[0002] Conventionally, concrete refers to cement concrete, also known as ordinary concrete, which uses cement as a gelling material, sand and stone as aggregates, and is mixed with water (which may contain admixtures and additives) in a certain proportion and stirred. It has the characteristics of rich raw materials, low price, and simple production process, so its usage is increasing. At the same time, concrete also has the characteristics of high compressive strength, good durability, and a wide range of strength grades, making it widely applicable.

Detailed implementation manners

[0024] The following uses specific specific examples to illustrate the implementation manners of the present invention. Those skilled in the art can easily understand the other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0025] During the production of concrete, a batching device is needed to mix concrete materials. When the existing batching device stirs the proportioned concrete aggregates, generally, the motor drives the mixing blades to rotate horizontally through the mixing rods, so that the concrete in the mixing tank is mixed along with the agitation of the mixing blades. However, such a mixing method is difficult to mix the upper and lower layers of materials well, greatly increasing the mixing time and reducing the batching speed of concrete.

[0026] To solve this problem, please refer to Figures 1-5 , a concrete batching device, comprising: a frame 10, a mixing tank 11 is arranged on the frame 10, the top of the mixing tank 11 is an open mouth, a support plate 12 is fixedly arranged on the inner top of the mixing tank 11, and multiple groups of material hoppers 13 are fixedly arranged on the frame 10;

[0027] A mixing assembly 40 arranged in the mixing tank 11, and a conveying assembly 50 arranged below the material hopper 13;

[0028] The moving component 30 fixedly arranged on the support plate 12 includes a housing 31 and a first motor 32. The housing 31 is fixedly arranged on the upper end surface of the support plate 12. A round shaft 33 that rotates along its own axis is vertically arranged inside the housing 31. The first motor 32 is fixedly arranged on the top of the housing 31, and the output end of the first motor 32 is drivingly connected to the top of the round shaft 33. A worm 34 is fixedly arranged at the middle of the round shaft 33. A cross bar 35 that rotates along its own axis is horizontally arranged inside the housing 31. A worm gear 36 is arranged on the cross bar 35, and the worm gear 36 meshes with the worm 34. At least one set of eccentric wheels 37 is fixedly arranged on the cross bar 35. A top plate 38 is slidably arranged inside the housing 31. A connecting rod 39 is fixedly arranged on the lower end surface of the top plate 38. The top plate 38 is located above the eccentric wheels 37. The top of the stirring component 40 is slidably connected to the bottom of the round shaft 33, and the end of the connecting rod 39 is connected to the top of the stirring component 40.

[0029] During use, the aggregate in the hopper 13 is conveyed into the mixing tank 11 through the conveying component 50. After adding enough materials, an appropriate amount of water is added into the mixing tank 11. Then the first motor 32 is started. The first motor 32 drives the round shaft 33 to rotate. The round shaft 33 drives the worm 34 and the stirring component 40 inside the mixing tank 11 to rotate. The rotation of the stirring component 40 stirs and mixes the aggregate inside the mixing tank 11. While the stirring component 40 rotates, the worm 34 drives the worm gear 36 to rotate. The worm gear 36 drives the cross bar 35 to rotate. The cross bar 35 drives the eccentric wheels 37 to rotate. Due to the eccentric setting of the eccentric wheels 37 themselves, when rotating, they will push the top plate 38 that fits with them upward, causing it to move upward. The top plate 38 drives the stirring component 40 to rise through the connecting rod 39. When rising to the highest point, because there is no upward thrust, the top plate 38 will descend due to the self - weight of the stirring component 40, so that the bottom of the top plate 38 always fits with the side wall of the eccentric wheels 37. Through the rotation of the eccentric wheels 37, the stirring component 40 continuously moves up and down while rotating, enabling it to better mix the upper and lower layers of materials, thereby improving the mixing speed of the raw materials.

[0030] In the specific implementation process, as Figure 2 and Figure 3 shown, the stirring component 40 includes stirring rods 41 and multiple groups of stirring blades 42. The multiple groups of stirring blades 42 are vertically arranged in a column on the stirring rods 41. Multiple groups of fixing rods 43 are arranged on the stirring rods 41. A scraping plate 44 is fixedly arranged at the end of each group of fixing rods 43. A scraping strip 45 is fixedly arranged on the side of the scraping plate 44 close to the mixing tank 11. The scraping strip 45 fits with the inner wall of the mixing tank 11. The bottom end of the round shaft 33 is inserted into the top end inside the stirring rod 41. The inner wall of the top end of the stirring rod 41 is slidably connected to the side wall of the bottom end of the round shaft 33. The side wall of the top end of the stirring rod 41 is connected to the connecting rod 39.

[0031] During use, the stirring assembly 40 is used to stir the concrete aggregate inside the stirring tank 11. The round shaft 33 drives the stirring rod 41 to rotate, and the stirring rod 41 drives the stirring blade 42 to rotate. When the stirring blade 42 rotates, it stirs the raw materials. When the connecting rod 39 drives the stirring rod 41 to move up and down, the stirring rod 41 drives the stirring blade 42 to rotate and stir while moving up and down, so that the raw materials inside are mixed faster. When the stirring rod 41 rotates, it also drives the fixed rod 43 to rotate, and the rotation of the fixed rod 43 can also perform a certain degree of stirring work. At the same time, it also drives the scraping plate 44 to rotate, and the scraping plate 44 drives the scraping strip 45 to rotate to scrape off the concrete attached to the inner wall of the stirring tank 11.

[0032] In the specific implementation process, as Figure 1 and Figure 5 shown, the conveying assembly 50 includes a conveying cylinder 51 and a second motor 52. The side wall of the conveying cylinder 51 is connected to the outlet of the material hopper 13. One end of the conveying cylinder 51 is open, and the open end of the conveying cylinder 51 faces the stirring tank 11. A screw conveyor 53 that rotates along its own axis is arranged inside the conveying cylinder 51. The second motor 52 is located at the other end of the conveying cylinder 51, and the output end of the second motor 52 is drivingly connected to the screw conveyor 53. The connection between the conveying cylinder 51 and the material hopper 13 is through.

[0033] During use, when raw materials need to be added to the stirring tank 11, the second motor 52 is started. The second motor 52 drives the screw conveyor 53 to rotate. The screw conveyor 53 conveys the raw materials that fall from the outlet of the material hopper 13 into the conveying cylinder 51. Under the rotation of the screw conveyor 53, the raw materials are pushed towards the open end of the conveying cylinder 51, and the raw materials are pushed out of the conveying cylinder 51 and fall into the stirring tank 11. During batching, different aggregates of concrete can be proportioned by adjusting the rotation speed of the second motor 52.

[0034] In the specific implementation process, as Figure 3 and Figure 4 shown, the ratchet assembly 60 arranged inside the worm gear 36 includes a ratchet groove 61 and a disc 62. The ratchet groove 61 is opened inside the worm gear 36, and the ratchet groove 61 is concentric with the worm gear 36. The disc 62 is arranged inside the ratchet groove 61. The disc 62 is fixedly arranged on the cross bar 35. Multiple groups of grooves 63 are opened on the side wall of the disc 62. An elastic member 64 is fixedly arranged at the bottom of the groove 63. A ratchet pawl 65 is hingedly arranged inside the groove 63. One end of the elastic member 64 away from the groove 63 is fixedly connected to the bottom of the ratchet pawl 65.

[0035] During use, when it is necessary to move the stirring assembly 40 up and down to increase the stirring speed, the first motor 32 rotates clockwise, causing the clockwise rotating worm 34 to drive the worm wheel 36 to rotate against the direction of the ratchet groove 61. When the ratchet groove 61 rotates reversely, the pawl 65 is stuck in the tooth groove in the ratchet groove 61 due to the push of the elastic member 64. The elastic member 64 can be a spring piece, so as to push the pawl 65 to move outward from the groove 63, so that it can be stuck in the ratchet groove 61, enabling the worm wheel 36 to drive the disc 62 to rotate through the ratchet groove 61 and the pawl 65. The disc 62 drives the eccentric wheel 37 to rotate through the cross bar 35, so that the stirring assembly 40 can move up and down reciprocally. When the first motor 32 rotates reversely, the pawl 65 will not be stuck in the tooth groove of the ratchet groove 61, so it will not drive the disc 62 to rotate, and thus the stirring assembly 40 will not move up and down reciprocally.

[0036] In a specific implementation process, as Figure 5 shown, an anti-blocking assembly 70 is arranged in the hopper 13. The anti-blocking assembly 70 includes a round rod 71 and multiple groups of baffle plates 72. The round rod 71 is horizontally arranged in the hopper 13, and multiple groups of baffle plates 72 are fixedly arranged on the side wall of the round rod 71. Multiple groups of baffle plates 72 are arranged in an annular array on the round rod 71, and the end of the round rod 71 penetrates through the hopper 13.

[0037] When the conveying assembly 50 continuously conveys the raw materials out of the hopper 13, and the raw materials in the hopper 13 may be stacked due to friction and cannot fall at the outlet, rotate the round rod 71. The round rod 71 drives the baffle plates 72 to rotate, fluctuating the stacked raw materials and destroying the balance of the stacked raw materials inside, so that they can continuously fall to the outlet of the hopper 13.

[0038] In a specific implementation process, as Figure 5 shown, a transmission assembly 80 is arranged between the conveying assembly 50 and the anti-blocking assembly 70. The transmission assembly 80 includes a pair of transmission wheels 81 and a synchronous belt 82. One transmission wheel 81 is fixedly arranged on the output end of the second motor 52, and the other transmission wheel 81 is fixedly arranged on the end of the round rod 71 that penetrates through the hopper 13. The synchronous belt 82 is sleeved on the pair of transmission wheels 81, and a protective cover 83 is arranged outside the pair of transmission wheels 81. The protective cover 83 is fixedly connected to the hopper 13, and the output end of the second motor 52 penetrates through the protective cover 83.

[0039] When the second motor 52 drives the auger 53 in the conveying assembly 50 to rotate, the second motor 52 also drives the transmission wheel 81 to rotate. The two transmission wheels 81 will rotate synchronously due to the synchronous belt 82, so that the second motor 52 can drive the round rod 71 to rotate synchronously while driving the auger 53 to rotate, so that the problem of material stacking will not occur when conveying materials.

[0040] In the specific implementation process, such as Figure 2 and Figure 3 As shown, rollers 381 are provided at the bottom of the top plate 38. The rollers 381 are in contact with the side wall of the eccentric wheel 37, the top plate 38 is in contact with the inner wall of the housing 31, a through groove 382 is provided at the center of the top plate 38, and the round shaft 33 is located in the through groove 382.

[0041] During use, the rollers 381 at the bottom of the top plate 38 reduce the friction with the bottom of the top plate 38 when the eccentric wheel 37 rotates to drive the top plate 38 to move up and down, enabling it to reduce energy loss. The through groove 382 in the middle of the top plate 38 does not affect the rotation of the worm gear 36 and the worm 34 when the top plate 38 moves up and down.

[0042] In the specific implementation process, such as Figure 1 As shown, the frame body 10 includes multiple groups of support columns 14 and multiple groups of support rods 15. The ends of the support rods 15 are fixedly connected to the side wall of the mixing tank 11. The conveying assembly 50 and the hopper 13 are fixedly arranged on the support rods 15, and the tops of the support columns 14 are fixedly connected to the bottoms of the support rods 15 respectively.

[0043] During use, the frame body 10 plays a role in supporting the entire equipment. The support columns 14 make the support of the equipment more stable, and the support rods 15 install, fix, and support the hopper 13 and the conveying assembly 50.

[0044] In the specific implementation process, such as Figure 2 Figure 3 As shown, the stirring rod 41 is located at the center of the mixing tank 11. The stirring rod 41 and the round shaft 33 are arranged coaxially up and down. The top of the stirring rod 41 penetrates through the support plate 12 and the housing 31.

[0045] During use, the stirring rod 41 is at the center of the mixing tank 11, enabling it to drive the stirring blades 42 to fully stir when rotating, reducing the problem of local insufficient stirring. The coaxial arrangement of the stirring rod 41 and the round shaft 33 makes it in a stable state without shaking when driving the stirring rod 41 to rotate.

[0046] In the specific implementation process, such as Figure 1 As shown, a discharge port 16 is provided at the bottom of the mixing tank 11, and a valve 17 is provided at the discharge port 16.

[0047] During use, the discharge port 16 is used to discharge the mixed concrete from the mixing tank 11. After the concrete is stirred and mixed, the valve 17 at the discharge port 16 is opened so that the concrete can be completely discharged from the discharge port 16.

[0048] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
