Description

Technical Field

[0001] The utility model relates to the technical field of rice processing, in particular to a rice processing concentrator. Background Art

[0002] Rice, also known as "paddy", has the functions of nourishing the stomach, improving the essence and strengthening the will, improving hearing and eyesight, harmonizing the five internal organs, promoting blood circulation, relieving restlessness, quenching thirst, and stopping diarrhea. Therefore, rice is very nutritious and is one of the main foods of the Chinese people. Therefore, people's lives cannot be separated from the consumption of rice.

[0003] In order to make rice more edible and improve its quality, the rice needs to be further processed and selected so that the smaller particles in the rice can be separated from the rice. During the rice production and processing, particles smaller than the standard and broken rice need to be sorted out to leave high-quality rice. In the process of selecting rice, the existing rice processing selection machine generally uses a rotating drum machine to select the rice. However, the existing rice processing selection machine may cause the rice to break during the rotation process, thereby causing certain damage to the rice, resulting in less high-quality rice, thereby reducing rice production efficiency. Therefore, the present application proposes a rice processing selection machine to solve the above problems. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-Figure 5 A rice processing concentrator includes an installation box 1, and a lower hopper 14 for unloading is fixedly installed on the upper end of the installation box 1. The lower hopper 14 is an open hopper structure with a larger upper part and a smaller lower part, which facilitates the falling of rice so that the rice can fall onto the filter screen 13.

[0023] Two longitudinally arranged material guide partitions 2 and two transversely arranged support plates 3 are installed in the installation box 1. The material guide partitions 2 are fixed to the bottom of the installation box 1 cavity, and the support plates 3 are fixed to the inner side ends of the installation box 1 cavity. The material guide partitions 2 play a role in separating the screened rice to avoid mixing of the screened rice and the isolated rice. A filter element 4 for rice screening is tilted between the material guide partitions 2 and the support plates 3. The filter element 4 is hinged to the material guide partitions 2. A telescopic spring 5 for driving the filter element 4 is installed on the support plate 3. Under the action of the telescopic spring 5, the support plate 3 can support one end of the filter element 4 to facilitate the installation of the filter element 4. A rotating motor 6 is fixedly installed on the outside of the installation box 1 through a motor frame. The output end of the rotating motor 6 is synchronously installed with a rotating shaft 7 that rotates in the installation box 1. A rotating cam 8 that drives the filter element 4 is synchronously installed on the rotating shaft 7. The rotating cam 8 and the filter element 4 always slide against each other. It should be noted that the rotating motor 6 is an existing motor that can drive the rotating cam 8 to rotate through the rotating shaft 7;

[0024] The filter element 4 includes a filter frame 11 between the telescopic spring 5 and the material guide partition 2. A filter net 13 for rice screening is fixedly installed on the filter frame 11 by screws 12. Under the action of the telescopic spring 5, the filter frame 11 can be pushed so that the filter frame 11 can always slide against the rotating cam 8.

[0025] By connecting the filter screen 13 to the filter frame 11 with screws 12 , the filter screen 13 can be easily replaced and disassembled.

[0026] The filter frame 11 is a square structure, and the side ends of the filter frame 11 slide against the side walls of the installation box 1 to prevent the filtered rice from sliding off the side ends of the installation box 1 .

[0027] A collecting box 9 for collecting smaller particles after filtration is provided in the installation box 1 and at the lower end of the filter element 4. An opening slot 15 is provided at the side end of the installation box 1 for facilitating the removal of the collecting box 9, making it convenient to take out the collecting box 9 and to take out the smaller particles filtered out of the collecting box 9. A drop-out port 10 is provided at the bottom of the installation box 1. The drop-out port 10 is located between the two material guide partitions 2. The drop-out port 10 is a frustum structure with a larger upper portion and a smaller lower portion, which is convenient for the filtered rice to fall. A collecting piece 19 is provided at the lower end of the installation box 1 through an installation tube 18 and communicates with the drop-out port 10. It should be noted that the collecting piece 19 is an existing device, and a collecting bag can be preferably selected to collect the filtered rice.

[0028] An installation groove 16 is provided on the other side of the installation box 1, and a switch door 17 is movably installed in the installation groove 16, which not only facilitates the installation and replacement of mechanical parts in the installation box 1, but also facilitates the heat dissipation of the installation box 1 to prevent the inside of the installation box 1 from overheating when the equipment is working. It should be noted that the installation method between the switch and the installation groove 16 is a prior art and will not be elaborated here.

[0029] The utility model can explain its functional principle through the following operation methods:

[0030] During operation, the rotating shaft 7 is first driven by the rotating motor 6 to rotate, so that the rotating cam 8 rotates synchronously with the rotating shaft 7, and the rotating cam 8 drives the filter element 4 as a whole. Under the pushing action of the telescopic spring 5, the filter element 4 can swing along with the rotating cam 8 with the intersection between the filter element 4 and the material guide partition 2 as the fulcrum, so that one end of the filter element 4 fluctuates up and down, thereby filtering the rice falling from the lower hopper 14. The filtered selected rice falls with the filter element 4 between the two material guide partitions 2 and is collected by the collecting element 19 through the drop port 10 and the mounting pipe 18;

[0031] The smaller rice particles are filtered by the filter element 4 and fall into the collection box 9, and the collection box 9 can be cleaned regularly.

[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
