Description

Technical Field

[0001] This utility model relates to the field of feeding machinery technology, and in particular to a bag-breaking device with a riveting cone. Background Technology

[0002] In industrial production processes, electric belt conveyors are widely used for raw material pretreatment, transportation, and feeding. Dust is stirred up by the high-speed movement of the belts and is difficult to settle in the flow field, polluting not only the workplace environment but also endangering the health of workers. In addition, raw materials that are loosely packed for a long time also suffer from problems such as deliquescence, charging, and component segregation leading to changes in properties.

[0003] To avoid dust generated by belt conveyors and performance changes caused by loose packing, industrial raw materials are generally bagged and stored in warehouses. During production, a bridge crane or belt is used to transport the bagged raw materials to the bag breaker, where gravity breaks the bags, and the materials then enter the raw material silo directly.

[0004] However, in the actual process of bag breaking and feeding, the piercing cone will wear down after long-term use, making it unable to pierce the packaging bag, affecting work efficiency and causing problems such as material jamming; at the same time, the support will also suffer fatigue failure under alternating stress, posing a risk of breakage; the existing technology usually welds the piercing cone and the support into the bag breaker as a whole, which makes replacement very difficult; if the piercing cone and the support are connected by threads, under long-term chemical corrosion and physical impact, the threads are at risk of rusting and deformation, making disassembly impossible. Therefore, improvements need to be made to the existing technology. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Reference Figures 1-6 This utility model discloses a bag-breaking device with a riveted cone, including a body 1 for feeding, a bag-breaking component for breaking bags is provided in the feeding port on the top surface of the body 1, and a raw material silo 4 for storing materials is fixedly connected and communicated with the discharge port on the bottom surface of the body 1; the bag-breaking component includes a cone 2, one end of the cone 2 extending into the body 1 is detachably connected to a bracket 3 by a number of rivets, the bracket 3 is set inside the body 1, the height of the apex of the cone 2 is higher than the height of the top surface of the body 1, and the central axis of the cone 2 is on the same central axis as the central axis of the body 1.

[0029] The bracket 3 is made of stainless steel, and the awl 2 is made of manganese silicon steel.

[0030] The stainless steel bracket 3 is corrosion resistant, while the silicon manganese steel awl 2 has high hardness, good toughness, and is resistant to impact loads. It can be used for a long time and has good riveting performance.

[0031] This utility model uses rivets to install the awl 2 on the bracket, which allows for the replacement of the severely worn awl 2 at any time via hot melting. The awl 2 and the bracket 3 are riveted together, which not only reduces the number of parts and facilitates replacement, but also ensures high installation accuracy and fixing strength.

[0032] The blade cone 2 consists of two double-edged blades with overlapping spines. The blades are positioned with the cutting edges facing upwards and extending beyond the top surface of the machine body 1 to meet the requirements for breaking bags.

[0033] Further optimizing the design, the bracket 3 includes several connecting rods, with the central axes of the opposite ends of these connecting rods pointing towards the same center. Each of the opposite ends of the connecting rods has a positioning groove 32, which is detachably connected to the cone 2. The opposite ends of the connecting rods are fixedly connected to the inner wall of the machine body 1. In other words, the connecting rods are fixedly connected to the corner of the machine body 1, and the bracket 3 is fixed by the beveled surface of the corner, exhibiting good impact resistance and capable of withstanding large impact loads.

[0034] To further optimize the design, rivet holes 31 for placing rivets are respectively provided on the positioning groove 32 and the cutting cone 2. This allows the cutting cone 2 to be installed in the positioning groove 32 by rivets.

[0035] In a further optimized design, a countersunk rivet hole 24 is provided at the end of the positioning groove 32 away from the cone 2, where the rivet hole 31 is located.

[0036] The design is further optimized so that the rivet includes a rivet shank 22, one end of which is fixedly connected to a rivet head 21, and the other end of which is fixedly connected to an upsetting head 23.

[0037] The design was further optimized so that the nail head 21, nail rod 22, and upsetting head 23 are integrally formed.

[0038] The design is further optimized so that the upsetting head 23 and the countersunk riveting hole 24 are detachably connected and compatible. The upsetting head 23 and the countersunk riveting hole 24 are conical in shape, so that the upsetting head 23 can be stably positioned within the countersunk riveting hole 24.

[0039] In a further optimized design, the nail head 21 is detachably connected to the end of the awl 2 furthest from the bracket 3. The diameter of the nail head 21 is larger than the diameter of the rivet hole 31, allowing the nail head 21 to stably fix the awl 2 onto the bracket 3.

[0040] The awl 2 is installed on the bracket 3 by riveting. The riveting installation of the awl 2 reduces the number of parts, improves installation accuracy and fixing strength, and the rivets can be easily removed by hot melting or grinding.

[0041] To further optimize the design, a bin vibrator 11 is installed on the outer wall of the machine body 1 to vibrate the machine body 1. The vibration of the bin vibrator 11 effectively prevents material blockage caused by internal friction, deliquescence, electrical charge, or component segregation.

[0042] To further optimize the design, a radar level gauge 41 is installed on the outer wall of the raw material silo 4. The radar level gauge 41 enables animated material discharge.

[0043] This utility model uses riveting to fix the blade cone 2 on the bracket 3, which not only effectively reduces the number of parts, but also facilitates the replacement of the blade cone 2; at the same time, it can also improve the operational stability of the equipment and effectively improve the bag breaking efficiency.
