Description

Technical Field

[0001] The present invention relates to the technical field of grain storage machinery, and particularly to a multi-functional storage auxiliary machine for a grain flat warehouse. Background Art

[0002] Flat warehouses are the most widely used type of granaries in the existing granaries in China. Flat warehouses have the advantages of low construction cost, short construction period, strong adaptability, etc., and are thus widely adopted. With the rapid development of China's economy, the living standards of the people have been continuously improved, the labor cost has increased year by year, and the construction standards of grain storage flat warehouses have also been continuously improved. Generally, a grain storage flat warehouse includes three parts: a warehouse roof, a wall, and a foundation. High-rise flat warehouses account for about 80% of the granary types constructed by grain storage enterprises in China due to their advantages of safe and reliable structure, low cost, and simple construction.

[0003] For the grain intake of the bays in the flat warehouse, traditionally, a mobile conveyor is used to convey part of the grain through the large door, and the grain above the large door is supplemented through the side wall ventilation windows. The equipment traditionally used for grain outloading mainly consists of a mobile grain raking machine, a horizontal conveyor, a lifting and telescopic conveyor, etc. These mobile devices often have the disadvantages of large floor area, large auxiliary workload, and inability to achieve centralized automatic control, and also need to build a special mechanical shed for placement; moreover, during the process of grain in and out of the warehouse, the equipment needs to be frequently moved and adjusted, consuming a large amount of labor and time, and the actual working time is only about 50%.

[0004] The mobile conveyor has a large labor intensity, a large amount of dust, seriously exceeding the emission standard, and low efficiency. The grain supplemented through the window forms a small mountain pile, which requires manual leveling of the grain surface, with a large labor intensity and certain safety hazards. Now, with the shortage of labor, it is very difficult to find manpower, and even if found, they are mostly elderly people approaching retirement age, facing the situation of no successors.

[0005] With the continuous development of the social economy, the gradual shortage of the labor force, and the increasing requirements for the protection of workers' working environments, the traditional relatively extensive material in-and-out warehouse operation method can no longer meet the requirements of the current economic development situation. Currently, in newly built tall flat warehouses, grain inlet openings are set at the top of the granaries, and the fixed mechanical grain inlet method combining bucket elevators and scraper conveyors (or air cushion belt conveyors) has gradually become the development direction of grain inlet operations. For this reason, the inventors of this application have developed an automated in-and-out warehouse technology for granular materials in flat warehouses. For example: Chinese Patent: Automated In-and-Out Warehouse Method for Granular Materials in Flat Warehouses, Application No.: 201310700953.4, Application Date: December 16, 2013, Abstract: The present invention discloses an automated in-and-out warehouse method for granular materials in flat warehouses. The main equipment used includes bucket elevators, longitudinal screw conveyors, transverse screw conveyors, and corresponding controllers. When feeding into the warehouse, the materials in the feeding hopper outside the warehouse are transported into the warehouse through the bucket elevator, and then the longitudinal screw conveyor and the transverse screw conveyor cooperate closely to complete the material inlet and leveling operations in the warehouse; during the out-warehouse operation, the discharge gate valve in the warehouse is opened to transmit the materials through the pipeline to the outside of the warehouse and the bucket elevator is used for lifting and transporting to the next process. At the same time, the transverse screw conveyor and the longitudinal screw conveyor cooperate to transport the materials on each layer in the warehouse to the discharge opening in the warehouse to complete the out-warehouse operation of the materials. Through the reasonable selection and layout of the flat warehouse and the corresponding equipment, this technology facilitates the realization of mechanized and automated in-and-out warehouse operations for granular and powdery materials, can significantly reduce labor costs, and improve the operation efficiency of material in-and-out warehouses.

[0006] Through applied research, it is found that although the above-mentioned automated in-and-out warehouse technology for granular materials in flat warehouses can achieve automatic leveling and reduce grading, and reduce labor intensity, the screw conveyor it uses is suspended by steel wires, and the screw conveyor is prone to swing during operation, resulting in poor leveling effect, and it needs to be used in conjunction with the equipment in the warehouse, with high requirements for the operation skills of workers. And when condensation and hardening occur on the grain surface, it is impossible to turn the warehouse, and manual operation of handheld machinery is required for additional turning of the warehouse. Therefore, it is necessary to set up an integrated multi-functional storage auxiliary machine for grain flat warehouses to achieve the above functions simultaneously. Summary of the Invention

[0007] The purpose of the present invention is to provide a multi-functional storage auxiliary machine for grain flat warehouses, which has the functions of transporting grain in the warehouse, preventing grading, leveling the grain surface, turning the surface layer of the grain surface, and assisting the out-warehouse operation.

[0008] In order to achieve the purpose of the present invention, the technical solution adopted is: A multi-functional storage auxiliary machine for a grain bungalow warehouse, comprising guide rails, an inlet grain screw conveyor, and a transverse screw conveyor. The guide rails are respectively installed in parallel at the same height on the left and right longitudinal walls of the bungalow warehouse. A end beam is installed on the guide rails through moving pulleys. A cross beam is horizontally connected across between the two side end beams. The moving pulley is connected with a motor driving device for driving the whole end beam and cross beam to move on the guide rails. The inlet grain screw conveyor is longitudinally and fixedly installed at the bottom of the cross beam near the grain inlet of the warehouse. The transverse screw conveyor is horizontally suspended below the cross beam by a winch. The transverse screw conveyor is connected with the cross beam through a structural scissor-type telescopic frame. The scissor-type telescopic frame adopts the bracket of a scissor-type elevator. The lower end of the scissor-type telescopic frame is connected with the casing frame of the transverse screw conveyor, and the upper end of the scissor-type telescopic frame is connected with the cross beam. The end of the transverse screw conveyor near the grain outlet of the warehouse is fixedly connected with a longitudinally arranged outlet grain screw conveyor, which moves up and down with the transverse screw conveyor. The above-mentioned screw conveyors all adopt bottomless screw conveyors, that is, the screw conveyor shaft can directly contact the material through the casing frame.

[0009] Further preferably: The guide rails are connected with the longitudinal wall of the bungalow warehouse through support legs, and the support legs can stably install the guide rails on the longitudinal wall of the bungalow warehouse.

[0010] Further preferably: Two parallel cross beams are horizontally connected across between the two side end beams. A moving trolley that can move on the two cross beams driven by a motor is installed between the two cross beams. A negative pressure grain suction device is installed on the moving trolley. By controlling the moving trolley to drive the negative pressure grain suction device to move for sampling, the labor intensity of sampling is reduced. And when discharging grain, the residual grain and dust in the warehouse can be sucked and cleaned by the suction pipe of the negative pressure grain suction device, improving the work efficiency. The negative pressure grain suction device can adopt the structure of a suction type sampler. After the negative pressure grain suction device is fixedly installed on the casing frame, it can extract grain samples through a metal pipe, assist the air pipe of the single-tube fan to insert into the grain pile and insert the temperature measuring cable, without the need for manual holding of the sampler, reducing the labor intensity. When discharging grain, the suction pipe of the negative pressure grain suction device can be externally connected with an extension pipe to suck and clean the residual grain and dust in the warehouse, avoiding the harm of dust suffered by manual cleaning, and at the same time improving the work efficiency. Preferably: The transverse screw conveyor is suspended at the bottom between the two cross beams and is prevented from swinging through a scissor-type telescopic frame Further preferably: the incoming grain screw conveyor, the transverse screw conveyor, and the outgoing grain screw conveyor each include a driving motor, a speed reducer, a casing frame, and a screw conveyor shaft. Screw blades are installed on the screw conveyor shaft. The casing frame is in the shape of an arc groove with an open bottom. The casing frame can also adopt a frame structure as long as it can support and install the screw conveyor shaft. The screw conveyor shaft is rotatably installed in the casing frame through a pedestal bearing. The screw conveyor shaft is arranged along the length direction of the casing frame. One end of the screw conveyor shaft is connected to the driving motor through a speed reducer. The incoming grain screw conveyor, the transverse screw conveyor, and the outgoing grain screw conveyor are all bottomless screw conveyors. The screw conveyor shaft can extend out of the casing frame, and the screw blades on the screw conveyor shaft are used to turn and rake the grain for conveying.

[0011] The multi-functional storage auxiliary machine for this grain flat warehouse controls the transverse screw conveyor to move up and down according to the height of the grain pile through a winch. The scissor-type telescopic frame can ensure the normal lifting of the transverse screw conveyor while avoiding the working swing of the transverse screw conveyor. When incoming grain, the grain falls from the grain inlet of the granary. The transverse screw conveyor deflects the grain horizontally. When the grain rises to the incoming grain screw conveyor, start the incoming grain screw conveyor to work and longitudinally convey the grain between the two grain inlets of the granary. The transverse screw conveyor and the incoming grain screw conveyor cooperate to evenly distribute the grain in the granary, which can reduce grading, has the function of anti-grading operation, and can scrape the grain pile surface, which is beneficial to the subsequent grain storage management work in the granary and has the function of automatic flat storage operation. When the grain surface is caked, use the transverse screw conveyor and the outgoing grain screw conveyor to turn and rake the grain surface to avoid airtightness of the grain surface and has the function of automatic grain turning operation. When the grain is out of the granary, the transverse screw conveyor and the outgoing grain screw conveyor rotate forward and backward as needed to guide the grain far from the grain outlet of the granary to the grain outlet of the granary, which has the function of assisting the grain out operation. In addition, the multi-functional storage auxiliary machine for this grain flat warehouse is provided with two parallel crossbeams. A moving trolley driven by a motor to move on the two crossbeams is installed between the two crossbeams. A negative pressure grain suction device is connected and installed under the moving trolley, which can perform sampling operations and reduce the labor intensity of manual sampling. And after the grain is out of the granary, the suction pipe of the negative pressure grain suction device can be used to suck and clean the residual grain and dust in the granary, improving work efficiency. That is to say, it realizes functions such as assisting the grain out operation, sampling, inserting and pulling out the temperature measuring cable, inserting and pulling out the air duct of the single-tube fan, and cleaning the residual grain and dust in the granary.
