[0029] The present invention will be described in detail below with reference to the accompanying drawings.

[0030] like Figures 1 to 10 As shown, the explosive charging mechanism includes a base 1, a charging rack 2, a load-bearing plate 3, a movable rack 4, a charge discharging mechanism 5, a charge charging mechanism 6, a capacity adjustment mechanism 7 and a discharge adjustment mechanism 8. In the figure, a logistics rack 101 is installed on the base 1, and a row wheel 102 is symmetrically arranged on the inner side of the logistics rack 101. A plurality of material trays are movably provided on the row wheel 102, and perforated shells are arranged inside the material trays. A transmission belt can also be arranged on the logistics rack 101.

[0031] In this embodiment, the charging rack 2 is symmetrically and vertically arranged on the base 1, and a top plate 201 is horizontally installed on the upper side of the charging rack 2, and a long slot 202 is provided on the top plate 201; the load-bearing plate 3 is installed between the top plates 201 on both sides by screws or bolts, and a plurality of discharge holes 301 are symmetrically provided on the front side of the load-bearing plate 3, and a collecting hopper 302 is provided on the rear side of the load-bearing plate 3. A valve is installed at the bottom of the collecting hopper 302, and the valve can be connected to the pipeline to automatically recycle the medicine. A baffle 303 is arranged around the top of the load-bearing plate 3, and a notch library is provided on the front of the baffle 303. A movable slide rail 304 is provided at the bottom of the load-bearing plate 3, and a movable oil cylinder 305 is provided at the movable slide rail 304; the movable rack 4 is movably installed in the long slot 2 02, and is arranged on the upper side of the load-bearing plate 3.

The mobile frame 4 can move back and forth repeatedly along the long groove 202 under the drive of the moving oil cylinder 305; the drug discharging mechanism 5 includes a discharging hopper 501, a discharging pipe 502, a discharging head 503 and a brush 504. The discharging hopper 501 is installed on the crossbeam 402 of the mobile frame 4, and the discharging head 503 is installed on the fixed beam 403 of the mobile frame 4. The top of the discharging pipe 502 is connected to the bottom of the discharging hopper 501, and the bottom of the discharging pipe 502 is connected to the inside of the discharging head 503. The brush 504 is installed on the fixed beam 403. The brush 504 is used to clean the excess explosive protruding from the discharging hole 301;

[0032] Specifically, a clearance of 0.2 to 1.0 cm is provided between the bottom of the discharge head 503 and the top of the bearing plate 3. This proper clearance allows for automatic material accumulation and blocking. When the discharge head 503 is not swinging, the bottom will automatically accumulate and block the material, preventing the complete release of the material from the discharge hopper 501. The clearance between the bottom of the discharge brush 504 and the top of the bearing plate 3 is 0 to 0.05 cm, and the lower edge of the discharge brush 504 should be flush with the top of the bearing plate 3 to ensure that the discharge hole 301 is filled with material to the appropriate height.

[0033] In actual use, the front side of the load-bearing plate is equipped with multiple discharge holes to meet the needs of multiple workstations, allowing the discharge of 4 to 6 perforating charges at a time. A collection hopper is located on the rear side of the load-bearing plate to collect excess charge pushed in by the brush. Driven by a hydraulic cylinder, the mobile frame can move back and forth repeatedly, which not only discharges charge from the hopper but also scrapes charge from the brush. This movement pushes any protrusions or accumulated charge beyond the upper edge of the discharge hole into the collection hopper at the rear, ensuring a consistent volume within the discharge hole.

A contact slope is provided on the side of the driving valve 604 close to the metering valve 603. The shape and angle of the contact slope are consistent with the sealing slope.

[0036] It should be noted that the capacity adjustment mechanism can adjust the height of the charging mechanism.

When the capacity adjustment mechanism drives the feeding tube to move upward and the top of the feeding tube does not exceed the top of the discharge hole, the internal volumes of the feeding tube and the discharge hole coincide, resulting in a decrease in the volume of the explosives; when the capacity adjustment mechanism drives the feeding tube to move downward and the top of the feeding tube is not lower than the bottom of the discharge hole, the sum of the internal volumes of the feeding tube and the discharge hole increases, resulting in an increase in the amount of explosives.

[0037] In the figure, the discharge adjustment mechanism 8 is installed at the bottom of the charging mechanism 6 and is used to change the height of the discharge head 801 in the discharge adjustment mechanism 8 to accommodate material trays of different heights. Specifically, the discharge adjustment mechanism 8 includes a discharge head 801, an adjustment slider 802, an adjustment slide 803, an adjustment cylinder 804, and a load-bearing beam 805.
