Description

Technical Field

[0001] The utility model relates to the technical field of soil transmission, in particular to an automatic weighing device for soil transmission. Background Art

[0002] Soil remediation refers to the use of physical, chemical and biological methods to transfer, absorb, degrade and transform pollutants in the soil to reduce their concentration to an acceptable level, or to transform toxic and harmful pollutants into harmless substances. This is to restore the ecological function and health of the soil and ensure that the soil can continue to support plant growth and human activities.

[0003] In the process of soil remediation, a transmission device is needed to transfer the soil to different structures, and it is also necessary to weigh the soil during the soil transmission process. However, the automatic weighing devices for soil transmission on the market often use a robot to grab the soil for weighing during the soil transmission process. This not only has low soil weighing accuracy, but also very low weighing efficiency. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-5, an automatic weighing device for soil transmission, comprising a conveyor belt assembly 1, a lower bin 2 is provided below one side of the material drop end of the conveyor belt assembly 1 through a frame, a lower bin 2 is provided with a lower cavity 21 on the top of the lower bin 2, and a support frame 3 is fixedly provided on one side of the lower bin 2. A weighing plate assembly 4 is movably provided on the support frame 3, positioning members 41 are fixedly provided on both sides of the weighing plate assembly 4, a support member 42 is fixedly provided on the upper side of the weighing plate assembly 4 to one side of the lower bin 2, and a socket 22 is provided on the side wall of the lower bin 2 corresponding to the weighing plate assembly 4.

[0021] The soil can be conveyed to the lower bin 2 by the conveyor belt assembly 1, and then discharged from the bottom of the lower bin 2 after being weighed by the weighing plate assembly 4. It is worth noting that the specific structure and working mode of the conveyor belt assembly 1 and the lower bin 2 are both prior arts, and do not belong to the main technical problems solved in this technical solution, so they are not elaborated in this utility model.

[0022] Among them, a weighing sensor with a weighing module is arranged inside the weighing plate assembly 4, and the model of the weighing sensor is LCD800, and the soil can be weighed through the weighing plate assembly 4. It is worth noting that the specific structure and working mode of the weighing plate assembly 4 are both prior arts, and do not belong to the main technical problems solved in this technical solution, so they are not elaborated in this utility model.

[0023] Among them, a hydraulic rod assembly 5 is installed on the outer side of the support frame 3, and the top extension end of the hydraulic rod assembly 5 is connected to the side wall of the weighing plate assembly 4. The weighing plate assembly 4 can be driven to move by the movement of the top extension end of the hydraulic rod assembly 5. When the top extension end of the hydraulic rod assembly 5 extends outward, it can push the weighing plate assembly 4 from the socket 22 into the feeding cavity 21; when the top extension end of the hydraulic rod assembly 5 contracts inward, it can pull the weighing plate assembly 4 out of the feeding cavity 21 and reset it. The specific structure of the hydraulic rod assembly 5 and its working method are both existing technologies, and do not belong to the main technical problems solved in this technical solution, so they are not elaborated in this utility model.

[0024] Among them, support grooves 24 are provided on both sides of the inner wall of the feeding cavity 21 adjacent to the socket 22, and the support grooves 24 are adapted to the support member 42. A positioning groove 23 is provided on the inner wall of the feeding cavity 21 on the side opposite to the socket 22, and the positioning groove 23 is adapted to the positioning member 41. By setting the positioning groove 23 and the support groove 24, when the weighing plate assembly 4 is located inside the feeding cavity 21, the weighing plate assembly 4 can be supported, thereby improving the stability of the weighing plate assembly 4 when supported. And because the bottoms of the positioning groove 23 and the support groove 24 are both inclined, it is not easy for soil to accumulate in the positioning groove 23 and the support groove 24.

[0025] Among them, the outer side of the unloading bin 2 is fixedly provided with a guide track 6 on the support frame 3, and the guide track 6 is located on both sides of the socket 22. Through the setting of the guide track 6, the weighing plate assembly 4 drawn out from the unloading cavity 21 can be positioned.

[0026] Among them, a guide groove 61 is provided in the guide track 6 corresponding to the support groove 24, and a limiter 62 is provided at the end of the guide track 6. The guide groove 61 is connected with the support groove 24, and the limiter 62 is provided to prevent the weighing plate assembly 4 from being pulled out too much from the feeding cavity 21 and causing the soil to leak from the socket 22. When the weighing plate assembly 4 is completely pulled out, its side wall with the positioning member 41 should completely block the socket 22.

[0027] In this embodiment, when the user needs to transfer and weigh the soil, the soil can be transferred by the conveyor belt assembly 1, and then the soil falls into the lower material cavity 21 in the lower material bin 2. When the soil falls into the lower material cavity 21, due to the setting of the weighing plate assembly 4, the soil will fall on the weighing plate assembly 4. At this time, the conveyor belt assembly 1 stops working, and the soil can be weighed by the weighing plate assembly 4. After the soil is weighed, the weighing plate assembly 4 can be pulled out of the socket 22 by the hydraulic rod assembly 5. When the weighing plate assembly 4 moves outward, the support members 42 on both sides thereof will gradually move from the support groove 24 to the guide groove 61, so that it can be guided by the guide groove 61. And by the setting of the limiter 62, the maximum moving distance of the weighing plate assembly 4 can be limited. When the weighing plate assembly 4 is pulled out, the weighed soil can be unloaded, and the soil falls from the bottom of the lower material bin 2.

[0028] Furthermore, after unloading is completed, the weighing plate assembly 4 is pushed into the unloading cavity 21 again by the hydraulic rod assembly 5. When the weighing plate assembly is located in the unloading cavity 21, the positioning member 41 and the supporting member 42 of the side wall are both clamped in the positioning groove 23 and the supporting groove 24, thereby improving the stability of the weighing plate assembly 4, so that the soil can be weighed stably. Finally, the conveyor belt assembly 1 is controlled to work, so that the soil can be dropped onto the weighing plate assembly 1 again for weighing.

[0029] In the utility model, soil can be transported by the conveyor belt assembly 1. After the transport is completed, the soil falls onto the weighing plate assembly 4 in the discharge chamber 21 for weighing. After the weighing is completed, the soil is discharged by pulling out the weighing plate assembly 4. This method not only has a high weighing efficiency, but also can improve the stability of the weighing plate assembly 4 during weighing through the setting of the positioning member 41 and the support member 42, thereby improving the weighing accuracy.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
