Description

Technical Field

[0001] The utility model relates to the technical field of pyrotechnic agent weighing, in particular to an explosive weighing device. Background Art

[0002] The explosive is a sensitive explosive that can burn and quickly turn into detonation under the action of weak external excitation energy (such as mechanical, thermal, electrical, and optical). Therefore, the requirements for the amount of explosive added are very strict. At present, the weighing and pouring of explosives in the prior art, such as the Chinese utility model patent "Patent Publication No.: CN113654629A, Name: A Contactless Explosive Metering Device", includes a feeding mechanism, a material distribution mechanism, a material receiving and conveying mechanism, a medicine box, and a weighing mechanism. Among them, the feeding mechanism is an openable and closable raw material packaging mechanism, which is arranged above the material distribution mechanism, and a sufficient distance is maintained between the two. The material distribution mechanism is a funnel-shaped mechanism, and its lower outlet is located above the material receiving and conveying mechanism, and a gap is maintained between the two. The bottom of the material receiving and conveying mechanism is provided with an inclined downward transmission channel, which is connected to the vibration mechanism, and the transmission channel outlet is located above the medicine box and maintains a distance from the medicine box. The medicine box is arranged above the weighing mechanism. This technology has the following disadvantages:

[0003] The dosage of explosive is required to be very precise. During the material distribution and transmission process, explosive may be attached to the distribution device and the material channel device, and the final dosage of the explosive in the medicine box is not easy to control; for example, the last explosive is attached to the distribution device and the material channel device. In order to ensure that the medicine box contains a preset dosage of explosive, the unloading mechanism will inevitably add more explosive, and its dosage is the dosage attached to the distribution device and the material channel device plus the dosage in the medicine box; however, if the next time, the material is still unloaded according to the attached dosage plus the dosage in the medicine box, or the preset dosage in the medicine box is unloaded, it is possible that the attached dosage will be substituted into the medicine box, and there will be a feeding error.

[0004] Therefore, there is an urgent need to propose an explosive weighing device with simple structure, accuracy and reliability. Utility Model Content

An explosion-proof cover lower base plate 21 is arranged at the bottom of the explosion-proof cover 2, and the flipping and pouring mechanism 3 and the vibration feeding mechanism 4 are fixed on the explosion-proof cover lower base plate 21.

[0029] In this embodiment, the overturning and unloading mechanism 3 includes a first lower mounting seat 31 fixed on the workbench 1, an overturning support frame 32 fixed on the first lower mounting seat 31, an overturning plate 33 rotatably arranged on the overturning support frame 32, a clamping cylinder assembly 39 arranged on the overturning plate 33, a charge cartridge 34 clamped on the clamping cylinder assembly 39, an overturning driving mechanism arranged between the overturning plate 33 and the first lower mounting seat 31, and a piston reciprocating vibrator 38 arranged on the back of the overturning plate 33.

In this embodiment, the piston reciprocating vibrator 38 is used to shake and unload slowly to provide the accuracy of unloading.

[0030] In this embodiment, the drug cartridge 34 is clamped on the cylinder assembly 39, which includes a fixed clamping head 391 and a clamping cylinder 392 fixed on the flip plate 33, and a movable clamping head 393 connected to the clamping cylinder 392. The fixed clamping head 391 and the movable clamping head 393 are clamped on the drug cartridge 34.

[0031] In addition, the vibrating feeding mechanism 4 of this embodiment includes a second lower mounting seat 41 fixed on the workbench 1, a column 42 arranged on the second lower mounting seat 41, a first upper mounting seat 43 arranged on the column 42, a first vibrator 44 and a double vibrating unloading mechanism 46 arranged on the first upper mounting seat 43, and a funnel 45 arranged on the first vibrator 44 and receiving the unloading of the drug cartridge 34. Among them, the outlet of the double vibrating unloading mechanism 46 is set through the explosion-proof cover 2 and is placed above the medicine cup 6. Among them, the funnel 45 ensures reliable material reception, and it is connected to the first vibrator 44 to improve the reliability of material transmission.

[0032] In this embodiment, the dual vibration unloading mechanism 46 includes a first ultrasonic micro vibrator 461 and a second ultrasonic micro vibrator 465 arranged on the first upper mounting seat 43, a first straight vibration cover plate 462 arranged on the first ultrasonic micro vibrator 461, a first straight vibration groove 463 connected to the first straight vibration cover plate 462 and placed at the bottom of the funnel 45, a slender mouth 464 arranged at the front end of the first straight vibration groove 463, a second straight vibration cover plate 466 arranged on the second ultrasonic micro vibrator 465, and a second straight vibration groove 467 arranged on the second straight vibration cover plate 466 and placed at the lower part of the first straight vibration groove 463 and the slender mouth 464. In this embodiment, the first ultrasonic micro vibrator 461 drives the first straight vibration groove 463 and the slender mouth 464 to vibrate and transmit the material uniformly. In addition, the second ultrasonic micro vibrator 465 of this embodiment drives the second straight vibration groove 467 to vibrate and further improve the reliability of vibration transmission.

[0033] In this embodiment, the weighing mechanism 5 comprises a third mounting seat 51 fixed on the workbench 1 and a weighing sensor 52 arranged on the third mounting seat 51. The medicine cup 6 is placed on the weighing sensor 52.

[0034] This embodiment can realize rapid feeding and accurate weighing of explosive agent. In addition, it can also achieve good results for agents with poor fluidity. In this embodiment, the funnel 45 and two straight vibration grooves (first straight vibration groove 463, second straight vibration groove 467) of the explosive agent weighing device are respectively connected with respective ultrasonic micro vibrators (first ultrasonic micro vibrator 461, second ultrasonic micro vibrator 465). In this embodiment, there are two working states during feeding: fine feeding and coarse feeding. During the rough feeding, firstly, the funnel 45 supplies appropriate medicine to the upper vertical vibration groove (i.e., the first vertical vibration groove 463); after the medicine in the funnel 45 falls into the first vertical vibration groove 463; the first vertical vibration groove 463 and the second vertical vibration groove 467 work simultaneously through their respective ultrasonic micro-vibrators, and after a certain period of vibration, part of the medicine in the first vertical vibration groove 463 falls into the second vertical vibration groove 467, and the medicine in the first vertical vibration groove 463 and the second vertical vibration groove 467 moves quickly to the outlet end until it falls into the medicine cup on the weighing device. When the weighed medicine reaches the set rough weighing weight, the second vertical vibration groove 467 stops working. The fine feeding continues from the first vertical vibration groove 463. During fine feeding, the second straight vibration groove 467 does not vibrate, so the medicine falling into the second straight vibration groove 467 will stay in place, and only the slender mouth 464 of the first straight vibration groove 463 is feeding. Since part of the medicine falls into the second straight vibration groove, part of the medicine is discharged toward the outlet, and during fine feeding, the vibration amplitude is reduced according to the existing mature PID control to achieve high-precision feeding.

[0035] The above embodiments are only preferred embodiments of the present utility model and are not intended to limit the protection scope of the present utility model. Any changes that adopt the design principles of the present utility model and are made through non-creative labor on this basis should fall within the protection scope of the present utility model.
