Description

Technical Field

[0001] The present invention relates to the technical field of mixer trucks, and more specifically, to a concrete mixer truck and a control system. Background Art

[0002] Currently, in common concrete mixer trucks, a feed hopper is mostly provided at the feed inlet of the mixing drum to facilitate loading the mixer truck at a concrete mixing plant. However, the structure of the feed hopper moves with the vehicle, increasing the weight and fuel consumption of the concrete mixer truck. At the same time, during the loading process of the concrete mixer truck, it is necessary to manually align the feed hopper with the discharge port of the concrete mixing plant, which is difficult to operate, prolongs the operation time. An improved solution for a concrete mixing plant is provided in the prior art, where the feed hopper is connected to the discharge port of the concrete mixing plant, and the position of the feed hopper relative to the discharge port is movable so that the feed hopper can directly extend into the mixing drum of the concrete mixer truck. However, in this solution, before the feed hopper moves, it is still necessary to manually align the mixer truck with the feed hopper, and when there is a sealing cover at the feed inlet of the mixing drum, the sealing cover needs to be opened in advance. There are still problems such as many operation steps, poor accuracy, time-consuming and laborious operation process, and affecting the loading efficiency. Summary of the Invention

[0003] The present invention aims to at least improve one of the technical problems existing in the prior art or related technologies.

[0004] To this end, an object of the present invention is to provide a concrete mixer truck.

[0005] Another object of the present invention is to provide a control system.

[0006] To achieve the above object, the first aspect of the technical solution of the present invention provides a concrete mixer truck, including: a vehicle body; a mixing drum provided on the vehicle body, and a sealing device is provided at the feed inlet of the mixing drum; a first sensing device provided on the mixing drum to detect the position information of the feeding device of the concrete mixing plant corresponding to the mixing drum; a first controller electrically connected to the sealing device and the first sensing device, and the first controller controls the sealing device to open or close the feed inlet of the mixing drum according to the position information of the feeding device.

[0007] According to the technical solution of the first aspect of the present invention, a concrete mixer truck includes a vehicle body, a mixing drum, a first sensing device, and a first controller. The mixing drum, the first sensing device, and the first controller are mounted on the vehicle body and can move along with the vehicle. The mixing drum is used for mixing concrete. By providing a sealing device at the feeding port of the mixing drum to seal the feeding port, on the one hand, it can prevent the concrete in the mixing drum from splashing out during the mixing process, so as to avoid polluting the environment and at the same time reduce the evaporation of water to avoid affecting the performance of the concrete. On the other hand, it can prevent external dust, sundries, etc. from falling into the mixing drum and generating impurities. Optionally, the shape of the feeding port is circular. By providing a first sensing device on the mixing drum to detect the position information of the feeding device of the concrete mixing plant corresponding to the mixing drum, and by setting a first controller electrically connected to the sealing device and the first sensing device, according to the position information of the feeding device detected by the first sensing device, the sealing device is controlled to open or close the feeding port of the mixing drum. That is, when the position of the power device of the concrete mixing plant corresponding to the mixing drum detected by the first sensing device is at a predetermined position, it means that the relative position of the mixing drum and the feeding device at this time meets the feeding condition. The controller controls the sealing device to open the feeding port of the mixing drum so that the feeding port can be communicated with the feeding device to facilitate the concrete mixing plant to feed concrete into the mixing drum. Through this solution, when the relative position of the mixing drum of the concrete mixer truck and the feeding device of the concrete mixing plant meets the preset conditions, the sealing device of the mixing drum can be automatically opened without manual operation, simplifying the operation steps, effectively reducing the preparation time of the feeding operation, and being beneficial to improving the operation efficiency.

[0008] In addition, the concrete mixer truck in the above technical solution provided by the present invention may further have the following additional technical features:

[0009] In the above technical solution, the sealing device includes: a sealing cover provided at the feeding port of the mixing drum, the sealing cover is movably connected to the mixing drum, and the feeding port of the mixing drum is opened or closed by the movement of the sealing cover relative to the mixing drum; a driving mechanism, the output end of the driving mechanism is connected to the sealing cover to drive the sealing cover to move, and the driving mechanism is electrically connected to the first controller to control the operation of the driving mechanism through the first controller.

[0010] In this technical solution, the sealing device includes a sealing cover and a driving mechanism. The sealing cover is arranged at the feeding port of the mixing drum to seal the feeding port. By movably connecting the sealing cover and the mixing drum, the sealing cover can move relative to the mixing drum, so that the sealing cover can move to different positions to open or close the feeding port of the mixing drum, and corresponding operations can be performed on the sealing cover according to specific needs. By providing a driving mechanism, and the output end of the driving mechanism is connected to the sealing cover, so as to output power to the sealing cover through the output end of the driving mechanism, driving the movement of the sealing cover relative to the mixing drum, and then realizing the opening or closing of the feeding port. By providing that the driving mechanism is electrically connected to the first controller, the first controller can control the operation of the driving device according to the position information of the feeding device of the concrete mixing plant corresponding to the mixing drum detected by the first sensing device, and then drive the movement of the sealing cover to realize the opening or closing of the feeding port. This solution can make the operation of the sealing cover achieve automatic control, without manual judgment and operation, with higher accuracy and operation efficiency.

[0011] In the above technical solution, the sealing cover is rotatably connected to the mixing drum, and the rotation axis of the sealing cover is parallel to the plane where the feeding port is located; the driving mechanism is a telescopic oil cylinder, one end of the telescopic oil cylinder is rotatably connected to the vehicle body, and the other end of the telescopic oil cylinder is rotatably connected to the sealing cover. By the telescopic movement of the telescopic oil cylinder, the sealing cover is driven to open or close the feeding port.

[0012] In this technical solution, by providing that the sealing cover is rotatably connected to the mixing drum, the sealing cover can rotate relative to the mixing drum. Specifically, the rotation axis of the sealing cover is parallel to the plane where the feeding port is located, so that the sealing cover can be turned relative to the feeding port. The driving mechanism is a telescopic oil cylinder. By providing that one end of the telescopic oil cylinder is rotatably connected to the vehicle body and the other end is rotatably connected to the sealing cover, the telescopic oil cylinder can drive the sealing cover to turn away from the feeding port or turn towards the feeding port through telescopic movement, realizing the opening or closing of the feeding port.

[0013] It should be noted that according to the relative positions of the telescopic oil cylinder and the sealing cover, it can be set that when the telescopic oil cylinder extends, it drives the sealing cover to open the feeding port, or it can be set that when the telescopic oil cylinder retracts, it drives the sealing cover to open the feeding port, and the technical effects of this solution can be achieved.

[0014] It can be understood that the telescopic movement of the telescopic oil cylinder is relative. It can be set that the cylinder barrel of the telescopic oil cylinder is rotatably connected to the sealing cover, or it can be set that the piston rod of the telescopic oil cylinder is rotatably connected to the sealing cover.

[0015] In the above technical solution, a driving bracket is provided at one end of the vehicle body close to the feeding port. One end of the driving bracket is fixedly connected to the vehicle body, and the other end of the driving bracket extends towards the feeding port and is correspondingly arranged with the sealing cover. Among them, the cylinder barrel of the telescopic oil cylinder is rotatably connected to the end of the driving bracket far from the vehicle body, and the piston rod of the telescopic oil cylinder is rotatably connected to the sealing cover. The sealing cover is driven to open or close the feeding port through the telescopic movement of the piston rod.

[0016] In this technical solution, a driving bracket is provided at one end of the vehicle body close to the feeding port of the mixing drum for connecting the telescopic oil cylinder. Specifically, one end of the driving bracket is fixedly connected to the vehicle body, and the other end extends towards the feeding port, and the other end of the telescopic oil cylinder corresponds to the feeding port for the convenience of connecting the telescopic oil cylinder. By setting the cylinder barrel of the telescopic oil cylinder to be rotatably connected to the end of the driving bracket far from the vehicle body and the piston rod of the telescopic oil cylinder to be rotatably connected to the sealing cover, the driving bracket can support the telescopic oil cylinder, and the relatively heavy cylinder barrel is directly connected to the driving bracket, so that the cylinder barrel only rotates and does not need to perform linear motion, making the force transmission of the whole telescopic oil cylinder more reasonable and beneficial to extending the service life of the telescopic oil cylinder. Optionally, the rotation axis of the sealing cover is arranged along the tangent direction of the feeding port.

[0017] In the above technical solution, the sealing cover is rotatably connected to the mixing drum, and the rotation axis of the sealing cover is perpendicular to the plane where the feeding port is located. The sealing cover can rotate in a plane parallel to the plane where the feeding port is located, and the feeding port is opened or closed through the rotation of the sealing cover.

[0018] In this technical solution, by setting the sealing cover to be rotatably connected to the mixing drum and the rotation axis of the sealing cover to be perpendicular to the plane where the feeding port of the mixing drum is located, the sealing cover can rotate in a plane parallel to the plane where the feeding port is located, that is, the sealing cover can rotate outward or inward in the radial direction of the feeding port, thereby opening or closing the feeding port, and the sealing cover always remains parallel to the plane where the feeding port is located during the rotation process. This solution can make full use of the space on the side of the mixing drum during the feeding process to prevent the sealing cover from interfering with the feeding device and reduce the influence of the sealing cover on the feeding operation. Optionally, the rotation axis of the sealing cover is arranged at the outer edge of the feeding port, which can reduce the rotation radius of the sealing cover and is beneficial to reducing the space occupation.

[0019] In the above technical solution, the sealing cover includes a first cover body and a second cover body. Both the first cover body and the second cover body are rotatably connected to the mixing drum. Both the first cover body and the second cover body can rotate in a plane parallel to the plane where the feeding port is located, and the rotation directions of the first cover body and the second cover body are opposite. The feeding port is opened or closed through the rotation of the first cover body and the second cover body.

[0020] In this technical solution, the sealing cover includes a first cover body and a second cover body. By setting both the first cover body and the second cover body to be rotatably connected to the mixing drum, the first cover body and the second cover body can rotate relative to the feeding port respectively, which can reduce the space occupied by a single cover body in the open position. Among them, both the first cover body and the second cover body can rotate in a plane parallel to the plane where the feeding port is located, and the rotation directions of the first cover body and the second cover body are opposite, so that the first cover body and the second cover body face opposite directions during rotation, that is, one rotates clockwise and the other rotates counterclockwise, which can prevent interference between the first cover body and the second cover body. Optionally, the rotation axes of both the first cover body and the second cover body are arranged at the outer edge of the feeding port to reduce the rotation radius of the first cover body and the second cover body and reduce space occupation. Further, the rotation axes of the first cover body and the second cover body are coaxial, which is beneficial to simplifying the connection structure and facilitating the setting and connection of the driving device.

[0021] In the above technical solution, the sealing cover is slidably connected to the mixing drum. The sealing cover can slide in a plane parallel to the plane where the feeding port is located, and the feeding port is opened or closed by the sliding of the sealing cover relative to the feeding port.

[0022] In this technical solution, the sealing cover is slidably connected to the mixing drum. Specifically, the sealing cover can slide in a plane parallel to the plane where the feeding port is located, that is, the sealing cover can slide radially outward or inward along the feeding port to open or close the feeding port. During the sliding process of the sealing cover, the sealing cover only needs to perform a linear motion, which is convenient for the power transmission of the driving device. In addition, when feeding into the mixing drum, the sliding of the sealing cover can prevent interference with the feeding device.

[0023] Further, the sealing cover can also include a plurality of cover bodies, and all the plurality of cover bodies are slidably connected to the mixing drum, and the feeding port is opened or closed by the sliding of the plurality of cover bodies in different directions.

[0024] In the second aspect of the technical solution of the present invention, a control system is provided, including a concrete mixer truck according to any one of the first aspect of the technical solutions; a concrete mixing station, and a feeding device is provided at the discharge port of the concrete mixing station. Among them, when the first sensing device in the concrete mixer truck detects the position information of the feeding device, the first controller in the concrete mixer truck controls the sealing device to open the feeding port of the mixing drum.

[0025] According to the technical solution of the second aspect of the present invention, the control system includes the concrete mixer truck and the concrete mixing plant in any one of the technical solutions of the first aspect. A feeding device is provided in the concrete mixing plant to facilitate feeding into the mixing drum of the concrete mixer truck. Among them, the first sensing device of the concrete mixer truck transmits the detected position information of the feeding device to the first controller, and the first controller determines whether the relative position between the mixing drum and the feeding device is in a preset position according to the position information, so as to control the sealing device to open the feeding port of the mixing drum when the relative position between the mixing drum and the feeding device is in the preset position, so that the feeding device can communicate with the feeding port of the mixing drum, and the concrete mixing plant can normally feed into the mixing drum. The control system of this solution can automatically open the sealing device of the mixing drum according to the relative position between the mixing drum of the concrete mixer truck and the feeding device of the concrete mixing plant, without manual operation, simplifies the operation steps, can effectively reduce the preparation time of the feeding operation, and is beneficial to improving the operation efficiency.

[0026] In the above technical solution, the feeding device is movably connected to the concrete mixing plant, the feeding device can move relative to the concrete mixing plant, the feeding device can be electrically connected to the first controller, and the first controller can control the sealing device to open the feeding port of the mixing drum according to the position information of the feeding device detected by the first sensing device in the concrete mixer truck. At the same time, the first controller controls the feeding device to move towards the mixing drum and extend into the mixing drum from the feeding port.

[0027] In this technical solution, by setting the feeding device to be movably connected to the concrete mixing plant, the feeding device can move relative to the concrete mixing plant, so that when the relative position between the mixing drum of the concrete mixer truck and the feeding device is in a preset position, the feeding device can move towards the feeding port of the mixing drum, thereby realizing the communication between the feeding device and the feeding port of the mixing drum, and thus eliminating the need for manual alignment and connection operations between the mixing drum and the feeding device, further simplifying the preparation link of the feeding operation. By setting the feeding device to be electrically connected to the first controller, when the feeding operation is performed, the controller can control the sealing device and the feeding device according to the position information of the feeding device detected by the first sensing device, so that the sealing device opens the feeding port of the mixing drum, and at the same time the feeding device moves towards the mixing drum and extends into the mixing drum from the feeding port, so as to facilitate the concrete mixing plant to feed into the mixing drum. Optionally, the electrical connection between the first controller and the feeding device is a wireless communication connection. This solution can realize the linkage control and operation between the concrete mixer truck and the concrete mixing plant, further simplifies the manual operation links and steps, improves the automation degree of the control system, and is beneficial to improving the accuracy and operation efficiency of the feeding operation process.

[0028] In the above technical solution, a second sensing device is configured to detect the position information of the mixing drum of the concrete mixer truck corresponding to the feeding device; a second controller is disposed in the concrete mixing plant. The second controller is electrically connected to the feeding device and the second sensing device, and the second controller can be electrically connected to the first controller of the concrete mixer truck. Wherein, the feeding device is movably connected to the concrete mixing plant, and the feeding device can move relative to the concrete mixing plant. The second controller can send a control instruction to the first controller according to the position information of the mixing drum of the concrete mixer truck corresponding to the feeding device detected by the second sensing device, so that the first controller controls the sealing device to open the feeding port of the mixing drum. At the same time, the second controller controls the feeding device to move towards the mixing drum and extend into the mixing drum through the feeding port.

[0029] In this technical solution, a second sensing device and a second controller are arranged in the concrete mixing plant. The second sensing device detects the position information of the mixing drum of the concrete mixer truck corresponding to the feeding device and sends the position information to the second controller. When the second controller determines that the relative position between the feeding device and the mixing drum is at a preset position according to the position information detected by the second controller, the second controller sends a control instruction to the first controller, so that the first controller controls the sealing device of the concrete mixer truck to open the feeding port of the mixing drum. At the same time, the second controller controls the feeding device to move towards the mixing drum and extend into the mixing drum through the feeding port, so as to facilitate the concrete mixing plant to supply materials into the mixing drum. Optionally, the electrical connection between the second controller and the first controller is a wireless communication connection. This solution can realize the interlocking control and operation between the concrete mixing plant and the concrete mixer truck, further simplify the manual operation links and steps, improve the automation degree of the control system, and is beneficial to improving the accuracy and operation efficiency of the feeding operation process.
