Description

Technical Field

[0001] This utility model belongs to the field of concrete production technology, and more specifically, it relates to an automatic feeding and weighing device for C45 commercial concrete. Background Technology

[0002] Concrete, often simply called concrete, usually refers to cement concrete, which is made by mixing cement as a binder, gravel and sand as aggregates, and water in a certain proportion. A small amount of admixtures and additives can be added to improve the performance of concrete.

[0003] Based on the above, before producing C45 commercial concrete, it is necessary to weigh out the required raw materials, including cement, fly ash, sand and gravel, and then feed them into the mixer for uniform mixing to complete the concrete production. However, existing feeding machines often cannot accurately weigh out different raw materials, so additional weighing equipment is required. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an automatic feeding and weighing device for C45 commercial concrete, so as to solve the problem that the existing concrete feeding device cannot quantitatively weigh each raw material.

[0005] This utility model provides an automatic feeding and weighing device for C45 commercial concrete, achieved through the following specific technical means:

[0006] An automatic feeding and weighing device for C45 commercial concrete includes storage hoppers and a fixed trough. Five storage hoppers are arranged in an array, each supported by angle iron brackets, the bottoms of which are fixed to a base plate. The bottom of each storage hopper is funnel-shaped and connected to a feeding cylinder via a cylindrical connection; one end of the feeding cylinder is open, and the other is closed. The fixed trough is located below the opening of the feeding cylinder, with a supporting column fixedly connected to its bottom. Two racks are mounted above the fixed trough, and a transport trolley is movably connected to each rack. The transport trolley includes a chute, the bottom of which is rotatably connected to two rotating shafts. Gears are mounted at both ends of the rotating shafts, meshing with the racks. The middle of the rotating shaft... A pulley C is provided, with two belts B wrapped around it. A pulley D is wrapped around the other side of belt B. The rotation center of pulley D is fixedly connected to the shaft of a drive motor. The drive motor is fixedly connected to the bottom of the chute on the same side via a motor mount A. A hydraulic cylinder A is installed at one end of the chute. A slider is fixedly connected to the end of the telescopic rod of hydraulic cylinder A. The slider is slidably connected within the chute. A crankshaft connecting rod is hinged to the slider. The other side of the crankshaft connecting rod is hinged to the bottom of a fixed plate. The fixed plate is folded, with one end hinged to one side of the chute. A mixing hopper is fixedly connected to the fixed plate. A hinged door is provided on one side of the mixing hopper. A sliding frame and a weighing cylinder are provided above the mixing hopper.

[0007] Furthermore, the fixed groove has an inlet for the next mixing process on the side near the hinged door on the mixing hopper, and the height of the inlet is lower than and close to the height of the mixing hopper, which is not shown in the figure.

[0008] Furthermore, a rotating rod is inserted inside the feeding cylinder to form a rotatable connection. A spiral structure is wrapped around the rotating rod. A pulley A is set at one end of the rotating rod. Two belts A are wrapped around the pulley A. A pulley B is wrapped around the other side of the belts A. The rotation center of the pulley B is fixedly connected to the rotating shaft of the reduction motor. The reduction motor is mounted on the mounting bracket. The mounting bracket is fixedly connected to the middle height position of the angle iron bracket.

[0009] Furthermore, the two drive motors driving the two rotating shafts are synchronous motors with the same rotation speed.

[0010] Furthermore, a counterweight plate for balancing the weight is provided on the other side of the slide where the drive motor is installed.

[0011] Furthermore, slide rails are provided on both sides of the mixing hopper; the sliding frame is slidably connected to the slide rails of the mixing hopper via bottom rollers, and one side of the sliding frame is fixedly connected to the end of the telescopic rod of the hydraulic cylinder B, and the hydraulic cylinder B is fixedly connected to one side of the mixing hopper.

[0012] Furthermore, two limiting rods are inserted through the sliding frame, and the limiting rods are along the length of the mixing hopper and fixed above the mixing hopper.

[0013] Furthermore, a notch is opened on one side of the upper part of the sliding frame, and two side support plates are provided on the sliding frame. A weighing cylinder is rotatably connected to the side support plate. The weighing cylinder is located directly below the opening of a feeding cylinder. One side of the weighing cylinder is fixedly connected to the rotating shaft of the flipping motor. The flipping motor is fixedly connected to the side support plate (34) on one side through the motor base B.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model uses multiple sets of storage hoppers and feeding cylinders arranged in an array. The starting of the geared motor drives the internal spiral structure of the feeding cylinder to slowly rotate, sending the raw materials in the storage hopper into the weighing cylinder for precise quantity control. It can sequentially take materials from various coagulation raw materials.

[0016] 2. This utility model uses a weighing cylinder. Raw materials are fed into the weighing cylinder by a feeding cylinder. During this process, the weighing cylinder weighs the input raw materials. Once the raw materials reach the required weight, the tilting motor drives the weighing cylinder to tilt toward the side of the sliding frame with a notch, pouring the raw materials into the mixing hopper. The tilting motor then drives the weighing cylinder back to the upright position. If the amount of raw materials weighed at one time is insufficient, multiple weighings and pouring can be performed until the standard is met. This method can achieve accurate weighing of coagulation raw materials.

[0017] 3. By setting up a sliding frame and hydraulic cylinder B, before each material retrieval is completed and before moving to the next feeding hopper position, the hydraulic cylinder B pushes the sliding frame to move on the slide rail of the mixing hopper via rollers, changing the relative position of the weighing cylinder on the mixing hopper, thus avoiding the accumulation and overflow of raw materials due to repeated pouring into the same position in the mixing hopper.

A crankshaft connecting rod 27 is hinged to the slider 26. The other side of the crankshaft connecting rod 27 is hinged to the bottom of the fixed plate 28. The fixed plate 28 is folded, and one end of the fixed plate 28 is hinged to one side of the slide 16. A mixing hopper 29 is fixedly connected to the fixed plate 28. A hinged door 30 is provided on one side of the mixing hopper 29. A sliding frame 31 and a weighing cylinder 35 are provided above the mixing hopper 29.

[0033] Among them, such as Figure 1 As shown, the fixed trough 13 has an inlet for the next mixing process on the side near the mixing hopper 29 where the hinged door 30 is provided. The height of the inlet is lower than and close to the height of the mixing hopper 29, which is not shown in the figure. After receiving the raw materials from each storage hopper 1, the mixing hopper 29 moves to the side of the mixer, opens the hinged door 30, and pours the raw materials into the inlet for mixing.

[0034] Among them, such as Figure 2 As shown, a rotating rod 6 is inserted inside the feeding cylinder 5 to form a rotatable connection. A spiral structure 7 is wrapped around the rotating rod 6. A pulley A8 is set at one end of the rotating rod 6. Two belts A9 are wrapped around the pulley A8. A pulley B10 is wrapped around the other side of the belts A9. The rotation center of the pulley B10 is fixedly connected to the rotating shaft of the geared motor 11. The geared motor 11 is mounted on the mounting bracket 12. The mounting bracket 12 is fixedly connected to the middle height position of the angle iron bracket 2. The geared motor 11 drives the spiral structure 7 to rotate slowly to send the raw material in the storage hopper 1 into the weighing cylinder 35. During this process, the raw material is shaken evenly in the feeding cylinder 5.

[0035] Among them, such as Figure 3 As shown, the two drive motors 22 that drive the two rotating shafts 17 are synchronous motors with the same speed, ensuring that the gears 18 at both ends of the two rotating shafts 17 rotate synchronously; a counterweight plate 24 for balancing the weight is provided on the other side of the slide 16 where the drive motors 22 are installed.

[0036] Among them, such as Figure 3As shown, slide rails are provided on both sides of the mixing hopper 29; the sliding frame 31 is slidably connected to the slide rails of the mixing hopper 29 via bottom rollers 32, and one side of the sliding frame 31 is fixedly connected to the end of the telescopic rod of the hydraulic cylinder B33, which is fixedly connected to one side of the mixing hopper 29; two limiting rods 38 are inserted through the sliding frame 31, and the limiting rods 38 are along the length of the mixing hopper 29 and fixed above the mixing hopper 29; a notch is provided on one side of the upper part of the sliding frame 31, and two side support plates 34 are provided on the sliding frame 31. A weighing cylinder 35 is rotatably connected to the side support plate 34. The weighing cylinder 35 is located directly below the opening of a feeding cylinder 5. One side of the weighing cylinder 35 is fixedly connected to the rotating shaft of the tilting motor 36, and the tilting motor 36 is fixedly connected to the side support plate on one side via a motor base B37. 34. Feeding cylinder 5 inputs raw materials into weighing cylinder 35. During this process, weighing cylinder 35 weighs the input raw materials until the raw materials reach the required weight. Then, the flipping motor 36 drives the weighing cylinder 35 to flip to the side of the sliding frame 31 with the notch, pouring the raw materials into the mixing hopper 29. The flipping motor 36 drives the weighing cylinder 35 back to the upright position. If the raw materials are not weighed enough at one time, multiple feedings and pourings can be performed until the standard is reached. When the flipping motor 36 is started, the reduction motor 11 should be turned off to stop feeding. Before feeding materials to the next feeding hopper 5 position, the hydraulic cylinder B33 pushes the sliding frame 31 to move on the slide rail of the mixing hopper 29 through the roller 32, changing the relative position of the weighing cylinder 35 on the mixing hopper 29, so as to avoid repeatedly pouring the raw materials into the same position of the mixing hopper 29 and causing it to pile up and overflow.

[0037] The specific usage and function of this embodiment are as follows:

[0038] In this invention, different coagulant raw materials are added to different storage hoppers 1. Initially, the weighing cylinder 35 is directly below the opening of the first set of feeding cylinders 5. The reduction motor 11 is started to drive pulley A8, belt A9, and pulley B10 to rotate, driving the spiral structure 7 to rotate and feeding the raw materials in the first set of storage hoppers 1 into the weighing cylinder 35. During this process, the weighing cylinder 35 weighs the first type of raw material until the raw material reaches the required weight. Then, the tilting motor 36 drives the weighing cylinder 35 to tilt toward the side of the sliding frame 31 with the notch, pouring the raw material into the mixing hopper 29. The tilting motor 36 drives the weighing cylinder 35 back to the upright position. If the amount of raw material weighed at one time is insufficient, multiple weighings and pouring can be performed until the standard is reached. When the tilting motor 36 is started, the reduction motor 11 should be turned off to stop feeding. The drive motor 22 is started to drive pulley C 19. The belt B20 and pulley D21 rotate, driving the gears 18 at both ends of the rotating shaft 17 to rotate. The gears 18 mesh and rotate on the rack 15, driving the material transport vehicle to move to one side along the fixed groove 13 until the weighing cylinder 35 reaches the feeding cylinder 5 of the second set of storage hoppers 1. Repeat the above material taking steps to complete the weighing and taking of the second type of coagulation raw material. Take materials for different raw materials in the same way. Then drive the motor 22 to drive the material transport vehicle to the side close to the mixing mixer, open the hinge door 30, and extend the hydraulic cylinder A25 to make the slider 26 slide in the slide groove 16. The crankshaft connecting rod 27 hinged to the slider 16 rotates around the hinge point. At the same time, the mixing hopper 29 fixed on the fixed plate 28 tilts, pouring all kinds of coagulation raw materials in the mixing hopper 29 into the feed port of the mixer. Start the mixer to mix and stir.
