Description

Technical Field

[0001] The utility model relates to the technical field of unloading equipment, in particular to a ton bag unloading device with a bag breaker. Background Art

[0002] Some raw materials used in the production of compound fertilizers in fertilizer plants, such as phosphate rock powder and potassium salt, are packaged and transported in ton bags. These raw materials need to be unloaded before entering the silo or production equipment. At present, the unloading method of ton bags is to lift the ton bags above the unloading location with a crane or forklift, and the unloading workers cut the bottom of the ton bags with a knife to unload the materials. This unloading method is very unsafe, and sometimes the raw materials poured from the ton bags will pour on the unloading workers. In addition, some ton bags will be stored for too long, and the slings of the ton bags will age and lack strength. During the process of lifting and unloading with a crane or forklift, the slings will suddenly break and the ton bags will fall. At this time, the unloading workers at the bottom of the ton bags are in danger of being crushed. At the same time, since the unloading workers are directly next to the ton bags, dust will fly during the unloading process, and the unloading workers can easily inhale it, which will also affect their health.

[0003] Therefore, in the process of unloading ton bags in fertilizer plants, it is urgent to improve the unloading tools for ton bags. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide a ton bag unloading device with a bag breaker to address the deficiencies of the prior art. The ton bag can be lifted to the top of the unloading device by a crane or a forklift, and then dropped to break the bag for unloading. The whole process does not require operators to cut the bag under the ton bag, and the safety is high and the unloading efficiency is also high.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A ton bag unloading device with a bag breaker, comprising a unloading hopper, wherein the bag breaker is arranged in the unloading hopper, wherein the bag breaker comprises a fixing frame and a bag breaker knife, wherein the bag breaker knife is a cone-shaped structure, and has 3-8 knife bodies facing outwards, each of the knife bodies is provided with a serrated blade facing upwards, and all the knife bodies have a common knife tip at the top of the cone, and the bag breaker knife is fixedly arranged on a fixing frame, and the fixing frame is arranged on the upper part of the unloading hopper;

[0007] The lower part of the discharge hopper is provided with a discharge port, and a belt conveyor is arranged below the discharge port.

[0008] Furthermore, the tip of the bag breaking knife is higher than the upper edge of the discharge hopper.

[0009] Furthermore, the circumference of the blade body of the bag breaking blade is evenly arranged.

[0010] Furthermore, the blade body of the bag breaking knife is similar to a right triangle, the hypotenuse is a serrated blade, and the long right-angled sides are welded and fixed to each other.

[0011] Furthermore, the blade body of the bag breaking knife is similar to a trapezoid, the lower bottom is a serrated blade, and the waist is welded and fixed to each other to form a blade tip.

[0012] Furthermore, the fixing frame includes a cross-shaped frame and a circular frame, the circular frame is arranged in the cross-shaped frame, with the intersection of the cross-shaped frame as the center of the circle, the bag breaking knife is fixedly arranged on the circular frame, and the orthographic projection of the tip of the bag breaking knife is located at the intersection of the cross-shaped frame.

[0013] Furthermore, a grid plate is also provided on the fixing frame.

[0014] Furthermore, a vibrator is provided on the discharge hopper for vibrating the discharge material.

[0015] The utility model discloses a ton bag unloading device with a bag breaker. When unloading, the ton bag is lifted to the top of the hopper by a crane or a forklift and then lowered. The ton bag contacts the bag breaker. Under the action of the gravity of the ton bag, the bag breaker cuts the bottom of the ton bag, and the raw materials in the ton bag flow out of the broken hole to realize unloading.

[0016] The beneficial effects of the utility model are:

[0017] 1. The utility model provides a ton bag unloading device with a bag breaker, which does not require unloading workers to cut bags manually, thereby improving the safety of the unloading process.

[0018] 2. The utility model provides a ton bag unloading device with a bag breaker. The vibration device can also speed up the flow rate of the raw materials in the ton bag, thereby improving the unloading efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
