Description

Technical Field

[0001] The present invention relates to the technical field of construction machinery, and particularly relates to a mixer for building construction. Background Art

[0002] House construction is the process of building a house. Mortar is essential in the process of house construction. The raw materials of mortar are solids, and water and other materials need to be added to them for mixing to reach a paste state. After the mortar dries, it becomes very hard and thus plays a fixing role. Due to the action of gravity on the raw materials during the mixing of traditional mixers, there are problems that the raw materials are prone to sediment at the bottom and the mixing is uneven. And the uneven mixing of the raw materials will directly affect the hardness of the subsequent mortar, and the insufficient hardness of the mortar will affect the stability of the masonry.

[0003] In view of the problems existing in the above-mentioned prior art, we have designed a mixer for building construction that can uniformly mix mortar in all directions on the whole and at the bottom. Summary of the Invention

[0004] In order to overcome the disadvantages that the raw materials are affected by gravity during the mixing of traditional mixers, prone to sediment at the bottom, and the mixing is uneven, the technical problem of the present invention is: to provide a mixer for building construction that can uniformly mix mortar in all directions on the whole and at the bottom.

[0005] The technical solution of the present invention is: a mixer for building construction, including a support frame, a placement frame, a discharge valve, a chassis, a first frame, a second frame, a limiting rod, a fixing plate, a first motor, a stirring shaft, a bottom stirring mechanism, and a middle stirring mechanism. The upper side of the support frame is connected with a placement frame. The lower part inside the placement frame is rotatably connected with a chassis. A material discharge port is opened inside the chassis. The lower side of the placement frame is fixedly connected with a discharge valve. When the chassis rotates to connect the material discharge port with the discharge valve, the valve is opened so that the mixed mortar flows out from the discharge valve. A groove is opened on the chassis. Both the front and rear sides inside the placement frame are connected with fixing plates. The fixing plates are all slidably connected with limiting rods. A first frame is welded between the limiting rods. The first frame is located in the groove of the chassis. A groove is opened on the first frame. The second frame is connected in the groove of the first frame. Thus, when cleaning is required, the first frame and the second frame can be disassembled to increase the service life of the equipment. The upper part of the front side of the placement frame is fixedly connected with a support rod. The upper side of the support rod is connected with a first motor. Three stirring shafts are uniformly fixedly connected to the output shaft of the first motor. A bottom stirring mechanism for stirring the mortar accumulated at the bottom is connected to the placement frame. The bottom stirring mechanism is connected with the chassis. The middle parts of the stirring shafts are all connected with a middle stirring mechanism for stirring the mortar in the middle.

[0006] Optionally, the bottom stirring mechanism includes a second motor, a first gear, a second gear, and a stirring shaft. A second motor is connected to the rear side of the placement frame. A first gear is connected to the output shaft of the second motor. A second gear is connected to the outer side of the chassis. The first gear meshes with the second gear. Three stirring shafts are evenly and fixedly connected to the upper side of the chassis. The stirring shafts are in contact with the output shaft of the first motor.

[0007] Optionally, the middle stirring mechanism includes a connecting rod, a swinging rod, a limiting frame, and a slide rail. Slide rails are slidably connected to the inner sides of the stirring shafts. Limiting frames are fixedly connected to the left sides of the slide rails. The limiting frames are slidably connected to the swinging rods. Connecting rods are rotatably connected to the lower sides of the swinging rods.

[0008] Optionally, it further includes an anti-sticking mechanism for preventing mortar from sticking to the inner wall of the mixer. The anti-sticking mechanism includes a first ball rod and a second ball rod. The first ball rod is fixedly connected to the upper side of the outer part of the chassis. The second ball rod is fixedly connected to the outer part of the right side of the first frame. The upper side of the first ball rod and the lower side of the second ball rod are both semi-cylinders. The rotation of the second gear drives the rotation of the chassis. Thus, the first ball rod on the chassis rotates accordingly. When the first ball rod contacts the second ball rod, the first ball rod squeezes the second ball rod upward, driving the first frame and the second frame to move upward. When the first ball rod passes over the second ball rod, the second ball rod, the first frame, and the second frame reset downward due to the action of gravity. Rotating repeatedly like this makes the whole of the first frame and the second frame shake, preventing the mortar from sticking.

[0009] Optionally, it further includes an adjusting mechanism for stirring the mortar at the position where it is not evenly stirred. The adjusting mechanism includes a nut and a pushing plate. Through grooves are opened on the upper sides of the stirring shafts. Nuts are slidably connected to the inner sides of the through grooves. Pushing plates are threadedly connected to the upper sides of the nuts.

[0010] Optionally, it further includes a scraping mechanism for scraping the mortar on the inner wall of the mixer. The scraping mechanism includes a scraping frame and a scraping iron ring. Three scraping frames are evenly and fixedly connected to the inner side of the placement frame. A scraping iron ring is fixedly connected to the lower ends of the three scraping frames. The outer side of the scraping iron ring fits with the second frame.

[0011] Optionally, it further includes a limiting mechanism for fixing the position of the feeding port. The limiting mechanism includes a clamping shaft, a first fixing block, a second fixing block, and a clamping plate. The first fixing block and the second fixing block are fixedly connected to the right side of the placement frame. The second fixing block is located below the first fixing block. The clamping plate is slidably connected to the right side of the second fixing block. The clamping shaft is slidably connected between the first fixing block and the clamping plate. A clamping groove is opened on the outer side of the chassis.

[0012] The beneficial effects are as follows: 1. In the present invention, through the rotation of the stirring shafts, the connecting rods, and the swinging rods, and the rotation of the stirring shafts on the upper side of the chassis, the mortar can be evenly stirred in multiple aspects, including the whole, the middle, and the bottom.

[0013] 2. Through the contact of the first rod and the second rod, the overall shaking can be driven to prevent the mortar from sticking to the inner wall of the mixer;

[0014] 3. By moving the positions of the push plate and the nut, the position to be stirred can be stirred more evenly;

[0015] 4. Through the overall shaking of the first frame and the second frame, the mortar inside the first frame and the second frame can be scraped off with the scraping iron ring;

[0016] 5. Through the rotation of the chassis, the card slot on the outer side of the chassis is aligned with the groove on the outer side of the placement frame, so that the feeding port is communicated with the discharge valve. Inserting the clamping plate into the card slot can prevent the position of the feeding port from shifting, and then the valve can be opened to take out the stirred mortar.

Specific embodiments

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment 1

[0033] A mixer for construction engineering construction, as Figures 1-7As shown in the figure, it includes a support frame 1, a placement frame 2, a discharge valve 21, a chassis 3, a first frame 4, a second frame 41, a limiting rod 42, a fixing plate 43, a first motor 5, a stirring shaft 6, a bottom stirring mechanism 7 and a middle stirring mechanism 8. The upper side of the support frame 1 is connected with the placement frame 2. The lower part inside the placement frame 2 is rotatably connected with the chassis 3. A material discharge port 22 is opened inside the chassis 3. The lower side of the placement frame 2 is fixedly connected with the discharge valve 21. When the chassis 3 rotates to make the material discharge port 22 communicate with the discharge valve 21, the valve is opened so that the stirred mortar flows out from the discharge valve 21. A groove is opened on the chassis 3. Both the front and rear sides inside the placement frame 2 are connected with the fixing plate 43. The limiting rods 42 are slidably connected to the fixing plates 43. The first frame 4 is welded between the limiting rods 42. The first frame 4 is located in the groove of the chassis 3. A groove is opened on the first frame 4. The second frame 41 is connected in the groove of the first frame 4. Thus, when cleaning is needed, the first frame 4 and the second frame 41 can be disassembled to increase the service life of the equipment. The upper part of the front side of the placement frame 2 is fixedly connected with a support rod. The upper side of the support rod is connected with the first motor 5. Three stirring shafts 6 are evenly fixedly connected to the output shaft of the first motor 5. The middle part of each stirring shaft 6 is connected with a middle stirring mechanism 8 for stirring the middle mortar. A bottom stirring mechanism 7 for stirring the bottom accumulated mortar is connected to the placement frame 2. The bottom stirring mechanism 7 is connected with the chassis 3.

[0034] The bottom stirring mechanism 7 includes a second motor 71, a first gear 72, a second gear 73 and a stirring shaft 74. The second gear 73 is connected to the outside of the chassis 3. The second motor 71 is connected to the rear side of the placement frame 2. The first gear 72 is connected to the output shaft of the second motor 71. The first gear 72 meshes with the second gear 73. Three stirring shafts 74 are evenly fixedly connected to the upper side of the chassis 3. The stirring shafts 74 are in contact with the output shaft of the first motor 5.

[0035] The middle stirring mechanism 8 includes a connecting rod 81, a swinging rod 82, a limiting frame 83 and a slide rail 84. Slide rails 84 are slidably connected to the inner sides of the stirring shafts 6. The limiting frames 83 are fixedly connected to the left sides of the slide rails 84. The swinging rods 82 are slidably connected to the limiting frames 83. The connecting rods 81 are rotatably connected to the lower sides of the swinging rods 82. The rotation of the stirring shafts 6 drives the swinging rods 82 and the connecting rods 81 to rotate.

[0036] When people need to stir mortar, pour the mortar into the first frame 4 and the second frame 41 from above the mixer. Start the first motor 5. The output shaft of the first motor 5 rotates to drive the stirring shaft 6 to rotate. The stirring shaft 6 rotates to drive the connecting rod 81 and the swing rod 82 to rotate, so that the stirring shaft 6, the connecting rod 81 and the swing rod 82 rotate in the same direction together. In this way, the mortar in the whole and the middle can be stirred. Start the second motor 71. The second motor 71 drives the first gear 72 to rotate. The first gear 72 meshes with the second gear 73, so that the second gear 73 rotates, thereby driving the chassis 3 and the stirring shaft 74 fixedly connected to the upper side of the chassis 3 to rotate. In this way, the mortar at the bottom can be stirred. Rotate repeatedly to make the mortar evenly stirred. After the stirring is even, turn off the first motor 5 and the second motor 71.

[0037] Embodiment 2

[0038] On the basis of Embodiment 1, as Figure 7 shown, it further includes an anti-sticking mechanism 9 for preventing the mortar from sticking to the inner wall of the mixer. The anti-sticking mechanism 9 includes a first ball rod 91 and a second ball rod 92. The second ball rod 92 is fixedly connected to the outside of the right side of the first frame 4. The first ball rod 91 is fixedly connected to the outside of the upper side of the chassis 3. The upper side of the first ball rod 91 and the lower side of the second ball rod 92 are both semi-cylinders. The second gear 73 rotates to drive the chassis 3 to rotate. Thus, the first ball rod 91 on the chassis 3 rotates accordingly. When the first ball rod 91 contacts the second ball rod 92, the first ball rod 91 squeezes the second ball rod 92 upward, driving the first frame 4 and the second frame 41 to move upward. When the first ball rod 91 passes over the second ball rod 92, the second ball rod 92, the first frame 4 and the second frame 41 reset downward due to gravity. Rotate repeatedly in this way, making the whole of the first frame 4 and the second frame 41 shake, preventing the mortar from sticking.

[0039] As Figure 8 and Figure 9 shown, it further includes an adjusting mechanism 10 for stirring the mortar at the position where it is not evenly stirred. The adjusting mechanism 10 includes a nut 101 and a pushing plate 102. Through grooves 103 are opened on the upper side of the stirring shaft 6. The nuts 101 are slidably connected to the inside of the through grooves 103. The pushing plates 102 are threadedly connected to the upper sides of the nuts 101. The pushing plates 102 can be removed and the positions of the pushing plates 102 can be adjusted, so as to stir the mortar more evenly.

[0040] As Figure 10As shown in the figure, it further includes a scraping mechanism 11 for scraping the mortar on the inner wall of the mixer. The scraping mechanism 11 includes a scraping frame 111 and a scraping iron ring 112. Three scraping frames 111 are evenly and fixedly connected to the inside of the placement frame 2. A scraping iron ring 112 is fixedly connected to the lower ends of the three scraping frames 111. The outer side of the scraping iron ring 112 is attached to the second frame 41. The mortar on the second frame 41 can be scraped off by the shaking of the first frame 4 and the second frame 41.

[0041] As Figures 11-13 shown in the figure, it further includes a limiting mechanism 12 for fixing the position of the feeding port 22. The limiting mechanism 12 includes a clamping shaft 121, a first fixing block 122, a second fixing block 123 and a clamping plate 124. The first fixing block 122 and the second fixing block 123 are fixedly connected to the right side of the placement frame 2. The first fixing block 122 is located above the second fixing block 123. The clamping plate 124 is slidably connected to the right side of the second fixing block 123. A clamping shaft 121 is slidably connected between the first fixing block 122 and the clamping plate 124. A clamping groove 125 is opened on the outer side of the chassis 3.

[0042] During the rotation of the chassis 3, the first cue 91 on the chassis 3 rotates accordingly. When the first cue 91 contacts the second cue 92, the first cue 91 squeezes the second cue 92 upward, so that the first frame 4 and the second frame 41 move upward. When the first cue 91 passes over the second cue 92, the second cue 92, the first frame 4 and the second frame 41 reset downward due to gravity. By rotating repeatedly, the first frame 4 and the second frame 41 as a whole shake repeatedly, so that the connecting rod 81 against the inner wall of the first frame 4 moves upward, driving the swing rod 82 to move upward and slide inward at the same time, making the mortar in the middle more evenly stirred. In this way, the mortar adhering to the inside of the first frame 4 can be shaken off.

[0043] During stirring, the mortar may be unevenly stirred in some places. The push plate 102 can be unscrewed from the nut 101. The push plate 102 leaves the initial through groove 103 position. Move the push plate 102 and the nut 101 to the through groove 103 position corresponding to the mortar to be stirred, and tighten the push plate 102 and the nut 101 so that the push plate 102 and the nut 101 are tightly connected. In this way, the mortar at the position to be stirred can be more evenly stirred.

[0044] When the first frame 4 and the second frame 41 as a whole shake up and down, the scraping frame 111 and the scraping iron ring 112 remain stationary. The outer side of the scraping iron ring 112 is attached to the second frame 41. In this way, the mortar inside the first frame 4 and the second frame 41 can be scraped off by the scraping iron ring 112. At the same time, during the process of mortar stirring, the scraping frame 111 can change the original position of the mortar and play a blocking role on the mortar, making the mortar better mixed.

[0045] After the mortar is stirred evenly, start the second motor 71. The output shaft of the second motor 71 drives the first gear 72 to rotate. The first gear 72 meshes with the second gear 73, so that the second gear 73 rotates, causing the chassis 3 to rotate. When the card slot 125 on the outer side of the chassis 3 is aligned with the groove on the outer side of the placement frame 2, turn off the second motor 71. Move the card shaft 121 upward out of the card plate 124. Align the card plate 124 with the position of the card slot 125 and insert it into the card slot 125, so that the position of the material outlet 22 is communicated with the discharge valve 21. In this way, the chassis 3 can be controlled to remain stable, and the position of the material outlet 22 does not shift. Open the valve to take out the stirred mortar. After taking out the mortar, close the valve.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
