Description

Technical Field

[0001] The utility model relates to the technical field of machinery, in particular to a transmission mechanism for explosives. Background Art

[0002] Explosive agents are highly sensitive to friction and impact, and many of them can supply oxygen by themselves. In case of strong friction and impact, they are prone to combustion or even explosion accidents, and it is difficult to crush them directly. The commonly used crushing method in the pyrotechnic industry is water crushing, and the crushing equipment used is claw-type crushing equipment. During crushing, a large amount of heat will be generated when the claws rub, collide and shear with the explosive column or particles. To ensure safety, the pyrotechnic agent to be refined will be soaked in water, and the feeding requires good stability to prevent excessive materials from overloading the equipment and causing overheating, combustion and explosion.

[0003] However, materials with high water content have great viscosity and poor fluidity. When using an ordinary feeding funnel to add materials, the materials will adhere to the inner wall of the funnel, and even form a cavity after the materials below are drained out, and the materials above cannot collapse by their own weight, resulting in material breakage. The current feeding method is the original funnel feeding, which requires operators to observe and manually turn the materials at all times. This feeding method is greatly affected by human factors, the feeding is unstable, and the operator needs to operate at close range. It is impossible to achieve human-machine isolation, and the inherent safety cannot be guaranteed during production. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a pyrotechnic agent conveying mechanism to solve the problem in the prior art that a cavity is formed at the lower part of the hopper and the pyrotechnic agent material above cannot collapse by its own weight, thus causing material breakage.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] The transmission mechanism of the explosive agent comprises:

[0007] frame;

[0008] A conveyor belt body, the conveyor belt body is connected to the frame, the conveyor belt body comprises a lifting and conveying section, and scraper strips are arranged on the belt surface of the conveyor belt body at equal intervals, and the scraper strips are perpendicular to the conveying direction of the conveyor belt body;

[0009] A material storage bucket, the material storage bucket is connected to the frame, the material storage bucket is located above the lifting and conveying section of the conveyor belt body, the horizontal cross-section of the material storage bucket is rectangular, and the material storage bucket includes two side plates located on both sides of the conveyor belt body, and the inner wall of the side plate is provided with a limit sleeve;

[0010] Movable rods, wherein two movable rods are respectively slidably connected in two limit sleeves;

[0011] A shaft rod, the shaft rod being connected between the lower ends of the two movable rods;

[0012] A disc material turner is arranged in the material storage bucket, the disc material turner is rotatably connected to the shaft rod, and the circumferential surface of the disc material turner is distributed with multiple ribs in a circular array, and the ribs are perpendicular to the conveying direction of the conveyor belt body.

[0013] Furthermore, in the above-mentioned pyrotechnic agent conveying mechanism, the ratio of the distance between two adjacent convex ribs to the distance between two adjacent scraping strips is 1:3-5.

[0014] Furthermore, in the above-mentioned pyrotechnic agent conveying mechanism, the height of the scraper strip is 4-6 mm.

[0015] Furthermore, in the above-mentioned pyrotechnic agent conveying mechanism, the ratio of the diameter of the disc material turner to the front-to-back width of the material storage bucket is 1:1.5-2.

[0016] Furthermore, in the above-mentioned pyrotechnic agent conveying mechanism, a counterweight is connected to the upper end of the movable rod.

[0017] Furthermore, in the above-mentioned pyrotechnic agent conveying mechanism, the angle between the belt surface of the lifting section of the conveyor belt body and the horizontal plane is 40-50 degrees.

[0018] Furthermore, in the above-mentioned pyrotechnic agent transmission mechanism, the angle between the axial direction of the movable rod and the horizontal plane is 75-80 degrees.

[0019] The beneficial effects of the utility model are as follows: through the cleverly designed disc turner and its freely liftable connection relationship, two functions are achieved without the need for an additional power source. One is to crush the agglomerated materials; the other is to automatically turn the materials when there is a cavity under the material storage bucket by intermittently rotating under the transmission of the scraper strip of the conveyor belt body, so that the materials collapse and fall into the cavity, thereby ensuring continuous transportation of the materials.

[0029] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0030] Please refer to Figure 1 as well as Figure 2 The specific implementation of the utility model relates to a transmission mechanism for explosives, including:

[0031] Rack 1;

[0032] A conveyor belt body 2, the conveyor belt body 2 is connected to the frame 1, the conveyor belt body 2 comprises a lifting and conveying section 21, and scraper strips 22 are arranged on the belt surface of the conveyor belt body 2 at equal intervals, and the scraper strips 22 are perpendicular to the conveying direction of the conveyor belt body 2;

[0033] A material storage bucket 3, the material storage bucket 3 is connected to the frame 1, the material storage bucket 3 is located above the lifting and conveying section 21 of the conveyor belt body 2, the horizontal cross-section of the material storage bucket 3 is rectangular, and the material storage bucket 3 includes two side plates located on both sides of the conveyor belt body 2, and the inner wall of the side plate is provided with a limit sleeve 31;

[0034] Movable rods, two movable rods are respectively slidably connected in two limiting sleeves 31;

[0035] A shaft rod 4, wherein the shaft rod 4 is connected between the lower ends of the two movable rods;

[0036] The disc turner 5 is arranged in the material storage bucket 3, and the disc turner 5 is rotatably connected to the shaft rod 4. The circumferential surface of the disc turner 5 is distributed with multiple ribs 51 in a circular array, and the ribs 51 are perpendicular to the conveying direction of the conveyor belt body 2.

[0037] In the above embodiments, the conveyor belt body 2 is connected to an explosion-proof variable frequency motor 23, and the conveyor belt body 2 is driven by the explosion-proof variable frequency motor 23 to continuously rotate.

[0038] In the above embodiments, the belt surface of the conveyor belt body 2 is a corrosion-resistant flexible belt; the width of the conveyor belt body 2 is 50 mm.

[0039] Working principle: In the initial state, the disc tipper 5 is held against the belt surface of the conveyor belt body 2 by its gravity or external force, and the semi-wet pyrotechnic agent to be crushed is manually added to the material storage bucket 3 (when the volume of the material storage bucket 3 is 20 liters, 15 kg of pyrotechnic agent with water can be stored in the material storage bucket 3). The explosion-proof variable frequency motor 23 is turned on to drive the conveyor belt body 2 to rotate continuously, and the pyrotechnic agent in the material storage bucket 3 is continuously scraped and sent through the scraper strip 22 on the surface of the conveyor belt body 2. At this time, the disc tipper 5 is lifted up by the pushed material, which plays a certain role in auxiliary feeding, that is, when the scraper strip 22 drives the material to pass under the disc tipper 5, the disc tipper 5 is used to scrape the material. The circumferential surface of the disc turner 5 squeezes the scraper strip 22 to push the material, and uses the convex ribs 51 on its surface to crush the agglomerated pyrotechnic agent, so that it can be smoothly sent out of the material storage bucket 3; when the material at the bottom of the material storage bucket 3 is scraped off, a cavity is formed due to the extremely high viscosity of the material itself, and the disc turner 5 sinks under the action of gravity and contacts the surface of the conveyor belt again. The extended convex ribs 51 and the scraper cause the disc turner 5 to rotate intermittently under the push of the scraper strip 22, so that the other convex ribs 51 of the disc turner 5 play the role of turning over the pyrotechnic agent in the material storage bucket 3, so that the pyrotechnic agent collapses under the action of gravity after being turned over until it contacts the conveyor belt body 2, so that the pyrotechnic agent can be continuously scraped out.

[0040] As a preferred embodiment, the ratio of the distance between two adjacent convex ribs 51 to the distance between two adjacent scraper strips 22 is 1:3-5.

[0041] Preferably, the distance between two adjacent scraper strips 22 is 50 mm, and the distance between two adjacent convex ribs 51 is 15 mm.

[0042] As a preferred embodiment, the scraper strip 22 has a height of 4-6 mm. Preferably, the scraper strip 22 has a width of 50 mm and a height of 5 mm.

[0043] As a preferred embodiment, the ratio of the diameter of the disc material turner 5 to the front-to-back width of the material storage bucket 3 is 1:1.5-2.

[0044] The above width ratio can further ensure the continuous feeding of the pyrotechnic agent material. If the front-to-rear width of the material storage bucket 3 is too large, the material turning effect will be affected. If the width is too small, the volume of the material storage bucket 3 will be affected.

[0045] As a preferred embodiment, a counterweight 6 is connected to the upper end of the movable rod.

[0046] In the above embodiments, the counterweight 6 is preferably a counterweight ball, which serves to increase the weight of the disc turner 5 .

[0047] As a preferred embodiment, the angle between the belt surface of the lifting section of the conveyor belt body 2 and the horizontal plane is 40-50 degrees.

[0048] As a preferred implementation, the angle between the axis of the movable rod and the horizontal plane is 75-80 degrees.

[0049] In the above embodiment, the axial direction of the movable rod is the direction in which the disc turner 5 moves up and down, and this angle is very critical. If the angle is completely vertical, the resistance will be too large during the pushing process of the material, making it difficult to lift the disc turner 5, so that the material pushed by the scraper strip 22 is easily squeezed out by the disc turner 5, affecting the feeding efficiency. If the angle between the axial direction of the movable rod and the horizontal plane is too small, the component force of the disc turner 5 pressing against the belt surface of the conveyor belt body 2 will be too small, resulting in the convex rib 51 of the disc turner 5 being unable to fully contact with the scraper strip 22 and the transmission being unstable, thereby affecting the turning efficiency.

Any equivalent transformations made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in the relevant technical field, are also included in the patent protection scope of the present invention.
