Description

Technical Field

[0001] The invention relates to the technical field of a grain feeding device for a scraper conveyor, and in particular to a grain feeding device for an adjustable scraper conveyor. Background Art

[0002] The transportation device for grain storage is a key facility to ensure the efficient circulation of grain. It covers a variety of types, each with its own unique advantages and applicable scenarios. The most common one is the belt conveyor, which has a relatively simple structure and is mainly composed of conveyor belts, drive rollers, rollers and other components. The conveyor belt has high strength and wear resistance, can stably carry a large amount of grain, and realize continuous transportation. When working, the drive roller drives the conveyor belt to rotate in a cycle, and the rollers support the conveyor belt to keep it flat. The grain is evenly laid on it from one end, and can be transported to the designated location continuously. It is widely used in short-distance transportation within the grain depot and loading and unloading links in grain processing workshops. Bucket elevators specialize in vertical grain transportation. It looks like a "dragon" climbing up. The outer shell of the machine body is equipped with a bucket, which is pulled by a chain or belt to circulate, scoop up grain from the bottom, and climb along the track to a high place for unloading. This device has good sealing performance and can effectively prevent grain scattering and dust pollution. It is suitable for lifting low-lying grain to high-rise storage in the granary, greatly improving the utilization rate of storage space. There are also scraper conveyors, which rely on the combination of scrapers and chains to scrape and transport grain in a closed casing. They can adapt to the transportation needs at different angles. Whether it is horizontal, inclined or vertical transportation at small angles, it can complete the grain handling task accurately and efficiently, providing solid guarantees for all aspects of grain storage and transportation.

[0003] The grain inlet of traditional scraper conveyors mostly uses a single motor to drive the valve, which is either normally open or normally closed, which can easily cause the scraper conveyor to become blocked. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides an adjustable grain feeding device for a scraper conveyor, which solves the problem that most traditional grain feeding ports of scrapers adopt a single motor-driven valve, which is either normally open or normally closed, thus easily causing blockage of the scraper conveyor.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: an adjustable scraper grain feeding device, comprising a grain silo unloading motor driven valve device, a grain feeding middle section buffer device and a scraper machine trough body matching device, the bottom of the grain silo unloading motor driven valve device is fixedly connected to the top of the grain feeding middle section buffer device, the top of the grain feeding middle section buffer device is fixedly connected to the top of the scraper machine trough body matching device, the grain silo unloading motor driven valve device is used to limit the entry state of grain, after the grain enters the grain feeding middle section buffer device through the grain silo unloading motor driven valve device, the grain flow is adjusted by the grain feeding middle section buffer device, and then the grain adjusted by the grain feeding middle section buffer device is continued to be transported by the scraper machine trough body matching device.

[0006] Preferably, the fastening structure includes screws, and the grain silo unloading motor-driven valve device includes a motor driving device and a grain unloading port connecting piece, the top of the motor driving device is fixedly connected to the bottom of the conical-bottom grain silo, and the bottom of the grain unloading port connecting piece is fixedly connected to the bottom of the motor driving device. A valve plate and a PLC control unit are arranged on the top of the motor driving device, and the valve plate is bent. The PLC control unit is used to control the valve switch, and the motor driving device is fixedly connected to a motor at a rear position, and a transmission shaft is fixedly arranged at the output end of the motor, and a gear is fixedly connected to the end of the transmission shaft away from the output end of the motor, and the gear is meshed with teeth inside the valve.

The flow control handle is fixedly arranged inside the middle-section frame and its cover plate, and the flow control panel is fixedly arranged on the outside of the middle-section frame and its cover plate. The middle-section frame and its cover plate are used to shield the grain, and the flow control panel is used to adjust the angle of the flow control handle, and changing the angle of the flow control handle is used to change the thickness of the grain.

[0009] Preferably, a buffer wear-resistant plate made of PE material is fixedly connected to the surface of the flow control handle.

[0010] Preferably, the middle frame and the cover plate thereof are provided with a bending edge, and are fixed to the side walls of the middle frame and the cover plate thereof by bolts.

[0011] Preferably, the scraper conveyor trough matching device includes a scraper conveyor trough matching frame, a grain input support plate, a trough observation window and a grain taking device. The scraper conveyor trough matching frame is fixedly connected to the bottom of the middle frame and its cover plate, the grain input support plate is fixedly connected to the upper inner position of the scraper conveyor trough matching frame, and the side wall of the scraper conveyor trough matching frame is provided with a grain taking device and a trough observation window. The grain input support plate is used to receive the grain after the flow is limited by the grain input middle buffer device and to stratify the grain. The trough observation window is used to observe the internal grain transportation status, and the grain taking device is used to take out the grain in transit.

[0012] Preferably, the scraper trough body and the bottom of the frame are fixedly connected with a buffer wear-resistant plate made of PE material, and the top of the grain inlet support plate is fixedly connected with a buffer wear-resistant plate made of PE material.

[0013] Working principle: The motor in the motor drive device directly drives the gear to drive the valve to open. The grain passes through the valve and the grain unloading connector to reach the middle buffer device of the grain input. It is accumulated in a small range here through the grain input tray. The scraper chain scraper passes through the grain input tray and moves the grain. The flow control handle is adjusted to multiple gears on the flow control panel to control the thickness of the grain taken away by the scraper chain. The grain falls to the bottom layer of the scraper trough matching device through the grain taking device, and continues to be transported by the single chain scraper of the scraper, and continues to be transported through the trough observation window.

[0014] The present invention provides a grain feeding device for an adjustable scraper, which has the following beneficial effects:

[0015] 1. In the present invention, grain is accumulated in a small range through the buffer device in the middle section of the grain inlet, the flow rate is controlled by the flow control handle, and then the grain is transported to the next layer in time through the scraper chain scraper, which ensures the transportation of grain while reducing the blockage of the scraper caused by a large amount of accumulation, thereby improving the problem that most traditional scraper grain inlets use a single motor to drive the valve, which is either normally open or normally closed, and is very likely to cause the scraper to be blocked.

[0016] 2. In the present invention, multiple flow rates are conveyed, the mechanism is fully enclosed, waterproof and rainproof, the structure is simple, and installation and disassembly are convenient, which saves costs and reduces the difficulty of repair and maintenance.

[0017] 3. In the present invention, the unloading valve is controlled by direct motor drive and gear meshing, which has a simple structure and reduces malfunction problems. The valve is thickened and the valve plate is bent to ensure the long-term working pressure resistance of the bottom of the granary. A PE material buffer wear-resistant plate is installed at the grain inlet to improve the wear resistance.

[0018] 4. In the present invention, the cover plate is bent and bolted to the frame, which not only ensures the overall waterproof and rainproof sealing performance, but also allows timely disassembly and maintenance when problems are found, and also prevents the external tension of grain on the device from causing overall deformation of the device. The grain taking device is fixed with a screw handle, which is convenient for taking grain at any time. The tank observation window can make corresponding countermeasures in time according to the grain unloading situation, improve work efficiency, and reduce unnecessary losses.

DETAILED DESCRIPTION

[0024] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Embodiment 1:

[0026] Please see attached Figure 1 -Attached Figure 4The embodiment of the present invention provides an adjustable grain feeding device of a scraper, comprising a grain bin unloading motor driven valve device 100, a grain feeding middle section buffer device 200 and a scraper tank body matching device 300. The bottom of the grain bin unloading motor driven valve device 100 is fixedly connected to the top of the grain feeding middle section buffer device 200, and the top of the grain feeding middle section buffer device 200 is fixedly connected to the top of the scraper tank body matching device 300. The grain bin unloading motor driven valve device 100 is used to limit the entry state of grain. After the grain enters the grain feeding middle section buffer device 200 through the grain bin unloading motor driven valve device 100, the grain flow rate is adjusted by the grain feeding middle section buffer device 200, and then the grain passing through the scraper tank body matching device 300 is adjusted by the grain feeding middle section buffer device 200.

[0027] Specifically, the grain unloading motor-driven valve device 100 can control the inflow of grain, the grain inlet mid-section buffer device 200 can change the amount of grain entering, and the scraper trough matching device 300 can transport and observe the grain.

[0028] Please see attached Figure 2 -Attached Figure 4 The grain silo unloading motor-driven valve device 100 includes a motor driving device 110 and a grain unloading port connecting piece 120. The top of the motor driving device 110 is fixedly connected to the bottom of the conical-bottom grain silo, and the bottom of the grain unloading port connecting piece 120 is fixedly connected to the bottom of the motor driving device 110. A valve plate and a PLC control unit are arranged on the top of the motor driving device 110. The valve plate is bent, and the PLC control unit is used to control the valve switch. The motor driving device 110 is fixedly connected to a motor at the rear position, and a transmission shaft is fixedly arranged at the output end of the motor. A gear is fixedly connected to the end of the transmission shaft away from the output end of the motor, and the gear is meshed with the teeth inside the valve.

[0029] Specifically, the valve plate can control the opening and closing of the grain entry channel, adjust the grain flow, and withstand the pressure at the bottom of the granary to ensure stable operation of the device. At the same time, the valve is thickened and the PLC control unit plays an intelligent control role in the motor drive device 110 to accurately coordinate the opening and closing of the valve, thereby achieving precise control of the grain entry state and flow, and ensuring the stability and order of the entire grain entry process. The bent shape of the valve plate can enhance its structural strength, so that it can effectively resist the impact of grain flow and the grain pressure of the granary under the special working conditions at the bottom of the conical bottom granary. The motor can output torque to drive the transmission shaft and the gears connected to it to rotate, thereby accurately controlling the opening and closing of the valve plate.

[0030] Please see attached Figure 1 -Attached Figure 3 A rubber sheet is fixedly arranged at the output port of the motor.

[0031] Specifically, it can play a role in sealing, buffering and reducing wear, preventing grain particles or impurities from entering the motor and affecting its performance, while reducing the vibration during motor output, extending the service life of the motor and the entire device, and ensuring stable operation of the device.

[0032] Please see attached Figure 1 -Attached Figure 3 The grain inlet middle buffer device 200 includes a flow control handle 220, a middle frame and its cover plate 210, and a flow control panel 230. The flow control handle 220 is fixedly arranged inside the middle frame and its cover plate 210, and the flow control panel 230 is fixedly arranged on the outside of the middle frame and its cover plate 210. The middle frame and its cover plate 210 are used to shield the grain, and the flow control panel 230 is used to adjust the angle of the flow control handle 220. Changing the angle of the flow control handle 220 is used to change the thickness of the grain.

[0033] Specifically, the middle section frame and its cover plate 210 serve to construct a stable structure and shield the grain to prevent it from overflowing and mixing with foreign impurities. At the same time, the bent edge of the cover plate and the bolt fixing method ensure that the device is well sealed and easy to disassemble and maintain, providing reliable guarantee for the normal operation of the middle section buffer device 200 for grain entry. The flow control handle 220 changes its angle under the adjustment of the flow control panel 230, so as to accurately control the accumulation thickness of the grain in the middle section buffer device 200 for grain entry, thereby achieving effective regulation of the grain flow, ensuring a smooth and efficient grain transportation process, and adapting to different grain entry needs. The flow control panel 230 can provide the operator with an intuitive operation interface, and the grain flow can be accurately controlled by accurately adjusting and setting the angle of the flow control handle 220.

[0034] Please see attached Figure 1 -Attached Figure 3 A PE buffer wear-resistant plate is fixedly connected to the surface of the flow control handle 220 .

[0035] Specifically, during the process of frequent contact and adjustment with the grain, the handle can effectively reduce the wear of the grain on the handle, enhance its durability, and at the same time play a buffering role to prevent the grain from being damaged due to collision.

[0036] Please see attached Figure 1 -Attached Figure 4 The middle frame and its cover plate 210 are provided with a bending edge at their cover plates, and are fixed to the side walls of the middle frame and its cover plate 210 by bolts.

[0037] Specifically, this can effectively enhance the sealing performance of the device, prevent grain leakage and intrusion of foreign matter, and facilitate disassembly and maintenance.

[0038] Please see attached Figure 1 -Attached Figure 4 The scraper conveyor trough body matching device 300 includes a scraper conveyor trough body matching frame 310, a grain input support plate 320, a trough body observation window 330 and a grain taking device 340. The scraper conveyor trough body matching frame 310 is fixedly connected to the bottom of the middle frame and its cover plate 210. The grain input support plate 320 is fixedly connected to the upper position inside the scraper conveyor trough body matching frame 310. The side wall of the scraper conveyor trough body matching frame 310 is provided with a grain taking device 340 and a trough body observation window 330. The grain input support plate 320 is used to receive the grain after the flow is limited by the grain input middle section buffer device 200 and to stratify the grain. The trough body observation window 330 is used to observe the internal grain transportation status. The grain taking device 340 is used to take out the grain in transit.

[0039] Specifically, the scraper trough cooperates with the frame 310 to connect and support various components, providing a stable installation foundation for the grain feeding support plate 320, the grain taking device 340, the trough observation window 330, etc. The grain feeding support plate 320 receives the grain after the flow is limited by the grain feeding middle buffer device 200, layers the grain to prevent accumulation and blockage, and reduces the two-way squeezing and crushing of the grain by the upper and lower scraper chains. At the same time, the scraper chain scraper realizes the smooth transportation of grain, ensures the efficient circulation and stable quality of grain in the grain feeding process, and the observation window 330 of the trough body is used to check the grain feeding process. 0 can provide an intuitive visual status of grain in the process of transportation in the scraper trough matching device 300 in real time, so that the operator can find abnormal conditions in time, such as grain accumulation, blockage or poor transportation, so as to take corresponding measures to adjust and deal with them. The grain taking device 340 can conveniently and quickly take out grain samples in transportation during the operation of the scraper, so as to timely detect the humidity, quality and other parameters of the grain. At the same time, the grain in transportation can also be taken in an appropriate amount when necessary, ensuring that quality monitoring and emergency operations in the grain transportation process can be effectively implemented.

[0040] Please see attached Figure 1 -Attached Figure 3 The bottom of the scraper trough body and the frame 310 are fixedly connected with a PE buffer wear-resistant plate, and the top of the grain inlet support plate 320 is fixedly connected with a PE buffer wear-resistant plate.

[0041] Specifically, during the grain transportation process, this can not only reduce the friction and wear between the grain and the device components, protect the structural integrity of the device, and extend the service life, but also cushion the impact force when the grain falls or moves, and reduce the grain breakage rate.

[0042] 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.
