Description

Technical Field

[0001] The present invention relates to the technical field of concrete production, and particularly relates to a concrete mixing and feeding device. Background Art

[0002] Concrete refers to a general term for engineering composite materials in which aggregate is cemented into a whole by a cementitious material. Usually, the term "concrete" refers to cement concrete, which uses cement as the cementitious material, sand and stone as the aggregate; it is mixed with water in a certain proportion and obtained by stirring, and is also called ordinary concrete, and is widely used in civil engineering. In the process of manufacturing electric poles, it is necessary to put concrete into a mold for processing and preparation.

[0003] In the process of concrete production, a certain amount of cement, sand, stone and water need to be mixed in a certain proportion. When the above-mentioned related device transports cement, it cannot perform quantitative transportation. It is necessary to take out the cement from the cement tower, transport it to a weighing device to weigh the cement, and then use a conveying device to transport it to a mixing device to be mixed and stirred with other raw materials. During the weighing process, a large amount of time is consumed, reducing the production efficiency of concrete. Summary of the Invention

[0004] The present invention provides a concrete mixing and feeding device, aiming to solve the problem that in the related technology, when the conveying device transports cement, it cannot perform quantitative transportation, resulting in low production efficiency of concrete.

[0005] A concrete mixing and feeding device of the present invention includes: A base, on one side of which a first conveying mechanism is installed, and on the other side a second conveying mechanism is installed; A telescopic mechanism, installed on the base; A silo mechanism, rotatably installed on the telescopic mechanism. The silo mechanism has a plurality of chambers. The discharge end of the first conveying mechanism faces one of the chambers. The first conveying mechanism is used to convey cement to the corresponding chamber, and the telescopic mechanism shrinks as the cement in the chamber increases; A one-way transmission mechanism, connected to the silo mechanism; An energy storage mechanism, installed on the front and back sides of the base. When the first conveying mechanism conveys cement to the chamber, the energy storage mechanism stores energy; when the cement in the chamber reaches a specified mass, the energy storage mechanism releases energy, and drives the silo mechanism to rotate through the one-way transmission mechanism, so that the cement of the specified mass flows out of the chamber.

[0006] When transporting cement, under the action of the bin mechanism and the gravity of the cement, the telescopic mechanism is compressed and contracted, and at the same time, the bin mechanism moves downward. The downward-moving bin mechanism does work on the energy storage mechanism, causing the energy storage mechanism to store energy. When the cement inside the bin mechanism reaches the specified mass, the telescopic mechanism moves downward to a specified distance. At the same time, the bin mechanism acts on the energy storage mechanism, prompting the energy storage mechanism to release energy and do work on the bin mechanism, driving the bin mechanism to rotate. The rotating bin mechanism further releases the cement inside the chamber, causing the cement to fall into the aggregate bucket, thereby achieving the purpose of quantitatively transporting cement, reducing the process of additional weighing of cement, and improving the production efficiency of concrete.

[0007] Preferably, the telescopic mechanism includes a telescopic member and a support plate. One end of the telescopic member is connected to the base, and the other end of the telescopic member is connected to the support plate. An outlet is provided on the support plate for the cement in the chamber to pass through, and a limiting ring is provided above the support plate.

[0008] According to Hooke's law, it can be known that by setting the telescopic mechanism, the quantitative weighing of cement can be realized, and further the purpose of quantitative transportation can be achieved, improving the production efficiency of concrete.

[0009] Preferably, the telescopic member includes an outer cylinder, an inner cylinder is inserted inside the outer cylinder, and the inner cylinder can move in the vertical direction. A first spring is provided inside the outer cylinder. The upper end of the first spring is connected to the inner cylinder, and the lower end of the first spring is connected to the bottom wall of the outer cylinder. The inner cylinder moving downward in the vertical direction can compress the first spring.

[0010] Preferably, a groove is provided on the upper surface of the limiting ring, and a rolling ball is installed in the groove, and the rolling ball can roll inside the groove.

[0011] By setting the rolling ball, the contact between the fixing plate and the rolling ball is rolling contact, which is converted from sliding friction to rolling friction, facilitating the rotation of the bin mechanism and increasing the flexibility of the system.

[0012] Preferably, the bin mechanism includes a bin. A plurality of partition plates are provided inside the bin, and a plurality of chambers are formed between the plurality of partition plates and the inner wall of the bin. A pressing plate is provided on the outside of the bin; a fixing plate is also provided on the outside of the bin, and the fixing plate abuts against the limiting ring; the bin has a lower end portion, and the lower end portion is in contact with the surface of the support plate.

[0013] By setting a plurality of chambers, it can meet the need for quantitative weighing of cement, can realize continuous operation, and further improve the working efficiency of cement transportation.

[0014] Preferably, the energy storage mechanism includes a fixed housing, inside which there is an airbag. Inside the airbag, there is a return spring. A pressing plate is slidably arranged inside the fixed housing. On the side of the pressing plate away from the airbag, a driving shaft is fixedly arranged. One end of the driving shaft away from the pressing plate penetrates through the fixed housing and extends to the outside, and is connected with a driving block. A second spring is sleeved on the surface of the driving shaft. One end of the second spring is connected with the driving block, and the other end is connected with the fixed housing. The driving block is in contact with the lower end part. When the silo mechanism moves downward, the lower end part drives the driving block to move, and further drives the pressing plate to move through the driving shaft to press the airbag, so that the pressure inside the airbag increases.

[0015] When the silo mechanism moves downward, it presses the airbag, thereby doing work on the airbag to store energy in the airbag, which is convenient for the airbag to do work on the silo mechanism and drive the silo to rotate, achieving the effect of discharging materials from the silo.

[0016] Preferably, a first valve assembly is arranged on the airbag. The first valve assembly is connected with a first cylinder through a connecting pipe. The first cylinder is fixedly installed outside the fixed housing. A one-way valve is also arranged on the airbag. One end of the one-way valve is communicated with the inside of the airbag, and the other end is communicated with the connecting pipe. The flow direction of the gas inside the one-way valve is from the connecting pipe to the inside of the airbag. An operating handle is connected to the first valve assembly, and the operating handle can press the first valve assembly to control the opening and closing of the first valve assembly.

[0017] Preferably, a second valve assembly is arranged at the feeding end of the first conveying mechanism. The second valve assembly includes a housing installed at the feeding end and a second cylinder installed above the base. A baffle is inserted inside the housing. The telescopic end of the second cylinder is connected with the baffle, and the air inlet end of the second cylinder is connected with the connecting pipe.

[0018] By arranging the second valve assembly, the opening and closing of the feeding end of the first conveying mechanism can be controlled, improving the coordination between the first conveying structure and the silo structure.

[0019] Preferably, the one-way transmission mechanism includes a transmission part, a one-way rotating part and a driving part. The one-way rotating part is fixedly sleeved on the periphery of the silo. The transmission part is sleeved on the periphery of the one-way rotating part. The driving part is connected with the telescopic end of the first cylinder, and the first cylinder can drive the driving part to move.

[0020] Preferably, the transmission part is a gear ring, the driving part is a rack, and the one-way rotating part is a one-way bearing.

[0021] The beneficial effects of the present invention are as follows: The first conveying mechanism conveys cement powder into the silo machine. Under the action of the silo mechanism and the gravity of the cement, the telescopic mechanism contracts, and at the same time, the silo mechanism moves downward. At this time, the energy storage mechanism stores energy; when the cement in the silo mechanism reaches the specified mass, the telescopic mechanism contracts to the specified distance. At the same time, the silo mechanism acts on the energy storage mechanism, prompting the energy storage mechanism to release energy and drive the silo mechanism to rotate. The rotating silo mechanism further releases the cement inside the chamber. The second conveying mechanism transports the released cement to the mixing device. This device weighs the cement during the transportation process, realizes the quantitative conveying of the cement, omits the additional weighing process of the cement, and improves the production efficiency of concrete.

Detailed implementation mode

[0035] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention, but should not be construed as limiting the present invention.

[0036] As Figures 1 to 11 shown, a concrete mixing and feeding device of the present invention includes a base 10. A telescopic mechanism 50 is installed on the base 10. A hopper mechanism 40 is rotatably installed on the telescopic mechanism 50. The hopper mechanism 40 has a plurality of chambers 411. A first conveying mechanism 30 is installed on the right side of the base 10. The first conveying mechanism 30 is used to convey materials into the interior of one of the chambers 411. A second conveying mechanism 31 is installed on the left side of the base 10. The second conveying mechanism 31 is used to convey the cement powder inside the chamber 411 to the mixing device. Energy storage mechanisms 20 are installed on both the front and rear sides of the base 10. The energy storage mechanisms 20 are used to store and release energy. When the energy storage mechanisms 20 release energy, they can drive the hopper mechanism 40 to rotate through a one-way transmission mechanism 60, so that the cement flows out of the chamber 411.

[0037] The first conveying mechanism 30 conveys cement powder into the silo mechanism 40. Under the action of the silo mechanism 40 and the gravity of the cement, the telescopic mechanism 50 contracts, and at the same time, the silo mechanism 40 moves downward. At this time, the energy storage mechanism 20 stores energy; when the cement inside the silo mechanism 40 reaches the specified mass and the telescopic mechanism 50 contracts to the specified distance, the energy storage mechanism 20 releases energy to drive the silo mechanism 40 to rotate. After rotation, the silo mechanism 40 further releases the cement inside the chamber 411, and the second conveying mechanism 31 transports the released cement to the mixing device. It should be noted that at this time, the next chamber 411 is facing the first conveying mechanism 30 for subsequent storage of cement; as the cement is released, the mass of the silo mechanism 40 and the cement decreases, the telescopic mechanism 50 extends, and the silo mechanism 40 moves upward to the initial position. Then, the first conveying mechanism 30 transports cement into the silo mechanism 40 to start the next cycle. This device weighs the cement during the transportation process to achieve quantitative conveying of the cement, eliminating the need for additional weighing of the cement and improving the production efficiency of concrete.

[0038] As Figures 3 to 4 shown, the telescopic mechanism 50 includes a telescopic member 54 and a support plate 51. One end of the telescopic member 54 is connected to the base 10, and the other end of the telescopic member 54 is connected to the support plate 51. A discharge port 52 is provided on the support plate 51 for the cement inside the chamber 411 to pass through. A limiting ring 53 is provided above the support plate 51. Specifically, the limiting ring 53 is fixedly connected to the support plate 51 through a connecting rod. The telescopic member 54 includes an outer cylinder 542, and an inner cylinder 541 is inserted into the inside of the outer cylinder 542, and the inner cylinder 541 can move in the vertical direction. A first spring 543 is provided inside the outer cylinder 542. The upper end of the first spring 543 is connected to the inner cylinder 541, and the lower end of the first spring 543 is connected to the bottom wall of the outer cylinder 542. The inner cylinder 541 moving downward in the vertical direction can compress the first spring 543.

[0039] As Figures 5 to 7As shown, the silo mechanism 40 includes a silo 43. Inside the silo 43, there are multiple partition plates 46. The multiple partition plates 46 evenly divide the interior of the silo 43 into multiple chambers 411. On the outside of the silo 43, there is a pressing plate 41. The pressing plate 41 is used to press the energy storage mechanism 20 to release energy. On the outside of the silo 43, there is also a fixing plate 42. The fixing plate 42 abuts against the limiting ring 53, so that the limiting ring 53 can support the silo 43 through the fixing plate 42. The silo 43 has a lower end portion 45. The lower end portion 45 is attached to the surface of the support plate 51, thereby blocking the lower end of the chamber 411, enabling the chamber 411 to hold cement inside. The lower end portion 45 has a frustum-shaped structure, and the diameter of its upper opening is larger than that of the lower opening. When the first conveying mechanism 30 conveys cement to the chamber 411, as the weight increases, the silo mechanism 40 can compress the telescopic mechanism 50 and move downward. The inclined surface of the lower end portion 45 acts on the telescopic mechanism 50 to store energy in the telescopic mechanism 50. When the silo mechanism 40 moves downward to a specified distance, the pressing plate 41 presses the energy storage mechanism 20 to release the energy stored in the energy storage mechanism 20.

[0040] As Figure 1 , 3 , 8, 9 shown, the energy storage mechanism 20 includes a fixed shell. Inside the fixed shell, there is an airbag 24. Inside the airbag 24, there is a return spring. The return spring is used to make the airbag 24 return to its natural state after being released from an external force. A pressing plate 23 is slidably arranged inside the fixed shell. On the side of the pressing plate 23 away from the airbag 24, a driving shaft 22 is fixedly arranged. One end of the driving shaft 22 away from the pressing plate 23 penetrates the fixed shell and extends to the outside, and is connected to a driving block 21. A second spring is sleeved on the surface of the driving shaft 22. One end of the second spring is connected to the driving block 21, and the other end is connected to the fixed shell. The driving block 21 has an inclined surface. The inclined surface of the driving block 21 is attached to the inclined surface of the lower end portion 45. When the silo mechanism 40 moves downward, the lower end portion 45 drives the driving block 21 to move, and further drives the pressing plate 23 to move through the driving shaft 22 to squeeze the airbag 24, so that the pressure inside the airbag 24 increases. At this time, the airbag 24 is in a high-pressure state, and both the second spring and the return spring are in a compressed state; when the silo mechanism 40 moves upward, under the action of the second spring, the pressing plate 23 moves in the reverse direction to reset, releasing the airbag 24. The airbag 24 returns to its natural state under the action of the return spring. It should be noted that the airbag 24 includes a rigid part 241 and a flexible part 242. Among them, the rigid part 241 and the flexible part 242 are in communication with each other, and the flexible part 241 can contact the pressing plate 23.

[0041] As Figure 8 , Figure 10As shown, a first valve assembly 27 is provided on the airbag 24. The first valve assembly 27 is connected to a first cylinder 25 through a connecting pipe 26. The first cylinder 25 is fixedly installed outside the fixed housing. A one-way valve 29 is also provided on the airbag 24. One end of the one-way valve 29 communicates with the inside of the airbag 24, and the other end of the one-way valve 29 communicates with the connecting pipe 26. The flow direction of the gas inside the one-way valve 29 is from the connecting pipe 26 to the inside of the airbag 24, so that the gas inside the first cylinder 25 can flow into the airbag 24 through the one-way valve 29 (for restoring the airbag 24 to its natural state). An operating handle 28 is connected to the first valve assembly 27. The operating handle 28 can press the first valve assembly 27 to control the opening and closing of the first valve assembly 27. When the first valve assembly 27 is in the open state, the airbag 24 in the high-pressure state can drive the telescopic end of the first cylinder 25 to extend, and drive the silo mechanism 40 to rotate through the one-way transmission mechanism 60; conversely, when the first valve assembly 27 is in the closed state, the airbag 24 cannot drive the first cylinder 25.

[0042] As Figure 10 shown, the first valve assembly 27 includes a housing 271. The lower end of the housing 271 has a through hole, so that the airbag 24 communicates with the inside of the housing 271. A sealing cylinder 272 is slidably installed inside the housing 271, and the circumference of the sealing cylinder 272 is sealingly connected to the inner wall of the housing 271. A third spring 273 is also provided inside the housing 271. The lower end of the third spring 273 is connected to the bottom wall of the housing 271, and the upper end of the third spring 273 is connected to the sealing cylinder 272. The lower end of the operating handle 28 passes through the housing 271 and extends into the interior and is connected to the sealing cylinder 272, and the operating handle 28 can drive the sealing cylinder 272 to move vertically inside the housing 271. A second opening 275 is provided on the housing 271, and a first opening 274 is provided on the sealing cylinder 272, and the first opening 274 is located above the second opening 275. When the silo mechanism 40 moves downward, the pressing plate 41 presses the operating handle 28, and the operating handle 28 drives the sealing cylinder 272 to move downward. When the sealing cylinder 272 moves to a specified distance, the first opening 274 is aligned with the second opening 275. At this time, the first valve assembly 27 is in the open state, and the airbag 24 in the high-pressure state drives the telescopic end of the first cylinder 25 to extend; when the first opening 274 is misaligned with the second opening 275, the first valve assembly 27 is in the closed state, and the airbag 24 cannot drive the telescopic end of the first cylinder 25 to extend.

[0043] As Figure 2 、 7, as shown in FIGS. 8, the one-way transmission mechanism 60 includes a transmission member 61, a one-way rotating member 62, and a driving member 63. The one-way rotating member 62 is fixedly sleeved on the periphery of the silo 43, the transmission member 61 is sleeved on the periphery of the one-way rotating member 62, and the driving member 63 is connected to the telescopic end of the first cylinder 25. Thus, the first cylinder 25 can drive the driving member 63 to move. When the silo mechanism 40 moves downward to a specified distance, the driving member 63 contacts the transmission member 61, and the moving driving member 63 drives the transmission member 61 to rotate, further causing the silo mechanism 40 to rotate. When the driving member 63 moves in the reverse direction, the transmission member 61 idles under the action of the one-way rotating member 62. In other words, when the driving member 63 moves in the reverse direction, the silo mechanism 40 remains stationary and does not rotate. In one embodiment, the transmission member 61 is a gear ring, the driving member 63 is a rack, and the one-way rotating member 62 is a one-way bearing; in other embodiments, the driving member 63 is a connecting rod, the transmission member 61 is a circular ring, and the connecting rod and the circular ring are driven by friction, and the one-way rotating member 62 is a one-way bearing or a ratchet structure.

[0044] As Figure 1 , Figure 3 shown, a collecting cylinder 11 is further provided on the base 10. The collecting cylinder 11 is located directly below the support plate 51. The collecting cylinder 11 is used to accommodate the cement flowing out of the chamber 411. The feeding end of the second conveying mechanism 31 is communicated with the collecting cylinder 11, so that the second conveying mechanism 31 can convey the cement inside the collecting cylinder 11. Both the first conveying mechanism 30 and the second conveying mechanism 31 are one of a screw conveying mechanism and a conveyor belt.

[0045] As Figures 1 - 2 shown, a second valve assembly 70 is provided at the feeding end of the first conveying mechanism 30. The second valve assembly 70 is used to control the opening and closing of the feeding end. The second valve assembly 70 includes a housing 71 installed at the feeding end and a second cylinder 73 installed above the base 10. A baffle 72 is inserted into the interior of the housing 71. The telescopic end of the second cylinder 73 is connected to the baffle 72, and the air inlet end of the second cylinder 73 is connected to the connecting pipe 26, so that the airbag 24 can provide a gas source to the second cylinder 73, driving the telescopic end of the second cylinder 73 to extend, and driving the baffle 72 to move to block the feeding end. The structures of the first cylinder 25 and the second cylinder 73 are the same. For the specific structure, refer to Figure 11 shown. This is the prior art, and the specific structure will not be described herein.

[0046] Combined with Figure 12 shown, in order to reduce the friction between the silo mechanism 40 and the limiting ring 53 during rotation, a second embodiment is disclosed on the basis of the first embodiment: The upper surface of the limiting ring 53 is provided with a groove, and a ball 531 is installed in the groove. The ball 531 can roll inside the groove. The fixed plate 42 contacts the ball 531, and the sliding friction is converted into rolling friction, thereby reducing the friction force when the silo mechanism 40 rotates.

[0047] The pressing plate 41 is threadedly connected to the silo 43, and the mass of cement weighed each time by the silo mechanism 40 can be adjusted by adjusting the height of the pressing plate 41 on the silo 43. It is understandable that the lower the height of the pressing plate 41, the less the mass of cement weighed each time by the silo mechanism 40.

[0048] In actual use of the device, the first conveying mechanism 30 conveys cement to one of the chambers 411. As the mass of cement increases, the silo mechanism 40 gradually moves downward. The downwardly moving silo mechanism 40 forces the driving block 21 to move, further causing the extrusion plate 23 to move and squeeze the airbag 24. The pressure inside the airbag 24 increases and is in a high-pressure state. When the mass of cement reaches the specified mass, the pressing plate 41 presses the operating handle 28, and the gas inside the airbag 24 is instantly released. The telescopic end of the first cylinder 25 extends, and the driving member 63 drives the silo mechanism 40 to rotate rapidly through the transmission member 61, so that the cement silo containing cement can be placed in the silo. The mud chamber 411 is directly opposite to the discharge port 52, and cement enters the aggregate barrel 11 through the discharge port 52. The second conveying mechanism 31 conveys the weighed cement in the aggregate barrel 11. At the moment when the gas inside the airbag 24 is released, the second valve assembly 70 switches from the open state to the closed state, so that the first conveying mechanism 30 is in an idling state without conveying cement; as the cement in the chamber 411 is released, the silo mechanism 40 moves upward and resets, and the airbag 24 returns to the natural state under the action of the reset spring, the second valve assembly 70 opens, and the first conveying mechanism 30 conveys cement to the corresponding chamber 411, and so on. The device weighs cement during the transportation of cement, realizes quantitative transportation of cement, eliminates the process of additional cement weighing, and improves the efficiency of concrete production.

[0049] The device can also transport other materials, such as sand and gravel particles, grain seeds and other powdery materials.

[0050] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
