In some embodiments, the above-described feature weighing assembly may take the configuration shown in fig. 7 and 10. Referring to fig. 7 and 10, the weighing assembly comprises a lower bin 6, an upper bin 7, two middle bins 8, two closure elements 63, two feeding units 73, two weighing units, two central controllers 91 and a coordination controller 92.

The lower bin 6 is disposed within the receiving chamber 21 above the outfeed assembly 3, with a lower chamber 61 opening upwardly.

The bottom surface of the lower bin 6 is provided with a lower outlet 62, and the lower outlet 62 is suitable for being communicated with the packaging element 311; in the present embodiment, the inner bottom surface of the lower chamber 61 adopts a top-to-bottom necking structure, and the lower outlet 62 is located at the center of the necking structure.

The upper bin 7 is arranged in the lower chamber 61 in a sliding way along the up-down direction, and is connected with a vertical driving piece 72 for driving the upper bin 7 to move along the up-down direction; in this embodiment, the vertical driving member 72 is two linear driving cylinders or motors arranged along the left-right direction of the vehicle body 1, so as to achieve the technical purposes of supporting the upper bin 7 and driving the upper bin 7 to lift.

The upper bin 7 has an upper chamber 71 open upwardly and adapted to communicate with the upper end of the feed assembly 5, and outside sand can be fed into the upper chamber 71 through the feed assembly 5.

The two middle bins 8 are fixedly arranged on the bottom surface of the upper bin 7 and are suitable for moving into the accommodating cavity 21 so as to reduce the vertical height of the weighing assembly, and are also suitable for moving out of the accommodating cavity 21 so as to ensure that the inner space of the accommodating cavity 21 can be applied to the actual use process.

Each intermediate bin 8 has an inner cavity 81 and the bottom surface of each intermediate bin 8 has an intermediate outlet 82.

The two sealing elements 63 are arranged in one-to-one correspondence with the two middle bins 8, and the sealing elements 63 are arranged on the inner side wall of the lower chamber 61 and are used for sealing the corresponding middle outlets 82; specific:

the closure element 63 has a closed state and an open state;

when the sealing element 63 is in the closed state, the sand in the middle bin 8 is concentrated in the inner cavity 81;

with the closure element 63 in the open condition, sand within the intermediate bin 8 is output downwardly along the intermediate outlet 82.

The two feeding units 73 are arranged in one-to-one correspondence with the two middle cabins 8 and are used for communicating the upper cavity 71 with the corresponding inner cavity 81; specific:

when the feeding unit 73 is in an open state, sand in the upper bin 7 can enter the corresponding middle bin 8;

with the feed unit 73 in the closed state, sand in the upper bin 7 cannot enter the corresponding middle bin 8.

Specifically, when the sealing element 63 is in the closed state and the feeding unit 73 is in the open state, the weighing unit is in the working state; the purpose of this description is not limited to the specific arrangement of the weighing unit, and it may be fixedly arranged on the inner wall of the inner cavity 81, or may be arranged to move with any element.

The two weighing units are arranged in one-to-one correspondence with the two middle bins 8, can preset values and are used for monitoring the weight of sand in the corresponding inner cavity 81; when the monitored value is equal to the preset value, the weighing unit can send out an electric signal.

The two central controllers 91 are arranged in one-to-one correspondence with the two middle cabins 8, and are respectively and fixedly connected to the outer walls of the corresponding middle cabins 8 for users to observe and control.

The central controller 91 is electrically connected to the corresponding sealing element 63, the corresponding feeding unit 73 and the corresponding weighing unit; to achieve the following functions: when the value obtained by the weighing unit reaches the preset value, the corresponding central controller 91 controls the opening of the sealing element 63 and the closing of the feeding unit 73 until the sand is completely discharged to the lower bin 6.

Although the concept of "until the sand is completely discharged to the lower bin 6" is mentioned here, the present invention is not limited to the case where the weight of the sand in the middle bin 8 or the lower bin 6 is always monitored when the sand is discharged from the middle bin 8. In this embodiment, the technical means for realizing complete discharge of sand soil is as follows: the central controller 91 controls the opening of the sealing element 63 and the closing thereof after a period of time, which can be preset according to the amount of sand to be transferred, and can be prolonged appropriately when the amount of sand to be transferred is large; when less sand is required to be transferred, the time can be properly shortened.

It should be further noted that, the time required for two steps of sand input from the upper bin 7 to the middle bin 8 and sand input from the middle bin 8 to the lower bin 6 is related to the specification of the middle bin 8, specifically:

defining the communication part between the middle bin 8 and the feeding unit 73 as a connection port, and when the connection port is larger than the middle outlet 82, sand can quickly fill the middle bin 8, but more time is consumed for discharging; during this process, the other intermediate bin 8 will also fill up quickly, resulting in sand being deposited on the upper bin 7 and not being able to enter the intermediate bin 8.

Similarly, when the connection port is smaller than the middle outlet 82, a lot of time is consumed for the sand to enter the middle bin 8, but the sand is quickly discharged into the lower bin 6, so that after one middle bin 8 discharges the sand, the other middle bin 8 does not complete the unexpected condition of the feeding step, and thus the sand required by the discharging assembly 3 is not timely supplied.

Therefore, in this embodiment, as shown in fig. 10, the optimal specification of the middle bin 8 is that the size of the connecting port is the same as that of the middle outlet 82, so that the time required for feeding and discharging the middle bin 8 is approximately the same, and the technical purpose that one middle bin 8 completely discharges sand and the other middle bin 8 can participate in the sand discharge step in time is achieved.

The coordination controller 92 is electrically connected with the two sealing elements 63 to monitor the use states of the two sealing elements 63; specifically, while one of the closure members 63 is in the open state, the other closure member 63 is maintained in the closed state by the coordination controller 92. At this time, if the sand in the middle bin 8 corresponding to the sealing element 63 kept in the closed state reaches the standard (that is, the weighing element corresponding to the middle bin 8 sends a signal to the central controller 91), the central controller 91 still can receive the signal and control the corresponding feeding unit 73 to be adjusted to the closed state, but the central controller 91 cannot control the opening of the sealing element 63, and only when the other sealing element 63 is converted from the open state to the closed state, the control can be realized.

That is, the coordination controller 92 has a higher priority than the central controller 91, and this process can be implemented by a control system programming manner, and the principle thereof will not be described herein.

During actual use, sand is conveyed into the upper bin 7 from low to high through the feeding component 5, then the sand is divided into two middle bins 8 through the upper bin 7, and the weight of the sand in the middle bins 8 is monitored by the weighing unit, so that the weighing purpose is achieved; the sand output by one of the middle bins 8 is concentrated through the lower bin 6, and the sand is discharged to the discharging assembly 3, so that the discharging purpose is realized. Specifically, the sand conveying step by using the conveying system provided by the application is as follows:

firstly, adjusting the use states of the feeding unit 73, the weighing unit and the sealing element 63, so that the feeding unit 73 is in an open state, the weighing unit is in a working state, and the sealing element 63 is in a closed state; and, the upper bin 7 is moved from bottom to top to a high position by the vertical drive 72.

Then, sand is conveyed into an upper bin 7 at a high position from a low position through a feeding component 5, the sand in the upper bin 7 gradually enters two middle bins 8, two weighing units corresponding to the two middle bins 8 obtain reading changes at the same time, and the reading is compared with a preset value of the weighing units;

finally, when the value obtained by one of the weighing units is the same as the preset value, the weighing unit transmits a signal to the corresponding central controller 91, and the central controller 91 receives the signal and controls the corresponding sealing element 63 to be opened and the corresponding feeding unit 73 to be adjusted to be in a closed state, so that sand is input into the lower bin 6 and flows to the discharging assembly 3.

After the sand in the middle bin 8 is discharged, the central controller 91 controls the sealing element 63 to be closed and the feeding unit 73 to be adjusted to be in an open state, so that the middle bin 8 is put into the weighing step again; at the same time, the other intermediate bin 8 is still in the weighing step, i.e. remains in operation, while the above steps take place.

When one of the middle bins 8 discharges materials to the lower bin 6, if the weighing unit of the other middle bin 8 also transmits a signal that the sand weight reaches a preset value to the corresponding central controller 91, the coordination controller 92 participates in and restricts the opening of the sealing element 63 corresponding to the middle bin 8; that is, after receiving the signal, the central controller 91 only closes the sealing element 63, thereby preventing sand from continuing to enter the middle bin 8; but without opening the closure element 63, so as to avoid uneven sand transport caused by simultaneous discharge of the two intermediate bins 8.
