Description

Technical Field

[0001] This utility model relates to a rice storage bin, specifically a rice storage bin for reducing the broken rice rate of Wuchang rice. Background Technology

[0002] Rice is obtained by hulling paddy. Paddy grains consist of the husk, bran, germ, and endosperm. The purpose of paddy processing is to separate the endosperm from the other parts with minimal breakage, producing rice with better eating quality. After processing, the rice is stored in a rice storage silo. The silo includes a support frame and a vertically arranged cylindrical silo mounted on the support frame. A funnel-shaped discharge hopper is fixedly connected to the bottom of the silo, and an inlet is located at the top. When rice is stored in the silo, it flows directly into the silo through the inlet. The rice falls quickly and may break upon reaching the bottom of the silo.

[0003] Wuchang rice, produced in Wuchang City, Heilongjiang Province, is a type of rice that is very popular among consumers due to the special geographical environment in Wuchang. However, Wuchang rice is easily broken due to its special grain shape and structure. If it is stored in the above-mentioned grain silos, the rice will flow directly into the silos through the rice inlet. The rice falls quickly and is easily broken when it reaches the bottom of the silos, which leads to a decrease in the polished rice rate and reduces the economic benefits of the factory. Summary of the Invention

[0004] The purpose of this invention is to provide a rice storage bin that reduces the broken rice rate of Wuchang rice. This rice storage bin is used to solve the problem of broken rice caused by existing rice storage bins during the storage of Wuchang rice.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: This rice storage bin for reducing the broken rice rate of Wuchang rice includes a bin body and a support frame. The support frame is set at the lower end of the bin body. A receiving hopper is set at the top of the bin body, and a conical finished rice discharge hopper is set at the bottom of the bin body. A support column is welded to the center of the inner surface of the top of the bin body. A spiral slide is wrapped around the support column, and the inner edge of the spiral slide is welded to the support column. A rice-blocking eave is set at the outer edge of the spiral slide. A mesh screen is fixed at the bottom of the support column. The upper end of the spiral slide corresponds to the receiving hopper, and the lower end of the spiral slide is connected to the mesh screen. The mesh screen is inclinedly set inside the bin body, and the lower end of the mesh screen is connected to the bin body. The first rice discharge outlet is set in the middle. The upper part of the mesh screen is where it connects to the spiral slide. The broken rice discharge hopper is set directly below the mesh screen. The second rice discharge outlet is set between the broken rice discharge hopper and the silo body. A baffle is set between the first and second rice discharge outlets. The baffle surrounds the silo body between the mesh screen and the broken rice discharge hopper to form a broken rice silo and a finished rice discharge channel. The silo body below the broken rice discharge hopper is the finished rice silo. The finished rice discharge channel is connected to the finished rice silo. The broken rice outlet pipe is set at the lower end of the broken rice discharge hopper. The broken rice outlet pipe passes through the finished rice discharge hopper. The finished rice discharge outlet is set at the lower end of the finished rice discharge hopper.

[0006] In the above scheme, the mesh screen is installed on the upper part of the silo body.

[0007] In the above scheme, a pull-out baffle is installed at the broken rice outlet pipe. The pull-out baffle is located below the finished rice discharge hopper and is used to adjust whether broken rice is discharged and the speed of broken rice discharge.

[0008] In the above scheme, a pull-out baffle is installed at the finished rice discharge port. This pull-out baffle is used to adjust whether finished rice is discharged and the discharge speed of finished rice.

[0009] The above scheme includes cleaning openings in the warehouse walls to facilitate observation of rice levels and cleaning of the rice storage warehouse.

[0010] This utility model has the following beneficial effects: 1. In this utility model, the receiving hopper corresponds to the upper end of the spiral slide. After the elevator puts rice into the receiving hopper, the rice slides along the spiral slide into the upper half of the inclined mesh screen instead of falling directly into the bottom of the bin, which reduces the formation of broken rice. When the rice slides down the mesh screen, the broken rice falls from the mesh screen into the broken rice bin, and the finished rice falls from the first finished rice outlet along the finished rice outlet into the finished rice bin, thus completing the classification of broken rice and finished rice.

[0011] 2. This utility model is particularly suitable for the storage of Wuchang rice from Northeast China, in order to solve the problem that Wuchang rice is prone to broken rice and reduced polished rice rate when stored in rice storage warehouses. Attached Figure Description
