[0002] Highway engineering refers to surveying, measuring, designing, constructing, maintaining and managing works of highway structures. The highway engineering structures include: roadbeds, pavements, bridges, culverts, tunnels, drainage systems, safety protection facilities, greenbelts, traffic monitoring facilities and other service facilities. In the early stage, the construction and maintenance work is generally operated by using simple tools and manpower or animal power. With the development of the mechanical industry, power machines such as internal combustion engines are widely used in the construction, and various single-purpose machines and joint operation machines appear. The pavement paving machines develop towards automatic on-site processing, improvement of the utilization rate of waste materials, simplification of the process and completion of large power and large machines in one time. In the construction of highways, the processing of concrete is the most important.

[0004] However, the concrete mixing device of the prior art still has the following disadvantages: first, the concrete mixing device of the prior art has a complex structure, and the stirring barrel is hoisted as a whole, which is not stable. With the addition of concrete materials, the weight of the stirring barrel as a whole becomes larger and larger, which has a great safety hazard, and the addition and removal of concrete are not convenient and intelligent. The cylinder body cannot automatically change the inclination angle with the change of the addition amount of concrete materials, different mixing modes cannot be adopted for the mixing operation of different concrete materials, that is, the reasonable utilization of the stirring resources of the concrete materials in the cylinder body cannot be realized. Second: the concrete mixing device of the prior art has a large volume, and it is not convenient to move for the processing of different concrete mixing points or different highway concrete in the mixing field, which is time-consuming and laborious.

[0037] Embodiment 1: as shown in Figures 1-10

[0038] An intelligent highway concrete mixing device, the mixing device comprises a supporting mechanism 1, a barrel 2 and a mixing mechanism 3. The supporting mechanism 1 comprises a supporting frame 11, a limiting plate 12, a spring 13, a clamping plate 14 and a lifting frame 15. As shown in Figure 1 The supporting frame 11 is distributed left and right, wherein the supporting frame 11 comprises a base 111 and a back-shaped frame 112, the base 111 is distributed left and right and located at the bottom. The back-shaped frame 112 is symmetrically arranged in two parts and is arranged at the left and right ends of the base 111. The upper end surface of the back-shaped frame 112 is an inclined structure with the front low and the back high, and the upper end surface is provided with axially distributed sliding grooves 113, the clamping plate 14 is slidably arranged in the sliding grooves 113 and connected through the spring. The inner side of the clamping plate 14 is in engagement with the first gear 43 to rotate; so as to realize the movement of the clamping plate under the deflection movement of the first gear.

[0039] As shown in Figure 9 ​As shown: wherein the chute 113 is also provided with a card slot 114 for limiting the card plate 14, the card slot corresponds to the purpose of use, when the card plate moves to the right side of the chute, synchronously based on the release of the spring extrusion potential, prompting the card plate to move to the card slot at one end, and then forming the carding state of the card plate and the card slot, which corresponds to the unloading state of the barrel. Such carding is the basis for providing sufficient time and stability to speed up unloading.

[0040] Referring to Figure 1 As shown: in this embodiment, the limiting plate 12 is symmetrically arranged on the left and right, and is vertically distributed on the support frame 11. Specifically, the limiting plate is fixedly installed on the upper end face of the back-shaped frame, and the two are fixed by welding connection, forming stable support. The limiting plate 12 is vertically distributed on the support frame 11, and is provided with a limiting groove 121 distributed along the axial direction; for fitting installation of connecting rod. The spring 13 is a plurality of springs, and is arranged on the support frame 11, specifically arranged on the side wall of the chute. The cross section of the card plate 14 is U-shaped structure, and is connected with the spring 13, which can also be that one end of the spring is connected with the baffle, and the contact between the baffle and the card plate is completed through the baffle, and the width of the baffle is equal to the width of the chute. The card plate 14 can move relative to the support frame 11; specifically, the card plate moves in the chute. The lifting frame 15 is a concave structure, which can be deflected and moved with the limiting plate 12, and the plane where the lifting frame 15 is located always keeps vertical with the central axis of the barrel 2; in this way, the inclination of the barrel can be changed, and different stirring modes can be selected.

[0041] Referring to Figure 1 And Figure 2 As shown: in this embodiment, the outer side wall of the front half of the barrel 2 is provided with a threaded portion 23, and the outer end side of the threaded portion is also provided with a baffle ring to prevent the installation ring from moving out of position. The installation ring 41 can rotate along the threaded portion 23. Wherein, the barrel 2 is arranged between the lifting frame 15 and the support frame 11 through the connecting structure 4, the connecting structure 4 includes the installation ring 41, the driving part 42, the first gear 43, the connecting rod 44 and the adjusting part 45. The rear end of the barrel 2 is provided with an opening 21 for unloading. And the inner side wall of the barrel is also provided with uniformly distributed protrusions 22; the protrusions can be columnar, spherical, pyramid and other structures, mainly used for breaking up concrete materials and enhancing the stirring effect of concrete materials, please refer to Figure 3 As shown.

[0042] As Figure 10As shown: The cylinder 2 is equipped with a stirring mechanism 3, and the stirring mechanism 3 rotates in the opposite direction to the cylinder 2. This arrangement enhances the mixing effect and production quality of the concrete material when there is a large amount of concrete material. The stirring mechanism 3 includes a stirring motor 31, a stirring shaft 32, stirring blades 33, and an angle sensor 34. The stirring motor 31 is mounted on the cylinder 2, and the stirring shaft 32 is coaxially mounted on the cylinder 2 and connected to the output shaft of the stirring motor 31. The other end of the stirring shaft is connected to the cylinder through a bracket to ensure sufficient stability. The stirring blades 33 have a spiral structure and are mounted on the stirring shaft 32; this arrangement is used to uniformly mix the concrete material inside the cylinder.

[0043] like Figure 1 As shown: In this embodiment, the tilt sensor 34 is disposed on the outer wall of the cylinder 2, or it can be disposed on the mounting ring, along the central axis of the cylinder. The tilt sensor 34 is electrically connected to the mixing motor 31. The tilt sensor is used to sense the change in the tilt angle of the cylinder, and accordingly, the amount of material in the cylinder can be determined (which can be divided into cases of less concrete material, appropriate amount, more concrete material, etc.). When there is a lot of concrete material in the cylinder 2 and the tilt angle reaches a preset value, the mixing motor 31 is turned on. This situation corresponds to a lot of concrete material in the cylinder, causing the cylinder to tend to be vertical. In this state, simply relying on the rotation of the cylinder is not a good mixing effect, so the mixing motor is turned on to mix inside the cylinder and enhance the uniformity of the concrete material mixing.

[0044] Reference Figure 1 , Figure 6 and Figure 9 As shown: the mounting ring 41 is rotatably mounted on the cylinder 2, forming a mixing state that can rotate relatively but cannot move relatively, and a discharging state that can move relatively. Specifically, as... Figure 1 As shown, in the initial state, the mounting ring is close to the elastic washer. When the drive motor rotates forward, the mounting ring tends to move backward along the threaded portion, continuously compressing the elastic washer. Under the action of the elastic washer, this results in the mounting ring "idling," meaning that while the drive motor drives the cylinder to rotate forward via the meshing gears, the mounting ring remains stationary. This creates a situation where the two can rotate relative to each other but cannot move relative to each other. This state corresponds to the normal mixing state of the concrete material in the cylinder. For the specific structure, refer to [reference needed]. Figure 6 As shown. The unloading process involves the drive motor reversing, causing the mounting ring to move forward along the threaded section. Specifically, the mounting ring remains stationary; the reverse rotation of the drive motor causes the cylinder to reverse, creating relative movement between the cylinder and the mounting ring. As a result, the mounting ring moves to the front edge of the cylinder. Based on the lever principle, during this process, the cylinder gradually changes from a nearly vertical position to an inclined position (lower at the rear and higher at the front), facilitating unloading from the rear opening of the cylinder. See the detailed description below.Figure 9 Further, the convenient and efficient material output is realized.

[0045] Referring to Figure 4 and Figure 8 In this embodiment, the driving member 42 is arranged between the barrel 2 and the lifting frame 15 and is configured to drive the barrel 2 to rotate. Specifically, the driving member 42 comprises a mounting seat 421, a sleeve 422, a sleeve shaft 423, a driving motor 424, a second gear 425 and a third gear 426. The mounting seat 421 is arranged on the mounting ring 41 and is integrally formed with the mounting ring 41. The sleeve 422 is fixedly arranged on the mounting seat 421, and the sleeve shaft 423 is arranged on the lifting frame 15 and is matched with the sleeve 422. The sleeve shaft 423 and the sleeve 422 are movable relative to each other, so that the barrel can be lowered and the inclination angle can be changed when different materials are added.

[0046] In this embodiment, the driving motor is a speed-regulating motor, which can be divided into a first low-speed mode, a second medium-speed mode and a third high-speed mode. Correspondingly, the detection preset values of the inclination sensor are also divided into three levels. Taking the inclination state of the barrel in the initial state as an example, the preset angle X between the barrel and the horizontal plane of the base in the initial state is 20-30 degrees. Therefore, the first detection value of the inclination sensor can be 35-50 degrees, the second detection value can be 50-65 degrees, and the third detection value can be 65-85 degrees. The driving motor is also signal-connected with the inclination sensor. Since the inclination sensor detects the inclination value of the barrel, the reference value corresponding to the addition amount of the concrete material in the barrel is obtained. Therefore, when the highway engineering needs to be repaired or a small amount of concrete material is needed, a small amount of concrete material is added in the barrel, and the inclination sensor corresponds to the first state, so that the driving motor is started in the first low-speed mode. When the concrete material in the barrel is moderate, the inclination sensor corresponds to the second state, and the driving motor is started in the second medium-speed mode. When the concrete material in the barrel is more, the inclination sensor corresponds to the third state, and the driving motor is started in the third high-speed mode. At the same time, the stirring motor is also started.

[0047] In this embodiment, the control mode of the driving motor, the stirring motor and the inclination sensor can be automatically controlled by a PLC controller. The control circuit and working principle of the PLC controller can be realized by simple programming by those skilled in the art, which belongs to the common knowledge in the art. Moreover, the present application is mainly used to protect the mechanical device, so the control mode and the circuit connection will not be explained in detail.

[0048] As Figure 1As shown in the embodiment, the second gear 425 is mounted on the output shaft of the driving motor 424, and the third gear 426 is arranged at the rear half of the barrel 2 and fixed by welding. The second gear 425 and the third gear 426 are kept in engagement to ensure sufficient stirring effect. Figure 3 As shown in the embodiment, the driving member 42 further comprises an elastic washer 427, which is sleeved and mounted on the barrel 2 and located between the third gear 426 and the mounting ring 41. When the driving motor 424 is operated in forward rotation, the mounting ring slips, and there is no relative movement between the barrel and the mounting ring, so that the barrel 2 is driven to rotate synchronously to complete the mixing. When the driving motor 424 is operated in reverse rotation, the mounting ring 41 moves forward along the threaded portion 23 relative to the barrel 2, and actually the mounting ring does not move, and the barrel moves backward, so that the barrel 2 is in a state of high front and low back, which facilitates automatic and rapid unloading through the opening.

[0049] In the embodiment, as shown in the embodiment, Figure 1 As shown in the embodiment, the first gear 43 is matched and mounted on the clamping plate 14, and the connecting rods 44 are distributed left and right and one end is fixedly connected with the first gear 43 and the other end is connected with the mounting ring 41. As shown in the embodiment, Figure 5 As shown in the embodiment, the connecting rod 44 comprises a limiting column 441 and a square shaft 442. The limiting column 441 is arranged on the first gear 43 and has a circular cross section and is adapted to be mounted in the limiting groove 121. The limiting column, the square shaft and the connecting ball are integrally formed. As shown in the embodiment, Figure 4 As shown in the embodiment, one end of the square shaft 442 is connected with the limiting column 441, and the other end penetrates the side wall of the hoisting frame 15 and is slidably connected with the mounting ring 41. The hoisting frame and the square shaft are synchronously deflected. The bearing capacity of the connecting rod is large enough, and the purpose of such arrangement is that after the addition of concrete materials in the barrel, the barrel will have two actions, one is downward movement, and the other is inclination change. Therefore, the corresponding connecting rod will drive the clamping plate to move inward along the sliding groove, and the limiting column will move upward along the limiting groove relative to the base.

[0050] In the embodiment, the adjusting member 45 is configured such that when the addition amount of the concrete material is a preset value M1, the rotating speed of the barrel 2 is forward rotation R1 (corresponding to the first low speed of the driving motor), and the included angle between the barrel 2 and the horizontal plane of the support frame 11 is X1 (corresponding to the detection value of the inclination sensor as the first level). When the addition amount of the concrete material is a preset value M2, M1 < M2, at this time the rotating speed of the barrel 2 is forward rotation R2 (corresponding to the third high speed of the driving motor), and R1 < R2, and the included angle between the barrel 2 and the horizontal plane of the support frame 11 is X2 (corresponding to the detection value of the inclination sensor as the third level), and X1 < X2, and the synchronous stirring mechanism 3 is started and kept at reverse rotation speed R3. In this way, the stirring equipment can intelligently select different stirring modes according to the amount of concrete material in the barrel, so as to realize the requirements of reasonable resource utilization, energy saving and environmental protection.

[0051] As shown in the embodiment, Figure 4and Figure 8 As shown: The adjusting component 45 includes a connecting ball 451 and a compression spring 452. The mounting ring 41 is provided with a sliding groove 411, which consists of two symmetrically distributed sliding grooves. The sliding grooves are arc-shaped, specifically, the two sliding grooves are symmetrical with respect to the mounting base. The sliding groove 411 includes a lower circular groove and an upper square groove. The connecting ball 451 is fitted into the circular groove, and the square shaft 442 is fitted into the square groove. One end of the compression spring 452 is disposed on the inner wall of the sliding groove 411, and the other end is connected to the connecting ball 451. The spring force is sufficiently large, and it is located within the circular groove. The connecting ball 451, square shaft 442, limiting post 441, and first gear 43 are coaxially arranged. This arrangement facilitates the free tilting of the cylinder while maintaining a stable connection. In this embodiment, the mounting ring is sufficiently thick, and the circular groove is provided to allow the connecting ball to slide along the sliding groove while the cylinder is movable. The purpose of setting the square groove is to restrict the square shaft from turning, ensuring that the lifting frame and the connecting rod can move synchronously.

[0052] like Figure 1 As shown: In the initial state, there is no concrete material inside the cylinder. Relying on its own weight, the cylinder is in a position where the rear is higher than the front, with an inclination angle of X (20-30 degrees). In this state, the preset compression of the compression spring is small and can be ignored. Figure 4 As shown, the compression spring is essentially at its original length, and the connecting ball is located at the bottom of the sliding groove. The corresponding sleeve shaft is located inside the sleeve, and the end of the sleeve shaft adopts a T-shaped structure to prevent misalignment. In this state, the positions of the corresponding connecting rod and the first gear are as follows: Figure 1 As shown, the first gear is located inside the clamping plate, and the clamping plate is located at the outer end of the slide groove, that is, the outer end face of the clamping plate is flush with the outer end face of the return frame, and the limiting post of the connecting rod is located at the lower part of the limiting groove.

[0053] like Figure 6 The image shows the mixing state of the drum. There is a large amount of concrete material inside the drum, the tilt sensor reading is at level three, the drive motor is in level three high-speed mode, and the synchronous mixing motor has started. Figure 7 As shown, with a large amount of concrete material added to the cylinder, the cylinder tends to tilt towards "vertical." In this state, the weight of the concrete material further contributes to the significant tilt, and the tilt sensor sends signals to the drive motor and the mixing motor. The drive motor intelligently selects a three-stage high-speed mode, driving the third gear to rotate, which in turn drives the second gear and the cylinder to rotate, accelerating the forward rotation of the cylinder. Simultaneously, the mixing motor starts, reversing relative to the drive motor, causing the mixing shaft and blades inside the cylinder to rotate in the opposite direction. This alternating forward and reverse rotation enhances the mixing efficiency and processing quality of the concrete material.

[0054] In this state, due to the increased weight of the cylinder while the positions of the support frame and the lifting frame remain unchanged, the cylinder will gradually move downward and tilt relative to the support frame. Therefore, the connecting ball will slide along the sliding groove, compressing the compression spring. See the detailed structure for reference. Figure 8 As shown. The connecting ball moves inward along the sliding groove. Since the connecting ball and connecting rod are a single unit, this causes the connecting rod to also move inward, which in turn moves the clamping plate to the inside of the sliding groove. All of these actions correspond to the downward movement of the cylinder. The cylinder completes its movement from its initial state. Figure 7 The tilting action shown also includes: since the lifting frame always remains parallel to the plane where the mounting ring is located, the lifting frame deflects to... Figure 7 At the position shown, that is, the hoisting frame is... Figure 1 State change to Figure 6 In the state shown, the lifting frame rotates clockwise. With the assistance of the square shaft, this causes the first gear to rotate clockwise. The first gear meshes with the clamping plate, causing the clamping plate to move backward along the slide groove, compressing the spring. Figure 6 As shown.

[0055] like Figure 9 As shown, this state represents the unloading state of the cylinder. After the concrete material inside the cylinder has finished mixing, the drive motor reverses, causing the mounting ring to move forward to the front end of the threaded section. Specifically, the mounting ring remains stationary while the drive motor reverses, causing the second gear and the cylinder to reverse. Therefore, there is relative movement between the cylinder and the mounting ring; in reality, the cylinder moves forward until the mounting ring reaches the front end of the threaded section. During this process, based on the lever principle, the cylinder gradually tilts until it becomes a tilted structure with a higher front and lower back, which is the unloading state of the cylinder. During this tilting process (from... Figure 6 Towards Figure 9 (The process of change), the hoisting frame is supported by the central axis of the limit column and begins to deflect counterclockwise. The corresponding first gear rotates counterclockwise, driving the clamping plate to move forward along the slide. At this time, one end of the clamping plate enters the clamping position, completing the clamping operation and providing enough time for the subsequent unloading of the cylinder.

[0056] Example 2: Based on Example 1, a further preferred technical solution: such as... Figure 11As shown: still provided with mobile wheels 16 below the base 111, the mobile wheels 16 are four evenly distributed. And provided with a traction hook on the left side of the base 111. Still provided with telescopic column 17 below the base 111, the telescopic column 17 includes electric hydraulic telescopic rod 171 and support foot 172. The electric hydraulic telescopic rod 171 is arranged vertically on the base 111, the support foot 172 is arranged at the lower end of the electric hydraulic telescopic rod 171, and is made of wear-resistant hard rubber material. Still provided with a control switch on the base, the control switch is electrically connected with the electric hydraulic telescopic rod, so as to be arranged, when the mixing equipment needs to be moved to the next concrete mixing processing site, the electric hydraulic telescopic rod is retracted by operating the control switch until the mobile wheel contacts the ground, which can be moved conveniently, or moved remotely by using a traction device. When the mixing equipment needs to be fixed after moving to the next concrete mixing processing site, the electric hydraulic telescopic rod is extended by operating the control switch until the mobile wheel is separated from the ground, which can ensure the stability of the mixing equipment operation, and the practicality is stronger.
