectively connected to the corresponding connecting pipe. The materials in the storage mechanism 4 enter into the respective feeding pipes under the action of the connecting pipes, and then can be discharged through the corresponding outlet pipes.

[0052] A round rod 3112 is arranged between the two box bodies 3111, and a support seat and a return spring are sleeved on the round rod 3112. Among them, there are two return springs, which are respectively located on both sides of the support seat. A sealing plate 3113 is installed on the top of the support seat, and both sides of the sealing plate 3113 extend into the corresponding box bodies 3111 respectively for blocking the feeding pipes. Two passing holes are opened on the sealing plate 3113, corresponding to the respective feeding pipes respectively, for the feeding passage of the materials. When the sealing plate 3113 moves left and right, the respective passing holes on it move synchronously, so as to realize the intermittent feeding of the materials in each box body 3111.

[0053] A frame 3114 is installed at the rear side of the blocking plate 3113 by bolts, and the frame 3114 is sleeved on the follower 312. A knocking member 3115 for knocking the feed pipe is installed at the top of the blocking plate 3113. When the follower 312 moves, it contacts the frame 3114, causing the blocking plate 3113 to perform reciprocating motion in the left-right direction. During the movement of the blocking plate 3113, the knocking member 3115 is synchronously driven to move, realizing the vibration of the feed pipe on the corresponding box body 3111, thereby ensuring the smooth feeding of materials.

[0054] Please refer to Figure 5 and Figure 12 In the embodiment of the present invention, the water spraying mechanism 5 includes a hollow ring provided on the bottom shell wall of the carrier ring 35. A plurality of nozzles are provided on the bottom of the hollow ring along the circumferential direction. A water inlet pipe is installed on the peripheral wall of the hollow ring. The right end of the water inlet pipe penetrates the peripheral wall of the stirring barrel 31 and is installed with a conduit through a connector. A control valve is provided on the conduit. The adjustment of the control valve allows external water resources to enter the water inlet pipe, then enter the hollow ring, and be dispersed and sprayed out from each nozzle, realizing the perfusion of water resources inside the stirring barrel 31.

[0055] The working principle of the present invention is as follows: When mortar preparation is required, first adjust the lifting cushion member 12 on the trolley main body 1 so that the product can be stably parked. Then open each cabinet door 44 in the storage mechanism 4, and quantitatively pour various materials required for mortar preparation into the box body 41 respectively. The various materials are located on both sides of the partition plate 42, and finally close the cabinet door 44.

[0056] Start the forward rotation of the double-shaft motor 3101 of the drive mechanism 310 in the stirring component 3 through an external controller main body. When the double-shaft motor 3101 moves, it drives the corresponding transmission shaft to move, causing the gear column 3102 and the end plate 31031 in the swing assembly 3103 to rotate synchronously in the positive direction.

[0057] When the end plate 31031 rotates in the positive direction, a plurality of second spring telescopic rods 31032 thereon move synchronously. Since the ball on the output end of the second spring telescopic rod 31032 is in rolling contact with the inner wall of the receiving groove on the inner ring of the cam 31033. At this time, when the cam 31033 is connected and fixed to the fixed column 23 by the traction rod 31034, the cam 31033 has a relatively high resistance, and thus the end plate 31031 drives a plurality of second spring telescopic rods 31032 to rotate self in the cam 31033.

[0058] The gear column 3102 meshes with the driven gear 384 in the stirring mechanism 38 for transmission. Thus, when the gear column 3102 rotates forward, the shaft rod 381 in the stirring mechanism 38 moves in the reverse direction. When the shaft rod 381 rotates in the reverse direction, it drives the stirring blade group 382, the stirring assembly 383, and the transmission part 385 arranged thereon to rotate synchronously. Among them, the ring 3851 in the transmission part 385 drives the spring telescopic rod 3852 to move along with the shaft rod 381. Since the inner ring of the auxiliary ring 3121 is provided with a special-shaped groove, when the ring 3851 drives the spring telescopic rod 3852 to move in the reverse direction, the spring telescopic rod 3852, under the cooperation of the special-shaped groove, synchronously rotates the auxiliary ring 3121 in the driven part 312. The movement of the auxiliary ring 3121 makes the special-shaped sleeve 3122 move synchronously. When the special-shaped sleeve 3122 rotates, it knocks and pushes the frame 3114 in the feeding mechanism 311, causing it to perform a lateral reciprocating movement.

[0059] During the reciprocating movement of the frame 3114, it drives the blocking plate 3113 to perform a reciprocating movement in the two boxes 3111. As the blocking plate 3113 moves in the box 3111, the various through holes on the blocking plate 3113 intermittently coincide with the feeding pipes in the corresponding boxes 3111. Under the action of gravity, various materials in the storage mechanism 4 enter the corresponding feeding pipes respectively under the guiding action of the corresponding connecting pipes, then enter the corresponding discharge pipes through the through holes, and are put into the interior of the mixing barrel 31 by the discharge pipes. During the reciprocating movement of the blocking plate 3113, it synchronously drives the knocking parts 3115 assembled thereon to move. Thus, during the movement of the knocking parts 3115, they will knock and vibrate the feeding pipes on each box 3111, thereby further ensuring the smoothness of the material feeding.

[0060] During the intermittent feeding of the materials, the stirring mechanism 38 continuously moves, thereby pre-stirring and mixing the falling materials.

[0061] When the feeding of the materials is completed, the double-shaft motor 3101 in the driving mechanism 310 is controlled by an external controller main body. When the stirring mechanism 38 returns to its initial position, the double-shaft motor 3101 stops running. At this time, the feeding mechanism 311 also returns to its initial position, and the various through holes on the blocking plate 3113 in the feeding mechanism 311 are respectively misaligned with the discharge pipes in the two boxes 3111, achieving the blocking effect on them.

[0062] Then, the double-shaft motor 3101 in the driving mechanism 310 is started to reverse again through the external controller main body, and the control valve is operated to intermittently spray water resources into the interior of the mixing barrel 31 through the water spraying mechanism 5. During the reverse rotation of the double-shaft motor 3101, the gear column 3102 and the end plate 31031 in the swinging assembly 3103 rotate synchronously in the reverse direction.

[0063] At this time, when the end plate 31031 drives the second spring telescopic rods 31032 thereon to reverse, each of the second spring telescopic rods 31032 drives the cam 31033 to rotate during the contact with the receiving groove on the inner ring of the cam 31033. When the cam 31033 rotates, since the other end of the traction rod 31034 is movably connected to the fixed column 23, and then with the frame 2 fixed, the stirring member 3 undergoes an overall forward and backward displacement, realizing the shaking of the stirring barrel 31, and further improving the mixing effect of the materials inside it.

[0064] The gear column 3102 drives the shaft rod 381 in the stirring mechanism 38 to rotate forward through meshing transmission with the driven gear 384. When the shaft rod 381 rotates forward, it drives the transmission member 385 to rotate forward synchronously. When the transmission member 385 rotates forward, since the blocking plate 3113 in the feeding mechanism 311 is in the centered state under the action of the return spring, the frame 3114 has a greater resistance to the driven member 312, making it difficult for the driven member 312 to deflect significantly when the first spring telescopic rod 3852 rotates forward. Therefore, the movement of the transmission member 385 at this time cannot drive the driven member 312 to adjust the feeding mechanism 311.

[0065] During the forward rotation of the shaft rod 381, it will also drive the stirring blade group 382 and the stirring assembly 383 thereon to move synchronously. When the stirring blade group 382 and the stirring assembly 383 rotate with the shaft rod 381, the materials in the stirring barrel 31 are stirred and mixed. When the stirring barrel 31 moves forward and backward, the joint plate 391 of the auxiliary mechanism 39 on the shaft rod 381 drives each moving wedge block 392 to move forward and backward. During the movement of the moving wedge block 392, it cooperates with the corresponding fixed wedge block 393, thereby realizing the lifting movement of the shaft rod 381 in the stirring mechanism 38 during the rotational movement.

[0066] The rotational lifting of the shaft rod 381 enables the stirring blade group 382 and the stirring assembly 383 to move synchronously, thereby efficiently and evenly stirring and mixing the materials in the stirring barrel 31. Moreover, during the lifting process of the shaft rod 381, since the height of the connecting rod 3833 in the stirring assembly 383 is fixed, when the shaft rod 381 lifts, each connecting rod 3833 respectively pushes against the corresponding stirring rod 3832, causing it to adjust the angle with the lifting movement of the shaft rod 381, further improving the mixing and processing efficiency of the materials.

[0067] During the mixing of the materials in the stirring barrel 31, the cabinet door 44 in the storage mechanism 4 can be opened, and then the materials required for the subsequent mortar preparation can be quantitatively stored in the box body 41. Finally, the cabinet door 44 is closed again to prevent the materials on the inner wall of the box body 41 from scattering to the outside.

[0068] After the mixing of the materials is completed, the driving mechanism 310 is turned off through an external controller main body, and the bucket for carrying the mortar is placed below the discharge port of the mixing bucket 31. Then, the opening and closing of the bottom cover 32 are adjusted to facilitate the mortar in the mixing bucket 31 to fall into the lower bucket.

[0069] When the equipment is not needed, the bottom cover 32 can be closed first, and then water resources are intermittently sprayed into the interior of the mixing bucket 31 through the water spraying mechanism 5 by an external controller main body. Then, the double-shaft motor 3101 in the driving mechanism 310 is reversed to quickly clean the mortar attached to the inner wall of the mixing bucket 31 and the mixing mechanism 38. Finally, the bottom cover 32 can be opened to discharge sewage and waste under the condition of turning off the driving mechanism 310 and stopping the water supply.

[0070] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
