Description

Technical Field

[0001] The utility model relates to a material blanking and vibrating mechanism and road and bridge construction equipment using the same, belonging to the technical field of road and bridge construction equipment. Background Art

[0002] During construction, concrete paving is the process of surface construction on roads and bridges. The main steps include concrete discharging, spreading, vibrating, and leveling. Typically, each step has a corresponding construction machine.

[0003] The hopper is a crucial component of road and bridge construction machinery, where concrete is temporarily stored and then discharged. After discharge, the concrete needs to be vibrated, typically using a vibrating plate or vibrating rod. Currently, the conventional setup places the vibrating element behind the hopper, which doesn't guarantee timely vibration of the concrete. Furthermore, the vibrating rod is typically positioned vertically, which limits the vibrating effect. Utility Model Content

[0004] The purpose of the utility model is to provide a blanking and vibrating mechanism and road and bridge construction equipment using the blanking and vibrating mechanism to solve the above technical problems.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A material discharge and vibration mechanism comprises a material discharge bin; a plurality of opening and closing plates are arranged on the lower end surface of the material discharge bin to control the opening and closing degree of the material discharge opening; a plurality of vibration rods are arranged at the lower end of the material discharge opening of the material discharge bin; and the vibration rods are arranged horizontally.

[0007] The further improvement of the technical solution of the utility model is as follows: a feeding spiral auger is arranged in the discharge bin; and the vibrating rod is arranged at a distance from the discharge port through the main truss of the equipment.

[0008] The further improvement of the technical solution of the present utility model is as follows: a feeding bin is provided at one end of the lower feeding bin; the feeding bin is communicated with the lower feeding bin; and the feeding spiral auger extends into the feeding bin.

[0009] A further improvement of the technical solution of the utility model is that the opening and closing plate is pushed by the oil cylinder to control the sliding of the opening and closing plate.

[0010] A further improvement of the technical solution of the present utility model is that the lower hopper is arc-shaped or conical.

[0011] A further improvement of the technical solution of the present utility model is that the distance between the vibrating rod and the discharge port of the discharge bin is 20 cm-50 cm.

[0012] A road and bridge construction device uses the above-mentioned material discharge and vibration mechanism; the road and bridge construction device comprises a main truss; and a material discharge bin is installed on the main truss.

[0013] Due to the adoption of the above technical solution, the technical effects achieved by the utility model are as follows:

[0014] The utility model provides a discharge and vibration mechanism with a discharge bin and a vibrating rod. The vibrating rod is directly positioned at the lower end of the discharge port of the discharge bin and is arranged horizontally. This arrangement enables the vibrating rod to vibrate and compact the concrete in a timely manner, ensuring the density of the constructed road. At the same time, it also prevents the accumulation of concrete materials from clogging the discharge port.

[0015] The utility model has a feeding bin at one end of the lower hopper, which is integrally arranged on one side of the lower hopper. A feeding screw auger is provided in the lower hopper and can extend to the feeding bin. The feeding screw auger passes through the lower hopper and the feeding bin to realize the feeding of concrete materials and the feeding of concrete materials to the lower hopper, thus ensuring the subsequent accurate and uniform feeding. This arrangement makes the feeding of concrete materials and the feeding of materials in the lower hopper more convenient and easier to control.

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] In the description of the present invention, it should be noted that the terms "upper", "lower", "inside", "outside", "front end", "rear end", "two ends", "one end", "the other end", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as a limitation on the present invention.

[0025] The utility model relates to a material discharging and vibrating mechanism, a key component of road and bridge construction equipment. Road and bridge construction equipment primarily performs a series of operations, including distributing, vibrating, and leveling concrete, to form a road surface that meets requirements. This vibrating mechanism is particularly suitable for discharging and vibrating UHPC high-performance concrete.

[0026] This device is mainly used for feeding and vibrating. Figure 1-Figure 5 As shown, the device mainly includes a feed bin 1, a feed port is provided on the lower end surface of the feed bin 1, and a plurality of opening and closing plates 2 are provided at the feed port to control the opening and closing degree of the feed port, thereby controlling the amount of material falling and the falling speed. A monitoring sensor is provided at the feed port corresponding to each opening and closing plate 6 to monitor the amount of material falling so that the control system can better control the opening and closing degree of the feed port through the opening and closing plate 6, thereby controlling the paving height and flatness of the road surface. Specifically, the opening and closing plates 2 need to be driven and controlled, usually by correspondingly providing an opening and closing plate pushing cylinder 7 to control the sliding of the opening and closing plates 2. Each opening and closing plate 2 is controlled to slide by its own opening and closing plate pushing cylinder 7. Each opening and closing plate 2 can be individually controlled to open and close and the opening and closing degree, or multiple opening and closing plates 2 can be controlled in linkage.

[0027] Since the discharge silo 1 is of a certain length, multiple monitoring sensors are usually installed. Multiple monitoring sensors are arranged horizontally along the discharge port of the discharge silo 1, and adjacent monitoring sensors are spaced a certain distance apart. After each operation is completed, the machine is promptly flushed to clean the residual material splashed on the surface of the detection sensor to ensure normal use next time.

[0028] Multiple opening and closing plates 2 can be provided, each of which can be controlled individually or in conjunction with each other. This method is more conducive to the control of material feeding during construction. Alternatively, only one opening and closing plate 2 can be provided. In this case, multiple opening and closing plates with coordinated control are required to push the oil cylinder 7 to control the opening and closing plate 2.

[0029] like Figure 2 、 Figure 3 、 Figure 4As shown, a plurality of vibrating rods 3 are provided at the lower end of the discharge port of the discharge hopper 1, and the vibrating rods 3 are provided at a distance from the discharge hopper 1. A plurality of vibrating rods 3 are provided along the length direction of the discharge hopper 1, and the vibrating rods 3 are provided in a horizontal manner, which is suitable for paving construction of road surfaces with a smaller thickness, and the horizontal arrangement of the vibrating rods 3 can expand the vibration area in the horizontal direction. In a specific implementation, the distance between the vibrating rods 3 and the discharge port of the discharge hopper 1 is usually controlled to be 20cm-50cm. The vibrating rods 3 vibrate and compact the concrete, and can vibrate and compact the concrete in time after laying. In addition, it also has the function of preventing the accumulation of concrete materials from clogging the discharge port. This arrangement can vibrate and compact the concrete material in time after the concrete material falls and is paved, thereby improving the vibration effect and ensuring the density of the paved road surface. The horizontally arranged vibrating rods have a large vibration range within the horizontal range and a good effect during vibration, and are particularly suitable for construction road surfaces with a smaller thickness. Figure 2 The main display is from the bottom of the machine, diagonally upward. Figure 4 The side view is intended to show the relative height relationship between the vibrating rod and the opening and closing plate pushing cylinder.

[0030] To enable the vibrating rod to be directly positioned at the discharge port of the hopper, the vibrating mechanism has a horizontal placement, which improves the vibration effect. This placement of the vibrating rod in this machine offers significant advantages over the traditional vertical placement of vibrating rods, making it suitable for UHPC high-performance concrete construction.

[0031] When the device is installed on a road and bridge construction equipment, the road and bridge construction equipment has a main truss 8 , and the vibrating rod 3 is installed on the main truss 8 of the equipment, thereby achieving the spacing distance setting from the lower silo 1 .

[0032] The lower hopper 1 provided in the device is used to buffer the concrete material and to control the concrete material discharge. During construction, it is necessary to continuously add concrete material into the lower hopper 1. Figure 5 As shown, the corresponding setting is that a feeding screw auger 4 is set in the lower silo 1, and the feeding screw auger 4 is driven by a motor. Concrete material is added at one end of the lower silo 1, and the concrete material is transported to the other end by the feeding screw auger 4. Furthermore, a feeding silo 5 can be set at one end of the lower silo 1, and the feeding silo 5 is communicated with the internal space of the lower silo 1, and the feeding screw auger 4 extends into the feeding silo 5. When the lower silo 1 is installed on the road and bridge construction equipment, the feeding silo 5 is located outside the main body of the equipment. In other words, the unloading control range of the lower silo 1 is the construction range of the road surface, and the feeding silo 5 is outside the range of the road surface construction.

[0033] In the specific implementation of the material discharge and vibration mechanism of the present invention, the material discharge bin 1 is preferably set to an arc or cone shape, wherein the cone structure has a large opening at the upper end and a small opening at the lower end, so that the material can fall under the action of its own gravity.

[0034] During operation, the mechanism is used to discharge and initially vibrate concrete materials. Concrete materials are poured into the lower hopper 1 by a cement tanker or pump truck, and then discharged through the discharge port. The discharge port is used to adjust the falling speed of the concrete materials, thereby achieving preliminary control of the road surface thickness. While the materials are discharged, the vibrating rod 3 is vibrated and compacted, and the concrete can be vibrated immediately after the materials are discharged.

[0035] The utility model also discloses a road and bridge construction device, which primarily requires material discharge from a feed bin and vibrating with a vibrating rod. The road and bridge construction device comprises a main truss 8 and a traveling mechanism. The feed bin 1 is mounted on the main truss 1, and the vibrating rod 3 is also mounted on the main truss 1.

[0036] The utility model relates to a material discharge vibration mechanism, which can vibrate the dropped concrete in time by horizontally arranging a vibration rod at the position of the discharge opening of the discharge bin, thereby improving the vibration effect and the road construction quality.

[0037] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
