Detailed Description

The utility model is described below with reference to the accompanying drawings.

Fig. 1 illustrates a paving machine hopper automatic folding device 100 according to one embodiment of the present disclosure. As shown in fig. 1, the automatic folding device 100 for a hopper of a paving machine includes a control mechanism 1. The control mechanism 1 includes a skip guide member 10 provided on a skip 15. The guide member 15 can control the forward speed of the skip car and the bucket lifting or bucket lowering operation of the loading platform 16 on the skip car 15 as required, and maintain the bucket lifting or bucket lowering state.

Meanwhile, the control mechanism 1 further comprises a hopper guide member 20 arranged on the paver 25, and the hopper guide member 20 can control the hopper opening and closing actions of the paver 25 as required and enable a hopper 26 of the paver to keep an open hopper state or a closed hopper state.

In addition, the control mechanism 1 further includes an arithmetic processing device 30 provided on the paver 25. The arithmetic processing unit 30 communicates with the skip car guide member 10 and the hopper guide member 20 at the same time, so that the arithmetic processing unit 30 can issue a command to the skip car guide member 10 and the hopper guide member 20 to control the skip car guide member 10 and the hopper guide member 20 to maintain the corresponding states or perform the corresponding operations under different conditions.

As shown in fig. 1, the automatic hopper folding device 100 further includes a monitoring mechanism 2 disposed on the spreading machine 25. The monitoring mechanism 2 includes a skip monitoring component 40, and the skip monitoring component 40 can monitor the position of the skip 10 and the amount of the material remaining in the loading platform 16 of the skip 15 and transmit the position information of the skip 15 and the information of the material remaining in the loading platform 16 to the arithmetic processing unit 30.

Meanwhile, the monitoring mechanism 2 further includes a hopper monitoring member 50 provided on the paver 25. The hopper monitoring means 50 is capable of monitoring information on the amount of the remaining material in the hopper 26 and transmitting the information on the amount of the remaining material in the hopper 26 to the arithmetic processing unit 30.

In a preferred embodiment, the skip monitoring means 40 are provided as a distance sensor 42 and a first height sensor 44. The distance sensor 42 is capable of monitoring the distance between the paver 25 and the skip 15. The position of the skip 15 relative to the paver 25 can be confirmed by the distance between the two. The first height sensor 44 is capable of monitoring the height of the material remaining within the bed 16 of the truck 10. It will be readily appreciated that the amount of material remaining in the container 16 may be indirectly derived by monitoring the level of material remaining in the container 16.

Similarly, the hopper monitoring member 50 is provided as a second height sensor 55. The second level sensor 55 is capable of monitoring the level of material remaining in the hopper 26 and hence the amount of material remaining in the hopper 26.

In the present invention, the arithmetic processing device 30 is provided as a control software capable of analyzing and arithmetic processing data. After obtaining the remaining material information and the position information fed back from the skip car monitoring means 40 and the hopper monitoring means 50, the arithmetic processing unit 30 can analyze the information and issue a command to the skip car guide means 10 and the hopper guide means 20 to control the skip car guide means 10 and the hopper guide means 20 to perform a corresponding operation or maintain a corresponding state. This process will be described in detail below.

When the material heights monitored by the first height sensor 44 and the second height sensor 55 are simultaneously higher than the preset threshold value, that is, the number of the remaining materials in the container 16 of the skip 10 and the number of the remaining materials in the hopper 26 are simultaneously higher than the preset value, the arithmetic processing unit 30 can issue a control instruction, so that the skip 10 is in a bucket descending state, and the hopper 26 is in a bucket closing state. At this time, the material surplus in the hopper 26 and the carriage 16 is sufficient, and the paver is in a normal working state.

When the material height monitored by the first height sensor 44 is higher than a preset threshold value and the material height monitored by the second height sensor 55 is lower than the preset threshold value, the arithmetic processing unit 30 can issue a control command so that the skip car 10 performs a skip lifting operation and is in a skip lifting state, and the hopper 26 performs a skip opening operation and is in a skip opening state. At this time, the material allowance in the carriage 16 is sufficient, the material allowance in the hopper 26 is insufficient, and the paver is in a charging state. It is easy to understand that the quantity of single feeding can be accurately controlled by setting the feeding time. After the feeding is finished, the arithmetic processing device 30 can control the skip car 15 to perform the bucket descending action and control the skip bucket 26 to perform the bucket closing action, so that the paver returns to and keeps the first state.

In a preferred embodiment, an alarm device 28 is further arranged on the paver, and the alarm device 28 is communicated with the arithmetic processing device 30. When the material of the first height sensor 44 is lower than a preset threshold value, that is, the remaining amount of the material in the container 16 is lower than a set value, the arithmetic processing unit 30 can send an instruction to the alarm device 28, control the alarm device 28 to send an alarm, and remind an operator to supplement the material in the skip 15 or replace the skip.

The height thresholds set by the first height sensor 44 and the second height sensor 55 may be the same threshold or different thresholds, and the operator may freely set the thresholds according to the needs of the field, which is not limited herein.

Meanwhile, the amount of the remaining material in the hopper 26 and the container 16 may be monitored by other sensors (e.g., gravity sensors), and the type of the sensor is not limited in the present invention.

On the other hand, when the distance sensor 42 feeds back information on the distance between the skip 15 and the paver 25 to the arithmetic processing device 30, the arithmetic processing device 30 can analyze the distance. Therefore, in the process of butt joint of the skip car and the paver, the operation processing device 30 can adjust the moving direction of the skip car 15 according to the information fed back by the distance sensor 42, finish the butt joint of the skip car 15 and the paver 25 by controlling the forward and backward movement of the skip car 15, and ensure that the relative distance between the carriage 16 of the skip car 15 and the hopper 26 of the paver 25 is always kept in a reasonable range, so that the material is prevented from spilling when the skip car is fed, and the waste of resources is avoided.

As shown in fig. 1, in a preferred embodiment, the automatic hopper folding device 100 further includes a vertical rod 60 disposed on a side of the paver 25 adjacent to the skip 15. The first height sensor 44, the second height sensor 55 and the distance sensor 42 are all arranged on the vertical rod 60 at the same time. This simplifies the structure of the paver 25 and improves the level of integration of the paver 25, and also simplifies the data transmission line. Preferably, the first elevation sensor 44, the second elevation sensor 55 and the distance sensor 42 are arranged at the level of the upper side 1/3-1/4 of the upright, so that the sensors and the data transmission line are prevented from blocking the line of sight of the staff inside the paver 25.

The operation of the automatic hopper folding device 100 for a paving machine according to the present invention is briefly described as follows.

The automatic hopper stowing device 100 of the paver of the present invention is intended to be mounted on the paver 25. During the paving operation of the paving machine 25, the first height sensor 44 and the second height sensor 55 can monitor the amount of the remaining materials in the skip 15 and the hopper 26 respectively in real time and feed the amount of the remaining materials back to the operation processing device 30. The arithmetic processing unit 30 can analyze data in real time and control the corresponding operations of the skip car guide member 10 and the hopper guide member 20 or maintain the corresponding states.

When the heights of the remaining materials in the hopper 26 and the carriage 16 are higher than the set threshold value at the same time, the arithmetic processing device 30 can send an instruction to enable the skip car 10 to be in a bucket descending state, and enable the hopper 26 to be in a bucket closing state; when the material monitored by the first height sensor 44 is higher than a preset threshold value and the material height monitored by the second height sensor 55 is lower than a preset threshold value, the arithmetic processing unit 30 can issue an instruction to cause the skip car 10 to perform a bucket lifting operation, and the hopper 26 performs a bucket opening operation to replenish the material in the hopper 26. After the completion of the material replenishment, the arithmetic processing device 30 can cause the hopper 26 to resume and maintain the bucket-closing state, and cause the skip 15 to resume and maintain the bucket-lowering state.

Similarly, the distance sensor 42 can monitor the distance between the skip 15 and the paver 25 and transmit the distance to the arithmetic processing device 30, so that the arithmetic processing device 30 can send out an instruction to the feeder car guide member 10. Thus, the distance between the skip car 15 and the paver 25 may be maintained within a set range by controlling the forward speed of the skip car 10.

Finally, it should be noted that the above-mentioned embodiments are only preferred embodiments of the present invention, and do not limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing examples, or that equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
