Description

Technical Field

[0001] The utility model relates to the technical field of floor paving, in particular to a paving material feeding device and a paving machine. Background Art

[0002] In the field of floor paving, due to the various different requirements of actual working conditions, such as the significantly different flatness of indoor and outdoor floors, and the significantly different requirements of chemical laboratory floors and highway pavement, floor paving often requires corresponding adjustment of construction processes to ensure uniform paving, especially the flow rate and flow rate of paving materials. In the prior art, the material feeding device is a nozzle, which sprays slurry by pump pressure, and its flow rate and flow rate are controlled by flow meters, control valves, etc. However, the position of the nozzle is relatively fixed, and it is difficult to cover different corners. For construction dead corners and other locations, it will be almost impossible to ensure that the slurry can be paved by "self-leveling". It is often necessary to manually scrape or repair after construction, which undoubtedly increases the labor force. In addition, the participation of manpower also makes it difficult to maintain uniform construction quality and the flexibility of paving is poor.

[0003] A Chinese invention patent (patent application number: 202010629813.2) discloses a paver hopper control system, a paver, and a paver hopper control method. Among them, the paver hopper control system includes: a driving mechanism, which is arranged on the paver, and the driving end of the driving mechanism is connected to the hopper of the paver, which is used to drive the hopper to expand or retract; an image acquisition device, which is arranged on the paver, and is used to collect image information of the hopper, feeding mechanism and feeding vehicle of the paver; a controller, which is arranged on the paver, and the controller is electrically connected to the image acquisition device and the driving mechanism to control the operation of the driving mechanism according to the image information collected by the image acquisition device. Through the technical solution of the present invention, the hopper can be controlled to expand or retract according to the image information, so that the state of the hopper matches the operation process of the feeding vehicle, which can effectively improve the operation accuracy and work efficiency, and reduce the labor intensity of the operator and the dependence on operating experience.

[0004] It can be seen that in the above-mentioned prior art, although an image acquisition device is configured to adapt the hopper status and operation in real time to improve the accuracy and efficiency of the hopper operation, the pouring of the slurry in the hopper is still a fixed-position pouring. It is impossible to adapt to different environmental conditions only by controlling the flow rate and flow rate. The paving at the edge and dead corner positions still cannot be achieved by pouring the hopper, and the overall paving quality is also difficult to guarantee. Utility Model Content

DETAILED DESCRIPTION

[0025] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0026] like Figure 1-3 A paving unloading device is shown, comprising a first bracket 1, a second bracket 2, a unloading mechanism 3, a first driving mechanism 4 for driving the unloading mechanism 3 to move along the paving width direction, and a second driving mechanism 5 for driving the unloading mechanism 3 to move along the paving height. The first driving mechanism 4 is installed on the first bracket 1 and extends along the paving width direction. The first driving mechanism 4 is transmission-connected with the unloading mechanism 3. The second driving mechanism 5 is installed on the second bracket 2 and extends along the paving height direction. The second driving mechanism 5 is transmission-connected with the first bracket 1. The second bracket 2 is provided with a mounting portion 21 for being detachably connected to an external paving machine.

[0027] Through the transmission and linkage of the first driving mechanism 4, the first bracket 1, the second driving mechanism 5, and the second bracket 2, the first driving mechanism 4 can drive the unloading mechanism 3 to make displacement adjustment along the width direction of paving, thereby realizing the feeding adjustment in the width direction of paving, and the second driving mechanism 5 can drive the first bracket 1 to drive the unloading mechanism 3 to make displacement adjustment along the height direction of paving, thereby realizing the feeding adjustment in the height direction of paving, and then the unloading mechanism 3 obtains the displacement adjustment capability in both the paving width and height directions, so that the unloading position of the unloading mechanism 3 is flexibly adjustable, and the unloading mechanism 3 can better align with the dead corners, corners, edges, etc. of the ground to be paved. positions so that the slurry can fall directly at these positions, which is more conducive to ensuring the uniformity of the paved floor, thereby not only improving the paving efficiency and saving labor, but also effectively improving the quality of the floor; and, for more complex working conditions, when applied to a paver, the detachable configuration of the mounting portion 21 can be used to replace mechanisms of different sizes, or discharge port sizes, or different feeding directions, which further greatly improves the flexibility of paving and has strong adaptability. It only needs to adjust the position of the corresponding feeding mechanism 3 and / or replace the feeding mechanism 3 according to the actual working conditions to meet the paving needs, so that the feeding device can be more fully utilized, and the efficiency and benefits are better.

[0028] Among them, the paving width direction is the width direction of the paver body when it is moving, and the paving height direction is the vertical direction relative to the floor. For special terrain, the paving width direction and the paving height direction can be slightly changed, and the corresponding material discharge mechanism 3 can be driven to realize displacement adjustment in a certain two-dimensional plane or three-dimensional space. The material discharge mechanism 3 is a mechanism for receiving slurry and stirring the material for paving. The mounting portion 21 can be configured as a quick-release head or fasteners to realize the detachable connection between the mounting portion 21 and the paver body.

[0029] In this embodiment, the first driving mechanism 4 includes a rotary output mechanism 41, a gear rack mechanism 42 (the rack is not shown in the figure) and a first slide rail mechanism 43. The first slide rail mechanism 43 extends along the length direction of the first bracket 1 and is fixed to the first bracket 1. The gear of the gear rack mechanism 42 is installed on the output shaft of the rotary output mechanism 41, and the rack of the gear rack mechanism 42 is installed on the first bracket 1. The unloading mechanism 3 is slidably matched with the first bracket 1 through the first slide rail mechanism 43, and the rotary output mechanism 41 is fixed to the unloading mechanism 3. Through the transmission of the gear rack mechanism 42, the displacement of the unloading mechanism 3 in the paving width direction can be made more accurate, and reliable transmission is also provided for the unloading mechanism 3.

[0030] In order to improve the structural stability and thus enhance the reliability on the basis of light weight, the unloading mechanism 3 of this embodiment includes a back plate 31 and a silo 32. The back plate 31 is fixed to the back of the silo 32 in a detachable manner, and can be connected and fixed by fasteners such as bolts and nuts. A slider 431 is fixed to the back of the back plate 31, and a track 432 is fixed to the first bracket 1. The track 432 and the slider 431 are slidably matched to form the first slide rail mechanism 43. The configuration of the back plate 31 forms an intermediate medium for connection, and the connection space is larger, which makes the connection between the unloading mechanism 3 and the first bracket 1 easier and improves the adaptability of installation.

[0031] As a preferred embodiment, the rotary output mechanism 41 is a motor, which can be a hydraulic motor or an electric motor, and the motor housing is fixed to the upper part of the back plate 31; the silo 32 is detachably fixed to the lower part of the back plate 31, and the silo 32 is arranged back to back with the motor, thereby making the structure more balanced and further improving the stability and reliability of the connection.

[0032] In order to make the displacement adjustment in the width direction of paving smoother and more reliable and improve the carrying capacity, the first bracket 1 of this embodiment is frame-shaped, and there are more than two rails 432 laid on the frame of the first bracket 1. The sliders 431 are correspondingly configured to slide with the rails 432 one by one. More rails 432 and sliders 431 are more conducive to smooth sliding adjustment, and the unloading mechanism 3 can also carry more and heavier slurry.

[0033] As a further optimization, the paving unloading device 100 of the present embodiment further includes an unloading rack 6 for installing a feeding mechanism, the unloading rack 6 is detachably fixed to the unloading mechanism 3 and is located above the unloading mechanism 3, a feeding port 33 for being opposite to the feeding mechanism is provided at the top of the unloading mechanism 3, and an unloading port 34 is provided at the bottom of the unloading mechanism 3. By combining the unloading rack 6 with the unloading mechanism 3, the structure is made more compact, the slurry delivered by the clinker mechanism will be directly dropped into the feeding port 33, the action is more coherent, efficient and reliable.

[0034] Further, the material unloading rack 6 of this embodiment includes a connecting rod 61 and a chuck 62. One end of the connecting rod 61 is detachably fixed to the unloading mechanism 3, and the other end of the connecting rod 61 is fixedly mounted with the chuck 62. The chuck 62 can clamp feeding mechanisms of different shapes and sizes. Generally, if the feeding mechanism is a pipeline, the chuck 62 can be configured as a clamp. The connecting rod 61 realizes the connection medium between the chuck 62 and the unloading mechanism 3, and can be set as a cantilever beam, so that the unloading rack 6 is suspended above the feeding port 33 of the unloading mechanism 3, so that the unloading mechanism 3 can receive materials more evenly and efficiently.

[0035] Since the feeding mechanism 3 has its own weight, combined with the weight of the slurry, the first bracket 1, and the first driving mechanism 4, in order to better provide the bearing capacity, in this embodiment, as shown in FIG. Figure 2-3As shown, the second driving mechanism 5 includes a linear power output mechanism 51 and a second slide rail mechanism 52. The linear power output mechanism 51 is fixed to the second bracket 2. The output shaft of the linear power output mechanism 51 is connected to the first bracket 1 by transmission. The second bracket 2 is slidably matched with the first bracket 1 along the paving height direction through the second slide rail mechanism 52. Further, the second slide rail mechanism 52 includes a guide column 521 and a guide sleeve 522. There are more than two guide columns 521, and the guide sleeves 522 are correspondingly configured to slide with the guide columns 521 one by one. The guide sleeve 522 is fixed to the first bracket 1, and the guide column 521 is fixed to the second bracket 2. Through the sliding matching mode of the guide column 521 and the guide sleeve 522, the lifting and lowering displacement adjustment stability of the unloading mechanism 3 is better, and then the paving thickness uniformity is better.

[0036] A paving machine of the present embodiment includes a machine body and a paving feeding device 100, wherein the mounting portion 21 is a hook, and the hook is fixed to the machine body. By connecting and fixing the paving feeding device 100 and the machine body by means of a hook, assembly or replacement can be completed simply and efficiently. The machine body can be configured as a fixed base, or as a movable body. Preferably, the hook is configured as a hook, so as to mount the paving feeding device 100, and the paving feeding device 100 locks the hook to the machine body due to its own weight. Accordingly, a hook hole or a hook groove or other structure can be provided on the machine body for fixed matching. After the paving feeding device 100 is installed on the machine body, the paving feeding device 100 spreads the slurry along the moving direction of the machine body through the movement of the machine body, and is adjusted by the displacement of the paving feeding device 100, so that the position of the slurry and the paving thickness can be flexibly adjusted, and the adaptability to the ground is strong.

[0037] The implementation methods of the present invention are not limited to these. According to the above-mentioned embodiments of the present invention, by using conventional technical knowledge and customary means in the field, without departing from the above-mentioned basic technical ideas of the present invention and without conflict, the above-mentioned preferred embodiments may also be modified, replaced or combined in various other forms, and the other embodiments obtained all fall within the scope of protection of the present invention.
