Description

Technical Field

[0001] The utility model relates to the technical field of packaging machines, in particular to a double feeding bin structure. Background Art

[0002] Existing solid bulk or granular silos usually have only one discharge port. If two discharge ports are required, a three-way bifurcation is required on the discharge pipeline, which often requires a sufficiently large installation space at the bottom of the silo, or a circular discharge port is used, and two silos are coaxially arranged in the circular discharge port. However, the circular silo cannot quickly close the baffle when sealing the material. After the feeding is stopped, the excess material on the baffle will fall down, which will cause inaccurate weighing of the material to be weighed. Utility Model Content

[0003] The purpose of the utility model is to provide a double feeding silo structure to solve the defects mentioned in the above background technology.

[0004] To achieve the above-mentioned purpose, a double-feeding silo structure is provided, comprising: a silo, a closing door, a coarse feeding port, a fine feeding port, a coarse feeding port rocker and a fine feeding port rocker, characterized in that: the closing door is arranged at the bottom of the silo, the closing door is a square structure, the bottom of the closing door is an open structure, the coarse feeding port and the fine feeding port are arranged in the same row in the closing door, and the fine feeding port rocker and the coarse feeding port rocker are arranged on the side of the closing door;

[0007] Furthermore, the coarse material discharge port rotating shaft and the fine material discharge port rotating shaft are coaxially arranged.

[0008] Furthermore, the rocker handle for the fine material discharge port and the rocker handle for the coarse material discharge port are arranged on the same side and coaxially.

[0009] Furthermore, the number of the dial baffles at the fine material discharge port is greater than the number of the dial baffles at the rough material discharge port.

[0010] Furthermore, the front and rear sides of the material closing door shell are both arc-shaped structures.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. Two feeding ports are set, one for fine feeding and one for rough feeding, so as to control the weight of the material;

DETAILED DESCRIPTION

[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] See also Figure 1The utility model provides a double feeding silo 1 structure, including: a silo 1, a closing door 2, a coarse feeding port 3, a fine feeding port 4, a coarse feeding port rocker 5 and a fine feeding port rocker 6. The closing door 2 is arranged at the bottom of the silo 1. The closing door 2 is a square structure. The bottom of the closing door 2 is an open structure. The coarse feeding port 3 and the fine feeding port 4 are arranged in the same row in the closing door 2. The coarse feeding port 3 is arranged on the left side of the fine feeding port 4. The two feeding ports work separately to prevent one port from dropping the material into the other feeding port during feeding. The fine feeding port rocker 6 and the coarse feeding port rocker 5 are arranged on the side of the closing door 2. The fine feeding port rocker 6 and the coarse feeding port rocker 5 are arranged on the same side and coaxially. The two rockers are arranged on the same side. When in use, the staff only needs to change the rocker without moving, which saves time and effort.

[0021] like Figure 2-Figure 4 As shown, the material closing door 2 includes: an upper material closing door interface 21, a material closing door shell 22 and a lower material closing door interface 23. The upper material closing door interface 21 is fixedly connected to the silo 1, the material closing door shell 22 is fixedly connected to the upper material closing door interface 21, and the lower material closing door interface 23 is fixedly connected to the material closing door shell 22. The coarse material discharge port 3 and the fine material discharge port 4 are separated by the material closing door shell 22. The front and rear sides of the material closing door shell 22 are both arc-shaped structures so that the dial baffle can rotate in the material closing door 2.

[0022] The coarse material discharge port 3 includes a coarse material discharge port dial 31 , a coarse material discharge port dial baffle 32 and a coarse material discharge port rotating shaft 33 , and the fine material discharge port 4 includes a fine material discharge port dial 41 , a fine material discharge port dial baffle 42 and a fine material discharge port rotating shaft 43 . One end of the coarse feed port shaft 33 is connected to the closing door shell 22, and the other end is connected to the coarse feed port rocker handle 5. One end of the fine feed port shaft 43 is connected to the closing door shell 22, and the other end is connected to the fine feed port rocker handle 6. The coarse feed port dial 31 is arranged on the outer ring of the coarse feed port shaft 33. The coarse feed port shaft 33 is longer than the fine feed port shaft 43. The fine feed port 4 has a hollow structure. The coarse feed port shaft 33 is arranged inside the fine feed port shaft 43. The coarse feed port shaft 33 and the fine feed port shaft 43 are coaxially arranged, which can save space and save some cost. Two coarse feed port dial baffles 32 are arranged on the coarse feed port dial 31 , the fine feed port dial 41 is arranged on the outer ring of the fine feed port rotating shaft 43 , and 30 fine feed port dial baffles 42 are arranged on the fine feed port dial 41 .

[0023] Working principle: Pour the material into the silo 1, first rotate the coarse material outlet shaft 33, so that the coarse material outlet dial 31 rotates and drives the coarse material outlet dial baffle 32 to rotate in the closing port. The coarse material outlet dial baffle 32 rotates to allow the material to fall. When the material is about to reach the specified weight, the staff will turn the coarse material outlet dial baffle 32 to close with the closing port shell, stop rotating the coarse material outlet shaft 33, and switch to rotate the fine material outlet shaft 43, so that the fine material outlet dial 41 rotates to drive The fine material discharge port dial baffle 42 rotates in the closing port, and the fine material discharge port dial baffle 42 rotates to allow the material body to fall. When the material body reaches the specified weight, the fine material discharge port rotating shaft 43 stops rotating. At this time, two of the fine material discharge port dial baffles 42 are close to the closing port shell to prevent the material from continuing to fall. The remaining material body in part of the fine material discharge port dial baffle 42 falls into the fine material discharge port dial baffle 42 below to prevent it from falling into the material container. This is the entire working process of the double discharge silo 1 structure.

[0024] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
