Description

Technical Field

[0001] This utility model belongs to the technical field of emulsion explosive dosage measuring instruments, specifically relating to a device for measuring the dosage of emulsion explosives used in production. Background Technology

[0002] Existing emulsion explosive charge measuring instruments require operators to manually handle and place the emulsion explosives. This can easily lead to arm fatigue over long periods of handling. Furthermore, existing rotatable unloading measuring instruments require waiting for the weighing tray to rotate and reset before the next charge can be measured, which is inconvenient for operators. Summary of the Invention

[0003] The purpose of this invention is to allow workers to remove the emulsion explosive from the measuring instrument without using their hands, thus reducing the workload on their arms. Furthermore, it allows for the rapid removal of the measured emulsion explosive from the weighing tray during unloading, and enables the separate collection of qualified and unqualified emulsion explosive. The technical solution is as follows:

Detailed Implementation

[0011] Reference Figures 1-4 The device for measuring the amount of emulsion explosive used in production is characterized by: a fixed base 1 and an anti-slip pad 2 connected to the middle of the lower surface of the fixed base 1; a weighing host 3 connected to the middle of the upper surface of the fixed base 1; connecting columns 4 movably inserted at the four corners of the upper surface of the weighing host 3; a measuring pan 5 connected between the upper surfaces of the four connecting columns 4; a discharge device 6 connected to the middle of the lower surface of the measuring pan 5; and collection trolleys 7 symmetrically arranged above the middle of the left and right side surfaces of the fixed base 1.

[0012] In use, place the fixed base 1 at the front end below the conveyor belt. At the same time, the anti-slip pad 2 increases the friction of the fixed base 1. Then, the operator pushes the collection trolley 7 to contact the side surface of the fixed base 1. Then, start the conveyor belt to transport the emulsion explosive to the front end and drop it onto the measuring weighing pan 5. When the emulsion explosive falls onto the measuring weighing pan 5, stop the conveyor belt rotation. Since the emulsion explosive is placed flat on the conveyor belt, two or more will not fall onto the measuring weighing pan 5. Then, the weight of the emulsion explosive presses down on the measuring weighing pan 5 and simultaneously presses down the connecting column 4 into the weighing host 3. At the same time, the display screen on the weighing host 3 displays the weight. If the weight is qualified, press the qualified button and start the discharge device 6 to push the qualified emulsion explosive to the right end and drop it into the right-side collection trolley 7. If the weight is unqualified, press the unqualified button and start the discharge device 6 to push the unqualified emulsion explosive to the left end and drop it into the left-side collection trolley 7.

[0013] Furthermore, the measuring weighing pan 5 includes a tray 5-1, a through hole 5-2, an inclined plate 5-3, and rolling balls 5-4. The tray 5-1 has a through hole 5-2 in the middle of its lower surface. Inclined plates 5-3 are symmetrically connected to the middle of the lower edges of the left and right sides of the tray 5-1. Several rolling balls 5-4 are evenly distributed and movably inserted into the lower surface of each inclined plate 5-3. The tray 5-1 and the inclined plate 5-3 are U-shaped. The tray 5-1 is connected between the upper surfaces of the four connecting columns 4 at the middle.

[0014] When in use, the conveyor belt stops rotating when the emulsion explosive falls onto the tray 5-1. Then, the emulsion explosive presses down on the tray 5-1 by its own weight, while simultaneously pressing down the connecting column 4 into the weighing host 3. At the same time, the display screen on the weighing host 3 shows the weight. After the measurement is completed, the emulsion explosive is pushed onto the inclined plate 5-3. Since the outer end of the inclined plate 5-3 is inclined downward and the inner lower surface of the inclined plate 5-3 is equipped with a ball 5-4, the emulsion explosive can slide out and fall into the collection trolley 7.

[0015] Furthermore, the discharge device 6 includes a roller 6-1, a rubber sleeve 6-2, a side plate 6-3, and a motor 6-4. The rubber sleeve 6-2 is inserted around the outer surface of the roller 6-1. The side plate 6-3 is symmetrically connected to the center of the front and rear surfaces of the roller 6-1. The motor 6-4 is connected to the middle of the lower outer surface of the rear side plate 6-3. The rotating end of the front end of the motor 6-4 penetrates the side plate 6-3 and is connected to the center of the rear surface of the roller 6-1. The roller 6-1 is inserted through the through hole 5-2. The side plate 6-3 is connected to the lower surface of the tray 5-1.

[0016] When the measured emulsion explosive is qualified, the operator presses the qualified button to start the motor 6-4 so that the rotating end rotates forward. At the same time, the rotating end of the motor 6-4 drives the roller 6-1 to rotate forward in the through hole 5-2. Meanwhile, the rubber sleeve 6-2 contacts the emulsion explosive and increases the friction, causing the roller 6-1 to push the emulsion explosive to the right and push it to the right inclined plate 5-3. Finally, the emulsion explosive is dropped into the right collection trolley 7 through the cooperation of the inclined plate 5-3 and the rolling ball 5-4.

[0017] When the measured emulsion explosive is unqualified, the operator presses the unqualified button to start the motor 6-4, causing the rotating end to reverse. At the same time, the rotating end of the motor 6-4 drives the roller 6-1 to reverse within the through hole 5-2. Simultaneously, the rubber sleeve 6-2 contacts the emulsion explosive and increases the friction, causing the roller 6-1 to push the emulsion explosive to the left and push it to the left inclined plate 5-3. Finally, the emulsion explosive is dropped into the left collection trolley 7 through the cooperation of the inclined plate 5-3 and the rolling ball 5-4.

[0018] Furthermore, the collecting trolley 7 includes a carriage 7-1, rubber pads 7-2, rollers 7-3, and handles 7-4. Rubber pads 7-2 are connected to the four sides and the lower surface of the carriage 7-1. Rollers 7-3 are connected to the four corners of the lower surface of the carriage 7-1. A handle 7-4 is connected to the middle of the upper edge of the right side surface of the carriage 7-1. The left side surface of the carriage 7-1 is in contact with the fixed base 1. The position of the outer end of the inclined plate 5-3 corresponds to the position of the carriage 7-1.

[0019] When in use, the operator holds the handle 7-4 and pushes the carriage 7-1 to the side surface of the fixed base 1 and makes contact. At the same time, the roller 7-3 rolls on the ground to reduce friction. When the emulsion explosive falls into the carriage 7-1, the rubber pad 7-2 inside the carriage 7-1 can cushion the emulsion explosive and prevent it from being damaged when it hits the inner wall of the carriage 7-1.

[0020] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
