[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example 1

[0021] See also Figure 1-3A novel material shortage alarm device for a loading bin comprises a spiral feeder 1 and a base 2. A support leg 3 is fixed to the lower surface of the material bin of the spiral feeder 1. The support leg 3 is arranged at four corners of the material bin of the spiral feeder 1. A support seat 4 is fixed to the lower end surface of the support leg 3. A compression spring 5 is fixed to the lower end surface of the support leg 3. The compression spring 5 is fixed to the surface of the base 2. A positioning rod 6 is fixed to the upper surface of the base 2. A support rod 7 is fixed to one side of the base 2. A support plate 8 is fixed to the surface of the support rod 7. A travel switch 9 and an audible and visual alarm 10 are fixed to the surface of the support plate 8. A support platform 11 is fixed to the side of the material bin of the spiral feeder 1. A lifting top plate 12 is arranged on the upper end of the support platform 11. Bolts 13 are connected to the inner surface of the support platform 11 through threads.

[0022] A positioning rod 14 is fixed to the lower surface of the lifting top plate 12, and the positioning rod 14 is inserted into the inner surface of the support platform 11. The positioning rod 14 adopts a round rod structure. Two groups of positioning rods 14 are distributed and fixed on the lower surface of the lifting top plate 12. The surface of the support seat 4 is provided with an insertion hole, and the positioning rod 6 is inserted into the inner surface of the insertion hole of the support seat 4, so as to facilitate the positioning and up and down movement of the lifting top plate 12;

[0023] The lifting top plate 12 is arranged in a distributed manner to align with the travel switch 9, and the travel switch 9 is connected to the sound and light alarm 10 and the power supply circuit through a series circuit;

[0024] When in use, the position of the lifting top plate 12 is adjusted by twisting the bolt 13 up and down to ensure that it can be squeezed at the travel switch 9 when the warehouse is empty, and the travel switch 9 is ensured to be turned on. At this time, the silo is filled with materials, and the weight of the materials compresses the silo to descend, and the compression spring 5 descends, so that the support seat 4 can slide on the surface of the positioning rod 6 for positioning support. The weight of the silo becomes lighter during loading, and the silo rebounds and rises through the compression spring 5. When there is a lack of materials, the travel switch 9 can be squeezed, and the sound and light alarm 10 can be turned on to turn on the alarm to remind the staff of the lack of materials. It can remind the staff at the first time, which is convenient to use.

[0025] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
