Description

Technical Field

[0001] The utility model relates to the technical field of weighing devices, and more specifically to a weighing device which is convenient for loading materials. Background Art

[0002] A weighing device is a device that can measure the weight of an object. After the material production is completed, the batch of materials is often effectively stored in a material box. Before being stored in the material box, each batch of materials must be weighed by a weighing device to obtain its weight data for subsequent retrieval and use.

[0003] At present, in the process of feeding granular and powdery fine materials to the measuring plate in the weighing device, in order to facilitate the taking and discharging of the measuring plate after weighing, the discharge port is often set above the measuring plate in the weighing device, with a certain suspended height between it, so that when the granular and powdery fine materials fall onto the measuring plate, it is easy for some materials to splash outward, and some granular and powdery fine materials are easy to remain on the inner wall of the feeding pipe, so that in the feeding process, some materials remain and do not fall, and some materials fall and splash to the outside, resulting in insufficient and comprehensive material feeding and poor feeding effect. Therefore, it is urgent to improve the technology of the weighing device to improve this equipment.

[0004] Therefore, the utility model provides a weighing device which is convenient for loading materials. Utility Model Content

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

[0024] Example:

[0025] See also Figure 1-3A weighing device for convenient loading includes a base 1, a weighing device 2 is installed on the upper end of the base 1, and a material tray 3 is placed on the upper end of the weighing device 2, a pair of support plates 4 are fixedly connected to the upper end of the base 1, and a conveying cylinder 5 is fixedly connected between the upper ends of the pair of support plates 4, a spiral conveying mechanism 7 is installed on the conveying cylinder 5, a feeding pipe 6 is fixedly connected to the upper end of the conveying cylinder 5, and a discharging pipe 8 is fixedly connected to the lower end of the conveying cylinder 5, a telescopic hose 9 is fixedly connected to the lower end of the discharging pipe 8, and the left and right ends of the telescopic hose 9 are fixedly connected with an arc plate 12, the left and right ends of the discharging pipe 8 are fixedly connected with a connecting plate 10, and an electric telescopic rod 11 is installed between the connecting plate 10 and the arc plate 12, and a knocking mechanism 13 is installed between the pair of connecting plates 10 and the discharging pipe 8.

[0026] During the use of this solution, first, a pair of electric telescopic rods 11 drives the telescopic hose 9 to extend downward by pushing the arc plate 12 and penetrates into the bottom end of the material tray 3. Then, the powder or granular material enters the conveying cylinder 5 through the feed pipe 6. The motor 702 in the spiral conveying mechanism 7 works to drive the rotating rod 701 and the spiral blade 703 to rotate, so as to transport the powder or granular material in an orderly manner. The material enters the discharge pipe 8 after being transported, falls downward into the telescopic hose 9, and is then discharged into the material tray 3. Since the telescopic hose 9 extends into the material tray 3 and no longer has a suspended height, it is not easy for the material to splash outward during the falling process, thereby ensuring the adequacy of material feeding. In addition, a pair of electric telescopic rods 11 drives the telescopic hose 9 to move along with the material tray 3. The accumulated materials in the disk 3 gradually move upward to adjust its height to avoid blockage. At the same time, a pair of telescopic cylinders 1302 in the knocking mechanism 13 work to drive the movable plate 1303 to reciprocate left and right in the horizontal direction, so that it drives the knocking hammer 1304 to reciprocate left and right, respectively contacting the discharge pipe 8 and the straight plate 1301, and knocking and vibrating them, so that the discharge pipe 8 and the straight plate 1301 vibrate and transmit them to the telescopic hose 9, causing the discharge pipe 8 and the telescopic hose 9 to vibrate, driving the powder or granular materials attached to the inner walls of the discharge pipe 8 and the telescopic hose 9 to loosen under the action of vibration, reducing their adhesion so as to make them fall down, reducing the residue of materials, ensuring the full and comprehensive feeding, and further enhancing the feeding effect.
