Description

Technical Field

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

[0002] With the continuous deepening of oil exploration and development work, the oil-bearing rock formations to be explored and exploited are getting deeper and deeper, and the acquisition of crude oil has developed towards deeper target layers. For this reason, it is required that oil perforating charges not only must have more powerful armor-piercing capabilities, but also meet the usage requirements under the condition of large standoff (>10 times the charge diameter). Relevant research shows that to achieve the above usage requirements and penetration effects, the research of perforating armor-piercing charges should reach the technical goals of precise charging, precise processing, and precise assembly, so that the jet formed can strictly maintain its straightness along the axis direction when extending in the given large standoff space. Even if the jet is stretched and broken into discontinuous granular particles, these particles can still continue to move forward along the original straight trajectory and act on the bottom of the hole that has been opened by the leading jet, forming a superimposed effect of penetration depth.

[0003] The essence of precise charging of perforating armor-piercing charges is to improve the charging quality, which is specifically reflected in the improvement of the charging density and its density uniformity. The density of the pressed charge column is directly related to the pressing pressure and temperature, and is also closely related to the pressing process and the physical properties of the explosive (such as explosive crystals, loose bulk density, and mechanical strength of explosive particles). The charging density uniformity (i.e., circumferential density uniformity, radial density uniformity, and axial density uniformity) is also closely related to the initial charging shape and quality, pressing process, etc. According to the classical jet armor-piercing theory, the charging density has an important influence on the armor-piercing power of the jet, and the charging density uniformity has an inestimable influence on the quality of the formed jet and the stability of armor-piercing penetration, and sufficient attention should be paid. At present, it is difficult to perform automatic precise charging when charging perforating charges. Therefore, the utility model proposes an automatic weighing and charging device here.

The constant-volume charging mechanism includes a medicine hopper 1, a metering plate 2, a baffle 3 and a tray 4. A movable metering plate 2 is arranged below the medicine hopper 1. A baffle 3 is arranged below the metering plate 2. A tray 4 is arranged below the baffle 3. A charging leak hole 101 is arranged at the bottom of the medicine hopper 1. A detachable measuring cup 201 is arranged inside the metering plate 2. A blanking through hole 301 is opened on the baffle 3. The bottom of the measuring cup 201 communicates with the blanking through hole 301. A charging container 5 is placed above the tray 4. The charging container 5 corresponds to the blanking through hole 301 above it up and down. One side of the metering plate 2 is connected with a metering plate driver 6. The charging volume can be calculated according to the charging mass and density, and then the corresponding constant-volume measuring cup 201 is selected for weighing and charging. The charging includes two stages, namely the constant-volume weighing stage and the filling stage. In the constant-volume weighing stage, the measuring cup 201 on the metering plate 2 is used to pick up a certain weight of main charge by the method of constant volume. In the filling stage, the baffle 3 remains stationary and the metering plate 2 moves. The measuring cup 201 on the metering plate 2 coincides with the blanking through hole 301 on the baffle 3, and the main charge automatically falls into the charging container 5 in the tray to complete the charging. The charging quality of this device is accurate and the error is small; it can automatically complete the charging work with high work efficiency.

[0029] Please refer particularly to Figure 2 and Figure 3 As shown in the figure, a groove 401 for placing the charging container 5 is arranged above the tray 4. The charging container 5 is detachably placed inside the groove 401. The cross-sectional shape of the charging leak hole 101 is conical.

[0030] Please refer particularly to Figure 2 and Figure 4 The bottom diameter of the measuring cup 201 is less than or equal to the top diameter of the blanking through hole 301, and there are multiple specifications for the measuring cup 201. The volumes of different specifications of the measuring cup 201 are different. A through hole for installing the measuring cup 201 is arranged on the metering plate 2. The measuring cup 201 is placed inside this through hole.

[0031] Please refer particularly to Figure 1, the constant-volume charging mechanism is installed on the machine body frame 7, and the metering plate driver 6 is also fixed on the machine body frame 7. A lifting cylinder 8 is connected to the bottom of the tray 4, and the lifting cylinder 8 is fixed on the machine body frame 7. The tray 4 is fixed to the output end of the lifting cylinder 8.

[0032] An infrared capacity sensing device 9 is provided in the hopper 1 of this application. The infrared capacity sensing device 9 includes a transmitter and a receiver. The transmitter is arranged on one side inside the hopper 1, and the receiver is arranged on the other side inside the hopper 1. When the amount of medicine inside is relatively large, the medicine blocks the receiver from receiving the light emitted by the transmitter. When the amount of medicine inside is relatively small, the light emitted by the transmitter can be received by the receiver, and after receiving, the device performs the capacity alarm work.

[0033] Working principle: Weighing and charging are carried out. The charging includes two stages, namely the constant-volume weighing stage and the filling stage. In the constant-volume weighing stage, the measuring cup 201 on the metering plate 2 is used to pick up a certain weight of the main charge by a constant-volume method. In the filling stage, the baffle 3 remains stationary, and the metering plate 2 moves.
