Description

Automatic grain leveling device

Technical Field

The utility model relates to a grain storage technical field specifically indicates automatic flat grain device.

Background

Grain warehousing of the horizontal warehouse generally adopts a grain conveyor with a steering mechanism, and grain is conveyed to each position of the warehouse through the grain conveyor. Because the storehouse area is great, the grain conveyer transports grain and can form the toper grain heap of countless height difference, and later stage needs level and smooth the grain face, also is the last process of grain storage. The following problems exist in the prior art: first, the existing grain conveyors do not have a grain leveling function. Secondly, at present, the machines and equipment for leveling the grain surface at home and abroad are few, and the machines and equipment are mainly divided into a fixed grain leveling machine and a movable grain leveling machine. The fixed grain leveling machine is usually fixed at the top of a granary to perform grain leveling work, and the work is time-consuming and low in precision. The movable grain leveling machine is generally driven by taking a crawler as a chassis, the upper body levels grains, the problems of complex structure, high cost, poor stability and the like exist, and the movable grain leveling machine is more difficult to work and has low efficiency under the condition of complex fluctuation of grain surface.

Disclosure of Invention

The utility model provides an automatic flat grain device to solve the above-mentioned problem that exists among the prior art.

The utility model adopts the following technical scheme:

the automatic grain leveling device comprises a machine base and a grain leveling plate, wherein the grain leveling plate can be horizontally and rotatably arranged on the machine base and is provided with a driving device for enabling the grain leveling plate to rotate.

Further, the base is a grain conveyor, a hoisting frame is arranged at the discharge end of the grain conveyor, the hoisting frame is provided with the driving device mainly comprising a motor and a gearbox, and an output shaft of the gearbox is connected with the grain leveling plate.

And the device further comprises a first sensor for detecting the height of the grain pile at the blanking point and controlling the start and stop of the driving device.

Further, the first sensor is an infrared distance measuring sensor.

Furthermore, a second sensor for detecting surrounding grains and controlling the starting and stopping of the driving device is arranged at the end part of the grain leveling plate.

Further, the second sensor is a pressure sensor.

From the above description of the structure of the present invention, compared with the prior art, the present invention has the following advantages:

firstly, the utility model arranges the flat grain plate on the hoisting frame at the discharge end of the grain conveyor in a horizontally rotatable manner, and is provided with the driving device for rotating the flat grain plate, so that the chassis part in the traditional movable grain leveling machine is not needed, the flat grain plate is directly refitted by the existing grain conveyor, the cost is saved, the structure is simple, and the flat grain plate can still work under the condition of complex fluctuation of the grain surface; and can make flat grain board rotate in grain blanking point center through adjustment hoist and mount frame, the precision is higher, and efficiency is higher.

And secondly, the utility model discloses a first sensor for detect the blanking point grain heap height and control drive arrangement and open and stop, in time open and stop flat grain board, save the cost.

Thirdly, the utility model discloses a second sensor is installed in the tip of flat grain board for grain and control drive arrangement around the detection open and stop, in time open and stop flat grain board, save the cost.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

The following describes embodiments of the present invention with reference to the drawings.

Referring to fig. 1, the automatic grain leveling device comprises a base 1, wherein the base 1 is a grain conveyor, a discharge end 11 of the grain conveyor is provided with a hoisting frame 2, the hoisting frame 2 is provided with a driving device 3 mainly comprising a motor 31 and a gearbox 32, an output shaft of the gearbox 32 is connected with a grain leveling plate 4, and the driving device 3 enables the grain leveling plate to horizontally rotate.

Referring to fig. 1, a first sensor 6 for detecting the height of the grain pile at the blanking point and controlling the start and stop of the driving device 3 is arranged on the hoisting frame 2. The first sensor 6 may be an infrared distance measuring sensor.

Referring to fig. 1, a second sensor 5 for detecting surrounding grains and controlling the start and stop of the driving device 3 is installed at the end of the grain leveling plate 4. The second sensor 5 may be a pressure sensor.

The utility model discloses a theory of operation: the grain conveyor conveys grains to form a conical grain pile at a blanking point, and the first sensor 6 (an infrared distance measuring sensor) detects the height of the grain pile at the blanking point, namely the distance from the grain pile at the blanking point. When the first sensor 6 detects that the distance is smaller than a certain value, the motor 31 in the driving device 3 is started, the gearbox 32 decelerates to drive the flat grain plate 4 to rotate, and at the moment, the end part of the flat grain plate 4 is not in contact with the grain pile. The grain pile is continuously heightened along with the continuous grain conveying of the grain conveyor, the grain positioned in the center of the grain leveling plate 4 is scattered outwards due to the rotation of the grain leveling plate 4, and the conical grain pile is leveled into the grain surface. When the second sensor 5 (pressure sensor) installed at the end of the grain leveling plate 4 detects a certain pressure, the motor 31 in the driving device 3 is stopped, and the grain leveling plate 4 is stopped accordingly. At the moment, the grain height at the end part of the grain leveling plate 4 is the same as that of the grain at the center of the grain leveling plate 4, and the grain surface is leveled. The grain conveyor automatically turns to a new grain falling point, and the process is repeated.

The above-mentioned be the utility model discloses a concrete implementation way, nevertheless the utility model discloses a design concept is not limited to this, and the ordinary use of this design is right the utility model discloses carry out immaterial change, all should belong to the act of infringement the protection scope of the utility model.
