Description

Technical Field

[0001] This application relates to the field of grain machinery technology, and in particular to a rice silo unloading structure. Background Technology

[0002] Rice husks are an important raw material in baijiu (Chinese liquor) brewing, making their storage and transportation efficiency particularly crucial. Rice silos are buildings or facilities specifically designed for storing rice. Their design aims to maintain the stability of rice quality during storage and prevent problems such as mold and pests. Conveyor storage, due to its efficiency and space-saving characteristics, has gradually replaced traditional flat storage methods.

[0003] When existing rice silos are in use, rice husks are prone to arching inside the silos due to factors such as high internal friction, poor fluidity, and improper storage environment. This not only restricts the smooth discharge of rice husks and affects production efficiency, but may also lead to safety accidents. Utility Model Content

[0004] In view of the shortcomings of the prior art, this application provides a rice silo discharge structure that overcomes the deficiencies of the prior art. It aims to solve the problem that when rice husks are used, they tend to arch inside the silo due to factors such as high internal friction, poor fluidity, and improper storage environment. This not only restricts the smooth discharge of rice husks and affects production efficiency, but may also lead to safety accidents.

[0005] To achieve the above objectives, this application provides the following technical solution: a rice silo discharge structure, comprising a base, a rice silo fixedly installed on the top of the base, a discharge hopper fixedly connected to the lower end of the rice silo, a plurality of blow-block valves fixedly installed on the side wall of the discharge hopper, and an air cannon connected to the discharge hopper through the blow-block valves; a vibration unit fixedly installed on the outer wall of the discharge hopper near the lower end, the vibration unit comprising a mounting box fixedly installed on the outer wall of the discharge hopper, a vibration motor disposed inside the mounting box, a spring fixedly connected to one end of the vibration motor near the discharge hopper, a vibration plate fixedly connected to the other end of the spring and conforming to the outer wall of the discharge hopper, a discharge valve fixedly installed at the lower end of the discharge hopper, and a screw conveyor fixedly installed at the lower end of the discharge valve.

[0006] By adopting the above technical solution, the feeding hopper is connected to an external air cannon via a blow-block valve to form an automatic spraying system for breaking up arches. The air cannon converts air pressure energy into air jet kinetic energy, which is then input into the feeding hopper through the blow-block valve to generate a strong impact force to break up the arches, allowing the rice to be fed smoothly. The vibrating motor amplifies the amplitude through a spring and then transmits the vibration force to the outer wall of the feeding hopper through a vibrating plate, applying vibration to the rice inside the feeding hopper to prevent the rice from clogging inside the feeding hopper and to help speed up the feeding speed. By installing a screw conveyor, the automation level of the discharge is improved.

[0007] As a preferred technical solution of this application, the rice silo includes a concrete cone bottom and a steel silo. The bottom wall of the concrete cone bottom is fixedly installed on the base by a support frame. The top of the concrete cone bottom is fixedly connected to a concrete ring beam by a concrete column. The steel silo is fixedly installed inside the concrete ring beam, and the concrete cone bottom is located at the bottom of the steel silo.

[0008] By adopting the above technical solution, the concrete cone bottom is fixed to the base through the support frame, which transmits the lateral pressure of the grain to the base, preventing the rice silo from being deformed by pressure. The concrete ring beam and concrete column form a rigid frame to support the vertical load of the steel silo, which significantly improves the overall anti-overturning ability.

[0009] As a preferred technical solution of this application, a fixing seat is fixedly installed on the inner wall of the mounting box, the vibration motor is fixedly installed on the top of the fixing seat, and a support block is fixedly connected to the bottom of the mounting box.

[0010] By adopting the above technical solution, the vibration motor is limited and fixed by setting a fixed seat, ensuring that the vibration motor can be stably installed inside the mounting box. The support block plays a role in reinforcement and support, so that the mounting box can be stably installed on the outer wall of the hopper.

[0011] As a preferred technical solution of this application, the screw conveyor includes a conveying bin, a screw conveying shaft is rotatably connected inside the conveying bin, a drive motor for driving the screw conveying shaft to rotate is fixedly installed on the side wall of the conveying bin, a conveying inlet is opened on the upper surface of the conveying bin below the discharge valve, and a conveying outlet is opened on the side of the upper surface of the conveying bin away from the conveying inlet.

[0012] By adopting the above technical solution, rice enters the conveying bin through the conveying inlet, and the drive motor drives the screw conveyor shaft to rotate, generating axial thrust on the rice to transport it out of the conveying outlet.

[0013] As a preferred technical solution of this application, the top of the rice silo is provided with a feed inlet, and a sealing cover is placed on the feed inlet.

[0014] By adopting the above technical solution, rice is added to the rice silo through the feed inlet, and the feed inlet is sealed with a sealing cover to ensure the airtightness of the rice silo.

[0015] As a preferred technical solution of this application, a fence is fixedly installed on the top of the rice silo, and a staircase is fixedly installed on the side wall of the rice silo.

[0016] By adopting the above technical solution, workers can climb the stairs to the top of the rice silo to open the sealed cover, and the fence serves as a safety protection.

[0017] As a preferred technical solution of this application, the side wall of the rice silo is provided with an inspection hole on one side of the stairs, and an inspection cover is threadedly connected to the opening of the inspection hole.

[0018] By adopting the above technical solution, the staff unscrewed the inspection cover and then removed the tools into the inspection hole to tamp and break up the rice in the rice silo.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: In this invention, the feeding hopper is connected to an external air cannon via a blow-block valve to form an automatic spraying system for breaking up arches. The air cannon converts air pressure energy into air jet kinetic energy, which is then input into the feeding hopper through the blow-block valve to generate a strong impact force, thereby breaking up the arches and allowing the rice to be fed smoothly. The vibrating motor amplifies the amplitude through a spring and then transmits the vibration force to the outer wall of the feeding hopper through a vibrating plate, applying vibration to the rice inside the feeding hopper. This prevents the rice from clogging inside the feeding hopper and helps to speed up the feeding process. By installing a screw conveyor, the automation level of the discharge is improved.
